Positively autocorrelated red environmental noise is characterized by a strong dependence of expected sample variance on sample length. This dependence has to be taken into account when assessing extinction risk under red and white uncorrelated environmental noise. To facilitate a comparison between red and white noise, their expected variances can be scaled to be equal, but only at a chosen time
For many years, antimuscarinic drugs have been the first-line pharmacological treatment for urgency, frequency, and urge incontinence, all symptoms of the disorder termed overactive bladder. Antimuscarinic treatment is not always effective and is associated with side-effects that limit its clinical use. The clinical significance of the effects of antimuscarinic drugs has been questioned lately. In
In the Western world advice given by breastfeeding consultants about the use of one or two breasts at each feed has resulted in apparently arbitrary changes over time. This study compared 1-month-old breastfed infants' reactions to single- and two-breast feeds in terms of restlessness, crying, sleeping, and frequency of feeds, wet diapers, and loose stools. Eighty mothers were randomly assigned at
AIM:To study the interactions between human gastric carcinoma cell (HGCC) and human vascular endothelial cell (HVEC), and the role of KDR in these interactions. METHODS:Antisense oligodexynucleotide(ASODN) specific to KDR gene was devised and added to the culture medium of HGCC and HVEC. After the action of ASODN, the proliferation of two cells was measured by MTT method. The role of KDR in regula
Aim To investigate the association between psychosocial conditions at work, unemployment and self-reported psychological health. Methods A cross-sectional postal questionnaire for the 2000 public health survey in Scania was administered to both working and unemployed people aged 18–64 years. Logistic regression models were used to investigate the association between psychosocial factors at work/u
In recent years, small businesses have received much attention from policy makers and researchers, in that these businesses are considered important for economic growth and job creation. At the same time small businesses are assumed to face major problems in securing long-term external finance, which is regarded as restraining their development and growth. Small business managers are assumed to us
According to our recent results the alveolar surface is formed by a coherent phase, not a monolayer as has been assumed earlier. This surface phase is a tetragonal organization of the lipid bilayer which seems to follow the CLP minimal surface structure. As lipid bilayers at cooling will undergo a transition from the liquid-crystalline type of structure into a solid state structure, we have follow
Structural properties of encapsidated flexible polyelectrolytes in viral capsids with dodecahedral charge distribution have been investigated by Monte Carlo simulations using a coarse-grained model. Several capsid charge distributions ranging from a homogeneous surface charge distribution (lambda=0) to a complete dodecahedral distribution (lambda=1) at constant total capsid charge and fixed radial
At night the Namib Desert spider Leucorchestris arenicola performs long-distance homing across its sand dune habitat. By disabling all or pairs of the spiders' eight eyes we found that homing ability was severely reduced when vision was fully abolished. Vision, therefore, seems to play a key role in the nocturnal navigational performances of L. arenicola. After excluding two or three pairs of eyes
Today there is ample evidence that the Cognitive Interview (CI) enhances witnesses' memory. However, less is known about how the CI affects eyewitnesses' confidence. To address this shortcoming we conducted a study analyzing how realism in confidence was affected by the CI. All participants (n = 79) were first shown a filmed kidnapping. After 2 weeks we interviewed one-third of the participants ac
A fast and stable numerical algorithm is presented for the elastostatic problem of a linearly elastic plane with holes, loaded at infinity. The holes are free of stress. The algorithm is based on an integral equation which is intended as an alternative to the classic Sherman–Lauricella equation. The new scheme is argued to be both simpler and more reliable than schemes based on the Sherman–Laurice
As negotiations on the post-2012 climate regime are now taking off, it is time to look back and assess the experiences of the clean development mechanism (CDM) to this date. The CDM has been subject to extensive discussion in academic literature during the last few years, and this article reviews that literature in order to sum up its main themes. A common assessment is that the current structure
We present a simple and controllable method for fabricating nano-apertures in a metal film using polystyrene nano-spheres as masks during the metal evaporation. We show how the processing conditions used during deposition of the spheres such as spin velocity, nano-sphere concentration and a reduction of the surface tension interplay and control the distribution of spheres. The fabrication method i
Information storage in neural circuits depends on activity-dependent alterations in synaptic weights, such as long-term potentiation (LTP) and long-term depression (LTD). Bidirectional synaptic plasticity endows synapses with mechanisms for rapid reversibility, but it remains unclear how it correlates with reversibility in behavioral learning and whether there is a universal synaptic memory mechan
Objective. To explore situations in which parents with an ill child consult a physician and to identify trigger factors for consultation. Design and settings. Qualitative interviews with parents of young children. Parents were asked to describe the situation in which the decision to contact the physician was made. Subjects. A total of 20 families selected from a birth cohort from Frederiksborg Cou
The next generation of telescopes, the Extremely Large Telescopes (ELTs), will have a multitude Of control loops to maintain nearly diffraction-limited performance in the presence of atmospheric turbulence and external disturbances, for instance from wind. Integrated simulation models combining structural and optical modeling together with control system modeling are efficient tools for prediction
Macroporous monolithic cryogels made from poly(vinyl alcohol) (PVA) with degree of saponification 87.7% have been prepared using a crosslinking reaction with glutaralclehyde under acidic conditions at subzero ternperatures. The porous structure of the monolithic cryogels from PVA (cryoPVA), analyzed using optical microscopy, scarinina electron microscopy, and environmental scanning electron micros
