Enhancement of synchronized vortex lattice motion in hybrid magnetic/amorphous superconducting nanostructures
Superconducting a-Mo_(3)Si and Nb films have been grown on arrays of Ni nanodots. We have studied the vortex lattice dynamics close to critical temperatures. Different vortex lattice configurations are obtained with the same array unit cell. These different vortex lattices occur at matching conditions between the vortex lattice and the array unit cell. The interplay between the random intrinsic pinning of the superconducting films and the periodic pinning of the array govern the vortex lattice configurations. Different vortex lattice configurations and enhancement of synchronized vortex lattice motion are obtained by increasing the periodic pinning strength and decreasing the random pinning strength
Word-initial rhotic clusters in Spanish-speaking preschoolers in Chile and Granada, Spain
Versión aceptada
Versión online publicada en 2017
Versión Print publicada en 2018The current paper describes Spanish acquisition of rhotic onset clusters.
Data are also provided on related singleton taps/trills and /l/ as a single ton and in clusters. Participants included 9 typically developing (TD)
toddlers and 30 TD preschoolers in Chile, and 30 TD preschoolers and
29 with protracted phonological development (PPD) in Granada, Spain.
Results showed age and developmental group effects. Preservation of
cluster timing units preceded segmental accuracy, especially in stressed
syllables. Tap clusters versus singleton trills were variable in order of
mastery, some children mastering clusters first, and others, the trill.
Rhotics were acquired later than /l/. In early development, mismatches
(errors) involved primarily deletion of taps; where substitutions occurred,
[j] frequently replaced tap. In later development, [l] more frequently
replaced tap; where taps did occur, vowel epenthesis sometimes
occurred. The data serve as a criterion reference database for onset cluster
acquisition in Chilean and Granada Spanish.Thank you also for funding by the:

Comprehending socio-relational factors of mental wellbeing in the oldest old within Nordic and Mediterranean countries
Socio-relational aspects are essential for mental wellbeing (MWB), especially in the oldest
old age. Our study aims to explore the socio-relational aspects related to MWB in accord ance with the experiences of the oldest old of four European countries; and to examine
how these differ between Mediterranean and Nordic people. A total of 117 participants
aged 80+ years old were recruited, and 23 focus groups were performed. Qualitative con tent analysis identified five main themes. Family seemed to be the most important driver
of the MWB of the oldest old, followed by relationships with close friends. Participants felt
better when they had a sense of being needed, cared for, and connected. Loneliness and
isolation negatively affected MWB, although solitude was appreciated. Differences
appeared between Mediterranean and Nordic regions. Initiatives to promote positive
interactions with family and friends, as well as social activities within the community,
may contribute to strengthening MWB in the oldest ol
Repetición de pseudopalabras en niños con síndrome de Down
el síndrome de Down (SD) es un trastorno genético que se expresa en
distintas alteraciones físicas, sensoriales y cognitivas. Se describe que los
niños con SD presentan alteración en la repetición de las pseudopalabras.
Sin embargo, la mayoría de las investigaciones son en lengua inglesa. el
objetivo de la presente investigación fue evaluar el rendimiento de niños
con síndrome de Down de habla española, en una prueba de pseudopa labras cuando los factores de audición, vocabulario e ininteligibilidad
fueron controlados. La muestra estuvo compuesta por 26 sujetos distri buidos en dos grupos: 13 niños con síndrome de Down y 13 niños con
desarrollo normal del lenguaje. Los resultados corroboran los hallazgos
en otras lenguas, es decir, los niños con SD de este estudio mostraron
un rendimiento deficiente en la repetición de palabras y pseudopalabras,
existieron diferencias significativas en pseudopalabras simples y no se
observó un efecto de longitud de palabras. en la conclusión se trata de dar
una explicación a los resultados encontrados y se plantea la eficacia del
uso de una prueba de pseudopalabras para medir la memoria de trabajo
fonológica en menores con S

Contaminantes orgánicos persistentes en leche materna de centros urbanos de la provincia de Buenos Aires
Due to their chemical persistence and high lipophilicity, persistent organic pollutants (POPs) have a tendency to accumulate and biomagnify in the food chain. Because of its easy noninvasive collection and high-fat content, human milk is a good indicator POPs in human populations. The aim of our study was to evaluate human exposure to POPs (PCBs, DDTs and its metabolites, α, β y γ HCHs, CHLDs: heptachlor, heptachlor epoxide, trans- and cis-chlordanes and nonachlors) in 59 human milk samples collected during 2010-2011 in Punta Lara, Ensenada, Florencio Varela and Buenos Aires.Los contaminantes orgánicos persistentes (COPs) se acumulan en matrices ricas en materia grasa como la leche materna, que es un buen indicador de sus niveles en poblaciones humanas debido a su fácil y no invasiva extracción. Con el objeto de evaluar la exposición a COPs en la provincia de Buenos Aires y compararla con otras áreas, se analizaron bifenilos policlorados (PCBs), diclorodifeniltricloroetano (DDT) y sus metabolitos (DDT, TDE), hexaclorociclohexanos (α, β y γ-HCH) y clordanos (CHLDs: heptaclor y su epóxido, trans y cis clordanos y nonaclors) en muestras de leche materna colectadas durante 2010 y 2011 en Punta Lara, Ensenada, Florencio Varela y Capital Federal
Magnetic pinning of flux lattice in superconducting- nanomagnet hybrids
Strong superconducting pinning effects are observed from magnetic landscapes produced by arrays of circular rings with varying magnetic remanent states. The collective and the background pinning of superconducting Nb films is strongly enhanced by the stray magnetic field produced by an array of circular Ni rings magnetized to form “onion” (bidomain) states. On the other hand, when the same rings are magnetized into vortex (flux-closed) states, or are randomly magnetized, the superconducting pinning is much smaller. The greatest pinning is produced when the superconducting vortex lattice motion is along a direction in which there is a strong magnetic field variation
Low levels of CIITA and high levels of SOCS1 predict COVID-19 disease severity in children and adults
It is unclear why COVID-19 ranges from asymptomatic to severe. When SARS-CoV-2 is detected, interferon (IFN) response is activated. When it is insufficient or delayed, it might lead to overproduction of cytokines and severe COVID-19. The aim was to compare cytokine and IFN patterns in children and adults with differing severity with SARS-CoV-2.It was a prospective, observational study, including 84 patients. Patients with moderate/severe disease had higher cytokines' values than patients with mild disease (p< 0.001).Two IFN genes were selected to build a decision tree for severity classification: SOCS1 (representative of the rest of the IFN genes) and CIITA (inverse correlation). Low values of CIITA and high values of SOCS1 indicated severe disease. This method correctly classified 33/38(86.8%) of children and 27/34 (79.4%) of adults.
To conclude, patients with severe disease had an elevated cytokine pattern, which correlated with the IFN response, with low CIITA and high SOCS1 values.This study was supported by the projects PI18/00223, FI19/00208 and PI21/00211 to LA, integrated in the Plan Nacional de I + D + I and co-financed by the ISCIII– Subdirección General de Evaluación y Fomento de la Investigación Sanitaria – and the Fondo Europeo de Desarrollo Regional (FEDER), by Pla Estratègic de Recerca i Innovació en Salut (PERIS), Departament de Salut, Generalitat de Catalunya (SLT006/17/00199 to LA), and by CERCA Program/Generalitat de Catalunya.
