Structure-based lead optimization to improve antiviral potency and ADMET properties of phenyl-1H-pyrrole-carboxamide entry inhibitors targeted to HIV-1 gp120
We are continuing our concerted effort to optimize our first lead entry antagonist, NBD-11021, which targets the Phe43 cavity of the HIV-1 envelope glycoprotein gp120, to improve antiviral potency and…

Power-grid controller anomaly detection with enhanced temporal deep learning
Controllers of security-critical cyber-physical systems, like the power grid, are a very important class of computer systems. Attacks against the control code of a power-grid system, especially zero-day attacks, can…

Evaluating Visual-Semantic Explanations using a Collaborative Image Guessing Game
Abstract While there have been many proposals on making AI algorithms explainable, few have attempted to evaluate the impact of AI-generated explanations on human performance in conducting human-AI collaborative tasks.…

Next-Generation Spray Delivery of Vaccines and Other Therapeutics with High Viscosity Aerosol
While conventional methods for spraying (Spray 1.0) such as pump sprays are largely viscosity-limited and only work for fluids with consistency close to water, the PARC technology called FEA, short…

Approaches to multi-domain language recognition
Approaches found to provide robustness in multi-domain LID include a domain-and-language-weighted Gaussian backend classifier, duration-aware calibration, and a source normalized multi-resolution neural network backend.

Estimation of Graphlet Counts in Massive Networks
In this work, we propose an unbiased graphlet estimation framework that is (a) fast with significant speedups compared to the state-of- the-art, (b) parallel with nearly linear-speedups, (c) accurate with
