Directly observing replica symmetry breaking in a vector quantum-optical spin glass.

Spin glasses are quintessential examples of complex matter. Although their ordering lacks complete theoretical understanding, abstract models of spin glasses inform problems in other fields, such as combinatorial optimization and artificial intelligence-where they form a mathematical basis for neural network computing. We demonstrate the ability to realize a spin glass of a distinct driven-dissipative and vector form.

Prognosis of Nonagenarian ICU Patients A Bayesian analysis of prospective European studies.

Background: As the population ages, the number of very elderly patients (≥ 90 years, nonagenarians) admitted to intensive care units (ICUs) is increasing. This trend raises concerns about the appropriateness of ICU care for this age group, especially due to the uncertainty surrounding their prognosis. Some studies suggest that elderly ICU patients have outcomes similar to slightly younger patients, but skepticism remains due to clinical judgment, cultural attitudes, and resource allocation concerns.

Using a collaborative approach to reduce falls in older people's adult mental health wards in a local health board in Wales.

Between April 2020 and March 2021, the number of fall-related emergency admissions in England for adults over 65 years was 1933 per 100 000 people. Adult patients in hospital may be at risk of falling for many reasons including a history of falls, being medically unwell, dementia or delirium, the effects of their treatment or medication, poor mobility, visual and other sensory impairments along with their general well-being. Research has shown that falls can be reduced by 20%-30% through multifactorial assessments and interventions.

Elevated right ventricular systolic pressure and outcomes after emergency hip surgery: a case control study.

Patients at risk of pulmonary hypertension frequently present for emergency orthopedic surgery. A right ventricular systolic pressure of 35 mmHg or above, calculated from a tricuspid regurgitant jet on transthoracic echocardiogram, is considered an appropriate screening test for pulmonary hypertension. The aim of this study was to evaluate the impact of an elevated right ventricular systolic pressure detected on a preoperative transthoracic echocardiogram, on outcomes after emergency hip surgery.

Network effects of traumatic brain injury: from infra slow to high frequency oscillations and seizures.

Traumatic brain injury (TBI) can have a multitude of effects on neural functioning. In extreme cases, TBI can lead to seizures both immediately following the injury as well as persistent epilepsy over years to a lifetime. However, mechanisms of neural dysfunctioning after TBI remain poorly understood.
