Handle with care: Power and perils of compound semiconductors
In the realm of advanced electronics and photonics, compound semiconductors are the silent enablers of breakthrough performance in many applications. Built from materials like indium gallium arsenide (InGaAs) or gallium arsenide (GaAs), these semiconductors enable applications that are beyond the capabilities of silicon devices. Examples include avalanche photodiodes (APDs) for ultra-sensitive infrared detection at eye-safe…
Study shows vision-language models can’t handle queries with negation words
Imagine a radiologist examining a chest X-ray from a new patient. She notices the patient has swelling in the tissue but does not have an enlarged heart. Looking to speed up diagnosis, she might use a vision-language machine-learning model to search for reports from similar patients. But if the model mistakenly identifies reports with both…
