Poisons that are learned faster are more effective [PDF]
arXiv, 2022 Imperceptible poisoning attacks on entire datasets have recently been touted as methods for protecting data privacy. However, among a number of defenses preventing the practical use of these techniques, early-stopping stands out as a simple, yet effective defense.

Caribbean slavery, British abolition and the cultural politics of venereal disease in the Atlantic world [PDF]
, 2012 Venereal disease was commonplace among free and enslaved populations in colonial Caribbean societies. This article considers how contemporaries (both in the empire and metropole) viewed venereal infection and how they associated it with gendered notions ...

Electrochemical Fabrication of Nanoparticles and Single‐Atom Catalysts via Cathodic Corrosion
Chemistry – A European Journal, EarlyView.While cathodic corrosion can be detrimental to electrode surfaces, it has emerged as a powerful electrochemical method for fabricating nanoparticles and single‐atom catalysts from bulk wires. This mini‐review highlights recent advancements in cathodic corrosion‐based synthesis, focusing on its unique capabilities and the superior (photo ...

Mercury's Protoplanetary Mass [PDF]
arXiv, 2004 Major element fractionation among chondrites has been discussed for decades as ratios relative to Si or Mg. Recently, by expressing ratios relative to Fe, I discovered a new relationship admitting the possibility that ordinary chondrite meteorites are derived from two components, a relatively oxidized and undifferentiated, primitive component and a ...

Detecting Backdoor Poisoning Attacks on Deep Neural Networks by Heatmap Clustering [PDF]
arXiv, 2022 Predicitions made by neural networks can be fraudulently altered by so-called poisoning attacks. A special case are backdoor poisoning attacks. We study suitable detection methods and introduce a new method called Heatmap Clustering. There, we apply a $k$-means clustering algorithm on heatmaps produced by the state-of-the-art explainable AI method ...

Chemistry–Methods, EarlyView.In‐situ/operando characterization techniques have been improved rapidly under the need to observe the changes on catalytic materials in operational conditions. This perspective highlights the recent works on applying in‐situ/operando analysis to electrocatalysts for CO2 reduction reaction and water splitting. Abstract The transition to a carbon‐neutral

FRIB: Low-poisoning Rate Invisible Backdoor Attack based on Feature Repair [PDF]
arXiv, 2022 During the generation of invisible backdoor attack poisoned data, the feature space transformation operation tends to cause the loss of some poisoned features and weakens the mapping relationship between source images with triggers and target labels, resulting in the need for a higher poisoning rate to achieve the corresponding backdoor attack success ...

Chemistry–Methods, EarlyView.A new methodology is presented to study the kinetics of the galvanic replacement reaction between silver and gold, allowing, for the first time to our knowledge, real‐time monitoring of the dynamics of this redox reaction by quantifying the main driving force, that is, the time‐ and concentration‐dependent redox potential, which cannot be captured by ...
