Exploiting the Sensitivity of $L_2$ Adversarial Examples to Erase-and-Restore [PDF]
arXiv, 2020 By adding carefully crafted perturbations to input images, adversarial examples (AEs) can be generated to mislead neural-network-based image classifiers. $L_2$ adversarial perturbations by Carlini and Wagner (CW) are among the most effective but difficult-to-detect attacks.

Search for gamma-ray emission from AE Aquarii with seven years of FERMI-LAT observations [PDF]
, 2016 AE Aquarii (AE Aqr) is a cataclysmic binary hosting one of the fastest rotating (P$_{\rm spin}$ = 33.08 s) white dwarfs known. Based on seven years of Fermi Large Area Telescope (LAT) Pass 8 data, we report on a deep search for gamma-ray emission from AE Aqr.

Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties
Advanced Functional Materials, EarlyView.This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...

Advanced Functional Materials, EarlyView.Spinal cord injury (SCI) poses significant challenges for regeneration due to a series of secondary injury mechanisms. How to use biomaterial approach to target the failed regeneration after SCI remains a critical challenge. This review systematically evaluates current strategies to optimize biomaterial topographies for neurite outgrowth, axonal ...

Sustainable trophy hunting and the conservation of alpine ungulates in Pakistan
Pirineos: Revista de Ecología de Montaña, 2002 [fr] Au nord du Pakistan, les ongulés alpins se distribuent dans des habitats diversifiés mais leur nombre a diminué ces dernières décades, peut-être du fait du braconnage et de la dégradation de l'habitat par les troupeaux domestiques.

Advanced Functional Materials, EarlyView.Janus (MoS2) transistors functionalized with sodium alginate (SA) and poly(vinylidene fluoride‐co‐trifluoroethylene) [P(VDF‐TrFE)] exhibit persistent photo‐induced ionic gating, driven by dynamic cation migration at the hybrid interface. This ionic mechanism enables finely tunable photoconductivity and emulates key synaptic plasticity behaviors ...

, 2009 We explore ways to reduce the number of bit operations required to implement AES. One way involves optimizing the composite field approach for entire rounds of AES. Another way is integrating the Galois multiplications of MixColumns with the linear transformations of the S-box.

Tattoo Assisted Optical Sensor System for Multimodal Discrete Physiological Sensing
Advanced Healthcare Materials, EarlyView.Conventional temporary tattoos can be used for improving the speckle imaging signal‐to‐noise ratio and stability of the specifically developed device for capturing skin motion related to physiological activities beneath the skin. This allows for sensing multimodal electrophysiological signals and physiological events from the skin consistent with ...
