Glutamine transaminase K and cysteine S-conjugate β-lyase activity stains (1991)

An activity stain to detect glutamine transaminase K subjected to nondenaturing polyacrylamide gel electrophoresis (ND-PAGE) was developed. The gel is incubated with a reaction mixture containing L-phenyl-alanine, alpha-keto-gamma-methiolbutyrate (alpha KMB), glutamate dehydrogenase, phenazine methosulfate (PMS) and nitroblue tetrazolium (NBT). Glutamine transaminase K catalyzes a transamination reaction between phenylalanine and alpha KMB. The resultant methionine is a substrate of glutamate dehydrogenase. The NADH formed in the oxidative deamination of methionine reacts with PMS and NBT to form a blue band on the surface of the gel coincident with glutamine transaminase K activity. Cysteine S-conjugate beta-lyase activity is detected in the gel by incubating the gel with a reaction mixture containing alpha KMB (to ensure maintenance of the enzyme in the pyridoxal 5'-phosphate form), S-(1,2-dichlorovinyl)-L-cysteine (DCVC), PMS, and NBT. The products of the lyase reaction interact with PMS and NBT to form a blue dye coincident with the lyase activity. In addition, a new assay procedure for measuring cysteine S-conjugate beta-lyase activity was devised. This procedure couples pyruvate formation from DCVC to the alanine dehydrogenase reaction. Preparations of purified rat kidney glutamine transaminase K yield a single protein band on ND-PAGE (apparent Mr approximately 95,000). This band coincides with both the cysteine S-conjugate beta-lyase and glutamine transaminase K activities. Activity staining showed that homogenates of rat kidney, liver, skeletal muscle, and heart possess a glutamine transaminase K/cysteine S-conjugate beta-lyase activity with an Rf value on ND-PAGE identical to that of purified rat kidney glutamine transaminase K.(ABSTRACT TRUNCATED AT 250 WORDS)
Customer Acquisition among Small and Informal Businesses in Urban India: Comparing Face‐to‐face and Mediated Channels (2007)

Abstract This study further explores the use of information and communication technologies (ICTs) in small and informal businesses in the developing world by focusing on the role of ICTs in customer acquisition and retention. Data is drawn from a survey of 317 sole proprietors and operators of small businesses with five or fewer employees in and around urban Hyderabad in Southern India. Respondents describe how various customers were acquired—via walk‐in, referral, family connections, landline telephone, mobile phone, internet/email, etc. Results suggest that face‐to‐face interactions dominate customer interactions, even among those with access to ICTs. Four tests explore whether telephony enables more specialized, hands‐off, numerous or distant relationships with customers; a significant relationship between landline ownership and total number of customers is found.
Asymmetry zero-drift errors in magnetic amplifiers (1955)

MAGNETIC-AMPLIFIER push-pull circuits, as used with position-indicating synchrotransmission systems, are supposed to have no output, if the input voltage is zero as a result of exact coincidence of alignment between the control-transformer rotor and the synchrogenerator rotor.
Polymerized bovine hemoglobin decreases oxygen delivery during normoxia and acute hypoxia in the rat (2008)

Hemoglobin-based oxygen carriers (HBOC) have been primarily studied for blood loss treatment. More recently infusions of HBOC in euvolemic subjects have been proposed for a wide variety of potential therapies in which increased tissue oxygenation would be beneficial. However, compared with the exchange transfusion models to study blood loss, less is known about HBOC oxygen delivery and vasoacitvity when it is infused in euvolemic subjects. We hypothesized that HBOC [polymerized bovine hemoglobin (PBvHb)] infusion creating hypervolemia would increase oxygen delivery to tissues during acute global hypoxia. Vascular oxygen content and hemodynamics were determined after euvolemic rats were infused with 3 ml of either lactated Ringer or PBvHb solution (13 g/dl, 1.3 g/kg) during acute hypoxia (FIO2 = 10%, 4 h) or normoxia (FIO2 = 21%) exposure. Our data demonstrated that compared with Ringer-infused animals, in hypoxia and normoxia, PBvHb treatment improved oxygen content but raised mean arterial pressure, lowered stroke volume, heart rate, and cardiac index, which resulted in a net reduction in blood flow and oxygen delivery to the tissues. The PBvHb vasoactive effect was similar in magnitude and direction as to the Ringer-infused animals treated with a nitric oxide synthase inhibitor nitro-l-arginine, suggesting the PBvHb effect is mediated via nitric oxide scavenging. We conclude that infusion of PBvHb is not likely to be useful in treating global hypoxia under these conditions.
Using space-time TCM with rotatedconstellations for transmission over mobilecommunications channels (1999)

Space-time trellis coded modulation is combined with a rotated signal set for transmission in mobile communication channels. Two systems are proposed and their performances simulated over slow selective fading channels.
Improvements of multiple FGS layers coding for low-delay applications in SVC (2007)

For low-delay applications in Scalable Video Coding, there are two alternative coding strategies based on AR-FGS for compressing multiple FGS layers. However, their coding efficiencies both suffer largely from the inherent drifting errors. In this paper, a more efficient multiple FGS layers coding structure is presented, which can provide higher coding performance within wide bitrate range and stronger error resilience. This is achieved by incorporating the partial-reconstructed enhancement layer references, instead of the complete-reconstructed ones, into the motion-compensated prediction loop of the FGS layers. Thereupon the prediction drift can be effectively decreased, especially for the middle bitrate points. Further, through selecting different-quality enhancement layer references generated with cycle-based reconstruction mechanism, more flexible video quality can be supported to be more suitable for varied practical application requirements.
Luminescence control in hybrid perovskites and their applications (2017)

Context and interaction in zoomable user interfaces (2000)

Zoomable User Interfaces (ZUIs) are difficult to use on large information spaces in part because they provide insufficient context. Even after a short period of navigation users no longer know where they are in the information space nor where to find the information they are looking for. We propose a temporary in-place context aid that helps users position themselves in ZUIs. This context layer is a transparent view of the context that is drawn over the users' focus of attention. A second temporary in-place aid is proposed that can be used to view already visited regions of the information space. This history layer is an overlapping transparent layer that adds a history mechanism to ZUIs. We complete these orientation aids with an additional window, a hierarchy tree, that shows users the structure of the information space and their current position within it. Context layers show users their position, history layers show them how they got there, and hierarchy trees show what information is available and where it is.
Impact of age on left ventricular geometry and diastolic function in elderly patients with treated hypertension (2017)

Age was independently correlated with LV concentric/functional changes regardless of LV hypertrophy, suggesting that ageing is independently involved in the progression of LV remodelling.

A Layered Architecture for Lifelike Robotic Motion (1999)

In this paper we present an architecture for the synthesis of realistic and emotionally expressive robotic motion. Our work borrows heavily from the computer graphics and classical animation communities which emphasize perceptual realism of motion, rather than mechanical efficiency. Principles of traditional animation, as articulated over the last century, are algorithmically embodied in our work, serving to create a sense of character and presence in a robot. Our architecture represents motion as layers of periodic function primitives. These primitives form more complex behaviors which are combined and sequenced by the Motion Compositor, a module that is parameterized by control weights determined by higher level abstractions. A signal-processing module modifies the overall synthesized motion, providing a complementary method for global control of affect 1 . Our layered motion architecture is currently being used to explore the emerging field of personal robotics. In particular, w...
A novel memory architecture for elliptic curve cryptography with parallel modular multipliers (2006)

Parallelization of operations is of utmost importance for efficient implementations of public key cryptography algorithms. Taking a clarification of parallelization methods at different abstraction levels of public key algorithms as a foundation, we propose a novel memory architecture for elliptic curve implementations with multiple modular multiplier units. This architecture is well-suited for different algorithms over GF(P) to be implemented on FPGAs. It allows the execution time to scale with the number of modular multipliers and features nearly no overhead compared to the mere runtime of the multipliers. The advantages of this distributed memory architecture is demonstrated by means of two different EC point multiplications algorithms
The Binding of Glycoconjugates to Human‐Milk <scp>d</scp>‐Galactosyltransferase (1976)

Through the use of affinity chromatography, a homogeneous preparation of human beta(1 leads to 4)-D-galactosyltransferase (the A protein of lactose synthase) was obtained. The specificity of this protein for glycoconjugates was studied in the presence and absence of human alpha-lactalbumin. A kinetic analysis of the transfer of D-galactose to N-acetyl-D-glucosamine and the beta(1 leads to 4) linked N-acetylglucosamine oligomers, suggested that the active site region of the enzyme contains more than one binding site for acceptor moleucles. Furthermore, experiments with Na-acetylglucosamine-beta(1 leads to4)-N-acetylmuramic-pentapeptide isolated from Micrococcus luteus indicated that the presence of a peptide chain does not enhance enzymic activity, as compared with the corresponding free disaccharide. Similar results were obtained using ovalbumin and the ovalbumin glycopeptide (which have similar apparent Km values for A protein) as galactose acceptors. In contrast to its ability to inhibit N-acetyllactosamine production, alpha-lactalbumin did not inhibit the transfer of D-galactose to the N-acetylglucosamine oligomers or the glycopeptides. Although alpha-lactalbumin can switch the specificity of A protein from N-acetyl-D-glucosamine to D-glucose resulting in the production of lactose, no transfer of galactose was observed to beta(1 leads to 4)-linked glycose oligomers or to a collagen glycopeptide, D-glycopyranosyl-alpha(1 leads to 2)-D-galactopyranosyloxy-beta(1 leads to 5)-lysine. IT therefore appears that alpha-lactalbumin can only modify human A protein for monosaccharide acceptors.
Robust Defect Detection System Using Double Reference Image Averaging for High Throughput SEM Inspection Tool (2006)

This paper reports a defect detection system for a high throughput SEM inspection tool. Although the system has a big advantage compared to optical tools, that is, the ability to detect smaller defects and voltage contrast defects, the cost of ownership (COO) remains high. To enhance COO, throughput enhancement is the critical issue. A larger beam current results in lower image noise and higher throughput. At the same time, the larger the beam current, the lower is the resolution. We suggest a robust defect detection system as a solution to the trade-off between resolution and throughput. The main inspection targets are the voltage contrast (VC) defects on the memory matte. The system judges defects by subtracting a detected image from a reference image, and then determining the defective portion as a larger difference than the pre-determined threshold in the subtracted image. If the noise variation for the two images is a in both cases, the noise in the subtracted image is 1.4 sigma (= radic(sigma <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> + sigma <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> )). We have developed a double reference image averaging (DRIA) system which improves the noise in the reference image by averaging repetitive patterns on the memory matte and noise variation on subtracted image is enhanced to a sigma (= radic(sigma <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> + sigma <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2 </sup> )) ideally. This enhancement is equivalent to a two times higher throughput than conventional systems. We also improved the electron beam optics and show that our system throughput is 400 Mpixels per second (pps), which is four times faster than previous systems
Resistive Switching in Mott Insulators and Correlated Systems (2015)

Resistive random access memories (ReRAM) form an emerging type of non‐volatile memories, based on an electrically driven resistive switching (RS) of an active material. This Feature Article focuses on a broad class of ReRAM where the active material is a Mott insulator or a correlated system. These materials can indeed undergo various insulator‐to‐metal transitions (IMT) in response to external perturbations such as electronic doping or temperature. These IMT explain most of resistive switching observed in correlated insulators as, for example, the Joule heating induced RS in VO 2 . The main part of this Feature Article is dedicated to a new mechanism of resistive switching recently unveiled in canonical Mott insulators such as (V 1‐ x Cr x ) 2 O 3 , NiS 2‐ x Se x and AM 4 Q 8 (A = Ga, Ge; M = V, Nb, Ta, Mo; Q = S, Se, Te). In these narrow gap Mott insulators, an electronic avalanche breakdown induces a resistive switching, first volatile above a threshold electric field of a few kV/cm and then non‐volatile at higher field. The low resistance state is related to the creation of granular conductive filaments, which, in the non‐volatile case, can be erased by means of Joule heating. ReRAM devices based on this new type of out of equilibrium Mott insulator‐to‐metal transition display promising performances.
Taylor expansion diagrams: a new representation for RTL verification (2002)

A new, compact, canonical representation for arithmetic expressions, called Taylor expansion diagram, is presented. This representation is based on a non-binary decomposition principle. It treats the expression as a continuous, differentiable function and applies Taylor series expansion recursively over its symbolic variables. The resulting Taylor expansion diagram (TED) is canonical for a fixed variable order. We present a theory of TED, and show how to obtain a reduced, normalized representation. We demonstrate that it has linear space complexity for arbitrarily complex polynomials, while time complexity to generate the representation is comparable to that of *BMD. The proposed TED representation is intended to facilitate the verification of RTL specifications and hard. ware implementations of arithmetic designs, and especially the equivalence checking of complex arithmetic expressions that arise in symbolic verification.
Pattern-sensitive Time-series Anonymization and its Application to Energy-Consumption Data (2014)

Time series anonymization is an important problem. One prominent example of time series are energy consumption records, which might reveal details of the daily routine of a household. Existing privacy approaches for time series, e.g., from the field of trajectory anonymization, assume that every single value of a time series contains sensitive information and reduce the data quality very much. In contrast, we consider time series where it is combinations of tuples that represent personal information. We propose (n, l, k)-anonymity, geared to anonymization of time-series data with minimal information loss, assuming that an adversary may learn a few data points. We propose several heuristics to obtain (n, l, k)-anonymity, and we evaluate our approach both with synthetic and real data. Our experiments confirm that it is sufficient to modify time series only moderately in order to fulfill meaningful privacy requirements.

Composite piezoelectrics: Basic research to a practical device (1988)

Abstract The adaptability of 1–3 PZT-rod/polymer-matrix piezoelectric composites commends them for the requirements of medical ultrasonic imaging transducers. We describe material fabrication techniques, material design considerations, and transducer design trade-offs involved in this application. A simple dice-and-fill fabrication technique yields material suitable for transducers with frequencies approaching 10 MHz. The piezocomposites provide high electromechanical coupling and low acoustic impedance – properties superior to those of the conventional piezoceramics and piezopolymers. Composite piezoelectric plates can be formed into complex shapes for beam focusing and steering. Moreover, arrays defined by simply patterning the electrode – not cutting the plate – exhibit no spurious modes in individual elements and low cross-talk between array elements. The resulting device performance is illustrated with a concave annular array which shows high sensitivity (8 dB insertion loss), large bandwidth (57%), compact impulse response (-20 dB ringdown of 3.3 periods, -40 dB ringdown of 6.2 periods) and good beam focusing. Such composite-piezoelectric ultrasonic transducers provide a paradigm for engineering material properties to optimize the performance of a practical device.

Selecting the right cache architecture for high performance PCS (2002)

The characteristics of asynchronous SRAMs have led SRAM vendors to provide new SRAM architectures with simpler interfaces in order to improve system performance. One of the new architectures that is becoming an industry standard for the second level cache (L2) for the Intel Pentium processor is a 32K/spl times/32 pipeline burst mode SRAM. The architecture, backed by Intel and multiple SRAM vendors, is an effort to standardize the 32K/spl times/32 burst mode SRAM and system design interface for a second level cache (L2) for the Pentium processor.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
OFDM code division multiplexing with unequal error protection and flexible data rate adaptation (2002)

An OFDM-CDM (orthogonal frequency division multiplexing code division multiplexing) system with adaptive symbol mapping is presented. This combination enables a robust transmission with flexible error protection and data rate adaptation for parallel data streams by exploiting additional diversity due to CDM. Performance results are presented for fading channels where OFDM-CDM with adaptive symbol mapping and soft interference cancellation is compared to conventional OFDM systems also taking into account channel coding with variable code rates.
A high slew-rate CMOS amplifier for analog signal processing (1990)

The performances of several types of analog VLSI circuits are limited by the setting behavior of CMOS amplifiers. An amplifier with a nonsaturated input stage which achieves a high slew-rate response is presented. The impact of this slew-rate amplifier on switched-capacitor circuits is described. Prototyping amplifier circuits were fabricated by the MOSIS service using a 2- mu m scalable CMOS technology. When biased at a DC power dissipation of 1 mW, the two-stage amplifier achieves a slew rate of 80 V/ mu s, a positive-supply rejection ratio of 73 dB, and a negative-supply rejection ratio of 57 dB and 50 kHz.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Adenovirus E1b55K/E4orf6 Complex Induces Degradation of the Bloom Helicase during Infection (2010)

The adenovirus (Ad) E1b55K and E4orf6 gene products assemble an E3 ubiquitin ligase complex that promotes degradation of cellular proteins. Among the known substrates are p53 and the Mre11-Rad50-Nbs1 (MRN) complex. Since members of the RecQ helicase family function together with MRN in genome maintenance, we investigated whether adenovirus affects RecQ proteins. We show that Bloom helicase (BLM) is degraded during adenovirus type 5 (Ad5) infection. BLM degradation is mediated by E1b55K/E4orf6 but is independent of MRN. We detected BLM localized at discrete foci around viral replication centers. These studies identify BLM as a new substrate for degradation by the adenovirus E1b55K/E4orf6 complex.
