We consider two non-interacting systems embedded in a heat bath. If they remain dynamically independent, physical inconsistencies are avoided only if the single-system reduced dynamics is completely positive also beyond the weak-coupling limit.

Rolling element bearing failure is one of the foremost causes of breakdown in rotating machinery. It is not uncommon to replace a defected/used bearing with a new one that has shorter remaining useful life than the defected one. Thus, prognostics of bearing plays critical role for increased availability and reduced cost. Effective prognostics highly depend on the quality of the extracted featur...

Human body requires certain essential elements in small quantities and their absence or excess may result in severe malfunctioning of the body and even death in extreme cases because these essential trace elements directly influence the metabolic and physiologic processes of the organism. Rapid urbanization and economic development have resulted in drastic changes in diets with developing prefe...

A trace of a workload’s system calls can be obtained with minimal interference, and can be used to drive repeatable experiments to evaluate system configuration alternatives. Replaying system call traces alone sometimes leads to inaccurate predictions because paging, and access to memorymapped files, are not modelled. This paper extends tracing to handle such workloads. At trace capture time, t...

An investigation was carried out to determine whether a Day 28 to 49 dietary vitamin, trace mineral, and vitamin plus trace mineral premix withdrawal would impact Pectoralis major thiamin or riboflavin concentration in chicks reared under thermoneutral (24 C) and heat-stressed (24 to 35 C) conditions. No significant (P > 0.1) environment by nutrient withdrawal interactions were detected. Heat s...

background: within the context of developing techniques to facilitate the diagnosis of the thyroid diseases, the elemental composition of pathological thyroid tissue (neoplastic and non-neoplastic) was investigated by proton induced x-ray emission. the pixe has been widely used as a sensitive technique for trace elemental analysis in both biological and medical fields. materials and methods: th...

wound healing in the skin depends upon the availability of appropriate trace metals as enzyme cofactors and structural components in tissue repair. the present study is a part of a series of experimental investigations to examine the influence of bentonite on skin wound healing. surgically induced skin wounds in 48 young adult male rats were exposed topically to bentonite (12 round wound and 12...

Background: Alopecia areata (AA) is a common localized nonscarring hair loss. Vitamin D and such trace elements as zinc have significant immunomodulatory roles and are reduced in many autoimmune diseases. We aim to evaluate the zinc and vitamin D levels in AA patients belonging to an Iranian population. Methods: We randomly recruited 77 patients with AA, and 112 age- and sex-matched normal subj...

We have isolated beta-trace protein from cerebrospinal fluid, serum, plasma, and urine samples of normal volunteers and sera and hemofiltrate of patients with chronic renal failure. Blood-derived and urinary beta-trace have significantly higher molecular weights than their cerebrospinal fluid counterpart, the amino acid sequences being identical. Oligosaccharide structural analysis revealed the...
