    The method of descending limits assessed motion contrast thresholds of 11 young participants (17–28), and 21 older drivers (63–86) for 0.4 cycle/degree drifting Gabor stimuli at 15 degrees eccentricity. Peripheral motion contrast thresholds (PMCT) of younger participants (M = –45.5 dB, SD = 1.66 dB) and older participants (M = –43.3 dB, SD = 3.79 dB) differed (t(29) = 2.295, p < .05 (all p-values one-tailed)). Older drivers performed UFOV® tests and a high-fidelity driving simulation. Between independent variables, significant correlations were PMCT with UFOV2 (r = .74, p < .001), PMCT with UFOV3 (r = .50, p < .01), PMCT with age (r =.73, p < .001), UFOV2 with age (r = .48, p < .05), and UFOV3 with age (r = .44, p < .05). Between vision and simulator measures, PMCT and UFOV2 significantly predicted rater’s simulator score (r = .66, p < .001; r = .58, p < .01 respectively), and simulator crashes ( r = .63, p < .001; r = .72, p < .001 respectively). Thus, PMCT and UFOV2 strongly predicted simulator performance. Partial correlations showed that: substantial association between PMCT and UFOV2 was not age–related; PMCT and UFOV2 tapped a common visual function; and PMCT assessed a component not captured by UFOV2. The descending limits procedure is as reliable and faster than forcedchoice. A practicable PMCT test that informs at-risk drivers about visual deficits may help them compensate effectively by learning voluntary scanning techniques and by otherwise modifying their driving techniques

    Motion contrast thresholds for 0.4 cycle/degree drifting Gabor stimuli were assessed at 15-degrees eccentricity for 16 younger drivers (ages 24 to 42), and 15 older drivers (ages 65 to 84), using a temporal two-alternative forced choice staircase procedure. Two self-report questionnaires assessed detection failure accident risk—the Driver Perception Questionnaire (DPQ5), and an abridged Aging Driver Questionnaire (ADQ15). The UFOV® test battery was also administered. Mean peripheral motion contrast thresholds (PMCT) of younger and older participants were –39.3 dB and –33.8 dB, respectively. For younger drivers, the correlation between PMCT and DPQ5 scores was .62 (p\u3c.01), and between DPQ5 and ADQ16 (new and validated self-report measures, respectively) was .59 (p\u3c.01). For older drivers, correlation between PMCT and DPQ5 scores was .49 (p\u3c.01), between DPQ5 and ADQ16 was .73 (p\u3c.01), and between PMCT and age was .49 (p\u3c.05). For drivers overall, correlation was .48 (p\u3c.01) between PMCT and DPQ5 scores, .63 (p\u3c.0001) between DPQ5 and ADQ16, and .69 (p\u3c.0001) between PMCT and age. For drivers overall, correlation was .30 (p\u3c.05) between UFOV1 and age, .67 (p\u3c.0001) between UFOV2 and age, .56 (p\u3c.001) between UFOV2 and PMCT, .80 (p\u3c.0001) between UFOV3 and age, and .58 (p\u3c.001) between UFOV3 and PMCT. Holding age constant, partial correlation of PMCT with DPQ5 was .55 (p\u3c.001), and of PMCT with ADQ15 was .39 (p\u3c.05). PMCT significantly predicted self-reported driving performance in a laboratory setting, and worsened significantly with age. PMCT assessment should be made practicable. Informing high-risk drivers may encourage appropriate risk reduction countermeasures

    A través del perfil “wearescienceuem” en la red social Instagram difundimos conocimiento científico. Utilizamos “píldoras educativas” tales como textos breves, escritos en inglés, asociadas a esquemas o imágenes que recogen información actualizada y conceptos básicos de distintos ámbitos de las Ciencias Biomédicas. Así presentamos de un modo mucho más atractivo conceptos del mundo científico, que en un primer momento podrían resultar áridos y pocos estimulantes, despertando la curiosidad de nuestros seguidores y, convirtiéndose en algo mucho más contemporáneo y fácil de comprender. La información está disponible en todo momento y nuestros “followers” visitan el perfil preferentemente durante sus horas de ocio (durante el periodo nocturno). Wearescienceuem es un proyecto dinámico donde se establece una interacción activa y bidireccional entre estudiantes y profesores. Los propios alumnos nos dirigen y ayudan a vertebrar el ritmo y los temas que discutimos en la red social, siguiendo un paralelismo con el contenido de las asignaturas que se imparten a lo largo del curso.SIN FINANCIACIÓNNo data 2018UE

    es la red social menos explorada como recurso didáctico, a pesar de ser una de las más utilizadas por los jóvenes entre 18 y 30 años. Para explorar su uso con esta finalidad hemos creado una cuenta en la hemos desarrollado de manera continuada durante este curso académico un repositorio de contenidos que facilitan la puesta en práctica de un nuevo concepto de flipped classroom. Estos contenidos han sido elaborados por los propios profesores y alumnos, supervisados para que la cuenta se use como referente en las disciplinas en las que los profesores involucrados impartimos clase. En este trabajo, proponemos el uso de las métricas de impacto de la cuenta como recurso innovador para la evaluación de la interacción de los profesores con los alumnos. Gracias a esta acción, hemos facilitado un nuevo canal para que los alumnos sean participantes activos de su proceso de aprendizaje, a la vez que ha repercutido en los propios profesores como elemento de formación en el uso de nuevas tecnologías.SIN FINANCIACIÓNNo data 2019UE

    Influência da fase embrionária dos ovos da traça-das-crucíferas sobre fêmeas de Trichogramma pretiosum com diferentes idades Influence of diamondback moth embrionary egg stage on Trichogramma pretiosum females of different ages

    Plutella xylostella é considerada a praga mais importante das crucíferas. O método de controle mais utilizado para essa praga é o químico. Contudo, esta espécie de inseto vem desenvolvendo resistência aos inseticidas aplicados. O controle biológico com espécies do gênero Trichogramma é considerado uma alternativa no controle dessa praga. Porém, poucos são os trabalhos que mencionam aspectos biológicos desse parasitóide sobre esta praga. Neste trabalho avaliou-se a influência da fase embrionária dos ovos do hospedeiro P. xylostella sobre fêmeas de T. pretiosum com diferentes idades. Fêmeas do parasitóide foram divididas em cinco lotes, compostos por espécimes recém-emergidos com 24; 48; 72 e 96 horas de idade. Cada lote continha dez fêmeas de T. pretiosum. Para cada fêmea de cada lote, foi oferecida uma cartela contendo 30 ovos de P. xylostella com um, dois e três dias de idade. As maiores taxas de parasitismo foram observadas em fêmeas com idade superior a 48 horas, independente do desenvolvimento embrionário do hospedeiro. Em ovos com três dias de desenvolvimento embrionário verificou-se que, para fêmeas recém-emergidas e com 48 horas de idade, a taxa de viabilidade foi superior apenas em relação àquelas com 96 horas de idade. Ao se avaliar os descendentes de T. pretiosum provenientes de ovos com um dia de desenvolvimento embrionário, verificou-se que os maiores valores de longevidade foram obtidos quando as fêmeas desse parasitóide eram recém-emergidas.<br>Plutella xylostella is one of the most important pests of Cruciferae. Chemicals have been used to control this insect, but the rapid development of resistance is a serious constraint to this method. Biological control with Trichogramma species has been reported as an alternative to control diamondback moth. However few works report biological parameters of this parasitoid interacting with this pest. This work was carried out to evaluate the influence of egg embryonary stage of P. xylostella on T. pretiosum females at different ages. Females of this parasitoid were organized in five groups. These groups were composed of females just emerged, 24 h; 48 h; 72 h, and 96 hours-old. Each group was formed of ten females. Each female received a card with thirty P. xylostella eggs, one, two and three day-old. Higher parasitism rates were observed with females older than 48 hours, with no influence of host embryonic development. In three day-old eggs it was verified that just emerged females and 48 hour-old, the viability index was superior just to those 96 hour-old. The progeny with one day of embryonary development, presented higher longevity values with just emerged females

    Multiomic analysis of malignant pleural mesothelioma identifies molecular axes and specialized tumor profiles driving intertumor heterogeneity

    International audienceAbstract Malignant pleural mesothelioma (MPM) is an aggressive cancer with rising incidence and challenging clinical management. Through a large series of whole-genome sequencing data, integrated with transcriptomic and epigenomic data using multiomics factor analysis, we demonstrate that the current World Health Organization classification only accounts for up to 10% of interpatient molecular differences. Instead, the MESOMICS project paves the way for a morphomolecular classification of MPM based on four dimensions: ploidy, tumor cell morphology, adaptive immune response and CpG island methylator profile. We show that these four dimensions are complementary, capture major interpatient molecular differences and are delimited by extreme phenotypes that—in the case of the interdependent tumor cell morphology and adapted immune response—reflect tumor specialization. These findings unearth the interplay between MPM functional biology and its genomic history, and provide insights into the variations observed in the clinical behavior of patients with MPM

    Annotated corpora and tools of the PARSEME Shared Task on Automatic Identification of Verbal Multiword Expressions (edition 1.0)

    No full text
    The PARSEME shared task aims at identifying verbal MWEs in running texts. Verbal MWEs include idioms (let the cat out of the bag), light verb constructions (make a decision), verb-particle constructions (give up), and inherently reflexive verbs (se suicider 'to suicide' in French). VMWEs were annotated according to the universal guidelines in 18 languages. The corpora are provided in the parsemetsv format, inspired by the CONLL-U format. For most languages, paired files in the CONLL-U format - not necessarily using UD tagsets - containing parts of speech, lemmas, morphological features and/or syntactic dependencies are also provided. Depending on the language, the information comes from treebanks (e.g., Universal Dependencies) or from automatic parsers trained on treebanks (e.g., UDPipe). This item contains training and test data, tools and the universal guidelines file
