Overview of Content-based Image Feature Extraction Methods (2013)

The technology of Image feature extraction, which is based on the subject of computer vision and image processing, use computer technology to determine the image of the invariant information and extract it to handle the actual problem. Based on the basic principle of image processing, the underlying characteristics of image and semantic feature extraction algorithm were introduced detailed in this paper.
Towards 3D reconstruction of endoscope images using shape from shading (2002)

The 3D reconstruction problem from a single endoscope image of a smooth object is studied in the context of the shape from shading methods and considering a single light source at the camera projection center. Based on a curve expansion shape from shading algorithm, a spherical projection model for the endoscope camera and a dichromatic model for the surface reflectance, an approach to solve practical problems, namely the endoscope image distortion and the removal of the image specular reflection component, is presented. Results obtained from application of this approach to synthetic and real images are presented.
Control algorithms of inelastic resistance forces of hydropneumatic springs (2016)

A control algorithms for inelastic resistance forces of hydropneumatic springs have been developed at the Volgograd State Technical University. On their basis, new design schemes of hydropneumatic springs are created. These springs provide: 1) decrease of inelastic resistance for small vibration in the area of static suspension deformation and changing direction of suspension deformation at high vibration; 2) automatic increase of inelastic resistance in the beginning of high vibration in the compression stroke with its subsequent preservation in the whole suspension stroke during several vibration periods. The authors also conducted a theoretical study of these control algorithms, which confirmed the positive impact of these algorithms on vibration isolation properties of the vehicle.
Northern light: new search engine for the Web and full-text articles (1998)

Northern Light Serach was introduced in august 1997. This search engine made two significant steps forward. First, the database searches both Web pages and full-text articles: secondly, Northern Light sorts its search results into folders based on keywords, source, and other criteria. Rather than relying on advertising dollars to support this free search engine, the plan is to support the effort through the sale of the full text articles
The ‘Queen Square bladder stimulator’: a device for assisting emptying of the neurogenic bladder (1997)

Suprapubic vibration is an effective means of emptying the neurogenic bladder in patients who are not severely disabled and who have detrusor hyper-reflexia. It probably acts through a tonic vibration reflex which is under supraspinal influence. This device may be a useful alternative to clean intermittent self-catheterization.
Understanding the effects and implications of compute node related failures in hadoop (2012)

Hadoop has become a critical component in today's cloud environment. Ensuring good performance for Hadoop is paramount for the wide-range of applications built on top of it. In this paper we analyze Hadoop's behavior under failures involving compute nodes. We find that even a single failure can result in inflated, variable and unpredictable job running times, all undesirable properties in a distributed system. We systematically track the causes underlying this distressing behavior. First, we find that Hadoop makes unrealistic assumptions about task progress rates. These assumptions can be easily invalidated by the cloud environment and, more surprisingly, by Hadoop's own design decisions. The result are significant inefficiencies in Hadoop's speculative execution algorithm. Second, failures are re-discovered individually by each task at the cost of great degradation in job running time. The reason is that Hadoop focuses on extreme scalability and thus trades off possible improvements resulting from sharing failure information between tasks. Third, Hadoop does not consider the causes of connection failures between its tasks. We show that the resulting overloading of connection failure semantics unnecessarily causes an otherwise localized failure to propagate to healthy tasks. We also discuss the implications of our findings and draw attention to new ways of improving Hadoop-like frameworks.
Synthesis and characterization of novel pyrazolone derivatives (2014)

The reactivity of hydrogen atoms at C-4 of pyrazolone 3 towards condensation reactions was studied by its reaction with p -anisaldehyde, malononitrile and/or ethyl acetoacetate in the presence of ammonium acetate and/or piperidine, glucose, phenyl isothiocyanate, 2-amino thiazole and aniline to afford compounds 4 - 6 , 13 , 15 , 17 and 18 , respectively. Reaction of amino carbonitrile 4 with ammonium thiocyanate, and formamide afforded compound 7 and pyrazolo[3,4-b]pyridinylformamide, 9 . Reaction of compound 7 with hydrazine hydrate gave thiocyanato-1,3,4-thiadiazol-2-yl)-1 H -pyrazolo[3,4-b]pyridin-6-amine derivative, 8 . Acetylation of amino carbonitriles 4 and 5 afforded compound 10 and 11 , respectively. Reaction of compound 11 with hydrazine hydrate afforded azanediyl compound 12 . The pyrazolone 19 reacted with different nitrogen nucleophiles such as hydrazine hydrate, urea, thiourea and hydroxylamine hydrochloride to afford compounds 22 - 25 . The reactivity of pyrazolone 19 as an α,β-unsaturated compound towards several carbon nucleophiles under Michael reaction was studied by its reaction with ethyl acetoacetate, ethyl cyanoacetate, and malononitrile under different reaction conditions and pyrazolone 3 to afford compounds 26 - 32 , respectively. Synthesis of amino carbonitriles 5 , pyrazolone 19 and pyrazolo[3,4-c]pyrazole 22 were carried out under microwave irradiation. The newly synthesized compounds were characterized by IR, 1 H NMR and mass spectral data.
Rapid Reaction of Hydrogen Sulfide with the Neutrophil Oxidant Hypochlorous Acid to Generate Polysulfides (2010)

H₂S has been recognized as a signaling molecule and mediator of inflammation. Here, we report the kinetics and mechanism of its reaction with the neutrophil oxidant hypochlorous acid. Stopped flow studies, carried out at high pH, showed this reaction to be extremely fast, with a second-order rate constant extrapolated to be 2 × 10⁹ M⁻¹ s⁻¹ at pH 7.4. The reaction produces polysulfides rather than polythionates and may represent a novel pathway for protein Cys-sulfhydration, a recently proposed mechanism for H₂S signaling.
A mobile agent framework for telecardiology (2005)

It is generally recognised that telecommunications and the internet in particular are changing the way healthcare is delivered in cardiology. Current. implementations of telecardiology are often characterised by a centralised approach. Within this set-up a central system is connected to various remote sites. The central system has to keep track of the activities and of the state of these sites through constant communication with them. This scheme requires large volumes of data, particularly in the case of electrocardiograms (ECGs), to be generated in the remote sites and then to be transmitted to a central control system. This often leads to bottlenecks in communication that may adversely affect the quality of care. In this paper we propose a decentralised approach based on a combination of mobile agents (MA) and an Object Request Broker (ORB) mechanism. Its main aim is to support interoperability and to optimise the monitoring processes by reducing unnecessary communication. MAs possess a degree of autonomy that enables them to filter data on the remote site, and thus ease the load on the central monitoring system. they have the added advantage that they can be customised to meet individual needs. The ORB mechanism is incorporated in order to increase the reliability of MAs and to facilitate the integration of various ECG analysis software systems available on the market. It is expected that the proposed system will provide a framework for improved monitoring of patients and will lead therefore to better healthcare in cardiology.
A CCD image preprocessor for Hadamard transform operations (1980)

A simple preprocessor structure is presented that uses external ROM or microprocessor control to implement the Hadamard transform efficiently in CCD devices.
Investigating Religious “Identity” (2013)

This article describes a fieldwork case study which integrates religious studies with various discourse analytic methods, to examine how contemporary Christian identities are represented in conversation. Based on interviews and focus groups with 46 residents of a small town in rural Canada, this research is primarily concerned with religious talk – in particular, with the “social practice” (Fairclough and Wodak, 1997: 258) of “talking [religious] identity” (Hadden and Lester, 1978). In this article, I will review briefly how “identity” is conceptualized in contemporary discourse analysis studies, before describing both the challenge of selecting appropriate linguistic methods for the investigation of religious identity, and the impact upon my research of adopting particular methods.
An Interactive Computer Approach to Tolerance Analysis (1970)

An interactive technique for statistical tolerance analysis has been developed for a computer with graphic display. The computer program called TAP provides for random perturbation of parameter values, repeated evaluation of system performance, and display of distribution histograms. The interactive capability of the program enables the designer to introduce modifications to the system so that the relative effects of these changes can be quickly evaluated with the graphic display. The program has been implemented on a computer facility consisting of a CDC 3300 digital computer, an ITT digital display scope, and an EAI 8800 analog computer. Two applications are discussed to illustrate the adaptability of the technique to either linear or nonlinear problems. The digital simulation of an active circuit is used to show how the interaction with graphic display saves time in evaluating alternative designs. A hybrid simulation of an equalizer for a digital transmission system illustrates that complex time domain problems can be economically analyzed using TAP. In addition, it is shown how TAP is used to measure the reproducibility of an analog simulation.

Abnormal frontal lobe phosphorous metabolism in bipolar disorder (1995)

This preliminary study provides support for abnormal frontal lobe phosphorous metabolism in bipolar disorder.
Cytokine release syndrome (2018)

The field of immunotherapies including monoclonal antibodies and cellular therapies is rapidly evolving and cytokine release syndrome is an obstacle to deal with in this process. This syndrome is a kind of toxic condition caused by the pro-inflammatory cytokines released with the activation of the extreme immune response. In fact, up to some extent, the cytokine release may be an indicator of the antitumor effects of immune-based therapies. Therefore, the distinction between the level at which the efficiency of treatment is ensured and the point at which the life-threatening cytokine release syndrome starts is critically important. Recently, considerable developments have been achieved with regard to the prevention or control of this syndrome. In this review it is aimed to summarize the clinical approach to cytokine release syndrome and associated conditions.
Prognostic significance of a complete pathological response after induction chemotherapy in operable breast cancer (2002)

Only a few papers have been published concerning the incidence and outcome of patients with a pathological complete response after cytotoxic treatment in breast cancer. The purpose of this retrospective study was to assess the outcome of patients found to have a pathological complete response in both the breast and axillary lymph nodes after neoadjuvant chemotherapy for operable breast cancer. Our goal was also to determine whether the residual pathological size of the tumour in breast could be correlated with pathological node status. Between 1982 and 2000, 451 consecutive patients were registered into five prospective phase II trials. After six cycles, 396 patients underwent surgery with axillary dissection for 277 patients (69.9%). Pathological response was evaluated according to the Chevallier's classification. At a median follow-up of 8 years, survival was analysed as a function of pathological response. A pathological complete response rate was obtained in 60 patients (15.2%) after induction chemotherapy. Breast tumour persistence was significantly related to positive axillary nodes (P=5.10(-6)). At 15 years, overall survival and disease-free survival rates were significantly higher in the group who had a pathological complete response than in the group who had less than a pathological complete response (P=0.047 and P=0.024, respectively). In the absence of pathological complete response and furthermore when there is a notable remaining pathological disease, axillary dissection is still important to determine a major prognostic factor and subsequently, a second non cross resistant adjuvant regimen or high dose chemotherapy could lead to a survival benefit.
Erythrocyte Folate Extraction and Quantitative Determination by Liquid Chromatography–Tandem Mass Spectrometry: Comparison of Results with Microbiologic Assay (2005)

Hemolysate incubation up to 2 h at 37 degrees C is not adequate for full polyglutamate deconjugation. We obtained the highest yield of FMGs with lowest FDG concentrations at pH 4.7/37 degrees C for 3 h. Delaying hemolysis of WB for several days had no negative effect on measurable folate for presumed MTHFR C/C genotype samples.
Der Benchmark-Test (1990)

Unter "benchmark" versteht man ein Programm zum Testen der Leistungsfähigkeit verschiedener Computer oder Mikroprozessoren. Es wird auch zum Testen der Leistungsfähigkeit eines File Servers verwendet. Das Programm enthält deshalb die wichtigsten und am häufigsten benutzten Befehle und erlaubt einen Vergleich von Verarbeitungsgeschwindigkeit und Speicherplatzbedarf zwischen verschiedenen Systemen. Ziel ist es, möglichst viele Daten in möglichst kurzer Zeit über das Netz vom Sender zum Empfänger zu transportieren.
The Glucose-regulated Nuclear Localization of Hexokinase 2 in Saccharomyces cerevisiae Is Mig1-dependent (2004)

Two major mediators of glucose repression in Saccharomyces cerevisiae are the proteins Mig1 and Hxk2. The mechanism of Hxk2-dependent glucose repression pathway is not well understood, but the Mig1-dependent part of the pathway has been elucidated in great detail. Here we report that Hxk2 has a glucose-regulated nuclear localization and that Mig1, a transcriptional repressor responsible for glucose repression of many genes, is required to sequester Hxk2 into the nucleus. Mig1 and Hxk2 interacted in vivo in a yeast two-hybrid assay and in vitro in immunoprecipitation and glutathione S-transferase pull-down experiments. We found that the Lys(6)-Met(15) decapeptide of Hxk2, which is necessary for nuclear localization of the protein, is also essential for interaction with the Mig1 protein. Our results also show that the Hxk2-Mig1 interaction is of physiological significance because both proteins have been found interacting together in a cluster with DNA fragments containing the MIG1 site of SUC2 promoter. We conclude that Hxk2 operates by interacting with Mig1 to generate a repressor complex located in the nucleus of S. cerevisiae during growth in glucose medium.
Spectroscopy of Hydrothermal Reactions. 14. Kinetics of the pH-Sensitive Aminoguanidine−Semicarbazide−Cyanate Reaction Network (1999)

Infrared spectroscopy in conjunction with an optically accessed flow reactor enable real-time concentration measurements to be made on species involved in hydrothermal reactions. The kinetics of the reaction of the aqueous cyanate ion, OCN-, at 110−160 °C and 275 bar were determined at pH = 3.94−10.5. These kinetics are useful because OCN- is frequently the precursor to the NH3 and CO2 products seen during the hydrothermolysis of organic amines. Three rate constants were needed to model the cyanate reaction. These rates were then used to model the hydrothermolysis kinetics of the progressively more complex reactions of the isoelectronic cations of semicarbazide (T = 140−170 °C) and aminoguanidine (T = 190−260 °C) in neutral and acidic solutions. Six internally consistent rate constants were obtained in order to specify the reaction network.
Optimal cumulant domain filtering (2002)

This paper presents a new technique which exploits constrained optimization methods to derive optimal two dimensional filters in the cumulant domain for processing signals in non-Gaussian noise, or signals with corrupting interferences which have non-symmetrical probability density functions. The approach proposed for enhancing signals in such noise is important, as increasingly practical engineering application areas are identifying occasions where the perceived wisdom of modelling signals in additive Gaussian noise simply does not hold. Since the bispectrum of non-Gaussian noise and interference is not zero, it corrupts the bispectrum of the signal. Thus filters that suppress the bispectral component of the noise and enhance the signal bispectrum, are required. The two dimensional filters proposed have the property of concentrating the filter energy into a hexagonal region in the bispectral domain. This leads to an impulse response for these filters which represents a new form of two dimensional discrete prolate spheroidal sequence. The sensitivity of cumulant determination to non-Gaussian noise has been noted in the area of array processing. However this paper presents one of the first attempts to remove non-Gaussian noise by cumulant filtering.
Interferon Regulatory Factor 1 Is Required for Mouse <i>Gbp</i> Gene Activation by Gamma Interferon (1995)

Full-scale transcriptional activation of the mouse Gbp genes by gamma interferon (IFN-gamma) requires protein synthesis in embryonic fibroblasts. Although the Gbp-1 and Gbp-2 promoters contain binding sites for transcription factors Stat1 and IFN regulatory factor 1 (IRF-1), deletion analysis revealed that the Stat1 binding site is dispensable for IFN-gamma inducibility of Gbp promoter constructs in transfected fibroblasts. However, activation of the mouse Gbp promoter by IFN-gamma requires transcription factor IRF-1. Transient overexpression of IRF-1 cDNA in mouse fibroblasts resulted in high-level expression of Gbp promoter constructs. Unlike wild-type cells, IRF-1% embryonic stem cells lacking functional transcription factor IRF-1 contained very low levels of Gbp transcripts that were not increased in response to differentiation or treatment with IFN-gamma. Treatment of IRF-1% mice with IFN-gamma resulted in barely detectable levels of Gbp RNA in spleens, lungs, and livers, whereas such treatment induced high levels of Gbp RNA in the organs of wild-type mice. These observations suggest two alternative pathways for transcriptional induction of genes in response to IFN-gamma: immediate response that results from activation of preformed Stat1 and delayed response that results from induced de novo synthesis of transcription factor IRF-1.

Thus TQ and CDDP appear to be an active therapeutic combination in lung cancer.
Plaque vulnerability and related coronary event prediction by intravascular ultrasound with virtual histology: “It's a long way to tipperary”? (2007)

Identification of so-called "vulnerable plaque" or "high-risk" plaques have spawned manifold attempts to develop diagnostic tools capable to afford this task. This task is particularly challenging but the reward is high: local intervention on identified "vulnerable plaque" could preclude plaque thrombosis and possibly prevent acute coronary syndromes. Various imaging techniques are currently under investigation by extensive clinical testing to identify which could become the most sensible and specific modality for vulnerable plaque detection. Noninvasive techniques are fascinating for their easily applicability to a broad population but nowadays are not sufficiently powered for this task. The emerging technologies with the greatest resolution are indeed catheter-based and many intravascular modalities have been developed for identification of "vulnerable plaque". Among these, IVUS-Virtual Histology (IVUS-VH) is the most promising technique in the field. IVUS-VH offers an in vivo opportunity to assess plaque morphology and histology. IVUS-VH uses underlying frequency information along with echoes intensity, while grey-scale IVUS data are obtained from echoes of different intensity or amplitude. The major advantage of IVUS-VH is that it is based on a device that is practical for use in the clinical setting and that it generates a real-time assessment of plaque morphology. Unfortunately, numerous challenging issues still need to be overcome until the numerous "vulnerable plaques" could be identified and successfully treated. Future efforts may identify plaques that are on a trajectory of evolution toward a vulnerable state, and help us target interventions to those plaques most likely to develop plaque disruption and related complications.
A near-infrared fiber Raman oscillator tunable from 1.07 to 1.32 μm (1979)

We report a near-infrared fiber Raman oscillator in the 1.1–1.3-μm spectral region. The Raman medium is an 800-m-long 6.3-μm-core-diam single-mode fiber with a loss less than 2 dB/km near 1.2 μm and less than 4 dB/km over the 1–1.32-μm spectral range. The oscillator is synchronously pumped by a cw mode-locked Nd : YAG laser. With four separate resonator mirrors, four orders of Stokes oscillations, peaked near 1.12, 1.18, 1.24, and 1.31 μm, are obtained. With simultaneous tuning of all the four Stokes wavelengths we have achieved continuously tunable oscillation over 250 nm (1.07–1.32 μm), the first such broadly tunable laser in this spectral range.
