description: Using the semiclassical quantum Boltzmann theory and employing the Dirac model with twist angle-dependent Fermi velocity we obtain results for the electrical resistivity, the electronic thermal resistivity, the Seebeck coefficient, and the Wiedemann-Franz ratio in near magic angle twisted bilayer graphene, as functions of doping density (around the charge-neutrality-point) and modified Fermi velocity $\tilde v$. The $\tilde v$-dependence of the relevant scattering mechanisms, i.e. electron-hole Coulomb, long-ranged impurities, and acoustic gauge phonons, is considered in detail. We find a range of twist angles and temperatures, where the combined effect of momentum-non-conserving collisions (long-ranged impurities and phonons) is minimal, opening a window for the observation of strong hydrodynamic transport. Several experimental signatures are identified, such as a sharp dependence of the electric resistivity on doping density and a large enhancement of the Wiedemann-Franz ratio and the Seebeck coefficient.

description: We include instanton effects in QCD sum rules for coupled scalar glueballs and mesons. We find a light glueball/sigma as in earlier studies without instantons, but in a lattice-type pure instanton model the light glueball/sigma is not found. In the 1-2 Gev region we now find that lightest I=0 meson, in the region of the f$_o$(1370), has no direct glueball mixing, with the instanton loop replacing the glueball component. The lightest scalar mainly glueball in the region of the f$_o$(1500) is sensitive to the choice of nonperturbative gluonic parameters.

description: The aim is to assess selected determinants which influence the conversion of the Czech farmers from conventional to organic or biodynamic agriculture. We assess farm’s efficiency (calculated by SFA), whether farm obtains AEM or LFA payments, if the farmer is “young” and the holding is a micro firm, and region. A random effects logistic regression model was estimated on the panel of Czech farms in 2005–2012. The results showed that efficiency of the farm is not a significant driver of conversion. On the other hand, the odds that the farm will change land management are significantly higher if it obtains subsidies. Also when the farm has < 10 employees and the farmer is > 40 years, the odds that it will switch are higher. If the farm is located Olomoucký region or Vysočina the odds for conversion are lower. The research is financed from IGA the grant No. 11110/1312/3160 of FEM, CULS.

description: The need for privacy-preserving analytics is higher than ever due to the severity of privacy risks and to comply with new privacy regulations leading to an amplified interest in privacy-preserving techniques that try to balance between privacy and utility. In this work, we present an efficient method for Text Classification while preserving the privacy of the content using Fully Homomorphic Encryption (FHE). Our system (named \textbf{Priv}ate \textbf{F}ast \textbf{T}ext (PrivFT)) performs two tasks: 1) making inference of encrypted user inputs using a plaintext model and 2) training an effective model using an encrypted dataset. For inference, we train a supervised model and outline a system for homomorphic inference on encrypted user inputs with zero loss to prediction accuracy. In the second part, we show how to train a model using fully encrypted data to generate an encrypted model. We provide a GPU implementation of the Cheon-Kim-Kim-Song (CKKS) FHE scheme and compare it with existing CPU implementations to achieve 1 to 2 orders of magnitude speedup at various parameter settings. We implement PrivFT in GPUs to achieve a run time per inference of less than 0.66 seconds. Training on a relatively large encrypted dataset is more computationally intensive requiring 5.04 days.

description: The potential of $n$-Higgs Doublet Models ($n$HDMs) contains a large number of SU(2)$_L$-preserving accidental symmetries as subgroups of the symplectic group Sp(2$n)$. To classify these, we introduce prime invariants and irreducible representations in bilinear field space that enable us to explicitly construct accidentally symmetric $n$HDM potentials. We showcase the classifications of symmetries and present the relationship among the theoretical parameters of the scalar potential for; (i) the Two Higgs Doublet Model (2HDM) and (ii) the Three Higgs Doublet Model (3HDM). We recover the maximum number of $13$ accidental symmetries for the 2HDM potential and for the first time, we present the complete list of $40$ accidental symmetries for the 3HDM potential.

description: The Hadamard representation of the Green's function of a quantum field on a curved space-time is a powerful tool for computations of renormalized expectation values. We study the Hadamard form of the Feynman Green's function for a massive charged complex scalar field in an arbitrary number of space-time dimensions. Explicit expressions for the coefficients in the Hadamard parametrix are given for two, three and four space-time dimensions. We then develop the formalism for the Hadamard renormalization of the expectation values of the scalar field condensate, current and stress-energy tensor. These results will have applications in the computation of renormalized expectation values for a charged quantum scalar field on a charged black hole space-time, and hence in addressing issues such as the quantum stability of the inner horizon.

description: In der vorliegenden Arbeit wird eine Synthese von 3,3-Diarylpropylamin-Wirkstoffen beschrieben, die als zentralen Syntheseschritt eine Hydroaminomethylierung von 1,1-Diarylethenen beinhaltet. Bei diesen Wirkstoffen handelt es sich um verschiedene Harninkontinenzmittel, die auf diesem Wege in Abhängigkeit vom Substitutionsmuster in einer maximal fünfstufigen Synthese in racemischer Form zugänglich sind. Aufgrund der ausschließlichen Wirksamkeit der R-konfigurierten Enantiomere werden im zweiten Teil der Arbeit zwei Konzepte für eine asymmetrische Synthese verfolgt: a) ligandgesteuerte enantioselektive Hydroaminomethylierung b) substratgesteuerte diastereoselektive Hydroaminomethylierung. Beide Konzepte führen allerdings nicht zu den gewünschten optisch aktiven Produkten. Zurückgeführt werden kann dieses zum einen auf eine Verdrängung der verwendeten chiralen Liganden vom Katalysatorkomplex durch das anwesende Amin und zum anderen auf die geringe Reaktivität der 1,1-Diarylethene. Im dritten Teil der Arbeit wird ein Verfahren beschrieben, das die Recyclisierung des Edelmetallkatalysators ermöglicht. Realisiert wird dieses durch die Verwendung eines Zweiphasensystems auf 1,2-Propylencarbonatbasis.
description: In this work the synthesis of 3,3-diarylpropylamine active substances is described, which involves a hydroaminomethylation of 1,1-diarylpropylamines as key step. These amines are active substances against urinary incontinence, which can be synthesised in racemic form in this way dependent on the substitution pattern in five steps at most. Due to the exclusive activity of the R-configurated enantiomer in the second part of the work two concepts for an asymmetric synthesis are investigated: a) ligand-directed enantioselective hydroaminomethylation b) substrate-directed diastereoselective hydroaminomethylation. However, both concepts do not provide the products in an optical active form. On the one hand this is caused by a displacement of the chiral ligand from the catalyst by the present amine and on the other hand by the low reactivity of the 1,1-diarylamine. In the third part of the work a method for the recycling of the noble metal catalyst is described. This is achieved by using a biphasic system based on 1,2-propylenecarbonate.

description: The aim of this paper is to analyse the development of Czech foreign trade in food products and beverages (the CPA groups 10 and 11 within the Classification System) and to evaluate the position of individual CPA groups and their products, even within the EU, using two indices of comparative advantage (RCA) and trade balances. The purpose is to contribute to a deeper understanding of the given issue as the analytical work dealing with whole Czech agrarian foreign trade is less focused on foods and drinks. However, they should be a core area of business, especially with regard to competitiveness of the agricultural sector. The sources of data on foreign trade are public databases of Czech Statistical Office (External Trade Database) and Eurostat (International Trade database ComExt). Regarding the time series, period of the years 2005-2013 is analysed. Significant changes in the sales and purchases of foodstuff and beverages were occurred in the context of accession to the EU but these changes are not in focus yet. The paper is engaged in the period when the Czech Republic has already been a member of the EU, and fully entrenched. The point is which results in foreign trade with. Results showed that value of Czech imports of food products and beverages in the years 2005-2013 increased in the larger extent than exports, and negative trade balance deepened by 51 % to 29.3 Bn CZK. The degree of coverage of imports by exports, however, improved from 73.0 % to 77.3 % due to lower dynamics of growth of imports than exports. Besides of the own assessment of the Czech food and beverage foreign trade, our work has consisted in specific transfer of the Combined Nomenclature to the nomenclature CPA. The methodological contribution is then our own list of customs codes, respectively their aggregations, belonging to the individual CPA disciplines. This should be useful for next analysis.

description: With the prospect of large numbers of $J/Ψ$ decay events becoming available in the near future, it is interesting to search for symmetry violating effects as probes of new physics and tests of the standard model. $J/Ψ$ decay events could provide the first observation of weak effects in otherwise strongly decaying particles. We calculate a T odd asymmetry in the $J/Ψ$ decay into photon plus lepton pair due to Z boson exchange. Extensions to hadronic final states are also discussed.

title: Fast continuous and discrete time approaches for smooth and nonsmooth optimization featuring time scaling and Tikhonov regularization
Creators: name: Karapetyants, Mikhail
Year: 2024

description: Die folgende Arbeit widmet sich der Lösung des klassischen Optimierungsproblems der Minimierung einer konvexen Funktion mit verschiedenen Methoden in kontinuierlicher und diskreter Zeit. Es werden sowohl glatte als auch nicht glatte Fälle der Zielfunktionen diskutiert. Der Schwerpunkt dieser Abhandlung liegt auf der Erzielung schneller Konvergenzraten für die Funktionswerte in Kombination mit der Konvergenz der Trajektorien der dynamischen Systeme oder Iterationen der Algorithmen. Besonderes Augenmerk wird auf die Tikhonov-Regularisierungstechnik gelegt, die bekanntermaßen dabei hilft, die schwache Konvergenz der Trajektorien (Iterationen) zur kontrollierten (zum Element der minimalen Norm aus der Menge aller Minimierer der Zielfunktion) starken Konvergenz zu verbessern. In einigen Fällen wird eine Zeitskalierung angewendet, um die Konvergenz der Funktionswerte zu beschleunigen. Es werden verschiedene numerische Experimente vorgestellt, um unser Verständnis der theoretischen Ergebnisse zu verbessern.
description: The following thesis is devoted to solving the classical optimization problem of minimizing a convex function via different methods in continuous and discrete time. Both smooth and nonsmooth cases of the objective functions will be discussed. The main focus throughout this manuscript is to obtain fast convergence rates for the function values combined with the convergence of the trajectories of the dynamical systems or iterates of the algorithms. Major attention is paid to the Tikhonov regularization technique, which is known to help improve the weak convergence of the trajectories (iterates) to the controlled (to the element of the minimal norm from the set of all minimizers of the objective function) strong one. In some cases, time scaling will be applied to accelerate the function values' convergence. Various numerical experiments are presented to improve our understanding of theoretical results.

Hedging and Cash Flow Risk in Ethanol Refining

Year: 2011
Subjects: Agricultural marketing

description: Interviews with ethanol refinery risk managers reveal that, at least for the firms represented, (a) working capital to fund margin accounts is limited so the optimal deployment of this capital is a major concern, and (b) these firms hedge with smaller positions than those indicated by the traditional price risk minimization theory. In response to those observations, this study examines the relationship between hedge outcome price risk and price risk induced intra hedge cash flow risk. A simulation analysis of a simple long hedge indicates that the sum of hedge outcome risk and intra hedge cash flow risk is minimized at hedging levels well below the levels that minimize only the hedge outcome risk. The model is generalized to apply to a commodity processor using ethanol refining as a specific example. While the preliminary results are promising, data deficiencies prevent pursuing the analysis to its logical completion. Steps for extending this study using higher quality data are proposed.

description: We study associative memory neural networks of the Hodgkin-Huxley type of spiking neurons in which multiple periodic spatio-temporal patterns of spike timing are memorized as limit-cycle-type attractors. In encoding the spatio-temporal patterns, we assume the spike-timing-dependent synaptic plasticity with the asymmetric time window. Analysis for periodic solution of retrieval state reveals that if the area of the negative part of the time window is equivalent to the positive part, then crosstalk among encoded patterns vanishes. Phase transition due to the loss of the stability of periodic solution is observed when we assume fast alpha-function for direct interaction among neurons. In order to evaluate the critical point of this phase transition, we employ Floquet theory in which the stability problem of the infinite number of spiking neurons interacting with alpha-function is reduced into the eigenvalue problem with the finite size of matrix. Numerical integration of the single-body dynamics yields the explicit value of the matrix, which enables us to determine the critical point of the phase transition with a high degree of precision.

Optimal Clock Speed of Single-Qubit Operations on Open Quantum Systems

Year: 2019
Subjects: subject: Quantum Physics (quant-ph)

description: Efficient implementation of quantum algorithms requires single- or multi-qubit gates with high fidelity. In this report, we report that the fidelity of single-qubit gate operations on open quantum systems has a maximum value corresponding to an optimum value of the drive-amplitude in the presence of drive-induced decoherence. To show this, we use a previously reported fluctuation-regulated quantum master equation [Phys. Rev. A 97, 063837 (2018)]. The fidelity is found to be a function of the drive-induced dissipative terms as well as the relaxation terms arising from the qubit-environment coupling; as a result, it behaves non-monotonically with the drive-amplitude. The existence of an optimum drive-amplitude implies that the single-qubit operations on open quantum systems would have an optimal clock speed.

description: In order to evaluate placement of artificial reefs in Huidong County and observe biological aggregating effect of fishery resources, background investigation and follow-up investigation were carried out for trawl fishing and gill-net fishing in Daxingshan artificial reef area. The biological resource density index (D), Margalef species richness index (R), Shannon-Winener diversity index (H’), and Pileou evenness index (J') were used to study diversity of water biological population and resource density. Trawl fishing investigation indicated that after placement of reefs, there was significant increase in quantity of species of nekton, total resource density, species richness index, and diversity index in reef area, which were 1.321, 2.07, 1.012 and 1.084 times the value before placement of reefs respectively. Gill-net fishing investigation indicated that after placement of reefs, the quantity of species of nekton, total resource density, species richness index, and diversity index in reef area were 2.571, 7.976, 2.399 and 2.667 times the value before placement of reefs respectively. After reef placement, fishes and crabs become dominant population. It showed that after reef placement, attraction effect of fishes is significant, community structure is obviously optimized, and water environment in reef area is significantly improved. Thus, it proved that the multiplication system through artificial reefs has been basically established in Daxingshan reef area of Huidong County.

description: The quest for a microscopic foundation of Thermodynamics is addressed within the Nonunitary Newtonian Gravity model through the study of a specific closed system, namely a three-dimensional harmonic nanocrystal. A numerical calculation of the nanocrystal von Neumann entropy as a function of time is performed, showing a sharp monotonic increase, followed by a stabilization at late times. This behavior is consistent with the emergence of a micro-canonical ensemble within the initial energy levels, signaling, in this way, the establishment of a non-unitary gravity-induced thermal equilibrium.

description: Using D2-brane probes, we study various properties of M-theory on singular, non-compact manifolds of G_2 and Spin(7) holonomy. We derive mirror pairs of N=1 supersymmetric three-dimensional gauge theories, and apply this technique to realize exceptional holonomy manifolds as both Coulomb and Higgs branches of the D2-brane world-volume theory. We derive a ``G_2 quotient construction'' of non-compact manifolds which admit a metric of G_2 holonomy. We further discuss the moduli space of such manifolds, including the structure of geometrical transitions in each case. For completeness, we also include familiar examples of manifolds with SU(3) and Sp(2) holonomy, where some of the new ideas are clarified and tested.

description: This study assesses the performance of Botswana's traditional arable agriculture for the 1968-90 period. Growth rate and arable sub-sector production models are specified and estimated to determine how the sub-sector performed over time, and to capture the impact of the Accelerated Rainfed Arable Programme (ARAP). Growth rate model results indicate that cultivated area increased by about 2.2% per year during the 1968-90 period. However, crop output remained unchanged and yields declined by about 6.1% per year during the review period. Sub-sectoral model results reveal that cultivated area, output and yields rose by about 27%, 120% and 74% (respectively) due to the implementation of ARAP. Therefore, ARAP was effective in improving rural household food security and welfare. However, it is further argued that the program was unsustainable since it involved phenomenal government outlays and has led to an unprecedented input substitution from animal traction to tractor traction, which seems to be unjustified given the current economic fundamentals of the country's traditional arable farming. Moreover, the results reveal loss of productivity in the sub-sector over time. Therefore, the challenge facing policy makers is to devise new ways of reversing the current trend. © 1999 Elsevier Science B.V. All rights reserved.

description: La notion d’import/export, volontairement provocatrice, évoque l’histoire des relations internationales au moment de la construction de l’histoire transnationale dans les années 1990. Il s’agissait alors de dépasser la tradition de l’histoire des relations internationales, qui partait des politiques et des États. Toutefois, ne sommes-nous pas allés trop loin en nous éloignant des politiques qui méritent d’être analysées ? Faut-il parler de circulation, d’histoire croisée, de comparaison ? Cette idée d’import-export peut-elle avoir une pertinence ?

description: We derive the two-particle fluctuation correlator in a thermal gas of pi-mesons to the lowest order in an interaction due to a resonance exchange. A diagrammatic technique is used. We discuss how this result can be applied to event-by-event fluctuations in heavy-ion collisions, in particular, to search for the critical point of QCD. As a practical example, we determine the shape of the rapidity correlator.

description: This paper provides an updated review of the evidence on income pooling across household members. Income pooling is one of the main predictions of the unitary model of the household. New studies come to much the same conclusion as do past studies: income pooling and the unitary model are rejected. The paper then looks beyond the mere rejection of the unitary model and explores some of the issues that arise. First, what is the progress in testing the restrictions imposed by non-unitary models of the household? Second, what are the implications of rejection of the unitary model for policy and program design? Finally, what are some of the challenges faced by programs and policies that internalize the rejection of income pooling in terms of impact evaluation? © 1999 Elsevier Science B.V.

Noncommuting Gauge Fields as a Lagrange Fluid

Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The Lagrange description of an ideal fluid gives rise in a natural way to a gauge potential and a Poisson structure that are classical precursors of analogous noncommuting entities. With this observation we are led to construct gauge-covariant coordinate transformations on a noncommuting space. Also we recognize the Seiberg-Witten map from noncommuting to commuting variables as the quantum correspondent of the Lagrange to Euler map in fluid mechanics.

Cosmological Solutions on Compactified AdS_5 with a Thermal Bulk

description: This paper is an investigation of the effects of a thermal bulk fluid in brane world models compactified on AdS_5. Our primary purpose is to study how such a fluid changes the bulk dynamics and to compare these effects with those generated by matter localized to the branes. We find an exact cosmological solution for a thermally excited massless bulk field, as well as perturbative solutions with matter on the brane and in the bulk. We then perturb around these solutions to find solutions for a massive bulk mode in the limit where the bulk mass (m_B) is small compared to the AdS curvature scale and T< m_B. We find that without a stabilizing potential there are no physical solutions for a thermal bulk fluid. We then include a stabilizing potential and calculate the shift in the radion as well as the time dependence of the weak scale as a function of the bulk mass. It is shown that, as opposed to a brane fluid, the bulk fluid contribution to the bulk dynamics is controlled by the bulk mass.

Defining the Topological Influencers and Predictive Principles to Engineer Band Structure of Halide Perovskites

description: Complex quantum coupling phenomena of halide perovskites are examined through ab-initio calculations and exact diagonalization of model Hamiltonians to formulate a set of fundamental guiding rules to engineer the bandgap through strain. The bandgap tuning in halides is crucial for photovoltaic applications and for establishing non-trivial electronic states. Using CsSnI$_3$ as the prototype material, we show that in the cubic phase, the bandgap reduces irrespective of the nature of strain. However, for the tetragonal phase, it reduces with tensile strain and increases with compressive strain, while the reverse is the case for the orthorhombic phase. The reduction can give rise to negative bandgap in the cubic and tetragonal phases leading to normal to topological insulator phase transition. Also, these halides tend to form a stability plateau in a space spanned by strain and octahedral rotation. In this plateau, with negligible cost to the total energy, the bandgap can be varied in a range of 1eV. Furthermore, we present a descriptor model for the perovskite to simulate their bandgap with strain and rotation. Analysis of band topology through model Hamiltonians led to the conceptualization of topological influencers that provide a quantitative measure of the contribution of each chemical bonding towards establishing a normal or topological insulator phase. On the technical aspect, we show that a four orbital based basis set (Sn-$\{s,p\}$ for CsSnI$_3$) is sufficient to construct the model Hamiltonian which can explain the electronic structure of each polymorph of halide perovskites.

description: Access to safe water and sanitation is one of the core development indicators recently gaining pre-eminence in Nigeria. This study examined rural households’ access, willingness to pay (WTP) and factors influencing WTP for safe water and sanitation. The study was conducted in Ogun State, Nigeria. A cross sectional survey which involved the use of questionnaire was used. A dichotomous choice (DC) with follow-up was used as elicitation method. A multi-stage random sampling technique was used to select 160 rural households. Descriptive statistics and Logit regression model was used for data estimation. Results revealed that 24.4% had access to safe water; 21.3% and 6.2% had access to improved toilet and refuse dumping sites. Most respondents showed WTP for these improved services. Sex (p<0.01), occupation (p<0.01) and income (p<0.1) significantly influenced rural households’ likelihood WTP for these facilities. Inference from this study showed that rural dwellers’ access to safe water and sanitation is highly deplorable. Governments and stakeholders should encourage and support to rural people by providing these facilities given their willingness to pay for it.
