Prediction and Optimization Analysis of the Performance of an Office Building in an Extremely Hot and Cold Region
Authors: Liu Yunbo , Wang Wanjiang , Huang Yumeng
Published: May 2024

The White Paper on Peak Carbon and Carbon Neutral Action 2022 states that China is to achieve peak carbon by 2030 and carbon neutrality by 2060. Based on the “3060 dual-carbon” goal, how to improve the efficiency of energy performance is an important prerequisite for building a low-carbon, energy-saving, green, and beautiful China. The office performance building studied in this paper is located in the urban area of Turpan, where the climate is characterized by an extremely hot summer environment and a cold winter environment. At the same time, the building is oriented east–west, with the main façade facing west, and the main façade consists of a large area of single-layer glass curtain wall, which is affected by western sunlight. As a result, there are serious problems with the building’s energy consumption, which in turn leads to excessive carbon emissions and high life cycle costs for the building. To address the above problems, this paper analyzes and optimizes the following four dimensions. First, the article creates a Convolutional Neural Network (CNN) prediction model with Total Energy Use in Buildings (TEUI), Global Warming Potential (GWP), and Life Cycle Costs (LCC) as the performance objectives. After optimization, the R2 of the three are 0.9908, 0.9869, and 0.9969, respectively, thus solving the problem of low accuracy of traditional prediction models. Next, the NSGA-II algorithm is used to optimize the three performance objectives, which are reduced by 41.94%, 40.61%, and 31.29%, respectively. Then, in the program decision stage, this paper uses two empowered Topsis methods to optimize this building performance problem. Finally, the article analyzes the variables using two sensitivity analysis methods. Through the above research, this paper provides a framework of optimization ideas for office buildings in extremely hot and cold regions while focusing on the four major aspects of machine learning, multi-objective optimization, decision analysis, and sensitivity analysis systematically and completely. For the development of office buildings in the region, whether in the early program design or in the later stages, energy-saving measures to optimize the design have laid the foundation of important guidelines.

Published: May 2024

Continuous non-invasive blood pressure (CNBP) monitoring is of the utmost importance in detecting and managing hypertension, a leading cause of death in the United States. Extensive research has delved into pioneering methods for predicting systolic and diastolic blood pressure values by leveraging pulse arrival time (PAT), the time difference between the proximal and distal signal peaks. The most widely employed pairing involves electrocardiography (ECG) and photoplethysmography (PPG). Possessing similar characteristics in terms of measuring blood flow changes, a recently investigated optical signal known as speckleplethysmography (SPG) showed its stability and high signal-to-noise ratio compared with PPG. Thus, SPG is a potential surrogate to pair with ECG for CNBP estimation. The present study aims to unlock the untapped potential of SPG as a signal for non-invasive blood pressure monitoring based on PAT. To ascertain SPG’s capabilities, eight subjects were enrolled in multiple recording sessions. A third-party device was employed for ECG and PPG measurements, while a commercial device served as the reference for arterial blood pressure (ABP). SPG measurements were obtained using a prototype smartphone-based system. Following the completion of three scenarios—sitting, walking, and running—the subjects’ signals and ABP were recorded to investigate the predictive capacity of systolic blood pressure. The collected data were processed and prepared for machine learning models, including support vector regression and decision tree regression. The models’ effectiveness was evaluated using root-mean-square error and mean absolute percentage error. In most instances, predictions utilizing PATSPG exhibited comparable or superior performance to PATPPG (i.e., SPG Rest ± 12.4 mmHg vs. PPG Rest ± 13.7 mmHg for RSME, and SPG 8% vs. PPG 9% for MAPE). Furthermore, incorporating an additional feature, namely the previous SBP value, resulted in reduced prediction errors for both signals in multiple model configurations (i.e., SPG Rest ± 12.4 mmHg to ±3.7 mmHg for RSME, and SPG Rest 8% to 3% for MAPE). These preliminary tests of SPG underscore the remarkable potential of this novel signal in PAT-based blood pressure predictions. Subsequent studies involving a larger cohort of test subjects and advancements in the SPG acquisition system hold promise for further improving the effectiveness of this newly explored signal in blood pressure monitoring.

Nuclear reactions are responsible for the chemical evolution of stars, galaxies and the Universe. Unfortunately, at temperatures of interest for nuclear astrophysics, the cross-sections of the thermonuclear reactions are in the pico- femto-barn range and thus measuring them in the laboratory is extremely challenging. In this framework, major steps forward were made with the advent of underground nuclear astrophysics, pioneered by the Laboratory for Underground Nuclear Astrophysics (LUNA). The cosmic background reduction by several orders of magnitude obtained at LUNA, however, needs to be combined with high-performance detectors and dedicated shieldings to obtain the required sensitivity. In the present paper, we report on the recent and future detector-shielding designs at LUNA.

Ad26.COV2.S vaccination can lead to vaccine-induced immune thrombotic thrombocytopenia (VITT), a rare but severe adverse effect, characterized by thrombocytopenia and thrombosis. The mechanism of VITT induction is unclear and likely multifactorial, potentially including the activation of platelets and endothelial cells mediated by the vaccine-encoded spike protein (S protein). Here, we investigated the biodistribution of the S protein after Ad26.COV2.S dosing in three animal models and in human serum samples. The S protein was transiently present in draining lymph nodes of rabbits after Ad26.COV2.S dosing. The S protein was detected in the serum in all species from 1 day to 21 days after vaccination with Ad26.COV2.S, but it was not detected in platelets, the endothelium lining the blood vessels, or other organs. The S protein S1 and S2 subunits were detected at different ratios and magnitudes after Ad26.COV2.S or COVID-19 mRNA vaccine immunization. However, the S1/S2 ratio did not depend on the Ad26 platform, but on mutation of the furin cleavage site, suggesting that the S1/S2 ratio is not VITT related. Overall, our data suggest that the S-protein biodistribution and kinetics after Ad26.COV2.S dosing are likely not main contributors to the development of VITT, but other S-protein-specific parameters require further investigation.
Impact of Engine Inertia on P2 Mild HEV Fuel Consumption
Authors: Yakhshilikova Gulnora , Ruzimov Sanjarbek , Tonoli Andrea , Mukhitdinov Akmal
Published: May 2024

The energy management system (EMS) of a hybrid electric vehicle (HEV) is an algorithm that determines the power split between the electrical and thermal paths. It defines the operating state of the power sources, i.e., the electric motor (EM) and the internal combustion engine (ICE). It is therefore one of the main factors that can significantly influence the fuel consumption and performance of hybrid vehicles. In the transmission path, the power generated by the ICE is in part employed to accelerate the rotating components of the powertrain, such as the crankshaft, flywheel, gears, and shafts. The main inertial components are the crankshaft and the flywheel. This additional power is significant during high-intensity acceleration. Therefore, the actual engine operation is different from that required by the power split unit. This study focuses on exploring the influence of engine inertia on HEV fuel consumption by developing a controller based on an equivalent consumption minimisation strategy (ECMS) that considers crankshaft and flywheel inertia. The optimal solution obtained by the ECMS controller is refined by incorporating the inertia effect of the main rotating components of the engine into the cost function. This reduces the engine operation during high inertial torque transient phases, resulting in a decrease in vehicle CO2 emissions by 2.34, 2.22, and 1.13 g/km for the UDDS, US06, and WLTC driving cycles, respectively.

Demokrat Parti iktidarının ortalarından itibaren finansman kaynağında yaşanan sıkıntılara bağlı olarak yatırımların durması gündelik hayatta olumsuz sonuçlar doğurmuştur. Bu olumsuz sonuçlardan bazıları döviz kurunda meydana gelen artış, ithal ürün fiyatlarının artması, gıda ve giyim sektöründe fiyat artışı ve mal darlığının yaşanması olmuştur. Ekonomide yaşanan bu olumsuz gelişmeler alım gücü son derece düşmüş olan vatandaşları uygun fiyata satılmakta olan kaçak ürünlere yönlendirmiştir. Haliyle kaçak ürünlere artan talep beraberinde kaçakçılık faaliyetlerinin de artmasına yol açmıştır. Hükümet ise bir yandan hayat pahalılığını ortadan kaldırmak için ekonomik politikaları hayata geçirmeye çalışırken diğer tarafından da kaçakçılıkla mücadelede birtakım tedbirler almıştır. Bu bağlamda alınan tedbirler doğrultusunda Jandarma Genel Komutanlığı’nın 1955-1958 yılları arasında Türkiye’de yürütmüş olduğu mücadele neticesinde meydana gelen kaçakçılık vakaları, bu vakalara düzenlenen askeri operasyonlar, bu operasyonlar neticesinde ele geçirilen kaçak malların türleri ve miktarları, yakalanan kaçakçıların miktarı ile kaçakçılık faaliyetlerinin gerçekleştiği bölgeleri tespit etmek çalışmamızın temel amacını teşkil etmektedir. Jandarma Genel Komutanlığı’nın tutmuş olduğu raporlar ve arşiv belgelerinin yanı sıra telif eserlerden istifade edilerek yürütülen bu çalışma neticesinde dört yıllık zaman zarfında 9.905 kaçakçılık vakasının meydana geldiği, 7.505 sağ, yaralı veya ölü kaçakçının yakalandığı, 19.852.504 Türk lirası değerinde kaçak malın ele geçirildiği tespit edilmiştir. Ülke güvenliği ve hazine gelirleri için tehdit olarak algılanan kaçakçılığı ortadan kaldırma hususunda Jandarma Genel Komutanlığı’na önemli rol düştüğü algılanmıştır. Komutanlık tarafından kaçakçılara yönelik operasyonların kesintisiz şekilde devam ettirildiği saptanmıştır. Ele geçirilen mallara dair istatistiki verilerin analizi sonucunda ise kaçakçılığın tam anlamıyla önlenemediği ifade edilmiştir.

The Driving Effects of Ecosystem Services on Urban Ecological Resilience in Urban Agglomeration
Authors: Zhang Qiongrui , Ma Hongzhi , Zhu Xuetong , Xu Songjun
Published: May 2024

Urban ecological resilience (UER) is a fundamental requirement for sustainable urban development. Ecosystem services (ESs) support urban resilience in many ways; however, it remains unknown how the various ES types affect UER. In this study, 10 ESs were selected to characterize the 4 types of ES in the Pearl River Delta urban agglomeration (PRD), and the InVEST model, CASA model, and nuclear density analysis were used to evaluate the various ESs. We used a morphological resilience–density resilience–economic resilience framework to assess UER, and the structure equation model was used to explore the effects of ESs on UER. Results showed that: (a) Supporting ecosystem service significantly and positively drives UER through the provision ecosystem service and regulation ecosystem service, while supporting ecosystem service has a negative effect on cultural ecosystem service, and cultural ecosystem service has no significant effect on UER. (b) In 2020, except for water yield, water purification, nature education, and recreation service, the distributions of ESs in the periphery of the study area were higher than those in the central. (c) In the PRD, counties with high economic resilience tend to have lower morphological resilience and density resilience. This empirical study examined the driving effects of various ESs on UER and validated the multilevel guarantee of ESs for urban ecology, which can provide more effective references for the sustainable development of urban agglomerations.
Impacts of Land Use and Climate Change on Water-Related Ecosystem Service Trade-offs in the Yangtze River Economic Belt

Published: May 2024

Land use/cover change (LUCC) and climate change have important influences on ecosystem services (ESs) and their interactions, particularly in regions with rapid socioeconomic development. However, little research has distinguished the impacts of these 2 factors on ES interactions. Therefore, the impacts of LUCC and climate change on water-related ecosystem service (WES) trade-offs in the Yangtze River Economic Belt (YREB) were measured by combining spatial analysis with ES valuation. These results indicated that water yield, soil retention, and water purification presented varying degrees of increase from 1990 to 2020, with rates of 4.53%, 21.80% and 5.40%, respectively. The order of the mean WES trade-offs in the upstream, midstream, and downstream regions remained stable at the grid scale from 1990 to 2020, while there were important changes at the county scale. Climate change had a greater impact on WES trade-offs than LUCC, with climate change dominating 88.17% of the total area. The effect of climate change on WES trade-offs across areas was in the order of downstream > midstream > upstream, while the effect of LUCC was not obvious. The relative importance of drivers on WES trade-offs from 1990 to 2020 was dominated by climate dominance (71.50%), followed by LUCC to climate dominance (13.66%) and least by LUCC dominance (0.65%). This research emphasized the importance of LUCC and climate change on ES trade-offs in heavily disturbed areas, providing important guidance for multi-objective land management that sustainably provides ESs.
Evaluating the Uncertainties in Forest Canopy Height Measurements Using ICESat-2 Data
Authors: Rai Nitant , Ma Qin , Poudel Krishna P. , Himes Austin , Meng Qingmin
Published: May 2024

Forest ecosystems have been identified as major carbon stocks in terrestrial ecosystems; therefore, their monitoring is critical. Forests cover large areas, making it difficult to monitor and maintain up-to-date information. Advances in remote sensing technologies provide opportunities for detailed small-scale monitoring to global monitoring of forest resources. Airborne laser scanning (ALS) data can provide precise forest structure measurements, but mainly for small-scale forest monitoring due to its expensive cost and limited spatial and temporal coverage. Spaceborne lidar (light detection and ranging) can cover extensive spatial scales, but its suitability as a replacement for ALS measurements remains uncertain. There are still relatively few studies on the performance of spaceborne lidar to estimate forest attributes with sufficient accuracy and precision. Therefore, this study aimed at assessing the performance of spaceborne lidar ICESat-2 canopy height metrics and understanding their uncertainties and utilities by evaluating their agreements with ALS-derived canopy height metrics in Mississippi, United States. We assessed their agreements for different forest types, physiographic regions, a range of canopy cover, and diverse disturbance histories using equivalence tests. Results suggest that ICESat-2 canopy height metrics collected using strong beam mode at night have higher agreement with ALS-derived ones. ICESat-2 showed great potential for estimating canopy heights in evergreen forests with high canopy cover. This study contributes to the scientific community’s understanding of the capabilities and limitations of ICESat-2 to measure canopy heights at regional to global scales.

Consumption of fried foods is highly prevalent in the Western dietary pattern. Western diet has been unfavorably linked with high risk of developing cardiovascular diseases. Heart failure (HF) as a cardiovascular disease subtype is a growing global pandemic with high morbidity and mortality. However, the causal relationship between long-term fried food consumption and incident HF remains unclear. Our population-based study revealed that frequent fried food consumption is strongly associated with 15% higher risk of HF. The causal relationship may be ascribed to the dietary acrylamide exposure in fried foods. Further cross-sectional study evidenced that acrylamide exposure is associated with an increased risk of HF. Furthermore, we discover and demonstrate that chronic acrylamide exposure may induce HF in zebrafish and mice. Mechanistically, we reveal that acrylamide induces energy metabolism disturbance in heart due to the mitochondria dysfunction and metabolic remodeling. Moreover, acrylamide exposure induces myocardial apoptosis via inhibiting NOTCH1-phosphatidylinositol 3-kinase/AKT signaling. In addition, acrylamide exposure could affect heart development during early life stage, and the adverse effect of acrylamide exposure is a threat for next generation via epigenetic change evoked by DNA methyltransferase 1 (DNMT1). In this study, we reveal the adverse effects and underlying mechanism of fried foods and acrylamide as a typical food processing contaminant on HF from population-based observations to experimental validation. Collectively, these results both epidemiologically and mechanistically provide strong evidence to unravel the mechanism of acrylamide-triggered HF and highlight the significance of reducing fried food consumption for lower the risk of HF.
An Improvement on Likert Scale via Fuzzy Relation
Authors: Okediji Busayo Adeyege , Adekunle Abdullahi Ayomide
Published: May 2024

Relation is a mathematical concept that is often used in modeling relationships in physical and social sciences and the likes. The advent of fuzzy sets which model imprecision and uncertainties that occur in social animals necessitates the introduction of fuzzy relations. Besides, events and situations possess properties which are often contradictory such as good and bad, positive and negative, profit and loss and so on. We dug several literatures, particularly the analysis and hypothesis testing of several results from questionnaires, compared one of them with our newly proposed Likert scale which has fuzzy influence. The results of the two cases was analysed and presented with a bar chart, and it was clear that unlike the usual Likert scale that could be restricted from outliers, the one with fuzzy influence took care of uncertainties.
Formation of the media image of a political party in the regional information space (on the example of the Komi branch of the communist party)
Authors: Beshkarev A. A. , Pystina O. V.
Published: May 2024

The purpose of the article is to identify ways to create an image of a regional political party using the example of network media and social media of the Komi Republic for the period from 2020 to 2023. The scientific novelty of the work consists in a comprehensive analysis of regional network resources that form the image of the Communist Party in the Komi Republic, which has not yet been the subject of scientific understanding. As a result, it was determined that, depending on the type, audience and ideological orientation of the network resource, the image of the Communist party chosen for analysis appears in the regional media field in three variants: positive — on the social media pages of the regional branch of the Communist Party itself; mixed — in telegram channels representing the civic journalism of the region; predominantly negative — in the official media of Komi Republic.

Voluntary and forced collaboration of Soviet citizens with Nazi occupiers
Authors: Kulik S. V.
Published: May 2024

After the end of the Great Patriotic War, people who lived in the territory temporarily occupied by the enemy were forced to respond positively to the question of the enquiry about this discrediting fact. Not all of them were members of partisan detachments. At the same time, it should be recognized that the vast majority of them were not subjected to criminal prosecution. This means that bodies of the Soviet government realized that those citizens had no other opportunity to survive. However, some of Soviet citizens opt to collaborate with the enemy. They held various positions in the collaborationist administration, became village elders and policemen. The Soviet Resistance deservedly considered them enemies and waged a relentless fight against them.

Commenting and compiling medical literature in the Byzantine period of Late Antiquity and Early Middle Ages
Authors: Stanevich S. V. , Nazarova I. G.
Published: May 2024

The transmission of medical knowledge played an important role in the history of medicine. Historically, the first medical texts were created in ancient Greek and Latin. The article examines the ways in which medical knowledge recorded in primary sources, mainly the works of Hippocrates and Galen, was further spread in subsequent epochs and beyond the geographical boundaries of its origin, namely, commenting and compiling. These methods were used everywhere in Europe, Asia, and the Middle East, but the authors limit their consideration mainly to Byzantium. A brief overview of the development of medicine in Byzantium is given, and the history of the comprehension and transmission of medical knowledge through commenting and compiling is considered. The authors concern the role and significance of some outstanding Greek commentators and compilers of medical literature, whose names have been preserved in the history of medicine. The role of Byzantium as an important link in the global progress of medicine is substantiated.
Thematic variety of M.Shulgin's creativity
Authors: Kultysheva O. M. , Yakovinov M. V.
Published: May 2024

The article explores the themes characteristic of the work of the Khanty writer M.I.Shulgin (1940—2007). This study proceeds from the fact that the writer and his works are insufficiently studied in domestic literary criticism. Little attention is paid to the poetic works of M.Shulgin only in the regional curriculum. The main research methods are the analysis of scientific literature on the research topic, the cultural-historical method that studies the reflection of a cultural era in a work of art, hermeneutics aimed at interpreting the text and the method of system-holistic analysis of a literary work. As a result of the study, the following conclusion is drawn: the themes characteristic of M. Shulgin’s work mainly reflect the mythological and cosmological ideas of the Ob Ugrians, namely, the Khanty people. These are such themes as the themes of the motherland, native nature, ancestors. However, Shulgin, stating the irreversibility of the changes brought by modernity to the Khanty’s life, cultivates in his work such themes as the theme of labour, scientific and technological progress. A special place in Shulgin’s work is occupied by the children’s theme, which is also associated with the idea of the Khanty people that the upbringing of children should take place through familiarization with the people’s culture through fairy tales that reflect their mythological ideas.
