Design Of Communication Primitives For Satellite Networks Management (2010)

According to the mobility of the satellite network nodes and the characteristic of management domain dynamic partition in the satellite network, the login and logout mechanism of the satellite network dynamic management domain partition was proposed in the paper. In the mechanism, a ground branch-station sends the packets of login broadcasting to satellites in view. After received the packets, the SNMP agents on the satellites adopt link-delay test to respond. According to the mechanism, the SNMP primitives were extended, and the new added primitives were as follows: broadcasting, login, login confirmation,delay_testing, test responses, and logout. The definition of primitives, which followed RFC1157 criterion, could be encoded by the BER coding. The policy of the dynamic management domain partition on the basis of the login and logout mechanism, which was supported by the SNMP protocol, was realized by the design of the extended primitives.
Growth of semiconducting cubic boron nitride thin films. (1999)

This thesis details the growth mechanisms and deposition processes for semiconducting cubic boron nitride. Through experimental research a better understanding of the nucleation and growth mechanisms of the metastable cubic phase of boron nitride is achieved. A deposition process based on reduced-bias ion-assisted sputtering is developed. We found that relatively high nitrogen ion energy (&sim;100eV) necessary for initial nucleation and coalescence of c-BN islands can be reduced substantially (to &sim;60eV) leading to a dramatic improvement in the film quality in terms of fewer defects, larger grain size (&sim;2000A), lower residual stress, and well defined texture. It was found that the films grown at temperatures above 1050&deg;C are stable at ambient conditions and consist of pure-phase cubic boron nitride. An important aspect of the studies was the use of a novel technique for <italic>in-situ </italic> real-time stress monitoring which allowed us to produce films of cubic boron nitride with record thicknesses of more than 2mum. Cubic BN films prepared in this way are typically polycrystalline exhibiting partial crystallographic alignment relative to the substrate (i.e. textured morphology). A kinematic theory of reflection high energy electron diffraction (RHEED) is developed for textured polycrystalline thin films. Analytical expressions for RHEED patterns are derived for arbitrary texture situations and for any general crystallographic orientation that may be encountered in thin-film growth. We showed that the RHEED can be used as a fast and convenient tool for <italic>in-situ</italic> texture characterization. The approach also permits quantitative extraction of texture angular dispersion parameters which are useful for optimizing thin-film growth conditions. Analysis of RHEED patterns showed that c-BN films are textured with the texture axis along the (100) crystallographic direction perpendicular to the film surface with the texture spread of less than 20 degrees, a dispersion that can be reduced substantially by optimizing the growth conditions. The deposition technique devised in this research enables p-type semiconducting cubic boron nitride thin films with low a carrier activation energy of 60meV, high room temperature carrier mobility of &sim;500cm<super>2</super>/V-s and high room-temperature carrier concentrations of &sim;5 &middot; 10<super> 18</super>cm<super>-3</super>.
Flow cytometry immunophenotyping in integrated diagnostics of patients with newly diagnosed cytopenia: one tube 10‐color 14‐antibody screening panel and 3‐tube extensive panel for detection ofMDS‐related features (2015)

Acute leukemia, myelodysplastic syndromes (MDS), myeloproliferative neoplasms and lymphomas are the most prevalent diagnoses in adults presenting with new onset cytopenia. Here, we describe two 10-color panels of surface markers (screening and comprehensive panel) applied at the Flow Cytometry Laboratory, University Health Network, Toronto, ON, Canada. A 10-color flow cytometry is applied using the stain-lyse-wash sample preparation method. In patients with <10% blasts and no clear involvement by hematological malignancy based on cytomorphological evaluation of bone marrow (BM) smear, the recently published one-tube 10-color 14-antibody screening panel is applied. This panel allows detection of major B- and T-cell abnormalities, enumeration of cells in blast region (CD45 dim), and gives insight into myeloid BM compartment, including calculation of four-parameter score for MDS-related abnormalities. In patients who present with ≥10 - <20% blasts in blood or BM smears, a comprehensive three-tube panel of surface markers is used up front. The analysis is focused on the detection of abnormal antigen expression patterns not seen in normal/reactive BM, according to the guidelines developed by International/European LeukemiaNet Working Group for Flow Cytometry in MDS. In patients with ≥20% blasts, an additional tube is added to allow the detection of cytoplasmic markers necessary to diagnose mixed phenotype acute leukemia.

Canada’s Oil Sands Innovation Alliance: Delivering Environmental Performance (2014)

Abstract Imperial Oil, an affiliate of ExxonMobil Corporation, along with other 12 major oil companies in Canada formed an alliance of oil sands producers named Canada’s Oil Sands Innovation Alliance (COSIA). COSIA is a collaborative network with a mandate to accelerate the pace of improvement in environmental performance in Canada’s oil sands through capturing, developing and sharing innovative approaches and best practices. The alliance’s vision is to enable responsible and sustainable growth of Canada’s oil sands while delivering accelerated improvement in environmental performance through collaborative action and innovation. COSIA’s 13 member companies represent about 90 per cent of the crude oil production from the Canadian oil sands. Through COSIA, oil sands producers are sharing new technologies and launching new projects in four key environmental areas: land, water, tailings and greenhouse gases emission. COSIA provides the basis for the participating companies to collaborate and share innovation, knowledge, and technologies to minimize oil sands environmental impact in these priority areas. Launched in 2012, COSIA companies have shared about 560 technologies or innovations that cost roughly $900 million to develop. In addition, 185 projects such as commissioning new studies and developing targeted academic research chairs are moving forward under COSIA. COSIA is the overarching collaborative hub within which companies set priorities, drive and share innovation, and accelerate the pace of environmental performance improvements.
An advanced CSMA inter-vehicle communication system using packet transmission timing decided by the vehicle position (2004)

We examine the performance of inter-vehicle communication (IVC) systems using the IEEE802.11b standard CSMA scheme and a proposed system in which packet transmission timing is decided by the vehicle position. For the realization of safety cruise-assist systems by IVC systems, the spread of transceivers on vehicles is important. To improve the equipped rate of transceivers on vehicles, it is necessary that the implementation of more simple and cheaper IVC systems. One of the solutions is using conventional wireless LAN systems for IVC systems. So we evaluate the performance of an IVC system using the conventional IEEE802.11b CSMA system. In addition, we propose and evaluate an improvement scheme for solving the performance degradation caused by packet collision. The results of simulation show that the proposed scheme is superior to other schemes when the bit rate is low. Also, it is shown that the proposed scheme has the same or higher performance than the other schemes in high bit rate.
Radar/electro-optical data fusion for non-cooperative UAS sense and avoid (2015)

This paper focuses on hardware/software implementation and flight results relevant to a multi-sensor obstacle detection and tracking system based on radar/electro-optical (EO) data fusion. The sensing system was installed onboard an optionally piloted very light aircraft (VLA). Test flights with a single intruder plane of the same class were carried out to evaluate the level of achievable situational awareness and the capability to support autonomous collision avoidance. System architecture is presented and special emphasis is given to adopted solutions regarding real time integration of sensors and navigation measurements and high accuracy estimation of sensors alignment. On the basis of Global Positioning System (GPS) navigation data gathered simultaneously with multi-sensor tracking flight experiments, potential of radar/EO fusion is compared with standalone radar tracking. Flight results demonstrate a significant improvement of collision detection performance, mostly due to the change in angular rate estimation accuracy, and confirm data fusion effectiveness for facing EO detection issues. Relative sensors alignment, performance of the navigation unit, and cross-sensor cueing are found to be key factors to fully exploit the potential of multi-sensor architectures.
Probable Phaeoacremonium parasiticum as a cause of cavitary native lung nodules after single lung transplantation (2012)

Lung nodules after lung transplantation most often represent infection or post-transplant lymphoproliferative disorder in the allograft. Conversely, native lung nodules in single lung transplant recipients are more likely to be bronchogenic carcinoma. We present a patient who developed native lung cavitary nodules. Although malignancy was anticipated, evaluation revealed probable Phaeoacremonium parasiticum infection. Phaeoacremonium parasiticum is a dematiaceous fungus first described as a cause of soft tissue infection in a renal transplant patient. Lung nodules have not been previously described and this is the first case, to our knowledge, of P. parasiticum identified after lung transplantation.
4332 Development of a fracture reduction system for a direct reduction (2007)

Femoral neck fractures are increasing with the progress of an aging society. Problems of conventional reduction methods such as operation's burden, radiation expose and uncertainness of a fracture condition are previously discussed. We have developed a robot to assist the operation of fracture reduction to solve these problems. In this report, we present the fracture reduction system for direct reduction methods, which is more precise than indirect reduction methods. An operation mode of a robot that can control a pose of the bone fragment according to the bone coordination is proposed and is evaluated.
[500 years since the birth of G. Agricola, a physician and pharmacist in Jáchymov]. (1994)

Georgius Agricola (1494-1555) had graduated in medicine and then he chose the mining town of Jáchymov as the first place for practicing his profession and became the municipal physician and pharmacist there in 1527. There he wrote his first book on mining as well as a comparative study of ancient measures and weights, necessary for correct preparation of medicines according to the recipes of ancient authors. In 1533 he moved house to the Saxon town of Chemnitz. Besides practicing medicine he dedicated himself to mineralogy and mining, which made him famous. The paper also draws attention to some other writings of his, particularly his treatise on plague (1554).
Temperatures in the Upper Mesosphere and Lower Thermosphere from O2 Atmospheric Band Emission Observed by ICON/MIGHTI (2022)

Abstract The Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) was launched aboard NASA’s Ionospheric Connection (ICON) Explorer satellite in October 2019 to measure winds and temperatures on the limb in the upper mesosphere and lower thermosphere (MLT). Temperatures are observed using the molecular oxygen atmospheric band near 763 nm from 90–127 km altitude in the daytime and 90–108 km in the nighttime. Here we describe the measurement approach and methodology of the temperature retrieval, including unique on-orbit operations that allow for a better understanding of the instrument response. The MIGHTI measurement approach for temperatures is distinguished by concurrent observations from two different sensors, allowing for two self-consistent temperature products. We compare the MIGHTI temperatures against existing MLT space-borne and ground-based observations. The MIGHTI temperatures are within 7 K of these observations on average from 90–95 km throughout the day and night. In the daytime on average from 99–105 km, MIGHTI temperatures are higher than coincident observations by the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument on NASA’s TIMED satellite by 18 K. Because the difference between the MIGHTI and SABER observations is predominantly a constant bias at a given altitude, conclusions of scientific analyses that are based on temperature variations are largely unaffected.

Self‐Assembly Approach toward Chiral Bimetallic Catalysts: Bis‐Urea‐Functionalized (Salen)Cobalt Complexes for the Hydrolytic Kinetic Resolution of Epoxides (2011)

A series of novel bis-urea-functionalized (salen)Co complexes has been developed. The complexes were designed to form self-assembled structures in solution through intermolecular urea-urea hydrogen-bonding interactions. These bis-urea (salen)Co catalysts resulted in rate acceleration (up to 13 times) in the hydrolytic kinetic resolution (HKR) of rac-epichlorohydrin in THF by facilitating cooperative activation, compared to the monomeric catalyst. In addition, one of the bis-urea (salen)Co(III) catalyst efficiently resolves various terminal epoxides even under solvent-free conditions by requiring much shorter reaction time at low catalyst loading (0.03-0.05 mol %). A series of kinetic/mechanistic studies demonstrated that the self-association of two (salen)Co units through urea-urea hydrogen bonds was responsible for the observed rate acceleration. The self-assembly study with the bis-urea (salen)Co by FTIR spectroscopy and with the corresponding (salen)Ni complex by (1)H NMR spectroscopy showed that intermolecular hydrogen-bonding interactions exist between the bis-urea scaffolds in THF. This result demonstrates that self-assembly approach by using non-covalent interactions can be an alternative and useful strategy toward the efficient HKR catalysis.

Medical surveillance for hazardous drugs is infrequent, and consensus is lacking regarding standard practices. Further work is needed to minimize risk to health care workers.
Peptide 1018 inhibits swarming and influences Anr-regulated gene expression downstream of the stringent stress response in Pseudomonas aeruginosa (2021)

Pseudomonas aeruginosa is a ubiquitous opportunistic pathogen that causes considerable human morbidity and mortality, particularly in nosocomial infections and individuals with cystic fibrosis. P. aeruginosa can adapt to surface growth by undergoing swarming motility, a rapid multicellular movement that occurs on viscous soft surfaces with amino acids as a nitrogen source. Here we tested the small synthetic host defense peptide, innate defense regulator 1018, and found that it inhibited swarming motility at concentrations as low as 0.75 μg/ml, well below the MIC for strain PA14 planktonic cells (64 μg/ml). A screen of the PA14 transposon insertion mutant library revealed 29 mutants that were more tolerant to peptide 1018 during swarming, five of which demonstrated significantly greater swarming than the WT in the presence of peptide. Transcriptional analysis (RNA-Seq) of cells that were inoculated on swarming plates containing 1.0 μg/ml peptide revealed differential expression of 1,190 genes compared to cells swarming on plates without peptide. Furthermore, 1018 treatment distinctly altered the gene expression profile of cells when compared to that untreated cells in the centre of the swarm colonies. Peptide-treated cells exhibited changes in the expression of genes implicated in the stringent stress response including those regulated by anr, which is involved in anaerobic adaptation, indicative of a mechanism by which 1018 might inhibit swarming motility. Overall, this study illustrates potential mechanisms by which peptide 1018 inhibits swarming surface motility, an important bacterial adaptation associated with antibiotic resistance, virulence, and dissemination of P. aeruginosa.
Abstract IA17: New ways of targeting Ras (2017)

Abstract Activating K-Ras mutations occur frequently in many cancers, and account for about one million cancer deaths per year worldwide. Currently, no therapies exist that target K-Ras directly, and K-Ras cancers are very difficult to treat. Indeed, they are excluded from treatment with targeted agents such as tarceva and vemurafenib. The K-Ras protein is a member of a large family of related proteins, of which H-Ras and N-Ras are the closest relatives. Ablation of all three Ras genes is likely to be toxic, as these proteins are essential in most signaling transduction pathways. We therefore need to target the mutant oncoprotein itself, or target K-Ras, without affecting H-Ras or N-Ras. The striking similarity of these proteins makes this task challenging, together with the fact that the K-Ras gene expresses two splice variants, K-Ras 4A and K-Ras 4B, each of which can contribute to cancer. Nevertheless, differences do exist between these proteins, and ways in which these can be exploited will be discussed. One approach takes advantage of unique properties of K-Ras 4B, the other targets an amino acid that is shared between K-Ras isoforms, but is not present in H-Ras or N-Ras, or other members of the Ras family. K-Ras processing can be prevented by compounds that block the CAAX box cysteine. We have identified compounds that interact covalently with this cysteine and block prenylation by farnesyl transferase or geranylgeranyl transferase. These compounds reduce expression of K-Ras in cells and have specificity for K-Ras relative to H-Ras and N-Ras and represent another approach to targeting K-Ras specifically. We have also used new biophysical methods to target K-Ras, including second harmonic generation. This method detects small allosteric changes in proteins, and thus allows identification of small molecules that bind to K-Ras at novel allosteric sites. Drug resistance is likely to be a problem with Ras inhibitors, as it is for all types of cancer therapies. We have identified an approach to killing drug resistant cells that appears effective against a wide range of resistance mechanisms. This was achieved by targeting persister cells that survive targeted agents, but have unique properties that make them vulnerable to attack. The implications of this new strategy will be discussed.

Medical applications of diamond particles & surfaces (2011)

Diamond has been considered for use in several medical applications due to its unique mechanical, chemical, optical, and biological properties. In this paper, methods for preparing synthetic diamond surfaces and particles are described. In addition, recent developments involving the use of diamond in prostheses, sensing, imaging, and drug delivery applications are reviewed. These developments suggest that diamond-containing structures will provide significant improvements in the diagnosis and treatment of medical conditions over the coming years.
A study on the effect of ultrasonic beam skewing based on theoretical model approach in CCSS (1990)

Centrifugally Cast Stainless Steel generally shows similar structure to the weld in austenitic stainless steel in the point of casting. When examining this material ultrasonically, the beam does not generally propagate straightforward but rather deviates from its original direction and this phenomenon called skewing is originally caused by anisotropic material. In order to calculate the beam skewing effect theoretically, work has been performed based on a model approach which has regarded material itself as having been composed of multi-layered columnar dendrite structure and the result was compared with the one from experiment. The result from both theory and experiment showed good correlation and ultrasonic beam showed the least skewing with around 45 degree incident angle.
Cellular solids structure and properties (1997)

In this new edition of their classic work on Cellular Solids, the authors have brought the book completely up to date, including new work on processing of metallic and ceramic foams and on the mechanical, electrical and acoustic properties of cellular solids. Data for commercially available foams are presented on material property charts; two new case studies show how the charts are used for selection of foams in engineering design. Over 150 references appearing in the literature since the publication of the first edition are cited. The text summarises current understanding of the structure and mechanical behaviour of cellular materials, and the ways in which they can be exploited in engineering design. Cellular solids include engineering honeycombs and foams (which can now be made from polymers, metals, ceramics and composites) as well as natural materials, such as wood, cork and cancellous bone
Electrode Considerations for the Optical Enhancement of Organic Bulk Heterojunction Solar Cells (2011)

Abstract In this paper, we consider the optical effects in conventional and inverted bulk heterojunction organic solar cells associated with various electrodes, and perform a systematic study on the anode and cathode buffer layers commonly used in high performance devices. In the devices produced here, we determine that parasitic absorption by low work function metals such as calcium reduces photocurrent by 25%, and that parasitic reflection at interfaces between the transparent conducting oxide and metal oxide buffer layers can reduce photocurrent by more than 10%. We also quantify the impact of an optical spacer, and determine that this accounts for only a fraction of the improvement that can be gained through alternative electrode optimization routes. It is therefore our intention that this study serves as a guideline for the optimization of the electrodes of organic thin film photovoltaic devices.
