In a variety of species, females choose mates on the basis of traits such as male body size, ornamentation, courtship vigor or morphological symmetry. In general, the two sexes have very different reproductive strategies, females being more discriminating in their choice of mates than males are. For example, Bateman (1948) observed that male fruit flies try to mate with almost any female, where...

Background subtraction methods are widely used to detect moving objects from static cameras. Many different methods have been proposed, reviewed and categorised based on their complexity, speed, memory requirements and accuracy. The Running Gaussian Average is a simple method offering acceptable accuracy and high frame rate while having low memory requirements. Originally this method was propos...

Two color microarrays are a powerful tool for genomic analysis, but have noise components that make inferences regarding gene expression inefficient and potentially misleading. Background fluorescence, whether attributable to non-specific binding or other sources, is an important component of noise. The decision to subtract fluorescence surrounding spots of hybridization from spot fluorescence ...

Background & Objective:  Vibrio cholerae is a natural inhabitant of the environment and causes severe diarrhea ailments (cholera) that affects thousands of people each year worldwide. The most important virulence factors of this pathogen are cholera toxin (cholera toxin CT) and Type IV...

Background & Objective:  Acute lymphoblastic leukemia (ALL) is a malignant disease that arises from various mutations in B or T-lymphoid progenitors. MicroRNAs (miRNAs) regulate gene expression by binding to the 3' untranslated region of protein-coding genes. Dysregulation of miRNA expression m...

Detecting skin color from image sequences has played an important role in many computer vision applications, such as face detection and tracking. Even though there are a number of approaches for skin color detection, most of the existing algorithms produce false positives when non-skin pixels have similar color to skin color. To overcome this problem, this paper proposes a method that combines ...

In this article, the corresponding-color data for complex images reproduced on different media were obtained by simultaneous matching using an adjustment method. In our experiment printed color images and images displayed on a monitor were compared in different viewing conditions. The viewing condition varied in surround relative luminance and background. The experimental data show that surroun...

175 om m unation It is important to prepare a suitable microsurgical environment for vascular anastomosis or nerve suture. The background sheet is a useful element of this preparation, as it prevents the tissue and nylon thread from sticking and it can pull the sutured nylon thread. Various types of commercially produced background sheets are used according to the surgeon’s preference. In order...
