The masses of the nuclides Rn203-207 and Ra-213 were measured directly for the first time with the Penning-trap mass spectrometer SHIPTRAP at GSI Darmstadt. The results confirm the previously determined mass values. The mass uncertainties for Rn-205 and Ra-213 were significantly reduced. The results are relevant for the investigation of the nuclear shell structure between N = 82 and N = 126. As an

Polyphenolic substances, such as flavonoids, attract considerable interest due to their ability to act as antioxidants. The vast majority of studies published deal with the nutritional, biochemical, or chemical structure aspects of these substances while few reports exist on the physico-chemical properties as well as solution behavior of the substances. In this article we report on the precipitati

There are many ways to define the distance between two protein structures, thus assessing their similarity. Here, we investigate and compare the properties of five different distance measures, including the standard root-mean-square deviation (cRMSD). The performance of these measures is studied from different perspectives with two different protein models, one continuous and the other discrete. U

We consider two interrelated tasks in a synchronous n-node ring: distributed constant colouring and local communication. We investigate the impact of the amount of knowledge available to nodes on the time of completing these tasks. Every node knows the labels of nodes up to a distance r from it, called the knowledge radius. In distributed constant colouring every node has to assign itself one out

We examine a recently proposed symmetry/condition by Friedberg and Lee in the framework where three right-handed neutrinos are added to the spectrum of the three-family Minimal Standard Model. It is found that the right-handed neutrinos are very special, with respect to this symmetry. In the symmetry limit the neutrinos are massless and that may be a hint about why they are light. Imposed as a con

The interaction between fungal laccases from Trametes basidiomycetes and different lignins has been studied using electrochemical and chromatographic methods. The kinetic parameters for the oxidation reaction of hydroquinone and for Kraft lignin by molecular oxygen catalysed by Trametes hirsuta laccase have been investigated. Polymerisation of lignin by laccase was shown. The process was independe

The human occupational/activity pattern is a product of person–occupation–environment interaction, it is of importance to explore all these factors to understand the daily occupational pattern among persons with schizophrenia. This study aimed to describe the time use of 10 persons with schizophrenia, reflecting the participants’ daily occupations, social and geographical environments, and emotion

In this paper we investigate the problem of embedding a number of points given certain (but typically not all) inter-pair distance measurements. This problem is relevant for multi-dimensional scaling problems with missing data, and is applicable within anchor-free sensor network node calibration and anchor-free node localization using radio or sound TOA measurements. There are also applications wi

Spondyloarthritis (SpA) is a group of interrelated inflammatory rheumatic diseases with the sub-diagnoses ankylosing spondylitis (AS), psoriatic arthritis (PsA), arthritis-associated inflammatory bowel disease (Aa-IBD), undifferentiated SpA (USpA), where stiffness and pain are key symptoms. Insidious onset back pain, morning stiffness, waking up at night, and improvement from exercise are common c

The partial glutamate antagonist amantadine is currently used in clinical practice, to reduce dyskinesia developing as a side-effect of levodopa treatment in patients suffering from Parkinson's disease (PD). This study was aimed at evaluating the antidyskinetic effect of another glutamate antagonist, memantine.

Background: The two essential features of minor depression are that it has fewer symptoms than major depression and that it is less chronic than dysthymia. This study describes the clinical features and functioning of outpatients with minor depression. Methods: Subjects with minor depression (with and without a prior history of major depression) were recruited through clinical referrals and commun

Monocytes and macrophages are part of the body’s first line of defense, eliminating pathogens by phagocytosis or by releasing a broad array of inflammatory mediators, such as cytokines, chemokines and proteases. In humans, three subsets of monocytes are described with seemingly different functions. The classical (CD14++CD16-) monocytes, the intermediate (CD14++CD16+) monocytes and the non-classica

Based on the Constructal Theory, parallel-flow and counterflow microchannels heat sinks with bifurcations are put forward to manage the temperature nonuniformity and further reduce the temperature of microchannel heat sinks bottom plates. Several models with different lengths of bifurcations are designed, and the corresponding laminar fluid flow and heat transfer of all models have been investigat

We have experimented with different SOM-based architectures for bio-inspired self-organizing texture and hardness perception systems. To this end we have developed a microphone based texture sensor and a hardness sensor that measures the compression of the material at a constant pressure. We have implemented and successfully tested both monomodal systems for texture and hardness perception, bimoda

Asymmetric In0.53Ga0.47As MOSFETs with different regrown contacts at source (In0.53Ga0.47As) and drain (InP) have been developed. By introducing a wider bandgap material, InP as drain electrode, higher self-gain g(m)/g(d) has been obtained with reduced output conductance g(d) and improved break-down voltage V-bd. For L-g=100nm, a high oscillation frequency f(max)= 270GHz has been obtained using an
