Thermal facial reactivity patterns predict social categorization bias triggered by unconscious and conscious emotional stimuli [PDF]

open access: yes, 2017
Members of highly social species decode, interpret, and react to the emotion of a conspecific depending on whether the other belongs to the same (ingroup) or different (outgroup) social group.

State maps on semihoops

open access: yesOpen Mathematics, 2018
In this paper, we introduce the notion of state maps from a semihoop H1 to another semihoop H2, which is a generalization of internal states (or state operators) on a semihoop H.

Homomorphisms on infinite direct products of groups, rings and monoids [PDF]

open access: yes, 2014
We study properties of a group, abelian group, ring, or monoid $B$ which (a) guarantee that every homomorphism from an infinite direct product $\prod_I A_i$ of objects of the same sort onto $B$ factors through the direct product of finitely many ...

Regularized sampling of multiband signals [PDF]

open access: yes, 2010
This paper presents a regularized sampling method for multiband signals, that makes it possible to approach the Landau limit, while keeping the sensitivity to noise at a low level.

The Universal Theory of First Order Algebras and Various Reducts [PDF]

open access: yes, 2015
First order formulas in a relational signature can be considered as operations on the relations of an underlying set, giving rise to multisorted algebras we call first order algebras.

The Booleanization of an inverse semigroup

open access: yes, 2019
We prove that the forgetful functor from the category of Boolean inverse semigroups to inverse semigroups with zero has a left adjoint. This left adjoint is what we term the `Booleanization'.

Clones with finitely many relative R-classes [PDF]

open access: yes, 2010
For each clone C on a set A there is an associated equivalence relation analogous to Green's R-relation, which relates two operations on A iff each one is a substitution instance of the other using operations from C.

Closed-loop Reference Models for Output-Feedback Adaptive Systems

open access: yes, 2012
Closed-loop reference models have recently been proposed for states accessible adaptive systems. They have been shown to have improved transient response over their open loop counter parts. The results in the states accessible case are extended to single

On Congruence Compact Monoids [PDF]

open access: yes, 1999
A universal algebra is called congruence compact if every family of congruence classes with the finite intersection property has a non-empty intersection.

Long-term stability of fibre-optic transmission for multi-object spectroscopy

open access: yes, 2012
We present an analysis of the long-term stability of fibre-optic transmission properties for fibre optics in astronomy. Data from six years of operation of the AAOmega multi-object spectrograph at the Anglo-Australian Telescope is presented.
