ANSWERING INCOMING CALL FOR IMPLICIT AUTHENTICATION USING SMARTPHONE

Smartphones are being used to keep sensitive data and make private transaction other than making calls and receive short messages. Thus, authentication of the smartphones becomes very crucial and important aspect. However, users feel inconvenience and difficult with current authentication methods, from password up to physical biometrics. Implicit authentication system emerged intending to improve the security and convenience of the smartphone users. One of the approaches is considering the way users answer incoming phone calls using their smartphones. We study and evaluate the voice signal from users when answering incoming phone calls. Our study shows that the voice signals capable of authenticating the smartphone users. The experiment conducted shows a very high performance with 98.9% accuracy. These findings will promisingly augment that the novel implicit and transparent authentication system based on voices of answering incoming phone calls is feasible so that authentication of smartphone’s users become easier and unobtrusive.
Genome-Wide Sequence Variation Identification and Floral-Associated Trait Comparisons Based on the Re-sequencing of the ‘Nagafu No. 2’ and ‘Qinguan’ Varieties of Apple (Malus domestica Borkh.)

Apple (Malus domestica Borkh.) is a commercially important fruit worldwide. Detailed information on genomic DNA polymorphisms, which are important for understanding phenotypic traits, is lacking for the apple. We re-sequenced two elite apple varieties, ‘Nagafu No. 2’ and ‘Qinguan,’ which have different characteristics. We identified many genomic variations, including 2,771,129 single nucleotide polymorphisms (SNPs), 82,663 structural variations (SVs), and 1,572,803 insertion/deletions (INDELs) in ‘Nagafu No. 2’ and 2,262,888 SNPs, 63,764 SVs, and 1,294,060 INDELs in ‘Qinguan. ’ The ‘SNP,’ ‘INDEL,’ and ‘SV’ distributions were non-random, with variation-rich or -poor regions throughout the genomes. In ‘Nagafu No. 2’ and ‘Qinguan’ there were 171,520 and 147,090 non-synonymous SNPs spanning 23,111 and 21,400 genes, respectively; 3,963 and 3,196 SVs in 3,431 and 2,815 genes, respectively; and 1,834 and 1,451 INDELs in 1,681 and 1,345 genes, respectively. Genetic linkage maps of 190 flowering genes associated with multiple flowering pathways in ‘Nagafu No. 2,’ ‘Qinguan,’ and ‘Golden Delicious,’ identified complex regulatory mechanisms involved in floral induction, flower bud formation, and flowering characteristics, which might reflect the genetic variation of the flowering genes. Expression profiling of key flowering genes in buds and leaves suggested that the photoperiod and autonomous flowering pathways are major contributors to the different floral-associated traits between ‘Nagafu No. 2’ and ‘Qinguan. ’ The genome variation data provided a foundation for the further exploration of apple diversity and gene–phenotype relationships, and for future research on molecular breeding to improve apple and related species.
Online diagnostics in inverter-fed induction machines using high-frequency signal injection

Fault diagnostics for induction machines using an injected high-frequency carrier signal is presented and analyzed in this paper. Both stator winding fault and broken rotor bar detection is covered. Measurement of the resulting high-frequency negative-sequence current is shown to be capable of detecting both types of faults at their incipient stage. Though sharing similar physical principles to techniques applied to line-connected machines, the use of a high-frequency signal is shown to provide important advantages for inverter-fed machines, such as providing the same performance and drastically reduced sensitivity to the working condition of the machine, i.e., torque and flux levels, and fundamental excitation frequency.
The Repercussions of Childhood Trauma on Posttraumatic Stress: The Mediating Effects of Dissociation and Emotion Dysregulation

The present study explored the mediating effects of dissociation and emotion dysregulation on the relationship between different types of childhood trauma and symptoms of posttraumatic stress. Participants were 181 undergraduate students at Cleveland State University, who competed measures of childhood trauma (emotional abuse, physical abuse, sexual abuse, and general trauma), posttraumatic stress symptoms, dissociation, and emotion dysregulation. Multiple mediation analyses were conducted to examine the model proposed in this study. The results of this study revealed that all trauma types significantly predicted adulthood posttraumatic stress. The relationship between emotional abuse and posttraumatic stress was mediated through both dissociation and emotion dysregulation. Specific indirect effects emerged through dissociation on physical abuse and emotional abuse, and through emotion dysregulation on general trauma, and posttraumatic stress. These findings support prior research that associates posttraumatic stress symptoms to traumatic childhood experiences. Furthermore, the results indicate differential psychopathological outcomes related to type of traumatic experience in early life.
Optimized model checking of multiple properties

This paper addresses the problem of model checking multiple properties on the same circuit/system. Although this is a typical scenario in several industrial verification frameworks, most model checkers currently handle single properties, verifying multiple properties one at a time. Possible correlations and shared sub-problems, that could be considered while checking different properties, are typically ignored, either for the sake of simplicity or for Cone-Of-Influence minimization. In this paper we describe a preliminary effort oriented to exploit possible synergies among distinct verification tasks of several properties on the same circuit. Besides considering given sets of properties, we also show that multiple properties can be automatically extracted from individual properties, thus simplifying difficult model checking tasks. Preliminary experimental results indicate that our approach can lead to significant performance improvements.
An approach for heart disease detection by enhancing training phase of neural network using hybrid algorithm

The disease diagnosis based on artificial intelligence techniques is an effective technique. To enhance the training procedure of the neural network to diagnose the heart disease effectively, we use a hybrid algorithm which is combination of GSO and ABC. Initially, we generate an initial population that has number of members and the members have the weight values which are used to train the neural network. To identify a perfect member to train the neural network, we use the hybrid algorithm operations. We give each member to the neural network and we find the fitness for each member and we categorize the members to perform the hybrid operations i.e. which member has to do which operation. After performing corresponding operations on the categorized members, we get a new set of members and we iterate the process until we get a stable member for producer operation. We choose the weight values of the producer to train the neural network to detect the heart disease.
Analysis, modeling, and applications of coaxial waveguide-based left-handed transmission lines

In this paper, a new realization of left-handed transmission lines (LHTLs) is presented. The proposed structure employs a coaxial waveguide structure to host periodic arrays of split-ring resonators (SRRs) and capacitively loaded strips (CLSs). The SRRs and CLSs are radially mounted on the inner conductor of the coaxial waveguide structure, which provides the necessary polarization for the periodic arrays of SRRs and CLSs to exhibit a negative index of refraction over a specific frequency band. The structure of the proposed coaxial waveguide-based LHTL (CW-LHTL) is optimized by studying the effect of inductive and capacitive couplings on the performance of the structure. The properties of CW-LHTL are studied by analyzing the dispersion diagram and extracting its effective permittivity and permeability. The analysis shows that the proposed CW-LHTL exhibits negative effective permittivity and permeability around the resonant frequency of the SRRs. The inductive and capacitive couplings of the SRRs and CLSs of a CW-LHTL unit cell are related to the periodicity of left-handed material (LHM) in free space. Therefore, the proposed CW-LHTL provides a reliable measurement setup to study the behavior of LHM in free space without the need to use a large number of unit cells. The coaxial waveguide measurement setup is also used to analyze different modified SRRs, which have a smaller size while operating at the same resonant frequency. A coaxial waveguide structure housing a unit cell of the proposed SRR is fabricated and tested. The measurement results show that the proposed modified SRR is up to 46% smaller in size in comparison with the traditional SRR. The applications of CW-LHTL in guided microwave systems are also discussed.
Channel precoder with nonuniform sampling equalizer

A class of channel precoder constructed with equalizer with minimal implementation complexity, and no channel noise amplification effect is proposed in this paper. The derivation on the formulation of the precoder and equalizer pairs are presented. Where the applied equalizer is a simple nonuniform sampling system. Because of the allpass nature of the equalizer, the performance of this class of channel precoder will not be suffered from channel noise amplification effect. The existence of such precoder, equalizer pairs are derived, which is shown to be compatible with that of ordinary linear precoder.
SpatialGraphx: A Distributed Graph Computing Framework for Spatial and Temporal Data at Scale

Development of the Smart City has produced much data with attributions of timestamp and location, but in some applications like investigation of the large bomb explosion in New York, the government takes precedence to investigate the relation data from New York city rather than the whole Country, which prompts us to do some research works in computing partial graph more fast. So we propose SpatialGraphx, a graph parallel computing framework supporting direct and fast partial graph construction and partial graph computation. Leveraging the spatial and temporal attributions of data, SpatialGraphx presents two extensions on the partial graph construction by building a spatio-temporal tree index and on the computation by a new location-based partition strategy. Using mobile network's data with hundred million edges, we demonstrate SpatialGraphx can support direct and fast partial graph construction and enables efficient partial graph analysis for spatial and temporal data. And compared to original Graphx, the improvement of SpatialGraphx is 3x to several orders of magnitude for large enough dataset.
The 2004 Hyperflare from SGR 1806–20: Further Evidence for Global Torsional Vibrations

We report an analysis of archival RXTE data from the 2004 December hyperflare from SGR 1806-20. In addition to the ≈90 Hz QPO first discovered by Israel et al., we report the detection of higher frequency oscillations at ≈150, 625, and 1840 Hz. We also find evidence of oscillations at ≈720, and 2384 Hz, but with lower significances. The 150 Hz QPO has a width (FWHM) of about 17 Hz, an average amplitude (rms) of 6.8% and is associated with the strongest peak in the pulse profile. The 625 Hz oscillation was detected in an average power spectrum from nine successive cycles beginning approximately 180 s after the initial hard spike. It has a width (FWHM) of ≈2 Hz and an average amplitude (rms) during this interval of 8.5%. We find a strong detection of the 625 Hz oscillation in a pair of successive rotation cycles beginning about 230 s after the start of the flare. In these cycles we also detect the 1840 Hz QPO. When the 625 Hz QPO is detected we also confirm the simultaneous presence of 30 and 92 Hz QPOs. The centroid frequency of the 625 Hz QPO detected with RXTE is within 1 Hz of the ≈626 Hz oscillation recently found in RHESSI data by Watts & Strohmayer. We argue that these new findings provide further evidence for a connection of these oscillations with global oscillation modes of neutron stars, in particular, the high-frequency signals may represent toroidal modes with at least one radial node in the crust. We discuss their implications in the context of this model and for the depth of neutron star crusts.
Membranes associated with the disintegration of mycetomal micro-organisms in Sitophilus zea-mais (Mots.) (Coleoptera).

SUMMARY The mycetomal micro-organisms of Sitophilus zea-mais give evidence in electron micrographs of having two peripheral unit membranes, an intermediate layer, intracytoplasmic membranes and DNA-like material. They appear to disintegrate, at times, with the concomitant formation of membrane masses. It is suggested that these are visible with the phasemicroscope and that they are probably myelin figures.
Genome-Wide Copy Number Variations Inferred from SNP Genotyping Arrays Using a Large White and Minzhu Intercross Population

Copy number variations (CNVs) are one of the main contributors to genetic diversity in animals and are broadly distributed in the genomes of swine. Investigating the performance and evolutionary impacts of pig CNVs requires comprehensive knowledge of their structure and function within and between breeds. In the current study, 4 different programs (i.e., GADA, PennCNV, QuantiSNP, and cnvPartition) were used to analyze Porcine SNP60 genotyping data of 585 pigs from one Large White × Minzhu intercross population to detect copy number variant regions (CNVRs). Overlapping CNVRs recalled by at least 2 programs were used to construct a powerful and comprehensive CNVR map, which contained249 CNVRs (i.e., 70 gains, 43 losses, and 136 gains/losses) and covered 26.22% of the regions in the swine genome. Ten CNVRs, representing different predicted statuses, were selected for validation via quantitative real-time PCR (QPCR); 9/10 CNVRs (i.e., 90%) were validated. When being traced back to the F0 generation, 58 events were identified in only Minzhu F0 parents and 2 events were identified in only Large White F0 parents. A series of CNVR function analyses were performed. Some of the CNVRs functions were predicted, and several interesting CNVRs for meat quality traits and hematological parameters were obtained. A comprehensive and lower false rate genome-wide CNV map was constructed for Large White and Minzhu pig genomes in this study. Our results may provide an important basis for determining the relationship between CNVRs and important qualitative and quantitative traits. In addition, it can help to further understand genetic processes in pigs.
Device Studies of Participatory Sensing: Ontological Politics and Design Interventions

This study investigates how ubiquitous sensing technologies are being used to engage the public in environmental monitoring. The academic literature and mainstream media claim participatory sensing is contributing to science, improving the environment and creating new forms of democratic citizenship. Yet there have been few studies that examine its material practices and impacts. This study addresses this gap via three ethnographic ‘device studies’ and an experimental design intervention. The methodology is based on post actor-network theory with a material-semiotic focus on the notion of the ‘device’ (Law & Ruppert 2013), in order to follow the sensing objects over their lifetime from design, usage with participants and later outputs. The design intervention uses the notion of the device as a research method to materially intervene in one of the study sites as a public controversy. The findings show that despite claims in the literature to be an empirical knowledge practice, the subjects and objects of participatory sensing are continually shifting and blurring. Instead, participatory sensing involves a ‘stringing together’ of hardware, participants and rhetorics to form new ontological entities and create publicity. However, this creates conflicts with actors for whom environmental pollution is a health concern, who want to organise collectively and want to engage with decision-making. Yet these studies have shown that it is possible to reconfigure sensing devices with situated ontologies. This led to the building of experimental design prototypes that show that participatory sensing can support pluralistic ontologies and build new connections towards decision-making. The contribution of this study is to identify the ontological politics (Mol 1999) of participatory sensing and demonstrate a ‘device study’ method that combines ethnography with material design to intervene and transform public controversies.
Joint Beamforming and Power Allocation for Secrecy in Peer-to-Peer Relay Networks

This paper investigates the physical-layer security of a multiuser peer-to-peer (MUP2P) relay network for amplify-and-forward (AF) protocol, where a secure user and other unclassified users coexist with a multi-antenna eavesdropper and the eavesdropper can wiretap the confidential information in both two cooperative phases. Our goal is to optimize the transmit power of the source and the beamforming weights of the relays jointly for secrecy rate maximization subject to the minimum signal-to-interference-noise-ratio (SINR) constraint at each user, and the individual and total power constraints. Mathematically, the optimization problem is non-linear and non-convex, which does not facilitate an efficient resource allocation algorithm design. As an alternative, a null space beamforming scheme is adopted at the relays for simplifying the joint optimization and eliminating the confidential information leakage in the second cooperative phase, where the relay beamforming vector lies in the null space of the equivalent channel of the relay to eavesdropper links. Although the null space beamforming scheme simplifies the design of resource allocation algorithm, the considered problem is still non-convex and obtaining the global optimum is very difficult, if not impossible. Employing a sequential parametric convex approximation (SPCA) method, we propose an iterative algorithm to obtain an efficient solution of the non-convex problem. Besides, the proposed joint design algorithm requires a feasible starting point, we also propose a low complexity feasible initial points searching algorithm. Simulations demonstrate the validity of the proposed strategy.
Assessing Process Models with Cognitive Psychology

The importance of a business process model to be understandable to its reader is widely acknowledged. In this vein, several approaches to assess and improve understandability exist, such as theoretical quality frameworks, modeling guidelines and process model metrics. In this paper we propose to investigate the issue of understandability from the angle of cognitive psychology. To this end, we discuss how the cognitive process of inference acts as a central process of problem solving. In particular, we illustrate in how far chunking, computational offloading and external memory might have an impact on the understandability of process models. Our propositions are theory-based so far and will serve as basis for planned empirical investigations, as discussed in the research agenda.

Clubs socio-deportivos en un municipio brasileño: espacio, equipos y contenidos

Sport is an important phenomenon on XXI Century, and sport clubs are a relevant environment for youth sport. Aim: analyze facilities, equipment and contents in social-clubs in Caceres City (Mato Grosso State, Brazil). Method: for collecting data we applied participatory observation, with researcher journal and semi-structured questioners. Results and Discussion: we found the following facilities and equipment: swimming pools (n=8), sport courts (n=4), soccer fields (n=10), fitness rooms (n=1), tennis courts (n=2), sand fields (n=4). The most common activities are related with swimming and soccer, in a sport participation perspective. Only one club had a sport development program, just in soccer. One club has coaches with bachelor degree in Physical Education. Conclusions: clubs offer a good sport structure for systematized sport practice, however, facilities and equipment are underused, and with insufficient qualified coaches.
Relative Proot Auctions

We study independent private value auctions where bidders have preferences over relative payoos. We derive symmetric equilibria for four important auction forms: rst-price, second-price, English, and Dutch. We nd that equilibrium bidding is more aggressive than standard predictions. Indeed, in second-price auctions it is optimal to bid above one's valuation when bidders care about relative payoos. Further, strategic equivalence between second-price and English auctions no longer holds; for all but the two highest-valued bidders, bidding is more aggressive in the second-price auction. Despite the fact that all the auctions we study are ex post eecient, revenue equivalence also no longer holds|English auctions always outperform second-price auctions. Moreover, when two bidders are competing, or when valuations are uniformly distributed, second-price auctions have higher expected revenues than rst-price auctions. Finally, we show that bidding in rst-price relative proot auctions is behaviorally equivalent to bidders having preferences exhibiting constant relative risk aversion.
