Article Synopsis
- Hypervirulent K. pneumoniae (hvKp) is a type of bacteria that can cause serious infections in healthy individuals, characterized by high capsule production and a specific feature known as hypermucoviscosity (hmv).
- Research showed that understanding how capsule production (CPS) and hmv function separately is complicated because they are often seen together and rely on overlapping cellular processes.
- A study analyzed over 3,700 genetic mutants of hvKp, identifying key genes that affect either CPS or hmv, revealing that while hmv needs CPS, both traits can influence pathogenesis distinctly and may depend on specific nutrients for virulence.
We summarize the most recent research of the Georgia Tech Terabit Optical Networking Consortium and the state-of-the-art in fiber telecommunications. These results comprise high-capacity single-mode fiber systems with digital coherent receivers and shorter-reach multimode fiber links with vertical cavity surface emitting lasers. We strongly emphasize the capabilities that sophisticated digital signal processing and electronics add to these fiber-based data transport links.

An accurate motion-tracking technique is needed to compensate for subject motion during functional magnetic resonance imaging (fMRI) procedures. Here, a novel approach to motion metrology is discussed. A structured light pattern specifically coded for digital signal processing is positioned onto a fiduciary of the patient.
