Methods for autonomous wristband placement with a search-and-rescue aerial manipulator

A new robotic system for Search And Rescue (SAR) operations based on the automatic wristband placement on the victims’ arm, which may provide identification, beaconing and remote sensor readings for continuous health monitoring. This paper focuses on the development of the automatic target localization and the device placement using an unmanned aerial manipulator. The automatic wrist detection and localization system uses an RGB-D camera and a convolutional neural network based on the region faster method (Faster R-CNN). A lightweight parallel delta manipulator with a large workspace has been built, and a new design of a wristband in the form of a passive detachable gripper, is presented, which under contact, automatically attaches to the human, while disengages from the manipulator. A new trajectory planning method has been used to minimize the torques caused by the external forces during contact, which cause attitude perturbations. Experiments have been done to evaluate the machine learning method for detection and location, and for the assessment of the performance of the trajectory planning method. The results show how the VGG-16 neural network provides a detection accuracy of 67.99%. Moreover, simulation experiments have been done to show that the new trajectories minimize the perturbations to the aerial platform.Universidad de Málaga.

Efectos del déficit hídrico en el color de la baya y del vino, en la variedad de uva Cabernet sauvignon. Madrid.

Existe una preocupación por las consecuencias que puede ocasionar a la viticultura el cambio climático, especialmente en zonas cálidas y secas. Estos cambios podrían tener importantes consecuencias tanto en la calidad de la uva como en el potencial de sus vinos. El objetivo del ensayo fue evaluar los efectos del déficit hídrico en el color de los vinos, ya que hoy en día resulta de carácter obligatorio mantener su intensidad y calidad constante, frente a la percepción del consumidor frente a un vino de calidad. El diseño experimental se llevó a cabo en un viñedo comercial de la variedad Cabernet sauvignon, en el Sureste de Madrid, en los años 2010 y 2011. Los tratamientos fueron: i) déficit moderado continuo, (T0,45- 0,6), ii) déficit severo continuo (T0-0,3), iii) déficit severo post-envero (T0,45-0,3), iv) déficit severo pre-envero (T0-0,6). El déficit hídrico sí influyó en el tamaño de la baya, pero no a los porcentajes de hollejo, pulpa y semilla. Los vinos resultantes de los tratamientos con menor déficit obtuvieron las mayores tasas de color rojo y amarillo, luminosidad y cromaticidad

Smart lanthanide antennas for sensing water

Two new families of lanthanide antennas are described. 8-Methoxy- 4,5-dihydrocyclopenta[de]quinolin-2(1H)-one phosphonates or carboxylates behave as selective antennas exhibiting Eu3+ luminescence in organic solvents, while quinolin-2(1H)-one analogues selectively sensitize the Tb3+ emission. These emissions are quenched by H2O addition. Based on this behaviour, the new lanthanide antennas can be used as highly sensitive water sensors.Spanish Ministerio de Economia y Competividad SAF2012-32209 FU2015-67284-RMinisterio de Ciencia e Innovacion/Agencia Estatal de Investigacion/European Regional Development Fund CTQ2017-85658-R CTQ2015-63997-C2Consejo Superior de Investigaciones Cientificas (CSIC) 201580E07

Transient Hemolytic Anemia after Transjugular Intrahepatic Portosystemic Stent Shunt

Management of variceal bleeding secondary to portal hypertension constitutes a challenging issue, particularly in child's C cirrhotic patients. Recently, transjugular placement of self-expanding metallic stents in the liver (TIPS), creating a shunt between the portal and hepatic branches has provided a safe and promising therapeutic approach in this clinical situation. We report here the case of a 66-year-old male cirrhotic patient who developed a moderately severe clinical picture of a Coombsnegative hemolytic anemia (serum hemoglobin, 93 g/l, serum bilirubin 160.74 umol/L (9.4 mg/dl), indirect 6.3 mg/dl (107.73 umol/L); serum LDH 1220 u/l, reticulocytes, 5.1%. serum ferritin, 1221 ug/1, schistocytes in peripheral blood smear) the week after undergoing a TIPS, suggesting the development ofa microangiopathic hemolytic anaemia secondary to red blood cell disruption by passing through the metallic network of the stent

A Review of Virtual Inertia Techniques for Renewable Energy-Based Generators

Over recent decades, the penetration of renewable energy sources (RES), especially photovoltaic and wind power plants, has been promoted in most countries. However, as these both alternative sources have power electronics at the grid interface (inverters), they are electrically decoupled from the grid. Subsequently, stability and reliability of power systems are compromised. Inertia in power systems has been traditionally determined by considering all the rotating masses directly connected to the grid. Thus, as the penetration of renewable units increases, the inertia of the power system decreases due to the reduction of directly connected rotating machines. As a consequence, power systems require a new set of strategies to include these renewable sources. In fact, ‘hidden inertia,’ ‘synthetic inertia’ and ‘virtual inertia’ are terms currently used to represent an artificial inertia created by inverter control strategies of such renewable sources. This chapter reviews the inertia concept and proposes a method to estimate the rotational inertia in different parts of the world. In addition, an extensive discussion on wind and photovoltaic power plants and their contribution to inertia and power system stability is presented

Linking the impact of bacteria on phytoplankton growth with microbial community composition and co-occurrence patterns

The interactions between microalgae and bacteria have recently emerged as key control factors which might contribute to a better understanding on how phytoplankton communities assemble and respond to environmental disturbances. We analyzed partial 16S rRNA and 18S rRNA genes from a total of 42 antibiotic bioassays, where phytoplankton growth was assessed in the presence or absence of an active bacterial community. A significant negative impact of bacteria was observed in 18 bioassays, a significant positive impact was detected in 5 of the cases, and a non-detectable effect occurred in 19 bioassays. Thalasiossira spp., Chlorophytes, Vibrionaceae and Alteromonadales were relatively more abundant in the samples where a positive effect of bacteria was observed compared to those where a negative impact was observed. Phytoplankton diversity was lower when bacteria negatively affect their growth than when the effect was beneficial. The phytoplankton-bacteria co-occurrence subnetwork included many significant Chlorophyta-Alteromonadales and Bacillariophyceae-Alteromonadales positive associations. Phytoplankton-bacteria co-exclusions were not detected in the network, which contrasts with the negative effect of bacteria on phytoplankton growth frequently detected in the bioassays, suggesting strong competitive interactions. Overall, this study adds strong evidence supporting the key role of phytoplanktonbacteria interactions in the microbial communities.Agencia Estatal de Investigación | Ref.

Developing a new innovative methodology to integrate geophysical techniques into characterization of potential CO2 storage sites: Lopín structure (Southern Ebro basin, Spain)

Abstract:One of the main challenges facing geological storage is to identify cost-effective methodologicalworkflows for characterizing and monitoring geological storage sites. In the framework of the ALGECO2 pro-ject, led by the IGME (Geological and Mining Institute, Spain), a preliminary study of the Lopín site in the NEof Spain indicated conditions were promising for geological storage of CO2. However, the poor quality of thelegacy seismic reflection data precluded thorough characterization. Within the H2020 PilotSTRATEGY pro-ject, one of the possible selected target reservoirs was the Lopín structure. In order to characterize its geometryand physical properties as required to properly evaluate its storage potential, IGME applied a new emergingmethodology that integrates reinterpreted reflection seismic data with newly acquired and interpreted gravity,passive seismic and petrophysical data. This methodology was successfully applied along one seismic profile. Inthis paper, we present the results of this integration as thefirst step towards characterizing the site and evaluatingits suitability for storage.Funding for this research came from the Horizon 2020 Framework Programme (European Climate,Infrastructure and Environment Executive Agency (CINEA), award 101022664

Association of the MYH9 gene polymorphisms with chronic renal disease secondary to hypertensive nephrosclerosis, in a Caucasian population

Background: Hypertensive nephrosclerosis (HN) is a chronic kidney disease (CKD) associated to essential hypertension, but their causal relationship is controversial. New evidence suggests that MYH9 gene alterations are associated with HN in African Americans. The aim of this study is to investigate the role of this gene in Spanish Caucasians. Methods: We compare high-risk MYH9 variants of patients with HN recruited according to standard clinical criteria (CKD stages 3-5), with essential hypertensives without renal disease (estimated glomerular filtration rate (eGFR) > 60 ml/min/1,73m2 and albuminuria < 300 mg/g creatinine), and also CKD patients with HN and progressive impairment of renal function with those who were stable. Diabetics were excluded. Results: A blood sample was obtained for genetic study of 238 patients with HN-CKD and 233 hypertensive controls. The rs3752462-T and rs4821480-T (risk alleles for CKD) were more frequent in the CKD group, but without significant difference. We found no differences for these SPNs with blood pressure, creatinine, albuminuria or renal disease progression. Conclusions: The effect of two common MYH9 single nucleotide polymorphisms (SPNs) on the development of CKD secondary to HN in our Spanish Caucasian population is low or zero; in any case less than that found in other, mainly African Americans.Funding: This work was supported by grant Red de Investigación Renal-REDINREN from the Instituto Carlos III, and with funds from the Fundación Renal Iñigo Álvarez de Toledo (Iñigo Álvarez de Toledo Kidney Foundation) in the Molecular Genetics Grou
