Thanks, Jim, and good afternoon again everyone. At March 31, 2018, we had a cash balance of approximately $7 million. Our consolidated operating costs and expenses were approximately $5 million for the fiscal year ended March 31, 2018 compared to $6.5 million in the fiscal year ended March 31, 2017, a decrease of $1.5 million. The $1.5 million decrease was due to reductions in payroll and related expenses of approximately $844,000, and professional fees of approximately $608,000, and in general and administrative or G&A expense of approximately $57,000. The $844,000 decrease in payroll and related expenses was principally driven by $926,000 decrease in our non-cash stock-based compensation, which was partially offset by an $81,000 increase in cash, payroll and related expenses, and the headcount additions in our scientific staff. The $608,000 decrease in our professional fees was due to reductions in our non-DARPA related professional fees of $546,000, and our DARPA related professional fees of $39,000, and in Exosome Sciences’; professional fees of $24,000. The primary factors in $546,000 decrease in our non-DARPA related professional fees were; $224,000 reduction in legal fees due to a reduction in registration statement advance enacting activity in fiscal year '18 compared to fiscal year '17; a $146,000 reduction in clinical trial expense due to the conclusion of our clinical trial; and $114,000 reduction in business development expense. The $57,000 decrease in G&A expenses primarily arose from reductions in the G&A expenses and our DARPA related activities of $102,000; and in the G&A expenses at Exosome Sciences; of $30,000, which were partially offset by increases in our non-DARPA related activities of $75,000. We had other expense of approximately $869,000 for fiscal 2018 compared to other expense of approximately $1.2 million in fiscal 2017. During fiscal 2018, we recorded $149,625 in revenues under our contract with the National Cancer Institute, while during fiscal 2017 year recorded $392,000 in revenue from our government contract with DARPA. Overall, the net loss was approximately $5.7 million or $0.46 per share for fiscal 2018 compared to a net loss of approximately $7.3 million, or $0.94 a share for fiscal 2017. We put out these earnings and related commentary in a press release earlier this afternoon. That release included the balance sheet for March 31, 2018 and the statements of operations for the fiscal years ended March 31, 2018 and 2017. We will file our Form 10-K annual report following this call. And now, Jim Grossman, will be happy to take any questions that you may have. Operator, please open the call for questions.
