Observations of DNA transfer within an operational Forensic Biology Laboratory

Forensic Science International: Genetics, 2016
Advances in technology to both generate and interpret DNA profiles has seen the expansion of the ability to provide opinions about results obtained from very low levels of starting biological material. The response in court has been to question the mode by which the DNA came to be on an item, rather than questioning its presence.

Integr8: Enhanced Inter-Operability of European Molecular Biology Databases

Methods of Information in Medicine, 2003
Summary Objectives: The increasing production of molecular biology data in the post-genomic era, and the proliferation of databases that store it, require the development of an integrative layer in database services to facilitate the synthesis of related information.

Use of operative temperature and standard operative temperature models in thermal biology

Journal of Thermal Biology, 2005
Abstract Operative temperature ( T e ) and standard operative temperature ( T es ) models have been used to address ecological questions about the thermal biology of ectotherms and endotherms for over 25 years. This review focuses on the accuracy and use of T e and T es models in ecological and physiological studies. The utility of T e and

Biology and prognosis by age of primary operable breast cancer.

Cancer Research, 2009
Abstract Abstract #2082 Introduction Breast cancer (BC) biology and prognosis are age dependent. We studied the effect of age on BC biology, treatment and prognosis.
 Methods Data from 2059 consecutive patients, primary operated for invasive BC in UZ Leuven (01/01/00–01/06/05), were used. Patients with ≥ 3.5 yrs

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 ...

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 ...

Peri-operative biology in primary breast cancer: a credible therapeutic target

Breast Cancer Research and Treatment, 2016
Over the last 25 years, there has been a growing body of basic science, modeling, and clinical data suggesting that the peri-operative period in the treatment of primary breast cancer is dynamic and can be manipulated to improve long-term outcomes. Clinical data have demonstrated early peaks of hazards for recurrence and emphasized the relationship of ...

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.

Testing Methods: The Evaluation of Discovery Operations in Evolutionary Biology

Cladistics, 2002
Scientific discovery requires both abstract, theoretically defined concepts and discovery operations formed by sets of rules that permit the empirical detection of instances of those concepts. In this paper, I examine the ontological status of discovery operations and the tests employed to evaluate them in evolutionary biology.

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 ...
