The provided unique overview of state-of-the-art systems, technologies, and methods positioning navigation purposes. Through fair comparison performance achieved each system, was able to identify most promising approaches pinpoint critical working conditions. In 2020, included 5 diverse off-site...
The rising incidence of Alzheimer's disease (AD) poses significant challenges to traditional diagnostic methods, which primarily rely on neuropsychological assessments and brain MRIs. advent deep learning in medical diagnosis opens new possibilities for early AD detection. In this study, we introduce retinal vessel segmentation methods based U-Net ad iterative registration Learning (ReIU), extract maps from OCT angiography (OCT-A) facilities. Our method achieved accuracies 79.1% the DRIVE...
In the Bonan area, lower fourth member of Shahejie Formation (Es4x) is buried beneath a sedimentary pile ranging from 2500 to 5000 m. Understanding impact diagenetic alterations on these deeply reservoirs crucial for effective hydrocarbon exploration and production. This study employs terminal fan sedimentation model, encompassing depositional environments such as feeder channels, distributary floodplains, basinal zones, provide insights into spatial distribution reservoir properties their...
On the basis of core observation and description, multi-scale microscopic analysis related reservoir physical property analysis, petrological characteristics, characteristics diagenetic Lower Jurassic Sangonghe Formation in central area Junggar Basin are systematically studied, evolution sequence is further established. The results show that studied interval has undergone three processes: compaction, cementation dissolution during its development after burial. mainly goes through two stages:...
Two-dimensional (2D) antiferromagnetic (AFM) semiconductors have garnered significant attention due to their promising applications in spintronics and intriguing magneto-optical performance. However, low Néel temperatures (TN) inadequate air stability constrain application. Here, we report the synthesis of a 2D semiconducting CuFeS2 (CFS) exhibiting AFM order. It features high TN (473.0 ± 0.4 K) remains stable for at least 2 weeks. The semiconductor characteristics are confirmed via...
Abstract Ambient sunlight‐driven photothermal green syngas production via reverse water‐gas shift (RWGS) reaction is important for carbon neutrality, which lacks efficient and inexpensive catalysts at low temperatures. This studydemonstrates that the scalable Fe 3 O 4 supported with K atoms modified Ag nanoparticles (AgK/Fe ) exhibits a RWGS CO rate of 1089 mmol g −1 h 300 °C 100% selectivity through dynamic structural reconstruction, surpassing all reported platinum‐based catalysts. In situ...
The potential of liposome electrokinetic chromatography (LEKC), which is applied to estimate compound penetration through the skin, was evaluated in this report. Quantitative retention-activity relationships (QRARs) were successfully constructed between skin permeability coefficient (log K(p)) and retention values k), as well some calculated molecular descriptors by stepwise regression method (R(2) = 0.902). Furthermore, developed vector compare similarity reported lipophilicity measuring...
As a powerful global registration method for point clouds, the 4-points congruent sets (4PCS) algorithm has been wildly used in 3D scene reconstruction field. In this paper, we propose an adaptive 4PCS (A4PCS), which aims to provide robustness rigid transformation two or more overlapping laser scans. The proposed only incorporates distance information of stereoscopic base set and fast mechanism extraction into 4PCS. To ensure accuracy when dealing with restrictive situations, such as clouds...
Pedestrian navigation systems could serve as a good supplement for other methods or extending into areas where are invalid. Due to the accumulation of inertial sensing errors, foot-mounted inertial-sensor-based pedestrian (PNSs) suffer from drift, especially heading drift. To mitigate considering complexity human motion and environment, we introduce novel hybrid framework that integrates foot-state classifier triggers zero-velocity update (ZUPT) algorithm, zero-angular-rate (ZARU) state...
Due to the errors arising from low-cost inertial measurement units, pedestrian dead-reckoning (PDR) systems suffer accumulative velocity and position errors. Previous works proved that zero-velocity update (ZUPT) method can effectively reduce of PDR system so positional be mitigated. The ZUPT algorithm is triggered by a stance phase-detection module generally adopts fixed threshold. However, fixed-threshold-based detector not robust enough may recognize phases accurately with dynamic gait...
