Association between birthweight and later body mass index: an individual-based pooled analysis of 27 twin cohorts participating in the CODATwins project
(Oxford University Press, 2017-10)
Background: There is evidence that birthweight is positively associated with body mass
index (BMI) in later life, but it remains unclear whether this is explained by genetic factors
or the intrauterine environment. We ...
Detecting the presence-absence of bluefin tuna by automated analysis of medium-range sonars on fishing vessels
(Public Library Science, 2017-02-02)
This study presents a methodology for the automated analysis of commercial medium range sonar signals for detecting presence/absence of bluefin tuna (Tunnus thynnus) in the Bay of Biscay. The approach uses image processing ...
Novel control algorithm for MPPT with Boost converters in photovoltaic systems
(Elsevier, 2017-07)
The great advances in efficiency and performance of photovoltaic modules would not be very useful if they do not work close to their maximum power point (MPP). In this paper a novel Sliding Mode Control (SMC) based algorithm ...
Contributions of Bottom-Up Energy Transitions in Germany: A Case Study Analysis
(MDPI, 2017-04)
Within the context of an energy transition towards achieving a renewable low-impact energy consumption system, this study analyses how bottom-up initiatives can contribute to state driven top-down efforts to achieve the ...
Microtab design and implementation on a 5MW wind turbine
(MDPI, 2017-05-24)
Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ...
Paleoenvironmental and Paleoclimatic approach to the Late Pleistocene site of Artazu (Arrasate, Northern Iberian Peninsula) using small vertebrates
(Asociación Paleontológica Argentina, 2017-04-20)
The Artazu VII site (Arrasate, northern Iberian Peninsula) is a fossiliferous deposit that was discovered unsystematically at the Kobate Quarry in 2012. During the following year, all the vertebrate remains attributed to ...
Isotopic evidence for the reconstruction of diet and mobility during village formation in the Early Middle Ages: Las Gobas (Burgos, northern Spain)
(Springer, 2017-07-10)
Strontium, carbon, and nitrogen isotopes of human bone and tooth remains have been used to reconstruct residential mobility and diet of early medieval populations at Las Gobas from the sixth to eleventh centuries. Most ...
Middle Pleistocene protein sequences from the rhinoceros genus Stephanorhinus and the phylogeny of extant and extinct Middle/Late Pleistocene Rhinocerotidae
(PeerJ Inc., 2017-03-14)
Ancient protein sequences are increasingly used to elucidate the
phylogenetic relationships between extinct and extant mammalian taxa. Here, we
apply these recent developments to Middle Pleistocene bone specimens of ...
