R Factors from Serratia Marcescens [PDF]
Journal of General Microbiology, 1975 In recent years, Serratia marcescens has become established in certain localities as an agent of hospital infection and cross-infection (Clayton & von Graevenitz, 1966; Wilfert, Barrett & Kass, 1968; Davis, Foltz & Blakemore, 1970; Wilkowske, Washington, Martin & Ritts, 1970). In general, strains of S.

Near-Optimal UGC-hardness of Approximating Max k-CSP_R [PDF]
, 2015 In this paper, we prove an almost-optimal hardness for Max $k$-CSP$_R$ based on Khot's Unique Games Conjecture (UGC). In Max $k$-CSP$_R$, we are given a set of predicates each of which depends on exactly $k$ variables.

R Factors from Proteus morganii [PDF]
Journal of General Microbiology, 1973 Summary: Twenty-eight R factors transmissible to Escherichia coli K12 were derived from 178 naturally occurring strains of Proteus morganii and evidence was found of non-transmissible resistance plasmids in some strains. Nine plasmids were assigned to group N; one P. morganii strain carried two N plasmids which were incompatible in reference strains of

Order p^6 chiral couplings from the scalar K Pi form factor [PDF]
, 2004 Employing results from a recent determination of the scalar KPi form factor F_0^KPi within a coupled channel dispersion relation analysis \cite{JOP01}, in this work we calculate the slope and curvature of F_0^KPi(t) at zero momentum transfer.

Unstable Mutants of R Factor [PDF]
Japanese Journal of Microbiology, 1969 ABSTRACTThirty mutants sensitive to tetracycline were obtained from an R100 factor capable of conferring resistance to tetracycline (TC), chloramphenicol (CM), streptomycin (SM) and sulfanilamide (SA). Among the TC sensitive mutants, three showed a high frequency of spontaneous loss from host strains.

R Factors from Proteus rettgeri [PDF]
Journal of General Microbiology, 1972 SUMMARY: Of 12 R factors transferred from wild strains of Proteus rettgeri to Escherichia coli K12, all were fi - Five were of the N-compatibility group; three belonged to a newly defined group T, of which Rts1 is the prototype; one belonged to group W. The other three constituted at least one compatibility group, not previously described.

Facilitation of the Transfer of R Factor by the Resident R Factor [PDF]
Journal of Bacteriology, 1970 Transfer of some R factors were shown to be facilitated by resident R factors. The sex factor itself may be responsible for this phenomenon.

Regularization in $L_1$ for the Ornstein--Uhlenbeck semigroup [PDF]
, 2015 Let $\gamma_n$ be the standard Gaussian measure on $\mathbb R^n$ and let $(Q_t)$ be the Ornstein--Ulhenbeck semigroup. Eldan and Lee recently established that for every non--negative function $f$ of integral $1$ and any time $t$ the following tail ...

The Effect of Porosity on X-ray Emission Line Profiles from Hot-Star Winds [PDF]
, 2006 We investigate the degree to which the nearly symmetric form of X-ray emission lines seen in Chandra spectra of early-type supergiant stars could be explained by a possibly porous nature of their spatially structured stellar winds.

Experimental Biology and Medicine, 1947 SummaryThe growth and hemoglobin responses obtained in chicks receiving a purified diet supplemented with factor R were found not to be due to the preformed folic acid present in factor R.By means of chick liver, rat liver, and hog kidney incubation procedures the folic acid content of factor R was greatly increased.
