description: Superconductivity in the iron pnictides develops near antiferromagnetism, and the antiferromagnetic (AF) phase appears to overlap with the superconducting phase in some materials such as BaFe2-xTxAs2 (where T = Co or Ni). Here we use neutron scattering to demonstrate that genuine long-range AF order and superconductivity do not coexist in BaFe2-xNixAs2 near optimal superconductivity. In addition, we find a first-order-like AF to superconductivity phase transition with no evidence for a magnetic quantum critical point. Instead, the data reveal that incommensurate short-range AF order coexists and competes with superconductivity, where the AF spin correlation length is comparable to the superconducting coherence length.

Exploring constrained quantum control landscapes
Creators: name: Moore, Katharine W.

Publisher: name: arXiv
Year: 2011
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The broad success of optimally controlling quantum systems with external fields has been attributed to the favorable topology of the underlying control landscape, where the landscape is the physical observable as a function of the controls. The control landscape can be shown to contain no suboptimal trapping extrema upon satisfaction of reasonable physical assumptions, but this topological analysis does not hold when significant constraints are placed on the control resources. This work employs simulations to explore the topology and features of the control landscape for pure-state population transfer with a constrained class of control fields. The fields are parameterized in terms of a set of uniformly spaced spectral frequencies, with the associated phases acting as the controls. Optimization results reveal that the minimum number of phase controls necessary to assure a high yield in the target state has a special dependence on the number of accessible energy levels in the quantum system, revealed from an analysis of the first- and second-order variation of the yield with respect to the controls. When an insufficient number of controls and/or a weak control fluence are employed, trapping extrema and saddle points are observed on the landscape. When the control resources are sufficiently flexible, solutions producing the globally maximal yield are found to form connected `level sets' of continuously variable control fields that preserve the yield. These optimal yield level sets are found to shrink to isolated points on the top of the landscape as the control field fluence is decreased, and further reduction of the fluence turns these points into suboptimal trapping extrema on the landscape. Although constrained control fields can come in many forms beyond the cases explored here, the behavior found in this paper is illustrative of the impacts that constraints can introduce.

description: We evaluate the exact one-loop partition function for fundamental strings whose world-surface ends on a cusp at the boundary of AdS_4 and has a "jump" in CP^3. This allows us to extract the stringy prediction for the ABJM generalized cusp anomalous dimension Gamma_{cusp}^{ABJM} (phi,theta) up to NLO in sigma-model perturbation theory. With a similar analysis, we present the exact partition functions for folded closed string solutions moving in the AdS_3 parts of AdS_4 x CP^3 and AdS_3 x S^3 x S^3 x S^1 backgrounds. Results are obtained applying to the string solutions relevant for the AdS_4/CFT_3 and AdS_3/CFT_2 correspondence the tools previously developed for their AdS_5 x S^5 counterparts.

description: Biological waste treatment technology is currently the world’s largest application process, and its functional achievement mainly relies on complex microbial communities. However, the microbial system in such engineered ecosystems has been considered a “black box.” Over the past decade, with the development of molecular biotechnology and next-generation sequencing technologies, the exploration of such “black boxes” has gradually deepened. In particular, the role of ecological forces in uncovering and regulating microbial communities has been largely recognized and has provided novel insights into the link between microbial communities and engineering objectives. However, the study of community ecology in engineered ecosystems is still in its early infancy and faces grand challenges in bridging engineering principles with microbial ecology theory. In this review, we discuss recent advances in the understanding of microbial community behavior in biological waste treatment systems, including biodiversity and its influencing factors, the role of neglected rare species, microbial interactions, and community assembly mechanisms. We emphasize the importance of these ecological perspectives in revealing and regulating microbial communities and functions, such as the enhancement of contaminant removal and operational stability in engineered ecosystems. In particular, cross-validation of the microbial community analysis results is necessary to yield valid real information to guide the improvement and stability of engineering ecosystem performance. Multi-omics approaches and synthetic community biology are preferred ways to link ecological theory and engineering objectives.

description: We take an analytic approach towards the framework of parametric resonance and apply it on preheating and locked inflation. A two-scalar toy model is analytically solved for the λϕ^2χ^2 coupling for the homogenous modes. The effects of dynamic universe background and backreaction are taken into account. We show the average effect of parametric resonance to be that χ's amplitude doubles for each cycle of ϕ. Our framework partly solves the preheating scenario, showing two distinct stages of preheating and making the parameters of preheating analytically calculable. It is demonstrated for slowroll inflation models, preheating is terminated, if by backreaction, typically in the 5th e-fold. Under our framework, a possible inhomogeneity amplification effect is also found during preheating, which both may pose strong constraints on some inflationary models and may amplify tiny existing inhomogeneities to the desired scale. For demonstration, we show it rules out the backreaction end of preheating of the quadratic slowroll inflation model with mass m\sim10^{-6}. For locked inflation, parametric resonance is found to be inhibited if ϕ has more than one real component.

The nuclear terrorism disconnect : electoral incentives and U.S. policy responses
Creators: name: Reed, Samuel Thomas
Publisher: name: University of British Columbia
Year: 2013

description: This thesis investigates the range of U.S. threat assessments of—and policy responses to—nuclear terrorism in the United States. It finds that a series of disconnects characterizes political elites’ and the American public’s views and relationships to the politics of nuclear terror. The salience of issues related to nuclear terrorism is not closely linked to the severity of the threat. In turn, the perceived severity of the threat is not strongly correlated with the counter nuclear terror policy response. This thesis assesses the degree of citizen competence in nuclear politics and the degree of elite responsiveness to mass opinion. It also evaluates the full range of elite threat assessments and identifies a number of contemporary trends in public opinion on nuclear terrorism. The thesis advances both domestic and international case studies of American policy responses to the threat of nuclear terrorism.

description: Nach Schätzungen des vorliegenden Berichts sind staatliche Käufe für mindestens zwölf Prozent der deutschen Treibhausgasemissionen verantwortlich. Diese entstehen vor allem im Zuge der Bereitstellung öffentlicher Dienstleistungen und von Bauinvestitionen. Durch umweltfreundliche öffentliche Beschaffung (Green Public Procurement, GPP) – die Berücksichtigung der CO₂-Bilanz von Gütern und Dienstleistungen bei der Vergabe öffentlicher Aufträge – können diese Emissionen gesenkt werden. Staatliche Bauinvestitionen, insbesondere die Infrastruktur, können zu einem Hotspot für die Bekämpfung des Klimawandels durch GPP werden. Doch nachhaltige Beschaffungspraktiken spielen in Deutschland noch immer eine begrenzte Rolle und sind nicht primär auf eine Reduktion von Emissionen ausgerichtet. Eine Befragung von öffentlichen Beschaffungsstellen zeigt, dass die technische Komplexität von GPP als Haupthemmnis wahrgenommen wird, verbunden mit geringen administrativen Kapazitäten. Der Gesetzgeber sollte darauf hinwirken, dass Klimakriterien ein höheres Gewicht zukommt sowie – vor allem auf kommunaler Ebene – Kapazitäten ausgeweitet werden und das Personal entsprechend geschult wird. Überregionale Beratungsstellen für nachhaltige Beschaffung können hierbei die kommunale Ebene unterstützen.

description: We consider the classical dynamics of two particles moving in harmonic potential wells and interacting with the same external environment (HE), consisting of N non-interacting chaotic systems. The parameters are set so that when either particle is separately placed in contact with the environment, a dissipative behavior is observed. When both particles are simultaneously in contact with HE an indirect coupling between them is observed only if the particles are in near resonance. We study the equilibrium properties of the system considering ensemble averages for the case N=1 and single trajectory dynamics for N large. In both cases, the particles and the environment reach an equilibrium configuration at long times, but only for large N a temperature can be assigned to the system.

description: The biological denitrification process is crucial for removing nitrogen and reducing nitrous oxide (N2O) emissions. To investigate the mechanism of action of key enzymes in the denitrification process, it is necessary to analyze the protein structure, active site, and conformational changes of denitrifying enzymes. X-ray crystallography, nuclear magnetic resonance (NMR), and cryogenic electron microscopy (Cryo-EM), as well as spectroscopic analyses such as Raman resonance and UV-vis, have been used to study the structure of denitrifying enzymes. However, practical application is limited by protein folding and assembly, as well as issues of purity, concentration, and homogeneity. This review summarizes the biochemical properties of the four denitrifying enzymes and typical purification methods. Additionally, this review emphasizes important factors to consider during protein expression, crude extract, and chromatographic purification. It also provides insight into the future development of protein purification methods for denitrifying enzymes. This review aims to bridge the gap between the complex biochemical process of denitrifying enzymes and the technical intricacies of protein purification, with the ultimate goal of reducing N2O emissions in ecosystems.

description: We investigate a Coulomb gas in a potential satisfying a weaker growth assumption than usual and establish a large deviation principle for its empirical measure. As a consequence the empirical measure is seen to converge towards a non-random limiting measure, characterized by a variational principle from logarithmic potential theory, which may not have compact support. The proof of the large deviation upper bound is based on a compactification procedure which may be of help for further large deviation principles.

Primordial Non-Gaussianity in the Forest: 3D Bispectrum of Ly-alpha Flux Spectra Along Multiple Lines of Sight

Publisher: name: arXiv

description: We investigate the possibility of constraining primordial non-Gaussianity using the 3D bispectrum of Ly-alpha forest. The strength of the quadratic non-Gaussian correction to an otherwise Gaussian primordial gravitational field is assumed to be dictated by a single parameter fnl. We present the first prediction for bounds on fnl using Ly-alpha flux spectra along multiple lines of sight. The 3D Ly-$α$ transmitted flux field is modeled as a biased tracer of the underlying matter distribution sampled along 1D skewers corresponding to quasars sight lines. The precision to which fnl can be constrained depends on the survey volume, pixel noise and aliasing noise (arising from discrete sampling of the density field). We consider various combinations of these factors to predict bounds on fnl. We find that in an idealized situation of full sky survey and negligible Poisson noise one may constrain fnl ~ 23 in the equilateral limit. Assuming a Ly-alpha survey covering large parts of the sky (k_{min} = 8 * 10^{-4} Mpc^{-1}) and with a quasar density of \bar n = 5 * 10^{-3} Mpc^{-2} it is possible to constrain fnl ~ 100 for equilateral configurations. The possibility of measuring fnl at a precision comparable to LSS studies maybe useful for joint constraining of inflationary scenarios using different data sets.

title: Cultural Adaptability of Students Attending Culturally Diverse and Non-Culturally Diverse Dental Hygiene Programs
Creators: name: Magee, Katrina White
Publisher: name: Old Dominion University Libraries
Year: 1999

description: The purpose of this descriptive investigation was to determine the cultural adaptability of students attending culturally diverse and nonculturally diverse dental hygiene programs throughout the U.S. The dental hygiene schools were identified according to their ethnic diversity as reported by the ADA Commission on Dental Accreditation in the 1996-1997 Survey of Dental Hygiene Education Programs. Once the programs were identified, a random sample was taken from the diverse and non-diverse dental hygiene programs. A 50-item inventory, the Cross-Cultural Adaptability Inventory (CCAI), was mailed to the participating dental hygiene programs. One-hundred eighty-eight students represented U.S. dental hygiene programs in the following regions: Mid-Atlantic, South, Southeast, Southwest, Central, Northcentral and Northwest. The unpaired t-test was utilized to examine the differences between the groups on overall cultural adaptability and on its four dimensions: emotional resilience, flexibility/openness, perceptual acuity, and personal autonomy. Group mean and standard deviation scores were compared with the CCAI norm group scores. The results revealed no significant difference in the overall cultural adaptability of students attending either a culturally diverse or non-culturally diverse dental hygiene program. However, both groups' overall scores were significantly lower than the CCAI norm group. The culturally diverse group had significantly lower scores in flexibility/openness (p = .054) and perceptual acuity (p = .021) and significantly higher scores in emotional resilience (p = .000) when compared to the non-culturally diverse group. Scores in the dimension of emotional resilience and flexibility/openness were lower than the CCAI norm group, and scores in the dimension of perceptual acuity and personal autonomy were comparable with the CCAI norm group. There was no statistically significant difference between the culturally diverse and nonculturally diverse groups in the personal autonomy dimension. Findings suggest that dental hygiene students need more education in and experience with diversity issues. With low scores in the dimension of emotional resilience and flexibility/openness, students may lack the confidence and knowledge to cope with cross-cultural healthcare situations. However, the similar personal autonomy scores of the culturally diverse and non-culturally diverse students suggest that they already possess a strong sense of identity, responsibility, and respect for others.

description: Entanglement between macroscopically populated states can easily be created by combining a single photon and a bright coherent state on a beam-splitter. Motivated by the simplicity of this technique, we report on a method using displacement operations in the phase space and basic photon detections to reveal such an entanglement. We demonstrate through preliminary experimental results, that this eminently feasible approach provides an attractive way for exploring entanglement at various scales, ranging from one to a thousand photons. This offers an instructive viewpoint to gain insight into the reasons that make it hard to observe quantum features in our macroscopic world.

description: Violation of Lorentz invariance (VLI) has been suggested as an explanation of the superluminal velocities of muon neutrinos reported by OPERA. In this note we show that the amount of VLI required to explain this result poses severe difficulties with the kinematics of the pion decay, extending its lifetime and reducing the momentum carried away by the neutrinos. We show that the OPERA experiment limits $α= (v_ν- c)/c < 4 \times 10^{-6}$. We then take recourse to cosmic ray data on the spectrum of muons and neutrinos generated in the earth's atmosphere to provide a stronger bound on VLI: $(v-c)/c < 10^{-12}$.

description: We investigate the parity-violating $πNN$ Yukawa coupling constant $h^1_{πNN}$ within the framework of the SU(2) chiral quark-soliton model, based on the $ΔS=0$ effective weak Lagrangian derived within the same framework. We find that the parity-violating $πNN$ coupling constant is about $1\times10^{-8}$ at the scale of 1 GeV. The results of $h_{πNN}^1$ turn out to be sensitive to the Wilson coefficient. We discuss how the gluonic renormalization supresses the parity-violating $πNN$ coupling constant.

Bioavailability assessment of trace metal contaminants in urban soils and partitioning of zinc, cadmium, lead, nickel, and copper in the roots, shoots, foliage, and seeds of Chenopodium quinoa
Creators: name: Thomas, Elisabeth Chere

description: This paper presents two studies on urban soils in Vancouver – the first is a case study for assessment of trace metals in urban soils, with particular emphasis on brownfield reclamation and food production. Three single-extraction procedures are evaluated for their usefulness for identifying the bioavailable fractions of trace metals in soil. Plant-available Zn, Cd, Pb, Ni, and Cu were estimated using elemental analysis, pH, organic matter, and soil texture. Specific geochemical factors such as oxidizing conditions and the presence of Fe-, Al-, and Mn-oxides suggest trace metal mobility in the soils. The use of 0.1M HCl for estimating the risk of trace metal bioaccumulation in crop urban plants is recommended. The second study assesses selected phytoremediation technology for removing trace metals from soil through successive cultivation of trace metal-accumulating crop plants. A pot study was conducted using Chenopodium quinoa (quinoa) to extract Zn, Cd, Pb, Ni, and Cu from variously spiked brownfield soil. Chenopodium quinoa is a grain that may be a high-value specialty crop in British Columbia. Previous research suggested that Chenopodium quinoa may be a useful plant for phytoextraction of trace metals. The reasons for using quinoa in the present experiment are twofold – (1) to evaluate potential human health risks involved with growing a metal-accumulating crop in potentially contaminated urban soils, and (2) to assess the above-ground partitioning and accumulation of trace metals for evaluating the usefulness of Chenopodium quinoa for phytoextraction in Vancouver, British Columbia. It was found that quinoa is a hyperaccumulator and there is a potential concern that grains may contain harmful levels of trace metals for human consumption.

description: Noch stützen günstige Bedingungen auf den Arbeitsmärkten und ein dadurch steigender privater Konsum die Weltwirtschaft. Allerdings bremsen weiterhin Handelskonflikte und politische Unsicherheiten die Investitionstätigkeit, so dass insbesondere die fortgeschrittenen Volkswirtschaften nur wenig wachsen. In den Schwellenländern, vor allem in Indien, beschleunigt sich dagegen das Wachstum. Auch in den kommenden beiden Jahren wird die Wirtschaft insgesamt wohl nur verhalten expandieren. Trotz guter Finanzierungsbedingungen ist damit zu rechnen, dass die Investitionstätigkeit zunächst träge bleibt und vor allem der Konsum die Konjunktur stützt. Gegen Ende des Prognosezeitraums dürfte der private Verbrauch von einer wieder anziehenden Investitionstätigkeit und einem sich wieder belebenden Handel als wichtigster Wachstumstreiber abgelöst werden. Weltweit wird die Wirtschaft in diesem Jahr wohl um 3,6 Prozent und in den beiden kommenden Jahren um jeweils 3,7 Prozent wachsen. Auch wenn sich die Zollstreitigkeiten zwischen den USA und China etwas entspannt haben, bleiben die abwärts gerichteten Risiken anhaltend hoch. Weitere US-Zölle und die Unwägbarkeiten eines Brexit drohen, die Konjunktur zu schwächen.

description: In many domains, data measurements can naturally be associated with the leaves of a tree, expressing the relationships among these measurements. For example, companies belong to industries, which in turn belong to ever coarser divisions such as sectors; microbes are commonly arranged in a taxonomic hierarchy from species to kingdoms; street blocks belong to neighborhoods, which in turn belong to larger-scale regions. The problem of tree-based aggregation that we consider in this article asks which of these tree-defined subgroups of leaves should really be treated as a single entity and which of these entities should be distinguished from each other. We introduce the false split rate, an error measure that describes the degree to which subgroups have been split when they should not have been. While expressible as the false discovery rate in a special case, we show that these measures can be quite different for the general tree structures common in our setting. We then propose a multiple hypothesis testing algorithm for tree-based aggregation, which we prove controls this error measure. We focus on two main examples of tree-based aggregation, one which involves aggregating means and the other hich involves aggregating regression coefficients. Supplementary materials for this article are available online, including a standardized description of the materials available for reproducing the work.

description: With an easily applicable criterion based on permutation symmetries of (identically prepared) replicas of quantum states we identify distinct entanglement classes in high-dimensional multi- partite systems. The different symmetry properties of inequivalent states provide a rather intuitive picture of the otherwise very abstract classification of many-body entangled states.
