Morphological characterization of starch grains from the genera Triticum and Hordeum in the Iberian Peninsula

ABSTRACT: Starch grains are increasingly used in archaeobotanical studies as markers of diet, plant domestication, tool use and site organization in archaeological research, because their morphology and features provide a means to identify the plant that produced them. In this paper we characterize morphometrically the starch grains of five species of the genus Triticum and three varieties of Hordeum vulgare. In addition there is an assessment of the studies of starch grains made in the Prehistory of the Iberian Peninsula, indicating the achievements, the weaknesses and future directions to promote this type of bioarchaeological analysis; especially, there is a need to rely on wide reference collections, as well as apply statistical analyses and carry out experimental studies to control the processes of alteration of the starch grains.RESUMEN: Los granos de almidón son cada vez más utilizados en los estudios arqueobotánicos como marcadores de la dieta, la domesticación de plantas, el uso de herramientas y la organización microespacial de los yacimientos arqueológicos, debido a que su morfología y características permiten identificar las plantas que los produjeron. En el presente trabajo se caracterizan morfométricamente los granos de almidón de cinco especies del género Triticum y tres variedades de Hordeum vulgare. Además se hace un balance de los estudios de almidones realizados en la Prehistoria de la Península Ibérica, señalando los logros, las debilidades y futuras directrices para potenciar este tipo de análisis bioarqueológico; especialmente la necesidad de contar con amplias colecciones de referencia, la aplicación de análisis estadísticos paralelos, y la realización de estudios experimentales para controlar los procesos de alteración de los almidones

Optimized scheduling of periodic hard real-time multicore systems

[EN] Multicore systems were developed to provide a substantial performance increase over mono-core systems. But shared hardware resources are a problem as they add unpredictable delays that affect the schedulability of multicore hard real-time systems. In recent years much effort has been put into modelling interference and proposing scheduling techniques to mitigate its negative effect. Using one of these models, we propose a scheduling technique, based on Integer Linear Programming (ILP) that, in combination with a task to core allocator, not only achieves a feasible schedule but also reduces the interference produced by shared hardware resources in the context of hard real-time multicore systems. The evaluation shows how interference is reduced (approximate to 83.47%) and schedulability is increased (approximate to 12.25%) compared to traditional heuristics.This work was supported in part by Ministerio de Ciencia e Innovacion (MCIN)/Agencia Estatal de Investigacion (AEI)/10.13039/501100011033 under Grant PLEC2021-007609, in part by the European Union NextGeneration EU/Plan de Recuperacion, Transformaciony Resiliencia (PRTR) [MOBILITY IN THE CITY OF THE FUTURE.

PlanetCam UPV/EHU: a two-channel lucky imaging camera for solar system studies in the spectral range 0.38-1.7 µm

This is an author-created, un-copyedited version of an article published in Publications of the Astronomical Society of the Pacific. IOP Publishing Ltd is not responsible for any errors or omissions in this version of the manuscript or any version derived from it.We present PlanetCam UPV/EHU, an astronomical camera designed fundamentally for high-resolution imaging of Solar System planets using the “lucky imaging” technique. The camera observes in a wavelength range from 380 nm to 1.7 µm and the driving science themes are atmosphere dynamics and vertical cloud structure of Solar System planets. The design comprises two configurations that include one channel (visible wavelengths) or two combined channels (visible and short wave nfrared) working simultaneously at selected wavelengths by means of a dichroic beam splitter. In this paper the camera components for the two configurations are described, as well as camera performance and the different tests done for the precise characterization of its radiometric and astrometric capabilities at high spatial resolution. Finally, some images of solar system objects are presented as well as photometric results and different scientific cases on astronomical targets.Peer ReviewedPostprint (author's final draft

A 12-bit@40MS/s Gm-C Cascade 3-2 Continuous-Time Sigma-Delta Modulator

This paper reports the transistor-level design of a 130-nm CMOS continuous-time cascade ΣΔ modulator. The modulator topology, directly synthesized in the continuous-time domain, consists of a third-order stage followed by a second-order stage, both realized using Gm-C integrators and a 4-bit internal quantizer. Dynamic element matching is included to compensate for the non-linearity of the feedback digital-to-analog converters. The estimated power consumption is 70 mW from a 1.2-V supply voltage when is clocked at 240MHz. CADENCE-SPECTRE simulations show 12-bit effective resolution within a 20-MHz signal bandwidth.This work has been supported by the Spanish Ministry of Science and Education (with support from the European Regional Development Fund) under contract TEC2004-01752/MIC.Peer reviewe

Which region and which sector leads the circular economy? CEBIX, a multivariant index based on business actions

In this research, the two-step composite Circular Economy Business Index was created, based on 17 environmental practices that companies have implemented to reduce the generation of waste and emissions and to increase the reuse and efficiency of materials and energy, among other actions. The use of a sample of 26,783 companies from 49 countries and 10 sectors for the period 2014–2019 allowed the aggregation of these initiatives at the country and industry levels. In this sense, our results show less progress in the circular transformation worldwide and can be used in the design of policies aimed at promoting changes in production and consumption systems in specific geographic or industrial contexts.Junta de Castilla y Leon SA069G18Ministerio de Ciencia, Innovacion y Universidades RTI2018-093423-B-I00Universidad de Salamanca y Junta de Castilla y Leon y Fondo Europeo de Desarrollo Regional CLU-2019-03 Uni-dad de Excelencia "Gestion Economica para la Sostenibilida

Scheduling of hard real-time systems using non-conventional techniques

[EN] In the scheduling of hard real time systems it is key to find a temporal plan in which tasks can be executed before the deadline expires. Different types of scheduling algorithms can be used to achieve this goal. In addition to finding a feasible plan, it is often beneficial, out of all existing feasible plans, to find one that minimises some time parameter of the system. There are many scheduling algorithms that are able to find a correct scheduling of the set of tasks, but it is not so common to find algorithms that optimise other parameters to improve the performance of the system in terms of stability, power consumption, etc. Existing heuristics can improve the performance but without ensuring an optimal result. In this work we explore unconventional scheduling techniques based on integer linear programming to solve scheduling in mono processor systems with the objective of minimising the worst-case response time of the system tasks and the assignment of tasks to processors in multiprocessor systems with the objective of minimising the interference produced by the access to common hardware resources.[ES] En la planificación de sistemas de tiempo real crí­tico es clave encontrar un plan temporal en el que las tareas pueden ejecutarse antes de que venza el plazo establecido. Para lograr este objetivo se pueden utilizar diferentes tipos de algoritmos de planificación. Además de encontrar un plan factible, muchas veces es beneficioso, de todos los planes factibles existentes, encontrar aquel que minimiza algún parámetro temporal del sistema. Existen muchos algoritmos de planificación que son capaces de encontrar una planificación correcta del conjunto de tareas. Pero no es tan común encontrar algoritmos que optimicen otros parámetros para mejorar el funcionamiento del sistemas en términos de estabilidad, consumo de potencia, etc. Los heurí­sticos existentes puede mejorar el comportamiento pero sin asegurar un resultado óptimo. En este trabajo exploramos las técnicas de planificación no convencionales basadas en programación lineal entera para resolver la planificación en sistemas mono procesador con el objetivo de minimizar el peor tiempo de respuesta y el cambio de contexto de las tareas del sistema y la asignación de tareas a procesadores en sistemas multiprocesador con el objetivo de minimizar la interferencia producida por el acceso a recursos hardware comunes.Esta publicacion es parte del proyecto de I+D+i PLEC2021-007609 financiado por MCIN/ AEI/10.13039/501100011033 y por “Unión Europea NextGenerationEU / PRTR”.Balbastre, P.; Aceituno, JM.; Guasque, A.; Blanes, JF.; Crespo, A.; Poza, JL.

How relevant is the place where first-year college students live in relation to the increase in body mass index?

Producción Científica1) Objective: This study analyzes the evolution of the body mass index (BMI) throughout the academic year associated with changes in the lifestyle associated with the place where students live during the course, lifestyle design, and health strategies for the university community. (2) Methods: A total of 93 first-year nursing students participated in this study. Data were collected throughout the course by administering self-reported questionnaires about eating habits and lifestyles, weight, and height to calculate their BMI and place of residence throughout the course. Data were analyzed using statistical analysis (Mann–Whitney, chi-square, Student’s t-test, repeated-measures analysis of variance, and least significant difference tests). (3) Results: We found that the mean BMI increases significantly throughout the course among all students regardless of sex, age, eating habits, or where they live during the course. At the beginning of the course, the mean BMI was 22.10 ± 3.64. The mean difference between the beginning of the course and the middle has a value of p-value < 0.015 and between the middle of the course and the end a p-value < 0.009. The group that increased the most is found among students who continue to live in the family nucleus rather than those who live alone or in residence. Students significantly changed their eating and health habits, especially those who live alone or in residence. (4) Conclusions: There is an increase in BMI among students. It is necessary to carry out seminars or talks that can help students understand the importance of good eating practices and healthy habits to maintain their weight and, therefore, their health, in the short, medium, and long term and acquire a good quality of life.Este trabajo fue apoyado por subvenciones (Grants 2019-GRIN-26896, 2020-GRIN-29192
