Abstract

Electron-electron interactions (EEIs) in 2D van der Waals structures is one of the topics with high current interest in physics. We report the observation of a negative parabolic magnetoresistance (MR) in multilayer 2D semiconductor InSe beyond the low-field weak localization/antilocalization regime, and provide evidence for the EEI origin of this MR behavior. Further, we analyze this negative parabolic MR and other observed quantum transport signatures of EEIs (temperature dependent conductance and Hall coefficient) within the framework of Fermi liquid theory and extract the gate voltage tunable Fermi liquid parameter $F_0^\sigma$ which quantifies the electron spin-exchange interaction strength.

Abstract

An investigation was performed to characterize 25 indigenous Quality Protein Maize (QPM) inbred lines for several morphological traits to study the level of genetic diversity present in the inbreds by utilizing morphological characters and microsatellite markers. On the basis of morphological traits by adopting D2 statistics and Tocher’s method of clustering all the studied inbred lines were clustered into seven clusters and by using molecular markers, based on Jaccard’s similarity coefficient, these were clustered into five clusters. The inbred lines MTCA 1, MTCA 2, MTCA 8, MTCA 6, and MTCA 11, were grouped together, indicating that these inbred lines of maize were closely related to one another in terms of morphological and molecular characterization. Out of the total primers studied, five were observed with more than 0.5 PIC value. SSR primers utilized for the molecular characterization of inbred lines with the mean PIC value of 0.543, were quite informative. A total of 41 alleles were observed with an allele count ranging from 2-5 per locus. The 13 SSR primer pairs used for estimation yielded a total of four unique alleles, with a mean of 0.31 unique alleles per primer. The similarity coefficient estimates for pairs of individuals varied from 0.000 to 1.00. Among the pair-wise combinations of entries evaluated, the magnitude of the similarity coefficient between MTCA 11 and MTCA 10 (1.00) was the highest. However, the molecular data and the cluster diagram based on morphological data were at odds which may be due to the enormous genome size of a cross-pollinated crop like maize.

33. Doubly Fed Induction Generator: Grid Integration and Performance Analysis

Subjects

Abstract

Renewable energy sources are emerging to replace conventional energy sources in the energy mix as a result of the growing demand for power and the constraints of existing energy sources. With technological advancements, wind energy has become a promising secondary energy source, resulting in the proliferation of wind farms around the globe to bolster traditional energy systems. This has led to a rapid increase in the incorporation of wind power into the power grid, emphasizing the need to understand its effects on the system's parameters. A range of generators, including DFIG, SG, and SCIG, are used to generate wind power. Due to benefits of separate control over true and wattless power, variable speed operation and maximum power tracking, a DFIG based wind turbine became a favourite choice for power utilities.

35. Tuning Rashba Spin-Orbit Coupling in Gated Multilayer InSe

Abstract

Manipulating the electron spin with the aid of spin-orbit coupling (SOC) is an indispensable element of spintronics. Electrostatically gating a material with strong SOC results in an effective magnetic field which can in turn be used to govern the electron spin. In this work, we report the existence and electrostatic tunability of Rashba SOC in multilayer InSe. We observed a gate-voltage-tuned crossover from weak localization (WL) to weak antilocalization (WAL) effect in quantum transport studies of InSe, which suggests an increasing SOC strength. Quantitative analyses of magneto-transport studies and energy band diagram calculations provide strong evidence for the predominance of Rashba SOC in electrostatically gated InSe. Furthermore, we attribute the tendency of the SOC strength to saturate at high gate voltages to the increased electronic density of states-induced saturation of the electric field experienced by the electrons in the InSe layer. This explanation of nonlinear gate voltage control of Rashba SOC can be generalized to other electrostatically gated semiconductor nanomaterials in which a similar tendency of spin-orbit length saturation was observed (e.g. nanowire field effect transistors), and is thus of broad implications in spintronics. Identifying and controlling the Rashba SOC in InSe may serve pivotally in devising III-VI semiconductor-based spintronic devices in the future., Comment: 7 pages, 5 figures

45. A Novel Similarity Measure for Intrusion Detection using Gaussian Function

Author

Subjects
Computer Science - Cryptography and Security
Abstract

In this paper the major objective is to design and analyze the suitability of Gaussian similarity measure for intrusion detection. The objective is to use this as a distance measure to find the distance between any two data samples of training set such as DARPA Data Set, KDD Data Set. This major objective is to use this measure as a distance metric when applying k- means algorithm. The novelty of this approach is making use of the proposed distance function as part of k-means algorithm so as to obtain disjoint clusters. This is followed by a case study, which demonstrates the process of Intrusion Detection. The proposed similarity has fixed upper and lower bounds. The proposed similarity measure satisfies all properties of a typical similarity measure., Comment: 11 Pages, SCI Indexed Journal, REVISTA TECNICA DE LA FACULTAD DE INGENIERIA UNIVERSIDAD DEL ZULIA

Abstract

Graphene-like two-dimensional (2D) materials, not only are interesting for their exotic electronic structure and fundamental electronic transport or optical properties but also, hold promises for device miniaturization down to atomic thickness. As one material belonging to this category, InSe is not only a promising candidate for optoelectronic devices but also has potential for ultrathin field effect transistor (FET) with high mobility transport. In this work, various substrates such as PMMA, bare silicon oxide, passivated silicon oxide, and silicon nitride were used to fabricate multi-layer InSe FET devices. Through back gating and Hall measurement in four-probe configuration, the devices' field effect mobility and intrinsic Hall mobility were extracted at various temperatures to study the material's intrinsic transport behavior and the effect of dielectric substrate. The sample's field effect and Hall mobilities over the range of 77-300K fall in the range of 0.1-2.0$\times$10$^3$ cm$^2$/Vs, which are comparable or better than the state of the art FETs made of 2D transition metal-dichalcogenides., Comment: Nano Letters, in press
