Photothermomechanically Efficient, Low‐Cost, High‐Cycle‐Life, Hybrid MXene‐Polymer Actuators

Advanced Materials Technologies, EarlyView.
The addition of MXenes to elastomer‐plastic‐paper films enables the creation of easily prepared actuators that are scalable for small robotic applications. Known as MXene‐polymer Trilayer Actuators (MPTAs), they bend from UV light. Their usefulness is demonstrated through kirigami‐inspired flower‐shaped art design, parallel manipulator for waveguiding,

Differences in carbohydrate content of low density lipoproteins associated with low density lipoprotein subclass patterns

Journal of Lipid Research, 1990
The neutral carbohydrate content of both the protein (apoB) and lipid fractions of low density lipoproteins (LDL) from subjects with a predominance of small, dense LDL (subclass pattern B) was found to be lower than in subjects with larger LDL (subclass ...

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...

IgG subclass deficiency in children with recurrent infections

The Turkish Journal of Pediatrics, 1991
IgG subclass levels were studied in 12 children, aged between 2.5-12 years with recurrent respiratory tract infections. They did not have low IgG levels or IgA deficiency. We found combined deficiency of IgG2-IgG4 in one patient and selective IgG2

Dual activity of PNGM-1 pinpoints the evolutionary origin of subclass B3 metallo-β-lactamases: a molecular and evolutionary study

Emerging Microbes and Infections, 2019
Resistance to β-lactams is one of the most serious problems associated with Gram-negative infections. β-Lactamases are able to hydrolyze β-lactams such as cephalosporins and/or carbapenems.

Continual Learning for Multimodal Data Fusion of a Soft Gripper

Advanced Robotics Research, EarlyView.
Models trained on a single data modality often struggle to generalize when exposed to a different modality. This work introduces a continual learning algorithm capable of incrementally learning different data modalities by leveraging both class‐incremental and domain‐incremental learning scenarios in an artificial environment where labeled data is ...

Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants

Advanced Science, EarlyView.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium

A Novel Subclass of Harmonic Functions: Coefficient Bounds, Distortion Bounds, and Closure Properties

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi
In this paper, we introduce a new subclass of harmonic functions that significantly improves our understanding of these functions in geometric function theory. We provide a comprehensive analysis of this subclass by deriving several important properties,

A subclass of dendritic cells kills CD4 T cells via Fas/Fas-ligand- induced apoptosis

Journal of Experimental Medicine, 1996
Dendritic cells (DC), the most efficient antigen-presenting cells, are well equipped for activation of naive CD4+ T cells by their expression of high levels of major histocompatibility complex and costimulator molecules.
