Abstract This paper is a sequel to T-structures and twisted complexes on derived injectives by the same author with W. Lowen M. Van den Bergh. We define dg-category of unbounded dg-category, which particularly interesting in case dg-categories or projectives associated t-structure. On such we natural “injective” dually “projective” intended as direct generalization homotopy categories injective...

Gracilis free muscle transfer (GFMT) is considered the gold standard in dynamic smile reanimation patients with long-standing facial paralysis. There are multiple motor nerves head and neck that can be used to provide innervation GFMT, either alone or combination. In this article, we review literature about these donor nerve options discuss their advantages disadvantages terms of excursion, spo...

Let X be a topological abelian group and H subgroup of X. We find conditions under which local quasi-convexity both X/H results in the same property for This is true instance if precompact, or metrizable dually embedded also either discrete bounded torsion. give some general principles point out errors we have found existing literature on this problem.
