Modeling and Design of Rectangular Microstrip Patch Antenna with Iso / Anisopropic Substrate Using Neuro-spectral Computation Approach

In this paper, we propose a general design of rectangular microstrip antenna printed on isotropic or anisotropic substrate, based on artificial neural networks (ANN) in conjunction with spectral domain formulation. In the design procedure, syntheses ANN model is used as feed forward network to determine the resonant frequency. Analysis ANN model is used as the reversed of the problem to calculate the antenna dimension for the given resonant frequency, dielectric constant and height of substrate. The electromagnetic knowledge combined with artificial neural network in the analysis and the design of circular antenna to reduce the complexity of the spectral approach and to minimize the CPU time necessary to obtain the numerical results. The results obtained from the neural models are in very good agreement with the experimental results available in the literature.

Australasian ( ACIS ) 2007 Dynamics of Knowledge Leverage in ERP Implementation

This paper reports the results of an in-depth investigation of the knowledge management (KM) activities of an ERP implementation project within a dynamic business setting. Using a case study approach, this research examines the challenges faced by the ERP project team with respect to KM and the effectiveness of KM strategies. In addition to gaining insights into typical KM activities within the ERP project lifecycle, the research reveals that major barriers for effective KM are created by external business changes and the business process life cycle. These changes trigger a chain reaction resulting in the weak performance of key KM activities such as knowledge capture, sharing and retention. The need for a comprehensive array of KM initiatives that are capable of managing such changes by recognizing the dynamics of all three life cycles is highlighted.
Recent Advances in Zika Virus Vaccine Development Sidra

Symbiosis Group Figure 1: Three different mechanisms of ADE (Antibody-dependent enhancement): A-receptors on virus particles bound by cross-reactive antibody get conformational change in structure that results in high affinity with the corresponding receptor on the host cell membrane. The corresponding receptor was not able to recognize the viral receptor before this conformational change. BThe cross-reactive antibody binds to viral and host cell membrane receptors at the same time bringing the viral particle near to the host cell. CThe Fc component of the cross-reactive antibody is recognized by the corresponding receptor on host cell membrane being the predominant mechanism of ADE phenomenon. Transmission
tructure and histochemistry of medicinal species of Solanum audineia

Studies on native medicinal plants strengthen initiatives to preserve the environments where those species naturally occur, many of them already strongly menaced even before their potential to humankind is known. Root and stem barks, leaves, and pericarps samples of Solanum agrarium Sendtn. , S. lycocarpum A. St.-Hil. , S. palinacanthum Dunal, S. paniculatum L. , and S. stipulaceum Roem. & Schult. , species that occur in the Cerrado (Brazililan savanna) were processed according to common light microscopy techniques for structural analysis, and histochemical tests were performed to locate and identify classes of chemical compounds. The distinctive features identified were low concentration of crystal sand in the root and stem, presence of terpene resin in the root, and absence of hypodermis in the leaf, in S. agrarium; bright spots (group of sclereids) in the root, isobilateral mesophyll, thickened cell walls with hemicelluloses and strong aroma in the fruit, in S. lycocarpum; high concentration of crystal sand in the root and stem, ovalshaped limb, presence of isolated crystals in the exocarp, in S. palinacanthum; strong sclerification and rays with great height in the root and stem, in S. paniculatum; and accumulation of soluble protein in the root and stem, presence of conspicuous membranaceous stipules, absence of spiniform trichomes, in S. stipulaceum. This work identifies distinctive structural features, its ecological importance, and determines the distribution of secondary compounds associated with the medicinal properties reported for these species and contributes to the conservation of the natural environments where they occur. © 2015 Sociedade Brasileira de Farmacognosia.

Analysis of serum electrolyte and lipid profile in young Bangladeshi female with Type II Diabetes

Abstract Objective: Type 2 Diabetes Mellitus is one of the most serious and common public health problems and metabolic disorder in both developed and developing countries. Diabetic patient may suffer from imbalanced electrolyte and lipid profile due to complications of diabetes mellitus and the medication they receive. Electrolytes and lipids have noteworthy roles, and changes in their concentrations provide significant signs of disease progression in a number of non-communicable diseases like diabetes. As there is a very few study of electrolyte and lipid profile in young Bangladeshi female diabetic patients, we investigated to identify the status of serum electrolytes and lipid profile with fasting blood glucose levels in type 2 diabetic female subjects with age ranging from 20 to 30. Subjects: Thirty-five female type 2 diabetes mellitus patients and 15 non-diabetic healthy control female volunteers of 20–30 age were recruited to determine serum glucose, electrolytes (Na+, K+, Cl−, and HCO3−), and lipid profiles (total cholesterol, triglyceride, HDL, and LDL). Result: The mean levels of electrolytes except K+ and lipid profile except HDL were found significantly higher (p < 0.001) in comparison with control group. While, there was significant (p < 0.05) decrease in the serum levels of K + and HDL in all diabetics. Conclusion: These results presented some variations from other research having different age and sex. Therefore, it can be concluded that there might have an effect of age and sex differences on lipid and electrolyte profile. This abnormal biochemical profile could be a noteworthy sign of diabetes associated disease and may have great potential as a diagnostic tool in clinical practice.

Timely and accurate national-scale mapping of urban land in China using Defense Meteorological Satellite Program’s Operational Linescan System nighttime stable light data

Abstract Urban land accounts for a small fraction of the Earth’s surface area but rapid increases in urban land have a disproportionate influence on the environment. China is a living laboratory in urbanization and has witnessed fast urban growth in recent decades. The timely and accurate mapping of urban land in China is an urgent and basic issue toward clarifying the urbanization process and revealing its environmental impacts. Nighttime stable light (NSL) data obtained by the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP/OLS) can provide an economical way to map urban land nationwide. However, it is difficult to apply existing methods to accurately extract urban land from DMSP/OLS NSL data covering the entirety of China due to China’s large area and substantial regional variation. A stratified support vector machine (SSVM)-based method used to map the urban land in China in 2008 at a national scale using DMSP/OLS NSL and SPOT normalized difference vegetation index data is presented. The results show that measurement of urban land in China in 2008 using SSVM achieves an average overall accuracy of 90% and an average Kappa of 0.69. The success of this research demonstrates the great potential of SSVM for clarifying the urbanization process in continental and global research.
Long-Term Consequences of Access to Well-Child Visits

A growing literature documents the positive long-term effects of policy-induced improvements in early-life health and nutrition. However, there is still scarce evidence on early-life health programs targeting a large share of the population and the role of such programs in increasing intergenerational mobility. This paper uses the rollout of mother and child health care centers in Norway, which commenced in the 1930s, to study the long-term consequences of increasing access to well-child visits. These well-child visits included a physical examination and the provision of information about adequate infant nutrition. Our results indicate that access to mother and child health care centers had a positive effect on education and earnings: access in the first year of life increased the completed years of schooling by 0.15 years and earnings by two percent. The effects were stronger for children from a low socioeconomic background. In addition, we find that individuals suffer from fewer health risks at age 40 and positive effects on adult height, which support the fact that better nutrition within the first year of life is the likely mechanism behind our findings. While there is increasing knowledge on the benefits of various types of early childhood programs, the costs are often neglected, making it hard to compare different programs. We add to this by showing that investments in mother and child health care centers pass a simple cost-benefit analysis.

Single Photon Source Driver Designed in ASIC

The single photon source is an important part of the quantum key distribution (QKD) system. At present, the single photon source is large in size and complex in structure for a lot of discrete components which are used. The miniaturization of the photon source is the tendency of the QKD system. We integrate all laser driver electronic module into one single ASIC chip, which can be used to drive the 1550nm DFB laser in random pulse mode and it can greatly reduce the volume of the single photon source. We present the design of the chip named LSD2018 and simulation results before the tape-out. The LSD2018 is fabricated with a 130 nm CMOS process and consists of a discriminator, an adjustable pulse generator, a bandgap reference, an SPI bus, and an amplitude-adjustable current pulse driver. The electronic random pulse from the driver can go 20mA to 120mA in amplitude and 400ps to 4ns in pulse width. The parameters can be set by an SPI bus.
Local Binary Signed Pressure Force Function Based Variation Segmentation Model

Global and local image information is crucial for accurate segmentation of images with intensity inhomogeneity, valuable minute details and multiple objects with various intensities. However, local information is not embedded in popular region-based active contour models, such as the Sign Pressure force (Spf) function based active contour model by K. Zhang et al. In this paper, we propose a region-based active contour model which is able to utilize together image information in local regions and global information. The major contribution of this paper is the introduction of a new local signed pressure force function, which enables the extraction of accurate local and global image information. Therefore, our model can be used to segment images with intensity inhomogeneity, minute valuable details and multiple objects with several intensities. Comparison tests show the advantages of our method in terms of robustness. ABSTRACT Journal of Information & Communication Technology Vol. 9, No. 1, (Spring2015) 01-12

Identification of emission lines in the low-ionization strontium filament near Eta Carinae

We have obtained deep spectra from 1640 to 10 100 A with the Space Telescope Imaging Spectrograph (STIS) of the strontium filament, a largely neutral emission nebulosity lying close to the very luminous star Eta Carinae and showing an uncommon spectrum. Over 600 emission lines, both permitted and forbidden, have been identified. The majority originates from neutral or singly-ionized iron group elements (Sc, Ti, V, Cr, Mn, Fe, Co, Ni). Sr is the only neutron capture element detected. The presence of Sr II, numerous strong Ti  and V  lines and the dominance of Fe  over Fe  are notable discoveries. While emission lines of hydrogen, helium, and nitrogen are associable with other spatial structures at other velocities within the Homunculus, no emission lines from these elements correspond to the spatial structure or velocity of the Sr filament. Moreover, no identified Sr filament emission line requires an ionization or excitation energy above approximately 8 eV. Ionized gas extends spatially along the aperture, oriented along the polar axis of the Homunculus, and in velocity around the strontium filament. We suggest that the strontium filament is shielded from ultraviolet radiation at energies above 8 eV, but is intensely irradiated by the central star at wavelengths longward of 1500 A.
Mechanism Generating Spatial Patterns in Reaction-Diffusion Systems

In 1952, A. M. Turing proposed the notion of “diffusion-driven instability” in his attempt of modeling biological pattern formation. Following his ingenious idea, many reaction-diffusion systems have been proposed later on. On the other hand, Turing patterns can be explained by some cellular automata. Cellular automata are theoretical models which consist of a regular grid of cells, and they exhibit the complex behavior from quite simple rules. In this paper, we describe the mathematical properties of reaction-diffusion systems modeling pattern formation, in particular, Turing patterns. Moreover, we explain ideas which connect differential equations with cellular automata.
What Matters for the Productivity of Kidney Exchange

Almost 100,000 patients are currently waiting for a lifesaving kidney transplant. Buying organs is illegal in the United States. Kidney exchange presents a unique opportunity for patients with a living but incompatible donor (Roth, Sönmez, and Ünver 2004). In 2017, kidney exchange (KE) facilitated approximately 15 percent of all living donor transplants in the United States. In addition to increasing the quality and length of life, each transplant saves several hundreds of thousands of dollars on health-care expenditure over remaining on dialysis. The goal of this paper is to describe the technology with which patients and donors are matched in KE, and to understand what drives the productivity of these platforms. Mechanisms
A Snapshot into the Metabolism of Isomalto-oligosaccharides in Probiotic Bacteria

In vitro and in vivo studies have demonstrated the prebiotic potential of isomalto-oligosaccharides (IMO), comprising α -(1,6)-gluco-oligosaccharides and panose, which selectively stimulate the growth of probiotic bifidobacteria and lactobacilli. The protein machinery conferring the utilization of IMO by probiotics, however, remains vaguely described. We have used genomic, transcriptomic, enzymatic, and biophysical analyses to explore IMO utilization routes in probiotic lactobacilli and bifidobacteria as represented by Lactobacillus acidophilus NCFM and Bifidobacterium animalis subsp. lactis Bl-04, respectively. Utilization of IMO and malto-oligosaccharide ( α -(1,4)-glucosides) appears to be linked both at the genetic and transcriptomic level in the acidophilus group lactobacilli as suggested by reverse transcriptase PCR (RT-PCR) and gene landscape analysis. Canonical intracellular GH13_31 glucan 1,6- α -glucosidases active on IMO longer than isomaltose occur widely in acidophilus group lactobacilli. Interestingly, however, isomaltose, isomaltulose and panose seem to be internalized through a phosphoenoyl pyruvate transferase system (PTS) and subsequently hydrolyzed by a GH4 6-phosphate- α -glucosidases based on whole genome microarray analysis. This sub-specificity within GH4 seems to be unique for lactobacilli mainly from the gut niche, as the sequences from this group segregate from characterized GH4 maltose-6-phosphate- α -glucosidases in other organisms. By comparison, IMO is linked α -galactosidases, GH13_31 oligo 1,6- α -glucosidases and a dual specificity ATP-binding cassette (ABC) transport system active in the uptake of both classes of α -(1,6) glycosides. These data bring novel insight to advance our understanding of the basis of selectivity of IMO metabolism by important gut microbiome members.
Phenomenology of convection-parameterization closure

Abstract. Closure is a problem of defining the convective intensity in a given parameterization. In spite of many years of efforts and progress, it is still considered an overall unresolved problem. The present article reviews this problem from phenomenological perspectives. The physical variables that may contribute in defining the convective intensity are listed, and their statistical significances identified by observational data analyses are reviewed. A possibility is discussed for identifying a correct closure hypothesis by performing a linear stability analysis of tropical convectively coupled waves with various different closure hypotheses. Various individual theoretical issues are considered from various different perspectives. The review also emphasizes that the dominant physical factors controlling convection differ between the tropics and extra-tropics, as well as between oceanic and land areas. Both observational as well as theoretical analyses, often focused on the tropics, do not necessarily lead to conclusions consistent with our operational experiences focused on midlatitudes. Though we emphasize the importance of the interplays between these observational, theoretical and operational perspectives, we also face challenges for establishing a solid research framework that is universally applicable. An energy cycle framework is suggested as such a candidate.
Spatially resolved measurement of plasmon dispersion using Fourier-plane spectral imaging

We show that Fourier-plane imaging in conjunction with the Kretschmann-Raether configuration can be used for measuring polariton dispersion with spatial discrimination of the sample, over the whole visible spectral range. We demonstrate the functionality of our design on several architectures, including plasmonic waveguides, and show that our new design enables the measurement of plasmonic dispersion curves of spatially-inhomogeneous structures with features as small as 3{\mu}m, in a single shot.
The economic impact of HIV/AIDS on rural households in Limpopo Province

Although HIV/AIDS infection is a global problem the epicentre of the disease lies in Africa. In fact about 70 per cent of the global HIV/AIDS infected population can be found in sub-Saharan Africa (UNAIDS 2000). The reported HIV/AIDS sero-prevalence rate for South Africa was estimated at 23.5 per cent in 2000 (Department of Health 2000). This high rate of HIV/AIDS infection poses enormous problems and challenges to the economic development of the country more so because HIV/AIDS affects the most economically productive sector of the population. The high rate of HIV/AIDS infection also calls for an urgent need to assess the socio-economic impact of the pandemic in the country. This paper focuses on the impact of HIV/AIDS on rural households in Limpopo province. The high level of poverty in this province (i.e. 59 per cent) makes this assessment even more pertinent given the fact that poverty stands to increase people’s vulnerability to HIV/AIDS while HIV/AIDS-related morbidity and mortality may cause affected households to be forced into poverty. The specific objectives of this paper are as follows: (i) To assess the economic impact of HIV/AIDS on rural households in Limpopo Province (e.g. the impact of HIV/AIDS on households size household income household expenditures household savings household assets and household borrowings). (ii) To identify rural households’ coping strategies for mitigating the adverse economic impact of HIV/AIDS. (iii) To put forward appropriate policy recommendations to mitigate the economic impact of HIV/AIDS on rural households in Limpopo Province. (excerpt)
The inner 300 parsecs of the Milky Way seen by H.E.S.S.: a Pevatron in the Galactic Centre

The Galactic Centre region has been observed by the High Energy Stereoscopic System (H.E.S.S.) array of ground-based Cherenkov telescopes since 2004 leading to the detection of the very-high-energy γ-ray source HESS J1745-290 spatially coincident with the supermassive black hole Sagittarius A*. Diffuse TeV gamma-ray emission has been detected along the Galactic plane, most likely due to hadronic cosmic-ray interactions with the dense gas of the Central Molecular Zone. The rich 2004-2013 dataset permits detailed spectral and morphological studies of the diffuse emission in the inner 300 pc of the Galactic Centre region. The new results provide an important statement regarding the location and origin of the accelerator of PeV protons. The H.E. S.S. observations of the Pevatron are discussed in the context of the origin of Galactic cosmic rays.
