Large volumes of electronic health records, including free-text documents, are extensively generated within various sectors of healthcare. Medical concept annotation systems are designed to enrich these documents with key concepts in the domain using reference terminologies. Although there is a wide range of annotation systems, there is a lack of comparative analysis that enables thorough under...

Land cover type is a crucial parameter that is required for various land surface models that simulate water and carbon cycles, ecosystem dynamics, and climate change. Many land use/land cover maps used in recent years have been derived from field investigations and remote-sensing observations. However, no land cover map that is derived from a single source (such as satellite observation) proper...

We characterize a general solution to the vacuum Einstein equations which admits isolated horizons. We show it is a non-linear superposition – in precise sense – of the Schwarzschild metric with a certain free data set propagating tangentially to the horizon. This proves Ashtekar’s conjecture about the structure of spacetime near the isolated horizon. The same superposition method applied to th...

We provide a Hilbert-Mumford Criterion for the action of a reductive group G on a Q-factorial algebraic variety X, partially proving a conjecture stated by A. BiaÃlynicki-Birula. The result allows to construct G-invariant open subsets of X admitting a good quotient by G from certain open subsets admitting a good quotient by a maximal torus T of G. As an application, we indicate an explicit meth...

We compute all the simply connected homogeneous and infinitesimally surfaces admitting one or more invariant affine connections. find exactly six non equivalent than connections four classes of connection.

Energy usage of large-scale data centers has become a major concern for cloud providers. There has been an active effort in techniques for the minimization of the energy consumed in the data centers. However, most approaches lack the analysis and application of real cloud backend traces. In existing approaches, the variation of cloud workloads and its effect on the performance of the solutions ...

An edge network deployment consists of many (tens to a few hundred) satellite data centers. To optimize enduser perceived performance, a Global Traffic Management (GTM) solution needs to continuously monitor the performance between the users and the data centers, in order to dynamically select the “best” data center for each user. Though widely adopted in practice, GTM solutions based on active...
