description: With the advent of electronic interaction, dominance (or the assertion of control over others) has acquired new dimensions. This study investigates the dynamics and characteristics of dominance in virtual interaction by analyzing electronic chat transcripts of groups solving a hidden profile task. We investigate computer-mediated communication behavior patterns that demonstrate dominance and identify a number of relevant variables. These indicators are calculated with automatic and manual coding of text transcripts. A comparison of both sets of variables indicates that automatic text analysis methods yield similar conclusions than manual coding. These findings are encouraging to advance research in text analysis methods in general, and in the study of virtual team dominance in particular.

description: Smart grids are power grids where clients may actively participate in energy production, storage and distribution. Smart grid management raises several challenges, including the possible changes and evolutions in terms of energy consumption and production, that must be taken into account in order to properly regulate the energy distribution. In this context, machine learning methods can be fruitfully adopted to support the analysis and to predict the behavior of smart grids, by exploiting the large amount of streaming data generated by sensor networks. In this article, we propose a novel change detection method, called ECHAD (Embedding-based CHAnge Detection), that leverages embedding techniques, one-class learning, and a dynamic detection approach that incrementally updates the learned model to reflect the new data distribution. Our experiments show that ECHAD achieves optimal performances on synthetic data representing challenging scenarios. Moreover, a qualitative analysis of the results obtained on real data of a real power grid reveals the quality of the change detection of ECHAD. Specifically, a comparison with state-of-the-art approaches shows the ability of ECHAD in identifying additional relevant changes, not detected by competitors, avoiding false positive detections.

description: We derive a microscopic relativistic point-coupling model of nuclear many-body dynamics constrained by in-medium QCD sum rules and chiral symmetry. The effective Lagrangian is characterized by density dependent coupling strengths, determined by chiral one- and two-pion exchange and by QCD sum rule constraints for the large isoscalar nucleon self-energies that arise through changes of the quark condensate and the quark density at finite baryon density. This approach is tested in the analysis of the equations of state for symmetric and asymmetric nuclear matter, and of bulk and single-nucleon properties of finite nuclei. In comparison with purely phenomenological mean-field approaches, the built-in QCD constraints and the explicit treatment of pion exchange restrict the freedom in adjusting parameters and functional forms of density dependent couplings. It is shown that chiral (two-pion exchange) fluctuations play a prominent role for nuclear binding and saturation, whereas strong scalar and vector fields of about equal magnitude and opposite sign, induced by changes of the QCD vacuum in the presence of baryonic matter, generate the large effective spin-orbit potential in finite nuclei.

description: Conceptual ideas and methodical approaches to the creation of fastplant-technologies for a rapid development and production of niche cultures are formulated in the article for the first time, specifics of their adaptation to the market conditions, adaptation to the conditions of implementation in the system of artificial modular productions placed on the scientific and production basis of cluster unions of the production of competitive niche products. The principles of selecting the components of the fastplant-system, the designation of elements of the modular design of co-production of niche cultures are given. The features of fastplant-technologies, their structure, methodical recommendations for scientific institutions, in relation to the formation of the commercial type technological proposals for introduction into innovative and investment-active segments of the niche market are determined. In this paper the terminology regarding to the concepts definitions of niche cultures, niche products, niche market, results of testing and analysis methods development and forecasting a niche cultures (products) market, creation of a production self-regulation that depends on commercial conditions, social needs state and society based on a market private partnership market system. The seasonal fluctuations of demand for niche crops are analyzed, in this connection the principles of creation a market-oriented technologies and mobile production complexes, which provide conditions for a rapid response to the market demand fluctuations and the deployment of production in the required volumes and quality in the short windows of the off-season, are proposed. It is proved that the main problem of the fastplant-technology creation is that the outgoing scientific developments, which are transforming into selection-technological and industrial innovations, have a low coefficient of a commercial ability. Scientific institutions mostly do not possess market-oriented process methods of creation and promotion competitive scientific and innovative products to consumers. Innovations developed by consulting companies are more adapted to the harsh market conditions, and therefore more understandable to agribusiness. The research presents methodical approaches and regulatory and organizational tools for the preparation of commercial proposals by scientific institutions, on the basis of which the fastplant-technology is created and projects of their use in the science-intensive niche business.

description: We constrain the isotropic luminosity function (LF) and formation rate of long gamma-ray bursts (GRBs) by fitting models 'jointly' to both the observed differential peak flux and redshift distributions. We find evidence supporting an evolving LF, where the luminosity scales as (1+z)^delta with an optimal delta of 1.0\pm 0.2. For a single power-law LF, the best slope is ~ -1.57 with an upper luminosity of 10^53.3 erg/s, while the best slopes for a double power-law LF are approximately -1.6 and -2.6 with a break luminosity of 10^52.7 erg/s. Our finding implies a jet model intermediate between the universal structured epsilon(theta) proportional to theta^-2 model and the quasi-universal Gaussian structured model. For the uniform jet model our result is compatible with an angle distribution between 2 and 15 grades. Our best constrained GRB formation rate histories increase from z=0 to z=2 by a factor of ~30 and then continue increasing slightly. We connect these histories to that of the cosmic star formation history, and compare with observational inferences up to z~6. GRBs could be tracing the cosmic rates of both the normal and obscured star formation regimes. We estimate a current GRB event rate in the Milky Way of ~5 10^-5 yr^-1, and compare it with the birthrate of massive close WR+BH binaries with orbital periods of hours. The agreement is rather good suggesting that these systems could be the progenitors of the long GRBs.

description: In the article we investigate the socio-economic efficiency of land use in agriculture. The peculiarities and tendencies of development of land relations in the conditions of a multi-faceted economy are established. The main indicators of land use efficiency are analyzed: crop yields and gross output of all categories of farms per 100 hectares of agricultural land. The economic and legal aspects of the modern land use in the conditions of the final stage of the reformation of land relations are determined. We analyzed the legal and regulatory framework for land tenure and possession (Law of Ukraine on Land Conservation, Resolution of the Cabinet of Ministers of Ukraine “On Approval of the Norms of Optimal Crop Relations in Crop rotations in Various Natural-Agricultural Regions”, Procedure for the Development of Land Management Projects, Providing Ecological and Economic substantiation of crop rotation and landscaping). We outline the problems of raider seizure of agricultural land. We substantiated the prospects for further transformation of land use in the conditions of the formation of the land market.

description: The scientific view at the restaurant industry which affects on the level of the Ukrainian population food supplying is presented in the research paper. The role of the out of the house meals in improving of the food safety system of Ukraine is shown. Priority economic and organizational tendencies of restaurant business development in Ukraine as the mean of counteraction to the expansion of European brands, producers and suppliers of raw materials were identified. Prospective analysis of state measures which are aimed at activating the formation of Euro-oriented business environment was carried out. It is proved that the gradual bringing of the management principles to European norms already has positive impact on the business climate and creates the necessary conditions for increasing the level of sectoral competitiveness of the national restaurant business enterprises; increasing of investments in this economy sector, in particular, connected with the use of European resources; promotes the intensification of demand for products and services of restaurant enterprises. It is shown that the developed restaurant economy is profitable sector of the country's economy, which, apart from servicing different contingents of consumers and providing them with food services, positions the country profitably on the international market. As the European restaurant business is the most stable in the world, it makes its actual example for national restaurateurs’ imitation. Priority market segments of the out-of-home market for the further development of restaurant business enterprises: medium, medium plus and lower segments with quality improving are identified and it meets the expectations of restaurant audiences where competition intensifying is expected. The complex of progressive competitive forms, formats and popular trends of restaurant business was proposed, the schemes of their adaptation and optimization to the national realities which are aimed at preserving national color and authentic traditions were substantiated for solving of Ukrainian restaurant business applied problems in order to European level achieving.

description: The impressive lifelong learning in animal brains is primarily enabled by plastic changes in synaptic connectivity. Importantly, these changes are not passive, but are actively controlled by neuromodulation, which is itself under the control of the brain. The resulting self-modifying abilities of the brain play an important role in learning and adaptation, and are a major basis for biological reinforcement learning. Here we show for the first time that artificial neural networks with such neuromodulated plasticity can be trained with gradient descent. Extending previous work on differentiable Hebbian plasticity, we propose a differentiable formulation for the neuromodulation of plasticity. We show that neuromodulated plasticity improves the performance of neural networks on both reinforcement learning and supervised learning tasks. In one task, neuromodulated plastic LSTMs with millions of parameters outperform standard LSTMs on a benchmark language modeling task (controlling for the number of parameters). We conclude that differentiable neuromodulation of plasticity offers a powerful new framework for training neural networks.

description: The problem of financial security is especially relevant for enterprises association participants in transition economies, in particular, it concerns agro-industrial companies. The paper is devoted to the study of methods for assessing the level of financial security of enterprises association participants. The purpose of the paper is to apply the methodology for assessing the level of financial security to members of groups of enterprises (which include agro-industrial enterprises), identifying issues and formulating recommendations on the example of «System Capital Management» JSC and «Metinvest Holding» LLC. The modern approaches of scientists to the interpretation of concepts and the use of methods for assessing the level of financial security are analyzed. The method of calculating the integral index of the level of financial security valuation was used and supplemented for the enterprises association participants. The use of integrated assessment indicator of financial security made it possible to identify the poor financial condition of enterprises association members. Suggested ways to achieve a sufficient level of financial security for enterprises association participants based on the research are proposed.

description: This systematic review covers the extant literature on corporate governance in entrepreneurial firms. Using a sample of 137 research papers published from pre-1990 through June 2018 in 60 journals, we categorize outlets, research methods (quantitative, qualitative, review, and non-empirical), theoretical perspectives, and research questions, highlighting key patterns. We then summarize the concepts under study in the sample literature, and the geographical sources and model specification of quantitative empirical studies. The conclusion highlights the quite fragmented nature of the field and the substantial knowledge gaps, and then proposes an actionable agenda for future research in terms of theories, research questions, research settings, and research designs. In particular, we describe the need to explore how corporate governance mechanisms interact with one another and affect firm outcomes, by applying novel theoretical perspectives and methods that could provide a better understanding of entrepreneurial firms’ functioning.

description: We introduce a method to evaluate the steady-state non-equilibrium Keldysh-Schwinger Green's functions for infinite systems subject to both an electric field and a coupling to reservoirs. The method we present exploits a physical quasi-translation invariance, where a shift by one unit cell leaves the physics invariant if all electronic energies are simultaneously shifted by the magnitude of the electric field. Our framework is straightaway applicable to diagrammatic many-body methods. We discuss two flagship applications, mean-field theories as well as a sophisticated second-order functional renormalization group approach. The latter allows us to push the renormalization-group characterization of phase transitions for lattice fermions into the out-of-equilibrium realm. We exemplify this by studying a model of spinless fermions, which in equilibrium exhibits a Berezinskii-Kosterlitz-Thouless phase transition.

description: Ukraine is the largest producer of organic agricultural products in Eastern Europe. The purpose of the paper is to highlight the peculiarities of organic production in Ukraine, its state and development prospects. The dynamics of the area of agricultural lands occupied by organic crops and the number of farms engaged in conducting organic production are analyzed. The structure of agricultural lands certified according to organic standards is presented. The analysis of legal regulation of production of this type of products and development of the market of organic products is carried out. The place of Ukraine in Europe and the world was determined by the area of agricultural crops certified according to organic standards. Organic agriculture creates conditions for ecologically safe land use by preserving and restoring soil fertility, overcoming the negative effects of economic activity on the natural environment. A significant advantage of organic production is substantial contribution to solving food security problems by meeting the needs of the population in safe and high quality food products.
Rank orders and signed interactions in evolutionary biology
Creators: name: Crona, Kristina
Publisher: name: American University
Year: 2023

description: Rank orders have been studied in evolutionary biology for almost a hundred years. Constraints on the order in which mutations accumulate are known from cancer drug treatment, and order constraints for species invasions are important in ecology. However, current theory on rank orders in biology is somewhat fragmented. Here, we show how our previous work on inferring genetic interactions from comparative fitness data (Crona et al., 2017) is related to an influential approach to rank orders based on sign epistasis. Our approach depends on order perturbations that indicate interactions. We apply our results to malaria parasites and find that order perturbations beyond sign epistasis are prevalent in the antimalarial drug-resistance landscape. This finding agrees with the observation that reversed evolution back to the ancestral type is difficult. Another application concerns the adaptation of bacteria to a methanol environment.

description: To address the poor performance of conventional natural gas foam flooding in the tight conglomerate reservoirs of the Mahu region in Xinjiang, a high-activity green material, cellulose nanocrystals (CNC), was introduced to improve foam performance based on a conventional AOS+SDS foam system. However, the impact of CNC on the performance of the conventional foam system and the synergistic effects between CNC and surfactants are not yet clear. Therefore, this study evaluates the improvement effects of CNC on foam performance from both macroscopic and microscopic perspectives by analyzing the foam composite index and the synergistic effects between CNC and surfactants. The study also investigates the factors affecting foam performance and uses a planar visualization model to evaluate the enhanced gas foam flooding effects from a microscopic mechanism perspective. The results indicate that CNC increases the foam composite index by 26,850 mL·min on a macroscopic level. Microscopically, it makes the foam more compact, thickens the foam liquid film by 0.1 mm, improves the wettability reversal by 10%, and reduces the oil-water interfacial tension by 0.26 mN/m. After mixing 1 vol% crude oil, the foam volume and half-life decrease by 12% and 4%, respectively. At reservoir temperature and pressure, the foam volume decreases by 12.7% and 10.5%, but the half-life increases by 4 hours and 3.7 hours, respectively. At formation water mineralization conditions, the foam volume and half-life decrease by 6.6% and 1.7 hours, respectively. In summary, it still has good performance under reservoir conditions. The visualization model demonstrates from a microscopic perspective that the foam system has good gas shutoff capability. After foam flooding, the gas sweep efficiency increases by 54.12%, and the foam flooding and subsequent gas flooding improve the crude oil recovery by 20.32%.

description: We study monetary policy under dierent central bank constitutions when the labor-market insiders set the nominal wage so that the outsiders are involuntarily unemployed. If the insiders are in the ma jority, the representative insider will be the median voter. We show that an independent central bank, if controlled by the median voter, does not produce a systematic in ation bias, albeit equilibrium employment is too low from a social welfare point of view. A dependent central bank, in contrast, is forced by the government to collect seigniorage and to take the government's re-election prospects into account. The predictions of our theory are consistent with the evidence that central bank independence decreases average inflation and inflation variability, but does not affect employment variability.

description: Die Relevanz von Künstlicher Intelligenz (KI) nimmt zu, ebenso wie die diesbezüglichen Sicherheitsbedenken. Dies führt zur Forderung nach einer vertrauenswürdigeren KI, welcher sich Forschende zunehmend annehmen. Es existiert jedoch keine allgemeine Theorie zu Vertrauen in KI; so dient häufig das Modell Trust in Automation von Lee und See (2004) als Forschungsgrundlage, so kann Automation als Basis von KI betrachtet werden. Gleichzeitig wird jedoch in Frage gestellt, ob dieses Modell auf KI übertragen werden kann. Entsprechend wird in dieser Arbeit im Kontext von ChatGPT untersucht, welche Faktoren das Vertrauen in KI beeinflussen und wie sich dies auf die Nutzungsintention auswirkt. Basierend auf Trust in Automation, ergänzt durch die Variable Nutzungsintention, wurde hierzu ein Pfadmodell abgeleitet. Zudem wurden Einflussfaktoren der Neigung zum Vertrauen sowie die zeitliche Veränderung des Zusammenhangs des Vertrauens im Kontext einer Intervention untersucht. Die Datenerhebung erfolgte anhand validierter Fragebögen. Im Rahmen der Datenanalyse wurden die Daten von insgesamt 105 Studierenden berücksichtigt, während für die ergänzende Längsschnittanalyse 10 Datensätze herangezogen wurden. Die Resultate bestätigen das konzeptuelle Pfadmodell nicht, was eine Respezifikation erforderlich machte. Dies hat dazu geführt, dass zusätzliche Pfade von der Neigung zum Vertrauen zu den drei Faktoren der Vertrauenswürdigkeit identifiziert wurden. Das Modell zeigt mit einer Ausnahme die erwarteten positiven Einflüsse. Dabei ist der Einfluss des Vertrauens auf die Nutzungsintention geringer als erwartet. Die Längsschnittanalyse hat keinerlei Veränderungen zwischen den beiden Messzeitpunkten offenbart. Die Ergebnisse unterstützen grösstenteils die Erwartungen, stellen jedoch auch bisherige Annahmen in Frage. So wird Vertrauen möglicherweise eine grössere Rolle zugeschrieben als tatsächlich vorliegt.

description: Animal husbandry is the backbone of the rural economy, many farmers of rural India are depending on the animals’ productivity for their daily income. Their daily bread and need are satisfied by the income of the Animal husbandry activity. Although we are the highest milk producers in the World, the milk yield of the cow in India is very less, so the number of cattle herds available in India is very high. And our Desi cows with because of the low genetic makeup for milk production, are low producers. But if you take Exotic and Crossbred cows, although they have early maturity and high milk yield, there is less disease resistance and more Infertility problems. After the introduction of the Cross Breeding program in India, the Infertility problem has become very high. So, to tackle the Infertility problem many recent reproductive techniques are available, with the reproductive Biologist. So, one such technique is the Estrous Synchronisation program. What is the fixed expectation from an ideal cow? Ideal dairy cows should have aged at puberty -18 months, age at first calving about 30 months, conception date which would have 80%, AI per consumption is 1.3 to 1.7. The calving interval must be 12 to 18 months, it should not exceed beyond this level. Calving to conception must be 60 to 90 days. So, Ideal dairy cows should have all these parameters so that the farmer can get benefit out of rearing the cow. The Delay in consumption rate, after 90 days of parturition, led to the loss of milk production up to 32% loss. Then medicine costs 13%. Calf loss 13%. The added Breeding cost comes around 11%. Then dairy animal maintenance comes to 31%. So, this is how the reproductive parameter, that is infertility causes, heavy economic loss to the farming community.

description: Context: GR290 (M33 V0532=Romano's star) is a luminous M33 object undergoing photometric variability typical for luminous blue variable (LBV) stars. It lies inside Wolf-Rayet region in the Hertzsprung-Russell diagram and possesses a WN8 type spectrum at the light minima. Analysis of Gran Telescopio Canarias (GTC) spectra obtained in 2016 led to the conclusion that it is surrounded by an unresolved HII region formed mostly of ejected material from the central star, and disclosed the presence of a second, more extended asymmetrical emission region. Aims: The aim of this paper is to further explore the structure of the nearby environment of GR290. Methods: Long-slit spectra of GR290 were obtained with three slit orientations in the visual and red spectral regions. The emission-line distribution for each slit was analyzed. Results: We confirm the presence of an asymmetric HII region that extends ~50 pc to the south; ~30pc to the north and southeast; ~20 pc to the east and northwest and ~10pc to the west. We also present the first spectrum to be acquired of a star belonging to the neighboring OB88 association, J013501.87+304157.3, which we classify as a B-type supergiant with a possible binary companion.

description: The merger of binary neutron stars is likely to lead to differentially rotating remnants. In this paper, we survey several cold nuclear equations of state (EOSs) and numerically construct models of differentially rotating neutron stars in general relativity. For each EOS we tabulate maximum allowed masses as a function of the degree of differential rotation. We also determine effective polytropic indices, and compare the maximum allowed masses with those for the corresponding polytropes. We consistently find larger mass increases for the polytropes, but even for the nuclear EOSs we typically find maximum masses 50% higher than the corresponding values for nonrotating (TOV) stars. We evaluate our findings for the six observed binary neutron star (pulsar) systems, including the recently discovered binary pulsar J0737-3039. For each EOS we determine whether their merger will automatically lead to prompt collapse to a black hole, or whether the remnant can be supported against collapse by uniform rotation (possibly as a supramassive star) or differential rotation (possibly as a hypermassive star). For hypermassive stars, delayed collapse to a black hole is likely. For the most recent EOSs we survey the merger remnants can all be supported by rotation against prompt collapse, but their actual fate will depend on the nonequilibrium dynamics of the coalescence event. Gravitational wave observations of coalescing binary neutron stars may be able to distinguish these outcomes -- no, delayed or prompt collapse -- and thereby constrain possible EOSs.

description: The mechanical analog of optical frequency combs, phononic frequency combs, has recently been demonstrated in mechanical resonators and has been attributed to coupling between multiple phonon modes. This paper investigates the influence of mode structure on comb generation using a model of two nonlinearly coupled phonon modes. The model predicts that there is only one region within the amplitude-frequency space where combs exist, and this region is a subset of the Arnold tongue that describes a 2:1 autoparametric resonance between the two modes. In addition, the location and shape of the comb region are analytically defined by the resonance frequencies, quality factors, mode coupling strength, and detuning of the driving force frequency from the mechanical resonances, providing clear conditions for comb generation. These results enable comb structure engineering for applications in areas as broad as sensing, communications, and quantum information science.

description: Rank orders have been studied in evolutionary biology for almost a hundred years. Constraints on the order in which mutations accumulate are known from cancer drug treatment, and order constraints for species invasions are important in ecology. However, current theory on rank orders in biology is somewhat fragmented. Here, we show how our previous work on inferring genetic interactions from comparative fitness data (Crona et al., 2017) is related to an influential approach to rank orders based on sign epistasis. Our approach depends on order perturbations that indicate interactions. We apply our results to malaria parasites and find that order perturbations beyond sign epistasis are prevalent in the antimalarial drug-resistance landscape. This finding agrees with the observation that reversed evolution back to the ancestral type is difficult. Another application concerns the adaptation of bacteria to a methanol environment.

description: Background: Chromosomal deletion involving the 6p25 region results in a clinically recognizable syndrome characterized by anterior eye chamber anomalies with risk of glaucoma and non-ocular malformations (6p25 deletion syndrome). We report a newborn infant case of childhood glaucoma with a combination of partial monosomy 6p25 and partial trisomy 18p11 due to an unbalanced translocation. Materials and methods: The patient was a 0-year-old girl. Both eyes showed aniridia and left eye Peters anomaly with multiple malformations. To identify the chromosomal aberrations in the patient with clinically suspected 6p25 deletion syndrome, we performed cytogenetic analysis (G-banding and multicolor fluorescent in-situ hybridization) and array-based comparative genomic hybridization (array-CGH) analysis. Results: Cytogenetic analyses revealed a derivative chromosome 6 with its distal short arm replaced by an extra copy of the short arm of chromosome 18. Array-CGH analysis detected a 4.6-Mb deletion at 6pter to 6p25.1 and 8.9-Mb duplication at 18pter to 18p11.22. To determine the breakpoint of the unbalanced rearrangement at the single-base level, we performed a long-range PCR for amplifying the junctional fragment of the translocation breakpoint. By sequencing the junctional fragment, we defined the unbalanced translocation as g.chr6:pter_4594783delinschr18:pter_8911541. Conclusions: A phenotype corresponding to combined monosomy 6p25 and trisomy 18p11 presented as childhood glaucoma associated with non-acquired (congenital) ocular anomalies consist of aniridia and Peters anomaly and other systemic malformations. To the best of our knowledge, this is the first report which demonstrated the breakpoint sequence of an unbalanced translocation in a Japanese infant with childhood glaucoma.

description: AI Hya has been known as an eclipsing binary with a monoperiodic $δ$ Sct pulsator. We present the results from its {\it TESS} photometry observed during Sector 7. Including our five minimum epochs, the eclipse timing diagram displays the apsidal motion with a rate of $\dotω$ = 0.075$\pm$0.031 deg year$^{-1}$, which corresponds to an apsidal period of U = 4800$\pm$2000 years. The binary star model represents that the smaller, less massive primary component is 427 K hotter than the pulsating secondary, and our distance of 612$\pm$36 pc is in good agreement with the $Gaia$ distance of 644$\pm$26 pc. We subtracted the binary effects from the observed {\it TESS} data and applied a multifrequency analysis to these residuals. The result reveals that AI Hya is multiperiodic in its pulsation. Of 14 signals detected, four ($f_1$, $f_2$, $f_3$, $f_6$) may be considered independent pulsation frequencies. The period ratios of $P_{\rm pul}/P_{\rm orb}$ = 0.012$-$0.021 and the pulsation constants of $Q$ = 0.30$-$0.52 days correspond to $δ$ Sct pulsations in binaries. We found that the secondary component of AI Hya pulsates in both radial fundamental $F$ modes ($f_2$ and $f_3$) and non-radial $g_1$ modes with a low degree of $\ell$ = 2 ($f_1$ and $f_6$).
