A pictorial visualization of normal mode vibrations of the fullerene C_60 molecule in terms of vibrations of a hollow sphere (2010)
Journal Article

Understanding the normal mode vibrations of a molecule is important in the analysis of vibrational spectra. However, the complicated 3D motion of large molecules can be difficult to interpret. We show how images of normal modes of the fullerene molec...

Algebraic approach to quantum field theory on a class of noncommutative curved spacetimes (2010)
Journal Article

In this article we study the quantization of a free real scalar field on a class of noncommutative manifolds, obtained via formal deformation quantization using triangular Drinfel'd twists. We construct deformed quadratic action functionals and compu... Read More about Algebraic approach to quantum field theory on a class of noncommutative curved spacetimes.

Instabilities in the spin-up of a rotating, stratified fluid (2010)
Journal Article

Theoretical analyses and laboratory experiments have been performed on the stability of a flow generated by the differential cyclonic corotation of a flat, rigid disk in a uniformly rotating, linearly stratified fluid contained within a cylindrical t...

Direct visualization of the small hydrophobic protein of human respiratory syncytial virus reveals the structural basis for membrane permeability (2010)
Journal Article

Human respiratory syncytial virus (HRSV) is the leading cause of lower respiratory tract disease in infants. The HRSV small hydrophobic (SH) protein plays an important role in HRSV pathogenesis, although its mode of action is unclear. Analysis of the...

Computer-based learning objects in healthcare: the student experience (2010)
Journal Article

Web-based computer learning objects, such as Reusable Learning Objects (RLOs), are becoming more commonplace in nursing and medical education. However, evaluation of RLOs specifically has been limited. The aim of the study was to determine how RLOs i... Read More about Computer-based learning objects in healthcare: the student experience.

Preferred foliation effects in Quantum General Relativity (2010)
Journal Article

We investigate the infrared (IR) effects of Lorentz violating terms in the gravitational sector using functional renormalization group methods similar to Reuter and collaborators. The model we consider consists of pure quantum gravity coupled to a pr... Read More about Preferred foliation effects in Quantum General Relativity.

Design and assessment spectra for retrofitting of RC buildings (2010)
Journal Article

This article presents a novel approach for deriving Retrofit Design Spectra (RDS) that are intended for use in preliminary development and assessment of seismic upgrading scenarios of existing structures. The new spectral representation relates the c... Read More about Design and assessment spectra for retrofitting of RC buildings.

Adaptivity and a posteriori error control for bifurcation problems I: the Bratu problem (2010)
Journal Article

This article is concerned with the numerical detection of bifurcation points of nonlinear partial differential equations as some parameter of interest is varied. In particular, we study in detail the numerical approximation of the Bratu problem, base... Read More about Adaptivity and a posteriori error control for bifurcation problems I: the Bratu problem.

The change in cerebrovascular reactivity between 3T and 7T measured using graded hypercapnia (2010)
Journal Article

Mapping cerebrovascular reactivity (CVR) to hypercapnia is important both clinically and for improved understanding of the haemodynamic properties of the BOLD effect. In this work BOLD/R2* CVR was investigated by using a device which provided small,... Read More about The change in cerebrovascular reactivity between 3T and 7T measured using graded hypercapnia.

Galaxy Zoo: A correlation between coherence of galaxy spin chirality and star formation efficiency (2010)
Journal Article

We report on the finding of a correlation between galaxies' past star formation activity and the degree to which neighbouring galaxies rotation axes are aligned. This is obtained by cross-correlating star formation histories, derived with MOPED, and...

Effects of photoperiod on daily locomotor activity, energy expenditure, and feeding behavior in a seasonal mammal (2010)
Journal Article

The objective of this study was to determine whether the previously observed effects of photoperiod on body weight in Siberian hamsters were due to changes in the daily patterns of locomotor activity, energy expenditure, and/or feeding behavior. Adul... Read More about Effects of photoperiod on daily locomotor activity, energy expenditure, and feeding behavior in a seasonal mammal.

The influence of bioreactor geometry and the mechanical environment on engineered tissues (2010)
Journal Article

A three phase model for the growth of a tissue construct within a perfusion bioreactor is examined. The cell population (and attendant extracellular matrix), culture medium and porous scaffold are treated as distinct phases. The bioreactor system is...

DnaB proteolysis in vivo regulates oligomerization and its localization at oriC in Bacillus subtilis (2010)
Journal Article

Initiation of bacterial DNA replication at oriC is mediated by primosomal proteins that act cooperatively to melt an AT-rich region where the replicative helicase is loaded prior to the assembly of the replication fork. In Bacillus subtilis, the dnaD... Read More about DnaB proteolysis in vivo regulates oligomerization and its localization at oriC in Bacillus subtilis.

Conditions for linking school mathematics and moral education: a case study (2010)
Journal Article

In recent years the mathematics education research community has undergone a social turn towards a greater interest in the values and broader educational purposes of mathematics education, including issues of social justice and citizenship education....

Expression of AT1R, AT2R and AT4R and their roles in extravillous trophoblast invasion in the human (2010)
Journal Article

The placental renin-angiotensin system (RAS) is active from early pregnancy and may have a role in placentation. Angiotensin II (AngII) acts via binding to receptor types AT1R and AT2R. Recently smaller peptide members of the angiotensin family have... Read More about Expression of AT1R, AT2R and AT4R and their roles in extravillous trophoblast invasion in the human.
