A Unified Treatment of Quasi-Exactly Solvable Potentials II: Eckart Type Potentials [PDF]

open access: yesUnpublished (2002), 2005
This work continues to study the set of quasi exactly solvable potentials related to the Eckart, Hult\'{e}n, Rosen-Morse, Coulomb and the harmonic oscillator potentials. We solve the Schr\"{o}dinger equation for each potential and obtain the eigenvalues and eigenstates in terms of the orthogonal polynomials.

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

open access: yesAdvanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.

Quantum Stationary Hamilton Jacobi Equation in 3-D for symmetrical potentials. Introduction of the Spin [PDF]

open access: yesarXiv, 2001
We establish the quantum stationary Hamilton-Jacobi equation in 3-D and its solutions for three symmetrical potentials, Cartesian symmetry potential, spherical symmetry potential and cylindrical symmetry potential. For the two last potentials, a new interpretation of the Spin is proposed within the framework of trajectory representation.

Expression mechanisms underlying long-term potentiation: a postsynaptic view, 10 years on

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2014
This review focuses on the research that has occurred over the past decade which has solidified a postsynaptic expression mechanism for long-term potentiation (LTP). However, experiments that have suggested a presynaptic component are also summarized. It

Bee Better: The Role of Honey in Modern Wound Care

open access: yesAdvanced Therapeutics, EarlyView.
The use of honey as a wound care agent is controversial but paradoxically increasingly popular. Honey possesses relevant antimicrobial properties and can modulate the immune system. The wound healing properties of honey likely depend on its composition and varies across wound types.

Age-dependent loss of PTP and LTP in the hippocampus of PrP-null mice

open access: yesNeurobiology of Disease, 2003
We have investigated synaptic function in the hippocampus in mice of different ages carrying a null mutation in the PrP gene. Experiments carried out in vivo and in vitro in two laboratories revealed no differences in the ability of juvenile and young ...

Estrogen and Progesterone Replacement Therapy Prevent Methamphetamine-Induced Synaptic Plasticity Impairment in Ovariectomized Rats [PDF]

open access: yesAddiction and Health, 2019
Background: Methamphetamine (METH) is one of the most popular psychostimulants which produce long lasting learning and memory impairment. Previous studies have indicated that estrogen and progesterone replacement therapy attenuate cognitive impairment ...

Regularized One Dimensional Coulomb Potential Induced by the Presence of Minimal Lengths [PDF]

open access: yesarXiv, 2005
In this paper we address the problem of a particle moving in singular one dimensional potentials in the framework of quantum mechanics with minimal length. Using the momentum space representation we solve exactly the Schrodinger equation for the Dirac delta potential and Coulomb potential.

Long-term potentiation and the ageing brain

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
Abstract Ageing is associated with learning and memory impairments. Data are reviewed that suggest that age-related impairments of hippocampal-dependent forms of memory, may be caused, in part, by altered synaptic plasticity mechanisms in the hippocampus, including long-term potentiation (LTP).
