Published: April 2024

AbstractDelamination due to interfacial debonding between metal/composite is identified as a potential failure mechanism of fiber metal laminates (FML). In the present study, titanium based fiber metal laminate (Ti‐FML) were fabricated using different wt% of nanoclay modified epoxy as adhesive. Kevlar/jute fibers bidirectionally woven mat was used to prepare the composite layer in the laminate. The laminates produced using compression molding techniques were studied for tensile, flexural, impact load bearing capacity and adhesive strength based on lap shear and peel test following ASTM standards. Lap shear adhesive strength of nanoclay modified epoxy was enhanced to 27 MPa and interlaminar peel strength was increased to 16.8 N/mm in the laminates, when the amount of nanoclay was increased to 8 wt%. Matrix crack deflection and crack bridging due to the presence of nanoclay was identified as potential mechanism for increasing the adhesive strength of epoxy. Enhanced adhesive strength resulted in improved mechanical characteristics of Ti‐FML, exhibiting notable increases in tensile load bearing capacity at 15.5 kN, flexural peak load at 0.36 kN, and bending strength at 890 MPa, achieved with a 7 wt% increase in nanoclay content. Fiber breakage and plastic deformation of metal combinedly developed the failure deformation, load bearing and energy absorption capacity of the laminate. Hybridization of fibers kevlar/jute played a significant role in enhancing the energy absorption capacity of laminates. The developed material can find applications in aerospace structures, automotive components, and marine environments where superior mechanical performance and durability are essential.Highlights

AbstractIntroductionRhododendron arboreum Sm. flowers grow in the Himalayan region and have traditionally been used in beverages and food. These wild edible Himalayan flowers are known for their sweet–sour flavor and beautiful scarlet red color. The primary pigments responsible for the scarlet red color of these flowers are anthocyanins.ObjectiveIn the present study, we conducted chemo‐profiling and elucidated the chromatic characteristics of R. arboreum flower petals growing in the wild in different altitudinal areas.MethodologyThe content of anthocyanins, phenolics, and other flavonoids was determined in R. arboreum flower petals collected from 38 different locations in two provinces in India (Himachal Pradesh and Uttarakhand) to obtain a distinguishable chemical index. A UHPLC method has also been developed and validated for the quantitative analysis. Besides, the color characteristics of each collected floral sample were also analyzed.ResultsChemometric analysis (principal component analysis [PCA] and heatmap analysis) revealed that floral samples collected from different altitudes exhibited similar chemical diversity, whereas statistical analysis (bivariate linear correlation) revealed a positive correlation between the color parameter a*/b* and cyanidin glycosides. Besides, non‐targeted metabolomics analysis was carried out, which resulted in the tentative identification of 150 metabolites.ConclusionThe results revealed that there is a direct influence of accumulated anthocyanins to color parameter a*/b* values in the floral samples irrespective of altitude.

AbstractTo explore the genetic causal association between pulmonary artery hypertension (PAH) and iron status through Mendelian randomization (MR), we conducted MR analysis using publicly available genome‐wide association study (GWAS) summary data. Five indicators related to iron status (serum iron, ferritin, total iron binding capacity (TIBC), soluble transferrin receptor (sTfR), and transferrin saturation) served as exposures, while PAH was the outcome. The genetic causal association between these iron status indicators and PAH was assessed using the inverse variance weighted (IVW) method. Cochran's Q statistic was employed to evaluate heterogeneity. We assessed pleiotropy using MR‐Egger regression and MR‐Presso test. Additionally, we validated our results using the Weighted median, Simple mode, and Weighted mode methods. Based on the IVW method, we found no causal association between iron status (serum iron, ferritin, TIBC, sTfR, and transferrin saturation) and PAH (pβ > 0.05). The Weighted median, Simple mode, and Weighted mode methods showed no potential genetic causal association (pβ > 0.05 in the three analyses). Additionally, no heterogeneity or horizontal pleiotropy was detected in any of the analyses. Our results show that there are no genetic causal association between iron status and PAH.

Published: April 2024

AbstractIn this article, we study the leader‐following formation problem for high‐order nonlinear multi‐agent systems with an uncertain leader system over switching networks. We first divide the uncertain leader system into two types and then design adaptive distributed observers for them respectively. Then, based on our designed observers, we synthesize two adaptive distributed control laws respectively to solve our problem, forcing the errors between the states of the followers and that of the leader to the prescribed time‐varying desired formation vectors. Finally, our main result is illustrated by two examples.

Abstract3D composite electrodes have shown extraordinary promise as high mass loading electrode materials for sodium ion batteries (SIBs). However, they usually show poor rate performance due to the sluggish Na+ kinetics at the heterointerfaces of the composites. Here, a 3D MXene‐reduced holey graphene oxide (MXene‐RHGO) composite electrode with Ti─O─C bonding at 2D heterointerfaces of MXene and RHGO is developed. Density functional theory (DFT) calculations reveal the built‐in electric fields (BIEFs) are enhanced by the formation of bridged interfacial Ti─O─C bonding, that lead to not only faster diffusion of Na+ at the heterointerfaces but also faster adsorption and migration of Na+ on the MXene surfaces. As a result, the 3D composite electrodes show impressive properties for fast Na+ storage. Under high current density of 10 mA cm−2, the 3D MXene‐RHGO composite electrodes with high mass loading of 10 mg cm−2 achieve a strikingly high and stable areal capacity of 3 mAh cm−2, which is same as commercial LIBs and greatly exceeds that of most reported SIBs electrode materials. The work shows that rationally designed bonding at the heterointerfaces represents an effective strategy for promoting high mass loading 3D composites electrode materials forward toward practical SIBs applications.

AbstractSemiconductor‐based materials utilized in photocatalysts and electrocatalysts present a sophisticated solution for efficient solar energy utilization and bias control, a field extensively explored for its potential in sustainable energy and environmental management. Recently, 3D printing has emerged as a transformative technology, offering rapid, cost‐efficient, and highly customizable approaches to designing photocatalysts and electrocatalysts with precise structural control and tailored substrates. The adaptability and precision of printing facilitate seamless integration, loading, and blending of diverse photo(electro)catalytic materials during the printing process, significantly reducing material loss compared to traditional methods. Despite the evident advantages of 3D printing, a comprehensive compendium delineating its application in the realm of photocatalysis and electrocatalysis is conspicuously absent. This paper initiates by delving into the fundamental principles and mechanisms underpinning photocatalysts electrocatalysts and 3D printing. Subsequently, an exhaustive overview of the latest 3D printing techniques, underscoring their pivotal role in shaping the landscape of photocatalysts and electrocatalysts for energy and environmental applications. Furthermore, the paper examines various methodologies for seamlessly incorporating catalysts into 3D printed substrates, elucidating the consequential effects of catalyst deposition on catalytic properties. Finally, the paper thoroughly discusses the challenges that necessitate focused attention and resolution for future advancements in this domain.

AbstractThe role of tannins (TA), a well‐known abundant and ecologically friendly chelating ligand, in metal capture has long been studied. Different kinds of TA‐containing adsorbents are synthesized for uranium capture, while most adsorbents suffer from unfavorable adsorption kinetics. Herein, the design and preparation of a TA‐containing 2D crosslinked network adsorbent (TANP) is reported. The ≈1.8‐nanometer‐thick TANP films curl up into micrometer‐scale pores, which contribute to fast mass transfer and full exposure of active sites. The coordination environment of uranyl (UO22+) ions is explored by integrated analysis of U L3‐edge XANES and EXAFS. Density functional theory calculations indicate the energetically favorable UO22+ binding. Consequently, TANP with excellent adsorption kinetics presents a high uranium capture capacity (14.62 mg‐U g‐Ads−1) and a high adsorption rate (0.97 mg g−1 day−1) together with excellent selectivity and biofouling resistance. Life cycle assessment and cost analysis demonstrate that TANP has tremendous potential for application in industrial‐scale uranium extraction from seawater.

Published: April 2024

AbstractAn IoT‐based monitoring system remotely controls and manages intelligent environments. Due to wireless communication, deployed sensor nodes are more vulnerable to attacks. An intrusion detection system is an efficient mechanism to detect malicious traffic and prevent abnormal activities. This article suggests an intrusion detection framework for the cold storage monitoring system. The temperature is the main parameter that affects the environment and harms stored products. A malicious node injects false data that manipulates temperature and forwards manipulated data. It also floods the data to neighbor nodes. In this work, data are generated and collected for intrusion detection. Two machine learning techniques have been applied: supervised learning (Bayesian rough set) and unsupervised learning (micro‐clustering). The proposed method shows better performance than existing methods.

AbstractCommonly considered bispecific, Acorus is one of the most phylogenetically isolated angiosperm genera that forms the order Acorales sister to the rest of the monocots. The Acorus calamus group is widely distributed in the Holarctic regions of Eurasia and America and has strong medicinal and other practical uses since prehistoric times. Earlier studies interpreted native diploids and invasive triploids occurring in North America as two species that differed in morphology and distribution ranges. In contrast, diploids, triploids, and tetraploids occurring in Eurasia are commonly interpreted as one species because they reportedly cannot be distinguished in collections. We resolve the controversy over taxonomic concepts between Eurasia and America and provide the first detailed multidisciplinary account of Acorus in temperate Asia. We used plastid and nuclear markers, leaf anatomy, seed micromorphology, pollen stainability, flow cytometry, and direct chromosome counts. Diploids and tetraploids show stable molecular and micromorphological differences. Triploids are their sterile hybrids, with the plastid genome inherited from the diploid parent. Diploids of America and Asia tend to differ in leaf characters. Coadaptative coexistence with pollinating beetles Platamartus jakowlewi and Sibirhelus corpulentus (Kateretidae) is conserved between diploids and tetraploids and over a distance of 4700 km between Japan and Western Siberia. Diploids are self‐compatible and can set seeds in the absence of kateretid beetles. Tetraploids are self‐incompatible and/or cannot set seeds in the absence of Platamartus and Sibirhelus. Diploids (A. americanus) and tetraploids (A. verus) are two biological species; the former has two subspecies. Acorus calamus should be restricted to triploids; it apparently first evolved in temperate Asia. Diploids mostly occur in much cooler climates than triploids and tetraploids. Accessions of A. verus and A. calamus from tropical Asia are apparently derived from ancient introductions. Our data provide a new framework for the pharmacological use of Acorus.
Better to deliver tomorrow morning than late today? The time‐of‐day effect in customer perception of online sellers' logistics service quality

Published: April 2024

AbstractDrawing upon energy depletion theory and expectancy disconfirmation theory, this study aims to zoom in on the effect of delivery time on customer perception of online seller logistics service quality (LSQ). We conjecture that customer rating of LSQ will vary depending on the delivery time in a day (i.e., the time‐of‐day effect). With a large sample consisting of more than 42 million orders from Alibaba, the results from mixed‐effects ordered logit model corroborate the time‐of‐day effect and that promised delivery service interacts with the time‐of‐day effect by strengthening it. Following that, machine learning techniques are employed to quantify the importance of the different predictors and results show that the time‐of‐day effect is the most important predictor. The study reveals a new time‐related attribute, contributes to the LSQ framework, and has important managerial implications for practitioners.
Evaluation using the SWAT model of the effects of land use land cover changes on hydrological processes in the Gala Lake Basin, Turkey
Authors: Keleş Özgenç Emine 
Published: April 2024

AbstractChanges in hydrological processes in watersheds are triggered by various factors, including land use land cover changes (LULCC) emerging from human activities. Hence, it is crucial to elucidate the interaction among hydrological processes to improve sustainable water management plans. The current study explored the effects of LULCC on hydrological processes in the Gala Lake catchment over a 30‐year temporal period. In this context, to evaluate LULCC, land cover maps were obtained using the supervised classification method with Landsat images (5 TM, 7 ETM+, 8 OLI) of 1993, 2008, and 2023. Hydrological processes were assessed using the Soil and Water Assessment Tool (SWAT), a commonly applied eco‐hydrological model. The model was utilized to evaluate the potential effect of LULCC on processes like surface runoff, infiltration, evapotranspiration, and erosion. Between 1993 and 2023, significant LULCC have been observed in the study area. There has been a decrease of 4.3%, 1%, 1.6%, and 5.3% in agricultural lands, forested lands, inland marshes, and pasture lands, respectively, while artificial surfaces, rice fields, and water bodies have seen an increase of 7%, 3.4%, and 1.9%, respectively. The potential effects of these changes were observed as a decrease in the runoff, a decrease in permeability, and an increase in processes such as evapotranspiration and erosion throughout the basin and sub‐basin. In general, LULCC significantly affect the hydrological status of the catchment. Therefore, establishing different conservation and utilization strategies that consider land use dynamics to maintain the resilience of ecosystems in the basins is vital in the sustainable management of water resources.

AbstractImplementing a newly developed spectrometer for the soft x‐ray range of (35–130) eV based on reflection zone plates was successfully accomplished on an electron probe microanalyzer. In this context, we present the first spectra acquired using this setup, including those of elements such as Be (Kα), C (Kα), Mg (L2,3), Al (L2,3), and Si (L2,3). We have also conducted an analysis of several lithium compounds and measured the emission of Li Kα from metallic Li, LiF, and LiNbO3. Some of the results were compared with density functional theory calculations. The spectrum obtained for the lithium‐bearing mineral amblygonite Li0.75Na0.25Al(PO4)F0.75(OH)0.25 is chosen to discuss some of the challenges faced.

AbstractCurrently, digital reconstructions are mainly a process in one single context by interdisciplinary workgroups using expert technologies. 3D reconstructions in the humanities are primarily created within long-term interdisciplinary projects. This chapter provides an overview of the team processes and workflows to create 3D reconstructions. Interdisciplinary teamwork creates specific challenges due to the different work processes of the disciplines involved—e.g., humanities, design, and computing. Since 3D reconstructions are projects, both processes and quality need to be managed. This chapter contains a set of empirically grounded recommendations for the organization and management of 3D reconstruction projects.

Harmony via Reductions and Expansions
Authors: Tranchini Luca 
Published: April 2024

AbstractThe notion of harmony arises by considerations about the notion of assertion in the theory of meaning. When applied to rules in the format of natural deduction, harmony can be explained by making reference to certain transformations on derivations, called reductions and expansions. Reductions are a key ingredient of the proof of normalization for the calculus of natural deduction for intuitionistic logic. In this calculus, normal derivations that are closed (i.e. such that their conclusions depend on no assumption) end with an introduction rule, a fact which is referred to as the canonicity of closed normal derivations. The condition for the canonicity of normal derivations in a more general setting are discussed. The chapter ends with a brief discussion of other accounts of harmony.
Identity of Proofs
Authors: Tranchini Luca 
Published: April 2024

AbstractProof-theoretic semantics is here presented as primarily concerned with the investigation of the relationship between proofs (understood as abstract entities) and derivations (the linguistic representations of proofs). This relationship is taken to be analogous to that between names and (abstract) objects in Frege. On this conception of proof-theoretic semantics, reductions and expansions should be viewed as identity-preserving operations on derivations and thus as inducing an equivalence relation on derivations such that equivalent derivations denote the same proof. Using this equivalence on derivations it is possible to define an equivalence relation on formulas that is stricter than interderivability, called isomorphism. We argue that identity of proofs and formula isomorphism show the intensional nature of this conception of proof-theoretic semantics. Finally, this conception is compared to the one advocated by Dummett and Prawitz, which is based on a notion of validity of derivations.
Institutions

AbstractThis chapter is concerned with the design, implementation, and outcomes of current social protection institutions in the region. It examines in turn the three core social protection institutions: occupational pensions, individual retirement savings plans, and social assistance. Occupational pensions in Latin America are restricted to selected groups of workers, mainly skilled workers in large firms. They are also highly fragmented and dependent on public subsidies, although the level of subsidies is increasingly contested. Recent trends in labour force participation in occupational pensions suggest stagnation during this century. Individual retirement savings plans are based on individual workers’ saving capacity. They were initially implemented in ten countries in the region, under different modalities. Individual retirement savings plans have not proved successful in the region, and it is fair to say their institutional structures are in transition. Social assistance greatly expanded in the new century. Most countries in the region have implemented large scale old age transfers and conditional income transfer programmes. By 2015, social assistance transfers reached around one third of the population in the region.
