Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Spin-orbit torque engineering via oxygen manipulation
, 2015 Spin transfer torques allow the electrical manipulation of the magnetization at room temperature, which is desirable in spintronic devices such as spin transfer torque memories. When combined with spin-orbit coupling, they give rise to spin-orbit torques

Mature teratoma presenting as orbital cellulitis in a 5-month-old baby
Annals of Saudi Medicine, 2013 We have presented an interesting case of an unexpected orbital tumor in a 5-month-old female healthy baby who presented initially with a 1-week history of acute left proptosis, swollen eyelid, conjunctival chemosis and exposure keratopathy.

Novel Pointing and Stabilizing Manipulator for Optical Space Payloads
Applied Sciences, 2023 Considering that the Line-Of-Sight (LOS) of a small optical payload is mainly connected with the angular motions while insensitive to linear motion, a novel pointing and stabilizing manipulator was proposed for small payloads on a large spacecraft.

Spin-orbit torque emerging from orbital textures in centrosymmetric materials [PDF]
arXiv, 2023 We unveil a hitherto concealed spin-orbit torque mechanism driven by orbital degrees of freedom in centrosymmetric two-dimensional transition metal dichalcogenides (focusing on PtSe${}_2$ ). Using first-principles simulations, tight-binding models and large-scale quantum transport calculations, we show that such a mechanism fundamentally stems from a ...

Orbital magnetism in the half-metallic Heusler alloys [PDF]
Physical Review B 71, 012413 (2005), 2004 Using the fully-relativistic screened Korringa-Kohn-Rostoker method I study the orbital magnetism in the half-metallic Heusler alloys. Orbital moments are almost completely quenched and they are negligible with respect to the spin moments. The change in the atomic-resolved orbital moments can be easily explained in terms of the spin-orbit strength and ...

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms
FEBS Letters, EarlyView.Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...

FEBS Letters, EarlyView.Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Orbit Spaces of Gradient Vector Fields
, 2011 We study orbit spaces of generalized gradient vector fields for Morse functions. Typically, these orbit spaces are non-Hausdorff. Nevertheless, they are quite structured topologically and are amenable to study. We show that these orbit spaces are locally

Asymptotic cone of semisimple orbits for symmetric pairs [PDF]
, 2010 Let G be a reductive algebraic group over the complex field and O_h be a closed adjoint orbit through a semisimple element h. By a result of Borho and Kraft (1979), it is known that the asymptotic cone of the orbit O_h is the closure of a Richardson ...
