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

Size effect on the shear damage under low stress triaxiality in micro-scaled plastic deformation of metallic materials

open access: yesMaterials & Design, 2020
Micro-forming is one of the major micro-manufacturing methods with promising application potentials, in which the damage response and fracture behavior need to be insightfully addressed.

Hardening effects on formability limit prediction based on gurson-type damage models and bifurcation analysis [PDF]

open access: yes, 2017
In this work, ductility limits of metallic materials, associated with the occurrence of strain localization, are predicted using the GTN damage model coupled with bifurcation theory.

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 ...

Post‐Discharge Opioid Prescribing After Elective Colorectal Resection: An International Survey

open access: yesWorld Journal of Surgery, Volume 50, Issue 3, Page 558-568, March 2026.
Excessive opioid prescribing after colorectal surgery can lead to adverse events and contribute to the opioid crisis. Understanding international prescribing patterns is essential for guiding practice and future research. The Analgesia After Colorectal Surgery (ACORE) survey aimed to characterize international opioid prescribing practices after ...

Experimental determination and numerical simulation of material and damage behaviour of 3D printed polyamide 12 under quasi-static loading

open access: yesArchives of Mechanics, 2019
In order to characterise the material and damage behaviour of additively manufactured polyamide 12 (PA12) under quasi-static load and to implement it in a numerical model, experiments under quasi-static load as well as microstructural investigations were

Study on the Influence of the Gurson–Tvergaard–Needleman Damage Model on the Fatigue Crack Growth Rate

open access: yesMetals, 2021
The fatigue crack growth (FCG) process is usually accessed through the stress intensity factor range, ΔK, which has some limitations. The cumulative plastic strain at the crack tip has provided results in good agreement with the experimental observations.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,
