TL;DR: In this article, the concept of two-dimensional (2D) color barcode, also known as color quick response (QR) pattern generation, was introduced and integrated as an automatic method to produce the cancelable biometric template with improved recognition accuracy.
Abstract: This paper introduces the concept of two-dimensional (2D) color barcode, also known as color quick response (QR) pattern generation, and integration as an automatic method to produce the cancelable biometric template with improved recognition accuracy. It includes various methodologies for multi-modal based generation of biometric template, cipher conversion, diversity, irreversible property, etc. In this work, based on application of different attributes to four different biometric traits combining feature selection and fusion techniques, subsequently three templates are generated. However, in general, cancelable biometrics(CB) come with some systematic template distortion, which directly depends on input biometric characteristics to protect sensitive information. This will degrade the system performance when input deals with multiple biometric traits in the multi-biometric system. To address these issues, with the notion of color variant QR pattern analysis, dynamic constrained random key generation is introduced to generate CB templates. These templates can replace all other existing CB systems without compromising the quality metrics due to an independent transformation model for an authentication factor.

TL;DR: In this article, a triple antigen chimeric protein (HAB) was proposed to induce innate, humoral and cellular immune responses for Staphylococcus aureus.
Abstract: Staphylococcus aureus is a serious pathogen unleashing its virulence through several classes of exotoxins such as hemolysins and enterotoxins. In this study, we designed a novel multi-antigen subunit vaccine which can induce innate, humoral and cellular immune responses. Alpha hemolysin, enterotoxins A and B were selected as protective antigens for combining into a triple antigen chimeric protein (HAB). Immunoinformatics analysis predicted HAB protein as a suitable vaccine candidate for inducing both humoral and cellular immune responses. Tertiary structure of the HAB protein was predicted and validated through computational approaches. Docking studies were performed between the HAB protein and mice TLR2 receptor. Furthermore, we constructed and generated recombinant HAB (r-HAB) protein in E. coli and studied its toxicity, immunogenicity and protective efficacy in a mouse model. Triple antigen chimeric protein (r-HAB) was found to be highly immunogenic in mouse as the anti-r-HAB hyperimmune serum was strongly reactive to all three native exotoxins on Western blot. In vitro toxin neutralization assay using anti-r-HAB antibodies demonstrated > 75% neutralization of toxins on RAW 264.7 cell line. Active immunization with r-HAB toxoid gave ~ 83% protection against 2 × lethal dosage of secreted exotoxins. The protection was mediated by induction of strong antibody responses that neutralized the toxins. Passive immunization with anti-r-HAB antibodies gave ~ 50% protection from lethal challenge. In conclusion, in vitro and in vivo testing of r-HAB found the molecule to be nontoxic, highly immunogenic and induced excellent protection towards native toxins in actively immunized and partial protection to passively immunized mice groups. • HAB protein was computationally designed to induce humoral and cellular responses.
• r-HAB protein was found to be nontoxic, immunogenic and protective in mouse model.
• r-HAB conferred protection against lethal challenge in active and passive immunization.

TL;DR: In this paper, the SnO2 nanoflakes were used as an anode material for the fabrication of lithium-ion battery (LIB) by simple one-step facile microwave-assisted solvothermal synthesis.
Abstract: The SnO2 nanoflakes were prepared by simple one-step facile microwave-assisted solvothermal synthesis. The as-prepared SnO2 nanoflakes were systematically studied using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and high-resolution transmission electron microscopy (HR-TEM). From FE-SEM images seen that SnO2 nanoparticles are stocked between the SnO2 nanoflakes and also, pores are existed between the SnO2 flakes. TEM results reveal that the SnO2 nanoflakes were formed due to the self-assembly of very thin SnO2 nanosheets and also pores coexist between the sheets. The prepared SnO2 nanoflakes are used as an anode material for the fabrication of lithium-ion battery (LIB). The SnO2 nanoflakes electrode was found to show a stable reversible lithium storage capacity of 567 mA h g−1 even at a current density of 500 mA g−1 after 50 cycles. The enhanced properties in terms of reversible capacity and cycle ability of the SnO2 nanoflakes as an anode material are owing to its porous nature, which facilitates more lithium storage and interconnection between the flakes and particles enhance the kinetic properties of the electrode material. Hence, the developed SnO2 nanoflakes by simple one-step facile microwave-assisted solvothermal synthesis can be a stable and high rate anode material for lithium-ion batteries.

03 Nov 2011TL;DR: A validated EAF and STATCOM model was developed and it was applied in the simulation studies of cascaded H-bridge converter based Distribution STATic synchronous COMpensator (DSTATCOM) for voltage flicker mitigation.
Abstract: This paper presents simulation study of an Electric Arc Furnace (EAF) model in the MATLAB/SIMULINK environment. EAF was modeled as a time domain controlled voltage source (CVS) model. Voltage flicker, a phenomenon of annoying light intensity fluctuation, caused by EAF, has been a major power quality concern for both power companies and customers. A model was developed for the EAF and it was applied in the simulation studies of cascaded H-bridge converter based Distribution STATic synchronous COMpensator (DSTATCOM) for voltage flicker mitigation. The controller for DSTATCOM was designed based on d-q model for the reactive power management, which helps in the mitigation of the flicker. With the validated EAF and STATCOM model, simulations are conducted to study the response of the compensator in the distribution system.

01 Jan 2019TL;DR: This chapter discusses various applications of plant nanobionics in detail, in which engineered nanomaterials are combined with plant organelles to enhance the function of plants.
Abstract: Nanotechnology is an interesting field in which molecules that are not visible to our eyes are creating wonders. They exist in various fields of engineering and science such as electronics, agriculture, food, pharmaceuticals, and medical diagnostics, and many researchers are eyeing provision of better technology with these nanotechnological inventions. Nanomaterials show great promise, owing to their unique physicochemical properties, in the field of agriculture. Plants interact with these nanoparticles, resulting in various morphological, physiological, and genotoxic changes. Understanding of their interactions is very important for real gains in the potential use of nanotechnology in agriculture. Nanoparticles have been described as “magic bullets.” Nanoparticles can play a vital role in the growth of plants and help in the process of photosynthesis. They also influence the key processes that take place in the growth of plants, such as seed germination, root initiation, and the photosynthetic process. Plant nanobionics is a current topic in which engineered nanomaterials are combined with plant organelles to enhance the function of plants. This chapter discusses various applications of plant nanobionics in detail.
