We present an application-specific integrated circuit (ASIC) CMOS chip that implements a synchronized oscillator cellular neural network with a matrix size of 32 × 32 for object sensing and labeling in binary images. Networks of synchronized oscillators are a recently developed tool for image segmentation and analysis. Its parallel network operation is(More)
Recombinant vesicular stomatitis virus (rVSV) vectors offer an attractive approach for the induction of robust cellular and humoral immune responses directed against human pathogen target antigens. We evaluated rVSV vectors expressing full-length glycoprotein D (gD) from herpes simplex virus type 2 (HSV-2) in mice and guinea pigs for immunogenicity and(More)
In this paper, a very large scale integration chip of an analog image weighted-order statistic (WOS) filter based on cellular neural network (CNN) architecture for real-time applications is described. The chip has been implemented in CMOS AMS 0.8 /spl mu/m technology. CNN-based filter consists of feedforward nonlinear template B operating within the window(More)

The paper presents the features and samples of use of the optimization by indices module implemented in the ODRA (Object Database for Rapid Applications development) prototype system. The ODRA indices implementation is based on Linear Hashing that can be used for standalone databases as well as for distributed environments in order to optimally utilize data(More)
THE AIM OF THE STUDY The aim of the study was to evaluate the spectrum of AIDS-defining malignancies (ADMs) and non-AIDS-defining malignancies (NADMs) in HIV-infected patients in Poland. MATERIAL AND METHODS A retrospective observational study was conducted among HIV-infected adult patients who developed a malignancy between 1995 and 2012 in a Polish(More)
The physiological characteristics and organization of cat primary somatosensory cortex (SI) were studied in electrophysiological and anatomical experiments. In single cell recording experiments, quantitatively controlled mechanical stimuli were used to examine the responses of SI cortical neurons to the velocity component of skin or hair displacement. The(More)
This paper presents functional tests results of CMOS VLSI ASIC integrated circuit, which implements a network of synchronised oscillators. The network chip architecture was briefly described. This circuit was designed for segmentation of binary images, which is an important issue in biomedical image analysis. The hardware realisation of oscillator network(More)

A herpes simplex virus type 2 (HSV-2) UL24 ␤-glucuronidase (UL24-␤gluc) insertion mutant was derived from HSV-2 strain 186 via standard marker transfer techniques. Cell monolayers infected with UL24-␤gluc yielded cytopathic effect with syncytium formation. UL24-␤gluc replicated to wild-type viral titers in three different cell lines. UL24-␤gluc was not(More)
