Abstract:
... Heavy-duty diesel trucks (HDDTs) cause serious pollution to urban and regional environment. Understanding the spatiotemporal pattern of pollution emissions and its impact factors is the basis for implementing emission reduction measures. However, since the multiscale emission inventory of HDDTs is not currently established, multiscale analysis of these issues is still lacking. Therefore, this stud ...

Abstract:
... Microplastic pollution is an issue of major environmental concern worldwide. Land-use type may affect the abundance, polymer types, and distribution characteristics of soil microplastics but their distribution remains unknown on the coastal plain of east China. Here, the abundance of microplastics in farmland (FL), plantation (P), and orchard/secondary forest (OSF) soils was determined on the east ...

Abstract:
... As a public service facility that provides relief, resettlement, and evacuation services to disaster-affected people, emergency shelters play a vital role in helping people cope with disaster events. The measurement of spatial accessibility of existing emergency shelters is a key task in improving emergency shelter services and minimizing property losses and deaths. In this study, considering the ...

Abstract:
... We studied hippocampal variability in relation to the multiyear population density cycle and the action of density-dependent autoregulatory mechanisms associated with behavior. A study of field collections of the morphological material of bank voles (Clethrionomys glareolus, Rodentia) revealed annual variability in the hippocampal size against changes in the population density. The absolute and re ...

Abstract:
... An integrated assessment of the status of populations of Neottia ovata (L.) Bluff & Fingerh. (Orchidaceae Juss.) based on population characteristics is given: population quality, generativity index, renewability index, population density, vitality, and ontogenetic types of populations. It is established that the ontogenetic structure of coenopopulations of N. ovata is normal, incomplete, and left- ...

Abstract:
... With the rapid development of China’s social economy, the scale of land transfer has also increased, which has led to a new pattern of urban land space. This article uses global regression of ordinary least squares (OLS), spatial lag model (SLM), spatial error regression model (SEM) and local regression of geographically weighted regression model (GWR), and multi-scale geographically weighted regr ...

Abstract:
... Resistant crop varieties can usually decrease the population density of insect pests; however, they can also easily cause the occurrence of highly virulent pest populations when repeatedly grown. Whether herbivorous insects feeding intermittently on a susceptible variety affects their subsequent virulence has rarely been investigated. In this paper, we examined the variations in the virulence of t ...

Abstract:
... Localization is one of the main critical factors that influence the value creation process and performance of a business. Choosing a location to start a business often influences the consequent access to a series of resources and services essential to its development, becoming a key element for its survival. This is even more evident in mountain areas, which are conditioned by key factors such as ...

Abstract:
... Road traffic is an important contributor to CO₂ emissions. Previous studies lack enough spatiotemporal resolution in emission calculation at the road level and ignore the impact of the built environment on road traffic emissions. Therefore, this study develops a bottom-up methodology based on the traffic trajectory data to analyze the CO₂ emission characteristics of road traffic with a high level ...

Abstract:
... This paper examines the impact of earthquake risk on the lending behavior of local Chinese banks. The results show that when facing earthquake risk, banks will adjust their lending behavior, including decreasing the amount of loans and mortgage loans and increasing credit loans and loan loss provision, but the effect only exists for banks without inter-provincial branches or that are located in ci ...

Abstract:
... Average population density has been a traditional urban sprawl indicator, but it is insufficient to encapsulate its detrimental impacts. We demonstrate that cities of identical average population density may be subject to very different levels of car dependency, CO₂ emissions and public budget deficits. To capture this, we shed light into the properties of two “density-allocation” indicators: the ...

Abstract:
... The city plays a crucial role in CO₂ emissions reduction, and exploring the accounting methods of city-level CO₂ emissions is important for formulating effective emission reduction policies. Although previous studies have verified a linear relationship between nighttime light data (NTL) and CO₂ emissions at the provincial level, the consistent fitting coefficient adopted by cities ignored the soci ...

Abstract:
... We present a detailed mechanistic study of the PD process, focused on the nucleation and growth dynamics of silver particles on fingermarks deposited on a paper surface, from macroscopic (whole fingermark) and microscopic (particle level) perspectives. Conceptually, we separate the outcomes into aspects that precede exposure of the exhibit (relating to the reagent formulation), that relate to the ...

Abstract:
... The world's population is shifting to the cities, and consequently, cities worldwide are growing in number and in size. Cities are complex systems, making it extremely difficult to build and run cities in a way that all the elements of the system operate in harmony. Recently a concept of urbanome, the genome of the city was proposed to address this complexity. Here we first explore this concept an ...

Abstract:
... The distribution of >100-µm charcoal particles, which may be traces of forest fires in the surrounding area, has been analyzed in the bottom sediments of lakes Cheko and Zapovednoe in the south of the Evenk district (Krasnoyarsk krai). The background content of charcoal particles in sediments of about 1500 years old is no less than in recent sediments. This is evidence that the intensity of fires ...

Abstract:
... Range expansion is the spatial spread of a population into previously unoccupied regions. Understanding range expansion is important for the study and successful management of ecosystems, with applications ranging from controlling bacterial biofilm formation in industrial and medical environments to large scale conservation programmes for species undergoing climate‐change induced habitat disruptio ...

Abstract:
... The methane (CH₄) emissions from urban sources are increasing, and they depend on the processes and technologies applied in each one. Thus, studying them individually to quantify their emissions and understand their behavior to design CH₄ mitigation strategies is meaningful. Although many studies have been carried out in different cities worldwide, the complex methodologies and technologies applie ...

Abstract:
... Cooking is an important source of organic aerosols (OA), particularly in urban areas, but it has not been explicitly included in current emission inventories in China. This study estimated the organic aerosol emissions from cooking during winter over the Pearl River Delta (PRD) region, China. Using the retrieved hourly cooking organic aerosol (COA) concentrations at two sites in Hong Kong and Guan ...

Although investigators are using data sources to describe the visual characteristics of streets, few researchers have linked human perceptions of the street environment with human activity density. This study proposes a conceptualized analytical framework that explains the relationship between human activity density and the visual characteristics of the streetscape.
