The prostate cancer detection rate from screening by digital rectal examination and tactilely guided prostate biopsy is approximately 1.7%. Among 1,807 men a detection rate of 14.6% was achieved in a clinical urological practice by physician-conducted prostate ultrasonography, digital rectal examination and determination of serum prostate specific antigen.(More)
We reviewed 225 men who were followed for 2 to 21 years by periodic rectal examination in an effort to detect prostatic cancer without the glands having been sufficiently suspicious for biopsy to have been recommended. These patients underwent further evaluation with transrectal prostatic ultrasonography and serum prostate specific antigen determinations.(More)
This thesis has been read by each member of the following graduate committee and by majority vote has been found to be satisfactory. As chair of the candidate's graduate committee, I have read the thesis of Ryan L. Smith in its final form and have found that (1) its format, citations, and bibliographical style are consistent and acceptable and fulfill(More)
Magnetoresistivity ρ(xx) and Hall resistivity ρ(xy) in ultrahigh magnetic fields up to 88 T are measured down to 0.15 K to clarify the multiband electronic structure in high-quality single crystals of superconducting FeSe. At low temperatures and high fields we observe quantum oscillations in both resistivity and the Hall effect, confirming the multiband(More)
Although air weapons are considerably lower in power than other firearms, there is increasing concern that serious injuries can result from their misuse. The present study was therefore carried out to improve understanding of the terminal ballistic behaviour of air rifle pellets. Pellets were fired into ballistic gel under a variety of conditions. The(More)
A total of 38 patients underwent attempted percutaneous extraction of upper tract calculi with the Wolf nephroscope. A 1-day interval between radiological insertion of the guide wire and extraction of the stone with the patient under general anesthesia was used. Of the stones 87 per cent were removed successfully. Average operating and hospitalization times(More)
We report on the stability of the quantum Hall plateau in wide Hall bars made from a chemically gated graphene film grown on SiC. The ν=2 quantized plateau appears from fields B≃5  T and persists up to B≃80  T. At high current density, in the breakdown regime, the longitudinal resistance oscillates with a 1/B periodicity and an anomalous phase, which we(More)
