ON HYBRID INTERIOR IDEALS IN SEMIGROUPS

In this paper, we introduce the notion of hybrid interior ideals and hybrid characteristic interior ideals of a semigroup. We obtain some equivalent conditions for a hybrid structure to be a hybrid interior ideal of a semigroup. Also, we show that hybrid interior ideals and hybrid ideals coincide for a regular semigroup and a intra-regular semigroup

An Assessment of Onshore and Offshore Wind Energy Potential in India Using Moth Flame Optimization

Wind energy is one of the supremely renewable energy sources and has been widely established worldwide. Due to strong seasonal variations in the wind resource, accurate predictions of wind resource assessment and appropriate wind speed distribution models (for any location) are the significant facets for planning and commissioning wind farms. In this work, the wind characteristics and wind potential assessment of onshore, offshore, and nearshore locations of India—particularly Kayathar in Tamilnadu, the Gulf of Khambhat, and Jafrabad in Gujarat—are statistically analyzed with wind distribution methods. Further, the resource assessments are carried out using Weibull, Rayleigh, gamma, Nakagami, generalized extreme value (GEV), lognormal, inverse Gaussian, Rician, Birnbaum–Sandras, and Bimodal–Weibull distribution methods. Additionally, the advent of artificial intelligence and soft computing techniques with the moth flame optimization (MFO) method leads to superior results in solving complex problems and parameter estimations. The data analytics are carried out in the MATLAB platform, with in-house coding developed for MFO parameters estimated through optimization and other wind distribution parameters using the maximum likelihood method. The observed outcomes show that the MFO method performed well on parameter estimation. Correspondingly, wind power generation was shown to peak at the South West Monsoon periods from June to September, with mean wind speeds ranging from 9 to 12 m/s. Furthermore, the wind speed distribution method of mixed Weibull, Nakagami, and Rician methods performed well in calculating potential assessments for the targeted locations. Likewise, the Gulf of Khambhat (offshore) area has steady wind speeds ranging from 7 to 10 m/s with less turbulence intensity and the highest wind power density of 431 watts/m2. The proposed optimization method proves its potential for accurate assessment of Indian wind conditions in selected locations.publishedVersio

Effects of Cooking Methods and in-vitro Digestion on the Digestibility and Antioxidant Properties of Ngari (a fermented fish product of India)

Ngari is a popular ethnic fermented fish product from North-Eastern India. It is consumed after heat process either as a part of regular meal or as a condiment. However, there is no adequate knowledge on the digestion of Ngari and the bioactive potential of the digest. The present study was aimed to evaluate the effect of different heat processes viz., air frying, roasting and sautéing-on the chemical attributes and in-vitro digestion characteristics of Ngari with reference to digestibility and antioxidant potential. The different heat processes significantly increased the dry matter content, thereby altering the proximate composition of the Ngari. Nutritional analyses revealed that highest value of protein is in air fried Ngari (44.14%), while maximum fat in sautéed Ngari (27.57%). Fatty acids analysis showed that palmitic, oleic and linoleic acid were the major fatty acids present in Ngari irrespective of different heat processing. Antioxidant potential of Ngari was significantly influenced by heating processes and digestion methods (pepsin or pepsin-cum-pancreatin). Heat processes significantly reduced DPPH (2,2-diphenyl-1-picrylhydrazyl) and metal chelating activity, while increasing the reducing power of the Nagri. Study of peptide released during digestion by SDS-PAGE (Sodium lauryl sulphate-polyacrylamide gel electrophoresis) showed that pepsin digestion led to formation of low molecular weight peptides (14-66 kDa). Subsequently, the pepsin-cum-pancreatin digestion disintegrated the relatively larger peptides into further smaller ones. The different heat processes enhanced the sensory appeal of the product without exerting any negative influence on its digestibility and bioactive properties

Unique cellular immune signatures of multisystem inflammatory syndrome in children

The clinical presentation of MIS-C overlaps with other infectious/non-infectious diseases such as acute COVID-19, Kawasaki disease, acute dengue, enteric fever, and systemic lupus erythematosus. We examined the ex-vivo cellular parameters with the aim of distinguishing MIS-C from other syndromes with overlapping clinical presentations. MIS-C children differed from children with non-MIS-C conditions by having increased numbers of naïve CD8(+) T cells, naïve, immature and atypical memory B cells and diminished numbers of transitional memory, stem cell memory, central and effector memory CD4(+) and CD8(+) T cells, classical, activated memory B and plasma cells and monocyte (intermediate and non-classical) and dendritic cell (plasmacytoid and myeloid) subsets. All of the above alterations were significantly reversed at 6–9 months post-recovery in MIS-C. Thus, MIS-C is characterized by a distinct cellular signature that distinguishes it from other syndromes with overlapping clinical presentations.
