AI Article Synopsis
- Nonlinear mode coupling occurs in birefringent optical fibers when two beams of different wavelengths travel together.
- This coupling can result in a phenomenon called modal attraction, where the modes of light influence each other.
- As a result, the pattern of light from the pump beam can be observed at the signal beam's wavelength, regardless of how the signal beam is initially set up.
Article Abstract
Nonlinear mode coupling among two beams of different wavelength that copropagate in a bimodal highly birefringent optical fiber may lead to the effect of modal attraction. Under such circumstances, the modal distribution of light at a pump wavelength is replicated at the signal wavelength, nearly irrespective of the input mode excitation conditions of the signal.

Raman spectroscopy, a nondestructive optical technique that provides detailed chemical information, has attracted growing interest in the food industry. Complementary spectroscopic methods, such as near-infrared (NIR) spectroscopy, nuclear magnetic resonance (NMR), terahertz (THz) spectroscopy, laser-induced breakdown spectroscopy (LIBS), and fluorescence spectroscopy (Flu), enhance Raman spectroscopy's capabilities in various applications. The integration of Raman with these techniques, termed "Raman plus X," has shown significant potential in agri-food analysis.

Sensory compensation occurs when loss of one sense leads to enhanced perception by another sense. We have identified a previously undescribed mechanism of sensory compensation in female mosquitoes. Odorant receptor co-receptor () mutants show enhanced attraction to human skin temperature and increased heat-evoked neuronal activity in foreleg sensory neurons.

In a dynamic visual search environment, a synchronous and meaningless auditory signal (pip) that corresponds with a change in a visual target promotes the efficiency of visual search (pop out), which is known as the pip-and-pop effect. We conducted three experiments to investigate the mechanism of the pip-and-pop effect. Using the eye movement technique, we manipulated the interval rhythm (Exp.

The oncogenic Epstein-Barr virus (EBV) can drive tumorigenesis with disrupted host immunity, causing malignancies including post-transplant lymphoproliferative disorders (PTLDs). PTLD can also arise in the absence of EBV, but the biological differences underlying EBV(+) and EBV(-) B cell PTLD and the associated host-EBV-tumor interactions remain poorly understood. Here, we reveal the core differences between EBV(+) and EBV(-) PTLD, characterized by increased expression of genes related to immune processes or DNA interactions, respectively, and the augmented ability of EBV(+) PTLD B cells to modulate the tumor microenvironment through elaboration of monocyte-attracting cytokines/chemokines.
