A Unified and Scalable Data Migration Service for the Cloud Environments (2009)

Data migration is one of the key operations in many enterprise data integration projects. While there are standard and well established tools for data migration, the enterprises recent move towards cloud environments present increasing challenges with respect to scalability, availability and data model heterogeneities. In this demo paper, we present a scalable data migration service that employs automated schema matching techniques to handle the schema disparities in cloud and enterprise data models. The proposed system also uses elastic grid infrastructure for on-demand data access, rules driven transformation and on-the-fly integration of distributed data sources for migration. We bring out key research challenges in building such a system and present viable solutions for addressing the same. The demo is likely to be useful for the academicians in getting insights on newer challenges in this field and the practitioners can benefit from understanding new offerings in this space 1.
<title>Evaluation Of Image Processing For Man-In-Loop Target Acquisition</title> (1980)

A major operational need facing the next generation of Scout (ASH) and Attack (AAH) helicopters is to detect targets from nap-of-earth altitudes, on a realistic battlefield in a complex and cluttered scene. The targets of interest here are primarily the single, high threat target which will not be contained with the main body of target tanks and will not present many detection cues. Various image enhancement methods have been evaluated in terms of improved operator performance. Quantitative performance measures such as contrast, resolution and signal-to-noise ratio are computed for selected algorithms and related to observer performance probabilities. This paper presents analysis and simulation results for an image enhancement method known as local area gain control. It shows dependence on parameter selection and develops criteria for evaluation in terms relatable to detection probability.

Multilocus Sequence Typing of Swedish Invasive Group B Streptococcus Isolates Indicates a Neonatally Associated Genetic Lineage and Capsule Switching (2005)

Streptococcus agalactiae, also designated group B streptococcus (GBS), is an important pathogen in neonates, pregnant women, and nonpregnant adults with predisposing conditions. We used multilocus sequence typing (MLST) to characterize 158 GBS isolates that were associated with neonatal and adult invasive disease and that were collected in northern and western Sweden from 1988 to 1997. Five major genetic lineages (sequence type [ST] 19, ST-17, ST-1, ST-23, and ST-9 complexes) were identified among the isolates, including serotype Ia, Ib, and II to V isolates, indicating a highly clonal population structure among invasive GBS isolates. A number of STs were found to contain isolates of different serotypes, which indicates that capsule switching occurred rather frequently. Two distantly related genetic lineages were identified among isolates of serotype III, namely, clonal complex 19 (CC19), and CC17. CC19 was equally common among isolates from adult and neonatal disease (accounting for 10.3% of GBS isolates from adult disease and 18.7% from neonatal disease), whereas CC17 significantly appeared to be associated with neonatal invasive disease (isolated from 21.9% of neonatal isolates but only 2.6% of adult isolates). The distribution of the mobile elements GBSi1 and IS1548 reveals that they can act as genetic markers for lineages CC17 and CC19, respectively.
Body and Consciousness: A Conversation with Antonio Damasio (2000)

This is an interview with neurologist Antonio Damasio, MD, PhD, whose work on consciousness has influenced scholars in a variety of fields, including anthropology. Damasio addresses a number of issues, including the neurobiology of altered states, the neurology of flow and other optimal, pleasurable states, and the potential to identify biological markers that are common to the experience of altered states in a variety of cultures. Damasio also discusses the relationship between body and brain, and concludes by discussing the scope of the consciousness problem and contributions to the solution that anthropologists might be well suited to make. Key words: body, consciousness, altered states, interview.
A cascaded hybrid phase shift-PWM and asymmetric selective harmonic mitigation-PWM modulation technique for grid-tied converter to reduce the switching frequency and meet the grid current harmonic requirement (2017)

In this paper, a low frequency hybrid cascaded phase shift-PWM (PSPWM) and asymmetric selective harmonic mitigation-PWM (ASHM-PWM) modulation technique is proposed to meet limits of power quality standard with the low number of switching frequency. For this aim, the low order harmonics of PSPWM technique are reduced by the ASHM-PWM technique. The equations of both modulation techniques are included in the optimization process to meet standard for all of the low order current harmonics of grid-tied cascaded h-bridge (CHB) converter. The proposed technique has advantages of both PSPWM and ASHM-PWM modulation techniques. Furthermore, the critical parameters of grid-tied CHB converter such as inductance and switching frequency of converter are derived based on the equations of proposed hybrid PSPWM and ASHM-PWM technique. The simulation and experimental results were conducted on 7-level CHB converter to validate the proposed modulation technique.
CRACK-FREE WEAR RESISTANCE COATINGS PRODUCED ON PURE TITANIUM AND <font>Ti-6Al-4V</font> BY LASER NITRIDING (2005)

Cracks-free wear resistance coatings are fabricated by laser surface nitriding pure titanium and Ti-6Al-4V in an open system. The titanium nitrides which are formed in situ in the top layers of the samples are undeveloped dendritic, and thus reduce the possibility of the crack formation in the coatings during laser processing. The test results show that the nitride layers have higher microhardness and more resistant to sliding wear compared to the as-received sample.
Regulation of cholangiocyte bicarbonate secretion (2001)

The objective of this review article is to discuss the role of secretin and its receptor in the regulation of the secretory activity of intrahepatic bile duct epithelial cells (i.e., cholangiocytes). After a brief overview of cholangiocyte functions, we provide an historical background for the role of secretin and its receptor in the regulation of ductal secretion. We review the newly developed experimental in vivo and in vitro tools, which lead to understanding of the mechanisms of secretin regulation of cholangiocyte functions. After a description of the intracellular mechanisms by which secretin stimulates ductal secretion, we discuss the heterogeneous responses of different-sized intrahepatic bile ducts to gastrointestinal hormones. Furthermore, we outline the role of a number of cooperative factors (e.g., nerves, alkaline phosphatase, gastrointestinal hormones, neuropeptides, and bile acids) in the regulation of secretin-stimulated ductal secretion. Finally, we discuss other factors that may also play an important role in the regulation of secretin-stimulated ductal secretion.
Analysis of the basal and inducible activities of the ICPO promoter of herpes simplex virus type 1. (1998)

Sequences from -420 to -70 from the ICPO transcriptional start site of herpes simplex virus type 1 are dispensable for reactivation from latency. A putative cAMP-response element (CRE) outside of this region was non-functional in both murine neuroblastoma (NB41A3) and rat pheochromocytoma (PC12) cells. Also, poor binding of cAMP-response element binding protein (CREB) was observed. Sequences from -95 to -37 are important for constitutive activity in NB41A3, PC12 and baby hamster kidney (BHK) cells. The TATA box and Sp1 site were also shown to be major contributors to constitutive activity. Finally, high constitutive activity of a deleted construct (-420 to -1) in NB41A3 and BHK cells suggests transcription initiates upstream of -420 in the absence of VP16. The implications of these observations regarding ICPO expression during the virus life-cycle are discussed.
Fabrication of a single-electron inverter in multiwall carbon nanotubes (2003)

A single-electron inverter based on the Coulomb blockade effects has been fabricated in multiwalled carbon nanotubes, by using the Ar irradiation method for the tunnel barrier formation in the quantum dots. The device characteristics were measured at 2.6 K, and an indication of inverter-like transfer characteristics has been obtained. The performance of the device was not completely satisfactory for the inverter operation in terms of the voltage gain and the voltage swing, but the present technique turns out to be useful for the fabrication of single-electron logic devices in carbon nanotubes.
Time-resolved thermal mirror for nanoscale surface displacement detection in low absorbing solids (2007)

A time-resolved thermal mirror method for measurements of absolute thermo-optical-mechanical properties of low absorbing solids is presented. The thermoelastic equation for the surface displacement and an analytical expression for the probe beam intensity at the detector plane were derived. Experimental proofs were performed in an optical glass and the fitted parameters are in good agreement with previous literature data for thermal, optical, and mechanical properties, suggesting that the method is a useful tool for the characterization of a wide range of transparent materials.
Using Dynamic Simulation in the Development of Construction Machinery (2003)

As in the car industry for quite some time, dynamic simulation of complete vehicles is being practiced more and more in the development of off-road machinery. However, specific questions arise due not only to company structure and size, but especially to the type of product. Tightly coupled, non-linear subsystems of different domains make prediction and optimisation of the complete system's dynamic behaviour a challenge. Furthermore, the demand for versatile machines leads to sometimes contradictory target requirements and can turn the design process into a hunt for the least painful compromise. This can be avoided by profound system knowledge, assisted by simulation-driven product development. This paper gives an overview of joint research into this issue by Volvo Wheel Loaders and Linkoping University on that matter, lists the results of a related literature review and introduces the term "operateability". Rather than giving detailed answers, the problem space for ongoing and future research is examined and possible solutions are sketched.
The Functioning of the Giant Nerve Fibres of the Squid1 (1938)

ABSTRACT Stimulation of single giant nerve fibres in the stellar nerves of the squid (Loligo pealii) shows them to be motor axons which produce contraction of the circular fibres of the mantle muscles. When a stellar nerve is stimulated with condenser discharges a maximal response is obtained at threshold voltage. No increase of response is obtained by further increase in the strength of stimulation except for an occasional slight increase at about ten times threshold voltage probably due to repetitive firing. It therefore appears that the stimulus produces a single impulse in the giant fibre, and that this is capable of exciting contraction in all the muscle fibres which it reaches. This confirms the conclusion reached on histological grounds that in spite of their syncytial nature each of the giant nerve fibres is a single functional unit. Since there are about ten giant fibres on each side the mantle is divided into 20 neuromotor units, each nerve fibre innervating an enormous number of muscle fibres. The existence of these units can also very readily be demonstrated by the fact that threshold electrical stimulation at any point within the territory innervated by each single giant fibre sets up a contraction of the muscle fibres of all parts of the territory with which the stimulated area is in connexion through the nerve. Stimulation of the smaller fibres in a stellar nerve after destruction of the giant fibre also causes contraction of the circular muscles of the mantle. The amount of this contraction increases progressively with increased voltage, presumably on account of the stimulation of more and more nerve fibres. The maximum tension developed in this way is always very much less than that produced by stimulation of the giant fibres. The mantle is therefore provided with a double mechanism of expiratory contraction, maximal contractions being produced by single impulses in the giant fibres and graded contractions by those in the smaller fibres of the nerve. Presumably the former contractions are those involved in rapid movement, the latter in respiration. There are also radial muscles, running through the thickness of the mantle, whose contractions effect the inspiration by making the cavity larger.
The Influence of Unlined Boreholes on Groundwater Chemistry: A Comparative Study Using Pore‐Water Extraction and Packer Sampling (1993)

Abstract In the consolidated formations which form most of the major aquifers in the UK, many monitoring boreholes are left unlined (open) for their effective length. They therefore provide pathways for groundwater to flow from one part of the aquifer to another. A borehole was core‐drilled through Triassic sandstones into Permian mudstones at a site in North Yorkshire. Pore water was extracted from the core and compared with conventional depth samples and with samples taken from intervals isolated using packer systems: (a) during drilling, (b) about one month after drilling, and (c) two years after drilling. The study revealed that natural flow down the borehole led to rapid changes in the quality of water in some parts of the formation. The implication is that open boreholes can act as conduits to allow flow to take place from one part of the aquifer to another. They are therefore not reliable as sampling points, and may actually accelerate the vertical spread of pollutants. However, this last effect should not be over‐stated; in this study, the flow down the borehole was equivalent to the natural flow through only a relatively small area of land.
INVESTIGATIVE STUDY OF HEAT TRANSFER AND BLADES COOLING IN THE GAS TURBINE (2005)

Flow visualization experiments had been conducted using a water tunnel to investigate and study the effect of different hole geometries on lift-off and spreading characteristics on a jet in a cross flow stream. The relationships between the hydraulic diameters of the hole geometries and their lift-off and spreading characteristics were also investigated. Eight different hole geometries with the same cross-sectional area were used in the experiments. They are round, square, triangle, rectangular, "rect-circle", "peanut", "V-shaped" and "W-shaped". Dye release injection technique was used to visualize the characteristics of the jet trajectories from different hole geometries. From the results, the different geometries of cooling holes were found to have an effect on the trajectory of the jet. Hole geometries with "tongues" in them such as "W-shaped" and "V-shaped" holes produced jets with better flow adherence but poorer spreading. Hole geometries with lower hydraulic diameters also produced jets with better flow adherence but poorer spreading.
Absolute interferometric distance measurement using a FM-demodulation technique (1995)

We propose an interferometric method for measuring absolute distances larger than the wavelength. A laser diode is used as a light source. The principle of operation is based on multiple-wavelength interferometry that uses a modulated light source. This method uses the fact that the wavelength of light emitted by the laser diode can be varied by means of the injection current. The modulation of the injection current in combination with the optical heterodyne technique causes a high-frequency phase-modulated detector signal. The phase deviation of the signal is a measure of the optical path difference in the interferometer. By FM demodulation of the detector output with a phase-locked loop demodulator, the optical path difference can be determined directly without the classical ambiguity problem of interferometry. The measuring range in the experiments was limited to 50 mm by the maximum travel range of the used specimen translation stage. Because of the inherent light sensitivity of the method described, the rangefinder can be used for three-dimensional profile measurements on a wide variety of objects, even on diffuse scattering surfaces.
Long-term inhibition of NO synthesis promotes atherosclerosis in the hypercholesterolemic rabbit thoracic aorta. PGH2 does not contribute to impaired endothelium-dependent relaxation. (1994)

We examined whether prostaglandin (PG) H2, as an endothelium-dependent contracting factor, or the disturbed production of endothelium-derived relaxing factor, impairs endothelium-dependent relaxation and whether long-term inhibition of nitric oxide (NO) synthesis aggravates atherosclerosis in hypercholesterolemic rabbits. Male New Zealand White rabbits were fed one of the following diets: (1) standard chow; (2) 2% cholesterol-supplemented chow; (3) standard chow with 80 micrograms/mL N omega-nitro-L-arginine methylester (L-NAME), an NO synthetase inhibitor, in their drinking water; or (4) 2% cholesterol-supplemented chow with 80 or 160 micrograms/mL L-NAME in their drinking water. The rabbits were fed these diets for 8 or 12 weeks. Then aortic rings were obtained, and changes in isometric tension were recorded. Intimal atherosclerotic areas of the thoracic aortas were subsequently measured by planimetry. The cholesterol-supplemented diet significantly impaired endothelium-dependent aortic relaxation to acetylcholine. Pretreatment with the thromboxane A2/PGH2 receptor antagonist ONO-3708 did not reverse this impaired response. Vessels from both normocholesterolemic and hypercholesterolemic rabbits given L-NAME showed more impaired endothelium-dependent relaxation than those from their dietary counterparts not given L-NAME. Morphometric analysis revealed marked enlargement of intimal atherosclerotic areas in aortas from L-NAME-treated hypercholesterolemic rabbits compared with those from untreated hypercholesterolemic rabbits. These findings suggest that PGH2 does not contribute to impaired endothelium-dependent relaxation and that long-term administration of L-NAME promotes atherosclerosis by inhibition of NO synthesis in the hypercholesterolemic rabbit thoracic aorta.
Preparation and characterization of Fe-incorporated titanate nanotubes (2006)

A simple hydrothermal procedure is developed for incorporating Fe into H2Ti3O7 nanotubes. Detailed characterizations have been carried out using scanning electron microscopy, transmission electron microscopy, energy dispersive x-ray spectroscopy, electron energy loss spectroscopy and x-ray diffractometry, and results showed that the specimens have the same structural framework as H2Ti3O7, into which Fe atoms are successfully incorporated. Ultraviolet–visible absorption spectra show that the Fe-incorporated H2Ti3O7 nanotube has a much improved photon absorption efficiency in the visible region compared with the pure H2Ti3O7 nanotube. Other metals have also been incorporated into H2Ti3O7 nanotubes, and similar improvements are observed in some of these metal-incorporated nanotubes.
Robust IP and UDP-lite header recovery for packetized multimedia transmission (2010)

Recently, Joint Source-Channel Decoding (JSCD) techniques have been proposed to improve the reception of multimedia contents transmitted over error-prone channels. These techniques take advantage of the redundancy left by the source coder and of bit reliability measures (soft information) provided by channel decoders to correct transmission errors. To be put at work, protocol stacks have to be made permeable to transmission errors in order to allow soft information to reach the upper protocol layers. For that purpose, headers have to be reliably estimated at each protocol layer. First results have been obtained for lower protocol layers (PHY and MAC) protected by CRCs. The aim of this paper is to extend these results to upper protocol layers (IP and UDP-lite) protected by checksums. As for CRCs, trellis-based decoding techniques may be employed for data protected by checksums. Nevertheless, specific tools have been proposed in this paper to reach a complexity-efficiency trade-off.

Reducing GPS Wide Lane Ambiguity Resolution Time: A Novel Carrier Phase Multipath Mitigation Technique (2013)

Modeling and mitigating carrier multipath errors continues to be a significant challenge for high accuracy positioning using Global Navigation Satellite Systems (GNSS), because the level of multipath is dependent on the operational environment and cannot be mitigated by differencing techniques. Despite significant research in the domain, multipath remains a major problem in high accuracy positioning. The effect of carrier multipath is even more significant when observables are formed by linear combination of measurements from two or more frequencies. Yet, such combinations are commonly in use. For example, in order to facilitate ambiguity fixing for GPS L1, the wide lane observable formed from GPS L1 and L2 measurements is often used to constrain the L1 ambiguity space. Multipath error causes a bias in the estimation of the float solution making it difficult to resolve the integer ambiguities. In this paper, a novel method is developed to mitigate carrier multipath errors for linear combinations, focusing on the wide lane observable. This consists in two stages. In the first stage an observable is derived from combined use of measurements in the same and different frequencies (i.e. GPS L1 and L2), and in the second the observable is applied to mitigate wide lane carrier multipath errors. The proposed method reduces the carrier multipath error in wide lane observables to the level of carrier multipath in the L1 observable, which is significantly smaller. Three test scenarios with different baselines were conducted using real data sets collected in static mode, and post processed in Real-Time Kinematic (RTK) mode. After applying the multipath mitigation method, the time duration to ambiguity resolution were reduced by 25, 48 and 129 seconds, compared to 47, 535 and 427 without the proposed method, for different test scenarios. It means about 53% improvement was achieved in scenario 1, 9% in scenario 2 and 30% in scenario 3. Keywords— linear combination; Inter Frequency Multipath; integer ambiguity resolution; wide lane
Administration of Endocannabinoids Prevents a Referred Hyperalgesia Associated with Inflammation of the Urinary Bladder (2001)

Anandamide (via CB1 receptors) and palmitoylethanolamide (putatively via CB2 receptors) attenuated a referred hyperalgesia in a dose-dependent fashion. CB1 and CB2 receptors are strategically situated to influence the nerve growth factor-driven referred hyperalgesia associated with inflammation of the urinary bladder. These data implicate cannabinoids as a novel treatment for vesical pain.
