Mitigation of Optical Background Noise in Light-Emitting Diode (LED) Optical Wireless Communication Systems

IEEE Photonics Journal, 2013
One challenge faced by the in-home light-emitting diode (LED) optical wireless communication is the optical noises. Here, we first experimentally characterize the effect of optical background noise to the performance of the LED optical wireless ...

Optical performance monitoring for OFDM using low bandwidth coherent receivers.

Optics Express, 2012
We propose using low bandwidth coherent receivers for distributed optical performance monitoring. We demonstrate optical signal-to-noise ratio (OSNR) monitoring of both 20-Gb/s single-polarization and 40-Gb/s polarization-multiplexed coherent optical ...

Digital Activity Markers in Chronic Inflammatory Demyelinating Polyneuropathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate the utility of smartwatch and smartphone‐based activity metrics for assessing disease severity and quality of life in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). Methods In the electronic monitoring of disease activity in patients with CIDP (EMDA‐CIDP) trial, we performed a prospective ...

Water system virus detection [PDF]

, 1978
The performance of a waste water reclamation system is monitored by introducing a non-pathogenic marker virus, bacteriophage F2, into the waste-water prior to treatment and, thereafter, testing the reclaimed water for the presence of the marker virus.

Targeting RAGE with Nanobodies for Molecular Imaging of Cancers and Alzheimer's Disease

Advanced Biology, EarlyView.
RAGE‐specific nanobodies were isolated via phage display and characterized by ELISA, cell ELISA, and SPR. In vivo imaging in renal carcinoma and Alzheimer's disease mouse models demonstrated that NbF8, the highest‐affinity clone, selectively targeted RAGE‐overexpressing tumors and brain tissues, highlighting its potential as a molecular imaging agent ...

Measurement of surface torsional strain distributions on rotary shaft using FBG optical fiber sensing

Nihon Kikai Gakkai ronbunshu, 2016
Structural health monitoring has been used to confirm the durability evaluation and safety of a structure in which long-term use is required. Because the transmission loss of the optical fiber sensor is extremely small, it can measure the present status ...

RhoA and Rac1 as Mechanotransduction Mediators in Colorectal Cancer

Advanced Biology, EarlyView.
Analysing RhoA and Rac1 protein levels in Colorectal cancer (CRC) samples under mechanical strain highlights their potential as diagnostic markers. Monitoring their activity could offer valuable insights into how cancer spreads, paving the way for new approaches to better understand and diagnose colorectal cancer.
