Strategic Agility—An Urgent Capability for Successful Business Model Innovation? A Conceptual Process Model and Theoretical Framework

open access: yesStrategic Change, EarlyView.
ABSTRACT Strategic agility (SA) has become an essential capability for established firms to successfully navigate the challenges of business model innovation (BMI) in dynamic environments. This study develops both a conceptual process model and a theoretical framework to explore the interplay between SA and BMI.

Time and phase alignment of distributed gateways: Theoretical analysis and experimental demonstration

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView., 2023
The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.

Enhancing Atmospheric Turbulence Phase Screen Generation with an Improved Diffusion Model and U-Net Noise Generation Network

open access: yesPhotonics
Simulating atmospheric turbulence phase screens is essential for optical system research and turbulence compensation. Traditional methods, such as multi-harmonic power spectrum inversion and Zernike polynomial fitting, often suffer from sampling errors ...

Mountain waves in a turbulent atmosphere

open access: yesTellus A: Dynamic Meteorology and Oceanography, 1971
The propagation of mountain waves in an atmosphere with a fluctuating parameter of stability is studied. Two cases are considered, the Gaussian, and a discontinuous Markov chain, corresponding to a dry and a wet atmosphere, respectively.DOI: 10.1111/j.2153-3490.1971.tb00551 ...

Nutrient enrichment—but not warming—increases nitrous oxide emissions from shallow lake mesocosms

open access: yesLimnology and Oceanography, EarlyView.
Abstract Shallow lakes and ponds play a crucial role in the processing of carbon and other nutrients. However, many lakes and ponds worldwide are affected by climate change and nutrient pollution. How these pressures affect the emission of the greenhouse gas nitrous oxide (N2O) is unclear.
