description: We compute the mass and current quadrupole tidal corrections to the four-momentum and energy flux radiated during the scattering of two spinless bodies, at leading order in $G$ and at all orders in the velocities, using the effective field theory worldline approach. In particular, we derive the conserved stress-energy tensor linearly coupled to gravity generated by the two bodies, including tidal fields, and the waveform in direct space. The integral is solved using scattering amplitude techniques. We show that our expressions are consistent with existing results up to the next-to-next-to-leading order in the post-Newtonian expansion.

Spin Screening and Antiscreening in a Ferromagnet/Superconductor Heterojunction

description: We present a theoretical study of spin screening effects in a ferromagnet/superconductor (F/S) heterojunction. It is shown that the magnetic moment of the ferromagnet is screened or antiscreened, depending on the polarization of the electrons at the Fermi level. If the polarization is determined by the electrons of the majority (minority) spin band then the magnetic moment of the ferromagnet is screened (antiscreened) by the electrons in the superconductor. We propose experiments that may confirm our theory: for ferromagnetic alloys with certain concentration of Fe or Ni ions there will be screening or antiscreening respectively. Different configurations for the density of states are also discussed.

description: This paper examines the effect of changes in climatic averages on agricultural production at the national level in Cameroon. The empirical results reveal that Cameroon’s agriculture is influenced by climate variables. The economic value of the projected output in 2050 ranges from USD3.5 billion (41% less than the 1961–2001 mean value at 2.5oC increase in temperature and 8.5% increase in precipitation) to US$ 7.1 billion (18.5% greater than the 1961–2001 mean, for a 1.5°C increase in temperature and a 15% increase in precipitation). A 3.5% increase in temperature associated with a 4.5% increase in precipitation in the absence of irrigation facilities would be detrimental to Cameroon’s agriculture, leading to a loss of almost 46.7% in output value. This would negatively affect the economy as a whole, since close to 30% of Cameroon’s national GDP comes from agriculture.

description: We have examined the effects of 20 keV electron irradiation on [-Cu(1)-O(1)-]n chain oxygen arrangements in oxygen deficient but otherwise twin-free YBa2Cu3O6+x single crystals. Comparison of polarized Raman spectra of non-irradiated and irradiated areas provides evidence that electron bombardments instigate the collective hopping of oxygen atoms either from an interstitial at O(5) site to a vacant O(1) chain site or by reshuffling the chain segments to extend the average length of chains without changing the overall oxygen content. This oxygen ordering effect, while counter-intuitive, is analogous to that found in the photoexcitation induced ordering in which temporal charge imbalance from electron-hole pair creation by inelastic scattering of incident electrons causes a local lattice distortion which brings on the atomic rearrangements.

description: This paper uses a cross-sectional approach to analyze the impacts of climate change on animal husbandry and the way farmers adapt. The study is based on surveys of almost 5000 livestock farmers across ten countries in Africa. A traditional Ricardian regression finds that the livestock net revenues of large farms in Africa are more sensitive to temperature than those of small farms. Cross-sectional analysis also reveals that large farms (but not small farms) have fewer animals per farm in warmer places. Farmers tend to select beef cattle and chickens in cool climates and goats and sheep in hot climates. Using the Ricardian results and examining climate scenarios for 2060 and beyond, the net revenues of small farms are predicted to increase as much as 120% (+USD6 billion) but those of large farms are predicted to fall by 20% (-USD12 billion). The impact estimates in any given period also depend on the rainfall predictions. The results suggest that large livestock farms in Africa are more sensitive to temperature than small ones, primarily because of their dependence on cattle.

description: This study analyzed determinants of farm-level climate adaptation measures in Africa using a multinomial choice model fitted to data from a cross-sectional survey of over 8000 farms from 11 African countries. The results indicate that specialized crop cultivation (mono-cropping) is the agricultural practice most vulnerable to climate change in Africa. Warming, especially in summer, poses the highest risk. It encourages irrigation, multiple cropping and integration of livestock. Increased precipitation reduces the probability of irrigation and will benefit most African farms, especially in drier areas. Better access to markets, extension and credit services, technology and farm assets (labor, land and capital) are critical for helping African farmers adapt to climate change. Government policies and investment strategies must support education, markets, credit and information about adaptation to climate change, including technological and institutional methods, particularly for poor farmers in the dry areas of Africa.
Excluded-volume model for quarkyonic matter II: Three-flavor shell-like distribution of baryons in phase space

description: We extend the excluded-volume model of isospin symmetric two-flavor dense quarkyonic matter [Phys. Rev. C 101, 035201 (2020)] including strange particles and address its implications for neutron stars. The effective sizes of baryons are defined from the diverging hard-core potentials in the short interdistance regime. Around the hard-core density, the repulsive core between baryons at short distances leads to a saturation in the number density of baryons and generates perturbative quarks from the lower phase space, which leads to the shell-like distribution of baryons by the Pauli exclusion principle. The strange-quark Fermi sea always appears at high densities but the $Λ$ hyperon shell only appears when the effective size of the $Λ$ hyperon is smaller than the effective size of nucleons. We find that the pressure of strange quarkyonic matter can be large enough to support neutron stars with two times solar mass and can have a large sound speed, $c_s^2 \simeq 0.7$. The fraction of the baryon number carried by perturbative quarks is about 30% at the inner core of most massive neutron stars.

description: We present the Capodimonte Deep Field (OACDF), a deep field covering an area of 0.5 square degrees in the B, V, R optical bands plus six medium-band filters in the wavelength range 773--913 nm. The field reaches the following limiting AB magnitudes: B~25.3, V~24.8 and R~25.1 and contains about 50000 extended sources in the AB magnitude range 18 < R < 25 . Hence, it is intermediate between deep pencil beam surveys and very wide but shallow surveys. The main scientific goal of the OACDF is the identification and characterization of early-type field galaxies at different look-back times in order to study different scenarios of galaxy formation. Parallel goals include the search for groups and clusters of galaxies and the search for rare and peculiar objects (gravitational lenses, QSOs, halo White Dwarfs). In this paper we describe the OACDF data reduction, the methods adopted for the extraction of the photometric catalogs, the photometric calibration and the quality assessment of the catalogs by means of galaxy number counts, spectroscopic and photometric redshifts and star colors. We also present the first results of the search for galaxy overdensities. The depth of the OACDF and its relatively large spatial coverage with respect to pencil beam surveys make it a good tool for further studies of galaxy formation and evolution in the redshift range 0--1, as well as for stellar studies.

description: Large field surveys of NH3, C2S, 13CO and C18O in the L1551 dark cloud have revealed a prolate, pre-protostellar molecular core (L1551-MC) in a relatively quiescent region to the northwest of the well-known IRS 5 source. The kinetic temperature is measured to be 9K, the total mass is ~2Msun, and the average particle density is 10^4-10^5 cm^(-3). L1551-MC is 2.25' x 1.11' in projection oriented at a position angle of 133deg. The turbulent motions are on the order of the sound speed in the medium and contain 4% of the gravitational energy, E_{grav}, of the core. The angular momentum vector is projected along the major axis of L1551-MC corresponding to a rotational energy of 2.5E-3(sin i)^(-2)|E_{grav}|. The thermal energy constitutes about a third of |E_{grav}| and the virial mass is approximately equal to the total mass. L1551-MC is gravitationally bound and in the absence of strong, ~160 microgauss, magnetic fields will likely contract on a ~0.3 Myr time scale. The line profiles of many molecular species suggest that the cold quiescent interior is surrounded by a dynamic, perhaps infalling envelope which is embedded within the ambient molecular gas of L1551.

description: This paper explores the application of the card-sorting interview technique in understanding the complex interplay of motivations and barriers faced by adults engaging in learning. Traditional research methods, whether quantitative or qualitative, often fail to capture these nuanced interactions or to provide scalable insights for policy development. Card-sorting, which involves sorting and reflecting on physical or virtual cards, offers a middle ground by facilitating deeper reflection and quantification. An empirical study with 69 disadvantaged adult learners highlights the advantages of this technique. Card-sorting enables active engagement, response revision, and comfortable discussion about sensitive issues. It promotes ownership of the results and reduces interview duration while maintaining data depth and richness. Additionally, it balances structured analysis with personal expression flexibility and allows for the quantification of response patterns. The study demonstrates that card-sorting can effectively uncover the interplay of factors influencing adult learning decisions, offering actionable insights for policymakers involved in adult learning. Preliminary findings have already attracted significant interest from policymakers, emphasising the need for refined insights to develop more effective support systems. Future research should explore the feasibility of online card-sorting to enhance scalability and participant comfort.

Different surface bands are identified and classified according to their origin and their response to several structural distortions. We support the, recently proposed [New J. of Phys. 7 (2005) 100], combination of a shear and a Peierls distortions as the origin of the metal-insulator transition. Our results also seem to favor an electronic driving force for the transition.

description: After 10 years, follow up 90’s, number of company’s jump in increase, and so after the fritter of implements, the venture interests decrease continually in the agriculture from 2001. In nation-wide level, correlated to 2000, in 2003 the number of company’s decrease by 7% (6). In the county Intensity of the bad effects of weather (drought, flood) cut down on the increase of agricultural enterprises, also in the future. General cause of the shift ratio between the implements and current assets, which serve the enterprise more than one year, is the subsidence of the rate of resource. Inside the tangible assets the ratio of investments in 4.5%, although in rate equal to tangible assets, it shows more than 60% increase according to 2000. To achieve the investments, the companies use own and foreign source, the latter can feel in the long-term indebtedness. The enterprises have to attend such a craggy increase because it may cause liquidity problems. Enterprises obligated to use their free source toward pay back their obligations (5). For the smooth operation the own liquid sources of enterprises are low (indexes of liquidity and indebtedness) so for finance the operation they need credit and encouragement. Encouragement’s can cause blasts in long term if the effects of these encouragements do not improve the efficiency and do not keep the environment (interest subsidy, guarantee). Joining to the European Union had not get any considerable effect on the development of financial index. Our Union membership impinge on the financial conditions of agriculture enterprises needs a large research.

description: High angular resolution images of IRC +10216 taken at various bandpasses within the near-infrared h, k & l bands are presented. The maps have the highest angular resolution yet recovered, and were reconstructed from interferometric measurements obtained at the Keck 1 telescope in 1997 December and 1998 April, forming a subset of a 7-epoch monitoring program presented earlier [paper 1]. Systematic changes with observing wavelength are found and discussed in context of present geometrical models for the circumstellar envelope. With these new high-resolution, multi-wavelength data and contemporaneous photometry, we also re-visit the hypothesis that the bright compact Core of the nebula (component `A') marks the location of the central carbon star. We find that directly measured properties of the Core (angular size, flux density, color temperature) are consistent with a reddened carbon star photosphere (line-of-sight tau=5.3).

DETERMINE THE KEY FACTORS OF THE AGRARIAN ECONOMIC GROWTH IN THE 21TH CENTURY IN HUNGARY

description: Economic growth is the top economic and political priority of world leaders. Countries with significant rate of development are higher ranked and serve as models for the developing countries and for the economies in transition. As an EU member, Hungary needs to close up the gap also in case of the agriculture. After analysing the period 1994-2004 the major factor among supports influencing growth is investment subsidies ahead of current flow supports such as Supports to reduce the cost of agricultural production. Irrespective of the alternating periods, the gradients established in the statistical analyses and the results from the study of elasticity along the period justify one of the basic tenets of modern economics: in order to achieve the bigger growth, the funds in the form of investments have multiple effects compared to current flow subsidies. In other words, support for the agricultural sector is more effective in the form of investments. Growth formulas for the agricultural sector might be possible with several different approaches and methods; the ones presented in this study are sketches of some of the alternatives. The aim of the research was to identify tendencies and factors that characterise and justify changes in the sector. In the future, agricultural models could arrive at conclusions with well-founded practical implications, which could set agriculture on a path of growth once again. The analysis of the data in the coming years, including the next study of the impact of EU membership, could trace the importance and impact of the factors. Reflecting on the way to the future, investments will continue to have a decisive effect on growth in agriculture. Agricultural output cannot be kept up successfully with the present infrastructure. In order to catch up with the average of the sector in the EU, growth in the GDP through improving efficiency and productivity would be essential, as the present stagnation is due to the low levels in these factors. In order to achieve this aim of increasing the effectiveness, several improvements are necessary: better technology, more favourable basis of production, advances in agrotechnology, hygiene and crop protection, as well as the concentration of land. These aspects should be the priorities for investments and projects. Furthermore, better infrastructure, transportation capacities, maintenance, information and data exchange are necessary for increased efficiency. This direction can be seen in case of 2005 and 2006 and suppose to be continued. As a member of the EU, Hungary faces a fiercer competition in the market, and further being left behind in the field of agriculture has a negative effect on the economy overall.

description: We present an analysis of the Counts-in-Cells (CiC) statistics of subhaloes in the publicly available IllustrisTNG cosmological simulations (TNG100-1, TNG100-3 and TNG300-3), considering their full and dark-only versions, in redshifts ranging from $z = 0$ to $z=5$, and different cell sizes. We evaluated two CiC models: the gravitational quasi-equilibrium distribution (GQED) and the negative binomial distribution (NBD), both presenting good fits, with small detectable differences in the presence of baryons. Scaling and time dependencies of the best-fit parameters showed similar trends compared with the literature. We derived a matter density-in-cells probability distribution function (PDF), associated with the GQED, which was compared to the PDF given in Uhlemann et al. (2016), for the IllustrisTNG 100-3-Dark run at $z=0$. Our results indicate that the simplest gravithermodynamical assumptions of the GQED model hold in the presence of baryonic dissipation. Interestingly, the smoothed (density-in-cells) version of the GQED is also adequate for describing the dark matter one-point statistics of subhaloes and converges, to subpercentage levels (for an interval of parameters), to the Uhlemann et al. PDF in the high density range.

description: Armenian milk marketing cooperatives provide several benefits, of which the increased opportunity for milk marketing is valued most by member farmers. During the cooperative action milk production has also increased due to seminars on cattle feeding, artificial insemination, sanitation programs, and support by cooperatives in feed procurement. Another benefit is that through pooling products of specified grade or quality, marketing cooperatives are better able to market milk to large-scale buyers than individual owners. Putting their efforts together cooperatives can move to distant markets and thus expand their sales opportunities. This is of paramount importance for those cooperatives that have a sole buyer. In addition to milk marketing, almost all of the cooperatives expressed desire to integrate themselves vertically in milk processing with the aim of capturing greater share of the consumers’ food expenditures. It’s worth mentioning that all managers stated the importance of seminars and educational tools to the success of their organizations. However, in their self-assessment lower ratings were noted in the areas of financial management, financial statement analysis, strategic planning, and higher scores were stated for business decision-making and cooperative principles. Our findings indicate that an opportunity exists to reinforce managers’ knowledge in the areas of cooperative principles, division of responsibility between managers and the Board, and financial management. The results of the research come to advocate for continuing cooperative business and extending their activities over other aspects of the agricultural sphere (technical service, agricultural production, etc.), thus enabling farmers to further integrate themselves in food marketing system and improve their incomes.

description: In our research work we have read the domestic and the international professional literature. Based on them and our research work we defined the agricultural technical improvement. The main tasks of the technical improvement of the agriculture in the future are the following: ● Application of the biotechnological achievements. ● Improvement of the environment saving technologies, assurance of the maintainable development of the agriculture, by retaining the production bases – the soil, the biological environment, and the work power of the agricultural workers. ● Adaptation of the precision plant cultivation systems. ● The universal objective of the agrarian-technical improvements is to provide technical base for the maintainable agricultural production. It requires the development of such production technologies, which protect the environment and the landscape, the soil and water reserves, ensure the quality of the product and the economy of the production. ● The development of a coherent system of the electronics, informational technique and automation, the construction of the information network of the agriculture and the transfer of the connected knowledge. The engine of the technical improvement is the continuous investment and the introduction of the new achievements of science as fast as possible. Without investments there is no technical improvement on the merits, but at the same time the investments lead to a proper technical improvement if it is based on a proper economy developing strategy, and if it is coupled with a technical developer and organizer activity. During our researches it was proved that: ● In the analysed time period, in the case of the examined sectors was a great difference between the area’s productivities. ● To measure the partial effectiveness of the production factors the Cobb–Douglas-type production function is good for the examination of the importance of the production factors in the case of a proper data base. The key of promoting the advance is the economical acceleration of the technical progress. The non-recognition of the rate or the characteristics of the technical progress, its improper explanation may lead to great losses. Due to the special importance of the rate of the technical improvement, we need to pay special attention to all circumstances and factors, which boost the technical improvement, make the approach of the world standard possible and the catch-up with its progress. Therefore, we need to take advantage of all opportunities, which are available for us due to our membership in the European Union.

description: The possibility of a vectorlike top partner decaying to a new colourless weak-singlet scalar or pseudoscalar has attracted some attention in the literature. We investigate the production of a weak-singlet charge-$2/3$ $T$ quark that can decay to a spinless boson ($Φ$) and a top quark at the LHC. Earlier, in 2203.13753, we have shown that in a large part of the parameter space, the $T\to tΦ$ and the loop-induced $Φ\to gg$ decays become the dominant decay modes for these particles. Here, we investigate the discovery prospects of the $T$ quark in this region through the above decays. In particular, we focus on the $pp\to TT\to (tΦ)(tΦ)\to (t(gg))\,(t(gg))$ channel. Separating this signal from the huge Standard Model background is a challenging task, forcing us to employ a multivariate machine-learning technique. We find that the above channel can be a discovery channel of the top partner in the large part of the parameter space where the above decay chain dominates. Our analysis is largely model-independent, and hence our results would be useful in a broad class of new physics models.

description: The assumption, that in case of production different from the conventional one, operational and production risk are increasing in farms, is supported by the calculations. Input/output relations undergo a change in each sector and this may have serious financial outcomes, which would importantly determine profit yielding capacity and efficiency of farming. The statement of Offermann and Nieberg is true of the cost structure, according to which essential cost difference between the two technologies can not be measured. By the aid of the calculation, it was successfully verified – in compliance with the opinion of Wookey – that organic production can be as profitable, as the conventional production or even more so. In contradiction to Bmvel’s data, it can be demonstrated, that even a revenues, surpassing the result of conventional production may be realized in organic farms. On the whole, the results obtained strengthen the standing-point of Szente, according to which the profit, originating from organic production may be higher, than that from conventional production, although it fails already to reach the saliently high values, which were characteristic of the earlier years. In production technology, upon the effect of the change in operational elements and elimination of chemical use, increased yield risk is to be taken into account, although at the same time, the possibility of a more successful operation will in-crease through the market premium price. Subsidy of each technology is different, which means, that allowances associated with the expectable future much better environment-saving technologies will further increase profitability. Also market changes may promote this process, since consumers and institutions become increasingly disposed to take a turn to goods, produced free from chemicals. It is indicated also by statistical data, that more and more producers are dealing with organic production and also the size of areas turned on organic farming is continuously increasing. The rhythm of the development of organic markets is still lagging behind this, but the possibility is open to the agricultural sector being in process of transition. Conventional agriculture is yet unable to produce commodities, suitable for satisfaction of all demands of consumers in every respect, and also efficiency and profitability of production are very low, several sectors can be operated with loss only.

description: A search for T-violating transverse muon polarization ($P_T$) in the $K^{+}\to π^{0}μ^{+}ν$ decay was performed using kaon decays at rest. A new improved value, $P_T= -0.0017\pm 0.0023 (stat)\pm 0.0011 (syst)$, was obtained giving an upper limit, $| P_T | < 0.0050$. The T-violation parameter was determined to be Im$ξ= -0.0053 \pm 0.0071(stat)\pm 0.0036(syst)$ giving an upper limit, $|$Im$ξ| <0.016$.

On the Production of Open Strings from Brane Anti-Brane Annihilation

description: We investigate the leading contribution to open string production in the time dependent background of the Brane Anti-Brane. This is a 1-loop diagram and we use Boundary Conformal Field Theory (BCFT) techniques to study it. We show that the amplitude to a single open string naively diverges when one looks at it as an expansion in oscillator levels. Nevertheless, we show that once we sum over all oscillator levels we get a finite result. We also clarify where to perform the inverse Wick rotation in this kind of problems. This calculation could have important consequences for the theory of reheating in brane inflationary models.

description: We couple a sterile neutrino sector to a spin-3/2 particle and show that with a Planck reduced coupling, we can obtain a sufficiently long lifetime making the spin-3/2 particle a good dark matter candidate. We show that this dark matter candidate can be produced during inflationary reheating through the scattering of Standard Model particles. The relic abundance as determined by Planck and other experimental measurements is attained for reasonable values of the reheating temperature $T_{\rm RH} \gtrsim 10^{8}$ GeV. We consider two possible gauge invariant couplings to the extended Standard Model. We find a large range of masses are possible which respect the experimental limits on its decay rate. We expect smoking-gun signals in the form of a monochromatic photon with a possible monochromatic neutrino, which can be probed in the near future in IceCube and other indirect detection experiments.

description: The perfect segregation of the different agricultural production types, namely conventional, organic or based on genetically modified organisms is not possible in practice. But the side by side functioning of this systems in agricultural production and further on of the products on the shelves requires suitable measures during cultivation, harvest, transport, storage, and processing to ensure co-existence. Consumers, food and feed industry, as well as wholesalers and retailers in European Union, including Polish ones demand a reasonable degree of choice between GMO and non-GMO derived products. Accordingly the ability to maintain different agricultural production and processing systems is a pre-requisite for providing a high degree of consumer choice. As the organic production grows in Poland and on other hand there is observed increase of the GMO importance in food and feed chains the rivalry between organic and GMO sector rises and the competition between products coming from this sectors is increasing on the market too. What are then, the advantages of organic sector that qualifies them over GMO competitors and might constitute as a basis for the competitive strategy? This is the perception of organic products by the consumers, which is much favorable comparing to GMO. Then the developing organic sector increases the availability of organic products and forces the competition to provide products meeting consumers requirements. Finally low capital requirements, subsidies and opportunities for market increase gives organic sector in Poland an unique advantage to expand not only domestically but also abroad. A key factor in the competitive strategy of the organic sector should be therefore the broad information about the advantages of organic nutrition. The advertising and sale forces, which are elements of the communication with the consumers, would be appreciable contributors to organic sector’s development, and accordingly threat to GMO products. In this context the co-existance brings the biggest results to the economic and market issues, placing the consumer attitude as a key factor for development of the market competitive advantages, especially for organic sector in Poland.

description: Universal scaling of distances between vertices of Erdos-Renyi random graphs, scale-free Barabasi-Albert models, science collaboration networks, biological networks, Internet Autonomous Systems and public transport networks are observed. A mean distance between two nodes of degrees k_i and k_j equals to =A-B log(k_i k_j). The scaling is valid over several decades. A simple theory for the appearance of this scaling is presented. Parameters A and B depend on the mean value of a node degree _nn calculated for the nearest neighbors and on network clustering coefficients.

description: The payment amount of the entry level scheme significantly exceeds the additional costs which arise from abiding by the regulations and with this the financial situation and competitiveness of the viable agricultural enterprises may improve. Based on the pre-calculation in relation to the fortuituos entry into the integrated target scheme it can be concluded that the additional cost determined by the target scheme would only use up just about half of the surplus payment allotted through the integrated target scheme. It is well-worth to make use of the opportunities given by these schemes, because through them the enterprise can obtain a regular, secure and significant income.

description: We construct embeddings of Bers slices of ideal polygon reflection groups into the classical family of univalent functions $Σ$. This embedding is such that the conformal mating of the reflection group with the anti-holomorphic polynomial $z\mapsto\overline{z}^d$ is the Schwarz reflection map arising from the corresponding map in $Σ$. We characterize the image of this embedding in $Σ$ as a family of univalent rational maps. Moreover, we show that the limit set of every Kleinian reflection group in the closure of the Bers slice is naturally homeomorphic to the Julia set of an anti-holomorphic polynomial.
