text: 'The existence of a self-localization transition in the polaron problem has
been under an active debate ever since Landau suggested it 83 years ago. Here
we reveal the self-localization transition for the rotational analogue of the
polaron -- the angulon quasiparticle. We show that, unlike for the polarons, self-localization
of angulons occurs at finite impurity-bath coupling already at the mean-field
level. The transition is accompanied by the spherical-symmetry breaking of the
angulon ground state and a discontinuity in the first derivative of the ground-state
energy. Moreover, the type of the symmetry breaking is dictated by the symmetry
of the microscopic impurity-bath interaction, which leads to a number of distinct
self-localized states. The predicted effects can potentially be addressed in experiments
on cold molecules trapped in superfluid helium droplets and ultracold quantum
gases, as well as on electronic excitations in solids and Bose-Einstein condensates. '

text: "Plant hormone auxin and its transport between cells belong to the most important\r\nmechanisms
controlling plant development. Auxin itself could change localization of PINs
and\r\nthereby control direction of its own flow. We performed an expression profiling
experiment\r\nin Arabidopsis roots to identify potential regulators of PIN polarity
which are transcriptionally\r\nregulated by auxin signalling. We identified several
novel regulators and performed a detailed\r\ncharacterization of the transcription
factor WRKY23 (At2g47260) and its role in auxin\r\nfeedback on PIN polarity. Gain-of-function
and dominant-negative mutants revealed that\r\nWRKY23 plays a crucial role in
mediating the auxin effect on PIN polarity. In concordance,\r\ntypical polar auxin
transport processes such as gravitropism and leaf vascular pattern\r\nformation
were disturbed by interfering with WRKY23 function.\r\nIn order to identify direct
targets of WRKY23, we performed consequential expression\r\nprofiling experiments
using a WRKY23 inducible gain-of-function line and dominant-negative\r\nWRKY23
line that is defunct in PIN re-arrangement. Among several genes mostly related
to\r\nthe groups of cell wall and defense process regulators, we identified LYSINE-HISTIDINE\r\nTRANSPORTER
1 (LHT1; At5g40780), a small amino acid permease gene from the amino\r\nacid/auxin
permease family (AAAP), we present its detailed characterisation in auxin feedback\r\non
PIN repolarization, identified its transcriptional regulation, we propose a potential\r\nmechanism
of its action. Moreover, we identified also a member of receptor-like protein\r\nkinase
LRR-RLK (LEUCINE-RICH REPEAT TRANSMEMBRANE PROTEIN KINASE PROTEIN 1;\r\nLRRK1;
At1g05700), which also affects auxin-dependent PIN re-arrangement. We described\r\nits
transcriptional behaviour, subcellular localization. Based on global expression
data, we\r\ntried to identify ligand responsible for mechanism of signalling and
suggest signalling partner\r\nand interactors. Additionally, we described role
of novel phytohormone group, strigolactone,\r\nin auxin-dependent PIN re-arrangement,
that could be a fundament for future studies in this\r\nfield.\r\nOur results
provide first insights into an auxin transcriptional network targeting PIN\r\nlocalization
and thus regulating plant development. We highlighted WRKY23 transcriptional\r\nnetwork
and characterised its mediatory role in plant development. We identified direct\r\neffectors
of this network, LHT1 and LRRK1, and describe their roles in PIN re-arrangement
and\r\nPIN-dependent auxin transport processes."
acknowledgement: I would like to first acknowledge my supervisor Jiří Friml for support,
kind advice and patience. It was a pleasure to be a part of your lab, Jiří. I will
remember the atmosphere present in auxin lab at VIB in Ghent and at IST in Klosterneuburg
forever. I would like to thank all past and present lab members for the friendship
and friendly and scientific environment in the groups. It was so nice to cooperate
with you, guys. There was always someone who helped me with experiments, troubleshoot
issues coming from our work etc. At this place, I would like to thank especially
to Gergo Molnár. I’m happy (and lucky) that I have met him; he naturally became
my tutor and guide through my PhD. From no one else during my entire professional
career, I’ve learned that much.

text: The hippocampus is thought to initiate systems-wide mnemonic processes through
the reactivation of previously acquired spatial and episodic memory traces, which
can recruit the entorhinal cortex as a first stage of memory redistribution to
other brain areas. Hippocampal reactivation occurs during sharp wave-ripples,
in which synchronous network firing encodes sequences of places.We investigated
the coordination of this replay by recording assembly activity simultaneously
in the CA1 region of the hippocampus and superficial layers of the medial entorhinal
cortex. We found that entorhinal cell assemblies can replay trajectories independently
of the hippocampus and sharp wave-ripples. This suggests that the hippocampus
is not the sole initiator of spatial and episodic memory trace reactivation. Memory
systems involved in these processes may include nonhierarchical, parallel components.

text: 'It is a common knowledge that an effective interaction of a quantum impurity
with an electromagnetic field can be screened by surrounding charge carriers,
whether mobile or static. Here we demonstrate that very strong, "anomalous" screening
can take place in the presence of a neutral, weakly polarizable environment, due
to an exchange of orbital angular momentum between the impurity and the bath.
Furthermore, we show that it is possible to generalize all phenomena related to
isolated impurities in an external field to the case when a many-body environment
is present, by casting the problem in terms of the angulon quasiparticle. As a
result, the relevant observables such as the effective Rabi frequency, geometric
phase, and impurity spatial alignment are straightforward to evaluate in terms
of a single parameter: the angular-momentum-dependent screening factor.'

text: We show that matrix elements of functions of N × N Wigner matrices fluctuate
on a scale of order N−1/2 and we identify the limiting fluctuation. Our result
holds for any function f of the matrix that has bounded variation thus considerably
relaxing the regularity requirement imposed in [7, 11].

text: 'Aim: The present study was to compare the effects of nicotinic acid and nicotinamide
on the plasma methyl donors, choline and betaine. Methods: Thirty adult subjects
were randomly divided into three groups of equal size, and orally received purified
water (C group), nicotinic acid (300 mg, NA group) or nicotinamide (300 mg, NM
group). Plasma nicotinamide, N 1-methylnicotinamide, homocysteine, betaine and
choline levels before and 1.5-h and 3-h post-dosing, plasma normetanephrine and
metanephrine concentrations at 3-h post-dosing, and the urinary excretion of N
1-methyl-2-pyridone-5-carboxamide during the test period were examined. Results:
The level of 3-h plasma nicotinamide, N 1-methylnicotinamide, homocysteine, the
urinary excretion of N 1-methyl-2-pyridone-5-carboxamide and pulse pressure (PP)
in the NM group was 221%, 3972%, 61%, 1728% and 21.2% higher than that of the
control group (P < 0.01, except homocysteine and PP P < 0.05), while the
3-h plasma betaine, normetanephrine and metanephrine level in the NM group was
24.4%, 9.4% and 11.7% lower (P < 0.05, except betaine P < 0.01), without
significant difference in choline levels. Similar but less pronounced changes
were observed in the NA group, with a lower level of 3-h plasma N 1-methylnicotinamide
(1.90 ± 0.20 μmol/l vs. 3.62 ± 0.27 μmol/l, P < 0.01) and homocysteine (12.85
± 1.39 μmol/l vs. 18.08 ± 1.02 μmol/l, P < 0.05) but a higher level of betaine
(27.44 ± 0.71 μmol/l vs. 23.52 ± 0.61 μmol/l, P < 0.05) than that of the NM
group. Conclusion: The degradation of nicotinamide consumes more betaine than
that of nicotinic acid at identical doses. This difference should be taken into
consideration in niacin fortification. © 2016 Elsevier Ltd and European Society

text: We propose a new memetic strategy that can solve the multi-physics, complex
inverse problems, formulated as the multi-objective optimization ones, in which
objectives are misfits between the measured and simulated states of various governing
processes. The multi-deme structure of the strategy allows for both, intensive,
relatively cheap exploration with a moderate accuracy and more accurate search
many regions of Pareto set in parallel. The special type of selection operator
prefers the coherent alternative solutions, eliminating artifacts appearing in
the particular processes. The additional accuracy increment is obtained by the
parallel convex searches applied to the local scalarizations of the misfit vector.
The strategy is dedicated for solving ill-conditioned problems, for which inverting
the single physical process can lead to the ambiguous results. The skill of the
selection in artifact elimination is shown on the benchmark problem, while the
whole strategy was applied for identification of oil deposits, where the misfits
are related to various frequencies of the magnetic and electric waves of the magnetotelluric
measurements. 2016 Elsevier B.V.

text: This dissertation concerns the automatic verification of probabilistic systems
and programs with arrays by statistical and logical methods. Although statistical
and logical methods are different in nature, we show that they can be successfully
combined for system analysis. In the first part of the dissertation we present
a new statistical algorithm for the verification of probabilistic systems with
respect to unbounded properties, including linear temporal logic. Our algorithm
often performs faster than the previous approaches, and at the same time requires
less information about the system. In addition, our method can be generalized
to unbounded quantitative properties such as mean-payoff bounds. In the second
part, we introduce two techniques for comparing probabilistic systems. Probabilistic
systems are typically compared using the notion of equivalence, which requires
the systems to have the equal probability of all behaviors. However, this notion
is often too strict, since probabilities are typically only empirically estimated,
and any imprecision may break the relation between processes. On the one hand,
we propose to replace the Boolean notion of equivalence by a quantitative distance
of similarity. For this purpose, we introduce a statistical framework for estimating
distances between Markov chains based on their simulation runs, and we investigate
which distances can be approximated in our framework. On the other hand, we propose
to compare systems with respect to a new qualitative logic, which expresses that
behaviors occur with probability one or a positive probability. This qualitative
analysis is robust with respect to modeling errors and applicable to many domains.
In the last part, we present a new quantifier-free logic for integer arrays, which
allows us to express counting. Counting properties are prevalent in array-manipulating
programs, however they cannot be expressed in the quantified fragments of the
theory of arrays. We present a decision procedure for our logic, and provide several
complexity results.

text: Auxin steers numerous physiological processes in plants, making the tight
control of its endogenous levels and spatiotemporal distribution a necessity.
This regulation is achieved by different mechanisms, including auxin biosynthesis,
metabolic conversions, degradation, and transport. Here, we introduce cis-cinnamic
acid (c-CA) as a novel and unique addition to a small group of endogenous molecules
affecting in planta auxin concentrations. c-CA is the photo-isomerization product
of the phenylpropanoid pathway intermediate trans-CA (t-CA). When grown on c-CA-containing
medium, an evolutionary diverse set of plant species were shown to exhibit phenotypes
characteristic for high auxin levels, including inhibition of primary root growth,
induction of root hairs, and promotion of adventitious and lateral rooting. By
molecular docking and receptor binding assays, we showed that c-CA itself is neither
an auxin nor an anti-auxin, and auxin profiling data revealed that c-CA does not
significantly interfere with auxin biosynthesis. Single cell-based auxin accumulation
assays showed that c-CA, and not t-CA, is a potent inhibitor of auxin efflux.
Auxin signaling reporters detected changes in spatiotemporal distribution of the
auxin response along the root of c-CA-treated plants, and long-distance auxin
transport assays showed no inhibition of rootward auxin transport. Overall, these
results suggest that the phenotypes of c-CA-treated plants are the consequence
of a local change in auxin accumulation, induced by the inhibition of auxin efflux.
This work reveals a novel mechanism how plants may regulate auxin levels and adds
a novel, naturally occurring molecule to the chemical toolbox for the studies
of auxin homeostasis.

text: 'We investigate fundamental nonlinear dynamics of ferrofluidic Taylor-Couette
flow - flow confined be-tween two concentric independently rotating cylinders
- consider small aspect ratio by solving the ferro-hydrodynamical equations, carrying
out systematic bifurcation analysis. Without magnetic field, we find steady flow
patterns, previously observed with a simple fluid, such as those containing normal
one- or two vortex cells, as well as anomalous one-cell and twin-cell flow states.
However, when a symmetry-breaking transverse magnetic field is present, all flow
states exhibit stimulated, finite two-fold mode. Various bifurcations between
steady and unsteady states can occur, corresponding to the transitions between
the two-cell and one-cell states. While unsteady, axially oscillating flow states
can arise, we also detect the emergence of new unsteady flow states. In particular,
we uncover two new states: one contains only the azimuthally oscillating solution
in the configuration of the twin-cell flow state, and an-other a rotating flow
state. Topologically, these flow states are a limit cycle and a quasiperiodic
solution on a two-torus, respectively. Emergence of new flow states in addition
to observed ones with classical fluid, indicates that richer but potentially more
controllable dynamics in ferrofluidic flows, as such flow states depend on the
external magnetic field.'

text: Coordinated changes of cell shape are often the result of the excitable, wave-like

waves arise from mechanochemical crosstalk between adhesion sites, membrane tension
and the actin protrusive machinery.

text: Selected universal experimental properties of high-temperature superconducting
(HTS) cuprates have been singled out in the last decade. One of the pivotal challenges
in this field is the designation of a consistent interpretation framework within
which we can describe quantitatively the universal features of those systems.
Here we analyze in a detailed manner the principal experimental data and compare
them quantitatively with the approach based on a single-band model of strongly
correlated electrons supplemented with strong antiferromagnetic (super)exchange
interaction (the so-called t−J−U model). The model rationale is provided by estimating
its microscopic parameters on the basis of the three-band approach for the Cu-O
plane. We use our original full Gutzwiller wave-function solution by going beyond
the renormalized mean-field theory (RMFT) in a systematic manner. Our approach
reproduces very well the observed hole doping (δ) dependence of the kinetic-energy
gain in the superconducting phase, one of the principal non-Bardeen-Cooper-Schrieffer
features of the cuprates. The calculated Fermi velocity in the nodal direction
is practically δ-independent and its universal value agrees very well with that
determined experimentally. Also, a weak doping dependence of the Fermi wave vector
leads to an almost constant value of the effective mass in a pure superconducting
phase which is both observed in experiment and reproduced within our approach.
An assessment of the currently used models (t−J, Hubbard) is carried out and the
results of the canonical RMFT as a zeroth-order solution are provided for comparison
to illustrate the necessity of the introduced higher-order contributions.

text: 'We investigate the effect of the electron-hole (e-h) symmetry breaking on
d-wave superconductivity induced by non-local effects of correlations in the generalized
Hubbard model. The symmetry breaking is introduced in a two-fold manner: by the
next-to-nearest neighbor hopping of electrons and by the charge-bond interaction
- the off-diagonal term of the Coulomb potential. Both terms lead to a pronounced
asymmetry of the superconducting order parameter. The next-to-nearest neighbor
hopping enhances superconductivity for h-doping, while diminishes it for e-doping.
The charge-bond interaction alone leads to the opposite effect and, additionally,
to the kinetic-energy gain upon condensation in the underdoped regime. With both
terms included, with similar amplitudes, the height of the superconducting dome
and the critical doping remain in favor of h-doping. The influence of the charge-bond
interaction on deviations from symmetry of the shape of the gap at the Fermi surface
in the momentum space is briefly discussed.'

text: Optimum experimental design theory has recently been extended for parameter
estimation in copula models. The use of these models allows one to gain in flexibility
by considering the model parameter set split into marginal and dependence parameters.
However, this separation also leads to the natural issue of estimating only a
subset of all model parameters. In this work, we treat this problem with the application
of the (Formula presented.)-optimality to copula models. First, we provide an
extension of the corresponding equivalence theory. Then, we analyze a wide range
of flexible copula models to highlight the usefulness of (Formula presented.)-optimality
in many possible scenarios. Finally, we discuss how the usage of the introduced
design criterion also relates to the more general issue of copula selection and
optimal design for model discrimination.

text: Dispersal is a crucial factor in natural evolution, since it determines the
habitat experienced by any population and defines the spatial scale of interactions
between individuals. There is compelling evidence for systematic differences in
dispersal characteristics within the same population, i.e., genotype-dependent
dispersal. The consequences of genotype-dependent dispersal on other evolutionary
phenomena, however, are poorly understood. In this article we investigate the
effect of genotype-dependent dispersal on spatial gene frequency patterns, using
a generalization of the classical diffusion model of selection and dispersal.
Dispersal is characterized by the variance of dispersal (diffusion coefficient)
and the mean displacement (directional advection term). We demonstrate that genotype-dependent
dispersal may change the qualitative behavior of Fisher waves, which change from
being “pulled” to being “pushed” wave fronts as the discrepancy in dispersal between
genotypes increases. The speed of any wave is partitioned into components due
to selection, genotype-dependent variance of dispersal, and genotype-dependent
mean displacement. We apply our findings to wave fronts maintained by selection
against heterozygotes. Furthermore, we identify a benefit of increased variance
of dispersal, quantify its effect on the speed of the wave, and discuss the implications
for the evolution of dispersal strategies.

text: Security of cryptographic applications is typically defined by security games.
The adversary, within certain resources, cannot win with probability much better
than 0 (for unpredictability applications, like one-way functions) or much better
than 1/2 (indistinguishability applications for instance encryption schemes).
In so called squared-friendly applications the winning probability of the adversary,
for different values of the application secret randomness, is not only close to
0 or 1/2 on average, but also concentrated in the sense that its second central
moment is small. The class of squared-friendly applications, which contains all
unpredictability applications and many indistinguishability applications, is particularly
important for key derivation. Barak et al. observed that for square-friendly applications
one can beat the "RT-bound", extracting secure keys with significantly
smaller entropy loss. In turn Dodis and Yu showed that in squared-friendly applications
one can directly use a "weak" key, which has only high entropy, as a
secure key. In this paper we give sharp lower bounds on square security assuming
security for "weak" keys. We show that any application which is either
(a) secure with weak keys or (b) allows for entropy savings for keys derived by
universal hashing, must be square-friendly. Quantitatively, our lower bounds match
the positive results of Dodis and Yu and Barak et al. (TCC\'13, CRYPTO\'11) Hence,
they can be understood as a general characterization of squared-friendly applications.
While the positive results on squared-friendly applications where derived by one
clever application of the Cauchy-Schwarz Inequality, for tight lower bounds we
need more machinery. In our approach we use convex optimization techniques and
some theory of circular matrices.

text: We study space complexity and time-space trade-offs with a focus not on peak
memory usage but on overall memory consumption throughout the computation. Such
a cumulative space measure was introduced for the computational model of parallel
black pebbling by [Alwen and Serbinenko ’15] as a tool for obtaining results in
cryptography. We consider instead the non- deterministic black-white pebble game
and prove optimal cumulative space lower bounds and trade-offs, where in order
to minimize pebbling time the space has to remain large during a significant fraction
of the pebbling. We also initiate the study of cumulative space in proof complexity,
an area where other space complexity measures have been extensively studied during
the last 10–15 years. Using and extending the connection between proof complexity
and pebble games in [Ben-Sasson and Nordström ’08, ’11] we obtain several strong
cumulative space results for (even parallel versions of) the resolution proof
system, and outline some possible future directions of study of this, in our opinion,
natural and interesting space measure.

text: The algorithm Argon2i-B of Biryukov, Dinu and Khovratovich is currently being
considered by the IRTF (Internet Research Task Force) as a new de-facto standard
for password hashing. An older version (Argon2i-A) of the same algorithm was chosen
as the winner of the recent Password Hashing Competition. An important competitor
to Argon2i-B is the recently introduced Balloon Hashing (BH) algorithm of Corrigan-Gibs,
Boneh and Schechter. A key security desiderata for any such algorithm is that
evaluating it (even using a custom device) requires a large amount of memory amortized
across multiple instances. Alwen and Blocki (CRYPTO 2016) introduced a class of
theoretical attacks against Argon2i-A and BH. While these attacks yield large
asymptotic reductions in the amount of memory, it was not, a priori, clear if
(1) they can be extended to the newer Argon2i-B, (2) the attacks are effective
on any algorithm for practical parameter ranges (e.g., 1GB of memory) and (3)
if they can be effectively instantiated against any algorithm under realistic
hardware constrains. In this work we answer all three of these questions in the
affirmative for all three algorithms. This is also the first work to analyze the
security of Argon2i-B. In more detail, we extend the theoretical attacks of Alwen
and Blocki (CRYPTO 2016) to the recent Argon2i-B proposal demonstrating severe
asymptotic deficiencies in its security. Next we introduce several novel heuristics
for improving the attack's concrete memory efficiency even when on-chip memory
bandwidth is bounded. We then simulate our attacks on randomly sampled Argon2i-A,
Argon2i-B and BH instances and measure the resulting memory consumption for various
practical parameter ranges and for a variety of upperbounds on the amount of parallelism
available to the attacker. Finally we describe, implement, and test a new heuristic
for applying the Alwen-Blocki attack to functions employing a technique developed
by Corrigan-Gibs et al. for improving concrete security of memory-hard functions.
We analyze the collected data and show the effects various parameters have on
the memory consumption of the attack. In particular, we can draw several interesting
conclusions about the level of security provided by these functions. · For the
Alwen-Blocki attack to fail against practical memory parameters, Argon2i-B must
be instantiated with more than 10 passes on memory - beyond the "paranoid" parameter
setting in the current IRTF proposal. · The technique of Corrigan-Gibs for improving
security can also be overcome by the Alwen-Blocki attack under realistic hardware
constraints. · On a positive note, both the asymptotic and concrete security of
Argon2i-B seem to improve on that of Argon2i-A.

text: 'Consider the following random process: we are given n queues, into which
elements of increasing labels are inserted uniformly at random. To remove an element,
we pick two queues at random, and remove the element of lower label (higher priority)
among the two. The cost of a removal is the rank of the label removed, among labels
still present in any of the queues, that is, the distance from the optimal choice
at each step. Variants of this strategy are prevalent in state-of-the-art concurrent
priority queue implementations. Nonetheless, it is not known whether such implementations
provide any rank guarantees, even in a sequential model. We answer this question,
showing that this strategy provides surprisingly strong guarantees: Although the
single-choice process, where we always insert and remove from a single randomly
chosen queue, has degrading cost, going to infinity as we increase the number
of steps, in the two choice process, the expected rank of a removed element is
O(n) while the expected worst-case cost is O(n log n). These bounds are tight,
and hold irrespective of the number of steps for which we run the process. The
argument is based on a new technical connection between "heavily loaded"
balls-into-bins processes and priority scheduling. Our analytic results inspire
a new concurrent priority queue implementation, which improves upon the state
of the art in terms of practical performance.'
