Singlet-Doublet Dirac Dark Matter
Creators: name: Yaguna, Carlos E.
Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We analyze a simple extension of the Standard Model where the dark matter particle is a Dirac fermion that is mixture of a singlet and an SU(2) doublet. The model contains only four free parameters: the singlet and the doublet masses and two new Yukawa couplings. Direct detection bounds in this model are very strong and require the dark matter particle to be singlet-like. As a result, its relic density has to be obtained via coannihilations with the doublet. We find that the dark matter mass should be below 750 GeV, that the singlet-doublet mass difference cannot exceed 9%, and that direct detection experiments offer the best chance to probe this scenario. Finally, we also show that this model can effectively arise in well-motivated extensions of the Standard Model.

description: The purpose of this thesis is to develop an operational algorithm for designing a system that efficiently harnesses energy from photovoltaic panels, ensuring self-sufficiency within the system. Excess energy is used for hydrogen production through water electrolysis to meet specific annual targets. The energy management algorithm is explained, taking the State Of Charge (SOC) of the battery into consideration as a control variable. It determines the operational conditions for all system components to ensure their optimal performance. Finally, an optimization package in Matlab is employed to determine the optimal sizes for subsystems (photovoltaic panels, batteries, and electrolysis units). Based on this algorithm and meteorological data for the Anogia and Tavronitis region, various scenarios are explored to fulfill the energy requirements of specific communities, while simultaneously achieving defined H2 production targets.

description: The combination of gender bias and gender stereotypes in children's literature has been analyzed for the past fifty years by numerous researchers. Despite the scrutiny, the research continues to find that females are often under-represented, and both male and female characters display stereotypical traits. In an effort to shape children's attitudes, it has been suggested that it is important to incorporate literature in the classroom that portrays females and males equitably and reflects nontraditional roles and responsibilities. The majority of studies have examined children's picture books through the analysis of title, text, and illustrations. In this study, the titles, main characters, and text of novels considered for use in one North Carolina county's middle school curriculum were analyzed for gender bias and stereotypes. The results showed an under-representation of females as main characters and of males with feminine gender traits.

description: The Office of International Student and Scholar Services (ISSS), is the administrative
office that serves international students, research scholars, and visiting professors at the
University of North Carolina at Chapel Hill. ISSS spent the fall 2013 - spring 2014
academic school year redesigning their website using user-centered design methodologies
with the assistance of a SILS graduate student. User-centered design is an approach
where the needs and requirements of the users are put in focus throughout each stage of
the design process. This study describes how user-centered design principles were
incorporated into the final design of the website.
In addition, this study examines to see if incorporating user-centered design
methodologies in the redesign of the website can allow for international students to
successfully complete common tasks on the website at an above average user task
completion rate of 80% or above. The study tested the task completion rate by conducting
a series of user-testing sessions on the redesigned ISSS website with eight UNC
international students.

description: Many variables can affect how user populations behave online, including the environment in which people are accessing the Internet, their familiarity with the Internet in general, and their familiarity with the specific site that they are navigating.  This study uses usage data gathered from the Internet Public Library combined with census data to analyze the behavior of visitors to the site from North Carolina.  The census data shows that the behavior of user groups varies according to socioeconomic variables such as median household income and the percentage of the county population with a post-high school education.  While libraries already make efforts to understand their user populations by examining available demographic information, the relationships revealed between variables in this study can aid in further understanding the behavior of population groups.

In this paper we present a proof for the Laguerre and Jacobi cases. Their bispectral properties are also discussed, which give a method to obtain the coefficients of the recurrence relations explicitly. This paper extends to the Laguerre and Jacobi cases the bispectral techniques recently introduced by Gómez-Ullate et al. to derive explicit expressions for the coefficients of the recurrence relations satisfied by exceptional polynomials of Hermite type.

Vesicular trafficking dynamics enable context-dependent regulation of ErbB receptor activity and signaling

description: The ErbB signaling network comprises a complex dynamic system, which regulates a diverse set of cellular behaviors. In this thesis, we examined how regulating the distribution of ErbB receptors between the plasma membrane and different endosomal compartments enables contextual regulation of receptor activity and signaling. In the first part of this work, we investigated how spatial regulation of EGFR controls its autocatalytic activity. We found that autonomously activated and EGF activated receptors are processed differently by the endocytic machinery. Constitutive vesicular recycling through perinuclear areas with high PTP1B phosphatase activity suppresses autonomous receptor activation in the absence of ligand, while maintaining EGFR abundance at the PM. In contrast, EGF binding enhances EGFR self-association and phosphorylation of the c-Cbl docking tyrosine Y1045, which results in receptor ubiquitination, internalization and lysosomal degradation. The coupling of EGFR self-association state, ubiquitination and vesicular dynamics thereby allows for the coexistence of a continuous safeguard cycle, while maintaining sensitivity to growth factor stimulation.In the second part of this work, we examined how ligand-specific ErbB receptor trafficking determines Erk signaling dynamics and localization. We found that EGF or heregulin (HRG) differentially modulate ErbB receptor trafficking to generate distinct spatiotemporal patterns of receptor activities, leading to the activation of Erk from different subcellular compartments (plasma membrane and endosomes). The subcellular localization of Erk activation influences its interaction with different effector proteins and thereby generates ligand-specific cellular responses. Proliferative Erk signals are transmitted to the nucleus, irrespective of their spatial origin, while the Erk dependent phosphorylation of pro-migratory effectors relies on membrane proximal Erk activity. Collectively our findings highlight how vesicular dynamics enable context dependent spatial regulation of ErbB activity and downstream signaling events.

Anharmonic stabilization and band gap renormalization in the perovskite CsSnI$_3$

description: Amongst the X(Sn,Pb)Y$_3$ perovskites currently under scrutiny for their photovoltaic applications, the cubic B-$α$ phase of CsSnI$_3$ is arguably the best characterized experimentally. Yet, according to the standard harmonic theory of phonons, this deceptively simple phase should not exist at all due to rotational instabilities of the SnI$_6$ octahedra. Here, employing self-consistent phonon theory we show that these soft modes are stabilized at experimental conditions through anharmonic phonon-phonon interactions between the Cs ions and their iodine cages. We further calculate the renormalization of the electronic energies due to vibrations and find an unusual opening of the band gap, estimated as 0.24 and 0.11 eV at 500 and 300 K, which we attribute to the stretching of Sn-I bonds. Our work demonstrates the important role of temperature in accurately describing these materials.

description: We consider the decay of "false kinks," that is, kinks formed in a scalar field theory with a pair of degenerate symmetry-breaking false vacua in 1+1 dimensions. The true vacuum is symmetric. A second scalar field and a peculiar potential are added in order for the kink to be classically stable. We find an expression for the decay rate of a false kink. As with any tunneling event, the rate is proportional to $\exp(-S_E)$ where $S_E$ is the Euclidean action of the bounce describing the tunneling event. This factor varies wildly depending on the parameters of the model. Of interest is the fact that for certain parameters $S_E$ can get arbitrarily small, implying that the kink is only barely stable. Thus, while the false vacuum itself may be very long-lived, the presence of kinks can give rise to rapid vacuum decay.

description: This study examines whether the humor forms found in children's picture books published within the last five years meet the cognitive needs of the preschool-age child.  A review of the literature on cognitive development and the stages of humor development will shed light on what types of humor are understood and appreciated by three to seven year olds from a developmental perspective. A sample of humorous picture books was selected for analysis and coded with the types of humor present in each. The results reveal that pictures books are using developmentally appropriate types of humor, although types of humor relevant for younger or older stages of development are also found in the samples.

description: When students write research papers they use a variety of sources in their paper. These sources range from web pages to research articles. The purpose of this study was to decide whether or not undergraduate students would choose to use scholarly or non-scholarly sources when presented with both types of sources in a set of search results. Twenty Duke University students were recruited for the study. They were given a research topic and asked to perform a search. Both the search results and interface were fabricated by the researcher in order to control the experimental environment. The students were asked to rate the sources found in the results, choose four sources to use for their research scenario, and finally, were asked to explain reasoning behind their choices. The findings concluded that the students in this study were more likely to choose scholarly sources over non-scholarly sources and give these scholarly sources higher ratings.

Quasi-Monte Carlo integration using digital nets with antithetics

Publisher: name: arXiv

Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: Antithetic sampling, which goes back to the classical work by Hammersley and Morton (1956), is one of the well-known variance reduction techniques for Monte Carlo integration. In this paper we investigate its application to digital nets over $\mathbb{Z}_b$ for quasi-Monte Carlo (QMC) integration, a deterministic counterpart of Monte Carlo, of functions defined over the $s$-dimensional unit cube. By looking at antithetic sampling as a geometric technique in a compact totally disconnected abelian group, we first generalize the notion of antithetic sampling from base $2$ to an arbitrary base $b\ge 2$. Then we analyze the QMC integration error of digital nets over $\mathbb{Z}_b$ with $b$-adic antithetics. Moreover, for a prime $b$, we prove the existence of good higher order polynomial lattice point sets with $b$-adic antithetics for QMC integration of smooth functions in weighted Sobolev spaces. Numerical experiments based on Sobol' point sets up to $s=100$ show that the rate of convergence can be improved for smooth integrands by using antithetic sampling technique, which is quite encouraging beyond the reach of our theoretical result and motivates future work to address.

description: We study the deformations of a smooth curve $C$ on a smooth projective threefold $V$, assuming the presence of a smooth surface $S$ satisfying $C \subset S \subset V$. Generalizing a result of Mukai and Nasu, we give a new sufficient condition for a first order infinitesimal deformation of $C$ in $V$ to be primarily obstructed. In particular, when $V$ is Fano and $S$ is $K3$, we give a sufficient condition for $C$ to be (un)obstructed in $V$, in terms of $(-2)$-curves and elliptic curves on $S$. Applying this result, we prove that the Hilbert scheme $\operatorname{Hilb}^{sc} V_4$ of smooth connected curves on a smooth quartic threefold $V_4$ contains infinitely many generically non-reduced irreducible components, which are variations of Mumford's example for $\operatorname{Hilb}^{sc} \mathbb P^3$.

description: Materials science is a highly active research area, covering a broad range of topics. Many communities exist which focus on specific aspects; despite their differences, all of them acknowledge the need of establishing good data management practices following the FAIR principles (Findability, Accessibility, Interoperability, Reusability). This presentation highlights the results achieved so far in this area by three research projects: the NFFA (Nanoscience Foundries and Fine Analysis)-Europe Pilot, the German Joint Lab MDMC (integrated Model and Data-driven Materials Characterization), and the German consortium NFDI-MatWerk (National Research Data Infrastructure for Materials Science and Engineering). The commonalities among them, particularly in terms of requirements, tools and infrastructure solutions are showcased. These success stories underscore the crucial importance of aligning data management activities across multiple communities, in order to enable interdisciplinary collaborations and facilitate efficient data sharing and reuse.
The Chronically Ill Child: A Content Analysis Assessing the Realistic Portrayal of the "Illness Experience" for Child Characters in 21st Century Children's Picture Books

Content analysis--Children's literature

description: The growing realism that has emerged in children's literature in the past several decades has made it possible for more complicated topics such as chronic illness to be considered.  Despite the growing presence of illness in children's literature, chronically ill characters are still vastly underrepresented and are often portrayed negatively or only partially.  This remains true even as more children are diagnosed yearly with a chronic condition.
Research suggests that for children's literature featuring chronically ill characters to be valuable to its young readers, it must be reflective of the realistic emotions and behaviors chronically ill people experience.  The "illness experience" has been defined in this paper by medical, social, and emotional factors.  The following content analysis considers whether twenty children's picture books published since 2000 realistically present the illness experience of childhood chronic illness.

description: The activity of two chlorinated isocyanurates (NaDCC and TCCA) and peroxymonosulphate (OXONE) was evaluated against biofilms of Stenotrophomonas maltophilia, an emerging pathogen isolated from drinking water (DW), and for the prevention of biofilm regrowth. After disinfection of pre-formed 48 h-old biofilms, the culturability was reduced up to 7 log, with OXONE, TCCA, and NaDCC showing more efficiency than free chlorine against biofilms formed on stainless steel. The regrowth of biofilms previously exposed to OXONE was reduced by 5 and 4 log CFU cm−2 in comparison to the unexposed biofilms and biofilms exposed to free chlorine, respectively. Rheometry analysis showed that biofilms presented properties of viscoelastic solid materials, regardless of the treatment. OXONE reduced the cohesiveness of the biofilm, given the significant decrease in the complex shear modulus (G*). AFM analysis revealed that biofilms had a fractured appearance and smaller bacterial aggregates dispersed throughout the surface after OXONE exposure than the control sample. In general, OXONE has been demonstrated to be a promising disinfectant to control DW biofilms, with a higher activity than chlorine. The results also show the impact of the biofilm mechanical properties on the efficacy of the disinfectants in biofilm control.

description: Distance education has become an important part of college and university academic programs in recent years, potentially impacting millions of students in higher education each year. This study sought to learn what distance learners use to find information for class research, and how much a library's distance education services impact the students' academic success. As universities continue to extend their campuses virtually, their libraries must follow suit to remain relevant to today's highly digital educational environment. Support is  needed from the institutions' libraries through dynamic subject guides, online tutorials, etc. to help increase student comprehension of course material. Important issues for libraries and librarians to address include remote access for student research, collaborative planning  with teaching faculty, outreach and marketing to increase awareness of library services and resources, library website integration with course management systems, and assessment of library services for distance learners.

description: Adaptive Kinetic Monte Carlo combines the simplicity of Kinetic Monte Carlo (KMC) with a Molecular Dynamics (MD) based saddle point search algorithm in order to simulate metastable systems. Key to making Adaptive KMC effective is a stopping criterion for the saddle point search. In this work, we examine a recent criterion, due to S. Chill and G. Henkelman, that is based on the fraction of total reaction rate found instead of the fraction of observed saddles. The criterion uses the Eyring-Kramers law to estimate the reaction rate at the MD search temperature. We also consider a related criterion that remains valid when the Eyring-Kramers law is not. We examine the mathematical properties of both estimators and prove their mean square errors are well behaved, vanishing as the simulation continues to run.

description: Bryozoans are commonly associated with various artificial structures in marine environments and have been responsible for several bioinvasion events worldwide. Understanding the interactions between bryozoans and artificial structures is therefore essential to prevent the establishment and spread of potential bioinvaders. This study investigated bryozoan recruitment on four different substrates (PET, nautical ropes, metal, and PVC) placed in three orientations (vertical, horizontal facing down and facing up) in an area of the Western Atlantic. In total, 15 species of bryozoans were found. The results revealed significant variations in assemblages’ richness, with bryozoans showing a preference for settling on PVC (14 species found) and on the underside of horizontal substrates (15 species found), resulting in the higher representativity observed in this study. Cryptogenic (nine species) and exotic (five species) bryozoans dominated the assemblages in all treatments, indicating that the type of substrate (especially artificial) and its orientation can favor the settlement of bryozoans, particularly non-native species. Therefore, the availability of multiple types of artificial substrates in marine environments should be treated as a cause for concern.
The Design and Implementation of a Web-Accessible Database to Integrate with the Existing Information System of Rainbow Soccer, Ltd.

description: This project analyzes and redesigns part of the information system for Rainbow Soccer Ltd. in Chapel Hill, NC. The goal of the project is to optimize the information system in order to gather and disseminate information with greater accuracy and efficiency. Rainbow Soccer's current system primarily consists of a static, informational website accessible to the public. There are two main problems with this system. First, there is not an efficient way for coaches to research field availability. Second, there is no complete, up-to-date master or individual team schedule accessible on the web. The proposed system incorporates a web-accessible database. The database was built in Microsoft Access while the user interface was created using ColdFusion and HTML. This system would allow the Rainbow Soccer staff to publish up-to-date information more easily and would help facilitate information retrieval for its users.
The Local Cut Lemma

description: The Lovász Local Lemma is a very powerful tool in probabilistic combinatorics, that is often used to prove existence of combinatorial objects satisfying certain constraints. Moser and Tardos have shown that the LLL gives more than just pure existence results: there is an effective randomized algorithm that can be used to find a desired object. In order to analyze this algorithm, Moser and Tardos developed the so-called entropy compression method. It turned out that one could obtain better combinatorial results by a direct application of the entropy compression method rather than simply appealing to the LLL. The aim of this paper is to provide a generalization of the LLL which implies these new combinatorial results. This generalization, which we call the Local Cut Lemma, concerns a random cut in a directed graph with certain properties. Note that our result has a short probabilistic proof that does not use entropy compression. As a consequence, it not only shows that a certain probability is positive, but also gives an explicit lower bound for this probability. As an illustration, we present a new application (an improved lower bound on the number of edges in color-critical hypergraphs) as well as explain how to use the Local Cut Lemma to derive some of the results obtained previously using the entropy compression method.
description: 19 pages, 2 figures. This updated version includes a simplified special case of the LCL (Theorem 3.1) which is sufficient for many applications and is, perhaps, somewhat more intuitive

description: This paper discusses the need for coffee shops in academic libraries. It reviews library literature to evaluate the current situation. Students at the University of North Carolina at Chapel Hill, Duke University, and North Carolina State University were surveyed. Libraries at all three campuses provide or allow coffee in their buildings. A questionnaire was used to determine how students are using academic libraries. In addition, they were asked about their coffee drinking habits. After examining the findings, suggestions are made for libraries considering providing a coffee service for their users.
Bogoliubov-de Gennes Soliton Dynamics in Unconventional Fermi Superfluids

description: Exact self-consistent soliton dynamics based on the Bogoliubov-de Gennes (BdG) formalism in unconventional Fermi superfluids/superconductors possessing an $SU(d)$-symmetric two-body interaction is presented. The derivation is based on the ansatz having the similar form as the Gelfand-Levitan-Marchenko equation in the inverse scattering theory. Our solutions can be regarded as a multicomponent generalization of the solutions recently derived by Dunne and Thies [Phys. Rev. Lett. 111, 121602 (2013)]. We also propose superpositions of occupation states, which make it possible to realize various filling rates even in one-flavor systems, and include Dirac and Majorana fermions. The soliton solutions in the $ d=2 $ systems, which describe the mixture of singlet $s$-wave and triplet $p$-wave superfluids, exhibit a variety of phenomena such as SU(2)-DHN breathers, Majorana triplet states, $s$-$p$ mixed dynamics, and so on. These solutions are illustrated by animations, where order parameters are visualized by spherical harmonic functions. The full formulation of the BdG theory is also supported, and the double-counting problem of BdG eigenstates and $N$-flavor generalization are discussed.

Library cooperation

description: This study surveyed school and public youth services librarians to discover the nature of collaboration between their organizations as well as their perceptions of factors that facilitate and act as barriers to collaboration between their institutions. Previous studies have identified a plethora of potential facilitators and barriers to collaboration and cooperation, such as support from managers, colleagues, and fellow collaborators, or a lack of time and money. Recent studies on collaboration between school and public libraries, however, have centered on case studies of successful collaborative endeavors rather than on ways that collaboration might not work between these two organizations. This study builds on the broader survey studies from the past to continue the discussion on the nature of collaboration and its purpose in school and public libraries. It concludes with suggestions for further research on this topic.

description: The totality of information submitted to digital platforms - such as social networks, microblogging services and review platforms - is summarily referred to as user-generated content and encompasses a broad variety of data types, ranging from text and images to audio and video recordings. A key characteristic of user-generated content is that it is both publicly available, as well as easily accessible and collectable in arbitrarily large amounts by anyone who has the necessary know-how and an interest in doing so. Within the context of marketing research, a subset of user-generated content representing consumers sharing their experience with and opinions about products, brands and services is a popular subject of investigation. The diversity and vastness of user-generated content presents several challenges and opportunities to marketing researchers. Accessing, managing and processing the large amounts of data involved requires methodological knowledge traditionally found in the realm of computer science and software engineering and the multitude of different platforms that act as data sources differ in their functioning, each requiring specific knowledge and experience in consequence. The four studies that make up this dissertation cover a wide range of topics and relate to different aspects of marketing in multiple ways and to varying degrees, building upon data collected from a multitude of sources over several years, including reddit, twitter and Twitch. All make use of the excessive amount of publicly available information that user-generated content represents and exemplify some of the ways that companies and marketing professionals can exploit it to better their understanding of the needs of their customers, develop more effective marketing measures and ultimately gain competitive advantage.

description: We propose a scheme for generating three-dimensional entanglement between two atoms trapped in two spatially separated cavities reapectively via shortcuts to adi- abatic passage based on the approach of Lewis-Riesenfeld invariants in cavity quan- tum electronic dynamics. By combining Lewis-Riesenfeld invariants with quantum Zeno dynamics, we can generate three dimensional entanglement of the two atoms with high fidelity. The Numerical simulation results show that the scheme is ro- bust against the decoherences caused by the photon leakage and atomic spontaneous emission.
