Deep4MalDroid: A Deep Learning Framework for Android Malware Detection Based on Linux Kernel System Call Graphs
Venue: 2016 IEEE/WIC/ACM International Conference on Web Intelligence Workshops (WIW)

With explosive growth of Android malware and due to its damage to smart phone users (e.g. stealing user credentials, resource abuse) Android malware detection is one of the cyber security topics that are of great interests. Currently, the most significant line of defense against Android malware is anti malware software products, such as Norton, Lookout, and Comodo Mobile Security, which mainly use the signature based method to recognize threats. However, malware attackers increasingly employ techniques such as repackaging and obfuscation to bypass signatures and defeat attempts to analyze their inner mechanisms. The increasing sophistication of Android malware calls for new defensive techniques that are harder to evade, and are capable of protecting users against novel threats. In this paper, we propose a novel dynamic analysis method named Component Traversal that can automatically execute the code routines of each given Android application (app) as completely as possible. Based on the extracted Linux kernel system calls, we further construct the weighted directed graphs and then apply a deep learning framework resting on the graph based features for newly unknown Android malware detection. A comprehensive experimental study on a real sample collection from Comodo Cloud Security Center is performed to compare various malware detection approaches. Promising experimental results demonstrate that our proposed method outperforms other alternative Android malware detection techniques. Our developed system Deep4MalDroid has also been integrated into a commercial Android anti malware software.
The retinoid X receptor from mud crab: new insights into its roles in ovarian development and related signaling pathway
Venue: Scientific reports

In arthropods, retinoid X receptor (RXR) is a highly conserved nuclear hormone receptor. By forming a heterodimeric complex with the ecdysone receptor (EcR) RXR is known to be vital importance for various physiological processes. However, in comparison to EcR, the RXR signaling pathway and its roles in crustacean reproduction are poorly understood. In the present study, the RXR mRNA was detected in the ovarian follicular cells of mud crab Scylla paramamosain (SpRXR) and during ovarian maturation, its expression level was found to increase significantly. In vitro experiment showed that both SpRXR and vitellogenin (SpVg) mRNA in the ovarian explants were significantly induced by 20 hydroxyecdysone (20E) but not methyl farnesoate (MF) However, differing from the in vitro experiment, injection of MF in in vivo experiment significantly stimulated the expressions of SpRXR and SpVg in female crabs at early vitellogenic stage, but the ecdysone and insect juvenile hormone (JH) signaling pathway genes were not induced. The results together suggest that both MF and SpRXR play significant roles in regulating the expression of SpVg and ovarian development of S. paramamosain through their own specific signaling pathway rather than sharing with the ecdysone or the insect JH.
A retrospective study of the prevalence of anaemia in pregnancy at booking in Niger Delta, Nigeria
Venue: Journal of obstetrics and gynaecology the journal of the Institute of Obstetrics and Gynaecology

We reviewed the records of antenatal clinic attendees over a period of 9 years to determine the prevalence of anaemia at booking. The laboratory records of 8751 out of a total of 37,506 pregnant women who booked for antenatal care between 2004 and 2013 at the BMSH were reviewed. The effects of maternal age, educational status, parity, gestational age, haemoglobin genotype and infections on the prevalence of anaemia were investigated. The prevalence of anaemia at booking was 69.6% most of whom had moderate anaemia. Anaemia was significantly prevalent in the 10 19 year age group, and in women with secondary education, in their 2nd trimester and with SS genotype. Anaemia also increased with gestational age, this however was not statistically significant. There was no statistical difference between those who are human immunodeficiency virus (HIV) positive and had anaemia and those who are HIV negative who also had anaemia. This study shows that anaemia in pregnant women is still unacceptably high considering the consequences and despite interventions on the ground to reduce prevalence. There is a need to review the intervention measures with emphasis on programmes that would increase awareness among pregnant women and the general public.
A Research Agenda for Online Linguistic Surveillance of Threatening Messages
Venue: J. Digit. Forensics Secur. Law

Threats are by definition a communicative act, and as such, it becomes an essential obligation of the field of communication to ascertain what they communicate, and when they communicate imminent credible risk. This paper proposes a research and theory based set of over 20 potential linguistic risk indicators through which corpora of actual online threat messages may discriminate credible from non credible threats. Some of these are obviously easier to code automatically than others, but all can be rated, and used as potential construct validation criteria. Rating scales are proposed, existing threat corpora are identified, and some prospective computational linguistic procedures are identified. Implications for ongoing threat surveillance and its applications are explored.
Expanding the Regulatory Network for Meristem Size in Plants.
Venue: Trends in genetics TIG

The remarkable plasticity of post embryonic plant development is due to groups of stem cell containing structures called meristems. In the shoot, meristems continuously produce organs such as leaves, flowers, and stems. Nearly two decades ago the WUSCHEL/CLAVATA (WUS/CLV) negative feedback loop was established as being essential for regulating the size of shoot meristems by maintaining a delicate balance between stem cell proliferation and cell recruitment for the differentiation of lateral primordia. Recent research in various model species (Arabidopsis, tomato, maize, and rice) has led to discoveries of additional components that further refine and improve the current model of meristem regulation, adding new complexity to a vital network for plant growth and productivity.
Assessment of carotid plaque neovascularization by contrast enhanced ultrasound and high sensitivity C reactive protein test in patients with acute cerebral infarction: a comparative study
Venue: Neurological Sciences

Vulnerable carotid plaque easily ruptures and causes cerebral infarction. Plaque inflammation and neovascularization have both been shown as important characteristics in vulnerable plaque. We assessed neovascularization within carotid plaque using contrast enhanced ultrasound, and also assessed inflammation, using high sensitivity C reactive protein (hs CRP) testing, in acute cerebral infarction patients. A total of 106 patients with acute cerebral infarction and 40 controls were enrolled in the study. All subjects had been previously found to have carotid atherosclerotic plaques, and the plaques were classified as soft plaque, hard plaque, mixed plaque, and calcified plaque, using carotid artery ultrasound. Contrast enhanced ultrasound was performed on the plaques for quantitative analysis and hs CRP levels were measured. The results showed that plaque enhancement was present in 81.1 of cerebral infarction patients and 40.0 of controls. The contrast parameters for cerebral infarction patients were significantly different from controls. For cerebral infarction patients, soft plaque showed the highest enhanced percentage, 95.1 with contrast parameters significantly different to other types of plaque. The hs CRP levels of enhanced cerebral infarction patients were higher than in non enhanced patients. Correlation analysis in cerebral infarction patients showed that hs CRP levels were closely related to the contrast parameters. Acute cerebral infarction patients showed intense contrast enhancement and inflammation in carotid plaque, and different types of plaque had various degrees of enhancement, suggesting that contrast enhanced ultrasound and hs CRP might be used for plaque risk stratification.
A novel head gesture based interface for hands free control of a robot
Venue: 2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)

Within this work a novel head gesture based interface for hands free control of a collaborative robot is developed and evaluated. Based on previous work, robot control is divided into several control groups for intuitive head motion based control. The switching commands to select and switch between these robot control groups are given by four gestures performed with head movements. The head movements were measured using a nine axis inertial measurement unit. The control of a robot with the novel interface was evaluated objectively as well as subjectively. The objective evaluation contains the measurement of time needed for the given control task and the number of trials for switching between the different groups of robot control. The subjective evaluation was carried out with a questionnaire. All subjects were able to perform the given task of controlling a robot arm with the head gesture based interface.
Interventions to increase or decrease the length of primary care physicians' consultation.
Venue: The Cochrane database of systematic reviews

Observational studies have shown differences in process and outcome between the consultations of primary care physicians whose average consultation lengths differ. These differences may be due to self selection. This is the first update of the original review.  To assess the effects of interventions to alter the length of primary care physicians' consultations.  We searched the following electronic databases until 4 January 2016: the Cochrane Central Register of Controlled Trials (CENTRAL) MEDLINE, EMBASE, ClinicalTrials.gov, and World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) SELECTION CRITERIA Randomised controlled trials and non randomised controlled trials of interventions to alter the length of primary care physicians' consultations.  Two review authors independently extracted data and assessed the risk of bias of included studies using agreed criteria and resolved disagreements by discussion. We attempted to contact authors of primary studies with missing data. Given the heterogeneity of studies, we did not conduct a meta analysis. We assessed the certainty of the evidence for the most important outcomes using the GRADE approach and have presented the results in a narrative summary.  Five studies met the inclusion criteria. All were conducted in the UK, and tested short term changes in the consultation time allocated to each patient. Overall, our confidence in the results was very low; most studies had a high risk of bias, particularly due to non random allocation of participants and the absence of data on participants' characteristics and small sample sizes. We are uncertain whether altering appointment length increases primary care consultation length, number of referrals and investigations, prescriptions, or patient satisfaction based on very low certainty evidence. None of the studies reported on the effects of altering the length of consultation on resources used.  We did not find sufficient evidence to support or refute a policy of altering the lengths of primary care physicians' consultations. It is possible that these findings may change if high quality trials are reported in the future. Further trials are needed that focus on health outcomes and cost effectiveness.
The Impact of Oil Price Shocks on the U.S. Stock Market: A Note on the Roles of U.S. And Non U.S. Oil Production

Kilian and Park (2009) find shocks to oil supply are relatively unimportant to understanding changes in U.S. stock returns. We examine the impact of both U.S. and non U.S. oil supply shocks on U.S. stock returns in light of the unprecedented expansion in U.S. oil production since 2009. Our results underscore the importance of the disaggregation of world oil supply and of the recent extraordinary surge in the U.S. oil production for analysing impact on U.S. stock prices. A positive U.S. oil supply shock has a positive impact on U.S. real stock returns. Oil demand and supply shocks are of comparable importance in explaining U.S. real stock returns when supply shocks from U.S. and non U.S. oil production are identified.
The impact of oil price shocks on the volatility of the Turkish stock market

The objective of this paper is to examine the impact of oil price shocks on the volatility of Istanbul Stock Exchange National 100 index (ISE 100) ISE sector indices including ISE financial (ISE FIN) ISE industrial (ISE IND) and ISE Service (ISE SRV) applying EGARCH model of Nelson (1991) for the period spanning from January 1988 to April 2012. Our empirical analysis considers the volatility shifts due to the structural breaks in modelling volatility so that the modified version of the ICSS algorithm of Inclan and Tiao (1994) is used to detect possible volatility shifts. EGARCH model is conducted across both full sample and sub samples. The results reveal that the parameter estimates of variance equation in EGARCH models change across samples. This suggests that variance breaks are empirically a relevant feature of ISE and sector indices in a developing country, Turkey. ISE 100 and sector indices have unique characteristics and the characteristics have to be taken into account.
Desensitization of Axial Compressor Performance and Stability to Tip Clearance size

This paper presents a computational and analytical study to identify and elucidate fundamental flow features associated with the desensitization of performance and aerodynamic stability of an axial compressor rotor to tip clearance change. Parametric studies of various design changes to a baseline double circular arc airfoil axial rotor led to the identification of two flow features associated with reducing sensitivity to tip clearance, namely, high incoming meridional momentum in the tip region and reduction/elimination of double tip leakage. Numerical experiments were subsequently performed on the baseline rotor geometry to validate these two flow features and explain the associated flow physics by variations in incoming meridional momentum and pitch size. Finally, two designs were proposed, namely, a full forward chordwise sweep (FFCS) rotor and a rotor with gradual stagger angle reduction in the outer span, to exploit these flow features. The results indicated that both designs produce the intended flow effects and exhibit lower sensitivity of performance and aerodynamic stability to tip clearance.
Perceived Benefit and Risk as Multidimensional Determinants of Bitcoin Use: A Quantitative Exploratory Study
Venue: ICIS

Over recent years, the innovative decentralized payment system Bitcoin has received much attention in practice and academia. Despite a growth of transaction volume and an increasing attention in the area of e commerce, there is little academic research examining the factors influencing adoption. To fill this research gap, this paper documents an exploratory study of the key determinants and inhibitors of Bitcoin use. Drawing upon the Technology Acceptance Model and a literature review, we integrate various benefits and risks of Bitcoin use to form the multidimensional constructs Perceived Benefit and Perceived Risk. We propose and empirically test a theoretical model that explains the use of Bitcoin as an online payment system for legitimate purchases and money transfers. Furthermore, we recognize several conceptual and methodological development potentialities for technology acceptance theories in the context of decentralized and sharing economy systems.
Spray coated silver nanowires as transparent electrodes in OPVs for Building Integrated Photovoltaics applications

The application of spray coated silver nanowires (AgNWs) onto OPVs for building Integrated Photovoltaics (BIPVs) is demonstrated. By using AgNWs with PEDOT:PSS, a transparent conductive layer was demonstrated on top of an P3HT:PCBM active layer with a sheet resistance of 30 O/ for 90% transparency. This has been applied to two separate configurations; semi transparent OPVs for solar glazing applications and OPVs onto an opaque substrate, namely steel. For the latter, a novel technique to planarise the steel substrate with an intermediate layer is also presented, with a substantial decrease in surface roughness reported to ensure that the substrate is smooth enough to use for OPV fabrication. The use of SU 8 as an intermediate layer reduced the surface roughness to RA=10 nm, which is one of the lowest values reported to date, and was achieved on a low cost substrate (DC01 low carbon steel) using solution processing.
Do Social Workers Apply "Love Thy Neighbor as Thyself" to Gay, Lesbian, Bisexual, and Transpersons in the South?
Venue: Journal of homosexuality

States there has been a spate of legislative bills and initiatives that blatantly stigmatize and discriminate against the lesbian, gay, bisexual, and transgender (LGBT) community. This study was a cross sectional, exploratory survey designed to measure the attitudes, perceptions, and behaviors of Tennessee social workers and future social workers toward the LGBT population and toward proposed discriminatory legislation. A 3 way factorial ANOVA investigated the effects of political affiliation, religious affiliation, and social contact on the dependent measures. Significant main effects were found. Self reported political affiliation was found to be the most important factor predicting LGBT acceptance and LGBT respect among this sample.

The essential elements to growth fostering relationships, mutual empathy and authenticity, are able to flourish at the Women's Empowerment Forum. The planning, implementation and evaluation method successfully used by one group of women is offered.
The Big Rig: Trucking and the Decline of the American Dream

Ocejo's Masters of Craft and Viscelli's The Big Rig both illustrate how working class jobs in today's economy ain't what they used to be. Viscelli explores how truck driving is no longer 'one of the best blue collar jobs in the US' (p. 9) while Ocejo focuses on 'how middle class kids' take 'working class jobs' made trendy through a sense of handcrafted authenticity (p. 129) Both books illuminate how perceptions of the work, particularly independent contracting and hip craft trades, obscure the unstable realities of jobs in these industries. Offering sociological analysis of the economic context in which these occupations are changing, both books highlight how good working class jobs are increasingly scarce and available to only a privileged few.
Removal of reactive dyes from wastewater assisted with kaolin clay by magnesium hydroxide coagulation process

Application of magnesium hydroxide as a coagulant for treating reactive dyes wastewater assisted with kaolin was studied. The coagulation performance and floc properties were investigated under different dosages and initial turbidity. The relationship between Flocculation Index (FI) and reactive dyes removal was then discussed with controlled experiments using intelligent Particle Dispersion Analyzer (iPDA) Kaolin clay had significantly influence on floc formation and reactive dyes removal. The suitable magnesium ion dose of 144 mg/L was obtained under initial turbidity of 45 NTU and pH value of 12. The results showed that final turbidity decreased with increasing coagulant dose. Reactive dyes removal efficiency tended to increase with the increase of initial turbidity of kaolin. The experiments showed that the higher FI value of the system, the higher reactive dyes removal efficiency was obtained. Floc image showed that average floc size of reactive red (X 3B) is smaller than that of reactive yellow (X R) Based on the changes of zeta potential and floc properties, charge neutralization and precipitate enmeshment were proposed to the main coagulation mechanisms.
Giant Piezoelectricity and High Curie Temperature in Nanostructured Alkali Niobate Lead Free Piezoceramics through Phase Coexistence.
Venue: Journal of the American Chemical Society

Because of growing environmental concerns, the development of lead free piezoelectric materials with enhanced properties has become of great interest. Here, we report a giant piezoelectric coefficient (d33) of 550 pC/N and a high Curie temperature (TC) of 237 degC in (1 x y)K1 wNawNb1 zSbzO3 xBiFeO3 yBi0.5Na0.5ZrO3 (KNwNSz xBF yBNZ) ceramics by optimizing x, y, z, and w. Atomic resolution polarization mapping by Z contrast imaging reveals the intimate coexistence of rhombohedral (R) and tetragonal (T) phases inside nanodomains, that is, a structural origin for the R T phase boundary in the present KNN system. Hence, the physical origin of high piezoelectric performance can be attributed to a nearly vanishing polarization anisotropy and thus low domain wall energy, facilitating easy polarization rotation between different states under an external field.
Answering Pattern Queries Using Views
Venue: IEEE Transactions on Knowledge and Data Engineering

Answering queries using views has proven effective for querying relational and semistructured data. This paper investigates this issue for graph pattern queries based on graph simulation. We propose a notion of pattern containment to characterize graph pattern matching using graph pattern views. We show that a pattern query can be answered using a set of views if and only if it is contained in the views. Based on this characterization, we develop efficient algorithms to answer graph pattern queries. We also study problems for determining (minimal, minimum) containment of pattern queries. We establish their complexity (from cubic time to NP complete) and provide efficient checking algorithms (approximation when the problem is intractable) In addition, when a pattern query is not contained in the views, we study maximally contained rewriting to find approximate answers; we show that it is in cubic time to compute such rewriting, and present a rewriting algorithm. We experimentally verify that these methods are able to efficiently answer pattern queries on large real world graphs.
Approximating Graph Pattern Queries Using Views
Venue: CIKM

This paper studies approximation of graph pattern queries using views. Given a pattern query Q and a set V of views, we propose to find a pair of queries Qu and Ql, referred to as the upper and lower approximations of Q w.r.t. V, such that (a) for any data graph G, answers to (part of) Q in G are contained in Qu(G) and contain Ql(G) and (b) both Qu and Ql can be answered by using views in V. We consider pattern queries based on both graph simulation and subgraph isomorphism. We study fundamental problems about approximation using views. Given Q and V, (1) we study whether there exist upper and lower approximations of Q w.r.t. V. (2) How to find approximations that are closest to Q w.r.t. V if exist? (3) How to answer upper and lower approximations using views in V? We give characterizations of the problems, study their complexity and approximation hardness, and develop algorithms with provable bounds. Using real life datasets, we verify the effectiveness and efficiency of approximating simulation and subgraph queries using views.
