We present the design and fabrication of a 4 × 1 fiber combiner with low brightness loss. The effective area ratio (AR) of light transmission was first introduced to estimate the brightness loss. …
Object detection has recently experienced substantial progress. Yet, the widely adopted horizontal bounding box representation is not appropriate for ubiquitous oriented objects such as objects in …
Colloidal nanoplatelets (NPLs) are a kind of two-dimensional nano-material with an atomically flat surface, leading to an ultra-narrow emission linewidth of 8~12 nm. In this article, we fabricated …
Massive and diverse data is crucial to train a general deep learning model, while the data collection for model training is difficult, especially training on sensitive data (e.g., medical data and …
Generative adversarial networks (GANs) have been effective for learning generative models for real-world data. However, accompanied with the generative tasks becoming more and more challenging, exi…
