Entanglement susceptibility: Area laws and beyond
Generic quantum states in the Hilbert space of a many body system are nearly
maximally entangled whereas low energy physical states are not; the so-called
area laws for quantum entanglement are widespread. In this paper we introduce
the novel concept of entanglement susceptibility by expanding the 2-Renyi
entropy in the boundary couplings. We show how this concept leads to the
emergence of area laws for bi-partite quantum entanglement in systems ruled by
local gapped Hamiltonians. Entanglement susceptibility also captures
quantitatively which violations one should expect when the system becomes
gapless. We also discuss an exact series expansion of the 2-Renyi entanglement
entropy in terms of connected correlation functions of a boundary term. This is
obtained by identifying Renyi entropy with ground state fidelity in a doubled
and twisted theory.Comment: minor corrections, references adde
Executive functions in universal design for learning: moving towards inclusive education
This article partially introduces and analyses the results of a project funded by the Spanish Ministry of Science and Innovations regarding the âApplication of Universal Design for Learning by means of the use of digitally accessible materials: implications for literacy in Primary Education and teacher education-DUALECTICâ(Ref. EDU2011-24926), within the National R+D+I Plan 2008â 2011. Sub-programme of Fundamental Research Projects 2011-2014The aim of this study is to understand the way in which executive functions are promoted in students by analyzing the Universal Design for Learning (UDL) principles, guidelines and checkpoints. After having performed a content analysis of such material, the results show that a little over half of the 31 checkpoints address the 12 executive functions being considered, the most prominent being: feedback response, planning, metacognition and organisation. Among the three brain networks represented in UDL, in particular, cognitive control has a more relevant presence in the strategic and affective networks, which indicates the importance given to teachers promoting that students learn how to anticipate, structure and decide their learning actions, and how students can rebuild their experience and learning, through reflection, revision and improvement processes. It is concluded that UDL not only constitutes a framework that enhances improvement towards barrier elimination to studentsâ learning and participation, but it also provides guidance for classroom practices that can improve the executive ability of students as long as there is encouragement to develop the affective dimension and its internal management within the learning contextMinisterio de Ciencia e InnovaciĂłn.

Development and characterization of an eggplant (Solanum melongena) doubled haploid population and a doubled haploid line with high androgenic response
[EN] We developed an eggplant doubled haploid (DH) population from a commercial hybrid through androgenesis in microspore culture. Morphological variation, reproductive ability and androgenic responsiveness were evaluated. The DH population showed segregation in vegetative traits related to leaf, flower and fruit, and in reproductive traits such as fruit and seed setting or germination rate. The DH population and subsequent generations also presented variation in the androgenic response, with null, low and high response lines. From this population, we were able to identify the first eggplant highly androgenic DH line (DH36), remarkably similar to the donor hybrid in terms of morphology and reproductive ability, but stably producing four times more calli than the hybrid. The segregating DH population is potentially useful for genetic studies and mapping of several traits, whereas the highly androgenic line DH36 may be used as a model line to facilitate the study of eggplant androgenesis and embryogenesis for both basic and applied research.We would like to thank the reviewers of this manuscript for their critical and helpful comments.

Modeling political mimetic isomorphism versus economic and quality factors in local government privatizations
Numerous studies have considered the economic impact and
political influence of privatization. However, the theoretical
approaches previously applied to model privatization,
whether economic or political, have not obtained robust
results. To address this question, we present a new political
approach, based on mimetic isomorphism, which enables us
to more accurately define the relationship between privatization,
political theory and economic aspects. This new focus,
termed political mimetic isomorphism, hypothesizes that the
privatization of public services is influenced by an imitation
effect between neighboring municipalities that share a common
political ideology. In our study, this approach is applied,
using geostatistical tools and logistic regression analysis with
spatial variables, to a sample of municipalities that privatized
their water and/or waste collection services during the
period 2014â2019. The results obtained demonstrate the
validity of the theoretical model of political mimetic isomorphism
and show that this factor exerts a stronger influence
on privatization than certain economic variables.Agencia de InnovaciĂłn y Desarrollo de AndalucĂa, Grant/Award Number: P20_000605Ministerio de Ciencia e InnovaciĂłn, Grant/Award Numbers: PID2021-128713OB-I00, MCIN/AEI/10.13039/501100011033/yporFEDERUnamaneradehacerEuropaUniversidad de Granada, Grant/Award Number: B-SEJ-476-UGR20Funding for openaccess charge, Grant/Award Number: UniversidaddeGranada/CBU

Assessment of a surface-active ionic liquid formulation for EOR applications: Experimental and simulation studies
This study aims to assess a surfactant blend for enhanced oil recovery from carbonate rocks. Due to the abundance of these reservoirs, their profitable exploitation would ensure our petrochemical needs are met, and maintain current quality of life. The objective of this work is to increase the technology readiness level of our previous proposal based on the use of a blend of pure sodium dodecylbenzene sulfonate and the surface-active ionic liquid cocosalkylpentaethoximethyl ammonium methylsulfate. To that aim, the method was adapted for its application with a commercially available petrochemical surfactant (RECOLAS103, a mixture of lineal alkyl benzene sulfonates), and reservoir simulations were carried out to evaluate its effectiveness. Phase behavior, stability, dynamic interfacial tension, adsorption and core flooding were the experimental tests carried out. An optimized formulation consisting of 1 wt% of blend (40 wt% RECOLAS103) in synthetic sea water was found stable and able to reduce water-oil interfacial tension down to 0.02 mN/m. The dynamic blend adsorption in carbonate rocks was found to be 0.60 mg/grock, a promising value for the application. Core flooding tests were conducted at 25 and 120 °C and additional oil recoveries achieved ranged from 10.2 to 12.7% of the original oil in place, the lowest production obtained at the highest temperature. This work offers an advance in the application of surfactants for EOR in carbonate reservoirs, since it improves previous proposals that show stability or high adsorption problems. Moreover, a chemical injection optimization was also carried out by simulation with the CMG-STARS software. Results point to the possibility of reaching higher oil recoveries than those obtained experimentally if the extraction method is optimizedS
Latest Cretaceous palaeogeographic evolution of northeast Iberia: Insights from the Campanian continental MontalbĂĄn subbasin (Spain)
This work characterizes for the first time the 500â700Â m-thick uppermost Cretaceous continental sedimentary succession of the Allueva Fm recorded in the northeastern margin of the Iberian basin, in the MontalbĂĄn subbasin (Maestrazgo domain, Spain). The middle-upper Campanian age of this unit constrained here by new paleomagnetic and biostratigraphic data involves major revision of previous stratigraphic and palaeogeographic interpretations. The uplift of the northern marginal areas of the MontalbĂĄn subbasin onwards from the middle Campanian supplied the coarse terrigenous-clastic sediments common in the alluvial Allueva Fm. Moreover, a sharp increase of the sedimentation rates (from 4 to 19Â cm/ky) from the lower to the middle-upper part of the Allueva Fm has been related to further increase of the tectonic activity during the middle part of the late Campanian. Also relevant are the new discovered vertebrate sites mostly found in the marginal areas of a large lacustrine-palustrine carbonate system developed during the latest Campanian. Vertebrate sites include a fossil assemblage with abundance of titanosaur sauropod dinosaurs as well as the presence of ornithopod dinosaurs and crocodylomorphs. A review of the dinosaur fossil sites recorded in other Iberian subbasins shows a similar fossil assembage occurrence during the late Campanianâearliest Maastrichtian timespan, previous to the faunal turnover that took place in the Ibero-Armorican landmass around the onset of the late Maastrichtian. The stratigraphic, sedimentological and paleontological characterization of the successions recorded during the initial stages of development of the MontalbĂĄn subbasin have major implication to understand the latest Cretaceous palaeogeographic evolution of northeast Iberia. Comparative review to other latest Cretaceous continental successions deposited in other domains of the Iberian basin indicates a south to north migration of newly developed subsident subbasins: during the Campanian (South Iberian domain), during the middle-late Campanian (northern Maestrazgo domain), and during the Maastrichtian (central Castillian domain)

Intraarterial route increases the risk of cerebral lesions after mesenchymal cell administration in animal model of ischemia
Mesenchymal stem cells (MSCs) are a promising clinical therapy for ischemic stroke. However, critical parameters, such as the most effective administration route, remain unclear. Intravenous (i.v.) and intraarterial (i.a.) delivery routes have yielded varied outcomes across studies, potentially due to the unknown MSCs distribution. We investigated whether MSCs reached the brain following i.a. or i.v. administration after transient cerebral ischemia in rats, and evaluated the therapeutic effects of both routes. MSCs were labeled with dextran-coated superparamagnetic nanoparticles for magnetic resonance imaging (MRI) cell tracking, transmission electron microscopy and immunohistological analysis. MSCs were found in the brain following i.a. but not i.v. administration. However, the i.a. route increased the risk of cerebral lesions and did not improve functional recovery. The i.v. delivery is safe but MCS do not reach the brain tissue, implying that treatment benefits observed for this route are not attributable to brain MCS engrafting after stroke.This study has been partially supported by grants from Axencia Galega de InnovaciĂłn (Xunta de Galicia), the Instituto de Salud Carlos III (PI13/00292; PI14/01879), the Spanish Research Network on Cerebrovascular Diseases RETICS-INVICTUS (RD12/0014), Xunta de Galicia (ConsellerĂa EducaciĂłn GRC2014/027), the European Commission program FEDER and Promoting Active Ageing program: Functional Nanostructures For Alzheimerâs Disease At Ultra-Early Stagesâ (Pana_686009), a Research and Innovation Project, funded within the EU Horizon 2020 Programmeâ.
