Sci Rep. 2015 Sep 08;5:13616. doi: 10.1038/srep13616.

Folding is ubiquitous in nature with examples ranging from the formation of cellular components to winged insects. It finds technological applications including packaging of solar cells and space structures, deployable biomedical devices, and self-assembling robots and airbags. Here we...

The Role of Crk Adaptor Proteins in T-Cell Adhesion and Migration.

Frontiers in immunology

Braiman A, Isakov N.
PMID: 26500649
Front Immunol. 2015 Oct 05;6:509. doi: 10.3389/fimmu.2015.00509. eCollection 2015.

Crk adaptor proteins are key players in signal transduction from a variety of cell surface receptors. They are involved in early steps of lymphocyte activation through their SH2-mediated transient interaction with signal transducing effector molecules, such as Cbl, ZAP-70,...

Multi-shape active composites by 3D printing of digital shape memory polymers.

Scientific reports

Wu J, Yuan C, Ding Z, Isakov M, Mao Y, Wang T, Dunn ML, Qi HJ.
PMID: 27071543
Sci Rep. 2016 Apr 13;6:24224. doi: 10.1038/srep24224.

Recent research using 3D printing to create active structures has added an exciting new dimension to 3D printing technology. After being printed, these active, often composite, materials can change their shape over time; this has been termed as 4D...

OBJECTIVE: A study was conducted to investigate the effects of fatigue on the ability of human musculoskeletal system to deal with the onslaught of the heel strike initiated shock waves. DESIGN: Running on a treadmill at the anaerobic threshold...

Exercise Radionuclide Cineangiography for Predicting Long Term Prognosis in Elderly Post Coronary Artery Bypass Graft Patients.

The American journal of geriatric cardiology

Shapira I, Isakov A, Heller I, Topilsky M, Villa Y, Pines A.
PMID: 11416556
Am J Geriatr Cardiol. 2000 May;9(3):162-166. doi: 10.1111/j.1076-7460.2000.80027.x.

ISSUE: The immediate benefits of coronary artery bypass grafting may only be transient. Recent studies which showed that exercise radionuclide cineangiography studies may predict cardiac events and survival had evaluated post coronary artery bypass grafting patients of all ages....

Hard-core bosons on the kagome lattice: valence-bond solids and their quantum melting.

Physical review letters

Isakov SV, Wessel S, Melko RG, Sengupta K, Kim YB.
PMID: 17155288
Phys Rev Lett. 2006 Oct 06;97(14):147202. doi: 10.1103/PhysRevLett.97.147202. Epub 2006 Oct 06.

Using large scale quantum Monte Carlo simulations and dual vortex theory, we analyze the ground state phase diagram of hard-core bosons on the kagome lattice with nearest-neighbor repulsion. In contrast with the case of a triangular lattice, no supersolid...

Unusual liquid state of hard-core bosons on the pyrochlore lattice.

Physical review letters

Banerjee A, Isakov SV, Damle K, Kim YB.
PMID: 18352330
Phys Rev Lett. 2008 Feb 01;100(4):047208. doi: 10.1103/PhysRevLett.100.047208. Epub 2008 Jan 31.

We study the physics of hard-core bosons with unfrustrated hopping (t) and nearest-neighbor repulsion (V) on the three dimensional pyrochlore lattice. At half-filling, we demonstrate that the small V/t superfluid state eventually becomes unstable at large enough V/t to...

Interaction between SiO2 and a KF-KCl-K2SiF6 Melt.

The journal of physical chemistry. B

Zaykov YP, Isakov AV, Zakiryanova ID, Reznitskikh OG, Chemezov OV, Redkin AA.
PMID: 24428731
J Phys Chem B. 2014 Feb 13;118(6):1584-8. doi: 10.1021/jp4086816. Epub 2014 Jan 31.

The solubility mechanism of silica in a fluoride-chloride melt has been determined in situ using Raman spectroscopy. The spectroscopy data revealed that the silica solubility process involved Si-O bond breakage and Si-F bond formation. The process results in the...
