Modeling, Simulation and Control of Flat Panel Solar Collectors with Thermal Storage for Heating and Cooling Applications (2013)

The focus of the present study is on the transient modeling of components in a solar system, controls, and heating and cooling loads. The system consists of solar flat plates and a thermal storage tank, which could provide a portion of heating requirements of a social enterprise building located in Winnipeg, Manitoba, Canada. This solar system and a natural gas hot water heater may replace the low efficiency boiler that supplies low quality steam for heat throughout the building using radiators. Results of the simulation performed in Simulink supports the proper selection of solar system components and controls that will be optimized for the climatic attributes of Winnipeg.
Complications maxillo-faciales associées à la pycnodysostose : présentation de deux cas cliniques et revue de la littérature (2015)

Introduction : La pycnodysostose est une maladie osseuse autosomique récessive, dont la prévalence est de 1/1,7 million. Elle se caractérise cliniquement par un nanisme, une ostéosclérose diffuse, une acro-ostéolyse des phalanges distales et une fragilité osseuse avec des fractures. La pycnodysostose présente des spécificités maxillo-faciales : une hypoplasie maxillaire et mandibulaire ainsi que des retards d’éruption dentaire. Observations : Les observations de deux patients atteints de pycnodysostose qui présentaient des complications maxillo-faciales caractéristiques de cette maladie sont rapportées et discutées. Les deux patients ont bénéficié d’une prise en charge en milieu hospitalier. Le premier patient souffrait d’une ostéomyélite maxillaire et mandibulaire. Le deuxième patient présentait des fractures mandibulaires pathologiques. Discussion : Ces observations sont ensuite comparées à celles retrouvées dans la littérature. La pycnodysostose est une maladie osseuse sclérosante due à une mutation du gène de la cathepsine K. La conséquence est une fragilité osseuse associée à de nombreuses fractures et ostéites identiques à celles des deux observations rapportées. Conclusion : Le patient atteint de pycnodysostose doit faire l’objet de soins dentaires réguliers pour éviter les complications osseuses et les avulsions dentaires, d’autant que la réhabilitation est compliquée par la morphologie des maxillaires et la structure osseuse.
Local chromatin structure at the ribosomal DNA causes replication fork pausing and genome instability in the absence of the <i>S. cerevisiae</i> DNA helicase Rrm3p (2004)

Lack of the yeast Rrm3p DNA helicase causes replication defects at multiple sites within ribosomal DNA (rDNA), including at the replication fork barrier (RFB). These defects were unaltered in rrm3 sir2 cells. When the RFB binding Fob1p was deleted, rrm3-generated defects at the RFB were eliminated, but defects at other rDNA sites were not affected. Thus, specific protein-DNA complexes make replication Rrm3p-dependent. Because rrm3-induced increases in recombination and cell cycle length were only partially suppressed in rrm3 fob1 cells, which still required checkpoint and fork restart activities for viability, non-RFB rrm3-induced defects contribute to rDNA fragility and genome instability.
Synthesis of four‐arm star poly(<scp>L</scp>‐lactide) oligomers using an <i>in situ</i>‐generated calcium‐based initiator (2009)

Abstract Using an in situ ‐generated calcium‐based initiating species derived from pentaerythritol, the bulk synthesis of well‐defined four‐arm star poly( L ‐lactide) oligomers has been studied in detail. The substitution of the traditional initiator, stannous octoate with calcium hydride allowed the synthesis of oligomers that had both low PDIs and a comparable number of polymeric arms (3.7–3.9) to oligomers of similar molecular weight. Investigations into the degree of control observed during the course of the polymerization found that the insolubility of pentaerythritol in molten L ‐lactide resulted in an uncontrolled polymerization only when the feed mole ratio of L ‐lactide to pentaerythritol was 13. At feed ratios of 40 and greater, a pseudoliving polymerization was observed. As part of this study, in situ FT‐Raman spectroscopy was demonstrated to be a suitable method to monitor the kinetics of the ring‐opening polymerization of lactide. The advantages of using this technique rather than FTIR‐ATR and 1 H NMR for monitoring L ‐lactide consumption during polymerization are discussed. © 2009 Wiley Periodicals, Inc.

A generic operations framework for discos in retail electricity markets (2009)

Summary form only given. A generic operations framework for a distribution company (disco) operating in a competitive electricity market environment is presented in this paper. The operations framework is a two-stage hierarchical model in which the first deals with disco's activities in the day-ahead stage, the day ahead operations model (DAOM). The second deals with disco's activities in real-time and is termed real-time operations model (RTOM). The DAOM determines the disco's operational decisions on grid purchase, scheduling of distributed generation (DG) units owned by it, and contracting for interruptible load. These decisions are imposed as boundary constraints in the RTOM and the disco seeks to minimize its short-term costs keeping in mind its day-ahead decisions. A case-study is presented considering the well-known 33-bus distribution system and three different scenarios are constructed to analyze the disco's actions and decision-making in this context..
DC Microgrid Protection: Review and Challenges (2018)

Successful system protection is critical to the feasibility of the DC microgrid system. This work focused on identifying the types of faults, challenges of protection, different fault detection schemes, and devices pertinent to DC microgrid systems. One of the main challenges of DC microgrid protection is the lack of guidelines and standards. The various parameters that improve the design of protection schemes were identified and discussed. Due to the absence of physical inertia, the resistive nature of the line impedance affects fault clearing time and system stability during faults. Therefore, the effectiveness of protection coordination systems with communication were also explored. A detailed literature review was done to identify possible grounding schemes and protection devices needed to ensure seamless power flow of grid-connected DC microgrids. Ultimately, it was identified that more analyses and experimentation are needed to develop optimized fault detection schemes with reduced fault clearing time.
Improved Quantification of DNA Methylation Using Methylation-Sensitive Restriction Enzymes and Real-Time PCR (2007)

Heterogeneity of cells with respect to the DNA methylation status at a specific CpG site is a problem when assessing methylation status. We have developed a simple two-step method for the quantification of the percent of cells that display methylation at a specific CpG site in the promoter of a specific gene. The first step is overnight digestion of genomic DNA (optimal conc. 20 ng/5 microl) with a relevant methylation-sensitive restriction enzyme (optimal 2 units). This is followed by real time PCR, using the SYBR Green method, with primers that bracket the site cleaved by the enzyme. By including fully methylated and fully non-methylated DNA in each PCR plate, the errors caused by non-specific digestion or incomplete digestion can be measured and used to adjust the raw results and thus increase specificity. The method can detect differences in methylation status if these are more than 10%. No specialized equipment is required beyond the real-time PCR system and the method can be adapted for any of the 53 commercially available methylation-sensitive restriction enzymes.
A Versatile Method for the Conjugation of Proteins and Peptides to Poly[2-(dimethylamino)ethyl methacrylate] (1999)

Random copolymers of 2-(dimethylamino) ethyl methacrylate (DMAEMA) with aminoethyl methacrylate (AEMA) were synthesized by radical polymerization. The amount of incorporated primary amino groups could be controlled by the feed ratio of AEMA to DMAEMA, and was varied from 2 to 6 mol %. Subsequently, protected thiol groups were introduced in a derivatization step with N-succinimidyl 3-(2-pyridyldithio)propionate (SPDP) and subsequent treatment with dithiothreitol (DTT). The obtained thiolated p(DMAEMA-co-AEMA) was conjugated to transferrin (Tf) or the F(ab') fragment of mAb 323/A3 via a disulfide linkage. Moreover, the maleimide derivative of the nuclear localization signal (NLS) decapeptide Gly-Pro-Lys-Lys-Lys-Arg-Lys-Val-Glu-Asp-NH(2) was coupled to the thiolated polymer via a thioether linkage. The coupling efficiency, as determined by GPC (Tf), SDS-PAGE [F(ab')], or (1)H NMR (NLS peptide) was 90-95% for the Tf conjugate, and more than 95% for the F(ab') conjugate and the NLS conjugate. The synthetic strategy described in this paper is a universal method for the preparation of conjugates of proteins and peptides with pDMAEMA in particular. This method can possibly be used to synthesize protein-polymethacrylate conjugates in general.

Highly Specific Bacteriophage-associated Polysaccharide Hydrolases for Klebsiella aerogenes type 8 (1976)

Two phage-bound polysaccharide hydrolases specific for Klebsiella aerogenes type 8 exopolysaccharides were isolated. Each enzyme was specific for the polysaccharide produced by the host strain. One enzyme hydrolysed a pyruvylated and acetylated polymer, while the other only acted on the substrate lacking these substituents. Both enzymes were endogalactosidases releasing tetrasaccharides from their substrates which were only hydrolysed to a limited extent.
Primary Living-Donor Liver Transplantation at the University of Chicago (2000)

The living-donor liver transplant recipient operation has undergone significant technical changes since its introduction in 1989. These changes have decreased the vascular complications associated with this type of graft. Avoiding the use of vascular conduits and performing microvascular hepatic artery anastomoses are the critical steps in improving graft survival.
The Search for Biomarkers of Long-Term Outcome after Preterm Birth (2016)

Preterm birth and survival rates are rising globally, and consequently there is a growing necessity to safeguard life-long health. Epidemiological and other studies from around the world point to a higher risk of adverse adult health outcomes following preterm birth. These reports encompass morbidities in multiple domains, poorer reproductive health, and reduced longevity. The contributions of genetic inheritance, intrauterine exposures, and postnatal care practices to this altered adult phenotype are not known. Early detection is essential to implement preventive measures and to test protective antenatal and neonatal interventions to attenuate aberrant health trajectories. A satisfactory biomarker of outcome must be predictive of later functional health and ideally remain stable over the period from infancy to childhood and adult life. To date, blood pressure is the index that best fulfils these criteria. High throughput 'omic' technologies may identify biomarkers of later outcome and health risk. However, their potential can only be realized with initial investment in large, longitudinal cohort studies, which couple serial metabolomic profiling with functional health assessments across the life course.
Object-oriented computer architectures for new generation of applications (1995)

Since the inception of von-Neumann architecture for computer design, there has been no new paradigms or revolutions in computer architectures. Computer applications have been increasing at an exponential rate, however, the basic computer architectures remained the same. The conventional computer architectures, which are based on primitive building blocks including arithmetic logic units, floating point processor units, logical shift units, and register file units created tremendous semantic-gap and inefficiencies in information system processing. It is about time to revisit the standard von-Neumann computation model and argue about its efficiencies, as we are entering into a new era of information processing where applications don't have any boundaries in computation, communication, and information storage. In this paper, we propose a revolutionary computer architecture which avoids the semantic-gap and inefficiencies, and is based on an object-oriented paradigm to provide the benefits of abstraction, inheritance, hierarchy, modularity, extensibility, and polymorphism. We will describe the fundamental building blocks for this architecture and propose a possible approach for implementing these new generation of computers which will not make software and hardware obsolete before coming to existence. We will present the design issues related to such architectures and research directions needed to study the feasibility of these architectures.
Spectroscopic Measurements of the Production and the Transport of CH Radicals in a Methane Plasma Used for the CVD of a-C:H (1990)

Spatial and temporal variations of CH radicals in an rf discharge in methane for the deposition of amorphous carbon film were measured by optical emission spectroscopy and laser-induced fluorescence (LIF) spectroscopy. The temporal variation of CH emission from the excited A 2 Δ state suggested that the electron energy was deeply modulated by the rf field. The spatial distribution of CH in the ground X 2 Π state showed a broader profile than the time-averaged emission profile of CH(A 2 Δ), indicating the broader spatial production pattern for the CH(X 2 Π) and its diffusional transport. The absolute density of CH(X 2 Π) was also obtained, from which the flux of CH onto the substrate was estimated. The density and the spatial profile of CH were strongly affected by diluent Ar gas. These results were compared with a simulation and discussed in relation to the film deposition.
The Molecular Pathology of Primary Brain Tumors (2013)

As the molecular basis of brain neoplasia continues to be elucidated, the pathologist is called upon more and more to provide not only a morphological diagnosis according to classic concepts, but also molecular data that offer additional information in terms of biological behavior and potential treatment response. In this review, we discuss the major brain tumor subtypes, some diagnostic issues that emphasize the need for molecular data, and existing putative molecular pathways associated with brain tumor subtypes. We further discuss the role of molecular tumor signatures as a means of determining prognosis and response to specific therapies. At present, it appears that 1p/19q assessment, as well as immunohistochemistry for IDH1 and β-catenin, should be available to all anatomic pathology laboratories that accession brain tumors. O6-methyl-guanine-DNA methyltransferase methylation analysis is an additional consideration for glioblastoma, although clinicians and patients may choose to forego this analysis if temozolomide will be used regardless of methylation status. Given the evolving nature of cancer biology and progress toward personalized medicine, it is likely, if not axiomatic, that molecular tumor characterization with continues to expand on a routine basis.

A 128-bit microprocessor compatible programmable correlator chip for use in synchronous communication (2003)

A single-chip microprocessor-compatible 128-b correlator is designed and implemented in a 3- mu m M/sup 2/CMOS process. Full-custom design techniques are applied to achieve the best tradeoff among chip size, speed, and power consumption. The chip is placed in a microprocessor-based portable data terminal using HF radio communication. It marks the beginning of a synchronous data stream received from the very noisy channel by detecting the synchronization (sync) word. The sync word can be detected for either inverted or noninverted input data streams. Two chips can be cascaded to make a 256-b correlator. The chip is fully programmable by a microprocessor to set the number of tolerable errors in detection and to select the bits of the 128-b (or 256-b) data stream to be used in the correlation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Approach to the study of small-perturbation stability of multimachine systems (1988)

A generalised approach to modelling multimachine systems is presented for stability analysis. The more systematic and realistic representation, accompanied by the development of powerful eigenvalue-analysis techniques, facilitates the study of the oscillation behaviour of complex interconnected systems, The study highlights the dependence of instability tendencies on large power angle differences between machines and incompatible excitation characteristics for the various machines. Based on this understanding, alternative practical remedies are investigated. The analytical approach developed, together with the discussions in the paper, also provides a firm basis for considering the introduction of PSSs into multimachine systems. Application of the modal and sensitivity methods to PSS study is described in a companion paper.
