Spatial distribution of phytochromes

Journal of Plant Research, 1997
Phytochromes are chromoproteins which mediate several light responses in plants. Phytochrome proteins are encoded by a gene family which is currently being characterized in several plant species. Analysis of type-specific mutants of two well-characterized members of the family, PhyA and PhyB, indicates that these proteins have distinct functions.

Spatial Modelling of Seablite Distribution

2021
Foods demands are increasing today opposed to the change in environmental degradation. In this work, we studied new seablite distribution modelling. We aimed to identify substantial basic factors related to spatial distribution of seablites to make a meaningful explanation or accurate prediction in a coastal region of Samut Sakhon, Thailand.

Spatial movement with distributed memory

Journal of Mathematical Biology, 2021
Diffusion has been widely applied to model animal movement that follows Brownian motion. However, animals typically move in non-Brownian ways due to their perceptual judgment. Spatial memory and cognition recently have received much attention in characterizing complicated animal movement behaviours.

SPATIAL OLIGOPOLIES WITH COOPERATIVE DISTRIBUTION

International Game Theory Review, 2009
The main objects here are Nash equilibria in spatial Cournot oligopolies when profits depend on coordinated distribution. Production is non-cooperative, but the subsequent transportation must be performed jointly to minimize costs. Cournot-Nash equilibria for this two-stage game with partial coalitional strategies are determined by means of a ...

Spatial Distribution

2008
Living organisms are distributed over the entire surface of the planet. The distribution of the individuals of each species is not random; on the contrary, they are strongly dependent on the biology and ecology of the species, and vary over different spatial scale.

Spatial join strategies in distributed spatial DBMS

1995
In a distributed spatial database system, a user may issue a query that relates two spatial relations that are stored at different sites. Because of the sheer volume and complexity of spatial data, spatial joins between two spatial relations at different sites are expensive in terms of computation and transmission cost.

Distributed Spatial Data Warehouse

2004
Data warehouses are used to store large amounts of data. A data model makes possible separating data categories and establishing relations between them. In this paper we introduce for the first time the new concept of distributed spatial data warehouse based on the multidimensional data model called cascaded star schema [1].

The Spatial Distribution of Inhibition of Return

Psychological Science, 2001
Inhibition of return (IOR) refers to the finding that response times (RTs) are typically slower for targets at previously attended (cued) locations than for targets at novel (uncued) locations. Although previous research has indicated that IOR may spread beyond a cued location, the present study is the first to examine the spatial distribution of IOR ...

Spatial distribution of dispersing animals

Journal of Mathematical Biology, 1980
A mathematical model for the dispersal of an animal population is presented for a system in which animals are initially released in the central region of a uniform field and migrate randomly, exerting mutually repulsive influences (population pressure) until they eventually become sedentary.

Spatial distribution of cloud cover

International Journal of Satellite Communications and Networking, 2008
AbstractSatellite systems and high‐altitude platform systems working in Ka and V bands require the application of adaptive techniques in order to mitigate link degradations caused by atmospheric impairments such as those due to cloud cover. Among these techniques, resource sharing system techniques and site diversity need information on the spatial ...
