description: The spontaneous self-consistent generation of axial current and corresponding dipole-like magnetic field in a planar electron-positron system similar to graphene and related hetero-structures doped by charged impurity with charge $Z$ is explored. It is shown that this effect takes place for $Z \geq Z^{\ast}$ with $Z^{\ast}$ being a peculiar analogue of the Curie point in ferromagnetics. The properties of induced ferromagnetic state are studied in detail. It is shown also that the arising this way magnetic dipole leads to a significant decrease of the total Casimir (vacuum) energy of the system, which in turn provides its spontaneous generation above the "Curie point" $Z \geq Z^{\ast}$.

description: We report on a peculiar X-ray binary pulsar IKT1 = RXJ0047.3-7312 observed with XMM-Newton in Oct. 2000. The X-ray spectrum is described by a two-component spectrum. The hard component has a broken power-law with respective photon indices of 0.2 and 1.8, below and above the break energy at 5.8 keV. The soft component can be modeled by a blackbody of kT = 0.6 keV. The X-ray flux shows a gradual decrease and periodic variations of about 4000 s. The averaged flux in 0.7-10.0 keV is 2.9x10^-12 ergs/cm^2/s, which is ~10 times brighter than that in a ROSAT observation in Nov. 1999. In addition to the 4000-s variation, we found coherent pulsations of 263 +/- 1 s. These discoveries strengthen the Be/X-ray binary scenario proposed by the ROSAT and ASCA observations on this source, and confirm that most of the hard sources in the Small Magellanic Cloud are X-ray binary pulsars. A peculiar property of this XBP is that the coherent pulsations are found only in the soft component, and the folded light curve shows a flat top shape with a sharp dip. We discuss the nature of this XBP focusing on the peculiar soft component.

description: Indonesia is a South-East Asian nation of about 255 million people. Indonesia isa lower-middle-income country with a gross domestic product (GDP) of aboutUS$ 3927 per capita per year. Following the decentralization of the national healthsystem, the health-care service and management system is organized into threeadministrative levels: central, provincial, and district.This Country Profile was updated in 2019 to provide a comprehensive and mostrecent overview of the human resources for health (HRH) situation in Indonesiato be used in the national development of the HRH. The policy and strategy aredesigned to guide government, partners and other stakeholders in prioritizing,developing and implementing activities for improving HRH.In accordance with the Long-Term National Development Plan (RPJPN) 2005-2025,the medium-term development target of 2020-2024 is to create fair, prosperous,dignified, economically independent through accelerating development in variousfields including health sector. The public health agenda led by the Ministry ofHealth put priority on health provision, community empowerment on healthinitiatives, drugs and health equipment availability, human resources for health(HRH), research and development, health financing, and health information system.In the Strategic Plan document of the Ministry of Health, HRH development is oneof priorities in health development. It includes several strategic activities such asHRH planning and management, pre-service and in-service trainings, HRH qualityincluding registration and certification and other management and technicalsupport for HRH development program.Along with most social sectors, the health sector is a decentralized public affairwhich delegates responsibilities especially on health service delivery from thecentral to the sub national (province) and the local level (district). This has hadimplications on human resource planning and management which include the needfor accurate and timely data and information on HRH. It has become clear thatthere is an urgent need to strengthen national health information system. Specialattention is required at both regional and national levels to create an up-to-dateHRH information system.

description: The literature about export assistance divides such programs according to whether they apply to each unit of a particular commodity exported by the subsidizing country or whether they are targeted toward specific markets. These global and targeted export assistance programs are further distinguished by whether payment of the subsidies is made in cash or in kind. Traditional theory determines global cash export assistance to be welfare reducing for the exporter, while the effect of global export assistance paid in kind depends on the cost of in kind subsidies. Global cash assistance may become a rational instrument for capturing of greater market shares in the future or for satisfying influential political interest groups. Targeted assistance offers potential benefits to the exporting country by directing subsidies toward markets with greater income and substitution effects, leading to greater price responsiveness. However, empirical studies find that targeted assistance offers only small benefits in expanding exports and causes substantial disruptions in trade flows.

We design the shifted knots of Bernstein-Kantorovich operators generated by the basic q-calculus. More precisely, we study the convergence properties of our new operators in the space of continuous functions and Lebesgue space. We obtain the degree of convergence with the help of modulus of continuity and integral modulus of continuity. Furthermore, we establish the quantitative estimates of Voronovskaja-type.

description: In this study, the sensitivity of future lepton colliders to WIMP dark matter is evaluated assuming WIMP pair production accompanied by a photon from initial state radiation, through which the process can be identified. A full detector simulation for the International Large Detector (ILD) concept at the International Linear Collider (ILC) is performed for a \com energy of 500\,GeV. Energy scales of up to $3$\,TeV can be tested for different effective operators for WIMP masses almost up to half the \com energy. The sensitivity benefits from the polarised beams, which can reduce the main SM background from neutrino pair production substantially. In addition, systematic uncertainties are shown to be significantly reduced by combining data with several different polarisation configurations. In comparison to a previous study, the reconstruction of the forward detectors has been improved and the systematic uncertainties are fully treated. The results are also extrapolated to other \com energies, luminosities and beam polarisations. This allows to provide results for the full ILC programme, i.e.\ from 250\,GeV to 1\,TeV, as well as to give approximate results for other planned lepton colliders.

Subdomain solution decomposition method for nonstationary problems

description: The reduction of computational costs in the numerical solution of nonstationary problems is achieved through splitting schemes. In this case, solving a set of less computationally complex problems provides the transition to a new level in time. The traditional construction approach of splitting schemes is based on an additive representation of the problem operator(s) and uses explicit-implicit approximations for individual terms. Recently (Y. Efendiev, P.N. Vabishchevich. Splitting methods for solution decomposition in nonstationary problems. \textit{Applied Mathematics and Computation}. \textbf{397}, 125785, 2021), a new class of methods of approximate solution of nonstationary problems has been introduced based on decomposition not of operators but of the solution itself. This new approach with subdomain solution selection is used in this paper to construct domain decomposition schemes. The boundary value problem for a second-order parabolic equation in a rectangle with a difference approximation in space is typical. Two and three-level schemes for decomposition of the domain with and without overlapping subdomains are investigated. Our numerical experiments complement the theoretical results.

description: The statistical expectation values of the temperature fluctuations of the Cosmic Microwave Background (CMB) are assumed to be preserved under rotations of the sky. We investigate the Statistical Isotropy (SI) of the CMB anisotropy maps recently measured by the Wilkinson Microwave Anisotropy Probe (WMAP) using Bipolar Power Spectrum (BiPS) proposed in [Hajian & Souradeep 2003]. The method can probe specific regions in multipole space using appropriate window functions. The BiPS is estimated for full sky CMB anisotropy maps based on the first year WMAP data using a range of window functions. The BiPS spectra computed for both full sky maps for all our window functions are consistent with zero, roughly within $2 σ$. The null BiPS results may be interpreted as an absence of strong violation of statistical isotropy in the first-year WMAP data on angular scales larger than that corresponding to $l\sim60$. However, pending a careful direct comparison, our results do not necessarily conflict with the specific SI related anomalies reported using other statistical tests.

title: The Genesis of Sulphides in the Shetland Ophiolite
Creators: name: Maynard, Jonathan
Publisher: name: The Open University
Year: 1994

description: This thesis describes the sulphide, arsenide and antimonide mineral assemblages and stable isotope geochemistry of each magmatic and alteration lithology of the Shetland ophiolite complex and identifies a new assemblage of Pd and Pt-bearing nickel antimonides.

 The assemblages have been characterized as follows. Cumulate rocks typically contain a variety of Ni- Fe- and Cu-bearing opaque (biases including relict sulphides, native metals, arsenides and antimonides. The sulphide assemblages show a strong correlation with the host silicate lithology. Dunite pods in harzburgite and cumulate dunites contain the assemblage pentlandite-heazlewoodite-millerite-godlevskite-chalcopyrite-chalcocite-native Cu ± awaruite ± troilite ± orcelite ± breithauptite/Ni- Cu antimonide. Cumulate wehrlites and pyroxenites contain pentlandite-pyrrhotite-pyrite-chalcopyrite-bornite-chalcocite-native copper ± orcellite and maucherite. Gabbros and dolerite dykes contain pyrrhotite-pyrite-marcasite-chalcopyrite ± pentlandite. These assemblages developed by the alteration of precursory magmatic sulphides.

 A technique has been developed and used to measure whole-rock δ34S values to a precision of ±0.5‰. δ34S measurements suggest an igneous source for sulphur in sulphide-bearing dunite pods (+4.3‰), cumulate dunites (+3.1‰), cumulate pyroxenites (+2.9‰) and gabbros and dolerite dykes (+4.5‰). Talc-carbonate altered rocks (+0.9‰) from close to the basal thrust may have derived a portion of sulphur from the underlying metasediments (-4.2‰). Sub-massive pyrite mineralization from high-level gabbros (+9 to +14‰) requires a contribution of hydrothermal sulphur, this has been corroborated by He isotope analysis. Hydrogen and oxygen isotope analyses have shown that serpentine minerals in dunites have exchanged water with meteoric fluids, whereas pyroxenites and gabbros retain a hydrothermal seawater signature.

 A diverse assemblage of PGM are known to be intergrown or intimately associated with the base metal suphides and nickel arsenides in dunite pods in harzburgite and cumulate dunites. A new assemblage of Pd ± Pt-bearing Ni and Ni- Cu antimonides are associated with these PGM and disseminated Ni- Fe-sulphides. The paragenesis of these antimonides is described for a sulphide-bearing dunite pod from the PGE-rich Cliff locality and from a PGE-enriched mineralized horizon in cumulate dunites. At both localities the paragenesis of the antimonides is closely linked to the alteration of the coexisting sulphide assemblage.

description: We study the superconducting order parameter near a surface with the Bogoliubov-de Gennes formalism. For definiteness we use the attractive Hubbard model. Near a surface, the order parameter and the density distribution exhibit ``Friedel-like'' oscillations. Although the local density of states is quite different from that in the bulk, the energy gap in the spectrum on a surface is almost the same as the bulk value. In the low-density limit, however, the energy gap tends to vanish on a surface.

description: In this paper I look at how gender segregation in writing classes could increase the amount of on-task behaviour and voluntary sharing of work. Following a review of recent research in the fields of biological gender differences, single-gender instruction and gender and writing, a study of a grade seven writing class is described. For eleven weeks, I observed both mixed and single-gender groups during a variety of writing activities. Using observation, tally charts and anonymous surveys, I amassed qualitative and quantitative data. These are analyzed to show that improvement could be seen in the areas of voluntary sharing and less off-task behaviour. A discussion and implementations are included.

description: The combination of the exciting properties of graphene with those of monolayer tungsten disulfide (WS2) makes this heterostack of great interest for electronic, optoelectronic and spintronic applications. The scalable synthesis of graphene/WS2 heterostructures on technologically attractive substrates like SiO2 would greatly facilitate the implementation of novel two-dimensional (2D) devices. In this work, we report the direct growth of monolayer WS2 via chemical vapor deposition (CVD) on single-crystal graphene arrays on SiO2. Remarkably, spectroscopic and microscopic characterization reveals that WS2 grows only on top of the graphene crystals so that the vertical heterostack is selectively obtained in a bottom-up fashion. Spectroscopic characterization indicates that, after WS2 synthesis, graphene undergoes compressive strain and hole doping. Tailored experiments show that such hole doping is caused by the modification of the SiO2 stoichiometry at the graphene/SiO2 interface during the WS2 growth. Electrical transport measurements reveal that the heterostructure behaves like an electron-blocking layer at large positive gate voltage, which makes it a suitable candidate for the development of unipolar optoelectronic components.

description: Personalized medicine marks a significant shift from the traditional "one-size-fits-all" model, using biochemistry and genomics to treat patients based on their unique biological makeup. This approach transforms medicine into a tool that reflects individual molecular complexity, moving beyond technical applications to bridge medical philosophy and clinical practice. By decoding the human genome, we reveal both shared ancestry and distinct personal traits. Technologies like Next-Generation Sequencing (NGS) redefine diseases as interconnected systems rather than isolated issues.

description: Understanding the long-term evolution of hierarchical triple systems is challenging due to its inherent chaotic nature, and it requires computationally expensive simulations. Here we propose a convolutional neural network model to predict the stability of hierarchical triples by looking at their evolution during the first $5 \times 10^5$ inner binary orbits. We employ the regularized few-body code TSUNAMI to simulate $5\times 10^6$ hierarchical triples, from which we generate a large training and test dataset. We develop twelve different network configurations that use different combinations of the triples' orbital elements and compare their performances. Our best model uses 6 time-series, namely, the semimajor axes ratio, the inner and outer eccentricities, the mutual inclination and the arguments of pericenter. This model achieves an area under the curve of over $95\%$ and informs of the relevant parameters to study triple systems stability. All trained models are made publicly available, allowing to predict the stability of hierarchical triple systems $200$ times faster than pure $N$-body methods.

description: We study from first-principles the structural and electronic properties of head-to-head (HH) and tail-to-tail (TT) 180$^\circ$ domain walls in isolated free-standing PbTiO$_{3}$ slabs. For sufficiently thick domains ($n$ = 16 unit cells of PbTiO$_{3}$), a transfer of charge from the free surfaces to the domain walls to form localized electron (in the HH) and hole (in the TT) gases in order to screen the bound polarization charges is observed. The electrostatic driving force behind this electronic reconstruction is clearly visible from the perfect match between the smoothed free charge densities and the bound charge distribution, computed from a finite difference of the polarization profile obtained after the relaxation of the lattice degrees of freedom. The domain wall widths, of around six unit cells, are larger than in the conventional 180$^\circ$ neutral configurations. Since no oxygen vacancies, defects or dopant atoms are introduced in our simulations, all the previous physical quantities are the intrinsic limits of the system. Our results support the existence of an extra source of charge at the domains walls to explain the enhancement of the conductivity observed in some domains walls of prototypical, insulating in bulk, perovskite oxides.

Theoretical constraints, as well as constraints from direct searches, precision tests of the standard model, the cosmic microwave background and matter power spectra, and cosmic gamma rays, are included. We find that a relatively light particle with mass between an MeV and a few GeV and an electric or magnetic dipole as large as $\sim 3\times 10^{-16}e$ cm (roughly $1.6\times10^{-5} μ_B$) satisfies all experimental and observational bounds. Some of the remaining parameter space may be probed with forthcoming more sensitive direct searches and with the Gamma-Ray Large Area Space Telescope.

description: Tests are conducted to investigate the temporal relationship between farmland prices and the return to farmland. The return to land is found, as expected, to be a leading indicator of the price of farmland. The use of the ex post return as an input in a transfer function model with land price as an output resulted in a 23% reduction in the MSE obtained from a univariate land price model.

description: Electrocardiograms (ECG) analysis is one of the most important ways to diagnose heart disease. This paper proposes an efficient ECG classification method based on Wasserstein scalar curvature to comprehend the connection between heart disease and mathematical characteristics of ECG. The newly proposed method converts an ECG into a point cloud on the family of Gaussian distribution, where the pathological characteristics of ECG will be extracted by the Wasserstein geometric structure of the statistical manifold. Technically, this paper defines the histogram dispersion of Wasserstein scalar curvature, which can accurately describe the divergence between different heart diseases. By combining medical experience with mathematical ideas from geometry and data science, this paper provides a feasible algorithm for the new method, and the theoretical analysis of the algorithm is carried out. Digital experiments on the classical database with large samples show the new algorithm's accuracy and efficiency when dealing with the classification of heart disease.

description: We construct the ($β$-deformed) partition function hierarchies with $W$-representations. Based on the $W$-representations, we analyze the superintegrability property and derive their character expansions with respect to the Schur functions and Jack polynomials, respectively. Some well known superintegrable matrix models such as the Gaussian hermitian one-matrix model (in the external field), $N\times N$ complex matrix model, $β$-deformed Gaussian hermitian and rectangular complex matrix models are contained in the constructed hierarchies.

description: This paper investigates the simultaneous and dynamic nature of the relationship between structure, conduct, and performance (S-C-P) with particular reference to the U.S. food and tobacco processing sector. The empirical results confirm the essentially simultaneous nature of the S-C-P system. Profit margins and advertising intensity interact within a simultaneous framework while concentration evolves slowly over time without responding much to the current economic environment.
TW Hya: an old protoplanetary disc revived by its planet

description: Dark rings with bright rims are the indirect signposts of planets embedded in protoplanetary discs. In a recent first, an azimuthally elongated AU-scale blob, possibly a planet, was resolved with ALMA in TW Hya. The blob is at the edge of a cliff-like rollover in the dust disc rather than inside a dark ring. Here we build time-dependent models of TW Hya disc. We find that the classical paradigm cannot account for the morphology of the disc and the blob. We propose that ALMA-discovered blob hides a Neptune mass planet losing gas and dust. We show that radial drift of mm-sized dust particles naturally explains why the blob is located on the edge of the dust disc. Dust particles leaving the planet perform a characteristic U-turn relative to it, producing an azimuthally elongated blob-like emission feature. This scenario also explains why a 10 Myr old disc is so bright in dust continuum. Two scenarios for the dust-losing planet are presented. In the first, a dusty pre-runaway gas envelope of about 40 Earth mass Core Accretion planet is disrupted, e.g., as a result of a catastrophic encounter. In the second, a massive dusty pre-collapse gas giant planet formed by Gravitational Instability is disrupted by the energy released in its massive core. Future modelling may discriminate between these scenarios and allow us to study planet formation in an entirely new way -- by analysing the flows of dust and gas recently belonging to planets, informing us about the structure of pre-disruption planetary envelopes.

Broad relaxation spectrum and the field theory of glassy dynamics for pinned elastic systems

description: We study thermally activated, low temperature equilibrium dynamics of elastic systems pinned by disorder using one loop functional renormalization group (FRG). Through a series of increasingly complete approximations, we investigate how the field theory reveals the glassy nature of the dynamics, in particular divergent barriers and barrier distributions controling the spectrum of relaxation times. A naive single relaxation time approximation for each wavevector is found to be unsatisfactory. A second approximation based on a random friction model, yields a size (L) dependent log-normal distribution of relaxation times (mean barriers ~L^θand variance ~ L^{θ/2}) and a procedure to estimate dynamical scaling functions. Finally, we study the full structure of the running dynamical effective action within the field theory. We find that relaxation time distributions are non-trivial (broad but not log-normal) and encoded in a closed hierarchy of FRG equations. A thermal boundary layer ansatz (TBLA) appears as a consistent solution. It extends the one discovered in the statics which was shown to embody droplet thermal fluctuations. Although perturbative control remains a challenge, the structure of the dynamical TBLA which encodes barrier distributions opens the way for deeper understanding of the field theory approach to glasses.

description: LaTiO$_3$ is known as Mott-insulator which orders antiferromagnetically at $T_{\rm N}=146$ K. We report on results of thermal expansion and temperature dependent x-ray diffraction together with measurements of the heat capacity, electrical transport measurements, and optical spectroscopy in untwinned single crystals. At $T_{\rm N}$ significant structural changes appear, which are volume conserving. Concomitant anomalies are also observed in the dc-resistivity, in bulk modulus, and optical reflectivity spectra. We interpret these experimental observations as evidence of orbital order.

description: In an age where “green” has become the buzzword du jour from rooftop gardens to corporate taglines “green chemistry” stands out as the rallying cry for industries eager to position them as environmentally responsible. But beneath the glossy veneer of sustainability lies a critical question: Is this movement a genuine scientific revolution or merely a fresh coat of paint over entrenched practices? Let us delve into the complexities of this so-called sustainable chemistry and ask: Is it a solution or an illusion?
Performance Evaluation of Stochastic Bipartite Matching Models

description: We consider a stochastic bipartite matching model consisting of multi-class customers and multi-class servers. Compatibility constraints between the customer and server classes are described by a bipartite graph. Each time slot, exactly one customer and one server arrive. The incoming customer (resp. server) is matched with the earliest arrived server (resp. customer) with a class that is compatible with its own class, if there is any, in which case the matched customer-server couple immediately leaves the system; otherwise, the incoming customer (resp. server) waits in the system until it is matched. Contrary to classical queueing models, both customers and servers may have to wait, so that their roles are interchangeable. While (the process underlying) this model was already known to have a product-form stationary distribution, this paper derives a new compact and manageable expression for the normalization constant of this distribution, as well as for the waiting probability and mean waiting time of customers and servers. We also provide a numerical example and make some important observations.

Monitoring the resonantly driven Jaynes-Cummings oscillator by an external two-level emitter: A cascaded open-systems approach

description: We address the consequences of backaction in the unidirectional coupling of two cascaded open quantum subsystems connected to the same reservoir at different spatial locations. In the spirit of [H. J. Carmichael, Phys. Rev. Lett. 70, 2273 (1993)], the second subsystem is a two-level atom, while the first transforms from a driven empty cavity to a perturbative QED configuration and ultimately to a driven Jaynes-Cummings (JC) oscillator through a varying light-matter coupling strength. For our purpose, we appeal at first to the properties of resonance fluorescence in the statistical description of radiation emitted along two channels -- those of forwards and sideways scattering -- comprising the monitored output. In the simplest case of an empty cavity coupled to an external atom, we derive analytical results for the nonclassical fluctuations in the fields occupying the two channels, pursuing a mapping to the bad-cavity limit of the JC model to serve as a guide for the description of the more involved dynamics. Finally, we exemplify a conditional evolution for the composite system of a critical JC oscillator on resonance coupled to an external monitored two-level target, showing that coherent atomic oscillations of the target probe the onset of a second-order dissipative quantum phase transition in the source.
