Existence of log canonical closures [PDF]
, 2012 Let $f:X\to U$ be a projective morphism of normal varieties and $(X,\Delta)$ a dlt pair. We prove that if there is an open set $U^0\subset U$, such that $(X,\Delta)\times_U U^0$ has a good minimal model over $U^0$ and the images of all the non-klt ...

On the Existence and Stability of Bulk Nanobubbles.
Langmuir, 2018 Bulk nanobubbles are a novel type of nanoscale bubble system. Because of their extraordinary behavior, however, their existence is not widely accepted.

On the Existence of Simpler Machine Learning Models [PDF]
Conference on Fairness, Accountability and Transparency, 2019 It is almost always easier to find an accurate-but-complex model than an accurate-yet-simple model. Finding optimal, sparse, accurate models of various forms (linear models with integer coefficients, decision sets, rule lists, decision trees) is ...

Taming Existence in RDF Querying [PDF]
, 2008 We introduce the recursive, rule-based RDF query language RDFLog. RDFLog extends previous RDF query languages by arbitrary quantifier alternation: blank nodes may occur in the scope of all, some, or none of the universal variables of a rule.

Existence of moduli spaces for algebraic stacks [PDF]
Inventiones Mathematicae, 2018 We provide necessary and sufficient conditions for when an algebraic stack admits a good moduli space and prove a semistable reduction theorem for points of algebraic stacks equipped with a Θ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage ...

Asymmetries in the Value of Existence [PDF]
, 2019 According to asymmetric comparativism, it is worse for a person to exist with a miserable life than not to exist, but it is not better for a person to exist with a happy life than not to exist.

Existence of entire radial solutions to a class of quasilinear elliptic equations and systems
Electronic Journal of Qualitative Theory of Differential Equations, 2016 In this paper, by a monotone iterative method and the Arzèla-Ascoli theorem, we obtain the existence of entire positive radial solutions to the following quasilinear elliptic equations \[\operatorname{div}(\phi_1(|\nabla u|) \nabla u)+a_1(|x|) \phi_1 ...
