In a seminal STOC’95 paper, Arya et al. conjectured that spanners for low-dimensional Euclidean spaces with constant maximum degree, hop-diameter O(logn) and lightness O(logn) (i.e., weight O(logn)· w(MST)) can be constructed in O(n logn) time. This conjecture, which became a central open question in this area, was resolved in the affirmative by Elkin and Solomon in STOC’13 (even for doubling m...

It has recently been demonstrated that a lateralized distractor that matches the individual's top-down control settings elicits an N2pc wave, an electrophysiological index of the focus of visual-spatial attention, indicating that contingent capture has a visual-spatial locus. Here, we investigated whether contingent capture required capacity-limited central resources by incorporating a continge...

It is widely acknowledged that visual input is processed along two anatomically and functionally distinct pathways--a ventral pathway for conscious perception and a dorsal pathway for action control. The present study investigated whether the apparent direct and unmediated processing in the dorsal stream is subject to capacity limitations. Specifically, we tested whether a simple dorsal task of...

due to structural characteristics and spiritual concepts which are latent inside iranian gardens, it has always drawn attention of domestic and foreign researchers and one of the objectives of these researchers was an attempt to achieve historical garden model in iran which have been modified or subjected to decline. the studies, which have been carried out concerning to iranian historical gard...

Historical data items are often semantically inter-related, such as news events that build on past events. Such inter-related data have so far been visualized primarily with simple timeline interfaces, which tend to not scale well, and which do not illustrate important semantic relationships among the data. An improved technique would be useful in news analysis, social and historical research, ...

A key concept is a description of course content knowledge particular to a given historical period. The key concepts and content outlines that follow provide a conceptual framework to help teachers and students understand, organize and prioritize historical developments within each designated historical period. It is not necessary to teach the concepts in the order listed in these outlines, or ...
