G4-FET modeling for circuit simulation by adaptive neuro-fuzzy training systems (2012)

G4-FET has attracted attention as an emerging device for the future generations of semiconductor industry. This paper is intended to propose a model representing the characteristics of G4-FET device in order to perform circuit simulations. The modeling approach is established upon the neuro-fuzzy technique whose main strength is that they are universal approximators with the ability to solicit interpretable IF-THEN rules. The accuracy of the proposed model is verified by HSPICE circuit simulations.
Performance of the Phase Doppler Particle Analyzer icing cloud droplet sizing probe in the NASA Lewis Icing Research Tunnel (1992)

The design, development, and testing of an icing cloud droplet sizing probe based upon the Phase Doppler Particle Analyzer (PDPA) are discussed. This probe is an in-situ laser interferometry based single particle measuring device capable of determining size distributions. The probe is designed for use in harsh environments such as icing tunnels and natural icing clouds. From the measured size distribution, Median Volume Diameter (MVD) and Liquid Water Content (LWC) may be determined. Both the theory of measurement and the mechanical aspects of the probe design and development are discussed. The MVD results from the probe are compared to an existing calibration based upon different instruments in a series of tests in the NASA Lewis Icing Research Tunnel. Agreement between the PDPA probe and the existing calibration is close for MVDs between 15 to 30 microns, but the PDPA results are considerably smaller for MVDs under 15 microns.
Complications of haemophilia in babies (first two years of life): a report from the Centers for Disease Control and Prevention Universal Data Collection System (2016)

Bleeding events in haemophilic babies ≤2 years were common; no detectable difference in the rates of ICH by the mode of delivery was noted. Neonatal factor exposure did not affect the inhibitor rates. Minor head trauma, soft tissue and oropharyngeal bleeding were the leading indications for treatment.
Sobre la posición monetaria neta (1969)

Este artículo presenta tres modelos macroeconómicos. El primero está basado sobre el modelo usado por el profesor Olivera en su artículo "La posición monetaria neta", publicado en esta revista, en el primer número de 1968. En el segundo modelo, los bonos emitidos por el gobierno no son medidos por su valor nominal, como ocurre en el primer modelo, sino por el valor actual de los cupones. En el tercer modelo, se ha supuesto que una parte de la oferta de bonos se agrega a la oferta del mercado del dinero. La efectividad de las políticas monetaria y fiscal es comparada en los tres modelos. También se discute el significado que debe darse a la diferente fuerza de ambas políticas.
Properties of the gamma subunit of phosphorylase kinase. (1987)

Enzymatic properties of the isolated, active gamma subunit of phosphorylase kinase were characterized. Kinetic parameters indicated that the gamma subunit binds the substrates MgATP and phosphorylase b as well as the holoenzyme with a Km (MgATP) of 98 microM and a Km (phosphorylase b) of 80 microM at pH 8.2, but maximal velocities are significantly lower than the holoenzyme's. Unlike the gamma-calmodulin complex, the gamma subunit activity is dependent on pH in the range of pH 6.2-9.0, with a ratio of activity at pH 6.8 to activity at pH 8.2 of 0.5-0.6. Calmodulin activates the gamma subunit more at low pH than at high pH. ADP inhibits the gamma subunit in a competitive manner with a Ki of 60 microM. Free Mg2+ stimulates gamma subunit activity 3.5-fold at both pH 6.8 and 8.2. MnATP is equivalent to MgATP as a substrate for the enzyme, but free Mn2+ inhibits gamma subunit activity. Several protein substrates of holophosphorylase kinase were found also to be phosphorylated by the gamma subunit. These included kappa-casein, myelin basic protein, the troponin complex, and troponin T alone. In the troponin complex, the proportion of 32P incorporated by the gamma subunit into troponin I compared with troponin T was not Ca2+ dependent, but with the holoenzyme, this proportion was changed greatly by Ca2+ concentration.

Improvement in Structural and Functional Echocardiographic Parameters During Chronic Heart Failure Therapy Guided by Natriuretic Peptides: Mechanistic Insights from the ProBNP Outpatient Tailored Chronic Heart Failure (PROTECT) Study (2012)

NT-proBNP concentrations may serve as a non-invasive indicator of the state of cardiac structure and function in HF due to LVSD. Multiple, prognostically meaningful echocardiographic variables improved more significantly in patients treated with NT-proBNP-guided care vs. SOC.
Efficient resolution of replicated poxvirus telomeres to native hairpin structures requires two inverted symmetrical copies of a core target DNA sequence (1987)

The terminal hairpin sequences of the linear double-stranded DNA genome of the leporipoxvirus Shope fibroma virus (SFV) has been cloned in Saccharomyces cerevisiae and in recombination-deficient Escherichia coli as a palindromic insert within circular plasmid vectors. This sequence configuration is equivalent to the inverted repeat structure detected as a telomeric replicative intermediate during poxvirus replication in vivo. Previously, it has been shown that when circular plasmids containing this palindromic insert were transfected into SFV-infected cells, efficient replication and resolution generated linear minichromosomes with bona fide viral hairpin termini (A. M. DeLange, M. Reddy, D. Scraba, C. Upton, and G. McFadden, J. Virol. 59:249-259, 1986). To localize the minimal target DNA sequence required for efficient resolution, a series of staggered unidirectional deletions were constructed at both ends of the inverted repeat. Analyses of the resolution efficiencies of the various clones indicate that up to 240 base pairs (bp) centered at the symmetry axis were required for maximal resolution to minichromosomes. To investigate the role of the AT-rich central axis sequences, which in SFV include 8 nonpalindromic bp, a unique AflII site at the symmetry axis was exploited. Bidirectional deletions extending from this AflII site and insertions of synthetic oligonucleotides into one of the deletion derivatives were constructed and tested in vivo. The efficiency with which these plasmids resolved to linear minichromosomes with hairpin termini has enabled us to define the minimal target DNA sequence as two inverted copies of an identical DNA sequence between 58 and 76 bp in length. The nonpalindromic nucleotides, which, after resolution, constitute the extrahelical residues characteristic of native poxviral telomeres, were not required for resolution. The close resemblance of the SFV core target sequence to the analogous region from the orthopoxvirus vaccinia virus is consistent with a conserved mechanism for poxviral telomere resolution.
<i>In vitro</i> metabolism of a novel phosphodiesterase‐5 inhibitor DA‐8159 in rat liver preparations using liquid chromatography/electrospray mass spectrometry (2002)

The in vitro metabolism of a new erectogenic, DA-8159, has been studied by LC with UV detection and on-line LC-electrospray mass spectrometry using rat hepatic microsomal incubation and rat liver perfusion. Both rat liver microsomal incubation of DA-8159 in the presence of NADPH and single-pass liver perfusion of DA-8159 resulted in the formation of three metabolites (M1-3). M1 was tentatively identified as hydroxy-DA-8159. M2 and M3 were identified as N-demethyl-DA-8159 and 5-(2-propyloxy-5-aminosulphonylphenyl)-1-methyl-3-propyl-1,6-dihydro-7H-pyrazolo(4,3-d)pyrimidin-7-one (DA-8164), respectively, on the basis of LC-MS/MS analysis with authentic standards. Rat CYP2D1 was a major isozyme for the formation of hydroxy-DA-8159 and N-demethyl-DA-8159. CYP2C12 and CYP1A1 catalysed the oxidation of DA-8159 to DA-8164.
Regulation of PDGF and PDGF receptor in cultured dermal papilla cells and follicular keratinocytes of the human hair follicle (2003)

Platelet-derived growth factor (PDGF) is a potent mitogenic factor for many cell types and has been shown to be important in follicular development and vasculogenesis. In this study, we examined the expression pattern of both PDGF factors and their corresponding receptors in mesenchyme-derived dermal papilla cells (DPCs) and epithelial follicular keratinocytes (FKs). Both types of PDGF receptors are expressed in FKs, whereas DPCs only express PDGF receptor beta on the protein level, a finding also seen in whole organ cultures. By examining the expression of PDGF ligands, we were able to show that cultured FKs synthesize both PDGF-A and PDGF-B, whereas, DPCs only express PDGF-A. As immunomodulatory cytokines were shown to affect hair growth, we investigated the effects of IL-1beta, IL-4, TNF-alpha, TGF-beta and IFN-gamma on the expression levels of PDGF factors in cultured DPCs and FKs. Interestingly, we could show a significant down-regulatory effect by catagen-inducing cytokines like IL-1beta or IFN-gamma, suggesting a possible involvement of PDGF signaling in the induction of catagen. The question concerning the latter hypothesis remains to be elucidated in further studies on whole organ cultures.

Survey on Ranking Functions in Keyword Search over Graph-Structured Data (2020)

Keyword search is known as an attractive alternative for structured query languages in querying over graph-structured data. A keyword query is expressed by a set of keywords and respond by a set of connected structures from the database, which totally or partially cover the queried keywords. These results show how the queried keywords are related in the database. Since there may be numerous results to a given query, a ranking function is essential to present top-k more relevant results to the user. The effectiveness of this function directly affected the effectiveness of the keyword search system. In this paper, we survey the proposed ranking functions in the context of keyword search. First, the proposed models for the results of a keyword query are discussed and a categorization of them is presented. Next, the effective factors in determining the relevance of results are examined. Then, various ranking functions for ordering the results of a query are described and categorized based on their main view in determining the semantic of the results. Finally, we present an analysis of these classes and discuss the evolution of new research strategies to resolve the issues associated with the ranking of results in the keyword search domain.
Combination of KIR 2DL2 and HLA‐C1 (Asn<sup>80</sup>) confers susceptibility to type 1 diabetes in Latvians (2008)

Killer immunoglobulin-like receptors (KIRs) are known to modulate natural killer (NK) and NK T-cell function by interacting with human leucocyte antigen (HLA) class I ligands on target cells. The aim of our study was to investigate the influence of KIR2D genes with their HLA-C ligands in susceptibility to type 1 diabetes. A total of 98 type 1 diabetes patients and 70 healthy subjects from Latvia were typed for KIR genes and HLA-C ligands using polymerase chain reaction-based genotyping. The HLA C1+/C2+ combination was positively, and C1-/C2+ combination was negatively, associated with type 1 diabetes. Stratification analysis of KIR/HLA-C ligand combinations showed 2DL2+/C1+, 2DL3+/C1+, and 2DS2+ /C1+ to be positively, and 2DL2-/C1- and 2DS2-/ C1- to be negatively, associated. The presence of 2DL2-HLA-C1 in the absence of 2DS1, 2DS2 confers maximum susceptibility. Absence of 2DL2 and HLA-C1 along with absence of 2DS1 and 2DS2 confer maximum protection. A hypothetical model of KIR/ligand combinations on immune responses and type 1 diabetes susceptibility is proposed. Our results suggest that a combination KIR2DL2- HLA-C1 plays a critical role in susceptibility or protection in Latvians against type 1 diabetes.
A Depolarization Criterion in Mueller Matrices (1985)

Abstract A necessary and sufficient scalar condition for a Mueller matrix M to describe a non-depolarizing optical system is obtained. By computing only one scalar parameter, it can be determined whether a given Mueller matrix M describes a non-depolarizing, or a depolarizing optical system. The following theorem is stated: a necessary and sufficient condition for a given Mueller matrix M to describe a non-depolarizing optical system is Tr(M T M) = 4m 2 00.
The Physics of Steam Injection in Fractured Carbonate Reservoirs: Engineering Development Options that Minimize Risk (2006)

Abstract Naturally fractured carbonate reservoirs hold well over 100 billion barrels of heavy oil worldwide. Thermally Assisted Gas Oil Gravity Drainage (TAGOGD) is a new and novel thermal EOR technique, which has applicability in selected reservoirs. In conventional isothermal GOGD, vertical fractures cause the gas-oil contact in the fracture system to advance ahead of the gas-oil contact within the matrix blocks, causing the oil in these blocks to become mobile. The addition of heat in the fractures generates additional hydrocarbon gas cap, lowers the viscosity of the oil, and accelerates conventional GOGD, as seen in the 220 cp heavy-oil Qarn Alam field in Oman. Pilot results in the Qarn Alam field support the commerciality of this process, and a first-of-it's-kind steam injection project is being implemented. The economic success of the Qarn Alam project depends on the ability to credibly predict steam requirements and oil production. Two key oil production mechanisms are heat transport through the fractures and into the matrix, and subsequent gas cap generation due to thermal volatilization of the oil. The process mechanisms involved in TAGOGD were validated through laboratory experiments, while the field forecast model results were validated by history matching pilot performance data. A fully integrated workflow of fracture characterization, integrated reservoir physics, and static and dynamic modeling has enabled uncertainties and risks involved in developing the Qarn Alam field to be managed in a scenario based design approach.
Testing and Commercialization of Byproduct Dibasic cids as Buffer Additives for Limestone Flue Gas esulfurization Systems (1983)

Pilot plant (0.1 MW) tests and utility boiler full scale demonstration (194 MW) of byproduct organic dibasic acids (DBA) as buffer additives to limestone scrubbers have shown performance improvements equivalent to those achieved by the addition of pure adipic acid. Both SO2 removal efficiency and limestone utilization increased, and no significant operating problems were observed with three of the four DBA tested. Chemical and biological evaluations of scrubber samples taken during the DBA testing indicated no detectable tOxicity or mutagenicity, and no significant environmental impact is expected as a result of DBA addition. Economic estimates indicate that substitution of DBA for pure adipic acid as a buffer additive will result in additive cost savings of 30 % or greater.
Human Dishevelled Genes Constitute a DHR-Containing Multigene Family (1997)

Three human genes encoding proteins homologous to Drosophila Dishevelled protein were cloned and characterized. Amino acid similarity between the different Dishevelled proteins is concentrated in three highly conserved regions. Two of these regions do not exhibit significant sequence similarity with other known proteins; the third is similar to the discs-large homology region, which was first found in a Drosophila Discs-large tumor suppressor protein (also known as GLGF or PDZ domain). We produced antibodies against human Dishevelled-2 and demonstrated that it is a phosphoprotein and can be detected in all cell lines and human embryonic tissues examined. Indirect immunofluorescence indicates that it is found throughout the cytoplasm. Our results indicate that the human dishevelled genes constitute a multigene family and that Dishevelled proteins are highly conserved among metazoans.

Hidden Markov Model Based Signal Characterization for Weak Light Communication (2018)

Weak illumination by light emitting diode (LED) can be realized by either peak-power transmission at a low duty cycle or low-power transmission at a regular duty cycle. In this paper, we address the signal characterization and transmission rate of visible light communication for the latter case. We first characterize the LED nonlinear effect via a state transition model based on the experimental measurements. Then, we adopt hidden Markov model (HMM) to characterize the LED transmission under weak illumination. Based on the HMM, we propose a Monte Carlo method to compute the achievable transmission rate and apply Viterbi algorithm to detect the signals. The achievable transmission rates and detection performance of the HMM-based model are evaluated by simulation results. Moreover, both numerical and experimental results show lower bit error rate of the Viterbi algorithm compared with the per symbol detection.
A dynamic platform for runtime adaptation (2009)

We present a middleware platform for assembling pervasive applications that demand fault-tolerance and adaptivity in distributed, dynamic environments. Unlike typical adaptive middleware approaches, in which sophisticated component model semantics are embedded into an existing, underlying platform (e.g., CORBA, COM, EJB), we propose a platform that imposes minimal constraints for greater flexibility. Such a tradeoff is advantageous when the platform is targeted by automatic code generators that inherently enforce correctness by construction. Applications are written as simple, single-threaded programs that assemble and monitor a set of distributed components. The approach decomposes applications into two distinct layers: (1) a distributed network of interconnected modules performing computations, and (2) constructor logic that assembles that network via a simple block-diagram construction API. The constructor logic subsequently monitors the configured system via a stream of high-level events, such as notifications of resource availability or failures, and consequently provides a convenient, centralized location for reconfiguration and debugging. The component network is optimized for performance, while the construction API is optimized for ease of assembly.
A multiple regression model for patent appraisal (2006)

Purpose Concerning the general patent trading mechanism, this paper proposes a systematic patent appraisal model to provide patent transferors and transferees a reasonable price suggestion of the target patent. Design/methodology/approach Based on the appraisal factors (including the patent transferor, patent transferee, patent features, and patent trading specifications) and regression model, a patent trading system is developed with an automatic patent appraisal function. Findings Based on the case study, it is found that the system performance is better if the non‐critical factors can be identified and dropped out from the appraisal model. Practical implications The proposed model and platform can enhance patent trading performance and, therefore, the enterprise R&D tasks can be accomplished more efficiently. Originality/value This study proposes quantitative models of patent appraisal factors and a multiple regression model for patent appraisal to present an automatic patent price determination mechanism.
Robust snapshot interferometric spectropolarimetry (2016)

This Letter describes a Stokes vector measurement method based on a snapshot interferometric common-path spectropolarimeter. The proposed scheme, which employs an interferometric polarization-modulation module, can extract the spectral polarimetric parameters Ψ(k) and Δ(k) of a transmissive anisotropic object by which an accurate Stokes vector can be calculated in the spectral domain. It is inherently strongly robust to the object 3D pose variation, since it is designed distinctly so that the measured object can be placed outside of the interferometric module. Experiments are conducted to verify the feasibility of the proposed system. The proposed snapshot scheme enables us to extract the spectral Stokes vector of a transmissive anisotropic object within tens of msec with high accuracy.
A study of chaos in discrete-time linear systems with quantized state feedback (2005)

The authors study the chaotic behavior in a family of linear discrete-time systems with a quantized state feedback. Using the tools of dynamical system theory, they establish a necessary and sufficient algebraic condition for chaos and present a probabilistic characterization of the quasi-random chaotic behavior in this family of quantization systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
