Significant progress has been made in Na-intercalation compounds for rechargeable Na batteries. P2 NaxMO2 layered oxides have been shown to have high capacity, good cyclability, and improved rate capability. In this study, we investigate the diffusion mechanisms in P2 NaxCoO2 using ab initio molecular dynamics simulations and nudged elastic band calculations. We identify the Na diffusion mechan...

Wehavepi = 1,p2 = ,pl+p2 =1,whereasp = 2. Had the equations been written in the opposite order, we should have found pi = 2, P2 = 0, Pl + P2 = 2. This illustrates the fact that PI + + Pr, unlike the rank, is not an invariant. 1 Species is defined in the author's paper "Pfaffian Systems of Species One," Trans. Amer. Math. Soc., 35, 356-71 (1933). 2 Cf. Goursat, E., Probleme de Pfaff, Paris, 291 ...

We study cyclic codes of length pk over GR(p2,m), or equivalently, ideals of the ring GR(p2,m)/ 〈upk − 1〉. We derive a method of representing the ideals, and classify all ideals in the ring GR(p2,m)/ 〈upk − 1〉. We also analyse the duals, and identify the self-dual ideals. © 2008 Elsevier Inc.

Mice were immunized against ribosomal acidic proteins P1 and P2 from Artemia salina, and three kinds of monoclonal antibodies were isolated. One recognized P0 in addition to both P1 and P2 (anti-P). The other two recognized either P1 (anti-P1) or P2 (anti-P2) specifically and did not recognize P0. The anti-P antibody, but not anti-P1 or anti-P2, recognized a 22-amino acid peptide corresponding ...

Objective. Basilar artery (BA) terminates in right and left posterior cerebral arteries (PCAs). Each PCA supplies respective occipital lobe of the cerebrum. The present study is designed to know the morphology, morphometry, branching pattern, and symmetry of PCA. Methods. The study included 340 PCAs dissected from 170 human cadaveric brains. Results. Morphological variations of P1 segment inclu...

Trichosanthin (TCS) is a type I ribosome-inactivating protein that inactivates ribosome by enzymatically depurinating the A(4324) at the alpha-sarcin/ricin loop of 28S rRNA. We have shown in this and previous studies that TCS interacts with human acidic ribosomal proteins P0, P1 and P2, which constitute the lateral stalk of eukaryotic ribosome. Deletion mutagenesis showed that TCS interacts wit...

HPV infections are common and the presence of the same high-risk type in cervical specimens can be due to reinfection or persistence. Persistent infection is the most important predictor for development of cervical carcinoma. The aim of this study was to validate PCR-RFLP with two sets of primers: MY09/MY11 that amplify a fragment of L1 and P1/P2 that amplify a fragment of E1 ORF. PCR product o...

We developed a new method to observe distribution of phosphatidylinositol 3,5-bisphosphate [PtdIns(3,5)P2] using electron microscopy. In freeze-fracture replicas of quick-frozen samples, PtdIns(3,5)P2 was labeled specifically using recombinant ATG18 tagged with glutathione S-transferase and 4×FLAG, which was mixed with an excess of recombinant PX domain to suppress binding of ATG18 to phosphati...

INTRODUCTION AND OBJECTIVES To investigate changes in the clinical characteristics, etiology and prognosis of prosthetic valve endocarditis at a tertiary-care hospital. METHODS Retrospective cohort study of all patients diagnosed with prosthetic valve endocarditis using modified Duke criteria between 1986 and 2005. The analysis covered two time periods: January 1986 to December 1995 (P1) and ...

The inositol lipid phosphatidylinositol (4,5)-bisphosphate [PtdIns(4,5)P2] is involved in a myriad of cellular processes, including the regulation of exocytosis and endocytosis. In this paper, we address the role of PtdIns(4,5)P2 in compound exocytosis from rat peritoneal mast cells. This process involves granule-plasma membrane fusion as well as homotypic granule membrane fusion and occurs wit...
