A micropipette technique was adopted to address the viscoelasticity and its relevance to microtubules and intermediate filaments in rat hepatocytes by treatment with colchicine (Col), acrylamide (Acry) or combination of both. The results showed that: under the concentrations studied, treatment with Acry, Col or combination of both agents resulted in a significant decrease in cell viscoelasticity....
Peer-to-Peer (P2P) mode dominates the way that files are shared over the Internet today. A measurement study on the user behavior during the P2P file sharing is important and helpful to better understand and design P2P networks. In this paper, we developed a method to collect information about peers and connections in movie sharing at the BitTorrent client side. Based on the collected data, we have...
Along with speedy development of society and economy, as well as increasingly fury market competition, an enterprise is hard to accommodate with market requirement on its own since unique personality. Virtual enterprise has been a new organization form in knowledge economic times. This paper analyzed the virtual corporations and the core competence, and put forward corresponding countermeasures against...
Enforcing the tax policies supported by the scientific and technological independent innovation is to promote our scientific and technological level and economic power, which can regulate our economic structure and change the way of our economic growth. This paper gives an analysis on how to make the effective use of tax incentives well and points out that China should actively create a tax policy...
A rotating fan could produce noise of both broadband and discrete frequency. The discrete part typically consists of shaft frequency, blade passage frequency (BPF) and their higher harmonics. The shaft-order noise, which is mainly induced by unbalanced rotating, is often hard to be eliminated. In this paper, the rotating noise caused by geometric asymmetry is discussed and predicted. Analytic point...
It is a problem in application-oriented personnel education that students are hard to apply their knowledge learning from classes. Problem-based learning (PBL) is now a widespread method which can help students learn to apply knowledge. But the teaching condition with limited resources is a big obstruction when using PBL in the undergraduate curriculum. Taking into account this problem, a problem-based...
This paper extends the approximate proximal-extra gradient type algorithm (for short, APEA) presented by He, Yang and Yuan to solve the system of monotone variational inequalities (for short, SMVI). We give the inexact proximal point algorithm for SMVI and prove the convergence of the algorithm under certain assumptions.
According to the uncertainty of indexes in the bid evaluation of power equipment, the entropy value theory is applied to combine the traditional fuzzy comprehensive evaluation method for bid evaluation of power equipment. The coefficients of weight for evaluation factors are obtained from the avail value of data reflecting the information entropy. This method is applied for bid evaluation of power...
By properly adjusting the time delays, phased arrays can dynamically phase-steer and focus the ultrasonic beams. But phase aberration due to perturbation of system and materials degrade ultrasound performance by disrupting the ultrasound beam focus. Such phase aberration exists both in phased array transmission and reception focusing procedure. Currently, phase correction methods are implemented by...
