Visualaization. Visualization of Data Structures by Fuzzy Clustering of Graphs. (2000)

A visualization method is presented for data represented by a graph partitioned into fuzzy clusters. The data are arranged in a two-or three-dimensional space by correspondence analysis based on the memberships of the data in the obtained clusters. Data related by their links are represented by a directed graph or a bipartite undirected one. The fuzzy clusters are then extracted sequentially from the data based on this graph representation. At each stage of cluster extraction, memberships are calculated by solving an optimization problem using an iterative scheme. The data are then arranged in a two-or a three-dimensional space by correspondence analysis based on the memberships of the data. This data visualization method can be used to recommend movies by visual collaborative filtering and to visualize structures in a software program. It can be extended to more complexly structured data represented by the combination of a directed graph and a bipartite undirected one. This extended method can be used to search for Web pages by keywords and to recommend them as links. For example, the Web can be browsed to find information about sofas and carpets based on the impression they make and to visualy support their coordination.
A multi temporal trainable delay neural network (1994)

Neural networks have been used for analysis of temporally related patterns. Methods used include the encoding of temporal data for input to static networks, backpropagation through time, avalanche filters, recursive networks and temporal difference learning. Each of these methods attempt to learn temporal relationships through the use of varying amplification weights coupled with a constant periodic sampling of input signals. This paper presents a method of using delays rather than amplifications to encode temporal relationships directly into the network. This method improves memory usage by the network during simulation as well as reducing the required size of the network for temporal analysis.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Machine Learning : for Barcode Detection and OCR (2015)

Machine learning can be utilized in many different ways in the field of automatic manufacturing and logistics. In this thesis supervised machine learning have been utilized to train a classifiers for detection and recognition of objects in images. The techniques AdaBoost and Random forest have been examined, both are based on decision trees. The thesis has considered two applications: barcode detection and optical character recognition (OCR). Supervised machine learning methods are highly appropriate in both applications since both barcodes and printed characters generally are rather distinguishable. The first part of this thesis examines the use of machine learning for barcode detection in images, both traditional 1D-barcodes and the more recent Maxi-codes, which is a type of two-dimensional barcode. In this part the focus has been to train classifiers with the technique AdaBoost. The Maxi-code detection is mainly done with Local binary pattern features. For detection of 1D-codes, features are calculated from the structure tensor. The classifiers have been evaluated with around 200 real test images, containing barcodes, and shows promising results. The second part of the thesis involves optical character recognition. The focus in this part has been to train a Random forest classifier by using the technique point pair features. The performance has also been compared with the more proven and widely used Haar-features. Although, the result shows that Haar-features are superior in terms of accuracy. Nevertheless the conclusion is that point pairs can be utilized as features for Random forest in OCR.
Casper* (2009)

In this article, we present a new privacy-aware query processing framework, Capser *, in which mobile and stationary users can obtain snapshot and/or continuous location-based services without revealing their private location information. In particular, we propose a privacy-aware query processor embedded inside a location-based database server to deal with snapshot and continuous queries based on the knowledge of the user's cloaked location rather than the exact location. Our proposed privacy-aware query processor is completely independent of how we compute the user's cloaked location. In other words, any existing location anonymization algorithms that blur the user's private location into cloaked rectilinear areas can be employed to protect the user's location privacy. We first propose a privacy-aware query processor that not only supports three new privacy-aware query types, but also achieves a trade-off between query processing cost and answer optimality. Then, to improve system scalability of processing continuous privacy-aware queries, we propose a shared execution paradigm that shares query processing among a large number of continuous queries. The proposed scalable paradigm can be tuned through two parameters to trade off between system scalability and answer optimality. Experimental results show that our query processor achieves high quality snapshot and continuous location-based services while supporting queries and/or data with cloaked locations.
Toward a runtime system for reconfigurable computers: a virtualization approach (2009)

In this paper we propose a virtualization layer to handle the program execution on reconfigurable computers in order to address one of their biggest problems which is the management of the reconfigurable hardware in a multitasking environment. The virtualization layer is responsible for allocating the hardware at run-time based on the status of the system. Furthermore, it provides a consistent and low overhead interface to decouple the process of software development from hardware design which will result in the software to be independent of the underlying reconfigurable hardware. This paper discusses the virtual layer's specification and components. Our preliminary results for a prototype simulated on Molen hardware organization show a competitive performance comparing with an optimal hardware allocation.

Differential Effects of 1-Methylcyclopropene on Citrus Leaf and Mature Fruit Abscission (2004)

1-MCP is a gaseous ethylene binding inhibitor that controls or delays ethylene-related postharvest problems in a range of horticultural commodities. Our previous work demonstrated that exposure of calamondin to 1-MCP 16 hours before canopy sprays of ethephon greatly reduced unwanted leaf drop while only partially inhibiting the ability of ethephon to cause fruit loosening. The objective of this work was to determine whether formulated 1-MCP (SmartFresh) could be used in the field to stop defoliation caused by abscission agent applications without significantly altering abscission agent-induced fruit loosening. Spray solutions containing 400 mg·L -1 ethephon with 0, 1, 2.5, and 5 m m 1-MCP were applied to canopies of `Hamlin' and `Valencia' ( Citrus sinensis ). Timing of 1-MCP applications was a) 24 hours before, b) in combination with, or c) 24 hours after ethephon. Ethephon at 400 mg·L -1 significantly reduced fruit detachment force (FDF) but caused >70% leaf drop within 15 days after application in both cultivars. Applications of 1-MCP reduced ethephon-associated leaf abscission but had little effect on the ability of ethephon to reduce FDF. Timing of 1-MCP applications did not affect the ability of ethephon to cause fruit loosening; however, the best consistent treatment for control of leaf drop was achieved with the combined application of 5 m m 1-MCP and 400 mg·L -1 ethephon. 1-MCP was used in combination with the abscission agents coronatine, methyl jasmonate (MeJa) and 5-chloro-3-methyl-4-nitro-1 H -pyrazole (CMNP) to determine its effect on leaf drop and fruit loosening. Leaf drop in trees treated with ethephon, coronatine, and MeJa was reduced by addition of 1-MCP. However, fruit loosening was largely prevented when 1-MCP was used in combination with coronatine or MeJa. Like ethephon, CMNP-induced fruit loosening was not affected by 1-MCP. The results demonstrate the ability to control ethephon-induced leaf abscission without affecting mature fruit loosening by targeting ethylene binding in citrus.
Towards an ecosystem for semantics (2007)

Multimedia does not exhibit a unique semantics but multiple semantics that are influenced by many factors. Current approaches and systems lack from considering this problemin its entirety. What is needed is a holistic approach that describes and embraces the complex and challenging problem of multimedia semantics. Consequently, we are developing with the Semantics Ecosystem (SES) an approach that aimsat providing a "framework" for solving this problem. The SES defines five types of semantics and their relationships to each other and to the real world. In the paper, we present the SES and show its application to the domain of authoring multimedia albums. We show the benefits of having such a theoretical framework to handle the semantics of multimedia albums. The SES allows us to better understand, describe, and communicate the many different factors that are influencing multimedia semantics.
First-Trimester Diagnosis of Fetal Genetic Disorders (1985)

Chorionic villus sampling, which can be performed between the ninth and 11th weeks of gestation, provides fetal tissue for direct chromosomal and biochemical studies. Ongoing trials suggest that it will soon assume an important place in prenatal diagnosis by providing a much needed safe and accurate first-trimester approach to fetal genetic diagnosis.
Control of thermal therapies with moving power deposition field (2006)

A thermal therapy feedback control approach to control thermal dose using a moving power deposition field is developed and evaluated using simulations. A normal tissue safety objective is incorporated in the controller design by imposing constraints on temperature elevations at selected normal tissue locations. The proposed control technique consists of two stages. The first stage uses a model-based sliding mode controller that dynamically generates an 'ideal' power deposition profile which is generally unrealizable with available heating modalities. Subsequently, in order to approximately realize this spatially distributed idealized power deposition, a constrained quadratic optimizer is implemented to compute intensities and dwell times for a set of pre-selected power deposition fields created by a scanned focused transducer. The dwell times for various power deposition profiles are dynamically generated online as opposed to the commonly employed a priori-decided heating strategies. Dynamic intensity and trajectory generation safeguards the treatment outcome against modelling uncertainties and unknown disturbances. The controller is designed to enforce simultaneous activation of multiple normal tissue temperature constraints by rapidly switching between various power deposition profiles. The hypothesis behind the controller design is that the simultaneous activation of multiple constraints substantially reduces treatment time without compromising normal tissue safety. The controller performance and robustness with respect to parameter uncertainties is evaluated using simulations. The results demonstrate that the proposed controller can successfully deliver the desired thermal dose to the target while maintaining the temperatures at the user-specified normal tissue locations at or below the maximum allowable values. Although demonstrated for the case of a scanned focused ultrasound transducer, the developed approach can be extended to other heating modalities with moving deposition fields, such as external and interstitial ultrasound phased arrays, multiple radiofrequency needle applicators and microwave antennae.
Modeling and evaluation of broadband access networks for multimedia services (2002)

We categorize broadband multimedia services and typical access networks, and describe the service coverage of each access network. According to our analysis, we claim that ATM-based access networks are suitable for use in the future information infrastructures. The ATM-based access network is evaluated by its multicast function using near-video-on-demand and CATV service simulations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Stabilization of systems with deadzone nonlinearity (2002)

This paper studies the stabilization of control systems with deadband nonlinearity of unknown characteristics. A novel approach to treat the deadband is first proposed using techniques of saturation compensation, assuming crude estimates of gains and bounds for the saturation limiter. Stability of the compensated system is analyzed, revealing that for systems of conditional stability in the presence of deadzone nonlinearity, their stabilization is not possible for small inputs. However, proper stabilization always exists for regulatory control of large enough input magnitude. Simulated examples are given to illustrate the main results.
Models and Algorithms for Vehicle Scheduling (1995)

This paper considers the polynomially solvable case in which there is a single depot and one type of vehicle. Several assignment types of formulations are discussed and a new quasi-assignment algorithm is provided. This algorithm is based on an auction algorithm for the linear assignment problem. Furthermore, several ways for dealing with a large number of feasible connections between trips, a bottleneck for vehicle scheduling, are discussed. An important contribution of this paper is a computational study that compares our algorithms with the most successful algorithms for the vehicle scheduling problem, using both randomly generated and real life data. This can serve as a guide for both scientists and practioners. The new quasi-assignment algorithm is shown to be considerably faster for most of the test problems. This improvement in computation time is also very important when this particular vehicle scheduling problem appears as a subproblem in more complex vehicle and crew scheduling problems.
Beta-Blockers to Prevent Gastroesophageal Varices in Patients with Cirrhosis (2005)

Deep neural network trained with speaker representation for speaker normalization (2014)

A method for speaker normalization in deep neural network (DNN) based discriminative feature estimation for automatic speech recognition (ASR) is presented. This method is applied in the context of a DNN configured for auto-encoder based low dimensional bottleneck (AE-BN) feature extraction where the derived features are used as input to a continuous Gaussian density hidden Markov model (HMM/GMM) based ASR decoder. While AE-BN features are known to provide significant reduction in ASR word error rate (WER) with respect to more conventional spectral magnitude based features, there is no general agreement on how these networks can reduce the impact of speaker variability by incorporating prior knowledge of the speaker. An approach is presented in this paper where spectrum based DNN inputs are augmented with speaker inputs that are derived from separate regression based speaker transformations. It is shown the proposed method could reduce the WER by 3% relative to the best speaker adapted AE-BN CDHMM system.
Covalently grafted VEGF<sub>165</sub> in hydrogel models upregulates the cellular pathways associated with angiogenesis (2011)

Angiogenesis is an important biological response known to be involved in many physiological and pathophysiological situations. Cellular responses involved in the formation of new blood vessels, such as increases in endothelial cell proliferation, cell migration, and the survival of apoptosis-inducing events, have been associated with vascular endothelial growth factor isoform 165 (VEGF(165)). Current research in the areas of bioengineering and biomedical science has focused on developing polyethylene glycol (PEG)-based systems capable of initiating and sustaining angiogenesis in vitro. However, a thorough understanding of how endothelial cells respond at the molecular level to VEGF(165) incorporated into these systems has not yet been established in the literature. The goal of the current study was to compare the upregulation of key intracellular proteins involved in angiogenesis in human umbilical vein endothelial cells (HUVEC) and human microvascular endothelial cells (HMEC) seeded on PEG hydrogels containing grafted VEGF(165) and adhesion peptides Arg-Gly-Asp-Ser (RGDS). Our data suggest that the covalent incorporation of VEGF(165) into PEG hydrogels encourages the upregulation of signaling proteins responsible for increases in endothelial cell proliferation, cell migration, and the survival after apoptosis-inducing events.
Background-free coherent anti-Stokes Raman spectroscopy near transverse interfaces: a vectorial study (2008)

A full-vectorial theoretical investigation of the recently proposed background-free coherent anti-Stokes Raman scattering (CARS) spectroscopy near transverse interfaces [Phys. Rev. A, 77, 061802(R) (2008)] is presented. In this scheme, the field symmetries of the focused excitation beams are applied to recover the pure Raman spectrum of a medium forming a transverse interface with a nonresonant medium. We show that this method is robust to spatial shift of the excitation volume relative to the interface and does not depend on the linear polarizations states of the pump and Stokes beams. Finally, we extend the applicability of this scheme to a succession of planar interfaces between resonant and nonresonant media, which is potentially interesting for fast chemical analysis in microfluidic devices. Interestingly, this method can be extended to nondegenerated resonant four-wave-mixing processes to remove the nonresonant background.
The reactome pathway knowledgebase (2019)

Abstract The Reactome Knowledgebase (https://reactome.org) provides molecular details of signal transduction, transport, DNA replication, metabolism and other cellular processes as an ordered network of molecular transformations in a single consistent data model, an extended version of a classic metabolic map. Reactome functions both as an archive of biological processes and as a tool for discovering functional relationships in data such as gene expression profiles or somatic mutation catalogs from tumor cells. To extend our ability to annotate human disease processes, we have implemented a new drug class and have used it initially to annotate drugs relevant to cardiovascular disease. Our annotation model depends on external domain experts to identify new areas for annotation and to review new content. New web pages facilitate recruitment of community experts and allow those who have contributed to Reactome to identify their contributions and link them to their ORCID records. To improve visualization of our content, we have implemented a new tool to automatically lay out the components of individual reactions with multiple options for downloading the reaction diagrams and associated data, and a new display of our event hierarchy that will facilitate visual interpretation of pathway analysis results.

Extracellular matrix preparation of expanded polytetrafluoroethylene grafts seeded with endothelial cells: influence on early platelet deposition, cellular growth, and luminal prostacyclin release. (1991)

The importance of blood and extracellular matrix precoating of expanded polytetrafluoroethylene (ePTFE) grafts on the effectiveness of endothelial cell (EC) seeding was assessed in a canine experimental model. Part I of the study documented ex vivo platelet deposition in 256 ePTFE grafts, 6 cm x 4 mm internal diameter, after implantation as femoral artery-femoral vein or carotid artery-jugular vein arteriovenous shunts. These conduits were precoated with blood, fibronectin, laminin, or collagen type IV with laminin, after which they were seeded with enzymatically derived and cultivated venous canine endothelium at a density of 30,000 to 40,000 EC/cm2 of graft surface. Luminal deposition of Indium 111-labeled platelets, expressed as 10(8) platelets/cm2, at 30 minutes (n = 176) and 24 hours (n = 80), respectively, was 2.29 and 0.30 for blood, 2.83 and 0.37 for fibronectin, 0.99 and 0.08 for laminin, and 0.98 and 0.11 for collagen type IV with laminin. Part II of the study documented in vivo luminal EC coverage at 14 days of 6 cm x 4 mm internal diameter ePTFE femoral or carotid arterial grafts (n = 8) prepared in the same manner as part I ex vivo shunt grafts. EC coverage with blood, fibronectin, laminin, and collagen type IV with laminin preparation was 42%, 49%, 44%, and 52%, respectively. The graft:carotid artery ratio of luminal 6-keto-PGF1 alpha release at 14 days with these same four preparations was 0.38, 0.31, 0.35, and 0.32, respectively. Precoatings of ePTFE prostheses with fibronectin, laminin, and collagen type IV are known to enhance the initial attachment of seeded EC. Fibronectin caused an insignificant increase in early platelet accumulation; laminin or laminin with collagen type IV preparations were associated with significantly less (p less than 0.005) deposition of platelets when compared to whole blood preparations. Most importantly, none of the four preparation techniques resulted in different in vivo rates of EC growth or luminal release of prostacyclin from conduits studied 14 days after implantation.
