Pushing the precision limit of ground-based eclipse photometry
Until recently, it was considered by many that ground-based photometry could not reach the high cadence sub-mmag regime because of the presence of the atmosphere. Indeed, high frequency atmospheric noises (mainly scintillation) limit the precision that high SNR photometry can reach within small time bins. If one is ready to damage the sampling of his photometric time-series, binning the data (o...
متن کاملCorrelating the Ancient Maya and Modern European Calendars with High-Precision AMS 14C Dating
The reasons for the development and collapse of Maya civilization remain controversial and historical events carved on stone monuments throughout this region provide a remarkable source of data about the rise and fall of these complex polities. Use of these records depends on correlating the Maya and European calendars so that they can be compared with climate and environmental datasets. Correl...
متن کاملPushing NRQCD to the limit
Lattice NRQCD has proven successful in describing the physics of the upsilon system and B mesons, though some concerns arise when it is used in simulations of charm quarks. It is certainly possible that the NRQCD expansion is not converging fast enough at this scale. We present some preliminary results on the low-mass breakdown of NRQCD, in particular the behaviour of QQ̄ and Qq̄ spectra as the b...
متن کاملPushing Software Events to the Hardware Limit
Runtimes and applications that rely heavily on event notifications suffer when such notifications must traverse several layers of processing in software. Many of these layers necessarily exist in order to support a general-purpose, portable kernel architecture, but they introduce unacceptable overheads for demanding, high-performance parallel runtimes. Other overheads can arise out of a mismatc...
