Aims. We searched for very high energy (VHE) γ-ray emission from the supernova remnant Cassiopeia A Methods. The shell-type supernova remnant Cassiopeia A was observed with the 17 meter MAGIC telescope between July 2006 and January 2007 for a total time of 47 hours. Results. The source was detected above an energy of 250 GeV with a significance of 5.2 σ and a photon flux above 1 TeV of (7.3±0.7...

Various studies have reported the physical and mental health benefits from exposure to "green" neighborhoods, such as proximity to neighborhoods with trees and vegetation. However, no studies have explicitly assessed the association between exposure to "green" surroundings and cognitive function in terms of student academic performance. This study investigated the association between the "green...

We investigate the problem of automatically labelling appearances of characters in TV or film material with their names. This is tremendously challenging due to the huge variation in imaged appearance of each character and the weakness and ambiguity of available annotation. However, we demonstrate that high precision can be achieved by combining multiple sources of information, both visual and ...

Karbon monoksida merupakan salah satu jenis polutan udara yang berada di lingkungan sekitar kita. Jika karbon masuk ke dalam tubuh manusia, maka akan mengikat sel darah merah 200 hingga 250 kali lebih kuat dibandingkan dengan oksigen, sehingga menggantikan peran oksigen dan membentuk senyawa kimia Karboksi Hemoglobin (COHb). Sebagai upaya memperkecil resiko dari keracunan dibutuhkan sistem dapa...

in order to evaluation of plant densities and row spacing effects on growth and yield of wheat, an experiment was conducted by using four plant densities (125, 250, 375 and 500 plants per m2),two row spacing (12.5 and 25 cm), in a randomized complete block design with three replicates in anbare-ololum reign in rainfed and saline conditions during 2008-2009. results showed that leaf area index (...

OBJECTIVE To verify the usefulness of the BiliCheck transcutaneous bilirubin meter as a screening device for neonatal jaundice in a Chinese population compared with the Minolta bilirubin meter. DESIGN A prospective correlation study that compared transcutaneous bilirubin measurements with serum bilirubin levels. SETTING Obstetric ward and a neonatal unit of a regional hospital in Hong Kong....

1. Drawing balls without replacement (20 pts). Suppose that we have an urn containing one red ball and n − 1 white balls. Each time we draw a ball at random from the urn without replacement (so after the n-th drawing, there is no ball left in the urn). X i = 1 if the i-th ball is red, 0 otherwise.
