The Process of developing large software systems creates many source code files with complex inter-dependencies. Clusters of mutually dependent files introduce the possibility of a chain of forced consequential changes when a single cluster member file is changed. The software development risk model, developed here, shows that the density of dependencies within such clusters plays a crucial rol...

OBJECTIVE Chronic pain from rheumatic and musculoskeletal conditions is associated with cortical changes and altered tactile acuity. Tactile acuity is considered a clinical signature of primary somatosensory representation. The two-point discrimination (TPD) threshold is increasingly used both clinically and in research. Remarkably, the reliability and precision of the measure at commonly used ...

The clustered architecture, where the conventional monolithic register file is partitioned into several smaller register files, is one of the candidates for the future high performance processor architectures. The aggressive partitioning can reduce the access time of the register file. On the other hand, the partitioning makes losses of instructions per clock cycle due to communication among re...

BACKGROUND Most people experience back pain at some point during their lives. Reports suggest that core stability interventions in subjects with non-specific low-back pain may increase function, thus decreasing pain. Reliable and validated clinical tests are required for implementing adequate rehabilitation and for evaluating such interventions. OBJECTIVE This systematic literature overview s...

• Resource allocation in p2p file sharing is a public good problem – all peers benefit from the contribution of any single peer – downloading a file by one peer does not prevent another peer from downloading the same file (no congestion effects) – but contribution is costly – positive externality creates an incentive to free-ride on efforts of others – a peer’s incentive is to offer a few files...

Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...

We present a study on two key characteristics of human syntactic annotations: anchoring and agreement. Anchoring is a well known cognitive bias in human decision making, where judgments are drawn towards preexisting values. We study the influence of anchoring on a standard approach to creation of syntactic resources where syntactic annotations are obtained via human editing of tagger and parser...

The apparent diffuse coefficient (ADC) may correlate with the treatment response to chemotherapy/radiotherapy in solid tumors. Our aim was to determine the inter- and intra-observer reproducibility of ADC measurements in primary esophageal squamous cell carcinoma (ESCC). ADCs were blindly measured in 31 patients diagnosed with ESCC by two observers before treatment (pre-ADC) and after 5th fract...

Leveraging hypervisor for security purpose such as malware analysis has been well researched. There still remain two challenges for analyzing security incidents on virtual machine: real-time monitoring and semantic gap. First, current active monitoring methods need to be improved for real-time protection of virtual machine. Second, semantic gap between virtual machine and hypervisor poses a sig...

To study the structure of Iranian chemistry research, we identified 43 Iranian and international chemists who were highly cited in 7,682 Iranian chemistry publications (defined as an article with at least one Iranian author address) indexed in Science Citation Index (SciSearch) between 1990 and 2006, inclusive. We collected cocitation data for these authors from the entire SciSearch file (Dialo...
