- Abstract: Several special fighting forces from the United States, made up of single ethnic groups, made significant contributions during World War II, including the African American Tuskegee Airmen and the Navajo Code Talkers. The 442nd Regimental Combat Team was made up solely of Japanese Americans, some of whom were recruited directly from internment camps. (Some Japanese American men who would later become leaders, such as Senator Daniel Inouye, were members of the 442nd.) The images in this group provide a look at the lives and sacrifices of the men of the 442nd, the most highly decorated American unit in WWII. The photographs in this group were all taken for the government-run War Relocation Authority (WRA) and are meant to portray the proud patriotism of the men and their families. One photo shows three women holding their babies, with photographs of their enlisted husbands. Another is a portrait of an older couple who had five sons in the 442nd. Other photographs reflect the training the soldiers of the 442nd received, their life in the battlefield, and their triumphant homecoming. Other documents in this group show a more personal side of the men of the 442nd. One soldier's photo album depicts his personal experiences as a member of the combat team. A 50-page booklet, The Story of the 442nd Combat Team, compiled by members of the team, has this quote from Franklin D. Roosevelt on the dedication page: "Americanism is a matter of the mind and heart; Americanism is not and never was a matter of race and ancestry." On a more poignant note, oil paintings by Japanese American artist Henry Sugimoto reflect the emotions, pain, and suffering these individuals and their families experienced as a result of the war. In Senninbari (Thousand Stiches), a woman holds a scarf of remembrance as a ghostly Nisei soldier looks down from the sky. And in Send Off Husband at Jerome Camp, an internee family stays behind the camp gates as their soldier father/husband goes off to fight for the United States.

- Abstract: ABCD's of Melanoma.
Malignant Melanoma is the most aggressive of malignant cutaneous tumours. Cases with lymphonode involvement, and distant metastases, carry a very poor prognosis, (50% and 20% respectively alive in 5 years), while those presenting without evident lymphonode involvement have a much better survival rate (60% alive in 5 years).
It is therefore extremely important to do early malignant melanoma diagnosis. There are several criteria that may lead to the diagnosis of a malignant melanoma. The most important one is the ABCD rule.
The ABCD diagnosis of Malignant Melanoma -
A = Asymmetry: Moles are commonly symmetrical and round. Very early melanomas, are asymmetrical assuming different forms. One half does not match the other half.
B = Border: Commonly moles, have even and smooth borders. Early melanomas, are usually uneven and notched borders. The edges are ragged, notched or blurred.
C = Color: Moles commonly are a single shade of brown, early malignant melanomas shows brown-tan or black color. Further, as melanomas progress, may see red, white, and blue color.
D = Diameter: Early malignant melanomas, differently from moles, tend to grow larger in diameter. First suspects in melanoma start from a 6 millimeters diameter on. Any sudden or continuing increase in size should be of special concern.
Synthesis: a mole with diameter of 6 millimeter, that it introduces alterations - irregular asymmetry, edges, color - must induce the patient to address early on dermatologist to careful clinical and dermatoscopic examination and consequently, if necessary, to surgical removal of the lesion, with successive hystological examination.
Melanoma Prevention
According to the risk factors for malignant melanoma, the following preventive measures are also recommended:
* UV exposure, should be reduced. Prolonged sunbathing, as well as the use of tanning lamps, is not recommended. Children, under three years of age, should be held in the shade.
* Sun protection, should be obtained through suitable clothing. Children should be peculiarly dressed when playing outside.
* Use adequate sunscreens.
* Sunburns should be avoided, particularly in children.
Therefore people with multiple and abnormal moles, or with a family history of malignant melanoma, should have their skin checked continuously by a doctor/dermatologist.

- Abstract: The design of algorithms is studied, according to methodology and application. Methodologies include: divide and conquer, dynamic programming, and greedy strategies. Applications involve: sorting, ordering and searching, graph algorithms, geometric algorithms, mathematical (number theory, algebra and linear algebra) algorithms, and string matching algorithms. Analysis of algorithms is studied - worst case, average case, and amortized - with an emphasis on the close connection between the time complexity of an algorithm and the underlying data structures. NP-Completeness theory is examined along with methods of coping with intractability, such as approximation and probabilistic algorithms.

- Abstract: This class analyzes complex biological processes from the molecular, cellular, extracellular, and organ levels of hierarchy. Emphasis is placed on the basic biochemical and biophysical principles that govern these processes. Examples of processes to be studied include chemotaxis, the fixation of nitrogen into organic biological molecules, growth factor and hormone mediated signaling cascades, and signaling cascades leading to cell death in response to DNA damage. In each case, the availability of a resource, or the presence of a stimulus, results in some biochemical pathways being turned on while others are turned off. The course examines the dynamic aspects of these processes and details how biochemical mechanistic themes impinge on molecular/cellular/tissue/organ-level functions. Chemical and quantitative views of the interplay of multiple pathways as biological networks are emphasized. Student work will culminate in the preparation of a unique grant application in an area of biological networks.
