The RNA Polymerase II Core Promoter in Drosophila. [PDF]

open access: yes, 2019
Transcription by RNA polymerase II initiates at the core promoter, which is sometimes referred to as the "gateway to transcription." Here, we describe the properties of the RNA polymerase II core promoter in Drosophila The core promoter is at a strategic

k-core (bootstrap) percolation on complex networks: Critical phenomena and nonlocal effects

open access: yes, 2006
We develop the theory of the k-core (bootstrap) percolation on uncorrelated random networks with arbitrary degree distributions. We show that the k-core percolation is an unusual, hybrid phase transition with a jump emergence of the k-core as at a first ...

Psychoanalytic core competence [PDF]

open access: yesFrontiers in Psychology, 2015
Although it has been shown that psychotherapy is highly effective, there is still a debate on how and why method specific interventions impact on the patient. We propose that psychoanalytic competence is defined by the capability to work with and understand unconscious dynamics by adhering to specific internal attitudes and maintaining certain frames ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

The Genus Scleria in Colombia The Genus Scleria in Colombia

open access: yesCaldasia, 1948
Since the publication of my revision of the American species of the genus Scleria (*), continued field work and herbarium studies have brought to light numerous new distributional records for Colombia. In particular, the explorations of Dr.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

open access: yesFEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

A Note on the Core of TU-cooperative Games with Multiple Membership Externalities

open access: yesGames, 2014
A generalization of transferable utility cooperative games from the functional forms introduced by von Neumann and Morgenstern (1944, Theory of Games and Economic Behavior) and Lucas and Thrall (1963, Naval Research Logistics Quarterly, 10, 281–298) is ...

Second Core Formation and High Speed Jets: Resistive MHD Nested Grid Simulations

open access: yes, 2006
The stellar core formation and high speed jets driven by the formed core are studied by using three-dimensional resistive MHD nested grid simulations. Starting with a Bonnor-Ebert isothermal cloud rotating in a uniform magnetic field, we calculate the ...
