Optical attosecond pulses and tracking the nonlinear response of bound electrons.

Nature

Hassan MT, Luu TT, Moulet A, Raskazovskaya O, Zhokhov P, Garg M, Karpowicz N, Zheltikov AM, Pervak V, Krausz F, Goulielmakis E.
PMID: 26842055
Nature. 2016 Feb 04;530(7588):66-70. doi: 10.1038/nature16528.

The time it takes a bound electron to respond to the electromagnetic force of light sets a fundamental speed limit on the dynamic control of matter and electromagnetic signal processing. Time-integrated measurements of the nonlinear refractive index of matter...

Learning molecular energies using localized graph kernels.

The Journal of chemical physics

Ferré G, Haut T, Barros K.
PMID: 28330348
J Chem Phys. 2017 Mar 21;146(11):114107. doi: 10.1063/1.4978623.

Recent machine learning methods make it possible to model potential energy of atomic configurations with chemical-level accuracy (as calculated from ab initio calculations) and at speeds suitable for molecular dynamics simulation. Best performance is achieved when the known physical...

Taphonomy and palaeoecology of Late Triassic (Carnian) ammonoid concentrations from the Taurus Mountains, Turkey.

Lethaia

Mayrhofer S, Lukeneder A, Krystyn L.
PMID: 28111481
Lethaia. 2017 Jan;50(1):87-104. doi: 10.1111/let.12179. Epub 2016 May 21.

The deposits of the Carnian Kasımlar Formation within the Taurus Platform Units of south-western Turkey represent an important archive of a Late Triassic ecosystem. New palaeontological information was obtained by analysing the

Sheffield spinal pathway audit cycle - pathways, mountains and the view from the top.

British journal of pain

Hart O, Ryton BA.
PMID: 26516533
Br J Pain. 2014 Feb;8(1):43-8. doi: 10.1177/2049463713504387.

There is good evidence to suggest that a proactive stratified approach to management of spinal pain, taking into account psychosocial as well as biological factors, can realise significant savings for health-care systems and perhaps more importantly, health benefits for...

Whole-Brain Atrophy Rate in Idiopathic Parkinson's Disease, Multiple System Atrophy, and Progressive Supranuclear Palsy.

Parkinson's disease

Guevara C, Bulatova K, Barker GJ, Gonzalez G, Crossley N, Kempton MJ.
PMID: 27190673
Parkinsons Dis. 2016;2016:9631041. doi: 10.1155/2016/9631041. Epub 2016 Apr 14.

In multiple system atrophy (MSA) and progressive supranuclear palsy (PSP), the absence of surrogate endpoints makes clinical trials long and expensive. We aim to determine annualized whole-brain atrophy rates (a-WBAR) in idiopathic Parkinson's disease (IPD), MSA, and PSP. Ten...

The utility of serum biomarkers to detect myocardial alterations induced by Imatinib in rats.

Pharmacology research & perspectives

Herman E, Knapton A, Zhang J, Estis J, Todd J, Lipshultz S.
PMID: 25505575
Pharmacol Res Perspect. 2014 Feb;2(1):e00015. doi: 10.1002/prp2.15. Epub 2014 Mar 03.

BACKGROUND: Imatinib (Imb) is a tyrosine kinase inhibitor with cardiotoxic activity (decreases in left ventricular function and congestive heart failure) in patients. Currently, clinical diagnosis of Imb cardiotoxicity relies primarily on evaluation of left ventricular function, Imb also induces...

Toca 511 is a novel retroviral replicating vector, encoding a modified yeast cytosine deaminase, administered to recurrent high grade glioma patients in Phase 1 trials by stereotactic, transcranial injection into the tumor or into the walls of the resection...

Analytical equation of state with three-body forces: application to noble gases.

The Journal of chemical physics

del Río F, Díaz-Herrera E, Guzmán O, Moreno-Razo JA, Ramos JE.
PMID: 24320280
J Chem Phys. 2013 Nov 14;139(18):184503. doi: 10.1063/1.4829055.

We developed an explicit equation of state (EOS) for small non polar molecules by means of an effective two-body potential. The average effect of three-body forces was incorporated as a perturbation, which results in rescaled values for the parameters...

High-pressure stabilization of argon fluorides.

Physical chemistry chemical physics : PCCP

Kurzydłowski D, Zaleski-Ejgierd P.
PMID: 26742478
Phys Chem Chem Phys. 2016 Jan 28;18(4):2309-13. doi: 10.1039/c5cp05725f.

On account of the rapid development of noble gas chemistry in the past half-century both xenon and krypton compounds can now be isolated in macroscopic quantities. The same does not hold true for the next lighter group 18 element,...

A sample cell for in situ electric-field-dependent structural characterization and macroscopic strain measurements.

Journal of synchrotron radiation

Hossain MJ, Wang L, Wang Z, Khansur NH, Hinterstein M, Kimpton JA, Daniels JE.
PMID: 27140148
J Synchrotron Radiat. 2016 May;23:694-9. doi: 10.1107/S1600577516005075. Epub 2016 Apr 20.

When studying electro-mechanical materials, observing the structural changes during the actuation process is necessary for gaining a complete picture of the structure-property relationship as certain mechanisms may be meta-stable during actuation. In situ diffraction methods offer a powerful and...
