Darboux theory of integrability for real polynomial vector fields on $\sss^n$ [PDF]
This is a survey on the Darboux theory of integrability for polynomial vector fields, first in $\R^n$ and second in the $n$-dimensional sphere $\sss^n$. We also provide new results about the maximum number of parallels and meridians that a polynomial vector field $\X$ on $\sss^n$ can have in function of its degree.

SSSPMJ0829-1309: A new nearby L dwarf detected in SuperCOSMOS Sky Surveys [PDF]
The SuperCOSMOS Sky Surveys provide a complete coverage of the Southern sky in three passbands (photographic B_J, R and I) and at different epochs (Hambly et al. 2001a,b,c). These data are the basis for a new high proper motion survey which aims at finding extremely red nearby dwarf stars and brown dwarfs.

SSSegmenation: An Open Source Supervised Semantic Segmentation Toolbox Based on PyTorch [PDF]
This paper presents SSSegmenation, which is an open source supervised semantic image segmentation toolbox based on PyTorch. The design of this toolbox is motivated by MMSegmentation while it is easier to use because of fewer dependencies and achieves superior segmentation performance under a comparable training and testing setup.

Millisecond solar radio bursts in the metric wavelength range [PDF]
A study and classification of super-short structures (SSSs) recorded during metric type IV bursts is presented. The most important property of SSSs is their duration, at half power ranging from 4-50 ms, what is up to 10 times shorter than spikes at corresponding frequencies. The solar origin of the SSSs is confirmed by one-to-one correspondence between

Transient-grating single-shot supercontinuum spectral interferometry (TG-SSSI) [PDF]
We present a technique for the single-shot measurement of the space- and time-resolved spatiotemporal amplitude and phase of an ultrashort laser pulse. The method, transient-grating single-shot supercontinuum spectral interferometry (TG- SSSI), is demonstrated by the space-time imaging of short pulses carrying spatiotemporal optical vortices (STOVs ...

Neutrino Capture Cross Sections for Ar-40 and beta-decay of Ti-40 [PDF]
Shell-model calculations of solar neutrino absorption cross sections for $^{40}$Ar, the proposed component of the ICARUS detector, are presented. It is found that low-lying Gamow-Teller transitions lead to a significant enhancement of the absorption rate

Observational Evidence for Expansion in the SSS spectra of Novae
For several novae, a bright X-ray source with a spectrum resembling the class of Super Soft X-ray Sources (SSS) has been observed a few weeks to months after outburst.

Early Super Soft Source spectra in RS Oph [PDF]
Recent Swift X-ray monitoring campaigns of novae have revealed extreme levels of variability during the early super-soft-source (SSS) phase. The first time this was observed was during the 2006 outburst of the recurrent nova RS Oph which was also ...

SSPMJ1102-3431 brown dwarf characterization from accurate proper motion and trigonometric parallax [PDF]
In 2005, Scholz and collaborators (Scholz et al. 2005) discovered, in a proper motion survey, a young brown dwarf SSSPMJ1102-3431(SSSPMJ1102) of spectral type M8.5, probable member of the TW Hydrae Association (TWA) and possible companion of the T Tauri star TW Hya. The physical characterization of SSSPMJ1102 was based on the hypothesis that it forms a
