A recent study finds that hope appears to be more beneficial than mindfulness at helping people manage stress and stay professionally engaged during periods of prolonged stress at work. The study underscores the importance of looking ahead, rather than living “in the moment,” during hard times.
An electro-optic duplex memristor on a GaN/AlScN hetero-structure based Schottky diode has been realized. This two-terminal memristor shows good electrical and opto-electrical nonvolatility and reconfigurability.
Surprising details about mosquito mating could lead to improved malaria control techniques and help develop precision drone flight. A paper published Aug. 30 in Current Biology revealed that when a male Anopheles coluzzii mosquito hears the sound of female-specific wingbeats, his eyes “activate” and he visually scans the immediate vicinity for a potential mate.
Broadband electroluminescence based on environment-friendly emitters is promising for healthy lighting yet remains an unprecedented challenge to progress.
Realizing the multiplexed manipulation of orbital angular momentum (OAM) and other degree of freedoms (DoFs) of photons in subwavelength scale is a highly desired goal in fields of photonics, integrated optics, and optical engineering.
Superconducting memlogic sensors merge in-cell logic and memory, advancing machine vision beyond traditional computing. These sensors utilize the quantum-sensitive and broad-spectrum capabilities of superconductors. We introduce a long-wave infrared sensor using superconductor-normal phase bistability, enabling deterministic, persistent switching.
Mid-infrared (MIR) temporal ghost imaging allows for reconstructing fast temporal objects using a commercially available MIR slow photodetector. To toward this goal, Scientists in China conceived a frequency downconversion temporal ghost imaging scheme that enables us to realize computational temporal ghost imaging in the mid-infrared.
In 1948, Dennis Gabor proposed the concept of holography. After 75 years of development, holographic imaging has become a powerful tool for optical wavefront measurement, which has given fresh energy to physics, biology, and materials science. Scientists in China regard the process of holographic recording and reconstruction as a transformation between complex-domain and real-domain, and discuss the mathematics and physical principles of reconstruction. The multidisciplinary nature brings it to label-free biology, wavefront sensing, and semiconductor production.
Dispersive devices and broadband laser sources are central building blocks for modern optical communication and processing systems. Urgent and demanding requirements have been placed today on spectrum analysis of these devices, for ever-increasing spectral bandwidth and frequency resolution. Current spectrometers have limitations to address these requirements.
