Expert Perspectives on a Clinical Challenge: Hematologic Malignancies and Vasculitis
Arthritis &Rheumatology, Accepted Article.Systemic vasculitis describes a collection of rare diseases each caused by inflammation of blood vessel walls that can cause severe systemic complications [[3, 4]](#ref‐0003). The pattern of vascular inflammation and resultant damage is frequently variable and may be mimicked, or directly triggered, by infection or malignancy.

The Astrophysical JournalUsing an updated and significantly augmented sample of Cepheid and tip of the red giant branch (TRGB) distances to 28 nearby spiral and irregular galaxies, covering a wide range of metallicities, we have searched for evidence of a correlation of the zero-

Limit theorems for continuous time branching flows [PDF]
arXiv, 2012 We construct a flow of continuous time and discrete state branching processes. Some scaling limit theorems for the flow are proved, which lead to the path-valued branching processes and nonlocal branching superprocesses over the positive half line studied in Li (2012).

Washington Photometry of the Red Giant Branch in NGC 6388
The Astronomical Journal, 2007 We present Washington photometry of the giant branches of the relatively metal-rich globular cluster NGC 6388 and compare it with 47 Tuc. By examining the spatial distribution of stellar colors across the red giant branch and using spectroscopic data on several bright giants, we found that NGC 6388's center is affected by differential reddening of at ...

Rotation in sdB stars as revealed by stellar oscillations
Open Astronomy, 2018 An interesting opportunity offered by the detection of stellar oscillations is the possibility to infer the internal rotation rate of a star through the so-called rotational splittings. Such seismic measurements remained rather scarce for hot B subdwarf (

Cyclic branched covers of alternating knots and $L$-spaces [PDF]
arXiv, 2014 For any alternating knot, it is known that the double branched cover of the $3$-sphere branched over the knot is an $L$-space. We show that the three-fold cyclic branched cover is also an $L$-space for any genus one alternating knot.

The Astrophysical JournalThe precise definition of the lower mass limit of red supergiant stars (RSGs) is an open question in astrophysics and does not attract much attention.

Double branched covers of tunnel number one knots [PDF]
arXiv, 2019 We provide criteria ensuring that a tunnel number one knot $K$ is not determined by its double branched cover, in the sense that the double branched cover is also the double branched cover of a knot $K'$ not equivalent to $K$.

Can Life develop in the expanded habitable zones around Red Giant Stars?
, 2005 We present some new ideas about the possibility of life developing around sub-giant and red giant stars. Our study concerns the temporal evolution of the habitable zone.

The Astrophysical Journal LettersAbstract The tip of the red giant branch (TRGB) is an important standard candle for determining luminosity distances. Although several 105 small-amplitude red giant stars (SARGs) have been discovered, variability was previously considered irrelevant for the TRGB as a standard candle.
