Fiber Break Prevention Using Machine Learning Approaches

open access: yesJournal of Informatics and Web Engineering
Modern fiber-optic communication systems are built around optical fiber, which allows data to be sent by emitting infrared light pulses. It is widely used by telecommunications firms and is essential to the smooth transmission of information in internet

Nitric Oxide Intensification Associated With STEVE: TIMED/SABER‐REGO Observations and Comparison With GITM Simulation

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract Strong Thermal Emission Velocity Enhancement (STEVE) is a nightsky optical phenomenon of great research interest in recent years. STEVE is recognized to be co‐located with a latitudinally narrow channel of fast westward ion drifts, also known as “subauroral ion drifts” (SAID).

Influence of Solar Sails on Magnetic Field Measurements in Space Plasmas

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Solar sail technology is ready to be deployed in a satellite mission carrying a science‐grade magnetometer. In preparation for such a mission, it is essential to characterize the interactions between the sail and the ambient plasma that could affect the magnetometer readings.

Generalized Bandpass Sampling Receivers for Software Defined Radio

open access: yes, 2006
Based on different sampling theorem, for example classic Shannon’s sampling theorem and Papoulis’ generalized sampling theorem, signals are processed by the sampling devices without loss of information.

Orthotopic Esophageal Cancer Xenograft Model in Immunosuppressed Microminipigs for Near‐Infrared Fluorescence Endoscopy

open access: yesCancer Science, Volume 117, Issue 6, Page 1678-1689, June 2026.
We report the first successful orthotopic engraftment of human esophageal squamous cell carcinoma in immunosuppressed microminipigs and demonstrate high‐contrast near‐infrared fluorescence endoscopic detection using EGFR‐targeted cetuximab. This large‐animal model bridges preclinical imaging research and future clinical translation in esophageal cancer.

The Effects of Different Attentional Focus During Walking on Prefrontal Cortical Activation in Young Healthy Adults

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 11, June 2026.
Dual‐task walking did not significantly modulate dorsolateral prefrontal cortex activation, although a left‐lateralized pattern was observed. Gait performance (speed, cadence and stride length) remained comparable between single‐task and external attention conditions, while divided attention impaired gait parameters. Notably, internal attention reduces

Spatial frequency decomposition with bandpass filters for multiscale analyses and functional correlations

open access: yes
To address the essential problem in surface metrology of establishing functional correlations spatial, frequencies in topographic measurements are progressively decomposed into a large number of narrow bands.

Multifiber Array‐Based Photometry System for Multiregional Functional Mapping in the Mouse Brain

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 12, June 2026.
Existing fiber photometry approaches suffer from invasiveness and limited scalability. A newly developed multifiber array‐based photometry system allows targeting multiple brain regions with less invasiveness. The system was validated in two jGCaMP8s‐expressing mouse lines by monitoring GABAergic neural population activity across multiple brain regions

Phosphinate or Urea? Synthesis and Biological Evaluation of Prostate Specific Membrane Antigen‐Targeted Fluorophores With Different Zinc‐Binding Motif

open access: yesChemMedChem, Volume 21, Issue 10, 27 May 2026.
A comparison of two structurally related prostate specific membrane antigen (PSMA)‐targeted fluorophores revealed that the substitution of the urea motif lysine‐urea‐glutamate (KuE) by a phosphinate leads to probes with low nanomolar PSMA‐affinity, good and specific tumor uptake, and low off‐target tissue retention in mice.

Mismatch Insensitive Double-Sampling Quadrature Bandpass 61 Modulation

open access: yes, 2008
—In a double-sampling quadrature bandpass sigma– delta modulator, path mismatch between the double-sampling branches and between the I/Q paths occurs.
