The optimal method for three-dimensional thermal imaging within cells involves collecting intracellular temperature responses while simultaneously obtaining corresponding 3D positional information. Current temperature measurement techniques based on the photothermal properties of quantum dots face several limitations, including high cytotoxicity and low fluorescence quantum yields. These issues affect the normal metabolic processes of tumor cells.

Article Synopsis
  • Mode-division multiplexing (MDM) and wavelength-division multiplexing (WDM) are effective methods to increase the capacity of fiber-optic systems, requiring amplification techniques like distributed Raman amplifiers (DRA) for signal light enhancement.
  • This study showcases the successful transmission of 3 OAM modes and 9 WDM channels over a 104-km custom ring-core fiber using DRA to amplify the signals.
  • The developed mode selective couplers efficiently (de)multiplex OAM modes, while the OAM-DRA achieves high and flat gain, crucial for maintaining performance over long distances in the communication spectrum.

The finite resource of land is subject to competing pressures from food demand, urbanization, and ecosystem service provision. Linking the land resource use to the whole production chain and final consumption of various products and services offers a new perspective to understand and manage land uses. This study conducted a systematic analysis of land uses at the provincial level in China using the multi-region input-output model in 2012.
