The Rohde‐like cells at the posterior end of the dorsal nerve cord of amphioxus (Cephalochordata)
Authors: Holland Nicholas D. , Holland Linda Z. 
Published: June 2024

AbstractFor postmetamorphic specimens of amphioxus (Cephalochordata), serial block‐face scanning electron microscopy (SBSEM) is used to describe the long‐ignored Rohde‐like cells (RLCs) at the extreme posterior end of the dorsal nerve cord. These cells, numbering about three dozen in all, are divisible into a group with larger diameters running near the dorsal side of the cord and a more ventral group with smaller diameters closely associated with the central canal of the neurocoel. It is possible that the smaller ventral cells might be generated at the ependymal zone of the dorsal nerve cord and later migrate to a dorsal position, although a functional reason for this remains a mystery. All the RLCs have conspicuous regions of microvilli covering as much as 40% of their surface; limited data (by others) on the more anterior bona fide Rohde cells also indicate an extensive microvillar surface. Thus, both the RLCs and the better‐known Rohde cells appear to be rhabdomeric photoreceptors, although a specific function for this feature is currently unknown. Even more perplexingly, although the Rohde cells are quintessential neurons extending giant processes, each RLC comprises a perikaryon that does not bear any neurites.

AbstractThe extensive consumption of chicken has resulted in the emergence of a significant environmental issue in the form of chicken feather waste. As such, there is an urgent need for the development of green treatment and recycling methods for chicken feathers. Chicken feathers can serve as a type of heteroatomic doping carbon source, making them an excellent candidate for the electrode materials used in electrochemical energy devices. Furthermore, their unique structures and functional groups make them highly promising for use as adsorbents, electronics, and building materials. In this paper, we provide a summary and review of recent progress made in the use of chicken feathers for energy and environmental applications. Based on the theoretical knowledge and practical applications presented in this review, promising green recycling processes of chicken feathers can be developed. These processes can help to reduce environmental pollution and promote sustainable development.
Improving ROUGE‐1 by 6%: A novel multilingual transformer for abstractive news summarization
Authors: Kumar Sandeep , Solanki Arun 
Published: June 2024

SummaryNatural language processing (NLP) has undergone a significant transformation, evolving from manually crafted rules to powerful deep learning techniques such as transformers. These advancements have revolutionized various domains including summarization, question answering, and more. Statistical models like hidden Markov models (HMMs) and supervised learning have played crucial roles in laying the foundation for this progress. Recent breakthroughs in transfer learning and the emergence of large‐scale models like BERT and GPT have further pushed the boundaries of NLP research. However, news summarization remains a challenging task in NLP, often resulting in factual inaccuracies or the loss of the article's essence. In this study, we propose a novel approach to news summarization utilizing a fine‐tuned Transformer architecture pre‐trained on Google's mt‐small tokenizer. Our model demonstrates significant performance improvements over previous methods on the Inshorts English News dataset, achieving a 6% enhancement in the ROUGE‐1 score and reducing training loss by 50%. This breakthrough facilitates the generation of reliable and concise news summaries, thereby enhancing information accessibility and user experience. Additionally, we conduct a comprehensive evaluation of our model's performance using popular metrics such as ROUGE scores, with our proposed model achieving ROUGE‐1: 54.6130, ROUGE‐2: 31.1543, ROUGE‐L: 50.7709, and ROUGE‐LSum: 50.7907. Furthermore, we observe a substantial reduction in training and validation losses, underscoring the effectiveness of our proposed approach.

AbstractThis study attempted to inspect the influence of green transformational leadership (GTL) on the development of business performance (FP) and environmental performance (EP) in SMEs of Vietnam with a mediating of green innovation (GI). Besides, the current study evaluated the positive impact of GTL on green human resource management (GHRM) and green thinking (GT), and ultimately on GI. The study investigated the hypotheses supplied by 416 survey samples from managers and directors at SMEs using structural equation modeling. Our findings reveal that GTL significantly influences the three green criterias, GHRM, GT, and GI. It investigates the impact of green factors in the context of Vietnamese SMEs. Specifically, the uniqueness of this study lies in examining the mediating role of GI with respect to the link between GTL and EP, FP, to compare how the indirect effects of GTL on EP and FP differ under the same conditions. Besides, the finding highlights that businesses will benefit from continual GI regarding the environment, earnings, and corporate image. Thus, the implications arising from this study and related documents contribute to helping managers understand the needs and benefits of green factors, thereby prioritizing the transmission of green goals to employees via vision and mission, thereby creating a new cultural dimension that contributes to the natural environment's sustainability. Furthermore, managers are urged to recruit, inspire, and provide opportunities for green human resources to use their potential for enhancing green products and processes to build the business and contribute to the environment.

Published: June 2024

AbstractBackgroundThe World Health Organization (WHO) reporting system for pancreaticobiliary cytopathology was released to internationalize the reporting, assisting in correct diagnosis and patient treatment with significant revisions from the previous Papanicolaou Society of Cytopathology (PSC) system. The “neoplastic: benign” and “neoplastic: other” categories have mostly been superseded by two new ones: “pancreatic neoplasia‐low‐grade” (PaN‐low) and “pancreatic neoplasia‐high‐grade” (PaN‐high), which classify intermediate neoplastic lesions based on cytological atypia. We aim to assess the reproducibility and risk of malignancy (ROM) for reporting pancreaticobiliary cytopathology by the WHO system in comparison with the PSC system.Materials and MethodsA retrospective study by reviewing archival slides sent for pancreaticobiliary cytological evaluation from June 2021 to June 2023, by two pathologists blinded to each other's findings. Absolute ROM was determined by histopathology/cell block study/clinical follow‐up (minimum 6 months)/overtly malignant imaging/metastasis.ResultsA total of 332 cases from 329 patients met the inclusion criteria, comprising pancreatic, gallbladder, and biliary lesions. The median patient age was 54 years (range, 14–86 years). The overall sensitivity of the test is 74.9% specificity is 93.2%, positive predictive value of 96.8%, negative predictive value of 57.6%, and a diagnostic accuracy of 81.8%.The absolute ROM for each site in all categories was comparable with that of the published data from the WHO system.ConclusionOur study highlights the reliability of the WHO system for guiding clinical decision‐making and patient management in the context of pancreaticobiliary. However, continual efforts among pathologists are essential to maintain consistent accuracy in cytological interpretations.
Trends in research approaches and gender in plant ecology dissertations over four decades
Authors: Poddar Urmi , Lam Kristi , Gurevitch Jessica 
Published: June 2024

AbstractDissertations are a foundational scientific product; they are the formative product that early‐career scientists create and share original knowledge. The methodological approaches used in dissertations vary with the research field. In plant ecology, these approaches include observations, experiments (field or controlled environment), literature reviews, theoretical approaches, or analyses of existing data (including “big data”). Recently, concerns have been raised about the rise of “big data” studies and the loss of observational and field‐based studies in ecology, but such trends have not been formally quantified. Therefore, we examined how the emphasis on each of these categories has changed over time and whether male and female authors differ in the methods employed. We found remarkable temporal consistency, with observational studies being dominant over the entire time span examined. There was an increase in the number of approaches employed per dissertation, with increases in analyses of databases and theoretical studies adding to rather than replacing traditional methodologies (like observations and field experiments). The representation of women increased over time. There were some differences in the approaches taken by men and women, which requires further investigation.

AbstractUnderstanding how age and body size vary across elevations can provide insights into the evolution of life‐history traits in animals. In the present study, we compared the demographic (using skeletochronology) and morphological traits of the Tibetan toad (Bufo tibetanus) between two populations from different elevational habitats (2650 vs. 3930 m). We found that (1) the mean age and body size of females were significantly greater than those of males in both populations; (2) both sexes of toads from the higher elevation tended to be significantly older in age and larger in body size; (3) there was a significant positive relationship between age and body size within each sex of the toad at both elevations; and (4) growth rates varied between the two populations, with the higher rate observed in the lower‐elevation population. Our results suggested that factors other than age, such as elevation‐associated temperature, influence the observed differences in body size between the two populations. Future research at a broader range of elevations should focus on these factors and evaluate their influence on animal growth patterns.
Energy Transfer Processes in NaBiF4 Nanocrystals Co‐Doped with Tb3+ and Eu3+ Dispersed in Aqueous Solution

Published: June 2024

AbstractThe synthesis of hexagonal NaBiF4 co‐doped with Tb3+ and Eu3+(NaBi0.75−xTb0.25EuxF4; with x=0, 5, 10, 20 and 30) was achieved via a facile and fast precipitation route at 35 °C. Powder X‐ray diffraction (PXRD) and luminescence spectroscopy have been employed to characterize and investigate the materials. The study of luminescence spectroscopy and decay kinetics of the 5D4 excited state of Tb3+ provides the evidence of a Tb3+→Eu3+ energy transfer process. Sodium citrate has been adopted as capping agent to promote a homogeneous dispersion of the materials into water and to protect the inorganic host, which is water sensitive, from direct contact with this molecule. The comparison of luminescence properties between bare and citrate‐capped samples of NaBiF4 co‐doped with Tb3+ and Eu3+ reveals a marked difference in the Tb3+→Eu3+ energy transfer efficiency, which has been tentatively explained on the basis of a different environment surrounding the lanthanide ions in the two families of compounds.

ZIF‐8 decorated FeMo nanoparticles: H2 Production from the catalytic hydrolysis of ammonia‐borane
Authors: Yılmaz Can , Yıldırım Hüseyin Ali , Top Tuba , Yurderi Mehmet , Zahmakıran Mehmet 
Published: June 2024

AbstractAmmonia‐Borane (AB) is considered a promising solid hydrogen storage material due to its high hydrogen content (19.6 wt%) and its use for safe hydrogen transport. The most effective way to produce H2 from AB is to perform the hydrolysis reaction in the presence of a suitable catalyst. In this study, Fe0.2Mo0.8/ZIF‐8 nanocatalyst was synthesized in two steps: (i) synthesis by following the colloidal synthesis technique by thermal decomposition of Mo(CO)6 and Fe(acac)3 in the presence of OM and ODE at high temperatures, and (ii) the resulting colloidal Fe0.2Mo0.8 NPs were decorated into ZIF‐8. The as‐prepared Fe0.2Mo0.8/ZIF‐8 catalyst was identified using advanced characterization techniques such as ICP‐OES, P‐XRD, SEM, SEM–EDX, TEM, TEM‐EDX, XPS, and BET. The catalytic activities of the Fe0.2Mo0.8/ZIF‐8 catalyst in the hydrolysis of AB were investigated in different parameters (temperature, catalyst [Fe0.2Mo0.8] and substrate [H3NBH3] concentration, and recyclability). The results show that high crystallinity Fe0.2Mo0.8 NPs with a uniform 1.31 ± 0.13 nm distribution were formed on the ZIF‐8 surface. Fe0.2Mo0.8/ZIF‐8 catalyst provides a maximum H2 generation rate of 184.2 mLH2 (g catalyst)−1 (min)−1 at 343 K. This uniquely cost‐effective, active and durable Fe0.2Mo0.8/ZIF‐8 catalyst has strong potential for H2‐based fuel cell (PEM: Proton Exchange Membrane) applications where AB is a suitable H2 carrier.Highlights
FeMo NPs were synthesized by a colloidal synthesis method and decorated into ZIF‐8.
FeMo/ZIF‐8 catalyst is an active catalyst in the hydrolysis of AB.
FeMo/ZIF‐8 catalyst showed an initial TOF value of 449.85 mol(H2)·molFe0.2Mo0.8−1·h−1 in the AB hydrolysis at 338 K.
Performance and hydrodynamic study of a new multi‐stage solar photoreactor with immobilized ZnO for synthetic wastewater treatment
Authors: Boutra Belgassim , Sebti Aicha , Mahidine Sarah , Trari Mohamed 
Published: June 2024

AbstractThis study aims to design a new multi‐stage photoreactor with immobilized ZnO and assess its performance in reducing textile wastewater toxicity using solar energy. The electric conductivity measurement is retained as a detection method to obtain the residence time distribution (RTD) function. The RTD is then used to characterize the hydrodynamic behavior of the photoreactor and to evaluate its deviation from the distribution curves of ideal reactors. Solar experiments are conducted to demonstrate the performance of this multistage reactor towards the degradation of a textile azo dye namely Solophenyl Red 3BL (SR 3BL). The influence of the flow rate and the SR 3BL initial concentration (CO) are considered. The variation of the flow rate slightly influences the SR 3BL photodegradation efficiency and it is inversely proportional to its concentration. The study of the reuse of the immobilized catalyst shows that the degradation efficiency of 98% is reached even after multiple photocatalytic cycles. The figure of merit collector area per order was in the range of 35 to 110 . This result provides useful information for scaling up and estimating energy efficiency of the reactor.
Unlocking the potential of low concentration biodiesel blended with green synthesized novel carbon black nanoparticles from Ricinus communis outer shell: An experimental study under different compression ratios and EGR concentrations
Authors: Murugan M. Ananda , Ganesan Nataraj 
Published: June 2024

AbstractThe outer prickly shells of the Ricinus communis (castor plant) have intrigued researchers interested in the synthesis of carbon black (CB) nanoparticles because of their excellent biocompatibility, low toxicity, and widespread availability. Both chemical and physical synthesis methods, such as pyrolysis and ball milling, are employed to obtain the fine‐sized CB nanoparticles. The ball milling process is done for 5 h to reduce the size of the biochar from the pyrolysis process. The as‐synthesized CB nanoparticles are characterized using Fourier transform infrared spectroscopy, x‐ray diffraction, and field emission scanning electron microscopy analysis. The energy dispersive spectrum also confirmed that the nanoparticles are highly composed of carbon and oxygen. CB nanoparticles made from green materials are added to a low‐concentrated biodiesel blend of waste fried edible oil at a rate of 100 ppm. The experiment was performed in a single‐cylinder diesel engine under varying compression ratios (CRs) (16:1–18:1), loads (0–16 kg), and exhaust gas recirculation (EGR) rates (0%, 15%, and 25%). The results revealed that the existence of carbon in nanoparticles increased the mean gas temperature, and the mass fraction burned was also slightly higher than diesel. Raising both CR (16:1–17:1 and 16:1–18:1) and EGR (25%) boosted the cylinder pressure of CBB30 (1.844% and 10.391%, respectively). In contrast, it lowered the net heat release rate (7.88% and 14.56%, respectively). Similar to this, smoke emissions decreased by 6.38% and 15.02%, respectively, at the same CR and EGR parameters. On the other hand, brake thermal efficiency slumped by 7.22% and 10.13% concurrently.

Published: June 2024

AbstractThis paper presents a methodology to minimally modify a ground motion time history to induce collapse in nonlinear single‐degree‐of‐freedom systems (SDOF). The metric used to characterize the modification is the Arias intensity. The proposed procedure is a heuristic extension of a closed‐form solution derived to achieve a target maximum response in linear systems. The methodology is presented as a potential alternative to incremental dynamic analysis (IDA) widely used in earthquake engineering.
Effects of Metabolic Disruption on Lipid Metabolism and Yolk Retention in Zebrafish Embryos
Authors: Boom Rik , Vergauwen Lucia , Knapen Dries 
Published: June 2024

Abstract
A subgroup of endocrine-disrupting chemicals have the ability to disrupt metabolism. These metabolism-disrupting chemicals (MDCs) can end up in aquatic environments and lead to adverse outcomes in fish. Although molecular and physiological effects of MDCs have been studied in adult fish, few studies have investigated the consequences of metabolic disruption in fish during the earliest life stages. To investigate the processes affected by metabolic disruption, zebrafish embryos were exposed to peroxisome proliferator–activated receptor gamma (PPARγ) agonist rosiglitazone, the PPARγ antagonist T0070907, and the well-known environmentally relevant MDC bisphenol A. Decreased apolipoprotein Ea transcript levels indicated disrupted lipid transport, which was likely related to the observed dose-dependent increases in yolk size across all compounds. Increased yolk size and decreased swimming activity indicate decreased energy usage, which could lead to adverse outcomes because the availability of energy reserves is essential for embryo survival and growth. Exposure to T0070907 resulted in a darkened yolk. This was likely related to reduced transcript levels of genes involved in lipid transport and fatty acid oxidation, a combination of responses that was specific to exposure to this compound, possibly leading to lipid accumulation and cell death in the yolk. Paraoxonase 1 (Pon1) transcript levels were increased by rosiglitazone and T0070907, but this was not reflected in PON1 enzyme activities. The present study shows how exposure to MDCs can influence biochemical and molecular processes involved in early lipid metabolism and may lead to adverse outcomes in the earliest life stages of fish.

Published: June 2024

AbstractImmunomodulation has emerged as a promising strategy for promoting bone regeneration. However, designing osteoimmunomodulatory biomaterial that can respond to mechanical stress in the unique microenvironment of alveolar bone under continuous occlusal stress remains a significant challenge. Herein, a wireless piezoelectric stimulation system, namely, piezoelectric hydrogel incorporating BaTiO3 nanoparticles (BTO NPs), is successfully developed to generate piezoelectric potentials for modulating macrophage reprogramming. The piezoelectric stimulation reprograms macrophages towards the M2 phenotype, which subsequently induces osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs). RNA sequencing analysis reveals that piezoelectricity‐modulated macrophage M2 polarization is closely associated with metabolic reprogramming, including increased amino acid biosynthesis and fatty acid oxidation. The composite hydrogel with excellent biocompatibility exhibits immunomodulatory and osteoinductive activities. In a rat model of alveolar bone defects, the piezoelectric hydrogel effectively promotes endogenous bone regeneration at the load‐bearing sites. The piezoelectric‐driven osteoimmunomodulation proposed in this study not only broadens understanding of the mechanism underlying piezoelectric biomaterials for tissue regeneration but also provides new insights into the design and development of next‐generation immunomodulatory biomaterials.
