Instruction and assessment of information literacy among STEM majors

STEM education program evaluation

Scharf D.
GSID: hh3S5Fl9veAJ
D Scharf - 2014 IEEE Integrated STEM Education Conference, 2014 - ieeexplore.ieee.org

The ability to find, use, and communicate information effectively is a critical competency for 21st century engineers. Thus it is an important element in retention, graduation, and placement of professional engineers. This study found scaffolded, engaging instruction resulted in...

3D Surface Reconstruction of Plant Seeds by Volume Carving: Performance and Accuracies.

Frontiers in plant science

Roussel J, Geiger F, Fischbach A, Jahnke S, Scharr H.
PMID: 27375628
Front Plant Sci. 2016 Jun 07;7:745. doi: 10.3389/fpls.2016.00745. eCollection 2016.

We describe a method for 3D reconstruction of plant seed surfaces, focusing on small seeds with diameters as small as 200 μm. The method considers robotized systems allowing single seed handling in order to rotate a single seed in...

Under-flame Reaction of Sulfur-containing Amino Acids by a Hydrogen-Oxygen Flame.

Bioscience, biotechnology, and biochemistry

Nomoto S, Shimoyama A, Shiraishi S, Seno T, Sahara D.
PMID: 27392552
Biosci Biotechnol Biochem. 1998;62(4):643-9. doi: 10.1271/bbb.62.643.

Methionine was subjected to a flame-induced reaction in water or in an aqueous formic acid solution by using a hydrogen (50%)-oxygen (50%), hydrogen (87%)-oxygen (13%) and hydrogen diffusion flame. Besides the already-known stepwise oxidation by a hydroxyl radical, the...

Citizen crowds and experts: observer variability in image-based plant phenotyping.

Plant methods

Giuffrida MV, Chen F, Scharr H, Tsaftaris SA.
PMID: 29449872
Plant Methods. 2018 Feb 09;14:12. doi: 10.1186/s13007-018-0278-7. eCollection 2018.

BACKGROUND: Image-based plant phenotyping has become a powerful tool in unravelling genotype-environment interactions. The utilization of image analysis and machine learning have become paramount in extracting data stemming from phenotyping experiments. Yet we rely on observer (a human expert)...

Treating Atrial Fibrillation With Cryoballoon Technology.

Journal of atrial fibrillation

Altmann DR, Knecht S, Sticherling C, Ammann P, Schaer B, Osswald S, Kühne M.
PMID: 28496735
J Atr Fibrillation. 2012 Apr 14;4(6):486. doi: 10.4022/jafib.486. eCollection 2012.

Cryoballoon ablation has emerged as a novel tool to perform pulmonary vein isolation. The aim of this paper is to review the advantages, drawbacks as well as possible complications and clinical outcomes of this technology and to discuss some...

Targeting tumor-necrosis factor receptor pathways for tumor immunotherapy.

Journal for immunotherapy of cancer

Schaer DA, Hirschhorn-Cymerman D, Wolchok JD.
PMID: 24855562
J Immunother Cancer. 2014 Apr 15;2:7. doi: 10.1186/2051-1426-2-7. eCollection 2014.

With the success of ipilimumab and promise of programmed death-1 pathway-targeted agents, the field of tumor immunotherapy is expanding rapidly. Newer targets for clinical development include select members of the tumor necrosis factor receptor (TNFR) family. Agonist antibodies to...

Automated and manufacturer independent assessment of the battery status of implanted cardiac pacemakers by electrocardiogram analysis.

Conference proceedings : ... Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual Conference

Schreier G, Hayn D, Kollmann A, Scherr D, Lercher P, Rotman B, Klein W.
PMID: 17271607
Conf Proc IEEE Eng Med Biol Soc. 2004;2006:76-9. doi: 10.1109/IEMBS.2004.1403094.

According to international standards, cardiac pacemakers have to indicate the status of their batteries upon magnet application by specific stimulation patterns. The purpose of this study has been to assess whether this concept can be used as a basis...

What effect do attempts to lose weight have on the observed relationship between nutrition behaviors and body mass index among adolescents?.

The international journal of behavioral nutrition and physical activity

Utter J, Scragg R, Ni Mhurchu C, Schaaf D.
PMID: 17880722
Int J Behav Nutr Phys Act. 2007 Sep 19;4:40. doi: 10.1186/1479-5868-4-40.

BACKGROUND: Little research has given consideration to how people's weight control behaviors may moderate the relationships between nutrition and body mass index (BMI) in large cross-sectional studies. The objective of the current study is to determine how attempts to...

Generation of scaled protogalactic seed magnetic fields in laser-produced shock waves.

Nature

Gregori G, Ravasio A, Murphy CD, Schaar K, Baird A, Bell AR, Benuzzi-Mounaix A, Bingham R, Constantin C, Drake RP, Edwards M, Everson ET, Gregory CD, Kuramitsu Y, Lau W, Mithen J, Niemann C, Park HS, Remington BA, Reville B, Robinson AP, Ryutov DD, Sakawa Y, Yang S, Woolsey NC, Koenig M, Miniati F.
PMID: 22281596
Nature. 2012 Jan 25;481(7382):480-3. doi: 10.1038/nature10747.

The standard model for the origin of galactic magnetic fields is through the amplification of seed fields via dynamo or turbulent processes to the level consistent with present observations. Although other mechanisms may also operate, currents from misaligned pressure...

Body mass index and percent body fat in a New Zealand multi-ethnic adolescent population.

International journal of pediatric obesity : IJPO : an official journal of the International Association for the Study of Obesity

Sluyter JD, Schaaf D, Scragg RK, Plank LD.
