Admission control for multicast routing with quality of service in ad hoc networks

Ad hoc networks, being able to organize themselves without user intervention, can easily provide their users with mobility, multimedia support and group communication. However, they have to combine quality of service (QoS) and multicast routing strategies. This article defines the resource management and admission control components of the ad hoc QoS multicast (AQM) routing protocol, which achieve

Ultrasound characteristics of different types of adnexal malignancies.

Objective. To describe ultrasound characteristics of adnexal malignancies, i.e., borderline ovarian tumors, primary invasive ovarian epithelial cancer stage 1, primary invasive ovarian epithelial cancer stages 2–4, rare types of malignancy, and metastatic tumors. Methods. In a prospective international study involving nine European ultrasound centers, 1066 women with a pelvic mass judged to be

Nanosecond to Microsecond Protein Dynamics Probed by Magnetic Relaxation Dispersion of Buried Water Molecules

Large-scale protein conformational motions on nanosecond – microsecond time scales are important for many biological processes, but remain largely unexplored because of methodological limitations. NMR relaxation methods can access these time scales if protein tumbling is prevented, but the isotropy required for high-resolution solution NMR is then lost. However, if the immobilized protein molecule

Tone 4 and Tone 3 discrimination in Modern Standard Chinese

Productions of tone 4 & tone 3 (mai/mai 'sell'/'buy') in comparable sentences suggests that although the two tones are realized in different ways by different speakers in different speech acts, some features are constant. Tone 3 is connected with a low pitch level throughout the second half of the vowel & tone 4 with a gradual fall over the main part of the vocalic segment. These observati

Electronic Doppler effect in resonant Auger decay of CO molecules upon excitation near a shake-up Pi resonance

We present an experimental observation of the electronic Doppler effect in resonant Auger spectra upon core excitation slightly above the carbon K edge of the CO molecule. Thus the electronic Doppler effect has been identified in above-threshold excitation, and in a transition of Pi symmetry. Ab initio calculations of the potential energy curves of the relevant states of CO and the wave packet tec

The menopause revisited

The continuing growth of female life expectancy has resulted in a marked increase of women in years beyond the menopause. Women can nowadays expect to live one-third of their lives in a potential hormonal deficiency state. Women over 50 comprise 17% of the total population of any country in the modern western world. Any decision regarding their health issues will have a great impact on our limited

The meaning and significance of clinical group supervision and supervised individually planned nursing care as narrated by nurses on a general team psychiatric ward

By interviewing 22 psychiatric nurses, the present study aimed to reveal the meaning and significance of systematic clinical group supervision and supervised individually planned nursing care, using latent content analysis. The interpreted meaning was 'confronting the complexity of ongoing life in daily nursing care' and the interpreted significance was 'strengthening the foundation for nursing ca

Methotrexate Versus Cyklosporine in Psoriasis: effectiveness quality of life and safety. A randomized controlled trial

Background When this study was initiated, no previous studies comparing methotrexate and ciclosporin for moderate to severe plaque psoriasis had been performed. Objectives To compare the effectiveness, quality of life and side-effects of methotrexate and ciclosporin treatments in a context reflecting normal clinical practice. Methods Eighty-four patients with moderate to severe plaque psoriasis

Genomics of parasitic and symbiotic fungi

Complete and partial genome sequence information is underway in several parasitic and symbiotic fungi that infect humans, other animals and plants. Comparative analyses of these sequences will provide new insights into the genomic plasticity and evolution of parasitism and mutualism in fungi.

Spurious solutions and boundary conditions in k center dot p theory

It is well known that the origin of one type of spurious solutions in multiband k(.)p theory is the failure to restrict the Fourier coefficients of the envelope functions to the first Brillouin zone. Often, the set of differential equations obtained is supplemented with interfacial boundary conditions derived by integrating the differential equations across the interface; however, this leads to a

Conjugated linoleic acid increased C-reactive protein in human subjects

We previously showed that conjugated linoleic acid (CLA) increases 15-keto-dihydro-prostaglandin F-2 alpha, a marker for cyclooxygenase-mediated lipid peroxidation and thus an indicator of cyclooxygenase-mediated inflammation. The aim of the present study was to investigate the effects of CLA on other indicators of inflammation in human subjects, including C-reactive protein, TNF-alpha, TNF-alpha

Microwave-induced hyperthermia and radiotherapy in human superficial tumours: clinical results with a comparative study of combined treatment versus radiotherapy alone

Eighty-five evaluable superficial recurrent malignant tumours, mainly adenocarcinomas (78 per cent), in 38 patients were treated with either combined local hyperthermia (41-45 degrees C for four sessions) and low dose radiotherapy (30.0 Gy) or the same low dose radiotherapy alone. The treatment was given for two weeks. Hyperthermia was induced externally with 2450 MHz or 915 MHz microwaves. Totall

Using the functional response to determine the nature of unequal interference among foragers

The food intake rate of foragers may be reduced as a result of interference, which may be asymmetric among individuals and occur as a result of intimidation, direct aggression or filtering. It is important to distinguish among these types of interference, because each can have different consequences for individuals, foraging groups and populations. We demonstrate the application of the functional

Design of recombinant antibody microarrays for complex proteome analysis: Choice of sample labeling-tag and solid support

Antibody-based microarray is a novel technology with great potential within high-throughput proteomics. The process of designing high-performing antibody (protein) microarrays has, however, turned out to be a challenging process. In this study, we have developed further our human recombinant single-chain variable-fragment (scFv) antibody microarray methodology by addressing two crucial technologic
