On-Chip Ultra-Compact Hexagonal Boron Nitride Topological Ring-Resonator in V…

Ultra-compact topological ring-resonators with chirality are important devices for quantum optics. However, there are limited demonstrations of chiral resonators, especially in the visible region. …

Low-Frequency Optical Fiber Fabry-Perot Acoustic Sensor Based on All-Phase Cr…

A high-sensitivity low-frequency fiber-optic Fabry-Perot (F-P) acoustic sensing scheme was proposed based on optical cross-correlation (OCC). The finite element method (FEM) is used to analyze the …

Dual Band Active Nanostructured Core Fiber for Two-Color Fiber Laser Operation

We present the experimental verification of a new type of an active nanostructured fiber devoted to simultaneous laser emission at two wavelengths: 1040 nm and 1534 nm in the fundamental mode. The …

Instance-Level Relative Saliency Ranking With Graph Reasoning

Conventional salient object detection models cannot differentiate the importance of different salient objects. Recently, two works have been proposed to detect saliency ranking by assigning differe…

Towards Accurate and Compact Architectures via Neural Architecture Transformer

Designing effective architectures is one of the key factors behind the success of deep neural networks. Existing deep architectures are either manually designed or automatically searched by some Ne…

Graph Convolutional Module for Temporal Action Localization in Videos

Temporal action localization, which requires a machine to recognize the location as well as the category of action instances in videos, has long been researched in computer vision. The main challen…

Price Optimization, and Product Recommendations

Alibaba, which operates one of the world’s largest e-commerce platforms, designed a comprehensive omnichannel retail infrastructure that enables both online and offline ordering of products, rang…

Semi-Supervised Linear Regression

We study a regression problem where for some part of the data we observe both the label variable (Y) and the predictors (X), while for other part of the data only the predictors are given. Such a p…

Cold-formed tubular members and connections : structural behaviour and design

Dynamic Intra-Cell Repositioning in Free-Floating Bike-Sharing Systems Using …

In bike-sharing systems, the spatiotemporal imbalance of bike flows leads to shortages of bikes at some locations and overages at some others, depending on the time of the day, resulting in user di…
