## Finding missing citation entries in an org-file
| categories: | tags: | View Comments
Today we consider how to find citations in a document that have no corresponding entries in a bibtex file. There are a couple of pieces to this which we work out in stages below. First, we specify the bibtex file using a bibliogr... | |

# Review the experimental question and hypothesis. Which statement best explains why the hypothesis is testable? Question: How does the amount of water individuals drink everyday affect the number of facial blemishes they receive every month? Hypothesis: If the amount of water people drink everyday affects the concentr... | |
# Why do we think of group compositions as multiplication?
This has bothered me for some time: The composition in a group is usually denoted $xy$ or $x\cdot y$. Powers (note the word) are denoted by $x^n$, inverses by $x^{-1}$, and the neutral element by $1$.
Someone clearly seemed to think of multiplication when the... | |

# Simulate, Analyze, Measure Electronics (SAME)
In Electronics, there are 3 perspectives of a circuit
1. Simulation - simulate to observe what the real world results should be like
2. Analysis - using mathematical models to analyze and predict the results
3. Measurement - prototype the circuit and measure
If the resu... | |
# High-resolution tip-enhanced Raman scattering probes sub-molecular density changes
## Abstract
Tip-enhanced Raman spectroscopy (TERS) exhibits new selection rule and sub-nanometer spatial resolution, which is attributed to the plasmonic near-field confinement. Despite recent advances in simulations of TERS spectra ... | |

Abstract: Since it was proposed in 2015 as a generalization of integral properties, the division... | |
Does there exist anywhere a comprehensive list of small genus modular curves $X_G$, for G a subgroup of GL(2,Z/(n))$? (say genus <= 2), together with equations? I'm particularly interested in genus one cases, and moreso in split/non-split cartan, with or without normalizers. Ken Mcmurdy has a list here for$X_0(N)$, and... |
