PELOUZE and Bernard (1850) first described the peripheral nature of curare paralysis. Further investigation, begun in 1852 by Claude Bernard, demonstrated the action of curarine to be at the neuromuscular junction (Bernard, 1856). Thus, one hundred years ago, the idea crystallized that the central actions of curare were unimportant or nonexistent, and was given form by such statements as " Mais...
The Euler graph has vertices labelled (n, k) for n = 0, 1, 2, ... and k = 0, 1, ..., n, with k + 1 edges from (n, k) to (n + 1, k) and n − k + 1 edges from (n, k) to (n + 1, k + 1). The number of paths from (0,0) to (n, k) is the Eulerian number A(n, k), the number of permutations of 1,2,...,n+ 1 with exactly n− k falls and k rises. We prove that the adic (Bratteli-Vershik) transformation on th...
About 50% of the world’s population is infected with Helicobacter pylori (H. pylori), which is a causative agent for gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue (MALT) lymphoma, and gastric cancer (Salama et al., 2013). It is estimated that individuals infected with H. pylori have more than two-fold increased risk of developing gastric cancer compared with noninfected one...
For multi-objective optimization in the QoS routing, this paper combines the artificial fish swarm algorithm and ant colony algorithm and tabu search algorithm, proposes a new improved algorithm, and delves into the application of solving the QoS routing. One main work in this paper is to put forward a mixed algorithm integrating artificial fish swarm and ant colony. Firstly, we randomly genera...

The head of the World Health Organization’s (WHO) Health Emergencies Programme expressed alarm at reports of the use of highly toxic chemicals in an attack in the Syrian Arab Republic on 5 April. At least 70 people died and hundreds more were affected in Khan Shaykhun in the governorate of Idleb, according to United Nations Health Cluster partners who were treating patients – many of them women...
An alkaliphilic-thermotolerant Bacillus cereus N1 isolated from Bani Salama Lake, Wadi El-Natron, Egypt, was proved to produce mannanase enzyme. Optimization of the fermentation medium components using Plackett-Burman design was applied. Glucose and inoculum size were found to be the most significant factors enhancing the production of the enzyme. On applying optimized medium in the fermentatio...
In this paper we present a new algorithm for interactively painting onto 3D meshes that exploits recent advances of GPU technology. As the user moves a brush over the 3D mesh, its paint pattern is projected onto the 3D geometry at the current viewing angle and copied to the corresponding region in the object’s texture atlas. Both operations are realized on the GPU, with the advantage that all d...
Although Gödel proved the first incompleteness theorem by intuitionistically respectable means, Gödel’s formula, true although undecidable, seems to offer a counter-example to the general constructivist or anti-realist claim that truth may not transcend recognizability in principle. It is argued here that our understanding of the formula consists in a knowledge of its truth-conditions, that it ...
A universal schema for diagonalization was popularized by N.S. Yanofsky (2003), based on a pioneering work of F.W. Lawvere (1969), in which the existence of a (diagonolized-out and contradictory) object implies the existence of a fixed-point for a certain function. It was shown that many self-referential paradoxes and diagonally proved theorems can fit in that schema. Here, we fi...
