Design and Implementation of LLC Resonant Converter for Medical Application

open access: yes, 2016
[[abstract]]本論文提出一具有功因校正之LLC半橋諧振轉換器(LLC Resonant Converter),提供醫療儀器所需的電源供應使用,此電源轉換器主要架構分為兩級,第一級為具有主動功因校正之昇壓轉換器(Boost Converter),第二級為LLC半橋諧振轉換器作為直流電壓轉換。其中以意法半導體公司(ST)所生產的IC L6563作為主動式昇壓轉換器的控制IC,其工作模式設定為邊界導通模式(Boundary Conduction Mode)之過渡狀態(Transition Mode),

Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

A novel two phase interleaved LLC series resonant converter using a phase of the resonant capacitor

open access: yes, 2008
An LLC series resonant converter has many unique characteristics and improvements over PWM topologies. However, many output capacitors are needed in parallel to satisfy output voltage ripple and the rated ripple current of the capacitors.

Differential associations of plasma biomarkers with Alzheimer's disease and small vessel disease: A multimodal imaging study

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION We investigated how plasma biomarkers (phosphorylated tau 217 [ptau217], glial fibrillary acidic protein [GFAP], neurofilament light chain [NfL]) relate to imaging markers of small vessel disease (SVD) and Alzheimer's disease (AD), and cognition in memory clinic patients.

Prevalence of high‐risk plasma p‐tau217 levels and 5‐year transition of risk status in 70‐year‐olds

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION High‐risk plasma p‐tau217 levels predict amyloid‐β pathology in Alzheimer's disease, but little is known about the prevalence and temporal dynamics in the general population. METHODS Participants from the Gothenburg H70 Birth Cohort Study in Sweden were examined (n = 1157) and re‐examined after 5–7 years (n = 771).

Contributions of the Alzheimer's Disease Neuroimaging Initiative to advancing AD research: a targeted review of recent publications

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract The Alzheimer's Disease Neuroimaging Initiative (ADNI) recently celebrated its 20th anniversary, reflecting two decades of major contributions to Alzheimer's research through open data sharing and longitudinal multimodal assessments. This review synthesizes 122 high‐impact studies using ADNI data or biospecimens from 2023 to mid‐2025 to ...

Association of cognitive impairment and APOE ε4 with Centiloids in Hispanic and non‐Hispanic White cohorts

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Weak associations of apolipoprotein E (APOE) ε4 with cognitive impairment have been reported in Hispanic cohorts. To determine if APOE ε4 associates with brain amyloid load differently in Hispanic and non‐Hispanic White (NHW) cohorts, we analyzed reported Centiloid values from studies that conducted amyloid positron emission ...

The impact of cognitive behavioral therapy for insomnia on cognitive performance and amyloid beta in older adults: A randomized controlled trial

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Insomnia is associated with increased risk for Alzheimer's disease (AD). It is unknown how cognitive behavioral therapy for insomnia (CBT‐I) impacts two hallmarks of AD progression, cognitive performance and beta‐amyloid (Aβ) burden.
