We present constraints on low-mass dark matter electron scattering and absorption interactions using a SuperCDMS high-voltage eV-resolution (HVeV) detector. Data were taken underground in the NEXUS facility located at Fermilab with an overburden of 225 meters of water equivalent. The experiment benefits from the minimizing of luminescence from the printed circuit boards in the detector holder used in all previous HVeV studies. A blind analysis of 6.1 g·days of exposure produces exclusion limits for dark matter-electron scattering cross sections for masses as low as 1 MeV/c², as well as on the photon-dark photon mixing parameter and the coupling …

Exploring Enacted Active Learning Practices In Postsecondary Chemistry Lecture And Laboratory Courses, Kendall M. Zammit

USF Tampa Graduate Theses and Dissertations

The work in this thesis begins to explore the enacted active learning practices in postsecondary chemistry lecture and laboratory courses. Chapter 1 explores the level of inquiry in postsecondary laboratories. Chapter 2 explores instructional and assessment practices at two-year institutions.

Chemistry postsecondary laboratories offer a unique opportunity to engage students in inquiry-based instruction. Inquiry-based instruction was categorized by the asking faculty members at four-institutions about six characteristics of laboratory design: choosing a problem, background research, designing procedures, analyzing data, communicating results, and interpreting results. As students have the freedom to make decisions on more characteristics of inquiry learning, the closer …

Mom Is Developing Too: Preliminary Evidence For The Reciprocal Effects Of Infant Sensory Reactivity And Maternal Behavior, Emily C. Sweiss, Vincent Berardi, Elysia Poggi Davis, Curt A. Sandman, Laura M. Glynn

Psychology Faculty Articles and Research

Caregiver sensitivity to infant cues is well-established as a predictor of child development. Infants also actively influence their social environment, especially their caregivers, even from their earliest days. Sensory reactivity, characterized as hypo- (under) and hyper- (over) responding to environmental stimuli, is one domain of development that is likely to influence caregiver-infant interaction, due to its role in regulating emotions and responses to both physical and social stimuli. Although sensory reactivity could be an important target for improving caregiver-child interaction, the longitudinal, reciprocal relations between infant sensory reactivity and caregiver behaviors are currently unknown. In the present proof-of-concept study, we …

A Solution To The Tension Of Burning On Neutron Stars And Nuclear Physics, Yuri Cavecchi, D. K. Galloway, A. Heger, P. Santillán-Ortega, M. Nava-Callejas, F. M. Vincentelli, Liliana E. Rivera Sandoval, A. Goodwin, Z. Johnston

Physics & Astronomy Faculty Publications

When neutron stars accrete matter from a companion star, this matter forms a disk around them and eventually falls on their surface. Here, the fuel can ignite into bright flashes called Type I bursts. Theoretical calculations based on state-of-the-art nuclear reactions are able to explain many features of the bursts. However, models predict that the bursts should cease at high accretion rates, whereas in many sources they disappear at much lower rates. Moreover, their recurrence times also show strong discrepancies with predictions. Although various solutions have been proposed, none can account for all the observational constraints. Here, we describe a …

Osimertinib Activates A Tgf-Β2-Dependent Secretory Program That Drives Lung Adenocarcinoma Progression, Madhurima Ghosh, Chao Wu, Abhishek Kumar, Monique Nilsson, John V Heymach, Weina Zhao, Jiang Yu, Xin Liu, Na Ding, Shike Wang, Guan-Yu Xiao, Angelo Chen, Kate Grimley, William K Russell, Chad J Creighton, Xiaochao Tan, Jonathan M Kurie

Faculty, Staff and Student Publications

EGFR-mutant lung adenocarcinomas (LUADs) that are vulnerable to the EGFR antagonist osimertinib (Osi) eventually relapse, owing in part to the emergence of drug-tolerant persister (DTP) cells that arise through epigenetic mechanisms. Intratumoral DTP cells can herald a worse clinical outcome, but the way in which DTP cells influence LUAD progression remains unclear. Osi-resistant (OR) cells exhibit typical DTP cell features, including a propensity to undergo senescence and epithelial-mesenchymal transition (EMT), which can activate heightened secretory states. Therefore, we postulated that OR cells influence LUAD progression through paracrine mechanisms. To test this hypothesis, we utilized congenic pairs of EGFR-mutant LUAD cell …

Qualitatively Assessing Trade-Offs And Co-Benefits At Local Scales When Considering Carbon Outcomes Among Other Management Goals, Adrienne B. Keller, Ann L. Calhoun, Stephen D. Handler, Maria K. Janowiak, Caitlin E. Littlefield, Brian Miner

Michigan Tech Publications

Natural and working lands are often touted as natural climate solutions due to their ability to take up and store carbon, and land managers are increasingly tasked with considering how management actions impact carbon outcomes alongside other management goals. As a result, there is a need to assess how management actions may drive trade-offs and co-benefits between multiple management goals. However, quantitative analysis of trade-offs is not feasible for many local-scale management projects. We used a case study in an oak savanna in south-eastern Wisconsin, U.S.A. to develop and test a framework for qualitatively analysing local-scale trade-offs. Our framework is …

The Advantages Of Saudi Arabia’S Fixed Exchange Rate Regime For Inflation Control: An Econometric And Empirical Analysis, Rodrigo Bochner

Arab Economic and Business Journal

Since 1986, Saudi, has maintained a fixed exchange rate, pegging the Saudi Riyal (SAR) to dollar at SAR 3.75/USD. This stabilizing domestic prices, and promoting macroeconomic stability in an oil-dependent and economy exposed to volatile global commodity prices and international shocks. This paper provides a assessment of the fixed exchange rate’s advantages for inflation control. Leveraging a dataset spanning 1980–2025 and econometric tools— Ordinary Least Squares (OLS), Vector Error Correction Models (VECM), Autoregressive Distributed Lag (ARDL) techniques, and GARCH models—this study identifies the causal channels and measures the peg’s impact on inflation dynamics, with a review of literature, confirming that …

Transient T-Wave Inversions In A Pregnant Patient: Normal Variant Or Cause For Concern?, Muhammad Hammad Sharif, Madeeha Khaleeque, Muhammad Hassan Jan, Atif Ahmed, Aniket-Vijay Rao, Aditya Sanjeevi, Bipul Baibhav

Advances in Clinical Medical Research and Healthcare Delivery

Pregnancy can cause physiological changes in various body systems, including the cardiovascular system. This manifests as physiological changes in the electrocardiogram (EKG) in the form of sinus tachycardia, a change in the QRS axis, a short PR interval, the development of Q waves, a prolonged QT interval, T-wave inversions, and ST-segment depression. These changes are typically benign and reflect the body's adaptation to pregnancy. Physiological T-wave inversions can occur during pregnancy because of an increased workload on the heart due to expanding blood volume. It is important to identify these physiological EKG changes to avoid unnecessary invasive cardiac work-up and …

Prompt Thyroid Hormone Replacement Reversing Severe Bradycardia & Syncope, Cassie R. Girardin, George Vega, Rohail Baig

Advances in Clinical Medical Research and Healthcare Delivery

Thyroid disease, particularly hypothyroidism, can significantly affect the cardiovascular system, leading to structural, functional, and conduction abnormalities. Hypothyroidism decreases inotropy and chronotropy and may cause bradycardia or conduction defects. Although these changes are typically reversible with thyroid hormone replacement, severe cases may necessitate pacemaker placement. This case describes an 82-year-old female with hypothyroidism, atrial fibrillation, and left bundle branch block (LBBB) who presented with recurrent syncope due to hypothyroidism-induced bradycardia with sinus pauses. Her symptoms resolved with thyroid hormone optimization, highlighting the importance of prompt recognition and treatment of hypothyroidism-related cardiac manifestations to prevent unnecessary pacemaker implantation.
