Theoretical analysis and optimal design of LLC resonant converter

, 2007
A LLC resonant topology is analyzed to derive efficiency and cost optimal design for wide input ranges and load variations. In the LLC converter, a wide range of output power is controlled with only a narrow variation in operating frequency since this ...

Dihydroartemisinin Engages NQO1 and Promotes Ferroptosis‐Related Oxidative Stress in Non‐Small Cell Lung Cancer

Phytotherapy Research, EarlyView.
Dihydroartemisinin Engages NQO1 and Promotes Ferroptosis‐Related Oxidative Stress in Non‐Small Cell Lung Cancer. ABSTRACT Dihydroartemisinin (DHA), a bioactive derivative of Artemisia annua L. (AAL), has shown antitumor activity in several malignancies, including non‐small cell lung cancer (NSCLC).

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

Responsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and

Energy Security and Sustainability in the GCC: The Conditional and Contested Role of AI and Digital Infrastructure

Sustainable Development, EarlyView.
ABSTRACT As Gulf Cooperation Council (GCC) economies pursue simultaneous commitments to national AI strategies, renewable energy targets, and Paris Agreement pledges, a key sustainable‐management question remains empirically unresolved: does digital and AI investment genuinely advance energy security and environmental sustainability in hydrocarbon ...

3D‐printed model for resection of positive surgical margins in robot‐assisted prostatectomy

BJU International, Volume 135, Issue 4, Page 657-667, April 2025.
Objectives To improve precision of secondary resection (SR) after positive surgical margin (PSM) detection by frozen section (FS) during nerve‐sparing (NS) robot‐assisted radical prostatectomy (RARP) by employing a personalised three‐dimensional (3D)‐printed prostate model derived from pelvic magnetic resonance imaging (MRI).

Extracellular vesicles in pharmacology: Innovations in drug delivery and therapeutic applications in cancer

British Journal of Pharmacology, EarlyView.
Extracellular vesicles (EVs) are a diverse population of membrane nanoparticles secreted by nearly all cell types, playing a key role in intercellular communication by transferring bioactive macromolecular cargo. In cancer, EVs shape both the local tumour microenvironment and distant premetastatic niches.

From productive coupling to catalytic commitment: An evolutionarily tuned interdomain connector in Leishmania Aha1 orchestrates Hsp90 activation

The FEBS Journal, EarlyView.
LbAha1 activates LbHsp90 through a multistep mechanism in which productive N‐domain docking precedes ATP‐driven rearrangement and linker ordering. The LbAha1 linker transitions from a flexible to helical state, stabilizing an asymmetric, catalytically competent closed complex.

The molecular basis of GshT substrate binding reveals how Streptococcus pneumoniae acquires the antioxidant glutathione

The FEBS Journal, EarlyView.
Streptococcus pneumoniae imports glutathione (GSH) from its obligate human host to defend against oxidative stress. GSH import is facilitated through the substrate binding protein (SBP) GshT, relying on charge complementarity between the protein and ligand.

Post‐traumatic headache: A two‐arm parallel‐group, randomized, single‐blind, sham‐controlled clinical superiority trial evaluating repetitive transcranial magnetic stimulation as a novel treatment modality

Headache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective This study aimed to evaluate the effect of repetitive transcranial magnetic stimulation (rTMS) on persistent post‐traumatic headache (pPTH) in adults with pPTH and a high burden of persistent post‐concussion symptoms (pPCS) 4–5 months after mild traumatic brain injury (mTBI).
