Calculation of a Dynamical Substitute for the Real Earth–Moon System Based on Hamiltonian Analysis

The Astrophysical Journal
The Earth–Moon libration points no longer exhibit the dynamical characteristics of “equilibrium points” due to perturbation effects when applying the ephemeris model. By decoupling the forced motions within the ephemeris model and computing the dynamical

Finite-time Lyapunov exponents and metabolic control coefficients for threshold detection of stimulus–response curves

Journal of Biological Dynamics, 2016
In biochemical networks transient dynamics plays a fundamental role, since the activation of signalling pathways is determined by thresholds encountered during the transition from an initial state (e.g. an initial concentration of a certain protein) to a

On asymptotic output stability for delay differential systems [PDF]

Известия высших учебных заведений: Прикладная нелинейная динамика
The purpose of this study is to obtain sufficient conditions for output asymptotic stability of nonlinear nonautonomous time-delay systems described by ordinary differential equations.

Multiomics Profiling During Autoimmune Demyelination Highlights a Complex Regulatory Role for Ataxin‐1 in B Cells

Annals of the New York Academy of Sciences, Volume 1561, Issue 1, July 2026.
Ataxin‐1 has been recently implicated in B cell regulation in the context of multiple sclerosis pathology. In this study, we used a multiomics pipeline to profile the B cell transcriptome, epigenome, and proteome in response to encephalitogenic challenges.

On the Proper Treatment of Dynamics in Cognitive Science

Topics in Cognitive Science, Volume 18, Issue 3, July 2026.
Abstract This essay examines the relevance of dynamical ideas for cognitive science. On its own, the mere mathematical idea of a dynamical system is too weak to serve as a scientific theory of anything, and dynamical approaches within cognitive science are too rich and varied to be subsumed under a single “dynamical hypothesis.” Instead, after first ...

Bioelectrical Interfaces Beyond Excitable Cells: Cancer, Aging, and Gene Expression Modulation

Advanced Materials Interfaces, Volume 13, Issue 10, 19 May 2026.
ABSTRACT The investigation of biological conductivity has evolved from its classical foundation based on ionic fluxes underpinning cardiac and neuronal excitability to a multifaceted regulator of cellular physiology. Traditional approaches for probing electrical events in living matter focused largely on action potentials recording.

RT‐DETR‐DA for Complex Scenes: Distracted Driving Detection With Feature Interaction and Dynamic Perception

Advanced Intelligent Systems, Volume 8, Issue 5, May 2026.
This work proposes RT‐DETR‐DA, an enhanced real‐time detection framework for identifying distracted driving in complex, real‐world environments. The model introduces a dynamic sparse gating multiscale attention module and an attention‐guided dual‐path fusion module to strengthen multiscale perception and cross‐layer feature interaction.

Forecasting the forced van der Pol equation with frequent phase shifts using Reservoir Computing

Machine Learning with Applications
We tested the performance of reservoir computing (RC) in predicting the dynamics of a specific nonautonomous dynamical system. Specifically, we considered a van der Pol oscillator subjected to a periodic external force with frequent phase shifts.

ProCarbon‐Soil: A dynamic model for improved model‐data compatibility in carbon farming

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Carbon farming is a nature‐based solution to capture atmospheric CO2 and store it as soil organic carbon (SOC). Carbon farming trading schemes (CFTS) incentivize farmers to adopt these practices. Integral to CFTS is forecasting SOC changes, typically achieved using traditional multicompartmental soil carbon models (mSCM), and monitoring total ...

‘Escaping Isn't for Everyone’: Kurdish Smugglers’ Navigational Tactics at Checkpoints in Iran

Development and Change, Volume 57, Issue 3, Page 578-598, May 2026.
ABSTRACT This article examines how Kurdish smugglers navigate state and insurgent checkpoints in the borderlands of western Iran. Drawing on ethnographic research, it analyses two key navigational tactics: persin, a form of negotiated passage involving transaction, recognition and the contingent toleration of authority; and jimi, rendered here as ...
