An initial study of educational game applications supporting the STEM education in K-12 systems

STEM education program evaluation

Kwak M, Yurov KM.
GSID: gSycen1notoJ
KM Yurov, SW Beasley, M Kwak, KS Floyd - Online Journal of Applied …, 2014 - iiakm.org

This study develops a novel model focusing on educational game development based on active learning paradigm. The model is designed as a collaborative endeavor involving college constituencies and K-12 stakeholders in the effort to promote adoption of educational game...

A new environment for aerobic anoxygenic phototrophic bacteria: biological soil crusts.

Environmental microbiology reports

Csotonyi JT, Swiderski J, Stackebrandt E, Yurkov V.
PMID: 23766251
Environ Microbiol Rep. 2010 Oct;2(5):651-6. doi: 10.1111/j.1758-2229.2010.00151.x.

Phototrophic microorganisms are critical to the carbon cycling and productivity of biological soil crusts, which enhance water content, nutrient relations and mechanical stability of arid soils. Only oxygen-producing phototrophs, including cyanobacteria and algae, are known from soil crusts, but...

Start-to-end simulation of single-particle imaging using ultra-short pulses at the European X-ray Free-Electron Laser.

IUCrJ

Fortmann-Grote C, Buzmakov A, Jurek Z, Loh ND, Samoylova L, Santra R, Schneidmiller EA, Tschentscher T, Yakubov S, Yoon CH, Yurkov MV, Ziaja-Motyka B, Mancuso AP.
PMID: 28989713
IUCrJ. 2017 Sep 01;4:560-568. doi: 10.1107/S2052252517009496. eCollection 2017 Sep 01.

Single-particle imaging with X-ray free-electron lasers (XFELs) has the potential to provide structural information at atomic resolution for non-crystalline biomolecules. This potential exists because ultra-short intense pulses can produce interpretable diffraction data notwithstanding radiation damage. This paper explores the...

Theory of ferromagnetism in doped excitonic condensates.

Physical review letters

Bascones E, Burkov AA, MacDonald AH.
PMID: 12190486
Phys Rev Lett. 2002 Aug 19;89(8):086401. doi: 10.1103/PhysRevLett.89.086401. Epub 2002 Aug 02.

Nesting in a semimetal can lead to an excitonic-insulator state with spontaneous coherence between conduction and valence bands and a gap for charged excitations. We present a theory of the ferromagnetic state that occurs when the density of electrons...

Anomalous Hall effect in ferromagnetic semiconductors in the hopping transport regime.

Physical review letters

Burkov AA, Balents L.
PMID: 12906629
Phys Rev Lett. 2003 Aug 01;91(5):057202. doi: 10.1103/PhysRevLett.91.057202. Epub 2003 Jul 30.

We present a theory of the anomalous Hall effect in ferromagnetic (Ga,Mn)As in the regime when conduction is due to phonon-assisted hopping of holes between localized states in the impurity band. We show that the microscopic origin of the...

Vortex-Peierls states in optical lattices.

Physical review letters

Burkov AA, Demler E.
PMID: 16712349
Phys Rev Lett. 2006 May 12;96(18):180406. doi: 10.1103/PhysRevLett.96.180406. Epub 2006 May 10.

We show that vortices, induced in cold atom superfluids in optical lattices, may order in a novel vortex-Peierls ground state. In such a state vortices do not form a simple lattice but arrange themselves in clusters, within which the...

Mechanism of mode coupling in multicore fiber lasers.

Optics letters

Kurkov AS, Babin SA, Lobach IA, Kablukov SI.
PMID: 18157258
Opt Lett. 2008 Jan 01;33(1):61-3. doi: 10.1364/ol.33.000061.

We present what is believed to be the first experimental demonstration of a new mechanism of mode coupling in multicore fibers (MCFs) based on their indirect interaction inside the fiber via intermediate mode, analogous to the Bragg mode, which...

Supersolid order from disorder: hard-core bosons on the triangular lattice.

Physical review letters

Melko RG, Paramekanti A, Burkov AA, Vishwanath A, Sheng DN, Balents L.
PMID: 16197107
Phys Rev Lett. 2005 Sep 16;95(12):127207. doi: 10.1103/PhysRevLett.95.127207. Epub 2005 Sep 16.

We study the interplay of Mott localization, geometric frustration, and superfluidity for hard-core bosons with nearest-neighbor repulsion on the triangular lattice. For this model at half filling, we demonstrate that superfluidity survives for arbitrarily large repulsion, and that diagonal...

Physically Triggered Morphology Changes in a Novel .

PMID: 28769882

Fungi are strongly affected by their physical environment. Microfabrication offers the possibility of creating new culture environments and ecosystems with defined characteristics. Here, we report the isolation of a novel member of the fungal genus
