Thanks, Sujal. Overall, we made solid progress against our core goals in 2023. Our major focus last year was on development activities, i.e., increasing scale, stability and reproducibility across our entire ecosystem, but especially our consumables. We additionally made significant progress in reducing the cost and complexity of producing our consumables. This progress goes hand-in-hand with advancing the reliability, quality and customer readiness of our instrument and software. Some examples of this progress include significantly increasing the development pace for our affinity reagents. This increase was a result of optimizing the yield and throughput of our reagent development pipeline. We also transitioned many of those new reagents into common experimental use. We advanced our fabrication and assembly processes for our nano pattern chip and flow cell. This refinement enabled both improvements in scale and reproducibility. We additionally qualified our external patterning and assembly partners. After refining our nano particle scaffolds, we more than 10x the throughput and scale of manufacturing for both our labeled probes and our nano particle scaffolds. 2023 also saw a continued focus on advancing our commercial instrument, especially the integration of the hardware, software and wetware elements, taking an instrument from concept to commercial readiness is complex and requires close coordination between teams across the company. I'm pleased with the progress I saw last year in this regard with the instrument becoming a true workhorse. The combination of advances in our consumable production scale, reliability and reproducibility, the increased stability of our multicycle assays and the expansion and available number of commercial form factor instruments enabled us to successfully perform substantially greater numbers of longer-cycle experiments in the past quarter than we did in the prior several years combined. That work continues to accelerate in 2024. The deluge of data from these more numerous and larger scale experiments also drove advances in the software and bioinformatics aspects of our platform. In particular, like with the instrument, we have switched over from prototype software tools to the integrated and automated pipelines that will be used by our customers. In the past, these analyses might take weeks of hands-on time to execute, and now analyses can be achieved with minutes of hands-on time. As we reported in Q2, the increasing experimental scale and assay robustness has enabled us to increase the set of model proteins that can be successfully decoded. We have diversified our models to include mixes of multiple proteins across a range of concentrations and are excited about further increasing the complexity of our model systems. These efforts are essential to the path towards verification and validation required for launch. Coming out of 2023 and into 2024, we remain focused on addressing the foundational elements required to launch our platform, ranging from how to mobilize single protein molecules on our nano pattern flow cell, how to detect diverse epitopes within proteins at single molecule resolution, the ability to run large-scale experiments involving a large number of probes across large numbers of cycles and an instrument ready to transition into broader use. In an ongoing demonstration of our commitment to transparency and openness, we continue to reach out to the broader proteomics community with the objective of sharing the scientific underpinnings of our platform. These conversations frequently lead to suggestions of exciting and creative applications of our platform that we had not previously envisioned. The next major opportunity for data sharing and application ideation comes in two weeks at the US HUPO conference in Portland, Oregon. I am incredibly excited by the opportunities we'll have at the event where we'll be publicly presenting on the following topics, additional progress on the experimental implementation of PrIsM, further detail on our multi-affinity Pro pipeline and on computational methods to estimate false discovery rate Overall, we continue to listen to the proteomics community, our future customers to ensure that we are sharing with them ongoing updates on our progress towards specific technical areas. One of the areas that I'm most excited about is the additional data we'll be sharing resulting from the targeted proteoform studies of Tau and EGFR that we've been pursuing in partnership with Genentech and Amgen. All the advances that we've made towards advancing our platform for broad scale studies have synergistically and simultaneously advanced our platform for targeted proteoform studies. We continue to hear from the community how important proteoforms, as defined by combinations of splice variants and post-translational modifications, ARC [ph] disease biology and the excitement about our platform is uniquely suited to measure the molecular heterogeneity of proteoforms at single molecule resolution. As Sujal mentioned earlier, we come into this year clear eye about what work remains to be done and confident that we have a solid foundational understanding of what is required to get our platform into the hands of users, where it can have a profound impact. With that, I'll turn the call back to Sujal.
