A 1.3 GHz NMR Magnet Design Under High Hoop Stress Condition (2010)

NMR magnets using high-T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> superconductors (HTS) to generate high magnetic fields exceeding 25 T are currently being designed by several organizations. In these designs, the HTS is used for the inner coils, and the other coils consist of NbTi and Nb <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> Sn wires. The YBCO wire, which is a typical HTS, has excellent critical current performance over a wide range of magnetic fields and tolerates high tensile stress of up to 700 MPa. These properties make it possible to realize a high-field NMR magnet. In particular, the superior mechanical strength allows for the high-stress criterion of the electromagnetic force to be applied to the design of the magnets. In this study, we show the conceptual design of 1.3 GHz (30.5 T) NMR magnets under the condition of high hoop stress of 500 MPa. To achieve high magnetic field homogeneity in these designs, we propose three magnet design plans that have different arrangements of the compensation coils. We assumed that the magnet would be operated by the driven mode at 4.2 K. We also considered the strong angular dependence of the critical current of the YBCO wires to design the magnet.
Frequency responses of hearing aids and their effects on the speech perception of eight hard-of-hearing subjects (1974)

This dissertation examines the relationship between frequency response and word-discrimination performance of hearing-impaired persons. Three questions are addressed: does the restoration of the normal field-to-eardrum transfer function improve word discrimination; is the restoration of the normal shape of the audibility curve (uniform hearing level at all frequencies) beneficial to hearing-impaired listeners; and can speech discrimination be improved by an extension of the present narrow-band response in hearing aids.

Quantitative Phase-field Simulation of Dendritic Equiaxed Growth and Comparison with in Situ Observation on Al – 4 wt.% Cu Alloy by Means of Synchrotron X-ray Radiography (2014)

Dendritic equiaxed growth from the melt by continuous cooling-down is investigated by quantitative 2D phase-field simulations. The results are compared with detailed data from solidification experiments on Al–4 wt.% Cu alloy with in situ X-ray monitoring. In a first step, the simulation of an isolated equiaxed alloy dendrite growing freely in <100>-direction in the melt is performed. Then, the impingement between two grains is considered by simulating two dendritic crystals growing towards each other in <100>-direction. From the phase-field simulations, the time evolution of the equiaxed crystals is characterized by measuring the lengths and tip velocities of the primary dendrite arms in free growth and in the presence of neighbor interaction, which enables the analysis of growth dynamics. In a second part, the results of the phase-field simulations are compared to data extracted from an experiment on Al – 4 wt.% Cu alloys carried out at the European Synchrotron Radiation Facility (ESRF), with in situ and real-time characterization by means of X-ray radiography, and to analytical relationship for dendrite tip growth. The limitations of 2D-phase-field simulations to fully describe the dynamic formation and interaction of dendritic equiaxed grains are briefly discussed.
A 118 dB PSRR, 0.00067% (-103.5 dB) THD+N and 3.1 W Fully Differential Class-D Audio Amplifier With PWM Common Mode Control (2016)

This paper presents a fully differential Class-D audio amplifier using pulse-width modulation (PWM) commonmode control to enhance the power supply rejection ratio (PSRR) and linearity. The input feed-forward technique with resistive summation is adopted in the loop filter to reduce internal swing and signal-dependent terms for further linearity enhancement. Moreover, a single amplifier biaquad (SAB) technique is utilized to reduce the number of op-amps for low-power consideration. The Class-D audio amplifier achieves a high PSRR of 118 dB for 217 Hz power supply ripples and a low total harmonic distortion plus noise (THD+N) of 0.00067% (-103.5 dB). The proposed Class-D amplifier with 1.45 mA quiescent current shows a peak SNR (A-weighted) of 108 dB, the maximum output power of 3.1 W at 1% THD+N, and 89.5% efficiency with a 4 Ω load. The Class-D audio amplifier, which occupies the active area of 1.85 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> in a 0.153 μ m 1P5M CMOS process, can be operated from 3 V to 5.5 V.
Nutritional therapy in diabetes (1986)

The cornerstone of diabetes management is an appropriate diet. Various diets, including one low in carbohydrate, have been recommended in the past. The American Diabetes Association currently recommends a diet high in complex carbohydrate and fiber. The diet plan should be individualized. Caloric content is based on the patient's body build, weight, energy needs, and activity and may be adjusted according to individual eating habits, type of insulin regimen, and metabolic derangements. The proportion of caloric sources (fat, carbohydrate, protein) may be altered depending on the presence of secondary disorders. Several small daily meals, including a bedtime snack, are advised. Diabetic diets are often cost-effective, contrary to common belief. Patients should be encouraged to exercise to achieve optimum diabetic control. Active patient participation in the management program is an essential component of therapy.
An improved deep neural network model for job matching (2018)

Job matching which benefit job seekers, employees and employers is very important today. In this work, a deep neural network model is proposed to predict an employee's future career details, which includes position name, salary and company scale based on the online resume data. Like most NLP tasks, the input features are multi-field, non-sparse, discrete and categorical, while their dependencies are mostly unknown. Previous works were mostly focused on engineering, which resulted in a large feature space and heavy computation. To solve this task, we use embedding layers to explore feature interactions and merge two automatically learned features extracted from the resumes. Experimental results on over 70,000 real-word online resumes show that our model outperforms shallow models, like SVM and Random Forests, in effectiveness and accuracy.
High‐Throughput Mass‐Spectrometry Monitoring for Multisubstrate Enzymes: Determining the Kinetic Parameters and Catalytic Activities of Glycosyltransferases (2005)

A novel high-throughput screening (HTS) method with electrospray time-of-flight (ESI-TOF) mass spectrometry allows i) rapid and broad screening of multisubstrate enzyme catalytic activity towards a range of donor and acceptor substrates; ii) determination of full multisubstrate kinetic parameters and the binding order of substrates. Two representative glycosyltransferases (GTs, one common, one recently isolated, one O-glycosyltransferase (O-GT), one N-glycosyltransferase (N-GT)) have been used to validate this system: the widely used bovine beta-1,4-galactosyltransferase (EC 2.4.1.22), and the recently isolated Arabidopsis thaliana GT UGT72B1 (EC 2.4.1.-). The GAR (green/amber/red) broad-substrate-specificity screen, which is based on the mass ion abundance of product, provides a fast, high-throughput method for finding potential donors and acceptors from substrate libraries. This was evaluated by using six natural and non-natural donors (alpha-UDP-D-Glucose (UDPGlc), alpha-UDP-N-Acetyl-D-glucosamine (UDPGlcNAc), alpha-UDP-D-5-thioglucose (UDP5SGlc), alpha-GDP-L-fucose (GDPFuc), alpha-GDP-D-mannose (GDPMan), alpha,beta-UDP-D-mannose (UDPMan)) and 32 broad-ranging acceptors (sugars, plant hormones, antibiotics, flavonoids, coumarins, phenylpropanoids and benzoic acids). By using the fast-equilibrium assumption, KM, kcat and KIA were determined for representative substrates, and these values were used to determine substrate binding orders. These screening methods applied to the two very different enzymes revealed some unusual substrate specificities, thus highlighting the utility of broad-ranging substrate screening. For UGT72B1, it was shown that the donor specificity is determined largely by the nucleotide moiety. The method is therefore capable of identifying GT enzymes with usefully broad carbohydrate-transfer ability.
High-Efficiency Device Localization in 5G Ultra-Dense Networks: Prospects and Enabling Technologies (2015)

The deployment of future 5G ultra-dense small cell networks provides unprecedented opportunities to create an advanced localization system that meets the demands of future location-based services and functionalities. In this paper, we present technical enablers for obtaining location information of user nodes (UNs) in a network-centric manner. More specifically, we focus on signal properties, access node (AN) hardware and AN deployments in the envisioned 5G systems. Moreover, we provide illustrative examples of the expected localization performance and indicate how to efficiently predict the UN location. Finally, we offer insights into the utilization of location-awareness and location prediction, and show that it provides substantial benefits compared to existing radio networks.

Perturbations in the fibrinolytic pathway abolish cyst formation but not capillary-like organization of cultured murine endothelial cells (1994)

Fibrinolytic activity and its relation to morphogenesis was investigated in several transformed murine endothelial cell lines and primary cultures of endothelial cells. Two in vitro systems, fibrin gels and Matrigel (Collaborative Research, Bedford, MA), were used. Fibrin gels model a fibrin-rich extracellular matrix that frequently supports neovascularization in vivo, and Matrigel models the basement membrane surrounding quiescent endothelial cells in vivo. The transformed endothelial cell lines have higher levels of plasminogen activator (PA) mRNA than primary cultures of endothelial cells, and an increased PA-mediated proteolytic activity was correlated with formation of cysts in fibrin gels. Addition of neutralizing anti- urokinase antibodies, plasminogen depletion, or addition of a plasmin inhibitor prevented cyst formation. Addition of plasminogen restored the ability to form cysts in the plasminogen-depleted system. Normal endothelial cells organized into capillary-like structures in fibrin gels regardless of manipulations affecting the fibrinolytic pathway. In Matrigel, both transformed and primary cultures of endothelial cells rapidly formed a capillary-like network that was not affected by plasminogen depletion or addition of plasmin inhibitors. Thus, elements of the fibrinolytic pathway necessary for cyst formation are not critical in capillary-like structure formation on a reconstituted basement membrane. These results suggest that plasmin is essential for hemangioma formation but is not critical to the organizational behavior of normal endothelial cells.
Vernier Transceiver Architecture for Side-Lobe-Free and High-Entendue LiDAR (2018)

Radiopaque contrast media. XLIV - Preclinical studies with a new nonionic contrast agent. (1977)

L-5-alpha-hydroxypropionylamino-2,4,6-triiodoisophthalic acid di-(1,3-dihydroxy-2-propylamide), abbreviated Iopamidol, a new non-ionic water soluble contrast agent for angiography, myelography, ventriculography and for contrast reinforced computer-assisted axial tomography is described. Extensive preclinical testing showed favorable physico-chemical features of the new compound, low systemic toxicity, excellent cardiovascular and renal tolerability, very mild effects on the blood-brain barrier and on nervous tissue.
Dissolution rate of calcium sulfite hemihydrate in flue gas desulfurization processes (1986)

Abstract The rate of calcium sulfite dissolution in slurry scrubbers and hold tanks for flue gas desulfurization affects SO 2 absorption, limestone utilization and sulfite oxidation. The dissolution rates of calcium sulfite were measured by the pH‐state method. A mass transfer model was developed assuming that calcium sulfite particles behave as spheres in an infinite stagnant solution. The model combined with the Bechtel‐modified Radian solution equilibrium program successfully predicts calcium sulfite dissolution rates at pH 3.5 – 5.5, 23 and 55°C, 0.001 – 0.3 M Ca ++ and 2 – 25 mM dissolved sulfite. The effects of sulfate content in solids and liquids and particle size/shape were also studied. At conditions typical of flue gas desulfurization processes calcium sulfite dissolution was controlled by mass transfer, not surface reaction kinetics. Dissolution was fast at low pH and slowed near the equilibrium pH determined by dissolved Ca ++ and SO 3 = concentrations in the aqueous solutions, K sp of the CaSO 3 · 1/2H 2 O solids, and temperature. The presence of dissolved Mg ++ increased the equilibrium pH and enhanced the disolution rate. The presence of dissolved sulfate reduced the dissolution rate and the equilibrium pH. The effect of sulfate was not adequately described by the mass transfer model.

System performance gain by interference cancellation in WCDMA dedicated and high-speed downlink channels (2003)

A large number of the existing and planned 3G networks rely on the 3GPP WCDMA standard. Since the downlink of WCDMA systems is usually interference limited, interference cancellation algorithms that reduce the interference on the desired signal can significantly improve the system capacity. The system-level performance gain that can be achieved by interference cancellation on the terminal side is investigated. Two downlink channels are considered: the dedicated downlink channel, which is already part of the WCDMA standard, and the new high-speed downlink channel for packet-data support, which will be part of release 5 of the WCDMA standard. In the analysis, four receiver classes are compared: the standard RAKE receiver, a RAKE receiver with pilot subtraction, a linear MMSE equalizer, and a non-linear iterative successive cancellation algorithm. The resulting performance gains and the necessary implementation complexity are discussed.
Multiphase Interleaving Buck Converter with Input-Output Bypass Capacitor (2010)

As the number of transistors in microprocessors increases per Moore's Law their power requirement increases accordingly. This poses design challenges for their power supply module especially when microprocessors operate at sub voltage range. This paper presents a new multiphase topology that addresses these challenges. Laboratory tests on a hardware prototype of the topology shows improved performance compared to a commercially available power supply module.
Senescent cells: New target for an old treatment? (2017)

Many genotoxic chemotherapies have debilitating side effects and induce cellular senescence in normal tissues. Senescent cells acquire a pro-inflammatory phenotype which contributes to local and systemic inflammation. Eliminating senescent cells reduce several short- and long-term effects of the drugs, providing a new target to reduce the toxicity of anticancer treatments.
Surface micromachined solenoid inductors for high frequency applications (1997)

As operation frequencies and performance requirements of wireless devices increase, the resultant demands on the performance of passive components also increase. Miniaturization of inductive components for high frequency has been a key research area to address this issue; however, in general, miniaturized integrated inductors can suffer from low Q factors and/or self-resonant frequencies when compared to their discrete counterparts. The most popular geometries for integrated inductors have been meander types or spiral types, whereas most macro scale inductors are solenoid types. In this research, a modified geometry of a solenoid type inductor using a surface micromachining technique is proposed. This inductor has an air core for high frequency operation and an electroplated copper coil to reduce the series resistance. An important feature of the proposed inductor geometry is the introduction of an air gap between the substrate and the conductor coil in order to reduce the effects of the substrate dielectric constant. This air gap can be realized using a polyimide sacrificial layer and a surface micromachining technique. Therefore, the resulting inductor can have less substrate-dependent magnetic properties, less stray capacitance, and higher Q-factor. A preliminary measurement result shows that this inductor has high Q-factor and stable inductance over a wide range of operating frequency.
Reduction of the anti-cancer drug analogue cis,trans,cis-[PtCl2(OCOCH3)2(NH3)2] by L-cysteine and L-methionine and its crystal structure † (1999)

The complex cis,trans,cis-[PtCl2(OCOCH3)2(NH3)2] 1 has been synthesized as a simplified and more soluble model of the anticancer drug cis,trans,cis-[PtCl2(OCOCH3)2(NH3)(C6H11NH2)] (JM216). The crystal structure of 1 shows an octahedral co-ordination sphere around the PtIV with strong intramolecular and weak intermolecular hydrogen bonding. The kinetics of reduction of 1 by the divalent sulfur amino acids L-cysteine and L-methionine has been determined over a range of pH values by multinuclear NMR. The reduction is strongly pH dependent, being related to the protonation state of the amino acid and the basicity of the sulfur. Reduction rates are dramatically slower than for previous models of platinum(IV) drug systems.
Elevated Brain Serotonin Turnover in Patients With Depression (2008)

Brain serotonin turnover is elevated in unmedicated patients with MDD and is influenced by the 5-HTT genotype. The marked reduction in serotonin turnover following SSRI treatment and the accompanying improvement in symptoms suggest that high brain serotonin turnover may be a biological substrate of MDD.
Optical Spectra and Intensities of Nd3+ in YAlO3 (1971)

The optical absorption and emission spectra, fluorescence kinetics, and radiative and nonradiative transition probabilities of Nd3+ ions in YAlO3 are investigated. Measurements are presented of the energy levels, absorption and emission cross sections, linewidths as a function of temperature and Nd concentration, thermal line shifts, and fluorescence branching ratios. Judd-Ofelt intensity parameters for electric-dipole transition probabilities are derived from measurements of the absorption spectrum. Stimulated emission cross sections, absorption-band intensities, fluorescence quantum efficiency, possible excited-state absorption, and other properties of importance for YAlO3:Nd3+ laser action are discussed.
Anti-proliferative activity and cell cycle arrest induced by evodiamine on paclitaxel-sensitive and -resistant human ovarian cancer cells (2015)

Chemo-resistance is the main factor for poor prognosis in human ovarian epithelial cancer. Active constituents derived from Chinese medicine with anti-cancer potential might circumvent this obstacle. In our present study, evodiamine (EVO) derived from Evodia rutaecarpa (Juss.) Benth suppressed the proliferation of human epithelial ovarian cancer, A2780 and the related paclitaxel-resistant cell lines and did not cause cytotoxicity, as confirmed by the significant decline of clone formation and the representative alterations of CFDA-SE fluorescence. Meanwhile, EVO induced cell cycle arrest in a dose- and time-dependent manner. This disturbance might be mediated by the cooperation of Cyclin B1 and Cdc2, including the up-regulation of Cyclin B1, p27, and p21, and activation failure of Cdc2 and pRb. MAPK signaling pathway regulation also assisted in this process. Furthermore, chemo-sensitivity potential was enhanced as indicated in A2780/PTX(R) cells by the down-regulation of MDR-1 expression, accompanied by MDR-1 function suppression. Taken together, we confirmed initially that EVO exerted an anti-proliferative effect on human epithelial ovarian cancer cells, A2780/WT and A2780/PTX(R), induced G2/M phase cell cycle arrest, and improved chemo-resistance. Overall, we found that EVO significantly suppressed malignant proliferation in human epithelial ovarian cancer, thus proving to be a potential anti-cancer agent in the future.
