The fair value of an asset should reflect its highest and best use by market participants,&#13;principal (or most advantageous) markets, and an in-use or an in-exchange valuation premise.

The selection and application&#13;of one or more of the techniques may require significant judgment and are primarily dependent upon the characteristics of the asset&#13;or liability, and the quality and availability of inputs. Valuation techniques used to measure fair value under ASC 820 must maximize&#13;the use of observable inputs and minimize the use of unobservable inputs. ASC 820 also provides fair value hierarchy for inputs&#13;and resulting measurement as follows:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Level 1: Quoted prices (unadjusted)&#13;in active markets that are accessible at the measurement date for identical assets or liabilities.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Level 2: Quoted prices for similar&#13;assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active;&#13;inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from or&#13;corroborated by observable market data for substantially the full term of the assets or liabilities; and&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Level 3: Unobservable inputs&#13;for the asset or liability that are supported by little or no market activity, and that are significant to the fair values.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Fair value measurements are&#13;required to be disclosed by the Level within the fair value hierarchy in which the fair value measurements in their entirety fall.&#13;Fair value measurements using significant unobservable inputs (in Level 3 measurements) are subject to expanded disclosure requirements&#13;including a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to&#13;the following: total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings,&#13;and a description of where those gains or losses included in earning are reported in the statement of income.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;The Company records a debt discount&#13;related to the issuance of convertible debts that have conversion features at adjustable rates.

text-align: justify"&gt;The Company accounts Certain&#13;Financial Instruments with Down Round Features based on ASU 2017-11, "Earnings per share: I. Accounting for Certain Financial&#13;Instruments with Down Round Features," which allows companies to exclude a down round feature when determining whether a&#13;financial instrument is considered indexed to the entity's own stock. As a result, financial instruments with down round&#13;features may no longer be required to be accounted classified as liabilities. A company will recognize the value of a down round&#13;feature only when it is triggered, and the strike price has been adjusted downward. For equity-classified freestanding financial&#13;instruments, such as warrants, an entity will treat the value of the effect of the down round, when triggered, as a dividend and&#13;a reduction of income available to common shareholders in computing basic earnings per share.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"&gt;&lt;tr style="vertical-align: top"&gt;&#13;&lt;td style="text-align: justify; width: 0.5in"&gt;&lt;/td&gt;&lt;td style="text-align: justify; width: 0.25in"&gt;&lt;b&gt;O.&lt;/b&gt;&lt;/td&gt;&lt;td style="text-align: justify"&gt;&lt;b&gt;Recent Accounting Pronouncements&lt;/b&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; margin-top: 0pt; margin-bottom: 0pt"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&lt;i&gt;Accounting Pronouncements&#13;Adopted in 2020&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;In June 2016, the Financial&#13;Accounting Standards Board (the "FASB") issued an ASU that supersedes the existing impairment model for most financial&#13;assets to a current expected credit loss model.

This guidance&#13;replaces the current incurred loss impairment methodology. Under the new guidance, on initial recognition and at each reporting&#13;period, an entity is required to recognize an allowance that reflects its current estimate of credit losses expected to be incurred&#13;over the life of the financial instrument based on historical experience, current conditions and reasonable and supportable forecasts.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;The guidance became effective&#13;on January 1, 2020, including interim periods within that year and requires a modified retrospective transition approach through&#13;a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. Under the modified retrospective&#13;method of adoption, prior year reported results are not restated. The Company has performed its analysis of the impact on its financial&#13;instruments that are within the scope of this guidance and has concluded that there was no material impact to its consolidated&#13;financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;In August 2018, the FASB issued&#13;ASU No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Framework &amp;#8212; Changes to&#13;the Disclosure Requirements for Fair Value Measurement" ("ASU No. 2018-13") as part of the FASB's broader&#13;disclosure framework project.

The amendments in this ASU simplify the accounting for income taxes, eliminates certain exceptions to the general&#13;principles in Topic 740 and clarifies certain aspects of the current guidance to improve consistent application among reporting&#13;entities. ASU 2019-12 is effective for fiscal years beginning after December 15, 2021 and interim periods within annual periods&#13;beginning after December 15, 2022, though early adoption is permitted, including adoption in any interim period for which financial&#13;statements have not yet been issued.

ASU&amp;#160;2020-06 will simplify the accounting for&#13;convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible&#13;preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized&#13;from the host contract as compared with current GAAP. Convertible instruments that continue to be subject to separation&#13;models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that&#13;meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2)&#13;convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital.&#13;ASU&amp;#160;2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity's own equity&#13;to reduce form-over-substance-based accounting conclusions. ASU&amp;#160;2020-06 will be effective for public companies for&#13;fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is&#13;permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal&#13;years. The Company is currently evaluating the impact that the adoption of ASU&amp;#160;2020-06 will have on the Company's&#13;consolidated financial statement presentation or disclosures.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Other new pronouncements issued&#13;but not effective as of December 31, 2020 are not expected to have a material impact on the Company's consolidated financial&#13;statements.&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

In assessing the convertible debt instruments, management determines if the convertible&#13;debt host instrument is conventional convertible debt and further if there is a beneficial conversion feature requiring measurement.&#13;If the instrument is not considered conventional convertible debt under ASC 470, the Company will continue its evaluation&#13;process of these instruments as derivative financial instruments under ASC 815.&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Once determined, derivative&#13;liabilities are adjusted to reflect fair value at each reporting period end, with any increase or decrease in the fair value being&#13;recorded in results of operations as an adjustment to fair value of derivatives.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Fair value of certain of the&#13;Company's financial instruments including cash, accounts receivable, account payable, accrued expenses, notes payables, and&#13;other accrued liabilities approximate cost because of their short maturities.

The fair value of an asset should reflect its highest and best use by market participants,&#13;principal (or most advantageous) markets, and an in-use or an in-exchange valuation premise. The fair value of a liability should&#13;reflect the risk of non-performance, which includes, among other things, the Company's credit risk.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Valuation techniques are generally&#13;classified into three categories: the market approach; the income approach; and the cost approach. The selection and application&#13;of one or more of the techniques may require significant judgment and are primarily dependent upon the characteristics of the asset&#13;or liability, and the quality and availability of inputs. Valuation techniques used to measure fair value under ASC 820 must maximize&#13;the use of observable inputs and minimize the use of unobservable inputs. ASC 820 also provides fair value hierarchy for inputs&#13;and resulting measurement as follows:&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Level 1: Quoted prices (unadjusted)&#13;in active markets that are accessible at the measurement date for identical assets or liabilities.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Level 2: Quoted prices for similar&#13;assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active;&#13;inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from or&#13;corroborated by observable market data for substantially the full term of the assets or liabilities; and&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Level 3: Unobservable inputs&#13;for the asset or liability that are supported by little or no market activity, and that are significant to the fair values.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Fair value measurements are&#13;required to be disclosed by the Level within the fair value hierarchy in which the fair value measurements in their entirety fall.&#13;Fair value measurements using significant unobservable inputs (in Level 3 measurements) are subject to expanded disclosure requirements&#13;including a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to&#13;the following: total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings,&#13;and a description of where those gains or losses included in earning are reported in the statement of income.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;The Company records a debt discount&#13;related to the issuance of convertible debts that have conversion features at adjustable rates.

The new guidance requires an entity to recognize an impairment allowance equal&#13;to its current estimate of all contractual cash flows the entity does not expect to collect. The Group adopted this guidance effective&#13;January 1, 2020, with no material impact on its consolidated financial statements&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;In June 2016, the FASB issued&#13;ASU 2016-13, Financial Instruments-Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments. This guidance&#13;replaces the current incurred loss impairment methodology. Under the new guidance, on initial recognition and at each reporting&#13;period, an entity is required to recognize an allowance that reflects its current estimate of credit losses expected to be incurred&#13;over the life of the financial instrument based on historical experience, current conditions and reasonable and supportable forecasts.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;The guidance became effective&#13;on January 1, 2020, including interim periods within that year and requires a modified retrospective transition approach through&#13;a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. Under the modified retrospective&#13;method of adoption, prior year reported results are not restated. The Company has performed its analysis of the impact on its financial&#13;instruments that are within the scope of this guidance and has concluded that there was no material impact to its consolidated&#13;financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;In August 2018, the FASB issued&#13;ASU No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Framework &amp;#8212; Changes to&#13;the Disclosure Requirements for Fair Value Measurement" ("ASU No. 2018-13") as part of the FASB's broader&#13;disclosure framework project. ASU No. 2018-13 removes, modifies and adds certain disclosures, providing greater focus on requirements&#13;that clearly communicate the most important information to the users of the financial statements with respect to fair value measurements.&#13;The adoption of ASU No. 2018-13 as of January 1, 2020 did not have a material impact on the Company's consolidated financial&#13;statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&lt;i&gt;Recently Issued Accounting&#13;Pronouncements Not Yet Adopted&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;In December 2019, the FASB issued&#13;ASU 2019-12, Income Taxes (Topic 740): &lt;font style="font-size: 10pt"&gt;&lt;/font&gt;"Simplifying the Accounting for Income&#13;Taxes." The amendments in this ASU simplify the accounting for income taxes, eliminates certain exceptions to the general&#13;principles in Topic 740 and clarifies certain aspects of the current guidance to improve consistent application among reporting&#13;entities. ASU 2019-12 is effective for fiscal years beginning after December 15, 2021 and interim periods within annual periods&#13;beginning after December 15, 2022, though early adoption is permitted, including adoption in any interim period for which financial&#13;statements have not yet been issued.

ASU&amp;#160;2020-06 will simplify the accounting for&#13;convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible&#13;preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized&#13;from the host contract as compared with current GAAP. Convertible instruments that continue to be subject to separation&#13;models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that&#13;meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2)&#13;convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital.&#13;ASU&amp;#160;2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity's own equity&#13;to reduce form-over-substance-based accounting conclusions. ASU&amp;#160;2020-06 will be effective for public companies for&#13;fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is&#13;permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal&#13;years.

As a result, financial instruments with down round&#13;features may no longer be required to be accounted classified as liabilities. A company will recognize the value of a down round&#13;feature only when it is triggered, and the strike price has been adjusted downward. For equity-classified freestanding financial&#13;instruments, such as warrants, an entity will treat the value of the effect of the down round, when triggered, as a dividend and&#13;a reduction of income available to common shareholders in computing basic earnings per share.&lt;/p&gt;</USDR:CertainFinancialInstrumentsWithDownRoundFeaturesPolicyTextBlock>

Accordingly, each outstanding share of Duke&#13;Inc. common stock was exchanged for the right to receive 1.2421 shares of the Company's common stock (the "Exchange&#13;Ratio"). Of the shares of Duke Inc. common stock that were exchanged for shares of the Company's common stock, 51,410&#13;(representing 63,856 shares of the Company's common stock post-Share Exchange) were issued but remained in escrow until the&#13;Company completed the Short-Form Merger (as defined hereunder). On June 25, 2020, at the closing of the transaction contemplated&#13;by the Merger Agreement, the Company released the shares in escrow.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;As such, at the Effective Time,&#13;the Duke stockholders owned an equivalent of approximately 71% of the Company's common stock. After giving effect to the&#13;Share Exchange, Duke became a subsidiary of the Company. Following the Share Exchange, the Company adopted the business plan of&#13;Duke.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;The transaction was accounted&#13;for as a reverse asset acquisition in accordance with generally accepted accounting principles in the United States of America&#13;("GAAP"). Under this method of accounting, Duke was deemed to be the accounting acquirer for financial reporting purposes.&#13;This determination was primarily based on the facts that, immediately following the Merger: (i)&amp;#160;Duke's stockholders&#13;owned a substantial majority of the voting rights in the combined company, (ii)&amp;#160;Duke designated a majority of the members&#13;of the initial board of directors of the combined company, and (iii)&amp;#160;Duke's senior management holds all key positions&#13;in the senior management of the combined company. As a result of the Recapitalization Transaction, the shareholders of Duke received&#13;the largest ownership interest in the Company, and Duke was determined to be the "accounting acquirer" in the Recapitalization&#13;Transaction. As a result, the historical financial statements of the Company were replaced with the historical financial statements&#13;of Duke. The number of shares prior to the reverse capitalization have been retroactively adjusted based on the equivalent number&#13;of shares received by the accounting acquirer in the Recapitalization Transaction.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;On April 29, 2020, the Company,&#13;Duke Inc. and UAS Sub, executed the Merger Agreement, pursuant to which UAS Sub merged with and into Duke, with Duke surviving&#13;as a wholly-owned subsidiary of the Company (the "Short-Form Merger"). Pursuant to the Merger Agreement, on June 25,&#13;2020, the Company acquired the remaining outstanding shares of Duke held by those certain Duke shareholders that did not participate&#13;in the Share Exchange.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;The COVID-19 pandemic has caused&#13;states of emergency to be declared in various countries, travel restrictions imposed globally, quarantines established in certain&#13;jurisdictions and various institutions and companies being closed. COVID-19 has also adversely affect the Group's ability&#13;to conduct its business effectively due to disruptions to its capabilities, availability and productivity of personnel, while the&#13;Group simultaneously attempts to comply with rapidly changing restrictions, such as travel restrictions, curfews and others. In&#13;particular, on January 24, 2021, the Government of Israel announced that effective January 26, 2021, non-Israeli residents or citizens,&#13;except for non-nationals whose lives are based in Israel, are not allowed to enter Israel, and the number of Israeli citizens permitted&#13;to enter the country per day will be capped at 3,000. In addition, the Ministry of Health in the State of Israel issued guidelines&#13;on March 11, 2020, which were most recently updated in March 2021, recommending people avoid gatherings in one space and providing&#13;that no gathering of more than 20 people should be held under any circumstances. Employers (including the Group) are also required&#13;to prepare and increase as much as possible the capacity and arrangement for employees to work remotely. In addition, on January&#13;25, 2021, the President of the United States issued a proclamation to restrict travel to the United States from foreign nationals&#13;who have recently been in China, Iran, South Africa, and certain European and Latin America countries. Although to date these restrictions&#13;have not impacted the Group's operations, the effect on its business, from the spread of COVID-19 and the actions implemented&#13;by the governments of the State of Israel, the United States and elsewhere across the globe, may worsen over time. The spread of&#13;COVID-19 may also result in the inability of the Group's manufacturers to deliver components or finished products on a timely&#13;basis and may also result in the inability of the Group's suppliers to deliver the parts required by its manufacturers to&#13;complete manufacturing of components or finished products. In addition, governments may divert spending from other budgeted resources&#13;as they seek to reduce and/or stop the spread of COVID-19. Such events may result in a period of business and manufacturing disruption,&#13;and in reduced operations, any of which could materially affect the Group's business, financial condition and results of&#13;operations. The extent to which COVID-19 impacts the Group's business will depend on future developments, which are highly&#13;uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and the actions&#13;to contain COVID-19 or treat its impact, among others. The Group is actively monitoring the pandemic and it is taking any necessary&#13;measures to respond to the situation in cooperation with the various stakeholders.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&lt;b&gt;Going Concern&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;Since inception, the Group has&#13;devoted substantially all its efforts to research and development. The Group is still in its development stage and the extent of&#13;the Group's future operating losses and the timing of becoming profitable, if ever, are uncertain. As of December 31, 2020,&#13;the Group had $105 in cash and cash equivalents, net losses of $1,368, an accumulated deficit of $5,131, and a negative working&#13;capital of $1,176.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;The Group will need to secure&#13;additional capital in the future in order to meet its anticipated liquidity needs primarily through the sale of additional Common&#13;Stock or other equity securities and/or debt financing. Funds from these sources may not be available to the Group on acceptable&#13;terms, if at all, and the Group cannot give assurance that it will be successful in securing such additional capital.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;These conditions raise substantial&#13;doubt about the Group's ability to continue to operate as a "going concern." The Company's ability to continue&#13;operating as a going concern is dependent on several factors, among them is the ability to raise sufficient additional funding.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;The financial statements do&#13;not include any adjustments that might result from the outcome of this uncertainty.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&lt;b&gt;Risk factors&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 0.75in; text-align: justify"&gt;The Group faces a number of&#13;risks, including uncertainties regarding finalization of the development process, demand and market acceptance of the Group's&#13;products, the effects of technological changes, competition and the development of products by competitors. Additionally, other&#13;risk factors also exist, such as the ability to manage growth and the effect of planned expansion of operations on the Group's&#13;future results. In addition, the Group expects to continue incurring significant operating costs and losses in connection&#13;with the development of its products and marketing efforts.&amp;#160;The Group has not yet generated significant revenues from its&#13;operations to fund its activities, and therefore the continuance of its activities as a going concern depends on the receipt of&#13;additional funding from its current stockholders and investors or from third parties.&lt;/p&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

As of March 30, 2021, the New Debentures have an aggregate outstanding principal balance of $200 as a result of conversions of the New Debentures (see note 15 below).</us-gaap:SecuritiesSoldUnderAgreementsToRepurchaseMeasurementDifferenceDescription>

The terms of the Convertible Loan Agreements require repayment of the borrowed amount by the one-year anniversary of the Effective Time, unless, at Company's discretion, and subject to its compliance with any and all terms of the material terms of the Convertible Loan Agreements, the term of such loans is extended for an additional twelve (12) month period. The terms of the Convertible Loan Agreements also provide that the Company may repay any portion of the remaining outstanding loan amount, without penalty, provided, however, that the Company provides the specific lender with three business days' written notice prior to such repayment, during which time the lender may elect to convert any or all of the outstanding loan amount into shares of common stock of the Company. The Convertible Loan Agreements bear simple interest at a rate equal to 15% per annum, payable on the 15th day of each calendar month. On December 9, 2020, the Company utilized its rights under the above agreement and extended the terms of the loans for additional twelve month.</USDR:ConvertibleLoanAgreementDescription>

In the event of a Dilutive Event at any time from the Effective Time through the six (6) month&#13;anniversary of the Effective Time, any such adjustment shall occur immediately after the completion of such period. As of&#13;March 30, 2021, the New Debentures have an aggregate outstanding principal balance of $200 as a result of conversions of the New&#13;Debentures (see note 15 below).&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; margin-top: 0pt; margin-bottom: 0pt"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 1in; text-align: justify"&gt;In accordance with ASC 815-15-25,&#13;the conversion feature was considered an embedded derivative instrument, and is to be recorded at its fair value as its fair value&#13;can be separated from the convertible loan and its conversion is independent of the underlying note value. The Company recorded&#13;finance expenses in respect of the convertible component in the convertible loan in the excess amount of the convertible component&#13;fair value over the face loan amount. The conversion liability is then marked to market each reporting period with the resulting&#13;gains or losses shown in the statements of operations.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 1in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 1in; text-align: justify"&gt;The&#13;fair value of the convertible component was estimated by third party appraiser using the Black-Scholes option pricing model,&#13;to compute the fair value of the derivative and to mark to market the fair value of the derivative at each balance sheet&#13;date. The Company has estimated the fair value of such derivative at a value of $132 at the date of issuance and at a value&#13;of $26 as of December 31, 2020.

The terms of the Convertible Loan&#13;Agreements require repayment of the borrowed amount by the one-year anniversary of the Effective Time, unless, at Company's&#13;discretion, and subject to its compliance with any and all terms of the material terms of the Convertible Loan Agreements, the&#13;term of such loans is extended for an additional twelve (12) month period. The terms of the Convertible Loan Agreements also provide&#13;that the Company may repay any portion of the remaining outstanding loan amount, without penalty, provided, however, that the Company&#13;provides the specific lender with three business days' written notice prior to such repayment, during which time the lender&#13;may elect to convert any or all of the outstanding loan amount into shares of common stock of the Company. The Convertible Loan&#13;Agreements bear simple interest at a rate equal to 15% per annum, payable on the 15th day of each calendar month. On December 9,&#13;2020, the Company utilized its rights under the above agreement and extended the terms of the loans for additional twelve month.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; margin-top: 0pt; margin-bottom: 0pt"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 1in; text-align: justify"&gt;The lenders will have the option&#13;to convert the unpaid balance of their respective Convertible Loans into shares of Company's common stock based on the lower&#13;of (A) lowest effective price per share set in connection with any funds raised by the Company during the six (6) months following&#13;the Effective Time. "Effective price" per share means (i) if only shares of Company's common stock are sold in&#13;a transaction, the amount actually received in cash by the Company, and (ii) if shares of Company's common stock are sold&#13;in a transaction and, in connection therewith additional securities or rights are sold or otherwise issued, the amount actually&#13;received in cash by the Company, for the shares of Company's common stock and such additional rights upon their issuance,&#13;reduced by the aggregate fair market value of the additional rights (as determined using the Black-Scholes option pricing model&#13;or another method determined by the Company in good faith), in each case divided by the number of shares of Company's common&#13;stock issued in such transaction; (B) 80% of the lowest effective price per share set in connection with any funds raise by the&#13;Company at any time subsequent to six (6) months following the Effective Time until such time as the loans outstanding under all&#13;of the Convertible Loan Agreements are fully repaid or otherwise converted provided, however, that such price per share shall not&#13;be available in the event of an issuance of Alternative Securities to the lender); (C) a price per share reflecting a post-money&#13;valuation of the Company of $15million following the next investment in the Company following the Effective Time; or (D) the conversion&#13;price, as adjusted for a Dilutive Event, under the New Debentures. The conversion price is currently $0.374. As of March 30, 2021,&#13;the Convertible Loan Agreements have an aggregate outstanding principal balance of $835 as a result of the conversions of certain&#13;Convertible Loan Agreements (see note 15 below).&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 1in; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; margin-left: 1in; text-align: justify"&gt;In accordance with ASC 815-15-25,&#13;the conversion feature was considered an embedded derivative instrument, and is to be recorded at its fair value as its fair value&#13;can be separated from the convertible loan and its conversion is independent of the underlying note value. The Company recorded&#13;finance expenses in respect of the convertible component in the convertible loan in the excess amount of the convertible component&#13;fair value over the face loan amount.
