A comparative sequence analysis reveals a common GBD/FH3-FH1-FH2-DAD architecture in formins from Dictyostelium, fungi and metazoa

open access: yesBMC Genomics, 2005
Background Formins are multidomain proteins defined by a conserved FH2 (formin homology 2) domain with actin nucleation activity preceded by a proline-rich FH1 (formin homology 1) domain.

Analysis of Suture Manipulation Forces for Teleoperation with Force Feedback [PDF]

open access: yes, 2002
Despite many successes with teleoperated robotic surgical systems, some surgeons feel that the lack of haptic (force or tactile) feedback is detrimental in applications requiring fine suture manipulation. In this paper, we study the difference between applied suture forces in three knot tying exercises: hand ties, instrument ties (using needle drivers),

An Improved Algorithm for Unmixing First-Order Reversal Curve Diagrams Using Principal Component Analysis [PDF]

open access: yes, 2018
First‐order reversal curve (FORC) diagrams of synthetic binary mixtures with single‐domain, vortex state, and multidomain end‐members (EMs) were analyzed using principal component analysis (FORC‐PCA). Mixing proportions derived from FORC‐PCA are shown to

The Nature of Ferromagnetism in a System of Self-Ordered α-FeSi2 Nanorods on a Si(111)-4° Vicinal Surface: Experiment and Theory

open access: yesNanomaterials, 2022
In this study, the appearance of magnetic moments and ferromagnetism in nanostructures of non-magnetic materials based on silicon and transition metals (such as iron) was considered experimentally and theoretically.

FORC analysis of magnetocaloric Heusler-type alloys

open access: yes, 2016
The thermomagnetic hysteresis loops of a Ni45.7Mn36.6In13.5Co4.2 Heusler-type alloy exhibiting inverse magnetocaloric effect were studied with the help of First Order Reversal Curves (FORC).

Activating Paper Applying Gelatin, Starch and Chitosan Coatings Loaded With O/W Emulsions Encapsulating Rutin, Carvacrol and α‐Tocopherol

open access: yesPackaging Technology and Science, EarlyView.
Emulsion type governed the microstructure and functionality of papers coated with biopolymers matrix loaded with hydrophobic bioactives encapsulated into O/W emulsions. Emulsified systems improved UV–Vis barrier and antioxidant activity, whereas gelatin coatings with conventional or Pickering emulsions provided the greatest mechanical reinforcement ...

Preisach model and Forc analysis applied to exchang biased films

open access: yes, 2008
Neste trabalho foram produzidos filmes finos de Si[100]/buffer/NiFe/FeMn/Ta (buffer = Cu; Ta) e válvulas de spin de Si[100]/Cu/NiFe/Cu/NiFe/FeMn/Ta via Sputtering, e seus comportamentos magnéticos foram estudados analisando curvas de inversão de primeira

In situ crystallization and magnetic measurement of hexaferrite glass-ceramics

open access: yesAIP Advances, 2021
Glass-ceramic (GC) materials have the formability advantages of glasses and the opportunity for controlled crystallization of functional ceramic phases. Here, we obtain GCs containing the hard magnetic phase Sr-hexaferrite (SrFe12O19) from a borate glass.

Amidst (waste) abundance: world‐making and struggles in hosting a municipal landfill in the Bolivian lowlands Au milieu de l'abondance (de déchets) : fabrication du monde et luttes liées à la gestion d'une décharge municipale dans les basses terres de Bolivie

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
In recent decades, solid waste has proliferated worldwide, becoming a pressing global issue. This article explores the role of Indigenous people dwelling within and upon emerging waste scenarios, with a specific focus on involved forms of sociality and ontological contestation. Drawing on the case of a municipal landfill sited on a Guarani community in

Angular dependent FORC and FMR of exchange-biased NiFe multilayer films [PDF]

open access: yes, 2017
Dynamic ferromagnetic resonance (FMR, X-band 9.8 GHz) and static first-order reversal curve (FORC) techniques are combined to study the intrinsic exchange-bias distribution via measurements of in-plane angular variation in (FeNi/IrMn)n multilayers.
