[1] An important item to distinguish in estimations of cloud forcing is the characteristics of the ‘‘clear sky.’’ In this study we investigate the influence of the composition of the clear sky in calculations of shortwave cloud forcing based on two case studies from the Monterey Area Ship Track Experiment (MAST). The forcing is calculated with respect to a clear sky devoid of aerosol particles ...

Polarization is the next frontier of cosmic microwave background analysis, but its signal is dominated over much of the sky by foregrounds which must be carefully removed. To determine the efficacy of this cleaning, it is necessary to have sensitive tests for residual foreground contamination in polarization sky maps. The dominant Galactic foregrounds introduce a large-scale anisotropy on to th...

Contrary to the story of the star-counter in Le Petit Prince, there aren’t unnumerable stars in the night sky, at least so far as we can see with our own eyes. Only about a thousand are visible. Almost all have names or Greek letter designations as part of constellations that anyone can learn to recognize. Modern astronomers have divided the sky into 88 constellations, many of them fictitious— ...

Gravitational lensing of the microwave background by the intervening dark matter mainly arises from large-angle fluctuations in the projected gravitational potential and hence offers a unique opportunity to study the physics of the dark sector at large scales. Studies with surveys that cover greater than a percent of the sky will require techniques that incorporate the curvature of the sky. We ...

The detection model of sky polarization based on image as a new navigation technology, has a relatively good stability and high research value. In order to improve the accuracy and reliability of the polarization mode measurement and continuous measurement, it constructs a set device of polarized light detection based on image’s real-time synchronous acquisition. Besides, it has carried on the ...

Abstract. All-sky cameras are frequently used to detect cloud cover; however, this work explores the use of these instruments for more complex purpose extracting relative sky radiances. An all-sky camera (SONA202-NF model) with three colour filters narrower than usual kind is configured capture raw images at seven exposure times. A detailed characterization black level, readout noise, hot pixel...

BACKGROUND Surdashan Kriya Yoga (SKY) is a procedure that in various studies, has shown evidences of efficacy in alleviating Depression and Anxiety disorders, but in Europe and USA it has not been studied yet on a Caucasian population as an adjunct therapy for psychiatric Disorders. METHODS The study involved a sample of consenting women and men (n = 69) who received SKY therapy for a six-mon...

The hard x-ray (10-600 keV) sky is inherently time variable and yet has neither been surveyed nor been monitored with a sensitive imaging telescope. The Energetic X-ray Imaging Survey Telescope (EXIST) is a mission concept, proposed for MIDEX, which would conduct the first imaging all-sky hard x-ray survey as well as provide a sensitive all sky monitor (ASM). With ∼60% sky coverage each orbit, ...
