Anthropogenic climate change will likely increase diarrhea rates for communities with inadequate water, sanitation or hygiene facilities including those with intermittent water supplies. Current approaches to study these impacts typically focus on the effect of temperature on all-cause diarrhea while excluding precipitation and diarrhea etiology while not providing actionable adaptation strategies. We develop a partially mechanistic, systems approach to estimate future diarrhea prevalence and design adaptation strategies...

The Laser Interferometer Gravitational-wave Observatory (LIGO) consists of two identical yet independent, widely separated, long-baseline gravitational-wave detectors. Each Advanced LIGO detector consists of complex optical-mechanical systems isolated from the ground by multiple layers of active seismic isolation, all controlled by hundreds of fast, digital, feedback control systems. This article describes a novel state machine-based automation platform developed to handle the automation and supervisory control challenges of these detectors...

PURPOSE: Falls are a major safety issue in rehabilitation settings. Patients receive mixed messages-try to be as independent as possible, but don't do anything in your room without calling for assistance. Despite the use of multiple falls interventions at this facility, the fall rate remained high. To impact this rate, the facility implemented a video monitoring system. This system allows for patients at risk for falling to be monitored from a remote location. The monitor technician is able to speak to the patient directly and/or contact staff members to respond to the room, preventing a fall...

Specific cell adhesion and osteogenicity are both crucial factors for the long-term success of titanium implants. In this work, two mussel-derived bioactive peptides were designed to one-step dual-biofunctionalization of titanium implants via robust catechol/TiO2 coordinative interactions. The highly biomimetic peptides capped with integrin-targeted sequence or osteogenic growth sequence could efficiently improve the biocompatibilities of titanium implants and endow the implants with abilities to induce specific cell adhesion and enhanced osteogenicity...

Polycyclic aromatic hydrocarbons (PAHs) are an important class of water pollutants because of their known ecological and human toxicity. Electrocoagulation (EC) is a promising technology for mitigating industrial wastewater pollution, but the removal and transformation of PAHs during EC treatment has not yet been understood. Therefore, a paper-making wastewater effluent (PMWW) was employed in this study to investigate the relationship between PAHs' removal and transformation during EC treatment. The results show that 86% of PAHs were effectively removed not only by the electro-oxidation reactions, but also by adsorption onto Fe hydroxide flocs...

Biomedical research has relied on animal studies and conventional cell cultures for decades. Recently, microphysiological systems (MPS), also known as organs-on-chips, that recapitulate the structure and function of native tissues in vitro, have emerged as a promising alternative. However, current MPS typically lack integrated sensors and their fabrication requires multi-step lithographic processes. Here, we introduce a facile route for fabricating a new class of instrumented cardiac microphysiological devices via multimaterial three-dimensional (3D) printing...

: The complex network of biochemical and biophysical cues in the pancreatic desmoplasia not only presents challenges to the fundamental understanding of tumor progression, but also hinders the development of therapeutic strategies against pancreatic cancer. Residing in the desmoplasia, pancreatic stellate cells (PSCs) are the major stromal cells affecting the growth and metastasis of pancreatic cancer cells by means of paracrine effects and extracellular matrix protein deposition. PSCs remain in a quiescent/dormant state until they are 'activated' by various environmental cues...

Skilled nursing facilities (SNF) have emerged as an integral component of care for older adults with heart failure (HF). Despite their prominent role, poor clinical outcomes for the medically complex patients with HF managed in SNFs are common. Barriers to providing quality care include poor transitional care during hospital-to-SNF and SNF-to-community discharges, lack of HF training among SNF staff, and a lack of a standardized care process among SNF facilities. While no evidence-based practice standards have been established, various measures and tools designed to improve HF management in SNFs are being investigated...
