ON-BOARD AND PRE-FLIGHT MECHANICAL MODEL OF YURCHENKO ONE TWIST ON VAULT: IMPLICATIONS FOR PERFORMANCE

The aim of this study was to point out the biomechanical explanation of the judges’ detection of scores relative to the on-board and pre-flight phases of the Yurchenko vault with one twist on (table). In an attempt to identify the weakness of technique and then to diagnose the likely causes of a poor performance, an extensive analysis was undertaken using a deterministic model. The 4 female gymnasts performing YU vault one twist on during the 2006 Italian Championship for Clubs were filmed by three cameras operating at 100Hz. Spearman’s correlation coefficient was used to establish the strength of the relationship between the mechanical variables of the model and the judges` detection of points. Significant correlations indicated that the loss of credit depended mostly on angular variables. Firstly, low angular velocity of the center of mass (CM) at the impact of the board, then the small angular displacement of CM and high shoulder angular velocity produced on board and finally, a smaller hip extension and a larger shoulders extension at the take off from the board. In addition, other vertical variables determined a worst result: the lack of height of the CM at takeoff from the board, the decreased displacement of the CM on the board and the loss of the vertical velocity on the board.
Poverty and Support for Artists

Hans Abbing In our society the value of art is high and yet the majority of artists are poor. Not only the is symbolic value of art high, often the financial value is high as well. People and institutions are prepared to pay high prices for artworks and performances, and governments and foundations spend huge amounts on prestigious new museums and concert halls. But the typical artist is poor. This sharp and paradoxical contrast can be explained: the low incomes are the consequence of the high symbolic value of art. This implies that poverty in the arts is largely structural. Subsidies intended to raise artists’ incomes tend to be futile and can easily be counter-productive.
Kirillov’s orbit method and polynomiality of the faithful dimension of $p$ -groups

Given a finite group $\text{G}$ and a field $K$ , the faithful dimension of $\text{G}$ over $K$ is defined to be the smallest integer $n$ such that $\text{G}$ embeds into $\operatorname{GL}_{n}(K)$ . We address the problem of determining the faithful dimension of a $p$ -group of the form $\mathscr{G}_{q}:=\exp (\mathfrak{g}\otimes _{\mathbb{Z}}\mathbb{F}_{q})$ associated to $\mathfrak{g}_{q}:=\mathfrak{g}\otimes _{\mathbb{Z}}\mathbb{F}_{q}$ in the Lazard correspondence, where $\mathfrak{g}$ is a nilpotent $\mathbb{Z}$ -Lie algebra which is finitely generated as an abelian group. We show that in general the faithful dimension of $\mathscr{G}_{p}$ is a piecewise polynomial function of $p$ on a partition of primes into Frobenius sets. Furthermore, we prove that for $p$ sufficiently large, there exists a partition of $\mathbb{N}$ by sets from the Boolean algebra generated by arithmetic progressions, such that on each part the faithful dimension of $\mathscr{G}_{q}$ for $q:=p^{f}$ is equal to $fg(p^{f})$ for a polynomial $g(T)$ . We show that for many naturally arising $p$ -groups, including a vast class of groups defined by partial orders, the faithful dimension is given by a single formula of the latter form. The arguments rely on various tools from number theory, model theory, combinatorics and Lie theory.
Feedback solutions to dynamic models of optimal taxation

The problem of dynamic optimal taxation is one of the important issues in macroeconomics and public flnance theory. In their in∞uential studies Chamley [1] and Judd [2] establish that the optimal tax on capital income should be zero in the long run. This somewhat surprising result has been derived as an open-loop Stackelberg solution of a dynamic game using necessary conditions for optimality. In this paper we show that the optimal capital tax can be difierent from zero whenever the solution of the dynamic taxation problem is considered in the class of state-feedback controls. Under suitable assumptions we also show that the feedback Nash equilibria for the models proposed by Chamley and Judd can be computed explicitly. The same approach can be applied to a slightly generalized version of the model considered in [3]. Finally, we present some illustrative examples.

PRESCRIBING WRITING ERRORS IN FAMILY HEALTH UNITS IN ZAGAZIG CITY: A COMPARATIVE STUDY BETWEEN ACCREDITED AND NON-ACCREDITED HEALTH UNITS

Objective:In this study, the main objective was to determine prescription errors in family health units in Zagazig city accredited versus non accredited and its relation to the organizational climate. Patients &Method:10 accredited family health units were included in the study. Comparing the prescription of these unit to the standard of the ministry of health and WHO. Results:. It was found that the frequency of errors in accredited unit were fewer. The accreditation affects both the frequency of errors and the organizational climate, as the accredited units showed fewer errors and higher organizational climate score than the non-accredited units. There was a negative correlation between the organizational climate and the frequency of missing errors. Conclusions: Prescribers could be helped by designing systems to reduce the risk of these errors like that of a continuous education training programs and use of computerized prescription. The prescriptions need more effort and support from all the related to it; from the doctors, senior managers to the accreditation committee and ministry of health.
Education stakeholder’s constraints in policy decisions for effective policy implementation in Nigeria

Stakeholder’s participation in policy decisions and implementation was identified as an effective mechanism of ensuring educational quality and development.Through literature and document review this paper is aimed at identifying the factors that impede effective stakeholder participation in the implementation of education policies despite the fact that the National Education Policy has guaranteed their participation with a view to eliminating overlaps, sustain and achieve synergy. Among the identified issues that hinders their effective engagement include sidelining them in educational matters, politicizing education policies and delay in making decisions in cases of their involvement such as the School Based Management Committees (SBMC’s) and the Parent Teacher’s Association (PTA). To rectify the challenges towards achieving the goals of education, it is recommended that the government should partner with the stakeholders in education provision, involve them in all education related issues even in cases of policy revision; intensify enlightment campaigns about government policies & that the differences among the stakeholder should be accommodated as this is believed to ensure effective implementation of the policies.

Identification of Microblog Opinion Leaders based on User Features and Outbreak Nodes

At present, recognition of micro-blog opinion leaders mainly depends on the number of users posting micro-blogs, registration time, the number of good friends and other static attributes. However, it is very difficult to obtain the ideal recognition results through the above mentioned methods. This paper puts forward a new method that identifies the opinion leaders according to the change of user features and outbreak nodes. Deeply analyzing various attributes and behaviors of users, on the basis of user features and outbreak nodes, user’s attribute features are regarded as the input variables, behavior features of the user and outbreak nodes are regarded as observed variables. The probability as an opinion leader is the latent variable between input variables and observation variables, and the constructed probability model is used to recognize micro-blog opinion leaders. Experiments are carried out on the two real-world datasets from Sina micro-blog and Twitter, and the comparative experimental results show that the proposed model can more precisely find the micro-blog opinion leaders. Keywords—Micro-blog, Opinion leaders, User features, Influence strength, Outbreak nodes
An Integrated Scheme for Multilayer Network Restoration

An integrated multilayer resilience scheme rep- resents an efficient solution for guaranteeing resilience of peer-to-peer network architectures featuring a unified con- trol plane, such as the emerging IP/GMPLS/WDM architec- ture. In this study a single integrated multilayer restora- tion scheme, namely the Stochastic Integrated Multilayer Restoration (SIMuR) scheme, is proposed. The SIMuR scheme stochastically chooses, based on the current network status information, along which path and at which layer, i.e., granu- larity, failed lightpaths are restored. Simulation results show that the SIMuR scheme quickly approaches, for increasing granularity, the average restoration probability lower bound while limiting the required grooming and signaling overheads. Keywords— Resilience, Multilayer restoration, GMPLS.
Assessing the influence of inter-individual variability on the pharmacokinetics of environmental chemicals using PBPK modeling

Physiologically based pharmacokinetic (PBPK) models' ambition is to describe precisely the mechanisms of absorption, distribution, metabolism and elimination of chemicals in and out of the body. Their relative success at inter-species or inter-route extrapolation and prediction of inter-individual susceptibility is the main reason of their fame. Obviously, there is no set limit to their complexity and Occam's razor gets duller when only computing power shapes cutting edge research. The appeal of fast throughput has led to the development of large models with complex structure, probably too complex for most substances, but versatile. The PBPK models on the market are now able to screen many substances without having to make a costly investment in human intelligence and parsimony. The increasing complexity of PBPK models is not so much due to changes in their fundamental structure (they are still compartmental models) than to the addition of multiple ancillary models such as quantitative structureproperty relationships (QSPR) and parameter databases. QSPR models render them "substance-independent" and databases "subject-independent": A significant part of inter-individual variability and susceptibility to toxicity can be ascribed to known differences in pharmacokinetic parameters between sexes, ages, ethnic origins, physiological or pathological states. Monte Carlo sampling of these databases simulates mixed populations in which "susceptible" individuals can be studied to identify the particular parameter configurations at the origin of their singular pharmacokinetic behaviour (Jamei et al. 2009). That is an a priori approach, going forward from "first principles". It is useful, however, to be able to identify factors leading to susceptibility from population studies, as in the population pharmacokinetic approach. Such a posteriori observation-driven studies require much more sophisticated statistical analyses. So far, Bayesian numerical tools, such as Markov chain Monte Carlo simulations, are the best way to integrate the data collected together with the un-ignorable prior knowledge on human physiology in the context of complex models (Mezzetti et al., 2003). A current challenge, both in PBPK model structure and parameterisation, is to estimate and predict the part of susceptibility due to pharmacokinetic, metabolic or pharmacodynamic interactions between the substances we are exposed to through food, medical treatment, work, or lifestyle . Traditional modelling approaches and concepts meet their match here, and we may need to turn to the new arsenal of systems biology (Bois, 2010).
Grelina en regulación del apetito y papel en obesidad y trastornos alimentarios: Abordajes terapéuticos

Ghrelin is a peptide hormone secreted by the stomach. It was initially described as a stimulant of growth hormone secretion. Soon, however, it was discovered to play an important role in feeding behaviour in animals and in appetite regulation in man: ghrelin stimulates appetite, and as such is an orexigenic peptide implicated in energy balance mechanisms and weight gain. Abnormal ghrelin activity leads to over- or underweight. Additionally, the efficacy of different treatment strategies against obesity seems to be related to modifications in plasma ghrelin levels. Whereas the effects of ghrelin in the regulation of appetite, food intake and energy homeostasis have been fairly well documented, the pathways responsible for the effects of ghrelin are now increasingly being understood. As a consequence, clinical applications of ghrelin are now being developed. The purpose of this review is to provide updated information on the role of ghrelin in food intake and energy homeostasis, and on its mechanism of action. Moreover, the potential of ghrelin as a target for drugs to treat cachexia and obesity will be discussed.
Trophic ecology of the Endangered Darwin’s frog inferred by stable isotopes

Darwin’s frogs Rhinoderma spp. are the only known mouth-brooding frogs on Earth. The southern Darwin’s frog, R. darwinii, is found in the temperate forests of southern South America, is listed as Endangered and could be the only extant representative of this genus. Based on stomach contents, invertebrate prey availability and stable isotope analysis, we determined for the first time trophic ecological parameters for this species. Our results showed that R. darwinii is a generalist sit-and-wait predator and a secondary consumer, with a trophic position of 2.9. Carbon and nitrogen isotope composition indicated that herbivore invertebrates are their main prey, detected in 68.1% of their assimilated food. The most consumed prey included mosquitoes, flies, crickets, grasshoppers and ants. Detritivore and carnivore invertebrates were also ingested, but in lower proportions. Our results contribute to a better understanding of the feeding habits of this fully terrestrial amphibian and provide the first insight into their role linking low forest trophic positions with intermediate predators. We provide valuable biological information for in situ and ex situ conservation which can be used when developing habitat protection, reintroduction and captive breeding programmes. As revealed here, stable isotope analysis is a valuable tool to study the trophic ecology of highly endangered and cryptic species.
COST Action 272 “ Packet-Oriented Service Delivery via Satellite ” Two – State CDMA Receiver for Shared Uplink Satellite Channel TD-02-003-P

Most of future packet satellite systems are characterized by an high speed downlink channel broadcasted from the earth service gateway and a shared, low speed, return channel from each user equipment. In this paper a CDMA technique is proposed for return channel access mechanism. CDMA is interference limited rather than noise limited. The research for new methods to reduce interference and increase efficiency lead us to formulate a signaling method where fast impulsive silence states are mapped on zero-energy symbols. The theoretical formulation of the optimum receiver is reported and the probability of error for a generic linear CDMA receiver is derived. In particular, conventional and decorrelating two-states CDMA detector probability of errors are calculated. Numerical comparisons between two-states and traditional one-state CDMA conventional receivers are reported in the paper. Keywords—CDMA System Performance, System Capacity Analysis and Optimization, Receiver and Transmitter Design, Signal Processing Applications in Telecommunications, Multiple Access Techniques.
Software Reliability Control using Statistical Usage Testing

Software reliability is a frequently used term, but very seldom the reliability is under control, at least not in quantitative terms, during a software development project. This paper outlines a method, Statistical Usage Testing (SUT), which provides the opportunity to estimate and predict, and hence control software reliability. SUT is the reliability certification method described as a part of Cleanroom software engineering. The main objective of SUT is to certify the software reliability and to find the faults with high influence on reliability. SUT provides statistically based stopping rules during test as well as an effective use of test resources, which is shown by practical application of this and similar methods. This paper presents the basic ideas behind SUT and some of the current research being conducted in this area at the department of Communication Systems.
Bireference Procedure fBIP for Interactive Multicriteria Optimization with Fuzzy Coefficients

In the paper an approach to decision making in situations with non-pointlike characterisation and subjective evaluation of the actions is considered. The decision situation is represented mathematically as fuzzy multiobjective linear programming (fMOLP) model, where we apply the reduced fuzzy matrices instead of fuzzy classical numbers. The fMOLP model with reduced parameters is decomposable into the set of point-like models and the point-like models enable effective construction of an optimisation procedure - fBIP, see Wojewnik (2006ab), extending the bireference procedure by Michalowski and Szapiro (1992). The approach is applied to a fuzzy optimization problem in the area of telecommunication services.
Detecting antiferromagnetism of atoms in an optical lattice via optical Bragg scattering

Antiferromagnetism of ultracold fermions in an optical lattice can be detected by Bragg diffraction of light, in analogy to the diffraction of neutrons from solid-state materials. A finite sublattice magnetization will lead to a Bragg peak from the ((1/2)(1/2)(1/2)) crystal plane with an intensity depending on details of the atomic states, the frequency and polarization of the probe beam, the direction and magnitude of the sublattice magnetization, and the finite optical density of the sample. Accounting for these effects we make quantitative predictions about the scattering intensity and find that with experimentally feasible parameters the signal can be readily measured with a CCD camera or a photodiode and used to detect antiferromagnetic order.
Multitude potential of wheatgrass juice (Green Blood): An overview

Wheatgrass is the young grass of the common wheat plant Triticum aestivum Linn. , family Poeaceae (Graminae). It is commonly known as the "green blood" due to its high chlorophyll content which accounts for 70% of its chemical constituents. It contains a plethora of vitamins, minerals, amino acids and vital enzymes like superoxide dismutase and cytochrome oxidase. The vitamin content makes it an important adjuvant in anti-allergic and anti-asthmatic treatment, while the enzymes play a pivotal role in the anticancer approach of this herbal drug. A notable feature of the wheatgrass juice is its bioflavonoid content which are the naturally occurring antioxidants and ac­count for many of its clinical utilities such as management of inflammatory bowel disease and as a general detoxi-fier. However, the most remarkable feature of the wheatgrass juice is its high chlorophyll content. Chlorophyll bears structural similarity to hemoglobin and has been found to regenerate or act as a substitute of hemoglobin in hemoglobin deficiency conditions. This might be the reason behind the utility of wheatgrass in clinical conditions like thalassemia and hemolytic anemia. The present article focuses onto the various studies emphasizing the multi­tude potentials of wheatgrass.
DD No . 14 / 04 Don ’ t Stop ’ Til You Get Enough : a quickest detection approach to HTA

Within the context of the value of information approach we compare static versus quickest detection rules for research design in health care technology assessment (HTA). We show for a research design that the optimal decision rule cannot be correctly predicted at the start of the trial. We make use of the sequential value of information (S-VoI) decision making model for HTA under uncertainty to show that the static value of information approach leads to lower expected benefit and poses costs, both in terms of resources and forgone health gains, on the health care system.
Modeling Super‐Eddington Accretion Flow

Super‐Eddington (or supercritical) accretion flow seems to be realized in many astrophysical situations, such as ultra‐luminous X‐ray sources. We first discuss several noteworthy observable features of the supercritical accretion flow based on the framework of (1) one‐dimensional, slim disk model. We expect flatter temperature profile, if the accretion rate exceeds the critical rate, and we find such a signature in the X‐ray data of some ULXs. We then examine the data of (2) multi‐dimensional, global radiation‐hydrodynamic (RHD) simulations of disk accretion. Effects of relativistic beaming and gas outflow are particularly stressed there. Finally, we present our most recent results of (3) global, radiation‐magnetohydrodynamic (RMHD) simulations of accretion flow. This model could for the first time reproduce the three different regimes of accretion (supercritical, standard‐type, and radiatively inefficient accretion flow) with the same code by varying the density normalization.
