Highly coherent lasers with spectral hyperpurity can further advance the fields of science and engineering. Especially, a light source with controllable frequency domain parameters can be adapted t…
Problem definition: Although in-kind donations contribute to charity’s triple bottom line (i.e., generating additional revenue for the charity, contributing to social welfare, and reducing enviro…
The Kerr microresonators have aroused widespread interests for their ultrahigh integration, compatible fabrication and ultralow energy consumption. Similar to the traditional mode-locked fiber lase…
We demonstrated the high energy 1.65 μm singular beam generation from a dissipative soliton resonance (DSR) all-fiber Raman laser experimentally. By utilizing advantages of the high nonlinearity a…
With distinct advantages in power over behavioral phenotypes, brain imaging traits have become emerging endophenotypes to dissect molecular contributions to behaviors and neuropsychiatric illnesses…
We leverage an exogenous shock—the crackdown on corrupt Chinese officials beginning in 2012—and examine how the allocation of research subsidies and innovative outcomes were affected. We argue …
This paper is concerned with lq (0 < q < 1 ) -norm regularized minimization problems with a twice continuously differentiable loss function. For this class of nonconvex and nonsmooth composite prob…
Helical-core fibers have been widely utilized for various applications such as orbital angular momentum manipulation, optical filtering, and sensing. In this work, we demonstrate the sensitivity en…
Visible light communication (VLC), as an interdisciplinary paradigm, spans various technologies from basic device sciences to system engineering. Micro-size light-emitting diodes (micro-LEDs), beca…
Global Fréchet regression is an extension of linear regression to cover more general types of responses, such as distributions, networks, and manifolds, which are becoming more prevalent. In such …
