Perceived abilities or academic interests? Longitudinal high school science and mathematics effects on postsecondary STEM outcomes by gender and race

Stem education interventions

Perez-Felkner L, Zhao T.
GSID: pTitb_d8HXEJ
T Zhao, L Perez-Felkner - International Journal of STEM Education, 2022 - Springer

Previous literature has examined the relationship between high school students' postsecondary STEM major choices and their prior interest and perceived ability in mathematics. Yet, we have limited understanding of whether and how perceived ability and interest in science and...

Formal and informal mentorships: A comparison on mentoring functions and contrast with nonmentored counterparts

program design

Chao GT.
GSID: hF7f-Ph6JZsJ
GT Chao, P Walz, PD Gardner - Personnel psychology, 1992 - Wiley Online Library

Research on mentorships has suffered from fragmentation of key issues; specifically, type of mentoring relationship, functions served by the mentor, and outcomes of the mentoring …

Optimization of wavefront-coded infinity-corrected microscope systems with extended depth of field.

Biomedical optics express

Zhao T, Mauger T, Li G.
PMID: 24010008
Biomed Opt Express. 2013 Jul 31;4(8):1464-71. doi: 10.1364/BOE.4.001464. eCollection 2013.

The depth of field of an infinity-corrected microscope system is greatly extended by simply applying a specially designed phase mask between the objective and the tube lens. In comparison with the method of modifying the structure of objective, it...

A dynamic material discrimination algorithm for dual MV energy X-ray digital radiography.

Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine

Li L, Li R, Zhang S, Zhao T, Chen Z.
PMID: 27239987
Appl Radiat Isot. 2016 Aug;114:188-95. doi: 10.1016/j.apradiso.2016.05.018. Epub 2016 May 16.

Dual-energy X-ray radiography has become a well-established technique in medical, industrial, and security applications, because of its material or tissue discrimination capability. The main difficulty of this technique is dealing with the materials overlapping problem. When there are two...

Hydrogen sulfide intervention in focal cerebral ischemia/reperfusion injury in rats.

Neural regeneration research

Li XJ, Li CK, Wei LY, Lu N, Wang GH, Zhao HG, Li DL.
PMID: 26199610
Neural Regen Res. 2015 Jun;10(6):932-7. doi: 10.4103/1673-5374.158353.

The present study aimed to explore the mechanism underlying the protective effects of hydrogen sulfide against neuronal damage caused by cerebral ischemia/reperfusion. We established the middle cerebral artery occlusion model in rats via the suture method. Ten minutes after...

Difference in Leukocyte Composition between Women before and after Menopausal Age, and Distinct Sexual Dimorphism.

PloS one

Chen Y, Zhang Y, Zhao G, Chen C, Yang P, Ye S, Tan X.
PMID: 27657912
PLoS One. 2016 Sep 22;11(9):e0162953. doi: 10.1371/journal.pone.0162953. eCollection 2016.

There are sex differences in many inflammatory and immune diseases, and the differences tend to diminish after menopause. The underlying reasons are unclear, but sex hormone levels are likely to be an important factor. Blood leukocyte count and composition...

2,2,2-Trifluoroethylation of Styrenes with Concomitant Introduction of a Hydroxyl Group from Molecular Oxygen by Photoredox Catalysis Activated by Visible Light.

Organic letters

Li L, Huang M, Liu C, Xiao JC, Chen QY, Guo Y, Zhao ZG.
PMID: 26361093
Org Lett. 2015 Oct 02;17(19):4714-7. doi: 10.1021/acs.orglett.5b02177. Epub 2015 Sep 11.

The visible-light-induced photoredox difunctionalization reactions of styrenes with 1,1,1-trifluoro-2-iodoethane under an oxygen atmosphere in the presence of water give γ-trifluoromethyl alcohols. In this radical reaction, the oxygen atom in the product originates from molecular oxygen, and water is shown...

Machine Learning Estimation of Atom Condensed Fukui Functions.

Molecular informatics

Zhang Q, Zheng F, Zhao T, Qu X, Aires-de-Sousa J.
PMID: 27491791
Mol Inform. 2016 Feb;35(2):62-9. doi: 10.1002/minf.201500113. Epub 2015 Nov 24.

To enable the fast estimation of atom condensed Fukui functions, machine learning algorithms were trained with databases of DFT pre-calculated values for ca. 23,000 atoms in organic molecules. The problem was approached as the ranking of atom types with...
