A New Signal Separation and Sampling Duration Estimation Method for ISRJ Based on FRFT and Hybrid Modality Fusion Network

Remote Sensing
Accurate estimation of Interrupted Sampling Repeater Jamming (ISRJ) sampling duration is essential for effective radar anti-jamming. However, in complex electromagnetic environments, the simultaneous presence of suppressive and deceptive jamming, coupled

Supporting Pathways into College and Careers: The Case of Adult Education ESL in Community Colleges

TESOL Quarterly, EarlyView.
Abstract Research has increasingly focused on the importance of college preparation and career and technical education (CTE) for multilingual learners (MLs), many of them classified as “English Learners,” in K‐12 schools. Less attention, however, has been paid to the collegiate and professional aspirations of another significant population of MLs in ...

A Scattering Feature-enhanced Network for SAR Deceptive Jamming Discrimination

Leida xuebao
Synthetic Aperture Radar (SAR) enables round-the-clock high-resolution imaging under all weather conditions, thereby playing a vital role in both military domains (e.g., surveillance, reconnaissance, air defense, and missile defense) and civilian domains

Erasure Insertion in RS-Coded SFH MFSK Subjected to Tone Jamming and Rayleigh Fading

, 2005
The achievable performance of Reed Solomon (RS) coded slow frequency hopping (SFH) assisted M-ary frequency shift keying (MFSK) using various erasure insertion (EI) schemes is investigated, when communicating over uncorrelated Rayleigh fading channels in

How Enrichment Aesthetic Shapes Zoo Visitor Perceptions of Chimpanzee Behavior and Conservation

Zoo Biology, EarlyView.
Enrichment aesthetic (natural vs non‐natural) does not impact visitor perceptions of chimpanzee behavior, conservation, or pet suitability. Most visitors associate chimpanzees with a conservation status of vulnerable, rather than endangered. ABSTRACT Public perceptions of chimpanzees (Pan troglodytes) are shaped by the context in which they are viewed.

SAR Jamming via Metasurface-Enabled Spatial-Block Subsection Shift-Frequency Modulation

Remote Sensing
Synthetic aperture radar (SAR) imaging is vulnerable to deceptive jamming, while conventional whole-aperture subsection shift-frequency modulation sequentially applies multiple frequency shifts in slow time, causing reduced temporal support for each ...

Proximate factors underpinning receiver responses to deceptive false alarm calls in wild tufted capuchin monkeys: is it counterdeception? [PDF]

, 2013
Previous research demonstrates that tufted capuchin monkeys use terrestrial predator alarm calls in a functionally deceptive manner to distract conspecifics when feeding on contestable resources, although the success of this tactic is limited because ...
