Volume Electron Microscopy of Cortical Organoids: Methods for Region Identification, Connectome Reconstruction, and Organelle Segmentation

Abstract Volume electron microscopy (vEM) has become a powerful tool for 3D ultrastructural analysis of neural circuits, yet its application to human brain organoids remains limited, particularly for connectomic studies. Here, we established a comprehensive and scalable workflow...

Use of Oxygen in the Emergency Department

ABSTRACT Oxygen is one of the most frequently used treatments in the emergency department (ED), but it should be prescribed and reassessed as an active therapy rather than left as a harmless default. Acute hypoxemia may reflect ventilation-perfusion mismatch, shunt, hypoventilati...

Investigating regional electricity consumption across Europe: a spatial analysis

Electricity is increasingly central to Europe's energy transition, but evidence on regional consumption remains limited by the lack of harmonised sub-national data. We address this gap by constructing a regional electricity consumption dataset covering all EU Member States and se...

Viral transport in evaporating sessile model respiratory droplets

Abstract Viral particles, or virions, may remain infectious in the dry residue of respiratory droplets for times as long as hours. This is counterintuitive, since salt concentration increases dramatically as the drop's water evaporates, making the drop a harsh environment for vir...

Fe3O4 Nanopowder under the Effectof Conventional Ultrasonication Treatment

Abstract A new study was conducted to assess the actual effect of ultrasonication, a highly common treatment used to desegregate and deagglomerate nanoparticles for their subsequent dispersion in different media. In particular, Fe3O4 conventional magnetite nanoparticles suspended...

Dielectric waveguide interconnects for hybrid mm-Waves and terahertz system integration

Abstract In this work, we propose interconnection structures for substrateless all-silicon dielectric waveguides, a platform for terahertz (THz) hybrid integration that currently relies on traditional tapered interfaces. We demonstrate two dielectric waveguide-to-waveguide interc...

Transient Cytoskeletal Anisotropy Encodes Short‐Term Mechanical Memory in Glioblastoma Cells

ABSTRACT Cells experience time‐varying mechanical cues when navigating complex microenvironments, yet whether and how they retain a short‐term memory of recent deformations remains unclear. Here, we show that glioblastoma cells encode such memory through transient cytoskeletal an...

User perspectives and scales for collaborative classification tasks in immersive environments

Immersive technologies offer the possibility of facilitating collaboration through new capabilities, like shifting between different scales or perspectives while keeping a first-person view of the workspace. All these features affect collaboration by influencing user behaviour, s...

Symmetry-Resolved Sensitivity Redistribution Under Tensor Lifting in Electromagnetic Sensing Architectures

Symmetric electromagnetic sensing architectures induce representation-space decompositions that organize how measured fields respond to rotations, reflections, and programmable configurations. This paper develops a symmetry-resolved framework for analyzing how local parameter sen...
