Leader Succession and Strategic Change: The Role of Leader's Subgroups Size

Strategic Change, Volume 35, Issue 4, Page 725-741, July 2026.
ABSTRACT Research suggests that new CEO successors drive strategic change through the subgroup of their immediate collaborators. However, it remains unclear how this subgroup is configured. In this research, we address this limitation by introducing a new concept of “CEO's subgroup size” (the number of TMT members in the CEO's subgroup).

Postnatal characterization of cells in the accessory olfactory bulb of wild type and reeler mice

Frontiers in Neuroanatomy, 2012
Olfaction is the most relevant chemosensory sense of the rodents. General odors are primarily detected by the main olfactory system while most pheromonal signals are received by the accessory olfactory system.

Beyond Surface Area: The Role of Carrier Media Structure on Nitrification Performance and Biomass Activity in MBBR Systems Under High Nitrogen Loads

Water Environment Research, Volume 98, Issue 7, July 2026.
Carrier structural configuration, rather than nominal surface area alone, influenced nitrification performance in long‐term autotrophic MBBRs operated under high nitrogen loads. Non‐porous media promoted greater biofilm accumulation and more stable ammonium removal, suggesting that biomass retention capacity plays an important role in sustaining ...

Chemical Speciation Defines Archaeal Ammonia‐Oxidizer Distribution in Yellowstone Hot Springs

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract The hot springs of Yellowstone National Park (YNP) provide a natural laboratory for investigating the influence of chemical speciation and energy availability on the distribution of microbes. Among 133 inorganic chemotrophic energy supplies, total dissolved ammonia oxidation was consistently one of the highest across 63 YNP hot spring samples.

NITRIFICATION AND NITRIFYING BACTERIA IN A COASTAL MICROBIAL MAT

Frontiers in Microbiology, 2015
The first step of nitrification, the oxidation of ammonia to nitrite, can be performed by ammonia-oxidizing archaea (AOA) or ammonium-oxidizing bacteria (AOB).

Diversity, abundance and niche differentiation of ammonia-oxidizing prokaryotes in mud deposits of the eastern China marginal seas

Frontiers in Microbiology, 2016
The eastern China marginal seas are prominent examples of river-dominated ocean margins, whose most characteristic feature is the existence of isolated mud patches on sandy sediments.

Migrating Bitcoin to AOB for Enhanced Security

Despite Bitcoin's success, its Proof-of-Work (PoW) consensus mechanism has inherent security vulnerabilities, as highlighted by a recent 51% attack on Monero in 2025. This paper proposes a solution: migrating Bitcoin to the Atomic Ownership Blockchains (AOB) framework.
