Geometric stabilization of discrete‐time systems via dissipativity approach and output feedback control
Authors: Wen Xinyuan , Yang Fan , Ren Yuanhong , Bai Xuejie 
Published: September 2024

AbstractGeometric stabilizability is studied for nonlinear discrete‐time systems (DTS) utilizing linear static output feedback (SOF). Initially, a linear SOF controller is designed such that nonlinear DTS achieve geometric stabilizability. Utilizing the concept of geometric QSR‐dissipativity (GQSR‐D), a condition both sufficient and necessary is proffered to guarantee geometric stabilizability for nonlinear DTS. Subsequently, the necessary conditions of linear matrix inequality (LMI) are delineated to ascertain the stability of a system employing linear SOF. A new sufficient and necessary condition is provided aiming to stabilize the linear time‐invariant (LTI) DTS based on GQSR‐D. Lastly, examples are furnished to elucidate the efficacy of the results, thereby reinforcing their practical applicability.

Published: September 2024

ABSTRACTCyberspace is a dynamic ecosystem consisting of interconnected data, devices, and individuals, with multiple network layers comprising identifiable nodes. Location‐based information can significantly improve cyber resilience decision‐making and facilitate the development of innovative cyber risk pricing tools. This article is based on a methodology that uses company geospatial data to accurately estimate the number of expected losses arising from cyberattacks. Our approach aims to build and compare statistical spatial models that allow pricing cyber policies more effectively than traditional non‐spatial methods by incorporating all available data. By accounting for spatial dependence, we can assess the risk of data breaches and contribute to the design of more efficient cyber risk policies for the insurance market.
Interfacial challenges and recent advances of solid‐state lithium metal batteries
Authors: Jeong Wooyoung , Yun Jonghyeok , Lee Jong‐Won 
Published: September 2024

AbstractGrowing market demands on portable electronics, electric vehicles, and energy storage system calls for the development of high‐energy density lithium (Li) batteries. Li metal is considered as a promising anode material owing to their high capacity and low electrochemical potential. However, high reactivity of Li metal with conventional flammable liquid electrolytes easily forms Li dendrites, which may cause short‐circuit and even catching fire, obstructing the wide application of Li metal batteries. Although non−/less‐flammable solid electrolytes have replaced the conventional liquid electrolytes, solid‐state Li metal batteries (SSLMBs) suffer from lower Li+ conductivities, chemical/electrochemical incompatibilities toward Li metal, and inhomogeneous Li+ flux at the interfaces. Therefore, many researchers have devoted themselves to solve these problems. For a better understanding on the current issues and recent advances, this article provides (1) a review on various solid electrolytes with high Li+ conductivity and their interfacial issues in SSLMBs, and (2) recent progress in stabilization of the interface between the Li node and solid electrolytes, including an electrolyte modification (e.g., composition, additives) and introduction of an interlayer.
Corporate environmental behavior toward sustainable development: Motivations, benefits, and challenges of ISO 14001 adoption at Japanese subsidiaries in Thailand

Published: September 2024

AbstractSince the Earth Summit held in Rio de Janeiro in 1992, ISO 14001 has become an internationally recognized environmental management system that has spread all over the world. The existing literature has examined in detail the motivations, benefits, and challenges of ISO 14001 adoption in developed countries. However, there is a relative lack of studies on the adoption of ISO 14001 by the subsidiaries of multinational corporations (MNCs) in developing countries, and in Thailand in particular. This paper investigates the motivations, benefits, and challenges of ISO 14001 adoption at Japanese subsidiaries in Thailand based on the results of a questionnaire survey of 100 subsidiaries and a semi‐structured interview survey of 11 subsidiaries. We find that the main motivations are pressures by the national and local governments, as well as by the customers. In addition to the tax incentives, the main benefits are gaining competitiveness, enhancing the corporate image, and maintaining efficient management. We also identify the following challenges: the costs of ISO 14001 adoption, and the training and awareness of the employees. Compared with the existing literature, we find some new motivations, benefits, and challenges related to the local context of ISO 14001 adoption. Although our results are valid only for the Japanese subsidiaries in Thailand, the in‐depth understanding of the motivations, benefits, and challenges of ISO 14001 adoption may contribute to the expanding literature about corporate environmental behavior toward sustainable development.

AbstractMarine sponges are valuable sources of bioactive compounds, which have attracted pharmacological interest. This study aimed to evaluate the chemical profile, antioxidant, and antibacterial activities of the species Desmapsamma anchorata, Dysidea etheria, and Echinodictyum dendroides. The chemical profile involved identifying and quantifying polyphenols, and antioxidant activity was evaluated using various methods. The antibacterial and modulatory activities were evaluated using microdilution against pathogenic strains. The extracts contained a low amount of polyphenols. In the antioxidant assays, the EACDa and EMDa extracts exhibited better inhibitory results. In the antibacterial evaluation, extracts presented MIC ≥1024 μg mL−1. The modulation of the extracts combined with antibiotics showed significant effects against the multiresistant bacterium Pseudomonas aeruginosa. This study contributes to the deepening of chemical and biological knowledge of sponge species. It indicates that their extracts can act as good modulators of bacterial resistance to aminoglycoside antibiotics, which requires further investigation into their mechanisms of action.

Revealing the Mechanism of Ketonization of Acetic Acid on HBEA Zeolite via Metadynamics Simulations

Published: September 2024

AbstractKetonization of biomass‐derived carboxylic acids offers a promising approach to remove oxygen and upgrade into valuable chemicals. However, the mechanism on Brønsted acid site (BAS) confined in micropores of zeolite remains elusive, due to the difficulty to observe the reaction intermediates experimentally and to locate the transition state via static density functional theory (DFT) calculations. Herein, ketonization of acetic acid on HBEA at 673 K was studied by metadynamics simulations based on DFT. The first reaction step was the concerted protonation and dehydroxylation of acetic acid, resulting in an electrophilic acylium cation and H2O (ΔG‡ = 1.53 eV). The subsequent likely steps, including C─C coupling through the nucleophilic attack of acetic acid (path I), ketene (path II), and 1,1‐dihydroxyethene (path III) toward acylium cation were tracked and compared. The high barriers for formation of more nucleophilic intermediates of ketene and 1,1‐dihydroxyethene made the overall path II and III less favorable than the direct coupling between acetic acid and acylium cation (path I, ΔG‡ = 2.15 eV). These results indicate that acylium cation is a key intermediate, and the C─C coupling between acetic acid and acylium cation via nucleophilic attack is the most favorable path on BAS confined in zeolite.

Published: September 2024

AbstractPhotoelectrochemical (PEC) technology is a promising strategy that can directly convert sunlight into chemical energy. Direct solar water splitting through the PEC process is a desirable method for green hydrogen (H2) production. This technology has also the potential to capture CO2 and convert it into fuels using sunlight and water, besides converting N2 and H2O to produce ammonia (NH3), which acts as transportable H2 storage. The cracking of NH3 to produce H2 can also be accomplished using PEC technology. Despite improved PEC performance having been shown, stability, efficiency, and scalability issues still need to be resolved. Even so, PEC technology has much potential as a clean and sustainable solution for addressing global energy and environmental challenges.

AbstractCannabidiol (CBD) is garnering increasing interest due to its significant biological activity. This natural compound is one of the major cannabinoids in Cannabis sativa L. In this work, we describe the encapsulation of CBD in solid and hollow pH‐sensitive poly(4‐vinylpyridine) (solid@p4VP and hollow@p4VP) nanoparticles, and temperature‐sensitive poly(N‐isopropylacrylamide) (solid@pNIPAM and hollow@pNIPAM) nanoparticles for transport and release CBD in a controlled manner. The CBD loading into these smart polymeric systems was effective and their release profiles, solubility and resistance to stomach and intestinal conditions were evaluated, showing satisfactory properties and improved bioavailability with respect to free CBD. Finally, the A549 human lung cancer cell line was used as lung adenocarcinoma epithelial cellular model to carry out preliminary assays of the in vitro activity of the vehiculized CBD. For all these studies, synthetic CBD was employed, for which a new efficient and scalable synthesis of cannabinoids has been developed.

Published: September 2024

AbstractOne of the most recent focuses in supramolecular chemistry is developing molecules designed to exhibit programmable properties at the molecular level. Rotaxanes, which function as molecular machines with movements controlled by external stimuli, are prime candidates for this purpose. However, the controlled synthesis of rotaxanes, especially amide‐benzylic rotaxanes with more than two components, remains an area ripe for exploration. In this study, we aim to elucidate the formation of amide‐benzylic [3]rotaxanes using a thread that includes a conventional succinamide station and an innovative triazole‐carbonyl station. Including the triazole‐carbonyl station introduces new perspectives into the chemistry of rotaxanes, influencing their conformation and dynamics. The synthesis of two‐station rotaxanes with varying stoppers demonstrated that the macrocycle consistently occupies the succinamide station, providing greater stability as evidenced by NMR and SC‐XRD analyses. The presence of a triazole‐carbonyl station facilitated the formation of a second macrocycle exclusively when a secondary amide was employed as the stopper group, presumably due to decreased steric hindrance. Moreover, the second macrocycle directly forms at the triazole‐carbonyl station. This investigation reveals that slight modifications in the thread structure can dramatically impact the formation, stability, and interactions between components of rotaxanes.
Research on microscale displacement characteristics of supercritical CO2 fracturing in shale oil reservoirs
Authors: Dai Xiaodong 
Published: September 2024

AbstractThe great success of CO2 fracturing in shale oil reservoirs has not only increased the production capacity of shale oil, but also effectively carried out CO2 geological storage. In this paper, focusing on the microscale displacement characteristics of CO2 fracturing in shale oil reservoirs, first, the impact of oil saturation and gas invasion pressure on gas invasion is discussed. Then, the coupling control mode of oil saturation/pressure for various mechanisms of gas invasion is revealed. Results show that: (a) at lower displacement, the rock core has a lower initiation pressure and is fractured in a shorter period of time; (b) at higher displacement, the required fracturing time is longer and the fracturing pressure increases, but the fracturing effect is good and it is easy to form complex fracture networks; and (c) under higher pressure conditions, more complex fractures can be formed, which is beneficial for reservoir transformation and production improvement.
Vulnerability detection based on transformer and high‐quality number embedding
Authors: Cao Yang , Dong Yunwei , Peng Jiajie 
Published: September 2024

SummarySoftware vulnerability detection is an important problem in software security. In recent years, deep learning offers a novel approach for source code vulnerability detection. Due to the similarities between programming languages and natural languages, many natural language processing techniques have been applied to vulnerability detection tasks. However, specific problems within vulnerability detection tasks, such as buffer overflow, involve numerical reasoning. For these problems, the model needs to not only consider long dependencies and multiple relationships between statements of code but also capture the magnitude property of numerical literals in the program through high‐quality number embeddings. Therefore, we propose VDTransformer, a Transformer‐based method that improves source code embedding by integrating word and number embeddings. Furthermore, we employ Transformer encoders to construct a hierarchical neural network that extracts semantic features from the code and enables line‐level vulnerability detection. To evaluate the effectiveness of the method, we construct a dataset named OverflowGen based on templates for buffer overflow. Experimental comparisons on OverflowGen with a well‐known static vulnerability detector and two state‐of‐the‐art deep learning‐based methods confirm the effectiveness of VDTransformer and the importance of high‐quality number embeddings in vulnerability detection tasks involving numerical features.

AbstractCrystalline ZIF‐8 (C‐ZIF‐8) and amorphous ZIF‐8 (Am‐ZIF‐8) were prepared and investigated to control the germination of Striga hermonthica, a root parasitic plant, which threatens cereal crops production particularly in sub‐Saharan Africa. We have demonstrated that Am‐ZIF‐8 shows a better performance than C‐ZIF‐8 in inhibiting Striga seeds germination. This efficient performance of Am‐ZIF‐8 materials can be attributed to the incomplete deprotonation of 2 methylimidazole (2MIM) during amorphization, leading to the presence of unsaturated Zn−N coordination with the uncoordinated ‐NH groups available to undergo hydrogen bonding with the strigolactone analog GR24 forming a more stable Am‐ZIF‐8⋅⋅⋅GR24 hydrogen bonded network. We further established that application of ZIF‐8 materials generally has no adverse effects on the growth and quality of rice crops.

ABSTRACTObjectiveThe objective of this study was to provide an updated analysis of suicide characteristics in China from 2002 to 2021, with the aim of informing the development of evidence‐based suicide prevention strategies.MethodsThe Ministry of Health‐Vital Registration System (MOH‐VR) provided the data on suicide mortality, which enabled us to examine the average annual percentage change (AAPC) in suicide rates using a Poisson regression model.ResultsNotably, there has been a significant decline in suicide rates observed in both urban and rural areas. In the early years of the study period, higher suicide rates were observed among females compared to males; however, a shift occurred after 2005, with male suicide rates surpassing those of females. Except for 2005, rural areas consistently exhibited higher suicide rates than urban areas. Furthermore, suicide rates exhibited an increasing trend with age, irrespective of gender or region.ConclusionThese findings highlight a decreasing trend in suicide rates in China over the past two decades, although gender and regional disparities persist. Going forward, sustained efforts in suicide prevention, with a specific focus on mental health, are warranted.
Effects of turfgrass canopy shade levels and quantum spectrum on the germination and development of smooth crabgrass (Digitaria ischaemum)
Authors: Vuković Vera , Law Quincy D. , Patton Aaron J. 
Published: September 2024

AbstractSmooth crabgrass [Digitaria ischaemum (Schreb.) Schreb. ex Muhl.] is one of the most troublesome summer annual weeds in cool‐season turfgrass. Field experiments demonstrated a strong relationship between spring photosynthetic active radiation reaching the soil surface and the resulting smooth crabgrass cover in Kentucky bluegrass (Poa pratensis L.) 2/3 months later in summer. Both smooth crabgrass and canopy penetrating light were consistently reduced by higher mowing heights. Follow‐up experiments in controlled environments were initiated to improve our understanding of how light quality and quantity influence smooth crabgrass germination and growth. Smooth crabgrass germination was ≥99% following exposure to blue, red (R), far red (FR), both R and FR light pulses, or complete darkness treatments. A second germination experiment examined six levels of turfgrass canopy shade (0%, 24%, 44%, 77%, 90%, and 100% photosynthetic photon flux density [PPFD] reduction) and found that smooth crabgrass germination was ≥99% for all treatments. These experiments indicate that light quality and quantity do not affect smooth crabgrass germination. A greenhouse experiment examined five levels of turfgrass canopy shade (0%, 44%, 59%, 81%, and 91% PPFD reduction). Smooth crabgrass quantum and PSII (Photosystem II) operating efficiency increased in response to shade, while leaf number and thickness, specific leaf weight, tillering, mass, electron transport rate, and stomatal conductance decreased with increasing shade. Overall, the results demonstrate that smooth crabgrass is able to germinate regardless of canopy density, but seedling growth, development, and plant function are diminished in a dense turfgrass canopy shade.

AbstractSpring dead spot (Ophiosphaerella spp.; SDS) is one of the most detrimental diseases to warm‐season turfgrasses, particularly bermudagrass (Cynodon spp.), growing in climates where cold temperatures induce dormancy. The pathogen can infect the crowns, stolons, rhizomes, and roots of bermudagrass most of the year, but infection in the fall predisposes the turf to winter injury and plant death. Symptoms typically appear the following spring, making management of SDS challenging. Moreover, the biology, epidemiology, and management of SDS are not fully understood. Ample research has been conducted on SDS which was thoroughly summarized before 2009 by Tredway et al. Since then, 18 new research papers have been published over the last 15 years that have further clarified the biology, epidemiology, and management of SDS. This review seeks to compile, update, and summarize research developments on SDS from 2009 to 2024. Research developments over the last 15 years include an increased understanding of the biology and infection mechanisms of the Ophiosphaerella species that cause SDS, a greater knowledge of the epidemiology of the disease and factors that affect its distribution, as well as improved cultural and chemical management practices for SDS.
