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.

Replications are important for assessing the reliability of published findings. However, they are costly, and it is infeasible to replicate everything. Accurate, fast, lower-cost alternatives such as eliciting predictions could accelerate assessment for rapid policy implementation in a crisis and help guide a more efficient allocation of scarce replication resources.

Relative to other regions of the body, the ear has a high risk of developing cutaneous malignancies that often necessitate Mohs micrographic surgery (MMS) for removal. This procedure can create defects that are immediately noticeable if left untreated. Reconstructive techniques are often needed to restore the appearance of the affected ear and its symmetrical relationship to the contralateral ear.

Latent variable modeling as a lens for psychometric theory is a popular tool for social scientists to examine measurement of constructs. Journals, such as regularly publish articles supporting measures of latent constructs wherein a measurement model is established. Confirmatory factor analysis can be used to investigate the replicability and generalizability of the measurement model in new samples, while multigroup confirmatory factor analysis is used to examine the measurement model across groups within samples.

Article Synopsis
  • A study was conducted on B^{+} decays to explore resonant structures using data from the LHCb experiment at various energy levels, totaling an integrated luminosity of 9 fb^{-1}.
  • The researchers performed a simultaneous amplitude fit on two decay channels, determining the C parities of resonances in the D^{*±}D^{∓} mass spectra.
  • Four new charmonium or charmoniumlike states were discovered, including η_{c}(3945) and h_{c}(4000), and the presence of T_{c[over ¯]s[over ¯]0}^{*}(2870)^{0} and T_{c[over ¯]s

Background: Endovascular interventions for peripheral artery disease have increased in prevalence over time given the inherent benefits of minimally invasive approaches. Although it is essential that vascular surgery graduates are facile with endovascular techniques, the results of the BEST-CLI (Best Endovascular vs. Best Surgical Therapy in Patients With Critical Limb Ischemia) trial highlight the equivalent importance of ensuring trainee competence in open skills.

  • A 29-year-old Iranian male was diagnosed with Jalili-Smith syndrome (JSS), a rare genetic disorder that causes vision and dental issues, and he presented with acute angle closure glaucoma.
  • JSS typically features symptoms like photophobia, nystagmus, and enamel problems, with many cases observed in areas such as the Gaza Strip, often linked to consanguinity.
  • The patient's condition included several complications, such as cataracts and retinal thinning, and he underwent a unique surgery involving cataract removal and minimally invasive glaucoma procedures, which have not been documented before for JSS patients.

Purpose: Many rural areas lack brick-and-mortar HIV prevention resources despite the increasing rates of HIV. Although online HIV pre-exposure prophylaxis (PrEP) programs can potentially increase uptake among rural sexual minority men (SMM), their attitudes and preferences regarding telehealth-based PrEP (telePrEP) programming are uncertain. This qualitative study examined rural SMM's perceived risks and benefits of participating in a hypothetical telePrEP program.

A measurement of time-dependent CP violation in D^{0}→π^{+}π^{-}π^{0} decays using a pp collision data sample collected by the LHCb experiment in 2012 and from 2015 to 2018, corresponding to an integrated luminosity of 7.7  fb^{-1}, is presented. The initial flavor of each D^{0} candidate is determined from the charge of the pion produced in the D^{*}(2010)^{+}→D^{0}π^{+} decay.

Engineering design optimization poses a significant challenge, usually requiring human expertise to discover superior solutions. Although various search techniques have been employed to generate diverse designs, their effectiveness is often limited by problem-specific parameter tuning, making them less generalizable and scalable. This article introduces a framework inspired by evolutionary and developmental (evo-devo) concepts, aiming to automate the evolution of structural engineering designs.

At the height of the COVID-19 pandemic, racial/ethnic minority residents of Prince George's County were disproportionately affected by the virus. This report from the field details an intervention that trained community health workers recruited from racial/ethnic minority communities to promote COVID-19 vaccination and health literacy among racially/ethnically diverse communities.

Article Synopsis
  • A study looked at people with sciatica to see how many reported leg weakness and how many actually showed weakness when checked by doctors.
  • Most of the patients (85%) said they had weakness, but only 34% showed it when tested.
  • The difference in what people reported and what doctors observed might be influenced by how bad their leg pain was and their age.

This study was designed to test whether the single appended phosphonate group in GdDOTA-1AmP is sufficient for catalyzing the exchange of proton from the single inner-sphere water-exchanging molecule. Unlike the other phosphonate derivatives in this series, GdDOTA-1AmP showed a surprisingly smooth increase in relaxivity from 3.0 to 6.

We expect that consensus meetings, where researchers come together to discuss their theoretical viewpoints, prioritize the factors they agree are important to study, standardize their measures, and determine a smallest effect size of interest, will prove to be a more efficient solution to the lack of coordination and integration of claims in science than integrative experiments.

Zinc porphene is a two-dimensional material made of fully fused zinc porphyrins in a tetragonal lattice. It has a fully conjugated π-system, making it similar to graphene. Zinc porphene has recently been synthesized, and a combination of rough conductivity measurements and infrared and Raman spectroscopies all suggested that it is a semiconductor (Magnera, T.

Introduction: Effective pain management is crucial in cleft lip and palate (CLP) patients undergoing orthognathic surgery for earlier recovery and decreased opioid reliance. Liposomal bupivacaine (Exparel) is a local anesthetic that provides extended postoperative analgesia in adult patients; however, research on its use in adolescents is limited. This study explores the efficacy of liposomal bupivacaine for postoperative pain management in adolescent CLP patients undergoing orthognathic surgery.

In behavioral, cognitive, and social sciences, reaction time measures are an important source of information. However, analyses on reaction time data are affected by researchers' analytical choices and the order in which these choices are applied. The results of a systematic literature review, presented in this paper, revealed that the justification for and order in which analytical choices are conducted are rarely reported, leading to difficulty in reproducing results and interpreting mixed findings.
