Static Monopoles and Their Anti-Configurations

open access: yes, 2004
Recently, we have reported on the existence of some monopoles, multimonopole, and antimonopoles configurations. In this paper we would like to present more monopoles, multimonopole, and antimonopoles configurations of the magnetic ansatz of Ref.\cite{kn ...

Effects of nidopallium caudolaterale inactivation on serial-order behavior in pigeons ( Columba livia).

open access: yesJournal of Neurophysiology, 2018
Serial-order behavior is the ability to complete a sequence of responses in a predetermined order to achieve a reward. In birds, serial-order behavior is thought to be impaired by damage to the nidopallium caudolaterale (NCL).

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Generating mathematical strategies shows evidence of a serial order effect

open access: yesFrontiers in Education
This study investigated whether performance on a mathematical strategy-generating task showed evidence for a serial order effect (decreasing fluency but increasing originality and creativity of strategies over time).

Love. Break up. Repeat: The prevalence and stability of serial cohabitation among West German women and men born in the early 1970s

open access: yesDemographic Research, 2018
Background: Serial cohabitation is of growing scientific relevance as more and more people experience the formation and dissolution of multiple unmarried cohabitations.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Neural Dynamics of Learning and Performance of Fixed Sequences: Latency Pattern Reorganizations and the N-STREAMS Model [PDF]

open access: yes, 2002
Fixed sequences performed from memory play a key role in human cultural behavior, especially in music and in rapid communication through speaking, handwriting, and typing.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Does the Survival Processing Memory Advantage Translate to Serial Recall?

open access: yesCollabra: Psychology, 2020
The survival processing effect describes the phenomenon that memory for items is better after they have been processed in the context of a fitness-related survival scenario as compared to alternative processing contexts. In the present study, we examined

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
