Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

Advanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Single‐cell atlas of neuroglial dynamics in SNCA‐A53T Parkinson's disease mouse model

Animal Models and Experimental Medicine, EarlyView.
We performed single‐cell RNA sequencing of midbrain and striatal tissues from SNCA‐A53T Parkinson's disease (PD) mice, revealing glia‐enriched PD‐risk gene signatures and disease‐specific subpopulations. Transcriptional dysregulation of key TFs (e.g., Rorb, Foxc1) and enhanced neuroinflammatory signaling (SEMA, CCL, MIF) were identified.

SnRNA‐seq reveals cellular heterogeneity and proliferation mechanisms in limb venous malformations

Animal Models and Experimental Medicine, EarlyView.
To dissect the cellular heterogeneity and invasive mechanisms of limb venous malformations (VMs), this study first obtained tissue samples from four patients with VMs and four normal controls (NC). Single‐nucleus suspension was prepared, followed by transcriptome library construction and sequencing. After pretreatment, quality control, standardization,

Default Effect in ESG Investment: When a Recommendation Goes a Long Way

Business Strategy and the Environment, EarlyView.
ABSTRACT Individual investors display a positive attitude toward ESG investments but typically fail to act upon it. We report results from a preregistered online experiment testing a default option on 1050 US investors examining the mechanisms driving the effectiveness of default options in promoting ESG investments.

An Adaptive Segmental Model for Accurate Signal Propagation and RSS Prediction

International Journal of Antennas and Propagation
Received signal strength (RSS) is a key metric for assessing the strength of a received signal. However, indoor signal stability is affected by multiple factors, leading to RSS fluctuations even at fixed locations.
