Optimal commutation angles for current controlled switched reluctance motors (1996)

The paper considers the problem of choosing the turn-on and turn-off angles in current control of switched reluctance motors. The maximisation of mean torque is chosen as a primary objective, the expected benefits being a wider torque-speed envelope and faster transient response. With the assumption of flat-topped currents, the contributions of the turn-on and turn-off processes are shown to be independent, and can be optimised separately. The graph of mean torque as a function of turn-off angle has a well defined maximum. An analytical expression for the optimum turn-off is derived which takes saturation into account and is convenient for off-line generation of look-up tables giving the optimum turn-off angle as a function of speed and reference current. The predicted optimum turn-off angles agree satisfactorily with measurements on two motors taken over a wide range of operating conditions. The graph of mean torque as a function of turn-on angle is flat-topped and does not have a well defined local maximum. However, measurements show that over the range of turn-on angles defined by this flat-top, the efficiency varies monotonically with the turn-on angle. This suggests that the maximisation of efficiency for a given mean torque by varying the turn-on angle is a reasonable secondary objective, and one that can be done using existing techniques.
Ubiquitin E3 ligase Wwp1 negatively regulates osteoblast function by inhibiting osteoblast differentiation and migration (2013)

Ubiquitin E3 ligase-mediated protein degradation promotes proteasomal degradation of key positive regulators of osteoblast functions. For example, the E3 ligases--SMAD-specific E3 ubiquitin protein ligase 1 (Smurf1), Itch, and WW domain-containing E3 ubiquitin protein ligase 1 (Wwp1)--promote degradation of Runt-related transcription factor 2 (Runx2), transcription factor jun-B (JunB), and chemokine (C-X-C) receptor type 4 (CXCR-4) proteins to inhibit their functions. However, the role of E3 ligases in age-associated bone loss is unknown. We found that the expression level of Wwp1, but not Smurf1 or Itch, was significantly increased in CD45-negative (CD45(-)) bone marrow-derived mesenchymal stem cells from 6-month-old and 12-month-old wild-type (WT) mice. Wwp1 knockout (Wwp1(-/-)) mice developed increased bone mass as they aged, associated with increased bone formation rates and normal bone resorption parameters. Bone marrow stromal cells (BMSCs) from Wwp1(-/-) mice formed increased numbers and areas of alkaline phosphatase(+) and Alizarin red(+) nodules and had increased migration potential toward chemokine (C-X-C motif) ligand 12 (CXCL12) gradients. Runx2, JunB, and CXCR-4 protein levels were significantly increased in Wwp1(-/-) BMSCs. Wwp1(-/-) BMSCs had increased amount of ubiquitinated JunB protein, but Runx2 ubiquitination was no change. Knocking down JunB in Wwp1(-/-) BMSCs returned Runx2 protein levels to that in WT cells. Thus, Wwp1 negatively regulates osteoblast functions by affecting both their migration and differentiation. Mechanisms designed to decrease Wwp1 levels in BMSCs may represent a new approach to prevent the decrease in osteoblastic bone formation associated with aging.
Power and Powerlessness: Reading the Controversy over The Mighty Morphin Power Rangers (1998)

Dans cet essai, Mavis Reimer fait l'analyse du débat de 1994 qui a entraîné l'annulation de Ia série télévisée des Power Rangers. Selon elle, celui-ci nous en apprend beaucoup sur notre perception de l'enfance. En effet, selon certaines théories contemporaines, la littérature pour la jeunesse intériorise les relations de pouvoir entre les parents et leurs enfants; or,dans ce cas-ci, les parents se sont perçus comme sans défense. L'auteur nous convie donc à nous interroger sur les répresentations culturelles de ce rapport de force.\n\nIn this essay, Mavis Reimer analyses the rhetoric of the 1994 debate about the cancellation of The Mighty Morphin Power Rangers for what it can tell us about contemporary Canadian assumptions about childhood and "the child." Recent critics and theorists have read children's literature as replicating imperialist structures of power in its representation and production of the adult-child relation. In this debate, however, adults represent themselves as powerless. Reimer invites readers to consider what cultural function this representation might serve.

A surface acoustic wave dynamics control device by grating structure (2008)

We have developed the dynamic controlling system of surface acoustic wave (SAW) using micro electromechanical structures, using a plate with periodic convex structures as a mechanical switch of the SAW’s resonant condition. The effects of the geographical change on the substrate surface by the active control were investigated using the numerical analysis. And we verified the effect of spectrum shaping by the engraved grating structure, and the controlling effect of the resonant condition with the control plate on the grating structure experimentally.
Narrow optical interference fringes for certain setup conditions in multipass absorption cells of the Herriott type (1990)

We can select narrow FSR fringes in a multipass cell of the type described by Herriott et al. by setting the mirror spacing to give a particular type of beam path: M = odd integer, N = 4M +/- 4.
<scp>D</scp>‐Amino acids and <scp>D</scp>‐Tyr‐tRNA<sup>Tyr</sup> deacylase: stereospecificity of the translation machine revisited (2003)

Until 30 years ago, it had been considered that D-amino acids were excluded from living systems except for D-amino acids in the cell wall of microorganisms. However, D-amino acids, in the form of free amino acids, peptides and proteins, were recently detected in various living organisms from bacteria to mammals. The extensive distribution of bio-functional D-amino acids challenges the current concept of protein synthesis: more attention should be paid to the stereospecificity of the translation machine. Besides aminoacyl-tRNA synthetases, elongation factor Tu and some other mechanisms, D-Tyr-tRNA(Tyr) deacylases provide a novel checkpoint since they specifically recycle misaminoacylated D-Tyr-tRNA(Tyr) and some other D-aminoacyl-tRNAs. Their unique structure represents a new class of tRNA-dependent hydrolase. These unexpected findings have far-reaching implications for our understanding of protein synthesis and its origin.
An 8kB EEPROM-Emulation DataFLASH Module for Automotive MCU (2008)

An 8 kB E2FLASH test-chip is fabricated and reliability tests are executed. The paper shows the P/E cycle dependence of the threshold-voltage distribution and program/erase time. The threshold-voltage distribution does not degrade, and maintains enough margin to the wordline level (4.5 V) even after 1M P/E cycles. Erase time is 10 ms/block (average) for the first P/E cycle and 20 ms/block (average) after 1M P/E cycles. This is almost the same erase performance as on-board EEPROM, due to the DCNOR structure that does not use the read channel during program operation. On the other hand, program time increase is caused by charge trapping at tunnel oxide, but program time is 500 mus/word (average) even after 1M P/E cycles. The threshold-voltage shift value is only -1V after 1000 hr bake at Ta = 250 degC. These results indicate that the 8 kB E2FLASH is able to replace on-board EEPROM.
Enzyme-Linked Immunosorbent Assay for the Detection of Giardia lamblia in Fecal Specimens (1984)

An enzyme-linked immunosorbent assay (ELISA) was developed for the detection of Giardia lamblia in human feces. The assay could detect between 37 and 375 trophozoites from cultures and between 12.5 and 125 cysts purified from human stool. Stool specimens were positive by ELISA in 36 (92%) of 39 patients with giardiasis; negative specimens came from patients with low numbers of parasites in their stool. In 10 patients stools became negative by ELISA after successful treatment. Stool specimens were positive by ELISA in three (2%) of 128 patients without demonstrable Giardia organisms in their stools; one positive specimen was from a child with IgA deficiency and diarrhea who responded clinically to metronidazole. The ELISA is a simple, sensitive, and specific diagnostic test for G lamblia that will be useful in diagnosis, in follow-up treatment, and in large-scale studies directed at defining the epidemiology and pathophysiology of G lamblia infection.
Study of cure kinetics of diglycidyl ether of bisphenol A with Ni(II) and Cu(II) complexes of benzil bisthiosemicarbazone (2007)

Abstract The curing reaction kinetics of the diglycidyl ether of bisphenol A (DGEBA)‐based epoxy and inorganic complexes curing agents based on Ni(II) and Cu(II) chelates with benzil bisthiosemicarbazone LH 6 as a ligand was studied using differential scanning calorimetry (DSC). The curing reaction with the ligand and the complexes was characterized by high cure onset and peak maximum temperatures. The kinetics of the curing reaction was evaluated using three kinetic models; Kissinger, Ozawa‐Flynn‐Wall, and Málek. For the NiLH 4 and CuLH 4 the average values of E a were calculated to be 82.3 and 116 kJ/mol, respectively. For both complexes, their activation energies at 40 and 30 phr are equal. The values of activation energy ( E a ), and initial and maximum temperatures of the exothermic curing peak ( T i and T p ) of the ligand are smaller than those of the complexes, and the values of these parameters of the DGEBA/NiLH 4 system are lower than those of DGEBA/CuLH 4 system. These results indicate the order of reactivity of LH 6 ≫ NiLH 4 ≫ CuLH 4 toward epoxy resin. The effect of hardener concentration, heating rate, and type of metal ion on the cure kinetic parameters and the shape of DSC thermograms were investigated. © 2007 Wiley Periodicals, Inc.

Comparison of In-Situ to Ex-Situ Activities of Bitumen-Deactivated Catalysts (1996)

Catalyst deactivation runs were carried out in a flow reactor using bitumen and its maltene fraction as feeds in heptane solvent. Catalytic activity tests, using a mixture of model compounds, were performed to evaluate hydrogenation and C−N hydrogenolysis activities both directly after the aging run and again after the same aged catalyst had been posttreated by extraction with chloroform and resulfided. Two types of carbonaceous deposits were identified on the aged catalysts. One type, deposits left on the catalyst directly after the aging run, contained relatively large amounts of polymer-like material and caused significant losses in catalyst surface area. Catalytic activity was best related to residual, unblocked surface area and some poisoned sites. The second type, deposits remaining after extraction of the aged catalyst, was typical of conventional coke and did not block any pores. Subsequent activity tests showed activities were related to catalyst coke content.
Deformable structure from motion by fusing visual and inertial measurement data (2012)

Accurate recovery of the 3D structure of a deforming surgical environment during minimally invasive surgery is important for intra-operative guidance. One key component of reliable reconstruction is accurate camera pose estimation, which is challenging for monocular cameras due to the paucity of reliable salient features, coupled with narrow baseline during surgical navigation. With recent advances in miniaturized MEMS sensors, the combination of inertial and vision sensing can provide increased robustness for camera pose estimation particularly for scenes involving tissue deformation. The aim of this work is to propose a robust framework for intra-operative free-form deformation recovery based on structure-from-motion. A novel adaptive Unscented Kalman Filter (UKF) parameterization scheme is proposed to fuse vision information with data from an Inertial Measurement Unit (IMU). The method is built on a compact scene representation scheme suitable for both surgical episode identification and instrument-tissue motion modelling. Detailed validation with both synthetic and phantom data is performed and results derived justify the potential clinical value of the technique.
Forms of wearable computer (2003)

This paper introduces the microprocessor, communicating and sensing technologies relevant to wearable computing. It reviews the trends and challenges that form part of the evolution of computer technology, from a computer filling a room to a room full of invisible computers. Not all wearable computing systems require the same level of computing performance or functionality. A Processor Performance and Flexibility of Function (PPaFF) scale is introduced to classify wearable computing systems and is related to the prototypes described in Weiser's vision of the 21st century computer.
Pyranone Natural Products as Inspirations for Catalytic Reaction Discovery and Development (2015)

Natural products continue to provide a wealth of opportunities in the areas of chemical and therapeutic development. These structures are effective measuring sticks for the current state of chemical synthesis as a field and constantly inspire new approaches and strategies. Tetrahydropryans and tetrahydropyran-4-ones are found in numerous bioactive marine natural products and medicinal compounds. Our interest in exploring the therapeutic potential of natural products containing these motifs provided the impetus to explore new methods to access highly functionalized, chiral pyran molecules in the most direct and rapid fashion possible. This goal led to exploration and development of a Lewis acid-mediated Prins reaction between a chiral β-hydroxy-dioxinone and aldehyde to produce a pyran-dioxinone fused product that can be processed in a single pot operation to the desired tetrahydropyran-4-ones in excellent yield and stereoselectivity. Although the Prins reaction is a commonly employed approach toward pyrans, this method uniquely provides a 3-carboxy-trisubstituted pyran and utilizes dioxinones in a manner that was underexplored at the time. The 3-carboxy substituent served as a key synthetic handhold when this method was applied to the synthesis of highly functionalized pyrans within the macrocyclic natural products neopeltolide, okilactiomycin, and exiguolide. When employed in challenging macrocyclizations, this tetrahydropyranone forming reaction proved highly stereoselective and robust. Another major thrust in our lab has been the synthesis of benzopyranone natural products, specifically flavonoids, because this broad and diverse family of compounds possesses an equally broad range of biological and medicinal applications. With the goal of developing a broad platform toward the synthesis of enantioenriched flavonoid analogs and natural products, a biomimetic, asymmetric catalytic approach toward the synthesis of 2-aryl benzopyranones was developed. A bifunctional hydrogen bonding/Brønstead base catalyst was ultimately found to enable this transformation in analogous manner to the biosynthesis via the enzyme chalcone isomerase. Employing thiourea catalysts derived from the pseudoenantiomeric quinine and quinidine, alkylidene β-ketoesters can be isomerized to 3-carboxy flavanones and decarboxylated in a single pot operation to stereodivergently provide highly enantioenriched flavanones in excellent yield. This method was applied to the synthesis of the abyssinone family of natural products, as well as the rotenoid, deguelin. An analogous method to isomerize chalcones was developed and applied to the synthesis of isosilybin A. In both of these related endeavors, the need for novel enabling methodologies toward the efficient creation of targeted molecular complexity drove the discovery, development and deployment of these stereoselective catalytic transformations.
Personalizing PageRank for word sense disambiguation (2009)

In this paper we propose a new graph-based method that uses the knowledge in a LKB (based on WordNet) in order to perform unsupervised Word Sense Disambiguation. Our algorithm uses the full graph of the LKB efficiently, performing better than previous approaches in English all-words datasets. We also show that the algorithm can be easily ported to other languages with good results, with the only requirement of having a wordnet. In addition, we make an analysis of the performance of the algorithm, showing that it is efficient and that it could be tuned to be faster.
Mineral Soils as Carriers for <i>Rhizobium</i> Inoculants (1984)

Mineral soil-based inoculants of Rhizobium meliloti and Rhizobium phaseoli survived better at 4 degrees C than at higher temperatures, but ca. 15% of the cells were viable at 37 degrees C after 27 days. Soil-based inoculants of R. meliloti, R. phaseoli, Rhizobium japonicum, and a cowpea Rhizobium sp. applied to seeds of their host legumes also survived better at low temperatures, but the percent survival of such inoculants was higher than peat-based inoculants at 35 degrees C. Survival of R. phaseoli, R. japonicum, and cowpea rhizobia was not markedly improved when the cells were suspended in sugar solutions before drying them in soil. Nodulation was abundant on Phaseolus vulgaris derived from seeds that had been coated with a soil-based inoculant and stored for 165 days at 25 degrees C. The increase in yield and nitrogen content of Phaseolus angularis grown in the greenhouse was the same with soil-and peat-based inoculants. We suggest that certain mineral soils can be useful and readily available carriers for legume inoculants containing desiccation-resistant Rhizobium strains.
Reducing Power Consumption of Multiplier via Narrow-width Operand Detecting (2013)

Power consumption is a critical issue in functional unit design. Focusing on the condition of the positive narrow-width operands, this paper presents a low-power multiplier. Compared with the baseline multiplier, an additional width detector is employed in front of the operand register in the proposed multiplier. With the width information supplied by the width detector, computation modules in the multiplier could avoid unnecessary activities of the computation circuits when narrow-width operand appears. Experimental results show the multiplier could achieve an average of 21% power consumption when calculating the 32-bit operands with random valid bits, with 6.9% area overhead. The proposed design incurs 2.7% delay increase in the stage where the multiplier locates and the width detector also enlarges delay of the formal stage by 0.68ns in 180nm technology.

Dissolved Oxygen Removal in a Column Packed with Catalyst (1996)

The dissolved oxygen removal by H-O reaction in column packed with various catalysts wes examined. The catalysts employed were the prepared polymeric catalyst platinum on activated carbon, and Lewatit OC-1045 which is available commercially. The column experiments with the prepared polymeric catalyst showed the dissolved oxygen reduced to 35 ppb which is below the limit in feed water of power plants. This implies the likely application of the prepared catalyst for practical use. The activated carbon required the pre-treatment for the removal of dissolved oxygen, since the surface of activated carbon contains much oxygen adsorbed initially. The Lewatit catalyst exposed the best performance, however, the aged one showed the gradual loss of catalytic activity due to degradation of resin catalyst.
The nuclear factor κB inhibitor parthenolide restores ICI 182,780 (Faslodex; fulvestrant)–induced apoptosis in antiestrogen-resistant breast cancer cells (2005)

Abstract The molecular mechanisms underlying the acquisition of resistance to the antiestrogen Faslodex are poorly understood, although enhanced expression and activity of nuclear factor κB (NFκB) have been implicated as a critical element of this phenotype. The purpose of this study was to elucidate the mechanism by which NFκB up-regulation contributes to Faslodex resistance and to determine whether pharmacologic inhibition of NFκB by the small molecule parthenolide could restore Faslodex-mediated suppression of cell growth. Basal expression of multiple NFκB-related molecules in MCF7-derived LCC1 (antiestrogen-sensitive) and LCC9 (antiestrogen-resistant) breast cancer cells was determined, and cells were treated with Faslodex or parthenolide. The effect of these drugs either singly or in combination was assessed by cell proliferation, estrogen receptor (ER)–dependent transcriptional activation, cell cycle analysis, and apoptosis assays. Expression of the p65 NFκB subunit and the upstream NFκB regulator IκB kinase γ/NFκB essential modulator were increased in the resistant MCF7/LCC9 cells (P = 0.001 and 0.04, respectively). Whereas MCF7/LCC9 cells were unresponsive to Faslodex alone, parthenolide effectively inhibited MCF7/LCC9 cell proliferation and the combination of Faslodex and parthenolide resulted in a 4-fold synergistic reduction in cell growth (P = 0.03). This corresponded to a restoration of Faslodex-induced apoptosis (P = 0.001), with no observable changes in ER-dependent transcription or cell cycle phase distribution. Because parthenolide has shown safety in Phase I clinical trials, these findings have direct clinical relevance and provide support for the design of clinical studies combining antiestrogens and parthenolide in ER-positive breast cancer.
Radiographic Features of Intrinsic Ureteral Endometriosis: a case report (2005)

Endometriosis is defined as the presence of endometrial tissue in an ectopic position. It occasionally involves the urinary tract. Ureteral endometriosis may be either intrinsic or extrinsic, where the intrinsic ureteral endometriosis refers to disease caused by the actual invasion of the ureteral wall by the endometriosis. This form has often been mistaken for a primary ureteral neoplasm, with consequent nephroureterectomy. We reported a case of ureteral endometriosis in a 47 year-old female patient suffered from unilateral hydronephrosis. Left antegrade pyelography revealed a tubular filling defect in the left distal ureter with left hydronephrosis, and computed tomography (CT) demonstrated a soft tissue in the left distal ureter. Under the impression of malignant urothelial tumor, segmental resection of distal ureter was performed. The pathologic findings revealed elements of endometrial glands and stroma in the ureteral lumen. Extragenital intraureteral endometriosis was diagnosed. We should be aware of such diagnostic pitfalls to distinguish this lesion from polypoid ureteral tumor before operation.
