Let Z → X be a nite branched Galois cover of normal projective geometrically integral varieties of dimension d ≥ 2 over a perfect eld k. For such a cover, we prove a Chebotarev-type density result describing the decomposition behaviour of geometrically integral Cartier divisors. As an application, we classify Galois covers among all nite branched covers of a given normal geometrically integral ...

The Shaker locus of Drosophila melanogaster encodes a family of A-type potassium channel subunits. Shaker mutants behave as antimorphs in gene dosage tests. This behaviour is due to the production of truncated A-channel subunits. We propose that they interfere with the function of their normal counterpart by forming multimeric A-channel structures. This hypothesis was tested by constructing tra...

This paper presents an approach to preventing the damage caused by viruses that travel via email. The approach prevents an infected machine spreading the virus further. This directly addresses the two ways that viruses cause damage: less machines spreading the virus will reduce the number of machines infected and reduce the traffic generated by the virus. The approach relies on the observation ...

Intrusion detection systems (IDS) aim to protect computer systems against attacks. The detection methods employed in anomalybased IDS are based, in particular, on monitoring networks for patterns of activity that differ from normal behaviour. Issues to be addressed with anomaly-based systems include deciding and representing what constitutes normal behaviour as well as being able to detect devi...

in this study, we focused on the gait of parkinson’s disease (pd) and presented a gray box model for it. we tried to present a model for basal ganglia structure in order to generate stride time interval signal in model output for healthy and pd states. because of feedback role of dopamine neurotransmitter in basal ganglia, this part is modelled by “elman network”, which is a neural network stru...

behaviour studies indicated that the permethrin resistant strin of an. stephensi was 3-fold resistant to knock-down compared with the susceptible strain. the resistant strain was however 3-fold less irritable to permethrin and less responsive than the susceptible strain to the movement of an aspirator. if reduced irritability and reduced responsiveness to catch are consequences of the changes i...

a cross-sectional study with children's and parents' self-completed questionnaires was carried out to evaluate parents' ideas on children's risk-takjng behaviours and children's risky activities after school hours by age (7 and 9 years) and sex. nine elementary schools were randomly selected and 476 puphs aged seven and nine years and 471 parents were studied. most pare...

Stereotypy is the narrowing down of an animal’s behavioural repertoire. Starting from normal behaviour there is a continuum between rich and free behaviour on the one hand, and dull and Ž predictable stereotypies on the other. To study the continuum all that one needs are ‘‘knobs’’ like . drugs or stress that shift the behaviour from one end to the other, and a method for documenting the behavi...

in this paper a first step in classifying the fuzzy normalsubgroups of a finite group is made. explicit formulas for thenumber of distinct fuzzy normal subgroups are obtained in theparticular cases of symmetric groups and dihedral groups.
