Hexahedral Meshing With Varying Element Sizes

Hexahedral (or Hex‐) meshes are preferred in a number of scientific and engineering simulations and analyses due to their desired numerical properties. Recent state‐of‐the‐art techniques can generate high‐quality hex‐meshes. However, they typically produce hex‐meshes with uniform element sizes and thus may fail to preserve small‐scale features on the boundary surface. In this work, we present a new framework that enables users to generate hex‐meshes with varying element sizes so that small features will be filled with smaller and denser elements, while the transition from smaller elements to larger ones is smooth, compared to the octree‐based approach. This is achieved by first detecting regions of interest (ROIs) of small‐scale features. These ROIs are then magnified using the as‐rigid‐as‐possible deformation with either an automatically determined or a user‐specified scale factor. A hex‐mesh is then generated from the deformed mesh using existing approaches that produce hex‐meshes with uniform‐sized elements. This initial hex‐mesh is then mapped back to the original volume before magnification to adjust the element sizes in those ROIs. We have applied this framework to a variety of man‐made and natural models to demonstrate its effectiveness.
Importance of the Cutoff Value in the Quadratic Adaptive Integrate-and-Fire Model

Abstract The quadratic adaptive integrate-and-fire model (Izhikevich, 2003, 2007) is able to reproduce various firing patterns of cortical neurons and is widely used in large-scale simulations of neural networks. This model describes the dynamics of the membrane potential by a differential equation that is quadratic in the voltage, coupled to a second equation for adaptation. Integration is stopped during the rise phase of a spike at a voltage cutoff value Vc or when it blows up. Subsequently the membrane potential is reset, and the adaptation variable is increased by a fixed amount. We show in this note that in the absence of a cutoff value, not only the voltage but also the adaptation variable diverges in finite time during spike generation in the quadratic model. The divergence of the adaptation variable makes the system very sensitive to the cutoff: changing Vc can dramatically alter the spike patterns. Furthermore, from a computational viewpoint, the divergence of the adaptation variable implies that the time steps for numerical simulation need to be small and adaptive. However, divergence of the adaptation variable does not occur for the quartic model (Touboul, 2008) and the adaptive exponential integrate-and-fire model (Brette & Gerstner, 2005). Hence, these models are robust to changes in the cutoff value.
Improving RLRN Image Splicing Detection with the Use of PCA and Kernel PCA

Digital image forgery is becoming easier to perform because of the rapid development of various manipulation tools. Image splicing is one of the most prevalent techniques. Digital images had lost their trustability, and researches have exerted considerable effort to regain such trustability by focusing mostly on algorithms. However, most of the proposed algorithms are incapable of handling high dimensionality and redundancy in the extracted features. Moreover, existing algorithms are limited by high computational time. This study focuses on improving one of the image splicing detection algorithms, that is, the run length run number algorithm (RLRN), by applying two dimension reduction methods, namely, principal component analysis (PCA) and kernel PCA. Support vector machine is used to distinguish between authentic and spliced images. Results show that kernel PCA is a nonlinear dimension reduction method that has the best effect on R, G, B, and Y channels and gray-scale images.
The Framing of Decisions and the Rationality of Choice.

Abstract : The psychological principles that govern individual decision making produce predictable reversals of preferences when the same decision problem is framed in different ways. Inconsistencies are illustrated in choices involving monetary outcomes, both hypothetical and real, and in policy questions that pertain to the loss of human lives. Our analysis questions the descriptive adequacy of the standard rational model and highlights the dependence of the normative theory of choice on the psychology of hedonic experience. (Author)

The inner structure of haloes in cold+warm dark matter models

We analyze the properties of dark matter halos in the cold-plus-warm dark matter cosmologies (CWDM). We study their dependence on the fraction and velocity dispersion of the warm particle, keeping the free-streaming scale fixed. To this end we consider three models with the same free-streaming: (1) a mixture of 90% of CDM and 10% of WDM with the mass 1 keV; (2) a mixture of 50% of CDM and 50% of WDM with the mass 5 keV; and (3) pure WDM with the mass 10 keV. "Warm" particles have rescaled Fermi-Dirac spectrum of primordial velocities (as non-resonantly produced sterile neutrinos would have). We compare the properties of halos among these models and with a LCDM with the same cosmological parameters. We demonstrate, that although these models have the same free-streaming length and the suppression of matter spectra are similar at scales probed by the Lyman-alpha forest comoving wave-numbers k<3-5 h/Mpc), the resulting properties of halos with masses below 1e11 Msun are different due to the different behaviour of matter power spectra at smaller scales. In particular, we find that while the number of galaxies remains the same as in LCDM case, their density profiles become much less concentrated, and hence in better agreement with current observational constraints. Our results imply that a single parameter (e.g. free streaming length) description of these models is not enough to fully capture their effects on the structure formation process.
Daily Pedometer Steps among Older Men: Associations with Health-Related Quality of Life and Psychosocial Health

Purpose. To determine the associations of daily pedometer steps with health-related quality of life (HRQoL) and psychosocial health. Design. Cross-sectional. Setting. Alberta, Canada. Subjects. Three hundred eighty-five older-aged men 55 years of age and older. Measures. Subjects completed a mailed survey that assessed HRQoL (RAND-12 Health Status Inventory [RAND-12]), depression, anxiety, and satisfaction with life. Steps/day were assessed with a pedometer via a 3-day step-monitoring period. Analysis. Average pedometer steps/d were categorized into quartiles (Qs). The primary model assessed the association between average pedometer steps/d as the independent variable of interest and our dependent variables of interest (physical, mental, and global health component scores of the RAND-12). Results. For HRQoL, all three adjusted models (i.e., physical, mental, and global health) indicated a significant linear trend between HRQoL indices across pedometer step Qs, with participants in Q3 and Q4 demonstrating higher physical, mental, and global health compared to participants in the lowest Q of pedometer steps (Q1) (all p < .05). For depression, significant differences were observed between Q1 and Q3 (Mdiff = 3.3, p = .006, η2 = .019) and Q1 and Q4 (Mdiff = 2.7, p = .025, η2 = .013). Conclusion. Higher average steps/d were significantly associated with HRQoL across all domains. Older men in the higher Qs of pedometer steps/d reported less depressive symptoms compared to those in the lowest Q of pedometer steps/d.
Binge-Drinking: A Test of the Role of Group Norms in the Theory of Planned Behaviour

A study was undertaken to assess the utility of the theory of planned behaviour in the prediction of students' binge-drinking. Additionally, a perspective was utilised to address the usually weak contribution of subjective norms in predicting behavioural intentions. Respondents were 289 undergraduate students. The study employed a longitudinal design, with the predictors of performing the behaviour under consideration assessed prior to the measure of reported behaviour. Support was found for the application of the theory of planned behaviour to binge-drinking. A reconceptualisation of norms in the theory of planned behaviour, from a social identity theory/self-categorization theory perspective, was also supported; consistent with expectations, the norms of a behaviourally relevant reference group predicted intentions to binge-drink, especially for participants who identified strongly with the reference group. The results are discussed in relation to measures which may help to reduce the incidence of binge-drinking by university students.
Comparing Effects of Intrinsic and Extrinsic Social Values Between Younger and Older Employees

ABSTRACT Socioemotional selectivity theory proposes that older adults emphasize emotional goals and interpersonal closeness to a greater extent than do younger adults, suggesting that holding social work-related values (SWVs) may be beneficial to older employees. This project aimed at examining two dimensions of SWVs, intrinsic and extrinsic SWVs, and tested whether age and work situation would moderate their effects on self-rated job performance. A cross-sectional survey (Study 1, N = 357) and a 14-day experience sampling study (Study 2, N = 77) were conducted among Chinese managerial employees. Study 1 showed that the direct effect of intrinsic SWVs on self-rated job performance was stronger in older employees than in younger employees. Study 2 demonstrated that older employees who valued intrinsic SWVs while being in social situations performed much better than when they did not value intrinsic SWVs but being in social situations; however such positive effect was not shown in younger employees. Findings of this project reveal that the effect of SWVs varies across locus of effect (intrinsic versus extrinsic), age, and work situation. Among older employees, the positive effect of intrinsic SWVs is more crucial than that of extrinsic SWVs on self-rated job performance. Findings of this project imply that intrinsically rewarding incentives would be more effective in motivating older employees to reach peak performance.
Attempted Suicides in India: A Comprehensive Look

Suicide continues to be one of the biggest killers in the world, with suicide rates varying between 8.1 and 58.3/100,000 population for different parts of India. Andhra Pradesh, the fourth largest state in India, is responsible for more than 11% of these. Unfortunately, most suicides are under-reported and there is scant data on attempted suicides. This study aimed to comprehensively study the characteristics of attempted suicides in Andhra Pradesh and using the primary data, make secondary projections for the forthcoming years. Using Patient Care Record (PCR) forms of all emergencies serviced by 108, the first comprehensive emergency service in India, an analysis of all cases was done to detect possible suicides during the period January–December 2007. A follow up 48 hours later was then done to confirm status and diagnosis. A total of 1007 cases were recorded as confirmed suicides. Hanging and insecticide poisoning (72%) were the most common methods used. Males preferred hanging and insecticide poisoning while females preferred self-immolation and hanging as common methods. Self-immolation and insecticide poisoning had the highest mortality (41.6%). Estimates of attempted suicides for the year 2008 revealed a mean of 3.2–3.8 per 1000 population for males, 3.3–3.7 per 1000 population for females and 6.4–7.6 per 1000 population combined. A serious epidemic of suicides seems to be in store in the coming years unless preventive steps in the form of policy changes are undertaken. Restricting access to poisonous substances or prescription drugs and taking into consideration the prevailing social, economic and cultural factors could help in reducing numbers. Starting tele-help services or offering brief interventions during hospital stays are other programs which may be considered.
FRS-DAB Converter for Elimination of Circulation Power Flow at Input and Output Ends

Dual active bridge (DAB) converter is the most suitable converter to transfer high power with bidirectional power flow capability and isolation. However, it has the drawbacks of circulation power flow (CPF) and limited range of zero voltage switching (ZVS). To overcome these drawbacks, several modulation strategies have been proposed; however, the CPF can be eliminated either at input or output voltage ends. In order to eliminate the CPF at both input and output sides, a novel front and rear end switch DAB (FRS-DAB) bidirectional dc–dc converter has been proposed in this paper. It has the advantages of lower current stress, extension of ZVS range, higher power transfer capacity, and improved efficiency compared to the conventional DAB converter. The paper presents the detailed operating modes and analysis of power flow control for the proposed FRS-DAB converter. The operation and analytical results of the proposed converter have been verified through the experimental results using an FPGA Spartan 3AN processor.
Cloning of cDNA and amino acid sequence of a cytokeratin expressed in oocytes of Xenopus laevis.

Using a cDNA clone from the ovary of the frog, Xenopus laevis, we have identified the mRNA and determined the complete amino acid sequence of a major cytoskeletal protein expressed in the oocyte. A comparison with other cytoskeletal proteins of Xenopus and mammals identifies this polypeptide Mr 55,700 as a nonepidermal kind of cytokeratin of the basic (type II) subfamily, which represents the amphibian equivalent to cytokeratin no. 8 of simple epithelia of higher mammals. The sequence data demonstrate the high evolutionary stability of this protein. This cytokeratin and its mRNA are present in oocytes, eggs, embryos, liver, and intestinal mucosa of adult frogs, as well as cultured kidney epithelial cells. We suggest that epithelial cell differentiation in early stages of Xenopus embryogenesis differs from other known pathways of cell differentiation in that major cell-type-specific proteins--i.e., cytokeratins of the simple epithelial type--and their mRNAs are maternally provided and distributed to early epithelial cells by special sorting mechanisms.
Displacement of Tetropium cinnamopterum (Coleoptera: Cerambycidae) by Its Invasive Congener Tetropium fuscum

Abstract We examined the native community of insects interacting with an invasive species, Tetropium fuscum (F.) (Coleoptera: Cerambycidae), in its new range to explore reasons for the invader's relatively slow spread. Tetropium fuscum is a European spruce borer established in Nova Scotia since at least 1990, but it has spread only about 125 km from its site of introduction. We compared the densities of Tetropium spp. , their known parasitoids, and the community of wood-boring insects at sites located within the invasion zone in Nova Scotia versus well outside this zone, in New Brunswick, Canada. Using red spruce trees stressed by girdling or felling, we tested whether: 1) T. fuscum had altered the native wood-boring community; 2) T. fuscum displaced a native congener, Tetropium cinnamopterum (Kirby); and 3) parasitism rates of Tetropium spp. differed between the invaded and noninvaded zones. Both Tetropium spp. and their parasitoid wasps emerged exclusively from felled trees as opposed to girdled trees. We found no difference in community diversity inside versus outside the invasion zone. The combined densities of both Tetropium spp. and their overall parasitism rates also did not differ between zones, but T. cinnamopterum density was significantly greater outside the invasion zone, suggesting T. fuscum may displace the native congener where they are sympatric. Our results suggest that the native and invasive Tetropium spp. act as a single functional species in the invasion zone. We speculate that natural control agents (predators, parasitoids, and competitors) might be limiting the rate of spread of T. fuscum.
Farnesylthiosalicylic acid: inhibition of proliferation and enhancement of apoptosis of hormone-dependent breast cancer cells

Farnesyltransferase inhibitors (FTIs) are being developed to block Ras-mediated actions, but current data suggest that the FTIs act through other non-Ras pathways. A new agent, farnesylthiosalicylic acid (FTS), blocks the binding of Ras to membrane acceptor sites and causes a marked reduction in Ras levels. Accordingly, FTS could be a useful new agent for the treatment of hormone-dependent breast cancer. We examined the dose–response effects of FTS on the growth of MCF-7 breast cancer cells in vitro and in vivo. Further, we dissected out its specific effects on cell proliferation and apoptosis by measuring BrdU incorporation into DNA and by using an ELISA assay to quantitate the magnitude of apoptosis. FTS and its solubilized conjoiner FTS–cyclodextrin markedly inhibited cell growth in MCF-7 breast cancer cells in culture and in xenografts. This agent exerted dual effects to reduce cell proliferation as assessed by BrdU incorporation and to enhance apoptosis as quantitated by ELISA assay. These data suggest that FTS is a promising agent to be developed for treatment of hormone-dependent breast cancer.

Incentive Contracts and Hedge Fund Management

We investigate incentive effects of a typical hedge fund contract for a manager with power utility. With a one-year horizon, the manager displays risk taking that varies dramatically with fund value. We extend the model to multiple yearly evaluation periods and find that the manager's risk taking is rapidly moderated if the fund performs reasonably well. The most realistic approach to modeling fund closure uses an endogenous shutdown barrier where the manager optimally chooses to shut down. The manager increases risk taking as fund value approaches that barrier, and this boundary behavior persists strongly with multiyear horizons.
Changes in secondary structure follow the dissociation of human insulin hexamers: A circular dichroism study

Vacuum UV circular dichroism spectra measured down to 178 nm for hexameric 2‐zinc human insulin, zinc‐free human insulin, and the two engineered and biologically active monomeric mutants, [B/S9D] and [BS9D, T27E] human insulin, show significant differences. The secondary structure analysis of the 2‐zinc human insulin (T6) in neutral solution was determined: 57% helix, 1% β‐strand, 18% turn, and 24% random coil. This is very close to the corresponding crystal structure showing that the solution and solid structures are similar. The secondary structure of the monomer shows a 10–15% increase in antiparallel β‐structure and a corresponding reduction in random coil structure. These structural changes are consistent with an independent analysis of the corresponding difference spectra. The advantage of secondary structure analyses of difference spectra is that the contribution of odd spectral features stemming mainly from side chain chromophores is minimized and the sensitivity of the analyses improved. Analysis of the CD spectra of T6 2‐zinc, zinc‐free human insulin and monomeric mutant insulin by singular value decomposition indicates that the secondary structure changes following the dissociation of hexamers into dimers and monomers are two‐state processes.
Is There Social Capital in a Social Network Site?: Facebook Use and College Students’ Life Satisfaction, Trust, and Participation 1

This study examines if Facebook, one of the most popular social network sites among college students in the U.S., is related to attitudes and behaviors that enhance individuals’ social capital. Using data from a random web survey of college students across Texas (n = 2, 603 ), we ﬁnd positive relationships between intensity of Facebook use and students’ life satisfaction, social trust, civic engagement
Maturity Structure and Supply Factors in Japanese Government Bond Markets

Using our constructed database on the amount outstanding of Japanese Government Bonds (JGBs) categorized by holder and remaining maturity, we examine the effects of changes in the holders and maturity structures on the term structure of interest rates and the risk premium on long-term bonds. Both approaches using single-equation regressions and a term structure model confirm that the net supply of JGBs, the issuance (supply) by the government minus the demand by the preferred-habitat investors including the Bank of Japan (BOJ), had significant effects on long-term interest rates. The regression approach implies that the net supply effects were stronger in the zero interest rate periods, while this relationship was not found using the model approach. We also calculate the net supply effects of the BOJ fs JGB purchases as part of its Quantitative and Qualitative Monetary Easing and compare the results with those obtained from a simple event-study analysis.
