Development Of A Digital Electronic Framework To Manage High Power Systems In Small Satellite Missions, Mariel Serra, Rami Kandela, Bryan Johnston-Lemke, Robert E. Zee

Small Satellite Conference

• As small spacecraft payloads increase in complexity, they introduce the need for higher capacity and reliable power systems.
• The use of radiation tested automotive-grade components offer low-costs, however these parts are less suited to increased power demands, exhibiting signs of on-orbit latch-up.
• A re-design of a Modular Power System’s digital framework is proposed to support more spacecraft loads with minimal computational stress on the electronic processing units.

Distributed Avionics As A Foundational Architecture For Cubesat Constellations And Swarms, Aaron S. Swagei, Ali Guarneros-Luna

Small Satellite Conference

Motivation

CubeSat constellations and swarms require spacecraft that can tolerate subsystem faults without relying exclusively on a single centralized flight computer. Distributing sensing, control, and fault-management authority can improve containment and enable graceful degradation.

Objective

Develop and experimentally evaluate a distributed CubeSat avionics architecture in which subsystem nodes retain local fault-management authority while an F´-based OBC provides mission-level coordination.

The FlatSat is used as a representative spacecraft-level building block for future constellation and swarm architectures.

Integrated Optical/Body-Dynamics Simulations For Pointing, Acquisition And Tracking For The Pulse-A Mission, Juan Ignacio Prieto Asbun, Elizabeth Rosario, Jiayang Xu, Catherine Todd, Robert Pitu, Tian Zhong

Small Satellite Conference

PULSE-A is the University of Chicago’s student-led 3U CubeSat mission to demonstrate a space-to-ground optical downlink at a data rate of 1 to 10 Mbps using circular polarization shift keying (CPolSK).

To avoid costly and ineffective hardware-in-the-loop simulations, we instead present software-in-the-loop simulations designed to qualify our optical and PAT systems. This allows for simulations of the coupled optical systems that include closed-loop corrections and body pointing errors.

Understanding Primary Level Learner Progression In Scotland: Insights From Scottish Online Formative Assessments (Sofa) Data From The Highland Local Authority, Alexander Towne, Sladana Krstic

Assessment and Reporting

This report presents findings from more than 30,000 Scottish Online Formative Assessment (SOFA) assessments completed across one Scottish local authority during the 2024-2025 academic year. It demonstrates how SOFA can be used to monitor learning progression across numeracy, reading and writing, identify attainment gaps between learner groups, and provide detailed diagnostic evidence to support classroom practice, school improvement and local authority panning. Although based on a single local authority, the study illustrates how curriculum-aligned formative assessment can complement national assessment evidence by providing richer insight into learner development.

Trade Measures—Relationships And Implications, Peijie Wang, Zhiyuan Liu

Plymouth Business School

Various value-added trade measures have been developed to address the concern in the growing volume of trade in intermediates that are double counted when crossing international borders more than once. This paper raises a query and makes an inquiry into the query. How trade figures in these measures would look like if comparisons are made in net terms and in the context of trading with the rest of the world, given that some double counted elements offset themselves in a series of crossing border processes in opposite traffic? Examined among them in this study are domestic value added in gross …

Perfect Storm Impeding Strategic Leadership Decision-Making At Uc Berkeley, John Kraft, Arthur Kraft, Hank Adler

Business Faculty Articles and Research

Exogenous events have disrupted higher education and impacted the decision-making skills of university presidents. While all university presidents are affected, the problem is most acute at the thirty-six AAU members of the power four conferences. The exogenous events were the precipitous cancellation of federal research grants, the on again and off again restrictions on both new and current foreign students studying at US universities, the proposed 15% limit on indirect costs, the tax on university endowments, the changes in student loan programs, the annual $20.5 million NIL revenue sharing settlement for Division I (DI) athletes, and their share of the …

Beyond Better Conditions: Seaweed Farming And The Number Of Sentient Animals In Aquaculture, Shrilaxmi Patil, Matthew Unerman, Wasseem Emam

Animal Sentience

Oldfield & Bonano (2024) (O&B) document how far  fish welfare research lags behind welfare research in other animals. We share O&B’s feelings-based concept of welfare and agree that aquaculture seeded this field; but research volume has not scaled with animal numbers: Welfare attention per farmed fish or decapod remains negligible. Along the lines of preceding commentaries (Maia 2024, Mather 2024), we treat farmed aquatic animals as individuals rather than tonnage. We then raise a point so far absent from the commentary on O&B so far: reducing the number of sentient animals entering intensive systems. Coastal seaweed farming, which cultivates non-sentient …

Temperature Predictions With Zncuins/Zns Quantum Dots, Reu/Fri Program Physics And Astronomy, Amber Banks

Student Works

For hundreds of years, humans have built thermometers based on the principles of thermal expansion and contraction. In the modern world, there is a need to scale down our thermometers to monitor cellular reactions, both within the human body and within artificial organ chips. Lewis et al. (2020) introduces a nanoscale thermometer based on the thermal expansion of CdTe quantum dots. When ex panded, these dots exhibit systematic changes in photoluminescence (PL) which are recognized by a neural network as an increase in temperature. Our research builds upon the framework of Lewis et al. (2020), testing its feasibility with ZnCuInS/ZnS …

The Experience Of Wellness And Self-Care For Graduating Bsn Students, Jenny Pappas, Terri A. Clark, Tasha Ruffin, Deborah Ellison, Adrienne Wilk, Debra Rose Wilson

Journal of Social, Behavioral, and Health Sciences

The aim of this study was to explore how graduating prelicensure bachelor of science in nursing (BSN) students experience self-care and wellness, with the goal of informing future curriculum development. Nursing students face significant academic, emotional, and sociocultural pressures that heighten vulnerability to burnout. Despite widespread agreement that self-care is a professional expectation, little is known about the students’ experience within demanding programs. Guided by Orem et al.’s (2001) self-care deficit theory, a qualitative study using interpretive hermeneutic phenomenology was used to examine lived experiences of self-care and wellness. Sixteen graduating BSN students participated in in-depth, semistructured interviews. Interviews were …

Cognitive Warfare And The Brain-As-Battlespace: Neuroscience, Artificial Intelligence, And The Emerging Domain Of Neurostrategic Competition, James Giordano, Robert Schmidle

Strategic Insights

The human brain is becoming a consequential arena of strategic competition. This commentary looks at how cognitive warfare draws on the neural processes underlying perception, emotion, trust, identity, judgment, and decision-making to influence individual and collective behavior. It describes how existing beliefs, biases, social affiliations, and information environments shape the way people interpret and respond to competing narratives, making natural cognitive processes potential targets for exploitation. Dr. Giordano and Dr. Schmidle trace how advances in neuroscience, artificial intelligence, big-data analytics, neurotechnology, and behavioral modeling are expanding the ability to assess and potentially influence cognition. Particular attention is given to population …

New Frontiers In Diagnosing Equine Lameness, Hyrum Hoopes, Karl Hoopes

All Current Publications

Lameness is one of the most common and expensive health problems seen in horses. Modern technology allows veterinarians to look beneath the surface. Tools such as artificial intelligence (AI), computed tomography (CT), magnetic resonance imaging (MRI), digital radiography (X-rays), nuclear scintigraphy, ultrasound, and positron emission tomography (PET) give clearer, more detailed pictures of what’s happening inside the horse’s leg. Each technology offers different advantages, from identifying uneven movement to revealing hidden damage within bones, joints, or soft tissues. When combined with veterinary visual evaluation, they help pinpoint the cause of lameness faster and more accurately than ever before.
