In the case of an attack by a "dirty bomb" with cesium-137 there is a risk of internal contamination. The excretion of cesium-137 can be enhanced by Prussian Blue (PB), and thus the committed effective dose be reduced. We analyzed the benefit and costs of PB decorporation treatment. We simulated the reduction of the radiological dose by PB treatment after cesium-137 incorporation by inhalation. The saving of life time was quantified using the monetary "value of a statistical life" (VSL). Treatment costs were based on the market price of PB in Germany...

Motivation: Metagenomic read classification is a critical step in the identification and quantification of microbial species sampled by high-throughput sequencing. Although many algorithms have been developed to date, they suffer significant memory and/or computational costs. Due to the growing popularity of metagenomic data in both basic science and clinical applications, as well as the increasing volume of data being generated, efficient and accurate algorithms are in high demand. Results: We introduce MetaOthello, a probabilistic hashing classifier for metagenomic sequencing reads...

Summary: The decreasing cost in high-throughput technologies led to a number of sequencing projects consisting of thousands of whole genomes. The paradigm shift from exome to whole genome brings a significant increase in the size of output files. Most of the existing tools which are developed to analyse exome files are not adequate for larger VCF files produced by whole genome studies. In this work we present VCF-Explorer, a variant analysis software capable of handling large files. Memory efficiency and avoiding computationally costly pre-processing step enable to carry out the analysis to be performed with ordinary computers...

In an environment of constrained resources, policymakers must identify solutions for financing and delivering health services that are efficient and sustainable. However, such solutions require that policymakers understand the complex interaction between household utilization patterns, factors influencing household medical decisions, and provider performance. This study examined whether and under what conditions out-of-pocket, transportation, and time costs influenced Kenyan households' choice of medical provider for childhood diarrhoeal illnesses...

Summary: Next-generation sequencing technologies have become the most powerful tool to discover genetic variants associated with human diseases. Although the dramatic reductions in the costs facilitate the use in the wet-lab and clinics, the huge amount of data generated renders their management by non-expert researchers and physicians extremely difficult. Therefore, there is an urgent need of novel approaches and tools aimed at getting the 'end-users' closer to the sequencing data, facilitating the access by non-bioinformaticians, and to speed-up the functional interpretation of genetic variants...

Motivation: Accurate and dense linkage maps are useful in family-based linkage and association studies, quantitative trait locus mapping, analysis of genome synteny and other genomic data analyses. Moreover, linkage mapping is one of the best ways to detect errors in de novo genome assemblies, as well as to orient and place assembly contigs within chromosomes. A small mapping cross of tens of individuals will detect many errors where distant parts of the genome are erroneously joined together...

Christoph Bösel, Herbert Gross
In beam shaping applications, the minimization of the number of necessary optical elements for the beam shaping process can benefit the compactness of the optical system and reduce its cost. The single freeform surface design for input wavefronts, which are neither planar nor spherical, is therefore of interest. In this work, the design of single freeform surfaces for a given zero-étendue source and complex target irradiances is investigated. Hence, not only collimated input beams or point sources are assumed...

There have been numerous methods for accessing the reflectance spectra; some methods enable one to obtain the spectra directly, such as using a spectrophotometer, hyper-spectral camera, and so forth. Even though the accuracy by which the spectra are obtained can be very high, the high price of these methods could pose an obstacle. On the other hand, there has been an interest in estimation of the spectral reflectance from colorimetric information that is more easily attainable; the accuracy in this case might not be as high but these methods are the most cost efficient...

BACKGROUND: Mutations in the BRAF gene have been strongly associated with failure in cancer treatment using epidermal growth factor receptor (EGFR) antibodies. To better diagnose and assess the prognosis of cancer patients, mutation screening of the BRAFV600E gene should be performed prior to clinical anti-tumor drug therapy to avoid ineffective treatment. METHODS: In our previous study, we developed a real-time wild-type blocking PCR (WTB-PCR), which can amplify the mutant allele at high efficiency while simultaneously inhibiting the amplification of wild-type alleles...

Water splitting is promising for energy storage and conversion, but the sluggish oxygen evolution reaction (OER) hinders its wide application. The search for efficient and low-cost electrocatalysts for oxygen evolution has been pursued owing to their significance for green energy generation and storage. Layered Double Hydroxide (LDH) based materials are promising for the OER to improve this weakness. However, the wide application of LDHs is limited by their electronic properties and active sites. Here we report a simple and promising method to improve the OER catalytic activity via an acid-base reaction, which resulted in an exfoliation process and multiple defects including Co, Fe and O vacancies...

Production of bioenergy and bio-based chemicals by using fermentable sugars released from low-cost renewable lignocellulosic biomass has received great attention. Efficient cellulolytic enzymes are crucial for lignocellulose bioconversion, but high cellulase production cost is limiting the bioconversion efficiency of cellulosic biomass and industrial applications of lignocellulose biorefinery. Studies on induction and regulation of cellulase in filamentous fungi will help to further develop superior fungal strains for efficient cellulase production and reduce cellulase production cost...

Photocatalysis has a potential to become a cost effective industrial process for water cleaning. One of the most studied photocatalysts is titanium dioxide which, as a wide band gap semiconductor, requires ultraviolet (UV) light for its photoactivation. This is at the wavelengths where the efficiency of present-day light emitting diodes (LEDs) decreases rapidly, which presents a challenge in the use of UV-LEDs for commercially viable photocatalysis. There is also a need for accurate photocatalysis measurement of remediation rates of water-borne contaminants for determining optimum exposure doses in industrial applications...

BACKGROUND: The induction of cellulase production by insoluble carbon source cellulose was a common and efficient strategy, but has some drawbacks, such as difficult fermentation operation, substantial cellulase loss, long fermentation time, and high energy-consumption, resulting in high cost of cellulase production in industry. These drawbacks can be overcome if soluble carbon sources are utilized as the inducers for cellulase production. However, until now the induction efficiency of most soluble carbon sources, especially lactose and glucose, is still inferior to cellulose despite extensive efforts have been made by either optimizing the fermentation process or constructing the recombinant strains...

Rice is one of the imperative staple foods, particularly in the developing countries. The exponential boom in human population has resulted in the continuous expansion in the rice industry in order to meet the food demands. The various stages of paddy processing release huge quantity of solid wastes, mainly rice husk, rice husk ash and liquid wastes in the form of rice industry wastewater. The discharge of the rice industry wastewater imparts a substantial threat to the aquatic bodies and the nearby surrounding and, thus, consequently demands eco-benign treatment plan...
