Визначення структурно-функціональних компонентів механізму формування фінансово-економічних результатів діяльності сільськогосподарських підприємств
Authors: Лизак Михайло
Published: March 2023

Метою дослідження є визначення структурно-функціональних компонентів механізму формування фінансово-економічних результатів діяльності сільськогосподарських підприємств. Дана тема є актуальною, оскільки агарний сектор економіки України формує основну масу валютної виручки для країни, яка впливає на валютний курс і, відповідно, на купівельну спроможність громадян. А правильне визначення структурно-функціональних компонентів механізму формування фінансово-економічних результатів діяльності сільськогосподарських підприємств неодмінно призведе до поліпшення цих результатів. У роботі використано такі методи: систематизації та узагальнення – під час дослідження теоретичних поглядів науковців щодо поняття «механізм», абстрактно-логічний метод – для визначення структурно-функціональних компонентів механізму формування фінансово-економічних результатів діяльності сільськогосподарських підприємств. Проаналізовано теоретичні засади механізму формування фінансово-економічних результатів діяльності сільськогосподарських підприємств. Виявлено, що поняття «механізм» має складну ієрархічну будову й є сукупністю низки компонентів. З’ясовано, що механізм формування фінансово-економічних результатів діяльності сільськогосподарських підприємств можна позиціонувати через призму концептуальних засад, що складаються з таких структурно-функціональних компонентів, як інституційно-регламентний базис, організаційно-управлінська підсистема, аналітично-моніторинговий апарат та виробничо-технологічний блок. Установлено, що механізм формування фінансово-економічних результатів діяльності сільськогосподарського підприємства є невід’ємним структурним елементом налагодження його ефективних виробничо-господарських бізнес-процесів, який у системній взаємодії з іншими управлінськими сегментами підприємства (система менеджменту, кадрове забезпечення, маркетингова політика, збутова діяльність тощо) визначає динамічні параметри конкурентоспроможності підприємства та перспективи його розвитку на аграрному ринку.

Review of Path Selection Algorithms with Link Quality and Critical Switch Aware for Heterogeneous Traffic in SDN
Authors: Nura Yusuf Muhammad , bin Abu Bakar Kamalrulnizam , Isyaku Babangida , Lukuman Saheed Ajibade
Published: March 2023

Software Defined Networking (SDN) introduced network management flexibility that eludes traditional network architecture. Nevertheless, the pervasive demand for various cloud computing services with different levels of Quality of Service requirements in our contemporary world made network service provisioning challenging. One of these challenges is path selection (PS) for routing heterogeneous traffic with end-to-end quality of service support specific to each traffic class. The challenge had gotten the research community's attention to the extent that many PSAs were proposed. However, a gap still exists that calls for further study. This paper reviews the existing PSA and the Baseline Shortest Path Algorithms (BSPA) upon which many relevant PSA(s) are built to help identify these gaps. The paper categorizes the PSAs into four, based on their path selection criteria, (1) PSAs that use static or dynamic link quality to guide PSD, (2) PSAs that consider the criticality of switch in terms of an update operation, FlowTable limitation or port capacity to guide PSD, (3) PSAs that consider flow variabilities to guide PSD and (4) The PSAs that use ML optimization in their PSD. We then reviewed and compared the techniques' design in each category against the identified SDN PSA design objectives, solution approach, BSPA, and validation approaches. Finally, the paper recommends directions for further research.

Published: March 2023

The recent technological advances related to embedded systems, and the increased requirements of the Electric Vehicle (EV) industry, lead to the evolution of design and validation methodologies applied to complex systems, in order to design a product that respects the requirements defined according to its performance, safety, and reliability. This research paper presents a design and validation methodology, based on a hardware-in-the-loop (HIL) approach, including a software platform represented by Matlab/ Simulink and a real-time STM32 microcontroller used as a hardware platform. The objective of this work is to evaluate and validate an Energy Management System (EMS) based on Fuzzy Logic Controller (FLC), developed in C code and embedded on an STM32 microcontroller. The developed EMS is designed to control, in real-time, the energy flow in a hybrid energy storage system (HESS), designed in an active topology, made of a Li-ion battery and Super-Capacitors (SC). The proposed HESS model was organized using the Energetic Macroscopic Representation (EMR) and constructed on Matlab/Simulink software platform. The evaluation and validation of the developed algorithm were performed by comparing the HIL and simulation results under the New European Driving Cycle (NEDC).

Analysis of Russia’s Military Aggression against the Azerbaijan Democratic Republic from the International Legal Perspective
Authors: Rehimli Sefter
Published: March 2023

Background: The article analyses the aggression of Soviet Russia against the Azerbaijan Democratic Republic (ADR) from two perspectives – from the point of view of both Soviet Russia and international law. The problem of whether or not to continue the subject of international law and recognition during the restoration of independence of the states subjected to aggression has created the need for an unambiguous legal response.
Even though the rules of the Montevideo Convention (1933) were fully valid in the establishment of the ADR and the republic became a subject of international law, it was recognised by the Versailles legal system, and it was provided with all the attributes of a state in political, economic, social, and other regards, but it was subject to the aggression of Soviet Russia. The conclusion that it is impossible to assess the aggression of Russia against independent states in the framework of the legal system at the beginning of the 20th century is also controversial. The conclusion that Russia’s military aggression against independent states ‘cannot be evaluated within the framework of the legal system of the period’ is wrong, at least in terms of the IV Hague Convention on the Law and Customs of War on Land Territory of 1907(Regulations (Addendum)) Art. 42, the principle of ‘no transfer of sovereignty to the occupying state during occupation’.
Methods: The occupation of the Republic of Azerbaijan after the restoration of state independence is comparatively analysed using historical and legal methods, taking into account the practice of other states that were attacked by Soviet Russia. A case study approach was used in this article. Since the case study is explanatory and descriptive in design, the description of the conventions on Russian military aggression (1899-1907 Hague Conventions, 1949 Geneva Convention) and practical explanation are included in the article.
Results and Conclusions: The activity of the emigration government, the national liberation struggle, international crimes committed against the population, and the results of the illegal annexation are evaluated according to international law due to the military aggression of Soviet Russia against the ADR. Illegal annexation does not mean the loss of international legal subjectivity of the occupied state. Only in cases of disintegration of the population and disintegration of the society does the loss of state identity occur. Regardless of the existence or effectiveness of the government-in-exile, the long-term struggle of the Azerbaijani people for self-determination during the Soviet era creates an objective basis for the continuity of the ADR.
Exploring the role of microbial interactions in soil and rhizosphere and their effects on litter decomposition, mycorrhizal associations, and plant growth
Authors:   , Zhang Changfeng
Published: March 2023

Millions of microorganisms inhabit the soil, and some of them contribute to the growth of plants. To gain a better understanding of how microbes promote plant growth, we compared the impact of fungal and bacterial communities on litter decomposition and plant growth. Our study revealed that fungi are the primary decomposers of plant litter and have a more significant impact on nutrient cycling than bacteria. Furthermore, when the fungal and bacterial communities are working together, they have a complementary effect on plant growth that is greater than when either community is working alone. Arbuscular mycorrhizal fungi (AMF) are recognized as one of the most important types of plant symbiotic fungi. AMF are widely distributed in the soil and colonize plant roots. They can functionally extend the plant root system and reach areas in the soil beyond the plant roots, enabling plants to access more water and nutrients. We investigated the microbial community that surrounds the AMF hyphae and discovered that fungal hyphae are colonized by specific bacteria and protists. We demonstrate that the microbes that colonize the fungal hyphae play a crucial role in facilitating mycorrhizal development and assisting plant nutrient uptake. We showed that a particular bacterium of the genus Devosia is associated with AMF hyphae, interacts synergistically with the mycorrhiza and promotes plant growth by facilitating nitrogen uptake. This thesis deepens our understanding of the interactions between different microbial groups and their roles in litter decomposition and mycorrhization processes. A better understanding of plant-microbe interactions is essential for the development of effective application strategies for plant-growth-promoting microbes in agriculture. Ultimately microbes can help create sustainable agricultural practices that rely less on chemical inputs for food production.

O Legato na Flauta
Authors: Teixeira Helder
Published: March 2023

A questão fundamental da investigação que ora se apresenta se concentra em aspectos ligados à acústica e a fatores sonoros com caracterí­sticas perceptivas notáveis; fenômenos e eventos que ocorrem num muito breve espaço de tempo nos perí­odos transitórios do som da flauta. A preocupação com tais eventos está intimamente relacionada ao aspecto perceptivo que os mesmos imprimem à execução musical. O propósito focal do artigo se direciona ao legato, uma das principais ferramentas de expressividade do flautista. A importância do legato está associada à boa expressividade e ao fluxo melódico que dá sentido à frase musical. Por esta razão o estudo se concentra em análises de diversas formas de legato, tanto na flauta quanto em outros instrumentos, com utilização de programas de análises de áudio a fim de se conhecer diferentes formas de se obter sons ligados e identificar fenômenos acústicos presentes em meio ao movimento sonoro transitório dos intervalos e como tais fenômenos interferem na sensação de fluxo sonoro. Elaborado à partir da pesquisa desenvolvida na Universidade Federal da Bahia sob o tí­tulo "Aticulus Temporis: estudo dos regimes transitórios do legato na flauta" , este artigo condensa as principais etapas desta pesquisa e suas conclusões.

Más allá de la calificación. Usos de los resultados en evaluaciones de solfeo
Authors: Borne Leonardo da Silveira
Published: March 2023

El presente trabajo, adscrito al campo de la evaluación educacional y del solfeo, es un estudio multicaso de carácter descriptivo e interpretativo en tres Instituciones de Educación Superior brasileñas, y busca responder a la pregunta ¿qué usos se hacen de los resultados de la evaluación del solfeo, después de recabadas las evidencias? Los datos fueron obtenidos a través de entrevistas semi-estructuradas con maestros y estudiantes, observaciones de clase y recopilación de documentos oficiales, y organizados a partir de las tendencias y particularidades. Los resultados, que son parte de un rompecabezas más amplio, muestran que básicamente hay tres posibilidades de usos: la calificación, la retroalimentación de la enseñanza, y la retroalimentación del aprendizaje (formalmente o no). También se discuten las regulaciones realizadas, que pueden ser de naturaleza verbal, musical y/o actitudinal, realizadas en sentido de rechazar/cambiar o corroborar una acción musical de los estudiantes.
La obra pianí­stica de Isaac Albéniz – Una bifurcación estética en sus composiciones de madurez
Authors: Sánchez Alfonso Pérez
Published: March 2023

Dentro de la obra pianí­stica de madurez de Isaac Albéniz se pueden distinguir dos vertientes estéticas, derivadas de la forma en que el compositor concibe cada pieza lo que, a su vez, ha ocasionado una reacción en los intérpretes, crí­ticos y musicólogos. La primera lí­nea explota al máximo los elementos simbólicos musicales de una manera extrovertida y cuasi-programática (Triana, El Corpus Christi en Sevilla, El Puerto y Navarra). La segunda, está representada por fragmentos donde Albéniz hace una búsqueda introspectiva de nuevos caminos en cuanto a melodí­a, armoní­a y forma (La Vega, Jerez y Azulejos). Ambas lí­neas han tenido un grado diferente de aceptación entre los pianistas, lo que a su vez ha producido una muestra heterogénea de grabaciones. Tomando en cuenta la dificultad estética en contraposición al virtuosismo y el grado de transfiguración musical del sentir español, se expone la existencia de dos lí­neas estéticas complementarias dentro de su gramática pianí­stica.
O Gloria de Nepomuceno e o modelo formal cecilianista
Authors: Teixeira Thiago Plaça
Published: March 2023

O presente artigo visa analisar o contexto estético, o estilo e as relações de intertextualidade musical do Gloria da Missa a duas vozes de Alberto Nepomuceno (1864-1920). Verifica-se que a estruturação utilizada pelo compositor no que tange ao plano harmônico, à textura musical, às relações temáticas e aos andamentos, reproduz um específico modelo formal convencional do repertório sacro elaborado no contexto do movimento cecilianista em geral, e particularmente a forma musical encontrada no Gloria da Missa Te Deum laudamus de Lorenzo Perosi (1872-1956).

Uma "ilusão permanente" : a composição de Kathinkas Gesang para flauta e música eletrônica, Karlheinz Stockhausen
Authors: Miranda Paulo Agenor
Published: March 2023

Em residência no IRCAM entre 1983-84, Stockhausen trabalhou na versão de Kathinkas Gesang para flauta e música eletrônica. Interessado na programação do synthétiseur 4X, o compositor vislumbrou "uma nova orientação da lógica musical no campo dos harmônicos" , i.e., controlar deslocamentos de fase de até 212 parciais sob intrincadas relações espectrais. Este artigo analisa a escritura da música eletrônica de Kathinkas Gesang, investigando os procedimentos técnico-composicionais subjacentes à sua realização em estúdio, tal como a concepção dos materiais e dos esquemas de espacialização. Percorrendo um traço de sua poética, a Klangkomposition, delineia-se o minucioso trabalho do compositor sobre o timbre através de sua visão prospectiva frente às relações de fase entre parciais. A despeito das novas possibilidades oferecidas pelo 4X, os árduos procedimentos analógicos e a intensa programação fizeram dessa interface uma "ilusão permanente" para Stockhausen.
O processo de elaboração de uma concepção interpretativa de Tetragrammaton XIII, de Roberto Victorio – Aguçamento da escuta em interação com a análise de gravações da obra
Authors: Rosa Renato Mendes , Barreiro Daniel Luís
Published: March 2023

Neste artigo discutimos o processo de elaboração de uma concepção interpretativa da obra para violão solo Tetragrammaton XIII (2009), de Roberto Victorio, por meio de reflexões suscitadas por análises de gravações da obra. Essas análises, realizadas com o software Sonic Visualiser, com base em gravações feitas pelo primeiro autor (ROSA, 2013a; 2013b), permitiram a visualização de dados sobre os fluxos de andamentos e de dinâmicas das gravações, proporcionando um aguçamento da escuta voltado às nuances interpretativas. O texto apresenta considerações sobre a estrutura da obra e exemplos de trechos analisados, enfatizando elementos interpretativos como o direcionamento gestual e o agrupamento de notas para a formação de gestos. Evidencia-se a contribuição recí­proca entre o estudo interpretativo e analí­tico – realizado com base tanto na partitura como nas gravações – e a articulação desse processo com foco no aguçamento da escuta.
“Pr'um Samba”: reflexões e criações sobre o arranjo no gênero musical brasileiro
Authors: Tiné Paulo José de Siqueira
Published: March 2023

O trabalho discorre sobre resultados parciais obtidos nos recentes projetos de pesquisa sobre a performance de processos criativos em música popular. Esses projetos tiveram como objetivo registrar e promover uma reflexão crí­tica sobre a criação e circulação de uma produção para uma formação idealizada (Ensemble Brasileiro), dentro de uma relação tensional com seus antecedentes históricos (Orquestras Tí­picas, Jazz e Big Bands) próximos. Para tanto elege três etapas inter-relacionadas: interpretação de um arranjo histórico, criação de um novo arranjo e criação de uma composição musical no mesmo gênero. Além disso, para além do processo de produção, o artigo tece breves considerações sobre o contexto histórico que deu origem às discussões levantadas.
PROCESSOS CRIATIVOS, INACABAMENTO E FANTASIA NO FILME "O SOL DO MARMELEIRO"
Authors: Baptista Mónica Santana
Published: March 2023

Partindo do filme "O Sol do Marmeleiro" , pretende-se problematizar os processos criativos de trabalho do artista, nomeadamente as dificuldades que o artista enfrenta relativamente ao inacabamento da obra, sua relação com o objecto representado e ainda à projecção das suas fantasias nessa obra. O filme de Victor Erice servir-nos-á ainda para aprofundar a questão da materialização do tempo em cinema e em pintura, de que forma essa fixação é sempre em última análise fugidia. Os processos criativos do filme - que passam pela tentativa do pintor Antonio Lopez representar a luz de um marmeleiro e da consequente tentativa de o realizador registar essa tentativa de representação - serão analisados para um aprofundamento da relação entre artista, sonho e infância, bem como as noções de autoria, autobiografia e do fazer arte. Teremos em consideração os estudos que nos pareceram relevantes de autores como Bakhtin, Blanchot, Maria Mendes, Didi-Huberman e Merleau-Ponty, buscando exemplos comparativo de outros artistas como Marcel Proust, Virginia Woolf e Rilke, que visam tornar a nossa análise transversal a todas as formas de arte.
TECENDO MEMÓRIAS, ATRAINDO OLHARES: a apropriação de padrões ornamentais e decorativos na expressão artí­stica
Authors: Vaz Rita Isabel , Panek Bernadette Maria
Published: March 2023

Esta pesquisa teve por objetivo investigar a ressignificação de objetos do universo feminino na poética das artistas Beatriz Milhazes e Leda Catunda, do Brasil e Joana Vasconcelos, de Portugal, que utilizam referências e técnicas trazidas de um processo artesanal para a produção de arte. A escolha destas artistas pautou-se na existência da possibilidade de um diálogo entre a poética de cada uma delas com a minha. Em seus trabalhos utilizam-se de objetos femininos, deslocando-os do lugar comum para a arte. Suas cores são vibrantes, tratam de questões sociais e de gênero, inspiram-se na cultura popular. Os trabalhos manuais, os adornos e ornamentos nas obras destas artistas reafirmam o fazer artesanal e feminino no espaço da arte. O objetivo de compreender a poética de cada uma das artistas e a minha própria foi se construindo ao longo do trabalho, na realização de obras autorais. O procedimento metodológico parte da investigação teórica e do trabalho prático em relação dialética ao longo de todo o processo. Algumas perspectivas foram abertas por meio dessa pesquisa que certamente se ampliam na relação com a arte. Ao tecer essa narrativa, ao dialogar com as sensibilidades que as artistas mencionadas evocam nas urdiduras de suas obras, ao ver-me enredada nos possí­veis significados de seus trabalhos identifico minha poética e construo obras que modificam meu próprio olhar, almejando seduzir/transformar o olhar do espectador. Resultou deste processo a realização de cinco obras nas quais utilizei tecidos de padronagens diversas, deslocados de seu uso habitual para construção de objetos, estes trabalhos estabelecem diálogo poético com as artistas mencionadas, remetem à ideia de tecer uma obra ao mesmo tempo em que se tece a vida, contando uma história, deixando "pegadas". A pesquisa teórica ressaltou a importância histórica dos trabalhos manuais, enquanto meio de sobrevivência para muitas mulheres, embora confinadas no espaço doméstico, provocaram a transformação das relações de subordinação financeira. Ao aprofundar-me no estudo da poética destas artistas vislumbro alegria, aconchego, maciez, conforto, cores e formas. Interessa-me especialmente o que elas trazem de intrigante, de belo, de lúdico e, ao mesmo tempo, de contestador.
A Imagem e os Processos de Constituição do Olhar: Interfaces entre Arte, Filosofia e Psicanálise
Authors: Santos Dayanna
Published: March 2023

Este texto pretende refletir sobre a questão da imagem com o campo da arte, da filosofia e da psicanálise, levando em consideração a realidade pós-moderna. Para tanto, buscou-se, num primeiro momento, agregar elementos teórico-conceituais acerca do conceito de imagem desde o pensamento grego. As reflexões propostas, norteadas pelos pressupostos teóricos de Merleau Ponty e Didi-Huberman, versam sobre a produção de signos, sentidos e significados a respeito dos processos de constituição do olhar e de suas relações. A interlocução com a psicanálise lacaniana é necessária para se pensar o sujeito e o inconsciente engendrados em sua não-representatividade e implicados na e pela linguagem. Considera-se, pois, que postos para além da ordem, a concepção de inconsciente e suas manifestações adquirem sentido naquilo que escapa e falha ao sujeito.
A retrospective analysis of phosphatase catalytic subunit gene variants in patients with rare disorders identifies novel candidate neurodevelopmental disease genes
Authors: Lyulcheva-Bennett Ekaterina , Genomics England Research Consortium  , Bennett Daimark
Published: March 2023

Rare genetic disorders represent some of the most severe and life-limiting conditions that constitute a considerable burden on global healthcare systems and societies. Most individuals affected by rare disorders remain undiagnosed, highlighting the unmet need for improved disease gene discovery and novel variant interpretation. Aberrant (de) phosphorylation can have profound pathological consequences underpinning many disease processes. Numerous phosphatases and associated proteins have been identified as disease genes, with many more likely to have gone undiscovered thus far. To begin to address these issues, we have performed a systematic survey of de novo variants amongst 189 genes encoding phosphatase catalytic subunits found in rare disease patients recruited to the 100,000 Genomes Project (100 kGP), the largest national sequencing project of its kind in the United Kingdom. We found that 49% of phosphatases were found to carry de novo mutation(s) in this cohort. Only 25% of these phosphatases have been previously linked to genetic disorders. A gene-to-patient approach matching variants to phenotypic data identified 9 novel candidate rare-disease genes: PTPRD, PTPRG, PTPRT, PTPRU, PTPRZ1, MTMR3, GAK, TPTE2, PTPN18. As the number of patients undergoing whole genome sequencing increases and information sharing improves, we anticipate that reiterative analysis of genomic and phenotypic data will continue to identify candidate phosphatase disease genes for functional validation. This is the first step towards delineating the aetiology of rare genetic disorders associated with altered phosphatase function, leading to new biological insights and improved clinical outcomes for the affected individuals and their families.
Facile preparation of conductive carbon-based membranes on dielectric substrates
Authors: Liu Guoran , Xu Guanchen
Published: March 2023

Graphene has attracted much research attention due to its outstanding chemical and physical properties, such as its excellent electronic conductivity, making it as a useful carbon material for a variety of application fields of photoelectric functional devices. Herein, a new method for synthesizing conductive carbon membranes on dielectric substrates via a low-temperature thermodynamic driven process is developed. Although the obtained films exhibit low crystallinity, their electrical, wetting, and optical properties are acceptable in practice, which opens up a new avenue for the growth of carbon membranes and may facilitate the applications of transparent electrodes as potential plasma-free surface-enhanced Raman scattering (SERS) substrates.
Anti-phosphatidylserine antibody levels are low in multigravid pregnant women in a malaria-endemic area in Nigeria, and do not correlate with anti-VAR2CSA antibodies

Published: March 2023

Anemia is a common malaria-associated complication in pregnant women in endemic regions. Phosphatidylserine (PS) is exposed to the immune system during the massive destruction of red blood cells (RBCs) that accompany malaria, and antibodies against PS have been linked to anemia through destruction of uninfected RBCs. We determined levels of anti-PS IgG antibodies in pregnant women in Ibadan, Nigeria and correlated them to parameters of importance in development of anemia and immunity. Anti-PS correlated inversely with Packed Cell Volume (PCV), indicating that the antibodies could contribute to anemia. There was no correlation with anti-VAR2CSA IgG, haptoglobin or parasitemia, indicating that the modulation of anti-PS response is multifactorial in nature. Anti-PS levels were lowest in multigravidae compared to both primigravidae and secundigravidae and correlated inversely with age. In conclusion, lower levels of anti-PS in multigravidae could be beneficial in avoiding anemia.

Phosphorus (P) is an essential element for the metabolism, growth, and development of living organisms, and it often limits primary production in freshwater ecosystems. During flood events, rivers can transport considerable amounts of particulate organic P (org-P) and inorganic P from the basin to the ocean. Understanding the transport mechanisms and changes in P distribution from upstream to downstream areas of rivers is crucial to estimate its flux to the ocean. However, the processes involved in P transformation and cycling among different forms in rivers are not well understood. To better understand P transformation and total P (TP) concentrations in river basins, this study examined various P forms in bottom sediments, river bank sediments, parent rock material, and soil samples along the Tone River, Japan. P forms such as org-P, Ca-bound phosphorus (apatite, Ca-P), P bound with iron oxides/hydroxides (Fe-P), bio unavailable non-apatite inorganic P (NAIP), and TP were analyzed. The results showed an increase in TP concentration in bottom and bank sediment samples along the course of the Tone River. This change in TP was mostly due to the increases in Fe-P and bioavailable org-P, while Ca-P and NAIP decreased toward the downstream area. Analysis of parent rock in three main mountain group areas (Mount Tanigawa, Mount Akagi, and Mount Tsukuba) showed their downstream impacts on TP and the distribution of P forms. Sediment grain size distribution analysis suggested that Fe-P and org-P fractions increased with decreasing sediment particle size, while Ca-P and NAIP were relatively evenly distributed among all grain sizes. The data revealed the transformation of P forms in sediments of the largest river in the Kanto region, Japan, which influence its flux to the Pacific Ocean. The results suggest that Fe-P and org-P may play a more significant role in P transport from river basins to the ocean than previously thought. The findings of this study can be useful for estimating P fluxes to the ocean and for the management of freshwater ecosystems.

Background

Kidney disease is related to visceral obesity. As a new indicator of obesity, body roundness index (BRI) has not been fully revealed with kidney disease. This study’s objective is to assess the relationship between estimated glomerular filtration rate (eGFR) and BRI among the Chinese population.

Methods

This study enrolled 36,784 members over the age of 40, they were from 7 centers in China by using a random sampling method. BRI was computed using height and waist circumference, eGFR ≤ 90 mL/min/1.73 m2 was considered to indicate low eGFR. To lessen bias, propensity score matching was employed, multiple logistic regression models were utilized to examine the connection between low eGFR and BRI.

Results

The age, diabetes and coronary heart disease rates, fasting blood glucose, and triglycerides were all greater in participants with low eGFR. The BRI quartile was still positively connected with low eGFR after controlling for confounding variables, according to multivariate logistic regression analysis. (OR [95%CI] Q2:1.052 [1.021-1.091], OR [95%CI] Q3:1.189 [1.062-1.284], OR [95%CI] Q4:1.283 [1.181-1.394], P trend < 0.001). Stratified research revealed that the elders, women, habitual smokers, and those with a history of diabetes or hypertension experienced the connection between BRI level and low eGFR. According to ROC, BRI was able to detect low eGFR more accurately.

Conclusion

Low eGFR in the Chinese community is positively connected with BRI, which has the potential to be used as an effective indicator for screening kidney disease to identify high-risk groups and take appropriate measures to prevent subsequent complications.
Ultra-short-term PV power prediction using optimal ELM and improved variational mode decomposition
Authors: Wang Qiang , Lin Hekai
Published: March 2023

The development of photovoltaic (PV) power forecast technology that is accurate is of utmost importance for ensuring the reliability and cost-effective functioning of the power system. However, meteorological factors make solar energy have strong intermittent and random fluctuation characteristics, which brings challenges to photovoltaic power prediction. This work proposes, a new ultra-short-term PV power prediction technology using an improved sparrow search algorithm (ISSA) to optimize the key parameters of variational mode decomposition (VMD) and extreme learning machine (ELM). ISSA’s global search capability is enhanced by levy flight and logical chaotic mapping to search the optimal number of decomposition and penalty factor of VMD, and VMD adaptively decomposes PV power into sub-sequences with different center frequencies. Then ISSA is used to optimize the initial weight and threshold of ELM to improve the prediction performance of ELM, the optimized ELM predicts each subsequence and reconstructs the prediction results of each component to obtain the final result. Furthermore, isolated forest (IF) and Spearman correlation coefficient (SCC) are respectively used in the data preprocessing stage to eliminate outliers in the original data and determine appropriate input features. The prediction results using the actual data of solar power plants show that the proposed model can effectively mine the key information in the historical data to make more accurate predictions, and has good robustness to various weather conditions.

Threatened animal taxa are often absent from most of their original habitats, meaning their ecological niche cannot be fully captured by contemporary data alone. Although DNA metabarcoding of scats and coprolites (palaeofaeces) can identify the past and present species interactions of their depositors, the usefulness of coprolites in conservation biology is untested as few endangered taxa have known coprolite records. Here, we perform multilocus metabarcoding sequencing and palynological analysis of dietary plants of >100 coprolites (estimated to date from c. 400–1900 A.D.) and > 100 frozen scats (dating c. 1950 A.D. to present) of the critically endangered, flightless, herbivorous kākāpō (Strigops habroptilus), a species that disappeared from its natural range in Aotearoa-New Zealand (NZ) after the 13th C. A.D. We identify 24 orders, 56 families and 67 native plant genera unrecorded in modern kākāpō diets (increases of 69, 108 and 75% respectively). We found that southern beeches (Nothofagaceae), which are important canopy-forming trees and not an important kākāpō food today, dominated kākāpō diets in upland (c. >900 m elevation) habitats. We also found that kākāpō frequently consumed hemiparasitic mistletoes (Loranthaceae) and the holoparasitic wood rose (Dactylanthus taylorii), taxa which are nutrient rich, and now threatened by mammalian herbivory and a paucity of dispersers and pollinators. No single dataset or gene identified all taxa in our dataset, demonstrating the value of multiproxy or multigene datasets in studies of animal diets. Our results highlight how contemporary data may considerably underestimate the full dietary breadth of threatened species and demonstrate the potential value of coprolite analysis in conservation biology.

Published: March 2023

Introduction

As the global climate crisis worsens, carbon neutrality has attracted the attention of various nations.

Methods

Based on panel data from 282 Chinese prefecture-level cities from 2008 to 2019, this research considers the execution of the artificial intelligence strategy as a quasi-natural experiment. It uses the difference-in-differences (DID) model to evaluate the effect of artificial intelligence construction on carbon emission reduction.

Results

The findings indicate that implementing the artificial intelligence strategy into practice can lower carbon emissions and advance carbon neutrality, and this conclusion still passes after various robustness tests. The mediating effects reveal that developing green technologies and upgrading the industrial structure are crucial mechanisms for achieving carbon neutrality. The implementation effect varies with time, geographical location, natural resource endowment, and city level.

Discussion

This article examines the influence of artificial intelligence on urban carbon neutrality at the city level, adding to the notion of urban carbon neutrality and providing research support for urban development transformation.
Physiological impacts of beech leaf disease across a gradient of symptom severity among understory American beech
Authors: McIntire Cameron D.
Published: March 2023

Beech leaf disease (BLD) damage is associated with the parasitic nematode Litylenchus crenatae ssp. mccannii. Foliar symptoms manifest as darkened or chlorotic galls in the interveinal portions in the leaf, which become leathery and crinkled under high severity of infection. Though nearly a decade has passed since the discovery of this disease, little is known regarding the impact of BLD on leaf function and physiology. This study assesses the variation in leaf gas exchange and physiological leaf traits among asymptomatic and BLD-infected leaves across a gradient of symptom severity within a natural forested stand in central Connecticut, USA. Leaves with BLD symptoms are found to have significantly reduced carbon assimilation and instantaneous water use efficiency, with increased levels of stomatal conductance as symptom severity progresses. Leaf response to light manipulation is also affected, with an increase in dark respiration and the light compensation point among banded and crinkled leaves. Additionally, BLD symptoms are found to have a significant influence on leaf water content, specific leaf area, and leaf nitrogen content. Relationships between gas exchange and these leaf traits yield linear correlations that are used to infer functional relationships impacted by the disease.
