Eigenvalues and expectation values for the 1s22s 2S, 1s22p 2P, and 1s23d 2D states of lithium.

Abstract: High-precision variational eigenvalues for the 1${\mathit{s}}^{2}$2s${\mathrm{}}^{2}$S, 1${\mathit{s}}^{2}$2p${\mathrm{}}^{2}$P, and 1${\mathit{s}}^{2}$3d${\mathrm{}}^{2}$D states of lithium are calculated using multiple basis sets in Hylleraas coordinates. Convergence to a few parts in ${10}^{10}$--${10}^{11}$ is achieved. The nonrelativistic energies for infinite nuclear mass are -7.478 060 323 10(31) a.u. for the 1${\mathit{s}}^{2}$2s${\mathrm{}}^{2}$S state, -7.410 156 521 8(13) a.u. for the 1${\mathit{s}}^{2}$2p${\mathrm{}}^{2}$P state, and -7.335 523 541 10(43) a.u. for the 1${\mathit{s}}^{2}$3d${\mathrm{}}^{2}$D state. The corresponding specific isotope shifts due to mass polarization are also calculated with similar accuracy. The 1${\mathit{s}}^{2}$2s${\mathrm{}}^{2}$S--1${\mathit{s}}^{2}$2p${\mathrm{}}^{2}$P and 1${\mathit{s}}^{2}$2p${\mathrm{}}^{2}$P--1${\mathit{s}}^{2}$3d${\mathrm{}}^{2}$D transition energies for $^{7}\mathrm{Li}$ and $^{6}\mathrm{Li}$, as well as the isotope shifts, are calculated and compared with experiment. The results yield an improved ionization potential for lithium of 43 487.167(4) ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$. Expectation values of powers of ${\mathit{r}}_{\mathit{i}}$ and ${\mathit{r}}_{\mathit{ij}}$ and the delta functions \ensuremath{\delta}(${\mathit{r}}_{\mathit{i}}$) and \ensuremath{\delta}(${\mathit{r}}_{\mathit{ij}}$) are evaluated.

An international comparison of cancer survival: Toronto, Ontario, and Detroit, Michigan, metropolitan areas

Abstract: This study examines differences in cancer mortality by socioeconomic status between the United States and Canada. "The Ontario Cancer Registry and the National Cancer Institutes Surveillance Epidemiology and End Results (SEER) program provided a total of 58202 and 76055 population-based primary malignant cancer cases for Toronto Ontario and Detroit Mich respectively....In the U.S. cohort there was a significant association between socioeconomic status and survival for 12 of the 15 most common cancer sites; in the Canadian cohort there was no such association for 12 of the 15 sites. Among residents of low-income areas persons in Toronto experienced a survival advantage for 13 of 15 cancer sites at 1- and 5-year follow-up. No such between-country differentials were observed in the middle- or high-income groups. The consistent pattern of a survival advantage in Canada observed across various cancer sites and follow-up periods suggests that Canadas more equitable access to preventive and therapeutic health care services is responsible for the difference."

Designing and Prototyping a Novel Five-Phase Pancake-Shaped Axial-Flux SRM for Electric Vehicle Application Through Dynamic FEA Incorporating Flux-Tube Modeling

Abstract: Switched reluctance motors (SRMs) show crucial attributes to applications where light weight, high-temperature adaptability, fault-tolerance capability, ruggedness, and simplicity are strongly required. The axial-flux configuration of SRM has additional features over the radial-flux configuration. This paper presents the design and analysis of a novel axial-flux SRM. Detailed procedures of deriving the output power equation as a function of the motor dimensions and parameters are provided. A modified phase winding design approach is thoroughly explained, a flowchart describing the design algorithm is presented, and the inductance determination by different methods is verified experimentally. The 3-D finite-element analysis (FEA) unveils the excessive end core and radial-flux fringing effects in the axial-flux configuration. An exclusive pole-shape design is also proposed. The operation of the motion model using 3-D dynamic FEA is analyzed, and its prototype development process and static testing are demonstrated.
