Technical Writing Tips: Abbreviations and Acronyms

It’s common in science and engineering to use abbreviations and acronyms to shorten long words or terms. This comes in not only when communicating with others, but also in one’s internal communication. In our lab, we end up with tons and tons of files and directories full of simulation data. We usually give them cryptic names. “R0.1mmCV0.4x” or “CI250V5” or worse. Typing out long names all of the time is laborious, and we generally know what our own abbreviations mean. This comes into play with notes, too. I might write down CV instead of conduction velocity, LAD instead of left anterior descending coronary artery, or APD instead of action potential duration, or the more ambiguous “duration.” When thinking or writing about different sets of experimental parameters, I may refer to things with labels that are nonsensical without explanation. It’s an issue of practicality.

When communicating with outsiders, however, abbreviations can be a problem. They must be kept to a minimum in papers, abstracts, and posters. Even things that are talked about all the time in the field must be defined, as you can never assume that someone knows them. I’m working on a manuscript now, and I had to go back, count instances of abbreviations, decide which ones were worth using (used often) and which had to be spelled out (used infrequently). In retrospect — and here’s the writing tip — I should have written everything out in the manuscript to start with. It would have been easier to go back later with search-and-replace to abbreviate the most-used terms.

A blur of a day

I awoke once more at around 05:00, without an alarm, but was a bit slow to get moving. I felt heavy, like I wasn’t meant to be up. No matter, I caught up on my RSS feeds, did my morning pushups and crunches, and remembered that I have today off from running because it’s the weekend. In reality, I should have run anyway since I skipped a few days this week, but I just wasn’t feeling up to it.

I’ve been setting up and running simulations all day. This takes a bit of time, because I’m running the simulations remotely on our cluster. I have to log in, set up the simulation, submit it, wait for it to finish, zip up the data files (they’re quite big but compress very well), copy them over, load them, play the sequence in the data viewer, and then discover yet again that something’s not quite right with the timing. I’m trying to initiate a spiral wave, and I fear that perhaps the model I’m using is too small. My excitable gap is too narrow. The problem is, this mesh must be relatively fine. Therefore, if I make it larger, my required computational power will increase quite a bit, slowing me down further. I’ve got another try running right now, and I think I’m getting close to the right timing. I’ll check it in the morning and find out.

In the gaps of time between simulation stuff I’ve been playing some Prince of Persia / Sands of Time, reading blogs, pruning my RSS feed list, making some phone calls, eating breakfast, brunch, lunch (with a margarita!), and dinner. Oh yes, skipping exercise and eating more. This is doing me a world of good.

The blog associated with HubMed was full of Mac-friendly goodness today, including links to a bunch of free games for Mac OS X. Most of them are available under the GNU General Public License (a.k.a GPL, free as in speech) and are originally Linux games. One of my favorites, which I played on Linux first, is Frozen Bubble. I have problems copying it to my applications folder for some reason, and have to play it off of the disk image. I was also reminded by the presence of Goban on that list that I should try picking up Go again. But not tonight. Maybe I’ll order a Go book from Amazon once their gift certificiate payment scheme is back up and running. By the way, I hope none of you have sustained any injuries during the post-Thanksgiving commercial feeding frenzy…

I know by this time you must be dying to see the stats for the day. Agonize no longer:

Sleep Water Exercise Coffee Green Tea Alcohol
8 h 2.5 L 0 min 2 cup(s) 4 cup(s) 1 drink(s)

If I’m going to get eight hours of sleep again, I should get on with my pre-sleep reading, and then crash. Ta ta for now.

The All-Encompassing Cardiac Electro-whiz-bang Wiki thing!

I love wikis. I love the idea. I love many of the implementations. We use one in my research lab, I use one for my home page, I set a few up for coordination following Hurricane Katrina, and so on. The internal lab wiki has saved me hours and countless hours of having to re-explain something. It’s saved Rob from having to set up some other sort of distribution of software. Now that I’m using access control lists, it provides and easy way for the lab to make files and information readily available to select people, and to the world. It’s a fantastic collaboration tool, whose power is perhaps epitomized by the king of wikis, Wikipedia. Last week, I decided that there was a nice big hole in the Internets where something should be.

A wiki for the entire field of cardiac electrophysiology. And here it is:

It’s in its infancy now, but I intend to populate it further. It will truly take off when enough people watch it, update it, point their students at it, make it their homepage, tell their friends, post conference notes, list blogs, share research data, and use it to keep abreast of the field.

The age of person-generated content is at hand. (As opposed to organization-generated content, I suppose)

Everbody wants a log

Recently, I started logging all of my work hours. Due to hurricane shenanigans, the plots so far have been rather odd-looking.

As the captions in my gallery say, these are strictly time spent on project and work logistics. These do not include break time. They do not include personal logistics, even those that are tangentially related to or supportive of my work-related activities. This is just time spent writing, setting up simulations, getting necessary documents, sending necessary documents, etc. My total time for September was 34.95 hours. Total time for October was 47.33. This despite the fact that I spent almost two weeks on moving-related activities. I predict that my November numbers will be much higher, since it’s the first month not totally screwed up by Hurricane Katrina-related activities. Total hours for November may be as high as 100 or more.

This logging has been very interesting for me to look back on. As a result, I’m going to start logging other aspects of my life. Minutes of exercise per day. Hours of sleep per day. Volumes of water, of caffeinated beverages, etc consumed per day. I’m debating posting the stats daily, in order to encourage me to blog more. I’m also adding “Blog post” to my nightly checklist, in order to encourage me to keep posting. It’s easy to let a blog atrophy. I have high aims for this blog, so I can’t let that carry on the way it’s been going.

Comments and complaints are welcome, as long as you don’t blog-spam me. That’s been quite a problem lately.
