Dynamics of Fractional Vortex Beams at Fraunhofer Diffraction Zone
Photonics, 2022 Fractional vortex beams (FVBs) possess unique topological properties that are manifested in the vortex distribution. However, there are still discrepancies in the value of the vortex strength of FVBs at the far field.

Image reconstruction in fluorescence molecular tomography with sparsity-initialized maximum-likelihood expectation maximization [PDF]
, 2018 We present a reconstruction method involving maximum-likelihood expectation maximization (MLEM) to model Poisson noise as applied to fluorescence molecular tomography (FMT). MLEM is initialized with the output from a sparse reconstruction-based approach,

Survey of Crystal Singular Optics [PDF]
, 2019 Among the various directions modern optics has taken to develop applications for optical nano-tweezer and nano-manipulator designs, one that stands out is the use of singular optics approaches to anisotropic media. It is well known that singular optics deals with light beams that support wavefront edge dislocations and optical vortices (screw ...

Generalized Antiorthotomics of (n, m)-Cusp Curves
MathematicsIn optics, light rays emitted from a light source form a wavefront (orthotomic) upon reflection by a mirror. The mirror is referred to as an antiorthotomic of the orthotomic.

Time-Energy Costs of Quantum Measurements [PDF]
, 2014 Time and energy of quantum processes are a tradeoff against each other. We propose to ascribe to any given quantum process a time-energy cost to quantify how much computation it performs.

Multidimensional Profiling of MRI‐Negative Temporal Lobe Epilepsy Uncovers Distinct Phenotypes
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Although hippocampal sclerosis (TLE‐HS) represents the most frequent cause of temporal lobe epilepsy (TLE), up to 30% of patients show no lesion on visual MRI inspection (TLE‐MRIneg). These cases pose diagnostic and therapeutic challenges and are underrepresented in surgical series.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Cognitive impairment is a common non‐motor symptom in Multiple Sclerosis (MS), negatively affecting autonomy and Quality of Life (QoL). Innovative rehabilitation strategies, such as semi‐immersive virtual reality (VR) and computerized cognitive training (CCT), may offer advantages over traditional cognitive rehabilitation (TCR ...
