Bioprosthetic Valve Failure After Transcatheter Aortic Valve Replacement

BACKGROUND: Data on the long-term incidence and clinical impact of bioprosthetic valve failure (BVF) after transcatheter aortic valve replacement remain limited. This study aimed to assess the incidence, predictors, and clinical impact of BVF following transcatheter aortic valve...

Energy-level alignment of vacancy-ordered halide double perovskites

Vacancy-ordered double perovskites have emerged as lead-free alternatives, offering remarkable stability and compositional tunability for optoelectronic applications. In this study, we provide first-principles insights into their electronic properties, surface stability, and ener...

Facing Yourself: A Proxemic Approach to Self-Dyadic Interactions in VR

Virtual Reality (VR) provides a powerful framework for studying human social interactions, yet generating realistic and diverse interaction data remains a major challenge. Asynchronous Interaction (AsI) paradigms offer a promising alternative by enabling users to interact with th...

How Does Motion-to-Photon Latency Influence the Perception-Action Loop

The perception-action loop plays an essential role in sports performance. Virtual reality is increasingly used to train this loop because it provides a controlled setting. However, motion-to-photon latency, the delay between the user’s real and virtual motion, may disrupt user ex...

Hidden genomic structure and widespread structural polymorphism across environmental gradients in the spiny sea star Marthasterias glacialis

Abstract Genomic regions of reduced recombination can preserve linkage among co-adapted alleles, facilitating local adaptation despite high connectivity. Such regions—often generated by chromosomal inversions—may be especially important in highly dispersive marine taxa yet remain...

Referent Mention When Parents Tell a Story: A Means to Explain Children's Referential Uses in Narratives

Abstract This study aims to describe parents’ referential choices while recounting a story to their child. Indeed, in choosing referring expressions (REs), until the 8 years of age or even later, children are less sensitive to discourse accessibility than factors such as visual a...

Tailoring Liquid Crystalline Self‐Assembly and Photophysical Properties of Unsymmetrical Fluorenones via Polar Terminal Groups

ABSTRACT In this work, a series of novel unsymmetrical fluorenone derivatives bearing various head groups (H, Br, NO 2 , NH 2 , and CN) was synthesized and investigated with respect to their mesomorphic and photophysical properties. Depending on the head group, SmA, N, or SmC pha...

A ComplexSpin-Transition Thermal Hysteresis Unlockedby Two Competing Symmetry-Breakings

Abstract The spin-crossover material [Fe(NH2trz)3](NO3)2 belongs to the class of 1D triazole-based polymeric SCO complexes. It exhibits a thermal phase transition, with a 28 K wide thermal hysteresis, characterized by phase transition temperatures T↑ = 346 K upon warming and T↓ =...

CRISPR screens reveal MCT1-driven metabolic escape from SMAD3 inhibition as a therapeutic vulnerability

Resistance to therapy remains a critical challenge in cancer. This is exemplified by TGF-β pathway inhibitors which, despite broad clinical testing, have failed to deliver survival benefit. More precise SMAD3 targeting has shown preclinical promise, yet resistance mechanisms to S...

Pressure-SelectiveMagnetic Switching via SpatiallySeparated Soft Interlayer and Rigid Charge-Transfer Intralayer

Abstract We report a pressure-responsive molecule-based magnet featuring a layered cyanido-bridged Co–W assembly, [{CoII(4-phenoxypyridine)4}3{WV(CN)8}2], exhibiting a distinct pressure-selective magnetic behavior. The compound forms two-dimensional charge-transfer layers with la...
