Mutagenesis of the H-ras p21 at glycine-60 residue disrupts GTP-induced conformational change (1995)

The function of Gly-60, the conserved glycine in the DXXG domain of v-H-ras, was examined by site-directed mutagenesis. It was found that while the G60A (Gly-60 to Ala substitution) mutation has little effect on the interaction of H-ras with guanine nucleotides, it completely abolishes the biological activity of v-H-ras. The G60A mutation also exerts little effect on the interaction of H-ras with SDC25C (a guanine nucleotide exchange factor) and GAP. However, the G60A mutation does lower the ability of H-ras to bind Raf. GTP induces an enhancement of fluorescence emission in complexes consisting of H-ras and the fluorescent dye 8-anilino-1-naphthalenesulfonic acid. This enhancement is blocked by the G60A mutation. On the basis of these observations, we propose that the GTP-induced conformational change of H-ras, a process required for H-ras activities, is impaired by the G60A mutation.
Finger Localization and Classification in Images based on Generalized Hough Transform and Probabilistic Models (2006)

Modern sliding table saws are equipped with several passive safety devices. However, alone in Germany several hundred severe injuries or limb amputations occur each year. Thus an active safety system is developed in order to protect the machine user. For this purpose, a camera is applied as the main sensor system for hazard analysis. When a dangerous situation is recognized, the system triggers a rapid saw blade braking device. The hazard analysis is based on a localization and classification step. For this, the user's hand is represented by a probabilistic model relating to a feature extraction utilizing the generalized Hough transform. The described procedure works reliably, however, the computational complexity is demanding
Effectiveness Factors of Online Advertising (2012)

Research of effectiveness of online advertising show the absence of agreed factors of effectiveness. Focus has been placed on the click-through rates, rather than on attitudinal responses, and it is necessary to evaluate the effectiveness of online advertising from a more comprehensive perspective. Online advertising has sizable effects on brand loyalty and attitudes that can’t be reflected in click-through. Online advertising features force consumers to make relationship with company’s brand which leads to increase brand image in consumer’s mind. Aim is to analyze the impact of the type of online advertising format as well as specific advertisement features on user’s response and on the effectiveness of online advertising in general. The methods used: literature analysis, comparison, structured questionnaire, data analysis, observation.

Production of Reactive Oxygen Species by the Reaction of Periodate and Hydroxylamine for Rapid Removal of Organic Pollutants and Waterborne Bacteria (2020)

Periodate (PI, IO<sub>4</sub><sup>-</sup>) can be activated by hydroxylamine (HA), resulting in the rapid removal of organic pollutants within seconds. While the previous studies on PI-based advanced oxidation processes (AOPs) have proposed iodate radical (<sup>•</sup>IO<sub>3</sub>) as the major reactive species, no evidence of <sup>•</sup>IO<sub>3</sub> production was found in the present PI/HA system. Reactive oxygen species (ROS) including <sup>•</sup>OH, HO<sub>2</sub><sup>•</sup>, and <sup>1</sup>O<sub>2</sub> are proposed to be the main oxidants of the PI/HA system, which is supported by various tests employing the scavengers, chemical probes, and spin-trapping electron paramagnetic resonance (EPR) technique. To minimize the risk of toxic iodinated byproduct formation caused by reactive iodine species such as HOI and I<sub>2</sub>, the molar ratio of HA/PI was optimized at 0.6 to achieve the stoichiometric conversion of IO<sub>4</sub><sup>-</sup> to iodate (IO<sub>3</sub><sup>-</sup>), a preferred nontoxic sink of iodine species. The PI/HA system also efficiently inactivated both Gram-positive and -negative bacteria with producing <sup>1</sup>O<sub>2</sub> as the dominant disinfectant. The mechanism of ROS production was also investigated and is discussed in detail. This work offers a simple and highly efficient option for PI activation and ROS production which might find useful applications where urgent and rapid removal of toxic pollutants is needed.

Computing the ambiguity surface (1985)

The computation of the discrete ambiguity function is considered. Two straightforward methods are developed depending upon whether we write the discrete ambiguity as a filter or as a discrete Fourier transform. A modification of the transform method produces an approximation to the discrete ambiguity function, but has increased computational efficiency. This method is based on a recent work [1]. In most major applications, we need to compute limited portions of the DFT description of the discrete ambiguity function. To do so, we first pass a long sequence of "data" through a decimated FIR filter, and then use the FFT algorithm on the results. The Remez algorithm is employed to control the resulting aliasing errors. In the final section, approximation theory is applied directly to the problem of computing the discrete ambiguity function. The algorithm required to carry out the necessary computations turns out to be the same as on the prevoius approximation method based on a decimating FIR filter.
ClpXP protease degrades the cytoskeletal protein, FtsZ, and modulates FtsZ polymer dynamics (2009)

FtsZ is the major cytoskeletal protein in bacteria and a tubulin homologue. It polymerizes and forms a ring where constriction occurs to divide the cell. We found that FtsZ is degraded by E. coli ClpXP, an ATP-dependent protease. In vitro, ClpXP degrades both FtsZ protomers and polymers; however, polymerized FtsZ is degraded more rapidly than the monomer. Deletion analysis shows that the N-terminal domain of ClpX is important for polymer recognition and that the FtsZ C terminus contains a ClpX recognition signal. In vivo, FtsZ is turned over slower in a clpX deletion mutant compared with a WT strain. Overexpression of ClpXP results in increased FtsZ degradation and filamentation of cells. These results suggest that ClpXP may participate in cell division by modulating the equilibrium between free and polymeric FtsZ via degradation of FtsZ filaments and protomers.
Community Mediation in the People's Republic of China (1991)

This study investigated the mediations of ninety-seven community mediators in the People's Republic of China. The mediators' reports on two mediations each — one successful and one unsuccessful — indicated the frequency with which they use twenty-seven mediation techniques. In addition, their information revealed the strategies — assist, procedural, educate, and external reliance — they employ in their mediations. It was found that Chinese mediators utilize the same techniques and strategies in successful versus nonsuccessful mediations; yet, their techniques and strategies differ in couple (husband-wife) as opposed to noncouple disputes.

Cathodoluminescence Characteristics of Some Barium-Zinc-Silicate Phosphors with Manganese Activator (1951)

Spectral distribution curves of cathode‐ray‐excited barium‐zinc‐silicate phosphors with manganese activator show the existence of blue, green, and red emission bands. The emission intensity of different bands was found to vary both with host crystal proportions and manganese content.
Potential prophylactic antitumor activity of retinylidene 1,3-diketones (1980)

Treatment of all-trans-retinal with a series of 1,3-diketones using Knoevenagel conditions gave the expected condensation products. These retinylidene 1,3-diketones were characterized and their biological activities in the hamster tracheal organ culture test measured. It was found that the cyclohexane- 1,3-dione derivatives are highly active in this in vitro assay, while other 1,3-diketones are less active. Retinylidenedimedone has been chosen for further evaluation.

Spilling: Expanding Hand held Interaction to Touch Table Displays (2007)

We envision a nomadic model of interaction where the personal computer fits in your pocket. Such a computer is extremely limited in screen space. A technique is described for "spilling" the display of a hand held computer onto a much larger table top display surface. Because our model of nomadic computing frequently involves the use of untrusted display services we restrict interactive input to the hand held. Navigation techniques such as scrolling or turning the display can be expressed through the table top. The orientation and position of the hand held on the table top is detected using three conductive feet that appear to the touch table like three finger touches. An algorithm is given for detecting the three touch positions from the table's sensing mechanism.
Tin oxide gas sensor fabricated using CMOS micro-hotplates and in-situ processing (1993)

A monolithic tin oxide (SnO/sub 2/) gas sensor realized by commercial CMOS foundry fabrication (MOSIS) and postfabrication processing techniques is reported. The device is composed of a sensing film that is sputter-deposited on a silicon micromachined hotplate. The fabrication technique requires no masking and utilizes in situ process control and monitoring of film resistivity during film growth. Microhotplate temperature is controlled from ambient to 500 degrees C with a thermal efficiency of 8 degrees C/mW and thermal response time of 0.6 ms. Gas sensor responses of pure SnO/sub 2/ films to H/sub 2/ and O/sub 2/ with an operating temperature of 350 degrees C are reported. The fabrication methodology allows integration of an array of gas sensors of various films with separate temperature control for each element in the array, and circuits for a low-cost CMOS-based gas sensor system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Trading Mechanisms in Securities Markets (1992)

ABSTRACT This paper analyzes price formation under two trading mechanisms: a continuous quote‐driven system where dealers post prices before order submission and an order‐driven system where traders submit orders before prices are determined. The order‐driven system operates either as a continuous auction , with immediate order execution, or as a periodic auction , where orders are stored for simultaneous execution. With free entry into market making, the continuous systems are equivalent. While a periodic auction offers greater price efficiency and can function where continuous mechanisms fail, traders must sacrifice continuity and bear higher information costs.
Response of Six Grape Cultivars to the Combined Effects of High Salinity and Rootzone Waterlogging (1984)

Abstract The effect of rootzone salinity (0 to 90 mM NaCl) on shoot growth of 6 grape cultivars [‘Sultana’ (syn. ‘Thompson Seedless’), ‘Carbernet Sauvignon’, ‘Crouchen’, ‘Shiraz’, ‘Doradillo’ and ‘Palomino’] grown as rooted cuttings was determined in sand cultures. Relative shoot growth values over 23 days with salt were ‘Palomino’ 100, ‘Sultana’ 94, ‘Shiraz’ 87, ‘Crouchen’ 83, ‘Cabernet Sauvignon’ 63, and ‘Doradillo’ 59. Application of concurrent waterlogging (anaerobiosis) stress on the root system depressed shoot growth more than salt stress alone and changed the ranking for shoot growth. Waterlogging increased total uptake of Na and Cl, increased the amount of Na and Cl transported into the shoots, and resulted in visible leaf damage within 5 days of the onset of the waterlogging.
Coping with the impact of AIDS. (1998)

While some countries still have the chance to avert a major AIDS epidemic, others are already dealing with widespread HIV infection. All patients who have illnesses for which treatment does not affect transmission, regardless of cause, should be equally eligible for public assistance. Furthermore, governments should focus upon helping poor people equally, regardless of the cause of their poverty. The first and most basic impact of HIV/AIDS is upon those people who contract the disease. As AIDS cases begin to appear, governments should move quickly to ensure that health personnel and people with AIDS know how to obtain and use the necessary drugs. However, due to their high cost, the most aggressive therapies against HIV infection and AIDS are currently unavailable and unfeasible for widespread use in developing countries . A generalized AIDS epidemic also taxes the health care system, increasing the demand for medical care and reducing the supply of care at a given quality and price. The third major impact of an AIDS epidemic is upon households and the extent and depth of national poverty. In addition to working to prevent the spread of HIV infection, governments can help ease the varied impacts of HIV/AIDS by prohibiting discrimination against HIV-infected people in health care settings and in the work force, and by strengthening anti-poverty policies.
Biosurfactant production by <b> <i>Pseudomonas aeruginosa</i> </b> GS3 from molasses (1997)

Pseudomonas aeruginosa GS3 produces rhamnolipid biosurfactants during growth on molasses and cornsteep liquor as the primary carbon and nitrogen sources, respectively. After 96 h of growth the culture supernatant fluid had a rhamnose concentration of 0·24 g l−1 and reduced the interfacial tension against crude oil from 21 mN m−1 to 0·47 mN m−1. The rhamnolipids were able to form stable emulsions with n‐alkanes, aromatics, crude oil and olive oil. These studies indicate that renewable, relatively inexpensive and easily available resources can be used for important biotechnological processes.
Term-frequency Based Feature Selection Methods for Text Categorization (2010)

A major difficulty of text categorization is the high dimensionality of the feature space. Feature selection is an important step in text categorization to reduce the feature space. Automatic feature selection methods such as document frequency thresholding (DF), information gain (IG), mutual information (MI), and so on are commonly applied in text categorization, but they do not use term frequency information. In this paper, we put forward improved DF, improved IG and improved MI methods which use term frequency information. Experiments show that our improved methods are seen notable improvements in the performance than the original DF, IG and MI methods.
Concomitant immunity and specific depression of immunity by residual or reinjected syngeneic tumor tissue. (1971)

Summary Mice given injections of living methylcholanthrene-induced fibrosarcoma cells after the complete surgical removal of a growing, sensitizing tumor implant showed a strong immune resistance to the growth of the injected cells. If the sensitizing tumor was left in situ until 4 days after the challenge injection of tumor cells or if the tumor was killed with irradiation and left to regress, the immune resistance of the host was impaired but not abrogated. The depression was specific, since the presence of a growing, antigenically unrelated tumor did not impair the resistance to the sensitizing fibrosarcoma. Injection of graded doses of killed tumor cells of the fibrosarcoma and of the antigenically unrelated tumor, a mammary carcinoma, showed that, at moderate and low doses, only the injection of fibrosarcoma cells depressed host resistance. Large doses of either tumor depressed host resistance, probably in part because of nonspecific toxic depression.
Modeling performance of a parallel streaming engine (2013)

While data are growing at a speed never seen before, parallel computing is becoming more and more essential to process this massive volume of data in a timely manner. Therefore, recently, concurrent computations have been receiving increasing attention due to the widespread adoption of multi-core processors and the emerging advancements of cloud computing technology. The ubiquity of mobile devices, location services, and sensor pervasiveness are examples of new scenarios that have created the crucial need for building scalable computing platforms and parallel architectures to process vast amounts of generated streaming data. In practice, efficiently operating these systems is hard due to the intrinsic complexity of these architectures and the lack of a formal and in-depth knowledge of the performance models and the consequent system costs. The Actor Model theory has been presented as a mathematical model of con- current computation that had enormous success in practice and inspired a number of contemporary work in this area. Recently, the Storm system has been presented as a realization of the principles of the Actor Model theory in the context of the large scale processing of streaming data. In this paper, we present, to the best of our knowledge, the first set of models that formalize the performance characteristics of a practical distributed, parallel and fault-tolerant stream processing system that follows the Actor Model theory. In particular, we model the characteristics of the data flow, the data processing and the system management costs at a fine granularity within the different steps of executing a distributed stream processing job. Finally, we present an experimental validation of the described performance models using the Storm system.
