Briefing on meetings at & reports by the 65th & 66th United Nations General Assembly

Briefing on meetings at & reports by the 65th & 66th United Nations General AssemblyNo relevant differences are observed or identified after perusal of the space-related resolutions and documents issued by the UN System between 2010 and 2011. The most remarkable statements remain virtually unchanged in this time period. For instance, the UN GA recognizes the common interest of all mankind in the exploration and use of outer space for peaceful purposes, and reaffirms that these shall be carried out for the benefit and in the interest of all countries, irrespective of their degree of development. Also, the growing use of outer space increases the need for greater transparency and better information on the part of the international community. Again in 2011, the UN GA stated that it is deeply convinced of the important role that science and technology play in promoting sustained economic growth and sustainable development and that their use and applications in areas such as telemedicine, tele-education, disaster management, environmental protection and other EO applications, contribute to achieve the objectives in various aspects of economic, social and cultural development and welfare, particularly poverty eradication and mitigation of the consequences of disasters. It is necessary to continue to examine how space science and technology and their applications could contribute to achieve the UN MDG, since space tools are indispensable not only in areas linked to disasters, but also in climate change, food security, opportunities for education and global health. In 2011, 12 April was declared as the International Day of Human Space Flight to celebrate each year at the international level the beginning of the space era for mankind, reaffirming the important contribution of space science and technology in achieving sustainable development goals and increasing the well-being of States and peoples, as well as ensuring the realization of their aspiration to maintain outer space for peaceful purposes. We congratulate SGAC people working on the project YGNSS as their contribution [8] to the 2011 HLS AMR of the UN ECOSOC was accepted for distribution to all participants of the HLS in Geneva, July 2011. In this a written statement, the YNSS team informed the HLS AMR that SGAC “is focused on cultivating the next generation of space leaders and increasing awareness of the educational and societal benefits of space technology” and that “Within SGAC, the project YGNSS aims to present to youth the benefits of GNSS and how various such systems applications are able to benefit a nation’s economy and society”. Also, it is mentioned that “YGNSS has supported the educational outreach of GNSS applications”, that YGNSS has spread “the word that GNSS can be used for precision timing, agricultural and disaster management, and a wide variety of items that need accurate positioning, navigation, and timing”, that YGNSS has recommended “that the international community continue to foster the education of GNSS and the utilities of space technology”. Finally, the written statement informs that SGAC “is committed to providing a network for university students and young professionals in the international space sector to collaborate and contribute their international knowledge and skills to foster development”. As per the report from the IAF GEOSS Workshop, Space Sensors for Climate Monitoring [9], it is worth noting that satellite data are required to effectively monitor, characterize and predict changes in the Earth system, and particularly in the climate. Earth Observation (EO) satellites are essential as they provide the only realistic means to obtain the necessary global coverage. With well-calibrated measurements, e.g. using in situ data, space-based sensors will become a critical contribution to global observations for climate.Preprin

Privacy preserving protocol for detecting genetic relatives using rare variants.

MotivationHigh-throughput sequencing technologies have impacted many areas of genetic research. One such area is the identification of relatives from genetic data. The standard approach for the identification of genetic relatives collects the genomic data of all individuals and stores it in a database. Then, each pair of individuals is compared to detect the set of genetic relatives, and the matched individuals are informed. The main drawback of this approach is the requirement of sharing your genetic data with a trusted third party to perform the relatedness test.ResultsIn this work, we propose a secure protocol to detect the genetic relatives from sequencing data while not exposing any information about their genomes. We assume that individuals have access to their genome sequences but do not want to share their genomes with anyone else. Unlike previous approaches, our approach uses both common and rare variants which provide the ability to detect much more distant relationships securely. We use a simulated data generated from the 1000 genomes data and illustrate that we can easily detect up to fifth degree cousins which was not possible using the existing methods. We also show in the 1000 genomes data with cryptic relationships that our method can detect these individuals.AvailabilityThe software is freely available for download at http://genetics.cs.ucla.edu/crypto/

Sex differences in intimate relationships

Social networks have turned out to be of fundamental importance both for our understanding human sociality and for the design of digital communication technology. However, social networks are themselves based on dyadic relationships and we have little understanding of the dynamics of close relationships and how these change over time. Evolutionary theory suggests that, even in monogamous mating systems, the pattern of investment in close relationships should vary across the lifespan when post-weaning investment plays an important role in maximising fitness. Mobile phone data sets provide us with a unique window into the structure of relationships and the way these change across the lifespan. We here use data from a large national mobile phone dataset to demonstrate striking sex differences in the pattern in the gender-bias of preferred relationships that reflect the way the reproductive investment strategies of the two sexes change across the lifespan: these differences mainly reflect women's shifting patterns of investment in reproduction and parental care. These results suggest that human social strategies may have more complex dynamics than we have tended to assume and a life-history perspective may be crucial for understanding them.Comment: 5 pages, 3 figures, contains electronic supplementary materia

Measuring the progress and impacts of decarbonising British electricity

Britain’s ambitious carbon targets require that electricity be immediately and aggressively decarbonised, so it is reassuring to report that electricity sector emissions have fallen 46% in the three years to June 2016, their lowest since 1960. This paper analyses the factors behind this fall and the impacts they are having. The main drivers are: demand falling 1.3% per year due to efficiency gains and mild winters; gas doubling its share to 60% of fossil generation due to the carbon price floor; and the dramatic uptake of wind, solar and biomass which now supply up to 45% of demand. Accounting conventions also play their part: imported electricity and biomass would add 5% and 2% to emissions if they were included. The pace of decarbonisation is impressive, but raises both engineering and economic challenges. Falling peak demand has delayed fears of capacity shortage, but minimum net demand is instead becoming a problem. The headroom between inflexible nuclear and intermittent renewables is rapidly shrinking, with controllable output reaching a minimum of just 5.9 GW as solar output peaked at 7.1 GW. 2015 also saw Britain’s first negative power prices, the highest winter peak prices for six years, and the highest balancing costs

Quasi-oscillatory dynamics observed in ascending phase of the flare on March 6, 2012

Context. The dynamics of the flaring loops in active region (AR) 11429 are studied. The observed dynamics consist of several evolution stages of the flaring loop system during both the ascending and descending phases of the registered M-class flare. The dynamical properties can also be classified by different types of magnetic reconnection, related plasma ejection and aperiodic flows, quasi-periodic oscillatory motions, and rapid temperature and density changes, among others. The focus of the present paper is on a specific time interval during the ascending (pre-flare) phase. Aims. The goal is to understand the quasi-periodic behavior in both space and time of the magnetic loop structures during the considered time interval. Methods.We have studied the characteristic location, motion, and periodicity properties of the flaring loops by examining space-time diagrams and intensity variation analysis along the coronal magnetic loops using AIA intensity and HMI magnetogram images (from the Solar Dynamics Observatory(SDO)). Results. We detected bright plasma blobs along the coronal loop during the ascending phase of the solar flare, the intensity variations of which clearly show quasi-periodic behavior. We also determined the periods of these oscillations. Conclusions. Two different interpretations are presented for the observed dynamics. Firstly, the oscillations are interpreted as the manifestation of non-fundamental harmonics of longitudinal standing acoustic oscillations driven by the thermodynamically nonequilibrium background (with time variable density and temperature). The second possible interpretation we provide is that the observed bright blobs could be a signature of a strongly twisted coronal loop that is kink unstable.Comment: 12 pages, 10 figures, A&A, in pres
