The first cosmological results from the ESSENCE supernova survey (Wood-Vasey et al. 2007) are extended to a wider range of cosmological models including dynamical dark energy and non-standard cosmological models. We fold in a greater number of external data sets such as the recent Higher-z release of high-redshift supernovae (Riess et al. 2007) as well as(More)
We present constraints on the dark energy equation-of-state parameter, w = P/(ρc 2), using 60 Type Ia supernovae (SNe Ia) from the ESSENCE su-pernova survey. We derive a set of constraints on the nature of the dark energy assuming a flat Universe. By including constraints on (Ω M , w) from baryon acoustic oscillations, we obtain a value for a static(More)
Type Ia Supernovae hold great promise to measure the cosmic deceleration. The diversity observed among these explosions, however , complicates their ability to measure cosmological parameters considerably. The comparison of near and distant objects depends critically on the global properties of the samples. Systematic errors are introduced in cases where(More)
Immunological deposits in the testis and circulating antibodies to spermatozoa are presented as a possible explanation for infertility in man. Testicular biopsy specimens from infertile patients (N = 52) as well as from fertile controls (N = 6) were analyzed immunohistochemically by using semithin sections. Immunoglobulin deposits were found in the testes(More)
Between 1983 and 1985, 257 infertile men were examined for any present varicocele by means of the Doppler sonography, telethermography and palpation. Based on these findings, the spermiogram and the infertility history, high ligation of the spermatic vein was indicated in 89 patients with varicocele and a median duration of infertility of 36 months (6-88(More)
The High-z Supernova Search Team has discovered and observed 8 new supernovae in the redshift interval z = 0.3–1.2. These independent observations, analyzed by similar but distinct methods, confirm the result of Riess et al. (1998a) and Perlmutter et al. (1999) that supernova luminosity distances imply an accelerating universe. More importantly, they extend(More)
PURPOSE The incidence of mumps orchitis has declined dramatically since the introduction of vaccination. While in the past cases of mumps have only been seen occasionally at our institution, recently there has been a sharp increase in the number of confirmed cases. MATERIALS AND METHODS Between June 1995 and April 1996, 11 patients with severe mumps(More)
Because of the increasing number of divorces surgical refertilisation by vasovasostomy has become increasingly important. Of 33 patients operated in the last decade, 32 could be reached for follow-up. The patency-rate was 86% and the pregnancy-rate 28%. Possible explanations for this discrepancy are discussed. The time lag between vasectomy and(More)
We present early time high-resolution (VLT/UVES) and late time low-resolution (VLT/FORS) optical spectra of the normal type Ia supernova, SN 2001el. The high-resolution spectra were obtained 9 and 2 days before (B-band) maximum light. This was in order to allow the detection of narrow hydrogen and/or helium emission lines from the circumstellar medium of(More)
We present photometric and spectroscopic observations of 23 high redshift supernovae spanning a range of z = 0.34 − 1.03, 9 of which are unambiguously classified as Type Ia. These supernovae were discovered during the IfA Deep Survey, which began in September 2001 and observed a total of 2.5 square degrees to a depth of approximately m ≈ 25 − 26 in RIZ over(More)
