Emerging Spin-Orbit Torques in Low Dimensional Dirac Materials

We report a theoretical description of novel spin-orbit torque components emerging in two-dimensional Dirac materials with broken inversion symmetry. In contrast to usual metallic interfaces where field-like and damping-like torque components are competing, we find that an intrinsic damping-like torque which derives from all Fermi-sea electrons can be simultaneously enhanced along with the field-like component. Additionally, hitherto overlooked torque components unique to Dirac materials, emerge from the coupling between spin and pseudospin degrees of freedom. These torques are found to be resilient to disorder and could enhance the magnetic switching performance of nearby magnets

Anthocyanin composition in fig (Ficus carica L.)

[EN] The anthocyanin composition was analysed in fig fruit (Ficus carica L.) from five different varieties (Colar, Cuello de Dama (green), Cuello de Dama (dark purple), Granilla and Bursa Siyahi). Fifteen anthocyanin pigments were detected, most of them containing cyanidin (Cy) as aglycone; some pelargonidin (Pg) derivatives were also found. Rutinose and glucose were present as substituting sugars, as well as acylation with malonic acid. Minor levels of peonidin 3-rutinose (Pn 3-rutinoside) in the pulp were also detected. Other noticeable aspects in the pigment composition of the fig were the detection of anthocyanidin-derived pigments, namely 5-carboxypyranocyanidin-3-rutinoside, a cyanidin 3-rutinose dimer and five condensed pigments containing C–C linked anthocyanins (Cy and Pg) and flavanol (catechin and epicatechin) residues. Total anthocyanin content in the skin ranged between 32 and 97 mgg 1 and between 1.5 and 15 mgg 1 in the pulp. The main anthocyanin in both parts of the fruit was Cy 3-rutinoside (48–81% in skin and 68–79% in pulp) usually followed by Cy 3-glucoside (5–18% in skin and 10–15% in pulp). Malonyl derivatives were more abundant in the skin (1.2–6.5%) than in the pulp (1.0–2.6%)

Analysis of the influenza season 2017-2018, predominance of the Yamagata lineage of influenza B in adults

[spa] Introducción: Se analizan las características epidemiológicas y virológicas de la temporada gripal 2017-2018 en sus aspectos de mortalidad y grupos etários. Pacientes y método: Las muestras respiratorias proceden tanto de la Red Centinela de Vigilancia de la Gripe como de los pacientes atendidos en urgencias y hospitalizados en nuestro centro fueron sometidas a la detección de los virus respiratorios mediante una técnica de amplificación genómica comercial, tipo RT-PCR (Allplex Respiratory Panel; Seegen, Corea del Norte), que identifica de forma simultánea y diferencial 16 virus respiratorios distintos. Entre ellos los virus gripales A (H1N1)pdm09 y A(H3N2) y el virus gripal tipo B, aunque no diferencia entre sus dos linajes. Resultados: A lo largo de la temporada gripal se han analizado 6.465 muestras respiratorias, de las cuales 3.228 (49.9%) fueron consideradas positivas (detección de algún virus respiratorio). De ellas, en 1.232 se detectó un virus gripal, representando el 19% de todas las muestras procesadas y el 38.2% de todas las muestras positivas. De todos los virus gripales detectados, 661 (53.6%) fueron identificados como gripe A y 571 (46.4%) gripe B. La RCVG aportó 127 (10.3%) muestras positivas, 58 (8.7%) gripo A y 69 (12%) gripe B. El resto de muestras positivas, 1.105 (89.7%), procedían del ámbito hospitalario, es decir 603 (91.3%) eran gripe A y 502 (88%) eran gripe B. En cuanto a los subtipos de la gripe A se detectaron 415 (62.7%) casos del subtipo A (H1N1) pdm09, 38 (9.1%) de la RCVG y 377 (90.9%) del ámbito hospitalario. Del subtipo A (H3N2) se detectaron 246 (37.3%) casos, de los cuales 20 (8.1%) pertenecían a la RCVG y 226 (91.9%) al ámbito hospitalario. Al analizar los subtipos sobre el total de muestras de cada procedencia se comprueba como de los 58 casos de gripe A pertenecientes a la RCVG 38 (65.5%) eran A (H1N1)pdm09 y 20 (34.5%) A (H3N2). En el ámbito hospitalario, de los 603 casos de gripe A, 377 (62.5%) eran A (H1N1)pdm09 y 226 (37.5%) eran A (H3N2), no observándose diferencias significativas. Conclusiones: La temporada gripal 2017-2018 debe considerarse como una temporada atípica en la que la cocirculación de los cuatro tipos/subtipos gripales determinó la mayor tasa epidemiológica y el mayor número de casos registrado en las Islas Baleares.[eng] Introduction: The epidemiological and virological characteristics of the 2017-2018 flu season in its aspects of mortality and age groups are analyzed. Patients and method: Respiratory samples from both the Sentinel Influenza Surveillance Network and patients treated in the emergency room and hospitalized in our center were subjected to the detection of respiratory viruses using a commercial genomic amplification technique, type RT- PCR (Allplex Respiratory Panel, Seegen, North Korea), which identifies 16 different respiratory viruses simultaneously and differentially. Among them influenza viruses A (H1N1) pdm09 and A (H3N2) and influenza virus type B, although no difference between their two lineages. Results: During the flu season, 6,465 respiratory samples were analyzed, of which 3,228 (49.9%) were considered positive (detection of a respiratory virus). Of these, in 1232 a flu virus was detected, representing 19% of all processed samples and 38.2% of all positive samples. Of all the influenza viruses detected, 661 (53.6%) were identified as influenza A and 571 (46.4%) influenza B. The RCVG contributed 127 (10.3%) positive samples, 58 (8.7%) group A and 69 (12%) Influenza B. The rest of the positive samples, 1,105 (89.7%), came from the hospital setting, that is, 603 (91.3%) were influenza A and 502 (88%) were influenza B. Regarding the subtypes of influenza A, They detected 415 (62.7%) cases of the subtype A (H1N1) pdm09, 38 (9.1%) of the RCVG and 377 (90.9%) of the hospital setting. Subtype A (H3N2) detected 246 (37.3%) cases, of which 20 (8.1%) belonged to the RCVG and 226 (91.9%) to the hospital setting. When analyzing the subtypes on the total samples of each provenance, it is verified that of the 58 cases of influenza A belonging to the RCVG 38 (65.5%) were A (H1N1) pdm09 and 20 (34.5%) A (H3N2). In the hospital setting, of the 603 cases of influenza A, 377 (62.5%) were A (H1N1) pdm09 and 226 (37.5%) were A (H3N2), no significant differences were observed. Conclusions: The 2017-2018 flu season should be considered as an atypical season in which the co-circulation of the four flu types / subtypes determined the highest epidemiological rate and the highest number of cases registered in the Balearic Islands

Scattering of 8He on 208Pb at Energies Around the Coulomb Barrier

We have measured the angular distributions of elastic scattering and 6,4He fragments produced in the collisions of an exotic beam of 8He on a 208Pb target at laboratory energies of 18 and 22 MeV, just around the Coulomb barrier (19 MeV). The measurements were performed at the SPIRAL/GANIL facility in Caen, France. In this paper, we present preliminary data on elastic cross sections and discuss the results using optical model and coupled reaction channel calculations.Spanish Research Council FPA-2010-22131-C02-01Ministry of Science and Higher Education of Poland No. N202 03363
