    Compute and memory demands of state-of-the-art deep learning methods are still a shortcoming that must be addressed to make them useful at IoT end-nodes. In particular, recent results depict a hopeful prospect for image processing using Convolutional Neural Netwoks, CNNs, but the gap between software and hardware implementations is already considerable for IoT and mobile edge computing applications due to their high power consumption. This proposal performs low-power and real time deep learning-based multiple object visual tracking implemented on an NVIDIA Jetson TX2 development kit. It includes a camera and wireless connection capability and it is battery powered for mobile and outdoor applications. A collection of representative sequences captured with the on-board camera, dETRUSC video dataset, is used to exemplify the performance of the proposed algorithm and to facilitate benchmarking. The results in terms of power consumption and frame rate demonstrate the feasibility of deep learning algorithms on embedded platforms although more effort to joint algorithm and hardware design of CNNs is needed.Comment: This work has been submitted to the IEEE for possible publication.

    The centrifugal distortion constants for 0-CH₂ -CH₂ -C = 0 were calculated using Dowling and Watson’s formalisms. From the fitting analysis and the deviation of predicted transitions it is concluded that the second formalism must be adopted. For the different parameters we have: A'=12406.012 ±0.005 MHz; B'=5244.456 ± 0.002 MHz; C'=3869.191 ± 0.002 MHz; dj= -2.08± 0 .05 kHz; djk= -23.6 3± 0.95 kHz; dk= - 33.43 ± 1.69 kHz; dWJ= (0.56± 0.01)X l0-6; dwK = (5.08 ± 0.22)X 10 -6.Publicado on line en 2014.Facultad de Ciencias Exacta

    A newly discovered muscle: The tensor of the vastus intermedius

    The quadriceps femoris is traditionally described as a muscle group composed of the rectus femoris and the three vasti. However, clinical experience and investigations of anatomical specimens are not consistent with the textbook description. We have found a second tensor-like muscle between the vastus lateralis (VL) and the vastus intermedius (VI), hereafter named the tensor VI (TVI). The aim of this study was to clarify whether this intervening muscle was a variation of the VL or the VI, or a separate head of the extensor apparatus. Twenty-six cadaveric lower limbs were investigated. The architecture of the quadriceps femoris was examined with special attention to innervation and vascularization patterns. All muscle components were traced from origin to insertion and their affiliations were determined. A TVI was found in all dissections. It was supplied by independent muscular and vascular branches of the femoral nerve and lateral circumflex femoral artery. Further distally, the TVI combined with an aponeurosis merging separately into the quadriceps tendon and inserting on the medial aspect of the patella. Four morphological types of TVI were distinguished: Independent-type (11/26), VI-type (6/26), VL-type (5/26), and Common-type (4/26). This study demonstrated that the quadriceps femoris is architecturally different from previous descriptions: there is an additional muscle belly between the VI and VL, which cannot be clearly assigned to the former or the latter. Distal exposure shows that this muscle belly becomes its own aponeurosis, which continues distally as part of the quadriceps tendon

    SparkFlow : towards high-performance data analytics for Spark-based genome analysis

    The recent advances in DNA sequencing technology triggered next-generation sequencing (NGS) research in full scale. Big Data (BD) is becoming the main driver in analyzing these large-scale bioinformatic data. However, this complicated process has become the system bottleneck, requiring an amalgamation of scalable approaches to deliver the needed performance and hide the deployment complexity. Utilizing cutting-edge scientific workflows can robustly address these challenges. This paper presents a Spark-based alignment workflow called SparkFlow for massive NGS analysis over singularity containers. SparkFlow is highly scalable, reproducible, and capable of parallelizing computation by utilizing data-level parallelism and load balancing techniques in HPC and Cloud environments. The proposed workflow capitalizes on benchmarking two state-of-art NGS workflows, i.e., BaseRecalibrator and ApplyBQSR. SparkFlow realizes the ability to accelerate large-scale cancer genomic analysis by scaling vertically (HyperThreading) and horizontally (provisions on-demand). Our result demonstrates a trade-off inevitably between the targeted applications and processor architecture. SparkFlow achieves a decisive improvement in NGS computation performance, throughput, and scalability while maintaining deployment complexity. The paper’s findings aim to pave the way for a wide range of revolutionary enhancements and future trends within the High-performance Data Analytics (HPDA) genome analysis realm.Postprin

    Evaluación de las solicitudes “irregulares” de dispensación en farmacia comunitaria

    Conocer el perfil de los pacientes que solicitan medicamentos en la farmacia sin presentar la correspondiente receta, evaluar las causas por las que los demandan. Cuantificar en qué casos, según criterio del farmacéutico, el medicamento podría ser dispensable. Estudio descriptivo transversal que se realizó en dos farmacias comunitarias de A Coruña durante la primera semana de agosto de 2010. Se define como solicitud irregular de dispensación la petición por parte de un paciente de un medicamento que requiere receta, sin presentar dicho documento en el momento en que realiza la solicitud. Se analizaron las solicitudes irregulares de dispensación de medicamentos que necesitan receta sin presentarla. Se registraron un total de 2.055 solicitudes de dispensación, 179 de las cuales fueron irregulares, lo que supone un 8,71% de las solicitudes totales de medicamentos de prescripción. 33 (18,44%) conocían la necesidad de receta para adquirir el medicamento y 146 (81,56%) decían desconocerlo. 158 (88,27%) de las solicitudes irregulares de dispensación serían dispensables según criterio profesional farmacéutico, considerándose no justificada la dispensación en veintiún casos (11,73%). Siguiendo un criterio estrictamente profesional y ético, y teniendo en consideración las contradicciones y paradojas que la legislación presenta, se considera que la mayor parte de las demandas irregulares están justificadas y, por lo tanto, se realiza la dispensación. Deben producirse cambios legislativos que incrementen la capacidad y la responsabilidad del farmacéutico comunitario en la resolución de estas situaciones

    Basic income opportunities in latin america in the face of the covid-19 pandemic: Social vulnerability and structural blocks

    Get PDF
    Frente a la pandemia del COVID19, los gobiernos de América Latina han tomado medidas que tienen y tendrán un profundo impacto económico y social. Si bien muchas de estas medidas mitigan parte del costo inmedia- to de la pandemia y de las estrategias epidemiológicas para su contención, las mismas pueden terminar potenciando las vulnerabilidades de la estructura social y los déficits de los sistemas de protección social. En este escenario se observa el crecimiento del debate de propuestas como el ingreso ciudadano o renta básica. Pese a que sería deseable su implementación, no hay muchas posibilidades en el corto plazo porque la misma depende de cambios en la percepción de las elites, de la inversión para superar los déficits estructurales en la provisión de bienes públicos y de la transformación de las concepciones que sostiene a las actuales políticas de transferencias monetarias focalizadas y condicionadas.Faced with the COVID19 pandemic, the Latin American governments have taken measures that have and will have a profound economic and social impact. While many of this measures might mitigate the socioeconomic impact of the pandemic and of the epidemiological strategies to contain its spread they might end up enhancing the vulnerabilities of the social structure and the deficits of the social protection systems. In this scenario, the debate on proposals such as citizen income or basic income is growing. Although its implementation would be desirable, there are not many possibilities in the short term because it depends on changes in the perception of elites, investment to overcome structural deficits in the provision of public goods and the transformation of conceptions that supports the current policies of targeted and conditional cash transfers.Universidad Pablo de Olavid
