Distribution System Reliability, Voltage Profile, and Power Losses Affected by EVCS Deployment

Electric vehicles are anticipated to play a vital role in transportation in the future because of their dependability and lower CO2 and greenhouse gas emissions. However, the advancements in battery technology, combined with rising concerns about environmental pollution, have prompted the electrification of transportation. Electric vehicles (EVs), which take the place of internal combustion engine-driven vehicles, have a negative impact on power system operating parameters. The high charging load of fast EV charging stations degrades the power systems utilizing the parameters. Customer dissatisfaction will result from the degradation of the reliability of the distribution network’s critical operating parameters. The research aims to quantify and investigate the deployment effects on the voltage profile, reliability, and power losses of EVCS load of standard IEEE 33 bus Radial Distribution test system using the MATLAB programming interface.

Ab Initio Study of Tunable Electronic Properties of Monolayer Mo1-xWxS2 Alloys

When ternary compounds are created by alloying two lattice-matched nanostructures of different band gaps, such as MoS2 and WS2, the resulting compounds exhibit intriguing variations in optoelectronic properties. Here, we conducted first-principles calculations based on density-functional theory (DFT) to determine the electronic band structures and tunable physical properties of 2D randomly alloyed monolayer Mo1-xWxS2. The variation in the geometrical shape, band structure, contribution from atomic orbitals, Bader charge analysis, the density of states, energetic stability and HOMO-LUMO charge densities for different alloy compositions were assessed. Our investigation reveals that Vegard’s law for band gap deviated as W(x) composition increased, and band gap bowing parameters were determined. Moreover, electronic device parameters such as mobility, effective mass and charge accumulation were calculated, and they can be gradually tuned by varying the composition. The findings of this work revealed the tunability of the physical properties of Mo1-xWxS2 by alloying and will be beneficial to design nanoscale electronic and optoelectronic devices with enhanced performance.
An efficient edge‐based level set finite element method for free surface flow problems

We present an efficient technique for the solution of free surface flow problems using level set and a parallel edge‐based finite element method. An unstructured semi‐explicit solution scheme is proposed. A custom data structure, obtained by blending node‐based and edge‐based approaches is presented so to allow a good parallel performance. In addition to standard velocity extrapolation (for the convection of the level set function), an explicit extrapolation of the pressure field is performed in order to impose both the pressure boundary condition and the volume conservation. The latter is also improved with a modification of the divergence free constrain. The method is shown to allow an efficient solution of both simple benchmark cases and complex industrial examples.

SDNS: Artificial Neural Network Scheme to Solve the Nonlinear Skin Disease Model

In the area of medical diagnosis, there has been a need for accurate anomaly detection and disease classification. Data-driven diagnosis is necessary since skin disorders tend to take many different forms, there aren't enough skilled dermatologists, and they're scattered inaccurately. It is important to diagnose and treat skin diseases promptly, but some conditions may not present symptoms right away, which can complicate treatment for certain patients. The patients are also concerned about the treatment and diagnosis. This makes patients a lot harder to reach out to doctors in-order for diagnosis thus an automation is required which gives the results based upon pictures taken personally.
Red giants in open clusters - XIII. Orbital elements of 156 spectroscopic binaries

Context. The identification and characterisation of spectroscopic binaries with red-giant primaries in open clusters is important for a proper understanding of the colour-magnitude diagrams of the clusters. Moreover, the orbital eccentricities and axial rotations of these binaries are valuable probes into the inner structure and tidal interaction of the stars. Aims. We report on a comprehensive, long-term monitoring programme aiming to improve our knowledge of such binary systems. Methods. The radial velocities of 1309 red giants in 187 open clusters in the whole sky have been monitored with the Coravel and CfA spectrometers for 20 years, with a typical accuracy of 0.4 km s −1 per observation. Results. In total, 289 spectroscopic binaries were detected in the sample. We present first orbits for 67 systems and improved elements for another 64 previously published orbits, based on additional observations. For completeness, 25 published orbits are listed as well. The orbits are based on a total of 4039 observations, an average of 26 per system. Orbital periods range from 41.5 to 14 722 days (40 yrs), eccentricities from 0.00 to 0.81. The remaining 133 systems have too long periods, too few observations, and/or inadequate phase coverage for an orbit determination at this time. Conclusions. This paper provides a dramatic increase in the body of homogeneous orbital data available for red-giant spectroscopic binaries in open clusters. It will form the basis for a comprehensive discussion of membership, kinematics, and stellar and tidal evolution in the parent clusters.
Change of chemical and biochemical indicators of Phuc Trach pomelo in the
preservation process with chitosan-based coating with tannin and vinegar

The objective of this study was to determine the change in physicochemical and biochemical parameters of Phuc Trach pomelo during preservation by coating. From there, it forms the basis for building a preservation process. Preservative coating preparations are formed by mixing ingredients according to the ratio: 1.92% chitosan, 0.24% tannin, 1.92% vinegar, and 95.92% water. One kg of this preparation will be enough to cover about 19 kg of pomelo. Set up four experimental formulas to preserve Phuc Trach pomelo: CT1: preserved in the natural environment, no preservative coating is used, the content of coating-forming preparations is 0%; CT2, CT3, CT4 used coatingforming preparations with the content of 1.0%, 1.5% and 2.0%, respectively. The results showed that Phuc Trach pomelo preserved in formula CT3 with the composition of 1.5% was effective in limiting the change of physico-chemical and biochemical indicators more effectively than other experimental formulas. After 7 weeks of storage, the colour changed from 0.96 to 8.16, hardness changed from 15.16 to 10.23 (kg/cm2 ); respiratory intensity from 35.68 to 18.95 (mL CO2/kg.h); soluble solids content from 10.04 to 11.46oBx; total sugar content from 8.99 to 5.06%; vitamin C content from 0.84 to 0.42mg/g; total protein content from 0.79 to 0.38%; total organic acid content from 0.62 to 0.17%. Meanwhile, Phuc Trach pomelos preserved in other recipes until the 5th and 6th week were completely rotten. Therefore, the formula CT3 was selected with a preservative composition of 1.5% to develop the process of preserving Phuc Trach pomelo.
Continuity of Derivations in F-Algebras

In [1] Johnson considered commutative semisimple F-algebras with identity which are also Q-algebras. (A Q-algebra is an algebra in which the set of invertible elements is open.) For an algebra A of this type, Johnson proved that any derivation of A into A^, the algebra of all Gelfand transforms of elements of A, is continuous. The difficulty with this theorem is that the standard examples of F-algebras with derivations are not Q-algebras. In particular, neither the algebra CG (0, 1), nor the algebra Hol (Q), each with the standard F-algebra topology, is a Q-algebra. Here Co (0, 1) denotes the algebra of all complex valued infinitely differentiable functions on (0, 1), and Hol (Q) is the algebra of all functions which are holomorphic on an open subset Q of the complex plane. In fact, one often turns to F-algebras in order to avoid the restrictions (such as every element having a compact spectrum) placed on an algebra by requiring the algebra to be a Q-algebra. Tihe purpose of this note is to show how Johnson's techniques can be used to prove that every derivation of an F-algebra A into the algebra A is continuous, where it is only assumed that A is commutative, semisimple, and has an identity. From this fact, we can conclude that every derivation of A into A' is continuous, since any such derivation can be factored through A. In particular, we have that any derivation of a Frechet function algebra into itself is continuous. A will denote a commutative semisimple F-algebra with identity. For an element a of A, aA will denote the Gelfand transform of the element a, and A' will denote the algebra of all Gelfand transforms of elements of A. If B is an F-algebra, then we will use Spec B to denote the space of all continuous homomorphisms of B onto the complex numbers, where the space of homomorphisms is given the Gdelfand topology. We fix a sequence {Bn} of Banach algebras such that A is the inverse limit of the Banach algebras
Discussion on "Statistical Issues Arising in the Women's Health Initiative"

A brief overview of the design of the Women’s Health Initiative (WHI) clinical trial and observational study is provided along with a summary of results from the postmenopausal hormone therapy clinical trial components. Since its inception in 1992, the WHI has encountered a number of statistical issues where further methodology developments are needed. These include measurement error modeling and analysis procedures for dietary and physical activity assessment; clinical trial monitoring methods when treatments may affect multiple clinical outcomes, either beneficially or adversely; study design and analysis procedures for high-dimensional genomic and proteomic data; and failure time data analysis procedures when treatment group hazard ratios are time dependent. This final topic seems important in resolving the discrepancy between WHI clinical trial and observational study results on postmenopausal hormone therapy and cardiovascular disease.
Global density of reducible quasi-periodic cocycles on T x SU(2)

We prove that given a in a set of total (Haar) measure in T 1 = R/Z, the set of A ∈ C ∞ (T 1 , SU(2)) for which the skew-product system (α, A): T 1 × SU(2) → T 1 × SU(2), (α, A)(θ,y) = (θ + α, A(θ)y) is reducible - that is, A(.) = B(.+ α)A 0 B(.) - 1 , for some A 0 ∈ SU(2), B ∈ C ∞ (T 1 , SU(2)),- is dense for the C°°-topology.
Dysbiosis of the Gut Microbiota and Kynurenine (Kyn) Pathway Activity as Potential Biomarkers in Patients with Major Depressive Disorder

With increasing attention paid to the concept of the microbiota–gut–brain axis, mounting evidence reveals that the gut microbiota is involved in a variety of neurological and psychiatric diseases. However, gut microbiota changes in major depressive disorder (MDD) patients and their association with disease mechanisms remain undefined. Fifty MDD patients and sixty healthy controls were recruited from the Shanghai Healthy Mental Center, China. Fecal samples were collected, and the compositional characteristics of the intestinal flora were determined in MDD patients by MiSeq sequencing. Venous blood was collected for the detection of plasma indoleamine-2,3-dioxygenase (Ido), kynurenine (Kyn) and tryptophan (Trp) levels. Stool samples of bacterial 16S sequencing was carried out. A total of 2,705,809 optimized sequences were obtained, with an average of 54,116 per sample. More unique OTUs were observed at the family, genus and species levels in the control group compared with the MDD cases. Further analysis showed significant changes in the α- and β-diversities and relative abundance levels of gut microbial entities in MDD patients, as well as elevated amounts of Ido and Kyn indicating Kyn pathway activation, KEGG bacterial 16S function prediction analysis shows a variety of amino acids and metabolic (including Ido, Trp and Kyn) changes in the body of patients with MDD. These may result in increased neurotoxic metabolites and reduced generation of serotonin in the disease process. These changed factors may potentially be utilized as biomarkers for MDD in the future, playing more important roles in the disease course.
Foundations of the Scale-Symmetric Physics (Main Article No 1: Particle Physics)

Here we showed that the non-perturbative Scale-Symmetric Theory (SST) is the lacking part of Theory of Everything (ToE). General Relativity (GR) leads to the Higgs field composed of the non-gravitating tachyons. Due to the succeeding phase transitions of the superluminal Higgs field, there appear different scales - it is the foundations of the Scale-Symmetric Theory. Theories of three scales are dual i.e. ratios of physical quantities in these scales concerning the same mechanisms, have the same values. Due to the succeeding phase transitions, there appear the binary systems of superluminal closed strings (i.e. the entanglons that are responsible for the quantum entanglement), neutrinos and neutrino-antineutrino pairs the luminal Einstein spacetime consists of, cores of baryons, and cores of cosmic structures (the cores of protoworlds) that evolution leads to dark matter, dark energy, and to the expanding universes. There appear three additional interactions i.e. viscosity of tachyons, superluminal linear quantum entanglement, and volumetric confinement. There appears the four-particle symmetry that solves many problems. Here as well we described the internal dynamics of baryons that leads to the atom-like structure of baryons and next to mesons and to the composite Higgs boson with a mass of 125 GeV. Among many other things, we described symmetries and laws of conservation that result from the initial parameters, we calculated the physical constants from initial conditions, coupling constants, running coupling for nuclear strong interactions and masses of quarks. Due to the superluminal Higgs field, the neutrinos acquire their gravitational mass. Theoretical results are much better than results obtained within Standard Model. We apply 7 parameters only and very simple mathematics.
The Effectiveness of Intraosseous Basivertebral Nerve Ablation in the Treatment of Nonradiating Vertebrogenic Pain: A Systematic Review

Intraosseous basivertebral nerve ablation has shown sustained efficacy in treating chronic axial low back pain (LBP) in patients with type 1 or 2 Modic changes. This systematic review aims to determine the efficacy of intraosseous basivertebral nerve radiofrequency ablation in treating nonradiating axial chronic LBP compared to standard therapy, sham, or without contrast. The population of interest is individuals greater than or equal to 18 years old with chronic nonradiating vertebrogenic pain. The key outcome was the percentage of patients with greater than or equal to 50% pain reduction, greater than or equal to 10-point improvement in function and disability measured by the Oswestry Disability Index (ODI), greater than or equal to two-point pain reduction in the visual analog scale (VAS) or numerical pain rating scale, and a decrease in opioid utilization by 10 morphine milligram equivalents. Three databases, PubMed, MEDLINE, and Google Scholar, were used to retrieve the studies for the review. Two independent reviewers assessed the studies for inclusion using the validated tools for quality appraisal. There were 286 articles in total; however, only 11 publications with extensive data on 413 participants matched the inclusion criteria and were used for this review. At three months, a majority of the participants reported greater than or equal to 10-point improvement in the ODI, a measure of functional and disability improvement on a 10-point scale, and greater than or equal to two-point improvement in the VAS. A good number of patients in the basivertebral nerve ablation (BVNA) arm reported complete pain resolution demonstrating therapy success and the superiority of BVNA over sham and standard treatment. Basivertebral nerve radiofrequency ablation, among other criteria, is a safe and minimally invasive therapy that significantly lowers pain and impairment in individuals with vertebrogenic pain with distinct Modic type 1 and 2 changes at lumbar vertebra three-sacral vertebra one (L3-S1) vertebral levels. Proper patient selection and exact procedural methods are essential to the success of basivertebral nerve neurotomy. The findings of the existing investigations require confirmation by nonindustry-funded, large-scale, high-quality trials using generalizable study participants.
Market orientation and performance: The interaction effect of entrepreneurial orientation

The centrality of resource-based view (RBV) from different angles and in diverse situations has widely been acknowledged, explored and researched. Keeping in view that the area still needs researchers’ attention. This study looks into the possible impact of market orientation (MO) on organizational performance. The study will also be looking at the moderating role of entrepreneurial orientation (EO) in the MO and organizational performance link among the small and medium enterprises (SMEs). This is a survey type of qualitative and questionnaire based research. Sample size of the study is 213. The results of the study reveal the presence of positive relationship among the MO and organizational performance. The results of the study also demonstrate that the effects of MO on organizational performance are positively moderated by EO behaviors. This study covers the limitation of the previous studies by utilizing EO as a five-dimensional construct. This research fills the gap by probing the association of MO with organizational performance moderated by EO in a developing economy’s context like Pakistan. This is an empirical study with a reasonable sample size and the results have both academic as well as practical implications. The study has a number of limitations like using a single informant for data collection and studying only one city. Future research directions have also been provided.
Random Genetic Drift in a Tri-Allelic Locus; Exact Solution with a Continuous Model

Random genetic drift is a stochastic process of change in gene frequency in finite populations due to random sampling of gametes in reproduction. Since the pioneerinig works by Fisher (1922, 1930) and Wright (1931), much attention has been paid to this phenomenon and many theoretical as well as experimental studies have been attempted. A brief review on this topic will be found in a previous paper (Kimura 1955b). The evolutionary significance of random drift is still in dispute (Fisher and Ford 1947, 1950; Wright 1948, 1951), and decisive evidence for any conclusion is still missing. Haldane (1954) has suggested an analysis of frequencies of antigenic characters among neighboring populations for this purpose. Recently, Glass (1954) reviewed some evidence for the operation of random drift in human populations. From the genetical point of view, it is highly probable that there exists a class of genes so nearly neutral in selective value that random genetic drift plays a prominent role in determining the local differentiation of the gene frequencies. The best examples are to be found in certain isoalleles in Drosophila and other organisms. From the standpoint of mathematical genetics, the problem of random drift provides an area where the theory of Markov processes finds important applications (Feller 1951, Crow and Kimura 1955). In a recent paper the present author reported a complete solution of the process for the case of a pair of alleles (Kimura 1955a). With multiple alleles the problem becomes more difficult, and the solution even for three alleles (Kimura 1955b) contains a function CQ (x, y) and only the first three terms in the expansion are given explicitly.

The New Brittle-Star Species Stegophiura takaisoensis (Echinodermata, Ophiuroidea) from the Pliocene of Ibaraki Prefecture, Central Japan

Abstract. We describe three well-preserved, articulated brittle stars from the Pliocene Hatsuzaki Formation, Hitachi Group of Ibaraki, central Japan, as a new species, Stegophiura takaisoensis. It differs from its congeners in having dorsal arm plates with a high ridge and large swollen disk scales. The only other previously described extinct species unambiguously assigned to Stegophiura is S. miyazakii from the Upper Cretaceous of Japan. The new species from the Pliocene significantly adds to the fossil record of the genus, representing the second extinct species known to date and filling part of the fossil record gap between the Upper Cretaceous and the Recent representatives. The specimens have the disk and arms in intact live position, without any signs of transportation before buried. We assume that they were buried alive in their original deep shelf to upper slope habitat by rapid channel fills.
Environmental assessment of hydrogen: does hydrogen matter for environmental efficiency improvement?

ABSTRACT This paper first measures the level of environmental efficiency (EE) in 72 countries between 2001 and 2019 by adopting the Global Malmquist-Luenberger productivity index in the framework of the super slack-based-measure model. Then, by using the instrument variable-generalized method of moments (IV-GMM) approach, we examine the role of hydrogen development in increasing EE. We also pay attention to the asymmetric effect, the moderating effect, and the mediating effect in the hydrogen development-EE nexus. Several findings are highlighted as follows: (1) Hydrogen development can significantly increase EE. (2) The marginal impact of hydrogen development on EE is significantly positive in countries with a high level of EE, while it is insignificant in countries with a low level of EE, which shows the asymmetric EE enhancement effect of hydrogen development. (3) Foreign direct investment is a key moderating variable in the nexus between hydrogen development and EE, which can strengthen this positive nexus. And (4) mediating effect analysis documents that technological progress is an effective mediating variable through which hydrogen development affects EE. According to these results, we propose several policy implications for the acceleration of hydrogen development and EE.
