description: Ten countries that have joined the European Union in 2004, had a chance to use EU rural development instruments for support of establishment new producer groups of agricultural producers between 2004 and 2006. Both analysed countries (Czech Republic and Slovakia) have used the opportunity and co-financed programme that aimed on supporting establishment and alleviation of administrative burden. Main aim of the article is to compare conditions and outcomes of the programmes in the Czech Republic and Slovakia and to propose programme innovations. The article describes theoretical assumptions, compares legislative background in selected countries, measures amount of support available and compares outcomes of newly established groups after receiving last supporting payment. One of the conclusions finds Slovak approach more effective. Lower number of supported groups and different conditions result in higher share of successful organisations, higher average revenues of supported groups and higher proportion of revenues in relation to total output of agricultural industry. Finally there are proposed recommendations for the Czech Republic, how programme conditions should be innovated. The article originated as a part of the Internal Grant Agency (IGA) of the Czech University of Life Sciences Prague, Registration Number 20121077.

description: We develop a formalism to carry out coarse-grainings in quantum field theoretical systems by using a time-dependent projection operator in the Heisenberg picture. A systematic perturbative expansion with respect to the interaction part of the Hamiltonian is given, and a Langevin-type equation without a time-convolution integral term is obtained. This method is applied to a quantum field theoretical model, and coupled transport equations are derived.

description: SHiP is a proposed high-intensity beam dump experiment set to operate at the CERN SPS. It is expected to have an unprecedented sensitivity to a variety of models containing feebly interacting particles, such as Heavy Neutral Leptons (HNLs). Two HNLs or more could successfully explain the observed neutrino masses through the seesaw mechanism. If, in addition, they are quasi-degenerate, they could be responsible for the baryon asymmetry of the Universe. Depending on their mass splitting, HNLs can have very different phenomenologies: they can behave as Majorana fermions -- with lepton number violating (LNV) signatures, such as same-sign dilepton decays -- or as Dirac fermions with only lepton number conserving (LNC) signatures. In this work, we quantitatively demonstrate that LNV processes can be distinguished from LNC ones at SHiP, using only the angular distribution of the HNL decay products. Accounting for spin correlations in the simulation and using boosted decision trees for discrimination, we show that SHiP will be able to distinguish Majorana-like and Dirac-like HNLs in a significant fraction of the currently unconstrained parameter space. If the mass splitting is of order $10^{-6}$ eV, SHiP could even be capable of resolving HNL oscillations, thus providing a direct measurement of the mass splitting. This analysis highlights the potential of SHiP to not only search for feebly interacting particles, but also perform model selection.

description: The agricultural education covers all levels of formal education but focuses mostly on the higher ones as well as the vocational education and training. Online courses play an important role in the educational context and compared to traditional courses they eliminate the location and time restrictions and allow a self-paced attendance of a curriculum. At the same time, the existence of online courses raised the need for the design and implementation of the appropriate platforms which may be used for the organization and deployment of online courses. This paper presents the case of agriMoodle, a course management platform based on the widely used Moodle platform, which provides a number of enhancements in the form of modules or widgets specialized for the agricultural domain. These modules aim to enhance the user experience and the functionalities of a standard Moodle installation.
A model scaffold for Anterior Cruciate Ligament (ACL) tissue engineering
Creators: name: Chiera, Silvia
Publisher: name: Università degli studi di Trento
Year: 2021

description: Ligament/tendon disorders and injuries are among the most common health problem influencing the adult and sport population. Anterior cruciate ligament (ACL), is one of the ligaments most injured in the knee, and the soft-to-hard tissue integration (enthesis) shows high rupture rates. To overcome problems related to therapies currently used in medical practice, tissue engineering (TE) has recently emerged as an alternative strategy. TE is a field that applies principles of biology, engineering and medicine toward the development of biological tissue substitutes to restore, repair or improve damaged tissues. Ligament/tendon TE focuses on the combination of specific cell types with a biodegradable scaffold. Once implanted, the scaffold has gradually to degrade, while the tissue is regenerating. The scaffold should be able to promote cell adhesion, differentiation, proliferation and extracellular matrix (ECM) production. Different scaffold materials have been successfully studied for TE application, and among them, silk fibroin has emerged as a promising one. In this work, silk fibroin has been used to fabricate a ligament scaffold comprising the ligamentous part and the enthesis. The enthesis was fabricated with fibroin sponges with a region of anisotropic porosity (ligament site) and a region of isotropic porosity (bone site). The enthesis construct was functionalized with heparin molecules to increase the growth factors affinity. Specifically, the effects of TGF-β2 and GDF5 combined with the structural features of the scaffold led to differentiation of AdMSCs. The alignment of the pores and the biological cues synergistically influenced the gene expression and the protein expression. In fact, the tendon/ligament markers were promoted in the anisotropic part of the construct, as well as the cartilage and the enthesis markers in the isotropic and transition part, respectively. The central part of the ligament was realized with a composite of silk fibroin yarns in a spongeous matrix of silk fibroin, where the yarns have the role to sustain the applied load and the fibroin sponge the role of allowing cell penetration, organization and ECM production. The amount of yarns was decided on the basis of the reported loading of the ligament scaffold after a surgery and during rehabilitation. A homemade perfusion bioreactor was used to evaluate cell penetration and activity in the scaffold. It was proven that cell culture perfusion stimulation induced cells to populate the model scaffold and to produce ECM components, especially with the presence of TGF-β2 growth factor, indicating the starting point of the regeneration process. Additionally, animal studies have been performed and the inflammatory response was evaluated. Even if not final, the results indicate that the above strategy could be explored for the fabrication of a full ligament TE scaffold able to bear the physiological loads until the ligament regenerates.
The Explosion of Helium Stars Evolved With Mass Loss

description: Light curves, explosion energies, and remnant masses are calculated for a grid of supernovae resulting from massive helium stars that have been evolved including mass loss. These presupernova stars should approximate the results of binary evolution for stars in interacting systems that lose their envelopes close to the time of helium core ignition. Initial helium star masses are in the range 2.5 to 40\,\Msun, which correspond to main sequence masses of about 13 to 90\,\Msun. Common Type Ib and Ic supernovae result from stars whose final masses are approximately 2.5 to 5.6\,\Msun. For heavier stars, a large fraction of collapses lead to black holes, though there is an island of explodability for presupernova masses near 10\,\Msun. The median neutron star mass in binaries is 1.35--1.38\,\Msun \ and the median black hole mass is between 9 and 11\,\Msun. Even though black holes less massive than 5 \Msun\ are rare, they are predicted down to the maximum neutron star mass. There is no empty ``gap'', only a less populated mass range. For standard assumptions regarding the explosions and nucleosynthesis, the models predict light curves that are fainter than the brighter common Type Ib and Ic supernovae. Even with a very liberal, but physically plausible increase in $^{56}$Ni production, the highest energy models are fainter, at peak, than 10$^{42.6}$\,erg\,s$^{-1}$, and very few approach that limit. The median peak luminosity ranges from 10$^{42.0}$ to 10$^{42.3}$\,erg\,s$^{-1}$. Possible alternatives to the standard neutrino-powered and radioactive-illuminated models are explored. Magnetars are a promising alternative. Several other unusual varieties of Type I supernovae at both high and low mass are explored.

The source data for the paper were gathered in the survey among agricultural enterprises from various regions of the Czech Republic. There are results of the survey and the overview of the current state of the use of business informatics is described here. Main findings are that it is the owner of the farm who mostly works with business informatics and for most of them the informatics is a necessary technological solution. The investments in farms are currently directed to mobile hardware equipment. Most frequently used programs are accounting information systems, stock control and specialized programs for plant production and livestock.

description: The production of quantum entanglement between weakly coupled mapping systems, whose classical counterparts are both strongly chaotic, is investigated. In the weak coupling regime, it is shown that time correlation functions of the unperturbed systems determine the entanglement production. In particular, we elucidate that the increment of nonlinear parameter of coupled kicked tops does not accelerate the entanglement production in the strongly chaotic region. An approach to the dynamical inhibition of entanglement is suggested.

description: Maize is a major staple crop in Ghana which needs to be produced optimally towards food security and commercialization. In relation to this the study adopts the stochastic frontier model to analyze technical efficiency of maize farms in the Brong Ahafo Region of Ghana using a cross sectional data of 232 farms. The findings demonstrate that the input variables scaled per hectare: seed, herbicide, labor and cost of intermediate input influence maize output positively at a decreasing returns to scale. The study further finds that maize producers realize 83% of the frontier output averagely and there is the possibility to increase maize output by 17% at the given technology and input levels in the short run through the adoption of the best farm practices. The study concludes that producer specific factors impede the full potential of the farmers and the inefficiency effects can be mitigated by focusing on policies that enhances the use of best farm practices.

description: Spin pumping is a widely recognized method to generate the spin current in the spintronics, which is acknowledged as a fundamentally dynamic process equivalent to the spin-transfer torque. In this work, we theoretically verify that the oscillating spin current can be pumped from the microwave-motivated breathing skyrmion. The skyrmion spin pumping can be excited by a relatively low frequency compared with the ferromagnetic resonance (FMR) and the current density is larger than the ordinary FMR spin pumping. Based on the skyrmion spin pumping, we build a high reading-speed racetrack memory model whose reading speed is an order of magnitude higher than the SOT (spin-orbit torque) /STT (spin-transfer torque) skyrmion racetrack. Our work explored the spin pumping phenomenon in the skyrmion, and it may contribute to the applications of the skyrmion-based device.

description: We propose a novel equation of state (EoS) which explains the evolutionary history of a flat Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe. The uniqueness of this EoS lies in the fact that it incorporates the Lambert $W$ function in a special fashion. It is explicitly demonstrated that with observationally relevant values of the unknown parameters $\vartheta_\mathrm{1}$ and $\vartheta_\mathrm{2}$, all the evolutionary phases of the Universe can be reproduced. Moreover, it also shows that the initial singularity is unavoidable and asserts that the late-time acceleration of the Universe would continue forever.

description: In this work, we propose a framework to store and manage spatial data, which includes new efficient algorithms to perform operations accepting as input a raster dataset and a vector dataset. More concretely, we present algorithms for solving a spatial join between a raster and a vector dataset imposing a restriction on the values of the cells of the raster; and an algorithm for retrieving K objects of a vector dataset that overlap cells of a raster dataset, such that the K objects are those overlapping the highest (or lowest) cell values among all objects. The raster data is stored using a compact data structure, which can directly manipulate compressed data without the need for prior decompression. This leads to better running times and lower memory consumption. In our experimental evaluation comparing our solution to other baselines, we obtain the best space/time trade-offs.

description: Excitonic properties in the Kagome lattice system, which is produced by quantum wires on semiconductor surfaces, are investigated by using the exact diagonalization of a tight binding model. It is shown that due to the existence of flat bands the binding energy of exciton becomes remarkably large in the two-dimensional Kagome lattice compared to that in one-dimensional lattice, and the exciton Bohr radius is quite small as large as a lattice constant. We also discuss the magnetic field effects on the exciton binding energy and the stability of exciton against the creation of charged exciton and biexciton.

description: One of the major benefits of belonging to a prestigious group is that it affects the way you are viewed by others. Here I use a simple mathematical model to explore the implications of this "prestige bias" when candidates undergo repeated rounds of evaluation. In the model, candidates who are evaluated most highly are admitted to a "prestige class", and their membership biases future rounds of evaluation in their favor. I use the language of Bayesian inference to describe this bias, and show that it can lead to a runaway effect in which the weight given to the prior expectation associated with a candidate's class becomes stronger with each round. Most dramatically, the strength of the prestige bias after many rounds undergoes a first-order transition as a function of the precision of the examination on which the evaluation is based.

Non-Commutative space: boon or bane for quantum engines and refrigerators

Publisher: name: arXiv

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Various quantum systems are considered as the working substance for the analysis of quantum heat cycles and quantum refrigerators. The ongoing technological challenge is how efficiently can a heat engine convert thermal energy to mechanical work. The seminal work of Carnot has proposed a fundamental upper limit-the Carnot limit on the efficiency of the heat engine. However, the heat engines can be operated beyond the fundamental upper limit by exploiting non-equilibrium reservoirs. Here, the change in the space structure introduces the non-equilibrium effect. So, a question arises whether a change in the space structure can provide any boost for the quantum engines and refrigerators. The efficiency of the heat cycle and the coefficient of performance (COP) of the refrigerator cycles in the non-commutative space are analyzed here. The efficiency of the quantum heat engines gets a boost with the change in the space structure than the traditional quantum heat engine but the effectiveness of the non-commutative parameter is less for the efficiency compared to the COP of the refrigerator. There is a steep boost for the coefficient of performance of the refrigerator cycles for the non-commutative space harmonic oscillator compared to the harmonic oscillator.

description: The Ghana School Feeding Programme is the local version of the Home Grown School Feeding. Launched in 2005, the programme has three basic objectives; Poverty Reduction and Food Security, Reducing Hunger and Malnutrition and Boosting Domestic Food production in Ghana. Studies have shown that the programme have had tremendous impact on school enrolment, retention and malnutrition but the same cannot be said about its agricultural portfolio. Indications are that the programme has not succeeded in boosting domestic food production. Over the years no clear procurement procedures relating to the purchase of foodstuff have been followed. Linkage between the Ghana School Feeding Programme and local farmers is a subject matter that is under-researched. This study therefore seeks to assess the factors that influence Ghana School Feeding Programme caterers to buy rice from local farmers in the Tamale metropolis, Tolon-Kumbungu and Karaga districts of the northern of Ghana. The findings will be useful to policy makers and rice farmers in generally especially with regard to agricultural marketing opportunities created by the School Feeding Programme. Analysis of the Ghana School Feeding Programme’s procurement of rice from local farmers was conducted using a probit regression model. The willingness of caterers to buy rice from the local farmer which is a binary choice is the dependent variable and the factors which are hypothesized to influence the decision of the caterer are the independent variables. The results show that majority of caterers buy rice from local millers and the market and very little from local farmers. The factors which had significant influence on the caterers to buy from the local rice farmer include, availability of storage facility, other jobs done by caterers, price of milled rice, easy location of rice farmers and delays in the payment of feeding bursaries. The Ghana School Feeding Programme Secretariat should employ caterers who are unemployed and do not have any other jobs doing. Also the provision of adequate storage facilities in schools and the early disbursement of feeding bursaries to caterers are essential in solving the problem of buying foodstuffs directly from farmers.
title: Pharmacological Investigation of Nox2-NADPH Oxidase Inhibitors and p47phox Redox-signalling in Angiotensin II-induced Cardiac Hypertrophy in Mice
Creators: name: Liu, Fangfei
Publisher: name: University of Reading
Year: 2023

description: Reactive oxygen species (ROS) are involved in the signal transduction and cell defence in mammalian cells. However, excessive ROS derived under pathophysiological conditions are associated with the development of a wide range of diseases including cardiovascular, metabolic, neurodegenerative diseases and cancer. gp91phox -containing NADPH oxidase (Nox2) was found to be one of the primary enzymatic sources of ROS and p47phox is its key regulator. LMH001 was developed in this lab as an inhibitor of Nox2 targeting p47phox , but its chemical properties and preclinical pharmacokinetics and pharmacodynamics (PK/PD) have not been studied. At the same time, the role of p47phox and its signalling pathways under pathophysiological conditions remained unclear. Therefore, the overall aim of this study is to characterise the PK/PD properties of LMH001 and understand its mechanism in depth by knockout (KO) of p47phox in Angiotensin II (AngII)-induced oxidative stress and cardiac hypertrophy model. The plasma concentration of LMH001 showed a mono-exponential decline pattern with a t1/2 = 0.042 h and a clearance = 5682.63 mL/h/kg, and its effect in reducing AngII-stimulated H9C2 (a rat myoblast cell line) ROS production showed an IC50 = 124.00 ± 42.6 ng/ml. In the AngII-induced hypertrophic models, wild type (WT) mice displayed significantly raised systolic blood pressure (SBP) and induced cardiac hypertrophy after AngII-infusion. In contrast, p47phox KO mice only demonstrated a mild increase in SBP without hypertrophy. There was also phosphorylation of ERK1/2, p38 MAPK and MAPK kinase 3/6 (MKK3/6). Apoptosis was suggested by increased levels of H2AX and apoptosis signal-regulating kinase 1 (ASK1) phosphorylation. In conclusion, p47phox plays a crucial role in AngII-induced cardiac oxidative stress and hypertrophy. Its signalling through MKK3/6, p38MAPK and ERK1/2 phosphorylation are essential in H2AX and ASK1 phosphorylation and cardiomyocyte apoptosis. This study also provided vital information on the chemical properties, PK/PD, and pharmacological efficacy of LMH001. Its potential as a drug candidate for oxidative stress-related diseases was discussed, and future experiments on the development of LMH drugs were suggested.

It takes into account the equilibrium positions of electrons in a Wigner cluster to minimize the interaction energy in the high field limit. Assuming perfect spin alignment the many-body trial function is a single Slater determinant of overlapping oscillator functions from the lowest Landau level centered at and near the classical equilibrium positions. We obtain an analytic expression for the ground state energy and present numerical results for up to N=40.

description: Based on the assumption that needs play a key role in adoption behaviour, it is hypothesised that especially economic incentives, or a lack thereof, are of critical importance in explaining behaviour concerning recommended veld management systems. The perceived incompatibility of improved veld management with economic aspirations and goals and the doubts concerning production advantages and overall profitability, support the hypothesis and suggest that a strengthening of change-conducive or positive forces is more likely to bring about change than a reduction of negative forces.

description: The Ensemble Kalman Filter method can be used as an iterative particle numerical scheme for state dynamics estimation and control--to--observable identification problems. In applications it may be required to enforce the solution to satisfy equality constraints on the control space. In this work we deal with this problem from a constrained optimization point of view, deriving corresponding optimality conditions. Continuous limits, in time and in the number of particles, allows us to study properties of the method. We illustrate the performance of the method by using test inverse problems from the literature.

The Role of Non-Governmental Organizations (NGOs) in the Socio-Economic Development Process: People's Participation as the Key

description: The main theme of this symposium is "Agricultural Restructuring in Southern Africa". Seeking for a topic which has priority and which is - in the view of the author - an integral part of this theme, this paper addresses the role of non-governmental organizations in the socio-economic development process with people's participation as the key. This institutional approach is closely interrelated with land use and efficiency small farmer support programs the design of development projects institutions and public choice theory a self-reliance approach at individual as well as regional/national/international level. All these points are linked with the crucial and challenging problem: How to overcome the absolute poverty in the developing world by using the existing potentialities of human and natural resources - supported by people's mutual help which is organized in their private voluntary institutions and fostered by a macroeconomic political frame with positive external effects for an active "development from the bottom". Due to the fact that absolute poverty is mainly concentrated in rural areas, which also leads to sharp migration and the problem of over-agglomeration of cities, the paper deals above all with this regional problem and with the challenging approach to contribute to an adequate solution through so-called "integrated rural development". The paper presents a frame in which empirical investigations of Southern Africa can be integrated.
Scaling theory for two-dimensional single domain growth driven by attachment of diffusing adsorbates

description: Epitaxial growth methods are a key technology used in producing large-area thin films on substrates but as a result of various factors controlling growth processes the rational optimization of growth conditions is rather difficult. Mathematical modeling is one approach used in studying the effects of controlling factors on domain growth. The present study is motivated by a recently found scaling relation between the domain radius and time for chemical vapor deposition of graphene. Mathematically, we need to solve the Stefan problem; when the boundary moves, its position should be determined separately from the boundary conditions needed to obtain the spatial profile of diffusing adsorbates. We derive a closed equation for the growth rate constant defined as the domain area divided by the time duration. We obtain approximate analytical expressions for the growth rate; the growth rate constant is expressed as a function of the two-dimensional diffusion constant and the rate constant for the attachment of adsorbates to the solid domain. In experiments, the area is decreased by stopping the source gas flow. The rate of decrease of the area is obtained from theory. The theoretical results presented provide a foundation to study controlling factors for domain growth.

Analytical amplitudes from numerical solutions of the scattering equations

description: The CHY formalism for massless scattering provides a cohesive framework for the computation of scattering amplitudes in a variety of theories. It is especially compelling because it elucidates existing relations among theories which are seemingly unrelated in a standard Lagrangian formulation. However, it entails operations that are highly non-trivial to perform analytically, most notably solving the scattering equations. We present a new Python package ( https://github.com/GDeLaurentis/seampy ) to solve the scattering equations and to compute scattering amplitudes. Both operations are done numerically with high-precision floating-point algebra. Elimination theory is used to obtain solutions to the scattering equations for arbitrary kinematics. These solutions are then applied to a variety of CHY integrands to obtain tree amplitudes for the following theories: Yang-Mills, Einstein gravity, biadjoint scalar, Born-Infeld, non-linear sigma model, Galileon, conformal gravity and $(\text{DF})^2$. Finally, we exploit this high-precision numerical implementation to explore the singularity structure of the amplitudes and to reconstruct analytical expressions which make manifest their pole structure. Some of the expressions for conformal gravity and the $(\text{DF})^2$ gauge theory are new to the best of our knowledge.

description: We analyze the efficiency of organic pasture farming in Germany using data from 1994/95 to 2005/06. Five inputs and one output are analyzed by means of a stochastic frontier production function, allowing for heteroscedasticity and technical effects. Five sets of possible determinants of technical efficiency are considered in the model. These include: (1) farm structure and resources; (2) human capital and management capacities; (3) institutional choice; and (4) subsidies. To these factors that are commonly included in technical effects models, we add (5) a set of variables that capture localization and urbanization economies such as the share of organic farms in a region and the regional share of votes for the Green Party in recent elections. These regional effects are found to have a significant impact on the technical efficiency of organic farms. The evolution of efficiency on farms that are converting from conventional to organic farming is also analyzed.

Algebraic Approach to q,t-Characters

Publisher: name: arXiv

description: Frenkel and Reshetikhin introduced q-characters to study finite dimensional representations of quantum affine algebras. In the simply laced case Nakajima defined deformations of q-characters called q,t-characters. The definition is combinatorial but the proof of the existence uses the geometric theory of quiver varieties which holds only in the simply laced case. In this article we propose an algebraic general (non necessarily simply laced) new approach to q,t-characters motivated by our deformed screening operators. The t-deformations are naturally deduced from the structure of the quantum affine algebra: the parameter t is analog to the central charge c. The q,t-characters lead to the construction of a quantization of the Grothendieck ring and to general analogues of Kazhdan-Lusztig polynomials in the same spirit as Nakajima did for the simply laced case.
