Researchers at Rice University have developed a sophisticated 3D photonic-crystal cavity that can trap and control light in ...

A new study demonstrates how light-dependent resistors (LDRs) and waveguides enable affordable, real-time optical detection ...

There are ten exam-style questions covering topics such as circuit symbols, atomic structure and distance-time graphs. This activity should take approximately 5-10 minutes to complete. There are ...

These questions are suitable for students working on GCSE physics studying any awarding body specification and covers topics from Physics such as circuit symbols, atomic structure, distance-time ...

In this work, a brain-inspired circuit with context-dependent and state-dependent memory is proposed based on the three-level processing model of memory information, which integrates the processes of ...

A minimal end-to-end optical data‑link demonstration using an Arduino’s red LED as transmitter and a light-dependent resistor (LDR) on analog pin A5 as receiver. Text messages sent over serial are ...

This study presents the dynamic causal modeling (DCM) framework to explore the state-dependent effective connectivity using spectral DCM for the resting-state functional MRI (rsfMRI). We established ...
