Sobre la estratigrafía de los conglomerados de Campanué (Santa Liestra) y formaciones superiores del Eoceno (extremo occidental de la cuenca Tremp-Graus, Pirineo Central, Provincia de Huesca)

Se pone en evidencia la discordancia de los conglomerados de Campanué y su correlación sincrónica con los movimientos y discurtlancia intraluteciense de Mediano, Asimismo se establece el carácter discordante del Bartoniense inferior (calizas lacustres y lignitos de Capella y Laguarres). Finalmente se precisa la estratigrafía de los conglomerados de Canipanué y serie eocena superior

Precisiones sobre la "mise en place" del manto de Gavarnie en el borde norte del valle del Ebro (Región de Barbastro, provincia de Huesca)

La presencia de una ruptura sedimentaria materializada por una brecha poligénica entre la formación de Peraltilla y los yesos de Barbastro, unido al contexto general de los conocimientos regionales actuales, sitúan la "mise en place" del manto de Gavarnie (o fase Pirenaica mayor) como posteriora la deposición de los yesos y anterior a la formación de Peraltilla. En consecuencia los yesos de Barbastro no serían oligocenos sino de una edad comparable, al menos en parte, a las sales potásicas de Cataluña, es decir, Eoceno superior

QCD-Thermodynamics using 5-dim Gravity

We calculate the critical temperature and free energy of the gluon plasma using the dilaton potential arXiv:0911.0627[hep-ph] in the gravity theory of AdS/QCD. The finite temperature observables are calculated in two ways: first, from the Page-Hawking computation of the free energy, and secondly using the Bekenstein-Hawking proportionality of the entropy with the area of the horizon. Renormalization is well defined, because the T=0 theory has asymptotic freedom. We further investigate the change of the critical temperature with the number of flavours induced by the change of the running coupling constant in the quenched theory. The finite temperature behaviour of the speed of sound, spatial string tension and vacuum expectation value of the Polyakov loop follow from the corresponding string theory in AdS_5.Comment: 38 pages, 12 figure

The use of pedicled buccal fat pad combined with sequestrectomy in bisphosphonate-related osteonecrosis of the maxilla

The use of pedicled buccal fat pad flap (BFP) has proved of value for the closure of oroantral and oronasal communications and is a well-established tool in oral and maxillofacial surgery. Otherwise, the perceived limitations of surgical therapy for bisphosphonate-related osteonecrosis of the jaws (BRONJ) have been widely discussed, and recommendations have largely been made to offer aggressive surgery only to stage 3 patients refractary to conservative management. Oroantral communication may be a common complication after sequestrectomy and bone debridement in upper maxillary BRONJ. We report a case series of stage 3 recalcitrant maxillary BRONJ surgically treated with extensive sequestrectomy and first reconstruction using pedicled BFP. All the cases presented an uneventful postoperative healing was uneventful without dehiscence, infection, necrosis or oroantral communication. We postulate that managing initially the site with BFP and primary closure may ensure a sufficient blood supply and adequate protection for an effective bone-healing response to occur. This technique may represent a mechanic protection and an abundant source of adipose-derived adult stem cells after debridement in upper maxillary BRONJ. We evaluate in this work results, advantages and indications of this technique. © Medicina Oral S. L

Drell-Yan bounds on gapped continuum spectra

Theories with gapped continuum spectra have gotten some attention, either as pure 4D models like unparticles, or in 5D realizations as certain soft walls constructions. In this paper, we derive experimental bounds from Drell-Yan processes (pp → ℓ+ℓ−, pp → ℓ±ν) in a particular scenario where the electroweak bosons propagate in an extra dimension that produces a propagator with a continuum spectrum, on top of the isolated corresponding Standard Model pole. Using current LHC data we put a lower bound on the gap of 4.2 TeV (expected), 6.2 TeV (observed, bins with < 10 events combined) at 95% CL, with some dependence in the observed limit on how low statistics bins are treated. We also study the limits for HL-LHC.Atraccion de Talento program (Modalidad 1) of the Comunidad de Madrid (Spain) 2019-T1/TIC-14019Spanish Research Agency (Agencia Estatal de Investigacion) CEX2020-001007-S PID2021-124704NB-I00MCIN/AEIGerman Research Foundation (DFG) A-FQM-178-UGR18FSE Investing in your futureFEDER/Junta de Andalucia - Consejeria de Economia y Conocimiento FQM-225Junta de Andalucia 2021 SGR 00649Ramon y Cajal Program of the University of GranadaGeneralitat de Catalunya PID2020-115845GB-I00Spanish Government PHY-2112540National Science Foundation (NSF)CERCA program of the Generalitat de CatalunyaConsejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET)ANPCyT PICT 2018-03682 PID2020-114767GB-I00 RYC-2016-20678 PICT-2021-0037

Development and Organization of the Lamprey Telencephalon with Special Reference to the GABAergic System

Lampreys, together with hagfishes, represent the sister group of gnathostome vertebrates. There is an increasing interest for comparing the forebrain organization observed in lampreys and gnathostomes to shed light on vertebrate brain evolution. Within the prosencephalon, there is now a general agreement on the major subdivisions of the lamprey diencephalon; however, the organization of the telencephalon, and particularly its pallial subdivisions, is still a matter of controversy. In this study, recent progress on the development and organization of the lamprey telencephalon is reviewed, with particular emphasis on the GABA immunoreactive cell populations trying to understand their putative origin. First, we describe some early general cytoarchitectonic events by searching the classical literature as well as our collection of embryonic and prolarval series of hematoxylin-stained sections. Then, we comment on the cell proliferation activity throughout the larval period, followed by a detailed description of the early events on the development of the telencephalic GABAergic system. In this context, lampreys apparently do not possess the same molecularly distinct subdivisions of the gnathostome basal telencephalon because of the absence of a Nkx2.1-expressing domain in the developing subpallium; a fact that has been related to the absence of a medial ganglionic eminence as well as of its derived nucleus in gnathostomes, the pallidum. Therefore, these data raise interesting questions such as whether or not a different mechanism to specify telencephalic GABAergic neurons exists in lampreys or what are their migration pathways. Finally, we summarize the organization of the adult lamprey telencephalon by analyzing the main proposed conceptions, including the available data on the expression pattern of some developmental regulatory genes which are of importance for building its adult shape

Flexible and Robust Privacy-Preserving Implicit Authentication

Implicit authentication consists of a server authenticating a user based on the user's usage profile, instead of/in addition to relying on something the user explicitly knows (passwords, private keys, etc.). While implicit authentication makes identity theft by third parties more difficult, it requires the server to learn and store the user's usage profile. Recently, the first privacy-preserving implicit authentication system was presented, in which the server does not learn the user's profile. It uses an ad hoc two-party computation protocol to compare the user's fresh sampled features against an encrypted stored user's profile. The protocol requires storing the usage profile and comparing against it using two different cryptosystems, one of them order-preserving; furthermore, features must be numerical. We present here a simpler protocol based on set intersection that has the advantages of: i) requiring only one cryptosystem; ii) not leaking the relative order of fresh feature samples; iii) being able to deal with any type of features (numerical or non-numerical).

Differences between risk perception and risk-taking are related to impulsivity levels

Background Although there is broad agreement that perceived risks determine risk-taking behavior, previous research has shown that this association may not be as straightforward as expected. The main objective of this study was to investigate if the levels of impulsivity can explain part of these controversial findings. Method A total of 1579 participants (Mage = 23.06, from 18 to 60 years; 69.4% women) were assessed for levels of risk perception, risk-taking avoidance, and impulsivity. Results The results showed that while impulsivity was significantly and negatively related to both risk perception and risk-taking avoidance, the relationship with risk-taking avoidance was significantly stronger than with risk perception. The levels of impulsivity predicted risk-taking avoidance even when controlling for risk perception. Conclusions These findings indicate that impulsivity can differentially affect risk perception and risk-taking. We propose that the stronger influence of impulsivity on risk-taking is due to the greater reliance of risk-taking, compared with risk perception, on automatic processes guided by impulses and emotions.Regional Ministry of Economy and Knowledge, Junta de Andalucia UMA18-FEDERJA-13 EMERGIA20_0005
