Subjects: subject: High Energy Physics - Theory (hep-th)

description: We derive a family of matrix models which encode solutions to the Seiberg-Witten theory in 4 and 5 dimensions. Partition functions of these matrix models are equal to the corresponding Nekrasov partition functions, and their spectral curves are the Seiberg-Witten curves of the corresponding theories. In consequence of the geometric engineering, the 5-dimensional case provides a novel matrix model formulation of the topological string theory on a wide class of non-compact toric Calabi-Yau manifolds. This approach also unifies and generalizes other matrix models, such as the Eguchi-Yang matrix model, matrix models for bundles over $P^1$, and Chern-Simons matrix models for lens spaces, which arise as various limits of our general result.

description: The nuclear physics experiments at the Thomas Jefferson National Accelerator Facility often require longitudinally polarized electrons to be simultaneously delivered to three experimental halls. The degree of longitudinal polarization to each hall varies as function of the accelerator settings, making it challenging in certain situations to deliver a high degree of longitudinal polarization to all the halls simultaneously. Normally, the degree of longitudinal polarization the halls receive is optimized by changing the initial spin direction at the beginning of the machine with a Wien filter. Herein, it is shown that it is possible to further improve the degree of longitudinal polarization for multiple experimental halls by redistributing the energy gain of the CEBAF linacs while keeping the total energy gain fixed.

title: A Qualitative Exploration of the Current State of Observation and Feedback in the Seminaries and Institutes of Religion of the Church of Jesus Christ of Latter-day Saints

description: While the Seminaries and Institutes of Religion (S&I) of The Church of Jesus Christ of Latter-day Saints expect supervisors of teachers to observe teachers regularly and provide feedback, they have not provided those supervisors with adequate training materials, or explained how these supervisors are expected to accomplish this. For this study, three administrators and three teachers were interviewed about their experiences with observation and feedback in S&I. Their responses provided clarification on the purposes of observation and feedback, revealed that a lack of supervisor training has resulted in teachers’ experiences with observation and feedback being different from administrator’s expectations in key ways, and identified some elements of observation and feedback that teachers and administrators agree are effective. Those elements include teachers’ autonomy, collaboration between supervisors, frequent observations designed to help teachers improve (rather than to judge teachers’ abilities), and providing feedback in a kind and constructive way, limiting suggestions for improve to one or two things that are based on principles for teaching that are widely-accepted throughout S&I. This study also reports how teachers and administrators might feel about the use of a standard observation form for teacher observation and feedback.
Environmental weathering of natural and artificial stones used in historical architecture: influence of microstructure and new restoration methods

description: For some study cases (the Cathedral of Modena, Italy, XII-XIV century; the Ducal Palace in Mantua, Italy, XVI century; the church of San Francesco in Fano, Italy, XIV-XIX century), considered as representative of the use of natural and artificial stones in historical architecture, the complex interaction between environ-mental aggressiveness, materials’ microstructural characteristics and degradation was investigated. From the results of such analyses, it was found that materials microstructure plays a fundamental role in the actual extent to which weathering mechanisms affect natural and artificial stones.
Consequently, the need of taking into account the important role of material microstructure, when evaluating the environmental aggressiveness to natural and artificial stones, was highlighted. Therefore, a possible quantification of the role of microstructure on the resistance to environmental attack was investigated. By exposing stone samples, with significantly different microstructural features, to slightly acidic aqueous solutions, simulating clean and acid rain, a good correlation between weight losses and the product of carbonate content and specific surface area (defined as the “vulnerable specific surface area”) was found.
Alongside the evaluation of stone vulnerability, the development of a new consolidant for weathered carbonate stones was undertaken. The use of hydroxya-patite, formed by reacting the calcite of the stone with an aqueous solution of di-ammonium hydrogen phosphate, was found to be a promising consolidating tech-nique for carbonates stones. Indeed, significant increases in the mechanical prop-erties can be achieved after the treatment, which has the advantage of simply con-sisting in a non-hazardous aqueous solution, able to penetrate deeply into the stone (> 2 cm) and bring significant strengthening after just 2 days of reaction. Furthermore, the stone sorptivity is not eliminated after treatment, so that water and water vapor exchanges between the stone and the environment are not com-pletely blocked.

description: Interferometry provides one of the possible routes to ultra-high angular resolution for X-ray and gamma-ray astronomy. Sub-micro-arc-second angular resolution, necessary to achieve objectives such as imaging the regions around the event horizon of a super-massive black hole at the center of an active galaxy, can be achieved if beams from parts of the incoming wavefront separated by 100s of meters can be stably and accurately brought together at small angles. One way of achieving this is by using grazing incidence mirrors. We here investigate an alternative approach in which the beams are recombined by optical elements working in transmission. It is shown that the use of diffractive elements is a particularly attractive option. We report experimental results from a simple 2-beam interferometer using a low-cost commercially available profiled film as the diffractive elements. A rotationally symmetric filled (or mostly filled) aperture variant of such an interferometer, equivalent to an X-ray axicon, is shown to offer a much wider bandpass than either a Phase Fresnel Lens (PFL) or a PFL with a refractive lens in an achromatic pair. Simulations of an example system are presented.

description: In rotating magnetospheres planted on compact objects, there usually exist lightcylinders (LC), beyond which the rotation speed of the magnetic field lines exceeds the speed of light. The LC is a close analog to the horizon in gravity, and is a casual boundary for charged particles that are restricted to move along the magnetic field lines. In this work, it is proposed that there should be Hawking-like radiation of charged particles from the LC of a rotating magnetosphere from the point of view of tunneling by using the field sheet metric.

description: It is of utmost importance that students diagnosed with Autism Spectrum Disorder (ASD) in the public school setting across the United States are receiving the best, most researched services and treatments. This study aimed to find out what services and treatments are most commonly being used for students with ASD in the public schools, to see whether or not those practices are supported by research, and to discover how involved parents and families are in the services being provided to their students. This study found that of the top 25 most commonly used practices, 17 of those were supported by and recommended by research, 3 are considered to have some research support, 1 was considered to not have research support, and 4 were undetermined to have research support. This study also found that overall, parents are aware of the services being provided to their students with ASD, but they do not feel like they are actively involved with majority of the services being provided.

description: Following the recent discovery of gamma rays from the radio-loud narrow-line Seyfert 1 galaxy PMN J0948+0022 (z=0.5846), we started a multiwavelength campaign from radio to gamma rays, which was carried out between the end of March and the beginning of July 2009. The source displayed activity at all the observed wavelengths: a general decreasing trend from optical to gamma-ray frequencies was followed by an increase of radio emission after less than two months from the peak of the gamma-ray emission. The largest flux change, about a factor of about 4, occurred in the X-ray band. The smallest was at ultraviolet and near-infrared frequencies, where the rate of the detected photons dropped by a factor 1.6-1.9. At optical wavelengths, where the sampling rate was the highest, it was possible to observe day-scale variability, with flux variations up to a factor of about 3. The behavior of PMN J0948+0022 observed in this campaign and the calculated power carried out by its jet in the form of protons, electrons, radiation and magnetic field are quite similar to that of blazars, specifically of flat-spectrum radio quasars. These results confirm the idea that radio-loud narrow-line Seyfert 1 galaxies host relativistic jets with power similar to that of average blazars.

description: The Ecosystem Approach to Fisheries represents the most recent research line in the international context, showing interest both towards the whole community and toward the identification and protection of all the “critical habitats” in which marine resources complete their life cycles.
Using data coming from trawl surveys performed in the Northern and Central Adriatic from 1996 to 2010, this study provides the first attempt to appraise the status of the whole demersal community. It took into account not only fishery target species but also by-catch and discharge species by the use of a suite of biological indicators both at population and multi-specific level, allowing to have a global picture of the status of the demersal system. This study underlined the decline of extremely important species for the Adriatic fishery in recent years;  adverse impact on catches is expected for these species in the coming years, since also minimum values of recruits recently were recorded. Both the excessive exploitation and environmental factors affected availability of resources.
Moreover both distribution and nursery areas of the most important resources were pinpointed by means of geostatistical methods. The geospatial analysis also confirmed the presence of relevant recruitment areas in the North and Central Adriatic for several commercial species, as reported in the literature. The morphological and oceanographic features, the relevant rivers inflow together with the mosaic pattern of biocenoses with different food availability affected the location of the observed relevant nursery areas.

description: Abstract

Rare earth elements have become indispensable raw materials for advanced technologies in developed countries, appearing in most high-tech products. Since the 1960s, scientists in Vietnam have conducted research on the application of rare earth elements in various fields, including agriculture, permanent magnet manufacturing, and steel alloying. However, the exploitation and export of rare earth elements in Vietnam have not fully tapped into their potential and remain at a small scale. Moreover, Vietnam lacks the capability to deeply process rare earth elements and separate each individual element, primarily exporting these resources in the form of low-value ore. However, the exploitation of rare earth elements also leads to various issues such as environmental pollution and the decline of biodiversity. This research aims to analyze the opportunities and challenges and provide solutions for Vietnam in its current ownership of rare earth resources.

title: What Resources Do School Librarians Use When Developing New Programming: A Qualitative Inquiry
Creators: name: Hansen, Jennifer
Publisher: name: Utah State University

description: For this qualitative analysis, I analyzed observational and interview data from two middle school librarians setting up new active learning programs. I focused my research by analyzing the preliminary data gathered in field notes from observations at the different library sites to determine what programming resources the librarians were using. A secondary consideration was drawn from preliminary evidence, which indicated the librarians turned to many on and offline information resources, including the social curating site Pinterest. After gathering initial data from observations, I gathered additional data from two interviews: the first interview focused on where the librarians find information and the second interview focused on Pinterest. The data suggests networking within the school community is an essential feature of middle school libraries and should be considered when developing programs as a way to strengthen the librarian’s relationship with the school community, enabling the librarian to leverage other teachers’ knowledge. Also, the curating resources available through Pinterest provide a platform for finding ideas suitable for adapting to a specific library.

description: Systems whose entities interact with each other are common. In many interacting systems, it is difficult to observe the relations between entities which is the key information for analyzing the system. In recent years, there has been increasing interest in discovering the relationships between entities using graph neural networks. However, existing approaches are difficult to apply if the number of relations is unknown or if the relations are complex. We propose the DiScovering Latent Relation (DSLR) model, which is flexibly applicable even if the number of relations is unknown or many types of relations exist. The flexibility of our DSLR model comes from the design concept of our encoder that represents the relation between entities in a latent space rather than a discrete variable and a decoder that can handle many types of relations. We performed the experiments on synthetic and real-world graph data with various relationships between entities, and compared the qualitative and quantitative results with other approaches. The experiments show that the proposed method is suitable for analyzing dynamic graphs with an unknown number of complex relations.

description: The Communist Party of China CCP) controls all political, economic, and military issues in China. In the absence of elections, the only route of recruitment at higher levels of the political hierarchy in the Party is an official promotion. The scholarship on promotions offers two main explanations for advancement inside the Communist Party of China: (i) informal connections between high officials and candidates, and (ii) merit of candidates. This scholarship disregards, however, the importance of achievement of political targets by the candidates, specifically, their ability to deliver social stability.
Like every authoritarian regime, the CCP faces threats from the masses over which the elites rule. Reducing social mobilization is a key component of the CCP’s rule. In the past decade, labor strikes have become offensive in nature with workers demanding better conditions and espousing democratic values, thus challenging the Party’s dominant position in Chinese society. In order to minimize collective activities of Chinese citizens, provincial officials use censorship of the media, including posts on the social media websites, threats of job termination, as well as threats of deportation from urban areas. For that reason, those provincial officials who minimize the number of labor protests increase their chance of promotion to the Politburo. Furthermore, avoiding unrest should matter more for the promotion of party secretaries than governors, whose domain is economic growth.
To evaluate my argument, I analyze promotions of provincial leaders to the Politburo in 2003-2017. The data yield that—consistent with my argument—provincial leaders’ ability to minimize labor strikes increases their chances of promotion. In addition, positive economic performance matters more for the promotion of governors than of party secretaries.

description: Abstract

Innovative market for energy have undergone a transformation with the introduction of smart grids, which enable users to participate in demand response (DR) programs and achieve a balance between energy supply and demand. It can be difficult for users to respond to DR signals since they are typically less aware of what to do when they get one. With the use of DR signals, energy management controllers, or EMCs, were developed to automatically solve energy management issues. Rather than turning off a feeder, we have solved this issue automatically or from the smart grid by controlling individual loads using Arduino, ESP-8266, relays, and an online application or website. With this EMC integration into our current network, we will be able to remotely adjust load, lower the cost of electricity per unit, enhance power quality, and prevent peaks during off-peak hours. As a consequence, we were able to accomplish our necessary goals with our current infrastructure by using hardware and software solutions.

The abuse of intellectual property rights and regulations in China: a law and economic analysis

description: From the institutional point of view, the legal system of IPR (intellectual property right, hereafter, IPR) is one of incentive institutions of innovation and it plays very important role in the development of economy. According to the law, the owner of the IPR enjoy a kind of exclusive right to use his IP(intellectual property, hereafter, IP), in other words, he enjoys a kind of legal monopoly position in the market. 
How to well protect the IPR and at the same time to regulate the abuse of IPR is very interested topic in this knowledge-orientated market and it is the basic research question in this dissertation.
In this paper, by way of comparing study and by way of law and economic analyses, and based on the Austrian Economics School’s theories, the writer claims that there is no any contradiction between the IPR and competition law. However, in this new economy (high-technology industries), there is really probability of the owner of IPR to abuse his dominant position. And with the characteristics of the new economy, such as, the high rates of innovation, “instant scalability”, network externality and lock-in effects, the IPR “will vest the dominant undertakings with the power not just to monopolize the market but to shift such power from one market to another, to create strong barriers to enter and, in so doing, granting the perpetuation of such dominance for quite a long time.”1 Therefore, in order to keep the order of market, to vitalize the competition and innovation, and to benefit the customer, in EU and US, it is common ways to apply the competition law to regulate the IPR abuse. In Austrian Economic School perspective, especially the Schumpeterian theories, the innovation/competition/monopoly and entrepreneurship are inter-correlated, therefore, we should apply the dynamic antitrust   model based on the AES theories to analysis the relationship between the IPR and competition law.
   China is still a developing country with relative not so high ability of innovation. Therefore, at present, to protect the IPR and to make good use of the incentive mechanism of IPR legal system is the first important task for Chinese government to do. However, according to the investigation reports,2 based on their IPR advantage and capital advantage, some multinational companies really obtained the dominant or monopoly market position in some aspects of some industries, and there are some IPR abuses conducted by such multinational companies. And then, the Chinese government should be paying close attention to regulate any IPR abuse. However, how to effectively regulate the IPR abuse by way of competition law in Chinese situation, from the law and economic theories’ perspective, from the legislation perspective, and from the judicial practice perspective, there is a long way for China to go!

description: Through the vantage point of institutions of higher learning, Utah's distinction as a politically conservative state dominated by the Church of Jesus Christ of Latter-day Saints is examined during the Vietnam War era. The three universities in the study-Brigham Young University, University of Utah, and Utah State University- are the three oldest and most populous universities in the state. This thesis concentrates on these three institutions and less on the politics of the state at the time. Studies showed that the universities, to varying degrees, exhibited antiwar sentiment Still, the campuses were less active in opposing the war, drawing only a very small percentage of students to demonstrations.
Brigham Young University's President, Ernest L. Wilkinson (1951-1971), vigorously guarded against signs of antiwar activity. He was involved in the 1966 spy ring, which organized students for surveillance of supposedly liberal faculty. Students who appeared to be antiwar were also scrutinized. Despite the negative sanctions on such students, a minority of pupils did oppose the war and Wilkinson's tactics.
The University of Utah produced the highest number of protesters, largely because of its more diverse and urban population. Many of the demonstrators at the U of U continued as activists in the Salt Lake Valley into the 1990s. Utah State University echoed the U of U, but to a lesser extent. Still, underground newspapers and an organized antiwar political party showed that USU also had a movement against the war. The administrations of the two schools figure into the text less powerfully than BYU's Wilkinson because they failed to become as involved in the debate.
Oral interviews dominate this thesis. Subjects were chosen according to their involvement in particular events or movements. Student newspapers and underground newspapers were also utilized.
This thesis attempted to recreate a tumultuous and turbulent time in American history. Utah's unique cultural slant showed that the Beehive State could not isolate itself from international events but also responded in its own way.

Three different estimation procedures-the method of moments, maximum likelihood, and a hybrid of these two methods, which we call the one-step improvement-were compared by computer simulation, for beta data and beta data contaminated by zeros and ones. We also evaluated maximum likelihood estimation in the context of censored data, and Newton's method as a numerical procedure for solving the likelihood equations for censored beta data.

description: Digital synoptic sky surveys pose several new object classification challenges. In surveys where real-time detection and classification of transient events is a science driver, there is a need for an effective elimination of instrument-related artifacts which can masquerade as transient sources in the detection pipeline, e.g., unremoved large cosmic rays, saturation trails, reflections, crosstalk artifacts, etc. We have implemented such an Artifact Filter, using a supervised neural network, for the real-time processing pipeline in the Palomar-Quest (PQ) survey. After the training phase, for each object it takes as input a set of measured morphological parameters and returns the probability of it being a real object. Despite the relatively low number of training cases for many kinds of artifacts, the overall artifact classification rate is around 90%, with no genuine transients misclassified during our real-time scans. Another question is how to assign an optimal star-galaxy classification in a multi-pass survey, where seeing and other conditions change between different epochs, potentially producing inconsistent classifications for the same object. We have implemented a star/galaxy multipass classifier that makes use of external and a priori knowledge to find the optimal classification from the individually derived ones. Both these techniques can be applied to other, similar surveys and data sets.

description: Self-consistent solutions for triaxial mass models are highly non-unique. In general, some of these solutions might be dynamically unstable, making them inappropriate as descriptions of steady-state galaxies. Here we demonstrate for the first time the existence in triaxial galaxy models of an instability similar to the radial-orbit instability of spherical models. The instability manifests itself when the number of box orbits, with predominantly radially motions, is sufficiently large. N-body simulations verify that the evolution is due neither to chaotic orbits nor to departures of the model from self-consistency, but rather to a collective mode. The instability transforms the triaxial model into a more prolate, but still triaxial, configuration. Stable triaxial models are obtained when the mass contribution of radial orbits is reduced. The implications of our results for the shapes of dark-matter halos are discussed.

This study aimed to investigate the influence of vocational teachers' personality traits on their teaching effectiveness, with a specific emphasis on the mediating role of job stress in this dynamic. Conducted across several higher vocational colleges and universities in Hebei Province, China, the research involved a sample of approximately 380 vocational teachers. The methodological approach utilized the Big Five Inventory to assess personality traits, the Teaching Effectiveness Scale to evaluate teaching effectiveness, and the Job Stress Scale to measure levels of job-related stress. The results of this study underscore the considerable impact that personality traits, particularly conscientiousness, exert on teaching effectiveness among vocational teachers. Moreover, job stress was identified as a significant mediator in the relationship between personality traits and teaching effectiveness. This indicates that elevated levels of job stress can undermine the positive contributions of teachers' personality traits to their effectiveness in teaching roles. Consequently, these findings underscore the critical interplay between personality traits and job stress in determining the quality of teaching and learning within vocational education settings. The insights garnered from this research offer valuable guidance for the formulation of policies and practices aimed at enhancing the quality of vocational education. In particular, the findings suggest the need for strategies that not only recognize the importance of fostering desirable personality traits among vocational teachers but also address the mitigating effects of job stress on teaching effectiveness. Given that the study was situated within the context of higher vocational colleges and universities in Hebei Province, its conclusions are especially pertinent to the unique challenges and opportunities inherent in China's vocational education sector. As such, these results provide critical direction for ongoing educational reforms and teacher development initiatives, thereby contributing to the advancement of vocational education quality in China.

description: Several wavelet techniques in the analysis of time series are developed and applied to real data sets.
Methods for long-memory models include wavelet-based confidence intervals for the self-similarity para meter in potentially heavy-tailed observations. Empirical coverage probabilities are used to assess the procedures by applying them to Linear Fractional Stable Motion with many choices of para meters. Asymptotic confidence intervals provide empirical coverage often much lower than nominal and it is recommended to use subsampling confidence intervals. A procedure for monitoring the constancy of the self-similarity parameter is proposed and applied to Ethernet data sets.
A test to distinguish a weakly dependent time series with a trend component, from a long-memory process, possibly with a trend, is proposed. The test uses a generalized likelihood ratio statistic based on wavelet domain likelihoods. The test is robust to trends that are piecewise polynomials. The empirical size and power are good and do not depend on specific choices of wavelet functions and models for the wavelet coefficients. The test is applied to annual minima of the water levels of the Nile River and confirms the presence of long-range dependence in this time series.
A wavelet-based method of computing an index of geomagnetic storm activity is put forward. The new index can be computed automatically using statistical procedures and does not require operator's intervention in selecting quiet days and removal of the secular component by polynomial fitting. This one-minute index is designed to facilitate the study of the fine structure of geomagnetic storm events and requires only the most recent magnetogram records, e.g., the two months including the storm event of interest. It can thus be computed over a moving window as soon as new magnetogram records become available. Averaged over one-hour periods, it is practically indistinguishable from the traditional Dst index.

description: We investigate whether 4-dimensional static and cosmological Lifshitz solutions can be found from deforming the existing (A)dS_4 compactifications in IIA and IIA* supergravity. Using a well motivated compactification Ansatz on SU(3)-structure manifolds with 19 undetermined parameters we demonstrate that this is not the case in ordinary IIA supergravity, thereby generalising previous nogo results in different ways. On the other hand, for IIA* we construct explicit cosmological Lifshitz solutions. We also consider solutions with non-constant scalars and are able to find simple static and cosmological Lifshitz solutions in IIB* supergravity and a Euclidean Lifshitz solution in ordinary Euclidean IIB supergravity, which is similar to a non-extremal deformation of the D-instanton. The latter solutions have z=-2.

description: The atmospheric muon charge ratio, defined as the number of positive over negative charged muons, is an interesting quantity for the study of high energy hadronic interactions in atmosphere and the nature of the primary cosmic rays. The measurement of the charge ratio in the TeV muon energy range allows to study the hadronic interactions in kinematic regions not yet explored at accelerators. 
The OPERA experiment is a hybrid electronic detector/emulsion apparatus, located in the underground Gran Sasso Laboratory, at an average depth of 3800 meters water equivalent (m.w.e.). OPERA is the first large magnetized detector that can measure the muon charge ratio at the LNGS depth, with a wide acceptance for cosmic ray muons coming from above. 
In this thesis, the muon charge ratio is measured using the spectrometers of the OPERA detector in the highest energy region.
The charge ratio was computed separately for single and for multiple muon events, in order to select different primary cosmic ray samples in energy and composition. The measurement as a function of the surface muon energy is used to infer parameters characterizing the particle production in atmosphere, that will be used to constrain Monte Carlo predictions. 
Finally, the experimental results are interpreted in terms of cosmic ray and particle physics models.

description: Single photons detected by the DELPHI experiment at LEP2 in the years 1997-2000 are reanalysed to investigate the existence of a single extra dimension in a modified ADD scenario with slightly warped large extra dimensions. The data collected at centre-of-mass energies between 180 and 209 GeV for an integrated luminosity of ~650 pb^{-1} agree with the predictions of the Standard Model and allow a limit to be set on graviton emission in one large extra dimension. The limit obtained on the fundamental mass scale M_D is 1.69 TeV/c^2 at 95% CL, with an expected limit of 1.71 TeV/c^2.

description: This dissertation uses the concept of “precariousness” to analyze women’s labour conditions in Italian industry over the Fifties and Sixties, when the agricultural basis of the Italian economy was replaced by an industrial one. The present research studies the way in which female work has been employed on different and nearly always inferior terms to male work, whether quantitatively or qualitatively. In most cases wages have been lower, periods of qualification and dequalification more unfavourable, and contract terms generally less secure than for male workers. The combination of these aspects of women work conditions has resulted in what will be called job precariousness. 
Job precariousness is adopted as a paradigm for an in-depth analysis of women’s working conditions. Women (like immigrants) have always experienced considerably worse working conditions than men throughout the capitalist industrial age. Even in the “Golden Age” of the 20th century (1945-1975), considered by most sociologists and economists “the era of job stability”, women’s working conditions were worse than men’s and can be defined precarious. Women in Bolognese industry are not an exception. The dissertation will show how many women’s jobs in industry were the opposite of stable and therefore can be called precarious in the period of 1950s and 1960s, when the Italian economy experienced the most intense economic and industrial growth of the 20th century. The comparison between female and male work conditions will address several aspects related to job precariousness: duration and continuity of work, salary variability, forms of discrimination and the relation between contract and social rights. In addition, attention will be paid to the forms of contract, gender-specific forms of discrimination and material working conditions of women.
