Authors: Minixhofer Pia , Scharf Bernhard , Hafner Sebastian , Weiss Oliver , Henöckl Christina , Greiner Moritz , Room Thomas , Stangl Rosemarie
Published: January 2022

At conventional construction sites, the removal of soil and other excavated materials causes enormous mass movement, with a significant climate impact and contribution to global CO2 release. This study aimed to generate a Circular Soil concept for reusing excavated materials by creating engineered soils for landscape construction at large building sites. Engineered soils act as a substitute for natural soils and fulfill vital technical and soil functions when installing an urban green infrastructure (GI). In a field study, the vegetation performance on engineered soils was evaluated to establish a methodological approach, to assess the applicability of the Circular Soil concept. First, the technical specifications (grain-size distribution) were modeled for intensive green roof and turfgrass applications. Then, the soil components were optimized, mixed, installed and tested for greenery purposes, focusing on plant growth performance indicators (vitality, projective cover ratio and grass-herb ratio) to assess the vegetation performance. The results showed that the engineered soils match the performance of the reference soil alternatives. In conclusion, the Circular Soil concept has a high potential to contribute considerably to sustainable on-site soil management and the circular economy. It can be applied on a larger scale for urban GI development and sustainable resources management in the landscaping and construction sector.

Published: January 2022

The purpose is to study the geological resource planning and environmental impact assessments based on the geographic information system (GIS). In this study, the land resources of Yinan County in southeastern Shandong Province are taken as the research object. Based on a GIS, the current situation of land resource development is analyzed, land resource planning is carried out, and environmental impact mitigation measures are evaluated and analyzed through the environmental impact. The results obtained depict the distribution of cultivated land; the development area is 1617.31 hm2, of which 577.32 hm2 is cultivated land, 30.43 hm2 is garden land, 399.66 hm2 is forest land, 40.87 hm2 is urban and rural construction land, 10.11 hm2 is traffic water conservancy and other construction land, and 558.92 hm2 is natural reserve land. In the layout of the construction land, the development area is 841.94 hm2, of which 175.44 hm2 is cultivated land, 47.88 hm2 is garden land, 100.54 hm2 is forest land, 0.1 hm2 is other agricultural land, 90.45 hm2 is urban and rural construction land, 3.66 hm2 is traffic water conservancy and other construction land, 11.33 hm2 is water area, and 412.54 hm2 is natural reserve land. The impact of the implementation of planning on most indicators is positive and beneficial, while the impact of negative indicators is relatively small. It is revealed that the implementation of the plan has little impact on most of the ecological environment indicators. Construction and cultivated land development further improve the level of urbanization. In the process of planning implementation, corresponding measures should be taken to slow down or eliminate the negative development of the ecological environment.

Authors: Ren Wenhan , Ni Jing , Chen Yu
Published: January 2022

China’s management of marine ecological environments has experienced a development process that has gone from weak to strong. However, whether there are problems such as lack of systems, invalid systems, and system conflicts in the current management of marine ecological environments, and how to conduct collaborative governance among various complex subjects, remain to be answered. This paper first summarizes how China’s marine ecological environment management policy has evolved, which can be divided into five stages: the foundation stage (1949–1980), the initial establishment stage (1981–1995), the steady advancement stage (1996–2005), the deepening adjustment stage (2006–2010), and the strategic development stage (2011–present), and analyzes its characteristics at different stages. Then, this paper further explores the inherent dilemmas in the Chinese marine ecological environment management system. Finally, combined with the practical experience of marine ecological environment management in developed countries, this paper fully considers the division of responsibilities and mutual checks and balances of different subjects, flexibly configures various policy tools, and explores the mechanism of collaborative governance of marine ecological environment from the levels of government, market, the public and social organizations, so as to gradually improve the modern marine ecological environment management system and provide a reference for the government’s governance activities.
The Heritage Given: Cultural Landscape and Heritage of the Vistula Delta Mennonites as Perceived by the Contemporary Residents of the Region
Authors: Nowicka Klaudia
Published: January 2022

All tangible and intangible elements of cultural heritage that the past has conceded to local communities create unique landscapes shaped by tightly connected anthropogenic and natural factors. This heritage is a keystone of local identity which plays a significant role in politics, economic development, society and world view. In some regions, such as in the Vistula delta in Poland, the cultural heritage has been created by consecutive groups of settlers who represented different values, beliefs and ways of life. On the one hand, such a rich heritage may be perceived as a valuable asset and become a landmark or tourism product of a region. On the other hand, it may be perceived as alien and unwanted by contemporary residents, especially when they are not descendants of the former communities. The main objective of the study presented herein is to analyse how the residents of the Vistula delta region, called Żuławy Wiślane, perceive and use cultural heritage of the Mennonites, representing the most extraordinary group of settlers who used to live in the region. The analysis covers original data gathered during survey research in the period of 2017–2018 under the project Miniatura I “Perception and usage of cultural heritage of the Vistula delta Mennonites” financed by the National Science Centre in Poland.

Published: January 2022

Despite the great possibilities of modern neural network architectures concerning the problems of object detection and recognition, the output of such models is the local (pixel) coordinates of objects bounding boxes in the image and their predicted classes. However, in several practical tasks, it is necessary to obtain more complete information about the object from the image. In particular, for robotic apple picking, it is necessary to clearly understand where and how much to move the grabber. To determine the real position of the apple relative to the source of image registration, it is proposed to use the Intel Real Sense depth camera and aggregate information from its depth and brightness channels. The apples detection is carried out using the YOLOv3 architecture; then, based on the distance to the object and its localization in the image, the relative distances are calculated for all coordinates. In this case, to determine the coordinates of apples, a transition to a symmetric coordinate system takes place by means of simple linear transformations. Estimating the position in a symmetric coordinate system allows estimating not only the magnitude of the shift but also the location of the object relative to the camera. The proposed approach makes it possible to obtain position estimates with high accuracy. The approximate root mean square error is 7–12 mm, depending on the range and axis. As for precision and recall metrics, the first is 100% and the second is 90%.

Published: January 2022

Within the context of large-scale symmetry, a study on deep vision servo multi-vision tracking coordination planning for sorting robots was conducted according to the problems of low recognition sorting accuracy and efficiency in existing sorting robots. In this paper, a kinematic model of a mobile picking manipulator was built. Then, the kinematics design of the orwX, Y, Z three-dimensional space manipulator was carried out, and a method of deriving and calculating the base position coordinates through the target point coordinates, the current moving chassis center coordinates and the determined manipulator grasping attitude conditions was proposed, which realizes the adjustment of the position and attitude of the moving chassis as small as possible. The multi-vision tracking coordinated sorting accounts 79.8% of the whole cycle. The design of a picking robot proposed in this paper can greatly improve the coordination symmetry of logistic package target recognition, detection and picking.
Smooth Group L1/2 Regularization for Pruning Convolutional Neural Networks
Authors: Bao Yuan , Liu Zhaobin , Luo Zhongxuan , Yang Sibo
Published: January 2022

In this paper, a novel smooth group L1/2 (SGL1/2) regularization method is proposed for pruning hidden nodes of the fully connected layer in convolution neural networks. Usually, the selection of nodes and weights is based on experience, and the convolution filter is symmetric in the convolution neural network. The main contribution of SGL1/2 is to try to approximate the weights to 0 at the group level. Therefore, we will be able to prune the hidden node if the corresponding weights are all close to 0. Furthermore, the feasibility analysis of this new method is carried out under some reasonable assumptions due to the smooth function. The numerical results demonstrate the superiority of the SGL1/2 method with respect to sparsity, without damaging the classification performance.

Published: January 2022

Identifying the positive definiteness of even-order real symmetric tensors is an important component in tensor analysis. H-tensors have been utilized in identifying the positive definiteness of this kind of tensor. Some new practical criteria for identifying H-tensors are given in the literature. As an application, several sufficient conditions of the positive definiteness for an even-order real symmetric tensor were obtained. Numerical examples are given to illustrate the effectiveness of the proposed method.
High-Dimensional Conditional Covariance Matrices Estimation Using a Factor-GARCH Model
Authors: Li Xiaoling , Zhang Xingfa , Li Yuan
Published: January 2022

Estimation of a conditional covariance matrix is an interesting and important research topic in statistics and econometrics. However, modelling ultra-high dimensional dynamic (conditional) covariance structures is known to suffer from the curse of dimensionality or the problem of singularity. To partially solve this problem, this paper establishes a model by combining the ideas of a factor model and a symmetric GARCH model to describe the dynamics of a high-dimensional conditional covariance matrix. Quasi maximum likelihood estimation (QMLE) and least square estimation (LSE) methods are used to estimate the parameters in the model, and the plug-in method is introduced to obtain the estimation of conditional covariance matrix. Asymptotic properties are established for the proposed method, and simulation studies are given to demonstrate its performance. A financial application is presented to support the methodology.

Published: January 2022

Fungal endophytes occurring in grapevine (Vitis vinifera L.) are usually important sources of various compounds with biological activities with great potential for use in agriculture. Nevertheless, many species isolated from this plant belong to the genera Fusarium, Alternaria, or Aspergillus, all of which are well-known to produce mycotoxins. Our study is focused on the assessment of the toxinogenic potential of fungal endophytes isolated from vineyards in the Czech Republic. In total, 20 endophytic fungal species were cultivated in wine must, and 57 mycotoxins of different classes were analysed by liquid chromatography coupled with mass spectrometry. As a result, alternariol, tentoxin, meleagrin, roquefortine C, gliotoxin, and verruculogen were detected in the culture medium, of which verruculogen followed by gliotoxin were the most frequent (present in 90 and 40% of samples, respectively) and most concentrated (up to thousands ng/mL). The alternaria mycotoxins alternariol and tentoxin were detected not only in Alternaria sp. cultures, but traces of these mycotoxins were also quantified in the Diatripe and Epicoccum cultures. Meleagrin and roquefortine C were detected in Didymella sancta and Penicillium crustosum, gliotoxin was detected in Alternaria sp., Didymella sp., Aureobasidium pullulans, Cladosporium herbarum, Penicillium crustosum and Pleurophoma ossicola, and verruculogen was quantified in 99% of endophytic isolates investigated. The potential of endophytes to produce mycotoxins should be carefully checked, specifically in cases where they are intended for the purpose of V. vinifera growing.
Predictive Risk Mapping of Schistosomiasis in Madagascar Using Ecological Niche Modeling and Precision Mapping
Authors: Deka Mark A.
Published: January 2022

Schistosomiasis is a neglected tropical disease (NTD) found throughout tropical and subtropical Africa. In Madagascar, the condition is widespread and endemic in 74% of all administrative districts in the country. Despite the significant burden of the disease, high-resolution risk maps have yet to be produced to guide national control programs. This study used an ecological niche modeling (ENM) and precision mapping approach to estimate environmental suitability and disease transmission risk. The results show that suitability for schistosomiasis is widespread and covers 264,781 km2 (102,232 sq miles). Covariates of significance to the model were the accessibility to cities, distance to water, enhanced vegetation index (EVI), annual mean temperature, land surface temperature (LST), clay content, and annual precipitation. Disease transmission risk is greatest in the central highlands, tropical east coast, arid-southwest, and northwest. An estimated 14.9 million people could be at risk of schistosomiasis; 11.4 million reside in rural areas, while 3.5 million are in urban areas. This study provides valuable insight into the geography of schistosomiasis in Madagascar and its potential risk to human populations. Because of the focal nature of the disease, these maps can inform national surveillance programs while improving understanding of areas in need of medical interventions.

Published: January 2022

The central nervous system (CNS) HIV reservoir is an obstacle to achieving an HIV cure. The basal ganglia harbor a higher frequency of SIV than other brain regions in the SIV-infected rhesus macaques of Chinese-origin (chRMs) even on suppressive combination antiretroviral therapy (ART). Since residual HIV/SIV reservoir is associated with inflammation, we characterized the neuroinflammation by gene expression and systemic levels of inflammatory molecules in healthy controls and SIV-infected chRMs with or without ART. CCL2, IL-6, and IFN-γ were significantly reduced in the cerebrospinal fluid (CSF) of animals receiving ART. Moreover, there was a correlation between levels of CCL2 in plasma and CSF, suggesting the potential use of plasma CCL2 as a neuroinflammation biomarker. With higher SIV frequency, the basal ganglia of untreated SIV-infected chRMs showed an upregulation of secreted phosphoprotein 1 (SPP1), which could be an indicator of ongoing neuroinflammation. While ART greatly reduced neuroinflammation in general, proinflammatory genes, such as IL-9, were still significantly upregulated. These results expand our understanding of neuroinflammation and signaling in SIV-infected chRMs on ART, an excellent model to study HIV/SIV persistence in the CNS.

Published: January 2022

Understanding the groundwater chemical regime on irrigated lands is relevant for assessing hydrogeological and reclamation processes. Water chemistry, natural and climatic conditions, and drainage characteristics define the complex hydrochemical connections which are formed between irrigation waters, soil, and water of the unsaturated zone and groundwater. This research paper presents the results of studies of seasonal changes in the chemical composition of groundwater in the Karatal irrigated massif. A detailed analysis of the salt regime and chemical composition of groundwater have been performed based on a large number of samples for 2019. Besides, data related to the Karatal River and drainage waters quality inside the basin have also been analyzed. Results demonstrate that the salinization processes in the massif are determined by hydrogeological conditions and drainage availability. In the north-eastern part of the massif, a high risk of soil salinization has been observed as a consequence of all the salinization processes which are determined by its hydrogeological conditions and drainage availability. Data analysis over soil samples and irrigation and drainage waters show that the hydrochemical regime of groundwater on Karatal irrigation massif is influenced by the presence of saline soil-forming rocks, the groundwater depth, the volume, and the quality of irrigation waters, the characteristics of the natural drainage, and evaporation processes.
Mitigation of Hydroelastic Responses in a Very Large Floating Structure by a Connected Vertical Porous Flexible Barrier
Authors: Pu Jun , Lu Dong-Qiang
Published: January 2022

The hydroelastic response of an elastic thin plate combined with a vertical porous flexible plate floating on a single- or a two-layer fluid is analyzed in the two-dimensional Cartesian coordinate system. The vertical and the horizontal plates are placed in an inverted-L shape and rigidly connected together. The problem is studied with the aid of the method of matched eigenfunction expansions within the framework of linear potential flow theory. The fluid is assumed to be inviscid and incompressible, and the motion is assumed to be irrotational. Time–harmonic incident waves of the traveling mode with a given angular frequency are considered. Then, the least-squares approximation method and the inner product are used to obtain the expansion coefficients of the velocity potentials. Graphical results show the interaction between the water waves and the structure. The effects of several physical parameters, including the length and the complex porous-effect parameter of the vertical plate, on the wave reflection and transmission are discussed. The results show that a vertical plate can effectively eliminate the hydroelastic response of the very large floating structure. The longer a vertical plate is, the more waves are reflected by the vertical plate. With the increase in the porous-effect parameter, the deflection of vertical plate decreases. Besides the effects of the flexural rigidity, the lateral stress, the mooring line angle, the fluid density ratio, and the position of interface on the wave reflection and transmission are discussed. Numerical results show the significant mitigation effect due to the presence of the additional vertical plate.

Published: January 2022

Background

Systemic cytokines are elevated in patients with chronic kidney disease (CKD) and on hemodialysis compared with the general population. However, whether cytokine levels interfere with vascular remodeling, increasing the risk of arteriovenous fistula (AVF) failure, remains unknown.

Methods

This is a case-control study of 64 patients who underwent surgery for AVF creation (32 with AVF maturation failure and 32 matching controls with successful maturation). A total of 74 cytokines, including chemokines, interferons, interleukins, and growth factors, were measured in preoperative plasma samples using multiplex assays. Sixty-two patients were included in the statistical analyses. Associations with AVF failure were assessed using paired comparisons and conditional logistic regressions accounting for paired strata.

Results

Seven cytokines were significantly higher in patients with AVF maturation failure than in matching controls (G-CSF, IL-6, MDC, RANTES, SDF-1α/β, TGFα, and TPO). Of these, G-CSF (odds ratio [OR]=1.71; 95% confidence interval [95% CI], 1.05 to 2.79 per 10 pg/ml), MDC (OR=1.60, 95% CI, 1.08 to 2.38 per 100 pg/ml), RANTES (OR=1.55, 95% CI, 1.10 to 2.17 per 100 pg/ml), SDF-1α/β (OR=1.18, 95% CI, 1.04 to 1.33 per 1000 pg/ml), and TGFα (OR=1.39, 95% CI 1.003, 1.92 per 1 pg/ml) showed an incremental association by logistic regression.

Conclusions

This study identified a profile of plasma cytokines associated with adverse maturation outcomes in AVFs. These findings may open the doors for future therapeutics and markers for risk stratification.

This study mapped the areal extent, identified the species composition, and analyzed the changes of salt marshes in the intertidal zone of China during the period 1985–2019. With the aid of the cloud platform of the Google Earth Engine, we selected Landsat 5/8 and Sentinel-2 images and used the support vector machine classification method to extract salt marsh information for the years of 1985, 1990, 1995, 2000, 2005, 2010, 2015, and 2019. Seven major species of salt marshes:
Phragmites australis
,
Suaeda
spp.,
Spartina alterniflora
,
Scirpus mariqueter
,
Tamarix chinensis
,
Cyperus malaccensis
, and
Sesuvium portulacastrum
were identified. Our results showed that salt marshes are mainly distributed in Liaoning, Shandong, Jiangsu, Shanghai, and Zhejiang, with varying patterns of shrinking, expansion, or wavering in different places. The distribution of salt marshes has declined considerably from 151,324 ha in 1985 to 115,397 ha in 2019, a drop of 23.7%. During the same period, the area of native species has dropped 95.4% from 77,741 ha to 3,563 ha for
Suaeda
spp. and 45.1% from 60,511 ha to 33,193 ha for
P. australis
; on the contrary, the area of exotic species,
S. alterniflora
, has exhibited a sharp rise from just 99 ha to 67,527 ha. For the past 35 years, the driving factors causing salt marsh changes are mainly land reclamation, variations in water and sand fluxes, and interspecific competition and succession of salt marsh vegetation. These results provide fundamental reference information and could form the scientific basis for formulating policies for the conservation and utilization of salt marsh resources in China.
Определение параметров модели системы стабилизации ракеты в процессе полета
Authors: Авдеев Вольт Васильевич
Published: January 2022

Динамические характеристики системы объект управления и регулятор в значительной степени зависят от выбора закона регулирования, определяемого номинальными значениями параметров математической модели процесса стабилизации и его приоритетным показателем. Из-за отклонения параметров ракеты и, соответственно, модели от номинальных величин проектанты устанавливают коэффициенты запаса, исходя из наиболее неблагоприятных условий, что отрицательно сказывается на общих показателях, в частности на относительном весе полезной нагрузки. Поэтому возникает потребность в разработке алгоритмов уточнения - идентификации в процессе полета параметров модели с помощью сигналов устройств измерения и возможности бортовых вычислительных машин. Это повысит эффективность использования методов выбора закона регулирования с точки зрения таких показателей, как запас устойчивости, точность стабилизации и мощность исполнительного устройства. Целью статьи является разработка методов уточнения параметров модели системы стабилизации движения ракеты в плоскости риска, опирающихся на использование текущих данных измерительных устройств части координат вектора состояния, и проверка эффективности уточнения с точки зрения указанных показателей. Принята линейная стационарная в окрестности определенной точки траектории модель системы стабилизации возмущенного движения ракеты с учетом инерции исполнительного устройства в виде обычных дифференциальных уравнений пятого порядка. Для приближения параметров модели к их фактическим значениям предложено два подхода: 1) в пространстве параметров модели находится минимум интеграла расстояния между точками траектории согласно сигналам измерительных устройств и траектории, полученной путем моделирования процесса компенсации возмущения; 2) фактические значения параметров являются результатом решения системы нелинейных уравнений, включающих данные измерительных устройств и соответствующие данные, полученные путем моделирования. На примере параметров ракеты космического назначения показано, что выбор закона регулирования, исходя из фактических коэффициентов модели, приводит к существенному уменьшению отклонений от заданного значения запаса устойчивости системы, погрешности стабилизации и мощности исполнительного устройства.
Покращення моделей розпізнавання облич за допомогою навчання подібності, розкладу зміни темпу навчання та аугментацій
Authors: Літвінчук Андрій Миколайович , Барановська Леся Валеріївна
Published: January 2022

Розпізнавання облич — одна з основних задач комп’ютерного зору, актуальна в силу її практичної значущості та викликає велику зацікавленість широкого кола науковців. І хоча дослідження у сфері відбувались з початку розвитку комп’ютерного зору, адекватних результатів змогли досягнути лише за допомогою згорткових нейронних мереж. У даній роботі проведено порівняльний аналіз методів розпізнавання обличчя до згорткових нейронних мереж. Розглянуто метод навчання подібності, аугментації та розклади зміни темпу навчання. Проведено ряд експериментів, виконано порівняльний аналіз розглянутих методів покращення згорткових нейронних мереж, у результаті отримано універсальний алгоритм для навчання моделі розпізнавання облич. У роботі використано SE-ResNet50 як єдину мережу для експериментів. Навчання подібності — це метод, за допомогою якого можливо досягнути достатньої точності. Перенавчання є серйозною проблемою для нейронних мереж, зокрема тому, що мають дуже багато параметрів, а даних зазвичай не настільки багато, щоб гарантувати узагальнюючу можливість моделі. Додаткова розмітка даних може займати багато часу і бути доволі дорогою, тому виник такий підхід, як аугментації. Аугментації штучно збільшують тренувальний набір даних, тому цілком природньо, що метод аугментації у всіх експериментах покращив результати відносно початкового експерименту. Різні степені та більш агресивні форми аугментації у задачі розпізнавання облич у даній роботі приводив до кращих результатів. Як і очікувалось, найкращим розкладом зміни темпу навчання виявився косинусний з розігрівом та оновленнями. Цей розклад має мало параметрів, до того ж зручний у використанні. Загалом, використовуючи різні підходи, отримали точність 93,5 % на досить складному наборі даних, що на 22 % краще за базовий експеримент. У наступних дослідженнях планується розглянути покращення не лише моделі розпізнавання облич, а й детекції. Від якості детекції обличчя безпосередньо залежить точність розпізнавання.

Authors: Yakovleva E.N.
Published: January 2022

In the 21st century, climate change is becoming a key constraint on the sustainable development of industries, regions, countries, and the world community as a whole. Climate risk management therefore requires increased financial support, both to compensate for the damage caused by hydrometeorological hazards and to implement policies to reduce anthropogenic greenhouse gas emissions and adapt to changes. The article examines the main sources of financing for climate security management in Russia and foreign countries. Their positive aspects and problems of practical use have been identified. Each financial instrument is considered from the point of view of regulatory influence on subjects of market economy and climate risks. It has been shown that a number of elements of fiscal policy used on an ongoing basis or as an experiment in Russia require refinement or replacement. Practical recommendations for improving the situation are proposed, including the use of innovative tools for our country (climate innovation bank, weather and temperature options, etc.). The author's recommendations are aimed at changing the vector of climate regulation from state paternalism to the application of entrepreneurial initiative by creating effective market incentives. The result will be not only a decrease in greenhouse gas emissions and energy intensity of the economy, but also an increase in profitability and competitiveness, the investment attractiveness of organizations, territorial entities, the country, as well as an increase in the employment and well-being of the population and national wealth of the Russian Federation.

La guía de expertos es un directorio que agrupa a los investigadores de una institución dispuestos a colaborar con los medios de comunicación y que permite a los periodistas localizarles de forma autónoma en un corto espacio temporal. Una herramienta comunicacional que permite optimizar la proyección mediática del capital intelectual de la organización, aumentando la visibilidad, marca y reputación de la institución. En este contexto, se investiga su presencia y gestión en las universidades privadas españolas. Los objetivos son averiguar su presencia o ausencia; identificar los motivos que han frenado su implementación digital; analizar su ubicación, tipo de formato e idiomas; investigar cómo se localiza a un experto/a; analizar los datos curriculares ofrecidos del investigador/a; desvelar qué datos curriculares ofrecen del experto/a; y dar a conocer las modalidades para contactar con el especialista. La metodología se basa en un análisis de contenido y el periodo de estudio es de febrero a junio de 2020. Los resultados indican una escasa presencia, si bien, siempre se ubican en las salas de prensa y su formato suele ser digital (no en pdf), permitiendo la búsqueda por nombre-apellidos o especialidad, principalmente sólo en español, ofreciendo poca información curricular de los investigadores y permitiendo contactar siempre a través del teléfono o e-mail institucional mediante un contacto tanto directo como mediado por el gabinete de comunicación. Se concluye con una visión global de su implementación y una identificación de las disfunciones y buenas praxis detectadas para transferir el conocimiento científico mediante esta herramienta organizacional.
