Dynamic river networks drive landscape change and biological evolution
… ways in which these processes may influence the evolution of aquatic life. In Chapters 1-3 of my thesis I investigate river network reorganization, a phenomenon that occurs when some river basins erode faster than their neighbors, growing at their expense. The exchange of drainage area across …

Biological evolution and population change in the European Upper Palaeolithic
… skeletal material, studies of late Pleistocene evolutionary change remain inconclusive. The work which has been conducted on Upper Palaeolithic cranial change has proposed that there are regional patterns and differences in cranial robusticity which has been interpreted as genetic admixture …

Postsecondary Students’ Perceptions Toward Accepting and Understanding Biological Evolution: A Qualitative Metasynthesis
… perceptions towards accepting and understanding evolution. Evolution as a process and theory is a foundation for understanding the biological sciences. Within the scientific and educational communities, evolution is a central theme tying the fabric of the biological sciences together. A …

"Evo in the News": A Pedagogical Tool to Enhance Students' Perceptions of the Relevance of Evolutionary Biology
… News" on the attitudes toward and knowledge of biological evolution in a sample of undergraduate non-major biology students at a large, private research university. In addition, this study looked at the initial attitudes of the students and their knowledge of evolution before beginning a second …

In Silico Evolution of Oscillating Mass-Action Chemical Reaction Networks
Evolutionary algorithms, a class of optimization techniques inspired by biological evolution,have emerged as powerful tools for the optimization of complex systems, including the evolution of mass-action chemical reaction networks. This dissertation explores the application of evolutionary …

Evolving Minds: Helping Students with Cognitive Dissonance
… with student resistance to learning about biological evolution. Some teachers deal with this pressure by undermining, deemphasizing, or even omitting the topic in their science curriculum. Others face the challenge and deliver solid scientific instruction of evolutionary theory despite the …

Carbon and sulfur isotopic constraints on Ediacaran biogeochemical processes, Huqf supergroups, Sultanate of Oman
The link between environmental and evolutionary change is investigated in the Ediacaran Period (- 635 - 541 million years ago (Ma), an interval where we see the emergence of macroscopic animals along with large perturbations to the carbon and sulfur cycles. Paleoenvironmental reconstruction used …

The synthesis of artificial neural networks using single string evolutionary techniques.
… techniques are based on computer modelling of biological evolution or foetal development. They are known as Evolutionary, Genetic or Embryological methods. Specifically, Embryological techniques are used to grow Artificial Neural Network topologies. The Embryological Algorithm is an alternative …

The tropical cyclone-induced flux of carbon between the ocean and the atmosphere
… inputs, which tracks the physical, chemical, and biological evolution of the ocean's mixed layer in response to atmospheric forcing. Its ability to recreate the observed ocean state is tested. This model is used to simulate a real region of ocean, both with and without the mixing induced by a …

Designing Visual Intelligence from Photons to Action
… and safe actions; a process fundamental to both biological and human-engineered systems. Nature has evolved highly attuned visual systems, resulting in diverse and efficient eyes capable of facilitating complex behaviors. Conversely, roboticists have engineered sophisticated cameras and sensors, …

Natural Selection and Natural Processes: a philosophical examination of the processes of evolution
This thesis concerns evolution and how it is explained. The ambition here is to identify clearly the many aspects of evolution, and to evaluate past and present explanations of evolution for their coherence and validity. Historically natural selection has been taken to be the central and main …

Atom-by-atom designs of metal oxide catalysts for the oxygen evolution reaction
… energy technologies is essential. The oxygen evolution reaction (OER) holds great promise, as it enables the production of green chemicals, hydrogen gas, and pure metals electrolytically from their oxides, with oxygen as the sole byproduct. However, OER suffers from slow reaction kinetics and …

The Anxiety Of Evolution: Biological And Cultural Adaptation From Marcel Proust To Peter Greenaway
… metaphors, images, and narrative structures of biological evolution and (post-)Darwinian theory. It argues that, in so doing, they have often tended to reveal their own anxieties concerning the status of art and human beings (typically men), rather than provide a so-called objective model for …

A dynamical model of the distributed interaction of intracellular signals
… which is designed to mimic features of real biological evolution. An analogue of protein domain shuffling is used as the crossover operator and cells are reproduced asexually. The effects of changing the parameters of the GA are explored. A clustering algorithm is developed to test the …

Tempo geológico e o ensino de Biologia: investigando uma proposta de Sequência Didática baseada em Design Research.
Basic concept in Geoscience, decisive for the evolution of scientific thinking and paradigm shift that culminated in the acceptance that the history of humanity is much more recent than the history of the planet, Geological Time is fundamental for teaching Evolution and for perception of emerging …

Biophysical and structural characterization of components from the nuclear pore complex and the ubiquitin pathway
… system in the eukaryotic cell is a hallmark of biological evolution. One such system is the nuclear envelope (NE), composed of an inner and outer membrane, used to form a nucleus and enclose the cell's genome. Access to the nucleus from the cytoplasm is mediated by a massive macromolecular …
