description: Summary: Recent advances in sequencing technologies have revolutionized genetic studies. Although high-coverage sequencing can uncover most variants present in the sequenced sample, low-coverage sequencing is appealing for its cost effectiveness. Here, we present AbCD (arbitrary coverage design) to aid the design of sequencing-based studies. AbCD is a user-friendly interface providing pre-estimated effective sample sizes, specific to each minor allele frequency category, for designs with arbitrary coverage (0.5–30×) and sample size (20–10 000), and for four major ethnic groups (Europeans, Africans, Asians and African Americans). In addition, we also present two software tools: ShotGun and DesignPlanner, which were used to generate the estimates behind AbCD. ShotGun is a flexible short-read simulator for arbitrary user-specified read length and average depth, allowing cycle-specific sequencing error rates and realistic read depth distributions. DesignPlanner is a full pipeline that uses ShotGun to generate sequence data and performs initial SNP discovery, uses our previously presented linkage disequilibrium-aware method to call genotypes, and, finally, provides minor allele frequency-specific effective sample sizes. ShotGun plus DesignPlanner can accommodate effective sample size estimate for any combination of high-depth and low-depth data (for example, whole-genome low-depth plus exonic high-depth) or combination of sequence and genotype data [for example, whole-exome sequencing plus genotyping from existing Genomewide Association Study (GWAS)].
从国际法视角看巴勒斯坦的国家身份 / A Review of The Statehood of Palestine from The Perspective of International Law

description: 巴勒斯坦人民的自决权得到包括国际法院的咨询意见在内的国际法支持。落实“两国方案”、建立一个独立自主的巴勒斯坦国，是巴勒斯坦人民行使外部自决权的现实选择；争取加入联合国、国际刑事法院等国际组织或机构，进而追究以色列对巴勒斯坦人民犯下的战争罪责任，是巴勒斯坦人民多年追求实现的梦想。国际刑事法院检察官的意见表明，巴勒斯坦人民虽长期遭受以色列的暴行，却无法追究以色列的国家责任、实现其权利救济，其原因在很大程度上是由于巴勒斯坦国家身份的缺失!近年来，巴勒斯坦成功地加入联合国教科文组织、成为联合国的非会员观察员国；巴勒斯坦批准多项国际条约、加入国际刑事法院并向国际刑事法院起诉以色列，是其追求国家身份的历史征程上的重大进展。 According to the United Nations’ partition plan of Israel-Palestine, Palestinians enjoy autonomy. But with Israel’s invasion by force, thousands of Palestinian people have been displaced and made homeless. In its Advisory Opinion, “the legitimacy of the building of an isolation wall in the occupied Palestinian territories”, the ICJ confirmed that the Palestinians enjoy the people’s right to self-determination. Also, a tit-for-tat legal struggle was launched in the UNSC and the GA, the UNESCO, the ICC and other agencies concerning the issue of Palestinian’s national identity. In September 2011, Palestine applied to become a formal member state in the UN, and failed to get the Security Council’s support due to the US and Israel’s blockade. Shortly thereafter, Palestine was allowed to join the UNESCO. On November 29, 2012, Palestine upgraded its status to “Non-Member Observer” through the GA’s votes. The focus of Palestine’s national identity is on whether Palestine obtains the desired qualification of the United Nations Member States.

Bulk Duals for Generic Static, Scale-Invariant Holographic CFT States

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Near horizon geometries have been widely studied, and have found many applications. Certain static, near horizon geometries are now understood to be bulk duals to CFTs with static scale-invariant sources under the AdS/CFT correspondence. However, static near-horizon geometries aren't just scale-invariant, they have extra `enhanced' symmetry. This means that they can only be the bulk duals for a special class of static, scale-invariant sources that share this enhanced symmetry. The purpose of this paper is to consider bulk duals for more generic static, scale-invariant sources, without this extra symmetry. These solutions are quite different to near-horizon geometries. In place of the extremal horizon they have a null singularity. We find specific examples of such bulk geometries numerically for the cases of pure gravity, and for an abelian gauge field.

description: Motivation: RNA-seq techniques provide an unparalleled means for exploring a transcriptome with deep coverage and base pair level resolution. Various analysis tools have been developed to align and assemble RNA-seq data, such as the widely used TopHat/Cufflinks pipeline. A common observation is that a sizable fraction of the fragments/reads align to multiple locations of the genome. These multiple alignments pose substantial challenges to existing RNA-seq analysis tools. Inappropriate treatment may result in reporting spurious expressed genes (false positives) and missing the real expressed genes (false negatives). Such errors impact the subsequent analysis, such as differential expression analysis. In our study, we observe that ∼3.5% of transcripts reported by TopHat/Cufflinks pipeline correspond to annotated nonfunctional pseudogenes. Moreover, ∼10.0% of reported transcripts are not annotated in the Ensembl database. These genes could be either novel expressed genes or false discoveries.Results: We examine the underlying genomic features that lead to multiple alignments and investigate how they generate systematic errors in RNA-seq analysis. We develop a general tool, GeneScissors, which exploits machine learning techniques guided by biological knowledge to detect and correct spurious transcriptome inference by existing RNA-seq analysis methods. In our simulated study, GeneScissors can predict spurious transcriptome calls owing to misalignment with an accuracy close to 90%. It provides substantial improvement over the widely used TopHat/Cufflinks or MapSplice/Cufflinks pipelines in both precision and F-measurement. On real data, GeneScissors reports 53.6% less pseudogenes and 0.97% more expressed and annotated transcripts, when compared with the TopHat/Cufflinks pipeline. In addition, among the 10.0% unannotated transcripts reported by TopHat/Cufflinks, GeneScissors finds that >16.3% of them are false positives.Availability: The software can be downloaded at http://csbio.unc.edu/genescissors/Contact: weiwang@cs.ucla.eduSupplementary information: Supplementary data are available at Bioinformatics online.

description: We have employed HQET to give the spin-parity quantum numbers for recently observed bottom strange states $B_{sJ}(6063)$ and $B_{sJ}(6114)$ by LHCb collaborations. By exploring flavour independent parameters $ Δ_{F}^{(c)} =Δ_{F}^{(b)}$ and $ λ_{F}^{(c)} = λ_{F}^{(b)}$, we calculated masses of experimentally missing bottom strange meson states $2S, 1P, 1D$. We have also analyzed these bottom strange masses by taking ${1/m_Q}$ corrections which lead modifications of parameter terms as $ Δ_{F}^{(b)} =Δ_{F}^{(c)} + δΔ_F$ and $ λ_{F}^{(b)} = λ_{F}^{(c)}δλ_F$. Further, we have analyzed their two-body decays, couplings, and branching ratios via the emission of light pseudoscalar mesons. Based on predicted masses and decay widths, we tentatively identified the states $B_{sJ}(6063)$ as $2^3S_1$ and $B_{sJ}(6114)$ as $1^3D_1$. Our predictions provide crucial information for future experimental studies.

description: Conversational recommendation systems (CRS) aim to timely and proactively acquire user dynamic preferred attributes through conversations for item recommendation. In each turn of CRS, there naturally have two decision-making processes with different roles that influence each other: 1) director, which is to select the follow-up option (i.e., ask or recommend) that is more effective for reducing the action space and acquiring user preferences; and 2) actor, which is to accordingly choose primitive actions (i.e., asked attribute or recommended item) that satisfy user preferences and give feedback to estimate the effectiveness of the director's option. However, existing methods heavily rely on a unified decision-making module or heuristic rules, while neglecting to distinguish the roles of different decision procedures, as well as the mutual influences between them. To address this, we propose a novel Director-Actor Hierarchical Conversational Recommender (DAHCR), where the director selects the most effective option, followed by the actor accordingly choosing primitive actions that satisfy user preferences. Specifically, we develop a dynamic hypergraph to model user preferences and introduce an intrinsic motivation to train from weak supervision over the director. Finally, to alleviate the bad effect of model bias on the mutual influence between the director and actor, we model the director's option by sampling from a categorical distribution. Extensive experiments demonstrate that DAHCR outperforms state-of-the-art methods.

description: The ability to raise funds is a skill that most modern project managers need. While a good deal of literature exists on the strategies NGOs employ to raise funds for their operations, less attention has been paid to the strategies used by students involved in Project-Based Learning courses that often partner with NGOs. Fundraising is an important skill that not only provides students with opportunities for creativity, but also helps them develop the communication skills they will need in the work they do after they graduate.In this paper, we discuss the fundraising strategies developed by MBA students in 204 social projects completed between 2002 and 2014. The projects were done in partnership with 39 community partners in Sao Paulo, Brazil (NGOs and Public Institutions). In our study, we followed quantitative and qualitative research methods, analyzing data and documents from the projects’ databases. We identified six different fundraising strategies: organizing raffles, soliciting donations from private corporations, organizing paying events, utilizing online social networks developing crowdfunding, and soliciting individual donations.

description: We examine the relation between oxygen abundances in the narrow-line regions (NLRs) of active galactic nuclei (AGNs) estimated from the optical emission lines through the strong-line method (the theoretical calibration of Storchi-Bergmann et al.(1998)), via the direct Te-method, and the central intersect abundances in the host galaxies determined from the radial abundance gradients. We found that the Te-method underestimates the oxygen abundances by up to ~2 dex (with average value of ~0.8 dex) compared to the abundances derived through the strong-line method. This confirms the existence of the so-called "temperature problem" in AGNs. We also found that the abundances in the centres of galaxies obtained from their spectra trough the strong-line method are close to or slightly lower than the central intersect abundances estimated from the radial abundance gradient both in AGNs and Star-forming galaxies. The oxygen abundance of the NLR is usually lower than the maximum attainable abundance in galaxies (~2 times the solar value). This suggests that there is no extraordinary chemical enrichment of the NLRs of AGNs.

description: Belaga Formation is the most widespread and a better- known formation of Rajang Group (covering up to 95%) in the lower Rajang area (central Sarawak). The thick deep marine sediments of Rajang Group represent a major submarine fan and/or to some extent an accretionary prism (Hutchison, 1996; Moss, 1998) and is one of the world’s largest ancient submarine fans. The Belaga Formation is believed to reach great thickness between 4.5 km and 7.5 km (Hutchison, 2005), excluding the repetitive sequences through folding and thrusting. It was subdivided into five members mostly based on palaeontological distinctions along with little sedimentological variations. These members are (in ascending order) Layar, Kapit, Pelagus, Metah and Bawang, younging northwards away from the Lupar Line (Liechti et al., 1960; Wolfenden, 1960). The Layar member is the oldest unit of the Belaga Formation but is the least studied with respective to detailed turbidite facies analysis and sedimentology. The main objective of this research is to develop a depositional model for the Layar member based on comprehensive investigations of recent road‐cut exposures around Betong, Saratok and Roban areas, Sarawak, Malaysia (Figure 1).

description: This paper presents a new approach for optimising the design of tidal stream turbine farms. In this approach, the turbine farm is represented by a turbine density function that specifies the number of turbines per unit area and an associated continuous locally-enhanced bottom friction field. The farm design question is formulated as a mathematical optimisation problem constrained by the shallow water equations and solved with efficient, gradient-based optimisation methods. The resulting method is accurate, computationally efficient, allows complex installation constraints, and supports different goal quantities such as to maximise power or profit. The outputs of the optimisation are the optimal number of turbines, their location within the farm, the overall farm profit, the farm's power extraction, and the installation cost. We demonstrate the capabilities of the method on a validated numerical model of the Pentland Firth, Scotland. We optimise the design of four tidal farms simultaneously, as well as individually, and study how farms in close proximity may impact upon one another.

description: Summary: Although the 1000 Genomes haplotypes are the most commonly used reference panel for imputation, medical sequencing projects are generating large alternate sets of sequenced samples. Imputation in African Americans using 3384 haplotypes from the Exome Sequencing Project, compared with 2184 haplotypes from 1000 Genomes Project, increased effective sample size by 8.3–11.4% for coding variants with minor allele frequency <1%. No loss of imputation quality was observed using a panel built from phenotypic extremes. We recommend using haplotypes from Exome Sequencing Project alone or concatenation of the two panels over quality score-based post-imputation selection or IMPUTE2’s two-panel combination.
Performance of the Seven-step Procedure in Problem-based Hospitality Management Education

Year: 2016

description: The study focuses on the seven-step procedure (SSP) in problem-based learning (PBL). The way students apply the seven-step procedure will help us understand how students work in a problem-based learning curriculum. So far, little is known about how students rate the performance and importance of the different steps, the amount of time they spend on each step and the perceived quality of execution of the procedure. A survey was administered to a sample of 101 students enrolled in a problem-based hospitality management program. Results show that students consider step 6 (Collect additional information outside the group) to be most important. The highest performance-rating is for step two (Define the problem) and the lowest for step four (Draw a systemic inventory of explanations from step three). Step seven is classified as low in performance and high in importance implicating urgent attention. The average amount of time spent on the seven steps is 133 minutes with the largest part of the time spent on self-study outside the group (42 minutes). The assessment of the execution of a set of specific guidelines (the Blue Card) did not completely match with the overall performance ratings for the seven steps. The SSP could be improved by reducing the number of steps and incorporating more attention to group dynamics.

description: We compare the performance of mass estimators for elliptical galaxies that rely on the directly observable surface brightness and velocity dispersion profiles, without invoking computationally expensive detailed modeling. These methods recover the mass at a specific radius where the mass estimate is expected to be least sensitive to the anisotropy of stellar orbits. One method (Wolf et al. 2010) uses the total luminosity-weighted velocity dispersion and evaluates the mass at a 3D half-light radius $r_{1/2}$, i.e., it depends on the GLOBAL galaxy properties. Another approach (Churazov et al. 2010) estimates the mass from the velocity dispersion at a radius $R_2$ where the surface brightness declines as $R^{-2}$, i.e., it depends on the LOCAL properties. We evaluate the accuracy of the two methods for analytical models, simulated galaxies and real elliptical galaxies that have already been modeled by the Schwarzschild's orbit-superposition technique. Both estimators recover an almost unbiased circular speed estimate with a modest RMS scatter ($\lesssim 10 \%$). Tests on analytical models and simulated galaxies indicate that the local estimator has a smaller RMS scatter than the global one. We show by examination of simulated galaxies that the projected velocity dispersion at $R_2$ could serve as a good proxy for the virial galaxy mass. For simulated galaxies the total halo mass scales with $σ_p(R_2)$ as $M_{vir} \left[M_{\odot}h^{-1}\right] \approx 6\cdot 10^{12} \left( \frac{σ_p(R_2)}{200\, \rm km\, s^{-1}} \right)^{4}$ with RMS scatter $\approx 40 \%$.

The two main results in this paper are this decomposition encodes the numeric data of the Jordan canonical form of the matrix. We also describe how the eigenscheme can be interpreted as the zero locus of a global section of the tangent bundle on projective space. This interpretation allows one to see eigenvectors and generalized eigenvectors of matrices from an alternative viewpoint.

description: Motivation: It has been known for more than 2 decades that after RNA polymerase II (RNAPII) initiates transcription, it can enter into a paused or stalled state immediately downstream of the transcription start site before productive elongation. Recent advances in high-throughput genomic technologies facilitated the discovery that RNAPII pausing at promoters is a widespread physiologically regulated phenomenon. The molecular underpinnings of pausing are incompletely understood. The CCCTC-factor (CTCF) is a ubiquitous nuclear factor that has diverse regulatory functions, including a recently discovered role in promoting RNAPII pausing at splice sites.

description: Photoresponse of bimetallic Au-Ag nanoparticle embedded soda glass (Au-Ag@SG) substrate is reported for surface plasmon assisted optical switching using 808 nm excitation. Au-Ag@SG system is made by an ion beam technique where Ag^+ is introduced first in the soda glass matrix by ion exchange technique. Subsequently 400 keV Au^+ is implanted in the sample for different fluences which is followed by an ion beam annealing process using 1 MeV Si^+ at a fixed fluence of 2E16 ions.cm^{-2}. Characteristic surface plasmon resonance (SPR) peaks around 400 and 550 nm provided evidence for the presence of Au and Ag nanoparticles. An optical switching in the Au-Ag@SG system with 808 nm, which is away from the characteristic SPR peaks of Ag and Au nanoparticles, suggests the possible role of TPA owing to the presence of interacting electric dipole in these systems. The role of surface plasmon polariton is emphasized for the propagation of electronic carrier belonging to the conduction electron of Au-Ag system in understanding the observed photoresponse. Unique excitation dependent photoresponse measurements confirm the possible role of TPA process. A competitive interband and intraband transitions in the bimetallic system of Au and Ag with may be primarily responsible for the observation, which are validated qualitatively using finite difference time domain calculations where inter-particle separation of Au and Ag play an important role. Thus, a smart way of optical switching can be envisaged in noble bimetallic nanocluster system where long wavelength with higher skin depth can be used for communication purpose.

description: This paper describes the implementation of problem-based learning (PBL) principles in an undergraduate IT service management course, followed by the results about student satisfaction and work performance. The results indicate the students’ general satisfaction with the course implementation, as well as some challenges regarding the self-assessment and peer assessment of their work. The findings also reveal the students’ better work performance in project results than in traditional knowledge tests, which reinforces the indications about their positive attitudes towards the interactive PBL environment. The cluster analyses identified seven different patterns in student behaviour regarding course performance. The presented results can be considered a new aspect of the development and amendment of the information and communication technology (ICT) skills requested by future employers. In this regard, the demand for innovation in the education of future ICT professionals arises from the need for experts equipped with both IT and business skills.

description: Optimal signaling for secrecy rate maximization in Gaussian MIMO wiretap channels is considered. While this channel has attracted a significant attention recently and a number of results have been obtained, including the proof of the optimality of Gaussian signalling, an optimal transmit covariance matrix is known for some special cases only and the general case remains an open problem. An iterative custom-made algorithm to find a globally-optimal transmit covariance matrix in the general case is developed in this paper, with guaranteed convergence to a \textit{global} optimum. While the original optimization problem is not convex and hence difficult to solve, its minimax reformulation can be solved via the convex optimization tools, which is exploited here. The proposed algorithm is based on the barrier method extended to deal with a minimax problem at hand. Its convergence to a global optimum is proved for the general case (degraded or not) and a bound for the optimality gap is given for each step of the barrier method. The performance of the algorithm is demonstrated via numerical examples. In particular, 20 to 40 Newton steps are already sufficient to solve the sufficient optimality conditions with very high precision (up to the machine precision level), even for large systems. Even fewer steps are required if the secrecy capacity is the only quantity of interest. The algorithm can be significantly simplified for the degraded channel case and can also be adopted to include the per-antenna power constraints (instead or in addition to the total power constraint). It also solves the dual problem of minimizing the total power subject to the secrecy rate constraint.

description: Motivation: Scientists and regulators are often faced with complex decisions, where use of scarce resources must be prioritized using collections of diverse information. The Toxicological Prioritization Index (ToxPi™) was developed to enable integration of multiple sources of evidence on exposure and/or safety, transformed into transparent visual rankings to facilitate decision making. The rankings and associated graphical profiles can be used to prioritize resources in various decision contexts, such as testing chemical toxicity or assessing similarity of predicted compound bioactivity profiles. The amount and types of information available to decision makers are increasing exponentially, while the complex decisions must rely on specialized domain knowledge across multiple criteria of varying importance. Thus, the ToxPi bridges a gap, combining rigorous aggregation of evidence with ease of communication to stakeholders.

description: The genus Leptospermum (Myrtaceae) is widespread in Australia and contains several species that are of increasing interest to produce bioactive honey. Here, we used the Maxent algorithm to investigate bioclimatic, climatic, and soil variables as predictors for potential distributions of seven Leptospermum species that have been identified as useful for bioactive honey production in Australia (L. lanigerum, L. liversidgei, L. nitens, L. polygalifolium, L. scoparium, L. speciosum, and L. whitei). Bioclimatic and climatic variables, mainly those related to moist conditions, were the best predictors for the distribution of the species. Leptospermum lanigerum and L. scoparium were suitable species in areas in southwestern Australia and Tasmania, while L. polygalifolium was suitable for eastern Australia. For L. nitens, appropriate areas were found only in western and southern regions, whereas only border ranges in Queensland and New South Wales were considered suitable for L. liversidgei, L. speciosum, and L. whitei. Notably, the latter areas were identified as a potential ‘hotspot’ for Leptospermum species. Our study can assist the incipient Leptospermum honey industry in Australia in identifying suitable local species and the local maintenance requirements for the species chosen.

description: A Brønsted acid-catalyzed reaction of 6-amino uracil and isatin-derived propargylic alcohols for the synthesis of a series of oxindole-fused pyrimidine in good-to-high yields was achieved (up to 94%). Furthermore, the reaction of isatin-derived propargylic alcohols and 1,3-dimethylbarbituric acid or ethyl 3-aminocrotonate gave oxindoles containing furopyrimidine or pyrrole, respectively, in moderate-to-good yields under relatively mild reaction conditions.

description: Burr grinding is one of the post-weld improvement methods that are widely used in various industries to improve the fatigue strength of welds: bridges, offshore structures, ships and land-based structures. In this paper, main influencing parameters and effect of burr grinding technique on the fatigue strength for butt-welded, longitudinal welded, doubling plates, load-carrying transverse, non-load carrying transverse welded and T-joints as well as I-section with cope hole and out-of-plane longitudinal welds has been evaluated, based on the extracted 395 fatigue data points from 34 existing publications. The specimens used in these studies with yield strength 175 MPa < σYS <1100 MPa, which were tested with stress ratio -1 < R < 0.5, are analyzed and assessed with statistical methods. The assumed value of S-N slope m = 4 and proposed FAT classes seem to be applicable for the extracted data. More experimental testing is needed to draw the conclusion more exactly.

description: Summary: Many algorithms analyze enhancers for overrepresentation of known and novel motifs, with the goal of identifying binding sites for direct regulators of gene expression. Twine is a Java GUI with multiple graphical representations (‘Views’) of enhancer alignments that displays motifs, as IUPAC consensus sequences or position frequency matrices, in the context of phylogenetic conservation to facilitate cis-regulatory element discovery. Thresholds of phylogenetic conservation and motif stringency can be altered dynamically to facilitate detailed analysis of enhancer architecture. Views can be exported to vector graphics programs to generate high-quality figures for publication. Twine can be extended via Java plugins to manipulate alignments and analyze sequences.

description: Using polymeric nanocomposites incorporated Pd to promote C‐C coupling reactions has been found as one of the most successful strategies. In this paper we apply graphene oxide (GO) as an efficient surface immobilized by water‐soluble poly (ethylene glycol)‐imidazole followed by introduction of PdCl2 salt to obtain the desired catalyst. Catalytic performance of this composite was investigated in the Suzuki–Miyaura cross‐coupling reaction under mild reaction conditions and superior results were obtained. The hydrophilic nature of the catalyst and well distribution of Pd lead to superior catalytic activity in water media. Moreover, the Suzuki–Miyaura reaction proceed successfully with excellent yield and short reaction time without any loss of activity even after seven consecutive reaction cycles.
