Article Synopsis
- This study used advanced technology to analyze how different treatments affect the texture of ready-to-eat (RTE) shrimps during storage.
- The ultra-high pressure heat-assisted treatment (UHP-HAT) improved shrimp texture while also reducing damage from protein oxidation.
- A predictive model was created using hyperspectral imaging, showing a strong link between texture and spectral data, helping to reveal the chemical changes in the shrimp's protein structure.

Machine perception uses advanced sensors to collect information about the surrounding scene for situational awareness. State-of-the-art machine perception using active sonar, radar and LiDAR to enhance camera vision faces difficulties when the number of intelligent agents scales up. Exploiting omnipresent heat signal could be a new frontier for scalable perception.

Cells assemble macromolecular complexes into scaffoldings that serve as substrates for catalytic processes. Years of molecular neurobiology research indicate that neurotransmission depends on such optimization strategies. However, the molecular topography of the presynaptic active zone (AZ), where transmitter is released upon synaptic vesicle (SV) fusion, remains to be visualized.

A theory is presented to describe the heat flux radiated in the near-field regime by a set of interacting nanoemitters held at different temperatures in vacuum or above a solid surface. We show that this thermal energy can be focused and even amplified in spots that are much smaller than those obtained with a single thermal source. We also demonstrate the possibility to locally pump heat using specific geometrical configurations.
