Analysis of Degenerate Diffusion Operators Arising in Population Biology

2012
In this chapter, we describe our recent work on the analytic foundations for the study of degenerate diffusion equations which arise as the infinite population limits of standard models in population genetics. Our principal results concern existence, uniqueness, and regularity of solutions when the data belong to anisotropic Holder spaces, adapted to ...

Stochastic Operators and Semigroups and Their Applications in Physics and Biology

2014
Stochastic operators are positive linear operators defined on the space of integrable functions preserving the set of densities. They appear in many fields of mathematics and applications and they are use to study ergodic properties of dynamical systems and describe the evolution of Markov chains.

Co-operation of Biology Related Algorithms for Multi-objective Binary Optimization

2015 IIAI 4th International Congress on Advanced Applied Informatics, 2015
A modification of the self-tuning meta-heuristic, called Co-Operation of Biology Related Algorithms, for multiobjective optimization problems with binary variables (COBRA-bm) is introduced. Its basic idea consists of a cooperative work of five well-known bionic algorithms such as the Particle Swarm Optimization, the Wolf Pack Search, the Firefly ...

Complex control of a human scale tele-operating system for cell biology

Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527), 2003
In the medical field and in biotechnology application, a new type of human scale teleoperating system that can carry out three-dimensional high-speed micromanipulation has urgently been demanded. It is our purpose to develop a new type of human scale operating system for microoperation that can manipulate a microobject.

Co-Operation of Biology-Related Algorithms for Constrained Multiobjective Optimization

2015
A modification of the self-tuning meta-heuristic, called Co-Operation of Biology Related Algorithms for multiobjective optimization problems COBRA-m is introduced. Its basic idea consists of a cooperative work of five well-known bionic algorithms such as Particle Swarm Optimization, Wolf Pack Search, the Firefly Algorithm, the Cuckoo Search Algorithm ...

Rho GTPases operating at the Golgi complex: Implications for membrane traffic and cancer biology

Tissue and Cell, 2017
The Golgi complex is the central unit of the secretory pathway, modifying, processing and sorting proteins and lipids to their correct cellular localisation. Changes to proteins at the Golgi complex can have deleterious effects on the function of this organelle, impeding trafficking routes through it, potentially resulting in disease.

Does terminology from biology work in the realm of operant behaviour?

Behavioral and Brain Sciences, 2001
The authors note that theoretical revision is likely to be required to refine and clarify a general theory of selection so that it is capable of accounting for selection processes across different subject matters. Some aspects of conceptual language from the biological realm work across all three domains.

Biologie des Prostatacarcinoms und seine operative Behandlung

1973
Nach dem Lungenkrebs steht das Prostatacarcinom an zweiter Stelle als Todesursache an Krebs in der mannlichen Bevolkerung der USA (etwa 17600 Todesfalle im Jahre 1972)1. Die heutige Behandlung des Prostatacareinoms kann von zwei wesentlichen Gesichtspunkten aus betrachtet werden: 1.
