    doi: 10.1038/332691a0

    Publisher: Springer Science and Business Media LLC

    The chemical composition of the solid grains from comet Halley can be inferred from impact-ionization time-of-flight mass spectrometry. Halley's dust in the vicinity of the VEGA-1 spacecraft is a mixture of a refractory organic component and unequilibrated silicates, bu...

  • It is well documented that ancient sickle harvesting led to tough rachises, but the other seed dispersal properties in crop progenitors are rarely discussed. The first steps toward domestication are evolutionary responses for the recruitment of humans as dispersers. See...

    doi: 10.1016/s0196-6774(03)00046-4

    Publisher: Elsevier BV

    We study the average-case running-time of single-source shortest-path (SSSP) algorithms assuming arbitrary directed graphs with n nodes, m edges, and independent random edge weights uniformly distributed in [0,1]. We give the first label-setting and label-correcting alg...

    Abstract Anti-CD19 chimeric antigen receptor (CAR) T cells showed significant antileukemic activity in B-precursor acute lymphoblastic leukemia (ALL). Allogeneic, HLA-mismatched off-the-shelf third-party donors may offer ideal fitness of the effector cells, but carry th...

    Attempts to influence the development of land systems are often based on detailed scenarios that constrain relevant factors, describe a range of divergent but plausible futures and identify potential pathways to visions of desirable conditions. However, a number of assu...

    Publisher: Royal Society of Chemistry (RSC)

    Rapid and specific rare cell detection for point-of-care testing requires an integration of the sample preparation for flow cytometry. To achieve such a challenging goal we have developed a magnetic flow cytometry technique which applies magnetophoresis to perform cell ...

    doi: 10.1002/job.2005

    Publisher: Wiley

    Summary This paper examines the role of affect as a linking mechanism between experiences at work (perceived prosocial impact and situational constraints) and two distinct components of proactive work behavior (issue identification and implementation). Based on a dual-t...
