The neutrophil as firefighter
entrosomes are required for cytokinesis and are important in cell cycle progression—but how are centrosomes connected to these essential cellular functions at the molecular level? On page 535, Gromley et al. describe the maternal cen-triole protein centriolin, the first integral centrosome protein linked to both cytokinesis and cell cycle progression in vertebrate cells. Overexpression, siRNA s...
متن کاملThe firefighter problem with more than one firefighter on trees
In this paper we study the complexity of the firefighter problem and related problems on trees when more than one firefighter is available at each time step, and answer several open questions of [8]. More precisely, when b ≥ 2 firefighters are allowed at each time step, the problem is NP-complete for trees of maximum degree b+2 and polynomial-time solvable for trees of maximum degree b + 2 when...
متن کاملThe Stochastic Firefighter Problem
The dynamics of infectious diseases spread is crucial in determining their risk and offering ways to contain them. We study sequential vaccination of individuals in networks. In the original (deterministic) version of the Firefighter problem, a fire breaks out at some node of a given graph. At each time step, b nodes can be protected by a firefighter and then the fire spreads to all unprotected...
متن کاملCotton as an Innovative Fabric for Firefighter Protective Clothing
Firefighting is a dangerous occupation that relies heavily on the effectiveness of protective clothing. This type of protective clothing must resist heat, flame, rough surfaces, and sharp objects as well as protect the wearer against biological/chemical surfaces. In order to address these issues, a survey was administered to firefighters to determine necessary changes that would make the presen...
