New-Onset Refractory Status Epilepticus with Claustrum Damage: Definition of the Clinical and Neuroimaging Features.

Frontiers in neurology

Meletti S, Giovannini G, d'Orsi G, Toran L, Monti G, Guha R, Kiryttopoulos A, Pascarella MG, Martino T, Alexopoulos H, Spilioti M, Slonkova J.

Front Neurol. 2017 Mar 27;8:111. doi: 10.3389/fneur.2017.00111. eCollection 2017.

New-onset refractory status epilepticus (NORSE) is a rare but challenging condition occurring in a previously healthy patient, often with no identifiable cause. We describe the electro-clinical features and outcomes in a group of patients with NORSE who all demonstrated...

Ultrason Sonochem. 2018 Jan;40:41-56. doi: 10.1016/j.ultsonch.2017.06.026. Epub 2017 Jun 28.

Cotton-titania nanocomposites with multifunctional properties were synthesized through ultrasonic acoustic method (UAM). Ultrasonic irradiations were used as a potential tool to develop cotton-titania (CT) nanocomposites at low temperature in the presence of titanium tetrachloride and isopropanol. The synthesized samples...

PMID: 28328028
Angew Chem Int Ed Engl. 2017 Apr 18;56(17):4797-4801. doi: 10.1002/anie.201700707. Epub 2017 Mar 22.

A combination of large-scale and micro-scale elemental imaging, yielding elemental distribution maps obtained by, respectively non-invasive macroscopic X-ray fluorescence (MA-XRF) and by secondary electron microscopy/energy dispersive X-ray analysis (SEM-EDX) and synchrotron radiation-based micro-XRF (SR μ-XRF) imaging was employed to...

Neuroprotective Potential of Cell-Based Therapies in ALS: From Bench to Bedside.

Frontiers in neuroscience

Forostyak S, Sykova E.
PMID: 29114200
Front Neurosci. 2017 Oct 24;11:591. doi: 10.3389/fnins.2017.00591. eCollection 2017.

Motor neurons (MN) degeneration is a main feature of amyotrophic lateral sclerosis (ALS), a neurological disorder with a progressive course. The diagnosis of ALS is essentially a clinical one. Most common symptoms include a gradual neurological deterioration that reflect...

Tuning the effective spin-orbit coupling in molecular semiconductors.

Nature communications

Schott S, McNellis ER, Nielsen CB, Chen HY, Watanabe S, Tanaka H, McCulloch I, Takimiya K, Sinova J, Sirringhaus H.
PMID: 28492241
Nat Commun. 2017 May 11;8:15200. doi: 10.1038/ncomms15200.

The control of spins and spin to charge conversion in organics requires understanding the molecular spin-orbit coupling (SOC), and a means to tune its strength. However, quantifying SOC strengths indirectly through spin relaxation effects has proven difficult due to...

Chromatographic and spectroscopic identification and recognition of ammoniacal cochineal dyes and pigments.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy

Chieli A, Sanyova J, Doherty B, Brunetti BG, Miliani C.
PMID: 26985877
Spectrochim Acta A Mol Biomol Spectrosc. 2016 Jun 05;162:86-92. doi: 10.1016/j.saa.2016.03.007. Epub 2016 Mar 09.

In this work a combined chromatographic and spectroscopic approach is used to provide a diagnostic assessment of semi-synthetic ammoniacal cochineal through the syntheses of its dyes and lakes according to art historical recipes. Commercially introduced in the late XIX...

Electric Control of Dirac Quasiparticles by Spin-Orbit Torque in an Antiferromagnet.

Physical review letters

Šmejkal L, Železný J, Sinova J, Jungwirth T.
PMID: 28339249
Phys Rev Lett. 2017 Mar 10;118(10):106402. doi: 10.1103/PhysRevLett.118.106402. Epub 2017 Mar 06.

Spin orbitronics and Dirac quasiparticles are two fields of condensed matter physics initiated independently about a decade ago. Here we predict that Dirac quasiparticles can be controlled by the spin-orbit torque reorientation of the Néel vector in an antiferromagnet....

High Antiferromagnetic Domain Wall Velocity Induced by Néel Spin-Orbit Torques.

Physical review letters

Gomonay O, Jungwirth T, Sinova J.
PMID: 27419586
Phys Rev Lett. 2016 Jul 01;117(1):017202. doi: 10.1103/PhysRevLett.117.017202. Epub 2016 Jun 29.

We demonstrate the possibility to drive an antiferromagnetic domain wall at high velocities by fieldlike Néel spin-orbit torques. Such torques arise from current-induced local fields that alternate their orientation on each sublattice of the antiferromagnet and whose orientation depends...

The localization behavior of noninteracting two-dimensional electrons in a random potential and strong magnetic field is of fundamental interest for the physics of the quantum Hall effect. In order to understand the emergence of power-law delocalization near the discrete...

Measuring the condensate fraction of rapidly rotating trapped boson systems: off-diagonal order from the density profile.

Phys Rev Lett. 2003 Mar 28;90(12):120401. doi: 10.1103/PhysRevLett.90.120401. Epub 2003 Mar 24.

We demonstrate a direct connection between the density profile of a system of ultracold trapped bosonic particles in the rapid-rotation limit and its condensate fraction. This connection can be used to probe the crossover from condensed vortex-lattice states to...

Quantum melting and absence of Bose-Einstein condensation in two-dimensional vortex matter.

Physical review letters

We demonstrate that quantum fluctuations suppress Bose-Einstein condensation of quasi-two-dimensional bosons in a rapidly rotating trap. Our conclusions rest in part on the derivation of an exact expression for the boson action in terms of vortex position coordinates, and...
