Commercializing university research in transition economies: technology transfer offices or direct industrial funding?
There is a paucity of knowledge on research commercialization by university scientists worldwide. The objective of this paper is to identify the role that Technology Transfer Offices (TTOs) and direct Industrial Funding play in university research commercialization in transition economies of Azerbaijan, Belarus and Kazakhstan during 2015–2017. We do this by developing a novel database and a multi-level model which explains how individual attributes, organizational and ecosystem characteristics explain the extent of knowledge commercialization.
We apply the generalized Heckman approach to account for two selection biases, reducing the sample from 2602 to 272 scientists, and further use a mixed-method approach to analyse 27 face-to-face interviews with researchers and TTO managers. The results demonstrate that research commercialization is not associated with the existence and awareness of TTO or the establishment of commercialization contracts via TTO, but the direct industrial funding of university research. Taken together the findings have clear implications for scholars, scientific entrepreneurs, TTOs and investors who aim to exploit university knowledge in transition economies
Local stress and elastic properties of lipid membranes obtained from elastic energy variation
A theory and computational method are provided for the calculation of lipid
membranes elastic parameters, which overcomes the difficulties of the existing
approaches and can be applied not only to single-component but also to
multi-component membranes. It is shown that the major elastic parameters can be
determined as the derivatives of the stress-profile moments with respect to
stretching. The more general assumption of the global incompressibility,
instead of the local one, is employed, which allows the measurement of the
local Poisson's ratio from the response of the stress profile to the isotropic
ambient pressure. In the case of the local incompressibility and quadratic
energy law, a direct relation between the bending modulus and Gaussian
curvature modulus is established
Connection formulae for the radial Toda equations I
This paper is the first in a forthcoming series of works where the authors
study the global asymptotic behavior of the radial solutions of the 2D periodic
Toda equation of type . The principal issue is the connection formulae
between the asymptotic parameters describing the behavior of the general
solution at zero and infinity. To reach this goal we are using a fusion of the
PDE analysis and the Riemann-Hilbert nonlinear steepest descent method of Deift
and Zhou which is applicable to 2D Toda in view of its Lax integrability. A
principal technical challenge is the extension of the nonlinear steepest
descent analysis to Riemann-Hilbert problems of matrix rank greater than .
In this paper, we meet this challenge for the case (the rank case)
and it already captures the principal features of the general case.Comment: 68 pages, 16 figure
Universal geometrical factor of protein conformations as a consequence of energy minimization
The biological activity and functional specificity of proteins depend on
their native three-dimensional structures determined by inter- and
intra-molecular interactions. In this paper, we investigate the geometrical
factor of protein conformation as a consequence of energy minimization in
protein folding. Folding simulations of 10 polypeptides with chain length
ranging from 183 to 548 residues manifest that the dimensionless ratio
(V/(A)) of the van der Waals volume V to the surface area A and average
atomic radius of the folded structures, calculated with atomic radii
setting used in SMMP [Eisenmenger F., et. al., Comput. Phys. Commun., 138
(2001) 192], approach 0.49 quickly during the course of energy minimization. A
large scale analysis of protein structures show that the ratio for real and
well-designed proteins is universal and equal to 0.491\pm0.005. The fractional
composition of hydrophobic and hydrophilic residues does not affect the ratio
substantially. The ratio also holds for intrinsically disordered proteins,
while it ceases to be universal for polypeptides with bad folding properties.Comment: 6 pages, 1 table, 4 figure
