Analysis and prediction of power distribution network loss based on machine learning
Authors: Liu Jie , Cao Yijia , Li Yong , Guo Yixiu , Deng Wei 
Published: September 2022

AbstractIn this paper, the historical network loss is calculated by using the cleaned historical data collected by the user electricity meter, the transformer gateway meter every 15 min and the gateway meter of the transformer substation every half an hour. Use machine learning technologies to analyze the loss of distribution network, reveal the changing law of distribution network loss and its influencing factors (electrical/non‐electrical parameters), and predict future distribution network loss. Pearson correlation, characteristics of the Random Forest important attributes and MIC (Maximal Information Coefficient) are adopted to analyze correlations between the power network loss and the electrical parameters such as unbalanced three‐phase, power factor, load rate, active power, reactive power together with atmospheric factors (temperature, humidity, and wind speed). The factors strongly related to network loss as the input of the multi‐parallel input multi‐step output stacking LSTM (Long Term Memory) prediction model to predict network loss. The simulation data in this paper comes from the actual data of 44 subareas of the 10 KV distribution network. The experimental results show that the data cleaning methods: the cluster‐based Local Outlier Factor algorithm and the improved Random Forest imputation algorithm are effective for enhancing the prediction accuracy. Especially the improved Random Forest algorithm is robust to all missing forms. Compared with the baseline model, the multi‐parallel input multi‐step output stacking LSTM prediction model has higher forecasting accuracy.

Adaptive control for reliable cooperative intersection crossing of connected autonomous vehicles
Authors: Wei Yu , He Xiaozheng (Sean) 
Published: September 2022

AbstractRapid advances in vehicle automation and communication technologies enable connected autonomous vehicles (CAVs) to cross intersections cooperatively, which could significantly improve traffic throughput and safety at intersections. Virtual platooning, designed upon car‐following behavior, is one of the promising control methods to promote cooperative intersection crossing of CAVs. Nevertheless, demand variation raises safety and stability concerns when CAVs adopt a virtual platooning control approach. Along this line, this study proposes an adaptive vehicle control method to facilitate the formation of a virtual platoon and the cooperative crossing of CAVs, factoring demand variations at an isolated intersection. This study derives the stability conditions of virtual CAV platoons depending on the time‐varying traffic demand. Based on the derived stability conditions, an optimization model is proposed to adaptively control CAVs dynamics by balancing approaching traffic mobility and safety to enhance the reliability of cooperative crossing at intersections. The simulation results show that, compared to the nonadaptive control, our proposed method can increase the intersection throughput by 18.2%. Also, time‐to‐collision results highlight the advantages of the proposed adaptive control in securing traffic safety.

Published: September 2022

AbstractThe sand‐filled nodular pile (SFNP) foundation is newly proposed to improve the bearing capacity and accelerate consolidation settlement of foundations installed in soft clay soil. By filling sand while driving the nodular pile into the soft clay soil, the SFNP foundation provides an extra drainage path with the aid of the nodular segment, while maintaining the high modulus reinforcement body at the core of the composite foundation. The performance of the SFNP foundation is greatly influenced by its consolidation behaviour. This study develops a generalized model for the SFNP foundation, and a closed‐form solution is then established considering the smear and well resistance effects. The developed model and the associated analytical solution are employed to investigate the consolidation rate and load distribution of the SFNP foundation. Finally, the analytical solution is utilized to evaluate the performance of SFNP foundation for an expressway project located in Zhejiang, China. The predicted dissipation of the excess pore water pressure employing the developed analytical solution agreed well with measured response from the field test, which further confirmed the advantages of the SFNP foundation and the reliability of the developed solution.
An error analysis of the finite element method of the Stokes equations with parameter based on the singular function expansion
Authors: Choi Hyung Jun 
Published: September 2022

AbstractIn this paper, we introduce a mixed finite element method of the Stokes system with parameter on a non‐convex polygon. This model problem is considered in the time‐discretization of the unstationary Stokes equations, and it is mentioned in Kweon's study that the velocity field and the pressure function are composed of singular parts and smoother remainders due to the corner singularities of the solution near each re‐entrant corner. We propose a stable numerical scheme to approximate the coefficients in singular part and the regular part of solution, based on the extraction formulae of the coefficients in singular part. Furthermore, to show the reliability of the proposed method, we derive the absolute error estimates of the approximations of coefficients, and the and error estimates of the finite element solution corresponding to the regular part.
In the quest of Hückel–Hückel and Hückel–Baird double aromatic tropylium (tri)cation and anion derivatives

AbstractBesides the most common form of aromaticity involving a π‐ring, hexaiodobenzene and hexakis(phenylselenyl)benzene dications also present σ‐aromaticity in the outer ring formed by the main group substituents. These two compounds are considered σ‐ and π‐double aromatic, and their characterization is of special interest to the fields of organic and structural chemistry. In this work, we decided to explore the double aromaticity in substituted tropylium cations for three reasons: (i) the seven neutral halogen substituents of the tropylium cations will, without oxidation, lead to 14 σ‐electrons (a 4n + 2 Hückel number); (ii) tropylium cations are highly stable and can be easily generated experimentally; and (iii) whereas in substituted benzenes the distances between substituents in the optimized structures or X‐ray crystals are too large to allow strong σ‐aromaticity, these distances are expected to be shorter in substituted tropylium cations. Yet, instead of the expected σ‐aromaticity, we found that the most stable geometries are highly puckered, meaning that delocalization in both π‐ and σ‐systems is lost. Our results, which include also the tropylium anion and trication in the singlet and triplet state, show that there is a need to open a lone pair hole by oxidation to generate σ‐aromaticity. Among the systems studied, only triplet C7Br7+3 with an internal Hückel aromatic tropylium ring and an external incipient Baird aromatic Br7 ring shows double π‐ and σ‐aromaticity. This result, however, is functional‐dependent and reveals that 3C7Br73+ is at the borderline for onset of double aromaticity.

AbstractD3/D2 sub‐specificity is a complex problem to solve. Indeed, in the absence of easy structural biology of the G‐protein coupled receptors, and despite key progresses in this area, the systematic knowledge of the ligand/receptor relationship is difficult to obtain. Due to these structural biology limitations concerning membrane proteins, we favored the use of directed mutagenesis to document a rational towards the discovery of markedly specific D3 ligands over D2 ligands together with basic binding experiments. Using our methodology of stable expression of receptors in HEK cells, we constructed the gene encoding for 24 mutants and 4 chimeras of either D2 or D3 receptors and expressed them stably. Those cell lines, expressing a single copy of one receptor mutant each, were stably constructed, selected, amplified and the membranes from them were prepared. Binding data at those receptors were obtained using standard binding conditions for D2 and D3 dopamine receptors. We generated 26 new molecules derived from D2 or D3 ligands. Using 8 reference compounds and those 26 molecules, we characterized their binding at those mutants and chimeras, exemplifying an approach to better understand the difference at the molecular level of the D2 and D3 receptors. Although all the individual results are presented and could be used for minute analyses, the present report does not discuss the differences between D2 and D3 data. It simply shows the feasibility of the approach and its potential.

Published: September 2022

AbstractOne of the solutions of the Einstein equations, called McVittie solution, signifying a black hole embedded by the dynamic spacetime is studied. In the stationary spacetime the Mcvittie metric becomes the Schwarzschild‐de Sitter metric (SdS). The geodesic of a freely falling test particle towards the black hole is examined in the SdS spacetime. It is found that unlike the Schwarzschild case the potential of such particle becomes maximum at a point where it eventually stops for a while and then resumes its motion towards the center of the black hole. It is shown that an observer or system of particles is spaghettified near the black hole singularity in the SdS spacetime. The dynamics of the universe in the framework of McVittie metric, being a generalized time dependent SdS solution, is represented in terms of that point, called stationary or turning point. The motion of the stationary point is studied in various regimes of the expanding universe and the possible outcomes are discussed in brief.

AbstractAcrylamide (ACR), organic compound, has been widely used owing to its broad spectrum of chemical and industrial applications. This study aims at evaluating the response of the antioxidant defense system, fatty acid composition and histopathological aspect in the respiratory trees of Holothuria forskali against ACR exposure under laboratory conditions. Holothuries were exposed to 5, 10, and 20 mg L−1 ACR concentrations for 5 days. A significant increase in n‐6 polyunsaturated fatty acids levels especially the arachidonic acid (ARA, C20:4n‐6) and its precursor linoleic acid (LA, C18:2n‐6) in ACR‐treated organisms. Regarding the n‐3 levels, eicosapentaenoic acid (EPA, C20:5n‐3) levels were increased in treated groups despite an acute decrease in docosahexaenoic acid (DHA, C22:6n‐3) levels was observed. Our results showed a significant increase in hydrogen peroxide, malondialdehyde, protein carbonyl, and metallothionein levels along with an alteration of the antioxidants status in all treated sea cucumbers. The exposure to ACR prompted the inhibition of Acetylcholinesterase activity in a concentration‐dependent manner. The histopathological aspect was marked especially with the infiltration of coelomic cells which confirms our biochemical findings. Our study provided novel insights to create a link between redox status and fatty acid composition disruptions to better understand ACR‐triggered toxicity.

AbstractVancouver Island marmots (Marmota vancouverensis) (VIMs) are a critically endangered species of fat‐storing hibernators, endemic to Vancouver Island, British Columbia, Canada. In addition to in‐situ conservation efforts, a captive breeding program has been ongoing since 1997. The captive diet is mostly pellet‐based and rich in n−6 polyunsaturated fatty acids (PUFAs). In captivity, overall length of hibernation is shortened, and marmots have higher adipose tissue reserves compared to their wild‐born counterparts, which may be a risk factor for cardiovascular disease, the leading cause of mortality in captive marmots. To investigate differences in lipid metabolism between wild and captive populations of VIMs, blood vitamin E, fatty acid (FA) profiles and leptin, and white adipose tissue (WAT) FA profiles were compared during the active season (May to September 2019). Gas chromatography, high‐performance liquid chromatography, and multiplex kits were used to obtain FA profiles, α‐tocopherol, and leptin values, respectively. In both plasma and WAT, the concentration of the sum of all FA in the total lipids was significantly increased in captive VIMs. The n−6/n−3 ratio, saturated FAs, and n−6 PUFAS were higher in captive marmots, whereas n−3 PUFAs and the HUFA score were higher in wild marmots. Serum concentrations of α‐tocopherol were greater by an average of 45% in captive marmots, whereas leptin concentrations did not differ. Results from this study may be applied to improve the diet and implement weight management to possibly enhance the quality of hibernation and decrease the risk of cardiovascular and metabolic diseases of captive VIMs.

Published: September 2022

AbstractConducting experimental studies in learning technology and CCI research entails an iterative process of observation, rationalization, and validation. Although data collection and data analysis procedures may vary widely in complexity, their selection is based on the research objectives, RQs or hypotheses. So the researchers need to carefully select them and make sure that the research design decisions of data collection and analysis, are adequate for the goals of the study. This chapter provides information on the various data collections and analyses that are usually employed in learning technology and CCI research. This chapter is intended to serve as a guide for CCI and learning technology researchers, and help them deciding what data they need to collect and how they should analyze them to address the goals of their study.

Published: September 2022

Abstract
We investigate for viable models of inflation that can successfully produce dark matter (DM) from inflaton decay process, satisfying all the constraints from Cosmic Microwave Background (CMB) and from some other observations. In particular, we analyze near-inflection-point small field inflationary scenario with non-thermal production of fermionic DM from the decaying inflaton field during the reheating era. To this end, we propose two different models of inflation with polynomial potential. The potential of Model I contains terms proportional to linear, quadratic, and quartic in inflaton; whereas in Model II, the potential contains only even power of inflaton and the highest term is sextic in inflaton. For both the models, we find out possible constraints on the model parameters which lead to proper inflationary parameters from CMB data with a very small tensor-to-scalar ratio, as expected from a small-field model. With the allowed parameter space from CMB, we then search for satisfactory relic abundance for DM, that can be produced from inflaton via reheating, to match with the present-day cold dark matter (CDM) relic density for the parameter spaces of the DM χ mass and Yukawa couplings in the range 10−9 ≳ yχ ≳ 10−15 and 103GeV ≲ mχ ≲ 109GeV. The DM relic is associated with the inflection-points in each model via maximum temperature reached in the early universe during its production. Finally, we find out allowed parameter space coming out of combined constraints from stability analysis for both SM Higgs and DM decays from inflaton as well as from BBN and Lyman-α bounds.
Smart cities: reviewing the debate about their ethical implications

Published: September 2022

AbstractThis paper considers a host of definitions and labels attached to the concept of smart cities to identify four dimensions that ground a review of ethical concerns emerging from the current debate. These are: (1) network infrastructure, with the corresponding concerns of control, surveillance, and data privacy and ownership; (2) post-political governance, embodied in the tensions between public and private decision-making and cities as post-political entities; (3) social inclusion, expressed in the aspects of citizen participation and inclusion, and inequality and discrimination; and (4) sustainability, with a specific focus on the environment as an element to protect but also as a strategic element for the future. Given the persisting disagreements around the definition of a smart city, the article identifies in these four dimensions a more stable reference framework within which ethical concerns can be clustered and discussed. Identifying these dimensions makes possible a review of the ethical implications of smart cities that is transversal to their different types and resilient towards the unsettled debate over their definition.

Abstract
Purpose
The current study aims to report the radiologic and clinical appearance of a rare anatomical variation of the knee medial synovial plica along with its response to conservative and surgical treatment.

Case presentation
This report portrays a 29-year-old male patient with anteromedial gradual onset right knee pain, aggravated when descending stairs or prolonged sitting. Physical examination revealed medial parapatellar local tenderness, a palpable click in this area when the knee was extended, and hamstring tightness. Magnetic resonance imaging showed a duplicated medial plica, characterized by a high-intensity signal of the infrapatellar fat pad medial portion, after which a presumptive diagnosis of medial plica syndrome was proposed. After conservative treatment failure, the patient underwent standard knee arthroscopy that revealed a superior low profile and an inferior high profile medial plica, and hypertrophy of the medial portion of the infrapatellar fat pad. Both plicae and fat pad were resected with a mechanical shaver until no contact between the femoral trochlea and the fat pad was observed during full range of motion. At 4 weeks postoperatively, symptoms completely resolved, and the patient was allowed to return to full activity with no recurrences at 1 year follow-up.

Conclusions
The current study presented a rare anatomical variation of the knee medial synovial plica that was symptomatic and recalcitrant to conservative treatment. This case report may be useful for radiologists and orthopaedic surgeons to differentiate this special plica type and consider its response to conservative and surgical treatment during patient management.
