NetAssay (2014)

Home and business network operators have limited network statistics available over which management decisions can be made. Similarly, there are few triggered behaviors, such as usage or bandwidths cap for individual users, that are available. By looking at sources of traffic, based on Domain Name System (DNS) cues for content of particular web addresses or source Autonomous System (AS) of the traffic, network operators could create new and interesting rules for their network. NetAssay is a Software-Defined Networking (SDN)-based, network-wide monitoring and reaction framework. By integrating information from Border Gateway Protocol (BGP) and the Domain Name System, NetAssay is able to integrate formerly disparate sources of control information, and use it to provide better monitoring, more useful triggered events, and security benefits for network operators.
A Compact and Broadband 90-Degree Waveguide Twist Transformer for Integrated Waveguide Subsystems (2001)

A novel 90-degree waveguide twist is presented. The design features compactness by utilizing a central triple-mode quarter-wave transformer region between input and output waveguides of different cross sections. Return-loss values in excess of 30 dB are obtained over an operating bandwidth close to 20 percent. Larger bandwidths are obtained by using additional quarter-wave steps preceding and/or succeeding the central transformer region. Several different design examples at 4, 6, 19 and 26 GHz are presented for this unique 90-degree twist transformer approach. Experimental verification is provided in the 6 and 19 GHz range.
Review on Comparative Study between Helical Coil and Straight Tube Heat Exchanger (2013)

The purpose of this study is to determine the relative advantage of using a helically coiled heat exchanger against a straight tube heat exchanger. It is found that the heat transfer in helical circular tubes is higher as compared to Straight tube due to their shape. Helical coils offer advantageous over straight tubes due to their compactness and increased heat transfer coefficient. The increased heat transfer coefficients are a consequence of the curvature of the coil, which induces centrifugal forces to act on the moving fluid, resulting in the development of secondary flow. The curvature of the coil governs the centrifugal force while the pitch (or helix angle) influences the torsion to which the fluid is subjected to. The centrifugal force results in the development of secondary flow. Due to the curvature effect, the fluid streams in the outer side of the pipe moves faster than the fluid streams in the inner side of the pipe. The difference in velocity sets-in secondary flows, whose pattern changes with the Dean number of the flow.
Tissue-simulating Phantoms for Assessing Potential Near-infrared Fluorescence Imaging Applications in Breast Cancer Surgery (2014)

Inaccuracies in intraoperative tumor localization and evaluation of surgical margin status result in suboptimal outcome of breast-conserving surgery (BCS). Optical imaging, in particular near-infrared fluorescence (NIRF) imaging, might reduce the frequency of positive surgical margins following BCS by providing the surgeon with a tool for pre- and intraoperative tumor localization in real-time. In the current study, the potential of NIRF-guided BCS is evaluated using tissue-simulating breast phantoms for reasons of standardization and training purposes. Breast phantoms with optical characteristics comparable to those of normal breast tissue were used to simulate breast conserving surgery. Tumor-simulating inclusions containing the fluorescent dye indocyanine green (ICG) were incorporated in the phantoms at predefined locations and imaged for pre- and intraoperative tumor localization, real-time NIRF-guided tumor resection, NIRF-guided evaluation on the extent of surgery, and postoperative assessment of surgical margins. A customized NIRF camera was used as a clinical prototype for imaging purposes. Breast phantoms containing tumor-simulating inclusions offer a simple, inexpensive, and versatile tool to simulate and evaluate intraoperative tumor imaging. The gelatinous phantoms have elastic properties similar to human tissue and can be cut using conventional surgical instruments. Moreover, the phantoms contain hemoglobin and intralipid for mimicking absorption and scattering of photons, respectively, creating uniform optical properties similar to human breast tissue. The main drawback of NIRF imaging is the limited penetration depth of photons when propagating through tissue, which hinders (noninvasive) imaging of deep-seated tumors with epi-illumination strategies.
An efficient machine-independent procedure for garbage collection in various list structures (1967)

A method for returning registers to the free list is an essential part of any list processing system. In this paper, past solutions of the recovery problem are reviewed and compared. A new algorithm is presented which offers significant advantages of speed and storage utilization. The routine for implementing this algorithm can be written in the list language with which it is to be used, thus insuring a degree of machine independence. Finally, the application of the algorithm to a number of different list structures appearing in the literature is indicated.
A method to calculate Stokes parameters and angle of polarization of skylight from polarized CIMEL sun/sky radiometers (2014)

The polarized CIMEL sun/sky radiometers have been routinely operated within the Sun/sky-radiometer Observation NETwork (SONET) in China and some sites of the AErosol RObotic NETwork (AERONET) around the world. However, the polarization measurements are not yet widely used due to in a certain degree the lack of Stokes parameters derived directly from these polarization measurements. Meanwhile, it have been shown that retrievals of several microphysical properties of aerosol particles can be significantly improved by using degree of linear polarization (DoLP) measurements of polarized CIMEL sun/sky radiometers (CE318-DP). The Stokes parameters Q and U, as well as angle of polarization (AoP) contain additional information about linear polarization and its orientation. A method to calculate Stokes parameters Q, U, and AoP from CE318-DP polarized skylight measurements is introduced in this study. A new polarized almucantar geometry based on CE318-DP is measured to illustrate abundant variation features of these parameters. The polarization parameters calculated in this study are consistent with previous results of DoLP and I, and also comparable to vector radiative transfer simulations.
Effect of Stocking Pressure on Animal and Acre Output<sup>1</sup> (1965)

Synopsis Daily gains of the steers on the lighter stocked pastures were greater than those on the heavier stocked pastures. However, a large difference in stocking pressure had to be imposed before the difference in either steer gains, carrying capacity, or herbage dry matter digestibility were significant.
High Fidelity Antenna Model Validation Results of a GNSS Multipath Limiting Antenna (2011)

The local area augmentation system (LAAS) is a proposed satellite-based landing system by the Federal Aviation Administration (FAA) to serve as a navigation aid for commercial aircraft during the approach and landing phase of flight. The LAAS utilizes a special ground-based antenna array called the multipath limiting antenna (MLA) to provide differentially corrected global navigation satellite system (GNSS) data to oncoming aircraft as well as to reduce the largest error contributor to pseudo-range estimates; the ground multipath. The performance of the MLA is characterized in terms of its desired-to-undesired (D/U) gain ratio, phase center variation (PCV) and group delay (GD). A high fidelity antenna model (HFAM) of the MLA is presented that estimates the D/U, PCV, and GD as a function of elevation angle. The model consists of two main components: (1) a microwave feed distribution circuit model created using a circuit simulator, and (2) a radiating structure model developed using a full-wave method of moments (MoM) field solver. The performance of the model was assessed against antenna range measurements. The results of the HFAM show good correlation for the D/U and PCV while a significant bias was observed on the results for the GD. The dependence of the GD on the radiating element's impedance, tuning process, and Doppler frequency shift are demonstrated via simulations.

Room Temperature Magnetoelectric Effects on Single Slabs of Z-type Hexaferrites (2011)

In this paper, magnetoelectric effects of Sr Z-type hexaferrite, Sr3Fe24Co2O41, at room temperature is measured. The change in remanence magnetization was measured by applying a DC voltage or electric field across a slab of hexaferrite. Changes of ~ 18% in remanence was observed in an electric field of 10,000V/cm implying a similar change in the microwave permeability at frequencies below 3GHz. In these types of measurements high resistivity is critical in order to reduce current flow in the hexaferrite. The resistivity of the hexaferrite was raised to 4.28x10^8 ohm?-cm by annealing under oxygen pressure. The measurements indicate that indeed electric polarization and magnetization changes were induced by the application of magnetic and electric fields, respectively. The implications for microwave applications appear to be very promising at room temperature.
Low-pressure ion nitriding of AISI 304 austenitic stainless steel with an intensified glow discharge (1993)

Low-pressure ion nitriding of AISI 304 austenitic stainless steel was conducted in the present study by intensifying the glow discharge. Plasma intensification was produced by thermionic emission and by utilizing a triode glow discharge system. The results showed that under the intensified plasma conditions, effective nitriding can be accomplished at relatively low temperatures. The nitride layer had a dense structure, high purity and an ultrafine microstructure with a grain (nucleus) size less than 80 Å. The nitriding treatment produced a thin layer of high nitrides (FeN and Fe2N) followed by a diffusion controlled layer of (Fe,Cr)3N. X-ray and electron-diffraction analysis showed that all nitrides were hexagonal in crystal structure. The intensified plasma treatment caused a significant increase in the nitride layer growth kinetics. The enhancement of the nitrogen diffusion was attributed to the higher surface concentration of vacancies due to the energetic particle bombardment and to grain boundary diffusion in the nitride phase. A simplified diffusion model is developed to estimate the effective nitrogen diffusivity under the intensified plasma ion nitriding.
Sensitivity of Hepatitis C Virus RNA to the Antiviral Enzyme Ribonuclease L Is Determined by a Subset of Efficient Cleavage Sites (2004)

Ribonuclease L (RNase L) cleaves RNA predominantly at single-stranded UA and UU dinucleotides. Intriguingly, hepatitis C virus (HCV) RNAs have a paucity of UA and UU dinucleotides, and relatively interferon (IFN)-resistant strains have fewer UA and UU dinucleotides than do more IFN-sensitive strains. In this study, we found that contextual features of UA and UU dinucleotides dramatically affected the efficiency of RNase L cleavage in HCV RNA. HCV genotype la RNA was cleaved by RNase L into fragments 200-1000 bases in length, consistent with 10-50 RNase L cleavage sites within the 9650-base long viral RNA. Using primer extension, we found that HCV RNA structures with multiple single-stranded UA and UU dinucleotides were cleaved most efficiently by RNase L. UA and UU dinucleotides with 3' proximal C or G residues were cleaved infrequently, whereas UA and UU dinucleotides within dsRNA structures were not cleaved. 5'-GUAC-3' and 5'-CUUC-3' were particularly unfavorable contexts for cleavage by RNase L. More than 60% of the UA and UU dinucleotides in HCV la RNA were not cleaved by RNase L because of these contextual features. The 10-30 most efficiently cleaved sites were responsible for approximately 50%-85% of all RNase L cleavage events. Our data indicate that a relatively small number of the UA and UU dinucleotides in HCV RNA mediate the overall sensitivity of HCV RNA to cleavage by RNase L.
Identification of the Cloned Gene for the Murine Transplantation Antigen H-2K<sup>b</sup>by Hybridization with Synthetic Oligonucleotides (1983)

The H-2K(b) gene is a member of the large major histocompatibility complex class I gene family. Since many members of this family cross-hybridize with class I cDNA probes, the cloned H-2K(b) gene was identified by hybridization with specific oligonucleotide probes. This clone was definitively shown to encode the H-2K(b) polypeptide by partial DNA sequencing and by serological and tryptic peptide analyses of the expressed product.
PURY: a database of geometric restraints of hetero compounds for refinement in complexes with macromolecular structures (2008)

The number and variety of macromolecular structures in complex with ;hetero' ligands is growing. The need for rapid delivery of correct geometric parameters for their refinement, which is often crucial for understanding the biological relevance of the structure, is growing correspondingly. The current standard for describing protein structures is the Engh-Huber parameter set. It is an expert data set resulting from selection and analysis of the crystal structures gathered in the Cambridge Structural Database (CSD). Clearly, such a manual approach cannot be applied to the vast and ever-growing number of chemical compounds. Therefore, a database, named PURY, of geometric parameters of chemical compounds has been developed, together with a server that accesses it. PURY is a compilation of the whole CSD. It contains lists of atom classes and bonds connecting them, as well as angle, chirality, planarity and conformation parameters. The current compilation is based on CSD 5.28 and contains 1978 atom classes and 32,702 bonding, 237,068 angle, 201,860 dihedral and 64,193 improper geometric restraints. Analysis has confirmed that the restraints from the PURY database are suitable for use in macromolecular crystal structure refinement and should be of value to the crystallographic community. The database can be accessed through the web server http://pury.ijs.si/, which creates topology and parameter files from deposited coordinates in suitable forms for the refinement programs MAIN, CNS and REFMAC. In the near future, the server will move to the CSD website http://pury.ccdc.cam.ac.uk/.

Phase transitions in CH<sub>3</sub>NH<sub>3</sub>ClO<sub>4</sub>and CH<sub>3</sub>ND<sub>3</sub>ClO<sub>4</sub> (1992)

Abstract Infrared and Raman spectra (10–5000 cm−1) of CH3NH3ClO4 and CH3ND3ClO4 were investigated in the temperature range 90–470 K. Single crystal Raman spectral studies were also carried out at 310 and 90 K. Assignments of the measured frequencies to the internal modes have been made. Based on a systematic temperature dependent study of widths and frequencies of prominent bands, the phase transitions at 321 and 451 K are characterized. In phase III (below 321 K), the cations and anions show splittings due to inequivalent sites. In phase II (between 321 and 451 K), the results show the absence of inequivalent sites and large motional freedom of the anion. In phase I (above 451 K), the cations and anions undergo isotropic reorientational motions. Key Words: Phase transitionsRaman spectraInfrared spectraMonomethylammonium perchlorate
Differential Responsiveness of the Somatotroph to Growth Hormone-Releasing Factor during Early Neonatal Development in the Rat* (1986)

The effects of human pancreatic GH-releasing factor-40 (hpGRF-40; 0.01-100 nM) and (Bu)2cAMP (0.015-1.5 mM) on GH release from primary monolayer cultures of pituitary cells were evaluated in rats of three age groups: postnatal days 2 and 12, and young adult males (3-4 months). Both hpGRF-40 and (Bu)2cAMP elicited a dose-related increase in GH release in cell cultures from each age group. However, the magnitude of the fractional increase over basal release was markedly age dependent. hpGRF-40-stimulated GH release (expressed as a percentage of control values) was greater in cultured cells of 2-day-old than of 12-day-old rats, which was, in turn, significantly greater than in cells of adult rats (P less than 0.001). Maximum hpGRF-40-stimulated GH release was 1058 +/- 50% of control values (+/- SE) in 2-day-old, 617 +/- 21% of control values in 12-day-old, and 405 +/- 6% of control values in adult pituitary cell cultures. The slopes of the dose-response curves differed significantly among the three age groups (P less than 0.001) and varied inversely with increasing age. GH release induced by (Bu)2cAMP was similarly age dependent; maximal stimulated release was 1073 +/- 20%, 414 +/- 4%, and 259 +/- 7% of control values in cultured cells of 2-day-old, 12-day-old, and adult rats, respectively (P less than 0.001 for age effect at each dose). As with hpGRF-40, the slopes of the dose-response curves for (Bu)2cAMP decreased with advancing age (P less than 0.001). Intracellular GH storage during culture, basal release of GH, and serum GH were also age dependent. Pooled serum GH was consistently elevated in 2-day-old rats (139 +/- 2 ng ml-1), became lower and more variable in 12-day-old rats (62 +/- 14 ng ml-1), and was even more variable in adult male rats (79 +/- 23 ng ml-1), owing to random sampling during spontaneous secretory pulses. These results indicate that the stimulatory effects of GRF and (Bu)2cAMP on GH secretion from cultured rat pituitaries vary with age; pituitary cells of newborn rats are relatively more sensitive to these secretagogues than those of adult rats. This increased responsiveness of the neonatal somatotroph to GRF may contribute to the elevation of the plasma GH concentration which is characteristic of the perinatal period in the rat.
Friction and wear behavior of the polyurethane composites modified by bishydroxyl-terminated polydimethylsiloxane (2013)

Purpose – A series of polyurethane/bishydroxyl-terminated polydimethylsiloxane composites (PU/BTPDMS) were prepared. The effect of BTPDMS content on the tribological properties of the PU/BTPDMS composites was studied. The paper aims to discuss these issues. Design/methodology/approach – The composites were prepared by a pre-polymer method. The properties were measured with Fourier transform infrared spectroscopy (FTIR), thermogravimetry analysis (TGA). The friction and wear characteristic of the composites were examined with MRH-3 friction-abrasion testing machine. The worn surfaces of the composites were investigated by scanning electron microscopy (SEM). Findings – Experimental results indicated that the polyurethane modified with 7 percent BTPDMS had better tribological property than pure PU and other PU/BTPDMS composites in the present study. It exhibits lower coefficient of friction (COF) and lower wear rate value, especially under water lubrication. Originality/value – The polyurethane was synthesized by a pre-polymer method combination with chemical modification.
High Voltage Direct Current Transmission (1998)

Since the first edition of this book in 1983, HVDC technology has continued to expand and few power systems can now escape its influence. This thoroughly revised text develops the coverage in the first edition, describing the variety of reasons justifying the use of DC transmission as well as the basic concepts and techniques involved in the AC-DC and DC-AC conversion processes. It has been fully updated and enlarged to include descriptions of the widening applications of DC, the current state-of-the-art thyristors and other semiconductor devices, and the new developments that continue to make HVDC a competitive technology. The book should be of interest to practising engineers and researchers involved in the power industry. It will also be of assistance to lecturers and students in the power systems and power electronics disciplines

A Custom Chip Set for a Frequency-Agile High-Resolution Sonar Array (2007)

This paper describes two custom-integrated circuits, which form the core building blocks of a versatile wideband sonar array. An analog 0.5-mum complementary metal-oxide-semiconductor (CMOS) chip houses a preamplifier, an antialias filter, and a high-resolution (14-16 b) data converter based on delta-sigma modulation techniques. A complementary 0.35-mum digital CMOS chip incorporates a four-stage multirate filter cascade, which provides a wideband and two narrowband outputs. The complex narrowband outputs are obtained via a subsampling mixer and span over the top 15% or the top 10%, respectively, of the original band. The system sampling clock can vary from 2 to 10 MHz to enable tuning to a specific frequency window located anywhere between 30 and 150 kHz. Both chips process four sonar channels in parallel and, when clocked at 10 MHz, dissipate a combined power of 416 mW (104 mW per channel).
Cloning and characterization of a cotton lipid transfer protein gene specifically expressed in fiber cells (1997)

A cotton genomic library was screened using a fiber-specific cDNA (GH3) encoding a lipid transfer protein (LTP). One genomic clone (1.7 kb DNA insert) containing the Ltp gene (Ltp6) was sequenced and characterized. The Ltp6 contains an open reading frame of 360 bp, which is interrupted by a single intron (136 bp) located in the region corresponding to the C-terminal of the protein. The derived amino-acid sequence of LTP6 is 64% homologous to that of GH3. Like the GH3 gene, the Ltp6 is specifically expressed in fiber cells in a temporal manner. However, its expression level is lower than that of GH3.
SON (silicon-on-nothing) technological CMOS platform: highly performant devices and SRAM cells (2005)

In this paper, we demonstrate for the first time full integration of highly performant NMOS and PMOS silicon-on-nothing (SON) devices into circuits. We demonstrated fully functional SRAMs cells with very good yield, showing static noise margin (SNM) of 175mV and write margin (WM, stable "read 0") above 500mV. The optimized SON devices show performance for NMOS and for PMOS that is among the best published data (with drive current up to 1100/350/spl mu/A//spl mu/m for 138/20nA//spl mu/m I/sub off/ for NMOS and PMOS devices respectively @V/sub dd/=1.2V, I/sub ox/=16A). Finally, we present also the implementation of the SON process into a new "localized SOI" architecture on bulk. This new and simplified SON process is also demonstrated by fully operational SRAM cells.
