An explanation is given for the paradoxical fact that, at low signal-to-noise ratios, the systematic feedback encoder results in fewer decoding bit errors than does a nonsystematic feedforward encoder for the same code. The analysis identifies a new code property, the d-distance weight density of the code. For a given d-distance weight density, the decoding bit error probability depends on the num

The importance of social circumstances for middle-age women’s general subjective well-being (SWB) was investigated in a representative sample of Swedish women, age 43 (N = 369). The results showed non-existent to moderate relationships between a number of social circumstances variables and general SWB. The strongest relationship was found between marital status and global life satisfaction. Being

Bacterial endotoxin is a potent inflammatory antigen abundant in the human intestine. Endotoxins circulate in the blood at low concentrations in all healthy individuals. Elevated levels of circulatory endotoxins may cause inflammation with the development of chronic disease, either affecting metabolism, neurological disease, or resistance to viral and bacterial infections. The most important endot

In order to reduce maritime transportation's greenhouse gas and pollutant emissions, marine engine manufacturers need to deepen the fundamental understanding of the injection and spray process. Two-dimensional unsteady-state Reynolds-averaged Navier-Stokes simulations were conducted to investigate evaporating high-pressure marine engine sprays, in which an injector with a nozzle diameter of 0.44 m

Osteoarthritis (OA) remains the most challenging arthritic disorder, with a high burden of disease and no available disease-modifying treatments. Symptomatic early-stage OA of the knee (the focus of this Review) urgently needs to be identified and defined, as efficient early-stage case finding and diagnosis in primary care would enable health-care providers to proactively and substantially reduce

We approach critically the assertion that a referendum ultimately defends the “traditional family,” by examining the articulation of anti-gender politics in Romanian parliamentary debates. We contribute theoretically by employing the concept of retrogressive mobilization in plebiscitary circumstances. We show that in Romania the contours of retrogressive mobilization transgress both the ideologica

Human rely profoundly on tactile feedback from fingertips to interact with the environment, whereas most hand prostheses used in clinics provide no tactile feedback. In this study we demonstrate the feasibility to use a tactile display glove that can be worn by a unilateral hand amputee on the remaining healthy hand to display tactile feedback from a hand prosthesis. The main benefit is that users

In an ampoule for a medicament the space accommodating the medicament is defined by an ampoule wall (1) a pierceable seal (5) closing one end of the ampoule and a piston (7) closing the other end of the ampoule. A metal containing fixation element (8) is secured to one of the parts defining the medicament accommodating space. A mixing element (9, 10) also containing a metal and having a density la

In this paper, beam diagnostic and monitoring tools developed by the MAX IV Operations Group are discussed. In particular, beam position monitoring and accelerator tunes visualization software tools, as well as tools that directly influence the beam quality and stability, are introduced. An availability and downtime monitoring application is also presented.

Graph neural networks for crystal structures typically use the atomic positions and the atomic species as input. Unfortunately, this information is not available when predicting new materials, for which the precise geometrical information is unknown. We circumvent this problem by replacing the precise bond distances with embeddings of graph distances. This allows our networks to be applied directl

Tunnel fire risk analysis are a useful tool to ensure adequate safety levels in tunnels. This report presents the work conducted to integrate a multi-zone modelling approach into a fire risk assessment tool, called ARTU. This work was performed to improve its fire modelling predictive capabilities compared to the currently adopted 1D fire modelling representation. This is deemed to allow for the u

The breaching of planetary boundaries and excessive extraction of natural resources requires a revisited approach to consumption and production. The concept of sufficiency, which advocates meeting human needs within the planetary limits by curbing excessive consumption levels, is gaining increasing attention. Businesses are drivers of consumption, yet they have been largely overlooked as potential

This article critically examines the approach of technical experts, including engineers, natural scientists, architects, planners, and other practitioners, who are attempting to create more sustainable forms of economic development, environmental protection, and social equity. The authors identify four principal characteristics of expertise–ontological assumptions, epistemological approaches, powe

Chronic breathlessness occurs across many different conditions, often independently of disease severity. Yet, despite being strongly linked to adverse outcomes, the consideration of chronic breathlessness as a stand-alone therapeutic target remains limited. Here we use data-driven techniques to identify and confirm the stability of underlying features (factors) driving breathlessness across differ
