Agreement on Access and Benefit-sharing for Academic Research: A toolbox for drafting Mutually Agreed Terms for access to Genetic Resources and to Associated Traditional Knowledge and Benefit-sharing
This manual contains a set of model clauses that enables users and providers of genetic resources and associated traditional knowledge to set up a legal contract that is adapted to the individual academic research situation. If mutually negotiated and agreed upon by the involved partners this agreement can yield a âMutually Agreed Termsâ ABS contract
Multidifferential study of identified charged hadron distributions in -tagged jets in proton-proton collisions at 13 TeV
Jet fragmentation functions are measured for the first time in proton-proton
collisions for charged pions, kaons, and protons within jets recoiling against
a boson. The charged-hadron distributions are studied longitudinally and
transversely to the jet direction for jets with transverse momentum 20 GeV and in the pseudorapidity range . The
data sample was collected with the LHCb experiment at a center-of-mass energy
of 13 TeV, corresponding to an integrated luminosity of 1.64 fb. Triple
differential distributions as a function of the hadron longitudinal momentum
fraction, hadron transverse momentum, and jet transverse momentum are also
measured for the first time. This helps constrain transverse-momentum-dependent
fragmentation functions. Differences in the shapes and magnitudes of the
measured distributions for the different hadron species provide insights into
the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any

Study of the decay
The decay is studied

state observed at the BaBar and Belle experiments is
resolved into two narrower states, and ,
whose masses and widths are measured to be where the first uncertainties are statistical and the second
systematic. The results are consistent with a previous LHCb measurement using a
prompt sample. Evidence of a new

uncertainty is statistical, the second systematic and the third originates from
the branching fractions of charm hadron decays.Comment: All figures and tables, along with any supplementary material and

sample of proton-proton collision data corresponding to 3.0 fb of
integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The

Resilient State Estimation in Presence of Severe Coordinated Cyber-Attacks on Large-Scale Power Systems
Providing situational awareness in light of severe coordinated cyber-attacks on power grids, where many measurements may be untrusted, is necessary for reliable monitoring and resilient operation of the grid. In this scenario, the set of good measurements is by itself insufficient for state estimation due to loss of observability. In this paper, we present a resilient state estimation algorithm, based on output clustering. By augmenting the measurement set by respective cluster variables, the system observability is regained, and a reliable state estimate can be computed. We show the numerical performance of our proposed algorithm and its ability to successfully replace corrupted measurements using cluster variables through an example on the IEEE 24-bus power system.Department of Energy (Award DE-OE0000779
Childrenâs understanding of emotion causes: Question of future
Question of development of childrenâs understanding of emotions causes has attracted a significant research attention. Childâs understanding of present wishes and beliefs, as well as understanding of past events as being the cause of emotions, has been researched. Research reported in this paper expands upon the issues of childâs understanding of emotions in relation to the future. It starts with the question of determining the age at which a child begins to understand that emotions might be caused by mental states related to the future - through imagining or expecting the future events. Three basic emotions (fear, happiness, and sadness) has been selected and for each of them two simple stories have been created: one for immediate and other for the more distant future. Stories were illustrated and given to the group of 24 participants (12 boys and 12 girls) ages of 5, 8 and 11 (total N = 72). Overall findings are in accord with previous research in the fild. Itâs been determined that even preschool children can understand mental states related to the future. Such mental states more often occur as explanation of fear than of happiness or sadness, while the transitional age from situational to mental states explanations is between ages of five to eight
Is a Legally Binding Ban on Internet Sales of Tobacco Products Compatible with WTO Obligations? Legal Opinion Submitted to the Secretariat of the World Health Organization WHO, February 23, 2009
Linker Regions of the RhaS and RhaR Proteins
Substitutions within the interdomain linkers of the AraC/XylS family proteins RhaS and RhaR were tested to determine whether side chain identity or linker structure was required for function. Neither was found crucial, suggesting that the linkers do not play a direct role in activation, but rather simply connect the two domains
DNA binding, antibacterial and antifungal activities of copper(II) complexes with some S-alkenyl derivatives of thiosalicylic acid
The biological activities of two binuclear copper(II) complexes containing S-alkenyl derivatives of thiosalicylic acid are reported [alkenyl = propenyl (L1), isobutenyl (L2)]. The structure of the complex with the S-isobutenyl derivative (C2) was confirmed by single-crystal X-ray structure analysis, which revealed that the structure consists of centrosymmetric, dinuclear complex molecules [Cu-2(S-i-butenyl-thiosal)(4)(DMSO)(2)] containing two Cu(II) centers bridged by four S-isobutyl-thiosalicylate ligands in a paddle-wheel type structure. The Cu(II) atom is situated in a distorted square-pyramidal environment formed by carboxylate oxygen atoms in the basal plane and a DMSO ligand in the axial position. The reactivities of the complexes toward guanosine-5-monophosphate (5-GMP) were investigated. Complex C2 ([Cu-2(S-i-butenyl-thiosal)(4)(H2O)(2)]) reacted more rapidly with 5-GMP than complex C1. The interactions of complexes C1 and C2 with calf thymus DNA (CT-DNA) were examined by absorption (UV-Vis) and emission spectral studies (ethidium bromide displacement studies), revealing good DNA interaction abilities. The antimicrobial activities of the free ligands and their complexes were tested by microdilution method, and both minimal inhibitory and microbicidal concentrations were determined. All the tested substances demonstrated selective and moderate antibacterial activity on gram-positive bacteria, but low antibacterial activity on gram-negative bacteria. Also, the tested substances demonstrated low antifungal activity
