text: Embroidery is a long-standing and high-quality approach to making logos and
images on textiles. Nowadays, it can also be performed via automated machines
that weave threads with high spatial accuracy. A characteristic feature of the
appearance of the threads is a high degree of anisotropy. The anisotropic behavior
is caused by depositing thin but long strings of thread. As a result, the stitched
patterns convey both color and direction. Artists leverage this anisotropic behavior
to enhance pure color images with textures, illusions of motion, or depth cues.
However, designing colorful embroidery patterns with prescribed directionality
is a challenging task, one usually requiring an expert designer. In this work,
we propose an interactive algorithm that generates machine-fabricable embroidery
patterns from multi-chromatic images equipped with user-specified directionality
fields.We cast the problem of finding a stitching pattern into vector theory.
To find a suitable stitching pattern, we extract sources and sinks from the divergence
field of the vector field extracted from the input and use them to trace streamlines.
We further optimize the streamlines to guarantee a smooth and connected stitching
pattern. The generated patterns approximate the color distribution constrained
by the directionality field. To allow for further artistic control, the trade-off
between color match and directionality match can be interactively explored via
an intuitive slider. We showcase our approach by fabricating several embroidery
paths.

text: "3D printing based on continuous deposition of materials, such as filament-based
3D printing, has seen widespread adoption thanks to its versatility in working
with a wide range of materials. An important shortcoming of this type of technology
is its limited multi-material capabilities. While there are simple hardware designs
that enable multi-material printing in principle, the required software is heavily
underdeveloped. A typical hardware design fuses together individual materials
fed into a single chamber from multiple inlets before they are deposited. This
design, however, introduces a time delay between the intended material mixture
and its actual deposition. In this work, inspired by diverse path planning research
in robotics, we show that this mechanical challenge can be addressed via improved
printer control. We propose to formulate the search for optimal multi-material
printing policies in a reinforcement\r\nlearning setup. We put forward a simple
numerical deposition model that takes into account the non-linear material mixing
and delayed material deposition. To validate our system we focus on color fabrication,
a problem known for its strict requirements for varying material mixtures at a
high spatial frequency. We demonstrate that our learned control policy outperforms
state-of-the-art hand-crafted algorithms."

text: 'Color and gloss are fundamental aspects of surface appearance. State-of-the-art
fabrication techniques can manipulate both properties of the printed 3D objects.
However, in the context of appearance reproduction, perceptual aspects of color
and gloss are usually handled separately, even though previous perceptual studies
suggest their interaction. Our work is motivated by previous studies demonstrating
a perceived color shift due to a change in the object''s gloss, i.e., two samples
with the same color but different surface gloss appear as they have different
colors. In this paper, we conduct new experiments which support this observation
and provide insights into the magnitude and direction of the perceived color change.
We use the observations as guidance to design a new method that estimates and
corrects the color shift enabling the fabrication of objects with the same perceived
color but different surface gloss. We formulate the problem as an optimization
procedure solved using differentiable rendering. We evaluate the effectiveness
of our method in perceptual experiments with 3D objects fabricated using a multi-material
3D printer and demonstrate potential applications. '

text: Tattoos are a highly popular medium, with both artistic and medical applications.
Although the mechanical process of tattoo application has evolved historically,
the results are reliant on the artisanal skill of the artist. This can be especially
challenging for some skin tones, or in cases where artists lack experience. We
provide the first systematic overview of tattooing as a computational fabrication
technique. We built an automated tattooing rig and a recipe for the creation of
silicone sheets mimicking realistic skin tones, which allowed us to create an
accurate model predicting tattoo appearance. This enables several exciting applications
including tattoo previewing, color retargeting, novel ink spectra optimization,
color-accurate prosthetics, and more.

text: We calculate reflectivities of dynamically compressed water, water-ethanol
mixtures, and ammonia at infrared and optical wavelengths with density functional
theory and molecular dynamics simulations. The influence of the exchange-correlation
functional on the results is examined in detail. Our findings indicate that the
consistent use of the HSE hybrid functional reproduces experimental results much
better than the commonly used PBE functional. The HSE functional offers not only
a more accurate description of the electronic band gap but also shifts the onset
of molecular dissociation in the molecular dynamics simulations to significantly
higher pressures. We also highlight the importance of using accurate reference
standards in reflectivity experiments and reanalyze infrared and optical reflectivity
data from recent experiments. Thus, our combined theoretical and experimental
work explains and resolves lingering discrepancies between calculations and measurements
for the investigated molecular substances under shock compression.

text: A series of triarylamines was synthesised and screened for their suitability
as catholytes in redox flow batteries using cyclic voltammetry (CV). Tris(4-aminophenyl)amine
was found to be the strongest candidate. Solubility and initial electrochemical
performance were promising; however, polymerisation was observed during electrochemical
cycling leading to rapid capacity fade prescribed to a loss of accessible active
material and the limitation of ion transport processes within the cell. A mixed
electrolyte system of H3PO4 and HCl was found to inhibit polymerisation producing
oligomers that consumed less active material reducing rates of degradation in
the redox flow battery. Under these conditions Coulombic efficiency improved by
over 4 %, the maximum number of cycles more than quadrupled and an additional
theoretical capacity of 20 % was accessed. This paper is, to our knowledge, the
first example of triarylamines as catholytes in all-aqueous redox flow batteries
and emphasises the impact supporting electrolytes can have on electrochemical
performance.

show that there exists a continuous function f(c) such that Lc,n/n→f(c) a.s. for
c>20, thus extending a result of Frieze and the author to smaller values of
c. Thereafter, for c>20, we determine the limit of the probability that
G(n, c/n)contains cycles of every length between the length of its shortest and its longest

text: "We derive a weak-strong uniqueness principle for BV solutions to multiphase
mean curvature flow of triple line clusters in three dimensions. Our proof is
based on the explicit construction\r\nof a gradient flow calibration in the sense
of the recent work of Fischer et al. (2020) for any such\r\ncluster. This extends
the two-dimensional construction to the three-dimensional case of surfaces\r\nmeeting
along triple junctions."

text: Singlet oxygen (1O2) formation is now recognised as a key aspect of non-aqueous
oxygen redox chemistry. For identifying 1O2, chemical trapping via 9,10-dimethylanthracene
(DMA) to form the endoperoxide (DMA-O2) has become the mainstay method due to
its sensitivity, selectivity, and ease of use. While DMA has been shown to be
selective for 1O2, rather than forming DMA-O2 with a wide variety of potentially
reactive O-containing species, false positives might hypothetically be obtained
in the presence of previously overlooked species. Here, we first give unequivocal
direct spectroscopic proof by the 1O2-specific near infrared (NIR) emission at
1270 nm for the previously proposed 1O2 formation pathways, which centre around
superoxide disproportionation. We then show that peroxocarbonates, common intermediates
in metal-O2 and metal carbonate electrochemistry, do not produce false-positive
DMA-O2. Moreover, we identify a previously unreported 1O2-forming pathway through
the reaction of CO2 with superoxide. Overall, we give unequivocal proof for 1O2
formation in non-aqueous oxygen redox and show that chemical trapping with DMA
is a reliable method to assess 1O2 formation.

text: In this paper we introduce a pruning of the medial axis called the (λ,α)-medial
axis (axλα). We prove that the (λ,α)-medial axis of a set K is stable in a Gromov-Hausdorff
sense under weak assumptions. More formally we prove that if K and K′ are close
in the Hausdorff (dH) sense then the (λ,α)-medial axes of K and K′ are close as
metric spaces, that is the Gromov-Hausdorff distance (dGH) between the two is
1/4-Hölder in the sense that dGH (axλα(K),axλα(K′)) ≲ dH(K,K′)1/4. The Hausdorff
distance between the two medial axes is also bounded, by dH (axλα(K),λα(K′)) ≲
dH(K,K′)1/2. These quantified stability results provide guarantees for practical
computations of medial axes from approximations. Moreover, they provide key ingredients
for studying the computability of the medial axis in the context of computable
analysis.

text: "We propose a computational design approach for covering a surface with individually
addressable RGB LEDs, effectively forming a low-resolution surface screen. To
achieve a low-cost and scalable approach, we propose creating designs from flat
PCB panels bent in-place along the surface of a 3D printed core. Working with
standard rigid PCBs enables the use of\r\nestablished PCB manufacturing services,
allowing the fabrication of designs with several hundred LEDs. \r\nOur approach
optimizes the PCB geometry for folding, and then jointly optimizes the LED packing,
circuit and routing, solving a challenging layout problem under strict manufacturing
requirements. Unlike paper, PCBs cannot bend beyond a certain point without breaking.
Therefore, we introduce parametric cut patterns acting as hinges, designed to
allow bending while remaining compact. To tackle the joint optimization of placement,
circuit and routing, we propose a specialized algorithm that splits the global
problem into one sub-problem per triangle, which is then individually solved.\r\nOur
technique generates PCB blueprints in a completely automated way. After being
fabricated by a PCB manufacturing service, the boards are bent and glued by the
user onto the 3D printed support. We demonstrate our technique on a range of physical
models and virtual examples, creating intricate surface light patterns from hundreds
of LEDs."

text: Imaging of the immunological synapse (IS) between dendritic cells (DCs) and
T cells in suspension is hampered by suboptimal alignment of cell-cell contacts
along the vertical imaging plane. This requires optical sectioning that often
results in unsatisfactory resolution in time and space. Here, we present a workflow
where DCs and T cells are confined between a layer of glass and polydimethylsiloxane
(PDMS) that orients the cells along one, horizontal imaging plane, allowing for
fast en-face-imaging of the DC-T cell IS.

text: 'Deep neural networks (DNNs) often have to be compressed, via pruning and/or
quantization, before they can be deployed in practical settings. In this work
we propose a new compression-aware minimizer dubbed CrAM that modifies the optimization
step in a principled way, in order to produce models whose local loss behavior
is stable under compression operations such as pruning. Thus, dense models trained
via CrAM should be compressible post-training, in a single step, without significant
accuracy loss. Experimental results on standard benchmarks, such as residual networks
for ImageNet classification and BERT models for language modelling, show that
CrAM produces dense models that can be more accurate than the standard SGD/Adam-based
baselines, but which are stable under weight pruning: specifically, we can prune
models in one-shot to 70-80% sparsity with almost no accuracy loss, and to 90%
with reasonable (∼1%) accuracy loss, which is competitive with gradual compression
methods. Additionally, CrAM can produce sparse models which perform well for transfer
learning, and it also works for semi-structured 2:4 pruning patterns supported
by GPU hardware. The code for reproducing the results is available at this https

text: "Deep learning has become an integral part of a large number of important
applications, and many of the recent breakthroughs have been enabled by the ability
to train very large models, capable to capture complex patterns and relationships
from the data. At the same time, the massive sizes of modern deep learning models
have made their deployment to smaller devices more challenging; this is particularly
important, as in many applications the users rely on accurate deep learning predictions,
but they only have access to devices with limited memory and compute power. One
solution to this problem is to prune neural networks, by setting as many of their
parameters as possible to zero, to obtain accurate sparse models with lower memory
footprint. Despite the great research progress in obtaining sparse models that
preserve accuracy, while satisfying memory and computational constraints, there
are still many challenges associated with efficiently training sparse models,
as well as understanding their generalization properties.\r\n\r\nThe focus of
this thesis is to investigate how the training process of sparse models can be
made more efficient, and to understand the differences between sparse and dense
models in terms of how well they can generalize to changes in the data distribution.
We first study a method for co-training sparse and dense models, at a lower cost
compared to regular training. With our method we can obtain very accurate sparse
networks, and dense models that can recover the baseline accuracy. Furthermore,
we are able to more easily analyze the differences, at prediction level, between
the sparse-dense model pairs. Next, we investigate the generalization properties
of sparse neural networks in more detail, by studying how well different sparse
models trained on a larger task can adapt to smaller, more specialized tasks,
in a transfer learning scenario. Our analysis across multiple pruning methods
and sparsity levels reveals that sparse models provide features that can transfer
similarly to or better than the dense baseline. However, the choice of the pruning
method plays an important role, and can influence the results when the features
are fixed (linear finetuning), or when they are allowed to adapt to the new task
(full finetuning). Using sparse models with fixed masks for finetuning on new
tasks has an important practical advantage, as it enables training neural networks
on smaller devices. However, one drawback of current pruning methods is that the
entire training cycle has to be repeated to obtain the initial sparse model, for
every sparsity target; in consequence, the entire training process is costly and
also multiple models need to be stored. In the last part of the thesis we propose
a method that can train accurate dense models that are compressible in a single
step, to multiple sparsity levels, without additional finetuning. Our method results
in sparse models that can be competitive with existing pruning methods, and which
can also successfully generalize to new tasks."

text: During development, tissues undergo changes in size and shape to form functional
organs. Distinct cellular processes such as cell division and cell rearrangements
underlie tissue morphogenesis. Yet how the distinct processes are controlled and
coordinated, and how they contribute to morphogenesis is poorly understood. In
our study, we addressed these questions using the developing mouse neural tube.
This epithelial organ transforms from a flat epithelial sheet to an epithelial
tube while increasing in size and undergoing morpho-gen-mediated patterning. The
extent and mechanism of neural progenitor rearrangement within the developing
mouse neuroepithelium is unknown. To investigate this, we per-formed high resolution
lineage tracing analysis to quantify the extent of epithelial rear-rangement at
different stages of neural tube development. We quantitatively described the relationship
between apical cell size with cell cycle dependent interkinetic nuclear migra-tions
(IKNM) and performed high cellular resolution live imaging of the neuroepithelium
to study the dynamics of junctional remodeling. Furthermore, developed a vertex
model of the neuroepithelium to investigate the quantitative contribution of cell
proliferation, cell differentiation and mechanical properties to the epithelial
rearrangement dynamics and validated the model predictions through functional
experiments. Our analysis revealed that at early developmental stages, the apical
cell area kinetics driven by IKNM induce high lev-els of cell rearrangements in
a regime of high junctional tension and contractility. After E9.5, there is a
sharp decline in the extent of cell rearrangements, suggesting that the epi-thelium
transitions from a fluid-like to a solid-like state. We found that this transition
is regulated by the growth rate of the tissue, rather than by changes in cell-cell
adhesion and contractile forces. Overall, our study provides a quantitative description
of the relationship between tissue growth, cell cycle dynamics, epithelia rearrangements
and the emergent tissue material properties, and novel insights on how epithelial
cell dynamics influences tissue morphogenesis.

text: We use a function field version of the Hardy–Littlewood circle method to study
the locus of free rational curves on an arbitrary smooth projective hypersurface
of sufficiently low degree. On the one hand this allows us to bound the dimension
of the singular locus of the moduli space of rational curves on such hypersurfaces
and, on the other hand, it sheds light on Peyre’s reformulation of the Batyrev–Manin
conjecture in terms of slopes with respect to the tangent bundle.

text: There is a need for the development of lead-free thermoelectric materials
for medium-/high-temperature applications. Here, we report a thiol-free tin telluride
(SnTe) precursor that can be thermally decomposed to produce SnTe crystals with
sizes ranging from tens to several hundreds of nanometers. We further engineer
SnTe–Cu2SnTe3 nanocomposites with a homogeneous phase distribution by decomposing
the liquid SnTe precursor containing a dispersion of Cu1.5Te colloidal nanoparticles.
The presence of Cu within the SnTe and the segregated semimetallic Cu2SnTe3 phase
effectively improves the electrical conductivity of SnTe while simultaneously
reducing the lattice thermal conductivity without compromising the Seebeck coefficient.
Overall, power factors up to 3.63 mW m–1 K–2 and thermoelectric figures of merit
up to 1.04 are obtained at 823 K, which represent a 167% enhancement compared
with pristine SnTe.

using thermoelectric devices finds numerous potential uses, especially around
room temperature. However, the relatively high material processing cost limits
their real applications. Silver selenide (Ag2Se) is one of the very few n-type
thermoelectric (TE) materials for room-temperature applications. Herein, we report
a room temperature, fast, and aqueous-phase synthesis approach to produce Ag2Se,
which can be extended to other metal chalcogenides. These materials reach TE figures
of merit (zT) of up to 0.76 at 380 K. To improve these values, bismuth sulfide
(Bi2S3) particles also prepared in an aqueous solution are incorporated into the
Ag2Se matrix. In this way, a series of Ag2Se/Bi2S3 composites with Bi2S3 wt %
of 0.5, 1.0, and 1.5 are prepared by solution blending and hot-press sintering.
The presence of Bi2S3 significantly improves the Seebeck coefficient and power
factor while at the same time decreasing the thermal conductivity with no apparent
drop in electrical conductivity. Thus, a maximum zT value of 0.96 is achieved
in the composites with 1.0 wt % Bi2S3 at 370 K. Furthermore, a high average zT
value (zTave) of 0.93 in the 300–390 K range is demonstrated.

text: 'Endocytosis is a key cellular process involved in the uptake of nutrients,
pathogens, or the therapy of diseases. Most studies have focused on spherical
objects, whereas biologically relevant shapes can be highly anisotropic. In this
letter, we use an experimental model system based on Giant Unilamellar Vesicles
(GUVs) and dumbbell-shaped colloidal particles to mimic and investigate the first
stage of the passive endocytic process: engulfment of an anisotropic object by
the membrane. Our model has specific ligand–receptor interactions realized by
mobile receptors on the vesicles and immobile ligands on the particles. Through
a series of experiments, theory, and molecular dynamics simulations, we quantify
the wrapping process of anisotropic dumbbells by GUVs and identify distinct stages
of the wrapping pathway. We find that the strong curvature variation in the neck
of the dumbbell as well as membrane tension are crucial in determining both the
speed of wrapping and the final states.'

text: Disulfide bond formation is fundamentally important for protein structure
and constitutes a key mechanism by which cells regulate the intracellular oxidation
state. Peroxiredoxins (PRDXs) eliminate reactive oxygen species such as hydrogen
peroxide through a catalytic cycle of Cys oxidation and reduction. Additionally,
upon Cys oxidation PRDXs undergo extensive conformational rearrangements that
may underlie their presently structurally poorly defined functions as molecular
chaperones. Rearrangements include high molecular-weight oligomerization, the
dynamics of which are, however, poorly understood, as is the impact of disulfide
bond formation on these properties. Here we show that formation of disulfide bonds
along the catalytic cycle induces extensive μs time scale dynamics, as monitored
by magic-angle spinning NMR of the 216 kDa-large Tsa1 decameric assembly and solution-NMR
of a designed dimeric mutant. We ascribe the conformational dynamics to structural
frustration, resulting from conflicts between the disulfide-constrained reduction
of mobility and the desire to fulfill other favorable contacts.
