Subspace Polynomials and Cyclic Subspace Codes

, 2015
Subspace codes have received an increasing interest recently due to their application in error-correction for random network coding. In particular, cyclic subspace codes are possible candidates for large codes with efficient encoding and decoding ...

Cyclic LRC codes, binary LRC codes, and upper bounds on the distance of cyclic codes [PDF]

International Journal of Information and Coding Theory, 2016
We consider linear cyclic codes with the locality property, or locally recoverable codes (LRC codes). A family of LRC codes that generalize the classical construction of Reed-Solomon codes was constructed in a recent paper by I. Tamo and A. Barg (IEEE Trans. Inform. Theory, no. 8, 2014).

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Quantum codes derived from cyclic codes

, 2017
In this note, we present a construction of new nonbinary quantum codes with good parameters. These codes are obtained by applying the Calderbank-Shor-Steane (CSS) construction.

On the decomposition of cyclic codes into cyclic classes

Information and Control, 1971
The problem of finding the cycle representatives of a cyclic code is examined. For an (n, k) cyclic code whose parity check polynomial h(x) consists entirely of factors with exponent n, a complete set of representatives is obtained. Further, if the exponents of the factors of h(x) are relatively prime to each other, a complete set can also be generated.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Finding Cliques in Projective Space: A Method for Construction of Cyclic Grassmannian Codes

IEEE Access, 2020
In general, the construction of subspace codes or, in particular, cyclic Grassmannian codes in some projective space Pq(n) is highly mathematical and requires substantial computational power for the resulting searches.

Optimal Linear and Cyclic Locally Repairable Codes over Small Fields

, 2015
We consider locally repairable codes over small fields and propose constructions of optimal cyclic and linear codes in terms of the dimension for a given distance and length.

Cyclically permutable representations of cyclic codes

Discrete Applied Mathematics, 2008
A cyclically permutable code is a binary block code of length \(n\) such that each codeword has \(n\) distinct cyclic shifts and such that no codeword can be obtained by one or more cyclic shifts of another codeword. Cyclically permutable codes have been studied for several applications involving synchronization, code-division multiple access (CDMA ...
