Educational Opportunity Fund Program and Community College Student Retention

The EOF program is a state funded student support services program designed to provide access and financial support to disadvantaged students, and to improve student success as measured by student retention and graduation rates. This research examined the effects of EOF program and other factors on first semester retention in a community college. . Three models were developed: baseline model (whole group), and two sub group models (EOF and comparable non-EOF). Logistic regression analysis revealed that participation in EOF was positively related to student retention at the end of the first semester. Gender, race/ethnicity, college placement test (reading and math), and first semester GPA were also statistically significant in the baseline model and comparable non-EOF model. Additionally, results indicate that, compared to the comparable non EOF group, EOF students tended to have reduced gaps in retention by gender or race/ethnicity. The results of this study provide empirical support that institutional administrators and state policy makers should increase the amount of funding allocated for EOF, to ultimately increase the number of students who can participate in the program. Future research should focus on replicating this study at multiple community colleges and four-year institutions, and a program evaluation for the EOF program could offer additional insight into first semester student retention

Performance of a modular ton-scale pixel-readout liquid argon time projection chamber

The Module-0 Demonstrator is a single-phase 600 kg liquid argon time projection chamber operated as a prototype for the DUNE liquid argon near detector. Based on the ArgonCube design concept, Module-0 features a novel 80k-channel pixelated charge readout and advanced high-coverage photon detection system. In this paper, we present an analysis of an eight-day data set consisting of 25 million cosmic ray events collected in the spring of 2021. We use this sample to demonstrate the imaging performance of the charge and light readout systems as well as the signal correlations between the two. We also report argon purity and detector uniformity measurements, and provide comparisons to detector simulations

Supernova Pointing Capabilities of DUNE

International audienceThe determination of the direction of a stellar core collapse via its neutrino emission is crucial for the identification of the progenitor for a multimessenger follow-up. A highly effective method of reconstructing supernova directions within the Deep Underground Neutrino Experiment (DUNE) is introduced. The supernova neutrino pointing resolution is studied by simulating and reconstructing electron-neutrino charged-current absorption on $^{40}$Ar and elastic scattering of neutrinos on electrons. Procedures to reconstruct individual interactions, including a newly developed technique called ``brems flipping'', as well as the burst direction from an ensemble of interactions are described. Performance of the burst direction reconstruction is evaluated for supernovae happening at a distance of 10 kpc for a specific supernova burst flux model. The pointing resolution is found to be 3.4 degrees at 68% coverage for a perfect interaction-channel classification and a fiducial mass of 40 kton, and 6.6 degrees for a 10 kton fiducial mass respectively. Assuming a 4% rate of charged-current interactions being misidentified as elastic scattering, DUNE's burst pointing resolution is found to be 4.3 degrees (8.7 degrees) at 68% coverage

First Measurement of the Total Inelastic Cross-Section of Positively-Charged Kaons on Argon at Energies Between 5.0 and 7.5 GeV

International audienceProtoDUNE Single-Phase (ProtoDUNE-SP) is a 770-ton liquid argon time projection chamber that operated in a hadron test beam at the CERN Neutrino Platform in 2018. We present a measurement of the total inelastic cross section of charged kaons on argon as a function of kaon energy using 6 and 7 GeV/$c$ beam momentum settings. The flux-weighted average of the extracted inelastic cross section at each beam momentum setting was measured to be 380$\pm$26 mbarns for the 6 GeV/$c$ setting and 379$\pm$35 mbarns for the 7 GeV/$c$ setting
