Two‐stage self‐adaption security and low‐carbon dispatch strategy of energy storage systems in distribution networks with high proportion of photovoltaics

Published: July 2023

AbstractWith the goal of achieving carbon neutrality, active distribution networks (DNs) with a high proportion of photovoltaics (PVs) are facing challenges in maintaining voltage stability and low‐carbon operation. Energy storage systems (ESSs), which have the ability to store and transfer energy temporarily, can be used as effective measures to enhance the capacity of consuming PVs and reduce carbon emissions in DNs. However, existing low‐carbon dispatch strategies for multiple sources, storages and loads fail to consider voltage violations, while the temporal carbon emission intensity of the upper‐level power grid is also often overlooked, which is an important factor that affects the dispatch strategy. Therefore, a two‐stage self‐adaptive dispatch strategy of ESSs that considers the temporal characteristics of slack nodal carbon emission intensity to minimise carbon emissions while maintaining voltage stability in DNs with high access to PVs is proposed. First, the framework of the proposed two‐stage self‐adaptive dispatch strategy of ESSs is established by taking into account the effects of ESSs on adjusting voltages and reducing carbon emissions, respectively, with the two‐stage switch principle of two operation modes being determined. On this basis, an optimization dispatch model is established to improve voltages and carbon emissions, and the optimal day‐ahead dispatch strategy of ESSs can be obtained by solving the model using genetic algorithm. Case studies of the modified 10 kV IEEE 33‐node DN and IEEE 123‐node DN verify the feasibility and superiority of the proposed two‐stage self‐adaptive security and low‐carbon day‐ahead dispatch strategy for ESSs, showing that the voltage stabilisation and lower carbon emissions of DNs are both improved.

Le suivi de la mémoire des attentats du 13 novembre, et plus généralement des attaques terroristes depuis l’an 2000, auprès de la population générale offre un matériau inédit pour comprendre l’évolution dans le temps et la construction de la mémoire collective. L’étude montre que ces attaques ont davantage marqué la population que d’autres événements tragiques survenus dans l’Hexagone dans une période de temps proche, ou même que d’autres attentats beaucoup plus récents. Avec le temps, la mémorisation précise des faits et les souvenirs des circonstances dans lesquelles les personnes ont appris les faits s’érodent, et se concentrent notamment autour du lieu du Bataclan. Mais, cette imprécision fait place à un investissement symbolique plus fort, qui conduit notamment à une surestimation du nombre de terroristes ou de victimes. Les raisons de la place particulière dévolue aux attaques du 13 novembre dans la mémoire collective tiennent à la fois au nombre inégalé de victimes, à l’attaque de lieux situés dans la capitale, à la réaction des pouvoirs publics qui instaurent l’état d’urgence, au cadrage discursif de la guerre contre le terrorisme amplifié par les médias télévisuels et au sentiment que la menace islamiste peut tuer aveuglément sans viser des catégories précises de population. L’étude met également à jour l’influence des systèmes de valeur (couleur politique, regard sur le modèle républicain) et des caractéristiques sociales des individus sur la mémoire. Elle s’inscrit dans une recherche fondamentalement pluridisciplinaire autour de la « Mémoire et traumatisme » intégrant des travaux en biologie, neurosciences et médecine.
Mémoire collective et mémoire sociale : apports de la sociologie à une théorie générale de la mémoire
Authors: Orianne Jean-François 
Published: July 2023

Une théorie générale de la mémoire est-elle possible ? Quelle contribution la sociologie peut-elle apporter à ce vaste projet scientifique ? Deux contributions originales sont présentées et discutées dans cet article : (1) le concept de mémoire collective (Maurice Halbwachs) ; (2) le concept de mémoire sociale (Niklas Luhmann). L’auteur propose quelques clarifications théoriques importantes. D’abord, la mémoire n’est ni un stock ni une collection (d’états ou d’événements passés) mais plutôt une opération continue de tri entre souvenir et oubli. Ensuite, la mémoire collective n’est pas la mémoire sociale : en effet, la première est une opération spécifique des systèmes psychiques ; quant à la seconde, elle est une opération de communication, propre aux systèmes sociaux. Dans le cas particulier des attentats du 13 novembre 2015 à Paris, l’auteur montre la fonction de mémoire sociale que remplit le système des médias de masse et comment ces opérations de filtrage du sens conditionnent la construction de souvenirs traumatiques.

Abstract
Clausena excavata is a medicinal plant widely distributed in Southeast Asia. It is used for a variety of indications, including to treat malaria. In our present study, a
phytochemical study of the methanol extract from the stem bark of C. excavata led to the isolation of five pyranocoumarins, nordentatin (1), dentatin (2), kinocoumarin
(3), clausarin (4), and clausenidin (5), and a coumarin, 8-hydroxy-3″,4″-dihydrocapnolactone-2′,3′-diol (6). The isolation of compound 6 from C.
excavata and the antiplasmodial activities against a multidrug-resistant K1 strain of Plasmodium falciparum of 1, 3, and 5 were reported for the first time.
Compounds 3 and 4 exhibited potent antiplasmodial activities with EC50 values of 1.10 and 0.58 µM, respectively, while 1 and 5 had EC50
values of 5.62 and 7.15 µM, respectively. A prenyl group attached to the C-3 or C-12 position on the pyranocoumarin ring probably plays an important role on the activity. A hydroxyl group at
the C-10 position is also likely to enhance the activity.
Decoration on Cubane with an Awareness of Chirality: Development of Substituted Cubane Syntheses
Authors: Matsubara Seijiro , Takebe Hiyori 
Published: July 2023

AbstractNearly 60 years have passed since Professor Eaton’s practical synthesis of cubane, and research using it as a unique molecular scaffold has since gained momentum. Since the early synthesis of polynitrocubane, it has been shown that up to eight substituents can be covalently assembled into a confined space. The arrangement of substituents on cubane has paved the way for the creation of unique asymmetric molecules. To put it another way, chirality is manifested by selectively introducing three or more diverse types of substituents at specific sites. Recently, there has also been a report on the synthesis of perfluorocubane, a molecule with intriguing electronic properties.1	Introduction2	General Information3	Functionalization of Cubane4	Preparation of Polysubstituted Cubanes5	Conclusion

Published: July 2023

AbstractThe palladium-catalyzed homo-dimerization of terminal alkynes is a powerful and atom-economic method for the preparation of highly unsaturated four-carbon skeletons, which are key structural units found in natural and/or biologically active products and materials. However, during the homo-dimerization of terminal alkynes, a major issue is control of the chemo-, regio-, and stereoselectivity. Thus, over the past few decades, various strategies and methods have been developed that employ palladium catalytic systems for such homo-dimerizations. In this Short Review, we highlight important methods for the selective synthesis of these valuable four-carbon compounds, including conjugated 1,3-enynes, 1,3-diynes, and 1,3-dienes.1	Introduction2	Redox-Neutral Homo-Dimerization of Terminal Alkynes for the Synthesis of 1,3-Enynes2.1	Head-to-Head Dimerization2.2	Head-to-Tail Dimerization3	Oxidative Homo-Dimerization of Terminal Alkynes for the Synthesis of 1,3-Diynes3.1	Unsupported Palladium Catalysts3.1.1	Choice of Oxidant3.1.2	Choice of Ligand3.1.3	Choice of Solvent3.2	Supported Palladium Catalysts4	Reductive Homo-Dimerization of Terminal Alkynes for the Synthesis of 1,3-Dienes5	Conclusion

AbstractFor developing general synthetic access toward dimeric pyranonaphthoquinones including β-naphthocyclinone, actinorhodin, and γ-actinorhodin, we report stereodefined 6,9,10-trioxypyranonaphthalene as a versatile intermediate. Its robust preparation started from ethyl (S)-4-chloro-3-hydroxybutyrate. The pyranonaphthalene core was constructed by a Michael–Dieckmann sequence, and methylation using Me3Al and BF3·OEt2 established the required trans structure in a scalable manner. Conversion of this intermediate into ent-hemi-actinorhodin and into ent-hemi-γ-actinorhodin are also reported, in which the conditions for the oxidative lactonization were optimized.

Abstract
Objective Sleep disorders are disabling and highly prevalent comorbidities in Parkinson's disease (PD). This study's objective was to verify the effectiveness of neurofunctional physiotherapy in sleep quality, objectively and subjectively assessing it among individuals with PD.
Methods A sample of individuals with PD was assessed before and after 32 physiotherapy sessions and three months later (follow-up). The following instruments were used: Pittsburgh Sleep Quality Index (PSQI); Epworth Sleepiness Scale (ESS); Parkinson's Disease Sleep Scale (PDSS), and actigraphy.
Results Nineteen individuals aged 67.37 years old ( ±  8.03) on average were included. No differences were found in any of the variables measured by the actigraphy or the ESS. Improvement was found from pre- to post-intervention in terms of nocturnal movements (p = 0.04; d = 0.46) and total score (p = 0.03; d = 0.53) obtained on the PDSS. Improvement was also found in the PDSS sleep onset/maintenance domain (p = 0.001; d = 0.75) between pre-intervention and follow-up. The participants' total score obtained in the PSQI improved from pre- to post-intervention (p = 0.03; d = 0.44). Significant differences were found in nighttime sleep (p = 0.02; d = 0.51) and nocturnal movements (p = 0.02; d = 0.55), and in the PDSS total score (p = 0.04; d = 0.63) between pre- and post-intervention when only the poor sleepers subgroup (n = 13) was considered, while improvements were found in sleep onset/maintenance (p = 0.003; d = 0.91) between pre-intervention and follow-up.
Discussion Neurofunctional physiotherapy was ineffective in improving objective parameters of sleep but was effective in improving the perception of sleep quality subjectively assessed among individuals with PD, especially those who perceived themselves to be poor sleepers.
Investigating the factors affecting ICT integration of in-service teachers in Henan Province, China: structural equation modeling
Authors: Peng Ran , Razak Rafiza Abdul , Halili Siti Hajar 
Published: July 2023

AbstractThe integration of Information and Communication Technology (ICT) can significantly improve teaching and learning outcomes, but various factors determine the degree to which ICT is integrated into educational practices. This study used quantitative methodology to examine four key factors that impact in-service teachers’ ICT integration and how they interact with each other. Data was collected through snowball sampling from 685 in-service teachers in Henan Province, China. Using partial least squares structural equation modeling (PLS-SEM), the study analyzed four factors from the Technology Acceptance Model 3 (TAM 3) and the Will-Skill-Tool model (WST model): attitudes (AT), self-efficacy (SE), digital competence (DC), and digital tools utilization (DTU). The findings revealed that all four elements exerted a noteworthy influence on the integration of ICT by in-service instructors. Meanwhile, attitudes, digital competence, and digital tools utilization have a mediating effect in this research. Additionally, the study examined how gender, age, and teaching experience influence these factors and ICT integration. The findings revealed that females exhibit higher levels of positive attitudes and digital competence than males, while teachers aged 31–35 years have stronger digital abilities, digital tool use, and ICT integration compared to younger or older teachers. Furthermore, teachers with less than three years of teaching experience exhibit significantly stronger attitudes, self-efficacy, digital competence, and ICT integration than those with more than ten years of experience. The implication of the study provides valuable insights for designing effective ICT-based instruction and developing teacher education and educational technology programs aimed at promoting ICT integration in the classroom.

Published: July 2023

Abstract
The advancement of gas sensors with ppb level concentration experiences profound challenges. In this research, Lanthanum (La)-Zinc Oxide (ZnO)/multi-walled carbon nanotubes (MWCNTs) composites were successfully fabricated and loaded on a flexible polyimide substrate where interdigitated electrodes (thickness: 300 µm and spacing: 300 µm) were prepared using a laser carbonation technique for room temperature (RT) carbon monoxide (CO) gas detection. The synthesized composites were characterized using scanning electron microscopy, energy dispersive x-ray spectroscopy, UV–visible spectrophotometry, x-ray diffraction, and Fourier transform infrared spectroscopy. When compared to the La-ZnO composite, the addition of MWCNTs on the synthesized composite-based sensor exhibited ∼8 times higher response than La-ZnO to 100 ppm CO at 27 °C. The response of the La-ZnO/MWCNTs composite sensors to 20 ppm CO was tested at six different relative humidity (RH) levels ranging from 0% to 90% in the increments of 20% RH. These sensors exhibited humidity tolerant properties, as evidenced by their responses to different humidity levels. Even when exposed to 90% RH, the sensor only showed ∼13% reduction in response compared to 0% RH, indicating that it is a humidity tolerant sensor. Furthermore, the La-ZnO/MWCNTs sensor has excellent selectivity and can detect low CO concentrations of 100 ppb. As a result, the proposed high-performance flexible sensor has a lot of potential for use in wearable devices to sense CO gas at RT for trace level detection.
Shear flexoelectricity of alcoholic liquids with low viscosity
Authors: Zhang Shuwen , Ji Hui , Liu Kaiyuan , Li Yifan , Xu Minglong 
Published: July 2023

Abstract
Flexoelectricity in solid dielectric materials has been researched and adopted in applications due to its advantages of size dependence, non-limitation of temperature, and wide range of material selection and mechanical designs. Flexoelectricity in dielectric liquids is also important due to its advantages, but few researches have been applied due to the absence of theoretical and experimental methods. In this study, a series of alcoholic liquids with low viscosity values are theoretically predicted and experimentally verified, which are manipulated by the relative permittivity, initial dipole moment density, value and length of liquids. This study reveals a micro-scale electromechanical procedure for shear flexoelectricity in liquid alcohols and helps in predicting the flexoelectric response of dielectric liquids with low viscosity.
Local measures of fluctuations in inhomogeneous liquids: statistical mechanics and illustrative applications
Authors: Eckert Tobias , Stuhlmüller Nico C X , Sammüller Florian , Schmidt Matthias 
Published: July 2023

Abstract
We show in detail how three one-body fluctuation profiles, namely the local compressibility, the local thermal susceptibility, and the reduced density, can be obtained from a statistical mechanical many-body description of classical particle-based systems. We present several different and equivalent routes to the definition of each fluctuation profile, facilitating their explicit numerical calculation in inhomogeneous equilibrium systems. This underlying framework is used for the derivation of further properties such as hard wall contact theorems and novel types of inhomogeneous one-body Ornstein–Zernike equations. The practical accessibility of all three fluctuation profiles is exemplified by grand canonical Monte Carlo simulations that we present for hard sphere, Gaussian core and Lennard–Jones fluids in confinement.

Abstract
The goal of this study is to investigate the effect of the location and width of a single lead shield on the dose rate of staff and caregivers in a hospital room with an I-131 patient. The best orientation of the patient and caregiver relative to the shield was determined based on minimizing staff and caregiver radiation dose rates. Shielded and unshielded dose rates were simulated using a Monte Carlo computer simulation and validated using real-world ionisation chamber measurements. Based on a radiation transport analysis using an adult voxel phantom published by the International Commission on Radiological Protection, placing the shield near the caregiver yielded the lowest dose rates. However, this strategy reduced the dose rate in only a tiny area of the room. Furthermore, positioning the shield near the patient in the caudal direction provided a modest dose rate reduction while shielding a large room area. Finally, increased shield width was associated with decreasing dose rates, but only a four-fold dose-rate reduction was observed for standard width shields. The recommendations of this case study may be considered as potential candidate room configurations where radiation dose rates are minimized, however these findings must be weighed against additional clinical, safety, and comfort considerations.
A coarse-grained study on mechanical behaviors of diamond-like carbon based on machine learning
Authors: Xiong Zhipeng , Yu Yifeng , Chen Huan , Bai Lichun 
Published: July 2023

Abstract
Diamond-like carbon (DLC) films have broad application potential due to their high hardness, high wear resistance, and self-lubricating properties. However, considering that DLC films are micron-scale, neither finite element methods nor macroscopic experiments can reveal their deformation and failure mechanisms. Here we propose a coarse-grained molecular dynamics (CGMD) approach which expands the capabilities of molecular dynamics simulations to uniaxial tensile behavior of DLC films at a higher scale. The Tersoff potential is modified by high-throughput screening calculations for CGMD. Given this circumstance, machine learning (ML) models are employed to reduce the high-throughput computational cost by 86%, greatly improving the efficiency of parameter optimization in second- and fourth-order CGMD. The final obtained coarse-grained tensile curves fit well with that of the all-atom curves, showing that the ML-based CGMD method can investigate DLC films at higher scales while saving a large number of computational resources, which is important for promoting the research and production of high-performance DLC films.
A study on the pesticides-loading capacity of dendritic fibrous nano silica synthesized from 1-pentanol-water microemulsion with a low oil-water ratio

Published: July 2023

Abstract
Dendritic fibrous nano silica (DFNS) represents an optimal carrier material for pesticide constituents, due to its radial accessibility channels and high specific surface area. A low-energy methodology for synthesizing DFNS at a low volume ratio of oil to water is provided by employing 1-pentanol as the oil solvent in the microemulsion synthesis system, renowned for its remarkable stability and exceptional solubility. The DFNS@KM nano-pesticide was fabricated using a diffusion supported loading (DiSupLo) method and kresoxim-methyl (KM) as the template drug. Findings from Fourier-transform infrared spectroscopy, XRD, thermogravimetric, differential thermal analysis, and Brunauer–Emmet–Teller analyzes revealed the physical adsorption of KM onto the synthesized DFNS without any chemical bonding, with KM mainly existing in an amorphous state within the channels. High-performance liquid chromatography measurements demonstrated that only the loading amount of DFNS@KM was primarily dependent on the KM to DFNS ratio, with minimal effects observed from loading temperature and time. The loading amount and encapsulation efficiency of DFNS@KM were found to be 63.09% and 84.12%, respectively. Furthermore, DFNS effectively prolonged the release of KM, with a cumulative release rate of 85.43% over 180 h. The successful loading of pesticide components into DFNS synthesized with a low oil-to-water ratio provides theoretical support for the industrialization of nano-pesticides, with significant implications for enhancing pesticide utilization, reducing pesticide dosage, augmenting agricultural efficiency, and promoting sustainable agricultural development.
