Southern Adventist University is a Seventh-day Adventist college in Collegedale, Tennessee, owned and operated by the Southern Union Conference of Seventh-day Adventists. U.S. News & World Report categorizes it as a Southern Regional College, and the magazine has consistently ranked it as one of the top-tier schools in that category. Southern Adventist University occupies a 1,000 acres campus in a rural setting in the Tennessee River Valley.It was founded in 1892 in Graysville, Tennessee, as Graysville Academy and was the first Adventist school in the southern U.S. Due to the need for additional space for expansion the school relocated in 1916 and was renamed Southern Junior College. In 1944 Southern began awarding baccalaureate degrees and was renamed Southern Missionary College. In 1996 the institution started conferring Masters degrees and adopted its current name.Southern offers associate, baccalaureate, master's, and doctoral degrees. It is accredited by multiple organizations including the Commission on Colleges of the Southern Association of Colleges and Schools. Its Institute of Archaeology offers an undergraduate degree in biblical archaeology; Southern is one of only two schools which offer the degree. It is known for its emphasis on Adventist beliefs and conservative religious and social practices, and is considered the most conservative of the Seventh-day Adventist schools in North America. The college operates a radio station , a health food store and a wellness center. Enrollment was 3,053 students in 2010, its highest level to date. Wikipedia.

We consider in this work the electromagnetic current for a system composed of two charged bosons and show that it has a structure of many bodies even in the impulse approximation, when described in the light-front time x+. In terms of the two-body component for the bound state, the current contains two-body operators. We consider the photon interacting with two bosons and the process of pair creation connected to this interaction, interpreting it as a zero mode contribution to the current and discuss the consequences of this pair creation to the components of currents in the light front. © 2013 American Physical Society.

Least-squares forecasts for vibration frequencies of diatomic molecules, most with 10-12 valence electrons, are combined with those obtained from neural networks, both trained on critical data. It is required that the standard deviation bounds of the one prediction lie within the bounds of the other; this requirement results in 69 molecules, 50 of which may not have been studied before. The composite standard deviations of the composite predictions average 5.9%, so there is a 68% chance that each of these 50 predictions will prove to be within 5.9% of its ultimately correct value. As a test, 28 literature values, for 12 of the molecules, were found; of these 28 values, 78.6% fall between the lower and upper composite standard deviation limits. © 2009 Elsevier Ltd.

Different mathematical methods have been applied to obtain the analytic result for the massless triangle Feynman diagram yielding a sum of four linearly independent (LI) hypergeometric functions of two variables F4. This result is not physically acceptable when it is embedded in higher loops, because all four hypergeometric functions in the triangle result have the same region of convergence and further integration means going outside those regions of convergence. We could go outside those regions by using the well-known analytic continuation formulas obeyed by the F4, but there are at least two ways we can do this. Which is the correct one? Whichever continuation one uses, it reduces a number of F4 from four to three. This reduction in the number of hypergeometric functions can be understood by taking into account the fundamental physical constraint imposed by the conservation of momenta flowing along the three legs of the diagram. With this, the number of overall LI functions that enter the most general solution must reduce accordingly. It remains to determine which set of three LI solutions needs to be taken. To determine the exact structure and content of the analytic solution for the three-point function that can be embedded in higher loops, we use the analogy that exists between Feynman diagrams and electric circuit networks, in which the electric current flowing in the network plays the role of the momentum flowing in the lines of a Feynman diagram. This analogy is employed to define exactly which three out of the four hypergeometric functions are relevant to the analytic solution for the Feynman diagram. The analogy is built based on the equivalence between electric resistance circuit networks of types Y and Δ in which flows a conserved current. The equivalence is established via the theorem of minimum energy dissipation within circuits having these structures. Source

In this work we consider the propagation of two fermion fields interacting with each other by the exchange of intermediate scalar bosons in the light front. We obtain the corrections up to fourth order in the coupling constant using hierarchical equations in order to obtain the bound state equation (Bethe - Salpeter equation). © 2013 Chinese Physical Society and IOP Publishing Ltd.

Chagas disease is endemic in Latin America and an emerging infectious disease in the United States. No effective treatments are available. The TcG1, TcG2, and TcG4 antigens are highly conserved in clinically relevant Trypanosoma cruzi isolates and are recognized by B and T cells in infected hosts. Delivery of these antigens as a DNA prime/protein boost vaccine (TcVac2) elicited lytic antibodies and type 1 CD8+ T cells that expanded upon challenge infection and provided >90% control of parasite burden and myocarditis in chagasic mice. Here we determined if peripheral blood can be utilized to capture the TcVac2-induced protection from Chagas disease. We evaluated the serum levels of T. cruzi kinetoplast DNA (TckDNA), T. cruzi 18S ribosomal DNA (Tc18SrDNA), and murine mitochondrial DNA (mtDNA) as indicators of parasite persistence and tissue damage and monitored the effect of sera on macrophage phenotype. Circulating TckDNA/Tc18SrDNA and mtDNA were decreased by >3- to 5-fold and 2-fold, respectively, in vaccinated infected mice compared to nonvaccinated infected mice. Macrophages incubated with sera from vaccinated infected mice exhibited M2 surface markers (CD16, CD32, CD200, and CD206), moderate proliferation, a low oxidative/nitrosative burst, and a regulatory/anti-inflammatory cytokine response (interleukin-4 [IL-4] plus IL-10 > tumor necrosis factor alpha [TNF-α]). In comparison, macrophages incubated with sera from nonvaccinated infected mice exhibited M1 surface markers, vigorous proliferation, a substantial oxidative/nitrosative burst, and a proinflammatory cytokine response (TNF-α»IL-4 plus IL-10). Cardiac infiltration of macrophages and TNF-α and oxidant levels were significantly reduced in TcVac2-immunized chagasic mice. We conclude that circulating TcDNA and mtDNA levels and macrophage phenotype mediated by serum constituents reflect in vivo levels of parasite persistence, tissue damage, and inflammatory/anti-inflammatory state and have potential utility in evaluating disease severity and efficacy of vaccines and drug therapies. © 2014, American Society for Microbiology.
