Brill-Noether loci are those subsets of the moduli space M_g determined by
the existence of a linear series of degree d and dimension r. We provide a new
proof of the non-emptiness of the loci when the expected codimension of the
Brill-Noether loci satisfies 0< -rho(g,r,d) \le g-2, r+1\not=g-d+r. 0<
-\rho(g,r,d) \le g-... | http://arxiv.org/abs/2308.10581v2 |
Quantum synchronization has emerged as a crucial phenomenon in quantum
nonlinear dynamics with potential applications in quantum information
processing. Multiple measures for quantifying quantum synchronization exist.
However, there is currently no widely agreed metric that is universally
adopted. In this paper, we pro... | http://arxiv.org/abs/2306.06897v1 |
We are interested in the feedback stabilization of general linear
multi-dimensional first order hyperbolic systems in $\R^d$. Using a Lyapunov
function with a suited weight function dpending on the system under
consideration we show stabilization in $L^2$ for the studied system using a
suitable feedback control. Theref... | http://arxiv.org/abs/2303.05598v2 |
Maximal Extractable Value (MEV) has become a critical issue for blockchain
ecosystems, as it enables validators or block proposers to extract value by
ordering, including or censoring users' transactions. This paper aims to
present a formal approach for determining the appropriate compensation for
users whose transacti... | http://arxiv.org/abs/2306.17024v1 |
The observation of CP violation in meson decays is a testament to the
Cabibbo-Kobayashi-Maskawa (CKM) quark mixing paradigm, and an integral part of
the Standard Model (SM). The SM also predicts the existence of CP violation in
baryon decays that is yet to be observed. A critical test of the SM requires
that CP violati... | http://arxiv.org/abs/2303.02591v1 |
In the present paper, we study several aspects of gravitational lensing
caused by a topologically charged Monopole/Wormhole, both in the weak field
limit and in the strong field limit. We calculate the light deflection and then
use it to determine the observables, with which one can investigate the
existence of these o... | http://arxiv.org/abs/2305.11105v2 |
Modern smartwatches often include photoplethysmographic (PPG) sensors to
measure heartbeats or blood pressure through complex algorithms that fuse PPG
data with other signals. In this work, we propose a collaborative inference
approach that uses both a smartwatch and a connected smartphone to maximize the
performance o... | http://arxiv.org/abs/2306.06129v1 |
On December 2021, a new camera box for two-colour simultaneous visible
photometry was successfully installed on the ASTEP telescope at the Concordia
station in Antarctica. The new focal box offers increased capabilities for the
ASTEP+ project. The opto-mechanical design of the camera was described in a
previous paper. ... | http://arxiv.org/abs/2305.08454v1 |
Compared with the energy efficiency of conventional mobile communication
systems, the energy efficiency of fifth generation (5G) communication systems
has been improved more than 30 times. However, the energy consumption of 5G
communication systems is 3 times of the energy consumption of fourth generation
(4G) communic... | http://arxiv.org/abs/2304.06988v1 |
Virtual Reality (VR), Augmented Reality (AR), Mixed Reality (MR), digital
twin, Metaverse and other related digital technologies have attracted much
attention in recent years. These new emerging technologies are changing the
world significantly. This research introduces a fusion model, i.e. Fusion
Universe (FU), where ... | http://arxiv.org/abs/2305.09992v1 |
Single-cell transcriptomics techniques, such as scRNA-seq, attempt to
characterize gene expression profiles in each cell of a heterogeneous sample
individually. Due to growing amounts of data generated and the increasing
complexity of the computational protocols needed to process the resulting
datasets, the demand for ... | http://arxiv.org/abs/2305.00008v1 |
Large Language Models (LLMs) have shown great potential in solving complex
problems in various fields, including oil and gas engineering and other
