Validation of PHAST Dispersion Model as Required for Usa Lng Siting Applications

open access: yesChemical Engineering Transactions, 2013
PHMSA in consultation with FERC issued guidance relating to approval in the USA of atmospheric dispersion models for LNG siting applications. This guidance includes a Model Evaluation Protocol (MEP), and an associated experimental database against which ...

PHast -- Perfect Hashing made fast [PDF]

open access: green
Perfect hash functions give unique "names" to arbitrary keys requiring only a few bits per key. This is an essential building block in applications like static hash tables, databases, or bioinformatics. This paper introduces the PHast approach that combines the fastest available queries, very fast construction, and good space consumption (below 2 bits ...

PhAST: pharmacophore alignment search tool [PDF]

open access: yesChemistry Central Journal, 2009
We developed the Pharmacophore Alignment Search Tool (PhAST), a text-based technique for rapid hit and lead structure searching in large compound databases. For each molecule, a two-dimensional graph of potential pharmacophoric points (PPPs) is created, which has an identical topology as the original molecule with implicit hydrogen atoms.

Nucleosome assembly and disassembly pathways in vitro.

open access: yesPLoS ONE, 2022
Structural fluctuations of nucleosomes modulate the access to internal DNA in eukaryotic cells; clearly characterisation of this fundamental process is crucial to understanding gene regulation.

Consequence modeling for chlorine release of a storage tank with the field experiment data [PDF]

open access: yesمجله مدل سازی در مهندسی, 2014
Chlorine and its compounds are widely used in industries and they are needed to produce lots of materials. This element that is abundant in the Earth’s crust and oceans, the powerful, corrosive substance is considered essential to an array of products.

Live Longer through PHAsting [PDF]

open access: yesCell Metabolism, 2007
Dietary restriction provides considerable health benefits and may even increase life span in humans. Panowski et al. (2007) have now identified PHA-4/FoxA as an essential and specific component of DR-induced life-span extension in C. elegans.

Neurobiological Basis of Aversion-Resistant Ethanol Seeking in C. elegans

open access: yesMetabolites, 2022
Persistent alcohol seeking despite the risk of aversive consequences is a crucial characteristic of alcohol use disorders (AUDs). Therefore, an improved understanding of the molecular basis of alcohol seeking despite aversive stimuli or punishment in ...

PhAST: Pharmacophore alignment search tool [PDF]

open access: yesJournal of Computational Chemistry, 2008
AbstractWe present a ligand‐based virtual screening technique (PhAST) for rapid hit and lead structure searching in large compound databases. Molecules are represented as strings encoding the distribution of pharmacophoric features on the molecular graph.
