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 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: Parasitism creates selection for resistance mechanisms in host populations
and is hypothesized to promote increased host evolvability. However, the influence
of these traits on host evolution when parasites are no longer present is unclear.
We used experimental evolution and whole-genome sequencing of Escherichia coli
to determine the effects of past and present exposure to parasitic viruses (phages)
on the spread of mutator alleles, resistance, and bacterial competitive fitness.
We found that mutator alleles spread rapidly during adaptation to any of four
different phage species, and this pattern was even more pronounced with multiple
phages present simultaneously. However, hypermutability did not detectably accelerate
adaptation in the absence of phages and recovery of fitness costs associated with
resistance. Several lineages evolved phage resistance through elevated mucoidy,
and during subsequent evolution in phage-free conditions they rapidly reverted
to nonmucoid, phage-susceptible phenotypes. Genome sequencing revealed that this
phenotypic reversion was achieved by additional genetic changes rather than by
genotypic reversion of the initial resistance mutations. Insertion sequence (IS)
elements played a key role in both the acquisition of resistance and adaptation
in the absence of parasites; unlike single nucleotide polymorphisms, IS insertions
were not more frequent in mutator lineages. Our results provide a genetic explanation
for rapid reversion of mucoidy, a phenotype observed in other bacterial species
including human pathogens. Moreover, this demonstrates that the types of genetic
change underlying adaptation to fitness costs, and consequently the impact of
evolvability mechanisms such as increased point-mutation rates, depend critically
on the mechanism of resistance.

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 competition for resources among cells, individuals or species is a fundamental
characteristic of evolution. Biological all-pay auctions have been used to model
situations where multiple individuals compete for a single resource. However,
in many situations multiple resources with various values exist and single reward
auctions are not applicable. We generalize the model to multiple rewards and study
the evolution of strategies. In biological all-pay auctions the bid of an individual
corresponds to its strategy and is equivalent to its payment in the auction. The
decreasingly ordered rewards are distributed according to the decreasingly ordered
bids of the participating individuals. The reproductive success of an individual
is proportional to its fitness given by the sum of the rewards won minus its payments.
Hence, successful bidding strategies spread in the population. We find that the
results for the multiple reward case are very different from the single reward
case. While the mixed strategy equilibrium in the single reward case with more
than two players consists of mostly low-bidding individuals, we show that the
equilibrium can convert to many high-bidding individuals and a few low-bidding
individuals in the multiple reward case. Some reward values lead to a specialization
among the individuals where one subpopulation competes for the rewards and the
other subpopulation largely avoids costly competitions. Whether the mixed strategy
equilibrium is an evolutionarily stable strategy (ESS) depends on the specific
values of the rewards.

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: Motivated by recent ideas of Harman (Unif. Distrib. Theory, 2010) we develop
a new concept of variation of multivariate functions on a compact Hausdorff space
with respect to a collection D of subsets. We prove a general version of the Koksma-Hlawka
theorem that holds for this notion of variation and discrepancy with respect to
D. As special cases, we obtain Koksma-Hlawka inequalities for classical notions,
such as extreme or isotropic discrepancy. For extreme discrepancy, our result
coincides with the usual Koksma-Hlawka theorem. We show that the space of functions
of bounded D-variation contains important discontinuous functions and is closed
under natural algebraic operations. Finally, we illustrate the results on concrete
integration problems from integral geometry and stereology.

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: Evolution of gene regulation is crucial for our understanding of the phenotypic
differences between species, populations and individuals. Sequence-specific binding
of transcription factors to the regulatory regions on the DNA is a key regulatory
mechanism that determines gene expression and hence heritable phenotypic variation.
We use a biophysical model for directional selection on gene expression to estimate
the rates of gain and loss of transcription factor binding sites (TFBS) in finite
populations under both point and insertion/deletion mutations. Our results show
that these rates are typically slow for a single TFBS in an isolated DNA region,
unless the selection is extremely strong. These rates decrease drastically with
increasing TFBS length or increasingly specific protein-DNA interactions, making
the evolution of sites longer than ∼ 10 bp unlikely on typical eukaryotic speciation
timescales. Similarly, evolution converges to the stationary distribution of binding
sequences very slowly, making the equilibrium assumption questionable. The availability
of longer regulatory sequences in which multiple binding sites can evolve simultaneously,
the presence of “pre-sites” or partially decayed old sites in the initial sequence,
and biophysical cooperativity between transcription factors, can all facilitate
gain of TFBS and reconcile theoretical calculations with timescales inferred from
comparative genomics.

text: We extend the theory of input-output conformance with operators for merge
and quotient. The former is useful when testing against multiple requirements
or views. The latter can be used to generate tests for patches of an already tested
system. Both operators can combine systems with different action alphabets, which
is usually the case when constructing complex systems and specifications from
parts, for instance different views as well as newly defined functionality of
a~previous version of the system.

text: 'We consider Markov decision processes (MDPs) which are a standard model for
probabilistic systems. We focus on qualitative properties for MDPs that can express
that desired behaviors of the system arise almost-surely (with probability 1)
or with positive probability. We introduce a new simulation relation to capture
the refinement relation of MDPs with respect to qualitative properties, and present
discrete graph algorithms with quadratic complexity to compute the simulation
relation. We present an automated technique for assume-guarantee style reasoning
for compositional analysis of two-player games by giving a counterexample guided
abstraction-refinement approach to compute our new simulation relation. We show
a tight link between two-player games and MDPs, and as a consequence the results
for games are lifted to MDPs with qualitative properties. We have implemented
our algorithms and show that the compositional analysis leads to significant improvements. '

text: Interprocedural analysis is at the heart of numerous applications in programming
languages, such as alias analysis, constant propagation, etc. Recursive state
machines (RSMs) are standard models for interprocedural analysis. We consider
a general framework with RSMs where the transitions are labeled from a semiring,
and path properties are algebraic with semiring operations. RSMs with algebraic
path properties can model interprocedural dataflow analysis problems, the shortest
path problem, the most probable path problem, etc. The traditional algorithms
for interprocedural analysis focus on path properties where the starting point
is fixed as the entry point of a specific method. In this work, we consider possible
multiple queries as required in many applications such as in alias analysis. The
study of multiple queries allows us to bring in a very important algorithmic distinction
between the resource usage of the one-time preprocessing vs for each individual
query. The second aspect that we consider is that the control flow graphs for
most programs have constant treewidth. Our main contributions are simple and implementable
algorithms that supportmultiple queries for algebraic path properties for RSMs
that have constant treewidth. Our theoretical results show that our algorithms
have small additional one-time preprocessing, but can answer subsequent queries
significantly faster as compared to the current best-known solutions for several
important problems, such as interprocedural reachability and shortest path. We
provide a prototype implementation for interprocedural reachability and intraprocedural
shortest path that gives a significant speed-up on several benchmarks.

text: We consider the quantitative analysis problem for interprocedural control-flow
graphs (ICFGs). The input consists of an ICFG, a positive weight function that
assigns every transition a positive integer-valued number, and a labelling of
the transitions (events) as good, bad, and neutral events. The weight function
assigns to each transition a numerical value that represents ameasure of how good
or bad an event is. The quantitative analysis problem asks whether there is a
run of the ICFG where the ratio of the sum of the numerical weights of good events
versus the sum of weights of bad events in the long-run is at least a given threshold
(or equivalently, to compute the maximal ratio among all valid paths in the ICFG).
The quantitative analysis problem for ICFGs can be solved in polynomial time,
and we present an efficient and practical algorithm for the problem. We show that
several problems relevant for static program analysis, such as estimating the
worst-case execution time of a program or the average energy consumption of a
mobile application, can be modeled in our framework. We have implemented our algorithm
as a tool in the Java Soot framework. We demonstrate the effectiveness of our
approach with two case studies. First, we show that our framework provides a sound
approach (no false positives) for the analysis of inefficiently-used containers.
Second, we show that our approach can also be used for static profiling of programs
which reasons about methods that are frequently invoked. Our experimental results
show that our tool scales to relatively large benchmarks, and discovers relevant
and useful information that can be used to optimize performance of the programs.

text: We consider the core algorithmic problems related to verification of systems
with respect to three classical quantitative properties, namely, the mean-payoff
property, the ratio property, and the minimum initial credit for energy property.
The algorithmic problem given a graph and a quantitative property asks to compute
the optimal value (the infimum value over all traces) from every node of the graph.
We consider graphs with constant treewidth, and it is well-known that the control-flow
graphs of most programs have constant treewidth. Let n denote the number of nodes
of a graph, m the number of edges (for constant treewidth graphs m=O(n)) and W
the largest absolute value of the weights. Our main theoretical results are as
follows. First, for constant treewidth graphs we present an algorithm that approximates
the mean-payoff value within a multiplicative factor of ϵ in time O(n⋅log(n/ϵ))
and linear space, as compared to the classical algorithms that require quadratic
time. Second, for the ratio property we present an algorithm that for constant
treewidth graphs works in time O(n⋅log(|a⋅b|))=O(n⋅log(n⋅W)), when the output
is ab, as compared to the previously best known algorithm with running time O(n2⋅log(n⋅W)).
Third, for the minimum initial credit problem we show that (i) for general graphs
the problem can be solved in O(n2⋅m) time and the associated decision problem
can be solved in O(n⋅m) time, improving the previous known O(n3⋅m⋅log(n⋅W)) and
O(n2⋅m) bounds, respectively; and (ii) for constant treewidth graphs we present
an algorithm that requires O(n⋅logn) time, improving the previous known O(n4⋅log(n⋅W))
bound. We have implemented some of our algorithms and show that they present a
significant speedup on standard benchmarks.

text: 'We present a flexible framework for the automated competitive analysis of
on-line scheduling algorithms for firm-deadline real-time tasks based on multi-objective
graphs: Given a task set and an on-line scheduling algorithm specified as a labeled
transition system, along with some optional safety, liveness, and/or limit-average
constraints for the adversary, we automatically compute the competitive ratio
of the algorithm w.r.t. A clairvoyant scheduler. We demonstrate the flexibility
and power of our approach by comparing the competitive ratio of several on-line
algorithms, including Dover, that have been proposed in the past, for various
task sets. Our experimental results reveal that none of these algorithms is universally
optimal, in the sense that there are task sets where other schedulers provide
better performance. Our framework is hence a very useful design tool for selecting
optimal algorithms for a given application.'

text: "We present a method for simulating brittle fracture under the assumptions
of quasi-static linear elastic fracture mechanics (LEFM). Using the boundary element
method (BEM) and Lagrangian crack-fronts, we produce highly detailed fracture
surfaces. The computational cost of the BEM is alleviated by using a low-resolution
mesh and interpolating the resulting stress intensity factors when propagating
the high-resolution crack-front.\r\n\r\nOur system produces physics-based fracture
surfaces with high spatial and temporal resolution, taking spatial variation of
material toughness and/or strength into account. It also allows for crack initiation
to be handled separately from crack propagation, which is not only more reasonable
from a physics perspective, but can also be used to control the simulation.\r\n\r\nSeparating
the resolution of the crack-front from the resolution of the computational mesh
increases the efficiency and therefore the amount of visual detail on the resulting
fracture surfaces. The BEM also allows us to re-use previously computed blocks
of the system matrix."

text: 3D amoeboid cell migration is central to many developmental and disease-related
processes such as cancer metastasis. Here, we identify a unique prototypic amoeboid
cell migration mode in early zebrafish embryos, termed stable-bleb migration.
Stable-bleb cells display an invariant polarized balloon-like shape with exceptional
migration speed and persistence. Progenitor cells can be reversibly transformed
into stable-bleb cells irrespective of their primary fate and motile characteristics
by increasing myosin II activity through biochemical or mechanical stimuli. Using
a combination of theory and experiments, we show that, in stable-bleb cells, cortical
contractility fluctuations trigger a stochastic switch into amoeboid motility,
and a positive feedback between cortical flows and gradients in contractility
maintains stable-bleb cell polarization. We further show that rearward cortical
flows drive stable-bleb cell migration in various adhesive and non-adhesive environments,
unraveling a highly versatile amoeboid migration phenotype.

text: Auxin participates in a multitude of developmental processes, as well as responses
to environmental cues. Compared with other plant hormones, auxin exhibits a unique
property, as it undergoes directional, cell-to-cell transport facilitated by plasma
membrane-localized transport proteins. Among them, a prominent role has been ascribed
to the PIN family of auxin efflux facilitators. PIN proteins direct polar auxin
transport on account of their asymmetric subcellular localizations. In this review,
we provide an overview of the multiple developmental roles of PIN proteins, including
the atypical endoplasmic reticulum-localized members of the family, and look at
the family from an evolutionary perspective. Next, we cover the cell biological
and molecular aspects of PIN function, in particular the establishment of their
polar subcellular localization. Hormonal and environmental inputs into the regulation
of PIN action are summarized as well.
