Published: August 2023

AbstractPyrolytic carbon (PyC) interphase plays a crucial role in the mechanical properties of fiber‐reinforced ceramic matrix composites. In this research, a novel micro‐stack PyC interphase with different PyC textures was designed and fabricated by changing the deposition parameters during the chemical vapor infiltration process. The growth mechanism of the micro‐stack PyC interphase with different texture were also studied by experimental characterizations and kinetic calculations, and the results show that the content ratio of (C2H2 + C2H4) to C6H6 gas intermediate is a key parameter to control the texture types of PyC interphase. Furthermore, the value of orientation angle (OA) value, thickness, and modulus of the micro‐stack PyC interphase were further characterized by high resolution TEM (HRTEM), scanning electronic microscopy, and nanoindentation. Finally, the tensile testing of mini‐Cf/PyC/SiC composites was conducted, and the results showed that the tensile strength of mini‐Cf/PyC/SiC composites with micro‐stack PyC interphase is approximately 40% higher than that containing single high texture PyC interphase. The improvements on the tensile strength of Cf/PyC/SiC composites prove the significant advantages of micro‐stack PyC interphase.
A prediction of the thermodynamic, thermophysical, and mechanical properties of CrTaO4 from first principles

Published: August 2023

AbstractIt is reported that the self‐forming CrTaO4 oxide scale can protect refractory high‐entropy alloys from oxidation, superior to Cr2O3. In this paper, the phase stability, mechanical, and thermal properties of three polymorphous phases of CrTaO4 are systematically investigated from first‐principles density functional theory calculations. The mechanical properties predicted using the strain–energy methods indicated that all three phases are mechanically stable. The temperature dependence of elastic constants and polycrystalline moduli of three phases demonstrated the thermal softening as temperature increase. The Helmholtz‐free energies as a function of volume and temperature are derived from phonon dispersions within the quasi‐harmonic approximation at six strained volumes. The calculated apparent bulk coefficients of thermal expansion of these three phases are evaluated, the highest value approximately 13.4× 10−6 K−1 within a temperature range of 500–2000 K for the rutile I41md phase. The lattice thermal conductivity calculated by the Debye–Callaway model suggested that the rutile type I41md phase has the lowest value of approximately 2.1 W/m/K at 1800 K. The other two phases, C2/m and P2/c, exhibit higher values due to relatively lower Grüneisen parameters and larger phonon velocities. The melting point of CrTaO4 is predicted to be between 1975 and 2449 K using ab initio molecular dynamics simulations. This work provides a comprehensive theoretical understanding of the thermodynamic, mechanical, and thermal properties for the new material CrTaO4 and serves as an example of a viable computational design strategy for improved oxidation resistance of refractory alloys at high temperatures.

AbstractIntroductionCurrent delivery tools were not designed for left bundle branch area pacing (LBBAP). Challenges using these tools include lack of reach into the right ventricle and poor support for the lead to penetrate the interventricular septum. Concerns using stylet‐driven leads (SDL) for LBBAP have been previously highlighted. Knowledge and the technical know‐how of using SDL for LBBAP need to be evaluated in a fair and consistent manner. A stepwise approach is devised for use of Agilis HisProTM steerable catheter with Tendril STS Model 2088TC lead for LBBAP and evaluated for safety and reproducibility.MethodsConsecutive patients undergoing LBBAP using the stepwise approach with Agilis HisProTM steerable catheter were analyzed. The safety, efficacy and reproducibility of the technique were evaluated. The lead parameters were analyzed in the immediate (1 day) and short‐term period (3‐6 months) post implantation.ResultsLBBAP was attempted in 41 patients using the stepwise approach of which 37 (90.7%) were successful. The lead parameters were stable in the immediate and short‐term post implantation in all our patients. There was no significant difference between the group of patients with multiple repositioning of the lead compared to those successful at the 1st attempt. There were no acute or short‐term lead and procedural complications.ConclusionA stepwise and systematic approach using the Agilis HisProTM steerable catheter and proper handling of the Tendril STS Model 2088TC stylet‐driven lead is an important part of the armamentarium to deliver LBBAP in a practical, effective and reproducible manner.

AbstractTo investigate the existence of any association between new putative periodontal pathogens and periodontitis. Two independent reviewers conducted electronic literature searches in the MEDLINE (PubMed), EMBASE, DOSS and Google Scholar databases as well as a manual search to identify eligible clinical studies prior to November 2022. Studies comparing the prevalence of microorganisms other than the already‐known periodontal pathogens in subgingival plaque and/or saliva samples between subjects with periodontitis and subject with periodontal health were included. Meta‐analyses were performed on data provided by the included studies. Fifty studies including a total of 2739 periodontitis subjects and 1747 subjects with periodontal health were included. The Archaea domain and 25 bacterial species (Anaeroglobus geminatus, Bacteroidales [G‐2] bacterium HMT 274, Desulfobulbus sp. HMT 041, Dialister invisus, Dialister pneumosintes, Eubacterium brachy, Enterococcus faecalis, Eubacterium nodatum, Eubacterium saphenum, Filifactor alocis, Fretibacterium sp. HMT 360, Fretibacterium sp. HMT 362, Mogibacterium timidum, Peptoniphilaceae sp. HMT 113, Peptostreptococcus stomatis, Porphyromonas endodontalis, Slackia exigua, Streptococcus gordonii, Selenomonas sputigena, Treponema amylovorum, Treponema lecithinolyticum, Treponema maltophilum, Treponema medium, Treponema parvum and Treponema socranskii) were found to be statistically significantly associated with periodontitis. Network studies should be conducted to investigate the role of these newly identified periodontitis‐associated microorganisms through interspecies interaction and host‐microbe crosstalk analyses.

ObjectivesTo evaluate the efficacy of subcutaneous administration of dexmedetomidine/atipamezole at the Governing Vessel 20 (GV20) acupuncture point compared with other administration routes (intramuscular and intravenous) in dogs presented for orthopaedic radiographs.Materials and MethodsProspective, randomised, blinded, controlled clinical study. Sixty‐four client‐owned dogs were randomly injected with 200 μg/m2 of dexmedetomidine intramuscular (lumbar muscles) (n=20), intravenous (n=23) or subcutaneous at the GV20 point (n=21). Following radiographs, dogs received 2000 μg/m2 of atipamezole intramuscular (n=31), or subcutaneous at the GV20 point (n=27). Degree and time to sedation and recovery were assessed using a sedation scale and a Dynamic and Interactive Visual Analog Scale (DIVAS). Clinical physiological variables and adverse events were used. Statistical linear mixed‐effect models (analysis of variance) and Cox models were performed. Significance was set at P‐value <0.05.ResultsSedation was insufficient to perform orthopaedic radiographs in six dogs in the intramuscular group. The time to sedation was significantly longer, and sedation scale and DIVAS scores were significantly lower in the intramuscular group. The intravenous group had significantly higher sedation scale and DIVAS scores than the GV20 group. No significant differences were observed between the intramuscular and GV20 recovery groups, although the time effect was significantly more pronounced in the GV20 recovery group.Clinical SignificanceSubcutaneous administration of dexmedetomidine and atipamezole at GV20 provided effective sedation and recovery in dogs undergoing orthopaedic radiographic studies. GV20 administration provided a clinically similar level of sedation to the intravenous route, and greater and faster sedation and similar recovery to intramuscular.
Face mask mandates: Unilateral authority and gubernatorial leadership in US states

Published: August 2023

AbstractDuring the first year of the COVID‐19 pandemic in the United States, the coordination and cooperation between the federal government and the states failed. American governors were thus tasked with making critical public health policy choices—under extreme uncertainty—with varying institutional capacities, partisan pressures, and state demographic differences. Yet most of the nation's governors chose to impose a face covering or mask mandate to limit the spread of cases. We collected each governor's executive order that mandated the conditions under which their residents would be required to wear a mask and employed a sentiment analysis program to extract key qualities of crisis leadership communication. Our analyses provide insights into the institutional and partisan factors that determined a face mask mandate as well as the institutional, demographic, and leadership communication qualities that affected the total number of cases per capita in the states. Our findings have important implications for post‐pandemic policy recommendations with respect to the effectiveness of policies that seek to lower the transmission of viruses in public spaces and the characteristics of impactful public health messaging by government leaders.

SummaryA novel metabolomics analysis technique, termed matrix‐assisted laser desorption/ionization mass spectrometry imaging‐based plant tissue microarray (MALDI‐MSI‐PTMA), was successfully developed for high‐throughput metabolite detection and imaging from plant tissues. This technique completely overcomes the disadvantage that metabolites cannot be accessible on an intact plant tissue due to the limitations of the special structures of plant cells (e.g. epicuticular wax, cuticle and cell wall) through homogenization of plant tissues, preparation of PTMA moulds and matrix spraying of PTMA sections. Our study shows several properties of MALDI‐MSI‐PTMA, including no need of sample separation and enrichment, high‐throughput metabolite detection and imaging (>1000 samples per day), high‐stability mass spectrometry data acquisition and imaging reconstruction and high reproducibility of data. This novel technique was successfully used to quickly evaluate the effects of two plant growth regulator treatments (i.e. 6‐benzylaminopurine and N‐phenyl‐N′‐1,2,3‐thiadiazol‐5‐ylurea) on endogenous metabolite expression in plant tissue culture specimens of Dracocephalum rupestre Hance (D. rupestre). Intra‐day and inter‐day evaluations indicated that the metabolite data detected on PTMA sections had good reproducibility and stability. A total of 312 metabolite ion signals in leaves tissues of D. rupestre were detected, of which 228 metabolite ion signals were identified, they were composed of 122 primary metabolites, 90 secondary metabolites and 16 identified metabolites of unknown classification. The results demonstrated the advantages of MALDI‐MSI‐PTMA technique for enhancing the overall detection ability of metabolites in plant tissues, indicating that MALDI‐MSI‐PTMA has the potential to become a powerful routine practice for high‐throughput metabolite study in plant science.
Enhanced meristem development, tolerance to oxidative stress and hyposensitivity to nitric oxide in the hypermorphic vq10‐H mutant in AtVQ10 gene
Authors: Gayubas Beatriz , Castillo Mari‐Cruz , Ramos Sara , León José 
Published: August 2023

AbstractNitric oxide (NO) and reactive oxygen are common factors in multiple plant responses to stress, and their involvement in hypoxia‐triggered responses is key to ensure growth under adverse environmental conditions. Here, we analyse the regulatory functions exerted by hypoxia‐, NO‐ and oxidative stress‐inducible Arabidopsis gene coding for the VQ motif‐containing protein 10 (VQ10). A hypermorphic vq10‐H mutant allowed identifying VQ10‐exerted regulation on root and shoot development as well as its role in regulating responses to NO and oxidative stress. Enhanced VQ10 expression in vq10‐H plants led to enhanced elongation of the primary root, and increased root cell division and meristem size during early postgermination development. In shoots, VQ10 activation of cell division was counteracted by WRKY33‐exerted repression, thus leading to a dwarf bushy phenotype in plants with enhanced VQ10 expression in a wrky33 knock‐out background. Low number of differentially expressed genes were identified when vq10‐H versus Col‐0 plants were compared either under normoxia or hypoxia. vq10‐H and VQ10ox plants displayed less tolerance to submergence but, in turn, were more tolerant to oxidative stress and less sensitive to NO than wild‐type plants. VQ10 could be a node integrating redox‐related regulation on development and stress responses.
Gibbsiella quercinecans, a pathogen with an increasing prevalence: A study on the causative agents of bacterial canker of Persian walnut and oak trees in central provinces of Iran
Authors: Firouzianbandpey Saman , Khodaygan Pejman 
Published: August 2023

AbstractThe cultivation of Persian walnuts in Iran is concentrated in the mountainous regions of Zagros and Alborz, encompassing Kohgiluyeh and Boyer‐Ahmad, Isfahan and Fars provinces. Historically, these areas were renowned for their abundant growth of oak trees. However, due to environmental stressors, oak populations in the Zagros region have been declining, leading to an increased risk of diseases caused by new and aggressive pathogens, exacerbated by climate change. Understanding the distribution and association of pathogenic bacteria in the environment, especially for less common or uncommon species, has become crucial. In this study, 80 bacterial strains were isolated from 84 symptomatic walnut and 16 symptomatic oak trees to investigate bacterial canker agents in primary walnut cultivation regions of Iran. Following the hypersensitivity test and pathogenicity assays, 21 strains were classed as ‘Brenneria nigrifluens’ or ‘Brenneria‐like’, based on their similarities to the reference strain B. nigrifluens ICMP 20120 using phenotypic techniques and specific primers (F1/C3, B. nigrifluens). Varying biochemical characteristics were exhibited by the ‘Brenneria‐like’ group in comparison to the ‘B. nigrifluens’ group. Multilocus sequence analysis was performed using the gyrB, rpoB, infB and atpD genes to determine the taxonomic classification of this group, revealing that it belonged to Gibbsiella quercinecans. The increasing reports of this bacterium from different woodland tree hosts suggest its opportunistic role as an individual causative agent, necessitating monitoring of its host expansion and morbidity.
Advertising doubt in early modern Italy: Doubt and ignorance in early modern paratexts
Authors: Faini Marco 
Published: August 2023

AbstractSpelled in several different ways, the word ‘doubt’, usually in the plural ‘doubts’ (dubbi, dubitazioni) appears on the frontispiece of several works printed in Venice and elsewhere in Italy in the sixteenth century. Building on different traditions, ranging from the pseudo‐Aristotelian Problemata to Medieval didactic literature, these texts, normally in the vernacular, address questions that the average reader may have on a variety of topics: from thermal baths to indulgences, from natural philosophy to duel. While usually the term ‘doubt’ means ‘question’, things can be sometimes less straightforward, especially when it comes to religious texts or works penned by unorthodox writers, as in the case of Ortensio Lando's Quattro libri di dubbi. This article will explore paratextual elements of works addressing doubts focusing on a variety of topics such as readership, definitions of doubt and its function, the role of these works in the dissemination of knowledge.
Impact of information and communication technologies on fertilizer and pesticide use efficiency of China's grain production

Published: August 2023

AbstractBased on a panel data from National Rural Fixed Point Survey (NRFP), this study explored the effects of information and communication technologies (ICTs) on the fertilizer and pesticide use efficiency of China's grain production and the mechanisms using stochastic frontier analysis (SFA) and two‐way fixed‐effects model with two‐stage least square (2SLS) estimation. The results show that the average fertilizer use efficiency (FE), pesticide use efficiency (PE) and comprehensive fertilizer and pesticide use efficiency (CFPE) of grain production were 0.286, 0.404, and 0.364 respectively during 2003–2011. It should be noted that the CFPE decreased by 48.39% during 2003–2011 and showed a descending trend in all regions. ICTs had significant positive effects on FE, PE, and CPFE which could be explained by providing farmers more sustainable knowledge and hence shifting farming practices from overusing fertilizer towards using farmyard manure as a substitute. ICTs' positive effects were more pronounced for farmers with higher‐level education and in central region. Additionally, ICTs had significant spillover effects, extending from users to nonusers within the villages. These results suggest that ICTs could be considered as an effective way to increase the fertilizer and pesticide use efficiency and promote the sustainable development of agriculture in China.
Reducing statistics anxiety and academic procrastination among Israeli students: A pilot program
Authors: Kadosh Mazi , Hen Meirav , Ferrari Joseph R. 
Published: August 2023

AbstractMany college students consider statistical courses as frightening and demanding, yielding high anxiety and low competence, and correlating with maladaptive academic behaviors and low achievement. With undergraduate students, the present pre‐post study compared a supportive online teaching program utilizing mandatory statistical exercises (n = 37) with a no intervention, optional exercise statistics class (n = 32). We evaluated whether our statistics teaching intervention decreased test anxiety and academic procrastination and increased academic self‐efficacy and academic achievements. Results indicated a decrease in academic procrastination and test anxiety at course end for intervention group and an increase in test anxiety for control group. At the end of the course intervention group reported higher academic self‐efficacy and achievements. Teaching statistics using mandatory supportive activities might contribute to more positive psychological outcomes (eg, higher academic self‐efficacy and lower academic procrastination) and higher academic achievements.

Published: August 2023

The herbal cleansing gel from turmeric extract is a natural skin care product with antioxidant, antimicrobial, and anti-inflammatory properties. Despite its advantages, turmeric extract has a higher metabolism, a low absorption rate, stability, and solubility. Encapsulation of turmeric extract had been developed to increase the bioavailability of turmeric extract for topical drug delivery. Hence, turmeric extract is encapsulated via nanostructured lipid carriers (NLCs) to produce turmeric extract-loaded nanostructured lipid carriers (T-NLCs). This project highlights the formulation and characterization of an herbal cleansing gel from encapsulated turmeric extract. To produce T-NLCs, medium-chain triglycerides (MCT) as liquid lipid and glycerol monostearate (GMS) as solid lipid generated an imperfect matrix incorporating turmeric extract. The T-NLCs were then characterized in terms of particle size, polydispersity index, zeta potential, encapsulation efficiency, and stability. The T-NLCs exhibited particle size 129.407 ± 1.278 nm, polydispersity index 15.067 ± 2.105%, zeta potential -44.7 ± 1.8 mV, encapsulation efficiency 98.04 ± 9.19 % and remained stable over 30 days. The herbal cleansing gel was formulated with T-NLCs and characterized in term sensory test. The formulation is believed to improve the turmeric extract's phytochemical stability, biocompatibility, skin permeability, and dermo-cosmetic efficiency. In conclusion, developing turmeric in an innovative encapsulated formulation has aided in developing herbal-based cosmetic products for a wide range of skin care systems.

AbstractWe study the moments ofL‐functions associated with primitive cusp forms, in the weight aspect. In particular, we obtain an asymptotic formula for the twisted moments of alongDirichlet polynomial with modular coefficients. This result, which is conditional on the Generalized Lindelöf Hypothesis, agrees with the prediction of the recipe by Conrey, Farmer, Keating, Rubinstein and Snaith.
Associahedra for finite‐type cluster algebras and minimal relations between g‐vectors
Authors: Padrol Arnau , Palu Yann , Pilaud Vincent , Plamondon Pierre‐Guy 
Published: August 2023

AbstractWe show that the mesh mutations are the minimal relations among the ‐vectors with respect to any initial seed in any finite‐type cluster algebra. We then use this algebraic result to derive geometric properties of the ‐vector fan: we show that the space of all its polytopal realizations is a simplicial cone, and we then observe that this property implies that all its realizations can be described as the intersection of a high‐dimensional positive orthant with well‐chosen affine spaces. This sheds a new light on and extends earlier results of Arkani‐Hamed, Bai, He, and Yan in type and of Bazier‐Matte, Chapelier‐Laget, Douville, Mousavand, Thomas, and Yıldırım for acyclic initial seeds. Moreover, we use a similar approach to study the space of polytopal realizations of the ‐vector fans of another generalization of the associahedron: nonkissing complexes (also known as support ‐tilting complexes) of gentle algebras. We show that the space of realizations of the nonkissing fan is simplicial when the gentle bound quiver is brick and 2‐acyclic, and we describe in this case its facet‐defining inequalities in terms of mesh mutations. Along the way, we prove algebraic results on 2‐Calabi–Yau triangulated categories, and on extriangulated categories that are of independent interest. In particular, we prove, in those two setups, an analogue of a result of Auslander on minimal relations for Grothendieck groups of module categories.
