Spiral arm crossings inferred from ridges in Gaia stellar velocity distributions

The solar neighborhood contains disc stars that have recently crossed spiral arms in the Galaxy. We propose that boundaries in local velocity distributions separate stars that have recently crossed or been perturbed by a particular arm from those that haven't. Ridges in the stellar velocity distributions constructed from the second Gaia data release trace orbits that could have touched nearby spiral arms at apocentre or pericentre. The multiple ridges and arcs seen in local velocity distributions are consistent with the presence of multiple spiral features and different pattern speeds and imply that the outer Galaxy is flocculent rather than grand design.Comment: For a movie https://youtu.be/5nbtNYDobc

Propuesta de un plan de sucesión para preservar las competencias laborales propias en “Petróleos del Perú- Operaciones Oleoducto”- Piura, año 2018

La presente investigación denominada propuesta de un plan de sucesión para preservar las competencias laborales propias en “Petróleos del PerúOperaciones Oleoducto”- Piura, año 2018, tiene como objetivo general determinar qué plan de sucesión ayudará a preservar las competencias laborales propias de “Petróleos del Perú - Oleoducto”- Piura, año 2018. Se trata de una investigación descriptiva, no probabilística y transversal, su línea de investigación es Gestión de Organizaciones, realizado a una población de 401 trabajadores estables de Petroperú Oleoducto. Se aplicaron tres instrumentos de recopilación de información: Para el cuestionario, mediante el Software Epidat 4.2 (Análisis epidemiológico de datos) se obtuvo una muestra de 197 trabajadores a quienes, en forma estratificada se aplicó un cuestionario de 15 preguntas; para la entrevista se realizó un muestreo no probabilístico discrecional, aplicando una guía de entrevista de 12 preguntas a 5 puestos directivos; también una ficha de análisis documental que analiza información histórica de procesos realizados. Finalmente, se concluye que la empresa no tiene plan de sucesión definido, con lineamientos establecidos para suceder puestos claves anticipadamente y espera el retiro del titular para recién cubrir su vacante, quien se lleva toda la experiencia de años de servicio, sin oportunidad de transmitirla a un sucesor idóneo; sin embargo, dentro de la organización hay trabajadores que cuentan con las competencias requeridas para aplicar el plan de sucesión de puestos claves

Mentoría y formación del profesorado novel para la comunicación emocional en los centros de difícil desempeño

El profesorado que ingresa por primera vez en un centro educativo se encuentra con una realidad que probablemente imaginara de otra manera, las dificultades que pueden surgir se ven incrementadas por las características propias de los centros educativos catalogados como de difícil desempeño. Estos centros están enmarcados en un espacio geográfico determinado, barrios circundantes, segregados. Esto supone que una buena parte de la población sufre una importante desconexión. El perfil del alumnado de estos centros, suelen ser: afectivos, emotivos, impulsivos (Agresivos), poco reflexivos, dinámicos, activo y diluyen su responsabilidad personal en el amparo del grupo. En este sentido el profesorado novel encuentra mayor dificultad en el inicio de su trayectoria profesional. Por eso los procesos de Mentoría ofrecen estrategias específicas de la mano de un experto, que se traducirán en mejoras de la práctica docente. Ser capaz de reconocer las expresiones emocionales en el alumnado y de expresarlas no es siempre fácil, por eso la propuesta es ir acompañado de profesorado veterano que ejerza como mentor para la mejora de la gestión del aula

A self-driven approach for multi-class discrimination in Alzheimer’s disease based on wearable EEG

Early detection is critical to control Alzheimer’s disease (AD) progression and postpone cognitive decline. Traditional medical procedures such as magnetic resonance imaging are costly, involve long waiting lists, and require complex analysis. Alternatively, for the past years, researchers have successfully evaluated AD detection approaches based on machine learning and electroencephalography (EEG). Nonetheless, these approaches frequently rely upon manual processing or involve non-portable EEG hardware. These aspects are suboptimal regarding automated diagnosis, since they require additional personnel and hinder porta- bility. In this work, we report the preliminary evaluation of a self-driven AD multi-class discrimination approach based on a commercial EEG acquisition system using sixteen channels. For this purpose, we recorded the EEG of three groups of participants: mild AD, mild cognitive impairment (MCI) non-AD, and controls, and we implemented a self-driven analysis pipeline to discriminate the three groups. First, we applied automated artifact rejection algorithms to the EEG recordings. Then, we extracted power, entropy, and complexity features from the preprocessed epochs. Finally, we evaluated a multi-class classification problem using a multi-layer perceptron through leave-one-subject-out cross-validation. The preliminary results that we obtained are comparable to the best in literature (0.88 F1-score), what suggests that AD can potentially be detected through a self-driven approach based on commercial EEG and machine learn- ing. We believe this work and further research could contribute to opening the door for the detection of AD in a single consultation session, therefore reducing the costs associated to AD screening and poten- tially advancing medical treatment.Spanish Government PGC2018-098813-B-C31European Commission Operative Program FEDER 2014-2020 BTIC-352-UGR20Economy, Universities and Science Office of the Andalusian Regional GovernmentUniversidad de Granada/CBU

An Automated Approach for the Detection of Alzheimer’s Disease From Resting State Electroencephalography

Early detection is crucial to control the progression of Alzheimer’s disease and to postpone intellectual decline. Most current detection techniques are costly, inaccessible, or invasive. Furthermore, they require laborious analysis, what delays the start of medical treatment. To overcome this, researchers have recently investigated AD detection based on electroencephalography, a non-invasive neurophysiology technique, and machine learning algorithms. However, these approaches typically rely on manual procedures such as visual inspection, that requires additional personnel for the analysis, or on cumbersome EEG acquisition systems. In this paper, we performed a preliminary evaluation of a fully-automated approach for AD detection based on a commercial EEG acquisition system and an automated classification pipeline. For this purpose, we recorded the resting state brain activity of 26 participants from three groups: mild AD, mild cognitive impairment (MCI-non-AD), and healthy controls. First, we applied automated data-driven algorithms to reject EEG artifacts. Then, we obtained spectral, complexity, and entropy features from the preprocessed EEG segments. Finally, we assessed two binary classification problems: mild AD vs. controls, and MCI-non-AD vs. controls, through leave-one-subject-out cross-validation. The preliminary results that we obtained are comparable to the best reported in literature, what suggests that AD detection could be automatically detected through automated processing and commercial EEG systems. This is promising, since it may potentially contribute to reducing costs related to AD screening, and to shortening detection times, what may help to advance medical treatment.PID2021-128529OA-I00 Spanish Ministry of Science, Innovation and UniversitiesEuropean Regional Development FundsBTIC- 352-UGR20Operative Program FEDER 2014–2020Economy, Universities and Science Office of the Andalusian Regional Governmen

GDNF gene is associated with tourette syndrome in a family study

Huertas-Fernández, Ismael et al.[Background] Tourette syndrome is a disorder characterized by persistent motor and vocal tics, and frequently accompanied by the comorbidities attention deficit hyperactivity disorder and obsessive-compulsive disorder. Impaired synaptic neurotransmission has been implicated in its pathogenesis. Our aim was to investigate the association of 28 candidate genes, including genes related to synaptic neurotransmission and neurotrophic factors, with Tourette syndrome.[Methods] We genotyped 506 polymorphisms in a discovery cohort from the United States composed of 112 families and 47 unrelated singletons with Tourette syndrome (201 cases and 253 controls). Genes containing significant polymorphisms were imputed to fine-map the signal(s) to potential causal variants. Allelic analyses in Tourette syndrome cases were performed to check the role in attention deficit hyperactivity disorder and obsessive-compulsive disorder comorbidities. Target polymorphisms were further studied in a replication cohort from southern Spain composed of 37 families and three unrelated singletons (44 cases and 73 controls).[Results] The polymorphism rs3096140 in glial cell line–derived neurotrophic factor gene (GDNF) was significant in the discovery cohort after correction (P = 1.5 × 10−4). No linkage disequilibrium was found between rs3096140 and other functional variants in the gene. We selected rs3096140 as target polymorphism, and the association was confirmed in the replication cohort (P = 0.01). No association with any comorbidity was found.[Conclusions] As a conclusion, a common genetic variant in GDNF is associated with Tourette syndrome. A defect in the production of GDNF could compromise the survival of parvalbumin interneurons, thus altering the excitatory/inhibitory balance in the corticostriatal circuitry. Validation of this variant in other family cohorts is necessary. © 2015 International Parkinson and Movement Disorder SocietyThis study was supported by New Jersey Center for Tourette Syndrome and Associated Disorders (NJCTS), the National Institute of Mental Health (R01MH092293), the Instituto de Salud Carlos III (PI10/01674, PI13/01461, PI14/01823), the Consejería de Economía, Innovación, Ciencia y Empresa de la Junta de Andalucía (CVI-02526, CTS-7685), the Consejería de Salud y Bienestar Social de la Junta de Andalucía (PI-0741/2010, PI-0437-2012, PI-0471-2013), the Sociedad Andaluza de Neurología, the Fundación Alicia Koplowitz, the Fundación Mutua Madrileña and the Jaques and Gloria Gossweiler Foundation.

Kinematics with Gaia DR2 : the force of a dwarf

We use Gaia DR2 astrometric and line-of-sight velocity information combined with two sets of distances obtained with a Bayesian inference method to study the 3D velocity distribution in the Milky Way disc. We search for variations in all Galactocentric cylindrical velocity components (Vϕ, VR, and Vz) with Galactic radius, azimuth, and distance from the disc mid-plane. We confirm recent work showing that bulk vertical motions in the R–z plane are consistent with a combination of breathing and bending modes. In the x–y plane, we show that, although the amplitudes change, the structure produced by these modes is mostly invariant as a function of distance from the plane. Comparing to two different Galactic disc models, we demonstrate that the observed patterns can drastically change in short time intervals, showing the complexity of understanding the origin of vertical perturbations. A strong radial VR gradient was identified in the inner disc, transitioning smoothly from 16 km s−1 kpc−1 at an azimuth of 30° < ϕ < 45° ahead of the Sun-Galactic centre line to −16 km s−1 kpc−1 at an azimuth of −45° < ϕ < −30° lagging the solar azimuth. We use a simulation with no significant recent mergers to show that exactly the opposite trend is expected from a barred potential, but overestimated distances can flip this trend to match the data. Alternatively, using an N-body simulation of the Sagittarius dwarf–Milky Way interaction, we demonstrate that a major recent perturbation is necessary to reproduce the observations. Such an impact may have strongly perturbed the existing bar or even triggered its formation in the last 1–2 Gyr

Conversión de CO₂ a carbonatos cíclicos en presencia de hidróxidos dobles laminares Mg/Cr

En este trabajo, se describe el uso de hidróxidos dobles laminares (HDLs) Mg/Cr y sus óxidos mixtos correspondientes, como catalizadores en la reacción de cicloadición de CO₂ a óxido de estíreno. El proceso catalítico desarrollado es altamente eficiente con rendimientos del 90% a una presión de 1.5 bar. En dichas condiciones de presión es posible promover la formación del carbonato cíclico sin modificar la estructura del catalizador, permitiendo su reutilización por tres ciclos más de reacción. La metodología planteada permite el uso de derivados con diversos grupos sustituyentes en el anillo del epóxido, obteniendo los productos correspondientes en rendimientos que van desde 80% hasta el 90%
