Detecting the sensitive area of evaporation duct and evaluating its impact on forecasts of electromagnetic propagation over the South China Sea

open access: yesFrontiers in Marine Science
Evaporation ducts can significantly modify the atmospheric refractive index profile, leading to errors in electromagnetic (EM) propagation prediction, thereby affecting the reliability of maritime radio communication and radar detection.

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

open access: yesBiological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Channel model for the surface ducts: Large-scale path-loss, delay spread, and AOA

open access: yes, 2015
Atmospheric ducts, which are caused by the rapid decrease in the refractive index of the lower atmosphere, can trap the propagating signals. The trapping effects of the atmospheric ducts can be utilized as a communication medium for beyond-line-of-sight (

Riding on a Pegasus: Is ‘Sustainability’ Still a Myth in Bangladesh's RMG Sector?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Although a growing number of studies explore sustainability, the role of stakeholders and institutions in shaping environmental sustainability initiatives remains overlooked particularly from the upstream fashion supply chain contexts. Drawing upon the framework proposed by Lee, our study aims to fill this gap by examining the interplay ...

Bridging Anatomy Curricular Gaps: Leveraging Student‐Created Video Resources in Elective Courses

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Traditional anatomical donor‐based dissection has long served as the cornerstone of anatomical education. However, with increasingly condensed curricula and diverse student learning preferences, multimedia tools have become vital adjuncts to support engagement, comprehension, and accessibility. At the Carle Illinois College of Medicine (CI MED)

IPILT–OHPL: An Over-the-Horizon Propagation Loss Prediction Model Established by Incorporating Prior Information Into the LSTM–Transformer Structure

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The evaporation duct is a prevalent atmospheric structure in the marine lower troposphere with significant regional nonuniformity. This structure can trap radio waves inside its layer and enable them to propagate over the horizon with less loss ...
