MIMO free-space optical communication employing subcarrier intensity modulation in atmospheric turbulence channels

, 2009
In this paper, we analyse the error performance of transmitter/receiver array free-space optical (FSO) communication system employing binary phase shift keying (BPSK) subcarrier intensity modulation (SIM) in clear but turbulent atmospheric channel ...

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

The Orbital Angular Momentum Encoding System With Radial Indices of Laguerre–Gaussian Beam

IEEE Photonics Journal, 2018
Orbital angular momentum (OAM) in optical vortices (OV) beams offers a new dimension of space mode because coaxially propagating OV beams with different azimuthal OAM states are mutually orthogonal.

Free-space optical communication employing subcarrier modulation and spatial diversity in atmospheric turbulence channel [PDF]

, 2008
An expression for the bit error rate of a multiple subcarrier intensity-modulated atmospheric optical communication system employing spatial diversity is derived. Spatial diversity is used to mitigate scintillation caused by atmospheric turbulence, which

Feasibility and Tolerability of Performing Portable MRI for Neurological Disorders in an Outpatient Neurology Clinic: A Prospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Accessing brain magnetic resonance imaging (MRI) can be challenging, especially for underserved patients, which may lead to disparities in neurological diagnosis. Method This mixed‐methods study enrolled adults with one of four neurological disorders: mild cognitive impairment or dementia of the Alzheimer type, multiple sclerosis ...

Optical Orbital Angular Momentum Shift-Keying Communication Using Direct Demodulation

IEEE Access, 2019
Orbital angular momentum (OAM) shift-keying (SK), which manifests as the rapid switching of OAM modes, is crucial but severely hampered for lacking effective demodulation techniques in OAM communication.
