Memristive Behavior and Ideal Memristor of 1T Phase MoS2 Nanosheets.
Venue: Nano letters

Memristor, which had been predicted a long time ago (Chua, L. O. ) was recently invented (Strukov, D. B. et al.  2008, 453, 80) The introduction of a memristor is expected to open a new era for nonvolatile memory storage, neuromorphic computing, digital logic, and analog circuit. Furthermore, several breakthroughs were made for memristive phenomena and transistors with single layer MoS2 (Sangwan, V. K. et al. . van der Zande, A. M. et al.  2013, 12, 554. Liu, H. et al. ACS Nano 2014, 8, 1031. Bessonov, A. A. et al.  2015, 14, 199. Yuan, J. et al.  Herein, we demonstrate that 2H phase of bulk MoS2 possessed an ohmic feature, whereas 1T phase of exfoliated MoS2 nanosheets exhibited a unique memristive behavior due to voltage dependent resistance change. Furthermore, an ideal odd symmetric memristor with odd symmetric I V characteristics was successfully fabricated by the 1T phase MoS2 nanosheets via combining two asymmetric switches antiserially.

The Use of Price Waterfall Model (PWM) in Logistics

The purpose of the work is to present the capabilities achievable by implementing the Price Waterfall model (PWm) for logistic enterprises. An Innovative Logistic Company (ILC) should, as far as possible, exploit the potential of information technologies delivering data for further processing. The data managed by a Logistic Information System may be used to streamline a pricing process in the sector of logistic services. The PWm was chosen because its linear structure coincides with the linear form of equations of logistic costs' structure. The transaction data processed by a Decision Support System (DSS) based on the PWm allows to make an optimum price decision in a negotiation process considering the parameters of the current price strategy.
IMPLEMENTING DESIGN INTO INSTRUCTION: INTERSECTIONS BETWEEN THE WATERFALL MODEL AND ADDIE MODEL

Instructional design and software design, while two different fields, have many commonalities and finding intersections between the two fields is of great importance to instructional designers, subject matter experts, and ultimately, the educators who use their deliverables. Many instructional designers work on large projects, which in certain circumstances; will include the creation of new learning software. This paper suggests that combining the Waterfall software design model, with the ADDIE instructional Design model, could create a more collaborative process between software designers and instructional designers. In this newly proposed design model, a combination of features of the two previous models allows for a seamless step by step design process.
W Band MMIC PA With Ultrahigh Power Density in 100 nm AlGaN/GaN Technology
Venue: IEEE Transactions on Electron Devices

A three stage W band GaN monolithic microwave integrated circuit power amplifier (MMIC PA) is reported. Electron beam lithography has been employed to define a 100 nm T shaped gate on the AlGaN/GaN HEMT structure with ultrahigh aluminum content. The MMIC PA offers a peak small signal gain of 16.7 dB in the 90 97 GHz bandwidth. Moreover, it achieves a peak 1.66 W (32.2 dBm) output power at 93 GHz in a continuous wave mode, with an associated power added efficiency of 21% and an associated power gain of 13.7 dB. Most notably, the peak power density is 3.46 W/mm with a 480 mm wide output stage, which exceeds 3 W/mm in AlGaN/GaN HEMT at W band for the first time.
High frequency GaN HEMTs for RF MMIC applications
Venue: 2016 IEEE International Electron Devices Meeting (IEDM)

We provide an overview of key challenges and technical breakthroughs that led to development of highly scaled GaN HEMT's having ft 400 GHz and fmax 550 GHz and the corresponding IC process. These highly scaled GaN devices have 5 times higher breakdown voltage than transistors with similar high frequency RF power gain in other semiconductor systems (Si, SiGe, InP, GaAs) We also report performance of the first generation of MMIC power amplifiers (PAs) that utilize these highly scaled devices. The power added efficiency (PAE) of 59% measured at a frequency of 32 GHz, bias of 3 V and output power of 24.3 dBm of the first generation Ka band MMIC PAs that were built using these highly scaled GaN devices, represent a significant improvement in PAE over values reported for other semiconductor technologies at this frequency band as well as for Ka band MMICs built in lower frequency GaN nodes. Presented data suggest that highly scaled GaN transistors are excellent candidates for MMIC PAs for next generation 28 GHz, 39 GHz, and higher frequency 5G mobile bands, because they would greatly extend battery lifetime in mobile handsets, due to their superior PAE compared to competing semiconductor technologies.

Nanocomposite hydrogels of barium ion crosslinked alginate/carboxymethyl cellulose (CMC) with encapulation of TiO 2 NPs were synthesized sucessfully using dissipative convective method followed by freeze drying procedure. As prepared composite hydrogels were charecterized by different techniques such as Fourier Transform Infrared spectroscopy (FT IR) Powder X ray diffraction (PXRD) UV Diffuse reflectance spectroscopy (UV DRS) BET Surface area study, Scanning Electron Microscopy with Energy Dispersive X ray analysis (SEM EDAX) Transmission Electron Microscopy (TEM) and mechanical strength study. Ba/Alg/CMC/TiO2 composite hydrogels exhibited excellent photocatalytic activity towards CR under direct solar light irradiation with pseudo first order kinetics. The recycling ability of Ba/Alg/CMC/TiO2 composite hydrogels confirms that photocatalyst is highly photostable.
Visible light driven efficient photocatalytic degradation of Congo red dye catalyzed by hierarchical CuS Bi2CuxW1 xO6 2x nanocomposite system

A series of CuS Bi2CuxW1 xO6 2x nanocomposite materials were prepared and evaluated as photocatalyst for degradation of Congo red dye from aqueous sources. The Bi2WO6 (BT) nanoparticles were synthesized by amorphous citrate process. The CuS nanomaterials were dispersed over the BT matrix using hydrothermal route. The composite materials (CuSBT) were characterized using XRD, FESEM, TEM, XPS, UV Vis DRS, PL, sorptometric and FTIR techniques. XRD study indicated the existence of hexagonal covellite CuS and orthorhombic Russellite BT phase. During hydrothermal treatment, the Cu2+ ions substituted for the W6+ ions in the BT lattice to form a substitutional solid solution (Bi2CuxW1 xO6 2x) The composite materials contain CuS nanorods and BT nanosheets. During hydrothermal treatment, significant morphological reorganization of the BT phase took place leading to the formation of flower like hierarchical nanostructures. The CuSBT materials possess characteristic features of a type II heterojunction exhibiting narrow band gap, enhanced visible light absorption and efficient charge separation properties. The CuSBT materials were evaluated as visible light active photocatalyst for complete degradation of Congo red dye using H2O2 as oxidant. The CuSBT materials exhibited higher apparent rate constant (Kapp) and greater efficiency for Congo red degradation compared to pure BT material. The photocatalytic protocol developed in this work was significant in terms of minimum and efficient use of catalyst and oxidant, less irradiation time and its applicability for aqueous effluents containing higher concentration of the dye.

Environmental based smart clustering for mobile networks.

Nowadays there is a plethora of wireless handsets in the market such as smartphones, tablets, laptops and wearable devices, that together with the the future emerging scenarios on vehicle to vehicle communications and smart city infrastructure will populate urban environments with a broad diversity of multi standard wireless devices. This increase in the density and diversity of mobile devices have been the driver for collaborative protocols that can deliver effective communications. Cooperation is a technology that has the potential to provide energy efficient and scalable communications, where nodes play an important role to coordinate local traffic and act as gateways to the core network. Despite the diverse power requirements of multi standard wireless interfaces and the different channel characteristics, support for energy efficient communications where relay nodes can be selected with lower energy requirements or with higher order modulation opportunities, is still expected. In this framework, clustering is a widely accepted technique that allows nodes create and join virtual cooperative groups, and to select a clusterhead that can provide a high speed and energy efficient backhaul link to the mobile network. The vast majority of existing clustering techniques assume that the collection of nodes that form a cluster are either static or have very low relative velocity. However, in practice nodes or devices are constantly on the move providing the impetus for mobility aware clustering techniques that elect a subset of nodes with a common mobility pattern. In this context, mobility aware clustering, based on geolocation, is an active field of research due to the increasing interest of vehicular communication technology. However, clustering has a wide range of applications where GPS information is not always available. This requires a new design of clustering algorithms that do not depend on GPS coordinates. This challenge has fostered a new vision of clustering based on cognition, where nodes form mobile clusters that can adapt on demand to the scenario characteristics. This thesis investigates cluster formation exploiting the notion of wisdom of crowds, where the nodes are aware of the surrounding mobility patterns and can adapt the cluster formation strategy to suit the current mobility trends. Moreover, this thesis also caters for a novel analytical model for cluster lifetime that is used to validate our simulation results. Another dimension to the clustering problem is how to exploit available spectral opportunities for cluster formation in a secure manner. Cognitive radio, and more concretely cooperative spectrum sensing is evaluated in this thesis as a solution for data channel assignment in mobile clusters. In this scenario, we focus on the security concerns of cooperative spectrum sensing. Namely, we address spectrum sensing data falsification and incumbent emulation attacks, and propose an energy efficient security mechanisms based on lightweight cryptography to address these threats.
A decision framework for an adaptive behavioral intervention for physical activity using hybrid model predictive control
Venue: 2016 American Control Conference (ACC)

Physical inactivity is a major contributor to morbidity and mortality worldwide. Many physical activity behavioral interventions at present have shown limited success addressing the problem from a long term perspective that includes maintenance. This paper proposes the design of a decision algorithm for a mobile and wireless health (mHealth) adaptive intervention that is based on control engineering concepts. The design process relies on a behavioral dynamical model based on Social Cognitive Theory (SCT) with a controller formulation based on hybrid model predictive control (HMPC) being used to implement the decision scheme. The discrete and logical features of HMPC coincide naturally with the categorical nature of the intervention components and the logical decisions that are particular to an intervention for physical activity. The intervention incorporates an online controller reconfiguration mode that applies changes in the penalty weights to accomplish the transition between the behavioral initiation and maintenance training stages. Simulation results are presented to illustrate the performance of the controller using a hypothetical model for physical activity interventions, under realistic conditions.
Gene targeting and transgene stacking using intra genomic homologous recombination in plants
Venue: Plant Methods

Modern agriculture has created a demand for plant biotechnology products that provide durable resistance to insect pests, tolerance of herbicide applications for weed control, and agronomic traits tailored for specific geographies. These transgenic trait products require a modular and sequential multigene stacking platform that is supported by precise genome engineering technology. Designed nucleases have emerged as potent tools for creating targeted DNA double strand breaks (DSBs) Exogenously supplied donor DNA can repair the targeted DSB by a process known as gene targeting (GT) resulting in a desired modification of the target genome. The potential of GT technology has not been fully realized for trait deployment in agriculture, mainly because of inefficient transformation and plant regeneration systems in a majority of crop plants and genotypes. This challenge of transgene stacking in plants could be overcome by Intra Genomic Homologous Recombination (IGHR) that converts independently segregating unlinked donor and target transgenic loci into a genetically linked molecular stack. The method requires stable integration of the donor DNA into the plant genome followed by intra genomic mobilization. IGHR complements conventional breeding with genetic transformation and designed nucleases to provide a flexible transgene stacking and trait deployment platform.
Performance comparison and device analysis Between Si IGBT and SiC MOSFET
Venue: 2016 IEEE Transportation Electrification Conference and Expo (ITEC)

The paper presents the characteristics of the latest commercial 1200V 300A SiC MOSFET module and compares it's performance with Si IGBT with the same rating using experimental results and the saber software environment. Our SiC MOSFET model in SABER gives accurate results across a wide range of temperatures. The results show that the 1200V SiC MOSFET has faster switching speed and significantly less switching loss compared to the Si IGBT. Moreover, the Si IGBT switching loss will increase significantly for higher operation temperature, while the SiC MOSFET switching loss has little variation over different temperatures. This paper will also investigates the stray inductance effect on the gate, drain, and source side and verifies its performance with Si IGBT. The double pulse test circuit has been implemented in SABER to simulate the dynamic losses and a brief review of the various applications for automotive industry of the SiC MOSFET has been also presented in the paper.
Efficacy of Montessori and traditional method of education on self concept development of children

*Corresponding Author E mail: kumarpsy123@rediffmail.com Tel. +91 9844935744 Montessori is a method of education started by Maria Montessori in 1903 for the educationally backward children; after finding its efficacy on them it was thought that it even well suits for the normal children. It became very popular throughout the world in the 20th century and has been implemented both in private and public institutions. Based on certain principles it is evident in many of the researches conducted so far that the Montessori education is conducive for the overall development in social, emotional and cognitive components of children. With this background the present study was conducted to explore the effect of Montessori education on social development in terms of self concept of the children as compared to the children of traditional method of education. Using descriptive and parametric tests for the obtained data it was found that the Montessori children have very high self concept than the traditional children. Percentage result shows that the traditional children's self concept ranges from low to high category and the Montessori children's self concept ranges from high and very high, which indicated marked difference between them in self concept. According to independent samples t test results there was a statistical significant difference between the Montessori children group and the traditional children group, the Montessori children are found to have higher self concept.
Reviewing Literature on Employee Wellness Practices

Employee wellness programmes (EWP) can be termed as introduction of healthcare interventions which are targeted towards minimising health risk factors and encourage employees to adopt healthier way of living. The objective of the study was to discern the history of employee wellness practices and review literature pertaining to same. The paper reviews the origin of the concept of wellness and development of this approach at workplace. The study took into account the various models of wellness, types and levels of wellness interventions being undertaken, and the successful elements of certain programmes which have proved to be beneficial to the employee as well as employer. Analysis of literature and available data suggest that with rising lifestyle changes and diseases, the importance of employee wellness practices have grown in scope and coverage over the years. The range of EWP varies from organisation to organisation and yet to become a strategic HR initiative. The paper suggests the theoretical background required for better understanding of these practices. With employers practicing various components of employee wellness programmes, detailed information related to benchmark studies covering its types, strategies and evaluation pattern need to be studied.
How antigen specificity directs regulatory T cell function: self, foreign and engineered specificity
Venue: HLA

Regulatory T cells (Tregs) are a suppressive subset of T cells that have important roles in maintaining self tolerance and preventing immunopathology. The T cell receptor (TCR) and its antigen specificity play a dominant role in the differentiation of cells to a Treg fate, either in the thymus or in the periphery. This review focuses on the effects of the TCR and its antigen specificity on Treg biology. The role of Tregs with specificity for self antigen has primarily been studied in the context of autoimmune disease, although recent studies have focused on their role in steady state conditions. The role of Tregs that are specific for pathogens, dietary antigens and allergens is much less studied, although recent data suggest a significant and previously underappreciated role for Tregs during memory responses to a wide range of foreign antigens. The development of TCR or chimeric antigen receptor (CAR) transduced T cells means we are now able to engineer Tregs with disease relevant antigen specificities, paving the way for ensuring specificity with Treg based therapies. Understanding the role that antigens play in driving the generation and function of Tregs is critical for defining the pathophysiology of many immune mediated diseases, and developing new therapeutic interventions.
An MHC restricted antibody based chimeric antigen receptor requires TCR like affinity to maintain antigen specificity
Venue: Molecular therapy oncolytics

Chimeric antigen receptors (CARs) are synthetic receptors that usually redirect T cells to surface antigens independent of human leukocyte antigen (HLA) Here, we investigated a T cell receptor like CAR based on an antibody that recognizes HLA A*0201 presenting a peptide epitope derived from the cancer testis antigen NY ESO 1. We hypothesized that this CAR would efficiently redirect transduced T cells in an HLA restricted, antigen specific manner. However, we found that despite the specificity of the soluble Fab, the same antibody in the form of a CAR caused moderate lysis of HLA A2 expressing targets independent of antigen owing to T cell avidity. We hypothesized that lowering the affinity of the CAR for HLA A2 would improve its specificity. We undertook a rational approach of mutating residues that, in the crystal structure, were predicted to stabilize binding to HLA A2. We found that one mutation (DN) lowered the affinity of the Fab to T cell receptor range and restored the epitope specificity of the CAR. DN CAR T cells lysed native tumor targets in vitro, and, in a xenogeneic mouse model implanted with two human melanoma lines (A2+/NYESO+ and A2+/NYESO DN CAR T cells specifically migrated to, and delayed progression of, only the HLA A2+/NY ESO 1+ melanoma. Thus, although maintaining MHC restricted antigen specificity required T cell receptor like affinity that decreased potency, there is exciting potential for CARs to expand their repertoire to include a broad range of intracellular antigens.
