Generative approach for lensless imaging in low-light conditions.

Lensless imaging offers a lightweight, compact alternative to traditional lens-based systems, ideal for exploration in space-constrained environments. However, the absence of a focusing lens and limited lighting in such environments often results in low-light conditions, where the measurements suffer from complex noise interference due to insufficient capture of photons. This study presents a robust reconstruction method for high-quality imaging in low-light scenarios, employing two complementary perspectives: model-driven and data-driven.

Clinical Variables Associated With Impaired Consciousness in Hospitalized COVID-19 Patients.

Background: Impaired consciousness is associated with complications and mortality in COVID-19 patients. We study factors associated with impaired consciousness as measured by the Glasgow Coma Scale (GCS) in COVID-19 patients.

Methods: This is a retrospective study of 604 patients with COVID-19 in the metropolitan New York City area.

Optimized breath analysis: customized analytical methods and enhanced workflow for broader detection of VOCs.

Introduction: Breath Volatile organic compounds (VOCs) are promising biomarkers for clinical purposes due to their unique properties. Translation of VOC biomarkers into the clinic depends on identification and validation: a challenge requiring collaboration, well-established protocols, and cross-comparison of data. Previously, we developed a breath collection and analysis method, resulting in 148 breath-borne VOCs identified.

PET/CT with Myocardial Blood Flow Assessment Is Prognostic of Cardiac Allograft Vasculopathy Progression and Clinical Outcomes.

Cardiac allograft vasculopathy (CAV) causes impaired blood flow in both epicardial vessels and microvasculature and remains a leading cause of posttransplant morbidity and mortality. This study examined the prognostic value and outcomes of CAV, assessed by N-ammonia PET/CT myocardial perfusion imaging in heart transplant recipients. PET/CT and invasive coronary angiography (ICA) were graded using validated scales.
