Earthquake‐resistant AAC infills: damage prevention with an innovative decoupling system
Authors: Trutalli Davide , Miccoli Lorenzo , Brandolese Sara , Scotta Roberto , Miliani Alessandro 
Published: September 2023

AbstractBackgroundRecent studies on masonry infills have shown that damages can be more serious when frame and infill are coupled. Although the discussion on out‐of‐plane (OOP) stability and strength of isolated infills is still open, the development of solutions able to assure the decoupling of infill panels respect to structural frame seems to be the most promising in terms of damage prevention of the building.AimA system for decoupling the RC frame and the aerated autoclaved concrete (AAC) masonry infill reinforced with textile reinforced mortar (TRM) is presented. The goal is to analyze the potential of this system to face the OOP actions caused by a seismic event.MethodIn this system, the frame is free to deform in its plane, without interaction with the AAC infill, which is supported by retaining brackets at the top. These brackets allow relative in‐plane displacements between the RC frame and the masonry infill and avoid OOP overturning of the infill.ResultsThe paper shows the design of the system and provides an overview of the seismic capacities validated by testing on the system components. Based on the analysis and comparison of the test results, the performance and effectiveness of the proposed system are presented.

AbstractThe design of non‐noble metal bifunctional electrocatalysts with outstanding performance and remarkable stability for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is one of the most essential issues to the realization of rechargeable zinc‐air battery, and transition metal phosphides (TMPs) have emerged as robust candidates for oxygen electrocatalysts. Herein, N‐doped carbon‐coated phosphorus‐vacancies‐rich Ni2P particles (Vp‐Ni2P@NC) is proposed via simple carbonization and following Ar plasma treatment from a single nickel phosphonate metal–organic framework (MOF) without extra phosphine and nitrogen sources. The facile and rapid plasma treatment can achieve phosphorus vacancies which could modulate the electronic structure to enhance the inherent active and electrical conductivity. Meanwhile, the pyridine‐N and graphitized‐N produced during calcination also could provide more active sites and increase the electrical conductivity. The resultant Vp‐Ni2P@NC catalyst shows excellent bifunctional electrocatalytic activity (OER/ORR) based on synergistic effect of introducing P vacancies into Ni2P and N‐doped carbon. Vp‐Ni2P@NC catalyst shows more advantageous ΔE value (0.70 V) compared to Pt/C+RuO2 (0.73 V) and most reported catalysts. Additionally, the zinc‐air bbatterie (ZAB) employing Vp‐Ni2P@NC as air cathode shows excellent performance. The maximum power density of 203.48 mW cm−2, the cycling stability of more than 150 h at 10 mA cm−2.

Hearing the shape of ancient noncollapsed flows in R4$\mathbb {R}^{4}$
Authors: Du Wenkui , Haslhofer Robert 
Published: September 2023

AbstractWe consider ancient noncollapsed mean curvature flows in whose tangent flow at is a bubble‐sheet. We carry out a fine spectral analysis for the bubble‐sheet function u that measures the deviation of the renormalized flow from the round cylinder and prove that for we have the fine asymptotics , where is a symmetric 2 × 2‐matrix whose eigenvalues are quantized to be either 0 or . This naturally breaks up the classification problem for general ancient noncollapsed flows in into three cases depending on the rank of Q. In the case , generalizing a prior result of Choi, Hershkovits and the second author, we prove that the flow is either a round shrinking cylinder or 2d‐bowl. In the case , under the additional assumption that the flow either splits off a line or is self‐similarly translating, as a consequence of recent work by Angenent, Brendle, Choi, Daskalopoulos, Hershkovits, Sesum and the second author we show that the flow must be 2d‐oval or belongs to the one‐parameter family of 3d oval‐bowls constructed by Hoffman‐Ilmanen‐Martin‐White, respectively. Finally, in the case we show that the flow is compact and SO(2)‐symmetric and for has the same sharp asymptotics as the O(2) × O(2)‐symmetric ancient ovals constructed by Hershkovits and the second author. The full classification problem will be addressed in subsequent papers based on the results of the present paper.
Existence of multi‐dimensional contact discontinuities for the ideal compressible magnetohydrodynamics
Authors: Wang Yanjin , Xin Zhouping 
Published: September 2023

AbstractWe establish the local existence and uniqueness of multi‐dimensional contact discontinuities for the ideal compressible magnetohydrodynamics (MHD) in Sobolev spaces, which are most typical interfacial waves for astrophysical plasmas and prototypical fundamental waves for hyperbolic systems of conservation laws. Such waves are characteristic discontinuities for which there is no flow across the discontinuity surface while the magnetic field crosses transversely, which lead to a two‐phase free boundary problem where the pressure, velocity and magnetic field are continuous across the interface whereas the entropy and density may have jumps. To overcome the difficulties of possible nonlinear Rayleigh–Taylor instability and loss of derivatives, here we use crucially the Lagrangian formulation and Cauchy's celebrated integral (1815) for the magnetic field. These motivate us to define two special good unknowns; one enables us to capture the boundary regularizing effect of the transversal magnetic field on the flow map, and the other one allows us to get around the troublesome boundary integrals due to the transversality of the magnetic field. In particular, our result removes the additional assumption of the Rayleigh–Taylor sign condition required by Morando, Trakhinin and Trebeschi (J. Differ. Equ. 258 (2015), no. 7, 2531–2571; Arch. Ration. Mech. Anal. 228 (2018), no. 2, 697–742) and holds for both 2D and 3D and hence gives a complete answer to the two open questions raised therein. Moreover, there is no loss of derivatives in our well‐posedness theory. The solution is constructed as the inviscid limit of solutions to some suitably‐chosen nonlinear approximate problems for the two‐phase compressible viscous non‐resistive MHD.

Published: September 2023

AbstractSemi‐organic materials consisting of organic and inorganic semiconductors, exhibit the characteristic properties like strong optical nonlinearity and thermal stability. Lithium Fumarate (LF) is grown as a semi‐organic single crystal using lithium hydroxide and fumaric acid employing a slow evaporation method with de‐ionized water as the solvent. Classical NucleationTheory (CNT) is used to calculate the speed of LF nucleation. By altering the temperature, the thermogravimetric (TG) models, namely Coats–Redfern and Piloyan–Novikova equations are used to calculate the kinetic parameters such as enthalpy, Gibbs free energy, real heat power, and entropy of activation values. The width of the metastable zone in the LF crystal is determined by evaluating the relationship between supersaturation and temperature and it is found to exhibit a linear dependence on temperature and possess positive solubility. Lithium Fumarate's (LF) photoconductivity test shows that the grown crystal has positive photoconductivity. Photoluminescence studies conclude that Correlated Colour Temperature (CCT) values and color purity of LF crystal are suited to the green light emitting devices and flat panel displays.

Can R&D investment be a key driver for sustainable development? Evidence from Korean industry
Authors: Baek Seungchul , Lee Duk Hee 
Published: September 2023

AbstractEnvironmental, social, and governance (ESG) management is an essential element for corporate sustainability. However, the effect of ESG management on corporate financial performance (CFP) is inconsistent, and not many studies have been conducted for Asia and developing countries, which are in the early stage of ESG management. In addition, although R&D investment influences ESG management, few studies have focused on the relationship between R&D investment, ESG, and CFP. We analyse the effect of ESG management on CFP using panel data combining ESG rating and financial data of Korean companies and examine moderating effect of R&D investment between ESG and CFP. We find the following results. First, ESG performance has a negative effect on CFP while there is no statistically significant effect in heavily polluting industries (HPI). Second, R&D investment has no significance on CFP, but a positive moderating effect exists between environmental (E) and social (S) performance and CFP. With environmental issues and climate change being a global concern, this study provides theoretical and managerial implications for companies to create synergies in R&D investment and ESG management.
Purification and Fractionation of Lignin via ALPHA: Liquid–Liquid Equilibrium for the Lignin–Acetic Acid–Water System
Authors: Agede Oreoluwa , Thies Mark C. 
Published: September 2023

AbstractIn order to effectively practice the Aqueous Lignin Purification with Hot Agents (ALPHA) process for lignin purification and fractionation, the temperatures and feed compositions where regions of liquid–liquid equilibrium (LLE) exist must be identified. To this end, pseudo‐ternary phase diagrams for the lignin–acetic acid–water system were mapped out at 45–95 °C and various solvent: feed lignin mass ratios (S : F). For a given temperature, the accompanying SL (solid–liquid), SLL (solid–liquid–liquid), and one‐phase regions were also located. For the first time, ALPHA using acetic acid (AcOH)–water solution was applied to a lignin recovered via the commercial LignoBoost process. In addition to determining tie‐line compositions for the two regions of LLE that were discovered, the distribution of lignin and key impurities (the latter can negatively impact lignin performance for materials applications) between the two liquid phases was also measured. As a representative example, lignin isolated in the lignin‐rich phase was reduced 7x in metals and 4x in polysaccharides by using ALPHA with a feed solvent composition of 50–55 % AcOH and an S : F of 6 : 1, with said lignin being obtained at a yield of 50–70 % of the feed lignin and having a molecular weight triple that of the feed.

SummaryService discovery (SD) is the cornerstone of wireless and mobile systems. The discovery of effective service is the key to achieve a higher level of ubiquity, which ensures the availability of services to users and applications significantly, and the high use of services. The research in this field is limited, with a few SD protocols available for specific purposes specified in the 6LoWPAN region. This paper discusses the various issues and challenges facing the design and selection of the appropriate service discovery and cluster‐based mechanism. Moreover, attention has been drawn to the cross‐layer solution by discussing different clustering techniques used to solve the redundancy problems. Furthermore, the service discovery protocols and cluster‐based routing protocols are critically investigated considering the redundancy problem, methods, mechanisms, and architectures by categorizing them into different categories, comparing them with fundamental parameters in the WSNs and MANETs environments. In addition, a modern form is proposed to show the life cycle of the service discovery process, and a new figure has been designed to clarify to the researchers various of the open issues related to the service discovery and cluster‐based routing protocols, corresponding objectives and the techniques of solving problems. Through the discussion of the scientific papers under survey, important results and valuable recommendations were reached. The survey is concluded with a summary, open research issues, outlook, and directions for future research on the topic.

AbstractThis study aims at investigating whether environmental enrichment (EE) initiated in adolescence can alter chronic unpredictable stress (CUS)‐associated changes in astroglial and synaptic plasticity markers in male and female rats. To this end, we studied possible alterations in hippocampal glial fibrillary acidic protein (GFAP) and synaptophysin (SYN) in CUS rats previously housed in EE. Wistar rats on postnatal day (PND) 23 were housed for 10 weeks in standard housing (SH) or enriched conditions. On PND 66, animals were exposed to CUS for 4 weeks. SYN and GFAP expressions were evaluated in CA1 and CA3 subfields and dentate gyrus (DG). CUS reduced the expression of SYN in all hippocampal areas, whereas lower GFAP expression was evident only in CA1 and CA3. The reduced expression of SYN in DG and CA3 was evident to male SH/CUS rats, whereas the reduced GFAP expression in CA1 and CA3 was limited to SH/CUS females. EE housing increased the hippocampal expression of both markers and protected against CUS‐associated decreases. Our findings indicate that the decreases in the expression of SYN and GFAP following CUS are region and sex‐specific and underline the neuroprotective role of EE against these CUS‐associated changes.

AbstractBody size is a trait that can affect plant–pollinator interaction efficiency and plant reproductive success. We explored the impact of intraspecific size shifts on the interactions between pollinators and flowering plants under controlled conditions. We considered two development conditions leading to the production of large and small individual flowers of Borago officinalis and Echium plantagineum. We also used the natural variability of worker size within bumblebee colonies to isolate small and large workers. We performed a fully crossed experiment with the two flower sizes of each plant species and the two sizes of bumblebee workers. Our results show that the size of both partners did not affect bee foraging behavior in most of the evaluated parameters and both bee sizes were equally efficient in depositing pollen. Significant differences were found only in pollen deposition across the life of a flower in small flowers of B. officinalis, with the greatest quantity of pollen deposited by small bees. We did not find a relationship between pollinator size and plant fitness. Our results suggest that generalist plant–pollinator interactions may be resilient to future potential mismatches in the size of the partners but remain to be tested if they are still resilient under the new environmental conditions resulting from global changes.

AbstractThe biological larvicide Bacillus thuringiensis var. israelensis (Bti) is used worldwide to control reproduction of mosquitoes in freshwater habitats. However, its impact on the ecosystem including nontarget species is often unclear. In addition, it is unknown how Bti larvicide may interact with local mosquito predators to shape oviposition site selection of mosquitoes. We used an outdoor mesocosm experiment to investigate the effects of realistic concentrations of the bio‐larvicide Bti on Culex oviposition, larval density, survivorship, and on densities of nontarget species. We also manipulated the complexity of the community by manipulating the presence of dragonfly larvae as a predator. Culex oviposition was unaffected by Bti but the larvicide effectively reduced larval density and survivorship in all treatments. Bti did not affect nontarget insects but stimulated phytoplankton density at the expense of lower herbivore density. The presence of dragonfly larvae in mesocosms did not reduce Culex oviposition or larval sensitivity to Bti. We conclude that Bti may effectively reduce the density and survivorship of Culex quinquefasciatus mosquitoes in this part of East Africa, but possibly at the cost of higher phytoplankton densities. Bti‐treated mesocosms were not more or less attractive for mosquitoes, suggesting that its application would not alter their oviposition behavior in the field.

AbstractEnantioseparation by the electromigration‐based method is well‐established and widely discussed in the literature. Electrophoretic strategies have been used to baseline resolve complex enantiomeric mixtures, typically using a selector substance into the background electrolyte (BGE) from capillaries to microchips. Along with developing new materials/substances for enantioseparations, it is the concern about the green analytical chemistry (GAC) principles for method development and application. This review article brings a last decade's update on the publications involving enantioseparation by electrophoresis for capillary and microchip systems. It also brings a critical discussion on GAC principles and new green metrics in the context of developing an enantioseparation method. Chemical and green features of native and modified cyclodextrins are discussed. Still, given the employment of greener substances, ionic liquids and deep‐eutectic solvents are highlighted, and some new selectors are proposed. For all the mentioned selectors, green features about their production, application, and disposal are considered. Sample preparation and BGE composition in GAC perspective, as well as greener derivatization possibilities, were also addressed. Therefore, one of the goals of this review is to aid the electrophoretic researchers to look where they have not.

Authors: Bhanupriya Periaswamy , Balasubramanian Ramachandran 
Published: September 2023

AbstractWhen individuals are accustomed to receiving information in automobiles, mobile data offloading is becoming more common. However, the effects of movement of the vehicle in correspondence to relative speed and direction between vehicles, have a significant impact on mobile data offloading. An innovative deep learning algorithm namely, intelligent deep neural network (IDNN) is proposed for vehicle data offloading and an optimal algorithm namely, quasi opposition based C‐hen swarm optimization (QOCSO) is proposed for efficient vehicle resource allocation. Initially, the vehicles in the vehicular networks are clustered with the help of the cosine similarity‐based K‐means algorithm for transmitting the data in an energy‐aware manner. Then cluster heads (CHs) are optimally selected for the generated clusters using Boltzmann selection probability‐based earth worm algorithm. The selected CHs are responsible for collecting the data from the cluster members and that is forwarded to the roadside unit. Then the suitable mobile edge servers are selected according to the IDNN algorithm that offloads the data from the CHs to the appropriate server. These received tasks of the vehicles could be stored as a blockchain for providing security to the vehicular network and finally, the resource allocation of the incoming tasks to the vehicles is performed using the QOCSO algorithm. Experiment findings reveal that both offloading and resource scheduling techniques outperform existing state‐of‐the‐art vehicular network algorithms.
