text: Three-dimensional (3D) reconstruction of living brain tissue down to an individual
synapse level would create opportunities for decoding the dynamics and structure–function
relationships of the brain’s complex and dense information processing network;
however, this has been hindered by insufficient 3D resolution, inadequate signal-to-noise
ratio and prohibitive light burden in optical imaging, whereas electron microscopy
is inherently static. Here we solved these challenges by developing an integrated
optical/machine-learning technology, LIONESS (live information-optimized nanoscopy
enabling saturated segmentation). This leverages optical modifications to stimulated
emission depletion microscopy in comprehensively, extracellularly labeled tissue
and previous information on sample structure via machine learning to simultaneously
achieve isotropic super-resolution, high signal-to-noise ratio and compatibility
with living tissue. This allows dense deep-learning-based instance segmentation
and 3D reconstruction at a synapse level, incorporating molecular, activity and
morphodynamic information. LIONESS opens up avenues for studying the dynamic functional
(nano-)architecture of living brain tissue.

text: Complex wiring between neurons underlies the information-processing network
enabling all brain functions, including cognition and memory. For understanding
how the network is structured, processes information, and changes over time, comprehensive
visualization of the architecture of living brain tissue with its cellular and
molecular components would open up major opportunities. However, electron microscopy
(EM) provides nanometre-scale resolution required for full in-silico
reconstruction1–5, yet is limited to fixed specimens and
static representations. Light microscopy allows live observation, with super-resolution
approaches6–12 facilitating nanoscale visualization, but
comprehensive 3D-reconstruction of living brain tissue has been hindered by tissue
photo-burden, photobleaching, insufficient 3D-resolution, and inadequate signal-to-noise
ratio (SNR). Here we demonstrate saturated reconstruction of living brain tissue.
We developed an integrated imaging and analysis technology, adapting stimulated
emission depletion (STED) microscopy6,13 in extracellularly
labelled tissue14 for high SNR and near-isotropic resolution.
Centrally, a two-stage deep-learning approach leveraged previously obtained information
on sample structure to drastically reduce photo-burden and enable automated volumetric
reconstruction down to single synapse level. Live reconstruction provides unbiased
analysis of tissue architecture across time in relation to functional activity
and targeted activation, and contextual understanding of molecular labelling.
This adoptable technology will facilitate novel insights into the dynamic functional
architecture of living brain tissue.

text: In the context of robotic manipulation and grasping, the shift from a view
that is static (force closure of a single posture) and contact-deprived (only
contact for force closure is allowed, everything else is obstacle) towards a view
that is dynamic and contact-rich (soft manipulation) has led to an increased interest
in soft hands. These hands can easily exploit environmental constraints and object
surfaces without risk, and safely interact with humans, but present also some
challenges. Designing them is difficult, as well as predicting, modelling, and
“programming” their interactions with the objects and the environment. This paper
tackles the problem of simulating them in a fast and effective way, leveraging
on novel and existing simulation technologies. We present a triple-layered simulation
framework where dynamic properties such as stiffness are determined from slow
but accurate FEM simulation data once, and then condensed into a lumped parameter
model that can be used to fast simulate soft fingers and soft hands. We apply
our approach to the simulation of soft pneumatic fingers.

text: We present a computational method for designing wire sculptures consisting
of interlocking wires. Our method allows the computation of aesthetically pleasing
structures that are structurally stable, efficiently fabricatable with a 2D wire
bending machine, and assemblable without the need of additional connectors. Starting
from a set of planar contours provided by the user, our method automatically tests
for the feasibility of a design, determines a discrete ordering of wires at intersection
points, and optimizes for the rest shape of the individual wires to maximize structural
stability under frictional contact. In addition to their application to art, wire
sculptures present an extremely efficient and fast alternative for low-fidelity
rapid prototyping because manufacturing time and required material linearly scales
with the physical size of objects. We demonstrate the effectiveness of our approach
on a varied set of examples, all of which we fabricated.

text: In this paper, we present a method to model hyperelasticity that is well suited
for representing the nonlinearity of real-world objects, as well as for estimating
it from deformation examples. Previous approaches suffer several limitations,
such as lack of integrability of elastic forces, failure to enforce energy convexity,
lack of robustness of parameter estimation, or difficulty to model cross-modal
effects. Our method avoids these problems by relying on a general energy-based
definition of elastic properties. The accuracy of the resulting elastic model
is maximized by defining an additive model of separable energy terms, which allow
progressive parameter estimation. In addition, our method supports efficient modeling
of extreme nonlinearities thanks to energy-limiting constraints. We combine our
energy-based model with an optimization method to estimate model parameters from
force-deformation examples, and we show successful modeling of diverse deformable
objects, including cloth, human finger skin, and internal human anatomy in a medical
imaging application.
