Chronic Arsenic Toxicity from Drinking Well Water in a Rural Area [PDF]
Iranian Journal of Toxicology, 2017 Background: Drinking water is the most important cause of poisoning in the world. Iran is one of the countries with arsenic-contaminated water upper limit of normal.

Molecules, 2022 Arsenic (As) is one of the most important toxic elements in the natural environment. Currently, although the assessment of the potential health risks of chronic arsenic poisoning has received great attention, the research on the effects of arsenic on the

Accumulative Poisoning Attacks on Real-time Data [PDF]
arXiv, 2021 Collecting training data from untrusted sources exposes machine learning services to poisoning adversaries, who maliciously manipulate training data to degrade the model accuracy. When trained on offline datasets, poisoning adversaries have to inject the poisoned data in advance before training, and the order of feeding these poisoned batches into the ...

What Distributions are Robust to Indiscriminate Poisoning Attacks for Linear Learners? [PDF]
arXiv, 2023 We study indiscriminate poisoning for linear learners where an adversary injects a few crafted examples into the training data with the goal of forcing the induced model to incur higher test error. Inspired by the observation that linear learners on some datasets are able to resist the best known attacks even without any defenses, we further ...

Poison Attacks against Text Datasets with Conditional Adversarially Regularized Autoencoder [PDF]
arXiv, 2020 This paper demonstrates a fatal vulnerability in natural language inference (NLI) and text classification systems. More concretely, we present a 'backdoor poisoning' attack on NLP models. Our poisoning attack utilizes conditional adversarially regularized autoencoder (CARA) to generate poisoned training samples by poison injection in latent space. Just

A Proposal to Measure the Quasiparticle Poisoning Time of Majorana Bound States [PDF]
Phys. Rev. B 89, 140505 (2014), 2013 We propose a method of measuring the fermion parity lifetime of Majorana fermion modes due to quasiparticle poisoning. We model quasiparticle poisoning by coupling the Majorana modes to electron reservoirs, explicitly breaking parity conservation in the system. This poisoning broadens and shortens the resonance peak associated with Majorana modes. In a

Nano Select, EarlyView.The graphical abstract represents fish scales, a waste by product, were repurposed as a bio‐adsorbent for Cr(III) and Co(II) removal. The scales were washed, dried, and ground before being tested under varying concentrations. FTIR analysis showed changes in functional groups after adsorption, while SEM revealed metal ion attachment.
