This exploratory study described the experiences of choice in physical activity contexts for adults with mobility impairments. The experiences of 3 female and 2 males with mobility impairments between 18 and 23 years of age were described using the interpretive phenomenological methods of individual interviews, written stories, and field notes. Thematic analysis revealed three themes: (a) inter...

PURPOSE We describe impairments after breast cancer and its treatment for African American (AA), non-Hispanic white and low-income breast cancer survivors (BCS) and whether physical therapy (PT) was utilized to address these impairments. METHODS BCS from the Southern Community Cohort Study (SCCS) were surveyed about self-reported BC treatment-related impairments (shoulder impairment, muscle w...

This article introduces a neural network-based signal processing framework for intelligent Reflecting surface-aided (IRS) wireless communications systems. By modeling radio frequency (RF) impairments inside the meta-atoms of IRS - including nonlinearity and memory effects) we present an approach that generalizes entire IRS-aided system as reservoir computing (RC) system, efficient recurrent net...

In this paper, the influence of physical layer impairments on fiber optic channels was evaluated using analytical modeling, and findings were verified through simulation results. Light propagation inside standard single mode (SSMF) is affected by both linear nonlinear effects, which must be taken into account in order to develop an appropriate channel model. The use optics implementation highca...

We propose and experimentally demonstrate a novel encryption scheme to enhance the physical layer security in broadcast passive optical networks (PONs). exploit, for first time, new dimension using non-orthogonality encryption. Different from conventional masking of data, proposed chaotic non-orthogonal matrix (CNOM) can also dynamically scramble number subcarriers an orthogonal frequency divis...

CONTEXT Muscle impairments associated with knee osteoarthritis (OA) are the primary underlying cause of functional limitations. Understanding the extent of muscle impairments, its relationship with physical function and disease progression, and the evidence behind exercise therapy that targets muscle impairments is crucial. EVIDENCE ACQUISITION An electronic search for relevant articles using...

People with visual impairments face a variety of obstacles in their daily lives. Recent work has identified specific physical privacy concerns of this population and explored how emerging technology, such as wearable devices, could help. In this study we investigated their physical safety and security concerns and behaviors by conducting interviews (N=19) with participants who have visual impai...
