Automatic filters for the detection of coherent structure in spatiotemporal systems.
TLDR
Two approaches to automatically filter the changing configurations of spatial dynamical systems and extract coherent structures are presented, a modification of the local Lyapunov exponent approach suitable to cellular automata and other discrete spatial systems and a more traditional approach based on an order parameter and free energy is compared.

Stimulus-Induced Changes in Blood Flow and 2-Deoxyglucose Uptake Dissociate in Ipsilateral Somatosensory Cortex
TLDR
The vasoconstriction and the decrease in blood flow in the presence of an increase in 2DG uptake in the ipsilateral SI contradict the prominent metabolic hypothesis regarding the regulation of cerebral blood flow, which postulates that the state of neuroglial energy consumption determines the regional blood flow through the production of vasoactive metabolites.

The DLR MIRO: a versatile lightweight robot for surgical applications
TLDR
The DLR MIRO robot focuses on compact, slim and lightweight design to assist the surgeon directly at the operating table without interference, and integrates torque‐sensing capabilities to enable close interaction with human beings.

Quantifying self-organization with optimal predictors.
TLDR
This Letter proposes a new criterion, namely, an internally generated increase in the statistical complexity, the amount of information required for optimal prediction of the system's dynamics, for spatially extended dynamical systems.

Thalamic activity that drives visual cortical plasticity
TLDR
These findings substantially alter the interpretation of previous studies and define the afferent activity patterns that trigger cortical plasticity.

Analysis of LFP phase predicts sensory response of barrel cortex.
TLDR
The results suggest that, in the presence of ongoing oscillations, there can be a continuum of response properties and that each phase may, at times, need to be considered a distinct cortical state.

The DLR hand arm system
TLDR
An anthropomorphic hand arm system using variable stiffness actuation has been developed at DLR and a paradigm change from impedance controlled, but mechanically stiff joints to robots using intrinsic variable compliance joints is carried out.

Rapid Structural Remodeling of Thalamocortical Synapses Parallels Experience-Dependent Functional Plasticity in Mouse Primary Visual Cortex
TLDR
The hypothesis that the rapid plasticity of TC synapses is a key step in the sequence of events that shift OD in visual cortex is supported.

MICA - A new generation of versatile instruments in robotic surgery
TLDR
The capabilities of a robotic system need to be expandable as new tasks arise to protect the initial investment and to meet demands for lower cost of care.

Discrete Time Rescaling Theorem: Determining Goodness of Fit for Discrete Time Statistical Models of Neural Spiking
TLDR
It is demonstrated that finite temporal resolution of discrete time models prevents their rescaled ISIs from being exponentially distributed, and a discrete time version of the time-rescaling theorem is proved that analytically corrects for the effects of finite resolution.
