Small Methods, EarlyView.Dilution‐controlled AF4 coupled with SAXS and, for the first time, SANS enables high‐resolution characterization of non‐spherical lipid nanoparticles. Enhanced scattering contrast and D2O‐based measurements resolve particle features down to ∼5 nm and reveal shape distributions.

High Voltage, EarlyView.ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

PARTY‐STATE URBANISM: Coevolution of Local State Capacity and Strategic Alliances in Shenzhen
International Journal of Urban and Regional Research, EarlyView.Abstract What is distinct about Chinese urban governance? Classic theories predict that when the central state retreats from resource allocation, capacity‐strained local governments must form alliances with non‐state actors, thereby diluting state power. In China, however, state power remains dominant despite decentralization.

Adaptation of thoracic and lumbar curvature and spinal muscle activity under changing gravity
Frontiers in PhysiologyIntroductionThe effect of micro-gravity on the lumbar and in particular thoracic regions is poorly understood. The aim of this study was to evaluate spinal curvature across the lumbar and thoracic region, and extensor muscle activity during acute micro ...

Anatomical and functional brain approach along short abrupt changes in G-levels [PDF]
, 2016 To conduct experiments under abrupt changes in g-levels, a single-engine aerobatic aircraft has been used, providing 6-8 seconds of reduced gravity, preceded and followed by 5-7 seconds of hypergravity periods.

Enchanting the Otherwise: Magical Realism and the Gendered Ontologies of Organizational Becoming
Gender, Work &Organization, EarlyView.ABSTRACT This paper enacts a feminist‐posthumanist reimagining of gender as ontological disturbance, using magical realism not as metaphor but as epistemological method. Rejecting representational logics and the managerial rationalities of organizational realism, we advance gender not as identity or role but as spectral interference—a transversal ...
