Dual response of BDNF to sublethal concentrations of β-amyloid peptides in cultured cortical neurons

Autor: E. Aliaga, M. Silhol, N. Bonneau, T. Maurice, S. Arancibia, L. Tapia-Arancibia

Publikováno v: Neurobiology of Disease, Vol 37, Iss 1, Pp 208-217 (2010)

Beta-amyloid (Aβ) deposition is one important pathological hallmark in Alzheimer's disease (AD). However, low levels of Aβ may modify critical endogenous protection systems before neurodegeneration occurs. We examined the time-course effect of subl

Protective effect of BDNF against beta-amyloid induced neurotoxicity in vitro and in vivo in rats

Autor: S. Arancibia, M. Silhol, F. Moulière, J. Meffre, I. Höllinger, T. Maurice, L. Tapia-Arancibia

Publikováno v: Neurobiology of Disease, Vol 31, Iss 3, Pp 316-326 (2008)

We examined the potential protective effect of BDNF against β-amyloid-induced neurotoxicity in vitro and in vivo in rats. In neuronal cultures, BDNF had specific and dose–response protective effects on neuronal toxicity induced by Aβ1–42 and A�

Anomalies in the pseudogap phase of the cuprates: Competing ground states and the role of umklapp scattering

Autor: Robinson, Neil J., Johnson, Peter D., Rice, T. Maurice, Tsvelik, Alexei M.

Publikováno v: Rep. Prog. Phys. 82, 126501 (2019)

Over the past two decades, advances in computational algorithms have revealed a curious property of the two-dimensional Hubbard model (and related theories) with hole doping: the presence of close-in-energy competing ground states that display very d

Report

Umklapp scattering as the origin of $T$-linear resistivity in the normal state of high-$T_c$ cuprate superconductors

Autor: Rice, T. Maurice, Robinson, Neil J., Tsvelik, Alexei M.

Publikováno v: Phys. Rev. B 96, 220502 (2017)

The high-temperature normal state of the unconventional cuprate superconductors has resistivity linear in temperature $T$, which persists to values well beyond the Mott-Ioffe-Regel upper bound. At low-temperature, within the pseudogap phase, the resi

Superconductivity close to the Mott state: From condensed-matter systems to superfluidity in optical lattices

Autor: Hur, Karyn Le, Rice, T. Maurice

Publikováno v: Annals of Physics 324 (2009) 1452

Since the discovery of high-temperature superconductivity in 1986 by Bednorz and Mueller, great efforts have been devoted to finding out how and why it works. From the d-wave symmetry of the order parameter, the importance of antiferromagnetic fluctu

Superconductivity in the Two-Dimensional $t$-$J$ Model at Low Hole Doping

Autor: Heeb, Elmar S., Rice, T. Maurice

By combining a generalized Lanczos scheme with the variational Monte Carlo method we can optimize the short- and long-range properties of the groundstate separately. This allows us to measure the long-range order of the groundstate of the $t$-$J$ mod

Pairing and Excitation Spectrum in doped t-J Ladders

Autor: Tsunetsugu, Hirokazu, Troyer, Matthias, Rice, T. Maurice

Publikováno v: Phys. Rev. B 49, 016078 (1994)

Exact diagonalization studies for a doped t-J ladder (or double chain) show hole pairing in the ground state. The excitation spectrum separates into a limited number of quasiparticles which carry charge $+|e|$ and spin ${1 \over 2}$ and a triplet mod
