Let L contain only the equality symbol and let L+ be an arbitrary finite symmetric relational language containing L. Suppose probabilities are defined on finite L+ structures with ‘edge probability”’ n−α. By Tα, the almost sure theory of random L+-structures we mean the collection of L+-sentences which have limit probability 1. Tα denotes the theory of the generic structures for Kα, (the collec...

Modern programming languages provide libraries for concurrent data structures. For better performance, these are implemented with fine-grained concurrency. Still, such implementations are linearizable: the programmer can safely assume that they behave atomically. We formalize this insight in Coq as an end-to-end theorem establishing the semantic preservation of a compiler translating abstract, ...

Hybrids as various resources have valuable importance in tree breeding. Today, improvement programs by using poplar and willows and their hybrids play basic role in supplying wood and decreasing pressure on natural forests. This research was carried out in order to study inter-generic hybridization possibility between Salix aegyptica and Populus caspica species from Salicaceae to achieve new hy...

Two-stage approaches are commonly applied to optimise the stacking sequence of large-scale composite structures. The two stages consist a gradient and non-gradient based optimisation addressing mixed nature continuous discrete constraints design variables detailed sizing laminated For two-stage process be successful, all from both should fulfilled eventually. This study employs generic stacks m...

Saurogobio gracilicaudatus, originally described from the middle Yangtze River (Chang-Jiang in Chinese) basin at Yichang and Guanghua (now Laohekou), Hubei Province, South China, is here re-described, with particular concern for oromandibular structures in the mouth. It is uniquely distinguishable from all other species of Saurogobio in having a rostral cap with a slightly crenulated median por...

Human subjects perceive two crossing bars, one in front of the other, when shown a cross with disparity added to its horizontal limbs, and they also perceive neon-color spreading when shown a stereoscopic Redies-Spillmann figure. It has thus been hypothesized that the human visual system follows the principle of generic image sampling in reconstructing 3-dimensional (3-D) surface structures. He...

This paper aims to examine the generic structures and linguistic properties of ads in Philippine magazines. Taken from the Corpus of Asian Magazine Advertising: The Philippine Database, the corpus consists of seventy-four ads for consumer nondurables such as medicines, vitamins and food supplements, and cosmetic/beauty/personal hygiene products. The study found that the ads demonstrated prefere...

The class of generic structures among those consisting of the measure algebra of a probability space equipped with an automorphism is axiomatizable by positive sentences interpreted using an approximate semantics. The separable generic structures of this kind are exactly the ones isomorphic to the measure algebra of a standard Lebesgue space equipped with an aperiodic measure-preserving automor...
