A transient PEMFC model with CO poisoning and mitigation by O2 bleeding and Ru-containing catalyst
, 2007 In this paper we present a transient, fully two-phase, non-isothermal model of carbon monoxide poisoning and oxygen bleeding in the membraneelectrode assembly of a polymer electrolyte fuel cell. The model includes a detailed description of mass, heat and

Autoregressive Perturbations for Data Poisoning [PDF]
arXiv, 2022 The prevalence of data scraping from social media as a means to obtain datasets has led to growing concerns regarding unauthorized use of data. Data poisoning attacks have been proposed as a bulwark against scraping, as they make data "unlearnable" by adding small, imperceptible perturbations.

Cardiac Organoid Model Inspired Micro‐Robot Smart Patch to Treat Myocardial Infarction
Advanced Materials, EarlyView.The heart organoid model exhibits the acidic microenvironment characteristic of myocardial infarction, which emerges as a pivotal force propelling the movement of micro‐robots. These micro‐robots, administered through microneedles, can penetrate deep into the tissue, effectively delivering therapeutic payloads to facilitate heart repair.

Model-Targeted Poisoning Attacks with Provable Convergence [PDF]
arXiv, 2020 In a poisoning attack, an adversary with control over a small fraction of the training data attempts to select that data in a way that induces a corrupted model that misbehaves in favor of the adversary. We consider poisoning attacks against convex machine learning models and propose an efficient poisoning attack designed to induce a specified model ...

Cu–Au nanoparticles produced by the aggregation of gas‐phase metal atoms for CO oxidation
Aggregate, Volume 3, Issue 6, December 2022., 2022 The aggregation of gas‐phase Cu and Au atoms into Cu–Au nanoparticles with non‐equilibrium structures and compositions is studied using molecular dynamics. Density functional calculations reveal the significant effect of the structure of the obtained realistic models of Cu–Au nanoparticles on their CO and O binding properties as well as their CO ...

Data Poisoning against Differentially-Private Learners: Attacks and Defenses [PDF]
arXiv, 2019 Data poisoning attacks aim to manipulate the model produced by a learning algorithm by adversarially modifying the training set. We consider differential privacy as a defensive measure against this type of attack. We show that such learners are resistant to data poisoning attacks when the adversary is only able to poison a small number of items ...
