Grazing behavior exhibited by different biological types (breed groups) of lactating beef cows was evaluated during the summers of 1985 (Trial 1) and 1986 (Trial 2). Animals grazed native Montana foothill grassland. In Trial 1, breed groups consisted of Hereford (HH), 50% Angus-50% Hereford (AH), 50% Simmental-50% Hereford (SH), and 75% Simmental-25% Hereford (3S1H) with six cows per breed grou...

Modeling natural systems is a complicated task that involves the concurrent behavior of various processes, mechanisms and objects. Here, we describe an approach that we have been taking in our group for several years, whereby the complexity of the problem is reduced by decomposing a natural system into its basic elements, which are then reassembled and combined to form a comprehensive, simulata...

Biological networks play a key role in determining biological function and therefore, an understanding of their structure and dynamics is of central interest in systems biology. In Boolean models of such networks, the status of each molecule is either "on" or "off" and along with the molecules interact with each other, their individual status changes from "on" to "off" or vice-versa and the sys...

Phyllodes tumor is an uncommon fibro epithelial breast tumor with diverse biological behavior. The tumor closely resemble as fibroadenoma of the breast. On one end phyllodes is slow growing benign tumor, the other end tumor grows rapidly behave like sarcoma which metastasizes, and phyllodes can turn to frank sarcoma. Tumor can be diagnosed on clinical basis i.e. large mass with lobulated (bosse...

Typical load-bearing biological materials like bone, mineralized tendon and shell, are biocomposites made from both organic (collagen) and inorganic (biomineral) materials. This amazing class of materials with intrinsic internally designed hierarchical structures show superior mechanical properties with regard to their weak components from which they are formed. Extensive investigations concent...

Human environments consist to a large extent of repeated spatiotemporal patterns which are typically composed of simpler patterns. Most humans are thus surrounded by houses, streets, cars, shops, and omnipresent behavior patterns composed of verbal and nonverbal elements. Human individuals are, of course, themselves patterns of parts, such as trunk, head, arms, and legs, that again are composed...

Although studies examining the biological roots of human behavior have been conducted since the seminal work Kahneman and Tversky, crises and panics have not disappeared. The frequent occurrence of various types of crises has led some economists to the conviction that financial markets occasionally praise irrational judgments and that market crashes cannot be avoided a priori (Sornette 2009; Sm...

We present the case of a 13-month-old girl with a right occipital cortical alteration on MRI that proved to be a growing lesion. Tumor growth had been observed over a period of 15 months before total resection was performed, revealing a dysembryoplastic neuroepithelial tumor WHO grade I. This case shows that dysembryoplastic neuroepithelial tumors can present as growing neoplasias. It underline...

The prevailing cognitive-psychological accounts of event-related brain potentials (ERPs) assume that ERP components manifest information processing operations leading from stimulus to response. Since this view encounters numerous difficulties already analyzed in previous studies, an alternative view is presented here that regards cortical control of behavior as a repetitive sensorimotor cycle c...
