The emission from GRBs comprises a short (typically tens of seconds) and bright prompt emission, followed by a much longer afterglow phase. During the afterglow phase, the shocked outflow-produced by the interaction between the ejected matter and the circumburst medium-slows down, and a gradual decrease in brightness is observed(2). GRBs typically emit most of their energy via.-rays with energies in the kiloelectronvolt-to-megaelectronvolt range, but a few photons with energies of tens of gigaelectronvolts have been detected by space-based instruments(3). However, the origins of such high-energy (above one gigaelectronvolt) photons and the presence of very-high-energy (more than 100 gigaelectronvolts) emission have remained elusive(4). Here we report observations of very-high-energy emission in the bright GRB 180720B deep in the GRB afterglow-ten hours after the end of the prompt emission phase, when the X-ray flux had already decayed by four orders of magnitude. Two possible explanations exist for the observed radiation: inverse Compton emission and synchrotron emission of ultrarelativistic electrons. Our observations show that the energy fluxes in the X-ray and gamma-ray range and their photon indices remain comparable to each other throughout the afterglow. This discovery places distinct constraints on the GRB environment for both emission mechanisms, with the inverse Compton explanation alleviating the particle energy requirements for the emission observed at late times. The late timing of this detection has consequences for the future observations of GRBs at the highest energies.}, language = {en} } @article{AbdallaAdamAharonianetal.2019, author = {Abdalla, Hassan E. and Adam, R. and Aharonian, Felix A. and Benkhali, F.

During two periods of high activity in April 2014 and June 2015 target-of-opportunity observations were undertaken with the High Energy Stereoscopic System (H.E.S.S.) in the very-high-energy (VHE, E > 100 GeV) gamma-ray domain. While the observation in 2014 provides an upper limit, the observation in 2015 results in a signal with 8 : 7 sigma significance above an energy threshold of 66 GeV. No VHE variability was detected during the 2015 observations. The VHE photon spectrum is soft and described by a power-law index of 4.2 +/- 0.3. The H.E.S.S. data along with a detailed and contemporaneous multiwavelength data set provide constraints on the physical parameters of the emission region. The minimum distance of the emission region from the central black hole was estimated using two plausible geometries of the broad-line region and three potential intrinsic spectra. The emission region is confidently placed at r greater than or similar to 1 : 7 X 1017 cm from the black hole, that is beyond the assumed distance of the broad-line region. Time-dependent leptonic and lepto-hadronic one-zone models were used to describe the evolution of the 2015 flare. Neither model can fully reproduce the observations, despite testing various parameter sets.

Additionally, responses to land use can differ greatly among different organisms; therefore, overall effects of land-use on total local biodiversity are hardly known. To test for effects of LUI (quantified as the combined intensity of fertilization, grazing, and mowing) and interannual variation in LUI (SD in LUI across time), we introduce a unique measure of whole-ecosystem biodiversity, multidiversity. This synthesizes individual diversity measures across up to 49 taxonomic groups of plants, animals, fungi, and bacteria from 150 grasslands. Multidiversity declined with increasing LUI among grasslands, particularly for rarer species and aboveground organisms, whereas common species and belowground groups were less sensitive. However, a high level of interannual variation in LUI increased overall multidiversity at low LUI and was even more beneficial for rarer species because it slowed the rate at which the multidiversity of rare species declined with increasing LUI. In more intensively managed grasslands, the diversity of rarer species was, on average, 18\% of the maximum diversity across all grasslands when LUI was static over time but increased to 31\% of the maximum when LUI changed maximally over time. In addition to decreasing overall LUI, we suggest varying LUI across years as a complementary strategy to promote biodiversity conservation.}, language = {en} } @article{BanksNishiyamaHasebeetal.2011, author = {Banks, Jo Ann and Nishiyama, Tomoaki and Hasebe, Mitsuyasu and Bowman, John L. and Gribskov, Michael and dePamphilis, Claude and Albert, Victor A. and Aono, Naoki and Aoyama, Tsuyoshi and Ambrose, Barbara A. and Ashton, Neil W. and Axtell, Michael J. and Barker, Elizabeth and Barker, Michael S. and Bennetzen, Jeffrey L. and Bonawitz, Nicholas D. and Chapple, Clint and Cheng, Chaoyang and Correa, Luiz Gustavo Guedes and Dacre, Michael and DeBarry, Jeremy and Dreyer, Ingo and Elias, Marek and Engstrom, Eric M. and Estelle, Mark and Feng, Liang and Finet, Cedric and Floyd, Sandra K. and Frommer, Wolf B. and Fujita, Tomomichi and Gramzow, Lydia and Gutensohn, Michael and Harholt, Jesper and Hattori, Mitsuru and Heyl, Alexander and Hirai, Tadayoshi and Hiwatashi, Yuji and Ishikawa, Masaki and Iwata, Mineko and Karol, Kenneth G. and Koehler, Barbara and Kolukisaoglu, Uener and Kubo, Minoru and Kurata, Tetsuya and Lalonde, Sylvie and Li, Kejie and Li, Ying and Litt, Amy and Lyons, Eric and Manning, Gerard and Maruyama, Takeshi and Michael, Todd P. and Mikami, Koji and Miyazaki, Saori and Morinaga, Shin-ichi and Murata, Takashi and M{\"u}ller-R{\"o}ber, Bernd and Nelson, David R. and Obara, Mari and Oguri, Yasuko and Olmstead, Richard G. and Onodera, Naoko and Petersen, Bent Larsen and Pils, Birgit and Prigge, Michael and Rensing, Stefan A. and Mauricio Riano-Pachon, Diego and Roberts, Alison W. and Sato, Yoshikatsu and Scheller, Henrik Vibe and Schulz, Burkhard and Schulz, Christian and Shakirov, Eugene V. and Shibagaki, Nakako and Shinohara, Naoki and Shippen, Dorothy E. and Sorensen, Iben and Sotooka, Ryo and Sugimoto, Nagisa and Sugita, Mamoru and Sumikawa, Naomi and Tanurdzic, Milos and Theissen, Guenter and Ulvskov, Peter and Wakazuki, Sachiko and Weng, Jing-Ke and Willats, William W.

By comparing gene content in evolutionarily diverse taxa, we found that the transition from a gametophyte- to a sporophyte-dominated life cycle required far fewer new genes than the transition from a nonseed vascular to a flowering plant, whereas secondary metabolic genes expanded extensively and in parallel in the lycophyte and angiosperm lineages.

In search of dimerizing regions of occludin, dimerization of its cytosolic C-terminal coiled-coil domain was identified. In claudin-5, the second extracellular loop was detected as a dimer.

Based on the recently revised absolute axial configuration of the parent phenylanthraquinones, knipholone and knipholone anthrone, the new dimers were attributed to possess the P- configuration (i.e., with the acetyl portions below the anthraquinone plane) at both axes in the case of joziknipholone A, whereas in joziknipholone B, the knipholone part was found to be M-configured.

This is in striking contrast with traditional conceptual models of rifting and rifted margin formation, which often assume 2-D deformation where the rift velocity is oriented perpendicular to the plate boundary. Here we quantify the validity of this assumption by analysing the kinematics of major continent-scale rift systems in a global plate tectonic reconstruction from the onset of Pangea breakup until the present day. We evaluate rift obliquity by joint examination of relative extension velocity and local rift trend using the script-based plate reconstruction software pyGPlates. Our results show that the global mean rift obliquity since 230 Ma amounts to 34 degrees with a standard deviation of 24 degrees, using the convention that the angle of obliquity is spanned by extension direction and rift trend normal. We find that more than similar to 70 \% of all rift segments exceeded an obliquity of 20 degrees demonstrating that oblique rifting should be considered the rule, not the exception. In many cases, rift obliquity and extension velocity increase during rift evolution (e.g. Australia-Antarctica, Gulf of California, South Atlantic, India-Antarctica), which suggests an underlying geodynamic correlation via obliquity-dependent rift strength. Oblique rifting produces 3-D stress and strain fields that cannot be accounted for in simplified 2-D plane strain analysis. We therefore highlight the importance of 3-D approaches in modelling, surveying, and interpretation of most rift segments on Earth where oblique rifting is the dominant mode of deformation.}, language = {en} }
