Electronic distribution coding in cellular differentiation

Journal of Theoretical Biology, 1973
Abstract The present theories of cell differentiation explain how different types of cells can be obtained, starting from a single cell or cell type, through the action of gene repressors. They do not, however, provide a model for the primary step, i.e.

The Differential Distribution of Community Knowledge

Social Forces, 1951
from a weighing of divergent evidence and a resulting choice. Rural dwellers, denied such choice, must perforce make decisions in terms of their traditional values-which may or may not be adequate to meet the present situation. The South is characterized by a high percentage of its people living under rural conditions.

Singular differential operators and distributions

Israel Journal of Mathematics, 1981
Differential operatorsp(t, ∂)=am (t)∂m +···+a0(t), wheream has a zero of finite order att=0, are studied as operators on the distribution spacesD'(R) andE'(R). In particular the kernel ofp, operating onD'(R), is studied in detail by use of asymptotic analysis and a simple formula for its dimension is given.

Estimation Distribution Differential Evolution

2010
This paper proposes a novel adaptation scheme for Differential Evolution (DE) frameworks. The proposed algorithm, namely Estimation Distribution Differential Evolution (EDDE), is based on a DE structure and employs randomized scale factor ad crossover rate values.

DIFFERENTIAL OPERATORS ON SCHWARTZ DISTRIBUTIONS

International Journal of Geometric Methods in Modern Physics, 2012
Differential operators on Schwartz distributions usually are defined as the transpose of differential operators on test functions. However, they do not exhaust all differential operators. In a general setting, Schwartz distributions on sections of compact support of a vector bundle Y over a smooth manifold X are considered.

Differentiated Capital and the Distribution of Wealth

2005
We present a one-sector growth model with finitely many households who differ from each other with respect to their endowments, their preferences, and the type of capital supplied to firms. There is monopolistic competition on the capital market and perfect competition on all other markets.

Autonomy and Differentiation in Distributed Systems

2013
A bio-inspired approach for self-adaptive software agents on distributed systems is presented. It introduces the notion of (de)differentiation in cellular slime molds, e.g., dictyostelium discoideum, into real distributed systems. When an agent delegates a function to another agent coordinating with it, if the former has the function, this function ...
