Ad-hoc networks beyond unit disk graphs (2003)

In this paper we study a model for ad-hoc networks close enough to reality as to represent existing networks, being at the same time concise enough to promote strong theoretical results. The Quasi Unit Disk Graph model contains all edges shorter than a parameter d between 0 and 1 and no edges longer than 1.We show that .in comparison to the cost known on Unit Disk Graphs .the complexity results in this model contain the additional factor 1 /d2. We prove that in Quasi Unit Disk Graphs flooding is an asymptotically message-optimal routing technique, provide a geometric routing algorithm being more efficient above all in dense networks, and show that classic geometric routing is possible with the same performance guarantees as for Unit Disk Graphs if d = 1/v2.

Sumatriptan succinate can be successfully taste-masked by both the solid dispersion method using mannitol by the melting method and Ion exchange resin with Kyron T114. It was also concluded that prepared formulation improve bioavailability by prevention of first pass metabolism.
INHIBITION OF CORROSION OF ALUMINUM AND OTHER METALS IN SODA ASH SOLUTIONS (1943)

Some previously reported curves showing the rate of attack on commercial [Formula: see text] aluminum by [Formula: see text] (by weight) aqueous solutions of various salt–soda-ash mixtures were confirmed. The inhibitive action of various commercial silicates, sodium fluosilicate, and certain other salts in dilute soda ash solutions was determined with aluminum, duralumin, copper, tin plate, and galvanized iron. Of all the salts tested, sodium fluosilicate was found to be the most efficient inhibitor of attack on aluminum. At inhibition in 0.5% aqueous solutions of the sodium-silicate–soda-ash mixtures at 60 °C. the ratio SiO 2 :Na 2 CO 3 and the ratio of silica to surface area of aluminum metal were both roughly constant with all the sodium silicates studied. With sodium fluosilicate, these same ratios are maintained when calculated on the basis of SiF 4 . Increasing the temperature of solution above about 80 °C. appears to increase these inhibition ratios, but the ratios hold at higher concentrations of the aqueous solution of the soda-ash–salt mixture than the 0.5% studied in detail.
Research and design of autonomic computing system model in cloud computing environment (2011)

The aim of autonomic computing is to realize self - management of complex IT systems, which makes systems own the ability of self-configuration, self-recovering, self-optimizing and self-protecting. The aim of cloud computing is to realize the use of resources on demand in distributed environment. But the problem of how to build an autonomic computing model for cloud computing environment has not been solved. This paper proposed a method to design autonomic computing model for cloud computing, which united the application of two computing patterns, so as to solve the problems of high availability and resource management in cloud computing environment.

Development of High-Resolution Pet Mammogram Modules (1997)

Abstract : Because of the limitations of standard X-ray mammography for the early detection of breast cancer, in particular for women with radiographically dense breasts, nuclear medicine imaging techniques are of interest tbr this application. Of these techniques, Positron-Emission Tomography has the greatest potential for high sensitivity to small tumors, and good uptake ratios have been demonstrated for breast tumors with the standard PET radiotracer FDG. The key PET detector attributes for this application are high acceptance and good efficiency at high rates, fine spatial resolution, and good scatter rejection. We are constructing and testing novel prototype PET detector module which have demonstrated high spatial resolution (2.5 mm FWHM in all three dimensions when reconstructing a point source), with large acceptance and a unique active edge and active corner geometry which will be compatible with standard breast imaging procedures including the imaging of axillary nodes. We plan to continue to optimize and test larger-scale, higher efficiency, higher speed and higher resolution modules within the coming year.
The authority of<i>Bildung</i>: educational practices in early childhood education (2015)

This paper is concerned with the transformation of the field of early education in Germany. It poses the question whether these changes can be generally related to the German concept of Bildung – as denoting the children's autonomous activity of engaging themselves and the world. Investigating film material on practices of documentation in early education the paper seeks to clarify the impacts that Bildung has for the constitution of children's subjectivity. Does Bildung bring about a regime of individualization that obfuscates modes of sociality and being with? Are there alternative ways to interpret the modes of subjection in observation?
Constitutive production of leukemia differentiation, colony- stimulating, erythroid burst-promoting, and pluripoietic factors by a human hepatoma cell line: characterization of the leukemia differentiation factor (1985)

Conditioned medium (CM) obtained from a human hepatoma cell line, SK- HEP-1, contains colony-stimulating factors (CSFs) active on murine and human bone marrow-derived granulocyte and macrophage colony-forming units (CFU-GM) and a factor capable of inducing granulocyte-macrophage differentiation (GM-DF) of murine myelomonocytic leukemic cells WEHI- 3B(D+) and human promyelocytic leukemic cells HL-60 when assayed in semisolid agar cultures. The human active granulocyte-macrophage colony- stimulating factor (GM-CSF) for day 7 CFU-GM and the GM-DF for WEHI- 3B(D+) and for HL-60 are not separable by acrylamide agarose column chromatography, eluting at an apparent molecular weight between 20,000 and 35,000 daltons, or by isoelectric focusing (isoelectric point, pH 5.4). In addition, SK-HEP-1 CM contains erythroid burst-promoting activity (BPA) and a factor that promotes the growth of human mixed colonies. SK-HEP-1 cells, which grow as an adherent monolayer, appear not to be endothelial or monocytic in origin since by immunofluorescent staining they are negative for Ia (HLA-DR), monocyte antigen 1 and 2, lysozyme, and factor VIII-related antigen. Positive immunofluorescent staining for keratin and fibronectin suggests the possibility that SK- HEP-1 is an epithelial cell line. Constitutive production of GM-DF as well as other hematopoietic activities including GM-CSF, erythroid BPA, and an activity that promotes the growth of human mixed colony progenitors by a human epithelial tumor cell line, SK-HEP-1, suggests that this cell line is a valuable resource for both large-scale production of these factors and the cloning of the gene(s) that code for these regulators.

The Continuing Evolution of Forensic DNA Profiling - From STRS to SNPS (2006)

Abstract Forensic DNA profiling combines the dynamic science of molecular genetics with the complexities of the forensic context. As such, throughout its twenty-year history, this field has seen continuous change, remarkable growth and an associated level of public, legal and scientific scrutiny previously unknown in the forensic sciences. Almost ubiquitously, applications of forensic DNA profiling have focused on resolving the identity of the donor of a particular sample of biological evidence. This is typically achieved by targeting non-coding microsatellite (or STR) loci. Recently however, novel techniques have emerged that target different DNA polymorphisms and allow scientists to address additional questions about the evidence, beyond the identification of source. In this short review we introduce an example of this next generation of forensic DNA techniques, single nucleotide polymorphisms (or SNPs). We summarise their molecular and technological basis and the manner in which they may be applied to further advance the capabilities of forensic investigators.
An O(<i>n</i> log <i>n</i>) heuristic for steiner minimal tree problems on the euclidean metric (1981)

Abstract An O ( n log n ) heuristic for the Euclidean Steiner Minimal Tree (ESMT) problem is presented. The algorithm is based on a decomposition approach which first partitions the vertex set into triangles via the Delaunay triangulation, then “recomposes” the suboptimal Steiner Minimal Tree (SMT) according to the Voronoi diagram and Minimum Spanning Tree (MST) of the point set. The ESMT algorithm was implemented in FORTRAN‐IV and tested on a number of randomly generated point sets in the plane drawn from a uniform distribution. Comparison of the O ( n log n ) algorithm with an O ( n 4 ) algorithm clearly indicates that the O ( n log n ) algorithm is as good as the previous O ( n 4 ) algorithm in achieving reductions in the ratio SMT/MST of the given vertex set. This is somewhat surprising since the O ( n 4 ) algorithm considers more potential Steiner points and alternative tree configurations.
High-performance iterative BCH decoder architecture for 100 Gb/s optical communications (2013)

This paper presents a iterative Bose-Chaudhuri-Hocquenghem (i-BCH) code and its high-speed decoder architecture for 100 Gb/s optical communications. The proposed architecture features a very high data processing rate as well as excellent error correction capability. The proposed 6-iteration i-BCH code structure with interleaving method allows the decoder to achieve 9.34 dB net coding gain performance at 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-15</sup> decoder output bit error rate to compensate for serious transmission quality degradation. The proposed high-speed i-BCH decoder architecture is synthesized using a 90-nm CMOS technology. It can operate at a clock frequency of 430 MHz and achieve a data processing rate of 100Gb/s. Thus, it has potential applications in next generation forward error correction (FEC) schemes for 100 Gb/s optical communications.
Impact Damage on Titanium Leadng Edges from Small Soft Body Objects (1979)

Impact damage on titanium leading edge configurations was investigated by performing leading edge soft-body impacts on flat-edge and tapered-edge specimens. The objectives were to determine the laboratory specimen size, boundary condition, and test methods necessary to adequately simulate the leading edge local damage of actual blades from soft-body impacts (such as birds). The effects of leading edge geometry, specimen mounting, impact velocity, impactor type, impactor size, and impact angle were investigated. The damage modes excited in ti-tanium were identified. Damage measurement techniques were devised and the damage quantified. Comparisons of the damage were drawn regarding the effects of specimen size and mounting.
Free-standing gratings and lenses for atom optics (1991)

A fabrication process has been developed for making free-standing gratings of silicon nitride. These structures are critical components of an atom interferometer, which uses four gratings as coherent beam splitters of atom waves. The quality of gratings necessary for an interferometer is considerably higher than is needed to demonstrate the diffraction of atoms. In particular, the gratings must be phase coherent over their entire area. This implies that the grating lines must be straight to the order of their linewidth over the full extent of the grating. In addition, the open fraction of the grating structure is more critical for an interferometer. In this paper the development of new fabrication techniques that were used to make free-standing gratings with periods as small as 100 nm and support structure open fractions as high as 0.8 were reported on. To achieve depth-to-linewidth ratios greater than 4:1 with grating periods as small as 100 nm a selective, highly directional reactive ion etching (RIE) process has been developed.
A Bioassay for Plant-Derived Pest Control Agents Using the European Corn Borer12 (1979)

A bioassay procedure for detecting and evaluating pest control agents in plant extracts has been developed using Ostrinia nubilalis (Hübner). Ground seeds are extracted with petroleum ether and ethanol successively; the extracts are mixed with an artificial diet and tested with 7-day-old larvae. Mortality is generally determined after 3, 9, and 29 days. Data are evaluated by means of computer-facilitated statistical analysis. Those extracts exhibiting significantly higher mortality than controls are ranked on the basis of a rating scale. Of 72 plant species representing 36 families, 12 ethanol extracts and 9 petroleum ether extracts have shown strong toxicity and are being fractionated and tested further. The 3 most toxic ethanol extracts were obtained from Berrya ammonilla Roxb., Thevetia thevetioides (HBK.) K. Schum., and Bassia hyssopifolia (Pall.) Kuntze. The 2 most toxic petroleum ether extracts were obtained from Bauhinia vahlii Wight and Am. and Apium sellowianum H. Wolff. All 5 of these extracts gave 100% larval mortality for the corn borer.
Image Stitching Using Structure Deformation (2008)

The aim of this paper is to achieve seamless image stitching without producing visual artifact caused by severe intensity discrepancy and structure misalignment, given that the input images are roughly aligned or globally registered. Our new approach is based on structure deformation and propagation for achieving overall consistency in image structure and intensity. The new stitching algorithm, which has found applications in image compositing, image blending, and intensity correction,consists of the following main processes. Depending on the compatibility and distinctiveness of the 2-D features detected in the image plane, single or double optimal partitions are computed subject to the constraints of intensity coherence and structure continuity. Afterwards, specific 1-D features are detected along the computed optimal partitions, from which a set of sparse deformation vectors is derived to encode 1-D feature matching between the partitions. These sparse deformation cues are robustly propagated into the input images by solving the associated minimization problem in gradient domain, thus providing a uniform framework for the simultaneous alignment of image structure and intensity. We present results in general image compositing and blending, in order to show the effectiveness of our method in producing seamless stitching results from complex input images.
EFFECT OF INOCULANT CARRIER ON SURVIVAL OF Rhizobium ON INOCULATED SEED (1982)

Rhizobia inoculated on leguminous seeds are often exposed to adverse environmental conditions, which affects survival and subsequent effectiveness. Studies were performed to examine the effects of temperature-moisture stress on rhizobia inoculated on seeds in peat-base and oil-base inoculants. Plate count and most-probable-number analyses were used to determine the survival of rhizobia on seeds planted in dry sand at specific sampling times. Plants were grown from inoculated seeds after exposure to 16 days of temperature-moisture stress to assess nodulation and plant growth. For bean seeds that were inoculated with 107 cells of Rhizobium phaseoli 931A, 3.0 X 106 cells/seed (plate counts) were recovered from seeds inoculated with the oil-base carrier, compared with 8.0 X 102/seed with peat-base inoculant. Oil-base inoculants, in this instance, promoted higher survival of rhizobia on seed than did peat-base inoculants. Plants inoculated with oil-base inoculants had higher nodule numbers and weights than plants inoculated with peat-base inoculants. Shoot dry weights and total nitrogen content were likewise increased with oil-base inoculants. Results suggest that oil-base inoculants may provide more protection than peat-base inoculants when rhizobia are inoculated on seeds and exposed to conditions of drought and high temperature.
A Theory of Metallic Ferro- and Antiferromagnetism on Zener's Model (1956)

The importance to the mechanism of ferromagnetism of exchange interaction between conduction electrons and unfilled inner shell electrons (called s-d interaction) has been pointed out by Zener. Especially for rare earth metals, this interaction seems to be the only mechanism which can cause ferro- and antiferromagnetism. However Zener's works are unsatisfactory because his model is phenomenological and moreover does not involve antiferromagnetism and spin wave mode. Our paper considers this s-d interaction on a more rigorous basis. By a certain approximation, there appear long range exchange type interactions between d-electron spins and, in certain conditions both ferro- and antiferromagnetism appear. The excitations of spin wave modes are the same as those in the ordinary modes of the short range exchange force, viz, the energy of the spin wave excitations is proportional to q2 for ferromagnetism and q for antiferromagnetism in the region of small wave vector q. The T3/2 law for the temperature dependence of the magnetization of ferromagnetism is applicable up to very high temperatures, and this result is in good agreement with the results of experiments on metallic ferromagnetism.
Fast automatic gain control employing two compensation loop for high throughput MIMO-OFDM receivers (2006)

The performance of a receiver front-end limits the quality and range of the given communication link. An appropriate design based on well-defined system parameters and architecture can make a huge difference in the performance, cost and marketability of the entire system. In particular, there is a need for improved digital automatic gain control (AGC) for use in multi input multi output orthogonal frequency division multiplexing (MIMO-OFDM) systems with application to wireless local area networks (WLANs), targeted for the upcoming 802.11n standard based in H. Yu et al. (2004) and H. Yu et al. (2005). In this paper, we propose an efficient algorithm and implementation of the digital AGC for next generation WLANs. The proposed AGC algorithm has two feedback loops for gain control to improve convergence speed, and at the same time maintains the stability of the AGC circuit. Also, a complete set of parameters for practical implementation is obtained by various experiments with fixed point constraints and accuracy requirements.
Babesiosis Diagnosis and Treatment (2003)

Human babesiosis due to Babesia microti is an emerging malaria-like infection that is endemic in parts of the northeastern and northcentral United States. The clinical manifestations of babesiosis range from subclinical illness to fulminant disease resulting in death. Prompt and accurate diagnosis is difficult because the signs and symptoms are non-specific. A CBC is a useful screening test since anemia and thrombocytopenia are commonly observed and parasites may be visualized on blood smear. Conclusive diagnosis of this disease generally depends upon microscopic examination of thin blood smears. Babesia frequently are overlooked, however, because parasitemia tends to be sparse, often infecting fewer than 1% of erythrocytes early in the course of the illness. Identification of amplifiable babesial DNA by polymerase chain reaction (PCR) has comparable sensitivity and specificity to microscopic analysis of thin blood smear for detection of babesia in blood. Serologic testing provides useful supplementary evidence of infection because a robust antibody response characterizes human babesial infection, even at the time that parasitemia first becomes detectable. The currently recommended therapy for babesiosis is a 7-10-day course of clindamycin (600 mg every 6 h) and quinine (650 mg every 8 h). Recently, azithromycin (500-600 mg on day 1, and 250-600 mg on subsequent days) and atovaquone (750 mg every 12 h) was found to be equally effective in treating adults experiencing babesiosis. This combination also was associated with fewer adverse reactions than clindamycin and quinine. Exchange transfusion is a potentially life-saving therapy for patients suffering from severe disease with high parasitemia (>5%), significant hemolysis, or renal or pulmonary compromise. Babesiosis may be prevented by avoiding areas such as tall grass and brush where ticks, deer, and mice are known to thrive.
