Authors: Freudenstein David , Lippert Magdalena , Popp Janina Sophie , Aprato Jessica , Wegner Michael , Sock Elisabeth , Haase Stefanie , Linker Ralf A. , González Alvarado María Nazareth
Published: December 2023

Genome-wide association studies identified a single nucleotide polymorphism (SNP) downstream of the transcription factor Sox8, associated with an increased risk of multiple sclerosis (MS). Sox8 is known to influence oligodendrocyte terminal differentiation and is involved in myelin maintenance by mature oligodendrocytes. The possible link of a Sox8 related SNP and MS risk, along with the role of Sox8 in oligodendrocyte physiology prompted us to investigate its relevance during de- and remyelination using the cuprizone model. Sox8−/− mice and wildtype littermates received a cuprizone diet for 5 weeks (wk). Sox8−/− mice showed reduced motor performance and weight compared to wildtype controls. Brains were histologically analysed at the maximum of demyelination (wk 5) and on two time points during remyelination (wk 5.5 and wk 6) for oligodendroglial, astroglial, microglial and myelin markers. We identified reduced proliferation of oligodendrocyte precursor cells at wk 5 as well as reduced numbers of mature oligodendrocytes in Sox8−/− mice at wk 6. Moreover, analysis of myelin markers revealed a delay in remyelination in the Sox8−/− group, demonstrating the potential importance of Sox8 in remyelination processes. Our findings present, for the first time, compelling evidence of a significant role of Sox8 in the context of a disease model.

Authors: Salabi Fatemeh , Vazirianzadeh Babak , Baradaran Masoumeh
Published: December 2023

Scorpion venoms contain bioactive peptides and proteins. Some, can be used for pharmaceutical purposes. So, identification of venom proteins matters because, in addition to determining the function of the toxins can also be an excellent guide to developing new drugs. Here, we got transcriptome of venom glands from four Iranian scorpion species, including Hemsicorpius lepturus, Mesobuthus eupeus, Andructunus crassicuada, and Hottentotta saulcyi using cDNA library synthesis and high-throughput transcriptomic analysis of the venom glands. In a comparative way, we identified the cDNA encoding isoforms of subunits (alpha and beta) of BotLVP1/BmLVP1-like protein in the venom gland of three species except for H. lepturus. Characterization and structure determination of the LVP1_like proteins combined with gene map analysis provided evidence of the existence of some isoforms of LVP1_like proteins, encoded by genes with two exons and one intron, which can be classified in CSαβ superfamily in the venom gland of three Iranian scorpion species. According to the high similarity with BotLVP1 and BmLVP1, these proteins could also be potent to mediate cholesterol homeostasis. However, further research is needed to prove it, and this study just may lay the foundation lead to light up this way.
Patient-specific computational models of retinal prostheses
Authors: Kish Kathleen E. , Yuan Alex , Weiland James D.
Published: December 2023

Retinal prostheses stimulate inner retinal neurons to create visual perception for blind patients. Implanted arrays have many small electrodes. Not all electrodes induce perception at the same stimulus amplitude, requiring clinicians to manually establish a visual perception threshold for each one. Phosphenes created by single-electrode stimuli can also vary in shape, size, and brightness. Computational models provide a tool to predict inter-electrode variability and automate device programming. In this study, we created statistical and patient-specific field-cable models to investigate inter-electrode variability across seven epiretinal prosthesis users. Our statistical analysis revealed that retinal thickness beneath the electrode correlated with perceptual threshold, with a significant fixed effect across participants. Electrode-retina distance and electrode impedance also correlated with perceptual threshold for some participants, but these effects varied by individual. We developed a novel method to construct patient-specific field-cable models from optical coherence tomography images. Predictions with these models significantly correlated with perceptual threshold for 80% of participants. Additionally, we demonstrated that patient-specific field-cable models could predict retinal activity and phosphene size. These computational models could be beneficial for determining optimal stimulation settings in silico, circumventing the trial-and-error testing of a large parameter space in clinic.
Regionalization of cell types in silk glands of Larinioides sclopetarius suggest that spider silk fibers are complex layered structures
Authors: Sonavane Sumalata , Westermark Per , Rising Anna , Holm Lena
Published: December 2023

In order to produce artificial silk fibers with properties that match the native spider silk we likely need to closely mimic the spinning process as well as fiber architecture and composition. To increase our understanding of the structure and function of the different silk glands of the orb weaver Larinioides sclopetarius, we used resin sections for detailed morphology, paraffin embedded sections for a variety of different histological stainings, and a histochemical method for localization of carbonic anhydrase activity. Our results show that all silk glands, except the tubuliform glands, are composed of two or more columnar epithelial cell types, some of which have not been described previously. We observed distinct regionalization of the cell types indicating sequential addition of secretory products during silk formation. This means that the major ampullate, minor ampullate, aciniform type II, and piriform silk fibers most likely are layered and that each layer has a specific composition. Furthermore, a substance that stains positive for polysaccharides may be added to the silk in all glands except in the type I aciniform glands. Active carbonic anhydrase was found in all silk glands and/or ducts except in the type I aciniform and tubuliform glands, with the strongest staining in aggregate glands and their ductal nodules. Carbonic anhydrase plays an important role in the generation of a pH gradient in the major ampullate glands, and our results suggest that some other glands may also harbor pH gradients.
Machine learning and atomistic origin of high dielectric permittivity in oxides
Authors: Shimano Yuho , Kutana Alex , Asahi Ryoji
Published: December 2023

Discovering new stable materials with large dielectric permittivity is important for future energy storage and electronics applications. Theoretical and computational approaches help design new materials by elucidating microscopic mechanisms and establishing structure–property relations. Ab initio methods can be used to reliably predict the dielectric response, but for fast materials screening, machine learning (ML) approaches, which can directly infer properties from the structural information, are needed. Here, random forest and graph convolutional neural network models are trained and tested to predict the dielectric constant from the structural information. We create a database of the dielectric properties of oxides and design, train, and test the two ML models. Both approaches show similar performance and can successfully predict response based on the structure. The analysis of the feature importance allows identification of local geometric features leading to the high dielectric permittivity of the crystal. Dimensionality reduction and clustering further confirms the relevance of descriptors and compositional features for obtaining high dielectric permittivity.

Published: December 2023

Public holidays have been associated with SARS-CoV-2 incidence surges, although a firm link remains to be established. This association is sometimes attributed to events where transmissions occur at a disproportionately high rate, known as superspreading events. Here, we describe a sudden surge in new cases with the Omicron BA.1 strain amongst higher education students in Belgium. Contact tracers classed most of these cases as likely or possibly infected on New Year's Eve, indicating a direct trigger by New Year celebrations. Using a combination of contact tracing and phylogenetic data, we show the limited role of superspreading events in this surge. Finally, the numerous simultaneous transmissions allowed a unique opportunity to determine the distribution of incubation periods of the Omicron strain. Overall, our results indicate that, even under social restrictions, a surge in transmissibility of SARS-CoV-2 can occur when holiday celebrations result in small social gatherings attended simultaneously and communitywide.

Published: December 2023

In this report, we present the development of a copper nanofiber network-based microheater, designed for applications in electron microscopes, gas sensing, and cell culture platforms. The seed layer, essential for electroless deposition, was fabricated through the electrospinning of a palladium-contained polyvinylpyrrolidone solution followed by a heat treatment. This process minimized the contact resistance between nanofibers. We successfully fabricated a microheater with evenly distributed temperature by controlling the electrospinning time, heat treatment conditions, and electroless deposition time. We assessed the electrical and thermal characteristics of the microheater by examining the nanofiber density, sheet resistance, and transmittance. The microheater’s performance was evaluated by applying current, and we verified its capacity to heat up to a maximum of 350 °C. We further observed the microheater’s temperature distribution at varying current levels through an infrared camera. The entire manufacturing procedure takes place under normal pressure, eliminating the need for masking or etching processes. This renders the method easily adaptable to the mass production of microdevices. The method is expected to be applicable to various materials and sizes and is cost-effective compared to commercially produced microheaters developed through microelectromechanical system processes, which demand complex facilities and high cost.
The mechanism analysis on the farmers’ motivation of using the quality traceability system based on TAM-ECM model
Authors: He Wang , Qi Chunjie , Ding Liang
Published: December 2023

The quality traceability system for agricultural product plays an important role in tracing the production history or flow of agricultural products in China. At present, the quality traceability system is facing the problem of limited coverage and promotion. Understanding the continuous usage behavior of users can help solve this problem. This study constructed a model integrating TAM-ECM to analyze the mechanisms affecting the continuous usage intention and behavior of users of the quality traceability system, using PLS analysis method and survey data from 197 users of the GanNan navel orange quality traceability system with a usage time of up to two years. The results show that both satisfaction and usage habits directly promote the continuous usage of the quality traceability system. Lowering transaction costs significantly improves perceived value and satisfaction, and has a greater direct impact on satisfaction. Expectation confirmation level has a positive effect on perceived value, and lowering transaction costs also enhances perceived value. Perceived value、transaction cost, and satisfaction are important factors driving the continuous usage of the quality traceability system by users. The research findings provide a reference basis for the government to develop policies to attract users to use the quality traceability system for agricultural product.
Imaging and AI based chromatin biomarkers for diagnosis and therapy evaluation from liquid biopsies
Authors: Challa Kiran , Paysan Daniel , Leiser Dominic , Sauder Nadia , Weber Damien C. , Shivashankar G. V.
Published: December 2023

Multiple genomic and proteomic studies have suggested that peripheral blood mononuclear cells (PBMCs) respond to tumor secretomes and thus could provide possible avenues for tumor prognosis and treatment evaluation. We hypothesized that the chromatin organization of PBMCs obtained from liquid biopsies, which integrates secretome signals with gene expression programs, provides efficient biomarkers to characterize tumor signals and the efficacy of proton therapy in tumor patients. Here, we show that chromatin imaging of PBMCs combined with machine learning methods provides such robust and predictive chromatin biomarkers. We show that such chromatin biomarkers enable the classification of 10 healthy and 10 pan-tumor patients. Furthermore, we extended our pipeline to assess the tumor types and states of 30 tumor patients undergoing (proton) radiation therapy. We show that our pipeline can thereby accurately distinguish between three tumor groups with up to 89% accuracy and enables the monitoring of the treatment effects. Collectively, we show the potential of chromatin biomarkers for cancer diagnostics and therapy evaluation.
Evolution of lysine-specific demethylase 1 and REST corepressor gene families and their molecular interaction
Authors: Olivares-Costa Montserrat , Oyarzún Gianluca Merello , Verbel-Vergara Daniel , González Marcela P. , Arancibia Duxan , Andrés María E. , Opazo Juan C.
Published: December 2023

Lysine-specific demethylase 1A (LSD1) binds to the REST corepressor (RCOR) protein family of corepressors to erase transcriptionally active marks on histones. Functional diversity in these complexes depends on the type of RCOR included, which modulates the catalytic activity of the complex. Here, we studied the duplicative history of the RCOR and LSD gene families and analyzed the evolution of their interaction. We found that RCOR genes are the product of the two rounds of whole-genome duplications that occurred early in vertebrate evolution. In contrast, the origin of the LSD genes traces back before to the divergence of animals and plants. Using bioinformatics tools, we show that the RCOR and LSD1 interaction precedes the RCOR repertoire expansion that occurred in the last common ancestor of jawed vertebrates. Overall, we trace LSD1-RCOR complex evolution and propose that animal non-model species offer advantages in addressing questions about the molecular biology of this epigenetic complex.

Published: December 2023

Fibrogenesis is part of a normal protective response to tissue injury that can become irreversible and progressive, leading to fatal diseases. Senescent cells are a main driver of fibrotic diseases through their secretome, known as senescence-associated secretory phenotype (SASP). Here, we report that cellular senescence, and multiple types of fibrotic diseases in mice and humans are characterized by the accumulation of iron. We show that vascular and hemolytic injuries are efficient in triggering iron accumulation, which in turn can cause senescence and promote fibrosis. Notably, we find that senescent cells persistently accumulate iron, even when the surge of extracellular iron has subdued. Indeed, under normal conditions of extracellular iron, cells exposed to different types of senescence-inducing insults accumulate abundant ferritin-bound iron, mostly within lysosomes, and present high levels of labile iron, which fuels the generation of reactive oxygen species and the SASP. Finally, we demonstrate that detection of iron by magnetic resonance imaging might allow non-invasive assessment of fibrotic burden in the kidneys of mice and in patients with renal fibrosis. Our findings suggest that iron accumulation plays a central role in senescence and fibrosis, even when the initiating events may be independent of iron, and identify iron metabolism as a potential therapeutic target for senescence-associated diseases.

Accelerating active catalyst discovery: a probabilistic prediction-based screening methodology with applications in dry reforming of methane
Authors: Park Hyundo , Roh Jiwon , Cho Hyungtae , Ro Insoo , Kim Junghwan
Published: December 2023

Dry reforming of methane (DRM) is a promising technology for syngas production from CH4 and CO2. However, discovering feasible and efficient catalysts remains challenging despite recent advancements in machine learning. Herein, we present a novel probabilistic prediction-based, high-throughput screening methodology that demonstrates outstanding performance, with a coefficient of determination (R2) of 0.936 and root-mean-square error (RMSE) of 6.66. Additionally, experimental validation was performed using 20 distinct catalysts to ensure the accurate verification of the model, 17 of which were previously unreported combinations. Our model accurately predicts CH4 conversion rates and probability values by considering catalyst design, pretreatment, and operating variables, providing reliable insights into catalyst performance. The proposed probabilistic prediction-based screening methodology, which we introduce for the first time in the field of catalysis, holds significant potential for accelerating the discovery of catalysts for DRM reactions and expanding their application scope in other crucial industrial processes. Thus, the methodology effectively addresses a key challenge in the development of active catalysts for energy and environmental research.

Low‐carbon economic optimal operation strategy of rural multi‐microgrids based on asymmetric Nash bargaining
Authors: Qin Minglei , Xu Qingshan , Liu Wei , Xu Ziming
Published: December 2023

The multi‐microgrids operation can greatly improve the proportion of renewable energy integration and power reliability of rural microgrids through energy trading between adjacent microgrids. Therefore, this paper proposes an optimization method for the low‐carbon economic operation of rural microgrids which contain wind power, photovoltaic, biogas, and other common rural renewable energy sources. Using the asymmetric Nash bargaining model which can form the non‐linear energy mapping function to quantify the bargaining power of each microgrid to establish the multi‐microgrids energy trading model, and the non‐convex trading optimization problem is equivalently transformed into two convex optimization subproblems, subproblem 1 is microgrids alliance costs containing the emission costs, and subproblem 2 is cooperative benefits distribution. Then, the accelerated Alternating Direction Method of Multipliers (ADMM) method is used to solve subproblem 1 and subproblem 2, respectively, and the privacy of transaction information is also protected. The results show that: compared with the single‐microgrid operation, the combined operation of rural multi‐microgrids with biogas can greatly improve the renewable energy consumption rate, reduce carbon emission, and improve the profit income of the alliance and each microgrid. Meanwhile, the accelerated ADMM algorithm used can greatly improve the solution speed.

Authors: Lou Fei , Guan Jing , Lu Wensai
Published: December 2023

To replace the manual labour involved in pipe dredging, this study proposes an extensible differential‐speed helical drive pipe dredging robot. The robot can be released in an inspection well to remove silt from a sewer pipe for routine maintenance. This robot consists of a differential drive system, an extensible helical drive element, a dredging plate, and a retractable feed screw. The extensible helical drive element is used to address the problem of diameter differences between the inspection well, sewage well, and drainpipe. The problem of dynamical dredging working conditions is studied by a detailed design of mechanical system. To analyze the operational process of the proposed robot, a virtual prototype is established using the ADAMS software. The simulation results show that the proposed robot can achieve the slurry‐flow operating state because of its reasonable structure and cutting, mixing, and conveying silt functions. The result presented in this study can help to improve energy efficiency and provide technical assistance for same type robots.
Numerical flow noise simulation of an axial fan with a Lattice-Boltzmann solver
Authors: Antoniou Evangelos , Romani Gianluca , Jantzen Andreas , Czwielong Felix , Schoder Stefan
Published: December 2023

In this paper, a transient and compressible solver based on the Lattice-Boltzmann Method/Very Large Eddy Simulation (LBM/VLES) approach is employed to predict unsteady flow physics and flow-induced noise generation of a low-pressure axial fan. Aerodynamic and aeroacoustic measurements provided by the European Acoustics Association (EAA) benchmark platform are used for validation purposes. Boundary and design operating conditions are applied to the numerical model to replicate the experimental setup. Simulation and experimental data are compared, showing an excellent agreement in terms of fan efficiency with less than 1% deviation, as well as broadband and tonal noise within 0.7 dBA in terms of overall sound pressure level. An advanced post-processing analysis is performed to shed light on the noise generation mechanism in tip clearance. It is observed that both fine random turbulent structures and large coherent vortices are generated in the tip gap. The continuous impingement of the fine turbulence with the following blades and the blade itself is responsible for the radiation of broadband noise, while the interaction between the large coherent tip vortices, spinning at a lower angular velocity with respect to the fan shaft, and the following blades leads to the generation of narraowband peaks at sub-harmonics of the blade-passing frequencies. Finally, a beamforming analysis further confirms that the main noise sources are located in the blade tip clearance and tip regions.

Published: December 2023

Bacterial cellulose (BC) is produced by aerobic bacteria through oxidative fermentation in synthetic and non-synthetic mediums. Several mediums reported to be used as BC formation mediums are coconut water and soybean-boiled wastewater. Carbon sources are needed to optimize the BC formation process. Recent study has implemented a real-time image processing approach for monitoring BC formation. This study aimed to investigate the correlation between variables that influence the fermentation and to determine the kinetic model of BC formation using an image processing approach with the variation of carbon sources during the fermentation. The results showed that the correlation between fermentation time and thickness had the highest percentage for glucose, sucrose, and mannitol mediums. The kinetic observation of BC formation in the medium using glucose, sucrose, and mannitol followed the Gompertz model equation, with the medium using sucrose having the fastest rate of increase at the 44thhour, followed by the medium using mannitol at the 112thhour, and the medium using glucose at the 149thhour.

Therefore, this study aims to analyze the erodibility index at each different slope and to evaluate the effect of erodibility on the potential productivity of agricultural land in terms of soil fertility at the research location. Data analysis was carried out quantitatively and qualitatively. Field measurements and laboratory tests were carried out to collect landscape characteristics and soil data, qualitative measurements with the Dry Soil Test Kit (PUTK) were used to measure potential soil fertility. Data processing using the Stepwise-Regression method was carried out to determine the factors that most influence the erodibility index at the research location, and crosstabulation analysis was carried out on erodibility and soil fertility levels. The results showed that the erodibility level at the research location was mostly moderate with the erodibility index in the very gentle slope ranging between 0.17-0.33, in the gentle slope ranging between 0.08-0.16, in the slightly steep slope class ranging between 0.21-0.24, in the steep slope class it ranges from 0.12-0.61. The factors that most influence the erodibility index at the research location is % Dust, % Clay, Organic Material, and Permeability. Based on a qualitative assessment of soil fertility, the productivity potential of agricultural land in the study area is in the low category.

In this study we investigated the effect of three kinds of palm oil product (refined bleached deodorized palm oil (RBDPO), red palm oil (RPO) and palm kernel oil (PKO)) on the serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), and liver color of rats in fed high-fat diet, and compare it with beef tallow and corn oil. Growing male SD rats were fed a high-fat diet (20% fat) for 13 weeks, divided into 2 groups (with and without azoxymethane (AOM)). Dietary corn oil showed the lowest serum SGOT and SGPT (p < 0.05) both in the AOM and Non-AOM groups. Beef tallow diet caused the highest level of serum SGOT and SGPT followed by PKO, RPO, and RBDPO respectively (p < 0.05). The serum SGOT and SGPT were not affected by the AOM treatment. Although the liver color from the AOM group was relatively darker than the non-AOM group, in general the fat sources did not have a significant effect on liver color.
Adjectivized Grammatical Metaphors in Daily Chinese Conversation
Authors: Li Penglin
Published: December 2023

This paper investigates the phenomenon of adjectival grammatical metaphor in everyday Chinese conversation, with the aim of determining its development and its relation to vocabulary structure. The results show that the verb phrase is one of the main sources of adjectival grammatical metaphors. The combination of adjectival phrases and nouns is a form of ‘verb phrase consists of verb + adjective’, which is commonly used in conversation situations. Moreover, vocabulary structure and lexicality are the major factors that affect the expression of adjectival grammar metaphor and its developing mode.
A Study of the Value of the Human Voice in the Context of Body Embodiment
Authors: Liu Li-ping
Published: December 2023

The idea that “the human voice has a feature of embodiment” was proposed by Mr. Xue Yibing, a Chinese researcher who belongs to a member of the Institute of Music, China Academy of Art. Such a no-tion is not only strange but also familiar. In this context, this paper will borrow the concept of "the origin of musical beauty is the human voice" and combine it with Husserl’s view of "To the things themselves" in phenomenology. Under this circumstance, the embodiment of the human voice would be understood from the human body and sound itself, and the existence value and aesthetic value of the human voice it brings, that is, from the current value, it proves the subjectivity, spiritual embodiment and emotional preservation of human beings; from the aesthetic value, it recognizes non-real objects, brings dynamic manifestation and embodies aesthetic imagery. The inspiration of the human voice in contemporary art creation is further ob-tained: the understanding of tradition and innovation in the human voice, the use of voice to integrate the single and multiple, the human voice to carry the individual and society, the human voice to coordinate the reality and transcendence, which gives the human voice in the new era more profound connotation and sig-nificance.
The relationship between sleep length and depression level in older adults: The masking effect of education level
Authors: Chai Yulin , Luo Sheng
Published: December 2023

Depression is a prevalent mental health issue that affects many people around the world, has a serious impact on global public health, and causes significant economic loss and social burden. There is evidence that sleep length is strongly associated with depression levels, and that sleep length is associated with education levels in different populations. This study found that older adults who lacked sleep length were more depressed, while education level acted as a masking effect between sleep length and depression in older adults. Therefore, it is important to focus on the sleep length of older adults to ensure that they get enough sleep for good health. Further consideration should be given to recommending different specific interventions for older adults with different education levels in order to better reduce the risk of depression in older adults.

[Philosophy Buddhism] A First Look at the World of Information - Understanding Information from the Buddhist Perspective
Authors: Ma Ruguo
Published: December 2023

The information revolution is undoubtedly one of the most important technological achievements of human society; however, there is no consensus among scientists about what information is. What is information? What are the characteristics of information? What is the relationship between information and signals and between information and consciousness? In this study, we try to answer these questions from the perspective of Buddhism. We consider information to be the Buddha’s sambhogakāya, similar to the Buddha’s dharma body, and it is considered to be beyond time and space. Information is “not produced, not destroyed, not defiled, not pure, not increase, and not diminish.” By studying these characteristics of information, the connections between traditional Buddhism and modern technology may be determined, and it can provide insights for the human society to better understand truth.

An Empirical Study on the Federal Law Redundancy Rate — Based on the United States Code
Authors: Chen Ruiyang
Published: December 2023

Whether there are too many laws is a perennial debate that has drawn interest from a variety of sources. The quality and rate of exploitation of legislative resources are important determinants of the redundancy rate of legislation. This paper develops an empirical research procedure to determine the legal redundancy rate by statistically sampling the use of legal articles, including two calculation indices, namely usage rate of legal articles judgments and the overall legal articles usage rate, in order to address the question "Are there too many laws". The empirical study's data analysis led to the conclusion that while the overall citation rate for the law is high, the utilization rate for legal articles in actual situations is relatively low and the redundancy rate for legal articles is high. The research also highlights areas where the empirical investigation should be strengthened, such as additional classification of the sample items and content text mining. For the legal community, the general public, and lawmakers, the findings have significant ramifications.
