Introduction: The Aveir Dual-Chamber (DR) is the first entirely intracardiac dual-chamber leadless pacing system. Implantation of this device is typically achieved via femoral access, which may be a significant obstacle in patients with complex femoral vasculature or contraindications to femoral access.
Methods And Results: This report describes the world's first three cases of dual-chamber leadless pacemaker implantation via the right internal jugular vein.
A comprehensive study of the angular distributions in the bottom-baryon decays Λ_{b}^{0}→Λ_{c}^{+}h^{-}(h=π,K), followed by Λ_{c}^{+}→Λh^{+} with Λ→pπ^{-} or Λ_{c}^{+}→pK_{S}^{0} decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9 fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

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.

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.

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.

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.

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.

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.
View Article and Find Full Text PDFEngineering 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.

Unlike the other phosphonate derivatives in this series, GdDOTA-1AmP showed a surprisingly smooth increase in relaxivity from 3.0 to 6.

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.

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.
