A snake (of length L) is a (continuous) piecewise C1-curve S : [0, L] → R, parameterized by arc-length and whose “tail” is at the origin (S(0) = 0). Charming a snake consists in having it move in such a way that its “snout” S(L) follows a chosen C1-curve γ(t). The snake charmer algorithm, initiated in [Ha2] for polygonal snakes and developed in [Ro] in the general case, works as follows. The in...

background: an analysis performed on the collected data from the local drug and poison information centre (dpic) of jundishapur university revealed that stings are the main causes of poisonings with frequency of 56%, followed by drug poisoning in 31%, and chemical exposure poisoning in 5.5% in khuzestan, the southwestern province of iran. objectives: the aim of the present study was to report t...

The present study investigated the ability of a number of presynaptic snake neurotoxins (snake beta-neurotoxins) to produce nerve-evoked train-of-four fade, tetanic fade and endplate potential run-down during the development of neuromuscular blockade in the isolated mouse phrenic-hemidiaphragm nerve-muscle preparation. All the snake beta-neurotoxins tested, with the exception of notexin, produc...

The snake-in-the-box problem is a difficult problem in mathematics and computer science that was first described by Kautz in the late 1950’s (Kautz 1958). Snake-in-the-box codes have many applications in electrical engineering, coding theory, and computer network topologies. Generally, the longer the snake for a given dimension, the more useful it is in these applications (Klee 1970). By applyi...

This paper describes a fast process of parametric snake evolution with a multiresolution strategy. Conventional parametric evolution method relies on matrix inversion throughout the iteration intermittently, in contrast the proposed method relaxes the matrix inversion which is costly and time consuming in cases where the resulting snake is exible. The proposed method also eliminates the input o...

This paper considers the problem of generating various calligraphy from some sample fonts. Our method is based on the deformable contour model g-snake. By representing the outline of each stroke of a character with a g-snake, we cast the generation problem into global and local deformation of g-snake under different control parameters, where the local deformation obeys the energy minimization p...

This paper gives a treatment of various aspects related to snake locomotion. A mathematical model and a physical implementation of a modular snake robot are presented. A control strategy is also developed, yielding a general expression for different gait patterns. Two forms of locomotion have been simulated with the mathematical model, and experiments with the physical snake robot have been con...

OBJECTIVES To describe the clinical syndrome associated with definite tiger snake (Notechis spp) envenoming and to examine the ability of tiger snake antivenom (TSAV) to bind free venom in vivo. DESIGN, SETTING AND PARTICIPANTS We conducted a prospective cohort study within the Australian Snakebite Project, reviewing all definite tiger snake envenoming cases between October 2004 and June 2011...

Snake-poison is a subject of perennial interest to all dwellers in India.For, notwithstanding the laborious researches of numerous distinguished observers, the problem of an antidote to snake-venom still remains unsolved, and poisonous snakes continue to wield their, terrible destructive power with fatal freedom. The physiological action of Indian snake-poison has been carefully studied by Fayr...
