Pattern-Based Translation of BPMN Process Models to BPEL Web Services (2008)

The business process modeling notation (BPMN) is a graph-oriented language primarily targeted at domain analysts and supported by many modeling tools. The business process execution language for Web services (BPEL) on the other hand is a mainly block-structured language targeted at software developers and supported by several execution platforms. Translating BPMN models into BPEL code is a necessary step towards standards-based business process development environments. This translation is challenging since BPMN and BPEL represent two fundamentally different classes of languages. Existing BPMN-to-BPEL translations rely on the identification of block-structured patterns in BPMN models that are mapped onto structured BPEL constructs. This article advances the state of the art in BPMN-to-BPEL translation by defining methods for identifying not only perfectly block-structured fragments in BPMN models, but quasi-structured fragments that can be turned into perfectly structured ones and flow-based acyclic fragments that can be mapped onto a combination of structured constructs and control links. Beyond its direct relevance in the context of BPMN and BPEL, this article addresses issues that arise generally when translating between graph-oriented and block-structured flow definition languages.
[An early phase II study of CPT-11 (irinotecan hydrochloride) in patients with advanced breast cancer]. (1994)

An early phase II study of irinotecan (CPT-11) in patients with advanced or recurrent breast cancer was undertaken by a cooperative study group of 15 institutes in Japan. CPT-11 was administered by intravenous drip-infusion. The administration schedules were 100 mg/m2 weekly (regimen A), 150 mg/m2 biweekly (regimen B), and 200 mg/m2 every 3-4 weeks (regimen C). There were 4 partial responses (PRs), 12 cases with no changes (1 minor response) and 9 cases of progressive diseases with a response rate of 16% (4/25). One out of 7 patients on regimen A and 3 patients out of 15 patients on regimen C achieved PR with a response rate of 14% and 20%, respectively. In three out of 4 PRs, prior chemotherapy, endocrinotherapy or radiotherapy had failed. Major adverse reactions were leukopenia 28/33 (85%), neutropenia 19/25 (76%), anemia 15/33 (46%), nausea/vomiting 28/33 (85%), anorexia 25/33 (76%), diarrhea 22/33 (67%) and alopecia 20/33 (61%). The incidence of leukopenia and thrombocytopenia seemed to be higher in regimen C than regimen A, and diarrhea was also more severe in regimen C than regimen A. The recovery of leukopenia was delayed in some patients on regimen C. The results suggested that CPT-11 was effective against advanced or recurrent breast cancer. The recommended administration schedule for a late phase II study was thought to be 100 mg/m2 weekly, considering efficacy and safety.
Hexose metabolism in pancreatic islets. Inhibition of hexokinase (1984)

In islet homogenates, hexokinase-like activity (Km 0.05 mM; Vmax. 1.5 pmol/min per islet) accounts for the major fraction of glucose phosphorylation. Yet the rate of glycolysis in intact islets incubated at low glucose concentrations (e.g. 1.7 mM) sufficient to saturate hexokinase only represents a minor fraction of the glycolytic rate observed at higher glucose concentrations. This apparent discrepancy between enzymic and metabolic data may be attributable, in part at least, to inhibition of hexokinase in intact islets. Hexokinase, which is present in both islet and purified B-cell homogenates, is indeed inhibited by glucose 6-phosphate (Ki 0.13 mM) and glucose 1,6-bisphosphate (Ki approx. 0.2 mM), but not by fructose 2,6-bisphosphate. In intact islets, the steady-state content of glucose 6-phosphate (0.26-0.79 pmol/islet) and glucose 1,6-bisphosphate (5-48 fmol/islet) increases, in a biphasic manner, at increasing concentrations of extracellular glucose (up to 27.8 mM). From these measurements and the intracellular space of the islets, it was estimated that the rate of glucose phosphorylation as catalysed by hexokinase represents, in intact islets, no more than 12-24% of its value in islet homogenates.
Current-Mode Universal Filter Using Translinear Current Conveyors (2008)

This paper presents a new current-mode universal filter with three inputs and three outputs employing only two multiple-output current-controlled current conveyors and two grounded capacitors. The proposed circuit can simultaneously realize of lowpass, bandpass, highpass and bandstop current responses from same configuration. The proposed filter also enjoys an independent current control of parameters natural angular frequency and quality factor through adjusting the bias currents of the translinear current conveyors. The proposed configuration no requires of any cancellation constrain for realizing all the filter responses. The characteristics of the proposed circuit are simulated using PSPICE to confirm the theory.
ADAM (2001)

Intrusion detection systems have traditionally been based on the characterization of an attack and the tracking of the activity on the system to see if it matches that characterization. Recently, new intrusion detection systems based on data mining are making their appearance in the field. This paper describes the design and experiences with the ADAM (Audit Data Analysis and Mining) system, which we use as a testbed to study how useful data mining techniques can be in intrusion detection.
Substance P Innervation of Lumbar Spine Facet Joints (1993)

Sixteen adult human lumbar spine facet joints were harvested from patients undergoing various lumbar spine procedures. Diagnoses included degenerative disc disease, adult spinal deformity, facet joint degenerative arthritis, and degenerative spondylolisthesis. Facet joints were processed for routine hematoxylin and eosin staining. Immunohistochemical analysis was performed using a monoclonal antibody to substance P. All facets grossly exhibited evidence of degenerative disease, including cartilage surface irregularity and fibrillation. Histological examination of facets obtained from patients with degenerative spinal conditions demonstrated erosion channels extending through the subchondral bone and calcified cartilage into the articular cartilage. Immunostaining showed the presence of substance P-positive nerve fibers within these erosion channels, and also within marrow spaces. The presence of substance P nerve fibers within subchondral bone of degenerative lumbar facet joints implicates this type of joint in the etiology of low back pain.
Development of UV-photocathodes using GaN film on Si substrate (2008)

We developed GaN photocathodes for detecting ultraviolet radiation by using Mg-doped GaN. Crack-free, 200 nm thick GaN:Mg layers were grown by metal organic chemical vapor phase epitaxy (MOVPE) on a GaN template having a structure of undoped GaN/(AlN/GaN) multilayers on Si (111) substrate. The Mg concentration was varied in the range from 7×10<sup>18</sup> to 7×10<sup>19</sup> cm<sup>-3</sup>. The grown film was mounted in a phototube to operate in reflection mode; i.e. the light was incident from the photoemission side. The photoemission surface was activated by sequential adsorption of cesium and oxygen to reduce electron affinity, ensuring efficient electron emission. Photoemission spectrum was measured in the range of 200-600 nm. We found that the quantum efficiency of photoemission was affected by the crystallinity of GaN:Mg, depending on the concentration of Mg dopant and the growth pressure of GaN:Mg top photoemissive layer. The lower Mg concentration and higher growth pressure resulted in higher quantum efficiency. The obtained maximum quantum efficiency was 45% at 200 nm (6.2 eV) and 25% at 350 nm (3.54 eV). The elimination ratio between visible and UV light was 4 decades and the slope of cutoff was 10 nm per decade.

The influence of bond chemistry on immobilized enzyme systems for <i>ex vivo</i> use (1988)

The ideal derivatized support for the clinical use of an immobilized enzyme system should irreversibly bind active enzyme. We have investigated the behavior of heparinase and bilirubin oxidase immobilized via cyanogen bromide, tresyl chloride, epoxide, or carbodiimidazole activated natural and synthetic matrices. The protein bound to each activated support was 90% for cyanogen bromide (CNBr) activated agarose, 50-80% for tresyl chloride activated agarose, and 50% for oxirane activated acrylic (Eupergit C). The activity retention of immobilized heparinase was greatest (50%) with CNBr activated agarose while for the immobilization of bilirubin oxidase, the activity retention was greatest (25-30%) with tresyl chloride activated agarose and oxirane activated acrylic.The stability of the different covalent bonds was studied in vitro with radioiodinated enzymes. The leaching profiles showed the same trends for each support and chemistry. A plateau in protein leaching was reached after a few hours of incubation and the transient leaching period was well represented by a logarithmic function of time. The amount of enzyme released from the least stable support (CNBr activated agarose) in 24 h was injected intravenously in New Zealand white rabbits. Using an indirect enzyme-linked immunosorbant assay (ELISA), no immune response was detected. The transient leaching profile was shortened by washing the enzyme-support conjugate with 1M hydroxylamine, pH8.5 intermolecular cross-linking with glutaraldehyde also improves the enzyme-support stability. Tresyl chloride and oxirane activated supports produce bonds with improved stability without adversely affecting enzymatic activity.
Subpixel registration in renal perfusion MR image sequence (2005)

We propose a subpixel registration algorithm to deal with the motion induced by breathing for renal perfusion MR image sequences. Our approach minimizes an energy functional that integrates a motion model and temporal smoothness constraints. We then present a multistage level set method that segments different kidney structures in the registered MR image sequence. Tests with a rat kidney transplantation study show that the algorithm successfully compensates for the breathing motion and extracts the kidneys, cortex, medulla, and pelvis.
Modifying the red cell surface: towards an ABO‐universal blood supply (2007)

Eliminating the risk for ABO-incompatible transfusion errors and simplifying logistics by creating a universal blood inventory is a challenging idea. Goldstein and co-workers pioneered the field of enzymatic conversion of blood group A and B red blood cells (RBCs) to O (ECO). Using alpha-galactosidase from coffee beans to produce B-ECO RBCs, proof of principle for this revolutionary concept was achieved in clinical trials. However, because this enzyme has poor kinetic properties and low pH optimum the process was not economically viable. Conversion of group A RBCs was only achieved with the weak A2 subgroup with related enzymes having acidic pH optima. More recently, the identification of entirely new families of bacterial exoglycosidases with remarkably improved kinetic properties for cleaving A and B antigens has reinvigorated the field. Enzymatic conversion of groups A, B and AB RBCs with these novel enzymes resulting in ECO RBCs typing as O can now be achieved with low enzyme protein consumption, short incubation times and at neutral pH. Presently, clinical trials evaluating safety and efficacy of ECO RBCs are ongoing. Here, we review the status of the ECO technology, its impact and potential for introduction into clinical component preparation laboratories.
Trefoil peptides promote epithelial migration through a transforming growth factor beta-independent pathway. (1994)

The trefoil peptides, a recently recognized family of protease-resistant peptides, expressed in a regional specific pattern throughout the normal gastrointestinal tract. Although these peptides have been hypothesized to act as growth factors, their functional properties are largely unknown. Addition of recombinant trefoil peptides human spasmolytic polypeptide (HSP), rat and human intestinal trefoil factor (RITF and HITF) to subconfluent nontransformed rat intestinal epithelial cell lines (IEC-6 and IEC-17), human colon cancer-derived cell lines (HT-29 and CaCO2) or nontransformed fibroblasts (NRK and BHK) had no significant effect on proliferation. However addition of the trefoil peptides to wounded monolayers of confluent IEC-6 cells in an in vitro model of epithelial restitution resulted in a 3-6-fold increase in the rate of epithelial migration into the wound. Stimulation of restitution by the trefoil peptide HSP was enhanced in a cooperative fashion by the addition of mucin glycoproteins purified from the colon or small intestine of either rat or man, achieving up to a 15-fold enhancement in restitution. No synergistic effect was observed by the addition of nonmucin glycoproteins. In contrast to cytokine stimulation of intestinal epithelial cell restitution which is mediated through enhanced TGF beta bioactivity, trefoil peptide, and trefoil peptide-mucin glycoprotein stimulation of restitution was not associated with alteration in concentrations of bioactive TGF-beta and was not affected by the presence of immunoneutralizing anti-TGF beta antiserum. Collectively, these findings suggest that the trefoil peptides which are secreted onto the lumenal surface of the gastrointestinal tract may act in conjunction with the mucin glycoprotein products of goblet cells to promote reestablishment of mucosal integrity after injury through mechanisms distinct from those which may act at the basolateral pole of the epithelium.
Negative Hydrogen and Deuterium Ion Beams (1960)

The charge state of a monoenergetic beam of hydrogen atomic and molecular ions traversing a hydrogen gas target has been measured as a function of the energy of the beam and the thickness of the gas target. The yield of negative ions from protons has a maximum of 1.5% at 13 kev. From diatomic and triatomic molecular ions the maximum yields were 3.0% and 4.5% at 26 and 39 kev, respectively. The experiments have also been performed with deuterium ions traversing the hydrogen gas target. The deuterium results are almost identical with those of hydrogen if the energy scale for the hydrogen data is multiplied by two.
Texture of Chinese water chestnut: Involvement of cell wall phenolics (1995)

Abstract Chinese water chestnuts (CWC) fail to soften during cooking. This is due to thermal stability of cell wall polymers involved in cell‐cell adhesion. Information concerning these polymers was obtained by subjecting CWC tissues to a range of chemical and biochemical treatments designed to cleave selectively cell wall chemical bonds. Neither chelating agents nor weak base (Na 2 CO 3 , 0·05 M ) facilitated vortex‐induced cell separation (VICS) in fresh or canned tissues. However, VICS could be induced after extraction in dilute, cold alkali (0·1 M KOH), dilute hot acid, or a purified, specific endoxylanase. The CWC cell walls also exhibited considerable pH‐dependent autofluorescence which originated mainly from ferulic acid and its derivatives. This disappeared during alkali‐induced VICS. The results are consistent with the involvement of ferulic acid‐containing cell wall hemicelluloses in the thermal stability of cell‐cell adhesion and therefore texture in CWC tissues.
Experimental Study on Band Dispersion in Channels Structured with Micropillars (2006)

The band dispersion in channels with an orderly pillar structure with a pressure-driven liquid flow was determined. Several channels with different geometries were etched in a silicon wafer and enclosed by a glass wafer. The microchannels obtained had the same depth, pillar disposition, and overall porosity, but different pillar diameters and channel widths. The broadening of narrow bands of a fluorescent sample solution flowing through the channels was measured using a fluorescence microscope. It was shown that the peak dispersion occurring in the channels can be much lower than in conventional packed columns, as a consequence of the higher degree of order of the solid structure. Reduced plate heights of approximately 0.2 could be obtained for (nonretained) bands. No correlation was found between the aspect ratio (the ratio of the channel width and the pillar diameter) and band dispersion. The geometrical construction of the sidewall region was shown to play a critical role for channel performance. A good agreement was found with predictions for the optimal sidewall geometry obtained previously with simulation studies.
High efficiency electroabsorption modulator by using local quantum well intermixing (2016)

A new electroabsorption modulator (EAM) has been demonstrated using quantum well intermixing (QWI) method. Through local area of QWI, 110nm wavelength blue shift was attained in strip pattern of SiO2 deposition, forming optical waveguide structure and also leading to sensitive and efficiency voltage-driven optical modulation.
3-D analysis of permanent magnet linear synchronous motor with magnet arrangement using EMCN (1999)

In permanent magnet linear synchronous motor (PMLSM), detent force is generated between the PM and the primary core. The ripple of detent force produces both vibration and noise, and deteriorates the positioning control characteristics. In servo system, the reduction of detent force is very important for the high precision control performance.
Recent Developments in the Partial Oxidation of Methane to Syngas (2013)

Natural gas is catalytically converted into several bulk chemicals such as ammonia, methanol, dimethyl ether, and synthetic liquid fuels by Fischer-Tropsch synthesis and similar processes. The main step in the conversion of natural gas to these products is the production of synthesis gas with the desired composition ranging from H 2 /CO = 3:1 used for the production of ammonia to the 1:1 mixture preferred for production of dimethyl ether. Catalysts and catalytic processes are important in the production of synthesis gas from natural gas. In this work, relevant catalytic systems employed recently in the production of syngas by the catalytic partial oxidation of methane, as well as experimental evidences on the reaction mechanisms are examined. Differences in methane dissociation, binding site preferences, stability of OH surface species, surface residence times of active species and contributions from lattice oxygen atoms and support species are considered. The methane dissociation requires reduced metal sites, but at elevated temperatures oxides of active species may be reduced by direct interaction with methane or from the reaction with H 2 and CO (or C). The comparison of elementary reaction steps on Pt and Rh illustrates the fact that a key factor to produce hydrogen as primary product is a high activation energy barrier to the formation of OH. Another essential property for the formation of H 2 and CO as primary products is a low surface coverage of intermediates, such that the probability of O-H, OH-H and CO-O interactions is reduced.
Metal forming progress since 2000 (2008)

Considerable changes have occurred in metal forming in the last decade. A record of these changes can be found in keynote papers presented by the members of the Scientific Technical Committee—Forming, at the CIRP Annual General Meeting each year. The keynote papers are excellent references on important developments in metal forming and are used as a reference, globally. Not only is this paper a compendium of most of the keynotes presented, but from 2001 onward, it has updates on new information on five keynote subject areas. The authors of each keynote have written an update with new information that has developed since the writing of the keynote. The authors of each section are shown in order of presentation.
Soft output MAP equalization and trellis coded modulation for severe frequency-selective fading channels (2003)

The authors propose an algorithm that makes maximum a posteriori (MAP) equalization feasible for severe frequency-selective fading channels. In the algorithm the fully blown up intersymbol interference trellis is transformed into a set of parallel trellises with few states by means of tentative decisions. MAP equalization is performed on each subtrellis. The authors study the full MAP algorithm as well as reduced-complexity variants operating on parallel subtrellises. The proposed equalizer gives soft decisions which can be exploited by a successive decoder. The performance of the proposed algorithm was compared to M-algorithm equalization by extensive computer simulations. Results are presented for uncoded and trellis-coded signals for typical HF fading channels. The proposed soft output equalizer offers an additional soft decision coding gain of about 2.5 dB for short channel impulse responses and an improvement in bit error rate of two orders of magnitude for long channel impulse responses with a simple trellis code.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Sparsified SGD with Memory (2018)

Huge scale machine learning problems are nowadays tackled by distributed optimization algorithms, i.e. algorithms that leverage the compute power of many devices for training. The communication overhead is a key bottleneck that hinders perfect scalability. Various recent works proposed to use quantization or sparsification techniques to reduce the amount of data that needs to be communicated, for instance by only sending the most significant entries of the stochastic gradient (top-k sparsification). Whilst such schemes showed very promising performance in practice, they have eluded theoretical analysis so far. In this work we analyze Stochastic Gradient Descent (SGD) with k-sparsification or compression (for instance top-k or random-k) and show that this scheme converges at the same rate as vanilla SGD when equipped with error compensation (keeping track of accumulated errors in memory). That is, communication can be reduced by a factor of the dimension of the problem (sometimes even more) whilst still converging at the same rate. We present numerical experiments to illustrate the theoretical findings and the better scalability for distributed applications.
