Computing Topological Indices and Polynomials for Line Graphs
Mathematics, 2018 A topological index is a number related to the atomic index that allows quantitative structure–action/property/toxicity connections. All the more vital topological indices correspond to certain physico-concoction properties like breaking point ...

The Astrophysical Journal, 2012 Tadpole galaxies have a giant star-forming region at the end of an elongated intensity distribution. Here we use SDSS data to determine the ages, masses, and surface densities of the heads and tails in 14 local tadpoles selected from the Kiso and Michigan surveys of UV-bright galaxies, and we compare them to tadpoles previously studied in the Hubble ...

Modelling the connectome of a simple spinal cord
Frontiers in Neuroinformatics, 2011 In this paper we develop a computational model of the anatomy of a spinal cord. We address a long-standing ambition of neuroscience to understand the structure-function problem by modelling the complete spinal cord connectome map in the two-day old ...

Scanning electron microscopy of the oral apparatus and buccopharyngeal cavity of Atelognathus salai larvae (Anura, Neobatrachia) [PDF]
Phyllomedusa: Journal of Herpetology, 2006 The aim of this study is to describe the horny structures of the buccal apparatus and buccopharyngeal cavity of A. salai by means ofscanning electron microscopy (SEM), and to compare them to those of the other known species of Atelognathus and related ...

Bilateral tadpole pupils [PDF]
Neurology, 2016 A 19-year-old man with congenital erythropoietic protoporphyria and without family history or prior migraine attacks had recurrent seizures, which were controlled on propofol. Eye examination performed while awake revealed nonreacting bilateral tadpole pupils (TPs) (figure), without other neurologic deficits.

Control of Gemcitabine Activity With Blue and Red Light
Chemistry – A European Journal, EarlyView.Treating cancer with chemotherapy is generally associated with many side effects, which can be addressed by selectively releasing the desired drugs with visible light. Sixteen new blue light‐activatable cytostatics were introduced, with the gemcitabine derivative exhibiting ideal properties.
