Femtosecond‐Laser‐Inscribed Cladding Fiber Bragg Gratings: Architectures, Design Trade‐Offs and Future Sensing Opportunities

open access: yesLaser &Photonics Reviews, EarlyView.
Femtosecond‐laser inscription enables precise positioning of fiber Bragg gratings within the cladding, introducing new spatial and modal design freedoms. Auxiliary‐waveguide, near‐core evanescent‐field, and direct cladding‐mode‐excitation architectures provide complementary pathways toward multiparameter, vector, distributed, and environmentally ...

Digital Printing of Photoreversible Protective Films

open access: yesMacromolecular Rapid Communications, EarlyView.
A photopolymerized and photoreversible temporary protective film based on an ortho‐nitrobenzyl crosslinker is presented that can be applied using aerosol jet printing. To improve adhesion to industry‐relevant surfaces, a polyethyleneimine‐based adhesion promoter was added to the aqueous formulation of diacrylate cross‐linker and acrylated macromers ...

Sheath-Preserving Complete Optic Nerve Avulsion Following Closed-Globe Injury: A Case Report

open access: yes, 1994
A 29-year-old man presented with a sudden loss of vision after a closed-globe injury. At presentation, he had no light perception in the right eye and the right pupil was dilated and nonreactive to light.

Proteoforms in Disease: Biomedical Applications of Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The proteome is a dynamic landscape of proteoforms arising from genetic mutations, alternative splicing, and post‐translational modifications (PTMs), which collectively drive biological function and disease phenotypes. Mass spectrometry (MS)‐based proteomics has emerged as an essential technique for elucidating this molecular complexity ...

Predicting Mesoscopic Larmor Frequency Shifts in Ex Vivo Porcine Optic Nerve

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Larmor frequency shifts in white matter (WM) vary with fiber orientation due to anisotropic microstructure. Since clinical voxels are significantly larger than these microscopic frequency variations, the measured signal represents a bulk average of local shifts.

Evaluating the effect of caudal epidural block on optic nerve sheath diameter in pediatric patients: randomized controlled study

open access: yesBMC Anesthesiology
Introduction Caudal epidural block is a widely performed procedure for postoperative pain control of pediatric patients. As the local anesthetic acts by spreading cranially after caudal block, it may lead to several effects on the cerebrospinal fluid and

Optic Nerve Sonography in the Diagnostic Evaluation of Pseudopapilledema and Raised Intracranial Pressure: A Cross-Sectional Study

open access: yesNeurology Research International, 2015
Introduction. Differentiating pseudopapilledema from papilledema which is optic disk edema and a result of increased ICP (intracranial pressure) is important and can be done with noninvasive methods like orbital ultrasound examination. Method. This was a

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...
