Authors: Gabova M A , Nikolsky O K , Shlionskaya Yu D 
Published: January 2022

Abstract
The article considers approaches to the formation of a system of criteria for assessing the electrical installations fire condition of the agricultural and industrial complex. Based on the analysis of the literature, the conclusion is made about the appropriateness of the use of expert assessments. To implement the decision, a group of experts was assembled, on the basis of whose knowledge a list of 42 parametersζ characterizing the fire condition of the electrical installation was determined. To identify the relationships and form a method for calculating the estimated value of fire risk, experts assessed the fire condition of 70 electrical installations of the agricultural and industrial complex of the region. A knowledge base was formed from the resulting values. As a method of data analysis, it was decided to use neural networks, but the available sample is not sufficient for high-quality training of a neural network. Therefore, the correlation method and the principal component method were considered, and based on the calculations, it was decided to use a training sample consisting of 6 principal components for training a neural network. A neural network was trained on these data and the values of the average error were obtained sufficiently low, which may indicate sufficient accuracy of the generated model. The article also presents a conceptual scheme of a software package for automating calculations in accordance with the developed model.

Abstract
Agriculture is a socially significant sector of the economy. The growth of agricultural production contributes to the stable development of society. It is necessary to use new mechanisms driven by induction motors to increase agricultural productivity. Three-phase induction motors are mainly used in the electric drive of agricultural machines. At the same time, it is advisable to use a single-phase network to supply power to remote farms. In this regard, the development of a single-phase electric drive using three-phase motors becomes relevant. In this work, a study of an original semiconductor device for starting a three-phase induction motor from a single-phase network is made. The simulation model of the device created in the Matlab Simulink environment made it possible to study the electromechanical characteristics of the induction motor when operating from a single-phase network. A comparison of the characteristics of the motor during operation from a three-phase and a single-phase network is carried out. The most significant results of the work are the data obtained that the developed device can be used to start and operate a squirrel cage induction motor from a single-phase network. At the same time, the engine energy parameters change slightly.

An electroresistive method for monitoring the technical state the rolling support is proposed, which differs from the known methods by original algorithms for collecting information about the state of bearing parts, experimental studies have been carried out to confirm the efficiency of this method.
Ultranarrow dual-band metamaterial perfect absorber and its sensing application
Authors: Zhao Wenhan , Wang Junqiao , Li Ran , Zhang Bin 
Published: January 2022

Abstract
In this paper, a dual-band metamaterial absorber (MMA) with wide-angle and high absorptivity is proposed. The MMA consists of two silver layers separated by a dielectric layer. Its top resonant element is constituted by two concentric ring resonators connected with four strips. Based on electromagnetic field simulation, the proposed MMA has two narrow absorption peaks with an absorption rate of 99.9% at 711 nm and 99.8% at 830 nm, and the corresponding line width of the two absorption peaks are only 9.7 and 9.8 nm. The dual-band MMA shows high absorptivity under wide incident angles. The simulated field pattern shows that dual-band perfect absorption is the combined result of the interaction of two concentric ring resonators and unit cell coupling. In addition, the hexapole plasmon mode can be observed at the outer ring at one absorption peak. The narrow plasmon resonance has a potential application in optical sensing, and can be used to measure the concentration of aqueous glucose with two frequency channels. The proposed MMA with high absorptivity is simple to manufacture, and has other potential applications, such as narrow-band filters, energy storage device, and so on.

Authors: Pramounmat Nuttanit , Yan Katherine , Wolf Jadon , Renner Julie 
Published: January 2022

Abstract
Platinum-binding peptides have been used for fabrication of complex platinum nanomaterials such as catalysts, metallopharmaceuticals, and electrodes. In this review, we present understanding of the mechanisms behind platinum-binding (Pt-binding) peptides and the applications of the peptides as multifunctional biomaterials. We discuss how the surface recognition, the roles of individual amino acids, and arrangement of amino acid sequences interplay. Our summary on the current state of understanding of Pt-binding peptides highlights opportunities for interdisciplinary research which will expand the applicability of these multifunctional Pt-binding peptides.
The Aesthetic Theory of Frances Power Cobbe
Authors: Stone Alison 
Published: January 2022

Abstract
This article contributes to recognizing and recovering women’s voices in the history of aesthetics by examining the aesthetic theory put forward in the 1860s by the Anglo-Irish philosopher and feminist Frances Power Cobbe. Cobbe addressed aesthetics and gender, maintaining that there are female geniuses. She addressed art and morality, arguing that art should always aim to express moral truth, and that artworks that express morally good thoughts poorly are artistically better than works that express morally bad thoughts well. She then modified her stance to argue that beauty contains but does not reduce to goodness. Cobbe also developed a comprehensive account of the arts, their relative merits, and the criteria for evaluating them. Her account had problems; nonetheless, it was ambitious, original, and interesting, and Cobbe deserves to be recognized as a woman who made significant interventions in the history of aesthetics.
The dream of recapture
Authors: Nicolai Carlo 
Published: January 2022

Abstract
As a response to the semantic and logical paradoxes, theorists often reject some principles of classical logic. However, classical logic is entangled with mathematics, and giving up mathematics is too high a price to pay, even for nonclassical theorists. The so-called recapture theorems come to the rescue. When reasoning with concepts such as truth/class membership/property instantiation, (These are examples of concepts that are taken to satisfy naive rules such as the naive truth schema and naive comprehension, and that therefore are compatible with a solution to paradox cast in the logics considered below. Other notions of similar kind can be added to the list.) if one is interested in consequences of the theory that only contain mathematical vocabulary, nothing is lost by reasoning in the nonclassical framework. This article shows that this claim is highly misleading, if not simply false. Under natural assumptions, some well-established approaches to recapture are incorrect.
‘Block, Unfollow, Delete’: The Impacts of the #BlackLivesMatter Movement on Interracial Relationships in Australia
Authors: Gatwiri Kathomi , Townsend-Cross Marcelle 
Published: January 2022

AbstractInterracial relationships are situated historically within a complex racial discourse. At the height of the #BlackLivesMatter Movement in 2020, interracial relationships were tested, broken and repaired, whilst others were unable to withstand the racial destabilisation summoned by the Movement. In this article, we theorise how Blac/k bodies are organised and structured within systems of racial hierachialisation and the impact of this within relational contexts. Probing concepts of silence, fragility and allyship, which underpin the white racial frame, we provide critical argumentations of how processes of racialisation impact personal relationships where variables of blackness and whiteness are produced as sites of racial contestation. We argue that the political significance of race enters interracial relationships and theoretically transforms them into racial battlegrounds.

Abstract
Demyelination of the central nervous system is a prominent pathological hallmark of multiple sclerosis and affects both white and grey matter. However, demyelinated white and grey matter exhibit clear pathological differences, most notably the presence or absence of inflammation and activated glial cells in white and grey matter, respectively. In order to gain more insight into the differential pathology of demyelinated white and grey matter areas, we micro-dissected neighbouring white and grey matter demyelinated areas as well as normal-appearing matter from leucocortical lesions of human post-mortem material and used these samples for RNA sequencing. Our data show that even neighbouring demyelinated white and grey matter of the same leucocortical have a distinct gene expression profile and cellular composition. We propose that, based on their distinct expression profile, pathological processes in neighbouring white and grey matter are likely different which could have implications for the efficacy of treating grey matter lesions with current anti-inflammatory-based multiple sclerosis drugs.
Input–output efficiency model of urban green-energy development from the perspective of a low-carbon economy
Authors: Wu Hongliang , Wang Ling , Peng Daoxin , Liu Benjie 
Published: January 2022

Abstract
With the acceleration of urbanization, cities are the main targets for carbon neutrality and urban energy is the terminal of energy consumption and the integration point of various energy systems. Therefore, there is a need to promote the development of urban green energy and achieve low input and high output to achieve a low-carbon economy in cities. Previous studies have not considered the input–output efficiency of urban green-energy development. This study fills this gap. Based on the economic–energy–environmental framework, an input–output efficiency-evaluation index system for urban green-energy development was constructed. Based on improved data-envelopment analysis, a comparative evaluation of the input–output efficiency of green-energy development was carried out in 30 provinces in China in 2019. Considering the differences in regions, the development of urban green energy in different provinces was classified. From the perspective of a low-carbon economy, economic growth factors and environmental constraint factors were set. Together with the generalized Divisia index approach, the input–output efficiency optimization directions of urban green-energy development were obtained. The results showed that the input–output efficiencies of urban green-energy development in Jiangsu, Zhejiang, Fujian, Inner Mongolia, Ningxia and other provinces and cities were relatively high. Provinces with faster economic development and higher environmental carrying capacity have advantages after optimization and will become pilot areas for the development of urban green energy. This research provides a reference for the development of urban green energy in various provinces from the input and output perspective.
Rhythmic activation of excitatory neurons in the mouse frontal cortex improves the prefrontal cortex–mediated cognitive function

Published: January 2022

Abstract
The prefrontal cortex (PFC) plays essential roles in cognitive processes. Previous studies have suggested the layer and the cell type–specific activation for cognitive enhancement. However, the mechanism by which a temporal pattern of activation affects cognitive function remains to be elucidated. Here, we investigated whether the specific activation of excitatory neurons in the superficial layers mainly in the PFC according to a rhythmic or nonrhythmic pattern could modulate the cognitive functions of normal mice. We used a C128S mutant of channelrhodopsin 2, a step function opsin, and administered two light illumination patterns: (i) alternating pulses of blue and yellow light for rhythmic activation or (ii) pulsed blue light only for nonrhythmic activation. Behavioral analyses were performed to compare the behavioral consequences of these two neural activation patterns. The alternating blue and yellow light pulses, but not the pulsed blue light only, significantly improved spatial working memory and social recognition without affecting motor activity or the anxiety level. These results suggest that the rhythmic, but not the nonrhythmic, activation could enhance cognitive functions. This study indicates that not only the population of neurons that are activated but also the pattern of activation plays a crucial role in the cognitive enhancement.
Coronary intervention for severe stenosis in the ostial right coronary artery with cardiac angiosarcoma: a case report
Authors: Hirai Tadayuki , Miwa Kenji , Furusho Hiroshi , Yasuda Toshihiko 
Published: January 2022

Abstract

Background
Although rare, angiosarcoma is the most common type of cardiac primary malignancy. This disease can cause life-threatening complications and the prognosis remains poor. There is no standard approach to care, and clinical judgement is exercised on a case-by-case basis. Tumour progression causes serious complications, such as heart failure and vascular disruption.

Case summary
A 64-year-old Japanese woman presenting with a right atrial tumour was referred to our department. Tumour biopsy revealed that the patient suffered from angiosarcoma. We performed a lumpectomy to excise the tumour, but due to tissue adhesions in and around the right atrium, the malignancy could not be completely removed. After 3 years of chemotherapy, the patient was admitted to our hospital with increased chest pain. Emergency coronary angiogram revealed severe stenosis of the ostial right coronary artery. Intravascular ultrasound (IVUS) and computed tomography suggested coronary compression due to cardiac angiosarcoma. In this study, we report a unique case of advanced cardiac angiosarcoma, presenting as unstable angina, which was successfully treated with percutaneous coronary intervention using stent implantation.

Discussion
Due to the rarity of cardiac primary angiosarcoma, many symptoms are misdiagnosed until mechanical complications arise, such as coronary compression. The clinical course and various imaging modalities are useful for differentiating angiosarcomas from coronary stenosis.
Intravascular leiomyomatosis with cardiac extension: a case report
Authors: Shaked Einat , Sharoni Ram , West Debra Gershov , Lev Eli I 
Published: January 2022

Abstract

Background
Intravascular leiomyomatosis (IVL) with intracardiac extension is a rare benign tumour seen exclusively in women, characterized by proliferation of uterine smooth muscle cells through the venous circulation into the inferior vena cava (IVC) and the right heart chambers.

Case summary
A 47 years old women with history of previous hysterectomy due to myomatosis, presented with nausea, anorexia, and bilateral lower limb swelling over the preceding 2 months. An outpatient abdominal ultrasound discovered a mass in the IVC. Echocardiogram and computed tomography demonstrated a large intravascular mass extending from the pelvis to the right heart chambers. The tumour was completely removed in a concomitant open-heart surgery and laparotomy. Post-operative course was uncomplicated. A month later, the patient was feeling well and in good clinical condition. The histological analysis consisted with IVL.

Discussion
Intracardiac leiomyomatosis is a rare clinical condition which requires high index of suspicion. Multimodality imaging is usually required to establish the preoperative diagnosis, although the final diagnosis is achieved with tissue investigation. Complete surgical resection of the tumour is curative and associated with good long-term prognosis.
Giant coronary fistula aneurysm presenting as a progressing left-sided asymptomatic mediastinal mass with systolic dominant Doppler flow: a case report
Authors: Maruyama Hidekazu , Habe Kumiko , Kato Jo , Nishikii Makiko 
Published: January 2022

Abstract

Background
Cases of giant coronary artery aneurysms (GCAAs) associated with coronary fistula are rarely reported, and they present with various symptoms, including coronary steal syndrome. We report an uncommon case of an asymptomatic giant coronary fistula aneurysm presenting as a progressing left-sided mediastinal mass that has been tracked for years.

Case summary
A 67-year-old healthy asymptomatic woman was referred to our hospital because of an abnormal shadow on her chest radiography revealing a left-sided mediastinal mass that had progressed in size over the past 4 years. Computed tomography revealed mass progression from 4 to 5 cm in diameter within 2 years. Coronary computed tomography and coronary angiography identified a GCAAs in a coronary fistula originating in the left anterior descending artery and draining into the main pulmonary artery. Transthoracic Doppler echocardiography revealed a unique systolic dominant flow. She underwent coronary artery aneurysmectomy and fistula ligation. The patient has been in good health without any events for 10 months since her discharge.

Discussion
A GCAAs in a coronary fistula can present as an asymptomatic left-sided mediastinal mass that has progressed in size for years in older adults. Echocardiography can provide clues of the steal phenomenon in coronary artery fistula. A close investigation of mediastinal abnormalities can facilitate the detection of coronary aneurysms.

Abstract

OBJECTIVES
The aim of this study was to evaluate the surgical outcome of patients suffering from native aortic valve (NVE) or prosthetic aortic valve endocarditis (PVE) treated with the EDWARDS INTUITY Elite rapid-deployment valve prosthesis.

METHODS
Between February 2019 and June 2020, 25 patients suffering from NVE (n = 9; 36%) and PVE (n = 16; 64%) of the aortic valve received an INTUITY valve at our institution. Preoperative, operative and follow-up data were collected.

RESULTS
In our cohort, the mean EuroSCORE II was 13.4%. Eleven patients (44%) received concomitant aortic root patch plasty. Four patients (16%) received coronary artery bypass graft surgery, 3 patients (12%) received mitral valve repair and 2 patients (8%) underwent replacement of the ascending aorta. The cardiopulmonary bypass and aortic cross-clamp times were 124 ± 56 and 75 ± 39 min, respectively. The mean intensive care unit stay was 5 days. The mean size of the implanted prostheses was 25 ± 2 mm and the mean prosthesis transvalvular gradient 3 months after surgery was 9 ± 4 mmHg. During follow-up, no case of recurrent endocarditis occurred, 1 patient died of multisystem organ failure which had already been present preoperatively.

CONCLUSIONS
Surgery for NVE and PVE of the aortic valve may be safely performed using the EDWARDS INTUITY Elite valve system. This procedure could be well implemented in cases with extensive infection, fragile root tissue and root abscesses requiring root reconstruction. In our institution, the rapid-deployment aortic valve replacement strategy has become an important tool in the armamentarium of the surgical endocarditis treatment.

Abstract
Multidrug-resistant (MDR) Escherichia coli in food animals such as chickens is an emerging public health concern in Zambia. Additionally, the country's high demand for poultry products necessitates further investigation into the link between poultry and human MDR E. coli. Twenty cefotaxime-resistant E. coli isolates collected from poultry in Lusaka, Zambia, were screened for multidrug resistance and sequenced on MiSeq and MinION platforms. Genomes were assembled de novo and compared to 36 previously reported cefotaxime-resistant E. coli isolates from inpatients at the University Teaching Hospital, Lusaka. All (20/20, 100%) poultry isolates exhibited resistance to ampicillin, chloramphenicol, and doxycycline. Phylogenetic analysis and hierarchical clustering showed a high degree of genetic relatedness between E. coli O17:H18-ST69 from poultry and humans. The E. coli O17:H18-ST69 clone accounted for 4/20 (20%) poultry- and 9/36 (25%) human-associated isolates that shared two plasmids harboring 14 antimicrobial resistance (AMR) genes. However, comparison analysis showed that the isolates also had other AMR plasmids distinct for each niche. Our results suggested clonal transmission of MDR E. coli between poultry and humans, with the potential acquisition of niche-specific AMR plasmids. Thus, the control of MDR E. coli requires a One Health approach involving both human and animal health sectors.
