Post-tonal music often poses perceptual and cognitive challenges for listeners, potentially related to the use of relatively uncommon and unfamiliar musical material and compositional processes. As a basic compositional device, repetition affects memory for music and is structured by composers in very different ways across tonal and post-tonal musical repertoires. Of particular concern is whether post-tonal music exhibits mnemonic affordances that allow listeners to experience a sense of global coherence, and whether repetition correlates strongly with aesthetic judgment. Although previous research suggests that repetition impacts aesthetic preference, empirical research has not mapped out …
Reversible guest-induced gate-opening with multiplex spin crossover responses in two-dimensional Hofmann clathrates.
2021
Spin crossover (SCO) compounds are very attractive types of switchable materials due to their potential applications in memory devices, actuators or chemical sensors. Rational chemical tailoring of these switchable compounds is key for achieving new functionalities in synergy with the spin state change. However, the lack of precise structural information required to understand the chemical principles that control the SCO response with external stimuli may eventually hinder further development of spin switching-based applications. In this work, the functionalization with an amine group in the two-dimensional (2D) SCO compound {Fe(5-NH2Pym)2[MII(CN)4]} (1M, 5-NH2Pym = 5-aminopyrimidine, MII =…
2D ECG Image Based Biometric Identification Using Stacked Autoencoders
2021
The handcrafted features extraction methods have achieved remarkable results in ECG based biometric identification. However, they are sensitive to many factors: (1) intra and inter-individual variability, (2) heart rate variability, (3) powerline interference, baseline wander and muscle artifacts. To deal with these issues, deep learning approaches have been proposed to extract automatically the important features almost from original data without any preprocessing step (i.e., The original ECG signal mostly contains noise). Unlike conventional ECG based biometric approaches, which based either on fiducial and non-fiducial methods, the proposed approach can be implemented on end to end syste…
La distribución de cortometrajes en la era digital. Entry fees y plataformas de distribución.

Con el cierre por parte de Amazon de la plataforma americana de distribución de obras audiovisuales Withoutabox parece haberse abierto una nueva perspectiva acerca de quién ocupará el lugar hegemónico dentro de la batalla por la distribución del cortometraje en Internet. Mucho ha avanzado el sistema industrial de la distribución desde que con el auge del mundo digital los envíos online fueran ganando poco a poco espacio al tradicional envío postal. Así, varios actores de distinta procedencia tales como Filmfreeway, Festhome, Clickforfestivals, Movibeta, Filmfestivallife o Shotfilmdepot pugnan por ganar espacio en un competitivo mercado que ha eliminado intermediarios estrechando la relación…
Search for trilepton resonances from chargino and neutralino pair production in s=13 TeV pp collisions with the ATLAS detector
2021
A search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an $R$-parity-violating coupling into a lepton and a $W$, $Z$, or Higgs boson. The trilepton invariant-mass spectrum is constructed from events with three or more leptons, targeting chargino decays that include an electron or muon and a leptonically decaying $Z$ boson. The analyzed dataset corresponds to an integrated luminosity of 139 fb$^{-1}$ of proton-proton collision data produced by the Large Hadron Collider at a center-of-mass energy of $\sqrt{s}$ = 13 TeV and collected by the ATLAS experiment between 2015 and 2018. The data are f…

Design of the EBE-ST Questionnaire among Nursing Students: Multicenter Study from Eight Universities in Spain
2021
Background: Twenty years after the degree in nursing was introduced in Spain, the subject of evidence-based nursing is still unstructured and unestablished in most faculties. Moreover, there are hardly any rigorous studies at a national level that evaluate the current state of this competence in our faculties. Understanding the starting point is essential for the curricular design to ensure that evidence-based practice is implemented among future professionals. Aim: To design and validate an evidence-based nursing competency questionnaire for fourth-year nursing students. Methods: A specific questionnaire was developed and validated (EBE-ST). A cross-sectional survey design with psychometri…
Does the memory of a first water deficit enable a more efficient response to a subsequent water deficit?
2021
National audience; In the current context of climate change, periods of water deficit occur more frequentlyalong the crop cycle, leading to high yield losses. To limit the negative impact of recurrentwater deficits, plants can adapt, via the mobilization of “stress memory”, allowing them torespond to a subsequent stress in a faster and/or more intensive manner. After a first stressevent, plants can keep an imprint of this stress via the induction of epigenetic (e.g. memorygene regulation), physiological (e.g. stomatal closure) and molecular (e.g. compoundaccumulation) changes. When maintained between two stress periods, these changes mayprepare plants for a subsequent water deficit.This wor…
Influence of a Cu–zirconia interface structure on CO2 adsorption and activation
2021
CO2 adsorption and activation on a catalyst are key elementary steps for CO2 conversion to various valuable products. In the present computational study, we screened different Cu–ZrO2 interface structures and analyzed the influence of the interface structure on CO2 binding strength using density functional theory calculations. Our results demonstrate that a Cu nanorod favors one position on both tetragonal and monoclinic ZrO2 surfaces, where the bottom Cu atoms are placed close to the lattice oxygens. In agreement with previous calculations, we find that CO2 prefers a bent bidentate configuration at the Cu–ZrO2 interface and the molecule is clearly activated being negatively charged. Strain…

2021
Artikkeli keskittyy digitaalisen ympäristöllisyyden käsitteeseen kirjallisuudentutkimuksen näkökulmasta. Ympäristöllisyydellä viittaamme digitaalisen teknologian luomiin olosuhteisiin, jotka ympäröivät ja muovaavat erilaisia kirjoittamisen ja lukemisen tilanteita: se paitsi tekee analogisen ja digitaalisen vastakkainasettelusta riittämättömän lähtökohdan näiden tilanteiden hahmottamiselle, myös muokkaa sekä kirjoittavaa ja lukevaa subjektia että kirjallisen toimijuuden muitakin muotoja. Tästä lähtökohdasta tutkimme ja jäsennämme ympärristöllisyyden merkitystä kirjallisuudentutkimukselle. Tarkastelemme teknologian, kirjallisuuden ja niiden ihmiskäyttäjän toimijuuden yhteyttä niissä digitaali…
Colossal barocaloric effects in the complex hydride Li$_{2}$B$_{12}$H$_{12}$
2021
Traditional refrigeration technologies based on compression cycles of greenhouse gases pose serious threats to the environment and cannot be downscaled to electronic device dimensions. Solid-state cooling exploits the thermal response of caloric materials to external fields and represents a promising alternative to current refrigeration methods. However, most of the caloric materials known to date present relatively small adiabatic temperature changes ($|\Delta T| \sim 1$ K) and/or limiting irreversibility issues resulting from significant phase-transition hysteresis. Here, we predict the existence of colossal barocaloric effects (isothermal entropy changes of $|\Delta S| \sim 100$ JK$^{-1}…

Que voten los niños. Reflexiones en torno a una propuesta de David Runciman
2021
De unos años a esta parte, el catedrático de Teoría política de la Universidad de Cambridge, David Runciman, viene defendiendo una extensión del derecho al voto que incluya a los niños y niñas en Educación Primaria, esto es, desde los seis años hacia adelante. No es el único: se trata de un debate vivo en algunos círculos académicos, que por el momento se concreta en la petición de rebajar la edad de sufragio a los dieciséis, como sucede en Austria (Marshall, 2017). Este texto trata de identificar las consecuencias sociales, políticas y educativas que se derivarían de la extensión del derecho a voto a los seis años, y concluye que tal medida sería deseable.

The influence of decision-making in tree ring-based climate reconstructions.
2021
Tree-ring chronologies underpin the majority of annually-resolved reconstructions of Common Era climate. However, they are derived using different datasets and techniques, the ramifications of which have hitherto been little explored. Here, we report the results of a double-blind experiment that yielded 15 Northern Hemisphere summer temperature reconstructions from a common network of regional tree-ring width datasets. Taken together as an ensemble, the Common Era reconstruction mean correlates with instrumental temperatures from 1794–2016 CE at 0.79 (p < 0.001), reveals summer cooling in the years following large volcanic eruptions, and exhibits strong warming since the 1980s. Differing in…

Compressibility and phase stability of iron-rich ankerite
2021
ABSTRACT: The structure of the naturally occurring, iron-rich mineral Ca₁․₀₈(₆)Mg₀.₂₄(₂)Fe₀.₆₄(₄)Mn₀.₆₄(₄)(CO₃)₂ ankerite was studied in a joint experimental and computational study. Synchrotron X-ray powder diffraction measurements up to 20 GPa were complemented by density functional theory calculations. The rhombohedral ankerite structure is stable under compression up to 12 GPa. A third-order Birch-Murnaghan equation of state yields V₀ = 328.2(3) ų, bulk modulus B₀ = 89(4) GPa, and its first-pressure derivative B'₀ = 5.3(8)-values which are in good agreement with those obtained in our calculations for an ideal CaFe(CO₃)₂ ankerite composition. At 12 GPa, the iron-rich ankerite structure …
Psychiatric Problems in Adolescence Mediate the Association Between Childhood Learning Disabilities and Later Well-Being
2021
This follow-up study investigated the associations of childhood learning disabilities (LDs) with adult-age anxiety, depression, and unemployment. Psychosocial problems in childhood and psychiatric diagnoses and lack of education in adolescence were studied as potential mediators, and gender and mother’s education were studied as potential moderators of these associations. Data on childhood clinical neuropsychological assessments and lifelong register data on individuals with childhood LD ( n = 430; 301 [70%] males; 20–39 years of age) and matched controls ( n = 2,149) were applied. Mediation analyses were performed using structural equation modeling. Childhood LDs exerted a significant, bu…
Role of expectancy in physiological responses to sound recognition of musical dissonance and timbral change
2021
Recently, it has been suggested that tonal violations produce greater skin conductance response (SCR) than timbral violations in music listening. However, it is unknown how people focus their attention during musical excerpts. The aim of this study is to replicate previous research considering two psychophysiological mechanisms: prediction error and brain stem reflex. Twenty-seven nonmusicians were instructed to listen six melodies and detect three altered conditions in one note: a dissonance (note out-of-key), a timbral change, and dissonance which changes in timbre and tone ( timdis). Amplitudes of SCR, heart rate (HR), and respiration rate (RSPR) were analyzed. In addition, the frequenc…
Could isotretinoin be a protective agent against COVID-19?: A dermatologist perspective.

Puppeteering as a metaphor for unpacking power in participatory action research on climate change and health
2021
The health impacts of climate change are distributed inequitably, with marginalized communities typically facing the direst consequences. However, the concerns of the marginalized remain comparatively invisible in research, policy and practice. Participatory action research (PAR) has the potential to centre these concerns, but due to unequal power relations among research participants, the approaches often fall short of their emancipatory ideals. To unpack how power influences the dynamics of representation in PAR, this paper presents an analytical framework using the metaphor of ‘puppeteering’. Puppeteering is a metaphor for how a researcher-activist resonates and catalyses both the voices…
