Lattice paths: vicious walkers and friendly walkers
In an earlier paper [4] the problem of vicious random walkers on a d-dimensional directed lattice was considered. \Vicious walkers" describes the situation in which two or more walkers arriving at the same lattice site annihilate one another. Accordingly, the only allowed con gurations are those in which contacts are forbidden. Alternatively expressed as a static rather than dynamic problem, vi...
متن کاملCrutch induced axillary artery injury.
CASEREPORT A 53-year-old female presented with sudden onset of pallor and decreased sensation of the right hand and forearm, without loss of power. She had rheumatoid arthritis for the last 30 years, and had been using axillary crutches for the last 10 years. She had undergone bilateral knee and left hip replacements. There were no other significant cardiovascular risk factors, nor any previous...
متن کاملMultivalent Random Walkers - A Model for Deoxyribozyme Walkers
We propose a stochastic model for molecular transport at the nanoscale that describes the motion of two-dimensional molecular assemblies called multivalent random walkers (MVRWs). This walker model is an abstract description of the motion of multipedal molecular assemblies, called molecular spiders, which use deoxyribozyme legs to move over a surface covered with substrate DNA molecules, cleavi...
متن کاملThe design of a compliant composite crutch.
Ambulation by crutches takes up to twice the energy of normal gait and can lead to injuries of the hands and arms. The compliant composite forearm crutch described in this article seeks to address these problems. The new crutch is made of a single composite piece and has an S-curve in the main body to provide shock absorption and return of energy with the goal of reducing impact and repetitive ...
متن کاملFamilies of Vicious Walkers
We consider a generalisation of the vicious walker problem in which N random walkers in R are grouped into p families. Using field-theoretic renormalisation group methods we calculate the asymptotic behaviour of the probability that no pairs of walkers from different families have met up to time t. For d > 2, this is constant, but for d < 2 it decays as a power t, which we compute to O(ε) in an...
