Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

open access: yesFEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Pathway to Fractional Integrals, Fractional Differential Equations, and Role of the H-Function

open access: yesAxioms
In this paper, the pathway model for the real scalar variable case is re-explored and its connections to fractional integrals, solutions of fractional differential equations, Tsallis statistics and superstatistics in statistical mechanics, the reaction ...

Analysis of Solar Neutrino Data from Super-Kamiokande I and II

open access: yesEntropy, 2014
We are going back to the roots of the original solar neutrino problem: the analysis of data from solar neutrino experiments. The application of standard deviation analysis (SDA) and diffusion entropy analysis (DEA) to the Super-Kamiokande I and II data ...

Outer Space as a Global Commons: An Empirical Study of Space Arrangements

open access: yesInternational Journal of the Commons, 2023
The designation of outer space as a global commons is a contentious issue. Some argue that officially recognizing it as such could discourage private investment, while others claim that it would not sufficiently promote sustainability.

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

open access: yesFEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

THE SECURITY IMPACT OF THE MILITARIZATION OF OUTER SPACE

open access: yesBulletin of "Carol I" National Defense University, 2022
The competition for the military conquest of outer space dominated the public agenda during the Cold War. It was the spatial side of the geopolitical competition between the capitalist West and the communist East.

Metric properties of Outer Space [PDF]

open access: yesPublicacions Matemàtiques, 2011
We define metrics on Culler-Vogtmann space, which are an analogue of the Teichmuller metric and are constructed using stretching factors. In fact the metrics we study are related, one being a symmetrised version of the other. We investigate the basic properties of these metrics, showing the advantages and pathologies of both choices.

Automorphisms of two-dimensional right-angled Artin groups

open access: yes, 2007
We study the outer automorphism group of a right-angled Artin group A_G in the case where the defining graph G is connected and triangle-free. We give an algebraic description of Out(A_G) in terms of maximal join subgraphs in G and prove that the Tits ...

YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

open access: yesFEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

PING-PONG AND OUTER SPACE [PDF]

open access: yesJournal of Topology and Analysis, 2010
We prove that, if φ, ψ ∈ Out (FN) are hyperbolic iwips (irreducible with irreducible powers) such that 〈φ, ψ〉 ⊆ Out (FN) is not virtually cyclic, then some high powers of φ and ψ generate a free subgroup of rank two for which all nontrivial elements are again hyperbolic iwips.
