Embodiments of the invention provides a decoder for decoding a signal received through a transmission channel in a communication system, said signal carrying information symbols selected from a given alphabet and being associated with a signal vector, said transmission channel being represented by a channel matrix, wherein said decoder comprises: a sub-block division unit (301) configured to divide the received signal vector into a set of sub-vectors in correspondence with a division of a matrix related to said channel matrix;a candidate set estimation unit (305) for recursively determining candidate estimates of sub-blocks of the transmitted signal corresponding to said sub-vectors, each estimate of a given sub-block being determined from at least one candidate estimate of the previously processed sub-blocks,wherein said candidate set estimation unit is configured to determine a set of candidate estimates for at least one sub-block of the transmitted signal by applying at least one iteration of a decoding algorithm using the estimates determined for the previously processed sub-blocks, the number of candidate estimates determined for said sub-block being strictly inferior to the cardinal of the alphabet and superior or equal to two, the decoder further comprising a signal estimation unit (306) for calculating an estimate of the transmitted signal from said candidate estimates determined for said sub-blocks.

Methods and apparatus to parallelize data decompression are disclosed. An example method adjusting a first one of initial starting positions to determine a first adjusted starting position by decoding the bitstream starting at a training position in the bitstream, the decoding including traversing the bitstream from the training position as though first data located at the training position is a valid token; and merging, by executing an instruction with the processor, first decoded data generated by decoding a first segment of the compressed data bitstream starting from the first adjusted starting position with second decoded data generated by decoding a second segment of the compressed data bitstream, the decoding of the second segment starting from a second position in the compressed data bitstream and being performed in parallel with the decoding of the first segment, and the second segment preceding the first segment in the compressed data bitstream.

A system, method and computer program product for encoding an input string of binary characters representing alphanumeric characters. A system includes: a character writing engine for writing a binary character to an empty cell of a multi-dimensional shape beginning with a starting empty cell; a next cell determination engine for determining a next empty cell by traversing neighboring cells in the multi-dimensional shape until an empty cell is located; a loop facilitator for looping back to the character writing engine and the next cell determining engine until no more data characters or a next empty cell is not determined; and a serialization engine for serializing the cells into a one dimensional binary string of characters representing an encoded string of alphanumeric characters.

An encoder for encoding input data (D1) to generate corresponding encoded data (E2) includes data processing hardware which is operable: (a) to determine at least partial reoccurrences of data blocks or data packets within the input data (D1), wherein the data blocks or data packets include a plurality of bytes;(b) to employ at least one reference symbol to relate reoccurrences of mutually similar data blocks or data packets and/or to indicate whether or not there are reoccurrences of mutually similar data blocks or data packets within the input data (D1);(c) to employ a plurality of change symbols, for example a plurality of mask bits, to indicate changed and unchanged data elements of partial reoccurrences of data blocks or data packets within the input data (D1) and a change of data values of changed data elements; and(d) to encode the at least one reference symbol and the plurality of change symbols into the encoded data (E2). There are provided methods of using the encoder to encode input data (D1) to generate the corresponding encoded data (E2).

AT LAST there appears to be some momentum gathering behind what I have been saying for weeks: that it is wrong to lock down people on the grounds of age alone.

O TEMPORA! O mores! One of the most senior figures in the Civil Service, Sir Philip Rutnam, calls a press conference to denounce his Minister, in this case the Home Secretary herself. How times have changed from when civil servants were anonymous and Ministers took the flak when things went wrong.

IT IS TIME that political interference with the police and the CPS ceased. One might have thought that after the ludicrous Operation Midland , the lesson had been learned.

I have been grateful for the restrained response of this government towards the coronavirus outbreak but the new proposal to lock down every single person over the age of 70 for three months, regardless of health and strength, seems woefully lacking in logic.

THIS is a story of two businesses and of two very different approaches to our current exigencies.The first concerns my local laundry CleanCall, which devised a means to keep going and contributing to the economy.

SO, BORIS, where is your land of liberty now? Where is proportionality and reason?

I'M QUITE enjoying this lockdown but I know just how blessed I am. I actively like solitude. I have the moors on my doorstep, a large garden, a job which I can do from home, a dependable pension, good health and a keyworker neighbour who can drop off fresh milk, bread and veg.

OH, FOR pity's sake! Death is stalking the country, the NHS is over-run, the economy is crashing on a seismic scale but Ofcom is pontificating about broadcaster Piers Morgan's mimicry of a Chinese accent calling it "offensive and racist". Get a life, dears!

BACK ON Wednesday, March 18, I wrote that as the overwhelming majority of people who were dying were reported as having underlying health conditions it would make sense to lock down anybody with such a condition and let the rest of us get on with keeping the economy and the volunteer effort going.

BY AND large I resist the temptation to roar at my TV screen but a few days ago, I did just that, when the tearful sister of twins who had died from the virus commented that she could not even be with her parents. Why the hell not? I shouted, feeling close to tears myself.

AT LAST there appears to be some momentum gathering behind what I have been saying for weeks: that it is wrong to lock down people on the grounds of age alone.

Extracytoplasmic sugar decoration of glycopolymer components of the bacterial cell wall contributes to their structural diversity. Typically, the molecular mechanism that underpins such a decoration process involves a three-component glycosylation system (TGS) represented by an undecaprenyl-phosphate (Und-P) sugar-activating glycosyltransferase (Und-P GT), a flippase, and a polytopic glycosyltransferase (PolM GT) dedicated to attaching sugar residues to a specific glycopolymer. Here, using bioinformatic analyses, CRISPR-assisted recombineering, structural analysis of cell wall–associated polysaccharides (CWPS) through MALDI-TOF MS and methylation analysis, we report on three such systems in the bacterium Lactococcus lactis. On the basis of sequence similarities, we first identified three gene pairs, csdAB, csdCD, and csdEF, each encoding an Und-P GT and a PolM GT, as potential TGS component candidates. Our experimental results show that csdAB and csdCD are involved in Glc side-chain addition on the CWPS components rhamnan and polysaccharide pellicle (PSP), respectively, whereas csdEF plays a role in galactosylation of lipoteichoic acid (LTA). We also identified a potential flippase encoded in the L. lactis genome (llnz_02975, cflA) and confirmed that it participates in the glycosylation of the three cell wall glycopolymers rhamnan, PSP, and LTA, thus indicating that its function is shared by the three TGSs. Finally, we observed that glucosylation of both rhamnan and PSP can increase resistance to bacteriophage predation and that LTA galactosylation alters L. lactis resistance to bacteriocin.
