text: "Context. Space asteroseismology is revolutionizing our knowledge of the internal
structure and dynamics of stars. A breakthrough is ongoing with the recent discoveries
of signatures of strong magnetic fields in the core of red giant stars. The key
signature for such a detection is the asymmetry these fields induce in the frequency
splittings of observed dipolar mixed gravito-acoustic modes.\r\nAims. We investigate
the ability of the observed asymmetries of the frequency splittings of dipolar
mixed modes to constrain the geometrical properties of deep magnetic fields.\r\nMethods.
We used the powerful analytical Racah-Wigner algebra used in quantum mechanics
to characterize the geometrical couplings of dipolar mixed oscillation modes with
various realistically plausible topologies of fossil magnetic fields. We also
computed the induced perturbation of their frequencies.\r\nResults. First, in
the case of an oblique magnetic dipole, we provide the exact analytical expression
of the asymmetry as a function of the angle between the rotation and magnetic
axes. Its value provides a direct measure of this angle. Second, considering a
combination of axisymmetric dipolar and quadrupolar fields, we show how the asymmetry
is blind to the unraveling of the relative strength and sign of each component.
Finally, in the case of a given multipole, we show that a negative asymmetry is
a signature of non-axisymmetric topologies.\r\nConclusions. Asymmetries of dipolar
mixed modes provide a key bit of information on the geometrical topology of deep
fossil magnetic fields, but this is insufficient on its own. Asteroseismic constraints
should therefore be combined with spectropolarimetric observations and numerical
simulations, which aim to predict the more probable stable large-scale geometries."

text: "Superconductor-semiconductor heterostructures currently capture a significant
amount of research interest and they serve as the physical platform in many proposals
towards topological quantum computation.\r\nDespite being under extensive investigations,
historically using transport techniques, the basic properties of the interface
between the superconductor and the semiconductor remain to be understood.\r\n\r\nIn
this thesis, two separate studies on the Al-InAs heterostructures are reported
with the first focusing on the physics of the material motivated by the emergence
of a new phase, the Bogoliubov-Fermi surface. \r\nThe second focuses on a technological
application, a gate-tunable Josephson parametric amplifier.\r\n\r\nIn the first
study, we investigate the hypothesized unconventional nature of the induced superconductivity
at the interface between the Al thin film and the InAs quantum well.\r\nWe embed
a two-dimensional Al-InAs hybrid system in a resonant microwave circuit allowing
measurements of change in inductance.\r\nThe behaviour of the resonance in a range
of temperature and in-plane magnetic field has been studied and compared with
the theory of conventional s-wave superconductor and a two-component theory that
includes both contribution of the $s$-wave pairing in Al and the intraband $p
\\pm ip$ pairing in InAs.\r\nMeasuring the temperature dependence of resonant
frequency, no discrepancy is found between data and the conventional theory.\r\nWe
observe the breakdown of superconductivity due to an applied magnetic field which
contradicts the conventional theory.\r\nIn contrast, the data can be captured
quantitatively by fitting to a two-component model.\r\nWe find the evidence of
the intraband $p \\pm ip$ pairing in the InAs and the emergence of the Bogoliubov-Fermi
surfaces due to magnetic field with the characteristic value $B^* = 0.33~\\mathrm{T}$.\r\nFrom
the fits, the sheet resistance of Al, the carrier density and mobility in InAs
are determined.\r\nBy systematically studying the anisotropy of the circuit response,
we find weak anisotropy for $B < B^*$ and increasingly strong anisotropy for $B
> B^*$ resulting in a pronounced two-lobe structure in polar plot of frequency
versus field angle.\r\nStrong resemblance between the field dependence of dissipation
and superfluid density hints at a hidden signature of the Bogoliubov-Fermi surface
that is burried in the dissipation data.\r\n\r\nIn the second study, we realize
a parametric amplifier with a Josephson field effect transistor as the active
element.\r\nThe device's modest construction consists of a gated SNS weak link
embedded at the center of a coplanar waveguide resonator.\r\nBy applying a gate
voltage, the resonant frequency is field-effect tunable over a range of 2 GHz.\r\nModelling
the JoFET minimally as a parallel RL circuit, the dissipation introduced by the
JoFET can be quantitatively related to the gate voltage.\r\nWe observed gate-tunable
Kerr nonlinearity qualitatively in line with expectation.\r\nThe JoFET amplifier
has 20 dB of gain, 4 MHz of instantaneous bandwidth, and a 1dB compression point
of -125.5 dBm when operated at a fixed resonant frequency.\r\nIn general, the
signal-to-noise ratio is improved by 5-7 dB when the JoFET amplifier is activated
compared.\r\nThe noise of the measurement chain and insertion loss of relevant
circuit elements are calibrated to determine the expected and the real noise performance
of the JoFET amplifier.\r\nAs a quantification of the noise performance, the measured
total input-referred noise of the JoFET amplifier is in good agreement with the
estimated expectation which takes device loss into account.\r\nWe found that the
noise performance of the device reported in this document approaches one photon
of total input-referred added noise which is the quantum limit imposed in nondegenerate
parametric amplifier."

text: We unveil a powerful method for the stabilization of laser injection locking
based on sensing variations in the output beam ellipticity of an optically seeded
laser. The effect arises due to an interference between the seeding beam and the
injected laser output. We demonstrate the method for a commercial semiconductor
laser without the need for any internal changes to the readily operational injection
locked laser system that was used. The method can also be used to increase the
mode-hop free tuning range of lasers, and has the potential to fill a void in
the low-noise laser industry.

text: We study the impact of finite-range physics on the zero-range-model analysis
of three-body recombination in ultracold atoms. We find that temperature dependence
of the zero-range parameters can vary from one set of measurements to another
as it may be driven by the distribution of error bars in the experiment, and not
by the underlying three-body physics. To study finite-temperature effects in three-body
recombination beyond the zero-range physics, we introduce and examine a finite-range
model based upon a hyperspherical formalism. The systematic error discussed in
this Letter may provide a significant contribution to the error bars of measured
three-body parameters.

text: "Given a bipartite graph G, the graphical matrix space SG consists of\r\nmatrices
whose non-zero entries can only be at those positions corresponding to edges in
G. Tutte (J. London Math. Soc., 1947), Edmonds\r\n(J. Res. Nat. Bur. Standards
Sect. B, 1967) and Lov´asz (FCT, 1979) observed connections between perfect matchings
in G and full-rank matrices\r\nin SG. Dieudonn´e (Arch. Math., 1948) proved a
tight upper bound on\r\nthe dimensions of those matrix spaces containing only
singular matrices.\r\nThe starting point of this paper is a simultaneous generalization
of these\r\ntwo classical results: we show that the largest dimension over subspaces\r\nof
SG containing only singular matrices is equal to the maximum size over\r\nsubgraphs
of G without perfect matchings, based on Meshulam’s proof of\r\nDieudonn´e’s result
(Quart. J. Math., 1985).\r\nStarting from this result, we go on to establish more
connections\r\nbetween properties of graphs and matrix spaces. For example, we\r\nestablish
connections between acyclicity and nilpotency, between strong\r\nconnectivity
and irreducibility, and between isomorphism and\r\nconjugacy/congruence. For each
connection, we study three types of correspondences, namely the basic correspondence,
the inherited correspondence (for subgraphs and subspaces), and the induced correspondence\r\n(for
induced subgraphs and restrictions). Some correspondences lead to\r\nintriguing
generalizations of classical results, such as Dieudonn´e’s result\r\nmentioned
above, and a celebrated theorem of Gerstenhaber regarding the\r\nlargest dimension
of nil matrix spaces (Amer. J. Math., 1958).\r\nFinally, we show some implications
of our results to quantum information and present open problems in computational
complexity motivated\r\nby these results."

text: 'The size Ramsey number of a graph H is defined as the minimum number of edges
in a graph G such that there is a monochromatic copy of H in every two-coloring
of E(G). The size Ramsey number was introduced by Erdős, Faudree, Rousseau, and
Schelp in 1978 and they ended their foundational paper by asking whether one can
determine up to a constant factor the size Ramsey numbers of three families of
graphs: complete bipartite graphs, book graphs (obtained by adding many common
neighbors to the vertices of a clique), and starburst graphs (obtained by adding
many pendant edges to each vertex of a clique). In this paper, we completely resolve
the latter two questions and make substantial progress on the first by determining
the size Ramsey number of Ks,t up to a constant factor for all t=Ω(s log s).'

text: "Mutation rates represent the net result of complex interactions among various\r\ncellular
processes and can dramatically influence the evolutionary fate of\r\nmicrobial
populations. However, many popular techniques used to study\r\nmutations are subject
to the confounding effects of heredity and the subtleties\r\nof adaptation to
selection, all of which make it difficult to observe any dynamic\r\nresponses
of mutation rates to fitness challenges. Furthermore, in spite of the\r\nubiquity
of quorum sensing systems across the bacterial domain and relevance\r\nfor many
physiological behaviors, the effects of such mechanisms on mutation\r\nrate and
adaptation remain poorly understood. In the following work, I\r\npresent the development
of a microfluidic droplet-based method to measure\r\nsingle base-pair mutation
rates in growing populations of the bacterium\r\nEscherichia coli. I use this
method to observe a stress-induced increase in\r\nmutation rate that is mediated
by luxS, a highly conserved bacterial quorum\r\nsensing component. I also show
that the aforementioned increase in mutation\r\nrate, and its associated control
by luxS, corresponds to a higher degree of\r\nadaptability under competitive environments."

text: So-called spontaneous activity is a central hallmark of most nervous systems.
Such non-causal firing is contrary to the tenet of spikes as a means of communication,
and its purpose remains unclear. We propose that self-initiated firing can serve
as a release valve to protect neurons from the toxic conditions arising in mitochondria
from lower-than-baseline energy consumption. To demonstrate the viability of our
hypothesis, we built a set of models that incorporate recent experimental results
indicating homeostatic control of metabolic products—Adenosine triphosphate (ATP),
adenosine diphosphate (ADP), and reactive oxygen species (ROS)—by changes in firing.
We explore the relationship of metabolic cost of spiking with its effect on the
temporal patterning of spikes and reproduce experimentally observed changes in
intrinsic firing in the fruitfly dorsal fan-shaped body neuron in a model with
ROS-modulated potassium channels. We also show that metabolic spiking homeostasis
can produce indefinitely sustained avalanche dynamics in cortical circuits. Our
theory can account for key features of neuronal activity observed in many studies
ranging from ion channel function all the way to resting state dynamics. We finish
with a set of experimental predictions that would confirm an integrated, crucial
role for metabolically regulated spiking and firmly link metabolic homeostasis
and neuronal function.

text: 'The clique removal lemma says that for every ≥r 3 andε > 0, there exists
some δ > 0 so that every n‐vertex graph G with fewer than δnr copies of K r can
be made K r ‐free by removing at most εn2 edges. The dependence of δ on ε in this
result is notoriously difficult to determine: it is known that δ−1 must be at
least super‐polynomial in ε−1, and that it is at most of tower type in εlog −1.
We prove that if one imposes an appropriate minimum degree condition on G, then
one can actually take δ to be a linear function of ε in the clique removal lemma.
Moreover, we determine the threshold for such a minimum degree requirement, showing
that above this threshold we have linear bounds, whereas below the threshold the
bounds are once again super‐polynomial, as in the unrestricted removal lemma.
We also investigate this question for other graphs besides cliques, and prove
some general results about how minimum degree conditions affect the bounds in
the graph removal lemma.'

text: "The book graph \U0001D435(\U0001D458)\r\n\U0001D45B consists of \U0001D45B
copies of \U0001D43E\U0001D458+1 joined along a common \U0001D43E\U0001D458. In
the prequel to this paper, we studied the diagonal Ramsey number \U0001D45F(\U0001D435(\U0001D458)\r\n\U0001D45B,\U0001D435(\U0001D458)\r\n\U0001D45B).
Here we consider the natural off-diagonal variant \U0001D45F(\U0001D435(\U0001D458)\r\n\U0001D450\U0001D45B,\U0001D435(\U0001D458)\r\n\U0001D45B)
for fixed \U0001D450 ∈(0,1]. In this more general setting, we show that an interesting
dichotomy emerges: for very small \U0001D450, a simple \U0001D458-partite construction
dictates the Ramsey function and all nearly-extremal colourings are close to being
\U0001D458-partite, while, for \U0001D450 bounded away from 0, random colourings
of an appropriate density are asymptotically optimal and all nearly-extremal colourings
are quasirandom. Our investigations also open up a range of questions about what
happens for intermediate values of \U0001D450.\r\n\r\n"

text: "Extending an earlier conjecture of Erdős, Burr and Rosta conjectured that
among all two-colorings of the edges of a complete graph, the uniformly random
coloring asymptotically minimizes the number of monochromatic copies of any fixed
graph H. This conjecture was disproved independently by Sidorenko and Thomason.
The first author later found quantitatively stronger counterexamples, using the
Turán coloring, in which one of the two colors spans a balanced complete multipartite
graph.\r\nWe prove that the Turán coloring is extremal for an infinite family
of graphs, and that it is the unique extremal coloring. This yields the first
determination of the Ramsey multiplicity constant of a graph for which the Burr--Rosta
conjecture fails.\r\nWe also prove an analogous three-color result. In this case,
our result is conditional on a certain natural conjecture on the behavior of two-color
Ramsey numbers."

text: "The Ramsey number r(G,H) is the minimum N such that every graph on N vertices
contains G as a subgraph or its complement contains H as a subgraph. For integers
n≥k≥1, the k-book Bk,n is the graph on n vertices consisting of a copy of Kk,
called the spine, as well as n−k additional vertices each adjacent to every vertex
of the spine and non-adjacent to each other. A connected graph H on n vertices
is called p-good if r(Kp,H)=(p−1)(n−1)+1. Nikiforov and Rousseau proved that if
n is sufficiently large in terms of p and k, then Bk,n is p-good. Their proof
uses Szemerédi's regularity lemma and gives a tower-type bound on n. We give a
short new proof that avoids using the regularity method and shows that every Bk,n
with n≥2k10p is p-good.\r\nUsing Szemerédi's regularity lemma, Nikiforov and Rousseau
also proved much more general goodness-type results, proving a tight bound on
r(G,H) for several families of sparse graphs G and H as long as |V(G)|<δ|V(H)|
for a small constant δ>0. Using our techniques, we prove a new result of this
type, showing that r(G,H)=(p−1)(n−1)+1 when H=Bk,n and G is a complete p-partite
graph whose first p−1 parts have constant size and whose last part has size δn,
for some small constant δ>0. Again, our proof does not use the regularity method,
and thus yields double-exponential bounds on δ.\r\n"

text: "In 1976, Gallagher showed that the Hardy–Littlewood conjectures on prime
k-tuples imply that the\r\ndistribution of primes in log-size intervals is Poissonian.
He did so by computing average values\r\nof the singular series constants over
different sets of a fixed size k contained in an interval [1,h]\r\nas h → ∞, and
then using this average to compute moments of the distribution of primes. In this\r\npaper,
we study averages where k is relatively large with respect to h. We then apply
these averages\r\nto the tail of the distribution. For example, we show, assuming
appropriate Hardy–Littlewood\r\nconjectures and in certain ranges of the parameters,
the number of intervals [n,n + λlogx] with\r\nn ≤ x containing at least k primes
is ≪ x exp(−k/(λe))."

text: "Anisotropic colloidal particles exhibit complex dynamics which play a crucial
role in their functionality,\r\ntransport, and phase behavior. In this Letter,
we investigate the two-dimensional diffusion of smoothly curved\r\ncolloidal rods—also
known as colloidal bananas—as a function of their opening angle α. We measure
the\r\ntranslational and rotational diffusion coefficients of the particles with
opening angles ranging from 0◦ (straight\r\nrods) to nearly 360◦(closed rings).
In particular, we find that the anisotropic diffusion of the particles varies\r\nnonmonotonically
with their opening angle and that the axis of fastest diffusion switches from
the long to the\r\nshort axis of the particles when α> 180◦. We also find that
the rotational diffusion coefficient of nearly closed\r\nrings is approximately
an order of magnitude higher than that of straight rods of the same length. Finally,
we\r\nshow that the experimental results are consistent with slender body theory,
indicating that the dynamical behavior\r\nof the particles arises primarily from
their local drag anisotropy. These results highlight the impact of curvature\r\non
the Brownian motion of elongated colloidal particles, which must be taken into
account when seeking to\r\nunderstand the behavior of curved colloidal particles."

text: Aromatic side chains are important reporters of the plasticity of proteins,
and often form important contacts in protein--protein interactions. By studying
a pair of structurally homologous cross-β amyloid fibrils, HET-s and HELLF, with
a specific isotope-labeling approach and magic-angle-spinning (MAS) NMR, we have
characterized the dynamic behavior of Phe and Tyr aromatic rings to show that
the hydrophobic amyloid core is rigid, without any sign of "breathing motions"
over hundreds of milliseconds at least. Aromatic residues exposed at the fibril
surface have a rigid ring axis but undergo ring flips, on a variety of time scales
from ns to µs. Our approach provides direct insight into hydrophobic-core motions,
enabling a better evaluation of the conformational heterogeneity generated from
a NMR structural ensemble of such amyloid cross-β architecture.

text: 'Probing the dynamics of aromatic side chains provides important insights
into the behavior of a protein because flips of aromatic rings in a protein’s
hydrophobic core report on breathing motion involving a large part of the protein.
Inherently invisible to crystallography, aromatic motions have been primarily
studied by solution NMR. The question how packing of proteins in crystals affects
ring flips has, thus, remained largely unexplored. Here we apply magic-angle spinning
NMR, advanced phenylalanine 1H-13C/2H isotope labeling and MD simulation to a
protein in three different crystal packing environments to shed light onto possible
impact of packing on ring flips. The flips of the two Phe residues in ubiquitin,
both surface exposed, appear remarkably conserved in the different crystal forms,
even though the intermolecular packing is quite different: Phe4 flips on a ca.
10–20 ns time scale, and Phe45 are broadened in all crystals, presumably due to
µs motion. Our findings suggest that intramolecular influences are more important
for ring flips than intermolecular (packing) effects.'

text: The use of multimodal readout mechanisms next to label-free real-time monitoring
of biomolecular interactions can provide valuable insight into surface-based reaction
mechanisms. To this end, the combination of an electrolyte-gated field-effect
transistor (EG-FET) with a fiber optic-coupled surface plasmon resonance (FO-SPR)
probe serving as gate electrode has been investigated to deconvolute surface mass
and charge density variations associated to surface reactions. However, applying
an electrochemical potential on such gold-coated FO-SPR gate electrodes can induce
gradual morphological changes of the thin gold film, leading to an irreversible
blue-shift of the SPR wavelength and a substantial signal drift. We show that
mild annealing leads to optical and electronic signal stabilization (20-fold lower
signal drift than as-sputtered fiber optic gates) and improved overall analytical
performance characteristics. The thermal treatment prevents morphological changes
of the thin gold-film occurring during operation, hence providing reliable and
stable data immediately upon gate voltage application. Thus, the readout output
of both transducing principles, the optical FO-SPR and electronic EG-FET, stays
constant throughout the whole sensing time-window and the long-term effect of
thermal treatment is also improved, providing stable signals even after 1 year
of storage. Annealing should therefore be considered a necessary modification
for applying fiber optic gate electrodes in real-time multimodal investigations
of surface reactions at the solid-liquid interface.

text: "Data dissemination is a fundamental task in distributed computing. This paper
studies broadcast problems in various innovative models where the communication
network connecting n processes is dynamic (e.g., due to mobility or failures)
and controlled by an adversary. \r\nIn the first model, the processes transitively
communicate their ids in synchronous rounds along a rooted tree given in each
round by the adversary whose goal is to maximize the number of rounds until at
least one id is known by all processes. Previous research has shown a ⌈(3n-1)/2⌉-2
lower bound and an O(nlog log n) upper bound. We show the first linear upper bound
for this problem, namely ⌈(1+√2) n-1⌉ ≈ 2.4n.\r\nWe extend these results to the
setting where the adversary gives in each round k-disjoint forests and their goal
is to maximize the number of rounds until there is a set of k ids such that each
process knows of at least one of them. We give a ⌈3(n-k)/2⌉-1 lower bound and
a (π²+6)/6 n+1 ≈ 2.6n upper bound for this problem.\r\nFinally, we study the setting
where the adversary gives in each round a directed graph with k roots and their
goal is to maximize the number of rounds until there exist k ids that are known
by all processes. We give a ⌈3(n-3k)/2⌉+2 lower bound and a ⌈(1+√2)n⌉+k-1 ≈ 2.4n+k
upper bound for this problem.\r\nFor the two latter problems no upper or lower
bounds were previously known."
