text: We study the problem of specifying sequential information-flow properties
of systems. Information-flow properties are hyperproperties, as they compare different
traces of a system. Sequential information-flow properties can express changes,
over time, in the information-flow constraints. For example, information-flow
constraints during an initialization phase of a system may be different from information-flow
constraints that are required during the operation phase. We formalize several
variants of interpreting sequential information-flow constraints, which arise
from different assumptions about what can be observed of the system. For this
purpose, we introduce a first-order logic, called Hypertrace Logic, with both
trace and time quantifiers for specifying linear-time hyperproperties. We prove
that HyperLTL, which corresponds to a fragment of Hypertrace Logic with restricted
quantifier prefixes, cannot specify the majority of the studied variants of sequential
information flow, including all variants in which the transition between sequential
phases (such as initialization and operation) happens asynchronously. Our results
rely on new equivalences between sets of traces that cannot be distinguished by
certain classes of formulas from Hypertrace Logic. This presents a new approach
to proving inexpressiveness results for HyperLTL.

text: A matching is compatible to two or more labeled point sets of size n with
labels {1, . . . , n} if its straight-line drawing on each of these point sets
is crossing-free. We study the maximum number of edges in a matching compatible
to two or more labeled point sets in general position in the plane. We show that
for any two labeled sets of n points in convex position there exists a compatible
matching with ⌊√2n + 1 − 1⌋ edges. More generally, for any ℓ labeled point sets
we construct compatible matchings of size Ω(n1/ℓ). As a corresponding upper bound,
we use probabilistic arguments to show that for any ℓ given sets of n points there
exists a labeling of each set such that the largest compatible matching has O(n2/(ℓ+1))
edges. Finally, we show that Θ(log n) copies of any set of n points are necessary
and sufficient for the existence of labelings of these point sets such that any
compatible matching consists only of a single edge.

text: "Deep learning has enabled breakthroughs in challenging computing problems
and has emerged as the standard problem-solving tool for computer vision and natural
language processing tasks.\r\nOne exception to this trend is safety-critical tasks
where robustness and resilience requirements contradict the black-box nature of
neural networks. \r\nTo deploy deep learning methods for these tasks, it is vital
to provide guarantees on neural network agents' safety and robustness criteria.
\r\nThis can be achieved by developing formal verification methods to verify the
safety and robustness properties of neural networks.\r\n\r\nOur goal is to design,
develop and assess safety verification methods for neural networks to improve
their reliability and trustworthiness in real-world applications.\r\nThis thesis
establishes techniques for the verification of compressed and adversarially trained
models as well as the design of novel neural networks for verifiably safe decision-making.\r\n\r\nFirst,
we establish the problem of verifying quantized neural networks. Quantization
is a technique that trades numerical precision for the computational efficiency
of running a neural network and is widely adopted in industry.\r\nWe show that
neglecting the reduced precision when verifying a neural network can lead to wrong
conclusions about the robustness and safety of the network, highlighting that
novel techniques for quantized network verification are necessary. We introduce
several bit-exact verification methods explicitly designed for quantized neural
networks and experimentally confirm on realistic networks that the network's robustness
and other formal properties are affected by the quantization.\r\n\r\nFurthermore,
we perform a case study providing evidence that adversarial training, a standard
technique for making neural networks more robust, has detrimental effects on the
network's performance. This robustness-accuracy tradeoff has been studied before
regarding the accuracy obtained on classification datasets where each data point
is independent of all other data points. On the other hand, we investigate the
tradeoff empirically in robot learning settings where a both, a high accuracy
and a high robustness, are desirable.\r\nOur results suggest that the negative
side-effects of adversarial training outweigh its robustness benefits in practice.\r\n\r\nFinally,
we consider the problem of verifying safety when running a Bayesian neural network
policy in a feedback loop with systems over the infinite time horizon. Bayesian
neural networks are probabilistic models for learning uncertainties in the data
and are therefore often used on robotic and healthcare applications where data
is inherently stochastic.\r\nWe introduce a method for recalibrating Bayesian
neural networks so that they yield probability distributions over safe decisions
only.\r\nOur method learns a safety certificate that guarantees safety over the
infinite time horizon to determine which decisions are safe in every possible
state of the system.\r\nWe demonstrate the effectiveness of our approach on a
series of reinforcement learning benchmarks."

text: 'We introduce end-to-end inverse design for multi-channel imaging, in which
a nanophotonic frontend is optimized in conjunction with an image-processing backend
to extract depth, spectral and polarization channels from a single monochrome
image. Unlike diffractive optics, we show that subwavelength-scale “metasurface”
designs can easily distinguish similar wavelength and polarization inputs. The
proposed technique integrates a single-layer metasurface frontend with an efficient
Tikhonov reconstruction backend, without any additional optics except a grayscale
sensor. Our method yields multi-channel imaging by spontaneous demultiplexing:
the metaoptics front-end separates different channels into distinct spatial domains
whose locations on the sensor are optimally discovered by the inverse-design algorithm.
We present large-area metasurface designs, compatible with standard lithography,
for multi-spectral imaging, depth-spectral imaging, and “all-in-one” spectro-polarimetric-depth
imaging with robust reconstruction performance (≲ 10% error with 1% detector noise).
In contrast to neural networks, our framework is physically interpretable and
does not require large training sets. It can be used to reconstruct arbitrary
three-dimensional scenes with full multi-wavelength spectra and polarization textures.'

text: 'Bombardment of materials by high-energy particles often leads to light emission
in a process known as scintillation. Scintillation has widespread applications
in medical imaging, x-ray nondestructive inspection, electron microscopy, and
high-energy particle detectors. Most research focuses on finding materials with
brighter, faster, and more controlled scintillation. We developed a unified theory
of nanophotonic scintillators that accounts for the key aspects of scintillation:
energy loss by high-energy particles, and light emission by non-equilibrium electrons
in nanostructured optical systems. We then devised an approach based on integrating
nanophotonic structures into scintillators to enhance their emission, obtaining
nearly an order-of-magnitude enhancement in both electron-induced and x-ray–induced
scintillation. Our framework should enable the development of a new class of brighter,
faster, and higher-resolution scintillators with tailored and optimized performance.'

text: Optical metasurfaces have been heralded as the platform to integrate multiple
functionalities in a compact form-factor, with the potential to replace bulky
optical components. A central stepping stone toward realizing this promise is
the demonstration of multifunctionality under several constraints (e.g., at multiple
incident wavelengths and/or angles) in a single device, an achievement being hampered
by design limitations inherent to single-layer planar geometries. Here, we propose
a framework for the inverse design of multilayer metaoptics via topology optimization,
showing that even few-wavelength thick devices can achieve high-efficiency multifunctionality,
such as multiangle light concentration and plan-achromaticity. We embody our framework
in multiple closely spaced patterned layers of a low-index polymer, with fabrication
constraints specific to this platform enforced in the optimization process. We
experimentally demonstrate our approach with an inverse-designed 3D-printed light
concentrator working at five different nonparaxial angles of incidence. Our framework
paves the way toward realizing multifunctional ultracompact 3D nanophotonic devices.

text: Controlling the multistage photoresponsivity remains a challenge, in part,
due to the spontaneous tautomerization between isomers. Herein, we present a strategy
to access three independent states (linear, cyclic keto, and cyclic enolate) of
crown ether (CE)-substituted donor–acceptor Stenhouse adducts (DASAs) by limiting
the tautomerization of the closed isomers. The linear–cyclic keto isomerization
is reversibly triggered by treatment with metal ions (Na+ or K+) and CE, while
the linear–cyclic enolate isomerization is induced by green light and heat. Density
functional theory and molecular dynamics calculation results suggest that the
steric effect and supramolecular interaction between the electron-donating and
electron-withdrawing moieties play an important role in hindering the tautomerization
between cyclic keto and cyclic enolate DASA-CE. The strategy to influence key
steps in the photoswitching process inspires well-controlled multistage isomerization
of photoresponsive molecules.

text: We investigate the influence of the host matrix on the photothermally driven
actuation performance of negatively photochromic, donor−acceptor Stenhouse adduct
(DASA)-based polymers. Using a modular Diels−Alder “click” platform, we designed
polymeric materials with varying DASA incorporation and investigated the relationships
between the material composition and the resulting physical, mechanical, and photoswitching
properties. We demonstrate that increasing the DASA concentration in polymer conjugates
has a dramatic effect on the material’s physical and mechanical properties, such
as the glass transition temperature (Tg) and elastic modulus, as well as the photoswitching
properties, which are found to be highly dependent on Tg. We establish using a
simple photoresponsive bilayer that actuation performance is controlled by the
bilayer stiffness rather than the photochrome incorporation of DASA. Finally,
we report and compare the light-induced property changes in Tg and the elastic
modulus between the materials comprising the open or closed forms of DASAs. Our
results demonstrate the importance of designing a material that is stiff enough
to provide the mechanical strength required for actuation under load, but soft
enough to reversibly switch at the operational temperature and provide key considerations
for the development of application-geared photoswitchable materials.

text: Donor–acceptor Stenhouse adducts (DASA) are a reported class of visible-light-activated
photoswitches. DASA synthesis involves two steps using furfural as starting material,
while their complex photoswitching mechanism consists both of actinic and thermal
steps. As a result of their visible-light activation, negative photochromism,
large volume and polarity change, and wavelength tunability, DASAs present significant
promise toward light-activated materials. In the years since their first report
in 2014, a number of applications have utilized DASA ranging from selective cargo
release over controlled phase transfer to directed flow in solution.

text: The ability of molecular photoswitches to convert on/off responses into large
macroscale property change is fundamental to light-responsive materials. However,
moving beyond simple binary responses necessitates the introduction of new elements
that control the chemistry of the photoswitching process at the molecular scale.
To achieve this goal, we designed, synthesized and developed a single photochrome,
based on a modified donor–acceptor Stenhouse adduct (DASA), capable of independently
addressing multiple molecular states. The multi-stage photoswitch enables complex
switching phenomena. To demonstrate this, we show spatial control of the transformation
of a three-stage photoswitch by tuning the population of intermediates along the
multi-step reaction pathway of the DASAs without interfering with either the first
or final stage. This allows for a photonic three-stage logic gate where the secondary
wavelength solely negates the input of the primary wavelength. These results provide
a new strategy to move beyond traditional on/off binary photochromic systems and
enable the design of future molecular logic systems.

text: DFT calculations were used to find an optimal substitution site on the triene
backbone of a donor–acceptor Stenhouse adduct photoswitch to tune the equillibrium
and switching kinetics of DASA without modifying the donor and acceptor groups.
Using this approach we demonstrate a new means to tuning DASA based photoswitches
by increasing the energy of the closed form relative to the open form. To highlight
the potential of this approach a new DASA derivative bearing a methyl substituent
on the 5-position of the triene was synthesized and the effect of this substitution
was studied using 1H NMR spectroscopy, time-dependent UV-Vis and solvatochromic
analysis. The new DASA derivative shows a higher dark equillibrium, favoring the
open form, and drastically faster thermal recovery than the unsubstituted derivative
with the same donor and acceptor.

text: Empirical essays of fitness landscapes suggest that they may be rugged, that
is having multiple fitness peaks. Such fitness landscapes, those that have multiple
peaks, necessarily have special local structures, called reciprocal sign epistasis
(Poelwijk et al. in J Theor Biol 272:141–144, 2011). Here, we investigate the
quantitative relationship between the number of fitness peaks and the number of
reciprocal sign epistatic interactions. Previously, it has been shown (Poelwijk
et al. in J Theor Biol 272:141–144, 2011) that pairwise reciprocal sign epistasis
is a necessary but not sufficient condition for the existence of multiple peaks.
Applying discrete Morse theory, which to our knowledge has never been used in
this context, we extend this result by giving the minimal number of reciprocal
sign epistatic interactions required to create a given number of peaks.

text: 'Auxin has always been at the forefront of research in plant physiology and
development. Since the earliest contemplations by Julius von Sachs and Charles
Darwin, more than a century-long struggle has been waged to understand its function.
This largely reflects the failures, successes, and inevitable progress in the
entire field of plant signaling and development. Here I present 14 stations on
our long and sometimes mystical journey to understand auxin. These highlights
were selected to give a flavor of the field and to show the scope and limits of
our current knowledge. A special focus is put on features that make auxin unique
among phytohormones, such as its dynamic, directional transport network, which
integrates external and internal signals, including self-organizing feedback.
Accented are persistent mysteries and controversies. The unexpected discoveries
related to rapid auxin responses and growth regulation recently disturbed our
contentment regarding understanding of the auxin signaling mechanism. These new
revelations, along with advances in technology, usher us into a new, exciting
era in auxin research. '
acknowledgement: "The author thanks the whole community of researchers consciously
or unconsciously working on questions related to auxin, whose hard work and enthusiasm
contributed to development of this exciting story. Particular thanks go to many\r\nbrilliant
present and past members of the Friml group and our numerous excellent collaborators,
without whom my own personal journey would not be possible. The way of the cross
with its 14 stations is a popular devotion among Roman Catholics and inspires them
to make a spiritual pilgrimage through contemplation of Christ on his last day.
Its aspects of gradual progress, struggle, passion, and revelation served as an
inspiration for the formal depiction of our journey to understanding auxin as described
in this review. It is in no way intended to reflect the personal beliefs of the
author and readers. I am grateful to Nick Barton, Eva Benková, Lenka Caisová, Matyáš
Fendrych, Lukáš Fiedler, Monika Frátriková, Jarmila Frimlová, Michelle Gallei, Jakub
Hajný, Lukas Hoermayer, Alexandra Mally, Ondrˇej Novák, Jan Petrášek, Aleš Pěnčík,
