Integrative Brain States Facilitate the Expression of Parkinson's Tremor
Authors: Dirkx Michiel F. , Shine James M. , Helmich Rick C. 
Published: June 2023

AbstractBackgroundParkinson's disease (PD) rest tremor emerges from pathological activity in the basal ganglia and cerebello‐thalamo‐cortical circuits. A well‐known clinical feature is the waxing and waning of PD tremor amplitude, but the mechanisms that drive this variability are unclear. Previous work has shown that arousal amplifies PD tremor by increasing between‐network connectivity. Furthermore, brain states in PD are biased toward integration rather than segregation, a pattern that is also associated with increased arousal.ObjectiveThe aim was to test the hypothesis that fluctuations in integrative brain states and/or arousal drive spontaneous fluctuations in PD rest tremor.MethodsWe compared the temporal relationship between cerebral integration, the ascending arousal system, and tremor, both during cognitive load and in the resting state. In 40 tremor‐dominant PD patients, we performed functional magnetic resonance imaging using concurrent tremor recordings and proxy measures of the ascending arousal system (pupil diameter, heart rate). We calculated whole‐brain dynamic functional connectivity and used graph theory to determine a scan‐by‐scan measure of cerebral integration, which we related to the onset of tremor episodes.ResultsFluctuations in cerebral integration were time locked to spontaneous changes in tremor amplitude: cerebral integration increased 13 seconds before tremor onset and predicted the amplitude of subsequent increases in tremor amplitude. During but not before tremor episodes, pupil diameter and heart rate increased and correlated with tremor amplitude.ConclusionsIntegrative brain states are an important cerebral environment in which tremor‐related activity emerges, which is then amplified by the ascending arousal system. New treatments focused on attenuating enhanced cerebral integration in PD may reduce tremor. © 2023 The Authors.

Published: June 2023

Impact statementHabitat loss has been a primary threat to biodiversity. However, species do not function in isolation but often associate with each other and form complex networks. Thus, revealing how the network complexity and stability scale with habitat area will give us more insights into the effects of habitat loss on ecosystems. In this study, we explored the relationships between the island area and the network complexity and stability of soil microbes. We found that the complexity and stability of soil microbial co‐occurrence networks scale positively with island area, indicating that habitat loss will potentially simplify and destabilize soil microbial networks.
Analytical modeling on the vibration response of a beam‐stiffened Mindlin thick plate with free boundary conditions
Authors: Guo Hui , Zhang Kai 
Published: June 2023

AbstractThis paper presents a new analytical solution for the vibration response of a beam‐stiffened Mindlin plate having a completely free boundary condition by utilizing a finite cosine integral transform. In the solution, the unknown coupling force and moments at the beam/plate interface and the unknown modal constants from the integral transform are determined by the continuity and compatibility conditions at the interface as well as the boundary conditions. It provides an easily implemented tool for exploring complex edge value problems for a class of higher‐order partial differential equations represented by fully free‐stiffened Mindlin thick plates. The validity of the model is evaluated by comparing the calculated free and forced vibration responses of the beam‐stiffened plate with those calculated using a beam‐stiffened thin plate and those from finite element analysis.

Published: June 2023

AbstractAnomaly detection of sequences is a hot topic in data mining. Anomaly detection using piecewise aggregate approximation in the amplitude domain (called ADPAAD) is one of the widely used methods in anomaly detection of sequences. The core step in the classical algorithm for performing ADPAAD is to construct an approximate representation of the subsequence, where the elements of each subsequence are divided into several subsections according to the amplitude domain, and then the average of the subsections is computed. It is computationally expensive when processing large‐scale sequences. In this paper, a quantum algorithm for ADPAAD is proposed, which can divide the subsequence elements and compute the average in parallel. The quantum algorithm can achieve polynomial speedups on the number of subsequences and the length of subsequences over its classical counterpart.

Published: June 2023

AbstractIn this article, three different types of stochastic asymptotic stability for nonlinear stochastic semi‐Markov jump systems (SSMJS) are investigated. Novel sufficient conditions for th ‐moment asymptotic stability, almost sure asymptotic stability and stochastic asymptotic stability in the large are obtained. It is remarkable that the obtained results in the latter case cover the results in existing literature. Finally, two examples are presented to confirm the validity of the obtained theoretical results.

Published: June 2023

AbstractBismuth chalcohalides (BiSeI and BiSI), a class of superior light absorbers, have recently garnered great attention owing to their promise in constructing next‐generation optoelectronic devices. However, to date, the photodetection application of bismuth chalcohalides is still limited due to the challenge in controllable preparation. Herein, the synthesis of large‐scale quasi‐1D BiSeI nanowires via chemical vapor deposition growth is reported. By precisely tuning the growth temperature and the Se supply, it can effectively control the growth thermodynamics and kinetics of BiSeI crystal, and thus achieve high purity quasi‐1D BiSeI nanowires with high crystal quality, uniform diameter, and tunable domain length. Theory and optical characterizations of the quasi‐1D BiSeI nanowires reveal an indirect bandgap of 1.57 eV with prominent optical linear dichroism. As a result, the quasi‐1D BiSeI nanowire‐based photodetector demonstrates a broadband photoresponse (400–800 nm) with high responsivity of 5880 mA W−1, fast response speed of 0.11 ms and superior air stability. More importantly, the photodetector displays strong polarization sensitivity (anisotropic ratio = 1.77) under the 532 nm light irradiation. This work will provide important guides to the synthesis of other quais‐1D metal chalcohalides and shed light on their potential in constructing novel multifunctional optoelectronic devices.

Published: June 2023

AbstractThe compatibility of crystallinity, stability, and functionality in covalent organic frameworks (COFs) is challenging but significant in reticular chemistry and materials science. Herein, it is presented for the first time a strategy to synthesize directly amino‐functionalized COF with stable benzodiimidazole linkage by regioselective one‐step cyclization and aromatization. Bandrowski's base with two types of amino groups is used as a unique monomer, providing not only construction sites for the material framework through specific region‐selective reaction, but also amino active sites for functionality, which is usually difficult to achieve directly in COF synthesis because amino groups are the participants in COF bonding. In addition, the aromatic benzodiimidazole rings and the large conjugated system of the product effectively improve the crystallinity and stability, so that the as‐prepared BBCOF remains unchanged in both acid and base solutions, which is obviously better than the conventional imine‐linked COF. Impressively, the significantly enhanced conjugation degree by the benzodiimidazole structure also endows BBCOF with an efficient photocatalytic reduction of uranyl ion, with removal rate as high as 96.6% in single‐ion system and 95% in multi‐ion system. This study is of great importance to the design and synthesis of functional COFs with a commendable trade‐off among crystallinity, stability, and functionality.

Published: June 2023

AbstractOxidation reaction is of critical importance in chemical industry, in which the primary O2 activation step still calls for high‐performance catalysts. Here, a newly developed precise locating carbonization strategy for the fabrication of 21 kinds of dual‐metal single‐atom catalysts with N, S co‐coordinated configurations is reported. As is exemplified by CoN3S1/CuN4@NC, systematical characterizations and in situ observations imply the atomic CoN3S1 and CuN4 sites immobilized on N‐doped carbon, over which the remarkable electron redistribution originating from their unsymmetrical coordination configurations. Impressively, the obtained CoN3S1/CuN4@NC exhibits unprecedented capability in O2 activation and enables a spontaneous process through its dynamic configuration, significantly outperforming the CoN4/CuN4@NC and CoN3S1@NC counterparts. Hence, the CoN3S1/CuN4@NC shows attractive performance in domino synthesis of natural flavone and 19 kinds of derivatives from benzyl alcohol, 2'‐hydroxyacetophenone, and corresponding substituted substrates via aerobic oxidative coupling‐dehydrogenation. Detailed reaction mechanisms and molecule behaviors over CoN3S1/CuN4@NC are also investigated through in situ experiments and simulations.

Published: June 2023

AbstractIn a healthcare setting, biofilms are a major source of infection and difficult to eradicate once formed. Nanoparticles (NPs) can be designed to effectively penetrate biofilms to more efficiently either deliver antibiotic drugs throughout the biofilm matrix or elicit inherent antibiofilm activity. Antibacterial cerium oxide (CeO2) NPs were employed as core material and coated with a mesoporous silica shell (MSN) to generate cerium oxide coated mesoporous silica NPs (CeO2@MSN). Detailed studies of NP‐biofilm interactions are required to rationally develop NP platforms to prevent biofilm‐related infections. This work developed and implemented a unique label‐free analysis platform for the real‐time monitoring of bacterial biofilm formation and then assessed the interactions of antibacterial NPs. An analysis platform which allows bacterial biofilms to grow and develop in situ in flow within the multi‐parametric surface plasmon resonance (MP‐SPR) instrument was established. This enabled simultaneous monitoring and detection of biofilm growth phases, structure, and interactions between differentially charged CeO2@MSNs and bacterial biofilms. Positively charged antibacterial NPs (polyethyleneimine functionalized CeO2@MSNs) were found to be the most efficient to penetrate the biofilm. The MP‐SPR analysis platform was shown to be a powerful tool for monitoring biofilm development in real‐time and to analyze biofilm properties and NP‐biofilm interactions.
Using fish hard-part microchemistry and genetics to quantify population impacts of low-use lock-and-dam structures on the Alabama River

Abstract

Objective
We used two approaches, fish hard-part microchemistry and genetics, to quantify effects of low-use lock-and-dam structures on riverine fish movement. Each approach varied in temporal scope, with microchemistry addressing effects within a lifetime and genetics addressing effects across generations.

Methods
Water samples and individuals of two species (Paddlefish Polyodon spathula and Smallmouth Buffalo Ictiobus bubalus) were collected from four river sections that were separated by three low-use lock-and-dam structures on the Alabama River. Quarterly water samples were collected from 15 sites during 2017–2018, and concentrations of Sr, Ba, Mn, Mg, and Ca were quantified using mass spectrometry.

Result
Water elemental signatures were spatially variable but temporally consistent. The Sr:Ca ratios in fish hard parts differed significantly among river sections for both species. Additionally, discriminant function analyses classified fish to their river capture section with accuracy between 55% and 74% for Paddlefish (errors nearly always assigned individuals to adjacent river sections) and 37–47% for Smallmouth Buffalo. Population genetic analyses included fish from each river section, as well as from Alabama River tributaries and a neighboring watershed. Genotyping-by-sequence techniques identified 1,889 and 3,737 single nucleotide polymorphisms postfiltering in Paddlefish and Smallmouth Buffalo, respectively, which we used to estimate population diversity indices and conduct differentiation analyses. Analysis of molecular variance, discriminant analysis of principal components, Bayesian clustering, and pairwise comparisons of FST values indicated no strong evidence for genetic divergence in either species among river sections.

Conclusion
Within-lifespan results based on hard-part microchemistry suggested a potential for population isolation. However, longer-term genetic effects were not apparent, possibly because the life span of these large and relatively long-lived species means that few generations have passed since dam construction, and there could be sufficient mixing or population connectivity to prevent genetic divergence across river sections, particularly at the most downstream structure.
Syringic acid alleviates valproic acid induced autism via activation of p38 mitogen‐activated protein kinase: Possible molecular approach
Authors: Mallan Sudhanshu , Singh Shamsher 
Published: June 2023

AbstractAutism spectrum disorder (ASD) is a multifactorial neurodevelopmental disorder characterized by restrictive and repetitive behavior followed by impairment in social, verbal, and non‐verbal interaction and communication. Valproic acid (VPA) is a well‐known anti‐epileptic drug, but its prenatal exposure to animals causes social impairment, neurotransmitters imbalance, and neuroinflammation with ASD‐like phenotypes. Syringic acid (SA) is a polyphenolic compound with anti‐inflammatory, anti‐apoptotic, antioxidant, and neuromodulator activity. The purpose of study was to investigate the protective effect of Syringic acid (SA) in prenatal VPA‐treated rats through behavioral, neuroinflammation, oxidative stress, neurotransmitters, neuronal integrity, and apoptotic marker. Single dose of VPA was administered 600 mg/kg, i.p. on a gestational day (GD) 12th and SA was administrated from PnD 26th to 54th at the dose of 25, 50, and 100 mg/kg, p.o. On PnD 56th behavioral parameters (Pain sensitivity, open field test, narrow beam walks test and social impairment test) were performed and all animals were sacrificed, and brain tissue was isolated for oxidative stress (GSH, CAT, and LPO), neuroinflammation (TNF‐α and IL‐6) and neurotransmitters (GABA and Glutamate), histopathology (H&E, Nissl), immunohistochemistry (p38 MAPK) analysis. Rat treated with SA dose‐dependently prevented behavioral alteration, restored antioxidant enzymes, neurotransmitters level, decreased neuroinflammatory markers, and improved neuronal integrity. Furthermore, immunohistochemistry confirmed the reduced p38 MAPK marker expression by SA in VPA induced autistic behavior.
Outlining Stakeholder Engagement in a Sustainable Circular Economy
Authors: Heikkinen Anna , Kujala Johanna , Blomberg Annika 
Published: June 2023

AbstractA circular economy is considered one of the most pertinent solutions to contemporary socioeconomic and environmental sustainability challenges, such as climate change, biodiversity loss and resource depletion. The transition from a linear to a circular economy requires the support and participation of various organisations and institutions as well as stakeholders at all levels of society. This edited volume examines the role and importance of stakeholder engagement in a sustainable circular economy from multiple theoretical and practical perspectives. We understand a sustainable circular economy as a pathway to a more environmentally friendly and socially inclusive society and stakeholder engagement as an important tool to catalyse this journey. This volume provides an in-depth, research-based overview of how stakeholder engagement can catalyse the transition towards a sustainable circular economy and foster and support sustainable change. It provides an up-to-date discussion of theoretical and practical advances that is intended for researchers, policymakers and practitioners working on the circular economy.
Coopetition for a Circular Economy: Horizontal Initiatives in Resolving Collective Environmental Challenges
Authors: Harala Linnea , Aarikka-Stenroos Leena , Ritala Paavo 
Published: June 2023

AbstractTo achieve industry-wide circular economy (CE) outcomes, such as material reuse or recycling, competitors need to join forces and enter the paradoxical relationship of coopetition, whereby competitors collaborate. According to the literature, coopetition can benefit sustainability. However, little is known about coopetition for a CE and how competitors, as stakeholders, can engage in resolving collective environmental challenges. This study examines the phenomenon of coopetition for a CE through an extensive multiple-case study from various industries in Finland. The findings indicate that coopetition for a CE can be organised through four distinctive modes of circularity: agreements for industry standards, pre-competitive R&D and knowledge-sharing, platforms, and reverse logistics systems. New industry standards supporting CE are set by engaging competitors in voluntary agreements. It is important to bring stakeholders together for CE-focused pre-competitive R&D and knowledge-sharing projects and networks. In applied and commercial coopetitive arrangements, stakeholder engagement (e.g., third-party coordination) enables cross-industry collaboration for reverse logistics systems, whereas platforms are used to connect stakeholders and match their supply and demand, thus facilitating the development of CE business models. Our chapter contributes to academic and practical discussions on how coopetition for a CE can manifest and how competitors, as stakeholders, can engage in collaboration and contribute to CE goals.
Connecting the Circular Economy and Sustainability: Finnish Stakeholder Perceptions
Authors: Salminen Hanna , Heikkinen Anna , Kujala Johanna 
Published: June 2023

AbstractThe circular economy has been presented as a means to promote ecological, economic, and social sustainability. However, the connection between the circular economy and sustainability remains undefined in both theory and practice. In this chapter, we examine how a circular economy and its connection to sustainability are understood among key stakeholder groups promoting the circular economy in Finland, a forerunner country in sustainable development. Theoretically, we build on circular economy and corporate sustainability literature. Empirically, we conducted an analysis of 26 qualitative interviews with circular economy stakeholders. As a result, we present three categorisations of a sustainable circular economy: a business-centric circular economy, a systemic circular economy, and a regenerative circular economy. Our findings demonstrate that different stakeholder groups at the local, regional, and national levels acknowledge the importance of the circular economy for the promotion of sustainability. Stakeholder views vary in terms of how broadly sustainability is understood and to what extent a circular economy is connected to the promotion of economic, ecological, and social sustainability. The findings call for a dialogue among stakeholders on how the circular economy can promote sustainable development.
Developing Sustainable Partnerships for Circular Economies: A Literature Review
Authors: Eiselein Philippe , Keygnaert Wim , Brabant Karen 
Published: June 2023

AbstractAlthough the circular economy (CE) is considered a systemic and relational phenomenon, literature on the subject still fails to demonstrate an understanding of how stakeholders engage with one another and, therefore, how long-term partnerships are developed in a context focused on sustainability. In this chapter, we conduct a literature review and an in-depth analysis of 59 articles that have been published over the last decade. Taking on the theoretical lens of the quintuple helix model (QHM), we analyse articles from high-impact journals specialising in the circular economy. Through a constant comparison analysis, we identify three building blocks (vision, stakeholders, and processes) and nine underlying enabling mechanisms that are essential to developing sustainable partnerships for circular economies. We also highlight various obstacles that may affect the development of sustainable partnerships. We contribute to the growing body of literature on circular economy stakeholder engagement by taking a multi-actor, multi-level perspective, and provide a checklist for different stakeholders to understand what is needed to engage with one another and collaborate to resolve sustainability issues.
Stakeholder Engagement Mechanisms and Value Creation in Circular Entrepreneurship
Authors: Re Beatrice , Magnani Giovanna 
Published: June 2023

AbstractThis chapter contributes to the circular entrepreneurship literature regarding the empirical analysis of the stakeholder engagement mechanisms in place between small and medium-sized enterprises (SMEs) and their key stakeholders. The context of analysis is circular entrepreneurship, consisting in the processes of formation and exploitation of opportunities to address key environmental challenges and requiring firms to establish close relationships with a series of stakeholders to narrow, slow, and close the resource loops. Through a multiple case study methodology involving four Finnish circular SMEs and their key stakeholders, this chapter investigates how firms engage their stakeholders, and which are the underlying key stakeholder engagement mechanisms leading to value creation. We summarise our findings in a conceptual framework of stakeholder engagement mechanisms in circular entrepreneurship, reflect upon the limits and challenges that stakeholder engagement may have in fostering value creation and circular practices, and suggest avenues for further research.
