T-Type-Based Dual-Active-Bridge DC-DC Converter With Voltage Balancing Capability for Bipolar DC Distribution System

open access: yesIEEE Access
A dual-active-bridge (DAB) converter has been widely used to construct the dc bus voltage of a dc distribution system. However, in the case of a bipolar dc system, conventional DAB converters fail to regulate the bipolar dc bus voltage levels due to the ...

Simulation, Analysis and Hardware Implementation Strategy of DAB Converter

open access: yes
The paper presents the Simulation and Hardware Implementation Strategy of a Dual Active Bridge (DAB) Converter. The Study focuses on optimizing Efficiency, Power Density and Bi-Directional Power Flow while ensuring Zero Voltage Switching (ZVS). The Simulation is performed in PLECS and the Hardware Implementation Strategy is demonstrated.

Bioadhesive Hydrogel With Polyphenol‐Armored Nanogene Rejuvenates Chondrocyte Senescence for Aged Osteoarthritis Therapy

open access: yesAdvanced Science, EarlyView.
An adhesive hydrogel depot with polyphenol‐armored nanogenes is developed for treating aged osteoarthritis. This system maintains miR‐140 bioactivity, prolongs its intra‐articular retention, and enhances transfection into chondrocytes, leading to the downregulation of senescence‐associated pathways.

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

open access: yesAdvanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

open access: yesAdvanced Science, EarlyView.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

Paternal Caffeine Exposure Programs Offspring Stress Vulnerability via Sperm Dlk1‐Dio3 Imprinting‐Directed Remodeling of a Novel Neural Circuit

open access: yesAdvanced Science, EarlyView.
The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.

Integrated Single‐Cell and Spatial Analysis Reveals a Metabolic‐Immune Axis Driving Aortic Dissection

open access: yesAdvanced Science, EarlyView.
Single‐cell and spatial profiling of 110 human thoracic aortic samples reveals a stromal–immune circuit driving aortic dissection. An elastin‐rich fibroblast subset is depleted with age and markedly reduced in disease, weakening aortic wall integrity.

GLS1 Orchestrates Exosome‐Mediated Tumor‐Endothelial Communication to Facilitate Angiogenesis

open access: yesAdvanced Science, EarlyView.
This study reveals a previously unappreciated, non‐metabolic function of GLS1 in the control of tumor angiogenesis via exosome‐mediated CAV1‐TNC signaling, indicating that therapeutic targeting of GLS1 may offer a dual benefit by simultaneously suppressing tumor metabolic activity and angiogenic processes in head and neck cancer. ABSTRACT Glutaminase 1

Drug‐Induced Cuproptosis Defines the Therapeutic Window of Celecoxib in Intervertebral Disc Degeneration via the HSP90‐RBX1 Axis

open access: yesAdvanced Science, EarlyView.
This study reveals the dual role of celecoxib in intervertebral disc degeneration. While low concentrations are protective, high concentrations induce toxicity by upregulating HSP90, which synergizes with USP15 to deubiquitinate and stabilize RBX1. This leads to degradation of COMMD1/ATP7B, copper dyshomeostasis, and ultimately, cuproptosis.

CD44‐Targeting Hydroxyapatite Nanoparticles (HAP) Induce Mitochondrial Dysfunction‐Driven PANoptosis and Immunogenic Cell Death (ICD) via Ca Overload in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
ABSTRACT Colorectal cancer (CRC) remains therapeutically challenging due to high metastasis, recurrence, and immunotherapy resistance driven by tumor microenvironment‐mediated immune evasion. Immunogenic cell death (ICD) offers a promising strategy to reshape the immune microenvironment, yet existing ICD inducers suffer from poor targeting efficiency ...
