The Range–Doppler (R-D) model is extensively employed for the geometric processing of Synthetic Aperture Radar (SAR) images. Refining sensor motion state and imaging parameters most common method achieving high-precision using R-D model, comprising a process that involves numerous complex computations. In this study, we introduce novel approach to improve positioning accuracy implementing low-order polynomial compensate original errors without altering initial parameters. We also design...

Knowledge transfer in engineering design activity involves effectively applying prior practical experience novel contexts. While related works fostering knowledge focus on educational practices and generalisation, recent advancements enable us to analyze its complex cognitive processes using neuroimaging technology. This paper proposes a multimodal approach for facilitating design, utilising functional near-infrared spectroscopy (fNIRS) eye-tracking technologies based neurocognitive...

The leaf microbiota plays a key role in plant development, but detailed mechanism of microbe-plant relationships remains elusive. Many genome-wide association studies (GWAS) have begun to map microbes, few systematically characterized the genetics how microbes act and interact. Previously, we integrated behavioral ecology game theory define four types microbial interactions – mutualism, antagonism, aggression, altruism, community assembly. Here, apply network mapping identify specific genes...

The booming Internet technology and media have generated large sets of social data, with which the sensing analyses based on users' reviews become a research hotspot been increasingly applied in study urban park usage perception. However, most existing studies adopt single model for text data processing. To fill this gap, aims to compare analysis methods assess their advantages, disadvantages applicability perception research. Lexicon-based classification (lexicon model) LDA (Latent...

Wireless resource virtualization scheme has been proposed to satisfy the quality of service (QoS) requirement multi-service traffic flows on multi-dimensional resources. However, it is a challenge design an appropriate virtual allocation strategy for meet delay demand multi-service. In this paper, we study method in TDD-F-OFDM system with MU-MIMO and formulate optimization problem as cross-layer problem. Then, develop effective dynamic algorithm iterative dual update targets Media Access...

Water microorganisms including many rare taxa and few abundant which have distinct contribution to community dynamics, are crucial the wetland ecosystem functions. In this study, we comprehensively investigated diversity patterns assembly processes of strengthen our understanding function in a system. The results showed that TN NH 4 + -N were most significant factors affecting structure wetland. FAPROTAX metabolic predication analysis revealed functions associated with nitrogen removal...

Purpose. The study explored how Feifei, a 3-year-old trilingual girl living in England, uses touchscreens across her multiple languages (English, Mandarin, and Bahasa Indonesia), exploring social interactions interact with touchscreen use. Design/methodology/approach. research adopts case approach, using mediagrams, supported by family interviews parent-recorded interviews, expanding conceptualisations of funds identity the analysis. Findings. mediagrams supporting relate Feifei's...

Refining sensor motion state and imaging parameters most common method achieving high-precision using R–D model, comprising a process that involves numerous complex computations. In order to reduce specialization complexity parameter optimization in classic we introduced novel approach called ICRD (image compensation-based range–Doppler) improve positioning accuracy...

As an important part of the urban ecosystem, value green spaces (GS) has become increasingly prominent. However, interaction effect GS characteristics are still not clear enough. This study explores premium different types on housing prices (HP) in Beijing. The results show that all have a significant impact HP, among which there obvious distance and area thresholds for park GS. range municipal parks is within 2000 m and, closer to community, higher value. In contrast, community-level only...

We consider the weighted low rank approximation of positive semidefinite Hankel matrix problem arising in signal processing. By using Vandermonde representation, we firstly transform into an unconstrained optimization and then use nonlinear conjugate gradient algorithm with Armijo line search to solve equivalent problem. Numerical examples illustrate that new method is feasible effective.

Classroom discourse can affect students’ classroom involvement and enthusiasm. discourse, one of the basic contents teaching in colleges universities, is divided into student system, teacher student-teacher system. Strengthening all three bring something unexpected to teaching. Based on this, this article focuses things: role teaching, impact involvement, how have no improvement quality.

The science-practice gap has recently been discussed as a critical challenge restricting sustainable growth and development in all facets of our society, including explorations Recreation Ecosystem Services (RES). To better explore how well the scientific study RES its application are connected, this paper aims to synthesize empirical evidence based on an in-depth systematic literature review. We found that studies have not effectively transformed into decision-making long-term planning...

Abstract Background: Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumor in adults. The predictive role of SH2D4A has been shown to be closely related various cancers progression,but there no comprehensive analysis clinical significance glioblastoma. Hence, this study aimed explore relationship between prognosis GBM expression. Methods: expression was analyzed using TIMER2.0 GEPIA, validated by qRT-PCR experiments. CGGA database differential glioma evaluated...
