Examining Motivator Factors of STEM Undergraduate Persistence through Two-Factor Theory

Stem education interventions

Chen R, Pedraza L.
GSID: hKGgDAH4-ZAJ
L Pedraza, R Chen - The Journal of Higher Education, 2022 - Taylor & Francis

This study investigates undergraduate STEM persistence through two-factor theory. Using nationally representative data and multinomial regression, we conceptualize known determinants of persistence as hygiene and motivator factors to test the persistence outcomes among college students who majored in STEM:...

Development of a compact vertical-cavity surface-emitting laser end-pumped actively Q-switched laser for laser-induced breakdown spectroscopy.

The Review of scientific instruments

Li S, Liu L, Chen R, Nelsen B, Huang X, Lu Y, Chen K.
PMID: 27036765
Rev Sci Instrum. 2016 Mar;87(3):033114. doi: 10.1063/1.4944856.

This paper reports the development of a compact and portable actively Q-switched Nd:YAG laser and its applications in laser-induced breakdown spectroscopy (LIBS). The laser was end-pumped by a vertical-cavity surface-emitting laser (VCSEL). The cavity lases at a wavelength of...

Anti-Programmed Cell Death (PD)-1 Immunotherapy for Malignant Tumor: A Systematic Review and Meta-Analysis.

Translational oncology

Chen R, Peng PC, Wen B, Li FY, Xie S, Chen G, Lu J, Peng Z, Tang SB, Liang YM, Deng X.
PMID: 26947879
Transl Oncol. 2016 Feb;9(1):32-40. doi: 10.1016/j.tranon.2015.11.010.

This systematic review and meta-analysis evaluated anti-programmed cell death (PD)-1 immunotherapy (nivolumab or pembrolizumab) for overall efficacy, safety, and effective dose relative to standard chemotherapy or other conventional drugs in the treatment of malignant tumors. We searched the following...

Enhancing Nitrate Removal from Freshwater Pond by Regulating Carbon/Nitrogen Ratio.

Frontiers in microbiology

Chen R, Deng M, He X, Hou J.
PMID: 28943869
Front Microbiol. 2017 Sep 08;8:1712. doi: 10.3389/fmicb.2017.01712. eCollection 2017.

Nitrogen accumulation is a serious environmental problem in freshwater ponds, which can lead to massive death of fish and shrimps as well as the eutrophication. The removal of nitrate by regulating the carbon to nitrogen (C/N) ratio and the...

A Stereo Dual-Channel Dynamic Programming Algorithm for UAV Image Stitching.

Sensors (Basel, Switzerland)

Li M, Chen R, Zhang W, Li D, Liao X, Wang L, Pan Y, Zhang P.
PMID: 28885547
Sensors (Basel). 2017 Sep 08;17(9). doi: 10.3390/s17092060.

Dislocation is one of the major challenges in unmanned aerial vehicle (UAV) image stitching. In this paper, we propose a new algorithm for seamlessly stitching UAV images based on a dynamic programming approach. Our solution consists of two steps:...

Modulation of photonic nanojets generated by microspheres decorated with concentric rings.

Optics express

Wu MX, Huang BJ, Chen R, Yang Y, Wu JF, Ji R, Chen XD, Hong MH.
PMID: 26367667
Opt Express. 2015 Jul 27;23(15):20096-103. doi: 10.1364/OE.23.020096.

A novel design of decorating microsphere surface with concentric rings to modulate the photonic nanojet (PNJ) is investigated. By introducing the concentric ring structures into the illumination side of the microspheres, a reduction of the full width at half...

Zinc finger RNA-binding protein promotes non-small-cell carcinoma growth and tumor metastasis by targeting the Notch signaling pathway.

American journal of cancer research

Zhang H, Zhang CF, Chen R.
PMID: 28979805
Am J Cancer Res. 2017 Sep 01;7(9):1804-1819. eCollection 2017.

Metastatic non-small-cell lung carcinoma (NSCLC) is typically incurable. The development of anti-metastatic therapies is hampered because the mechanisms regulating metastasis in NSCLC are not well known. Currently, there is no effective treatment for NSCLC once it has progressed to...

Inferring Human Activity in Mobile Devices by Computing Multiple Contexts.

Sensors (Basel, Switzerland)

Chen R, Chu T, Liu K, Liu J, Chen Y.
PMID: 26343665
Sensors (Basel). 2015 Aug 28;15(9):21219-38. doi: 10.3390/s150921219.

This paper introduces a framework for inferring human activities in mobile devices by computing spatial contexts, temporal contexts, spatiotemporal contexts, and user contexts. A spatial context is a significant location that is defined as a geofence, which can be...

Ionically dispersed Fe(ii)-N and Zn(ii)-N in porous carbon for acidic oxygen reduction reactions.
