Universities are increasingly using learning communities (LCs) to promote the academic and social integration of entering students, especially within STEM majors. Examining the causal effect of LCs on student networks is necessary to understand the nature and scope of...

Undergraduate research experience in cybersecurity for underrepresented students and students with limited research opportunities

Broadening Participation in Computing AND Program Evaluation

Spin liquid phases for spin-1 systems on the triangular lattice.

Physical review letters

Xu C, Wang F, Qi Y, Balents L, Fisher MP.
PMID: 22463565
Phys Rev Lett. 2012 Feb 24;108(8):087204. doi: 10.1103/PhysRevLett.108.087204. Epub 2012 Feb 23.

Motivated by recent experiments on material Ba3NiSb2O9, we propose two novel spin liquid phases (A and B) for spin-1 systems on a triangular lattice. At the mean field level, both spin liquid phases have gapless fermionic spinon excitations with...

Comparison of different methods for detecting epidermal growth factor receptor mutations in peripheral blood and tumor tissue of non-small cell lung cancer as a predictor of response to gefitinib.

Xu F, Wu J, Xue C, Zhao Y, Jiang W, Lin L, Wu X, Lu Y, Bai H, Xu J, Zhu G, Zhang L.
PMID: 23251095
Onco Targets Ther. 2012;5:439-47. doi: 10.2147/OTT.S37289. Epub 2012 Dec 12.

BACKGROUND: Previous studies have reported that epidermal growth factor receptor (EGFR) mutation in tumor tissue and peripheral blood can predict the response to EGFR tyrosine kinase inhibitor (TKI) in non-small cell lung cancer (NSCLC). However, the heterogeneity of the...

Aerobiologia (Bologna). 2013 Jun;29(2):161-173. doi: 10.1007/s10453-012-9270-2. Epub 2012 Aug 01.

The understanding of airborne pollen transportation is crucial for the reconstruction of the paleoenvironment. Under favorable conditions, a considerable amount of long-distance-transported pollen can be deposited far from its place of origin. In extreme arid regions, in most cases,...

Outcome of endoscopic transsphenoidal surgery in combination with somatostatin analogues in patients with growth hormone producing pituitary adenoma.

OBJECTIVE: To determine the efficacy of endoscopic surgery in combination with long-acting somatostatin analogues (SSAs) in treating patients with growth hormone (GH)-secreting pituitary tumor.METHODS: We performed retrospective analysis of 133 patients with GH producing pituitary adenoma who underwent pure...

Pure red phosphorescent organic light-emitting diodes made of iridium(III) complex with thiophene-quinoline ligand.

J Nanosci Nanotechnol. 2013 Dec;13(12):8007-10. doi: 10.1166/jnn.2013.8152.

A cyclometalated iridium(II) complex, bis(2-thiophen-2-yl-quinolinato)(acetoacetonate)iridium(II) [(tq)2Ir(III)(acac)] was synthesized for use in phosphorescent organic light-emitting diodes. The photophysical and electrochemical properties of the iridium(Ill) complex were characterized by UV-visible absorption, photoluminescence, and cyclic voltammetry. The maximum UV-visible absorption of (tq)2Ir(acac)...

Relational diversity promotes cooperation in prisoner's dilemma games.

PLoS One. 2014 Dec 04;9(12):e114464. doi: 10.1371/journal.pone.0114464. eCollection 2014.

Relational diversity can be characterized by heterogeneous distributions of tie strengths in social networks and this diversity is present not only among humans, but throughout the animal world. We account for this observation by analyzing two network datasets from...
