Article Synopsis
  • The study investigates CP symmetry violation in the decay of D^{+} particles into K^{-}K^{+}π^{+} using data from proton-proton collisions at a high energy of 13 TeV.
  • A unique model-independent method was employed to analyze the phase-space distributions of D^{+} and D^{-} particles, correcting for any instrumental biases using D_{s}^{+} decays.
  • The findings indicate no significant evidence of CP violation, with a p value of 8.1%, and measure specific CP asymmetry observables, marking this study as the most sensitive search of its kind in multibody decays.

Background: A significant number of individuals diagnosed with SARS-CoV-2 continue to suffer from persistent symptoms, a condition commonly referred to as Post-COVID syndrome (PCS). The most common manifestations are fatigue, post-exertional malaise, respiratory problems and cognitive deficits due to the lack of a causal treatment, therapeutic options remain symptom oriented. The aim of this study was to develop a low-threshold group therapy concept for patients with PCS and to test its feasibility in face-to-face and online format.

Atrazine and glyphosate are considered some of the main pollutants for aquatic ecosystems, directly and indirectly affecting non-target organisms, such as amphibians. This study aimed to evaluate the sublethal effects of different concentrations of atrazine-based herbicide (ABH) and glyphosate-based herbicide (GBH) commercial formulations, both individually and in a mixture, through toxicity tests on the larval stage of Boana faber. Tadpoles were exposed to concentrations of ABH (2, 9.

Patients undergoing percutaneous coronary intervention (PCI) may experience bleeding events. Bleeding risk is increased in patients with comorbid peripheral arterial disease (PADs). To evaluate whether PCI patients with PADs have worse outcome after bleeding, we assessed pooled patient-level data of 5,989 randomized all-comer trial participants and identified those who had a bleeding (BIO-RESORT:NCT01674803, BIONYX:NCT02508714).

The Controls Over Mesopelagic Interior Carbon Storage (COMICS) cruise DY086 took place aboard the RRS Discovery in the South Atlantic during November and December, 2017. Physical, chemical, biogeochemical and biological data were collected during three visits to ocean observatory station P3, off the coast of South Georgia, during an austral spring bloom. A diverse range of equipment including CTD-rosette, Acoustic Doppler Current Profiler (ADCP), net deployments, marine snow catchers (MSCs), Stand Alone Pump System (SAPS) and PELAGRA Sediment Traps were used to produce a comprehensive, high-quality dataset.
