When parallel applications are run in large-scale distributed environments, such as grids, peer-to-peer (P2P) systems, and clouds, the set of resources used can change dynamically as machines crash, reservations end, and new resources become available. It is vital for applications to respond to these changes. Therefore, it is necessary to keep track of the available resources—a problem which is...

With the advent of high-quality surveys in cosmology the full three-point correlation function will be a valuable statistic for describing structure formation models. It contains information on cosmological parameters and detailed halo properties that cannot be extracted from the two-point correlation function. We use the halo clustering model to analytically calculate the three-point correlati...

1930 yılından günümüze uzanan aerojeller; Guinness rekorlar kitabına giren en hafif ve katı malzeme olarak seçilmiştir. Yüksek ısıl absorbsiyon özelliği, çok iyi yalıtkanlık kabiliyeti, mezo gözenek yapısı mukavemetinin yüzey alanının yüksek olması gibi üstünlüklerinin birçok malzemeye alternatif kullanım avantajı sektörde olanağı sunmaktadır. Bu çalışmada, sol-jel tekniği kullanılarak saflıkta...

Összefoglaló. Egy 47 éves nőbeteg tranziens ST-eleváció miatt került felvételre és coronarographiára. A ST-elevációnak véleményezett elektrokardiogram poroszsisak-jelnek felelt meg, amelyet egy EKG-műtermék okozott. Habár a számtalan, nem coronariaeredetű oka ismert, műtermék okozta poroszsisak-jelet még ismertettek. Fontos felismerése felesleges diagnosztikai terápiás beavatkozások elkerülése ...
