Phenomenon#135

Last week, while working in library stack, one of the students suggested that, library stacks would be a great location for a Hollywood ghost story, at least a thriller. I agree. Imagine a BIG hall full of rows and rows and rows (and then some more rows) of books. Imagine 4 floors like that. I mean, it’s a heaven for bibliophile (and believe me, if you believe the accounts, anything goes in stacks), but imagine moving between those silent volumes when you are absolutely alone on the whole floor the size of half a cricket ground. Brrr!!!!

Anyways, that reminded me of Phenomenon #135. Room #135 is the lab where I work on this fantastic machine. Last month, I entered the lab, and was pretty shocked to see all my lab-mates looking at me like I just walked into somebody’s home through window. The reason for their expression? Apparently, for some days before that, the door used to open, without anybody actually entering.

The same day, at 11 in night, me and my roomie went to the building to get some printouts. I was pretty surprised to see the lights in #135 on, but nobody could be seen in the lab (we are pretty particular about the whole “Save electricity” thingy). Well, we started the printouts, and went to other building for some work there. While coming back, we decided to take the side door. We just just came near the door, and POOF, the lights go on! We again ignore this and go back to the printer to finish our work. While coming back, I was curious, and checked again in #135, the lights were off!

Considering that we found no cleaners, in fact nobody else on the whole floor to account for this, I have temporarily named these encounters of strange kind, “Phenomenon #135”.

Unfortunately, further investigation in this was interrupted by my exams coming, and now we are moving to other building…

Finally....

Finally, the finals are over.

Fall’05 is over. Overall, it was an eventful (for lack of stronger word) term. Feels good to be back in school, feels bad to be not able to keep the work at home. Anyways, three more to go, and I am sure the next term will be different (better surely).

So, here I am, sitting the coffee house, trying to finish the pending tasks (not school related). Come 20th, I will be on my way to San Jose.

Spring’06 starts on 11th Jan. My class starts on 3rd Jan. So, see you on 4th, school!!!

One Down, (minimum) Two more to go

Finally… had last stat class yesterday. Had last imaging class today. Have only 2 classes remaining, one of them a guest lecture.

The term is getting over. But that does not mean the work load is over. Have a project due next Monday (for which the code is not working right now), got exams next Tuesday and Saturday. Yes, that is not a typo! I have exam on Saturday at 2 to 5 p.m. (sob sob)

Hope everything goes fine. Wish me luck guys!

Till that time, its F.R.I.E.N.D.S to rescue.

Of Barrel Rolls and Ethics

One of the students in my class came out with pretty complex question. Call it ethics, call it anything…

Suppose you are flying a executive jet like Embraer or say, Sessna, full of passangers. When you are in the flight, your co-pilot offers you $3 million (or something hefty like that) if you perform a Barrel Roll. Assuming that he is capable of paying the amount decided and he is going to pay you if you win the dare, what would you do? (Remember that the barrel roll in aircraft is not a pleasant sensation to anybody, and you are carrying your employer along with some other people.)
Now suppose you are the employer. Will you fire your pilot after he has subjected you to his fancy maneuver, just for a paltry sum of $3 million?

Class: BME 201 (Electrobio)
Topic: Ethics of Animal Experiments

We are discussing whether there should be different treatment for violators against different animals, say dolphin and dog.

A Student: (in all earnestness) How do you differentiate between a dolphin and a dog?
A Voice from Back: Flippers, dude…

Funnel Laws of Discussion

Sungshin’s Funnel Law of Discussion:
When 2 or more guys start discussion, they start discussing a lot of topics. But, after a while the number of discussion topics goes on decreasing, till the time the only topic being discussed is Girls.

Fleiger’s Inverse Funnel law: (After a lot of research)
Girls start with only one topic: Shopping. But then the topics go on increasing till the time the number of topics is infinite.

An ode to Fick's Law

Got the grades from Electrobio mid-term on monday.

31 out of 37 students got a problem wrong. So we will get points for that if we submit it by today. Submitted the answer, got it correct [+5 marks :)]

5/37 got a question on Fick's law wrong. So, anybody who submits a haiku on Fick's law gets extra points. Wasn't expecting a lot of response to this offer, but what do I know... Prof got 7 haikus (if that is correct plural).

The best of them in my opinion is one by Robert (a grad student, of course.) So without further ado, as I have a lot to do, here's the winning entry (IMO):

Ode to Fick's 1st Law of Diffusion
by Rob Kirkton

Diffusivity ~
the particle migration
down concentration

Looks like engineers are getting poetic... And forgetting basic physics.

Location: BME 233 (Imaging) classroom

The prof asks somebody about Newton's second law. And in class full of BME undergrads, grads and Med-Physics people, not a single person can tell it. Shame on us... Looks like this theory is correct.

Yess... we got action potential

So finally, we had the much touted "frog lab" this week. Our anticipation was pretty much high following the "in old days" stories by our professor. (In old days, you had to come up with your own frogs... The first frog doesn't know, but by the 5th frog they are wondering, "Hey, where IS Johny???" and they know something is wrong etc. etc.)

So we all crowded around the Frog Master (sounded like Beast Master to me, but on the wrong side of line), and watched him putting a frog painlessly to death. And I could watch it; guess I could have stood med school after all (Sorry Nilesh). As each frog has 2 (rear) legs, we had a lot of frog legs to go around, and we Grad students became actual doers instead of watchers on the undergrads.

So Jason gets one frog leg, and me, Chris and Amorn try our luck with the other one. Dissecting a frog leg was not something I was thinking of doing; I am not a wannabe medical doctor after all. But still, we plowed on. At the end Jason comes up with the sciatic nerve removed surgically from the leg. His leg, sorry the one he dissected could still be cooked and served (frog leg is supposed to be a delicacy). But when we finally got the nerve out, our frog leg looked like the frog had just lost an argument with a minefield, a classic case of "too many hands spoil the dissection".

We had played around so much with the nerve, that we were not expecting to see anything when the nerve was connected. Jason gets a perfect action potential, after fiddling around the controls for maybe 10-15 min. After that, we connect the nerve we got out, and give it a stimulating pulse, and yesss...

We Got an Action Potential!!!!!

Jason: My bump is bigger that yours…
Amorn: It's not the size that matters, you know...

Back to Java!!

For all those people wondering what Java (as in software, not as in the life-fluid of all grads) has to do with Biomedical Engineering, I got a new job to develop a GUI (I used to hate these) in Java for one of the profs.
So it's back to Java and Eclipse for me! I didn't know how much I missed Eclipse till I sat down in front of my PC (details below) and started using it.
So Now I am going to work 15 hours a week on a Apple machine, with specs:


20" widescreen,
2.7GHz,
8 GB RAM (that's not a typo, you demons of envy)
And there is a new addition: a webcam


Now I come to think of it, some people used to envy me for a machine with 1GB RAM... (tsk tsk tsk)

And come 15th Dec, I will be moving to a new office (again not a typo), while other grads are languishing in their tiny cubicles. Like my prof said, I need to watch my back…

Time: 29th Oct, 2005, 11:00 am
Venue: Radiology Lab

My prof wants to use my machine for some work. I have some work till 12, so I tell him that I will be back after some time, and continue the work. At 12, the machine is still busy. So I go off and have some coffee. Back @ 1:40, still the machine is busy. At this moment, he turns to me, and says, "It's a nice afternoon, why don't you take the day off?" I don't mind if my weekend starts on Friday afternoon...


And whole next week, he is away in some part of Europe. :D

Post Test

Again a homework and a mid-term this week.

The midterms are over (finally)... The papers were good (as all Question papers are, its the answers... you got the idea). For Electrobiology, we had to write our own question and answer it, worth 18 marks. And before any of you say it's good, please imagine yourself sitting in the exam hall trying to frams a question, let alone answer to it. For imaging test, we had to give the "story" (in our prof's words) behind 8 equations. (Chris, if you are reading this, your flash-cards helped a lot. Thanks man!) All in all, an entirely different experience from the one we are used to...

These two weeks were extremely draining (emotionally and hence, physically) for various reasons, and this coupled with the good news that I got full marks in last week's Stat homework helped me decide to take 2 days off from studies. These two days will be dedicated to comparitive study of detective fiction, with special emphasis on Byomkesh Bakshi, thanks to this discussion and an extermely lucky co-incidence of finding two Byomkesh books (in english) in Duke Library.

Update: The two days are almost over, tomorrow I start again working on the Statistics homework due next week. For the results of my study, keep watching my other blog.

A Short Breather

Finished Fall Break last tuesday.

Schedule of this week:
Monday: Start a new job
Tuesday: Electrobio Test
Wednesday: Stat H/W
Thursday: Imaging H/W

Start studying for these: Last Friday.
Finished homework: 12.30 am today.

These were three of the most packed days of my life till now (yes, even including porsche)... Didn't call home, anybody.

Half way through this marathon, you get so stressed out that you are ready to walk in Kroger in your night suit, just to avoid the hassle of changing clothes when going out.

So finally, exams and homeworks are done, I have some breathing time to access the damage to my brain and get up-to-date on my blogs and communications. And I am already half way through the next Stats homework (due next tuesday), and wondering what is the latest time for which I can dare to keep the start of study for Imaging exam...

No wonder these professors using automatic transmission forget that we have something called 1st and 2nd gear, and even any self-respecting vehicle will stop running if you put it in 4th gear from neutral.

Start of the Fall Break

Sitting in front of my (ok, the one I borrowed) laptop, looking at papers and articles. The deadline of submission for the project proposal is 5 p.m. And it's seven PM already (Fall Break starts at 7).

The day started quite well.

Location: BME 201 (Electrobiology) Lab Quiz
Cast: Our lab group consisting of 6 people

The graduate students take "Group" quizzes. So we can freely discuss the problems (with kind consent of out professor), as long as we value the honour code (i.e. not look into our notes). Today, we had one problem in the lab quiz (the actual data is different for different people). After discussing for 15 solid minutes, we come up with the (wrong) formula. 3 people out of 6 somehow mess up the calculations, and get the right answers. And guess what...
I am one of those to get the wrong answer. Looks like my "famous" luck started the fall break a bit early.


The fall break has just started... Four days of relaxing, fun and enjoyment.

Tasks for Fall Break
1. Complete project proposal
2. Send replies to all e-mails I got in last week (last count was 10)
3. Call up home
4. Call people in US
5. Study
6. Cook for myself
7. Anything I have forgotten to put here

So looks like I have a period of great fun on my hands...

Guruwani

Attending college after 2 years is not easy. Attending classes, and that too for 75 minutes each, was one of the things which I would have never thought possible. (Because, as one of our professors reminded us the other day, a normal person’s attention span is around the length of situation comedy on TV.) But then, our classes taught by professors who don’t rely on unintentional humor to make the classes interesting.

So, we have got Statistics professor (who incidentally looks and acts like Robin Williams with beard) who teaches us about ecology experiments in Duke Forest, craps, and little apple seedlings. Then there is Electrobiology professor who gives us “Tips to win Nobel Prize”. Not to forget the Medical Imaging professor who told us in first lecture, “For last 50 years, we have done all the easy work in imaging, and kept all the hard work for you guys”.

So, unless you had a night-out on previous night, you can enjoy lectures a lot even without sleeping.

Some of the best quotes I have heard in class:

• "We have something called library where there are a lot of books to read. The only problem with library is, you get lost in it. You look in some racks, find some old magazines, start reading them and before you know, you are out of time."

• "There is a wonderful thing called Google. I had thought of it, but some guys from Stanford stole my idea. But then, I should say that they did a pretty good job of it."

• "The target in medical imaging devices is the Patient. That's the most important thing to remember."

• "This (some statistics fact) fact is so amazing that it should be in Ripley's Believe It or Not."

• "Mean is represented by Mju. Mean, mju... there is alliteration here, get it? For some reason we don't alliterate variance... variance, sigma square..."

• “Let’s do the first simulation first, and the second one… second”

• “Biomass is biological abbreviation of mass.”

• “Have you got your cadaver?”

• “Today, we are talking about frying your patient.”

• “The little seedlings come out of the ground. Then winter comes, and some of them die. It’s really a tragic story.”

Probability and Murphy's Laws

Sample Space:
Students from medical imaging class

Event:
Professor calling the random names picked from a glass, and asks the student questions. (He does not know your name if you haven't been called earlier.)

Observations:
1. The probability of getting called given that your mental state tends to "sleepy" is equal to 1.
2. The probability of getting called given that you are wide awake is equal to 0.

Conclusions:
Murphy's laws rule the earth!!!

My dear Watson....

Class: Medical Imaging
Scene: The professor has displayed X-Ray of a human hand, and asks a student ([un]fortunately an engineer) what can she see in that hand.

She goes on to describe that it is human hand. Then she tells that she can see some lesions etc etc. We all have a very shrewd idea that the prof is waiting for her to say something very important. After her monologue goes on for about 10 sentences, the professor asks, "OK, and do you see anything else?" We all hold our breaths... She doesn't have anything more to say.

Prof: OK, you have covered almost everything except one small thing... the person has his thumb missing.

Love theatre has never known a louder laughter in any class.

Does this remind you of Sherlock Holmes' camping trip?
