Towards a theory of meaning in biology: a proposal for an operative definition.

Rivista di biologia, 2003
Information is a concept developed inside the context of computational and computer sciences. Entropy is a concept developed inside physics context. The best concept in biology is that of "meaning" which is quite impossible to be measured as stated by some examples which are reported.

Robotnov function based operator for biological population model of biology

International Journal of Numerical Methods for Heat & Fluid Flow, 2021
Purpose The population model has an important role in biology to interpret the spreading rate of viruses and parasites. This biological model is also used to identify fragile species. This paper aims to propose a new Yang-Abdel-Aty-Cattani (YAC) fractional operator with a non-singular kernel to solve nonlinear partial differential equation, which is ...

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

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.

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 ...
