Unsteady Aerodynamic Characteristics of a High-Speed Train Induced by the Sudden Change of Windbreak Wall Structure: A Case Study of the Xinjiang Railway

Under strong winds, the effect of sudden windbreak transition (WT) on high-speed trains is severe, leading to a deterioration of train aerodynamics and sudden yawing motion of the car body. To address these problems, based on a high-speed t...

An improved Harris corner detection method for honeycomb structures

Structural defects and cell irregularity significantly impact the performance and safety of honeycomb structures. Thus, various image processing techniques have been employed to evaluate the cell shape and detect structural defects within t...

Determination of optimum segmentation parameter values for extracting building from remote sensing images

Lately, with progresses in remote sensing information techniques and the growingly and unprecedented uses of its uses, remote sensing became a science that cannot be dispensed with in most fields and ground object extraction has turned out ...

Estimation for Two-Dimensional Nonsymmetric Coherently Distributed Source in L-Shaped Arrays

We explore the estimation of a two-dimensional (2D) nonsymmetric coherently distributed (CD) source using L-shaped arrays. Compared with a symmetric source, the modeling and estimation of a nonsymmetric source are more practical. A nonsymme...

FROM BARCHAN TO DOMIC SHAPE: EVOLUTION OF A COASTAL SAND DUNE IN NORTHEASTERN BRAZIL BASED ON GPR SURVEY

ABSTRACT A sand dune located near São Bento do Norte and Caiçara do Norte towns (northern coastal region of Rio Grande do Norte state, Northeastern Brazil) is rapidly migrating toward urban areas. To understand the depositional processes (e...

MFEFNet: An Efficient Network for Infrared Small Target Detection With Multiview Feature Extraction and Multiscale Attention Fusion

Infrared small target detection (IRSTD) remains a core challenge in remote sensing, mainly due to low signal-to-noise ratios, small target sizes, background interference, and large-scale variations. Although existing methods have achieved p...

Water Tank Experiments on Stratified Flow over Double Mountain-Shaped Obstacles at High-Reynolds Number

In this article, we present an overview of the HyIV-CNRS-SecORo (Hydralab IV-CNRS-Secondary Orography and Rotors Experiments) laboratory experiments carried out in the CNRM (Centre National de Recherches Météorologiques) large stratified wa...

Temporal and Spatial Analysis of Coastal Landscape Patterns Using the GEE Cloud Platform and Landsat Time Series

Owing to the rapid urbanization combined with global climate change, dramatic land-use change in coastal watersheds is occurred, which, in turn, cause the evolution of landscape patterns and threaten the valuable but fragile ecosystem. The ...

Land and Atmosphere Precursors to Fuel Loading, Wildfire Ignition and Post‐Fire Recovery

Abstract Land surface‐atmosphere coupling and soil moisture memory are shown to combine into a distinct temporal pattern for wildfire incidents across the western United States. We investigate the dynamic interplay of observed soil moisture...

Green synthesis of silver nanoparticles using terrestrial fern (Gleichenia Pectinata (Willd.) C. Presl.): characterization and antimicrobial studies

Novel silver nanoparticles from Gleichenia Pectinata (Willd.) C. Presl. was synthesized. A combination of spectroscopic and microscopic techniques were utilized to characterize the newly synthesized Gleichenia Pectinata Silver Nanoparticles...

Multi-gene phylogeny and morphological characters reveal seven new species of Micropsalliota (Agaricales, Agaricaceae) from southern China, with an updated key for the species distributed in China

Species of Micropsalliota generally grow in the tropics and are characterised by small, slender basidiomes, brown basidiospores, and cheilocystidia that vary in shape with capitate or subcapitate apex, and pigmented pileipellis. Based on mo...

Completing the picture of field-grown cereal crops: a new method for detailed leaf surface models in wheat

Abstract Background The leaf angle distribution (LAD) is an important structural parameter of agricultural crops that influences light interception, radiation fluxes and consequently plant performance. Therefore, LAD and its parametrized fo...

A practical introduction to skeletons for the plant sciences

Before the availability of digital photography resulting from the invention of charged couple devices in 1969, the measurement of plant architecture was a manual process either on the plant itself or on traditional photographs. The introduc...

The root enrichment of bacteria is consistent across different stress-resistant plant species

Bacteria, inhabiting around and in plant roots, confer many beneficial traits to promote plant growth and health. The secretion of root exudates modulates the nutritional state of the rhizosphere and root area, further selecting specific ba...

Microbial Electrosynthesis Reshapes Energy Metabolism and Physiology in Clostridium ljungdahlii

ABSTRACT Microbial electrosynthesis (MES) enables a variety of microorganisms, particularly acetogens, to utilize electrical energy in the form of electrons to produce valuable compounds from CO2. In the closely related process of gas ferme...

Seasonal monopolization of small carrion by a scarab beetle in terra firme Amazonian rainforests

Abstract Small vertebrate carcasses represent an abundant resource in tropical rainforests, where scavengers play a key role in nutrient recycling, enhancing productivity in nutrient-poor habitats such as Amazonian terra firme forests. Howe...

The Effectiveness of Simultaneous Training of Various Executive Functions (Hot and Cool; Focused on Simultaneous Parent-Child Training) on Improving the Empathy of Children with Attention Deficit Hyperactivity Disorder (ADHD)

The present study aimed to effectiveness of simultaneous training of various executive functions (hot and cool; focused on simultaneous parent-child training) on improving the empathy of children with attention deficit hyperactivity disorde...

EXPLORING Z GENERATION ATTITUDES TOWARD VARIETIES OF ENGLISH(ES)

English, one of the most dominant languages, has undergone transformations and divergences that have created a variety of variations in different parts of the world. The fact is that English has more than 160 acknowledged variations of acce...

Complex Ways in Which Landscape Conditions and Risks Affect Human Attitudes Towards Wildlife

Negative interactions between humans and wildlife (i.e. those presenting risks to human security or private property) can trigger retaliation and potential human-wildlife conflict (HWC). The nature and strength of these human responses may ...
