Giant Terahertz Birefringence in an Ultrathin Anisotropic Semimetal.

Manipulating the polarization of light at the nanoscale is key to the development of next-generation optoelectronic devices. This is typically done via waveplates using optically anisotropic crystals, with thicknesses on the order of the wavelength. Here, using a novel ultrafast electron-beam-based technique sensitive to transient near fields at THz frequencies, we observe a giant anisotropy in the linear optical response in the semimetal WTe and demonstrate that one can tune the THz polarization using a 50 nm thick film, acting as a broadband wave plate with thickness 3 orders of magnitude smaller than the wavelength.

Relabeling for Indoor Localization Using Stationary Beacons in Nursing Care Facilities.

In this study, we propose an augmentation method for machine learning based on relabeling data in caregiving and nursing staff indoor localization with Bluetooth Low Energy (BLE) technology. Indoor localization is used to monitor staff-to-patient assistance in caregiving and to gain insights into workload management. However, improving accuracy is challenging when there is a limited amount of data available for training.

Sondheimer oscillations as a probe of non-ohmic flow in WP crystals.

As conductors in electronic applications shrink, microscopic conduction processes lead to strong deviations from Ohm's law. Depending on the length scales of momentum conserving (l) and relaxing (l) electron scattering, and the device size (d), current flows may shift from ohmic to ballistic to hydrodynamic regimes. So far, an in situ methodology to obtain these parameters within a micro/nanodevice is critically lacking.

Integrating research into a molecular cloning course to address the evolving biotechnology landscape.

The rapid development of molecular biotechnology presents a curricular challenge for educators trying to provide students with relevant coursework. A comprehensive biology education should also include opportunities for students to develop intellectual and technical skills through authentic research experiences. Integrating relevant and interesting research projects into their classes, however, can be a challenging task for instructors.

The topology of electronic band structures.

The study of topology as it relates to physical systems has rapidly accelerated during the past decade. Critical to the realization of new topological phases is an understanding of the materials that exhibit them and precise control of the materials chemistry. The convergence of new theoretical methods using symmetry indicators to identify topological material candidates and the synthesis of high-quality single crystals plays a key role, warranting discussion and context at an accessible level.

Axion-Field-Enabled Nonreciprocal Thermal Radiation in Weyl Semimetals.

Objects around us constantly emit and absorb thermal radiation. The emission and absorption processes are governed by two fundamental radiative properties: emissivity and absorptivity. For reciprocal systems, the emissivity and absorptivity are restricted to be equal by Kirchhoff's law of thermal radiation.

CE: Original Research: Understanding the Hospital Experience of Older Adults with Hearing Impairment.

Unlabelled: : Background: Older hospitalized adults with hearing impairment are vulnerable to adverse outcomes. These patients are at risk for being labeled confused, experiencing a loss of control, experiencing heightened fear and anxiety, and misunderstanding the plan of care.

Objective: This qualitative study sought to assess the hospital experience of older adults with hearing impairment in order to formulate suggestions for improving nursing care.

A comparison of performance on the Keitel Functional Test by persons with systemic sclerosis and rheumatoid arthritis.

Purpose: The purpose of this study is to compare lower extremity impairments in persons with systemic sclerosis, rheumatoid arthritis, and healthy controls.

Methods: The participants were a convenience sample of 64 persons with systemic sclerosis, 58 persons with rheumatoid arthritis, and 30 healthy controls. The Keitel Functional Test was used to assess lower extremity joint motion and strength.

Innervation of dystrophic muscle after muscle stem cell therapy.

Introduction: Duchenne muscular dystrophy (DMD) is caused by loss of the structural protein, dystrophin, resulting in muscle fragility. Muscle stem cell (MuSC) transplantation is a potential therapy for DMD. It is unknown whether donor-derived muscle fibers are structurally innervated.

Mineral accumulation in vegetative and reproductive tissues during seed development in Medicago truncatula.

Enhancing nutrient density in legume seeds is one of several strategies being explored to improve the nutritional quality of the food supply. In order to develop crop varieties with increased seed mineral concentration, a more detailed understanding of mineral translocation within the plant is required. By studying mineral accumulation in different organs within genetically diverse members of the same species, it may be possible to identify variable traits that modulate seed mineral concentration.

Reprogramming of mesenchymal stem cells by oncogenes.

Mesenchymal stem cells (MSCs) originate from embryonic mesoderm and give rise to the multiple lineages of connective tissues. Transformed MSCs develop into aggressive sarcomas, some of which are initiated by specific chromosomal translocations that generate fusion proteins with potent oncogenic properties. The sarcoma oncogenes typically prime MSCs through aberrant reprogramming.

Targeting the Wnt pathway in synovial sarcoma models.

Unlabelled: Synovial sarcoma is an aggressive soft-tissue malignancy of children and young adults, with no effective systemic therapies. Its specific oncogene, SYT-SSX (SS18-SSX), drives sarcoma initiation and development. The exact mechanism of SYT-SSX oncogenic function remains unknown.

Nursing home recruitment: trials, tribulations, and successes.

Many challenges are inherent when conducting research in the older adult population as well as in the nursing home environment. The safety and quality of care provided in nursing homes need further examination through research. The purpose of this paper is to discuss research issues and recruitment barriers experienced by a research team collecting data for a study assessing the education and learning needs of nursing home nurses in central Illinois and related resident outcomes.

Genome-wide recruitment to Polycomb-modified chromatin and activity regulation of the synovial sarcoma oncogene SYT-SSX2.

Background: SYT-SSX is the oncogene associated with synovial sarcoma (SS), a stem cell disease. SYT-SSX is thought to be responsible for sarcoma initiation and development. It interacts with components of Polycomb and SWI/SNF complexes, the two epigenetic controllers that maintain the heritable status of differentiation-specific genes in the stem/progenitor cell.

Cohesion and conflict: family influences on adolescent alcohol use in immigrant Latino families.

This study examines how cohesion and parent–child conflict relate to alcohol use among Mexican-heritage adolescents. The sample consists of 120 adolescents (14 to 18 years) participants from the Southwest sub-sample of the Latino Acculturation and Health Project. Lifetime and recent alcohol use and binge drinking were tested.

The synovial sarcoma-associated SYT-SSX2 oncogene antagonizes the polycomb complex protein Bmi1.

This study demonstrates deregulation of polycomb activity by the synovial sarcoma-associated SYT-SSX2 oncogene, also known as SS18-SSX2. Synovial sarcoma is a soft tissue cancer associated with a recurrent t(X:18) translocation event that generates one of two fusion proteins, SYT-SSX1 or SYT-SSX2. The role of the translocation products in this disease is poorly understood.

Growth modelling indicates hurricanes and severe storms are linked to low coral recruitment in the Caribbean.

This study set out to test the hypothesis that hurricanes and tropical storms limit the recruitment and subsequent survival of massive non-branching corals on the barrier reef off the coast of Belize in the Gulf of Honduras. Overall, the surface areas of 523 individual coral specimens were measured, and recruitment dates were then modelled. There was no significant difference in coral cover or coral biodiversity between any of the sites studied (p > 0.

The synovial sarcoma SYT-SSX2 oncogene remodels the cytoskeleton through activation of the ephrin pathway.

Synovial sarcoma is a soft tissue cancer associated with a recurrent t(X:18) translocation that generates one of two fusion proteins, SYT-SSX1 or SYT-SSX2. In this study, we demonstrate that SYT-SSX2 is a unique oncogene. Rather than confer enhanced proliferation on its target cells, SYT-SSX2 instead causes a profound alteration of their architecture.
