description: The present paper provides an analysis of agricultural sigma convergence in four old Member States and in Hungary. The analysis was derived from the output and input data from the Economic Accounts for Agriculture between 1990-2005. The results obtained indicate significant convergence in the old Member States and Hungary. First of all this held true for incomes but the inputs do not reveal a perceptible pattern. However, in terms of outputs Hungary lags well behind the Old Member States, but the difference is not nearly as great for inputs. This can probably be explained by the fact that the rate of increase for inputs is higher than for producer prices, meaning the relative prices of agricultural output and input products (agricultural terms of trade) are increasing, which decelerates the convergence process. Even the improvement in efficiency can only partly compensate for these negative effects. The results of the analysis underline the importance of the number of employees of which the continual and significant decrease largely determines convergence itself and also its rate.

description: Time Projection Chambers (TPCs) working in combination with Gas Electron Multipliers (GEMs) produce a very sensitive detector capable of observing low energy events. This is achieved by capturing photons generated during the GEM electron multiplication process by means of a high-resolution camera. The CYGNO experiment has recently developed a TPC Triple GEM detector coupled to a low noise and high spatial resolution CMOS sensor. For the image analysis, an algorithm based on an adapted version of the well-known DBSCAN was implemented, called iDBSCAN. In this paper a description of the iDBSCAN algorithm is given, including test and validation of its parameters, and a comparison with DBSCAN itself and a widely used algorithm known as Nearest Neighbor Clustering (NNC). The results show that the adapted version of DBSCAN is capable of providing full signal detection efficiency and very good energy resolution while improving the detector background rejection.

description: An optical speckle potential is used to investigate the static and dynamic properties of a Bose-Einstein condensate in the presence of disorder. For strong disorder the condensate is localized in the deep wells of the potential. With smaller levels of disorder, stripes are observed in the expanded density profile and strong damping of dipole and quadrupole oscillations is seen. Uncorrelated frequency shifts of the two modes are measured for a weak disorder and are explained using a sum-rules approach and by the numerical solution of the Gross-Pitaevskii equation.

description: A modification of the Random Forest algorithm for the categorization of traffic situations is introduced in this paper. The procedure yields an unsupervised machine learning method. The algorithm generates a proximity matrix which contains a similarity measure. This matrix is then reordered with hierarchical clustering to achieve a graphically interpretable representation. It is shown how the resulting proximity matrix can be visually interpreted and how the variation of the methods' metaparameter reveals different insights into the data. The proposed method is able to cluster data from any data source. To demonstrate the methods' potential, multiple features derived from a traffic simulation are used in this paper. The knowledge of traffic scenario clusters is crucial to accelerate the validation process. The clue of the method is that scenario templates can be generated automatically from actual traffic situations. These templates can be employed in all stages of the development process. The results prove that the procedure is well suited for an automatic categorization of traffic scenarios. Diverse other applications can benefit from this work.

Monte Carlo investigations of a high resolution Small Field-Of-View gamma camera

Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: At the time of writing there have been no publications describing Monte Carlo simulations tracking low energy gamma and X-ray photons (less than 200 keV) through Small Field-Of-View (SFOV) photon detection systems. A literature search using the Web of Science (1970-2019) and Scopus (1960-2019) with the keywords “gamma, camera” AND “monte carlo” AND “small” OR “compact” showed 200 and 215 results respectively, but without any photon tracking studies. Two SFOV systems were modelled using PENELOPE v2008 Monte Carlo: the Portable Imaging X-ray Spectrometer detector, a pre-scintillator detector system for non-medical use, and a thallium doped caesium iodide scintillator based Compact Gamma Camera used for medical imaging. Each system uses an electron multiplying charge coupled device modelled as an 8 mm x 8 mm x 5 ?m thick monolithic silicon detector. These simulations demonstrated the Fano-limited energy spectrum, and that the modelled fluorescence do not record some of the caesium and iodine Kα and Kβ? fluorescence photons if the source event originated closer to the boundary of the Monte Carlo accumulator. The corroborative experimental response of the PIXS detector using cadmium-109 showed broadening of the Ag Kα, Kβ? peaks, consistent with the energy resolution being broadened owing to incomplete charge collection, drift and transfer through the shift and gain registers, and also due to noise from the detector readout. As the distribution of photoelectrons from the EMCCD output is stochastic, a premise of distinguishing between zero and single photoelectron as an input, with thresholding using noise peak plus 5? worked well for a gain potential difference ?HV between 33.5 V and 39.5 V, with the system cooled to 256.0 ? 0.1 K. Finally, a GEANT4 v10.5 simulation of caesium iodide crystal comprised of columns 100 ?m x 100 ?m x 1500 ?m thick demonstrated a greater number of optical photons propagating by internal reflection to the 5 ?m silicon detector, when laterally wrapped with 1 ?m aluminium compared either to an unwrapped columnar crystal, laterally wrapped monolithic or unwrapped monolithic crystals.

description: root samples of brown sarson (Brassica rapa L.) were collected from three districts of Kashmir valley viz., Anantnag, Srinagar and Baramulla. The bacterial population per gram of all the root sample was determined and it was observed that one of the site Hugam in the District Anantnag had the highest bacterial population of 4.35 × 105 cfu/g of fresh weight) and site Nowgam in the District Srinagar had the lowest bacterial population of 6.8 × 103 cfu/g of fresh weight). A total of 81 morphologically dissimilar isolates were selected and characterized on Gram’s staining, cell and colony morphology basis and it was observed that Gram negative bacteria formed the dominant group. The colony characterization revealed that circular forms dominated, likewise the colonies with entire margins and convex elevation dominated among all the isolates. The metabolic properties of isolated bacterial root endophytes revealed that all the isolates can metabolize glucose and galactose but some isolates did not metabolize maltose and sucrose respectively. All the isolates were screened for indole acetic acid (IAA) production and it was observed that 44 isolates among all produced IAA with the average production of 8.15 μg/mL.

description: The low-energy electronic structure of icosahedral fullerenes is studied within the field-theory model. In the field model, the pentagonal rings in the fullerene are simulated by two kinds of gauge fields. The first one, non-abelian field, follows from so-called K spin rotation invariance for the spinor field while the second one describes the elastic flow due to pentagonal apical disclinations. For fullerene molecule, these fluxes are taken into account by introducing an effective field due to magnetic monopole placed at the center of a sphere. Additionally, the spherical geometry of the fullerene is incorporated via the spin connection term. The exact analytical solution of the problem (both for the eigenfunctions and the energy spectrum) is found.

description: Das deutsche Gesundheitssystem steht aktuell vor großen wirtschaftlichen und medizinischen Herausforderungen. Digitalisierung kann dazu beitragen, diesen Herausforderungen zu begegnen, beispielsweise im Bereich der Arzneimitteltherapiesicherheit (AMTS). Besonders viele Schnittstellenproblematiken im Versorgungsprozess in Hinblick auf AMTS gibt es im ambulanten Sektor zwischen den Stakeholdern niedergelassener Arzt und Apotheke im Bereich der Verordnung und Transkription von Medikationsdaten. Diese Daten liegen oftmals nicht richtig, vollständig, rechtzeitig und in lesbarer Form vor. Die Implementierung eines digitalisierten Datenaustauschs könnte dies beheben und würde auf aggregierter Ebene zu einer Verbesserung der Qualität und Wirtschaftlichkeit der Versorgung führen. Auf Ebene der Stakeholder herrscht jedoch Unsicherheit darüber, ob dies für den einzelnen Stakeholder langfristig insgesamt eine positive oder negative Nutzenwirkung hat, da den zu erwartenden Kosteneinsparungen auch verschiedene Implementierungskosten entgegenstehen. Dies stellt eine Implementierungshürde dar. Ein Lösungsansatz wäre es, die Kostenträger für einen definierten Erprobungszeitraum zur Kostenübernahme zu verpflichten. In diesem Zeitraum wird die Wirkung der Digitalisierung im Versorgungs- und Medikationsprozess evaluiert. Ein positives Evaluationsergebnis würde zu einer Überwindung der Implementierungshürden führen; ein negatives Evaluationsergebnis würde Verbesserungspotential bei der Umsetzung der Digitalisierung und der Ausgestaltung der Healthcare IT im AMTS-Bereich aufzeigen.

description: We investigate the X-ray number counts in the 1-2 Ms Chandra Deep Fields (CDFs) to determine the contributions of faint X-ray source populations to the extragalactic X-ray background (XRB). X-ray sources were separated into Active Galactic Nuclei (AGN), star-forming galaxies, and Galactic stars based on several criteria. We find that AGN continue to dominate the number counts in the 0.5-2.0 keV and 2-8 keV bands. At flux limits of ~2.5e-17 erg cm-2 s-1 (0.5-2.0 keV) and ~1.4e-16 erg cm-2 s-1 (2-8 keV), the overall AGN source densities are 7166 (+304/-292) and 4558 (+216/-207) sources deg-2, respectively; these are factors of ~10-20 higher than found in the deepest optical spectroscopic surveys. While still a minority, the number counts of star-forming galaxies climb steeply such that they eventually achieve source densities of 1727 (+187/-169) and 711 (+270/-202) sources deg-2 at the CDF 0.5-2.0 keV and 2-8 keV flux limits, respectively. Adopting recent XRB flux densities measurements, the CDFs resolve a total of 89.5% (+5.9%/-5.7%) and 86.9% (+6.6%/-6.3%) of the extragalactic 0.5-2.0 keV and 2-8 keV XRBs, respectively. Extrapolation of the number-count slopes can easily account for the entire 0.5-2.0 keV and 2-8 keV XRBs to within statistical errors. We also revisit the reported differences between the CDF-North and CDF-South number counts, finding that the two fields are consistent except for sources in the 2-8 keV band below F(2-8 keV)~1e-15 erg cm-2 s-1, where deviations gradually increase to ~3.9 sigma.

description: The topological kagome magnet (TKM) Fe3Sn2 exhibits unusual topological properties, flat electronic bands, and chiral spin textures, making it an exquisite materials platform to explore the interplay between topological band structure, strong electron correlations, and magnetism. Here we report the first synthesis of high-quality epitaxial (0001) Fe3Sn2 films with large intrinsic anomalous Hall effect close to that measured in bulk single crystals. In addition, we measured a large, anisotropic anomalous Nernst coefficient Syx of 1.26 μV/K, roughly 2-5x greater than that of common ferromagnets, suggesting the presence of Berry curvature sources near the Fermi level in this system. Crucially, the realization of high-quality Fe3Sn2 films opens the door to explore emergent interfacial physics and create novel spintronic devices based on TKMs by interfacing Fe3Sn2 with other quantum materials and by nanostructure patterning.

description: In the far future of an accelerating LCDM cosmology, the cosmic web of large-scale structure consists of a set of increasingly isolated halos in dynamical equilibrium. We examine the approach of collisionless dark matter to hydrostatic equilibrium using a large N-body simulation evolved to scale factor a = 100, well beyond the vacuum--matter equality epoch, a_eq ~ 0.75, and 53/h Gyr into the future for a concordance model universe (Omega_m ~ 0.3, Omega_Lambda ~ 0.7). The radial phase-space structure of halos -- characterized at a < a_eq by a pair of zero-velocity surfaces that bracket a dynamically active accretion region -- simplifies at a > 10 a_eq when these surfaces merge to create a single zero-velocity surface, clearly defining the halo outer boundary, rhalo, and its enclosed mass, mhalo. This boundary approaches a fixed physical size encompassing a mean interior density ~ 5 times the critical density, similar to the turnaround value in a classical Einstein-deSitter model. We relate mhalo to other scales currently used to define halo mass (m200, mvir, m180b) and find that m200 is approximately half of the total asymptotic cluster mass, while m180b follows the evolution of the inner zero velocity surface for a < 2 but becomes much larger than the total bound mass for a > 3. The radial density profile of all bound halo material is well fit by a truncated Hernquist profile. An NFW profile provides a somewhat better fit interior to r200 but is much too shallow in the range r200 < r < rhalo.

description: We study the emergence of entropy in gravitational production of dark matter particles, ultra light scalars minimally coupled to gravity and heavier fermions, from inflation to radiation domination (RD). Initial conditions correspond to dark matter fields in their Bunch-Davies vacua during inflation. The "out" states are correlated particle-antiparticle pairs, and the distribution function is found in both cases. In the adiabatic regime the density matrix features rapid decoherence by dephasing from interference effects in the basis of "out" particle states, effectively reducing it to a diagonal form with a concomitant von Neumann entropy. We show that it is exactly the entanglement entropy obtained by tracing over one member of the correlated pairs. Remarkably, for both statistics the entanglement entropy is similar to the quantum kinetic entropy in terms of the distribution function with noteworthy differences stemming from pair correlations. The entropy and the kinetic fluid form of the energy momentum tensor all originate from decoherence of the density matrix. For ultra light scalar dark matter, the distribution function peaks at low momentum $\propto 1/k^3$ and the specific entropy is $\ll 1$. This is a hallmark of a \emph{condensed phase} but with vanishing field expectation value. For fermionic dark matter the distribution function is nearly thermal and the specific entropy is $\mathcal{O}(1)$ typical of a thermal species. We argue that the functional form of the entanglement entropy is quite general and applies to alternative production mechanisms such as parametric amplification during reheating.

These sources, designated as XB and XA, have X-ray absorption columns of ~3e23 cm-2 equivalent to AV ~180 mag. They are associated with the VLA centimeter radio sources 10E and 10W, respectively. XA is the counterpart of the near-infrared source IRS 7, whereas XB has no K-band counterpart above 19.4 mag. This indicates that XB is younger than typical Class I protostars, probably a Class 0 protostar or in an intermediate phase between Class 0 and Class I. The X-ray luminosity of XB varied between 29

An investigation of the complexity of downtown public space
Creators: name: Monadizadeh, Behrouz
Publisher: name: University of British Columbia
Year: 2009

description: The public space of the contemporary downtown is a complex and controversial phenomenon. In the past the territory of the public and that of the private were sharply defined by the property lines dividing the landscape into the city blocks and the network of the streets. Such clear-cut divisions between the public and private spaces of downtown are not valid anymore; neither are the political, financial and legal issues related to their ownership, development, maintenance and use. By typology and physical spread the public space of downtown has developed far beyond the street, into the office plazas and atria, and indoor spaces of the shopping malls and mixed-use downtown centers. These new types are dubious creations as they are developed by the private funds but are intended to be used by the public. Therefore the public space of the contemporary downtown is a controversial conception whereas its use is conditioned by the interests of the private developers and proprietors, which tend to prefer the wealthy and privileged consumers. The increasing diversity and complexity, as well as the contested state of the contemporary downtown public space demands renewing our conceptions of it. This thesis is an attempt in that direction. The present work is a combination of two separate pieces of research on the theme of downtown public space. The first research, as covered in chapters one and two, is a broad investigation. It is a study of the main types of public space that constitute the public realm of the North American downtown, and a study of the downtown realm in its entirety. Therefore, it is a correlated study of the parts and the whole. The objective of this broad investigation is to understand the complexity of downtown public space. This knowledge will inform planning and urban design to make decisions and conduct the course of change and development in the downtown environment in a more insightful manner. The second research, as covered in chapter three, is a focused analysis of the parameters that need to be considered in the evaluation and/or design of urban open space as a particular type of public space. The proposed criteria is used for the evaluation of two cases of public space in downtown Vancouver.
Inertia-gravity-wave scattering by geostrophic turbulence

description: In rotating stratified flows including in the atmosphere and ocean, inertia-gravity waves (IGWs) often coexist with a geostrophically balanced turbulent flow. Advection and refraction by this flow lead to wave scattering, redistributing IGW energy in the position--wavenumber phase space. We give a detailed description of this process by deriving a kinetic equation governing the evolution of the IGW phase-space energy density. The derivation relies on the smallness of the Rossby number characterising the geostrophic flow, which is treated as a random field with known statistics, and makes no assumption of spatial scale separation. The kinetic equation describes energy transfers that are restricted to IGWs with the same frequency, as a result of the timescale separation between waves and flow. We formulate the kinetic equation on the constant-frequency surface -- a double cone in wavenumber space -- using polar spherical coordinates, and we examine the form of the two scattering cross sections involved, which quantify energy transfers between IGWs with, respectively, the same and opposite directions of vertical propagation. The kinetic equation captures both the horizontal isotropisation and the cascade of energy across scales that result from scattering. We focus our attention on the latter to assess the predictions of the kinetic equation against direct simulations of the three-dimensional Boussinesq equations, finding good agreement.

Uniform Light-Cone Gauge for Strings in AdS_5 x S^5: Solving su(1|1) Sector
Creators: name: Arutyunov, Gleb

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We introduce a uniform light-cone gauge for strings propagating in AdS space-time. We use the gauge to analyze strings from the su(1|1) sector, and show that the reduced model is described by a quadratic action for two complex fermions. Thus, the uniform light-cone gauge allows us to solve the model exactly. We analyze the near BMN spectrum of states from the su(1|1) sector and show that it correctly reproduces the 1/J corrections. We also compute the spectrum in the strong coupling limit, and derive the famous λ^{1/4} asymptotics. We then show that the same string spectrum can be also derived by solving Bethe ansatz type equations, and discuss their relation to the quantum string Bethe ansatz for the su(1|1) sector.
description: 26 pages, Latex, v2: comparison to the strong coupling expansion of the quantum string Bethe ansatz is added, discussion of the winding sector is extended, references added

Nonreciprocal surface magnetoelastic dynamics
Creators: name: Yu, Tao
Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: Motivated by recent experiments, we investigate the nonreciprocal magnetoelastic interaction between the surface acoustic phonons of dielectric non-magnetic substrates and magnons of proximity nanomagnets. The magnetization dynamics exerts rotating forces at the edges of the nanomagnet that causes the nonreciprocal interaction with surface phonons due to its rotation-momentum locking. This coupling induces the nonreciprocity of the surface phonon transmission and a nearly complete phonon diode effect by several (tens of) magnetic nanowires of high (ordinary) magnetic quality. Phase-sensitive microwave transmission is also nonreciprocal that can pick up clear signals of the coherent phonons excited by magnetization dynamics. Nonreciprocal pumping of phonons by precessing magnetization is predicted using Landauer-Büttiker formalism.

description: Bean Common Mosaic Virus (BCMV) causes one of the most serious diseases affecting common bean production. This potyvirus is spread non-persistently by aphids and is also seed-borne. In present investigation out of 132 genotypes selected for screening for BCMV only 8 genotypes (WB-399, WB-640, WB-359 & WB-375, WB-494, WB-933 & WB-939, WB-335) were found phenotypically resistant against it, which was later ascertained by molecular analysis by different microsatellite markers. The variable number of bands produced by different primers ranged from 5 to 22 with an average of 11.4 bands per primer and with level of polymorphism 24.5%. Among the molecular markers used, SSR marker named 835 produced a maximum of 6 alleles, followed by marker 841 then by marker 827 then by BMD-1 followed by ROC-11then followed by marker EIF-4E then followed by SBD-5 and finally by SW-13 that produced 3 alleles each. The polymorphism information content (PIC) was calculated for all the markers, and was highest for Primer BMD-6 which exhibited PIC value of 0.49 and the lowest for the primer BMD-2 (0.22). Hence, primer BMD-6 was observed to be highly informative and serve as an effective and useful marker to determine the genetic differences among the common bean accessions and also to study the phylogenetic relationships.

description: We report late-time observations of the radio afterglow of GRB 030329. The light curves show a clear achromatic flattening at 50 days after the explosion. We interpret this flattening as resulting from the blast wave becoming trans-relativistic. Modeling of this transition enables us to make estimates of the energy content of the burst, regardless of the initial jet structure or the distribution of initial Lorentz factors of the ejecta. We find, in accordance with other events, that GRB 030329 is well-described by an explosion with total energy of a few times 10^51 erg expanding into a circumburst medium with a density of order unity.

description: The goal of this paper is to provide a method, which is able to find categories of traffic scenarios automatically. The architecture consists of three main components: A microscopic traffic simulation, a clustering technique and a classification technique for the operational phase. The developed simulation tool models each vehicle separately, while maintaining the dependencies between each other. The clustering approach consists of a modified unsupervised Random Forest algorithm to find a data adaptive similarity measure between all scenarios. As part of this, the path proximity, a novel technique to determine a similarity based on the Random Forest algorithm is presented. In the second part of the clustering, the similarities are used to define a set of clusters. In the third part, a Random Forest classifier is trained using the defined clusters for the operational phase. A thresholding technique is described to ensure a certain confidence level for the class assignment. The method is applied for highway scenarios. The results show that the proposed method is an excellent approach to automatically categorize traffic scenarios, which is particularly relevant for testing autonomous vehicle functionality.

description: This study analyzes the sensitivity of trade flows to trade barriers from gravity equations, using different econometric techniques recently highlighted in the literature. Specifically, we compare a benchmark OLS fixed effects specification a la Feenstra (2002) with three emerging estimation methods: the standard Heckman correction for selection bias, to account for zero trade flows; the Eaton and Tamura (1994) Tobit estimator, to solve limited-dependent variable issues; and, finally, the Poisson pseudo-maximum-likelihood (PPML) technique, to correct for the presence of heteroskedasticity. Our gravity model includes trade among 193 exporter and 99 importer countries, in 18 food industry sectors. The paper achieves two goals: First it provides estimates of the elasticity of substitution obtained using the four estimation techniques; Second, it gives a dimension to the trade reduction effect induced by existing border protection, by simulating the effect of a full trade liberalization scenario on 18 food sectors. The estimates reveal interesting variations in the elasticity of substitution across products and procedures. The simulation indicates that trade liberalization will strongly increase food exports, especially from emerging and developing countries.

description: The masses of heavy tetraquarks with hidden charm and bottom are calculated in the framework of the relativistic quark model. The tetraquark is considered as the bound state of a heavy-light diquark and antidiquark. The light quark in a heavy-light diquark is treated completely relativistically. The internal structure of the diquark is taken into account by calculating the diquark-gluon form factor in terms of the diquark wave functions. New experimental data on charmonium-like states above open charm threshold are discussed. The obtained results indicate that the X(3872) can be the tetraquark state with hidden charm. The masses of ground state tetraquarks with hidden bottom are found to be below the open bottom threshold.

Structural Investigation Of SAM68 Interaction With Hiv-1 RRE And REV
Creators: name: Mirza, Ayesha Hassan
Publisher: name: University of Leicester

Subjects: Uncategorized

description: Gene expression of retroviruses, such as those of HIV-1, requires transcription, alternative splicing, RNA export and translation steps. All these steps are highly regulated by interactions between viral proteins and cellular proteins. HIV-1 spliced RNAs are exported to the cytoplasm using the classical mRNA export pathway. The export of unspliced RNAs or partially spliced RNAs, however, needs the viral protein Rev (Regulator of Virion) and other cellular proteins including Sam68. This step is crucial for the viral life cycle because these unspliced RNAs are necessary for the expression of the viral structural proteins and for the viral replication. Rev exports unspliced RNA by binding an RNA motif of the HIV-1 RNA composed of approximately 351 nucleotides, which adopts specific secondary structures called an RRE (Rev Response Element). It has been demonstrated that Sam68 plays a crucial role in the export of unspliced RNAs by binding both Rev and the RRE. It is therefore, important to understand the interaction of Sam68 with a viral protein and RNA at molecular level to develop drugs that inhibit HIV-1 replication by disrupting this interaction. Structural and biophysical techniques used to study the interaction of Sam68 with RRE and Rev are described in this thesis. A novel construct of Sam68 designed to bind RRE and Rev simultaneously shows interaction with both binding partners and forms a ternary complex. The EMSA and ITC data provides insight into the binding affinity of Sam68 to RRE, which correlates with the binding affinity of Sam68 with (U/A)AA-N>15-(U/A)AA previously published by our lab. Structural investigation of the binary and ternary complex was carried out using X-ray crystallography. SEC-MALS data provides evidence of a complex formed by interaction of a Sam68 dimer, Rev dimer and one RRE molecule ~161kDa. The region of the RRE recognized by Sam68 is unknown. However, it is known that Sam68 specifically recognizes RNA sequences rich in adenines and uracils. We have analysed the RRE sequence and observed 5 A/U rich regions in the stem-loop structure of the RRE that could be a potential binding site for Sam68. Mutants of RRE have been designed to map the exact binding site of Sam68 on the RRE.
