Forming upon absorption of a UV photon, excited states of DNA are subject to nonadiabatic evolution, via either internal conversion (IC) back to the ground state or mutagenesis. Nonadiabatic processes following the formation of the first singlet excited states, S1, in 10 different small DNA fragments--4 single 4'H-nucleosides, 2 Watson-Crick base pairs, and 4 nucleotide quartets--have been inve...

This paper deals with a wind-based stand-alone generating unit with Permanent Magnet Synchronous Generator (PMSG) and a Lead Acid Battery (LAB) for energy storage, during wind speed variation as well as transient performance under variable load. The main purpose is to supply 230 V/50 Hz domestic appliances through a single-phase inverter. Simulations and experimental results validate the stabil...

In order to correctly predict and evaluate the response of wave energy converters (WECs), an accurate representation of wave climate resource is crucial. This paper gives an overview of wave resource modeling techniques and applies a methodology to estimate the naturally available and technically recoverable resource in a given deployment site. The methodology was initially developed by the Ele...

This special issue presents a review of recent advances in electrochemical energy storage, battery management systems, and power electronics for grid-scale energy storage applications. The importance of energy storage across the entire electricity infrastructure is growing rapidly. In particular, this is highlighted by the urgent need to address the intermittency challenge caused by the large-s...

In this research paper an energy system composed of three energy conversion devices namely, photovoltaic panels, a wind turbine, and a battery is proposed. This controller directs power to a fixed voltage DC bus. The fixed voltage bus supplies the load, while the excess power is directed to the batteries. Simulation and control of a hybrid PVwind generator system connected to the load are prese...

A number of studies of high-Tc superconductors show that cuprate superconductors have a short coherence length, comparable to the average distance between doped holes. While this observation casts doubt on the applicability of the BCS model, the limit of local pairs is not a good description of the cuprates either, as the existence of a Fermi surface demonstrates. A more appropriate model of a ...
