We address the problem of multi-objective constraint optimization problems (MO-COPs). Solving an MO-COP traditionally consists in computing the set of all Pareto solutions (i.e. the Pareto front). But this Pareto front is exponentially large in the general case. So this causes two main problems. First is the time complexity concerns. Second is a lack of decisiveness. In this paper, we present t...

Following a question of Anstee and Farber we investigate the possibility that all bridged graphs are cop-win. We show that in7nite chordal graphs, even of diameter two, need not be cop-win and point to some interesting questions, some of which we answer. c © 2002 Elsevier Science B.V. All rights reserved.

C monoxide poisoning (COP) is a common occurrence in today’s society, one of the most common poisonings worldwide, and is responsible for more fatalities than other toxic agent.1 Carbon monoxide has been termed the “silent killer” due its physical characters as well as its mechanism of action. It is generally accepted that, unintentional COP may be partially preventable through public education...

To determine how arm movements influence postural sway in the upright position after stroke, interactions between arm, trunk, and center of pressure (CoP) displacements in the sagittal direction were investigated in participants with hemiparesis and healthy subjects. Participants swung both arms sagittally in either of 2 directions (in-phase, anti-phase) and at 2 speeds (preferred, fast) while ...

It has previously been shown that the Copenhagen (COP) rat contains several genetic loci that contribute to its mammary tumor-resistant phenotype after 7,12-dimethylbenz(a)anthracene (DMBA) administration. One of these loci, mammary carcinoma susceptibility 1 (Mcs1), is located on the centromeric end of chromosome 2 and appears to act in a semidominant fashion. To confirm the existence and inde...

Leprosy is a granulomatous disease that affects the peripheral nervous system, leading to loss of thermal, tactile and pain sensibility. Changes in plantar sensibility and proprioception caused by leprosy might affect postural balance control. The Body Center of Pressure (COP) constitutes the neuromuscular response to changes or accelerations of the body’s Center of Gravity and can be affected ...

We describe and justify thirteen technical properties that a component system must possess to work with object-oriented programming languages (such as Java, C++, or C#). Our components are designed for large-scale, modular construction of programs with static checking of program compositions. Jiazzi, our enhancement of Java, implements the technical properties that we describe. We use Jiazzi co...

A terrified woman called police because her ex-boyfriend was breaking into her home. Upon arrival, police heard screams coming from the basement. They stopped halfway down the stairs and found the ex-boyfriend pointing a rifle at the floor. Officers observed a strange look on the subject’s face as he slowly raised the rifle in their direction. Both officers fired their weapons, killing the susp...

We consider a search game on a graph in which one cop in a helicopter ying from vertex to vertex tries to catch the invisible robber. The existence of the winning program for the cop in this problem depends only on the robber's speed. We investigate the problem of nding the minimal robber's speed which prevents the cop from winning. For this parameter we give tight bounds in terms of the linkag...
