Thanks, Rob, and good morning, everyone. I'll start my comments today with a review of our first quarter results and then discuss our second quarter and full year 2024 outlook. Q1 revenue increased 11% to $5.6 million compared to $5 million in Q1 2023. During the first quarter, we placed three Growth Direct systems compared to three in the first quarter last year. We also completed three validations in the quarter compared to two in the first quarter last year. Product revenue, which is comprised of systems and consumables, increased 12% to $3.7 million in the quarter compared to $3.3 million in Q1 last year. The growth in product revenue was primarily driven by a record quarter in consumables as a result of continued growth in validated systems as well as several shipments made during Q1 that were originally expected in Q2. Service revenue increased 11% to $1.9 million in the first quarter compared to $1.7 million in Q1 last year. Service revenue growth was impacted in Q1 by some planned validation revenue that shifted into early Q2. The increase compared to the prior year quarter was primarily driven by a higher level of validation activity as well as higher revenue from service contracts due to the increase in the number of validated Growth Direct systems. First quarter recurring revenue, which consists of consumables and annual service contracts, increased 15% to $3.7 million, compared to $3.3 million in Q1 last year. Non-recurring revenue, which is comprised mainly of systems and validation revenue was $1.9 million in Q1, compared to $1.8 million in the prior year quarter. Turning to gross margins. Product margins were negative $1.5 million in Q1 compared to negative $1.7 million in the first quarter last year. As we expected and is typical for our business, Q1 product margin stepped down from Q4 2023 mainly due to lower system placements and revenue. Compared to Q1 last year, the improvement was attributable to continued benefits from actions we've taken to lower product costs and increased manufacturing efficiency. These benefits were partially offset by some customer site readiness delays, which shifted $0.2 million in high margin LIMS software revenue from Q1 into Q2 and unfavorable product mix due to the higher proportion of consumable revenue in Q1 this year. Service margins were slightly negative in the first quarter, largely due to non-recurring expenses. This compares to negative $0.1 million in the first quarter last year. On a combined basis, our first quarter gross margin was negative $1.5 million or negative 27% compared to negative $1.8 million or negative 36% in Q1 last year. We continue to expect our Q1 gross margins to be the lowest of the year. We then expect meaningful improvement as we work our way through the remaining quarters, as volumes and revenue increase and we continue to make progress on our initiatives focused on product cost reduction and manufacturing efficiency as well as service productivity. Continuing down the P&L, total operating expenses were $12.8 million in the first quarter, compared to $13.1 million in the prior year quarter, a reduction of approximately 3% versus the prior year period. R&D expenses were $3.8 million in Q1, an increase of 22% versus the prior year period, largely due to activities associated with the upcoming launch of Rapid Sterility. Sales and marketing expenses were $3.3 million and G&A expenses were $5.6 million in the first quarter, representing a combined 10% reduction versus the prior year quarter, as we tightly control spending in the business. Net loss was $13.3 million in Q1. This compares to a net loss of $13.9 million in Q1 last year. Net loss per share was $0.31 in Q1 compared to net loss per share of $0.32 in the prior year quarter. With respect to non-cash expenses and capital expenditures, depreciation and amortization expenses were $0.8 million, stock compensation expense was $1.1 million and capital expenditures were $0.6 million in the first quarter. We ended the first quarter with approximately $80 million of cash and investments on our balance sheet. I'll now turn to our Q2 and full year 2024 outlook. We continue to expect total revenue of at least $27 million for the full year 2024, which assumes that we will place at least 20 systems. This implies year-over-year revenue growth of at least 20%. This guidance continues to reflect some uncertainty related to the timing and scale of customer purchase decisions. For the second quarter, we expect total revenue of at least $6 million, which assumes at least four system placements. We then expect revenue and placements to increase sequentially in Q3 and peak in Q4, consistent with our typical annual cadence and the guidance we provided in March. Looking at consumables, we expect revenue to decrease sequentially in Q2 compared to Q1, due primarily for the timing of customer orders and shipments. We then expect consumable revenue to increase sequentially in Q3 and then again in Q4, as mortgage systems complete validation and enter routine use. With respect to service, we expect revenue to be between $2 million and $2.5 million each quarter over the balance of the year, with variability within this range primarily driven by the timing of validation activities. We are reaffirming our guidance of at least 16 validations in 2024, including at least four in the Q2. Turning to gross margins. We expect meaningful sequential improvement in the second quarter compared to the first quarter, but we still expect Q2 margins to be negative. Thereafter, we continue to expect positive gross margins in both Q3 and Q4 as well as for the full year. We expect product margins to improve each quarter, based on ongoing cost reduction and manufacturing efficiency initiatives as well as increasing volume, but remain negative. We expect double-digit positive service margins in each of the remaining three quarters of the year, based on higher revenue and improved productivity. Looking forward, we remain confident in our ability to meaningfully improve our gross margins in 2024 and beyond, as we continue to grow revenue, reduce product costs, drive higher manufacturing efficiency, control manufacturing overhead costs and increased service productivity. We continue to expect operating expenses to be in a range of $48 million to $52 million in 2024, with depreciation and amortization expense of approximately $3 million, stock compensation expense of approximately $5 million, CapEx of approximately $3 million and other income, which is comprised primarily of interest income of approximately $4 million. Finally, we continue to expect cash burn of roughly $40 million for the full year 2024. Looking out further, our goal is to reduce cash burn meaningfully over each of the next several years, as we drive towards profitability through a combination of revenue growth, margin improvement and management of our OpEx, CapEx and working capital. This supports our expectation that our existing cash and investments provide us with runway at least into the second half of 2026. That concludes my comments. At this point, we'll open the call up for questions. Operator?
