Ovarian Clear Cell Carcinoma (1989)

The clinical aspects and pathologic findings in 44 cases of pure clear cell carcinoma of the ovary are presented. The patients ranged in age from 28 to 78 years (mean, 50.6 years); 54% were nulliparous. Thirty-three percent of the patients had endometriosis in the involved ovary, and an additional 25% had endometriosis only in sites distant from the tumor. Microscopically, three architectural patterns (papillary, tubulocystic, and solid) and four cell types (clear, hobnail, eosinophilic, and flattened) were seen. A predominant tubulocystic architectural pattern was a good prognostic factor (p less than 0.01); however, no significant difference in survival by cell type was found. Grading of the tumors by conventional architectural and cytologic criteria had no predictive value for survival. Stage at presentation was the most important prognostic factor (p less than 0.001), with a 5-year overall survival of 34% and stage I survival of 55%. The poor stage I survival reflects the 15 patients (34%) in the study with stage Iaii lesions. In the 25 patients who developed recurrence, both distant organ involvement (40%) and lymph node involvement (40%) were frequent. Ovarian clear cell carcinoma has unusual pathologic and clinical features, and it represents a distinct histologic type of ovarian carcinoma.
Multiscale Entanglement Renormalization Ansatz in Two Dimensions: Quantum Ising Model (2008)

We propose a symmetric version of the multiscale entanglement renormalization ansatz in two spatial dimensions (2D) and use this ansatz to find an unknown ground state of a 2D quantum system. Results in the simple 2D quantum Ising model on the 8x8 square lattice are found to be very accurate even with the smallest nontrivial truncation parameter.

Prognostic enhancements to gas turbine diagnostic systems (2004)

Abstract : The development of machinery health monitoring technologies has taken center stage within the DoD community in recent years. Existing health monitoring systems, such as the Integrated Condition Assessment System (ICAS) for NAVSEA, enable the diagnosis of mission critical problems using fault detection and diagnostic technologies. These technologies, however, have not specifically focused on the automated prediction of future condition (prognostics) of a machine based on the current diagnostic state of the machinery and its available operating and failure history data. Current efforts are focused on developing a generic architecture for the development of prognostic systems that will enable plug and play capabilities within existing systems. The designs utilize Open System Architecture (OSA) guidelines, such as OSA-CBM (Condition Based Maintenance), to provide these capabilities and enhance reusability of the software modules. One such implementation, which determines the optimal water wash interval to mitigate gas turbine compressor performance degradation due to salt deposit ingestion, is the focus of this paper. The module utilizes advanced probabilistic modeling and analysis technologies to forecast the future performance characteristics of the compressor and yield the optimal Time To Wash (TTW) from a cost/benefit standpoint. This paper describes the developed approach and architecture for developing prognostics using the gas turbine module.
Super-hydrophobic/super-hydrophilic patterning of gold surfaces by photocatalytic lithography (2005)

Super-hydrophobic and super-hydrophilic gold surfaces were prepared by modifying microstructured gold surfaces with thiols. The perfluorodecanethiol (PFDT)-modified rough gold surface was converted from super-hydrophobic (water contact angle = 150–160°) to super-hydrophilic (0–10°) by photocatalytic remote oxidation using a TiO2 film. During the remote oxidation, oxygen-containing groups were introduced to the thiol, and finally, even sulfur atoms were removed. Super-hydrophobic/super-hydrophilic patterns were also obtained by photocatalytic lithography, by using a TiO2-coated photomask. On the basis of this technique, enzymes and algal cells were patterned on the gold surfaces to fabricate biochips.

Influences of Electron Beam Irradiation on Impact Value for Silica Glass (2006)

Influences of electron beam (EB) irradiation on the impact value for silica glass were studied by using a standard Charpy impact test. EB irradiation below 0.216 MGy, which was one of short-time treatments of dry process at low temperature, increased impact values of the glass. As the EB irradiation generated dangling bonds of the E′ center at the silicon-oxygen atomic pairs in the silica glass, partial relaxation occurred at points of residual strain near dangling bonds in the network structure mainly constructed with silicon-oxygen pairs. If the inter-atomic distance of the silicon-oxygen pairs became to be optimum potential curves of the silica glass, the relaxation should increase the bonding energy of the network structure. Evidently, the increased impact value was mainly due to an increase in the bonding energy for the silicon-oxygen atomic pairs in the atomic network structure, as well as a relaxation of the network structure.
A resistor/transconductor network for linear fitting (2000)

We present a continuous time analog VLSI CMOS circuit consisting of resistors and transconductors for computing the best-fit line to a set of data points. The circuit can implement standard least-squares linear fitting, as well as a form of linear fitting that is more robust to outliers. We analyze the static and transient response of the chip, and present design criteria given desired constraints on speed and accuracy. Finally, we describe the transistor level design and measurement results from a 50-input prototype fabricated using a 1.2 /spl mu/m n-well process.
Combining Evidence for Improved Speech Retrieval (2007)

The goal of my dissertation research is to investigate the combination of new evidence sources for improving information retrieval on speech collections. The utility of these evidence sources is expected to vary depending on how well they are matched to a collection’s domain. I outline several new evidence sources for speech retrieval, situate them in the context of this domain dependency, and detail several methods for their combination with speech recognition output. Secondly, I highlight completed and proposed work for the production of this evidence.
The occurrence of long chain polyprenols in leaves of plants of <i>Rosaceae</i> family and their isolation by time-extended liquid chromatography (1992)

The long chain polyprenols composed of 30 and more isoprene units from leaves of plants belonging to the genera Potentilla and Rosa have been described. They occur in the form of fatty acid esters. The composition of polyprenol mixture was species dependent and its content reached ca. 0.5% wet weight. Large scale preparation of individual polyprenols from a natural polyprenol mixture was performed using time-extended liquid chromatography on the hydrophobic gel Lipidex-5000.
The crucial effect of early-stage gelation on the mechanical properties of cement hydrates (2016)

Gelation and densification of calcium-silicate-hydrate take place during cement hydration. Both processes are crucial for the development of cement strength, and for the long-term evolution of concrete structures. However, the physicochemical environment evolves during cement formation, making it difficult to disentangle what factors are crucial for the mechanical properties. Here we use Monte Carlo and Molecular Dynamics simulations to study a coarse-grained model of cement formation, and investigate the equilibrium and arrested states. We can correlate the various structures with the time evolution of the interactions between the nano-hydrates during the preparation of cement. The novel emerging picture is that the changes of the physicochemical environment, which dictate the evolution of the effective interactions, specifically favour the early gel formation and its continuous densification. Our observations help us understand how cement attains its unique strength and may help in the rational design of the properties of cement and related materials.
Research of trust model based on fuzzy theory in mobile <i>ad hoc</i> networks (2013)

The performance of ad hoc networks depends on the cooperative and trust nature of the distributed nodes. To enhance security in ad hoc networks, it is important to evaluate the trustworthiness of other nodes without central authorities. An information‐theoretic framework is presented, to quantitatively measure trust and build a novel trust model (FAPtrust) with multiple trust decision factors. These decision factors are incorporated to reflect trust relationship's complexity and uncertainty in various angles. The weight of these factors is set up using fuzzy analytic hierarchy process theory based on entropy weight method, which makes the model has a better rationality. Moreover, the fuzzy logic rules prediction mechanism is adopted to update a node's trust for future decision‐making. As an application of this model, a novel reactive trust‐based multicast routing protocol is proposed. This new trusted protocol provides a flexible and feasible approach in routing decision‐making, taking into account both the trust constraint and the malicious node detection in multi‐agent systems. Comprehensive experiments have been conducted to evaluate the efficiency of trust model and multicast trust enhancement in the improvement of network interaction quality, trust dynamic adaptability, malicious node identification, attack resistance and enhancements of system's security.
Two simple stopping criteria for iterative decoding (2002)

This paper presents two simple and effective criteria for stopping the iteration process in iterative decoding with a negligible degradation of the error performance. Both criteria are devised based on the cross entropy concept and are as efficient but simpler than the cross-entropy criterion.
Optimizations for Compiled Simulation Using Instruction Type Information (2004)

The design of new architectures can be simplified with the use of retargetable instruction set simulation tools, which can validate the design decisions in the design exploration cycle with high flexibility and reduced cost. The growing system complexity makes the traditional approach inefficient for today's architectures. Compiled simulation techniques make use of a priori knowledge to accelerate the simulation, with the highest efficiency achieved by employing static scheduling techniques. This paper presents our approach to the static scheduling compiled simulation technique that is 90% faster than the best published performance results. It also introduces two novel optimization techniques based on instruction type information that further increase the simulation speed by more than 100%. The so-called fast static compiled simulation (FSCS) technique applicability will be demonstrated by the use of the SPARC and MIPS architectures.
Hippocampal BDNF mediates the efficacy of exercise on synaptic plasticity and cognition (2004)

We found that a short exercise period enhanced cognitive function on the Morris water maze (MWM), such that exercised animals were significantly better than sedentary controls at learning and recalling the location of the platform. The finding that exercise increased brain-derived neurotrophic factor (BDNF), a molecule important for synaptic plasticity and learning and memory, impelled us to examine whether a BDNF-mediated mechanism subserves the capacity of exercise to improve hippocampal-dependent learning. A specific immunoadhesin chimera (TrkB-IgG), that mimics the BDNF receptor, TrkB, to selectively bind BDNF molecules, was used to block BDNF in the hippocampus during a 1-week voluntary exercise period. After this, a 2-trial-per-day MWM was performed for 5 consecutive days, succeeded by a probe trial 2 days later. By inhibiting BDNF action we blocked the benefit of exercise on cognitive function, such that the learning and recall abilities of exercising animals receiving the BDNF blocker were reduced to sedentary control levels. Inhibiting BDNF action also blocked the effect of exercise on downstream systems regulated by BDNF and important for synaptic plasticity, cAMP response-element-binding protein (CREB) and synapsin I. Specific to exercise, we found an association between CREB and BDNF expression and cognitive function, such that animals who were the fastest learners and had the best recall showed the highest expression of BDNF and associated CREB mRNA levels. These findings suggest a functional role for CREB under the control of BDNF in mediating the exercise-induced enhancement in learning and memory. Our results indicate that synapsin I might also contribute to this BDNF-mediated mechanism.
Novel linearization circuit for BiCMOS transconductors used in high frequency OTA-C filters (2002)

A novel linearization circuit for a tunable BiCMOS transconductor based on the emitter degeneration of bipolar devices is analyzed. The transconductor is suitable for high-frequency continuous-time filter implementations because of the large value of the gm/I ratio and its ease of tunability. An integrator cell with a unity gain bandwidth of up to 80 MHz can be realized with a capacitive load as large as 3 pF and a power consumption of about 3.5 mW. An extended tuning range can be achieved through the proposed linearization circuit that reduces the total harmonic distortion (THD) in the lower part of the tuning range. Simulation program with IC emphasis (SPICE) simulation results are presented, comparing the classical solution with respect to the linearized one; the input stage shows an output current THD less than 1% for an input differential signal of up to 500m V/sub pp/ over an almost 10:1 tuning range.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Mapping the electronic properties of individual graphene grain boundaries (2012)

Grain boundaries, the characteristic topological defects of chemical vapor deposition grown graphene samples, are expected to substantially alter the electronic properties of the unperturbed graphene lattice. However, there is very little experimental insight into the underlying mechanisms. Here, we systematically map the electronic properties of individual graphene grain boundaries by scanning tunneling microscopy and spatially resolved tunneling spectroscopy measurements. The tunneling spectroscopy data reveal that the conductivity inside the boundaries is markedly suppressed for both electron and hole-type charge carriers. Furthermore, graphene grain boundaries can give rise to n-type inversion channels within the p-doped graphene sheets, forming p-n junctions with sharp interfaces on the nanometer scale. These properties persist for grain boundaries of various configurations and are robust against structural disorder.
Computational intelligence-based testing for noise and robustness analysis (2005)

Interconnect and power supply noise (PSN) is becoming more severe as technology scales, and can cause signal distortion and increase gate delay. This can further result in improper circuit operation. This paper describes a novel computational intelligence with ultra-short worst case test flow concept to detect a hang-up in a pseudo-SRAM test chip with asynchronous operation and hidden refresh, Package parasitics are found to be the cause of the failure, and debugging is performed by modification of the power network. This method allows finding worst case tests and identifying design weaknesses efficiently.
Spectral estimation of speech by mel‐generalized cepstral analysis (1993)

Abstract This paper proposes a spectral estimation method of speech based on mel‐generalized cepstral representation. The spectral estimation based on generalized cepstral representation is a method that unifies the cepstral method and the linear prediction method. By this method, the spectral model can be varied continuously from the all‐pole model to the exponential model. This paper also discusses the following: the method of spectral estimation, where the mel‐generalized cepstrum is used instead of the generalized cepstrum; the uniqueness of the solution for the minimization problem; the solution method; and the convergence of the solution. The proposed method has the same features as those of the method based on the generalized cepstrum where the spectral model can be varied continuously and the stability of the obtained transfer function is guaranteed. Another feature is that characteristics similar to the human auditory sensation, i.e., the high resolution in the low‐frequency range and the coarse resolution in the high‐frequency range, are obtained since the mel‐generalized cepstrum is used as the parameter, which is the generalized cepstrum defined on the mel‐frequency axis. Finally, the features and the effectiveness of the proposed method is demonstrated by analysis examples of the synthesized signals and natural speech.
How can crowdsourcing help in crisis situations? Missing kids case study (2016)

Crowdsourcing consists of tools and methods that harness the potential of the crowd (intelligence and sense of creativity). It is increasingly used in different fields especially in some extreme emergency cases that require broad collaboration of all citizens. This collaboration will be unsuccessful or at least a heavy work without the ubiquity of new information technologies and the emergence of smartphones and mobile devices. They become more and more powerful mainly with the ‘anytime and anywhere’ Internet access. The contribution of this paper is twofold: we introduce a framework that can be widely used by government organizations to stimulate the crowd participation in a missing child case and we also reveal the importance of crowdsourcing in an e-government context to cope with society's changes.
THE DEVELOPMENT OF ENDOMYCORRHIZAL ROOT SYSTEMS: I. SPREAD OF INFECTION AND GROWTH‐PROMOTING EFFECTS WITH FOUR SPECIES OF VESICULAR‐ARBUSCULAR ENDOPHYTE (1977)

SUMMARY Four vesicular‐arbuscular endophytes were inoculated into onions cultured in soil in a growth chamber. Dry weight, root length, infected root length, phosphorus content and quantity of external mycelium were measured at intervals. Three endophytes produced similar hyphal inflows, growth increments and external mycelium. One endophyte produced no growth increase in the host, and had little external mycelium and slow increase in percentage infection.
