We report the detection of 15 GHz radio continuum emission associated with the classical Cepheid variable star δ Cephei ( δ Cep) based on observations with the Karl G. Jansky Very Large Array. Our results constitute the first probable detection of

Nietzsche and Classical Greek Philosophy: Beautiful and Diseased explains Friedrich Nietzsche's ambivalence toward Socrates, Plato, and Aristotle. Daw-Nay N. R. Evans Jr. argues that Nietzsche's relationship to his classical Greek predecessors is mor

This study evaluated the impact of the Salisbury Protocol for Assessment of Cauda Equina Syndrome (SPACES) on the waiting time for MRI in patients presenting with suspected Cauda Equina Syndrome (sCES) within a UK district general hospital.All consec
Classical Cepheids are essential objects in the study of stellar evolution and cosmology; however, we know little about their magnetic properties. We report the detection of Stokes $V$ features interpreted as Zeeman signatures in four classical Cephe

gamma Cas has long been famous for its unique hard X-ray characteristics. We report herein on a 53 ks Chandra HETGS observation of this target. An inspection of our spectrum shows that it is quite atypical for a massive star, with abnormally weak Fe

For about 100 years the amplitude of the 4-day pulsation in Polaris has decreased. We present new results showing a significant increase in the amplitude based on 4.5 years of continuous monitoring from the ground and with two satellite missions.

The 6.4 day classical Cepheid AW Per is a spectroscopic binary with a period of 40 years. Analyzing the centroids of HST/STIS spectra obtained in November 2001, we have determined the angular separation of the binary system. Although we currently hav

We present followup optical g', r', and i', imaging and spectroscopy of serendipitous X-ray sources detected in 6 archival Chandra, images included in the Chandra, Multiwavelength Project (ChaMP). Of the 486 X-ray sources detected between 3e-16 and 2
