Degenerate Diffusion Operators Arising in Population Biology
, 2011 We analyze a class of partial differential equations that arise as "backwards Kolmogorov operators" in infinite population limits of the Wright-Fisher models in population genetics and in mathematical finance. These are degenerate elliptic operators defined on manifolds with corners. The classical example is the Kimura diffusion operator, which acts on

Pragmatic turn in biology: From biological molecules to genetic content operators
World Journal of Biological Chemistry, 2014 Erwin Schrödinger's question "What is life?" received the answer for decades of "physics + chemistry". The concepts of Alain Turing and John von Neumann introduced a third term: "information". This led to the understanding of nucleic acid sequences as a natural code. Manfred Eigen adapted the concept of Hammings "sequence space".

Permutation tests for the equality of covariance operators of functional data with applications to evolutionary biology [PDF]
Electronic Journal of Statistics, 2017 In this paper, we generalize the metric-based permutation test for the equality of covariance operators proposed by Pigoli et al. (2014) to the case of multiple samples of functional data. To this end, the non-parametric combination methodology of Pesarin and Salmaso (2010) is used to combine all the pairwise comparisons between samples into a global ...

Is defining life pointless? Operational definitions at the frontiers of biology [PDF]
Synthese, 2017 Despite numerous and increasing attempts to define what life is, there is no consensus on necessary and sufficient conditions for life. Accordingly, some scholars have questioned the value of definitions of life and encouraged scientists and philosophers alike to discard the project.

Enhanced Operational Semantics in Systems Biology [PDF]
, 2003 We are faced with a great challenge: the cross-fertilization between the fields of formal methods for concurrency, in the computer science domain, and systems biology in the biological realm.

Effectiveness of Co-Operative Learning on Achievement in Biology [PDF]
Indian Journal of Applied Research, 2011 The present study investigated the effect of cooperative learning on student's achievement in Biology at Higher Secondary level. The sample of the study was 96 students of XI Std. Experimental group was taught using jigsaw method of cooperative learning and to a control group using traditional method.

A new type of identification problems: optimizing the fractional order in a nonlocal evolution equation [PDF]
, 2016 In this paper, we consider a rather general linear evolution equation of fractional type, namely a diffusion type problem in which the diffusion operator is the $s$th power of a positive definite operator having a discrete spectrum in $\R^+$.
