Application of re-estimation in re-planning of software product releases

Context: Re-planning of product releases is a very dynamic endeavor and new research methods or improvements of existing methods are still required. This paper explores the role of re-estimation in the re-planning process of product releases. Objective: The purpose of this study is to analyze effects of defect and effort re-estimation in the process of release re-planning. In particular, two ques

Emphysema diagnosis using X-ray dark-field imaging at a laser-driven compact synchrotron light source

In early stages of various pulmonary diseases, such as emphysema and fibrosis, the change in X-ray attenuation is not detectable with absorption-based radiography. To monitor the morphological changes that the alveoli network undergoes in the progression of these diseases, we propose using the dark-field signal, which is related to small-angle scattering in the sample. Combined with the absorption

How can meaningfulness be created in the design process? The case of young disabled users.

It is well-known that the participation in a design process can be experienced as being so meaningful that the participation in itself overshadows even the result of that process. The participants in this design project represent a user group that often use products in which functional value is pre-eminent: people with disabilities. Thereby special attention has been given to the concepts of stigm

The effects of cereal additives in low-fat sausages and meatballs. Part 2: Rye bran, oat bran and barley fibre.

Rye bran, oat bran and barley fibre have been compared as additives in low-fat sausages and meatballs. The water/protein ratio and starch content were constant to allow direct comparisons. Oat bran was the best alternative in low-fat sausages due to its gelling ability upon heating. These sausages exhibited low process (0.9%) and frying losses (10.9%), and high values of firmness (11.0N) and senso

Differences in Speed and Duration of Bird Migration between Spring and Autumn.

Abstract It has been suggested that birds migrate faster in spring than in autumn because of competition for arrival order at breeding grounds and environmental factors such as increased daylight. Investigating spring and autumn migration performances is important for understanding ecological and evolutionary constraints in the timing and speed of migration. We compiled measurements from tracking

Clock shifts in a Fermi gas interacting with a minority component: A soluble model

We consider the absorption spectrum of a Fermi gas mixed with a minority species when majority fermions are transferred to another internal state by an external probe. In the limit when the minority species is much more massive than the majority one, we show that the minority species may be treated as static impurities and the problem can be solved in closed form. The analytical results bring out

Patch testing with own cosmetics-a prospective study of testing and reporting of adverse effects to the Swedish Medical Products Agency.

Background: The Swedish Medical Products Agency (MPA) provides a voluntary reporting system for adverse reactions to cosmetics. However, the reporting is sparse, and the products involved are sometimes difficult to identify. Objectives: To investigate how often patients referred for patch testing were tested with the cosmetic products that they had been using themselves, and to improve the repor

Osteopontin deficiency dampens the pro-atherogenic effect of uraemia

Uraemia is a strong risk factor for cardiovascular disease. Osteopontin (OPN) is highly expressed in aortas of uraemic apolipoprotein E knockout (E KO) mice. OPN affects key atherogenic processes, i.e. inflammation and phenotypic modulation of smooth muscle cells (SMCs). We explored the role of OPN on vascular pathology in uraemic mice. Uraemia was induced by 5/6 nephrectomy in E KO and in OPN and

Carrier control and transport modulation in GaSb/InAsSb core/shell nanowires

We report transport studies of GaSb/InAs core/shell nanowires. It is shown that with increasing InAs shell thickness, it is possible to tune the carrier concentrations and transport in the structures from p-type (core-dominated) to n-type (shell dominated). For nanowires with an intermediate shell thickness (5-7 nm), we show that the transport is ambipolar, such that an applied top-gate potential

Cartographic Design Matters : A Comparison of Thematic Polygon Design

The number of web services providing cartographic data is increasing. A main challenge is to enable a user to combine these services, not only from a technical perspective, but also from a cartographic one. One common use case for these services is to create mashups based on thematic polygons on top of background maps. In this study we compare four cartographic designs of thematic polygons: only b

Combined treatment of relaxation and fluctuation dynamics in the calculation of two-dimensional electronic spectra.

While the theoretical description of population transfer subsequent to electronic excitation in combination with a line shape function description of vibrational dynamics in the context of 2D-spectroscopy is well-developed under the assumption of different timescales of population transfer and fluctuation dynamics, the treatment of the interplay between both kinds of processes lacks a comprehensiv

Adaptation of reproductive phenology to climate change with ecological feedback via dominance hierarchies.

Phenological shifts belong to the most commonly observed biological responses to recent climate change. It is, however, often unclear how these shifts are linked to demography and competitive interactions. We develop an eco-evolutionary model to study adaptation of timing of reproduction in organisms with social dominance hierarchies. We focus on residential birds with winter flocks, where success

Bioinspired composites from cross-linked galactoglucomannan and microfibrillated cellulose: Thermal, mechanical and oxygen barrier properties.

In this study, new wood-inspired films were developed from microfibrillated cellulose and galactoglucomannan-lignin networks isolated from chemothermomechanical pulping side streams and cross-linked using laccase enzymes. To the best of our knowledge, this is the first time that cross-linked galactoglucomannan-lignin networks have been used for the potential development of composite films inspired

Factors Associated with Remission of Eczema in Children: a Population-based Follow-up Study.

The aim of this study was to analyse factors associated with remission of atopic dermatitis (AD) in childhood. A population-based AD cohort of 894 children aged 1-3 years from a cross-sectional baseline study in 2000 was followed up in 2005. The association between remission, background, health, lifestyle, and environmental variables was estimated with crude and multivariable logistic regression.

Post-Relapse Survival in Patients With Ewing Sarcoma

BackgroundPost-relapse survival (PRS) was evaluated in patients with Ewing sarcoma (EWS) enrolled in chemotherapy protocols based on the use of high-dose chemotherapy with busulfan and melfalan (HDT) as a first-line consolidation treatment in high-risk patients. ProcedureEWS patients enrolled in ISG/SSG III and IV trials who relapsed after complete remission were included in the analysis. At recur

Endothelial ALK1 Is a Therapeutic Target to Block Metastatic Dissemination of Breast Cancer.

Exploration of new strategies for the prevention of breast cancer metastasis is justifiably at the center of clinical attention. In this study, we combined a computational biology approach with mechanism-based preclinical trials to identify inhibitors of activin-like receptor kinase (ALK) 1 as effective agents for blocking angiogenesis and metastasis in breast cancer. Pharmacologic targeting of AL

Ringspännen/hästskoformade spännen, gåvogivning och kontakterna mellan Mälarområdet och sydvästra Finland under vikingatid

The article deals with the contacts between the Mälaren region, Sweden, and south western Finland during the Viking Age. The material studied is pegged penannular brooches, an artefact with a core area in Finland. Earlier, these brooches when found outside Finland, have been interpreted as representing weapon bearing migrated Finnish men. Since the material from the Mälaren region does not support
