Photon Avalanching Nanoparticles: The Next Generation of Upconverting Nanomaterials?

Advanced Functional Materials, EarlyView.
This Perspective outlines the mechanistic foundations that enable photon‐avalanche (PA) behavior in lanthanide nanomaterials and contrasts them with emerging application spaces and forward‐looking design strategies. By bridging threshold engineering, energy‐transfer dynamics, and materials engineering, we provide a coherent roadmap for advancing the ...

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

Advanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

Aberrant birds: five cases of progressive graying in southern brazil

Acta Zoológica Lilloana
The plumage of birds can exhibit various chromatic aberrations, with progressive graying being one example. This condition is characterized by the presence of randomly scattered white feathers, giving the bird a mottled appearance.

An extended d(min) = 4 RS code [PDF]

A minimum distance d sub m - 4 extended Reed - Solomon (RS) code over GF (2 to the b power) was constructed. This code is used to correct any single byte error and simultaneously detect any double byte error. Features of the code; including fast encoding

Suboptimal soft-decision decoding for some RS-codes

Electronics Letters, 1998
A novel soft-decision algorithm is presented for Reed-Solomon (RS) codes, based on the reordering of the symbols of the received word according to some measure of reliability. The simulation results show that improvements in coding gain of > 1 dB are possible when compared to similar decoding algorithms using unsorted received words.

Dispensing Volumetric Additive Manufacturing

Advanced Functional Materials, EarlyView.
Dispensing volumetric additive manufacturing (DVAM) prints 3D structures inside a photocurable resin droplet suspended from the tip of a glass pipette, enabling sequential printing without resin vats or manual part removal. Real‐time droplet profiling and ray‐tracing‐based correction compensate for optical distortion at the curved resin‐air interface ...

An Application of Polynomial on RS Codes

Journal of Research in Applied Mathematics
In this paper we discuss a class of codes called RS Codes are subset of BCH Code and linear block codes can be constructed to be multiple error-correcting. We use application of polynomial on RS Codes and apply them using Maple.
