Pharmacological modulation of CRH-stimulated ACTH secretion by ketoconazole. (1987)

The effects of ketoconazole (KC) on secretion and biosynthesis of ACTH in rat anterior pituitary cells were investigated in vitro. KC inhibits the corticotropin releasing hormone (CRH) stimulated ACTH release from rat anterior pituitary fragments in a dose dependent fashion between 1.5 and 100 microM. The effect of CRH to release ACTH was fully restored after KC was removed from the medium. Similar effects were observed in primary cultures of rat anterior pituitary cells: KC decreased dose dependently the basal and CRH stimulated ACTH release. In addition, basal and CRH-stimulated mRNA coding for the ACTH precursor was reduced after preincubation with CK. The effects of KC on ACTH release and biosynthesis seems to be mediated by cyclic AMP (cAMP) since KC inhibits basal and CRH stimulated cAMP release and content within the same dose range. Since the stimulatory effect of cholera toxin, sodium fluoride and forskolin were dose dependently inhibited by KC and since the addition of dibutyryl cAMP abolished the inhibiting effect of KC, it is concluded that KC acts by inhibition of the catalytic component of the adenylate cyclase holoenzyme.
Prostasomes, Angiogenesis, and Tissue Factor (2007)

Prostasomes are membrane-bound secretory vesicles produced by prostatic epithelial cells. They are known to carry many proteins, including tissue factor, and have membranes unusually rich in cholesterol and sphingomyelin. Prostasomes have well-documented effects on fertility, promoting sperm motility, stabilizing the acrosome reaction, and facilitating immunosuppression. This article reviews the evidence of the effects of prostasomes on in vitro angiogenesis assays, and the mechanism by which these effects occur. Seminal prostasomes seem to inhibit angiogenesis, whereas the equivalent particles released by malignant prostate cells promote angiogenesis. In both cases, the effects seem preserved after heat treatment to denature the protein content, suggesting an important role for lipid transfer, in particular, transfer of sphingomyelin.

Viscoelastic Effects On A Polyetherimide Cylinder With Constant Radial Deformation (2015)

The relaxation of an axisymmetric radially crimped joint is analyzed with the inner component being formed from the engineering grade polymer ULTEM<sup>TM</sup> 1000 polyetherimide. Creep and Relaxation tests were performed at several temperatures in order to use Time Temperature Superposition theory to assemble a master curve for predictions at long times based on short time testing.\tThe master curves for each test were fit to the appropriate Prony Series and all coefficients are tabulated for re-use. The elastic theory for the classic thick walled cylinder was reviewed and the conversion from elasticity to viscoelasticity was demonstrated. Strength predictions are shown and compared to their elastic counterparts. Finally, a non-dimensionalized model of strength over time is presented.

Wideband dual-polarised microstrip patch antenna (2001)

A dual-polarised microstrip antenna capable of achieving a wide bandwidth, a high isolation, low cross-polarisation levels and low backward radiation levels is presented. The H-shaped coupling aperture is used. For wide bandwidth and easy integration with active circuits, it uses the aperture-coupled stacked microstrip square patches. Measured return loss exhibits a bandwidth of over 20.9% and isolation is better than 36 dB over the bandwidth. Cross-polarisation levels and the front-to-back ratio are better than –22 and 21 dB, respectively.
Secondary clarifier conditions conducting to secondary phosphorus release in a BNR plant (2009)

A full-scale study at Pihlajaniemi BNR plant in Savonlinna Finland investigated in detail the conditions in which phosphorus release in the secondary clarifier can occur. For this purpose nutrient and ORP profiles were taken in different process conditions from the sludge blanket in the secondary clarifiers. The results show that in anaerobic conditions secondary phosphorus release can take place in the secondary clarifiers without any addition of exogenous COD. Long sludge retention time in the secondary clarifier was a prerequisite of anaerobic conditions in the sludge blanket, but retention time required varied with seasons and process conditions. Some indications of simultaneous phosphorus release and denitrification without COD input was also found. The re-absorption of the released phosphorus was observed in those parts of the sludge blanket, where nitrates were present. Even with very long sludge retention times the released phosphorus stayed inside the sludge blanket and it did not impair the effluent quality. An 18 month follow-up of the BNR process revealed, however, that occasionally dissolved phosphorus escaped from the sludge blanket. It was suggested, that this was the consequence of the missing nitrate containing layer at the upper part of the sludge blanket.
Biofuel Economy and Hydrogen Competition (2007)

This study analyzed how production technology progress and economic structure reformation affect the transition to biofuel or hydrogen economy in Taiwan before 2040. A model, called “Taiwan general equilibrium model––Energy for biofuel and hydrogen (TAIGEM––EBH)”, was the forecast tool, considering as well the role of four new energies, including bioethanol, biodiesel, hydrogen, and fuel cell production industries. When no effort was made to advance the biofuel and hydrogen production technologies, the energy structure in Taiwan will remain almost unchanged over time, with crude oil and coal the primary energy sources up to 2040. With technological advance to reduce production cost, bioethanol will become the dominating renewable energy source, with coal and oil the main primary energy sources as well. Only with a reformed economic structure resembling a developed country, the biofuels and hydrogen economy can be realized in Taiwan.
Increasing the frequency resolution of NCO-systems using a circuit based on a digital adder (1996)

A digital low cost solution for increasing the frequency resolution of Direct Digital Synthesizers (DDS) containing Numerically Controlled Oscillators (NCO's) is presented. The additional hardware can be used for all off-the-shelf NCO's offering a carry input of the internal phase-accumulator. Its simplicity makes it suitable for many applications, especially where cost-efficient solutions are required. An example of an actual implementation of a signal-generator using this technique is presented and described.
A BAYESIAN APPROACH TO BATTERY PROGNOSTICS AND HEALTH MANAGEMENT (2016)

This chapter deals with each of three components of battery health management (BHM): battery state estimation, battery prognostics, and decision making. The state-of-health (SOH) of batteries is a measurement that reflects the general condition of a battery and its ability to deliver the specified performance compared to a fresh battery. The chapter discusses how to determine the remaining useful life (RUL) of a battery. State estimation techniques, like the extended Kalman filter (EKF), have been applied for real-time prediction of state-of-charge (SOC) and SOH of automotive batteries. A decision-level fusion of data-driven algorithms, like Autoregressive Integrated Moving Average (ARIMA) and neural networks, have been investigated for both diagnostics and prognostics. Particle filters (PFs) are a novel class of nonlinear filters that combine Bayesian learning techniques with importance sampling to provide good state tracking performance while keeping the computational load tractable.
Classification of Fowl Adenovirus Serotypes by Use of High-Resolution Melting-Curve Analysis of the Hexon Gene Region (2008)

Identification of fowl adenovirus (FAdV) serotypes is of importance in epidemiological studies of disease outbreaks and the adoption of vaccination strategies. In this study, real-time PCR and subsequent high-resolution melting (HRM)-curve analysis of three regions of the hexon gene were developed and assessed for their potential in differentiating 12 FAdV reference serotypes. The results were compared to previously described PCR and restriction enzyme analyses of the hexon gene. Both HRM-curve analysis of a 191-bp region of the hexon gene and restriction enzyme analysis failed to distinguish a number of serotypes used in this study. In addition, PCR of the region spanning nucleotides (nt) 144 to 1040 failed to amplify FAdV-5 in sufficient quantities for further analysis. However, HRM-curve analysis of the region spanning nt 301 to 890 proved a sensitive and specific method of differentiating all 12 serotypes. All melt curves were highly reproducible, and replicates of each serotype were correctly genotyped with a mean confidence value of more than 99% using normalized HRM curves. Sequencing analysis revealed that each profile was related to a unique sequence, with some sequences sharing greater than 94% identity. Melting-curve profiles were found to be related mainly to GC composition and distribution throughout the amplicons, regardless of sequence identity. The results presented in this study show that the closed-tube method of PCR and HRM-curve analysis provides an accurate, rapid, and robust genotyping technique for the identification of FAdV serotypes and can be used as a model for developing genotyping techniques for other pathogens.
A Systematic Review of the Use of Rituximab for Desensitization in Renal Transplantation (2014)

Evidence of limited quality was identified to support the use of rituximab desensitization in highly sensitized recipients. Among ABO-incompatible recipients, rituximab was found to be equivalent to splenectomy, indicating that this invasive surgical procedure is not necessary. Further randomized controlled trials are required to better define the efficacy, long-term safety, and optimal dosing regimen of rituximab in this setting.
First Italian space debris observatory: The image processing automation (2007)

Space debris are a concern for operative satellites and human missions. A large amount of debris is located in Low Earth Orbit and in Geostationary Orbit, and several institutes all around the world monitor the growth of the debris population. Since a few years, GAUSS (Group of Astrodynamics of the University of Rome “La Sapienza”) has been carrying out space debris observation campaigns exploiting amateur astronomers’ facilities. Presently GAUSS is making up, in the frame of a contract with Italian Space Agency (ASI), the first Italian optical observa-tory completely addressed to space debris detection. During the optical campaigns, a large number of images is expected to be archived. This is the reason why a software is needed to process the images in order to automatically detect the objects and correlate them with the catalogue. The algorithm is based mainly on single-frame handling to make the noise level as flat as possible, with a successive two-image comparison which allows removing stars and bi-ases. In the object detection procedure a shape identification algorithm has been avoided, in order to reduce calculation time. The last step is the object identification by comparison with the Two-Line Elements catalogue. The actual position of the detected objects is compared with the propagated positions of the catalogued ones. In conclusion, both the image processing itself and the object identification are performed automatically. The paper describes the logic of the developed algorithm as well as the preliminary results of the software.
An online prototype speech-enabled information access tool using Java Speech Application Programming Interface (2002)

The World Wide Web today has become a major force in driving the economy, and the technology. In spite of the abundance of information freely available on the Web, the information is not accessible to everyone. There are a couple of reasons for this trend. Firstly, most of this information has primarily been used by and restricted to persons who connect and use the Web via a traditional computer. Thus access to Web information, for an increasing number of mobile device users, is very limited at this point. Secondly, most of the contents on the Web are in a format unsuitable for disabled people. Contents are either visually rich or highly structured. Proposed here is the prototype of an application tool that would provide increased access to Web information using speech technology. The implemented tool is based on distributed computing techniques to provide scalability. The tool incorporates both speech recognition and speech synthesis thereby providing complete speech input and output capability, tending towards a complete hands-free Web access. The proposed tool is implemented using a Java Speech Application Programming Interface (JSAPI) compliant speech engine which uses Java as the host language. This arrangement provides platform independence and portability to the tool. The tool is based on client-server architecture and uses remote method invocation (RMI) for distributed computational purposes. This paper provides a brief overview of the design and implementation of the application, includes discussion on current research issues and provides observations and suggestions for future enhancements.
Anonymizing user location and profile information for privacy-aware mobile services (2010)

Due to the growing use of mobile devices, location-based services have become popular. A location service often requires the user's exact location to provide appropriate services and this brings the risk of threats to privacy. In this paper, we propose an anonymization method for users of location-based services in mobile environments.

Audit system at CESNET-CERTS (2009)

CESNET-CERTS, the Computer Security Incident Response Team of the CESNET Association in Prague, Czech Republic, uses several security tools based on freely licensed programs. One of them is an enhanced system for host security auditing which is based on Nessus and runs on a PC server under Linux. An e-mail interface developed in-house allows users to perform basic host security audits simply and securely without having to study the extensive Nessus manuals and/or installing the Nessus server. The use of a similar open-source program OpenVAS within the Audit System is also considered. Key-Words: Cesnet Association, Host security audit, Nessus, OpenVas, Pc, Linux, E-mail interface
Trickle‐bed reactor performance. Part II. Reaction studies (1975)

Abstract Dilute solutions (132 ppm) of formic acid in water were oxidized with air in a trickle‐bed reactor at 212° to 240°C and 40 atm. Particles 0.291 and 0.0541 cm in diameter, prepared from a commercial CuO · ZnO catalyst, were used to provide a model system for studying water purification by catalytic oxidation. Differential reactor runs were made to measure the global rate of reaction. These data were compared with predicted rates from the known intrinsic kinetics and intraparticle diffusivities, and the mass transfer coefficients measured in Part I. High conversion (of formic acid) data were also obtained in order to test models for trickle‐bed reactors. Experimental conversions agreed reasonably well (within 10%) with predicted values based upon intrinsic kinetics and the several transport rates. Axial dispersion was found to be less important than gas‐to‐liquid mass transfer and intraparticle diffusion. In our laboratory studies (reactor I.D. = 1 in.) careful arrangements were made to obtain nearly uniform distribution of liquid over the reactor cross section. Hence effects of maldistribution, which may be important in large‐scale reactors, were minimized.
Comparison of Correction Techniques and Analysis of Errors for Digital Beamforming Antenna Array With Single RF Receiver (2012)

A new correction method is proposed for the single RF channel digital beamforming (DBF) antenna array. In this array, each array element is followed by a <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$0/\pi$</tex></formula> phase shifter, and the element outputs can be recovered by the single channel through the time sequence phase weighting (TSPW) technique. The outputs can be used to form desired beams through DBF. The performance of the DBF is influenced by the imperfection of the phase shifters. To obtain the errors in each phase shifter, the online test method based on a single known plane wave is introduced. The online test results are used to correct the element outputs using the relationship between the actual and the incorrect outputs. Compared with another previously proposed correction method, the new method is simpler and more suitable for real time correction. The factors that may influence the capability of the correction are analyzed. To validate the proposed method, an eight-element prototype is measured, and the data are used to synthesize low sidelobe patterns. Results show that the sidelobe level and gain improvements after correction are 11.1 and 2.6 dB, respectively.
Labeling Chinese Predicates with Semantic Roles (2008)

In this article we report work on Chinese semantic role labeling, taking advantage of two recently completed corpora, the Chinese PropBank, a semantically annotated corpus of Chinese verbs, and the Chinese Nombank, a companion corpus that annotates the predicate-argument structure of nominalized predicates. Because the semantic role labels are assigned to the constituents in a parse tree, we first report experiments in which semantic role labels are automatically assigned to hand-crafted parses in the Chinese Treebank. This gives us a measure of the extent to which semantic role labels can be bootstrapped from the syntactic annotation provided in the treebank. We then report experiments using automatic parses with decreasing levels of human annotation in the input to the syntactic parser: parses that use gold-standard segmentation and POS-tagging, parses that use only gold-standard segmentation, and fully automatic parses. These experiments gauge how successful semantic role labeling for Chinese can be in more realistic situations. Our results show that when hand-crafted parses are used, semantic role labeling accuracy for Chinese is comparable to what has been reported for the state-of-the-art English semantic role labeling systems trained and tested on the English PropBank, even though the Chinese PropBank is significantly smaller in size. When an automatic parser is used, however, the accuracy of our system is significantly lower than the English state of the art. This indicates that an improvement in Chinese parsing is critical to high-performance semantic role labeling for Chinese.
Stability of metal oxide nanoparticles in aqueous solutions (2010)

The application of nanoparticles in the processes of making commercial products has increased in recent years due to their unique physical and chemical properties. With increasing amount of commercial nanoparticles released into nature, their fate and effects on the ecosystem and human health are of growing concern. This study investigated the stability and morphology of three metal oxide nanoparticles in aqueous solutions. The commercially available nanoparticles, TiO(2), ZnO, SiO(2), aggregated quickly into micrometer-size particles in aqueous solutions, which may not threaten human health. Their changes in morphology and characteristics were further examined by dynamic light scattering (DLS) method and transmission electron microscopy (TEM). Among the several dispersion approaches, ultrasonication was found to be the most effective for disaggregating nanoparticles in water. For these three selected nanoparticles, ZnO could not remain stable in suspensions, presumably due to the dissolution of particles to form high concentration of ions, resulting in enhanced aggregation of particles. In addition, the existence of dissolved organic matters stabilized nanoparticles in lake water and wastewater for several hours in spite of the high concentration of cations in these real-water samples. The fate of metal oxide nanoparticles in natural water bodies would be determined by the type and concentration of cations and organic matters. Results obtained in this study revealed that the stability of nanoparticles changed under different aqueous conditions and so did their fate in the environment.
The Architecture of a Parallel Relative Debugger (2000)

Relative debugging is a technique that addresses the problem of debugging programs developed using evolutionary software techniques. Recent developments allow relative debugging to be used on programs that have been ported from serial to parallel architectures. Such programs may change significantly in the porting process, and this raises many issues for the debugging process, such as how the array data and code transformations that occur in these situations can be modelled. Relative debugging can also be effectively used in situations where the parallel programs themselves have undergone evolutionary change. This paper presents the architecture of a parallel relative debugger, and reveals a number of novel and powerful techniques that have been developed for dealing with the issues of relative debugging in a parallel environment.
A new nondestructive read for magnetic cores (1955)

A simple but effective method has been developed for reading information from ferrite storage cores without destroying the information. A single ferrite core containing a small radial hole is used per stored bit. A wire is threaded through the hole and a current pulse is passed down the wire to interrogate the core. The interrogation current temporarily disturbs the residual flux in the core and induces a signal in an output winding. The output signal is unique for the direction of the residual flux and is independent of the direction of the interrogation current.
