Damage identification parameters of dual-phase 600–800 steels based on experimental void analysis and finite element simulations

Journal of Materials Research and Technology, 2019
In this work, the damage behavior of cold-rolled zinc-coated dual-phase steel sheets 600 and 800 grades was evaluated by means of standard uniaxial tensile testing, microstructural characterization and finite element modeling.

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

Clinical 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

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

Advanced 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

World 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 ...

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

Reviews 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,

Age‐Associated Dysregulation of Postsynaptic Mitochondria Perturbs Reinnervation Kinetics

Aging Cell, Volume 25, Issue 1, January 2026.
We show that aging results in postsynaptic mitochondrial loss at the neuromuscular junction and impaired muscle reinnervation. In vivo CRISPR knockout of mitochondrial genes, CHCHD10 and CHCHD2, in young muscles led to fragmented endplates, aberrant innervation, and impaired transcriptional maturation of sub‐synaptic myonuclei during regeneration ...

Pyrolysis of Onion Peel Waste: Investigation of Comprehensive Pyrolysis Index, Reaction Mechanism, Kinetic, and Thermodynamic Properties Using TGA Analysis

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
The rising demand for onion production results in significant waste, harming the environment. Onion waste is unsuitable for animal feed and difficult to dispose of due to its strong odor and potential for phytopathogen growth. Pyrolysis is a promising method for repurposing food waste, requiring minimal infrastructure and offering rapid processing and ...

Hyaluronic Acid Hydrogel Inhibits Autophagy Through the miR‐181a‐5p/ATG5 Molecular Axis to Promote the Adipogenic Differentiation of Adipose‐Derived Stem Cells

Stem Cells International, Volume 2026, Issue 1, 2026.
Background Soft tissue defects refer to defects in or damage to human soft tissue, which may affect the appearance, function, and health of the human body and cause physical and psychological distress to the patient. Hyaluronic acid (HA), a fillable material in the field of plastic medicine, could play a crucial role in reconstructing soft tissues and ...

GTN Model-Based Material Parameters of AZ31 Magnesium Sheet at Various Temperatures by Means of SEM In-Situ Testing

Crystals, 2020
Magnesium alloys are primarily associated with complex forming mechanisms, which yield ductility at high temperatures. In sheet metal forming, high triaxiality stress states that favor the ductile damage mechanisms of void formation and growth are known ...
