Ions in Hall effect thrusters are often characterized by a low collisionality. In the presence of acceleration fields and azimuthal electric field waves, this results in strong deviations from thermodynamic equilibrium, introducing kinetic effects. This work investigates the application of the 14-moment maximum-entropy... | https://arxiv.org/abs/2202.04159v3 |
The abundance ratio of $^{14}$N$/^{15}$N is, in principle, a powerful tool for tracing stellar nucleosynthesis. This work aims to measure and analyze ($^{14}$N/$^{15}$N)$\times$($^{13}$C/$^{12}$C) and $^{14}$N$/^{15}$N abundance ratios in massive star-forming regions across a range of galactocentric distances to provid... | https://arxiv.org/abs/2503.02520v1 |
Here we present an analysis of 14 transit light curves of the hot Jupiter HAT-P-54 b. Thirteen of our datasets were obtained with the 6-inch MicroObservatory telescope, Cecilia, and one was measured with the 61-inch Kuiper Telescope. We used the EXOplanet Transit Interpretation Code (EXOTIC) to reduce 49 datasets in or... | https://arxiv.org/abs/2406.18487v1 |
The nitrogen-vacancy (NV) centers (NCVSi) - in 4H silicon carbide (SiC) constitute an ensemble of spin S = 1 solid state qubits interacting with the surrounding 14N and 29Si nuclei. As quantum applications based on a polarization transfer from the electron spin to the nuclei require the knowledge of the electron-nuclea... | https://arxiv.org/abs/2404.06933v1 |
In this paper, 14-velocity and 18-velocity multiple-relaxation-time (MRT)
lattice Boltzmann (LB) models are proposed for three-dimensional incompressible
flows. These two models are constructed based on the incompressible LBGK model
proposed by He et al. (Chin. Phys., 2004, 13: 40-46) and the MRT LB model
proposed by d... | http://arxiv.org/abs/1503.03337v1 |
In today's connected society, many people rely on mHealth and self-tracking (ST) technology to help them adopt healthier habits with a focus on breaking their sedentary lifestyle and staying fit. However, there is scarce evidence of such technological interventions' effectiveness, and there are no standardized methods ... | https://arxiv.org/abs/2104.11483v3 |
We present a homogeneously-selected sample of 15779 candidate binary systems with main sequence primary stars and orbital periods shorter than 5 days. The targets were selected from TESS full-frame image lightcurves on the basis of their tidally-induced ellipsoidal modulation. Spectroscopic follow-up suggests a sample ... | https://arxiv.org/abs/2211.06194v2 |
This article is an extended version of the article published by EDP Sciences at the occasion of the 150 years of the ``Soci\'et\'e Fran\c{c}aise de Physique'' (in French) | https://arxiv.org/abs/2311.15042v1 |
Using new annual data of 16 developed countries across bond, equity, and housing markets, I study the return predictability using the payout-price ratios, i.e., coupon price, dividend price, and rent price. None of the 48 country-asset combinations shows consistent in-sample and out-of-sample performance with positive ... | https://arxiv.org/abs/2209.00121v1 |
This book, which is in Spanish, provides detailed descriptions, including over 550 mathematical formulas, for over 150 trading strategies across a host of asset classes (and trading styles). This includes stocks, options, fixed income, futures, ETFs, indexes, commodities, foreign exchange, convertibles, structured asse... | https://arxiv.org/abs/1912.04492v1 |
We have detected four flares from UV Ceti at 154 MHz using the Murchison
Widefield Array. The flares have flux densities between 10--65 mJy --- a factor
of 100 fainter than most flares in the literature at these frequencies --- and
are only detected in polarization. The circular polarized fractions are limited
to $>27$... | http://arxiv.org/abs/1702.03030v1 |
BACKGROUND: 155Tb represents a potentially useful radionuclide for diagnostic medical applications, but its production remains a challenging problem. A recent experimental campaign, conducted with low-energy proton beams impinging on a 155Gd target with 91.9% enrichment, demonstrated a significant co-production of 156g... | https://arxiv.org/abs/2309.06250v1 |
We present 1.58-bit FLUX, the first successful approach to quantizing the state-of-the-art text-to-image generation model, FLUX.1-dev, using 1.58-bit weights (i.e., values in {-1, 0, +1}) while maintaining comparable performance for generating 1024 x 1024 images. Notably, our quantization method operates without access... | https://arxiv.org/abs/2412.18653v1 |
{ The ground-state to ground-state electron-capture $Q$ value of $^{159}$Dy ($3/2^-$) has been measured directly utilizing the double Penning trap mass spectrometer JYFLTRAP. A value of 364.73(19)~keV was obtained from a measurement of the cyclotron frequency ratio of the decay parent $^{159}$Dy and the decay daughter ... | https://arxiv.org/abs/2106.06626v2 |
Quasi-one-dimensional magnets can host an ordered longitudinal spin-density wave state (LSDW) in magnetic field at low temperature, when longitudinal correlations are strengthened by Ising anisotropies. In the S = 1/2 Heisenberg antiferromagnet YbAlO3 this happens via Ising-like interchain interactions. Here, we report... | https://arxiv.org/abs/2412.21144v2 |
