Forum of Mathematics, Sigma, 2022 This is the first of a series of papers concerning what might be thought of as ‘locally grouped spaces’, in a loose analogy with the locally ringed spaces of algebraic geometry. The spaces that we have in mind are simplicial sets that generalise the simplicial sets that underlie and determine the classifying spaces of finite (or compact) groups. If the

On Path Integral Localization and the Laplacian
, 1998 We introduce a new localization principle which is a generalized canonical transformation. It unifies BRST localization, the non-abelian localization principle and a special case of the conformal Duistermaat-Heckman integration formula of Paniak ...

A direct localization of a fast radio burst and its host [PDF]
Nature, 2017 Fast radio bursts are astronomical radio flashes of unknown physical nature with durations of milliseconds. Their dispersive arrival times suggest an extragalactic origin and imply radio luminosities that are orders of magnitude larger than those of all ...

Adversarial Complementary Learning for Weakly Supervised Object Localization [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018 In this work, we propose Adversarial Complementary Learning (ACoL) to automatically localize integral objects of semantic interest with weak supervision. We first mathematically prove that class localization maps can be obtained by directly selecting the

A sparse signal reconstruction perspective for source localization with sensor arrays
IEEE Transactions on Signal Processing, 2005 We present a source localization method based on a sparse representation of sensor measurements with an overcomplete basis composed of samples from the array manifold. We enforce sparsity by imposing penalties based on the /spl lscr//sub 1/-norm.

Anderson Localization Phenomenon in One-dimensional Elastic Systems
, 2013 The phenomenon of Anderson localization of waves in elastic systems is studied. We analyze this phenomenon in two different set of systems: disordered linear chains of harmonic oscillators and disordered rods which oscillate with torsional waves.

Dead Reckoning Localization Technique for Mobile Wireless Sensor Networks
, 2015 Localization in wireless sensor networks not only provides a node with its geographical location but also a basic requirement for other applications such as geographical routing. Although a rich literature is available for localization in static WSN, not

Explaining Gabriel-Zisman localization to the computer [PDF]
, 2005 This explains a computer formulation of Gabriel-Zisman localization of categories in the proof assistant Coq. It includes both the general localization construction with the proof of GZ's Lemma 1.2, as well as the construction using calculus of fractions.

Onset of Localization in Heterogeneous Interfacial Failure
, 2012 We study numerically the failure of an interface joining two elastic materials under load using a fiber bundle model connected to an elastic half space.
