Business process modeling is an important part of organizational management since it enables companies to obtain insights into their operational workflows and find opportunities for development. However, evaluating and quantifying the similarity of multiple business process models can be difficult because these models frequently differ greatly in terms of structure and nomenclature. This study offers an approach that uses natural language processing techniques to evaluate the similarity of business process models in order to address this issue. The algorithm uses the activity labels given in the business process models as input to produce textual descriptions of the associated business processes. The algorithm includes various preprocessing stages to guarantee that the textual descriptions are correct and consistent. First, single words are retrieved and transformed to lower case from the resulting textual descriptions. After that, all non-alphabetic and stop words are removed from the retrieved words. The remaining words are then stemmed, which includes reducing them to their base form. The algorithm evaluates the similarity of distinct business process models using similarity measures, including Jaccard, Sorensen – Dice, overlap, and simple matching coefficients, after the textual descriptions have been prepared and preprocessed. These metrics provide a more detailed understanding of the similarities and differences across various business process models, which can then be used to influence decision-making and business process improvement initiatives. The software implementation of the proposed algorithm demonstrates its usage for similarity measurement in a database of business process models. Experiments show that the developed algorithm is 31% faster than a search based on the SQL LIKE clause and allows finding 18% more similar models in the business process model database.

Authors: Chalyi Serhii , Leshchynska Irina
Published: July 2023

The subject of research is the process of formation of explanations in artificial intelligence systems. To solve the problem of the opacity of decision-making in artificial intelligence systems, users should receive an explanation of the decisions made. The explanation allows you to trust these solutions and ensure their use in practice. The purpose of the work is to develop a conceptual mental model of explanation to determine the basic dependencies that determine the relationship between input data, as well as actions to obtain a result in an intelligent system, and its final solution. To achieve the goal, the following tasks are solved: structuring approaches to building mental models of explanations; construction of a conceptual mental model of explanation based on a unified representation of the user's knowledge. Conclusions. The structuring of approaches to the construction of mental models of explanations in intelligent systems has been carried out. Mental models are designed to reflect the user's perception of an explanation. Causal, statistical, semantic, and conceptual approaches to the construction of mental models of explanation are distinguished. It is shown that the conceptual model sets generalized schemes and principles regarding the process of functioning of the intellectual system. Its further detailing is carried out on the basis of a causal approach in the case of constructing an explanation for processes, a statistical approach when constructing an explanation about the result of the system's work, as well as a semantic approach when harmonizing the explanation with the user's basic knowledge. A three-level conceptual mental model of the explanation is proposed, containing levels of concepts regarding the basic principles of the functioning of the artificial intelligence system, an explanation that details this concept in an acceptable and understandable way for the user, as well as basic knowledge about the subject area, which is the basis for the formation of the explanation. In a practical aspect, the proposed model creates conditions for building and organizing a set of agreed explanations that describe the process and result of the intelligent system, considering the possibility of their perception by the user.

Computational thinking is an essential concept that has attracted the attention of early childhood educators over the last decade. However, not all kindergarten teachers have yet obtained information and ideas related to computational thinking skills. This study attempts to determine the effectiveness of active distance learning using a zoom video conference application in improving teachers' computational thinking skills. Furthermore, it also examines the teachers' progress in learning computational skills through online coding websites such as code.org and ScratchJr. A hundred and sixty-three kindergarten teachers from Central Java Province in Indonesia participated in the study. The study used a quantitative approach and employed a pre-experimental design, one group pretest and a post-test study. The data were gathered through pretest, post-test, and reflection of assignment records. We employed the Wilcoxon test because our data are on the ordinal scale. Wilcoxon signed-rank test was utilized to find out the significance of distance learning. The results show active distance learning effectively enhances teachers' computational thinking skills. Moreover, active distance learning provides an impressive experience to participants in improving their mastery of computational thinking.

Keterkaitan Hukum Perdagangan Internasional Dan Investasi Serta Manfaat Dan Kekurangan Perdagangan Internasional Dan Investasi
Authors: Aflah  , Budi Utomo Satrio , Hasibuan Puspa Melati
Published: July 2023

Perdagangan Internasional dan investasi adalah dua konsep penting dalam perekonomian global saat ini, dimana pada era ini segala bentuk kebutuhan manusia mulai berkembang mulai dari kebutuhan premier, sekunder, dan tersier. Perdagangan internasional adalah pertukaran barang dan jasa antara negara-negara yang terikat dalam kesepakatan baik bilateral, multilateran, hingga tingkat konvensi. Sementara investasi memiliki karakteristik yang serupa dengan perdagangan internasional namun dalam bentuk modal, melibatkan aliran modal dari satu negara ke negara lain untuk membeli aset atau saham dalam suatu perusahaan ataupun juga mendirikan suatu perusahaan di negara tempat penanaman modal dilakukan. Perdagangan Internasional memungkinkan negara-negara untuk memperluas pasar mereka dan mengakses sumber daya yang tidak tersedia di negara mereka sendiri. Ini dapat meningkatkan pertumbuhan ekonomi dan menciptakan lapangan kerja. Namun, perdagangan internasional juga dapat menyebabkan persaingan yang ketat dan dapat memengaruhi sektor industri tertentu di negara-negara yang kurang kompetitif. Investasi asing juga dapat memiliki dampak yang signifikan pada perekonomian suatu negara. Investasi asing langsung dapat membantu menciptakan lapangan kerja, meningkatkan produktivitas, dan mengalirkan teknologi baru ke negara-negara penerima investasi. Namun, investasi asing juga dapat memengaruhi kedaulatan ekonomi negara penerima, terutama jika perusahaan asing memiliki kontrol yang signifikan atas sumber daya dan infrastruktur kunci di negara tersebut. Oleh karena itu penelitian ini dilakukan untuk menganalisa hubungan, pengaturan, serta manfaat dan dampak negatif dari perdagangan Internasional dan Investasi demi menjaga kestabilan dalam bidang ekonomi serta politik, kepentingan nasional dan global serta dengan mengadopsi kebijakan yang dapat mendorong pertumbuhan ekonomi dan melindungi kepentingan nasional dalam jangka panjang.

Preliminary testing of expedient ground anchor solutions for guyed towers in remote cold regions : considerations for cold remote regions with limited tools
Authors: Bjella Kevin , Vandevort Daniel , Kopczynski Sarah
Published: July 2023

Ground anchors connected to guy wires for tower structures in cold climates suffer from frost heaving, which causes loss of wire tension and subsequent structural instability. It is necessary to understand what ground anchors are available to resist this tendency yet are still capable of expedient installation in remote areas. To that end, three metal, traditional ground-anchor types (arrowhead, bullet, and penetrating auger) and one novel polyvinyl chloride (PVC) T-post anchor were evaluated in frozen gravels and frozen silts at a research facility in Fairbanks, Alaska. Criteria included installation capability, failure loading, and removal ability. Additionally, expedient installation techniques for use in field conditions were also demonstrated. All three traditional ground anchors failed to penetrate frozen gravels. The penetrating auger also failed to penetrate frozen silts, but the arrowhead and bullet anchors did penetrate frozen silts with difficulty. The PVC anchor is capable of being installed only in a predrilled pilot hole. Under flexural load, the arrowhead anchor cable failed at 3686.72 lb, and the bullet anchor cable failed at 1753.44 lb. The PVC slid out of its hole at a direct-pull force of 1978.24 lb and failed under flexural stress at 202.32 lb.

Passive fit of CAD/CAM implant supported screw-retained metal frameworks based on actual versus screwmented ones based on virtual implant position: A randomized in vitro study
Authors: Kamel Mohamed El-Sayed
Published: July 2023

CAD/CAM (computer aided design/ computer aided manufacturing) constructed screw retained implant supported frameworks give solutions for the problems arising from the lost wax technique by improving accuracy, adaptation and passive fit of the final restoration. However, concerns about the passive fit of a pre-implant insertion CAD/CAM constructed framework still exists due to the expected errors in imaging, registration, surgical guide construction, adaptation and hence transferring the planned position intra-orally.
Trends of Carbon Emissions and Foreign Direct Investment: Accounting for Ecological Footprints, Renewable Energy, Globalization and Technological Innovations in BRICS
Authors: Kayani Umar Nawaz , Nasim Ismat , Aysan Ahmet Faruk , Bashir Farrukh , Iqbal Umer
Published: July 2023

This paper explores the relationship between carbon emission (CE) and foreign direct investment (FDI) keeping the ecological footprint, renewable energy, globalization, and technological innovations as exogenous variables. We employ the system of equations in the form of simultaneous equations for the panel of BRICS countries to fully capture the proposed association. This study highlights the importance of ecological footprints for the determination of CE and FDI along with some exogenous and instrument variables. Our empirical findings of explaining CE assert that FDI, technological innovations, and renewable energy significantly help to curtail carbon emissions in selected countries. However, the ecological footprints are causing CE positively which yields an alarming situation in two ways, firstly a high of rate environmental degradation, and secondly the pressure of humans on land is increasing and that is causing to increase in the EF in BRICS. The equation of FDI is presenting the curtailing impact of CE and RER whereas globalization is increasing the investment rate in BRICS. Mineral mining should be controlled and regulated since it has the potential to have a number of negative effects, including soil pollution, acid mine drainage, erosion, biodiversity loss, considerable water resource usage, and problems with wastewater disposal. Nonetheless, recycling mining waste, employing environmentally friendly equipment, stopping illegal mining, and enhancing mining sustainability may all help to lessen the effects of mining on the environment.
Comparison of Chloroplast Genomes and Phylogenetic Analysis of Four Species in Quercus section Cyclobalanopsis
Authors: Chen Xiaoli , Zhang Xuemei
Published: July 2023

The identification in Quercus L. species was considered to be difficult all the time. The fundamental phylogenies of Quercus have already been discussed by morphological and molecular means. However, the morphological characteristics of some Quercus groups may not be consistent with the molecular results (such as the group Helferiana ), which may lead to blurring of species relationships and prevent further evolutionary researches. To understand the interspecific relationships and phylogenetic positions, we sequenced and assembled the CPGs (160715 bp ~ 160842 bp) of four Quercus section Cyclobalanopsis species by Illumina pair-end sequencing. The genomic structure, GC content and IR/SC boundaries exhibited significant conservatism. Six highly variable hotspots were detected in comparison analysis, among which rpoC1, clpP and ycf1 could be used as molecular markers. Besides, two genes (petA, ycf2) were detected to be under positive selection pressure. The phylogenetic analysis showed: Trigonobalanus genus and Fagus genus located at the base of the phylogeny tree; the Quercus genus were distincted to two clades, including five sections. All CTB species clustered into a single branch, which was in accordance with the results of the morphological studies. But neither of group Gilva nor group Helferiana had formed a monophyly. Six CTB species gathered together in pairs to form one branch respectively (Quercus kerrii and Quercus chungii; Quercus austrocochinchinensis with Quercus gilva; Quercus helferiana and Quercus rex). Due to a low support rate (0.338) in the phylogeny tree, the interspecies relationship between the two branches differentiated by this node remained unclear. We believe that Q. helferiana and Q. kerrii can exist as independent species due to their distance in the phylogeny tree. Our study provided genetic information in Quercus genus, which could be applied to further studies in taxology and phylogenetics.
Vibrational Spectroscopy Identifies Myocardial Chemical Modifications in 1 Heart Failure with Preserved Ejection Fraction
Authors: Pioppi Leonardo , Parvan Reza , Samrend Alan , Silva Gustavo Jose Justo da , Paolantini Marco , Sassi Paola , Cataliotti Alessandro
Published: July 2023

Background
Vibrational spectroscopy can be a valuable tool to monitor the markers of cardiovascular diseases. In the present work, we explored the vibrational spectroscopy characteristics of the cardiac tissue in an experimental model of heart failure with preserved ejection fraction (HFpEF). The goal was to detect early cardiac chemical modifications associated with the development of HFpEF.
Methods
We used the Fourier-transform infrared (FTIR) and Raman micro-spectroscopic techniques to provide complementary and objective tools for the histological assessment of heart tissues from an animal model of HFpEF. A new sampling technique was adopted (tissue print on a CaF2 disk) to characterize the extracellular matrix.
Results
Several spectroscopic markers (lipids, carbohydrates, and glutamate bands) were recognized in the cardiac ventricles due to the comorbidities associated with the pathology, such as obesity and diabetes. Besides, abnormal collagen cross-linking and a decrease in tryptophan content were observed and related to the stiffening of ventricles and to the inflammatory state which is a favourable condition for HFpEF.
Conclusions
By the analyses of tissues and tissue prints, FTIR and Raman techniques were shown to be highly sensitive and selective in detecting changes in the chemistry of the heart in experimental HFpEF and its related comorbidities. Vibrational spectroscopy is a new approach that can identify novel biomarkers for early detection of HFpEF.
Implementing PCR testing in general practice – a qualitative study using normalization process theory
Authors: Shahrzad Sinead , Balasubramaniam Kirubakaran , Kousgaard Marius Brostrøm , Thilsing Trine , Søndergaard Jens , Overbeck Gritt
Published: July 2023

Background
The covid-19 pandemic brought attention to a need of rapid testing of large populations. Experiences from community-based testing settings show that there can be workload difficulties, logistical challenges, and socioeconomic downsides to large scale Polymerase Chain Reaction (PCR) testing. Alternative testing arenas have therefore been considered. Rapid point-of-care (POC) PCR test methods have since been developed and could have potential to surveille respiratory viral infections. It is, however, unknown if PCR testing can be successfully implemented routinely in general practice. The aim of this study is therefore to asses factors that enable and inhibit the implementation of point-of-care PCR testing for acute respiratory tract infection in general practice.
Methods
Fourteen general practices in the east Zealand area in Denmark were included in the study and given access to point-of-care PCR testing equipment during a flu season. The participating clinics were initially trained in the use of a POC PCR testing device and then spent 6 weeks testing it. We conducted qualitative interviews with general practitioners (GPs) and their staff, before and after the testing period, specifically focusing on their clinical decision-making and internal collaboration in relation to POC PCR testing. We used normalization process theory to design the interview guides and to analyze the data.
Results
Professionals reported no clinical need for a POC PCR testing device in a non-pandemic clinical setting. Results were delivered faster, but this was only timesaving for the patient and not the GP, who had to perform more tasks.
Conclusion
In its current form, the added diagnostic value of using a POC PCR tester in clinical practice does not justify the increased work connected to the usage of the diagnostic procedure in daily practice.

Since late 2021, highly pathogenic avian influenza (HPAI) viruses of the A/goose/Guangdong/1/1996 (H5N1) lineage have continued to cause widespread mortality in wild birds and poultry in the United States. Concomitant with the spread of HPAI viruses in birds are increasing numbers of mammalian infections, including wild and captive mesocarnivores and carnivores with central nervous system involvement. Here we report the first known case of HPAI, A(H5N1) of clade 2.3.4.4b, in a common bottlenose dolphin (Tursiops truncatus) from Florida, United States. Pathological findings included neuronal necrosis and inflammation of the brain and meninges, and quantitative real time RT-PCR revealed the brain carried the highest viral load of tissues tested. Virus isolated from the brain contained a S246N neuraminidase substitution which led to reduced inhibition by the neuraminidase inhibitor oseltamivir. The increased prevalence of A(H5N1) viruses in atypical avian hosts and its cross-species transmission into mammalian species highlights the public health importance of continued disease surveillance and biosecurity protocols.

Zabrotes subfasciatus (Boheman) is one of the main pests of storage beans, affecting common bean (Phaseolus vulgaris L.) in tropical world regions. The aim of this study was to evaluate antixenosis of two P. vulgaris genotypes to Z. subfasciatus and the emission of volatile compounds from seeds of these genotypes. Antixenosis in adults and oviposition was evaluated using the obligate antibiosis test, on ‘G11051’ and ‘ICA Pijao’ genotypes of common bean to Z. subfasciatus. The volatile compounds of their seeds related to antixenosis were also evaluated. The number of adult insects away from seeds, the percentage of eggs in seeds and the container and the number of total eggs were counted. The presence of volatile compounds was determined by headspace solid-phase microextraction coupled with gas chromatography - mass spectrometry (HS-SPME-GC-MS). Genotype ‘G11051’ showed higher adult antixenosis (80 % non-preference) and antixenosis by oviposition on their seeds than ‘ICA Pijao’ genotype which showed only 11 % repellency. Significant statistical differences were found in the volatile compounds detected. ‘G11051’ showed 65 compounds and 22 specific to this genotype, while in ‘ICA Pijao’, 53 compounds were detected, eight of which were specific to this genotype. Of these, dimethyl disulfide, limonene, (E)-2-hexenal and hexanal showed known antixenotic activity.
Effectiveness and safety of digital rectal stimulation and abdominal massage for neurogenic bowel dysfunction in stroke patients: a randomized controlled trial protocol
Authors: Ma Sumin , Fan Xiaoyan , Li Chengjuan , Man Yanli , Qu Dandan , He Ying
Published: July 2023

Background
Neurogenic bowel dysfunction (NBD) is a prevalent complication among stroke patients, significantly affecting their quality of life, hospitalization duration, medical expenses, and even mortality. Although current guidelines suggest a conservative approach to managing bowel dysfunction, incorporating techniques such as digital rectal stimulation (DRS) and abdominal massage, the availability of other interventions remains limited in healthcare facilities. Therefore, it’s crucial to develop accessible and targeted rehabilitation programs that can improve both bowel function and quality of life for stroke patients. The aim of this study is to evaluate the effectiveness of a 6-week rehabilitation program for stroke patients with NBD.

Positional Dynamics in Competition: Introducing Targeted Position Games
Authors: Farshi Esmaeil
Published: July 2023

Modern competitive scenarios often demand more nuanced strategies than merely winning or losing. This has given rise to Targeted Position Games (TPGs), which shift the focus from outright maximization to achieving specific targeted rankings. In this paper, we formalize the concept of TPGs and delve into their intricate dynamics. We derive foundational theorems, establishing the existence of mixed strategy equilibria and exploring the influence of strategic foresight. Particularly interesting is the parallel between TPGs and the quantum world, where the Pauli Exclusion Principle dictates electron behavior, providing a unique equilibrium that echoes the results from our TPGs framework. We also extend the TPGs analysis into areas of information asymmetry, emphasizing the role of prediction in strategy formulation. Further, we shed light on how TPGs can offer valuable insights for artificial intelligence and the digital economy, shaping the way we think about ranking, competition, and strategic decision-making. This work paves the way for a new understanding of competitive positioning and its extensive potential applications.

Ever-increasing global warming and human disruptions have resulted in unprecedented frequency, spread and intensity of destructive wildfires across continents. Thus, effective systems to tackle this are the need of the hour. “Forest Guard” is an integrated dispersed multi-variable sensor network cum AI-based system that promises pre-emptive prediction of fire-prone areas and proactive detection of wildfires. A deep learning AI model classifies the forest area on the basis of a numerical % probability of forest fire occurrence, calculated according to value intensity and degree of correlation between moving averages of parameters like Atmospheric. Temperature, Humidity and Soil Moisture gathered from sensors and other static variables. It then plots a color encoded percentage risk assessment map after extrapolating individual sensor node results to an area of 0.031km2. As this is a novel approach, the model was trained on reinforcement learning and tested on 3 simulations of 10000 data points each. It received accuracy of 98% ± 2%. Forest Guard detects distinctive wildfire and bird (distress-callings) sounds through analyzing and differentiating sounds recorded every 2 minutes by running them through a short Fast-Fourier-Transformation Deep Learning model and then raises a preliminary alarm. A confirmatory fire alarm is raised after the algorithm detects simultaneous sudden deviations with respect to the calibrated baseline in continuously monitored parameters (Atmospheric. Temperature, Humidity, Smoke, Soil Temperature and Moisture). As tested in 3 different control burns of 2500m2 each(avg.), the fire was detected within 2-3minutes (Minimum- time recorded- Preliminary-Alarm- 2:23 minutes, Confirmatory-Alarm- 3:58 minutes from ignition). All simulations/ experiments proved the hypothesis of using localized/ on-ground parameters for detection/prediction.

Diabetic patients constitute one of the most vulnerable subgroups in COVID-19. Despite high vaccination rates, a correlate of protection to advise vaccination strategies for novel SARS-CoV2 variants of concern and lower mortality in this high-risk group is still missing. It is further unclear what antibody levels provide protection and whether pre-existing organ damage affects this threshold. To address these gaps, we conducted a prospective multicenter cohort study on 1152 patients with COVID-19 from five hospitals. Patients were classified by diabetes and vaccination status. Anti-SARS-CoV-2-spike-antibodies, creatinine and NTproBNP were measured on hospital admission. Pre-specified endpoints were all-cause in-hospital-mortality, ICU admission, endotracheal intubation, and oxygen administration. Propensity score matching was applied to increase comparability. We observed significantly lower anti-SARS-CoV2-spike-antibodies in diabetic non-survivors compared to survivors (mean, 95%CI; 351U/ml, 106–595 vs. 1123, 968–1279, p < 0.001). Mortality risk increased two-fold with each standard deviation-decrease of antibody levels (aHR 1.988, 95%CI 1.229–3.215, p = 0.005). Diabetic patients requiring oxygen administration, endotracheal intubation and ICU admission had significantly lower antibody levels than those who did not (p < 0.001, p = 0.046, p = 0.011). While diabetic patients had significantly worse outcomes than non-diabetic patients, the differences were less pronounced compared to propensity-score-matched non-diabetic patients. Anti-SARS-CoV2 spike antibodies on hospital admission are inversely associated with oxygen administration, endotracheal intubation, intensive care and in-hospital mortality in diabetic COVID-19 patients. Pre-existing comorbidities may have a greater impact on outcome than diabetes status alone.

Environmental challenges have become a matter of great concern, requiring immediate attention. Agricultural pollution, such as ammonia discharge, and industrial pollution, including the abuse of organic dyes, present significant dilemmas for humanity. In response to these challenges, we propose an approach by synthesizing TiO2-CuO hetero-nanoparticles capable of degrading multiple hazardous environmental substances. Submerged photosynthesis of crystallites (SPSC) can synthesize or assist in the synthesis of metal oxides due to its simplicity and environmentally friendly nature. TiO2-CuO hetero-nanoparticles with varying Cu-Ti molar ratios were prepared, characterized, and evaluated for performance. The dispersion of CuO within TiO2 was found to be relatively uniform. Increasing the amount of added Cu resulted in an increase in CuO content until reaching the upper limit. Despite minor variations, all hetero-nanoparticle samples exhibited excellent solar light absorption performance. The simultaneous utilization of solar light illumination and electrochemical techniques synergistically enhanced the degradation process of these hazardous substances. The hetero-nanoparticle with a Cu-Ti molar ratio of 0.17 demonstrated the optimal photo-electrochemical degradation performance, exhibiting a 150% increase in degradation efficiency under solar light illumination compared to dark condition. Furthermore, it exhibited superior efficiency in the electrochemical degradation of RhB under solar light, degrading 32% more than solar light alone, and 2% more than electrochemistry alone. The mechanisms behind the fabrication and degradation processes were also discussed, elucidating the underlying principles driving the observed performance. In conclusion, our research highlights the potential of TiO2-CuO hetero-nanoparticles for solar light-assisted degradation of NH3 and RhB, showcasing their environmental applications.

This study aimed to investigate the relationship of four chronic kidney disease–mineral and bone disorder (CKD–MBD) biomarkers, including intact parathyroid hormone (PTH), fibroblast growth factor 23 (FGF23), soluble klotho, and fetuin-A, with aortic stiffness in peritoneal dialysis (PD) patients, comparing those with and without diabetes mellitus (DM). A total of 213 patients (mean age 58 ± 14 years; 81 (38.0%) patients with DM) were enrolled. Their aortic pulse wave velocity (PWV) was measured using pressure applanation tonometry, while serum intact PTH, FGF23, α-klotho, and fetuin-A levels were measured using enzyme-linked immunosorbent assay. Overall, patients with DM had higher aortic PWV than those without (9.9 ± 1.8 versus 8.6 ± 1.4 m/s, p < 0.001). Among the four CKD–MBD biomarkers, FGF23 levels were significantly lower in DM group (462 [127–1790] versus 1237 [251–3120] pg/mL, p = 0.028) and log-FGF23 independently predicted aortic PWV in DM group (β: 0.61, 95% confidence interval: 0.06–1.16, p = 0.029 in DM group; β: 0.10, 95% confidence interval: −0.24–0.45, p = 0.546 in nonDM group; interaction p = 0.016). In conclusion, the association between FGF23 and aortic PWV was significantly modified by DM status in PD patients.
