Evaluating the Effects of Electric and Magnetic Loading on the Performance of Single and Double Rotor Axial Flux PM Machines (2020)

Axial-flux permanent-magnet machines are used particularly in applications requiring a compact structure. Their disc-shaped topology and axial airgap have led to a variety of configurations including two popular ones: the yokeless and segmented armature (YASA), and the single-stator single-rotor or single-sided machine. In this study, a comprehensive comparative analysis of these configurations is conducted at different magnetic and electric loadings. It is found that at lower loadings, typically employed for air-cooled machines, the torque/ampere characteristics of the YASA machine are almost identical to those of a single-sided machine constructed with half the magnet volume. On the other hand, the single-sided machine outperforms the YASA machine when the magnet volumes in both machines are maintained equal. However, for higher electric loadings, the torque/ampere characteristics of the YASA machine droop significantly less than those of the single-sided machine. This article includes analytical estimations, which are verified with experimentally validated finite element analysis (FEA) simulations. In addition, the impacts of the armature reaction on saturation and the magnetic flux linkage, the magnet losses, and eddy current losses in both machines are also explored.
Advanced damage-free photomask cleaning for 45/32nm technology nodes (2008)

High particle removal efficiency (PRE) up to 99%+ without damage to sub-50 nm linewidth features has been demonstrated using a mixed fluid jet technology and sulfur-free chemistry. This high PRE was achieved with several types of deposited particles, including polystyrene latex spheres. Damage-free cleaning was demonstrated on binary and phase shift masks with Cr and MoSi structures. All masks were processed using the Tetra<sup>TM</sup> mask cleaning tool configured with the NanoDroplet<sup>TM</sup> mixed fluid jet technology.

Self‐splicing RNA and an RNA Enzyme in Tetruhymena1 (1987)

The RNA molecules transcribed from many eukaryotic genes are interrupted by intervening sequences, which are removed by a process called RNA splicing. One structurally related group of intervening sequences, the group I intervening sequences, are found in a variety of microorganisms. Some of these, including the group I intervening sequence from the ribosomal RNA precursor of Tetrahymena thermophila, have been shown to mediate their own splicing in an RNA-catalyzed reaction. Following its excision from the ribosomal RNA precursor, the Tetrahymena intervening sequence acts as an enzyme, cutting and rejoining RNA substrates.
Two‐dimensional separation of peptides using RP‐RP‐HPLC system with different pH in first and second separation dimensions (2005)

Two-dimensional high performance liquid chromatography is a useful tool for proteome analysis, providing a greater peak capacity than single-dimensional LC. The most popular 2D-HPLC approach used today for proteomic research combines strong cation exchange and reversed-phase HPLC. We have evaluated an alternative mode for 2D-HPLC of peptides, employing reversed-phase columns in both separation dimensions. The orthogonality of 2D separation was investigated for selected types of RP stationary phases, ion-pairing agents and mobile phase pH. The pH appears to have the most significant impact on the RP-LC separation selectivity; the greatest orthogonality was achieved for the system with C18 columns using pH 10 in the first and pH 2.6 in the second LC dimension. Separation was performed in off-line mode with partial fraction evaporation. The achievable peak capacity in RP-RP-HPLC and overall performance compares favorably to SCX-RP-HPLC and holds promise for proteomic analysis.
Nonlinear optimization framework for image-based modeling on programmable graphics hardware (2003)

Graphics hardware is undergoing a change from fixed-function pipelines to more programmable organizations that resemble general purpose stream processors. In this paper, we show that certain general algorithms, not normally associated with computer graphics, can be mapped to such designs. Specifically, we cast nonlinear optimization as a data streaming process that is well matched to modern graphics processors. Our framework is particularly well suited for solving image-based modeling problems since it can be used to represent a large and diverse class of these problems using a common formulation. We successfully apply this approach to two distinct image-based modeling problems: light field mapping approximation and fitting the Lafortune model to spatial bidirectional reflectance distribution functions. Comparing the performance of the graphics hardware implementation to a CPU implementation, we show more than 5-fold improvement.
Arthritis imaging using a near-infrared fluorescence folate-targeted probe (2005)

A recently developed near-infrared fluorescence-labeled folate probe (NIR2-folate) was tested for in vivo imaging of arthritis using a lipopolysaccharide intra-articular injection model and a KRN transgenic mice serum induction mouse model. In the lipopolysaccharide injection model, the fluorescence signal intensity of NIR2-folate (n = 12) and of free NIR2 (n = 5) was compared between lipopolysaccharide-treated and control joints. The fluorescence signal intensity of the NIR2-folate probe at the inflammatory joints was found to be significantly higher than the control normal joints (up to 2.3-fold, P < 0.001). The NIR2-free dye injection group showed a persistent lower enhancement ratio than the NIR2-folate probe injection group. Excessive folic acid was also given to demonstrate a competitive effect with the NIR2-folate. In the KRN serum transfer model (n = 4), NIR2-folate was applied at different time points after serum transfer, and the inflamed joints could be detected as early as 30 hours after arthritogenic antibody transfer (1.8-fold increase in signal intensity). Fluorescence microscopy, histology, and immunohistochemistry validated the optical imaging results. We conclude that in vivo arthritis detection was feasible using a folate-targeted near-infrared fluorescence probe. This receptor-targeted imaging method may facilitate improved arthritis diagnosis and early assessment of the disease progress by providing an in vivo characterization of active macrophage status in inflammatory joint diseases.
Optimization of photovoltaic power generation using a Measurement and Management Technology (MMT) platform (2010)

In this article we describe preliminary results for a general data acquisition and management platform applied to system level solar farm energy optimization. The system optimization takes into account weather, solar radiance, sky cloud coverage, and solar panel characteristics. Despite continuous improvement in photovoltaic (PV) systems, the generated power of many installations is underperforming due to factors like: light obstruction, orientation and tilt of the solar panels, variation in manufacturing and installation process and debris or soiling on the solar panels. To overcome the above challenges, we leverage the capabilities of an energy management analytic platform to monitor in real time the power generation from solar panels under real operating conditions. The generated power of the solar panel is correlated with predictive weather models where the influence of sky coverage, temperature and opacity of air are integrated in physical models to predict the solar panel performance. Furthermore, it is recognized that in large scale photovoltaics system the generated power is dependent on the performance of individual cells and solar panels. Analyzing spatial and temporal trends of individual solar panels and combining it with real time power performance enable an increased visibility in the PV system performance and optimization through power management of the individual solar panel.
Proteomic Characterization of Messenger Ribonucleoprotein Complexes Bound to Nontranslated or Translated Poly(A) mRNAs in the Rat Cerebral Cortex (2005)

Receptor-triggered control of local postsynaptic protein synthesis plays a crucial role for enabling long lasting changes in synaptic functions, but signaling pathways that link receptor stimulation with translational control remain poorly known. Among the putative regulatory factors are mRNA-binding proteins (messenger ribonucleoprotein, mRNP), which control the fate of cytosolic localized mRNAs. Based on the assumption that a subset of mRNA is maintained in an inactive state, mRNP-mRNA complexes were separated into polysome-bound (translated) and polysome-free (nontranslated) fractions by sucrose density centrifugation. Poly(A) mRNA-mRNP complexes were purified from a postmitochondrial extract of rat cerebral cortex by oligo(dT)-cellulose affinity chromatography. The mRNA processing proteins were characterized, from solution, by a nanoflow reverse phase-high pressure liquid chromatography-mu-electrospray ionization mass spectrometry. The majority of detected mRNA-binding proteins was found in both fractions. However, a small number of proteins appeared to be fraction-specific. This subset of proteins is by far the most interesting because the proteins are potentially involved in controlling an activity-dependent onset of translation. They include transducer proteins, kinases, and anchor proteins. This study of the mRNP proteome is the first step in allowing future experimentation to characterize individual proteins responsible for mRNA processing and translation in dendrites.

Calcium and cAMP activate different chloride channels in the apical membrane of normal and cystic fibrosis epithelia. (1991)

The genetic disease cystic fibrosis (CF) causes decreased Cl- transport in several epithelia. cAMP-dependent regulation of apical membrane Cl- channels is defective in CF airway epithelia; as a result, CF epithelia fail to secrete Cl-. In contrast, Ca(2+)-stimulated Cl- secretion is intact in CF airway epithelia and thus has the potential to bypass the CF Cl- secretory defect. For a Cl- channel to govern Cl- secretion, it must be located in the apical membrane. To specifically investigate apical membrane Cl- channels, we studied cells grown on permeable filter supports and measured Cl- currents across the apical membrane. We found that Ca2+ and cAMP activate different Cl- channels in the apical membrane. (i) Ca(2+)-activated Cl- channels were present in the apical membrane of airway but not in intestinal epithelia. (ii) cAMP- but not Ca(2+)-activated Cl- channels were defective in CF airway epithelia. (iii) Ca(2+)- but not cAMP-activated Cl- channels were blocked by 4,4'-diisothiocyanato-2,2'-stilbenedisulfonate. (iv) Ca(2+)- and cAMP-activated apical channels had different anion permeabilities. (v) An increase in both second messengers produced an additive increase in Cl- current. These results also explain the puzzling observation that Ca(2+)-stimulated Cl- secretion is defective in CF intestine: the Ca(2+)-activated Cl- channels that could circumvent the Cl- secretory defect in CF airway are missing from the apical membrane of intestinal epithelia.
Contributions of the nanovoid structure to the moisture absorption properties of epoxy resins (1998)

Epoxy resins absorb significant quantities of moisture, typically 1 to 7% by weight for various formulations, which can greatly compromise their physical properties. It is known that polarity of the epoxy is a significant factor in determining the ultimate moisture uptake. However, the contribution from molecular topology still remains vague. In this work, the effects of molecular topology are elucidated by synthesizing novel epoxies where the polarity is maintained constant but the topology is systematically altered. The molecular topology is quantified in part via Positron Annihilation Lifetime Spectroscopy (PALS) in terms of the nanometer-sized voids, or nanovoids, that are also commensurate with typical interchain distances. The nanovoids are separated into their absolute zero and thermally fluctuating fractions by performing PALS measurements over a wide range of temperatures. A strong correlation is observed between the absolute zero hole volume fraction and the ultimate moisture uptake. Although the correlation is clear, the absolute zero hole volume fraction alone is not sufficient to predict the ultimate moisture uptake, and network polarity must also be considered. It is surmised that the role of the nanovoids is to open the epoxy matrix and alleviate steric hindrances that may prevent a water molecule from associating with a polar group. © 1998 John Wiley & Sons, Inc.

A comprehensive optimized model for on-board solar photovoltaic system for plug-in electric vehicles: energy and economic impacts (2016)

Environmental concerns along with high energy demand in transportation are leading to major development in sustainable transportation technologies, not the least of which is the utilization of clean energy sources. Solar energy as an auxiliary power source of on-board fuel has not been extensively investigated. This study focuses on the energy and economic aspects of optimizing and hybridizing, the conventional energy path of plug-in electric vehicles (EVs) using solar energy by means of on-board photovoltaic (PV) system as an auxiliary fuel source. This study is novel in that the authors (i) modeled the comprehensive on-board PV system for plug-in EV; (ii) optimized various design parameters for optimum well-to-tank efficiency (solar energy to battery bank); (iii) estimated hybrid solar plug-in EVs energy generation and consumption, as well as pure solar PV daily range extender; and (iv) estimated the economic return of investment (ROI) value of adding on-board PVs for plug-in EVs under different cost scenarios, driving locations, and vehicle specifications. For this study, two months in two US cities were selected, which represent the extremities in terms of available solar energy; June in Phoenix, Arizona and December in Boston, Massachusetts to represent the driving conditions in all the US states at any time followed by assessment of the results worldwide. The results show that, by adding on-board PVs to cover less than 50% (around 3.2 m2) of the projected horizontal surface area of a typical passenger EV, the daily driving range could be extended from 3.0 miles to 62.5 miles by solar energy based on vehicle specifications, locations, season, and total time the EV remains at Sun. In addition, the ROI of adding PVs on-board with EV over its lifetime shows only small negative values (larger than −45%) when the price of electricity remains below $0.18/kWh and the vehicle is driven in low-solar energy area (e.g. Massachusetts in the US and majority of Europe countries). The ROI is more than 148% if the vehicle is driven in high-solar energy area (e.g. Arizona in the US, most Africa countries, Middle East, and Mumbai in India), even if the electricity price remains low. For high electricity price regions ($0.35/kWh), the ROI is positive and high under all driving scenarios (above 560%). Also, the reported system has the potential to reduce electricity consumption from grid by around 4.5 to 21.0 MWh per EV lifetime. A sensitivity analysis has been carried out, in order to study the impacts of the car parked in the shade on the results. Copyright © 2016 John Wiley & Sons, Ltd.
A Friction Compensation Method in Positioning Control of Nonresonant Ultrasonic Actuator-Driven Precise Stage (2006)

This research has aimed at the control system development of a non-resonant ultrasonic motor (SPIDER)-driven precision stage. SPIDER is newly developed as an actuator to achieve the positioning performance required for next generation. In this paper, friction compensation is firstly realized considering integral effect of controllers. Next, the compensation is achieved based on the adaptive friction observer. Moreover it is experimentally verified that the stick-slip phenomenon is prevented for an environmental change by the proposal technique, and a quick positioning in the scale resolution becomes possible.

Clinical Experience with Fludarabine and its Immunosuppressive Effects in Pretreated Chronic Lymphocytic Leukemias and Low-Grade Lymphomas (1995)

Fludarabine monophosphate (FAMP) is a new adenine nucleoside analogue with a promising efficacy in B-cell chronic lymphocytic leukemia (B-CLL) and low-grade non-Hodgkin lymphomas (NHLs). Here, the clinical experience and side effects with FAMP are reported in 77 patients with pretreated CLL (59 B-CLL, 2 T-CLL) and low-grade NHLs (9 immunocytic lymphomas including 5 Waldenström's macroglobulinaemia, 2 centrocytic (cc) and 5 centroblastic-centrocytic (cb-cc) NHLs). 70/77 patients are evaluable for response. All except 8 patients were pretreated with one to four different regimens and had progressive disease. FAMP was administered at a dosage of 25 mg/m2 daily for 5 days as 30 minute infusion every fifth week. Partial (PR) or complete remission (CR) was achieved in 38/56 (68%) and 3/56 (5%) of evaluable patients with CLL, respectively. In 7/8 (1 x CR, 6 x PR) evaluable patients with immunocytic lymphoma and in 3/6 (3 x PR) patients with cc or cb-cc lymphoma remissions were obtained. The probability of progression-free survival was 66% and the event-free survival was 25% and 22% at 12 and 18 months. The median progression-free survival until relapse or death, however, was only 7 months (2-20+). Major toxic effects included infections in 22 patients (grade 3 and 4 WHO), granulocytopenia (mainly grade 3) and nausea in 8 patients (mainly grade 1). 19/22 patients were in PR at the time of occurrence of infectious complications. Meanwhile, 14 patients died due to septicaemia, pneumonia or other infections. Nine patients developed severe septicaemia, 4 patients had pneumocystis carinii or aspergillus pneumonias. The high infection rate may not only be due to hypogammaglobulinaemia and granulocytopenia induced by FAMP but also to a remarkable decrease of CD4+ cells from a median of 2479 to 241 CD4+ cells/microliters after 6 cycles of FAMP. In one case a tumor lysis syndrome was observed. No CNS toxicity was noted. It is concluded that FAMP is effective even in patients with advanced CLL and low-grade NHLs refractory to multiple chemotherapy regimens. However, FAMP has a marked suppressive effect on granulocytes and T-lymphocytes, predominantly CD4+ lymphocytes.
Burst Structure of Jupiter's Decametric Radiation. (1966)

The structure of the bursts of decametric radiation from Jupiter has been investigated using chart speeds up to 50 mm/sec and time constants down to 5 msec. To make identification of short pulses more certain observations have been made of the left- and right- handed components of the radiation at 16, 18, and 22 Mc/sec, and of the total power at 14 Mc/sec. The polarization measurements have been made using a hybrid ring and separate receivers for the two senses of polarization to avoid the uncertainties which might arise from switching techniques. In addition, the total power was recorded at 18 Mc/sec by using an array having a null in the direction of Jupiter. This antenna served as a monitor to identify static pulses which could have the same appearance as millisecond pulses from Jupiter. A phase-switching interferometer was operated at 18 Mc/sec throughout observing periods as an additional means of identifying that Jupiter was active during the period. Several distinct forms of burst structure have been observed. In particular pulses as short as or shorter than 10 msec, with different forms of grouping, have been observed on numerous occasions. 77 These pulses appear to be associated with ``sources B and C rather than "source" A on Jupiter. Different forms of burst structure may occur on different frequencies at the same time, and on occasions different polarizations occur simultaneously on different frequencies.
