Existence and Construction of LCD codes over Finite Fields

We demonstrate the existence of Euclidean and Hermitian LCD codes over finite fields with various parameters. In addition, we provide a method for constructing multiple Hermitian LCD (self orthogonal, self dual) codes from a given Hermitian LCD (self orthogonal, self dual) code, as well as a method for constructing Euclidean (Hermitian) LCD codes with parameters $[n+1, k+1]$ and $[n,k+1]$ from a given Euclidean (Hermitian) LCD code with parameters $[n,k]$ over finite fields. Finally, we provide some findings on $\sigma$-LCD codes over finite fields

Dodatak supranutritivnih doza cinkova sulfata i bakterija Bacillus firmus ubijenih toplinom u obrok rano odbijenih svinja: utjecaj na rast, funkciju neutrofila i upalne citokine

The objective of the study was to investigate the effect of supplementation of a supranutritional dose of zinc sulfate (ZnSO4) and Bacillus firmus derived bio-response modifier (BRM) on growth, blood neutrophil functions, pro-inflammatory and anti-inflammatory cytokine responses in early weanling piglets. In total, 45 piglets (age of 19.25 ± 0.84 days) were randomly divided into five groups: I (basal diet only), II (basal diet supplemented with ZnSO4), III (basal diet supplemented with BRM), IV (basal diet supplemented with ZnSO4 plus BRM) and V (basal diet without weaning from dam). The production of myeloperoxidase (MPO) and superoxide anion (O2-), and the concentration of transforming growth factor-β1 (TGF-β1) were markedly reduced, whereas the concentrations of intercellular adhesion molecule 1 (ICAM1), and monocyte chemoattractant protein 1 (MCP1) were significantly (P0.05) but a marked increase (P0,05), ali kod prasadi iz skupine II. i III. je 14. i 7. dana opaženo znakovito povišenje (P<0,05) ICAM1, MCP1, te sniženje koncentracije TGF-β1. U prasadi iz skupine IV dodavanje BRM i ZnSO4 u osnovnom obroku poboljšalo je MPO (2. dan) i O2- (7. dan), bez znakovitih promjena u rastu i koncentraciji citokina. Na kraju, zaključeno je da dodavanje kombinacije BRM i ZnSO4 u obroku potiče urođenu imunost prasadi što nije slučaj kada se ZnSO4 ili BRM dodaju zasebno. Rezultati ovog istraživanja pomoći će u formuliranju učinkovitog upravljanja hranidbom kod rano odbijene prasadi u krdu svinja

Germplasm characterization, association and clustering for salinity and waterlogging tolerance in bread wheat (Triticum aestivum)

A study was conducted for characterizing germplasm, estimating interrelationship of traits and clustering of wheat genotypes in five environments covering salinity, waterlogging and neutral soils using, 100 elite but diverse genotypes with eight checks of bread wheat (Triticum aestivum L.). These genotypes were planted under five distinct environments during rabi 2009-10 under augmented design in four blocks wherein each check was repeated twice. The genetic variance, correlation coefficients and cluster analysis were carried out for assessment of lines through seven metric traits, namely, plant stand, plant height, days to heading, days to maturity, tillers/meter, 1000-grain weight and grain yield. Analysis of variance revealed wide variability for most of the traits under study. The phenotypic coefficient of variation (PCV) was high for tillers/meter and grain yield, while high heritability coupled with high genetic advance were found for tillers/meter, 1000-grain weight and grain yield under all five environments. At phenotypic level, positive and significant correlation coefficients revealed that under all the normal and stressed environments used here, grain yield is directly influenced by plant stand, tillers/meter and thousand grain weights. Significant and positive correlations were estimated between tillers/meter (r = 0.31 to 0.66), and 1000 grain weight (r = 0.24 to 0.61) with grain yield under all five environments. Under waterlogged conditions there were significant negative correlations of plant height to grain yield (r = –0.38 to –0.39) across two sites. These results, thereby suggests that yield improvement in bread wheat could be possible by emphasizing these traits through selection in these diverse environments. On the basis of D2 values of pooled data, 108 genotypes were grouped into four clusters. In all, only 26 lines were found common in cluster III under two waterlogging environments (Faizabad and Karnal), while only 15 lines were common in cluster I under non waterlogging (Faizabad, CSSRI and DWR) conditions. These results indicate different constraints exist in waterlogged and non-waterlogged condition at these sites. Genetic diversity available for these traits may be utilized for yield improvement in bread wheat under different soil conditions through planned hybridization and selection in target environments

Identification of putative RuBisCo activase (TaRca1) ˗ the catalytic chaperone regulating carbon assimilatory pathway in wheat (Triticum aestivum) under the heat stress

RuBisCo activase (Rca) is a catalytic chaperone involved in modulating the activity of RuBisCo (key enzyme of photosynthetic pathway). Here, we identified eight novel transcripts from wheat through data mining predicted to be Rca and cloned a transcript of 1.4 kb from cv. HD2985, named as TaRca1 (GenBank acc. no. KC776912). Single copy number of TaRca1 was observed in wheat genome. Expression analysis in diverse wheat genotypes (HD2985, Halna, PBW621 and HD2329) showed very high relative expression of TaRca1 in Halna under control and HS-treated, as compared to other cultivars at different stages of growth. TaRca1 protein was predicted to be chloroplast-localized with numerous potential phosphorylation sites. Nothern blot analysis showed maximum accumulation of TaRca1 transcript in thermotolerant cv. during mealy-ripe stage, as compared to thermosusceptible. Decrease in the photosynthetic parameters was observed in all the cultivars, except PBW621 in response to HS. We observed significant increase in the Rca activity in all the cultivars under HS at different stages of growth. HS causes decrease in the RuBisCo activity; maximum reduction was observed during pollination stage in thermosusceptible cvs. as validated through immunoblotting. We observed uniform carbon distribution in different tissues of thermotolerant cvs., as compared to thermosusceptible. Similarly, tolerance level of leaf was observed maximum in Halna having high Rca activity under HS. A positive correlation was observed between the transcript and activity of TaRca1 in HS-treated Halna. Similarly, TaRca1 enzyme showed positive correlation with the activity of RuBisCo. There is, however, need to manipulate the thermal stability of TaRca1 enzyme through protein engineering for sustaining the photosynthetic rate under HS – a novel approach towards development of ‘climate-smart’ crop

The Astropy Project: Sustaining and Growing a Community-oriented Open-source Project and the Latest Major Release (v5.0) of the Core Package*

The Astropy Project supports and fosters the development of open-source and openly developed Python packages that provide commonly needed functionality to the astronomical community. A key element of the Astropy Project is the core package astropy, which serves as the foundation for more specialized projects and packages. In this article, we summarize key features in the core package as of the recent major release, version 5.0, and provide major updates on the Project. We then discuss supporting a broader ecosystem of interoperable packages, including connections with several astronomical observatories and missions. We also revisit the future outlook of the Astropy Project and the current status of Learn Astropy. We conclude by raising and discussing the current and future challenges facing the Project
