description: This paper looks to apply the mathematical framework of the Theory of Functional Connections to the solution of boundary-value problems arising from hybrid systems. The Theory of Functional Connections is a technique to derive constrained expressions which are analytical expressions with embedded constraints. These expressions are particularly suitable to transform a large class of constrained optimization problems into unconstrained problems. The initial and most useful application of this technique is in the solution of differential equations where the problem can be posed as an unconstrained optimization problem and solved with simple numerical techniques (i.e. least-squares). A hybrid system is simply a sequence of different differential equations. The approach developed in this work derives an analytical constrained expression for the entire range of a hybrid system, enforcing both the boundary conditions as well as the continuity conditions across the sequence of differential equations. This reduces the searched solution space of the hybrid system to only admissible solutions. The transformation allows for a least-squares solution of the sequence for linear differential equations and a iterative least-squares solution for nonlinear differential equations. Lastly, the general formulation for "n" segments is developed and validation is provided through numerical tests for three differential equation sequences: linear/linear, linear/nonlinear, and nonlinear/nonlinear. The accuracy level obtained are all at machine-error, which is consistent with the accuracy experienced in past studies on the application of the Theory of Functional Connections to solve single ordinary differential equations.

description: The Callovo-Oxfordian (COx) claystone is considered as a candidate host rock for a deep geological radioactive waste repository in France. Due to the exothermic waste packages, the rock is expected to be submitted to temperatures up to 90 °C. The temperature rise induces deformations of the host rock, together with an increase in pore pressures, involving complex thermo-hydro-mechanical (THM) couplings. This study aims to better characterize the THM response of the COx claystone to temperature changes in the laboratory. To this end, claystone specimens were tested in a temperature controlled, high pressure isotropic compression cell, under stress conditions close to the in-situ ones. Thermal loads were applied on the specimens along different heating and cooling paths. A temperature corrected strain gage system provided precise measurements of the anisotropic strain response of the specimens. Drained and undrained thermal expansion coefficients in both transversely isotropic directions were determined. The measurement of pore pressure changes in undrained condition yielded the thermal pressurization coefficient. All parameters were analysed for their compatibility within the thermo-poro-elastic framework, and their stress and temperature dependency was identified.

description: This research examines how two contextual factors – verbal solicitation of advice and latent receptiveness to advice – affect advice outcomes, and whether these effects are mediated through perceived face threats. A survey of recent advice-receiving interactions (Study 1) and a hypothetical scenario study (Study 2) were conducted to examine recipient outcomes. When recipients wanted some advice, advice outcomes were more desirable. A significant interaction between the two factors suggests that individuals who received unsolicited advice evaluated the received advice as lower in utility and were less likely to implement it than those who received solicited advice – but only when the receptiveness to advice was absent. Negative face threats played a mediating role. Implications for advice response theory are discussed.

Detection of heavy charged Higgs bosons in $e^+e^-\to t\bar b H^-$ production at future Linear Colliders

description: Heavy charged Higgs bosons ($H^\pm$) of a Type II 2-Higgs Doublet Model (2HDM) can be detected at future electron-positron Linear Colliders (LCs) even when their mass is larger than half the collider energy. The single Higgs mode $e^+e^-\to t\bar b H^- + ~{\rm{c.c.}} \to 4b +{\rm{j}}{\rm{j}} + \ell + p_T^{\rm{miss}}$ (where j represents a jet and with $\ell=e,μ$) contributes to extend the discovery reach of $H^\pm$ states into the mass region $M_{H^\pm}\gsim \sqrt s/2$, where the well studied pair production channel $e^+e^-\to H^-H^+$ is no longer available. With a technique that allows one to reconstruct the neutrino four-momentum in the decay $t\to b W^+\to b \ell^+ν$, one can suppress the initially overwhelming main irreducible background due to $e^+e^-\to t\bar t b\bar b$ (via a gluon splitting into $b\bar b$ pairs) to a negligible level. However, for currently foreseen luminosities, one can establish a statistically significant $H^\pm$ signal only over a rather limited mass region, of 20 GeV or so, beyond $M_{H^\pm}\approx \sqrt s/2$, for very large or very small values of $\tanβ$ and provided high $b$-tagging efficiency can be achieved.

description: This article proposes an alternative constraint handling technique for the four-bar linkage path generation problem. The constraint handling technique that is traditionally applied uses an exterior penalty function, and has been found to be inefficient, particularly when dealing with constraints on the input angles. The new technique deals with both input crank rotation and Grashof's criterion. Four classical path generation problems are used to test the performance of the proposed technique. A new adaptive teaching–learning-based optimization (TLBO) scheme is used to solve several optimization problems. This technique is referred to here as teaching–learning-based optimization with a diversity archive (ATLBO-DA), and was specifically developed for this design problem. The results show that this new design concept gives better results than those of previous work, and that ATLBO-DA is superior to the original version and other metaheuristic algorithms.

description: Present-day industrialization processes influencing environmentally questionable methods of urban production, could be considered agents of ecological debasement at scales beyond the constituent spatial context of its built products. This project considers that although ongoing urban infrastructural expansion is required to rapidly supply for the increased demand for access to modern urban living conditions, the streamlined global processes deployed for its construction and maintenance, hold the potential to contribute to the disruption of coastal ecosystems that serve to maintain anthropocentric urban activity. This project develops through the investigation of industrial urbanization's impacts on coastal urban ecologies. It analyzes the northeastern territory of the Yucatan Peninsula in the southeast of Mexico, a territory that has faced continual environmental challenges that have contributed to the ecosystem's decreased capacity to sustain the cultural activity that urban development created. Through a chronological sequence, this thesis explores ecologically-restorative technology's integration into socially equitable and environmentally just frameworks for urban production. The design project intends to communicate a methodology to catalyze the future ecologically resilient urban archetypes of the Yucatan Peninsula, Mexico, and potentially, the world.

description: The complexity of public administration, as one of the most pressing problems which citizens of the Republic of Serbia are facing, led to inefficiency and non-responsiveness, as well as the dissatisfaction of citizens who do not have alternative options to meet their needs. Under the impact of financial crisis, governments are forced to reduce their costs, volume of administration, to build online connections and relationships with citizens and businesses. Realizing that they, like the companies, must transform themselves to meet requirements and obtain satisfaction of citizens, governments have found very powerfull tool for overcoming the problems – information and communication technology (ICT) and electronic government. The aim of this paper is to show that the evolution from electronic government toward lean government should be the backbone of any modern information society and a key competitive advantage that will bring greater efficiency of society as a whole.

description: Resolved debris disk features (e.g., warps, offsets, edges and gaps, azimuthal asymmetries, radially thickened rings, scale heights) contain valuable information about the underlying planetary systems, such as the posited planet's mass, semi-major axis, and other orbital parameters. Most existing models assume a single planet is sculpting the disk feature, but recent observations of mature planetary systems (e.g., by radial velocity surveys or \textit{Kepler}) have revealed that many planets reside in multi-planet systems. Here we investigate if/how planet properties inferred from single-planet models are compromised when multiple planets reside in the system. For each disk feature, we build a two-planet model that includes a planet b with fixed parameters and a planet c with a full range of possible parameters. We investigate these two-planet systems and summarize the configurations for which assuming a single planet (i.e., planet b) leads to significantly flawed inferences of that planet's properties. We find that although disk features are usually primarily dominated by a single planet, when using single-planet models we are at risk of misinterpreting planet properties by orders of magnitude in extreme cases. Specifically, we are at high risk of misinterpreting planet properties from disk warps; at moderate risk from disk edges and gaps, radially thickened rings, and scale height features; and at low risk from host star-disk center offsets and azimuthal asymmetries. We summarize situations where we can infer the need to use a multi-planet model instead of a single-planet one from disk morphology dissimilarities.

Turbulent changes, tendencies and trends in the part of tourism demand and on the side of the tourism supply, as well, greatly affect business behavior and response to the tourist destination and thus require strategic marketing. However, the strategic marketing process is very complex and for its successful implementation is necessary to ensure the unity of the participants, because if it’s not provided marketing strategies won’t be properly implemented which will result in reduction of the competitiveness of tourist, profits, etc.

description: In the context of integrable partial difference equations on quad-graphs, we introduce the notion of open boundary reductions as a new means to construct discrete integrable mappings and their invariants. This represents an alternative to the well-known periodic reductions. The construction deals with well-posed initial value problems for quad equations on quad-graphs restricted to a strip. It relies on the so-called double-row monodromy matrix and gives rise to integrable mappings. To obtain the double-row monodromy matrix, we use the notion of boundary matrix and discrete boundary zero curvature condition, themselves related to the boundary consistency condition, which complements the well-known $3$D consistency condition for integrable quad equations and gives an integrability criterion for boundary equations. This relation is made precise in this paper. Our focus is on quad equations from the Adler-Bobenko-Suris (ABS) classification and their discrete integrable boundary equations. Taking as our prime example a regular $\mathbb{Z}^2$-lattice with two parallel boundaries, we provide an explicit construction of the maps obtained by open boundary reductions, the boundary matrices, as well as the invariants extracted from the double-row monodromy matrix. Examples of integrable maps are considered for the H1 and Q1($δ=0$) equations and an interesting example of a non-QRT map of the plane is presented. Examples of well-posed quad-graph systems on a strip beyond the $\mathbb{Z}^2$-lattice are also given.

description: Background: While it is apparent that much has been learned about “mental health literacy” (MHL) relating to certain mental health problems, such as depression, in recent years, what has been learned about MHL relating to eating disorders (ED-MHL) is unclear. Aims: A scoping review was conducted to inform the current state of knowledge in this field. Methods: A systematic search of relevant literature published between 1997 and 2017 was followed by a narrative synthesis of the findings. Results: The number of eligible studies increased from 32 in 1997–2001 to 98 in 2012–2017 (total = 264). Most studies originated from North America or Europe, recruited individuals with EDs receiving treatment or college students and included both female and male or only female participants. The majority of studies examined MHL relating to anorexia nervosa or bulimia nervosa and examined attitudes which facilitate recognition and appropriate help-seeking and knowledge and beliefs about professional help available. Conclusion: Interest in ED-MHL is increasing and there is now a considerable body of research addressing some aspects of ED-MHL in a range of study populations. Notable gaps in the literature exist, including a paucity of information about ED-MHL relating to EDs other than anorexia nervosa and bulimia nervosa, ED behaviour in males and the use of self-help interventions. We hope the findings will provide an incentive to further research in these and other aspects of ED-MHL.

description: Beginning of the twentieth century brought great challenges, great sacrifices and great victories Serbian people. Political and economic conflict with the Austro - Hungarian empire , the wars with Turkey and Bulgaria, and finally the First World War brought a great victory and at the same time new challenges. The creation of the Kingdom of Serbs, Croats and Slovenes was supposed to bring peace deadbeat Serbian people. That, however, did not think the new citizens, notably the Croats, but some minorities (Albanians, Hungarians, etc.). Though defeated in war, in peace they quickly turned against the Serbs, although their rights have been equal to or greater than those enjoyed Serbian people. In addition, one new group, the Communist Party of Yugoslavia, glorified the anti-Serbian and conducted many terrorist actions. Therefore, the period from the 1919th until in 1929. Age was infused with political conflicts and crises and parliamentary government. Beginning dictatorship was an attempt to calm this situation with a significant share of the King. There have also been forming unit’s administrations - duchies, which were supposed to mitigate inter-regional differences. While people in most, had a negative attitude towards these changes, after the death of King Alexander policies, integral Yugoslav abandoned.
The star formation timescale of elliptical galaxies -- Fitting [Mg/Fe] and total metallicity simultaneously

description: The alpha element to iron peak element ratio, for example [Mg/Fe], is a commonly applied indicator of the galaxy star formation timescale (SFT) since the two groups of elements are mainly produced by different types of supernovae that explode over different timescales. However, it is insufficient to consider only [Mg/Fe] when estimating the SFT. The [Mg/Fe] yield of a stellar population depends on its metallicity. Therefore, it is possible for galaxies with different SFTs and at the same time different total metallicity to have the same [Mg/Fe]. This effect has not been properly taken into consideration in previous studies. In this study, we assume the galaxy-wide stellar initial mass function (gwIMF) to be canonical and invariant. We demonstrate that our computation code reproduces the SFT estimations of previous studies where only the [Mg/Fe] observational constraint is applied. We then demonstrate that once both metallicity and [Mg/Fe] observations are considered, a more severe "downsizing relation" is required. This means that either low-mass ellipticals have longer SFTs (> 4 Gyr for galaxies with mass below $10^{10}$ M$_\odot$) or massive ellipticals have shorter SFTs ($\approx 200$ Myr for galaxies more massive than $10^{11}$ M$_\odot$) than previously thought. This modification increases the difficulty in reconciling such SFTs with other observational constraints. We show that applying different stellar yield modifications does not relieve this formation timescale problem. The quite unrealistically short SFT required by [Mg/Fe] and total metallicity would be prolonged if a variable stellar gwIMF were assumed. Since a systematically varying gwIMF has been suggested by various observations this could present a natural solution to this problem.

Year: 2012

description: The DMVitals is a key component of the UVa Library's Scientific Data Consulting (UVa SciDaC) Group's research data interviews. The DMVitals is a tool to assess data management practices based on a series of best practices statements. With the DMVitals a data management consultant associates a list of data management practices to portions of the research data interview and rank reserachers' current practices base to their level of data "sustainability". The DMVitals tool generates customized and actionable recommendations to help researchers improve their data management practices. The tool also creates objective, repeatable recommendations that can be generated rapidly. This paper will detail the development of the DMVitals tool and describe how UVa SciDaC integrates it into their existing data interview and data management plan process to expedite the data management recommendation report process and to provide actionable feedback which researchers can use almost immediately to improve the sustainability of their data. The paper will also illustrate how the DMVitals can easily be integrated in other data management assessment tools such as the Digital Curatin Center's (DCC) CARDIO.

description: A classical single machine minmax common due-date assignment (CON) problem is studied. The problem is extended (independently) to the following settings: (1) general position-dependent job processing times are assumed, and an efficient O(n4) solution procedure is introduced; (2) the option of job rejection is allowed, and this case is shown to be solved in O(n5); (3) a deterioration effect is considered, and an O(n2) solution algorithm is proposed; (4) parallel uniform machines are considered; and (5) the machine setting is that of a permutation flowshop. The last two settings are known to be NP hard, and efficient heuristic procedures are introduced and shown numerically to produce very small optimality gaps.

description: Persistent organic pollutants (POPs) are organic compounds of anthropogenic origin that resist atmospheric and microbial degradation and thus persist in the environment and in food chains for exceptionally long periods of time. Veterinarians and wildlife researchers need simple methodologies for monitoring and measuring such compounds including two large and diverse categories, organochlorine pesticides (OCs) and polychlorinated biphenyls (PCBs), compounds that have been largely banned from production and use except for specific exceptions. We present development of methodologies for detection and quantitation of 22 OCs and 10 PCB congeners by tandem quadrupole gas chromatography-mass spectrometric analysis of Dried Blood Spots (DBS). Development was enabled by (1) optimization of suspension and extraction methodologies for DBS; (2) strategic streamlining and condensation of Multiple Reaction Monitoring (MRM) settings on GC/MS/MS; and (3) improvement of GC settings to accommodate all 32 compounds in a single chromatographic run per sample. The method was validated for parameters of linearity, limits of detection and quantitation, recovery and precision, and results from blood were shown to correlate well with those from DBS despite both being only 50 uL in volume. The method was applied successfully to blood samples from nine avian specimens submitted to the MSU Veterinary Diagnostic Lab, and all were shown to bear the burden of varying levels of OCs and/or PCB compounds.

description: The present article discusses a special variant of the multiphase transportation problem dealing with the transportation of a commodity from various origins to terminals when the set of origin–terminal links is divided into three disjoint partitions, namely Phase-1 links, Phase-2 links and Phase-3 links. Transportation of the commodity via Phase-2 links starts only after the completion of transportation in Phase-1, and similarly transportation in Phase-3 commences only after transportation in Phase-2 has been completed. The aim is to find a solution that minimizes the total time of transportation of the commodity subject to the constraints pertaining to origin availabilities and terminal requirements. The overall availability of the commodity at various origins is equal to the total demand at various terminals. An iterative polynomially bounded algorithm is proposed for obtaining an optimal feasible solution of the three-phase problem. Theoretical justification and numerical illustrations are provided to support the algorithm.

description: The paper illustrates how the education can contribute to the active citizenship in a theoretical way. It is possible to believe that people need teaching and learning to be active in the society. Former researches proved that those societies are more effective and more sustainable where the citizens participate in an active way in shaping their environment. But how can people learn those competences which are necessary to be active? Mainly the knowledge comes from the family, but the question arises: what can the education system add to these processes? Does the education have a role in active citizenship? This paper attempts to provide answers to these questions based on literature and international practices and opinions. The paper investigates the topic by using secondary information from researchers, practitioners and by showing some good examples in the field of active citizenship education. My paper demonstrates guidance for both researchers and for whom who would like to know more about the citizenship education. -------------------------------------------------- A tanulmány azt vizsgálja, hogy az oktatás hogyan tud hozzájárulni az aktív állampolgárságra neveléshez. Ahhoz, hogy az emberek aktívak legyenek a társadalomban, szükség van ennek tanulására. Korábbi kutatások már bizonyították, hogy egy olyan társadalom, ahol az állampolgároknak lehetőségük van beleszólni a körülöttük zajló folyamatokba sokkal hatékonyabban működik és hosszútávon fenntarthatóbb is. Kérdés, hogy az emberek hogyan és honnan tudják megtanulni azokat a kompetenciákat, amelyek ahhoz szükségesek, hogy aktívak tudjanak lenni? A tudás egyrészt jön a családból, másrészt szükség van az oktatásra is. A tanulmány arra keresi a választ, hogy az oktatásnak milyen szerepe van ebben a folyamatban. A tanulmány szekunder adatok felhasználásával elméleti síkon vizsgálja a témát, mely mind annak kutatói, mind gyakorló szakemberei számára hasznos iránymutatásokkal szolgálhat.

description: The X-ray emission of gamma-ray bursts (GRBs) is often characterized by an initial steep decay, followed by a nearly constant emission phase (so called "plateau") which can extend up to thousands of seconds. While the steep decay is usually interpreted as the tail of the prompt gamma-ray flash, the long-lasting plateau is commonly associated to the emission from the external shock sustained by energy injection from a long lasting central engine. A recent study proposed an alternative interpretation, ascribing both the steep decay and the plateau to high-latitude emission (HLE) from a "structured jet" whose energy and bulk Lorentz factor depend on the angular distance from the jet symmetry axis. In this work we expand over this idea and explore more realistic conditions: (a) the finite duration of the prompt emission, (b) the angular dependence of the optical depth and (c) the lightcurve dependence on the observer viewing angle. We find that, when viewed highly off-axis, the structured jet HLE lightcurve is smoothly decaying with no clear distinction between the steep and flat phase, as opposed to the on-axis case. For a realistic choice of physical parameters, the effects of a latitude-dependent Thomson opacity and finite duration of the emission have a marginal effect on the overall lightcurve evolution. We discuss the possible HLE of GW170817, showing that the emission would have faded away long before the first Swift-XRT observations. Finally, we discuss the prospects for the detection of HLE from off-axis GRBs by present and future wide-field X-ray telescopes and X-ray surveys, such as eROSITA and the mission concept THESEUS.

description: Sea-level rise is a significant threat to salt marshes. However, these habitats can respond by increasing their relative elevation, or by migrating into adjacent areas. Here we provide the first report on surface elevation change for salt marsh at the Knysna Estuary, South Africa, and predict the responses of these habitats to sea-level rise using the Sea-Level Affecting Marshes Model (SLAMM). Recent (2018) surface elevation measurements at lower intertidal salt marsh sites were compared with those from 2009–2011. The long-term (1960–2017) relative sea-level rise (RSLR) was estimated as 2.19 mm y−1 and only two of the seven sites assessed are keeping pace with this RSLR. The SLAMM, which was applied to a focus area near Thesen’s Island, predicted up to 40% loss of upper intertidal salt marsh by 2100, because development in the adjacent area prevents habitat migration. Currently, salt marsh habitats cover a total of 667 ha, and artificial structures are present along 20.7 km of the perimeter. Protecting areas for salt marsh migration should be a conservation priority, because this estuary supports the third largest area of intertidal salt marsh in the country. Monitoring the responses of coastal wetlands should be prioritised so that natural capital contributes towards future resilience.

description: Classifications JEL: Q10, Q13, Q18 The European Union (EU) has, since a long time, an important role in the international livestock industry chains, both in terms of production and trade. In spite of a strong restructuring movement, mainly due to factor productivity gains, European livestock brings together farms that are still very heterogeneous in terms of productive combinations, size, social structuring, intensification and economic performance. To document this, data from the Farm Accountancy Data Network (FADN) is used to analyze the diversity of structural and economic situations of farms specializing in the production of milk, beef and pigs/poultry, for the ten most productive EU Member States in animal production. This step is necessary for identifying the main levers for improving the economic performance of European animal productions. Two types of levers are distinguished. The first concerns the « cost competitiveness ». It refers successively to the substitution of production factors, economies of scale, the geographical concentration of production, the structuring of production chains and the impact of agricultural policies. The second concerns the « non-cost competitiveness ». It covers the sanitary quality of animal productions, the differentiation of products and production processes, and the required conditions for farmers to capture some of the generated value-added.

description: Data Observation Network for Earth (DataONE; https://www.dataone.org/) is supported by the National Science Foundation and will ensure the preservation of and access to multi-scale, multi-discipline, and multi-national science data about Earth. DataONE will make biological data available from the genome to the ecosystem; make environmental data available from atmospheric, ecological, hydrological, and oceanographic sources; and engage scientists, land-managers, policy makers, students, educators, and the public through logical access and intuitive visualizations. The DataONE Usability and Assessment Working Group is tasked with conducting a variety of assessments on aspects of the DataONE project. This presentation will discuss the results of a survey sent to data managers to assess current data management and data sharing needs, practices, and attitudes. IASSIST members were invited to participate in the survey via the listserv. Questions asked included how much data is deposited on public, internal, or personal websites, access/use conditions, the reasons data managers do not make their data available to others electronically, policies and processes for data deposition and storage, use of metadata to describe data and the metadata standards and tools used, training on best practices and adequate funding for data management, and data management plans, among other things.

description: We study zeta functions enumerating subalgebras or ideals of Lie algebras over finite field of prime order $\mathbb{F}_p$. We first develop a general blueprint method for computing zeta functions of $\mathbb{F}_p$-Lie algebras, and demonstrate its practical applications in detail to obtain explicit formulas for various interesting new examples that are not covered in any known literature yet. For nilpotent cases this also provides zeta functions counting subgroups and normal subgroups of finite $p$-groups of exponent $p$ for almost all primes via the Lazard correspondence. We investigate their connections to the study of finite $p$-groups, and discuss what can be deduced from these finite Dirichlet polynomials.
