Static detection of Android malware by using permissions and API calls

Android smart phones have become more and more popular due to its increasing functionalities, compatibility and convenience. More and more Android applications have been developed and can be downloaded easily from app markets. However, Android malwares have increased significantly in recent years. In this paper, we proposed a feature set containing the permissions and API calls for Android malware static detection. Classifiers that used the proposed feature set outperform those only with the permissions experimentally. It showed that the information of API calls is helpful in recognizing Android malware.
Changes in anthocyanins and polyphenolics during juice processing of Highbush blueberries (Vaccinium corymbosum L.)

: Frozen blueberries (Vaccinium corymbosum L.) were processed into juice and concentrate, and the changes in anthocyanin pigments and polyphenolics (cinnamates, procyanidins, flavonol glycosides) were monitored. While juice yield was 83%, only 32% of the anthocyanins were recovered in single-strength juice. Flavonol, procyanidin and chlorogenic acid recoveries in juice were 35%, 43%, and 53%, respectively. The proportion of polyphenolics remaining in the press-cake residue ranged from 1% (chlorogenic acid) to 18% (anthocyanins). Pronounced losses of anthocyanins and polyphenolics during milling and depectinization are believed to be due to native polyphenol oxidase. Losses during concentration ranged from 1.5% (anthocyanins) to 20% (procyanidins). Striking changes occurred in the anthocyanin profile with malvidin glycosides being most stable and delphinidin glycosides the least.
The role of mental model and shared grounds in human-robot interaction

This paper investigates the role of mental model and shared grounds in human-robot interaction and the relation between them for efficient communication as well as collaboration between human and robot. We tried to conceptualize 3 way relationship among human, robot and world, and to link them in terms of the construction of shared grounds. Based on our conceptual framework of shared grounds, we developed a mediate interface that allows human users to communicate and coordinate with a robot using multimodal icon symbols. A pilot experiment was carried out to examine how people acquire a mental model about 'what' and 'how' a robot can do, and what it knows. The experimental results show that, for the efficient and cooperative human-robot interaction (HRI), a proper linkage between human and robot is required to share perceptual experience, object or procedural knowledge on a task.
Syndecan 4 Regulates FGFR1 Signaling in Endothelial Cells by Directing Macropinocytosis

Macropinocytosis controls the kinetics of endothelial signaling initiated by a fibroblast growth factor receptor. Limiting the Signal Through Macropinocytosis Fibroblast growth factor 2 (FGF2) triggers migration and proliferation of endothelial cells by binding to fibroblast growth factor receptor 1 (FGFR1) and the co-receptor syndecan 4 (S4). Activation of FGFR1 initiates signaling through mitogen-activated protein kinases (MAPKs). Elfenbein et al. found that S4 decreased the internalization of FGFR1 through a process called macropinocytosis. Furthermore, S4-mediated macropinocytosis of FGFR1 decreased the amplitude and increased the deactivation kinetics of MAPK signaling. Thus, these results indicate that S4 controls the duration of MAPK activation in response to binding of FGF2 to FGFR1. Fibroblast growth factor 2 (FGF2) induces endothelial cell migration and angiogenesis through two classes of receptors: receptor tyrosine kinases, such as FGF receptor 1 (FGFR1), and heparan sulfate proteoglycans, such as syndecan 4 (S4). We examined the distinct contributions of FGFR1 and S4 in shaping the endothelial response to FGF2. S4 determined the kinetics and magnitude of FGF2-induced mitogen-activated protein kinase (MAPK) signaling by promoting the macropinocytosis of the FGFR1-S4-FGF2 signaling complex. Internalization of the S4 receptor complex was independent of clathrin and dynamin, proceeded from lipid raft–enriched membranes, and required activation of the guanosine triphosphatases RhoG and Rab5. Genetic knockout of S4, disruption of S4 function, or inhibition of Rab5 led to increased endocytosis and MAPK signaling. These data define the mechanism by which FGFR1 and S4 coordinate downstream signaling upon FGF2 stimulation: FGFR1 initiates MAPK signaling, whereas S4-dependent FGFR1 macropinocytosis modulates the kinetics of MAPK activation. Our studies identify S4 as a regulator of MAPK signaling and address the question of how distinct classes of FGFRs individually contribute to signal transduction in endothelial cells.
Antiretroviral therapies in pregnancy: maternal, fetal and neonatal effects

Background:Therapies containing two reverse transcriptase inhibitors (RTI) with or without protease inhibitors are used with increasing frequency in pregnant HIV-infected women. Objective:To assess the safety of antiretroviral therapy in pregnant women and their newborns. Methods:All clinical events and laboratory abnormalities in pregnant women on RTI with or without protease inhibitors and in their newborns were collected through an observational study. Results:A total of 37 HIV-infected pregnant women have given birth to 30 children (by 30 April 1998). All received RTI, which were combined with protease inhibitors in 16 cases. Twelve women became pregnant while on treatment. Drugs used were as follows: zidovudine (n = 33), lamivudine (n = 33), stavudine (n = 4), indinavir (n = 9), ritonavir (n = 4), nelfinavir (n = 2) and saquinavir (n = 2). Adverse events during pregnancy were anaemia (n = 15), elevation of transaminases (n = 4), nausea/vomiting (n = 4), glucose intolerance (n = 2), nephrolithiasis (n = 2), diarrhoea (n = 2), hypertension (n = 1), insulin-requiring diabetes (n = 1). Adverse events in neonates were prematurity (n = 10), anaemia (n = 8), cutaneous angioma (n = 2), cryptorchidism (n = 2), transient hepatitis (n = 1). Non-life-threatening intracerebral haemorrhage occurred in a premature baby (33 weeks gestation) exposed during fetal life to zidovudine-lamivudine-indinavir, and in a term baby exposed to stavudine-lamivudine-indinavir. Extrahepatic biliary atresia occurred in one newborn exposed to zidovudine-lamivudine-indinavir. Maternal viral load was below 400 copies/ml in 18 out of 30 patients who delivered. One case of mother-to-child HIV transmission was identified. Conclusions:In HIV-infected pregnant women treated with two RTI with or without protease inhibitors, one or more adverse events occurred in 29 out of 37 women and in 14 out of 30 babies. In newborns, frequent prematurity, one case of biliary malformation and one intracerebral haemorrhage in a term baby are of concern. These observations do not preclude combination therapies during pregnancy but emphasize the necessity to maintain updated registers on their safety.
7Ps of Green Marketing as Factors Influencing Willingness to Buy Towards Environmentally Friendly Beauty Products

With society increasingly conscious to the environment, it affected consumers’ decision in choosing a product. For business producers, this phenomenon is seen as opportunities to attract consumers by implementing green values in the marketing process. In this research, the product discuss is environmental friendly beauty product. The 7Ps framework of marketing that has been implemented in The Body Shop Indonesia modified with green values of producers may be a useful tool as consumers’ willingness to buy factors. Each elements of 7Ps green marketing are evaluated based on its importance and effect in willingness to buy for woman consumers in Indonesia. This study aims to determine which attributes of 7Ps green marketing that perceived as important and affect most Indonesian consumers’ willingness to buy for environmentally friendly beauty products (The Body Shop Indonesia) and also the relationship in between. This research is conducted by distributing questionnaires that was addressed to woman age between 19-27 years old and the data was analyzed using frequency and factor analysis, and MANCOVA. Results indicate that attribute in "People" dimension of 7Ps green marketing is considered as the most important and most affecting in consumers’ willingness to buy. It is also found that there is relationship between importance levels of each 7Ps dimension with its degree of influence towards willingness to buy. Furthermore, there is also relationship between consumers’ environmental knowledge with level of importance of each 7Ps green marketing dimension. The findings can be used as suggestion for managers and producers to generate the 7Ps green marketing strategy for their environmental friendly beauty products.

The SAMI Galaxy Survey: Mass as the Driver of the Kinematic Morphology–Density Relation in Clusters

We examine the kinematic morphology of early-type galaxies (ETGs) in eight galaxy clusters in the Sydney-AAO Multi-object Integral-field spectrograph Galaxy Survey. The clusters cover a mass range of and we measure spatially resolved stellar kinematics for 315 member galaxies with stellar masses within 1 R200 of the cluster centers. We calculate the spin parameter, λR, and use this to classify the kinematic morphology of the galaxies as fast or slow rotators (SRs). The total fraction of SRs in the ETG population is FSR = 0.14 ± 0.02 and does not depend on host cluster mass. Across the eight clusters, the fraction of SRs increases with increasing local overdensity. We also find that the slow-rotator fraction increases at small clustercentric radii (Rcl < 0.3 R200), and note that there is also an increase in the slow-rotator fraction at Rcl ∼ 0.6 R200. The SRs at these larger radii reside in the cluster substructure. We find that the strongest increase in the slow-rotator fraction occurs with increasing stellar mass. After accounting for the strong correlation with stellar mass, we find no significant relationship between spin parameter and local overdensity in the cluster environment. We conclude that the primary driver for the kinematic morphology–density relationship in galaxy clusters is the changing distribution of galaxy stellar mass with the local environment. The presence of SRs in the substructure suggests that the cluster kinematic morphology–density relationship is a result of mass segregation of slow-rotating galaxies forming in groups that later merge with clusters and sink to the cluster center via dynamical friction.
An Observer for Three-Phase Current Estimation Using Nonuniform Current Samples

A new approach of reconstructing three-phase currents by fitting sine waves, under the conditions of nonuniform distribution or even nonavailability of samples for substantial portions of a cycle, is proposed. Excessive smoothing by low-pass filters results in loss of accuracy due to damping and instability due to phase lag. A simple zero-order-hold may not be able to fill in large portions of a cycle when data samples are not available. A Luenberger observer, which does not require load-parameter specifications, has been used to estimate the sinusoidal phase currents in the load. The observer is robust and stable under steady and dynamic conditions. The performance of the observer-based, closed-loop current-control scheme has also been compared experimentally with that of a plain trigger-and-hold device
Firm Turnover and Productivity Growth in the Canadian Retail Trade Sector

This paper examines firm turnover and productivity growth in the Canadian retail trade sector. Firm turnover occurs as the competitive process shifts market share from exiting firms and existing firms that contracted to entering firms and existing firms that expanded. There is considerably more firm turnover in the retail sector than in the manufacturing sector and more of it comes from entry and exit. Moreover, contrary to the manufacturing sector where only part of overall productivity growth comes from firm turnover and the re-allocation of resources from the less to the more productive, all of the aggregate productivity growth comes from this source in the retail sector. This suggests that the much-discussed Wal-Mart effect on retail sector productivity mainly comes from the Wal-Mart-created competitive pressure that shifts market share from exitors and declining incumbents to entrants and growing incumbents. Foreign-controlled firms contributed 30% of labour productivity growth and 45% of multifactor productivity growth in the retail trade sector in the period from 1984 to 1996, which are mainly due to the entry of foreign-controlled firms and expansion of more productive foreign-controlled existing firms.
C‐C chemokine receptor 2 (CCR2) deficiency improves bleomycin‐induced pulmonary fibrosis by attenuation of both macrophage infiltration and production of macrophage‐derived matrix metalloproteinases

Macrophage infiltration is implicated in various types of pulmonary fibrosis. One important pathogenetic process associated with pulmonary fibrosis is injury to basement membranes by matrix metalloproteinases (MMPs) that are produced mainly by macrophages. In this study, C‐C chemokine receptor 2‐deficient (CCR2−/−) mice were used to explore the relationship between macrophage infiltration and MMP activity in the pathogenesis of pulmonary fibrosis, using the bleomycin‐induced model of this disease process. CCR2 is the main (if not only) receptor for monocyte chemoattractant protein‐1/C‐C chemokine ligand 2 (MCP‐1/CCL2), which is a critical mediator of macrophage trafficking, and CCR2 −/− mice demonstrate defective macrophage migration. Pulmonary fibrosis was induced in CCR2−/− and wild‐type (CCR2+/+) mice by intratracheal instillation of bleomycin. No significant differences in the total protein concentration in bronchoalveolar lavage (BAL) fluid, or in the degree of histological lung inflammation, were observed in the two groups until day 7. Between days 3 and 21, however, BAL fluid from CCR2−/− mice contained fewer macrophages than BAL fluid from CCR2+/+ mice. Gelatin zymography of BAL fluid and in situ zymography revealed reduced gelatinolytic activity in CCR2−/− mice. Immunocytochemical staining showed weaker expression of MMP‐2 and MMP‐9 in macrophages in BAL fluid from CCR2−/− mice at day 3. Gelatin zymography of protein extracted from alveolar macrophages showed reduced gelatinolytic activity of MMP‐2 and MMP‐9 in CCR2−/− mice. At days 14 and 21, lung remodelling and the hydroxyproline content of lung tissues were significantly reduced in CCR2−/− mice. These results suggest that the CCL2/CCR2 functional pathway is involved in the pathogenesis of bleomycin‐induced pulmonary fibrosis and that CCR2 deficiency may improve the outcome of this disease by regulating macrophage infiltration and macrophage‐derived MMP‐2 and MMP‐9 production.

The Optimal Capital Structure of an Economy

We examine the optimal allocation of equity and debt across banks and industrial firms when both are faced with incentive problems and firms borrow from banks. Increasing bank equity mitigates the bank-level moral hazard but may exacerbate the firm-level moral hazard due to the dilution of firm equity. Competition among banks does not result in a socially efficient level of equity. Imposing capital requirements on banks leads to the socially optimal capital structure of the economy in the sense of maximizing aggregate output. Such capital regulation is second-best and must balance three costs: excessive risk-taking of banks, credit restrictions banks impose on firms with low equity, and credit restrictions due to high loan interest rates.
Endoplasmic and Vascular Surface Activation During Organ Preservation: Refining Upon the Benefits of Machine Perfusion

The endoplasmic reticulum (ER) represents a subcellular target reactive to various cytosolic impairments. The involvement of ER‐stress in organ preservation was investigated, comparing machine preservation, cold storage (CS) and a novel concept of only temporary perfusion after procurement. Rat livers were retrieved 30 min after cardiac arrest and preserved for 18 h by CS, oxygenated machine perfusion for 18 h (18 h MP) or for 2 h with subsequent CS for 16 h (2 h MP + 16 h CS). Upon reperfusion, 18 h MP significantly improved enzyme leakage (ALT, LDH) and promoted a 2‐fold increase of metabolic recovery compared to CS. However, vascular stress, evaluated by endothelin‐release, was significantly elevated after 18 h MP. Interestingly, better viability was obtained using the short‐term perfusion protocol (2 h MP + 16 h CS), which further reduced enzyme leakage, maintained energetic recovery and mitigated endothelin‐release compared to 18 h MP. Caspase 12‐mRNA was upregulated in the 18 h MP‐group but unchanged after CS or 2 h MP + 16 h CS. Activation/cleavage of caspase 12 protein was significantly enhanced after 18 h MP and very low in the 2 h MP + 16 h CS‐group. Correspondingly, electron microscopy showed ultrastructural alterations of ER after CS and especially after 18 h MP but not after 2 h MP + 16 h CS. At this time mitochondrial appearance was unaffected in all groups, suggesting the ER to be an early subcellular target of preservation injury. In our model, ER and vascular endothelium were best protected by only temporary machine perfusion, which also maintained overall graft viability.
Test–Retest Norms and Reliable Change Indices for the MicroCog Battery in a Healthy Community Population Over 50 Years of Age

The increasing availability of computerized test batteries used to assess neuropsychological changes requires the availability of suitable test–retest normative data. Reliable change indices can then be used to evaluate significance of change in an individual's performance on retesting. We tested (N = 40) neurologically normal adults on three occasions (initially, two weeks, and three months) on the MicroCog: Assessment of Cognitive Functioning computerized testing instrument. Normative retest data are presented for two analytic techniques: the Reliable Change Index adjusted for practice and the Standardized Regression-Based technique. At two weeks, the correlation coefficients ranged from . 49 to . 84, with all scores demonstrating significant practice effects. At 3 months, coefficients ranged from . 50 to . 83, with all scores except Attention / Mental Control demonstrating significant practice compared to baseline. Regression equations were generated for all scores using age, sex, education level, and score at Time 1 as predictors. For all measures the only significant predictor was the Time 1 score. The reliable change indices and regression equations presented here can be used to determine the significance of change from predicted retest scores in a matched interventional cohort.
Neuroprotection of glial cell line‐derived neurotrophic factor in damaged spinal cords following contusive injury

Glial cell line‐derived neurotrophic factor (GDNF) acts as a potent survival factor for many neuronal populations, including spinal motoneurons, indicating the therapeutic promise of GDNF for neurological disorders. Injury to spinal cord (SCI) triggers processes destructive to ascending sensory and descending motor conduction and extends tissue loss, thereby leading to permanent behavioral dysfunction. In this study, we attempted to examine whether GDNF protects neurons from SCI and subsequently lessens locomotor deficit in SCI rats. We utilized the NYU weight‐drop device developed at New York University to induce spinal cord contusion at the T9–10 spinal segment. After SCI, GDNF was administrated into the cord 1–2 mm rostral and caudal to the epicenter. Animals receiving GDNF treatment showed significant improvement over phosphate‐buffered saline (PBS)‐treated controls on the Basso Beattie Bresnahan (BBB) locomotor rating scale (P < 0.01‐0.001). GDNF treatment increased the remaining neuronal fibers with calcitonin gene‐related peptide, neurofilament, and growth‐associated protein 43 immunoreactivity in injured spinal tissues compared with PBS‐treated controls. Moreover, treatment with GDNF caused approximately 50% cell survival in the contused spinal cord tissues. Examination of signal transduction triggered by GDNF indicated that GDNF injection transiently induced activation of the mitogen‐activated protein (MAP) kinase pathway in the spinal cord. Additionally, an up‐regulation of anti‐apoptotic Bcl‐2 levels in the contusive center of the damaged spinal cord was observed 24 hr post‐GDNF injection. Together our results show that GDNF exerts behavioral and anatomic neuroprotection following SCI. Additionally, GDNF‐activated MAP kinase and Bcl‐2 signaling may contribute to neuronal survival after spinal cord contusion. © 2002 Wiley‐Liss, Inc.
Moderating effects of performance measurement use on the relationship between organizational performance, measurement diversity and product innovation

This study sets'out to address the question of whether the effect of organizational' performance measurement diversity on product innovation will differ depending on how organizational performance measures are used. There is strong empirical evidence that many companies who are successful today are less likely to be successful in the future because they fail to innovate. It is surprisingly then, that when everyone stresses the importance of innovation, there are many organizations adopting performance measurement systems, which may constrain their innovativeness. Currently, there are three differing perspectives on the effect of measurement on a firm's propensity to innovate. Moreover, each of these has empirical evidence to support its argument. The first perspective views measurement as constraining innovation because it impedes creativity, experimentation, and search in firms. The second perspective views measurement as helping innovation because it triggers search, facilitates decision-making, and increases risk-taking. The third perspective views measurement as having insignificant or little impact on innovation because it is used primarily for signalling. A possible explanation of the contradiction in the empirical findings of these studies is that they generally ignore how measurement is used. Therefore, using the behavioural theory of innovation, I argue that one possible way of resolving the contradictory findings is by incorporating measurement use as a moderating variable. Using data from a cross-sectional, large-scale, probability sample survey of 145 UK manufacturing firms, I show that organizational performance measurement diversity interacts with performance measurement use to determine product innovation. My findings suggest that the extent to which a firm offers new products will be more positively (negatively) associated with performance
