Dynamic Execution of a Business Process via Web Service Selection and Orchestration (2015)

Dynamic execution of a business process requires the selection and composition of multiple existing services regardless of their locations, platforms, execution speeds, etc. Thus web service selection appears as a challenging and elusive task especially when the service task has to be executed based on user requirements at the runtime. This paper presents our Semantic-Based Business Process Execution Engine (SBPEE) for the dynamic execution of business processes by the orchestration of various exposed web services. SBPEE is based on our designed Project Domain Ontology (PrjOnt) that captures user specifications and SWRL rules which classify the user specification into a specific category according to the business logic and requirements of an enterprise. Based on this classification of the user project and requirements, our semantic engine selects web services from the service repository for the dynamic execution of a business process. SBPEE matches functional requirements of a web service and required QoS attributes to identify the list of pertinent candidate services to fulfil the complex business process transactions. Finally, we present our case study on Create Order business process that aims at creating an order for the customer by following various web services for its task completion.
Accuracy and precision of radiostereometric analysis in the measurement of three‐dimensional micromotion in a fracture model of the distal radius (2005)

The purpose of the current study was to verify the feasibility of radiostereometric analysis (RSA) in monitoring three-dimensional fracture micromotion in fractures of the distal radius. The experimental set-up consisted of a simulated model of an extra-articular Colles' fracture, including metallic beads inserted into the bone on either side of the fracture site. The model was rigidly fixed to high precision micrometer stages allowing controlled translation in three axes and rotation about the longitudinal and transverse axes. The whole construct was placed inside a RSA calibration cage with two perpendicular radiographic film cassettes. Accuracy was calculated as the 95% prediction intervals from the regression analyses between the micromotion measured by RSA and actual displacements measured by micrometers. Precision was determined as the standard deviation of five repeated measurements of a 200 microm displacement or a 0.5 degrees rotation along a specific axis. Translations from 25 microm to 5mm were measured with an accuracy of +/-6 microm and translations of 200 microm were measured with a precision of 2-6 microm. Rotations ranging from 1/6 degrees to 2 degrees were measured with an accuracy of +/-0.073 degrees and rotations of 1/2 degrees were measured with a precision of 0.025 degrees -0.096 degrees . The number of markers and their configuration had greater impact on the accuracy and precision of rotation than on those of translation. Aside from the unknown rate of clinical marker loosening, the current results favor the use of at least four markers in each bone fragment in distal radius fractures. These results suggest a strong rationale for the use of RSA as an objective tool for comparing different treatment modalities and novel bone graft substitutes aimed at stabilization of fractures of the distal radius.
Mass-preserving image registration using free-form deformation fields (2009)

Patient movement deteriorates image quality in medical imaging. For many applications, such as respiratory movement, image registration is being used to try to combine several (noisy) images into one high quality image. Non-rigid image registration is in many cases however an ill-posed problem. Even though images can be registered, the underlying deformation fields can be non-realistic and/or non-unique. Fidelity to the meaning of the image can help to reduce such problems. In PET and SPECT, voxel values represent concentration of the radiotracer. Therefore, if an organ such as a lung gets compressed, the image values increase. Similarly, density increases, and therefore CT Hounsfield units will change. In most approaches for image registration, these changes in image values are ignored. Here we use a (penalised) least-squares objective function, modified to take the change in image values due to local stretching/compression into account by multiplying the transformed image with the Jacobian-determinant of the transformation, as previously suggested by a number of authors. However, we minimize this objective function using a free-form deformation field (i.e. parametrised by a deformation vector for every voxel). To do this, we derive formulas for the derivative of the objective function w.r.t. the deformation vectors, which allows us to use a simple gradient descent algorithm to find the penalised least-squares solution. Our results indicate that the resulting objective function leads to unique solutions, even in uniform regions. However, regularisation is essential to prevent noise being registered as well.
Towards a Decision Support Personalised Self Management System for Chronic Conditions (2008)

People with long term health conditions often experience a radically reduced quality of life and suffer from a range of symptoms. Self management can encourage patients with a care support and reduce the burden of the costs of traditional face-to-face healthcare delivery. In this paper, we present a new approach to support selfmanagement for patients with long term conditions using assistive, rehabilitation and telecare technologies. A personalised self management system is proposed to effectively monitor, model and analyse relevant signs, symptoms and lifestyle consequences of long term conditions. Information on changes in chronic conditions will be fed back to the users in a meaningful and usable way and can be presented to patients to promote health behavior and to adjust life goals.
Strong Efficiency Improvement of SOI-LEDs Through Carrier Confinement (2007)

Contemporary silicon light-emitting diodes in silicon-on-insulator (SOI) technology suffer from poor efficiency compared to their bulk-silicon counterparts. In this letter, we present a new device structure where the carrier injection takes place through silicon slabs of only a few nanometer thick. Its external quantum efficiency of 1.4 • 10−4 at room temperature, with a spectrum peaking at 1130 nm, is almost two orders higher than reported thus far on SOI. The structure diminishes the dominant role of nonradiative recombination at the n+ and p+contacts, by confining the injected carriers in an SOI peninsula. With this approach, a compact infrared light source can be fabricated using standard semiconductor processing steps.
Changes in Perfusion-Weighted Magnetic Resonance Imaging after Carotid Angioplasty with Stent (2010)

Carotid artery stenosis due to arteriosclerosis increases the risk of cerebral ischemia via embolic phenomena or reduced blood flow. The changes in cerebral perfusion that may occur after treatment are not clearly understood. This study evaluated the changes in cerebral microcirculation following carotid angioplasty with stenting (CAS) under cerebral protection with filters using ultrafast gradient echo (GRE) perfusion weighted imaging (PWI) with magnetic resonance imaging (MRI). Prospectively, 21 cervical carotid stenosis patients, mean age 69.95 years, underwent MRI 12 h before and 72 h after CAS. PWI parameters were collected for statistical analysis: cerebral blood volume (CBV), mean transit time (MTT) and time to peak (TTP). Statistical analysis was applied to absolute parameters and to values normalized against those from the contralateral parenchyma. The main finding of this study was improved hemodynamics for the normalized data after CAS, shown by reduced MTT (p<0.001) and TTP (p=0.019) in the territory fed by the middle cerebral artery ipsilateral to the CAS. Absolute data showed increased blood volume in the cerebral hemispheres after CAS, which was more accentuated on the stent side (p=0.016) than the contralateral side (p=0.029). Early improvements in cerebral perfusion, mainly seen in the normalized data, were clearly demonstrated in the timing parameters - TTP & MTT - after CAS.
Vaccination with BV8S2 Protein Amplifies TCR-Specific Regulation and Protection Against Experimental Autoimmune Encephalomyelitis in TCR BV8S2 Transgenic Mice (1998)

TCR determinants overexpressed by autopathogenic Th1 cells can naturally induce a second set of TCR-specific regulatory T cells. We addressed the question of whether immune regulation could be induced naturally in a genetically restricted model in which a major portion of TCR-specific regulatory T cells expressed the same target TCR BV8S2 chain as the pathogenic T cells specific for myelin basic protein (MBP). We found vigorous T cell responses to BV8S2 determinants in naive mice that could be further potentiated by vaccination with heterologous BV8S2 proteins, resulting in the selective inhibition of MBP-specific Th1 cells and protection against experimental encephalomyelitis. Moreover, coculture with BV8S2-specific T cells or their supernatants reduced proliferation, IFN-gamma secretion, and encephalitogenic activity of MBP-specific T cells. These results suggest that immune regulation occurs through a nondeletional cytokine-driven suppressive mechanism.
Hybrid beamforming design for full-duplex millimeter wave communication dataset (2018)

Data associated with the publication: Katla, Satyanarayana; El-Hajjar, Mohammed; Hanzo, Lajos / Hybrid beamforming design for full-duplex millimeter wave communication. In: IEEE Transactions on Vehicular Technology, accepted on 27.11.2018.Paper abstract: Harnessing the abundant availability of spectral resources at millimeter wave (mmWave) frequencies is an attractive solution to meet the escalating data rate demands. Additionally, it has been shown that full-duplex (FD) communication has the potential of doubling the bandwidth efficiency. However, the presence of significant residual self-interference (SI), which is especially more pronounced at mmWave frequencies because of the non-linearities in the hardware components, erodes the full potential of FD in practice. Conventionally, the residual SI is canceled in the baseband using digital processing with the aid of a transmit precoder. In this work, we propose a hybrid beamforming design for FD mmWave communications, where the SI is canceled by the joint design of beamformer weights at the radio-frequency (RF) and the precoder as well as combiner in the baseband. Our proposed design preserves the dimensions of the transmit signal, while suppressing the SI. We demonstrate that our joint design is capable of reducing the SI by upto 30 dB, hence performing similarly to the interference-free FD system while being computationally efficient. Our simulation results show that the proposed design significantly outperforms eigen-beamforming.
Epidemiology of Shoe Wearing Patterns Over Time in Older Women: Associations With Foot Pain and Hallux Valgus (2016)

Women wear shoes with a lower heel and broader toe box as they age. Wearing constrictive footwear between the ages of 20 and 39 may be critical for developing hallux valgus in later life.
A small dose of human parathyroid hormone(1-34) increased bone mass in the lumbar vertebrae in patients with senile osteoporosis. (1995)

Intermittent treatment with human parathyroid hormone (hPTH) has been shown to increase cancellous bone mineral density (BMD) in osteoporosis, but its effects on cortical bone remain controversial. In this study, the effects of hPTH(1-34) administered at a dose of 6 micrograms (20 units) per day subcutaneously for 26 weeks were investigated in 16 patients with senile osteoporosis. The changes in BMD in lumbar vertebrae were measured using dual energy x-ray absorptiometry. BMD in the second metacarpal bone was simultaneously measured with radiogrammetry to find changes in BMD in cortical bone. Serum and urinary biochemical parameters were also evaluated. The lumbar BMD increased significantly at the end of the treatment without decrease in the cortical bone mass. Biochemical markers of bone formation were also elevated, while markers of bone resorption did not show striking changes during the treatment. In conclusion, daily administration of low doses of hPTH(1-34) stimulated bone formation and increased bone mass in patients with senile osteoporosis without combination with another therapeutic agent.
Feminism, Disability, and Embodiment (2002)

A recent exhibit on Feminism and Art at the National Museum of Women in the Arts included Barbara Bloom's 1995 work, Playboy in Braille. 1 For reasons that remain unknown to me, the museum chose to exhibit Bloom's work closed, leaving visitors to wonder about the relationship between a copy of a braille Playboy magazine and an exhibit on Feminism and Art. After all, Barbara Bloom did not create the braille edition of the magazine, so why would it be exhibited in an enclosed glass case crediting Barbara Bloom? After further investigation, I learned that Bloom's artistic addition to the magazine was the centerfold, a copy of Eve Arnold's 1954 photograph of Marilyn Monroe, fully clothed and reading James Joyce's Ulysses ([1922] 1992). 2 While perhaps not a conscious interrogation of the complex connections between feminism and disability studies, Barbara Bloom's Playboy in Braille nonetheless provides rich interpretive ground for considering how feminist disability studies draws upon and challenges analyses of bodily norms, identity, accommodation, representation, and oppression in both feminism and disability studies, themes addressed by the essays included in this volume.
Application of microwaves and millimeter waves for the characterization of teeth for dental diagnosis and treatment (1998)

This paper presents applications of microwaves and millimeter waves for the characterization of teeth. This is done by measuring the complex permittivity over the frequency range from 0.04 to 40 GHz. These measurements have revealed that dental caries are significantly more lossy to microwaves and millimeter waves than the healthy tooth, and this difference can be used for dental diagnosis. The experimental results have been confirmed by using the finite-difference time-domain (FDTD) method. In addition, millimeter-wave heating of the lossy dental caries can be used as a sterilization treatment. It is concluded that millimeter waves can be used for dental medical diagnosis as well as dental medical treatment.
A rat model of progressive chronic glomerular sclerosis (1992)

In order to evaluate a possible role of thromboxane A2 (TxA2) in the pathophysiology of chronic glomerular disease, we studied the effect of a 12-wk combined treatment with the thromboxane receptor blocker Daltroban (D) and the thromboxane synthesis inhibitor UK 38485 (UK) on glomerular function and morphology in a rat model of chronic progressive glomerular injury. The glomerular lesion was induced in unilaterally nephrectomized rats by the repeated i.v. injection of an antibody directed against mesangial cells. Control rats were uninephrectomized. Three months after the first antibody injection before D and UK treatment, albuminuria (35.8 +/- 3.6 mg/24 h) and glomerular TxB2 formation (146 +/- 20 pg/mg of protein/min) were significantly higher compared with control values (albuminuria, 14.3 +/- 3.5 mg/24 h; TxB2, 59 +/- 16 pg/mg/min). Six months after antibody, albuminuria in nephritic rats had increased to 135 +/- 17 mg/24 h. In nephritic rats treated with D plus UK, albuminuria (44 +/- 12 mg/24 h), however, was significantly (P less than 0.001) inhibited. Quantitative morphological analysis (glomerular damage index) 6 months after antibody revealed significantly (P less than 0.001) increased glomerular lesions in nephritic rats (0.353 +/- 0.095) compared with that in uninephrectomized controls (0.045 +/- 0.014). The treatment of rats with D and UK significantly (P less than 0.001) reduced the glomerular damage index (0.101 +/- 0.004) in nephritic rats. D plus UK treatment reduced glomerular TxB2 formation but increased prostaglandin E2 and 6-keto prostaglandin F1 alpha release by isolated glomeruli. This study demonstrates that interventional treatment with D and UK ameliorates albuminuria and glomerular morphological lesions in a rat model of immunologically induced progressive glomerular injury.
ICE: Inline calibration for memristor crossbar-based computing engine (2014)

The emerging neuromorphic computation provides a revolutionary solution to the alternative computing architecture and effectively extends Moore's Law. The discovery of the memristor presents a promising hardware realization of neuromorphic systems with incredible power efficiency, allowing efficiently executing the analog matrix-vector multiplication on the memristor crossbar architecture. However, during computations, the memristor will slowly drift from its initial programmed state, leading to a gradual decline of the computation precision of memristor crossbar-based computing engine (MCE). In this paper, we propose an inline calibration mechanism to guarantee the computation quality of the MCE. The inline calibration mechanism collects the MCE's computation error through ‘interrupt-and-benchmark (I&B)’ operations and predicts the best calibration time through polynomial fitting of the computation error data. We also develop an adaptive technique to adjust the time interval between two neighbor I&B operations and minimize the negative impact of the I&B operation on system performance. The experiment results demonstrate that the proposed inline calibration mechanism achieves a calibration efficiency of 91.18% on average and negligible performance overhead (i.e., 0.439%).

Direct Atom-Efficient Esterification between Carboxylic Acids and Alcohols Catalyzed by Amphoteric, Water-Tolerant TiO(acac)<sub>2</sub> (2005)

A diverse array of oxometallic species were examined as catalysts for a test direct condensation of benzoic acid and 2-phenylethanol in 1:1 stoichiometry. Besides group IVB MOCl2-xH2O and TiOX2-xH2O, group VB VOCl2-xTHF and group IVB TiO(acac)2 were found to be the most efficient and water-tolerant catalysts for the test reaction. The new neutral catalytic protocol with the optimal TiO(acac)2 tolerates many stereo/electronic structural variations in both (di)acid (1 degree -3 degrees alkyl and aryl) and (di)alcohol (1 degree, 2 degrees alkyl, and aryl) components with high chemoselectivity.
A Prototype Sourceless Kinematic-Feedback Based Video Game for Movement Based Exercise (2006)

This paper presents a prototype kinematic and audio feedback based video game, availing of a scalable motion capture acquisition system, based around a number of orientation sensors. The orientation sensors used are USB based tri-axis magnetic and gravitational field transducers. The novel video-game is capable of incorporating the real time data from these sensors to control an on screen avatar, which in turn can be programmed to give appropriate instructions to the user i.e. play a sound file, once the user obtains a certain posture. The video game is designed to promote physical exercise and movement based relaxation, in particular; yoga. In addition, design considerations; implementation and performance of the system are analyzed, discussed and the accuracy qualitatively analyzed by comparing movement data obtained from it to that of a validated motion analysis technique, the CODA motion analysis system.
Induction of a Mucosal Immune Response to the Streptococcal M Protein by Intramuscular Administration of a PADRE‐ASREAK Peptide (2004)

In a previous study, it was shown that an intramuscular administration of amino acid PADRE-ELDKWA sequence induced a mucosal immune response to a conserved epitope of human immunodeficiency virus in mice. In the same model, here it is shown that this method can be used with a selected peptide from the M protein of group A streptococci. The PADRE-ASREAK sequence was injected in mice by the intramuscular route. Antibodies against M protein were detected in extracts of mucosal tissues and in serum. The repertoire isotypes of serum immunoglobulin G (IgG) and mucosal IgA and IgG antibodies varied, according to the dose of injected peptide. The highest mucosal IgA antibody response was obtained with 0.01 micro g of antigen per injection, whereas the systemic IgG antibody response increased with 10 micro g of antigen. Mucosal antibody production against streptococci was confirmed by immunofluorescence analysis. These results provide evidence that this novel approach of mucosal vaccination may be of advantage for bacterial systems and suggest a new field of investigation based on synthetic peptide analogues.
Recent Progress in Triboelectric Nanogenerators as a Renewable and Sustainable Power Source (2016)

The newly developed triboelectric nanogenerators (TENGs) provide an excellent approach to convert mechanical energy into electricity, which are mainly based on the coupling between triboelectrification and electrostatic induction. The TENG has the potential of harvesting many kinds of mechanical energies such as vibration, rotation, wind, human motion, and even water wave energy, which could be a new paradigm for scavenging large scale energy. It also demonstrates a possible route towards practical applications for powering electronic devices. This paper presents a comprehensive review of the four modes of TENGs: vertical contact-separation mode, in-plane sliding mode, single-electrode mode, and free-standing triboelectric-layer mode. The performance enhancements of TENGs for harvesting energy as a sustainable power source are also discussed. In addition, recent reports on the hybridized nanogenerator are introduced, which may enable fully self-powered electronic devices. Finally, the practical applications of TENGs for energy harvesting are presented.

Optimization of particle size for high birefringence and fast switching time in electro-optical switching of graphene oxide dispersions (2015)

In order to use graphene oxide (GO) dispersions for electro-optical applications, both a high GO concentration and a high electrical sensitivity are essential; however, these have not been achieved to date. Here, we report that by optimizing the mean size of GO particles to approximately 0.5 μm, one can obtain a high GO concentration of up to 2 wt% and high electrical sensitivity simultaneously. By reducing the mean GO-particle size, the interparticle interaction and the rotational viscosity can be significantly reduced, and a high-concentration isotropic phase can be obtained. As a result, the maximum birefringence increases and the dynamic response becomes faster. However, further decrease of the mean size below 0.1 μm causes a decrease in the anisotropy of electrical polarizability, resulting in the reduction of the electrical sensitivity of GO dispersions.
