description: Motivated by the recent experimental observation of long range ferromagnetic order at a relatively high temperature of 200K in the Fe-doped ZnGa$_2$O$_4$ semiconducting spinel, we propose a possible mechanism for the observed ferromagnetism in this system. We show, supported by band structure calculations, how a model similar to the double exchange model can be written down for this system and calculate the ground state phase diagram for the two cases where Fe is doped either at the tetrahedral position or at the octahedral position. We find that in both cases such a model can account for a stable ferromagnetic phase in a wide range of parameter space. We also argue that in the limit of high Fe$^{2+}$ concentration at the tetrahedral positions a description in terms of a two band model is essential. The two $e_g$ orbitals and the hopping between them play a crucial role in stabilizing the ferromagnetic phase in this limit. The case when Fe is doped simultaneously at both the tetrahedral and the octahedral position is also discussed.

description: In an effort to address integrability breaking in cold gas experiments, we extend the integrable hydrodynamics of the 1d Lieb-Liniger model with two additional components representing the population of atoms in the first and second transverse excited states, thus enabling a description of quasi-1d condensates. Collisions between different components are accounted for through the inclusion of a Boltzmann-type collision integral in the hydrodynamic equation. Contrary to standard generalized hydrodynamics, our extended model captures thermalization of the condensate at a rate consistent with experimental observations from a quantum Newton's cradle setup.

description: Frustrated quantum $XXZ$ spin chains with the next-nearest-neighbor (NNN) couplings are typically deterministic many-body systems exhibiting Gaussian orthogonal ensemble (GOE) spectral statistics. We investigate energy diffusion for these spin chains in the presence of a periodically oscillating magnetic field. Diffusion coefficients are found to obey the power law with respect to both the field strength and driving frequency with its power varying depending on the linear response and non-perturbative regimes. The widths of the linear response and the non-perturbative regimes depend on the strength of frustrations. We have also elucidated a mechanism for oscillation of energy diffusion in the case of weakened frustrations.

Stochastic resonance in thalamic neurons and resonant neuron models
Creators: name: Reinker, Stefan
Publisher: name: University of British Columbia
Year: 2009

description: Neurons of the thalamus are major participants in gating sensory information for relay to the neocortex. Thalamic neurons are crucially involved in rhythmogenesis which determines the sleep/wake cycle. These roles require critical involvement of a T-type calcium current, conferring a frequency preference in response to subthreshold signals. We examine the interactions of this membrane resonance and noise using whole-cell patch clamp recordings in thalamocortical and reticular neurons of rat brain slices. We perform Monte-Carlo simulations and mathematical analysis using Hodgkin-Huxley-type and polynomial models of resonant neurons. We demonstrate stochastic resonance (SR) as maximal coherence between the input and stochastic output at intermediate noise levels. SR is measured by determining the signal-to-noise ratio under sine wave inputs, and from the reliability of detection measure under a-function inputs. In the experiments and neuron models with T-current, we demonstrate subthreshold resonance at 2-3 Hz, as well as noise dependent frequency dependence of SR for sine wave inputs. The simpler Hindmarsh-Rose model has a similar SR. This model also shows improved detection when the delay of consecutive EPSPs matches the preferred frequency. We show that the preferred frequency of the subthreshold and stochastic resonances depends on the time scale of the slow variable. The stochastic frequency preference arises from modulation of the firing probability of the fast subsystem. We develop a simple linear integrate-and-fire model with subthreshold resonance, which retains the main features of the more complicated models. An analytical solution of the stochastic equations shows that the eigenvalues determine frequency preferences in subthreshold resonance and stochastic resonance. SR can occur even with only noise. This autonomous SR depends on the resonance in our experiments and models. We demonstrate that preferred stochastic firing in the single neuron model translates into synchronized behaviour in a noisy network of resonant neuron models. With inhibitory synaptic coupling, noise can extend the parameter range of oscillations. With excitatory synaptic coupling, noise produces synchronized oscillations of the quiescent deterministic network. We speculate that combined subthreshold membrane resonance and stochastic resonance have physiological utility in coupling synaptic activity to preferred firing frequency, and in network synchronization under noise.

description: The objective of this paper is to explore the overall effects of further trade liberalization and the implemented CAP reforms on EU agricultural production, imports and exports within different EU regions by using the Global Trade Analysis Project (GTAP) model. The GTAP model is used to compare a lower tariff reduction formula (EU Proposal) with a higher reduction formula (US Proposal) in order to show how sensitive the examined agricultural commodity/sector is to the different tariff reduction formulae. This analysis reveals that EU imports would escalate and EU exports would plummet with declining EU production because of trade liberalization and domestic policy reforms in the EU agricultural markets and sectors.

description: Nodoscarus quadrisetatus gen. et sp. nov.
(Fig. 438)
Type material. Holotype ♀ (dissected and mounted on a slide, MNHN-IU-2014-21461) from Leptoclinides robiginis Monniot, F., 1989, south lagoon, New Caledonia.
Etymology. The specific name refers to the presence of four setae on the mandible.
Descriptionoffemale. Body (Fig. 438A) vermiform, elongate, cylindrical, unsegmented, almost straight, surface densely covered with fine setules (setules not shown in Fig. 438A, B). Bodylength 6.25 mm; body width 0.93 mm in middle. Paired convoluted ovaries, occupying 70% of body length, visible through body wall. Body tapering slightly anteriorly. Posterior end of body (Fig. 438B) bilobed, with shallow median (anal) incision.
Rostrum absent (Fig. 438C). Antennule (Fig. 438C) as broad, semicircular lobe, surface covered with fine setules plus 1 or 2 small setae apically. Antenna (Fig. 438D) stout, 3-segmented: coxa short; basis only slightly longerthan wide, unarmed; endopod about 1.4 times longer than wide (24×17 μm): armed with 1 subdistal and 3 small distal setae, plus short, stout terminal claw, half as long as endopod.
Labrum not discernible. Only 2 pairs of mouthparts present. Mandible (first pair, Fig. 438E) lobate, tipped with 4 naked setae. Maxillule (second pair, Fig. 438F) lobate, tipped with 2 setae. Large, anteriorly-directed, post-oral protuberance present posterior to oral region (Fig. 438C). Maxillae, maxillipeds, and legs absent.
Male. Unknown.
Remarks. Nodoscarus quadrisetatus gen. et sp. nov. is best compared with N. senisetatus gen. et sp. nov., because both of these two species retain only two pairs of mouthparts and share the presence of 2 setae on the second pair (the maxillules). The new species can be distinguished from N. senisetatus gen. et sp. nov. by the lack of a rostrum and by the possession of 4 setae on the mandible (vs. 6 setaein N. senisetatus gen. etsp. nov.).

description: Tianjin, China’s fifth largest city, suffers from severe environmental problems due to a high prevalence of plastic bag usage. This problem occurs in China’s other major cities as well. On June 1, 2008, a law requiring large retail stores in China to charge for bags was enacted in an attempt to curtail plastic bag consumption. As a result, many plastic bag manufacturing plants were closed. However, because of the wide-spread usage of plastic bags, they are still being manufactured and consumed. It is possible that the current plastic bag cost of 0.3 CNY is too low to change customers’ consumptive behavior. The purpose of this study is to explore people’s attitudes regarding the substitution of plastic bags with bags made from alternative materials, and their willingness to pay for such substitutes. This study used a conjoint choice experiment to measure Tianjin residents’ preferences for degradable and non-plastic materials bags. The results show that most people do not like non-degradable plastic bags and would use bags made of other materials if they were sold at a reasonable price. Based on the latent class and socio-demographic segmentation results, there are preference distinctions among age groups. Also, there are niche markets for paper, cloth, and degradable plastic bags where costs are of a lesser concern in consumer decisions. Manufacturers can use this information to more efficiently manufacture appropriate bags for different markets. This will help maximize revenue while continuing to meet demands.

description: A successful treating of a single, national, market through new challenges of marketing management is notably different than treating of the global market. The paper provides the case study of Gideon Multimedia, IT firm from Croatia. The company’s main product is mobiExplore, touristic guide platform for mobile phones. The application could be adapted to different marketplaces - global and national, for different countries. Because of different dynamic of the growth of national mobile markets even the global marketing strategy for the mobiExplore applications needs to be adapted to each national case. Establishing of the national strategy needs to be adapted through market research of the local market. The paper argues that customized for UK market mobiExplore solutions has proved correct and indicate on advantages of the company’s marketing strategies for single market.

Haplostatus

description: Haplostatus Illg & Dudley, 1961
Diagnosis. Body vermiform, cylindrical, without any metameric division. Urosome not demarcated from prosome, indistinctly 3-segmented. Anal somite tipped with pair of claws. Rostrum distinct, semicircular. Antennule as unsegmented lobe. Antenna 2-segmented. Antennae and vestigial mouthparts positioned within pre-oral cavity. Labrum distinct. Mouthparts absent or represented by 1 pair of small, bimerous lobes. Legs absent.
Type species. Haplostatus incubatrix Illg & Dudley, 1961 by original designation.
Remarks. The discovery of a second species enables us to better define the genus Haplostatus. In both species the urosome is segmented and carries a pair of claws posteriorly on the anal somite, and the antennae and mouthparts are located within a pre-oral cavity. These are the major diagnostic features of Haplostatus. The genera Pholeterides and Sicyodelphys were described as possessing a 3- or 4-segmented urosome, terminating in a pair of claws on the anal somite, as in Haplostatus, but these two genera both have legs, unlike Haplostatus.

description: It is pointed out that decays of the type $B \to D \bar{D}$ have no factorizable contributions, unless at least one of the charmed mesons in the final state is a vector meson. The dominant contributions to the decay amplitudes arise from chiral loop contributions and tree level amplitudes generated by soft gluon emissions forming a gluon condensate. We predict that the branching ratios for the processes $\bar B^0 \to D_s^+ D_s^-$, $\bar B^0 \to D_s^{+*} D_s^- $ and $\bar B^0 \to D_s^+ D_s^{-*}$ are all of order $(3- 4) \times 10^{-4}$, while $\bar B^0 \to D_s^{+*} D_s^{-*}$ has a branching ratio 5 to 10 times bigger. We emphasize that the branching ratios are sensitive to $1/m_c$ corrections.

Primordial black holes from cosmic necklaces

description: Cosmic necklaces are hybrid topological defects consisting of monopoles and strings. We argue that primordial black holes(PBHs) may have formed from loops of the necklaces, if there exist stable winding states, such as coils and cycloops. Unlike the standard scenario of PBH formation from string loops, in which the kinetic energy plays important role when strings collapse into black holes, the PBH formation may occur in our scenario after necklaces have dissipated their kinetic energy. Then, the significant difference appears in the production ratio. In the standard scenario, the production ratio $f$ becomes a tiny fraction $f\sim 10^{-20}$, however it becomes $f \sim 1$ in our case. On the other hand, the typical mass of the PBHs is much smaller than the standard scenario, if they are produced in the same epoch. As the two mechanisms may work at the same time, the necklaces may have more than one channel of the gravitational collapse. Although the result obtained in this paper depends on the evolution of the dimensionless parameter $r$, the existence of the winding state could be a serious problem in some cases. Since the existence of the winding state in brane models is due to the existence of a non-tivial circle in the compactified space, the PBH formation can be used to probe the structure of the compactified space. Black holes produced by this mechanism may have peculiar properties.

description: Recent experiments have shown that highly efficient energy transfer can take place in organic nanocrystals at extremely low acceptor densities. This striking phenomenon has been ascribed to the formation of exciton polaritons thanks to the photon confinement provided by the crystal itself. We propose an alternative theoretical model that accurately reproduces fluorescence lifetime and spectrum measurements in these systems without such an assumption. Our approach treats molecule-photon interactions in the weak-coupling regime, and describes the donor and acceptor population dynamics by means of rate equations with parameters extracted from electromagnetic simulations. The physical insight and predictive value of our model also enables us to propose nanocrystal configurations in which acceptor emission dominates the fluorescence spectrum at densities orders of magnitude lower than the experimental ones.

description: Nation-wide Sentinel-2 mosaics were used with National Forest Inventory (NFI) data for modelling and subsequent mapping of spruce, pine and deciduous forest in Norway in 16 m $\times$ 16 m resolution. The accuracies of the best model ranged between 74% for spruce and 87% for deciduous forest. An overall accuracy of 90% was found on stand level using independent data from more than 42.000 stands. Errors mostly resulting from a forest mask reduced the model accuracies by approximately 10%. Nonetheless, efficiencies of national forest area estimates increased by 20% to 50% for model-assisted (MA) estimates and up to 90% for poststratification (PS). Greater minimum number of observations, however, constrained the use of PS. For estimates of sub-populations (municipalities), efficiencies improved by up to a factor of 8. However, even for municipalities with a decent number of NFI plots, direct NFI estimates were sometimes more precise than MA estimates. PS estimates were always more precise than direct and MA estimates but were applicable in fewer municipalities. The tree species prediction map is freely available as part of the Norwegian forest resource map and is used, among others, to improve maps of other variables of interest such as timber volume and biomass.

description: Using first-principles calculations, we analyze the evolution of the electronic structure and magnetic properties of infinite-layer nickelates RNiO$_2$ (R= rare-earth) as R changes across the lanthanide series from La to Lu. By correlating these changes with in-plane and out-of-plane lattice parameter reductions, we conclude that the in-plane Ni-O distance is the relevant control parameter in infinite-layer nickelates. An antiferromagnetic ground state is obtained for all RNiO$_2$ (R=La-Lu). This antiferromagnetic state remains metallic across the lanthanide series and is defined by a multiorbital picture with low-energy relevance of a flat Ni-d$_{z^2}$ band pinned at the Fermi level, in contrast to cuprates. Other non-cuprate-like properties such as the involvement of R-$d$ bands at the Fermi level, a large charge transfer energy, and a suppressed superexchange are robust for all RNiO$_2$ materials.

description: This study is based on the assumption that “a happy worker is a productive worker”. The research was conducted to identify the significance of those factors that lead towards job satisfaction and commitment of employees working in the telecom sector of Pakistan. The associations among pay and benefits, performance appraisal system, career development and management, supervision and collegiality and open communication (independent variables) were investigated with job satisfaction (dependent variable). The relationship between job satisfaction (dependent variable) and job commitment (outcome) was also hypothesized. Through questionnaire survey responses from 221 employees working at managerial and non-managerial positions were collected, which showed the significant association of supervision and collegiality and open communication on job satisfaction. Furthermore, job satisfaction was also found highly correlated and dependent upon job commitment. Managerial implications and conclusions are presented based upon these results.

Diagnosis. Body stout, maggot-shaped, divisible into cephalosome, metasome, and urosome. Cephalosome incompletely articulated from metasome, with expanded ventral region. Freeurosome small, indistinctly 2- segmented, consisting of genital somite and unsegmented abdomen bearing caudal rami. Rostrum distinct. Antennule 2-segmented with setae on distal segment. Antenna 3-segmented, consistingof short coxa, basis, and unsegmented endopod bearing small terminal claw. Labrum lobate. Mouthparts absent. Three pairs of large ventral lobes present in oral region. Legs 1–4 absent. Leg 5 transformed to horn-like, pointed process bearing 1 minute seta proximally on outer margin.
Type species. Chilodelphys cerasta gen. et sp. nov. by original designation.
Etymology. The name is derved from the Greek chil (=lip) plus - delphys, and alludes to the presence of three pairs of lip-like swellings in the oral region.
Remarks. The new genus is characterised by its autapomorphic feature, the possession of the three pairs of large lobes in the oral region. It is possible that these lobes representtransformedmouthparts butwithoutthe additional evidence provided by, for example, a series of ontogenetic stages or the presence of recognizable setation elements, we prefer to use a neutral terminology. Despite the lack of mouthparts and legs 1–4, a transformed leg 5 and a distinct free urosome bearing caudal rami are present.

description: Recently, much research concerning the combination of nano-scale waveguides with nano-crystals and other nano-particles has been reported, because of possible applications in the field of quantum information and communication. The most useful and convenient method to verify the nature of such systems is optical detection. However, due to the diffraction limit, optical identification of characteristics such as particle type, particle position, etc is difficult or impossible. However, if such particles are placed on a waveguide, the coupling of scattered light to the waveguide guided modes can reveal the information about the particles. Here we consider how illumination with light of arbitrary polarization can reveal the difference between isotropic and non-isotropic nano-particles placed on the surface of an optical nanofiber. Specifically, we measure the polarization response function of gold nano-rods (GNRs) on an optical nanofiber surface and show that it is qualitatively different to that for gold nano-spheres (GNSs). This experimental technique provides a simple new tool for the optical characterization of hybrid nano-optical devices.

description: Using imaging from the Hubble Space Telescope, we derive surface brightness profiles for ultra-compact dwarfs in the Fornax cluster and for the nuclei of dwarf elliptical galaxies in the Virgo cluster. Ultra-compact dwarfs are more extended and have higher surface brightnesses than typical dwarf nuclei, while the luminosities, colors, and sizes of the nuclei are closer to those of Galactic globular clusters. This calls into question the production of ultra-compact dwarfs via ``threshing'' whereby the lower surface brightness envelope of a dwarf elliptical is removed by tidal processes, leaving behind a bare nucleus. Threshing may still be a viable model if the relatively bright Fornax ultra compact dwarfs considered here are descended from dwarf ellipticals whose nuclei are at the upper end of their luminosity and size distributions.

description: Modern cosmological analyses of galaxy-galaxy lensing face a theoretical systematic effect arising from the non-locality of the observed galaxy-galaxy lensing signal. Because the predicted tangential shear signal at a given separation depends on the physical modeling on all scales internal to that separation, systematic uncertainties in the modeling of non-linear small scales are propagated outwards to larger scales. Even in the absence of other limiting factors, this systematic effect alone can necessitate conservative small-scale cuts, resulting in significant losses of information in the tangential shear data vector. We construct a simple linear transformation of the observable that removes this non-locality, enabling more aggressive small-scale cuts for a given theoretical model. Our modified galaxy-galaxy lensing observable makes it possible to include observations on significantly smaller scales than those under the standard approach in cosmological analyses. More importantly, it ensures that the cosmological signal contained within the observable is exclusively drawn from well-understood physical scales.

description: We present a general study of oscillations in suspended one-dimensional elastic systems clamped at each end, exploring a wide range of slack (excess length) and downward external forces. Our results apply directly to recent experiments in nanotube and silicon nanowire oscillators. We find the behavior to simplify in three well-defined regimes which we present in a dimensionless phase diagram. The frequencies of vibration of such systems are found to be extremely sensitive to slack.

description: The Standard Model Effective Field Theory (SMEFT) provides a consistent framework for comparing precision measurements at the LHC to the Standard Model. The observation of statistically significant non-zero SMEFT coefficients would correspond to physics beyond the Standard Model (BSM) of some sort. A more difficult question to answer is what, if any, detailed information about the nature of the underlying high scale model can be obtained from these measurements. In this work, we consider the patterns of SMEFT operators present in five example models and discuss the assumptions inherent in using global fits to make BSM conclusions. We find that including renormalization group effects has a significant impact on the interpretation of the results. As a by-product of our study, we present an up-dated global fit to SMEFT coefficients in the Warsaw basis including some next-to-leading order QCD corrections in the SMEFT theory.

The metric projections onto closed convex cones in a Hilbert space

description: We study the metric projection onto the closed convex cone in a real Hilbert space $\mathscr{H}$ generated by a sequence $\mathcal{V} = \{v_n\}_{n=0}^\infty$. The first main result of this paper provides a sufficient condition under which we can identify the closed convex cone generated by $\mathcal{V}$ with the following set: \[ \mathcal{C}[[\mathcal{V}]]: = \bigg\{\sum_{n=0}^\infty a_n v_n\Big|a_n\geq 0,\text{ the series }\sum_{n=0}^\infty a_n v_n\text{ converges in $\mathscr{H}$}\bigg\}. \] Then, by adapting classical results on general convex cones, we give a useful description of the metric projection of a vector onto $\mathcal{C}[[\mathcal{V}]]$. As applications, we obtain the best approximations of many concrete functions in $L^2([-1,1])$ by polynomials with non-negative coefficients.

description: We explicitly derive, following a Noether-like approach, the criteria for preserving Poincare invariance in noncommutative gauge theories. Using these criteria we discuss the various spacetime symmetries in such theories. It is shown that, interpreted appropriately, Poincare invariance holds. The analysis is performed in both the commutative as well as noncommutative descriptions and a compatibility between the two is also established.

Knots, tangles and braid actions
Creators: name: Watson, Liam Thomas
Publisher: name: University of British Columbia
Year: 2009

description: Recent work of Eliahou, Kauffmann and Thistlethwaite suggests the use of braid actions to alter a link diagram without changing the Jones polynomial. This technique produces non-trivial links (of two or more components) having the same Jones polynomial as the unlink. In this paper, examples of distinct knots that can not be distinguished by the Jones polynomial are constructed by way of braid actions. Moreover, it is shown in general that pairs of knots obtained in this way are not Conway mutants, hence this technique provides new perspective on the Jones polynomial, with a view to an important (and unanswered) question: Does the Jones polynomial detect the unknot?

description: AbstractCreating value for stakeholders is a crucial goal for many organisations, including Islamic banking institutions. Value-Based Intermediation (VBI) is the most recent initiative issued by Bank Negara Malaysia to improve the role of Islamic banks towards achieving innovation, transparency, financial stability and sustainable growth. This paper aims to shed light on the VBI disclosure practices among Islamic banks in Malaysia and analyse the use of integrating reporting (IR) framework to communicate VBI information to stakeholders. The content analysis has been conducted on the annual reports of 16 Islamic banks in Malaysia to collect the data for the years 2017 and 2018. The findings showed that the IR framework, including business model, could present the VBI disclosures in a concise, holistic and efficient way in comparison to conventional reporting approaches. Furthermore, there is an increase in the implementation of VBI and IR among Islamic banks. Almost 69% of all Islamic banks have VBI disclosures in their 2018 annual reports. Nearly half of these banks used IR to report their VBI disclosures. This study contributes to the literature by providing critical insights to management, analysts, investors and policymakers in improving the VBI disclosure through IR as a new practice in the Islamic banking industry.

description: The volatility of agricultural markets has increased remarkably in recent years. In spite of this, the way in which supply chain actors perceive market volatility has only rarely been analyzed. This paper seeks to close this research gap by presenting empirical findings about how the volatility of agricultural markets is perceived, how increasing market volatilities are being explained, and what adaptations to the volatile external environments are being suggested. Based on a large-scale media analysis, we have identified perceptions, which vary greatly over time, especially with regard to the perception of the threats and opportunities volatility creates for farms and firms and the most frequently identified reasons for volatile prices
Dynamics of an inverted cantilever plate at moderate angle of attack

description: The dynamics of a cantilever plate clamped at its trailing edge and placed at a moderate angle ($α\leq 30^{\circ}$) to a uniform flow are investigated experimentally and numerically, and a large experimental data set is provided. The dynamics are shown to differ significantly from the zero-angle-of-attack case, commonly called the inverted-flag configuration. Four distinct dynamical regimes arise at finite angles: a small oscillation around a small-deflection equilibrium (deformed regime), a small-amplitude flapping motion, a large-amplitude flapping motion and a small oscillation around a large-deflection equilibrium (deflected regime). The small-amplitude flapping motion appears gradually as the flow speed is increased and is consistent with a limit-cycle oscillation caused by the quasi-steady fluid forcing. The large-amplitude flapping motion is observed to appear at a constant critical flow speed that is independent of angle of attack. Its characteristics match those of the large-amplitude vortex-induced vibration present at zero angle of attack. The flow speed at which the plate enters the deflected regime decreases linearly as the angle of attack is increased, causing the flapping motion to disappear for angles of attack greater than $α\approx 28^{\circ}$. Finally, the effect of aspect ratio on the plate dynamics is considered, with reduced aspect ratio plates being shown to lack sharp distinctions between regimes.
