We define generalized Hamming weights for almost affine codes. We show that this definition is natural since we can extend some well known properties of t he generalized Hamming weights for linear codes, to almost affine codes. In addition we discus s duality of almost affine codes, and of the smaller class of multilinear codes.

Aim: <br>Evidence shows that many patients are detected and treated late in their course of illness, and that substantial delay occurs even after entry to mental health services. Although several studies have examined the service user and carer perspectives on treatment delay, few have explored the issue from the service provider perspective. The aim of this study was to broaden our understanding ...

Background:<br> Processing of fish and shellfish may result in substantial amounts of by-products and unless they can be used as food, the most realistic option in most cases is the production of preserved feed nutrients. If large volumes are available, reduction to fishmeal and fish oil is the preferred technology. However, fresh by-products are most often available in insufficient quantities ...

Here we report a series of close analogues of our recently published scaffold-based tripeptidomimetic CXCR4 antagonists, containing positively charged guanidino groups in R1 and R2, and an aromatic group in R3. While contraction/elongation of the guanidine carrying side chains (R1 and R2) resulted in loss of activity, introduction of bromine in position 1 on the naphth-2-ylmethyl moiety (R3 ...

I fokus för denna studie står läsaren och bokmarknaden under tiden för det moderna genombrottet, och då framför allt perioden 1879–90. Studien bygger på en komparativ undersökning av tre olika typer av bokinstitutioner, som tillsammans kan sägas ha utgjort ett tvärsnitt av dåtidens svenska bokmarknad: Gumperts bokhandel i Göteborg, sockenbiblioteket i Munka-Ljungby och Sjöbloms lånebibliotek i Lund. ...

The extinct passenger pigeon was once the most abundant bird in North America, and possibly the world. Although theory predicts that large populations will be more genetically diverse, passenger pigeon genetic diversity was surprisingly low. To investigate this disconnect, we analyzed 41 mitochondrial and 4 nuclear genomes from passenger pigeons and 2 genomes from band-tailed pigeons, which are ...

Commercially available microarray (IDENTIBAC AMR-ve) for the detection of antibiotic resistance determinants was investigated for its potential to genotype 30 clinical isolates and two control strains of Klebsiella pneumoniae. Resistance profiles and the production of extended-spectrum b-lactamases were determined by disc diffusion and the results were compared with the microarray profiles in order ...

Identifying optimal dosing of antibiotics has proven challenging—some antibiotics are most effective when they are administered periodically at high doses, while others work best when minimizing concentration fluctuations. Mechanistic explanations for why antibiotics differ in their optimal dosing are lacking, limiting our ability to predict optimal therapy and leading to long and costly experiments. ...

A key outstanding issue in adaptive evolution is the relationship between the genetics of intraspecific polymorphism and interspecific evolution. Here, we show that the pale/dark ventral plumage polymorphism that occurs in both the pomarine skua (Stercorarius pomarinus) and Arctic skua (S. parasiticus) is the result of convergent evolution at the same locus (MC1R), involving some of the same amino ...

Reproducible climate reconstructions of the Common Era (1 CE to present) are key to placing industrial-era warming into the context of natural climatic variability. Here we present a community-sourced database of temperature-sensitive proxy records from the PAGES2k initiative. The database gathers 692 records from 648 locations, including all continental regions and major ocean basins. The records ...
