Y-Stenting for Bifurcation Aneurysm Coil Embolization: What is the Risk?.

Stroke research and treatment

Spiotta AM, Lena J, Chaudry MI, Turner RD, Turk AS.
PMID: 25120940
Stroke Res Treat. 2014;2014:762389. doi: 10.1155/2014/762389. Epub 2014 Jul 10.

The use of two stents in a "Y" configuration (Y-stenting) to assist with coil embolization of complex bifurcation aneurysms has been accepted as an alternative to clip reconstruction of a select subset of challenging aneurysms. We review the risks...

Structure of carbon dioxide phase IV: breakdown of the intermediate bonding state scenario.

Physical review letters

Datchi F, Giordano VM, Munsch P, Saitta AM.
PMID: 19905813
Phys Rev Lett. 2009 Oct 30;103(18):185701. doi: 10.1103/PhysRevLett.103.185701. Epub 2009 Oct 29.

The existence of "intermediate bonding states" in solid CO2, separating the low-pressure molecular phases from the high-pressure polymeric forms, has been the matter of a long-standing debate. Here we determine the structure of CO2-IV using x-ray diffraction of single...

Proton disorder and superionicity in hot dense ammonia ice.

Physical review letters

Ninet S, Datchi F, Saitta AM.

Phys Rev Lett. 2012 Apr 20;108(16):165702. doi: 10.1103/PhysRevLett.108.165702. Epub 2012 Apr 19.

We report the experimental discovery of a new phase of ammonia ice, stable at pressures above 57 GPa and temperatures above 700 K. The combination of our experimental results and ab initio molecular dynamics simulations reveal that this new...

Synthesis of (d)-erythrose from glycolaldehyde aqueous solutions under electric field.

Chemical communications (Cambridge, England)

Chem Commun (Camb). 2018 Mar 27;54(26):3211-3214. doi: 10.1039/c8cc00045j.

The formation of the first C-C bonds from formaldehyde represents the rate-limiting step of the formose reaction. However, the free-energy surface associated with such a process has never been determined in condensed phase. By means of ab initio molecular...

Fully Quantum Description of the Zundel Ion: Combining Variational Quantum Monte Carlo with Path Integral Langevin Dynamics.

Journal of chemical theory and computation

Mouhat F, Sorella S, Vuilleumier R, Saitta AM, Casula M.
PMID: 28441484
J Chem Theory Comput. 2017 Jun 13;13(6):2400-2417. doi: 10.1021/acs.jctc.7b00017. Epub 2017 May 09.

We introduce a novel approach for a fully quantum description of coupled electron-ion systems from first principles. It combines the variational quantum Monte Carlo solution of the electronic part with the path integral formalism for the quantum nuclear dynamics....
