Комплексный анализ мультиспектральных данных, полученных в разные периоды вегетации, позволяет реконструировать современное состояние антропогенно-преобразованной природной среды и выявлять участки исторического природопользования. Неоднозначность проявления следов вторичной сукцессии лесных массивов требует сопоставления на разносезонных изображениях изменений спектральных признаков растительности и особенностей текстуры ландшафтных объектов. Методическая основа таких исследований - алгоритм обработки мультиспектральных данных, адаптированный для применения текстурных признаков Харалика на этапе извлечения признаков изображения. Совместная сегментация массивов разносезонной мультиспектральной съёмки «сглаживает» локальные, менее значимые изменения текстуры ландшафтных объектов, что позволяет более контрастно продемонстрировать обобщающие тенденции распределения растительности. Территория обследования включала фрагмент дачи Пудемского железоделательного завода, где в первой половине XIX в. производились вырубки строевого и дровяного леса для нужд производства. Сегментированное изображение демонстрирует принципиальные отличия растительного покрова западной и восточной частей территории обследования: участка исторических лесосек и части дачи, которая не подвергалась интенсивному антропогенному воздействию.
A comprehensive analysis of multispectral data obtained in different growing periods makes it possible to reconstruct the current state of the anthropogenically transformed natural environment and identify areas of historical nature management. Ambiguous displaying of secondary succession of forests requires comparison of changes in the spectral features of vegetation and features of the landscape objects texture in multi-season images. The methodological basis of such studies is an algorithm of multispectral data processing adapted to apply Haralick's textural features at the feature extraction stage. Joint segmentation of multi-seasonal multispectral images “smoothes out” local, less significant changes in the texture of landscape objects, which makes it possible to more clearly demonstrate the general trends in the distribution of vegetation. The area of interest included a fragment of the Pudemskiy ironworks dacha, where “timber and firewood forests” were cut down for the production needs in the 1st half of the 19th century. The segmented image demonstrates the fundamental differences between the vegetation cover of the western and eastern parts of the survey area: the site of historical cutting areas and the part that was not subjected to an intense anthropogenic impact.
EFFECT OF MULTIPLICATIVE NOISE ON THE COHERENT SIGNAL FREQUENCY MEASUREMENT AGAINST THE BACKGROUND OF WHITE NOISE
Authors: АРТЮШЕНКО В.М. , ВОЛОВАЧ В.И. 
Published: July 2024

Рассмотрено и проанализировано влияние мультипликативных помех, действующих одновременно с белым шумом, на точность измерения частоты когерентного сигнала, заданного в виде последовательности когерентных импульсов. Определено условие отсутствия систематических ошибок на выходе следящего измерителя. Найдены крутизна его дискриминационной характеристики, спектральная плотность флюктуаций на выходе дискриминатора и коэффициенты, определяющие нормирующее действие автоматической регулировки усиления. Названные величины задают величину ухудшения точностных характеристик измерителя при воздействии мультипликативных помех. Показано, что влияние мультипликативной помехи возрастает при уменьшении уровня неискажённой части сигнала и при увеличении отношения энергии сигнала, когерентно накапливаемой в линейных цепях дискриминатора, к спектральной плотности мощности аддитивной помехи. Показано, что влияние мультипликативных помех проявляется наиболее сильно в тех случаях, когда ширина спектра функции помеховой модуляции соизмерима с полосой пропускания линейных цепей дискриминатора.
The effect of multiplicative noise acting simultaneously with white noise on the accuracy of measuring the frequency of a coherent signal given as a sequence of coherent pulses is considered and analyzed. The condition for the absence of systematic errors at the output of the tracking meter is determined. The steepness of its discrimination characteristic, the spectral density of fluctuations at the discriminator output, and the coefficients that determine the normalizing action of automatic gain control are found. These values determine the amount of deterioration in the accuracy characteristics of the meter under the influence of multiplicative noise. It is shown that the influence of multiplicative noise increases with a decrease in the level of the undistorted part of the signal and with an increase in the ratio of the signal energy coherently accumulated in the linear circuits of the discriminator to the power spectral density of additive noise. It is shown that the effect of multiplicative noise is most pronounced in those cases where the width of the spectrum of the noise modulation function is commensurate with the bandwidth of the linear circuits of the discriminator.

Published: July 2024

Globally, performative spaces and venues of artistic creativity are governed by sets of conventions which impact the creative process. In this article, we discuss the experiences of four different creatives, operating in four different creative spaces. A poet and football player, a theatre producer and script writer, a gallery curator, and a ballet dancer have all shared their experiences of how traditionally white and heteronormative discourses regulate their respective creative spaces, the ways they conform to or transgress these norms, and the ways their interactions with their chosen creative spaces affect their creativity. These creatives have identities which are somehow ‘marked’, somehow ‘different’ from the ‘norms’ Wales and South-West England. Whether members of the LGBTQ+ community, migrants to Wales from European and Caribbean countries, or being a different race to many around them, the creatives all have complicated interactions with the norms of their creative spaces within Wales and South-West England. These creative’s identities often clash with an entrenched lack of diversity and the broader expectations of British society. Despite, or perhaps, because of, these conflicts and tensions, each of the creatives discussed here found immense joy in the relationship between their identity/ies and their creative spaces and discovered how their own identity/ies are a central driving force for their creativity. Regardless of the differences of their mediums, each creative interviewed sought to centre their identity, to help them create art which can challenge dominant white and heteronormative discourses in wider British society.

Published: July 2024

En el agronegocio del vino, las representaciones colectivas, como los sistemas de indicaciones geográficas, se crean para proteger la calidad y diferenciar cada región productora en el mercado nacional e internacional. En la actualidad, la diversidad del escenario vitivinícola global, las nuevas demandas de los consumidores y los cambios socioambientales están invitando a repensar este tipo de sistemas de protección de la calidad y a enriquecer el debate en relación con las posibles alternativas a estos. En ese contexto, el presente trabajo explora las opiniones acerca de dicho debate desde regiones y países vitivinícolas emergentes, como es el caso de Sonora, en México. Estos espacios se encuentran en una fase de crecimiento, experimentación y desarrollo que permite analizar cómo se percibe la posibilidad de adoptar y regular modelos de protección geográfica y los desafíos asociados a este tipo de estrategias de clasificación y valorización. Asimismo, a nivel más amplio, este análisis busca reflexionar respecto a la creación de formas alternativas de diferenciar y representar colectivamente la calidad y el valor asociado al lugar de origen de la producción vitivinícola. Lo anterior, finalmente, con el objetivo de comprender en profundidad los cambios a los que se enfrenta la diversificación y transformación de la industria vitivinícola actual en América Latina y a nivel global.

Published: July 2024

The difference in the spectral composition of artificial and natural lighting can negatively affect health, as well as lead to a distorted perception of the color of surrounding objects. At the same time, a certain correction of the spectral composition of visible radiation in medical institutions and workplaces has a positive effect on human health, while can be carried lighting control out taking into account the data of personal sensor devices that determine the human condition. The purpose of the research was to select criteria for comparing natural and LED optical and visible radiation by spectral composition and by the visibility of color differences in natural and LED lighting. The effectiveness of the application of known and developed criteria for assessing the difference in the spectral composition of optical and visible radiation from natural and LED sources was investigated, as well as for the visibility of color differences in natural and LED lighting. To minimize the values of criteria are proposed additive and subtractive methods for calculating LED parameters. Their comparison allowed us to conclude that a more complex calculation algorithm, but higher performance for an additive technique than for a subtractive one with the same minimization results.It was found that to simulate the spectral composition of natural radiation using LEDs, it is most effective to use the criteria "standard deviations of the relative differences between the optical and visible spectral components of natural and LED radiation". A comparison of the criteria for the visibility of color differences in natural and LED lighting showed approximately the same effectiveness of using the criteria "small color differences" and "standard deviation by photoreceptors" at the present stage and the prospects for applying the second criterion, provided that its acceptable values are established.

Authors: Peng Lei , Shi Min , Liu Qian , Fan Xiufang , Li Juan , Li Xia 
Published: July 2024

Abstract

Background To determine the association of calcified necrotizing funisitis with adverse neonatal outcomes.
Method This retrospective study included newborns who had undergone pathological examination between July 2020 and March 2024. Twenty-one neonates who delivered at Jinan Maternal and Child Health Hospital with pathological results of calcified NF were retrospectively selected as the study subjects, and 44 neonates who were admitted during the same period without pathological results of calcified NF were selected as the control group according to a gestational age ratio of 1:2. Neonatal outcome measures were comparable between the two groups.
Results Two groups were born preterm. Compared to those in the control group, the mode of delivery (cesarean vs vaginal), prolonged PROM, RDS, ROP, duration of ventilator use, white cell count, CRP, and neutrophil percentage in the observation group were significantly different from those in the control group (P<0.05). Among the 21 individuals analyzed, 14 patients (66.7%) were determined to be positive for UU infection in the observation group, and 4 patients (9.50%) were positive in the control group. The differences were statistically significant (P<0.001).
Conclusion Blood cell counts, CRP levels and neutrophil proportions were markedly elevated. The rates of RDS and ROP decreased. The duration of invasive mechanical ventilation use was prolonged in neonates with calcified necrotizing funisitis. UU was a risk factor for calcified NF.

Published: July 2024

Abstract

Understanding the impacts of climate change on wind patterns and wind power potential is crucial for energy planning and resource management, particularly in regions highly vulnerable to climate variability, such as the Middle East. In this study, we utilized a COSMO-CLM regional climate model simulation at an 8km grid spacing to investigate the changes in summer wind patterns over the Middle East and their implications for wind energy potential.
Our analysis revealed that COSMO-CLM can effectively capture the broad-scale summer wind patterns over the Middle East. However, considerable uncertainties were observed over coastal and mountainous regions, highlighting the complexity of local wind dynamics. Notably, until 2070, we have identified significant increases of up to 0.7 ms−1 in median surface wind speeds across the Middle East, driven primarily by land-sea temperature contrasts. However, at the 150-meter level, we have observed significant decreases of up to 1.0 ms−1 in median wind speed attributed to changes in frequency and intensity of the Persian Trough synoptic system in a changing climate. Regionally, this decreases median potential wind energy up to 7 GJ within six hours. These findings underscore the importance of considering surface and upper-level wind characteristics when assessing climate change impacts on wind energy resources. Furthermore, our study reveals a spatially heterogeneous pattern of changes in wind energy potential across the region. While decreases in wind energy are evident over much of the Middle East, particularly in inland areas and over the Mediterranean Sea, we have also observed some increases in potential, notably over the Red Sea.
In summary, our study highlights significant changes in wind characteristics in a changing climate, with implications for the future energy mix in the Middle East. These findings provide valuable insights for policymakers and energy planners aiming to harness wind energy resources sustainably in the face of climate change challenges.

Published: July 2024

Abstract

Background
Uracil metabolism is an important step in the growth and metabolism of Streptococcus pneumoniae, and pyrimidine nucleotides play an important role in the expression and production of S. pneumoniae capsules. MgaSpn(spd_1587),as a transcriptional ragulator of host environment adaptation, regulates the biosynthesis of the capsules and phosphorylcholine. However, the underlying regulation mechanism between uracil metabolism and biosynthesis of capsules remains incompletely understood. Here, we first described the relationship between uracil metabolism and capsule expression via the pyrR gene(spd_1134) in S. pneumoniae.
Results
Electrophoretic mobility-shift assays (EMSAs) and DNase I footprinting assays showed a direct interaction between MgaSpn and the pyrR promoter (PpyrR) at two specific binding sites. MgaSpn negatively regulated capsule production through pyrR as confirmed by complementing pyrR expression in D39ΔmgaSpnΔpyrR. Virulence experiments showed that the MgaSpn-pyrR interaction was necessary for both pneumococcal colonization and invasive infection.
Conclusions
For the first time, the present study demonstrated that the de novo synthesis gene pyrR of S. pneumoniae is regulated by the MgaSpn transcriptional regulator.Taken together,these results provide an insight into the regulation of capsule production mediated by uracil metabolism and its important roles in pneumococcal pathogenesis.

Published: July 2024

Abstract

In cloud computing environment data redundancy and data integrity management are the consequential issues. They result in huge space wastage and compromises data security and data accuracy. Data deduplication and data auditing are the techniques used to efficiently reduce storage space and to verify the integrity of the cloud stored data. Most of the existing data deduplication and auditing algorithms are mainly focusing on static data storage environment which does not efficiently fits to the dynamic nature of cloud storage. Integrating data deduplication with integrity verification is very challenging to handle and such existing systems suffers from faking of audit results and data ownership leakage. Also, existing cloud data auditing schemes does not provide compensation to users, if their data integrity is compromised. Blockchain technology with its key features, provides security, trust and efficiency to handle data storage in cloud. In order to solve the issues in existing data auditing integrated deduplication systems, this paper proposes Blockchain incorporated secure cloud data storage system supporting data auditing and deduplication with fair remittance. The implementation results and security analysis confirm that the proposed system outperforms well in terms of data integrity verification and deduplication with enhanced accuracy and security compared to state of the arts.
