Dispersive stabilization [PDF]

open access: yesBulletin of the London Mathematical Society, 2010
Ill posed linear and nonlinear initial value problems may be stabilized, that it converted to to well posed initial value problems, by the addition of purely nonscalar linear dispersive terms. This is a stability analog of the Turing instability. This idea applies to systems of quasilinear Schrödinger equations from nonlinear optics.

Channel Capacity of Wavelength Division Multiplexing-Based Brillouin Optical Time Domain Sensors

open access: yesIEEE Photonics Journal, 2018
We propose and demonstrate a novel WDM-based Brillouin optical time domain analysis (BOTDA) sensor using Brillouin loss configuration, and theoretically analyze channel capacity of WDM-based brillouin optical time domain reflectometry (BOTDR) and BOTDA ...

Biofilm dispersion [PDF]

open access: yesNature Reviews Microbiology, 2020
The formation of microbial biofilms enables single planktonic cells to assume a multicellular mode of growth. During dispersion, the final step of the biofilm life cycle, single cells egress from the biofilm to resume a planktonic lifestyle. As the planktonic state is considered to be more vulnerable to antimicrobial agents and immune responses ...

Tracer Dispersion in Rough Open Cracks [PDF]

open access: yes, 1998
Tracer dispersion is studied in an open crack where the two rough crack faces have been translated with respect to each other. The different dispersion regimes encountered in rough-wall Hele-Shaw cell are first introduced, and the geometric dispersion ...

Study on Shrinkage Cracking Morphology of Cement Mortar with Different Nanoclay Particles under Restraint

open access: yesBuildings, 2022
In this paper, different types and particle sizes of nanoclay (nano-metakaolin—NMK—and nano-attapulgite—NMA—clay) were selected to study the effect of nanoclay on the properties of cement-based cementitious materials.

Dispersion-managed soliton fiber laser with random dispersion, multiphoton absorption and gain dispersion

open access: yes, 2018
We address the generation and interaction of dispersion-managed dissipative solitons (DMDS) in a model of fiber lasers with the cubic-quintic nonlinearity, multiphoton absorption and gain dispersion.

Effect of MDI Actuation Timing on Inhalation Dosimetry in a Human Respiratory Tract Model

open access: yesPharmaceuticals, 2022
Accurate knowledge of the delivery of locally acting drug products, such as metered-dose inhaler (MDI) formulations, to large and small airways is essential to develop reliable in vitro/in vivo correlations (IVIVCs). However, challenges exist in modeling
