Tailoring spatiotemporal dynamics of plasmonic vortices

Opto-Electronic Advances, 2023
Plasmonic vortices confining orbital angular momentums to surface have aroused wide research interest in the last decade. Recent advances of near-field microscopes have enabled the study on the spatiotemporal dynamics of plasmonic vortices, providing a ...

Towards a verifiable, uncertainty-controlled assessment of the spatiotemporal dynamics of social vulnerability to flash floods

Ecological Indicators
While research on quantitative measures of vulnerability is increasing, current studies may be criticized for failing to consider the spatiotemporal dynamics of vulnerability, ignoring uncertainty in the assessment process, and lacking validation.

Spatiotemporal dynamics of mammalian wound healing. [PDF]

Cell Discov
Abstract Mammalian wound healing is orchestrated by tightly regulated cellular and molecular programs across the hemostasis, inflammation, proliferation, and remodeling phases. Here, we propose the concept of spatiotemporal clocks as a unifying framework for understanding how transitions between phases are coordinated.

Metasurface spatiotemporal dynamics and asymmetric photonic spin-orbit interactions mediated vector-polarization optical chaos

Physical Review Research, 2021
We theoretically investigate metasurface spatiotemporal dynamics by introducing laser chaotic dynamics into metasurface domain. The spatiotemporal dynamics takes advantage of both the time-dependent dynamics of optical chaos and the local spatial ...

Spatiotemporal Dynamics of Actomyosin Networks [PDF]

Biophysical Journal, 2013
Rhodamine-phalloidin-labeled actin filaments were visualized gliding over a skeletal heavy meromyosin (HMM)-coated surface. Experiments at low filament densities showed that when two filaments collided, their paths were affected in a manner that depended on collision angle. Some collisions resulted in complete alignment of the filament paths; in others,

Dynamic spatiotemporal ARCH models

Spatial Economic Analysis, 2023
Geo-referenced data are characterised by an inherent spatial dependence due to geographical proximity. In this paper, we introduce a dynamic spatiotemporal autoregressive conditional heteroscedasticity (ARCH) process to describe the effects of (i) the log-squared time-lagged outcome variable, the temporal effect, (ii) the spatial lag of the log-squared

Unveiling the complexity of spatiotemporal soliton molecules in real time

Nature Communications, 2023
Observing the dynamics of 3D soliton molecules can hold great opportunities for unveiling the mechanism of molecular complexity and other nonlinear problems.

Securin Regulates the Spatiotemporal Dynamics of Separase

Journal of Cell Biology, 2023
Abstract Separase is a key regulator of the metaphase to anaphase transition with multiple functions. Separase cleaves cohesin to allow chromosome segregation and localizes to vesicles to promote exocytosis in mid-anaphase. The anaphase promoting complex/cyclosome (APC/C) activates separase by ubiquitinating its inhibitory chaperone ...

Intra-annual land cover mapping and dynamics analysis with dense satellite image time series: a spatiotemporal cube based spatiotemporal contextual method

GIScience & Remote Sensing, 2021
Land covers provide essential information for understanding and detecting ecosystem, resources, and environmental dynamics. However, they are generally mapped at coarser temporal scales to study the inter-annual changes, while scant attention has been ...
