High quality mesh generation for volumetric data processing

High quality tetrahedral/hexahedral mesh generation is important for a wide range of applications in computer graphics, finite element analysis (FEA), physics-based simulation, and solid modeling. Some examples include realistic simulation of deformable objects in computer graphics and numerical solvers for partial differential equations (PDE) in computational science, especially, the FEA. Due to the importance of mesh generation, or meshing, many researchers and practitioners have studied extensively the theory and applications of meshing technologies over the past decades. Automatic generating high quality tetrahedral meshes is a difficult task for a variety of reasons. For examples, there are basic mathematical difficulties which make tetrahedral meshing significantly harder than meshing in 2D: 1) regular tetrahedron, the most isotropic 3D simplex, does not tile 3D space, while the equilateral triangle does tile the plane; 2) unlike the 2D case, even well-spaced vertices can create degenerate 3D elements such as slivers ; 3) dealing with boundaries is also fundamentally more difficult in 3D. The current automatic meshing technologies offer reasonably good solutions for basic linear Finite Element Method (FEM) and basic rendering tasks. More complex analyses and non-linear analyses always require high quality meshes that cannot be generated automatically by current commercial mesh generators. The user still has to spend considerable time and manual labor to make ideal meshes for such analyses. Due to the fast development of 3D scanning devices (such as MRI and CT), it is very common that a scanned data is extremely bulky. Thus, automatic converting and meshing these huge data set is highly desired. The main objective of this thesis is to investigate efficient techniques to construct a high quality tetrahedral mesh for general volume data. We build the quality tetrahedral mesh in two stages: the first stage is automatic low quality tetrahedral mesh generation, and the second stage is mesh quality improvement by using optimization method. i ATTENTION: The Singapore Copyright Act applies to the use of this document.

Utility of fine‐needle aspiration cytology in the diagnosis of HIV lymphadenopathy

India, being a developing country, harbors the third largest human immunodeficiency virus (HIV)‐infected population in the world, and HIV‐associated lymphadenopathy is commonly encountered. HIV lymphadenopathy is more commonly generalized and pathology ranges from reactive lymphoid hyperplasia to infections like tuberculosis to neoplasms such as lymphoma and Kaposi sarcoma. The study intended to assess the utility of fine‐needle aspiration (FNA) cytology in HIV lymphadenopathy.
LIFE HISTORY AND PRODUCTION OF CAPITELLA CAPITATA (CAPITELLIDAE: POLYCHAETA) IN RÍO DE LA PLATA

A benthic survey was carried out from November 1998 to December 1999 in the tidal flats of Bahía Samborombón (Río de la Plata estuary, Argentina), in order to study the population structure, reproductive aspects, growth and secondary production of Capitella capitata (Fabricius, 1780). Growth was analyzed using ELEFAN routine, and the secondary production was estimated by Hynes and Coleman's method (1968). C. capitata did not present periods of very important recruitments throughout the year; however, the abundance of smallest size classes was higher during summer and autumn. The summer cohort showed a growth rate (K) of 2.05 and a seasonal growth oscillation (C) of 0.6, pointing out that worms grew very slowly during winter months. The life span of this cohort was 13 months. The autumn cohort showed a lower growth rate (K= 1.5) and its growth was lowest during winter. The life span was 15 months for this cohort. C. capitata in Punta Rasa presented an extended reproductive period, with absence of activity during winter months. The type of eggs and larvae suggest that C. capitata has benthic larval development in the study area, destining its reproductive effort to the production of a low number of eggs, and assuring larvae survival through incubation in brooding tubes. The annual mean biomass in Punta Rasa was 0.117 g m (AFDW), with a mean secondary production of 0.23 g m y-1 and a P/B ratio of 1.96 y-1. The relatively low density, biomass production and P/B ratio of C. capitata in Punta Rasa can be considered as reference values for this species inhabiting undisturbed or moderately disturbed areas.
Theory and performance of an electrically controlled microwave phase shifter

A microwave phase shifter (MPS) using a dc bias-controlled injection synchronized Gunn oscillator (ISGO) has been proposed. A continuous phase variation of a microwave frequency signal over a range of -π/2 to π/2 can be made by varying the dc bias of the oscillator. Analytically predicted results, verified with the experimental ones obtained in a novel phase-shift measuring set-up, have been described.
On the coincidence of L-functions Dedicated to Professor Masayoshi Nagata on his 60th birthday

In this note, we shall show that (0.2) implies (0.1) (Cor. 4.3). We note that this is a consequence of a group theoretic argument. More generally, let F1 be an algebraic number field of finite degree, F a Galois extension of F1 with the Galois group g and ƒÔ a linear character of F. Here, by a linear character of F, we mean a continuous homomorphism of Gal (F/F) to C•~. For aeg, we denote the conjugate of ƒÔ by ƒÔƒÐ. We assume that
BIOLOGICALLY INSPIRED BIDIRECTIONAL FLUIDIC DIODE

In this paper, we report the development of a biologically inspired fluidic diode motivated by xylem pores in plants. The biologically inspired fluidic diodes allow to design large-scale microfluidic circuits and simple fluidic controls. It requires only a single-layered device and a single pressure source to regulate flow through the entire platform. The operational conditions are precisely estimated based on a fully developed analytical model, which considers the hysteresis of contact angles and effects of fabrication limitations. Using biologically inspired fluidic diodes, we have demonstrated a large-scale spontaneous droplet-patterning and microfluidic co-culture array.
A literature review on the optimization of legged robots

Over the last two decades the research and development of legged locomotion robots has grown steadily. Legged systems present major advantages when compared with ‘traditional’ vehicles, because they allow locomotion in inaccessible terrain to vehicles with wheels and tracks. However, the robustness of legged robots, and especially their energy consumption, among other aspects, still lag behind mechanisms that use wheels and tracks. Therefore, in the present state of development, there are several aspects that need to be improved and optimized. Keeping these ideas in mind, this paper presents the review of the literature of different methods adopted for the optimization of the structure andlocomotion gaits of walking robots. Among the distinct possible strategies often used for these tasks are referred approaches such as the mimicking of biological animals, the use of evolutionary schemes to find the optimal parameters and structures, the adoption of sound mechanical design rules, and the optimization of power-based indexes.
Fabrication of ZnO /Ag Nanocomposite and Their Antibacterial Activities

The ZnO nano powder has been successfully synthesized by a simple hydrothermal technique using zinc acetate and Triethanolamine (TEA) as surfactant agents. The resultant powder was annealed at 140 ᵒC for 12 hours. The as – synthesized ZnO nanopowder was then mixed with AgNO3 to prepare ZnO /Ag nanocomposites. The structural, morphological, and optical properties were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and UV-Visible spectroscopy (UV-Vis). The characterization results confirm that Ag nanoparticles (NPs) have been covered the ZnO hexagonal NPs, and show the red shift with the peak centered at 334 nm, which is due to the interfacial electron coupling between ZnO and Ag NPs, the surface Plasmon peak centered at 403 nm was detected along with the excitonic peak of ZnO confirming the formation of ZnO /Ag nanocomposite. The antibacterial effect of ZnO / Ag nanocomposites was studied for Gram- negative (E.coli) and Gram– positive (Staphylococcus aureus), which showed that the diameter of the inhibition zone of pathogenic bacteria about 15 mm for E.coli and did not show any activity for Staphylococcus aureus.
Arctic cold seeps in marine methane hydrate environments: impacts on shelf macrobenthic community structure offshore Svalbard

Cold seeps are locations where hydrocarbons emanate from the seabed, fueling chemoautotrophic production that may support macrofaunal communities via chemosymbiosis or trophic inter actions. The recent discovery of offshore sub-seabed gas reservoirs and venting methane at the seabed in Svalbard (75 to 79° N) provides the context to examine the influence of cold seeps on macrofaunal community structure in the high-Arctic. We compared benthic macrofaunal community structure from cold-seep environments and paired control stations from 3 regionally distinct areas along the western Svalbard margin and the western Barents Sea. Specialized seep-related polychaetes (e.g. siboglinid tubeworms) were found at seep stations in the Barents Sea in high densities (up to 7272 ind. m−2). The presence of obligate seep-associated faunal taxa demonstrates that chemoautotrophic production, fueled by methane and sulfur, influences benthic communities at these seeps. Further, total biomass was significantly higher at seep-impacted stations compared to controls (mean = 20.7 vs. 9.8 g wet weight sample−1), regardless of region. Four methane seep-influenced samples showed clear indications of seep impact, with reduced diversity and with a few species dominating, compared to controls. Our results demonstrate that the effect of methane seeps on the Svalbard shelf benthic community are highly localized (i.e. meter scale), reflecting strong gradients associated with the point-source impacts of individual seeps. Regional differences and the restricted spatial extent of focused emissions likely drive the observed complexity and heterogeneity at Svalbard cold seeps. These results provide key baseAmerican plaice Hippoglossoides platessoides in a dense field of chemosymbiotic polychaetes at a Svalbard cold seep.

On Keynesian effects of (apparent) non-Keynesian fiscal policies

The aim of the paper is to evaluate the robustness of the theory that claims for restrictive effects of expansionary fiscal policy. It shows that such socalled “non-Keynesian effects” may arise as a consequence of a synchronous and opposite monetary policy intervention. The paper demonstrate this conclusion through a stylized model – supported by an empirical investigation on ECB and FED reaction functions - in which Central Banks take into account deficit spending as an element that generate inflation expectations. The econometric analysis shows also that the ECB reacts asymmetrically to deficit spending variations while the FED has a linear reaction to this indicator.
Asociación de las respuestas fisiológicas a los cambios metabólicos, en el ejercicio físico extenuante

: The purpose of this work was to identify changes in some hematic variables in recreational athletes of middle level competition exposed to exhaustive physical exercise, as well as the association among physiologic changes, personal characteristics, and physical level produced by marathon running. Ten healthy males participated (20-55 years of age). Blood cell count, blood chemistry, lipids, and enzymes were determined. Exercise produced hemoconcentration by reduction in plasma volume (8%; p<0.05). There was significant increment in leukocytes (149%) by neutrophilia (64%) and decrease in lymphocytes (74%). Fibrinogen increased 10.7% (p<0.05). Lipids (CT, C-HDL) did not modify, except C-LDL, which increased significantly (71%), attributing this response to stress of the marathon. Triglyceride decreased 47%. Enzymes increased significantly, particularly CK. Age and physical activity were related with physiologic and metabolic variables, as demonstrated by multivariate analysis. These data contributed to new knowledge in physiologic responses of our ethnic race when exposed to exhaustive exercise such as a marathon. To these results new approaches of risk and different schedules of intervention programs could be generated for better and effective practice of physical exercise in our population.
Spectrum Sharing in Cross-Infrastructure Virtualization using Convex Optimization

Wireless network virtualization enables multiple virtual networks running on a physical network simultaneously by allowing to share wireless substrate resources. The objective of this paper is to efficiently allocate the spectrum resources to multiple virtual networks. In this paper, one virtual network can share the spectrum resources from one or more physical networks as long as the virtual network is in the range of those physical networks in order to increase spectrum utilization. First, the problem is formulated as a convex problem and solve it by using convex optimization solver. Then, simulation is performed to show the revenue of the system in terms of virtual networks.
Square-Root Measurement for Ternary Coherent State Signal

The closed-form expression of the square- root measurement for the ternary coherent state signal {|0⟩, |�⟩, |−�⟩} is derived. Further, the optimal distribution of the ternary coherent state signal that makes the square- root measurement Bayes-optimal is also derived. From a numerical analysis, it is shown that the average probability of error obtained from the square-root measurement and the corresponding optimal distribution provides a good lower bound of the minimax value for the ternary coherent state signal.
Quantifying the size of artefact assemblages

Stone artefacts are broken, burnt and weathered. Processes such as these may act differentially across categories, and will therefore affect interpretations of assemblage size and composition. This paper advocates a more detailed consideration of abundance estimates in artefact analyses, being guided by the understandings built up in archaeological studies of fauna, and begins the process by developing some basic units of measurement for counting flaked stone.
Effect of breastfeeding counseling before cesarean section on initiation time of breastfeeding and newborn’s body temperature in Turkey

Background & Aim: The effect of the anesthetic substance given to the mother during cesarean section, and the pain experienced by the mother after the intervention practiced on the mother during cesarean section delay the mother-infant interaction and the initiation breastfeeding time. This study has been conducted to determine the effects of breastfeeding counseling given to the mothers that gave birth by cesarean section on initiation breastfeeding time and body temperature of newborn in Turkey . Methods & Materials: The study has been conducted in the gynecology and obstetrics service of State Hospital between April 15, 2013, and November 14, 2013, on 95 with suitable criterion for the research (45 experimental and 50 controls) newborns with mothers who have had cesarean birth using quasi-experimental design. In data analysis, frequency distribution, correlation, chisquare test, t-test for independent groups have been used . Results: Initiation breastfeeding time among mothers in the experimental group was 49.97 ± 12.78 minutes which was shorter than in the control group (101.56 ± 42.56 minutes). The incidence of hypothermia in newborns of the control group was significantly higher than those of newborns in the experimental group. As the time of initial breastfeeding got shorter, the body temperature of newborns in control and experimental groups after 30 minutes, the 4 th and 10 th hour after the birth increased . Conclusion: It has been observed that breastfeeding counseling shortens the initial time of breastfeeding, and rises body temperature of the newborn. Breastfeeding counseling is important for early mother-infant interaction after cesarean section, starting breastfeeding within the first 1 hour and protecting the newborn from hypothermia .
Afectividad inducida e impacto en la creatividad, crecimiento personal después del cambio y ajuste percibido al narrar una experiencia emocional intensa

Title: Induced affect impact on creativity, post change personal growth and perceived adjustment after narrating an intense emotional experience. Abstract: An experimental study contrast the effects of inducing positive affect on creativity and the mediational role of positive emotions. High and low positive affect was induced by asking subjects to write three poems Haikus about high (N = 28) and low positive connotation stimuli (N = 28). Then people wrote about their more intense infatuation experience and an- swered a scale on the emotions felt when writing the text, a measure of personal growth or benefits, and a measure of achievement of adaptive goals after the episode. In high positive affect condition was reported more positive and less negative emotions in recounting the experience, more per- sonal growth and a better adjustment. Last poem and narration of experi- ence were evaluated as more original in high positive condition by inde- pendent judges. A mediational analysis showed that positive emotions ex- plain partially the influence of the manipulation on personal growth and perceived adjustment.
Superheating in confined Pb(110) films

The melting behaviour of Pb film embedded in an Al matrix has been investigated by a molecular dynamics simulation technique. The Sutton-Chen potential for alloys has been employed to perform these calculations. Melting of a Pb(110) film has been studied by embedding it in Al(110) and Al(111). Melting is found to initiate at the film-host interface for the Al(110) host. However, a change in orientation of the film is observed before superheating when the film is embedded in the Al(111) matrix. The superheating determined by simulation is comparable with the value calculated by homogeneous theory.
Structural Issues in the Kenyan Financial System: Improving Competition and Access

Although by regional standards, Kenya's financial system is relatively well developed and diversified, major structural impediments prevent it from reaching its full potential. Crosscountry comparisons, however, show the importance of a well-developed financial sector for long-term economic growth and poverty alleviation. Experience from other developing economies has shown the detrimental effect of government ownership and the positive impact that foreign bank ownership can have on the development of a market-based financial system. Analyzing and decomposing the high interest rate spreads and margins in Kenya helps identify structural impediments that drive the high cost of and low access to financial services. The limited information sharing on debtors, deficiencies in the legal and judicial system, the limited number of strong and reputable banks and non-transparency and uncertainty in the banking market are major impediments to the development of Kenya's financial system, to reducing spreads and to widening access.
Rebuilding the Landscape of Psychological Understanding After the Mindreading War

‘Mindreading war’ refers here to the intricate net of connected debates both in the philosophy and the cognitive sciences concerning the onset, the development, and the nature of the cognitive mechanisms underlying mindreading – i.e., the alleged ability to attribute mental states to predict and explain others’ behavior. The mindreading war has lasted for almost forty years by now with apparently no winners or losers. This article argues that the present stalemate results from the lack of initial theoretical discussion about foundational issues that led to the conflict. Recovering the dialogue between psychologists and philosophers is necessary if we are to start rebuilding the landscape of psychological understanding once this long war is over.
Integrated Assessment of the EU’s Greening Reform and Feed Self-Sufficiency Scenarios on Dairy Farms in Piemonte, Italy

Specialised dairy farms are challenged to be competitive and yet respect environmental constrains. A tighter integration of cropping and livestock systems, both in terms of feed and manure flows, can be beneficial for the farm economy and the environment. The greening of the direct payments, which was introduced in the European Union’s greening reform in 2013, is assumed to stimulate the transition towards more sustainable systems. The aim of this study was to quantitatively assess the impacts of greening policies on important economic and environmental indicators of sustainability, and explore potential further improvements in policies. The Farm System SIMulator (FSSIM) bioeconomic farm model was used to simulate the consequences of scenarios of policy change on three representative dairy farms in Piedmont, Italy, i.e., an ‘intensive’, an ‘extensive’, and an ‘organic’ dairy farm. Results showed that in general, there is a large potential to increase the current economic performance of all of the farms. The most profitable activity is milk production, resulting in the allocation of all of the available farm land to feed production. Imposing feed self-sufficiency targets results in a larger adaptation of current managerial practice than the adaptations that are required due to the greening policy scenario. It was shown that the cropping system is not always able to sustain the actual herd composition when 90% feed self-sufficiency is imposed. Regarding the greening policies, it is shown that extensive and organic farms already largely comply with the greening constrains, and the extra subsidy is therefore a bonus, while the intensive farm is likely to sacrifice the subsidy, as adapting the farm plan will substantially reduce profit. The introduction of nitrogen (N)-fixing crops in ecological focus areas was the easiest greening strategy to adopt, and led to an increase in the protein feed self-sufficiency. In conclusion, it is important to note that the greening policy in its current form does not lead to reduced environmental impacts. This implies that in order to improve environmental performance, regulations are needed rather than voluntary economic incentives.
Twitter Mining: The Case of 2014 Indonesian Legislative Elections

Twitter is an online micro blogging and social network which not only for communication with others but twitter can be used for business, administration, or political campaign. This paper concern about twitter for political campaign, we take one case in Indonesian legislative elections. In April 2014, Indonesia has held legislative elections. Fifteen political parties have been participated to this election. Each parties has unique strategic for campaign including social media campaign. In this paper we interested with one of political party which very active in social media campaign especially in Twitter, Partai Keadilan Sejahtera (PKS) or Prosperous Justice Party. This party has a lot of supporters and haters are active tweeting on Twitter about the goodness and badness of this party. This thing begs the question that "Who they are? It is really the voice of Indonesia or just tweets from twitter campaign accounts". This paper tried to answer above question by presenting the result of analysis with empirical data. We collected all tweets which related with this party and then extract the data and classify to two types of twitter accounts: real and campaign accounts. We use some features and Naive Bayes as method for classification. We observe the difference between real and campaign accounts in terms of the tweeting behavior and account properties. We applied text mining methods to know what the meaning of the messages that they bring on their tweets.
