Approximate Bayesian Computation Scheme For Parameter Inference And Model Selection In Dynamical Systems

For the vast majority of biological systems we have no idea as to which mathematical description is best and this ignorance seriously hinders progress in many areas of the biomedical sciences. Unfortunately, parameters often cannot be measured experimentally. We developed a new statistical technique applicable to models that can be easily simulated, and for which a time series data is available.

Hysteresis Of Soft Joints Embedded With Fluid-Filled Micro-Channels

Arthropods like cockroaches, locusts, grasshoppers and many others do not have an elaborate nervous system e.g. the reflex action, unlike us, the mammalians; yet, they achieve significant dynamic stability during rapid locomotion on rough terrains. Similarly, many flying insects too stabilize their flight against turbulent wind and fluctuations during flight transition from hovering to flapping modes.

Biomolecular Simulation And Modelling: Status, Progress And Prospects
10.07.2008 07:16
medicalnewstoday.com
Molecular simulation is increasingly demonstrating its practical value in the investigation of biological systems. Computational modelling of biomolecular systems is an exciting and rapidly developing area, which is expanding significantly in scope. A range of simulation methods have been developed that can be applied to study a wide variety of problems in structural biology, and at the interfaces between physics, chemistry and biology.

A Keystone Effect For Parasites In Intraguild Predation?
10.07.2008 07:16
medicalnewstoday.com
A major challenge for ecologists is to understand how different species coexist and the factors that promote their persistence or contribute to their decline. Recently ecologists have become interested in the role of parasites in these processes. Parasites are important components of ecological communities and can potentially have "keystone effects", altering the outcomes of interactions between other species.

Candidate Neural Locus For Sex Differences In Reproductive Decisions
10.07.2008 06:16
medicalnewstoday.com
Frogs have sex differences in behavior, with male frogs typically being less selective than females in behavioral responses. We examined the brains of frogs to determine whether the sexes hear differently, perceive the calls differently by differential auditory processing, or act differently based on similar auditory system information. We argue that the sexes are similar in their specificity at early stages of the auditory system.

An Ancient Tripartite Symbiosis Of Plants, Ants And Scale Insects
10.07.2008 06:16
medicalnewstoday.com
In this paper we infer the antiquity of an obligate tripartite association involving symbiotic ants, plants and scale insects in the tropical rain forests of Southeast Asia. The prevalence of scale insect associates in ant-plant mutualisms at large suggests they play an important role in the evolutionary origins of these mutualisms. Previous studies estimate the association between the ants and plants to be 16-20 million years old.

Adaptive Numerical Competency In A Food-Hoarding Songbird
10.07.2008 05:12
medicalnewstoday.com
Knowledge of mathematics is thought to distinguish humans from other animals. However, the potential for wild animals to use number discriminations to solve ecological problems is poorly resolved. We conducted a series of experiments to test whether a food-hoarding songbird, the New Zealand robin Petrocia australis, could discriminate between cache sites containing different numbers of prey.

Life History Constrains Biochemical Development In The Highly Specialized Odontocete Echolocation System
10.07.2008 05:12
medicalnewstoday.com
We describe a new link between physiological development of a highly derived mammalian tissue, and life history constraints. The heads of vertebrates are recognized as potentially being the body part that shows the most diversity. Toothed whales have evolved very complex and unique cranial adipose tissues for acoustic transmission and reception (echolocation).
