A Method of Collecting Catocala Minuta (Lepidoptera: Noctuidae) and Related Species

Excerpt: During the last twelve years I have \u27sugared\u27 extensively in areas where large honey locusts (Gleditsia triacanthos L.) are abundant. Although the various forms of Catocala innubens Guenee and Stvenoloma lunilinea (Grote) have appeared in my bait traps, Catocah rninuta Edwards has been absent. [C. minuta is taken on Gleditsia in southern Michigan by using a mixture of molasses, brown sugar, beer and,rum-- Ed.] There is, however, amethodof collecting the pupae of C. minuta that I have employed with excellent results

How to Defeat W\"{u}thrich’s Abysmal Embarrassment Argument against Space-Time Structuralism

In his 2009 PSA Recent Ph.D. Award winning contribution to the bi-annual PSA Conference at Pittsburgh in 2008, C. Wu ̈thrich mounted an argument against struc- turalism about space-time in the context of the General Theory of Relativity (GTR), to the effect that structuralists cannot discern space-time points. An “abysmal embarrass- ment” for the structuralist, Wu ̈thrich judged. Wu ̈thrich’s characterisation of space-time structuralism is however incorrect. We demonstrate how, on the basis of a correct char- acterisation of space-time structuralism, it is possible to discern space-time points in the GTR-structures under consideration. Thus Wu ̈thrich’s argument crumbles

Recent Tests of QCD at SLD

We present selected results on strong interaction physics from the SLD experiment at the SLAC Linear Collider. We report on several new studies of 3- and 4-jet hadronic Z decays, in which jets are identified as quark, antiquark or gluon. The 3-jet Z^0->b\bar{b}g rate is sensitive to the b-quark mass; prospects for measuring m_b are discussed. The gluon energy spectrum is measured over the full kinematic range, providing an improved test of QCD and limits on anomalous bbg couplings. The parity violation in Z^0->b\bar{b}g decays is consistent with electroweak theory plus QCD. New tests of T- and CP-conservation at the bbg vertex are performed. A new measurement of the rate of gluon splitting into b\bar{b} pairs yields g_{b\bar{b}}=0.0031+-0.0007(stat.)+-0.0006(syst.) (Preliminary). We also present a number of new results on jet fragmentation into identified hadrons. The B hadron energy spectrum is measured over the full kinematic range using a new, inclusive technique, allowing stringent tests of predictions for its shape and a precise measurement of =0.714+-0.005(stat.)+-0.007(syst.) (Preliminary). A detailed study of correlations in rapidity y between pairs of identified pions, kaons and protons confirms that strangeness and baryon number are conserved locally, and shows local charge conservation between meson-baryon and strange-nonstrange pairs. Flavor-dependent long-range correlations are observed for all combinations of these hadron species, yielding new information on leading particle production. The first study of correlations using rapidities signed such that y>0 corresponds to the quark direction provides additional new insights into fragmentation, including the first direct observation of baryon number ordering along the q\bar{q} axis.Comment: 20 pages, 12 figs.; talk given at the QCD99 meeting, Montpellier, France, 7-13 July, 1999; a smaller-print version will appear in the proceeding

Hadron Physics at BABAR

The BaBar experiment at SLAC is designed to measure CP violation in the B meson system, however the very high statistics combined with the different electron and positron beam energies, the detector design and the open trigger allow a wide variety of spectroscopic measurements. We are beginning to tap this potential via several production mechanisms. Here we present recent results from initial state radiation, hadronic jets, few body B and D hadron decays, and interactions in the detector material. We also summarize measurements relevant to Ds meson spectroscopy, pentaquarks and charmonium spectroscopy from multiple production mechanisms.Comment: 10 pages, 7 eps figures, contributed to the Proceedings of HADRON0
