In the present study, the aim was to determine alteration of NEFA, calcium and vitamin D3 levels in cow and calf pairs at parturition as well as correlation between each parameter levels. For this purpose, a cow-side device employing the enzymatic colorimetric method was used for measurement of NEFA and calcium levels. On the other hand, serum 25(OH)D3 analysis was performed using the fluorescence immunochromatographic method at the laboratory in the Faculty. Blood samples were taken from Vena jugularis of 15 Simmental cow and calf pairs immediately after parturition and placed in serum and heparinized tubes. In cow and calf pairs, concentration of vitamin D3 (15.6-120 and 31.8-120 ng/mL, respectively), NEFA (0.12-1.2 and 0.09-0.8 mmol/L, respectively) and calcium (1.8 ± 0.9 and 2.2 ± 0.6 mmol/L, respectively) were determined. There was no significant correlation between NEFA, Ca, and vitamin D3 in cows and calf pairs. Taking into account several co-factors that influenced test results, which could not easily be excluded, further studies may be warranted with larger cow-calf pair populations. In conclusion, vitamin D3 concentration in calves is not affected by the negative energy balance of dams in the parturition period.

INFerence-as-a-Service (INFaaS) has become a primary workload in the cloud. However, existing FPGA-based Deep Neural Network (DNN) accelerators are mainly optimized for the fastest speed of a single task, while the multi-tenancy of INFaaS has not been explored yet. As the demand for INFaaS keeps growing, simply increasing the number of FPGA-based DNN accelerators is not cost-effective, while merely sharing these single-task optimized DNN accelerators in a time-division multiplexing way could lead to poor isolation and high-performance loss for INFaaS. On the other hand, current cloud-based DNN accelerators have excessive compilation overhead, especially when scaling out to multi-FPGA systems for multi-tenant sharing, leading to unacceptable compilation costs for both offline deployment and online reconfiguration. Therefore, it is far from providing efficient and flexible FPGA virtualization for public and private cloud scenarios. Aiming to solve these problems, we propose a unified virtualization framework for general-purpose deep neural networks in the cloud, enabling multi-tenant sharing for both the Convolution Neural Network (CNN), and the Recurrent Neural Network (RNN) accelerators on a single FPGA. The isolation is enabled by introducing a two-level instruction dispatch module and a multi-core based hardware resources pool. Such designs provide isolated and runtime-programmable hardware resources, which further leads to performance isolation for multi-tenant sharing. On the other hand, to overcome the heavy re-compilation overheads, a tiling-based instruction frame package design and a two-stage static-dynamic compilation, are proposed. Only the lightweight runtime information is re-compiled with ∼1 ms overhead, thus guaranteeing the private cloud’s performance. Finally, the extensive experimental results show that the proposed virtualized solutions achieve up to 3.12× and 6.18× higher throughput in the private cloud compared with the static CNN and RNN baseline designs, respectively.

The objective of this work was to collect information on the curative use of plants in the municipality of Teziutlán, Puebla through semi-structured interviews. Thus, 78 plants used for medicinal purposes were identified, of which 40 are native to Mexico and 38 introduced; The value of use (UV) of each one and the Informant's Consensus Factor (FCI) of 10 categories of diseases were calculated. The five most frequently used plants are Ruta chalepensisL., Rosmarinus officinalis, Arnica montana, Loeselia mexicana(Lam.) Brandegee and Sambucus ceruleavar., Neomexicana, which underwent a chemical and pharmacological review. On the other hand, the most frequent preparations are infusion and decoction, using mainly leaves (49.34%) and flowers (19.51%). It is concluded that the inhabitants of Teziutlán have a fairly homogeneous ethnomedical knowledge, setting the standard for research on its pharmacological properties.

This article analyzes the influence of the ancient classical literary language - the Wenyan communication language on the Baihua language. Lexical and grammatical differences are discussed on both fronts of a language. Since the Wenyan language is represented by monosyllabic units, several meanings of a hieroglyph have the property of changing its semantic meaning according to the position of the hieroglyph in the sentence or sentence. It is extremely important to pay attention to this aspect in reading and interpreting ancient texts. The Baihua language, on the other hand, is represented by polysyllabic units, which are much more convenient than the Wenyan language in expressing the semantic meaning of a word. However, the Wenyan language played an important role in the formation of the Baihua language, and to this day some elements of the Wenyan language are also reflected in the Putonghua.

The article examines the struggle of the Qatari- Turkish alliance for regional leadership in the Federal Republic of Somalia. The analysis revealed that the foreign policy activity of Turkey and Qatar in Somalia began during the events of the Arab Spring. Ankara and Doha used diplomatic, military and fi nancial instruments to strengthen their infl uence in the country. Moreover, Qatari money played an important role in promoting pro-qatari candidates to power during the 2012 and 2017 presidential elections. However, the eff orts of the Turkish- Qatari alliance to strengthen its position in Somalia have clashed with the interests of the Saudi- Emirati bloc seeking regional dominance. On the other hand, the inability to close the main cooperation with the central government in Somalia forced the UAE to support such autonomous regions as Somaliland, thereby intensifying the destabilization processes in the country.

В статье анализируются особенности восприятия лесного пространства башкирами. На основе языковых, фольклорных материалов сделана попытка раскрыть различные аспекты взаимоотношений лес - человек, образ леса в картине мира башкир. Как и в большинстве традиционных культур, в целом мифологический образ леса носит отрицательный характер. В фольклоре он часто описывается как тёмный, мрачный, неизвестный, таящий опасности, противопоставляясь обжитому и освоенному пространству селений. Лесной пандемониум также представлен в основном отрицательными персонажами. В целом образ леса в традиционной картине мира башкир предстаёт довольно неоднозначным. С одной стороны - это категория, связанная с потусторонним миром, неизведанная, «чужая» территория. С другой - лес издавна являлся источником различных благ - в виде строительного материала, пушнины, различных продуктов питания, укрывал от врагов. The article analyzes the features of Bashkirs' perception of the forest space. On the basis of the materials of the epos, folklore, folk ideas, an attempt was made to reveal the various aspects of the relationship between forest and man, the image of the forest in Bashkirs' world view. As in most traditional cultures, the mythological image of the forest as a whole is negative. In folklore, it is often described as dark, gloomy, unknown, fraught with danger, being contrasted with the inhabited and developed space of the villages. The forest pandemonium is also represented mainly by negative characters. On the other hand, in the domestic perception forest is valued for the benefits derived from it: shelter, food, protection from enemies. In addition, Bashkirs, distinguished by a developed aesthetic perception and contemplative thinking, appreciated its beauty, which is also reflected in folklore. In general, the image of forest in the Bashkirs' traditional view of the world appears rather ambiguous. On the one hand, it is the category associated with the other world, unknown, «foreign» territory. On the other hand, the forest has long been a source of various benefits - in the form of construction materials, furs, various food products, and it sheltered them from enemies.

This article investigates the meaning of Merleau-Ponty’s concept of the flesh of the world. This concept brings a cosmological tone to existentialist phenomenology and challenges the grim and gnostic approach that prevails in Heidegger’s and Sartre’s works in particular. Is horror the key mood in ontology as argued by Malabou? This article contends that bright metaphors and magic realism are at least as fundamental, but under one condition: ontology must come to terms with what the author has coined as the “Chandos complex”, namely a form of ambivalence and oscillation between Gnosticism and holism that makes both positions fake and hollow. Dreaming of being one with the world and fantasizing an estrangement from nature work hand in hand and are equally staged. Merleau-Ponty’s philosophy occasionally falls prey to the Chandos complex, which makes his concept of the flesh of the world vulnerable to criticism. This article examines the claim put forward by Renaud Barbaras that “the flesh of the world” is a failed metaphor. It argues that this blissful metaphor is ontologically fundamental as soon as its intrinsic paradoxes are recognized and accepted: the Chandos complex then becomes the key to an ontology that recognizes the imaginary as an essential dimension of being. At stake is an essential link between ontology on the one hand and, on the other hand, metaphors as well as myth-building and narrative-building processes.

A Zr-loaded P-containing biomass-derived activated carbon (ACPZr) has been tested for methanol dehydration between 450 and 550 °C. At earlier stages, methanol conversion was complete, and the reaction product was mainly dimethyl ether (DME), although coke, methane, hydrogen and CO were also observed to a lesser extent. The catalyst was slowly deactivated with time-on-stream (TOS), but maintained a high selectivity to DME (>80%), with a higher yield to this product than 20% for more than 24 h at 500 °C. A kinetic model was developed for methanol dehydration reaction, which included the effect of the inhibition of water and the deactivation of the catalyst by coke. The study of stoichiometric rates pointed out that coke could be produced through a formaldehyde intermediate, which might, alternatively, decompose into CO and H2. On the other hand, the presence of 10% water in the feed did not affect the rate of coke formation, but produced a reduction of 50% in the DME yield, suggesting a reversible competitive adsorption of water. A Langmuir–Hinshelwood reaction mechanism was used to develop a kinetic model that considered the deactivation of the catalyst. Activation energy values of 65 and 51 kJ/mol were obtained for DME and methane production in the temperature range from 450 °C to 550 °C. On the other hand, coke formation as a function of time on stream (TOS) was also modelled and used as the input for the deactivation function of the model, which allowed for the successful prediction of the DME, CH4 and CO yields in the whole evaluated TOS interval.

The sensitivity of Photoelectron Circular Dichroism (PECD) in the angular distribution of photoelectrons, a recent chiral technique, to detect chirality in pure hydrocarbons is investigated in a number of benchmark molecules. It is found that a very large chiral signal is expected, surpassing most current examples, giving a sure fingerprint of absolute configuration. On the other hand, the sensitivity to specific isomers or closely related molecules is relatively modest.
