text: We show that weak solutions of the Derrida-Lebowitz-Speer-Spohn (DLSS) equation
display infinite speed of support propagation. We apply our method to the case
of the quantum drift-diffusion equation which augments the DLSS equation with
a drift term and possibly a second-order diffusion term. The proof is accomplished
using weighted entropy estimates, Hardy's inequality and a family of singular
weight functions to derive a differential inequality; the differential inequality
shows exponential growth of the weighted entropy, with the growth constant blowing
up very fast as the singularity of the weight becomes sharper. To the best of
our knowledge, this is the first example of a nonnegativity-preserving higher-order
parabolic equation displaying infinite speed of support propagation.

text: We derive upper bounds on the waiting time of solutions to the thin-film equation
in the regime of weak slippage n ∈ [2, 32\11). In particular, we give sufficient
conditions on the initial data for instantaneous forward motion of the free boundary.
For n ∈ (2, 32\11), our estimates are sharp, for n = 2, they are sharp up to a
logarithmic correction term. Note that the case n = 2 corresponds-with a grain
of salt-to the assumption of the Navier slip condition at the fluid-solid interface.
We also obtain results in the regime of strong slippage n ∈ (1,2); however, in
this regime we expect them not to be optimal. Our method is based on weighted
backward entropy estimates, Hardy's inequality and singular weight functions;
we deduce a differential inequality which would enforce blowup of the weighted
entropy if the contact line were to remain stationary for too long.

text: Nature has long inspired scientists with its seemingly unlimited ability to
harness solar energy and to utilize it to drive various physiological processes.
With the help of man-made molecular photoswitches, we now have the potential to
outperform natural systems in many ways, with the ultimate goal of fabricating
multifunctional materials that operate at different light wavelengths. An important
challenge in developing light-controlled artificial molecular machines lies in
attaining a detailed understanding of the photoisomerization-coupled conformational
changes that occur in macromolecules and molecular assemblies. In this issue of
ACS Nano, Bléger, Rabe, and co-workers use force microscopy to provide interesting
insights into the behavior of individual photoresponsive molecules and to identify
contraction, extension, and crawling events accompanying light-induced isomerization.

text: Organizing inorganic nanocrystals into complex architectures is challenging
and typically relies on preexisting templates, such as properly folded DNA or
polypeptide chains. We found that under carefully controlled conditions, cubic
nanocrystals of magnetite self-assemble into arrays of helical superstructures
in a template-free manner with >99% yield. Computer simulations revealed that
the formation of helices is determined by the interplay of van der Waals and magnetic
dipole-dipole interactions, Zeeman coupling, and entropic forces and can be attributed
to spontaneous formation of chiral nanocube clusters. Neighboring helices within
their densely packed ensembles tended to adopt the same handedness in order to
maximize packing, thus revealing a novel mechanism of symmetry breaking and chirality
amplification.

text: A compound combining the features of a molecular rotor and a photoswitch was
synthesized and was shown to exist as three diastereomers, which interconvert
via a reversible cyclic reaction scheme. Each of the three diastereomers was isolated,
and by following the equilibration kinetics, activation barriers for all reactions
were calculated. The results indicate that the properties of molecular switches
depend heavily on their immediate chemical environment. The conclusions are important
in the context of designing new switchable molecules and materials.

text: Nanoporous frameworks are polymeric materials built from rigid molecules,
which give rise to their nanoporous structures with applications in gas sorption
and storage, catalysis and others. Conceptually new applications could emerge,
should these beneficial properties be manipulated by external stimuli in a reversible
manner. One approach to render nanoporous frameworks responsive to external signals
would be to immobilize molecular switches within their nanopores. Although the
majority of molecular switches require conformational freedom to isomerize, and
switching in the solid state is prohibited, the nanopores may provide enough room
for the switches to efficiently isomerize. Here we describe two families of nanoporous
materials incorporating the spiropyran molecular switch. These materials exhibit
a variety of interesting properties, including reversible photochromism and acidochromism
under solvent-free conditions, light-controlled capture and release of metal ions,
as well reversible chromism induced by solvation/desolvation.

text: In the past few years, spiropyran has emerged as the molecule-of-choice for
the construction of novel dynamic materials. This unique molecular switch undergoes
structural isomerisation in response to a variety of orthogonal stimuli, e.g.
light, temperature, metal ions, redox potential, and mechanical stress. Incorporation
of this switch onto macromolecular supports or inorganic scaffolds allows for
the creation of robust dynamic materials. This review discusses the synthesis,
switching conditions, and use of dynamic materials in which spiropyran has been
attached to the surfaces of polymers, biomacromolecules, inorganic nanoparticles,
as well as solid surfaces. The resulting materials show fascinating properties
whereby the state of the switch intimately affects a multitude of useful properties
of the support. The utility of the spiropyran switch will undoubtedly endow these
materials with far-reaching applications in the near future.

text: 'We consider directed graphs where each edge is labeled with an integer weight
and study the fundamental algorithmic question of computing the value of a cycle
with minimum mean weight. Our contributions are twofold: (1) First we show that
the algorithmic question is reducible to the problem of a logarithmic number of
min-plus matrix multiplications of n×n-matrices, where n is the number of vertices
of the graph. (2) Second, when the weights are nonnegative, we present the first
(1+ε)-approximation algorithm for the problem and the running time of our algorithm
is Õ(nωlog3(nW/ε)/ε),1 where O(nω) is the time required for the classic n×n-matrix
multiplication and W is the maximum value of the weights. With an additional O(log(nW/ε))
factor in space a cycle with approximately optimal weight can be computed within
the same time bound.'

text: Fault-tolerant distributed algorithms play an important role in ensuring the
reliability of many software applications. In this paper we consider distributed
algorithms whose computations are organized in rounds. To verify the correctness
of such algorithms, we reason about (i) properties (such as invariants) of the
state, (ii) the transitions controlled by the algorithm, and (iii) the communication
graph. We introduce a logic that addresses these points, and contains set comprehensions
with cardinality constraints, function symbols to describe the local states of
each process, and a limited form of quantifier alternation to express the verification
conditions. We show its use in automating the verification of consensus algorithms.
In particular, we give a semi-decision procedure for the unsatisfiability problem
of the logic and identify a decidable fragment. We successfully applied our framework
to verify the correctness of a variety of consensus algorithms tolerant to both
benign faults (message loss, process crashes) and value faults (message corruption).

text: 'Probabilistic programs are usual functional or imperative programs with two
added constructs: (1) the ability to draw values at random from distributions,
and (2) the ability to condition values of variables in a program via observations.
Models from diverse application areas such as computer vision, coding theory,
cryptographic protocols, biology and reliability analysis can be written as probabilistic
programs. Probabilistic inference is the problem of computing an explicit representation
of the probability distribution implicitly specified by a probabilistic program.
Depending on the application, the desired output from inference may vary-we may
want to estimate the expected value of some function f with respect to the distribution,
or the mode of the distribution, or simply a set of samples drawn from the distribution.
In this paper, we describe connections this research area called \Probabilistic
Programming" has with programming languages and software engineering, and
this includes language design, and the static and dynamic analysis of programs.
We survey current state of the art and speculate on promising directions for future
research.'

by the invasive garden ant Lasius neglectus mostly against entomopathogenic fungi. The
first two chapters of this thesis address the phenomenon of 'social immunisation'.
Social immunisation, that is the immunological protection of group members due
to social contact to a pathogen-exposed nestmate, has been described in various
social insect species against different types of pathogens. However, in the case
of entomopathogenic fungi it has, so far, only been demonstrated that social immunisation
exists at all. Its underlying mechanisms r any other properties were, however,
unknown. In the first chapter of this thesis I identified the mechanistic basis
of social immunisation in L. neglectus against the entomopathogenous fungus Metarhizium.
I could show that nestmates of a pathogen-exposed individual contract low-level
infections due to social interactions. These low-level infections are, however,
non-lethal and cause an active stimulation of the immune system, which protects
the nestmates upon subsequent pathogen encounters. In the second chapter of this
thesis I investigated the specificity and colony level effects of social immunisation.
I demonstrated that the protection conferred by social immunisation is highly
specific, protecting ants only against the same pathogen strain. In addition,
depending on the respective context, social immunisation may even cause fitness
costs. I further showed that social immunisation crucially affects sanitary behaviour
and disease dynamics within ant groups. In the third chapter of this thesis I
studied the effects of the ectosymbiotic fungus Laboulbenia formicarum on its
host L. neglectus. Although Laboulbeniales are the largest order of insect-parasitic
fungi, research concerning host fitness consequence is sparse. I showed that highly
Laboulbenia-infected ants sustain fitness costs under resource limitation, however,
gain fitness benefits when exposed to an entomopathogenus fungus. These effects
are probably cause by a prophylactic upregulation of behavioural as well as physiological
immune defences in highly infected ants.

text: The sensitivities of high-harmonic generation (HHG) and strong-field ionization
(SFI) to coupled electronic and nuclear dynamics are studied, using the nitric
oxide (NO) molecule as an example. A coherent superposition of electronic and
rotational states of NO is prepared by impulsive stimulated Raman scattering and
probed by simultaneous detection of HHG and SFI yields. We observe a fourfold
higher sensitivity of high-harmonic generation to electronic dynamics and attribute
it to the presence of inelastic quantum paths connecting coherently related electronic
states [Kraus et al., Phys. Rev. Lett.111, 243005 (2013)]. Whereas different harmonic
orders display very different sensitivities to rotational or electronic dynamics,
strong-field ionization is found to be most sensitive to electronic motion. We
introduce a general theoretical formalism for high-harmonic generation from coupled
nuclear-electronic wave packets. We show that the unequal sensitivities of different
harmonic orders to electronic or rotational dynamics result from the angle dependence
of the photorecombination matrix elements which encode several autoionizing and
shape resonances in the photoionization continuum of NO. We further study the
dependence of rotational and electronic coherences on the intensity of the excitation
pulse and support the observations with calculations.

text: The cyclopropene radical cation (c-C3H₄⁺) is an important but poorly characterized
three-membered-ring hydrocarbon. We report on a measurement of the high-resolution
photoelectron and photoionization spectra of cyclopropene and several deuterated
isotopomers, from which we have determined the rovibrational energy level structure
of the X⁺ (2)B2 ground electronic state of c-C3H₄⁺ at low energies for the first
time. The synthesis of the partially deuterated isotopomers always resulted in
mixtures of several isotopomers, differing in their number of D atoms and in the
location of these atoms, so that the photoelectron spectra of deuterated samples
are superpositions of the spectra of several isotopomers. The rotationally resolved
spectra indicate a C(2v)-symmetric R0 structure for the ground electronic state
of c-C3H₄⁺. Two vibrational modes of c-C3H₄⁺ are found to have vibrational wave
numbers below 300 cm(-1), which is surprising for such a small cyclic hydrocarbon.
The analysis of the isotopic shifts of the vibrational levels enabled the assignment
of the lowest-frequency mode (fundamental wave number of ≈110 cm(-1) in c-C3H₄⁺)
to the CH2 torsional mode (ν₈⁺, A2 symmetry) and of the second-lowest-frequency
mode (≈210 cm(-1) in c-C3H₄⁺) to a mode combining a CH out-of-plane with a CH2
rocking motion (ν₁₅⁺, B2 symmetry). The potential energy along the CH2 torsional
coordinate is flat near the equilibrium structure and leads to a pronounced anharmonicity.

text: Phosphatidylinositol (Ptdlns) is a structural phospholipid that can be phosphorylated
into various lipid signaling molecules, designated polyphosphoinositides (PPIs).
The reversible phosphorylation of PPIs on the 3, 4, or 5 position of inositol
is performed by a set of organelle-specific kinases and phosphatases, and the
characteristic head groups make these molecules ideal for regulating biological
processes in time and space. In yeast and mammals, Ptdlns3P and Ptdlns(3,5)P2
play crucial roles in trafficking toward the lytic compartments, whereas the role
in plants is not yet fully understood. Here we identified the role of a land plant-specific
subgroup of PPI phosphatases, the suppressor of actin 2 (SAC2) to SAC5, during
vauolar trafficking and morphogenesis in Arabidopsis thaliana. SAC2-SAC5 localize
to the tonoplast along with Ptdlns3P, the presumable product of their activity.
in SAC gain- and loss-of-function mutants, the levels of Ptdlns monophosphates
and bisphosphates were changed, with opposite effects on the morphology of storage
and lytic vacuoles, and the trafficking toward the vacuoles was defective. Moreover,
multiple sac knockout mutants had an increased number of smaller storage and lytic
vacuoles, whereas extralarge vacuoles were observed in the overexpression lines,
correlating with various growth and developmental defects. The fragmented vacuolar
phenotype of sac mutants could be mimicked by treating wild-type seedlings with
Ptdlns(3,5)P2, corroborating that this PPI is important for vacuole morphology.
Taken together, these results provide evidence that PPIs, together with their
metabolic enzymes SAC2-SAC5, are crucial for vacuolar trafficking and for vacuolar
morphology and function in plants.

text: We report the observation of macroscopic field-free orientation, i.e., more
than 73% of CO molecules pointing in the same direction. This is achieved through
an all-optical scheme operating at high particle densities (>10(17) cm(-3)) that
combines one-color (ω) and two-color (ω+2ω) nonresonant femtosecond laser pulses.
We show that the achieved orientation solely relies on the hyperpolarizability
interaction as opposed to an ionization-depletion mechanism, thus, opening a wide
range of applications. The achieved strong orientation enables us to reveal the
molecular-frame anisotropies of the photorecombination amplitudes and phases caused
by a shape resonance. The resonance appears as a local maximum in the even-harmonic
emission around 28 eV. In contrast, the odd-harmonic emission is suppressed in
this spectral region through the combined effects of an asymmetric photorecombination
phase and a subcycle Stark effect, generic for polar molecules, that we experimentally
identify.

text: We present the detailed analysis of a new two-pulse orientation scheme that
achieves macroscopic field-free orientation at the high particle densities required
for attosecond and high-harmonic spectroscopies (Kraus et al 2013 arXiv:1311.3923).
Carbon monoxide molecules are oriented by combining one-colour and delayed two-colour
non-resonant femtosecond laser pulses. High-harmonic generation is used to probe
the oriented wave-packet dynamics and reveals that a very high degree of orientation
(Nup/Ntotal = 0.73–0.82) is achieved. We further extend this approach to orienting
carbonyl sulphide molecules. We show that the present two-pulse scheme selectively
enhances orientation created by the hyperpolarizability interaction whereas the
ionization-depletion mechanism plays no role. We further control and optimize
orientation through the delay between the one- and two-colour pump pulses. Finally,
we demonstrate a complementary encoding of electronic-structure features, such
as shape resonances, in the even- and odd-harmonic spectrum. The achieved progress
makes two-pulse field-free orientation an attractive tool for a broad class of
time-resolved measurements.

text: A variety of developmental and disease related processes depend on epithelial
cell sheet spreading. In order to gain insight into the biophysical mechanism(s)
underlying the tissue morphogenesis we studied the spreading of an epithelium
during the early development of the zebrafish embryo. In zebrafish epiboly the
enveloping cell layer (EVL), a simple squamous epithelium, spreads over the yolk
cell to completely engulf it at the end of gastrulation. Previous studies have
proposed that an actomyosin ring forming within the yolk syncytial layer (YSL)
acts as purse string that through constriction along its circumference pulls on
the margin of the EVL. Direct biophysical evidence for this hypothesis has however
been missing. The aim of the thesis was to understand how the actomyosin ring
may generate pulling forces onto the EVL and what cellular mechanism(s) may facilitate
the spreading of the epithelium. Using laser ablation to measure cortical tension
within the actomyosin ring we found an anisotropic tension distribution, which
was highest along the circumference of the ring. However the low degree of anisotropy
was incompatible with the actomyosin ring functioning as a purse string only.
Additionally, we observed retrograde cortical flow from vegetal parts of the ring
into the EVL margin. Interpreting the experimental data using a theoretical distribution
that models the tissues as active viscous gels led us to proposen that the actomyosin
ring has a twofold contribution to EVL epiboly. It not only acts as a purse string
through constriction along its circumference, but in addition constriction along
the width of the ring generates pulling forces through friction-resisted cortical
flow. Moreover, when rendering the purse string mechanism unproductive EVL epiboly
proceeded normally indicating that the flow-friction mechanism is sufficient to
drive the process. Aiming to understand what cellular mechanism(s) may facilitate
the spreading of the epithelium we found that tension-oriented EVL cell divisions
limit tissue anisotropy by releasing tension along the division axis and promote
epithelial spreading. Notably, EVL cells undergo ectopic cell fusion in conditions
in which oriented-cell division is impaired or the epithelium is mechanically
challenged. Taken together our study of EVL epiboly suggests a novel mechanism
of force generation for actomyosin rings through friction-resisted cortical flow
and highlights the importance of tension-oriented cell divisions in epithelial
morphogenesis.

text: "The co-evolution of hosts and pathogens is characterized by continuous adaptations
of both parties. Pathogens of social insects need to adapt towards disease defences
at two levels: 1) individual immunity of each colony member consisting of behavioural
defence strategies as well as humoral and cellular immune responses and 2) social
immunity that is collectively performed by all group members comprising behavioural,
physiological and organisational defence strategies.\r\n\r\nTo disentangle the
selection pressure on pathogens by the collective versus individual level of disease
defence in social insects, we performed an evolution experiment using the Argentine
Ant, Linepithema humile, as a host and a mixture of the general insect pathogenic
fungus Metarhizium spp. (6 strains) as a pathogen. We allowed pathogen evolution
over 10 serial host passages to two different evolution host treatments: (1) only
individual host immunity in a single host treatment, and (2) simultaneously acting
individual and social immunity in a social host treatment, in which an exposed
ant was accompanied by two untreated nestmates.\r\n\r\nBefore starting the pathogen
evolution experiment, the 6 Metarhizium spp. strains were characterised concerning
conidiospore size killing rates in singly and socially reared ants, their competitiveness
under coinfecting conditions and their influence on ant behaviour. We analysed
how the ancestral atrain mixture changed in conidiospere size, killing rate and
strain composition dependent on host treatment (single or social hosts) during
10 passages and found that killing rate and conidiospere size of the pathogen
increased under both evolution regimes, but different depending on host treatment.\r\n\r\nTesting
the evolved strain mixtures that evolved under either the single or social host
treatment under both single and social current rearing conditions in a full factorial
design experiment revealed that the additional collective defences in insect societies
add new selection pressure for their coevolving pathogens that compromise their
ability to adapt to its host at the group level. To our knowledge, this is the
first study directly measuring the influence of social immunity on pathogen evolution."
