Exploring the knowledge spillovers of a technology in an entrepreneurial ecosystem—The case of artificial intelligence in Sydney

Dilek Cetindamar, Thorsten Lammers, Yi Zhang

Thunderbird International Business Review > 62 > 5 > 457 - 474

New knowledge presents opportunities for commercial value and can hence be a critical asset for entrepreneurial ecosystems (EEs). In particular, general purpose technologies are major drivers of entrepreneurship. Thus, a nuanced understanding on technological knowledge and its spillovers among actors within an EE is warranted. Using knowledge‐spillover‐based strategic entrepreneurship theory, we propose...

General soliton solutions to a reverse‐time nonlocal nonlinear Schrödinger equation

Rusuo Ye, Yi Zhang

Studies in Applied Mathematics > 145 > 2 > 197 - 216

General soliton solutions to a reverse‐time nonlocal nonlinear Schrödinger (NLS) equation are discussed via a matrix version of binary Darboux transformation. With this technique, searching for solutions of the Lax pair is transferred to find vector solutions of the associated linear differential equation system. From vanishing and nonvanishing seed solutions, general vector solutions of such linear...

Xiaomin Huang, Zhenwei Song, Kees Jan Groenigen, Zhiyu Xu, more

Soil Use and Management > 36 > 3 > 410 - 419

Soil organic carbon (SOC) stocks and nutrient availability are key indicators of soil quality, and both can be influenced by land‐use change. However, it is still unclear whether the impact of land‐use change on SOC and nutrient stocks differs between ecoregions. Grasslands near the northeast border of the Qinghai‐Tibetan Plateau (QTP) occur across several ecoregions that have recently been subjected...

Zhonghai Li, Jin Hee Kim, Jeongsik Kim, Jae Il Lyu, more

New Phytologist > 227 > 2 > 473 - 484

All living organisms are unavoidably exposed to various endogenous and environmental stresses that trigger potentially fatal DNA damage, including double‐strand breaks (DSBs). Although a growing body of evidence indicates that DNA damage is one of the prime drivers of aging in animals, little is known regarding the importance of DNA damage and its repair on lifespan control in plants. We found...
