In this demonstration, we first demonstrate a real-time phosphor-LED visible light communication (VLC) system with 37 Mbit/s total throughput under a 1.5 m free space transmission length. The transmitter and receiver modules are compact size. Utilizing our proposed pre-equalization technology, the ~1 MHz bandwidth of phosphor LED could be extended to ~12(More)
The sub-thalamic nucleus (STN) is relevant to the preparation of movement ignition but its role in movement termination is uncertain. Fourteen patients with Parkinson's disease (PD) received local field potentials (LFPs) recording at the left STN on the fourth day after deep brain stimulation surgery. They performed phasic and tonic movements of the right(More)
This paper is concerned with a mathematical model for numerical simulation of 2D flood waves due to complete or partial dam-break. The governing water equations are solved by a implicit bidiagonal numerical scheme, based on the MacCormack's predictor-corrector technique. The mathematical model is used to numerically compute the water surface from(More)
Molecular trafficking within cells, tissues and engineered three-dimensional multicellular models is critical to the understanding of the development and treatment of various diseases including cancer. However, current tracking methods are either confined to two dimensions or limited to an interrogation depth of ∼15 μm. Here we present a three-dimensional(More)
In this study, we describe the modified quad-quaternion MUSIC (QQ-MUSIC) for two-dimensional direction finding and signal polarization estimation with electromagnetic vector sensor arrays. Firstly, a detailed analysis of the regular QQ-Model, based on the framework of quad-quaternion, is presented to clarify the exact reason why the regular QQ-MUSIC cannot(More)
In this work, we propose and investigate a 115 Gbit/s (4 Â 28.75 Gbit/s) downstream and 10 Gbit/s upstream time-and wavelength-division-multiplexing passive optical network (TWDM-PON) together with 11.25 Gbit/s wireless broadcasting signal using multi-band orthogonal-frequency-division-multiplexing (OFDM) modulation within 10 GHz bandwidth. Here, to(More)
NanoCluster Beacons (NCBs), which use few-atom DNA-templated silver clusters as reporters, are a type of activatable molecular probes that are low-cost and easy to prepare. While NCBs provide a high fluorescence enhancement ratio upon activation, their activation colors are currently limited. Here we report a simple method to design NCBs with complementary(More)
