We consider dynamical systems on the space of functions taking values in a
free associative algebra. The system is said to be integrable if it possesses
an infinite dimensional Lie algebra of commuting symmetries. In this paper we
propose a new approach to the problem of quantisation of dynamical systems,
introduce t... |
The {\it straight-through estimator} (STE) is commonly used to optimize
quantized neural networks, yet its contexts of effective performance are still
unclear despite empirical successes.To make a step forward in this
comprehension, we apply STE to a well-understood problem: {\it sparse support
recovery}. We introduc... |
Designing coherent processes is essential for developing quantum information
technologies. We study coherent dynamics of two spatially separated electrons
in a coupled semiconductor double quantum dot (DQD), in which various two-qubit
operations are demonstrated just by adjusting the gate voltages. Especially,
second... |
We exhibit a convex polynomial optimization problem for which the
diagonally-dominant sum-of-squares (DSOS) and the scaled diagonally-dominant
sum-of-squares (SDSOS) hierarchies, based on linear programming and
second-order conic programming respectively, do not converge to the global
infimum. The same goes for the r... |
Policy gradient methods in actor-critic reinforcement learning (RL) have
become perhaps the most promising approaches to solving continuous optimal
control problems. However, the trial-and-error nature of RL and the inherent
randomness associated with solution approximations cause variations in the
learned optimal va... |
When agents interact socially with different intentions, conflicts are
difficult to avoid. Although how agents can resolve such problems autonomously
has not been determined, dynamic characteristics of agency may shed light on
underlying mechanisms. The current study focused on the sense of agency (SoA),
a specific a... |
Oxide interfaces exhibit a broad range of physical effects stemming from
broken inversion symmetry. In particular, they can display non-reciprocal
phenomena when time reversal symmetry is also broken, e.g., by the application
of a magnetic field. Examples include the direct and inverse Edelstein effects
(DEE, IEE) th... |
Precision tests of the Standard Model and searches for beyond the Standard
Model physics often require nuclear structure input. There has been a
tremendous progress in the development of nuclear ab initio techniques capable
of providing accurate nuclear wave functions. For the calculation of

We solve closed string theory in all regular homogeneous plane-wave
backgrounds with homogeneous NS three-form field strength and a dilaton. The
parameters of the model are constant symmetric and anti-symmetric matrices
k_{ij} and f_{ij} associated with the metric, and a constant anti-symmetric
matrix h_{ij} associat... |
Price of anarchy quantifies the degradation of social welfare in games due to
the lack of a centralized authority that can enforce the optimal outcome. At
its antipodes, mechanism design studies how to ameliorate these effects by
incentivizing socially desirable behavior and implementing the optimal state as

We derive eigenvalue bounds for the $t$-distance chromatic number of a graph,
which is a generalization of the classical chromatic number. We apply such
bounds to hypercube graphs, providing alternative spectral proofs for results

for severa... |
The in vitro and in vivo activity of diminazene (Dim), artesunate (Art) and
combination of Dim and Art (Dim-Art) against Leishmania donovani was compared

We construct a stable formal model of a Lubin-Tate curve with level three,
and study the action of a Weil group and a division algebra on its stable
reduction. Further, we study a structure of cohomology of the Lubin-Tate curve.
Our study is purely local and includes the case where the characteristic of the
residue f... |
Exciton dynamics can be strongly affected by lattice vibrations through
electron-phonon coupling. This is rarely explored in two-dimensional magnetic
semiconductors. Focusing on bilayer CrI3, we first show the presence of strong
electron-phonon coupling through temperature-dependent photoluminescence and
absorption s... |
Friedland (1981) showed that for a nonnegative square matrix A, the spectral
radius r(e^D A) is a log-convex functional over the real diagonal matrices D.
He showed that for fully indecomposable A, log r(e^D A) is strictly convex over
D_1, D_2 if and only if D_1-D_2 != c I for any c \in R. Here the condition of

We investigate the solvability of the Byzantine Reliable Broadcast and
Byzantine Broadcast Channel problems in distributed systems affected by Mobile

In this paper, a new gradient-based optimization approach by automatically

HI intensity mapping (IM) is a novel technique capable of mapping the
large-scale structure of the Universe in three dimensions and delivering
exquisite constraints on cosmology, by using HI as a biased tracer of the dark
matter density field. This is achieved by measuring the intensity of the
redshifted 21cm line ov... |
A model of the ferromagnetic origin of magnetic fields of neutron stars is
considered. In this model, the magnetic phase transition occurs inside the core
of neutron stars soon after formation. However, owing to the high electrical

various r... |
Let $M$ be a hyperkahler manifold of maximal holonomy (that is, an IHS
manifold), and let $K$ be its Kahler cone, which is an open, convex subset in
the space $H^{1,1}(M, R)$ of real (1,1)-forms. This space is equipped with a
canonical bilinear symmetric form of signature $(1,n)$ obtained as a

polarized Z i... |
In this paper linear canonical correlation analysis (LCCA) is generalized by
applying a structured transform to the joint probability distribution of the

An expression for the photon condensate in quantum electrodynamics is
presented and generalized to deduce a simple relation between the gluon

Schweizer, Sklar and Thorp proved in 1960 that a Menger space $(G,D,T)$ under
a continuous $t$-norm $T$, induce a natural topology $\tau$ wich is metrizable.
We extend this result to any probabilistic metric space $(G,D,\star)$ provided
that the triangle function $\star$ is continuous. We prove in this case, that

Source free domain adaptation (SFDA) aims to transfer a trained source model
to the unlabeled target domain without accessing the source data. However, the

chemical-spectrophot... |
Lepton flavor violating Higgs decays can arise in flavor symmetry models
where the Higgs sector is responsible for both the electroweak and the flavor

tightly constrained flavor changing neutral currents are suppressed by a
remnant $Z_3$ sym... |
We identify the scaling limit of the backbone of the high-dimensional
incipient infinite cluster (IIC), both in the finite-range and the long-range
setting. In the finite-range setting, this scaling limit is Brownian motion, in
the long-range setting, it is a stable motion. The proof relies on a novel lace
expansion ... |
The historical microlensing surveys MACHO, EROS, MOA and OGLE (hereafter

events. We sh... |
We report on a 10 ks simultaneous Chandra/HETG-NuSTAR observation of the
Bursting Pulsar, GRO J1744-28, during its third detected outburst since
discovery and after nearly 18 years of quiescence. The source is detected up to

are seen with... |
When there is a certain amount of field inhomogeneity, the biased
ferrimagnetic crystal will exhibit the higher-order magnetostatic (HMS) mode in

both experimentally and theoretically the cross-Kerr-type interaction between
the Kittel mode a... |
We present a statistical study of optical warps in a sample of 540 galaxies,
about five times larger than previous samples. About 40% of all late-type

least hal... |
Decoherence of a central spin coupled to an interacting spin bath via
inhomogeneous Heisenberg coupling is studied by two different approaches,
namely an exact equations of motion (EOMs) method and a Chebyshev expansion

species. The $b$-$... |
Data imbalance and open-ended distribution are two intrinsic characteristics
of the real visual world. Though encouraging progress has been made in tackling
each challenge separately, few works dedicated to combining them towards
real-world scenarios. While several previous works have focused on classifying

In this paper, we focus on the effect of mass-transfer between compact
binaries like neutron-star-neutron-star (NS-NS) systems and
neutron-star-white-dwarf (NS-WD) systems on gravitational waves (GWs). We adopt

approximation to calculate the GW radiat... |

In soccer (or association football), players quickly go from heroes to
zeroes, or vice-versa. Performance is not a static measure but a somewhat

explores I-VAEP ... |
We consider the problem of accurately recovering a matrix B of size M by M ,
which represents a probability distribution over M2 outcomes, given access to

leverag... |
This paper presents hydrodynamic-like model of business cycles aggregate
fluctuations of economic and financial variables. We model macroeconomics as

Advanced data augmentation strategies have widely been studied to improve the
generalization ability of deep learning models. Regional dropout is one of the

The degree anti-Ramsey number $AR_d(H)$ of a graph $H$ is the smallest
integer $k$ for which there exists a graph $G$ with maximum degree at most $k$

this paper we prove a general upper bound on degree anti-Ramsey numbers,
determine the preci... |
The heightened sensitivity observed in non-Hermitian systems at exceptional

We study and classify the purely parabolic discrete subgroups of
$PSL(3,\Bbb{C})$. This includes all discrete subgroups of the Heisenberg group

We propose a scheme to perform a fundamental two-qubit gate between two
trapped ions using ideas from atom interferometry. As opposed to the scheme
considered by J. I. Cirac and P. Zoller, Phys. Rev. Lett. 74, 4091 (1995), it
does not require laser cooling to the motional ground state.

We propose a new type of bistable device for silicon photonics, using the
self-electro-optic effect within an optical cavity. Since the bistability does

instead engineered by means of an optoelectronic feedback, it appears at low
optical powers.... |
In the intracluster medium (ICM) of galaxy clusters, heat and momentum are
