Under research for near sixty years, Bose-Ray-Chaudhuri-Hocquenghem(BCH) codes have played increasingly important roles in many applications such as communication systems, data storage and information security. However, the dimension and minimum distance of BCH codes are seldom solved until now because of their intractable characteristics. The objective of this paper is to study the dimensions ...

We describe a novel nucleoside analog, 2'-deoxy-3'-thiacytidine (BCH-189), in which the 3' carbon of the ribose ring of 2'-deoxycytidine has been replaced by a sulfur atom. In MT-4 T cells, this compound had significant time- and dose-dependent antiviral activity against five different strains of human immunodeficiency virus type 1 (HIV-1) (mean 50% inhibitory dose, 0.73 microM); known 3'-azido...

We study flavor changing effects on the pp → bcH ± + X process at the Large Hadron Collider(LHC), which are inspired by the left-handed up-type squark mixings in the Minimal Supersymmetric Standard Model(MSSM). We find that the SUSY QCD radiative corrections to bcH ± coupling can significantly enhance the cross sections at the tree-level by a factor about 1.5 ∼ 5 with our choice of parameters. ...

Affine-invariant codes are extended cyclic codes of length pm invariant under the affine-group acting on Fpm . This class of codes includes codes of great interest such as extended narrow-sense BCH codes. In recent papers, we classified the automorphism groups of affine-invariant codes [2], [5]. We derive here new results, especially when the alphabet field is an extension field, by expanding o...

Benign cephalic histiocytosis (BCH) is a rare type of non-Langerhans histiocytosis with features of many small yellow, yellow-red, or yellow-brown papules located on face, head, neck, and shoulders of infants and young children. There would be no associated symptoms. The histopathological images reveal infiltration of histiocytes in dermis; immunohistochemically, the histiocytes are positive fo...

Investigaciones sobre toxicidad ambiental por pesticidas se han realizado principalmente en mamíferos terrestres, pero existe poca información plaguicidas organoclorados murciélagos. Teniendo cuenta el papel funcional de este grupo varios procesos ecosistémicos como insectívoros, frugívoros y polinizadores, su afectación puede estar causando un impacto negativo la salud los ecosistemas naturale...

In this paper, a new procedure for decoding cyclic and BCH codes up to their actual minimum distance is presented. Previous algebraic decoding procedures for cyclic and BCH codes such as the Peterson decoding procedure and our procedure using nonrecurrent syndrome dependence relations can be regarded as special cases of this new decoding procedure. With the aid of a computer prokram, it has bee...

The baseband signal of the 406 MHz COSPAS-SARSAT emergency beacon is a 144-bit or 112-bit data with 0 and 1 code, including information bits error correcting check bits. In order to improve coding efficiency for transmitter in STM32 micro-controller, this paper proposes calculation method first BCH code (BCH-1) second (BCH-2) COSPAS-SARAST transmitter. First, conduct process by 64-bit integral ...

This article aims to study recycled biochar (R-BCH) improvements on the high-density polyethylene (HDPE) matrix properties. A series of composites was developed with a different loading varying from 0 10 wt.% R-BCH, using twin-screw extruder followed by compression molding. The results were showed that addition 3-10% R-BCH in pure HDPE led an increase tensile strength, modulus elasticity, and d...
