Article Synopsis
  • The article discusses the development of a high-accuracy GPS-denied ad hoc localization system using ultra-wideband technology for mobile and stationary robots in dynamic environments.
  • The method involves initial localization of unmanned ground vehicles (UGVs) utilizing surrounding anchor points, followed by refinement using an unscented Kalman filter that combines odometry and range measures.
  • The process fosters collaboration among robots to enhance collective localization estimates, enabling them to function as a cohesive mobile ad hoc network.

Background: Hutchinson-Gilford progeria syndrome (HGPS) is an ultrarare, fatal, premature aging disease caused by a toxic protein called progerin. Circulating progerin has not been previously detected, precluding research using readily available biological samples. This study aimed to develop a plasma progerin assay to evaluate progerin's quantity, response to progerin-targeted therapy, and relationship to patient survival.

Introduction: People with serious mental illness (SMI) have poor health outcomes, in part because of inequitable access to quality health services. Primary care is well suited to coordinate and manage care for this population; however, providers may feel ill-equipped to do so and patients may not have the support and resources required to coordinate their care. We lack a strong understanding of prevention and management of chronic disease in primary care among people with SMI as well as the context-specific barriers that exist at the patient, provider and system levels.

Background: Incarcerated women have a higher prevalence of health problems than the general population; however, little is known about their perspectives on the healthcare they receive. Here, we conducted semi-structured interviews with women who had been incarcerated (n = 63) which asked what they would tell healthcare decision-makers about their experiences of healthcare in prisons and the community post-incarceration if provided the opportunity. All participants had a history of sexual violence victimization and had at least one period of incarceration in a community corrections center in Arkansas due to the goals of the larger study from which data were drawn.

Introduction: Clinical studies conducted in the early to mid-twentieth century, and recent self-reports by some maternal placentophagy practitioners, suggest that human maternal placentophagy improves breast milk quality and quantity, although little research has evaluated this claim. Some placentophagy providers and advocates suggest that increased prolactin levels after placenta ingestion could account for the purported lactation benefits. The current study was conducted to evaluate these claims by comparing plasma prolactin levels of women consuming steamed, dehydrated, and encapsulated placenta with those of women consuming a placebo.
