Glymphatic dysfunction couples with cortical excitation–inhibition imbalance in epilepsy: Evidence from Rasmussen encephalitis

Epilepsia, EarlyView.
Cong Fu et al. demonstrate that glymphatic system dysfunction is linked to enhanced inhibitory cortical activity using diffusion MRI and EEG. These findings highlight a mechanistic link between perivascular fluid dynamics and neuronal activity, suggesting a role for glymphatic function in maintaining cortical stability in epilepsy.

Deep CNN-based detection of cardiac rhythm disorders using PPG signals from wearable devices.

PLoS ONE
Cardiac rhythm disorders can manifest in various ways, such as the heart rate being too fast (tachycardia) or too slow (bradycardia), irregular heartbeats (like atrial fibrillation-AF, ventricular fibrillation-VF), or the initiation of heartbeats in ...

Differential bandpass filters and differential diplexer for WLAN using LTCC

, 2007
在本論文提出應用於雙頻無線區域網路頻段差動帶通濾波器和差動雙工器之設計。假若在電路中使用平衡式架構，則可省去balun，且平衡式架構具有使用虛擬接地以改善較差的實際接地，並降低同模雜訊干擾等優點。差動帶通濾波器設計中，再加上兩個零點，可改善帶通濾波器的效能，另外在差動雙工器設計中，加入LC共振器，對於雙工器的兩個頻帶(2.4GHz和5.2GHz)可提供良好的隔離。 　　在設計新的帶通濾波器和雙工器中，採用LTCC (low-temperature co-fired ceramics)的製程 ...

CaMKIIβ insufficiency disrupts cortical networks, producing aberrant low‐gamma oscillations and seizure susceptibility

Epilepsia, EarlyView.
Abstract Objective Pathogenic variants in the calcium/calmodulin‐dependent protein kinase II B gene (CAMK2B) have been associated with neurodevelopmental disorders, including epilepsy, yet the mechanisms underlying cortical dysfunction remain largely unclear.

Complement C3 mediates adolescent social isolation‐induced hippocampal synaptic deficits and sex‐specific emotional dysfunction

Interdisciplinary Medicine, EarlyView.
Adolescent social isolation disrupts hippocampal function and exacerbates emotional symptoms, with sex‐specific patterns, as shown by human studies. In mice, social isolation decreased hippocampal synaptic density and calcium signaling, upregulated complement proteins, and activated complement‐mediated microglial synaptic phagocytosis.

Design of microstrip tri-mode balun bandpass filter with high selectivity

, 2015
A new microstrip tri-mode balun bandpass filter (BPF) with good filtertype and balun-type functions is presented. To realise the tri-mode BPF performance, the multimode stepped-impedance resonator is introduced and parallel coupled to both the balanced ...

Neurophysiological evidence for goal‐directed attentional control dysfunction in generalized anxiety disorder

Journal of Intelligent Medicine, EarlyView.
Abstract Attentional control theory posits that anxiety disrupts goal‐directed attentional system; however, its neurophysiological mechanisms in generalized anxiety disorder (GAD) remain unclear. This study investigated two core operations of the goal‐directed attentional system in GAD—inhibition and shifting—by characterizing their behavioral and ...

Compact differential bandpass filter using onesixth mode and novel onethird mode triangular SIW resonators

, 2018
In this letter, a novel one-third mode triangular substrate integrated waveguide resonator (OTMTSIWR) is presented firstly. Compared with the conventional OTMTSIWR, this novel resonator has a lower resonant frequency (f0) and acceptable unloaded quality (

Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator

Laser &Photonics Reviews, EarlyView.
This article demonstrates a record‐breaking microwave frequency comb generator using an ultrahigh‐harmonic‐order mode‐locked optoelectronic oscillator. By integrating dual recirculating loops into a low‐coherence system, the researchers achieved a harmonic order of 956 with superior noise suppression.
