Hybrid superprism with low insertion losses and suppressed cross-talk (2005)

We demonstrate with the two-dimensional finite-difference time-domain method that an adiabatic transition in a superprism with an interface along the [1 2 ] direction enhances the transmission through the superprism to more than 90% (-0.5 dB) over the wavelength range 1.47-1.68 mum , including the telecommunication C and L bands. We also show that diffraction governed by a quasinegative index of refraction inside the superprism can be used to obtain nearly transform-limited beam widths at the output of the superprism. The reduction of the beam width at the output suppresses cross-talk and greatly enhances the achievable frequency resolution of the superprism.
Calculation of Flow Instability Inception in High Speed Axial Compressors Based on an Eigenvalue Theory (2014)

This paper applies a theoretical model developed recently to calculate the flow instability inception point in axial high speed compressors system with tip clearance. After the mean flow field is computed by 3D steady computational fluid dynamics (CFD) simulation, a body force approach, which is a function of flow field data and comprises of one inviscid part and the other viscid part, is taken to duplicate the physical sources of flow turning and loss. Further by applying appropriate boundary conditions and spectral collocation method, a group of homogeneous equations will yield from which the stability equation can be derived. The singular value decomposition (SVD) method is adopted over a series of fine grid points in frequency domain, and the onset point of flow instability can be judged by the imaginary part of the resultant eigenvalue. The first assessment is to check the applicability of the present model on calculating the stall margin of one single stage transonic compressors at 85% rotational speed. The reasonable prediction accuracy validates that this model can provide an unambiguous judgment on stall inception without numerous requirements of empirical relations of loss and deviation angle. It could possibly be employed to check overcomputed stall margin during the design phase of new high speed compressors. The following validation case is conducted to study the nontrivial role of tip clearance in rotating stall, and a parameter study is performed to investigate the effects of end wall body force coefficient on stall onset point calculation. It is verified that the present model could qualitatively predict the reduced stall margin by assuming a simplified body force model which represents the response of a large tip clearance on the unsteady flow field.
Total implantation of the implex TICA hearing amplifier implant for high-frequency sensorineural hearing loss (2001)

Hearing devices may be classified as sound-producing hearing aids, electrically stimulating devices, and vibratory hearing aids. Because patients may lose physiologic cochlear amplification, hearing devices for the treatment of sensorineural hearing loss are used as signal amplifiers. The totally implantable communication assistance (TICA) device is a European-approved totally implantable vibratory amplifier implant. It picks up the sound signal transcutaneously from the external auditory canal near the eardrum, amplifies the signal, and transduces the signal into microvibrations that are delivered to the ossicular chain.

Improving the Performance of Green LEDs by Low-Temperature Annealing of p-GaN with PdZn (2009)

This article reports the electrical properties of p-GaN annealed at low activation temperature by using a PdZn film in green multiquantum well (MQW) light-emitting diodes (LEDs). Electroluminescence (EL) intensity of green MQW LED annealed at using PdZn was improved by 33% at compared to that annealed at without PdZn. These results are attributed to an increase of the hole concentration of p-GaN due to removal of hydrogen in p-GaN by PdZn and a decrease in thermal damage of MQW at low activation temperature.
Effect of deposition variables on the chemical vapor deposition of TiC using propane (1986)

TiC was deposited onto cemented tungsten carbide by a chemical vapor deposition from a TiCl4–H2–C3H8 gas mixture in a horizontal resistance furnace. The deposition rate and the surface morphology of the coatings were investigated with mC/Ti, deposition temperature and total deposition pressure. Deposition rate is maximum at the mC/Ti value of about 0.9 and deposition of TiC is possible in the temperature range 850–950 °C at atmospheric pressure. By reducing the total pressure, the possible temperature range for the reaction is enlarged. The theoretical deposition efficiency and the supersaturation of reactants can also be enhanced by reducing the total pressure, which results in fine and uniform crystal size distributions. The preferred orientation of the TiC deposits is (200).
Electrical conductivity and carrier concentration control in β-Ga2O3 by Si doping (2008)

Electrical conductivity of β-Ga2O3 has been attributed so far to an oxygen deficiency, the donors presumably being oxygen vacancies. This letter shows, however, that the conductivity can be intentionally controlled over three orders of magnitude by Si doping. The related free-carrier concentration, which varies between 1016–1018cm−3, corresponds to a 25%–50% effective Si donors. Since Si is the main impurity present in Ga2O3 powders—in the order of the studied doping levels—we conclude that the electrical conductance of β-Ga2O3 can be attributed to Si impurities, and that the contribution of oxygen vacancies, if any, is not dominant.

A glycoprotein associated with the non-A, non-B hepatitis agent(s): isolation and immunoreactivity. (1985)

A glycoprotein was isolated and purified to homogeneity from the serum of a patient with chronic non-A, non-B hepatitis. NaDodSO4/PAGE of the glycoprotein revealed a single major band at Mr approximately 77,000. Antibodies to this glycoprotein were shown to possess the following immunoreactivity: (i) they reacted by radioimmunoassay with sera obtained at the time of diagnosis from 17 of 42 patients with non-A, non-B hepatitis and with only 2 of 58 sera from either matched controls or patients with hepatitis A or hepatitis B, (ii) they reacted with sucrose gradient fractions from a proven infectious non-A, non-B hepatitis serum at a peak density of 1.14 g/ml and in the soluble protein fractions on top of the gradient, and (iii) they reacted in ELISA with disrupted human T-cell lymphocytotropic virus type III (HTLV-III), and (iv) they reacted in immunoblots with a protein of Mr 74,000 derived from HTLV-III.
Genetic strategy for identification or genes involved in citrus salt stress tolerance : Status of genome mapping program (2008)

Salt stress is one of the most obvious effects of high salinity on Citrus, which is classified among the most sensitive tree crops. Genetic and genomic analysis of tolerant and sensitive plants is a prerequisite for breeding programs and the selection of more adapted varieties to high salinity. The combined approach of genetic mapping and localization of candidate genes has been applied in plant genetics in the past decade with the objective of characterizing and cloning quantitative trait loci (QTLs). The segregation of the tolerancel sensitivity to salt character was initiated on the F2 population resulting from the crossing Cleopatra mandarin X Poncirus trifoliata. Citrus linkage map was derived from the segregation analysis of SSR markers from EST or BAC ends. From many polymorphic primers only few makers have Mendelian segregation. The skewed segregation can be due to abnormal meiosis at the intergeneric level. The excess of homozygous locus was observed only for the marker CiBE2626b. No difference was observed between frequency of alleles from Poncirus and alleles from mandarin in homozygous loci. Half ofF2 population (61 hybrids) has a percentage of homozygous loci lower than or equal to 20%. Other hybrids seem to have proportions of homozygous and heterozygous loci that follow a normal distribution although there is a slight shift of sorne homozygote individuals to represent the expected Gaussian curve (- 0.45 instead of 0.5). We have also studied the segregation and mapped several candidate genes putatively involved in salinity tolerance. We plan to confirm the role played by these genes by gene expression analysis from selected homozygous F2 genotypes under strong salt stress conditions. We will measure the effects of salt stress on physiological traits on the segregating population. (Texte intégral)
WWOX Gene and Gene Product: Tumor Suppression Through Specific Protein Interactions (2010)

The WWOX gene, an archetypal fragile gene, encompasses a chromosomal fragile site at 16q23.2, and encodes the approximately 46-kDa Wwox protein, with WW domains that interact with a growing list of interesting proteins. If the function of a protein is defined by the company it keeps, then Wwox is involved in numerous important signal pathways for bone and germ-cell development, cellular and animal growth and death, transcriptional control and suppression of cancer development. Because alterations to genes at fragile sites are exquisitely sensitive to replication stress-induced DNA damage, there has been an ongoing scientific discussion questioning whether such gene expression alterations provide a selective advantage for clonal expansion of neoplastic cells, and a parallel discussion on why important genes would be present at sites that are susceptible to inactivation. We offer some answers through a description of known WWOX functions.
The Effect of Mechanochemical Treatment of the Cellulose on Characteristics of Nanocellulose Films (2016)

The development of the nanomaterials with the advanced functional characteristics is a challenging task because of the growing demand in the market of the optoelectronic devices, biodegradable plastics, and materials for energy saving and energy storage. Nanocellulose is comprised of the nanosized cellulose particles, properties of which depend on characteristics of plant raw materials as well as methods of nanocellulose preparation. In this study, the effect of the mechanochemical treatment of bleached softwood sulfate pulp on the optical and mechanical properties of nanocellulose films was assessed. It was established that the method of the subsequent grinding, acid hydrolysis and ultrasound treatment of cellulose generated films with the significant transparency in the visible spectral range (up to 78 % at 600 nm), high Young's modulus (up to 8.8 GPa), and tensile strength (up to 88 MPa) with increased ordering of the packing of the cellulose macromolecules. Morphological characterization was done using the dynamic light scattering (DLS) analyzer and transmission electron microscopy (TEM). The nanocellulose particles had an average diameter of 15-30 nm and a high aspect ratio in the range 120-150. The crystallinity was increased with successive treatments as shown by the X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analysis. The thermal degradation behavior of cellulose samples was explored by thermal gravimetric analysis (TGA).

Single-chip CMOS pulse generator for UWB systems (2005)

This paper describes the integration in a CMOS 130 nm technology of an ultra wide band (UWB) pulse generator. The implemented generator controls the output pulse shape, and thus the corresponding spectrum. Furthermore, the pulse generator supports both position modulation (2-PPM) and polarity modulation (BPSK) and draws 5 mA from 1.2 V. Spectral and temporal laboratory measurements of the single-chip pulse generator are presented.
Hydrogen-bonded diketopyrrolopyrrole (DPP) pigments as organic semiconductors (2014)

Diketopyrrolopyrroles (DPPs) have recently gained attention as building-blocks for organic semiconducting polymers and small molecules, however the semiconducting properties of their hydrogen-bonded (H-bonded) pigment forms have not been explored. Herein we report on the performance of three archetypical H-bonded DPP pigments, which show ambipolar carrier mobilities in the range 0.01-0.06 cm<sup>2</sup>/V s in organic field-effect transistors. Their semiconducting properties are correlated with crystal structure, where an H-bonded crystal lattice supports close and relatively cofacial π-π stacking. To better understand transport in these systems, density functional theory calculations were carried out, indicating theoretical maximum ambipolar mobility values of ∼0.3 cm<sup>2</sup>/V s. Based on these experimental and theoretical results, H-bonded DPPs represent a viable alternative to more established DPP-containing polymers and small molecules where H-bonding is blocked by N-alkylation.
Size and Flexibility Define the Inhibition of the H3N2 Influenza Endonuclease Enzyme by Calix[n]arenes (2019)

Inhibition of H3N2 influenza PA endonuclease activity by a panel of anionic calix[n]arenes and β-cyclodextrin sulfate has been studied. The joint experimental and theoretical results reveal that the larger, more flexible and highly water-soluble sulfonato-calix[n]arenes have high inhibitory activity, with para-sulfonato-calix[8]arene, SC8, having an IC<sub>50</sub> value of 6.4 μM. Molecular docking calculations show the SC8 can interact at both the polyanion binding site and also the catalytic site of H3N2 influenza PA endonuclease.
Neuronal Survival is Compromised by Ethanol: Extracellular Mediators (2006)

Abstract This chapter discusses the effects of ethanol on the incidence of neuronal death and the extracellular mediators that define this death. Ethanol-induced neuronal death occurs during defined periods of the developmental time line. These time periods coincide with those of neuronogenesis and primary synaptogenesis, which are periods of naturally occurring neuronal death (NOND). Exposure of ethanol at this time may exacerbate processes involved in NOND.
Development Of Model Based Design Curriculum (2020)

Abstract NOTE: The first page of text has been automatically extracted and included below in lieu of an abstract Development of Model-Based Design Curriculum Abstract Model-Based Design is increasingly prevalent in industrial sectors including aerospace and automotive, but lacking from college and university curricula. The need for students to be adept at the modeling of systems, their associated subsystems, and overall system controller was the impetus for The MathWorks to partner with Rose-Hulman Institute of Technology to “bridge the gap” between industry and academia by developing a Model-Based Design course within the context of a series hybrid-electric vehicle. Students apply Model-Based Design, beginning with simple component models for a complex, multi-disciplinary system in need of control. Incremental improvements to the components and controller enable students to assess the impact of their changes and determine if the associated level of complexity is warranted. Moreover, the deployment of “executable specifications” enables students to identify and rectify errors early in the design process, whereby they may save dramatically on time and cost. Assessment data are being collected to qualify the academic impact of Model-Based Design. Introduction Given competitive pressures, and time and cost constraints, developing a product on time and within budget requires a systematic approach to design and realization. The systematic design and realization process in the aerospace and automotive industries is typically represented by a V diagram as shown in Figure 1.

Potential thermal artifacts in hip joint wear simulators (1999)

Frictional heat was monitored during wear tests of ultrahigh molecular weight polyethylene acetabular cups bearing against femoral balls of metal or ceramic in a hip simulator, using bovine serum as a lubricant. About 1 to 2 h of continuous cycling were required for the temperature in the zone of contact between the cup and ball to rise to its maximum steady value, and this equilibrium temperature was markedly higher with increased load and/or cycling rate. Frictional heating caused substantial precipitation of the proteins from the serum and, in some of the tests running at 1.5 or 2 Hz, an adherent proteinaceous layer was observed attached to the surface of the balls. The maximum temperature was also substantially higher in tests run with the cup mounted above the ball rather than below. Surprisingly, the tests running at higher frictional torque and temperature (i.e., those with the most protein precipitation and/or adherent layers) produced the least wear of the polyethylene. This might have been due to the solid proteins that formed a protective layer between the ball and cup. Because patients with hip prostheses typically do not walk for hours without rest, the maximum temperatures in vivo are likely to be much lower than those reached in the hip simulator. Therefore, the affects of protein precipitation on the resultant wear properties of the materials should be considered potential artifacts of the hip simulator tests. Increasing the volume of the lubricant bath reduced the maximum temperatures for tests running at 1.5 Hz but had little affect at 2 Hz. Reducing the cycling rate is an effective way to avoid overheating of the specimens, but this necessarily extends the time required to complete a test.
Support vector machines-based identification of alternative splicing in Arabidopsis thaliana from whole-genome tiling arrays (2011)

The method developed in this work expands the scarce repertoire of analysis tools for the identification of alternative mRNA splicing from whole-genome tiling arrays. Our predictions are highly enriched with known AS events and complement the A. thaliana genome annotation with respect to AS. Since all predicted AS events can be precisely attributed to experimental conditions, our work provides a basis for follow-up studies focused on the elucidation of the regulatory mechanisms underlying tissue-specific and stress-dependent AS in plants.
Use of Pearl Millet, Sorghum, and Triticale Grain in Broiler Diets (1989)

‘Tif 23 BE’ pearl millet [ Pennisetum glaucum (L.) R. Br.], ‘Taylor‐Evans 101’ grain sorghum ( Sorghum bicolor L. Moench), and ‘Morrison’ and ‘Beagle 82’ triticale ( X Triticosecale Wittmack) all show potential as high yielding grain crops and poultry feed ingredients in the Southeastern USA. Trials were conducted substituting each grain for 50 or 100% of the corn ( Zea mays L.) in the control diet. The diets were formulated on an isonitrogenous and isocaloric basis and were fed to chicks ( Gallus domesticus ) from 1 to 21 d of age. Pearl millet and grain sorghum replaced corn in the diet of chicks without adversely affecting gain or feed efficiency of the chicks. Feed efficiency and body weight were generally reduced for birds fed diets with triticale in the first trial. No differences in feed efficiency were observed in the second triticale trial but body weight of the chicks fed the diet with 100% Morrison triticale was significantly reduced.

A simple intrinsic measure for rapid crack propagation in bimodal polyethylene pipe grades validated by elastic–plastic fracture mechanics analysis of data from instrumented Charpy impact test (2016)

Conventional test procedures, such as the S4 test to analyze the resistance against rapid crack propagation (RCP) of plastic pipe materials are characterized by usage of a lot of material, are far from saving of time and they are‐in need of special experimental set‐ups. Therefore, in the last decade, small‐scale accelerated reliable tests (SMART) are developed ‐ worldwide to overcome the disadvantage of such conventional tests. In this article, fracture mechanics based analysis of instrumented Charpy impact test data for a set of bimodal high‐density polyethylene pipe grades are compared with data of the conventional Charpy impact test. From this comparison the Charpy impact strength at −30°C comes forth as a robust reproducible measure of the resistance to RCP and it is therefore proposed as a SMART method to rank materials with respect to RCP resistance.
