description: We consider finite-temperature $SU(2)$ gauge theory in the continuum formulation. Choosing the Landau gauge, the existing gauge copies are taken into account by means of the Gribov-Zwanziger quantization scheme, which entails the introduction of a dynamical mass scale (Gribov mass) directly influencing the Green functions of the theory. Here, we determine simultaneously the Polyakov loop (vacuum expectation value) and Gribov mass in terms of temperature, by minimizing the vacuum energy with respect to the Polyakov-loop parameter and solving the Gribov gap equation. The main result is that the Gribov mass directly feels the deconfinement transition, visible from a cusp occurring at the same temperature where the Polyakov loop becomes nonzero. Finally, problems for the pressure at low temperatures are reported.

description: The aim of the paper was to assess the profit efficiency in representative farms in FADN regions operating in various types of agriculture. For this purpose, clusters of FADN regions with relatively similar dominant types of agriculture were selected on the basis of their partial productivity indicators. Then, efficiency indicators were calculated for each region, using various types of DEA models. The data were adapted from FADN and covered the 2004 and 2015 period. On the basis of analysis conducted in the article, it was found that the farms located in Mediterranean regions were the most efficient. At the same time, in the cluster covering the regions with the most modern agriculture, the efficiency was at a very low level. Farms in most regions operated under the conditions of decreasing economies of scale, although the efficiency of scale itself improved. Moreover, in contrast to 2004, an increase in efficiency in relation to the best practice frontier was observed in 2015.

description: New extra series of conserved densities for the polytropic gas model and nonlinear elasticity equation are obtained without any references to the recursion operator or to the Lax operator formalism. Our method based on the utilization of the symmetry operators and allows us to obtain the densities of arbitrary homogenuity dimensions. The nonpolynomial densities with logarithmics behaviour are presented as an example. The special attention is paid for the singular case $(γ=1)$ for which we found new non homogenious solutions expressed in terms of the elementary functions.

description: We have investigated the nucleation of superconductivity in an Al mesoscopic disk, with a magnetic dot on the top. The dot is magnetized perpendicularly, and its magnetic field is inhomogeneous. The Al disk and magnetic dot are separated by an insulating layer, which ensures that there is only magnetic interaction between them. This hybrid superconductor/ferromagnet structure exhibits the maximum critical temperature for a finite value of the perpendicular applied magnetic field, which is parallel to the magnetization of magnetic dot. We have found a good agreement between the experimental data for the superconductor/normal metal phase boundary and the theoretical predictions based on the Ginzburg-Landau theory.

description: Newly synthesized 4-substituted phenyl-2-(4-substituted phenylpiperazine-1-yl)thiazole derivatives (4a–v) were evaluated in terms of their acetylcholinesterase (AChE) inhibition activities. Twenty-two compounds were tested against AChE at six different concentrations that varied between 10−4 and 10−9 M. The concentrations that inhibited AChE were calculated between 1.15 and 3.45 µM in seven compounds (4a, 4b, 4h, 4l, 4m, 4q, 4r). Compounds 4m, 4b, and 4l represented 1.15, 1.31, 1.34 µM (IC50) inhibitions, respectively. Although the inhibition values are lower than that of donepezil, they are considerable. Modeling studies of these analogs revealed similar positioning with donepezil, in which Ar–Ar interactions with Tyr337 and Trp 286 exist.

description: "Cuando el macho cabrío beba las aguas turbulentas de Neda, abandonaré Mesene; la destrucción llegará." Oráculo de Delfos: Tras la batalla en la que los arcadios fueron sobornados, los mesenios fueron a Delfos en busca de un oráculo. La sacerdotisa pitia profetizó:
En medio de un wayu con Esparta, los mesenios, por supuesto, temían que un macho cabrío se acercara a Neda. Existe una higuera silvestre llamada olynthe, a la que los mesenios llaman «macho cabrío». El profeta mesenio, Teocles, descubrió con horror una higuera silvestre que había crecido sobre el río Neda y cuyas hojas tocaban el agua, y comprendió su significado. Teocles informó a Aristómenes, quien lo tomó muy en serio. Aunque creía que el fin estaba cerca, Aristómenes y Teocles lo mantuvieron en secreto. Según el folclore, había un pastor laconio que se había enamorado de una mesenia en Eira. Siempre que su esposo estaba de guardia, se colaba en la casa para hacerle el amor. En la noche de una terrible tormenta con lluvia torrencial, y mientras Aristómenes yacía en el suelo herido, los guardias decidieron refugiarse de la tormenta. El pastor, al darse cuenta de que Eira estaba indefensa por el momento, escapó y acudió al general laconio, quien inmediatamente lanzó un ataque y logró entrar en la ciudad. La lucha fue feroz. Los laconios adoptaron la estrategia de escalonar las tareas de los hombres, de modo que mientras un grupo dormía, el otro luchaba, y viceversa. Cuando los mesenios quedaron exhaustos, Aristómenes decidió sacar a las mujeres y los niños, y los laconios lo permitieron. Así fue como los mesenios llegaron a su fin tras once años de guerra constante. En resumen, los mesenios fueron derrotados por los espartanos. Finalmente, el oráculo y la profecía se convirtieron en parte integral de la conciencia social. La psicología narrativa ha demostrado que las narrativas son parte integral de las perspectivas y cosmovisiones de las personas. Por lo tanto, la profecía en el mundo antiguo desempeñó un papel importante en la designación de una narrativa, una historia que también moldeó el pensamiento futuro y actual.

description: The interaction between spin and nanomechanical degrees of freedom attracts interest from the viewpoint of basic science and device applications. We study the magnon current induced by the torsional oscillation of ferromagnetic nanomechanical cantilever. We find that a finite Dzyaloshinskii-Moriya (DM) interaction emerges by the torsional oscillation, which is described by the spin gauge field, and the DM interaction leads to the detectably-large magnon current with frequency same as that of the torsional oscillation. Our theory paves the way for studying torsional spin-nanomechanical phenomena by using the spin gauge field.

description: We present strategies how to reconstruct (estimate) properties of a quantum channel described by the map E based on incomplete measurements. In a particular case of a qubit channel a complete reconstruction of the map E can be performed via complete tomography of four output states E[rho_j ] that originate from a set of four linearly independent test states j (j = 1, 2, 3, 4) at the input of the channel. We study the situation when less than four linearly independent states are transmitted via the channel and measured at the output. We present strategies how to reconstruct the channel when just one, two or three states are transmitted via the channel. In particular, we show that if just one state is transmitted via the channel then the best reconstruction can be achieved when this state is a total mixture described by the density operator rho = I/2. To improve the reconstruction procedure one has to send via the channel more states. The best strategy is to complement the total mixture with pure states that are mutually orthogonal in the sense of the Bloch-sphere representation. We show that unitary transformations (channels) can be uniquely reconstructed (determined) based on the information of how three properly chosen input states are transformed under the action of the channel.

description: The main aim of full chemical-kinetics investigation in this work, was recognition of a different role of triphenylphosphine (TPP) in the reaction with dialkyl acetylenedicarboxylates [di-tert-butyl acetylenedicarboxylate (DTBAD), diethyl acetylenedicarboxylate (DEAD) or dimethyl acetylenedicarboxylate (DMAD)] in the presence of SH-acid such as 2-mercaptoquinoline-3-carbaldehyde for the generation of 2H-thiopyrano [2, 3-b] quinoline-2, 3-dicarboxylates. The unexpected and different kinetic results (in comparison with previous work in the presence of TPP) is confirmed by the UV/vis spectrophotometry technique which is accompanied by these results. (1) The reaction followed third-order kinetics. (2) Step1, containing TPP and DTBAD (DEAD or DMAD), was a fast step (kobs = 84.61 M−1.min−1). (3) The rate of overall reaction (TPP, S-H acid and DTBAD) in the presence of dichloromethane solvent (DCM) at 13 °C is (5.87 M−1.min−1), approximately 14.4 times lesser than the fast step. (4) The proposed mechanism is consist of six steps, amongst them, intermediate I3 in step4 having a well sensitive part to any changes in the reaction environment because it is near the reaction center. Any changes in dialkyl acetylenedicarboxylates’ structures can be influenced their inductive and steric effects, corresponding to remarkable changes in the rate of this step4 (k4). (4) For this reason, step4 was recognized as a rate determining-step.

description: The contemporary development of rural areas requires verified agricultural production and support for manufacturing of traditional and regional high-quality products. The aim of the research described in this article has been to assess customer awareness of these products and to identify the features attributed to them in view of existing legal regulations. A catalogue of currently binding regulations has been established, taking account of their axiological assumptions, and results of a survey have been analysed. An assessment of the law functioning in this area has allowed the conclusion that a simplification of the existing regulations and procedures is needed. This is the precondition for the axiological assumptions of the said regulations to be fulfilled. The weight of the discussed subject has been proven by the results of the conducted survey: 93% of the respondents declared buying the described products. The quality of the products, as well as the respondents’ pride in the indigenous culinary tradition, were the main reason for their choice (54%). Examining the laws in the discussed area requires adoption of an interdisciplinary axiological perspective.

description: The objective of the article is to discuss employment in the context of the agriculture intensity in European Union countries based on selected features. The analysis was conducted for 2016. Research was examined using the cluster analysis. The following diagnostic features were used for the analysis: share of working population in agriculture with low educational attainment in total working population (%), share of working population in agriculture in total working population (%), labour productivity in agriculture (EUR/AWU), distribution of GVA by primary sector (%), share of UAA managed by farms with high input intensity per ha (%), average economic farm size (SO/holding in EUR). As a result of the cluster analysis, the examined regions were divided into four groups. According to the results, in countries with high levels of employment in agriculture, the share of added value provided by the agricultural sector is usually smaller. However, in countries with a lower share of people employed in agriculture, the intensity of agriculture is usually higher. / Synopsis. Celem artykułu jest omówienie zatrudnienia w kontekście intensywności w rolnictwie państw Unii Europejskiej na podstawie wybranych cech. Analizę przeprowadzono dla 2016 roku. Badanie przeprowadzono za pomocą analizy skupień. Do analizy przyjęto następujące cechy diagnostyczne: udział ludności czynnej zawodowo w rolnictwie z niskim poziomem wykształcenia w całkowitej liczbie ludności czynnej zawodowo (%), udział ludności zatrudnionej w rolnictwie w ludności zatrudnionej ogółem (%), produktywność pracy w rolnictwie (EUR/AWU), udział wartości dodanej dostarczanej przez sektor rolniczy (%), udział użytków rolnych zarządzanych przez gospodarstwa o dużej intensywności w użytkach rolnych ogółem (%) oraz średnia ekonomiczna wielkość gospodarstw (SO/gospodarstwo w EUR). W wyniku zastosowania analizy skupień podzielono badane państwa na cztery grupy. Zgodnie z wynikami w państwach o wysokim poziomie zatrudnienia w rolnictwie zwykle mniejszy jest udział wartości dodanej dostarczanej przez sektor rolniczy. Natomiast w państwach o niższym udziale zatrudnionych w rolnictwie intensywność rolnictwa jest z reguły większa.

We establish degeneracy in the even and odd particle sectors and extract the masses of the lowest two states and the vacuum energy density for $λ=0.5$ and 1.0. We present two novel results: the Fourier transform of the form factor of the lowest excitation as well as the number density of elementary constituents of that state. A coherent state with kink - antikink structure is revealed.

description: Environmentally friendly methods for the synthesis of T8 H were developed. A combination of triethoxysilane (TES), concentrated HCl aqueous solution, and FeCl3 produced T8 H with almost the same yield as the previously known methods. We also found that HNO3 could be used instead of HCl, resulting in a similar yield. No toxic gases were generated during the reaction with HNO3. Additionally, the synthesis of T8 H based on TES did not generate dangerous substances such as hydrogen chloride and methanol, unlike when trichlorosilane or trimethoxysilane are used. Therefore, our new method for the synthesis of T8 H is considered to be safer, although the yield is the same as the conventional methods.
Classical projected phase space density of billiards and its relation to the quantum Neumann spectrum

description: A comparison of classical and quantum evolution usually involves a quasi-probability distribution as a quantum analogue of the classical phase space distribution. In an alternate approach that we adopt here, the classical density is projected on to the configuration space. We show that for billiards, the eigenfunctions of the coarse-grained projected classical evolution operator are identical to a first approximation to the quantum Neumann eigenfunctions. However, even though there exists a correspondence between the respective eigenvalues, their time evolutions differ. This is demonstrated numerically for the stadium and lemon shaped billiards.

description: At present, the safety and stability of most facility greenhouse environment monitoring systems are seldom considered. In order to improve the stability of data transmission in environment and prevent the system failure caused by the fault of coordinator, a mechanism based on Zigbee coordinator to improve the stability of the whole system is proposed to ensure the security of wireless data transmission. Finally, the system is tested, and the results show that the system can effectively ensure the fault-free transmission of collected environmental data.

description: We investigate how the properties of spiral arms relate to other fundamental galaxy properties. To this end, we use previously published measurements of those properties, and our own measurements of arm-interarm luminosity contrasts for a large sample of galaxies, using 3.6$μ$m images from the Spitzer Survey of Stellar Structure in Galaxies. Flocculent galaxies are clearly distinguished from other spiral arm classes, especially by their lower stellar mass and surface density. Multi-armed and grand-design galaxies are similar in most of their fundamental parameters, excluding some bar properties and the bulge-to-total luminosity ratio. Based on these results, we discuss dense, classical bulges as a necessary condition for standing spiral wave modes in grand-design galaxies. We further find a strong correlation between bulge-to-total ratio and bar contrast, and a weaker correlation between arm and bar contrasts.

description: The effects of atomic-scale disorder and charge (de)localization holds significant importance,and they provide essential insights in unravelling the role that strong and weak correlations play in condensed matter systems.For perovskite oxide heterostructures,while disorders introduced via various external stimuli have strong influences on the (de)localization of the interfacial two-dimensional (2D) electrons, these factors alone could not fully account for the system's charge dynamics where interfacial hybridization holds very strong influence.Here, we determine that the displaced 2D free electrons are localized in the specific hybridized states at the LaAlO3/SrTiO3(LAO/STO) interface.This experimental study combines both transport measurements and temperature-dependent X-ray absorption spectroscopy and suggests the localization of 2D electrons can be induced via temperature reduction or ionic liquid gating and it applies to both amorphous and crystalline interfacial systems.Specifically, we demonstrate that interfacial hybridization plays a pivotal role in regulating the 2D electron localization effects.Our study resolves the location where the 2D electrons are localized and highlights the importance of interfacial hybridization and opens further scientific investigation of its influence on 2D charge localization in oxide heterointerfaces.

description: Navigation applications relying on the Global Navigation Satellite System (GNSS) are limited in indoor environments and GNSS-denied outdoor terrains such as dense urban or forests. In this paper, we present a novel accurate, robust and low-cost GNSS-independent navigation system, which is composed of a monocular camera and Ultra-wideband (UWB) transceivers. Visual techniques have gained excellent results when computing the incremental motion of the sensor, and UWB methods have proved to provide promising localization accuracy due to the high time resolution of the UWB ranging signals. However, the monocular visual techniques with scale ambiguity are not suitable for applications requiring metric results, and UWB methods assume that the positions of the UWB transceiver anchor are pre-calibrated and known, thus precluding their application in unknown and challenging environments. To this end, we advocate leveraging the monocular camera and UWB to create a map of visual features and UWB anchors. We propose a visual-UWB Simultaneous Localization and Mapping (SLAM) algorithm which tightly combines visual and UWB measurements to form a joint non-linear optimization problem on Lie-Manifold. The 6 Degrees of Freedom (DoF) state of the vehicles and the map are estimated by minimizing the UWB ranging errors and landmark reprojection errors. Our navigation system starts with an exploratory task which performs the real-time visual-UWB SLAM to obtain the global map, then the navigation task by reusing this global map. The tasks can be performed by different vehicles in terms of equipped sensors and payload capability in a heterogeneous team. We validate our system on the public datasets, achieving typical centimeter accuracy and 0.1% scale error.

description: Reactions of 3-tert-butyl-8-methylpyrazolo[5,1-c][1,2,4]triazine with lithium phenyldimethylsilanide and triphenylsilanide in THF media at −85 to −60 °C led to the formation of the silicon C(4)-addition products in high yields. Aromatic 3-tert-butyl-8-methyl-4-(triphenylsilyl)pyrazolo[5,1-c][1,2,4]triazine has been synthesized by oxidation of the corresponding 1,4-dihydro derivative using NBS/Et3N in pentane at −30 to −15 °C. Preferential N(1)-nucleophilic additions of silanides were observed for the sterically hindered 3,4-di-R-8-methylpyrazolo[5,1-c][1,2,4]triazines (R = t-Bu, Ph3Si). Novel C–Si derivatives of 1,2,4-triazines, as well as some other isolated compounds were characterized by IR, 1H, 13C, 29Si NMR, HRMS data and X-ray crystallography.

description: Strongly-interacting nanomagnetic arrays are crucial across an ever-growing suite of technologies. Spanning neuromorphic computing, control over superconducting vortices and reconfigurable magnonics, the utility and appeal of these arrays lies in their vast range of distinct, stable magnetisation states. Different states exhibit different functional behaviours, making precise, reconfigurable state control an essential cornerstone of such systems. However, few existing methodologies may reverse an arbitrary array element, and even fewer may do so under electrical control, vital for device integration. We demonstrate selective, reconfigurable magnetic reversal of ferromagnetic nanoislands via current-driven motion of a transverse domain wall in an adjacent nanowire. The reversal technique operates under all-electrical control with no reliance on external magnetic fields, rendering it highly suitable for device integration across a host of magnonic, spintronic and neuromorphic logic architectures. Here, the reversal technique is leveraged to realise two fully solid-state reconfigurable magnonic crystals, offering magnonic gating, filtering, transistor-like switching and peak-shifting without reliance on global magnetic fields.

description: We present the first numerical implementation of a non-perturbative renormalization method for lattice operators, based on the study of correlation functions in coordinate space at short Euclidean distance. The method is applied to compute the renormalization constants of bilinear quark operators for the non-perturbative O(a)-improved Wilson action in the quenched approximation. The matching with perturbative schemes, such as MS-bar, is computed at the next-to-leading order in continuum perturbation theory. A feasibility study of this technique with Neuberger fermions is also presented.

description: In order to formulate feasible conservation measures and develop and utilize Muchuan black-bone chicken rationally, two generations of Muchuan black-bone chicken were bred, and their production performance and slaughter traits (at the age of 300 d) were compared. The results showed that the reproductive performance, slaughter performance and body size of the Muchuan black-bone chicken of Generation 1 (G1) were all improved compared with those of the Generation 0 (G0) (P<0.05). At the age of 300 d, the live weight, carcass weight, and leg muscle weight of the G1 were significantly higher than those of the G0 (P<0.05); and the chest width of the cocks of the G1 was significantly higher than that of the G0 (P<0.05). It suggests that after rigorous selection and utilization of modern poultry breeding techniques, the reproductive performance, slaughter performance and survival rate of Muchuan black-bone chicken can be improved significantly.

description: A bridge going from Wronskian solutions to generalized Wronskian solutions of the Korteweg-de Vries equation is built. It is then shown that generalized Wronskian solutions can be viewed as Wronskian solutions. The idea is used to generate positons, negatons and their interaction solutions to the Korteweg-de Vries equation. Moreover, general positons and negatons are constructed through the Wronskian formulation. A few new exact solutions to the KdV equation are explicitly presented as examples of Wronskian solutions.

description: Azulene, the smallest neutral nonalternant aromatic hydrocarbon, serves as not only a prototype for fundamental studies but also a versatile building block for functional materials because of its unique opto(electronic) properties. Here, we report the on-surface synthesis and characterization of the homopolymer of azulene connected exclusively at the 2,6-positions using 2,6-diiodoazulene as the monomer precursor. As an intermediate to the formation of polyazulene, a gold-(2,6-azulenylene) chain is observed.

description: During the Agrarian Revolutionary War, in order to understand the situation in the countryside, win the revolution and answer the question of the nature of rural society in China, the Chinese Communists spontaneously conducted rural social surveys under the efforts of a group of communists such as Chen Hansheng, Mao Zedong, Zhang Wentian and the China Rural Economic Research Association, forming a more systematic and comprehensive rural summary and laying a solid foundation for the formulation of rural policies. The current rural China is undergoing tremendous changes, and the formulation of rural revitalization strategies and the mobilization of farmers' enthusiasm are inseparable from survey and practice. The rural survey activities of the Communist Party of China during the Agrarian Revolutionary War provide far-reaching practical enlightenment for the work of the Party and the revitalization of the countryside.

description: Hybrid 2-(2-(7-(diethylamino)-2-oxo-2H-chromen-3-yl)vinyl)-1,3-dimethyl-1H-benzo[d]imidazol-3-ium iodide compounds (LHZD-1 ∼ 3) were synthesized by Knoevenagel condensation reaction. Their structures were confirmed by 1H NMR, 13C NMR and HRMS spectroscopy. The fluorescence property of LHZD-1 ∼ 3 varied with the substituent groups such as -Br, -H and -OMe in the benzimidazolium skeleton. The probe LHZD-1 showed remarkable selectivity for the bisulfite ion over other common anions and biotins, which outputted the obvious color change in both absorption (462 nm to 400 nm) and emission (580 nm to 480 nm) spectra. The probe LHZD-1 showed the lysosome positioning action in Hela cells. This study not only provides a way for optimizing coumarin-benzimidazolium probes but also holds considerable promise in detection of bisulfite ion in organelles.

description: The interplay of orbital and spin degrees of freedom is the fundamental characteristic in numerous condensed matter phenomena, including high temperature superconductivity, quantum spin liquids, and topological semimetals. In iron-based superconductors (FeSCs), this causes superconductivity to emerge in the vicinity of two other instabilities: nematic and magnetic. Unveiling the mutual relationship among nematic order, spin fluctuations, and superconductivity has been a major challenge for research in FeSCs, but it is still controversial. Here, by carrying out 77Se nuclear magnetic resonance (NMR) measurements on FeSe single crystals, doped by cobalt and sulfur that serve as control parameters, we demonstrate that the superconducting transition temperature Tc increases in proportion to the strength of spin fluctuations, while it is independent of the nematic transition temperature Tnem. Our observation therefore directly implies that superconductivity in FeSe is essentially driven by spin fluctuations in the intermediate coupling regime, while nematic fluctuations have a marginal impact on Tc.
