Adaptive event‐triggered bipartite consensus control for multi‐agent systems under signed digraphs
Authors: Mu Rui , Wei Airong , Li Haitao , Zhang Xianfu , Duan Zhiyu 
Published: October 2022

AbstractIn this paper, the bipartite consensus problem is addressed via adaptive event‐triggered control for multi‐agent systems in directed communication networks, where cooperative and competitive interactions are considered simultaneously. Under a strongly connected digraph, a novel fully distributed control protocol is first put forward, which consists of an adaptive controller and two event‐triggered mechanisms. The protocol is flexible and capable of achieving bipartite consensus without employing global information. Meanwhile, the Zeno behavior cannot occur by embedding functions in the event‐triggered mechanisms. Furthermore, a general digraph with a spanning tree is investigated, and it is shown that the proposed protocol is still effective in bipartite consensus including the leader–follower one as a special case. It is worth noting that there is no need for the protocol to continuously update the controller, nor to maintain the uninterrupted communication with neighbors. Finally, the validity of the presented results is confirmed by simulations.

Published: October 2022

AbstractThis paper aims to validate the mission‐critical OSS (open‐source software) model acceptance process using a third‐order formative‐formative measuring model. A two‐stage formative‐formative model was used for partial least square analysis. It includes eight primary mission‐critical OSS adoption constructs and three second‐order (technological, organizational, and environmental). Although nomological validity was affirmed, the empirical findings show the absence of multicollinearity. This study will give organizations in critical industries enough information to understand the importance and weight of each component/factor of the mission‐critical OSS adoption model. The coefficient of determination R2 exceeds the minimum threshold (0.750), and all the hypotheses are significant. This study also contributed to the existing literature by identifying those factors that influence mission‐critical OSS adoption, allowing firms in critical sectors to better understand their mission‐critical OSS adoption issues. Cross‐cultural validation across a broad community is proposed to increase the validity and generalization of the sample scales.

AbstractThe Anisian (Middle Triassic) witnessed the diversification of brachiopods after the Permian–Triassic extinction. The Anisian brachiopod fauna from the southern Qilian Mountains in north‐western China has the highest taxonomic diversity at species level among coeval faunas worldwide. Nevertheless, many taxa from this remote region remain poorly defined, and therefore require emendation. Here we describe 23 species (including two uncertain species) in 15 brachiopod genera based on well‐preserved carbonate and silicified specimens collected from the Anisian Dajialian and Qieermagou formations in Tianjun, southern Qilian Mountains. Two new genera (Crenulatomargus, Tianjunospina) and six new species (Costirhynchopsis xui, Crenulatomargus terebratuliformis, Schwagerispira elegans, Lepismatina? inusitata, Tianjunospina junheensis, Qilianoconcha circularis) are erected. The diagnoses of Triasorhynchia, Yangkongia, Sinucostella, Aequspiriferina, Qilianoconcha and Parantiptychia are emended. Also, the genus Eoantiptychia and the family Triasorhynchiidae are regarded as junior synonyms of Qilianoconcha and Tetrarhynchiidae, respectively. After systematic description and taxonomic emendation, 56 species (including seven uncertain species) in 26 genera are confirmed in the southern Qilian brachiopod fauna. Network analysis of 14 brachiopod faunas worldwide shows that six groups were detected during the Anisian (Qingyan, southern Qilian – western Qinling, Himalaya – northern Siberia, central Qinghai, New Zealand, and Europe/western Tethys). Compared with those from the western Tethys, the eastern Tethyan faunas are less allied to each other. Except for the assemblage from the adjacent western Qinling area, other coeval faunas have much lower affinities with the Qilian fauna.

AbstractBackgroundAvian coccidiosis is thought to be one of the most expensive infectious diseases in the poultry industry.ObjectivesSafe and alternative anti‐coccidial drugs are herbal extracts because they do not result in tissue residue and drug resistance. The objective of the present study was to evaluate the anti‐coccidial effect of the herbal mixture, a complex of two plants (Echinacea purpurea, Glycyrrhiza glabra) in broiler chickens in comparison with toltrazuril.MethodsOne hundred twenty broiler chickens were used in this experiment and divided into 4 equally numbered groups. All the groups, except Group D, were experimentally infected with mixed Eimeria spp. (E. Tenella, E. maxima, E. necatrix and E. brunetti) on day 14. Group A treated with an herbal mixture [Glycyrrhiza glabra Extract 5% (standardised to 5.4% glycyrrhizic acid) and Echinacea purpurea Extract 2% (standardised to 4% total phenolic content based on chlorogenic acid); Coxinin‐EC®; Shamim Teb Sepid Giti]. Group B treated with toltrazuril. Group C was experimentally infected with mixed Eimeria spp. but they did not have any treatment, this group was our positive control. Performance indices, faecal oocyst excretion, and intestinal lesion score were determined during the experiment.ResultsPositive control group had the poorest results and more mortality than other groups. Group D was not infected and was healthy all the experiment period. Treatment with herbal complex significantly reduced the negative performance and pathogenic effects associated with Eimeria spp. at a level that was comparable with toltrazuril.ConclusionsIn summary, the anti‐coccidial activity of the studied herbal complex suggests its use as an alternative anti‐coccidial agent to chemotherapeutic drugs for controlling coccidiosis in poultry.Highlights
Coccidiosis is an important infectious disease that causes serious financial loss to the poultry industry.
Chemical anti‐coccidial drugs and vaccines are the main control strategies to combat the disease. However, these tools have some constraints.
Herbal remedies are suitable alternatives to chemical compounds for control of losses associated with coccidiosis in poultry.
An herbal mixture (Echinacea purpurea, Glycyrrhiza glabra) has promising effects for controlling of coccidiosis in broiler chickens.
Climate change in contemporary British and Irish poetry and poetic criticism: Literary representation and environmental activism
Authors: Xie Chao 
Published: October 2022

AbstractMuch ink has been spilt on the study of climate change fiction (cli‐fi), whereas relatively less attention has been devoted to the burgeoning growth of climate change poetry. As a sub‐genre of ecopoetry which aims at dealing with realistic environmental issues and raising readers' awareness to protect the earth, climate change poetry not only represents the ongoing climatic crises in varied ways, be they realistic or imaginative, but also actively engages in provoking ecological responsibilities and environmental activism. This article is an overview of contemporary British and Irish climate change poetry and its literary criticism. Having emerged at the end of the 20th century in the United Kingdom, this poetic genre cuts across literature and environment, rising both as a prominent literary mode and an important environmental phenomenon. Interdisciplinarity, multiple topics, environmental activism, and experimentation are its primary characteristics. Current scholarship on contemporary British and Irish climate change poetry is limited and it mainly adopts theories of ecocriticism and the Anthropocene. Climate justice, poetry and activism, and comparative literary perspective are among promising avenues for the future study of this new poetic genre. Contemporary British and Irish climate change poetry, and its criticism, indicate both poets and critics' efforts to represent and, more importantly, to grapple with ongoing climate change.This article is categorized under:Trans‐disciplinary Perspectives > Humanities and the Creative ArtsClimate, Nature, and Ethics > Ethics and Climate Change
Assessing release strategies for reintroductions of endangered Wyoming toads
Authors: Linhoff Luke J. , Donnelly Maureen A. 
Published: October 2022

AbstractWe performed 3 experimental reintroductions of the critically endangered Wyoming toad (Anaxyrus baxteri) to study the toad's spatial ecology, behavior, and test the effectiveness of a soft‐release strategy at Mortenson Lake National Wildlife Refuge, Wyoming, USA. We tracked reintroduced, captive‐bred toads (n = 46) and field collected toads that had been in the wild for at least one year (n = 12) using a harmonic tracking system totaling 1,438 toad relocations in 2014 and 2015. We compared the spatial ecology and behavior of soft‐released toads, hard‐released toads, and overwintered toads. Hard‐released toads were transported to the reintroduction site and released. Soft‐released toads were kept in an outdoor enclosure at the release site for 14 days before release. Compared to hard‐released toads, the soft‐release group's average total path distance moved was lower (mean difference = 263.23, CI = 115.37 – 411.05, P = 0.007). Additionally, hard‐released toads in the first 2 days post release moved 380% farther than the soft‐released toads in the same 2‐day period. Our results indicated that soft‐releases are an effective way to improve site fidelity and retain wild‐type spatial ecology and behavior of reintroduced captive‐bred amphibians.

Published: October 2022

AbstractThe dibenzyl complex of barium [(Me4TACD)Ba(CH2Ph)2] was prepared by reacting [Ba(CH2Ph)2] with NNNN‐type macrocycle Me4TACD (Me4TACD=1,4,7,10‐tetramethyltetraazacyclododecane) and isolated as yellow crystals. Single crystal X‐ray diffraction revealed η2‐ and η3‐coordination of the benzyl groups. The benzylbarium cation in [(Me4TACD)Ba(CH2Ph)(thf)][B(C6H3‐3,5‐Me2)4] was obtained upon protonolysis of the neutral bariumdibenzyl with the weak Brønsted acid [NEt3H][B(C6H3‐3,5‐Me2)4] and isolated as colorless crystals. When the benzylbarium cation was reacted with H2 (1 bar) in THF at room temperature, colorless crystals of the dinuclear hydride complex [(Me4TACD)2Ba2(μ‐H)2(thf)4][B(C6H3‐3,5‐Me2)4]2 precipitated from the reaction mixture and characterized by single crystal X‐ray diffraction. The structural motif [Ba2(μ‐H)2]2+ was compared with that published in the literature. Hydrogenolysis of the dibenzyl [(Me4TACD)Ca(CH2Ph)2] under the same conditions resulted in decomposition.
How planar superconductors cure their infrared divergences

Published: October 2022

Abstract
Planar superconductors, emerging in thin films with thickness comparable to the superconducting coherence length, differ crucially from their bulk counterparts. Coulomb interactions between charges are logarithmic up to distances comparable to typical sample sizes and the Anderson-Higgs mechanism is ineffective to screen the infrared divergences of the resulting (2+1)-dimensional QED because the Pearl length screening the vortex interactions is also typically larger than the sample size. As a result, the system decomposes into superconducting droplets with the typical size of order of superconducting coherence length. We show that two possible phases of the film match the two known mechanisms for curing the (2+1)-dimensional QED infrared divergences, either by generating a mixed topological Chern-Simons mass or by magnetic monopole instantons. The former mechanism works in superconductors, the latter one governs mirror-dual superinsulators. Planar superconductors are thus described by a topological Chern-Simons gauge (TCSG) theory that replaces the Ginzburg-Landau model in two dimensions. In the TCSG model, the Higgs field is absent. Accordingly, in planar superconductors Abrikosov vortices do not form, and only Josephson vortices without normal core do exist.
Inflammation, sauna bathing, and all-cause mortality in middle-aged and older Finnish men: a cohort study

Published: October 2022

AbstractInflammation and sauna bathing are each related to the risk of all-cause mortality. The interplay between inflammation, sauna bathing and all-cause mortality is not well understood. We aimed to evaluate the separate and joint associations of inflammation (high sensitivity C-reactive protein, hsCRP) and frequency of sauna bathing (FSB) with all-cause mortality in a cohort of Caucasian men. We used the Kuopio Ischaemic Heart Disease Study cohort comprising 2575 men aged 42–61 years at baseline. Serum hsCRP was measured using an immunometric assay and sauna bathing habits were assessed by a self-administered questionnaire. High sensitivity CRP was categorized as normal and high (≤ 3 and > 3 mg/L, respectively) and FSB as low and high (defined as ≤ 2 and 3–7 sessions/week respectively). A total of 1618 deaths occurred during a median follow-up of 27.8 years. Comparing high vs normal hsCRP levels, the multivariable-adjusted HR (95% CI) for all-cause mortality was 1.27 (1.13–1.44). Comparing high vs low FSB, the multivariable-adjusted HR (95% CI) for all-cause mortality was 0.86 (0.76–0.97). Compared with normal hsCRP-low FSB, high hsCRP-low FSB was associated with an increased risk of all-cause mortality 1.28 (1.12–1.47), with no evidence of an association for high hsCRP-high FSB and all-cause mortality risk 1.06 (0.81–1.40). Positive additive and multiplicative interactions were found between hsCRP and FSB in relation to mortality. In a general Finnish male population, both hsCRP and FSB are each independently associated with all-cause mortality. However, frequent sauna baths appear to offset the increased all-cause mortality risk related to high hsCRP levels.

AbstractIn 2015, two oil and gas companies conducted seismic surveys along the northeast coast of Sakhalin Island, Russia, near western gray whale (Eschrichtius robustus) feeding areas. This population of whales was listed as Critically Endangered at the time of the operations described here but has been reclassified as Endangered since 2018. The number and duration of the 2015 seismic surveys surpassed the level of previous seismic survey activity in this area, elevating concerns regarding disturbance of feeding gray whales and the potential for auditory injury. Exxon Neftegas Limited (ENL) developed a mitigation approach to address these concerns and, more importantly, implemented a comprehensive data collection strategy to assess the effectiveness of this approach. The mitigation approach prioritized completion of the seismic surveys closest to the nearshore feeding area as early in the season as possible, when fewer gray whales would be present. This was accomplished by increasing operational efficiency through the use of multiple seismic vessels and by establishing zones with specific seasonal criteria determining when air gun shutdowns would be implemented. These zones and seasonal criteria were based on pre-season modeled acoustic footprints of the air gun array and on gray whale distribution data collected over the previous 10 years. Real-time acoustic and whale sighting data were instrumental in the implementation of air gun shutdowns. The mitigation effectiveness of these shutdowns was assessed through analyzing short-term behavioral responses and shifts in gray whale distribution due to sound exposure. The overall mitigation strategy of an early survey completion was assessed through bioenergetics models that predict how reduced foraging activity might affect gray whale reproduction and maternal survival. This assessment relied on a total of 17 shore-based and 5 vessel-based teams collecting behavior, distribution, photo-identification, prey, and acoustic data. This paper describes the mitigation approach, the implementation of mitigation measures using real-time acoustic and gray whale location data, and the strategy to assess impacts and mitigation effectiveness.

Abstract
During the summer of 2015, four 4D seismic surveys were conducted on the northeastern Sakhalin shelf near the feeding grounds of the Korean-Okhotsk (western) gray whale (Eschrichtius robustus) population. In addition to the seismic surveys, onshore pile driving activities and vessel operations occurred. Forty autonomous underwater acoustic recorders provided data in the 2 Hz to15 kHz frequency band. Recordings were analyzed to evaluate the characteristics of impulses propagating from the seismic sources. Acoustic metrics analyzed comprised peak sound pressure level (PK), mean square sound pressure level (SPL), sound exposure level (SEL), T100%, T90% (the time intervals that contain the full and 90% of the energy of the impulse), and kurtosis. The impulses analyzed differed significantly due to the variability and complexity of propagation in the shallow water of the northeast Sakhalin shelf. At larger ranges, a seismic precursor propagated in the seabed ahead of the acoustic impulse, and the impulses often interfered with each other, complicating analyses. Additional processing of recordings allowed evaluation and documentation of relevant metrics for pile driving, vessel sounds, and ambient background levels. The computed metrics were used to calibrate acoustic models, generating time resolved estimates of the acoustic levels from seismic surveys, pile driving, and vessel operations on a gray whale distribution grid and along observed gray whale tracks. This paper describes the development of the metrics and the calibrated acoustic models, both of which will be used in work quantifying gray whale behavioral and distribution responses to underwater sounds and to determine whether these observed responses have the potential to impact important parameters at the population level (e.g., reproductive success).
Hutchinson’s theorem in semimetric spaces
Authors: Kocsis Mátyás , Páles Zsolt 
Published: October 2022

AbstractOne of the important consequences of the Banach fixed point theorem is Hutchinson’s theorem which states the existence and uniqueness of fractals in complete metric spaces. The aim of this paper is to extend this theorem for semimetric spaces using the results of Bessenyei and Páles published in 2017. In doing so, some properties of semimetric spaces as well as of the fractal space are investigated. We extend Hausdorff’s theorem to characterize compactness and Blaschke’s theorems to characterize the completeness of the fractal space. Based on these preliminaries, an analogue of Hutchinson’s theorem in the setting of semimetric spaces is proved, and finally, error estimates and stability of fractals are established as well.
Patologie mestruali e contraccezione: principi di personalizzazione della scelta terapeutica
Authors: Graziottin Alessandra , Cuccarollo Angela , Franchi Massimo P. , Uccella Stefano 
Published: October 2022

SommarioLe patologie mestruali sono un problema di salute che affligge dal 5 all’80% delle donne, a seconda della specifica patologia considerata e dei diversi studi. Sono rappresentate da alterazioni del ciclo mestruale (alterazioni del ritmo, della quantità e della durata e dismenorrea) e disturbi extra-uterini correlati alla mestruazione, fra i quali rientrano anche le patologie infiammatorie e autoimmunitarie con esacerbazione catameniale. La contraccezione ormonale offre alle donne non solo un importante strumento per evitare gravidanze indesiderate, ma anche un’efficace opzione terapeutica nel trattamento delle patologie mestruali. I contraccettivi ormonali si dividono in metodi a breve durata d’azione (SARCs), quali contraccettivo orale estroprogestinico (COC), contraccettivo orale progestinico (POP), anello vaginale estroprogestinico e cerotto transdermico estroprogestinico, e metodi a lunga durata d’azione (LARCs), quali dispositivi intrauterini medicati al progesterone e impianto sottocutaneo. La combinazione dell’estrogeno e del progestinico in essi contenuto, nonché i differenti dosaggi e le vie di somministrazione, devono essere tenuti in considerazione nella personalizzazione del trattamento, sia al fine di fornire a ogni donna la terapia più adeguata alle sue necessità e ai suoi disturbi, sia in funzione delle specifiche controindicazioni. In questa rassegna analizziamo brevemente le diverse patologie mestruali, proponiamo una panoramica dei diversi contraccettivi ormonali a oggi disponibili sul mercato e riassumiamo le controindicazioni al loro utilizzo.
Modelling effects of type of trees on urban air pollution with a computational fluid dynamics model
Authors: San Jose R. , Perez-Camanyo J. L. 
Published: October 2022

AbstractUrban trees can change (increase and/or decrease) pollutant concentrations and this study assesses the effect of urban trees on main pollutant concentrations in a 1 km by 1 km area, in a high traffic density zone, in Madrid City (Spain) using numerical computational fluid dynamics (CFD) simulations. A real-life experiment was designed for 1 week of June 2017 with a spatial resolution of 5 m. A zone of vegetation in which the dominant species are broadleaf trees was included in the business as usual (BAU) simulation. The second scenario focused on changing the type of tree from broadleaf in the BAU scenario to needleleaf in the so-called ND scenario. The differences between ND simulation and BAU simulation provide information about the effects of the type of tree on the air quality (NO2 and O3) of the area. The results of the simulations show a high sensitivity to changes in the type of tree in urban parks with strong impacts (hot spots) in several areas located several hundreds of meters away of the green park area. The results of these simulations will provide more knowledge on the effects of trees that will have to be taken into account when developing mitigation strategies for atmospheric pollution.
