Question: What do E. B. White and Dan Masterson have in common?

Context paragraphs:
A-flat clarinet: The A-flat (A♭ ) clarinet is a member of the clarinet family, smaller and sounding a perfect fourth higher than the E♭ clarinet.  The A♭ is rare, but even less common, obsolete instruments in C, B♭ , and A♮ are listed by Shackleton.  Some writers call the A♭ and these other instruments octave clarinets, sopranino clarinets, or piccolo clarinets.  The boundary between the octave and soprano clarinets is not well-defined, and the rare instruments in G and F might be considered as either.  Shackleton, along with many early twentieth-century composers, uses the term "piccolo clarinet" to refer to the E♭ and D clarinets as well (piccolo merely meaning "small" in Italian).  This designation is less common today, with the E♭ and D instruments more usually designated soprano clarinets.  The term "piccolo clarinet" is used by some recent music software (e.g., Finale) for the A♭ clarinet.

Barn spider: Araneus cavaticus, commonly known as the barn spider, is a common orb-weaver spider native to North America.  They are around three-quarters of an inch (20 mm) in length and are usually yellow and brown in color.  They often construct their webs in wooden human structures, hence their common name.  The species is notable for being the basis for the character Charlotte in the book "Charlotte's Web" by American writer E. B. White.

Solitarily Speaking of Theoretical Confinement: Solitarily Speaking Of Theoretical Confinement is the second solo album by progressive metal guitarist Ron Jarzombek, released in 2002.  Every song follows a loose concept of basing each song's composition (Which are named after common phrases used in language) on certain songwriting systems created by Jarzombek himself (E.g., "To B or Not to B" consisting of 2 themes; Only using the note B (To B), and using every note except for B (Not to B); "A Headache and a Sixty-Fourth" is written in 65/64 time).

Dan Masterson: Dan Masterson (born February 22, 1934) is an American poet born in Buffalo, New York, United States (US).  He became a poet after several jobs as an actor, narrator, disc jockey (DJ), lay missionary worker, advertising copywriter, and theatrical public relations director.

Joel White: Joel White (1930–1997), the son of author E. B. White and New Yorker Magazine editor Katharine Sergeant Angell White, was a U.S. naval architect known for his classic designs including the W-Class of boats.  Two W boats were posthumously built by Rockport Marine and Brooklin Boat Yard for Donald Tofias.  They were christened "White Wings" and "Wild Horses".  White's life and character were chronicled in the book "A Unit of Water, A Unit of Time" by Douglass Whynott and in "Joel White: Boatbuilder / designer / sailor" by Bill Mayher and Maynard Bray.  White died at the age of 66 in 1997 in Brooklin, Maine of lung cancer.  His widow, Allene White, lives in Brooklin.

E. B. White: Elwyn Brooks "E. B." White (July 11, 1899 – October 1, 1985) was an American writer.  He was a contributor to The New Yorker magazine and a co-author of the English language style guide "The Elements of Style", which is commonly known as "Strunk & White".  He also wrote books for children, including "Stuart Little" in 1945, "Charlotte's Web" in 1952, and "The Trumpet of the Swan" in 1970.  "Charlotte's Web" was voted the top children's novel in a 2012 survey of "School Library Journal" readers, an accomplishment repeated from earlier surveys.

Soprano clarinet: The term soprano clarinet is used occasionally to refer to those instruments from the clarinet family that occupy a higher position, both in pitch and in popularity than subsequent additions to the family such as the basset horns and bass clarinets.  The B♭ clarinet is by far the most common type of clarinet and indeed the unmodified word "clarinet" usually refers to this instrument.  However, due to a tendency for writers and historians to imitate the terms used to denote instruments in other instrumental 'family groups' the term soprano is sometimes used to apply not only to the B♭ clarinet but also to the clarinets in A and C, sounding respectively a semitone lower and a whole tone higher than the B♭ instrument, and even the low G clarinet—rare in Western music but popular in the folk music of Turkey—sounding a whole tone lower than the A.  While some writers reserve a separate category of sopranino clarinets for the E♭ and D clarinets, these are more usually regarded as soprano clarinets as well.  All have a written range from the E below middle C to about the C three octaves above middle C, with the sounding pitches determined by the particular instrument's transposition.

X-linked agammaglobulinemia: X-linked agammaglobulinemia (XLA) is a rare genetic disorder discovered in 1952 that affects the body's ability to fight infection.  As the form of agammaglobulinemia that is X-linked, it is much more common in males.  In people with XLA, the white blood cell formation process does not generate mature B cells, which manifests as a complete or near-complete lack of proteins called gamma globulins, including antibodies, in their bloodstream.  B cells are part of the immune system and normally manufacture antibodies (also called immunoglobulins), which defend the body from infections by sustaining a humoral immunity response.  Patients with untreated XLA are prone to develop serious and even fatal infections.  A mutation occurs at the Bruton's tyrosine kinase (Btk) gene that leads to a severe block in B cell development (at the pre-B cell to immature B cell stage) and a reduced immunoglobulin production in the serum.  Btk is particularly responsible for mediating B cell development and maturation through a signaling effect on the B cell receptor BCR.  Patients typically present in early childhood with recurrent infections, in particular with extracellular, encapsulated bacteria.  XLA is deemed to have a relatively low incidence of disease, with an occurrence rate of approximately 1 in 200,000 live births and a frequency of about 1 in 100,000 male newborns.  It has no ethnic predisposition.  XLA is treated by infusion of human antibody.  Treatment with pooled gamma globulin cannot restore a functional population of B cells, but it is sufficient to reduce the severity and number of infections due to the passive immunity granted by the exogenous antibodies.

Twinkie defense: "Twinkie defense" is a derisive label for an improbable legal defense.  It is not a recognized legal defense in jurisprudence, but a catchall term coined by reporters during their coverage of the trial of defendant Dan White for the murders of San Francisco city Supervisor Harvey Milk and Mayor George Moscone.  White's defense was that he suffered diminished capacity as a result of his depression.  His change in diet from healthful food to Twinkies and other sugary foods was said to be a symptom of depression.  Contrary to common belief, White's attorneys did not argue that the Twinkies were the cause of White's actions, but that their consumption was symptomatic of his underlying depression.  White was convicted of voluntary manslaughter.

Stanley Hart White: Stanley Hart White was a professor of Landscape Architecture at the University of Illinois from 1922 until 1959 and the inventor of the green wall.  White called his invention "Botanical Bricks" and developed prototypes in his backyard in Urbana, Illinois.  Stanley's brother E.B. White documents the invention in his 1937 letter to Katherine S. White: “I guess everyone has crazy brothers and sisters.  I know I have.  Stan, by the way, has taken out a patent on an invention of his called ‘Botanical Bricks,’ which are simply plant units capable of being built up to any height, for quick landscape effects, the vertical surfaces covered with flowering vines, or the like.  He thinks that the idea has great possibilities for such things as world fairs, city yards, indoor gardens, and many other projects.  I think perhaps he has got hold of something, and have written him for more information.  He certainly deserves a break.”  Stanley refined the vertical garden typology with his patent for the "vegetation-Bearing Architectonic Structure and System (1938)" in which he outlines the scope for a new field of vegetation-bearing architecture.  The impact of this invention has still unrealized provocations on this history of gardens and designed landscapes, establishing precedent for verdant modernism in the prewar Middle West.  The wall was reconstructed in 2012-13 as part of a Graham Foundation Research Award.  Stanley Hart White is also known for his innovative teaching style and his influence on the work of Richard Haag, Hideo Sasaki, Peter Walker, Stu Dawson, Philip H. Lewis Jr., and numerous others Stanley Hart White married Blanche Bigney; they had one daughter, Janice Hart White, an accomplished artist.  As E. B. White's niece, Janice was an inspiration for the title character in Stuart Little, Harper and Brothers, 1945.
