Fusion of medical images using Nabla operator; Objective evaluations and step-by-step statistical comparisons
Authors: Behrouzi Yasin , Basiri Abdolali , Pourgholi Reza , Kiaei Ali Akbar
Published: August 2023

Since vectors include direction and magnitude, they have more information than scalars. So, converting the scalar images into the vector field leads achieving much information about the images that have been hidden in the spatial domain. In this paper, the proposed method fuses images after transforming the scalar field of images to a vector one. To transform the field, it uses Nabla operator. After that, the inverse transform is implemented to reconstruct the fused medical image. To show the performance of the proposed method and to evaluate it, different experiments and statistical comparisons were accomplished. Comparing the experimental results with the previous works, shows the effectiveness of the proposed method.

Drug repurposing is the finding new activity of the existing drug. Recently, Albendazole’s well-known antihelmintic has got the attention of an anticancer drug. Plausible evidence of the interaction of Albendazole with one of the types of tyrosine kinase protein receptor, vascular endothelial growth factor receptor-2 (VEGFR-2) is still not well understood. Inhibition of the VEGFR-2 receptor can prevent tumor growth. The current study investigated the interaction of Albendazole with VEGFR-2.It was found that the said interaction exhibited potent binding energy ΔG = -7.12 kcal/mol, inhibitory concentration (Ki) = 6.04 μM, and as positive control comparison with standard drug (42Q1170A) showed ΔG = -12.35 kcal/mol and Ki = 881 μM. The key residue Asp1046 was formed involved hydrogen bonding with Albendazole. The molecular dynamics simulation study revealed the stable trajectory of the VEGFR-2 receptor with Albendazole bound complex having significant high free energy of binding as calculated from Molecular Mechanics Generalized Born and Surface Area study ΔG = -42.07±2.4 kcal/mol. The binding energy is significantly high for greater stability of the complex. Principal component analysis of molecular docking trajectories exhibited ordered motion at higher modes, implying a high degree of VEGFR-2 and Albendazole complex stability as seen with the standard drug 42Q. Therefore, the current work suggests the role of Albendazole as a potent angiogenesis inhibitor as ascertained by its potential interaction with VEGFR-2. The findings of research will aid in the future development of Albendazole in anticancer therapy.
Empirical distributions of time intervals between COVID-19 cases and more severe outcomes in Scotland
Authors: Wood Anthony J. , Kao Rowland R.
Published: August 2023

A critical factor in infectious disease control is the risk of an outbreak overwhelming local healthcare capacity. The overall demand on healthcare services will depend on disease severity, but the precise timing and size of peak demand also depends on the timeinterval(or clinical time delay) between initial infection, and development of severe disease. A broaderdistributionof intervals may draw that demand out over a longer period, but have a lower peak demand. These interval distributions are therefore important in modelling trajectories of e.g. hospital admissions, given a trajectory of incidence. Conversely, as testing rates decline, an incidence trajectory may need to be inferred through the delayed, but relatively unbiased signal of hospital admissions. Healthcare demand has been extensively modelled during the COVID-19 pandemic, where localised waves of infection have imposed severe stresses on healthcare services. While the initial acute threat posed by this disease has since subsided with immunity buildup from vaccination and prior infection, prevalence remains high and waning immunity may lead to substantial pressures for years to come. In this work, then, we present a set of interval distributions, for COVID-19 cases and subsequent severe outcomes; hospital admission, ICU admission, and death. These may be used to model more realistic scenarios of hospital admissions and occupancy, given a trajectory of infections or cases. We present a method for obtaining empirical distributions using COVID-19 outcomes data from Scotland between September 2020 and January 2022 (N= 31724 hospital admissions,N= 3514 ICU admissions,N= 8306 mortalities). We present separate distributions for individual age, sex, and deprivation of residing community. While the risk of severe disease following COVID-19 infection is substantially higher for the elderly and those residing in areas of high deprivation, the length of stay shows no strong dependence, suggesting that severe outcomes are equally severe across risk groups. As Scotland and other countries move into a phase where testing is no longer abundant, these intervals may be of use for retrospective modelling of patterns of infection, given data on severe outcomes.

The identification of factors impeding normal fetal development and growth is crucial for improving neonatal health. Historical studies are relevant because they show which parameters have influenced neonatal health in the past in order to better understand the present. We studied temporal changes of neonatal health outcomes (birth weight, gestational age, stillbirth rate) and the influence of different cofactors in two time periods. Moreover, we investigated particularly neonatal health in the wake of the 1918/19 influenza pandemic. Data were transcribed from the Bern Maternity Hospital and consists of two time periods: A) The years 1880, 1885, 1890, 1895 and 1900 (N = 1530, births’ coverage 20%); B) The years 1914–1922 (N = 6924, births’ coverage 40–50%). Linear regression models were used to estimate the effect of birth year on birth weight, and logistic regression models to estimate the effect of birth year and of the exposure to the pandemic on premature birth, stillborn and low birth weight (LBW). Mean birth weight increased only minimally between the two datasets; whereas, in the years 1914–1922, the preterm birth and stillbirth rates were markedly reduced compared with the years 1880–1900. Sex, parity, gestational age and maternal age were significantly associated with birth weight in both time periods. The probability of LBW was significantly increased in 1918 (OR 1.49 (95% CI 1.00–2.23)) and in 1919 (OR 1.55 (95% CI 1.02–2.36)) compared to 1914. Mothers who were heavily exposed to the influenza pandemic during pregnancy had a higher risk of stillbirth (OR 2.27 (95% CI 1.32–3.9)). This study demonstrated that factors influencing neonatal health are multifactorial but similar in both time periods. Moreover, the exposure to the 1918/19 pandemic was less associated with LBW and more associated with an increased risk of stillbirth. If this trend is confirmed by further studies, it could indicate some consistency across pandemics, as similar patterns have recently been shown for COVID-19.

Published: August 2023

Despite millions of dogs entering and exiting shelters annually, little is known about dog behavior long-term after adoption. Entering a shelter is stressful for dogs which may inhibit or exaggerate behavior. There is a common public sentiment that dogs have a “honeymoon period” after adoption where dogs do not show their full repertoire of behaviors, both positive and negative, until getting more comfortable in their new home. The aim of this prospective observational cohort study was to identify prevalence of and changes in behavior issues in dogs throughout the first six months following adoption. The owners of ninety-nine dogs adopted from five Ohio shelters between October 1, 2020 and June 1, 2021 were surveyed 7, 30, 90, and 180 days after adoption, using the Canine Behavioral Assessment & Research Questionnaire (C-BARQ). Owners were also asked about household changes that may affect behavior. Estimated age, sex, weight, length of shelter stay, shelter intake reason, use of gastrointestinal, antibiotic, and psychotropic medications in the shelter, whether the animal had been previously returned to the shelter, and whether the owner was a first-time dog owner, were evaluated as predictors in a mixed effect regression model of different behavior measures over time. At various timepoints, dogs showed high prevalence for stranger-directed aggression (81.7%), owner-directed aggression (32.3%), dog-directed aggression (75%), familiar dog aggression (37.8%), stranger directed fear (58.2%), nonsocial fear (95.8%), dog directed fear (80.0%) and separation-related behaviors (92.6%). Over 180 days, stranger-directed aggression, excitability, touch sensitivity, training difficulty, and chasing increased, while separation-related behaviors, attachment and attention-seeking decreased. Owners reported high satisfaction with their dogs’ behavior. Use of psychotropic medications in the shelter was predictive of stranger-directed aggression and touch sensitivity at home. These findings help veterinarians and shelter professionals council owners on potential behavior changes after adoption.
Link prediction on bipartite networks using matrix factorization with negative sample selection
Authors: Peng Siqi , Yamamoto Akihiro , Ito Kimihito
Published: August 2023

We propose a new method for bipartite link prediction using matrix factorization with negative sample selection. Bipartite link prediction is a problem that aims to predict the missing links or relations in a bipartite network. One of the most popular solutions to the problem is via matrix factorization (MF), which performs well but requires reliable information on both absent and present network links as training samples. This, however, is sometimes unavailable since there is no ground truth for absent links. To solve the problem, we propose a technique called negative sample selection, which selects reliable negative training samples using formal concept analysis (FCA) of a given bipartite network in advance of the preceding MF process. We conduct experiments on two hypothetical application scenarios to prove that our joint method outperforms the raw MF-based link prediction method as well as all other previously-proposed unsupervised link prediction methods.
Using the health belief model to understand the factors influencing the perceptions of people of Chinese ancestry about reducing salt consumption for hypertension prevention: A cross-sectional study
Authors: Chan Alex , Wai-chi Chan Sally , Kinsman Leigh
Published: August 2023

Background

High-salt diets are linked to hypertension. Chinese people in Australia, are at increased risk of hypertension due to the combination of routine addition of high quantities of salt to food during cooking and high salt levels in processed western foods. There is a scarcity of salt-related behavioural studies on this population group. This study aimed to explore the habitual salt consumption of Chinese Australians and factors that influence their perceptions about sustaining salt-related behavioural changes for hypertension prevention.

Method

A cross-sectional descriptive study using an adapted Determinants of Salt-Restriction Behaviour Questionnaire was conducted on 188 Chinese Australians. A non-probability sampling method was used to attract participants from different parts of Australia. Statistical analyses such as descriptive analysis, t-tests and Pearson correlation tests were performed in the study.

Results

Over 97% of participants did not measure the amount of salt added to their meals. Many participants reported that salt was added to their meals based on their experience (39.4%) and food taste (31.9%). Over 80% of participants did not know the recommended level of daily salt consumption. Although salt-related knowledge had no significant correlation with individuals’ salty food taste preferences, there were significant correlations with the perceptions of the severity of disease and health benefits of reducing salt consumption (p = .001 and < .001 respectively). People with stronger salty taste preferences perceived a higher level of health threat than people with lighter salty taste preferences (p = .003).

Conclusion

Findings from this study show that knowledge about salt-reduction alone had no significant effects on salt-related behaviours. Adequate culturally relevant practice-based education in salt-reduction strategies may facilitate salt-related behavioural changes in Chinese Australians. Overall, single young Chinese Australian men with stronger salty taste preferences is the group who needs salt reduction interventions the most.

Published: August 2023

Root-knot nematodes (Meloidogynespp.) are dangerous parasites of many crops worldwide. The threat of chemical nematicides has led to increasing interest in studying the inhibitory effects of organic amendments and bacteria on plant-parasitic nematodes, but their combination has been less studied. One laboratory and four glasshouse experiments were conducted to study the effect onM.javanicaof animal manure, common vermicompost, shrimp shells, chitosan, compost and vermicompost from castor bean, chinaberry and arugula, and the combination of arugula vermicompost with some bacteria, isolated from vermicompost or earthworms. The extract of arugula compost and vermicompost, common vermicompost and composts from castor bean and chinaberry reduced nematode egg hatch by 12–32% and caused 13–40% mortality of second-stage juveniles in vitro. Soil amendments with the combination vermicompost of arugula +Pseudomonas.resinovorans+Sphingobacterium daejeonense+ chitosan significantly increased the yield of infected tomato plants and reduced nematode reproduction factor by 63.1–76.6%. Comparison of chemical properties showed that arugula vermicompost had lower pH, EC, and C/N ratio than arugula compost. Metagenomics analysis showed thatBacillus,Geodermatophilus,Thermomonas,Lewinella,PseudolabrysandErythrobacterwere the major bacterial genera in the vermicompost of arugula. Metagenomics analysis confirmed the presence of chitinolytic, detoxifying and PGPR bacteria in the vermicompost of arugula. The combination of arugula vermicompost + chitosan +P.resinovorans+S.daejeonensecould be an environmentally friendly approach to controlM.javanica.
Membrane metalloendopeptidase (MME) is positively correlated with systemic lupus erythematosus and may inhibit the occurrence of breast cancer

Published: August 2023

Background

Patients with systemic lupus erythematosus (SLE) have a lower risk of breast cancer (BRCA) than the general population. In this study, we explored the underlying molecular mechanism that is dysregulated in both diseases.

Methods

Weighted gene coexpression network analysis (WGCNA) was executed with the SLE and BRCA datasets from the Gene Expression Omnibus (GEO) website and identified the potential role of membrane metalloendopeptidase (MME) in both diseases. Then, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses of related proteins and miRNAs were performed to investigate the potential molecular pathways.

Results

WGCNA revealed that MME was positively related to SLE but negatively related to BRCA. In BRCA, MME expression was significantly decreased in tumor tissues, especially in luminal B and infiltrating ductal carcinoma subtypes. Receiver operating characteristic (ROC) analysis identified MME as a valuable diagnostic biomarker of BRCA, with an area under the curve (AUC) value equal to 0.984 (95% confidence interval = 0.976–0.992). KEGG enrichment analysis suggested that MME-related proteins and targeted miRNAs may reduce the incidence of BRCA in SLE patients via the PI3K/AKT/FOXO signaling pathway. Low MME expression was associated with favorable relapse-free survival (RFS) but no other clinical outcomes and may contribute to resistance to chemotherapy in BRCA, with an AUC equal to 0.527 (P value < 0.05).

Conclusions

In summary, MME expression was significantly decreased in BRCA but positively correlated with SLE, and it might reduce the incidence of BRCA in SLE patients via the PI3K/AKT/FOXO signaling pathway.

Published: August 2023

Although recent technological developments in the field of bionic upper limb prostheses, their rejection rate remains excessively high. The reasons are diverse (e.g. lack of functionality, control complexity, and comfortability) and most of these are reported only through self-rated questionnaires. Indeed, there is no quantitative evaluation of the extent to which a novel prosthetic solution can effectively address users’ needs compared to other technologies. This manuscript discusses the challenges and limitations of current upper limb prosthetic devices and evaluates their functionality through a standard functional assessment, the Assessment of Capacity for Myoelectric Control (ACMC). To include a good representation of technologies, the authors collect information from participants in the Cybathlon Powered Arm Prostheses Race 2016 and 2020. The article analyzes 7 hour and 41 min of video footage to evaluate the performance of different prosthetic devices in various tasks inspired by activities of daily living (ADL). The results show that commercially-available rigid hands perform well in dexterous grasping, while body-powered solutions are more reliable and convenient for competitive environments. The article also highlights the importance of wrist design and control modality for successful execution of ADL. Moreover, we discuss the limitations of the evaluation methodology and suggest improvements for future assessments. With regard to future development, this work highlights the need for research in intuitive control of multiple degrees of freedom, adaptive solutions, and the integration of sensory feedback.
Subjective feeling of control during fNIRS-based neurofeedback targeting the DL-PFC is related to neural activation determined with short-channel correction

Published: August 2023

Neurofeedback (NF) training is a promising preventive and therapeutic approach for brain and behavioral impairments, the dorsolateral prefrontal cortex (DL-PFC) being a relevant region of interest. Functional near-infrared spectroscopy (NIRS) has recently been applied in NF training. However, this approach is highly sensitive to extra-cerebral vascularization, which could bias measurements of cortical activity. Here, we examined the feasibility of a NF training targeting the DL-PFC and its specificity by assessing the impact of physiological confounds on NF success via short-channel offline correction under different signal filtering conditions. We also explored whether the individual mental strategies affect the NF success. Thirty volunteers participated in a single 15-trial NF session in which they had to increase the oxy-hemoglobin (HbO2) level of their bilateral DL-PFC. We found that 0.01–0.09 Hz band-pass filtering was more suited than the 0.01–0.2 Hz band-pass filter to highlight brain activation restricted to the NF channels in the DL-PFC. Retaining the 10 out of 15 best trials, we found that 18 participants (60%) managed to control their DL-PFC. This number dropped to 13 (43%) with short-channel correction. Half of the participants reported a positive subjective feeling of control, and the “cheering” strategy appeared to be more effective in men (p<0.05). Our results showed successful DL-PFC fNIRS-NF in a single session and highlighted the value of accounting for extra cortical signals, which can profoundly affect the success and specificity of NF training.

Published: August 2023

Genetic engineering of animals has been proposed to address societal problems, but public acceptance of the use of this technology is unclear. Previous work has shown that the source of information proposing the technology (e.g. companies, universities), the term used to describe the technology (e.g. genome editing, genetic modification), and the genetic engineering application (e.g. different food products) affects technology acceptance. We conducted three mixed-method surveys and used a causal trust-acceptability model to understand social acceptance of genetic engineering (GE) by investigating 1) the source of information proposing the technology, 2) the term used to describe the technology, and 3) the GE application for farm animals proposed. Further, participants expressed their understanding of technology using a range of terms interchangeably, all describing technology used to change an organism’s DNA. We used structural equation modelling and confirmed model fit for each survey. In each survey, perceptions of benefit had the greatest effect on acceptance. Following our hypothesized model, social trust had an indirect influence on acceptance through similar effects of perceived benefit and perceived risk. Additional quantitative analysis showed that the source of information and technology term had little to no effect on acceptance. Applications involving animals were perceived as less beneficial than a plant application, and an application for increased cattle muscle growth was perceived as more risky than a plant application. When assessing the acceptability of applications participants considered impacts on plants, animals, and people, trust in actors and technologies, and weighed benefits and drawbacks of GE. Future work should consider how to best measure acceptability of GE for animals, consider contextual factors and consider the use of inductive frameworks.
Tracing the evolution of green logistics: A latent dirichlet allocation based topic modeling technology and roadmapping
Authors: Ma Ruijundi , Kim Yong Jin
Published: August 2023

Green logistics (GL) is the main development trend of modern logistics. The analysis of green logistics topics and their evolution is helpful in grasping its development trend and doing research facing the international frontier. Focusing on the hot topics and evolution process of green logistics, this paper analyzes from four aspects: firstly, this study divides the green logistics development progress into three stages based on life cycle theory, which are the emerging stage (1993–2003), slow growth stage (2004–2014) and rapid growth stage (2015–2021). Then, based on latent dirichlet allocation (LDA) topic model, this study summarizes and confirms related words and meaning of each topic in different stages. Furthermore, this study calculates the text similarity in each development stage of green logistics and analyzes the trend of hot topics in green logistics. Finally, this paper visualizes the development roadmap of green logistics and explores the progression among three stages. There are 4, 5, and 7 topics defined respectively in three development stages. The revolution of green logistics is analyzed, and the results show that "model and management on sustainable development of GL", "related issues and potential threats of GL", and "optimization analysis of low-carbon vehicle routing and time" are the primary development trends of green logistics. This study fills the gap in considering the evolution process of green logistics through topic modeling and roadmapping method. It provides a particular theoretical significance for the green and sustainable development of logistics.
On documentarity in theatre: Post-yu traumas
Authors: Bozovičar Rok
Published: August 2023

Let me begin with a brief counter-memory about the first performance I saw of those Zala Dobovšek reviews in her monograph (I saw Izdajalec (The Traitor) a bit later on). It must’ve been in spring 2011 in Belgrade. I was on a student excursion. I haven’t the faintest memory how I chanced upon the performance Rođeni u YU (Born in YU) or where I got the tickets, since I spent most of my days hanging in bookstores, which later on turned out to have a significant influence on my graduation thesis and further studies. But I do remember Radovan Vujović and Branka Petrić, even though the cast included the likes of Mirjana Karanović and Predrag Ejdus,1 and a spectacular applause on an open stage, which I’ve never witnessed before (or since, except in Serbia). About 22 years old, I was dismayed by the outspokenness and emotional charge of the performance, an unforgettable experience that left me profoundly rattled. In theatre, it’s something that happens to me approximately every three years.

The following thoughts are a journey through examples from some of my practices and positions that I inhabit most often as a dramaturge, while looking around my ecosystem that might otherwise be called the local context of Zagreb’s independent performing arts scene. I want to share several tentative claims that stem from my recent efforts in dealing with working conditions in culture, while also trying to derive methods for devised performancemaking from them. I’d like to think of this journey as bearing resemblances with the Babushka-like experience of waking up from a dream to yet another dream.
The emergence of cultural production

Educação e relações étnico-raciais: Instrumentos, Ferramentas – Intencionalidade e Propósito
Authors: De Almeida Rogério Salatini
Published: August 2023

Este artigo tem por objetivo apresentar uma reflexão em tópicos, com abordagem de viés filosófico, que aponta na direção de entender as práticas antirracistas como desdobramentos de elementos maiores nas relações de ensino-aprendizagem: a intencionalidade antirracista e o propósito antirracista. Estes conceitos são atrelados ao “método de cartografias” apresentado sob a ótica da artista educadora Sumaya Mattar, para que se defenda que sejam desvelados pelo modo como propõe a autora. E por fim rascunha uma proposta de diferenciação entre as ideias de ‘combate’ e ‘resistência’, que podem ser entendidas no termo “antirracista”, afirmando que a segunda, tendo por base o pensamento de Gilles Deleuze, é uma forma em devir de prática antirracista, e por isso dotada de uma potência de ato criador.

Published: August 2023

Este estudo, de abordagem qualitativa, analisou concepções de fracasso escolar e proposições práticas para o seu enfrentamento, presentes em trabalhos acadêmicos da área da Educação. A investigação utilizou-se da pesquisabibliográfica, desenvolvida por meio do levantamento de dissertações e teses produzidas no Brasil no período de 2015 a 2020 que tinham como tema central o fracasso escolar. Para tal, foi tomado como fonte um dos principais portais acadêmicos do país, a Biblioteca Digital Brasileira de Teses e Dissertações (BDTD), coordenada pelo Instituto Brasileiro de Informação em Ciência e Tecnologia (IBICT). O referencial teórico contou com os aportes de Maria H. Patto (1999), Paulo Freire (1987) e Pierre Bourdieu (1992). O estudo permitiu concluir que, na atualidade, o fracasso escolar tende a ser discutido, em nível da teoria, a partir de uma visão mais ampla, que busca contextualizar e evidenciar os múltiplos fatores de sua produção. Isso parece indicar um avanço, uma vez que supera concepções anteriores fragmentadas e focalistas. Os achados reafirmam a necessidade de buscar alternativas teórico-práticas que potencializem a garantia do direito ao acesso e permanência à uma educação com qualidade social.

Usaha tambak udang merupakan usaha yang sangat menjanjikan saat ini. Masyarakat di Indonesia sangat menyukai hewan laut satu ini untuk dijadikan olahan makanan. Dengan banyaknya masyarakat indonesia yang menyukai udang dan pastinya penjualan udang sangat menjanjikan membuat sering terjadinya pencurian dan kecurangan dalam membudidayakan tambak udang. Penggunaan kamera CCTV (Closed-Circuit Television) merupakan salah satu alternatif yang digunakan untuk memantau wilayah tambak udang. Perkembangan teknologi saat ini pada CCTV dapat melakukan pengenalan aktivitas maupun manusia serta dapat mengenali yang tertangkap oleh kamera. Proses pengenalan aktivitas dan manusia ini dilakukan dengan melihat kemiripan objek maupun aktivitas yang ingin dilakukan deteksi. Sebelum proses ini terjadi sistem melakukan analisis, deteksi dan tracking pada objek dengan menghasilkan dataset yang akan diolah menggunakan CNN (Convolutional Neural Network) yang dibantu dengan algoritma YOLO versi 8. Hasil yang didapatkan berupa label dan juga garis objek yang berhasil dideteksi. Pada proses pengenalan objek manusia didapatkan rata-rata nilai akurasi yang didapatkan dari proses deteksi manusia sebesar 80,8%. Pada pengenalan aktivitas didapatkan rata-rata akurasi aktivitas berjalan sebesar 94.25%, aktivitas berlari sebesar 75%, aktivitas jongkok sebesar 92,5%, dan aktivitas duduk sebesar 80%, sedangkan pada pengenalan objek khusus seperti petugas keamanan didapatkan akurasi sebesar 96,7%.

Baterai lithium-ion-polymer atau lithium-polymer merupakan salah satu jenis dari baterai berbasis lithium-ion. Saat ini, baterai berbasis Lithium-ion banyak digunakan pada berbagai macam perangkat portabel hingga kendaraan listrik. Pengisi daya atau charger untuk baterai berbasis Lithium-ion yang umum digunakan saat ini menggunakan metode constant current – constant voltage (CC-CV). Metode ini dianggap efektif untuk menghindari undercharging dan overcharging. Pada battery pack terdapat akumulasi resistansi yang dapat menyebabkan penurunan tegangan pada cell baterai, dan dapat mempercepat proses transisi dari mode CC menjadi mode CV. Percepatan transisi tersebut dapat mengakibatkan proses pengisian daya berlangsung lebih lama. Pada penelitian ini dibahas bagaimana proses kompensasi resistansi pada charger dengan topologi PLL, untuk mengompensasi akumulasi resistansi pada battery pack pada saat proses pengisian daya berlangsung. Pada simulasi didapatkan hasil bahwa pengisi daya dengan kompensasi resistansi menghasilkan waktu pengisian daya 17.82% lebih cepat, sedangkan pada uji coba alat didapatkan waktu pengisian daya 15.58% lebih cepat, kedua hasil tersebut jika dibandingkan dengan pengisi daya dengan topologi PLL tanpa kompensasi resistansi.

The fully relativistic self-consistent model is the Dirac–Maxwell equation where the description of spin and the magnetic field arises naturally.
In the non-relativistic setting, the correct self-consistent equation is the Schrödinger–Poisson equation which does not describe spin and the magnetic field and where the self-interaction is with the electric field only.
The Schrödinger–Poisson equation also arises as the mean field limit of the 𝑁-body Schrödinger equation with Coulomb interaction.
We propose that the Pauli–Poisson equation arises as the mean field limit

High order immersed hybridized difference methods for elliptic interface problems
Authors: Jeon Youngmok
Published: August 2023

We propose high order conforming and nonconforming immersed hybridized difference (IHD) methods in two and three dimensions for elliptic interface problems. Introducing the virtual to real transformation (VRT), we could obtain a systematic and unique way of deriving arbitrary high order methods in principle. The optimal number of collocating points for imposing interface conditions is proved, and a unique way of constructing the VRT is suggested. Numerical experiments are performed in two and three dimensions. Numerical results achieving up to the 6th order convergence in the L
2-norm are presented for the two dimensional case, and a three dimensional example with a 4th order convergence is presented.
Linguistic expressions of despondency: an investigation of Sangness-related Chinese catchwords
Authors: Song Yehui , Xue Junkai , Ma Yali , Mo Junhua
Published: August 2023

Catchwords, as important social and cultural symbols, are the barometer of a country’s society and culture. In China, various catchwords are coined and used every year by Chinese people, especially the young. Of these catchwords, one particular type that expresses despondency or Sangness is increasingly gaining scholarly attention. This study takes a socio-linguistic approach to investigating the most frequently used Sangness-related Chinese catchwords in the past ten years. By examining the annual top ten catchwords selected by Biting Words and Chewing Words between 2013 and 2022, it finds that the most frequently used Sangness-related Chinese catchwords in the past decade have been (1) Ge You Slouch, (2) feeling awful and wanting to cry, (3) Buddha-like, (4) 996 work schedule, (5) life is too hard for me, (6) laborer, (7) involution, (8) lying flat, and (9) mental internal friction. These catchwords mainly serve the functions of deconstructing mainstream values, expressing self-mockery, and seeking value recognition. The development of these Sangness-related catchwords is characterized by an increasing diversity and a stronger applicability.

Objectives

This study aimed to examine the utilization of clinical laboratory services in the emergency department and to identify the changes in their usage over six years.

Methods

Our study is a retrospective descriptive observational study. The study includes emergency room visits between January 01, 2016, and January 01, 2022, and the analysis of the tests requested during this period.

Results

When the number of tests requested among the patients in the emergency departments was considered, the highest rate belonged to complete blood count (109,696,468), which was followed by creatinine (98,027,489) and potassium (94,583,831). In addition to an increase in the number of C-reactive protein (CRP) tests (118.82 %), coagulation parameters such as D-dimer (1,180.95 %) and fibrinogen (315.25 %) showed an increasing trend after the onset of pandemia.

Conclusions

The most frequently used tests in the emergency department were complete blood count, creatinine, potassium, blood urine nitrogen (BUN), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and Na, ferritin, fibrinogen, CRP, and D-dimer have increased over the last two years due to their clinical use in predicting the outcome of COVID-19.

Published: August 2023

The article gives an idea of the development of digital economy in the European Union. Main indexes that give an integral vision of digital transformation in the EU member states are analyzed. Strengths and weaknesses of digital development of the Visegrad countries than predetermine their «lagging» position are identified. Many negative factors are of long-term nature and determine the degradation of positions that the «four» members are having during the last years. The presence of disproportional development within the scope of the Visegrad Group with the definite digital leadership of the Czech Republic was revealed. The main directions of the future digital development of the EU as a whole and the priorities of its member states, including «2030 Digital Compass», are considered. Special attention is paid to the issue of the impact of digitalization on the economy. The problem of inequality during the expansion of the digital economy is analyzed. The «Solow paradox» is confirmed as illuctrated by the Visegrad countries which indicates the existence of structural factors affecting economic dynamics, that digitalization isn’t yet able to «compensate».
