Staying Offline or Going Online? Managing the Establishment of Service Platforms

open access: yesManagerial and Decision Economics, EarlyView.
ABSTRACT We study a global game in which consumers and sellers decide whether to join a service platform and interact more efficiently online. Uncertainties about the platform's technology value and users' participation behavior on both market sides cause a coordination problem.

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

open access: yesNordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Protein Acetylation Mediated by YfiQ and CobB Is Involved in the Virulence and Stress Response of Yersinia pestis

open access: yesInfection and Immunity, 2018
Recent studies revealed that acetylation is a widely used protein modification in prokaryotic organisms. The major protein acetylation acetyltransferase YfiQ and the sirtuin-like deacetylase CobB have been found to be involved in basic physiological ...

Anatomy of production functions: a technological menu and a choice of the best technology [PDF]

open access: yes
Jones (2005) proposed microfoundations for the Cobb-Douglas production function. We show that Jones' technological menu is a special case of a concept of support set discussed by Matveenko (1997) and Rubinov, Glover (1998) by use of a duality approach ...

Shifts in phenology influence synchrony of flowering plants and their pollinators along an elevation gradient

open access: yesOikos, EarlyView.
Climatic conditions alter the phenology of species, which may threaten the synchrony of biotic interactions. However, how phenological synchrony across entire communities of plants and their pollinators responds to varying environmental conditions remains poorly understood.

Cobb-Douglas Production Function: The Case of a Converging Economy [PDF]

open access: yes
The Cobb-Douglas production function is often used to analyse the supply-side performance and measurement of a country’s productive potential. This functional form, however, includes the assumption of a constant share of labor in output, which may be too

Hydrogen Permeation in Polyethylene: Effect of Crystallinity on Gas Transport Coefficients at Different Temperatures

open access: yesJournal of Polymer Science, EarlyView.
Correlation of H2 permeability in semicrystalline polymers used as liners in Type IV composite tanks, versus temperature and crystallinity. ABSTRACT Semicrystalline polymers such as high‐density polyethylene (HDPE) are increasingly adopted as liners in compressed hydrogen storage tanks, due to low weight, easy processing, and high durability, together ...

Application of two-parameter scoliometer values for predicting scoliotic Cobb angle

open access: yesBioMedical Engineering OnLine, 2017
BackgroundAdolescent idiopathic scoliosis, in which obvious curves are visible in radiographic images, is also seen in combination with lumps in the back. These lumps contribute to inclination, which can be measured by a scoliometer.

The Cobb-Gouglas function as an approximation of other functions [PDF]

open access: yes
By defining the Variable Output Elasticities Cobb-Douglas function, this article shows that a large class of production functions can be approximated by a Cobb-Douglas function with nonconstant output elasticity.
