Little is known about how individuals come to relate to settings in virtual worlds (VWs), which are defined as digital environments in which individuals, groups, and even organizations interact in virtual (that is to say, nonphysical) spaces. This research develops a theory of virtual space and place (VSP), specifically relating this to the setting of Second Life (SL), a prominent social virtua...

Let P be a class of Banach spaces and let T = {Tα}α∈A be a set of metric spaces. We say that T is a set of test-spaces for P if the following two conditions are equivalent: (1) X / ∈ P; (2) The spaces {Tα}α∈A admit uniformly bilipschitz embeddings into X. The first part of the paper is devoted to a simplification of the proof of the following test-space characterization obtained in M. I. Ostrov...

We introduce the Banach space S0 ⊆ L 2 which has a variety of properties making it a useful tool in Gabor analysis. S0 can be characterized as the smallest time-frequency homogeneous Banach space of (continuous) functions. We also present other characterizations of S0 turning it into a very flexible tool for Gabor analysis and allowing for simplifications of various proofs. A careful analysis o...

Many built-in self-testing (BIST) schemes compress the test responses from a k-output circuit to q signature streams, where q << k, a process termed space compaction. The effectiveness of such a compaction method can be measured by its compaction ratio c = k/q. A high compaction ratio can introduce aliasing, which occurs when a faulty test response maps to the faultfree signature. We investigat...

Little is known about how individuals come to relate to settings in virtual worlds (VWs), which are defined as 18 digital environments in which individuals, groups, and even organizations interact in virtual (that is to say, 19 nonphysical) spaces. This research develops a theory of virtual space and place (VSP), specifically relating 20 this to the setting of Second Life (SL), a prominent soci...

Abstract: It is proven that the ⋆-product of field operators implies that the space of test functions in the Wightman approach to noncommutative quantum field theory is one of the Gel’fand-Shilov spaces S with β < 1/2. This class of test functions smears the noncommutative Wightman functions, which are in this case generalized distributions, sometimes called hyperfunctions. The existence and de...

This paper studies the problem of implementing a shared memory test-and-set object using only shared registers. Our contribution is threefold. First, we present a general framework to allow reasoning about reusing one-shot shared memory objects in the construction of bounded space long-lived objects. Then we derive general theorems about test-andset objects that simplifies reasoning about their...

introduction: lipomas of the larynx are very rare benign lesions; macroscopically, they resemble retention cysts, so their diagnosis is usually made after surgery.   case report: a rare case of pediatric paraglottic space lipoma in an 11-year-old boy is explained. the mass was mobile, soft, without fluctuation or pulsation. ct scan revealed a 5.7 cm cervical fat density with regional lymphadeno...
