description:
HIV-1 infection greatly alters the NK cell phenotypic and functional repertoire. This is highlighted by the expansion of a rare population of FcRγ- NK cells exhibiting characteristics of traditional immunologic memory in people with HIV (PWH). Although current antiretroviral therapy (ART) effectively controls HIV-1 viremia and disease progression, its impact on HIV-1-associated NK cell abnormalities remains unclear. To address this, we performed a longitudinal analysis detailing conventional and memory-like NK cell characteristics in n = 60 PWH during the first 4 y of ART. Throughout this regimen, a skewed repertoire of cytokine unresponsive FcRγ- memory-like NK cells persisted and accompanied an overall increase in NK surface expression of CD57 and KLRG1, suggestive of progression toward immune senescence. These traits were linked to elevated serum inflammatory biomarkers and increasing Ab titers to human CMV, with human CMV viremia detected in approximately one-third of PWH at years 1-4 of ART. Interestingly, 40% of PWH displayed atypical NK cell subsets, representing intermediate stages of NK-poiesis based on single-cell multiomic trajectory analysis. Our findings indicate that NK cell irregularities persist in PWH despite long-term ART, underscoring the need to better understand the causative mechanisms that prevent full restoration of immune health in PWH.
Post Stroke Lingual Dystonia: Clinical Description and Neuroimaging Findings

description: Background: Lingual dystonia is extremely rare following stroke. We describe clinical features and neuroimaging findings in a series of 11 patients (seven acute and four chronic) with post-stroke lingual dystonia and review the literature.

Methods: This was a case series using a preformed structured proforma and review of literature using a PubMed search.

Results: In our case series, all patients had dysarthria as a presenting symptom. Seven patients had acute presentation (six had an ischemic infarct and one had thalamic hemorrhage) and four had chronic presentation (all had infarct). All patients except one had small infarcts, with the majority of them in the basal ganglia and subcortical white matter regions. Additional chronic ischemic lesions were seen in all patients with acute presentation. The majority of the patients with acute (five out of seven; 71.42%) presentation had left-sided involvement on imaging. We could identify only one case of acute post-stroke lingual dystonia following the PubMed search. Three other cases of post-stroke lingual dystonia with chronic presentation have been described; however, these were associated with oromandibular or cranial dystonia.

Discussion: Our results, based on brain lesions, suggest that all lingual dystonia patients with acute infarcts had underlying chronic infarcts. Overall, more left-sided than right-sided strokes were observed with post-stroke lingual movement disorders including dystonia; however, the data were not significant (p = 1). All patients had dysarthria, with only one having mild tongue weakness and only four having facial weakness. This suggests that the lingual dystonia was responsible for the dysarthria rather than weakness in these patients.

description: We have performed the first measurement of the angular power spectrum in the large-scale diffuse emission at energies from 1-50 GeV. We compared results from data and a simulated model in order to identify significant differences in anisotropy properties. We found angular power above the photon noise level in the data at multipoles greater than ~ 100 for energies 1< E <10 GeV. The excess power in the data suggests a contribution from a point source population not present in the model.

description: Overhead athletes are required to throw or perform movement at high velocities to achieve success in their particular sport. Biomechanical abnormalities will develop from repetitive throwing motions and from generating increased amounts of force through speed and power changes in your sport. It is crucial to work on shoulder complex range of motion, stability, and neuromuscular control to perform and train in optimal position and in turn generate the most force during overhead movement.
Where's The Justice? A Review of the Local Food Movement Through a Reflexive Lens
Creators: name: Kilmer, Colyn
Publisher: name: Utah State University
Year: 2012

description: As the local food movement has gained momentum over the past several years, so too has it garnered critiques from academic scholars. This literature review identified academic critiques of the local food movement. These critiques were organized into four general categories. A fifth category, reflexivity, was identified, which functioned as both a critique and a way to address the other four categories of critique. This review paired the four categories of academic critique with ways in which several academic scholars suggested reflexivity could be used to resolve these critiques. This review was designed to give scholars, practitioners, and consumers associated with local food projects a broad overview of academic critiques of the local food movement and the ways in which reflexivity has been suggested as a means to address these critiques.
Is Analyst Over Optimism Creating Price Inefficiency in the Stock Market?
Creators: name: Guiliani, Juan Mauricio
Publisher: name: Utah State University
Year: 2012

description: This study aims to uncover the relationship between market frictions, measured by price delay, and consensus analyst recommendations on stocks. Analyst recommendations are publicly available to investors, and under the framework of the Efficient Market Hypothesis, should contribute to the efficiency of a stock’s pricing mechanism by providing information to the market that would otherwise not be available. We find evidence that the more favorable recommended stocks in our sample command a higher price delay than less favorably recommended stocks. In other words, the most optimistically recommended stocks are priced less efficiently than other less favorably recommended stocks. We also find evidence that consensus analyst recommendations affect price delay only for stocks recommended better than “hold”. Stocks with consensus recommendations worse than “hold” do not show a significant relationship between consensus analyst recommendations and price delay. The results are robust to other factors that have been shown to affect delay.
Scaffolding Improvement in Writing Instruction: An Action Research Project
Creators: name: Miller, Kristine W.
Publisher: name: Utah State University
Year: 2012

description: Research has demonstrated students may improve their writing ability when cognitive strategies are demonstrated for them in clear and explicit ways as they observe and participate in writing events directed by knowledgeable writers, particularly when these events are followed by opportunities for independent writing. Carefully crafted scaffolding with abundant amounts of oral interaction such as that in Read’s IMSCI model that includes inquiry, modeling, shared writing, collaboration and independent writing, can give students the needed support to develop skills essential to quality writing. An informational genre unit was developed with seven specific lesson plans focusing on the five elements in this model. Data were then collected that indicated student growth in use of specific genre features following explicit, strategic, and scaffolded writing instruction. Read-alouds appeared to be essential for providing explicit examples of genre features and helped teachers to demonstrate both product and writing process. Use of these daily instruction plans gave a focus on specific objectives for each lesson and added spiraling of new information to help students apply learning to their own writing. Also demonstrated in the data was an increase in desired student behavior during writing time with scaffolded instruction. Success of this research indicated that explicit scaffolding in any instructional area will improve student learning.

“Next Year in Jerusalem”: The Trials and Triumphs of Music in the Schools of Preston, Idaho, 1888-1995
Creators: name: Durrant, Jill
Publisher: name: Utah State University
Year: 2012

description: Throughout time, music has played a pivotal role in the lives of people. In every country, among every ethnicity, and as part of every culture, music has a presence. Music often acts as a mirror, reflecting aspects of society and history in ways that even the ordinary person can understand. No matter what the form—religious, popular, classical, folk—music has the ability to reveal something about the people who created it, performed it, and enjoyed it. Because of this overarching presence of music in the structure of almost every civilization, it is no surprise that music has always had some part in the way those societies choose to educate their children. Music has long been included in the public schools of the United States, but that history in education is a rocky one—as evidenced by the story above—fluctuating up and down according to the whims of administration, economic situations, educational policies and reforms, and the desires of communities. Music has been continually under pressure to prove its value as an educational subject and hold its own against other subjects and activities despite centuries of evidence in its favor. A study of the music offered in the schools of Preston, Idaho provides an example of how one rural community dealt with these issues, a micro-capture of what was happening in the nation at large with regards to music education. However, because of Preston’s unique location and cultural history, it also offers an opportunity to observe how an individual school’s decisions toward music in the curriculum are effected by the community that produces it, sometimes creating marked contrast to national trends.
Streambed Thermal Property Instrument (SPI)
Creators: name: Dayie, James Alwel
Publisher: name: Utah State University
Year: 2012

description: The purpose of this research, the Streambed thermal Property Instrument (SPI) is to determine the applicability of this instrument for in situ thermal (conductivity and diffusivity) and porous flow (magnitude and direction) measurements. Currently, no such thermal instrument exists for such in situ measurements and the reason for developing this unique instrument, the SPI to fill the technology gap in sediment thermal property measurement devices. Prior to testing the instrument under controlled laboratory conditions to determine its functionality through a series of static and flow tests, the instrument was designed and built. A lab-sized version of an actual river called a flow cell with a gravity-driven flow was also built, making it possible for testing the SPI under controlled lab conditions .The instrument was tested in the flow case by fixing the instrument in two orientations in the saturated porous media (glass particles). Results from the static tests indicated that these bulk thermal measurements (diffusivity and conductivity) can be off the expected value by as much as 15% while the porous flow measurements (magnitude and direction) displayed more variability in results for the two orientations of the probe for the flow rate range considered. This variability in flow measurements has been partly attributed to the movement of the offset probes during insertion and rotation and the large size of the center probe of the SPI. The findings from this research has made it possible for more advanced research in this field by using computer simulations to make possible, accurate porous flow measurements using a large scale thermal probe such as the SPI.

The determinant invariants can be constructed by a simple method and the set of all these determinant invariants is complete with respect to permutations of qubits. SLOCC entanglement classification can be achieved via the vanishing or not of the determinant invariants. We exemplify the method for several even number of qubits, with an emphasis on six qubits.

Multi-National River Basin Cooperation and Management Case Study: Senegal River Basin
Creators: name: Ayaa, Patricia
Publisher: name: Utah State University
Year: 2012

description: With increasing populations, urbanization and thus increasing demand for water, conflict on International River basins has been increasing over the years which has necessitated formation of International River frameworks to devise means of cooperation among the countries sharing the river basins. The main modes of cooperation in international river basins include allocating the waters of the river to the sharing countries such that each country manages its own water resources, or treating the river basin as one system and jointly managing and sharing the costs and benefits from the various services or use-sectors of the river.
This research was aimed at reviewing and comparing international frameworks managing some of the rivers in Africa and Asia, and their structures, history and accomplishments. The countries sharing the Senegal River are Mali, Mauritania, Senegal and Guinea. The Senegal River was used as a case study because of the success of the OMVS, which is the organization managing the river basin. The OMVS has managed the river since 1972 and has succeeded in resolving water-related conflicts in the basin. The Senegal River basin countries are cooperating through joint management of the services and use-sectors fed by the river and thus sharing costs and benefits accumulated from use of the river. The benefits and costs from the project are calculated and then allocated through allocation models that were developed by the OMVS. The results in this research obtained from the Cost Allocation Model (as of 2011) which uses the Adjusted Separable Cost Remaining Benefit (ASCRB) method to allocate costs to the countries involved indicate that of the total project costs, Mali should pay 43.9%, Senegal should pay 38.94% and Mauritania should pay 17.16%. The ASCRB method was used because it satisfies the principles of benefit-cost sharing which include equity and economic efficiency. Countries sharing International River basins should therefore emulate the Senegal River basin countries on ways to resolve water conflicts with working methods such as the ASCRB method.

description: We study the quantum field theory (QFT) of a free, real, massless and curvature coupled scalar field on self-similar symmetric spacetimes, which are deformed by an abelian Drinfel'd twist constructed from a Killing and a homothetic Killing vector field. In contrast to deformations solely by Killing vector fields, such as the Moyal-Weyl Minkowski spacetime, the equation of motion and Green's operators are deformed. We show that there is a *-algebra isomorphism between the QFT on the deformed and the formal power series extension of the QFT on the undeformed spacetime. We study the convergent implementation of our deformations for toy-models. For these models it is found that there is a *-isomorphism between the deformed Weyl algebra and a reduced undeformed Weyl algebra, where certain strongly localized observables are excluded. Thus, our models realize the intuitive physical picture that noncommutative geometry prevents arbitrary localization in spacetime.

Moreover, we show that the Demazure modules appearing in these two objects coincide exactly. Though these results have been previously known in the simply laced case, they are new in the non-simply laced case.

description: Background: Drug-induced tremors after long-term administration of anti-epileptics have been described in the literature. Such tremors are usually postural or action in nature with infrequent resting nature.

Case Report: A 23-year-old female presented in status epilepticus. Past and family histories were negative for seizures. She was managed per protocol with valproate. Within hours, she developed resting tremors. The tremors subsided on changing the anti-epileptic.

Discussion: Resting tremors have mostly been described in the literature as long-term side-effects of valproate. This case illustrates that even short-term infusion of valproate can cause resting tremors.

description: Track and field, formally know as athletics, formed part of the first Olympics in 776 BC and was included in the first modern Olympic Games in 1896 (Quercetany, 2000). Ever since the creation of this sport, sport related injury has followed. The inevitability of musculoskeletal injury associated with sports in general is well known amongst its participants, and the people who research it. According to the NCAA Injury Surveillance System, a sixteen year sampling period (1988 through 2004), recorded 182,000 injuries (Hootman, Dick, & Agel, 2007). Despite the risk for injury, people continue to participate in track and field. During that 16 year sampling period, participation has increased among both sexes: (80% increase in females and 20% increase in males) in all NCAA championship sports (Hootman, Dick, & Agel, 2007).

description: In this review we first outline the basics of transport theory and its recent generalization to off-shell transport. We then present in some detail the main ingredients of any transport method using in particular the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) implementation of this theory as an example. We discuss the potentials used, the ground state initialization and the collision term, including the in-medium modifications of the latter. The central part of this review covers applications of GiBUU to a wide class of reactions, starting from pion-induced reactions over proton and antiproton reactions on nuclei to heavy-ion collisions (up to about 30 AGeV). A major part concerns also the description of photon-, electron- and neutrino-induced reactions (in the energy range from a few 100 MeV to a few 100 GeV). For this wide class of reactions GiBUU gives an excellent description with the same physics input and the same code being used. We argue that GiBUU is an indispensable tool for any investigation of nuclear reactions in which final-state interactions play a role. Studies of pion-nucleus interactions, nuclear fragmentation, heavy ion reactions, hyper nucleus formation, hadronization, color transparency, electron-nucleus collisions and neutrino-nucleus interactions are all possible applications of GiBUU and are discussed in this article.

description: Background: To evaluate the surgical technique using autologous retinal graft (ARG) and autologous blood clot (ABC) for the management of refractory macular holes (MHs).

Methods: This study was a retrospective, consecutive, interventional case series. Six eyes of 6 patients who underwent vitrectomy combined with ARG and ABC for the treatment of refractory MH were reviewed. Visual and anatomic outcomes were evaluated.

Results: The mean age was 59.0 ± 9.9 years. All cases had multiple vitreoretinal procedures including vitrectomy and gas fluid exchange before patient presentation. The average numbers of vitrectomies were 2.3 ± 0.5, and those of gas fluid exchange were 3 ± 1.7. Closure of the macular hole was achieved in four (66.7%) cases at last follow-up. The mean follow-up time was 25.2 ± 15.6 months. The averaged BCVA before and after 12 months of the surgery improved from 20/591 to 20/244.

Conclusions: This surgical technique using ARG and ABC provide an option for the treatment of refractory MHs.

description: Suppose a finite group acts on a scheme X and a finite-dimensional Lie algebra g. The associated equivariant map algebra is the Lie algebra of equivariant regular maps from X to g. Examples include generalized current algebras and (twisted) multiloop algebras. Local Weyl modules play an important role in the theory of finite-dimensional representations of loop algebras and quantum affine algebras. In the current paper, we extend the definition of local Weyl modules (previously defined only for generalized current algebras and twisted loop algebras) to the setting of equivariant map algebras where g is semisimple, X is affine of finite type, and the group is abelian and acts freely on X. We do so by defining twisting and untwisting functors, which are isomorphisms between certain categories of representations of equivariant map algebras and their untwisted analogues. We also show that other properties of local Weyl modules (e.g. their characterization by homological properties and a tensor product property) extend to the more general setting considered in the current paper.

The Language Teaching Puzzle
Creators: name: Child, Gregory S.
Publisher: name: Utah State University
Year: 2012

description: This portfolio is a compilation of beliefs about effective foreign language (FL) teaching. The core of this portfolio is a teaching philosophy, in which theories, such as comprehensible input, teacher and student roles, and activities are explained. The teaching philosophy is accompanied by a reflection of the authors teaching observed from a video. Following the teaching philosophy and personal teaching reflection are three artifacts centered on language, culture, and literacy. The language artifact contains an observational study in which instructors’ practices are compared with their beliefs. The cultural artifact is focused on storytelling. Many civilizations employ storytelling in the form of oral traditions to pass on learning. In the artifact, effectiveness of storytelling as an approach to FL teaching and learning is examined. The literacy artifact is a proposal for a research study. In the proposal, questions are raised about the effectiveness of computer-aided support materials offered to students as they navigate various texts. The final sections of the portfolio contain a “looking forward” section, an annotated bibliography, and references.
In Situ Method of Measuring Atmosphere Neutral Winds with a Rigid Falling Sphere

Publisher: name: Utah State University
Year: 2012

description: The new falling sphere instruments will measure lower E-region winds and density, which are critical for many of the electrodynamics and plasma physics studies that are carried out as part of the NASA suborbital rocket program. The new falling sphere design will take advantage of modern commercially available electronic components and materials. Of primary importance, it is proposed to fly an in-situ instrument that targets the measurement of neutral wind profiles over the altitude range from 80 to 150 km, with accuracy better than that achieved in previous implementations of the falling sphere technique and those typically obtained with the chemical release technique. The falling sphere instrument will measure the lower E-region winds and density, which are critical for many of the electrodynamics and plasma physics studies that are carried out as part of the NASA Geospace suborbital rocket program. This gives a report of the overall design and the rigid body dynamics involved as well as some post flight analysis.
The SHO Goes On: A Theoretical and Empirical Evaluation of Uptick-Related Short-Sale Constraints
Creators: name: Bylund, Alexander James
Publisher: name: Utah State University
Year: 2012

description: This paper explores the effects of uptick-related short-sale constraints first on the Glosten-Milgrom Model of Sequential Trade and then empirically on the stocks in the Russell 3000 index used by the SEC in the pilot program created by Reuglation SHO. Finally, the effect of uptick constraints on the relationship between the short and put call ratios is studied through the use of impulse response functions. Both the general and alternative uptick rules are found to decrease informational efficiency in hypothetical financial markets, have no statistically significant positive effects on key financial market metrics, and the change in sign from negative to positive in the response of the put call ratio to a positive shock in the short ratio may be seen as evidence of the use of the options market to avoid short-sale constraints.

description: Lattice models are abundant in theoretical and condensed-matter physics. Generally, lattice models contain time-independent hopping and interaction parameters that are derived from the Wannier functions of the noninteracting problem. Here, we present a new concept based on time-dependent Wannier functions and the variational principle that leads to optimal time-dependent lattice models. As an application, we use the Bose-Hubbard model with time-dependent Wannier functions to study a quench scenario involving higher bands. We find a separation of times scales in the dynamics and show that under some circumstances the multi-band nonequilibrium dynamics of a quantum system can be obtained essentially at the cost of a single-band model.

description: The bubble wall velocity in an electroweak first order phase transition is a key quantity both for electroweak baryogenesis and for the production of a stochastic background of gravitational waves that may be probed in the future through gravitational wave experiments like LISA or BBO. We show that, contrary to the conclusion drawn from previous studies, it is actually possible to generate a potentially large gravitational wave signal while satisfying the requirements for viable electroweak baryogenesis, once the effects of the hydrodynamics of bubble growth are taken into account. Then, the observation of a large gravitational wave background from the electroweak phase transition would not necessarily rule out electroweak baryogenesis as the mechanism having generated the observed baryon asymmetry of the universe.

description: Background: Orthostatic tremor (OT) is a weight-bearing hyperkinetic disorder characterized by unsteadiness while standing that is relieved when sitting or walking.

Case report: A 66-year-old male presented with a 5 year-history of tremor in his abdomen, but only when he stood in a stationary position. The tremor disappeared when he stood or walked. On examination, he had palpable tremor in his rectus abdominis and gastrocnemius virtually instantaneously after standing. His electromyography findings confirmed the presence of a 12-Hz tremor in the tibialis anterior while standing, with subharmonics recorded in the external obliques and rectus abdominis.

Discussion: Our case illustrates an unusual presentation of OT. The diagnosis is supported by its characteristic frequency and specific appearance only during upright stance.
Investigation of the Noise Floor of the Standard PIV Cross-Correlation Algorithm

description: Particle image velocimetry (PIV) is a powerful measurement technique used to acquire instantaneous measurements of entire flow fields at a given instant in time. Quantifying the uncertainty and error in PIV is a critical part of realizing the full potential of PIV as a flow measurement technique.
The noise floor of PIV is the minimum amount of random error that can be achieved for a particular standard cross-correlation (SCC) algorithm. The noise floor of the SCC used by DaVis in correlating image pairs is explored. Two methods for creating image pairs for correlation are compared, namely pseudo image pairs and artificial image pairs. A common PIV experimental setup with seeded water in a glass tank was used to acquired images at dt approximately 0 seconds between images. The aperture or f# of the lens was varied in order to achieve a range of particle image diameters at two different magnifications. A Matlab code was written to upsample, shift and downsample the images by a prescribed, sub-pixel displacement. The shifted images were then imported into DaVis and correlated, resulting in displacement vector images. The random error of these images were calculated and each particle diameter is compared.
The random and bias errors of the DaVis and PRANA SCC algorithms were also compared for a fixed, optimum particle image diameter and multiple sub-pixel displacements between 0 and 1 pixel.
The Effect of Kurtosis on the Cross-Section of Stock Returns

description: In this study, I show an effect of the statistical fourth moment on stock returns. In the mean-variance framework, rational investors follow two strategies: optimize the mean{variance of return and diversify the portfolio. Regarding the first approach, investors intend to generate the maximum level of return while facing a constant level of risk (or, the standard deviation) of return. It is possible that firm specific risk can be concentrated in the portfolio. However, diversification of the assets can eliminate that (idiosyncratic) risk from the portfolio. After a long period of time, in a diversified portfolio the shape of the return distribution appears to be peaked around the average value of the return compared with that of the typical shape of the return distribution. If investors have a preference for skewness in their returns, they also can produce peakedness in the shape of the distribution. The statistical fourth moment (kurtosis) measures the magnitude of peakedness of the distribution. As the kurtosis of the distribution in- creases the distribution will appear more peaked. I find evidence that kurtosis positively and significantly predicts future stock returns over the period 1981-2011. The effect remains after controlling for other factors in multivariate regressions.

description: Background: The clinical spectrum of anti-glutamic acid decarboxylase (GAD) antibody-associated neurologic syndromes is expanding, with focal, generalized, and atypical forms.

Case Report: We describe a 59-year-old female showing continuous right lower limb myoclonus and mild encephalopathy. These symptoms started 2 weeks prior to evaluation. The patient had great improvement with intravenous steroids. An autoantibody panel was positive for anti-GAD.

Discussion: Various clinical manifestations, including myoclonus, may relate to anti-GAD antibodies. The treatment options available include symptomatic drugs, intravenous immunoglobulin, steroids, and other immunosuppressant agents.
Order and Peace: Samuel Seabury's Concept of Liberty
Creators: name: Feng, Cho-Chien
Publisher: name: Utah State University
Year: 2012

description: The idea of liberty has been the subject of incessant debate. People around the world define the concept of liberty in different ways. For example, supporters of gay rights claim that liberty gives homosexuals the right to marry, yet at the same time, conservatively-inclined people in the United States argue that their liberty is threatened when President Obama executes his plans for the health care system. People have argued about the meaning of liberty throughout the centuries. Although the focus of the debates seemed to be diverse, the spirit underlying the debates was always the same: expanding the realm of human liberty for outside groups. The history of early modern American freedom, Michal Jan Rozbicki concluded in his book, was “a lengthy chronicle of diverse groups pounding at the gates and demanding membership.”1 As historians continue to explore how different groups of people have claimed liberty for themselves, it becomes clear that liberty is not a self-evident right, but is instead a locus of conflict and contestation.

description: The presence of peripheral blood film acanthocytes can help narrow the differential diagnosis of a familial choreiform disorder. Acanthocytosis is associated with chorea–acanthocytosis (ChAc), McLeod syndrome, pantothenate kinase-associated neurodegeneration (PKAN), and Huntington’s disease-like 2 (HDL-2). Huntington disease (HD) can present at a similar age with a similar phenotype, but without acanthocytosis. We report the cases of three adult siblings with genetically confirmed ChAc, and discuss the unusual finding of a co-existing abnormal HD allele (CAG repeat expansion in the range of reduced penetrance) in two of these siblings.

description: The expansion of space, and other geometric properties of cosmological models, can be studied using geometrically defined notions of relative velocity. In this paper, we consider test particles undergoing radial motion relative to comoving (geodesic) observers in Robertson-Walker cosmologies, whose scale factors are increasing functions of cosmological time. Analytical and numerical comparisons of the Fermi, kinematic, astrometric, and the spectroscopic relative velocities of test particles are given under general circumstances. Examples include recessional comoving test particles in the de Sitter universe, the radiation-dominated universe, and the matter-dominated universe. Three distinct coordinate charts, each with different notions of simultaneity, are employed in the calculations. It is shown that the astrometric relative velocity of a radially receding test particle cannot be superluminal in any expanding Robertson-Walker spacetime. However, necessary and sufficient conditions are given for the existence of superluminal Fermi speeds, and it is shown how the four concepts of relative velocity determine geometric properties of the spacetime.

description: We introduce higher dimensions into the problem of Bose-Einstein condensates in a double-well potential, taking into account orbital angular momentum. We completely characterize the eigenstates of this system, delineating new regimes via both analytical high-order perturbation theory and numerical exact diagonalization. Among these regimes are mixed Josephson- and Fock-like behavior, crossings in both excited and ground states, and shadows of macroscopic superposition states.

description: This paper proposes a general class of regression models for continuous proportions when the data contain zeros or ones. The proposed class of models assumes that the response variable has a mixed continuous-discrete distribution with probability mass at zero or one. The beta distribution is used to describe the continuous component of the model, since its density has a wide range of different shapes depending on the values of the two parameters that index the distribution. We use a suitable parameterization of the beta law in terms of its mean and a precision parameter. The parameters of the mixture distribution are modeled as functions of regression parameters. We provide inference, diagnostic, and model selection tools for this class of models. A practical application that employs real data is presented.
