Trouble in Paradise? Barriers to Open Innovation in Regional Clusters in the Era of the 4th Industrial Revolution

Journal of Open Innovation: Technology, Market and Complexity, 2020
The purpose of this paper is to provide an insight into the barriers faced by clusters as open innovation intermediaries. Literature review and an empirical study were performed, involving a nation-wide survey, case studies, and in-depth interviews with ...

Basic Kinematics of the Galactic Disk from Open Cluster Data

Open Astronomy, 2016
The kinematic parameters of the Galactic disk are redetermined based on open-cluster data. It is shown that the Bottlinger-Oort model of pure circular rotation can be confidently used to describe the observed motions of disk objects at least out to ...

Stellar Variability toward the Galactic Open Cluster NGC 7209

The Astrophysical Journal
We present the analysis of stellar variability in an open cluster NGC 7209 using optical V -band CCD photometric observations. Out of 4499 stars in our study, we detected 284 candidate variables, including one identified previously.

The orbit of the old, metal-rich, open cluster NGC 6791

EPJ Web of Conferences, 2012
We present a study of the Galactic orbit of the old, metal-rich open cluster NGC 6791. To recover its recent kinematical history we integrate the cluster’s orbit backward in a Milky Way (MW) model including bar and spiral structure.

β,β-Isomer of Open-Wells–Dawson Polyoxometalate Containing a Tetra-Iron(III) Hydroxide Cluster: [{Fe4(H2O)(OH)5}(β,β-Si2W18O66)]9−

Inorganics, 2016
The β,β-isomer of open-Wells–Dawson polyoxometalate (POM) containing a tetra-iron(III) cluster, K9[{Fe4(H2O)(OH)5}(β,β-Si2W18O66)]·17H2O (potassium salt of β,β-Fe4-open), was synthesized by reacting Na9H[A-β-SiW9O34]·23H2O with FeCl3·6H2O at pH 3, and ...

Vilnius Multicolor CCD Photometry of the Open Cluster NGC 752

Open Astronomy, 2011
We have performed multicolor CCD observations of the central area of NGC 752 to search for faint, low-mass members of this open cluster. Four 12’ x 12’ fields were taken on the 1.8 m Vatican Advanced Technology Telescope (Mt.

The expression of the primigenic dominance in the flowering and fruit set of selected apple cultivars on different growth inducing rootstocks

International Journal of Horticultural Science, 2008
Authors investigated the expression of the primigenic dominance in the flowering and fruit from open and self pollination of four apple cultivars ('Gala Royal', 'Golden Smoothee', Pink Lady' and 'Vista Bella') during two consecutive years in Western ...

A preliminary comparison of photometric (MWSC) and trigonometric (TGAS) distances of open cluster stars

Open Astronomy, 2017
The goal of this researchwas to compare the open cluster photometric distance scale of the global survey of star clusters in the MilkyWay (MWSC) with the distances derived fromtrigonometric parallaxes fromthe Gaia DR1/TGAS catalogue and to investigate ...
