Drawing Monsters with Emil Ferris and Lynda Barry: An Exploration of the Drawing Process as Part of Graphic Medicine
This essay explores the role of drawing as a mode of processing intersectional violence, a strategy that I argue links Emil Ferrisâs comic, My Favorite Thing is Monsters (2018) to Lynda Barryâs pedagogical graphic narratives What It Is (2008) and Making Comics (2019). I argue that My Favorite Thing is Monsters embodies an enhanced version of graphic medicine that shifts the scale of analysis from the individual to the collective, revealing the health impact of intersectional oppressions. In its titular preoccupation with monsters, especially the Medusa, and its materialization of the protagonistâs sketch book, I further argue that Ferrisâs work of fiction recalls Barryâs exercise of drawing monsters. Continuing its exploration of the healing process of drawing, and drawing monsters, the essay concludes with an experiment in ethnographic criticism, reflecting on my own experience of drawing my way through the global pandemic of Covid-19 during the first six months of 2020
Baryon and antibaryon production in hadron-hadron and hadron-nucleus interactions
Cascade baryon and anti-baryon yields have been measured in p+p and p+A
collisions. After extraction of the projectile component in p+A interactions
close similarities with A+A collisions concerning the nuclear enhancement
factors are observed. In addition the importance of effects related to
projectile isospin and to net baryon stopping is pointed out.Comment: 4 pages, 5 figures, Presented at Quark Matter 2002, Nantes, Franc
EarthâMoonâMars Radiation Environment Module framework
[1] We are preparing to return humans to the Moon and setting the stage for exploration to Mars and beyond. However, it is unclear if long missions outside of low-Earth orbit can be accomplished with acceptable risk. The central objective of a new modeling project, the Earth-Moon-Mars Radiation Exposure Module (EMMREM), is to develop and validate a numerical module for characterizing time-dependent radiation exposure in the Earth-Moon-Mars and interplanetary space environments. EMMREM is being designed for broad use by researchers to predict radiation exposure by integrating over almost any incident particle distribution from interplanetary space. We detail here the overall structure of the EMMREM module and study the dose histories of the 2003 Halloween storm event and a June 2004 event. We show both the event histories measured at 1 AU and the evolution of these events at observer locations beyond 1 AU. The results are compared to observations at Ulysses. The model allows us to predict how the radiation environment evolves with radial distance from the Sun. The model comparison also suggests areas in which our understanding of the physics of particle propagation and energization needs to be improved to better forecast the radiation environment. Thus, we introduce the suite of EMMREM tools, which will be used to improve risk assessment models so that future human exploration missions can be adequately planned for
Coherent anti-Stokes Raman scattering microscopy for quantitative characterization of mixing and flow in microfluidics
We present an optical, noninvasive and label-free approach to characterize flow profiles in microfluidic devices. Coherent anti-Stokes Raman scattering signals were used to map the mass transport in a microfluidic device that was then related back to the local flow rate of dilute solutes having constant fluid properties. Flow characterization was demonstrated in two common types of microfluidic devices, polydimethylsiloxane/glass square channels and wet-etched glass tapered channels
A convenient category of locally preordered spaces
As a practical foundation for a homotopy theory of abstract spacetime, we
extend a category of certain compact partially ordered spaces to a convenient
category of locally preordered spaces. In particular, we show that our new
category is Cartesian closed and that the forgetful functor to the category of
compactly generated spaces creates all limits and colimits.Comment: 26 pages, 0 figures, partially presented at GETCO 2005; changes:

Q-Value for the Fermi Beta-Decay of 46V
By comparing the Q-values for the 46Ti(3He,t)46V and 47Ti(3He,t)47}V
reactions to the isobaric analog states the Q-value for the superallowed
Fermi-decay of 46V has been determined as Q_{EC}(46V)=(7052.11+/-0.27) keV. The
result is compatible with the values from two recent direct mass measurements
but is at variance with the previously most precise reaction Q-value. As
additional input quantity we have determined the neutron separation energy
S_n(47Ti)=(8880.51+/-0.25) keV
Signal averaging xâray streak camera with picosecond jitter
We have developed an averaging picosecond xâray streak camera using a dcâbiased photoconductive switch as a generator of a highâvoltage ramp. The streak camera is operated at a sweep speed of up to 8 ps/mm, shotâtoâshot jitter is less than ±1 ps. The streak camera has been used to measure the time history of broadband xâray emission from an ultrashort pulse laserâproduced plasma. Accumulation of the streaked xâray signals significantly improved the signalâtoânoise ratio of the data obtained. © 1996 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/69581/2/RSINAK-67-3-697-1.pd
