Short-Term Promissory Notes and Unsecured Loan	NOTE 7 – Short-Term Promissory Notes and Unsecured Loan Short-Term Promissory Notes The Company issued short-term unsecured and interest-free promissory notes (the "Short-Term Notes") for aggregate gross proceeds of $253,000 in August 2017 which included free standing equity warrants. The Short-Term Notes were subsequently amended in November 2017 to extend the maturity date and increase the number of shares of Common Stock issuable upon exercise of the related warrants. The Short-Term Notes were also amended in March 2018 to become convertible, include new interest payment provisions and new conversion features and to provide for the issuance of a replacement warrant (the "Replacement Warrant") and an additional warrant (the "Additional Warrant") described more fully below. During the three and six months ended March 31, 2018, interest on the principal was $1,124. Effective July 2, 2018, the Company entered into debt conversion agreements with each Short-Term Note subscriber to (i) convert the outstanding principal and accrued and unpaid interest (the "Outstanding Balance") under the Short-Term Notes into shares of the Company's common stock based on the Outstanding Balance divided by $1.80 per share (the "Short-Term Note Conversion Shares"); (ii) cancel and extinguish the Short-Term Notes; and (iii) amend and restate the Replacement Warrants and Additional Warrants, as described more fully below, to make them immediately exercisable upon the conversion, at a per share exercise price equal to $1.80 per share. As consideration for the early conversion of the Short-Term Notes, the Company issued each subscriber a new warrant (the "Short-Term Note Payment Warrants"), exercisable for up to the number of shares of common stock equal to the number of Short-Term Note Conversion Shares received by such subscriber; at a per share exercise price of $1.80 per share. The Short-Term Note Payment Warrants became exercisable commencing on July 2, 2018, and expire on November 21, 2021. Prior to the debt conversion agreements, the November 2017 amendment resulted in a substantial modification to the original Short-Term Notes whereby additional warrant coverage was added and the maturity date of the Short-Term Notes was extended. The Company recorded the November 2017 Short-Term Note amendment under the provisions of extinguishment accounting. A loss on note extinguishments in the accompanying condensed consolidated statements of operations for the six months ended March 31, 2018 was recorded in the amount of $144,577, which represented the difference between the face value of the Short-Term Notes over the combined carrying values of the Short-Term Notes and warrants on the date of the amendment. The fair value increase of the Short-Term Notes and the warrants as amended over its adjusted carrying value at the time of the amendment was $117,280 which was recorded as additional paid-in capital. During the three and six months ended March 31, 2018, interest related to amortization of discounts associated with the separation of the equity warrants and issuance costs amounted to zero and $21,627, respectively. The March 2018 amendment also resulted in a substantial modification to the Short-Term Notes whereby additional conversion features and warrant coverage were added. The Company recorded the Short-Term Note amendment under the provisions of extinguishment accounting. A loss on Short-Term Notes extinguishment in the accompanying condensed consolidated statements of operations for the six months ended March 31, 2018 was recorded in the amount of $186,220, which represented the difference between the carrying value of the Short-Term Notes over the combined fair values of the Short-Term Notes, premium conversion derivative, Replacement Warrant and Additional Warrants on the date of the amendment. The fair value decrease of the Short-Term Notes (inclusive of principal and interest, non-bifurcated embedded conversion feature and the Additional Warrants) relative to its adjusted carrying value at the time of the amendment was $1,170 which was recorded as a reduction to additional paid-in capital on the accompanying condensed balance sheets. The March 2018 amendment of the Short-Term Notes contained a 125% conversion premium in the event that a Short Term Note Qualified Financing occurred at a price under $2.25 per common share. The Company determined that the redemption feature under the Short-Term Notes qualified as an embedded derivative and was reflected as a liability in the amount of $49,668 at the time of the March 2018 amendment with a corresponding offset to extinguishment loss described above. Subsequent to the amendment, the embedded derivative was accounted for separately on a fair market value basis. The Company recorded the fair value changes of the premium debt conversion derivative associated with the Short-Term Notes in the condensed consolidated statements of operations for an expense of $43 for the three and six months ended March 31, 2018. In addition, the March 2018 amendment provided for the issuance of Replacement Warrants that were deemed to be free-standing instruments and were accounted for as a liability given the variable number of shares issuable in connection with a possible change of control conversion event. The Company recorded an initial liability of $137,722 upon issuance of the Replacement Warrants with an offset to extinguishment loss as described above. The fair value changes of the warrant liability associated with the Short-Term Notes are recorded at each reporting date in the condensed consolidated statements of operations which amounted to a benefit of $(2,370) for the three and six months ended March 31, 2018. A Monte Carlo simulation model was used to estimate the aggregate fair value of the Replacement Warrants as of March 31, 2018. Input assumptions used were as follows: a risk-free interest rate of 2.45%; expected volatility of 50%; expected life of 3.64 years; and expected dividend yield of 0%. The underlying stock price used in the analysis was on a non-marketable basis and was according to the market approach, considering both the traded price and forward multiples from guideline public companies, using allocation and marketability-discount methodologies. As noted above, the Short-Term Notes were converted into shares of common stock and were not outstanding during the three and six month period ended March 31, 2019. Unsecured Loans In December 2018, the Company received gross proceeds from an unsecured loan represented by one promissory note in the amount of $100,000 from a stockholder owning over 5% of the Company's common stock. The loan is interest free and requires that the Company repay the principal in full on the earlier of the closing of an equity round of financing of the Company resulting in more than $5 million in gross proceeds or December 12, 2019. In November 2018, the Company received cash gross proceeds from unsecured loans represented by two promissory notes in the amounts of $45,000 and $100,000 from a stockholder owning or affiliated with stockholders owning over 5% of the Company's common stock. The loans are interest free and require that the Company repay the principal in full on the earlier of the closing of an equity round of financing of the Company resulting in more than $5 million in gross proceeds or November 14, 2019. In the second quarter of 2019, $100,000 of principal was repaid to one of the promissory note holders. On May 17, 2018, the Company received cash proceeds of $168,000 from unsecured loans, represented by two promissory notes from a stockholder owning or affiliated with stockholders owning over 5% of the Company's common stock. The loans are interest free and require that the Company repay the principal in full on the earlier to occur of (i) May 17, 2019 or (ii) the closing of an equity round of financing of the Company that raises more than $5 million in gross proceeds.
