Resveratrol, a natural product derived from grapes, is a phytoalexin with antioxidative activity. In this work we present initial results of an ongoing study of the geometry of the ground state and of the first two (singlet and triplet) excited states of resveratrol and the structurally related compounds diethyl-stilbestrol-stilbene and trans-stilbene. The molecular geometries were optimized bo...

We present a new model for acquiring comprehensive multiword lexicons from large corpora based on competition among n-gram candidates. In contrast to the standard approach of simple ranking by association measure, in our model n-grams are arranged in a lattice structure based on subsumption and overlap relationships, with nodes inhibiting other nodes in their vicinity when they are selected as ...

In this article, we present coherent control of above-threshold photoemission from a tungsten nanotip achieving nearly perfect modulation. Depending on the pulse delay between fundamental ([Formula: see text]) and second harmonic ([Formula: see text]) pulses of a femtosecond fiber laser at the nanotip, electron emission is significantly enhanced or depressed during temporal overlap. Electron em...

Extractive methods for multi-document summarization are mainly governed by information overlap, coherence, and content constraints. We present an unsupervised probabilistic approach to model the hidden abstract concepts across documents as well as the correlation between these concepts, to generate topically coherent and non-redundant summaries. Based on human evaluations our models generate su...

Intrinsically disordered proteins carry out many important functions in the cell. However, the lack of an ordered structure causes dramatic signal overlap and complicates the NMR-based characterization of their structure and dynamics. Here we demonstrate that the resonance assignment of 441-residue Tau and its smaller isoforms, htau24 (383 residues) and htau23 (352 residues), three prototypes o...

We present a method to address the challenging problem of segmentation of multi-modality isointense infant brain MR images into white matter (WM), gray matter (GM), and cerebrospinal fluid (CSF). Our method is based on contextguided, multi-stream fully convolutional networks (FCN), which after training, can directly map a whole volumetric data to its volume-wise labels. In order to alleviate th...

This paper presents a fast method for computing whether or not two convex polygons in three dimensions intersect. The test relies exclusively on the sign of 4 4 determinants. The source code is available online.

Some techniques which average multiple AMSR satellite data passes into daily sets create images with diminished temporal resolution. This results from averaging data of multiple overlapping passes separated by many hours. Overlap can be reduced by instead grouping data according to local time of day. This new method maximizes temporal resolution by decreasing both the number and the temporal va...

Phonological priming between spoken words was examined using CVCVC bisyllabic pseudoword primes and word or pseudoword targets. The influence of different types of overlap was compared, prime and target sharing the coda, the rime or the final syllable. The task was target shadowing. Two priming conditions were used, the auditory targets being preceded by auditory primes in unimodal and by visua...
