We describe the details of an optical communication system using Gaussian vortex beams (GVBs). Our main focus will be on the detection strategy. The transmitter encodes the message symbols into the topological charges of the GVBs. Then the receiver implements a detection strategy based on the orthogonality of the GVBs. The graphical results obtained from the related theoretical derivation indicate that this detection strategy has almost no bounds. Thus, it is concluded that the performance of such a system can only be practically limited.

Background: Recent studies indicate that N6-methyladenosine (mA) RNA modification may regulate ferroptosis in cancer cells, while its molecular mechanisms require further investigation.
Methods: Liquid Chromatography-Tandem Mass Spectrometry (HPLC/MS/MS) was used to detect changes in mA levels in cells. Transmission electron microscopy and flow cytometry were used to detect mitochondrial reactive oxygen species (ROS).

Background: Pathogenic bacteria are widespread in nature and can cause infections and various complications, thereby posing a severe risk to public health. Therefore, simple, rapid, sensitive, and cost-effective methods must be developed to detect pathogenic bacteria. Biosensors are prominent platforms for detecting pathogenic bacteria owing to their high sensitivity, specificity, repeatability, and stability.
