The leptonic and inclusive hadronic decay branching fractions of the W boson are studied using 35.9 $fb^{-1}$ of proton-proton collision data collected at $\sqrt{s}=13~TeV$ during the 2016 run of the CMS experiment. Events characterized by the production of pairs of W bosons from \ttbar and \tW processes are selected. Multiple...
When a cell divides, it must assemble a microtubule-based structure called a spindle, which provides the forces that physically segregate the chromosomes. In most cell types the microtubules that comprise the spindle are nucleated and organized by centriole-containing centrosomes. In many species, however, oocyte meiosis is carried out in the...
This dissertation reports on a 16-week ethnographic study of politicized caring within a museum-based tinkering program for high school students called the FabYouth program. Drawing on a data set that includes 16 field notes, 785.83 minutes (about 13.1 hours) of ethnographic audio-video recordings, 280 photographs, and ten student interviews, I...
A great deal of work has been done in recent years to construct algebraic invariants ofLegendrian knots, and their higher-dimensional analogues. Here we employ the diagram-
matic calculus developed in [3], in order to develop an iterative method for computing the
so-called vexillary functions of a class of Legendrian surfaces....
Every music theorist has their own personal reasons for engaging in the craft of theorizing about music. Many discover that there is something special about a theoretic disposition which differs from other sorts of interactions with music. It is often this special something that draws musicians into the discipline: specifically,...

Exposure to violence, which includes child abuse, neglect, witnessing domestic or community violence, crime, and sexual assault, is a national concern. Over the course of a year, 68% of children under age 17 are exposed to at least one form of violence (Finkelhor, Turner, Shattuck, & Hamby, 2015). Young children...
The Escherichia coli ribosome is a molecular machine capable of sequence-defined polymerization of -amino acids into proteins, a feat unmatched by any other current synthetic catalyst. It is complex in its structure, comprised of 3 RNA parts (the 5S, 16S, and 23S ribosomal RNAs) and 54 ribosomal proteins (r-proteins). Efforts...
From the 1990s through the 2000s, gross-out comedy – in the broadest terms, the style of physical comedy that emphasizes bodily functions and fluids, transgressive imagery and behavior, and shock value and disgust – triumphed as a subgenre of popular narrative film and television comedy. Gross-out comedy first emerged as...
Political leaders often engage in open fights for recognition, announcing that some crucial element of their state’s identity, status, or history, has not been properly acknowledged and respected in the conduct of diplomacy. Among international relations scholars, these instances are usually ascribed to the fact that states, like individuals, need...
