Article Abstract
ϕ-OTDR perturbation detection applications demand optimal precision of the perturbation location. Strategies for improving both signal-to-noise (SNR) and precision of the perturbation location in a laboratory environment may fail when applying to a very long fiber under test (FUT) in real-field environments. With this deployment, meaningful energy points representing the response of a certain perturbation can be located at random locations of the fiber other than the original location of the perturbation. These random locations are referred to as the ghost energy points that confuse the system to mistakenly consider the location of these points as the original perturbation location. We present in this paper a novel space-time scanning (ST-scan) method that segregates the ghost energy point locations from those of the real perturbation so that the original perturbation location estimation is improved.

Prenatal alcohol exposure perturbs the development of radial glial cells in the fetal olfactory bulb.
Alcohol Clin Exp Res (Hoboken)
September 2025
Department of Neuroscience and Experimental Therapeutics, Penn State College of Medicine, Hershey, Pennsylvania, USA.
Background: Prenatal alcohol exposure (PAE) causes fetal alcohol spectrum disorder (FASD) and is associated with various cognitive and sensory impairments, including olfactory dysfunction. While both genetic and environmental factors contribute to olfactory dysfunction, PAE is considered a significant factor affecting brain development, including the olfactory system. In this study, we investigated the impact of PAE on the developing olfactory bulb (OB), specifically focusing on OB RGCs-radial glial cells that give rise to OB projection neurons.

September 2025
Department of Electronics and Communication Engineering, National Institute of Technology Patna, Patna, Bihar, India.
Context: This study investigates the radiation tolerance of a SiGe source vertical tunnel field effect transistor (VTFET) under heavy ion-induced single event effects (SEEs). Single event effects (SEEs) occur when high-energy particles interact with semiconductor devices, leading to unintended behavior. The effect of high energy ions on the VTFET is examined for various linear energy transfer (LET) values and at multiple ion hit locations.

Purpose: To describe the mechanisms, situational patterns, biomechanics and neurocognitive errors related ankle sprain injuries of professional male football players during match play.
Methods: There were 166 consecutive ankle sprain injuries identified occurring during official matches in players of top European football leagues. One hundred and forty (84%) injury videos were analysed for mechanism and situational pattern, with biomechanics on 20 players.
Abnormal theta- and gamma-band cortical activities during visuospatial attention in idiopathic REM sleep behavior disorder patients.
Biomed Eng Lett
September 2025
Department of Biomedical Engineering, College of Health Science, Yonsei University, Wonju, South Korea.
Unlabelled: Purpose: Idiopathic rapid eye movement (REM) sleep behavior disorder (iRBD) is a sleep disorder considered to be a prodromal stage of neurodegeneration disease and is often accompanied by cognitive impairments. The purpose of this study was to investigate spatiotemporal characteristics of abnormal oscillatory cortical activity associated with dysfunction of visuospatial attention in iRBD based on an explainable machine learning approach. Methods: EEGs were recorded from 49 iRBD patients and 49 normal controls while they were performing Posner's cueing task and transformed to cortical current density time-series.

Maintaining the epigenetic identity of centromeres is essential to prevent genome instability. Centromeres are epigenetically defined by the histone H3 variant CENP-A. Prior work in human centromeres has shown that CENP-A is associated with regions of hypomethylated DNA located within large arrays of hypermethylated repeats, but the functional importance of these DNA methylation (DNAme) patterns remains poorly understood.
