M31N 2008-05d: A M 31 disk nova with a dipping supersoft X-ray light curve

open access: yes, 2012
Classical novae (CNe) represent a major class of supersoft X-ray sources (SSSs) in the central region of our neighbouring galaxy M 31. Significantly different SSS properties of CNe in the M 31 bulge and disk were indicated by recent X-ray population ...

International Rotifer Symposia: prospects and retrospects from Rotifera XI [PDF]

open access: yes, 2006
The XI International Rotifer Symposium was held during 11–18 March, 2006 at the National Autonomous University of Mexico Campus Iztacala located at the North Mexico City (Mexico). These triennial international meetings, first organized in Austria by Late

Weakly Supervised Source-Specific Sound Level Estimation in Noisy Soundscapes [PDF]

open access: yesarXiv, 2021
While the estimation of what sound sources are, when they occur, and from where they originate has been well-studied, the estimation of how loud these sound sources are has been often overlooked. Current solutions to this task, which we refer to as source-specific sound level estimation (SSSLE), suffer from challenges due to the impracticality of ...

Semiosis and pragmatism: toward a dynamic concept of meaning [PDF]

open access: yes, 2006
Philosophers and social scientists of diverse orientations have suggested that the pragmatics of semiosis is germane to a dynamic account of meaning as process. Semiosis, the central focus of C. S.

Spin-Statistic Selection Rules for Multi-Equal-Photon Transitions in Atoms: Extension of the Landau-Yang Theorem to Multiphoton Systems [PDF]

open access: yesarXiv, 2014
We establish the existence of spin-statistic selection rules (SSSR) for multi-equal-photon transitions in atomic systems. These selection rules are similar to those for systems of many equivalent electrons in atomic theory. The latter ones are the direct consequence of Pauli exclusion principle.

How binary interactions affect spectral stellar population synthesis [PDF]

open access: yes, 2007
Single-star stellar population (ssSSP) models are usually used for stellar population studies. However, more than 50% of stars are in binaries and evolve differently from single stars. This suggests that the effects of binary interactions should be considered when modeling the stellar populations of galaxies and star clusters.

Every symmetric Kubo-Ando connection has the order-determining property on $\mathcal B(H)$ [PDF]

open access: yesarXiv, 2023
In \cite{molnar} L.~Molnar studied the question of whether the L\"owner partial order on the positive cone of an operator algebra is determined by the norm of any arbitrary Kubo-Ando mean. He affirmatively answered the question for certain classes of Kubo-Ando means and left as an open problem the general case.

An Equilibrium for Frustrated Quantum Spin Systems in the Stochastic State Selection Method

open access: yes, 2007
We develop a new method to calculate eigenvalues in frustrated quantum spin models. It is based on the stochastic state selection (SSS) method, which is an unconventional Monte Carlo technique we have investigated in recent years.

A New Ultracool White Dwarf Discovered in the SuperCOSMOS Sky Survey [PDF]

open access: yes, 2007
We present photographic B, R and I photometry, and optical and near-infrared spectroscopy, of a new ultracool white dwarf (UCWD) discovered in the SuperCOSMOS Sky Survey. The spectrum of SSSJ1556-0806 shows strong flux suppression due to the presence of collisionally induced absorption by molecular hydrogen (H2CIA), a feature characteristic of the cool,

SSS3D: Fast Neural Architecture Search For Efficient Three-Dimensional Semantic Segmentation [PDF]

open access: yesarXiv, 2023
We present SSS3D, a fast multi-objective NAS framework designed to find computationally efficient 3D semantic scene segmentation networks. It uses RandLA-Net, an off-the-shelf point-based network, as a super-network to enable weight sharing and reduce search time by 99.67% for single-stage searches. SSS3D has a complex search space composed of sampling
