Induced gravitational collapse at extreme cosmological distances: the case of GRB 090423 [PDF]

open access: yes, 2014
CONTEXT: The induced gravitational collapse (IGC) scenario has been introduced in order to explain the most energetic gamma ray bursts (GRBs), Eiso=10^{52}-10^{54}erg, associated with type Ib/c supernovae (SNe). It has led to the concept of binary-driven

Targeting Aurora Kinases as Essential Cell‐Cycle Regulators to Deliver Multi‐Stage Antimalarials Against Plasmodium Falciparum

open access: yesAngewandte Chemie, Volume 137, Issue 51, December 15, 2025.
In this study, we repurposed human Aurora kinase‐specific inhibitors to identify potential antimalarial agents. Two inhibitors, hesperadin and TAE684, exhibited sub‐micromolar activity across multiple parasite stages, with hesperadin demonstrating significant potency and selectivity by specifically targeting PfArk1.

The Effect Of Microscopic Correlations On The Information Geometric Complexity Of Gaussian Statistical Models

open access: yes, 2010
We present an analytical computation of the asymptotic temporal behavior of the information geometric complexity (IGC) of finite-dimensional Gaussian statistical manifolds in the presence of microcorrelations (correlations between microvariables).

Effect of particle size on the surface properties and morphology of ground flax [PDF]

open access: yes, 2013
Flax fibers were ground with a ball-mill and four fractions with different size ranges were collected by sieving. These were tested for water sorption, degree of polymerization (DP), copper number, hydroxyl number and analyzed by X-ray diffraction (XRD),
