Deep Neural Network-Based Interrupted Sampling Deceptive Jamming Countermeasure Method
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 With the development of digital radio frequency memory technology, the main-lobe deception jamming represented by interrupted-sampling repeater jamming (ISRJ) poses a severe challenge to radar. Traditional antijamming methods usually need to estimate the

Exploring Costa Rica's fungal trends: Insights from digitized specimens
PLANTS, PEOPLE, PLANET, EarlyView.Fungi are essential to tropical ecosystems but remain largely absent from conservation agendas. By analyzing over 78,000 fungal records from Costa Rica—a globally recognized biodiversity hotspot—this study reveals key patterns in fungal diversity, distribution, and seasonality.

Respirology, EarlyView.Pulmonary arterial baroreceptors reflexively stimulate sympathetic nerve activity (SNA) in response to elevated pulmonary artery pressure and distension. In pulmonary hypertension patients, changes in muscle SNA were proportional to changes in pulmonary haemodynamics following nebulised iloprost.

Rethinking Face‐to‐Face Interaction: Lessons from Studies of “Autistic Sociality”
Symbolic Interaction, EarlyView.Face‐to‐face interaction is a foundational concept in microsociology. This article surveys the social experiences of autistic people, who are commonly known for having a strained relationship with interactions face to face. By interpretively reviewing and synthesizing the broader literature on “autistic sociality,” the article provides a nuanced ...

Radar Range Deception with Time-Modulated Scatterers
, 2022 Modern radar systems are designed to have high Doppler tolerance to detect fast-moving targets. This means range and Doppler estimations are inevitably coupled, opening pathways to concealing objects by imprinting artificial Doppler signatures on the ...
