Abstract:
The manipulation of light via nanoengineered surfaces has excited the optical community in the past few decades. Among the many applications enabled by nanophotonic devices, sensing has stood out due to their capability of identifying miniscule refractive index changes. In particular, when free-space propagating light effectively couples into subwavelength volumes created by nanostructures, the strongly-localized near-fields can enhance light’s interaction with matter at the nanoscale. As a result, nanophotonic sensors can non-destructively detect chemical species in real-time without the need

Vascular gene therapy is a potential promising treatment for atherosclerotic disease. Imaging of vascular gene therapy is essential for the assessment of the success of the therapeutic strategy. Several imaging techniques, including MRI, ultrasound, and optical imaging, have been evaluated to monitor, enhance, and track vascular gene delivery, transfection/transduction, and expression. This review summarizes the current status of applying these techniques in the imaging of vascular gene therapy.

Optical fiber communication coding and modulation techniques play a key role in high-speed and high-capacity transmission but are still limited by problems such as signal attenuation, nonlinear effects and increasing bit error rate. In order to optimize the performance of optical communication systems, this study draws on the biomechanical signal conduction mechanism to construct an optical fiber modulation scheme that integrates pulse time coding, adaptive modulation and redundancy coding.

Random sampling is an efficient method dealing with constrained optimization problems. In computational geometry, it has been applied, through Clarkson's algorithm [10], to solve a general class of problems called violator spaces. In machine learning, TSVM is a learning method used when only a small fraction of labeled data is available, which implies solving a non convex optimization problem. Several approximation methods have been proposed to solve it, but they usually find suboptimal solutions. Global optimal solution may be obtained using exact techniques, costing an exponential time compl

Abstract:
The rod photoreceptor of the retina is a quantum detector whose physiological function in physically unfavorable conditions (body temperature, salt solution) is made possible by specific protein interactions. Photon energy is stored by the receptor protein rhodopsin (R) in a structurally transformed state. Activated R interacts with transducin (a G-protein or guanine nucleotide binding protein). This catalyses binding to G of energy-rich nucleotide which in turn releases G in an activated form. Absorption of one photon leads to the activation of 1000 G in 1 s.
