    [[abstract]]The purpose of this research is to evaluate the performance of the National Science and Technology Program (NSTP) by targeting the Taiwan National Telecommunication Program (NIP) initiated in 1998. The Taiwan telecommunications industry has prospered, currently occupying key positions in global markets even though NTP seldom contributes positively to patent citation performance. Hence, the authors of this study investigate the qualitative perspective of intellectual capital rather than quantitative technological indices. The current study focuses on both human capital and relational assets through surveys of 53 principal investigators of NTP projects and 63 industrial R&D managers of telecommunications corporations in the Taiwan market. Results show that NSTP member quality and the flow of employment are good indicators of human capital and that both perform better than the middle value in the case of Taiwan NTP. In addition, we find that industrial participants are more likely to share R&D resources than other academic researchers with higher intention of co-publishing, co-funding, and sharing equipments and facilities. The industrial NTP participants also have higher expectations regarding achieving advanced technology breakthroughs in contrast to non-NIP industrial interviewees. Moreover, industrial participants with greater industry-university cooperation intensity indeed obtain a particular advantage, that is, greater knowledge acquisition from other fields related to the effect of knowledge spillovers through the particular NSTP linkage. Accordingly, from the perspectives of human capital and relational assets, the authors conclude by articulating the importance of absorptive capacity resulting from good human capital and knowledge spillover contributed by relational assets within governmental technology policy and NSTP programming.

    Gluon fusion and bb¯ corrections to HW+W−/HZZ production in the POWHEG-BOX

    AbstractThe study of the Higgs boson properties is one of the most important tasks to be accomplished in the next years, at the Large Hadron Collider (LHC) and at future colliders such as the Future Circular Collider in hadron–hadron mode (FCC-hh), the potential 100 TeV follow-up of the LHC machine. In this view the precise study of the Higgs couplings to weak gauge bosons is crucial and requires as much information as possible. After the recent calculation of the next-to-leading order QCD corrections to the production cross sections and differential distributions of a Standard Model Higgs boson in association with a pair of weak bosons, matched with parton shower in the POWHEG-BOX framework, we present the gluon fusion correction gg→HW+W−(HZZ) to the process pp→HW+W−(HZZ). This correction can be sizeable and amounts to +3% (+10%) in the HW+W− process and +5% (+18%) in the HZZ process at the LHC (FCC-hh). We also present the first study of the impact of the bottom-quark initiated channels bb¯→HW+W−/HZZ and find that they induce a significant +18% correction in the HW+W− channel at the FCC-hh. We present results on total cross sections and distributions at the LHC and at the FCC-hh

    Nanodiamond-based two-step sampling of multiply and singly phosphorylated peptides for MALDI-TOF mass spectrometry analysis

    No full text
    [[abstract]]Simultaneous detection of multiply and singly phosphorylated peptides using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is challenging because of suppression effects during ionization. In oder to overcome this problem, this study presents a new approach to improve the detection of phosphopeptides by stepwise enrichment using polyarginine-coated (PA-coated) and titanium dioxide-coated (TiO(2)-coated) nanodiamonds for fractionation of multiply and singly phosphorylated peptides prior to on-probe MALDI MS analysis. The feasibility of this approach was demonstrated using synthetic peptides containing different numbers of phosphate groups, tryptic digests of alpha-casein, beta-casein, and complex protein mixtures. The high specificity of the approach is shown in its effective enrichment and fractionation of phosphopeptides from the digest of beta-casein and bovine serum albumin at a molar ratio as low as 1 : 1000, which out-performs the commercial Fe(3+)-IMAC and TiO(2) isolation kits. It offers a simple and effective alternative for the fractionation and identification of multiply and singly phosphorylated peptides by MALDI MS and allows for deduction of more information from limited starting materials.[[note]]SC
