Morphodynamics of phyllotaxis

open access: yesThe International Journal of Developmental Biology, 2006
A morphodynamic model for phyllotaxis based upon an axiomatic approach is presented. We show that the helical forms of alternate phyllotaxis can be derived from the assumption of the rudiment's growth and movement on the cylindrical embryo surface in the absence of a longitudinal displacement.

Observation of Rapid Seabed Erosion Near Closure Depth During a Storm Period at Hujeong Beach, South Korea

open access: yesGeophysical Research Letters, 2019
We report extraordinary seabed erosion that occurred at a depth of ~8.3 m at Hujeong Beach, South Korea. The seabed was eroded for 0.7 m during a ~2.3‐day period under storm conditions. The maximum significant wave height was ~3.8 m, which was unexpected

Profiling cellular morphodynamics by spatiotemporal spectrum decomposition. [PDF]

open access: yesPLoS Computational Biology, 2018
Cellular morphology and associated morphodynamics are widely used for qualitative and quantitative assessments of cell state. Here we implement a framework to profile cellular morphodynamics based on an adaptive decomposition of local cell boundary ...

The Teleodynamics of Language, Culture, Technology and Science (LCT&S)

open access: yesInformation, 2013
Logan [1] in his book The Extended Mind developed the hypothesis that language, culture, technology and science can be treated as organisms that evolve and reproduce themselves.

Mitochondrial morphodynamics alteration induced by influenza virus infection as a new antiviral strategy.

open access: yesPLoS Pathogens, 2021
Influenza virus infections are major public health threats due to their high rates of morbidity and mortality. Upon influenza virus entry, host cells experience modifications of endomembranes, including those used for virus trafficking and replication ...

Observing and Predicting Coastal Erosion at the Langue de Barbarie Sand Spit around Saint Louis (Senegal, West Africa) through Satellite-Derived Digital Elevation Model and Shoreline

open access: yesRemote Sensing, 2021
Coastal erosion at Saint Louis in Senegal is affecting the local population that consists of primarily fishermen communities in their housing and their access to the sea.

Lagoon water-level oscillations driven by rainfall and wave climate [PDF]

open access: yes, 2017
Barrier breaching and subsequent inlet formation represent critical processes that ensure the temporary or permanent connection and transference of water, nutrients, or living organisms between a lagoon and the open sea.

Performance Evaluation of Wave Input Reduction Techniques for Modeling Inter-Annual Sandbar Dynamics

open access: yesJournal of Marine Science and Engineering, 2019
In process-based numerical models, reducing the amount of input parameters, known as input reduction (IR), is often required to reduce the computational effort of these models and to enable long-term, ensemble predictions.

Extraction of tidal channel networks from airborne scanning laser altimetry and aerial photography [PDF]

open access: yes, 2003
The study of the morphodynamics of tidal channel networks is important because of their role in tidal propagation and the evolution of salt-marshes and tidal flats. Channel dimensions range from tens of metres wide and metres deep near the low water mark

T‐Cell Exhaustion in the Tumor Microenvironment: Subcellular Dysfunction, Pan‐Cancer Characteristics, and Therapeutic Interventions

open access: yesAdvanced Science, EarlyView.
This study elucidates the mechanisms of subcellular multidimensional collapse in exhausted T cells. By specifically targeting the nucleus, mitochondria, and endoplasmic reticulum, strategic interventions can effectively remodel the compromised organelle network. This integrated approach drives comprehensive T cell resuscitation, ultimately establishing
