Development of Low Dielectric Constant Ferroelectric Materials for the Ferroelectric Memory Feild Effect Transistor (1997)

In this paper we discuss ferroelectric materials suitable for a metal-ferroelectric-metal- insulator-semiconductor feild effect transistor (MFMIS FET). It is important for a ferroelectric material to have a low dielectric constant to enable the application of sufficient electric field to a ferroelectric layer. Films of Sr 2 Nb 2 O 7 and Sr 2 (Ta 1- x Nb x ) 2 O 7 were prepared by the sol-gel method on Pt/IrO 2 electrodes for an MFMIS FET. The ferroelectricities of Sr 2 (Ta 1- x Nb x ) 2 O 7 films were confirmed to be in the range of x =0.1–0.3. In the case of x =0.3, the largest remanent polarization was obtained in the hysteresis loop. The values of the remanent polarization and the coercive field are 0.5 µC/cm 2 and 44 kV/cm, respectively. The film has a low dielectric constant (ε r =53). The characteristics of Sr 2 (Ta 1- x Nb x ) 2 O 7 thin films are suitable for MFMIS FET.
Online abusive users analytics through visualization (2014)

In this demo, we present Abuse User Analytics (AuA), an analytical framework aiming to provide key information about the behavior of online social network users. AuA efficiently processes data from users' discussions, and renders information about users' activities in a easy to-understand graphical fashion with the goal of identifying deviant or abusive activities. Using animated graphics, AuA visualizes users' degree of abusiveness, measured by several key metrics, over user selected time intervals. It is therefore possible to visualize how users' activities lead to complex interaction networks, and highlight the degenerative connections among users and within certain threads.

On new roll-up possibilities for data stream warehouse (2007)

Data stream is a continuous real time ordered sequence of data. Recently, efforts have been made to create a multidimensional cube for data streams so that analytic processing is possible. However, this analysis restricts itself to standard OLAP operations. No attempt has been made to address the inherent time ordering that exists with the data of data streams. In this paper we introduce new functionalities for roll-up so that the inherent ordering of data in data streams can be exploited to enhance decision making.
Late infection following breast augmentation with textured silicone gel–filled implants (2005)

There is strong evidence that late infections can occur in patients who have undergone aesthetic breast augmentation using textured silicone gel-filled implants. Further studies are needed to determine whether similar late infection rates affect patients with aesthetic breast augmentation who receive saline-filled implants.
Major Barbara: II (1990)

From Annie Russell, ‘George Bernard Shaw at Rehearsals of Major Barbara’, a talk given at the St Ursula Club, New York, 28 April 1908. Printed in the Shaw Review, May 1976, from an ms in the Theatre Collection, New York Public Library. Annie Russell (1864–1936), Liverpool-born actress who had made her reputation in New York, played Major Barbara in the first production of the play, which opened at the Court Theatre on 28 November 1905.
Efficient Computation of Iceberg Quotient Cube by Bounding (2008)

Quotient cube is a summary structure for a data cube that preserves its semantics. The iceberg cubing problem is to compute the multidimensional group-by partitions that satisfy given aggregation constraints. As we know, there has been no algorithm that computes iceberg quotient cube for nonantimonotone aggregate functions. In this paper, we propose a new structure hyper-star-tree and an efficient algorithm, called IQ-Cubing, for iceberg quotient cubing with nonantimonotone aggregation constraints. We also employ the closedness measure to do pruning efficiently and utilize the closed mask to help the formation of equivalence classes. We conduct an investigation into the performance of our ideas and techniques.
Mechanisms underlying the increase in mycobacterial infections in cystic fibrosis patients on azithromycin (2011)

This study investigated the increased incidence of non-tuberculous mycobacterium (NTM) infections in cystic fibrosis (CF) patients on azithromycin. The authors were particularly interested in autophagia, a process whereby intracellular material is isolated into phagosomes and then destroyed by being fused with acid-rich lysosomes. It is disrupted by other macrolides and is crucial for the clearance of intracellular …
A message-passing distributed-memory parallel power flow algorithm (2003)

This paper presents a parallel direct linear solver based on a message-passing distributed-memory multiprocessor architecture such as a cluster of workstations. The results show that the new algorithm can achieve nearly linear speedup for two large-scale power system cases on a small cluster of GNU/Linux dual-processor workstations. The workstations are connected via 100 Mbit/s Ethernet, i.e., the parallel machine consists of hardware readily found in any engineering department. Based on the presented parallel direct linear solver, it is possible to parallelize totally the Newton power flow solution process. In addition, the METIS-based partitioning scheme can handle common control devices such as PV-PQ switching. Furthermore, by tuning the vertex and branch weights, the performance of the power flow solution can be optimized for the available hardware. For a workstation cluster on 100 Mbit/s Ethernet, the speedup appears to saturate beyond eight processors due to load imbalance and the aggregate growth of the partition separators. Nevertheless, the message-passing distributed-memory multiprocessor architecture can be used in other power system applications, such as state estimation and transient stability. Furthermore, an iterative linear solver could improve scalability.
An HMM-based bilingual (Mandarin-English) TTS. (2007)

We propose to build an HMM-based, Mandarin and English, bilingual TTS system. Starting with a simple baseline of two TTS systems built separately from Mandarin and English databases recorded by the same speaker, we construct a new, mixed-language TTS by designing language specific and independent questions to facilitate phone sharing across the two languages. With shared phones, the new system has a smaller footprint than the baseline system. The synthesis quality is either the same for non-mixed, Mandarin or English synthesis as the baseline or much better for mixed-language synthesis. The higher quality of mixed-language synthesis is confirmed by preference scores of 60.2 % vs 39.8%, obtained in a subjective listening test. A preliminary Mandarin synthesis experiment was also performed by using the model parameters in the leaf nodes of an English decision tree where Kullback-Leibler divergence is used to establish the nearest neighbor based mapping between leaf nodes in the decision trees of the two languages. A subjective transcription test shows a character accuracy of 93.9%. 1.
Structural analysis of cloned plasma membrane proteins by freeze-fracture electron microscopy (1998)

We have used freeze-fracture electron microscopy to examine the oligomeric structure and molecular asymmetry of integral plasma membrane proteins. Recombinant plasma membrane proteins were functionally expressed in Xenopus laevis oocytes, and the dimensions of their freeze-fracture particles were analyzed. To characterize the freeze-fracture particles, we compared the particle cross-sectional area of proteins with alpha-helical transmembrane domains (opsin, aquaporin 1, and a connexin) with their area obtained from existing maps calculated from two-dimensional crystals. We show that the cross-sectional area of the freeze-fracture particles corresponds to the area of the transmembrane domain of the protein, and that the protein cross-sectional area varies linearly with the number membrane-spanning helices. On average, each helix occupies 1.40 +/- 0.03 nm2. By using this information, we examined members from three classes of plasma membrane proteins: two ion channels, the cystic fibrosis transmembrane conductance regulator and connexin 50 hemi-channel; a water channel, the major intrinsic protein (the aquaporin 0); and a cotransporter, the Na+/glucose cotransporter. Our results suggest that the cystic fibrosis transmembrane conductance regulator is a dimer containing 25 +/- 2 transmembrane helices, connexin 50 is a hexamer containing 24 +/- 3 helices, the major intrinsic protein is a tetramer containing 24 +/- 3 helices, and the Na+/glucose cotransporter is an asymmetrical monomer containing 15 +/- 2 helices.
Packet sequencing: a layer-2 wan switching technology for per-flow ideal QoS and secure IP networking (2004)

Viewing the Internet as simply a best-effort, unreliable datagram network has recently given way to new, more-demanding service expectations, driven in part by the goal of multiple services delivered via a single converged IP infrastructure. However, the associated goals of an ultimate quality-of-service (QoS) that support real-time and mission-critical applications, along with utmost security and reliability, remain elusive. This paper describes a fundamental technological advance that not only attains ideal QoS with unique security and reliability capabilities but also supports full interworking with traditional IP networks, inasmuch as it does not require modification (e.g., labeling) or higher-layer/proprietary interpretation of IP packets. We describe an advanced wide-area network composed of traditional end-points, dual-mode switch/routers, and sequencing agents that provide per-flow admission and scheduling of packets on a link-by-link basis from source to destination. The network is fully scalable and can readily provide reachability across multiple domains that span the globe. Sequencing agents assure an individual, time-deterministic path for every critical application-i.e., those that require minimal transport delay (i.e., no packet queueing), no jitter and no packet loss. Moreover, since sequencing is accomplished on a per-flow basis and invokes a temporal paradigm for packet switching, we show that applications are completely immune to extraneous network influences, notably network congestion or Denial-of-Service attacks. As discussed in this paper, commercial-off-the-shelf (COTS) equipment realization has demonstrated these attributes for both customary realtime flows (examples of which include voice- and video-over-IP) and sequenced TCP flows. The latter is especially significant, in that it makes possible for the first time a system for fully managed and guaranteed throughput of TCP data while maximizing goodput, a significant advance for reliable, deterministic, secure data transmission and networked storage. This paper further makes clear that traditional end-points (e.g., videoconferencing units and IP phones) can readily operate in packet-sequenced networks. Moreover, we note that the sequencing protocol permits per-flow reuse of preallocated-but unused-throughput. Consequently, nonsequenced packets (e.g., best-effort, asynchronous data) are "backfilled" and amenable to conventional routing in either sequenced networks or interconnected, conventional IP networks, thereby providing facile interworking with the large embedded base of legacy IP equipment.
Active domains of human papillomavirus type 11 E1 protein for origin replication. (1998)

Viral proteins E1 and E2 are essential for transient human papillomavirus (HPV) DNA replication. E1 is a multifunctional protein which can bind DNA and complex with E2, has ATPase and helicase activities, and interacts with DNA polymerase alpha-primase. E2 is a transactivator-repressor protein, playing an important role in replication and transcriptional regulation. A series of deletion mutants of HPV-11 E1 were constructed and tested in functional assays to define those domains of HPV-11 E1 which are important for binding to the origin DNA and E2. The domain of HPV-11 E1 involved in binding to the origin was located between aa 186 and 649, and that for binding to E2 was between aa 346 and 649. Since E1 binds to the origin more efficiently in the presence of E2, we also mapped the DNA binding domain of E1 in the presence of E2, and found that when binding was enhanced, the region of E1 involved in binding was similar to that observed with E1 alone. The same deletion mutation constructs of E1 were subcloned into an expression vector for use in transient replication assays to study the effect of the deletions on the replication of the origin DNA in vivo and the data suggest that the C-terminal domain contains important functions for replication.
Continuously-tunable single-frequency semiconductor lasers (1987)

The design of "ideal" tunable laser sources that are capable of being continuously tuned over the entire gain bandwidth with maximum mode suppression are considered. It is shown that certain extended-cavity three-section configurations satisfy the necessary conditions for such electronic tunability, but that phase shifters with advanced capabilities are necessary. It is also shown that it is not possible to achieve this goal in a two-section configuration, although continuous tuning up to about one longitudinal mode spacing should be possible with some compromise in spurious mode suppression.

A novel IP with MPLS over WDM-based broad-band wavelength switched IP network (2001)

This paper presents a new technology for constructing IP over photonic systems. An IP with multiprotocol label switching (MPLS) over wavelength division multiplexing (WDM)-based broad-band IP network architecture and protocol is proposed and analyzed in this paper, which supports variable-length IP-like optical packet label switching and optical virtual path routing. This system tries to merge into one layer the functionalities of the wavelength switching, SONET mux/demux, and IP routing, and is sometimes known as the concept of optical MPLS. The label banding, forwarding/switching process, and node architecture of the proposed network are discussed and studied. A unique as well as important function of a lambda/label edge router (LER) is a flow assembly device that can encompass MPLS' forward equivalence classes, label stacking, and label switching path aggregation function. At the same time, a particular function of the core label switching router is wavelength merging. A fiber delay line is used to delay the data stream in order to process the label information and resolve contention. Transmission bit error rate measurements of the baseband data stream and back-to-back is also demonstrated to show its feasibility.
Beyond the Attack Surface (2016)

When reasoning about software security, researchers and practitioners use the phrase ``attack surface'' as a metaphor for risk. Enumerate and minimize the ways attackers can break in then risk is reduced and the system is better protected, the metaphor says. But software systems are much more complicated than their surfaces. We propose function- and file-level attack surface metrics---proximity and risky walk---that enable fine-grained risk assessment. Our risky walk metric is highly configurable: we use PageRank on a probability-weighted call graph to simulate attacker behavior of finding or exploiting a vulnerability. We provide evidence-based guidance for deploying these metrics, including an extensive parameter tuning study. We conducted an empirical study on two large open source projects, FFmpeg and Wireshark, to investigate the potential correlation between our metrics and historical post-release vulnerabilities. We found our metrics to be statistically significantly associated with vulnerable functions/files with a small-to-large Cohen's d effect size. Our prediction model achieved an increase of 36% (in FFmpeg) and 27% (in Wireshark) in the average value of F{2}-measure over a base model built with SLOC and coupling metrics. Our prediction model outperformed comparable models from prior literature with notable improvements: 58% reduction in false negative rate, 81% reduction in false positive rate, and 548% increase in F{2}-measure. These metrics advance vulnerability prevention by [(a)] being flexible in terms of granularity, performing better than vulnerability prediction literature, and being tunable so that practitioners can tailor the metrics to their products and better assess security risk.
Power minimization strategy in MOS transistors using quasi-floating-gate (2003)

The current trend for today's computing products has been mobile technology solutions. These products include cellular phones, laptop computers, personal digital assistants (PDA), and more. In order to provide reliable computing and communication devices such as the ones listed above, the components necessary to construct these devices must be designed for a low-power environment. This implies that the supply voltage and supply currents must be lowered to realize longer battery life and thus consumer approval. A novel design technique for closed-loop amplifier circuits, suited to very low supply voltages, is proposed. This paper will show a method known as Quasi-Floating-Gate (QFG) MOS transistors that allows the operation of amplifier circuits at very low supply voltages. QFG transistors are particularly suitable to applications involving closed-loop amplifier circuits based on multiple-input capacitive dividers. QFG transistors have noticeable gains over current floating-gate MOS transistors in that floating-gate MOS structures are subject to Gain-Bandwidth product degradation and large initial floating gate charge. The applications presented in this paper are vital for the mobile system environment. Included herein are a programmable gain inverting amplifier, a sample and hold circuit, and a digital-to-analog converter, which are all composed of QFG input pair transistors. Each circuit will be discussed in detail as well as the building blocks for these circuits, including the QFG transistor.
Systematic review of the validity and reliability of consumer-wearable activity trackers (2015)

This systematic review indicated higher validity of steps, few studies on distance and physical activity, and lower validity for energy expenditure and sleep. The evidence reviewed indicated high interdevice reliability for steps, distance, energy expenditure, and sleep for certain Fitbit models. As new activity trackers and features are introduced to the market, documentation of the measurement properties can guide their use in research settings.
Measurement of total homocysteine in plasma and blood spots using liquid chromatography-tandem mass spectrometry: comparison with the plasma Abbott IMx method (2003)

We have developed a precise and accurate LC-MS/MS method for measuring plasma tHcy concentrations, which uses a small volume of plasma and is suitable for routine use. A satisfactory LC-MS/MS method for the measurement of tHcy in dried blood spots was also developed; this method might be useful in routine screening for raised plasma concentrations of tHcy.
Comparative Study of Two Low CO2 Emission Power Generation System Options With Natural Gas Reforming (2008)

Two power plant schemes that reduce CO2 emission and employ natural gas reforming were analyzed and discussed. The first one integrates natural gas reforming technology for efficiency improvement with an oxy-fuel combined power system (OXYF-REF), with water as the main work fluid. The reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel with oxygen as the oxidizer. The turbine working fluid can expand down to a vacuum, producing a high-pressure ratio and thus more net work. The second system integrates natural gas reforming in a precombustion decarbonization scheme using chemical absorption technology for the CO2 removal (PCD-REF). The gas turbine is the conventional air-based one with compressor intercooling. Supplementary combustion is employed to elevate the turbine exhaust temperature and thus achieve a much higher methane conversion rate (96.9%). Both systems involve internal heat recuperation from gas turbine exhausts, and particular attention has been paid to the integration of the heat recovery chain to reduce the related exergy destruction. The systems are simulated and their thermal efficiency, overall and component exergy losses, and CO2 removal capacity are compared. The OXYF-REF system has a higher energy efficiency, of 51.4%, and higher CO2 removal, but the product CO2 has lower purity, of 84%. The PCD-REF system has a thermal efficiency of 46%, the captured CO2 is 99% pure, and the CO2 specific emission is 58.5g∕kWh.
