Development and validation of an Argentine set of facial expressions of emotion
(Taylor & Francis, 2017-02)
Pictures of facial expressions of emotion are used in a wide range of experiments. The last decade has seen an increase in the number of studies presenting local sets of emotion stimuli. However, only a few existing sets ...
Approximating weighted neighborhood independent sets
(Elsevier Science, 2018-02)
A neighborhood independent set (NI-set) is a subset of edges in a graph such that the closed neighborhood of any vertex contains at most one edge of the subset. Finding a maximum cardinality NI-set is an NP-complete problem. ...

Improving dimension estimates for Furstenberg-type sets
(Academic Press Inc Elsevier Science, 2010-01)
In this paper we study the problem of estimating the generalized Hausdorff dimension of Furstenberg sets in the plane. For α ∈ (0, 1], a set F in the plane is said to be an α-Furstenberg set if for each direction e there ...
Salem Sets with No Arithmetic Progressions
(Oxford University Press, 2017-04)
We construct compact Salem sets in R/Z of any dimension (including 1), which do not contain any arithmetic progressions of length 3. Moreover, the sets can be taken to be Ahlfors regular if the dimension is less than 1, ...
Holomorphic functions with large cluster sets
(Wiley VCH Verlag, 2021-05)
We study linear and algebraic structures in sets of bounded holomorphic functions on the ball which have large cluster sets at every possible point (i.e., every point on the sphere in several complex variables and every ...
Some advances on Lovász-Schrijver semidefinite programming relaxations of the fractional stable set polytope
(Elsevier Science, 2014-02)
We study Lovász and Schrijver's hierarchy of relaxations based on positive semidefiniteness constraints derived from the fractional stable set polytope. We show that there are graphs G for which a single application of the ...
