Distinguishing the causes of firing with themembrane potential slope
(2012)In this letter, we aim to measure the relative contribution of coincidence detection and temporal integration to the firing of spikes of a simple neuron model. To this end, we develop a method to infer the degree of synchrony ...

Effect of head posture on the healthy human carotid bifurcation hemodynamics
(2013)Head and neck postures may cause morphology changes to the geometry of the carotid bifurcation (CB) that alter the low and oscillating wall shear stress (WSS) regions previously reported as important in the development of ...

Induction of caspase-independent programmed cell death by vitamin E natural homologs and synthetic derivatives.
(2009)Current observations in the literature suggest that vitamin E may be a suitable candidate for cancer chemotherapy. To investigate this further, we examined the ability of the vitamin E natural homologs [alpha-, beta-, ...

Near real-time VOCs analysis using an aspiration ion mobility spectrometer
(2013)The ChemPro 100i chemical detector (aspiration-type ion mobility spectrometer) was used for the detection of selected volatile organic compounds known to be potential indicators of human presence. The targeted group of ...

Observation of the equilibrium CuB-CO complex and functional implications of the transient heme a3 propionates in cytochrome ba3-CO from Thermus thermophilus. Fourier transform infrared (FTIR) and time-resolved step-scan FTIR studies
(2002)We report the first evidence for the existence of the equilibrium CuB 1+-CO species of CO-bound reduced cytochrome ba3 from Thermus thermophilus at room temperature. The frequency of the C-O stretching mode of CuB 1+-CO ...

Permeation profiles of potential urine-borne biomarkers of human presence over brick and concrete
(2012)Headspace solid phase micro-extraction gas chromatography-mass spectrometry (SPME-GC-MS) analysis was performed over an in-house made filling chamber loaded with brick or concrete, mimicking a potential entrapment scene ...

Preliminary investigation of using volatile organic compounds from human expired air, blood and urine for locating entrapped people in earthquakes
(2005)A preliminary investigation on the possibility of using volatile organic compounds (VOCs) determination of expired air, blood and urine, for the early location of entrapped people in earthquakes, has been carried out. A ...

Probing the ligand recognition and discrimination environment of the globin-coupled oxygen sensor protein YddV by FTIR and time-resolved step-scan FTIR spectroscopy
(2015)YddV is a newly discovered signal transducer heme protein that recognizes O2 and CO. Structural differences in the ligand-bound heme complex in YddV reflect variations in catalytic regulation by O2 and CO. Time-resolved ...

Qualitative visual image analysis of bruise age determination: a survey.
(2006)The evaluation of bruise color imaging is a very important task in forensic medicine. However, there is no standardized methodology in carrying out this task. In this paper, an attempt was made to review the different ...

A spiking neuron model: Applications and learning
(2002)This paper presents a biologically inspired, hardware-realisable spiking neuron model, which we call the Temporal Noisy-Leaky Integrator (TNLI). The dynamic applications of the model as well as its applications in Computational ...

Trophoblast-specific gene manipulation using lentivirus-based vectors
(2007)The trophoblast layers of the mammalian placenta carry out many complex functions required to pattern the developing embryo and maintain its growth and survival in the uterine environment. Genetic disruption of many gene ...
