description: We explore some aspects of the relationship between biological evolution processes and the mathematical theory of records. For Eigen's quasispecies model with an uncorrelated fitness landscape, we show that the evolutionary trajectories traced out by a population initially localized at a randomly chosen point in sequence space can be described in close analogy to record dynamics, with two complications. First, the increasing number of genotypes that become available with increasing distance from the starting point implies that fitness records are more frequent than for the standard case of independent, identically distributed random variables. Second, fitness records can be bypassed, which strongly reduces the number of genotypes that take part in an evolutionary trajectory. For exponential and Gaussian fitness distributions, this number scales with sequence length $N$ as $\sqrt{N}$, and it is of order unity for distributions with a power law tail. This is in strong contrast to the number of records, which is of order $N$ for any fitness distribution.

description: Particle decay during inflation is studied by implementing a dynamical renormalization group resummation combined with a small Delta expansion. Delta measures the deviation from the scale invariant power spectrum and regulates the infrared. In slow roll inflation, Delta is a simple function of the slow roll parameters epsilon_V, eta_V.We find that quantum fluctuations can self-decay as a consequence of the inflationary expansion through processes which are forbidden in Minkowski space-time. We compute the self-decay of the inflaton quantum fluctuations during slow roll inflation.For wavelengths deep inside the Hubble radius the decay is enhanced by the emission of ultrasoft collinear quanta, i.e. bremsstrahlung radiation of superhorizon quanta which becomes the leading decay channel for physical wavelengths H<3.6 10^{-9}.

description: Das Ziel der vorliegenden Arbeit besteht in der Betrachtung der Standardformel und eines möglichen (partiellen) internen Modells bezüglich des versicherungstechnischen Risikos. Mit einem Modellbestand werden dabei die einzelnen von der EIOPA vordefinierten Stressszenarien mit Projektionen dargestellt und bewertet. Der Schwerpunkt liegt dabei auf den Methoden der Standardformel. Für den Musterbestand wird ein Bestand mit stationären Leistungen gewählt, welche in Österreich mehr als 3/4 der privaten Krankenversicherungen ausmachen. In dieser Arbeit wird lediglich das versicherungstechnische Risiko behandelt, ohne der Miteinbeziehung zusätzlicher vielleicht noch gewichtigerer Stressfaktoren, wie etwa dem Marktrisiko oder des operationellen Risikos. Des weiteren wird auch nicht auf das Katastrophenrisiko eingegangen.
description: The aim of this work is the consideration of the standard formula and a possible (partial) internal model regarding the actuarial risks. Shock scenarios predefined by the EiOPA as well as a model inventory are used for calculations and projections, whereby the main focus lies on the methods of the standard model. For the model inventory as an inpatient inventory is used which represents more than 3/4 of the patients with private health insurance in Austria. This work specifically addresses the underwriting risk without dealing with other important stress risks such as the market risk or the operational risk, furthermore the catastrophe risk is also not covered in this analysis.

description: We revisit the radial oscillator from the free oscillator realization point of view. By using a free oscillator, namely the creation/annihilation operators of the harmonic oscillator, we construct an operator that maps the eigenfunctions of the harmonic oscillator to those of the radial oscillator. As a polynomial part of this relation, we obtain an operator that maps the Hermite polynomials to the Laguerre polynomials.

description: hazai kézműves cukrásziparban az elmúlt évtizedekben számos változás ment végbe, az ágazat belső problémákkal küzd, továbbá a megváltozott fogyasztói szokásokra is próbál reagálni. A tanulmány célja a kézműves cukrászipari termékek fogyasztási és vásárlási szokásainak, illetve az azokat befolyásoló legfontosabb tényezőknek a vizsgálata Magyarországon. Primer kutatási módszerként a megkérdezés személyes és online formáját alkalmaztuk. A minta nagysága 538 fő. Az elemzés során leíró statisztikai módszereket és nem paraméteres eljárásokat használtunk. Az eredmények alapján kijelenthető, hogy a megkérdezettek többsége fogyaszt cukrászipari termékeket. A fogyasztók leggyakrabban cukrászdákban vásárolnak a kikapcsolódás, feltöltődés, illetve a magasabb minőség miatt. A fővárosban élők, felsőfokú végzettséggel rendelkezők és aktív szellemi dolgozók jobban preferálják a minőségi, de drágább kézműves termékeket. Az ár leginkább a 20 év alattiak, a falvakban élők és a 100 ezer forint alatti egy főre jutó havi nettó jövedelemmel rendelkezők számára fontos. ----------------------------------------------- Domestic confectionery has been subject to many changes in the recent decades; this sector suffers from internal problems and tries to reply to the changed consumer habits. The objective of this study is to analyse the Hungarian consumer and customer habits relating to confectionery products, and their factors of influence. As the primary research method we used personal interviews and online inquiry. The size of the sample was 538 respondents. Descriptive statistical techniques and non-parametric methods were used. Results show that the majority of the respondents consume confectionery products. The consumers mostly purchase products from confectioneries, because of relaxation and unique, prime pastries. People live in the capital, higher educated people and white collar workers prefer better the quality, but expensive craftsman products. Price is the most important for people under 20 years of age, people live in villages and people with net monthly income of under HUF 100 000.
Variation in ATM and genetic susceptibility to non-Hodgkin lymphoma
Creators: name: Sipahimalani, Payal
Publisher: name: University of British Columbia
Year: 2010

description: The ataxia telangiectasia mutated (ATM) gene is critical for the detection and repair of double stranded breaks. Mutations in this gene cause the autosomal recessive syndrome ataxia telangiectasia (AT), a feature of which is a high risk of cancer, particularly lymphoma. We have undertaken a population-based case/control study to assess the role of genetic variation in ATM on the risk of non-Hodgkin lymphoma (NHL) in the general population. The term NHL encompasses several subtypes, many of which have in common the occurrence of specific somatic translocations that contribute to lymphomagenesis. We hypothesize that variants that result in slightly decreased function of ATM could reduce DNA double-stranded break repair capacity, contributing to the occurrence of translocations and subsequent lymphomas. The study population consists of 798 NHL cases and 793 controls that are frequency matched by region, age, sex and ethnicity. Genetic variation in the promoter and all exons of ATM was determined by hi-directional sequencing of the germline (blood) DNA of 86 NHL patients, both T and B-cell. Sequencing revealed 79 variants, 18 of which correspond to amino acid differences. Six of these variants are predicted to be deleterious to protein function; these variants were all rare (0.5-1.1%). Seven of the 86 (8.1%) NHL patients were heterozygous at these loci. Eleven variants were present at a frequency of 5% or greater; these make up 10 haplotypes. Seven tagSNPs were predicted to specify these 10 haplotypes. Linkage disequilibrium across the ATM gene is high but not complete. Six tagSNPs (1 failed in assay design) and the 6 putatively deleterious variants were genotyped in the entire case/control set. Direct association tests based on the tagSNPs and haplotype-based indirect association tests were performed. The six rare variants were also assessed. The results of the association tests indicate that common variants of ATM do not significantly contribute to the overall risk of NHL in the general population. Our results, however, point to the possibility of a rare variant-rare disease model where some rare, functionally deleterious variants may contribute to an increased risk of development of rare subtypes of the disease.

description: This review covers age-dating methods applied to young stellar populations in starburst galaxies with ages of 10^8 yr and less. First, recent advances in stellar modeling, both for the interior and the atmospheres, are discussed and spectral lines and colors suitable for age-dating are identified. These age indicators are then applied to single stellar populations, the simplest building blocks of starbursts. More complex systems, such as luminous starburst galaxies, are a challenge for chronometric measurements. The dust reddening, metallicity, stellar initial mass function, and inhomogeneities of the interstellar medium introduce degeneracies which are often hard to resolve. Finally, some shortcomings in the stellar models are highlighted.

Drawing as problem-solving : young children’s mathematical reasoning through the act of drawing
Creators: name: Saundry, Carole
Publisher: name: University of British Columbia
Year: 2010

description: This project investigates how young children employ mathematical reasoning through the act of drawing while solving mathematical problems. Included is an examination of how grade 2 children responded when presented with two mathematical problems to solve, the kinds of pictures or representations they drew spontaneously - and the purpose for those drawing - what students were thinking while they drew, and how (or if) the act of drawing or the drawings themselves were helping students to reason through the problems. Considered together, video footage of students using drawing as a problem-solving strategy, children’s completed representational work and student interview data informed the creation of a framework for examining students’ drawing as problem-solving strategies and behaviours. Four categories of student behaviour emerged from this analysis, namely: the use of virtual manipulatives, the application of a system, the use of imagery and an examination of the sophistication of students’ representations. These categories form a framework that provides a lens for understanding children’s mathematical reasoning as expressed through and derived from the act of drawing. Questions regarding problem structure and complexity and their impact on student reasoning through pictures are also addressed. Implications of the study are elaborated, and involve a reconceptualizing of drawing in mathematical problem-solving to include a more performance-based approach, observing thinking in the act of thinking, reasoning while drawing. Recommendations for classroom practice are made regarding how teachers can support children in developing these active and metacognitive skills. Further research directions are suggested in the discussion of the results.

description: This study aims to investigate the dynamics of the effects of world crude oil prices and world rice prices on Indonesia’s inflation rate in the period between January 2004 and September 2015. Monthly time series data spanning from January 2004 to September 2015 are analyzed using difference equation model as the econometric tool. Test result shows that there existed a dynamic effect of world oil crude prices and world rice prices on inflation rate in Indonesia. The World crude oil prices positively affected the inflation rate in that each 1% increase (decrease) in the world crude oil prices caused the inflation rate to go up (drop) by 0.33%. The world rice prices also positively affected the inflation rate, where each 1% increase (decrease) in world rice prices was followed by a 0.52% rise (fall) of the inflation rate.

description: We build exactly solvable lattice Hamiltonians for fermionic symmetry-protected topological (SPT) phases in (3+1)D classified by group supercohomology. A central benefit of our construction is that it produces an explicit finite-depth quantum circuit (FDQC) that prepares the ground state from an unentangled symmetric state. The FDQC allows us to clearly demonstrate the characteristic properties of supercohomology phases - namely, symmetry fractionalization on fermion parity flux loops - predicted by continuum formulations. By composing the corresponding FDQCs, we also recover the stacking relations of supercohomology phases. Furthermore, we derive topologically ordered gapped boundaries for the supercohomology models by extending the protecting symmetries, analogous to the construction of topologically ordered boundaries for bosonic SPT phases. Our approach relies heavily on dualities that relate certain bosonic 2-group SPT phases with supercohomology SPT phases. We develop physical motivation for the dualities in terms of explicit lattice prescriptions for gauging a 1-form symmetry and for condensing emergent fermions. We also comment on generalizations to supercohomology phases in higher dimensions and to fermionic SPT phases outside of the supercohomology framework.

description: We extend vector formalism by including it in the algebra of split octonions, which we treat as the universal algebra to describe physical signals. The new geometrical interpretation of the products of octonionic basis units is presented. Eight real parameters of octonions are interpreted as the space-time coordinates, momentum and energy. In our approach the two fundamental constants, $c$ and $\hbar$, have the geometrical meaning and appear from the condition of positive definiteness of the octonion norm. We connect the property of non-associativity with the time irreversibility and fundamental probabilities in physics.

description: A complete set of wave solutions is given for the weak field in a Kaluza-Klein theory with degenerate metric. In the five-dimensional version of this theory electromagnetism is described by two vector fields, and there is a reflection symmetry between them which unifies them with gravitation; wave behaviour in the extra dimension has been interpreted as dark matter. Here three independent dark matter solutions are found, and for two of them it is shown how they must be combined into a single solution in order to obey the reflection symmetry. The unification is also expanded to six dimensions to prepare the way to include further forces.

In the continuum limit we find r_0^4 chi = 0.059(3), which corresponds to chi=(191 \pm 5 MeV)^4 if F_K is used to set the scale. Our result supports the Witten--Veneziano explanation for the large mass of the eta'.

Theoretical studies of the kinetics of mechanical unfolding of cross-linked polymer chains and their implications for single molecule pulling experiments

description: We have used kinetic Monte Carlo simulations to study the kinetics of unfolding of cross-linked polymer chains under mechanical loading. As the ends of a chain are pulled apart, the force transmitted by each crosslink increases until it ruptures. The stochastic crosslink rupture process is assumed to be governed by first order kinetics with a rate that depends exponentially on the transmitted force. We have performed random searches to identify optimal crosslink configurations whose unfolding requires a large applied force (measure of strength) and/or large dissipated energy (measure of toughness). We found that such optimal chains always involve cross-links arranged to form parallel strands. The location of those optimal strands generally depends on the loading rate. Optimal chains with a small number of cross-links were found to be almost as strong and tough as optimal chains with a large number of cross-links. Furthermore, optimality of chains with a small number of cross-links can be easily destroyed by adding cross-links at random. The present findings are relevant for the interpretation of single molecule force probe spectroscopy studies of the mechanical unfolding of load-bearing proteins, whose native topology often involves parallel strand arrangements similar to the optimal configurations identified in the study.

description: Bose-Einstein condensates can be used to produce work by tuning the strength of the interparticle interactions with the help of Feshbach resonances. In inhomogeneous potentials, these interaction ramps change the volume of the trapped gas allowing one to create a thermodynamic cycle known as the Feshbach engine. However, in order to obtain a large power output, the engine strokes must be performed on a short timescale, which is in contrast with the fact that the efficiency of the engine is reduced by irreversible work if the strokes are done in a non-adiabatic fashion. Here we investigate how such an engine can be run in the Thomas-Fermi regime and present a shortcut to adiabaticity that minimizes the irreversible work and allows for efficient engine operation.

description: An equation of state for a multicomponent mixture of non-additive hard spheres in $d$ dimensions is proposed. It yields a rather simple density dependence and constitutes a natural extension of the equation of state for additive hard spheres proposed by us [A. Santos, S. B. Yuste, and M. López de Haro, Mol. Phys. 96, 1 (1999)]. The proposal relies on the known exact second and third virial coefficients and requires as input the compressibility factor of the one-component system. A comparison is carried out both to another recent theoretical proposal based on a similar philosophy and to the available exact results and simulation data in $d=1$, 2, and 3. Good general agreement with the reported values of the virial coefficients and of the compressibility factor of binary mixtures is observed, especially for high asymmetries and/or positive nonadditivities.

description: Objective: Diet and Physical activity modifications are prescribed to women with polycystic ovary syndrome (PCOS). This study aimed to evaluate the correlation of physical activity and nutrition-related Knowledge, attitudes, and practices with obesity indices in young women with PCOS.Methods: This cross sectional study was conducted on 309 young college women(age:21.5kg/m2) with PCOS who participated in the study voluntarily. They filled out a modified Wellness Knowledge, Attitude, and Behavior Instrument (WKABI), performed the step test to measure their maximum rate of oxygen consumption (VO2max), and their weight, height, and waist circumstance were measured to estimate their body mass index (BMI) and waist to height (WHtR).Results: There was no significant correlation between physical activity knowledge with physical activity attitude and practices. There was a significant correlation between physical activity attitude with practices, between nutrition knowledge and attitude, and between nutrition attitude and practices, while there was no significant correlation between nutrition knowledge and practices. There was a negative significant correlation between WHtR with VO2max and physical activity, and between BMI and VO2max.Conclusions: Nutrition or physical activity knowledge was not correlated with practice, and improving attitude was correlated with improving practice. VO2max and physical activity by priority were the important predictors of obesity indices

description: High-resolution gamma-ray spectrometry was exploited to determine naturally occurring thorium (Th), uranium (U) and potassium (K) elemental concentrations in the whole area covered by the Troodos Ophiolite Complex of Cyprus. For that purpose, a total of 59 samples from surface soils and 10 from the main rock formations of the region of interest were analysed. Elemental concentrations were determined for Th (range from 2.5x10^-3 ppm to 2.0 ppm), U (from 8.1x10^-4 ppm to 0.6 ppm), and K (from 1.3x10^-4 % to 1.0 %). The average values (A.M +- S.D.) derived are (0.24 +- 0.34) ppm, (0.10 +- 0.10) ppm and (0.21 +- 0.24) %, for Th, U, and K, respectively, in the soils, and (0.52 +- 0.17) ppm, (0.17 +- 0.11) ppm and (0.49 +- 0.87) % in the rocks. From these values, a radioactivity (radioelement) loss of nearly 50% is estimated in the underlying surface soils due to bleaching and eluviation during weathering of the rocks. The measured Th/U ratio exhibits values between 2 and 4, whereas the K/Th ratio is highly variable ranging between 1.5x10^3 and 3.0x10^4.

Moreover this universal machine acts as a catalyst in that it is unchanged after either procedure, effectively resetting itself for its next operation. It also possesses an inherent {\em immunity} to decoherence. Most importantly in terms of practical multi-party quantum communication, the machine's robustness in the presence of decoherence actually {\em increases} as the number of qubits $M$ increases.

description: Minimal supergravity mediation of supersymmetry breaking has attracted much attention due to its simplicity, which leads to its predictive power. We consider how Nature possibly realizes minimal supergravity through inflationary selection of the theory. Minimality is impressively consistent with the present observational bounds and it might be tested with the aid of low-energy soft parameters obtained in future experiments.

description: In the literature and sectoral policy strategies, a generation change among farm managers is often linked with the expectations of positive developments in agriculture and rural areas. The farm succession is usually perceived as favourable for economic situation of farming families. As a consequence of this process diff erent methods of management are often implemented. The new farmer’s experiences, ideas and skills that could contribute to the development of production and improvement of its profi tability are also brought. The aim of this paper is to describe the changes that have occurred in the farms after succession. In total, among this group an increased number of actions aimed at the development of the agricultural businesses were not observed. However, analyses showed that among successors diff erent attitudes towards acquired production assets were observed. The empirical material used in the study were the results of the IAFE-NRI panel surveys conducted on a sample of more than 2,5 thousand of the same farms in 2000, 2005 and 2011.
Seismic structural health monitoring of bridges

Publisher: name: University of British Columbia

description: Seismic Structural Health Monitoring (SSHM) is defined here as the process to determine the status of serviceability of a structure immediately after an earthquake. This can be done remotely via the Internet or any suitable communication link. In this study, a procedure was introduced for SSHM of bridges with limited strong motion instrumentation. This procedure is developed and presented in a flowchart format, which can be easily implemented as a user-friendly software. The SSHM Procedure is able to analyze the recorded motions by the sensors installed on a bridge after an earthquake and determine the serviceability status of the structure. The level of serviceability can be easily determined by the procedure as Safe, Limited or Out of Service. It can also determine the location and severity of the damages sustained, if any. This procedure is a combination of the results of two main components: those from the use of a structural health monitoring (SHM) technique and those from a series of nonlinear structural analyses. This combination can minimize the errors and misinterpretation of results, which may arise from the independent implementation of each component. The Damage Index Method (DIM) is the SHM method used in this study, and has been critically reviewed. This is the first time the DIM has been used on a real bridge with very limited number of sensors. An actual bridge (the Painter Street Overpass Bridge located in California), which has been instrumented and has experienced more than ten earthquakes of different intensities was selected as a case study. The proposed SSHM was implemented to assess the status of the bridge for selected earthquakes. Complementary strong motion records were generated to induce artificial levels of damage to a well calibrated finite element model of the bridge, and the results from these analyses were used to further assess the effectiveness of the proposed procedure. The proposed SSHM procedure is shown to be accurate, rational and relatively easy to implement in engineering practice.

subject: Poland

description: The main purpose of the article is to present legal basis and guarantees of the farmers’ trade unions’ functioning in Poland. The presented research was based on a thorough examination of national legal acts, which constitute both legal background and foundation of farmer’s unions’ activities and internal structure. The author tries to introduce both the individual legal and system guarantees which are dedicated to farmers’ organization and which exact acts shall be considered as the direct legal basis of the guarantees. Having regard to the fact that even the Polish Constitution introduces transparent and direct legal frameworks for functioning of farmers’ trade unions, the author intends to prove that individual farmers’ unions’ operations should be considered as a fundamental and basic feature of the national agricultural system. The presented work should be also considered as thorough examination of legal provisions presented in the Act on individual farmers’ trade unions of 7th April 1989 (Ustawa…, 2015b), which is direct legal basis for functioning guarantees of the agricultural unions. The author shows how the Act is governing such fundamental issues as creation, registration, liquidation or legal operational guarantees of each individual farmers’ trade unions operating under the Act.
title: Stepmothering and Identity: A Synthetic Narrative-Discursive Analysis
Creators: name: Roper, Sandra Lyn
Publisher: name: The Open University
Year: 2017

description: In Britain in the twenty-first century stepfamilies are numerically common but difficult to define since they may cross household boundaries. This has meant that stepmother families, who are often non-residential, are rarely included in research and there is a very limited literature which considers the perspectives of stepmothers themselves. However, there have been research findings suggesting greater stress for stepmothers than stepfathers. In a neoliberal climate there are increasing demands on parents, including fathers who do not live with the biological mother of their children, and this may contribute to particular stresses for stepmother families. This research used a synthetic narrative-discursive methodological approach, underpinned by feminist theory, to explore the identity work undertaken by stepmothers. In order to maximise the diversity of participants, data were drawn from a web forum for stepmothers and interviews with stepmothers of adult stepchildren. The analysis considers the discursive resources drawn upon as stepmothers negotiate potentially troubled identities. The empirical work is presented in three chapters: the first considers stepmothers talk about their (male) partners in which the men were often constructed as hapless, helpless or hopeless. The second looks at talk of home both as a physical and a relational space. In this stepmothers frequently demonstrated their own feelings of both invasion and exclusion, often not feeling ‘at home’. The third explores stepmothers’ talk in which the biological mothers of their stepchildren are often constructed as mad, bad and sometimes dangerous. The concluding chapter summarises the particular troubles with which stepmothers must contend highlighting the discursive resources that are drawn on and the constraints that these impose. Theoretical, methodological and empirical contributions are discussed including suggestions for policy. There are also discussions of future possibilities for extensions to this research exploring the experiences of the growing number of families with adult stepchildren.
Effects of Rescattering in (e,e'p) Reactions within a Semiclassical Model

description: The contribution of rescattering to final state interactions in (e,e'p) cross sections is studied for medium and high missing energies using a semiclassical model. This approach considers two-step processes that lead to the emission of both nucleons. The effects of nuclear transparency are accounted for in a Glauber inspired approach and the dispersion effects of the medium at low energies are included. It is found that rescattering is strongly reduced in parallel kinematics. At high missing energy and momenta, the distortion of the short-range correlated tail of the spectral function is dominated by a rearrangement of that strength itself. In perpendicular kinematics, a further enhancement of the experimental yield is due to strength that is originally in the mean field region. This contribution becomes negligible at large missing momenta.

description: Stimulated Raman adiabatic passage (STIRAP) is a standard technique to combat experimental imperfections and can be used to realize robust quantum state control, which has many applications in physics, chemistry, and beyond. However, STIRAP is susceptible to decoherence since it requires long evolution time. To overcome this problem, stimulated Raman user-defined passage (STIRUP) is proposed, which allows users to design the passages unlike the STIRAP but fast and robust against both decoherence and experimental imperfections. Here, we further develop a more general STIRUP method. Comparing with shortcut to adiabaticity and its' variants, the generalized STIRUP is more simpler and compatible with more complex energy-level structure and manybody systems. Furthermore, the generalized STIRUP has many important applications such as geometric phase measurement, coherent population transfer, and quantum state preparation. Specifically, as examples, we show how to realize the high-fidelity quantum state transfer and entangled state generation in a robust way via STIRUP with the state-of-the-art experimental superconducting circuits.

subject: electric car support

description: The fossil fuel dependency and the desire to reduce pollution levels mean that the electric vehicle has set off as an attractive mobility alternative in recent years. The purpose of this study is to review the main barriers that electric vehicle must curb if it is to become an acceptable mode of transport and to review the main public policies that governments might put in action to help in dealing these obstacles. Public policies have been projected for four basic issues of the electric vehicle: the infrastructure; triggering demand for these vehicles; research and development programs; and the introduction of electric vehicles in sustainable mobility agendas. The effect of different implemented measures is however sacrce and monitored through comparable aluations on the environment, economics and society.
