Stable propagation of pulsed beams in Kerr focusing media with modulated dispersion
, 2004 We propose the modulation of dispersion to prevent collapse of planar pulsed beams which propagate in Kerr-type self-focusing optical media. As a result, we find a new type of two-dimensional spatio-temporal solitons stabilized by dispersion management ...

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids
Molecular Oncology, EarlyView.This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

Compensating group delay distortion of signals based on engineered material dispersion
AIP Advances, 2017 Dispersion, which originates from the total frequency responses of materials, devices and transmission lines, makes envelope distortion of signals inevitable in transmission systems.

Photon lifetime in a cavity containing a slow-light medium
, 2011 We investigate experimentally the lifetime of the photons in a cavity containing a medium exhibiting strong positive dispersion. This intracavity positive dispersion is provided by a metastable helium gas at room temperature in the electromagnetically ...

Dispersion compensation using high-positive dispersive optical fibers
Chinese Optics Letters, 2017 The common and traditional method for dispersion compensation in optical domain is concatenating the transmit optical fiber by a compensating optical fiber having high-negative dispersion coefficient. In this paper, we take an opposite direction and show how an optical fiber with high-positive dispersion coefficient can also be used for dispersion ...

Molecular Oncology, EarlyView.Detection of extrachromosomal circular DNA (eccDNA) in plasma samples from EGFR‐mutated non‐small cell lung cancer patients. Plasma was collected before and during treatment with the EGFR‐tyrosine kinase inhibitor osimertinib. Plasma eccDNA was detected in all cancer samples, and the presence of the EGFR gene on eccDNA serves as a potential biomarker ...

Broad-Band Soft X-ray Polarimetry
, 2009 We developed an instrument design capable of measuring linear X-ray polarization over a broad-band using conventional spectroscopic optics. A set of multilayer-coated flats reflects the dispersed X-rays to the instrument detectors.

Dispersive perturbations of optical solitons
Physical Review E, 2001 The precise manner in which radiation disperses away from a soliton in an optical fiber is a topic attracting current attention. The purpose of this paper is to emphasize that there exists a well-developed formalism derived from inverse scattering theory, which has ready application to this problem for the case when the radiation in question forms part

Screening for lung cancer: A systematic review of overdiagnosis and its implications
Molecular Oncology, EarlyView.Low‐dose computed tomography (CT) screening for lung cancer may increase overdiagnosis compared to no screening, though the risk is likely low versus chest X‐ray. Our review of 8 trials (84 660 participants) shows added costs. Further research with strict adherence to modern nodule management strategies may help determine the extent to which ...

Very small beam-size measurement by a reflective synchrotron radiation interferometer
Physical Review Special Topics. Accelerators and Beams, 2006 A synchrotron radiation (SR) interferometer with Herschelian reflective optics has been developed for the measurement of beams of several μm in size. In a conventional refractive SR interferometer, the dispersion effect of the objective lens limits the ...
