Testing Methods: The Evaluation of Discovery Operations in Evolutionary Biology [PDF]

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.

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

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.

Pollination biology of Luisia curtisii (Orchidaceae): indications of a deceptive system operated by beetles [PDF]

Plant Systematics and Evolution, 2012
A population of Luisia curtisii (Orchidaceae: Aeridinae) in northern Thailand was studied with regard to pollination biology. Although a high level of self-compatibility was demonstrated experimentally, the very low natural fruit set (1.4–1.9 %) clearly indicated that the species depends on external agents for pollination. Our observations suggest that

Non-Governmental Organizations (NGOs) Operating in the Field of Biology Education in Germany

Journal of Interdisciplinary Education: Theory and Practice, 2023
In the age we live in, humanity is faced with many problems that transcend a nation in a singular sense, but concern all humanity instead. Global climate change, war, terrorism, epidemics such as Covid-19, immigration and injustice in income distribution are some of these problems. However, most of these problems are man-made problems.

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

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 ...

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.
