Envy-free cake divisions cannot be found by finite protocols
We show that no finite protocol (even if unbounded) can guarantee an envy-free division of a cake among three or more players, if each player is to receive a single connected piece.
متن کاملHDD cannot be advocated for all patients.
Sir, Saner and colleagues have made a good case for home haemodialysis (HHD) as an effective renal replacement therapy in Switzerland [1]. Yet, in the last paragraph of their case–cohort study of 58 patients, they admit that patient selection may have influenced their results. We agree. Our analysis of a much larger cohort, that of the United States Renal Data System, used the standardized mort...
متن کاملThe Mapping Class Group Cannot Be Realized by Homeomorphisms
Let M be a closed surface. By Homeo(M) we denote the group of orientation preserving homeomorphisms of M and let MC(M) denote the Mapping class group. In this paper we complete the proof of the conjecture of Thurston that says that for any closed surface M of genus g ≥ 2, there is no homomorphic section E : MC(M) → Homeo(M) of the standard projection map P : Homeo(M) → MC(M).
متن کاملY-str as Proof of Rape When Sperm Cells Cannot Be Found
Identification of spermatozoa is the biological evidence most often sought in the examination of rape victims. Absence of spermatozoa usually terminates biological investigations, and the victim’s testimony can therefore be contested. We assessed the utility and reliability of PCR amplification using Ychromosomal STR polymorphisms in specimens taken from female victims of sexual assault with ne...
متن کاملWhy Machines Cannot be
Mental processes are abstracted from a subset of the physical universe ; these, in turn, lead to the world of ideas. Although these ideas include quantum logic, no credible way has yet been found that constructs machines which use superimposed possibilities in the style of quantum logic, more general in computing power to machines based on classical logic. Machine theories are based exclusively...
