Existence of Equilibrium in Common Agency Games with Adverse Selection
We establish the existence of sequential equilibria in general menu games, known to be su±cient to analyze common agency problems. In particular, we show that our result solves some unpleasant features of early approaches.
Tau Custodian searches at the LHC
The tau lepton can be more composite than naively expected in models of
strong electroweak symmetry breaking with tri-bimaximal lepton mixing. New
leptonic resonances required by custodial symmetry, the tau custodians, can
then be the first signal of this lepton flavor realization. Tau custodians can
be very light, decaying almost exclusively into taus. The LHC reach for these
new leptons is up to masses of 240, 480 and 720 GeV for sqrt{s}=14 TeV and an
integrated luminosity of 30, 300 and 3000 fb^{-1}, respectively. Our analysis
can be extended to any pair produced particles decaying mostly into taus and
Standard Model bosons.Comment: 12 pages, 2 figure
Effective invariants of braid monodromy and topology of plane curves
In this paper we construct effective invariants for braid monodromy of affine
curves. We also prove that, for some curves, braid monodromy determines their
topology. We apply this result to find a pair of curves with conjugate
equations in a number field but which do not admit any orientation-preserving
homeomorphism.Comment: 26 pages, two EPS figures, LaTe
Gluon excitations in t tbar production at hadron colliders
We argue that a relatively light massive gluon with mass <= 1 TeV, small
purely axial couplings to light quarks and sizable vector and axial couplings
to the top quark can reproduce the large forward-backward asymmetry observed at
the Tevatron without conflicting with the t tbar and the dijet invariant mass
distributions measured at the Tevatron and the LHC. We show that realistic
Higgsless models with warped extra dimensions naturally fulfil all the
necessary ingredients to realize this scenario. While current data is unable to
discover or exclude these heavy gluons with masses 850 GeV, they should be
observed at the (7 TeV) LHC with a luminosity of the order of 300 pb^{-1}.Comment: 16 pages, 6 figure
Diboson resonant production in non-custodial composite Higgs models
We show that the recently reported excess in resonant diboson production can
be explained in the context of non-custodial composite Higgs models. Dibosons
are generated via the s-channel exchange of massive vector bosons present in
these models. We discuss the compatibility of the signal excess with other
diboson experimental searches. We also discuss the tension between diboson
production and other experimental tests of the model that include electroweak
precision data, dilepton, dijet and top pair production and show that there is
a region of parameter space in which they are all compatible with the excess.Comment: 15 pages, 2 figure
Essential coordinate components of characteristic varieties
In this note we give an algebraic and topological interpretation of essential

Proteomic analysis in wild type and cisplatin resistant yeast strain of saccharomyces cerevisiae
Research carried out in oncology has allowed the identification and characterization of molecular markers of resistance to antineoplastic drugs. It supposes a great advance and allows the administration of customized chemotherapies to patients.
The aim of this work is to carry out a proteomic analysis in the wild type strain and cisplatin resistant strain of Saccharomyces cerevisiae in order to look for possible markers of resistance, as well as the mechanisms involved.Universidad de Málaga.

One hundred of cells generations connect the resistance to drugs and the replicative aging mechanisms
There are researchs that reveal a relationship between acquired resistance to antineoplastic drugs and aging.
Therefore, the identification of genes involved in senescence could have a potential therapeutic utility for the prediction and/or prevention of resistance to antineoplastic drugs.
The aim of this work is to study the relationship between replicative aging and acquired resistance to Cisplatin and Bleomycin in the yeast Saccharomyces cerevisiae.Universidad de Málaga. Campus de Excelencia Internacional AndalucĂa Tech
Learning-Based Adaptation for Personalized Mobility Assistance
Mobility assistance is of key importance for people with disabilities to remain autonomous in their preferred environments. In severe cases, assistance can be provided by robotized wheelchairs that can perform complex maneuvers and/or correct the user’s commands. User’s acceptance is of key importance, as some users do not like their commands to be modified. This work presents a solution to improve acceptance. It consists of making the robot learn how the user drives so corrections will not be so noticeable to the user. Case Based Reasoning (CBR) is used to acquire a user’s driving model reactive level. Experiments with volunteers at Fondazione Santa Lucia (FSL) have proven that, indeed, this customized approach at assistance increases acceptance by the user.This work has been partially supported by the Spanish Ministerio de Educacion y Ciencia (MEC), Project TEC2011-29106-C02-01. The authors would like to thank Santa Lucia Hospedale and all volunteers for their kind cooperation and Sauer Medica for providing the power wheelchair
New markers of bleomycin resistance
Resistance to chemotherapy is one of the main problems of this type of therapy. Studies carried out determine the usefulness of predictive biomarkers to improve this treatment.
