The latency of human immunodeficiency virus type 1 (HIV-1) in resting primary CD4+ T cells is the major barrier for the eradication of the virus in patients on suppressive highly active antiretroviral therapy (HAART). Even with optimal HAART treatment, replication-competent HIV-1 still exists in resting primary CD4+ T cells. Multiple restriction factors(More)
The apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 3G (APOBEC3G or A3G) and its fellow cytidine deaminase family members are potent restrictive factors for human immunodeficiency virus type 1 (HIV-1) and many other retroviruses. A3G interacts with a vast spectrum of RNA-binding proteins and is located in processing bodies and stress(More)
This study illustrates aesthetic and sensory reconstruction of finger pulp defects with free toe flaps from the lateral aspect of the great toe or the medial aspect of the second toe. Between August 2007 and July 2010, free toe flaps were harvested and used for 21 fingers of 21 patients. The average patient age was 34.5 years (range 19–62 years). The soft(More)
Basing on our hierarchical equations of motion for time-dependent quantum transport [X. Zheng, G. H. Chen, Y. Mo, S. K. Koo, H. Tian, C. Y. Yam, and Y. J. Yan, J. Chem. Phys. 133, 114101 (2010)], we develop an efficient and accurate numerical algorithm to solve the Liouville-von-Neumann equation. We solve the real-time evolution of the reduced(More)
Based on our earlier works [X. Zheng et al., Phys. Rev. B 75, 195127 (2007); J. S. Jin et al., J. Chem. Phys. 128, 234703 (2008)], we propose a rigorous and numerically convenient approach to simulate time-dependent quantum transport from first-principles. The proposed approach combines time-dependent density functional theory with quantum dissipation(More)
Application of quantum dissipation theory to electronic dynamics has been limited to model systems with few energy levels, and its numerical solutions are mostly restricted to high temperatures. A highly accurate and efficient numerical algorithm, which is based on the Chebyshev spectral method, is developed to integrate a single-particle Liouville-von(More)
This study reports our experience with reconstruction of distal fingertip degloving injuries using a single cross-finger flap based on the dorsal branch of the proper digital artery at the middle phalanx. From January 2009 to October 2011, 18 patients (18 fingers) presented with distal fingertip degloving injuries and were treated with this technique. The(More)
Memristor, memcapacitor, and meminductor are new fundamental circuit elements, whose properties depend on the history of devices. This paper presents the physical analysis of these memory devices. Three simple examples are given for the memristor, memcapacitor, and meminductor, and are then generalized to reveal their general physical origin. It is found(More)
The primary issue in molecular electronics is measuring and understanding how electrons travel through a single molecule strung between two electrodes. A key area involves electronic interference that occurs when electrons can follow more than one pathway through the molecular entity. When the phases developed along parallel pathways are inequivalent,(More)
The goal of this study is to propose a reliability centered predictive maintenance scheme for a complex structure Inertial Navigation System (INS) with several redundant components. GO Methodology is applied to build the INS reliability analysis model—GO chart. Components Remaining Useful Life (RUL) and system reliability are updated dynamically based on(More)
