description: Most are aware that the curation of archaeological and historical data and associated records has been a challenge for quite some time. Adequate curation of objects and associated records has received significant attention in the past two decades; however, professional archaeologists within academia, the Cultural Resources Management (CRM) industry, and federal and state agencies are keenly aware that we need to do more, if we are to successfully preserve our heritage, advance evidence-based understandings of the human past, and fulfill an obligation to serve as stewards of the archaeological record of human history (e.g., Society for American Archaeology 1996). Archaeologists increasingly recognize that addressing our most pressing social and intellectual problems (Kintigh et al. 2014) demands comparative and synthetic research (Altschul et al. 2018). Archaeology uniquely provides access to the long term social and environmental dynamics that must be understood to address important contemporary problems. Archaeology’s long-term perspective is essential because key processes operate so slowly that they are only perceptible over centuries or millennia. An archaeological perspective illuminates and enables the synthesis of information concerning the initial conditions and the outcomes of thousands of completed social “experiments” in the past. The needed synthetic research critically depends upon access to the vast corpus of archaeological, ethnographic, and historical data that the CRM industry has generated over the last 50 years. If we are to leverage those data to advance our knowledge of the past and for the benefit of the public, the data must reside in repositories where they are easily discovered, accessed, used, and preserved for future uses.

description: In Newtonian gravity, a stationary axisymmetric system admits a third, Carter-like constant of motion if its mass multipole moments are related to each other in exactly the same manner as for the Kerr black-hole spacetime. The Newtonian source with this property consists of two point masses at rest a fixed distance apart. The integrability of motion about this source was first studied in the 1760s by Euler. We show that the general relativistic analogue of the Euler problem, the Bach-Weyl solution, does not admit a Carter-like constant of motion, first, by showing that it does not possess a non-trivial Killing tensor, and secondly, by showing that the existence of a Carter-like constant for the two-center problem fails at the first post-Newtonian order.

description: We address measurements of covariant phase observables (CPOs) by means of realistic eight-port homodyne detectors. We do not assume equal quantum efficiencies for the four photodetectors and investigate the conditions under which the measurement of a CPO may be achieved. We show that balancing the efficiencies using an additional beam splitter allows us to achieve a CPO at the price of reducing the overall effective efficiency, and prove that it is never a smearing of the ideal CPO achievable with unit quantum efficiency. An alternative strategy based on employing a squeezed vacuum as a parameter field is also suggested, which allows one to increase the overall efficiency in comparison to the passive case using only a moderate amount of squeezing. Both methods are suitable for implementantion with current technology.

We frequently reverse orientation of the experiment and search for signals at the first and second harmonics of the sidereal frequency. We constrain 4 of the 5 spatial Lorentz-violating coefficients $c^n_{jk}$ that parameterize anisotropy of the maximum attainable velocity of a neutron at a level of $10^{-29}$, improving previous limits by 2 to 4 orders of magnitude and placing the most stringent constrain on deviations from local Lorentz invariance.

Der Einfluss des Kinderschutzkonzepts auf die Organisationsentwicklung, die Qualität der Betreuung, den Schutz der Kinder und der Mitarbeitenden in der Kita Campus

Publisher: name: Zenodo

description: Kindertagesstätten kommen in letzter Zeit häufiger mit negativen Schlagzeilen bezüglich Übergriffen an Kindern in die Presse. Und wie meine persönliche Erfahrung als Geschäfts- und Kitaleiterin der Kita Campus, Kindertagesstätte der Universität Luzern, der Hochschule Luzern und der Pädagogischen Hoch- schule Luzern zeigt, kann dies jede Kindertagesstätte betreffen. «In einer solchen Situation gibt es immer nur Verlierer», das waren die Worte des Kriminalpolizisten, der am 13. Mai 2013 eine in der Kita Campus beschäftigte Person wegen Verdachts auf sexuellen Übergriff an einem Kind festnahm. Die betreffende Person wurde mit sofortiger Wirkung dauerhaft von der Arbeit suspendiert, später wurde das Strafverfahren wegen Unschuldsvermutung eingestellt. Aufgrund dieses einschneidenden Ereignisses entwickelte die Kita Campus von 2014 – 2015 ein umfassendes individuelles Kinderschutzkonzept, das präventiv und auch im Notfall Leitlinien zum Schutz der Kinder vorgibt und das seither in der Praxis umgesetzt wird. Basierend auf den theoretischen Grundlagen des St. Galler Management-Modells (SGMM) wird in dieser Arbeit untersucht, wie sich die Einführung eines Kinderschutzkonzepts auf die Organisationsentwicklung einer Kindertagesstätte auswirkt und welchen Einfluss das Kinderschutzkonzept auf die Qualität der Be- treuung und den Schutz der Kinder hat. Gemäss den Recherchen der Autorin existieren zwar einige Studien und Berichte über die Bedeutung eines Kinderschutzkonzepts, jedoch wurde dessen effektive Auswirkung in der Praxis bislang nicht empirisch erforscht. Die vorliegende Arbeit befasst sich somit als erste mit dieser Thematik. Es handelt sich um eine qualitative Studie. Die Daten dazu wurden mittels Interviews mit drei Gruppenleiterinnen erhoben und inhaltsanalytisch ausgewertet. Die Ergebnisse zeigen, dass ein in- dividuelles und im Betrieb gelebtes Kinderschutzkonzept einen grossen Einfluss auf die Personalführung, insbesondere auf die Entwicklung der Organisationskultur und auf den Wissensstand der Mitarbeitenden genommen hat. Auch in Bezug auf die Sicherheit der Kinder und der Mitarbeitenden konnte eine deutliche Entwicklung festgestellt werden. Am Ende der vorliegenden Masterarbeit werden aus den Erkenntnissen Konsequenzen für die Organisationsentwicklung und das Personalmanagement einer Kindertagesstätte aufgezeigt.

On Monte Carlo simulation algorithms for research in psychometrics
Creators: name: Olvera Astivia, Oscar Lorenzo
Publisher: name: University of British Columbia
Year: 2017

description: Monte Carlo simulations have become the workhorse of the modern methodologist aimed at providing both novel statistical insights and to guide data analysis practice. In spite of its widespread use, familiarity with data-generating algorithms is rare among users and consumers of simulation-based research, making the process appear as a “black box” of sorts. Without a good understanding of these algorithms, design flaws can appear in Monte Carlo studies which can influence the recommendations offered to applied researchers. In order to address these potential problems, this dissertation will highlight three issues in three separate papers related to the process of simulation as well as potential recommendations to deal with them. The first paper (chapter 2) focuses on the importance of matching the population model with the simulation design underlying the researcher’s hypothesis. It takes the Spearman rank correlation as a case study and documents the impact that potential disparities between simulation design and methodology can have on the conclusions derived from computer studies. The second paper (chapter 3) investigates a popular data-generating method within the social sciences, the Vale-Maurelli algorithm, and compares its results to a second one, the Headrick method, in terms of the kind of data they can generate and how this influences simulation results within a Structural Equation Modelling framework. The third paper (chapter 4) takes a closer look at the both the univariate (Fleishman) and multivariate (Vale-Maurelli) versions of the 3rd-order polynomial transformation to generate correlated, nonnormal data and documents the impact that its multiplicity of solutions has on simulation study results. In conclusion, this dissertation has the ultimate goal to help illuminate the process of simulation to psychometricians and social scientists alike in order to help create better study designs and promote a critical evaluation of Monte Carlo studies among methodologists and applied researchers alike.

description: Males of most amphibian species possess specialized cutaneous glands, known as sexually dimorphic skin glands (SDSGs). SDSGs are usually clustered in specific body regions and are externally visible, but in some cases, external differences between males and females can be slight or absent, and the occurrence of SDSGs can only be disclosed by histological studies. Chemical signals produced by SDSGs markedly affect amphibian behaviour and reproduction, and therefore their occurrence, features, and location in the body could provide information on potential mechanisms of intraspecific communication in a particular species. In the present study, we perform light microscope (both histological and histochemical), and scanning electron microscope studies of skin samples from male and female adult specimens of the invasive bullfrog Lithobates catesbeianus, covering several body regions that could hold SDSGs. Most skin areas analysed showed only ordinary granular and mucous glands despite remarkable sexual dimorphism that could be externally observed. By contrast, the male nuptial pads contained exclusively SDSGs that were hypertrophied specialized mucous glands (SMGs), closely resembling breeding glands described in other anurans. Our histochemical study revealed that these SMGs contain heterogeneous populations of secretory cells, possibly involved in pheromone production. We discuss these characteristics of the SDSGs found in L. catesbeianus, as well as the surface specialization of the nuptial pads (achieved by scanning electron microscopy) in the light of their potential role in the chemical communication in this invasive species.

description: Agent-based modeling and simulation is a useful method to study biological phenomena in a wide range of fields, from molecular biology to ecology. Since there is currently no agreed-upon standard way to specify such models it is not always easy to use published models. Also, since model descriptions are not usually given in mathematical terms, it is difficult to bring mathematical analysis tools to bear, so that models are typically studied through simulation. In order to address this issue, Grimm et al. proposed a protocol for model specification, the so-called ODD protocol, which provides a standard way to describe models. This paper proposes an addition to the ODD protocol which allows the description of an agent-based model as a dynamical system, which provides access to computational and theoretical tools for its analysis. The mathematical framework is that of algebraic models, that is, time-discrete dynamical systems with algebraic structure. It is shown by way of several examples how this mathematical specification can help with model analysis.

Recursive Inflationary Fractal Time (RIFT) Mathematical Foundations and Physical Implications
Creators: name: Del Bel, Julian
Publisher: name: Zenodo
Year: 2025

description: The Recursive Inflationary Fractal Time (RIFT) framework unifies number theory, fractal geometry, and quantum gravity through the handling of divergent infinite prime products and analytic continuation. Utilizing adelic integration, zeta function regularization, and recursive entropy dynamics, RIFT attains a theoretically stable cosmological constant Λ = 1 despite inherent divergences. Numerical validations up to 60 primes confirm convergence to Λ ≈ 1 ± 10−101, with precision scaling logarithmically with prime count. Observable predictions include fractal-modulated gravitational waves and Mersenne prime-induced dark matter hierarchies. 
description: The Recursive Inflationary Fractal Time (RIFT) framework addresses fundamental mathematical and physical challenges by reconciling divergent series with analytic regularization techniques. This approach unifies number theory, fractal geometry, and quantum gravity through a novel treatment of infinite prime products and their analytic continuation.

The formulation incorporates: 

• Adelic integration balancing real and p-adic number fields, establishing a duality principle that resolves the indeterminate ∞ · 0 expressions arising from divergent-vanishing product pairs.

• Zeta function regularization resolving infinite prime products through analytic continuation to s = 1 2 , where ζ(1/2) ≈ −1.4603545 provides a finite value for otherwise divergent Euler products.

• Recursive entropy dynamics with golden ratio (φ) scaling, ensuring physical consistency through self-similar information growth patterns that mirror inflationary cosmological expansion.

• Hyperspherical prime embedding in 4D spacetime, generating fractal lattices with angular separations scaled by φ = 1+√ 5 2 , establishing a geometric foundation for prime-modulated physical phenomena. These elements collectively impose stability on the cosmological constant (Λ = 1 ± 10−101 for 60 primes) and predict novel fractal structures in cosmology, including φ-modulated gravitational wave echoes and Mersenne prime-derived dark matter hierarchies. Numerical validations demonstrate precision scaling logarithmically with prime count ( ∼ exp(−cN/ ln N)), achieving "14.07 orders" of refinement beyond initial calculations.

description: We describe a class of time-dependent solutions in string- or M-theory that are exact with respect to alpha-prime and curvature corrections and interpolate in physical space between regions in which the low energy physics is well-approximated by different string theories and string compactifications. The regions are connected by expanding "domain walls" but are not separated by causal horizons, and physical excitations can propagate between them. As specific examples we construct solutions that interpolate between oriented and unoriented string theories, and also between type II and heterotic theories. Our solutions can be weakly curved and under perturbative control everywhere and can asymptote to supersymmetric at late times.

Using this theory, we construct numerous new rotating black holes with charges and dipoles of D-branes, fundamental strings and other branes. In some instances, the black holes can be dynamically stable close enough to extremality. Some of these black holes, such as those based on the D1-D5-P system, have extremal, non-supersymmetric limits with regular horizons of finite area and a wide variety of horizon topologies and geometries.

description: We report detections of three z ~ 2.5 submillimeter-selected galaxies (SMGs; SMM J14011+0252, SMM J14009+0252, SMM J04431+0210) in the lowest rotational transition of the carbon monoxide molecule (CO J = 1-0) and one nondetection (SMM J04433+0210). For the three galaxies we detected, we find a line-integrated brightness temperature ratio of the J = 3-2 and 1-0 lines of 0.68 +/- 0.08; the 1-0 line is stronger than predicted by the frequent assumption of equal brightnesses in the two lines and by most single-component models. The observed ratio suggests that mass estimates for SMGs based on J = 3-2 observations and J = 1-0 column density or mass conversion factors are low by a factor of 1.5. Comparison of the 1-0 line intensities with intensities of higher-J transitions indicates that single-component models for the interstellar media in SMGs are incomplete. The small dispersion in the ratio, along with published detections of CO lines with J_upper > 3 in most of the sources, indicates that the emission is from multi-component interstellar media with physical structures common to many classes of galaxies. This result tends to rule out the lowest scaling factors between CO luminosity and molecular gas mass, and further increases molecular mass estimates calibrated against observations of galaxies in the local universe. We also describe and demonstrate a statistically sound method for finding weak lines in broadband spectra that will find application in searches for molecular lines from sources at unknown redshifts.
description: 14 pages, 7 figures, accepted for publication in Ap.J. Final version includes some structural and referencing changes suggested by the referee. Independently, CO 1-0 line fluxes have increased by ~20% from original astro-ph submission to correct a numerical error found after submission; this change is small and does not alter original overall discussion or conclusions
Origin of In-Plane Anisotropy in Optical Conductivity for Antiferromagnetic Metallic Phase of Iron Pnictides

description: We examine the optical conductivity in antiferromagnetic (AFM) iron pnictides by mean-field calculation in a five-band Hubbard model. The calculated spectra are well consistent with the in-plane anisotropy observed in the measurements, where the optical conductivity along the direction with the AFM alignment of neighboring spins is larger than that along the ferromagnetic (FM) direction in the low-energy region; however, that along the FM direction becomes larger in the higher-energy region. The difference between the two directions is explained by taking account of orbital characters in both occupied and unoccupied states as well as of the nature of Dirac-type linear dispersions near the Fermi level.

Foraging ecology of Endangered Williamson’s Sapsuckers in Canada : multi-scale habitat selection in two biogeoclimatic zones
Creators: name: St-Amand, Julien
Publisher: name: University of British Columbia
Year: 2017

description: Williamson’s Sapsuckers are Endangered woodpeckers in Canada that breed in montane forests only in British Columbia and require protection of their critical habitat. While there is reasonable knowledge of their distribution and nesting habitat requirements, there are knowledge gaps regarding foraging habitat of Williamson’s Sapsuckers. I investigated the selection of foraging habitat in managed forest at the foraging substrate and patch scales using visual observations of foraging behaviour of 27 radio-tagged Williamson’s Sapsuckers in the two biogeoclimatic zones where they are found in Canada, the Montane Spruce and Interior Douglas-fir. The characteristics of foraging trees differed with foraging mode and nesting status, but not with bird gender or age. Williamson’s Sapsuckers preferred large live Douglas-fir (> 22.5 cm dbh) for gleaning and sap feeding in both biogeoclimatic zones, while trees used for pecking were mostly large dying western larch in the Montane Spruce zone and large dead ponderosa pine in the Interior Douglas-fir zone. At the foraging patch scale, Williamson’s Sapsuckers did not prefer any stand-level characteristics in the Montane Spruce zone, while in the Interior Douglas-fir zone, they selected foraging patches with higher densities of their preferred foraging substrate (i.e., large live Douglas-fir). Areas of open habitat and single trees were avoided during foraging trips in both biogeoclimatic zones and this habitat type was found in significantly lower proportions in the Montane Spruce than in the Interior Douglas-fir zone. Williamson’s Sapsuckers showed no significant preferences for within-stand configuration characteristics (retained groups, forest edges, open stands and closed stands) in the Montane Spruce zone, but they preferred foraging along forest edges and in closed stands in the Interior Douglas-fir zone. I used foraging trip distances to recommend nest reserve (no-logging; 0-140 m from the nest) and nest management zones. For the nest management zone, I recommend only partial harvesting with retained groups of trees extending from 140-340 m in the Montane Spruce zone and from 140-410 m in the Interior Douglas-fir zone. My study on Williamson’s Sapsuckers is the first to provide a comprehensive representation of foraging habitat requirements for the species.

We argue that the new work is based on models that do not capture the relevant physics, and that almost all models of observable high energy Lorentz violation, and proposed Lorentz-violating theories of quantum gravity, are ruled out by low energy tests; the only known exceptions are based on supersymmetry.

description: Die Art und Weise wie Freiwillige geführt werden, trägt viel dazu bei, ob sich Freiwillige in einer Organisation wohl fühlen und ihr Engagement längerfristig ausüben. Diese Arbeit geht den Fragestellungen nach, inwiefern sich Führung von Freiwilligenarbeit unterscheidet im Vergleich zur Führung von bezahlten Mitarbeitenden. Die Fragestellung wird noch weiter vertieft, inwiefern Führung für Freiwillige im Alltag gestaltet werden kann, damit Freiwillige ihr Engagement konstruktiv und nachhaltig gegenüber der Organisation ausüben. Anhand von Literaturrecherchen, Auswertungen von Studien und Fachgesprächen wird das Thema aus verschiedenen Blickwinkeln beleuchtet. Die Theorie wird dabei immer wieder mit Inputs aus der Praxis ergänzt und eigene Erlebnisse reflektiert. Zur Untersuchung der Freiwilligenarbeit und deren Umgang damit im Führungsalltag werden verschiedene theoretische Modelle gebraucht: die Selbstbestimmungstheorie, der funktionale Ansatz zur Beleuchtung der Motive für Freiwilligenarbeit und die Rollenidentitätstheorie. Im letzen Teil der Arbeit wurde die Führung von Freiwilligen auf Situationen im Führungsalltag bezogen und entsprechende Empfehlungen formuliert. Es zeigt sich, dass Freiwillige viel Freiheit und Selbstbestimmung bei der Ausübung ihrer Tätigkeiten brauchen, damit sie diese als erfüllend erleben. Bei der Führung von Freiwilligen spielen Werte eine grosse Rolle, die Tätigkeit muss als sinnvoll erlebt werden können und mit den eigenen Wertvorstellungen übereinstimmen. Die Führungsperson kann diesen Prozess begleiten und unterstützen. Ansonsten darf die Führungsperson nicht zu stark regulativ eingreifen bei der Führung von Freiwilligen, da dies deren Motivation negativ beeinflussen kann. Freiwilligenarbeit befindet sich im Wandel. Die Freiwilligen von heute haben andere Ansprüche und Erwartungen wie früher. Dem müssen Organisationen und Führungspersonen Rechnung tragen und sich an die neuen Gegebenheiten anpassen. Auch wenn es schwieriger geworten ist, Freiwillige zu finden, können Organisationen mit passenden Aufgabenprofilen, Gestaltungsspielraum für die Freiwilligen und wertorientierten Tätigkeiten die Basis für ein nachhaltiges und für beide Seiten bereicherndes Engagement schaffen.

description: We consider a uniformly accelerated atom interacting with a vacuum electromagnetic field in the presence of an infinite conducting plane boundary and calculate separately the contributions of vacuum fluctuations and radiation reaction to the atomic energy level shift. We analyze in detail the behavior of the total energy shift in three different regimes of the distance in both the low acceleration and high acceleration limits. Our results show that, in general, an accelerated atom does not behave as if immersed in a thermal bath at the Unruh temperature in terms of the atomic energy level shifts, and the effect of the acceleration on the atomic energy level shifts may in principle become appreciable in certain circumstances, although it may not be realistic for actual experimental measurements. We also examine the effects of the acceleration on the level shifts when the acceleration is of the order of the transition frequency of the atom and we find some features differ from what was obtained in the existing literature.

description: We present studies of W and Z bosons with associated high energy photons produced in pp collisions at sqrt(s)=7 TeV. The analysis uses 35 pb-1 of data collected by the ATLAS experiment in 2010. The event selection requires W and Z bosons decaying into high pT leptons (electrons or muons) and a photon with ET>15 GeV separated from the lepton(s) by a distance Delta_R(l,gamma)>0.7 in eta-phi space. A total of 95 (97) pp->e nu gamma + X (pp->mu nu gamma + X) and 25 (23) pp->e+ e- gamma + X (pp->mu+ mu- gamma + X) event candidates are selected. The kinematic distributions of the leptons and photons and the production cross sections are measured. The data are found to agree with Standard Model predictions that include next-to-leading-order O(alpha alpha_s) contributions.

Characterization of IAPLTR1 subclasses and bidirectional promoter activity : "making sense of it all"
Creators: name: Little, Natasha W.
Publisher: name: University of British Columbia
Year: 2017

description: Endogenous retroviruses (ERVs) are over five-times more prevalent than gene coding sequences in the mouse and human genomes (5). The long terminal repeats (LTRs) of these elements are promoter-enhancers that can have many regulatory effects on the host genome (3). Intracisternal A-Particles (IAPs) are a highly active, murine-specific class of ERV that is known to have strong LTR-driven promoter activity (10). In a recent study, a sequence divergence-based subclass nomenclature was suggested for several classes of IAPLTR – including IAPLTR1 (59). However, it remained unknown whether these high (H1) and low (L1) divergence subclasses provided any more biologically relevant information than the current class system (with no subclasses). Some, but not all, IAPLTRs can initiate sense and antisense transcripts and have thus been considered bidirectional promoters; however, due to growing interest in their form and function, a set of criteria has recently been established for what defines a bidirectional promoter and bidirectional reporter constructs have been developed. The research presented in this thesis provides a detailed analysis of bidirectional and unidirectional reporter constructs and provides evidence that bidirectional reporter constructs should be used when assaying bidirectional promoters. Using a bidirectional reporter construct, IAPLTR1 was determined to meet the criteria for a bidirectional promoter. The core promoters for IAPLTR1 and putative transcription factor binding sites that were unique to each subclass were identified. Point mutagenesis experiments revealed that functional divergence accompanied the sequence divergence of H1 and L1 subclasses. In fact, 95% of the total promoter activity of an L1 LTR was removed by changing three base-pairs to resemble the same region of an H1 LTR. The reciprocal experiment resulted in the H1 LTR losing 100% of antisense promoter activity, but maintaining 100% of sense promoter activity. These experiments, among others, provide evidence that the subclass system provides more biologically relevant information than the single IAPLTR1 class, and therefore should be adopted as part of IAP nomenclature.

description: Das Ziel dieser Forschungsarbeit ist es, KMU einen Überblick über die möglichen Instrumente für die Erfolgskontrolle von Social Media Marketing zu geben. Dabei wird sich auf die folgende Forschungsfrage konzentriert: „Welche Instrumente existieren, um Social Media Maßnahmen auf ihren Erfolg zu prüfen?“. Zur Beantwortung der Forschungsfrage wurde zunächst eine Literaturrecherche durchgeführt, bei der gezielt nach Modellen und Kennzahlen gesucht wurde. In diesem Zusammenhang fand eine empirische Analyse von Social Media Tools statt. Außerdem wurde eine Online-Umfrage konzipiert und an KMU versendet, um zu erfahren, wie die KMU aktuell den Erfolg messen. Dabei zeigte die Literaturrecherche, dass bis heute kein einheitlicher Ansatz für die Erfolgskontrolle existiert und die Social Media Tools verschiedene Kennzahlen bereitstellen. Darüber hinaus hat die Online-Umfrage ergeben, dass viele der Teilnehmer ihre Erfolgskontrolle sehr einfach handhaben, wofür vor allem fehlende Ressourcen verantwortlich sind.
description: The aim of this research work is to give SMEs an overview of the possible instruments for monitoring the success of social media marketing. The focus is on the following research question: "Which instruments exist to check social media measures for their success?" To answer the research question, a literature search was first carried out, in which a targeted search was made for models and key figures. In this context, an empirical analysis of social media tools took place. In addition, an online survey was designed and sent to SMEs to find out how SMEs are currently measuring success. The literature research showed that there is still no uniform approach to monitoring success and that the social media tools provide various key figures. In addition, the online survey showed that many of the participants manage their success control very easily, which is mainly due to a lack of resources.

description: We use two-laser optical pumping on a continuous atomic fountain in order to prepare cold cesium atoms in the same quantum ground state. A first laser excites the F=4 ground state to pump the atoms toward F=3 while a second pi-polarized laser excites the F=3 -> F'=3 transition of the D2 line to produce Zeeman pumping toward m=0. To avoid trap states, we implement the first laser in a 2D optical lattice geometry, thereby creating polarization gradients. This configuration has the advantage of simultaneously producing Sisyphus cooling when the optical lattice laser is tuned between the F=4 -> F'=4 and F=4 -> F'=5 transitions of the D2 line, which is important to remove the heat produced by optical pumping. Detuning the frequency of the second pi-polarized laser reveals the action of a new mechanism improving both laser cooling and state preparation efficiency. A physical interpretation of this mechanism is discussed.

Hydrodynamics with conserved current via AdS/CFT correspondence in the Maxwell-Gauss-Bonnet gravity

description: Using the AdS/CFT correspondence, we study the hydrodynamics with conserved current from the dual Maxwell-Gauss-Bonnet gravity. After constructing the perturbative solution to the first order based on the boosted black brane solution in the bulk Maxwell-Gauss-Bonnet gravity, we extract the stress tensor and conserved current of the dual conformal fluid on its boundary, and also find the effect of Gauss-Bonnet term on the dual conformal fluid. Our results show that the Gauss-Bonnet term can affect the parameters such as the shear viscosity $η$, entropy density $s$, thermal conductivity $κ$ and electrical conductivity $σ$. However, it does not affect the so-called Wiedemann-Franz law which relates $κ$ to $σ$, while it affects the ratio $η/s$. In addition, another interesting result is that the $η/s$ can also be affected by the bulk Maxwell field in our case, which is consistent with some previous results predicted through the Kubo formula. Moreover, the anomalous magnetic and vortical effects by adding the Chern-Simons term are also considered in our case in the Maxwell-Gauss-Bonnet gravity.

description: By converting the rectangular basis potential V(x,y) into the form as V(r)+V(r, phi) described by the pseudo central plus noncentral potential, particular solutions of the two dimensional Schrodinger equation in plane-polar coordinates have been carried out through the analytic approaching technique of the Nikiforov and Uvarov (NUT). Both the exact bound state energy spectra and the corresponding bound state wavefunctions of the complete system are determined explicitly and in closed forms. Our presented results are identical to those of the previous works and they may also be useful for investigation and analysis of structural characteristics in a variety of quantum systems

description: In my senior project called “Garden From the Concrete”, I explore how Asian college-aged women survivors’ process of healing from sexual assault while being situated in a red-state through a collaborative photo book. In preparation of the collaborative photo book, I reached out to Asian college-aged women sexual assault survivors in my home-state, which is Oklahoma. I gave the participants the prompt of “Describe your process of healing from sexual assault in a conservative community as an Asian college-aged woman in six pictures.” As photography can provide barriers to entry as it is an expensive hobby, I allowed my collaborators to include any pictures that were financially sustainable for them. As a result of four collaborators (including myself), I gathered film photos and digital photos (from both phone photography and professional camera photography).
Efficient Algorithm for Asymptotics-Based Configuration-Interaction Methods and Electronic Structure of Transition Metal Atoms

description: Asymptotics-based configuration-interaction (CI) methods [G. Friesecke and B. D. Goddard, Multiscale Model. Simul. 7, 1876 (2009)] are a class of CI methods for atoms which reproduce, at fixed finite subspace dimension, the exact Schrödinger eigenstates in the limit of fixed electron number and large nuclear charge. Here we develop, implement, and apply to 3d transition metal atoms an efficient and accurate algorithm for asymptotics-based CI. Efficiency gains come from exact (symbolic) decomposition of the CI space into irreducible symmetry subspaces at essentially linear computational cost in the number of radial subshells with fixed angular momentum, use of reduced density matrices in order to avoid having to store wavefunctions, and use of Slater-type orbitals (STO's). The required Coulomb integrals for STO's are evaluated in closed form, with the help of Hankel matrices, Fourier analysis, and residue calculus. Applications to 3d transition metal atoms are in good agreement with experimental data. In particular we reproduce the anomalous magnetic moment and orbital filling of Chromium in the otherwise regular series Ca, Sc, Ti, V, Cr.

description: A search for diphoton events with large missing transverse energy is presented. The data were collected with the ATLAS detector in proton-proton collisions at sqrt(s) = 7 TeV at the CERN Large Hadron Collider and correspond to an integrated luminosity of 3.1/pb. No excess of such events is observed above the Standard Model background prediction. In the context of a specific model with one Universal Extra Dimension with compactification radius R and gravity-induced decays, values of 1/R < 728 GeV are excluded at 95% CL, providing the most sensitive limit on this model to date.

description: Detecting the dark matter annihilation signal from Galactic substructure, or subhalos, is an important challenge for high-energy gamma-ray experiments. In this paper we discuss detection prospects by combining two different aspects of the gamma-ray signal: the angular distribution and the photon counts probability distribution function (PDF). The true PDF from subhalos has been shown recently (by Lee et al.) to deviate from Poisson; we extend this analysis and derive the signal PDF from a detailed Lambda-CDM-based model for the properties of subhalos. We combine our PDF with a model for Galactic and extra-Galactic diffuse gamma-ray emission to obtain an estimator and projected error on dark matter particle properties (mass and annihilation cross section) using the Fermi Gamma-Ray Space Telescope. We compare the estimator obtained from the true PDF to that obtained from the simpler Poisson analysis. We find that, although both estimators are unbaised in the presence of backgrounds, the error on dark matter properties derived from the true PDF is ~50% smaller than when utilizing the Poisson-based analysis.
