This work presents a novel collection method for gunshot residues (GSR) using a sampling procedure based on ethylenediaminetetraacetic acid (EDTA) solution as a complexing agent on moistened swabs. Detection was via a sector-field inductively coupled plasma mass spectrometry (HRICP-MS). The proposed collection and analytical method allowed detection of antimony (Sb), barium (Ba) and lead (Pb) a...

Human physiological signals have been widely used to non‐invasively measure cognitive load (CL) during task execution. A major challenge for CL detection is the presence of stress, which may affect physiological measurements in ways that confound reliable detection of CL. In this experiment we investigated the effect of stress on cognitive load measurement using galvanic skin response (GSR) as ...

In this study, quantitative trait locus (QTL) analysis was used to identify candidate chromosomes and for detecting the regions that include the gene or genes causing gutter-shaped root (GSR) in AKXL recombinant inbred mouse strains. One potential QTL was detected on chromosome 5 within a region of 13.0 cM, where the likelihood ratio statistic (LRS) score was higher than a suggestive level. Thi...

The rapid growth of the availability of wearable biosensors has created the opportunity for using biological signals to measure worker performance. An important question is how to use such signals to not just measure, but actually predict worker performance on a task under stressful and potentially high risk conditions. Here we show that the biological signal known as galvanic skin response (GS...

The relation between performance and stress is described by the Yerkes-Dodson Law but varies significantly between individuals. This paper describes a method for determining the individual optimal performance as a function of physiological signals. The method is based on attention and reasoning tests of increasing complexity under monitoring of three physiological signals: Galvanic Skin Respons...

The effects of stress (threat of shock) on GSR nonspecific responses were evaluated for Ss who differed in transitory anxiety as measured by the Affect Adjective Check List (AACL). 52 Ss were equally divided among 4 groups: Hi AACL Stress, Lo AACL Stress, Hi AACL Nonstress, and Lo AACL Nonstress. First, all Ss rested; then both Stress groups were threatened with shock, while both Nonstress grou...

Imaging and analyzing gunshot residue (GSR) particles using the scanning electron microscope equipped with an energy dispersive X-ray spectrometer (SEM-EDS) is a standard technique that can provide important forensic evidence, but the discrimination power of this technique is limited due to low sensitivity to trace elements and difficulties in obtaining quantitative results from small particles...

The focus of our paper is to attempt to define a generative probabilistic topic model for text summarization that aims at extracting a small subset of sentences from the corpus with respect to some given query. We theorize that in addition to a bag of words, a document can also be viewed in a different manner. Words in a sentence always carry syntactic and semantic information and often such in...

Neuronal degeneration in multiple sclerosis has been linked to oxidative stress. Dimethyl fumarate (DMF) is an effective oral therapeutic option shown to reduce disease activity and progression in patients with relapsing-remitting multiple sclerosis. DMF activates the transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) leading to increased synthesis of the major cellular ant...
