During embryonic development, restricted expression of the regulatory genes Krox20 and kreisler are involved in segmentation and antero-posterior patterning of the hindbrain neural tube. The analysis of transgenic mice in which specific rhombomeres (r) are eliminated points to an important role of segmentation in the generation of neuronal networks controlling vital rhythmic behaviours such as ...

A new species of indotyphlid caecilian amphibian, Gegeneophis tejaswini sp. nov., is described based on eight specimens from lowlands of the most northerly district of the state of Kerala in the southern part of the Western Ghats region, India. This species is distinguished from all other Gegeneophis in annulation characters and genetics (> 6% different from most similar nominal species for ...

Knowledge representation (KR) is the most desirable area of research to make the system intelligent. Today is the era of knowledge that requires articulations, semantic, syntax etc. These requirements, forced to design a general system which is applicable to represent declarative as well as procedural knowledge. Without effective inference/reasoning mechanism, the strength and utility of knowle...

Molecular dynamics simulations of water with both multi-Kr and single Kr atomic solutes are carried out to implement quasi-chemical theory evaluation of the hydration free energy of Kr(aq). This approach obtains free energy differences reflecting Kr-Kr interactions at higher concentrations. Those differences are negative changes in hydration free energies with increasing concentrations at const...

Given three positive integers r,m and g, one interesting question is the following: What is the minimum number of vertices that a graph with prescribed degree set {r,m}, 2 ≤ r < m, and girth g can have? Such a graph is called a bi-regular cage or an ({r,m}; g)-cage, and its minimum order is denoted by n({r,m}; g). In this paper we provide new upper bounds on n({r,m}; g) for some related values ...

A lacunary sequence is an increasing integer sequence θ = (kr) such that k0 =0, kr−kr−1 →∞ as r →∞. A sequence x is called Sθ(∆)− convergent to L provided that for each ε > 0, limr(kr − kr−1) {the number of kr−1 < k ≤ kr : |∆xk−L| ≥ ε} = 0, where ∆xk = ∆xk− ∆xk+1. The purpose of this paper is to introduce the concept of ∆ − lacunary statistical convergence and ∆-lacunary strongly convergence an...

The single atom counting rate of a rare isotope and the loading rate of another stable isotope with an abundance over 10 orders of magnitude larger are measured in one atom trap. The linear correlation between the measured counting/loading rates is examined to determine the (84)Kr/(82)Kr and (85)Kr/(83)Kr ratios of a Kr gas sample. Experiments show that the relative uncertainty is reduced to 1....

Xe and Kr gases produced during the use of uranium dioxide (UO2)-fuelled reactors can easily form bubbles, resulting in fuel swelling or performance degradation. Therefore, it is important to understand influence point defects on behaviour UO2. In this work, effects behavioural characteristics Xe/Kr clusters UO2 have been systematically studied using molecular dynamics. The results show that oc...

Blocking of poly(ADP-ribose) polymerase (PARP)-1 has been expected to protect the heart from ischemia-reperfusion injury. We have recently identified a novel and orally active PARP-1 inhibitor, KR-33889 [2-[methoxycarbonyl(4-methoxyphenyl)-methylsulfanyl]-1H-benzimidazole-4-carboxylic acid amide], and its major metabolite, KR-34285 [2-[carboxy(4-methoxyphenyl)methylsulfanyl]-1H-benzimidazole-4-...
