Synthesis, Characterization, and Dynamic Behaviour of Triosmium Clusters Containing the Tridentate Ligand {Ph2PCH2CH2}2S (PSP)

Reaction of [Os3(CO)11(NCMe)] with bis-diphenylphosphanylethylene sulfide, {Ph2PCH2CH2}2S (PSP), leads to the formation of [Os3(CO)11(PSP)] and [{Os3(CO)11}2(-PSP)] in good yield. Similarly, treatment of [Os3(CO)10(NCMe)2] with PSP affords the cluster [Os3(CO)10(-PSP)], in which the two phosphanes of the PSP ligand coordinate to different osmium atoms of the same triosmium unit. Reaction of [Os3(C

New Technologies for DNA analysis-A review of the READNA Project.

The REvolutionary Approaches and Devices for Nucleic Acid analysis (READNA) project received funding from the European Commission for 4 1/2 years. The objectives of the project revolved around technological developments in nucleic acid analysis. The project partners have discovered, created and developed a huge body of insights into nucleic acid analysis, ranging from improvements and implementati

Prostate stem-cell antigen gene is associated with diffuse and intestinal gastric cancer in Caucasians: Results from the EPIC-EURGAST study

A genome-wide study performed in a Japanese population identified a strong association between SNP rs2294008 (Met1Thr) in the Prostate Stem Cell Antigen gene (PSCA) and diffuse-type gastric cancer (GC). This association was validated in different Asian populations, and, very recently, a study has been published in Caucasians. In this study, we analyzed the association between PSCA variation and GC

Passage-time moments and hybrid zones for the exclusion-voter model

We study the non-equilibrium dynamics of a one-dimensional interacting particle system that is a mixture of the voter model and the exclusion process. With the process started from a finite perturbation of the ground state Heaviside configuration consisting of 1’s to the left of the origin and 0’s elsewhere, we study the relaxation time τ, that is, the first hitting time of the ground state config

Simultaneous quantification of fat content and fatty acid composition using MR imaging.

Not only the fat content but also the composition of fatty acids (FAs) in stored triglycerides might be of interest in the research on nonalcoholic fatty liver disease and nonalcoholic steatohepatitis. In this study, a novel reconstruction approach is proposed that uses theoretical knowledge of the chemical structure of FAs to simultaneously quantify the fat fraction (FF) and the FAs composition (

Scheduling Tests for 3D Stacked Chips under Power Constraints

This paper addresses Test Application Time (TAT) reduction under power constraints for core- based 3D Stacked ICs (SICs) connected by Through Silicon Vias (TSVs). Unlike non-stacked chips, where the test flow is well defined by applying the same test schedule both at wafer sort and at package test, the test flow for 3D TSV-SICs is yet undefined. In this paper we present a cost model to find the op

Review of LCA studies of solid waste management systems - Part II: Methodological guidance for a better practice.

Life cycle assessment (LCA) is increasingly used in waste management to identify strategies that prevent or minimise negative impacts on ecosystems, human health or natural resources. However, the quality of the provided support to decision- and policy-makers is strongly dependent on a proper conduct of the LCA. How has LCA been applied until now? Are there any inconsistencies in the past practice

Serum markers in prostate cancer detection.

Prostate-specific antigen (PSA) testing provides significant benefits by reducing prostate cancer mortality, but also leads to important harms by detecting clinically insignificant cancers. Hence, there are urgent needs for complementary tools for middle-aged men with modest PSA elevations in blood. This review includes research on prostate cancer biomarkers in blood published from March 2013 thro

LKB1 signalling attenuates early events of adipogenesis and responds to adipogenic cues.

cAMP-response element-binding protein (CREB) is required for the induction of adipogenic transcription factors such as CCAAT/enhancer-binding proteins (C/EBPs). Interestingly, it is known from other tissues that LKB1 and its substrates AMP-activated protein kinase (AMPK) and salt-inducible kinases (SIKs), negatively regulate gene expression by phosphorylating the CREB co-activator CRTC2 and class

The MreB-like protein Mbl of S. coelicolor A3(2) depends on MreB for proper localization and contributes to spore wall synthesis.

Most bacteria with a rod-shape morphology contain an actin-like cytoskeleton consisting of MreB polymers which form helical spirals underneath the cytoplasmic membrane to direct peptidoglycan synthesis for elongation of the cell wall. In contrast MreB of Streptomyces coelicolor is not required for vegetative growth, but has a role in sporulation. Beside MreB, S. coelicolor encodes two further MreB

A review of the lichen family Parmeliaceae - history, phylogeny and current taxonomy.

The largest family of lichen-forming fungi, the Parmeliaceae, is reviewed. It includes 79 genera in current use and ca 2726 species, a large majority of which belong to one of five main clades: the parmelioid, cetrarioid, usneoid, alectorioid and hypogymnioid. However, 21 genera are positioned outside these clades, and four genera in current use still lack DNA- data. The family has been shown to b

Ligand Identification in Titanium Complexes Using X-ray Valence-to-Core Emission Spectroscopy

The identification of ligands in metalloorganic complexes is crucial for understanding many important biological and chemical systems. Nonresonant K beta valence-to-core X-ray emission spectroscopy (XES) has been demonstrated as a ligand identification technique which is complementary to other spectroscopies, such as X-ray absorption. In this study we show the K beta valence-to-core XES alongside

Experimental investigation on steady-state and transient performance of a self-excited induction generator

This study presents a novel approach to determine the steady-state performance of a self-excited induction generator (SEIG). The method gives an intuitive understanding of the effects of loading on the steady-state performance of the SEIG, without requiring any major mathematical effort. The steady-state no-load voltage of the SEIG is determined as the intersection between the generator no-load cu

The importance of gender and conceptualization for understanding the association between collective social capital and health: A multilevel analysis from northern Sweden

Growing research on social capital and health has fuelled the debate on whether there is a place effect on health. A central question is whether health inequality between places is due to differences in the composition of people living in these places (compositional effect) or differences in the local social and physical environments (contextual effects). Despite extensive use of multilevel approa
