Oxidative stress leads to the activation of the Nuclear factor-erythroid-2-related factor 2 (Nrf2) pathway. While most studies have focused on the activation of the Nrf2 pathway after single chemical treatment, little is known about the dynamic regulation of the Nrf2 pathway in the context of repeated exposure scenarios. Here we employed single...

Het wereldwijde klimaat en dus ook het klimaat in Nederland verandert. De Nationale Adaptatiestrategie (NAS) van het ministerie van Infrastructuur en Milieu vraagt om een breder inzicht in de risicofactoren voor Nederland als gevolg van de voorziene klimaatverandering. Onze energie-, transport-, informatie- en communicatietechnologie (ICT) - en...

The current medical countermeasures for organophosphate (OP) poisoning are effective to a reasonable extent, yet, there is room for improvement. In this review, suspected causes of acute and long term-effects of OPexposure and possible interventions will be discussed, in relation to the type of nerve agent and different exposure routes....

Using staff personnel for playing roles in simulation-based training (e.g. team mates, adversaries) elevates costs, and imposes organizational constraints on delivery of training. One solution to this problem is to use intelligent software agents that play the required roles autonomously. BDI modeling is considered fruitful for developing such...

In 2007 is het TNO-Meerjarenonderzoeksprogramma Maatschappelijke Veiligheid 2007-2010 van start gegaan. Daarbij gaat het tegelijkertijd om het realiseren van impact op de toekomstige veiligheidssituatie in Nederland en het versterken van de basiskennispositie bij TNO. Dit rapport biedt voor het TNO-management en het regievoerend departement...

In this paper we present a fully automatic system for building 3D models of urban areas at the street level. We propose a novel approach for the accurate estimation of the scale consistent camera pose given two previous images. We employ a new method for global optimization and use a novel sampling technique for primitive fitting to obtain an...

The nerve agent VX is most likely to enter the body via liquid contamination of the skin. After percutaneous exposure, the slow uptake into the blood, and its slow elimination result in toxic levels in plasma for a period of several hours. Consequently, this has implications for the development of toxic signs and for treatment onset. In the...

Understanding acoustic scattering from objects placed on the interface between two media requires incorporation of scattering off the interface. Here, this class of problems is studied in the particular context of a 61 cm long, 30.5 cm diameter solid aluminum cylinder placed on a flattened sand interface. Experimental results are presented for...

Generally, motion simulators present motion and visual cues different from each other due to the physical limitations of the motion platform. Nonetheless, high fidelity motion platforms are capable of simulating some maneuvers one-to-one, i.e., motion cues equal to visual cues. However, one-to-one simulation is normally not preferred by subjects...

High-speed photography has been used to investigate the dynamic behaviour of similar grades of WC-Co hardmetals during ballistic impacts with velocities in the range of 28-484. m/s. Key features of the failure of similar grades of WC-Co materials during complimentary impacts have been observed and discussed. In particular, fast moving fragments...

We explore possibilities for enhancing the generality, portability and robustness of emotion recognition systems by combining data-bases and by fusion of classifiers. In a first experiment, we investigate the performance of an emotion detection system tested on a certain database given that it is trained on speech from either the same database,...

A set of eight sonar problems, pertaining to man-made active sonar, with source frequencies ranging from 250 Hz to 3.5 kHz, is defined. The scenarios are designed to emphasize range dependent propagation aspects in coastal waters, with the aim of testing all terms of the sonar equation (except the detection threshold) both before and after...

Two detectors for space-time adaptive processing (STAP) are proposed here. These are variants that use envelope-law and geometric-mean (GM) (or logarithmic) processing, both being well-known concepts from conventional constant false alarm rate (CFAR) square-law radar detection [212]. The variants are based on normalized adaptive matched filter ...

Previous studies showed that orange odor reduces the anticipatory anxiety and improves the mood of patients waiting for scheduled appointments in small dental practices. We replicated these previous studies in the setting of three large dental clinics. In addition, we investigated whether another pleasant fruity smell (apple odor) is similarly...

A planarly fed UWB leaky lens antenna is presented integrated with wide band transmit and receive front-end electronics, to be used in a SAR-based imaging system. The unique non-dispersive characteristics of this antenna over a very wide bandwidth, together with the dual band front-end electronics based on 'off the shelf' components and...

In this paper we present some preliminary results on the application of Compressive Sensing (CS) to high resolution radar imaging. CS is a recently developed theory which allows reconstruction of sparse signals with a number of measurements much lower than what is required by the Shannon sampling theorem. This method has already found its way in...

Several researchers have argued that the confirmation bias, the tendency to selectively gather and process information such that it fits existing beliefs, is a main threat to objective forensic examinations. The goal of the present study was to empirically investigate whether examiners making bullet comparisons are indeed vulnerable to this bias...

Rigorous equivalent networks representing connected arrays in transmission and reception are derived in this paper. These equivalent networks are not based on reciprocity but on Green's functions. Thus, all components have well identified and physically meaningful roles. A dual-band connected array demonstrator is then presented to validate the...

In this paper, two approaches for compensation of mutual coupling and phase shifts in a passive radar system based on a circular array are compared. The first method is based on the measurement of the antenna scattering parameters and of further relative phase and amplitude variations between the channels introduced by the receiver analog front...

The harmonic retrieval (HR) problem concerns the estimation of the frequencies in a sum of real or complex harmonics. Both correlation and cumulant-based approaches are used for this purpose. Cumulant-based HR algorithms use a single 1-D slice of the fourth-order cumulant that is estimated directly from the data. We present a new cumulant-based...
