We experimentally demonstrate to drive domain growth in lithium niobate crystal by using a focused infrared femtosecond laser without relative displacement or any additional …
Nowadays, one of the most common approaches for video watermarking is to use singular value decomposition in the discrete wavelet transform domain. In our prior work, we formulated …
Richards’ equation is a classical differential equation describing water transport in unsaturated porous media, in which the moisture content and the soil matrix depend on the …
This paper introduces a simple but powerful segmentation algorithm for 3D meshes. Our algorithm consists of two stages: over-segmentation and region fusion. In the first stage, …
Polyphonic sound event detection aims to detect the types of sound events that occur in given audio clips, and their onset and offset times, in which multiple sound events may …
In underwater acoustic communications, a hydrophone array is often used to receive the underwater acoustic signals to improve the gain of the received signal. The direction of …

Characterization of nonlocality is an open problem in physics and engineering. This paper conducts a detailed investigation on two nonlocal models, namely, the fractional …
声音事件检测是目前计算机听觉领域中的重要问题，而多声音事件检测是其中一个极具挑战性的研究热点。基于最新提出的非迭代的自注意力路由方法和胶囊网络，本文提出了一种基于自注意力路由的多路径胶囊网络模型，将其用于多声音事件检测。由于自注意力路由方法是非迭代且高度并行的，大大加快了模型的训练速度；多路径基础胶囊层使用不同大小的非对称卷积核，不仅使模型能获得不同分辨率的 …
自然资源部第一海洋研究所地球系统模式FIO-ESM是自主研发的、以耦合海浪模式为特色的地球系统模式，包括物理气候模式和全球碳循环模式。该模式从第一代版本FIO-ESM v1.0发展到第二代版本FIO-ESM v2.0，其物理气候模式和全球碳循环模式都取得了改进与提升。FIO-ESM v2.0全球碳循环模式的海洋碳循环模式由v1.0的营养盐驱动模型升级为 …
