An extensive literature is available on browsing preference for certain tree species. However, useful predictive tools for estimating the impact of deer on forests production and biodiversity can still be improved. A step in that direction is not only to rank preference among tree species but also to quantify the relative risk of being browsed. The foraging selectivity of moose was evaluated using

A foraging animal is often confronted with uncertainty of resource abundance. A Bayesian model provides the optimal forgaing policy when food occurrence is patchy. The solution of the Bayesian foraging policy requires elaborate calculations and it is unclear to what extent the policy could be implemented in a neural system. Here we suggest a network architecture of three neurones that approximatel

Non-targeted effect of BCG: Several recent studies suggest that BCG has beneficial non-targeted effects on general child survival in low-income countries. Studies of the effect of BCG on morbidity in humans are scarce; some found a positive effect of BCG and others show no effect. Non-targeted effects of vaccines-possible bias and confounding: The major argument against comparing vaccinated and un

In this paper an MMSE estimator of the complex shortime spectrum is considered for optimum noise reduction of speech. The correlation between frequency components is exploited to improve the estimation, especially of those components with low local SNR. Furthermore, by making use of both spectral envelope and time envelope, the estimator is able to suppress noise power infrequency domain and lime

ABSTRACT. This paper addresses the question of whether ‘main clause infinitival datives’ in Russian should be analyzed as oblique or ‘quirky’ subjects, in contrast to another type of subject-like datives in Russian, ‘I-nominals’. In particular, it examines a claim to this effect made by Moore and Perlmutter in a paper in Natural Language and Linguistic Theory (2000). By comparing the datives in qu

OBJECTIVES: Sleep deprivation has experimentally been shown to adversely influence glucose metabolism, endocrine function and sympathovagal balance in young men without known serious disease. We investigated the impact of sleep problems and resting heart rate in a large sample of self-reported, healthy middle-aged men and women on long-term mortality. METHODS: In all 22,444 men and 10,902 women pa

n one week of November 2000 and 2002, a diagnosis-antibiotic prescribing study was performed in general practice in 5 counties in Sweden. In total 11 515 patients were registered with a diagnosis of an infectious disease. Skin- and soft tissue infections were responsible for 10% of the visits and 13% of the antibioitc prescriptions. Older people (> 65 years) had more skin- and soft tissue infectio

Cells continuously export, import, and recycle molecules over the plasma membrane. Internalization, i.e. cellular import of extracellular material, is a fundamental process, which provides cells with nutrients and enables the immune cells of higher organisms to remove debris, sample their surroundings for antigens and to fight microbes. Moreover, internalization regulates complex cellular signalli

A comprehensive statistical model is described for ultrawideband (UWB) propagation channels that is valid for a frequency range from 3-10 GHz. It is based on measurements and simulations in the following environments: residential indoor, office indoor, builtup outdoor, industrial indoor, farm environments, and body area networks. The model is independent of the used antennas. It includes the frequ

The present doctoral thesis is a study of the problem of "variation" in relation to word-stress in Russian adjectives, in both their short and long forms. The stress variation in adjectival forms is investigated from various viewpoints, the main of which is the revelation of the basic processes of stress reorganisation in these groups of words and the establishment of main tendencies of adjectival

The estimated degree of carotid stenosis is decisive for the selection of patients who would benefit from surgical treatment. Carotid thrombendarterectomy is recommended in patients with symptomatic > or = 80 procent internal carotid artery stenosis (ECST method). Many vascular centers now often rely entirely on duplex ultrasonography to select the patients for carotid surgery. The results of a re

PURPOSE: To describe the response from multifocal electroretinography in branch retinal vein occlusion. DESIGN: Prospective observational case control series. METHODS: Multifocal electroretinography was recorded in 15 patients with temporal branch retinal vein occlusion and 21 control subjects using a visual evoked response imaging system. RESULTS: There were significant differences in mean amplit

An exactly solvable problem with energy dependent interaction is investigated in the present paper. The selfadjoint model operator describes the scattering problem for three one-dimensional particles. It is shown that this problem is equivalent to the diffraction problem in the sector with energy dependent boundary conditions. The problem is solved with the help of the Sommerfeld-Maluzhinetz repre

In this study, a qualitative perspective of how 13 women (aged 25 to 61 years) with spinal cord injury perceive the importance of social support for their participation in occupation is presented. The data were collected through repeated in-depth interviews and field notes, and the analysis used a grounded theory approach. The women needed both emotional and practical support, which was important
