Primary intra-ventricular hemorrhage in 33-year-old man: a case report
Authors: Gunawan Stephanie E. , Putri Setyawati Asih
Published: June 2022

The aim of the study was to provide insight into cases of primary intra-ventricular hemorrhage caused by arterial venous malformations. A 33-year-old man visited the emergency room and admitted that he had a chief complaint of headache for the last 7 days. Neurological clinical examination only found nuchal rigidity. The CT scan of the head showed intra-ventricular hemorrhage and the CTA results showed an AVM with a left occipital nidus with arterialization of the posterior cerebral artery. One day before the DSA was performed, the patient had a seizure and based on a repeat CT scan, the bleeding spread to the parenchyma. The patient refused decompression and decided to go home after his condition stabilized and his complaints improved with anti-edema treatment. A repeat DSA action was planned but the patient had financial problems. Primary intra-ventricular hemorrhage occurs when the nidus arterial venous malformation is adjacent to the ventricle although this is only 7% of all cases of primary intra-ventricular hemorrhage. In the case of primary intra-ventricular hemorrhage, complications need to be wary of when hydrocephalus appears. In addition, digital subtraction angiography should be performed prior to endovascular surgery as the main modality of therapy. Arterial venous malformation can be one of the causes. Digital angiography and Endovascular measures should be performed in this patient to prevent further complications. However, the refusal of the patient and family until the time of this case report was made is a separate obstacle in the diagnostic and therapeutic process.

This research was to evaluate the effects of integrating T. diversifolia, P. guineense and OPBRA to manage Cylas puncticollis infestation and on the yield of sweet potatoes. Bioassay 1, 5g T. diversifolia + 5g P guineense /100mL and 10g P guineense /100mL showed significant low (P < 0.05) in mortality, number of eggs laid, percentage repellence and progeny emergence of C. puncticollis. Bioassay 2: 20 g OPBRA /100mL, 5g OPBRA + 5g P guineense /100mL, and 10g P guineense /100mL. The lowest progeny emergence was 5g OPBRA + 5g P guineense /100mL. 5g OPBRA + 5g P guineense /100mL, and 10g P guineense /100mL showed significant difference (P < 0.05) in mortality, mean number of eggs laid of C. puncticollis with the control. Bioassay 3 and 4: showed significant effect (P < 0.05) of T. diversifolia, OPBRA and P. guineense pastes on weight loss due and root sizes to C. puncticollis damage of sweet potato. On the field, sweet potatoes that were treated with 2 ton/ha T. diversifolia + 2 ton/ha OPBRA + 0.33 ton/ha P. guineense and 0.67 ton/ha P. guineense showed significantly (P < 0.05) less infestation than the other treatments. Plants treated with 2 tons/ha T. diversifolia +2 tons/ha OPBRA + O.33 tons/ha P. guineense had the highest yield. The combination of T. diversifolia, OPBRA and small proportion of P guineense could serve as an alternative of source of synthetic pesticides managing C. puncticolis infestation as well as source of organic matter improve soil fertility.
TRANSFORMATION OF THE SYSTEM OF PHYSICAL CULTURE AND SPORTS PRESS OF THE USSR AT THE TURN OF 1920S-1930S: STATISTICAL AND TYPOLOGICAL OVERVIEW
Authors: Alekseev Konstantin A.
Published: June 2022

The purpose of the presented article was to study the complex of reasons that caused significant quantitative and qualitative changes in the system of physical culture and sports printing in the USSR at the turn of the 192©0s-1930s. The relevance of addressing this topic is predetermined by the search for effective mechanisms for propaganda, organization and coverage of the mass sports movement. The main research method is historical and typological analysis, which allows revealing the general patterns of transformation of various types of physical education and sports publications in close relationship with the factors of political, economic and cultural life of Soviet society. Publications of periodicals about physical culture and sports, as well as archival documents related to the activities of leading sports organizations were taken as sources. As a result, a key factor in the transformation of the physical culture and sports press system was identified – the general restructuring of the Soviet physical culture movement, which led to a significant expansion of the audience, the setting of new tasks and the transformation of the typological image of the press. Further development of the physical culture and sports press in the 1930s followed the path of centralization and rigid planning.
CONTRAST IN E. POE’S POETRY
Authors: Boeva-Omelechko Natalya B.
Published: June 2022

The relevance of this work is due to the significance of E. Poe’s works for world literature and the constant interest of scientists in the peculiarities of his work, as well as the need to study the idiostyle features of the implementation of contrast in E. Poe’s poetry. The purpose of the work is to describe the types of contrast present in E. Poe’s poetry and the linguistic means of their implementation. The author suggests that contrast is one of the idiostyle dominates of E. Poe’s works of fiction. The assumption about the significance of contrast for the poetry of E. Poe is based on works in the field of literary criticism, which analyze his works and note that the general principle of Poe’s poetics is emotional and psychological influence on readers. An important role in the implementation of such influence belongs to contrast. According to the results of the analysis of empirical material, these types include microcontrast implemented in a separate fragment of the text, and macrocontrast, significant for the compositional and semantic structure of the entire work (the juxtaposition of the text and the title, the beginning and end, the beginning and the main part of the text, etc.). Microcontrast in Poe’s works is embodied by using system antonyms. The poet can use two antonymic oppositions in contact, which enhances the expressiveness of contrast. E. Poe also uses individual author’s antonyms, verbalizing in an unusual form conjugated concepts opposed to each other and correlating with the systemic antonymic opposition as well as antonyms belonging to different parts of speech. Macrocontrast is created either with words that are not system antonyms, but belong to contrasting semantic fields or with means of negation. Rather often the contrast is exclusively semantic without the participation of contrasting language means. The article describes different types of micricontrast typical of Poe’s works.

Authors: Priya R. Raja , Krishnan R. , Sabareeshwari V. , Sureshkumar R. , Chandran Deepak , Marthandan V.
Published: June 2022

Background: Cluster bean was cultivated as a catch crop without external fertilization, solely to recharge the soil fertility and to harvest the residual nutrient after maize crop; clusterbean had been included as a succeeding crop. Doubling the fertilizer for maize would leave more residues. Even though maize is an exhaustive crop, since the nutrient uptake was need based, the excess fertilizers were effectively utilized by cluster bean. Methods: A field research was carried out at Tamil Nadu Agricultural University, Coimbatore under irrigated conditions. Experimental trials were adopted to estimate the effect of high density with nutrient management practices on maize which influences the performance of succeeding cluster bean under maize-cluster bean cropping sequence during Rabi seasons of 2017-18 and 2018-19 by using cultivar Pusa Naubahar. No separate treatments were adapted to cluster bean crop. Result: The results of cluster bean sown after the high density of 1,33,333 plants ha-1 maize with nutrient level of 200 per cent RDF produced taller plants, higher drymatter production (636 and 607 kg/ha), increased yield attributes, higher yield (6.58 and 6.81 t/ha) and better economics (B:C ratio -1.87 and 1.94) in both the seasons. Post-harvest available nutrient status revealed that the higher population by closer spacing with increased fertilizer levels (T7) maintained its superiority during both the years. Moreover, this proved to be the most viable practice for production and residual nutrient uptake, by including pulse (cluster bean) as succeeding crop and soil health was effectively maintained by fixing atmospheric nitrogen by cluster bean.
Improving UAV Radio Control System with 433 MHz Radio Wave Using Lo-Ra based on QCZEK Model Communication System
Authors: Fadila Juniardi Nur
Published: June 2022

UAV must have a reliable control system considering the UAV is an unmanned vehicle that relies on human control on the ground. Most of control system used in UAVs uses a 2.4 GHz as it frequency. This frequency has disadvantaged for UAV because it is mainly used for Wi-Fi communication system so when users of UAV’s fly in urban areas where full of Wi-Fi system, there will be interference within UAV control system and Wi-Fi, so failsafe will often occur. From the theory, different frequencies produce different criteria for radiofrequency communication system to synchronize and manage and secure communication between transmitter and receiver. In this study, we will discuss the application of 433 MHz frequency for the control system for UAV. The goal of this research is to establish a reliable control system of UAV when used for the long-range mission. To make this control system, we use the Lo-Ra module with STM32 based Microcontroller designed for QCZEK TX/RX model communication. After several testing on the ground and the air, the purpose system serve 14 % longer distance than TBS system or market build system and 6 times longer distances than 2.4Ghz frequencies.

Published: June 2022

La traducción del castellano al quechua es una actividad que después de aproximadamente dos siglos ha ganado una vez más importancia en el Perú. En gran parte se debe a la promulgación de la Ley de Lenguas Indígenas del Perú, que establece que todo documento oficial debe estar traducido a la lengua del territorio donde se emita. Ante esto, el Estado decidió impartir programas de capacitación para traductores e intérpretes de lenguas originarias, entre ellas el quechua. Los traductores de quechua cumplen un rol importante en la sociedad y su labor es compleja por razones lingüísticas y culturales inherentes a esta lengua originaria. Sin embargo, existen muy pocos estudios que han investigado su proceso de traducción. En este contexto, el presente estudio cualitativo se ha enfocado en analizar las estrategias traslativas comunes y distintas de traductores castellano-quechua mediante estrategias establecidas por la traductología que sirven como instrumento de análisis para clasificarlas. Para ello, se realizaron entrevistas a siete traductores que residen en Lima. Los resultados reflejan que las estrategias más frecuentes son préstamos, filtros culturales, paráfrasis, neologismos con nuevo sentido, cambios en la estructura de la frase y naturalizaciones. Asimismo, se hallaron factores que los participantes consideraron para escoger sus estrategias: el receptor, la finalidad de la traducción, los requerimientos del cliente, la cultura y el contexto. Adicionalmente, se encontraron perspectivas comunes de los traductores al emplear dichas estrategias.

Published: June 2022

A dialogue between a government and society is the principal realization of which is declared in many of modern states. Though such dialogue can occur only when authorities make it possible for the mechanisms and channels of political feedback to function successfully which allows to identify, analyze, understand and take into account social demands and the current problematic field of the society while working out a political course.
In the era of digitalization when the new technologies continue to permanently change the basic spheres of the society this question has become more urgent. Political-administrative sphere is not an exception and today digital technologies of political participation and governmental services providing. Though the question to what extent these steps change the essence of policy, political governing and political regimes (primarily the democracies) and the dialogue between government and society. Particularly the statement that digitalization of the political-administrative process is a step towards establishing democracy of a new type raises doubts. The latter creates opportunities for fundamentally different significant opportunities for citizens to participate in public decision-making. For answering the question, the article looks into the nature and peculiarities of a social-governmental dialogue, the gist and the principals of democracy, the limits of modifying democracy towards factual increasing of the role of the society in taking part of political administrative decision making; the possibility of realization of the principles of a deliberative democracy is being considered.

Published: June 2022

Based on the data of the author's comparative sociological study conducted in 2019 in 4 countries (Russia, Poland, Italy, Germany), the author describes the life strategies of young people in the context of the current socio-economic situation and modern social policy. Young people were asked questions about the significance for them of various areas of their lives, about their self-identification and social well-being now and in the future for 10-15 years, their vision of the country's development and about how and what kind of future they plan for themselves.
The author shows that the level of social optimism of young citizens in 4 countries is associated with both objective indicators of social well-being and subjective ideas about their place on the social ladder.
Particular attention is paid to the consideration of planning horizons and prospects for their economic well-being, career growth, civic activity in connection with the possible future of the country. There is an acute sensitivity of young people in comparison with other demographic and social groups to events taking place in society.
The study of changes in youth assessments of their place in society, existing prospects, the structure of values makes it possible to trace the direction and speed of changes that are now taking place in the public consciousness. And also, to identify key values for society, not only transmitted from generation to generation, serving as a kind socio-cultural basis and national marker, but also changing, especially in the context of globalization and global transformation. As a result, this makes it possible to present the image of the future as it is seen by the current generation of young people.

The data used is secondary data in the form of journal articles used for publication in 2014-2021. The results showed that the stages during the Indonesia Islamic Bank (BSI) merger process started from the approval of the BRIS, BNIS, and BSM Board of Commissioners on the Merger Plan on October 20, 2020, until it officially started operating on February 1, 2021. In addition, the challenge for the Indonesia Islamic Bank (BSI) merger is the market share of the Islamic finance industry, which is still small or lagging compared to conventional banks. Thus, several strategies can be carried out by Indonesia Islamic Bank (BSI), starting from improving business processes, strengthening risk management, strengthening human resources (HR), in enhancing digital technology. The results of this study are expected to be input for Indonesian Islamic banks in particular to be able to determine the right strategy in dealing with mergers so that they can be a solution to the challenges that will be faced by Indonesian Islamic banks. In addition, the government, namely the Financial Services Authority (OJK) can coordinate with the Sharia Accounting Standards Board (DSAS) and the Indonesian Ulema Council (MUI) to supervise and assist in accelerating the development of Islamic banking.

Authors: Joko Santosa
Published: June 2022

The purpose of this study to gain an in-depth understanding of the role of audit for the welfare of the people. Qualitative tradition becomes a paradigm of study by using literature study as its methodology. The results of the analysis and discussion, the discourse is more strategically valuable if it is implemented in efforts to handle and minimize corruption. The argument that states that as a form of audit expectation gap, people's welfare is difficult to realize when corruption is still a serious problem that has not been resolved. The practical contribution of this research is to offer two strategic steps that BPK can take to reduce the existing expectation gap, firstly by improving the quality of financial audits, and secondly by focusing on performance audits with a higher priority on improving the quality of internal auditors' performance (APIP). In the theoretical realm, it can open up opportunities for the development of the concept of auditing in the public sector, not only serving scientific needs but also responding to public expectations.

Published: June 2022

We consider a model of three-core PIM-NIM-PIM coupler with Kerr-type saturable nonlinearity to study both analytically and numerically saturation effects on the modulational instability phenomenon. The analytical results show us that, in presence of saturable parameter in normal and anomalous dispersion regime it is formed some new instability bands compare to Shafeeque et al (2015) in absence of saturable parameter. It is clearly also show that Power and nonlinears parameters can be used to control MI. Through numerical simulation, the generation of periodic soliton with a growing amplitude are obtained in absence of nonlinear saturation. However in presence of saturable parameter the train of soliton obtained turns into a turbulent state after certain propagations distance.
Alternatives to chemical resistance: Combinations of Cymbopogon nardus and Ocimum americanum essential oils improve the bioefficiency control against the adults populations of Aedes aegypti L. (Diptera: Culicidae).
Authors: Gnankiné
Published: June 2022

Dengue vector control strategies are mostly based on chemicals use against Aedes aegypti populations. The current study aimed at investigating the insecticidal effects of essential oils obtained from five plant species, Cymbopogon citratus, Cymbopogon nardus, Eucalyptus camaldulensis, Lippia multiflora and Ocimum americanum, and combinations of Cymbopogon nardus and Ocimum americanum on Aedes aegypti populations from Bobo-Dioulasso. For this purpose, adults of the susceptible and field strains of Aedes aegypti were tested in WHO tubes with EO alone and binary combinations of O. americanum (OA) and C. nardus (CN) (scored from C1 to C9). The extraction of the essential oils was done by hydrodistillation and their components were determined by GC/MS. Among the 5 EOs tested, L. multiflora essential oil was the most efficient, with KDT50 values below 60 minutes on all Aedes aegypti strains tested, and also with a rate of mortality up to 100 and 85% for Bora Bora and Bobo-Dioulasso strains, respectively. This efficacy may be due to its major compounds which are with major compounds as ß-caryophyllene, p-cymene, thymol acetate and 1.8 cineol. Interestingly, on all strains, C8 combination showed a synergistic effect while C2 showed an additive effect. These combinations exhibit a rate of mortality varying from 80 to 100%. Their toxicity would be due to the major compounds and the putative combined effects of some major and minor compounds. More importly, L. multiflora EO and combinations of C. nardus and O. americanum EO, may be used as alternatives against pyrethroid resistants of Ae. aegypti.
Energy Aware Clustered Blockchain Data for IoT: An End-to-End Lightweight Secure & Enroute Filtering Approach
Authors: S Ramamoorthi , KUMAR MUTHU
Published: June 2022

Internet of things (IoT) include smart homes, smart buildings and smart factories, in which all the devices are connected over the internet throughwireless network for data transmission or sharing. IoT faces many security challenges due to sharing the data in an open source. Security and energy are the most focusing challenges in IoT due to its resource constrained nature. IoT devices have low energy that iswasted by the attackers, and the data also gets hacked by the attacker, which leads to poor security. This paper proposed CLIENT (Clustered blockchain IoT withEn-route) to provide energy efficient and secure communication. For that, this research proposed five processes. Such as Chaotic map based elagamal authentication, credit score based clustering, capuchin searh optimization based packets routing, singnature based Enroute filtering and deep leaning based anomaly packet detection.First process is Chaotic Map based Elgamal Authentication, in which chaotic map is used in Elgamalfor key generation. Second process isCredit score based clustering which minimizes the complexity and overhead during packet transmission. Third process is Capuchin search optimization based packets routing which is used to select optimal route from cluster member to cluster head (CH)..)Fourth process is signature based Enroute filtering which used to detect and drop false report from the network. Edwards signature based digital signature algorithm (EdDSA) is used for verification purpose. And final process is deep learning based anomaly packets detection, this process used Katz centrality based feed forward small world neural network (FFSWNN) for packet classification (normal or malicious). All the transactions are stored in blockchain to enhance security. The proposed system implemented by using NS3. The result shows that proposed system achieves superior performance compared to existing works in terms of energy consumption, packet loss rate, end to end delay, routing overhead and network life time, precision, recall, accuracy, false alarm rate, encryption time, decryption time and security strength.

Published: June 2022

Background
The exchange of microbes between humans and the built environment is a bidirectional and dynamic process that has significant impact on health. Most studies exploring the microbiome of the built environment have been predicated on improving our understanding of pathogen emergence, persistence, and transmission. Previous studies have demonstrated that SARS-CoV-2 presence significantly correlates with the proportional abundance of specific bacteria on surfaces in the built environment. However, in these studies, SARS-CoV-2 originated from infected patients. Here we perform a similar assessment for a clinical microbiology lab while staff were handling SARS-CoV-2 infected swab samples for RT-qPCR analysis. The goal of this study was to understand the distribution and dynamics of microbial population on various surfaces within different sections of a clinical microbiology lab during a short period of 2020 Coronavirus disease (COVID-19) pandemic.
Results
We sampled floors, benches and sinks in three sections of an active clinical microbiology lab (bacteriology, molecular microbiology, and COVID) over a 3-month period. Although floor samples harbored SARS-CoV-2, it was rarely identified on other surfaces, and bacterial diversity was significantly greater in floor samples than sinks and benches. The floor-associated microbiota comprised greater proportions of bacteria commonly associated with natural environments (e.g., soils), and benchtops harbored a greater proportion of human-associated microbes, including Staphylococcus and Streptococcus, which may have originated from either laboratory staff or clinical samples. Finally, we show that the microbial composition of these surfaces did not change over time and remained stable.
Conclusion
Despite of finding viruses on the floors, no lab-acquired infections were reported during the study period, which suggests that lab safety protocols and sanitation practices were sufficient to prevent pathogen exposures. Like other BEs and health care facilities the most common bacteria colonizing the surfaces in a clinical microbiology lab primarily consist of bacterial taxa of environmental and human origin. Although our analysis here does not identify the source of infection in any given case, it does help to elucidate microbes that colonize these surfaces and have the potential to cause LAIs.

Published: June 2022

Groundwater quality evaluation is among the most critical aspects of water management concepts. As a result of overexploitation due to overpopulation, groundwater is severely deteriorating. Water Quality Index (WQI) is commonly used to appraise groundwater quality. In the present study, WQI model is developed to evaluate the groundwater quality in north Khartoum area. To classify water quality for diverse reasons, WQI uses multiple asset classes, sub-indices, and an accumulation function. Multivariate statistical analyses were applied to test the correlation between different variables to draw on the main variables and processes affecting the groundwater quality in the study area. Furthermore, correlation analysis (CA) and principal component analysis (PCA) served as guide for weights assignment in WQI calculations and interpretation. The innovative statistically guided WQI models (SWQI) proved to be superior in groundwater quality assessment. Although SWQI models is powerful and effective tool in groundwater assessment, however, conventional computation is lengthy, time consuming and is often observed with enormous errors during the calculation of sub-indices. In this study, artificial intelligence techniques are applied to cope with these limitations. Multilayer perceptron (MLP) and support vector regression (SVR) models were used for prediction of WQI. The dataset was divided into two groups (ratio 80:20) for training and validation respectively. The predicted models were compared with actual models using four statistical criteria, namely mean square error (MSE), root mean squared Error (RMSE), mean absolute error (MAE), and coefficient of determination (R2). The obtained results revealed the robustness of the artificial intelligence in prediction of WQI in north Khartoum area. The developed approaches in this study shown to be advantageous in groundwater quality assessment.
Will the substitution of capital for labor aggravate the input of chemical fertilizer in agriculture? Analysis based on provincial panel data in China
Authors: Lei Zekui , Tu Taotao , Li Xia
Published: June 2022

Major changes have taken place in the structure of agricultural input factors in China, which will inevitably affect fertilizer input in agriculture. However, there is no consistent conclusion on the impact of capital and labor input on chemical fertilizer input. This paper applies directed acyclic graphs (DAGs) to clarify the backdoor path of capital and labor affecting fertilizer input. Using inter-provincial panel data, the dynamic panel system GMM method was adopted to examine the mechanism of factor substitution elasticity in determining the impact of agricultural capital-labor input on chemical fertilizer input. Results showed that agricultural labor and capital input are positively correlated with chemical fertilizer input, and the factor substitution elasticity has a negative regulatory effect in the progress of labor and capital input impact fertilizer input. From 1996 to 2018, the trend of capital replacing labor was obvious, and the growth ratio of capital input was much greater than the decrease ratio of labor input. Therefore, the increase in capital input and its substitution for labor is the main driver of the increase in fertilizer input. Meanwhile, the fertilizer-capital substitution elasticity decreased during the period 1996–2018, thus reinforcing the rise in fertilizer input caused by the increase in capital input. To reduce the agricultural pollution caused by the increase in chemical fertilizer input, it is very important to reverse the declining trend of fertilizer-capital substitution elasticity.

Published: June 2022

Purpose
Sleep quality is an important indicator of individual quality of life, which not only affects people's mental health but is also closely related to the occurrence of many diseases. Sleep disorders associated with diabetes in pregnancy (DIP) can greatly endanger the health of mothers and babies, and the relationship between their hazards and blood glucose levels is very close. This study explored the quality of sleep in patients with DIP while analyzing the clinical features and related factors of their sleep disorders.
Methods
From June 2020 to July 2021, a total of 693 patients diagnosed with diabetes in pregnancy (DIP) in Gansu Provincial Maternal and Child Health Hospital were used as the experiment group, including 626 patients with gestational diabetes mellitus (GDM) and 67 patients with pregestational diabetes mellitus (PGDM). At the same time, 709 non-DIP women were randomly selected as the control group. To obtain the general situation of the participants, the participants were surveyed using the Pittsburgh Sleep Quality Index (PSQI) and the STOP-Bang questionnaire. The differences in sleep quality and obstructive sleep apnea-hypopnea syndrome (OSAHS) were analyzed between the experiment group and the control group using rank and chi-square test, and the clinical features and related factors of sleep disorder were analyzed.
Results
Compared with the control group, the experiment group had a larger age, pre-pregnancy weight, body mass index (BMI), and large neck circumference (P < 0.05). The PSQI scores for sleep quality, sleep duration, sleep efficiency, sleep disorder, and daytime dysfunction were higher compared with the control group (P < 0.05). Specific analysis of the clinical features of sleep disorders found that the experimental group had higher scores compared with the control group in terms of difficulty falling asleep, ease of waking up at night or waking up early, poor breathing, cough or snoring effects, feeling hot, nightmares, pain and discomfort, and other events that affected sleep (P < 0.05). The analysis of the types of daytime dysfunction found that the experiment group scored higher in terms of frequently feeling sleepy and lack of energy to do things than the control group (P < 0.05). Analysis of STOP-BANG scores indicated that the proportion of patients with GDM or PGDM having fatigue, hypertension, BMI > 35 kg/m2, and neck circumference > 40 cm was higher than that of the control group (P < 0.05).
Conclusions
Patients with DIP had more sleep disorders and a higher risk of developing OSAHS than non-diabetic pregnant women. There may be some link between sleep quality and the onset of DIP. This study lays the foundation for further studies and provides new ideas for the prevention and treatment of DIP.

This study is done to examine the microbiota in thrombi retrieved from the middle cerebral artery after mechanical thrombectomy for symptomatic carotid plaque within 6 hours of an acute ischemic stroke. To evaluate their role in atherosclerosis, thrombi were submitted to next-generation sequencing for a bacterial signature. In these study we are describing allots of bacteria found in thrombus samples, which are associated with stroke. Enrollment of 14 Acute ischemic stroke (AIS) patients was done who underwent mechanical thrombectomy in which 72% (n = 10) male and 28% (n = 4) female. The patients' median age was 16.75 ± 3.68 year old, and they were all female. During the window of acute stroke with symptomatic carotid stenosis and blockage of the ipsilateral middle cerebral artery, all were submitted to mechanical thrombectomy. After mechanical thrombectomy we extracted the DNA from thrombus sample. The microbial composition of all samples was compared using 16S rRNA gene amplicon next-generation sequencing.All of the thrombi retrieved for bacterial DNA in qPCR from the fourteen patients who had thrombectomy for ischemic stroke were positive. The 14 thrombus samples included more than 30 microorganisms. large bacterial diversity was found in thrombus in ischemic stroke patients in this study, which also indicated that microbes present in thrombus also played role in formation of plaque and Bacteria have direct mechanisms such as acidification and local inflammation of the plaque milieu with lactobacillus, biofilm dispersion leading to inflammation with pseudomonas fluorescence, or enterococci, or indirect mechanisms such as Toll 2 like signalling by the gut microbiota, could all lead to thromboembolic and cause stroke. It justifies more research into the involvement of bacteria in thrombus formation in stroke pathophysiology and prognosis.
An improved blind Gaussian source separation approach based on generalized Jaccard similarity
Authors: Fu Xudan , Ye Jimin , E Jianwei
Published: June 2022

Blind source separation (BSS) consists of recovering the independent source signals from their linear mixtures with unknown mixing channel. As a momentous technical means of signal processing and analysis, BSS has been widely utilized in image recognition, feature extraction, biomedical engineering, etcetera. The existing BSS approaches rely on the fundamental assumption: the source signals are non-Gaussian, this limited the use of BSS seriously. To overcome this problem and the weakness of cosine index in measuring the dynamic similarity between signals, this study proposes the fuzzy statistical behavior of local extremum (FSBLE) based on generalized Jaccard similarity as the signal's feature to implement the separation of nonlinear chaotic Gaussian source signals. In particular, the imperialist competition algorithm is introduced to minimize the cost function which jointly considers the stationarity factor describing the dynamical similarity of each source signal separately and the independency factor describing the dynamical similarity between source signals. Simulation experiments on synthetic data verify the effectiveness and superiority of the improved BSS approach in terms of cross-talking error and root mean square error (RMSE) criterions.

The decline of Arctic sea ice concentration (SIC) plays an important role in Arctic amplification which influences Arctic ecosystem, midlatitude weather and climate. The Arctic SIC shows prominent interannual and interdecadal variability. Although the interdecadal variability of the Arctic SIC fluctuations is mainly linked to Atlantic Multidecadal Oscillation, it is unclear what is the origin of the interannual variability of Arctic SIC. Here, we indicate that the interannual variability of Arctic SIC over Barents-Kara Seas (BKS) mainly originates from the remote modulation of El Niño-Southern Oscillation (ENSO) via the Atlantic pathway. It is revealed that La Niña (El Niño) can strengthen (weaken) the positive winter North Atlantic Oscillation (NAO+)-like circulation via enhanced (reduced) Atlantic Hadley cell to result in a notable Atlantic interannual variability (AIV). During the positive phase of AIV the enhanced transport of warm Atlantic water and warm moisture toward the BKS due to intensified winter NAO+-like circulation promotes the SIC decline over BKS through the presence of Ural blocking with NAO+. The reversed is seen during the negative phase of AIV. These new findings can help understand what is the origin of the interannual variability of winter sea ice over the BKS.

A recurring issue with microstructure studies is specimen lighting. In particular,microscope lighting must be deployed in such a way as to highlight biologicalelements without enhancing caustic effects and diffraction. We describe herean analysis of the potential of diffractive optic approaches for addressing thislighting issue. First, an extensive study is undertaken concerning asymptoticequations in order to identify the most promising algorithm for 3Dmicrostructure analysis. Ultimately, models based on virtual light rays arediscarded in favor of a model that considers the joint computation of phase andirradiance. This paper maintains the essential goal of the study concerningbiological microstructures but offers several supplementary notes oncomputational details which provide perspectives on analyses of thearrangements of numerous objects in biological tissues.

Background Physiotherapists deliver evidence-based guideline recommended treatments only half of the time to patients with musculoskeletal conditions. Physiotherapist’s behaviours in clinical practice are influenced by many cognitive, social and environmental factors including time and financial pressures. Many initiatives aimed at improving physiotherapists’ uptake of evidence-based care have failed to appreciate the context involved in clinical decisions and clinical practice. Therefore, we aimed to describe: i) the opinions of regional physiotherapists toward evidence in relation to their clinical decision making; ii) how regional physiotherapists access evidence; iii) the factors influencing regional physiotherapists’ evidence access; iv) the factors influencing regional physiotherapists’ evidence application.MethodsWe used a mixed-methods study with online survey and focus groups. Quantitative and qualitative data were used to inform all research objectives. We used eight domains of the Transtheoretical Domains Framework to design survey questions. We analysed quantitative and qualitative data in parallel, then integrated both sources through by developing a matrix while considering the Transtheoretical Domains Framework domains to generate themes. Results57 physiotherapists participated in the study (survey only n = 41; focus group only n = 8; both survey and focus group n = 8). Participants reported that evidence was important, but they also considered patient expectations, colleagues’ treatment choices, and business demands in clinical decision making. Physiotherapists reported they access evidence on average 30 minutes or less per week. Accessing evidence may not be prioritised among competing demands like business administration. Participants reported that patient expectations were a major barrier to applying evidence-based care. Environmental and systemic factors, like funding structures or incentives for evidence-based care, and social factors, like lacking or having a culture of accountability and mentorship, were reported as both barriers and enablers to evidence application.ConclusionsIn this study, we provide a description of contextual considerations for the provision of evidence-based care and suggest some potentially modifiable targets for future strategies aimed at improving evidence uptake. Physiotherapist’s provision of evidence-based care may be improved by enhancing structural support from workplaces to access and apply evidence and exploring discrepancies between physiotherapists’ perceptions of patient expectations and actual patient expectations.
Large deviation principle for stochastic heat equation with general rough noise
Authors: Li Ruinan , Wang Ran , Zhang Beibei
Published: June 2022

Please see Manuscript PDF for complete Abstract with equations:We study Freidlin-Wentzell's large deviation principle for one dimensional nonlinear stochastic heat equation driven by a Gaussian noise: $$ \frac{\partial u^{\e}(t,x)}{\partial t}=\frac{\partial^2 u^{\e}(t,x)}{\partial x^2}+\sqrt{\e}\sigma(t, x, u^{\e}(t,x))\dot{W}(t,x),\quad t> 0,\, x\in\RR, $$ where $\dot W$ is white in time and fractional in space with Hurst parameter $H\in(\frac 14,\frac 12)$. Recently, Hu and Wang ({\it Ann. Inst. Henri Poincar\'e Probab. Stat.} {\bf 58} (2022) 379-423) studied the well-posedness of this equation without the technical condition of $\sigma(0)=0$ which was previously assumed in Hu et al. ({\it Ann. Probab}. {\bf 45} (2017) 4561-4616). We adopt a new sufficient condition proposed by Matoussi et al. ({\it Appl. Math. Optim.} \textbf{83} (2021) 849-879) for the weak convergence criterion of the large deviation principle.
