Seismic imaging in 3-D holds great potential for improving our understanding of ice sheet structure and dynamics. Conducting 3-D imaging in remote areas is simplified by using lightweight and logistically straightforward sources. We report results from controlled seismic source tests carried out near the West Antarctic Ice Sheet Divide investigating the characteristics of two types of surface seismic sources, Poulter shots and detonating cord, for use in both 2-D and 3-D seismic surveys on glaciers. Both source types produced strong basal P-wave and S-wave reflections and multiples recorded in three components. The Poulter shots had a higher amplitude for low frequencies (<10 Hz) and comparable amplitude at high frequencies (>50 Hz) relative to the detonating cord. Amplitudes, frequencies, speed of source set-up, and cost all suggested Poulter shots to be the preferred surface source compared to detonating cord for future 2-D and 3-D seismic surveys on glaciers.

OBJECTIVES/GOALS: The goal of this study is to develop a multi-centered Translational Studio model that can help in the development of quality translational studies using resources from four different institutional partners (University of Texas Medical Branch, Texas Southern University, University of Houston Clear Lake and Houston Methodist). METHODS/STUDY POPULATION: We conducted two rounds of four Futures Workshops for a total participation of 28 stakeholders from four different partners. Future Workshops were used to critique, envision, and articulate novel “futures” that can be achieved at least partly through design practices (Muller, 2002). In the first round of workshops, we asked participants about their institutions’ strengths, weaknesses, resources and investigator needs regarding the Studio. In the second round we asked about different studio models, pros and cons of each model and guiding principles for a studio. Alongside a pragmatic content analysis, multi-stage deductive and inductive qualitative analyses were used to understand people’s views on the future of a multi-institutional Clinical Trials Studio. RESULTS/ANTICIPATED RESULTS: The first-round workshops’ analysis described peoples’ goals for what the studio should be. The future desired studio was described as guide, matchmaker, initiator and advocate. The second-round workshops’ analysis discussed the pros and cons of a variety of possible models including, centralized, decentralized, and topic-specific (and allowed other suggestions) while also describing principles for the guidance of a studio. Here the analysis showed people wanted certain characteristics for the studio (i.e. effective, efficient, locally-responsive, consistent, etc.). They also prescribed four principles that a studio should be guided by: non-hierarchical partnership, user-centeredness, respect/collegiality, and sharing. DISCUSSION/SIGNIFICANCE: The future workshops were useful in developing a shared multi-institutional Clinical Trials Studio model that is planned to be deployed in 2025. Participants valued a studio that was both directly supportive to participants and played a role in creating or advocating for institutional resources and policy for research.

OBJECTIVES/GOALS: The inclusion of underrepresented racial and ethnic groups (URGs) in clinical research is critical for ethical and scientific reasons. This initiative aimed to assess the perspectives, barriers, needs, and recommendations encountered by research teams when enrolling and retaining URGs in clinical research. METHODS/STUDY POPULATION: An anonymous, web-based survey comprised of quantitative and qualitative questions was administered to individuals involved in clinical research at an academic medical center. The survey assessed three main domains: 1. Research teams' perceptions and experiences with enrolling URGs in clinical research, 2. Factors that discourage URGs from participating in clinical research, and 3. Research teams’ overall willingness to support URG enrollment. Demographics were also collected. The survey was reviewed by experts in clinical research, research ethics, and diversity, equity, inclusion, and accessibility (DEIA). The assessment was piloted among research professionals and edits were made accordingly prior to official dissemination. Data were analyzed using descriptive statistics. RESULTS/ANTICIPATED RESULTS: There was a total of 63 responses. A majority of respondents have more success enrolling patients whose primary language is the same as their own and that time arranging for an interpreter has negatively impacted enrollment efforts. Approximately half of the respondents believe that the race and/or ethnicity of the potential study participant influences enrollment success. Factors discouraging URGs from participating in clinical research include unavailability for follow-up visits due to transportation issues, distrust in doctors and/or researchers, fear of unknown side effects, and unavailability of medical interpreters. Respondents report that they are not discouraged from enrolling URGs and would utilize resources related to encouraging the inclusion of URGs DISCUSSION/SIGNIFICANCE: Language appears more influential than ethnicity or race when it comes to enrolling and retaining URGs. Additionally, it appears that enrolling is a bigger challenge than retaining. Major themes that emerge with respect to retaining enrolled participants include the inability to attend follow-up visits and the lack of incentives/compensation.

To investigate the symptoms of SARS-CoV-2 infection, their dynamics and their discriminatory power for the disease using longitudinally, prospectively collected information reported at the time of their occurrence. We have analysed data from a large phase 3 clinical UK COVID-19 vaccine trial. The alpha variant was the predominant strain. Participants were assessed for SARS-CoV-2 infection via nasal/throat PCR at recruitment, vaccination appointments, and when symptomatic. Statistical techniques were implemented to infer estimates representative of the UK population, accounting for multiple symptomatic episodes associated with one individual. An optimal diagnostic model for SARS-CoV-2 infection was derived. The 4-month prevalence of SARS-CoV-2 was 2.1%; increasing to 19.4% (16.0%–22.7%) in participants reporting loss of appetite and 31.9% (27.1%–36.8%) in those with anosmia/ageusia. The model identified anosmia and/or ageusia, fever, congestion, and cough to be significantly associated with SARS-CoV-2 infection. Symptoms’ dynamics were vastly different in the two groups; after a slow start peaking later and lasting longer in PCR+ participants, whilst exhibiting a consistent decline in PCR- participants, with, on average, fewer than 3 days of symptoms reported. Anosmia/ageusia peaked late in confirmed SARS-CoV-2 infection (day 12), indicating a low discrimination power for early disease diagnosis.

Data compilations expand the scope of research; however, data citation practice lags behind advances in data use. It remains uncommon for data users to credit data producers in professionally meaningful ways. In paleontology, databases like the Paleobiology Database (PBDB) enable assessment of patterns and processes spanning millions of years, up to global scale. The status quo for data citation creates an imbalance wherein publications drawing data from the PBDB receive significantly more citations (median: 4.3 ± 3.5 citations/year) than the publications producing the data (1.4 ± 1.3 citations/year). By accounting for data reuse where citations were neglected, the projected citation rate for data-provisioning publications approached parity (4.2 ± 2.2 citations/year) and the impact factor of paleontological journals (n = 55) increased by an average of 13.4% (maximum increase = 57.8%) in 2019. Without rebalancing the distribution of scientific credit, emerging “big data” research in paleontology—and science in general—is at risk of undercutting itself through a systematic devaluation of the work that is foundational to the discipline.

In another tumultuous term of the United States Supreme Court in 2022-2023 a series of critical cases implicate instant and forthcoming changes in multiple fronts that collectively shift the national public health law and policy environment.
