This paper illustrates a novel method to analyze artificial neural networks so as to gain insight into their internal functionality. To this purpose, we will show analysis results of some feed-forward-error-back-propagation neural networks for image processing. We win describe them in terms of domain-dependent basic functions, which axe, in the case of the digital image processing domain, differen

An in-house-made alignment system for deep X-ray lithography is presented that features low costs, low weight and little demand in space. Synchrotron radiation illuminates alignment marks on mask and substrate. The radiation transmitted through these alignment marks is detected by X-ray-sensitive diodes. The mask is fixed to the vacuum chamber, whereas the substrate is mounted on a six-axis kinema

We recommend prophylaxis in haemophilic children with an inhibitor as a way of preventing the musculoskeletal impairment that is likely to affect them. This approach has been used for children without inhibitors with excellent results. If prophylaxis is not feasible, we suggest that intensive on-demand treatment should be given. Two agents, recombinant activated FVII (rFVIIa) and activated prothro

Stellar clusters are highly useful as tools for determination of distances, ages and abundances of heavy elements of galaxies, also at larger distances. Their utility for these purposes has, so far, been severely limited, mainly due to image crowding. The introduction of Extremely Large Telescopes (ELTs) with full adaptive optics (AO) and near diffraction limited performance should imply a drastic

Many models currently discussed in PR studies lack a supporting meta-theory of what managing communication is about, and consequently paint a simplistic picture of what communicating with publics or managing phenomena such as reputation actually means. While it is common to speak of “building” trust or “constructing” images, “cultivating” seems a more appropriate metaphor. Publics are complex, dyn

The capillary filtration coefficient (CFC) is assumed to reflect both microvascular hydraulic conductivity and the number of perfused capillaries at a given moment (precapillary sphincter activity). Estimation of hydraulic conductivity in vivo with the CFC method has therefore been performed under conditions of unchanged vascular tone and metabolic influence. There are studies, however, that did n

How do different levels of sibling competition affect nestling growth strategies? We investigated this through the effect of different levels of per capita feeding rate on the average growth rate of nestlings and on individual growth strategies within broods. To manipulate sibling competition, we transferred marsh tit nestlings between nests creating broods with fewer (reduced) or more (enlarged)

Purpose: The aim of this study was to validate the conceptual definitions of accessibility and usability, and to explore differences between objective accessibility assessments and subjective ratings of usability in different client groups. Method: The Housing Enabler and the Usability in My Home instruments were used for 131 persons above 18 years of age, living in ordinary housing and receiving

Objective: The objective was to analyse relationships between inspiratory and expiratory static and dynamic elastic pressure-volume (P-el/V) curves in healthy pigs. Design: The modulated low flow method was developed to allow studies also of the expiratory P-el/V curves. Static P-el/V (P-el,P-st/V) and dynamic P-el/V (P-el,P-dyn/V) loops were studied in healthy pigs. Setting: Animal research labor

Objectives: The strategies used to support smoking cessation among quitters were investigated according to year of smoking cessation and sociodemographic characteristics. Methods: The 2004 public health survey in Skane, Sweden, is a cross-sectional study. A total of 27 757 people aged 18-80 answered a postal questionnaire. The participation rate was 59%. Different strategies to support smoking ces

Autumn migration of adult Eurasian hobbies Falco subbuteo from Europe to southern Africa was recorded by satellite telemetry and observed routes were compared with randomly simulated routes. Two non-random features of observed routes were revealed: (i) shifts to more westerly longitudes than straight paths to destinations and (ii) strong route convergence towards a restricted area close to the equ

The aim of the present study was to investigate whether current smoking, ex-smoking, or amount of current smoking among postmenopausal women was associated with plasma levels of testosterone, and rostenedione, and DHEAs. About 65,000 women in Sweden have participated in two population-based prospective cohort studies where blood samples were collected at baseline, and information on life-style, re

OBJECTIVES To assess the effect of nocturia on productivity, vitality and utility in a selected group of professionally active individuals with nocturia, compared with matched controls, and investigate the effect of symptom severity, to test the hypothesis that lack of sleep caused by frequent sleep interruptions could reduce an individuals' daytime energy and activity levels. SUBJECTS AND METHODS

This study compared the realism of witnesses’ confidence judgments of their own recall elicited in either the Cognitive Interview (CI) or the Structured Interview (SI). Calibration methodology was used to analyze the realism of the confidence judg­ments. Participants (N = 56) were interviewed about their observations of a staged crime and returned two weeks later to assess their confidence in the

Soft tissue sarcomas often present as large and histopathologically heterogenous tumors. Proliferation has repeatedly been identified as a prognostic factor and immunostaining for Ki-67 represents the most commonly used proliferation marker. There is, however, a lack of consensus on how to evaluate Ki-67 staining regarding optimal cut-off levels, selection of tumor areas, and the number of tumor c

The triptan drugs provide effective migraine relief for many people. nevertheless, a substantial number of migraine-affected individuals are unresponsive to triptans, and such therapy can also lead to an array of adverse effects. A new class of antimigraine drugs, currently undergoing clinical trials, could offer hope to those for whom triptan medication is unsuitable.
