BACKGROUND Analysis of genetic polymorphisms in short tandem repeats (STRs) is an accepted method for detecting associations between genotype and phenotype but it has not previously been used in the study of the genetics of impulsive violent behavior. OBJECTIVE Compare the prevalence of different polymorphisms in 15 STR loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D...

The results of a measurement campaign conducted to determine the wideband behaviour of the radio channel assigned to Multimedia Wireless Systems are described in this paper. It has been found that small multipath components are present in the impulsive response of radio channels operating at 40 GHz with 80 MHz bandwidths. Multipath and delay spread are limited by the spatial filtering of direct...

We present a Field Programmable Logic Devices (FPLDs) based implementation of a scalable filter architecture capable of detecting and removing impulsive noise in image sequences. The adaptive filter architecture is built using switching spatiotemporal filtering scheme and robust Lower-Upper-Middle (LUM) based noise detector. It uses highly optimized bit-serial pipelined implementation in Altera...

The use of frequency-shift (FRESH) filtering for the rejection of adjacent channel interference (ACI) in GMSK modulated VLF communications is investigated in the presence of impulsive noise. The effects of such filtering in conjunction with a simple “hole-punching” technique for removing impulses from the signal are characterised. A range of realistic scenarios based on a high powered GMSK inte...

Experimentally determined natural frequencies and modes shapes are presented for an elastically point-supported isotropic plate with attached masses under impulsive loading. These results are compared to frequencies and to modes shapes determined from the Rayleigh–Ritz method and a finite element analysis using COMSOL. Accelerometers mounted at three locations on the plate, provide input for ME...

Host-parasitoid models including integrated pest management (IPM) interventions with impulsive effects at both fixed and unfixed times were analyzed with regard to host-eradication, host-parasitoid persistence and host-outbreak solutions. The host-eradication periodic solution with fixed moments is globally stable if the host's intrinsic growth rate is less than the summation of the mean host-k...

In this paper, we propose a robust direction-of-arrival (DOA) estimation algorithm based on group sparse reconstruction algorithm utilizing signals observed at multiple frequencies. The group sparse reconstruction scheme for DOA estimation is solved through the complex multitask Bayesian compressive sensing algorithm by exploiting the group sparse property of the received multi-frequency signal...

Abstract With the increasingly deepen knowledge on structural dynamic behaviour, nowadays, monumental staircases and their steps are usually designed with high stiffness low mass, obtaining fundamental frequencies, out of interval step frequencies excitable by human walking. However, neglecting structure’s mass can also result in levels impulsive responses. Furthermore, often connection between...

Aim To investigate impulsive behaviors in pathological buying (PB). Methods The study included three groups matched for age and gender: treatment seeking outpatients with PB (PB+), treatment seeking psychiatric inpatients without PB (PB-), and a healthy control group (HC). PB was assessed by means of the Compulsive Buying Scale and by the impulse control disorder (ICD) module of the research ve...
