View from the bridge: a pseudo-Jahn-Teller approach to transition metal hydrosilane complexes
No full textThe model complex [Cp(CO)(2)Mn(SiH4)] has been studied by time-dependent DFT methods: hence, it is shown to be unstable with respect to a pseudo-Jahn-Teller distortion which brings an equatorial Si-H moiety into contact with the Mn centre.</p
O'Hare International Airport; United Airlines Terminal
No full textExposed trusses and pipes, all painted white; United and American both established nationwide hubs at the airport in the 1980s, which continue to operate today. United developed a new $500 million Terminal 1 ("The Terminal of the Future" or "Terminal of Tomorrow") designed by Helmut Jahn and A. Epstein and Sons, with Turner Construction as the construction manager, and Thornton Tomasetti serving as the structural engineer. Jahn described his design as drawing inspiration from the exhibition halls and railway stations of the turn of the twentieth century, with open floor space and lots of natural light. The 850 ft. tunnel connecting Concourse B and C, also designed by Jahn, has become one of O’Hare’s defining features. Jahn worked with artist Michael Hayden and composer William Kraft to design the complex light sculpture called “Sky’s the Limit,” which covers the ceiling of the tunnel and undulates to music, computer controlled. It includes 466 neon tubes and lighted panels. Source: Wikipedia; http://en.wikipedia.org/wiki/Main_Page (accessed 3/30/2014
Estimating the need for antiretroviral treatment and an assessment of a simplified HIV/AIDS case definition in rural Malawi.
No full textBACKGROUND: Surveillance in the era of antiretroviral therapy (ART) requires estimates of HIV prevalence as well as the proportion eligible for ART. We estimated HIV prevalence and assessed field staging of individuals to estimate the burden of HIV disease needing treatment in rural Malawi. METHODS: Adults aged 18-59 years in a demographic surveillance system were interviewed, examined, and HIV counselled and tested. Staging that used a simplified version of the WHO criteria ('field checklist') was compared with staging by a medical assistant using a 'clinic checklist' and to CD4 cell results. RESULTS: A total of 2129 of 2303 eligible adults (92.4%) were traced, and 2047 (96.1%) participated. Of the 1443 participants (70.5%) tested, 11.6% were HIV positive. ART eligibility classification by the field and clinic checklists were concordant in 122 of 133 HIV-positive individuals. Compared with the clinic checklist, the field checklist had a sensitivity of 50% and a specificity of 96%. Including those already known to be on ART, staging by the field and clinic checklists estimated ART eligibility at 16.3 and 17.7% of HIV-positive individuals, respectively. Using CD4 cell count under 250 cells/mul or WHO stage III/IV, the Malawi national programme criteria, 38% of HIV-positive individuals were eligible for ART, compared with 31% based on the 2006 WHO criteria of CD4 cell count under 200 cells/mul or WHO stage IV or CD4 cell count of 200-350 cells/mul and WHO stage III. CONCLUSION: The field checklist was not a suitable tool for individual staging. Criteria for ART eligibility based on clinical staging alone missed two-thirds of those eligible by clinical staging and CD4 cell count

Dynamic Jahn-Teller Effect in Fullerene C{sub 60}
No full textBased on the Bogoliubov-de Gennes formalism, the linear multi-mode T{sub 1u} {circle_times} 8h{sub g} static Jahn-Teller problem is analyzed for the charged C{sub 60}{sup {minus}}, C{sub 60}{sup 2{minus}}, the lowest triplet and singlet self-trapped exciton (STE) of C{sub 60}. The dynamic Jahn-Teller effect due to quantum tunneling between the six degenerate D{sub 5d} configurations is studied within a perturbation approach. The tunneling induced level splittings are determined to be {sup 2}T{sub 1u} {circle_plus} {sup 2}T{sub 3u}, {sup 1}A{sub g} {circle_plus} {sup 1}H{sub g}, {sup 3}T{sub 3g} {circle_plus} {sup 3}T{sub 1g} and {sup 1}T{sub 3g} {circle_plus} {sup 1}T{sub 1g} for C{sub 60}{sup 1{minus}}, C{sub 60}{sup 2{minus}}, triplet and singlet STE`s of neutral C{sub 60}, respectively. The observable consequences of the dynamic Jahn-Teller effect are considered. Some of the Jahn-Teller active (as well as Raman-active) modes are predicted to be observable as multi-phonon overtones in the infrared absorption. In the photo-induced multi-phonon resonant Raman scattering the tunnel splitting itself should show up in the Raman spectrum, and the depolarization ratio is sensitive to the exciting frequency
Population-level effect of HIV on adult mortality and early evidence of reversal after introduction of antiretroviral therapy in Malawi.
No full textBACKGROUND: Malawi, which has about 80,000 deaths from AIDS every year, made free antiretroviral therapy available to more than 80 000 patients between 2004 and 2006. We aimed to investigate mortality in a population before and after the introduction of free antiretroviral therapy, and therefore to assess the effects of such programmes on survival at the population level. METHODS: We used a demographic surveillance system to measure mortality in a population of 32,000 in northern Malawi, from August, 2002, when free antiretroviral therapy was not available in the study district, until February, 2006, 8 months after a clinic opened. Causes of death were established through verbal autopsies (retrospective interviews). Patients who registered for antiretroviral therapy at the clinic were identified and linked to the population under surveillance. Trends in mortality were analysed by age, sex, cause of death, and zone of residence. FINDINGS: Before antiretroviral therapy became available in June, 2005, mortality in adults (aged 15-59 years) was 9.8 deaths for 1000 person-years of observation (95% CI 8.9-10.9). The probability of dying between the ages of 15 and 60 years was 43% (39-49) for men and 43% (38-47) for women; 229 of 352 deaths (65.1%) were attributed to AIDS. 8 months after the clinic that provided antiretroviral therapy opened, 107 adults from the study population had accessed treatment, out of an estimated 334 in need of treatment. Overall mortality in adults had decreased by 10% from 10.2 to 8.7 deaths for 1000 person-years of observation (adjusted rate ratio 0.90, 95% CI 0.70-1.14). Mortality was reduced by 35% (adjusted rate ratio 0.65, 0.46-0.92) in adults near the main road, where mortality before antiretroviral therapy was highest (from 13.2 to 8.5 deaths per 1000 person-years of observation before and after antiretroviral therapy). Mortality in adults aged 60 years or older did not change. INTERPRETATION: Our findings of a reduction in mortality in adults aged between 15 and 59 years, with no change in those older than 60 years, suggests that deaths from AIDS were averted by the rapid scale-up of free antiretroviral therapy in rural Malawi, which led to a decline in adult mortality that was detectable at the population level

Internal friction investigation of phase transformation in nearly stoichiometric LaMnO3+δ
No full textRhombohedral LaMnO3+δ powders, prepared by two different soft chemistry routes (co-precipitation and hydrothermal synthesis), are sintered at 1400 °C for 2 h in air. Measurements of internal friction Q−1(T) and shear modulus G(T), at low frequencies from −180 to 700 °C under vacuum, evidence three structural transitions of nearly stoichiometric orthorhombic LaMnO3+δ. The first one, at 250 or 290 °C, depending on the processing followed, is associated to either a Jahn–Teller structural transition or a phase transformation from orthorhombic to pseudo-cubic. The second one at 610 or 630 °C is related to a phase transformation from pseudo-cubic or orthorhombic to rhombohedral. Below the Neel temperature, around −170 °C, a relaxation peak could be associated, for samples prepared according to both processing routes, to the motion of Weiss domains
E circle times e Jahn-Teller effect in C-70(3-) systems
No full textThe electron-phonon interaction in C-70 anions is studied by making use of a lattice We find there exists a Jahn-Teller effect in C-70(3-) system, due to an extra electron being doped to the double degenerate E-1 '' state. As a result of this effect, the original D-5h symmetry of the ground state becomes unstable, which causes distortion of the lattice configuration. The only symmetry maintained in the final state of the relaxation is the x-y plane reflection symmetry. We further find that besides the Jahn-Teller active A(1)', A(2)' E-2' modes, the non-Jahn-Teller active E-1' vibrations also contribute to the relaxation process. The E-1' components come from the nonlinear effect and are two or three orders smaller than those of the Jahn-Teller active modes. We suggest that the C-70(3-) molecule is a promising Berry Phase candidate in this effective E x e Jahn-Teller system.Physics, AppliedPhysics, Condensed MatterPhysics, MathematicalSCI(E)2ARTICLE161969-19781
