The parameterisation of rotations in three dimensional Euclidean space is an area of applied mathematics that has long been studied, dating back to the original works of Leonhard Euler in the 18th century. As such, many ways of parameterising a rotation have been developed over the years. Motivated by the task of representing the orientation of a balancing body, the fused angles parameterisatio...

Phenotypic studies continue to contribute to an understanding of the functions of cytoskeletal proteins. Many of these studies indicate some degree of functional redundancy within a family of cytoskeletal proteins. Some surprises have emerged, such as suggestions of unexpected relationships between the actin and microtubule cytoskeletons. Finally, phenotypic studies have provided evidence for a...

A particular kind of quintessence is considered, with equation of motion pQ/ρQ = −1, corresponding to a cosmological term with time-dependence Λ(t) = Λ(t0)(R(t0)/R(t)) P which we examine initially for 0 ≤ P < 3. Energy conservation is imposed, as is consistency with big-bang nucleosynthesis, and the range of allowed P is thereby much restricted to 0 ≤ P < 0.2. The position of the first Doppler ...

There are many software languages which are not exposed protocols, exchange formats, interfaces and storage formats, and are only used for intermediate representation, runtime data manipulation and tool-specific serialisation. Yet, they can be important for technology comprehension, since such internal implementation details may have indirect impact on some aspects of the externally observed be...

In this work we present a biologically inspired algorithm for learning object categories that uses Bayesian inference to integrate information within and across fixations. In our model, an object is represented as a collection of features of specific classes arranged at specific locations with respect to the location of the fixation point. Even though the number of feature detectors that we use...
