Liberate or Subjugate Them? The Effect of Supplier Dependence on Buyer Innovation
Journal of Product Innovation Management, Volume 43, Issue 4, Page 665-689, July 2026.ABSTRACT This study extends the current understanding of buyer–supplier relationships (BSRs) and innovation by investigating the supplier dependence—buyer innovation relationship. Drawing from resource dependence and exploration‐exploitation perspectives, we hypothesize that supplier dependence negatively affects buyer innovation performance, and that ...

The Effect of Intrinsic Alignments on Weak-lensing Statistics in Hydrodynamical Simulations
The Astrophysical JournalThe next generation of weak-gravitational-lensing surveys has the potential to place stringent constraints on cosmological parameters. However, their analysis is limited by systematics such as the intrinsic alignments of galaxies, which alter weak ...

Observational Test of f(Q) Gravity with Weak Gravitational Lensing
The Astrophysical JournalIn this article we confront a class of f ( Q ) gravity models with observational data of galaxy–galaxy lensing. Specifically, we consider f ( Q ) gravity models containing a small quadratic correction when compared with general relativity (GR), and ...

Alternative estimators for weak gravitational lensing
, 2012 Weak gravitational lensing provides a means to measure the total mass in the Universe. The incoming light from distant galaxies is disturbed by the inhomogeneity of the dark matter distribution along the line of sight. The correlations of shape in an observed galaxy population can be used to probe the total mass density fluctuations in the Universe ...

Weak gravitational lensing with the Square Kilometre Array
, 2015 We investigate the capabilities of various stages of the SKA to perform world-leading weak gravitational lensing surveys. We outline a way forward to develop the tools needed for pursuing weak lensing in the radio band.

Delensing for precision cosmology: optimizing future CMB B-mode surveys to constrain r
European Physical Journal C: Particles and FieldsThe detection of primordial B-modes, a key probe of cosmic inflation, is increasingly challenged by contamination from weak gravitational lensing B-modes induced by large-scale structure (LSS).
