Absolute Phase Retrieval Using One Coded Pattern and Geometric Constraints of Fringe Projection System

Applied Sciences, 2018
Fringe projection technologies have been widely used for three-dimensional (3D) shape measurement. One of the critical issues is absolute phase recovery, especially for measuring multiple isolated objects.

Phase transitions in paradigm shift models. [PDF]

PLoS ONE, 2013
Two general models for paradigm shifts, deterministic propagation model (DM) and stochastic propagation model (SM), are proposed to describe paradigm shifts and the adoption of new technological levels.

Reduced-Complexity QAM-Aided Space-Time Shift Keying

, 2011
A novel reduced-complexity near-optimal detection algorithm is proposed for enhancing the recent coherently-detected Space-Time Shift Keying (STSK) scheme employing arbitrary constellations, such as L-point Phase-Shift Keying (PSK) and Quadrature ...

Bone and Soft Tissue Neoplasms in Infants Versus Older Children: A Report From the Cancer in Young People in Canada Program

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Infant bone and soft tissue neoplasms present distinct clinical challenges and lack large‐scale data to inform treatment decisions. This study aims to characterize bone and soft tissue neoplasms in infants in Canada and to compare their outcomes with those of older pediatric patients.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Direct characterization of the spatial effective refractive index profile in Bragg gratings

, 2005
We propose a pulse response method to directly characterize the phase of the spatial index modulation, including the dc refractive index distribution (distributed phase shift), discrete phase, and chirp of fiber Bragg gratings (FBGs).

Reconfigurable multi-level phase shift keying encoder-decoder for all-optical networks [PDF]

, 2003
We demonstrate the application of a uniform Bragg grating as a dynamically reconfigurable phase encoder-decoder for optical systems. Precise discrete phase modulation between chips is obtained simply by heating segments along the grating with fine ...

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Scattering Matrix, Phase Shift, Spectral Shift and Trace Formula for One-dimensional Dissipative Schrödinger-type Operators

, 2007
The paper is devoted to Schrödinger operators with dissipative boundary conditions on bounded intervals. In the framework of the Lax-Phillips scattering theory the asymptotic behaviour of the phase shift is investigated in detail and its relation to the ...
