Live Long and Prosper
For regular readers of the New England Journal of High Energy Physics, I need no introduction. If you’re not familiar with that publication, Greetings I am Dr. Sheldon Lee Cooper B.S., M.S., M.A., Ph.D., Sc.D. I am a senior theoretical particle physicist at Caltech focusing on M-Theory or in layman's terms String Theory. I am not one who usually partakes in social networking for I seldom have a desire to do so, but I feel this blog will add great consistency to my Daily Social Interactions. I am fond of comic books, costumes, roleplaying games, video games, customizable card games, action figures, fantasy, and science fiction, specifically Battlestar Galactica, Doctor Who, Stargate, Star Trek, Star Wars, and Firefly, although I strongly dislike Babylon 5 for reasons that need no explanation whatsoever. I will leave my ask box open but does not mean I wish for you to slaughter me with your brainless inquisitions. I will record my D.S.I. at the end of each day via a "Text Post."

If you don’t mind, that will be the Joke of the Day! Perhaps I should be open to people submitting jokes…

Hello followers. Today, I commenced my week long lectures on the concept of topological insulators. To my surprise, not a single student found my topology puns to have the slightest bit of amusement. Tough crowd. Perhaps the students tomorrow will have a better sense of humor. Apart from the complete failure of opening with a joke, the students were well behaved throughout the lecture. I did, however, sense a few of the students giving me inappropriate hand gestures as I had my back turned to them. I disregarded it. I spent the rest of my time at work prepping the powerpoint notes for tomorrow. After work, I took the bus to Jerry’s Junction for the model train show. It was rather remarkable. They will be having another show next Monday, which I will surely be attending. As per the remainder of my day, I watched the conferences from E3 that I recorded on the DVR. In respect to the several other titles, I am most looking forward to Halo 4. It will definitely be a nice addition to our Wednesday night antics. Well, it’s time for bed. Goodnight. That is all for now.

Dr. Sheldon Cooper’s Joke of the Day: June 4, 2012
Sherlock Holmes and Dr Watson were going camping. They pitched their tent under the stars and went to sleep. Sometime in the middle of the night, Holmes woke Watson up and said, “Watson, look up at the stars, and tell me what you see.” Watson replied, “I see millions and millions of stars.” Holmes said, “And what do you deduce from that?” Watson replied, “Well, if there are millions of stars, and if even a few of those have planets, it’s quite likely there are some planets like Earth out there. And if there are a few planets like Earth out there, there might also be life.” And Holmes said, “Watson, you idiot, it means that somebody stole our tent.”

Quantitative Methods for Comparing Different HVAC Control Schemes.
Authors: Anil Aswani, Neal Master, Jay Taneja, Andrew Krioukov, David Culler, Claire Tomlin
Experimentally comparing the energy usage and comfort characteristics of different controllers in heating, ventilation, and air-conditioning (HVAC) systems is difficult because variations in weather and occupancy conditions preclude the possibility of establishing equivalent experimental conditions across the order of hours, days, and weeks. This paper is concerned with defining quantitative metrics of energy usage and occupant comfort, which can be computed and compared in a rigorous manner that is capable of determining whether differences between controllers are statistically significant in the presence of such environmental fluctuations. Experimental case studies are presented that compare two alternative controllers (a schedule controller and a hybrid system learning-based model predictive controller) to the default controller in a building-wide HVAC system. Lastly, we discuss how our proposed methodology may also be able to quantify the efficiency of other building automation systems.

Hello. After waking up at 7:00 and taking a soothing shower, I spent my morning watching Stargate as I re-laced my walking shoes. We went to the park for the majority of the afternoon. I made sure to arrive before 12:30 so I could purchase an ice cream cone from the ice cream vendor. We did not bring our kites because Raj did not join us. It is pointless to go one on one, especially against someone as amateur as Leonard. No offense. Once we went back home, I took my second shower of the day. As per the remainder of the day, I have been preparing my lecture on the concept of topological insulators that I will be giving Monday-Friday at the university. I hope the students are in a good mood for my opening humorous topology puns! Tomorrow after work, I will be going to a model train show at Jerry’s Junction. Well, I’m going to finish writing these last few notes before turning in. That is all for now.

Matter stability in modified teleparallel gravity.
Authors: A. Behboodi, S. Akhshabi, K. Nozari
We study the matter stability in modified teleparallel gravity or
theories. We show that there is no Dolgov-Kawasaki instability in these types of modified teleparallel gravity theories. This give the
counterparts because from the stability point of view there isn’t any limit on the form of functions that can be chosen.
Dr. Sheldon Cooper’s Joke of the Day: June 3, 2012
Two hunters are out in the woods when one of them collapses. He doesn’t seem to be breathing and his eyes are glazed. The other guy whips out his phone and calls the emergency services. He gasps, “My friend is dead! What can I do?” The operator says “Calm down. I can help. First, let’s make sure he’s dead.” There is a silence, then a gun shot is heard. Back on the phone, the guy says, “OK, now what?”

The gravitational cusp anomalous dimension from AdS space.
Authors: D. J. Miller, C. D. White
Recently a new picture has been developed for examining Wilson lines, and the corresponding anomalous dimensions which govern their renormalization properties. By making a particular coordinate transform, the calculation of the cusp anomalous dimension in QED or QCD can be related to the energy of a pair of static charges in Euclidean Anti-de-Sitter (AdS) space. This paper shows how the same picture can be used to describe Wilson lines in quantum gravity. We show how the relevant cusp anomalous dimension (which has recently been shown to be one loop exact) can be obtained using the Newtonian limit of General Relativity. We also show how both the QED and gravity cases emerge as special cases of a general formulation, and that a continuous parameter exists which interpolates between them. The results may be useful in examining the relations between gauge and gravity theories.
