description: By numerically solving models with competing superconducting and antiferromagnetic orders, we study the magnetic field dependence of the antiferromagnetic moment in both the weak and strong field regimes. Through a omparison with the neutron scattering results of Kang et al and Matsuura et al.on $Nd_{1.85}Ce_{0.15}CuO_4$, we conclude that this system is close to a SO(5) symmetric critical point. We also make a quantitative prediction on increasing the upper critical field $B_{c2}$ and the superconducting transition temperature $T_c$ by applying an in-plane magnetic field.

description: We determine the work functions of the iron arsenic compounds $A$Fe$_2$As$_2$ ($A=\mathrm{Ca, Ba, Cs}$) using photoemission spectroscopy to be 2.7 eV for CaFe$_2$As$_2$, 1.8 eV for BaFe$_2$As$_2$, and 1.3 eV for CsFe$_2$As$_2$. The work functions of these 122 iron-based superconductors track those of the elementary metal $A$ but are substantially smaller. The most likely explanation of this observation is that the cleaving surface exposes only half an $A$-layer. The low work function and good photoemission cross section of BaFe$_2$As$_2$ and CsFe$_2$As$_2$ enable photoemission even from a common white LED light.

description: Since February 2018 the online tool TOTEM (Tool to Optimise the Total Environmental impact of Materials) can be used by building professionals to acquire an insight into
the Environmental Performance of Materials used in Buildings and Building Elements (in Dutch: MMG: Milieugerelateerde Materiaalprestatie van Gebouw(element)en). With TOTEM it is possible to assess and communicate about the environmental performance of buildings and elements in a uniform and neutral way, adapted specifically to the Belgian building context. This publication offers an open and transparent presentation of the MMG assessment framework, the underlying methodology of TOTEM, and is an updated version of the publication dd March 2013. Although the presented building materials methodology is far from final, it
is a dynamic assessment framework (and web tool) that will be fine-tuned and extended in the future. In that context, this publication should be perceived as a communication tool to facilitate the dialogue with stakeholders (architects, material
producers, building owners) in the future.
title: Motion of Particles in Complex Flows
Creators: name: Bezuglyy, Vladyslav
Publisher: name: The Open University
Year: 2009

description: This thesis covers various aspects of motion of small rigid particles in complex flows. It is in two parts. Part I is concerned with motion of small spherical particles. We study extensions of two classical models for diffusion of a particle driven by random forces, namely the Ornstein-Uhlenbeck process and Chandrasekhar-Rosenbluth model. We show that both models exhibit similar scaling of the diffusion matrix, leading to the same short-time asymptotic dynamics characterized by anomalous diffusion of the momentum and ballistic diffusion of the displacement. We discuss a generalization of the Kramers model describing an overdamped particle in an external potential driven by random forces. We analyze the stationary probability density of the position in the limit when the external forcing is strong and show that the density yields a non-zero probability flux for the motion in a periodic potential with a broken reflection symmetry. We explain quantitatively an abrupt increase of the collision rate of inertial particles suspended in a flow, as the intensity of turbulence I passes a threshold. We argue that the collision rate exhibits an activated behaviour containing a factor exp(-const/I) due to the formation of fold caustics in their velocity field. Part II is concerned with patterns formed by small non-spherical, axisymmetric particles advected in a flow. Numerical simulations suggest that the direction field of the particles exhibits topological singularities of the same type as those seen in fingerprints. An exact solution of the equation of motion indicates that the direction field is non-singular, but we give a theoretical explanation arguing that the singularities are approached in an asymptotic sense. We introduce the order parameter vector characterizing the alignment of particles. We show that the order parameter field also exhibits singularities and describe their normal forms. The order parameter is related to the reflection of light by a rheoscopic fluid illuminated by three coloured light sources. We report on the results of a simple experiment supporting our theoretical findings.

description: We present new measurements of the Sunyaev-Zel'dovich (SZ) effect from clusters of galaxies using the Sunyaev-Zel'dovich Infrared Experiment (SuZIE II). We combine these new measurements with previous cluster observations with the SuZIE instrument to form a sample of 15 clusters of galaxies. For this sample we calculate the central Comptonization, y, and the integrated SZ flux decrement, S, for each of our clusters. We find that the integrated SZ flux is a more robust observable derived from our measurements than the central Comptonization due to inadequacies in the spatial modelling of the intra-cluster gas with a standard Beta model. This is highlighted by comparing our central Comptonization results with values calculated from measurements using the BIMA and OVRO interferometers. On average, the SuZIE calculated central Comptonizations are approximately 60% higher in the cooling flow clusters than the interferometric values, compared to only approximately 12% higher in the non-cooling flow clusters. We believe this discrepancy to be in large part due to the spatial modelling of the intra-cluster gas. From our cluster sample we construct y-T and S-T scaling relations. The y-T scaling relation is inconsistent with what we would expect for self-similar clusters; however this result is questionable because of the large systematic uncertainty in the central Comptonization. The S-T scaling relation has a slope and redshift evolution consistent with what we expect for self-similar clusters with a characteristic density that scales with the mean density of the universe. We rule out zero redshift evolution of the S-T relation at 90% confidence.

description: Low productivity in agriculture is mainly due to the inability of the farmers to exploit the available technologies fully, resulting in lower efficiencies of production. This study employed a Cobb-Douglas stochastic frontier production function to measure the level of technical efficiency and its determinants in snail production in Ngor Okpala LGA of Imo state, Nigeria. Primary data was generated through the use of closed and open ended structured questionnaire in line with the objectives of the study. Respondents were selected through a systematic random sampling procedure. 40 snail farmers were selected, from whom socioeconomic and input-output data were obtained using the cost-route approach. The parameters of the stochastic frontier production function were estimated using the maximum likelihood method. The study found farm size, labour and feed to be positively and significantly related to output at 5% level of significance. Socioeconomic factors influencing technical efficiency directly were farming experience and credit access at 5% level of significance. Age and stock size were negatively and significantly related to technical efficiency at 5% level of significance. Result of returns to scale analysis showed that snail production is at the stage of increasing returns to scale. We recommend that Snail farmers should have greater access to formal credit facilities from lending institutions in order to expand and improve their production. They should be encouraged to form stronger co-operative societies so as to expand their scope of production and marketing. Farmers are advised to grow most of the green feed stuffs the snails eat to save costs.
Mechanism of d_{x^2-y^2}-wave superconductivity based on doped hole induced spin texture in high T_c cuprates

description: A mechanism of d_{x^2-y^2}-wave superconductivity is proposed for the high-T_c cuprates based on a spin texture with non-zero topological density induced by doped holes through Zhang-Rice singlet formation. The pairing interaction arises from the magnetic Lorentz force like interaction between the holes and the spin textures. The stability of the pairing state against the vortex-vortex interaction and the Coulomb repulsion is examined. The mechanism suggests appearance of a p-wave pairing component by introducing anisotropy in the CuO_2 plane.

description: Phase diagrams of the two-dimensional one-band t-t' Hubbard model are obtained within the two-patch and the temperature-cutoff many-patch renormalization group approach. At small t' and at van Hove band fillings antiferromagnetism dominates, while with increasing t' or changing filling antiferromagnetism is replaced by d-wave superconductivity. Near t'=t/2 and close to van Hove band fillings the system is unstable towards ferromagnetism. Away from van Hove band fillings this ferromagnetic instability is replaced by a region with dominating triplet p-wave superconducting correlations. The results of the renormalization-group approach are compared with the mean-field results and the results of the T-matrix approximation.

title: The Formation and Evolution of Cataclysmic Variables
Creators: name: Davis, Philip
Publisher: name: The Open University
Year: 2009

description: White dwarf-main sequence star (WD+MS) binaries allows us to investigate two major, poorly understood, paradigms of binary evolution. Firstly, the disrupted magnetic braking (DMB) model; a widely cited explanation for the paucity of observed cataclysmic variables (CVs) with orbital periods of between about 2 and 3 hours (coined the period gap). Secondly, common envelope (CE) evolution, which is thought to be a major formation mechanism of semi-detached, compact binaries. Despite the ubiquity of these models in the literature, they have yet to be comprehensively tested with observations. To test the former paradigm, we exploit the model’s main prediction: the existence of detached WD+MS binaries within the period gap that were CVs but ceased mass transfer as a result of DMB (‘detached CVs’; dCVs). For a range of models describing the CE phase and magnetic braking, we employ population synthesis techniques to calculate the present day population of dCVs and detached WD+MS that have formed from a CE phase (post-common envelope binaries; PCEBs). We find that dCVs outnumber PCEBs with late spectral-type secondary stars within the period gap by a factor of between 4 and 13. This excess manifests as a prominent peak within the period gap of the combined PCEB and dCV orbital period distribution. If this feature is detected in the observed WD+MS orbital period distribution, it would strongly corroborate the DMB model. Our comprehensive analysis between the theoretical and observed PCEB populations shows that an αcE >0.1 and an initial mass ratio distribution favouring small mass ratios, q < 1, best reproduces the observed PCEB distribution, and the observed local space density. Finally, we reconstruct the CE phase for the observed PCEBs and investigate any dependence of αcE on the secondary mass and the orbital period of the PCEB. Indeed, this may shed light into the CE ejection mechanism.

description: We investigate the possibility of charge carrier localization in magnetic semiconductors due to the presence of a highly inhomogeneous external magnetic field. As an example, we study in detail the properties of a magnetic semiconductor-permalloy disk hybrid system. We find that the giant Zeeman respose of the magnetic semiconductor in conjuction with the highly non-uniform magnetic field created by the vortex state of a permalloy disk can lead to Zeeman localized states at the interface of the two materials. These trapped state are chiral, with chirality controlled by the orientation of the core magnetization of the permalloy disk. We calculate the energy spectrum and the eigenstates of these Zeeman localized states, and discuss their experimental signatures in spectroscopic probes.

Stochastic thermodynamics of relativistic Brownian motion

Year: 2020
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Physical scenarios that require a relativistic treatment are ubiquitous in nature, ranging from cosmological objects to charge carriers in Dirac materials. Interestingly all of these situations have in common that the systems typically operate very far from thermal equilibrium. Therefore, if and how the framework of stochastic thermodynamics applies at relativistic energies is a salient question. In the present work we generalize the notions of stochastic heat and work for the relativistic Langevin equation and derive the fluctuation theorems without and with feedback. For processes with feedback we consider the ramifications of the lack of simultaneity of events in the inertial frames of observer and Brownian particles, and we argue that the framework of absolute irreversibility is instrumental to avoid acausal considerations. The analysis is concluded with a few remarks on potential experimental applications in graphene.

description: Evaluation of the effectiveness of extension delivery channels used in disseminating agricultural practices/technologies to farmers in the South-western zone of Nigeria was the focus of this study. Emphasis was placed on identification of various extension delivery channels used by various agencies and institutions, and the effectiveness of each of the channels in imparting knowledge, skill and attitude to farmers. Structured, pretested and validated interview schedule were completed by 600 respondents selected through multi-stage random sampling techniques in Ogun and Osun States. Descriptive statistical techniques like frequency counts, mean, weighted mean score and percentages were used to analyze the data. Correlation was used to determine the relationship between the variables investigated in the study. The study shows positive and significant correlation between the effectiveness of extension delivery channels and level of education (r =0.29), income (r = 0.28), membership of association (r = 0.26), and farming experience (r = 0.21). Also, farmers’ perceptions of the use of extension delivery channel in the study areas ranked very low showing the ineffectiveness of the delivery channels. The most effective extension delivery channels are other farmers (8.8), friends/relatives (8.54), radio (8.51) and extension agents (8.5). This paper therefore recommends that extension should play a more active role in helping farmers to get organized into functional organizations, including commodity groups, credit societies, cooperatives, and other types of farmer associations while using combination of different delivery channels to disseminate extension technologies to farmers. Media organizations particularly the public-owned should devout a certain amount of air time for agricultural extension (radio and TV) programmes.

description: Polycrystalline La1-xPbxMnO3+-y (x = 0.3, 0.35, 0.4) solid solutions were prepared by solid state reaction method and their magnetic properties have been investigated. Rietveld refinement of X-ray powder diffraction patterns showed that all samples are single phase and crystallized with the rhombohedral structure in the R-3c space group. A second order paramagnetic to ferromagnetic phase transition was observed for all materials. The Griffiths phase (GP), identified from the temperature dependence of the inverse susceptibility, was suppressed by increasing magnetic field and showed a significant dependence on A-site chemical substitution. The critical behaviour of the compounds was investigated near to their Curie temperatures, using intrinsic magnetic field data. The critical exponents (\b{eta}, γ and δ) are close to the mean-field approximation values for all three compounds. The observed mean-field like behaviour is a consequence of the GP and the formation of ferromagnetic clusters. Long-range ferromagnetic order is established as the result of long-range interactions between ferromagnetic clusters. The magnetocaloric effect was studied in terms of the isothermal entropy change. Our study shows that the material with the lowest chemical substitution (x = 0.3) has the highest potential (among the three compounds) as magnetic refrigerant, owing to its higher relative cooling power (258 J/kg at 5 T field) and a magnetic phase transition near room temperature.

description: An interplanetary (IP) shock wave was recorded crossing the Magnetospheric Multiscale (MMS) constellation on 2018 January 8. Plasma measurements upstream of the shock indicate efficient proton acceleration in the IP shock ramp: 2-7 keV protons are observed upstream for about three minutes (~8000 km) ahead of the IP shock ramp, outrunning the upstream waves. The differential energy flux (DEF) of 2-7 keV protons decays slowly with distance from the ramp towards the upstream region (dropping by about half within 8 Earth radii from the ramp) and is lessened by a factor of about four in the downstream compared to the ramp (within a distance comparable to the gyroradius of ~keV protons). Comparison with test-particle simulations has confirmed that the mechanism accelerating the solar wind protons and injecting them upstream is classical shock drift acceleration. This example of observed proton acceleration by a low-Mach, quasi-perpendicular shock may be applicable to astrophysical contexts, such as supernova remnants or the acceleration of cosmic rays.

In particular, the extremal cross-sectional areas, and the appropriate cyclotron masses are calculated. We also find the phase of the quantum oscillations associated with the electron orbits near the crossing point. The analysis of all these quantities is carried out both without and with consideration of the spin-orbit interaction. To illustrate the obtained results, we apply them to ZrSiS in which the crossing of the nodal lines occurs.

description: Large N topological string dualities have led to a class of proposed open/closed dualities for superstrings. In the topological string context, the worldsheet derivation of these dualities has already been given. In this paper we take the first step in deriving the full ten-dimensional superstring dualities by showing how the dualities arise on the superstring worldsheet at the level of F terms. As part of this derivation, we show for F-term computations that the hybrid formalism for the superstring is equivalent to a $\hat c=5$ topological string in ten-dimensional spacetime. Using the $\hat c=5$ description, we then show that the D brane boundary state for the ten-dimensional open superstring naturally emerges on the worldsheet of the closed superstring dual.

description: To identify the preferences and perceptions of migraine patients for acute and preventive treatment options and to investigate which treatment outcomes are the most important. The authors performed a choice-format survey in a cohort of migraine patients from Greece and Cyprus. A self-administered questionnaire developed in collaboration with the Greek Society of Migraine Patients was used. Questionnaires were collected from 617 migraine patients. Efficacy was preferred over safety as the single most important parameter, both in acute and preventive treatment. When analyzing single outcomes, patients prioritized a complete pain remission at 1-hour post-dose for acute therapies. Regarding migraine prevention, a 75% reduction in frequency, intensity of pain, accompanying symptoms and acute medication intake were considered as most important. Conversely, outcomes routinely used in clinical trials, namely complete or partial pain remission at 2-hours post-dose for acute treatment and 50% or 30% reduction in migraine frequency for prevention, were not deemed particularly relevant. Tablet formulation was mostly preferred, both in acute and preventive treatment. Listening to patients’ needs may add a piece of the puzzle that is generally missing in clinical practice and often explains the lack of adherence in both acute and preventative anti-migraine therapies.
A sensitivity study of the primary correlators used to characterize chiral-magnetically-driven charge separation

description: A Multi-Phase Transport (AMPT) model is used to study the detection sensitivity of two of the primary correlators -- $Δγ$ and $R_{Ψ_{2}}$ -- employed to characterize charge separation induced by the Chiral Magnetic Effect (CME). The study, performed relative to several event planes for different input "CME signals", indicates a detection threshold for the fraction $f_{\rm CME}=Δγ_{\rm CME}/Δγ$, which renders the $Δγ$-correlator insensitive to values of the Fourier dipole coefficient $a_1 \lesssim 2.5\%$, that is larger than the purported signal(signal difference) for ion-ion(isobaric) collisions. By contrast, the $R_{Ψ_{2}}$ correlator indicates concave-shaped distributions with inverse widths ($\mathrm{σ^{-1}_{R_{Ψ_2}}}$) that are linearly proportional to $a_1$, and independent of the character of the event plane used for their extraction. The sensitivity of the $R_{Ψ_{2}}$ correlator to minimal CME-driven charge separation in the presence of realistic backgrounds, could aid better characterization of the CME in heavy-ion collisions.

description: This article uses financial information from Iowa farms to explore the relationship between ARC-CO payments and farm income, profitability, liquidity, solvency, and size. Rather than acting as a safety net for Iowa farmers, ARC-CO payments can be more accurately characterized as decoupled support.
Memory effect in the charge transport in strongly disordered antimony films

description: We study conductivity of strongly disordered amorphous antimony films under high bias voltages. We observe non-linear current-voltage characteristic, where the conductivity value at zero bias is one of two distinct values, being determined by the sign of previously applied voltage. Relaxation curves demonstrate high stability of these conductivity values on a large timescale. Investigations of the antimony film structure allows to determine the percolation character of electron transport in strongly disordered films. We connect the memory effect in conductivity with modification of the percolation pattern due to recharging of some film regions at high bias voltages.

description: Clubs are voluntarily-shared but excludable facilities prone to congestion. Examples include tolled trunk road, the telephone system and "gentlemen's" clubs. Despite 25 years of development, the clubs literature does not contain a satisfactory treatment of the membership of the sharing group which allows for differences in income and/or tastes and for agents' self-selection to club membership or non-membership. This paper provides such a treatment and applies it to profit-maximising and revenue-constrained welfare-maximising clubs and to the analysis of the social organisation of a facility of fixed size.

description: The basis elements spanning the Sato Grassmannian element corresponding to the KP $τ$-function that serves as generating function for rationally weighted Hurwitz numbers are shown to be Meijer $G$-functions. Using their Mellin-Barnes integral representation the $τ$-function, evaluated at the trace invariants of an externally coupled matrix, is expressed as a matrix integral. Using the Mellin-Barnes integral transform of an infinite product of $Γ$ functions, a similar matrix integral representation is given for the KP $τ$-function that serves as generating function for quantum weighted Hurwitz numbers.

Possible methods for the determination of the $P$-parity of the $Θ^+$-pentaquark in NN-collisions

description: We present two possibilities to determine the P-parity of the pentaquark $Θ^+$, in a model independent way, via the measurement of polarization observables in $p+p\to Θ^+ +Σ^+$, or $n+p\to Θ^+ +Λ^0$, in the near threshold region. Besides the measurement of the spin correlation coefficient, $A_{xx}=A_{yy}$, (in collisions of transversally polarized nucleons), the coefficient $D_{xx}$ of polarization transfer from the initial proton to the final $ Σ^+(Λ^0)$ hyperon is also unambiguously related to the $Θ^+$ parity.

A slow-down time-transformed symplectic integrator for solving the few-body problem

description: An accurate and efficient method dealing with the few-body dynamics is important for simulating collisional N-body systems like star clusters and to follow the formation and evolution of compact binaries. We describe such a method which combines the time-transformed explicit symplectic integrator (Preto & Tremaine 1999; Mikkola & Tanikawa 1999) and the slow-down method (Mikkola & Aarseth 1996). The former conserves the Hamiltonian and the angular momentum for a long-term evolution, while the latter significantly reduces the computational cost for a weakly perturbed binary. In this work, the Hamilton equations of this algorithm are analyzed in detail. We mathematically and numerically show that it can correctly reproduce the secular evolution like the orbit averaged method and also well conserve the angular momentum. For a weakly perturbed binary, the method is possible to provide a few order of magnitude faster performance than the classical algorithm. A publicly available code written in the c++ language, SDAR, is available on GitHub (https://github.com/lwang-astro/SDAR). It can be used either as a stand alone tool or a library to be plugged in other $N$-body codes. The high precision of the floating point to 62 digits is also supported.

Demand and Price Analysis

description: A two-sector model of imperfect competition with intermediate goods is developed and analysed by numerical simulation. It is shown how an objective notion of demand can be derived and employed in three concepts of equilibrium that differ in the possibilities for price-discrimination and collusion. The results indicate that there may be excessive use of labour relative to produced input in production, that price discrimination reduces both welfare and profits and that collusion between firms is beneficial to both the firms and the consumer. In addition, collusion may result in produced inputs being sold at a price less than marginal cost.
Lattice QCD Evidence for Exotic Tetraquark Resonance

description: We study the manifestly exotic tetraquark D$_{\rm s0}^{++}(cu\bar s \bar d)$ and the scalar tetraquark $f_0(ud \bar u \bar d)$ in SU(3)$_c$ anisotropic quenched lattice QCD with the $O(a)$-improved Wilson (clover) fermion with various quark masses including the idealized SU(4)$_f$ case. For $f_0(ud\bar u \bar d)$ etc., we only consider connected diagrams at the quenched level, i.e., the tetraquark $f_0(ud\bar u\bar d)$ is identical with D$_{\rm s0}^{++} (cu\bar s \bar d)$ in the idealized SU(4)$_f$ case. First, for comparison, we study the lowest $q\bar q$ scalar meson, and find that it has a large mass of about 1.37GeV after chiral extrapolation, which corresponds to $f_0(1370)$. Second, we investigate the lowest 4Q state in the spatial periodic boundary condition, and find that it is just a scattering state of two pseudoscalar mesons, as is expected. Third, to extract spatially-localized 4Q resonances, we use the Hybrid Boundary Condition (HBC) method, where anti-periodic and periodic boundary conditions are imposed on quarks ($c$,$u$) and antiquarks ($\bar s$,$\bar d$), respectively. By applying the HBC on a finite-volume lattice, the threshold of the two-meson scattering state is raised up, while the mass of a compact 4Q resonance is almost unchanged. In HBC, we find a nontrivial 4Q resonance state about 100 MeV below the two-meson threshold in some quark-mass region. Its chiral behavior largely differs from a two-meson scattering state. The scalar tetraquark $f_0(ud\bar u\bar d)$ is found to have the mass of about 1.1GeV after chiral extrapolation, and seems to correspond to $f_0(980)$. Then, the manifestly exotic tetraquark D$_{\rm s0}^{++}(cu\bar s \bar d)$ would exist around 1GeV in the idealized SU(4)$_f$ chiral limit. Finally, MEM analysis is applied to obtain the spectral function of the 4Q system.
