Salmonella typhimurium invasion of nonphagocytic cells requires the expression of a type III secretion system (TTSS) encoded within Salmonella pathogenicity island 1 (SPI1). TTSS gene transcription is activated in response to environmental signals and requires transcriptional regulators encoded within (HilA) and outside (SirA) SPI1. Two unique loci, sirB and sirC, which contribute to SPI1 gene ...

This article concerns the SIRC epidemiological model for influenza A, which efficiently describes the mechanism of disease spreading, including the susceptible (S), the infected (I) and the recovered (R), along with a crossimmune class (C) that recovers after being inflected by different strains of the same viral subtype. The dynamics of the model is completely determined by the basic reproduct...

Adherence of Pseudomonas aeruginosa to a Rabbit Cornea Cell Line (SIRC) cells in vitro was examined. Maximal adherence occurred at pH 5. 0-7. 0 and when the bacterial ~~spension at 1. 4x109 /ml was exposed to 2x104/ml SIRC cells at mid-logarithmic growth phase. Adherence was not affected by temperature. In the passage of time, a temporary rise of adherence occurred within 5 min of incubation an...

This article presents a novel compact self-quintuplexing antenna architecture based on substrate-integrated rectangular cavity (SIRC) for pentaband applications. The proposed is constructed by employing an SIRC, one Pi-shaped slot (PSS), T-shaped (TSS), and five 50Ω microstrip feedlines. PSS TSS are engraved the top of SIRC to create radiating patches, which excited feedlines achieve operation ...

In Bacillus megaterium, the synthesis of vitamin B(12) (cobalamin) and sirohaem diverges at sirohydrochlorin along the branched modified tetrapyrrole biosynthetic pathway. This key intermediate is made by the action of SirC, a precorrin-2 dehydrogenase that requires NAD(+) as a cofactor. The structure of SirC has now been solved by X-ray crystallography to 2.8 A (1 A = 0.1 nm) resolution. The p...

In this paper, A Chebyshev spectral method is presented to study the deals with the fractional SIRC model associated with the evolution of influenza A disease in human population. The properties of the Chebyshev polynomials are used to derive an approximate formula of the Caputo fractional derivative. This formula reduces the SIRC model to the solution of a system of algebraic equations which i...

Supernatants of a primary rabbit corneal epithelial cell culture and an established corneal cell line (SIRC) were assayed for their ability to enhance mitogen-induced C3H/HeJ mouse thymocyte proliferation. Significant levels of thymocyte-enhancing activity were detected in supernatants from both primary cultures and SIRC. Maximal levels of activity were found after 48 to 72 hr of culture in ser...

In this paper, we propose Secure Intermittent-Robust Computation (SIRC) for Energy Harvesting Powered Internet of Things (IoT) Devices. This effort innovates a new duty-cycle-variable computing approach to facilitate and invigorate security in energyharvesting-powered IoT network nodes. The proposed SIRC architecture is developed from the ground up by extending emerging postCMOS switching eleme...

Abstract Based on the Buckland Professor lecture for 2021–2022, this story uses a hypothetical sketch of how relationship between fishing industry and scientists evolved over last century to provide starting point personal account changes in Science Industry Research Collaboration (SIRC). After period doldrums, SIRC is burgeoning debate practice. Focussing experiences European arena, looks at w...
