Diagnosing the controls on desert dust emissions through the Phanerozoic
Authors: Xie Yixuan , Lunt Daniel J. , Valdes Paul J.
Published: March 2024

Abstract. Desert dust is a key component of the climate system, as it influences Earth's radiative balance and biogeochemical cycles. It is also influenced by multiple aspects of the climate system, such as surface winds, vegetation cover, and surface moisture. As such, geological records of dust deposition or dust sources are important paleoclimate indicators; for example, dust records can be used to decipher aridity changes over time. However, there are no comprehensive records of global dust variations on tectonic time scales (10's of millions of years). Furthermore, although some modelling studies have focused on particular time periods of Earth's history, there has also been very little modelling work on these long timescales. In this study, we establish for the first time a continuous model-derived timeseries of global dust emissions over the whole Phanerozoic (the last 540 million years). We develop and tune a new offline dust emission model, DUSTY, driven by the climate model HadCM3L. Our results quantitatively reveal substantial fluctuations in dust emissions over the Phanerozoic, with high emissions in the Late Permian to Early Jurassic (×4 pre-industrial levels), and low emissions in the Devonian-Carboniferous (×0.1 pre-industrial levels). We diagnose the relative contributions from the various factors driving dust emissions and identify that the non-vegetated area plays a dominant role in dust emissions. The mechanisms of paleo hydrological variations, specifically the variations in low-precipitation-induced aridity, which primarily control the non-vegetated area, are then diagnosed. Our results show that paleogeography is the ultimate dominating forcing with the dust emissions variations explained by indices reflecting the land-to-sea distance of tropical and subtropical latitudes, whereas CO2 plays a marginal role. We evaluate our simulations by comparing them with sediment records and find fair agreement. This study contributes a quantified and continuous dust emission reconstruction, as well as an understanding of the mechanisms driving paleohydroclimate and dust changes over Earth's Phanerozoic history.
Assimilating ESA-CCI Land Surface Temperature into the ORCHIDEE Land Surface Model: Insights from a multi-site study across Europe
Authors: Olivera-Guerra Luis-Enrique , Ottlé Catherine , Raoult Nina , Peylin Philippe
Published: March 2024

Abstract. Land surface temperature (LST) plays an essential role in water and energy exchanges between Earth’s surface and atmosphere. Recent advancements in high-quality satellite-derived LST data and land data assimilation systems present a unique opportunity to bridge the gap between global observational data and land surface models (LSMs) to better constrain the water/energy budgets in a changing climate. In this vein, this study focuses on the assimilation of the ESA-CCI LST product into the ORCHIDEE LSM (the continental part of the IPSL Earth System Model) with the aim of optimizing key parameters to improve the simulations of LST and surface energy fluxes. We use the land data assimilation system for the ORCHIDEE model (ORCHIDAS) to conduct a series of synthetic twin data assimilation experiments accounting for real data availability and uncertainty from ESA-CCI LST to find an optimal strategy for assimilating LST. Here, we test different strategies of assimilation, notably investigating: i) two optimization methods (random-search and gradient-based) and ii) different ways to assimilate LST using the only raw data and/or different characteristics of the LST diurnal cycle (e.g. mean daily, daily amplitude, maximum and minimum temperatures, morning and afternoon gradients). Upon identifying the optimal approach, we use it to assimilate ESA-CCI LST data across 34 sites in Europe provided by the WarmWinter database. Our results demonstrate the effectiveness of assimilating 3-hourly CCI-LST data over a single year in 2018, improving the accuracy of simulated LST and fluxes. This improvement, assessed against CCI-LST and in situ observations, reaches up to 60 % reduction in root mean square deviation, with a median reduction of 20 % over the entire validation period (2009–2020). Furthermore, we evaluate the effectiveness of optimized parameters for application at larger scales by using the median of optimized parameters per vegetation type across sites. Notably, the performances for both LST and fluxes exhibit not only consistent stability over the years, comparable to using site-specific parameters, but also indicate a significant improvement in the modeled fluxes. Future works will be focused on refining the utilization of the observation uncertainties provided by the ESA-CCI LST product (e.g. decomposed uncertainties and spatio-temporal variability) in the assimilation process.

Published: March 2024

Abstract. Glacier snouts respond to climate change by forming proglacial meltwater lakes, thereby influencing glacier mass balance and leading to advancements and surges. The positive feedback of climate change results in more frequent ice-dammed glacial lake outburst floods (GLOFs) in the Karakorum and surrounding regions, often facilitated by englacial conduits. However, the complex and multi-factor processes of conduit development are challenging to measure. Determining the lake depths that might trigger GLOFs and the numerical model specifications for breaching are still being determined. Empirical estimates of lake volumes, along with field-based monitoring of lake levels and depths and the assessment of GLOF risks, enable warnings and damage mitigation. Using historical data, remote sensing techniques, high-resolution imagery, cross-correlation feature-tracking, and field-based data, we identified the processes of lake formation, drainage timing, and triggering depth. We developed empirical approaches to determine lake volume and trigger water pressure leading to a GLOF. The correlation of glacier surge and lake volume reveals that glacier surge velocity plays a crucial role in lake formation and controlling the size and volume of the lake. Lake volume estimation involves geometric considerations of the lake basin shape. A GLOF becomes likely when the lake's non-dimensional depth (n’) exceeds 0.60, correlating with a typical water pressure on the dam face of 510 kPa. Additionally, we identified the critical risk zone of lakes, where all lake outburst floods occur, as the point where the lake volume reaches or exceeds 60 % of its capacity. These field-based and empirical findings not only offer valuable insights for early warning procedures in the Karakorum but also suggest that similar approaches can be effectively applied to other mountain environments worldwide where GLOFs pose a hazard.

Abstract. There is considerable academic interest in the potential for air quality improvement as a co-benefit of climate change mitigation. Few studies use regional air quality models for simulating future co-benefits, but many use global chemistry-climate model output. Using regional atmospheric chemistry could provide a better representation of air quality changes than global chemistry-climate models, especially by improving the representation of elevated urban concentrations. We use a detailed regional atmospheric chemistry model (WRF-Chem v 4.2) to model European air quality in 2050 compared to 2014 following three climate change mitigation scenarios. We represent different climate futures by using air pollutant emissions and chemical boundary conditions (from CESM2-WACCM output) for three Shared Socioeconomic Pathways (SSP1-2.6, SSP2-4.5, SSP3-7.0; a high, medium and low mitigation pathway). We find that in 2050, following SSP1-2.6, mean population-weighted PM2.5 concentrations across European countries reduces by 52 % compared to 2014. Whilst under SSP2-4.5, this average reduction is 34 %. The smallest average reduction was 18 % by following SSP3-7.0. Maximum 6-monthly-mean daily-maximum 8 h (6mDM8h) ozone (O3) is reduced across Europe by 15 % following SSP1-2.6, and 3 % following SSP2-4.5, but increases by 13 % following SSP3-7.0. This demonstrates clear co-benefits of climate mitigation. The additional resolution allows us to analyse regional differences and identify key sectors. We find that mitigation of agricultural emissions will be key for attaining meaningful co-benefits of mitigation policies, evidenced by the importance of changes in NO3 aerosol mass to determining future PM2.5 air quality and changes in CH4 emissions to future O3 air quality.

Abstract. Considered as the Asian water tower, the Qinghai–Xizang Plateau (QXP) processes substantial permafrost, where its hydrological environments are spatially differed and can be easily disturbed by changing permafrost and melting ground ice. Permafrost degradation compels melting permafrost to become an important source of surface runoff, changes the storage of groundwater, and greatly influences the hydrological processes in permafrost regions. However, the evidences linking permafrost degradation and hydrological processes on the QXP are lacking, which increase the uncertainties of the evaluation results of changing permafrost on the water resources. Stable isotopes offer valuable information on the connections between changing permafrost (ground ice) and water components. It is therefore particularly important to observe the changes in the stable isotopes of different waterbodies, which can vary over hourly to annual timescales and truly capture the thawing signals and reflect the influence of permafrost (ground ice) on the regional hydrological processes. The Beiluhe Basin (BLH) in the hinterland of QXP were selected, which well integrates all the water components related to hydrological cycles, and is an ideal site to study hydrological effect of permafrost change. This paper presents the temporal data of stable isotopes (δ18O, δD, and d-excess) in different water bodies (precipitation, stream water, thermokarst lake, and groundwater) in the BLH produced between 2017 and 2022. In special, the first detailed stable isotope data of ground ice at 17 boreholes and 2 thaw slumps are presented. A detailed description of the sampling processes, sample pretreating processes, and isotopic data quality control is given. The data firstly described the full seasonal isotope amplitude in the precipitation, stream, and thermokarst lakes, and delineated the depth isotopic variability in ground ice. Totally, 554 precipitation samples, 2402 lakes/ponds samples, 675 stream water samples, 102 supra-permafrost water samples, and 19 sub-permafrost water samples were collected during six years’ continuous sampling work. Importantly, 359 ground ice samples at different depths from 17 boreholes and 2 profiles were collected. This first data set provides a new basis for understanding the hydrological effects of permafrost degradation on the QXP. It also provides supports on the cryospheric study on the Northern Hemisphere.
Unsupervised anomaly detection of permanent magnet offshore wind generators through electrical and electromagnetic measurements

Published: March 2024

Abstract. This paper investigates fault detection in offshore wind permanent magnet synchronous generators (PMSG) for demagnetization and eccentricity faults (both static and dynamic) at various severity levels. The study utilizes a high-speed PMSG model, on the NREL 5-MW reference offshore wind turbine, and at the rated wind speed, to simulate healthy and faulty conditions. An unsupervised convolutional autoencoder (CAE) model, trained on simulated signals from the generator in its healthy state, serves for anomaly detection. The main aim of the paper is to evaluate the possibility of fault detection by means of high-resolution electrical and electromagnetic signals, given that the typically low-resolution standard measurements used in SCADA systems of wind turbines often impede the early detection of incipient failures. Signals analyzed include three-phase currents, induced shaft voltage, electromagnetic torque, and magnetic flux (airgap and stray) from different directions and positions. The performance of CAE models is compared across time and frequency domains. Results show that in the time domain, stator three-phase currents effectively detect faults. In the frequency domain, stray flux measurements, positioned at the top, bottom, and sides of outside the stator housing, demonstrate superior performance in fault detection and sensitivity to fault severity levels. Particularly, radial components of stray flux can successfully distinguish between eccentricity and demagnetization.

Thyroid hormones play an important role in regulating metabolism. A large body of literature suggests an increased risk of developing metabolic syndrome (MS) in individuals with hypothyroidism, but little data exists on the effects of high-normal levels of thyroid-stimulating hormone (TSH) on metabolism.

Material and methods. The study was conducted on a representative sample of people aged 25–44 years (n = 1513, of which 840 were women). The analysis included the results of 343 women. A questionnaire, anthropometric and biochemical study were carried out. Biochemical parameters were analyzed in quartiles of TSH content. Determination of MS was carried out using the criteria of NCEP ATP III (2001), IDF (2005), VNOK (2009).

Results. TSH content in the examined sample was 1.5 [1.0; 2.2] mU/l (median [lower quartile; upper quartile]). Among women 25–44 years old, women with highly normal TSH level (3.1 [2.7, 3.8] mU/l) have less favorable metabolic parameters. MS was detected in 31 % cases, with a predominant increase in the frequency of abdominal obesity – in 51 %, with increased triglyceride levels in 18 %. Women with hypertriglyceridemia had higher TSH content than those with normal triglyceride levels (2.4 ± 1.6 vs. 1.8 ± 1.3 mU/L, respectively, p = 0.007).

Conclusions. In women 25–44 years of age, high-normal TSH content is more often associated with metabolic unhealth.
Mapping the Literature and Future Research Agenda of Employee Engagement: A Bibliometric Analysis of the past 20 years
Authors: Prof. (Dr) Sandhya Mehta Guneet Kaur,
Published: March 2024

Purpose: The aim of this study is to highlight the intricacies involved in the conceptualization and theorization of Employee Engagement in the past twenty years. By analyzing the antecedents and, this study aims to identify the gaps in the present literature so that future research directions can be deliberated.

Design/methodology/approach: This research applies a bibliometric analysis approach in order to synthesize upcoming themes in the area of employee engagement.

Findings: Employee Engagement as a concept has been widely conceptualized and mainly differentiated into two dimensions – psychological or attitudinal and behavioural.  Less research has taken place on the behavioural front of the topic wherein the extra-role performance by engaged employees’ discretionary behaviour should be studied. Also, factors like the nature of work and leadership, and emotional intelligence need attention.

Limitations: The present study has only undertaken articles and has not focused on book chapters, conference proceedings and focused on English language research papers. Also, the study excluded research studies where engagement was examined as a moderator or mediator as the emphasis was on understanding the antecedents of engagement.

Implications: Since engagement levels have dropped in the past decade, it becomes imperative for practitioners to overhaul it’s understanding and make every employee’s experience a unique one by engaging them.

Published: March 2024

Economic threats, along with political identities and ideologies, are associated with affective polarization. However, there is still a need to learn more about the consequences of different economic threats and identities fueling polarization. We take a longitudinal perspective in testing the influence of these phenomena on affective polarization. Specifically, we tested the effect of subjective personal and collective economic threats and political, national, regional, and European identities on affective polarization towards politicians and partisans in Spain. We use four waves of the E-DEM panel study from Spain (N = 2,501) collected between 2018 and 2019. We conducted longitudinal multilevel analyses to determine the growth in affective polarization and included predictors at the between- and within-person levels. Consistent with our hypotheses, we found that collective economic threats, such as perceiving more unfairness in the distribution of wealth and being dissatisfied with the Spanish economy, positively predict affective polarization. Contrary to our expectations, personal economic threats did not predict affective polarization. Furthermore, political and national identities positively predicted affective polarization towards politicians and partisans. Interestingly, exploratory analyses suggested that the associations between economic threats, identities, and affective polarization are moderated by political ideology. We discuss how economic threats and identities may exacerbate animosities toward political actors.

Published: March 2024

Background: Myiasis is a neglected disease, characterized by ill-defined diagnostics and management protocols. Published epidemiological and clinical studies of myiasis are still scarce, although several countries, such as Oman, have reported a few cases over the past 30 years. This study explores the epidemiological profile and clinical characteristics of myiasis in South Batinah Governorate (SBG), Oman.

Methodology: A prospective surveillance study was conducted in SBG from 1st November 2018 to 31st October 2019. Clinical and epidemiological data were collected using a pre-designed reporting form for suspected and confirmed cases.

Results: A total of 188 cases were reported, of which 81.4% were male. One-third of cases were 11–20 years old, and a quarter reported exposure inside house. The rate of exposure was 16 per 10000 in Nakhal and Wadi Mawel. About 57% patients reported multiple re-exposure. Almost 60% of patients developed nasal or oral myiasis, 25% developed myiasis in the eye, and 4% in the ear. The most common respiratory symptoms were cough (83%), runny nose (48%), and foreign body sensation (35%). Over 50% of patients with eye exposures had redness, pain, and itchiness. Most patients (89.3%) kept animals at homes. Many cases occurred between December 2018 and April 2019, with almost one-third of exposures occurring at 5 p.m. Re-exposure likelihood for patients residing in Nakhal and Wadi Mawel was high; OR = 2.49 (95% CI 1.14–5.45), with OR = 3.59 (95% CI 1.37–9.39) for 11–20-year-olds and, OR = 3.01 (95% CI 1.07–8.42) for patients ≥ 31 years.

Conclusion: The myiasis exposure rate is high in certain areas and age groups, which is most likely associated with animal-related activities. The disease has a significant impact upon people’s health in SBG. Therefore, urgent active-surveillance and clinical studies are warranted to explore possible preventive measures and treatment options. Adopting one health approach could offer an effective strategy for preventing myiasis in human and animal populations.

Ultramodern analytical techniques must also be hyphenated with cheaper and less complex techniques such as UV-visible spectrophotometry to confirm the formation of organic synthesis products. Here, the synthesis of 4 compounds (HC4ATIOF, HFEC, HCPA4NO2, and HICNM) from a clinically approved antitubercular drug, the Isoniazid, was preliminarily verified by UV-Vis spectrophotometry. Spectra recorded in the UV-Vis region for the four possible isoniazid derivatives allowed us to confirm the synthesis of just one acylhydrazone from isoniazid, the HICNM, since the absorption bands observed in the UV-Vis spectra of the reactants and the product obtained are completely different, indicating the formation of a new substance.

This study determined the effects of Sesbania grandiflora (SG) leaf extract on the growth, feed utilization efficiency and non-specific immunological responses in black tiger shrimp (Penaeus monodon). Three diets were prepared by mixing the methanol extract of SG onto a pellet feed (34% protein) at concentrations of 0% (control), 0.05% (T1) and 0.1% (T2), respectively. Ten shrimps (mean weight 2.1g), were reared in each tank of 80 L, and the weight and immunological reaction of shrimp were received after a feeding trail of 28 days. The dietary extract treated shrimp had better growth performance (WG, SGR), and feed utilization efficiency (FCR, PER) compared to the control group. The treated shrimp exhibited enhanced immunological responses; the total haemocyte count, prophenoloxidase activity, superoxide dismutase activity, and shorter haemolymph clotting time compared to the control shrimp. In conclusion, a lower level of SG (0.05%) was found to be most effective in terms of immune response enhancement; hence, this plant could be a good source for feed additives for enhancing sustainable shrimp production.

Published: March 2024

Работа посвящена особенностям процесса теплообмена между газом и твердой фазой пористой среды, выявленных при измерении температуры газа с помощью термопары, в процессе горения смеси газов в закрытом сосуде. Проведены измерения температуры газа и пористой среды с помощью тонкой термопары в двух процессах: сжатие газа и охлаждение газа в данной поре после прохождения пламени. Показано, что в процессе сжатия газа с постоянной скоростью термопара позволяет измерить установившуюся температуру газа, при этом запаздывание установившегося значения зависит от диаметра термопары. Показано, что в процессе охлаждения мгновенно нагретого газа результаты измерения температуры газа с помощью термопары будут существенно занижены из-за высокой теплоемкости термопары по сравнению с теплоемкостью газа в поре. Указанные эффекты являются причиной существенных ошибок измерения температуры, а также ошибки в пространственной координате. Показано, что интенсификация процесса охлаждения газа при колебаниях давления является причиной гашения пламени в пористой среде на стадии перехода из свободного пространства в пористую среду, которая происходит на фоне сильных колебаний давления

Published: March 2024

Интерес к гибридным и прямоточным реактивным двигателям требует применения соответствующих высокоэнергетических систем/компонентов. В условиях высокоскоростного обдува стандартные компоненты ракетных топлив имеют относительно низкую скорость газификации. В качестве альтернативы предлагается использовать парафины и композиции на их основе. Парафины – высокоэнергетические углеводороды имеющие низкую температуру плавления ведущую к высокой скорости газификации в условиях высокоскоростного обдува. Приводятся результаты экспериментального исследования скоростных характеристик смесей парафина с различными добавками в условиях интенсивного обдува горячим воздухом при давлении 1 МПа. В качестве 10% добавки использовались стеариновая кислота, наноалюминий "Алекс", гидрид алюминия AlH3, B и механоактивированный борид алюминия AlB2. Исследование проводилось на образцах цилиндрической формы с центральным каналом. С помощью СВЧ датчика оригинальной конструкции в экспериментах измерялась текущий диаметр образца в реальном времени с последующим расчётом линейной скорости газификации. Также проводились измерения параметров газового потока и температурного профиля в к-фазе. На основе полученных данных сформулирована физико-математическая модель газификации парафинового топлива при обдуве горячим воздухом.

O Sistema Único de Saúde é o sistema hegemônico do país, sendo responsável pela atenção à saúde da maioria dos cidadãos brasileiros, abrangendo serviços ambulatoriais especializados, serviços de apoio ao diagnóstico e a terapêutica, serviço pré-hospitalar de urgência e emergência. As políticas públicas de saúde no Brasil são um conjunto de medidas estabelecidas pelo governo para resolver questões relacionadas à saúde e qualidade de vida, visando o bem estar da população. O Estado de Goiás executa as políticas públicas de saúde através da Secretaria de Estado da Saúde de Goiás (SES-GO), sendo que, para se implementar uma rede hospitalar de média e alta complexidade regionalizada, é necessário um eficiente departamento de Projetos de Infraestrutura. O artigo possui o objetivo de estudar o Gerenciamento de Risco na Análise de Projetos da Secretaria de Estado da Saúde de Goiás. A experiência de gerir a área de Projetos de Infraestrutura da Secretaria de Estado da Saúde de Goiás envolve diversas responsabilidades, sendo o primeiro passo a execução do Planejamento para organizar a gestão, com o intuito de Identificar, Analisar e Avaliar os Riscos que poderão se materializar na análise de Projetos de Infraestrutura, através do Project Model Canvas, que é uma metodologia de Planejamento. O próximo passo do Gerenciamento de Riscos, Monitoramento Periódico de Riscos e Ações de Controle, será a avaliação dos resultados positivos, a economia gerada, a efetividade dos controles, probabilidade, impacto e nível de riscos após a implantação da Gestão de Riscos, considerando que a área de Projetos de Infraestrutura é de suma importância para possibilitar a oferta de serviços necessários e imprescindíveis para a população do estado de Goiás.

A laparotomia é um procedimento cirúrgico no qual é feita uma incisão na parede abdominal para ter acesso à cavidade peritoneal. Geralmente, esse procedimento é realizado em situações de emergência, como em casos de trauma abdominal grave ou obstrução intestinal, onde o médico cirurgião pode avaliar os órgãos internos, realizar reparos ou remover tecidos doentes. Contudo, os procedimentos cirúrgicos, especialmente a laparotomia, dada a sua complexidade, podem originar diversas complicações. Assim, complicações como infecções de feridas pós-operatórias, uma consequência comum de muitas cirurgias, podem levar a resultados cirúrgicos desfavoráveis, como hospitalização prolongada e mortalidade. Dessa forma, com o crescente corpo de literatura sobre as complicações cirúrgicas da laparotomia e a sua relação com o prognóstico do paciente, foi possível a realização de uma revisão integrativa de literatura por meio da plataforma PubMed, com seleção e análise criteriosa dos artigos, a fim de revisar e analisar as evidências atuais sobre o impacto da cirurgia por laparotomia no prognóstico do paciente. Nesta revisão foi identificado que a laparotomia em relação a cirurgia laparoscópica, não oferece os benefícios fisiológicos de pequenas incisões, acarreta em mais sangramento e mais danos ao paciente. Desse modo, as principais complicações da laparotomia frente aos demais procedimentos cirúrgicos são: maior perda de sangue, maior tempo de internação hospitalar e recuperação mais lenta. Da mesma forma, a maioria dos estudos sobre este assunto também mostraram que a cirurgia robótica tem as vantagens de fornecer uma perspectiva tridimensional e um posicionamento cirúrgico mais preciso do que a laparotomia. Logo, podemos concluir que a laparotomia é inferior à cirurgia minimamente invasiva (MIS), com mais complicações pós-operatórias gerais. No entanto, a MIS está associada a um maior risco de complicações agregadas intraoperatórias (cistotomia, lesão intestinal e enfisema subcutâneo) e complicações pós-operatórias de fístula. Portanto, os resultados desta revisão facilitam melhorias na avaliação das técnicas cirúrgicas e suas possíveis complicações e prognósticos para o paciente, favorecendo o desenvolvimento e escolha de técnicas aprimoradas de cuidado para pacientes cirúrgicos.

Published: March 2024

A busca por matérias-primas sustentáveis e que apresentam biossegurança e biodegradabilidade são constantes pela ciência, e com isso, para a obtenção dessas características propõe-se o uso de matéria-prima natural, bem como a modificação na estrutura dessas matérias. Sendo assim, apresentamos os polissacarídeos naturais, em especial a goma guar, que com o uso da biotecnologia no intuito de melhorar e potencializar diversas propriedades funcionais, com a técnica da quaternização, podemos direcioná-la como candidata ao tratamento de diversas patologias, inclusive da Doença de Alzheimer. Sendo assim, o objetivo desse trabalho é averiguar o estado da arte e da técnica sobre as aplicabilidades biotecnológicas, bem como também as propriedades farmacológicas da goma guar com ênfase na atividade anticolinesterásica sobre a terapia da doença de Alzheimer utilizando-se palavras-chaves na língua portuguesa e inglesa unidas pelo conector booleano AND nas seguintes bases de dados: LILACS; PubMed; SciELO; Science Direct; Scopus e Web of Science, já para a prospecção tecnológica as bases de patentes consultadas foram WIPO, EPO e INPI (Brasil). A construção do artigo se deu pelo mapeamento da espécie vegetal produtora da goma guar associada as modificações químicas e a doença de Alzheimer. Nos resultados, um aspecto notável e evidenciado, foi a correlação entre o processo de quaternização e a atividade anticolinesterásica dos compostos quaternários abordados nesse estudo. Em outras palavras, conclui-se que a síntese dessas substâncias contendo nitrogênio quaternário e catiônico demonstraram uma atividade anticolinesterásica mais potente. A pesquisa em questão, ainda evidenciou que a goma guar e a goma guar modificada por algum processo químico não apresentam, nas bases de dados pesquisadas, nenhum estudo científico ou patente relacionada a atividade anticolinesterásica.

Authors: Wang Zhiwei , Wang Min
Published: March 2024

In order to address the issue of small objects being difficult to detect effectively in intelligent surveillance videos, this study proposes an improved scheme for the YOLOv7-tiny algorithm. This scheme integrates the Convolutional Block Attention Module (CBAM) into YOLOv7-tiny, effectively enhancing the model's feature extraction and small object detection capabilities in complex backgrounds, thereby improving the overall detection precision. Experimental evaluations indicate that the improved algorithm shows enhanced performance in specific small object detection tasks, achieving an accuracy of 85.6%, a recall rate of 85.2%, and a mean average precision (mAP) of 90.2%. These results demonstrate the effectiveness and practical value of the improved scheme in enhancing the performance of YOLOv7-tiny in small object detection tasks.

Authors: Li Ruixin , Pu Hongping
Published: March 2024

In this paper, an advanced ADS-B trajectory filtering method combining Variable Structure Interactive Multi-Modeling (VSIMM) and Reduced Square Root Volume Kalman Filter (RSRCKF) is proposed. After deeply analyzing the operational characteristics of ADS-B system and the application requirements in the field of aviation, this paper aims to improve the accuracy of ADS-B trajectory tracking by this novel filtering method. In order to cope with the tracking performance problems that may be caused by the model set selection in the traditional interacting multi-model algorithm, the Variable Structure Interacting Multi-Model (VSIMM-RSRCKF) algorithm based on the Simplified Square Root Volume Kalman Filtering is adopted in this study for trajectory filtering. By constructing a comprehensive VSIMM model set to describe the dynamic system of maneuvering targets, the filtering method in this paper simplifies the computational process and reduces the computational complexity by squaring the covariance matrix in the iteration, and at the same time ensures the non-negative qualitative nature of the covariance matrix, which effectively avoids the divergence problem that may occur in the filtering process. The goal of this research is to significantly improve the positioning accuracy and reliability of aircraft using the ADS-B system.

Published: March 2024

In recent years, Sigma-Pi-Sigma neural network (SPSNN) as a special kind of higher-order neural network has attracted wide attention for its fast convergence speed and good approximation ability. However, an inappropriate number of hidden layer neurons may also lead to model underfitting or overfitting, which affects the performance and generalization ability of the model. Therefore, we propose a Sigma-Pi-Sigma neural network with graph regularity by adding a graph regularity term to the network. The results show that the proposed algorithm performs well in terms of training accuracy, testing accuracy and efficiency.
