Geometric evolutions driven by threshold dynamics

whereS(·) is a continuous function taking values in the space S of n × n symmetric matrices andv is real-valued. Special cases of (1.2) are motion by curvature, corresponding to S(n) ≡ I andv(n) ≡ 0, and curvature independent motions, corresponding to S(n) ≡ 0. Solutions of these geometric evolution problems typically develop singularities, regardless of the smoothness of the initial data (see [12], [14]). To overcome such difficulties, the level set approach was introduced by Chen, Giga, and Goto [8] and independently by Evans and Spruck [10]. In [10] motion by mean curvature is dealt with while in [8] more general geometric motions are discussed. Their ideas are based on considering interfaces as level sets of the solution of a degenerate parabolic partial differential equation. One approach to (1.1) is that some classes of dynamics which model the microscopic behavior of physical phenomena (for example, threshold dynamics, cellular automata) provide approximate schemes for (1.1). Among others, Bence, Merriman, and Osher [6] first proposed a simple approximation scheme (BMO) for motion by mean curvature. Later, Evans [9] and Barles and Georgelin [2] gave the first analysis of the BMO algorithm. More recently, Ishii, Pires,
Changes in Sediment Characteristics upon Oyster Reef Restoration, NE Florida, USA

As ecosystem engineers, oysters alter a host of physical and chemical characteristics of their environment. Oyster reef construction (or restoration) can therefore be expected to have wide ranging effects, from increased refuge for organisms, to lower turbidity. We measured changes in sediment characteristics and benthic nutrient fluxes near a constructed intertidal oyster reef in the Guana Tolomato Matanzas National Estuarine Research Reserve in NE Florida, USA. Within one year of reef construction, particle size distribution shifted towards finer sediment, and organic matter content increased to 7.3% ± 2.1 (standard error) compared to 2.9% ± 0.8 (standard error) at control sites, where oysters were absent. After three years, up to 15 cm of this fine, organic-rich sediment had accreted immediately shoreward of the reef. In benthic flux experiments performed under dark conditions, reef sediments released 167 μM/m2/hr NH4+ compared to –4 μM/m2/hr from control site sediments. Under light conditions both reef and control fluxes were insignificant. This was presumably due to uptake by benthic microalgae; chlorophyll a concentrations were 3 times higher in reef sediments compared to controls. Deposition of organic rich sediment near oyster reefs might render important ecosystem services from carbon burial and perhaps increased denitrification. However, burial of live oysters with excessive sediment accretion might threaten reef success in some cases. Our results highlight the complexity of physical-biological interactions and the need for complete assessment of ecosystem services in order to optimize design and thoroughly evaluate restoration outcomes.
Fingerprinting Android Obfuscation Tools Using Visualization

Android has become one of the most popular mobile device operating system. Indeed, its security issues have attracted a lot of attention. One of the major security concern is use of obfuscation strategies to evade anti-malware solutions. Android malware authors are increasingly using code obfuscation tools and techniques to hide malicious code. In this work, we introduce a new method to fingerprint the obfuscators used in Android apps by virtue of visualization analysis. First, binary files contained in Android apps are visualized into images. Then two types of statistical features are calculated upon those images. Those features are analyzed and synthesized into effective information to fingerprint the obfuscators used. The results show that our visualization-based method is able to reveal the information about the obfuscators used in the Android application development.
New variables for classical and quantum gravity in all dimensions: III. Quantum theory

We quantize the new connection formulation of (D + 1)-dimensional general relativity developed in our companion papers by loop quantum gravity (LQG) methods. It turns out that all the tools prepared for LQG straightforwardly generalize to the new connection formulation in higher dimensions. The only new challenge is the simplicity constraint. While its ‘diagonal’ components acting at edges of spin-network functions are easily solved, its ‘off-diagonal’ components acting at vertices are non-trivial and require a more elaborate treatment.
FAKTOR-FAKTOR RISIKO RISIKO DALAM PERUSAHAAN JASA PENGIRIMAN

In this era of globalization, can not be denied that the delivery of goods is needed, either by individuals or by organizations / companies. Delivery of goods (raw materials, semi-finished materials, or finished goods) that are not timely can cause inhibition of the production process. Package delivery service is a business services meripan goods that are very much the competition, therefore the income of goods services companies especially package goods packages tend to fluctuate decline as experienced by one of the domestic delivery services. With so many business competition for goods merchandise services, competition in the future will increase or change faster so that the demand map of these services will also change, if the service company does not follow the change impossible the company will exist. That is why management is required for the risks that often arise in the delivery of goods. Risk management steps that can be done include the management of human resources business competition freight services, delivery errors, goods damage sent, theft or fire warehouse. By knowing the various risks typically faced by the company, then handling the risks quickly and accurately can minimize the risks faced by the company, so spend large funds.
Trs 20 , Trs 23 , Trs 31 and Bet 5 participate in autophagy through GTPase Ypt 1 in Saccharomyces cerevisiae

TRAPP (transport protein particle) is a large, highly conserved, multi-subunit complex. Four types of TRAPP complexes (I, II, III and most recently IV) have been identified in Saccharomyces cerevisiae. Studies on the roles of TRAPP II, TRAPP III and TRAPP IV specific subunits (Trs130, Trs85 and Trs33) have demonstrated that TRAPP II, TRAPP III and TRAPP IV activate the small GTPases that regulate autophagy. Up to now, the roles of the common TRAPP subunits have been well studied in vesicle transport. However, the roles of the common TRAPP subunits and their relationship to Ypt/Rab GTPases in autophagy are not clear. In this paper, we examined Trs20, Trs23, Trs31, and Bet5 (the common TRAPP subunits), which are required for starvation-induced autophagy and the cytoplasm-to-vacuole targeting (Cvt) pathway. During autophagy, GFP-Atg8 accumulates as single or multiple dots and is not recruited into the pre-autophagosomal structures (PAS) in trs20ts, trs23ts, trs31ts and bet5ts mutant cells. Furthermore, these dots are linked to the endoplasmic reticulum in mutant cells. Additionally, overexpression of Ypt1, but not Ypt31, suppresses the autophagy defect in trs20ts, trs23ts, trs31ts and bet5ts mutant cells. Based on these results, we concluded that Trs20, Trs23, Trs31, and Bet5 are required for autophagy, and that these common TRAPP subunits regulate autophagy partially through GTPase Ypt1, but not Ypt31.
Impact of workplace spirituality on job satisfaction: Mediating effect of trust

Abstract Workplace spirituality is a renowned topic now-a-days and is gaining gratitude and value among academicians and industrial people. Workplace spirituality (WPS) aims at meaningful work, sense of community, and value of organization. The purpose of the present study is to examine the relationship between workplace spirituality dimensions and work satisfaction by taking trust as a mediator. Using convenience sampling, a five-point Likert scale questionnaire is used to get data from teachers working in the education sector. Two hundred questionnaires were rotated in universities and 174 responses were generated. Multiple regression is used to test the hypotheses of the study using Barron and Kenny’s method. The results showed that WPS has a significantly positive relationship with trust and trust significantly mediates the impact of workplace spirituality on job satisfaction. In future, new dimensions should be added to workplace spirituality. New moderators should be checked along with the mediator. Creativity in the form of improved communication among the teachers can be generated with the help of the promotion of workplace spirituality. The findings indicated that there is a positive relationship between WPS and job satisfaction and trust between employees would mediate the interaction of WPS and job satisfaction as the p-values are less than . 05.
Urban Structure and Energy—A Review

The nature and form of the urban environment is a critical determinant of the sustainability of our society, as it is responsible directly for a large proportion of consumed energy, and influences indirectly the patterns and modes of energy consumed in everyday activities. We examine the current state of research into the energy and greenhouse gas emissions attributable directly or indirectly to urban form. Specifically, we look at the embodied (construction) and operational energy attributable to the construction, maintenance and use of residential dwellings, and we review the literature on the relationship between urban structure and private travel behaviour. While there is clear evidence from both intra- and inter-city comparisons that higher density, transit-oriented cities have lower per-capita transport energy use, the effect of housing density on residential (in-house) energy use is less clear. More detailed research is needed to examine the relationships between urban form and overall energy use.
Contaminating Factors in University Students ’ Evaluation of Instructors

The present study seeks to determine the variables explaining differences between the scores of student ratings given to instructors within the context of the university through discriminant analysis. Ratings given by students were grouped into two groups based on their means and instructors were labeled as low-rated and high-rated. Predictors identified by discriminant analysis are (i) class size, (ii) credit, (iii) grade level, (iv) mean grade, and (v) number of sections. Results of the study suggested that low rated instructors are those who teach courses with smaller number of students, lower credits, higher grade levels, higher mean grades, and one section. Identification of source of differences between ratings may provide invaluable information for those who are interested in assessment of instructional effectiveness.
Effect of Currency Fluctuations on the Economic Growth Potential of Nigeria

The exchange rate is one of the most important determinants of a country's relative level of economic health. This study examines the effect of currency fluctuations on the economic growth potential of Nigeria using the World Bank Development Indicators data from 1970-2012. The study through the Augmented Dickey Fuller (ADF)/ unit root test found that the variables used in the model are integrated of the order one while export and interest rate are integrated of the order zero. Using the Johansen co integration tests shows the presence of long run relationship between variables. The Error Correction Model (ECM) results suggest that exchange rate has a negative significant impact on GDP in the short run and long run. The study therefore recommends that the competitiveness and stability of the exchange rate should be given due consideration as this will increase economic growth through increased investment. Keywords: Exchange rate, Economic growth, ADF, ECM, Nigeria
Evaluation of Bioactivity and Preliminary Phytochemical Investigation of Herbal Plants Against Ampicillin Resistant Bacteria

Presently, natural products are extensively used as substitute of synthetic drugs because of natural and environment friendly antimicrobial actions due to presence of bioactive compounds. These bioactive compounds are found extensively in herbs. In this study, bioactivity and phytochemical study of crude extracts of Ocimum basilicum, Thymus vulgaris, Rosmarinus officinalis and Origanum vulgare against ampicillin resistant bacterial strains isolated from fruits and vegetables eaten as raw, was investigated. Bacterial strains were isolated from the surface of selected washed fruits and vegetables by serial dilution method. Three morphologically different strains (A, P and L) were selected on the basis of resistance to ampicillin (150ug/ml). 16s rRNA sequencing revealed that bacterial strains A, P and L belong to Pseudomonas aeruginosa strain A, Pseudomonas aeruginosa strain P and Rhodobacter sphaeroides , respectively. Phytochemical screening showed presence of different chemical compounds such as alkaloids, tannins, saponins, phlobotannins, quinones, coumarin and flavonoids. Occurrence of saponins and flavonoids in the extract was further confirmed by thin layer chromatography (TLC). Ocimum basilicum, Rosmarinus officinalis and Origanum vulgare extracts caused inhibition of the isolated ampicillin resistant organisms ( Pseudomonas aeruginosa ) but effect of Thymus vulgaris was more pronounced. Anti-mitotic study revealed the ability of these extracts to reduce dividing cells by the anti-mitotic properties and this is helpful in inhibition of the development of cancer cells. Therefore, these plants can be used to discover natural products that will aid in more effective developments of new drug research activities.
Assessment of the Impact of Productive Safety Net Program in Kindo Didaye Woreda, Wolaita Zone, Southern Nations Nationalities and Peoples’ Regional State, Ethiopia

Poverty and food insecurity go together in many circumstances. Chronic food insecurity is one of the main problems which have been affecting millions of Ethiopians. Productive Safety-Net Program (PSNP), is one of the main food security Programs, has been undertaking by the government of Ethiopia with the aim of fulfilling food gap and promoting asset accumulation to food insecure households. However, studies indicate that the success of PSNP in achieving its aim is an area of debate. The study was to assess and explore the impact of PSNP on economic changes of the beneficiaries by looking at changes of the probability of food gap months, asset accumulation and SLM practices in Kindo Didaye Woreda, Wolayta zone, SNNPRS. The research used random sampling technique to collect cross sectional data from 97 PSNP and 89 non-PSNP participants. It was analyzed by both descriptive and econometrics methods. In econometric analysis propensity scores matching technique was applied to estimate the impacts of PSNP on asset accumulation and Sustainable Land Management (SLM) practices. The study revealed that the mean number of months that a household cover its food requirements for PSNP participants was 2.63 whereas for non-PSNP participants was 1.82 months. This implies that PSNP has contributed to decline food gap more for PSNP participants than non-PSNP participants. It showed that PSNP Participant has positive impact on livestock holding (0.63 TLU) and SLM (soil bund (13 m/ha) and stone bund construction (14 m/ha) and chemical fertilizer use (10.9 Kg/ha)) and showed an adverse effect on the value of non-livestock assets holding as likely due to expense of beneficiaries’ transfer on consumption. Almost all PSNP can be considered as narrowing food gap and promoting asset accumulation and SLM practices over time. Despite the long-term requirement of sustainable livelihood improvement, it is understandable that PSNP is possible instrument for practitioners and policy makers to reach the poor. Therefore, to sustain food security in the study area considerable effort should be made to cover the remaining food gap and create awareness on asset accumulation together with further work on environmental impact of the program.

IoT and Cloud-Based Energy Monitoring and Simulation Platform

Nowadays, in order to optimize resource consumption and reduce costs, companies concern themselves with the adoption of innovative energy efficiency solutions. Substantiating the decision to implement energy efficiency measures is challenging, due to a high number of factors that influence the rentability of the project, such as weather conditions, energy pricing, laws and regulations, available resources and energy demand. Thus, each company faces a unique combination of factors that needs to be properly evaluated prior to the adoption of energy efficiency measures. The paper presents an IoT and Cloud-based energy monitoring and simulation platform that aims to help companies monitor energy production and consumption within various cost-centers, forecast the energy production potential and simulate the economic efficiency for multiple investment scenarios.
Value Management: A Systematic Approach for Improving Time Performance in Construction Projects

The construction industry is considered to be the largest contributor to the nation's economy. However, there are many challenges that had to be overcome to ensure construction projects are successful in achieving the minimum cost to utilize the necessary resources in the success of the project. Some of the construction projects failed to be completed on schedule due to the negligence of certain parties in ensuring that the project value is at the maximum level. Responding to the challenge, this research hopes to counter this problem and help towards the betterment of the construction industry using a value management approach. Therefore, this paper discusses the successful factors in implementing value management through the interview and documentation data gathering process. As a result, it shows that local practitioners of value analysis in construction projects should consider these important factors as a catalyst for increasing the value of projects.
Ethnic Diversity, Civil War and Redistribution

In a game-theoretic framework, we analyse the circumstances under which self-enforcing redistribution and power-sharing coalitions can be used to peacefully resolve ethnic conflict. The existence of a pacific equilibrium depends crucially on ethnic diversity (the number of ethnic groups). The risk of civil war is comparatively high at intermediate levels of ethnic diversity. The risk is low if a society is either very homogeneous or very diverse. Predictions of the model are consistent with evidence on the incidence of civil war.
Sains Humanika To Determine The Effect Of Raters On Science Process Skills Performance Assessment Among Primary School Students

This study is done to know whether the judges’ ratings results in the same decisions for candidates of the same ability and to show the relative severity of the different judges. The Many-facets Rasch Measuring Model (MFRM) is used in this study to determine the validity and reliability of raters’ severity and leniency. The research involves five raters and fifty examinees from standard five students of a primary school in Butterworth. There are five science process skills evaluated that is the observation, classifying, measuring, relationship between space and time and experimenting (identifying variables, make hypothesis, presenting the report). The results of this study suggest that raters of science process skills performance such as those in the PEKA can be trained to rate appropriately and consistently, and that under a system of double marking, assigning different raters to different test takers does not pose a threat to the validity of scores, and that tests are valid, reliable, and fair in that regard.
Identifying Objects in English and German: a Contrastive Linguistic Analysis of Spatial Reference 1

In Tenbrink (2005a), I presented the results of a web study addressing English native speakers' strategies in a scenario that enhances reference via spatial contrast. The present study compares the results for English with those obtained for German, focusing on speakers' linguistic preferences concerning syntactic forms and modifications. Results confirm previously identified communicative principles underlying speakers' choices, and additionally point to a number of systematic differences in speakers' choices, which can in part be explained by differences in language structure.

In this paper we consider a new class of cumulative distribution functions belonging to the important class of functions arising from the theory of impulse techniques, neural networks and debugging theory. By this new family of cumulative functions we study the Hausdorff approximation of the impulse function σ(t). Numerical examples, illustrating our results using the programming environment CAS MATHEMATICA are presented. AMS Subject Classification: 41A46
MPI Flow Analysis Toolbox exploiting pulsed tracer information – an aneurysm phantom proof

Assessment of flow parameters provides insight into (patho-)physiology and thus is a common tool in the field of cardiology to screen for or to evaluate and stage cardiovascular diseases. In this work, we present a Flow Analysis Toolbox for Magnetic Particle Imaging datasets highlighting pulsed tracer information. The presented Tool uses time as well as frequency signal processing approaches and exploits an Optical Flow analysis to extract quantitative 4D velocity vectors fields. In this work, we successfully estimate flow patterns in a nonrealistic aneurysm shaped vessel exploiting pulsed tracer information in the Flow Analysis Toolbox.
The impact of water hyacinth manure on growth attributes and yields in Coriandrum

Experiment was conducted during 2007 and 2008 to study the effect of water hyacinth manure in comparison to control on Coriandrum sativum. Soil mineral analysis test was carried out for soil sample types. Added organic matter, water hyacinth manure in various combinations into soil has been found to influence the performance of crop plants as a result of the increase in nutrient availability. The observations revealed positive response with 100% water hyacinth manure, 50% water hyacinth manure and water hyacinth manure combined with farm yard manure on the growth behaviour of seedlings as they were enhanced significantly compared with that of the seedlings grown in control. The growth and productivity of Coriandrum sativum was more pronounced with 100% water hyacinth manure treatment.
