The detection of unknown waveforms in ESM receivers: FFT-based real-time solutions [PDF]
, 2011 Radars and airborne electronic support measures (ESMs) systems are locked in a tactical battle to detect each other whilst remaining undetected. Traditionally, the ESM system has a range advantage.

The elimination of broker voting in director elections [PDF]
, 1980 In 2009, the Securities and Exchange Commission (SEC) reformed shareholder voting by eliminating uninstructed broker voting in director elections. We use this reform as a quasi-natural experiment to assess the value of shareholder empowerment.

CNS Neuroscience &Therapeutics, Volume 31, Issue 5, May 2025.NT5C2 and PRCP were identified as druggable targets for intracranial aneurysms (IA) with multiomic druggable genome‐wide Mendelian randomization, colocalization analysis, and external validation support. The causal effect of NT5C2 and PRCP on IA was independent of the modifiable IA risk factors, such as high blood pressure, smoking, and insomnia ...

Global Ecology and Biogeography, Volume 34, Issue 5, May 2025.ABSTRACT Aim Migratory birds are under threat by climate change. Successfully conserving them requires knowing which climatic factors drive changes in their migratory behaviour. Weather conditions may directly or indirectly affect the temporally disjointed life history stages of migratory birds, including the breeding, roosting and nonbreeding stages ...

IEEE 802.11ad-based Radar: An Approach to Joint Vehicular Communication-Radar System [PDF]
arXiv, 2017 Millimeter-wave (mmWave) radar is widely used in vehicles for applications such as adaptive cruise control and collision avoidance. In this paper, we propose an IEEE 802.11ad-based radar for long-range radar (LRR) applications at the 60 GHz unlicensed band.

Characteristics of Global Light Rain System From GPM/DPR Measurements
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 8, 28 April 2025.Abstract Understanding the microphysical and macrophysical characteristics of global light rain (0.2–2.5 mm/hr) is important for modeling the hydrological cycle and enhancing the cloud‐related parameterization in the numerical weather prediction (NWP) model.

Proof-of-principle experimental demonstration of quantum secure imaging based on quantum key distribution [PDF]
Chinese Physics B 28, 104203, 2019We present a quantum secure imaging (QSI) scheme based on the phase encoding and weak + vacuum decoy-state BB84 protocol of quantum key distribution (QKD). It allows us to implement a computational ghost imaging (CGI) system with more simplified equipment and reconstructed algorithms by using a digital micro-mirror device (DMD) to preset the specific ...

Generative Deep Synthesis of MIMO Sensing Waveforms with Desired Transmit Beampattern [PDF]
arXivThis paper develops a generative deep learning model for the synthesis of multiple-input multiple-output (MIMO) active sensing waveforms with desired properties, including constant modulus and a user-defined beampattern. The proposed approach is capable synthesizing unique phase codes of on-the-fly, which has the potential to reduce interference ...
