The first global QCD analysis of the quark transversity distributions in the nucleon has been performed, using a new Monte Carlo method based on nested sampling and constraints on the isovector tensor charge gT from lattice QCD. A simultaneous fit to the semi-inclusive Collins asymmetry data is compatible with gT values extracted from a comprehensive reanalysis of existing lattice simulations, in contrast to previous analyses which found significantly smaller gT values. The contributions to the nucleon tensor charge from u and d quarks are found to be Δu = 0.3(2) and Δd = -0.7(2) at a scale Q2 = 2 GeV2 .

Extending the Life of Lithium-Ion Cell Phone Batteries
The results suggest mitigation of intragranular cracking requires a stable structural framework of the cathode material and carefully controlled cycling conditions. For high-voltage applications, the material’s chemistry and structure must be adjusted to minimize internal grain strain during charge and discharge cycling. In the end, these findings could generate new strategies to design stable, safe lithium-ion batteries with high energy density and a long cycle life.
