Spectral continuation study of the temporally periodic solitons of the damped-driven nonlinear Schrödinger equations [PDF]

open access: yes, 2012
Includes abstract.Includes bibliographical references.In this thesis we develop and employ a spectral continuation algorithm, implemented in AUTO, to study the temporally periodic spatially localised soliton solutions of the driven, damped nonlinear ...

Nordgren PINNs to VQE: Advancing Hydraulic Fracturing Simulations in Shale Reservoirs

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study advances hydraulic fracturing simulations in shale reservoirs using two computational paradigms, Physics‐Informed Neural Networks (PINNs) and the Variational Quantum Eigensolver (VQE). PINNs were employed to solve Nordgren's equation, which governs fracture width evolution, by embedding physical laws into the neural network ...

Approximate Reachability for Feedback Linearizable Systems

open access: yesOptimal Control Applications and Methods, EarlyView.
The backwards reachable set for a dynamical system is the set of states for which there exists a constraint admissible trajectory that reaches a given terminal set. Conventional grid‐based approaches for computing these sets are intractable for many applications.

Feedback Linearisation with State Constraints

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Feedback Linearisation (FBL) is a widely used technique that applies feedback laws to transform input‐affine nonlinear control systems into linear control systems, allowing for the use of linear controller design methods such as pole placement.

Responsive nitric oxide‐releasing antibacterial materials for biofilm‐associated infections: Mechanisms, design strategies, and applications

open access: yesResponsive Materials, EarlyView.
This review summarizes the recent progress in responsive NO‐releasing materials and their applications in biofilm‐associated infectious diseases. The design principles and response mechanisms are given to provide inspiration toward the future development of multi‐responsive NO‐releasing materials.

High-order unconditionally stable FC-AD solvers for general smooth domains II. Elliptic, parabolic and hyperbolic PDEs; theoretical considerations [PDF]

open access: yes, 2010
A new PDE solver was introduced recently, in Part I of this two-paper sequence, on the basis of two main concepts: the well-known Alternating Direction Implicit (ADI) approach, on one hand, and a certain “Fourier Continuation” (FC) method for the ...

Treatment Patterns and Pathways of Systemic Drug Therapy in Patients With Plaque, Erythrodermic, and Generalized Pustular Psoriasis: A Retrospective Cohort Study in Japan

open access: yesThe Journal of Dermatology, EarlyView.
ABSTRACT Systemic psoriasis treatment options have rapidly expanded in Japan, including the approval of tyrosine kinase 2 and interleukin‐36 receptor inhibitors in 2022. However, contemporary real‐world treatment patterns across plaque, erythrodermic, and generalized pustular psoriasis remain incompletely characterized.

Stability and regularity in nonlinear partial differential equations [PDF]

open access: yes
This thesis is concerned with the stabilizing and regularizing effects caused by the dissipation of entropy in two quite different contexts: (1) the kinetic theory of collisional plasmas and (2) inviscid, compressible fluid mechanics.

Integrating infection intensity and aggregation into the dynamics of pathogens with within‐host replication

open access: yesJournal of Animal Ecology, EarlyView.
We bridge micro‐ and macroparasite theory with a model tracking pathogen load heterogeneity. By incorporating load‐dependent mortality and within‐host pathogen growth, we show how pathogen load aggregation alters disease prevalence, host suppression effects, and virulence evolution, providing insights for managing complex infectious disease like ...
