Multi-modal molecular diffuse optical tomography system for small animal imaging.

Measurement science & technology

Guggenheim JA, Basevi HR, Frampton J, Styles IB, Dehghani H.
PMID: 24954977
Meas Sci Technol. 2013;24(10):105405. doi: 10.1088/0957-0233/24/10/105405.

A multi-modal optical imaging system for quantitative 3D bioluminescence and functional diffuse imaging is presented, which has no moving parts and uses mirrors to provide multi-view tomographic data for image reconstruction. It is demonstrated that through the use of...

Two-Phase and Graph-Based Clustering Methods for Accurate and Efficient Segmentation of Large Mass Spectrometry Images.

Analytical chemistry

Dexter A, Race AM, Steven RT, Barnes JR, Hulme H, Goodwin RJA, Styles IB, Bunch J.
PMID: 28849641
Anal Chem. 2017 Nov 07;89(21):11293-11300. doi: 10.1021/acs.analchem.7b01758. Epub 2017 Oct 25.

Clustering is widely used in MSI to segment anatomical features and differentiate tissue types, but existing approaches are both CPU and memory-intensive, limiting their application to small, single data sets. We propose a new approach that uses a graph-based...

Perpendicular magnetic anisotropy of two-dimensional Rashba ferromagnets.

Physical review. B

Kim KW, Lee KJ, Lee HW, Stiles MD.
PMID: 28596998
Phys Rev B. 2016 Nov;94(18). doi: 10.1103/PhysRevB.94.184402. Epub 2016 Nov 03.

We compute the magnetocrystalline anisotropy energy within two-dimensional Rashba models. For a ferromagnetic free-electron Rashba model, the magnetic anisotropy is exactly zero regardless of the strength of the Rashba coupling, unless only the lowest band is occupied. For this...

Physical review. B

Grytsyuk S, Belabbes A, Haney PM, Lee HW, Lee KJ, Stiles MD, Schwingenschögl U, Manchon A.
PMID: 27441303
Phys Rev B. 2016 May 01;93(17). doi: 10.1103/PhysRevB.93.174421. Epub 2016 May 23.

We systematically investigate the spin-orbit coupling-induced band splitting originating from inversion symmetry breaking at the interface between a Co monolayer and 4

Chirality from interfacial spin-orbit coupling effects in magnetic bilayers.

Physical review letters

Kim KW, Lee HW, Lee KJ, Stiles MD.
PMID: 24313509
Phys Rev Lett. 2013 Nov 22;111(21):216601. doi: 10.1103/PhysRevLett.111.216601. Epub 2013 Nov 19.

As nanomagnetic devices scale to smaller sizes, spin-orbit coupling due to the broken structural inversion symmetry at interfaces becomes increasingly important. Here, we study interfacial spin-orbit coupling effects in magnetic bilayers using a simple Rashba model. The spin-orbit coupling...

Current-induced spin-wave excitations in a single ferromagnetic layer.

Physical review letters

Ji Y, Chien CL, Stiles MD.
PMID: 12689019
Phys Rev Lett. 2003 Mar 14;90(10):106601. doi: 10.1103/PhysRevLett.90.106601. Epub 2003 Mar 11.

Evidence for a current-induced spin-transfer torque effect has been investigated in a series of point contacts to single ferromagnetic layers. At specific current densities, abrupt resistance changes, similar to those attributed to current-induced spin-wave excitations in multilayers, have been...

Enhanced magnetoresistance induced by spin transfer torque in granular films with a magnetic field.

Physical review letters

Chen TY, Huang SX, Chien CL, Stiles MD.
PMID: 16803201
Phys Rev Lett. 2006 May 26;96(20):207203. doi: 10.1103/PhysRevLett.96.207203. Epub 2006 May 26.

Spin-transfer torques (STT) provide a mechanism to alter the magnetic configurations of magnetic heterostructures, a result previously only achieved by an external magnetic field. In granular solids, we demonstrate a new form of STT effect that can be exploited...

Identification of the dominant precession-damping mechanism in Fe, Co, and Ni by first-principles calculations.

Physical review letters

Gilmore K, Idzerda YU, Stiles MD.
PMID: 17678253
Phys Rev Lett. 2007 Jul 13;99(2):027204. doi: 10.1103/PhysRevLett.99.027204. Epub 2007 Jul 09.

The Landau-Lifshitz equation reliably describes magnetization dynamics using a phenomenological treatment of damping. This Letter presents first-principles calculations of the damping parameters for Fe, Co, and Ni that quantitatively agree with existing ferromagnetic resonance measurements. This agreement establishes the...

The support of social networks is a fundamental aspect for the social inclusion of people with mental health problems. This study seeks to identify and analyze the difficulties and possibilities of users of a Psychosocial Care Center (CAPS) in...
