The Application of the Modified Prim's Algorithm to Restore the Power System Using Renewable Energy Sources

The recent trends in the development of power systems are focused on the Self-Healing Grid technology fusing renewable energy sources. In the event of a failure of the power system, automated distribution grids should continue to supply energy to consumers. Unfortunately, there are currently a limited number of algorithms for rebuilding a power system with renewable energy sources. This problem is possible to solve by implementing restoration algorithms based on graph theory. This article presents the new modification of Prim’s algorithm, which has been adapted to operate on a power grid containing several power sources, including renewable energy sources. This solution is unique because Prim’s algorithm is ultimately dedicated to single-source graph topologies, while the proposed solution is adapted to multi-source topologies. In the algorithm, the power system is modeled by the adjacency matrices. The adjacency matrixes for the considered undirected graphs are symmetric. The novel logic is based on the original method of determining weights depending on active power, reactive power and active power losses. The developed solution was verified by performing a simulation on a test model of the distribution grid powered by a renewable energy source. The control logic concept was compared with the reference algorithms, which were chosen from the ideas representing available approaches based on graph theory present in the scientific publications. The conducted research confirmed the effectiveness and validity of the novel restoration strategy. The presented algorithm may be applied as a restoration logic dedicated to power distribution systems.
Characterization of Vaccine Breakthrough Cases during Measles Outbreaks in Milan and Surrounding Areas, Italy, 2017–2021

Despite the existence of an effective live-attenuated vaccine, measles can appear in vaccinated individuals. We investigated breakthrough measles cases identified during our surveillance activities within the measles/rubella surveillance network (MoRoNet) in Milan and surrounding areas (Northern Italy). Between 2017 and 2021, we confirmed measles virus (genotypes B3 or D8) infections in 653 patients and 51 of these (7.8%) were vaccinees. Among vaccinated individuals whose serum was available, a secondary failure was evidenced in 69.4% (25/36) of cases while 11 patients (30.6%) were non-responders. Non-responders were more frequently hospitalized and had significantly lower Ct values in both respiratory and urine samples. Median age and time since the last immunization were similar in the two groups. Importantly, we identified onward transmissions from vaccine failure cases. Vaccinees were involved in 20 outbreaks, in 10 of them they were able to transmit the virus, and in 8 of them, they were the index case. Comparing viral hemagglutinin sequences from vaccinated and non-vaccinated subjects did not show a specific mutation pattern. These results suggest that vaccination failure was likely due to the poor immune response of single individuals and highlights the importance of identifying breakthrough cases and characterizing their clinical and virologic profiles.
Comparative effect of Gong’s mobilization and Spencer technique to manage Frozen Shoulder

Introduction. Physical therapy plays a significant role in managing frozen shoulder (FS), and it includes applying manual mobilization techniques to reduce pain, restore the extensibility of the shoulder capsule and increase range of motion (ROM). Objective: To compare the effectiveness of Gong's mobilization (GM) and Spencer technique (ST) in reducing pain, functional disability, and improving shoulder ROM on FS patients. Methods. A pre-and-post-test experimental study design was adopted, where thirty patients ( n = 30) diagnosed with unilateral FS were selected and randomized into two groups of 15 using a simple random technique. Subjects in experimental group 1(EG-I) received ST technique and ultrasound therapy (US), with Codman’s pendular exercise (CPE). Whereas experimental group II (EG-II) received GM technique and US, with CPE. The intervention lasted five days and consisted of one session every day. Three variables were assessed to study the treatment effectiveness both at the pre-intervention and at the end of the first week: (i) pain intensity as measured by the Visual Analogue Scale; (ii) shoulder ROM as measured by a goniometer (abduction, flexion, and medial rotation (MR)); and (iii) functional disability as measured by SPADI (Shoulder Pain Disability Index). Results. The EG-II showed a better reduction in pain intensity (mean difference (MD) of 0.87), SPADI (MD of 7), and increase in shoulder ROM (MD: 'abduction': 15.76; ‘Flexion’: 15.67; ‘MR’: 10.33) than the EG-I at 0.05 levels of significance. Conclusions. Gong’s mobilization was found to be more effective than Spencer's technique with ultrasound therapy and CPE in treating patients with FS. frozen shoulder, a wide range of beneficial treatments, both surgical and non-surgical, are available. The therapeutic management of frozen shoulder frequently differs significantly across clinicians and is based on personal experience rather than published research. This study contributed to the body of knowledge that both Gong's mobilization and the Spencer technique are found to have short-term effects on pain, functional disability, and shoulder range of motion. Further, Gong's mobilization is found to be more clinically significant than Spencer's approach, with greater improvements in shoulder flexion, abduction, medial rotation ROM, and functional disability. In addition, the study also provides evidence to the clinicians that Gong's mobilization with ultrasound therapy and a unique set of Codman pendular exercises can be used in combination with the physiotherapy treatment plan for patients with frozen shoulders. From the patients’ perspectives, this study’s findings will help understand the causes of frozen shoulder and how to manage it physiotherapeutically with the latest advanced techniques with pain-free, immediate, and short-term improvement. This study will also add evidence to the researcher’s knowledge of combined therapeutic interventions' effectiveness in managing
Rapid genomic profiling of circulating tumor DNA in non-small cell lung cancer using Oncomine Precision Assay with Genexus™ integrated sequencer

Background Genomic profiling of tumors from cancer patients facilitates molecular-guided therapy. The turnaround time is one of important issues to deliver results timely for clinical decisions. The Ion Torrent™ Genexus™ Integrated Sequencer automates all next generation sequencing (NGS) workflows and delivers results within a day. Methods In this study, we conducted a feasibility study to evaluate the detection rate of genomic alterations from cell-free total nucleic acid (cfTNA, containing cfDNA and cfRNA) of 119 non-small cell lung cancer using Oncomine Precision Assay on Genexus™ Integrated Sequencer. Oncomine Precision Assay (OPA) covers actionable mutations, copy number variations and fusion genes and that are applicable for the selection of targeted therapy. cfTNA isolated from plasma (derived from 14 ml of blood) were subjected to the Genexus system for library construction, templating, sequencing, and data analyses. Results The sequencing resulted in median overall depth of 35,773× and median molecular coverage of 2,192× with cfTNA input ranged from 11 to 36 ng. Among the 119 samples evaluated, we detected at least one genomic alteration in plasma cfTNA of 79 cases (66%). When comparing to standard-of-care testing, the sensitivity and specificity of mutation detection in non-small cell lung cancer related genes using liquid biopsy with Genexus-OPA ranged between 49–67% and 93–100%, respectively. 59% of actionable mutations, which were present in tumor tissues, were detected by the Genexus- Oncomine Precision Assay using plasma cfTNA. Among the 5 mutations detected from liquid biopsy only, three mutations are of level 1 evidence according to OncoKB database, highlighting the clinical utilities of liquid biopsy in addressing tumor heterogeneity. Extrathoracic metastasis and levels of lactate dehydrogenase (LDH), C-reactive protein (CRP) and Carcinoembryonic Antigen (CEA) are found to be associated with increased circulating tumor DNA detection. Conclusions The Genexus™ Integrated Sequencer system is an automated, accurate NGS system with short turnaround time (TAT) that could assist clinicians to make more timely decision.
Synthesis and Antioxidant Activity of Silver Nanoparticles Using the Odontonema strictum Leaf Extract

The aqueous extract of the leaves of Odontonema strictum (OSM) is used in folk medicine for its antihypertensive properties, and it contains a wide range of secondary metabolites, mostly polyphenols such as verbascoside and isoverbascoside, which could play a major role in the preparation of silver nanoparticles. In this study, we aimed to prepare AgNPs for the first time using the OSM leaf extract (OSM-AgNPs) to investigate their free radical-scavenging potency against 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydrogen peroxide (H2O2). Dynamic light scattering (DLS), UV/Vis, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), and X-ray photoelectron spectroscopy (XPS) were used to characterize the OSM-AgNPs. With a size around 100 nm and a ζ-potential of −41.1 mV, OSM-AgNPs showed a good stability and a better colloidal property due to electrostatic repulsion and the dispersity. The strong absorption peak at 3 keV in the EDX spectra indicated that silver was the major constituent. Additionally, the existence of silver atoms was confirmed by the Ag 3d5/2 peak around 367 eV in the XPS spectra. IC50 values of 116 μg/mL and 4.4 μg/mL were obtained for the scavenging activities of DPPH and H2O2, respectively. The synthetic OSM-AgNPs can be further exploited as potential antioxidant agents.
How Knowledge Services Clustered Firms Leverage Different Channels of Local Knowledge Spillovers for Service Innovation

ABSTRACT Built upon configuration theory, this study performs a Qualitative Comparative Analysis (QCA) to delineate alternative and sufficient configurations of local knowledge spillover (LKS) channels, that is, how informal interactions and spinoff, and absorptive capacity are combined to facilitate service innovation. Primary data was collected from the largest software outsourcing cluster in Vietnam in 2018, which provides a sample size of 42 firms. The findings imply that multiple configurations of different channels of LKS in conjunction with absorptive capacity can lead to service innovation. This study makes three important contributions. First, it contributes to the debate over the critical role of LKS and absorptive capacity in innovation by offering a more holistic, yet nuanced understanding of the causal mechanisms underlying service innovation. Second, this study sheds light on viable and equifinal pathways for enhancing innovation capabilities, therefore contributing to the literature on cluster upgrading and global service sourcing. Third, it provides some managerial implications for indigenous spinoff firms in developing countries seeking to innovate through the strategic use of LKS. 摘要 本文基于配置理论使用了量化比较分析的方法来区分两种本地只是溢出渠道的配置方法—可供替代的和充足的配置，也即非正式交往和衍生品，应如何与组织吸收能力相结合来促进服务创新。 作者于2018年在越南最大的软件外包集群搜集了42家公司的数据。 分析表明存在本地知识溢出不同渠道的多种配置方式，都可以与公司的吸收能力加以组合来达到服务创新的目的。
Room Temperature Engineering Crystal Facet of Cu2O for Photocatalytic Degradation of Methyl Orange

Cuprous oxide (Cu2O) has received enormous interest for photocatalysis owing to its narrow band gap of 2.17 eV, which is beneficial for visible-light absorption. In this work, we succeeded in synthesizing Cu2O nanocrystals with two morphologies, cube and sphere, at room temperature via a simple wet-chemistry strategy. The morphologies of Cu2O change from cube to sphere when adding PVP from 0 g to 4 g and the mainly exposed crystal faces of cubic and spherical Cu2O are (100) and (111), respectively. The photocatalytic properties of the as-prepared Cu2O were evaluated by the photocatalytic degradation of methyl orange (MO). Cubic Cu2O(100) showed excellent photocatalytic activity. After the optical and photoelectric properties were investigated, we found that cubic Cu2O(100) has better photoelectric separation efficiency than spherical Cu2O(111). Finally, the possible mechanism was proposed for cubic Cu2O(100) degrading MO under visible light.
Design Simulation and Assessment of Prediction of Mortality in Intensive Care Unit Using Intelligent Algorithms

Big data in healthcare refers to vast amounts of data generated by the adoption of digital technology that collect patient records and aid in the management of hospital performance, which would otherwise be too large and complex for traditional technologies. We have chosen Mortality Prediction in Hospital ICU for this paper. In recent years, there has been a determined push in hospitals to implement digital health record systems. Between 2008 and 2014, the number of non-federal acute care hospitals in the United States using basic digital systems climbed from 9.4 percent to 75.5 percent. In the near future, the percentage increase in the hospital's digital information will be enormous, and we will need to apply modern big data techniques to analyse those datasets. In the best sense, the future of medical diagnosis and therapy is a combination of medical judgement and an algorithmic diagnostic tool based on large medical information. For our research, we used the MIMIC III database. In this paper, we will go over why Mortality Prediction in ICU is interesting, as well as the method we used to examine and address the problem.
Growth Performance of Native Tropical Tree Species on a Coal Mine Spoil on Singrauli Coalfields, India

Abstract A study was conducted to assess the growth performance of eight native tropical tree species planted on a coal mine spoil on Singrauli Coalfields, India. Of all the investigated tree species Acacia catechu, Albizia lebbeck, Dalbergia sissoo and Millettia pinnata were represented by the leguminous species while Azadirachta indica, Gmelina arborea, Tectona grandis and Terminalia bellerica were represented by the non-leguminous species. The overall performance of the leguminous tree species was greater than the non-leguminous tree species. Among all the studied tree species, the leguminous Albizia lebbeck was the best performing species while the non-leguminous Terminalia bellerica was the poorest performing tree species on coal mine spoil. Gmelina arborea and Azadirachta indica were the best performing tree species among the non-leguminous species.

Mechanical properties of underpinning joints in structural moving: Experiments and numerical modeling

Underpinning is a key component in the structural moving process, especially for high‐rise buildings with gravitational loads. In this paper, a most commonly used 4‐sided wrapped underpinning joint with 2 underpinning beams and 2 coupling beams for the frame structures was investigated. Sixteen prototypes were tested considering different shear span‐to‐depth ratios, underpinning joint heights, reinforcement ratios, and so forth. The experimental results showed that the underpinning beams can fail in shear or flexure‐shear. The interface between the column and the beam is also prone to failure during the loading. Further, the bearing capacity can be greatly improved with decreasing of the shear span‐to‐depth ratio, whereas more damage may occur within the interface domain. In the numerical simulations, a damage–plasticity constitutive model was adopted, and the cohesive elements were used to model the old‐to‐new concrete interface between the column and beams. It was found that the numerical results agreed quite well with the experimental results. Thus, the proposed approach can be a useful basis for further analysis and optimized design of underpinning joints.
Title-comparison of coronally advanced flap with chorion membrane vs coronally advanced flap with connective tissue graft in the treatment of multiple gingival recessions: a split-mouth randomised controlled study

Background: The importance of esthetics has escalated over the years. The purpose of any perioplastic surgery is to address gingival recession while ensuring predictable root coverage and a pleasing appearance. An array of surgical procedures have been recommended for the management of recession defects. The present study compares the clinical and patient related outcome measures of coronally advanced flap with chorion membrane and connective tissue graft in the management of multiple adjacent gingival recessions. Methods: The study was a prospective randomized controlled trial which included eight systemically healthy patients with an age range of 30-44 years with 36 labial/buccal, multiple adjacent, Cairo’s RT1 gingival recession defects, bilaterally. CAF+CM was performed on one side whereas CAF+CTG was performed on the other side. The two groups were compared clinically at three and six months postoperatively. Results: There was statistically significant decrease in recession depth, recession width, probing depth and clinical attachment level in both the groups from baseline to three and six months. However, intergroup comparisons revealed no statistically significant difference. At six months, both groups showed statistically significant improvements in keratinized tissue width and gingival thickness. The gingival thickness of the CAF+CM group increased significantly at three and six months. In terms of root coverage aesthetic score (RES), there was no significant difference observed between the two groups. In terms of patient reported outcome measures (PROMS), patients preferred the CAF+CM technique. Conclusion: Within the limits of the current study, the use of chorion membrane resulted in considerable root coverage and increased gingival thickness. Periodontal regeneration can be facilitated by the distinctive features of the chorion membrane. Coronally advanced flap plus chorion membrane is a novel approach for root coverage procedures.
Renin-Angiotensin-Aldosterone System (RAS) Inhibitors May Suppress the Prevalence of Peripheral Arterial Disease (PAD) in Elderly, Chronic Hemodialysis Patients

According to the hypertension guidelines, calcium antagonists are recommended as antihypertensive drugs for Stage 5 of chronic kidney disease (CKDG5) and late elderly patients, whereas renin-angiotensin-aldosterone system (RAS) inhibitors (RASi) are not recommended. We screened elderly CKDG5D patients at a single outpatient maintenance hemodialysis center for the progression of peripheral arterial disease (PAD) using the ankle-brachial index (ABI) and skin perfusion pressure (SPP) tests, as well as logistic regression analysis, to determine the association between PAD and the treatment with RASi and the association between the treatment with RASi and the need for hospitalization within one year of observation. With the presence of PAD as the explanatory variable and the presence of RASi as the objective variable, the odds ratio was 1.23 (95% confidence interval [CI] 0.37 to 3.82) in univariate analysis. After adjusting for confounding factors (age, gender, and hypertension), the odds ratio in multivariate analysis was 0.83 (95% CI 0.46 to 6.08). The presence or absence of PAD was significantly associated with an odds ratio of 3.24 (p = .04, 95% CI 1.0 to 10.25) and 4.63 (p = .026, 95% CI 1.20 to 17.84) in univariate and multivariate analyses, respectively, when the outcome was hospitalization at one year, regardless of the presence or absence of RASi. However, in univariate analysis, the odds ratio was 1.23 (95% CI 0.37 to 3.82) with RASi status as the explanatory variable and one-year hospitalization as the objective variable. After adjusting for confounders, the odds ratio in multivariate analysis was 0.83 (95% CI 0.46 to 6.08). Although further large-scale, multicenter studies are needed to establish the evidence, our results suggest that RASi treatment may have a suppressive effect on the prevalence of PAD and the need for hospitalization in elderly CKDG5 dialysis (CKDG5D) patients.
The Pattern Recognition Receptor FLS2 Can Shape the Arabidopsis Rhizosphere Microbiome β-Diversity but Not EFR1 and CERK1

Pathogen associated molecular pattern (PAMP) triggered immunity (PTI) is the first line of plant defense. We hypothesized that the absence of pattern recognition receptors (PRRs) in plants could influence the rhizosphere microbiome. Here, we report sequencing of the 16S ribosomal RNA gene and the fungal ribosomal RNA internal transcribed spacer region of rhizosphere DNA from three Arabidopsis PRR mutants involved in plant innate immunity (efr1, fls2, and cerk1). We conducted experiments in a growth chamber using native soil from the Red River Farm (Terral, OK, USA) to detect microbial community shifts in the rhizosphere that may occur in the absence of PRR receptors compared to wild-type (WT; Col-0) plants. No difference in the α-diversity of the rhizosphere microbial population was observed between the PRR mutants tested and the WT. Plant host genotype had a significant impact in bacterial β-diversity only between the fls2 mutant and the WT. Surprisingly, no significant changes in fungal β-diversity were observed between the PRR mutants and WT, although we observed an increase in relative abundance for the cup fungi (Pezizaceae) in the cerk1 mutant. This finding suggests that the FLS2 receptor can modulate the rhizosphere-associated microbiome β-diversity and expands the list of current known genotypes that can modulate the rhizosphere microbiota.
So many brackets! An analysis of how SQL learners (mis)manage complexity during query formulation

The Structured Query Language (SQL) is a widely taught database query language in computer science, data science, and software engineering programs. While highly expressive, SQL is challenging to learn for novices. Various research has explored the errors and mistakes that SQL users make. Specific attributes of SQL code, such as the number of tables and the degree of nesting, have been found to impact its understandability and maintainability. Furthermore, prior studies have shown that novices have significant issues using SQL correctly, due to factors such as expressive ease, existing knowledge and misconceptions, and the impact of cognitive load. In this paper we identify another factor: self-inflicted query complexity, where users hinder their own problem solving process. We analyse 8K intermediate and final student attempts to six SQL exer-cises, approaching complexity from four perspective: correctness, execution order, edit distance and query intricacy. Through our analyses, we find that our students are hindered in their query formulation process by mismanaging complexity through writing overly elaborate queries containing unnecessary elements, overusing brackets and nesting, and incrementally building queries with persistent errors.
