C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Taking it in turn: an experimental test of theories of the household [PDF]

open access: yes
Using a sample of established couples, we conduct an experiment on household decision-making. Individual partners first make a series of dichotomous choices between household goods and vouchers for experiences and then the couple jointly face the same ...

Pragmatic functions of lengthenings and filled pauses in the adult-directed speech of Hungarian children [PDF]

open access: yes, 2013
Two most common disfluencies of spontaneous speech, vowel lengthenings (VLE) and non-lexicalized filled pauses (NLFP) were investigated in the adult-directed speech of eight Hungarian children.

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

open access: yesFEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

The evolution of cooperative turn-taking in animal conflict

open access: yesBMC Evolutionary Biology, 2011
Background A fundamental assumption in animal socio-ecology is that animals compete over limited resources. This view has been challenged by the finding that individuals might cooperatively partition resources by "taking turns".

Learning, Teaching, and Turn Taking in the Repeated Assignment Game [PDF]

open access: yes
History-dependent strategies are often used to support cooperation in repeated game models. Using the indefinitely repeated common-pool resource assignment game and a perfect stranger experimental design, this paper reports novel evidence that players ...

A Generative Model of Group Conversation

open access: yes, 2017
Conversations with non-player characters (NPCs) in games are typically confined to dialogue between a human player and a virtual agent, where the conversation is initiated and controlled by the player.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
