Cosmological Constraints from Multiple Probes in the Dark Energy Survey.

The combination of multiple observational probes has long been advocated as a powerful technique to constrain cosmological parameters, in particular dark energy. The Dark Energy Survey has measured 207 spectroscopically confirmed type Ia supernova light curves, the baryon acoustic oscillation feature, weak gravitational lensing, and galaxy clustering. Here we present combined results from these probes, deriving constraints on the equation of state, w, of dark energy and its energy density in the Universe.

Transthoracic needle biopsy of the lung: results of early discharge in 506 outpatients.

Purpose: To determine the safety of early discharge (30 minutes) after transthoracic needle biopsy (TTNB) of the lung.

Materials And Methods: In a prospective study of 506 consecutive outpatients who underwent TTNB of the lung, 440 patients underwent fine-needle aspiration biopsy (FNAB) only, and 66 underwent FNAB and core biopsy. Patients were discharged after 30-minute postbiopsy chest radiography if there was no pneumothorax.

New limit on CPT violation.

A search for antiproton decay has been made at the Fermilab Antiproton Accumulator. Limits are placed on fifteen antiproton decay modes. The results are used to place limits on the characteristic mass scale m(X) that could be associated with CPT violation accompanied by baryon number violation.

Search for a W' boson via the decay mode W'-->munumu in 1.8 TeV pp collisions.

We report the results of a search for a W' boson produced in pp collisions at a center-of-mass energy of 1.8 TeV using a 107 pb-1 data sample recorded by the Collider Detector at Fermilab. We consider the decay channel W'-->&munumu and search for anomalous production of high transverse mass munumu lepton pairs.
