High Resolution Spectroscopy and Spectropolarimetry of some late F-/early G-type sun-like stars as targets for Zeeman Doppler imaging [PDF]
, 2011 High resolution spectroscopy and spectropolarimetry have been undertaken at the Anglo-Australian Telescope in order to identify suitable targets for magnetic studies of young sun-like stars, for the proxy study of early solar evolution. This study involved the investigation of some variable late F-/early G-type sun-like stars originally identified by ...

New approximate solutions of the Ginsparg-Wilson equation - tests in 2-d [PDF]
, 2000 A new method for finding approximate solutions of the Ginsparg-Wilson equation is tested in 2-d. The Dirac operator is first constructed and then used in a dynamical simulation of the 2-flavor Schwinger model. We find a very small mass of the pi-particle

Constructing Improved Overlap Fermions in QCD [PDF]
, 2000 We describe an explicit construction of approximate Ginsparg-Wilson fermions for QCD. We use ingredients of perfect action origin, and further elements. The spectrum of the lattice Dirac operator reveals the quality of the approximation. We focus on beta

Soleus H-reflex Excitability Changes in Response to Sinusoidal Hip Stretches in the Injured Human Spinal Cord [PDF]
, 2007 Imposed static hip stretches substantially modulate the soleus H-reflex in people with an intact or injured spinal cord while stretch of the hip flexors affect the walking pattern in lower vertebrates and humans.

Traversing Racial Distance in Hip-hop Culture: The Ethics and Politics of Listening [PDF]
, 2015 Hip-hop is often studied as a ‘political’ culture. Listeners, however, often contest the attachment of a political nature to hip-hop. After the ‘dilution’ of “real” hip-hop by record labels seeking to package the sound for mainstream consumption, is it ...

Pre- and Post-alpha Motoneuronal Control of the Soleus H-reflex during Sinusoidal Hip Movements in Human Spinal Cord Injury [PDF]
, 2006 The aim of this study was to establish the contribution of hip-mediated sensory feedback to spinal interneuronal circuits during dynamic conditions in people with incomplete spinal cord injury (SCI).

Chiral symmetry in the 2-flavour lattice Schwinger model [PDF]
, 1997 We study the 2-flavour lattice Schwinger model: QED in D=2 with two fermion species of identical mass. In the simulation we are using Wilson fermions where chiral symmetry is explicitly broken.

Wilson, fixed point and Neuberger's lattice Dirac operator for the Schwinger model
, 1998 We perform a comparison between different lattice regularizations of the Dirac operator for massless fermions in the framework of the single and two flavor Schwinger model.

Arthroscopic management of an intraarticular osteochondroma of the hip. [PDF]
, 2009 The role of hip arthroscopy in the management of femoroacetabular impingement (FAI) has been advancing rapidly. In this case report, we describe the use of hip arthroscopy to successfully treat a femoral neck osteochondroma that caused a symptomatic ...

Lightweight and Effective Tensor Sensitivity for Atomistic Neural Networks [PDF]
, 2022 Atomistic machine learning focuses on the creation of models which obey fundamental symmetries of atomistic configurations, such as permutation, translation, and rotation invariances. In many of these schemes, translation and rotation invariance are achieved by building on scalar invariants, e.g., distances between atom pairs. There is growing interest
