Bounded Sustainable Entrepreneurship: Uncertainty, Perceptions, and Tensions

open access: yesStrategic Change, EarlyView.
ABSTRACT Entrepreneurs experience subjective perceptions of uncertainty and other barriers as they attempt to design their business model. These create boundaries of a cognitive nature that entrepreneurs must navigate. It has been suggested that sustainable entrepreneurship is inherently even more uncertain and complex than traditional entrepreneurship.

Is acidification of common estuarine macroinvertebrates in stable isotope approaches necessary to analyze aquatic food webs?

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract We evaluated the effect of in situ acidification of common estuarine macroinvertebrates from the Elbe estuary on stable isotope ratios, as the non‐removal of non‐dietary carbon can significantly influence aquatic food web analyses. A 10% HCl solution was used to remove inorganic carbon from crustaceans, which potentially biases the true ratio ...

High‐Speed Multimode Fiber Imaging Using Binary‐Modulated Silicon Photonics Optical Phased Array

open access: yesLaser &Photonics Reviews, EarlyView.
A multimode fiber imaging system at 500 frames per second is experimentally demonstrated. It is enabled by a p‐i‐n diode‐based silicon photonics optical phased array. To simplify the electrical driving of p‐i‐n diodes, a binary modulation method with a costumed‐designed digital driver circuit is proposed. Reconstruction of each frame takes only 0.1 ms,

Recent Advances in Injectable Hydrogel Biotherapeutics for Regenerative Dental Medicine

open access: yesMacromolecular Bioscience, EarlyView.
This review analyses multifunctional injectable hydrogels, natural or synthetic, physically or chemically crosslinked, that deliver exosomes, stem cells, and other bioactive cues to inflamed or damaged oral tissues. We discuss their immunomodulatory, antimicrobial, angiogenic, and osteogenic capacities, highlighting advances that enable regenerative ...
