In this article, we study the jumping numbers of an ideal in the local ring at rational singularity on a complex algebraic surface. By understanding the contributions of reduced divisors on a fixed resolution, we are able to present an algorithm for finding of the jumping numbers of the ideal. This shows, in particular, how to compute the jumping numbers of a plane curve from the numerical data...

Recently we found that the marked behavioral difference between isolated and grouped rats occurred under foot shock situations by measuring frequency of jumping behavior in rats (Nishikawa and Tanaka, 1978). We also postulated by the results of methamphetamine administration and the behavioral findings that catecholaminergic hyperactivity especially receptor supersensitivity might play a role i...

[1] A dynamically driven mechanism occurring above severe thunderstorms is described, which can explain the jumping cirrus phenomenon. A three-dimensional, nonhydrostatic cloud model is used to perform numerical simulation of a supercell that occurred in Montana in 1981. The jumping cirrus phenomenon is reproduced in the simulated storm. Analysis of the model results shows that the jumping cirr...

BACKGROUND Certain sites have gained notoriety as 'hotspots' for suicide by jumping. Structural interventions (e.g. barriers and safety nets) have been installed at some of these sites. Individual studies examining the effectiveness of these interventions have been underpowered. METHOD We conducted a meta-analysis, pooling data from nine studies. RESULTS Following the interventions, there w...

A Preble's meadow jumping mouse (Zapus hudsonius preblei) parasitized by five grey flesh fly (Wohlfahrtia vigil) larvae was discovered at the United States Air Force Academy in Colorado Springs, Colorado (USA), in June 1998. This is the first documented case of grey flesh fly parasitism of jumping mice (Family Dipodidae). The lesion was approximately 6 mm wide and was partially hidden under a m...

Harmine (HA) induces a jumping behavior in rats when the central dopaminergic function has been activated. Possible involvement of the GABAergic systems and the benzodiazepine receptors (BZA-R) in the jumping behavior induced by HA and apomorphine (APO) was investigated. Pretreatment with GABAergic agonists, muscimol (0.05-0.2 mg/kg) and diazepam (0.2-1.0 mg/kg), and antagonists, picrotoxin (0....

There have been considerable changes in equipment design and movement patterns in the past few years both in alpine skiing and ski-jumping. These developments have been matched by methods of analysing movements in field conditions. They have yielded new insights into the skills of these specific winter sports. Analytical techniques have included electromyography, kinetic and kinematic methods a...

Introduction: Morphine withdrawal syndrome is mediated via several central and peripheral neurological pathways. In the present study we investigated the role of N-methyl-D aspartic acid (NMDA) glutamate receptor on naloxone-induced withdrawal syndrome in morphine-conditioned mice. Materials and Methods: We designed two separate experiments. In experiment one, 30 male NMRI mice were divide...

Abstract Inspired by the jumping action of frogs, the mechanical structure of four-legs jumping robot is given particularly. This robot is used for the rough terrains or wetland environmental exploration. The four identical legs are mainly composed of a six-bar spring/linkage mechanism integrated with two springs. The D-H parameters, the forward kinematics equation and mechanics analysis on one...
