Question: What element did Carlo Perrier and Emilio Segre discover together?
Context: Livermorium is a synthetic superheavy element with symbol Lv and atomic number 116.  It is an extremely radioactive element that has only been created in the laboratory and has not been observed in nature.  The element is named after the Lawrence Livermore National Laboratory in the United States, which collaborated with the Joint Institute for Nuclear Research in Dubna, Russia to discover livermorium in 2000.  The name of the laboratory refers to the city of Livermore, California where it is located, which in turn was named after the rancher and landowner Robert Livermore.  The name was adopted by IUPAC on May 30, 2012.  Four isotopes of livermorium are known, with mass numbers between 290 and 293 inclusive; the longest-lived among them is livermorium-293 with a half-life of about 60 milliseconds.  A fifth isotope with mass number 294 has been reported but not yet confirmed. The Alcalá de Guadaira school was the name given to the circle of painters, initially brought together by Manuel Ussel de Guimbarda, who from 1890, centered on the figure of Emilio Sanchez Perrier, assembled and painted en plein air on the banks of the river Guadaíra, near Seville. "A Whole New World" is a song from Disney's 1992 animated feature film "Aladdin", with music by Alan Menken and lyrics by Tim Rice.  The song is a ballad between the primary characters Aladdin and Jasmine about the new world they are going to discover together while riding on Aladdin's magic carpet.  The original version was sung by Brad Kane and Lea Salonga during the film.  They also performed the song in their characters at the 65th Academy Awards, where it won Academy Award for Best Original Song as well as the first and so far only Disney song to win a Grammy Award for Song of the Year at the 36th Annual Grammy Awards.  In 2014, Adam Jacobs and Courtney Reed performed the song as Aladdin and Jasmine in the film's Broadway adaptation. Emilio Sánchez Perrier (1855 – 1907) was a Spanish landscape painter and watercolorist who also painted Orientalist subjects. A distributed element filter is an electronic filter in which capacitance, inductance and resistance (the elements of the circuit) are not localised in discrete capacitors, inductors and resistors as they are in conventional filters.  Its purpose is to allow a range of signal frequencies to pass, but to block others.  Conventional filters are constructed from inductors and capacitors, and the circuits so built are described by the lumped element model, which considers each element to be "lumped together" at one place.  That model is conceptually simple, but it becomes increasingly unreliable as the frequency of the signal increases, or equivalently as the wavelength decreases.  The distributed element model applies at all frequencies, and is used in transmission line theory; many distributed element components are made of short lengths of transmission line.  In the distributed view of circuits, the elements are distributed along the length of conductors and are inextricably mixed together.  The filter design is usually concerned only with inductance and capacitance, but because of this mixing of elements they cannot be treated as separate "lumped" capacitors and inductors.  There is no precise frequency above which distributed element filters must be used but they are especially associated with the microwave band (wavelength less than one metre). Carlo Perrier (7 July 1886 – 22 May 1948) was an Italian mineralogist who did extensive research on the element technetium in 1936.  He discovered the element along with his colleague, Emilio Segrè (1905-1989), in 1937. Emilio Gino Segrè (1 February 1905 – 22 April 1989) was an Italian physicist and Nobel laureate who discovered the elements technetium and astatine, and the antiproton, a sub-atomic antiparticle, for which he was awarded the Nobel Prize in Physics in 1959. Emilio Luigi Carlo Giuseppe Maria Ghione (July 30, 1879 – January 7, 1930), known as Emilio Ghione, was an Italian silent film actor, director and screenwriter.  Ghione was best known for writing, directing and starring in the Za La Mort series of adventure films, in which Ghione played a likeable French Apache and 'honest outlaw.'  Ghione directed, wrote and acted in every genre of film, and directed some of the most famous stars of the time, including Francesca Bertini, Lina Cavalieri, Alberto Collo and Hesperia.  After his final film role in 1926, Ghione briefly performed on a theatrical tour of Italy.  Ghione wrote three novels based around his Za La Mort character, an autobiography, and an essay on Italian Silent Cinema, before his death from tuberculosis in 1930. Carlo Emilio Bonferroni (28 January 1892 – 18 August 1960) was an Italian mathematician who worked on probability theory.  Carlo Emilio Bonferroni was born in Bergamo on 28 January 1892 and died on 18 August 1960 in Florence.  He studied in Turin, held a post as assistant professor at the Turin Polytechnic, and in 1923 took up the chair of financial mathematics at the Economics Institute in Bari.  In 1933 he transferred to Florence where he held his chair until his death. Emilio Baglioni became culinary host to the Hollywood stars, employed by Jack L. Warner of Warner Brothers Studios as the head of the commissary and executive dining room for Jack L. Warner and heads of every department and provided food for the actors and the crew during filming.  When Warner retired from the studio in 1968, Baglioni remained at Warner Brothers and opened his own restaurant at the same time simply called “Emilio’s” located on Melrose and Highland Avenues in Hollywood, California.  Many Hollywood stars continued to flock to Emilio’s because he prepared their favorite meals, such as Elizabeth Taylor’s beloved dinner was “Three colored salad;” Richard Burton Linguine with Clams; Esther Williams dined on “Veal Piccata;” Anthony Quinn liked "Scalappine al Marsala," Jack LaLane's "Cioppino;" John Wayne "Mixed Salad with New York Steak well charred;" Ava Gardner "Scampi al vino bianco.  The "Hollywood Times" newspaper reported: "Emilio's is currently & has been for many years the "In Place" to go in Hollywood.  Today you may see TV Newscaster, stars from nearby Paramount Studios, affluent people from everywhere gathered together to enjoy the beautiful atmosphere & outstand cuisine.  ...At Emilio's almost everything is prepared on the premises.  Breads are homebaked, fresh pastas are prepared daily & there is even a garden across from the restaurant where Emilio himself arrives early each morning to select his own vegetables, herbs, & beautiful flowers to set his tables...A legendary restaurant pioneer in Los Angeles, Emilio attributes his success to these words: "Never sacrifice quality & love your customers."  In 1995, Baglioni sold his restaurant, learned to play the Button Accordion and travels around the world entertaining people with Italian music, and makes special appearances at the Feast of San Gennaro Festivals in Los Angeles, California, and Las Vegas, Nevada.
