Novel tissue mimicking materials for high frequency breast ultrasound applications
(2011)
The development and acoustical characterisation of a range of novel agar-based tissue
mimicking material (TMMs) for use in clinically relevant, quality assurance (QA) and
anthropomorphic breast phantoms are presented. ...
ALMA Observations of Non-uniform Dust Mass-loss in the Inner Circumstellar Environment of the Red Supergiant VY CMa
(2015)
The processes leading to dust formation and the subsequent role it plays in driving mass loss in cool evolved stars is an area of intense study. Here we present high resolution ALMA Science Verification data of the continuum ...
Star-planet interactions: II. is planet engulfment the origin of fast rotating red giants?
(2016)
Context. Fast rotating red giants in the upper part of the red giant branch have surface velocities that cannot be explained by single star evolution.
Aims. We check whether tides between a star and a planet followed ...
The new physics of non-equilibrium condensates: insights from classical dynamics
(2007)
We discuss the dynamics of classical Dicke-type models, aiming to
clarify the mechanisms by which coherent states could develop in potentially
non-equilibrium systems such as semiconductor microcavities. We present
simulations ...
Exploring the cation dynamics in lead-bromide hybrid perovskites
(2016)
Density functional theory including a many-body treatment of dispersive forces is used to describe the
interplay between structure and electronic properties of two prototypical Br-based hybrid perovskites, namely,
CH
...
Influence of elastic strains on the mask ratio in glassy polymer nanoimprint
(American Institute of Physics, 2005)
During glassy polymer nanoimprint, a supported film is extruded from protruding spunchd to
recessed scavityd regions of a patterned stamp. The completeness of this extrusion determines the
mask ratio for lithographic ...
The kinematics of coronal mass ejections using multiscale methods
(2009)
Aims. The diffuse morphology and transient nature of coronal mass ejections (CMEs) make them difficult to identify and track using traditional image processing techniques. We apply multiscale methods to enhance the visibility ...
EG Andromedae : a symbiotic system as an insight into red giant chromospheres
(Trinity College (Dublin, Ireland). School of Physics, 2012)
Large-scale mechanical peeling of boron nitride nanosheets by low-energy ball milling
(2011)
Mechanical cleavage by Scotch tape was the first method to produce graphene and is still widely used in laboratories. However, a critical problem of this method is the extremely low yield. We have tailored ball milling ...
Quantum transport of Au-S-S-Au nanoscale junctions
(2012)
Transport in S2 molecules sandwiched between Au electrodes is investigated with a combination of density functional theory and the non-equilibrium Green?s function method. We consider four different configurations and find ...
