Specification-Based Grading Resources For Openstax College Physics (Ggc), Edward Forringer Apr 2019

Specification-Based Grading Resources For Openstax College Physics (Ggc), Edward Forringer

Physics and Astronomy Ancillary Materials

This collection of ancillary materials for Introductory Biology was created under a Round Eleven Mini-Grant for Ancillary Materials Creation and Revision. Included are the following resources to assist a faculty member in implementing specification grading in an introductory physics course using OpenStax College Physics:

  • Specification Grading Guide
  • Specification Documents
  • Quizzes
  • Practice Final Exam

Author's Description:

"Rather than grading each assignment with partial credit and then taking a weighted average of your assignments to find a grade, this course uses a set of course expectations called “specifications” (spec for short). Each spec has an associated quiz. Some specifications are designated ...


Temporal And Spatial Scaling Of Dissipation Under Non-Breaking Surface Waves, Mingming Shao, Brian K. Haus, Darek Bogucki, Mohammad Barzegar Jan 2019

Temporal And Spatial Scaling Of Dissipation Under Non-Breaking Surface Waves, Mingming Shao, Brian K. Haus, Darek Bogucki, Mohammad Barzegar

Supplementary Data and Tools

This dataset is associated to the NSF OCE/Physical Oceanography funded project “Laboratory Investigation of Turbulence Generation by Surface Waves”. There are three papers in preparation that will refer to data contained within this archive. The overarching goal of this project was to address a significant knowledge gap regarding the turbulent dissipation of non-breaking surface waves. To accomplish this, a comprehensive study in the SUrge-STructure-Atmosphere-INteraction (SUSTAIN) wind-wave laboratory at the University of Miami was conducted. A combination of established measurement approaches (Particle Image Velocimetry (PIV) and Vertical Microstructure Profiler (VMP)) and new technologies (Optical Turbulence Sensor (OTS)) have been used ...


2d Ion Temperature Maps From Twins Ena Data: Idl Scripts, Amy Keesee, Earl Scime, Anna Zaniewski, Roxanne Katus Jan 2019

2d Ion Temperature Maps From Twins Ena Data: Idl Scripts, Amy Keesee, Earl Scime, Anna Zaniewski, Roxanne Katus

Physics Scholarship

Energetic neutral atom (ENA) flux from the NASA TWINS mission (and previously the MENA instrument on the NASA IMAGE mission) is projected along the line of sight to the equatorial plane in GSM coordinates. A Maxwellian fit is used to calculate the ion temperature in each equatorial plane bin, creating 2D maps of ion temperatures. The files are IDL .pro scripts that can be read using a text editor. IDL software is required to run. The primary script is twins_master.pro. The scripts call other scripts that were developed by the TWINS mission team as well as publicly available IDL ...


Spacetime Groups, Ian M. Anderson, Charles G. Torre Jan 2019

Spacetime Groups, Ian M. Anderson, Charles G. Torre

Publications

A spacetime group is a connected 4-dimensional Lie group G endowed with a left invariant Lorentz metric h and such that the connected component of the isometry group of h is G itself. The Newman-Penrose formalism is used to give an algebraic classification of spacetime groups, that is, we determine a complete list of inequivalent spacetime Lie algebras, which are pairs (g,η), with g being a 4-dimensional Lie algebra and η being a Lorentzian inner product on g. A full analysis of the equivalence problem for spacetime Lie algebras is given which leads to a completely algorithmic solution to ...

Bioinformatics Software Design Projects

Cholesterol is carried and transported through bloodstream by lipoproteins. There are two types of lipoproteins: low density lipoprotein, or LDL, and high density lipoprotein, or HDL. LDL cholesterol is considered “bad” cholesterol because it can form plaque and hard deposit leading to arteries clog and make them less flexible. Heart attack or stroke will happen if the hard deposit blocks a narrowed artery. HDL cholesterol helps to remove LDL from the artery back to the liver.

Traditionally, particle counts of LDL and HDL plays an important role to understanding and prediction of heart disease risk. But recently research suggested that ...


Isotope Effect On Electron-Phonon Interaction In Multiband Superconductor Mgb2, Adam Kaminski, Daixiang Mou, Paul C. Canfield, Serguei Budko, Lunan Huang, Valentin Taufour, Yun Wu, Soham Manni Apr 2016

Isotope Effect On Electron-Phonon Interaction In Multiband Superconductor Mgb2, Adam Kaminski, Daixiang Mou, Paul C. Canfield, Serguei Budko, Lunan Huang, Valentin Taufour, Yun Wu, Soham Manni

Ames Laboratory Datasets

We investigate the effect of isotope substitution on electron-phonon interaction in multi-band superconductor MgB$_2$ using tunable laser based Angle Resolved Photoemission Spectroscopy. The kink structure around 70 meV in Sigma band, which is caused by electron coupling to E_2g phonon mode, is shifted to higher binding energy by ~3.5 meV in Mg^10B2. The changes of the kink energy reported here suggest that the anharmonicity of the E2g phonon in MgB2 is very small, which reopens the debate about the unusually small isotope coefficient in this material. These results are the benchmark for investigation of isotope effect in ...

Discovery Of Dirac Node Arcs In Ptsn4, Adam Kaminski, Paul C. Canfield, Serguei Bud'ko, Daixiang Mou, Eundeok Mun, Yun Wu, Lunan Huang, Yongbin Lee, Duane D. Johnson, Linlin Wang Jan 2016

Discovery Of Dirac Node Arcs In Ptsn4, Adam Kaminski, Paul C. Canfield, Serguei Bud'ko, Daixiang Mou, Eundeok Mun, Yun Wu, Lunan Huang, Yongbin Lee, Duane D. Johnson, Linlin Wang

Ames Laboratory Datasets

In topological quantum materials the conduction and valence bands are connected at points (Dirac/Weyl semimetals) or along lines (Line Node semimetals) in the momentum space. Numbers of studies demonstrated that several materials are indeed Dirac/Weyl semimetals. However, there is still no experimental confirmation of materials with line nodes, in which the Dirac nodes form closed loops in the momentum space. Here we report the discovery of a novel topological structure - Dirac node arcs - in the ultrahigh magnetoresistive material PtSn4 using laser-based angle-resolved photoemission spectroscopy (ARPES) data and density functional theory (DFT) calculations. Unlike the closed loops of line ...


Imaging The Magnetic Nano-Domains In Nd2fe14b, Adam Kaminski, Daixiang Mou, Paul C. Canfield, Valentin Taufour, Lunan Huang, Serguei Budko, Benjamin Schrunk, Tey Lamichhane Jan 2016

Imaging The Magnetic Nano-Domains In Nd2fe14b, Adam Kaminski, Daixiang Mou, Paul C. Canfield, Valentin Taufour, Lunan Huang, Serguei Budko, Benjamin Schrunk, Tey Lamichhane

Ames Laboratory Datasets

We study magnetic domains in Nd2Fe14B single crystals using high resolution magnetic force microscopy (MFM). Previous MFM studies and small angle neutron scattering experiments suggested the presence of nano-scale domains in addition to optically detected micrometer-scale ones. We find, in addition to the elongated, wavy nano-domains reported by a previous MFM study, that the micrometer size, star shape fractal pattern is constructed of an elongated network of nano-domains ~20 nm in width, with resolution-limited domain walls thinner than 2 nm. While the microscopic domains exhibit significant resilience to an external magnetic field, some of the nano domains are sensitive to ...
