input: On September 16, 1952, Pauling opened a new research notebook with the words "I have decided to attack the problem of the structure of nuclei." On October 15, 1965, Pauling published his Close-Packed Spheron Model of the atomic nucleus in two well respected journals, Science and the Proceedings of the National Academy of Sciences. For nearly three decades, until his death in 1994, Pauling published numerous papers on his spheron cluster model.  The basic idea behind Pauling's spheron model is that a nucleus can be viewed as a set of "clusters of nucleons". The basic nucleon clusters include the deuteron [np], helion [pnp], and triton [npn]. Even-even nuclei are described as being composed of clusters of alpha particles, as has often been done for light nuclei. Pauling attempted to derive the shell structure of nuclei from pure geometrical considerations related to Platonic solids rather than starting from an independent particle model as in the usual shell model. In an interview given in 1990 Pauling commented on his model:  Now recently, I have been trying to determine detailed structures of atomic nuclei by analyzing the ground state and excited state vibrational bends, as observed experimentally. From reading the physics literature, Physical Review Letters and other journals, I know that many physicists are interested in atomic nuclei, but none of them, so far as I have been able to discover, has been attacking the problem in the same way that I attack it. So I just move along at my own speed, making calculations...

Answer this question "What else can you tell me about his model?"
output: basic nucleon clusters include the deuteron [np], helion [pnp], and triton [npn].

Problem: Background: George Jacob Gershwin (; September 26, 1898 -  July 11, 1937) was an American composer and pianist. Gershwin's compositions spanned both popular and classical genres, and his most popular melodies are widely known. Among his best-known works are the orchestral compositions Rhapsody in Blue (1924) and An American in Paris (1928), as well as the contemporary opera Porgy and Bess (1935).
Context: On September 26, 1898, George was born as second son to Morris and Rose Bruskin Gershwine in their second-floor apartment on Brooklyn's Snediker Avenue. His birth certificate identifies him as Jacob Gershwine, with the surname pronounced 'Gersh-vin' in the Russian and Yiddish immigrant community. He had just one given name, contrary to the American practice of giving children both a first and middle name. He was named after his grandfather, a one time Russian army mechanic. He soon became known as George, and changed the spelling of his surname to 'Gershwin' about the time he became a professional musician; other family members followed suit. After Ira and George, another boy Arthur Gershwin (1900-1981), and a girl Frances Gershwin (1906-1999) were born into the family.  The family lived in many different residences, as their father changed dwellings with each new enterprise in which he became involved. Mostly, they grew up around the Yiddish Theater District. George and Ira frequented the local Yiddish theaters, with George occasionally appearing onstage as an extra.  George lived a usual childhood existence for children of New York tenements: running around with his boyhood friends, roller skating and misbehaving in the streets. Remarkably, until 1908, he cared nothing for music, when as a ten year old he was intrigued upon hearing his friend Maxie Rosenzweig's, violin recital. The sound, and the way his friend played, captured him. At around the same time, George's parents had bought a piano, for lessons, for his older brother Ira, but to his parents' surprise, and Ira's relief, it was George who spent more time playing it.  Although his younger sister Frances was the first in the family to make a living through her musical talents, she married young and devoted herself to being a mother and housewife, thus surrendering any serious time to musical endeavors. Having given up her performing career, she settled upon painting as a creative outlet, which had also been a hobby George briefly pursued. Arthur Gershwin followed in the paths of George and Ira, also becoming a composer of songs, musicals, and short piano works.  With a degree of frustration, George tried various piano teachers for some two (circa. 1911) before finally being introduced to Charles Hambitzer by Jack Miller (circa. 1913), the pianist in the Beethoven Symphony Orchestra. Until his death in 1918, Hambitzer remained Gershwin's musical mentor and taught him conventional piano technique, introduced him to music of the European classical tradition, and encouraged him to attend orchestral concerts. Following such concerts, young Gershwin would essentially try to play, on the piano at home, the music he had heard from recall, and without sheet music. As a matter of course, Gershwin later studied with the classical composer Rubin Goldmark and avant-garde composer-theorist Henry Cowell, thus formalizing his classical music training.
Question: Was Ancestors a title of a song?
Answer: George was born as second son to Morris and Rose Bruskin Gershwine in their second-floor apartment

Question: Ann Margaret Veneman (born June 29, 1949) was the Executive Director of UNICEF from 2005 to 2010. Her appointment was announced on January 18, 2005 by UN Secretary-General Kofi Annan. Previously, Veneman was the United States Secretary of Agriculture, the first, and as of 2018 the only, woman to hold that position. Veneman served as USDA Secretary from January 20, 2001 to January 20, 2005, leaving to become the fifth executive director of UNICEF.

Veneman began her legal career as a staff attorney with the General Counsel's office of the Bay Area Rapid Transit District in Oakland, California, in 1976. In 1978, she returned to Modesto, where she served as a Deputy Public Defender. In 1980, she joined the Modesto law firm of Damrell, Damrell and Nelson, where she was an associate and later a partner.  Veneman joined the United States Department of Agriculture's Foreign Agricultural Service in 1986, serving as Associate Administrator until 1989. During this time she worked on the Uruguay Round talks for the General Agreement on Tariffs and Trade (GATT). She subsequently served as Deputy Undersecretary of Agriculture for International Affairs and Commodity Programs from 1989 to 1991. From 1991 to 1993, she served as United States Department of Agriculture's Deputy Secretary, the first woman appointed as the Department's second-highest-ranking official. At this point Veneman took a break from political and administrative office to practice with the law firm and lobby group Patton, Boggs & Blow and also served on several boards of directors and advisory groups.  In 1995 Veneman re-entered government, when she was appointed Secretary of the California Department of Food and Agriculture, again being the first woman to hold the position. From 1999 to 2001 Veneman was an attorney with Nossaman LLP, where she focused her attention on food, agriculture, environment, technology, and trade related issues. On 20 January 2001 she was unanimously confirmed by the United States Senate and sworn in as Secretary of Agriculture, a position she held until January 20, 2005.

Using a quote from the above article, answer the following question: is there anything else that she did during this time?
