Percutaneous Coronary Intervention to Spontaneous Coronary Artery Dissection With Coexistent Takotsubo Cardiomyopathy: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
A case of spontaneous coronary artery dissection (SCAD) of the first diagonal branch (D1) with co‐existent Takotsubo Cardiomyopathy (TC), successfully revascularised with percutaneous coronary intervention (PCI). ABSTRACT Spontaneous coronary artery dissection (SCAD) is an uncommon cause of non‐atherosclerotic acute coronary syndrome (ACS) resulting in

Impact of Tenofovir Alafenamide Sub‐Dermal Implant Insertion Site Scarring on Acceptability and HIV Prevention Preferences: A Prospective Cohort Study in Durban, South Africa

open access: yesJournal of the International AIDS Society, Volume 29, Issue 4, April 2026.
ABSTRACT Introduction The CAPRISA 018 Phase I trial evaluated the safety, tolerability and pharmacokinetics of a 110 mg tenofovir alafenamide (TAF) implant for HIV prevention in South African women. This follow‐up cohort study, CAPRISA 097, assessed the long‐term resolution of implant site reactions (ISRs) after implant removal and explored user ...

Failure and strain gradient analyses in incremental forming using GTN model

open access: yesInternational Journal of Lightweight Materials and Manufacture, 2019
Single point incremental forming (SPIF) process is gaining popularity for rapid manufacturing of complex 3D shapes. The present study is aimed at numerically predicting the failure using the Gurson-Tvergaard-Needleman (GTN) model and further clarifying ...

A model independent determination of $|V_{ub}|$ using the global $q^2$ dependence of the dispersive bounds on the $B\to\pi l\nu$ form factors

open access: yes, 2004
We propose a method to determine the CKM matrix element $|V_{ub}|$ using the global $q^2$ dependence of the dispersive bound on the form factors for $B\to \pi l\nu$ decay. Since the lattice calculation of the $B\to \pi l\nu$ form factor is limited to the

Global Warming Amplifies the Risk of Uncertainties in Projections of Deepened Summer Thaw Depth Across Northern Hemisphere Zone

open access: yesEarth's Future, Volume 14, Issue 4, April 2026.
Abstract A warming climate endangered to destabilize the expansive permafrost zone and its summer thaw depth in the northern part of the earth. This climatic shift exacerbated the challenges associated with predicting future summer thaw depths, thereby escalating the associated risks.

On large-sample estimation and testing via quadratic inference functions for correlated data [PDF]

open access: yes, 2005
Hansen (1982) proposed a class of "generalized method of moments" (GMMs) for estimating a vector of regression parameters from a set of score functions.

Artificial intelligence streamlines scientific discovery of drug–target interactions

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 8, Page 1673-1690, April 2026.
Abstract Drug discovery is a complicated process through which new therapeutics are identified to prevent and treat specific diseases. Identification of drug–target interactions (DTIs) stands as a pivotal aspect within the realm of drug discovery and development. The traditional process of drug discovery, especially identification of DTIs, is marked by

S3RL: Enhancing Spatial Single‐Cell Transcriptomics With Separable Representation Learning

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
Separable Spatial Representation Learning (S3RL) is introduced to enhance the reconstruction of spatial transcriptomic landscapes by disentangling spatial structure and gene expression semantics. By integrating multimodal inputs with graph‐based representation learning and hyperspherical prototype modeling, S3RL enables high‐fidelity spatial domain ...
