Article Synopsis
- Researchers studied blood markers to see if they could predict recovery in people with severe brain injuries who had been in a coma for a long time.
- They looked at 25 patients and measured these markers at three different times: when they got hurt, when they entered rehab, and when they left.
- The study found that certain markers decreased in blood levels when patients improved, suggesting that those markers could help predict recovery in the future.
The associated production of a Higgs boson with a top-antitop quark pair is a crucial process at the LHC since it allows for a direct measurement of the top-quark Yukawa coupling. We present the computation of the radiative corrections to this process at the next-to-next-to-leading order (NNLO) in QCD perturbation theory. This is the very first computation for a 2→3 process with massive colored particles at this perturbative order.

We discuss the resummation formalism for the production of the system at small values of its total transverse momentum . We present the results of the corresponding resummation coefficients at next-to-leading and, partly, next-to-next-to-leading order.

We present two proposals of a soft-gluon effective coupling that extend the CMW coupling to all perturbative orders in the coupling . Although both effective couplings are well-defined in the physical four-dimensional space time, we examine their behaviour in space time dimensions.

Methods: Thirty-four patients were included in this study and randomly allocated either to treatment with multidisciplinary rehabilitation plus cognitive training or to treatment with multidisciplinary rehabilitation alone.
Results: After 3 months of cognitive treatment, the patients assigned to the rehabilitation plus cognitive training group displayed an improvement in the cognitive test of executive function and a marked improvement in quality of life (QoL).
