Context. Development of safety-critical systems is mostly governed by process-heavy paradigms, while increasing demands on flexibility and agility also reach this domain. Objectives. We wanted to explore in more detail the industrial needs and challenges when facing this trend. Method. We launched a qualitative survey, interviewing engineers from four companies in four different industry domains.

Hepatitis B virus (HBV) infection is one of most common viral infections worldwide. While chronic HBV infection has been shown consistently to be associated with hepatocellular carcinoma, data on associations with cancers at other sites are limited. In this study a total of 10,197 patients were diagnosed with chronic HBV infection in Sweden, and they were retrieved from the nationwide Swedish Hosp

Topological insulators are a class of quantum materials in which time-reversal symmetry, relativistic effects and an inverted band structure result in the occurrence of electronic metallic states on the surfaces of insulating bulk crystals. These helical states exhibit a Dirac-like energy dispersion across the bulk bandgap, and they are topologically protected. Recent theoretical results have sugg

The adsorption to hydrophilic silica surfaces in relation to the bulk phase behavior was investigated by in situ null ellipsometry and bulk turbidity measurements for four cationic copolymers of varying hydrophobicity in mixtures with anionic surfactant sodium dodecylsulfate (SDS). The purpose was to reveal the effect of polyion hydrophobicity on the association with surfactant at surfaces and in

We show how one can back out implied forward volatility term structures from credit default swap spreads. Such forward stock volatility term structures are useful for instance in forward start option pricing. We find the term structure to be downward-sloping, and the credit market's volatility forecasts tend to vary more across time than across maturities. Long-term volatility expectations, in tur

The synthesis of an orthogonal topological pentamer analogue of helicene is presented. This analogue forms a tubular structure with its aromatic systems directed parallel to the axis of propagation, which creates a cavity with the potential to function as a host molecule. The synthetic strategy reported, based on a series of repeating Friedländer condensations that utilize pyrido[3,2-d]pyrimidine

Back-to-back hadron pair yields in d + Au and p + p collisions at root S-NN = 200 GeV were measured with the PHENIX detector at the Relativistic Heavy Ion Collider. Rapidity separated hadron pairs were detected with the trigger hadron at pseudorapidity vertical bar eta vertical bar < 0: 35 and the associated hadron at forward rapidity (deuteron direction, 3.0< eta < 3.8). Pairs were also detected

We report a rapid and highly efficient approach to generate mice in which the hematopoietic system is derived from embryonic stem (ES) cells. We show that ES cells injected into blastocysts from the c-kit deficient W41/W41 mouse strain have a clear advantage over the W41/W41 blastocyst-derived inner cell mass cells in founding the hematopoietic system. Fetal liver HSCs from W41/W41 blastocyst comp

Research regarding expressive language performance in children born with cleft palate is sparse. The relationship between articulation/phonology and expressive language skills also needs to be further explored.

Soil samples were collected in six South American countries in a total of 71 different 1 ha forest plots across the Amazon Basin as part of the RAINFOR project. They were analysed for total and exchangeable cations, C, N, pH with various P fractions also determined. Physical properties were also examined and an index of soil physical quality proposed. A diverse range of soils was found. For the we

Santiago was one of the first cities outside the OECD to implement a tradable permit program to control air pollution. This article looks closely at the program's performance over the past 10 years, stressing its similarities and discrepancies with trading programs implemented in developed countries and analyzing how it has reacted to regulatory adjustments and market shocks. Studying Santiago's e

Aims: To explore whether gender differences in the Scandinavian Cystic Fibrosis (CF) patients exist in the areas of key clinical parameters, complications, and medication. Methods: Cross-sectional data on 890 (416 female) pancreatic insufficient CF patients were evaluated regarding chronic infection, body mass index, lung function, medication, and diabetes, as well as data of Pseudomonas infection

Energy security is one of the main drivers of energy policies. Understanding energy security implications of long-term scenarios is crucial for informed policy making, especially with respect to transformations of energy systems required to stabilize climate change. This paper evaluates energy security under several global energy scenarios, modeled in the REMIND and WITCH integrated assessment mod

More than 4 orders of magnitude of cavity-linewidth narrowing in a rare-earth-ion-doped crystal cavity, emanating from strong intracavity dispersion caused by off-resonant interaction with dopant ions, is demonstrated. The dispersion profiles are engineered using optical pumping techniques creating significant semipermanent but reprogrammable changes of the rare-earth absorption profiles. Several

We present the first evidence that cats experience visual illusions and that a non-human animal can see illusory motion. In three videos we show cats reacting with hunting behavior when watching the Rotating Snakes illusion. This is taken to mean that cats see illusory motion in this image due to the propensity of cats to pursue movement. This is further supported by a survey where 29% of the resp

Purpose: Identify factors predictive for severe self-reported disability in patients with rheumatoid arthritis. Methods: Patients (n = 1910) were sent a questionnaire 5-18 years after disease onset. Outcomes were the Health Assessment Questionnaire (HAQ), Rheumatoid Arthritis Outcome Score (RAOS) and physical activity. The tertile of patients most affected by the disease were compared to those les

We studied the impact of a family history of type 2 diabetes on physical fitness, lifestyle factors and diabetes-related metabolic factors. The Prevalence, Prediction and Prevention of Diabetes (PPP)-Botnia study is a population-based study in Western Finland, which includes a random sample of 5,208 individuals aged 18 to 75 years identified through the national Finnish Population Registry.
