TL;DR: In this paper, a global discrete-time modeling of the term struc- ture of interest rates is proposed to capture simultaneously the following important features: (i) interest rates with an historical dynamics involving several lagged values, and switch- ing regimes; (ii) a specification of the stochastic discount factor (SDF) with time-varying and regime-dependent risk-premia; (iii) the possibility to derive explicit or quasi explicit formulas for zero-coupon bond and interest rate derivative prices; (iv) the positiveness of
Abstract: Switching VARMA Term Structure Models The purpose of the paper is to propose a global discrete-time modeling of the term struc- ture of interest rates able to capture simultaneously the following important features : (i) interest rates with an historical dynamics involving several lagged values, and switch- ing regimes; (ii) a specification of the stochastic discount factor (SDF) with time-varying and regime-dependent risk-premia; (iii) the possibility to derive explicit or quasi explicit formulas for zero-coupon bond and interest rate derivative prices; (iv) the positiveness of the yields at each maturity. We develop the Switching Autoregressive Normal (SAN) Term Structure model of order p and the Switching Autoregressive Gamma (SAG) Term Structure model of order p, and regime shifts are described by a Markov chain with state- dependent transition probabilities. In both cases multifactor generalizations are proposed.

TL;DR: The good agreement between the institutes suggests that spectroradiometric thermometry techniques are sufficiently mature to allow the direct realization of thermodynamic temperature above 1234 K (rather than the use of a temperature scale) and that metal-carbon eutectics can be used as high-temperature fixed points for thermodynamicTemperature dissemination.
Abstract: The thermodynamic temperature of the point of inflection of the melting transition of Re-C, Pt-C and Co-C eutectics has been determined to be 2747.84 ± 0.35 K, 2011.43 ± 0.18 K and 1597.39 ± 0.13 K, respectively, and the thermodynamic temperature of the freezing transition of Cu has been determined to be 1357.80 ± 0.08 K, where the ± symbol represents 95% coverage. These results are the best consensus estimates obtained from measurements made using various spectroradiometric primary thermometry techniques by nine different national metrology institutes. The good agreement between the institutes suggests that spectroradiometric thermometry techniques are sufficiently mature (at least in those institutes) to allow the direct realization of thermodynamic temperature above 1234 K (rather than the use of a temperature scale) and that metal-carbon eutectics can be used as high-temperature fixed points for thermodynamic temperature dissemination. The results directly support the developing mise en pratique for the definition of the kelvin to include direct measurement of thermodynamic temperature.

TL;DR: Observations suggest a potential unsuspected pathway of host genetic influence on the dynamics of AIDS progression, as observed for SNPs in the gene PARD3B.
Abstract: Background. Host genetic variation influences human immunodeficiency virus (HIV) infection and progression to AIDS. Here we used clinically well-characterized subjects from 5 pretreatment HIV/AIDS cohorts for a genome-wide association study to identify gene associations with rate of AIDS progression.
Methods. European American HIV seroconverters (n = 755) were interrogated for single-nucleotide polymorphisms (SNPs) (n = 700,022) associated with progression to AIDS 1987 (Cox proportional hazards regression analysis, co-dominant model).
Results. Association with slower progression was observed for SNPs in the gene PARD3B. One of these, rs11884476, reached genome-wide significance (relative hazard = 0.3; P =3. 370 × 10−9) after statistical correction for 700,022 SNPs and contributes 4.52% of the overall variance in AIDS progression in this study. Nine of the top-ranked SNPs define a PARD3B haplotype that also displays significant association with progression to AIDS (hazard ratio, 0.3; P = 3.220 × 10−8). One of these SNPs, rs10185378, is a predicted exonic splicing enhancer; significant alteration in the expression profile of PARD3B splicing transcripts was observed in B cell lines with alternate rs10185378 genotypes. This SNP was typed in European cohorts of rapid progressors and was found to be protective for AIDS 1993 definition (odds ratio, 0.43, P = .025).
Conclusions. These observations suggest a potential unsuspected pathway of host genetic influence on the dynamics of AIDS progression.

TL;DR: Study of the 7 alpha-hydroxylating enzyme in these tissues indicated that microsomes contained most of the activity, except for brain, where it was primarily mitochondrial, which will prove to be useful in studies of the enzyme responsible and of the mechanisms that control its activity.
