The first is representation stability: a generalization of homological stability in the presence of group actions which was introduced by Church and Farb. For symmetric group actions, this is formalized in the notion of FI-modules, introduced by Church, Ellenberg, and Farb. FI-modules turn out to be modules over a twisted commutative algebra (the free tca generated by 1 element of degree 1). Th...

Data presented in the meta-analysis by Oghenowede Eyawo and colleagues sheds new light on the role of serodiscordant couples in driving the incidence of HIV in Africa. The HIV epidemic in Africa is driven by heterosexual transmission. Studies have shown transmission in stable discordant couples can be as low as 1·9 per 100 person-years to as high as 19·0 per 100 person-years; these couples are ...

The groundbreaking paper ‘Short proofs are narrow – resolution made simple’ by Ben-Sasson and Wigderson (J. ACM 2001) introduces what is today arguably the main technique to obtain resolution lower bounds: to show a lower bound for the width of proofs. Another important measure for resolution is space, and in their fundamental work, Atserias and Dalmau (J. Comput. Syst. Sci. 2008) show that low...

abstract spinal cord injury (sci) is a devastating condition producing great personal and societal costs and for which there is no effective treatment. stem cell transplantation is a promising therapeutic strategy, though much preclinical and clinical research work remains. here, we briefly describe sci epidemiology, pathophysiology, and transplantation trial in human developments, including te...
