AbstractNovel coordination polymers embedding electroactive moieties present a high interest in the development of porous conducting materials. While tetrathiafulvalene (TTF) based metal‐organic frameworks were reported to yield through‐space conducting frameworks, the use of S‐enriched scaffolds remains elusive in this field. Herein is reported the employment of bis(vinylenedithio)‐tetrathiafulvalene (BVDT‐TTF) functionalized with pyridine coordinating moieties in coordination polymers. Its combination with various transition metals yielded four isostructural networks, whose conductivity increased upon chemical oxidation with iodine. The oxidation was confirmed in a single‐crystal to single‐crystal X‐ray diffraction experiment for the Cd(II) coordination polymer. Raman spectroscopy measurements and DFT calculations confirmed the oxidation state of the bulk materials, and band structure calculations assessed the ground state as an electronically localized antiferromagnetic state, while the conduction occurs in a 2D manner. These results are shedding light to comprehend how to improve through‐space conductivity thanks to sulfur enriched ligands.
Probing a General Strategy to Break the C−C Bond of Benzene by a Cyclic (Alkyl)(Amino)Aluminyl Anion
Authors: Xu Fangzhou , Zhu Jun 
Published: November 2022

AbstractThe oxidative addition of C−C bonds in aromatic hydrocarbons by low valent main group species has attracted considerable attention from both theoretical and experimental chemists due to the big challenge in breaking their aromaticity. Herein, a general strategy to break the C−C bonds in benzene by cyclic (alkyl)(amino)aluminyl anion is demonstrated via density functional theory (DFT) calculations. The results suggest that the activation of the C−C bond of benzene by this anion is both kinetically and thermodynamically unfavorable whereas introducing electron‐withdrawing groups makes such C−C bond activation becomes favorable both kinetically and thermodynamically. Such a sharp change on the kinetics and thermodynamics could be rationalized by the frontier molecular orbital theory by decreasing the lowest unoccupied molecular orbitals of the mono‐ and disubstituted benzenes. Aromaticity is found to stabilize the transition state for the ring open step. All these findings can help develop the chemistry of small‐molecule activation.

SummarySpell checker is the application, which helps in finding the spelling errors in a given text. Applications like word processors, mails, search engines, speech recognition and social media forums need these kinds of spell checking tools to increase the correctness of the system. Spell checking is completely implemented in languages such as English, French, and Chinese. But as far as Indian regional languages is concerned, very few works have been carried out, that too partially. Tamil is one such Indian regional language, which requires a fully implemented spell checking application as many people started using this language in social media platforms like Facebook and Twitter. Spelling errors fall on different categories in Tamil language, which involves Sandhi errors, Homophone errors (Mayangoli), and misspelt words error. To tackle all these errors, a new ensemble approach is proposed in this paper. The proposed approach consists of Levenshtein's edit distance algorithm, rule‐based algorithm, Soundex algorithm along with LSTM (Long Short Term Memory) model. We have used a special feature called combine character splitting of Tamil alphabets for feeding the LSTM model to improve the performance of the system. Proposed system produced an accuracy of 95.67%, which is approved by the Tamil scholar.
Lewis Acidity Trend of Boron and Aluminium Trihalides: If Not π Back‐Bonding, What Else?**
Authors: Thayyil Ashith , Parambil Priyakumari Chakkingal 
Published: November 2022

AbstractLewis acidity trend of boron trihalides is a subject that has received a variety of explanations, and still, the simple π back‐bonding based one is believed by most, perhaps because of its simplicity, irrespective of opposing findings. Herein we try to give an alternative explanation based on qualitative Molecular Orbital (MO) theory and support that quantitatively by Generalized Kohn‐Sham Energy Decomposition Analysis. While the role of orbital overlap on the orbital interaction energy is widely known, the role of electronegativity of the atoms involved is often overlooked. Here we find that the Lewis acidity trend of boron and aluminium halides can be explained by the Wolfsberg‐Helmholz (W−H) formula for resonance integral. The MO theory‐based predictions are valid only when the orbital interactions are strong enough. In weakly interacting systems, the effect of orbital interactions can be overshadowed by other effects such as Pauli repulsion, dispersion, etc. Thus the Lewis acidity trend of boron and aluminium halides can vary depending on the strength of the interacting Lewis base. We believe that this work would enable one to gain a better understanding not only on the Lewis acidity of boron trihalides and its heavy analogs but also on a variety of related problems such as the stronger π acidity of CS compared to CO and weaker π bonding between heavy atoms.
Efficient Electrotransformation of Bacillus thuringiensis for Gene Manipulation and Expression
Authors: Zegeye Ephrem Debebe , Aspholm Marina 
Published: November 2022

AbstractGenetic manipulation of Bacillus spp., such as B. thuringiensis and B. cereus, is laborious and time consuming due to challenges in transformation of the plasmid DNA construct. Larger shuttle plasmids, such as pMAD, that are commonly used in markerless gene replacement are particularly difficult to transform into Bacillus spp. Here, we present robust protocols that work efficiently for the transformation of both small and large plasmid constructs into B. thuringiensis. Our protocols involve preparation of efficient electrocompetent Bacillus cells by cultivating the cells in the presence of a cell wall–weakening agent, followed by washing the cells with optimized solutions. The protocols further highlight the importance of using unmethylated plasmid DNA for the efficient transformation of B. thuringiensis. © 2022 The Authors.

AbstractThe importance of thermal refuges in a rapidly warming world is particularly evident for migratory species, where individuals encounter a wide range of conditions throughout their lives. In this study, we used a spatially explicit, individual‐based simulation model to evaluate the buffering potential of cold‐water thermal refuges for anadromous salmon and trout (Oncorhynchus spp.) migrating upstream through a warm river corridor that can expose individuals to physiologically stressful temperatures. We considered upstream migration in relation to migratory phenotypes that were defined in terms of migration timing, spawn timing, swim speed, and use of cold‐water thermal refuges. Individuals with different migratory phenotypes migrated upstream through riverine corridors with variable availability of cold‐water thermal refuges and mainstem temperatures. Use of cold‐water refuges (CWRs) decreased accumulated sublethal exposures to physiologically stressful temperatures when measured in degree‐days above 20, 21, and 22°C. The availability of CWRs was an order of magnitude more effective in lowering accumulated sublethal exposures under current and future mainstem temperatures for summer steelhead than fall Chinook Salmon. We considered two emergent model outcomes, survival and percent of available energy used, in relation to thermal heterogeneity and migratory phenotype. Mean percent energy loss attributed to future warmer mainstem temperatures was at least two times larger than the difference in energy used in simulations without CWRs for steelhead and salmon. We also found that loss of CWRs reduced the diversity of energy‐conserving migratory phenotypes when we examined the variability in entry timing and travel time outside of CWRs in relation to energy loss. Energy‐conserving phenotypic space contracted by 7%–23% when CWRs were unavailable under the current thermal regime. Our simulations suggest that, while CWRs do not entirely mitigate for stressful thermal exposures in mainstem rivers, these features are important for maintaining a diversity of migration phenotypes. Our study suggests that the maintenance of diverse portfolios of migratory phenotypes and cool‐ and cold‐water refuges might be added to the suite of policies and management actions presently being deployed to improve the likelihood of Pacific salmonid persistence into a future characterized by climate change.

AbstractMono benzoxazine appended N‐capped amino bis(disubstitutedphenol) ligands [II(a–c)] upon reaction with VVO(OEt)3 in a 1 : 1 molar ratio in EtOH/MeOH give [{VVO}en(3,5‐dtbb)3] (1), [{VVO}en(3‐tb,5‐mb)3] (2) and [{VVO}en(3,5‐dmb)3] (3). During the reaction, the benzoxazine ring opens with the loss of methylene group and the newly formed ligands, N,N‐bis(2‐hydroxy‐3,5‐disubstitutedbenzyl)‐N’‐2‐hydroxy‐3,5‐disubstituted benzyledene‐1,2‐diaminoethane [III(a–c)], behave as tribasic pentadentate in these complexes. Under similar conditions, when [MVIO2(acac)2] (M=Mo or W; Hacac=acetylacetone) reacts with II(a–c), these ligands retain their identity and form cis‐[MVIO2] complexes, [{MoVIO2}{en(3,5‐dtbb)2(6,8‐dtbbenzox)}] (4), [{MoVIO2}{en(3‐tb,5‐mb)2(6‐tb,8‐mbbenzox)}] (5) and [{MoVIO2}{en(3,5‐dmb)2(6,8‐dmbenzox)}] (6), [{WVIO2}{en(3,5‐dtbb)2(6,8‐dtbbenzox)}] (7), and [{WVIO2}{en(3‐tb,5‐mb)2(6‐tb,8‐mbbenzox)}] (8). However, the benzoxazine ring ruptures in case of ligand IIc under these conditions and form [{WVIO2}{en(3,5‐dmb)3}] (10), similar to complexes 1–3. Complex [{WVIO2}{en(3,5‐dmb)2(6,8‐dmbenzox)}] (9), having structure similar to 4–8, could only be obtained when the reaction was carried out in toluene. Not only 9, even complexes 4–8 can be isolated in toluene. Rupturing of both benzoxazine rings has also been experienced when ligands 1,2‐bis(6,8‐disubstitutedbenzo[e][1,3]oxazin‐3(4H)‐yl)ethane [I(a–c)] react with [MVIO2(acac)2] (M=Mo or W) in MeOH and give salan type complexes [(MVIO2)en(3,5‐dtbb)2] [M=Mo (11), M=W (14)], [(MVIO2)en(3‐tb,5‐mb)4] [M=Mo (12), M=W (15)] and [(MVIO2)en(3,5‐dmb)4] [M=Mo (13), M=W (16)]. Complexes 1–9 have been used as catalyst for the multicomponent Biginelli reaction for the synthesis of 3,4‐dihydropyrimidin‐2(1H)‐ones (DHPMs) and oxidative bromination of phenol derivatives.

Published: November 2022

AbstractNowadays, increase in a health‐conscious population, interest in the nutritional properties and bioactive components of foods has also increased. Vegetable oils can be consumed in both virgin and refined forms, but there is a growing interest in the consumption of virgin oils as functional foods. Refining includes the elimination of unwanted components while maintaining essential elements. However, due to severe conditions such as high temperatures and harsh chemicals of the refining process, removal of desirable components and formation of unwanted components are sometimes unavoidable, which can cause serious health issues. The aim of this work is to provide an overview of nutritional and health aspects of refined and unrefined vegetable oils. Their role in causing several diseases and health issues, such as cardiovascular diseases, obesity, liver disorders, renal disorders, inflammation, diabetes, cancer, osteoporosis, neurodegenerative disorders, allergies, and edema are investigated. Moreover, it is known that virgin oils have beneficial effects on gut microbiota which affect the nervous system and body health, as well as regulating inflammatory and metabolic changes; thus, including virgin oils in the diet is highly suggested. This review is a comprehensive collection of reports on the impact of refining on the nutritional and health effects of vegetable oils.

Published: November 2022

AbstractDecades of research have shown that social dominance orientation (SDO) is one of the most important predictors of anti‐immigrant attitudes. However, the mechanisms through which SDO can explain prejudice have been studied insufficiently. Using rich and diverse samples from France and from the province of Québec in Canada, the present research provides a cross‐national (N= 1,852) and prospective (N= 534) analysis of a theoretical model in which the dimensions of SDO are indirectly predicting anti‐immigrant prejudice via the intergroup ideologies of assimilation, multiculturalism, colour blindness and interculturalism. Results showed that interculturalism, a hierarchy‐attenuating ideology was found to be a robust mechanism to explain the subtle effects of SDO‐E on anti‐immigrant prejudice whereas assimilation, a hierarchy‐enhancing ideology was playing a more important role to explain direct and blatant effects of SDO‐D on prejudice. The two most studied diversity approaches, multiculturalism and colour blindness, were largely redundant once interculturalism was considered. This pattern occurred in both France and Québec hence, favouring the context‐independent pathway.

Published: November 2022

AbstractIndustrial Internet of Things (IIoT) is a very effective and efficient way to track products during their production, packaging, storage, and shipments. It can also help in monitoring their real‐time conditions such as location, speed of moments, and temperature. Presently most of the supply chain management systems are not effective due to their inefficient tracking of real‐time shipments, long delays in shipments and lost identification on a real‐time basis, and uneconomical storage of goods. To solve these problems, an IoT‐based secure and sustainable smart supply chain system using sensor networks is proposed that provides real‐time shipment tracking, storage, delay, and lost identification. Threshold‐based weighted probability formula is devised by considering the average distance and node spacing of sensor nodes, total network energy, residual, and maximum energy parameters to alleviate the hot spot problem. Additionally, the communication signals are transmitted in compression form with end‐to‐end encryption that reduces the use of bandwidth by decreasing the signal size. The percentage increment in the stability and the network lifespan of the proposed method is 35.19% and 7.23% & 119.33% and 71.72% as compared to the T. Senthil et al method and S. Singh's method, respectively.
Bioactive gliadin electrospinning loaded with Zataria multiflora Boiss essential oil: Improves antimicrobial activity and release modeling behavior

Published: November 2022

AbstractThis study aimed to produce electrospun gliadin nanofibers containing Zataria multiflora Boiss essential oil (ZMEO) (5, 10, and 15% w/w), thereby developing active, sustained‐release antimicrobial mats. By increasing the level of the ZMEO, the zeta potential and electrical conductivity increased, but the viscosity and consistency index decreased. All feed solutions demonstrated shear‐thinning behavior, and the power law model was the best model. Field emission scanning electron microscopy (FESEM) images proved that the gliadin nanofibers showed a uniform, beaded‐free structure at different levels of ZMEO, with an average diameter of between 403.87 ± 15.29 and 522.19 ± 11.23 nm. Increments in the level of ZMEO decreased the mats' tensile strength and Young's modulus but increased their elongation at break. Fourier transform infrared (FTIR) and differential scanning calorimetry (DSC) analysis confirmed that the ZMEO was well loaded within these structures, augmenting its thermal stability. The studied Gram‐negative bacteria (Escherichia coli and Pseudomonas aeruginosa) were more resistant to the ZMEO than the Gram‐positive bacteria (Bacillus cereus and Staphylococcus aureus). The Peleg model was the most suitable model for describing the ZMEO release behavior, the mechanism of which was primarily Fickian diffusion.

Published: November 2022

AbstractA high‐rate oxygen reduction reaction (ORR) is necessary for polymer electrolyte membrane fuel cells (PEMFC). In this work, by using a solution plasma technique, Pt catalytic particles coated with N‐doped graphene (Pt‐NG) were effectively produced at 25°C. According to transmission electron microscope images, the average diameter of Pt particles was 4 nm, while the graphene layer thickness was less than 1 nm. A catalytic layer of Pt‐NG supported on single‐walled carbon nanotubes (Pt‐NG/SWCNT) was synthesized. Cyclic voltammetry was used to assess the ORR characteristics of Pt‐NG/SWCNT catalytic layers. Only at a density of SWCNT to solvent ratio of 0.75 mg ml−1 were the ORR peaks clearly visible. Because of the high resistivity of SWCNT layers, the ORR peaks in other ranges, 0.4 mg ml−1 to 2.0 mg ml−1, were not clearly observed. The effect of SWCNT concentration on conductivity was proven to follow the basic concept of the percolation threshold.

AbstractHuman–robot interface (HRI) electronics are critical for realizing robotic intelligence. Here, we report graphene‐based dual‐function acoustic transducers for machine learning‐assisted human–robot interfaces (GHRI). The GHRI functions both an artificial ear through the triboelectric acoustic sensing mechanism and an artificial mouth through the thermoacoustic sound emission mechanism. The success of the integrated device is also attributed to the multifunctional laser‐induced graphene, as either triboelectric materials, electrodes, or thermoacoustic sources. By systematically optimizing the structure parameters, the GHRI achieves high sensitivity (4500 mV Pa–1) and operating durability (1 000 000 cycles and 60 days), capable of recognizing speech identities, emotions, content, and other information in the human speech. With the assistance of machine learning, 30 speech categories are trained by a convolutional neural network, and the accuracy reaches 99.66% and 96.63% in training datasets and test datasets. Furthermore, GHRI is used for artificial intelligence communication based on recognized speech features. Our work shows broad prospects for the development of robotic intelligence.image

SummaryHow forward guidance influences expectations is not fully understood. To study this, I construct central bank data that includes forward guidance and its attributes, central bank projections, and quantitative easing, which I combine with survey data. I describe how, when, and where forward guidance has worked. I estimate that forecasters revised their interest rate forecasts in the intended direction by five basis points on average following a forward guidance change. I provide estimates for The Federal Reserve, European Central Bank, Bank of England, Bank of Canada, Reserve Bank of Australia, Reserve Bank of New Zealand, Sveriges Riksbank, and Norges Bank.
Acute High Dietary Phosphorus Following Low‐Phosphorus Diet Acclimation Does Not Enhance Intestinal Fractional Phosphorus Absorption in Nephrectomized Male Rats

ABSTRACTDietary phosphorus restriction and phosphorus binders are commonly prescribed for patients with chronic kidney disease (CKD). However, occurrences of non‐adherence to these interventions are common. As low‐phosphorus (LP) diets have been consistently experimentally shown in vitro to increase intestinal phosphorus absorption efficiency, a bout of non‐adherence to diet or binders may cause an unintended consequence of enhanced intestinal phosphorus absorption. Thus, we aimed to determine the effect of a single bout of high‐phosphorus (HP) intake after acclimation to a LP diet. Male Sprague Dawley rats with 5/6 nephrectomy (n = 36) or sham operation (n = 36) were block‐randomized to 1 of 3 diets: LP (0.1% P w/w), HP (1.2%), or LP followed by acute HP (LPHP 0.1% then 1.2%). Phosphorus absorption tests were conducted using 33P radioisotope administrated by oral gavage or intravenously (iv). Although the overall two‐way ANCOVA model for intestinal fractional phosphorus absorption was non‐significant, exploratory comparisons showed intestinal fractional phosphorus absorption efficiency tended to be higher in rats in the LP compared with HP or LPHP groups. Rats in the HP or LPHP groups had higher plasma phosphorus compared with rats in the LP group, but the LPHP group was not different from the HP group. Gene expression of the major intestinal phosphate transporter, NaPi‐2b, was lower in the jejunum of rats in the LPHP group compared with rats in the HP group but not different in the duodenum. These results demonstrate that an acute HP load after acclimation to a LP diet does not lead to enhanced intestinal fractional phosphorus absorption efficiency in 5/6 nephrectomized male rats. These data provide evidence against the notion that dietary phosphorus restriction or binder use adversely increases absorption efficiency after a single instance of dietary or binder non‐adherence. However, other adverse consequences of fluctuating dietary phosphorus intake cannot be ruled out. © 2022 The Authors.
