Interactive Extended Reality Worlds with JSON Data Generated by Large Language Models
Recent LLM-XR systems mostly drive experiences by generating and compiling code on the fly. In complex scenes with thousands of artifacts and properties, models struggle to pick the right context, inflating token usage and still missing crucial constraints—like keeping cups on tables. Hallucinated or malformed scripts often fail to compile or...

DNA/RNA Origami Assembly Mediated by Functional Peptides
DNA and RNA nanostructures, e.g., DNA Origami, have great potential in biological applications, including extracellular matrix scaffolds and delivery vehicles for drugs and gene therapies. While folding DNA origami under physiological conditions is plausible, significant challenges and limitations remain. For example, isothermal annealing of DNA origami...

DNA Methylation Barriers
In normal differentiated cells, most of the genome is densely methylated, except CpG islands near promoters of actively transcribed genes. Maintaining this boundary between unmethylated promoter-associated and adjacent methylated regions is crucial as loss of segregation can lead to disease. Unfortunately, it is not clear where these boundaries are,...

Ultra-sensitive Diagnostic Detects fg/mL-pg/mL Pathogen/Disease Protein by Visual Color Change
This technology is an ultra-sensitive colorimetric assay, based on an enzyme-catalyzed gold nanoparticle growth process, for detection of disease-associated proteins (biomarkers) and disease diagnosis. Current detection methods, such as ELISA immunoassays, measure concentrations above 0.1 ng/mL in a sample. PCR, although more sensitive than ELISA, requires...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids
The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

Functionalized Porous Polymer Nanocomposites via Introducing Functional Components into Emulsion Systems
AbstractFunctional porous polymer films are of great interest to academia as well as industry for a variety of applications, such as gas separation, water purification and sensors. A porous structure can not only reduce the density of the material, but can also remarkably increase the surface/interface area, which can be used for various functionalizations....

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers
Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...

Two-terminal multicolor photo-detectors (PD) and focal plane arrays (FPA)
The state of the art of two-color focal plane arrays (FPAs) are two or three terminal photo detector pixels integrated with electronic readout circuits (ROICs). However, a multicolor (> 2) photodetector pixel requires many more terminals, making it very difficult, if not impossible, to integrate multicolor pixel arrays to ROICs due to the increase...
