Application of Things: A Step beyond Web of Things

Internet of Things has achieved a great expectation in the last few years, largely due to possibilities in the field of the interaction between user and environment. This interaction allows users to get involved in their environments, managing at all times each item that surrounds them. Specially, because of complex services delivered by surrounding item, increasingly it is necessary to help users to choose what services are offered and what are theirs functionalities. Is this paper, is presented a new approach to the human-items interaction by using the concept of Internet of Things. In this way, the user can not only run the different applications offers by smart-things, but to share theirs results through many social networks and allows the remote execution of services provided by the own user and his/her social environment. Furthermore, a structure will be defined to assure the best user comfort when information sharing between the device and the environments was needed.Ministerio de Ciencia e Innovación TIN2009-14378-C02-0

Electric and magnetic dipole strength in ⁵⁸Ni from forward-angle proton scattering

Background: Electric and magnetic dipole strengths in nuclei at excitation energies well below the giant resonance region are of interest for a variety of nuclear structure problems including a possible electric dipole toroidal mode or the quenching of spin-isospin flip modes. Purpose: The aim of the present work is a state-by-state analysis of possible ⁢1 and ⁢1 transitions in 58Ni with a high-resolution (,′) experiment at 295 MeV and very forward angles including 0∘ and a comparison to results from studies of the dipole strength with the (,′) and (,′) reactions. Methods: The ⁢1 and ⁢1 cross sections of individual peaks in the spectra are deduced with a multipole decomposition analysis (MDA). They are converted to reduced ⁢1 and spin ⁢1 transition strengths using the virtual photon method of relativistic Coulomb excitation and the unit cross-section method, respectively. The experimental ⁢1 strength distribution is compared to large-scale shell-model calculations with the effective GXPF1A and KB3G interactions. Results: In total, 11 ⁢1 and 26 ⁢1 transitions could be uniquely identified in the excitation energy region 6–13 MeV. In addition, 22 dipole transitions with preference for either ⁢1 or ⁢1 multipolarity and 57 transitions with uncertain multipolarity were found. Despite the high level density good agreement is obtained for the deduced excitation energies of =1 states in the three types of experiments indicating that the same states are excited. The ⁡(⁢1) and ⁡(⁢1) strengths deduced in the (,′) experiments are systematically smaller than in the present work because of the lack of information on branching ratios to lower-lying excited states and the competition of particle emission. Fair agreement with the ⁡(⁢1) strengths extracted from the (,′) data is obtained after removal of ⁢1 transitions uniquely assigned in the present work belonging to a low-energy toroidal mode with unusual properties mimicking ⁢1 excitations in electron scattering. The shell-model calculations provide a good description of the isospin splitting and the running sum of the ⁢1 strength. A quenching factor 0.74 for the spin-isospin part of the ⁢1 operator is needed to attain quantitative agreement with the data. Conclusions: High-resolution forward-angle inelastic proton scattering experiments at beam energies of about 300 MeV are a highly selective tool for an extraction of resolved ⁢1 and ⁢1 strength distributions in medium-mass nuclei. Fair agreement with results from electron scattering experiments is obtained indicating a dominance of spin contributions to the ⁢1 strength. Shell-model calculations are in good agreement with gross properties of the ⁢1 strength distribution when a quenching factor for the spin-isospin part comparable to the one needed for a description of Gamow-Teller (GT) strength is included

Electric dipole polarizability of 40^{40}Ca

The electric dipole strength distribution in $^{40}$Ca between 5 and 25 MeV has been determined at RCNP, Osaka, from proton inelastic scattering experiments at very forward angles. Combined with total photoabsorption data at higher excitation energy, this enables an extraction of the electric dipole polarizability $\alpha_\mathrm{D}$($^{40}$Ca) = 1.92(17) fm$^3$. Together with the measured $\alpha_{\rm D}$ in $^{48}$Ca, it provides a stringent test of modern theoretical approaches, including coupled cluster calculations with chiral effective field theory interactions and state-of-the art energy density functionals. The emerging picture is that for this medium-mass region dipole polarizabilities are well described theoretically, with important constraints for the neutron skin in $^{48}$Ca and related equation of state quantities.Comment: 6 pages, 3 figure

A novel Munc13-4/S100A10/annexin A2 complex promotes Weibel–Palade body exocytosis in endothelial cells

Endothelial cells respond to blood vessel injury by the acute release of the procoagulant von Willebrand factor, which is stored in unique secretory granules called Weibel-Palade bodies (WPBs). Stimulated WPB exocytosis critically depends on their proper recruitment to the plasma membrane, but factors involved in WPB-plasma membrane tethering are not known. Here we identify Munc13-4, a protein mutated in familial hemophagocytic lymphohistiocytosis 3, as a WPB-tethering factor. Munc13-4 promotes histamine-evoked WPB exocytosis and is present on WPBs, and secretagogue stimulation triggers an increased recruitment of Munc13-4 to WPBs and a clustering of Munc13-4 at sites of WPB-plasma membrane contact. We also identify the S100A10 subunit of the annexin A2 (AnxA2)-S100A10 protein complex as a novel Munc13-4 interactor and show that AnxA2-S100A10 participates in recruiting Munc13-4 to WPB fusion sites. These findings indicate that Munc13-4 supports acute WPB exocytosis by tethering WPBs to the plasma membrane via AnxA2-S100A10

Mid‐ to late Holocene environmental changes and human‐environment interactions in the surroundings of La Silla del Papa, SW Spain

International audienceIn southern Iberia, the surroundings of the Strait of Gibraltar are known as a crossroad for population movements, cultural exchanges, and trade from Late Prehistory to modern times. However, questions remain about the impact of this historical development on the environment. The settlement of La Silla del Papa, an important hillfort in southern Andalusia (Cádiz), was occupied during the entire Iron Age, replaced by the coastal town Baelo Claudia during Roman times, and reoccupied during Early Medieval times. As such, La Silla del Papa and its territory represent an ideal location for long-term studies on human-environment interactions. Within the framework of the interdisciplinary project "Archeostraits," geoarchaeological investigations in the surroundings of La Silla del Papa aimed at constraining ecological conditions and human-environment interactions during the This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes

Weapons, fighters and combat: spears and swords in Early Bronze Age Scandinavia

This article deals with the use-wear analysis of 204 weapons of Period I of the Early Nordic Bronze Age. The analysed sample contained 154 spearheads and 50 swords and was made up of approximately one-third of the contemporaneous weapons in Southern Scandinavia. The use-wear analysis was undertaken with a source critical view on corrosion and other taphonomic processes. The information obtained was used to see how use-wear and taphonomic processes influence each other. Use-wear analysis was employed to evaluate statements regarding the functionality, or rather non-functionality, of Early Bronze Age weaponry. According to the results, spears and swords were not only functional but also very frequently used. Further deductions can be made from the material. Despite a difference in the scale of fighting, spears and swords show essentially the same kind of combat wear. It is argued that this relates to essentially similar styles of fighting that employ both cutting and stabbing movements and are perhaps most appropriately termed ‘fencing’. This style of fighting possibly emerged from frequent encounters of sword and spear fighters in the closely interconnected world of Southern Scandinavia during Period I of the Early Bronze Age. In these engagements, a partial homogenising effect of warfare and fighting becomes visible. Yet, it is not the only effect that accompanies combat and war. Diversification and homogenisation are not mutually exclusive or contradictive. Accordingly, they took place simultaneously and helped develop fighting styles and weapon technologies
