New tailbiting encoders

In B tailbiting trellis encoder, the starting state of the encoder is set to the state at which the machine will be at the end of the encoded frame. By this means the probability of decoding error at the end of the frame can be kept low without the addition of termination bits and the consequent rate loss. We report on an extensive search for short and moderatelength convoluticinal encoders for ta

Effect of carbon dioxide and temperature on H2 producing cultures of the extreme thermophile, Caldicellulosiruptor saccharolyticus

Carbon dioxide could replace nitrogen gas as stripping gas for the production of H2 by the extreme thermophile, Caldicellulosiruptor saccharolyticus, provided that the pH is kept below 7.0. Above this pH, ≥77 mM sodium bicarbonate will be introduced as an extra salt burden to the culture. High concentrations of sugars and salts contribute each to the inhibition of growth and H2 production, which i

Collecting data for quality improvement and research in Swedish healthcare, and the individual patient's right and ability to protect their privacy

During the last decades, there has been continuous development of nationwide quality registries to assess healthcare and to do research in Sweden. An important background motive is the demographic transition resulting from an increasingly ageing population as one of the most important challenges of our time and a growing concern in many European countries and elsewhere. One condition for meeting t

Some comments on the effects of lower-mantle anisotropy on SKS and SKKS phases

Anisotropy in the lowermost few 100 km of mantle, or D" region, is indicative of deformation-induced alignment of crystals and/or inclusions of material, and as such offers insights into the dynamic nature of this region. Observations of shear-wave splitting in phases that transit this region provide constraints on such anisotropy. We investigate the effects of lower-mantle seismic anisotropy on S

Numerical and Experimental Studies on the Effects of Flow on Drop Formation in Cross-flow Membrane Emulsification

Membrane emulsification is a gentle process that produces emulsions with a narrow drop size distribution, which increases the stability of the emulsion. The dispersed phase is forced through the pores in a membrane and drops are formed at the other side of the membrane where a continuous phase, flowing along the membrane surface, sweeps away the forming drops. The growth and detachment of drops is

Future falls and/or near falls in people with Parkinson’s disease: Sensitivity and specificity of two retropulsion tests

Objective: To investigate the sensitivity and specificity of two retropulsion tests for identifying individuals with PD that will fall and/or experiencing near falls.Background: People with PD have an increased risk for falls and experiencing near falls. They are particularly unstable backwards, and different retropulsion tests exist. Item 30 of the Unified Parkinson’s Disease Rating Scale (UPDRS)
