Geographic variation may ultimately lead to the splitting of a subdivided population into reproductively isolated units in spite of migration. Here, we consider how the waiting time until the first split and its location depend on different evolutionary factors including mutation, migration, random genetic drift, genetic architecture, and the geometric structure of the habitat. We perform large...

In addition to patch-level attributes (i.e., area and isolation), the nature of land cover between habitat patches (the matrix) may drive colonization and extinction dynamics in fragmented landscapes. Despite a long-standing recognition of matrix effects in fragmented systems, an understanding of the relative impacts of different types of land cover on patterns and dynamics of species occurrenc...

Aiming to effectively recognize train center plate bolt loss faults, this paper presents an improved fault detection method. A multi-scale local binary pattern operator containing the local texture information of different radii is designed to extract more efficient discrimination information. An improved teaching-learning-based optimization algorithm is established to optimize the classificati...

Background: Motile sperm is essential for successful embryo production. The aim of the present study was to compare the in vitro embryo development following isolation of Ram epididymal sperm isolation by swim up (SP) or Histoprep® continuous gradient (HP). Materials and Methods: Ram testes-epididymis were provided from the local slaughterhouse and transported to the lab. Sperms were recovered ...

Within-species colour variation is widespread among animals. Understanding how this arises can elucidate evolutionary mechanisms, such as those underlying reproductive isolation and speciation. Here, we investigated whether five island populations of Aegean wall lizards (Podarcis erhardii) have more effective camouflage against their own (local) island substrates than against other (non-local) ...

This paper investigates the vibration isolation performance of isolated box structures. Isolated box inside building is a one of the building isolation designs. Some experimental methods are developed to analyze the effects of bending mode of the box structure on vibration isolation efficiency. The vibration reduction performance of an isolated box inside building is found to be degraded by ben...

The need for technology has always found space in Financial Transaction as the number of fraud financial transactions increases day by day. In this research we have proposed a new methodology using isolation forest algorithm and local outlier detection to detect fraud. A standard data set is used experimentation classify transaction occurred fraudulent or not. We neural networks machine learnin...
