Power Allocation in Nonselfish Symbiotic Cognitive Relaying with Partial Channel State Information

International Journal of Distributed Sensor Networks, 2014
We first address the problem of power allocation at cognitive users (CUs) to maximize the throughput of a nonselfish symbiotic cognitive radio scheme, in which the CUs may assist the data transmission of primary users (PUs) via nonorthogonal amplify-and ...

Activism risk and corporate self‐regulation: Investigating how anti‐SLAPP laws impact firms' institutional corporate social performance

Strategic Management Journal, Volume 47, Issue 3, Page 831-859, March 2026.
Abstract Research Summary This research investigates how firms attempt to preempt activism before it mobilizes into an active threat. Employing a difference‐in‐differences design, we examine the quasi‐exogenous enactments of laws that prevent Strategic Lawsuits Against Public Participation (anti‐SLAPP laws) in the United States.

Channel-Prediction-Driven Rate Control for LDPC Coding in a Fading FSO Channel With Delayed Feedback

IEEE Open Journal of the Communications Society
Rate-adaptive coding enables reliable communication while efficiently utilizing the available channel mutual information in free-space optical (FSO) communication. While adaptive coding has been explored in numerous articles, the effect of feedback delay

Model Validation of M‐I Coupling in SWMF

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The accurate modeling of field‐aligned currents (FAC) and electron precipitation is critical for understanding magnetosphere‐ionosphere coupling and improving space weather predictions. This study evaluates the performance of the SWMF in replicating observed FAC magnitudes and distributions, as well as electron precipitation during storms and ...

Modeling the Impact of Initiation Parameters on the Dynamics of the 2012 Te Maari Laterally Confined Debris Avalanche

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Volcanic debris avalanches can transform into highly mobile debris flows, reaching long runout distances and posing significant hazards to downstream populations. This high mobility arises from complex, evolving rheological behavior driven by dynamic changes in pore pressure, internal resistance, and material properties during the flow.

TypeII-CsiNet: CSI Feedback with TypeII Codebook

ICC 2024 - IEEE International Conference on Communications
The latest TypeII codebook selects partial strongest angular-delay ports for the feedback of downlink channel state information (CSI), whereas its performance is limited due to the deficiency of utilizing the correlations among the port coefficients. To tackle this issue, we propose a tailored autoencoder named TypeII-CsiNet to effectively integrate ...

Harnessing Deep Learning for Dual Gains in S2S‐Scale Soil Moisture Forecasting and Flash Drought Mechanisms

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Flash drought (FD), so‐named for its abrupt and unforeseen onset, poses a significant challenge to forecasting, as current Numerical Weather Prediction (NWP) shows limited skill in the sub‐seasonal to seasonal timescale (S2S, 2‐week to 2‐month range).

Cross‐Cultural Adaptation and Psychometric Evaluation of the Korean Version of Crisis Self‐Efficacy Index

Journal of Contingencies and Crisis Management, Volume 34, Issue 1, March 2026.
ABSTRACT Crisis self‐efficacy reflects individuals' beliefs in their ability to manage crises and plays a crucial role in shaping responses during emergency situations. To support crisis preparedness in South Korea, a validated instrument for assessing self‐efficacy in crisis contexts is required.
