Image Storage in DNA by an Extensible Quaternary Codec System
Applied SciencesSilicon-based storage technologies are increasingly failing to meet the explosively growing data storage demands of the information age. DNA-based data storage offers a promising solution due to its unparalleled storage density, long lifespan, low energy

Algorithmic counting of nonequivalent compact Huffman codes
, 2019 It is known that the following five counting problems lead to the same integer sequence~$f_t(n)$: the number of nonequivalent compact Huffman codes of length~$n$ over an alphabet of $t$ letters, the number of `nonequivalent' canonical rooted $t$-ary ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.Abstract Model precipitation biases in the intertropical convergence zone (ITCZ) are often tied to the underestimation of stratocumulus (Sc) and shallow cumulus (Cu) clouds. We design a method to distinguish between Sc and Cu cloud regimes under subsidence on daily timescales based on cloud top pressure and vertical velocity to investigate the spatial ...

IET Communications, 2011 In this study, the authors consider the class of anti-uniform Huffman (AUH) codes. The authors derived tight lower and upper bounds on the average codeword length, entropy and redundancy of finite and infinite AUH codes in terms of the alphabet size of the source. These bounds are tighter than similar bounds.

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract This study evaluates the ability of the AI weather forecast model GraphCast to reproduce the global diurnal cycle of boreal summer precipitation, comparing it with Integrated Multi‐satellite Retrievals for GPM (IMERG) satellite observations, the ERA5 reanalysis, and an experimental global 5‐km Met Office Unified Model (UM) which is convection ...

Optimal code design for lossless and near lossless source coding in multiple access networks [PDF]
, 2001 A multiple access source code (MASC) is a source code designed for the following network configuration: a pair of correlated information sequences {Xi}i=1∞ and {Yi }i=1∞ is drawn i.i.d.

An Optimized Parameterization of Sub‐Grid Scale Advection for Convection Permitting Models
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.Abstract Convection‐permitting models (CPMs) explicitly resolve deep convection yet under‐resolve the organized lateral exchanges among drafts and their environment that control entrainment/detrainment, precipitation efficiency, and mesoscale structure.

Parallel data compression [PDF]
, 1991 Data compression schemes remove data redundancy in communicated and stored data and increase the effective capacities of communication and storage devices. Parallel algorithms and implementations for textual data compression are surveyed.

On Regular Quaternary Hadamard Matrices
Journal of Combinatorial Designs, Volume 34, Issue 5, Page 215-227, May 2026.ABSTRACT Through the use of regularizing vectors, all regular quaternary Hadamard matrices of orders 10 and 18 have been successfully identified. Of these, two matrices of order 10 and 184 matrices of order 18 were found to have unbiased mates. Converting the quaternary Hadamard matrices of order 18 to real Hadamard matrices, the study uncovered that ...

Earth and Space Science, Volume 13, Issue 5, May 2026.Abstract Convection‐permitting regional climate models (CP‐RCMs) often outperform coarser‐resolution models in simulating precipitation, but assessing their accuracy across resolutions and configurations remains challenging. This study evaluates the performance and sensitivity of different configurations of the sixth version of the Canadian Regional ...
