Exception Handling and Recovery of Semantic Web Services (2008)

Abstract In this paper we present an approach for specification of exception handling and recovery of semantic web services based on OWL-S. We use standard fault handlers and compensation known for example from WS-BPEL to provide support for long running transactions. In addition to that, we introduce constraint violation handlers (CV-handlers) which allow a designer to define what situations are supposed to trigger an erroneous state and what are the appropriate recovery actions. Further, we introduce explicit recovery actions such as retry and replaceBy to recover from the failure and to restore a normal execution flow. By combining fault handlers, CV-handlers and standard event handlers it is possible to define ways of recovery for standard errors and for violations of constraints resulting for example from Service Level Agreements (SLAs).
Lifetime of excess electron–hole pairs measured with white noise performance of the photocurrent (2000)

A modified method to measure the lifetime of the excess electron–hole pairs generated by laser beams is proposed. Under the applied bias, excess carriers pass through the sample within the transit time and form the photocurrent Ip. The related white-noise component of the photocurrent can be written as 4egIp, where g is the ratio of the lifetime over the transit time. The lifetime can then be obtained by determining g from the white noise performance. Since the transit time can be adjusted with the applied biases and the sample length, the measured lifetime may be as small as 100 ns with the measurement system even having the analytic frequency range of 10 kHz only. A GaAs sample grown by molecular beam epitaxy is taken as an example to measure the excess carrier’s lifetime. It is concluded from the experiments that the lifetime of excess carriers in our sample is primarily caused by the indirect recombination via the deep trap centers within the band gap. The nonradiative lifetime is not really a constant and its variation versus the laser intensity indeed follows the prediction of the Shockley–Read–Hall recombination theory. This confirms the accuracy of our measurement.
17O relaxation times in the rat brain at 16.4 tesla (2015)

Relaxation times of brain H2 (17) O were measured for the first time in vivo in different types of tissues with high spatial resolution. Because the relaxation times of H2 (17) O are expected to be independent of field strength, our results should help in optimizing the acquisition parameters for experiments also at other MRI field strengths.
Antioxidant treatment for heart failure: friend or foe? (2008)

Increasing studies demonstrate a pivotal role for oxidant stress in the pathophysiology of heart failure (HF). Recent meta-analyses also reveal the potential pitfall of a mono-dimensional antioxidant approach. This review article summarizes the main biological pathways involved in oxidant stress and HF, the possible deleterious nature of certain antioxidant monotherapy and proposes potential antioxidant strategies necessary to challenge specific HF aetiology and progression.
Usability Benefits and Challenges in mmWave V2V Communications: A Case Study (2019)

Recently, an active discussion on the feasibility of Millimeter Wave (mmWave) frequencies for the Vehicle-to-Vehicle (V2V) communication have been carried out in research community. We contribute to this discussion by providing a comparison between explicit three-dimensional ray-tracing simulations and field trial measurements on 39 GHz frequency. Three basic practical and relevant cases for V2V communications are considered covering several important scenarios of daily life traffic. A close match between the measured and simulated results is found through explicit ray tracing simulations; thus validating the feasibility of the simulation model and underlying assumptions. Moreover, these outcomes also shed light on the potential and challenges of using mmWave frequencies for V2V communication. The acquired results indicate that the Reference Signal Received Power (RSRP) levels are sufficiently above the noise level even up to 100 m distance between TX and RX in case of a single obstructing car. Results also reveal the impact of moving vehicle intersecting the LOS between the TX and RX vehicle at road intersection, and they indicate a notable blockage loss in case of short TX-RX separation.
Abstract 15463: Occupational Health Hazards of Working in the Interventional Laboratory: A Large Case-Control Study (2014)

Introduction: An increase in PCI volumes, complexity, and procedure times has led to both an increase in physical stresses related to wearing protective lead aprons and operator radiation exposure. The effects of such occupational hazards remain poorly understood as available studies have limitations such as poor survey response rates, lack of age-matched controls, and subjective pain assessment.

Methods: We surveyed 1541 Mayo Foundation employees within the departments of cardiology and radiology (1042 without and 499 with radiation exposure) for pain, cancer, thyroid disease, cataract, and nephrolithiasis and stratified them based on their exposure to radiation. Multiple logistic regression was used to estimate adjusted associations between radiation exposure and endpoints.

Results: The response rate was 57%. The average age was 43 years; 33% were male. The associations between pain and medical diagnoses with radiation exposure are summarized in the Table.

Conclusions: In personnel exposed to radiation working in laboratories, there is a higher prevalence of musculoskeletal pain but the prevalence of cancer, cataract, thyroid problems and nephrolithiasis are similar. There was a trend towards a higher incidence of composite endpoints. Larger studies are needed to confirm this association.

Generation of twenty four induced pluripotent stem cell lines from twenty four members of the Lothian Birth Cohort 1936 (2020)

Abstract Cognitive decline is among the most feared aspects of ageing. We have generated induced pluripotent stem cells (iPSCs) from 24 people from the Lothian Birth Cohort 1936, whose cognitive ability was tested in childhood and in older age. Peripheral blood mononuclear cells (PBMCs) were reprogrammed using non-integrating oriP/EBNA1 backbone plasmids expressing six iPSC reprogramming factors (OCT3/4 (POU5F1), SOX2, KLF4, L-Myc, shp53, Lin28, SV40LT). All lines demonstrated STR matched karyotype and pluripotency was validated by multiple methods. These iPSC lines are a valuable resource to study molecular mechanisms underlying individual differences in cognitive ageing and resilience to age-related neurodegenerative diseases.
Effect of hydrogen on propene polymerization with solvay‐type TiCl3/Cp2 TiMe2 catalyst (1989)

Abstract Polymerization of propene with a highly isospecific Solvay‐type TiCl 3 /Cp 2 TiMe 2 catalyst in the presence and absence of hydrogen was investigated. It was found that hydrogen exerts almost no effect on the molecular weight and the stereoregularity of the resulting polypropylene. Furthermore, the H 2 /D 2 exchange reaction hardly proceeds over the catalyst. To discuss this unusual behavior, plausible mechanistic explanations on the basis of the structure of active species are proposed.
Longitudinally Tracking Maternal Autonomic Modulation During Normal Pregnancy With Comprehensive Heart Rate Variability Analyses (2022)

Changes in the maternal autonomic nervous system are essential in facilitating the physiological changes that pregnancy necessitates. Insufficient autonomic adaptation is linked to complications such as hypertensive diseases of pregnancy. Consequently, tracking autonomic modulation during progressing pregnancy could allow for the early detection of emerging deteriorations in maternal health. Autonomic modulation can be longitudinally and unobtrusively monitored by assessing heart rate variability (HRV). Yet, changes in maternal HRV (mHRV) throughout pregnancy remain poorly understood. In previous studies, mHRV is typically assessed only once per trimester with standard HRV features. However, since gestational changes are complex and dynamic, assessing mHRV comprehensively and more frequently may better showcase the changing autonomic modulation over pregnancy. Subsequently, we longitudinally (median sessions = 8) assess mHRV in 29 healthy pregnancies with features that assess sympathetic and parasympathetic activity, as well as heart rate (HR) complexity, HR responsiveness and HR fragmentation. We find that vagal activity, HR complexity, HR responsiveness, and HR fragmentation significantly decrease. Their associated effect sizes are small, suggesting that the increasing demands of advancing gestation are well tolerated. Furthermore, we find a notable change in autonomic activity during the transition from the second to third trimester, highlighting the dynamic nature of changes in pregnancy. Lastly, while we saw the expected rise in mean HR with gestational age, we also observed increased autonomic deceleration activity, seemingly to counter this rising mean HR. These results are an important step towards gaining insights into gestational physiology as well as tracking maternal health via mHRV.
Progress of Gas-Filled Multi-RF-Cavity Beam Profile Monitor for Intense Neutrino Beams (2017)

A novel pressurized gas-filled multi-RF-cavity beam profile monitor has been studied that is simple and robust in high-radiation environments. Charged particles passing through each RF-cavity in the monitor produce intensity-dependent ionized plasma, which changes the gas permittivity. The sensitivity to beam intensity is adjustable using gas pressure and RF gradient. The performance of the gas-filled beam profile monitor has been numerically simulated to evaluate the sensitivity of permittivity measurements. The result indicates that the RF resonator will be useful to measure the beam profile with a charged beam intensity range from 10⁶ to 10¹³ protons/bunch. The range covers the expected beam intensities in NuMI and LBNF. The demonstration of the monitor with intense proton beams are taken place at Fermilab to validate the simulation result. The result will be given in this presentation.
Fast multiplane functional imaging combining acousto-optic switching and remote focusing (2017)

Networks of neurons are inherently three-dimensional in nature, whereas conventional imaging methods, such as laser scanning two-photon microscopy, usually provide only fast two-dimensional imaging. Rapid volumetric imaging would however be preferable for imaging neurons. To get a more complete picture of the dynamics of the neuron-to-neuron interactions, we have developed a pseudo-parallelised multi-plane two-photon excitation imaging system through the incorporation of an acousto-optic switching and a remote focusing technique into a resonant scanning microscope. This permits the recording of millisecond scale fluorescence transients of calcium indicators from large populations of neurons upon neural firing events at multiple chosen axial planes in very short time frame. While the remote focusing system offers aberration-free axial scanning over a few hundreds of micrometres of depth, the acousto-optic deflector provides high speed optical switching between different laser beam paths in sub-microsecond timescale which in turn, controls the axial focal plane to be targeted. Here, we report on the development of the high temporal resolution multi-plane targeted microscope and its potential application.
Integration of Ball Lens in Through-Package Via to Enable Photonic Chip-to-Board Coupling (2018)

Optical interconnects offer a promising solution to achieve a larger bandwidth distance product, interconnect density and power efficiency compared to their electrical counterparts. The development of a highly efficient and compact interface between CMOS-compatible silicon photonics and board-level optical interconnects can provide a solution to overcome bandwidth-power limitation across chip-to-chip short-reach interconnections for future data centers. In this context, a method to integrate a silicon photonic chip, ball lens embedded package substrate and board-level polymer multimode waveguides has been demonstrated. The development of the involved optical interfaces and corresponding measurement results are reported aided by simulation results. A key outcome of the experiment was a measured 14 micrometre chip-to-package 1dB lateral alignment tolerance for coupling into a 20x24 micrometres squared cross-section board-level polymer multimode waveguide. A 3.4 dB coupling loss across the optical interfaces between the photonic chip output grating and polymer waveguide was measured at a wavelength of 1310 nm.
Determination of Surface Chemical Species in GaAs Atomic Layer Epitaxy by In Situ Gravimetric Monitoring (1994)

Atomic layer epitaxy (ALE) using a GaCl source is investigated by a real-time in situ gravimetric monitoring method. An ALE system with an electrobalance is used as a monitoring system. The direct gravimetric information from the growing surface in the growth system of ALE is monitored during an ALE cycle. It is shown that the surface chemical species are one-monolayer Ga atoms during H 2 purge after GaCl supply, and the in situ gravimetric method is a powerful tool for the investigation of the ALE growth mechanism.
Control adaptation approach for fault detection and isolation in SIDI high pressure fuel pump (2017)

Spark Ignition Direct Injection (SIDI) technology enables better fuel economy and tail pipe emissions in vehicles equipped with gasoline engines. The SIDI technology relies on the system's ability to deliver fuel at high pressures and reliable performance of the high pressure fuel pump is vital as it directly relates to the operability of the vehicle. It, therefore, becomes very important to devise a scheme that can effectively diagnose and prognose faults of such a component. In this article, algorithm development for incipient fault detection, and isolation of high pressure fuel pump faults is presented. In particular, the control adaptation of the high pressure fuel pump is employed to generate schemes for fault detection, and fault isolation. Results from simulations as well as real vehicle test data are presented to depict various fault behaviors and their manifestations. The learnings thus obtained enabled the design of fault detection, and isolation scheme for high pressure fuel pump and allows monitoring of health as the faults grow.
Role of TWEAK/Fn14 in chronic inflammatory disorders of the skin (2016)

Abstract Atopic dermatitis and Psoriasis are inflammatory disorders of the skin. Despite particular differences in respect of etiology, pathogenesis and clinical manifestations, these diseases share histological features such as epidermal hyperplasia and dermal fibrosis. Discovering molecules that contribute to the development of both diseases could provide opportunities for therapeutic intervention. It is accepted that keratinocytes and dermal fibroblasts play a pivotal role in both diseases by amplifying and maintaining inflammatory and fibrotic responses. TNF superfamily members, including TWEAK (TNFSF12), have been implicated in control of these cell types, but experimental insights are scarce. Employing TWEAK-deficient mice, we demonstrated that the TWEAK/Fn14 axis is indispensable for experimental atopic dermatitis and psoriasis. Furthermore, we found that subcutaneous injection of recombinant TWEAK into naïve mice is sufficient to induce robust inflammation with histological and molecular signatures of both atopic dermatitis and psoriasis. Moreover, in vitro experiments revealed that keratinocytes and dermal fibroblasts produced key chemokines and cytokines in response to TWEAK that are characteristic of both atopic dermatitis and psoriasis, and these molecules were amplified when TWEAK was combined with the signature cytokines IL-13 and IL-17. Similarly, subcutaneous injection of TWEAK with IL-13 or IL-17 synergized with respect to infiltration and intra cutaneous expression of proinflammatory molecules. These studies help to understand the network of factors active in the pathogenesis of skin inflammatory disorders, and highlight TWEAK as a central regulator of both atopic dermatitis and psoriasis.
Temporal and mechanistic dissociation of ATP and adenosine release during ischaemia in the mammalian hippocampus1 (2007)

Adenosine is well known to be released during cerebral metabolic stress and is believed to be neuroprotective. ATP release under similar circumstances has been much less studied. We have now used biosensors to measure and compare in real time the release of ATP and adenosine during in vitro ischaemia in hippocampal slices. ATP release only occurred following the anoxic depolarisation, whereas adenosine release was apparent almost immediately after the onset of ischaemia. ATP release required extracellular Ca2+. By contrast adenosine release was enhanced by removal of extracellular Ca2+, whilst TTX had no effect on either ATP release or adenosine release. Blockade of ionotropic glutamate receptors substantially enhanced ATP release, but had only a modest effect on adenosine release. Carbenoxolone, an inhibitor of gap junction hemichannels, also greatly enhanced ischaemic ATP release, but had little effect on adenosine release. The ecto-ATPase inhibitor ARL 67156, whilst modestly enhancing the ATP signal detected during ischaemia, had no effect on adenosine release. Adenosine release during ischaemia was reduced by pretreatment with homosysteine thiolactone suggesting an intracellular origin. Adenosine transport inhibitors did not inhibit adenosine release, but instead they caused a twofold increase of release. Our data suggest that ATP and adenosine release during ischaemia are for the most part independent processes with distinct underlying mechanisms. These two purines will consequently confer temporally distinct influences on neuronal and glial function in the ischaemic brain.
Comparative analysis of mycobacterium and related actinomycetes yields insight into the evolution of mycobacterium tuberculosis pathogenesis (2012)

Our analysis of protein evolution highlights gene families that are associated with the adaptation of environmental Mycobacteria to obligate pathogenesis. These families include fatty acid metabolism, DNA repair, and molybdopterin biosynthesis. Our analysis reinforces recent findings suggesting that small noncoding RNAs are more common in Mycobacteria than previously expected. Our data provide a foundation for understanding the genome and biology of Mtb in a comparative context, and are available online and through TBDB.org.
New Tone Reservation Technique for Peak to Average Power Ratio Reduction (2014)

Abstract In Orthogonal Frequency Division Multiplexing (OFDM) the transmit signals have a highly fluctuating, non-constant envelope which is a technical challenge for the High Power Amplifier (HPA). Without any signal processing procedures the amplitude peaks of the transmit signal will be clipped by the HPA resulting in out-ofband radiation and in bit error rate (BER) performance degradation. The classical Tone Reservation (TR) technique calculates a correction signal in an iterative way to reduce the amplitude peaks. However this step leads to a high computational complexity. Therefore, in this paper an alternative TR technique is proposed. In this case a predefined signal pattern is shifted to any peak position inside the transmit signal and reduces thereby all amplitude peaks. This new procedure is able to outperform the classical TR technique and has a much lower computational complexity.
Differentiation of the Nucleotide Pyrophosphatases of Rat‐Liver Plasma Membrane and Endoplasmic Reticulum by Enzymic Iodination (1976)

Enzymic iodination of isolated rat hepatocytes and of rat livers perfused in situ was used to discriminate between the nucleotide pyrophosphatases of endoplasmic reticulum and of plasma membranes. The location of the latter on the cell surface could also be substantiated by this method. The activity of the microsomal enzyme increased after phenobarbital treatment of the animals. The nucleotide pyrophosphates from both subcellular fractions were solubilized, purified to electrophoretic homogeneity, and their 125I content determined. The labelling of the enzyme obtained from plasma membranes was several-fold higher than that of the nucleotide pyrophosphatase from endoplasmic reticulum. This indicates a bimodal distribution of nucleotide pyrophosphatase in rat liver and the accessibility of the plasma membrane enzyme from the extracellular space.
MQAG: Multiple-choice Question Answering and Generation for Assessing Information Consistency in Summarization (2023)

State-of-the-art summarization systems can generate highly fluent summaries. These summaries, however, may contain factual inconsistencies and/or information not present in the source. Hence, an important component of assessing the quality of summaries is to determine whether there is information consistency between the source and the summary. Existing approaches are typically based on lexical matching or representation-based methods. In this work, we introduce an alternative scheme based on standard information-theoretic measures in which the information present in the source and summary is directly compared. We propose a Multiple-choice Question Answering and Generation framework, MQAG, which approximates the information consistency by computing the expected statistical distance between summary and source answer distributions over automatically generated multiple-choice questions. This approach exploits multiple-choice answer probabilities, as predicted answer distributions can be compared. We conduct experiments on four summary evaluation datasets: QAG-CNNDM/XSum, XSum-Hallucination, Podcast Assessment, and SummEval. Experiments show that MQAG, using models trained on SQuAD or RACE, outperforms existing evaluation methods on the majority of tasks.
