Semiochemicals from Trichosanthes anguina (Cucurbitaceae) plants influence behavior in Diaphania indica
Authors: Debnath Rahul , Bhattacharyya Bhramar , Koner Anamika , Barik Anandamay 
Published: June 2023

AbstractBackgroundFirst to third instars of Diaphania indica (Saunders) (Lepidoptera: Crambidae) feed on the lower surface of leaves, while fourth and fifth instars gregariously consume leaves of Trichosanthes anguina L. After defoliating, the caterpillar also attacks flowers and fruits of the plant and finally, results in loss of crop yield. Therefore, behavioral responses of D. indica adults were investigated to volatiles from undamaged (UD), insect‐damaged (ID, plants after feeding by D. indica larvae) and jasmonic acid (JA) treated T. anguina plants.ResultsFemales showed attraction to volatiles of UD and ID plants of three T. anguina cultivars [MNSR‐1 (MNS), Baruipur Long (BAR) and Polo No. 1 (POLO)] in Y‐tube olfactometer bioassays. Females did not show significant negative responses from volatiles of JA treated plants. Females were more attracted to volatiles of ID plants than UD plants. Females showed attraction to volatiles of UD or ID plants compared to JA treated plants. Females were attracted to certain synthetic blends resembling volatiles of insect‐damaged MNS, BAR and POLO plants in olfactometer bioassays. Females could not distinguish among these three certain synthetic blends in olfactometer bioassays. A synthetic blend of 3Z‐hexen‐1‐ol, α‐pinene, hexyl acetate, benzyl alcohol and 6Z‐nonenal at mole ratios of 1.47:1.20:1:1.82:1.21 was prepared at 20 mg/mL dichloromethane and 100 μL when used as lure in funnel traps resulted in the capture of the highest number of D. indica adults in field trails.ConclusionThe earlier five‐component chemical lure could be used in traps in an integrated pest management program of the insect pest, D. indica. © 2023 Society of Chemical Industry.
Basis set customization for modeling noncovalent interactions
Authors: Alenaizan Asem 
Published: June 2023

AbstractIn this article, a simple approach is proposed to reduce the basis set requirement for computing accurate interaction energies for bimolecular noncovalent complexes. A distributed multipole expansion is used to estimate the importance of basis functions in a given atom. Moderate truncation of basis sets results in reduced computational cost without compromising the accuracy. The approach was found fruitful for wavefunction‐based methods and density functional theory approximation using the Dunning, Karlsruhe, and Jensen basis sets.
Spin‐tautomery of endohedral Y@C60 complex
Authors: Semenov Sergey G. , Bedrina Marina E. , Andreeva Tatiana A. , Titov Anatoly V. 
Published: June 2023

AbstractNew conception of spin‐tautomery was developed based on the results of quantum chemical investigation of the endohedral Y@C60 complex. The embedding energies of yttrium into the fullerene cavity, dipole moments, polarizabilities, and IR spectra in the doublet and quartet spin states were calculated by the density‐functional theory quantum chemical methods. The degeneracy degree of the state of the complex is retained upon doublet–quartet excitation, since a twofold increase in the number of electron spin projections is compensated by a twofold decrease in the number of equivalent potential energy minima. The non‐conservation of spin by an endohedral complex with a heavy atom makes it possible to interpret the interconversion of doublet and quartet states as a non‐degenerate spin‐tautomery.
Optimizing Sieving Effect for CO2 Capture from Humid Air Using an Adaptive Ultramicroporous Framework
Authors: Song Danhua , Jiang Feilong , Yuan Daqiang , Chen Qihui , Hong Maochun 
Published: June 2023

AbstractExcessive CO2 in the air can not only lead to serious climate problems but also cause serious damage to humans in confined spaces. Here, a novel metal–organic framework (FJI‐H38) with adaptive ultramicropores and multiple active sites is prepared. It can sieve CO2 from air with the very high adsorption capacity/selectivity but the lowest adsorption enthalpy among the reported physical adsorbents. Such excellent adsorption performances can be retained even at high humidity. Mechanistic studies show that the polar ultramicropore is very suitable for molecular sieving of CO2 from N2, and the distinguishable adsorption sites for H2O and CO2 enable them to be co‐adsorbed. Notably, the adsorbed‐CO2‐driven pore shrinkage can further promote CO2 capture while the adsorbed‐H2O‐induced phase transitions in turn inhibit H2O adsorption. Moreover, FJI‐H38 has excellent stability and recyclability and can be synthesized on a large scale, making it a practical trace CO2 adsorbent. This will provide a new strategy for developing practical adsorbents for CO2 capture from the air.
A New Structure with Localized sp2 Bonding for Fivefold Twinning in Diamond

Published: June 2023

AbstractChanges in atomic bonding configuration in carbon from sp3 to sp2 are known to exist in certain structural defects in diamond, such as twin boundaries, grain boundaries, and dislocations, which have a significant impact on many properties of diamond. In this work, the atomic structure of fivefold twinning in detonation synthesized ultra‐dispersed diamonds is investigated using a combination of techniques, including spherical aberration‐corrected high‐resolution electron microscopy (HREM), HREM image simulations, and molecular mechanics (MM) calculations. The experimental HREM images reveal clearly that the fivefold twinning in diamond has two distinct structures. In addition to the concentric fivefold twins, where the core structure is the intersection of five {111} twinning boundaries, a new extended core structure with co‐hybridization of bonding is identified and analyzed in fivefold twinning. The atomic structure forming these fivefold twinning boundaries and their respective core structures is proposed to involve both the tetrahedral sp3 and planar graphitic sp2 bonding configurations, in which a co‐hybridized planar hexagon of carbon serves as a fundamental structural unit. The presence of this sp2‐bonded planar unit of hexagonal carbon rings in general grain boundaries is also discussed.

Published: June 2023

AbstractLight‐emitting diodes (LEDs) based on colloidal quantum‐dots (QDs) such as CdSe, InP, and ZnSeTe feature a unique advantage of narrow emission linewidth of ≈20 nm, which can produce highly accurate colors, making them a highly promising technology for the realization of displays with Rec. 2020 color gamut. With the rapid development in the past decades, the performances of red and green QLEDs have been remarkably improved, and their efficiency and lifetime can almost meet industrial requirements. However, the industrialization of QLED displays still faces many challenges; for example, (1) the device mechanisms including the charge injection/transport/leakage, exciton quenching, and device degradation are still unclear, which fundamentally limit QLED performance improvement; (2) the blue performances including the efficiency, chromaticity, and stability are relatively low, which are still far from the requirements of practical applications; (3) the color patterning processes including the ink‐jet printing, transfer printing, and photolithography are still immature, which restrict the manufacturing of high resolution full‐color QLED displays. Here, the recent advancements attempting to address the above challenges of QLED displays are specifically reviewed. After a brief overview of QLED development history, device structure/principle, and performances, the main focus is to investigate the recent discoveries on device mechanisms with an emphasis on device degradation. Then recent progress is introduced in blue QLEDs and color patterning. Finally, the opportunities, challenges, solutions, and future research directions of QLED displays are summarized.
Emerging market multinational corporations' cross‐border mergers and acquisitions and political distance: Does corporate political activity matter?
Authors: Brown Lee Warren , Liou Ru‐Shiun , Hasija Dinesh 
Published: June 2023

AbstractDue to rising anti‐globalization sentiment, emerging market multinational corporations (EMNCs) face additional challenges in conducting cross‐border mergers and acquisitions, particularly in the developed markets. Built on institutional theory, we specifically examine how political distance, representing host–home country differences in various attributes in the political environment, influences the speed of approval for EMNC acquisition in the United States. The findings suggest that a larger political distance between the United States and EMNCs home country reflects challenges for EMNCs to gain legitimacy in the United States, resulting in the longer time required for acquisition approval. The EMNCs' corporate political activity moderated this relationship in that more corporate political activity improves the legitimacy perception of EMNCs among political actors, decreasing the time required for acquisition approval.
Green chemistry: Developments and perspectives for sample treatment in forensic methodologies

Published: June 2023

AbstractIn recent years, the environmental implications of advancements in various scientific fields, including analytical chemistry, have become a subject of increasing concern. As a result, the concept of “Green Analytical Chemistry” has been developed, comprising a set of practices designed to reduce the use of toxic chemicals. In the field of analytical, minimizing chemical usage presents a significant challenge, as several sample preparation methods inherently require the utilization of large quantities of solvents. However, this challenge can be addressed through the implementation of both single and combined strategies. One of these strategies is the miniaturization of methods applying the principles of classic liquid–liquid and solid phase extractions in a smaller scale of reagents and samples. In addition, the conventional reagents used in sample preparation can be replaced with green solvents and sorbents. The utilization of miniaturized techniques in forensic toxicology has been widely adopted. Despite this, there remain numerous unexplored applications due to the vast diversity of analytes and biological matrices available. Therefore, implementing green chemistry practices can provide numerous benefits, including enhanced worker safety, reduced waste, and cost savings.This article is categorized under:

Enablers of a Circular Economy: A Strength-Based Stakeholder Engagement Approach
Authors: Lehtimäki Hanna , Kujala Johanna , Thatchenkery Tojo 
Published: June 2023

AbstractRecent circular economy research has emphasised that stakeholder engagement and mutual support of stakeholders are needed to implement the idea of a circular economy. While stakeholder engagement is often considered as something positive, a deeper understanding of what constitutes the positive in stakeholder relationships is needed. The purpose of this chapter is to increase our understanding of strength-based stakeholder engagement as an enabler of the sustainability transition to a circular economy. We explore what constitutes positive and constructive stakeholder relationships at the individual, organisational and societal levels of stakeholder engagement. We present an empirical study of specialists representing different stakeholders involved in advancing the circular economy in Finland. Drawing on a strength-based approach, our study contributes to the stakeholder literature by elucidating the positive foundation of stakeholder engagement. Our study shows that identifying and enhancing the strengths in stakeholder engagement reveals opportunities that exist for a circular economy.
In the Margins of Stakeholder Engagement: Fringe Stakeholders’ Inclusion in Sustainability Transition Initiatives
Authors: Lyra Mariana Galvão , Lehtimäki Hanna 
Published: June 2023

AbstractIn this paper, we examine fringe stakeholders in the context of transitions towards sustainability. Fringe stakeholders refer to marginalised and non-collaborative stakeholders whose voices are not easy to account for. Our conceptual study integrates extant knowledge about the concept of fringe stakeholders to provide valuable insights into studying fringe stakeholders in sustainability transitions. We discuss challenges to addressing fringe stakeholders in the multi-stakeholder approach and draw lessons for research design from a review of empirical studies of fringe stakeholders in sustainability transitions in urban settings. Finally, we discuss the methodological features that enhance giving voice to fringe stakeholders in stakeholder engagement research. As a contribution to research on stakeholder engagement, our paper presents insights related to addressing fringe stakeholders in the contexts of theoretical framing, research design and methodology.
Engaging Stakeholders in the Circular Economy: A Systematic Literature Review
Authors: Oberholzer Silvan , Sachs Sybille 
Published: June 2023

AbstractStakeholder networks in the circular economy (CE) address sustainable production and consumption within a regenerative system. Thus, studying stakeholder interactions within these networks provides essential insight into action urgently required to help businesses foster more harmony between human activity and nature. However, management literature on CE lacks an appropriate analytical lens on stakeholder engagement. To overcome this gap, we conducted a systematic literature review that integrated qualitative content analysis of management research on CE to untangle the complexity of stakeholder interactions in CE. We identify specific aims, activities, and impacts of stakeholder engagement in CE according to their moral, strategic, and pragmatic components. Pragmatic stakeholder engagement dominates our sample, but the research illustrates that embracing moral and strategic stakeholder engagement is equally vital to leveraging stakeholder relationship synergies in CE. Our categorisation of stakeholder engagement in CE provides an overview for researchers and managers and points to the value of the underlying stakeholder network logic for collaboratively addressing environmental challenges such as climate change and biodiversity loss. Correspondingly, we enhance understanding of the intersection of stakeholder engagement with CE management literature and provide an agenda for future research.
How to Engage Stakeholders in Circular Economy Ecosystems: The Process
Authors: Kaipainen Jenni , Uusikartano Jarmo , Aarikka-Stenroos Leena , Harala Linnea , Alakerttula Johanna , Pohls Eeva-Leena 
Published: June 2023

AbstractAchieving a circular economy (CE) requires collaboration between diverse stakeholders, which often happens in socio-technical ecosystem settings, where complementary stakeholders can pursue the system-level goal of improving circularity. The stakeholders, as well as the ecosystem settings in which they collaborate, are diverse, which might impact the process of how stakeholders can be engaged in the CE goals. Thus, to achieve CE goals, different stakeholder engagement processes are needed in different ecosystem settings. Bringing together stakeholder engagement, the ecosystem approach, and CE research as our theoretical background, we address the considerable lack of empirical case research on stakeholder engagement processes by analysing six critical topical CE ecosystem cases in Finland: two at the regional level (a local environmental issue and an industrial collaboration), three at the national level (nutrient recycling, the construction sector, and beverage packaging recycling), and one at the global level (a sustainable fast-food business). Based on a detailed case analysis, we conceptualised four stakeholder engagement process archetypes to achieve CE goals. We propose a model that shows how stakeholders are engaged in different CE ecosystem settings depending on the ecosystem structure and the alignment of stakeholder interests with achieving the CE system-level goal. The model and archetypes contribute to the theory and can benefit organisations and managers engaging stakeholders in emerging or established CE ecosystems.
C and CP violation in effective field theories
Authors: Akdag Hakan , Kubis Bastian , Wirzba Andreas 
Published: June 2023

AbstractThe quest for new sources of the simultaneous violation ofCandCPsymmetry was popular in the 1960s and has since been mostly neglected for more than half a century. In this work we revisit fundamental quark-level operators that breakCandCPup to and including mass dimension 8 for flavor-conserving transitions, relying on the complete operator sets of the so-called Standard Model effective field theory and the low-energy effective field theory. With the formalism of chiral perturbation theory, we match these quark operators to light-meson physics, deriveC- andCP-odd Lagrangians for several processes in theη,η', and pion sectors, and furthermore, as a proof of principle, give estimates for the respective observables in explicit dependence of the underlying high-energy scale for new physics.
Q-lump scattering
Authors: Sutcliffe Paul 
Published: June 2023

Abstract
Q-lumps are spinning planar topological solitons with stationary solutions that satisfy first-order Bogomolny equations. Q-lump scattering has previously been studied only in the charge two sector, by approximating time evolution by motion in the moduli space of stationary solutions. In this paper, higher charge scattering is studied via motion on families of 4-dimensional submanifolds of moduli space, obtained by imposing cyclic symmetries. The results are shown to be in good agreement with field theory simulations, which are then applied to study more complicated Q-lump scattering processes, including examples where the moduli space approximation is not applicable. A variety of exotic scattering events are presented.

Abstract
Objective:
To evaluate the influence of quantitative reports (QReports) on the radiological assessment of hippocampal sclerosis (HS) from MRI of patients with epilepsy in a setting mimicking clinical reality.
Methods: The study included 40 patients with epilepsy, among them 20 with structural abnormalities in the mesial temporal lobe (13 with HS). Six raters blinded to the diagnosis assessed the 3T MRI in two rounds, first using MRI only and later with both MRI and the QReport. Results were evaluated using inter-rater agreement (Fleiss’ kappa $$k$$
k
) and comparison with a consensus of two radiological experts derived from clinical and imaging data, including 7T MRI.

Results:
For the primary outcome, diagnosis of HS, the mean accuracy of the raters improved from 77.5% with MRI only to 86.3% with the additional QReport (effect size $$d=1.43$$

d
=
1.43

). Inter-rater agreement increased from $$k=0.56$$

k
=
0.56

to $$k=0.72$$

k
=
0.72

. Five of the six raters reached higher accuracies, and all reported higher confidence when using the QReports.

Conclusion:
In this pre-use clinical evaluation study, we demonstrated clinical feasibility and usefulness as well as the potential impact of a previously suggested imaging biomarker for radiological assessment of HS.
Simulation der Letalität nach verschiedenen Ex-ante- und Ex-post-Triage-Verfahren bei Menschen mit Behinderungen und Vorerkrankungen

Published: June 2023

ZusammenfassungDer stetige Anstieg an zu behandelnden Patienten während der COVID-19-Pandemie hat das Gesundheitssystem vor eine Vielzahl an Herausforderungen gestellt. Die Intensivstation ist einer der in diesem Zusammenhang besonders stark betroffenen Bereiche. Nur durch umfangreiche Infektionsschutzmaßnahmen sowie einen enormen logistischen Aufwand konnten in Deutschland selbst in Hochphasen der Pandemie die Behandlung aller Intensivpatienten ermöglicht und eine Triage auch in Regionen mit hohem Patientendruck bei gleichzeitig geringen Kapazitäten verhindert werden. Im Hinblick auf die Pandemievorsorge hat der Deutsche Bundestag ein Gesetz zur Triage verabschiedet, das eine Ex-post-Triage explizit untersagt. Bei einer Ex-post-Triage werden auch Patienten, die bereits auf der Intensivstation behandelt werden, in die Triage-Entscheidung einbezogen und Behandlungskapazitäten nach individueller Erfolgsaussicht verteilt. In der Literatur finden sich rechtliche, ethische und soziale Überlegungen zur Triage bei Pandemien, eine quantitative Bewertung im Hinblick auf verschiedene Patientengruppen auf der Intensivstation gibt es hingegen nicht. Der Fokus der Arbeit liegt auf dieser Forschungslücke, und es wird eine quantitative simulationsbasierte Evaluation von Ex-ante- und Ex-post-Triage-Politiken unter Berücksichtigung von Überlebenswahrscheinlichkeiten, Beeinträchtigungen und Vorerkrankungen durchgeführt. Die Ergebnisse zeigen, dass eine Anwendung von Ex-post-Triage, basierend auf Überlebenswahrscheinlichkeiten in allen Patientengruppen, zu einer Reduktion der Mortalität auf der Intensivstation führt. In dem Szenario, das der realen Situation wohl am nächsten kommt, wird eine Reduktion der Mortalität auf der Intensivstation um ca. 15 % schon bei einer einmaligen Anwendung der Ex-post-Triage erreicht. Dieser mortalitätsreduzierende Effekt ist umso größer, je mehr Patienten auf eine intensivmedizinische Behandlung warten.

Abstract
Purpose
This study examines the association between mental health problems in adolescence and general practice (GP) costs during adulthood up to age 50 in the UK.

Methods
We conducted secondary analyses of three British birth cohorts (individuals born in single weeks in 1946, 1958 and 1970). Data for the three cohorts were analysed separately. All respondents who participated in the cohort studies were included. Adolescent mental health status was assessed in each cohort using the Rutter scale (or, for one cohort, a forerunner of that scale) completed in interviews with parents and teachers when cohort members were aged around 16. Presence and severity of conduct and emotional problems were modelled as independent variables in two-part regression models in which the dependent variable was costs of GP services from data collection sweeps up to mid-adulthood. All analyses were adjusted for covariates (cognitive ability, mother's education, housing tenure, father's social class and childhood physical disability).

Results
Adolescent conduct and emotional problems, particularly when coexisting, were associated with relatively high GP costs in adulthood up to age 50. Associations were generally stronger in females than males.

Conclusion
Associations between adolescent mental health problems and annual GP cost were evident decades later, to age 50, suggesting that there could be significant future savings to healthcare budgets if rates of adolescent conduct and emotional problems could be reduced.
