Heat capacity estimators for random series path-integral methods by
finite-difference schemes
Previous heat capacity estimators used in path integral simulations either
have large variances that grow to infinity with the number of path variables or
require the evaluation of first and second order derivatives of the potential.
In the present paper, we show that the evaluation of the total energy by the
T-method estimator and of the heat capacity by the TT-method estimator can be
implemented by a finite difference scheme in a stable fashion. As such, the
variances of the resulting estimators are finite and the evaluation of the
estimators requires the potential function only. By comparison with the task of
computing the partition function, the evaluation of the estimators requires k +
1 times more calls to the potential, where k is the order of the difference
scheme employed. Quantum Monte Carlo simulations for the Ne_13 cluster
demonstrate that a second order central-difference scheme should suffice for
most applications.

On Critical Relative Distance of DNA Codes for Additive Stem Similarity
We consider DNA codes based on the nearest-neighbor (stem) similarity model
which adequately reflects the "hybridization potential" of two DNA sequences.
Our aim is to present a survey of bounds on the rate of DNA codes with respect
to a thermodynamically motivated similarity measure called an additive stem
similarity. These results yield a method to analyze and compare known samples
of the nearest neighbor "thermodynamic weights" associated to stacked pairs
that occurred in DNA secondary structures.

Beyond Explaining: Opportunities and Challenges of XAI-Based Model
Improvement
Explainable Artificial Intelligence (XAI) is an emerging research field
bringing transparency to highly complex and opaque machine learning (ML)
models. Despite the development of a multitude of methods to explain the
decisions of black-box classifiers in recent years, these tools are seldomly
used beyond visualization purposes. Only recently, researchers have started to
employ explanations in practice to actually improve models. This paper offers a
comprehensive overview over techniques that apply XAI practically for improving
various properties of ML models, and systematically categorizes these
approaches, comparing their respective strengths and weaknesses. We provide a
theoretical perspective on these methods, and show empirically through
experiments on toy and realistic settings how explanations can help improve
properties such as model generalization ability or reasoning, among others. We
further discuss potential caveats and drawbacks of these methods. We conclude
that while model improvement based on XAI can have significant beneficial
effects even on complex and not easily quantifyable model properties, these
methods need to be applied carefully, since their success can vary depending on
a multitude of factors, such as the model and dataset used, or the employed
explanation method.

Mass Hierarchies vs. Proton Decay in MSSM Orientifold Compactifications
We review two systematic bottom-up analyses of MSSM quivers recently
performed by the authors. We extend the analysis of arXiv:0905.3379 by
including constraints arising from proton decay via dimension 5 operators and
present all four-stack quivers in the Madrid embedding which satisfy this
additional constraint. Furthermore, we investigate and make precise the
interplay between mass hierarchies obtained via factorizable Yukawa textures
and the presence of dimension 5 proton decay operators in MSSM orientifold
compactifications. We discuss this issue in a five-stack quiver, first
presented in arXiv:0909.4292, which exhibits proper mass hierarchies and no
rapid proton decay.

Surface plasmon-polariton pulses in the form of bright and dark solitons
We consider the linear and nonlinear models of generation of the surface
plasmon-polaritons on the boundary of nonmagnetic dielectric medium and
nonmagnetic metal. We have shown how the three-dimensional incident wave is
transformed to the fluxes of surface plasmon-polaritons at the first and second
harmonics of the TM-mode. These "slow" and "fast" fluxes of the surface
plasmon-polaritons are formed at the both harmonics at the weak interaction. We
obtain that the pulses of surface plasmon-polaritons propagate as the bright
and dark solitons at the strong interaction of the first and second harmonics.

Microscopic analysis of the energy, momentum and spin distributions in a
surface plasmon-polariton wave
We analyze the electromagnetic field near a plane interface between a
conductive and a dielectric media, under conditions supporting surface
plasmon-polariton (SPP) propagation. The conductive medium is described by the
hydrodynamic electron-gas model that enables a consistent analysis of the
field-induced variations of the electron density and velocity at the interface
and its nearest vicinity. The distributions of electromagnetic dynamical
characteristics: energy, energy flow, spin and momentum are calculated
analytically and illustrated numerically, employing silver-vacuum interface as
an example. A set of the "field" and material contributions to the energy, spin
and momentum are explicitly identified and classified with respect to their
physical origins and properties, and the orbital (canonical) and spin
(Belinfante) momentum constituents are separately examined. In this context, a
procedure for the spin-orbital momentum decomposition in the presence of free
charges is proposed and substantiated. The microscopic results agree with the
known phenomenological data but additionally show specific nanoscale structures
in the near-interface behavior of the SPP energy and momentum, which can be
deliberately created, controlled and used in nanotechnology applications.

A Note on the Polytope of Bipartite TSP
The main result of this paper is that the polytope of the bipartite TSP is
significantly different from that of the general TSP. Comb inequalities are
known as facet defining ones in the general case. In the bipartite case,
however, many of them are satisfied whenever all degree and subtour elimination
constraints are satisfied, {\em i.e.}\ these comb inequalities are not facet
defining. The inequalities in question belong to the cases where vertices of
one of the two classes occur in less than the half of the intersections of the
teeth and the hand. Such side conditions are necessary, as simple example shows
that the comb inequality can be violated when each class has vertices in more
than the half of the intersections.

Hipsters and the Cool: A Game Theoretic Analysis of Social Identity,
Trends and Fads
Cultural trends and popularity cycles can be observed all around us, yet our
theories of social influence and identity expression do not explain what
perpetuates these complex, often unpredictable social dynamics. We propose a
theory of social identity expression based on the opposing, but not mutually
exclusive, motives to conform and to be unique among one's neighbors in a
social network. We then model the social dynamics that arise from these
motives. We find that the dynamics typically enter random walks or stochastic
limit cycles rather than converging to a static equilibrium. We also prove that
without social network structure or, alternatively, without the uniqueness
motive, reasonable adaptive dynamics would necessarily converge to equilibrium.
Thus, we show that nuanced psychological assumptions (recognizing preferences
for uniqueness along with conformity) and realistic social network structure
are both necessary for explaining how complex, unpredictable cultural trends
emerge.

Channel capacities via $p$-summing norms
In this paper we show how \emph{the metric theory of tensor products}
developed by Grothendieck perfectly fits in the study of channel capacities, a
central topic in \emph{Shannon's information theory}. Furthermore, in the last
years Shannon's theory has been generalized to the quantum setting to let the
\emph{quantum information theory} step in. In this paper we consider the
classical capacity of quantum channels with restricted assisted entanglement.
In particular these capacities include the classical capacity and the unlimited
entanglement-assisted classical capacity of a quantum channel. To deal with the
quantum case we will use the noncommutative version of $p$-summing maps. More
precisely, we prove that the (product state) classical capacity of a quantum
channel with restricted assisted entanglement can be expressed as the
derivative of a completely $p$-summing norm.

Generating Classes of 3D Virtual Mandibles for AR-Based Medical
Simulation
Simulation and modeling represent promising tools for several application
domains from engineering to forensic science and medicine. Advances in 3D
imaging technology convey paradigms such as augmented reality (AR) and mixed
reality inside promising simulation tools for the training industry. Motivated
by the requirement for superimposing anatomically correct 3D models on a Human
Patient Simulator (HPS) and visualizing them in an AR environment, the purpose
of this research effort is to derive method for scaling a source human mandible
to a target human mandible. Results show that, given a distance between two
same landmarks on two different mandibles, a relative scaling factor may be
computed. Using this scaling factor, results show that a 3D virtual mandible
model can be made morphometrically equivalent to a real target-specific
mandible within a 1.30 millimeter average error bound. The virtual mandible may
be further used as a reference target for registering other anatomical models,
such as the lungs, on the HPS. Such registration will be made possible by
physical constraints among the mandible and the spinal column in the horizontal
normal rest position.

Channel noise induced stochastic facilitation in an auditory brainstem
neuron model
Neuronal membrane potentials fluctuate stochastically due to conductance
changes caused by random transitions between the open and close states of ion
channels. Although it has previously been shown that channel noise can
nontrivially affect neuronal dynamics, it is unknown whether ion-channel noise
is strong enough to act as a noise source for hypothesised noise-enhanced
information processing in real neuronal systems, i.e. 'stochastic
facilitation.' Here, we demonstrate that biophysical models of channel noise
can give rise to two kinds of recently discovered stochastic facilitation
effects in a Hodgkin-Huxley-like model of auditory brainstem neurons. The
first, known as slope-based stochastic resonance (SBSR), enables phasic neurons
to emit action potentials that can encode the slope of inputs that vary slowly
relative to key time-constants in the model. The second, known as inverse
stochastic resonance (ISR), occurs in tonically firing neurons when small
levels of noise inhibit tonic firing and replace it with burst-like dynamics.
Consistent with previous work, we conclude that channel noise can provide
significant variability in firing dynamics, even for large numbers of channels.
Moreover, our results show that possible associated computational benefits may
occur due to channel noise in neurons of the auditory brainstem. This holds
whether the firing dynamics in the model are phasic (SBSR can occur due to
channel noise) or tonic (ISR can occur due to channel noise).

Implications of a Massless Neutralino for Neutrino Physics
We consider the phenomenological implications of a soft SUSY breaking term BN
at the TeV scale (here B is the U(1)_Y gaugino and N is the right-handed
neutrino field). In models with a massless (or nearly massless) neutralino,
such a term will give rise through the see-saw mechanism to new contributions
to the mass matrix of the light neutrinos.
We treat the massless neutralino as an (almost) sterile neutrino and find
that its mass depends on the square of the soft SUSY breaking scale, with
interesting consequences for neutrino physics. We also show that, although it
requires fine-tuning, a massless neutralino in the MSSM or NMSSM is not
experimentally excluded. The implications of this scenario for neutrino physics
are discussed.

Monodromy Conjecture for log generic polynomials
A log generic hypersurface in $\mathbb{P}^n$ with respect to a birational
modification of $\mathbb{P}^n$ is by definition the image of a generic element
of a high power of an ample linear series on the modification. A log
very-generic hypersurface is defined similarly but restricting to line bundles
satisfying a non-resonance condition. Fixing a log resolution of a product
$f=f_1\ldots f_p$ of polynomials, we show that the monodromy conjecture,
relating the motivic zeta function with the complex monodromy, holds for the
tuple $(f_1,\ldots,f_p,g)$ and for the product $fg$, if $g$ is log generic. We
also show that the stronger version of the monodromy conjecture, relating the
motivic zeta function with the Bernstein-Sato ideal, holds for the tuple
$(f_1,\ldots,f_p,g)$ and for the product $fg$, if $g$ is log very-generic.

The behavior of the entanglement entropy in interacting quasi-1D systems
and its consequences for their efficient numerical study
The density matrix renormalization group (DMRG) method allows an efficient
computation of the properties of interacting 1D quantum systems.
Two-dimensional (2D) systems, capable of displaying much richer quantum
behavior, generally lie beyond its reach except for very small system sizes.
Many of the physical properties of 2D systems carry into the quasi-1D case, for
which, unfortunately, the standard 2D DMRG algorithm fares little better. By
finding the form of the entanglement entropy in quasi-1D systems, we directly
identify the reason for this failure. Using this understanding, we explain why
a modified algorithm, capable of cleverly exploiting this behavior of the
entanglement entropy, can accurately reach much larger system sizes. We
demonstrate the power of this method by accurately finding quantum critical
points in frustration induced magnetic transitions, which remain inaccessible
using the standard DMRG or the Monte Carlo methods.

Rings in the Haloes of Planetary Nebulae
We present a search for rings or arcs in the haloes of planetary nebulae
(PNe). We discovered such structures in eight PNe, tripling the sample of PNe
with known rings. This shows that, contrary to what was believed to date, the
occurrence of mass loss fluctuations with timescales of ~100 to ~1000 yrs at
the end of the asymptotic giant branch phase (AGB) is common. We estimate a
lower limit of the occurrence rate of rings in PN haloes to be ~35%.
Using these new detections and the cases previously known, we discuss the
statistical properties of ring systems in PNe haloes. We estimate that the mass
modulation producing the rings takes place during the last 10 or 20 kyrs of AGB
evolution. In PNe, the spacing between rings ranges from <0.01 pc to 0.06 pc,
significantly larger than those seen in proto-PNe. This, together with the
finding of a possible positive correlation of spacing with the post-AGB age of
the nebulae, suggests that the spacing of the rings increases with time.
These properties, as well as the modest surface brightness amplitudes of
rings, are consistent with the predictions of the dust-driven wind instability
model explored by Meijerink et al. (2003), but do not immediately exclude other
proposed models.

Quantum Superposition of Massive Objects and Collapse Models

This consists of coherently expanding the wave function of a

measurement that acts as a double slit, and observing interference after
further evolution. The analysis is performed in a general framework and takes
into account only unavoidable sources of decoherence: blackbody radiation and
scattering of environmental particles. We also discuss the limitations imposed
by the experimental implementation of this protocol using cavity quantum
optomechanics with levitating dielectric nanospheres.

Light variations due to the line-driven wind instability and wind
blanketing in O stars
A small fraction of the radiative flux emitted by hot stars is absorbed by
their winds and redistributed towards longer wavelengths. This effect, which
leads also to the heating of the stellar photosphere, is termed wind
blanketing. For stars with variable winds, the effect of wind blanketing may
lead to the photometric variability. We have studied the consequences of line
driven wind instability and wind blanketing for the light variability of O
stars. We combined the results of wind hydrodynamic simulations and of global
wind models to predict the light variability of hot stars due to the wind
blanketing and instability. The wind instability causes stochastic light
variability with amplitude of the order of tens of millimagnitudes and a
typical timescale of the order of hours for spatially coherent wind structure.
The amplitude is of the order of millimagnitudes when assuming that the wind
consists of large number of independent concentric cones. The variability with
such amplitude is observable using present space borne photometers. We show

Probability Distributions of Positioning Errors for Some Forms of
Center-of-Gravity Algorithms
The center of gravity is a widespread algorithm for position reconstruction
in particle physics. For track fitting, its standard use is always accompanied
by an easy guess for the probability distribution of the positioning errors.
This is an incorrect assumption that degrades the results of the fit. The
explicit error forms show evident Cauchy-(Agnesi) tails that render problematic
the use of variance minimizations. Here, we report the probability
distributions for some combinations of random variables, impossible to find in
literature, but essential for track fitting: $x={\xi}/{(\xi+\eta)}$,
$y={(\xi-\eta)}/[2{(\xi+\eta)}]$, $w=\xi/\eta$, $x=\theta(x_3-x_1)
(-x_3)/(x_3+x_2) +\theta(x_1-x_3)x_1/(x_1+x_2)$ and
$x=(x_1-x_3)/(x_1+x_2+x_3)$. The first three are directly connected to each
other and are partial forms of the two-strip center of gravity. The fourth is
the complete two-strip center of gravity. For its very complex form, it allows
only approximate expressions of the probability. The last expression is a
simplified form of the three-strip center of gravity. General integral forms
are obtained for all of them. Detailed analytical expressions are calculated
assuming $\xi$, $\eta$, $x_1$, $x_2$ and $x_3$ independent random variables
with Gaussian probability distributions (the standard assumption for the strip
noise).

Notes on Dynamics of an External Cavity Semiconductor Lasers
Dynamics of external cavity semiconductor lasers is known to be a complex and
uncontrollable phenomenon. Due to the lack of experimental studies on the
nature of the external cavity semiconductor lasers, there is a need to
theoretically clarify laser dynamics. The stability of laser dynamics in the
present paper, is analyzed through plotting the Lyapunov exponent spectra,
bifurcation diagrams, phase portrait and electric field intensity time series.
The analysis is preformed with respect to applied feedback phase $C_p$,
feedback strength $\eta$ and the pump current of the laser. The main argument
of the paper is to show that the laser dynamics can not be accounted for
through simply a bifurcation diagram and single-control parameter. The
comparison of the obtained results provides a very detailed picture of the
qualitative changes in laser dynamics.

More about QCD on compact spaces
We present some results about spontaneous breaking of global symmetries for
four-flavor, three color QCD on compact spaces with two short directions. When
the two short directions have equal length and identical boundary conditions,
there is a single transition. When the two short directions have boundary
conditions of opposite parity and are of roughly equal extent, the C-breaking
and deconfinement transitions separate. When the two short dimensions are of
different length, the transitions are modified in qualitative agreement with
expectations from dimensional reduction. These features resemble the situation
in pure gauge simulations at small and large number of colors.

Probing new types of $P_c$ states inspired by the interaction between an
$S$-wave charmed baryon and an anticharmed meson in a $\bar T$ doublet state
Inspired by the observations of three $P_c$ states, we systematically
investigate interactions between an $S$-wave charmed baryon
$\mathcal{B}_{c}^{(*)}=\Lambda_c/\Sigma_c/\Sigma_c^{*}$ and an anticharmed
meson $\bar T=\bar D_1/\bar D_2^*$ with the one-pion-exchange potential model
and the one-boson-exchange potential model, and search for possible new types
of $P_c$ states with the structures of $\mathcal{B}_{c}^{(*)}\bar T$. Both
$S$-$D$ wave mixing and coupled channel effects are considered. Our results
suggest that in some $\mathcal{B}_{c}^{(*)}\bar T$ systems there are ideal
candidates of new types of $P_c$ states, i.e., the $\Sigma_c\bar{D}_1$ state
with $I(J^P)=1/2(1/2^+)$, the $\Sigma_c\bar{D}_2^*$ state with
$I(J^P)=1/2(3/2^+)$, the $\Sigma_c^*\bar{D}_1$ state with $I(J^P)=1/2(1/2^+)$,
and the $\Sigma_c^*\bar{D}_2^*$ states with $I(J^P)=1/2(1/2^+, 3/2^+)$, and we
suggest that these predicted new types of $P_c$ states can be detected in the
process $\Lambda_b^0 \to \psi(2S) p \pi^{-}$. Meanwhile, we also extend our
study to the interactions between an $S$-wave charmed baryon and a charmed
meson in a $T$ doublet, and we predict a series of double-charm molecular
pentaquarks.

Atmospheric pressure dependance of HAWC scaler system
The variation in atmospheric pressure is due to changes in mass of the air
column above, which in turn resembles the density variation of atmosphere and
will affect the decay of secondary particles of cosmic rays. The ground based
cosmic ray detectors observe pressure dependent variation in their flux. The
High Altitude Water Cherenkov (HAWC) gamma ray observatory is a great detector
of secondary particles because of its high altitude, high uptime, and large
area (including total photo-cathode area), which makes the HAWC scaler system
an ideal instrument for solar modulation studies. Although, in order to perform
these studies it is necessary to isolate and remove the atmospheric
modulations. The observed rate in each PMT has signatures of both the solar and
atmospheric modulations, which makes it difficult to measure the pressure
coefficient ($\beta_P$ ). The pressure at the HAWC site shows a periodic
behavior ($\sim$ 12 hours), which also reflects in the scalar rates. This
periodic property was used to isolate the pressure modulation and $\beta_P$
were estimated with accuracy. Since the pressure dependence is a physical
phenomenon, the estimated coefficients for PMTs should be identical, any
deviation from this can be due to malfunction of the PMT. This make this method
a useful tool to identify the malfunctioning PMTs and help us to isolate them
from the analysis. In this analysis we are presenting the method of estimation
of the pressure coefficients and its usage to correct the HAWC scalar data to
make it suitable for the solar modulations studies.

Vote Delegation with Unknown Preferences
We examine vote delegation when preferences of agents are private
information. One group of agents (delegators) does not want to participate in
voting and abstains under conventional voting or can delegate its votes to the
other group (voters) who decide between two alternatives. We show that free
delegation favors minorities, that is, alternatives that have a lower chance of
winning ex-ante. The same occurs if the number of voting rights that actual
voters can have is capped. When the number of delegators increases, the
probability that the ex-ante minority wins under free and capped delegation
converges to the one under conventional voting--albeit non-monotonically. Our
results are obtained in a private value setting but can be readily translated
into an information aggregation setting when voters receive a signal about the
''correct" alternative with some probability.

Mechanical Behaviour of Glasses and Amorphous Materials
A wide range of materials can exist in microscopically disordered solid
forms, referred to as amorphous solids or glasses. Such materials -- oxide
glasses and metallic glasses, to polymer glasses, and soft solids such as
colloidal glasses, emulsions and granular packings -- are useful as structural
materials in a variety of contexts. Their deformation and flow behaviour is
relevant for many others. Apart from fundamental questions associated with the
formation of these solids, comprehending their mechanical behaviour is thus of
interest, and of significance for their use as materials. In particular, the
nature of plasticity and yielding behaviour in amorphous solids has been
actively investigated. Different amorphous solids exhibit behaviour that is
apparently diverse and qualitatively different from those of crystalline
materials. A goal of recent investigations has been to comprehend the unifying
characteristics of amorphous plasticity and to understand the apparent
differences among them. We summarise some of the recent progress in this
direction. We focus on insights obtained from computer simulation studies, and
in particular those employing oscillatory shear deformation of model glasses.

IntentNet: Learning to Predict Intention from Raw Sensor Data
In order to plan a safe maneuver, self-driving vehicles need to understand

that exploits both 3D point clouds produced by a LiDAR sensor as well as
dynamic maps of the environment. Our multi-task model achieves better accuracy
than the respective separate modules while saving computation, which is
critical to reducing reaction time in self-driving applications.

Connections on modules over quasi-homogeneous plane curves
Let k be an algebraically closed field of characteristic 0, and let $A =
k[x,y]/(f)$ be a quasi-homogeneous plane curve. We show that for any graded
torsion free A-module M, there exists a natural graded integrable connection,
i.e. a graded A-linear homomorphism $\nabla: \operatorname{Der}_k(A) \to
\operatorname{End}_k(M)$ that satisfy the derivation property and preserves the
Lie product.
In particular, a torsion free module N over the complete local ring $B = \hat
A$ admits a natural integrable connection if A is a simple curve singularity,
or if A is irreducible and N is a gradable module.

Generalized Hermite processes, discrete chaos and limit theorems
We introduce a broad class of self-similar processes $\{Z(t),t\ge 0\}$ called
generalized Hermite process. They have stationary increments, are defined on a
Wiener chaos with Hurst index $H\in (1/2,1)$, and include Hermite processes as
a special case. They are defined through a homogeneous kernel $g$, called
"generalized Hermite kernel", which replaces the product of power functions in
the definition of Hermite processes. The generalized Hermite kernels $g$ can
also be used to generate long-range dependent stationary sequences forming a
discrete chaos process $\{X(n)\}$. In addition, we consider a
fractionally-filtered version $Z^\beta(t)$ of $Z(t)$, which allows $H\in
(0,1/2)$. Corresponding non-central limit theorems are established. We also
give a multivariate limit theorem which mixes central and non-central limit
theorems.

Quantum supremacy with spin squeezed atomic ensembles
We propose a method to achieve quantum supremacy using ensembles of qubits,
using only spin squeezing, basis rotations, and Fock state measurements. Each
ensemble is assumed to be controllable only with its total spin. Using a
repeated sequence of random basis rotations followed by squeezing, we show that
the probability distribution of the final measurements quickly approaches a
Porter-Thomas distribution. We show that the sampling probability can be
related to a #P-hard problem with a complexity scaling as $(N+1)^M$, where $N$
is the number of qubits in an ensemble and $ M $ is the number of ensembles.
The scheme can be implemented with hot or cold atomic ensembles. Due to the
large number of atoms in typical atomic ensembles, this allows access to the
quantum supremacy regime with a modest number of ensembles or gate depth.

Korselt Rational Bases of Prime Powers
Let $N$ be a positive integer, $\mathbb{A}$ be a subset of $\mathbb{Q}$ and
$\alpha=\dfrac{\alpha_{1}}{\alpha_{2}}\in \mathbb{A}\setminus \{0,N\}$. $N$ is
called an $\alpha$-Korselt number (equivalently $\alpha$ is said an $N$-Korselt
base) if $\alpha_{2}p-\alpha_{1}$ divides $\alpha_{2}N-\alpha_{1}$ for every
prime divisor $p$ of $N$. By the Korselt set of $N$ over $\mathbb{A}$, we mean
the set $\mathbb{A}$-$\mathcal{KS}(N)$ of all $\alpha\in \mathbb{A}\setminus
\{0,N\}$ such that $N$ is an $\alpha$-Korselt number. In this paper we
determine explicitly for a given prime number $q$ and an integer $l\in
\mathbb{N}\setminus \{0,1\}$, the set $\mathbb{Q}$-$\mathcal{KS}(q^{l})$ and we
establish some connections between the $q^{l}$-Korselt bases in $\mathbb{Q}$
and others in $\mathbb{Z}$. The case of $\mathbb{A}=\mathbb{Q}\cap[-1,1[$ is
studied where we prove that $(\mathbb{Q}\cap[-1,1[)$-$\mathcal{KS}(q^{l})$ is
empty if and only if $l=2$. Moreover, we show that each nonzero rational
$\alpha$ is an $N$-Korselt base for infinitely many numbers $N=q^{l}$ where $q$
is a prime number and $l\in\mathbb{N}$.

The growth of typical star-forming galaxies and their super massive
black holes across cosmic time since z~2
Understanding galaxy formation and evolution requires studying the interplay
between the growth of galaxies and the growth of their black holes across
cosmic time. Here we explore a sample of Ha-selected star-forming galaxies from
the HiZELS survey and use the wealth of multi-wavelength data in the COSMOS
field (X-rays, far-infrared and radio) to study the relative growth rates
between typical galaxies and their central supermassive black holes, from
z=2.23 to z=0. Typical star-forming galaxies at z~1-2 have black hole accretion
rates (BHARs) of 0.001-0.01 Msun/yr and star formation rates (SFRs) of ~10-40
Msun/yr, and thus grow their stellar mass much quicker than their black hole
mass (~3.3 orders of magnitude faster). However, ~3% of the sample (the sources
detected directly in the X-rays) show a significantly quicker growth of the
black hole mass (up to 1.5 orders of magnitude quicker growth than the typical
sources). BHARs fall from z=2.23 to z=0, with the decline resembling that of
star formation rate density or the typical SFR. We find that the average black
hole to galaxy growth (BHAR/SFR) is approximately constant for star-forming
galaxies in the last 11 Gyrs. The relatively constant BHAR/SFR suggests that
these two quantities evolve equivalently through cosmic time and with
practically no delay between the two.

Spontaneous Motion on Two-dimensional Continuous Attractors
Attractor models are simplified models used to describe the dynamics of
firing rate profiles of a pool of neurons. The firing rate profile, or the
neuronal activity, is thought to carry information. Continuous attractor neural
networks (CANNs) describe the neural processing of continuous information such
as object position, object orientation and direction of object motion.
Recently, it was found that, in one-dimensional CANNs, short-term synaptic
depression can destabilize bump-shaped neuronal attractor activity profiles. In
this paper, we study two-dimensional CANNs with short-term synaptic depression
and with spike frequency adaptation. We found that the dynamics of CANNs with
short-term synaptic depression and CANNs with spike frequency adaptation are
qualitatively similar. We also found that in both kinds of CANNs the
perturbative approach can be used to predict phase diagrams, dynamical
variables and speed of spontaneous motion.

Bloch-Siegert Shift in a Hybrid Quantum Register: Quantification and
Compensation
Quantum registers that combine the attractive properties of different types
of qubits are useful for many different applications. They also pose a number
of challenges, often associated with the large differences in coupling
strengths between the different types of qubits. One example is the
non-resonant effect that alternating electromagnetic fields have on the
transitions of qubits that are not targeted by the specific gate operation. The
example being studied here is known as Bloch-Siegert shift. Unless these shifts
are accounted for and, if possible, compensated, they can completely destroy
the information contained in the quantum register. Here we study this effect
quantitatively in the important example of the nitrogen vacancy (NV) center in
diamond and demonstrate how it can be eliminated.

A search for an unexpected asymmetry in the production of $e^+ \mu^-$

This search, a type not previously performed at ATLAS, uses a comparison of
the production cross sections for $e^+ \mu^-$ and $e^- \mu^+$ pairs to
constrain physics processes beyond the Standard Model. It uses $139
\text{fb}^{-1}$ of proton$-$proton collision data recorded at $\sqrt{s} = 13$
TeV at the LHC. Targeting sources of new physics which prefer final states
containing $e^{+}\mu^{-}$ to $e^{-}\mu^{+}$, the search contains two broad
signal regions which are used to provide model-independent constraints on the
ratio of cross sections at the 2% level. The search also has two special
selections targeting supersymmetric models and leptoquark signatures.
Observations using one of these selections are able to exclude, at 95%
confidence level, singly produced smuons with masses up to 640 GeV in a model
in which the only other light sparticle is a neutralino when the
$R$-parity-violating coupling $\lambda'_{231}$ is close to unity. Observations
using the other selection exclude scalar leptoquarks with masses below 1880 GeV
when $g_{\text{1R}}^{eu}=g_{\text{1R}}^{\mu c}=1$, at 95% confidence level. The
limit on the coupling reduces to $g_{\text{1R}}^{eu}=g_{\text{1R}}^{\mu
c}=0.46$ for a mass of 1420 GeV.

Anomalous c-axis charge dynamics in copper oxide materials
Within the t-J model, the c-axis charge dynamics of the copper oxide
materials in the underdoped and optimally doped regimes is studied by
considering the incoherent interlayer hopping. It is shown that the c-axis
charge dynamics is mainly governed by the scattering from the in-plane
fluctuation. In the optimally doped regime, the c-axis resistivity is a linear
in temperatures, and shows the metallic-like behavior for all temperatures,
while the c-axis resistivity in the underdoped regime is characterized by a
crossover from the high temperature metallic-like behavior to the low
temperature semiconducting-like behavior, which are consistent with experiments
and numerical simulations.

conjecture due to Hausel, that is, the pure parts of the mixed Hodge structures
of the character variety is isomorphic to the ordinary rational cohomology
groups of the quiver variety of type $\boldsymbol{\mu}$.

Towards Molecular Simulations that are Transparent, Reproducible, Usable
By Others, and Extensible (TRUE)
Systems composed of soft matter (e.g., liquids, polymers, foams, gels,
colloids, and most biological materials) are ubiquitous in science and
engineering, but molecular simulations of such systems pose particular
computational challenges, requiring time and/or ensemble-averaged data to be
collected over long simulation trajectories for property evaluation. Performing
a molecular simulation of a soft matter system involves multiple steps, which
have traditionally been performed by researchers in a "bespoke" fashion,
resulting in many published soft matter simulations not being reproducible
based on the information provided in the publications. To address the issue of
reproducibility and to provide tools for computational screening, we have been
developing the open-source Molecular Simulation and Design Framework (MoSDeF)
software suite. In this paper, we propose a set of principles to create
Transparent, Reproducible, Usable by others, and Extensible (TRUE) molecular
simulations. MoSDeF facilitates the publication and dissemination of TRUE
simulations by automating many of the critical steps in molecular simulation,
thus enhancing their reproducibility. We provide several examples of TRUE
molecular simulations: All of the steps involved in creating, running and
extracting properties from the simulations are distributed on open-source
platforms (within MoSDeF and on GitHub), thus meeting the definition of TRUE
simulations.

Discovering new worlds: a review of signal processing methods for
detecting exoplanets from astronomical radial velocity data
Exoplanets, short for `extra solar planets', are planets outside our solar
system. They are objects with masses less than around 15 Jupiter-masses that
orbit stars other than the Sun. They are small enough so they can not burn
deuterium in their cores, yet large enough that they are not so called `dwarf
planets' like Pluto.
To discover life elsewhere in the universe, particularly outside our own
solar system, a good starting point would be to search for planets orbiting
nearby Sun-like stars, since the only example of life we know of thrives on a
planet we call Earth that orbits a G-type dwarf star. Furthermore,
understanding the population of exoplanetary systems in the nearby solar
neighbourhood allows us to understand the mechanisms that built our own solar
system and gave rise to the conditions necessary for our tree of life to
flourish.
Signal processing is an integral part of exoplanet detection. From improving
the signal-to-noise ratio of the observed data to applying advanced statistical
