The dif/Xer Recombination Systems in Proteobacteria [PDF]
PLoS ONE, 2009 In E. coli, 10 to 15% of growing bacteria produce dimeric chromosomes during DNA replication. These dimers are resolved by XerC and XerD, two tyrosine recombinases that target the 28-nucleotide motif (dif) associated with the chromosome's replication terminus.

Dif-in-Dif Estimators of Multiplicative Treatment Effects [PDF]
Journal of Econometric Methods, 2014 Abstract We consider a difference-in-differences setting with a continuous outcome. The standard practice is to take its logarithm and then interpret the results as an approximation of the multiplicative treatment effect on the original outcome.

Prompt fission neutron spectra in the 235U(n,f) reaction [PDF]
EPJ Web of Conferences, 2023 Prompt fission neutron spectra (PFNS) are crucial to any neutronic simulation of critical nuclear systems. An experimental setup dedicated to the measurements of PFNS of very high accuracy was developed at the Los Alamos Neutron Science Center (LANSCE ...

Anchor selection strategies for DIF analysis: Review, assessment, and new approaches [PDF]
, 2013 Differential item functioning (DIF) indicates the violation of the invariance assumption for instance in models based on item response theory (IRT). For item-wise DIF analysis using IRT, a common metric for the item parameters of the groups that are to ...

Anchor methods for DIF detection: A comparison of the iterative forward, backward, constant and all-other anchor class [PDF]
, 2013 In the analysis of differential item functioning (DIF) using item response theory (IRT), a common metric is necessary to compare item parameters between groups of test-takers.

Models dif-in-dif en dades telemàtiques d'accidents d'automòbil [PDF]
El proyecto analiza cómo cambia el comportamiento de una persona después de haber tenido un accidente de tráfico mediante la técnica econométrica Dif-in-Dif (Difference-in-Difference). Concretamente se comparan los cambios antes y después del accidente en dos grupos: el grupo “tratamiento” (afectados por el accidente) y el grupo “control” (sin ...

Evaluation of memory-preserving models for particle transport in random media [PDF]
EPJ Web of ConferencesA shortcoming of the Levermore-Pomraning (LP) model is its inaccuracy to treat the transport of particles in a diffusive material alternating with a transparent one. Enhanced-memory LP models have been proposed by Zimermann et al.
