Pediatric Blood &Cancer, EarlyView.ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment. The International Society of Pediatric Oncology Europe Neuroblastoma Group (SIOPEN) Radiology and Nuclear Medicine Specialty Committees ...

Time Delay Signature Extraction of Optical Time-Delay Chaos Systems From Short and Noisy Time Series
IEEE Photonics JournalThe optical chaos communication (OCC) can provide physical layer security for high-speed data transmission. In these OCC systems, the time delay signature (TDS) serves as a crucial encryption key.

Equivalence of Linear Time-Delay Systems [PDF]
IEEE Transactions on Automatic Control, 2011 The question of characterizing those time-delay systems which are equivalent (up to bicausal transformations) to a delay-free system is a natural and fundamental problem which has been raised since the early 1980s. Surprisingly this problem remains largely open despite that some partial answers have been provided.

Phase synchronization in time-delay systems [PDF]
Physical Review E, 2006 Though the notion of phase synchronization has been well studied in chaotic dynamical systems without delay, it has not been realized yet in chaotic time-delay systems exhibiting non-phase coherent hyperchaotic attractors. In this article we report the first identification of phase synchronization in coupled time-delay systems exhibiting hyperchaotic ...

Controllability Analysis of Linear Discrete Time Systems with Time Delay in State
Abstract and Applied Analysis, 2012 The controllability issues for linear discrete-time systems with delay in state are addressed. By introducing a new concept, the minimum controllability realization index (MinCRI), the characteristic of controllability is revealed.

Stability Analysis of Linear Time-Varying Delay Systems via a Novel Augmented Variable Approach
MathematicsThis paper investigates the stability issues of time-varying delay systems. Firstly, a novel augmented Lyapunov functional is constructed for a class of bounded time-varying delays by introducing new double integral terms.

Oscillations in First-Order, Continuous-Time Systems via Time-Delay Feedback
Complexity, 2018 A technique to generate (periodic or nonperiodic) oscillations systematically in first-order, continuous-time systems via a nonlinear function of the state, delayed by a certain time d, is proposed.

Inference of a time delay in stochastic systems
Physical Review ResearchTime delay is ubiquitous in many experimental and real-world situations. However, from measurable data it is often unclear whether time delay plays a significant role in the dynamics, and if it does, how long the time lag really is.

IEEE AccessIn real-world applications, time delays and uncertain nonlinearities are inevitable and impose significant challenges in modern control systems. The uncertainties commonly include nonlinear backlash-like hysteresis, external disturbances, parameter ...
