description: In more than four spacetime dimensions, a multiple Weyl-aligned null direction (WAND) need not be geodesic. It is proved that any higher-dimensional Einstein spacetime admitting a non-geodesic multiple WAND also admits a geodesic multiple WAND. All five-dimensional Einstein spacetimes admitting a non-geodesic multiple WAND are determined.

description: To safely dimension the top shielding for the Damping Ring of the DAPHNE Project, the neutron dose equivalents due to the skyshine effect as a function of distance from the machine building and of the altitude have been evaluated. The calculations were performed in two steps: Source definition and radiation transport. For the first step the code used was FLUKA. The transport of the emitted particles was simulated using the CERN version of the MORSE code. From the results obtained, it can be concluded that a 40 cm thick concrete roof makes the skyshine contribution to dose in the environment negligible, in normal operating conditions.

description: Antibiotic resistance in agricultural soils is a significant environmental and health challenge worldwide. To minimize the risk of antibiotic resistance, it is important to understand the fate and spread mechanism of antibiotics and antibiotic resistance genes (ARGs), and develop effective technologies to minimize their negative effects. In this work, we reviewed recent studies on the occurrence of antibiotic resistance in soil by different agricultural practices. The continuous land applications of manures and sewage sludge, and irrigation with wastewater contribute to the elevated antibiotic resistance in soil. The fate of antibiotic resistance from different interfaces are also discussed. In particular, the mechanisms of ARGs dissemination between bacteria are presented. Aerobic composting, and anaerobic and aerobic digestions of manure, sludge, or wastewater are found to be effective treatments to reduce antibiotic resistance into agricultural soils from the sources. Furthermore, strategies to alleviate antibiotic resistance in soil are proposed, and research directions on in-depth mechanisms are outlined to elucidate the antibiotic resistance decay in soil treatment processes. Although much progress has been made in understanding the links of antibiotic resistance between soil and human health, there are still many unknowns on the complex interactions between them.

description: The last phase transition predicted by the standard model of particle physics took place at the QCD scale $T\sim200$ MeV when the universe was about $t\sim10^{-5}$ seconds old and the Hubble radius was around 10 Km. In this paper, we consider the quark--hadron phase transition in the context of brane-world cosmology where our universe is a 3-brane embedded in a $m$-dimensional bulk and localization of matter on the brane is achieved by means of a confining potential. We study the behavior of the physical quantities relevant to the description of the early universe like the energy density, temperature and scale factor, before, during, and after the phase transition and investigate the effects of extrinsic curvature on the cosmological phase transition. We show that the brane-world effects reduce the effective temperature of the quark--gluon plasma and of the hadronic fluid. Finally, we discuss the case where the universe evolved through a mixed phase with a small initial supercooling and monotonically growing hadronic bubbles.

Theoretical relation between water flow rate in a vertical fracture and rock temperature in the surrounding massif

description: A steady-state analytical solution is given describing the temperature distribution in a homogeneous massif perturbed by cold water flow through a discrete vertical fracture. A relation is derived to express the flow rate in the fracture as a function of the temperature measured in the surrounding rock. These mathematical results can be useful for tunnel drilling as it approaches a vertical cold water bearing structure that induces a thermal anomaly in the surrounding massif. During the tunnel drilling, by monitoring this anomaly along the tunnel axis one can quantify the flow rate in the discontinuity ahead before intersecting the fracture. The cases of the Simplon, Mont Blanc and Gotthard tunnels (Alps) are handled with this approach which shows very good agreement between observed temperatures and the theoretical trend. The flow rates before drilling of the tunnel predicted with the theoretical solution are similar in the Mont Blanc and Simplon cases, as well as the flow rates observed during the drilling. However, the absence of information on hydraulic gradients (before and during drilling) and on fracture specific storage prevents direct predictions of discharge rates in the tunnel.
Tense, aspect, mood and evidentiality in Sasak, eastern Indonesia

description: The Sasak language is spoken on the island of Lombok (immediately east of Bali, Indonesia) by around 2.7 million speakers, roughly 85% of the population of Lombok, which was recorded as 3,169,050 in 2010. Sasak shows great internal variation, both geographical and social. Its complex linguistic ecology (Austin 2003) includes five ethnolinguistically named ‘dialects’ recognized by native speakers and named for the shibboleth terms for ‘like that-like this’ (i.e. Ngenó-ngené, Nggetó-nggeté, Menó-mené, Kutó-kuté, Meriaq-meriku). This paper is a preliminary outline of the expression of polarity, aspect, mood and evidentiality in the Sasak language spoken on the island of Lombok. It is based on analysis of elicited and textual materials from several Sasak varieties and illustrates the formal and semantic differences between them.

Year: 1968

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
EXAFS STUDIES ON NANOCRYSTALLINE MATERIALS WITH DOPED GRAIN BOUNDARIES

description: We present an EXAFS study of the local environment of Co dopant atoms in nanocrystalline Cu. Due to the low solubility of Co atoms in bulk Cu, these measurements yield information on the local atomic structure of grain boundaries in nanocrystalline Cu. Previous EXAFS studies on pure nanocrystalline metals have indicated an atomic arrangement in the grain boundary component exhibiting a broad distribution of interatomic spacings which differs from the atomic structure of the crystalline or glassy state. In the present investigation a significantly reduced coordination number around Co is found; also, the first shell bond length varies with dopant concentration from that typical of Co substitutional impurities in Cu to that of bulk Co. These results suggest that Co atoms substitute Cu atoms both in the disordered grain boundaries and in the lattice of the Cu-crystallites and/or form Co-precipitates.
Effects of Electric Fields on Heteronuclear Feshbach Resonances in Ultracold $^6\rm{Li}-^{87}\rm{Rb}$ Mixtures

description: The effects of combined external electric and magnetic fields on elastic collisions in ultracold Li--Rb mixtures is studied using recently obtained, experimentally verified potentials. Our analysis provides both quantitative predictions for and a detailed physical interpretation of the phenomena arising from electric-field-induced interactions. It is shown that the electric field shifts the positions of intrinsic magnetic Feshbach resonances, generates copies of resonances previously restricted to a particular partial-wave collision to other partial wave channels, and splits Feshbach resonances into multiple resonances for states of non-zero angular momenta. It was recently observed that the magnetic dipole-dipole interaction can also lift the degeneracy of a p-wave state splitting the associated p-wave Feshbach resonance into two distinct resonances at different magnetic fields. Our work shows that the splitting of the resonances produced by an applied electric field is more than an order of magnitude larger. This new phenomenon offers a complementary way to produce and tune an anisotropic interaction and to study its effect on the many-body physics of heteronuclear atomic gases.

description: Scholars and practitioners indicate that low employee work engagement (EWE) is currently one of the most alarming global economic problems. Indeed, Operating within resource constraints and confronting distinct challenges, SMEs heavily rely on leveraging their workforce effectively for sustainability and expansion, making EWE in SMEs a very important issue, given that leaving a job in this sector represents a very high cost. Therefore, the current study explores the correlation between emotional intelligence (EI), employee resilience (ER), and employee work engagement (EWE) in manufacturing SMEs in a developing country such as Saudi Arabia. Additionally, the mediating effect of ER on the relationship between EI and EWE in Saudi manufacturing SMEs. The theoretical framework is established on extant literature to accomplish these objectives, utilizing the Job Demands-Resources (JD-R) as an underpinning theory. To fulfill the study objectives, a quantitative cross-sectional survey method was employed to gather data from a population of 101,910 employees working in manufacturing SMEs in the eastern region of Saudi Arabia. By simple random sampling, questionnaires were randomly distributed to 383 manufacturing SME employees, yielding 331usable responses, achieving an impressive response rate of 84 percent. The collected data were analyzed using Partial Least Squares Structural Equation Modelling (PLS-SEM) to assess the study's hypotheses. The results indicate a significant and positive influence of EI and ER on EWE. Furthermore, EI was found a positive and significant impact on ER among Saudi manufacturing SME employees. Crucially, the findings reveal that ER partially mediates the relationship between EI and EWE. These findings contribute to the literature by highlighting the relevance of EI and ER as personal resources and abilities, in enhancing SME employees' work engagement. Understanding these components enables SMEs' decision-makers to optimize employees' resilience and work engagement.

Year: 2014

description: The term ‘Aslian’ refers to a distinctive group of approximately 20 Mon-Khmer languages spoken in Peninsular Malaysia and the isthmian parts of southern Thailand. This paper is concerned only with ‘Aslian languages’ in the narrow sense (genetically Mon-Khmer) and not ‘Orang Asli languages’ in general (a sociolinguistic term covering both Aslian and Aboriginal-Malay languages). Relatively little was known about the Aslian languages until the 1990s, when intensive field-research on them was taken up again after some thirty years of relative inattention. However, misinformation still attends much of the public discussion of the status, history, relationships and characteristics of these languages. This paper is aimed at redressing the situation by surveying what is currently known about their circumstances, coupled with an assessment of the scholarly research on which that information is based. The question of endangerment will also be discussed: some Aslian languages are in imminent danger of extinction while the survival of others is by no means assured, even if they may seem to be currently viable.

Year: 2014

description: The Kainji languages of north-central Nigeria, which constitute a major branch of the Benue-Congo language subgroup (Gerhardt 1989, Williamson & Blench 2000), have been largely ignored by academic linguists. The group includes approximately 60 languages divided geographically into three main areas. This article will discuss the branches of Kainji found in the northwest, namely Reshe, Lake, Kambari, Northwest, Kamuku and Shiroro, and reserve discussion of East Kainji and Basa for another paper. The article is organised as follows: Section 2 introduces the Kainji languages and provides some background on their speakers and the linguistic and language development work that has been carried out there. Section 3 discusses two important dimensions of ideological conflict in northern Nigeria, ethnicity and religion, while Section 4 outlines the shared historical background and cultural practices of the Kainji language communities. Section 5 provides evidence for the anti-Hausa language ideology held by many rural speakers of Kainji languages, and Section 6 makes recommendations for applied language documentation in the Kainji area.

description: This paper describes the past, present, and future of a remotely-sited, community-based language documentation project near the border between Namibia and Botswana, where the Ju|’hoan (ktz) and X’ao-’aen (aue) languages are spoken. The paper presents an example of reignited linguistic pride within a community which speaks an indigenous language in danger of being supplanted by more dominant ones. We review the various obstacles encountered and the ways in which the project managed to overcome them, paving the way for future new developments. Some of the issues and solutions are culture-specific, while others are widely applicable to similar projects. In Section 3 we outline some of the technical problems faced and solved in the course of the first decade of the Ju|’hoan Transcription Group (JTG), while in Section 4 other project problems are discussed. These include practical ones such as limitations in the existing Namibian school system, as well as physical problems of the remote location, and social and political problems stemming largely from the attempt to foster a specialized project within a still fiercely egalitarian, recently hunter-gatherer society, which puts high priority on making community-wide consensual decisions. The future of the Ju|’hoan Transcription Project will involve finding solutions to these...

description: Semiparametric models are often considered for analyzing longitudinal data for a good balance between flexibility and parsimony. In this paper, we study a class of marginal partially linear quantile models with possibly varying coefficients. The functional coefficients are estimated by basis function approximations. The estimation procedure is easy to implement, and it requires no specification of the error distributions. The asymptotic properties of the proposed estimators are established for the varying coefficients as well as for the constant coefficients. We develop rank score tests for hypotheses on the coefficients, including the hypotheses on the constancy of a subset of the varying coefficients. Hypothesis testing of this type is theoretically challenging, as the dimensions of the parameter spaces under both the null and the alternative hypotheses are growing with the sample size. We assess the finite sample performance of the proposed method by Monte Carlo simulation studies, and demonstrate its value by the analysis of an AIDS data set, where the modeling of quantiles provides more comprehensive information than the usual least squares approach.

description: In this paper, we provide the $O(ε)$ corrections to the hydrodynamic model derived by Degond and Motsch from a kinetic version of the model by Vicsek & coauthors describing flocking biological agents. The parameter $ε$ stands for the ratio of the microscopic to the macroscopic scales. The $O(ε)$ corrected model involves diffusion terms in both the mass and velocity equations as well as terms which are quadratic functions of the first order derivatives of the density and velocity. The derivation method is based on the standard Chapman-Enskog theory, but is significantly more complex than usual due to both the non-isotropy of the fluid and the lack of momentum conservation.

description: Discontinuities in elastic constants are detected at the superconducting transition of layered organic conductors κ-(BEDT-TTF)_{2}X by longitudinal and transverse ultrasonic velocity measurements. Symmetry arguments show that discontinuities in shear elastic constants can be explained in the orthorhombic compound only if the superconducting order parameter has a mixed character that can be of two types, either A_{1g}+B_{1g} or B_{2g}+B_{3g} in the classification of irreducible representations of the orthorhombic point group D_{2h}. Consistency with other measurements suggests that the A_{1g}+B_{1g} (d_{xy}+d_{z(x+y)}) possibility is realized. Such clear symmetry-imposed signatures of mixed order parameters have not been observed in other superconducting compounds.

description: We study the three-dimensional U(1) lattice gauge theory of a CP$^1$ spinon (Schwinger boson) field and a Higgs field. It is a bosonic $t$-$J$ model in slave-particle representation, describing the antiferromagnetic (AF) Heisenberg spin model with doped bosonic holes expressed by the Higgs field. The spinon coupling term of the action favors AF long-range order, whereas the holon hopping term in the ferromagnetic channel favors Bose-Einstein condensation (BEC) of holons. We investigate the phase structure by means of Monte-Carlo simulations and study an interplay of AF order and BEC of holes. We consider the two variations of the model; (i) the three-dimensional model at finite temperatures, and (ii) the two-dimensional model at vanishing temperature. In the model (i) we find that the AF order and BEC coexist at low temperatures and certain hole concentrations. In the model (ii), by varying the hole concentration and the stiffness of AF spin coupling, we find a phase diagram similar to the model (i). Implications of the results to systems of cold atoms and the fermionic $t$-$J$ model of strongly-correlated electrons are discussed.

Building community participation into documentation design: lessons learned in Sakun (Sukur)
Creators: name: Thomas, Michael F.
Publisher: name: Language Documentation and Description
Year: 2014

description: A successful language documentation project needs to balance the sometimes conflicting goals of all the project stakeholders in order to enhance everyone’s desired outcomes. Linguists have a wide range of motivations for archiving and analyzing languages, many of which have little to do with community goals of maintenance and development. It is argued here that while documentation and development goals may not always be one and the same, the goals of this documentation project are necessary precursors to the attainment of the Sakun community’s development goals. The participation of community members in the documentation provides the link for the community to take the results of the documentation and apply them to community initiated development efforts. This paper reports on the ongoing language documentation project at the UNESCO Sukur World Heritage Site, in Adamawa state, Nigeria, and the attempt to balance these potentially divergent motivations by integrating the community into the documentation project at a number of levels. The success of this project is the result of collaborative efforts between the local community and the researcher, support from representatives of a range of cultural and political organizations at the local, state and national level in Nigeria, and funding from the Hans...

description: The abundance of dark matter satellites and subhalos, the existence of density cusps at the centers of dark matter halos, and problems producing realistic disk galaxies in simulations are issues that have raised concerns about the viability of the standard cold dark matter (LambdaCDM) scenario for galaxy formation. This talk reviews these issues, and considers the implications for cold vs. various varieties of warm dark matter (WDM). The current evidence appears to be consistent with standard LambdaCDM, although improving data may point toward a rather tepid version of LambdaWDM - tepid since the dark matter cannot be very warm without violating observational constraints.

description: This paper explores the problem of community collaboration in applied language documentation in Africa, drawing on experiences from a documentation project currently underway in Cameroon. Three points will be highlighted: (i) the fact that outside linguists benefit from the support of a number of distinct communities, all of which are under-resourced and which can be assisted in ways specific to their needs, (ii) the importance of coming to a detailed understanding of the social significance of a given language in its local context in order to discover the most appropriate ways to support its maintenance, and (iii) the extent to which the primary assistance offered to a community should be narrowly ‘linguistic’ in nature.

description: Employing a medium-dependent quantum optics formalism and a Green function solution of Maxwell's equations, we study the enhanced spontaneous emission factors (Purcell factors) and Lamb shifts from a quantum dot or atom near the surface of a %embedded in a slow-light metamaterial waveguide. Purcell factors of approximately 250 and 100 are found at optical frequencies for $p-$polarized and $s-$polarized dipoles respectively placed 28\thinspace nm (0.02\thinspace $λ_{0}$) above the slab surface, including a realistic metamaterial loss factor of $γ/2π=2 \mathrm{THz}$. For smaller loss values, we demonstrate that the slow-light regime of odd metamaterial waveguide propagation modes can be observed and related to distinct resonances in the Purcell factors. Correspondingly, we predict unusually large and rich Lamb shifts of approximately -1 GHz to -6 GHz for a dipole moment of 50 Debye. We also make a direct calculation of the far field emission spectrum, which contains direct measurable access to these enhanced Purcell factors and Lamb shifts.

description: Fermionic alkaline-earth atoms have unique properties that make them attractive candidates for the realization of novel atomic clocks and degenerate quantum gases. At the same time, they are attracting considerable theoretical attention in the context of quantum information processing. Here we demonstrate that when such atoms are loaded in optical lattices, they can be used as quantum simulators of unique many-body phenomena. In particular, we show that the decoupling of the nuclear spin from the electronic angular momentum can be used to implement many-body systems with an unprecedented degree of symmetry, characterized by the SU(N) group with N as large as 10. Moreover, the interplay of the nuclear spin with the electronic degree of freedom provided by a stable optically excited state allows for the study of spin-orbital physics. Such systems may provide valuable insights into strongly correlated physics of transition metal oxides, heavy fermion materials, and spin liquid phases.

Aiming Perfectly in the Dark - Blind Interference Alignment through Staggered Antenna Switching

description: We propose a blind interference alignment scheme for the vector broadcast channel where the transmitter is equipped with M antennas and there are K receivers, each equipped with a reconfigurable antenna capable of switching among M preset modes. Without any knowledge of the channel coefficient values at the transmitters and with only mild assumptions on the channel coherence structure we show that MK/M+K-1 degrees of freedom are achievable. The key to the blind interference alignment scheme is the ability of the receivers to switch between reconfigurable antenna modes to create short term channel fluctuation patterns that are exploited by the transmitter. The achievable scheme does not require cooperation between transmit antennas and is therefore applicable to the MxK X network as well. Only finite symbol extensions are used, and no channel knowledge at the receivers is required to null the interference.

Access and accessibility at ELAR, an archive for endangered languages documentation
Creators: name: Nathan, David
Publisher: name: Language Documentation and Description

description: Language documentation, also known as documentary linguistics, is a subfield of linguistics that emerged in the 1990s as a response to predictions that the majority of human languages will disappear within a century (Krauss 1992). The new discipline aims to develop ‘methods, tools, and theoretical underpinnings for compiling a representative and lasting multipurpose record of a natural language’ (Gippert et al 2006: v). The issue of access to archive resources is multifaceted, and goes far beyond designating resources as open or closed. I have illustrated some of the advantages of custom solutions for a specific field – here, endangered languages documentation. Until now, access has more or less meant providing ‘insiders’ with the means to locate specialist materials by using constrained ontologies. ELAR has sought to help diverse audiences including ‘outsiders’ to access content they hope to find or perhaps never imagined finding. In doing so we are replacing a ‘stork and baby’ approach to archiving – deposit and abandon – with a platform for ongoing relationships and activities around the data. This does require an increased commitment on the part of depositors, but it is likely to result in greater participation amongst and support of speakers of endangered languages...

description: We report on the simulated performances of a non-homogeneous e.m. calorimeter based on a 5X_0 tracking section using CsI(Tl) fibres, followed by a 10 X_0 Pb-SCIFI head-on back section. Our study shows that such a technique is quite promising for the high-efficency detection of photons in the energy range of interest at a ϕ-factory machine.
Perturbations of Spacetime around a Stationary Rotating Cosmic String

description: We consider the metric perturbations around a stationary rotating Nambu-Goto string in Minkowski spacetime. By solving the linearized Einstein equations, we study the effects of azimuthal frame-dragging around the rotation axis and linear frame-dragging along the rotation axis, the Newtonian logarithmic potential, and the angular deficit around the string as the potential mode. We also investigate gravitational waves propagating off the string and propagating along the string, and show that the stationary rotating string emits gravitational waves toward the directions specified by discrete angles from the rotation axis. Waveforms, polarizations, and amplitudes which depend on the direction are shown explicitly.

description: Spectral properties of a fully compressible solar wind Hall Magnetohydrodynamic plasma are investigated by means of time dependent three dimensional Hall MHD simulations. Our simulations, in agreement with spacecraft data, identify a spectral break in turbulence spectra at characteristic length-scales associated with electromagnetic fluctuations that are smaller than the ion gyroradius. In this regime, our 3D simulations show that turbulent spectral cascades in the presence of a mean magnetic field follow an omnidirectional anisotropic inertial range spectrum close to $k^{-7/3}$. The onset of the spectral break in our simulations can be ascribed to the presence of nonlinear Hall interactions that modify the spectral cascades. Our simulations further show that the underlying charachteristic turbulent fluctuations are spectrally anisotropic, the extent of which depends critically on the local wavenumber. The fluctuations associated with length scales smaller than the ion gyroradius are highly compressible and tend to exhibit a near equipartition in the velocity and magnetic fields. Finally, we find that the orientation of velocity and magnetic field fluctuations critically determine the character of nonlinear interactions that predominantly govern a Hall MHD plasma, like the solar wind.

Archiving grammatical descriptions

description: Language documentation projects produce and collect audio, video, and textual data, which they usually deposit in archives. Documenters’ understanding of best practices in archiving the primary content of their domain has made considerable progress over recent years. Methods for archiving derived content, such as dictionaries and especially grammatical descriptions, have received less attention. In this paper, we explore what the goals of archiving grammatical descriptions are, and what tasks an archive has to fulfill. We first discuss a number of parameters which help us to classify archives with regard to the objects they host and the roles they play in their user community. We argue that the text of grammatical descriptions should be archived in a fashion which allows retrieval of individual elements such as sections, paragraphs, and examples, and that for this to work, grammatical descriptions have to be provided with semantic markup. We discuss the Text Encoding Initiative (TEI), originally a philological enterprise, and the TEI tools which are useful for this purpose. Grammatical descriptions contain a number of elements which are not yet found in TEI, and we identify and describe these. We then discuss how annotation of both legacy and future grammatical descriptions can be accomplished...
