Exploring the effects of feeding emotional stimuli to large language models
Since the advent of OpenAI's ChatGPT, large language models (LLMs) have become significantly popular. These models, trained on vast amounts of data, can answer written user queries in strikingly human-like ways, rapidly generating definitions to specific terms, text...
Study explores the impact of climate change on the supply and demand of wind and solar energy
Over the past few decades, sustainable energy solutions that rely on renewable sources, particularly the sun and wind, have become increasingly advanced and widespread. Many countries worldwide have committed to drastically lowering carbon emissions in the next decade...
New transparent metadevices based on quasi-1D surface plasmon polariton structures
Transparent electronic devices could have numerous valuable real-world applications. Among other things, they could enable the creation of new optical devices, smart gear or wearables, invisible solar panels and integrated communication systems.
A CMOS-compatible spintronic compute-in-memory macro to secure AI edge devices
Edge computing applications, which entail the processing and storage of data at the source of its production (i.e., near where it is created), is now being applied to a growing number of technologies. The application of edge computing translates into devices that can...
An approach to enhancing relaxors for energy storage devices
Relaxor ferroelectrics are materials with ferroelectric properties and high electrostriction (i.e., the ability to contract or deform in response to electric fields). These materials can be used to create highly efficient energy storage devices, such as capacitors.
A polyamide-based soft jellyfish robot actuated by a shape memory alloy
In recent decades, roboticists have been developing increasingly sophisticated robots inspired by nature and living organisms. By realistically emulating biological processes and animal behaviors, these robots can often navigate different environments and tackle...
