We categorize the global structure of spherically symmetric static solutions of Einstein SU(2)-Yang Mills equations with positive cosmological constant that are smooth at the origin.

Categorizing numbers into even and odd is an ability held by humans that has recently been found to be also honeybees. We examined whether ants could make such parity discrimination. Working on the species Myrmica sabuleti, we learned of two colonies associate 2 black circles with a reward 5 these absence reward, as well other 3 same cues 4 reward. By collectively testing foragers each colony i...

Humans can categorize objects in complex natural scenes within 100-150 ms. This amazing ability of rapid categorization has motivated many computational models. Most of these models require extensive training to obtain a decision boundary in a very high dimensional (e.g., ∼6,000 in a leading model) feature space and often categorize objects in natural scenes by categorizing the context that co-...

One of the most important attributes of cognitive activities in both human and nonhuman animals is the ability to recognize individual objects and to categorize a variety of objects that share some properties. Wild-living spider monkeys, for example, individually recognize their partners and a large number of other conspecifics quickly and accurately regardless of their highly variable spatial ...
