FBO‐RNN: Fuzzy butterfly optimization‐basedRNN‐LSTMfor extracting sentiments from Twitter Emoji database
Authors: Venkataraman Jayalakshmi , Mohandoss Lakshmi 
Published: March 2023

SummarySocial media networks have seen a significant increase in purpose and scale. Sentimental analysis is a component of social networking platforms that uses shared material to infer information about individual sentiments and emotions. In recent years, sentiment analysis (SA) research has grown in popularity. Twitter is the most popular social media platform, with users from many languages and cultures participating. Emojis are used by users to express themselves, and social media platforms contain a wide range of symbols, emotions, and opinions. A novel framework for SA based on Emojis is presented in this article. Initially, the noise‐free videos and images are filtered. The dictionary of Jieba was obtained by adding the English Emoji lexicon and English Internet slang lexicon to segment English text. Initially, the Emojis are converted into textual features. Different sentiment classes such as positive, very positive, neutral, negative, and very negative classes are classified using long short‐term memory (LSTM) in the recurrent neural network (RNN)‐based Fuzzy Butterfly Optimization (FBO) algorithm. The freeware WEKA software tool with different evaluation measures performs experimental investigations. Ultimately, the proposed model demonstrates superior results in the case of SA than other state‐of‐the‐art methods.

Published: March 2023

AbstractUnstable interface between highly reductive Li metal and a conventional liquid electrolyte leads to uncontrollable Li dendrites and Li pulverization, thus limiting the practical applications of Li metal batteries with high energy density. Herein, a fluorinated quasi‐solid polymer electrolyte is synthesized to stabilize Li metal via the C−F/LiF enriched solid electrolyte interphase (SEI) derived from the fluorinated polymer skeleton. Benefiting from the homogenized ion plating/stripping process guided by lithophilic C−F and rapid Li+ transportation assisted by LiF, Li dendrites and Li pulverization are suppressed. As a result, the Li||Li symmetrical cell with the fluorinated quasi‐solid polymer electrolyte remains stable over 1400 h at a current density of 0.3 mA cm−2. LiNi0.8Co0.1Mn0.1O2||Li battery delivers a long‐term cycling performance, where the capacity retains 87.77 % of its initial state after 300 cycles at 0.5 C in the voltage range from 2.8 to 4.4 V.

Published: March 2023

SummaryThis work proposes a real‐time and online energy scheduling optimization algorithm for nanosatellites operating with a direct energy transfer (DET) architecture. The goal of the algorithm is to optimize energy utilization by maximizing energy harvesting, meeting task deadlines and priorities, and ensuring a minimum quality of service (QoS) for the system. The algorithm is composed of a modified perturb and observe algorithm to reach the best energy efficiency point of the solar panels, a task prioritization algorithm to guarantee their times and minimum QoS, and a backpack optimization problem to maximize the energy efficiency of the satellite. To demonstrate the effectiveness of the proposed algorithm, simulations of a nanosatellite operating in a given orbit, attitude, and thermal parameters were conducted and compared to other task scheduling strategies. The results showed that the proposed energy scheduling algorithm had the best performance in terms of energy balance and average power consumption, with an energy balance up to 16% higher compared to the other tested strategies. This demonstrates the ability of the proposed algorithm to optimize power consumption and energy utilization, as well as efficiently schedule tasks to maximize energy harvesting. The proposed energy scheduling optimization algorithm has the potential to be a useful tool for the design and optimization of future satellite missions and could potentially guide the design of electrical power systems for new CubeSat missions operating with a DET architecture. The algorithm's ability to optimize energy utilization and ensure a minimum QoS for the system could improve the overall efficiency and performance of the satellite.

AbstractObjectivesAnastomotic biliary strictures (ABSs) are common complications following living donor liver transplantation (LDLT). We evaluated the feasibility of a novel removable, intraductal, fully covered, self‐expandable metallic stent (FCSEMS) for the treatment of ABSs following LDLT.MethodsNine patients with duct‐to‐duct ABSs that developed following LDLT were prospectively enrolled in this study. We placed a short FCSEMS with a long lasso and middle waist formation in each patient's ABS above the papilla and removed it 16 weeks later.ResultsThe FCSEMS placements were successful in all nine cases. Four patients experienced mild cholangitis, which was resolved with conservative treatment. Additionally, there was one case of distal migration. The FCSEMSs were successfully removed from all the patients, and the clinical success rate was 100%. Stricture recurrence occurred in one (11.1%) patient during the follow‐up period.LimitationsThe small number and lack of comparison with other types of FCSEMSs and plastic stents.ConclusionsIntraductal placement of FCSEMSs is useful for treating refractory ABSs after LDLT, although further studies are required with larger sample sizes.
Layered double hydroxide‐derived copper‐based oxygen carriers for chemical looping applications: Oxygen release kinetics and impact of loading on long‐term performance
Authors: High Michael , Song Qilei , Campbell Kyra L. Sedransk , Fennell Paul S. 
Published: March 2023

AbstractChemical looping with oxygen uncoupling, a variant of chemical looping combustion, requires chemically and physically stable oxygen carriers over long‐term redox cycling. Copper‐based oxygen carriers are characterised by high oxygen release rates but experience sintering at high temperatures. The use of layered double hydroxides (LDHs), prepared via co‐precipitation, as oxygen carrier precursors has been shown to effectively limit deactivation of copper‐based mixed metal oxides (MMOs) over extended redox cycling. The LDH‐derived MMOs have highly dispersed metal oxide within a stable support; the high dispersion of metals is due to the LDH precursor structure. In this work, a fluidised bed reactor (FBR) was used to study the intrinsic kinetics of oxygen release from CuO/MgAl2O4 oxygen carriers synthesised via the LDH‐MMO design strategy. The long‐term performance of MMOs with higher loadings of CuO, calcined from LDHs with higher Cu contents, was also investigated using an FBR. The intrinsic kinetics were determined using a kinetic model incorporating an effectiveness factor. By minimising the effects of intra‐ and inter‐particle mass transfer, the activation energy and the pre‐exponential factor of the lower loading MMOs were determined to be 51 ± 3 kJ mol−1 and 0.0567 s−1, respectively. All MMOs showed excellent stability over 100 redox cycles in a thermogravimetric analyser. However, the pH during co‐precipitation of the LDHs affected the stability of the MMOs in an FBR. The MMOs calcined from LDHs synthesised at pH 9.5 disintegrated during operation, whilst those produced from LDHs synthesised at pH 11 maintained high conversion and physical integrity over 100 redox cycles. © 2023 The Authors.

Ozone oxidation of cysteine in optically trapped aqueous micro‐droplets
Authors: Li Jia‐Rong , Chang Yuan‐Pin 
Published: March 2023

AbstractThe ozone (O3) oxidation kinetics of cysteine in aqueous micro‐droplets at different acidities is investigated in this study via aerosol optical tweezers coupled with Raman spectroscopy. This study exploits the O3 oxidation of cysteine near the interface of micro‐droplets as a model system to elucidate the oxidation damage of amino acids in biosurfaces. For each optically trapped micro‐droplet, Raman spectroscopy is used to determine its droplet radius, concentrations of solutes, and droplet pH, as well as their time evolutions during the kinetics measurements. The bimolecular rate coefficients of the cysteine + O3 reaction measured in micro‐droplets are around 4 × 105 M−1 s−1 and 2 × 104 M−1 s−1 for pH ≈ 5 and 0.5, respectively. These results agree with the previous bulk measurements, indicating that the observed aerosol kinetics can be solely rationalized via diffusion‐limited kinetics. The results also indicate that a high‐ionic strength could enhance the cysteine + O3 reaction, particularly for the zwitterion form of cysteine. The results imply that when surfactant proteins in lung fluids are exposed to ambient O3, the cysteine residues in proteins will be attacked by O3 at first due to the high reactivity of the thiol moiety in cysteine.

Published: March 2023

AbstractObjectivesThe utilization of online teaching and learning in dental education has grown during the past two academic years. In addition to its numerous advantages, the modality also has its limitations. The objective of this qualitative study was to explore the perceptions of oral health sciences students at the University of British Columbia (UBC) and the University of Toronto (UofT) regarding their experiences with online learning over the course of 2 pandemic‐impacted years.MethodsInterpretive Description was used as a methodology to guide semi‐structured data collection. Individual interviews and focus groups were conducted with graduate and undergraduate dental and dental hygiene students at UBC and UofT. Qualitative data were coded and analyzed using a thematic approach.ResultsA total of 31 interviews and 4 focus groups were conducted. Online teaching and learning demonstrated many advantages, including flexibility, sustainability of curricular content, and promoting inclusivity in the classroom. Students indicated that due to online learning, there were opportunities to gain resources in practicing self‐care and additional time to connect with family. Reported limitations of online classrooms included the loss of attentiveness, challenging content, and logistical challenges. Isolation and physical symptoms experienced in online classrooms with prolonged screen times were described as potential threats.ConclusionsThe results of this study call for developing a structured and sustainable blended approach that balances the limitations of online classrooms with the interaction and engagement of in‐person classrooms and patient care experiences. Based on the students’ perspectives toward online learning, a road map was provided to dental educators to consider when designing future dentistry curricula.
Interpretation(s) of essential value in operant demand
Authors: Gilroy Shawn P. 
Published: March 2023

AbstractThe operant demand framework has achieved high levels of adoption as an approach to quantify how various ecological factors influence choice. A central goal of the framework proposed by Hursh and Silberburg (2008) was to isolate the “essential value” of reinforcers—namely, their effects on behavior given various contextual factors. The effect of reinforcers on behavior is a phenomenon that is expected to vary as a function of reinforcer magnitude/dosage (i.e., units of reinforcement), price (i.e., schedule requirements), the intensity of demand (i.e., consumption in free operant conditions), the availability of reinforcers (i.e., supply, presence of alternatives), and the individual's current and historical context. This technical report provides a historical summary of the concept, describes the quantitative basis for essential value in the framework of Hursh and Silberburg (2008), reviews prior attempts to extract a generalizable index of essential value, and presents a newer formulation using exact solution that provides a more succinct and durable index. Proofs and solutions are provided to clarify the bases for novel and existing representations of essential value. Recommendations are provided to improve the precision and accuracy of behavioral economic metrics as well as support consensus regarding their interpretation in the operant demand framework.

AbstractBackgroundRetaining women and racially minoritized individuals in engineering programs has been a subject of widespread discussion and investigation. While the sense of belonging and its link to retention have been studied based on student characteristics, there is an absence of studies investigating the importance of students' social identities to their sense of belonging in engineering.Purpose/HypothesisThis study examines differences in race/ethnic identity centrality, gender identity centrality, and sense of belonging in engineering by subgroups of undergraduate engineering students at Hispanic‐Serving Institutions (HSIs). Subsequently, it examines the extent to which these identity centralities predict a sense of belonging in engineering for each subgroup.Design/MethodSurvey data was collected from 903 Latinx and 452 White undergraduate engineering students from seven HSIs across the continental United States. Multivariate analysis of variance and sequential multivariate linear regression were used to evaluate the research questions.ResultsLatinx students had higher identity centralities but a similar sense of belonging in the engineering community as White students. Latinos and Latinas had an equivalent sense of belonging in engineering, whereas White women were higher than White men. In the full models, race/ethnic identity centrality significantly, and positively predicted a sense of belonging in engineering for Latinos and White women. Gender identity centrality was not a significant predictor of a sense of belonging in engineering for either Latinx or White students.ConclusionsRace/ethnic and gender identity centrality are differentially important to the sense of belonging in engineering for students at Hispanic‐Serving Institutions based on their group membership at the intersection of race and gender.

AbstractCell and sub‐cellular anatomical adjustments are adaptations utilized by plants to tolerate abiotic stress. Both melatonin and Morinda lucida‐silver nanoparticles (ML‐AgNPs) are recognized as bio‐stimulants. The study examined the morphological changes and adaptive characteristics of these bio‐stimulants under water‐stress Eugenia uniflora. Twenty‐four hours was spent priming the seeds with melatonin (0.06 mg/L), ML‐AgNPs (0.06 mg/L), and a mixture (1:1) of the two. The seeds were sown and subjected to water stress for 7 days. The leaves, stems, and roots of water‐stressed E. uniflora were sectioned, dried, and examined using a microscope. Drought stress led to the production of non‐glandular trichomes on the abaxial and the transformation of paracytic stomata into diacytic stomata. During water stress, melatonin enlarges intercellular gaps and stomata, increases sponge and palisade parenchyma, and thickens epidermis (stem and root) and fibers. The ML‐AgNPs diminished the size of mesophyll, intercellular gaps, stomata, and stem fiber. The ML‐AgNPs increased the size of bulliform cells and activated the mechanical resistance features of sclerophyllous leaves (thick‐celled epidermis and sclerieds) and ray parenchyma (root and stem). Equally, Melatonin and ML‐AgNPs increased stem and root anatomical characteristics (xylem, bark, pith, cortex, epidermis, and vascular bundles). Stomata of E. uniflora are susceptible to alterations and undergo cell division into two new stomata (stomatogensis) in response to varying conditions (melatonin and ML‐AgNPs). Melatonin adopted a strategy for maintaining a high plant water status, possibly by osmoregulation, whereas E. uniflora primed with ML‐AgNPs survived by minimizing transpirational water loss through morphological changes.

Published: March 2023

AbstractExtracellular vesicles (EVs) are ideal for liquid biopsy, but distinguishing cancer cell‐derived EVs and subpopulations of biomarker‐containing EVs in body fluids has been challenging. Here, we identified that the glycoproteins CD147 and CD98 define subpopulations of EVs that are distinct from classical tetraspanin+ EVs in their biogenesis. Notably, we identified that CD147+ EVs have substantially higher microRNA (miRNA) content than tetraspanin+ EVs and are selectively enriched in miRNA through the interaction of CD147 with heterogeneous nuclear ribonucleoprotein A2/B1. Studies using mouse xenograft models showed that CD147+ EVs predominantly derive from cancer cells, whereas the majority of tetraspanin+ EVs are not of cancer cell origin. Circulating CD147+ EVs, but not tetraspanin+ EVs, were significantly increased in prevalence in patients with ovarian and renal cancers as compared to healthy individuals and patients with benign conditions. Furthermore, we found that isolating miRNAs from body fluids by CD147 immunocapture increases the sensitivity of detecting cancer cell‐specific miRNAs, and that circulating miRNAs isolated by CD147 immunocapture more closely reflect the tumor miRNA signature than circulating miRNAs isolated by conventional methods. Collectively, our findings reveal that CD147 defines miRNA‐enriched, cancer cell‐derived EVs, and that CD147 immunocapture could be an effective approach to isolate cancer‐derived miRNAs for liquid biopsy.

Published: March 2023

AbstractThe performance of the climate simulations by the regional climate model COSMO‐CLM forced by MPI‐ESM‐LR, as well as projected future temperature and precipitation conditions over northwestern Türkiye at the convection‐permitting resolution, are shown in this study. In terms of mean, maximum and minimum temperatures and daily total precipitation, the model response was examined. Comparisons with observations were made on an annual and seasonal basis. The convection‐permitting model (0.0275°) provides a satisfactory representation of annual and seasonal mean temperatures according to bias, MAE and RMSE. Better results were found for precipitation with respect to RE, MAE and RMSE. Finally, we used the RCP8.5 emission scenario to investigate future climate changes in terms of average temperature and precipitation variations for northwestern Türkiye, including Istanbul, over two projection periods (2041–2060 and 2071–2090) compared to the reference period (1991–2005). The model predicts significant warming in northwestern Türkiye, particularly in Istanbul and its environs, by the end of the century, as well as a general decrease in precipitation, especially evident in the spring and summer. The findings of this study can be used to develop climate adaptation policies based on temperature and precipitation variables in and around the study area.

Published: March 2023

AbstractBACKGROUNDGinkgo biloba leaves contain beneficial flavonoids, bilobalide (BB), and ginkgolides. However, the toxic ginkgolic acid (GA) limit its application. In this study, various traditional processing methods were used to prepare G. biloba leaf tea (GBLT), including white tea, black tea, dark tea, green tea, and freeze‐dried as control, followed by investigations of their effects on quality, antioxidant capacity, bioactive components, and cytotoxicity of the tea products.RESULTSResults showed that different processing methods significantly impact the tea products' quality indexes and the principal component analysis (PCA) and hierarchical cluster analysis (HCA) corroborated it. White tea had the highest total sugar (TS) and GA content and the most potent cytotoxicity on HepG2 cells. However, TS and GA content and the cytotoxicity of GBLT markedly decreased during fermentation and fixation. Moreover, white tea possessed higher total phenolic content (TPC), total flavonoid content (TFC), and more vigorous antioxidant activities than green tea, black tea, and dark tea. Terpene trilactones value was stable, but different catechins contents fluctuated according to the manufacturing process of different GBLTs. Among the four GBLTs, dark tea combining fixation and fermentation had the lowest GA content and cytotoxicity, less bioactive components reduction, appropriate quality, and stronger flavor.CONCLUSIONThese findings demonstrate that fixation and fermentation help reduce GAs during the manufacturing of GBLT. However, their ability to retain bioactive substances needs further optimization in future studies. © 2023 Society of Chemical Industry.
Universal continuous calculus for Su*‐algebras
Authors: Schötz Matthias 
Published: March 2023

AbstractUniversal continuous calculi are defined and it is shown that for every finite tuple of pairwise commuting Hermitian elements of a Su*‐algebra (an ordered *‐algebra that is symmetric, i.e., “strictly” positive elements are invertible and uniformly complete), such a universal continuous calculus exists. This generalizes the continuous calculus for ‐algebras to a class of generally unbounded ordered *‐algebras. On the way, some results about *‐algebras of continuous functions on locally compact spaces are obtained. The approach used throughout is rather elementary and especially avoids any representation theory.
