From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

Laser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Metasurface‐Enabled Single‐Shot Intensity‐and‐Phase‐Interrogation Surface‐Plasmon‐Resonance Microscopy

Laser &Photonics Reviews, EarlyView.
A metasurface‐enabled full‐Stokes polarimeter is integrated with phase‐interrogated surface plasmon resonance microscopy to enable single‐shot recovery of intensity and differential phase. The non‐interferometric platform supports quantitative refractive‐index and thickness mapping, wavelength‐resolved sensing, and dynamic multi‐channel monitoring ...

Multispectral Mid‐Infrared Imaging With Incoherent Light via Adiabatic Upconversion

Laser &Photonics Reviews, EarlyView.
We demonstrate room‐temperature broadband MIR imaging based on adiabatic frequency upconversion, driven by a Q‐switched pump laser and incoherent illumination. The small‐foot‐print system upconverts the spectral range to the visible domain, without scanning, thermal control and with spatial resolution below 20μm$20\mathrm{\mu}\mathrm{m}$.

Disease Duration Differentiates Freezing of Gait Response to Subthalamic and Nigral Stimulation for Parkinson's Disease in an Exploratory Multicenter Controlled Trial

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Freezing of gait (FoG) belongs to most pressing unmet symptoms in the treatment of Parkinson's disease. Objectives To explore whether combined subthalamic and nigral (STN + SNr) deep brain stimulation improves FoG compared with optimized STN stimulation alone; to identify clinical variables associated with therapeutic response ...

Design of two step deterministic interleaver for turbo codes

, 2007
The performance and design of a deterministic interleaver for short frame turbo codes is considered in this paper. The main characteristic of this class of deterministic interleaver is that their algebraic design selects the best permutation generator ...

Toward Inter‐Sonication Monitoring of Skull and Brain Temperatures in Transcranial MRgFUS Using a 3D Stack‐of‐Spirals Sequence

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an MRI approach for simultaneous skull and brain temperature monitoring between sonications in transcranial MR‐guided focused ultrasound (MRgFUS) surgeries. Methods A 3D stack‐of‐spirals dual‐echo ultra‐short TE (UTE) sequence incorporating fat suppression, spiral deblurring, trajectory measurement, and B1 correction was ...
