Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that is characterized by loss of intellectual functioning of brain and memory loss. According to amyloid cascade hypothesis, aggregation of amyloid-β42 (Aβ42) peptide can generate toxic oligomers and their accumulation in the brain is responsible for the onset of AD. In spite of carrying out a large number of experimental studies on inhibition of Aβ42 aggregation by small molecules, the detailed inhibitory mechanism remains elusive. In the present study, comparable molecular dynamics (MD) simulations were performed to elucidate the inhibitory mechanism of a sulfonamide inhibitor C1 (2,5-dichloro-N-(4-piperidinophenyl)-3-thiophenesulfonamide), reported for its in vitro and in vivo anti-aggregation activity against Aβ42. MD simulations reveal that C1 stabilizes native α-helix conformation of Aβ42 by interacting with key residues in the central helix region (13–26) with hydrogen bonds and π–π interactions. C1 lowers the solvent-accessible surface area of the central hydrophobic core (CHC), KLVFF (16–20), that confirms burial of hydrophobic residues leading to the dominance of helical conformation in the CHC region. The binding free energy analysis with MM–PBSA demonstrates that Ala2, Phe4, Tyr10, Gln15, Lys16, Leu17, Val18, Phe19, Phe20, Glu22, and Met35 contribute maximum to binding free energy (−43.1 kcal/mol) between C1 and Aβ42 monomer. Overall, MD simulations reveal that C1 inhibits Aβ42 aggregation by stabilizing native helical conformation and inhibiting the formation of aggregation-prone β-sheet conformation. The present results will shed light on the underlying inhibitory mechanism of small molecules that show potential in vitro anti-aggregation activity against Aβ42. © 2017 Informa UK Limited, trading as Taylor & Francis Group

Orthogonal rotation invariant moments (ORIMs) are among the best region based shape descriptors. Being orthogonal and complete, they possess minimum information redundancy. The magnitude of moments is invariant to rotation and reflection and with some geometric transformation, they can be made translation and scale invariant. Apart from these characteristics, they are robust to image noise. These characteristics of ORIMs make them suitable for many pattern recognition and image processing applications. Despite these characteristics, the ORIMs suffer from many digitization errors, thus they are incapable of representing subtle details in image, especially at high orders of moments. Among the various errors, the image discretization error, geometric and numerical integration errors are the most prominent ones. This paper investigates the contribution and effects of these errors on the characteristics of ORIMs and performs a comparative analysis of these errors on the accurate computation of the three major ORIMs: Zernike moments (ZMs), Pseudo Zernike moments (PZMs) and orthogonal Fourier-Mellin moments (OFMMs). Detailed experimental analysis reveals some interesting results on the performance of these moments. © 2013 Springer Science+Business Media New York.

Zernike moments (ZMs) are very effective global image descriptors which are used in many digital image processing applications. The digitization process compromises the accuracy of the moments and therefore, several of its properties are affected. There are two major discretization errors, namely, the geometric error and numerical integration error. In this paper we propose two new algorithms which eliminate these errors. The first algorithm performs the exact computation of geometric moments (GMs) over a unit disk and then uses GMs-to-ZMs relationship to compute the latter. This algorithm is computationally more expensive and it becomes numerically instable for higher order moments, therefore, we develop a second algorithm based on Gaussian quadrature numerical integration. The second algorithm reduces both the errors simultaneously and its accuracy increases as the degree of Gaussian quadrature numerical integration increases. The proposed algorithms are observed to provide very accurate ZMs which result in improved image reconstruction, reduction in reconstruction error and improvement in rotation and scale invariance. Exhaustive experiments are provided to support improved accuracy of ZMs and time complexity analysis is performed for the existing and the proposed methods. © 2013 Elsevier Inc. All rights reserved.

With the aim of designing long-haul, back-to-back, and amplitude-phase-modulated optical OFDM systems, we carry out a simulative analysis for averaging the optimum value of the relative intensityto- noise ratio (RIN). We find that for single-mode lasers a bias of 2 mA has the highest spurious-free dynamic range (SFDR) and low RIN, and for multimode lasers, a bias of 6 mA has the highest SFDR and low RIN. © 2012 Springer Science+Business Media New York.

Purification techniques like ozonization, chlorination and filtration have their own limitations of corresponding energy sources and harmful waste generation. However, heterogeneous photo catalysis is used for producing oxidative agent (hydroxyl radical) which has been used as an environmentally harmonious decontamination process. Such safe and low energy consumable photo catalytic system is required for purification of polluted water. Degradation of dyes is a standard method to check the photocatalytic activity of any type of photo catalyst. In this paper thioglycerol capped and uncapped ZnS nanoparticles are studied in detail for their photocatalytic activity and generation of electron hole pairs. Bromophenol blue, crystal violet and reactive red dyes were successfully photo reduced using ZnS nanoparticles after 3.0. h of irradiation. Since the photocatalytic activity depends on the generation of electron hole pairs and the existence of different phases, we have tried to correlate the optical and morphological studies with these results to understand the phenomenon of photocatalytic activity at nanoscale. Though the Ultra violet irradiation can efficiently degrade the dyes, naturally abundant solar radiation is also very effective in the mineralization of dyes. Hence, it may be a viable technique for the safe disposal of textile wastewater into the water streams. © 2011 Elsevier Ltd.

Undoped and Copper (Cu) doped zinc oxide (ZnO) (Zn1 - xCuxO, x=0.01, 0.02, 0.03, 0.04 and 0.05) nanoparticles (NPs) capped with (1.0%) Thioglycerol (TG) have been successfully synthesized by co-precipitation method. The synthesized samples have been characterized by X-ray diffraction (XRD), Energy dispersive spectroscopy (EDS), Transmission electron microscopy (TEM), Photoluminescence (PL) and UV-Visible spectroscopy. Incorporation of impurity ions in pure ZnO NPs leads to a shift the spectra for both excitation and emission to visible region as compared to pure ZnO. The photocatalytic activity of undoped and Cu doped ZnO photocatalyst were investigated by the degradation of Crystal Violet (CV) dye in aqueous medium under exposure of UV-Visible light irradiations. Firstly, degradation of CV dye has been studied with TG capped, undoped and Cu doped ZnO NPs synthesized at pH-8.0. From the results, it has been found that Cu doping concentration of 3.0% is optimal for higher photophysical and photocatalytic properties. When pH of optimum doped NPs was varied from 8.0 to 10.0, 78.7% to 96.5% of CV dye has been degraded after 3.5h. Further increasing the pH to 12.0 for optimum doped NPs, 100% dye degrades in 2.5h. This shows that the doping and pH has a pronounced effect on the photocatalytic activity of ZnO NPs. Loading of catalyst shows maximum photodegradation of CV dye at 3.0g/L of Cu (3.0%) doped ZnO at pH-12.0 for 10mg/L of CV dye. Kinetic studies shows that photo degradation of CV follow a pseudo first-order kinetic law. The reason for enhanced degradation with Cu doped NPs in comparison to undoped NPs has been described and discussed in this work. © 2014 Elsevier Ltd.

The objective of this work is to develop gas sensors using tin oxide (SnO2) based thin films doped by Iron (Fe) and Indium (In) for good sensitivity and better response-recovery time. The structural properties and crystalline behavior of the synthesized films is studied by X-ray diffraction (XRD). The surface morphology and particle size is investigated by field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). The studies performed with energy-dispersive X-ray spectroscopy (EDS) confirmed the composition of the films. The sensitivity measurements are carried out as a function of operating temperature (50-350 °C) and at 400, 600 and 800 ppm partial pressure of chemical inputs. The In-doped sensors exhibit maximum sensitivity for ethanol, while Fe-doped sensors showed maximum sensitivity for CO gas at its working temperatures. Most importantly, both of these sensors exhibited faster response time of the order of 1-2 s and short recovery time of the order of 15-25 s. Increase of texture coefficient of less dense (200) plane and reduction in band gap upon doping is found to have influence on better sensitivity. © 2014 Elsevier Ltd and Techna Group S.r.l.

For the first time, a new facile approach based on simple and inexpensive chemical spray pyrolysis (CSP) technique is used to deposit Tungsten (W) doped nanocrystalline SnO2 thin films. The textural, optical, structural and sensing properties are investigated by GAXRD, UV spectroscopy, FESEM, AFM, and home-built sensing setup. The gas sensing results indicate that, as compared to pure SnO2, 1 wt % W-doping improves sensitivity along with better response (<2 s) and recovery time (<25 s) toward NO2 gas at operating temperatures of ∼225°C. The optimal composition of 1 wt % W-doped films exhibit lowest crystallite size of the order of ∼8-10 nm with reduced energy band gap and large roughness values of 3.82 eV and 3.01 nm, respectively. Reduction in texture coefficient along highly dense (110) planes with concomitant increase along loosely packed (200) planes is found to have prominent effect on gas sensing properties of W-doped films. © 2015 American Chemical Society.

With the utmost application of wireless network and internet has actuated substantial demands for information security and data concealment. However, wireless systems are more susceptible to illegitimate access and eavesdropping. RC5 has a variable parameters of word size, length of secret key and number of rounds. Ronald Rivest suggested the RC5 algorithm with 12 numbers of rounds for better encryption. In this paper, the proposed work is that if the value for the rounds in RC5 be a prime number then the security level of the cipher is more, as compared to the higher value of rounds up to next prime number. By the National Institute of Standards and Technology (NIST) suite, different tests of RC5 algorithm are performed having same data length and key but for different number of rounds and the result for prime number of round is equated with composite number of rounds and result obtained justify that RC5 for prime number of rounds provide better security level than a result drawn by a composite number of round. © 2014 IEEE.
