    1997-01-01

    A growing number of nonprofit organizations are being fined for violations of IRS regulations following IRS audits of their tax-deferred annuity (TDA) plans. To ensure that their organizations can withstand the scrutiny of an IRS audit, TDA plan administrators must ensure that plans meet IRS regulations and be prepared for IRS audits. Documentation--particularly of the TDA plan itself, and procedures related to salary reduction programs, compensation limits, excess deferrals and other excess contributions, loans, and distributions--must be comprehensive and in compliance with IRS regulations.

  13. A Unified Pricing of Variable Annuity Guarantees under the Optimal Stochastic Control Framework

    Directory of Open Access Journals (Sweden)

    Pavel V. Shevchenko

    2016-07-01

    Full Text Available In this paper, we review pricing of the variable annuity living and death guarantees offered to retail investors in many countries. Investors purchase these products to take advantage of market growth and protect savings. We present pricing of these products via an optimal stochastic control framework and review the existing numerical methods. We also discuss pricing under the complete/incomplete financial market models, stochastic mortality and optimal/sub-optimal policyholder behavior, and in the presence of taxes. For numerical valuation of these contracts in the case of simple risky asset process, we develop a direct integration method based on the Gauss-Hermite quadratures with a one-dimensional cubic spline for calculation of the expected contract value, and a bi-cubic spline interpolation for applying the jump conditions across the contract cashflow event times. This method is easier to implement and faster when compared to the partial differential equation methods if the transition density (or its moments of the risky asset underlying the contract is known in closed form between the event times. We present accurate numerical results for pricing of a Guaranteed Minimum Accumulation Benefit (GMAB guarantee available on the market that can serve as a numerical benchmark for practitioners and researchers developing pricing of variable annuity guarantees to assess the accuracy of their numerical implementation.

    2016-03-18

    We introduce deferred warping, a novel approach for real-time deformation of 3D objects attached to an animated or manipulated surface. Our target application is virtual prototyping of garments where 2D pattern modeling is combined with 3D garment simulation which allows an immediate validation of the design. The technique works in two steps: First, the surface deformation of the target object is determined and the resulting transformation field is stored as a matrix texture. Then the matrix texture is used as look-up table to transform a given geometry onto a deformed surface. Splitting the process in two steps yields a large flexibility since different attachment types can be realized by simply defining specific mapping functions. Our technique can directly handle complex topology changes within the surface. We demonstrate a fast implementation in the vertex shading stage allowing the use of highly decorated surfaces with millions of triangles in real-time.

  18. Immunization and Hedging of Post Retirement Income Annuity Products

    Directory of Open Access Journals (Sweden)

    Changyu Liu

    2017-03-01

    Full Text Available Designing post retirement benefits requires access to appropriate investment instruments to manage the interest rate and longevity risks. Post retirement benefits are increasingly taken as a form of income benefit, either as a pension or an annuity. Pension funds and life insurers offer annuities generating long term liabilities linked to longevity. Risk management of life annuity portfolios for interest rate risks is well developed but the incorporation of longevity risk has received limited attention. We develop an immunization approach and a delta-gamma based hedging approach to manage the risks of adverse portfolio surplus using stochastic models for mortality and interest rates. We compare and assess the immunization and hedge effectiveness of fixed-income coupon bonds, annuity bonds, as well as longevity bonds, using simulations of the portfolio surplus for an annuity portfolio and a range of risk measures including value-at-risk. We show how fixed-income annuity bonds can more effectively match cash flows and provide additional hedge effectiveness over coupon bonds. Longevity bonds, including deferred longevity bonds, reduce risk significantly compared to coupon and annuity bonds, reflecting the long duration of the typical life annuity and the exposure to longevity risk. Longevity bonds are shown to be effective in immunizing surplus over short and long horizons. Delta gamma hedging is generally only effective over short horizons. The results of the paper have implications for how providers of post retirement income benefit streams can manage risks in demanding conditions where innovation in investment markets can support new products and increase the product range.

    本文对提供最低提取利益保证的变额年金保险进行了深入分析,总结了最低提取利益保证的主要特征(重置条款、奖励条款、惩罚条款),并将这些特征进行了定量的分析。本文在DanielBauer等(2006)提出的定价模型的基础上进行了创新和改进,在定价过程中加入了国外年金市场上通行的最低提取利益保证的三大主要特征,研究出一套可操作性较强的定价方法,旨在为将来国内保险公司设计开发此类产品时,提供一些建议和理论指导参考。%China has launched a pilot project on Variable Annuities since May 2010, trying to enrich the product mix and establish a multi-level product structure to cater to the need of different levels of consumers. A variable annuities policy is a financial contract between a policyholder and an insurance company which promises a stream of annuities cash flows. At the initiation of the contract, the policyholder pays a single lump sum premium to the issu er. The trusted fund is then invested in a well diversified reference portfolio of a specific class of assets. Under the policy, the insurer promises to make variable periodic payments to the policyholder on preset future dates. The variable payments would depend on the performance of the reference portfolio, thus the policyholders are provided with the equity participation. Variable Annuity products are the mainstream pension products abroad, among all the guarantees the most popular one is guaranteed minimum withdrawal benefit (GMWB) ,which is also at the greatest risk. A GMWB provides the policyholder with the right to withdraw the initial investment over a certain period of time, irrespective of investment performance, as long as annual withdrawals do not exceed a pre-specified amount. To finance these guarantees, most commonly insurers continuously deduct an option fee at a constant rate from the policyholder's ac- count value. China

    Although lesions deferred revascularization following fractional flow reserve (FFR) assessment have a low risk of adverse cardiac events, variability in risk for deferred lesion intervention (DLI) has not been previously evaluated. The aim of this study was to develop a prediction model to estimate 1-year risk of DLI for coronary lesions where revascularization was not performed following FFR assessment. A prediction model for DLI was developed from a cohort of 721 patients with 882 coronary lesions where revascularization was deferred based on FFR between 10/2002 and 7/2010. Deferred lesion intervention was defined as any revascularization of a lesion previously deferred following FFR. The final DLI model was developed using stepwise Cox regression and validated using bootstrapping techniques. An algorithm was constructed to predict the 1-year risk of DLI. During a mean (±SD) follow-up period of 4.0 ± 2.3 years, 18% of lesions deferred after FFR underwent DLI; the 1-year incidence of DLI was 5.3%, while the predicted risk of DLI varied from 1 to 40%. The final Cox model included the FFR value, age, current or former smoking, history of coronary artery disease (CAD) or prior percutaneous coronary intervention, multi-vessel CAD, and serum creatinine. The c statistic for the DLI prediction model was 0.66 (95% confidence interval, CI: 0.61-0.70). Patients deferred revascularization based on FFR have variation in their risk for DLI. A clinical prediction model consisting of five clinical variables and the FFR value can help predict the risk of DLI in the first year following FFR assessment.

    2013-01-01

    The loss or mutilation of a breast as a result of surgical treatment of neoplastic disease always represents a negative impact on a woman's psyche and negatively influences the quality of the woman's remaining life. The goal of our work was to implement deferred breast reconstruction into routine practice and the objectification of the influence of reconstruction on bodily integrity, quality of life, and the feeling of satisfaction in women. Women in remission from neoplastic disease after a radical mastectomy were indicated for breast reconstruction. Between January 2002 and December 2011 deferred breast reconstruction was carried out 174 × on 163 women, with an average age of 49.2 and an age range of 29-67 years. The most frequently used reconstruction method was a simple gel augmentation of the breast or a Becker expander/implant - 51 (29.3%) and 37 (21.3%), or in combination with a lateral thoracodorsal flap (31; 17.8% and 47; 27%); reconstruction using a free DIEP flap was carried out 7 × (4%). Complications occurred in 19 operations (10.9%) with a dominance of inflammation and pericapsular fibrosis, in a subjective analysis, satisfaction with the results prevailed, along with an increased quality of life after reconstruction. A growing number of deferred breast reconstructions, women's satisfaction with the results, the positive influence of renewed bodily integrity on the feeling of life satisfaction and the quality of life have elevated breast reconstructions to a qualitatively higher level.

  3. How to avoid deferred-compensation troubles.

    Science.gov (United States)

    Freeman, Todd I

    2005-06-01

    Executive compensation packages have long included stock options and deferred compensation plans in order to compete for talent. Last year, Congress passed a law in response to the Enron debacle, in which executives were perceived to be protecting their deferred compensation at the expense of employees, creditors, and investors. The new law is designed to protect companies and their shareholders from being raided by the very executives that guided the company to financial ruin. Physicians who are part owners of medical practices need to know about the changes in the law regarding deferred compensation and how to avoid costly tax penalties. This article discusses how the changes affect medical practices as well as steps physician-owned clinics can take to avoid the risk of penalty, such as freezing deferred compensation and creating a new deferred compensation plan.

    2001-01-01

    The dual random models about the life insurance and social pension insurance have received considerable attention in the recent articles on actuarial theory and applications. This paper discusses a general kind of increasing annuity based on its force of interest accumulationfunction as a general random process. The dual random model of the present value of the benefits of the increasing annuity has been set, and their moments have been calculated under certainconditions.

  11. Pulsed feedback defers cellular differentiation.

    Directory of Open Access Journals (Sweden)

    Joe H Levine

    2012-01-01

    Full Text Available Environmental signals induce diverse cellular differentiation programs. In certain systems, cells defer differentiation for extended time periods after the signal appears, proliferating through multiple rounds of cell division before committing to a new fate. How can cells set a deferral time much longer than the cell cycle? Here we study Bacillus subtilis cells that respond to sudden nutrient limitation with multiple rounds of growth and division before differentiating into spores. A well-characterized genetic circuit controls the concentration and phosphorylation of the master regulator Spo0A, which rises to a critical concentration to initiate sporulation. However, it remains unclear how this circuit enables cells to defer sporulation for multiple cell cycles. Using quantitative time-lapse fluorescence microscopy of Spo0A dynamics in individual cells, we observed pulses of Spo0A phosphorylation at a characteristic cell cycle phase. Pulse amplitudes grew systematically and cell-autonomously over multiple cell cycles leading up to sporulation. This pulse growth required a key positive feedback loop involving the sporulation kinases, without which the deferral of sporulation became ultrasensitive to kinase expression. Thus, deferral is controlled by a pulsed positive feedback loop in which kinase expression is activated by pulses of Spo0A phosphorylation. This pulsed positive feedback architecture provides a more robust mechanism for setting deferral times than constitutive kinase expression. Finally, using mathematical modeling, we show how pulsing and time delays together enable "polyphasic" positive feedback, in which different parts of a feedback loop are active at different times. Polyphasic feedback can enable more accurate tuning of long deferral times. Together, these results suggest that Bacillus subtilis uses a pulsed positive feedback loop to implement a "timer" that operates over timescales much longer than a cell cycle.

  13. Pension Demand and Utility: The Life Annuity Puzzle

    OpenAIRE

    This paper shows by means of the concept of utility that annuitization through life annui-ties or a pension can be an efficient instrument for the economic assurance of seniors. Various quantitative arguments are presented supporting this statement (e.g. annuity equivalent wealth [AEW] is calculated using Czech data). In conclusion, some practical arguments are mentioned regarding why the real demand on life annuities contradicts this result so that a so-called annuity puzzle arises in pensio...

    Using UK microeconomic data, we analyze the empirical determinants of voluntary annuity market demand. We find that annuity market participation increases with financial wealth, life expectancy and education and decreases with other pension income and a possible bequest motive for surviving spouses. We then show that these empirically-motivated determinants of annuity market participation have the same, quantitatively important, effects in a life-cycle model of annuity and life insurance dema...

  5. An FFT Approach to Price Guaranteed Minimum Death Benefit in Variable Annuities under a Regime-Switching Model%体制转换模型下具备最低身故利益保证的变额年金的定价

    Institute of Scientific and Technical Information of China (English)

    范堃

    2013-01-01

    This paper considers the valuation of guaranteed minimum death benefit in variable annuities under a regime-switching model. More specifically, the risk-free interest rate, the appreciation rate and the volatility of the reference investment fund are modulated by a continuous-time, finite-state, observable Markov chain. A regime-switching Esscher transform is adopted to select an equiva-lent martingale measure in the incomplete financial market. Inverse Fourier transform is used to derive an analytical pricing formula for the embedded option in variable annuity with guaranteed minimum death benefit. To calculate the fair guarantee charge, fast Fourier transform approach is applied. Numerical examples are provided to illustrate the practical implementation and the relationship between the fair guarantee charges and other parameters.%本文研究具备最低身故利益保证的变额年金的定价问题。该模型中,假设无风险利率,投资基金的波动率是被连续时间有限状态马尔科夫链所调制的。运用体制转换Esscher变换方法得到唯一的等价鞅测度。在风险中性测度下,通过逆傅里叶变换得到最低身故利益保证的变额年金中嵌入期权的定价公式,然后通过快速傅里叶变换进行求解,并对数值例子进行了分析比较。

    Longevity risk has become a major challenge for governments, individuals, and annuity providers in most countries, and especially its aggregate form, i.e. the risk of unsystematic changes to general mortality patterns, bears a large potential for accumulative losses for insurers. As obvious risk management tools such as (re)insurance or hedging are less suited to manage an annuity provider’s exposure to aggregate longevity risk, the current paper proposes a new type of life annuities with ben...

    徐景峰; 李玉龙

    2016-01-01

    The policy of deferred-tax on commercial endowment insurance is of great importance to the establishment and im⁃provement of pension system. In this paper, two different individual consumption-saving models, which are named as non-tax deferred model and tax deferred model, are built separately to study the effect of deferred-tax policy on optimal individual choices. Through modeling process, we come to the following conclusions:If the deferred tax rate equals the working period tax rate, individual demand for annuity insurance will increase, and yet the other demand and his/her expected utility will keep sta⁃ble. In this situation, the deferred tax policy is an Pareto improvement;If it is less than the working period tax rate, individual working period consumption, demand for annuity insurance and his expected utility will increase while individual bank saving will decrease;If it is greater than the working period tax rate, individual working period consumption, demand for annuity in⁃surance and his/her expected utility will decrease but individual bank savings will increase.%商业养老保险税收递延政策对完善养老保障体系具有重要意义。文章分别在无税收递延政策和有税收递延政策情形下建立了个体消费—储蓄模型,通过对比两种情形下的个体最优行为,分析了税收递延政策对个体行为的影响。研究表明:当递延税收税率与工作期税率相等时,个体年金保险需求增加、其他行为及效用不变,此时税收递延政策是一种帕累托改进;当递延税收税率小于工作期税率时,个体当期消费、年金保险需求及效用增加,银行存款减少;当递延税收税率大于工作期税率时,个体当期消费、年金保险需求及效用减少,银行存款增加。

  2. Different supplents for finishing of Nellore cattle on deferred Brachiaria decumbens pasture during the dry season

    Directory of Open Access Journals (Sweden)

    Antonio Tadeu de Andrade

    2015-07-01

    Full Text Available This study evaluated the effect of four types of supplement on the finishing of Nellore cattle on deferred Brachiaria decumbens pasture during the dry season. Sixty-four castrated Nellore males with an age of approximately 34 months and initial body weight (BW ranging from 360 to 380 kg were divided into 16 animals per treatment in a completely randomized design. The treatments consisted of four types of pasture supplement: deferred Brachiaria decumbens pasture + energy protein mineral salt (SuEPM used as control; deferred Brachiaria decumbens pasture + urea + cottonseed meal (28% CP + ground corn grain (SuCo; deferred Brachiaria decumbens pasture + urea + cottonseed meal (28% CP + citrus pulp (SuCPu; deferred Brachiaria decumbens pasture + urea + cottonseed meal (28% CP + soy hull (SuSH. The pasture was deferred for 170 days and provided 3,482 kg DM/ha of forage, permitting a stocking rate of 1.56 AU/ha (DM intake of 2.25% BW and 50% pasture efficiency. The animals received the supplement ad libitum in the SuEPM treatment and as % BW in the other treatments from July to October. The animals were slaughtered at a minimum BW of 457 kg. The following variables were evaluated: final weight, weight gain during the period (WG, average daily gain (ADG, hot carcass weight (HCW, and hot carcass yield (HCY. With respect to final weight, the supplement in the SuCo, SuCPu and SuSH treatments permitted a greater supply of nutrients and the animals therefore exhibited better performance (P<0.05 compared to the SuEPM treatment (mean of 478.68 vs 412.62 kg. The same effect was observed for the other parameters studied. Analysis of WG and ADG showed that SuSH was superior to the SuCo and SuCPu treatments (P<0.05 due to the increased offer of concentrate and SuEPM was inferior to the other treatments. Higher HCW (260.05 kg and HCY (53.92% were obtained with treatment SuSH as a result of greater performance. Supplementation of cattle during the dry period on

  9. Deferred Executive Compensation Policies in Chinese State-owned Enterprises

    Institute of Scientific and Technical Information of China (English)

    Min Ju

    2007-01-01

    Since the commencement of industrial reform in China, most Chinese state-owned enterprises have adopted a deferred executive compensation policy to provide incentives for their management teams. However, the effectiveness of such a policy needs to be evaluated In this paper, we specify a model of deferred executive compensation policy, in which the compensation for executives is contingent on firms 'future revenue. The model suggests that under deferred executive compensation policies, managers exhibit an increasing level of effort in every period. Furthermore, the deferred compensation policy encourages managers to make long-term investments, which might generate revenue even after the termination of managerial contracts.

    2015-09-02

    Convergence of spectral deferred correction (SDC), where low-order time integration methods are used to construct higher-order methods through iterative refinement, can be accelerated in terms of computational effort by using mixed-precision methods. Using ideas from multi-level SDC (in turn based on FAS multigrid ideas), some of the SDC correction sweeps can use function values computed in reduced precision without adversely impacting the accuracy of the final solution. This is particularly beneficial for the performance of combustion solvers such as S3D [6] which require double precision accuracy but are performance limited by the cost of data motion.

  13. Economic viability of production of Nellore heifers on Urochloa brizantha cv. Marandu pastures deferred and fertilized with nitrogen

    2016-01-01

    Full Text Available The objective of this study was to evaluate the effect of different levels of nitrogen on deferred pastures of Urochloa brizantha cv. Marandu, and the implications on the economic viability of production of Nellore heifers. This was a completely randomized design with four treatments (T1 = deferred pasture without nitrogen fertilization; T2 = deferred pasture fertilized with 50 kg N ha-1, T3 = deferred pasture with 100 kg N ha-1, T4 = deferred pasture with 150 kg N ha-1 and four replications (16 fertilized paddocks. First, there were used 48 Nellore heifers, average eight months of age and initial body weight of 178.69 ± 26.67 kg, with three heifers in each paddock, in all treatments, in a continuous grazing system, with variable stocking rate. Only the treatment the without nitrogen fertilization showed negative monetary values of R$ -181.96, R$ ha-1 -72.79 and R$ @-1 -32.11. The treatment with 50 kg N ha-1 achieved the highest positive monetary values of R$ 756.02, R$ ha-1 302.40 and R$ @-1 50.52. Economic viability data in beef heifer production demonstrate that the treatment with 50 kg N ha-1 is the most financially viable under the conditions of this study.

    Full Text Available The article highlights the results of the analysis of deferred taxes as indicators of the accounting financial statements, reflecting payments to the budget for income tax agricultural organizations. The importance of deferred tax assets and deferred tax liabilities as a key marker of efficiency of the tax policy of the agricultural organizations is emphasized. Its inefficiency can be judge by excess of deferred tax assets over deferred tax liabilities, which is seen as a temporary diversion of funds from the market, which has zero profitability. The conclusion was made about the improvement of financial stability and liquidity of the organization under the influence of deferred tax liabilities and the deteriorating financial situation, financial stability and liquidity under the influence of deferred tax assets. The effective income tax rate of the agricultural organizations of Krasnodar territory is determined; it does not exceed 3% and differs from general because of tax benefits, deductions and tax policy. The basic causes of appearance of temporary differences are identified by types in the account of the agricultural organizations. Typical errors in accounting for deferred taxes are described. A refined form of the report on financial results containing transcript of profit before tax from non-agricultural activities, with the aim of monitoring the relationship of accounting and taxable profit in the agricultural organizations

  13. Analysis of Deferred Taxes in the Business Environment in Serbia

    Savka VUČKOVIĆ-MILUTINOVIĆ

    2013-06-01

    Full Text Available Flow-through model of income tax reporting in general purpose financial statements had a long history of use in Serbia. It was only in 2004 (and 2003 for banks, when the implementation of deferred taxes model started. It was inevitable, because IAS/IFRS became mandatory basis for preparing financial statements. In this paper we examine quality of deferred taxes disclosures in the financial statements of companies in Serbia. We also documented the most common temporary differences that arise in measuring accounting and taxable income and in that way we identified the major sources of deferred tax. We analyzed the materiality of deferred taxes and their effect on company´s performance in Serbia.

  1. Frailty and Risk Classification for Life Annuity Portfolios

    Directory of Open Access Journals (Sweden)

    Annamaria Olivieri

    2016-10-01

    Full Text Available Life annuities are attractive mainly for healthy people. In order to expand their business, in recent years, some insurers have started offering higher annuity rates to those whose health conditions are critical. Life annuity portfolios are then supposed to become larger and more heterogeneous. With respect to the insurer’s risk profile, there is a trade-off between portfolio size and heterogeneity that we intend to investigate. In performing this, there is a second and possibly more important issue that we address. In actuarial practice, the different mortality levels of the several risk classes are obtained by applying adjustment coefficients to population mortality rates. Such a choice is not supported by a rigorous model. On the other hand, the heterogeneity of a population with respect to mortality can formally be described with a frailty model. We suggest adopting a frailty model for risk classification. We identify risk groups (or classes within the population by assigning specific ranges of values to the frailty within each group. The different levels of mortality of the various groups are based on the conditional probability distributions of the frailty. Annuity rates for each class then can be easily justified, and a comprehensive investigation of insurer’s liabilities can be performed.

  13. Mathematics-for-teaching: Insights from the case of annuities

    Directory of Open Access Journals (Sweden)

    Craig Pournara

    2014-05-01

    Full Text Available Shulman’s notations of subject matter knowledge (SMK and pedagogical content knowledge (PCK have been very influential in education research on teachers’ knowledge for teaching. However, there is little empirical evidence in support of these as separate analytical constructs. Furthermore, attempts to distinguish SMK and PCK highlight the complex and multidimensional nature of teachers’ knowledge and hence the difficulty of separating SMK and PCK. The author adopts the notion of mathematics-for-teaching (MfT and argues that teachers’ knowledge for teaching annuities comprises knowledge of mathematical aspects, knowledge of pedagogical aspects and contextual knowledge of finance. Drawing from a larger study in which the author taught a financial mathematics course to pre-service secondary mathematics teachers, four examples of teachers’ knowledge for teaching annuities are identified, each of which illustrates how knowledge of mathematics, knowledge of pedagogy and contextual knowledge of finance are intertwined.

  12. Revisionist integral deferred correction with adaptive step-size control

    KAUST Repository

    2015-03-27

    © 2015 Mathematical Sciences Publishers. Adaptive step-size control is a critical feature for the robust and efficient numerical solution of initial-value problems in ordinary differential equations. In this paper, we show that adaptive step-size control can be incorporated within a family of parallel time integrators known as revisionist integral deferred correction (RIDC) methods. The RIDC framework allows for various strategies to implement stepsize control, and we report results from exploring a few of them.

  19. Survival after primary and deferred cystectomy for stage T1 transitional cell carcinoma of the bladder

    Directory of Open Access Journals (Sweden)

    Conclusions: Cancer-specific survival is statistically comparable for primary and deferred cystectomy in T1 bladder cancer, although there is a non-significant difference in favor of primary cystectomy. In the deferred cystectomy group, the number of TURBTs beyond three is associated with lower survival. Conservative treatment should be adopted for most cases in this category.

  6. Performance of Lempel-Ziv compressors with deferred innovation

    Science.gov (United States)

    Cohn, Martin

    1989-01-01

    The noiseless data-compression algorithms introduced by Lempel and Ziv (LZ) parse an input data string into successive substrings each consisting of two parts: The citation, which is the longest prefix that has appeared earlier in the input, and the innovation, which is the symbol immediately following the citation. In extremal versions of the LZ algorithm the citation may have begun anywhere in the input; in incremental versions it must have begun at a previous parse position. Originally the citation and the innovation were encoded, either individually or jointly, into an output word to be transmitted or stored. Subsequently, it was speculated that the cost of this encoding may be excessively high because the innovation contributes roughly 1g(A) bits, where A is the size of the input alphabet, regardless of the compressibility of the source. To remedy this excess, it was suggested to store the parsed substring as usual, but encoding for output only the citation, leaving the innovation to be encoded as the first symbol of the next substring. Being thus included in the next substring, the innovation can participate in whatever compression that substring enjoys. This strategy is called deferred innovation. It is exemplified in the algorithm described by Welch and implemented in the C program compress that has widely displaced adaptive Huffman coding (compact) as a UNIX system utility. The excessive expansion is explained, an implicit warning is given against using the deferred innovation compressors on nearly incompressible data.

  7. Donating blood for research: a potential method for enhancing customer satisfaction of permanently deferred blood donors.

    Science.gov (United States)

    Waller, Daniel; Thijsen, Amanda; Garradd, Allira; Hayman, Jane; Smith, Geoff

    2015-11-30

    Each year, a large number of individuals in Australia are deferred from donating blood. A deferral may have a negative impact on donor satisfaction and subsequent word-of-mouth communication. The Australian Red Cross Blood Service (the Blood Service) is, therefore, investigating options for managing service interactions with deferred donors to maintain positive relationships. While public research institutes in Australia have established independent research donor registries, other countries provide programmes allowing deferred donors to donate blood for research via blood collection agencies. This study examined attitudes towards donating blood for research use in a sample of permanently deferred Australian donors. Donors permanently deferred because of a risk of variant Creutzfeldt-Jakob disease (n=449) completed a postal survey that examined attitudes towards research donation. The majority of participants were interested in donating blood for research (96%), and joining a registry of research donors (93%). Participants preferred to donate for transfusion or clinical research, and were willing to travel large distances. Results indicated that positive attitudes towards the Blood Service would be extended if the opportunity to donate blood was provided. These findings indicate a desire for continued engagement with the Blood Service despite deferral. Donating blood for research is a potential way of maintaining positive relationships with permanently deferred donors which also benefits the health research community. Through maintaining positive relationships with deferred donors, positive word-of-mouth activity can be stimulated. Further work is needed to determine the feasibility of implementing research donation through the Blood Service in Australia.

  8. Cost-effectiveness analysis of ranibizumab plus prompt or deferred laser or triamcinolone plus prompt laser for diabetic macular edema.

    Perform a cost-effectiveness analysis of the treatment of diabetic macular edema (DME) with ranibizumab plus prompt or deferred laser versus triamcinolone plus prompt laser. Data for the analysis were drawn from reports of the Diabetic Retinopathy Clinical Research Network (DRCRnet) Protocol I. Computer simulation based on Protocol I data. Analyses were conducted from the payor perspective. Simulated participants assigned characteristics reflecting those seen in Protocol I. Markov models were constructed to replicate Protocol I's 104-week outcomes using a microsimulation approach to estimation. Baseline characteristics, visual acuity (VA), treatments, and complications were based on Protocol I data. Costs were identified by literature search. One-way sensitivity analysis was performed, and the results were validated against Protocol I data. Direct cost of care for 2 years, change in VA from baseline, and incremental cost-effectiveness ratio (ICER) measured as cost per additional letter gained from baseline (Early Treatment of Diabetic Retinopathy Study). For sham plus laser (S+L), ranibizumab plus prompt laser (R+pL), ranibizumab plus deferred laser (R+dL), and triamcinolone plus laser (T+L), effectiveness through 104 weeks was predicted to be 3.46, 7.07, 8.63, and 2.40 letters correct, respectively. The ICER values in terms of dollars per VA letter were $393 (S+L vs. T+L), $5943 (R+pL vs. S+L), and $20 (R+dL vs. R+pL). For pseudophakics, the ICER value for comparison triamcinolone with laser versus ranibizumab with deferred laser was $14 690 per letter gained. No clinically relevant changes in model variables altered outcomes. Internal validation demonstrated good similarity to Protocol I treatment patterns. In treatment of phakic patients with DME, ranibizumab with deferred laser provided an additional 6 letters correct compared with triamcinolone with laser at an additional cost of $19 216 over 2 years. That would indicate that if the gain in VA seen at 2 years

  9. Seduction trauma: representation, deferred action, and pathogenic development.

    Science.gov (United States)

    Blum, H P

    1996-01-01

    Seduction trauma refers to a range of phenomena currently described under the rubric of child abuse. Freud elucidated the fantasy distortion and elaboration of traumatic experience and retained the importance of actual trauma. Psychic trauma is associated with the alteration of self and object representations and ensuing new identifications, e.g., with victim and aggressor. The "deferred action" of psychic trauma is an antiquated concept and psychic trauma has immediate effects as well as far reaching developmental consequences. Prior trauma predisposes to later traumatic vulnerability and to trauma linked to phase specific unconscious conflict. The pathogenesis of child sex abuse and the enactment of oedipal incest extends before and after the oedipal phase, is often associated with other forms of abuse, and has a history of pathogenic parent-child relationship.

While public research institutes in Australia have established independent research donor registries, other countries provide programmes allowing deferred donors to donate blood for research via blood collection agencies. This study examined attitudes towards donating blood for research use in a sample of permanently deferred Australian donors. Materials and methods Donors permanently deferred because of a risk of variant Creutzfeldt-Jakob disease (n=449) completed a postal survey that examined attitudes towards research donation. Results The majority of participants were interested in donating blood for research (96%), and joining a registry of research donors (93%). Participants preferred to donate for transfusion or clinical research, and were willing to travel large distances. Results indicated that positive attitudes towards the Blood Service would be extended if the opportunity to donate blood was provided. These findings indicate a desire for continued engagement with the Blood Service despite deferral. Discussion Donating blood for research is a potential way of maintaining positive relationships with permanently deferred donors which also benefits the health research community. Through maintaining positive relationships with deferred donors, positive word-of-mouth activity can be stimulated. Further work is needed to determine the feasibility of implementing research donation through the Blood Service in Australia. PMID:26674813

    2015-06-01

    Nucleic acid amplification tests (NAATs) are recommended for the diagnosis of N. gonorrhoeae infections because of their superior sensitivity. Increasing NAAT use causes a decline in crucial antimicrobial resistance (AMR) surveillance data, which rely on culture. We analyzed the suitability of the ESwab system for NAAT diagnostics and deferred targeted N. gonorrhoeae culture to allow selective and efficient culture based on NAAT results. We included patients visiting the STI Clinic Amsterdam, The Netherlands, in 2013. Patient characteristics and urogenital and rectal samples for direct N. gonorrhoeae culture, standard NAAT, and ESwab were collected. Standard NAAT and NAAT on ESwab samples were performed using the Aptima Combo 2 assay for N. gonorrhoeae and C. trachomatis. Two deferred N. gonorrhoeae cultures were performed on NAAT-positive ESwab samples after storage at 4°C for 1 to 3 days. We included 2,452 samples from 1,893 patients. In the standard NAAT, 107 samples were N. gonorrhoeae positive and 284 were C. trachomatis positive. The sensitivities of NAAT on ESwab samples were 83% (95% confidence interval [CI], 75 to 90%) and 87% (95% CI, 82 to 90%), respectively. ESwab samples were available for 98 of the gonorrhea-positive samples. Of these, 82% were positive in direct culture and 69% and 56% were positive in the 1st and 2nd deferred cultures, respectively (median storage times, 27 and 48 h, respectively). Deferred culture was more often successful in urogenital samples or when the patient had symptoms at the sampling site. Deferred N. gonorrhoeae culture of stored ESwab samples is feasible and enables AMR surveillance. To limit the loss in NAAT sensitivity, we recommend obtaining separate samples for NAAT and deferred culture.

  5. Outcomes of coronary stenoses deferred revascularization for borderline versus nonborderline fractional flow reserve values.

    Current evidence supports deferral of revascularization for lesions with fractional flow reserve (FFR) values >0.80. The natural history after deferral of revascularization of lesions with borderline FFR values is unknown. This study evaluated the outcomes of patients after deferred revascularization of coronary stenoses based on a borderline FFR value. We retrospectively studied 720 patients with 881 intermediate-severity coronary stenoses who underwent FFR assessment from October 2002 to July 2010 and were deferred revascularization. Patients were divided into gray zone (0.75 to 0.80), borderline (0.81 to 0.85), and nonborderline (>0.85) FFR groups. Any subsequent percutaneous coronary intervention or coronary artery bypass grafting of a deferred stenosis during follow-up was classified as a deferred lesion intervention (DLI). Patient and/or lesion characteristics and clinical outcomes were compared between the FFR groups using univariate and propensity score-adjusted inverse probability of weighting Cox proportional hazards analyses. During a mean follow-up of 4.5 ± 2.1 years, 157 deferred lesions (18%) underwent DLI by percutaneous coronary intervention (n = 117) or coronary artery bypass grafting (n = 40). No statistically significant differences were observed in clinical outcomes between the gray zone and borderline FFR groups. Lesions with a borderline FFR were associated with a significantly higher risk of DLI compared with lesions with nonborderline FFR values (hazard ratio 1.63, 95% confidence interval 1.14 to 2.33, p = 0.007). Lesions deferred revascularization because of a borderline FFR (0.81 to 0.85) were associated with a higher risk of DLI compared with lesions with a nonborderline FFR (>0.85). Further study is needed to determine the optimal management of coronary stenoses with a borderline FFR value. Copyright © 2014 Elsevier Inc. All rights reserved.

  5. The impact of excess choice on deferment of decisions to volunteer

    Directory of Open Access Journals (Sweden)

    Lauren S. Carroll

    2011-10-01

    Full Text Available Excess choice has previously been shown to have detrimental effects on decisions about consumer products. As the number of options increases, people are more likely to put off making an active choice (i.e., defer and show less satisfaction with any purchase actually made. We extend this line of enquiry to choosing a charitable organisation to volunteer for. The issue is important because the number of voluntary organisations is enormous and the impact of such a decision may be greater than for consumer decisions in terms of time commitment and benefits to the volunteer and society. Study 1 asked students to examine a real volunteering website and record how many organisations they considered, decision difficulty and whether or not they would like to sign up for a chosen organisation or prefer to defer a decision. Study 2 presented either a relatively small (10 or large (30 choice set of hypothetical organisations and measured deferment likelihood and decision difficulty. In both studies the more options considered, the greater the likelihood to defer. This effect was mediated by decision difficulty. This research is the first to find that detrimental effects of excess choice extend to volunteering. Implications for volunteer recruitment are discussed.

    Full Text Available Abstract Objective To evaluate the feasibility of a large immediate versus deferred antiretroviral therapy (ART study in children. Methods We conducted an open-label pilot randomized clinical trial study in 43 Thai children with CD4 15 to 24% of starting generic AZT/3TC/NVP immediately (Arm 1 or deferring until CD4 Results Recruitment took 15 months. Twenty-six of 69 (37.7% were not eligible due mainly to low CD4%. Twenty four and 19 were randomized to arms 1 and 2 respectively. All accepted the randomized arm; however, 3 in arm 1 stopped ART and 1 in arm 2 refused to start ART. Ten/19 (53% in arm 2 started ART. At baseline, median age was 4.8 yrs, CDC A:B were 36:7, median CD4 was 19% and viral load was 4.8 log. All in arm 1 and 17/19 in arm 2 completed the study (median of 134 weeks. No one had AIDS or death. Four in immediate arm had tuberculosis. Once started on ART, deferred arm children achieved similar CD4 and viral load response as the immediate arm. Adverse events were similar between arms. The deferred arm had a 26% ART saving. Conclusion Almost 40% of children were not eligible due mainly to low CD4% but adherence to randomized treatment and retention in trial were excellent. A larger study to evaluate when to start ART is feasible.

    XIAO Jian-wu; YIN Shao-hua; QIN Cheng-lin

    2006-01-01

    The constant elasticity of variance(CEV) model was constructed to study a defined contribution pension plan where benefits were paid by annuity. It also presents the process that the Legendre transform and dual theory can be applied to find an optimal investment policy during a participant's whole life in the pension plan. Finally, two explicit solutions to exponential utility function in the two different periods (before and after retirement) are revealed. Hence, the optimal investment strategies in the two periods are obtained.

    2008-01-01

    We develop a theory for valuing non-diversifiable mortality risk in an incomplete market. We do this by assuming that the company issuing a mortality-contingent claim requires compensation for this risk in the form of a pre-specified instantaneous Sharpe ratio. We apply our method to value life annuities. One result of our paper is that the value of the life annuity is {\\it identical} to the upper good deal bound of Cochrane and Sa\\'{a}-Requejo (2000) and of Bj\\"{o}rk and Slinko (2006) applied to our setting. A second result of our paper is that the value per contract solves a {\\it linear} partial differential equation as the number of contracts approaches infinity. One can represent the limiting value as an expectation with respect to an equivalent martingale measure (as in Blanchet-Scalliet, El Karoui, and Martellini (2005)), and from this representation, one can interpret the instantaneous Sharpe ratio as an annuity market's price of mortality risk.

  16. Development of underground-mine cost-estimating equations. [Dependence of initial capital cost, deferred capital cost and annual operating cost on region, annual mine output and seam depth

    Energy Technology Data Exchange (ETDEWEB)

    1981-03-06

    Table 3.3 summarizes the initial capital, deferred capital, and operating costs (in millions of 1980 dollars) for the four regionally-based underground model mines. The initial capital is divided into two components, fixed and variable. The fixed component is just the investment cost for surface facilities, which is assumed to be independent of mine size. The rest of the initial capital cost is associated with production (primarily face-related) and is assumed to vary linearly with mine size (i.e., annual output). There exists a concern that deferred capital costs will change due to entry mode. However, the installations concerned primarily with this point are depreciated off over the mine life and are not targeted for replacement. Therefore, deferred capital costs will not change significantly with entry mode changes or seam depth. In conclusion, it is our feeling that, within the resources of this project, development of cost adjustment factors relating productivity to various supply regions and seam heights is not practical. Assuming that productivity and, therefore, cost is independent of seam height will introduce errors into the system; however, their extent should be minimized by the incorporation of multiple model mines into the RAMC. Lastly, the relationship presented in this memorandum for depth of cover should be used in the RAMC.

  2. Semi-implicit spectral deferred correction methods for ordinary differential equations

    Energy Technology Data Exchange (ETDEWEB)

    Minion, Michael L.

    2002-10-06

    A semi-implicit formulation of the method of spectral deferred corrections (SISDC) for ordinary differential equations with both stiff and non-stiff terms is presented. Several modifications and variations to the original spectral deferred corrections method by Dutt, Greengard, and Rokhlin concerning the choice of integration points and the form of the correction iteration are presented. The stability and accuracy of the resulting ODE methods are explored analytically and numerically. The SISDC methods are intended to be combined with the method of lines approach to yield a flexible framework for creating higher-order semi-implicit methods for partial differential equations. A discussion and numerical examples of the SISDC method applied to advection-diffusion type equations are included. The results suggest that higher-order SISDC methods are more efficient than semi-implicit Runge-Kutta methods for moderately stiff problems in terms of accuracy per function evaluation.

    2015-01-01

    Given the increasing use of stock options in executive compensation, we examine how taxes influence the choice of compensation and document that income deferral is an important margin of adjustment in response to tax rate changes. To account for this option in the empirical analysis, we explore deferral by estimating how executives’ choice of compensation between current and deferred income depends on changes in tax policy. Our empirical results suggest a significant impact of taxes on the co...

  8. Pricing Equity-Indexed Annuities under Stochastic Interest Rates Using Copulas

    Directory of Open Access Journals (Sweden)

    Patrice Gaillardetz

    2010-01-01

    Full Text Available We develop a consistent evaluation approach for equity-linked insurance products under stochastic interest rates. This pricing approach requires that the premium information of standard insurance products is given exogenously. In order to evaluate equity-linked products, we derive three martingale probability measures that reproduce the information from standard insurance products, interest rates, and equity index. These risk adjusted martingale probability measures are determined using copula theory and evolve with the stochastic interest rate process. A detailed numerical analysis is performed for existing equity-indexed annuities in the North American market.

    2012-09-01

    To fulfill Food and Drug Administration and Department of Health and Human Services emergency care research informed consent requirements, our burn center planned and executed a deferred consent strategy gaining Institutional Review Board (IRB) approval to proceed with the clinical study. These federal regulations dictate public disclosure and community consultation unique to acute care research. Our regional burn center developed and implemented a deferred consent public notification and community consultation paradigm appropriate for a burn study. Published accounts of deferred consent strategies focus on acute care resuscitation practices. We adapted those strategies to design and conduct a comprehensive public notification/community consultation plan to satisfy deferred consent requirements for burn center research. To implement a robust media campaign we engaged the hospital's public relations department, distributed media materials, recruited hospital staff for speaking engagements, enlisted community volunteers, and developed initiatives to inform "hard-to-reach" populations. The hospital's IRB determined we fulfilled our obligation to notify the defined community. Our communication strategy should provide a paradigm other burn centers may appropriate and adapt when planning and executing a deferred consent initiative. Copyright © 2012 Elsevier Ltd and ISBI.

  16. Great apes can defer exchange: a replication with different results suggesting future oriented behavior.

    Science.gov (United States)

    Osvath, Mathias; Persson, Tomas

    2013-01-01

    The topic of cognitive foresight in non-human animals has received considerable attention in the last decade. The main questions concern whether the animals can prepare for upcoming situations which are, to various degrees, contextually or sensorially detached from the situation in which the preparations are made. Studies on great apes have focused on tool-related tasks, e.g., the ability to select a tool which is functional only in the future. Dufour and Sterck (2008), however, investigated whether chimpanzees were also able to prepare for a future exchange with a human: an object exchanged for a food item. The study included extensive training on the exchangeable item, which is traditionally not compatible with methods for studying planning abilities, as associative learning cannot be precluded. Nevertheless, despite this training, the chimpanzees could not solve the deferred exchange task. Given that great apes can plan for tool use, these results are puzzling. In addition, claims that great ape foresight is highly limited has been based on this study (Suddendorf and Corballis, 2010). Here we partly replicated Dufour and Sterck's study to discern whether temporally deferred and spatially displaced exchange tasks are beyond the capabilities of great apes. In addition to chimpanzees we tested orangutans. One condition followed the one used by Dufour and Sterck, in which the exchange items, functional only in the future, are placed at a location that freely allows for selections by the subjects. In order to test the possibility that the choice set-up could explain the negative results in Dufour and Sterck's study, our second condition followed a method used in the planning study by Osvath and Osvath (2008), where the subjects make a forced one-item-choice from a tray. We found that it is within the capabilities of chimpanzees and orangutans to perform deferred exchange in both conditions.

    2009-01-01

    BACKGROUND Deferral for travel to malaria-endemic areas excludes many blood donors in the United States. Most transfusion-transmitted malaria is associated with lengthy residence in malaria-endemic areas rather than routine travel. This study compares the impact of existing deferral requirements to the risk that a presenting donor with malaria travel history harbors malaria parasites under current and hypothetical alternate regulations. STUDY DESIGN AND METHODS Deferred donors from six blood centers were sampled to estimate a national cohort of donors deferred annually for malaria travel to different geographic regions. Risk for malaria infection following travel to each region, and distribution of incubation periods for each malaria species were estimated for U.S. travelers. Region-specific travel risks were used to estimate the risk that a presenting blood donor with malaria travel might asymptomatically harbor malaria parasites at different intervals following return to the United States. RESULTS Travel to Africa presents risk for malaria infection >1000 times that of travel to malaria-endemic parts of Mexico, yet Mexico accounts for >10 times as many deferred donors. Shortening the deferral period from 12 to 3 months for travelers to Mexico increases the risk of collecting a contaminated unit by only 1 unit per 57 years (sensitivity analysis, 1 every 29 - 114 years), at annual gain of >56,000 donations. CONCLUSION This study provides the first systematic appraisal of the U.S. requirements for donor qualification regarding travel to malarial areas. Consideration should be given to relaxing the guidelines for travel to very low-risk areas such as Mexico. PMID:19903290

    Strid, Karin; Heimann, Mikael; Tjus, Tomas

    2013-02-01

    This study investigates spontaneous pretend play during a parent-child free play observation, and deferred imitation observed in an experimental setting in speaking and non-speaking children with autism in comparison to children with typical development. Both groups of children with autism showed a reduced level of deferred imitation compared to the typically developing group, but only the non-speaking children with autism spent significantly less time in pretend play compared to children with typical development. Deferred imitation was related to parents' verbal interaction in both groups. An analysis of the parent-child interaction revealed that parents of children with autism used less synchronized comments compared to parents of typically developing children. Parents of the speaking group with autism used more synchronized than unsynchronized comments, while parents of the non-speaking group used the same amount of synchronized and unsynchronized comments. These findings are discussed in terms of how the developmental level affects behavior and interaction in autism.

    Data on the clinical outcomes in deferred coronary lesions according to functional severity have been limited. This study evaluated the clinical outcomes of deferred lesions according to fractional flow reserve (FFR) grade using Korean FFR registry data. Among 1,294 patients and 1,628 lesions in Korean FFR registry, 665 patients with 781 deferred lesions were included in this study. All participants were consecutively categorized into 4 groups according to FFR; group 1: ≥ 0.96 (n = 56), group 2: 0.86-0.95 (n = 330), group 3: 0.81-0.85 (n = 170), and group 4: ≤ 0.80 (n = 99). Primary endpoint was major adverse cardiac events (MACE), a composite of all-cause death, myocardial infarction, and target vessel revascularization. The median follow-up period was 2.1 years. During follow-up, the incidence of MACE in groups 1-4 was 1.8%, 7.6%, 8.8%, and 13.1%, respectively. Compared to group 1, the cumulative rate by Kaplan-Meier analysis of MACE was not different for groups 2 and 3. However, group 4 had higher cumulative rate of MACE compared to group 1 (log-rank P = 0.013). In the multivariate Cox hazard models, only FFR (hazard ratio [HR], 0.95; P = 0.005) was independently associated with MACE among all participants. In contrast, previous history of percutaneous coronary intervention (HR, 2.37; P = 0.023) and diagnosis of acute coronary syndrome (ACS) (HR, 2.35; P = 0.015), but not FFR, were independent predictors for MACE in subjects with non-ischemic (FFR ≥ 0.81) deferred coronary lesions. Compared to subjects with ischemic deferred lesions, clinical outcomes in subjects with non-ischemic deferred lesions according to functional severity are favorable. However, longer-term follow-up may be necessary.

    2003-01-01

    Subsequent to the modifications to the Rules and Regulations of the Pension Fund allowing members of the personnel having five years of affiliation to the Fund to opt for a deferred retirement pension, the Organization wishes to recall the rules relating to the affiliation of those beneficiaries to the CERN Health Insurance Scheme (CHIS). In accordance with Articles III 2.02 and VIII 4.02 of the CHIS Rules, beneficiaries of a deferred retirement pension can only be Members of the CHIS as CERN pensioners if they applied to remain Members of the Scheme upon termination of their compulsory membership as a member of the personnel and if their membership has been uninterrupted up to the moment they become CERN pensioners. The applicable contribution for this intermediate period is indicated in Articles III 5.03 and X 1.02 of the CHIS Rules. The amount is revised annually, and is set at 936 CHF/ month for 2003.

  4. Undocumented students pursuing medical education: The implications of deferred action for childhood arrivals (DACA).

    Science.gov (United States)

    Balderas-Medina Anaya, Yohualli; del Rosario, Mithi; Doyle, Lawrence Hy; Hayes-Bautista, David E

    2014-12-01

    There are about 1.8 million young immigrants in the United States who came or were brought to the country without documentation before the age of 16. These youth have been raised and educated in the United States and have aspirations and educational achievements similar to those of their native-born peers. However, their undocumented status has hindered their pursuit of higher education, especially in medical and other graduate health sciences. Under a new discretionary policy, Deferred Action for Childhood Arrivals (DACA), many of these young immigrants are eligible to receive permission to reside and work in the United States. DACA defers deportation of eligible, undocumented youth and grants lawful presence in the United States, work permits, Social Security numbers, and, in most states, driver's licenses. These privileges have diminished the barriers undocumented students traditionally have faced in obtaining higher education, specifically in pursuing medicine. With the advent of DACA, students are slowly matriculating into U.S. medical schools and residencies. However, this applicant pool remains largely untapped. In the face of a physician shortage and the implementation of the Affordable Care Act, an increase in matriculation of qualified undocumented students would be greatly beneficial. This Perspective is intended to begin discussion within the academic medicine community of the implications of DACA in reducing barriers for the selection and matriculation of undocumented medical students and residents. Moreover, this Perspective is a call to peers in the medical community to support undocumented students seeking access to medical school, residency, and other health professions.

  5. Pulmonary effects of immediate versus deferred antiretroviral therapy in HIV-positive individuals

    2016-01-01

    BACKGROUND: Observational data have been conflicted regarding the potential role of HIV antiretroviral therapy (ART) as a causative factor for, or protective factor against, COPD. We therefore aimed to investigate the effect of immediate versus deferred ART on decline in lung function in HIV...... were not masked to the treatment group assignment; however, the assessors who reviewed the outcomes were masked to the treatment group. The primary outcome was the annual rate of decline in lung function, expressed as the FEV1 slope in mL/year; spirometry was done annually during follow-up for up to 5...... and 28% were current smokers. Median follow-up time was 2·0 years (IQR 1·9-3·0). We noted no differences in FEV1 slopes between the immediate and deferred ART groups either in smokers (difference of -3·3 mL/year, 95% CI -38·8 to 32·2; p=0·86) or in non-smokers (difference of -5·6 mL/year, -29·4 to 18...

  6. Why birds with deferred sexual maturity are sedentary on islands: a systematic review.

    Directory of Open Access Journals (Sweden)

    Miguel Ferrer

    Full Text Available BACKGROUND: Island faunas have played central roles in the development of evolutionary biology and ecology. Birds are among the most studied organisms on islands, in part because of their dispersal powers linked to migration. Even so, we lack of information about differences in the movement ecology of island versus mainland populations of birds. METHODOLOGY/PRINCIPAL FINDINGS: Here we present a new general pattern indicating that large birds with deferred sexual maturity are sedentary on islands, and that they become so even when they are migratory on the mainland. Density-dependent variation in the age at first breeding affects the survivorship of insular populations and this, in turn, affects the movement ecology of large birds. Because density-dependent variation in the age of first breeding is critical to the long-term survival of small isolated populations of long-lived species, migratory forms can successfully colonize islands only if they become sedentary once there. Analyses of the movement ecology of continental and insular populations of 314 species of raptors, 113 species of Ciconiiformes and 136 species of passerines, along with individual-based population simulations confirm this prediction. CONCLUSIONS: This finding has several consequences for speciation, colonization and survival of small isolated population of species with deferred sexual maturity.

  7. Deference and Diffèrance: Judicial Review and the Perfect Gift

    Directory of Open Access Journals (Sweden)

    J De Ville

    2006-01-01

    Full Text Available The highest courts in both Canada and South Africa have expressed themselves in favour of an approach of deference as respect in the review of administrative action. The notion of deference as respect derives from the thinking of David Dyzenhaus, who has developed a theory of democracy in support of this approach to judicial review. Dyzenhaus’ model of review attempts to steer clear from the problems he associates particularly with positivism and liberalism. Dyzenhaus’ model of review furthermore attempts to allow space for the administration to play a significant role in giving effect to democratic values, on the understanding that all such decisions need to be reasonably justifiable. In this article the views of Dyzenhaus are contrasted with those of Jacques Derrida, especially insofar as the latter has reflected on the relation between law and justice, as well as concepts such as the gift and democracy. The argument developed in this article is that Dyzenhaus’ model of review, despite its many positive features, needs to be rethought with reference to the perfect gift, unconditional justice and democracy to come. Such a rethinking is required because of the limited conception of justice – as simply ‘our’ justice – in Dyzenhaus’ model.

    Full Text Available There has always been and will be a relationship between accounting and taxation, and the ongoing discussions are related to intensity, interrelation and generation of reciprocal effects. Profit is the "wealth" achieved by the economic entity, the share of shareholders after paying the income tax, where applicable, which makes the profit have a major influence on the method of determination and thus of the accounting treatment incurred by the income tax depending on the accounting cultures in dispute for supremacy, namely the European accounting culture and the Anglo-Saxon accounting culture. As the users of information in the financial statements seek to assess the performance and profitability of the company in general and, academically, the income tax is the only element raising debates on the relationship between accounting and taxation, we deemed it useful to conduct a study on the accounting – taxation report in terms of deferred taxes related to assets revaluation. The record of deferred tax amount for each type of temporary difference results in elimination of tax effects from accounting, with the aim of revealing the real earnings of the economic entity and not its fiscal side, all of which is a step in disconnecting the taxation accounting

    Full Text Available Abstract Background The optimal stage for initiating antiretroviral therapies in HIV-1 bearing patients is still a matter of debate. Methods We present computer simulations of HIV-1 infection aimed at identifying the pro et contra of immediate as compared to deferred Highly Active Antiretroviral Therapy (HAART. Results Our simulations highlight that a prompt specific CD8+ cytotoxic T lymphocytes response is detected when therapy is delayed. Compared to very early initiation of HAART, in deferred treated patients CD8+ T cells manage to mediate the decline of viremia in a shorter time and, at interruption of therapy, the virus experiences a stronger immune pressure. We also observe, however, that the immunological effects of the therapy fade with time in both therapeutic regimens. Thus, within one year from discontinuation, viral burden recovers to the value at which it would level off in the absence of therapy. In summary, simulations show that immediate therapy does not prolong the disease-free period and does not confer a survival benefit when compared to treatment started during the chronic infection phase. Conclusion Our conclusion is that, since there is no therapy to date that guarantees life-long protection, deferral of therapy should be preferred in order to minimize the risk of adverse effects, the occurrence of drug resistances and the costs of treatment.

    Immediate delivery of the preterm fetus with suspected compromise may decrease the risk of damage due to intrauterine hypoxia. However, it may also increase the risks of prematurity. To assess the effects of immediate versus deferred delivery of preterm babies with suspected fetal compromise on neonatal, maternal and long-term outcomes. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2016) and reference lists of retrieved studies. Randomised trials comparing a policy of immediate delivery with deferred delivery or expectant management in preterm fetuses with suspected in utero compromise. Quasi-randomised trials and trials employing a cluster-randomised design were eligible for inclusion but none were identified. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. We included one trial of 548 women (588 babies) in the review. Women with pregnancies between 24 and 36 weeks' gestation took part. The study took place in 13 European countries, between 1993 and 2001. The difference in the median randomisation to delivery interval between immediate delivery and deferred delivery was four days (median: 0.9 (inter-quartile range (IQR) 0.4 to 1.3) days for immediate delivery, median: 4.9 (IQR 2.0 to 10.8) days in the delay group).There was no clear difference in the primary outcomes of extended perinatal mortality (risk ratio (RR) 1.17, 95% confidence interval (CI) 0.67 to 2.04, one trial, 587 babies, moderate-quality evidence) or the composite outcome of death or disability at or after two years of age (RR 1.22, 95% CI 0.85 to 1.75, one trial, 573 babies, moderate-quality evidence) with immediate delivery compared to deferred delivery. The results for these outcomes are consistent with both appreciable benefit and harm. More babies in the immediate delivery group were ventilated for more than 24 hours (RR 1.54, 95% CI 1.20 to 1.97, one trial, 576 babies). There

    Full Text Available Abstract Background Voluntary participation of a subject in research respects a subject's rights, strengthens its ethical conduct, and is formalized by the informed consent process. Clinical trials of life-saving interventions for medical emergencies often necessitate enrolment of patients where prior written individual informed consent is impossible. Although there are regulations and guidelines on protecting subjects in emergency research, these have been criticised for being limited and unnecessarily restrictive. Across Europe and the United States stringent regulations have resulted in a substantial decline of clinical trials involving emergency interventions. Methods We are conducting a trial of fluid resuscitation in children with hypovolaemic shock in six hospitals across three malaria-endemic African countries. The design is pragmatic as children are enrolled on clinical criteria alone and is being conducted in hospitals with facilities typical of many district hospitals across Africa. The trial aims to inform strategy for managing children with febrile illness and features of shock. In order to develop appropriate consent processes for the trial, we conducted a narrative review of current international recommendations for emergency consent. Results Practical or specific guidance was generally sparse or confusing with few examples in the literature to direct our informed consent process. For a sub-group of children who were critically sick or where parents themselves were otherwise too distressed to consider prior written consent, we opted for a modified form of deferred consent. This included verbal assent from guardians at the point of enrolment, with full written consent obtained after stabilising the child. For children who died prior to full written consent, ethical permission was received to waiver full consent. Conclusions In light of the controversy around guidance and regulations in this area we report how and why we have used a

    2014-01-01

    Full Text Available Defined contribution and annuity contract are merged into one pension plan to study both accumulation phase and distribution phase, which results in such effects that both phases before and after retirement being “defined”. Under the Heston’s stochastic volatility model, this paper focuses on mean-variance insurers with the return of premiums clauses to study the optimal time-consistent investment strategy for the DC pension merged with an annuity contract. Both accumulation phase before retirement and distribution phase after retirement are studied. In the time-consistent framework, the extended Hamilton-Jacobi-Bellman equations associated with the optimization problem are established. Applying stochastic optimal control technique, the time-consistent explicit solutions of the optimal strategies and the efficient frontiers are obtained. In addition, numerical analysis illustrates our results and also deepens our knowledge or understanding of the research results.

  2. Deferred Action: Theoretical model of process architecture design for emergent business processes

    Directory of Open Access Journals (Sweden)

    Patel, N.V.

    2007-01-01

    Full Text Available E-Business modelling and ebusiness systems development assumes fixed company resources, structures, and business processes. Empirical and theoretical evidence suggests that company resources and structures are emergent rather than fixed. Planning business activity in emergent contexts requires flexible ebusiness models based on better management theories and models . This paper builds and proposes a theoretical model of ebusiness systems capable of catering for emergent factors that affect business processes. Drawing on development of theories of the ‘action and design’class the Theory of Deferred Action is invoked as the base theory for the theoretical model. A theoretical model of flexible process architecture is presented by identifying its core components and their relationships, and then illustrated with exemplar flexible process architectures capable of responding to emergent factors. Managerial implications of the model are considered and the model’s generic applicability is discussed.

    Malaria was expected to be a major problem during blood donation in Turkey due to existence of malaria cases in southeastern region of Turkey. The present study aimed for the first time, to investigate malaria in "donors deferred for malaria risk" and to determine the regional rates of malaria deferral in Turkey. Blood samples were collected from several Blood Banks of southeastern provinces where local malaria cases still exist and from Blood Bank of Ege University Medical School (EUMS) located in western Turkey where malaria is eradicated decades ago. Plasmodium spp. and specific antibodies were investigated by stained smears, antigen detection, PCR and ELISA. Among the donors deferred for malaria risk, Plasmodium spp. were not detected by microscopy, PCR or antigen detection. Seroprevalances were 2% and 3.92% in western and southeastern regions, respectively. Rate of donor deferral for malaria risk was 0.9% in EUMS and deferrals were exclusively because of travel to southeastern Turkey. In southeastern provinces, deferrals were mainly due to malaria like fever history. The present study first time assessed regional rates of donor deferral due to malaria risk in Turkey. Previously, malaria was expected to be a major problem during blood donation in Turkey due to existence of malaria cases in southeastern region of Turkey. The results of the study showed that 97% of the deferrals were unnecessary. In conclusion, to reduce unnecessary donor deferrals in Turkey, in addition to comprehensive questioning for malaria history, the usage of a malaria antibody screening method should be initiated prior to deferral decision.

    Background More than 66,000 blood donors are deferred annually in the U.S. due to travel to malaria-endemic areas of Mexico. Mexico accounts for the largest share of malaria travel deferrals, yet it has extremely low risk for malaria transmission throughout most of its national territory, suggesting a suboptimal balance between blood safety and availability. This study sought to determine whether donor deferral requirements might be relaxed for parts of Mexico without compromising blood safety. Study Design and Methods Travel destination was recorded from a representative sample of presenting blood donors deferred for malaria travel from six blood centers during 2006. We imputed to these donors reporting Mexican travel a risk for acquiring malaria equivalent to Mexican residents in the destination location, adjusted for length of stay. We extrapolated these results to the overall U.S. blood donor population. Results Risk for malaria in Mexico varies significantly across endemic areas and is greatest in areas infrequently visited by study donors. Over 70% of blood donor deferrals were triggered by travel to the state of Quintana Roo on the Yucatán Peninsula, an area of very low malaria transmission. Eliminating the travel deferral requirement for all areas except the state of Oaxaca might result in the recovery of almost 65,000 blood donors annually at risk of approximately one contaminated unit collected every 20 years. Conclusion Deferral requirements should be relaxed for presenting donors who travelled to areas within Mexico that confer exceptionally small risks for malaria, such as Quintana Roo. PMID:21564102

    2014-02-01

    Full Text Available The aim this work was to evaluate the morphogenic and structural characteristics of Brachiaria decumbens pastures to determine the most suitable nitrogen fertilization strategies, for pastures deferred for a period of 95 days. Four strategies of fertilization at the beginning and end of the summer (0-0, 100- 0, 50-50, 0-100 kg ha-1 N were studied, respectively, with four replications. The strategy of 100 kg ha-1 N applied at the end of the summer (0-100, followed the parceling strategy at the beginning and end of the summer (50-50 favored higher rates of leaf appearance and lower values of phyllochron. Greater rate of leaf elongation was observed for 0-100 strategy, resulting in 40% increase compared to pastures that were not fertilized. However, there was no effect of fertilization strategies on stem elongation rate, registering an average of 0.28 cm.dia-1. There was a higher blade:stem ratio for the stratum A (40 cm above the soil in all treatments, observing higher blade:stem ratio for strategies 0-100 and 50-50, at this stratum. There was no effect for the total number of leaves and final leaf length. However, greater stem lengths were observed in pastures with 0-100 fertilizer strategy, followed by the 50-50 strategy. The strategy of applying 100 kg ha-1 at the end of summer, followed by the strategy of 50 kg ha-1 nitrogen divided at the beginning and end of summer, promote greater influence on the morphogenic and structural traits, in pastures deferred for 95 days.

    Using the China Matching Data of Employer-Employee Tracking Survey of 2013,We exam-ine empirically the impacts of enterprise annuity on job search behavior and tenure of employees.As empirical results indicate,the implementation of enterprise annuity deters job search behavior only for women aged 30 above.Additionally,a positive effect of pension coverage on the duration of tenure for both men and women is found,which is significantly more pronounced in large-scaled firms.Firm rep-utation effect is exploited to explain the differential impact of pension coverage on these two dependent variables.According to our empirical results,the implementation of enterprise annuity does play a role in the Chinas micro labor market outcomes.%基于2013年中国雇主—雇员匹配数据,关于企业年金对工作搜寻和任期长短的影响的实证研究结果显示,企业年金的实施对我国的微观劳动力市场产生了相关的经济效应。具体表现为:企业年金作为二分变量对30岁以上女性的工作搜寻行为有显著的负向效应,而对男性工作搜寻行为的影响并不显著;企业年金对员工任期有显著的延长效应,且在规模较大的公司中更为显著。企业声誉效应可以解释企业年金对这两个因变量的差异化影响。

  8. Means And Ends In City Of Arlington v. FCC: Ignoring The Lawyer's Craft to Reshape the Scope of Chevron Deference

    Directory of Open Access Journals (Sweden)

    Michael P. Healy

    2015-07-01

    Full Text Available In last year’s term, the United States Supreme Court considered the question of the scope of Chevron deference in City of Arlington v. FCC. This article discusses how the decision is an example of the work of an activist Court. The case should have been resolved by a straight forward determination under the analysis of United States v. Mead that Chevron deference simply did not apply to the Federal Communications Commission’s (“FCC” legal determination. The Court ignored this restrained approach to the case and instead addressed the question the Justices desired to decide: the reach of Chevron deference. The article discusses and criticizes the approach of Justice Scalia writing for the majority and of Chief Justice Roberts writing for three dissenting Justices.Practitioners and scholars of administrative law can only be confused by the Court’s willingness to apply Chevron in City of Arlington, given the informal administrative action being reviewed and the fact that neither reviewing court actually applied each of the two parts of the Mead test. The Court’s flawed administrative law analysis results from the activist concerns of Justice Scalia and Chief Justice Roberts. Justice Scalia uses the case as a vehicle to undermine Mead, a decision that Justice Scalia loathes. Chief Justice Roberts uses the case as a vehicle to advocate for less judicial deference and less law defining power for increasingly powerful agencies. Neither member of the Court allowed the applicable rules of contemporary administrative law to hinder his efforts to achieve his broader goals. Administrative law would have been better served if a properly restrained Court had considered and applied the previously determined rules for judicial review of administrative agencies.

    Minjie Gao

    Full Text Available Whether patients with smoldering multiple myeloma (SMM needed to receive early interventional treatment remains controversial. Herein, we conducted a meta-analysis comparing the efficacy and safety of early treatment over deferred treatment for patients with SMM.MEDLINE and Cochrane Library were searched to May 2014 for randomized controlled trials (RCTs that assessed the effect of early treatment over deferred treatment. Primary outcome measure was mortality, and secondary outcome measures were progression, response rate, and adverse events.Overall, 5 trials including 449 patients were identified. There was a markedly reduced risk of disease progression with early treatment (Odds Ratio [OR] = 0.13, 95% confidence interval [CI] = 0.07 to 0.24. There were no significant differences in mortality and response rate (OR = 0.85, 95% CI = 0.45 to 1.60, and OR = 0.63, 95% CI = 0.32 to 1.23, respectively. More patients in the early treatment arm experienced gastrointestinal toxicities (OR = 10.02, 95%CI = 4.32 to 23.23, constipation (OR = 8.58, 95%CI = 3.20 to 23.00 and fatigue or asthenia (OR = 2.72, 95%CI = 1.30 to 5.67. No significant differences were seen with the development of acute leukemia (OR = 2.80, 95%CI = 0.42 to 18.81, hematologic cancer (OR = 2.07, 95%CI = 0.43 to 10.01, second primary tumors (OR = 3.45, 95%CI = 0.81 to 14.68, nor vertebral compression (OR = 0.18, 95%CI = 0.02 to 1.59.Early treatment delayed disease progression but increased the risk of gastrointestinal toxicities, constipation and fatigue or asthenia. The differences on vertebral compression, acute leukemia, hematological cancer and second primary tumors were not statistically significant. Based on the current evidence, early treatment didn't significantly affect mortality and response rate. However, further much larger trials were needed to provide more evidence.

These conclusions can give a good reference for the construction of the thermal blooming test system of laser system. Contrasted with the thermal blooming scaling parameters of the Bradley-Hermann distortion number ND and Fresnel number NF, which were derived based on the change of far field beam intensity distortion, the scaling parameters of pipe flow thermal blooming deduced from the optical path deference variation are very suitable for the optical system with short laser propagation distance, large Fresnel number and obviously changed optical path deference.

    In many of the social security system reforms, the enterprise annuity (supplementary pension insurance) system is very closely related to Human Resource Management and is also for the Government to guide the enterprises to voluntarily decide to do the social security activities for their employees. According to the role of practice in the management of enterprise annuity, this study of motivation theory and the theory of annuity proposed that enterprise annuity could influence the loyalty of employees and had a certain influence on staff mobility and had a significant effect on the incentive effectiveness because of the different annuity ratio. Empirical research shows that the normative annuity operation has significant incentive effectiveness.%在社会保障制度的多项改革中,企业年金(补充养老保险金)制度与人力资源管理密切相关,也是政府引导企业自愿决定进行的职工保障活动.本研究从研究激励理论和年金理论入手,根据激励在管理实践中的作用提出了企业年金对员工忠诚度有一定影响;对员工流动性有一定影响;年金比例不同对激励效用有明显影响的理论观点.实证调查显示,规范性操作的企业年金激励效用非常显著.

    2015-01-01

    Full Text Available With the introduction of Solvency II a consistent market approach to the valuation of insurance assets and liabilities is required. For the best estimate of life annuity provisions one should estimate the longevity risk of the insured population in Slovenia. In this paper the current minimum standard in Slovenia for calculating pension annuities is tested using the Lee-Carter model. In particular, the mortality of the Slovenian population is projected using the best fit from the stochastic mortality projections method. The projected mortality statistics are then corrected with the selection effect and compared with the current minimum standard.

    Objective:To compare the efficacy of direct stent implantation surgery and deferred stent implantation surgery for patients with ST-segment elevation myocardial infarction after PCT thrombus aspiration surgery. Method:A total of 74 cases with STEMI were selected, who had been given PCT thrombus aspiration surgery treatment, and were randomly divided into direct group and deferred group (n=37). Patients in direct group were given direct stent implantation surgery after PCT thrombus aspiration surgery treatment. Patients in deferred group were given deferred stent implantation surgery 14 d later after anticoagulant and anti-platelet treatment. Heart structure and function, stent release characteristics and adverse reactions) were compared 6 months after the surgery. Results:Two hours after surgery, ST segment drop amplitude in deferred group was significantly higher than that in direct group (P<0.05);TIMI frame number was obvious and no reflow/slow blood flow occurrence ratio was significantly lower than that in direct group (P<0.05);implantation stent number and stent length in deferred group were significantly less than that in direct group (P<0.05);the release characteristic indexes of implantation stent in deferred group:stent diameter and stent expansion pressure were significantly higher than that in direct group (P<0.05);6 months after surgery, LVEF improvement in deferred group was significantly higher than that in direct group (P<0.05), while LVEDD、LVEDV ventricular remodeling was significantly lower than that in direct group (P<0.05);The total adverse event occurrence rate in deferred group was 5.4%, which was significantly lower than that in direct group (18.9%) (P<0.05). Conclusions:The deferred stent implantation surgery after PCI thrombus aspiration surgery could obviously reduce the occurrence rate of no reflow/slow blood flow, obviously improve the heart function and myocardial perfusion, reduce the usage amount of stent, reduce the occurrence of

    Full Text Available Surgical resection for well-selected patients with refractory epilepsy provides seizure freedom approximately two-thirds of the time. Despite this, many good candidates for surgery, after a presurgical workup, ultimately do not consent to a procedure.

    To assess the safety and efficacy of deferred versus complete revascularization using a fractional flow reserve (FFR)-guided strategy in patients with diabetes mellitus (DM), we analyzed all DM patients who underwent FFR-guided revascularization from January 1, 2010, to December 12, 2013. Patients were divided into 2 groups: those with ≥1 remaining FFR-negative (>0.80) medically treated lesions [FFR(-)MT] and those with only FFR-positive lesions (≤0.80) who underwent complete revascularization [FFR(+)CR] and were followed until July 1, 2015. The primary end point was the incidence of major adverse cardiovascular events (MACE), a composite of death, myocardial infarction (MI), target lesion (FFR assessed) revascularization, and rehospitalization for acute coronary syndrome. A total of 294 patients, 205 (69.7%) versus 89 (30.3%) in FFR(-)MT and FFR(+)CR, respectively, were analyzed. At a mean follow-up of 32.6 ± 18.1 months, FFR(-)MT was associated with higher MACE rate 44.0% versus 26.6% (log-rank p = 0.02, Cox regression-adjusted hazard ratio [HR] 2.01, 95% confidence interval [CI] 1.21 to 3.33, p required to guide our treatment strategy in these patients with high-risk, fast-progressing atherosclerosis.

    2015-01-01

    A first-person-shooter video game was adapted for the study of choice between smaller sooner and larger later outcomes to compare the behavioral patterns produced by deferred gratification (DG) and delay discounting (DD) tasks. Participants played a game in which they could either fire their weapon sooner and do a small amount of damage or wait a few seconds to fire their weapon and do a larger amount of damage. For the DD task, a failure to fire within one second committed the player to waiting for the larger later outcome thus removing the opportunity to defect during the delay that is present in the DG task. The incentive structure changed multiple times during game play so that at times the optimal decision was to choose the smaller sooner outcome whereas at other times the optimal decision was to wait for the larger later outcome. Players assigned to the DD task showed a greater tendency to wait and lower sensitivity to the changing incentives.

    Surgical resection for well-selected patients with refractory epilepsy provides seizure freedom approximately two-thirds of the time. Despite this, many good candidates for surgery, after a presurgical workup, ultimately do not consent to a procedure. The reasons why patients decline potentially effective surgery are not completely understood. We explored the socio cultural, medical, personal, and psychological differences between candidates who chose (n = 23) and those who declined surgical intervention (n = 9). We created a novel questionnaire addressing a range of possible factors important in patient decision making. We found that patients who declined surgery were less bothered by their epilepsy (despite comparable severity), more anxious about surgery, and less likely to listen to their doctors (and others) and had more comorbid psychiatric disease.

  1. ‘Humblewise’: Deference and Complaint in the Court of Requests

    2015-03-01

    Full Text Available When servants, laborers, and apprentices sued their masters for back wages or mistreatment in the Court of Requests they took advantage of the court’s doctrine of equity. Since these plaintiffs often lacked the strict written proofs required by common law, or were bound by unfair written contracts, they badly needed an equitable jurisdiction where fairness, extenuating circumstances, and broad social mores could overrule the letter of the law. The formal tropes of their Complaints negotiate the tension between these two conceptions of justice and reveal how that tension relates to early seventeenth century economic culture, where customary ideas about patronage and hierarchical obligations coexisted with emerging notions of self-interest and contractual equality. In appealing to the court with older but still vibrant discourses of social justice and mutual obligation, plaintiffs modulated their Complaints with expressions of deference and helplessness. Their pleadings therefore take the sophisticated rhetorical form of self-assertion articulated as abject submission. The documents are highly mediated by lawyers and institutional constraints, but nevertheless reveal subordinates tactically using expressions of weakness to elicit pathos and use the ideology of paternalism against their masters.

  8. Annuity payments can increase patient access to innovative cell and gene therapies under England's net budget impact test.

    Science.gov (United States)

    Jørgensen, Jesper; Kefalas, Panos

    2017-01-01

    Background: Cell and gene therapies have the potential to provide therapeutic breakthroughs, but the high costs of researching, developing, manufacturing and delivering them translate into prices that may challenge healthcare budgets. Various measures exist that aim to address the affordability challenge, including reducing price, limiting patient numbers and/or linking remuneration to product performance. Objective: To explore how the net budget impact test recently introduced in England can affect patient access to high-value, one-off cell and gene therapies, and how managed entry agreements can improve access. Methods: We use a hypothetical example where a new high-value, one-off therapy launches in an indication where it displaces a relatively low cost chronic treatment. We calculate the number of patients that can be treated without exceeding the £20 million net budget impact threshold, and compare results for scenarios where a full upfront payment is used, and where annuity-based payments are used. Results: Charging a full upfront payment at the time of treatment can lead to suboptimal patient access. Conclusion: Annuity-based payments in combination with an outcomes-based remuneration scheme reduce consequences of decision uncertainty and can increase patient access, without exceeding the net budget impact test.

  9. Non-social adaptation defers a tragedy of the commons in Pseudomonas aeruginosa quorum sensing.

    Science.gov (United States)

    Asfahl, Kyle L; Walsh, Jessica; Gilbert, Kerrigan; Schuster, Martin

    2015-08-01

    In a process termed quorum sensing (QS), the opportunistic bacterial pathogen Pseudomonas aeruginosa uses diffusible signaling molecules to regulate the expression of numerous secreted factors or public goods that are shared within the population. But not all cells respond to QS signals. These social cheaters typically harbor a mutation in the QS receptor gene lasR and exploit the public goods produced by cooperators. Here we show that non-social adaptation under growth conditions that require QS-dependent public goods increases tolerance to cheating and defers a tragedy of the commons. The underlying mutation is in the transcriptional repressor gene psdR. This mutation has no effect on public goods expression but instead increases individual fitness by derepressing growth-limiting intracellular metabolism. Even though psdR mutant populations remain susceptible to invasion by isogenic psdR lasR cheaters, they bear a lower cheater load than do wild-type populations, and they are completely resistant to invasion by lasR cheaters with functional psdR. Mutations in psdR also sustain growth near wild-type levels when paired with certain partial loss-of-function lasR mutations. Targeted sequencing of multiple evolved isolates revealed that mutations in psdR arise before mutations in lasR, and rapidly sweep through the population. Our results indicate that a QS-favoring environment can lead to adaptations in non-social, intracellular traits that increase the fitness of cooperating individuals and thereby contribute to population-wide maintenance of QS and associated cooperative behaviors.

    Purpose: To report the outcomes of repeat stereotactic radiosurgery (SRS), deferring whole-brain radiation therapy (WBRT), for distant intracranial recurrences and identify factors associated with prolonged overall survival (OS). Patients and Methods: We retrospectively identified 652 metastases in 95 patients treated with 2 or more courses of SRS for brain metastases, deferring WBRT. Cox regression analyzed factors predictive for OS. Results: Patients had a median of 2 metastases (range, 1-14) treated per course, with a median of 2 courses (range, 2-14) of SRS per patient. With a median follow-up after first SRS of 15 months (range, 3-98 months), the median OS from the time of the first and second course of SRS was 18 (95% confidence interval [CI] 15-24) and 11 months (95% CI 6-17), respectively. On multivariate analysis, histology, graded prognostic assessment score, aggregate tumor volume (but not number of metastases), and performance status correlated with OS. The 1-year cumulative incidence, with death as a competing risk, of local failure was 5% (95% CI 4-8%). Eighteen (24%) of 75 deaths were from neurologic causes. Nineteen patients (20%) eventually received WBRT. Adverse radiation events developed in 2% of SRS sites. Conclusion: Multiple courses of SRS, deferring WBRT, for distant brain metastases after initial SRS, seem to be a safe and effective approach. The graded prognostic assessment score, updated at each course, and aggregate tumor volume may help select patients in whom the deferral of WBRT might be most beneficial.

  13. A comparison of high-order explicit Runge–Kutta, extrapolation, and deferred correction methods in serial and parallel

    Ketcheson, David I.

    2014-06-13

    We compare the three main types of high-order one-step initial value solvers: extrapolation, spectral deferred correction, and embedded Runge–Kutta pairs. We consider orders four through twelve, including both serial and parallel implementations. We cast extrapolation and deferred correction methods as fixed-order Runge–Kutta methods, providing a natural framework for the comparison. The stability and accuracy properties of the methods are analyzed by theoretical measures, and these are compared with the results of numerical tests. In serial, the eighth-order pair of Prince and Dormand (DOP8) is most efficient. But other high-order methods can be more efficient than DOP8 when implemented in parallel. This is demonstrated by comparing a parallelized version of the wellknown ODEX code with the (serial) DOP853 code. For an N-body problem with N = 400, the experimental extrapolation code is as fast as the tuned Runge–Kutta pair at loose tolerances, and is up to two times as fast at tight tolerances.

  14. The evolution of prestige: freely conferred deference as a mechanism for enhancing the benefits of cultural transmission.

    Science.gov (United States)

    Henrich, J; Gil-White, F J.

    2001-05-01

    This paper advances an "information goods" theory that explains prestige processes as an emergent product of psychological adaptations that evolved to improve the quality of information acquired via cultural transmission. Natural selection favored social learners who could evaluate potential models and copy the most successful among them. In order to improve the fidelity and comprehensiveness of such ranked-biased copying, social learners further evolved dispositions to sycophantically ingratiate themselves with their chosen models, so as to gain close proximity to, and prolonged interaction with, these models. Once common, these dispositions created, at the group level, distributions of deference that new entrants may adaptively exploit to decide who to begin copying. This generated a preference for models who seem generally "popular." Building on social exchange theories, we argue that a wider range of phenomena associated with prestige processes can more plausibly be explained by this simple theory than by others, and we test its predictions with data from throughout the social sciences. In addition, we distinguish carefully between dominance (force or force threat) and prestige (freely conferred deference).

  15. Accounting choices in Brazil: identifying the characteristics of publicly traded companies that opted to maintain versus derecognise deferred assets

    Directory of Open Access Journals (Sweden)

    Fernando Drago Lorencini

    2012-04-01

    Full Text Available The issuance of Brazilian Law 11.638/2007 is a critical step in the convergence of the Brazilian Generally Accepted Accounting Principles (GAAPs towards International Financial Reporting Standards. After the law was implemented and later modified by Provisional Executive Order 449/2008 (converted into Law 11.941/2009, certain accounting choices were allowed during the transition period. The Brazilian GAAPs allowed for restructuring costs and costs related to opening a new facility to be recognised as assets. As a transitional provision, companies were allowed to choose between maintaining or eliminating these values. In this paper, we attempted to identify which company characteristics were associated with this accounting choice. The final sample consisted of Brazilian companies listed on the BM & FBOVESPA, and a logistic regression identified two characteristics. Participation in one of the three different corporate governance levels of the BM & FBOVESPA was associated with the choice to derecognise the deferred assets, while companies decided to maintain the deferred asset if it was relatively large. The empirical evidence reported here contributes to the literature by explaining the manner in which a set of firm characteristics is related to a firm's accounting choices.

    2015-12-01

    Full Text Available Most information underlying the decision to invest at the level of a company, are provided by the accountancy, this becoming today a common language with respect to the businesses on the international markets, and the accountancy normalization was extrapolated from the national level to the international level, due to the needs concerning the comparability and the transparency of the entities financial statements, without considering the geopolitical area where they were built. These issues justify the approaches for improving both accounting treatments and the procedures for elaborating and presenting data within the financial statements such that the users to benefit from credible and transparent information. One of the major issues arising with respect to the performance of an entity aims to prepare a unique situation on the company performance, namely:“the statement of the comprehensive income”, having as primordial objective the facility of forecasting the performance, within which the deferred taxes generated by the subventions for investments are an essential element with an important predictive value. In this context, starting from the main differences between the provisions of the national, Anglo-Saxon accounting regulations and those of the international reference system with respect to the predictive value of the deferred taxes and continuing with the occurrence and evolution of the deferred taxes generated by the subventions for investments, the study proposes to highlight the predictive value of the deferred taxes generated by the subventions for investments, provided o the users by the information of annual financial statements.

    2013-12-01

    Imitative learning has been described in naturalistic studies for different cultures, but lab-based research studying imitative learning across different cultural contexts is almost missing. Therefore, imitative learning was assessed with 18-month-old German middle-class and Cameroonian Nso farmer infants - representing two highly different eco-cultural contexts associated with different cultural models, the psychological autonomy and the hierarchical relatedness - by using the deferred imitation paradigm. Study 1 revealed that the infants from both cultural contexts performed a higher number of target actions in the deferred imitation than in the baseline phase. Moreover, it was found that German middle-class infants showed a higher mean imitation rate as they performed more target actions in the deferred imitation phase compared with Cameroonian Nso farmer infants. It was speculated that the opportunity to manipulate the test objects directly after the demonstration of the target actions could enhance the mean deferred imitation rate of the Cameroonian Nso farmer infants which was confirmed in Study 2. Possible explanations for the differences in the amount of imitated target actions of German middle-class and Cameroonian Nso farmer infants are discussed considering the object-related, dyadic setting of the imitation paradigm with respect to the different learning contexts underlying the different cultural models of learning.

    Evaluate intravitreal 0.5 mg ranibizumab or 4 mg triamcinolone combined with focal/grid laser compared with focal/grid laser alone for treatment of diabetic macular edema (DME). Multicenter, randomized clinical trial. A total of 854 study eyes of 691 participants with visual acuity (approximate Snellen equivalent) of 20/32 to 20/320 and DME involving the fovea. Eyes were randomized to sham injection + prompt laser (n=293), 0.5 mg ranibizumab + prompt laser (n=187), 0.5 mg ranibizumab + deferred (> or =24 weeks) laser (n=188), or 4 mg triamcinolone + prompt laser (n=186). Retreatment followed an algorithm facilitated by a web-based, real-time data-entry system. Best-corrected visual acuity and safety at 1 year. The 1-year mean change (+/-standard deviation) in the visual acuity letter score from baseline was significantly greater in the ranibizumab + prompt laser group (+9+/-11, Peyes at baseline (n=273), visual acuity improvement in the triamcinolone + prompt laser group appeared comparable to that in the ranibizumab groups. No systemic events attributable to study treatment were apparent. Three eyes (0.8%) had injection-related endophthalmitis in the ranibizumab groups, whereas elevated intraocular pressure and cataract surgery were more frequent in the triamcinolone + prompt laser group. Two-year visual acuity outcomes were similar to 1-year outcomes. Intravitreal ranibizumab with prompt or deferred laser is more effective through at least 1 year compared with prompt laser alone for the treatment of DME involving the central macula. Ranibizumab as applied in this study, although uncommonly associated with endophthalmitis, should be considered for patients with DME and characteristics similar to those in this clinical trial. In pseudophakic eyes, intravitreal triamcinolone + prompt laser seems more effective than laser alone but frequently increases the risk of intraocular pressure elevation.

    市场化改革以来,中国建立了统账结合的基本养老保险制度。作为基本养老保险重要补充的企业年金也有了很大发展。但目前企业年金仍然存在以下主要问题:国企、外企、民企加入的差异性较大;员工激励功能发挥有限;税收优惠政策不到位;投资运营环境不够健全;运作主体和流程复杂繁琐。鉴于此,中国企业年金的未来发展,需要处理好企业年金与基本养老保险和职业年金之间的关系,做实基本养老保险个人账户,简化企业年金的运作主体和流程,降低企业年金的准入门槛,加强对企业年金的学术研究。%Since the implementation of the market-oriented reform,China has set up a basic pension in-surance system which is combined with social pooling account and individual account.As an important supplementary pillar of basic old-age insurance,enterprise annuity has developed rapidly.Based on qualitative research,this paper analyses the major problems of enterprise annuity at this stage.First, the participating rates differ significantly among state-owned enterprises,foreign enterprises,and pri-vate enterprises.Second,enterprise annuity plays a limited role in motivating talents.Third,the tax preference policy is still vague.Fourth,the investment environment of enterprise annuity fund is not perfect.Fifth,the operation mechanism of enterprise annuity is rather complex.To address these prob-lems,the following is proposed:in the future,the Chinese enterprise annuity should deal with the re-lationship between basic old-age insurance and enterprise annuity;policy recommendations should be made to consolidate the individual account fund and simplify the operation mechanism of enterprise an-nuity;barriers to joining enterprise annuity plan should be reduced, and academic research of enterprise annuity be strengthened.

  7. Is selective attention the basis for selective imitation in infants? An eye-tracking study of deferred imitation with 12-month-olds.

    2014-08-01

    Infants and children do not blindly copy every action they observe during imitation tasks. Research demonstrated that infants are efficient selective imitators. The impact of selective perceptual processes (selective attention) for selective deferred imitation, however, is still poorly described. The current study, therefore, analyzed 12-month-old infants' looking behavior during demonstration of two types of target actions: arbitrary versus functional actions. A fully automated remote eye tracker was used to assess infants' looking behavior during action demonstration. After a 30-min delay, infants' deferred imitation performance was assessed. Next to replicating a memory effect, results demonstrate that infants do imitate significantly more functional actions than arbitrary actions (functionality effect). Eye-tracking data show that whereas infants do not fixate significantly longer on functional actions than on arbitrary actions, amount of fixations and amount of saccades differ between functional and arbitrary actions, indicating different encoding mechanisms. In addition, item-level findings differ from overall findings, indicating that perceptual and conceptual item features influence looking behavior. Looking behavior on both the overall and item levels, however, does not relate to deferred imitation performance. Taken together, the findings demonstrate that, on the one hand, selective imitation is not explainable merely by selective attention processes. On the other hand, notwithstanding this reasoning, attention processes on the item level are important for encoding processes during target action demonstration. Limitations and future studies are discussed.

    Summary Background The optimum time to start antiretroviral therapy for children diagnosed with HIV infection after 1 year of age is unknown. We assessed whether antiretroviral therapy could be deferred until CD4 percentages declined to less than 15% without affecting AIDS-free survival. Methods In our multicentre, randomised, open-label trial at nine research sites in Thailand and Cambodia, we enrolled children aged 1–12 years who were infected with HIV and had CD4 percentages of 15–24%. Participants were randomly assigned (1:1) by a minimisation scheme to start antiretroviral therapy at study entry (early treatment group) or antiretroviral therapy to start when CD4 percentages declined to less than 15% (deferred treatment group). The primary endpoint was AIDS-free survival (based on US Centers for Disease Control and Prevention category C events) at week 144, assessed with the Kaplan-Meier analysis and the log-rank approach. This study is registered with ClinicalTrials.gov, number NCT00234091. Findings Between March 28, 2006, and Sept 10, 2008, we enrolled 300 Thai and Cambodian children infected with HIV, with a median age of 6·4 years (IQR 3·9–8·4). 150 children were randomly allocated early antiretroviral therapy (one participant was excluded from analyses after withdrawing before week 0) and 150 children were randomly allocated deferred antiretroviral therapy. Median baseline CD4 percentage was 19% (16–22%). 69 children (46%) in the deferred treatment group started antiretroviral therapy during the study. AIDS-free survival at week 144 in the deferred treatment group was 98·7% (95% CI 94·7–99·7; 148 of 150 patients) compared with 97·9% (93·7–99·3; 146 of 149 patients) in the early treatment group (p=0·6). Interpretation AIDS-free survival in both treatment groups was high. This low event rate meant that our study was underpowered to detect differences between treatment start times and thus additional follow-up of study participants or

    Full Text Available Since the early 90s, Italy has undergone radical changes in the regulations of the public pension system aimed at mending its main drawbacks and improving sustainability in the long run. The reforms were intended to recover the national economy through a significant reduction of benefits by increasing, particularly for younger people, individual responsibility for the accumulation of retirement wealth. Adopting an enhanced version of the Theory of Planned Behavior (TPB, which includes affective reactions, the present paper aims to understand the factors influencing the intention to enroll in a private pension plan through the purchase of longevity annuity coverage on the part of young adults. A purposive sample of 7480 Italian people aged 25–35 participated in the survey. Collected data were analyzed adopting an ordinal logistic regression (OLR model. The findings confirm the predictive power of the TPB in the financial field of longevity annuity buying, show that anticipated affective reactions increase the predictive power of the TPB model, and reveal that the influence of the investigated constructs varies alongside people’s willingness to purchase. The outcomes provide useful recommendations to the policy maker and private companies to favor the adoption of wide-spread desired behaviors among citizenships.

    随着我国人口老龄化加剧及各事业单位从业人数不断增加,退休养老保险成为社会一大问题。为了缓解因此而产生的政府财政支出压力,改变我国事业单位与普通企业不同的养老保险制度的格局以促进社会公平,国务院于2009年初开始在全国五省市开始事业单位职业年金试点工作,但目前实施进度慢,效果欠佳。本文分析了我国职业年金实行初期存在制度对接、事业单位资金不足和规划不够等问题,并提出了一系列措施建议,以促进职业年金能在试点初期有所成效,进而为其能够在全国全面推广打下基础。%Due to the increasing of the number of employees in public institutions and the continuous aging of population, retirement pension insurance is becoming a big social issue in China. In order to alleviate the resulting government spending pressure and change the different pension insurance systems between public institutions and general corporates, which will promote social equity, the State Council started to reform the occupational annuity system of public institutions in five provinces and cities in early 2009, but the current progress of the reform is ineffective and slow. This paper analyzed the problems in implementing China's occupational annuity system in the early stage which mainly related to system interfacing, insufficient funds and inadequate planning in public institutions and so on. At last, this paper recommended a series of measures in order to effectively promote the occupational annuity system, which would lay the foundation for nationwide rolling-out.

    Preterm birth is the most important single determinant of adverse outcome in the United Kingdom; one in every 70 babies (1.4%) is born before 32 weeks (very preterm), yet these births account for over half of infant deaths.Deferring cord clamping allows blood flow between baby and placenta to continue for a short time. This often leads to increased neonatal blood volume at birth and may allow longer for transition to the neonatal circulation. Optimal timing for clamping the cord remains uncertain, however. The Cochrane Review suggests that deferring umbilical cord clamping for preterm births may improve outcome, but larger studies reporting substantive outcomes and with long-term follow-up are needed. Studies of the physiology of placental transfusion suggest that flow in the umbilical cord at very preterm birth may continue for several minutes. This pilot trial aims to assess the feasibility of conducting a large randomised trial comparing immediate and deferred cord clamping in the UK. Women are eligible for the trial if they are expected to have a live birth before 32 weeks gestation. Exclusion criteria are known monochorionic twins or clinical evidence of twin-twin transfusion syndrome, triplet or higher order multiple pregnancy, and known major congenital malformation. The interventions will be cord clamping within 20 seconds compared with cord clamping after at least two minutes. For births with cord clamping after at least two minutes, initial neonatal care is at the bedside. For the pilot trial, outcomes include measures of recruitment, compliance with the intervention, retention of participants and data quality for the clinical outcomes.Information about the trial is available to women during their antenatal care. Women considered likely to have a very preterm birth are approached for informed consent. Randomisation is close to the time of birth. Follow-up for the women is for one year, and for the children to two years of age (corrected for gestation

    Undocumented immigrant young adults growing up in the United States face significant challenges. For those qualified, the Deferred Action for Childhood Arrivals (DACA) program's protections may alleviate stressors, with implications for their mental health and wellbeing (MHWB). We conducted nine focus groups with 61 DACA-eligible Latinos (ages 18-31) in California to investigate their health needs. Participants reported MHWB as their greatest health concern and viewed DACA as beneficial through increasing access to opportunities and promoting belonging and peer support. Participants found that DACA also introduced unanticipated challenges, including greater adult responsibilities and a new precarious identity. Thus, immigration policies such as DACA may influence undocumented young adults' MHWB in expected and unexpected ways. Research into the impacts of policy changes on young immigrants' MHWB can guide stakeholders to better address this population's health needs. MHWB implications include the need to reduce fear of deportation and increase access to services.

    For almost 45 years, the experience of Jewish children who were hidden during World War II was considered to be of little importance, particularly with respect to what had taken place in the concentration camps. Their very history was ignored in the many accounts of the Holocaust. It was only at the end of the 1980s that their experience began to be thought of as potentially traumatic. In this paper, the authors report on their psychoanalytical research project concerning the psychological outcomes of those experiences that had remained concealed for such an extraordinarily long latency period. The results are based on the analysis of 60 accounts and on psychoanalytically-oriented group work. The authors show that the trauma experienced by those hidden children was triggered by the retroactive effect of a deferred action [après-coup]. Copyright © 2010 Institute of Psychoanalysis.

    The Simulation drilling system provides a good service for the enterprises and the emergency departments at present. However, it still has quite a few drawbacks. Such as the lack of modern graphic pipeline support, the excessive computation of scene rendering on the condition of multiple lights, the poor rendering effects caused by that it cannot make full use of hardware etc. In order to solve those problems, this paper is designed and implemented with a deferred shading pipeline for simulation drilling system. This pipeline is based on the Blinn-Phong lighting model, which builds a compressed G-buffer layout and uses Light volume to model the light source. The final experiment indicates that under the multiple lights circumstances, the deferred shading expressed in this paper will be more efficient than the conventional forward shading.%模拟演练系统为企业和应急部门提供了强大的服务,然而目前的模拟演练系统中存在缺乏现代图形流水线,多光源情况下存在场景渲染计算量过多,不能充分利用硬件而导致的渲染效果差等问题。为了解决这些问题,本文针对模拟演练系统,设计和实现了延迟渲染流水线,它依据Blinn-Phong光照模型,构建了一种压缩的G-Buffer布局,并使用Light Volume来对光源进行建模。最后实验表明,在多光源情况下,此文中提出的延迟渲染比传统的正向渲染有更高的效率。

Therefore, the pension annuity under the system has important impact on theory and practice. This paper investigates the actuarial function of retirement annuity under the flexible retirement system. Under the hypothesis that the distribution of the retirement age is binomial distribution, the interest rate is decided by the discontinuous stochastic differential equations with jumps, and the death intensity is decided by Feller process with a jump. The formulas of the retirement annuity are proposed, including the life annuities, insurance, net premiums and insurance actuarial present value of second moment, and the sim-ulatived estimation for the relevant actuarial functions is derived. These formulas provide the basis of the actuarial analysis of insurance and balance insurance under the flexible retirement system, thus they can be applied for the old-age insurance system and control of risk pension account in China.

    Enterprise annuity is the second pillar of endowment insurance system in our country,which is difficult to release the pressure of primary endowment insurance and can't play the role of promoting economic development be-cause of the slow development of small and medium-sized enterprise annuity system in our country. This paper ana-lyzes the reasons of slow development of small and medium-sized enterprise annuity system in China, mainly in-cludes the country lacking the corresponding policy support, enterprises lacking of internal and external environ-ment of building enterprise annuity, employees lacking of consciousness of participating in the enterprise annuity system. To solve these problems, this paper puts forward that states should publish relevant preferential policies to encourage small and medium-sized enterprises as soon as possible to establish pension system, promote collective occupational pension plan, boost the development of small and medium-sized enterprises and improve the ability of enterprise annuity payment, play a role of trade unions and change the concept of the workers, at last promote the development of small and medium-sized enterprise annuity system.%企业年金是我国养老保险体系中的第二支柱,但我国中小企业年金制度发展缓慢,难以释放基本养老保险的压力,不能起到促进经济发展的作用。分析我国中小企业年金制度发展迟缓的原因,主要包括国家缺乏相应的政策支持、企业缺乏建立企业年金的内外部环境、职工缺乏参加企业年金制度的意识和动力,针对这些问题,论文提出国家应尽快出台相关政策优惠鼓励中小企业建立年金制度、推广集合年金计划、助力中小企业发展,提高企业年金缴费能力、发挥工会作用,转变职工观念,推动发展中小企业年金制度。

    Full Text Available BACKGROUND: Measures to prevent chronic calcineurin inhibitor (CNI toxicity have included limiting exposure by switching to sirolimus (SIR. SIR may favorably influence T regulator cell (T(reg population. This randomized controlled trial compares the effect of switching from CNI to SIR on glomerular filtration rate (GFR and T(reg frequency. METHODS: In this prospective open label randomized trial, primary living donor kidney transplant recipients on CNI-based immunosuppression were randomized to continue CNI or switched to sirolimus 2 months after surgery; 29 were randomized to receive CNI and 31 to SIR. All patients received mycophenolate mofetil and steroids. The main outcome parameter was estimated GFR (eGFR at 180 days. T(reg population was estimated by flowcytometry. RESULTS: Baseline characteristics in the two groups were similar. Forty-eight patients completed the trial. At six months, patients in the SIR group had significantly higher eGFR as compared to those in the CNI group (88.94 ± 11.78 vs 80.59 ± 16.51 mL/min, p = 0.038. Patients on SIR had a 12 mL/min gain of eGFR of at the end of six months. Patients in the SIR group showed significant increase in T(reg population at 30 days, which persisted till day 180. There was no difference in the adverse events in terms of number of acute rejection episodes, death, infections, proteinuria, lipid profile, blood pressure control and hematological parameters between the two groups. Four patients taking SIR developed enthesitis. No patient left the study or switched treatment because of adverse event. CONCLUSIONS: A deferred pre-emptive switch over from CNI to SIR safely improves renal function and T(reg population at 6 months in living donor kidney transplant recipients.

    An adverse intrauterine environment leads to permanent physiological changes including vascular tone regulation, potentially influencing the risk for adult vascular diseases. We therefore aimed to monitor responsive NOS3 expression in human umbilical artery endothelial cells (HUAEC) and to study the underlying epigenetic signatures involved in its regulation. NOS3 and STAT3 mRNA levels were elevated in HUAEC of patients who suffered from placental insufficiency. 5-hydroxymethylcytosine, H3K9ac and Histone 2A (H2A).Zac at the NOS3 transcription start site directly correlated with NOS3 mRNA levels. Concomitantly, we observed entangled histone acetylation patterns and NOS3 response upon hypoxic conditions in vitro. Knock-down of either NOS3 or STAT3 by RNAi provided evidence for a functional NOS3/STAT3 relationship. Moreover, we recognized massive turnover of Stat3 at a discrete binding site in the NOS3 promoter. Interestingly, induced hyperacetylation resulted in short-termed increase of NOS3 mRNA followed by deferred decrease indicating that NOS3 expression could become self-attenuated by co-expressed intronic 27 nt-ncRNA. Reporter assay results and phylogenetic analyses enabled us to propose a novel model for STAT3-3'-UTR targeting by this 27-nt-ncRNA. An adverse intrauterine environment leads to adaptive changes of NOS3 expression. Apparently, a rapid NOS3 self-limiting response upon ectopic triggers co-exists with longer termed expression changes in response to placental insufficiency involving differential epigenetic signatures. Their persistence might contribute to impaired vascular endothelial response and consequently increase the risk of cardiovascular disease later in life.

Reverse mortgage is schemed out to be a ifnancial instrument to solve "house rich, cash poor" problem that may occur among the elderly, and reasonable pricing is the key to make" the Housing Endowment" run smoothly. Under the risk-neutral conditions, dynamic natures should be taken into account by three main factors those are property value, interest rate and life expectancy. The present value of innovative uses of the borrower to pay the loan guarantee insurance premiums equal to the losses claimed by the insurance company is now expected value, without any right of redemption for a lifetime annuity reverse mortgage loan pricing, using CIR model, LC models and jump diffusion models for interest rates, respectively, mortality and prices to ift the dynamic volatility. The results show that the annuity value amounts of borrowers are positive correlation with their ages as well as the house values, and negative correlation with interest rates; Sensitivity analysis of pricing results expose that the lfuctuations on the housing prices impact the payment of annuity amount most. And it can be found from the analysis of mortality that if we neglect to improve the borrower mortality, the amount of the annuity payment will be overestimated.%随着我国人口老龄化程度日益加剧,养老服务需求随之增大,“以房养老”作为新型的养老模式应运而生。反向抵押贷款作为针对老年人可能面临的“房子富人、现金穷人”尴尬而设计出的一种金融创新工具,能否对其进行科学合理定价,是“以房养老”顺利开展的关键。在风险中性条件下,同时考虑房产价值、利率和预期寿命三大主要因素的动态性,创新性地采用借款者向保险公司缴纳保证保险的保费现值等于贷款者向保险公司预期索赔损

    It has been 10 years since the commercialized operation of China’s enterprise annuity in the year 2006;though the market has become more mature,there is still gap between the development of this market and the second pillar of the world’s main economic entities. Though the enterprise annuity is not mandatory,the development of that will be deeply influenced by tax related policies;and this market could be called quasi-policy market. China’s enterprise annuity related policies can be classified as core system,fiscal system and other supporting systems. During the period of“the 13th Five Year Plan”,and facing the aging problem,China will further deepen reform in pension system;and enterprise annuity in the future will show four major trends:first,China will strengthen support to the second pillar,and the three-pillar system will be more harmonious;second,the pension investment restrictions will be gradually relieved;third,the new technology will enlarge customer choices,therefore bring more innovation;and fourth,financial capital,especially pension capital,will be deeply involved in the pension industry chain integration.%我国企业年金从2006年正式商业化运作开始,至今已有10年时间,市场日渐成熟,但是与世界主要经济体养老保障体系第二支柱的发展仍存在较大差距。企业年金虽然不具有强制性,但其发展受税收优惠等政策影响较大,可称为准政策性市场。我国企业年金发展中的政策主要分为核心制度、财税制度及其他配套制度等三大类。“十三五”期间,面对日益严峻的人口老龄化形势,我国将进一步深化养老体制改革,企业年金未来将呈现四大发展趋势:一是国家加大了对第二支柱的扶持力度,三支柱体系将更趋协调;二是结合国际经验和近期政策导向,养老金投资限制将逐步放宽;三是新技术将放大客户选择权,倒逼行业创新;四是金融资本特

    我国的企业年金制度已有10余年历史,但整体水平仍相对滞后。无论是从资产规模、覆盖率和替代率,还是从税收优惠政策来看,我国企业年金的发展与OECD国家相比还存在较大差距。加快建设企业年金,应扩大覆盖面,促进集合年金和职业年金的发展;提高替代率,完善企业年金的税收优惠政策。%China's enterprise annuity has established more than 10 years, but the overall level is still lagged. There is a big gap of employer pension between-in China and OECD countries on the factors of asset size, coverage rate, and replacement rate and tax preferential policies. Therefore, the authors put forward accelerating enterprise annuity construction and expanding it covering scale, promoting the development of occupational pensions, enhance substitutability, perfect tax preferential policy on enterprise annuity.

    This study determined the safety of deferring coronary revascularization based on a fractional flow reserve (FFR) value > or = 0.75 in a series of consecutive unselected coronary patients with moderate coronary lesions, including patients with unstable angina, myocardial infarction (MI), and/or positive noninvasive test findings. The study included 201 consecutive coronary patients (mean age 62 +/- 10 years; 65% men) with 231 lesions evaluated by FFR measurement for which revascularization was deferred based on a FFR value > or = 0.75. Lesions associated with a positive noninvasive test result were those located in an artery supplying a myocardial territory in which myocardial ischemia was demonstrated by a noninvasive test. Cardiac events (cardiac death, MI, revascularization) and Canadian Cardiovascular Society angina class were evaluated at follow-up. Indications for coronary angiography included unstable angina or MI (62%), stable angina (30%), or atypical chest pain (8%). Forty-four patients (22%) had > or = 1 coronary lesion associated with a positive noninvasive test result in which FFR was evaluated. Mean FFR value was 0.87 +/- 0.06 and mean lesion percent diameter stenosis was 41 +/- 8%. At 11 +/- 6 months of follow-up, cardiac events occurred in 20 patients (10%), and no significant differences were observed between patients with unstable angina or MI and those with stable angina (9% vs 13%, p = 0.44) or between patients with and without lesions associated with positive noninvasive test results (9% vs 10%, p = 1.00). At the end of follow-up, 88% of patients were asymptomatic in angina class 0 or I, with no differences across various groups. In conclusion, these results suggest that patients with moderate coronary lesions can be safely managed without revascularization on the basis of FFR measurements, irrespective of clinical presentation and/or presence of positive noninvasive test results.

    We analyzed clinical progression among persons diagnosed with HIV at the time of an AIDS-defining event, and assessed the impact on outcome of timing of combined antiretroviral treatment (cART). Retrospective, European and Canadian multicohort study.. Patients were diagnosed with HIV from 1997-2004 and had clinical AIDS from 30 days before to 14 days after diagnosis. Clinical progression (new AIDS event, death) was described using Kaplan-Meier analysis stratifying by type of AIDS event. Factors associated with progression were identified with multivariable Cox regression. Progression rates were compared between those starting early (AIDS event) or deferred (30-270 days after AIDS event) cART. The median (interquartile range) CD4 count and viral load (VL) at diagnosis of the 584 patients were 42 (16, 119) cells/µL and 5.2 (4.5, 5.7) log(10) copies/mL. Clinical progression was observed in 165 (28.3%) patients. Older age, a higher VL at diagnosis, and a diagnosis of non-Hodgkin lymphoma (NHL) (vs. other AIDS events) were independently associated with disease progression. Of 366 patients with an opportunistic infection, 178 (48.6%) received early cART. There was no significant difference in clinical progression between those initiating cART early and those deferring treatment (adjusted hazard ratio 1.32 [95% confidence interval 0.87, 2.00], p = 0.20). Older patients and patients with high VL or NHL at diagnosis had a worse outcome. Our data suggest that earlier initiation of cART may be beneficial among HIV-infected patients diagnosed with clinical AIDS in our setting.

    Enterprise annuity is the second pillars of the social security, but it is not well carried out in china. As the taxation taken as an important tool of national income adjustment, the preferential tax policy should be treated differently. To achieve social fairness and improve employee participation in pension plans, we should implement different preferential tax policies based on different income groups.%企业年金作为我国社会养老保险制度中的第二大支柱,其发展状况在国内并不理想。而本文的研究认为税收作为国民收入调节的重要工具,其税惠政策应有所区别对待。针对不同的收入群体来实施税收优惠政策,将有利于实现社会的公平和提高企业员工参与年金计划的积极性。

    Lenczewski, Romuald

    2008-01-01

    We show that the operatorial framework developed by Voiculescu for free random variables can be extended to arrays of random variables whose multiplication imitates matricial multiplication. The associated notion of independence, called matricial freeness, can be viewed as a generalization of both freeness and monotone independence. At the same time, the sums of matricially free random variables, called random pseudomatrices, are closely related to Gaussian random matrices. The main results presented in this paper concern the standard and tracial central limit theorems for random pseudomatrices and the corresponding limit distributions which can be viewed as matricial generalizations of semicirle laws.

    The Princeton Variability Survey (PVS) is a robotic survey which makes use of readily available, ``off-the-shelf'' type hardware products, in conjunction with a powerful set of commercial software products, in order to monitor and discover variable objects in the night sky. The main goal of the PVS has been to devise an automated telescope and data reduction system, requiring only moderate technical and financial resources to assemble, which may be easily replicated by the dedicated amateur, a student group, or a professional and used to study and discover a variety of variable objects, such as stars. This paper describes the hardware and software components of the PVS device, as well as observational results from the initial season of the PVS, including the discovery of a new bright variable star.

    推迟退休年龄、延迟领取养老金年龄的主要影响群体是在职职工,本文使用广东省21个地市对在职职工的问卷调查数据,探索该政策能否可行的经验证据。结果显示,男职工选择在55岁之前退休的占55%,女职工选择在50岁之前退休的占41.2%,表明在职职工存在明显的提前退休倾向,推迟退休并不符合在职职工预期。0rdinal Logistic回归表明参加养老金制度年数对男女职工预期退休年龄的影响均显著为负,表明参加养老金制度越久,预期退休年龄越早;Binary Logistic回归也证实参加养老金制度年数越久,提前退休可能性越大。实证结果说明基本养老保险制度不能激励职工推迟退休、延迟领取养老金。为此,本文提出了对应的四点改革建议。%Since the mainly affected group of deferring retirement age and postponing the earliest age for pension benefit is the on-job workers, this article uses survey data from 21 cities in GuangDong province to investigate the planned retirement age of workers. The results show that 55% of male workers will choose to retire before 55, 41.2% of female workers will choose to retire before 50, which demonstrate an early retirement tendency. After controlling the effect of other factors, the results of Ordinal Logistic model demonstrate that participation years of pension program have a significantly negative effect on planned retirement age of the workers. The results of binary logistic model also confirm that participation years have a significantly negative effect on the dummy variable of early retirement. These empirical evidences indicate that deferring retirement age doesn't match the expectation of on-job workers and current old-age insurance system also can't encourage workers to postpone the earliest age of pension benefit. At last, this article puts forward a series of policy suggestions.

    To determine the accuracy of 320-row multidetector coronary computed tomography angiography (M320-CCTA) to detect functional stenoses using fractional flow reserve (FFR) as the reference standard and to predict revascularisation in stable coronary artery disease. One hundred and fifteen patients (230 vessels) underwent M320-CCTA and FFR assessment and were followed for 18 months. Diameter stenosis on invasive angiography (ICA) and M320-CCTA were assessed by consensus by two observers and significant stenosis was defined as ≥50 %. FFR ≤0.8 indicated functionally significant stenoses. M320-CCTA had 94 % sensitivity and 94 % negative predictive value (NPV) for FFR ≤0.8. Overall accuracy was 70 %, specificity 54 % and positive predictive value 65 %. On receiver operating characteristic (ROC) curve analysis, the area under the curve (AUC) for CCTA to predict FFR ≤0.8 was 0.74 which was comparable with ICA. The absence of a significant stenosis on M320-CCTA was associated with a 6 % revascularisation rate. M320-CCTA predicted revascularisation with an AUC of 0.71 which was comparable with ICA. M320-CCTA has excellent sensitivity and NPV for functional stenoses and therefore may act as an effective gatekeeper to defer ICA and revascularisation. Like ICA, M320-CCTA lacks specificity for functional stenoses and only has moderate accuracy to predict the need for revascularisation. (orig.)

  17. Classifying TDSS Stellar Variables

    Amaro, Rachael Christina; Green, Paul J.; TDSS Collaboration

    2017-01-01

    The Time Domain Spectroscopic Survey (TDSS), a subprogram of SDSS-IV eBOSS, obtains classification/discovery spectra of point-source photometric variables selected from PanSTARRS and SDSS multi-color light curves regardless of object color or lightcurve shape. Tens of thousands of TDSS spectra are already available and have been spectroscopically classified both via pipeline and by visual inspection. About half of these spectra are quasars, half are stars. Our goal is to classify the stars with their correct variability types. We do this by acquiring public multi-epoch light curves for brighter stars (rSky Survey (CSS). We then run a number of light curve analyses from VARTOOLS, a program for analyzing astronomical time-series data, to constrain variable type both for broad statistics relevant to future surveys like the Transiting Exoplanet Survey Satellite (TESS) and the Large Synoptic Survey Telescope (LSST), and to find the inevitable exotic oddballs that warrant further follow-up. Specifically, the Lomb-Scargle Periodogram and the Box-Least Squares Method are being implemented and tested against their known variable classifications and parameters in the Catalina Surveys Periodic Variable Star Catalog. Variable star classifications include RR Lyr, close eclipsing binaries, CVs, pulsating white dwarfs, and other exotic systems. The key difference between our catalog and others is that along with the light curves, we will be using TDSS spectra to help in the classification of variable type, as spectra are rich with information allowing estimation of physical parameters like temperature, metallicity, gravity, etc. This work was supported by the SDSS Research Experience for Undergraduates program, which is funded by a grant from Sloan Foundation to the Astrophysical Research Consortium.

Out of 575 Cepheids and 2322 RR Lyrae candidates from the Gaia DR1 samples located in the OGLE footprint in the sky, 559 Cepheids and 2302 RR Lyrae stars are genuine pulsators of these types. The number of misclassified stars is low indicating reliable performance of the Gaia data pipeline. The completeness of the Gaia DR1 samples of Cepheids and RR Lyrae stars is at the level of 60-75% as compared to the OGLE Collection dataset. This level of completeness is moderate and may limit the applicability of the Gaia data in many projects.

  1. Deconstructed Transverse Mass Variables

    CERN Document Server

    Ismail, Ahmed; Virzi, Joseph S; Walker, Devin G E

    2014-01-01

    Traditional searches for R-parity conserving natural supersymmetry (SUSY) require large transverse mass and missing energy cuts to separate the signal from large backgrounds. SUSY models with compressed spectra inherently produce signal events with small amounts of missing energy that are hard to explore. We use this difficulty to motivate the construction of "deconstructed" transverse mass variables which are designed preserve information on both the norm and direction of the missing momentum. We demonstrate the effectiveness of these variables in searches for the pair production of supersymmetric top-quark partners which subsequently decay into a final state with an isolated lepton, jets and missing energy. We show that the use of deconstructed transverse mass variables extends the accessible compressed spectra parameter space beyond the region probed by traditional methods. The parameter space can further be expanded to neutralino masses that are larger than the difference between the stop and top masses. ...

    A growing literature is reporting on how the terrestrial carbon cycle is experiencing year-to-year variability because of climate anomalies and trends caused by global change. As CO 2 concentration records in the atmosphere exceed 50 years and as satellite records reach over 30 years in length, we are becoming better able to address carbon cycle variability and trends. Here we review how variable the carbon cycle is, how large the trends in its gross and net fluxes are, and how well the signal can be separated from noise. We explore mechanisms that explain year-to-year variability and trends by deconstructing the global carbon budget. The CO 2 concentration record is detecting a significant increase in the seasonal amplitude between 1958 and now. Inferential methods provide a variety of explanations for this result, but a conclusive attribution remains elusive. Scientists have reported that this trend is a consequence of the greening of the biosphere, stronger northern latitude photosynthesis, more photosynthesis by semi-arid ecosystems, agriculture and the green revolution, tropical temperature anomalies, or increased winter respiration. At the global scale, variability in the terrestrial carbon cycle can be due to changes in constituent fluxes, gross primary productivity, plant respiration and heterotrophic (microbial) respiration, and losses due to fire, land use change, soil erosion, or harvesting. It remains controversial whether or not there is a significant trend in global primary productivity (due to rising CO 2, temperature, nitrogen deposition, changing land use, and preponderance of wet and dry regions). The degree to which year-to-year variability in temperature and precipitation anomalies affect global primary productivity also remains uncertain. For perspective, interannual variability in global gross primary productivity is relatively small (on the order of 2 Pg-C y -1) with respect to a large and uncertain background (123 +/- 4 Pg-C y -1), and

  4. Variable selection through CART

    CERN Document Server

    Sauvé, Marie

    2011-01-01

    This paper deals with variable selection in the regression and binary classification frameworks. It proposes an automatic and exhaustive procedure which relies on the use of the CART algorithm and on model selection via penalization. This work, of theoretical nature, aims at determining adequate penalties, i.e. penalties which allow to get oracle type inequalities justifying the performance of the proposed procedure. Since the exhaustive procedure can not be executed when the number of variables is too big, a more practical procedure is also proposed and still theoretically validated. A simulation study completes the theoretical results.

    2017-01-01

    This book describes an effective method for modeling advanced materials like polymers, composite materials and biomaterials, which are, as a rule, inhomogeneous. The thermoelastic theory with internal variables presented here provides a general framework for predicting a material’s reaction to external loading. The basic physical principles provide the primary theoretical information, including the evolution equations of the internal variables. The cornerstones of this framework are the material representation of continuum mechanics, a weak nonlocality, a non-zero extra entropy flux, and a consecutive employment of the dissipation inequality. Examples of thermoelastic phenomena are provided, accompanied by detailed procedures demonstrating how to simulate them.

    There are many sources of variability that exist in the sample collection and analysis process. This paper addresses many, but not all, sources of variability. The main focus of this paper was to better understand and estimate variability due to differences between samplers. Variability between days was also studied, as well as random variability within each sampler. Experiments were performed using multiple surface materials (ceramic and stainless steel), multiple contaminant concentrations (10 spores and 100 spores), and with and without the presence of interfering material. All testing was done with sponge sticks using 10-inch by 10-inch coupons. Bacillus atrophaeus was used as the BA surrogate. Spores were deposited using wet deposition. Grime was coated on the coupons which were planned to include the interfering material (Section 3.3). Samples were prepared and analyzed at PNNL using CDC protocol (Section 3.4) and then cultured and counted. Five samplers were trained so that samples were taken using the same protocol. Each sampler randomly sampled eight coupons each day, four coupons with 10 spores deposited and four coupons with 100 spores deposited. Each day consisted of one material being tested. The clean samples (no interfering materials) were run first, followed by the dirty samples (coated with interfering material). There was a significant difference in recovery efficiency between the coupons with 10 spores deposited (mean of 48.9%) and those with 100 spores deposited (mean of 59.8%). There was no general significant difference between the clean and dirty (containing interfering material) coupons or between the two surface materials; however, there was a significant interaction between concentration amount and presence of interfering material. The recovery efficiency was close to the same for coupons with 10 spores deposited, but for the coupons with 100 spores deposited, the recovery efficiency for the dirty samples was significantly larger (65

    1980-08-01

    While making comparative analyses of data collected by the World Fertility Survey regarding Latin America, a group of investigators of CELADE (Centro Latinoamericano de Demografia) realized that the selection of economic variables for the study of fertility had serious limitations. Such limitations did not allow the elaboration of a theory which took into account the complicated process of fertility, in all its socioeconomic, cultural, and psychological manifestations. Thus, this paper intends to lay the theoretical basis for the selection of all relevant variables, distinguishing, for example, the average fertility of women according to area of residence, place of early socialization, migrant status, social status, occupation of husband, level of instruction, occupation, and all changes in occupational activities of women in fertile age.

A lot of bright short-time flares were detected from GRS 1915+105 and they could be associated with active X-ray events. In January 2006 we detected a drop down of the quiescent fluxes from Cyg X-3 (from 100 to $\\sim$20 mJy), then the 1 Jy-flare was detected on 2 February 2006 after 18 days of quenched radio emission.

  10. Modeling Pacific Decadal Variability

    Science.gov (United States)

    Schneider, N.

    2002-05-01

    Hypotheses for decadal variability rely on the large thermal inertia of the ocean to sequester heat and provide the long memory of the climate system. Understanding decadal variability requires the study of the generation of ocean anomalies at decadal frequencies, the evolution of oceanic signals, and the response of the atmosphere to oceanic perturbations. A sample of studies relevant for Pacific decadal variability will be reviewed in this presentation. The ocean integrates air-sea flux anomalies that result from internal atmospheric variability or broad-band coupled processes such as ENSO, or are an intrinsic part of the decadal feedback loop. Anomalies of Ekman pumping lead to deflections of the ocean thermocline and accompanying changes of the ocean circulation; perturbations of surface layer heat and fresh water budgets cause anomalies of T/S characteristics of water masses. The former process leads to decadal variability due to the dynamical adjustment of the mid latitude gyres or thermocline circulation; the latter accounts for the low frequency climate variations by the slow propagation of anomalies in the thermocline from the mid-latitude outcrops to the equatorial upwelling regions. Coupled modeling studies and ocean model hindcasts suggest that the adjustment of the North Pacific gyres to variation of Ekman pumping causes low frequency variations of surface temperature in the Kuroshio-Oyashio extension region. These changes appear predictable a few years in advance, and affect the local upper ocean heat budget and precipitation. The majority of low frequency variance is explained by the ocean's response to stochastic atmospheric forcing, the additional variance explained by mid-latitude ocean to atmosphere feedbacks appears to be small. The coupling of subtropical and tropical regions by the equator-ward motion in the thermocline can support decadal anomalies by changes of its speed and path, or by transporting water mass anomalies to the equatorial

    The optical variability of 29 flat spectrum radio quasars in SDSS Stripe 82 region are investigated by using DR7 released multi-epoch data. All FSRQs show variations with overall amplitude ranging from 0.24 mag to 3.46 mag in different sources. About half of FSRQs show a bluer-when-brighter trend, which is commonly observed for blazars. However, only one source shows a redder-when-brighter trend, which implies it is rare in FSRQs. In this source, the thermal emission may be responsible for the spectral behaviour.

    We introduce a new class of jet algorithms designed to return conical jets with a variable Delta R radius. A specific example, in which Delta R scales as 1/pT, proves particularly useful in capturing the kinematic features of a wide variety of hard scattering processes. We implement this Delta R scaling in a sequential recombination algorithm and test it by reconstructing resonance masses and kinematic endpoints. These test cases show 10-20% improvements in signal efficiency compared to fixed Delta R algorithms. We also comment on cuts useful in reducing continuum jet backgrounds.

  16. Solar Irradiance Variability

    CERN Document Server

    Solanki, Sami K

    2012-01-01

    The Sun has long been considered a constant star, to the extent that its total irradiance was termed the solar constant. It required radiometers in space to detect the small variations in solar irradiance on timescales of the solar rotation and the solar cycle. A part of the difficulty is that there are no other constant natural daytime sources to which the Sun's brightness can be compared. The discovery of solar irradiance variability rekindled a long-running discussion on how strongly the Sun affects our climate. A non-negligible influence is suggested by correlation studies between solar variability and climate indicators. The mechanism for solar irradiance variations that fits the observations best is that magnetic features at the solar surface, i.e. sunspots, faculae and the magnetic network, are responsible for almost all variations (although on short timescales convection and p-mode oscillations also contribute). In spite of significant progress important questions are still open. Thus there is a debat...

    Electromechanical variable capacitors, or varactors, find a wide range of applications including sensing applications and the tuning of electrical circuit resonance. We demonstrate a nano-electromechanical graphene varactor, a variable capacitor wherein the capacitance is tuned by voltage controlled deflection of a dense array of suspended graphene membranes. The low flexural rigidity of graphene monolayers is exploited to achieve low actuation voltage and high tunable capacitance density in an ultra-thin structure. Large arrays comprising thousands of suspensions were fabricated to give a tunable capacitance of over 10 pF mm-2. This capacitance density suggests that graphene offers a potential solution to the challenge of reducing the size of micro-electromechanical systems (MEMS). A capacitance tuning of 55% was achieved with a 10 V actuating voltage, exceeding the 50% tuning limit of Hookean parallel plate pull-in without the use of complex mechanical schemes that occupy substrate area. Capacitor behavior was investigated experimentally, and described by a simple theoretical model. Mechanical properties of the graphene membranes were measured independently using atomic force microscopy. We present a comparison of state-of-the-art MEMS and graphene varactors. The quality factor of graphene varactors is limited by graphene sheet resistance, pull-in voltage can be improved with more aggressive scaling, while the power handling and cycling stability of graphene varactors remains unknown.

    The shape of liquid interfaces can be precisely controlled using electrowetting,an actuation mechanism which has been widely used for tunable optofluidic micro-optical components such as lenses or irises.We have expanded the considerable flexibility inherent in electrowetting actuation to realize a variable optofluidic slit,a tunable and reconfigurable two-dimensional aperture with no mechanically moving parts.This optofluidic slit is formed by precisely controlled movement of the liquid interfaces of two highly opaque ink droplets.The 1.5 mm long slit aperture,with controllably variable discrete widths down to 45 μm,may be scanned across a length of 1.5 mm with switching times between adjacent slit positions of less than 120 ms.In addition,for a fixed slit aperture position,the width may be tuned to a minimum of 3 μm with high uniformity and linearity over the entire slit length.This compact,purely fluidic device offers an electrically controlled aperture tuning range not achievable with extant mechanical alternatives of a similar size.

  19. Chatter Prediction for Variable Pitch and Variable Helix Milling

    2015-01-01

    Full Text Available Regenerative chatter is a self-excited vibration that can occur during milling, which shortens the lifetime of the tool and results in unacceptable surface quality. In this paper, an improved semidiscretization method for modeling and simulation with variable pitch and variable helix milling is proposed. Because the delay between each flute varies along the axial depth of the tool in milling, the cutting tool is discrete into some axial layers to simplify calculation. A comparison of the predicted and observed performance of variable pitch and variable helix against uniform pitch and uniform helix milling is presented. It is shown that variable pitch and variable helix milling can obtain larger stable cutting area than uniform pitch and uniform helix milling. Thus, it is concluded that variable pitch and variable helix milling are an effective way for suppressing chatter.

    This report details a new design for a variable speed controller which can be used to operate lunar machinery without the astronaut using his or her upper body. In order to demonstrate the design, a treadle for an industrial sewing machine was redesigned to be used by a standing operator. Since the invention of an electrically powered sewing machine, the operator has been seated. Today, companies are switching from sit down to stand up operation involving modular stations. The old treadle worked well with a sitting operator, but problems have been found when trying to use the same treadle with a standing operator. Emphasis is placed on the ease of use by the operator along with the ergonomics involved. Included with the design analysis are suggestions for possible uses for the speed controller in other applications.

    In this paper, we studied the three-echelon supply chain composed by a raw material supplier, an OEM and a manufacturer, where when the OEM was faced with funds constraint, the manufacturer would adopt the buy-and-sell mode to purchase raw materials from the supplier and was rewarded with a price discount due to the large volume of the purchase. It would then sell the materials purchased to the OEM and the accounts payable of both the OEM and the manufacturer were paid in deferral. Then we built the buy-and-sell based model and solved it to obtain the optimal ordering quantity of the manufacturer under this mode;next, by comparing the models with and without funds constraint when not adopting the buy-and-sell mode, we determined the extent of the deferred payment so that the profit of the manufacturer and the OEM was not less than that when there was funds constraint or not. The numerical analysis demonstrated that under the buy-and-sell mode, the profit of the supply chain system was larger than the expected profit in the classic newsboy model and that the mode could coordinate the supply chain.%考虑在由原料供应商、OEM及制造商构成的三级供应链中,OEM面临资金约束时,制造商采用Buy-and-Sell模式从原料供应商处采购原料,通过数量优势获得价格折扣,再转卖给OEM,OEM和制造商的应付款都延期支付。建立基于Buy-and-Sell模式的模型,求解该模式下制造商的最优订购量;并通过与不采用Buy-and-Sell模式时,无资金约束和资金约束下的模型进行对比,求解使制造商和OEM的利润均不低于资金约束情况下和无资金约束情况下利润的延期支付取值范围。数值分析表明:Buy-and-Sell模式下,供应链系统的利润大于在经典报童模型下的期望利润,该模式可以实现供应链协调。

Four processing modes of the silkworm eggs were single refrigeration and pickling, single refrigeration and no pickling, double refrigeration and pickling, double refrigeration and no pickling. Practical hatchability and newly-hatched silkworm life rate for fast 80 hours were the main focus in the survey. The results showed that the silkworm egg hatchability exhibited a downward trend with the increasing cold stor-age time. The hatchability of the no pickling processing mode was slightly higher than that of the pickling ones, and double refrigeration processing mode had higher hatchability than single refrigeration ones.

    Full Text Available Gait variability, that is, fluctuations in movement during walking, is an indicator of walking function and has been associated with various adverse outcomes such as falls. In this paper, current research concerning gait variability in persons with multiple sclerosis (MS is discussed. It is well established that persons with MS have greater gait variability compared to age and gender matched controls without MS. The reasons for the increase in gait variability are not completely understood. Evidence indicates that disability level, assistive device use, attentional requirement, and fatigue are related to gait variability in persons with MS. Future research should address the time-evolving structure (i.e., temporal characteristics of gait variability, the clinical importance of gait variability, and underlying mechanisms that drive gait variability in individuals with MS.

  8. Variable angle correlation spectroscopy

    Energy Technology Data Exchange (ETDEWEB)

    Lee, Y K [Univ. of California, Berkeley, CA (United States)

    1994-05-01

    In this dissertation, a novel nuclear magnetic resonance (NMR) technique, variable angle correlation spectroscopy (VACSY) is described and demonstrated with {sup 13}C nuclei in rapidly rotating samples. These experiments focus on one of the basic problems in solid state NMR: how to extract the wealth of information contained in the anisotropic component of the NMR signal while still maintaining spectral resolution. Analysis of the anisotropic spectral patterns from poly-crystalline systems reveal information concerning molecular structure and dynamics, yet in all but the simplest of systems, the overlap of spectral patterns from chemically distinct sites renders the spectral analysis difficult if not impossible. One solution to this problem is to perform multi-dimensional experiments where the high-resolution, isotropic spectrum in one dimension is correlated with the anisotropic spectral patterns in the other dimensions. The VACSY technique incorporates the angle between the spinner axis and the static magnetic field as an experimental parameter that may be incremented during the course of the experiment to help correlate the isotropic and anisotropic components of the spectrum. The two-dimensional version of the VACSY experiments is used to extract the chemical shift anisotropy tensor values from multi-site organic molecules, study molecular dynamics in the intermediate time regime, and to examine the ordering properties of partially oriented samples. The VACSY technique is then extended to three-dimensional experiments to study slow molecular reorientations in a multi-site polymer system.

    Full Text Available Altichiero was the dominant north Italian painter of the later Trecento. In Padua, in the 1370s and early 1380s, he worked for patrons close to Petrarch and his circle and perhaps in direct contact with the poet himself. By the time of the second edition of Vasari's Vite (1568 the memory of Altichiero's work had suffered significant occlusion, and Vasari's account of him is little more than an appendix to his life of Carpaccio. Only since the later nineteenth century, and particularly in the last fifty or so years, has Altichiero's reputation been restored. It is the purpose of this paper to examine aspects of that reputation throughout the century or so after the painter's death (by April 1393.

    Earth observations from space are one of the great successes of the space age. However, because the promise of this technology is a long way from being realized, the joy of success is tinged with disappointment for both researchers and operational users of the data. U.S. Earth observation programs have been in turmoil since their inception, with confusion coming to a crescendo over the past 6 years. Neither the executive or legislative branches of the government have shown that they can successfully manage this technological capability created by the space program.

    Full Text Available (Editorial preface. The publication is presented in order to remind us of one of dramatic pages of the history of genetics. It re-opens for the contemporary reader a comprehensive work marking the priority change from plant cytogenetics to animal cytogenetics led by wide population studies which were conducted on Drosophila polytene chromosomes. The year of the publication (1937 became the point of irretrievable branching between the directions of Old World and New World genetics connected with the problems of chromosome variability and its significance for the evolution of the species. The famous book of T. Dobzhansky (1937 was published by Columbia University in the US under the title “Genetics and the origin of species”, and in the shadow of this American ‘skybuilding’ all other works grew dim. It is remarkable that both Dobzhansky and Dubinin come to similar conclusions about the role of chromosomes in speciation. This is not surprising given that they both might be considered as representatives of the Russian genetic school, by their birth and education. Interestingly, Dobzhansky had never referred to the full paper of Dubinin et al. (1937, though a previous short communication in Nature (1936 was included together with all former papers on the related subject. In full, the volume of the original publication printed in the Biological Journal in Moscow comprised 47 pages, in that number 41 pages of the Russian text accompanied by 16 Figs, a table and reference list, and, above all, 6 pages of the English summary. This final part in English is now reproduced in the authors’ version with the only addition being the reference list in the originally printed form.

    2008-01-01

    The notion of meta-variable plays a fun-damental role when we define formal systems such as logical and computational calculi. Yet it has been usually understood only informally as is seen in most textbooks of logic. Based on our observations of the usages of meta-variables in textbooks, we propose two formal systems that have the notion of meta-variable. In both calculi, each variable is given a level (non-negative integer), which classifies variables into object variables (level 0), meta-variables (level 1), metameta-variables (level 2) and so on. Then, simple arity systems are. used to exclude meaningless terms like a meta-level function operating on the metameta-level. A main difference of the two calculi lies in the definitions of substitution. The first calculus uses textual substitution, which can often be found in definitions of quantified formulae: when a term is substituted for a meta-variable, free object-level variables in the term may be captured. The second cal-culus is based on the observation that predicates can be regarded as meta-level functions on object-level terms, hence uses capture-avoiding substitution. We show that both calculi enjoy a number of properties including Church-Rosser and Strong Normalization, which are indispensable when we use them as frameworks to define logical systems.

  1. An Efficient Q2P1 Finite Element Discretisation and Preconditioner for Variable Viscosity Stokes Systems

    Science.gov (United States)

    May, Dave; Le Pourhiet, Laetitia; Brown, Jed

    2014-05-01

    Here I describe a numerical method suitable for studying 3D non-linear, large deformation processes associated with crustal and lithopspheric deformation. The method employs a combination of mixed finite elements for the flow problem, coupled to the Material-Point-Method for representing material state and history variables. This computational methodology is intended to simultaneously satisfy all of the geodynamic modelling requirements. Particular emphasis is given to the development of non-linear solvers and preconditioners which are performant, practical and highly scalable - thereby enabling high resolution 3D simulations to be performed using massively parallel computational hardware. We have made a number of fundamental design choices which result in a fast, highly scalable and robust Q2P1 finite element implementation which is suitable for solving a wide range of geodynamic applications. Specifically these choices include: (i) utilizing an inf-sup stable mixed finite element (with a mapped pressure space) which provides a reliable velocity and pressure solution; (ii) expressing the problem in defect correction form so that Newton-like methods can be exploited; (iii) making extensive use of matrix-free operators which both drastically reduces the memory requirements and improves the parallel scalability of the sparse matrix-vector product; (iv) deferring a wide range of choices associated with the solver configuration to run-time. The performance characteristics of our hybrid geometric multi-grid preconditioning strategy is presented. The robustness of the preconditioner with respect to the viscosity contrast and the topology of the viscosity field, together with the parallel scalability is demonstrated. We will highlight the benefits of using hybrid coarse grid hierarchies consisting of a combination of Galerkin, assembled and matrix-free operators. The merits of using aggressive coarsening strategies will also be discussed. Examples from 3D continental

    Full Text Available There are two kinds of annuity, annuity certain and life annuity. Annuity certain does not depend on life probability, for example, mortgage. Life annuity depends on time until death and life probability, for example, pension payment from insurance company. The objective of this paper is to discuss further about life annuity and the relationship with life probability that is influences by time until death and the assumption of interest which is used. Time until death (T is a random variable, because it is unpredictable. To determine the value of distribution, assumption values on tqx will be used. These values are generated by T simulation which depends on Uniform distribution (0,1 random values. A few cases of determining life annuity using tpx distribution values by T simulation will be discussed.

  3. Variable Sampling Mapping

    Smith, Jeffrey, S.; Aronstein, David L.; Dean, Bruce H.; Lyon, Richard G.

    2012-01-01

    The performance of an optical system (for example, a telescope) is limited by the misalignments and manufacturing imperfections of the optical elements in the system. The impact of these misalignments and imperfections can be quantified by the phase variations imparted on light traveling through the system. Phase retrieval is a methodology for determining these variations. Phase retrieval uses images taken with the optical system and using a light source of known shape and characteristics. Unlike interferometric methods, which require an optical reference for comparison, and unlike Shack-Hartmann wavefront sensors that require special optical hardware at the optical system's exit pupil, phase retrieval is an in situ, image-based method for determining the phase variations of light at the system s exit pupil. Phase retrieval can be used both as an optical metrology tool (during fabrication of optical surfaces and assembly of optical systems) and as a sensor used in active, closed-loop control of an optical system, to optimize performance. One class of phase-retrieval algorithms is the iterative transform algorithm (ITA). ITAs estimate the phase variations by iteratively enforcing known constraints in the exit pupil and at the detector, determined from modeled or measured data. The Variable Sampling Mapping (VSM) technique is a new method for enforcing these constraints in ITAs. VSM is an open framework for addressing a wide range of issues that have previously been considered detrimental to high-accuracy phase retrieval, including undersampled images, broadband illumination, images taken at or near best focus, chromatic aberrations, jitter or vibration of the optical system or detector, and dead or noisy detector pixels. The VSM is a model-to-data mapping procedure. In VSM, fully sampled electric fields at multiple wavelengths are modeled inside the phase-retrieval algorithm, and then these fields are mapped to intensities on the light detector, using the properties

  4. MODELING SUPPLY CHAIN PERFORMANCE VARIABLES

    Ashish Agarwal

    2005-01-01

    Full Text Available In order to understand the dynamic behavior of the variables that can play a major role in the performance improvement in a supply chain, a System Dynamics-based model is proposed. The model provides an effective framework for analyzing different variables affecting supply chain performance. Among different variables, a causal relationship among different variables has been identified. Variables emanating from performance measures such as gaps in customer satisfaction, cost minimization, lead-time reduction, service level improvement and quality improvement have been identified as goal-seeking loops. The proposed System Dynamics-based model analyzes the affect of dynamic behavior of variables for a period of 10 years on performance of case supply chain in auto business.

    Variable selection is important in QSAR modeling since it can improve model performance and transparency, as well as reduce the computational cost of model fitting and predictions. Which variable selection methods that perform well in QSAR settings is largely unknown. To address this question we, in a total of 1728 benchmarking experiments, rigorously investigated how eight variable selection methods affect the predictive performance and transparency of random forest models fitted to seven QSAR datasets covering different endpoints, descriptors sets, types of response variables, and number of chemical compounds. The results show that univariate variable selection methods are suboptimal and that the number of variables in the benchmarked datasets can be reduced with about 60 % without significant loss in model performance when using multivariate adaptive regression splines MARS and forward selection.

    By means of a population synthesis code, we investigate the Mira variables. Their birth rate (over 0.65yr-1) and their number (~ 130000) in the Galaxy are estimated. For all possible Mira variables, ranges of their initial masses,pulsating periods, mass losses and lifetimes are given. We check our model with the observed Mira variables near the Sun and our results prove to be valid.

    We aim to construct an exceptionally deep (V ≲ 27) catalog of variable objects in selected Galactic and extragalactic fields visited multiple times by the Hubble Space Telescope (HST). While HST observations of some of these fields were searched for specific types of variables before (most notably, the extragalactic Cepheids), we attempt a systematic study of the population of variable objects of all types at the magnitude range not easily accessible with ground-based telescopes. The variability timescales that can be probed range from hours to years depending on how often a particular field has been visited. For source extraction and cross-matching of sources between visits we rely on the Hubble Source Catalog which includes 107 objects detected with WFPC2, ACS, and WFC3 HST instruments. The lightcurves extracted from the HSC are corrected for systematic effects by applying local zero-point corrections and are screened for bad measurements. For each lightcurve we compute variability indices sensitive to a broad range of variability types. The indices characterize the overall lightcurve scatter and smoothness. Candidate variables are selected as having variability index values significantly higher than expected for objects of similar brightness in the given set of observations. The Hubble Catalog of Variables will be released in 2018.

    Full Text Available Abstract Acceptable random variables introduced by Giuliano Antonini et al. (J. Math. Anal. Appl. 338:1188-1203, 2008 form a class of dependent random variables that contains negatively dependent random variables as a particular case. The concept of acceptability has been studied by authors under various versions of the definition, such as extended acceptability or wide acceptability. In this paper, we combine the concept of acceptability with the concept of conditioning, which has been the subject of current research activity. For conditionally acceptable random variables, we provide a number of probability inequalities that can be used to obtain asymptotic results.

    Full Text Available Foi realizado um experimento no Departamento de Zootecnia da UFSM, Santa Maria, RS, Brasil, com o objetivo de estimar os efeitos do fogo associado ao pastejo, com ou sem período de diferimento após a queima, sobre o resíduo e mesofauna edáfica de uma pastagem natural. Foi observada, também, o efeito do fogo sobre a variação da temperatura do solo. O experimento foi instalado no inverno de 1992 e os dados foram coletados no período de maio de 1993 a junho de 1994. Os tratamentos foram: queimado em 17/09/92 e Rastejado; queimado em 17/09/92, diferido, requeimado em 05/09/93 e pastejado; não queimado e pastejado em 1992, queimado em 22/06/93 e diferido. Foi constatado que o fogo diminui o resíduo da pastagem e essa redução é maior ainda quando há pastejo. Não foram observadas alterações significativas na temperatura do solo, devido à intensidade do fogo ter sido baixa. A queima e o pastejo não apresentaram efeitos significativos sobre a população de colêmbolos e ácaros do solo.This study was carried out to evaluate the effects of burning associated with grazing and burning with deferring periods, on residual dry matter, soil temperature and mesofauna composition of a natural pasture. The experiment was conducted at the Animal Science Departament, UFSM, Santa Maria, RS, Brasil. The trial was initiated in the Winter of 1992 and data were collected from May, 1993 to June, 1994. Treatments consisted of: burned in 9/17/92 and grazed: burned in 9/17/92 and deferred, reburned in 9/5/93 and grazed; not burned in 1992 and grazed, burned in 6/22/93 and deferred. Burning reduced dry matter residue and the reduction was more pronounced when burning was followed by grazing. Soil temperature was not affected by burning mainly because its intensity was low. Soil mesofauna was not significantiy affected by the diffèrent treatments tested.

    Variability of large scale wind power generation is dependent on several factors: characteristics of installed wind power plants, size of the area where the plants are installed, geographic dispersion within that area and its weather regime(s). Variability can be described by ramps in power generation, i.e. changes from time period to time period. Given enough data points, it can be described with a probability density function. This approach focuses on two dimensions of variability: duration of the ramp and probability distribution. This paper proposes an index based on these two dimensions to enable comparisons and characterizations of variability under different conditions. The index is tested with real, large scale wind power generation data from several countries. Considerations while forming an index are discussed, as well as the main results regarding what the drivers of variability experienced for different data.

    The heart rate variability is a useful method to assess cardiac autonomic modulation in patients undergoing dental procedures, because knowledge of physiological conditions provides greater security to the professional as well as the possibility of a better plan treatment to patient benefit. The aim of our study was to describe the association between cardiac autonomic control and dental variables. We consulted the databases Medline, SciELO, Lilacs and Cochrane, using the terms "autonomic", "dentistry", "heart rate variability", "cardiovascular physiology." The selected studies indicated a strong relationship between dental variables and HRV. There was an association between malocclusion, TMD, dental procedures cirugia and low HRV. Thus, they become more studies that relate to HRV in dental science, especially in clinical practice.

I have calculated fits for two variability parameters (amplitude and characteristic timescale) for these objects using maximum likelihood statistics. The list is being probed for violent variability, as from BL Lac Objects and OVVs. Knowledge of these objects' parameters will help separate their contribution in the microwave from that of the CMB when the equatorial Stripe 82 is eventually observed with the Atacama Cosmology Telescope.

    With recent developments in imaging and computer technology the amount of available astronomical data has increased dramatically. Although most of these data sets are not dedicated to the study of variable stars much of it can, with the application of proper software tools, be recycled for the discovery of new variable stars. Fits Viewer and Data Retrieval System is a new software package that takes advantage of modern computer advances to search astronomical data for new variable stars. More than 200 new variable stars have been found in a data set taken with the Calvin College Rehoboth Robotic telescope using FVDRS. One particularly interesting example is a very fast subdwarf B with a 95 minute orbital period, the fastest currently known of the HW Vir type.

    Variations in solar activity, as revealed by variations in the number of sunspots, have been observed since ancient times. To what extent changes in the solar output may affect planetary climates, though, remains today more than ever a subject of controversy. In 2000, the SSSI volume on Solar Variability and Climate reviewed the to-date understanding of the physics of solar variability and of the associated climate response. The present volume on Solar Variability and Planetary Climates provides an overview of recent advances in this field, with particular focus at the Earth's middle and lower atmosphere. The book structure mirrors that of the ISSI workshop held in Bern in June 2005, the collection of invited workshop contributions and of complementary introductory papers synthesizing the current understanding in key research areas such as middle atmospheric processes, stratosphere-troposphere dynamical coupling, tropospheric aerosols chemistry, solar storm influences, solar variability physics, and terrestri...

    Variability within perioperative services has come to be something physicians, perioperative nurses, and managers expect. Peaks and valleys in schedules; differences in physician preferences for surgical implants, instruments, and supplies; staffing competencies; and inpatient bed availability are just a few examples of day-to-day variability that affects perioperative services personnel. Rather than simply responding to variability, however, the goal should be to eliminate variability in patient flow as much as possible and effectively manage what cannot be eliminated. Combining the hard science of queuing theory and simulation modeling with the soft science of change management and operations improvement expertise is the key to success, and a collaborative team makes it possible.

  10. Investigation of load reduction for a variable speed, variable pitch, and variable coning wind turbine

    1997-12-31

    A two bladed, variable speed and variable pitch wind turbine was modeled using ADAMS{reg_sign} to evaluate load reduction abilities of a variable coning configuration as compared to a teetered rotor, and also to evaluate control methods. The basic dynamic behavior of the variable coning turbine was investigated and compared to the teetered rotor under constant wind conditions as well as turbulent wind conditions. Results indicate the variable coning rotor has larger flap oscillation amplitudes and much lower root flap bending moments than the teetered rotor. Three methods of control were evaluated for turbulent wind simulations. These were a standard IPD control method, a generalized predictive control method, and a bias estimate control method. Each control method was evaluated for both the variable coning configuration and the teetered configuration. The ability of the different control methods to maintain the rotor speed near the desired set point is evaluated from the RMS error of rotor speed. The activity of the control system is evaluated from cycles per second of the blade pitch angle. All three of the methods were found to produce similar results for the variable coning rotor and the teetered rotor, as well as similar results to each other.

We show the application of the proposed approach on several Kuramoto systems, in particular one living on networks built by preferential attachment and a model for the transition from deeply to lightly anaesthetized states. Granger causalities describe the flow of information among variables.

    The authors present an observational and theoretical review of the winds of cataclysmic variables (CVs). Specifically, they consider the related problems of the geometry and mass-loss rate of the winds of CVs, their ionization state and variability, and the results from studies of eclipsing CVs. Finally, they consider the properties of accretion disk wind models. Some of these models predict substantial angular momentum loss, which could affect both disk structure and binary evolution.

  14. Dark Matter with Variable Masses

    Science.gov (United States)

    García-Bellido, Juan

    String effective theories contain a dilaton scalar field which couples to gravity, matter and radiation. In general, particle masses will have different dilaton couplings. We can always choose a conformal frame in which baryons have constant masses while (nonbaryonic) dark matter have variable masses, in the context of a scalar-tensor gravity theory. We are interested in the phenomenology of this scenario. Dark matter with variable masses could have a measurable effect on the dynamical motion of the halo of spiral galaxies, which may affect cold dark matter models of galaxy formation. As a consequence of variable masses, the energy-momentum tensor is not conserved; there is a dissipative effect, due to the dilaton coupling, associated with a “dark entropy” production. In particular, if axions had variable masses they could be diluted away, thus opening the “axion window.” Assuming that dark matter with variable masses dominates the cosmological evolution during the matter era, it will affect the primordial nucleosynthesis predictions on the abundances of light elements. Furthermore, the dilaton also couples to radiation in the form of a variable gauge coupling. Experimental bounds will constrain the parameters of this model.

    Full Text Available Atmospheric variables, which represent meteorology if seen in their instantaneous behavior or climatology if seen in their long time behavior, can be considered among the main driving variables of agricultural and forest ecosystems. In other words meteo-climatic variables determine productivity and quality and territorial specificity of agroforestry productions. On the base of this premise some significant examples are shown in order to describe how different modeling approaches (empirical and mechanistic can improve our degree of description of phenomena and the rationality of our approach to management of agro-ecosystem. The need of strict linkage among agrometeorology and other physical and biological sciences referred to agro-forestry ecosystems is also discussed.

    Nonlinear phenomena in science and engineering such as a periodically forced oscillator with nonlinear elasticity are often modeled by the Duffing oscillator (Duffing equation). The Duffling oscillator is a type of nonlinear higher order differential equation. In this research, a numerical approximation for solving the Duffing oscillator directly is introduced using a variable order stepsize (VOS) algorithm coupled with a backward difference formulation. By selecting the appropriate restrictions, the VOS algorithm provides a cost efficient computational code without affecting its accuracy. Numerical results have demonstrated the advantages of a variable order stepsize algorithm over conventional methods in terms of total steps and accuracy.

  18. Monitoring Variability of the Sky

    CERN Document Server

    Paczynski, B

    2001-01-01

    Variability in the sky has been known for centuries, even millennia, but our knowledge of it is very incomplete even at the bright end. Current technology makes it possible to built small, robotic optical instruments, to record images and to process data in real time, and to archive them on-line, all at a low cost. In addition to obtaining complete catalogs of all kinds of variable objects, spectacular discoveries can be made, like the optical flash associated with GRB 990123 and a planetary transit in front of HD 209458. While prototypes of such robotic instruments have been in operation for several years, it is not possible to purchase a complete system at this time. I expect (hope) that complete systems will become available `off the shelf' in the near future, as monitoring bright sky for variability has a great scientific, educational and public outreach potential.

  19. Time as a dynamical variable

    Science.gov (United States)

    Thron, Christopher

    2017-01-01

    Since the time of Galileo, the equations of physics have expressed dynamical variables such as particle position or electromagnetic field strength as functions of time. In this paper, we argue that this assumption reflects observational bias, and that there are many good reasons for viewing time also as a dynamical variable. We hypothesize that the spacetime universe is an outcome of a process, rather than a process unfolding in time. This new viewpoint gives rise to a physical interpretation of the wavefunction as a complex vibrational amplitude in a non-spacetime independent variable. It resolves quantum mechanical paradoxes involving wavefunction entanglement, and gives a much simpler solution to the problem of wavefunction collapse than the many-worlds interpretation. The Born rule is also shown to be a natural consequence. We also show that small deviations from conventional quantum probabilities are predicted.

  20. Fourier Analysis of Blazar Variability

    CERN Document Server

    Finke, Justin D

    2014-01-01

    Blazars display strong variability on multiple timescales and in multiple radiation bands. Their variability is often characterized by power spectral densities (PSDs) and time lags plotted as functions of the Fourier frequency. We develop a new theoretical model based on the analysis of the electron transport (continuity) equation, carried out in the Fourier domain. The continuity equation includes electron cooling and escape, and a derivation of the emission properties includes light travel time effects associated with a radiating blob in a relativistic jet. The model successfully reproduces the general shapes of the observed PSDs and predicts specific PSD and time lag behaviors associated with variability in the synchrotron, synchrotron self-Compton (SSC), and external Compton (EC) emission components, from sub-mm to gamma-rays. We discuss applications to BL Lacertae objects and to flat-spectrum radio quasars (FSRQs), where there are hints that some of the predicted features have already been observed. We a...
