Dorso‐Ventral and Night‐Day Regulation of Extracellular K+ Dynamics in Mouse Hippocampal Astrocytes

Glia, Volume 74, Issue 9, September 2026.
Hippocampal astrocytic K+ buffering varies by region and time. Ventral astrocytes show faster K+ accumulation due to reduced Kir4.1 function. Such regional divergence is modulated by circadian shifts in Kir4.1 and gap junction coupling. ABSTRACT Astrocytes regulate extracellular potassium (K+) through multiple mechanisms operating across distinct ...

Self-Organizing Map for Blind Channel Equalization

Journal of information and communication convergence engineering, 2010
This paper is concerned with the use of a selforganizing map (SOM) to estimate the desired channel states of an unknown digital communication channel for blind equalization. The modification of SOM is accomplished by using the Bayesian likelihood fitness function and the relation between the desired channel states and channel output states.

Enduring autism‐like phenotypes and deregulated hypothalamic prosocial peptides after early‐life exposure to indoor flame retardants in male C57BL/6 mice

Journal of Neuroendocrinology, Volume 38, Issue 8, August 2026.
Abstract Polybrominated diphenyl ethers (PBDEs) are neuroendocrine‐disrupting chemicals that produce adverse neurodevelopmental effects. PBDEs have been implicated as risk factors for autism spectrum disorder (ASD), which is characterized by abnormal psychosocial functioning and is commonly comorbid with cognitive deficits and sensory abnormalities ...

Blind equalization criteria for MIMO-FIR channels driven by colored signal

Tongxin xuebao, 2012
In view of the statistic characteristics of the colored source,the law presented by the second and the fourth order correlative statistics of this kind of source is analyzed.A blind equalization criterion for MIMO-FIR channel was proposed,and the blind ...

Maximum-LikelihoodSemiblind Equalization of Doubly Selective Channels Using the EM Algorithm

EURASIP Journal on Advances in Signal Processing, 2010
Maximum-likelihood semi-blind joint channel estimation and equalization for doubly selective channels and single-carrier systems is proposed. We model the doubly selective channel as an FIR filter where each filter tap is modeled as a linear combination

The Mystery of Success: How Family Background Shapes Social Mobility

Review of Income and Wealth, Volume 72, Issue 3, August 2026.
ABSTRACT This study examines social mobility and its underlying drivers in Switzerland. We use a rich administrative dataset covering nearly 700,000 individuals across 23 birth cohorts. Rather than relying on traditional parent–child associations, we quantify the overall influence of familial factors, providing a wide‐ranging indicator of social ...

Moving Target Indication for Dual-Channel Circular SAR/GMTI Systems

Sensors, 2019
In a dual-channel circular synthetic aperture radar (CSAR) and ground moving target indication (GMTI) system, the antenna baseline is not parallel with the flight path due to a yaw angle.

Data-Aided Versus Blind Single-Carrier Coherent Receivers

IEEE Photonics Journal, 2010
Fiber-optic research in signal processing for the first generation of coherent communication systems was dominated by receivers with blind adaptation. Next-generation systems will require a scalable and modular design for higher order modulation formats.
