GSID: AHLz0Mj1uCYJ
E Novak, R Razzouk, TE Johnson - The Internet and Higher Education, 2012 - Elsevier

This paper presents a literature review of empirical research related to the use and effect of online social annotation (SA) tools in higher education settings. SA technology is an …

Effects of game‐based learning on students' mathematics achievement: A meta‐analysis

instructional interventions

Tokac U, Novak E, Thompson CG.
GSID: TAIWY04y3nUJ
U Tokac, E Novak, CG Thompson - Journal of Computer …, 2019 - Wiley Online Library

… However, most of the identified mathematics video game studies only provided partial information about the video games and game-based instructional interventions, thus limiting our ability to systematically examine the effects of several moderator variables. To advance …

Effect of adding nanometre-sized heterogeneities on the structural dynamics and the excess wing of a molecular glass former.

Scientific reports

Gupta S, Fischer JK, Lunkenheimer P, Loidl A, Novak E, Jalarvo N, Ohl M.
PMID: 27725747
Sci Rep. 2016 Oct 11;6:35034. doi: 10.1038/srep35034.

We present the relaxation dynamics of glass-forming glycerol mixed with 1.1 nm sized polyhedral oligomeric silsesquioxane (POSS) molecules using dielectric spectroscopy (DS) and two different neutron scattering (NS) techniques. Both, the reorientational dynamics as measured by DS and the...

Microbiome Composition and Function Drives Wound-Healing Impairment in the Female Genital Tract.

PLoS pathogens

Zevin AS, Xie IY, Birse K, Arnold K, Romas L, Westmacott G, Novak RM, McCorrister S, McKinnon LR, Cohen CR, Mackelprang R, Lingappa J, Lauffenburger DA, Klatt NR, Burgener AD.

PLoS Pathog. 2016 Sep 22;12(9):e1005889. doi: 10.1371/journal.ppat.1005889. eCollection 2016 Sep.

The mechanism(s) by which bacterial communities impact susceptibility to infectious diseases, such as HIV, and maintain female genital tract (FGT) health are poorly understood. Evaluation of FGT bacteria has predominantly been limited to studies of species abundance, but not...

Magnetic filament brushes: tuning the properties of a magnetoresponsive supracolloidal coating.

Faraday discussions

Sánchez PA, Pyanzina ES, Novak EV, Cerdà JJ, Sintes T, Kantorovich SS.
PMID: 26786683
Faraday Discuss. 2016;186:241-63. doi: 10.1039/c5fd00133a.

We present a theoretical study on the design of a supramolecular magnetoresponsive coating. The coating is formed by a relatively dense array of supracolloidal magnetic filaments grafted to a surface in a polymer brush-like arrangement. In order to determine...

The hydrolysis of 4-acyloxy-4-substituted-2,5-cyclohexadienones: limitations of aryloxenium ion chemistry.

Journal of the American Chemical Society

Novak M, Glover SA.
PMID: 15926835
J Am Chem Soc. 2005 Jun 08;127(22):8090-7. doi: 10.1021/ja050899q.

The title compounds serve as potential precursors to aryloxenium ions, often proposed, but primarily uncharacterized intermediates in phenol oxidations. The uncatalyzed and acid-catalyzed decomposition of 4-acetoxy-4-phenyl-2,5-cyclohexadienone, 2a, generates the quinol, 3a. (18)O-Labeling studies performed in (18)O-H(2)O, and monitored by...

Chemistry of 4-alkylaryloxenium ion "precursors": sound and fury signifying something?.

The Journal of organic chemistry

Novak M, Brinster AM, Dickhoff JN, Erb JM, Jones MP, Leopold SH, Vollman AT, Wang YT, Glover SA.
PMID: 18027966
J Org Chem. 2007 Dec 21;72(26):9954-62. doi: 10.1021/jo701853e. Epub 2007 Nov 21.

Quinol esters 2b, 2c, and 3b and sulfonamide 4c were investigated as possible precursors to 4-alkylaryloxenium ions, reactive intermediates that have not been previously detected. These compounds exhibit a variety of interesting reactions, but with one possible exception, they...

Analysis of a micropolarizer array-based simultaneous phase-shifting interferometer.

Applied optics

Novak M, Millerd J, Brock N, North-Morris M, Hayes J, Wyant J.
PMID: 16294959
Appl Opt. 2005 Nov 10;44(32):6861-8. doi: 10.1364/ao.44.006861.

Recent technological innovations have enabled the development of a new class of dynamic (vibration-insensitive) interferometer based on a CCD pixel-level phase-shifting approach. We present theoretical and experimental results for an interferometer based on this pixelated phase-shifting technique. Analyses of...

Effects of source shape on the numerical aperture factor with a geometrical-optics model.

Applied optics

Wan DS, Schmit J, Novak E.
PMID: 15074408
Appl Opt. 2004 Apr 01;43(10):2023-8. doi: 10.1364/ao.43.002023.

We study the effects of an extended light source on the calibration of an interference microscope, also referred to as an optical profiler. Theoretical and experimental numerical aperture (NA) factors for circular and linear light sources along with collimated...

Effects of absorbed hydrogen on the electronic properties of (Zr2Fe)(1-x)H(x) metallic glasses.

Journal of physics. Condensed matter : an Institute of Physics journal

Novak M, Kokanović I.
