A Review of Classical Lossless Data Compression Algorithmsand Their Contemporary Relevance [PDF]
Biuletyn Wojskowej Akademii TechnicznejCompression is data processing aimed at reducing the amount of information (e.g., for archiving and transfer). There is lossyand lossless compression. Compression algorithms can be either general-purpose or designed for specific types of data (e.g., for ...

Magnetically Reconfigurable Mode Strong Coupling Toward Tunable Nanophotonic Sensing Devices
Nanophotonics, Volume 15, Issue 12, 25 June 2026.A magnetically reconfigurable metasurface realizes tunable strong coupling between structural and magneto‐structurally induced q‐BIC resonances without changing device geometry. The resulting hybrid branches enable high‐sensitivity refractive‐index sensing with noncontact active control, large figure of merit, and multiple resonance observables ...

A new lossless image compression algorithm based on arithmetic coding
, 1997 We present a new lossless image compression algorithm based on Arithmetic Coding. Our algorithm selects appropriately, for each pixel position, one of a large number of possible, dynamic, probability distributions, and encodes the current pixel ...

Tunable Plasmon‐Enhanced Wide‐Angle Terahertz Perfect Absorption via Lorentz Media
Nanophotonics, Volume 15, Issue 11, 13 June 2026.A planar graphene‐Lorentz‐DBR structure realizes wide‐angle terahertz perfect absorption through a composite phase‐amplitude matching mechanism. The Lorentz dielectric provides dispersive phase compensation and controlled loss, whereas graphene supports dissipative coupling, enabling high absorption up to 80° incidence and multichannel spectral ...

Perceptually lossless image compression [PDF]
, 1997 journal articleThis paper presents an algorithm for perceptually lossless image compression. A compressed image is said to be perceptually lossless for a specified viewing distance if the reconstructed image and the original image appear identical to ...

Light‐Induced Entropy for Secure Vision
Advanced Materials, Volume 38, Issue 33, 12 June 2026.This work realized a ternary true random number generator by exploiting stochastic traps emerging within multiple junction interfaces, and quantitatively validated the generation of high‐quality random numbers. Furthermore, it successfully demonstrated diverse applications, including AI‐resilient image security, thereby providing a valuable guide for ...
