Optical devices are highly attractive for biosensing as they can not only enable quantitative measurements of analytes but also provide information on molecular structures. Unfortunately, typical refractive index-based optical sensors do have sufficient sensitivity to probe the binding low-molecular-weight analytes. Non-optical such field-effect transistors be more sensitive offer some significant features devices, particularly fingerprinting. We present conductivity-based mid-infrared...

Metasurfaces emerge as a promising photonic platform for biosensing because they offer strong optical confinement and tunable resonances. Here, we show that metasurface-based biosensors consisting of gold nanoantenna arrays loaded with graphene working in the mid-infrared (mid-IR) spectral range can achieve simultaneous high-sensitivity high-specificity detection biomolecules. Strong light–molecule interactions deeply subwavelength spots created by allow us to determine concentration protein...

Scaling Large Language Model (LLM) training relies on multi-dimensional parallelism, where High-Bandwidth Domains (HBDs) are critical for communication-intensive parallelism like Tensor Parallelism (TP) and Expert (EP). However, existing HBD architectures face fundamental limitations in scalability, cost, fault resiliency: switch-centric HBDs (e.g., NVL-72) incur prohibitive scaling costs, while GPU-centric TPUv3/Dojo) suffer from severe propagation. Switch-GPU hybrid such as TPUv4 takes a...
