NECAP 4.1: NASA's Energy Cost Analysis Program thermal response factor routine

A thermal response factor is described and calculation sequences and flowcharts for RESFAC2 are provided. RESFAC is used by NASA's (NECAP) to calculate hourly heat transfer coefficients (thermal response factors) for each unique delayed surface. NECAP uses these response factors to compute each spaces' hourly heat gain/loss

Scattering lengths of Nambu-Goldstone bosons off DD mesons and dynamically generated heavy-light mesons

Recent lattice QCD simulations of the scattering lengths of Nambu-Goldstone bosons off the $D$ mesons are studied using unitary chiral perturbation theory. We show that the Lattice QCD data are better described in the covariant formulation than in the heavy-meson formulation. The $D^*_{s0}(2317)$ can be dynamically generated from the coupled-channels $DK$ interaction without \textit{a priori} assumption of its existence. A new renormalization scheme is proposed which manifestly satisfies chiral power counting rules and has well-defined behavior in the infinite heavy-quark mass limit. Using this scheme we predict the heavy-quark spin and flavor symmetry counterparts of the $D^*_{s0}(2317)$.Comment: 22 pages, 5 figures; to appear in Physical Review

Thermodynamics of a three-flavor nonlocal Polyakov--Nambu--Jona-Lasinio model

The present work generalizes a nonlocal version of the Polyakov loop-extended Nambu and Jona-Lasinio (PNJL) model to the case of three active quark flavors, with inclusion of the axial U(1) anomaly. Gluon dynamics is incorporated through a gluonic background field, expressed in terms of the Polyakov loop. The thermodynamics of the nonlocal PNJL model accounts for both chiral and deconfinement transitions. Our results obtained in mean-field approximation are compared to lattice QCD results for $N_\text{f}=2+1$ quark flavors. Additional pionic and kaonic contributions to the pressure are calculated in random phase approximation. Finally, this nonlocal 3-flavor PNJL model is applied to the finite density region of the QCD phase diagram. It is confirmed that the existence and location of a critical point in this phase diagram depends sensitively on the strength of the axial U(1) breaking interaction.Comment: 31 pages, 15 figures, minor changes compared to v

Thermodynamics and quark susceptibilities: a Monte-Carlo approach to the PNJL model

The Monte-Carlo method is applied to the Polyakov-loop extended Nambu--Jona-Lasinio (PNJL) model. This leads beyond the saddle-point approximation in a mean-field calculation and introduces fluctuations around the mean fields. We study the impact of fluctuations on the thermodynamics of the model, both in the case of pure gauge theory and including two quark flavors. In the two-flavor case, we calculate the second-order Taylor expansion coefficients of the thermodynamic grand canonical partition function with respect to the quark chemical potential and present a comparison with extrapolations from lattice QCD. We show that the introduction of fluctuations produces only small changes in the behavior of the order parameters for chiral symmetry restoration and the deconfinement transition. On the other hand, we find that fluctuations are necessary in order to reproduce lattice data for the flavor non-diagonal quark susceptibilities. Of particular importance are pion fields, the contribution of which is strictly zero in the saddle point approximation

Breeding birds of the forested portions of Cedarburg Bog

In 1971 the Wisconsin Scientific Areas Preservation Council inaugurated a program of annual breeding bird surveys in the various state scientific areas, carried out by members of the Wisconsin Society for Ornithology and coordinated by Mrs. Evelyn Warner. The object is to provide documented quantitative data for assessment of bird population trends, specifically as an index to possible environmental deterioration. The upland deciduous (maple-beech) woods at the UWM Field Station and a large part of the adjacent Cedarburg Bog are included in the scientific areas system, destined for preservation with minimal management for scientific research and education. As part of the program mentioned above I conducted breeding bird surveys in the bog in 1971, 1972 and 1973 and in the upland woods in 1971, while Dennis Gustafson conducted surveys in the upland woods in 1972 and 1973

The fat and weight cycle in Wisconsin juncos

Our study was aimed at answering three specific questions. First, do wild Juncos in Wisconsin exhibit spring premigratory fat deposition. Second, it has been reported that during the winter, fat deposits and body weights are high during cold periods and lower during warm spells: in other words fat condition is inversely temperature-dependent. Our second objective then was to get large samples of weights and fat conditions under a variety of winter weather conditions in order to test the reality of the inverse temperature-dependence claimed by others. Third, we wanted to investigate the diurnal patterns of fat deposition
