Direct electron transfer-type bioelectrocatalytic dioxygen reduction with copper efflux oxidase lacking type I copper

open access: yesElectrochemistry Communications
Copper efflux oxidase (CueO) is a direct electron transfer (DET)-type bioelectrocatalyst used for dioxygen (O2) reduction. Type I copper (T1Cu) has been suggested to be essential for donating electrons to trinuclear copper center (TNC) during the ...

Fast Hessenberg reduction of some rank structured matrices

open access: yes, 2016
We develop two fast algorithms for Hessenberg reduction of a structured matrix $A = D + UV^H$ where $D$ is a real or unitary $n \times n$ diagonal matrix and $U, V \in\mathbb{C}^{n \times k}$.

Sign-changing concentration phenomena of an anisotropic sinh-Poisson type equation with a Hardy or Hénon term

open access: yesBoundary Value Problems
We consider the following anisotropic sinh-Poisson type equation with a Hardy or Hénon term: 0.1 { − div ( a ( x ) ∇ u ) + a ( x ) u = ε 2 a ( x ) | x − q | 2 α ( e u − e − u ) in  Ω , ∂ u ∂ n = 0 , on  Ω , $$ \left \{ \textstyle\begin{array}{l@{\quad}l}

Reduced auger recombination in mid-infrared semiconductor lasers [PDF]

open access: yes, 2011
A quantum-design approach to reduce the Auger losses in two micron InGaSb type-I quantum well edge-emitting lasers is reported. Experimentally realized structures show a 3X reduction in the threshold, which results in 4.6 lower Auger current loss at room

Time-lagged autoencoders: Deep learning of slow collective variables for molecular kinetics

open access: yes, 2017
Inspired by the success of deep learning techniques in the physical and chemical sciences, we apply a modification of an autoencoder type deep neural network to the task of dimension reduction of molecular dynamics data.

Feasibility of nonlinear absorbers for transient vibration reduction [PDF]

open access: yes, 2010
Torsional vibrations are a cause of severe damage to flexible couplings and gearboxes of a dredger drive line. In this paper the feasibility of three different vibration absorbers is discussed when reducing transient vibrations originating from sudden ...

"Root" Action for N=4 Supersymmetric Mechanics Theories

open access: yes, 2005
We propose to consider the N=4,d=1 supermultiplet with $% (4,4,0) component content as a ``root'' one. We elaborate a new reduction scheme from the ``root'' multiplet to supermultiplets with a smaller number of physical bosons.
