Differences in visually induced MEG oscillations reflect differences in deep cortical layer activity
Authors: Pinotsis Dimitris A. , Miller Earl K.
Published: November 2020

Neural activity is organized at multiple scales, ranging from the cellular to the whole brain level. Connecting neural dynamics at different scales is important for understanding brain pathology. Neurological diseases and disorders arise from interactions between factors that are expressed in multiple scales. Here, we suggest a new way to link microscopic and macroscopic dynamics through combinations of computational models. This exploits results from statistical decision theory and Bayesian inference. To validate our approach, we used two independent MEG datasets. In both, we found that variability in visually induced oscillations recorded from different people in simple visual perception tasks resulted from differences in the level of inhibition specific to deep cortical layers. This suggests differences in feedback to sensory areas and each subject’s hypotheses about sensations due to differences in their prior experience. Our approach provides a new link between non-invasive brain imaging data, laminar dynamics and top-down control.
Magmatic volatiles episodically flush oceanic hydrothermal systems as recorded by zoned epidote
Authors: Fox Stephen , Katzir Yaron , Bach Wolfgang , Schlicht Lucy , Glessner Justin
Published: November 2020

Circulation of seawater at oceanic spreading centers extracts heat, drives rock alteration, and transports leached metals to shallower levels of the crust, where they may precipitate and form ore deposits. Crystallization of the lower crust, may exsolve and introduce magmatic volatiles into the seawater-dominant system. However, the role of magmatic volatiles added to the hydrothermal system, including pathways of these fluids are lesser known. Here we present coupled in-situ strontium isotope and rare earth element data of distinct domains in epidote, a common hydrothermal mineral throughout the Troodos ophiolite, to track magmatic fluid input and flow. Epidote crystal domains characterize three distinct strontium isotope-rare earth element signatures—suggesting sequential growth from magma-derived fluids (0.704, negative europium anomalies), rock-buffered fluids (0.7055, positive europium anomalies) and seawater-derived fluids (0.7065, negative cerium anomalies). Epidote records episodic fluxing of magmatic fluids from plagiogranites, through epidosites in the upflow zone and into metal ore deposits.

Purpose

In their letter,
Meister et al. (2020)
appropriately point to a potential influence of stimulus type, arguing cochlear implant (CI) users may have the ability to use timbre cues only for complex stimuli such as sentences but not for brief stimuli such as vowel–consonant–vowel or single words. While we cannot exclude this possibility on the basis of
Skuk et al. (2020)
alone, we hold that there is a strong need to consider type of social signal (e.g., gender, age, emotion, speaker identity) to assess the profile of preserved and impaired aspects of voice processing in CI users. We discuss directions for further research to systematically consider interactive effects of stimulus type and social signal. In our view, this is crucial to understand and enhance nonverbal vocal perception skills that are relevant to successful communication with a CI.
Towards privacy palmprint recognition via federated hash learning
Authors: Shao Huikai , Zhong Dexing
Published: November 2020

Nowadays, deep learning‐based palmprint recognition methods have achieved great success. However, they are mainly focused on the accuracy and ignore the privacy, which is more important in the practical applications. In this Letter, a novel method, federated hash learning (FHL), is proposed for privacy palmprint recognition. There are several agents deploy in different communities, and they have different models and private data. An available public dataset is introduced to provide communications for each agent. Through appropriate federated loss, the agents are connected to help each other train the models to improve the accuracy. Experiments are conducted on constrained and unconstrained palmprint benchmarks. The results demonstrate that the authors’ FHL can outperform other baselines and obtain promising accuracy.
Deterministic hierarchical remote state preparation of a two‐qubit entangled state using Brown et al. state in a noisy environment
Authors: Barik Subhashish , Warke Aakash , Behera Bikash K. , Panigrahi Prasanta K.
Published: November 2020

Quantum communication is one of the cutting‐edge research areas today, where the scheme of remote state preparation (RSP) has drawn significant attention of researchers. The authors propose here a hierarchical RSP protocol for sending a two‐qubit entangled state using a seven‐qubit highly entangled state derived from Brown et al. state. They have also studied here the effects of two well‐known noise models namely amplitude damping (AD) and phase damping (PD). An investigation on the variation of the fidelity of the state with respect to the noise operator and receiver is made. PD noise is found to affect the fidelity more than the AD noise. Furthermore, the higher power receiver obtains the state with higher fidelity than the lower power receiver under the effect of noise. To the best of their knowledge, they believe that they have achieved the highest fidelity for the higher power receiver, 0.89 in the presence of maximum AD noise and 0.72 in the presence of maximum PD noise, compared to all the previously proposed RSP protocols in noisy environments. The study of noise is described in a very pedagogical manner for a better understanding of the application of noise models to a communication protocol.

Context. FU Orionis is the archetypal FUor star, a subclass of young stellar objects (YSOs) that undergo rapid brightening events, often gaining between four and six magnitudes on timescales of days. This brightening is often associated with a massive increase in accretion, which is one of the most ubiquitous processes in astrophysics for bodies ranging from planets and stars to super-massive black holes. We present multi-band interferometric observations of the FU Ori circumstellar environment, including the first J-band interferometric observations of a YSO.

Aims. We investigate the morphology and temperature gradient of the innermost regions of the accretion disk around FU Orionis. We aim to characterise the heating mechanisms of the disk and comment on potential outburst-triggering processes.

Methods. Recent upgrades to the MIRC-X instrument at the CHARA array have allowed for the first dual-band J and H observations of YSOs. Using baselines up to 331 m, we present high-angular-resolution data of a YSO covering the near-infrared bands J, H, and K. The unprecedented spectral range of the data allowed us to apply temperature gradient models to the innermost regions of FU Ori.

Results. We spatially resolved the innermost astronomical unit of the disk and determine the exponent of the temperature gradient of the inner disk to T ∝ r−0.74 ± 0.02. This agrees with theoretical works that predict T ∝ r−0.75 for actively accreting, steady-state disks, which is a value only obtainable through viscous heating within the disk. We found a disk that extends down to the stellar surface at 0.015 ± 0.007 au, where the temperature is found to be 5800 ± 700 K. We found a disk inclined at 32 ± 4° with a minor-axis position angle of 34 ± 11°.

Conclusions. We demonstrate that J-band interferometric observations of YSOs are feasible with the MIRC-X instrument at CHARA. The temperature gradient power-law derived for the inner disk is consistent with theoretical predictions for steady-state, optically thick, viciously heated accretion disks.
Methodology for assessing the grain mass thermal effusivity in a metal silo under the influence of active ventilation
Authors: Kechkin I. A. , Ermolaev V. A. , Romanenko A. I. , Tarakanova V. V. , Sosnina O. B.
Published: November 2020

The purpose of studying the thermal effusivity of the grain mass in a metal silo is to obtain a dynamic mathematical model of the processes of layered changes in the temperature of the grain mass under the influence of an external factor. Such an external factor is the supply of cooling air through the air distribution grid of the bottom of the silo with the active ventilation of grain in a metal silo. The created mathematical and parametric models allow simulating the moisture transfer process using active air ventilation systems inside metal silos during storage of wheat grain. There have been developed some ways to improve the conditions for ensuring the quality preservation of grain during its long-term storage in a metal silo. It is necessary to load such a silo with grain completely, preferably up to the top, leaving free supergrannial space as small as possible. Another solution is thermal insulation of the surfaces of the silo. The task of ensuring the safety of wheat food grain can be accomplished not only on the basis of existing regulatory rules, but also by taking into account the results of new research. The main method of storage in metal containers, according to the instructions and safety regulations is the storage of grain in a dry and purified state. It is known that not only humidity and purity, but also the temperature of the grain put into storage affect the storage period.

Authors: Isaychev Vitaly , Andreev Nikolay , Kostin Vladimir
Published: November 2020

The method of presowing and foliar treatment of spring wheat crops with various growthregulating preparations should be referred to a number of promising techniques that provide increased productivity and quality of crop production. The conducted studies have shown that the highest values of germination energy and laboratory germination during presowing treatment of seeds with experimental preparations were found in the option Megamix-zinc. The use of various modifications of the Megamix preparation for presowing seed inoculation contributes to an increase in the field germination of the experimental crop according to all options, depending on the year of the study. On average, over the years of the research, the used modifications of the Megamix preparation and their combination with mineral fertilizers contribute to an increase in productivity by 0.51–3.23 kg/ha, the best result over control is ensured by the use of the Megamix-zinc modification compared to complex sulfur-containing mineral fertilizers, which is 11.83 %. Thus, the use of experimental preparations and their combinations with complex mineral fertilizers has a positive effect on production processes which ultimately contributes to an increase in the productivity of spring wheat.

Published: November 2020

The paper summarizes the 5-year experimental data of the authors on the study of various technologies for sunflower cultivation in the soil and climatic conditions of the Republic of Tatarstan. Particular attention is paid to improving the methods of rational use of modern technological means with regards to the biological characteristics of the studied culture. It has been established that the classical technology of sunflower cultivation with deepening of the arable layer, diagonal closing of moisture, presowing cultivation to the depth of 6-8 cm, placement of rows in the South-North direction pre- and post- sowing harrowing and inter-row cultivation provides 93 % of the planned yield. The profitability of oilseed production is 69.2 %, and net profit is 13.7 thousand rubles per hectare. 7.4 thousand rubles of proceedings in cash comes to an enterprise from the sale of 1 ton of grown products. In large holding agricultural entities of Tatarstan with sunflower areas of more than 250-300 hectares, weed control using the Clearfield system excludes harrowing of crops and inter-row cultivation. The use of selective herbicide intended only for a single hybrid allows the 70 to 100 % weeds destruction without damaging the main crop. The economic indicators of the mixture of the developed agricultural technology with chemical crops weeding are quite high. Specifically, the profitability is 59.6 % and the cost of production of 1 ton of oilseeds is lower than its sales price by 6.7 thousand rubles.

Authors: Dorozhkin Vasily , Pavlenko Galina , Pavlova Natalia , Drozdov Dmitry
Published: November 2020

According to the constant deterioration of the environmental situation, the issue of preserving health of agricultural animals and obtaining safe livestock products is acute. One of the most effective ways to reduce the accumulation and ecotoxicants impact is pharmacological drugs usage and feed additives with different mechanisms of action. A comparative assessment of various agents exposed to heavy metals and nitrates in laboratory animals is presented. It was found that using feed with an increased content of heavy metals and nitrates increased the level of ecotoxicants in the organs and tissues of animals. Solvimin selenium enabled to reduce the accumulation of cadmium and lead in organism (up to 45 %), restore the normal amount of hemoglobin and the summation threshold, animals’ weight, protein and carbohydrate metabolism. However, it did not restore the indicators of the liver and kidneys functional state. The use of laricarvit showed a fairly high protective efficiency in removing cadmium (25– 30 %) and reducing the nitrates accumulation in the blood and muscles, normalizing the body weight of animals, the number of white blood cells, lymphocytes and methemoglobin. Detox injections successfully reduced the content of nitric nitrogen in the blood, in the liver and, to some extent, in the kidneys, while complete normalization of blood parameters was not observed.

Published: November 2020

The article presents data on the study of the effectiveness of tetra-p feed additive and toxin adsorbents Minazel plus and Sorbitox introduced into feed, naturally contaminated with mycotoxins. The experiment was conducted on young bulls of 9 months age, which for 3 months got the preparations in diets in the following concentrations: the first group – tetra-p – 5.0 kg/t of feed, Minazel plus – 1.5 kg/t of feed, the second group – tetra-p – 5.0 kg/t of feed, Sorbitox (1.5 kg/t of feed). The results of the experiment determined that the use of tetra-p in combination with preparations with sorption activity had a pronounced therapeutic effect on the body of young bulls. An improvement in the clinical condition of animals was observed from 14-16 days of the experimental period and was manifested by an increase in appetite, normalization of the gastrointestinal tract, as well as by an increase in body weight gain by 11.7 % and 10.3 %. Blood biochemical parameters were characterized by an increase in the level of total protein by 12.4–15.8 % (p ≤ 0.01), albumin by 18.0–21.3 %, urea by a factor of 1.53–1.44 (p ≥ 0.01), cholesterol by 1.4–1.56 times and triglycerides by 1.6 times. The activity of liver enzymes decreased by 18.3–21.4 % (ALT) and by 25.7–27.1 % (AST). It has been proved that the developed scheme improves the effectiveness of treatment of mycotoxicosis in animals by the optimizing effect on metabolism, restoration of impaired homeostasis, activation of reparative processes of the liver tissue and increased deposition, activation and utilization of pollutants, produced by microscopic fungi.

Published: November 2020

The results of two–year (2018–2019) studies on the effect of various seeding rates and nutritional backgrounds on the yield and grain quality of two types of spring wheat – soft wheat and emmer wheat (spelt) – are considered. The agrochemical characteristic of the gray forest soil of the experimental plot is as follows: the humus content in the layer of 0–20 cm was 2.9–3.4 % (Tyurin method), mobile phosphorus amount was 176–241 mg, exchange potassium amount was 77–109 mg/kg of soil (Kirsanov method). The degree of saturation with bases was 85.2–87.7 %, the pH of the salt extract was 5.6–5.8. Agrometeorological conditions of 2018–2019, on the whole, met the requirements for early spring crop seeding, HTC (hydrothermal coefficient) was 0.85–1.2. Two levels of mineral nutrition were studied in the experiment (natural background, without fertilizing, NRK for the planned grain yield of 3 t/ha), four seeding rates against each nutrition background: 4, 5, 6 and 7 million germinating seeds per 1 ha. The seedling completeness in both types of wheat over an average of 2 years depended on the seeding rate, regardless of the background of nutrition. In soft wheat of Ulyanovskaya 105 variety, against a natural background, with an increase in the sowing rate from 4 to 7 million germinating seeds per ha, the seedling completeness decreased and amounted to from 82.5 to 76.3 %, in spelt, it was 84.7–78.6 %. On a fertilized ground it was, respectively, 83.4–78.0 and 84.1–77.6 %. Good preservation of plants in both types of wheat from the number of sown seeds and seedlings was noted when the sowing rate was reduced from 7 to 4 million: without fertilizer 82.6–88.5 % in common wheat and 83.5–90.4 % of spelt. On a fertilized ground it amounted, respectively, to 84.3–90.5 and 86.5–92.3 %. Changes in nutritional background by introducing calculated doses of mineral fertilizers for all options with seeding rates on average for 2018–2019 yielded an increase in soft wheat by 0.94 tons of grain per hectare and by 0.61 tons of spelt. The highest conversion efficiency of fertilizers at a sowing rate of 6 million in common wheat was 8.1 kg of grain per 1 kg of a.a., for spelt at a sowing rate of 4 million the figure was 5.6 kg per 1 kg of a.a.
Structural pathology of the endocrine organs of calves with cryptosporidiosis
Authors: Zalyalov Ildar , Mullakaev Orazali , Kirillov Evgeny , Zaikina Elena
Published: November 2020

It is generally accepted in practical veterinary medicine that cryptosporidiosis invasion of the gastrointestinal tract of calves is a local pathological process and the disease outcome is completely determined by the local etiological factor. Pathomorphological changes in the gastrointestinal tract, detected during the invasion, and metabolic disorders in the body of sick calves cannot occur without changes in the structure of adaptive mechanisms. Therefore, studies of the endocrine organs reaction in acute and chronic forms of the cryptosporidiosis course have been carried out. It has been found that calves during the neonatal period have the acute course of invasion accompanied by severe violations of the most functionally loaded structures of the endocrine organs. This is manifested in the form of increased mechanisms of programmed necrosis, the occurrence of reversible and irreversible degenerative processes, and local hemocirculation disorders. The pathological metamorphosis arising from cryptosporidiosis infection in endocrinocytes led to significant violations of the adaptive systems of the calves’ body and ultimately ended in an unfavorable disease outcome. Pathological changes with a predominance of atrophic, sclerotic, and necrobiotic processes in the chronic course of invasion were manifested in all structures of the studied endocrine organs simultaneously. A prolonged state of structural and functional overstrains of the endocrine organs eventually led to the depletion of adaptive hormone resources. The pluriglandular insufficiency state in the body was crucial in the pathogenesis and outcome of the chronic course of cryptosporidiosis in calves.

The article presents the results of a study of pathomorphological changes in the bursal sac of chickens vaccinated against Newcastle disease. The experiment was carried out in the conditions of Sabinsky IPS LLC in the Sabinsky district of the Republic of Tatarstan during the period of raising chickens of the Lomann LSL cross. For research, 60 chickens of 8 weeks of age were taken, which were divided into 4 groups of 15 chickens in each. The birds of the first group were immunized with a once inactivated emulsified vaccine against Newcastle disease with the addition of squalene in the form of emulsion at a dose of 0.5 cm3. The second group was inactivated by the emulsified vaccine against Newcastle disease containing Montanide ISA-71VG adjuvant. The third group was immunized with a vaccine against Newcastle disease without adjuvant, and the remaining 15 chickens were intact. The vaccine in various embodiments was administered to the chickens in a volume of 0.5 cm3 subcutaneously in the dorsal surface of the middle part of the neck. Slaughter of experimental birds of groups 1, 2, 3, and 4 was carried out on the 7th, 14th, and 21st days after vaccination, 6 animals for each study period. Pieces of the bursal sac were preserved in a 10% solution of neutral formalin. After dehydration and compaction of the taken material, the prepared histological sections with a thickness of 8 μm were stained with hematoxylin and eosin and examined under a microscope. Studies of involutional changes in the microstructure of the bursal sac of chickens showed its dependence not only on hereditary mechanisms, but also on additional antigenic stimulation. It has been established that the vaccine against Newcastle disease has reactogenic and immunogenic qualities. In this connection, the most pronounced involutional processes were noted in the bursal sac in chickens of the 3rd group, and the maximum immunogenic qualities of the vaccine preparation were manifested in the structure of the bursal sac in chickens of the 2nd and especially the 1st group. The lowest level of alterative changes in the bursal sac was observed in birds of the 4th group. Involutional processes in these birds were determined by hereditary factors, while the chickens of the remaining groups noted the incidental nature of the manifestation of involution.

Leukemia is a chronic infectious viral disease of a tumor nature. The disease is widespread in different countries of the world and is relevant for most regions of the Russian Federation. The purpose of the work is to study the epizootic situation of leukemia in cattle in livestock farms of the Central Federal District of the Russian Federation. A complex epizootological method and evidence-based epizootology methods were used in the work. Objects of research are dysfunctional points, sick cattle. The paper presents a comparative analysis of the epizootic situation for the period 2012–2016. In the analyzed period, a total of 470 dysfunctional points for leukemia were identified, which amounted to 29.59 % of the total number of dysfunctional points in the Russian Federation and 62908 animals with leukemia were registered, which amounted to 36.90 % of the total number of diseased animals in Russia. Despite the decrease in the number of cattle infected with leukemia in five subjects, and the absence of animals that died from leukemia in all 18 subjects of the Central Federal District of the Russian Federation during 2012–2016, the epizootic situation of leukemia in the whole region remains quite tense, which is explained by the failure to comply with the basic requirements of the state veterinary service regarding sanitary anti-leukemia measures, according to the “Rules for the Prevention and Control of Leukemia of Large R gatogo cattle “ (1999.).

The paper analyzes the regional statistical characteristics of analytical and morphometric properties of agro-gray soils formed in one-factor conditions of the Privyatskaya band of the Pre-Kama region of the Republic of Tatarstan. The sampling of analytical data was carried out in accordance with the systematic group and non-eroded soil analogues. The upper part of the soil profile of the studied soil has a low humus content, medium acid reaction, the profile distribution of the sum of absorbed bases is almost uniform and is in the range of 22.6 to 26.8 mmol /100 g of soil. Generalization of the accumulated analytical and morphological information is a zero cycle of monitoring of arable soils and can serve as a reference for comparison to identify changes in the properties and morphological structure of arable soils in the region. In conditions of intensive agriculture, statistical parameters make it possible to purposefully manage soil fertility in the studied region.

The expansion of zones with the cattle without anti-brucellosis immunity in healthy areas increases the risk of cattle infection from neighboring infected regions and states. There is an urgent problem of developing the anti-brucellosis immunity in the adult cattle. The initial full-dose vaccination with the vaccine from strain B. abortus 82 is fraught with post-vaccination abortion. The study is aimed at the exploration of the immune response and immunity in cows vaccinated against brucellosis according to different schemes with small doses of vaccines from B. abortus strains 19 and 82. The results of the experiment showed that the small-dose revaccination with a vaccine from strain 82 is the most promising, because without any harm to the formed immunity, the problem associated with the reactogenicity and agglutinogenicity of the vaccine can be solved. In addition, a ten-time reduction in the vaccine dose can reduce vaccine production volumes and decrease financial expenses of the farmers.

This paper describes the results obtained when the characteristics of metabolic process changes in leukemia, including brucellosis-complicated leukemia, were studied. To do it, 50 blood serum samples were taken from cows with specific antibodies against bovine leukemia virus (BLV) under the results of immunological diffusion reactions (IDR), indirect immunofluorescence (IIF) and enzyme-linked immunosorbent assay (ELISA). All samples were serologically tested to detect a number of bacterial infections resulted in a possibility to establish that the BLV carrier state in most animals is combined with a bacterial infection, especially brucellosis (46%), chlamydia (20%), paratuberculosis (12%) and campylobacteriosis (8 %). At the next stage, 3 groups of 10 animals each were formed to study the metabolic process level, i.e. clinical healthy animals with no specific antibodies revealed during diagnostic tests for leukemia and other infections (Group 1); BLV carriers (Group 2); brucellosisand virus carrier animals (Group 3). Analysis of the blood chemistry values obtained for the experimental groups showed an uneven path of changes, especially for the protein and fat metabolism parameters. The difference was in albumin and cholesterol concentrations reduced in BLV infected animals, while their level was significantly increased in animals with leukemia associated with brucellosis, on the contrary.

The growing level of public awareness of environmental sustainability increases understanding of environmentally friendly schemes such as ecolabeling. The community began to be moved to be involved in environmental conservation activities including the implementation of the ecolabel scheme. Likewise with Indonesia. Communities in several areas have been motivated to apply the selfdeclared forest honey ecolabel scheme. This encourages the preservation of nature around the forest area where the ecolabel scheme is implemented. However, there are still problems in implementing the ecolabel scheme, namely the welfare of the community. This requires more work from the Government. One of the things that the Government can more easily encourage to help improve the welfare of forest communities is by facilitating areas that implement an ecolabel scheme to become ecotourism destinations. In the post-Covid-19 virus pandemic like today, ecotourism is urgently needed and it is safer and more comfortable for tourists. This study reviews the model of integrating ecolabel schemes with ecotourism which will create a balance between environmental sustainability and community welfare. The research is based on a literacy study along with comparation with other countries. This is a tangible form of sustainable development.

Published: November 2020

This paper investigates magnetotelluric (MT) data recorded along a profile in the Sabalan geothermal region, NW of Iran. To find the range of relevant models consistent with the data, this study employed the so-called regularized, tear zone, and sharp boundary inversions. This study could effectively derive three alternative classes of models. Although the models show stable common resistive and conductive features there are some inconsistent details. Unaltered surface rocks and porous Basalt exhibit a high resistive overburden underlain by relatively more conductive Paleozoic sediments. A common signature of hydrothermal systems appears, and resistivities increase beneath a highly conductive clay cap in deeper parts. An intriguing feature resolved in the smoothest inversion model is a second deep conductor of 30 Ωm resistivities at a depth of 3 km, extending close to the surface. It can be related to the hot, solidified volcanic intrusions, resemblingthe heat source in a geothermal system. This study applied the two other inversion approaches for further hypothesis tests. Although the tear zone inversion re-establish the deep conductor (with 38 Ωm resistivities at 3 km depth), it is absent in the sharp boundary inversion result. This study concludes that the second deep conductor has a limited structure resolution.
