Collecting, Documenting, and Sharing Detroit Arts Culture: In and Around Wayne State, 1960s-1980s
In the 1960s, as explosive social and political movements gave rise to the rejection of post-World War II middle-class society, Wayne State University and its nearby environs emerged as a cultural force. A loosely drawn community of artists, poets, musicians and politicos became active participants in this boldly expressive movement, with much activity centered in the Cass Corridor, adjacent to campus. While this mirrored what was going on in other parts of the country, Detroiters had their own source material, inspiration, and tools for expression.
This panel will present and discuss this important time in Detroit\u27s cultural history, and a number of projects undertaken to preserve its heritage. Featured will be a video which includes the work of a number of Cass Corridor artists from that time period, and two collaborative oral history projects which document the stories of Detroit\u27s art, poetry, and music communities.
The panel will be of interest to artists, art educators, art historians and those interested in Detroit arts history, as well as documentary practices.

Lightweight two-stroke cycle aircraft diesel engine technology enablement program, volume 1
An experimental Single Cylinder Test Engine Program is conducted to confirm the analytically projected performance of a two-stroke cycle diesel engine for aircraft applications. The test engine delivered 78kW indicated power from 1007cc displacement, operating at 3500 RPM on Schnuerle loop scavenged two-stroke cycle. Testing confirms the ability of a proposed 4-cylinder version of such an engine to reach the target power at altitude, in a highly turbocharged configuration. The experimental program defines all necessary parameters to permit design of a multicylinder engine for eventual flight applications; including injection system requirement, turbocharging, heat rejection, breathing, scavenging, and structural requirements. The multicylinder engine concept is configured to operate with an augmented turbocharger, but with no primary scavenge blower. The test program is oriented to provide a balanced turbocharger compressor to turbine power balance without an auxiliary scavenging system. Engine cylinder heat rejection to the ambient air has been significantly reduced and the minimum overall turbocharger efficiency required is within the range of commercially available turbochargers. Analytical studies and finite element modeling is made of insulated configurations of the engines - including both ceramic and metallic versions. A second generation test engine is designed based on current test results

Quantitative copper measurement in oxidized p-type silicon wafers using microwave photoconductivity decay
We propose a method to measure trace copper contamination in p-type silicon using the microwave photoconductivity decay (ÎŒ-PCD) technique. The method is based on the precipitation of interstitial copper, activated by high-intensity light, which results in enhanced minority carrier recombination activity. We show that there is a quantitative correlation between the enhanced recombination rate and the Cu concentration by comparing ÎŒ-PCD measurements with transient ion drift and total reflection x-ray fluorescence measurements. The results indicate that the method is capable of measuring Cu concentrations down to 10exp10cmâ3. There are no limitations to wafer storage time if corona charge is used on the oxidized wafer surfaces as the charge prevents copper outdiffusion. We briefly discuss the role of oxide precipitates both in the copperprecipitation and in the charge carrier recombination processes.Peer reviewe
Kinetic Energy Release Distributions for Câșâ Emission from Multiply Charged Cââ and Cââ Fullerenes
We present asystematic study of experimental kinetic energy release distributions for the asymmetric fission processes Cq+60 C(iq-1\u3c)+70+ C+2 and C q+70 C(q-1)+60+ C+ 2 for mother ions incharge states q 4-8 produced incollisions with slow highly charged ions. Somewhat to our surprise, we find that the KERD for asymmetric fission from Cq+60 are considerably wider and have larger most likely values than the Cq+70 distributions inthe corresponding charge states when q \u3e 4
Projected SO(5) Hamiltonian for Cuprates and Its Applications
The projected SO(5) (pSO(5)) Hamiltonian incorporates the quantum spin and
superconducting fluctuations of underdoped cuprates in terms of four bosons
moving on a coarse grained lattice. A simple mean field approximation can
explain some key feautures of the experimental phase diagram: (i) The Mott
transition between antiferromagnet and superconductor, (ii) The increase of T_c
and superfluid stiffness with hole concentration x and (iii) The increase of
antiferromagnetic resonance energy as sqrt{x-x_c} in the superconducting phase.
We apply this theory to explain the ``two gaps'' problem found in underdoped
cuprate Superconductor-Normal- Superconductor junctions. In particular we
explain the sharp subgap Andreev peaks of the differential resistance, as
signatures of the antiferromagnetic resonance (the magnon mass gap). A critical
test of this theory is proposed. The tunneling charge, as measured by shot
noise, should change by increments of Delta Q= 2e at the Andreev peaks, rather
than by Delta Q=e as in conventional superconductors.Comment: 3 EPS figure
Two-Center Interference in p-H2 Electron-Transfer Collisions
We report on measurements of transfer excitation in collisions of 0.3-1.3 MeV protons with spatially oriented H2 molecules. Evidences of two center interference are found in the angular distribution of the molecule after a transfer excitation process and directly in the projectile angular scattering distributions. These features can be explained in a way which is analogous to that for the interferences in Young\u27s classical double slit experiment: The fast projectiles preferentially capture electrons close to either of the molecular nuclei, and thereby they change their momenta and de Broglie wavelengths. The waves emerging from the two \u27slits\u27 of the molecule interfere yielding the observed interference structure
Evidence of Wave-Particle Duality for Single Fast Hydrogen Atoms
We report the direct observation of interference effects in a Young\u27s double-slit experiment where the interfering waves are two spatially separated components of the de Broglie wave of single 1.3 MeV hydrogen atoms formed close to either target nucleus in H++H2 electron-transfer collisions. Quantum interference strongly influences the results even though the hydrogen atoms have a de Broglie wavelength, λdB, as small as 25 fm

Inclusive J/Ï production at mid-rapidity in pp collisions at âs = 5.02 TeV
Inclusive J/Ï production is studied in minimum-bias proton-proton collisions at a centre-of-mass energy of s = 5.02 TeV by ALICE at the CERN LHC. The measurement is performed at mid-rapidity (|y| < 0.9) in the dielectron decay channel down to zero transverse momentum pT, using a data sample corresponding to an integrated luminosity of Lint = 19.4 ± 0.4 nbâ1. The measured pT-integrated inclusive J/Ï production cross sec- tion is dÏ/dy = 5.64 ± 0.22(stat.) ± 0.33(syst.) ± 0.12(lumi.) ÎŒb. The pT-differential cross section d2Ï/dpTdy is measured in the pT range 0â10 GeV/c and compared with state-of- the-art QCD calculations. The J/Ï ăpTă and ăpT2ă are extracted and compared with results obtained at other collision energies. [Figure not available: see fulltext.]

Measurement of Î (1520) production in pp collisions at âs=7TeV and pâPb collisions at âsNN=5.02TeV
The production of the Î (1520) baryonic resonance has been measured at midrapidity in inelastic pp collisions at s=7TeV and in pâPb collisions at sNN=5.02TeV for non-single diffractive events and in multiplicity classes. The resonance is reconstructed through its hadronic decay channel Î (1520) â pK - and the charge conjugate with the ALICE detector. The integrated yields and mean transverse momenta are calculated from the measured transverse momentum distributions in pp and pâPb collisions. The mean transverse momenta follow mass ordering as previously observed for other hyperons in the same collision systems. A Blast-Wave function constrained by other light hadrons (Ï, K, KS0, p, Î) describes the shape of the Î (1520) transverse momentum distribution up to 3.5GeV/c in pâPb collisions. In the framework of this model, this observation suggests that the Î (1520) resonance participates in the same collective radial flow as other light hadrons. The ratio of the yield of Î (1520) to the yield of the ground state particle Î remains constant as a function of charged-particle multiplicity, suggesting that there is no net effect of the hadronic phase in pâPb collisions on the Î (1520) yield
