Anti-interrupted-sampling repeater jamming method based on frequency agility waveform and sparse recovery

EURASIP Journal on Advances in Signal Processing
Interrupted-sampling repeater jamming (ISRJ) is a type of intra-pulse coherent jamming that poses a significant threat to radar detection and tracking of targets. This paper proposes an ISRJ suppression method based on frequency agile waveform and sparse

Interrupted-Sampling Repeater Jamming Suppression Based on Stacked Bidirectional Gated Recurrent Unit Network and Infinite Training

IEEE Access, 2019
Interrupted-sampling repeater jamming (ISRJ) is coherent jamming based on digital radio frequency memory (DRFM) device, which repeatedly samples, stores, modulates, and retransmits part of the radar emitted signal, and flexibly forms false targets in the

Predicting Learning: Understanding the Role of Executive Functions in Children's Belief Revision Using Bayesian Models

Topics in Cognitive Science, EarlyView.
Abstract Recent studies suggest that learners who are asked to predict the outcome of an event learn more than learners who are asked to evaluate it retrospectively or not at all. One possible explanation for this “prediction boost” is that it helps learners engage metacognitive reasoning skills that may not be spontaneously leveraged, especially for ...

Sub-band Contrast and Entropy of SAR Images: Concepts and Applications to Interference Detection and Suppression

Leida xuebao
Spaceborne Synthetic Aperture Radar (SAR) data may be prone to interrupted-sampling repeater jamming and many common unintentional interferences, such as linear frequency modulated pulses.

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

Leg‐fidgeting versus standing breaks during prolonged sitting: Impacts on blood pressure and heart rate in young women

Experimental Physiology, EarlyView.
Abstract The objective of this work was to examine whether leg‐fidgeting breaks during prolonged sitting could be a practical alternative to standing breaks in preventing blood pressure (BP) and heart rate (HR) impairments. Young women (n = 16; age = 21.9 ± 3.0 years; body mass index = 21.1 ± 4.9 kg/m2) completed three 3‐h prolonged sitting conditions ...

The effects of uninterrupted and interrupted sitting on blood pressure and arterial stiffness in patients with established coronary heart disease

Experimental Physiology, EarlyView.
Abstract Sedentary behaviour is an independent risk factor for cardiovascular disease. In healthy adults, prolonged uninterrupted sitting acutely increases blood pressure (BP) and aortic stiffness; however, these effects can be mitigated with light physical activity interruptions.
