Skeletal ontogeny of the caudal complex in Caspian kutum, Rutilus kutum (Kamensky, 1901) (Teleostei: Cyprinidae) during early development [PDF]

Caspian Journal of Environmental Sciences, 2019
Study of skeletal ontogeny during early development is crucial in a successful larviculture. In this study, ontogeny of the caudal complex skeleton in Caspian kutum, Rutilus kutum, was studied from hatching up to 50-day post hatching (dph).

The Dust-to-Gas Ratio in the Small Magellanic Cloud Tail [PDF]

, 2008
The Tail region of the Small Magellanic Cloud (SMC) was imaged using the MIPS instrument on the Spitzer Space Telescope as part of the SAGE-SMC Spitzer Legacy. Diffuse infrared emission from dust was detected in all the MIPS bands.

The long tail of oncogenic drivers in prostate cancer

Nature Genetics, 2018
Comprehensive genomic characterization of prostate cancer has identified recurrent alterations in genes involved in androgen signaling, DNA repair, and PI3K signaling, among others.

The narrow X-ray tail and double H-alpha tails of ESO 137-002 in Abell 3627 [PDF]

, 2013
We present the analysis of a deep Chandra observation of a ~2L_* late-type galaxy, ESO 137-002, in the closest rich cluster A3627. The Chandra data reveal a long (>40 kpc) and narrow tail with a nearly constant width (~3 kpc) to the southeast of the ...

Measuring non-exchangeable tail dependence using tail copulas [PDF]

arXiv, 2021
Quantifying tail dependence is an important issue in insurance and risk management. The prevalent tail dependence coefficient (TDC), however, is known to underestimate the degree of tail dependence and it does not capture non-exchangeable tail dependence since it evaluates the limiting tail probability only along the main diagonal.

Smooth tail index estimation [PDF]

, 2007
Both parametric distribution functions appearing in extreme value theory - the generalized extreme value distribution and the generalized Pareto distribution - have log-concave densities if the extreme value index gamma is in [-1,0].

The tail dependograph [PDF]

Extremes, 2019
All characterizations of non-degenerate multivariate tail dependence structures are both functional and infinite-dimensional. Taking advantage of the Hoeffding--Sobol decomposition, we derive new indices to measure and summarize the strength of dependence in a multivariate extreme value analysis.

The Tails of Protein Kinase A [PDF]

Molecular Pharmacology, 2022
Protein kinase A (PKA) is a holoenzyme consisting of a regulatory (R)-subunit dimer and two catalytic (C)-subunits. There are two major families of C-subunits, Cα and Cβ, and four functionally nonredundant R-subunits (RIα, RIβ, RIIα, RIIβ). In addition to binding to and being regulated by the R-subunits, the C-subunits are regulated by two tail regions

More Than Just a Bandage: Closing the Gap Between Injury and Appendage Regeneration

Frontiers in Physiology, 2019
The remarkable regenerative capabilities of amphibians have captured the attention of biologists for centuries. The frogs Xenopus laevis and Xenopus tropicalis undergo temporally restricted regenerative healing of appendage amputations and spinal cord ...

Fat-Tailed Variational Inference with Anisotropic Tail Adaptive Flows [PDF]

arXiv, 2022
While fat-tailed densities commonly arise as posterior and marginal distributions in robust models and scale mixtures, they present challenges when Gaussian-based variational inference fails to capture tail decay accurately. We first improve previous theory on tails of Lipschitz flows by quantifying how the tails affect the rate of tail decay and by ...
