Distributed constraint optimization for autonomous multi AUV mine counter-measures (2018)

In this paper, Mine Counter-Measures (MCM) operations with multiple cooperative Autonomous Underwater Vehicles (AUVs) are examined within the Distributed Constraint optimization Problem (DCOP) framework. The goal of an MCM-operation is to search for mines and mine-like objects within a predetermined area so that ships can pass the area through a safe transit corridor. Performance metrics, such as the expected time of completion and the level of confidence that all mine-like objects within the area have been detected, are used to quantity the utility of the operation. The AUVs coordinate their individual search segments in a distributed manner in order to maximize the global utility. The segmentation is optimized by the Compression-DPOP (C-DPOP) algorithm, which allows explicit reasoning by the AUVs about their actions based on the performance metrics. After initial segmentation of the mine threat area, subsequent optimizations are triggered by the AUVs based on the variations in sonar performance. The performance of the C-DPOP algorithm is compared to a static segmentation approach and validated using the high-fidelity Unmanned Underwater Vehicle (UUV) simulation environment based on the Gazebo simulator.
P3–187: Endothelial cell activation and cerebral white matter lesions in an autopsy based study (2006)

White matter lesions (WML) and subcortical atrophy (SCA) are frequently found in healthy elderly and are even more prevalent in patients with dementia. Markers of inflammation are related to their presence, possibly mediated by endothelial dysfunction. However, circulating levels of inflammatory markers may not reflect the actual degree of inflammation in the brain. To investigate the relation between endothelial cell activation in the brain and WML and SCA on neuroimaging. We investigated the brains of 12 consecutive non–demented patients with a recent (<3 months) CT or MRI. Post–mortem biopsies were taken in a standardized way of the right frontal cortex. Frozen sections (5 μm) were stained with antibodies for P–selectin and CD34, a marker for endothelial cell activation and a general marker for endothelium, respectively. The relative proportion of P–selectin positive vessels was measured, in duplo. WML were rated with the age related white matter changes scale. SCA was the mean of the ventricle–to–brain ratio at the the frontal, bicaudate and occipital level. The relation between endothelial cell activation and WML (ARWMC > 0) and severe SCA (dichotomized at the median) was assessed with the Mann–Whitney U test. Mean age was 65.6 years (SD 13.6) and 46% were female. 45% had WML. The proportion of P–selectin positive vessels ranged from 0.8% to 11.1%. Patients with WML had a significantly higher proportion P–selectin positive vessels compared to those without (8.0% (SD 0.9) vs 5.0% (SD 3.7); p=0.01). Patients with severe SCA also had a significantly higher proportion of P–selectin positive vessels compared to those without (8.0% (SD 2.3) vs 4.3% (SD 2.8); p=0.04). Patients with SVD had an increased number of P–selectin positive vessels, possibly reflecting endothelial activation in the brain. This may provide a rationale on how inflammation may relate to vessel wall damage and subsequently may lead, to SVD.

Face alignment under variable illumination (2004)

This paper presents an approach to face alignment under variable illumination, an obstacle largely ignored in previous 2D alignment work. To account for illumination variation, our method employs two forms of relatively lighting-invariant information. Edge phase congruency is adopted to coarsely localize facial features, since prominent feature edges can be robustly located in the presence of shading and shadows. To accurately deal with features with less pronounced edges, final alignment is then computed from intrinsic gray-level information recovered using a proposed form of local intensity normalization. With this approach, our face alignment system works efficiently and effectively under a wide range of illumination conditions, as evidenced by extensive experimentation.
MRI-Guided Ventricular Tachycardia Ablation (2011)

Contrast-enhanced cardiac MRI can be safely performed in selected patients with ICDs and allows the integration of detailed 3D scar maps into clinical mapping systems, providing supplementary anatomic guidance to facilitate substrate-guided VT ablations.
Influence of temperature gradient on charge accumulation phenomena of GIS spacer under DC field (2018)

DC-GIS is used in HVDC systems because of its excellent insulation performance. However, when DC voltage is applied to DC-GIS, charges are accumulated on the surface of the insulator. This leads to decrease the breakdown voltage. Therefore, understanding charge accumulation phenomena is significant to make more reliable HVDC systems. In this paper, we focused on effects of the temperature gradient on the spacer to charge accumulation phenomena. We developed the experimental device which makes thermal distribution on an insulated model spacer and we measured charge distributions on it under temperature gradient. Also, numerical simulation was conducted to understand this phenomenon. We concluded that when temperature gradient is generated in the spacer, charging is more widely distributed.

Persistent Aerial Tracking system for UAVs (2016)

In this paper, we propose a persistent, robust and autonomous object tracking system for unmanned aerial vehicles (UAVs) called Persistent Aerial Tracking (PAT). A computer vision and control strategy is applied to a diverse set of moving objects (e.g. humans, animals, cars, boats, etc.) integrating multiple UAVs with a stabilized RGB camera. A novel strategy is employed to successfully track objects over a long period, by `handing over the camera' from one UAV to another. We evaluate several state-of-the-art trackers on the VIVID aerial video dataset and additional sequences that are specifically tailored to low altitude UAV target tracking. Based on the evaluation, we select the leading tracker and improve upon it by optimizing for both speed and performance, integrate the complete system into an off-the-shelf UAV, and obtain promising results showing the robustness of our solution in real-world aerial scenarios.
A novel page-based data structure for interactive walkthroughs (2009)

Given a data layout of a large walkthrough scene, we present a novel and simple spatial hierarchy on the disk-pages of the layout that has notable advantages over a conventional spatial hierarchy on the scene geometry. Assume that each disk-page consists of a set of triangles whose bounding boxes are computed. A spatial hierarchy of the walkthrough space is constructed, not with the given scene, but with the bounding boxes of disk-pages. The leaf nodes of the spatial-hierarchy refer directly to the page numbers of the pages of the bounding box it contains. We call this hierarchy on the pages as the disk-page hierarchy. We also propose a self-contained disk-page format that would suit this data structure well. Further, we present a new cache-oblivious graph-based data layout algorithm called the 2-factor layout that would preserve the proximity and orientation properties of the primitives in the layout. Walkthrough experiments have been conducted on a city scene consisting of over 110M triangles. Our system renders this scene on a laptop within a one pixel projection error at over 20 fps with simple texture substitution based simplification of distant objects, and with no explicit data/cache management.
Advances in martensitic transformations in Cu-based shape memory alloys achieved by in situ neutron and synchrotron X-ray diffraction methods (2012)

This article deals with the application of several X-ray and neutron diffraction methods to investigate the mechanics of a stress induced martensitic transformation in Cu-based shape memory alloy polycrystals. It puts experimental results obtained by two different research groups on different length scales into context with the mechanics of stress induced martensitic transformation in polycrystalline environment.
Lack of Subsensitivity to Albuterol After Treatment with Salmeterol in Patients with Asthma (1999)

The development of tolerance to the bronchodilator effects of beta2-agonists used in asthma therapy has been the subject of debate. We conducted two placebo-controlled crossover studies to assess the bronchodilator response to a short-acting beta2-agonist before and after chronic therapy with salmeterol. Patients in one study were corticosteroid-naive; patients in the other study were using inhaled corticosteroids. Changes in FEV1 after cumulative doubling doses of inhaled albuterol were assessed after a 2-wk beta-agonist washout period, before administering study medication on Day 1, and again after 28 d of therapy. Ipratropium bromide was provided as rapid-relief treatment for asthma, and use of any beta2-agonist except the study treatment was prohibited. On both assessment days for salmeterol, and during placebo administration periods, significant increases from predose FEV1 values were observed beginning with the lowest dose of albuterol and continuing throughout the dose-response assessment (p </= 0.001). These increases in FEV1 were maintained for 6 h after the last dose of albuterol (p < 0.05). There were no statistically significant differences in the albuterol dose response following salmeterol or placebo. These studies indicate that irrespective of concurrent corticosteroid treatment, chronic therapy with salmeterol does not result in tolerance to the bronchodilator effects of albuterol.
[Management, cost and mortality of a cohort of patients with advanced heart failure (the EPICAL study)]. (2001)

The objectives of this study are to describe the management, outcomes and costs of patients with severe chronic heart failure (CHF) and to identify the associated socio-demographic and clinical determinants. In 1994, the EPICAL study enrolled in a French region a representative cohort of 358 patients presenting for the first time with severe CHF (NYHA class III or IV) requiring hospitalization. The mean annual cost per patient was 125 652 FF, 92.6 per cent of which was associated with in-patient care including the index hospitalization. Ten per cent of patients contributed 33 per cent of the total cumulative costs. The rate of readmission was very high (20 per cent per month of follow-up) and appeared as a major cost driver. Three variables were identified in a multivariate logistic regression as the main contributors to cost: the presence of co-morbidity, renal insufficiency and marital status (living alone versus with spouse). These findings confirmed the major clinical and economic interest of any intervention that could lower the rate of readmissions in this group of patients.
Knock-limited performance of several internal coolants (1945)

Report presenting the effect of internal cooling on the knock-limited performance of AN-F-28 fuel in a CFR engine with the following internal coolants: water, methyl alcohol-water mixture, ammonia-methyl alcohol-water mixture, monomethyllamine-water mixture, dimethylamine-water mixture, and trimethylamine-water mixture.
Support of mobile TV over an HSPA network (2011)

This paper describes a quality of service (QoS) implementation in the UMTS Terrestrial Radio Access Network (UTRAN) to commercialize mobile television (TV) services with current High Speed Packet Access (HSPA) commercial devices, which do not support a streaming traffic class as defined by the 3rd Generation Partnership Project (3GPP). This implementation allows the mobile operators to offer a high quality of service for the end user in terms of reducing the need for re-buffering during the mobile TV session, while minimizing the impact of the service on the overall radio cell capacity. System level simulations relying on a Tier 1 operator use case have been generated to quantify the benefits streaming users experience due to this QoS implementation in the presence of background traffic in the same radio cell. The impact in terms of radio cell capacity is also evaluated.
Complete hepatocellular carcinoma necrosis following sequential porto-arterial embolization (2008)

Most patients with hepatocellular carcinoma (HCC) are not eligible for curative treatment, which is resection or transplantation. Two recent series have emphasized the potential benefits of preoperative arterio-portal embolization prior to surgical resection of such tumours. This preoperative strategy offers a better disease free survival rate and a higher rate of total tumor necrosis. In case of non resectable HCC it is now widely accepted that transarterial chemoembolization (TACE) leads to a better survival when compared to conservative treatment. Thus, the question remains whether combined portal vein embolization (PVE) may enhance the proven efficiency of TACE in patients with unresectable HCC. We herein report the case of a 56-year-old cirrhotic woman with a voluminous HCC unsuitable for surgical resection. Yet, complete tumour necrosis and prolonged survival could be achieved after a combined porto-arterial embolization. This case emphasizes the potential synergistic effect of a combined arterio-portal embolization and the hypothetical survival benefit of such a procedure, in selected patients, with HCC not suitable for surgery or local ablative therapy.
Kinetic modeling of GTL product distribution over a promoted cobalt catalyst (2012)

Qatar is the world leader in fuel production from gas-to-liquid (GTL) technology and home of the largest GTL plant in the world (Pearl GTL, a joint development by Qatar Petroleum and Shell). In the GTL process natural gas is converted into liquid fuels and waxes. Fischer-Tropsch synthesis (FTS) is the key part of that process. FTS is a heterogeneously catalyzed reaction in which a mixture of CO and H₂ is converted into a wide range of hydrocarbon products. Advanced design and optimization of large scale FTS reactors requires a detailed knowledge of reaction chemistry. Kinetic models used for this application need to be robust, physically reasonable and fundamental. This study will present one such a model. Experiments were conducted in a 1-L slurry reactor over 25% Co/0.48% Re/Al₂O₃ catalyst. A broad range of operating conditions was achieved (i.e., temperatures of 478, 493 and 503 K, pressures 1.5 and 2.5 MPa, H2/CO feed ratio 1.4 and 2.1 and gas space velocities of 1.0-22.5 NL/g-cat/h). Rate laws for the kinetic model have been derived using the CO-insertion mechanism and chain-length-dependent 1-olefin desorption concept. The model accounts for the formation of n-paraffins and 1-olefins. CO hydrogenation and insertion of CO into the growing chain are considered to be rate determining, as well as the chain termination steps. Non-isothermal model parameters are estimated by minimization of a multi-response objective function. A global minimum is obtained with the hybrid genetic algorithm and a total of 696 experimental responses used in the estimation. Estimated model parameters are meaningful, considering physicochemical tests and statistical tests. They are also in a good agreement with previously reported values for activation energies. The model fit is in good agreement with experimental data and the mean absolute relative residual (MARR) was 24%. The model also provides a good prediction of CO and H₂ rates of consumption, with a MARR of 17.7 and 16.1%, respectively. The main advantage of the proposed model is its ability to explain and predict the main features of GTL product distribution in a physically meaningful and fundamental way over a wide range of industrially relevant process conditions.
The sequence of the major protein stored in ovine ceroid lipofuscinosis is identical with that of the dicyclohexylcarbodiimide-reactive proteolipid of mitochondrial ATP synthase (1990)

The ceroid lipofuscinoses are a group of neurodegenerative lysosomal storage diseases of children and animals that are recessively inherited. In diseased individuals fluorescent storage bodies accumulate in a wide variety of cells, including neurons. Previous studies of these bodies isolated from tissues of affected sheep confirmed that the storage occurs in lysosomes, and showed that the storage body is mostly made of a single protein with an apparent molecular mass of 3500 Da with an N-terminal amino acid sequence that is the same as residues 1-40 of the c-subunit (or dicyclohexylcarbodi-imide-reactive proteolipid) of mitochondrial ATP synthase. In the present work we have shown by direct analysis that the stored protein is identical in sequence with the entire c-subunit of mitochondrial ATP synthase, a very hydrophobic protein of 75 amino acid residues. As far as can be detected by the Edman degradation, the stored protein appears not to have been subject to any post-translational modification other than the correct removal of the mitochondrial import sequences that have been shown in other experiments to be present at the N-terminal of its two different precursors. No other protein accumulates in the storage bodies to any significant extent. Taken with studies of the cDNAs for the c-subunit in normal and diseased sheep, these results indicate that the material that is stored in lysosomes of diseased animals has probably entered mitochondria and has been subjected to the proteolytic processing that is associated with mitochondrial import. This implies that the defect that leads to the lysosomal accumulation concerns the degradative pathway of the c-subunit of ATP synthase. An alternative, but less likely, hypothesis is that for some unknown reason the precursors of subunit c are being directly mis-targeted to lysosomes, where they become processed to yield a protein identical with the protein that is normally found in the mitochondrial ATP synthase assembly, and which then accumulates.
THE LONG ROAD TO A SUCCESSFUL ATMS INSTALLATION (1997)

While the technological advances associated with Advanced Traffic Management Systems have been substantial during the past 20 years, little has been done to improve the institutional process associated with their procurement and installation. The absence of significant progress is likely to reflect the difficulty of changing the regulations and procedures utilized by public agencies to define these processes. As a result of its recent experience with the installation of a traffic signal system in Northern Virginia, the Virginia Department of Transportation (VDOT) is considering techniques to improve the acquisition and installation process. Candidate techniques include the use of development and testing standards such as ISO9000 and the Capability Maturity Model, requiring increased visibility for system integrators on ATMS projects, and the use of expanded testing and approval steps during the system development. These techniques offer the potential benefit of reduced system life cycle cost, due to the fact that they provide a more rigorous development and testing process. In addition, all of the techniques being considered can be implemented within the framework of VDOT's existing acquisition and management policies. However, it is important to recognize that they are also likely to increase the initial cost of system acquisition because of the additional requirements being placed on the ATMS supplier. It is important to recognize that this increase in cost comes at a time when ATMS system costs are generally rising because of the complexity of this technology.

A Family-Based Analysis of Whether the Functional Promoter Alleles of the Serotonin Transporter Gene HTT Affect the Risk for Alcohol Dependence (1998)

A population association between a regulatory variation in the promoter of the serotonin transporter gene (HTT) and severe alcohol dependence was recently reported. We analyzed this potential association in a large number of systematically ascertained families in the United States; these families had at least three first-degree relatives who were alcohol-dependent. Analyses focused on individuals defined as alcohol-dependent by criteria from ICD-10 and on subsets of these individuals reporting withdrawal-related symptoms. Application of the transmission disequilibrium test did not provide support for either linkage or association between this functional polymorphism and alcohol dependence; there was no significant bias in the transmission of either allele to the alcohol-dependent offspring. We also report that African Americans differ from Caucasians in allele frequencies for this polymorphism.
The "<i>Nano</i>" World in Photodynamic Therapy. (2014)

Photodynamic Therapy (PDT) is an externally activated, photochemistry-based approach that generates cytotoxic reactive molecular species (RMS), which kill or modulate biological targets. PDT provides unique opportunities for applications of nanotechnology where light activation can trigger both direct RMS-mediated cytotoxic activity and the release of contents within the nanoconstructs (Figure 1). This process allows several species, working via different mechanisms and molecular targets to be activated or released in the right place and time, thus providing a distinctive approach to combination therapy. With advances in the development of miniaturized, even biodegradable, light sources and delivery systems, exciting possibilities of anatomical reach with PDT are being made possible. This brief article introduces aspects of interfaces of PDT and nanotechnology but, due to space constraints, makes no attempt to be a comprehensive review.
Conclusions (2013)

To conclude we may ask ourselves whether Spanish banking and monetary history does have ‘useful economics’ (paraphrasing McCloskey, 1976). We believe it does, and here are some of the topics on which we think this history throws light.
Intensity noise in ASK coherent lightwave receivers (1988)

The effect of local oscillator intensity noise on the performance of two and three-branch ASK homodyne receivers and single-branch ASK heterodyne receivers is investigated and an optimum local oscillator power is found. At optimum local oscillator power, both the three-branch and heterodyne receivers are found to have a somewhat better sensitivity than the two-branch receiver. If the local oscillator power is higher than the optimum value, the three-branch receiver is significantly less sensitive to intensity noise than the other two receivers.
