Eliciting Latent Predictions from Transformers with the Tuned Lens [PDF]
arXiv.org, 2023 We analyze transformers from the perspective of iterative inference, seeking to understand how model predictions are refined layer by layer. To do so, we train an affine probe for each block in a frozen pretrained model, making it possible to decode ...

Negative refraction makes a perfect lens [PDF]
Physical Review Letters, 2000 With a conventional lens sharpness of the image is always limited by the wavelength of light. An unconventional alternative to a lens, a slab of negative refractive index material, has the power to focus all Fourier components of a 2D image, even those ...

Principles, Functions, and Applications of Optical Meta‐Lens
Advanced Optical Materials, 2021 A meta‐lens is an advanced flat optical device composed of artificial antennas. The amplitude, phase, and polarization of incident light can be engineered to satisfy the application requirements of meta‐lenses.

CLEAR - Contact lens complications.
Contact lens & anterior eye : the journal of the British Contact Lens Association, 2021 Contact lens-related complications are common, affecting around one third of wearers, although most are mild and easily managed. Contact lenses have well-defined anatomical and physiological effects on the ocular surface and can result in other ...

Wireless smart contact lens for diabetic diagnosis and therapy
Science Advances, 2020 We demonstrate smart contact lenses for noninvasive and continuous diabetic diagnosis and diabetic retinopathy therapy. A smart contact lens can be used as an excellent interface between the human body and an electronic device for wearable healthcare ...

MEMS-tunable dielectric metasurface lens [PDF]
Nature Communications, 2017 Varifocal lenses, conventionally implemented by changing the axial distance between multiple optical elements, have a wide range of applications in imaging and optical beam scanning. The use of conventional bulky refractive elements makes these varifocal

ADVANCED OPTICAL TECHNIQUES TO EXPLORE BRAIN STRUCTURE AND FUNCTION [PDF]
Journal of Innovative Optical Health Sciences, 2013 Understanding brain structure and function, and the complex relationships between them, is one of the grand challenges of contemporary sciences. Thanks to their flexibility, optical techniques could be the key to explore this complex network.

CLEAR - Contact lens technologies of the future.
Contact lens & anterior eye : the journal of the British Contact Lens Association, 2021 Contact lenses in the future will likely have functions other than correction of refractive error. Lenses designed to control the development of myopia are already commercially available.

Nature Communications, 2022 By using laser tweezers, the authors show that a single α-catenin molecule does not resist force on F-actin. However, clustering of multiple molecules and force applied toward F-actin pointed end engage a molecular switch in α-catenin, which unfolds and ...
