Spatial development and the expanding European integration of the Hungarian banking system
Creators: name: Gál, Zoltán
Publisher: name: RKK, Pécs
Year: 2004

description: The paper is concerned with the development stages and the spatial transformation of the Hungarian banking system in the economic transition & post-transition periods. It gives an overview of the development tendencies of the financial re-integration into the global market and particularly concentrates on the spatial polarisation factors (concentration de-concentration; centralisation decentralisation) which affect banking. The paper explores the arguments behind the extremely high centralisation of headquarter functions in Budapest and the factors that have impact on the establishment of locally-regionally based banks. This is followed by an introduction of the different organisational (institutional) and territorial (location strategies) level of the Hungarian banking system, dealing with either the domestic or the international financial central-function of Budapest and the reorganisation of the bank network and with its social consequences (financial exclusion) in the regions. The paper argues that EU membership is not a dramatic event in the integration process of the Hungarian banking sector, partly due to its particular ownership structure, the integration of the banking sector has already taken place. The paper concludes that the EMU integration could have been affected more adversely the Hungarian regions already characterised by the endogenous disparities, which are to a large extent rooted in the deficiency of their financial base.

description: Recovery of ground-state degeneracy in two-dimensional square ice is a significant challenge in the field of geometric frustration with far-reaching fundamental implications, such as realization of vertex models and understanding the effect of dimensionality reduction. We combine experiments, theory, and numerical simulations to demonstrate that sheared square colloidal ice partially recovers the ground-state degeneracy for a wide range of field strengths and lattice shear angles. Our method opens an avenue to engineer a novel class of frustrated micro- and nano-structures based on sheared magnetic lattices in a wide range of soft- and condensed-matter systems.

Pure Spinor Formalism as an N=2 Topological String
Creators: name: Berkovits, Nathan
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Following suggestions of Nekrasov and Siegel, a non-minimal set of fields are added to the pure spinor formalism for the superstring. Twisted $\hat c$=3 N=2 generators are then constructed where the pure spinor BRST operator is the fermionic spin-one generator, and the formalism is interpreted as a critical topological string. Three applications of this topological string theory include the super-Poincare covariant computation of multiloop superstring amplitudes without picture-changing operators, the construction of a cubic open superstring field theory without contact-term problems, and a new four-dimensional version of the pure spinor formalism which computes F-terms in the spacetime action.

 MATERIAL EXAMINED. — South Madagascar. ATIMO VATAE, stn DW 3555, 2 ventral valves with partly damaged anterior part.
DEPTH RANGE. — 455- 458 m.
REMARKS
 Of the eight present-day species of Stenosarina known (Logan 2007) only S. crosnieri (Cooper, 1983) has been recorded from the Indian Ocean, where it has been identified from 430-700 m depth off the north-western side of Madagascar (Cooper 1983). The two specimens recorded here from South Madagascar extend the geographical range of the genus but, while the material is poorly preserved, the smooth surface, small concave symphytium and nearly straight beak are characteristic of Stenosarina and suggest attribution to this genus.

description: We analyse theoretically for the first time to our knowledge the perfect phase matching of guided TE and TM modes with a multilayer waveguide composed of linear isotropic dielectric materials. Alongside strict investigation into dispersion relations for multilayer systems, we give an explicit qualitative explanation for the phenomenon of mode matching on the basis of the standard one-dimensional homogenization technique, and discuss the minimum number of layers and the refractive index profile for the proposed device scheme. Direct applications of the scheme include polarization-insensitive, intermodal dispersion-free planar propagation, efficient fibre-to-planar waveguide coupling and, potentially, mode filtering. As a self-sufficient result, we present compact analytical expressions for the mode dispersion in a finite, N-period, three-layer dielectric superlattice.

In particular we discuss model independent predictions for B^0 -> D^0 pi^0 and B^0 -> D^*0 pi^0, and update the comparison using new experimental data. We show why HQET alone is insufficient to give these results. SCET predictions are also reviewed for other B and Lambda_b decay channels that are not yet tested by data.

description: How is Africa reported in the British press and why? This question is the centrepiece of this study. With the application of a longitudinal research approach – a rarity in this field, this study unravels comprehensively, the UK press coverage of Africa.
Using a continuous 26-year sample duration, spanning from 01 January 1992 to 31 December 2017 and the usage of five British national newspapers, comprising of the broadsheets (The Guardian, The Financial Times, The Times) and the tabloids (The Daily Mail, and The Sun), this study sets itself apart from past studies in this field, which have been largely dominated by event-based research.
In the conduct of this study, mixed research methods - quantitative content analysis and qualitative interviews were applied. This study discovered that the topics of African articles reported in the UK press were mixed, same as the actors and the tone of language used in describing Africa. Also, it was newly discovered in this study that the size of African articles became consistently more detailed from 2008 to 2017.
In line with most previous studies in this field, this study further confirmed that the journalists used to cover Africa in UK newspapers were exclusively Western journalists; the representation of Africa as a single country dominated the coverage; South Africa remained the most visible African country reported; African articles were dominantly reported in the inside pages.
However, some of these results were not uniform in the five individual newspapers applied to this study. While the more detailed coverage of Africa could be noted in The Daily Mail, The Guardian, and The Times, it was the opposite case for The Financial Times and The Sun.
These results may have been products of multiple influences and reasons, some of which emanate from within the media organisations, while some of the other factors are from outside of the media and they collectively determine and define the direction of Africa’s coverage in the British press.

REMARKS
 Species of the genus Eucalathis are common in all the oceans of the world and range greatly in depth. Six species have been recorded from the Indian Ocean: E. rotundata Cooper, 1981; costellata Cooper, 1981; fasciculata Cooper, 1973; magna Cooper, 1981; murrayi (Davidson, 1878); and rugosa Cooper, 1973 (Logan 2007). E. magna is very rare in the investigated material, represented by only one specimen. It was originally described, also based on one specimen, from the West of Heard Island at a depth of 790 m by Cooper (1981a). The present finding extends its geographical range.
 This species is characterized by a large size for the genus and almond-like outline. Both in outline and ornamentation E. magna strongly resembles Terebratulina species. Cooper (1981a: 17) indicated the absence of deltidial plates, however, although minute they are present, both in the specimen from off South of Madagascar and the holotype.

Photogeochemistry of minerals under anoxic conditions
Creators: name: Liu, Winnie
Publisher: name: No Publisher Supplied
Year: 2021

description: Photogeochemistry, photochemical reactions with natural minerals and aqueous species, has influenced the biogeochemistry of Earth. Excitation of electrons in semi-conducting materials such as minerals can initiate thermodynamically unfavorable reactions. In particular, reactions caused by high energy UV radiation during early Earth could have influenced the surface environment of Earth by changing the availability of chemical species. This period of time is characterized by the lack of oxygen and enhanced UV radiation due to the absence of ozone. Photochemical reactions in anoxic environments are performed using a 450 W Hg lamp and specially made quartz reaction cells. The photochemistry of rhodochrosite (MnCO3), pyrite (FeS2), green rust ([Fe(II)1−x Fe(III)x(OH)2]x+.[(x/n)An−, mH2O]x−), amorphous Fe(II) silicate, and Fe(II) smectites were studied. UV irradiation of rhodochrosite and the Fe(II) silicates resulted in oxidation of the minerals. For rhodochrosite, a Mn(III) oxyhydroxide mineral manganite (γ-MnOOH) as well as H2 gas was produced. This demonstrates that mineral photochemistry is capable of producing manganese oxides abiotically from rhodochrosite under anoxic conditions. The irradiation of pyrite, particularly in the presence of dissolved Fe(II), resulted in the dissolution of pyrite and the release of sulfate and Fe(II). This process is a mechanism of weathering pyrite under anoxic conditions using light. The irradiation of green rust resulted in the production of magnetite (Fe3O4) and the irradiation of the two types of Fe(II) silicates resulted in the oxidation of Fe(II) without the formation of a secondary mineral phase. These reactions are previously unrecognized oxidation and/or transformation mechanisms under anoxic conditions that could have important implications for our understanding of the Archean S, Fe, and Mn cycles.
A Bayesian Nonparametric Conditional Two-sample Test with an Application to Local Causal Discovery

description: For a continuous random variable $Z$, testing conditional independence $X \perp\!\!\!\perp Y |Z$ is known to be a particularly hard problem. It constitutes a key ingredient of many constraint-based causal discovery algorithms. These algorithms are often applied to datasets containing binary variables, which indicate the 'context' of the observations, e.g. a control or treatment group within an experiment. In these settings, conditional independence testing with $X$ or $Y$ binary (and the other continuous) is paramount to the performance of the causal discovery algorithm. To our knowledge no nonparametric 'mixed' conditional independence test currently exists, and in practice tests that assume all variables to be continuous are used instead. In this paper we aim to fill this gap, as we combine elements of Holmes et al. (2015) and Teymur and Filippi (2020) to propose a novel Bayesian nonparametric conditional two-sample test. Applied to the Local Causal Discovery algorithm, we investigate its performance on both synthetic and real-world data, and compare with state-of-the-art conditional independence tests.

description: The asymmetry of the magnetization reversal process in exchange biased Fe/FeF$_2$ has been studied by magneto-optical Kerr effect. Qualitatively different transverse magnetization loops are observed for different directions of the cooling and the measuring field. These loops can be simulated by a simple calculation of the total energy density which includes the relevant magnetic anisotropies and coherent magnetization rotation only. Asymmetric magnetization reversal is shown to originate from the unidirectional anisotropy and may be observed if the external measuring field is not collinear with either the exchange bias or the easy axis of the antiferromagnetic epitaxial FeF$_2$(110) layer.

description: In this paper we survey some work on representations of $B_n$ given by the induced action on a homology module of some space. One of these, called the Lawrence-Krammer representation, recently came to prominence when it was shown to be faithful for all $n$. We will outline the methods used, applying them to a closely related representation for which the proof is slightly easier. The main tool is the Blanchfield pairing, a sesquilinear pairing between elements of relative homology. We discuss two other applications of the Blanchfield pairing, namely a proof that the Burau representation is not faithful for large $n$, and a homological definition of the Jones polynomial. Finally, we discuss possible applications to the representation theory of the Hecke algebra, and ultimately of the symmetric group over fields of non-zero characteristic.

description: Quantum Language Models (QLMs) in which words are modelled as quantum superposition of sememes have demonstrated a high level of model transparency and good post-hoc interpretability. Nevertheless, in the current literature word sequences are basically modelled as a classical mixture of word states, which cannot fully exploit the potential of a quantum probabilistic description. A full quantum model is yet to be developed to explicitly capture the non-classical correlations within the word sequences. We propose a neural network model with a novel Entanglement Embedding (EE) module, whose function is to transform the word sequences into entangled pure states of many-body quantum systems. Strong quantum entanglement, which is the central concept of quantum information and an indication of parallelized correlations among the words, is observed within the word sequences. Numerical experiments show that the proposed QLM with EE (QLM-EE) achieves superior performance compared with the classical deep neural network models and other QLMs on Question Answering (QA) datasets. In addition, the post-hoc interpretability of the model can be improved by quantizing the degree of entanglement among the words.

Livestock gains were modest but should increase more rapidly in 1974. Compared with 1973, crop production in 1974 is expected to be off somewhat unless weather again is unusually good. Soviet grain and oilseed import requirements are down sharply because of good 1973 crops.

description: Women in academia tend to take on the caretaker role in their departments by fulfilling most of the less promotable service work like mentoring. The perceived fit between this service and the communal stereotype of women creates expectations that women should take on these roles, which can lead to backlash if women violate these expectations. This study investigates gendered expectations in academia by evaluating whether women faculty experience more backlash for declining a student’s mentorship request than their male counterparts. Participants read a profile of a faculty member (male or female) and an email exchange between that faculty member and a student requesting mentorship. The faculty member either declined or accepted the request and participants rated the faculty member on interpersonal measures. Results indicated that men and women faculty were both rated more negatively by students when they declined the request, suggesting that women can say no to mentoring without the burden of gendered backlash. Given that some predicted effects approached significance, it is important to understand other factors that may impact perceptions, including whether the reason for declining, field of study (i.e., STEM), and the gender of student may impact the extent of backlash. This work furthers our understanding of whether women faculty can say no to service and focus on more promotable tasks without hurting their reputations.

DEPTH RANGE. — 187-249 m
DESCRIPTION
Shell small (maximum observed length 5.9 mm), ventribiconvex, widely subtriangular in outline. Shell surface covered with 10-12 strong, single, rounded costae. Costae weakly beaded posteriorly, nearly smooth in anterior half except where crossed by elevated growth lines; intercostal spaces wide. Anterior commissure rectimarginate. Hinge line slightly curved. Beak low, suberect. Foramen large, subcircular, mesothyrid; deltidial plates small, triangular (Fig. 10E, G). Ventral valve interior with small teeth; pedicle collar wide. Dorsal valve interior with massive inner socket ridges extending beyond margin. Cardinal process distinct. Crura long, slender; crural processes short, can be slightly incurved. Loop short with an incomplete transverse band (Fig. 10 I-O). Low, short median ridge visible on inner dorsal valve. Inner margin of both valves crenulated.
REMARKS
 In size, outline and ornamentation the new species described here is most similar to Eucalathis rotundata. In the strong costation E. daphneae n. sp. also resembles E. rugosa Cooper, 1973, differing in size and outline, as well as in the character of costae. E. rugosa possesses beaded, strongly tuberculate ribs (Cooper 1973c; Laurin 1997; Bitner 2008, 2009, 2010); in E. daphneae ribs are nearly smooth. However, the species described by Cooper (1973c, 1981a) have a typical loop for the genus, whereas in all specimens collected in North-West Madagascar the loop has an incomplete transverse band.
 Among Recent representatives of chlidonophorids only in the species Melvicalathis macroctena (Zezina, 1981) may the loop be incomplete (Zezina 1981b; Lee et al. 2008), however, it possesses broad, triangular in cross-section costae with smooth ridges without any tubercles, differing greatly from E. daphneae. In the fossil chlidonophorids an incomplete loop is observed only in the Eocene-Oligocene genus Orthothyris Cooper, 1955 (see Bitner & Müller 2015).

An approach involving the determination of maximum vertical distance between the curves is considered here as a method to assess whether a survival advantage exists between different groups of patients. The method is illustrated on a dataset containing survival times of patients treated with two cancer treatment regimes, one involving treatment by chemotherapy alone, and the other by treatment with both chemotherapy and radiotherapy.

description: I review the progress made on the physics of relativistic jets from black hole systems in the context of the analogy between AGN and microquasars that was proposed one decade ago. If the emerging empirical correlations between the observational properties of stellar and supermassive black holes will become more robust, we will use them to determine the mass and spin of black holes, independently of theoretical models. Microquasars are fossils of sources of Gamma-ray bursts (GRBs) of long duration, and their kinematics provides observational clues on the physics of collapsars. If jets in GRBs, microquasars and AGN are due to a unique universal magnetohydrodynamic mechanism, synergy between the research on these three different classes of cosmic objects will lead to further progress in black hole physics and astrophysics.

description: We investigate the possibility of realizing a spintronic memristive device based on the dependence of the tunnel conductance on the relative angle between the magnetization of the two magnetic electrodes in in-plane magnetized tunnel junctions. For this, it is necessary to design a free layer whose magnetization can be stabilized along several or even any in-plane direction between the parallel and the antiparallel magnetic configurations. We experimentally show that this can be achieved by exploiting antiferromagnet-ferromagnet exchange interactions in a regime where the antiferromagnet is thin enough to induce enhanced coercivity and no exchange bias. The frustration of exchange interactions at the interfaces due to competing ferro- and antiferromagnetic interactions is at the origin of an isotropic dissipation mechanism yielding isotropic coercivity. From a modeling point of view, it is shown that this isotropic dissipation can be described by a dry friction term in the Landau-Lifshitz-Gilbert equation. The influence of this dry friction term on the magnetization dynamics of an in-plane magnetized layer submitted to a rotating in-plane field is investigated both analytically and numerically. The possibility to control the free layer magnetization orientation in an in-plane magnetized magnetic tunnel junction by using the spin transfer torque from an additional perpendicular polarizer is also investigated through macrospin simulation. It is shown that the memristor function can be achieved by the injection of current pulses through the stack in the presence of an in-plane static field transverse to the reference layer magnetization, the aim of which is to limit the magnetization rotation between 0° and 180°.

description: We propose a novel strategy for energy-efficient dynamic computation offloading, in the context of edge-computing-aided beyond 5G networks. The goal is to minimize the energy consumption of the overall system, comprising multiple User Equipment (UE), an access point (AP), and an edge server (ES), under constraints on the end-to-end service delay and the packet error rate performance over the wireless interface. To reduce the energy consumption, we exploit low-power sleep operation modes for the users, the AP and the ES, shifting the edge computing paradigm from an always on to an always available architecture, capable of guaranteeing an on-demand target service quality with the minimum energy consumption. To this aim, we propose an online algorithm for dynamic and optimal orchestration of radio and computational resources called Discontinuous Computation Offloading (DisCO). In such a framework, end-to-end delay constraints translate into constraints on overall queueing delays, including both the communication and the computation phases of the offloading service. DisCO hinges on Lyapunov stochastic optimization, does not require any prior knowledge on the statistics of the offloading traffic or the radio channels, and satisfies the long-term performance constraints imposed by the users. Several numerical results illustrate the advantages of the proposed method.

description: Conflict in the newly formed South Sudan has had devastating effects on the nation’s food security. Many food security metrics overlook factors of agriculture, such as seasonality, access to agricultural inputs; or the effects of displacement of small farm holders due to conflict. In light of these complexities, constructs were adapted from Whole Measures for Community Food Systems (WMCFS) , and evaluated for their appropriateness in articulating the food situation in Unity State, South Sudan . This study used a pilot study approach, triangulating publicly available, qualitative and quantitative datasets from the Famine Early Warning System Network, United Nations, Government of South Sudan, humanitarian workers, and social media. Data were coded for relevance to metrics using Atlas.ti software, and scored based on WMCFS. In all, the WMCFS pilot showed the promise of a participatory planning process to secure lasting community food security, and focus on long-term agricultural development rather than food aid.

description: Agricultural output in Western Europe hit a new high in 1973, led by a record grain crop. Red meat production was up from the low level of 1972, but still below 1971. Pork, poultry meat and milk production set new records. Further increases in livestock and crop production are expected in 1974. Prices of most agricultural products rose in Western Europe but not as much as surging world prices. The value of agricultural trade increased sharply, mostly due to higher commodity prices; U.S. agricultural exports to Western Europe rose by 67 percent to $5.6 billion. The West European economy continued strong but was much troubled by inflation. As a result of the energy crisis, a low rate of economic growth is expected in 1974 along with severe inflationary and balance of payments problems. The European Community and other governments increased price supports and other aids to farmers in 1973. Major decisions are pending on agricultural and trade policy

description: Firstly, I report on a recent work --carried out with T. Hambye and E. de Rafael-- on how to use the large-Nc expansion to calculate unfactorized contributions from the strong penguin operators, and their impact on observables such as epsilon'/epsilon and the Delta I = 1/2 rule. Secondly, based on work done with M. Golterman, I explain how this calculation allows one to predict some rather dramatic consequences for quenched QCD. This may help explain the present discrepancy between lattice and experimental results for epsilon'/epsilon. The emphasis of this article is put on the explanation of the method of calculation used, which is fully analytic. This allows one to build some intuition and understand the role played by the different hadronic scales in determining the size of the different contributions.

title: Bacterial phase variation associated with repetitive DNA
Creators: name: Saunders, Nigel John
Publisher: name: The Open University

description: Phase variation is mechanism of phenotypic switching used by many pathogenic bacterial species. This thesis describes work on three aspects of phase variation. Mathematical models are described which can be used to determine the rate of phase variation and subsequently the influence of variation rate and fitness differences associated with the altered phenotype on population structure. An approach to whole genome analysis has been developed which has been used to identify putative phase variable contingency genes in H. pylori, T. pallidum and N. meningitidis. This has identified many new contingency genes likely to be involved in host - bacterium and bacterium population interactions. Finally, a detailed molecular investigation of the promoter of the phase variable opc gene of N. meningitidis is presented. In this it is shown that the promoter located homopolymeric tract controls transcription by affecting the relative spacing and facing of promoter components, that this determines RNA polymerase binding to the promoter, and that this interaction involves direct contact of the α-subunit of RNA polymerase with the promoter. In addition it is shown that transcription is dependent upon an IHF consensus sequence in the opc promoter.

description: The EXtreme PREcision Spectrograph (EXPRES) is an environmentally stabilized, fiber-fed, $R=137,500$, optical spectrograph. It was recently commissioned at the 4.3-m Lowell Discovery Telescope (LDT) near Flagstaff, Arizona. The spectrograph was designed with a target radial-velocity (RV) precision of 30$\mathrm{~cm~s^{-1}}$. In addition to instrumental innovations, the EXPRES pipeline, presented here, is the first for an on-sky, optical, fiber-fed spectrograph to employ many novel techniques---including an "extended flat" fiber used for wavelength-dependent quantum efficiency characterization of the CCD, a flat-relative optimal extraction algorithm, chromatic barycentric corrections, chromatic calibration offsets, and an ultra-precise laser frequency comb for wavelength calibration. We describe the reduction, calibration, and radial-velocity analysis pipeline used for EXPRES and present an example of our current sub-meter-per-second RV measurement precision, which reaches a formal, single-measurement error of 0.3$\mathrm{~m~s^{-1}}$ for an observation with a per-pixel signal-to-noise ratio of 250. These velocities yield an orbital solution on the known exoplanet host 51 Peg that matches literature values with a residual RMS of 0.895$\mathrm{~m~s^{-1}}$.

description: The Coronet Cluster in the nearby R CrA dark cloud offers the rare opportunity to study at least four "class I" protostellar sources as well as one candidate "class 0" source, a Herbig Ae star, and a candidate brown dwarf within a few square arcminutes - most of them detected at radio- and X-ray wavelengths. These sources were observed with the Very Large Array (VLA) at 3.5cm on nine occasions in 1998, spread over nearly four months. The source IRS 5, earlier shown to emit circularly polarized radio emission, was observed to undergo a flux increase accompanied by changes in its polarization properties. Comparison with VLA measurements taken in January 1997 allows for some analysis of longer-term variability. In addition to this radio monitoring, we analyze archival Chandra and XMM-Newton X-ray data of these sources. Three class I protostars are bright enough for X-ray spectroscopy, and we perform a variability analysis for these sources, covering a total of 154 ksec spread over more than two and a half years. Also in X-rays, IRS 5 shows the most pronounced variability, whilst the other two class I protostars IRS 1 and IRS 2 have more stable emission. X-ray data is also analyzed for the recently identified candidate class 0 source IRS 7E, which shows strong variability as well as for the Herbig Ae star R CrA for which we find extremely hot X-ray-emitting plasma. For IRS 1,2 and 5, the hydrogen column densities derived from the X-ray spectra are at about half the values derived with near-infrared techniques, a situation similar to what has been observed towards some other young stellar objects.
