Scientists developed a new way of investing in stocks using natural language processing. Using dynamic topic modeling, a variant of Latent Dirichlet Allocation, the new model uncovers hidden risk factors directly from company reports and translates them into tradable indices with minimal human oversight. Investors can now trade these risk factors directly and track industry trends using only the information contained in words.

Researchers at the Korea Research Institute of Chemical Technology (KRICT), led by Dr. Chi Hoon Park, have successfully generated CAR-M (Chimeric Antigen Receptor Macrophages) by stably inserting synthetic genes into human macrophages derived from peripheral blood using a lentiviral delivery system.

Traditional terahertz (THz) polarization conversion devices show the unchanged polarization state on each output plane along the propagation path. This paper proposes a THz polarization controlled metasurface device that is dependent on propagation distance, which can continuously modify the polarization state of each output plane along the propagation path. The designed metasurface device can control the phase difference between the left-handed and right-handed circularly polarized components in the incident THz linearly polarized wave. This phase difference changes with the propagation distance, and ultimately outputs a linearly polarized wave that rotates along the propagation path. The polarization rotation angle can cover 0 to π. This device may have potential applications in fields such as variable matter excitation, THz communication, THz radar, THz sensing.

This work developed a new deep learning framework, MULGONET, to predict cancer recurrence and identify key biomarkers by integrating multi omics data (such as mRNA, DNA methylation, copy number variation). By utilizing the gene ontology (go) hierarchy, the model overcomes the challenges of data dimensionality and interpretability, and achieves higher accuracy in bladder cancer, pancreatic cancer, and gastric cancer datasets. This innovation enables clinicians to pinpoint key genes and biological pathways associated with cancer recurrence, paving the way for personalized treatment strategies.

Researchers create for the first time volumetric graphics in mid-air that can be directly grabbed and manipulated with the hands. We are used to direct interaction with our phones, where we tap a button or drag a document directly with our finger on the screen – it is natural and intuitive for humans. This technology enables us to use this natural interaction with 3D graphics to leverage our innate abilities of 3D vision and manipulation.
