Microaggregation is a special clustering problem where the goal is to cluster a set of points into groups of at least k points in such a way that groups are as homogeneous as possible. Microaggregation arises in connection with anonymization of statistical databases for privacy protection (k-anonymity), where points are assimilated to database records. A usual group homogeneity criterion is wit...

Background: The ability of managers of small-scale enterprises (SSEs) to prioritize health, working conditions, and their own physical fitness is an important issue for workplace health promotion in Norway and Sweden, where most owner-manager positions are in SSEs. Aim: To assess the physical fitness status of SSE managers compared to a norm population and to study changes in physical fitness s...

We would like to explain why AES instructions should be considered: Based on our observation that Intel CPU performance figures of several SHA-3 candidates are due to the use of instructions in SSE, we think that new version of SSE which employs AES instructions should be considered as the same way as the current version of it. We expect that Intel CPUs with AES instructions will be widely used...

In a searchable symmetric encryption (SSE) scheme, a client can keyword search over symmetrically-encrypted files which he stored on the server (ideally without leaking any information to the server). In this paper, we show the first multiple keyword search SSE scheme such that even the search formula f (AND, OR and so on) is kept secret. Our scheme is based on an extended garbled circuit satis...

BACKGROUND AND PURPOSE The prevalence of atrial fibrillation increases with age, but age-specific data on the incidence of stroke and death in anticoagulated patients with atrial fibrillation are more limited, particularly with regard to comparisons of relative risks of clinical outcomes between the different age strata in relation to quality of anticoagulation control among warfarin users. M...

Given any sequence z = (zn)n≥1 of positive real numbers and any set E of complex sequences, we write Ez for the set of all sequences y = (yn)n≥1 such that y/z = (yn/zn)n≥1 ∈ E; in particular, cz denotes the set of all sequences y such that y/z converges. By w∞, we denote the set of all sequences y such that supn≥1(n −1 ∑n k=1 |yk|) < ∞. By ∆ we denote the operator of the first difference define...

Oblivious RAM (ORAM) is a tool proposed to hide access pattern leakage, and there has been a lot of progress in the efficiency of ORAM schemes; however, less attention has been paid to study the applicability of ORAM for cloud applications such as symmetric searchable encryption (SSE). Although, searchable encryption is one of the motivations for ORAM research, no in-depth study of the applicab...

The spatial pattern of synapse activation may impact on synaptic plasticity. This applies to the synaptically-evoked endocannabinoid-mediated short-term depression at the parallel fiber (PF) to Purkinje cell synapse, the occurrence of which requires close proximity between the activated synapses. Here, we determine quantitatively this required proximity, helped by the geometrical organization o...

Falls and fall related injuries become an emerging health problem among older adults. As a result a review of the recent evidences is needed to design a prevention strategy. The aim of this review was to determine the effect of square stepping exercise (SSE) for fall down injury among older adults compared with walking training or other exercises. An electronic database search for relevant rand...
