Dynamics of hadron strong production and decay

We generalize results of lattice QCD to determine the spin-dependent symmetries and factorization properties of meson production in OZI allowed processes. This explains some conjectures previously made in the literature about axial meson decays and gives predictions for exclusive decays of vector charmonia, including ways of establishing the structure of Y(4260) and Y(4325) from their S-wave decays. Factorization gives a selection rule which forbids $e^+e^- \to D^* D_2$ near threshold with the tensor meson in helicity 2. The relations among amplitudes for double charmonia production \e^+e^-\to \psi\chi_{0,1,2} are expected to differ from the analagous relations among light flavour production such as \e^+e^-\to \omega f_{0,1,2}.Comment: 13 pages; journal versio

A Non-Homogeneous, Spatio-temporal, Wavelet Multiresolution Analysis and Its Application to the Analysis of Motion

This research presents a multiresolution wavelet analysis tool for analyzing motion in time sequential imagery. A theoretical framework is developed for constructing an L2R wavelet multiresolution analysis from three non-identical spatial and temporal L2R wavelet multiresolution analyses. This framework provides the flexibility to tailor the spatio-temporal frequency characteristics of the three dimensional wavelet filter to match the frequency behavior of the analyzed signal. An unconventional, discrete multiresolution wavelet decomposition algorithm is developed which yields a rich set of independent spatio-temporally oriented frequency channels for analyzing, the size and speed characteristics of moving objects. Unlike conventional wavelet decomposition methods, this algorithm provides independent zoom-in and zoom-out capability in space and time. Symmetric 3D filters produced by the unconventional decomposition process are combined with the properties of the Hilbert transform to produce a bank of directionally selective wavelet filters. Multiple directionally selective wavelet filters are integrated to form a multiresolution vector wavelet motion sensor capable of unambiguously computing the optical flow of a 3D image sequence. A unique flow restoration methodology is presented which incorporates a modified version of Grossbergs gated dipole filter in a cooperative-competitive flow restoration methodology that reinforces consistent flow behavior and removes flow inconsistencies. Finally, several digital and optical parallel architectures arc investigated for their ability to speed up the 3D wavelet decomposition process

Pencil-Beam Surveys for Faint Trans-Neptunian Objects

We have conducted pencil-beam searches for outer solar system objects to a limiting magnitude of R ~ 26. Five new trans-neptunian objects were detected in these searches. Our combined data set provides an estimate of ~90 trans-neptunian objects per square degree brighter than ~ 25.9. This estimate is a factor of 3 above the expected number of objects based on an extrapolation of previous surveys with brighter limits, and appears consistent with the hypothesis of a single power-law luminosity function for the entire trans-neptunian region. Maximum likelihood fits to all self-consistent published surveys with published efficiency functions predicts a cumulative sky density Sigma(<R) obeying log10(Sigma) = 0.76(R-23.4) objects per square degree brighter than a given magnitude R.Comment: Accepted by AJ, 18 pages, including 6 figure

Elective Affinities in the Anthropocene: Christianity and the Natural Environment Reconsidered

To reach a deeper understanding of the complex relationship between religion and the natural environment, it is important to move beyond essentializing any religious tradition as having a pro-environmental or anti-environmental ethic. Rather, prior work has shown that the canonical, scholarly, and popular literatures and discourse of a number of religious traditions can and have been socially and rhetorically constructed as supporting an array of positions, from preservation to profligacy, and much in between those two ideal types. In this paper, we develop Max Weber’s theory of “elective affinities” and adapt it to the Anthropocene, to make the case that in a fragmented society, people and communities of convenience tend to choose the tropes and framing from the dominant culture to justify self-interested action. That often can take the form of religious discourse. In the sense of finding a wide array of practical interpretations relative to the environment, the theory is largely supported, although we do find important nuances. It is instructive to look at how the language and legitimacy of one institution (e.g. religion) has been used to justify and legitimate that of others (e.g. the polity). While these processes of institutional co-optation can be effective in the short run, they may have corrosive longer-term effects. Key rhetorical, and in fact political, battles in the Third Millennium, will likely be organized around how to adapt pre-industrial religion to late industrial and perhaps post-industrial times, and it remains to see how central the natural environment will be in what communities hold sacred

Is Islam Pro- or Anti-Environmental? Interpretations and Implications

Religion has, throughout the centuries, been a powerful institution on the macro level, yet also stands as a force having significant influence in people’s personal lives. This does, however, lead to questions of how a traditional institution such as religion may or may not be adequate to address problems of the Late Industrial Era, most notably the environmental crisis. In this paper, we inquire how various dimensions of Islamic literature and thought can contribute to preserving the natural environment. We find that concepts such as “dominion of men over the earth” and “specialness of humankind” can lead to anti-environmental interpretations of Islam. Nevertheless, other interpretations of Islamic teachings emerge that are compatible with environmental stewardship. However, a number of Islamic governments have shown a decided bias against environmental stewardship, particularly in cases where there is an authoritarian government and one placing an emphasis on economic “development”. In counterpoint, Islamic Mysticism, or Sufism, can provide a spiritual context for environmentally conscious action

Investigation of methods to produce a uniform cloud of fuel particles in a flame tube

The combustion of a uniform, quiescent cloud of 30-micron fuel particles in a flame tube was proposed as a space-based, low-gravity experiment. The subject is the normal- and low-gravity testing of several methods to produce such a cloud, including telescoping propeller fans, air pumps, axial and quadrature acoustical speakers, and combinations of these devices. When operated in steady state, none of the methods produced an acceptably uniform cloud (+ or - 5 percent of the mean concentration), and voids in the cloud were clearly visible. In some cases, severe particle agglomeration was observed; however, these clusters could be broken apart by a short acoustic burst from an axially in-line speaker. Analyses and experiments reported elsewhere suggest that transient, acoustic mixing methods can enhance cloud uniformity while minimizing particle agglomeration

Complementary Ecologies of Being: Quakerism and Buddhism as Exemplars of a Planetist Analogical Imagination

In the face of burgeoning environmental crises in the Anthropocene Age, this paper explores ecological perspectives within Buddhism and Quakerism. These two religious traditions reflect a planetist ethic by emphasizing environmental stewardship in both their canonical writings and their religious structures and practices. Conceptually, this paper contrasts these traditions to the “economism” ethic developed by John Cobb. Through tenets that include simplicity, reverence for nature, and honoring the interconnectedness of life, Buddhism and Quakerism promote environmentally conscious behavior. Across these religious traditions, that compassion and healing can be a path forward in the face of ego-based environmental consumption. In exploring these two religious traditions that have more developed ecological threads, this paper considers sustainable environmental ethics in the Anthropocene Age
