Administrative organization of villages of Spassky rural settlement in the late 19th and early 29th centuries
Authors: Verevkina E. D. , Sitnikova E. V. 
Published: February 2021

The article discusses the formation of Siberian settlements on the example of villages of the Spassky rural settlement (the Tomsk region, Russia). The influence of the MoskovskoSibirskii Tract on the development of villages is determined by the number of houses and residents. The analysis of the villages of the Spassky rural settlement includes the history of the formation of settlements; territorial management units; volost management; volost assignment to settlements after 1861, and changes in the volost boundaries based on lists of settlements in Tomsk Gubernia at the end of the 19th and early 20th centuries. The relevance of the study is determined by little information on the historical and cultural heritage of Tomsk villages and the problems of preserving historical rural settlements in Russia.Purpose: A study the history and development of villages in the Spassky rural settlement. Practical implications: the results obtained can be used in the implementation of design work on the prospective development of old Siberian villages. Scientific novelty: Historical study of the formation and development of settlements in the Spasskoye rural settlement, which has not been studied previously. Methodology/Approach: The critical analysis of the literature, system and structural analysis of information and creative synthesis of conclusions were used in this work. Theoretical works of historians and architects listed in the bibliographic list of this article. Research findings: The formation of villages in Siberia occurred, to a large extent, owing to immigrants from the European part of Russia, who brought their own traditions of housekeeping. The analysis of the volost distribution of the villages of the Spassky rural settlement shows that the territories inhabited by certain nationalities transformed to separate volosts and were called foreign. The growth in the number of courtyards and residents of settlements in the adjacent villages of the Tomsk Province confirmed the more intensive development of the adjacent villages.

OBJECTIVE
Epileptic spasms (ESs) are classified as focal, generalized, or unknown onset ESs. The classification of ESs and surgery in patients without lesions apparent on MRI is challenging. Total corpus callosotomy (TCC) is a surgical option for diagnosis of the lateralization and possible treatment for ESs. This study investigated phase-amplitude coupling (PAC) of fast activity modulated by slow waves on scalp electroencephalography (EEG) to evaluate the strength of the modulation index (MI) before and after disconnection surgery in children with intractable nonlesional ESs. The authors hypothesize that a decreased MI due to surgery correlates with good seizure outcomes.

METHODS
The authors studied 10 children with ESs without lesions on MRI who underwent disconnection surgeries. Scalp EEG was obtained before and after surgery. The authors collected 20 epochs of 3 minutes each during non–rapid eye movement sleep. The MI of the gamma (30–70 Hz) amplitude and delta (0.5–4 Hz) phase was obtained in each electrode. MIs for each electrode were averaged in 4 brain areas (left/right, anterior/posterior quadrants) and evaluated to determine the correlation with seizure outcomes.

RESULTS
The median age at first surgery was 2.3 years (range 10 months–9.1 years). Two patients with focal onset ESs underwent anterior quadrant disconnection (AQD). TCC alone was performed in 5 patients with generalized or unknown onset ESs. Two patients achieved seizure freedom. Three patients had residual generalized onset ESs. Disconnection surgeries in addition to TCC consisted of TCC + posterior quadrant disconnection (PQD) (1 patient); TCC + AQD + PQD (1 patient); and TCC + AQD + hemispherotomy (1 patient). Seven patients became seizure free with a mean follow-up period of 28 months (range 5–54 months). After TCC, MIs in 4 quadrants were significantly lower in the 2 seizure-free patients than in the 6 patients with residual ESs (p < 0.001). After all 15 disconnection surgeries in 10 patients, MIs in the 13 target quadrants for each disconnection surgery that resulted in freedom from seizures were significantly lower than in the 26 target quadrants in patients with residual ESs (p < 0.001).

CONCLUSIONS
In children with nonlesional ESs, PAC for scalp EEG before and after disconnection surgery may be a surrogate marker for control of ESs. The MI may indicate epileptogenic neuronal modulation of the interhemispheric corpus callosum and intrahemispheric subcortical network for ESs. TCC may be a therapeutic option to disconnect the interhemispheric modulation of epileptic networks.

OBJECTIVE
Complications in pediatric neurooncology surgery are seldom and inconsistently reported. This study quantifies surgical morbidity after pediatric brain tumor surgery from the last decade in a single center, using existing morbidity and outcome measures.

METHODS
The authors identified all pediatric patients undergoing surgery for an intracranial tumor in a single tertiary pediatric neurosurgery center between January 2008 and December 2018. Complications between postoperative days 0 and 30 that had been recorded prospectively were graded using appropriate existing morbidity scales, i.e., the Clavien-Dindo (CD), Landriel, and Drake scales. The result of surgery with respect to the predetermined surgical aim was also recorded.

RESULTS
There were 477 cases (364 craniotomies and 113 biopsies) performed on 335 patients (188 males, median age 9 years). The overall 30-day mortality rate was 1.26% (n = 6), and no deaths were a direct result of surgical complication. Morbidity on the CD scale was 0 in 55.14%, 1 in 10.69%, 2 in 18.66%, 3A in 1.47%, 3B in 11.74%, and 4 in 1.05% of cases. Morbidity using the Drake classification was observed in 139 cases (29.14%). Neurological deficit that remained at 30 days was noted in 8.39%; 78% of the returns to the operative theater were for CSF diversion.

CONCLUSIONS
To the authors’ knowledge, this is the largest series presenting outcomes and morbidity from pediatric brain tumor surgery. The mortality rate and morbidity on the Drake classification were comparable to those of published series. An improved tool to quantify morbidity from pediatric neurooncology surgery is necessary.
Diodore of Tarsus. Preface to the Commentary on Psalms (Fragment)
Authors: Заболотный Е. А. 
Published: February 2021

Вниманию читателей предлагается первый перевод на русский язык основного фрагмента из введения, которым Диодор, епископ Тарсийский, предварил своё «Толкование на псалмы». Указанный фрагмент, содержащий рассуждения Диодора о преимуществах историко-грамматической экзегезы над аллегорической, даёт важный материал для изучения методов толкования Священного Писания, развивавшихся в Антиохийской школе. Введение не оставляет сомнений в том, что Диодор, вопреки распространённому мнению, чётко различал аллегорию и анагогическое толкование, или «более возвышенное умозрение», фактически близкое к типологии. Последнюю он несомненно считал допустимой, хотя и подчинённой буквальному знанию текста. В своём «Толковании» Диодор раскрыл expressis verbis основы своего подхода к исследованию Библии, сформировавшего не одно поколение толкователей в рамках «школьной» традиции. Изучение указанного текста позволит составить представление о позднеантичных и средневековых моделях и инструментах познания.
The author offers the first translation into Russian of the theoretical introduction, which Diodore, bishop of Tarsus, placed at the beginning of his Commentary on Psalms. This fragment, including Diodore’s thoughts on the advantages of historical-grammatical exegesis in comparison with allegory, provides an important material for studying biblical interpretation having been used by the School of Antioch. The introduction leaves no doubt that Diodore, contrary to the previously widespread views, clearly discerned between allegory and anagogical interpretation, or «the more elevated insight», which is, in fact, close to typology. Unquestionably, the latter he considered valid, but subordinate to literal meaning of the text. In the introduction, Diodore had revealed expressis verbis the foundations of his scriptural exegesis, which formed some generations of interpreters within the «school» tradition. Studying this text will make it possible to understand late antique and medieval models and tools of cognition.

Protocol security verification is one of the best success stories of formal methods. However, some aspects important to protocol security, such as time and resources, are not covered by many formal models. While timing issues involve e.g., network delays and timeouts, resources such as memory, processing power, or network bandwidth are at the root of Denial of Service (DoS) attacks which have been a serious security concern. It is useful in practice and more challenging for formal protocol verification to determine whether a service is vulnerable not only to powerful intruders, but also to resource-bounded intruders that cannot generate or intercept arbitrarily large volumes of traffic. A refined Dolev–Yao intruder model is proposed, that can only consume at most some specified amount of resources in any given time window. Timed protocol theories that specify service resource usage during protocol execution are also proposed. It is shown that the proposed DoS problem is undecidable in general and is PSPACE-complete for the class of resource-bounded, balanced systems. Additionally, we describe a decidable fragment in the verification of the leakage problem for resource-sensitive timed protocol theories.

Background: No doubt, new communication technology has turned the whole world into a "Global Village". Technology, as it is, though, like two sides of a coin, carries both the negative and the positive sides of it. It allows people to be well educated, enlightened, and keep up with changes in the world. Technology is exposing society to a new way to do stuff. Objective of the study: Effect of digital media on academic performance in undergraduate students.
Materials and Methods: The research population consisted of all students who from 2017-2020 academic years are studying at Malwanchal University willing to participate in the study and complete the questionnaires entirely. Stratified sampling at random was done. Variables of social media use were measured by the Merton (1968) social network site use scale and academic performance was evaluated according to the self-reported GPA.
Results: The results showed that the mean percentage of users belonging to low social network sites among the sample categories, average users of social network sites and high users of social network sites varied significantly. Conclusion: The use of social networking sites on the Internet has a negative effect on academic success. The value of learning to balance the use of social networking sites for better purposes is found to aid in their academic standing.

IntroductionCOVID-19 is raising with a second wave threatening many countries. Therefore, it is important to understand COVID-19 characteristics across different countries.MethodsThis is a cross-sectional descriptive study of 525 hospitalized symptomatic COVID-19 patients, from the central federal hospital in Dubai-UAE during period of March to August 2020.ResultsUAE’s COVID-19 patients were relatively young; mean (SD) of the age 49(15) years, 130 (25%) were older than 60 and 4 (&lt;1%) were younger than 18 years old. Majority were male(47; 78%). The mean (SD) BMI was 29 (6) kg/m2. While the source of contracting COVID-19 was not known in 369 (70%) of patients, 29 (6%) reported travel to overseas-country and 127 (24%) reported contact with another COVID-19 case/s. At least one comorbidity was present in 284 (54%) of patients and 241 (46%) had none. The most common comorbidities were diabetes (177; 34%) and hypertension (166; 32%). The mean (SD) of symptoms duration was 6 (3) days. The most common symptoms at hospitalization were fever (340; 65%), cough (296; 56%), and shortness of breath (SOB) (243; 46%). Most of the laboratory values were within normal range, but (184; 35%) of patients had lymphopenia, 43 (8%) had neutrophilia, and 116 (22%) had prolong international normalized ratio (INR), and 317 (60%) had high D-dimer. Chest x ray findings of consolidation was present in 334 (64%) of patients and CT scan ground glass appearance was present in 354 (68%). Acute cardiac injury occurred in 124 (24%), acute kidney injury in 111 (21%), liver injury in 101 (19%), ARDS in 155 (30%), acidosis in 118 (22%), and septic shock in 93 (18%). Consequently, 150 (29%) required ICU admission with 103 (20%) needed mechanical ventilation.ConclusionsThe study demonstrated the special profile of COVID-19 in UAE. Patients were young with diabetes and/or hypertension and associated with severe infection as shown by various clinical and laboratory data necessitating ICU admission.

Background: Transcatheter closure of paravalvular leak (PVL) has evolved into an alternative to surgery in high-risk patients. In this study, we introduce a new access for transcatheter closure of PVL and seek to evaluate the feasibility and safety of this access.Methods: We retrospectively analyzed patients undergoing transbrachial access for transcatheter mitral or aortic PVL closure (August 2017–November 2019) at our hospital. All patients underwent puncture of the brachial artery under local anesthesia.Results: The study population included 11 patients, with an average age of 55.91 ± 14.82 years. Ten out of 11 patients were successfully implanted with devices via the brachial artery approach, and one patient was converted to the transseptal approach. The technical success rate of transbrachial access was 90.9%. Mean NYHA functional class improved from 3.1 ± 0.5 before the procedure to 1.9 ± 0.5 after PVL closure. Severe paravalvular regurgitation (PVR) in five patients and moderate PVR in six patients prior to the procedure were significantly reduced to mild in four patients and none in seven patients after the procedure. Complications included one case of pseudoaneurysm and one case of moderate hemolysis aggravation after closure. One patient had an unknown cause of sudden death within 24 h after the procedure. The half-year mortality rate during follow-up was 9.1% (1/11).Conclusions: Transbrachial access for transcatheter closure of PVL may be a feasible and safe treatment and should include well-selected patients. It has several potential advantages of simplifying the procedure process and reducing postprocedural bed rest time.
Novel High-Speed Turbo Compressor With Integrated Inverter for Fuel Cell Air Supply

Published: February 2021

Fuel cell technology is continuously gaining ground in E-mobility applications. Fuel cells require a constant supply of pressurized air, for which high-speed turbo compressors with air bearings are an optimal choice to reduce size, guarantee oil-free operation required for the lifetime of the fuel cell, and increase efficiency. However, the inverter driving the electric motor of the turbo compressor does not scale down with increasing speed; therefore, other technology advances are required to achieve an overall compressor system with low weight. New power electronic topologies (double-bridge voltage sources inverter), cutting edge power semiconductor technology (gallium nitride), and multiobjective optimization techniques allow reducing the inverter size, increasing inverter efficiency, and improving the output current quality and in return lowering the losses in the electric motor. This enables the electrical, mechanical, and thermal integration of the inverter into the compressor housing of very high-speed and compact turbo compressors, thereby reducing the size and weight of the overall compressor system by a factor of two. Furthermore, a turbo compressor with an integrated inverter reduces complexity and cost for operators with savings in casing, cables, coolant piping, and connectors and reduces EMI noise by shielding the high-frequency motor currents with one housing. Beside its main application for fuel cell air supply, the advantages gained by an integrated inverter can also be used in other boosting and air handling applications such as advanced air and exhaust handling in combustion engines. The proposed integration concept is verified with a 280,000 rpm, 1 kW turbo compressor, targeted for the Balance of Plant (BoP) of a 5–15 kW fuel cell. The experimental results show that the temperature limits on the power electronics parts can be kept below the limit of 90 °C up to a coolant temperature of 55 °C, and beside the advantage of lower cabling effort, the efficiency of the compressor system (turbo compressor and integrated inverter) is increased by 5.5% compared to a turbo compressor without an integrated inverter.
