A Home-Proxy Based Wireless Internet Framework in Supporting Mobility and Roaming of Real-Time Services

Due to the lack of support in mobility and quality of service, today's IF-based networks have some inherent limitations: for delivering multimedia services in a mobile environment. In the past few years, these issues have been addressed in the research community and the resulting techniques: are being standardised. However, these development have been done in isolation and become incompatible with

On CFD-Analysis of Heat Transfer of a Heavy-Duty Diesel Engine

In this work, a heavy-duty diesel engine was studied by employing CFD simulations on a closed volume engine segment. These simulations were used to evaluate both the effects from certain parameters on the wall heat transfer, and to examine how reduction of heat transfer would effect the engine performance and emission levels. In the first study, an initial investigation concerning the in- cylinde

Ezrin expression predicts local recurrence and development of metastases in soft tissue sarcomas.

Background Ezrin is a cytoskeletal protein involved in tumour growth and invasion. Ezrin expression has been suggested to play a role in metastasis in paediatricosteosarcoma and rhabdomyosarcoma. Aim To evaluate the prognostic role of ezrin in a large series of soft tissue sarcoma of the extremities and trunk wall. Methods Ezrin expression was evaluated by immunohistochemistry on tissue microarray

Arsenic metabolism is influenced by polymorphisms in genes involved in one-carbon metabolism and reduction reactions.

OBJECTIVES: The susceptibility to arsenic (As)-induced diseases differs greatly between individuals, probably to a large extent due to genetic differences in arsenic metabolism. The aim for this study was to identify genetic variants affecting arsenic metabolism. METHODS: We evaluated the association between urinary metabolite pattern and polymorphisms in three gene-groups related to arsenic metab

Insulin secretion is highly sensitive to desorption of plasma membrane cholesterol.

Cholesterol-rich clusters of SNARE (soluble NSF attachment protein receptor) proteins have been implicated as being important for exocytosis. Here we demonstrate the significance of cholesterol for normal biphasic insulin secretion in mouse beta cells by removal of cholesterol from the plasma membrane using methyl-beta-cyclodextrin (MBCD). Maximal inhibition of insulin secretion in static incubati

Social capital, political trust and self rated-health: a population-based study in southern Sweden.

AIM: To investigate the association between political trust (an aspect of institutional trust) and self-rated health, taking generalized (horizontal) trust in other people into account. METHODS: The 2004 public health survey in Skåne is a cross-sectional postal questionnaire study answered by 27,963 respondents aged 18-80 years, yielding a 59% response rate. A logistic regression model was used to

Next generation sequencing reveals that HLA-DRB3, -DRB4 and -DRB5 may be associated with islet autoantibodies and risk for childhood type 1 diabetes.

The possible contribution of HLA-DRB3, -DRB4 and -DRB5 alleles to type 1 diabetes risk and to autoantibodies against insulin (IAA), GAD65 (GADA), IA-2 (IA-2A) or ZnT8 against either of the three amino acid variants, R, W or Q at position 325 (ZnT8RA, ZnT8WA, and ZnT8QA, respectively) at clinical diagnosis is unclear. Next generation sequencing (NGS) was therefore used to determine all DRB alleles

Herstory revisited

This text deals with a very particular dilemma: how should I, a post-linguistic-turn gender historian, deal with the reality that women are constantly excluded from the continuing writing of the past (or are silenced in the history that is played out in front of my eyes) without falling back on the herstory tradition that the majority of us academics say we have left behind? The problem is discuss

Takras avslöjar allvarliga brister

SP har etablerat en databas med 180 rasade eller skadade tak. Det framgår, att det var övervägande stål- och träkonstruktioner, som hade rasat. Endast en skadad betongkonstruktion rapporterades. Byggnadernas ålder spänner över cirka 100 år, men 60 % är uppförda från 1980 och framåt. Taken är förhållandevis flacka. Ca 30 % är lantbruksbyggnader. De dominerande rasorsakerna är dimensioneringsfel och

Iliocaval vein stenting: Long term survey of postthrombotic symptoms and working capacity.

To evaluate the long term effect on lower extremity function and working capacity after stenting of iliocaval vein segments for acute deep venous thrombosis (DVT) or chronic venous occlusive disease. During a 14 year period from November 1994 to October 2008, 114 patients with median age 36 (interquartile range [IQR], 27-48) years, 72 (63%) women, 72 (63%) with hypercoagulable disorders, with acut

Live Memory Analysis for Garbage Collection in Embedded Systems

Real-time garbage collection is essential if object-oriented languages (in particular, Java) are to become predictable enough for real-time embedded systems. Although techniques for hard real-time garbage collection exist, they are based on estimations of the maximum amount of referenced (live) memory. Such estimations may be difficult to derive manually for complex programs.We present techniques

A general strategy-proof fair allocation mechanism revisited

This paper revisits the fair and optimal allocation mechanism (Sun and Yang, Economics Letters 81:73-79, 2003) and demonstrates that it is coalitionally strategy-proof. The proof is valid for general preferences, it is simple and it is short.
