Mechanistic studies of initiator–initiator interaction and replication initiation [PDF]
The EMBO Journal, 1998 Unlike the chromosome of Escherichia coli that needs only one replication initiator protein (origin recognition protein) called DnaA, many plasmid replicons require dual initiators: host-encoded DnaA and a plasmid-encoded origin recognition protein, which is believed to be the major determinant of replication control. Hitherto, the relative mechanistic

The Secrets of Meristems Initiation: Axillary Meristem Initiation and Floral Meristem Initiation
Plants, 2023 The branching phenotype is an extremely important agronomic trait of plants, especially for horticultural crops. It is not only an important yield character of fruit trees, but also an exquisite ornamental trait of landscape trees and flowers. The branching characteristics of plants are determined by the periodic initiation and later development of ...

Improved Initialization Method for Metaheuristic Algorithms: A Novel Search Space View
IEEE Access, 2021 As an essential step of metaheuristic optimizers, initialization seriously affects the convergence speed and solution accuracy. The main motivation of the state-of-the-art initialization method is to generate a small initial population to cover the ...

Tellus: Series A, Dynamic Meteorology and Oceanography, 2021 Limitations to operational weather forecasts exist in terms of availability of computer (and human) resources combined with operational deadlines. For operational weather services it is therefore important to utilize their resources to maximize the ...

Criticism of the Translation of the Marked Informational Structure in Najib Mahfouz's Novels (Case study: the novels "Al-Shahaz" and "Al-Tariq") [PDF]
پژوهشهای ترجمه در زبان و ادبیات عربی, 2022 Deviation from the usual lexical arrangement in any language creates constructions called marked informational constructions. Marked constructions have pragmatic meanings and a communicative role in the discourse, and since translation is a communicative

Initial Events in Bacterial Transcription Initiation [PDF]
Biomolecules, 2015 Transcription initiation is a highly regulated step of gene expression. Here, we discuss the series of large conformational changes set in motion by initial specific binding of bacterial RNA polymerase (RNAP) to promoter DNA and their relevance for regulation. Bending and wrapping of the upstream duplex facilitates bending of the downstream duplex into

Teachers’ perceptions of their own initiative: Collective initiative vs. personal initiative [PDF]
Zbornik Instituta za pedagoska istrazivanja, 2013 Current trends in education demand from teachers to exhibit proactive behaviour and assume responsibility for the implementation of changes in school practice. In that sense, it is important to study how teachers perceive their own initiative and to gain insight into the activities where such initiative is demonstrated.
