Chaos and Complexity of quantum motion

, 2007
The problem of characterizing complexity of quantum dynamics - in particular of locally interacting chains of quantum particles - will be reviewed and discussed from several different perspectives: (i) stability of motion against external perturbations ...

A Note on Local Polynomial Regression for Time Series in Banach Spaces

Journal of Time Series Analysis, EarlyView.
ABSTRACT This work extends local polynomial regression to Banach space‐valued time series for estimating smoothly varying means and their derivatives in non‐stationary data. The asymptotic properties of both the standard and bias‐reduced Jackknife estimators are analyzed under mild moment conditions, establishing their convergence rates.

A Vulnerability Lens for Intuitive‐Logic Scenarios

FUTURES &FORESIGHT SCIENCE, Volume 8, Issue 1, April 2026.
ABSTRACT Exploration of possibilities by means of intuitive logic is hampered by a large number of scenarios, which easily exceed the limits imposed by human bounded rationality. While many practitioners constrain their scenarios within a 2 × 2 $2\times 2$ matrix by design, more structured approaches point to rationales such as eliminating ...

Toward Psychometric Learning Analytics: Augmenting the Urnings Algorithm with Response Times

Journal of Educational Measurement, Volume 63, Issue 1, Spring 2026.
Abstract Adaptive learning systems (ALS) aim to tailor the educational material to match the student's needs, ultimately improving the learning outcomes. An ALS dynamically adjust the level of practice based on the student's ability; therefore, obtaining accurate ability estimates is crucial.

Cointegrating Polynomial Regressions With Power Law Trends

Journal of Time Series Analysis, Volume 47, Issue 2, Page 331-344, March 2026.
ABSTRACT The common practice in cointegrating polynomial regressions (CPRs) often confines nonlinearities in the variable of interest to stochastic trends, thereby overlooking the possibility that they may be caused by deterministic components. As an extension, we propose univariate and multivariate CPRs that incorporate power law deterministic trends.

Research on Three‐Dimensional Autonomous Obstacle Avoidance Path Planning Methods for UAVs

Transactions on Emerging Telecommunications Technologies, Volume 37, Issue 2, February 2026.
This study presents a three‐dimensional autonomous obstacle‐avoidance path planning method for unmanned aerial vehicles (UAVs) based on a deep reinforcement learning (DRL)‐enhanced Mayfly Algorithm. The traditional Mayfly Algorithm suffers from issues such as random initial population generation and slow convergence.

Beyond the cross‐section: Rethinking the intention–behaviour gap through a conceptual and methodological lens

British Journal of Health Psychology, Volume 31, Issue 1, February 2026.
Abstract Objectives The intention–behaviour gap (IBG) remains a persistent challenge in health psychology. While intentions are widely recognized as proximal determinants of behaviour, they frequently fail to translate into action. This conceptual review aims to critically evaluate dominant models of the IBG and propose a dynamic, multidimensional ...

A practical guide to characterising ecological coexistence

Biological Reviews, Volume 101, Issue 1, Page 195-220, February 2026.
ABSTRACT Coexistence is simultaneously one of the most fundamental concepts of ecology, and one of the most difficult to define. A particular challenge is that, despite a well‐developed body of research, several different schools of thought have developed over the past century, leading to multiple independent, and largely isolated, branches of ...

Changes in expectation impact multiple steps of the visual perceptual decision process in adults

Physiological Reports, Volume 14, Issue 3, February 2026.
Abstract Perceptual decision‐making processes, particularly in the context of eye movements and reaction times (RT), have been studied to better understand how the brain integrates and responds to sensory information. Recent models have decomposed the process into multiple intermediate steps, including detection, instruction processing, decision, and ...

Quantum Monte Carlo Simulation of Bipolaron Superconductivity in Extended Hubbard–Holstein models on Face‐Centered‐Cubic and Body‐Centered‐Cubic Lattices

Annalen der Physik, Volume 538, Issue 1, January 2026.
Numerically exact quantum Monte Carlo calculations of bipolaron properties are used to estimate transition temperatures (T*) for Hubbard–Holstein models on face‐centre cubic (FCC) and body‐centre cubic lattices. Repulsion (U/W) can make bipolarons lighter and raise T*. Lattice properties leading to 1st order hopping means that T* is much higher for the
