Published: September 2020

Abstract
Composites of reduced graphene oxide (rGO) and layered LiMnO2 (LiMnO2@rGO) were successfully synthesized and demonstrated via a one-pot hydrothermal route at a temperature of 200 °C for 12 h. The obtained LiMnO2@rGO was characterized by x-ray diffraction, transmission electron microscopy, Fourier transform infrared spectra and Raman spectra. Electrochemical performance tests of LiMnO2@rGO and LiMnO2 cathodes exhibited that after graphene oxide was loaded, the discharge capacity and cycling performance were greatly improved, the maximum discharge capacity reached 185.6 mAh g−1 at the current density of 100 mA g−1 with retention capacity higher than 80% even after 100 cycles between 2 and 4.5 V vs. Li+/Li, which is much better than most previous reports (table S1). The principles of the corresponding phenomenon were fully explained by the low electron conductivity, high structural stability and lithium diffusion coefficient of LiMnO2@rGO, which was also proved by cyclic voltammetry testing, electrochemical impedance spectroscopy and relevant equivalent circuit fitting. This work not only provides significant insights into the relationship between the structure and electrochemical performance of electrodes, but also shows the great potential of LiMnO2@rGO composite electrodes applied as the cathode materials of lithium-ion batteries.

Abstract
Clinical data shows that antitumor treatments are often ineffective if tumor cells have metastasized. To gain an effective antitumor therapeutic effect, in this report, the tumor cell was limited to the primary site and simultaneously ablated by chemotherapy. Considering the extremely complicated process of cancer metastasis, we seek to comprehensively suppress tumor metastases at both micro and macro levels, which closely link to migration and interact with each other. At the micro level, the motility of the tumor cell was decreased via accelerating mitochondria fusion. At the macro level, the unfavorable hypoxia environment was improved. A liposome-based multifunctional nanomedicine was designed by coloading latrunculin B (LAT-B), an inhibitor of actin polymerization, and doxorubicin (DOX) into the hydrophobic bilayers and aqueous cavity, respectively. Meanwhile, an oxygen reservoir named perfluoropentane (PFP) was encapsulated into the liposome core to fulfill synergistic treatment of metastatic tumors. In this paper, we demonstrated that the metastasis of the tumor cell could be effectively inhibited by LAT-B through promoting mitochondria fusion without affecting its function, making it as an encouraging candidate for effective anti-metastasis therapy. Meanwhile, we found that the combination of LAT-B and DOX shows a synergistic effect against tumors because the combined effect of these two drugs cover the entire cell proliferation process. In a word, this report presents a potential improvement in the treatment of metastatic cancer.

Abstract
Thermal management is one of the key challenges in nanoelectronic and optoelectronic devices. The development of a van der Waals heterostructure (vdWH) using the vertical positioning of different two-dimensional (2D) materials has recently appeared as a promising way of attaining desirable electrical, optical, and thermal properties. Here, we explore the lateral and flexural thermal conductivity of stanene/2D-SiC vdWH utilizing the reverse non-equilibrium molecular dynamics simulation and transient pump-probe technique. The effects of length, area, coupling strength and temperature on the thermal transport are studied systematically. The projected lateral thermal conductivity of a stanene/2D-SiC hetero-bilayer is found to be 66.67

The lateral thermal conductivity increases as the length increases, while it tends to decrease with increasing temperature.

Abstract
Coherent interaction of a quantum system with environment usually induces quantum decoherence. However, remarkably, in certain configurations the coherent system–environment coupling can be simultaneously explored to engineer a specific dark state of the environment that eliminates the decoherence. Here we report on experimental demonstration of such protocol for suppression of quantum decoherence by quantum decoherence itself. The protocol is based on indirect control of the environment via quantum measurements on quantum probes interacting with the environment prior to the system that should be protected. No direct manipulation with the environment is required to suppress the decoherence. In our proof-of-principle experiment, we demonstrate protection of a single qubit coupled to another single qubit. We implement the required quantum circuits with linear optics and single photons, which allows us to maintain very high degree of control and flexibility in the experiment. Our results clearly confirm the decoherence suppression achieved by the protocol and pave the way to its application to other physical platforms.

Published: September 2020

Abstract
The ground state solution of hydrogen molecule and ions are numerically obtained as an application of our scheme to solve many-electron multi-center potential Schrödinger equation by using one-dimensional hydrogen wavefunctions as basis functions. The all-electron sparse Hamiltonian matrix for the given system is generated with the standard order finite-difference method, then the electronic trial wavefunction to describe the ground state is constructed based on the molecular orbital treatment, and finally an effective and accurate iteration process is implemented to systematically improve the result. Many problems associated with the evaluation of the matrix elements of the Hamiltonian in more general basis and potential are circumvented. Compared with the standard results, the variationally obtained energy of H2
+ is within 0.1 mhartree accuracy, while that of H2 and H3
+ include the electron correlation effect. The equilibrium bond length is highly consistent with the accurate results and the virial theorem is satisfied to an accuracy of −V/T = 2.0.
Exploration of youth knowledge and perceptions of individual-level climate mitigation action
Authors: Pickering Gary J , Schoen Kaylee , Botta Marta , Fazio Xavier 
Published: September 2020

AbstractThe current climate crisis necessitates effective mitigation action across all scales, including behaviours and lifestyle decisions at the individual level. Youth need to align lifestyle with the 2.1 tonnes of CO2emissions per person per year required by 2050 to prevent the worse impacts of climate change (CC), yet little is known regarding their preparedness to act nor knowledge of the efficacy of the personal actions available to them. The main objectives of this study were to determine in a representative sample of 17–18 year old Canadians (n= 487) their: (1) beliefs around whether their activities or lifestyle choices can help to lessen CC, and (2) knowledge of the efficacy of individual-level behaviours in reducing greenhouse gas emissions (GGE). Results from the online survey (Likert scale) show that youth have limited confidence in how well their schooling has prepared them for CC and mitigation. However, the majority (88%) believe that their activities and lifestyle choices can help in mitigating CC. Knowledge of the relative efficacy of GGE-reducing actions was generally poor (Wilcoxon signed rank tests and open-ended responses) with, for instance, recycling overestimated and having one fewer child underestimated, suggesting that youth are not well equipped with the requisite knowledge to maximise CC mitigation through their personal choices. Our findings inform high school curricula and CC education and policy more broadly.

AbstractBreath analysis holds promise for non-invasivein vivomonitoring of disease related processes. However, physiological parameters may considerably affect profiles of exhaled volatile organic substances (VOCs). Volatile substances can be released via alveoli, bronchial mucosa or from the upper airways. The aim of this study was the systematic investigation of the influence of different sampling sites in the respiratory tract on VOC concentration profiles by means of a novel experimental setup.After ethical approval, breath samples were collected from 25 patients undergoing bronchoscopy for endobronchial ultrasound or bronchoscopic lung volume reduction from different sites in the airways. All patients had total intravenous anaesthesia under pressure-controlled ventilation. If necessary, respiratory parameters were adjusted to keep PETCO2= 35–45 mm Hg. 30 ml gas were withdrawn at six sampling sites by means of gastight glass syringes: S1 = Room air, S2 = Inspiration, S3 = Endotracheal tube, S4 = Trachea, S5 = Right B6 segment, S6 = Left B6 segment (S4–S6 through the bronchoscope channel). 10 ml were used for VOC analysis, 20 ml for PCO2determination. Samples were preconcentrated by solid-phase micro-extraction (SPME) and analysed by gas chromatography–mass spectrometry (GC-MS). PCO2was determined in a conventional blood gas analyser.Statistically significant differences in substance concentrations for acetone, isoprene, 2-methyl-pentane and n-hexane could be observed between different sampling sites. Increasing substance concentrations were determined for acetone (15.3%), 2-methyl-pentane (11.4%) and n-hexane (19.3%) when passing from distal to proximal sampling sites. In contrast, isoprene concentrations decreased by 9.9% from proximal to more distal sampling sites. Blank bronchoscope measurements did not show any contaminations.Increased substance concentrations in the proximal respiratory tract may be explained through substance excretion from bronchial mucosa while decreased concentrations could result from absorption or reaction processes. Spatial mapping of VOC profiles can provide novel insights into substance specific exhalation kinetics and mechanisms.
Modeling of mechanized cutting of fruit trees

Published: September 2020

Abstract
In the complex of agrotechnical measures for garden care, cutting is one of the most effective methods of stimulating plants. With the help of cutting, crowns of young plants are formed, during the period of increasing aging, the crown is rejuvenated to restore growth, increase productivity and quality of fruits. In the practice of gardening, thickened plantings are widely introduced, in which the number of plants per unit area is significantly increased. In growing fruit trees in a row close together. In such plantings, the crowns are formed with one, maximum two branching orders. This makes it possible to cut the crowns of trees from above or from the sides in the same plane, without violating the subordination of branches. Such cutting can be carried out using machines and thus significantly reduce the amount of manual cutting, which will be reduced to removing the conductor and thinning the thickening branches in the central part of the crown. Contour cutting helps increase the productivity of pest and disease tree control units, reducing the consumption of pesticides. Machines for contour cutting the crown must provide a high-quality cut of branches with a diameter of 5 … 75 mm. Studies of national and foreign scientists have found that segmental cutting devices satisfactorily cut branches up to 20 mm in diameter, and disk-type cutting devices cut branches over 20 mm. However, in gardens, branches of different diameters occupy a very different spatial position. To significantly expand the capabilities of machines with different forms of cutting (light, heavy), fruit tree crown cutters are often equipped with interchangeable cutting devices (segment and disk). This complicates the machine, but makes it possible to use the cutting device of the most optimal type when cutting in specific conditions.

Abstract
At the present stage of Russia’s development, the solution of several national problems is of strategic importance: increasing the demographic potential of Russia, developing agricultural production to diversify the economy, and effectively implementing the country’s agricultural potential to strengthen food security. The solution of these problems is impossible without ensuring sustainable development of Russian rural territories. The actuality and practical significance of solving this problem determined the need to set and solve the following research tasks: determining the features and criteria for sustainable development of rural territories based on the concept analysis of “development”, “sustainability”, “rural territories”, and “sustainable development of rural territories”. The study made it possible to clarify the essence of the category “sustainable development of rural territories” and to highlight its features. The results of determining the features of sustainable development of rural territories allowed us to identify the composition of regulatory territories and criteria for sustainable development of rural territories. The study laid the foundation for a special system of indicators for sustainable development of rural territories.

Abstract
In the context of modern regional development strategies, much attention is paid to agriculture. Socio-economic development of most regions is impossible without active renewal by modern methods and approaches of the agricultural industry. The article discusses the integration processes of the agro-industrial complex. The information base of the study was made up of statistical materials of social and economic development of the regions of the Siberian Federal District. Economic methods of agricultural development analysis were used as research tools, as well as the method of calculating Grubel-Lloyd integration indicators. The first part of the article considers agro-industrial processes, which are the basis for improving the efficiency of the regions through the development of the agricultural industry, which is facilitated by integration processes. The second part of the article carries out calculations of integration processes and proposes an econometric approach to measuring the integration of agricultural enterprises on the basis of building ranks on the indicators of density, differentiation and interconnectedness of intraregional processes. Integration criteria of SFO regions were also calculated and justification of “necessity” and “possibility” of implementation of agro-industrial integration was fulfilled. On the basis of the presented material, qualitative reform of programs for the development of agro-industrial complexes is possible due to integration processes.

Published: September 2020

Abstract
At present, poultry farming provides the population with such important food products as meat and eggs. The basis for the success of poultry farming is a rational feed base, since protein and mineral deficiency leads to a decrease in profitability. In the Far East, there are opportunities for using inexpensive waste from processing marine shellfish. This article presents the results of using Japanese Corbicula flour in the feeding of laying hens. Additions of marine origin have antioxidant, radioprotective activity, increase the body’s resistance to diseases, increase the immune system, and improve metabolism. So that, the purpose of our research work was to study the possibility of including these additions in poultry rations. Our research work proved that using of Corbicula Japonica had a positive effect on egg mass, egg production and finally economic indicators.

Abstract
The construction of modern poultry farms has significantly increased the proportion of bird droppings in the total production of organic fertilizers. Due to the high concentration of poultry farms on the territory of the Mari El Republic, the need has arisen to search for and scientifically sound introduction of new technologies that are not traditional for our zone of fertilizers, techniques and methods of growing crops based on agricultural biologization in order to significantly reduce the chemical load on the soil. One of the methods to improve soil fertility is the use of granular organic fertilizers based on bird droppings. We conducted studies on the use of GOF based on chicken droppings in the cultivation of spring wheat. Studies have shown that the use of granular organic fertilizers contributed to a significant increase in spring wheat yields. The highest value was observed for the option with the introduction of GOF at a dose of 400 kg/ha, and amounted to 2.18 t/ha, which is 34.6% higher than the option without fertilizers. It should be noted that the use of GOF based on bird droppings contributed to the reduction of root rot susceptibility of spring wheat, the smallest spread and development of root rot was in the variant with 400 kg/ha - 44.7% and 24.1%, which is 28.8% and 41.4% less than in the variant without fertilizers.

Abstract
Modern national economies are multilevel with many sectors, sub-sectors, sectors interconnected and competing. But the main thing in this kind of a pie is the value chain, which is a kind of industrial-economic-logistic communications, through which national economies interact both within themselves and without. But value chains have different lengths, and therefore bring different results. Until now, the discussion has been going on about what forms value chains, what is their nature, what mechanisms, and most importantly, is it possible to arbitrarily form value chains of any length and configuration? Practice shows that, firstly, even the most advanced national economies are not always able to form value chains of the desired length and configuration, and secondly, even if they somehow turn out to be created, they often scatter without bringing the desired result. Therefore, it is important for theorists to recognize not only the nature and character of economic (including production, logistics, etc.) value chains formation (with an appropriate set of issues related to their structure, internal mechanism, configuration, etc.), but also why they fall apart without creating the synergistic effect intended. The article suggests that there is “The resource predestination” imposed on the formation of value chains of a given configuration, length and marketability. To achieve this goal, the article combines two independent areas of economic research: the formation of value chains and the “resource curse/predestination”.

Abstract
The article is devoted to the study of the current state of dairy cattle breeding and the provision of milk and dairy products to the population of the Republic of Buryatia, a region with a continental climate. Per capita production of milk and dairy products does not provide a level of per capita consumption. Their actual consumption is below rational norms. The resources of milk and dairy products have declined in recent years compared with 1990 almost 40% due to a significant decrease in the number of cows and their productivity. The largest share of cattle, including cows are concentrated in households when they are reduced in the public sector. Therefore, the volume of production of these products in agricultural organizations decreased by 18 times compared with the pre-reform period.
