text: We demonstrate that releasing atoms into free space from an optical lattice
does not deteriorate cavity-generated spin squeezing for metrological purposes.
In this work, an ensemble of 500000 spin-squeezed atoms in a high-finesse optical
cavity with near-uniform atom-cavity coupling is prepared, released into free
space, recaptured in the cavity, and probed. Up to ∼10 dB of metrologically relevant
squeezing is retrieved for 700μs free-fall times, and decaying levels of squeezing
are realized for up to 3 ms free-fall times. The degradation of squeezing results
from loss of atom-cavity coupling homogeneity between the initial squeezed state
generation and final collective state readout. A theoretical model is developed
to quantify this degradation and this model is experimentally validated.

text: Mechanistic modeling in neuroscience aims to explain observed phenomena in
terms of underlying causes. However, determining which model parameters agree
with complex and stochastic neural data presents a significant challenge. We address
this challenge with a machine learning tool which uses deep neural density estimators—trained
using model simulations—to carry out Bayesian inference and retrieve the full
space of parameters compatible with raw data or selected data features. Our method
is scalable in parameters and data features and can rapidly analyze new data after
initial training. We demonstrate the power and flexibility of our approach on
receptive fields, ion channels, and Hodgkin–Huxley models. We also characterize
the space of circuit configurations giving rise to rhythmic activity in the crustacean
stomatogastric ganglion, and use these results to derive hypotheses for underlying
compensation mechanisms. Our approach will help close the gap between data-driven
and theory-driven models of neural dynamics.

text: We introduce a graph Ramsey game called Ramsey, Paper,Scissors. This game
has two players, Proposer and Decider.Starting from an empty graph on n vertices,
on each turnProposer proposes a potential edge and Decider simultane-ously decides
(without knowing Proposer’s choice) whether toadd it to the graph. Proposer cannot
propose an edge whichwould create a triangle in the graph. The game ends whenProposer
has no legal moves remaining, and Proposer wins ifthe final graph has independence
number at least s. We provea threshold phenomenon exists for this game by exhibitingrandomized
strategies for both players that are optimal up toconstants. Namely, there exist
constants 0 < A < B such that(under optimal play) Proposer wins with high probability
ifs < A√n log n, while Decider wins with high probability ifs > B√n log n. This
is a factor of Θ(√log n)) larger than thelower bound coming from the off-diagonal
Ramsey numberr(3, s).

text: Understanding the impact of curvature on the self-assembly of elongated microscopic
building blocks, such as molecules and proteins, is key to engineering functional
materials with predesigned structure. We develop model “banana-shaped” colloidal
particles with tunable dimensions and curvature, whose structure and dynamics
are accessible at the particle level. By heating initially straight rods made
of SU-8 photoresist, we induce a controllable shape deformation that causes the
rods to buckle into banana-shaped particles. We elucidate the phase behavior of
differently curved colloidal bananas using confocal microscopy. Although highly
curved bananas only form isotropic phases, less curved bananas exhibit very rich
phase behavior, including biaxial nematic phases, polar and antipolar smectic-like
phases, and even the long-predicted, elusive splay-bend nematic phase.

text: Nanomaterials produced from the bottom-up assembly of nanocrystals may incorporate
∼1020–1021 cm–3 not fully coordinated surface atoms, i.e., ∼1020–1021 cm–3 potential
donor or acceptor states that can strongly affect transport properties. Therefore,
to exploit the full potential of nanocrystal building blocks to produce functional
nanomaterials and thin films, a proper control of their surface chemistry is required.
Here, we analyze how the ligand stripping procedure influences the charge and
heat transport properties of sintered PbSe nanomaterials produced from the bottom-up
assembly of colloidal PbSe nanocrystals. First, we show that the removal of the
native organic ligands by thermal decomposition in an inert atmosphere leaves
relatively large amounts of carbon at the crystal interfaces. This carbon blocks
crystal growth during consolidation and at the same time hampers charge and heat
transport through the final nanomaterial. Second, we demonstrate that, by stripping
ligands from the nanocrystal surface before consolidation, nanomaterials with
larger crystal domains, lower porosity, and higher charge carrier concentrations
are obtained, thus resulting in nanomaterials with higher electrical and thermal
conductivities. In addition, the ligand displacement leaves the nanocrystal surface
unprotected, facilitating oxidation and chalcogen evaporation. The influence of
the ligand displacement on the nanomaterial charge transport properties is rationalized
here using a two-band model based on the standard Boltzmann transport equation
with the relaxation time approximation. Finally, we present an application of
the produced functional nanomaterials by modeling, fabricating, and testing a
simple PbSe-based thermoelectric device with a ring geometry.

text: The plant hormone auxin plays indispensable roles in plant growth and development.
An essential level of regulation in auxin action is the directional auxin transport
within cells. The establishment of auxin gradient in plant tissue has been attributed
to local auxin biosynthesis and directional intercellular auxin transport, which
both are controlled by various environmental and developmental signals. It is
well established that asymmetric auxin distribution in cells is achieved by polarly
localized PIN-FORMED (PIN) auxin efflux transporters. Despite the initial insights
into cellular mechanisms of PIN polarization obtained from the last decades, the
molecular mechanism and specific regulators mediating PIN polarization remains
elusive. In this thesis, we aim to find novel players in PIN subcellular polarity
regulation during Arabidopsis development. We first characterize the physiological
effect of piperonylic acid (PA) on Arabidopsis hypocotyl gravitropic bending and
PIN polarization. Secondly, we reveal the importance of SCFTIR1/AFB auxin signaling
pathway in shoot gravitropism bending termination. In addition, we also explore
the role of myosin XI complex, and actin cytoskeleton in auxin feedback regulation
on PIN polarity. In Chapter 1, we give an overview of the current knowledge about
PIN-mediated auxin fluxes in various plant tropic responses. In Chapter 2, we
study the physiological effect of PA on shoot gravitropic bending. Our results
show that PA treatment inhibits auxin-mediated PIN3 repolarization by interfering
with PINOID and PIN3 phosphorylation status, ultimately leading to hyperbending
hypocotyls. In Chapter 3, we provide evidence to show that the SCFTIR1/AFB nuclear
auxin signaling pathway is crucial and required for auxin-mediated PIN3 repolarization
and shoot gravitropic bending termination. In Chapter 4, we perform a phosphoproteomics
approach and identify the motor protein Myosin XI and its binding protein, the
MadB2 family, as an essential regulator of PIN polarity for auxin-canalization
related developmental processes. In Chapter 5, we demonstrate the vital role of
actin cytoskeleton in auxin feedback on PIN polarity by regulating PIN subcellular
trafficking. Overall, the data presented in this PhD thesis brings novel insights
into the PIN polar localization regulation that resulted in the (re)establishment
of the polar auxin flow and gradient in response to environmental stimuli during
plant development.

text: "Reverse firewalls were introduced at Eurocrypt 2015 by Miro-nov and Stephens-Davidowitz,
as a method for protecting cryptographic protocols against attacks on the devices
of the honest parties. In a nutshell: a reverse firewall is placed outside of
a device and its goal is to “sanitize” the messages sent by it, in such a way
that a malicious device cannot leak its secrets to the outside world. It is typically
assumed that the cryptographic devices are attacked in a “functionality-preserving
way” (i.e. informally speaking, the functionality of the protocol remains unchanged
under this attacks). In their paper, Mironov and Stephens-Davidowitz construct
a protocol for passively-secure two-party computations with firewalls, leaving
extension of this result to stronger models as an open question.\r\nIn this paper,
we address this problem by constructing a protocol for secure computation with
firewalls that has two main advantages over the original protocol from Eurocrypt
2015. Firstly, it is a multiparty computation protocol (i.e. it works for an arbitrary
number n of the parties, and not just for 2). Secondly, it is secure in much stronger
corruption settings, namely in the active corruption model. More precisely: we
consider an adversary that can fully corrupt up to \U0001D45B−1 parties, while
the remaining parties are corrupt in a functionality-preserving way.\r\nOur core
techniques are: malleable commitments and malleable non-interactive zero-knowledge,
which in particular allow us to create a novel protocol for multiparty augmented
coin-tossing into the well with reverse firewalls (that is based on a protocol
of Lindell from Crypto 2001)."

text: "Balanced search trees typically use key comparisons to guide their operations,
and achieve logarithmic running time. By relying on numerical properties of the
keys, interpolation search achieves lower search complexity and better performance.
Although interpolation-based data structures were investigated in the past, their
non-blocking concurrent variants have received very little attention so far.\r\nIn
this paper, we propose the first non-blocking implementation of the classic interpolation
search tree (IST) data structure. For arbitrary key distributions, the data structure
ensures worst-case O(log n + p) amortized time for search, insertion and deletion
traversals. When the input key distributions are smooth, lookups run in expected
O(log log n + p) time, and insertion and deletion run in expected amortized O(log
log n + p) time, where p is a bound on the number of threads. To improve the scalability
of concurrent insertion and deletion, we propose a novel parallel rebuilding technique,
which should be of independent interest.\r\nWe evaluate whether the theoretical
improvements translate to practice by implementing the concurrent interpolation
search tree, and benchmarking it on uniform and nonuniform key distributions,
for dataset sizes in the millions to billions of keys. Relative to the state-of-the-art
concurrent data structures, the concurrent interpolation search tree achieves
performance improvements of up to 15% under high update rates, and of up to 50%
under moderate update rates. Further, ISTs exhibit up to 2X less cache-misses,
and consume 1.2 -- 2.6X less memory compared to the next best alternative on typical
dataset sizes. We find that the results are surprisingly robust to distributional
skew, which suggests that our data structure can be a promising alternative to
classic concurrent search structures."

text: Temporally organized reactivation of experiences during awake immobility periods
is thought to underlie cognitive processes like planning and evaluation. While
replay of trajectories is well established for the hippocampus, it is unclear
whether the medial prefrontal cortex (mPFC) can reactivate sequential behavioral
experiences in the awake state to support task execution. We simultaneously recorded
from hippocampal and mPFC principal neurons in rats performing a mPFC-dependent
rule-switching task on a plus maze. We found that mPFC neuronal activity encoded
relative positions between the start and goal. During awake immobility periods,
the mPFC replayed temporally organized sequences of these generalized positions,
resembling entire spatial trajectories. The occurrence of mPFC trajectory replay
positively correlated with rule-switching performance. However, hippocampal and
mPFC trajectory replay occurred independently, indicating different functions.
These results demonstrate that the mPFC can replay ordered activity patterns representing
generalized locations and suggest that mPFC replay might have a role in flexible
behavior.

text: We present the first deterministic wait-free long-lived snapshot algorithm,
using only read and write operations, that guarantees polylogarithmic amortized
step complexity in all executions. This is the first non-blocking snapshot algorithm,
using reads and writes only, that has sub-linear amortized step complexity in
executions of arbitrary length. The key to our construction is a novel implementation
of a 2-component max array object which may be of independent interest.

text: 'We present a unified framework tackling two problems: class-specific 3D reconstruction
from a single image, and generation of new 3D shape samples. These tasks have
received considerable attention recently; however, most existing approaches rely
on 3D supervision, annotation of 2D images with keypoints or poses, and/or training
with multiple views of each object instance. Our framework is very general: it
can be trained in similar settings to existing approaches, while also supporting
weaker supervision. Importantly, it can be trained purely from 2D images, without
pose annotations, and with only a single view per instance. We employ meshes as
an output representation, instead of voxels used in most prior work. This allows
us to reason over lighting parameters and exploit shading information during training,
which previous 2D-supervised methods cannot. Thus, our method can learn to generate
and reconstruct concave object classes. We evaluate our approach in various settings,
showing that: (i) it learns to disentangle shape from pose and lighting; (ii)
using shading in the loss improves performance compared to just silhouettes; (iii)
when using a standard single white light, our model outperforms state-of-the-art
2D-supervised methods, both with and without pose supervision, thanks to exploiting
shading cues; (iv) performance improves further when using multiple coloured lights,
even approaching that of state-of-the-art 3D-supervised methods; (v) shapes produced
by our model capture smooth surfaces and fine details better than voxel-based
approaches; and (vi) our approach supports concave classes such as bathtubs and
sofas, which methods based on silhouettes cannot learn.'

text: 'The superconducting circuit community has recently discovered the promising
potential of superinductors. These circuit elements have a characteristic impedance
exceeding the resistance quantum RQ ≈ 6.45 kΩ which leads to a suppression of
ground state charge fluctuations. Applications include the realization of hardware
protected qubits for fault tolerant quantum computing, improved coupling to small
dipole moment objects and defining a new quantum metrology standard for the ampere.
In this work we refute the widespread notion that superinductors can only be implemented
based on kinetic inductance, i.e. using disordered superconductors or Josephson
junction arrays. We present modeling, fabrication and characterization of 104
planar aluminum coil resonators with a characteristic impedance up to 30.9 kΩ
at 5.6 GHz and a capacitance down to ≤ 1 fF, with lowloss and a power handling
reaching 108 intra-cavity photons. Geometric superinductors are free of uncontrolled
tunneling events and offer high reproducibility, linearity and the ability to
couple magnetically - properties that significantly broaden the scope of future
quantum circuits. '

text: For complex Wigner-type matrices, i.e. Hermitian random matrices with independent,
not necessarily identically distributed entries above the diagonal, we show that
at any cusp singularity of the limiting eigenvalue distribution the local eigenvalue
statistics are universal and form a Pearcey process. Since the density of states
typically exhibits only square root or cubic root cusp singularities, our work
complements previous results on the bulk and edge universality and it thus completes
the resolution of the Wigner–Dyson–Mehta universality conjecture for the last
remaining universality type in the complex Hermitian class. Our analysis holds
not only for exact cusps, but approximate cusps as well, where an extended Pearcey
process emerges. As a main technical ingredient we prove an optimal local law
at the cusp for both symmetry classes. This result is also the key input in the
companion paper (Cipolloni et al. in Pure Appl Anal, 2018. arXiv:1811.04055) where
the cusp universality for real symmetric Wigner-type matrices is proven. The novel
cusp fluctuation mechanism is also essential for the recent results on the spectral
radius of non-Hermitian random matrices (Alt et al. in Spectral radius of random
matrices with independent entries, 2019. arXiv:1907.13631), and the non-Hermitian
edge universality (Cipolloni et al. in Edge universality for non-Hermitian random
matrices, 2019. arXiv:1908.00969).

text: We prove edge universality for a general class of correlated real symmetric
or complex Hermitian Wigner matrices with arbitrary expectation. Our theorem also
applies to internal edges of the self-consistent density of states. In particular,
we establish a strong form of band rigidity which excludes mismatches between
location and label of eigenvalues close to internal edges in these general models.

text: 'We address the following question: How redundant is the parameterisation
of ReLU networks? Specifically, we consider transformations of the weight space
which leave the function implemented by the network intact. Two such transformations
are known for feed-forward architectures: permutation of neurons within a layer,
and positive scaling of all incoming weights of a neuron coupled with inverse
scaling of its outgoing weights. In this work, we show for architectures with
non-increasing widths that permutation and scaling are in fact the only function-preserving
weight transformations. For any eligible architecture we give an explicit construction
of a neural network such that any other network that implements the same function
can be obtained from the original one by the application of permutations and rescaling. The
proof relies on a geometric understanding of boundaries between linear regions
of ReLU networks, and we hope the developed mathematical tools are of independent
interest.'

text: AbstractClimate impact studies often require
climate data at a higher space–time resolution than is available from global and
regional climate models. Weather generator (WG) models, generally designed for
mesoscale applications (e.g., 101–105
km2), are popular and widely used tools to downscale climate
data to finer resolution. One advantage of using WGs is their ability to generate
the necessary climate variables for impact studies in data sparse regions. In
this study, we evaluate the ability of a previously established state of the art
WG (the AWE‐GEN‐2d model) to perform in data sparse regions that are beyond the
mesoscale, using the Zambezi River basin (106 km2)
in southeast Africa as a case study. The AWE‐GEN‐2d model was calibrated using
data from satellite retrievals and climate re‐analysis products in place of the
absent observational data. An 8‐km climate ensemble at hourly resolution, covering
the period of 1976–2099 (present climate and RCP4.5 emission scenario from 2020),
was then simulated. Using the simulated 30‐member ensemble, climate indices for
both present and future climates were computed. The high‐resolution climate indices
allow detailed analysis of the effects of climate change on different areas within
the basin. For example, the southwestern area of the basin is predicted to experience
the greatest change due to increased temperature, while the southeastern area
was found to be already so hot that is less affected (e.g., the number of 'very
hot days' per year increase by 18 and 9 days, respectively). Rainfall intensities
are found to increase most in the eastern areas of the basin (1 mm·d−1)
in comparison to the western region (0.3 mm·d−1). As demonstrated
in this study, AWE‐GEN‐2d can be calibrated successfully using data from climate
reanalysis products in the absence of ground station data and can be applied at
larger scales than the mesoscale.
