text: While tumor malignancy has been extensively studied under the prism of genetic
and epigenetic heterogeneity, tumor cell states also critically depend on reciprocal
interactions with the microenvironment. This raises the hitherto untested possibility
that heterogeneity of the untransformed tumor stroma can actively fuel malignant
progression. As biological heterogeneity is inherently difficult to control, we
adopted a reductionist approach and let tumor cells invade micro-engineered environments
harboring obstacles with precision-controlled geometry. We find that not only
the presence of obstacles, but more surprisingly their spatial disorder, causes
a drastic shift from a collective to a single-cell mode of invasion – comparable
in strength to cadherin loss. Combining live-imaging and perturbation experiments
with minimal biophysical modeling, we demonstrate that cell detachments result
both from local geometrical constraints and a global integration of spatial disorder
over time. We show that different types of microenvironments map onto different
universality classes of invasion dynamics - homogeneous substrates follow Kardar–Parisi–Zhang
(KPZ) scaling, while disordered ones exhibit exponents consistent with KPZ with
quenched disorder (KPZq). Our findings highlight generic physical principles for
how the mode of cancer cell invasion depends on environmental heterogeneity, with
potential implications to understand tumor evolution in vivo.

text: "The recent surge in high-quality open-source Generative AI text models (colloquially:
LLMs), as well as efficient finetuning techniques, have opened the possibility
of creating high-quality personalized models that generate text attuned to a specific
individual’s needs and are capable of credibly imitating their writing style by
refining an open-source model with that person’s own data. The technology to create
such models is accessible to private individuals, and training and running such
models can be done cheaply on consumer-grade hardware. While these advancements
are a huge gain for usability and privacy, this position paper argues that the
practical feasibility of impersonating specific individuals also introduces novel
safety risks. For instance, this technology enables the creation of phishing emails\r\nor
fraudulent social media accounts, based on small amounts of publicly available
text, or by the individuals themselves to escape AI text detection. We further
argue that these risks are complementary to—and distinct from—the much-discussed
risks of other impersonation attacks such as image, voice, or video deepfakes,
and are not adequately addressed by the larger research community, or the current
generation of open- and closed-source models."

text: 'The Birkhoff conjecture says that the boundary of a strictly convex integrable
billiard table is necessarily an ellipse. In this article, we consider a stronger
notion of integrability, namely, integrability close to the boundary, and prove
a local version of this conjecture: a small perturbation of almost every ellipse
that preserves integrability near the boundary, is itself an ellipse. We apply
this result to study local spectral uniqueness of ellipses using the connection
between the wave trace of the Laplacian and the dynamics near the boundary and
establish local uniqueness for almost all of them.'

text: Zero-sum stochastic games are parameterized by payoffs, transitions, and possibly
a discount rate. In this article, we study how the main solution concepts, the
discounted and undiscounted values, vary when these parameters are perturbed.
We focus on the marginal values, introduced by Mills in 1956 in the context of
matrix games—that is, the directional derivatives of the value along any fixed
perturbation. We provide a formula for the marginal values of a discounted stochastic
game. Further, under mild assumptions on the perturbation, we provide a formula
for their limit as the discount rate vanishes and for the marginal values of an
undiscounted stochastic game. We also show, via an example, that the two latter
differ in general.

sometimes impossible, problem, which existing methods are forced to soften by
allowing for map distortions or multiple patches. Instead, we propose a geometric
relaxation of the problem: We modify the input shape until it admits an overlap‐free
unfolding. We achieve this by locally displacing vertices and collapsing edges,
guided by the unfolding process. We validate our algorithm quantitatively and
qualitatively on a large dataset of complex shapes and show its proficiency by
fabricating real shapes from paper.'

text: "\"Can we do this with a new type of computer - a quantum computer?\". This
famous\r\nquotation of the brilliant Richard Feynman within a conference talk
on \"Simulating physics\r\nwith computers.” is often reverently praised as the
origin of the field of quantum computing.\r\nThe idea was to use quantum mechanical
systems itself to simulate \"Nature\", which is\r\ninherently quantum mechanical.
Now, 43 years later, the theoretical framework of how such\r\na computer can operate
has been developed. Two main important concepts for a potential\r\nquantum supremacy,
superposition and entanglement, have been exploited to design quantum\r\nalgorithms
to significantly speed up certain tasks. Yet, the specific hardware implementation\r\nis
still far from being certain, in fact the race between the most promising platforms
such as\r\nsuperconducting qubits, bosonic codes, cold atoms, trapped ions, optical
computing as well\r\nas spin qubits has recently intensified. If one also includes
the most mature applications of\r\nquantum communication technologies, secure
quantum key distribution and quantum random\r\nnumber generators, as part of a
quantum information technology ecosystem, we are confronted\r\nwith a plethora
of different materials, concepts, and also operation frequencies. While\r\nsuperconducting
qubits, bosonic codes and spin qubits work in the regime of approximately 5\r\nGHz
and are controlled by electrical fields, trapped ions, cold atoms, and optical
quantum\r\ncomputing operate with light in the infrared or visible range.\r\nConsequently,
a quantum frequency converter or microwave-optic transducer is required\r\nto
interface the different frequency domains or establish a long-range network connection\r\nwith
suitable telecom fibers. In fact, the combination of different frequency regimes
is also\r\nan essential part in our classical modern communication network, where
computations are\r\nperformed in electrical circuits and the information exchange
over longer distances happens\r\nvia optical fibers. However, the specific challenges
specific to building a quantum computer,\r\nalso apply to the development of such
a quantum frequency transducer: 1) As we deal with\r\nsingle excitations as the
carrier of information, i.e. the smallest possible quantity, the signal\r\ncan
easily be corrupted by other noise sources which needs to be avoided by all means.
This\r\nis also the reason why microwave quantum computers operate at temperature
environments\r\nclose to zero temperature (< 0.1 Kelvin) to avoid corruption by
thermal noise. 2) The\r\nfrequency interface generally needs to preserve the phase
of the signal as an essential part\r\nof the quantum state. And 3) Quantum signals
cannot be copied which would be a typical\r\nstrategy to account for errors in
classical computers. And finally, there is a challenge specific to\r\nmicrowave-optic
transducers: While quantum computers are operating in one specific frequency\r\ndomain,
microwave-optic transducers combine microwave and optical fields in one device.\r\nThis
results in the particular challenge that high-energy optical radiation, which
is usually\r\nwell-shielded from superconducting microwave quantum processors,
are now an essential part\r\nof the device. The concomitant optical radiation
in the operating transducer will inevitably\r\nhave a detrimental effect on the
superconducting microwave components. Together with the\r\nrequirement of minimal
background noise for quantum-limited operation as described above,\r\nv\r\nheating
from the absorption of optical photons within the same device where single microwave\r\nexcitations
are processed forms a formidable challenge.\r\nThis thesis aims to address this
challenge by developing microwave-optic transducers where\r\nthe impact of optical
absorption on superconducting circuits in general and superconducting\r\nqubits
specifically can be mitigated. In our first approach, we developed a compact device\r\nwith
optimized interaction strengths between the different frequency domains. This
minimizes\r\nthe optical powers used for transducer operation and thus the optical
absorption heating. This\r\nwork was - to the best of our knowledge - the first
comprehensive noise study, in an integrated\r\nmicrowave-optic transducer. Unfortunately,
we saw that the optical absorption heating added\r\nnoise way above a single excitation.
Consequently, a potential quantum signal would have\r\nbeen buried in the noise,
added by the transduction.\r\nBuilding on this insight, we utilized a three-dimensional
microwave-optic transducer instead\r\nof an integrated device. The larger heat
capacity of the macroscopic device with a size\r\nof a few millimeters can absorb
a larger fraction of the optical heating before it increases\r\nthe temperature
of the device. This allowed us to interface the transducer directly with a\r\nsuperconducting
qubit to readout the qubit state in a novel all-optical manner. We showed\r\nthat
the microwave-optic transducer can be operated in a regime in which optical fields
don’t\r\nharm the sensitive qubit. This is an important prerequisite for the operation
of microwave-optic\r\ntransducers in conjunction with microwave quantum processors
and brings the integration and\r\nseamless orchestration of different frequency
components in a quantum network a step closer.\r\n"

text: 'Our brain has remarkable computational power, generating sophisticated behaviors,
storing memories over an individual’s lifetime, and producing higher cognitive
functions. However, little of our neuroscience knowledge covers the human brain.
Is this organ truly unique, or is it a scaled version of the extensively studied
rodent brain? Combining multicellular patch-clamp recording with expansion-based
superresolution microscopy and full-scale modeling, we determined the cellular
and microcircuit properties of the human hippocampal CA3 region, a fundamental
circuit for memory storage. In contrast to neocortical networks, human hippocampal
CA3 displayed sparse connectivity, providing a circuit architecture that maximizes
associational power. Human synapses showed unique reliability, high precision,
and long integration times, exhibiting both species- and circuit-specific properties.
Together with expanded neuronal numbers, these circuit characteristics greatly
enhanced the memory storage capacity of CA3. Our results reveal distinct microcircuit
properties of the human hippocampus and begin to unravel the inner workings of
our most complex organ. '

text: Ternary liquid-like thermoelectric materials have garnered significant attention
due to their ultra-low lattice thermal conductivity. Among these, Ag8SnSe6 stands
out for its exceptionally low sound velocity and thermal conductivity. However,
the inherent poor electrical conductivity and suboptimal thermoelectric properties
of Ag8SnSe6 necessitate further improvement. Here, a novel approach is initiated
to enhance the thermoelectric properties of Ag8SnSe6 by combining low-dimensionalization
with intrinsic doping. For the first time, this work successfully synthesizes
single-phase Ag8SnSe6 nanocrystals, ≈10 nm in size, with the correct phase and
composition using a robust and reliable colloidal method. This approach represents
a significant improvement over previous reports on this material. Reducing the
crystal domains of Ag8SnSe6 to the nanoscale induces quantum confinement effects,
increasing the density of states near the Fermi surface. It also introduces additional
grain boundaries, which lower the lattice thermal conductivity and simplify structural
design. Moreover, incorporating small amounts of Sn nanopowder into the Ag8SnSe6
nanocrystals before consolidation further enhances the thermoelectric performance.
Sn acts as a donor dopant, increasing the electronic concentration while at the
same time improving their mobility by reducing interface barriers, thus significantly
improving the material transport properties. Additionally, the presence of Sn
leads to the formation of point defects, dislocations, and secondary phases, which
increase phonon scattering and further reduce the thermal conductivity. Through
this synergistic optimization, the figure of merit shows a significant increase
across a wide temperature range. Overall, a strategy is presented for the controlled
preparation of Ag8SnSe6 nanocrystals, the decoupling of their electrical and thermal
transport, and the practical application of this material to thermoelectric single-leg
modules.

text: "Topological Data Analysis (TDA) is a discipline utilizing the mathematical
field of topology to study data, most prominently collections of point sets. This
thesis summarizes three projects related to computations in TDA.\r\n\r\nThe first
one establishes a variant of TDA for chromatic point sets, where each point is
given a color. For example, we are given positions of cells within a tumor microenvironment,
and color the cancerous cells red, and the immune cells blue.\r\n\r\nThe aim is
then to give a quantitative description of how the two or more sets of points
spatially interact. Building on image, kernel and cokernel variants of persistent
homology, we suggest six-packs of persistent diagrams as such a descriptor.\r\n\r\nWe
describe a construction of a chromatic alpha complex, which enables efficient
computation of several variants of the six-packs. We give topological descriptions
of natural subcomplexes of the chromatic alpha complex, and show that the radii
of the simplices form a discrete Morse function. Finally, we provide an implementation
of the presented chromatic TDA pipeline.\r\n\r\nThe second part aims to translate
a powerful tool of sheaf theory to elementary terms using labeled matrices. The
goal is to enable their use in computational settings. We show that derived categories
of sheaves over finite posets have, up to isomorphism, unique objects---minimal
injective resolutions---and give a concrete algorithm to compute them. We further
describe simple algorithms to compute derived pushforwards and pullbacks for monotonic
maps, and their proper variants for inclusions, and demonstrate their tractability
by providing an implementation. Finally, we suggest a discrete definition of microsupport
and show desirable properties inspired by discrete Morse theory.\r\n\r\nIn the
last part, we present a collection of observations about collapses. We give a
characterization of collapsibility in terms of unitriangular submatrices of the
boundary matrix, a cotree-tree decomposition, and the optimal solution to a variant
of the Procrustes problem. We establish relation between dual collapses and relative
Morse theory and pose several open questions. Finally, focusing on complexes embedded
in the three-dimensional Euclidean space, we describe a relation between the collapsibility
and the triviality of a polygonal knot."

text: 'Rotations are found in physics problems at all scales: from spatial motion
of celestial bodies, to transitions between quantum states of atoms and molecules.
Mathematically, they represent a fundamental class of transformations and symmetries.
Unlike spatial displacements, rotational transformations in three-dimensional
space are non-commutative: the result of applying a sequence of rotations depends
on the order of these operations. This feature makes the emergent physics that
involves rotations rather intricate, but instrumental for studies of highly-interconnected
many-body systems. In the presence of an environment, rotational properties of
an object change, due to the interaction with particles of the environment. Owing
to the complexity of this interaction, it can be engineered to exhibit certain
properties of interest. In this Thesis, we examine several scenarios of how the
rotational behavior of an impurity can be modified by interactions with its environment.'

text: "We present a sample of 1956 individual stellar clumps at redshift 0.7 < z
< 10, detected with JWST/NIRCam in 476 galaxies lensed by the galaxy cluster Abell2744.
The lensed clumps present magnifications ranging between μ = 1.8 and μ = 300.
We perform simultaneous size-photometry estimates in 20 JWST/NIRCam median and
broad-band filters from 0.7 to 5 μm.\r\nSpectral energy distribution (SED) fitting
analyses enable us to recover the physical properties of the clumps. The majority
of the clumps are spatially resolved and have effective radii in the range Reff
= 10–700 pc. We restrict this first study to the 1751 post-reionization era clumps
with redshift < 5.5. We find a significant evolution of the average clump ages,
star formation rates (SFRs), SFR surface densities, and metallicity with increasing
redshift, while median stellar mass and stellar mass surface densities are similar
in the probed redshift range. We observe a strong correlation between the clump
properties and the properties of their host galaxies, with more massive galaxies
hosting more massive and older clumps. We find that clumps closer to their host
galactic centre are on average more massive, while their ages do not show clear
sign of migration. We find that clumps at cosmic noon sample the upper-mass end
of the mass function to higher masses than at z > 3, reflecting the rapid increase
towards the peak of the cosmic star formation history. We conclude that the results
achieved over the studied redshift range are in agreement with expectation of
in situ clump formation scenario from large-scale disc fragmentation. "

text: Modern experimental methods enable the creation of self-assembly building
blocks with tunable interactions, but optimally exploiting this tunability for
the self-assembly of desired structures remains an important challenge. Many studies
of this inverse problem start with the so-called fully addressable limit, where
every particle in a target structure is different. This leads to clear design
principles that often result in high assembly yield, but it is not a scalable
approach—at some point, one must grapple with “reusing” building blocks, which
lowers the degree of addressability and may cause a multitude of off-target structures
to form, complicating the design process. Here, we solve a key obstacle preventing
robust inverse design in the “semiaddressable regime” by developing a highly efficient
algorithm that enumerates all structures that can be formed from a given set of
building blocks. By combining this with established partition-function-based yield
calculations, we show that it is almost always possible to find economical semiaddressable
designs where the entropic gain from reusing building blocks outweighs the presence
of off-target structures and even increases the yield of the target. Thus, not
only does our enumeration algorithm enable robust and scalable inverse design
in the semiaddressable regime, our results demonstrate that it is possible to
operate in this regime while maintaining the level of control often associated
with full addressability.

text: "The medial habenula (MHb) is implicated in regulating emotional responses\r\nto
aversive events. Studies in zebrafish have identified a remarkable morphological\r\nleft-right
asymmetry in the dorsal habenula (zebrafish equivalent of mammalian\r\nMHb)-to-interpeduncular
nucleus (IPN) pathway and its left-side specific role in\r\nmodulating fear responses.
However, there is little evidence for structural or\r\nfunctional lateralization
in the mammalian MHb-IPN pathway.\r\nHere, I investigated the synaptic properties
of the left and right MHb\r\nafferents to the IPN in mice and addressed whether
these synaptic connections\r\nselectively influence the expression of conditioned
fear in mice. My findings reveal\r\nthat each individual IPN neuron receives inputs
from both left and right MHb.\r\nElectrophysiological recordings from the same
postsynaptic IPN neurons\r\ndemonstrate that the left MHb-originating synapses
exhibit lower release\r\nprobability and higher \U0001D6FE-aminobutyric acid type
B receptor (GABABR)-mediated\r\npotentiation compared to the right MHb-originating
synapses. Interestingly,\r\nchemogenetic inhibition of cholinergic neurons in
the left but not the right MHb\r\nsignificantly attenuated cue-dependent fear
recall. Furthermore, conditional\r\ndeletion of GABABR in the left MHb interfered
with the recall of cued fear memory,\r\nwhereas that in the right MHb neurons
spared fear memory expression.\r\nCollectively, I demonstrate a functional asymmetry
of the MHb in mice,\r\nrevealing a predominant role for GABABR-mediated signaling
in the left MHb-IPN\r\npathway in the modulation of fear memories. These findings
suggest that\r\nlateralized pathways could represent a fundamental principle in
the neural\r\nregulation of emotion across species."

text: "Social interaction networks of insect colonies facilitate efficient information
exchange and\r\ndemonstrate adaptive changes to mitigate disease transmission.
While circadian rhythms\r\ninfluence individual behaviour, their role in shaping
colony-level defences against pathogens\r\nremains unexplored. Here, we investigate
whether social networks of the black garden ant,\r\nLasius niger, exhibit circadian
rhythms and how these rhythms influence disease vulnerability\r\nwhen colonies
are exposed to a pathogen during the day or the night.\r\nWe first establish baseline
daily variations in activity and network dynamics in pathogen-free\r\ncolonies,
revealing constitutive daily fluctuations in disease susceptibility. Subsequently,
we\r\nexamine pathogen-induced changes in sanitary care and network dynamics by
exposing\r\nforagers to a natural pathogen (Metarhizium brunneum) during either
the day or the night.\r\nIndividual pathogen loads were measured after a nine-hour
post-exposure period to evaluate\r\ntransmission outcomes.\r\nOur results demonstrate
that diurnal ant colonies maintain robust circadian patterns in network\r\nproperties
while flexibly adapting to pathogen exposure. Ants upregulate sanitary care\r\nirrespective
of exposure timing, prioritising the protection of the valuable colony centre\r\nconsisting
of nurses and the queen. These findings underscore the robustness and adaptability\r\nof
ant colonies in balancing circadian rhythms with effective social immune responses."

text: "Crustaceans are a large group of arthropods with a great diversity of species
and\r\ndifferent types of sex determination systems and reproductive modes (Subramoniam,
2017).\r\nThis makes them a great model for exploring the evolution of sex chromosomes
and sexual\r\ndimorphism and investigating the evolutionary mechanisms driving
and maintaining the\r\ndiversity of reproductive systems. Within this taxon, Brine
shrimp of the genus Artemia, a\r\nbranchiopod crustacean, are well suited for
such explorations, as they have both highly\r\ndimorphic traits and closely related
sexual and asexual species. Although brine shrimp are\r\nknown to have ZW sex
chromosomes (Bowen, 1963; Parraguez et al., 2009), the sex\r\nchromosomes are
still not well characterized at the genomic level, the sex-determination gene\r\nis
unknown, and it is still unclear whether the same sex chromosomes as shared by
the\r\ndifferent species.\r\nThe first part of this thesis was to characterize
the Z and W chromosomes in Artemia\r\nusing an array of methods, from generating
multiple chromosome and contig level genome\r\nassemblies to identifying W-linked
scaffolds and transcripts in multiple species using k-mer\r\nbased approaches.\r\nThe
second part tackles the conservation of the cell type specific regulatory pathways\r\nin
the female reproductive system between Artemia and Drosophila, and the expression
of the\r\nZ-specific region throughout meiosis using single-nucleus RNA-seq data.
Our results show\r\nthat germline cells lack dosage compensation, with a subset
of cells showing evidence of\r\nextreme repression of the Z chromosome.\r\nWith
multiple sexual species and several asexual lineages of parthenogenetic females\r\nthat
produce rare males at low frequencies, Brine shrimp present the perfect opportunity
to\r\nexplore the transition to asexuality and shed light on the prerequisites
and repercussions of\r\nthe form of modified meiosis maintaining the asexual lineages.
The last chapter is an\r\ninvestigation of the molecular pathways involved in
asexual reproduction in Artemia using\r\nnewly generated single nucleus RNAseq
and WGS data and previously published data. "

text: "Rotations constitute one of the fundamental symmetries in physics, characterized
by their intricate group structure and infinite dimensional representations. In
contrast to classical rotations, quantum mechanics unveils the SO(3) symmetry
group structure, manifesting in phenomena without classical counterparts, from
angular momentum quantization to non-trivial addition of angular momenta.\r\nWhile
most studies of topological physics have focused on two-band systems, the SO(3)
symmetry group of quantum rotors offers an inherently more complex platform with
unprecedented possibilities for exploring topological phenomena. Despite their
ubiquity in nature– from molecules to nanorotors– their potential for hosting
topological phases has remained largely unexamined.\r\nIn this thesis, we mainly
focus on periodically driven linear molecules as a prototype for studying topological
phenomena in quantum rotors. Recent technological advances in coherent control
of molecules, particularly through precisely shaped laser pulses, have made it
possible to investigate linear rotors in the context of topology. While planar
rotors have received some attention in recent years, threedimensional rotors–particularly
linear molecules–harbor substantially richer topological phenomena due to their
non-abelian nature and their additional angular degrees of freedom. We demonstrate
that these systems can host novel edge states and topological features fundamentally
impossible in planar systems.\r\nWe begin by establishing a theoretical bridge
between periodically kicked rotors and \"crystalline\" lattices in angular momentum
space. Using non-interacting linear molecules as our primary example, we show
how quantum interference and revival patterns lead to the possibility to simulate
band models with arbitrary number of bands N. While our framework applies to various
quantum rotors, including nanorotors and kicked Bose-Einstein condensates, linear\r\nmolecules
provide an ideal experimental platform due to their abovementioned precise controllability.\r\nThe
core of this work examines adiabatic dynamics of 3D quantum rotors, establishing
a geometric framework based on the Euler class to characterize its non-abelian
topology. The non-Hermitian nature of the system enables novel braiding behaviors
and topological transitions impossible in static systems, leading to an anomalous
Dirac string phase with edge states in each gap, even though the Berry phases
are all zero. These features can be directly observed through\r\nmolecular alignment
and rotational level populations.\r\nThese findings establish quantum rotors as
an alternative platform for studying multi-band topological physics, while suggesting
practical implementations for quantum computation where topological protection
could offer natural resilience against decoherence. The rich structure of three-dimensional
rotation groups, combined with the tunability of topological features through
driving parameters, makes this platform particularly valuable for exploring fundamental\r\nphysics
and developing quantum technologies."
