Abstract: En | Text: En | PDF: En

Visible light communication is a present technology which allows data to be transmitted by modulating information onto a light source. It has many advantages over traditional radio frequency communication and up to 10,000 times larger bandwidth. Many existing research in visible light communication assumes a synchronized channel, however, this is not always easily achieved. This paper proposes a novel synchronized VLC system with the potential to ensure reliable communication in both intra- and inter-vehicle communication. The protocol achieves synchronization at the symbol level using the transistor-transistor logic protocol and achieves frame synchronizations with markers. Consequently, the deployment of the system in both intra- and inter-vehicle communication may present numerous advantages over existing data transmission processes. A practical application where visible light communication is used for media streaming is also previewed. In addition, various regions of possible data transmission are determined to infer forward error correction schemes to ensure reliable communication.

Abstract Objective To investigate the diagnostic efficacy of serum IL-33 single indicator and combined indicators for asthma in children. Methods 132 children were initially diagnosed with asthma during acute exacerbation and 100 healthy children were included. Serum IL-33 concentration differences were compared between asthmatic and normal children. Correlations between IL-33 with pulmonary function parameters, FeNO, peripheral blood EOS counts and serum total IgE were analyzed in asthmatic children. ROC curves were used to assess IL-33 diagnostic efficacy and its combined indicators. To prevent overfitting of the predictive model, the hold-out cross-validation method was used. Results (1) Serum IL-33 concentrations were significantly higher in children with asthma than in normal children (p < 0.001). (2) IL-33 concentration was negatively correlated with FVC z-score, FEV1 z-score and FEF75% z-score in asthmatic children (p < 0.05). (3) The area under the ROC curve of IL-33 was 0.821, which was higher than those of FeNO, FVC z-score, and FEV1 z-score. (4) Cross-validation of the combined indicators showed that IL-33 significantly improved asthma diagnostic efficacy. The combination of IL-33, FEF75% z-score, and FeNO showed the highest diagnostic efficacy, with the AUC, sensitivity, and specificity of the combined indicator being 0.954, 90.1%, and 89. 0%, respectively, and good extrapolation of the predictive model. Conclusion Serum IL-33 is higher in children with asthma and increases with the severity of pulmonary ventilation obstruction. A single indicator of serum IL-33 demonstrates moderate diagnostic accuracy, and its combination with FEF75% z-score and FeNO significantly improves the diagnostic accuracy in childhood asthma.

Abstract Objective: This study aimed to develop and internally validate a prediction model for estimating the risk of spontaneous abortion in early pregnancy. Methods: This prospective cohort study included 9,895 pregnant women who received prenatal care at a maternal health facility in China from January 2021 to December 2022. Data on demographics, medical history, lifestyle factors, and mental health were collected. A multivariable logistic regression analysis was performed to develop the prediction model with spontaneous abortion as the outcome. The model was internally validated using bootstrapping techniques, and its discrimination and calibration were assessed. Results: The spontaneous abortion rate was 5.95% (589/9,895) 1. The final prediction model included nine variables: maternal age, history of embryonic arrest, thyroid dysfunction, polycystic ovary syndrome, assisted reproduction, exposure to pollution, recent home renovation, depression score, and stress score 1. The model showed good discrimination with a C-statistic of 0.88 (95% CI 0.87‒0.90) 1, and its calibration was adequate based on the Hosmer-Lemeshow test (p = 0.27). Conclusions: The prediction model demonstrated good performance in estimating spontaneous abortion risk in early pregnancy based on demographic, clinical, and psychosocial factors. Further external validation is recommended before clinical application.

Abstract: Feuerbach is one of the representatives of the young Hegelian. In the book The German Ideology, Marx analyzed the state of German ideology at that time through the comparison between materialism and idealism, and criticized him. Marx criticized Feuerbach’s conception of “human nature”, the limitations of materialism, his understanding of “reality” and his understanding of historical relations, starting from real people and their production. This critique laid the foundation for the development of Marxist materialist historiography.

Resumen: Feuerbach es uno de los representantes Del joven hegeliano. En el libro la ideología alemana, Marx analizó el estado de la ideología alemana en ese momento a través de la comparación entre materialismo e idealismo, y lo criticó. Marx criticó la concepción de Feuerbach de la “naturaleza humana”, las limitaciones del materialismo, su concepción de la “realidad” y su comprensión de las relaciones históricas, partiendo de las personas reales y su producción. Esta crítica sentó las bases para el desarrollo de la historiografía materialista marxista.

Abstract: En | Text: En | PDF: En

Abstract Objective This retrospective study aimed to analyze the clinical efficacy of two regenerative surgical methods — Bio-Oss granules combined with barrier membranes and Bio-Oss Collagen alone — and to help clinicians achieve better periodontal regeneration outcomes in the specific periodontal condition. Methodology Patients who underwent periodontal regeneration surgery from January 2018 to April 2022 were retrospectively screened, and their clinical and radiographic outcomes at 6 months postoperatively were analyzed. The probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), gingival recession (GR), distance from the cemento-enamel junction to the bottom of the bone defect (CEJ-BD), and depth of intrabony defects (INFRA) were recorded before the operation (T0) and 6 months after it (T1), and subsequently compared. Results In total, 143 patients were included — 77 were placed in the Bio-Oss group and 66 were placed in the Bio-Oss Collagen group. All indicators, including PD and CAL at T1, showed significant differences compared to baseline, for both groups (P<0.001). PD reduction was greater in the group receiving the Bio-Oss Collagen treatment (P=0.042). Furthermore, in cases when the baseline PD range was 7-11 mm and the age range was 35-50 years, PD reduction was more significant for patients receiving the Bio-Oss Collagen treatment (P=0.031, 0.023). A linear regression analysis indicated that postoperative PD and CAL were positively correlated with baseline values, and that the efficacy tended to decrease with increasing age. Conclusion Both the use of Bio-Oss Collagen alone and the use of Bio-Oss granules combined with barrier membranes resulted in significant effects in the treatment of periodontal intrabony defects. The Bio-Oss Collagen treatment generated more improvements in PD than the Bio-Oss granules combined with barrier membranes, particularly within the baseline PD range of 7-11 mm and the 35-50 years age group. Additionally, age was the main factor influencing the effectiveness of regenerative surgery for intrabony defects: older individuals exhibited fewer improvements.

Abstract Background Sensorineural hearing loss (SNHL) poses a major threat to both physical and mental health; however, there is still a lack of effective drugs to treat the disease. Recently, novel biological therapies, such as mesenchymal stem cells (MSCs) and their products, namely, exosomes, are showing promising therapeutic potential due to their low immunogenicity, few ethical concerns, and easy accessibility. Nevertheless, the precise mechanisms underlying the therapeutic effects of MSC-derived exosomes remain unclear. Results Exosomes derived from MSCs reduced hearing and hair cell loss caused by neomycin-induced damage in models in vivo and in vitro. In addition, MSC-derived exosomes modulated autophagy in hair cells to exert a protective effect. Mechanistically, exogenously administered exosomes were internalized by hair cells and subsequently upregulated endocytic gene expression and endosome formation, ultimately leading to autophagy activation. This increased autophagic activity promoted cell survival, decreased the mitochondrial oxidative stress level and the apoptosis rate in hair cells, and ameliorated neomycin-induced ototoxicity. Conclusions In summary, our findings reveal the otoprotective capacity of exogenous exosome-mediated autophagy activation in hair cells in an endocytosis-dependent manner, suggesting possibilities for deafness treatment. SNHL (SNHL health however disease Recently therapies (MSCs products namely immunogenicity concerns accessibility Nevertheless MSCderived MSC unclear neomycininduced neomycin induced vitro addition effect Mechanistically formation survival ototoxicity summary exosomemediated exosome mediated endocytosisdependent endocytosis dependent manner treatment

Abstract: En | Text: En | PDF: En

Abstract To solve the problem that the mechanical behavior of undisturbed loess in seasonally frozen soil area is affected by freeze-thaw action, triaxial shear tests of undisturbed loess under freeze-thaw condition were carried out. The results show that the mechanical properties of undisturbed loess are greatly affected by factors including freeze-thaw process, water content, natural density and confining pressure. Freeze-thaw action has a certain impact on the failure surface shape and stress-strain curve. Before and after freeze-thaw, the shape of the shear failure surface is complex, including single oblique failure surface, double oblique failure surface, vertical failure surface, X-shaped failure surface, bulging failure, etc. And under the conditions of low water content, low confining pressure and high dry density, the stress-strain curve tends to be softened. Conversely, the curve tends to harden. Freeze-thaw action can make the stress-strain curve transition from softening to hardening. In addition, the freeze-thaw action significantly weakens the failure strength, shear strength, cohesion, initial tangent modulus and failure ratio of undisturbed soil, but does not change the internal friction angle obviously. Also, the heterogeneity of natural soil is also an important factor affecting the mechanical parameters, failure surface shape and stress-strain curve of undisturbed loess. freezethaw freeze thaw out process content Freezethaw Freeze stressstrain stress strain freezethaw, thaw, complex Xshaped X shaped etc softened Conversely harden hardening addition strength cohesion obviously Also parameters

ABSTRACT Objective: The optimal target for blood glucose concentration in critically ill patients is unclear. We will perform a systematic review and meta-analysis with aggregated and individual patient data from randomized controlled trials, comparing intensive glucose control with liberal glucose control in critically ill adults. Data sources: MEDLINE®, Embase, the Cochrane Central Register of Clinical Trials, and clinical trials registries (World Health Organization, clinical trials.gov). The authors of eligible trials will be invited to provide individual patient data. Published trial-level data from eligible trials that are not at high risk of bias will be included in an aggregated data meta-analysis if individual patient data are not available. Methods: Inclusion criteria: randomized controlled trials that recruited adult patients, targeting a blood glucose of ≤ 120mg/dL (≤ 6.6mmol/L) compared to a higher blood glucose concentration target using intravenous insulin in both groups. Excluded studies: those with an upper limit blood glucose target in the intervention group of > 120mg/dL (> 6.6mmol/L), or where intensive glucose control was only performed in the intraoperative period, and those where loss to follow-up exceeded 10% by hospital discharge. Primary endpoint: In-hospital mortality during index hospital admission. Secondary endpoints: mortality and survival at other timepoints, duration of invasive mechanical ventilation, vasoactive agents, and renal replacement therapy. A random effect Bayesian meta-analysis and hierarchical Bayesian models for individual patient data will be used. Discussion: This systematic review with aggregate and individual patient data will address the clinical question, ‘what is the best blood glucose target for critically ill patients overall?’ Protocol version 0.4 - 06/26/2023 PROSPERO registration: CRD42021278869

RESUMO Objetivo: Não está claro qual é a meta ideal de concentração de glicose no sangue em pacientes em estado grave. Realizaremos uma revisão sistemática e uma metanálise com dados agregados e de pacientes individuais de estudos controlados e randomizados, comparando o controle intensivo da glicose com o controle liberal da glicose em adultos em estado grave. Fontes de dados: MEDLINE®, Embase, Cochrane Central Register of Clinical Trials e registros de ensaios clínicos (Organização Mundial da Saúde, clinical trials.gov). Os autores dos estudos qualificados serão convidados a fornecer dados individuais de pacientes. Os dados publicados em nível de ensaio qualificado que não apresentem alto risco de viés serão incluídos em uma metanálise de dados agregados se os dados individuais de pacientes não estiverem disponíveis. Métodos: Critérios de inclusão: ensaios clínicos controlados e randomizados que recrutaram pacientes adultos, com meta de glicemia ≤ 120mg/dL (≤ 6,6mmol/L) comparada a uma meta de concentração de glicemia mais alta com insulina intravenosa em ambos os grupos. Estudos excluídos: aqueles com meta de glicemia no limite superior no grupo de intervenção > 120mg/dL (> 6,6mmol/L), ou em que o controle intensivo de glicose foi realizado apenas no período intraoperatório, e aqueles em que a perda de seguimento excedeu 10% até a alta hospitalar. Desfecho primário: Mortalidade intra-hospitalar durante a admissão hospitalar. Desfechos secundários: Mortalidade e sobrevida em outros momentos, duração da ventilação mecânica invasiva, agentes vasoativos e terapia de substituição renal. Utilizaremos metanálise bayesiana de efeito randômico e modelos bayesianos hierárquicos para dados individuais de pacientes. Discussão: Essa revisão sistemática com dados agregados e de pacientes individuais abordará a questão clínica: Qual é a melhor meta de glicose no sangue de pacientes graves em geral?

Abstract Women’s Suffrage Centennial has arrived in a culturally divisive time in the United States as well as in a high-stakes presidential election year. All this is accompanied with the emergence of «Black Lives Matter» movement on a global-scale in the wake of the African American man George Floyd’s death under the knees of white police officers. In an «I cannot breathe» America at a new cultural awakening moment, is the Centennial a divider or unifier for American women in 2020? This article aims to answer the question by revisiting the 14th and 15th Amendments to the Constitution and iconic figures like Elizabeth Cady Stanton, Susan B. Anthony, Frederick Douglass, William Edward Burghardt W.E.B. Du Bois, and Mary Church Terrell. In an interdisciplinary approach anchored in both historical and cultural studies, the article scrutinizes the split between the two visceral elements pertinent to cultural identity -gender and race- in Women’s Suffrage Movement, draws a pattern of their intersection, and maps out a «double consciousness» (to borrow W.E.B. Du Bois’ term). The article argues that the women’s suffrage movement was indeed a gigantic step towards the American ideal of gender equality, but it fell short of racial equality. There is a mixed legacy to embrace and to reevaluate at the same time. Therefore, Women’s Suffrage Centennial should not and cannot be a single-issue gender celebration, nor a one-size-fits-all symphony, but a landmark occasion for an intimate and nuanced dialog between gender and race. The article suggests that the Centennial should not only celebrate white American suffragists but should be an opportunity to make a historic step to cross the color line that has cutoff African American women, as well as women of color from other races, ethnicities, and heritages from the power center.

Resumen El Centenario del Sufragio Femenino ha llegado en un momento culturalmente divisivo en los Estados Unidos, así como en un año de elecciones presidenciales de alto riesgo. Todo esto va acompañado del surgimiento del movimiento «Black Lives Matter» (La vida de las personas negras importa) a escala mundial tras la muerte del afroamericano George Floyd bajo las rodillas de policías blancos. En una Estados Unidos de América en la que «no puedo respirar» es un nuevo momento de despertar cultural ¿Es el Centenario un divisor o unificador para las mujeres estadounidenses en 2020? Este artículo tiene como objetivo responder a la pregunta a partir de la revisión de las Enmiendas 14 y 15 a la Constitución y del pensamiento de figuras icónicas como Elizabeth Cady Stanton, Susan B. Anthony, Frederick Douglass, William Edward Burghardt Du Bois y Mary Church Terrell. Con un enfoque interdisciplinario anclado en los estudios históricos y culturales, el artículo analiza la división entre los dos elementos viscerales pertinentes a la identidad cultural (género y raza2) en el Movimiento por el Sufragio de la Mujer, dibuja un patrón de su intersección y traza una «doble conciencia» (tomando prestado el término de W.E.B. Du Bois). El artículo argumenta que el movimiento por el sufragio femenino fue de hecho un paso gigantesco hacia el ideal estadounidense de igualdad de género, pero no alcanzó la igualdad racial. Hay un legado mixto para abrazar y reevaluar al mismo tiempo; por lo tanto, el Centenario del Sufragio Femenino no debe ni puede ser una celebración de un solo tema de género, ni una sinfonía única para todos, sino una ocasión histórica para un diálogo íntimo y matizado entre género y raza. El artículo sugiere que el Centenario no solo debe celebrar a las sufragistas estadounidenses blancas, sino que debe ser una oportunidad para dar un paso histórico para cruzar la línea de color que ha aislado a las mujeres afroamericanas, así como a las mujeres de color de otras razas, etnias y herencias del centro de poder.

Résumé Le centenaire du suffrage des femmes est arrivé dans un moment culturellement décisif dans les États-Unis, ainsi que à un an des élections présidentielles à haut risque. Tout ceci est aussi accompagné de l’émergence du mouvement «Black Lives Matter» (La vie des noirs compte) à échelle mondial après la mort de l’afro-américain George Floyd sous les genoux des policiers blancs. Dans ces États-Unis d’Amérique où «je ne peux pas» respirer, c’est un nouveau moment d’éveil culturel. ¿Est-ce que le centenaire est un séparateur ou un unificateur des femmes américaines en 2020? Cet article vise à répondre cette question à partir de la révision des amendements 14 et 15 de la Constitution, ainsi que de la pensée des figures iconiques telles que Elizabeth Cady Stanton, Susan B. Anthony, Frederick Douglass, William Edward Burghardt Du Bois et Mary Church Terrell. Sous une approche interdisciplinaire ancrée dans les études historiques et culturelles, l’article analyse la séparation des deux éléments viscéraux pertinents à l’identité culturel (le genre et la race) dans le Mouvement pour le Suffrage des Femmes; cette dite séparation dessine un patron de leur intersection et en même temps trace «une double conscience» (terme emprunté de W.E.B Du Bois). L’article argumente que le mouvement du suffrage des femmes a été, en effet, un pas immense vers l’idéal américain d’égalité de genre mais il n’a pas atteint l’égalité raciale. Alors, il y a un héritage mixte pour embrasser et réévaluer en même temps; c’est pourquoi le centenaire du suffrage des femmes ne doit ni ne peut être une célébration du genre comme un seul sujet, non plus comme une seule symphonie unique pour tous; au contraire, elle est une occasion historique pour un dialogue intime et combiné entre le genre et la race. Finalement, cet article suggère que le Centenaire de doit pas seulement célébrer les Suffragettes américaines blanches, sinon qu’elle doit être une opportunité pour donner un pas historique et traverser la ligne de la couleur qui a isolé aux femmes afro-américaines, ainsi que les femmes de couleur d’autres races, ethnies et les héritages du centre du pouvoir.

Abstract Introduction: Propofol is a widely used anesthetic and its dose is closely related to aging. Telomere length (TL) is a unique heritable trait, and emerging as a biomarker of aging, health and disease. Telomerase RNA component (TERC) plays an important role in maintaining TL. We proposed a hypothesis that propofol dose in general anesthesia can be predicted by measuring TL before operation, which greatly reduced the risk of anesthesia, especially the elderly. Methods: The association between the propofol dose in anesthesia induction and: TL in the DNA of peripheral blood leukocytes; body weight; sex; difference of the Bispectral Index (BIS) before and after anesthesia induction in patients was evaluated by multivariable linear regression analyses. The mutation at the 5’end or 3’end of TERC was detected. We recruited 100 patients of elective surgery. Results: We found that propofol dose in anesthesia induction was clearly correlated significantly with TL (r = 0.78, p < 0.001), body weight (r = 0.84, p = 0.004), sex (r = 0.83, p= 0.84, p = 0.004), sex (r = 0.83, p = 0.004), and difference of BIS before and after anesthesia induction (r = 0.85, p = 0.029). By comparing the absolute values of standardized regression coefficients (0.58, 0.21, 0.19, and 0.12) of the four variables, it can be seen that TL contributes the most to the propofol dose in anesthesia induction. However, the mutation at the 5’ end or 3’ end of TERC was not found. Conclusions: These findings provide preliminary evidence that the propofol dose in anesthesia induction was clearly correlated with genetically determined TL. TL may be a promising predictor of the propofol dose, which is beneficial to improve the safety of anesthesia and reduce perioperative complications.

ABSTRACT In soybeans from different years, the infrared spectroscopy waveforms exhibit similarities, yet variations in aging time lead to significant differences in their fatty acid content. To rapidly discern the year of soybean production, this study employed ten feature extraction algorithms in conjunction with Convolutional Neural Networks (CNN) to establish models for classifying soybeans from different years (2019, 2020, and 2021). The research findings reveal the following: (1) The CNN models, after feature extraction, all demonstrated improved accuracy. Notably, the optimal models for both powdered and granulated states were the Kpca-CNN models, achieving an accuracy of 100%. The corresponding loss function values were 0.0002 and 0.0007, with processing times of 0.19 seconds and 0.20 seconds, respectively. (2) The modeling results of all models suggest that the classification accuracy of soybean powder spectral data is higher compared to soybean particle spectral data. (3) Validation of the optimal Kpca-CNN model confirmed its consistent accuracy of 100% when introducing new data or reducing the size of the training dataset. In conclusion, the fusion of near-infrared spectroscopy analysis and CNN technology is considered an effective method for classifying soybeans from different years. This method provides a practical solution for the rapid and precise determination of seed production years.

ABSTRACT This article addresses the problem of plagiarism in scientific production and highlights its negative impact on the integrity and credibility of academic research. There is a lack of consensus and clarity in the definition and understanding of plagiarism, which makes it difficult to identify and effectively address it. This can generate discrepancies in the way plagiarism is judged and sanctioned, which affects the integrity and credibility of scientific publishing. Furthermore, scientific journals often lack resources and clear guidelines to adequately and consistently address plagiarism. The objectives of the study were: 1) to identify the main perspectives on plagiarism that can be presented in scientific publishing and 2) to establish a guide that allows scientific journals to act against these unethical attitudes. To obtain results, methods were used at the theoretical and empirical levels, fundamentally the classic documentary analysis. The typologies that most affect scientific journals were identified and a guide was established on which publications can rely to minimize this attitude. It was concluded that scientific journals must take a firm and decisive stance when detecting plagiarism in an article. To effectively address plagiarism it is essential to rigorously verify and confirm the allegations, communicate directly with the responsible author, and undertake a thorough investigation to assess the extent of the plagiarism.

RESUMEN El presente artículo aborda el problema del plagio en la producción científica y destaca su impacto negativo en la integridad y credibilidad de la investigación académica. Existe una falta de consenso y claridad en la definición y comprensión del plagio, lo que dificulta su identificación y abordaje efectivo. Esto puede generar discrepancias en la forma en que se juzga y se sanciona el plagio, lo que afecta la integridad y credibilidad de la edición científica. Además, las revistas científicas a menudo carecen de recursos y pautas claras para abordar el plagio de manera adecuada y consistente. Se plantearon como objetivos del estudio: 1) identificar las principales perspectivas sobre plagio que pueden presentarse en la edición científica y 2) establecer una guía que permita a las revistas científicas accionar ante estas actitudes antiéticas. Para la obtención de resultados se emplearon métodos en los niveles teórico y empírico, fundamentalmente el análisis documental clásico. Se identificaron las tipologías que más afectan a las revistas científicas y se estableció una guía en las que las publicaciones pueden apoyarse para minimizar esta actitud. Se concluyó que las revistas científicas deben tomar una postura firme y decidida ante la detección de plagio en un artículo. Para abordar el plagio de manera efectiva es esencial verificar y confirmar de manera rigurosa las acusaciones, comunicarse directamente con el autor responsable y emprender una investigación exhaustiva para evaluar la extensión del plagio.

Abstract Background Research has shown that a fundamental frequency of 40 Hz in continuous neural oscillation is indicative of normal brain activity; in Alzheimer disease (AD) patients, these oscillations either disappear or are significantly interrupted. Research has also indicated that the degenerative impacts of AD in mice were mitigated by the synchronization of 40-Hz acousto-optic stimulation (AOS). Objective To examine the impact of employing a 40-Hz AOS intervention on the induction of a substantial 40-Hz frequency entrainment and improvement in working memory performance among a sample of young individuals in good health. We conduct an analysis of event-related potentials (ERPs) derived from electroencephalogram (EEG) data following the presentation of AOS. Methods We recruited 20 healthy volunteers (median age: 25 years; 8 female subjects). Following the administration of various stimuli, including no stimuli, 40-Hz AOS, pink noise, and 40Hz acoustic stimuli (AS), the participants were required to complete a working memory task. A total of 62 electrodes were used to record EEG data, which was subsequently analyzed to investigate the impact of AOS on the activity of working memory. We also aimed to determine if AOS lead to a more pronounced 40-Hz frequency entrainment. Results Following the administration of AOS, a notable enhancement in the 40-Hz power of pertinent cerebral areas was observed, accompanied by a substantial improvement in the performance of the subjects on working memory tests subsequent to the stimulation. Conclusion The findings unequivocally establish the efficacy of using AOS to enhance the 40-Hz power and working memory.

Resumo Antecedentes A pesquisa mostrou que uma frequência fundamental de 40 Hz em oscilação neural contínua é indicativa de atividade cerebral normal. Em pacientes com doença de Alzheimer (DA), essas oscilações desaparecem ou são significativamente interrompidas. A pesquisa também indicou que os impactos degenerativos da DA em camundongos foram mitigados pela sincronização da estimulação acústico-óptica (EAO) de 40 Hz. Objetivo Examinar o impacto do emprego de uma intervenção EAO de 40 Hz na indução de um arrastamento substancial de frequência de 40 Hz e na melhoria do desempenho da memória de trabalho entre uma amostra de jovens com boa saúde. Conduzimos uma análise de potenciais relacionados a eventos (PREs) derivados de dados de eletroencefalograma (EEG) após a apresentação de EAO. Métodos Recrutamos 20 voluntários saudáveis (idade média: 25 anos; 8 mulheres). Após a administração de vários estímulos, incluindo nenhum estímulo, EAO de 40 Hz, ruído rosa e estímulos acústicos (EA) de 40 Hz, os participantes foram obrigados a completar uma tarefa de memória de trabalho. Um total de 62 eletrodos foram utilizados para registrar dados de EEG, que foram posteriormente analisados. para investigar o impacto do AOS na atividade da memória de trabalho. Também pretendemos determinar se o AOS leva a um arrastamento de frequência de 40 Hz mais pronunciado. Resultados Após a administração de AOS, foi observado um aumento notável na potência de 40 Hz de áreas cerebrais pertinentes, acompanhado por uma melhoria substancial no desempenho dos sujeitos em testes de memória de trabalho subsequentes à estimulação. Conclusão Os resultados estabelecem inequivocamente a eficácia do uso do AOS para melhorar a potência de 40 Hz e a memória de trabalho.

Abstract: En | Text: En | PDF: En

A shift in reservoir stratification and mixing significantly affects the water column ecosystem, which in turn leads to changes in phytoplankton abundance and community structure. To explore the effects of stratification and mixing on the phytoplankton community structure of a diversion reservoir, a 1-year survey was divided into a stratification period in 2020, a mixing period in 2020, and a stratification period in 2021, and redundancy analysis (RDA), variance partitioning analysis (VPA) and Pearson correlation analysis were used to analyse the key drivers affecting the phytoplankton functional groups, using Xikeng Reservoir as a case study. During the study period, 8 phyla, 69 genera and 9 major functional groups were observed in this reservoir. The dominant functional groups varied significantly, being X1 in the stratified period in 2020; P and D in the mixing period in 2020; and D, X1, and M in the stratified period in 2021. The phytoplankton diversity index was greater in the mixing period than in the stratification period, in agreement with the results of the aquatic ecological status evaluation (Q index, higher in the mixing period than in the stratification period). However, phytoplankton diversity of Xikeng Reservoir was of limited value in assessing the degree of water pollution, so should be considered in combination with the Q index. Water temperature (WT), mixing depth (Zmix), nitrogen-phosphorus ratio (N/P), and total nitrogen (TN) were important drivers of phytoplankton functional group dynamics in different periods. The study provides a valuable reference for assessing the relationship between environmental factors and phytoplankton communities, as well as for the evaluation and conservation of aquatic ecosystems in southern China's water diversion reservoirs.
