A broker-less participatory sensing scheme by user matching mechanism based on market price approach (2016)

Sensing user activities and environmental conditions have been popular by using high functional sensor devices like smartphones. In modern data collection and utilization models such as participatory sensing and crowdsensing, some users provides data sensed from their smartphones while others collect these data via the clouds and servers. Reflecting providers policy is strongly required because collected data using such models may include provider's privacy. We have studied a new server-less participatory sensing application model in which users are able to flexibly control their data flow based on their own providing policy appropriate for receivers. In this paper, we improve negotiation mechanism among users by introducing the market price based user matching mechanism. We also confirm its feasibility and effectiveness through simulation results.
Time-averaging equivalent circuit analysis and controller design of full-bridge parallel resonant DC/DC converters (2002)

The time-averaging equivalent circuit model of the full-bridge parallel resonant converter operating in the discontinuous-conduction mode is set forth. This model is used to design a phase-lead controller for the converter which ensures good response, internal and overall system stability, and robustness to modeling uncertainties for all possible operating conditions. Computer simulation and experimental results of a 100 W, 500 kHz converter indicate that the controlled converter shows improvements over the open-loop system in terms of good transient response and good disturbance rejection to input voltage and output load variations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Bone Inductive Capacity of Various Bone Transplanting Materials Used for Treatment of Experimental Bone Defects (1979)

The bone defect repairing capacities of autogenous cancellous bone (ACB), decalcified bone (DB), autodigested "low-antigenic" bone matrix (LBM) and preserved bone (PB) were tested in experimental defects in rabbit scapulae. The healing of the defects was most effective with ACB transplants as judged by roentgenologic and microscopic studies. The DB and LBM transplants caused states of healing comparable to each other, and the PB transplants showed the least satisfactory results in this experiment. The ACB, DB and LBM transplants caused bone induction, which resulted in the formation of new bone, subsequent resorption of the transplanted material and rapid reshaping of the callus. The PB transplants caused no bone induction; only some growth of callus on the edges of the defect was observed and pieces of the transplanted material were seen as late as 10 weeks after the operation as dead particles encapsulated by fibrous tissue. The infiltrations of inflammatory cells around the PB transplants indicated a considerable host versus graft reaction whereas this reaction was less with the other materials tested.
Possible mechanisms of oxygen sensing in the pulmonary circulation. (1991)

Oxygen tension is known to control the pulmonary vascular tone. We reviewed three hypotheses that try to explain the mechanism whereby hypoxia is sensed in the lung tissue. The first hypothesis concerns the role of the oxygen binding hemoprotein cytochrome P-450. Studies using various inhibitors and activators of cytochrome P-450 show that this enzyme affects pulmonary vascular tone. The data are, however, contradictory. The second hypothesis postulates that hypoxia reduces the synthesis of vasodilator oxygen radicals in the lung. This hypothesis is quite well supported by experimental data. The third hypothesis, similarly widely documented, states that slowing of the respiratory chain and altered cellular energetics is crucial for sensing of hypoxia. In this case, however, it is not exactly clear how changes in cellular energetics are connected with vascular tone. The possibility exists that changes in both the cytochrome P-450 activity and in the rate of electrons flow in the respiratory chain may alter the amount of oxygen radicals in the cells and, similarly as in the "oxygen radicals" hypothesis, govern calcium channels through the control of the redox status of these channels.
Speech emotion recognition using hidden Markov models (2001)

This paper introduces a first approach to emotion recognition using RAMSES, the UPC’s speech recognition system. The approach is based on standard speech recognition technology using hidden semi-continuous Markov models. Both the selection of low level features and the design of the recognition system are addressed. Results are given on speaker dependent emotion recognition using the Spanish corpus of INTERFACE Emotional Speech Synthesis Database. The accuracy recognising seven different emotions—the six ones defined in MPEG-4 plus neutral style—exceeds 80% using the best combination of low level features and HMM structure. This result is very similar to that obtained with the same database in subjective evaluation by human judges. Dealing with the speaker’s emotion is one of the latest challenges in speech technologies. Three different aspects can be easily identified: speech recognition in the presence of emotional speech, synthesis of emotional speech, and emotion recognition. In this last case, the objective is to determine the emotional state of the speaker out of the speech samples. Possible applications include from help to psychiatric diagnosis to intelligent toys, and is a subject of recent but rapidly growing interest [1]. This paper describes the TALP researchers first approach to emotion recognition. The work is inserted in the scope of the INTERFACE project [2]. The objective of this European Commission sponsored project is “to define new models and implement advanced tools for audio-video analysis, synthesis and representation in order to provide essential technologies for the implementation of large-scale virtual and augmented environments. The work is oriented to make man-machine interaction as natural as possible, based on everyday human communication by speech, facial expressions and body gestures.” In the field of emotion recognition out of speech, the main goal of the INTERFACE project will be the construction of a real-time multi-lingual speaker independent emotion recogniser. For this purpose, large speech databases with recordings from many speakers and languages are needed. As these resources are not available yet, a reduced problem will be addressed first: emotion recognition in multi-speaker language dependent conditions. Namely, this paper deals with the recognition of emotion for two Spanish speakers using standard hidden Markov models technology.
The filamentous morphotype Eikelboom Type 1863 is not a single genetic entity (1997)

Five isolates of a filamentous bacterial morphotype with the distinctive diagnostic microscopic features of Eikelboom Type 1863 were obtained from activated sludge sewage treatment plants in Victoria, Australia. On the basis of phenotypic evidence and 16S rDNA sequence data, these isolates proved to be polyphyletic. Two (Ben 06 and Ben 06C) are from the Chryseobacterium subgroup which is in the Cytophaga group, subdivision I of the Flexibacter-Cytophaga-Bacteroides phylum. Two (Ben 56 and Ben 59) belong to the genus Acinetobacter, and one (Ben 58) is a Moraxella sp., closest to Mor. osloensis. The significance of these findings to the reliance on microscopic features for identification of these filamentous bacteria in activated sludge is discussed.
Telokin expression and the effect of hypoxia on its phosphorylation status in smooth muscle cells from small and large pulmonary arteries (2008)

Small pulmonary arteries (SPA), <500 microm diameter of the cat, constrict when exposed to hypoxia, whereas larger arteries (large pulmonary arteries; LPA), >800 microm diameter, show little or no response. It is unknown why different contractile responses occur within the same vascular bed, but activator or repressor proteins within the smooth muscle cell (SMC) can modify myosin phosphatase and myosin light chain kinase (MLCK), thereby influencing the phosphorylation state of myosin light chain (MLC) and ultimately, contraction. Telokin, a protein with a sequence identical to the COOH-terminal domain of MLCK, is expressed in smooth muscle where in its phosphorylated state it inhibits myosin phosphatase, binds to unphosphorylated myosin, and helps maintain smooth muscle relaxation. We measured telokin mRNA and telokin protein in smooth muscle from different diameter feline pulmonary arteries and sought to determine whether changes in the phosphorylation status of telokin and MLC occurred during hypoxia. In pulmonary arteries, telokin expression varied inversely with artery diameter, but cerebral arteries showed neither telokin protein nor telokin mRNA. Although telokin and MLC were distributed uniformly throughout the SPA muscle cell cytoplasm, they were not colocalized. During hypoxia, telokin dephosphorylated, and MLC became increasingly phosphorylated in SPA SMC, whereas in LPA SMC there was no change in either telokin or MLC phosphorylation. When LPA SMC were exposed to phenylephrine, MLC phosphorylation increased with no change in telokin phosphorylation. These results suggest that in SPA, phosphorylated telokin may help maintain relaxation under unstimulated conditions, whereas in LPA, telokin's function remains undetermined.
Video-based trailer detection and articulation estimation (2013)

Even for experienced drivers handling a roll trailer with a passenger car is a difficult and often tedious task. Moreover, the driver needs to keep track of the trailer's driving stability on unsteady roads. There are driver assistance systems that can simplify trajectory planning and observe the oscillation amplitude, but they require additional hardware. In this paper, we present a method for trailer detection and articulation angle measurement based on video data from a rear end wide-angle camera. It consists of two stages: to decide whether or not a trailer is coupled to the vehicle and to estimate its articulation angle. These calculations work on single video frames. The vehicle is therefore not required to be in motion. However, we stabilize the single frame estimations by temporal integration. We perform training and parameter optimization and evaluate the accuracy of our approach by comparing the results to those of an articulation measurement unit attached to a test vehicle's hitch. Results show that it can very reliably be determined whether or not a trailer is coupled to the vehicle. Furthermore, its articulation can be estimated with a mean error of less than two degrees.
Identification, Characterization, and Precise Mapping of a Human Gene Encoding a Novel Membrane-Spanning Protein from the 22q11 Region Deleted in Velo–Cardio–Facial Syndrome (1997)

Velo-cardio-facial syndrome (VCFS) and DiGeorge syndrome (DGS) are characterized by a wide spectrum of phenotypes including cleft palate, conotruncal heart defects, and facial dysmorphology. Hemizygosity for a portion of chromosome 22q11 has been detected in 80-85% of VCFS/DGS patients. Using a cDNA selection protocol, we have identified a new gene, TMVCF (transmembrane protein deleted in VCFS), which maps to the deleted interval. The genomic locus is positioned between polymorphic markers D22S944 and D22S941. TMVCF encodes a small protein of 219 amino acids that is predicted to contain two membrane-spanning domains. TMVCF is expressed abundantly in human adult lung, heart, and skeletal muscle, and transcripts can be detected at least as early as Day 9 of mouse development.
Efficacy and Safety of Axitinib in Patients With Advanced Non–Small-Cell Lung Cancer: Results From a Phase II Study (2009)

Capped RNA Transcripts of Full-Length cDNA Clones of Swine Hepatitis E Virus Are Replication Competent When Transfected into Huh7 Cells and Infectious When Intrahepatically Inoculated into Pigs (2005)

Swine hepatitis E virus (swine HEV), the first animal strain of HEV to be isolated, is a zoonotic agent. We report here the construction and in vitro and in vivo characterizations of infectious cDNA clones of swine HEV. Eight overlapping fragments spanning the entire genome were amplified by reverse transcription-PCR and assembled into a full-length cDNA clone, clone C, which contained 14 mutations compared to the consensus sequence of swine HEV. RNA transcripts from clone C were not infectious, as determined by intrahepatic inoculation into pigs and by in vitro transfection of Huh7 cells. Multiple site-based site-directed mutagenesis was performed to generate three new cDNA clones (pSHEV-1, pSHEV-2, and pSHEV-3) which differed from each other. The transfection of capped RNA transcripts into human liver Huh7 cells resulted in the synthesis of both ORF2 capsid and ORF3 proteins, indicating that the cDNA clones were replication competent. Each of the three clones resulted in active swine HEV infections after the intrahepatic inoculation of pigs with capped RNA transcripts. The patterns of seroconversion, viremia, and fecal virus shedding for pigs inoculated with RNA transcripts from clones pSHEV-2 and pSHEV-3 were similar to each other and to those for pigs inoculated with wild-type swine HEV, suggesting that the nucleotide differences between these two cDNA clones were not critical for replication. Pigs inoculated with RNA transcripts from clone pSHEV-1, which contained three nonsilent mutations in the ORF2 capsid gene, had a delayed appearance of seroconversion and fecal virus shedding and had undetectable viremia. The availability of these infectious cDNA clones affords us an opportunity to understand the mechanisms of cross-species infection by constructing chimeric human and swine HEVs.
SVM Kernels for Time Series Analysis (2001)

Time series analysis is an important and complex problem in machine learning and statistics. Real-world applications can consist of very large and high dimensional time series data. Support Vector Machines (SVMs) are a popular tool for the analysis of such data sets. This paper presents some SVM kernel functions and disusses their relative merits, depending on the type of data that is used.

Learning Overcomplete Representations (2000)

In an overcomplete basis, the number of basis vectors is greater than the dimensionality of the input, and the representation of an input is not a unique combination of basis vectors. Overcomplete representations have been advocated because they have greater robustness in the presence of noise, can be sparser, and can have greater flexibility in matching structure in the data. Overcomplete codes have also been proposed as a model of some of the response properties of neurons in primary visual cortex. Previous work has focused on finding the best representation of a signal using a fixed overcomplete basis (or dictionary). We present an algorithm for learning an overcomplete basis by viewing it as probabilistic model of the observed data. We show that overcomplete bases can yield a better approximation of the underlying statistical distribution of the data and can thus lead to greater coding efficiency. This can be viewed as a generalization of the technique of independent component analysis and provides a method for Bayesian reconstruction of signals in the presence of noise and for blind source separation when there are more sources than mixtures.
Thermodynamic and kinetic processes involved in the growth of epitaxial GaN thin films (1993)

Our experimental results using reactive magnetron sputtering, combined with earlier literature, are used to understand the thermodynamic and kinetic processes involved in GaN film growth and the limiting factors involved in the incorporation of nitrogen during the growth process. We show that GaN films fabricated with low pressure growth techniques (&lt;0.1 Torr) such as sputtering and molecular beam epitaxy are formed under metastable conditions with a nonequilibrium kinetically limited reaction. For these methods, the growth process is controlled by a competition between the forward reaction, which depends on the arrival of activated nitrogen species at the growing surface, and the reverse reaction whose rate is limited by the unusually large kinetic barrier of decomposition of GaN. In practice, the thermally activated rate of decomposition sets an upper bound to the growth temperature.
In vivo persistence of adoptively transferred TCR gene-transduced lymphocytes with anti-tumor reactivity in patients with MAGE-A4 expressing esophageal cancer (2013)

Meeting abstracts The application of adoptive immunotherapy with tumor-specific T cells has been limited because of the short life span of the transferred T cells unless the host has been manipulated. Engineering the antigen receptor gene in patients’ lymphocytes is one promising strategy to
Breakdown of a Gas at Microwave Frequencies (1948)

An electric field of sufficiently high frequency applied to electrons in a gas may deliver energy to the electrons without imparting to them any continuous drift motion resulting from the field. The criterion for breakdown of a low pressure gas at microwave frequencies is therefore that ionization by collision of electrons with neutral gas molecules replace loss by diffusion to the walls of the discharge tube. The condition is mathematically expressed as a simple boundary value problem. This breakdown principle is applied to converting microwave breakdown measurements into measurements of ionization rates as a function of the electric field strength, pressure, and frequency. A new ionization coefficient is introduced appropriate to the high frequency discharge conditions, and its relation to the d.c. Townsend coefficient is explained. The energy transfer from the electric field to the electrons at a given $\frac{E}{p}$ is shown to be most efficient when the pressure is high enough or the frequency low enough to result in many collisions of electrons with gas molecules per cycle. This maximum efficiency is equal to the d.c. energy transfer efficiency. When the pressure is lower or the frequency is higher, the electrons have an out-of-phase component of motion and do not receive energy so efficiently, resulting in lower ionization rates observed experimentally.
Quantum nondemolition measurements: the route from toys to tools (1996)

The history of the theory of quantum nondemolition (QND) measurements from the 1920s until today is reviewed. The definition and main principles of QND measurements are outlined. Achievements in the experimental realization of QND measurements and several new promising schemes of QND measurements are described. A list of the most important problems (from the authors' point of view) in the area of QND measurements is presented. The problem of measurement of a quantum oscillator phase is considered. A new method of phase measurement is proposed. Examples of possible solutions of fundamental physical problems using QND methods are given.
An improved bit-flipping scheme to achieve run length control in coded systems (2005)

We propose an improved bit-flipping scheme that combines error-correcting codes such as low-density parity check codes with run length limit (RLL) constraints. In addition to its compatibility with soft decision decoding, the proposed scheme has the advantages of no error propagation and fixed block length. Testing with simulated data and real data show good performance. The loss in performance due to the introduction of RLL constraint is less than 0.1 dB at bit-error rate 10/sup -6/ and block-error rate 10/sup -4/.
