Effect of CeOx Crystallite Size on the Chemical Stability of CeOx Nanoparticles (2014)

CeOx is an excellent free radical scavenger to improve polymer electrolyte membrane durability. However, this metal oxide will dissolve during accelerated stress testing (AST), with the resulting cations transporting to the cathode catalyst layer (CCL) leading to performance reduction/degradation of the PEMFC. Controlling the rate of CeOx dissolution is therefore of great importance, as it may be possible to maintain sufficient Ce cations for free radical scavenging while minimizing the impact of these cations on the CCL. Here the effect of CeOx crystallite size on CeOx dissolution was investigated. Three CeOx additives were prepared having crystallite sizes of 6, 13, or 25 nm. An ex-situ method was used to evaluate the chemical stability of these three CeOx samples, as well as one commercially available CeOx. It was determined that surface area, rather than crystallite size, is the best predictor of chemical stability. In-situ membrane electrode assembly AST cycling was then performed, demonstrating that when low loadings of CeOx (0.006 mg/cm2) are used, the ex-situ method correctly predicts trends in end of life (EOL) performance. Finally, it is shown that increasing the anode RH during AST cycling leads to significantly higher EOL performance losses.
Mechanically reconfigurable antennas using an anisotropic carbon‐fibre composite ground (2013)

The authors present reconfigurable antennas based on anisotropic reinforced continuous carbon fibre composite (RCCFC) material. By the rotation of the anisotropic RCCFC ground plane, the current distribution can be changed to select a desirable mode of resonance and suppress unwanted modes. Hence, the RCCFC ground plane behaves as a mode filter in the proposed reconfigurable antennas. Several types of probe‐fed reconfigurable microstrip‐patch antennas are presented, including the RCCFC conductivity characteristics, the principle of reconfigurable operation and the simulated and measured performance. The outstanding mechanical strength of RCCFC materials along with the promising radiation characteristics of these reconfigurable antennas make them good candidates for radio cognitive and military applications.

QueRIE: Collaborative Database Exploration (2014)

Interactive database exploration is a key task in information mining. However, users who lack SQL expertise or familiarity with the database schema face great difficulties in performing this task. To aid these users, we developed the QueRIE system for personalized query recommendations. QueRIE continuously monitors the user's querying behavior and finds matching patterns in the system's query log, in an attempt to identify previous users with similar information needs. Subsequently, QueRIE uses these “similar” users and their queries to recommend queries that the current user may find interesting. In this work we describe an instantiation of the QueRIE framework, where the active user's session is represented by a set of query fragments. The recorded fragments are used to identify similar query fragments in the previously recorded sessions, which are in turn assembled in potentially interesting queries for the active user. We show through experimentation that the proposed method generates meaningful recommendations on real-life traces from the SkyServer database and propose a scalable design that enables the incremental update of similarities, making real-time computations on large amounts of data feasible. Finally, we compare this fragment-based instantiation with our previously proposed tuple-based instantiation discussing the advantages and disadvantages of each approach.
Influenza hemagglutinin membrane anchor (2018)

Viruses with membranes fuse them with cellular membranes, to transfer their genomes into cells at the beginning of infection. For Influenza virus, the membrane glycoprotein involved in fusion is the hemagglutinin (HA), the 3D structure of which is known from X-ray crystallographic studies. The soluble ectodomain fragments used in these studies lacked the "membrane anchor" portion of the molecule. Since this region has a role in membrane fusion, we have determined its structure by analyzing the intact, full-length molecule in a detergent micelle, using cryo-EM. We have also compared the structures of full-length HA-detergent micelles with full-length HA-Fab complex detergent micelles, to describe an infectivity-neutralizing monoclonal Fab that binds near the ectodomain membrane anchor junction. We determine a high-resolution HA structure which compares favorably in detail with the structure of the ectodomain seen by X-ray crystallography; we detect, clearly, all five carbohydrate side chains of HA; and we find that the ectodomain is joined to the membrane anchor by flexible, eight-residue-long, linkers. The linkers extend into the detergent micelle to join a central triple-helical structure that is a major component of the membrane anchor.
Observation of single-cell fluorescence spectra in laser flow cytometry (1996)

We report the first demonstration of directly recording fluorescence spectra of single cells in flow cytometry. An intensified, 512-element photodiode array was used in conjunction with a dispersing prism to capture the fluorescence emission spectra of Coulter ImmunoCheck calibration beads and Dictyostelium discoideum spores stained with the indocarbocyanine derivative CY3, fluorescein isothiocyanate, or R-phycoerythrin. The demonstration was made feasible by enhancing the signal-to-noise ratio of the detection process by using a fast gating technique applied to the detector. Results show that the complete fluorescence spectra of individual stained cells contain information that is normally not captured by conventional flow cytometers. By using the spectrographic flow cytometer, all this information is recorded, allowing small features and shifts in the fluorescence spectra of labelled particles to be studied.

An oscillator whose frequency is amplitude dependent can be controlled by a drive whose frequency sweeps through a resonance with the oscillator's fundamental frequency. This phenomenon is called autoresonance, and has been previously investigated for drives with frequencies near the oscillator's fundamental or subharmonic frequencies. This paper examines autoresonance for drives at twice the fundamental frequency, i.e, second harmonic autoresonance. The l=1 diocotron mode in pure-electron plasmas, a very high Q nonlinear oscillator, is the focus of the paper. The theory for this oscillator is derived, and compared to experimental results. The results can be generalized to any Duffing-like driven nonlinear oscillator in which the coupling between the drive and the oscillator depends at least weakly on the oscillator amplitude.
Lane segmentation in traffic monitoring systems based on probability map (2010)

This paper describes an approach for lane segmentation in traffic monitoring systems based on probability map extracted form vehicles movement information. In traffic monitoring system, the region that a vehicle passes through might belong to a certain lane. The more vehicles pass through a certain region, the more likely it belongs to a certain lane, and then we can get probability map of the lane. The regions belong to the same lane must have the same probability. So, we can segment the probability map to extract the segmentation of the lanes. Firstly, we use Gaussian background modeling algorithm to extract the motion regions and background image, then the probability map is built by moving vehicles. The road areas acquired by region growing algorithm based on moving vehicles are used to eliminate the disturbance outside of road areas. The straight-lines about lane boundaries can be extracted by using Hough transform on the edge image of probability map. Finally we divide a road area into several lane regions by fusing the trajectories information of vehicles acquired by KLT method. The experiments in deferent scenes show the efficiency and robustness of the proposed approach.
Stimulation of the activity of horseradish peroxidase by nitrogenous compounds. (1988)

A variety of nitrogenous compounds broaden the activity versus pH profile for the peroxidation of dianisidine catalyzed by horseradish peroxidase (HRP), but not by myeloperoxidase, chloroperoxidase, Escherichia coli hydroperoxidase I, methemoglobin, or microperoxidases. The peroxidation of dianisidine catalyzed by cytochrome c peroxidase was affected by the nitrogenous compounds, but to a lesser extent than was the action of HRP. The peroxidations of a variety of phenols by HRP exhibited broad activity versus pH profiles and were unaffected by the nitrogenous compounds. The energy of activation for the peroxidation of dianisidine by HRP was unaffected by changes of pH in the range 6.5-8.5 and was unchanged by the presence of the nitrogenous compounds. The nitrogenous compounds markedly increased Vm for the peroxidation of dianisidine by HRP, but did not change the slope of Lineweaver-Burk plots of kinetic data. These results are accommodated by a mechanism in which nitrogenous compounds hydrogen-bond to the distal histidine of HRP and in so doing raise its pK alpha. Since the acid form of the distal histidine is thought to facilitate peroxidations catalyzed by HRP by hydrogen bonding to the ferryl oxygen of compound II, raising its pK alpha broadens the activity versus pH profile for the peroxidation of anilino substrates, such as dianisidine. We propose that phenolic substrates hydrogen-bond directly to the ferryl oxygen, thus displacing the distal histidine and eliminating the possibility of being influenced by nitrogenous compounds.
Silica-based integrated optic Mach-Zehnder multi/demultiplexer family with channel spacing of 0.01-250 nm (1990)

A Mach-Zehnder (MZ) interferometer design is presented for application to wavelength-division multiplexed/frequency division multiplexed (WDM/FDM) systems. A variety of integrated-optic devices with low loss and low crosstalk, using silica-based waveguides, are demonstrated. MZ interferometers operate as multi/demultiplexers or frequency-selection switches. The channel spacing is determined by the waveguide arm length difference, and a spacing range of 1 GHz to 36 THz, corresponding to a wavelength spacing of 0.008-250 nm, is achieved. The devices for the WDM region have low fiber-to-fiber loss of 0.5 dB, and the devices for the FDM region have higher losses of 2-5 dB. Crosstalk of less than -15 dB was obtained for all the devices. A 5-GHz-spaced 16-channel frequency selection switch and a 10-GHz-spaced eight-channel multi/demultiplexer were also fabricated with a total loss of 5 dB and total crosstalk of -10 dB or less.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
MicroRNA Profiling During Neural Differentiation of Induced Pluripotent Stem Cells (2019)

MicroRNAs (miRNA) play an essential role in the regulation of gene expression and influence signaling networks responsible for several cellular processes like differentiation of pluripotent stem cells. Despite several studies on the neurogenesis process, no global analysis of microRNA expression during differentiation of induced pluripotent stem cells (iPSC) to neuronal stem cells (NSC) has been done. Therefore, we compared the profile of microRNA expression in iPSC lines and in NSC lines derived from them, using microarray-based analysis. Two different protocols for NSC formation were used: Direct and two-step via neural rosette formation. We confirmed the new associations of previously described miRNAs in regulation of NSC differentiation from iPSC. We discovered upregulation of miR-10 family, miR-30 family and miR-9 family and downregulation of miR-302 and miR-515 family expression. Moreover, we showed that miR-10 family play a crucial role in the negative regulation of genes expression belonging to signaling pathways involved in neural differentiation: WNT signaling pathway, focal adhesion, and signaling pathways regulating pluripotency of stem cells.
Flywheel energy-storage-and-conversion system for photovoltaic applications. Final report (1982)

Efforts to develop a magnetically suspended solar photovoltaic flywheel energy storage unit for residential applications are discussed. A 1/10-scale prototype flywheel unit, which stores 1 kWh of energy in a 400-pound, 15-inch-diameter steel rotor at a maximum of 15,000 RPM, was designed, constructed and tested. The 1/10-scale prototype unit was based on a full-scale, 40-kWh residential flywheel design and was a total system in that it included all the electrical features needed for a complete interface between a photovoltaic array and a residential or utility load. Design features of the unit, such as its magnetic bearing, motor-generator, rotor and output power-conditioning equipment, are described and test results are presented. Manufacturing cost studies of the full-scale, 40-kWh residential flywheel system are reported along with user worth studies of flywheel systems in the Northeast and Southwest. The 1/10-scale prototype test setup was modified into an advanced prototype flywheel test unit. The advanced prototype unit consisted of a simplified, two-element magnetic bearing, to reduce projected manufacturing costs, and an available GFE advanced composite rotor of 24-inch diameter and 123-pound weight and storing 1-kWh at 15,000 RPM. An objectives of this work was to gain experience in the use of such advanced rotors on magnetic suspension. The structural flexibility inherent in the GFE composite rotor was found to require redesign of the axial servo loop control system to obtain magnetic levitation. The magnetically suspended, advanced composite rotor was then spin tested at rotational speeds up to 12,000 RPM. A new full-scale design for a 20-kWh, two-element, advanced flywheel system was prepared. Simulation studies of utility-interactive residential flywheel systems are reported.
Theano: Deep Learning on GPUs with Python (2012)

In this paper, we present Theano1, a framework in the Python programming language for defining, optimizing and evaluating expressions involving high-level operations on ten-sors. Theano offers most of NumPy’s functionality, but adds automatic symbolic differen-tiation, GPU support, and faster expression evaluation. Theano is a general mathematical tool, but it was developed with the goal of facilitating research in deep learning. The Deep Learning Tutorials2 introduce recent advances in deep learning, and showcase how Theano makes such algorithms compact, elegant, and fast.
Preparation of a Cell-Free, Isobutene-Forming System from <i>Rhodotorula minuta</i> (1988)

The cell-free isobutene-forming system of Rhodotorula minuta IFO 1102 was prepared. This system consisted of isovaleric acid, NADPH, and a cell extract. The maximal activity obtained by using the described cell-free system was 17 nl/mg of protein per h. It appears that this cell-free isobutene-forming system operates in living cells of R. minuta.
A Stability Indicating RP-HPLC Method for Simultaneous Determination of Ibuprofen and Famotidine (2016)

A stability indicating gradient RP-HPLC method is developed for simultaneous determination of ibuprofen and famotidine. Separation of degradants, ibuprofen and famotidine was carried out on Qualisil BDS C8 column (250 × 4.6 mm, 5 µm) using a mobile phase gradient consisting of methanol and water pH 3.0 at a flow rate of 1 mL/min. The detection and reference wavelengths were set at 263 nm (4 nm bandwidth) and 360 nm (80 nm bandwidth), respectively. Intentional degradation of ibuprofen and famotidine was attempted at stress condition of hydrolytic (refluxed at 80oC for 1 h), acid (5M HCl, refluxed at 80oC for 1 h), base (5M NaOH, refluxed at 80oC for 1 h), oxidation (15% H2O2, for 6 h at 30 oC) and sunlight (exposed for 4 h). Degradants were eluted up to ~ 26 min whereas famotidine and ibuprofen shows retention at 6.34 ± 1.53 and 21.76 ± 0.38 min respectively. Drug-drug interaction study was also performed. The proposed method was able to separate the formed sulfamide impurity which is a major degradation product of famotidine - ibuprofen combination mixture when kept at accelerated condition (40oC ± 75% RH for 30 days). The method obeys Beer’s law in the concentration range of 3-21 µg/mL for ibuprofen (r2=0.9998) and 0.1-0.7 µg/mL for famotidine (r2=0.9999). The assay result of synthetic mixture was found to be 99.13 ± 0.14 and 100.73 ± 0.57 for ibuprofen and famotidine, respectively. The proposed method was validated as per ICH Q2 (R1) analytical method validation guidelines. The percentage recovery was found to be 96.55 ± 1.83 and 102.83 ± 0.85 for ibuprofen and famotidine, respectively. The results of present study clearly shown that the proposed method was specific as ibuprofen and famotidine were estimated in presence of their acidic, alkaline, oxidative, hydrolytic and photolytic degradation products and it may be effectively applied for estimating the content of ibuprofen and famotidine in pharmaceutical formulation.
Optimal double-gate MOSFETs: symmetrical or asymmetrical gates? (2003)

Due to their near-ideal intrinsic features, double-gate (DG) MOSFETs (with thin, fully depleted (FD) Si-film (SOI) bodies) are of interest for possible future CMOS IC applications with L/sub eff/ approaching the lateral scaling limit (/spl sim/20 nm) (Fossum and Chong, 1998; Wong et al. 1998). Much of this interest stems from the two-channel property of the symmetrical-gate DG device and the implied higher current drive. More important, we believe, is the electrical coupling of the two gates through the FD Si film. This coupling underlies the inherent suppression of SCEs and the excellent subthreshold slope, which translate to high I/sub on//I/sub off/ ratios. In fact, as we show in this paper, the coupling can be exploited more in asymmetrical-gate DG MOSFETs (Fossum and Chong, 1998; Tanaka et al. 1994) than in symmetrical ones. We rely on numerical device simulations, using MEDICI and its hydrodynamic-transport option, and SOISPICE circuit simulations, using the UFSOI/FD MOSFET model (Fossum et al. 1998), to convey insight regarding performance and optimal design of DG MOSFETs and to reveal the inherent superiority of asymmetrical gates.
A dual damascene hard metal capped Cu and Al-alloy for interconnect wiring of ULSI circuits (2002)

This paper extends the application of hard-capped low resistivity metal damascene technology to submicron ULSI circuits utilizing a variety of hard and soft layers which are difficult to etch by conventional RIE process. The structure results in excellent yields, low via resistance, good corrosion and electromigration resistance by maintaining the planarity at all levels. Also the wear resistance of the soft layer, normally difficult to achieve, is significantly improved by a hard cap during damascene. The reliability, metal comb-serpentine shorts, opens and via resistances and fill properties of this technique using pitches down to 0.6 /spl mu/m are evaluated and "real life" product wafers with 1.0 /spl mu/m pitch are fabricated in the manufacturing environment. The example of this combination is the use of B/sub 1Cu/B/sub 2CVD W (where B/sub 1/ and B/sub 2/ are diffusion barriers chosen from PVD Ti/Cr-CrO/sub x/, Ti, Ti/Ta sandwich layers) and B/sub 3Al-alloy/B/sub 4CVD W where (B/sub 3/ and B/sub 4/ are diffusion barrier chosen from PVD Ti/TiN, Ti, Ti/W layers).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Evolution of Cu Electro-Deposition Technologies for 45nm and Beyond (2006)

As device geometry continues to diminish, the requirement of reliable copper metallization of narrow geometries becomes very challenging. The physical, electrical, reliability and manufacturability aspects of Cu electro-deposition (ECD) require full characterization for future generations. This paper will address the key challenges of ECD modules and several some possible solutions through proper optimizations of ECD process. The extendibility of ECD beyond 45 nm-node technologies was discussed
