Comparison of Atomic Level Simulation Studies of MOSFETs Containing Silica and Lantana Nanooxide Layers

The intense downscaling of a Metal Oxide Semiconductor Field Effect Transistor (MOSFET) to nano range for improving the device performance requires a high-k dielectric material instead of conventional silica (SiO2) as to avoid Quantum Mechanical Tunneling towards the gate terminal which leads to unnecessary gate current. Out of all the rare earth oxide materials, since lanthana (La2O3) has significantly high dielectric constant (k) and bandgap, we’ve chosen it as oxide layer for one of the MOSFETs. In this work, we simulated two MOSFETs – one with nano SiO2 oxide layer and other with nano La2O3 oxide layer in the atomic level to analyze and compare the transmission spectra, I-V characteristics and Channel conductance of both the MOSFETs.

Integrated Multiple Features for Tumor Image Retrieval Using Classifier and Feedback Methods

AbstractThe content based image retrieval method greatly assists in retrieving medical images close to the query image from a large database basing on their visual features. This paper presents an effective approach in which the region of the object is extracted with the help of multiple features ignoring the background of the object by employing edge following segmentation method followed by extracting texture and shape characteristics of the images. The former is extracted with the help of Steerable filter at different orientations and radial Chebyshev moments are used for extracting the later. Initially the images similar to the query image are extracted from a large group of medical images. Then the search is by accelerating the retrieval process with the help of Support Vector Machine (SVM) classifier. The performance of the retrieval system is enhanced by adapting the subjective feedback method. The experimental results show that the proposed region based multiple features and integrated with classifier and subjective feedback method yields better results than classical retrieval systems

Influence of particle size and fluorination ratio of CFₓ precursor compounds on the electrochemical performance of C-FeF₂ nanocomposites for reversible lithium storage

Systematical studies of the electrochemical performance of CFx-derived carbon–FeF2 nanocomposites for reversible lithium storage are presented. The conversion cathode materials were synthesized by a simple one-pot synthesis, which enables a reactive intercalation of nanoscale Fe particles in a CFx matrix, and the reaction of these components to an electrically conductive C–FeF2 compound. The pretreatment and the structure of the utilized CFx precursors play a crucial role in the synthesis and influence the electrochemical behavior of the conversion cathode material. The particle size of the CFx precursor particles was varied by ball milling as well as by choosing different C/F ratios. The investigations led to optimized C–FeF2 conversion cathode materials that showed specific capacities of 436 mAh/g at 40 °C after 25 cycles. The composites were characterized by Raman spectroscopy, X-Ray diffraction measurements, electron energy loss spectroscopy and TEM measurements. The electrochemical performances of the materials were tested by galvanostatic measurements

VOCl as a Cathode for Rechargeable Chloride Ion Batteries

A novel room temperature rechargeable battery with VOCl cathode, lithium anode, and chloride ion transporting liquid electrolyte is described. The cell is based on the reversible transfer of chloride ions between the two electrodes. The VOCl cathode delivered an initial discharge capacity of 189 mAh g−1. A reversible capacity of 113 mAh g−1 was retained even after 100 cycles when cycled at a high current density of 522 mA g−1. Such high cycling stability was achieved in chloride ion batteries for the first time, demonstrating the practicality of the system beyond a proof of concept model. The electrochemical reaction mechanism of the VOCl electrode in the chloride ion cell was investigated in detail by ex situ X-ray diffraction (XRD), infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The results confirm reversible deintercalation–intercalation of chloride ions in the VOCl electrode

Isolation and physico-chemical characterization of <em>Butea parviflora</em> seed oil

The seeds of <em>Butea parviflora</em> were investigated for oil extraction and the oil was studied for complete physico-chemical properties. The fatty acid profile of the seed oil showed oleic acid (18:1) at 27.5%, linoleic acid (18:2) at 26.4%, palmitic acid (16:0) at 16.1% and behenic acid (22:0) at 14.1% as the major fatty acids. The physico-chemical characteristics of the seed oil were studied for parameters such as free fatty acids (0.71%), iodine value (76.2 g/100g), peroxide value (5.95 ppm), saponification value (177.32 mg KOH/g), unsaponifiable matter (0.82%), phosphorous content (197 ppm), triglyceride analysis, tocols, specific gravity and refractive index following standard procedures.<br><br>Se ha estudiado la extracción de aceite de semillas de <em>Butea parviflora</em> así como las características físico-químicas completas del aceite.

Dataset associated with “An in-frame deletion mutation in the degron tail of auxin co-receptor IAA2 confers resistance to the herbicide 2,4-D in Sisymbrium orientale”

Output files from protein docking analysis of the wild-type IAA2 protein and the mutant IAA2 version containing a nine amino acid deletion. These residues were used as docking parameters in HADDOCK 2.4 (https://wenmr.science.uu.nl/haddock2.4/). Docking calculations were performed under expert level, deactivating the DNA/RNA functions and activating the Surface Contact Restrains to enforce contact between the molecules. Degron residues KNNN of SoIAA2 were assigned semiflexible properties during docking whereas the shorter connection in SoIAA2Δ9 was not allowed to be flexible to preserve the structural integrity of PB1. The binding affinities of the SoIAA2/TIR1 and SoIAA2Δ9/TIR1 biological complexes were calculated using PRODIGY (https://bianca.science.uu.nl/prodigy/) for all top 4 poses from the best HADDOCK clusters. Plots are in .html format and protein models are in .pdb format. Files are in TGZ after gzip compression.The natural auxin indole-3-acetic acid (IAA) is a key regulator of many aspects of plant growth and development. Synthetic auxin herbicides such as 2,4-D mimic the effects of IAA by inducing strong auxinic signaling responses in plants. To determine the mechanism of 2,4-D resistance in a Sisymbrium orientale (Indian hedge mustard) weed population, we performed a transcriptome analysis of 2,4-D-resistant (R) and -susceptible (S) genotypes that revealed an in-frame 27-nucleotide deletion removing 9 amino acids in the degron tail (DT) of the auxin co-receptor Aux/IAA2 (SoIAA2). The deletion allele co-segregated with 2,4-D resistance in recombinant inbred lines. Further, this deletion was also detected in several 2,4-D resistant field populations of this species. Arabidopsis transgenic lines expressing the SoIAA2 mutant allele were resistant to 2,4-D and dicamba. The IAA2-DT deletion reduced binding to TIR1 in vitro with both natural and synthetic auxins, causing reduced association and increased dissociation rates. This novel mechanism of synthetic auxin herbicide resistance assigns a new in planta function to the DT region of this Aux/IAA co-receptor for its role in synthetic auxin binding kinetics and reveals a potential biotechnological approach to produce synthetic auxin resistant crops using gene editing.This work was supported in part by funding from Dow AgroSciences, by the Grains Research and Development Corporation – Australian Government, grant UA00158, the Brazilian governmental scholarship from the National Council for Scientific and Technological Development (CNPq - 207387/2014-1) to M.R.A.F., and by the EU MSCA-IF project CrysPINs (792329) in support of M.F.K.
