Effects of misalignments in the optical vortex transformation performed by holograms with embedded phase singularity

, 2010
Spatial characteristics of diffracted beams produced by a "fork" hologram from an incident circular Laguerre-Gaussian beam whose axis differ from the hologram optical axis are studied theoretically.

Combining chromosomal arm status and significantly aberrant genomic locations reveals new cancer subtypes [PDF]

, 2008
Many types of tumors exhibit chromosomal losses or gains, as well as local amplifications and deletions. Within any given tumor type, sample specific amplifications and deletionsare also observed.

Memory‐Reduced Convolutional Neural Network for Fast Phase Hologram Generation

Advanced Intelligent Systems, EarlyView.
This article reports a lightweight convolutional neural network framework using INT8 quantization to efficiently generate 3D computer‐generated holograms from a single 2D image. The quantized model reduces memory usage and computational cost, accelerates inference speed, and maintains high output quality, enabling real‐time holographic display on low ...

CGH for Indoor Visible Light Communication System

IEEE Access, 2017
In this paper, we propose, design, and evaluate two indoor visible light communication (VLC) systems based on computer generated holograms (CGHs); a simple static CGH-VLC system and an adaptive CGH-VLC system. Each transmitter is followed by the CGH, and

Postoperative complicated peripheral cortical cataract after ultrasound cycloplasty: a case report

BMC Ophthalmology, 2021
Background Ultrasound cycloplasty (UCP) is a non-invasive procedure for glaucoma treatment. Using high-intensity focused ultrasound to work on the ciliary body, the generation of aqueous humor can be reduced and the drainage of aqueous humor through the ...

Holography in CGHS ̂ $$ \hat{\textrm{CGHS}} $$ supergravity

Journal of High Energy Physics, 2023
Abstract We study holographic aspects of 2D dilaton-supergravity in flat space-time using gauge theoretic BF formulation. The asymptotic symmetries in Bondi gauge and at finite temperature span a supersymmetric extension of the warped Virasoro algebra at level zero.

The revision of baphetids from the Middle Pennsylvanian of the Czech Republic: Morphology, ontogeny, palaeoecology, and the reassessment of the phylogeny of Baphetoidea

The Anatomical Record, EarlyView.
Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...
