in this paper, a new analytical method is proposed to study the effect of crack and axial load on vibration behavior and stability of the cracked columns. using the local flexibility model, the crack has been simulated by a torsional spring with connecting two segments of column in crack location. by solving governing eigenvalue equation, the effect of crack parameters and axial load on the nat...

In this commentary, we discuss Gersten’s findings particularly in relation to the challenge of accurately measuring stress, neuroendocrine markers and allostatic load. Allostatic load is a timely, potentially useful tool to measure the degree in which the body’s physiological function is outside of optimal range. As with most biomarkers early on in development, there are sound opportunities to ...

A parallel server system is considered, with I customer classes and many servers, operating at a heavy traffic diffusion regime where the queueing delay and service time are of the same order of magnitude. Denoting by X̂ and Q̂ the diffusion scale deviation of the headcount process from the quantity corresponding to the underlying fluid model and, respectively, the diffusion scale queue-length, w...

For a large class of examples arising in statistical physics known as attractive spin systems (e.g., the Ising model), one seeks to sample from a probability distribution π on an enormously large state space, but elementary sampling is ruled out by the infeasibility of calculating an appropriate normalizing constant. The same difficulty arises in computer science problems where one seeks to sam...

Many cloud service providers (CSPs) offer an on-demand with a small delay. Motivated by the reality of ecosystems, we study non-interruptible services and consider differentiated model to complement existing market offering multiple level agreements (SLAs) satisfy users different delay tolerance. The itself is incentive compatible construction. Two typical architectures are considered fulfill S...

background: hepatitis activity index (hai) and fibrosing stage are two important findings during the evaluation of liver samples in patients with chronic hepatitis b. the aim of this study was to determine the hai and fibrosing stage in patients with anti-hbe positive chronic hepatitis b. methods: liver biopsy slides of 72 patients were evaluated at the department of pathology in two teaching h...

background: the study evaluated qualitative pcr, primers 121-122 as a tool to follow up evolution parasite load of trypanosoma cruzi . methods: the study was conducted at the state university of maringa, in 2015. step 1, dilutions 1/10 were performed from t. cruzi -y strain to obtain preparations of 50,000-0.05 parasites/ml from which dna were extracted, quantified, and amplified. step 2, the e...
