Reply to Walker et al.
TO THE EDITOR—We thank Walker et al for their interest in our work [1]. Our study found no evidence of difference in clinical severity of Clostridium difficile infection (CDI) between patients infected with ribotype 027/078 strains compared with others, when adjusted for other co-variates [2]. Adjustment for factors on the hypothesized causal pathway between exposure (ribotype) and outcome (sev...
متن کاملWalker groups
A reformulation of Walker’s theorem on the cancellation of Z says that any two homomorphisms from an abelian group B onto Z have isomorphic kernels. It does not have a constructive proof, even for B a subgroup of Z3. In this paper we give a constructive proof of Walker’s theorem for B a direct sum, over any discrete index set, of groups of the following two kinds: finite-rank torsion-free group...
متن کاملThe Transmembrane Morphogenesis Protein gp1 of Filamentous Phages Contains Walker A and Walker B Motifs Essential for Phage Assembly
In contrast to lytic phages, filamentous phages are assembled in the inner membrane and secreted across the bacterial envelope without killing the host. For assembly and extrusion of the phage across the host cell wall, filamentous phages code for membrane-embedded morphogenesis proteins. In the outer membrane of Escherichia coli, the protein gp4 forms a pore-like structure, while gp1 and gp11 ...
متن کاملA chimeric point-light walker
Ambiguity has long been used as a probe into visual processing. Here, we describe a new dynamic ambiguous figureöthe chimeric point-light walkeröwhich we hope will prove to be a useful tool for exploring biological motion. We begin by describing the construction of the stimulus and discussing the compelling finding that, when presented in a mask, observers consistently fail to notice anything o...
متن کاملReply to Walker and Stickgold: Proposed boundary conditions on memory reconsolidation will require empirical verification.
Broadly speaking, nonreplications of the kind we reported (1) can occur for three reasons: (i) the original finding was a false-positive, (ii) the replication was a false-negative, or (iii) some unanticipated variablemoderated the effect. The authors of the original study, Walker and Stickgold (2), now propose several potential moderators (3). We welcome such discussion; however, we should note...
