Maximally selected chi-square statistics and binary splits of nominal variables [PDF]

open access: yes, 2005
We address the problem of maximally selected chi-square statistics in the case of a binary Y variable and a nominal X variable with several categories. The distribution of the maximally selected chi-square statistic has already been derived when the best

Stone-Type Dualities for Separation Logics [PDF]

open access: yesLogical Methods in Computer Science, 2019
Stone-type duality theorems, which relate algebraic and relational/topological models, are important tools in logic because -- in addition to elegant abstraction -- they strengthen soundness and completeness to a categorical equivalence, yielding a ...

The Black Hole Mass Scale of Classical and Pseudo Bulges in Active Galaxies

open access: yes, 2014
The mass estimator used to calculate black hole (BH) masses in broad-line active galactic nuclei (AGNs) relies on a virial coefficient (the "$f$ factor") that is determined by comparing reverberation-mapped (RM) AGNs with measured bulge stellar velocity ...

Psi-Calculi Revisited: Connectivity and Compositionality [PDF]

open access: yesLogical Methods in Computer Science, 2020
Psi-calculi is a parametric framework for process calculi similar to popular pi-calculus extensions such as the explicit fusion calculus, the applied pi-calculus and the spi calculus.

Dualized Simple Type Theory [PDF]

open access: yesLogical Methods in Computer Science, 2017
We propose a new bi-intuitionistic type theory called Dualized Type Theory (DTT). It is a simple type theory with perfect intuitionistic duality, and corresponds to a single-sided polarized sequent calculus.

Slice & Dice: Identifying and Removing Bright Galactic Binaries from LISA Data [PDF]

open access: yes, 2006
Here we describe a hierarchal and iterative data analysis algorithm used for searching, characterizing, and removing bright, monochromatic binaries from the Laser Interferometer Space Antenna (LISA) data streams.

On the characterization of models of H*: The semantical aspect [PDF]

open access: yesLogical Methods in Computer Science, 2016
We give a characterization, with respect to a large class of models of untyped lambda-calculus, of those models that are fully abstract for head-normalization, i.e., whose equational theory is H* (observations for head normalization).

Experimental high-dimensional two-photon entanglement and violations of generalised Bell inequalities

open access: yes, 2011
Quantum entanglement plays a vital role in many quantum information and communication tasks. Entangled states of higher dimensional systems are of great interest due to the extended possibilities they provide.

Yang-Mills Integrals [PDF]

open access: yes, 2001
Two results are presented for reduced Yang-Mills integrals with different symmetry groups and dimensions: the first is a compact integral representation in terms of the relevant variables of the integral, the second is a method to analytically evaluate ...

Generic Fibrational Induction [PDF]

open access: yesLogical Methods in Computer Science, 2012
This paper provides an induction rule that can be used to prove properties of data structures whose types are inductive, i.e., are carriers of initial algebras of functors.
