Clinical and biomarker trajectories in sporadic Alzheimer's disease
Introduction: Amyloid beta (Aβ) deposition was identified to precede tau pathology and neurodegeneration in familial Alzheimer's disease (AD). But the divergence between sporadic and familial AD limits the extension of these...

Research on Removing Image Noise and Distortion in Machine Dial Recognition
This study aims to address the issues of image noise and distortion in machine dial recognition via initial denoising. A wavelet local threshold denoising method that combines high-frequency wavelet coefficients with wavelet...
Localization Algorithm Based on a Spring Particle Model (LASPM) for Large-Scale Unmanned Aerial Vehicle Swarm (UAVs)
A new localization algorithm based on large scale unmanned aerial vehicle swarm (UAVs) is proposed in the paper. The localization algorithm is based on a spring particle model (LASPM). It simulates the dynamic process of...
Masks for COVID-19.
Sustainable solutions on fabricating and using a face mask to block the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread during this coronavirus pandemic of 2019 (COVID-19) are required as society is directed...

Towards a Text-World Approach to Translation and Its Pedagogical Implications
Lu Tian, Hui Wang
Jul 01, 2019
Although it is widely acknowledged that translation is a cognitive process, there is scarcely any study establishing connections between the text and mental representations and giving a systematic and comprehensive explanation...
Localized management of non-indigenous animal domesticates in Northwestern China during the Bronze Age.
The movements of ancient crop and animal domesticates across prehistoric Eurasia are well-documented in the archaeological record. What is less well understood are the precise mechanisms that farmers and herders employed to...

Attention Pyramid Networks for Object Detection With Semantic Information Fusion
Hui Hua, Jiahong Chen
Jan 01, 2024
Pyramid context information fusion has limitations in distinguishing background and important semantic information. The attention mechanism solves the limitations, but the detection effect for small target detection and occluded...
