Compositional Time–Temperature–Transformation and Post‐Processing Window Mapping of Epoxy Nanocomposites via Machine Learning

open access: yesJournal of Applied Polymer Science, EarlyView.
Discrete DSC and rheological data are transformed into continuous compositional Time–temperature–transformation (TTT) diagrams through physics‐informed Gaussian Process Regression. The proposed framework quantitatively predicts post‐gel processing windows across temperature and nanofiller composition, providing a practical route for accelerated design ...

Resistance to Axial Traction Decreases Over Time Following Repaired Periportal Capsulotomies During Hip Arthroscopy

open access: yesArthroscopy, EarlyView.
Purpose To determine if distraction distance changes on an axial traction examination between the time zero capsular repair state and a later follow‐up traction examination in patients with staged bilateral hip arthroscopies for femoroacetabular impingement syndrome.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

open access: yesAnimal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Frequency Measurements of Superradiance from the Strontium Clock Transition

open access: yesPhysical Review X, 2018
We present the first characterization of the spectral properties of superradiant light emitted from the ultranarrow, 1-mHz-linewidth optical clock transition in an ensemble of cold ^{87}Sr atoms. Such a light source has been proposed as a next-generation

Photobiomodulation Enhances Tendon Regeneration: A Systematic Review and Meta‐analysis of Preclinical Studies

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate the preclinical evidence supporting the efficacy of photobiomodulation therapies in tendon regeneration. Methods A comprehensive literature search was conducted in MEDLINE, ScienceDirect, and Google Scholar to identify in vivo animal studies evaluating photobiomodulation therapies for tendon healing.

Frequency stability improvement for piezoresistive micromechanical oscillators via synchronization

open access: yesAIP Advances, 2017
Synchronization phenomenon first discovered in Huygens’ clock shows that the rhythms of oscillating objects can be adjusted via an interaction. Here we show that the frequency stability of a piezoresistive micromechanical oscillator can be enhanced via ...

Implementation of Allan Standard Deviation Technique in Stability Analysis of 4C31.61 Quasar Position

open access: yesJournal of Physics: Conference Series
Abstract The International Celestial Reference Frame (ICRF) plays an important role in astronomy and geodesy. The realization of ICRF is based on the position of thousands of quasars observed using the Very-Long Baseline Interferometry (VLBI) technique. Better quality of ICRF is achieved when the position of the quasars is stable.

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Atmospheric Timing Transfer Using a Femtosecond Frequency Comb

open access: yesIEEE Photonics Journal, 2010
We have experimentally demonstrated atmospheric transfer of microwave timing references using a femtosecond frequency comb. The excess timing jitter induced by the atmospheric propagation has been characterized, and evidence is provided to show that such
