Open AccessUpdated Design of the CMB Polarization Experiment Satellite LiteBIRD
Recent developments of transition-edge sensors (TESs), based on extensive experience in ground-based experiments, have been making the sensor techniques mature enough for their application on future satellite ...

SIRT1 promotes thyroid carcinogenesis driven by PTEN deficiency
Current genetic evidence in mice indicates that SIRT1 has potent tumor suppressor activity in a variety of cancer models, with no evidence yet for SIRT1 oncogenic activity in vivo. We report here that transgenic

SIRT1 stabilizes PML promoting its sumoylation
SIRT1, the closest mammalian homolog of yeast Sir2, is an NAD+-dependent deacetylase with relevant functions in cancer, aging, and metabolism among other processes. SIRT1 has a diffuse nuclear localization but is...

Open AccessSeparation of Correlated Astrophysical Sources Using Multiple-Lag Data Covariance Matrices
This paper proposes a new strategy to separate astrophysical sources that are mutually correlated. This strategy is based on second-order statistics and exploits prior information about the possible structure ...

Open AccessDetection of Point Sources on Two-Dimensional Images Based on Peaks
This paper considers the detection of point sources in two-dimensional astronomical images. The detection scheme we propose is based on peak statistics. We discuss the example of the detection of far galaxies ...

Point Source Detection on the Sphere Using Wavelets and Optimal Filters
We present an analysis of simulated microwave data to detect point sources using wavelets and optimal filters. We search for point sources in the Time Order Data (TOD), using optimal adaptive filters, and in t...
