Why some dyadic interactions are more likely than others to trigger hinder the generation of novel and useful ideas? To investigate this question, we examine the attributes of dyadic ties that influence the generation of creative ideas, and how the strength of influence changes contingently on the mix use of communication media. Our study extends previous research by examining the impacts of Si...

In this paper, new developments concerning a system for informed source separation (ISS) of music signals are presented. Such system enables to separate I > 2 musical instruments and singing voices from linear instantaneous stationary stereo (2-channel) mixtures, based on audio signal natural sparsity, pre-mix source signal analysis, and side-information embedding (within the mix signal). The f...

One of the most difficult problems in health care policy is adjusting payment to activity. Particularly little is known about how resources are allocated to departments of geriatric care. To investigate whether departments of geriatric medicine in Stockholm, Sweden relate their costs to case-mix, one of the most well-known case-mix systems for geriatric care, the Resource Utilization Groups, ve...

Vehicular Networks (VNs) seek to provide, among other applications, safer driving conditions. To do so, vehicles need to periodically broadcast safety messages providing precise position information to nearby vehicles. However, this frequent messaging (e.g., every 100 to 300ms per car) greatly facilitates the tracking of vehicles, as it suffices to eavesdrop the wireless medium. As a result, th...

Protect the identity of participants may be advantageous or essential and even critical for many internet applications. Mix rings architecture give better performance than mix-nets while maintaining anonymity that is stronger than onion routing. This paper presents an enhancement of mix rings, which is a hybrid P2P system and is designed to provide anonymity under a strong adversarial model in ...

BACKGROUND AND PURPOSE The objective of this study was to estimate the level of health outcomes and resource use at a hospital level during the first year after a stroke, and to identify any potential differences between hospitals after adjusting for patient characteristics (case mix). METHOD Data from several registries were linked on individual level: seven regional patient administrative s...

Digital technologies are profoundly transforming the production and consumption of culture and entertainment products. The emerging digital re-mix culture is an open source approach where content products in the arts and entertainment industries are increasingly rearranged, manipulated , and extended in the process of creating new works. This article offers a unified description of the tools an...

Firms use a rich set of incentives including fixed wages, bonuses, threat of firing and promise of promotion. Yet, we do not have a theoretical understanding of how such a mix of incentives can arise. This paper aims to build a theoretical model which describes the incentive mix as the solution to an optimal contracting problem and provides broader testable implications. The basic model has a p...

Humalog Mix 75/25 insulin analog is widely used in the People's Republic of China to treat type 2 diabetes mellitus, but the Humalog Mix 50/50 analog is not as yet widely used or assessed. The purpose of this 12-week, parallel-group, randomized, treat-to-target study was to evaluate the difference in clinical efficacy, safety, and outcome of treatment between Humalog Mix 50/50 and Humalog Mix 7...
