Nested sampling for materials: The case of hard spheres [PDF]

open access: yesPhysical Review E, 2014
The recently introduced nested sampling algorithm allows the direct and efficient calculation of the partition function of atomistic systems. We demonstrate its applicability to condensed phase systems with periodic boundary conditions by studying the three-dimensional hard-sphere model. Having obtained the partition function, we show how easy it is to

Origin of life: β‐sheet amyloid conformers as the primordial functional polymers on the early Earth and their role in the emergence of complex dynamic networks

open access: yesFEBS Letters, EarlyView.
The amyloid world hypothesis of the origin‐of‐life posits that the first functional polymers on the early Earth were structurally stable cross‐β‐sheet‐based peptide amyloids capable of Darwinian‐like evolution. Peptide amyloids display self‐replication and information transfer, as well as catalytic, adaptive, and evolutive properties.

Validation of a coupled heat, vapour and liquid moisture transport model for porous materials implemented in CFD [PDF]

open access: yes, 2014
Moisture-related damage is an important issue when looking at the performance of building envelopes. In order to accurately predict the moisture behaviour of building components, building designers can resort to Heat, Air and Moisture (HAM) models.

K-band spectroscopy of pre-cataclysmic variables [PDF]

open access: yes, 2007
Aims. There exists now substantial evidence for abundance anomalies in a number of cataclysmic variables (CVs), indicating that the photosphere of the secondary star incorporates thermonuclear processed material. However, the spectral energy distribution
