A QoS Metamodel and its Realization in a CORBA Component Infrastructure (2003)

This paper presents a generic model driven approach to enable Quality of Service (QoS) modeling and realization for component based middleware platforms. We describe a QoS metamodel that makes it possible to support multi category QoS instead of introducing a static set of QoS properties into the modeling method. The metamodel is integrated with the UML metamodel and the Component Implementation Framework (CIF) metamodel of the CORBA Component Model (CCM). Extensions to the CCM are described that are necessary to realize the QoS models in the software components and infrastructure. In addition an example QoS category is presented to demonstrate the application of the presented approach. Keywords: QoS control for Middleware, metamodeling, CORBA, CCM
Prevalence of Respiratory Syncytial Virus Subgroups Over Six Consecutive Outbreaks: 1981-1987 (1989)

Indirect immunofluorescence with strain-specific monoclonal antibodies was used to determine the phenotype of respiratory syncytial virus (RSV) isolates obtained from infants hospitalized in greater Boston over six successive outbreaks from 1981 to 1987. Of 981 isolates, 591 (60%) were classified as subgroup A and 383 (39%) as subgroup B. The prevalence of subgroups varied both between and within yearly outbreaks. In 1983-84 and 1984-85, both subgroups circulated concurrently and in almost equal proportions; in 1981-82, 1982-83, and 1985-86 subgroup A was dominant, accounting for 93% of all RSV isolates; and in 1986-87 subgroup B accounted for 89% of all RSV isolates. In some outbreaks both geographic and temporal clustering of subgroups occurred. No major differences in age, gender, or frequency of nosocomially acquired RSV between infants infected with either subgroup were seen, either overall or between or within yearly outbreaks. An expanded panel of monoclonal antibodies revealed further heterogeneity among subgroup A isolates. Comparison of these results with similar studies from other geographic locations indicated that the pattern of RSV subgroup prevalence is a localized phenomenon.
The Equivalence of Various Methods of Computing Biquad Coefficients for Audio Parametric Equalizers (1994)

Several authors have put forth design procedures for obtaining the coefficient values for second order digital filters to be used as parametric equalizers or &quot;presence&quot; filters. Given the EQ parameters, these differing design methods, having greatly disparate degrees of complexity, compute the filter coefficients. This paper shows that, with the possible exception of Q or bandwidth definition, all methods must be equivalent and the simplest method may be used. A method of computation is presented here in which the bandwidth is specified in octaves. 0
Live search for mobile:Web services by voice on the cellphone (2008)

Live search for mobile is a cellphone application that allows users to interact with Web-based information portals. Currently the implementation is focused on information related to local businesses: their phone numbers and addresses, directions, reviews, maps of the surrounding area, and traffic. This paper describes a speech-recognition interface which was recently developed for the application, which allows the users to interact by voice. The paper presents the overall architecture, the user interface, the design and implementation of the speech recognition grammars, and initial performance results indicating that for sentence level utterance recognition we achieve 60 to 65% of human capability.
Porphyrin Architectures Tailored for Studies of Molecular Information Storage (2004)

A molecular approach to information storage employs redox-active molecules tethered to an electroactive surface. Zinc porphyrins tethered to Au(111) or Si(100) provide a benchmark for studies of information storage. Three sets of porphyrins have been synthesized for studies of the interplay of molecular design and charge-storage properties: (1) A set of porphyrins is described for probing the effect of surface attachment atom on electron-transfer kinetics. Each porphyrin bears a meso-CH2X group for surface attachment where X = OH, SAc, or SeAc. (2) A set of porphyrins is described for studying the effect of surface-charge density in monolayers. Each porphyrin bears a benzyl alcohol for surface attachment and three nonlinking meso substituents of a controlled degree of bulkiness. (3) A set of porphyrins is described that enables investigation of on-chip patterning of the electrolyte. Each porphyrin bears a formyl group distal to the surface attachment group for subsequent derivatization with a molecular entity that comprises the electrolyte. Taken together, this collection of molecules enables a variety of studies to elucidate design issues in molecular-based information storage.
Vitamin B12 deficiency in Israel (2004)

Sirs, We were interested to read the report entitled, ‘Atrophic gastritis as a cause of hyperhomocysteinaemia’, by Santarelli et al., published in the January 2004 edition of Alimentary Pharmacology and Therapeutics, which also implicated vitamin B12 as a cause of elevated serum homocysteine.1 Although there is no doubt that atrophic gastritis is a common cause of vitamin B12 deficiency, we do not believe that this can explain all cases of vitamin B12 deficiency. For some reason, vitamin B12 deficiency is very common in Israel. A recent report found a frequency of vitamin B12 deficiency of 22.3% in Ashkenazi Jews and 40% in patients with Gaucher's disease.2 We have reported a frequency of vitamin B12 deficiency of 30% in 130 serial patients undergoing coronary angiography.3 Health Maintenance Organizations in Israel have responded to this high frequency of vitamin B12 deficiency by lowering the normal values of their laboratories.4 That there is a link between Helicobacter pylori infection and low vitamin B12 levels was illustrated by a report from Turkey that found an increase in vitamin B12 levels following H. pylori eradication.5 In addition, it should be remembered that levels of vitamin B12 that are near the lower limit of normal may still be associated with an increase in methylmalonic acid levels and homocysteine.6 Thus, many patients with low-normal levels of vitamin B12 may have silent vitamin B12 deficiency, which may contribute to hyperhomocysteinaemia. It would be interesting if Santarelli et al. examined their cohort of patients for methylmalonic acid levels and the effect of H. pylori eradication on homocysteine levels.
Stability of the flow in a differentially heated inclined box (1971)

The effect of sloping boundaries on thermal convection is studied theoretically and in the laboratory in the context of a model in which fluid is contained in a differentially heated rectangular box of small aspect ratio (depth/length), inclined at an angle δ to the vertical. Like its two limiting cases, Bénard convection and convection in the vertical slot, a basic state which exists for low Rayleigh numbers becomes unstable as this parameter is increased. The types of instability and indeed the manner in which the motions become turbulent depend crucially on δ. In our work with water the following general picture of the primary instabilities applies: For 90° > δ > 10° with the bottom plate hotter, the instabilities are stationary longitudinal convectively driven rolls with axes oriented up the slope. Near δ = 10° there is an upper and lower Rayleigh number cut off. If the Rayleigh number is too small diffusion damps the instabilities, but if it is too large they are damped by the development of a stable upslope temperature gradient in the mean flow. For 10° > δ > −10° (negative angles imply a hotter upper plate), transverse travelling waves oriented across the slope are the first instabilities of the mean flow. They obtain their kinetic energy via the working of the upslope buoyancy force. For - 10° > δ > −85° longitudinal modes are again observed. These are rather curious in that they may exist when the stratification $-\hat{g}\cdot\nabla T $ is everywhere positive. The necessary energy for these modes comes out of the mean velocity field and out of the mean available potential energy. Agreement between the stability theory and the experiments is generally quite good over the whole range of δ, considering the approximations involved in finding a suitable basic flow solution. For Rayleigh numbers less than ∼ 10 6 turbulence is only possible for positive angles. For 85° > δ > 20° the development of unsteadiness involves the occurrence and the breaking of wavy longitudinal vortices in a manner reminiscent of the development of turbulence in cylindrical Couette flow.
A Qualitative Morphological Comparison of Two Haemostatic Agents in a Porcine Liver Trauma Model (2013)

Background: Many surgical haemostatic agents are available which aim to reduce morbidity and mortality of bleeding, as well as associated costs. We used qualitative techniques to compare the effectiveness of two topical gelatine-based haemostatic agents in a porcine liver trauma model. Methods: We compared the activity of Floseal? (with human or bovine thrombin), Surgiflo? and Surgiflo? plus 5000 IU bovine thrombin per 10 mL of product (n = 6 test sites/group). Different clinical scenarios were evaluated in two anaesthetised piglets; normal physiological conditions (normotension and normothermia), and a status of hypotension, hypothermia and haemodilution, requiring inotropic support. Laparotomy was performed, and five identical stab wounds were made on each liver lobe. Four of these wounds were randomly treated with one of the agents under investigation, while one wound was kept as an untreated control. Haemostasis was observed during and immediately following surgery. After euthanisation, wounds were examined (blinded for treatment) macroscopically, microscopically and using scanning electron microscopic evaluation. Results: Surgiflo? produced some degree of clotting in 1/3 applications in both piglets. Co-treatment with thrombin resulted in a minor improvement in performance in the animal with normal physiological conditions (some degree of clotting in all wounds); no improvement was seen in the animal in a status of hypotension, hypothermia and haemodilution. Floseal? induced clotting in all wounds for both piglets. Microscopic and scanning electron microscope examination of the stab wounds demonstrated that Floseal? created a stable, dense agglomerate of gelatine and fibrin, which firmly adhered to the adjacent liver tissue. In wounds treated with Surgiflo? or Surgiflo? plus thrombin, the gelatine contained more air bubbles, resulting in less fibrin inclusion in the clot and weaker adhesion of the clot to the liver tissue. Conclusion: Floseal? created a dense and stable blood clot, even in a piglet with hypotension, hypothermia and haemodilution.
6-Gingerol alleviates exaggerated vasoconstriction in diabetic rat aorta through direct vasodilation and nitric oxide generation (2015)

The aim of the present study is to investigate the effect and potential mechanism of action of 6-gingerol on alterations of vascular reactivity in the isolated aorta from diabetic rats. Male Wistar rats were divided into two experimental groups, control and diabetics. Diabetes was induced by a single intraperitoneal injection of streptozotocin (50 mg kg(-1)), and the rats were left for 10 weeks to develop vascular complications. The effect of in vitro incubation with 6-gingerol (0.3-3 μM) on the vasoconstrictor response of the isolated diabetic aortae to phenylephrine and the vasodilator response to acetylcholine was examined. Effect of 6-gingerol was also examined on aortae incubated with methylglyoxal as an advanced glycation end product (AGE). To investigate the mechanism of action of 6-gingerol, the nitric oxide synthase inhibitor Nω-nitro-l-arginine methyl ester hydrochloride (100 μM), guanylate cyclase inhibitor methylene blue (5 μM), calcium-activated potassium channel blocker tetraethylammonium chloride (10 mM), and cyclooxygenase inhibitor indomethacin (5 μM) were added 30 minutes before assessing the direct vasorelaxant effect of 6-gingerol. Moreover, in vitro effects of 6-gingerol on NO release and the effect of 6-gingerol on AGE production were examined. Results showed that incubation of aortae with 6-gingerol (0.3-10 μM) alleviated the exaggerated vasoconstriction of diabetic aortae to phenylephrine in a concentration-dependent manner with no significant effect on the impaired relaxatory response to acetylcholine. Similar results were seen in the aortae exposed to methylglyoxal. In addition, 6-gingerol induced a direct vasodilation effect that was significantly inhibited by Nω-nitro-l-arginine methyl ester hydrochloride and methylene blue. Furthermore, 6-gingerol stimulated aortic NO generation but had no effect on AGE formation. In conclusion, 6-gingerol ameliorates enhanced vascular contraction in diabetic aortae, which may be partially attributed to its ability to increase the production of NO and stimulation of cyclic guanosine monophosphate.
Network Protocols and Tools to Help Produce Them (1987)

Protocols are the nervous system of computer-communication systems. They provide communication between remote as well as co-located pro­ cesses; they synchronize component tasks working towards a common goal. There are three reasons for the growing interest in protocols. First, now that it is economically feasible to build small processing units, distributed systems have become attractive for most applications. Protocols hold distributed systems together. Second, there is a growing desire to provide communication between heretofore independent information-handling systems. These systems are apt to function in different ways and have different internal languages, protocol conversion bridges the gaps. Third, as systems-even single-processor systems-provide more and more func­ tion, the only chance of containing complexity is to partition that function, using protocols to integrate the partitions. Most teleprocessing-equipment manufacturers have long since recog­ nized that to be able to interconnect their various products efficiently, they must define and abide by a well-defined architecture. Such an architecture defines (a) the format and structure of the messages that flow between the various system components, and (b) the protocols, the rules according to
Introduction (1989)

Biotechnology as a scientific endeavor has progressed more rapidly than many knowledgeable individuals expected. Just how rapidly is evidenced in the two papers on applications to laboratory animals and agricultural animals. Complex animals are an extremely demanding area for research and development, demanding because of the inherent complexity of the subjects and the exacting techniques required for the insertion of foreign genomes into the ova and the rearing of a viable animal.
Hormone-regulatable neoplastic transformation induced by a Jun-estrogen receptor chimera (1997)

The v-jun oncogene encodes a nuclear DNA binding protein that functions as a transcription factor and is part of the activator protein 1 complex. Oncogenic transformation by v-jun is thought to be mediated by the aberrant expression of specific target genes. To identify such Jun-regulated genes and to explore the mechanisms by which Jun affects their expression, we have fused the full-length v-Jun and an amino-terminally truncated form of v-Jun to the hormone-binding domain of the human estrogen receptor. The two chimeric proteins function as ligand-inducible transactivators. Expression of the fusion proteins in chicken embryo fibroblasts causes estrogen-dependent transformation.
Noisy binary search and its applications (2007)

We study a noisy version of the classic binary search problem of inserting an element into its proper place within an ordered sequence by comparing it with elements of the sequence. In the noisy version we can not compare elements directly. Instead we are given a coin corresponding to each element of the sequence, such that as one goes through the ordered sequence the probability of observing heads when tossing the corresponding coin increases. We design online algorithms which adaptively choose a sequence of experiments, each consisting of tossing a single coin, with the goal of identifying the highest-numbered coin in the ordered sequence whose heads probability is less than some specified target value. Possible applications of such algorithms include investment planning, sponsored search advertising, admission control in queueing networks, college admissions, and admitting new members into an organization ranked by ability, such as a tennis ladder.
Wrap-around type switch for ATM (1997)

Proposes a new wrap-around type switch structure based on omega networks. Their uniform interconnection pattern and symmetrical structure helps design a so-called wrap-around switch, The new switch deploys a self-routing mechanism between the input and the output ports. Another characteristic of the switch is the packet filters which are located right in front of the switch elements (SEs). This filtering operation greatly reduces the traffic in the switch fabric by allowing the incoming cells to reach their destination ports without going further in the network.
An EM algorithm for the block mixture model (2005)

Although many clustering procedures aim to construct an optimal partition of objects or, sometimes, of variables, there are other methods, called block clustering methods, which consider simultaneously the two sets and organize the data into homogeneous blocks. Recently, we have proposed a new mixture model called block mixture model which takes into account this situation. This model allows one to embed simultaneous clustering of objects and variables in a mixture approach. We have studied this probabilistic model under the classification likelihood approach and developed a new algorithm for simultaneous partitioning based on the Classification EM algorithm. In this paper, we consider the block clustering problem under the maximum likelihood approach and the goal of our contribution is to estimate the parameters of this model. Unfortunately, the application of the EM algorithm for the block mixture model cannot be made directly; difficulties arise due to the dependence structure in the model and approximations are required. Using a variational approximation, we propose a generalized EM algorithm to estimate the parameters of the block mixture model and, to illustrate our approach, we study the case of binary data by using a Bernoulli block mixture.
Development of Antibacterial-releasing Dental Composites with High Strength and Dentine Bonding (2015)

The thesis aim is to develop a dental composite with (1) high conversion/ depth of cure to provide good strength, (2) water sorption to compensate shrinkage and promote antibacterial release, and (3) added re-mineralising components and acidic monomers to enhance bonding. Conversion/ shrinkage, depth of cure, water sorption, and antibacterial (polylysine & chlorhexidine) release into distilled water versus simulated body fluid were assessed using FTIR, ISO 4049 (scraping test), gravimetrical studies, and UV spectroscopy respectively. Flexural strength/ modulus was assessed up to 6 months of water storage. Similarly bonding to moist ivory and human dentine was assessed via a push out and shear bond test. Factorial analysis was used to analyze the data. The results showed that a major factor affecting the conversion, and shrinkage was sample thickness. Similarly a major factor affecting the depth of cure was duration of light cure. In water sorption studies the major factors enhancing water sorption were use of distilled water, and polylysine. The chlorhexidine release was enhanced by the use of distilled water, while a higher polylysine release percentage was seen with lower levels of drug in the filler phase. The strength and modulus were decreased with the addition of reactive fillers. Lastly, adhesion was improved with the use of adhesive, and acidic monomers. The materials produced could potentially reduce bacterial micro leakage, which is the most common reason for failure.
Dual Attention GANs for Semantic Image Synthesis (2020)

In this paper, we focus on the semantic image synthesis task that aims at transferring semantic label maps to photo-realistic images. Existing methods lack effective semantic constraints to preserve the semantic information and ignore the structural correlations in both spatial and channel dimensions, leading to unsatisfactory blurry and artifact-prone results. To address these limitations, we propose a novel Dual Attention GAN (DAGAN) to synthesize photo-realistic and semantically-consistent images with fine details from the input layouts without imposing extra training overhead or modifying the network architectures of existing methods. We also propose two novel modules, i.e., position-wise Spatial Attention Module (SAM) and scale-wise Channel Attention Module (CAM), to capture semantic structure attention in spatial and channel dimensions, respectively. Specifically, SAM selectively correlates the pixels at each position by a spatial attention map, leading to pixels with the same semantic label being related to each other regardless of their spatial distances. Meanwhile, CAM selectively emphasizes the scale-wise features at each channel by a channel attention map, which integrates associated features among all channel maps regardless of their scales. We finally sum the outputs of SAM and CAM to further improve feature representation. Extensive experiments on four challenging datasets show that DAGAN achieves remarkably better results than state-of-the-art methods, while using fewer model parameters. The source code and trained models are available at https://github.com/Ha0Tang/DAGAN.
ERK5 and ERK2 Cooperate to Regulate NF-κB and Cell Transformation (2001)

We have previously demonstrated an involvement of MEK5 and ERK5 in RafBXB-stimulated focus formation in NIH3T3 cells. We find here that MEK5 and ERK5 cooperate with the RafBXB effectors MEK1/2 and ERK1/2 to induce foci. To further understand MEK5-ERK5-dependent signaling, we examined potential MEK5-ERK5 effectors that might influence focus-forming activity. Consistent with results from our focus-formation assays, constitutively active variants of MEK5 and MEK1 synergize to activate NF-kappaB, and MEK5 and ERK5 are required for activation of NF-kappaB by RafBXB. The MEK5-ERK5 pathway is also sufficient to activate both NF-kappaB and p90 ribosomal S6 kinase. Our results support the hypothesis that NF-kappaB and p90 ribosomal S6 kinase are involved in MEK5-ERK5-dependent focus formation and may serve as integration points for ERK5 and ERK1/2 signaling.
Epitaxy of Y-Ba-Cu-O thin films grown on single-crystal MgO (1990)

The epitaxy of a thin-film Y-Ba-Cu-O (YBCO) superconductor deposited on a single-crystal [001] MgO substrate was examined by transmission electron microscopy. The large lattice mismatch (8–10%) in the basal plane of YBCO and MgO is accommodated mainly by the formation of a polycrystalline, mosaic structure. The grain boundaries correspond to unique crystallographic interfaces, determined by the crystal symmetry of the substrate and the thin film.
Double-quadrupole DAF gun for self-converging color CRTs (2002)

The authors have developed a novel dynamic astigmatism and focus (DAF) gun for high-resolution tubes, called the dynamic-quadrupole DAF gun, which gives better round spots than existing DAF guns. This has been achieved by using an additional quadrupole lens adjacent to the triode part driven commonly by the same DAF dynamic voltage. Thus, the problem of the elliptically distorted spot-shape still remaining in the DAF gun has been solved. With the new gun a much rounder spot is obtained over the entire screen under a high-resolution tube condition, improving the horizontal resolution and reducing risks of moire appearance while maintaining the self-convergence.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
