Embodied Cognition: Looking Inward
The body is a highly complex, coordinated system engaged in coping
with many environmental problems. It can be considered as some sort of
opportunity or obstacle, with which internal processing must deal.
Internal processing must take into account the possibilities and
limitations of the particular body. In other words, even if the body is not
involved in the realization of some cognitive explicit task, it is not a
neutral factor of our understanding of why a system solves a task in one
way or another. Therefore, when conducting research on embodiment
and the body’s cognitive system we should not neglect internal, cognitive
processing.
I appeal to Goldman’s research on embodied cognition to sketch
the broader framework for internal processing in embodied cognition. I
believe that even if we don’t accept Goldman’s approach as the viable
proposal for embodied cognition in general, it’s a quite natural starting
point for our analysis. Goldman (2012; 2014, and with de Vignemont
2009) argue for the essential role of the bodily formats or bodily codes
(respectively: B-formats and B-codes) in embodied cognition. B-codes
are here described as the processing of regions or sub-regions of the
central nervous system. They are primarily employed for body control or
monitoring, and reused for cognitive tasks. Beyond doubt, this
conception provides an excellent starting point for analyzing the internal
(mostly neural) processing in cases of embodied cognition.
At the end of this paper, I will argue that the embodiment of
cognition needs a conceptual twist. Following Keijzer’s (2015) interest in
the evolution of the nervous system, and the minimal forms of cognition,
I argue that in investigating embodied cognition, we should investigate
the role played by cognitive processing for specific kinds of organisms,
meaning organisms with a body of a particular morphology (size, shape,
kinds, and distribution of sensors and effectors). Doing that, I refer to
some conceptual and empirical considerations. I will also try to show
that research on embodied cognition is still not sufficiently anchored in
evolutionary and comparative studies on cognition, nor on the nervous
system and body morphology. Bigger reliance on these kinds of studies, will make it make possible to gain a deeper understanding of internal
processing in embodied cognition.Publikacja została sfinansowana ze środków Ministerstwa Nauki i Szkolnictwa Wyższego w ramach programu Narodowego Programu Rozwoju Humanistyki przyznanych na podstawie decyzji 0014/NPRH4/H3b/83/2016 - projekt „Przygotowanie i publikacja dwóch anglojęzycznych numerów monograficznych Internetowego Magazynu Filozoficznego HYBRIS” (3bH 15 0014 83)

Processes at High Energy pp Colliders
In this note we investigate the production of charged heavy particles via
\gaga\ fusion at high energy pp colliders. We revise previous claims that the
\gaga\ cross section is comparable to or larger than that for the corresponding
Drell-Yan process at high energies. Indeed we find that the \gaga\ contribution
to the total production cross section at pp is far below the Drell-Yan cross
section. As far as the individual elastic, semi-elastic and inelastic
contributions to the \gaga\ process are concerned we find that they are all of
the same order of magnitude.Comment: REVTEX, 12 pages, two uuencoded figures appended at the end of the

Improving bounds on flavor changing vertices in the two Higgs doublet model from mixing
We find some constraints on the flavor changing vertices of the two Higgs
doublet model, from the \Delta M_{B_{d}} measurement. Although bounds from this
observable have already been considered, this paper takes into account the role
of a new operator not included previously, as well as the vertices \xi_{bb},
\xi_{tc} and \xi_{sb}. Using the Cheng-Sher parametrization, we found that for
a relatively light charged Higgs boson (200-300 GeV), we get that \lambda
_{tt}<1, while the parameter \lambda_{bb} could have values up to about 50. In
addition, we use bounds for \lambda_{tt} and \lambda_{bb} obtained from
B^{0}->X_{s}\gamma at next to leading order, and studied the case where the
only vanishing vertex factors are the ones involving quarks from the first
family. We obtained that \Delta M_{B_{d}} is not sensitive to the change of the
parameter \lambda_{sb}, while \lambda_{tc}<1Comment: 4 pages, 1 figure, LaTeX2
Flavor changing neutral currents from lepton and B decays in the two Higgs doublet model
Constraints on the whole spectrum of lepton flavor violating vertices are
shown in the context of the standard two Higgs doublet model. The vertex
involving the mixing is much more constrained than the others, and
the decays proportional to such vertex are usually very supressed. On the other
hand, bounds on the quark sector are obtained from leptonic decays of the
mesons and from . We emphasize that
although the mixing restricts severely the
mixing vertex, the upper bound for this vertex could still give a sizeable
contribution to the decay respect to the standard
model contribution, from which we see that such vertex could still play a role
in the phenomenology.Comment: 9 pages, 2 figures, LaTeX2e. Minor typos corrected. References added

No classical limit of quantum decay for broad states
Though the classical treatment of spontaneous decay leads to an exponential
decay law, it is well known that this is an approximation of the quantum
mechanical result which is a non-exponential at very small and large times for
narrow states. The non exponential nature at large times is however hard to
establish from experiments. A method to recover the time evolution of unstable
states from a parametrization of the amplitude fitted to data is presented. We
apply the method to a realistic example of a very broad state, the sigma meson
and reveal that an exponential decay is not a valid approximation at any time
for this state. This example derived from experiment, shows the unique nature
of broad resonances
The Cop Number of the One-Cop-Moves Game on Planar Graphs
Cops and robbers is a vertex-pursuit game played on graphs. In the classical
cops-and-robbers game, a set of cops and a robber occupy the vertices of the
graph and move alternately along the graph's edges with perfect information
about each other's positions. If a cop eventually occupies the same vertex as
the robber, then the cops win; the robber wins if she can indefinitely evade
capture. Aigner and Frommer established that in every connected planar graph,
three cops are sufficient to capture a single robber. In this paper, we
consider a recently studied variant of the cops-and-robbers game, alternately
called the one-active-cop game, one-cop-moves game or the lazy-cops-and-robbers
game, where at most one cop can move during any round. We show that Aigner and
Frommer's result does not generalise to this game variant by constructing a
connected planar graph on which a robber can indefinitely evade three cops in
the one-cop-moves game. This answers a question recently raised by Sullivan,
Townsend and Werzanski.Comment: 32 page
Uncovering hidden modes in RR Lyrae stars
The Kepler space telescope revealed new, unexpected phenomena in RR Lyrae
stars: period doubling and the possible presence of additional modes.
Identifying these modes is complicated because they blend in the rich features
of the Fourier-spectrum. Our hydrodynamic calculations uncovered that a
'hidden' mode, the 9th overtone is involved in the period doubling phenomenon.
The period of the overtone changes by up to 10 per cent compared to the linear
value, indicating a very significant nonlinear period shift caused by its
resonance with the fundamental mode. The observations also revealed weak peaks
that may correspond to the first or second overtones. These additional modes
are often coupled with period doubling. We investigated the possibilities and
occurrences of mutual resonances between the fundamental mode and multiple
overtones in our models. These theoretical findings can help interpreting the
origin and nature of the 'hidden' modes may be found in the high quality light
curves of space observatories.Comment: In proceedings of "20th Stellar Pulsation Conference Series: Impact
