Letter from Bishop R.R. Roberts to James B. Finley
Bishop Roberts has just finished presiding at the Illinois Conference and reports peace and harmony among the preachers. Bishop McKendree was there in good health and expects to go to the Kentucky Conference, as does Bishop Roberts. He regrets that he will not be able to attend the Ohio Conference because he wishes to see Finley. Roberts will not be able to pay Finley the money he owes him, but will send $75.00 with Brother M. Ruter to pass on to him. He tells Finley about the establishment of a school and mission among the Potawatomi Indians under the missionary leadership of Bro. Walker [Jesse]. Roberts sends his warm regards. Abstract Number - 609https://digitalcommons.owu.edu/finley-letters/1705/thumbnail.jp
Letter from Bishop R.R. Roberts to James B. Finley
Finley is serving as the Presiding Elder of the Ohio District (Ohio Conference), which includes the eastern Ohio circuits of Beaver, Erie, Grand River and Mahonan, Chatauque, Steubenville, Tuscarawas and Huron. Bishop Roberts lets Finley know that he will not be in attendance at the Ohio Conference in Steubenville. He believes that Bishop George and Bishop McKendree will be in attendance. Included in the letter are the 1818 appointments for the Baltimore Conference. Abstract Number - 605https://digitalcommons.owu.edu/finley-letters/1901/thumbnail.jp
Accurate and robust image superresolution by neural processing of local image representations
Image superresolution involves the processing of an image sequence to generate a still image with higher resolution. Classical approaches, such as bayesian MAP methods, require iterative minimization procedures, with high computational costs. Recently, the authors proposed a method to tackle this problem, based on the use of a hybrid MLP-PNN architecture. In this paper, we present a novel superresolution method, based on an evolution of this concept, to incorporate the use of local image models. A neural processing stage receives as input the value of model coefficients on local windows. The data dimension-ality is firstly reduced by application of PCA. An MLP, trained on synthetic se-quences with various amounts of noise, estimates the high-resolution image data. The effect of varying the dimension of the network input space is exam-ined, showing a complex, structured behavior. Quantitative results are presented showing the accuracy and robustness of the proposed method
Search for Exotic Mesons in pi- P Interactions at 18 GeV/c
The recent search for non mesons in interactions at
Brookhaven National Laboratory is summarized. Many final states such as , , , , , ,
which are favored decay modes of exotics, are under investigation.Comment: 9 pages, PostScript, Presented at the International School of Nuclear

VERTIGO (VERtical Transport In the Global Ocean) : a study of particle sources and flux attenuation in the North Pacific

The definitive version was published in Deep Sea Research Part II: Topical Studies in Oceanography 55 (2008): 1522-1539, doi:10.1016/j.dsr2.2008.04.024.The VERtical Transport In the Global Ocean (VERTIGO) study examined particle sources and
fluxes through the oceanâs âtwilight zoneâ (defined here as depths below the euphotic zone to
1000 m). Interdisciplinary process studies were conducted at contrasting sites off Hawaii
(ALOHA) and in the NW Pacific (K2) during 3 week occupations in 2004 and 2005, respectively.
We examine in this overview paper the contrasting physical, chemical and biological settings and
how these conditions impact the source characteristics of the sinking material and the transport
efficiency through the twilight zone. A major finding in VERTIGO is the considerably lower
transfer efficiency (Teff) of particulate organic carbon (POC), POC flux 500 / 150 m, at ALOHA
(20%) vs. K2 (50%). This efficiency is higher in the diatom-dominated setting at K2 where
silica-rich particles dominate the flux at the end of a diatom bloom, and where zooplankton and
their pellets are larger. At K2, the drawdown of macronutrients is used to assess export and
suggests that shallow remineralization above our 150 m trap is significant, especially for N
relative to Si. We explore here also surface export ratios (POC flux/primary production) and
possible reasons why this ratio is higher at K2, especially during the first trap deployment. When
we compare the 500 m fluxes to deep moored traps, both sites lose about half of the sinking POC
by >4000 m, but this comparison is limited in that fluxes at depth may have both a local and
distant component. Certainly, the greatest difference in particle flux attenuation is in the
mesopelagic, and we highlight other VERTIGO papers that provide a more detailed examination
of the particle sources, flux and processes that attenuate the flux of sinking particles. Ultimately,
we contend that at least three types of processes need to be considered: heterotrophic degradation
of sinking particles, zooplankton migration and surface feeding, and lateral sources of suspended
and sinking materials. We have evidence that all of these processes impacted the net attenuation
of particle flux vs. depth measured in VERTIGO and would therefore need to be considered and
quantified in order to understand the magnitude and efficiency of the oceanâs biological pump.Funding for VERTIGO was provided primarily by research grants

Observation of a New J(PC)=1(+-) Isoscalar State in the Reaction Pi- Proton -> Omega Eta Neutron at 18 GeV/c
Results are presented on a partial wave analysis of the Omega Eta final state
produced in Pi- Proton interactions at 18 GeVc where Omega -> Pi+ Pi- Pi0, Pi0
-> 2 Gammas, and Eta -> 2 Gammas. We observe the previously unreported decay
mode Omega(1650) -> Omega Eta and a new 1(+-) meson state h1(1595) with a mass
M=1594(15)(+10)(-60) MeV/c^2 and a width Gamma=384(60)(+70)(-100) MeV/c^2. The
h1(1595) state exhibits resonant-like phase motion relative to the Omega(1650).Comment: Submitted to Physics Letters B Eight total pages including 11 figures

Partial-wave analysis of the eta pi+ pi- system produced in the reaction pi-p --> eta pi+ pi- n at 18 GeV/c
A partial-wave analysis of 9082 eta pi+ pi- n events produced in the reaction
pi- p --> eta pi+ pi- n at 18.3 GeV/c has been carried out using data from
experiment 852 at Brookhaven National Laboratory. The data are dominated by
J^{PC} = 0^{-+} partial waves consistent with observation of the eta(1295) and
the eta(1440). The mass and width of the eta(1295) were determined to be 1282
+- 5 MeV and 66 +- 13 Mev respectively while the eta(1440) was observed with a
mass of 1404 +- 6 MeV and width of 80 +- 21 MeV. Other partial waves of
importance include the 1++ and the 1+- waves. Results of the partial wave
analysis are combined with results of other experiments to estimate f1(1285)
branching fractions. These values are considerably different from current
values determined without the aid of amplitude analyses.Comment: 22 pages, 8 figure
