text: The chemical behaviour of molecules can be significantly modified by confinement
to volumes comparable to the dimensions of the molecules. Although such confined
spaces can be found in various nanostructured materials, such as zeolites, nanoporous
organic frameworks and colloidal nanocrystal assemblies, the slow diffusion of
molecules in and out of these materials has greatly hampered studying the effect
of confinement on their physicochemical properties. Here, we show that this diffusion
limitation can be overcome by reversibly creating and destroying confined environments
by means of ultraviolet and visible light irradiation. We use colloidal nanocrystals
functionalized with light-responsive ligands that readily self-assemble and trap
various molecules from the surrounding bulk solution. Once trapped, these molecules
can undergo chemical reactions with increased rates and with stereoselectivities
significantly different from those in bulk solution. Illumination with visible
light disassembles these nanoflasks, releasing the product in solution and thereby
establishes a catalytic cycle. These dynamic nanoflasks can be useful for studying
chemical reactivities in confined environments and for synthesizing molecules
that are otherwise hard to achieve in bulk solution.

text: Precise control of the self-assembly of selected components within complex
mixtures is a challenging goal whose realization is important for fabricating
novel nanomaterials. Herein we show that by decorating the surfaces of metallic
nanoparticles with differently substituted azobenzenes, it is possible to modulate
the wavelength of light at which the self-assembly of these nanoparticles is induced.
Exposing a mixture of two types of nanoparticles, each functionalized with a different
azobenzene, to UV or blue light induces the selective self-assembly of only one
type of nanoparticles. Irradiation with the other wavelength triggers the disassembly
of the aggregates, and the simultaneous self-assembly of nanoparticles of the
other type. By placing both types of azobenzenes on the same nanoparticles, we
created unique materials (“frustrated” nanoparticles) whose self-assembly is induced
irrespective of the wavelength of the incident light.

text: The ability to guide the assembly of nanosized objects reversibly with external
stimuli, in particular light, is of fundamental importance, and it contributes
to the development of applications as diverse as nanofabrication and controlled
drug delivery. However, all the systems described to date are based on nanoparticles
(NPs) that are inherently photoresponsive, which makes their preparation cumbersome
and can markedly hamper their performance. Here we describe a conceptually new
methodology to assemble NPs reversibly using light that does not require the particles
to be functionalized with light-responsive ligands. Our strategy is based on the
use of a photoswitchable medium that responds to light in such a way that it modulates
the interparticle interactions. NP assembly proceeds quantitatively and without
apparent fatigue, both in solution and in gels. Exposing the gels to light in
a spatially controlled manner allowed us to draw images that spontaneously disappeared
after a specific period of time.

ligands were prepared and shown to respond to these two types of stimuli reversibly
and in an orthogonal fashion. The composition of the coating could be tailored
to yield nanoparticles capable of aggregating exclusively when both UV and CO2
were applied at the same time, analogously to the behaviour of an AND logic gate.

text: 'Photoswitching in densely packed azobenzene self-assembled monolayers (SAMs)
is strongly affected by steric constraints and excitonic coupling between neighboring
chromophores. Therefore, control of the chromophore density is essential for enhancing
and manipulating the photoisomerization yield. We systematically compare two methods
to achieve this goal: First, we assemble monocomponent azobenzene–alkanethiolate
SAMs on gold nanoparticles of varying size. Second, we form mixed SAMs of azobenzene–alkanethiolates
and “dummy” alkanethiolates on planar substrates. Both methods lead to a gradual
decrease of the chromophore density and enable efficient photoswitching with low-power
light sources. X-ray spectroscopy reveals that coadsorption from solution yields
mixtures with tunable composition. The orientation of the chromophores with respect
to the surface normal changes from a tilted to an upright position with increasing
azobenzene density. For both systems, optical spectroscopy reveals a pronounced
excitonic shift that increases with the chromophore density. In spite of exciting
the optical transition of the monomer, the main spectral change in mixed SAMs
occurs in the excitonic band. In addition, the photoisomerization yield decreases
only slightly by increasing the azobenzene–alkanethiolate density, and we observed
photoswitching even with minor dilutions. Unlike in solution, azobenzene in the
planar SAM can be switched back almost completely by optical excitation from the
cis to the original trans state within a short time scale. These observations
indicate cooperativity in the photoswitching process of mixed SAMs.'

text: Self-assembly of inorganic nanoparticles has been studied extensively for
particles having different sizes and compositions. However, relatively little
attention has been devoted to how the shape and surface chemistry of magnetic
nanoparticles affects their self-assembly properties. Here, we undertook a combined
experiment–theory study aimed at better understanding of the self-assembly of
cubic magnetite (Fe3O4) particles. We demonstrated that, depending on the experimental
parameters, such as the direction of the magnetic field and nanoparticle density,
a variety of superstructures can be obtained, including one-dimensional filaments
and helices, as well as C-shaped assemblies described here for the first time.
Furthermore, we functionalized the surfaces of the magnetic nanocubes with light-sensitive
ligands. Using these modified nanoparticles, we were able to achieve orthogonal
control of self-assembly using a magnetic field and light.

text: In plants, vacuolar H+-ATPase (V-ATPase) activity acidifies both the trans-Golgi
network/early endosome (TGN/EE) and the vacuole. This dual V-ATPase function has
impeded our understanding of how the pH homeostasis within the plant TGN/EE controls
exo- and endocytosis. Here, we show that the weak V-ATPase mutant deetiolated3
(det3) displayed a pH increase in the TGN/EE, but not in the vacuole, strongly
impairing secretion and recycling of the brassinosteroid receptor and the cellulose
synthase complexes to the plasma membrane, in contrast to mutants lacking tonoplast-localized
V-ATPase activity only. The brassinosteroid insensitivity and the cellulose deficiency
defects in det3 were tightly correlated with reduced Golgi and TGN/EE motility.
Thus, our results provide strong evidence that acidification of the TGN/EE, but
not of the vacuole, is indispensable for functional secretion and recycling in
plants.

text: This thesis is concerned with the computation and approximation of intrinsic
volumes. Given a smooth body M and a certain digital approximation of it, we develop
algorithms to approximate various intrinsic volumes of M using only measurements
taken from its digital approximations. The crucial idea behind our novel algorithms
is to link the recent theory of persistent homology to the theory of intrinsic
volumes via the Crofton formula from integral geometry and, in particular, via
Euler characteristic computations. Our main contributions are a multigrid convergent
digital algorithm to compute the first intrinsic volume of a solid body in R^n
as well as an appropriate integration pipeline to approximate integral-geometric
integrals defined over the Grassmannian manifold.

text: Cancer results from an uncontrolled growth of abnormal cells. Sequentially
accumulated genetic and epigenetic alterations decrease cell death and increase
cell replication. We used mathematical models to quantify the effect of driver
gene mutations. The recently developed targeted therapies can lead to dramatic
regressions. However, in solid cancers, clinical responses are often short-lived
because resistant cancer cells evolve. We estimated that approximately 50 different
mutations can confer resistance to a typical targeted therapeutic agent. We find
that resistant cells are likely to be present in expanded subclones before the
start of the treatment. The dominant strategy to prevent the evolution of resistance
is combination therapy. Our analytical results suggest that in most patients,
dual therapy, but not monotherapy, can result in long-term disease control. However,
long-term control can only occur if there are no possible mutations in the genome
that can cause cross-resistance to both drugs. Furthermore, we showed that simultaneous
therapy with two drugs is much more likely to result in long-term disease control
than sequential therapy with the same drugs. To improve our understanding of the
underlying subclonal evolution we reconstruct the evolutionary history of a patient's
cancer from next-generation sequencing data of spatially-distinct DNA samples.
Using a quantitative measure of genetic relatedness, we found that pancreatic
cancers and their metastases demonstrated a higher level of relatedness than that
expected for any two cells randomly taken from a normal tissue. This minimal amount
of genetic divergence among advanced lesions indicates that genetic heterogeneity,
when quantitatively defined, is not a fundamental feature of the natural history
of untreated pancreatic cancers. Our newly developed, phylogenomic tool Treeomics
finds evidence for seeding patterns of metastases and can directly be used to
discover rules governing the evolution of solid malignancies to transform cancer
into a more predictable disease.

text: 'The human ability to recognize objects in complex scenes has driven research
in the computer vision field over couple of decades. This thesis focuses on the
object recognition task in images. That is, given the image, we want the computer
system to be able to predict the class of the object that appears in the image.
A recent successful attempt to bridge semantic understanding of the image perceived
by humans and by computers uses attribute-based models. Attributes are semantic
properties of the objects shared across different categories, which humans and
computers can decide on. To explore the attribute-based models we take a statistical
machine learning approach, and address two key learning challenges in view of
object recognition task: learning augmented attributes as mid-level discriminative
feature representation, and learning with attributes as privileged information.
Our main contributions are parametric and non-parametric models and algorithms
to solve these frameworks. In the parametric approach, we explore an autoencoder
model combined with the large margin nearest neighbor principle for mid-level
feature learning, and linear support vector machines for learning with privileged
information. In the non-parametric approach, we propose a supervised Indian Buffet
Process for automatic augmentation of semantic attributes, and explore the Gaussian
Processes classification framework for learning with privileged information. A
thorough experimental analysis shows the effectiveness of the proposed models
in both parametric and non-parametric views.'

text: The ultrafast motion of electrons and holes after light-matter interaction
is fundamental to a broad range of chemical and biophysical processes. We advanced
high-harmonic spectroscopy to resolve spatially and temporally the migration of
an electron hole immediately after ionization of iodoacetylene while simultaneously
demonstrating extensive control over the process. A multidimensional approach,
based on the measurement and accurate theoretical description of both even and
odd harmonic orders, enabled us to reconstruct both quantum amplitudes and phases
of the electronic states with a resolution of ~100 attoseconds. We separately
reconstructed quasi-field-free and laser-controlled charge migration as a function
of the spatial orientation of the molecule and determined the shape of the hole
created by ionization. Our technique opens the prospect of laser control over
electronic primary processes.

text: We have studied a coupled electronic-nuclear wave packet in nitric oxide using
time-resolved strong-field photoelectron holography and rescattering. We show
that the electronic dynamics mainly appears in the holographic structures whereas
nuclear motion strongly modulates the angular distribution of the rescattered
photoelectrons.

text: All attosecond time-resolved measurements have so far relied on the use of
intense near-infrared laser pulses. In particular, attosecond streaking, laser-induced
electron diffraction and high-harmonic generation all make use of non-perturbative
light–matter interactions. Remarkably, the effect of the strong laser field on
the studied sample has often been neglected in previous studies. Here we use high-harmonic
spectroscopy to measure laser-induced modifications of the electronic structure
of molecules. We study high-harmonic spectra of spatially oriented CH3F and CH3Br
as generic examples of polar polyatomic molecules. We accurately measure intensity
ratios of even and odd-harmonic orders, and of the emission from aligned and unaligned
molecules. We show that these robust observables reveal a substantial modification
of the molecular electronic structure by the external laser field. Our insights
offer new challenges and opportunities for a range of emerging strong-field attosecond
spectroscopies.

text: The detection of electron motion and electronic wave-packet dynamics is one
of the core goals of attosecond science. Recently, choosing the nitric oxide molecule
as an example, we have introduced and demonstrated an experimental approach to
measure coupled valence electronic and rotational wave packets using high-order-harmonic-generation
(HHG) spectroscopy [Kraus et al., Phys. Rev. Lett. 111, 243005 (2013)]. A short
outline of the theory to describe the combination of the pump and HHG probe process
was published together with an extensive discussion of experimental results [Baykusheva
et al., Faraday Discuss. 171, 113 (2014)]. The comparison of theory and experiment
showed good agreement on a quantitative level. Here, we present the theory in
detail, which is based on a generalized density-matrix approach that describes
the pump process and the subsequent probing of the wave packets by a semiclassical
quantitative rescattering approach. An in-depth analysis of the different Raman
scattering contributions to the creation of the coupled rotational and electronic
spin-orbit wave packets is made. We present results for parallel and perpendicular
linear polarizations of the pump and probe laser pulses. Furthermore, an analysis
of the combined rotational-electronic density matrix in terms of irreducible components
is presented that facilitates interpretation of the results.

text: We consider the problem of statistical computations with persistence diagrams,
a summary representation of topological features in data. These diagrams encode
persistent homology, a widely used invariant in topological data analysis. While
several avenues towards a statistical treatment of the diagrams have been explored
recently, we follow an alternative route that is motivated by the success of methods
based on the embedding of probability measures into reproducing kernel Hilbert
spaces. In fact, a positive definite kernel on persistence diagrams has recently
been proposed, connecting persistent homology to popular kernel-based learning
techniques such as support vector machines. However, important properties of that
kernel enabling a principled use in the context of probability measure embeddings
remain to be explored. Our contribution is to close this gap by proving universality
of a variant of the original kernel, and to demonstrate its effective use in twosample
hypothesis testing on synthetic as well as real-world data.

text: 'In this work we aim at extending the theoretical foundations of lifelong
learning. Previous work analyzing this scenario is based on the assumption that
learning tasks are sampled i.i.d. from a task environment or limited to strongly
constrained data distributions. Instead, we study two scenarios when lifelong
learning is possible, even though the observed tasks do not form an i.i.d. sample:
first, when they are sampled from the same environment, but possibly with dependencies,
and second, when the task environment is allowed to change over time in a consistent
way. In the first case we prove a PAC-Bayesian theorem that can be seen as a direct
generalization of the analogous previous result for the i.i.d. case. For the second
scenario we propose to learn an inductive bias in form of a transfer procedure.
We present a generalization bound and show on a toy example how it can be used
to identify a beneficial transfer algorithm.'

text: Evolutionary algorithms (EAs) form a popular optimisation paradigm inspired
by natural evolution. In recent years the field of evolutionary computation has
developed a rigorous analytical theory to analyse their runtime on many illustrative
problems. Here we apply this theory to a simple model of natural evolution. In
the Strong Selection Weak Mutation (SSWM) evolutionary regime the time between
occurrence of new mutations is much longer than the time it takes for a new beneficial
mutation to take over the population. In this situation, the population only contains
copies of one genotype and evolution can be modelled as a (1+1)-type process where
the probability of accepting a new genotype (improvements or worsenings) depends
on the change in fitness. We present an initial runtime analysis of SSWM, quantifying
its performance for various parameters and investigating differences to the (1+1)
EA. We show that SSWM can have a moderate advantage over the (1+1) EA at crossing
fitness valleys and study an example where SSWM outperforms the (1+1) EA by taking
advantage of information on the fitness gradient.

text: Scaffolded DNA origami enables the fabrication of a variety of complex nanostructures
that promise utility in diverse fields of application, ranging from biosensing
over advanced therapeutics to metamaterials. The broad applicability of DNA origami
as a material beyond the level of proof-of-concept studies critically depends,
among other factors, on the availability of large amounts of pure single-stranded
scaffold DNA. Here, we present a method for the efficient production of M13 bacteriophage-derived
genomic DNA using high-cell-density fermentation of Escherichia coli in stirred-tank
bioreactors. We achieve phage titers of up to 1.6 × 1014 plaque-forming units
per mL. Downstream processing yields up to 410 mg of high-quality single-stranded
DNA per one liter reaction volume, thus upgrading DNA origami-based nanotechnology
from the milligram to the gram scale.
