Non-Volatile Resistive Switching in Graphene Oxide Thin Films

The semiconductor industry has long been seeking a high-density, high-speed, and lowpower memory technology that retains its data even when the power is interrupted (Meijer, 2008). Though static random access memory (SRAM) and dynamic random access memory (DRAM) are very fast, both of them are volatile, which is a huge disadvantage, costing energy and additional periphery circuitry. Si-based Flash memory devices represent the most prominent nonvolatile data memory (NVM) because of their high density and low fabrication costs. However, Flash suffers from low endurance, low write speed, and high voltages required for the write operations. In addition, further scaling, i.e., a continuation in increasing the density of Flash is expected to run into physical limits in the near future. Ferroelectric random access memory (FeRAM) and magnetoresistive random access memory (MRAM) cover niche markets for special applications. One reason among several others is that FeRAM as well as conventional MRAM exhibit technological and inherent problems in the scalability, i.e., in achieving the same density as Flash today. In this circumstance, a renewed nonvolatile memory concept called resistance-switching random access memory (RRAM), which is based on resistance change modulated by electrical stimulus, has recently inspired scientific and commercial interests due to its high operation speed, high scalability, and multibit storage potential (Beck et al., 2000; Lu & Lieber, 2007; Dong et al., 2008). The reading of resistance states is nondestructive, and the memory devices can be operated without transistors in every cell (Lee et al., 2007; Waser & Aono, 2007), thus making a cross-bar structure feasible. A large variety of solid-state materials have been found to show these resistive switching characteristics, including solid electrolytes such as GeSe and Ag2S (Waser & Aono, 2007), perovskites such as SrZrO3 (Beck et al., 2000), Pr0.7Ca0. 3MnO3 (Liu et al., 2000; Odagawa et al., 2004; Liao et al., 2009), and BiFeO3 (Yang et al., 2009; Yin et al., 2010; Li et al., 2010), binary transition metal oxides such as NiO (Seo et al., 2004; Kim et al., 2006; Son & Shin, 2008), TiO2 (Kim et al., 2007; Jeong et al., 2009; Kwon et al., 2010), ZrO2 (Wu et al., 2007; Guan et al., 2008; Liu et al., 2009), and ZnO (Chang et al., 2008; Kim et al., 2009; Yang et al., 2009), organic materials (Stewart et al., 2004), amorphous silicon (a-Si) (Jo and Lu, 2008; Jo et al., 2009), and amorphous carbon (a-C) (Sinitskii & Tour, 2009; Zhuge et al., 2010). In last decades, carbon-based materials have been studied intensively as a potential candidate to overcome the scientific and technological limitations of traditional
Assessment of genetic diversity using RAPD analysis in a germplasm collection of sea buckthorn

Random amplified polymorphic DNA (RAPD) markers were used to characterize a part of a sea buckthorn gene bank collected for plant breeding purposes. Molecular markers were generated in 55 cultivars and accessions, representing five subspecies of Hippophae rhamnoides L. and intraspecific hybrids between different subspecies. Sixty-three markers were used to generate a Dice's similarity coefficient matrix of pairwise comparisons between individual RAPD profiles. Cluster (UPGMA) and principal co-ordinate analyses, based on this matrix, revealed clustering of plants into groups which generally correspond to their taxonomic classification or geographic origin. The analysis of molecular variance (AMOVA) was found useful for estimating components of genetic variation between and within taxonomic and geographic groups of accessions and cultivars. Whereas both alternatives for grouping the material (taxonomic or geographic origin) resulted in significant between-group variation, the major part of molecular variance (approximately 75%) was still attributed to variation within groups. We conclude that the RAPD analysis is useful for clarification of taxonomic and geographic origin of accessions and cultivars of sea buckthorn.
Second Workshop on Exploratory Search and Interactive Data Analytics ( ESIDA )

This is the second edition of the Workshop on Exploratory Search and Interactive Data Analytics (ESIDA). This series of workshops emerged as a response to the growing interest in developing new methods and systems that allow users to interactively explore large volumes of data, such as documents, multimedia or specialised collections, such as biomedical datasets. There are various approaches to supporting users in this interactive environment ranging from the development of new algorithms through visualisation methods to analysing users’ search patterns. The overarching goal of ESIDA is to bring together researchers working in areas that span across multiple facets of exploratory search and data analytics to discuss and outline research challenges for this novel area.
Inflame my plaque (inflammation and atherosclerosis)

Monocytes are a key cell type responsible for the generation of atherosclerosis. Monocytes/macrophages also play key roles in plaque growth and plaque instability. In contrast, recent research has demonstrated that macrophages can also suppress inflammation and promote healing and fibrosis. Some of this complexity relates to the presence of different macrophage subtypes that are induced and activated by different stimuli within the plaque. Macrophage functions include lipid uptake and oxidation with resultant foam cell formation, release of pro or anti-inflammatory cytokines, phagocytosis of dead macrophage and vessel wall cells, release of destructive enzymes such as matrix metalloproteinases, and presentation of antigen to immune cells. Each of these functions is likely to be occurring simultaneously in different subtypes within the complex environment of the plaque. While selective manipulation of monocytes/macrophages has clearly demonstrated their proatherogenic role in early plaque development, their role in advanced plaques has been more difficult to elucidate. Nonetheless, switching of a proinflammatory to an anti-inflammatory/reparative phenotype represents an attractive target for therapeutics in atherosclerosis. Heart Metab; 2013;60:5–8
Menadione: Role in cancer prevention and methods of analysis

Menadione (vitamin K3) is a water-insoluble vitamin and an analogue of vitamin K. Its use an anti-cancer drug is increasing day by day. It produces its anti-tumor effect without causing any harm to the normal cells. Various methods have been developed for the analysis of menadione in pure form, pharmaceutical products and biological fluids which includes spectrophotometry, chromatography, potentiometry, colorimetry, electrochemical, chemiluminescenes and polarographic methods. Of all the methods HPLC methods have been found to give more reliable and sensitive results. Fluorimetric methods are more promising as compared to the spectrophotometric methods for the assay of menadione. Certain polarographic methods have been found to give better results for the biological fluids. Chemiluminescence methods can be used for the assay of the vitamin without facing any interference.
Building a Moroccan dialect electronic Dictionary (MDED)

— Even if many resources already exist for Modern Standard Arabic (MSA), the lack of resources is considered as a severe problem that crucially impede the development of natural language processing tools for Arabic dialects in general and particularly for Moroccan dialect (MD). Hence, in order to solve this unfortunate problem, we propose to use resources of MSA and take advantage of the closeness of MSA and its variant MD to make translation between MSA and MD. In this paper, we describe the building of bilingual dictionary MSA versus MD, in order to prepare resources for the sake of creating a machine translation system of the MD. To begin with, we translated manually to MD content of an MSA dictionary, and then we translated to MSA other content of an MD dictionary. At last, we collected from the web the most recent MD words. After some eliminations and manual validation, we obtained 18000 entries in our dictionary.
Thermodynamic stability of phases and transition kinetics under adiabatic conditions

A study of equilibrium states of a thermodynamic system whose evolution is governed not only by the temperature, but also by the ordering field is carried out. It is found that an adiabatically insulated system may have a new type of nonuniform state of equilibrium which is inhomogeneous in temperature. The comparison is made of the stability conditions in isothermal and adiabatic systems. The steady motion of an interface boundary during a first‐order phase transition is investigated. It is shown, that depending upon the values of the diffusion coefficients, different regimes can exist. For small thermal diffusivity, the temperature of the final phase after the exothermal transition can be above the equilibrium point. The kinetic problem is reformulated to a dynamical system, and a numerical procedure to solve the latter is presented. Numerical results are discussed in comparison with analytic ones.
Factors influencing mobile banking adoption in Kurunegala district

Many banks in Sri Lanka are starting to offer banking services through mobile phones. However, not many studies investigate the factors that may help the bankers to design mobile services, which are suitable for and adoptable by bank customers. This study fills this gap and examines a number of factors affecting the mobile banking adoption. Using Diffusion of Innovation as a baseline theory, a convenient sample of 40 actual mobile banking customers was selected from four commercial banks in Kurunegala District. Data are obtained by using self-administrated questionnaire and analyzed with the use of SPSS V 21. It is found that perceived usefulness, perceived risk, and compatibility have impact on M-banking adoption. Contrary to the findings in extant literature, social influences have no significant effect on adoption. The findings of this study will have practical implications for banking industry in Sri Lanka. It is recommended that, commercial banks should demonstrate to their customers the advantage they are bound to have by adopting and using mobile banking over using conservative banking methods. It is also advisable to examine the effects of mobile banking on profitability of commercial banks in Sri Lanka.
Worst Cell Based Pilot Allocation in Massive MIMO Systems

Massive multiple-input multiple-output (MIMO) has been viewed as an advanced technique in future 5G networks. Conventional massive MIMO systems consist of cellular base stations (BS) equipped with a very large number of antennas to simultaneously serve many single-antenna users. Unfortunately, massive MIMO system’s performance is limited by pilot contamination (PC) problem. Conventionally, all users in massive MIMO systems are assigned pilot randomly. In this paper, we propose a pilot allocation algorithm based on a cell with the worst channel quality (WCPA) algorithm to improve the uplink achievable sum rate of the system. Specifically, WCPA exploits the large-scale coefficients of fading channels between the BSs and users. According to the number of available orthogonal pilot sequences, we choose some of the highest inter-cell interfering users and assign each of them a unique pilot sequence if the number of pilot sequences is more than the number of users in a cell. Next, we choose a target cell with the worst channel quality, and gather the highest channel gain user in the target cell and the lowest interfering user in the other cells in the same group in a sequential way by assigning them the same pilot sequence. The simulation results show the outperformance of the proposed algorithm compared to the conventional pilot allocation schemes.
Paraplegia Related Osteoporosis

The World Health Organisation (WHO) created an operational definition of postmenopausal osteoporosis based on a bone mineral density (BMD)-based T-score measurement. The most widely validated technique to measure BMD is dual energy X-ray absorptiometry (DXA), and diagnostic criteria based on the T-score for BMD are a recommended entry criterion for the development of pharmaceutical interventions in osteoporosis. (2) The ranking system of the WHO is commonly used in the literature and in all discussions with respect to bone diseases. According to WHO criteria, the general categories for making a diagnosis are the following: 1) normal: BMD of not less than one standard deviation (SD) than the average young adult (Tscore>-1), 2) osteopenia: BMD between one and 2.5 SD below the average for young adults (-1<T-score<-2.5), 3) osteoporosis: BMD 2.5 SD or more below the average for young adults (Tscore>-2.5) and 4) severe or established osteoporosis: BMD 2.5 SD or more below the average for young adults and the presence of one or more fractures.

DEPARTAMENTO DE ECONOMÍA DOCUMENTO DE TRABAJO “ Income Taxation and Marital Decisions ”

We develop an equilibrium matching model with search frictions in order to analyze the e¤ects that di¤erential tax treatment of married and single individuals have on marriage formation and dissolution. Our main results are the following: (i) although an increase in the ‘marriage tax’ reduces the number of marriages, there is a two-sided search e¤ect that can substantially mitigate its impact on marriage formation and dissolution; (ii) an increase in the ‘marriage tax’ need not make both men and women more reluctant to get married; (iii) the e¤ects of a given change in the di¤erential taxation on marital behavior depend on whether it is implemented via changes in the tax rates that singles face or in the tax rates that married people face; (iv) we compute an example to calculate the size of the two-sided search e¤ect and . nd that large changes in the marriage tax penalty can lead to small changes in the number of marriages and divorces. The example also reveals that the number of divorces can actually increase with a reduction in the ‘marriage tax’.
Understanding BPMN Through Defect Detection Process

: BPMN (Business Process Modelling Notation) diagrams enhance the perception of the business analysts to better understand and analyse the processes of the organizational setting and provide a common communication medium both for business analysts and IT professionals. The changes in the business systems require business analysts to understand the processes and improve them and IT professionals to comprehend and implement these processes as a software system. The main aim of this study is to analyse which type of defects can be detected in a given BPMN diagrams easily by novice users. We believe the results of this study will provide a guide for the educators in teaching, for business analysts and IT professionals in understanding and improving business processes.
Tannin-based Coagulants from Laboratory to Pilot Plant Scales for Coloured Wastewater Treatment

Bark tannin extract from Acacia mearnsii (Mimosa ME) was modified at laboratory and pilot plant scales via the Mannich condensation reaction using formaldehyde and dimethylamine hydrochloride. Several conditions were varied during the modification procedure (heating rate, formaldehyde dosage, and Mannich solution activation time) to evaluate their influence on the shear viscosity and shelf life of the resulting products. It was possible to tune these properties with the reaction conditions. Modified condensed tannins with five distinct shear viscosities (30 cP to 430 cP) were selected to test the colour removal of anionic (Duasyn Direct Red and Acid Black 2) and cationic (Methylene Blue and Crystal Violet) dyes. The performance was monitored by ultraviolet spectroscopy. Colour removal was studied over different pH levels (1 to 14). Good decolouration results (85% to 96% reduction) were obtained with the simultaneous introduction of other additives to the process, which were bentonite and a cationic or anionic polyacrylamide, with minimal dosages of the latter additives. An improvement to decolouration performance with an increase in the biocoagulant viscosity was typically observed. However, for practical applications, modified condensed tannins with a lower viscosity may be preferred because they exhibited a longer shelf life and presented reasonable removal efficiencies.
Vascular Growth in the Fetal Lung

The structure of the lung is truly remarkable. It is primarily composed of three branched tubular networks (the airway, pulmonary artery and vein, bronchial artery and vein) which supply blood and air to the site of gas exchange and which maintain nutrient supply to supporting tissues. This complex interwoven network is packed into a chest cavity with a volume of 6 litres but yet it services a gas-exchange surface area of 130m2, the floor area of a comfortably sized Mediterranean holiday villa! Weibel (1991) tells us that if this surface area were arranged as a balloon it would possess a radius of 3m and a volume of 113,000 litres, more than 18 thousand times the space available in the chest cavity. The process which drives this exceptional packaging involves repeated cycles of ordered branching to create a fractal network of tubules whose core dimensions decrease at a precise and regular rate with each successive branch. This is a high “gain-of–structure” process. In the airway, 23 generations of branching form a conducting tubular network with 17 million branches and a combined length of more than 7km. This provides convective air flow to 480 million alveoli each of which are located along a path length that is no further than 45cm from the external atmosphere. The pulmonary vasculature forms along side the airway but undergoes an additional five generations of branching to form the capillary network that surrounds each alveolus. If you simply assumed that each alveolus (diameter ~200m) was serviced by only one blood vessel you would calculate that the alveolar capillary bed alone runs to nearly 100 km in length. Realistic attempts at modelling this structure in three dimensions suggest that it is, in all probability, between 2 and 6 thousand km long (Muhlfield et al., 2010), illustrating the impressive capacity of fractal branching processes to package colossal structures into ever smaller spaces. The airway and pulmonary vasculature interface with one another at the alveolar bloodgas barrier where oxygen and carbon dioxide diffuse along partial pressure gradients. This extremely thin (0.65m) membrane is composed of cytoplasmic leaflets of type I alveolar epithelial cells and capillary endothelial cells held together with a chicken-wirelike mesh of type IV collagen. Here, a compromise must be met between high surface area, thin-ness and tensile strength to ensure that gas exchange proceeds efficiently from rest-to-work without rupture of the membrane caused by pressure differences across between the alveolar and vascular space. One estimate places the inherent tensile strength of this interface at 0.3MPa (West, 2003) which is close to that of pure type IV collagen
Molecular genetics and Cytogenetics data of 317 patients with de novo acute leukemia

Background/Aims: Cytogenetic and molecular genetics play a pivotal role in treatment of acute leukemias. We prospectively evaluated genetic alterations in Brazilian patients with acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) and their association with clinical and laboratorial data. Methods: Flow cytometry, conventional cytogenetics (CC), FISH, PCR, RT-PCR and sequencing were performed on samples from 161 de novo ALL and 155 AML. Results: Main CC findings in AML were t(15;17) (19.4%), +8 (17.4%), complex karyotype (14.6%), t(8;21) (7.6%); in ALL main CC findings were high hyperdiploidy (18.7%), low hyperdiploidy (9.7%), t(1;19) (9.7%), t(9;22) (8.2%). Frequencies of gene fusions and mutations in AML were PML-RARa 21.9%, RUNX1-RUNX1T1 7.1%, CBFB-MYH11 and MLL-AF9 2.6%, FLT3-ITD 14.2%, NPM1mut 13.6%. In ALL, ETV6-RUNX1 and BCR-ABL were present in 11.5% of the cases, TCF3-PBX1 in 10.8% and MLL-AF1 in 1.5%. Results were discordant between CC and RT-PCR in 3.6% of the cases. PML-RARa was associated with younger age, lower WBC and platelet; FLT3-ITD with higher hemoglobin and WBC; NPM1mut with higher platelet and WBC, older age and normal karyotype. BCR-ABL was associated with higher age; MLL-AF1 with higher WBC and EGIL BI-subtype. Conclusions: The incidence of some aberrations in AML differed from international literature. Discrepancies found between methodologies reinforce the importance of both CC and PCR in the diagnosis of leukemias.
Increased lipid desaturation and ovarian cancer stem cells

Epithelial ovarian cancer is still the most lethal gynecological malignancy (1-3) with an overall 5-year survival rate of <50% (4). This is particularly troubling considering the fact that preclinical research over the last couple of years led to significant advances in our general understanding of cancer biology, which spurred the development of numerous novel anti-cancer drugs.

Removal of Chromium from Aqueous Solution by Custard Apple (Annona Squamosa) Peel Powder as Adsorbent

Chromium has been widely used in various industries like textile, leather, chemical manufacture, metal finishing, paint industry and many other industries. Since hexavalent chromium is a priority toxic, mutagenic and carcinogenic chemical when present in excess, it is very much required to remove chromium from effluents before allowing it to enter any water system or on to land. In the present study, the removal of hexavalent chromium by adsorption on the Custard apple peel powder as adsorbent has been investigated in the batch experiments. The agitation time, the adsorbent size, adsorbent dosage, initial chromium concentration, temperature and the effect of solution pH are studied. The Freundlich model for Cr (VI) adsorption onto Custard apple peel powder is proved to be the best fit followed by Langmuir model and Tempkin model based on high regression coefficient R^2 value. The adsorption behavior is described by a pseudo second order kinetics. The maximum metal uptake is found to be 7.874 mg/g. The morphology on the surface of adsorbents and also the confirmation of chromium binding on adsorbent surface at different stages were obtained by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) analysis. The results obtained in this study illustrate that Custard apple peel powder is expected to be an effective and economically viable adsorbent for hexavalent chromium removal from industrial waste water.
