Electronic Structures of Group 9 Metallocorroles with Axial Ammines [PDF]

open access: yes, 2011
The electronic structures of metallocorroles (tpfc)M(NH_3)_2 and (tfc)M(NH_3)_2 (tpfc is the trianion of 5,10,15-(tris)pentafluorophenylcorrole, tfc is the trianion of 5,10,15-trifluorocorrole, and M = Co, Rh, Ir) have been computed using first ...

On photon statistics parametrized by a non-central Wishart random matrix

open access: yes, 2015
In order to tackle parameter estimation of photocounting distributions, polykays of acting intensities are proposed as a new tool for computing photon statistics.

Continuous Family of Invariant Subspaces for R-diagonal Operators

open access: yes, 2001
We show that every R-diagonal operator x has a continuous family of invariant subspaces relative to the von Neumann algebra generated by x. This allows us to find the Brown measure of x and to find a new conceptual proof that Voiculescu's S-transform is ...

Controlling stress state of a hoisting shaft frame in the context of specific freezing process [PDF]

open access: yes, 2018
Purpose is to obtain regularities of a stress state of such multilayer system as neighbourhood rock mass – frozen soil – hoisting shaft frame in the process of numerical analysis to control a frame state with the selection of efficient parameters ...

Waltzing peakons and compacton pairs in a cross-coupled Camassa-Holm equation

open access: yes, 2011
We consider singular solutions of a system of two cross-coupled Camassa-Holm (CCCH) equations. This CCCH system admits peakon solutions, but it is not in the two-component CH integrable hierarchy.

The ring-opening polymerization of D,L-lactide in the melt initiated with tetraphenyltin [PDF]

open access: yes, 1984
Melt polymerization conditions for D,L-lactide initiated with tetraphenyltin were studied with regard to polymer molecular weight and weight distributions.

Queue-length balance equations in multiclass multiserver queues and their generalizations [PDF]

open access: yes, 2016
A classical result for the steady-state queue-length distribution of single-class queueing systems is the following: the distribution of the queue length just before an arrival epoch equals the distribution of the queue length just after a departure ...

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

open access: yesAdvanced Engineering Materials, EarlyView.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.

The malaria parasite cyclic GMP-dependent protein kinase plays a central role in blood-stage schizogony. [PDF]

open access: yes, 2009
A role for the Plasmodium falciparum cyclic GMP (cGMP)-dependent protein kinase (PfPKG) in gametogenesis in the malaria parasite was elucidated previously. In the present study we examined the role of PfPKG in the asexual blood-stage of the parasite life
