Determinants of Early Renal Function Recovery After TIPS in Patients With Portal Hypertension

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Renal dysfunction frequently occurs in patients with portal hypertension and is linked to unfavorable clinical outcomes. Transjugular intrahepatic portosystemic shunt (TIPS) has the potential to enhance renal perfusion through portal decompression; however, factors predicting early improvement in renal function remain insufficiently defined ...

The effect of microsilica and refractory cement content on the properties of andalusite based Low Cement Castables used in aluminum casthouse O efeito do teor de microsílica e de cimento refratário nas propriedades de LCCs usados em moldagem de alumínio

open access: yesCerâmica, 2010
The bonding system in low cement castables is achieved by the use of calcium aluminate cement, microsilica and reactive alumina. The lime/silica ratio critically impacts the liquid phase formation at high temperatures and subsequently the corrosion ...

Hot Corrosion Type X: Behavior of Mo‐Si‐B at Different Temperatures

open access: yesMaterials and Corrosion, EarlyView.
The temperature‐dependent mechanism for Mo‐Si‐B is investigated by studying the hot corrosion resistance of Mo‐Si‐B at 500°C–900°C. Post‐testing analysis via XRD, SEM, Raman and EPMA is used to reveal the degradation mechanisms. Na2MoO4, which forms under Na2SO4 deposits, is responsible for dissolving the surrounding material due to its lower melting ...

Concretos refratários preparados com alumina hidratável: efeito dos dispersantes Refractory castables prepared with hydratable alumina: the dispersant effect

open access: yesCerâmica, 2009
Uma alumina de transição capaz de formar fases hidratadas em água tem sido utilizada como ligante hidráulico alternativo para concretos refratários. Entretanto, têm-se observado que a secagem de concretos preparados com este ligante é normalmente mais ...

Recent Advances in Cryogel Applications for Musculoskeletal Regeneration

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Hydrogels have been widely used in tissue engineering due to their high‐water content and biocompatibility, yet their densely cross‐linked microstructure inherently limits cell infiltration, mass transport, and mechanical support. Cryogels, formed through partial freezing and crosslinking under subzero conditions, provide unique 3D macroporous

Breaking Extrapolation Barriers: Dual Innovations for Property and Component Design of Multi‐Component Alloy

open access: yesMaterials Genome Engineering Advances, EarlyView.
This study breaks extrapolation barriers in alloy design by merging symbolic regression with latent space sampling. The dual‐strategy framework enables accurate prediction of high‐hardness properties and navigates uncharted compositional spaces. The approach successfully designs novel high‐entropy alloys with hardness exceeding 863.5 HV, demonstrating ...

Knowledge‐Constrained Multi‐Objective Reinforcement Learning for Simultaneous Optimization of Printability and Mechanical Properties in Additively Manufactured Superalloys

open access: yesMaterials Genome Engineering Advances, EarlyView.
A knowledge‐constrained multi‐objective reinforcement learning (MORL) framework is proposed, embedding cracking susceptibility as a hard constraint to simultaneously optimize printability and mechanical properties of additively manufactured superalloys.
