Innovation efficiency is an important index to measure the innovation performance of high-tech enterprises.Numerous researches have been Lighters conducted on innovation efficiency at national, regional, and sectoral levels, while there are comparatively few studies on the innovation efficiency of high-tech small- and medium-sized enterprises (SMEs
The proliferation of specific lymphocytes is the central tenet of the clonal selection paradigm.Antigen recognition by T cells triggers a series of events that produces expanded clones of differentiated effector cells.TCR signaling events are detectable within seconds and minutes and are likely to continue for hours and days in vivo.Here, I review
The aim of this paper is to present the main economic developments of the most important emerging economies,brought together under the name of the BRICS, in the light of new economic and political positions which thesecountries tend to occupy in the current global context.The study is significant being a comparative presentationbetween the BRICS Gr
Pulsars, especially X-ray pulsars detectable for small-size detectors, are highly accurate natural clocks suggesting potential applications such as interplanetary navigation control.Due to various complex cosmic background noise, the original pulsar signals, namely photon sequences, observed by detectors have low signal-to-noise ratios (SNRs) that
Capacity uncertainty is a common issue in the transportation planning field.However, few studies discuss the intermodal routing problem with service capacity uncertainty.Based on our previous study on the intermodal routing under deterministic capacity consideration, we systematically explore how service capacity uncertainty influences the intermod
