Scaling properties of growing noninfinitesimal perturbations in space-time chaos
, 2004 We study the spatiotemporal dynamics of random spatially distributed noninfinitesimal perturbations in one-dimensional chaotic extended systems. We find that an initial perturbation of finite size $\epsilon_0$ grows in time obeying the tangent space ...

Creating Dynamic Maps of Noise Threat Using PL-Grid Infrastructure
Archives of Acoustics, 2013 Abstract The paper presents functionality and operation results of a system for creating dynamic maps of acoustic noise employing the PL-Grid infrastructure extended with a distributed sensor network. The work presented provides a demonstration of the services being prepared within the PLGrid Plus project for measuring, modeling and rendering data

On dissipation in crackling noise systems
, 2018 We consider the amount of energy dissipated during individual avalanches at the depinning transition of disordered and athermal elastic systems. Analytical progress is possible in the case of the Alessandro-Beatrice-Bertotti-Montorsi (ABBM) model for ...

Semantic SLAM With More Accurate Point Cloud Map in Dynamic Environments
IEEE Access, 2020 Static environment is a prerequisite for most existing vision-based SLAM (simultaneous localization and mapping) systems to work properly, which greatly limits the use of SLAM in real-world environments.

On the Dynamical Behavior of Solitary Waves for Coupled Stochastic Korteweg–De Vries Equations
Mathematics, 2023 In this paper, we take into account the coupled stochastic Korteweg–De Vries (CSKdV) equations in the Itô sense. Using the mapping method, new trigonometric, rational, hyperbolic, and elliptic stochastic solutions are obtained.

Past, Present, and Future of Simultaneous Localization And Mapping: Towards the Robust-Perception Age [PDF]
, 2016 Simultaneous Localization and Mapping (SLAM)consists in the concurrent construction of a model of the environment (the map), and the estimation of the state of the robot moving within it.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Spatio-Temporal Detection and Filtering of Dynamic Objects in Mobile LiDAR Point Clouds [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesMobile LiDAR systems are increasingly utilized for high-precision mapping in dynamic environments, yet the presence of moving objects introduces significant noise and distortions in the resulting point clouds.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
