New Insights into the Viscosity of Polymer-Based In-Situ Gelled Acids (2009)

Abstract Diversion techniques must be employed to remove all the damage from the entire producing interval. Diversion in carbonates is more difficult than in sandstones because of the ability of acid to significantly increase the permeability in carbonates as it reacts in the pore spaces and flow channels of matrix. The apparent viscosity of the in situ gelled acid based on polymer plays a key role in diversion because it creates a viscosity differential in treated and untreated zones. An extensive literature survey and field data, there is no agreement on the effectiveness of this acid system. Therefore , this study was conducted to better understand this acid system and determine factors that impact its viscosity build-up. Three commercially available in-situ acids were examined. The effect of salts, iron contamination on the apparent viscosity of these acids was examined. Several new findings were identified, including: Polymer and other additives were separated out of the acid when these acids were prepared in high salinity water. Preparing the in-situ gelled acid with saline water decreased the viscosity of the acid in live and neutralized conditions. Concentrated HCl solutions produced high concentrations of calcium chloride that reduced the viscosity of the acid system. Therefore, in-situ gelled acids that are based on the polymer should be used at low HCl concentrations (3-5 wt% HCl). Sodium, calcium or ferric chlorides reduced the apparent viscosity of live acids. A brown precipitate was noted during the neutralization of acid systems that contained Fe(III) even in the presence of the recommend concentration of iron control agents.
Introduction: Importance of Mg in physiology and medicine and the need for ion selective electrodes (1994)

Mg is a co-factor in more than 325 enzyme systems in cells and is the second most abundant intracellular cation after K. It is important in numerous physiologic and homeostatic functions such as hormone-receptor binding, gating of Ca2+ channels, transmembrane flux of ions, regulation of adenylate cyclase, Ca(2+)-Ca(2+) release, muscle contraction, cardiac excitability, neuronal activity, control of vasomotor tone and neurotransmitter release, to name a few. Serum total Mg measurements suggests this extracellular cation is often lowered in many hospitalized patients. It appears to be greatly depleted in normal food preparation and processing. Its daily intake has been declining steadily in the USA from where it was about 500 mg/day, at the turn of the century, to where it is now about 175-225 mg/day. Most mammals exhibit very similar levels of extracellular Mg, including humans. This might suggest that total Mg measurements on serum or plasma aren't sensitive blood variables or analytes to reflect what may be going on in the body at the cellular level. Mg exists in several forms in the blood, but the ionized, free Mg is probably the most physiologically important fraction, thus pointing to a need for sensitive, specific ion selective electrodes. Our studies, so far, suggest that ISE's can be designed which will work equally well on whole blood, serum and plasma to measure IMg2+ in healthy and diseased subjects.
Cell-to-cell activity prediction for smart cities (2016)

In this paper, we analyze data from a large mobile phone provider in Europe, pertaining to time series of aggregate communication volume A <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">i,j</sub> (t) > 0 between cells i and j, for all pairs of cells in a city over a month. We develop a methodology for predicting the future (in particular whether two cells will talk to each other A <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">i,j</sub> (t) > 0) based on past activity. Our data set is sparse, with 80% of the values being zero, which makes prediction challenging. We formulate the problem as binary classification and, using decision trees and random forests, we are able to achieve 85% accuracy. By giving higher weight to false positives, which cost more to network operators, than false negatives, we improved recall from 40% to 94%. We briefly outline potential applications of this prediction capability to improve network planning, green small cells, and understanding urban ecology, all of which can inform policies and urban planning.
Optimized architecture and design of an output-queued CMOS switch chip (2002)

Traditional improvements in packet switch architecture are aimed at increasing switch performance in terms of utilization, fairness and QoS. This paper focuses on improving the architecture to achieve implementation feasibility of terabit aggregate data rates while maintaining such performance. Terabit class shared-memory switch chips are simple in concept but are a challenge to build due to the memory speed requirements and the complexity of wiring needed to connect these memories. Using a property of the combined shared memory and virtual output queuing switch architecture and a property of SRAMs, a new architecture is derived that enables construction of a terabit class switch fabric.
Domain Adaptation of Recurrent Neural Networks for Natural Language Understanding (2016)

The goal of this paper is to use multi-task learning to efficiently scale slot filling models for natural language understanding to handle multiple target tasks or domains. The key to scalability is reducing the amount of training data needed to learn a model for a new task. The proposed multi-task model delivers better performance with less data by leveraging patterns that it learns from the other tasks. The approach supports an open vocabulary, which allows the models to generalize to unseen words, which is particularly important when very little training data is used. A newly collected crowd-sourced data set, covering four different domains, is used to demonstrate the effectiveness of the domain adaptation and open vocabulary techniques.
Through-the-coating femtosecond laser inscription of very short fiber Bragg gratings for acoustic and high temperature sensing applications (2017)

Very short Type I and Type II Bragg gratings, on the order of 100 µm in length, are written through the protective polyimide coating of high NA and standard single mode silica optical fibers with infrared femtosecond pulses and a phase mask. By exploiting the transverse walk-off of apertured diffracted beams produced by the phase mask and a slit placed proximate the mask, complex grating structures are fabricated and characterized. These gratings are suitable for structural health monitoring based on acoustic measurements or localized high-temperature measurements.

Schiff Base as Additive for Preventing Gas Evolution in Li4Ti5O12-Based Lithium-Ion Battery (2017)

Lithium titanium oxide (Li<sub>4</sub>Ti<sub>5</sub>O<sub>12</sub>)-based electrodes are very promising for long-life cycle batteries. However, the surface reactivity of Li<sub>4</sub>Ti<sub>5</sub>O<sub>12</sub> in organic electrolytes leading to gas evolution is still a problem that may cause expansion of pouch cells. In this study, we report the use of Schiff base (1,8-diazabicyclo[5.4.0]undec-7-ene) as an additive that prevents gas evolution during cell aging by a new mechanism involving the solid electrolyte interface on the anode surface. The in situ ring opening polymerization of cyclic carbonates occurs during the first cycles to decrease gas evolution by 9.7 vol % without increasing the internal resistance of the battery.
A Dual-Axis Liquid-Rate Microgyroscope Using Electro-Conjugate Fluid (2010)

The dual-axis liquid-rate gyroscope using Electro-Conjugate Fluid (ECF) proposed here follows a previously proposed single-axis liquid-rate gyroscope using ECF [1], a dielectric “smart fluid” generating a powerful jet flow (ECF jet) under a strong Direct-Current (DC) electric field. Although the proposed gyroscope’s sensing principle is based on that of a conventional gas rate sensor [2-4], the gyroscope itself is much more sensitivity because its density is generally higher than that of a gas. The gyroscope is more suitable for a microsensor than a gas rate sensor having a pump with piezoelectric actuator because the proposed gyroscope’s pump consists of a pair of tiny electrodes. We fabricated a 40×40×21 mm 3 dual-axis liquid-rate gyroscope prototype applying a single-axis liquid-rate microgyroscope and confirmed performance in experiments. Scale factors for the X and Y -axes measured in the gyroscope are -24 mV/°/s and -21 mV/°/s. Experimental results confirmed the dual-axis liquid-rate gyroscope potential.

Poly(vinyl alcohol) Reinforced and Toughened with Poly(dopamine)-Treated Graphene Oxide, and Its Use for Humidity Sensing (2014)

Poly(dopamine)-treated graphene oxide/poly(vinyl alcohol) ("dG-O/PVA") composite films were made and characterized. G-O was modified with poly(dopamine) in aqueous solution and then chemically reduced to yield poly(dopamine)-treated reduced G-O. A combination of hydrogen bonding, strong adhesion of poly(dopamine) at the interface of PVA and G-O sheets, and reinforcement by G-O resulted in increases in tensile modulus, ultimate tensile strength, and strain-to-failure by 39, 100, and 89%, respectively, at 0.5 wt % dG-O loading of the PVA. The dG-O serves as a moisture barrier for water-soluble PVA, and the dG-O/PVA composite films were shown to be effective humidity sensors over the relative humidity range 40-100%.
Degrees of Freedom Region for an Interference Network With General Message Demands (2012)

We consider a single-hop interference network with <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">K</i> transmitters and <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">J</i> receivers, all having <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">M</i> antennas. Each transmitter emits an independent message and each receiver requests an arbitrary subset of the messages. This generalizes the well-known <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">K</i> -user <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">M</i> -antenna interference channel, where each message is requested by a unique receiver. For our setup, we derive the degrees of freedom (DoF) region. The achievability scheme generalizes the interference alignment schemes proposed by Cadambe and Jafar. In particular, we achieve general points in the DoF region by using multiple base vectors and aligning all interferers at a given receiver to the interferer with the largest DoF. As a byproduct, we obtain the DoF region for the original interference channel. We also discuss extensions of our approach where the same region can be achieved by considering a reduced set of interference alignment constraints, thus reducing the time-expansion duration needed. The DoF region for the considered system depends only on a subset of receivers whose demands meet certain characteristics. The geometric shape of the DoF region is also discussed.
Synthesis and Biological Evaluation of Pyrimidine-Based Dual Inhibitors of Human Epidermal Growth Factor Receptor 1 (HER-1) and HER-2 Tyrosine Kinases (2012)

A novel series of N(4)-(3-chlorophenyl)-5-(oxazol-2-yl)pyrimidine-4,6-diamines were synthesized and evaluated as dual inhibitors of HER-1/HER-2 tyrosine kinases. In contrast to the currently approved HER-2-targeted agent (lapatinib, 1), our irreversible HER-1/HER-2 inhibitors have the potential to overcome the clinically relevant and mutation-induced drug resistance. The selected compound (19a) showed excellent inhibitory activity toward HER-1/HER-2 tyrosine kinases with selectivity over 20 other kinases and inhibited the proliferation of both cancer cell types: lapatinib-sensitive cell lines (SK-Br3, MDA-MB-175, and N87) and lapatinib-resistant cell lines (MDA-MB-453, H1781, and H1975). The excellent pharmacokinetic profiles of 19a in mice and rats led us to further investigation of a novel therapeutic agent for HER-2-targeting treatment of solid tumors, especially HER-2-positive breast/gastric cancer and HER-2-mutated lung cancer.
A Survey of Uncertain Data Clustering Algorithms (2018)

This chapter provides a survey of clustering algorithms for uncertain data. It discusses mixture model clustering of uncertain data and describes density-based clustering algorithms for uncertain data. Mixture model clustering is a popular method for clustering deterministic data, and it models the clusters in the underlying data in terms of a number of probabilistic parameters. Density-based methods are very popular in the deterministic clustering literature, because of their ability to determine clusters of arbitrary shapes in the underlying data. The work in designs methods for speeding up distance computations for the clustering process. The microclustering model was first proposed in for large data sets and subsequently adapted in for the case of deterministic data streams. In the case of the standard clustering problem, the main effect of uncertainty is the impact on the distance computations. The interplay between the clustering of the values and the level of uncertainty may affect the subspaces which are most optimal for the clustering process.

Temporal measurement of plasma density variations above a semiconductor bridge (SCB) (1995)

The plasma density variations above a semiconductor bridge (SCB) device employing a capacitor discharge firing set have been measured in vacuum (/spl les/10/sup -5/ torr). A novel diagnostic technique using a microwave resonator probe was used to measure the resultant plasma density variations as a function of time. This method is superior to Langmuir probes in this application because Langmuir probe measurements are affected by sheath effects, small bridge area, and unknown fraction of multiple ions. Our experimental results indicate that the plasma density is observed to increase to a peak value of 5.5/spl times/ 10/sup 11/ cm/sup -3/ and decay exponentially with time, which is consistent with diffusion dominating the plasma transport. The time needed for reaching the peak plasma density is about 1.6 /spl mu/s, which is the duration of the late time discharge of an SCB device.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Can small animal imaging accelerate drug development? (2002)

Better mechanistic understanding of disease through mapping of the human and mouse genomes enables rethinking of human infirmity. In the case of cancer, for example, we may begin to associate disease states with their underlying genetic defects rather than with the organ system involved. That will enable more selective, nontoxic therapies in patients who are genetically predisposed to respond to them. Because one of the major goals of molecular imaging research is to interrogate gene expression noninvasively, it can impact greatly on that process. Most of molecular imaging research is undertaken in small animals, which provide a conduit between in vitro studies and human clinical imaging. We are fortunate to be able to manipulate small animals genetically, and to have increasingly better models of human disease. The ability to study those animals noninvasively and quantitatively with new, high-resolution imaging devices provides the most relevant milieu in which to find and examine new therapies.

System-wide Analysis of the T Cell Response (2016)

The T cell receptor (TCR) controls the cellular adaptive immune response to antigens, but our understanding of TCR repertoire diversity and response to challenge is still incomplete. For example, TCR clones shared by different individuals with minimal alteration to germline gene sequences (public clones) are detectable in all vertebrates, but their significance is unknown. Although small in size, the zebrafish TCR repertoire is controlled by processes similar to those operating in mammals. Thus, we studied the zebrafish TCR repertoire and its response to stimulation with self and foreign antigens. We found that cross-reactive public TCRs dominate the T cell response, endowing a limited TCR repertoire with the ability to cope with diverse antigenic challenges. These features of vertebrate public TCRs might provide a mechanism for the rapid generation of protective T cell immunity, allowing a short temporal window for the development of more specific private T cell responses.
Joint mitigation of nonlinearity and modulator imperfections in dual‐band concurrent transmitter using neural networks (2013)

Reported, for the first time is a predistortion scheme for a concurrent dual‐band transmitter with a dual‐band concurrent Doherty power amplifier in the presence of modulator I/Q imbalance and DC offsets. Inverse PA modelling for predistortion is achieved using real valued time delayed neural networks. The model has been validated for a 10 W GaN based dual‐band concurrent Doherty power amplifier for wideband code division multiple access signals at 1960 and 3500 MHz, respectively, and an adjacent channel power ratio improvement of 18 dB is reported.
