Phase shift in experimental trajectory scaling functions

open access: yes, 1993
For one dimensional maps the trajectory scaling functions is invariant under coordinate transformations and can be used to compute any ergodic average.

A Two-Level Optimization Method for Hypersonic Periodic Cruise Trajectory

open access: yesInternational Journal of Aerospace Engineering, 2021
Periodic cruise has the potential to improve the fuel-saving efficiency of hypersonic cruise vehicle but is difficult to optimize. In this paper, a two-level optimization method for the trajectory of periodic cruise is proposed.

Generalized isocline method of plotting phase-plane trajectories [PDF]

open access: yesIEEE Transactions on Automatic Control, 1965
By considering simultaneously the N-x (or the N-\dot{x} ), where N=d\dot{x}/dx and the \dot{x}-x planes, second order non-linear autonomous systems (not easily amendable to the existing methods) described by the differential equation \ddot{x}=F(x, \dot{x}) can be studied.

Anomalous Indoor Human Trajectory Detection Based on the Transformer Encoder and Self-Organizing Map

open access: yesIEEE Access, 2023
Anomalous human trajectory detection is a critical task in security surveillance in working areas. To identify anomalous human trajectories, understanding features of their movement plays an important role.

Experimental Observation of a Topological Phase in the Maximally Entangled State of a Pair of Qubits

open access: yes, 2007
Quantum mechanical phase factors can be related to dynamical effects or to the geometrical properties of a trajectory in a given space - either parameter space or Hilbert space.

Non-Equilibrium Phase Transition in an Atomistic Glassformer: the Connection to Thermodynamics [PDF]

open access: yes, 2017
Tackling the low-temperature fate of supercooled liquids is challenging due to the immense timescales involved, which prevent equilibration and lead to the operational glass transition.

Predicting Chronicity in Children and Adolescents With Newly Diagnosed Immune Thrombocytopenia at the Timepoint of Diagnosis Using Machine Learning‐Based Approaches

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...
