Electricity Network Security Monitoring Based on Bee Colony Algorithm
Authors: Su Wenzhi , Zhang Baolong
Published: September 2022

In order to effectively detect and discover network threats in the initial stage, this study proposes an electricity network security intrusion detection method based on feature selection. A heuristic feature selection algorithm based on the bee colony algorithm is proposed to overcome the shortcomings of existing feature evaluation methods. The algorithm uses average mutual information to measure the importance of features and more truly reflects the relationship between the selected features, the selected features, and the classification labels. Aiming at the problem that the algorithm is easy to fall into local optimization, a heuristic random search algorithm is proposed, which iteratively optimizes to generate smaller feature subsets, and improves the speed and accuracy of intrusion detection. The experimental results show that compared with the traditional algorithm, the proposed method can effectively evaluate the risk of attack path on the selected experimental data set, and the gap between the generation strategy and the optimal strategy is reduced by 71.3%, which enhances the practicability of the attack graph analysis method in a large-scale network environment. Conclusion. This method has good scalability and can be applied to large-scale network environments. It can effectively obtain attack paths that are more in line with the real threat situation in an acceptable time, so as to effectively find the network threats.

Combining two types of fibers may aid in improving the fundamental properties of organic fiber‐reinforced hybrid polymeric materials. Biomaterials created from raw materials are gaining appeal in the industrial sector due to their high quality, as well as sustainability and environmental considerations. Natural fiber‐reinforced hybrid nanocomposites were created in this work using a compression moulding technique with wood particles, hemp fiber, polypropylene, and montmorillonite nanoclay. Following that, the impacts of fiber mixture and vermiculite on mechanical and compostable qualities were studied. Both the coir and the hemp fibers were alkali‐treated to minimize their hydrophilic nature before even being employed. Using universal tensile testing equipment, the mechanical characteristics of the prepared composites were investigated and found to be improved following fiber blending and nanoparticle inclusion. The maximum strength was occurred at the combinations like 10 wt. % of wood particle, hemp, nanoclay, and 70% of polypropylene matrix. Scanning electron microscopy showed that nanoclay significantly increased the adherence and interoperability between fiber and the polymer matrices. The good biocompatibility and water absorption capabilities of the nanocomposite were increased by mixing fibers, but nanoparticle additions seemed to have the opposite impact.

Authors: Long Dan , Xie Yulu , Wei Yalong , Zheng Jie
Published: September 2022

There is more and more digital entrepreneurship emerging in practice, but research on it is rare and scattered, meaning that a review of digital entrepreneurship is important and necessary. Based on a data set covering 19 years of research, from 2003 to 2021, this article reviews 469 available articles from the Web of Science Core Collection. Using a scientific knowledge map, it divides digital entrepreneurship research into two stages, namely the “emerging stage” (2003–2017) and the “booming stage” (2018–2021). Research developed slowly in the emerging stage, focusing on the definition of digital entrepreneurship, the influence of digital technology, and antecedents of digital entrepreneurship. In the booming stage, however, digital entrepreneurship research grew explosively. This article sorts out the topics from three aspects, that is, organizational behavior, digital entrepreneurial ecosystem, and business model innovation. Longitudinal research, multi-case studies, mixed methods, and quantitative studies become mainstream, replacing the earlier single-case studies and conceptual analyses. The frontiers of research on digital entrepreneurship focus on digital entrepreneurial ecosystems, business model innovation, digital academic entrepreneurship, digital transformation, and the antecedents of digital entrepreneurship. This article proposes four future directions, including the interaction of digital entrepreneurship elements, the process of digital entrepreneurship with a dynamic perspective, digital entrepreneurship research at the community level, and digital entrepreneurship research in different contexts.

Published: September 2022

Nowadays, the banks are facing increasing business pressure in loan allocations, because more and more enterprises are applying for it and financial risk is becoming vaguer. To this end, it is expected to investigate effective autonomous loan allocation decision schemes that can provide guidance for banks. However, in many real-world scenarios, the credit status information of enterprises is unknown and needs to be inferred from business status. To handle such an issue, this paper proposes a two-stage loan allocation decision framework for enterprises with unknown credit status. And the proposal is named as TLAD-UC for short. For the first stage, the idea of deep machine learning is introduced to train a prediction model that can generate credit status prediction results for enterprises with unknown credit status. For the second stage, a dynamic planning model with both optimization objective and constraint conditions is established. Through such model, both the profit and risk of banks can be well described. Solving such a dynamic planning model via computer simulation programs, the optimal allocation schemes can be suggested.

Authors: Zhang Di
Published: September 2022

Table tennis forehand fast attack and loop technology is the core technology of the project, and table tennis footwork is directly related to the technical level and development prospects of athletes. However, it is very difficult to study technical issues such as the footwork of table tennis. This paper mainly studies the table tennis movement analysis and strength monitoring system based on the posture sensor. This article introduces the improved BP neural network algorithm of Secure Internet of Things. The dynamic error compensation of the sensor is verified by experiments. In the prediction stage, the system uses the estimated value of the previous state as the input value to estimate the current state. In the calibration stage, the output data of the current state can be used as the prediction data of the next state to get more accurate output value. MATLAB is used to read the data, the sampling frequency is 50 Hz, and the acceleration and angular velocity data are output at the same frequency. Finally, the flight trajectory of table tennis is predicted. The difference between the actual velocity and the carrier is about 0.07 m/s, and the actual displacement is about 0.45 m. The results show that the attitude sensor plays a good role in monitoring the movement track and serving strength of table tennis.

Published: September 2022

An area of medical science, that is, gaining prominence, is DNA sequencing. Genetic mutations responsible for the disease have been detected using DNA sequencing. The research is focusing on pattern identification methodologies for dealing with DNA-sequencing problems relating to various applications. A few examples of such problems are alignment and assembly of short reads from next generation sequencing (NGS), comparing DNA sequences, and determining the frequency of a pattern in a sequence. The approximate matching of DNA sequences is also well suited for many applications equivalent to the exact matching of the sequence since the DNA sequences are often subject to mutation. Consequently, recognizing pattern similarity becomes necessary. Furthermore, it can also be used in virtually every application that calls for pattern matching, for example, spell-checking, spam filtering, and search engines. According to the traditional approach, finding a similar pattern in the case where the sequence length is ls and the pattern length is lp occurs in O (ls

∗

lp). This heavy processing is caused by comparing every character of the sequence repeatedly with the pattern. The research intended to reduce the time complexity of the pattern matching by introducing an approach named “optimized pattern similarity identification” (OPSI). This methodology constructs a table, entitled “shift beyond for avoiding redundant comparison” (SBARC), to bypass the characters in the texts that are already compared with the pattern. The table pertains to the information about the character distance to be skipped in the matching. OPSI discovers at most spots of similar patterns occur in the sequence (by ignoring è mismatches). The experiment resulted in the time complexity identified as O (ls. è). In comparison to the size of the pattern, the allowed number of mismatches will be much smaller. Aspects such as scalability, generalizability, and performance of the OPSI algorithm are discussed. In comparison with the hamming distance-based approximate pattern matching algorithm, the proposed algorithm is found to be 69% more efficient.
Numerical Simulation on Dynamic Response of Existing Tunnel to Moving-Axle Loads under the Influence of Oblique Shield Crossing the Intersection Area
Authors: Jiang Pengcheng , Zhang Mengxi , Jia Wurong , Wei Hui , Javadi Akbar A
Published: September 2022

A 3D dynamic finite element model is developed to study the response of the existing tunnels’ concrete structure under the influence of different train speeds and undercrossing with fixed shield excavation. The intersection area of Metro Line 3 in Guangzhou and the intercity railway between Foshan and Dongguan is used as the case study. A programming idea simulating oblique moving-axle loads in the numerical model by using function expressions to constrain activity area is proposed. The Hilber–Hughes–Taylor time-integration scheme is used to calculate the dynamic response parameters of the double-channel rectangular cross section tunnels. Considering fixed excavation steps in the process of shield crossing, acceleration and deformation of the existing tunnels were analyzed under the moving-axle loads of trains at different speeds. From the perspective of the vibration and deformation of existing tunnels, shield excavation and moving speed have their own emphasis on the dynamic influence of the existing tunnel. In addition, the calculation results of the numerical simulation are in good agreement with the data obtained from some field tests, which further verifies the reliability of the calculation method of the numerical model. The results of this research can guide the arrangements for reinforcement measures for existing tunnels in the later stage.
Text Feature Extraction and Representation of Chinese Mental Verbs Based on Deep Learning
Authors: Wang Yongxue , Chuan Tee Boon
Published: September 2022

There are some problems in feature extraction and representation of Chinese mental verbs, such as low accuracy and low efficiency. In order to further improve the computational efficiency and accuracy of Chinese mental verb text, based on deep learning theory, activation function and damage function were used to optimize the original model. Considering the calculation method of model gradient, the optimization model describing the characteristics of Chinese mental verbs is finally obtained. The model can be used to analyze the variation of the characteristic parameters of Chinese verbs and the method of representation. Finally, the model error is analyzed by the method of comparative verification. Relevant studies show that the number of outputs and output results corresponding to softmax function will influence the test results of the model. By comparing the curves, it can be seen that the curve corresponding to the output number has an obvious increasing trend, while the corresponding output result curve has an opposite changing trend. The linear and nonlinear characteristics of the two curves are obvious. The real value of the mean square error function shows a change of linear increase, while the corresponding output value shows a change trend of gradual decline, which indicates that the two kinds of data have different influences on the model under related algorithms. It can be seen from the error data that the gradual increase of independent variables will improve the accuracy of the test results. Five different Chinese mental verb parameters have different manifestations in the deep learning model: among them, declarative verbs fluctuate in a small range and have little corresponding influence. However, the fluctuation of nondeclarative verbs and positive and negative declarative verbs is relatively small, and the curve is relatively stable. Negative verbs have a positive influence on the test output. Double negative verbs have negative effects. Finally, the accuracy of the model is verified by calculating the difference between experimental data and model data. This research can provide theoretical support and model verification method for the application of deep learning model in other fields of Chinese language.

Published: September 2022

Water pollution has been a major issue across the globe because of industrial activities to meet the needs of people. Many chemicals are released into the environment through these processes, which affect human health and the environment. Hence, the study aimed to assess the concentration of heavy metals (Cu, Zn, Mn, Ni, Hg, and Fe) and the physicochemical and biological properties of the Dankra River. The samples were taken from three locations, Konyaw, Jumako, and Anwiankwanta, and subjected to standard laboratory tests using Atomic Absorption Spectroscopy (AAS) and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). Results revealed that the Dankran river was not polluted with the selected heavy metals under study. The physicochemical properties, the biological oxygen demand (BOD), chemical oxygen demand (COD), and nitrogen, phosphorus, and potassium (NPK) concentrations were all within the allowable healthy limits according to WHO standards. Iron was the predominant metal in the Dankran river, with the highest concentration of 6.5913 mg/l. Thus, the river is safe to use, but there is a need for regular monitoring to support life. The order of concentration of the investigated metals follows this pattern in descending order: Fe > Mn > Cu > Zn > Ni > Hg.

Published: September 2022

In this paper, the dynamic modelling of a new configuration spacecraft is investigated. The significance of dumbbell-shaped spacecraft to deep space exploration and the configuration of dumbbell-shaped spacecraft are introduced firstly. Then, the vibration problem of the dumbbell-shaped spacecraft of large-angle attitude maneuver is investigated, and a control program based on the combination of adaptive robust control (ARC) and component synthesis vibration suppression method-seven-section path planning (CSVS-SPP) is proposed. The large-angle attitude maneuver route of the spacecraft, which serves as the reference path, is planned using the CSVS-SPP approach, and the attitude controller is designed using the ARC. This program can effectively reduce the influence of external disturbance and parameter uncertainty on the system performance while completing attitude maneuver and suppress the vibration of the flexible beam during large-angle attitude maneuver. The numerical simulations show the superiority and effectiveness of the proposed ARC+CSVS-SPP.
The Galerkin Method for Solving Strongly Nonlinear Oscillators
Authors: Salas Alvaro H. S.
Published: September 2022

In this paper, we make use of the Galerkin method for solving nonlinear second-order ODEs that are related to some strongly nonlinear oscillators arising in physics and engineering. We derive the iterative schemes for finding the coefficients that appear in the linear Galerkin hat combination in the ansatz form solution. These coefficients may be found iteratively by solving either a quadratic or a higher degree algebraic equation. Examples are presented to illustrate the obtained results. Some exact solutions are given, and they are compared with both the Runge–Kutta numerical solution and the solution obtained using the Galerkin finite element method.

Authors: Qiu Yao , Liu Yajie , Tong Ying , Xiang Xuyu
Published: September 2022

To solve the problems of cold start, sparse data, and poor recommendation performance in collaborative filtering recommendation, an end-to-end framework algorithm based on BiLSTM and BAGCN was proposed. In order to discover the higher-order structural information in the knowledge graph, stacked BiLSTM is used to extract the features of embedded entities and relationships, respectively, and the depth dependence features of user-item interaction matrix are mined. The neighborhood representation of each entity is then calculated by sampling adjacent entities of a fixed size. Then, the self-attention mechanism is used to learn the semantic association between entities and neighboring entities to obtain the final neighborhood information. Aggregators are used to combine neighborhood information and bias information when computing node representations. By extending the sampling of adjacent entities to multihop simulation of higher-order adjacent information, users’ potential long-distance interests can be captured. Compared with the baseline model, the superiority of this method is verified.

Authors: Yao Sheng
Published: September 2022

Appropriate business models are very important for enterprises. With the advent of the new century, the rapid development and application of technologies such as the Internet of Things and big data have become more and more widely used, which provides great convenience for people’s daily life. With the rise and development of the Internet of Things and big data technology, human work and life have become easier and easier, and it has also greatly changed human production and development. Under the fierce market competition, enterprises pay more and more attention to the independent research and development capabilities of their own brand products. With the rapid development of the Internet age, the status of brands in the improvement of business models is also increasing. The brand business model design must not only meet the ever-changing market consumer demand but also conform to the ever-changing fashion trends. The article briefly analyzed the development and application of the Internet of Things and big data technology and optimized the design method of the brand business model by using big data technology in design of the brand business model. On this basis, a decision support method for a brand business model based on a data warehouse was proposed to achieve scientific, efficient, and accurate brand product development. In order to understand consumers’ consumption habits and awareness of brands, the article randomly selected 400 people to conduct a survey. It was found that 45% of male respondents preferred commercials with simple and elegant colors; 38% of female respondents preferred commercials with minimalist styles. Modern consumers are mainly pragmatic, and the design of brand business models should be developed in this regard.

Introduction: Helicobacter pylori eradication is expected to significantly change the prevalence of Barrett’s esophagus (BE). However, few reports on this relationship exist. We analyzed the risk factors of BE using the current consensus on length of BE considering H. pylori infection status. Methods: We analyzed 10,122 individuals (5,962 men; mean age = 52.9 ± 9.9 years) who had undergone esophagogastroduodenoscopy as part of a medical checkup. Correlations among factors including H. pylori infectious status, endoscopic findings, and BE ≥1 cm were analyzed. Results: Prevalence of BE, long-segment BE, and esophageal adenocarcinoma was 22.5%, 0.014%, and 0%, respectively. Logistic regression analysis showed that the risk factors for BE were hiatal hernia (odds ratio [OR]: 2.89 [2.59–3.24]), female sex (OR: 0.52 [0.46–0.59]), social drinking (OR:0.77 [0.68–0.87]), H. pylori eradication therapy (OR: 1.34 [1.19–1.51]), proton pump inhibitor (PPI) use (OR: 1.52 [1.18–1.96]), bile reflux (OR: 1.18 [1.04–1.33]), age ≥50 years (OR: 1.13 [1.02–1.26]), and nonsteroidal anti-inflammatory drug (NSAID) use (OR: 1.29 [1.02–1.62]). Although reflux esophagitis (RE) was more common in H. pylori-negative patients (17.2%) than in those after H. pylori eradication therapy (11.8%, p < 0.00001), the latter was correlated with BE, disputing RE as a strong risk factor for BE. Therefore, we conducted a subgroup analysis; most of the risk factors except for PPI use (p = 0.75), H2-receptor antagonist use (p = 0.078), and atrophic gastritis absence (p = 0.72) were positively correlated with BE after H. pylori eradication therapy compared with H. pylori-negative status. Conclusions: H. pylori eradication, bile reflux, PPI use, and NSAID use were risk factors for BE along with hiatal hernia, male sex, and older age.
As circunstâncias da Independência e a formação do poder do atraso
Authors: Martins José de Souza
Published: September 2022

Para o autor, do ponto de vista sociológico, a história, como disciplina, é muito mais do que descrição e narrativa. É sobretudo uma busca das determinações sociais que explicam também o fazer história. E as efemérides, nessa perspectiva, deveriam ser momentos de construção da consciência crítica dos desencontros entre o que conseguimos ser e o que não conseguimos ser. O Bicentenário da Independência, portanto, pode ser um momento de rever concepções por meio das quais temos pensado e interpretado o Brasil.
Outros modernismos – uma questão de mérito, não de ritmo
Authors: Fischer Luís Augusto
Published: September 2022

O ensaio recupera os laços entre arte e contexto econômico e político de São Paulo na Primeira República, mostrando uma sinergia única entre elites sociais e vanguarda artística, em combate ao soft power carioca. Essa sinergia em seguida cresce pelo trabalho crítico consagrador dos valores modernistas pela intelectualidade da USP. Analisa o caráter da vanguarda enquanto tal, sua celebração da ruptura como ideal, e comenta o fato de que a vanguarda modernista paulista alcançou o poder em poucos anos, vindo a impor uma leitura exclusiva das coisas literárias e culturais. Conclui postulando que os muitos modernismos no Brasil só serão visíveis se a lente exclusivista do Modernismo paulista for devidamente posta em questão.
A questão nacional no Centenário da Independência: uma nação em busca da modernidade
Authors: Motta Marly
Published: September 2022

A proposta do artigo é analisar a mobilização da intelectualidade brasileira no intuito de construir um Brasil moderno por ocasião da celebração dos cem anos da Independência (1922). Marcada pela missão de “fecundar ideias singulares”, nem por isso a “geração de 22” se furtou a buscar a modernidade através de uma integração crítica e seletiva das ideias que então circulavam na Europa. Essa integração desemboca em duas correntes de pensamento – a tradição e a vanguarda –, que disputam o papel de porta-vozes exclusivos do que deveria ser o Brasil moderno. Como resultado dessa busca por um “novo” país, examinamos o projeto intelectual que visou à desqualificação do Rio de Janeiro como “cabeça da nação”, e sua substituição por São Paulo, lócus de produção de uma nova identidade nacional.

Published: September 2022

Background:

Mitral annular disjunction (MAD) has recently been recognized as an arrhythmogenic entity. Data on the electrophysiological substrate as well as the outcomes of catheter ablation of ventricular arrhythmias in patients with MAD is limited.

Methods:

Forty patients with MAD (mean age 47±15 years; 70% female) underwent catheter ablation for ventricular arrhythmias. Detailed clinical, electrocardiographic, cardiac imaging, and procedural data were collected. Clinical outcomes were compared between patients who had substrate modification in the MAD area and those who did not.

Results:

Twenty-three (57.5%) patients had ablation for premature ventricular contractions, 10 (25%) patients for sustained ventricular tachycardia, and 7 (17.5%) patients for premature ventricular contraction-triggered ventricular fibrillation. Mean end-systolic MAD length was 10.58±3.49 mm on transthoracic echocardiography. Seventeen (42.5%) patients had preprocedural cardiac magnetic resonance imaging, and 5 (29%) patients had late gadolinium enhancement. Among the 18 (45%) patients who had abnormal local electrograms (low voltage, long-duration, fractionated, isolated mid-diastolic potentials) during electroanatomical mapping, 10 (25%) patients had abnormal electrograms in the anterolateral mitral annulus and/or MAD area. Substrate modification was performed in 10 (25%) patients. Catheter ablation was acutely successful in 36 (90%) patients (elimination of premature ventricular contraction or noninducibility of ventricular tachycardia). After a median follow-up duration of 54.08 (interquartile range, 10.67–89.79) months, premature ventricular contraction burden decreased from a median of 9.75% (interquartile range, 3.25–14) before the ablation to a median of 4% (interquartile range, 1–7.75) after the ablation (
P
=0.03 [95% CI, 0.055–6.5]). Eight (20.5%) patients had repeat ablation for ventricular arrhythmias. Substrate modification of the MAD was associated with a trend toward lower rates of repeat ablation (0% versus 26.7%;
P
=0.16).

Conclusions:

Patients with MAD have a complex arrhythmogenic substrate, and catheter ablation is effective in reducing recurrence of ventricular arrhythmias. Substrate mapping and ablation may be considered in these patients.

Published: September 2022

Background:

Our understanding of catheter-based pulsed field ablation (PFA) of the ventricular myocardium is limited. We conducted a series of exploratory evaluations of ventricular PFA in swine ventricles.

Methods:

A focal lattice-tip catheter was used to deliver proprietary biphasic monopolar PFA applications to swine ventricles under general anesthesia, with guidance from electroanatomical mapping, fluoroscopy, and intracardiac echocardiography. We conducted experiments to assess the impact of (1) delivery repetition (2×, 3×, or 4×) at each location, (2) epicardial PFA delivery, and (3) confluent areas of shallow healed endocardial scar created by prior PFA (4 weeks earlier) on subsequent endocardial PFA. Additional assessments included PFA optimized for the ventricle, lesion visualization by intracardiac echocardiography imaging, and immunohistochemical insights.

Results:

Experiment no. 1: lesions (n=49) were larger with delivery repetition of either 4× or 3× versus 2×: length 17.6±3.9 or 14.2±2.0 versus 12.7±2.0 mm (
P
<0.01,
P
=0.22), width 13.4±1.8 or 10.6±1.3 versus 10.5±1.1 mm (
P
<0.01,
P
=1.00), and depth 6.1±2.1 or 5.1±1.3 versus 4.2±1.0 mm (
P
<0.01,
P
=0.21). Experiment no. 2: epicardial lesions (n=18) were reliably created and comparable to endocardial lesions: length 24.6±9.7 mm (n=5), width 15.6±4.6 mm, and depth 4.5±3.7 mm. Experiment no. 3: PFA (n=16) was able to penetrate to a depth of 4.8 (interquartile range, 4.5–5.4) mm in healthy myocardium versus 5.6 (interquartile range, 3.6–6.6) mm in adjacent healed endocardial scar (
P
=0.79), suggesting that superficial scar does not significantly impair PFA. Finally, we demonstrate, PFA optimized for the ventricle yielded adequate lesion dimensions, can result in myocardial activation, can be visualized by intracardiac echocardiography, and have unique immunohistochemical characteristics.

Conclusions:

This in vivo evaluation offers insights into the behavior of endocardial or epicardial PFA delivered using the lattice-tip catheter to normal or scarred porcine ventricular myocardium, thereby setting the stage for future clinical studies.
Racial Disparity in Referral for Catheter Ablation for Atrial Fibrillation at a Single Integrated Health System
Authors: Duke Jessica M. , Muhammad Lutfiyya N. , Song Jing , Tanaka Yoshihiro , Witting Celeste , Khan Sadiya S. , Passman Rod S.
Published: September 2022

Background

Guidelines recommend catheter ablation of atrial fibrillation (AFCA) as an option for rhythm control. Studies have shown that Black patients are less likely to undergo AFCA compared with White patients. We investigated whether differences in referral patterns play a role in this observed disparity.

Methods and Results

Using an integrated repository from the electronic medical record at Northwestern Medicine, we conducted a retrospective cohort study of outpatients with newly diagnosed atrial fibrillation. Baseline characteristics by race and ethnicity were compared. Logistic regression models adjusted for socioeconomic and health factors were constructed to determine the association between race and ethnicity and binary dependent variables including referrals and visits to general cardiology and cardiac electrophysiology (EP) and AFCA. Of 5445 patients analyzed, 4652 were non‐Hispanic White (NHW) and 793 were non‐Hispanic Black (NHB). In adjusted models, NHB patients initially diagnosed with atrial fibrillation in internal medicine and primary care had a significantly greater odds of referral to general cardiology; among all patients in the cohort, there was no significant difference in the odds of referral to EP between NHB and NHW patients; and there were no differences in the odds of completing a visit in general cardiology or EP. Among patients completing an EP visit, NHB patients were less likely to undergo AFCA (odds ratio, 0.63 [95% CI, 0.40–0.98],
P
=0.040).

Conclusions

Similar referral rates to general cardiology and EP were observed between NHB and NHW patients. Despite this, NHB patients were less likely to undergo AFCA.
Eligibility for Posthospitalization Venous Thromboembolism Prophylaxis in Hospitalized Patients With COVID‐19: A Retrospective Cohort Study
Authors: Vaughn Valerie M. , Ratz David , McLaughlin Elizabeth S. , Horowitz Jennifer K. , Flanders Scott A. , Middleton Elizabeth A. , Grant Paul J. , Kaatz Scott , Barnes Geoffrey D.
Published: September 2022

Background

A recent randomized trial, the MICHELLE trial, demonstrated improved posthospital outcomes with a 35‐day course of prophylactic rivaroxaban for patients hospitalized with COVID‐19 at high risk of venous thromboembolism. We explored how often these findings may apply to an unselected clinical population of patients hospitalized with COVID‐19.

Methods and Results

Using a 35‐hospital retrospective cohort of patients hospitalized between March 7, 2020, and January 23, 2021, with COVID‐19 (MI‐COVID19 database), we quantified the percentage of hospitalized patients with COVID‐19 who would be eligible for rivaroxaban at discharge per MICHELLE trial criteria and report clinical event rates. The main clinical outcome was derived from the MICHELLE trial and included a composite of symptomatic venous thromboembolism, pulmonary embolus‐related death, nonhemorrhagic stroke, and cardiovascular death at 35 days. Multiple sensitivity analyses tested different eligibility and exclusion criteria definitions to determine the effect on eligibility for postdischarge anticoagulation prophylaxis. Of 2016 patients hospitalized with COVID‐19 who survived to discharge and did not have another indication for anticoagulation, 25.9% (n=523) would be eligible for postdischarge thromboprophylaxis per the MICHELLE trial criteria (range, 2.9%–39.4% on sensitivity analysis). Of the 416 who had discharge anticoagulant data collected, only 13.2% (55/416) were actually prescribed a new anticoagulant at discharge. Of patients eligible for rivaroxaban per the MICHELLE trial, the composite clinical outcome occurred in 1.2% (6/519); similar outcome rates were 5.7% and 0.63% in the MICHELLE trial's control (no anticoagulation) and intervention (rivaroxaban) groups, respectively. Symptomatic venous thromboembolism events and all‐cause mortality were 6.2% (32/519) and 5.66% in the MI‐COVID19 and MICHELLE trial control cohorts, respectively.

Conclusions

Across 35 hospitals in Michigan, ≈1 in 4 patients hospitalized with COVID‐19 would qualify for posthospital thromboprophylaxis. With only 13% of patients actually receiving postdischarge prophylaxis, there is a potential opportunity for improvement in care.
Theory, Philosophy, Film Studies, and Science: A Response to D. N. Rodowick's Philosophy's Artful Conversation and Murray Smith's Film, Art and the Third Culture
Authors: Turvey Malcolm
Published: September 2022

Two film theorists, D. N. Rodowick and Murray Smith, have recently addressed the place of the natural sciences in the study of film and art, and they reach diametrically opposed conclusions. Rodowick argues that natural-scientific explanations have little or no role to play in the study of film and art as “cultural practices,” while Smith advocates a “naturalized aesthetics of film,” which he describes as “an approach that … treats [film] as a phenomenon which is likely to be illuminated by various types of scientific as well as traditional humanistic research.”

In this paper, I argue that, while both views contain important insights, they are ultimately mistaken. Rodowick overlooks the important role the natural sciences can play in explaining the perceptual, cognitive, affective, and bodily capacities that shape and constrain our engagement with art as well as the properties of artworks that elicit and inform this engagement. Nevertheless, this does not mean, I maintain, that aesthetics should be naturalized, as Smith believes, given that the types of explanations standardly proffered in film studies and other humanistic disciplines can be autonomous from those of the natural sciences in the sense of being explanatorily self-sufficient.
Zoonotic Undemocracy
Authors: Gerspacher Arnaud
Published: September 2022

On a surreal day in August 2019, smoke clouds rising from the burning Amazon plunged Sa?o Paulo into darkness. Pasture-clearing cattle industries in Brazil, largely responsible for these fires, soon became a matter of global concern. A different sort of crisis took hold half year later—the COVID-19 pandemic, which likely originated in a bat. These two events, though seemingly disconnected, involve consuming animal bodies in ways that have compromised planetary habitability—one through deforestation and greenhouse gases, the other through confinement and a novel coronavirus. This essay argues for the urgency of re-thinking politics from a posthumanist perspective, one that considers the impact of environmental harm caused by the uses of nonhuman animals. Democracy is shaped by such eco-political realities, as demonstrated in the multi-species authoritarianism of Brazilian president Jair Bolsonaro's “bancadas de bi?blia, bo?i, e bala” (“senate seats filled with bibles, beef, and bullets”).

This essay focuses on Wilson Coutinho's experimental short film Cildo Meireles (1979) as well Meireles art installations that incorporate nonhuman animals. Coutinho and Meireles were prescient in their attention to the role of nonhuman animals within the histories of colonialism/neocolonialism and the immiseration of indigenous communities at the hands of such undemocratic forces as corrupt politicians and ranchers. Their work offers a multi-species analysis of global warming, biodiversity loss, racist food politics, and the incubation of zoonotic illnesses—all of which have led to a withering of democracy within Brazil's borders and beyond.
On Bolivia: A Debt to Beauty
Authors: Cruz Max Jorge Hinderer
Published: September 2022

After the coup d’état in Bolivia, in November 2019, a presidential decree was passed that potentially criminalized journalists, bloggers, and artists by holding that to the extent their work could be characterized as confusing public opinion it would be considered to constitute a danger to public health. The present text “A Debt to Beauty” offers a brief analysis of the historical relationship between silence and beauty, as well as the ethical dimension of the act of contemplating beauty in a museum—the debt one incurs, as it were, to beauty.
How to Dissect a Muppet: The Structure of Transformer Embedding Spaces
Authors: Mickus Timothee , Paperno Denis , Constant Mathieu
Published: September 2022

Pretrained embeddings based on the Transformer architecture have taken the NLP community by storm. We show that they can mathematically be reframed as a sum of vector factors and showcase how to use this reframing to study the impact of each component. We provide evidence that multi-head attentions and feed-forwards are not equally useful in all downstream applications, as well as a quantitative overview of the effects of finetuning on the overall embedding space. This approach allows us to draw connections to a wide range of previous studies, from vector space anisotropy to attention weights.

Published: September 2022

The Faculty of Public Governance and International Studies of Ludovika – University of Public Service Budapest (UPS) hosted the first Global Conference on Parliamentary Studies in cooperation with the International Journal of Parliamentary Studies on 12-13 May 2022. The conference aimed to break down the clear barriers between political science and law, science and practice, national and international approaches. More than 40 papers by speakers from 15 countries and 4 continents were presented. This included parliaments in the global south and in hybrid regimes. In this article we briefly summarises the main takeaway messages from the conference.
Paul Knitter’s Theology of Religions: A Survey and Evangelical Response
Authors: Eddy Paul R.
Published: September 2022

Paul Knitter has become a figurehead of the increasingly popular theology of religions known as religious pluralism. The first half of this study traces Knitter’s theological journey to and through the pluralist paradigm. Focus will be given to Knitter’s current soteriocentric model. The last half of the article comprises an evangelical response, first, to the general foundations of pluralism, and second, to the central aspects of Knitter’s soteriocentric approach to interreligious relationships and dialogue. Specifically, Knitter’s ideas are be evaluated by submitting them to the two criteriological touchstones which he himself acknowledges: ‛Does it work’ (i.e., does his position actually foster authentic dialogue)?, and ‛Is it Christian’?
The Need and Promise of Christian Preaching
Authors: Rees Frank D.
Published: September 2022

This article takes its title from a 1922 lecture by Karl Barth and explores the contemporary relevance of some of Barth’s ideas towards a re-affirmation of the nature and importance of preaching within the church. Fundamental to preaching is the potential of such communication to change relationships, but this in turn requires a dialectic involving a questioning congregation and a theological articulation of the questions of the day. This aspect of Barth's thinking expresses his understanding of worship as the goal of preaching, derived from Kierkegaard's idea of contemporaneity. The theological foundations of such communication require that we see preaching as a work of the Holy Spirit and thus as a sacrament of the divine presence, with preacher and congregation as sacramentals.
Authentein once More: A Response to L. E. Wilshire
Authors: Barnett Paul W.
Published: September 2022

The author explains why he understood L. E. Wilshire’s interpretation of authentein as a word used in connection with ‘murder ... crime’ or ‘authority’, notes that in a later paper Wilshire dropped the second of these possibilities in relation to 1 Tim. 2:12, and briefly criticises his hypothesis that church women in Ephesus were reacting violently against false teachers who were repudiating marriage and child-bearing.
The Evangelical Succession? Evangelical History and Denominational Identity
Authors: Brown Ralph
Published: September 2022

This article analyses changing Evangelical conceptions of history and their role in the developing denominational identity of Evangelicalism. It is argued that the concept of an Evangelical Succession was a response to the particular religious and cultural climate of the mid-nineteenth century. It grew out of a new form of providentialist history and provided the theological justification for an Evangelical commitment to the preservation of a narrowly conceived form of national Protestantism. It is also argued that the historical legitimation of Evangelical Anglicanism was an essential element in Evangelical responses to the development of the Evangelical Alliance. The article then concludes with a discussion of the implications of different interpretations of denominational identity for the maintenance of Evangelical unity.
‛On That Night’: Luke 17:34
Authors: Derrett J. Duncan M.
Published: September 2022

Salvation, present for Matthew (24:40b,41b), is future for Luke, who may have discarded the image of the two men in the field, and substituted the two in the bed. As at the Redemption from Egypt almost all Israelites were made into companies by Yahweh and led (with a strong arm) out of Egypt, whereas their Egyptian comrades were left behind, so the critical moment on the path to the Promised Land, coinciding with the coming of the Son of man, will find people of apparently like circumstances divided into the saved and the damned. There is no more time for probation and amelioration than there was at the first Exodus, for all necessary warnings have been issued to him/her who, willy nilly, consorts with the ‛world’ (Lk. 12:30). The Redemption from Egypt not only created a special obligation of obedience towards God and love towards the ‛neighbour’, but also excluded the idea, encouraged by appearances, that those who share the life of this world will share in the next. Luke’s ‛on that night’ ensures that we refer to the Exodus, which is a suggestive way of describing Jesus’ activity as leader (Ps. 78:52). Nevertheless mere membership of a group will not avail (cf. Mt. 23:9-10,27-29), since redemption is an individual affair. Slaves of sin, lacking faith in the redeemer, will not be ransomed at the final Exodus.
Evangelical Inclusivism: Progress or Betrayal?
Authors: Gillis Chester
Published: September 2022

Controversial voices have arisen from within the ranks of evangelical theologians challenging the hegemony that an exclusivist soteriology has enjoyed to date. In particular, the work of Clark Pinnock and John Sanders has broken new ground among evangelical theologians by suggesting that inclusivism is a reasonable and justified theological position. This work presents new options for intra-Christian dialogue in which evangelical theology is no longer excluded, rejected or marginalized outright by the dominant proponents of inclusivism or the liberal (radical) voices advocating pluralism. This selective reformulation of evangelical soteriology in the light of contemporary religious plurality is significant not only for those within evangelicalism who subscribe to it, but equally important for non-evangelical Christian theologians who attempt to construct Christian soteriologies, often without any reference to evangelical theology. This article assesses critically the benefits and drawbacks of this move to inclusivism in terms of the larger project of interreligious interchange.
The Johannine Prologue—a Microcosm of the Gospel
Authors: Ross Valentine Simon
Published: September 2022

The aim of this article has been to provide an appraisal of the nature of the Johannine Prologue. It is the writer’s belief that the first eighteen verses of the Fourth Gospel were not only a part of the original gospel, but that they provide the exegetical key to the right understanding of the entire book. Accordingly it is suggested that the Prologue is a summation of John’s theological stance, containing in embryonic form, the main themes, which gradually unfold and develop in the following chapters. The Prologue is therefore a microcosm of the gospel which adumbrates and anticipates the Johannine presentation of God’s salvific scheme, the incarnation of the Son and the redemption of the world, providing eternal life for all those who believe.
Three Brazilian species of Begonia (Begoniaceae) from the state of Rio de Janeiro, Brazil
Authors: JACQUES ELIANE DE LIMA
Published: September 2022

Begonia altimontana, B. inumbrata and B. pedrabrancencis (Begoniaceae) are species endemic to the Brazilian Atlantic Coastal Forest, an area rich in endemism and species diversity, and are described and illustrated herein. Begonia altimontana resembles B. olsoniae L.B.Sm. & B.G.Schub., B. princeps A.DC. and B. ramentacea Paxton in the shape of leaf blades and squamulose petioles, and is found in the same habit (rocky slopes and outcrops). Begonia inumbrata resembles B. fluminensis Brade in the shape of the leaf blades and fruit, and B. pedrabrancencis is morphological similar to B. bidentata Raddi sharing the same shape of the leaf blades and venation. We place both new species in Begonia sect. Pritzelia, based on their similarity to other species in the section, however this section is highly polymorphic, and we highlight that further work is needed on sectional placement. The lectotype of Begonia bidentata Raddi is designated here and we also lectotypified B. ramentacea Paxton using an illustration and designated an epitype.
