An Old Mechanism, Imitation, Geared for Socio-Material Knowing in a “Day in the Life” of First Graders

open access: yesFrontiers in Psychology, 2020
This paper adopts sociomateriality as a theoretical lens to further our understanding of how imitation acts to support the use of objects, and in doing so, constitutes a sociomaterial practice.

Automated FRAP microscopy for high‐throughput analysis of protein dynamics in chromatin organization and transcription

open access: yesFEBS Open Bio, EarlyView.
RoboMic is an automated confocal microscopy pipeline for high‐throughput functional imaging in living cells. Demonstrated with fluorescence recovery after photobleaching (FRAP), it integrates AI‐driven nuclear segmentation, ROI selection, bleaching, and analysis.

Hand to mouth: automatic imitation across effector systems

open access: yes, 2007
The effector-specificity of automatic imitation was investigated using a stimulus-response compatibility (SRC) procedure in which participants were required to make an open or a close response with either their hand or their mouth.

Spontaneous emergence, imitation and spread of alternative foraging techniques among groups of vervet monkeys

open access: yes, 2012
Animal social learning has become a subject of broad interest, but demonstrations of bodily imitation in animals remain rare. Based on Voelkl and Huber's study of imitation by marmosets, we tested four groups of semi-captive vervet monkeys presented with

Adaptive Point-Based Value Iteration for Continuous States POMDP in Goal-Directed Imitation Learning [PDF]

open access: yes, 2012
In motion planning and robot navigation, continuous domain would be the natural way of representation of state space. However, discretization is needed in order to deal with continuous state space.

Cellular imitations

open access: yesCurrent Opinion in Chemical Biology, 2012
Synthetic biologists typically construct new pathways within existing cells. While useful, this approach in many ways ignores the undefined but necessary components of life. A growing number of laboratories have begun to try to remove some of the mysteries of cellular life by building life-like systems from non-living component parts.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Phonetic Imitation of Vowel Duration in L2 Speech [PDF]

open access: yes, 2013
This paper reports the results of a pilot study concerned with phonetic imitation in the speech of Polish learners of English. The purpose of the study was to investigate whether native speakers of Polish imitate the length of English vowels and to ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Competition, Imitation and Growth with Non-Diversifiable Risk [PDF]

open access: yes
This paper analyzes the growth and welfare effects of competition in an endogenously-growing economy with imitation and non-diversifiable risk. The main findings are as follows. There is no imitation without positive profits during innovation races.
