An Online-Offline Combined Big Data Mining Platform (2017)

Machine learning libraries are integral to a big data mining platform. There are three limitations on adopting current machine learning libraries in such a platform. First, these algorithms are not implemented for handling both online and offline big data analysis. Second, libraries exist in a variety of frameworks using different programming languages, which make it difficult in integrating several algorithms. Third, most machine learning libraries provides APIs for programming only, thus not user-friendly for those do not have a sufficient understanding of algorithms and those lack of programming skills. In this paper, we implement a comprehensive machine learning library including common algorithms and deep learning algorithms. We integrate this library at a platform level that allows both online and offline data analysis using this library. We further design a user-friendly portal that enables quick and agile data analysis practices. All of these form an Online-Offline Combined Big Data Mining Platform (OOBDP). We present a demonstration of big oil data analysis using this platform. We observe the that OOBDP can easily accommodate industrial requirement for adaptable data mining process, with personalized usage scenarios, and easy to use experiences.
A new approach to camera hand-off without camera calibration for the general scene with non-planar ground (2006)

For robust continuous tracking across multiple views for the wide surveillance environment it is helpful to know the geometric relationship or a hand-off function in addition to photometric relationship between views. Previous works for camera hand-off were mainly focused on the planar ground with homography computation or are strongly coupled with camera calibration and 3D scene recovery. In this paper, we propose a new method for camera hand-off without camera calibration for the general scene containing non-planarground.It is required to establish correspondences between views for camera hand-off. The concept of occurrence and co-ccurrence is introduced to solve the problem. We show a hand-off function can be constructed by computing the ratio of co-occurrence to occurrence for all pairs of points in two views. In addition,we analyze the cases of hand-off ambiguity and failure.Our approach to camera hand-off does not require camera calibration or 3D scene recovery.It can be applied to the scene with non-planar ground.Further-more, all operations from construction of the hand-off function to hand-off of objects across views can be performed in a full automatic manner.Experimental results for image sequences of a real outdoor scene are shown.
Bacterial Photoreceptor with Similarity to Photoactive Yellow Protein and Plant Phytochromes (1999)

A phytochrome-like protein called Ppr was discovered in the purple photosynthetic bacterium Rhodospirillum centenum. Ppr has a photoactive yellow protein (PYP) amino-terminal domain, a central domain with similarity to phytochrome, and a carboxyl-terminal histidine kinase domain. Reconstitution experiments demonstrate that Ppr covalently attaches the blue light-absorbing chromophore p-hydroxycinnamic acid and that it has a photocycle that is spectrally similar to, but kinetically slower than, that of PYP. Ppr also regulates chalcone synthase gene expression in response to blue light with autophosphorylation inhibited in vitro by blue light. Phylogenetic analysis demonstrates that R. centenum Ppr may be ancestral to cyanobacterial and plant phytochromes.
Fall detection in walking robots by multi-way principal component analysis (2008)

SUMMARY Large disturbances can cause a biped to fall. If an upcoming fall can be detected, damage can be minimized or the fall can be prevented. We introduce the multi-way principal component analysis (MPCA) method for the detection of upcoming falls. We study the detection capability of the MPCA method in a simulation study with the simplest walking model. The results of this study show that the MPCA method is able to predict a fall up to four steps in advance in the case of single disturbances. In the case of random disturbances the MPCA method has a successful detection probability of up to 90%.
Maple (2013)

Software-Defined Networking offers the appeal of a simple, centralized programming model for managing complex networks. However, challenges in managing low-level details, such as setting up and maintaining correct and efficient forwarding tables on distributed switches, often compromise this conceptual simplicity. In this pa- per, we present Maple, a system that simplifies SDN programming by (1) allowing a programmer to use a standard programming language to design an arbitrary, centralized algorithm, which we call an algorithmic policy , to decide the behaviors of an entire network, and (2) providing an abstraction that the programmer-defined, centralized policy runs, conceptually, "afresh" on every packet entering a network, and hence is oblivious to the challenge of translating a high-level policy into sets of rules on distributed individual switches. To implement algorithmic policies efficiently, Maple includes not only a highly-efficient multicore scheduler that can scale efficiently to controllers with 40+ cores, but more importantly a novel tracing runtime optimizer that can automatically record reusable policy decisions, offload work to switches when possible, and keep switch flow tables up-to-date by dynamically tracing the dependency of policy decisions on packet contents as well as the environment (system state). Evaluations using real HP switches show that Maple optimizer reduces HTTP connection time by a factor of 100 at high load. During simulated benchmarking, Maple scheduler, when not running the optimizer, achieves a throughput of over 20 million new flow requests per second on a single machine, with 95-percentile latency under 10 ms.
A Semiparametric Approach to the One-Way Layout (2001)

We consider m distributions in which the first m − 1 are obtained by multiplicative exponential distortions of the mth distribution, which is a reference. The combined data fromm samples, one from each distribution, are used in the semiparametric large-sample problem of estimating each distortion and the reference distribution and testing the hypothesis that the distributions are identical. The approach generalizes the classical normal-based one-way analysis of variance in the sense that it obviates the need for a completely specified parametric model. An advantage is that the probability density of the reference distribution is estimated from the combined data and not only from the mth sample. A power comparison with the t and F tests and with two nonparametric tests, obtained by means of a simulation, points to the merit of the present approach. The method is applied to rain-rate data from meteorological instruments.
Pet Food: The Lowdown on Labels (2001)

U.S. consumers spend more than $11 billion a year on cat and dog food, according to the Pet Food Institute. And pet food manufacturers compete for these dollars by trying to make their products stand out among the many types of dry, moist, and semi-moist foods available. Pet food packaging carries such descriptive words as senior, premium, super-premium, gourmet, and natural. These terms, however, have no standard definition or regulatory meaning.
A π-Donor Spectrochemical Series for X in (Me<sub>5</sub>C<sub>5</sub>)<sub>2</sub>TiX, and β-Agostic Interactions in X = Et and N(Me)Ph (1996)

The EPR and electronic spectra of d1-bent metallocene compounds of the type Cp*2TiX, where X is halide, alkoxide, amide, alkyl, or hydride and Cp* = Me5C5, have been studied. Several of these compounds are new, and those with X = N(Me)H and F were characterized by X-ray crystallography. The crystal structure of Cp*2TiN(Me)H showed that the N(Me)H ligand lies on the plane defined by Cp*(centroid)−Ti−Cp*(centroid). This is the sterically most unfavorable conformation but allows maximum Ti−N π-bonding. The anisotropic frozen solution EPR spectra were analyzed by the method used by Petersen and Dahl for the d1-metallocenes, Cp2VX2, which gives gx, gy, and gz. Although the values of gx and gz are relatively constant throughout the series, the value of gy varies with the π-donor ability of X. The π-donor series is N(Me)H ≈ NH2 ≈ OMe > OPh ≈ F > N(Me)Ph > Cl > Br > I > H. Among the known alkyls, the π-donor ability was Et > Me > n-Pr ≈ CH2CMe3 > CH2C6H5, which is rationalized, in part, by a β-agostic interaction in the case of Et. The β-agostic interaction in Cp*2TiEt and in Cp*2TiN(Me)Ph was investigated by variable-temperature EPR spectroscopy giving an enthalpy and entropy for the agostic interaction. For Cp*2TiEt the parameters for the agostic interaction are ΔH° = −1.93(3) kcal/mol and ΔS° = −6.3(2) eu, and for Cp*2TiN(Me)Ph, ΔH° = −1.5(1) kcal/mol and ΔS° = −7.9(5) eu.
Temporal Evolution of Susceptibility Artifacts from Coiled Aneurysms on MR Angiography: An In Vivo Canine Study (2011)

MR imaging susceptibility artifacts change with time, being maximal in the postembolization setting and decaying until 4 weeks. The clinical implications of this study are that baseline MRA for comparison with future imaging should be acquired at a minimum of 1 week after the procedure.
Poster - Thur Eve - 74: A Fan-Beam Collimator Design for Small Animal Scintigraphy (2010)

The objective of the study was to design and conduct a performance study of a fan-beam collimator for a multi-modality small-animal imaging device, which was primarily responsible yielding high-resolution images with high sensitivity - a necessity for rapid dynamic studies. The device had of a high-resolution gamma camera that included a 2×2 array of position sensitive photomultiplier tubes and a pixilated NaI(Tl) scintillator array. The collimator's holes were square-shaped to match the layout of the scintillation detector, with a septal thickness equals t the separation between two consecutive pixel elements. The collimator septal length (l), focal length (f), and septal thickness (t) were calculated. A Monte Carlo model was used to calculate the scattering and noise photons for a homogeneous 3D attenuating medium. The detector pixels were defined as repeated structures of square shaped NaI(Tl) crystal blocks (0.6 cm thick). The outer layer of the detector blocks was surrounded by vacuum to stop external scattering. The collimator was defined as intersecting tungsten plates of thickness 0.02cm each. The angular dependency of the fan-beam collimator was studied and a signal to noise index was calculated within the central field of view. The detection efficiency of the fan-beam collimator increased significantly (about 102 times more) in comparison to the parallel hole collimator when a point source was placed close to the focal point. The angular effect on the fan-beam performance showed a minor effect in comparison to that of attenuation effect. The use of the fan-beam collimator significantly increased the detection efficiency for the gamma camera.
Low-Frequency Dynamics of Homogeneous Four-Level cw Lasers (1970)

The response of homogeneously broadened four-level lasers to known pertubations is investigated theoretically and experimentally with a Nd:YAG laser. Considered are cavity loss modulations in the low-frequency range including the relaxation-oscillation regime separately from shifts of the cavity frequency. The experiments are carried out in such a way that the population inversion is also spatially homogeneous. This allows us to simplify the theories. Good agreement is obtained between experimental and theoretical results. In the case of loss modulation the laser response exhibits one sharp peak in the vicinity of relaxation oscillations. Regular pulses of high peak intensity are obtained which are controllable with very small loss modulations. In the case of a continuous shift of the cavity frequency the laser output consists of similar pulses. They occur at the relaxation-oscillation frequency independent of the rate of change of the cavity frequency. The laser frequency is shifted away from line center proportional to the third root of the rate of change of the cavity frequency. Mode locking was not found.
High power 0.98 μm InGaAs-GaAs-InGaP distributed feedback buried heterostructure strained quantum well lasers (1993)

Data are presented on device results from InGaAs-GaAs-InGaP distributed feedback buried heterostructure strained quantum well lasers entirely grown by a three step MOVPE process showing a laser threshold of 2.9 mA and a maximum monomode output power of 58 mW, both measured CW at RT. The monomode oscillation is obtained even for an injection current of 150 mA (21 times the laser threshold) with a sidemode suppression ratio of 35 dB and the Bragg wavelength at 0.98 μm and this is, to the best of the authors' knowledge, the highest CW monomode output power ever obtained from GaAs-based DFB lasers.
Interferon production by human mononuclear leukocytes: differences between respiratory syncytial virus and influenza viruses (1981)

The ability of respiratory syncytial virus (RSV) to induce interferon production by human mononuclear leukocytes was compared with that of influenza viruses. Cell culture fluids were assayed for interferon activity 1, 3 and 7 days after exposure to RSV or to one of two subtypes of influenza A virus (H0N1 and H3N2). RSV induced interferon production inconsistently and in low titers. Varying the multiplicity of infection did not improve the ability of RSV to induce interferon production. In contrast, influenza viruses were effective inducers of interferon production. Seropositivity to the influenza virus strains was not associated with increased interferon titers. Interferon produced after exposure to RSV or to the influenza viruses was resistant to low pH treatment. The data suggest that interferon production may not be a major component of human immunological defense against RSV infection.
Identification of a 29 kDa flagellar sheath protein in Helicobacter pylori using a murine monoclonal antibody (1995)

The membrane-like flagellar sheath of Helicobacter pylori is of unknown function and little is known of its composition. A murine monoclonal antibody to H. pylori, designated GF6, which reacts by immunoblot with a polypeptide with an apparent molecular mass of 29 kDa was shown by immunogold-electron microscopy to label specifically the flagellar sheath structure. The antigen was detected by immunoblot using the monoclonal antibody in all 11 strains, of diverse geographic origin, so far tested. The antibody also reacted weakly with polypeptides with apparent molecular masses of 65 kDa in Vibrio cholerae and Vibrio parahaemolyticus. The antigen was shown by one- and two-dimensional electrophoretic analysis and immunoblotting to be distinct from the abundant urease subunit UreA, of similar molecular mass. Identification of this flagellar sheath polypeptide will facilitate investigation of the structure and function of the flagellar sheath of this important gastric pathogen.
Development of serotoninergic neurons from ventricular cells of the mouse neural plate <i>in vitro</i> (1987)

Cephalic neural plates and neural tubes of mice (pros- and rhombencephalic anlagen), developmental stages Theiler 11-18 [Th 11-18; embryonic day 7 1/2-11 (E7 1/2-11)], were prepared and cultured in a plasma clot with horse serum-containing MEM medium. Differentiation of the ventricular cells was studied in order to investigate the expression of serotoninergic properties. Serotoninergic neurons were not detected in preparations derived from neural plates of stage Th 11 (E7 1/2), but were demonstrated in increasing numbers from the early stage Th 12 (E8) onwards. The exclusively originated from the rhombencephalic floor caudal to the mesencephalic flexure. The serotoninergic neurons developed from these areas, irrespective of whether being cultured in their natural position within the neural plate, or separated as microcultures, or transplanted into the prosencephalic anlage. Every other region of the neural plate remained free of serotoninergic neurons. The in vitro findings are highly reproducible due to the following properties: the morphological and immunocytochemical peculiarities of the serotoninergic neurons, their tendency to appear in increasing numbers with age, their localization within the cultured neural plates and their appearance in all cultures from stage Th 12 (E8) on. Due to these findings it is considered possible that the progenitor cells of serotoninergic neurons might already have been determined within distinct areas in the mouse neural plates as early as stage Th 12 (E8).
Targeted Disruption of the <i>Plasmodium berghei</i> Ctrp Gene Reveals Its Essential Role in Malaria Infection of the Vector Mosquito (1999)

CTRP (circumsporozoite protein and thrombospondin-related adhesive protein [TRAP]-related protein) of the rodent malaria parasite Plasmodium berghei (PbCTRP) makes up a protein family together with other apicomplexan proteins that are specifically expressed in the host-invasive stage 1. PbCTRP is produced in the mosquito-invasive, or ookinete, stage and is a protein candidate for a role in ookinete adhesion and invasion of the mosquito midgut epithelium. To demonstrate involvement of PbCTRP in the infection of the vector, we performed targeting disruption experiments with this gene. PbCTRP disruptants showed normal exflagellation rates and development into ookinetes. However, no oocyst formation was observed in the midgut after ingestion of these parasites, suggesting complete loss of their invasion ability. On the other hand, when ingested together with wild-type parasites, disruptants were able to infect mosquitoes, indicating that the PbCTRP gene of the wild-type parasite rescued infectivity of disruptants when they heterologously mated in the mosquito midgut lumen. Our results show that PbCTRP plays a crucial role in malaria infection of the mosquito midgut and suggest that similar molecular mechanisms are used by malaria parasites to invade cells in the insect vector and the mammalian host.
Precise dynamic slicing algorithms (2003)

Dynamic slicing algorithms can greatly reduce the de bugging effort by focusing the attention of the user on a relevant subset of program statements. In this paper we present the design and evaluation of three precise dynamic slicing algorithms called the full preprocessing (FP), no preprocessing (NP) and limited preprocessing (LP) algorithms. The algorithms differ in the relative timing of constructing the dynamic data dependence graph and its traversal for computing requested dynamic slices. Our experiments show that the LP algorithm is a fast and practical precise slicing algorithm. In fact we show that while precise slices can be orders of magnitude smaller than imprecise dynamic slices, for small number of slicing requests, the LP algorithm is faster than an imprecise dynamic slicing algorithm proposed by Agrawal and Horgan.
Vol. 3, No. 1, March 2010 (2010)

Governmental systems are one of the significant topics of constitutional law literature and comprehensive studies have been carried out on this issue. The answer to the question whether a parliamentary system, a presidential system or a mixed system is the most suitable system of government can change according to the political preferences of the countries. Since countries search for the best system of government, debate about "governmental system change" keep its actuality. (Note 1) Discussions about governmental system change are also not new in Turkey. Parliamentarism has been one of the defining characteristics of the Turkish constitutional system since 1876 Ottoman Constitution; however, during the application of the Constitution of 1982 first ex-president Turgut zal, then ex-president Sleyman Demirel maintained that the governmental system in Turkey needed to be changed from parliamentary system to semi-presidential or presidential system, because Turkey's growing and pressing problems require an "effective executive" which would take necessary decisions quickly and apply them effectively and the president in such systems fits this requirement. Governmental system change issue also came into question during the The Justice and Development Party Government's term of office. Both the prime minister Recep Tayyip Erdoan himself and the other senior party members occasionally mentioned that semi-presidential system would be the best governmental system for Turkey (der, 2005, p.31; Gnen, 2008, p.522; Canikliolu, 1999, p.184-186; Yavuz, 2000, p.544-556; TBMMTD, 1999, p.28).

A visual design for collaborative work: columns for commenting and annotation (2002)

Collaboration has traditionally occurred through verbal and visual communication. In recent years, technical innovation has provided a new context for collective efforts that are supported by the computer. Yet little attention has been paid to the traditional visual designs that have supported collaboration in the past. The paper describes a visually oriented design for accessing and organizing information in the context of computer supported collaborative work. The authors show how interface design with a strong emphasis on a simple yet elegant visual metaphor can facilitate collaboration by reducing clutter and focusing end-user tasks efficiently. A columnar visual interface provides a powerful interaction mechanism for supporting collaboration in general.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Generic framework for mobile application development (2011)

With the paradigm shift of applications from desktop to hand held devices, the number of mobile operating systems or platforms emerging, is enormous. Since each platform has its own architecture and interfaces, developing applications for multiple platforms is a tedious and daunting task for any mobile application developer. A framework for developing cross platform applications has become the need of the hour. This paper presents one such framework that enables the development of applications that can run on Android, BlackBerry and iOS platforms. The framework enables the developer to implement his logic in a single language. It takes care of redirecting the calls to the respective native APIs. The paper describes the features and functionality of the framework. The framework has been developed and is currently being used to build cross platform applications.
