This paper studies the tensions between egalitiarian sentiments, equity concerns, self-interest, and the need for incentives in a society. We propose an experimental game in which subjects can assign their endowment to private or (more efficient) group production activities, with the proceeds from group activity divided either equally, in proportion to contribution, or by combination of the two...

or Hets and WT (Table 1) for testicular weights, a measure of total sperm production. However, in analyses of a minimum of 200 sperm per animal, gross motility (80% reduced) and progressive motility (91% reduced) were significantly (P < 0.001; Table 1) impaired in null sperm, compared to WT. The Het sperm showed 35% and 32% decrease (P < 0.001) in gross and progressive motility (P < 0.001), com...

Cellular ribosomal protein L29 (RPL29) is known to be important in protein synthesis, but its function during angiogenesis has never been described before. We have shown previously that mice lacking β3-integrins support enhanced tumour angiogenesis and, therefore, deletion of endothelial αvβ3 can provide a method for discovery of novel regulators of tumour angiogenesis. Here, we describe signif...

Abstract We use the spectral lag catalog of 46 short GRBs aggregated by Xiao et al. (Astrophys J Lett 924:L29, 2022), to carry out an independent search for Lorentz invariance violation (LIV). For this purpose, we a power-law model as function energy intrinsic astrophysical induced lags. The expansion history universe needed constraining LIV was obtained in non-parametric method using cosmic ch...
