We prove a version of the quantum de Finetti theorem: permutation-invariant quantum states are well approximated as a probabilistic mixture of multifold product states. The approximation is measured by distinguishability under measurements that are implementable by fully-one-way local operations and classical communication (LOCC). Our result strengthens Brandão and Harrow's de Finetti theorem w...

strategies of strengthening family foundation mohaddesi h , yusofi m* received: 22 april, 2010 accepted: 27 july, 2010 abstract background & aims: family is the first basis for psychosomatic growth and socialization of individuals in a community. family members who are uninformed or reckless about their rights and responsibilities will make a field for different psychosocial damages such as vio...

background: the purpose of this study was to investigate the effects of two types of rehabilitation techniques, including aerobic and strengthening exercises on patients with knee rheumatoid arthritis (ra). methods: 48 male patients with knee ra were randomly assigned into 3 groups, including aerobic exercises, strengthening exercise, and control. the two first groups completed their treatment ...

Despite their notorious vulnerability, traditional passwords remain important for security. In this paper we describe a method for strengthening passwords. Our method does not require users to memorize or to write down long passwords, and does not rely on smart-cards or other auxiliary hardware. The main cost of our method is that it lengthens the process of checking a password.

results the means ± standard deviations of the averaged emg during the lateral and frontal wp exercises were 40.1 ± 19.1, and 23.7 ± 11.3 µv, respectively. those of the percent maximal voluntary contraction during the lateral and frontal wp exercises were 51.4 ± 29.7, and 31.3 ± 20.5, respectively. gmax activity during the lateral wp exercise was significantly higher than that during the fronta...

A detailed quantitative model for the strengthening of monolithic alloys and composites due to precipitation strengthening, solution strengthening, grain and subgrain strengthening, strengthening by dislocations and load transfer to ceramic inclusions is presented. The model includes a newly derived description of the effect of a precipitate free zone (PFZ) around the reinforcing phase incorpor...

We prove the correctness of incremental lambda-lifting, an optimization that attempts to reduce the closure allocation overhead of higher-order programs by changing the scope of nested procedures. This optimization is invalid in the standard denotational semantics of Scheme, because it changes the storage behavior of the program. Our method consists of giving Scheme a denotational semantics in ...

This study compares the changes in pathway and center of gravity (COG) on the calcaneus of non-involved and involved sides according to eccentric and concentric strengthening in patients with unilateral Achilles tendinopathy. The goal was to define the biomechanical changes according to eccentric strengthening for the development of clinical guidelines. Eighteen patients with Achilles tendinopa...
