A search for the rare decay of a B0 or Bs0 meson into the final state J/ψγ is performed, using data collected by the LHCb experiment in pp collisions at s=7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. The observed number of signal candidates is consistent with a background-only hypothesis. Branching fraction values larger than 1.5×10−6 for the B0→J/ψγ decay mode are excluded at 90% confidence level. For the Bs0→J/ψγ decay mode, branching fraction values larger than 7.3×10−6 are excluded at 90% confidence level; this is the first branching fraction limit for this decay.

We report a study of the suppressed B−→DK−π+π− and favored B−→Dπ−π+π− decays, where the neutral D meson is detected through its decays to the K∓π± and CP -even K+K− and π+π− final states. The measurement is carried out using a proton-proton collision data sample collected by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb−1. We observe the first significant signals in the CP -even final states of the D meson for both the suppressed B−→DK−π+π− and favored B−→Dπ−π+π− modes, as well as in the doubly Cabibbo suppressed D→K+π− final state of the B−→Dπ−π+π− decay. Evidence for the suppressed decay B−→DK−π+π−, with D→K+π−, is also presented. From the observed yields in the B−→DK−π+π−, B−→Dπ−π+π− and their charge conjugate decay modes, the most probable value of the weak phase γ corresponds to γ=(74−19+20)°. This is one of the most precise single-measurement determinations of γ to date.

Chromosomal aberrations and somatic mutations constitute key elements of the pathogenesis of myelodysplastic syndromes (MDS), a clonal hematologic malignancy characterized by cytopenias, a dysplastic bone marrow and propensity to clonal evolution. Next generation sequencing (NGS) enables definition of somatic mutational patterns and clonal architecture as a discovery platform, and for clinical applications. We systematically applied NGS to 707 cases of MDS and MDS-related disorders. 205 cases (low-risk MDS: N=78, high-risk MDS: N=42, MDS/MPN: N=48 and sAML: N=37) were tested by whole exome sequencing (WES). For validation in an additional 502 patients (low-risk MDS: N=192, high-risk MDS: N=104, MDS/MPN: N=111 and sAML: N=95), targeted deep NGS was applied for 60 index genes which were most commonly affected in the cohort analyzed by WES. For NGS data analysis a statistical pipeline was developed to focus on: i) identification of the most relevant somatic mutations, and ii) minimization of false positive results. We studied serial samples from 21 exemplary informative patients. We also compared somatic mutational patterns to those seen in primary AML TCGA cohort (N=201). Given the size of the cohort, there was, for example, a 87% chance of seeing mutations at a frequency of 1% and a 98% of seeing those with a frequency of 2%. While focusing on the most common events, we observed 1117 somatic mutations in 199 genes. The 88 genes mutated mutated in >1% of cases with MDS carried 388 mutations in MDS+sAML (2.5/case), 128 in MDS/MPN (2.7/case) and 398 in pAML (2.0/case). The average number of mutations per case increased during progression (2.2 in lower-risk, 2.8 in higher-risk MDS, 3.4 in sAML). In MDS, the 30 most frequently affected genes were present at least once in 70% of patients. The 30 most frequently mutated genes in MDS/MPN were mutated in 82% of patients. Individual mutations were also sub-grouped according to their function. When we compared three MDS subcate

The need for publishing maps in secure digital format, especially guarantees data integrity which motivated us to propose a scheme that detects and locates modification data with high accuracy while ensuring exact recovery of the original content. In particular, using fragile watermarking algorithm based on reversible manner to embed hidden data in 2D vector map for each spatial features. In this paper, a reversible data-hiding scheme is explored based on the idea of difference expansion with Manhattan distances. A set of invertible integer mappings is defined to extract Manhattan distances from coordinates and the hidden data are embedded by modifying the differences between the adjacent distances. Experiments results show that the proposed scheme has good performance in term invisibility and tamper modification ability. The scheme could detect modification data such addition and deletion some features, and exactly recovery the original content of the 2D vector map.

A quad-tree is a desirable data structure for neighbour search in many applications. Due to the irregular nature of trees, however, there is not an efficient implementation of a quad-tree on GPU. In this paper, we propose and set up CUDA-quad-trees on NVIDIA's GPU+CUDA parallel computing architecture, which takes advantage of the fast on-chip memory of GPU. This data structure for acceleration is used to organize sensor nodes so as to facilitate detection of possible transmitters in simulation of radio propagation in WSNs. Experimental results show that our tree is very efficient and greatly outperforms another CUDA-based tree with one or two order of magnitude speedup in different stages.

We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400 deg2 patch of sky centered on RA 0 h, Dec. −57.5°. The combined maps reach a depth of 57 nK deg in Stokes Q and U in a band centered at 150 GHz. Planck has observed the full sky in polarization at seven frequencies from 30 to 353 GHz, but much less deeply in any given region (1.2 μK deg in Q and U at 143 GHz). We detect 150×353 cross-correlation in B modes at high significance. We fit the single- and cross-frequency power spectra at frequencies ≥150 GHz to a lensed-ΛCDM model that includes dust and a possible contribution from inflationary gravitational waves (as parametrized by the tensor-to-scalar ratio r), using a prior on the frequency spectral behavior of polarized dust emission from previous Planck analysis of other regions of the sky. We find strong evidence for dust and no statistically significant evidence for tensor modes. We probe various model variations and extensions, including adding a synchrotron component in combination with lower frequency data, and find that these make little difference to the r constraint. Finally, we present an alternative analysis which is similar to a map-based cleaning of the dust contribution, and show that this gives similar constraints. The final result is expressed as a likelihood curve for r, and yields an upper limit r0.05<0.12 at 95% confidence. Marginalizing over dust and r, lensing B modes are detected at 7.0σ significance.

The characteristics of decisions and the evaluation of their outcome are highly complex. In this paper, we first give a short analysis of different types of decisions such as long-term and short-term decisions or dilemmas by discussing different scenarios and examples. We identify characteristics of decisions and give a short account of the usually quite complex decision scenarios involved and the high uncertainty of long-term predictions. We introduce serious games as a tool for evaluation of decisions through simulation. By using serious games long-term effects of decisions can be evaluated and known measurement criteria for short-term decision can be transformed to support long-term decisions. © 2012 Springer-Verlag Berlin Heidelberg.

The concept of wisdom has been a term of reflection since the first philosophical definition attempts by Aristotle (384 BC - 322 BC). Different religions and sciences offered possible properties and facets of wisdom - without ever coming to an agreement on how to define the term. As especially cognitive sciences provided new insights during the last decades the time might have come for a revised, more conclusive definition or at least modelization of wisdom, using and integrating the insights of different disciplines out of humanities, cognitive and natural science to create a common base for further interdisciplinary research. Furthermore, we discuss possible measures that are able to cover a least fundamental properties of wisdom including its vague aspects. © 2012 Springer-Verlag Berlin Heidelberg.

It is crucial for educators to understand pitfalls for novice programmers in programming education at computer science course. By giving well-timed advice to students who fall into a pitfall, educators are able to achieve efficient teaching and keep up their students' motivation. However, so far, it is less well-understood how novice students edit source code and why they fall into a pitfall. In this paper, we analyzed coding patterns of novice students empirically. We collected programming activities by students on exercises of programming course, and then performed qualitative and quantitative analysis. In qualitative analysis, experienced programmers analyzed patterns of the novice programmers manually. In quantitative analysis, we focused on transtions of the edit distance between a source code of each student under development and a correct source code in a programming class. As a result, we confirmed coding patterns of novice programmers in case of falling into pitfalls, and the characteristics of transitions of edit distance metric in the case that novice students had faced difficulty in understanding the exercise. © 2012 IEEE.
