Existing settings of decentralized learning either require players to have
full information or the system to have certain special structure that may be
hard to check and hinder their applicability to practical systems. To overcome
this, we identify a structure that is simple to check for linear dynamical
system, where ... | http://arxiv.org/abs/2305.09002v1 |
The range and speed of direct ink writing, the workhorse of 3d and 4d
printing, is limited by the practice of liquid extrusion from a nozzle just
above the surface to prevent instabilities to cause deviations from the
required print path. But what if could harness the ``fluid rope trick", whence
a thin stream of viscou... | http://arxiv.org/abs/2302.05853v1 |
Exercise-based rehabilitation programs have been shown to enhance quality of
life and reduce mortality and rehospitalizations. AI-driven virtual
rehabilitation programs enable patients to complete exercises independently at
home while AI algorithms can analyze exercise data to provide feedback to
patients and report th... | http://arxiv.org/abs/2306.09546v1 |
Let $p$ be an odd prime, $F$ a field with a primitive $p^2$th root of unity,
and $E=F(\sqrt[p]{b_1},\sqrt[p]{b_2})$ an elementary abelian extension of
degree $p^2$. This paper studies the cohomological kernel $H^n(E/F,{\mathbb
Z}/p{\mathbb Z}):={\rm ker}(H^n(F,{\mathbb Z}/p{\mathbb Z})\rightarrow
H^n(E,{\mathbb Z}/p{\m... | http://arxiv.org/abs/2305.08308v1 |
The stochastic actor oriented model (SAOM) is a method for modelling social
interactions and social behaviour over time. It can be used to model drivers of
dynamic interactions using both exogenous covariates and endogenous network
configurations, but also the co-evolution of behaviour and social interactions.
In its s... | http://arxiv.org/abs/2304.07312v3 |
We study an optical Raman square lattice with $\mathrm{U}(1)$ synthetic gauge
flux to show chiral spin liquid (CSL) phase for cold atoms based on slave-rotor
theory and spinon mean-field theory, respectively. An effective U($1$) gauge
flux generated by Raman potentials plays a major role in realizing the CSL
phase. By ... | http://arxiv.org/abs/2306.16466v2 |
Ground-based high-resolution spectroscopy (HRS) has detected numerous
chemical species and atmospheric dynamics in exoplanets, most notably ultra-hot
Jupiters (UHJs). However, quantitative estimates on abundances have been
challenging but are essential for accurate comparative characterisation and to
determine formatio... | http://arxiv.org/abs/2305.17228v1 |
Significant progress has been made in speaker dependent Lip-to-Speech
synthesis, which aims to generate speech from silent videos of talking faces.
Current state-of-the-art approaches primarily employ non-autoregressive
sequence-to-sequence architectures to directly predict mel-spectrograms or
audio waveforms from lip ... | http://arxiv.org/abs/2307.01233v1 |
In this note, we briefly present a generalized tensor CUR (GTCUR)
approximation for tensor pairs (X,Y) and tensor triplets (X,Y,Z) based on the
tubal product (t-product). We use the tensor Discrete Empirical Interpolation
Method (TDEIM) to do these extensions. We show how the TDEIM can be utilized to
generalize the cla... | http://arxiv.org/abs/2305.00754v2 |
SPQR-trees are a central component of graph drawing and are also important in
many further areas of computer science. From their inception onwards, they have
always had a strong relation to dynamic algorithms maintaining information,
e.g., on planarity and triconnectivity, under edge insertion and, later on,
also delet... | http://arxiv.org/abs/2301.03972v1 |
We report a two-stage crash process in edge localized mode (ELM) driven by
resistive drift-ballooning modes (RDBMs) numerically simulated in a full
annular torus domain. In the early nonlinear phase, the first crash is
triggered by linearly unstable RDBMs and m/n = 2/1 magnetic islands are
nonlinearly excited via nonli... | http://arxiv.org/abs/2310.04784v1 |
Open quantum systems are inherently coupled to their environments, which in
turn also obey quantum dynamical rules. By restricting to dissipative dynamics,
here we propose a measure that quantifies how far the environment action on a
system departs from the influence of classical noise fluctuations. It relies on
the la... | http://arxiv.org/abs/2305.16136v1 |
