No full textIrv and Cynthia\u27s 1828 house in Hallowell is surrounded by 48 lilacs planted by former Maine governor, Dr. John Hubbard, in 1865. Lilacs at the Henry Wadsworth Longfellow home in Portland date back to the 19th century, and those in the Portland Street Cemetery in South Berwick, where author Sarah Orne Jewett is buried, date back to 1909. With details on growing lilacs in Maine

John Wesley and Slavery: Myth and Reality
No full text1. Was Wesley opposed to the institution of slavery? Or is that merely myth, because he only opposed the horrors of the slave trade? The reason for this question is that many eighteenth-century persons were greatly opposed to the slave trade, but had no moral difficulty with the institution of slavery.
2. If he opposed slavery, was it the abuses that troubled him, or did he reject the philosophical underpinnings of the institution itself?
3. What is truth and what is myth about Wesley\u27s contemporaries, such as his friend John Newton, author of Amazing Grace, and known as the converted slave trader?
4. Is it myth or reality that Wesley\u27s position was supported by Coke and Asbury on the American scene?
5. And finally, was Wesley\u27s influence on the ending of slavery truly significant, or is that myth
Towards High-Efficiency Thin-Film Solar Cells: from Theoretical Analysis to Experimental Exploration
No full textabstract: GaAs single-junction solar cells have been studied extensively in recent years, and have reached over 28 % efficiency. Further improvement requires an optically thick but physically thin absorber to provide both large short-circuit current and high open-circuit voltage. By detailed simulation, it is concluded that ultra-thin GaAs cells with hundreds of nanometers thickness and reflective back scattering can potentially offer efficiencies greater than 30 %. The 300 nm GaAs solar cell with AlInP/Au reflective back scattering is carefully designed and demonstrates an efficiency of 19.1 %. The device performance is analyzed using the semi-analytical model with Phong distribution implemented to account for non-Lambertian scattering. A Phong exponent m of ~12, a non-radiative lifetime of 130 ns, and a specific series resistivity of 1.2 Ω·cm2 are determined.
Thin-film CdTe solar cells have also attracted lots of attention due to the continuous improvements in their device performance. To address the issue of the lower efficiency record compared to detailed-balance limit, the single-crystalline Cd(Zn)Te/MgCdTe double heterostructures (DH) grown on InSb (100) substrates by molecular beam epitaxy (MBE) are carefully studied. The Cd0.9946Zn0.0054Te alloy lattice-matched to InSb has been demonstrated with a carrier lifetime of 0.34 µs observed in a 3 µm thick Cd0.9946Zn0.0054Te/MgCdTe DH sample. The substantial improvement of lifetime is due to the reduction in misfit dislocation density. The recombination lifetime and interface recombination velocity (IRV) of CdTe/MgxCd1-xTe DHs are investigated. The IRV is found to be dependent on both the MgCdTe barrier height and width due to the thermionic emission and tunneling processes. A record-long carrier lifetime of 2.7 µs and a record-low IRV of close to zero have been confirmed experimentally.
The MgCdTe/Si tandem solar cell is proposed to address the issue of high manufacturing costs and poor performance of thin-film solar cells. The MBE grown MgxCd1-xTe/MgyCd1-yTe DHs have demonstrated the required bandgap energy of 1.7 eV, a carrier lifetime of 11 ns, and an effective IRV of (1.869 ± 0.007) × 103 cm/s. The large IRV is attributed to thermionic-emission induced interface recombination. These understandings can be applied to fabricating the high-efficiency low-cost MgCdTe/Si tandem solar cell.Dissertation/ThesisDoctoral Dissertation Electrical Engineering 201

Effectiveness of XBB.1.5 Vaccines Against Symptomatic SARS-CoV-2 Infection in Older Adults During the JN.1 Lineage-Predominant Period, European VEBIS Primary Care Multicentre Study, 20 November 2023-1 March 2024
No full textWe estimated XBB.1.5 vaccine effectiveness (VE) against symptomatic SARS-CoV-2 infection among adults aged ≥ 65 years during the 2023/2024 JN.1 lineage-predominant period in a European multi-country test-negative case-control study at primary care level. We estimated VE adjusted by study site, age, sex, chronic conditions and onset date. We included 220 cases and 1733 controls. The VE was 48% (95% CI: 12-71), 23% (95% CI: -11-48) and 5% (95% CI: -92-56) among those with symptom onset 1-5, 6-11, and ≥ 12 weeks after vaccination, respectively. XBB.1.5 vaccine provided short and moderate protection against JN.1 symptomatic infection.Funding for this project was received from the European Centre for Disease Prevention and Control (ECDC) implementing Framework Contract ECDC/2021/019 ‘Vaccine effectiveness, burden and impact of COVID-19 and influenza’. The funder of the study had a role in the study design, data interpretation and the review of the manuscript, but no role in data collection or data analysis. The corresponding author had full access to all the data in the study, and final responsibility for the decision to submit for publication was by consensus.S
