text: 'High-performance semiconductors rely upon precise control of heat and charge
transport. This can be achieved by precisely engineering defects in polycrystalline
solids. There are multiple approaches to preparing such polycrystalline semiconductors,
and the transformation of solution-processed colloidal nanoparticles is appealing
because colloidal nanoparticles combine low cost with structural and compositional
tunability along with rich surface chemistry. However, the multiple processes
from nanoparticle synthesis to the final bulk nanocomposites are very complex.
They involve nanoparticle purification, post-synthetic modifications, and finally
consolidation (thermal treatments and densification). All these properties dictate
the final material’s composition and microstructure, ultimately affecting its
functional properties. This thesis explores the synthesis, surface chemistry and
consolidation of colloidal semiconductor nanoparticles into dense solids. In particular,
the transformations that take place during these processes, and their effect on
the material’s transport properties are evaluated. '

text: We introduce a stochastic cellular automaton as a model for culture and border
formation. The model can be conceptualized as a game where the expansion rate
of cultures is quantified in terms of their area and perimeter in such a way that
approximately geometrically round cultures get a competitive advantage. We first
analyze the model with periodic boundary conditions, where we study how the model
can end up in a fixed state, i.e., freezes. Then we implement the model on the
European geography with mountains and rivers. We see how the model reproduces
some qualitative features of European culture formation, namely, that rivers and
mountains are more frequently borders between cultures, mountainous regions tend
to have higher cultural diversity, and the central European plain has less clear
cultural borders.

text: "The tight spatiotemporal coordination of signaling activity determining embryo\r\npatterning
and the physical processes driving embryo morphogenesis renders\r\nembryonic development
robust, such that key developmental processes can unfold\r\nrelatively normally
even outside of the full embryonic context. For instance, embryonic\r\nstem cell
cultures can recapitulate the hallmarks of gastrulation, i.e. break symmetry\r\nleading
to germ layer formation and morphogenesis, in a very reduced environment.\r\nThis
leads to questions on specific contributions of embryo-specific features, such
as\r\nthe presence of extraembryonic tissues, which are inherently involved in
gastrulation\r\nin the full embryonic context. To address this, we established
zebrafish embryonic\r\nexplants without the extraembryonic yolk cell, an important
player as a signaling\r\nsource and for morphogenesis during gastrulation, as
a model of ex vivo development.\r\nWe found that dorsal-marginal determinants
are required and sufficient in these\r\nexplants to form and pattern all three
germ layers. However, formation of tissues,\r\nwhich require the highest Nodal-signaling
levels, is variable, demonstrating a\r\ncontribution of extraembryonic tissues
for reaching peak Nodal signaling levels.\r\nBlastoderm explants also undergo
gastrulation-like axis elongation. We found that this\r\nelongation movement shows
hallmarks of oriented mesendoderm cell intercalations\r\ntypically associated
with dorsal tissues in the intact embryo. These are disrupted by\r\nuniform upregulation
of BMP signaling activity and concomitant explant ventralization,\r\nsuggesting
that tight spatial control of BMP signaling is a prerequisite for explant\r\nmorphogenesis.
This control is achieved by Nodal signaling, which is critical for\r\neffectively
downregulating BMP signaling in the mesendoderm, highlighting that Nodal\r\nsignaling
is not only directly required for mesendoderm cell fate specification and\r\nmorphogenesis,
but also by maintaining low levels of BMP signaling at the dorsal side.\r\nCollectively,
we provide insights into the capacity and organization of signaling and\r\nmorphogenetic
domains to recapitulate features of zebrafish gastrulation outside of\r\nthe full
embryonic context."

text: "Inverse design problems in fabrication-aware shape optimization are typically
solved on discrete representations such as polygonal meshes. This thesis argues
that there are benefits to treating these problems in the same domain as human
designers, namely, the parametric one. One reason is that discretizing a parametric
model usually removes the capability of making further manual changes to the design,
because the human intent is captured by the shape parameters. Beyond this, knowledge
about a design problem can sometimes reveal a structure that is present in a smooth
representation, but is fundamentally altered by discretizing. In this case, working
in the parametric domain may even simplify the optimization task. We present two
lines of research that explore both of these aspects of fabrication-aware shape
optimization on parametric representations.\r\n\r\nThe first project studies the
design of plane elastic curves and Kirchhoff rods, which are common mathematical
models for describing the deformation of thin elastic rods such as beams, ribbons,
cables, and hair. Our main contribution is a characterization of all curved shapes
that can be attained by bending and twisting elastic rods having a stiffness that
is allowed to vary across the length. Elements like these can be manufactured
using digital fabrication devices such as 3d printers and digital cutters, and
have applications in free-form architecture and soft robotics.\r\n\r\nWe show
that the family of curved shapes that can be produced this way admits geometric
description that is concise and computationally convenient. In the case of plane
curves, the geometric description is intuitive enough to allow a designer to determine
whether a curved shape is physically achievable by visual inspection alone. We
also present shape optimization algorithms that convert a user-defined curve in
the plane or in three dimensions into the geometry of an elastic rod that will
naturally deform to follow this curve when its endpoints are attached to a support
structure. Implemented in an interactive software design tool, the rod geometry
is generated in real time as the user edits a curve and enables fast prototyping.
\r\n\r\nThe second project tackles the problem of general-purpose shape optimization
on CAD models using a novel variant of the extended finite element method (XFEM).
Our goal is the decoupling between the simulation mesh and the CAD model, so no
geometry-dependent meshing or remeshing needs to be performed when the CAD parameters
change during optimization. This is achieved by discretizing the embedding space
of the CAD model, and using a new high-accuracy numerical integration method to
enable XFEM on free-form elements bounded by the parametric surface patches of
the model. Our simulation is differentiable from the CAD parameters to the simulation
output, which enables us to use off-the-shelf gradient-based optimization procedures.
The result is a method that fits seamlessly into the CAD workflow because it works
on the same representation as the designer, enabling the alternation of manual
editing and fabrication-aware optimization at will."

text: "About a 100 years ago, we discovered that our universe is inherently noisy,
that is, measuring any physical quantity with a precision beyond a certain point
is not possible because of an omnipresent inherent noise. We call this - the quantum
noise. Certain physical processes allow this quantum noise to get correlated in
conjugate physical variables. These quantum correlations can be used to go beyond
the potential of our inherently noisy universe and obtain a quantum advantage
over the classical applications. \r\n\r\nQuantum noise being inherent also means
that, at the fundamental level, the physical quantities are not well defined and
therefore, objects can stay in multiple states at the same time. For example,
the position of a particle not being well defined means that the particle is in
multiple positions at the same time. About 4 decades ago, we started exploring
the possibility of using objects which can be in multiple states at the same time
to increase the dimensionality in computation. Thus, the field of quantum computing
was born. We discovered that using quantum entanglement, a property closely related
to quantum correlations, can be used to speed up computation of certain problems,
such as factorisation of large numbers, faster than any known classical algorithm.
Thus began the pursuit to make quantum computers a reality. \r\n\r\nTill date,
we have explored quantum control over many physical systems including photons,
spins, atoms, ions and even simple circuits made up of superconducting material.
However, there persists one ubiquitous theme. The more readily a system interacts
with an external field or matter, the more easily we can control it. But this
also means that such a system can easily interact with a noisy environment and
quickly lose its coherence. Consequently, such systems like electron spins need
to be protected from the environment to ensure the longevity of their coherence.
Other systems like nuclear spins are naturally protected as they do not interact
easily with the environment. But, due to the same reason, it is harder to interact
with such systems. \r\n\r\nAfter decades of experimentation with various systems,
we are convinced that no one type of quantum system would be the best for all
the quantum applications. We would need hybrid systems which are all interconnected
- much like the current internet where all sorts of devices can all talk to each
other - but now for quantum devices. A quantum internet. \r\n\r\nOptical photons
are the best contenders to carry information for the quantum internet. They can
carry quantum information cheaply and without much loss - the same reasons which
has made them the backbone of our current internet. Following this direction,
many systems, like trapped ions, have already demonstrated successful quantum
links over a large distances using optical photons. However, some of the most
promising contenders for quantum computing which are based on microwave frequencies
have been left behind. This is because high energy optical photons can adversely
affect fragile low-energy microwave systems. \r\n\r\nIn this thesis, we present
substantial progress on this missing quantum link between microwave and optics
using electrooptical nonlinearities in lithium niobate. The nonlinearities are
enhanced by using resonant cavities for all the involved modes leading to observation
of strong direct coupling between optical and microwave frequencies. With this
strong coupling we are not only able to achieve almost 100\\% internal conversion
efficiency with low added noise, thus presenting a quantum-enabled transducer,
but also we are able to observe novel effects such as cooling of a microwave mode
using optics. The strong coupling regime also leads to direct observation of dynamical
backaction effect between microwave and optical frequencies which are studied
in detail here. Finally, we also report first observation of microwave-optics
entanglement in form of two-mode squeezed vacuum squeezed 0.7dB below vacuum level.
\r\nWith this new bridge between microwave and optics, the microwave-based quantum
technologies can finally be a part of a quantum network which is based on optical
photons - putting us one step closer to a future with quantum internet. "

text: 'This paper establishes new connections between many-body quantum systems,
One-body Reduced Density Matrices Functional Theory (1RDMFT) and Optimal Transport
(OT), by interpreting the problem of computing the ground-state energy of a finite-dimensional
composite quantum system at positive temperature as a non-commutative entropy
regularized Optimal Transport problem. We develop a new approach to fully characterize
the dual-primal solutions in such non-commutative setting. The mathematical formalism
is particularly relevant in quantum chemistry: numerical realizations of the many-electron
ground-state energy can be computed via a non-commutative version of Sinkhorn
algorithm. Our approach allows to prove convergence and robustness of this algorithm,
which, to our best knowledge, were unknown even in the two marginal case. Our
methods are based on a priori estimates in the dual problem, which we believe
to be of independent interest. Finally, the above results are extended in 1RDMFT
setting, where bosonic or fermionic symmetry conditions are enforced on the problem.'

text: The chemical potential of adsorbed or confined fluids provides insight into
their unique thermodynamic properties and determines adsorption isotherms. However,
it is often difficult to compute this quantity from atomistic simulations using
existing statistical mechanical methods. We introduce a computational framework
that utilizes static structure factors, thermodynamic integration, and free energy
perturbation for calculating the absolute chemical potential of fluids. For demonstration,
we apply the method to compute the adsorption isotherms of carbon dioxide in a
metal-organic framework and water in carbon nanotubes.

text: The coexistence of gate-tunable superconducting, magnetic and topological
orders in magic-angle twisted bilayer graphene provides opportunities for the
creation of hybrid Josephson junctions. Here we report the fabrication of gate-defined
symmetry-broken Josephson junctions in magic-angle twisted bilayer graphene, where
the weak link is gate-tuned close to the correlated insulator state with a moiré
filling factor of υ = −2. We observe a phase-shifted and asymmetric Fraunhofer
pattern with a pronounced magnetic hysteresis. Our theoretical calculations of
the junction weak link—with valley polarization and orbital magnetization—explain
most of these unconventional features. The effects persist up to the critical
temperature of 3.5 K, with magnetic hysteresis observed below 800 mK. We show
how the combination of magnetization and its current-induced magnetization switching
allows us to realise a programmable zero-field superconducting diode. Our results
represent a major advance towards the creation of future superconducting quantum
electronic devices.

text: We numerically study two methods of measuring tunneling times using a quantum
clock. In the conventional method using the Larmor clock, we show that the Larmor
tunneling time can be shorter for higher tunneling barriers. In the second method,
we study the probability of a spin-flip of a particle when it is transmitted through
a potential barrier including a spatially rotating field interacting with its
spin. According to the adiabatic theorem, the probability depends on the velocity
of the particle inside the barrier. It is numerically observed that the probability
increases for higher barriers, which is consistent with the result obtained by
the Larmor clock. By comparing outcomes for different initial spin states, we
suggest that one of the main causes of the apparent decrease in the tunneling
time can be the filtering effect occurring at the end of the barrier.

text: Cu2–xS and Cu2–xSe have recently been reported as promising thermoelectric
(TE) materials for medium-temperature applications. In contrast, Cu2–xTe, another
member of the copper chalcogenide family, typically exhibits low Seebeck coefficients
that limit its potential to achieve a superior thermoelectric figure of merit,
zT, particularly in the low-temperature range where this material could be effective.
To address this, we investigated the TE performance of Cu1.5–xTe–Cu2Se nanocomposites
by consolidating surface-engineered Cu1.5Te nanocrystals. This surface engineering
strategy allows for precise adjustment of Cu/Te ratios and results in a reversible
phase transition at around 600 K in Cu1.5–xTe–Cu2Se nanocomposites, as systematically
confirmed by in situ high-temperature X-ray diffraction combined with differential
scanning calorimetry analysis. The phase transition leads to a conversion from
metallic-like to semiconducting-like TE properties. Additionally, a layer of Cu2Se
generated around Cu1.5–xTe nanoparticles effectively inhibits Cu1.5–xTe grain
growth, minimizing thermal conductivity and decreasing hole concentration. These
properties indicate that copper telluride based compounds have a promising thermoelectric
potential, translated into a high dimensionless zT of 1.3 at 560 K.

text: The classical infinitesimal model is a simple and robust model for the inheritance
of quantitative traits. In this model, a quantitative trait is expressed as the
sum of a genetic and a non-genetic (environmental) component and the genetic component
of offspring traits within a family follows a normal distribution around the average
of the parents’ trait values, and has a variance that is independent of the trait
values of the parents. Although the trait distribution across the whole population
can be far from normal, the trait distributions within families are normally distributed
with a variance-covariance matrix that is determined entirely by that in the
ancestral population and the probabilities of identity determined by the pedigree.
Moreover, conditioning on some of the trait values within the pedigree has predictable
effects on the mean and variance within and between families. In previous work,
Barton et al. (2017), we showed that when trait values are determined by the sum
of a large number of Mendelian factors, each of small effect, one can justify
the infinitesimal model as limit of Mendelian inheritance. It was also shown that
under some forms of epistasis, trait values within a family are still normally
distributed.

text: "This paper deals with the large-scale behaviour of dynamical optimal transport
on Zd\r\n-periodic graphs with general lower semicontinuous and convex energy
densities. Our main contribution is a homogenisation result that describes the
effective behaviour of the discrete problems in terms of a continuous optimal
transport problem. The effective energy density can be explicitly expressed in
terms of a cell formula, which is a finite-dimensional convex programming problem
that depends non-trivially on the local geometry of the discrete graph and the
discrete energy density. Our homogenisation result is derived from a Γ\r\n-convergence
result for action functionals on curves of measures, which we prove under very
mild growth conditions on the energy density. We investigate the cell formula
in several cases of interest, including finite-volume discretisations of the Wasserstein
distance, where non-trivial limiting behaviour occurs."

text: "Isomanifolds are the generalization of isosurfaces to arbitrary dimension
and codimension, i.e., submanifolds of Rd defined as the zero set of some multivariate
multivalued smooth function f:Rd→Rd−n, where n is the intrinsic dimension of the
manifold. A natural way to approximate a smooth isomanifold M=f−1(0) is to consider
its piecewise linear (PL) approximation M^\r\n based on a triangulation T of the
ambient space Rd. In this paper, we describe a simple algorithm to trace isomanifolds
from a given starting point. The algorithm works for arbitrary dimensions n and
d, and any precision D. Our main result is that, when f (or M) has bounded complexity,
the complexity of the algorithm is polynomial in d and δ=1/D (and unavoidably
exponential in n). Since it is known that for δ=Ω(d2.5), M^ is O(D2)-close and
isotopic to M\r\n, our algorithm produces a faithful PL-approximation of isomanifolds
of bounded complexity in time polynomial in d. Combining this algorithm with dimensionality
reduction techniques, the dependency on d in the size of M^ can be completely
removed with high probability. We also show that the algorithm can handle isomanifolds
with boundary and, more generally, isostratifolds. The algorithm for isomanifolds
with boundary has been implemented and experimental results are reported, showing
that it is practical and can handle cases that are far ahead of the state-of-the-art. "

text: 'Two notes separated by a doubling in frequency sound similar to humans. This
“octave equivalence” is critical to perception and production of music and speech
and occurs early in human development. Because it also occurs cross-culturally,
a biological basis of octave equivalence has been hypothesized. Members of our
team previousy suggested four human traits are at the root of this phenomenon:
(1) vocal learning, (2) clear octave information in vocal harmonics, (3) differing
vocal ranges, and (4) vocalizing together. Using cross-species studies, we can
test how relevant these respective traits are, while controlling for enculturation
effects and addressing questions of phylogeny. Common marmosets possess forms
of three of the four traits, lacking differing vocal ranges. We tested 11 common
marmosets by adapting an established head-turning paradigm, creating a parallel
test to an important infant study. Unlike human infants, marmosets responded similarly
to tones shifted by an octave or other intervals. Because previous studies with
the same head-turning paradigm produced differential results to discernable acoustic
stimuli in common marmosets, our results suggest that marmosets do not perceive
octave equivalence. Our work suggests differing vocal ranges between adults and
children and men and women and the way they are used in singing together may be
critical to the development of octave equivalence.'

text: "Pattern formation is of great importance for its contribution across different
biological behaviours. During developmental processes for example, patterns of
chemical gradients are\r\nestablished to determine cell fate and complex tissue
patterns emerge to define structures such\r\nas limbs and vascular networks. Patterns
are also seen in collectively migrating groups, for\r\ninstance traveling waves
of density emerging in moving animal flocks as well as collectively migrating
cells and tissues. To what extent these biological patterns arise spontaneously
through\r\nthe local interaction of individual constituents or are dictated by
higher level instructions is\r\nstill an open question however there is evidence
for the involvement of both types of process.\r\nWhere patterns arise spontaneously
there is a long standing interest in how far the interplay\r\nof mechanics, e.g.
force generation and deformation, and chemistry, e.g. gene regulation\r\nand signaling,
contributes to the behaviour. This is because many systems are able to both\r\nchemically
regulate mechanical force production and chemically sense mechanical deformation,\r\nforming
mechano-chemical feedback loops which can potentially become unstable towards\r\nspatio
and/or temporal patterning.\r\nWe work with experimental collaborators to investigate
the possibility that this type of\r\ninteraction drives pattern formation in biological
systems at different scales. We focus first on\r\ntissue-level ERK-density waves
observed during the wound healing response across different\r\nsystems where many
previous studies have proposed that patterns depend on polarized cell\r\nmigration
and arise from a mechanical flocking-like mechanism. By combining theory with\r\nmechanical
and optogenetic perturbation experiments on in vitro monolayers we instead find\r\nevidence
for mechanochemical pattern formation involving only scalar bilateral feedbacks\r\nbetween
ERK signaling and cell contraction. We perform further modeling and experiment\r\nto
study how this instability couples with polar cell migration in order to produce
a robust\r\nand efficient wound healing response. In a following chapter we implement
ERK-density\r\ncoupling and cell migration in a 2D active vertex model to investigate
the interaction of\r\nERK-density patterning with different tissue rheologies
and find that the spatio-temporal\r\ndynamics are able to both locally and globally
fluidize a tissue across the solid-fluid glass\r\ntransition. In a last chapter
we move towards lower spatial scales in the context of subcellular\r\npatterning
of the cell cytoskeleton where we investigate the transition between phases of\r\nspatially
homogeneous temporal oscillations and chaotic spatio-temporal patterning in the\r\ndynamics
of myosin and ROCK activities (a motor component of the actomyosin cytoskeleton\r\nand
its activator). Experimental evidence supports an intrinsic chemical oscillator
which we\r\nencode in a reaction model and couple to a contractile active gel
description of the cell cortex.\r\nThe model exhibits phases of chemical oscillations
and contractile spatial patterning which\r\nreproduce many features of the dynamics
seen in Drosophila oocyte epithelia in vivo. However,\r\nadditional pharmacological
perturbations to inhibit myosin contractility leaves the role of\r\ncontractile
instability unclear. We discuss alternative hypotheses and investigate the possibility\r\nof
reaction-diffusion instability."

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."
