Polarization splitter-rotators (PSRs) are the key elements to realize on-chip polarization manipulation. Current PSRs on thin film lithium niobate (TFLN) rely on sub-micron gaps to realize mode separation, which increases the difficulties of lithography and etching. In this paper, a PSR on TFLN based on multimode interference (MMI) is demonstrated.

Background: The above studies indicate that the SCZ animal model has abnormal gamma oscillations and abnormal functional coupling ability of brain regions at the cortical level. However, few researchers have focused on the correlation between brain complexity and connectivity at the cortical level. In order to provide a more accurate representation of brain activity, we studied the complexity of electrocorticogram (ECoG) signals and the information interaction between brain regions in schizophrenic rats, and explored the correlation between brain complexity and connectivity.

The research on high-precision and all-scenario localization using the millimeter-wave (mmWave) band is of great urgency. Due to the characteristics of mmWave, blockages make the localization task more complex. This paper proposes a cooperative localization system among user equipment (UEs) assisted by reconfigurable intelligent surfaces (RISs), which considers device-to-device (D2D) communication.

Article Synopsis
  • Carbon plays a crucial role in how plants and their roots evolve and function, with previous research focusing primarily on a limited number of root traits related to resource economics.
  • This study examines 66 tree species from a tropical forest, finding that root traits vary significantly with molecular-level traits, revealing that thinner roots have more carbohydrates and less molecular carbon diversity compared to thicker roots.
  • The transition from thin to thick fine roots indicates a shift in their function from independent soil exploration to reliance on mycorrhizal fungi, while the change from lighter to denser roots reflects a move from an acquisitive to a conservative root strategy, shedding light on the diversity of root forms and their ecological roles.

Spindle-shaped waves of oscillations emerge in EEG scalp recordings during human and rodent non-REM sleep. The association of these 10-16 Hz oscillations with events during prior wakefulness suggests a role in memory consolidation. Human and rodent depth electrodes in the brain record strong spindles throughout the cortex and hippocampus, with possible origins in the thalamus.
