Thank you, Lori. I'm going to discuss some of the financial information that was contained in our press release for the fiscal first quarter ended September 30, 2019, that we released a short while ago. We anticipate that our Form 10-Q will be filed with the SEC on or around November 14. Revenue for the first quarter ended September 30, 2019 grew 48% to $2.315 million versus $1.56 million for the same period last year. As Lori mentioned earlier, the primary driver of revenue growth for the quarter was the company's core prostate brachytherapy business, which increased 51% versus the first quarter of 2019. First quarter revenue was comprised of 90% for prostate brachytherapy with the balance or 10% of revenue attributed to other brachytherapy primarily of sales to treat brain, gynecological, colorectal and other cancers. Gross profit as a percentage of revenues for the first quarter ended September 30, 2019 increased to a record 53.4% compared to 33.5% for the quarter ended September 30, 2018. The gross margin increase was primarily driven by higher sales and significantly lower isotope unit costs when compared to the prior year comparable period, continued leverage of the fixed cost components within cost of sales, and more efficient isotope usage. The lower isotope unit costs are related to our previously discussed change in our supply chain made at the end of calendar year 2018. First quarter gross profit dollars of $1.24 million increased 136% when compared to the same period last year. Total operating expenses consisting of research and development sales and marketing and general and administrative totaled $2.07 million or an increase of 1% compared with the first quarter of 2019 on revenue growth of 48%. Total R&D expense decreased 45% versus the comparable prior year quarter to $233,000. The decrease in total research and development expenses was primarily the result of a mutually agreed termination of a grant agreement, which resulted in a reversal of the accrual as well as the year-over-year decline in collaborative research expenses related to GammaTile therapy. Going forward, we would expect R&D expense to increase back to or above levels in prior recent quarters. We are currently holding discussions with institutions looking at the expanded use of Cesium-131. Sales and marketing expenses increased 26% versus the comparable prior year quarter to $815,000. The increase in sales and marketing expenses was driven primarily by increased headcount and incentive compensation related to the 48% increase in revenue as well as increased travel expenses largely due to a calendar shift of this year's ASTRO Conference to September, whereas 2018 conference was in October. G&A expenses of $1.1 million represented an increase of 13% versus $973,000 in the fiscal first quarter 2019. The year-over-year increase was driven primarily by increased headcount and incentive compensation related to the 48% year-over-year increase in revenue. Total operating expenses for the first quarter of 2020 included a change in estimate of asset retirement obligation as a result of a lease term extension during the first quarter of fiscal 2020, which decreased total operating expenses by $73,000. Excluding this one-time gain in the change in estimate, operating expenses were $2.15 million or an increase of 5% compared with the first quarter of 2019. IsoRay posted net loss of $816,000 for the first quarter ended September 30, 2019, a significant improvement compared to a net loss of $1.51 million for the quarter ended September 30, 2018. Excluding the one-time gain and change in estimate of the asset retirement obligation, IsoRay's net loss was $889,000 for the quarter ended September 30, 2019. The net loss per basic and diluted share was $0.01 versus the net loss of $0.02 for the quarter ended September 30, 2018. Basic and diluted share results are based on weighted average shares outstanding of approximately 67.4 million at fiscal first quarter 2020 versus 66.1 million for the prior year period. As of September 30, 2019 the company had cash, cash equivalents and certificates of deposit that totaled $4.58 million compared to $5.33 million at the end of fiscal 2019 ended June 30, 2019. The company has zero long-term debt. Shareholders' equity at the end of fiscal first quarter 2020 totaled $6.96 million versus $7.68 million at the end of fiscal 2019. I will now turn the call over to the operator to take questions from our analysts and institutional investors.
