Magnetic orders and spin-flop transitions in the cobalt doped multiferroic $\rm Mn_{1-x}Co_{x}WO_4$

open access: yes, 2012
We present a comprehensive single crystal neutron diffraction investigation of the $\rm Mn_{1-x}Co_{x}WO_4$ with $0.02\leq x \leq0.30$. At lower concentration $x \leq 0.05$, the system is quickly driven into the multiferroic phase with spin structure ...

Nanoparticle separation with a miniaturized asymmetrical flow field-flow fractionation cartridge

open access: yesFrontiers in Chemistry, 2015
Asymmetrical Flow Field-Flow Fractionation (AF4) is a separation technique applicable to particles over a wide size range. Despite the many advantages of AF4, its adoption in routine particle analysis is somewhat limited by the large footprint of ...

Detecting Error-Related Negativity for Interaction Design [PDF]

open access: yes, 2012
This paper examines the ability to detect a characteristic brain potential called the Error-Related Negativity (ERN) using off-the-shelf headsets and explores its applicability to HCI.

Enrichment of plasma extracellular vesicles for reliable quantification of their size and concentration for biomarker discovery

open access: yesScientific Reports, 2020
Human plasma is a complex fluid, increasingly used for extracellular vesicle (EV) biomarker studies. Our aim was to find a simple EV-enrichment method for reliable quantification of EVs in plasma to be used as biomarker of disease.

Magnetic and multiferroic phases of single-crystalline Mn$_{0.85}$Co$_{0.15}$WO$_4$

open access: yes, 2010
The magnetic and multiferroic phase diagram of Mn$_{0.85}$Co$_{0.15}$WO$_4$ single crystals is investigated by means of magnetic, heat capacity, dielectric, polarization, and neutron scattering experiments.

Radical scavenging activity of some natural tropolones by density functional theory

open access: yesBulletin of the Chemical Society of Ethiopia, 2017
The ground state neutral geometries of some natural tropolones, i.e. stipitatonic acid (AF1), stipitalide (AF2), stipitaldehydic acid (AF3) and methyl stipitate (AF4) have been optimized by using Density Functional Theory (DFT) at B3LYP/6-31G*, B3LYP/6 ...

Mediation of Af4 protein function in the cerebellum by Siah proteins [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
We have established that the gene AF4 , which had long been recognized as disrupted in childhood leukemia, also plays a role in the CNS. Af4 is mutated in the robotic mouse that is characterized by ataxia and Purkinje cell loss.

MLL-AF4 upregulates 5-lipoxygenase expression in t(4;11) leukemia cells via the ALOX5 core promoter

open access: yesFrontiers in Pharmacology
5-Lipoxygenase (5-LO), encoded by the gene ALOX5, is implicated in several pathologies. As key enzyme in leukotriene biosynthesis, 5-LO plays a central role in inflammatory diseases, but the 5-LO pathway has also been linked to development of certain ...

Pressure effects on magnetic ground states in cobalt doped multiferroic Mn$_{1-x}$Co$_{x}$WO$_4$

open access: yes, 2016
Using ambient pressure x-ray and high pressure neutron diffraction, we studied the pressure effect on structural and magnetic properties of multiferroic Mn$_{1-x}$Co$_x$WO$_4$ single crystals ($x=0, 0.05, 0.135$ and $0.17$), and compared it with the ...
