Human biomarker navigator

open access: yesiMeta, EarlyView.
The Human Biomarker Navigator integrates the disease continuum, biomarker dynamics, cross‐organ biomarker networks, biomarker classification, and technology‐driven paradigms. It maps how biomarkers link multi‐system physiology and pathology across the nervous, respiratory, endocrine, circulatory, immune, digestive, urinary, reproductive, and ...

SubDIVIDE: Efficient tensor‐valued diffusion magnetic resonance imaging via joint diffusional variance decomposition modeling and subspace reconstruction

open access: yesJournal of Intelligent Medicine, EarlyView.
SubDIVIDE integrates a physics‐consistent DIVIDE subspace directly into MRI reconstruction. By embedding a low‐rank basis derived from a large DIVIDE signal dictionary into a joint ADMM optimization—together with composite sensitivity maps that absorb inter‐b‐value phase errors—the framework recovers quantitative microstructural maps from highly ...

Stage‐Dependent Prognostic Value of the Joint MASLD–NAFLD Fibrosis Score Phenotype Across the Cardiovascular–Kidney–Metabolic Syndrome Continuum: A Retrospective NHANES Cohort Analysis, 1999–2018

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The cardiovascular–kidney–metabolic (CKM) framework and metabolic dysfunction–associated steatotic liver disease (MASLD) describe a shared clinical continuum, but the prognostic value of joint fatty liver index (FLI)–NAFLD fibrosis score (NFS) phenotypes across CKM stages is uncertain.

Spatially Uniform and Defect‐Tolerant Plasmonic Responses in 3D Printed Gold Nanoparticle Assemblies

open access: yesLaser &Photonics Reviews, EarlyView.
We introduce 3D nanoprinting of gold nanoparticle assemblies and show that their broad optical responses remain reproducible despite structural disorder. This robustness is attributed to ensemble‐averaged plasmonic responses from many local coupling regions.

Epi-convergence of lossy likelihoods

open access: yes, 2003
Given a sequence of observations (Xn)n≥1 and a family of probability distributions {Qθ}θ∈Θ, the lossy likelihood of a particular distribution Qθ given the data X n 1: = (X1,X2,...,Xn) is defined as Qθ(B(X n 1,D)), where B(X n 1,D) is the distortion-ball ...

Hyperhomocysteinemia and Vitamin B Deficiency as Potential Aggravating Factors in Huntington's Disease: A Prospective Monocentric Study

open access: yesMovement Disorders, EarlyView.
Abstract Background Although not confirmed, some studies have suggested that elevated homocysteine levels are common in patients with Huntington's disease (HD). Its clinical relevance remains unclear. Objectives We aimed to assess vitamin B and homocysteine levels in HD patients and explore the relationships among hyperhomocysteinemia, vitamin B ...

Improved Accuracy of Multidimensional Spatially‐Selective Saturation RF Pulses for Short‐Repetition‐Time Steady‐State Imaging

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To introduce and evaluate a novel RF pulse design algorithm for multi‐dimensional spatially tailored excitation that is optimized for spoiled steady‐state gradient echo MRI sequences. Methods Existing multi‐dimensional RF pulse design algorithms optimize RF and gradient waveforms using a loss function based on a single RF pulse ...

Iterative Navigator‐Based Retrospective Motion Correction for Multi‐Shot Brain MR Elastography and Evaluation of Single‐Shot Post‐Reconstruction Correction

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Brain MR elastography (MRE) is uniquely sensitive to subject motion, as even small phase deviations can produce large errors in the mechanical properties estimated. Existing motion correction strategies have not been validated for MRE and are often incompatible with complex multi‐shot or joint temporal reconstructions.
