Resource-Based Event Reconstruction of Digital Crime Scenes

To ensure that the potential evidence is readily available in an acceptable form when an incident or a crime occurs, we propose a resource-based event reconstruction prototype that corresponds to different phases of digital forensics framework, and demonstrate its feasibility by assessing the applicability of existing open-source applications to the proposed prototype. The feasibility study results show that the proposed prototype can enhance the capability of an organization for collecting, preserving, protecting, and analysing digital evidence by regarding system resources as an evidence source and system calls as digital events.
Pathwidth, Bandwidth, and Completion Problems to Proper Interval Graphs with Small Cliques

We study two related problems motivated by molecular biology. Given a graph $G$ and a constant $k$, does there exist a supergraph $G'$ of $G$ that is a unit interval graph and has clique size at most $k$? Given a graph $G$ and a proper $k$-coloring $c$ of $G$, does there exist a supergraph $G'$ of $G$ that is properly colored by $c$ and is a unit interval graph? We show that those problems are polynomial for fixed $k$. On the other hand, we prove that the first problem is equivalent to deciding if the bandwidth of $G$ is at most $k-1$. Hence, it is NP-hard and $W[t]$-hard for all $t$. We also show that the second problem is $W[1]$-hard. This implies that for fixed $k$, both of the problems are unlikely to have an $O(n^\alpha)$ algorithm, where $\alpha$ is a constant independent of $k$. A central tool in our study is a new graph-theoretic parameter closely related to pathwidth. An unexpected useful consequence is the equivalence of this parameter to the bandwidth of the graph.
Selective Cell Culture of Primary Breast Carcinoma1

We have used culture conditions which simulate the microenvironment of breast tumors for the isolation and propagation of primary breast tumor cells in vitro. In this monolayer setup, the mixture of cells dissoci ated from primary breast tumors is subjected to self-created gradients of oxygen and nutrients as well as metabolic waste and extracellular pH. The tumor populations isolated under these novel conditions have displayed phenotypic properties characteristic of breast carcinomas, including ho mogeneous expression of cytokeratin 19, and increased mitochondrial retention of the cationic dye rhodamine 123. Nonmalignant cultures from reduction mammoplasty were unable to survive these conditions. One tumor population which reached passage 10 was aneuploid for chromo somes 15 and 17, and displayed a p53 mutation in exon 8. These studies strongly suggest that the culture conditions described here can suppress the growth of normal breast cells, thereby allowing selective isolation of some populations of slow-growing primary tumor cells in vitro.
On the properties of massive Population III stars and metal-free stellar populations

We present realistic models for massive Population III stars and stellar populations based on non-LTE model atmospheres, recent stellar evolution tracks and up-to-date evolutionary synthesis models, to study their spectral properties, including their dependence on age, star formation history, and IMF. (.) The main results regarding integrated stellar populations are: * For young bursts and the case of a constant SFR, nebular continuous emission - neglected in previous studies - dominates the spectrum redward of Lyman-alpha (.). Therefore predicted emission line equivalent widths are considerably smaller than found in earlier studies, whereas the detection of the continuum is eased. Nebular line and continuous emission strongly affect the broad band photometric properties of Pop III objects. * Due to stellar evolution, the hardness of the ionising spectrum decreases rapidly, leading to the disappearance of the characteristic HeII 1640 recombination lines after ~ 3 Myr in instantaneous bursts. * The relative efficiency of ionising photon energy to heavy element rest mass production, eta, of metal-poor and metal-free populations is increased by factors of ~ 4 to 18 with respect to solar metallicity and for ``standard'' IMFs. * The lowest values of eta ~ 1.6 - 2.2 % are obtained for IMFs exclusively populated with high mass stars (M_low >~ 50 Msun). If correct, the yields dominated by pair creation SNae then predict large overabundances of O/C and Si/C compared to solar abundance ratios. Detailed results are given in tabular form and as fit formulae for implementation in other calculations. (abridged abstract)
Accretion Disks in Interacting Binaries: Simulations of the Stream-Disk Impact

We investigate the impact between the gas stream from the inner Lagrangian point and the accretion disk in interacting binaries, using three dimensional Smooth Particle Hydrodynamics simulations. We find that a significant fraction of the stream material can ricochet off the disk edge and overflow towards smaller radii, and that this generates pronounced non-axisymmetric structure in the absorption column towards the central object. We discuss the implications of our results for observations and time-dependent models of low-mass X-ray binaries, cataclysmic variables and supersoft X-ray sources.
A geometric study of Wasserstein spaces: Euclidean spaces

We study the Wasserstein space (with quadratic cost) of Euclidean spaces as an intrinsic metric space. In particular we compute their isometry groups. Surprisingly, in the case of the line, there exists a (unique) ``exotic'' isometric flow. This contrasts with the case of higher-dimensional Euclidean spaces, where all isometries of the Wasserstein space preserve the shape of measures. We also study the curvature and various ranks of these spaces.
The role of supervisors on employees’ voice behavior

PurposeDrawing on social learning theory and social information processing theory, the purpose of this study is to examine how perceived supervisor’s voice behavior relates to employees’ own voice behavior both directly and indirectly through trust in supervisor. In particular, this study also investigates the moderating role of gender in the relationship between trust in supervisor and employee voice behavior. Further, this study proposes that gender moderates the indirect effect of perceived supervisor’s voice behavior on employee voice behavior via trust in supervisor.Design/methodology/approachThe proposed hypothesis was tested by using hierarchical regression analyses and Hayes’ PROCESS macro.FindingsThe results show that perceived supervisor’s voice behavior is positively related to an employee’s own voice behavior and trust in supervisors. In particular, trust in supervisors mediates the relationship between perceived supervisor’s voice behavior and employee’s own voice behavior. Additionally, the relationship between trust in supervisor and employees’ voice behavior was stronger for female employees.Originality/valueThe current study investigates employees’ perception of immediate supervisor’s voice behavior that encourages employees to speak up, thereby providing a more nuanced understanding of the factors that facilitate employee voice behavior. In particular, this study advances the understanding of how and why employees’ perception of supervisors’ voice behavior relates to employees’ voice behavior by examining the mediating and moderating factors.
The Improvement of The Endogenous Antioxidant Property of Stone Fish (Actinopyga lecanora) Tissue Using Enzymatic Proteolysis

The stone fish (Actinopyga lecanora) ethanolic and methanolic tissue extracts were investigated for total phenolic contents (TPCs) as well as antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH•) radical scavenging activity and ferric reducing antioxidant power (FRAP) assays. Both extracts showed low amount of phenolics (20.33 to 17.03 mg of gallic acid equivalents/100 g dried sample) and moderate antioxidant activity (39% to 34% DPPH• radical scavenging activity and 23.95 to 22.30 mmol/100 mL FeSO4 FRAP value). Enzymatic proteolysis was carried out in order to improve the antioxidant activity using six commercially available proteases under their optimum conditions. The results revealed that the highest increase in antioxidant activity up to 85% was obtained for papain-generated proteolysate, followed by alcalase (77%), trypsin (75%), pepsin (68%), bromelain (68%), and flavourzyme (50%) as measured by DPPH• radical scavenging activity, whilst for the FRAP value, the highest increase in the antioxidant activity up to 39.2 mmol/100 mL FeSO4 was obtained for alcalase-generated proteolysate, followed by papain (29.5 mmol/100 mL FeSO4), trypsin (23.2 mmol/100 mL FeSO4), flavourzyme (24.7 mmol/100 mL FeSO4), bromelain (22.9 mmol/100 mL FeSO4), and pepsin (20.8 mmol/100 mL FeSO4). It is obvious that proteolysis of stone fish tissue by proteolytic enzymes can considerably enhance its antioxidant activity.
Detection of virulence genes (bvfA, virB and ure) in Brucella melitensis isolated from aborted fetuses of sheep and goats

Background and Objectives Brucella, causative of brucellosis, has some potential virulence factors involved in Brucella replication and its strategies to circumvent the immune response. One of them is the virB gene that encodes the type IV secretion system proteins (T4SS) involved in intracellular replication of organism. Brucella virulence factor A (bvfA), and urease (ure) has also been described as being implicated in survival, and virulence in the hosts. The aim of this study was to investigate the B. melitensis virulence factor genes among Brucella isolated from aborted fetuses of sheep and goats in Fars province, southern Iran. Materials and Methods A total of 42 isolates of B. melitensis isolated from aborted fetuses between 2005-2011 in Fars province of Iran was used in this study. PCR assay was performed in order to detect the virB, bvfA, and ure genes using specific primers. Results and Conclusions The frequency of bvfA, virB, and ure genes was 78.50%, 73.80%, and 88.09% among all isolates respectively. The results of the present study showed that most Brucella isolates from this region have virulence factors genes (virB, bvfA, ure) in their genome, and most B. melitensis had ure genes that has been hypothesized to play a role in the pathogenesis of disease.

Microscopic dynamics in liquid metals: The experimental point of view

The experimental results relevant for the understanding of the microscopic dynamics in liquid metals are reviewed, with special regard to the ones achieved in the last two decades. Inelastic neutron scattering played a major role since the development of neutron facilities in the 1960s. The last ten years, however, saw the development of third generation radiation sources, which opened the possibility of performing inelastic scattering with x rays, thus disclosing previously unaccessible energy-momentum regions. The purely coherent response of x rays, moreover, combined with the mixed coherent or incoherent response typical of neutron scattering, provides enormous potentialities to disentangle aspects related to the collectivity of motion from the single-particle dynamics. If the last $20\phantom{\rule{0.3em}{0ex}}\text{years}$ saw major experimental developments, on the theoretical side fresh ideas came up to the side of the most traditional and established theories. Beside the raw experimental results therefore models and theoretical approaches are reviewed for the description of microscopic dynamics over different length scales, from the hydrodynamic region down to the single-particle regime, walking the perilous and sometimes uncharted path of the generalized hydrodynamics extension. Approaches peculiar of conductive systems, based on the ionic plasma theory, are also considered, as well as kinetic and mode coupling theory applied to hard-sphere systems, which turn out to mimic with remarkable detail the atomic dynamics of liquid metals. Finally, cutting edge issues and open problems, such as the ultimate origin of the anomalous acoustic dispersion or the relevance of transport properties of a conductive system in ruling the ionic dynamic structure factor, are discussed.
Law and Moral Order: The Influence of Legal Outcomes on Moral Judgment

The current project explores a surprisingly overlooked question regarding the influence of legal outcomes on people’s personal morality. In 4 studies utilizing different scenarios of ethically questionable behavior, we compared the influence of 4 potential legal outcomes: indictment, conviction, exoneration, and closing the case without charges (Studies 1–4); we also examined the influence of these outcomes against the benchmark of people’s default moral positions in the absence of legal information (Studies 3–4), and looked at the role of legitimacy as a potential moderator (Studies 2–3). Results revealed that, as expected, legal outcomes affected people’s personal moral judgments. More specifically, we found that: (a) exoneration and closing the case increased the moral permissibility of the conduct at stake relative to conviction and indictment (Studies 1–4); (b) there was largely no impact of judicial versus nonjudicial outcomes, such that no differences were found between closing the case without charges and exoneration, or between indictment and conviction (Studies 1–3); (c) the impact of the specific legal outcome compared with people’s default moral judgments was dependent on the issue at stake (Studies 3–4); and (d) legitimacy did not moderate the results, such that legal outcomes influenced moral judgment whether or not people held the legal system as legitimate. Taken together, this research suggests that both judicial and nonjudicial legal outcomes play an important role in influencing people’s moral judgments, which has not been previously recognized.
Smart traffic lights switching and traffic density calculation using video processing

Congestion in traffic is a serious problem nowadays. Although it seems to pervade everywhere, mega cities are the ones most affected by it. And it's ever increasing nature makes it imperative to know the road traffic density in real time for better signal control and effective traffic management. There can be different causes of congestion in traffic like insufficient capacity, unrestrained demand, large Red Light delays etc. While insufficient capacity and unrestrained demand are somewhere interrelated, the delay of respective light is hard coded and not dependent on traffic. Therefore the need for simulating and optimizing traffic control to better accommodate this increasing demand arises. In recent years, video monitoring and surveillance systems have been widely used in traffic management for traveler's information, ramp metering and updates in real time. The traffic density estimation and vehicle classification can also be achieved using video monitoring systems. This paper presents the method to use live video feed from the cameras at traffic junctions for real time traffic density calculation using video and image processing. It also focuses on the algorithm for switching the traffic lights according to vehicle density on road, thereby aiming at reducing the traffic congestion on roads which will help lower the number of accidents. In turn it will provide safe transit to people and reduce fuel consumption and waiting time. It will also provide significant data which will help in future road planning and analysis. In further stages multiple traffic lights can be synchronized with each other with an aim of even less traffic congestion and free flow of traffic.
Career Concerns, Monetary Incentives and Job Design

We study optimal incentive contracts when commitments are limited, and agents have multiple tasks and career concerns. The agent's career concerns are determined by the outside market. We show that the principal might want to give the strongest explicit incentives to agents far from retirement to account for the fact that career concerns might induce behavior in conflict with the principal's preferences. Furthermore, we show that maximized welfare might be decreasing in the strength of career concerns, that optimal incentives can be positively correlated with various measures of uncertainty, and that career incentives have strong implications for optimal job design.
Role of Organic Anion-Transporting Polypeptides (OATPs) in Cancer Therapy

The superfamily of organic anion-transporting polypeptides (OATPs, gene symbol SLCO) includes important transporters handling a variety of endogenous and xenobiotic substrates. Currently, 11 human OATPs are known and their substrates include endogenous hormones and their conjugates, anticancer drugs, and imaging agents. The contribution of OATPs to the in vivo disposition of these substrates has been extensively investigated. An accumulating body of evidence also indicates that the expression of some OATPs may be up- or downregulated in several types of cancers, suggesting potential pathogenic roles during the development and progression of cancer. Given that the role of OATPs in handling cancer therapeutics has been already covered by several excellent reviews, this review will focus on the recent progresses on the topic, in particular the role of OATPs in the disposition of anticancer drugs, the impact of OATP genetic variations on the function of OATPs, and the OATPs differentially expressed in cancer and their potential roles in cancer development, progression, and treatment.
Revealing the Strengths and Weaknesses of a Corporate Portal

The role of corporate portal on consolidating an organization's internal and external information and knowledge repositories has been recognized by many organizations worldwide including academic institutions. The deployment of corporate portals has been growing in academia. This qualitative study examined the strengths and weaknesses of a corporate portal deployment at an academic institution based on faculty members' perceptions. The strengths and weaknesses analysis, which is a part of the SWOT (strengths, weaknesses, opportunities and threats) strategic analysis, is very useful to understand an organization’s current position on the deployment of a corporate portal. This study illustrated that the deployment of a corporate portal at an academic institution is relatively successful. The results revealed that the strengths of the corporate portal are mainly related to information quality, system quality and recognized personal benefits; whereas the weaknesses are mainly related to system quality and few are related to information quality and support services quality. Furthermore, this examination provided some insights about success factors of corporate portal.
Factors that influence the use of birth control by Brazilian adolescents

The central objective of this paper is to investigate the antecedents of the use of contraceptive methods by adolescents. For this purpose, we developed and tested a theoretical model that reflects the interrelationships between assessments of self-efficacy of youths and the influences of the partner, socializing agents and adolescents’ goals in life. The results indicate that the intention to use and actual use of contraceptive methods is directly affected by perceptions of self-efficacy, life goals related to stability and education, and the respondent’s sex (boys intend to use birth control methods more than do girls). Also, the attitude of the partner in the relationship and contact with doctors are preponderant factors influencing the intention to use birth control methods. These results are relevant from the theoretical standpoint, by providing a better understanding of adolescents’ behavior, and from a practical perspective, by facilitating the development of marketing strategies and public policies to increase the use of birth control measures among young people.
Computing the roughening transition of Ising and solid-on-solid models by BCSOS model matching

We study the roughening transition of the dual of the two-dimensional (2D) XY model, of the discrete Gaussian model, of the absolute value solid-on-solid model and of the interface in an Ising model on a three-dimensional (3D) simple cubic lattice. The investigation relies on a renormalization group finite size scaling method that was proposed and successfully tested a few years ago. The basic idea is to match the renormalization group flow of the interface observables with that of the exactly solvable body-centred solid-on-solid (BCSOS) model. Our estimates for the critical couplings are , and for the XY model, the discrete Gaussian model and the absolute value solid-on-solid model, respectively. For the inverse roughening temperature of the Ising interface we find . To the best of our knowledge, these are the most precise estimates for these parameters published so far.
Asymptomatic and Symptomatic Carotid Stenosis: An Obsolete Classification?

Since many years, clinical decisions about the management of patients with carotid stenosis have been based on the distinction between “asymptomatic” and “symptomatic” presentations. This was also reflected by the design of previous studies on the surgical versus conservative treatment and of current studies on interventional treatment versus surgery. Both terms, however, only address different phases of activity of the one and the same condition and blur the significant message that carotid stenosis is a most important marker of systemic atherosclerosis, which is accompanied by a much higher risk of cardiovascular events rather than stroke. As a consequence, early diagnosis and followup during best medical treatment, life-style management, regular cardiovascular assessment, and good control of all vascular risk factors should be recommended in all patients with carotid stenosis—whether identified in the long-lasting “silent” or short-lasting “vulnerable” period lasting only a few weeks after cerebral ischemia. Patients in this short time window benefit from additional carotid intervention, under the condition of an individually favorable benefit-risk ratio (“individual vulnerability”).
“Music is my drug”: Alexithymia, empathy, and emotional responding to music

Like alcohol or other drugs, music is often enjoyed by humans for its mood-altering effects. However, there is substantial individual variation in emotional responding to music (ERM). The present study investigated potential roles of trait variables in ERM. Recruitment and testing of 205 adult regular music listeners was accomplished online. They were asked to complete the Geneva Emotional Music Scale (GEMS) retrospectively by rating the felt intensity of 45 music-related emotions based on what they typically experienced when listening to their favorite music. They also completed instruments assessing traits of alexithymia, affect intensity, and empathy, as well as the Big Five factors. Alexithymia, affect intensity, and empathy, but not the Big Five, were moderately positively correlated with ERM as measured by GEMS. In a hierarchical regression, alexithymia and empathy were significant positive predictors of ERM after controlling for the other variables; extraversion was also significant in the final model. The role of empathy as a predictor of ERM was consistent with the emotional contagion interpretation of ERM. The unexpected positive relationship of alexithymia with ERM suggests that alexithymic listeners may rely on music to help them experience emotions more fully. Limitations and potential implications of the findings are discussed.
