Urban tree species mapping is an important prerequisite to understanding the value of urban vegetation in ecological services. In this study, we explored potential bi-temporal WorldView-2 (WV2, acquired on 14 September 2012) and WorldView-3 images (WV3, 18 October 2014) for identifying five dominant with object-based Support Vector Machine (SVM) Random Forest (RF) methods. Two study areas Beijing, China, Capital Normal University (CNU) Beijing (BNU), representing typical environment, were...
This paper presents the design, simulation, and validation experiments of a passive (battery-free) wireless frequency doubling antenna sensor for strain crack sensing. Since length patch governs antenna's resonance frequency, bonded to structural surface can be used measure mechanical or propagation by interrogating shift due change. In comparison with previous approaches such as radio identification, scheme is proposed new signal modulation approach sensor. The easily distinguish...
This study focuses on the acoustic emission wave classification for sake of more accurate and comprehensive rail crack monitoring in field typically with complex cracking conditions, high-operational noise, mass data. There are mainly three types waves induced by operational impact, propagation, respectively. Synchrosqueezed wavelet transform was introduced to represent intrinsic characteristics clearly time–frequency domain, where different mechanisms were found show various patterns energy...
Abstract Background The response of organisms to nanoplastic exposure has gradually received the attention. Nevertheless, role neurons in and underlying mechanism are still largely unclear. We here examined neuronal JNK MAPK signaling low-dose polystyrene (100 nm) Caenorhabditis elegans . Results Exposure nanopolystyrene range μg/L could increase expression genes ( jkk - 1 , mek jnk ) encoding pathway. Meanwhile, RNAi knockdown any these induced a susceptibility toxicity. In neurons,...
Artificial intelligence is widely applied to estimate ground-level fine particulate matter (PM2.5) from satellite data by constructing the relationship between aerosol optical thickness (AOT) and surface PM2.5 concentration. However, size properties, such as mode fraction (FMF), are rarely considered in satellite-based modeling, especially machine learning models. This study investigated linear non-linear relationships AOT (fAOT) over five AERONET stations China (Beijing, Baotou, Taihu,...
Caenorhabditis elegans is useful for assessing biological effects of spaceflight and simulated microgravity. The molecular response organisms to microgravity still largely unclear. Mitochondrial unfolded protein (mt UPR) mediates a protective against toxicity from environmental exposure in nematodes. Using HSP-6 HSP-60 as markers mt UPR, we observed significant activation UPR exposed increase expression mediated In treated nematodes, mitochondria-localized ATP-binding cassette HAF-1...
A high-strength bolt connection is the key component of large-scale steel structures. Bolt loosening and preload loss during operation can reduce load-carrying capacity, safety, durability In order to detect damage in multi-bolt connections civil engineering structures, we proposed a identification method based on time-frequency diagrams convolutional neural network (CNN) using vi-bro-acoustic modulation (VAM) signals. Continuous wavelet transform was employed obtain VAM signals as features....
Aiming at the traffic dynamic shortest path allocation problem with triangular fuzzy numbers as attribute values, a model method based on number weights is proposed. The weighted distance optimization of number, ideal solution and negative established. weight value each obtained by solving optimizing. similarity difference between information determined longitudinally using idea deviation maximization, evaluation uncertainty scheme under different attributes described horizontally entropy...
The existing single-pulse search algorithms for fast radio bursts (FRBs) do not adequately consider the frequency bandpass pattern of pulse, rendering them incomplete relatively narrow-spectrum detection pulses. We present a new algorithm narrow-band pulses to update standard pipeline, Bandpass-Adaptive Single-pulse SEarch Toolkit (BASSET). BASSET employs time-frequency correlation analysis identify and remove noise involved by zero-detection band, thereby enhancing signal-to-noise ratio...
