Understanding Current Signals Induced by Drifting Electrons

Consider an electron drifting in a gas toward a collection electrode. A common misconception is that the electron produces a detectable signal only upon arrival at the electrode. In fact, the situation is quite the opposite. The electron induces a detectable current in the electrode as soon as it starts moving through the gas. This induced current vanishes when the electron arrives at the plate. To illustrate this phenomenon experimentally, we use a gas-filled parallel plate ionization chamber and a collimated $^{241}$Am alpha source, which produces a track of a fixed number of ionization electrons at a constant distance from the collection electrode. We find that the detected signal from the ionization chamber grows with the electron drift distance, as predicted by the model of charge induction, and in conflict with the idea that electrons are detectable upon arrival at the collection plate.Comment: 21 pages, 12 figure

Occupational Therapy in the Intensive Care Unit

In recent years, the number of inpatient cardiovascular surgeries has significantly increased in hospitals around America. Occupational therapists in the intensive care unit (ICU) at Mills-Peninsula Medical Center (Burlingame, California) lack a standard protocol for addressing physical, cognitive, and psychosocial factors in patients post cardiac surgery. Furthermore, individuals’ experience and clinical reasoning frequently guides interventions rather than current evidence. The American Occupational Therapy Association’s Centennial Vision encourages occupational therapists to pursue science-driven practices and provide evidence-based interventions. In response to this Vision, an evidence-based clinical pathway was developed for the occupational therapists at Mills-Peninsula Medical Center. The clinical pathway facilitates patients’ return to their highest level of function during post cardiac surgery rehabilitation. The proposed clinical pathway includes physical recovery, early detection of cognitive impairment, and psychosocial health for patients post cardiac surgery. The final clinical pathway was compiled into a clinical manual, entitled Clinical Pathway for Post Cardiac Surgery – Progression of Occupational Therapy in Intensive Care Unit, and adapted into a pocket guide

Occupational Therapy in the Intensive Care Unit

In recent years, the number of inpatient cardiovascular surgeries has significantly increased in hospitals around America. Occupational therapists in the intensive care unit (ICU) at Mills-Peninsula Medical Center (Burlingame, California) currently lack a standard protocol for addressing physical, cognitive, and psychosocial factors in patients post cardiac surgery. Furthermore, interventions are frequently guided by professional experience and clinical reasoning instead of current evidence. The American Occupational Therapy Association’s Centennial Vision encourages occupational therapists to pursue science-driven practices and provide evidence-based interventions. In response to this vision, an extensive review of current literature was conducted and applied to develop an evidence-based clinical pathway for the occupational therapists at Mills-Peninsula Medical Center. The proposed clinical pathway includes intervention guidelines for physical recovery, early detection of cognitive impairment, and psychosocial health for patients post cardiac surgery recovering in the ICU. The clinical pathway would establish a standard of care and facilitate patients’ return to their highest level of function during post-cardiac surgery rehabilitation.https://scholar.dominican.edu/ug-student-posters/1032/thumbnail.jp

Using Integrated Data to Understand Early Childhood Risks and Access to Quality Early Childhood Education

The Use of Integrated Data to Inform Quality Pre-K Expansion in Philadelphia

This research brief describes how integrated administrative data from the City of Philadelphia\u27s CARES data system were used to inform the expansion of pre-k services in the City of Philadelphia. It provides a model for other states and municipalities seeking to use integrated data to inform policy-making, particularly for young children and their families.https://repository.upenn.edu/pennchild_briefs/1000/thumbnail.jp

Chat2Map: Efficient Scene Mapping from Multi-Ego Conversations

Can conversational videos captured from multiple egocentric viewpoints reveal the map of a scene in a cost-efficient way? We seek to answer this question by proposing a new problem: efficiently building the map of a previously unseen 3D environment by exploiting shared information in the egocentric audio-visual observations of participants in a natural conversation. Our hypothesis is that as multiple people ("egos") move in a scene and talk among themselves, they receive rich audio-visual cues that can help uncover the unseen areas of the scene. Given the high cost of continuously processing egocentric visual streams, we further explore how to actively coordinate the sampling of visual information, so as to minimize redundancy and reduce power use. To that end, we present an audio-visual deep reinforcement learning approach that works with our shared scene mapper to selectively turn on the camera to efficiently chart out the space. We evaluate the approach using a state-of-the-art audio-visual simulator for 3D scenes as well as real-world video. Our model outperforms previous state-of-the-art mapping methods, and achieves an excellent cost-accuracy tradeoff.

"The Visual in Black Life": Perspectives in Black Memory Work

In the words of the late scholar, critic, and artist, bell hooks, “though rarely articulated as such, the camera became in black life a political instrument, a way to resist misrepresentation as well as a means by which alternative images could be produced.” Black librarianship and memory work has been integral to preserving the evidence of this resistance, the blueprint of an alternative future through ethical and culturally-informed collection, description, and engagement. Even in the context of today's digital landscape, Black stewardship continues to ensure the preservation of a people's history into the future, even in spaces yet to be imagined. Centering the work of stewarding collections of Black visual culture and Black artist archives, this roundtable examines some of the ways that this work has transformed and translated over different times and spaces. Attendees will learn from varying perspectives of Black visual culture stewardship through the voices of four Black women memory workers contributing to critical archival, curatorial, artist documentation, and publishing work. From stewarding private artists' collections and documenting Black women artists to photo curating for book projects and exhibitions, the presenters will offer considerations and strategies for caring for the rich history that is Black visual culture

Upper Extremity Superficial Vein Thromboses Presenting as Acute Neck Pain in a Young and Healthy Male: A Case Report

# Background and Purpose Neck pain in the United States is pervasive and contributes to disability. While the majority of neck pain in young and healthy individuals is neuromusculoskeletal in nature, screening for red flags is necessary for ruling-out serious medical pathologies. The purpose of this case report is to describe a young and healthy male subject with a primary complaint of acute neck pain with multiple underlying upper extremity superficial vein thromboses (UESVTs). # Case Description The subject was a 27-year-old male active-duty Soldier referred to physical therapy by his primary care provider (PCP) for acute left-sided neck pain. Prior to physical therapy, the subject had been treated with cyclobenzaprine, oxycodone-acetaminophen, trigger point injection and had undergone a D-dimer to rule out a potential thrombus due to air travel and lower extremity immobilization. # Outcomes The subject underwent a D-dimer, Doppler ultrasound, pharmacological treatment of Rivaroxaban, and was referred to hematology/oncology to rule out systemic causes of SVTs. Evidence of subtle increases in blood pressure over the course of three months, a positive D-dimer, and symptoms incongruent with clinical presentation contributed to referral to a hematology/oncology specialist and a diagnosis of multiple UESVTs. The subject was able to return to his previous level of activity by six months and remained free of SVTs at two-year follow-up. # Discussion UESVT events are rare and can be challenging to identify. This case report describes a unique presentation of acute neck pain caused by underlying UESVTs in an otherwise healthy and active young male. # Level of Evidence Level
