Characterization and Catalytic Properties of Nano-Sized Au Metal Catalyst on Titanium Containing High Mesoporous Silica (Ti-HMS) Synthesized by Photo-Assisted Deposition and Impregnation Methods

open access: yesInternational Journal of Photoenergy, 2011
The photo-assisted deposition (PAD) and impregnation (img) synthesis of nano-sized Au metal on Ti-HMS are reported. The prepared catalysts were characterized by different techniques such as XRD, XAFS, TEM and nitrogen adsorption analysis.

Data‐Driven Design of Bimodal Networked Dielectric Elastomers for High‐Performance Artificial Muscles

open access: yesAdvanced Intelligent Systems, EarlyView.
A data‐efficient artificial intelligence‐assisted framework, which integrates experimental data with machine learning, is developed for the design of bimodal networked dielectric elastomers (DEs) as advanced artificial muscles. It adopts neural networks to predict DEs’ mechanical properties and support vector machines to classify electromechanical ...

Mutability and importance of a hypermutable cell subpopulation that produces stress-induced mutants in Escherichia coli.

open access: yesPLoS Genetics, 2008
In bacterial, yeast, and human cells, stress-induced mutation mechanisms are induced in growth-limiting environments and produce non-adaptive and adaptive mutations.

A Memristor‐Based In‐Memory Computing System‐on‐Chip with Efficient Depthwise Convolution

open access: yesAdvanced Intelligent Systems, EarlyView.
We present a memristor‐based in‐memory computing (IMC) architecture that enables efficient depthwise convolution (DWC) acceleration. Fabricated in a system‐on‐chip with crossbar arrays, the design improves memory utilization. Experimental validation demonstrates the first hardware acceleration of DWC in IMC, achieving a digital comparable inference ...

Therapeutic Outcomes in VEXAS Syndrome: A Multicenter Comparative Cohort of Allogeneic Hematopoietic Stem Cell Transplantation and Hypomethylating Agents

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Hypomethylating agents (HMA) and allogeneic hematopoietic stem cell transplantation (alloHSCT) have both demonstrated remissions in VEXAS; however, comparative data is lacking. We conducted a multicenter, retrospective analysis of 66 patients diagnosed with VEXAS syndrome treated with HMA (n = 35) or alloHSCT (n = 31). Baseline characteristics

35 Individuals With HUWE1‐Related Neurodevelopmental Disorder and Suggested Clinical Evaluations

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT HUWE1 (HECT, UBA, and WWE Domain Containing E3 Ubiquitin Protein Ligase1, OMIM 300697), located at Xp11.22, encodes a ubiquitin ligase that is highly conserved across species. Genetic variants in HUWE1 described in multiple independent studies cause X‐linked intellectual disability, including in the patients identified by Juberg, Marsidi, and ...

Evaluation of cardiac histology and cell death markers during the progression of diabetes in a streptozotocin‐induced diabetes rat model

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Daily insulin administration in streptozotocin‐induced diabetic rats prevented cardiac damage associated with diabetic cardiomyopathy, including hypertrophy, fibrosis, and expression of cell death markers, at 12 weeks. However, cyclophilin D, a marker of mitochondrial permeability transition pore‐opening‐associated cell death (necrosis), was observed ...

Early diabetes‐like phenotypes in germ‐free mice induced by gut microbiota from patients with type 2 diabetes

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Gut microbiota from patients with type 2 diabetes induced early diabetes‐like phenotypes in germ‐free mice, including progressive glucose intolerance and mild renal injury. Longitudinal profiling revealed persistent dysbiosis preceding stable metabolic dysfunction, with coordinated fecal and plasma metabolite alterations and a prominent L‐Dopa ...

Natural Aging of Biomaterials in Ambient and Physiological Environments

open access: yesAdvanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Characterizing Heterogeneity in Post‐Consumer Rigid PP Packaging Waste: Implications for Object and Property‐Based Flake Sorting

open access: yesJournal of Applied Polymer Science, EarlyView.
Commercial PP packaging grades span wide ranges in melt flow rate and stiffness, defining distinct application‐specific property spaces. Post‐consumer rigid PP products populate these spaces heterogeneously, with processing method and degradation shifting properties beyond virgin grade benchmarks.
