The instantaneous radial growth rate of stellar discs [PDF]

open access: yes, 2015
We present a new and simple method to measure the instantaneous mass and radial growth rates of the stellar discs of spiral galaxies, based on their star formation rate surface density (SFRD) profiles. Under the hypothesis that discs are exponential with

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

open access: yesFEBS Open Bio, EarlyView.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

Dust Evolution in Protoplanetary Disks

open access: yes, 2014
(abridged) In the core accretion scenario for the formation of planetary rocky cores, the first step toward planet formation is the growth of dust grains into larger and larger aggregates and eventually planetesimals.

The effect of canopy position on growth and mortality in mixed sapling communities during self-thinning [PDF]

open access: yes, 2009
This research investigates how species in the sapling phase differ in growth and survival depending on light availability (as estimated by canopy position) by means of tree-ring analysis and modelling mortality.

Developmental, Neuroanatomical and Cellular Expression of Genes Causing Dystonia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Dystonia is one of the most common movement disorders, with variants in multiple genes identified as causative. However, an understanding of which developmental stages, brain regions, and cell types are most relevant is crucial for developing relevant disease models and therapeutics.

Impact of mistletoe attack (Viscum album ssp. abietis) on the radial growth of silver fir. A case study in the North of Eastern Carpathians [PDF]

open access: yesAnnals of Forest Research, 2009
Viscum album ssp. abietis (Wiesb.) Abrom L. is one of the three subspecies of Viscum album L that is frequently encountered in Romanian forests. The mistletoe has notoriously negative effects on trees and forests health. The mistletoe infections not only

Benefits of Mixtures on Growth Performance of Silver Fir (Abies alba) and European Beech (Fagus sylvatica) Increase With Tree Size Without Reducing Drought Tolerance

open access: yesFrontiers in Forests and Global Change, 2019
To mitigate negative impacts of drought stress in the face of climate change, mixtures of tree species such as those between European beech (Fagus sylvatica) and silver fir (Abies alba) are assumed to lower risks in forest management.

Precise Radial Velocities of Polaris: Detection of Amplitude Growth

open access: yes, 2008
We present a first results from a long-term program of a radial velocity study of Cepheid Polaris (F7 Ib) aimed to find amplitude and period of pulsations and nature of secondary periodicities.

The radial growth of univalent functions

open access: yesJournal of Computational and Applied Mathematics, 2004
Let \(f(z)= z+ a_2z^2+\cdots\) be a function analytic and univalent in the unit disk, i.e. \(f\) belongs to the well-known class \(S\). Denote by \[ \underline\alpha(\theta)= \liminf_{r\to 1-}\,{\log| f(re^{i\theta}|\over \log(1/(1- r))} \] and \(I(f)= \{\theta\in [0, 2\pi): \underline\alpha(\theta)> 0\}\). It follows from a classical result of \textit{

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...
