description: Classical pairwise image registration methods search for a spatial transformation that optimises a numerical measure that indicates how well a pair of moving and fixed images are aligned. Current learning-based registration methods have adopted the same paradigm and typically predict, for any new input image pair, dense correspondences in the form of a dense displacement field or parameters of a spatial transformation model. However, in many applications of registration, the spatial transformation itself is only required to propagate points or regions of interest (ROIs). In such cases, detailed pixel- or voxel-level correspondence within or outside of these ROIs often have little clinical value. In this paper, we propose an alternative paradigm in which the location of corresponding image-specific ROIs, defined in one image, within another image is learnt. This results in replacing image registration by a conditional segmentation algorithm, which can build on typical image segmentation networks and their widely-adopted training strategies. Using the registration of 3D MRI and ultrasound images of the prostate as an example to demonstrate this new approach, we report a median target registration error (TRE) of 2.1 mm between the ground-truth ROIs defined on intraoperative ultrasound images and those propagated from the preoperative MR images. Significantly lower (>34%) TREs were obtained using the proposed conditional segmentation compared with those obtained from a previously-proposed spatial-transformation-predicting registration network trained with the same multiple ROI labels for individual image pairs. We conclude this work by using a quantitative bias-variance analysis to provide one explanation of the observed improvement in registration accuracy.

description: Inverse reinforcement learning (IRL) is the problem of finding a reward function that generates a given optimal policy for a given Markov Decision Process. This paper looks at an algorithmic-independent geometric analysis of the IRL problem with finite states and actions. A L1-regularized Support Vector Machine formulation of the IRL problem motivated by the geometric analysis is then proposed with the basic objective of the inverse reinforcement problem in mind: to find a reward function that generates a specified optimal policy. The paper further analyzes the proposed formulation of inverse reinforcement learning with $n$ states and $k$ actions, and shows a sample complexity of $O(n^2 \log (nk))$ for recovering a reward function that generates a policy that satisfies Bellman's optimality condition with respect to the true transition probabilities.

description: The one-dimensional $p$-wave superconductor proposed by Kitaev has long been a classic example for understanding topological phase transitions through various methods, such as examining Berry phase, edge states of open chains and, in particular, aspects from quantum entanglement of ground states. In order to understand the amount of information carried in the entanglement-related quantities, here we study topological phase transitions of the model with emphasis of using the deep learning approach. We feed different quantities, including Majorana correlation matrices (MCMs), entanglement spectra (ES) or entanglement eigenvectors (EE) originated from Block correlation matrices (BCMs), into the deep neural networks for training, and investigate which one could be the most useful input format in this approach. We find that ES is indeed too compressed information compared to MCM or EE. MCM and EE can provide us abundant information to recognize not only the topological phase transitions in the model but also phases of matter with different $U$(1) gauges, which is not reachable by using ES only.

description: The dynamics of an anapole seen as dark matter at low energies is studied by solving the Schrödinger-Pauli equation in a potential involving Dirac-delta and its derivatives in three-dimensions. This is an interesting mathematical problem that, as far as we know, has not been previously discussed. We show how bound states emerge in this approach and the scattering problem is formulated (and solved) directly. The total cross section is in full agreement with independent calculations in the standard model.

description: The curriculum for Design and Technology in secondary schools in England and Wales has been under review. Withpolicy makers questioning not only the position the subject occupies within the curriculum, but also the value Designand Technology holds. As a result, Design and Technology’s future, as a subject, is uncertain. Set against a background of policy and curriculum change, this paper presents the findings of a research study designed to elicit the perceptions of, and gain an insight into the way Key Stage 3 pupils (11 - 14 years) view Design and Technology. Utilising the concept of the original PATT Tool (Raat & de Vries, 1986), and building upon the work of previous studies undertaken nationally or globally (de Vries, 1988; de Klerk Wolters, 1989; Bame & Dugger, 1993; Volk & Yip 1999; Van Rensburg, Ankiewicz & Myburgh, 1999; Ankiewicz & Van Rensburg 2001; Becker & Maunsaiyat 2002; Chikasanda, Williams, Otrel-Cass & Jones, 2011; Gaotlhobogwe, 2010; Ardies, De Maeyer & Gijbels, 2012, 2013), the fundamental aim of the research at inception was to investigate the perceptions of pupils with respect to their understanding of what is technology education. Although simplistic in origin, the findings presented illustrate that this is far from the case. Framed epistemologically within a social practice lens (Suchman, Blomberg, Orr & Trigg, 1999), the research tool used was a questionnaire 458 comprising of a series of open and closed questions. Administered by teachers who recorded both electronically and in hard copy, the sample was drawn randomly via those choosing to respond. Responses were gathered from 173 schools throughout England and Wales with data being collected over an eight month period commencing in July 2012. Analysis of the data elicited a number of key findings which are presented here. Although exclusively based on the perspective of school pupils in England and Wales, it is anticipated that the findings will provide both stimulus and a starting point forresearchers working under similar curriculum constraints or revisions. Given the nature of the curriculum changes whichhave occurred, the research team intend to develop the tool further and expand it to include pupils in the post compulsory age bracket (16 - 18years) and the primary education age bracket.

description: The ultraviolet/optical telescope (UVOT) onboard the Neil Gehrels Swift Observatory is capable of imaging with 7 lenticular filters and of taking slitless spectra with 2 grisms. Both image and grism data have been widely used to study gamma-ray bursts, supernovae and other ultraviolet/optical transients, and proved UVOT is a powerful instrument in time-domain astronomy. However, the second order contamination, for blue sources, strongly limits the red end of ultraviolet (UV) grism spectra. This, in turn, reduces the valid wavelength range to only about 33% of the total. However, to explore the broadband spectral energy distribution of GRBs at the early stage, a larger valid wavelength range is required. Hence based on the uvotpy package, we propose a method to remove the second order contamination from UV grism spectra (nominal mode) up to about 4000Å, i.e., about 70% of the full wavelength range. The 1-sigma systematic uncertainty of this method is about 11.2%. In addition, if a source is red enough, the red end of the valid range could reach about 5000Å. The source code is available on GitHub.

description: After making a cold weld by pressing two clean metal surfaces together, upon gradually separating the two pieces a metallic nanowire is formed, which progressively thins down to a single atom before contact is lost. In previous experiments [1,2] we have observed that the stability of such nanowires is influenced by electronic shell filling effects, in analogy to shell effects in metal clusters [3]. For sodium and potassium at larger diameters there is a crossover to crystalline wires with shell-closings corresponding to the completion of additional atomic layers. This observation completes the analogy between shell effects observed for clusters and nanowires.

description: Globalisation and European integration constitute new possibilities and challenges for the Hungarian agro-food sector. Based on a model developed by the authors, the paper analyses the ways and means of the strategic development of the Hungarian food chain. The application of the cost directing strategy comes up against considerable difficulties. Concentration is a general process in the agro-food sector. The strategy of product differentiation is an indispensable prerequisite of increasing the competitiveness of small and middle-sized food producers. Concentration in domestic trade is a specific problem. The safeguarding of the interests of farmers and companies of the food industry should be increased by a more rigorous application of the Competition Act. ------------- A globalizáció és az európai integráció egyidejűleg jelent új lehetőségeket és kihívásokat a magyar élelmiszergazdaság számára.

description: A model for computing acoustic scattering by a swimbladdered fish with coupling to surrounding fish tissue that is assumed to behave as a homogeneous fluid, is presented. Mathematically, this corresponds to considering the problem of two penetrable scatterers immersed in a homogeneous medium, one of which is wholly embedded in the other. The model is formulated in the frame of boundary integral equations whose solution is achieved using the Boundary Element Method (BEM) for a planar triangle mesh. The numerical implementation is verified against benchmark solutions reported in the literature. The model is then applied to a specimen of \textit{Merluccius hubbsi}, whose morphometry was determined by CT scanning, for evaluating its forward and backscattering responses. From the acoustic scattering viewpoint, the swimbladder is considered as a gas-filled object while the flesh constituting the fish body acts like a weak scatterer. The numerical results suggest the swimbladder and the fish body responses, when fully coupled, can lead to substantial differences with respect to the simplified models normally in use in the area of aquatic ecosystem research.

What type of Type I error? Contrasting the Neyman-Pearson and Fisherian approaches in the context of exact and direct replications.

description: The replication crisis has caused researchers to distinguish between exact replications, which duplicate all aspects of a study that could potentially affect the results, and direct replications, which duplicate only those aspects of the study that are thought to be theoretically essential to reproduce the original effect. The replication crisis has also prompted researchers to think more carefully about the possibility of making Type I errors when rejecting null hypotheses. In this context, the present article considers the utility of two types of Type I error probability: the Neyman-Pearson long run Type I error rate and the Fisherian sample-specific Type I error probability. It is argued that the Neyman-Pearson Type I error rate is inapplicable in social science because it refers to a long run of exact replications, and social science deals with irreversible units (people, social groups, and social systems) that make exact replications impossible. Instead, the Fisherian sample-specific Type I error probability is recommended as a more meaningful way to conceptualize false positive results in social science because it can be applied to each sample-specific decision about rejecting the same substantive null hypothesis in a series of direct replications. It is concluded that the replication crisis may be partly (not wholly) due to researchers’ unrealistic expectations about replicability based on their consideration of the Neyman-Pearson Type I error rate across a long run of exact replications.

description: We compute Seidel's mirror map for abelian varieties by constructing the homogeneous coordinate rings from the Fukaya category of the symplectic mirrors. The computations are feasible as only linear holomorphic disks contribute to the Fukaya composition in the case of the planar Lagrangians used. The map depends on a symplectomorphism $ρ$ representing the large complex structure monodromy. For the example of the two-torus, different families of elliptic curves are obtained by using different $ρ$ which are linear in the universal cover. In the case where $ρ$ is merely affine linear in the universal cover, the commutative elliptic curve mirror is embedded in noncommutative projective space. The case of Kummer surfaces is also considered.

description: We continue the analysis of our previous articles which were devoted to type-I parametric down conversion, the extension to type-II being straightforward. We show that entanglement, in the Wigner representation, is just a correlation that involves both signal and vacuum fluctuations. An analysis of the detection process opens the way to a complete description of parametric down conversion in terms of pure Maxwell electromagnetic waves.

We study the behaviour of the thermopower, Peltier coefficient and thermal conductance both in the sequencial tunneling regime and in the regime where Kondo correlations develope. Both cases of linear response and non-equilibrium induced by strong temperature gradients are considered. The thermopower is a very sensitive tool to detect Kondo correlations. It changes sign both as a function of temperature and temperature gradient. We also discuss violations of the Wiedemann-Franz law.

description: We have shown that all "single-photon" and "photon-pair" states, produced in atomic transitions, and in parametric down conversion by nonlinear optical crystals, may be represented by positive Wigner densities of the relevant sets of mode amplitudes. The light fields of all such states are represented as a real probability ensemble (not a pseudoensemble) of solutions of the unquantized Maxwell equation.
 The local realist analysis of light-detection events in spatially separated detectors requires a theory of detection which goes beyond the currently fashionable single-mode photon theory. It also requires us to recognize that there is a payoff between detector efficiency and signal-noise discrimination. Using such a theory, we have demonstrated that all experimental data, both in atomic cascades and in parametric down conversions, have a consistent local realist explanation based on the unquantized Maxwell field.
 Finally we discuss current attempts to demonstrate Schroedinger-cat-like behaviour of microwave cavities interacting with Rydberg atoms. Here also we demonstrate that there is no experimental evidence which cannot be described by the unquantized Maxwell field.
 We conclude that misuse of the Photon Concept has resulted in a mistaken recognition of "nonlocal" phenomena.

description: Agriculture is certainly not the most decisive element of the expansion of EU towards eastern central Europe. However, it is one of the most complex issues, if not the very most one, on the way of integrating the new members. Nevertheless, the implementation of the Common Agricultural Policy in the field of rural development might help to ease the present rural disparities and unfavourable spatial trends in Hungary, as well as in the other candidate countries. Rural economy is a complex and dynamic system (Allanson, P. - Withby, M. 1996), and agriculture should be treated as a part of it (Nijkamp, P. 1996). Rural development includes a great number of issues and various aspects. The authors focus, in a spatial aspect, on income distribution and employment issues, and presents some significant indicators of regions (corresponding to the NUTS-2 level) established by means of aggregation of traditional administrative units, e. g. counties (NUTS-3). The regional disparities observed in Hungary are discussed in a European context. Finally, some of the authors' results deriving from an analysis of statistical sub-regions (NUTS-4) are summarised. Policy aspects, SAPARD, and related crucial documents, e. g. the National Development Programme and the National Rural Development Programme, are not discussed here. ------------- A mezőgazdaság ugyan minden bizonnyal nem a legdöntőbb eleme az Európai Unió kelet-közép-európai bővítésének, de az egyik legfontosabb – ha nem a legfontosabb – kérdése az új tagok integrálásának. A Közös Agrárpolitika meghonosítása a vidékfejlesztés területén elősegítheti a jelenlegi vidéki diszparitások és kedvezőtlen térségi tendenciák enyhítését, Magyarországon csakúgy, mint a többi EU-tagjelölt országban. A vidékgazdaság komplex és dinamikus rendszer (Allanson, P. - Withby, M. 1996), és a mezőgazdaságot annak részeként kell kezelni (Nijkamp, P. 1996). A vidékfejlesztés számos kérdést és sokféle szempontot ölel fel. A szerzők térbelileg a jövedelem-megoszlás és foglalkoztatás kérdéseire összpontosítják figyelmüket Bemutatják a NUTS-2 szintű régiók néhány fontos jellemzőjét amelyek a hagyományos közigazgatási egységek, pl. a megyék (NUTS-3) egybevonása útján alakultak ki. A Magyarországon tapasztalható diszparitásokat európai kontextusban tárgyalják. Végezetül a szerzők néhány, a statisztikai al-régiók (NUTS-4) elemzéséből adódó eredményt összegeznek. A politikai vonatkozásokat a SAPARD-ot és a kapcsolatos kulcsfontosságú dokumentumokat – mint pl. a Nemzeti Fejlesztési Programot és a Nemzeti Vidékfejlesztési Programot – nem tárgyalják.

description: In this paper, existing work on credence goods is extended to include a "diagnosis" stage whereby ill-informed consumers rely on a third party to certify that food products have beneficial characteristics. This compares to existing models of credence goods which focus only on a "treatment" stage, i.e., food is simply certified as having such characteristics. Adding the diagnosis stage allows for "deep capture" by food producers who attempt to influence regulatory outcomes on what quality claims can be made about food products: specifically an innovator, the “expert”, can expend resources to “nudge” regulatory assessment of quality samples in a positive direction, assuming also that there are economies of scope between innovation and influence.
Charge transfer in LaVO$_3$/LaTiO$_3$ multilayers: strain-controlled dimensionality of interface metallicity between two Mott insulators

description: We use density functional theory plus dynamical mean-field theory to demonstrate the emergence of a metallic layer at the interface between the two Mott insulators LaTiO$_3$ and LaVO$_3$. The metallic layer is due to charge transfer across the interface, which alters the valence state of the transition metal cations close to the interface. Somewhat counter-intuitively, the charge is transferred from the Ti cations with formal $d^1$ electron configuration to the the V cations with formal $d^2$ configuration, thereby increasing the occupation difference of the $t_{2g}$ states. This can be understood as a result of a gradual transition of the charge transfer energy, or electronegativity, across the interface. The spatial extension of the metallic layer, in particular towards the LaTiO$_3$ side, can be controlled by epitaxial strain, with tensile strain leading to a localization within a thickness of only two unit cells. Our results open up a new route for creating a tunable quasi-two-dimensional electron gas in materials with strong electronic correlations.

description: We report measurements of the inclusive reaction, p pbar -> p X pbar, in events where either or both the beam-like final-state baryons were detected in Roman-pot spectrometers and the central system was detected in the UA2 calorimeter. A Double-Pomeron-Exchange (DPE) analysis of these data and single diffractive data from the same experiment demonstrates that, for central masses of a few GeV, the extracted Pomeron-Pomeron total cross section exhibits an enhancement which exceeds factorization expectations by an order-of-magnitude. This may be a signature for glueball production. The enhancement is shown to be independent of uncertainties connected with possible non-universality of the Pomeron flux factor. Based on our analysis, we present DPE cross section predictions, for unit (1 mb) Pomeron-Pomeron total cross section, at the Tevatron, LHC and the 920 GeV fixed-target experiment, HERA-B.

description: Together with the rest of the economy, the agricultural sector in Kyrgyzstan has undergone crucial reforms during the transition period following the collapse of the Soviet Union. The policies influencing agricultural incentives, i.e. farmgate prices, have also changed substantially. Recent macroeconomic developments, such as the booming gold mining sector and an increasing inflow of workers' remittances on the one hand, and increasing import prices on the other hand, are also likely to have an impact on agricultural incentives through the influence on the exchange rate. This paper aims at investigating the impact of both direct agricultural policies and changing macroeconomic conditions on agricultural incentives for the case of Kyrgyzstan. Nominal Rates of Assistance (NRAs) are estimated in order to quantify direct distortions of agricultural prices resulting from the policies in the agricultural sector. NRA estimates show that domestic prices for major food crops in Kyrgyzstan are raised beyond world market prices due to a general encouragement of food-crop production based on food self-sufficiency goals. Relative to food crops, export crops tend to be penalized by lower and less stable NRAs as well as by poor market integration. In the second step, the True Protection Concept is employed in order to analyse relative incentives between importable, exportable and nontradable sectors in the Kyrgyz economy. The true-protection analysis shows that around half of the burden of the price increase for importables is shifted to the exportables sector, including agricultural exportables. This means that if prices in the importable sector increase in response to exogenous factors or certain trade policies, domestic exporters, both agricultural and non-agricultural, would be taxed implicitly. Since the Kyrgyz government seeks to promote exports, findings from the present study may serve as a background for future trade and agricultural policy development.

description: We describe the design and measurement of feedhorn-coupled, transition-edge sensor (TES) polarimeters with two passbands centered at 220 GHz and 280 GHz, intended for observations of the cosmic microwave background. Each pixel couples polarized light in two linear polarizations by use of a planar orthomode transducer and senses power via four TES bolometers, one for each band in each linear polarization. Previous designs of this detector architecture incorporated passbands from 27 GHz to 220 GHz; we now demonstrate this technology at frequencies up to 315 GHz. Observational passbands are defined with an on-chip diplexer, and Fourier-transform-spectrometer measurements are in excellent agreement with simulations. We find coupling from feedhorn to TES bolometer using a cryogenic, temperature-controlled thermal source. We determine the optical efficiency of our device is $η$ = 77%$\pm$6% (75%$\pm$5%) for 220 (280) GHz, relative to the designed passband shapes. Lastly, we compare two power-termination schemes commonly used in wide-bandwidth millimeter-wave polarimeters and find equal performance in terms of optical efficiency and passband shape.

description: Gravitational microlensing has proven to be a powerful probe of both the structure at the heart of quasars and the mass function of compact objects in foreground lenses. This paper examines the potential of gravitational microlensing in probing the scale of structure in absorbing material within the lensing galaxy. We find that, in this high optical depth regime, significant variations in the equivalent width of absorption features can be induced, although the details of these are dependent upon the scale of structure of the absorbing material. The paper concludes with an examination of the absorption line variability observed in the gravitationally lensed quasar PKS1830-211, demonstrating how this may indicate the presence of small scale structure in the cold molecular gas present within the lensing galaxy.

description: The N-vector cubic model relevant, among others, to the physics of the randomly dilute Ising model is analyzed in arbitrary dimension by means of an exact renormalization-group equation. This study provides a unified picture of its critical physics between two and four dimensions. We give the critical exponents for the three-dimensional randomly dilute Ising model which are in good agreement with experimental and numerical data. The relevance of the cubic anisotropy in the O(N) model is also treated.
