A branch-and-cut algorithm for the routing and spectrum allocation problem
(Universidad Torcuato Di Tella, 2023)
One of the most promising solutions to deal with huge data traffic demands in
large communication networks is given by flexible optical networking, in particular
the flexible grid (flexgrid) technology specified in the ...
An integer programming approach for the hyper-rectangular clustering problem with axis-parallel clusters and outliers
(Universidad Torcuato Di Tella, 2023)
We present a mixed integer programming formulation for the problem of clustering
a set of points in Rd with axis-parallel clusters, while allowing to discard a pre-specified
number of points, thus declared to be outliers. ...
Valid inequalities and complete characterizations of the 2-domination and P3-hull number polytope
(Universidad Torcuato Di Tella, 2023)
Given a graph G = (V;E), a subset S V is 2-dominating if every vertex in S
has at least two neighbors in S. The minimum cardinality of such a set is called
the 2-domination number of G. Consider a process in discrete ...
Peer tutoring of computer programming increases exploratory behavior in children
(Journal of Experimental Child Psychology, 2022)
There is growing interest in teaching computer science and programming
skills in schools. Here we investigated the efficacy of
peer tutoring, which is known to be a useful educational resource
in other domains but never ...

(2022)
Objective. To assess whether the introduction of comprehensive smoke-free legislation affected tourism in four Caribbean Community (CARICOM) countries – Barbados, Guyana, Jamaica, and Trinidad and Tobago. Methods. We ...
Equilibrium and Real Options in the Ethanol Industry: Modelling and Empirical Evidence
(Journal of Commodity MarketsElsevier B.V., 2022)
In the last twenty years a large number of competitive ethanol rms have estab-
lished operations in the US. Ethanol, produced from corn, is blended with pure
gasoline to produce fuel. Producers hold an option to turn o ...
Exploiting user-frequency information for mining regionalisms in Argentinian Spanish from Twitter
(Procesamiento del Lenguaje Natural, Revista, 2022)
The task of detecting regionalisms (expressions or words used in certain
regions) has traditionally relied on the use of questionnaires and surveys, heavily
depending on the expertise and intuition of the surveyor. The ...
Working Memory for Spatial Sequences: Developmental and Evolutionary Factors in Encoding Ordinal and Relational Structures
(Journal of Neuroscience, 2022)
Sequence learning is a ubiquitous facet of human and animal cognition. Here, using a common sequence reproduction task,
we investigated whether and how the ordinal and relational structures linking consecutive elements ...
Imagetic and affective measures of memory reverberation diverge at sleep onset in association with theta rhythm
(Elsevier Inc, 2022)
The ‘day residue’ - the presence of waking memories into dreams - is a century-old concept that remains controver-
sial in neuroscience. Even at the psychological level, it remains unclear how waking imagery cedes into ...
Chronotype at the beginning of secondary school and school timing are both associated with chronotype development during adolescence
(Scientific Reports, 2022)
The misalignment between late chronotypes and early school start times affect health, performance and psychological well-being of adolescents. Here we test whether, and how, the baseline chronotype (i.e. chronotype at the ...
