Published: December 2022

AbstractLamellar membranes, especially assembled by microporous framework nanosheets, have excited interest for fast molecular permeation. However, the underlying molecular dissolution behaviors on membrane surface, especially at pore entrances, remain unclear. Here, hierarchical metal–organic framework (MOF) lamellar membranes with 7 nm‐thick surface layer and 553 nm‐thick support layer are prepared. Hydrophilic (–NH2) or hydrophobic (–CH3) groups are decorated at pore entrances on surface layer to manipulate wettability, while –CH3 groups on support layer provide comparable, low‐resistance paths. We demonstrate that molecular dissolution behaviors are determined by molecule–molecule and molecule–pore interactions, derived from intrinsic parameters of molecule and membrane. Importantly, two dissolution model equations are established: for hydrophobic membrane surface, dissolution activation energy (ES) obeys ES = Kmln[(γL‐γC)μd2], while turns to ES=Kaln[(γL‐γC)δeμd2] for hydrophilic one. Particularly, hydrophilic pore entrances exert strong interaction with polar molecules, thus compensating the energy consumed by molecule rearrangement, giving fast permeation (>270 L m−2 h−1 bar−1).

AbstractPremiseA major goal of systematic biology is to uncover the evolutionary history of organisms and translate that knowledge into stable classification systems. Here, we integrate three sets of genome‐wide data to resolve phylogenetic relationships in Cornaceae (containing only Cornus s.l.), reconstruct the biogeographic history of the clade, and provide a revised classification using the PhyloCode to stabilize names for this taxonomically controversial group.MethodsWe conducted phylogenetic analyses using 312 single‐copy nuclear genes and 70 plastid genes from Angiosperms353 Hyb‐Seq, plus numerous loci from RAD‐Seq. We integrated fossils using morphological data and produced a dated phylogeny for biogeographical analysis.ResultsA well‐resolved, strongly supported, comprehensive phylogeny was obtained. Biogeographic analyses support an origin and rapid diversification of Cornus into four morphologically distinct major clades in the Northern Hemisphere (with an eastern Asian ancestor) during the late Cretaceous. Dispersal into Africa from eastern Asia likely occurred along the Tethys Seaway during the Paleogene, whereas dispersal into South America likely occurred during the Neogene. Diversification within the northern hemisphere likely involved repeated independent colonization of new areas during the Paleogene and Neogene along the Bering Land Bridge, the North Atlantic Land Bridge, and the Tethys Seaway. Thirteen strongly supported clades were named following rules of the PhyloCode.ConclusionsOur study provides an example of integrating genomic and morphological data to produce a robust, explicit species phylogeny that includes fossil taxa, which we translate into an updated classification scheme using the PhyloCode to stabilize names.
An Efficient and Reversible Singlet Oxygen Quencher for Suppressing Photobleaching of Organic Fluorescent Dyes
Authors: Jiang Rui , Yang En‐lai , Lin Zhen‐zhen , Wang Xu‐dong 
Published: December 2022

AbstractQuenching singlet oxygen is the key to improve photostability of fluorescent dyes. We have systematically studied the capability of a new singlet oxygen quencher, DABCOnium (an alkylated derivative of 1,4‐diazabicyclo[2.2.2] octane) on removing singlet oxygen. Results showed that DABCOnium can significantly enhancing photostability of fluorescent thin films for more than 4.3 times compared with that without DABCOnium. After 2 hours of continuous irradiation, fluorescent film doped with DABCOnium retained 90 % of its original fluorescence intensity, which paves a new way in designing high performance singlet oxygen quenchers.
Market update: Sixty years of change in Papua New Guineaʼs fresh food marketplaces
Authors: Sharp Timothy L. M. , Busse Mark , Bourke R. Michael 
Published: December 2022

AbstractOpen‐air marketplaces are vital to food security, livelihoods, and the national economy in Papua New Guinea (PNG). Over the past 60 years, rapid growth of urban populations, changes in global commodity prices, and the decline in value of the PNG currency have stimulated demand for domestic fresh food. Selling fresh food in marketplaces has also become an attractive way to earn money for rural producers, whose returns on labour on their export crops have declined, and for urban residents struggling to make a living. This in turn has led to significant changes in PNGʼs marketplaces: spatial and temporal changes, changes in what is bought and sold, changes in who is selling, and changes in how food is transacted. In this paper, we bring together research on PNGʼs marketplaces from between 1961 and 2022 to document these changes and their causes, alongside important continuities, and to examine the implications and substantial gaps in our knowledge.
An integrated spatial approach to archaeological prospection using GIS and pedestrian survey data at Tell Abu Shusha, Israel
Authors: Price Seth J. , Adams Matthew J. , Tepper Yotam 
Published: December 2022

AbstractGeographic information systems (GIS) methods, combined with airborne remote sensing, enable collection of complex spatial datasets across broad regional areas. This article explores the use of GIS techniques for fast collection, processing and analysis of pedestrian survey data. This approach is used at Tell Abu Shusha, a multiperiod site in the Jezreel Valley of northern Israel. Surface survey of this tell and the surrounding region, conducted by the Jezreel Valley Regional Project during 2017, documented extensive visible remains of settlement features as well as the ruins of the Ottoman era village of Abu Shusha. Using this data, the potential for existing spatial analytical techniques to be modified and improved through modern processing capabilities is shown. Kolmogorov–Smirnov nonparametric tests, pure locational (k‐means) and unconstrained clustering methods were applied to the field walking survey data, showing evidence of feature clustering at multiple scales as well as environmental patterning in where features are located. Results demonstrate that these approaches increase the speed and accuracy of pedestrian survey data collection and that the modification of these analytical techniques makes them more robust than before, allowing for the identification of meaningful large‐scale spatial patterns.
Gamma‐ray production in supermassive black hole binary OJ 287

Published: December 2022

AbstractOJ 287 is one of the most studied BL Lac objects with very long optical measurements whose spectrum has been well measured through radio to X‐ray band. The most outstanding characteristic of OJ 287 is its 12‐year period, which is discovered in the optical range and has also been confirmed in the X‐ray band. OJ 287 is supposed to be a binary black hole system in which a secondary black hole passes the accretion disk of the primary black hole and produces two impact flashes per period. It has also been proposed to be a GeV–TeV source. Observations of OJ 287 in the GeV–TeV energy range reveal the variable γ‐ray connected with the flare activity of this object. The spectral energy distributions of blazars consist of two broad peaks. The first, lower frequency peak is due to the synchrotron emissions of relativistic electrons in the jet. Leptonic and hadronic emission mechanisms are considered to describe the second, higher frequency spectrum part. The inverse Compton emissions of the same electrons (synchrotron self‐Compton model) or combined with an external Compton mechanism are considered in the leptonic scenario. The last one supposes the existence of the external to jet photon cloud. The high‐energy spectrum part is also supposed to be generated due to the acceleration of the cosmic ray hadrons in shock produced by outflow, which expands and then collides with the wind of the primary black hole. The detection of GeV–TeV energy fluxes can help find the parameters of the configuration of the two‐black hole system.

AbstractCygnus Region contains many objects that are bright in all wavelengths, including one of the most powerful active star formation regions: Cyg OB2, pulsars, and supernova remnants. Some of the sources have been detected at high and very high energies. One of them was discovered due to the proximity to well‐known microquasar Cyg X‐3. It is an object TeV J2032 + 4130. This object is still of unresolved nature and is being intensively studied in different energy ranges. Numerous X‐ray point sources and diffuse X‐ray emission regions were found within the TeV J2032 + 4130 region by Chandra and Suzaku. Intensities detected in X‐rays from these regions may favor a scenario with the dominantly nucleonic, not electronic origin of TeV emission. The results of the 20‐year observations of TeV J2032 + 4130 object by the SHALON experiment are presented. Collected experimental data on fluxes, spectrum shape, and morphology of TeV J2032 + 413 can help determine an object nature.

AbstractTo verify the inhibitory mechanism of β‐catenin‐designed peptides in colorectal cancer(CRC) tumors, the following experiments were performed. In vitro colony formation, Transwell assays, and flow cytometry were performed to assess the biological effects of designed peptides (F18KD, F20A4‐7k, F20A4‐10k, and F20A3‐9k + F20A4‐10k + F20A5‐9k) in HT‐29 cells. In vivo xenograft experiments were performed and treated with peptides. Next, tumors were subjected to Hematoxylin and eosin staining (HE), immunohistochemical, and terminal deoxynucleotidyl transferase dUTP nick end labeling staining assays to evaluate the inhibitory effect of peptides on tumors. β‐Catenin levels were quantified via western blotting (WB) and quantitative real‐time polymerase chain reaction, and β‐catenin was located using confocal laser scanning microscopy. T‐cell factor‐4 (TCF‐4), C‐myc, and CCND1 levels were quantified via WB. Results were obtained as following. First, the peptides reduced viability, migration, and invasion; promoted apoptosis; and stabilized the S phase of HT‐29 cells. Second, peptides suppressed tumor growth and downregulated the expression of CD34, vascular endothelial growth factor, and β‐catenin in tumors. Furthermore, we found that peptides downregulated β‐catenin expression in both the cytoplasm and nucleus; TCF‐4, C‐myc, and CCND1 expression was also downregulated. Notably, β‐catenin‐targeting peptides had a better inhibitory effect on CRC than non‐β‐catenin‐target peptides, and a combination of peptides exerted a more potent inhibitory effect on CRC than single peptides. It suggested that β‐Catenin‐targeting peptides promote apoptosis in CRC tumors by inhibiting activation of the Wnt/β‐catenin pathway.
Alcohol, gender, and violence: Factors influencing blame for partner aggression
Authors: Ross Jody M. , Davis Jedidiah 
Published: December 2022

AbstractAlcohol use has been associated with intimate partner violence (IPV) and reduced perpetrator blameworthiness, but this finding is not universal. Researchers examining alcohol and IPV‐related blame often utilize vignettes depicting perpetrators who are sober and compare this to perpetrators depicted as more or less intoxicated. In this study, participants read one of three vignettes depicting male‐to‐female physical IPV. We compared participants' blame attributions across three conditions: perpetrator sober, perpetrator intoxicated‐infrequent drinker, and perpetrator intoxicated‐frequent drinker. Alcohol did not mitigate perpetrator blameworthiness for the assault; however, only the intoxicated‐frequent drinker was rated as more blameworthy for his violence than the sober perpetrator. Participants also reported their own IPV perpetration, drinking behaviors, and gender role beliefs. Traditional gender role beliefs and a history of IPV perpetration were associated with shifting some of the blame onto the victim, and this was true for both men and women, especially when the perpetrator was described as a frequent drinker. Researchers should consider whether their alcohol vignettes might depict a behavior as reflecting the situation or the drinker's character, as this may impact their results. Furthermore, different observer characteristics may differentially predict blame attribution.

Published: December 2022

AbstractBackgroundObservational epidemiological studies suggest that lung cancer risk may be raised by gastroesophageal reflux disease (GERD); however, the causal relationship between them remains unknown. Our study performed the two‐sample Mendelian randomization (MR) approach to examine the causal relationship between GERD and lung cancer.MethodsInstrument variables were found to be independent single nucleotide polymorphisms (SNPs) that were highly linked with GERD (n = 129,080). Summary data from genome‐wide association studies (GWAS) data were used to determine outcomes for lung cancer (n = 11,348), squamous cell lung cancer (LUSC), and lung adenocarcinoma (LUAD). In this study, three MR statistical techniques (inverse variance weighted (IVW), MR‐Egger, and weighted median) were used to examine the potential causative relationship between GERD and the risk of lung cancer. Cochran's Q test, MR‐Egger intercept test, leave‐one‐out analysis, and the funnel plot were all used in sensitivity analyses.ResultsThe main IVW method revealed that GERD substantially increased the risk of lung cancer [odds ratio (OR) = 1.37; 95% CI 1.16–1.63, p = 0. 0003], which was also supported by weighted median and MR‐Egger analyses. Using IVW estimate, similar causal relationships were also observed between GERD and LUSC (OR = 1.56; 95% CI 1.26–1.93, p = 5.35 × 10−5) and LUAD (OR = 1.45; 95% CI 1.09–1.93, p = 0.01). Although potential heterogeneity was observed in some studies, random effect IVW was not violated by the heterogeneity, indicating that the causal effect was robust.ConclusionGERD was positively associated with the risk of lung cancer, for LUSC and LUAD. This study shed light on a new direction for prevent strategy of lung cancer and therapeutic perspectives in patients with GERD.

AbstractPurification through repeated column chromatography over silica gel and Sephadex LH‐20 of the ethanol extract of the stems of Cissus aralioides (Baker) Planch. resulted in the isolation of a new ceramide, aralioidamide A (1), along with five known compounds (2–6). Their structures were determined by the extensive analyses of their spectroscopic (1D and 2D NMR) and spectrometric data, and comparison with those reported in the literature. Aralioidamide A (1) displayed weak antibacterial activity (MIC=256 μg/mL) against Bacillus subtilis, Staphylococcus aureus and Shigella flexneri and was inactive (MIC>256 μg/mL) against the tested fungi.
Staggered board, social capital and sustainability
Authors: Likitapiwat Tanakorn , Treepongkaruna Sirimon 
Published: December 2022

AbstractMaintaining good relationships with internal and external stakeholders can help companies gain competitive advantages and mitigate risks associated with social factors. However, building social capital is not an easy task, as it requires management to prioritize long‐term goals over short‐term gains. The board of directors is expected to ensure that management maximizes shareholders' value, commits to strengthening its relationship with stakeholders, and engages in socially responsible activities. These expectations depend heavily on the quality and effectiveness of the board. Certain board characteristics may impede its ability to drive long‐term vision or create good stakeholder relationships, leading to a decline in the company's social capital. In this paper, we analyze board characteristics of publicly listed US firms, focusing on staggered boards, and find evidence supporting the agency theory that staggered boards adversely affect firms' social capital. To ensure the robustness of our analysis, we conduct additional analyses including propensity score matching, entropy balancing, and instrumental‐variable analysis.
A novel spectrum handoff switching decision scheme for improved performance of secondary users in cognitive radio network
Authors: Dey Sudipta , Saha Misra Iti 
Published: December 2022

SummarySpectrum handoff (SH) in the cognitive radio network (CRN) is considered as a key challenging area to enhance the performance of secondary users (SUs) in CRN. If the primary user is detected, the SU may pause and stay on the same channel or may perform SH to another idle channel. An accurate and precise handoff decision improves the overall throughput and quality of experience of end‐users. In this paper, we introduce a new SH algorithm and continuous short‐sensing strategy to improve the overall throughput of SUs. In addition, we have derived the minimum length of the target channel sequence based on network‐specific parameters like desired call dropping probability. Further, an optimum channel search time is obtained to minimize the handoff delay. The simulation result shows that the proposed scheme improves the overall throughput of CRN, and the mean opinion score of different video applications increases by 10%, 4.6%, and 1% for rapid motion, gentle walk, and slight motion types of video applications. In the case of VoIP applications, the maximum simultaneous call is improved by 2 times in the case of G.711, 1.72 times in the case of G.729, and 1.66 times in the case of iLBC.

AbstractStütz‐ und Schutzkonstruktionen aus Naturstein zählen zu Standardbauwerken im Straßen‐ und Eisenbahnbau sowie im angrenzenden Ingenieurbau. Dabei wird zwischen unvermörtelten und vermörtelten Steinkonstruktionen unterschieden, wobei bei Letzteren die Fugenausbildung mittels Betonmörtel erfolgt. Diese Ausbildung der Fuge dient zur Verbesserung der Kraftübertragung zwischen den einzelnen Steinen, führt zu einer Reduzierung von Bauwerksverformungen und bringt gegenüber unvermörtelten Konstruktionen insgesamt eine Erhöhung der inneren Standsicherheit mit sich. Durch die Interaktion zwischen Stein und Betonmörtel können Schubkräfte übertragen bzw. aufgenommen werden, die insbesondere einem auftretenden Erddruck entgegenwirken: die Scherparameter Kohäsion (Haftfestigkeit) und Reibungswinkel bauen einen Widerstand gegen mögliche Schubbeanspruchung auf und spielen eine wesentliche Rolle hinsichtlich der Tragfähigkeit derartiger Bauwerke. In dieser Studie wird versucht, mittels experimenteller Laborversuche eine quantitative Abschätzung von Werten für Haftfestigkeit und Reibungswinkel abzuleiten. Darüber hinaus sollen die Eigenschaften von üblicherweise verwendeten Betonmörteln erfasst werden. Übergeordnetes Ziel ist es, Rückschlüsse auf die innere Stabilität derartiger Steinstützkörper zu ziehen und so Grundlagen für die Bemessung von Steinstützkörpern darzulegen.

AbstractAimsWe aimed to identify prognostic individual factors in patients with first acute heart failure (HF) hospitalization, considering both death and readmission as part of the natural history of HF.Methods and resultsWe used data from the observational, prospective, multicentre EPICAL2 cohort study from which we selected incident cases of acute HF alive at discharge. We relied on an illness‐death model to identify prognostic factors on first readmission and on mortality before and after readmission. In 451 patients hospitalized for first acute HF, we observed within the year after discharge, 23 (5.1%) deaths before readmission and 270 (59.9%) first readmissions, of which 60 (22.2%) were followed by death of any cause. First, among patient characteristics, only Charlson index ≥ 8 was associated with first readmission [adjusted hazard ratio (aHR) = 1.6, 95% confidence interval (CI) (1.1–2.3), P = 0.011]. Second, Charlson index ≥ 8 [aHR = 4.2, 95% CI (1.2–14.8), P = 0.025], low blood pressure (BP) [aHR = 12.2, 95% CI (1.9–79.6), P = 0.009], high BP [aHR = 6.9, 95% CI (1.3–36.4), P = 0.023], and prescription of recommended dual or triple HF therapy at index discharge [aHR = 0.2, 95% CI (0.1–0.7), P = 0.014] were associated with mortality before any readmission. Third, Charlson index ≥ 8 [aHR = 2.4, 95% CI (1.1–5.6), P = 0.037] and the time to first readmission (per 30 days additional) [aHR = 1.2; 95% CI (1.1–1.4), P = 0.007] were associated with mortality after readmission.ConclusionsRegardless of the prognostic state considered, we showed that comorbidities are of critical prognostic value in a real‐world cohort of incident HF cases. This argues in favour of multidisciplinary care in HF.

AbstractAmniotic fluid embolism (AFE) is a rare but potentially fatal complication of pregnancy. Prompt and aggressive resuscitative strategies are crucial in promoting survivability. We present a case of AFE resulting in cardiopulmonary collapse and subsequent cardiac arrest where we were able to safely deliver the baby and resuscitate the mother with veno‐arterial extracorporeal membrane oxygenation and Impella CP—a novel combination known as ECPELLA. We discuss the implications of this approach as a more efficacious strategy in resuscitating AFE‐induced cardiogenic shock and arrest.
