A hands-on learning and training program in power system protection (1997)

Postgraduate studies in electrical engineering have been an integral part of specialized training in several areas, such as power system analysis, reliability evaluation, power system control, system protection, material science, analog and digital electronics, signal processing and communications. Most universities provide courses and training in all or some of these disciplines. The University of Saskatchewan has had an active graduate program in electrical engineering since the late 1950s. Training in power system protection is as important, if not more, for engineers working in electric power utility and industrial sectors. It is interesting to note that, in North America, only a few universities offer courses in power system protection at the graduate and/or postgraduate levels. One of the universities that have offered courses for training in the area of power system protection for over thirty years is the University of Saskatchewan. This paper briefly describes the power system protection program offered at the University of Saskatchewan and outlines the facility that is used to provide hands-on experience in designing relays and applying them in utility and industrial environments. A brief account of the development of the courses in the program and the laboratory facilities is also provided.
Pathophysiological role of a factor affecting AGEs-RAGE interaction on endothelial cell responses (2018)

Objective: Advanced glycation end products (AGEs) are generated via Maillard reaction, in which non-enzymatic glycation occurs between reducing sugars (or their metabolites) and amine residues on biomolecules. AGEs stimulate vascular cells or macrophages through RAGE signaling pathway, and are involved in the exacerbation of tissue remodeling and the prolongation of inflammation. Therefore, it is likely that AGEs-RAGE signaling via RAGE stimulation is an important therapeutic target for the prevention or control of tissue remodeling and chronic inflammatory diseases.

OPERATION TO CONTROL GLAUCOMA (1934)

The experiments and operations described are offered as potential only in their application to relieve intra-ocular hypertension. The surgical technic is not difficult, and, although I have resorted to this procedure clinically in but three eyes (two cases), the favorable results to date lead me to offer this preliminary report. The possibility of establishing a fistulous tract from the anterior chamber through the suprachoroidal space and out through the sclera, for the control of intra-ocular hypertension, first occurred to me on Dec. 1, 1933. At that time, working with fresh pigs' eyes, I inserted flat, gold strips in a number of these eyes through the sclera in much the same way that a spatula is inserted in performing cyclodialysis. The conception was that by leaving the metal strip in the tract the superabundant aqueous could find its escape through the channel into the suprachoroidal space, with some absorption taking
Pump-Storage Integration with Renewables – Meeting the Needs Using Various Concepts (2010)

One of the primary tasks of Pumped Storage Power Plants (PSPP) in this era of rapidly growing renewable energy sources like wind and solar energy is to provide for energy storage while contributing to the stabilization of the electrical grid. Fast reaction to power unbalances and grid fluctuations may be achieved by using various configurations/types of pumped storage power plants, such as: - pump-turbines with fixed speed designed for fast reaction times - pump-turbines with variable speed - ternary units with hydraulic torque converter Each configuration has specific behaviours that offer different advantages and disadvantages. The current investigation illustrates the necessary considerations for determining what pumped storage characteristics are needed to support the grid with wind and other renewable, and how these characteristics vary according to the local regionâs installed mix and renewable energy generation situation and transmission constraints. Such considerations are necessary for correct decisions in the early planning stage for PSPP configurations.

Selling interrupt rights: A way to control unwanted e-mail and telephone calls [Technical forum] (2002)

Among the great irritations of modern life are unwanted e-mail (often referred to as “spam” <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> ) and unwanted telephone calls. In this article I present an approach to controlling these intrusions.
New EiC, Same Mission: Serving Energy Professionals and PES [Editors’ Voice] (2022)

Thirty-nine years ago, I joined IEEE as a Student Member of the Quebec Chapter, with control systems as my area of interest. When I attended my very first IEEE Power & Energy Society (PES) Winter Meeting in 1990 in Atlanta as a utility research engineer, I met legends of industry, like Prabha Kundur and Charles Concordia, and famous professors whom I admired. My immediate desire was to follow in their steps. During my early career, I was concerned about developing impactful technologies and writing research papers of archival value. To this aim, I engaged as a volunteer in various IEEE technical activities, mainly within the Electric Machinery and Power System Dynamic Performance Committees. This professional development led me to some consequential contributions to electric machinery standards and power grid control and protection systems. I was lucky enough to see some of them adopted and implemented in my own Hydro-Quebec, the public utility of the Province of Quebec in Canada, and elsewhere. This drive to design, build, implement, and report to peers was my main source of motivation during most of my career.
D10 Neurofilament light protein in blood predicts regional atrophy in huntington’s disease (2018)

<h3>Background</h3> Neurofilament light (NfL) protein in blood plasma has been proposed as a prognostic biomarker of neurodegeneration in a number of conditions, including Huntington’s disease (HD). Previous work has demonstrated elevated levels of NfL in HD gene expansion carriers when compared with controls, with NfL levels reflecting baseline motor and cognitive deficits as well as reduced global and regional brain volume. However, global measures provide limited insight into the regional distribution of NfL-associated pathology due to the HD gene mutation. <h3>Aims</h3> This study aims to establish the regional distribution of NfL-associated pathology in HD using voxel-based morphometry (VBM). <h3>Methods</h3> We examine associations between NfL measured in plasma and regionally-specific atrophy in cross-sectional (n=198) and longitudinal data (n=177) in HD gene expansion carriers from the international multisite TRACK-HD study. Using VBM we measured associations between baseline NfL levels and both baseline grey matter and white matter volume; and longitudinal change in grey matter and white matter over the subsequent three years in HD gene expansion carriers. <h3>Results</h3> After controlling for demographics, associations between increased NfL levels and reduced brain volume were seen in cortical and subcortical grey matter and within the white matter. After also controlling for known predictors of disease progression (age and CAG repeat length), associations were limited to the caudate and putamen. Longitudinally, NfL predicted subsequent occipital grey matter atrophy and widespread white matter reduction, both before and after correction for other predictors of disease progression. <h3>Conclusions</h3> These findings highlight the value of NfL as a dynamic marker of brain atrophy and, more generally, provide further evidence of the strong association between plasma NfL level, a candidate blood biomarker, and pathological neuronal change.
Light, the circadian clock, and sugar perception in the control of lignin biosynthesis (2005)

Experiments were undertaken to investigate some of the mechanisms that may function to regulate lignin biosynthesis (lignification) in Arabidopsis thaliana. Northern blot analyses revealed that several genes encoding enzymes involved in the synthesis of lignin monomers displayed significant changes in transcript abundance over a diurnal cycle. Northern blot analysis also suggested that some of the changes in diurnal transcript abundance were likely to be attributable to circadian regulation, whereas others were likely to be attributable to light perception. Comparison of circadian changes in transcript abundance of lignin biosynthetic genes between wild-type plants and the sex1 mutant, which is impaired in starch turnover, suggested that carbon availability related to starch turnover might determine the capacity to synthesize lignins. This hypothesis was supported by the observation that the sex1 mutant accumulated fewer lignins than wild-type plants. Consistent with the relationship between carbon availability and lignin accumulation, analysis of dark-grown wild-type A. thaliana seedlings uncovered a role for sugars in the regulation of lignin biosynthesis. Analysis of lignin accumulation, as determined by qualitative changes in phloroglucinol staining, suggested that metabolizable sugars positively influence the abundance of lignins. Transcriptome analysis supports the hypothesis that sugars are not merely a source of carbon skeletons for lignification, but they also function as a signal to enhance the capacity to synthesize lignins.

Noninvasive seizure prediction using autonomic measurements in patients with refractory epilepsy (2018)

There is resurgent interest in the role played by autonomic dysfunction in seizure generation. Advances in wearable sensors make it convenient to track many autonomic variables in patient populations. This study assesses peri-ictal changes in surrogate measures of autonomic activity for their predictive value in epilepsy patients. We simultaneously recorded fronto-central surface EEG and submental EMG to score vigilance state, intracranial EEG (iEEG) to compute several electrophysiological variables (EV), and measurements (heart rate, blood volume pulse, skin impedance, and skin temperature) relevant to autonomic function (AV) using a wrist-worn sensor from three patients. A naïve Bayes classifier was trained on these features and tested using five-fold cross- validation to determine whether preictal and interictal sleep (or wake) epochs could be distinguished from each other using either AV or EV features. Of 16 EV features, beta power, gamma power (30-45 Hz and 47-75 Hz), line length, and Teager energy showed significant differences for preictal versus interictal sleep (or wake) state in each patient (t test: $p<0.001$). At least one AV was significantly different in each patient for interictal and preictal sleep (or wake) segments ($p<0.001$). Using AV features, the classifier labeled preictal sleep epochs with 84% sensitivity, 79% specificity, and 64% kappa; and 78%, 80% and 55% respectively for preictal wake epochs. Using EV, the classifier labeled preictal sleep epochs with 69% sensitivity, 64% specificity, and 33% kappa; and 15%, 93% and 10% respectively for preictal wake epochs.
Preparation of pH sensors by covalent linkage of dye molecules to the surface of polystyrene optical fibers (1991)

Abstract Functional Bromothymol Blue dyes containing amino groups in position 3 have been immobilized on the surface of chlorosulfonated polystyrene fibers and characterized by ESCA. Upon laser irradiation, a modified fiber has been used as an antenna fiber in a twisted pair of plastic optical fibers immersed in aqueous solutions having various pH. The light transmitted to the receiving fiber depends on pH values. This device can be used as a pH sensor.
The Variation of the Glass Structure and Foaming Characteristics of Volcanic Glass Particles with Different Shape in the Shirasu (1982)

Role of peroxisome proliferator-activated receptor- (PPAR ) in bezafibrate-induced hepatocarcinogenesis and cholestasis (2004)

Prolonged administration of peroxisome proliferators to rodents typically leads to hepatocarcinogenesis. Peroxisome proliferator-activated receptor-alpha (PPARalpha) is required to mediate alterations in PPARalpha target gene expression, repress apoptosis, enhance replicative DNA synthesis, oxidative stress to DNA and hepatocarcinogenesis induced by the relatively specific PPARalpha agonist, Wy-14,643. Interestingly, administration of the less specific PPARalpha agonist, bezafibrate, leads to a modest induction of PPARalpha target genes in the absence of PPARalpha expression. In these studies, the role of PPARalpha in modulating hepatocarcinogenesis induced by long-term feeding of 0.5% bezafibrate was examined in wild-type (+/+) and PPARalpha-null (-/-) mice. The average liver weight was significantly higher in (+/+) and (-/-) mice fed bezafibrate than controls, but this effect was considerably less in (-/-) mice as compared with similarly treated (+/+) mice. Increased levels of mRNA encoding cell cycle regulatory proteins and DNA repair enzymes were found in (+/+) mice fed bezafibrate, and this effect was not found in (-/-) mice. In mice fed bezafibrate for 1 year, preneoplastic foci, adenomas and a hepatocellular carcinoma were found in (+/+) mice, while only a single microscopic adenoma was found in one (-/-) mouse. This effect was observed in both Sv/129 and C57BL/6N strains of mice, although only preneoplastic foci were observed in the latter strain. Interestingly, hepatic cholestasis was observed in 100% of the bezafibrate-fed (-/-) mice, and this was accompanied by significantly elevated hepatic expression of mRNA encoding bile salt export pump and lower expression of mRNA encoding cytochrome P450 7A1, consistent with enhanced activation of the bile acid receptor, farnesoid X receptor. Results from these studies demonstrate that the PPARalpha is required to mediate hepatocarcinogenesis induced by bezafibrate, and that PPARalpha protects against potential cholestasis.
Low-complexity power-scalable multi-view distributed video encoder + (2007)

To meet the requirements of resource-limited video sensors, lowcomplexity video encoding technique is highly desired. In this paper, we propose a low-complexity power-scalable multi-view distributed video encoding scheme by using the correlations among video frames from adjacent video sensor nodes via robust media hashing extracted at encoder and using the global motion parameters estimated and fed back from the decoder. In addition, the proposed method is power-scalable, which is adaptive based on the available power supply of the video sensor. The powerrate-distortion behavior of the proposed scheme is also analyzed in order to maximize the video quality under limited sensor resource allocation. Index Terms — Low-complexity video coding, multi-view distributed video coding, power-scalable video coding, wireless video sensor networks 1.

Comparison of Three Molecular Assays for Rapid Detection of Rifampin Resistance in Mycobacterium tuberculosis (1998)

Multidrug-resistant Mycobacterium tuberculosis (MDR-TB) is an emerging problem of great importance to public health, with higher mortality rates than drug-sensitive TB, particularly in immunocompromised patients. MDR-TB patients require treatment with more-toxic second-line drugs and remain infectious for longer than patients infected with drug-sensitive strains, incurring higher costs due to prolonged hospitalization. It is estimated that 90% of United Kingdom rifampin-resistant isolates are also resistant to isoniazid, making rifampin resistance a useful surrogate marker for multidrug resistance and indicating that second- and third-line drugs to which these isolates are susceptible are urgently required. Resistance in approximately 95% of rifampin-resistant isolates is due to mutations in a 69-bp region of the rpoB gene, making this a good target for molecular genotypic diagnostic methods. Two molecular assays, INNO-LiPA Rif.TB (Innogenetics, Zwijndrecht, Belgium) and MisMatch Detect II (Ambion, Austin, Tex.), were performed on primary specimens and cultures to predict rifampin resistance, and these methods were compared with the resistance ratio method. A third method, the phenotypic PhaB assay, was also evaluated in comparison to cultures in parallel with the genotypic assays. In an initial evaluation 16 of 16, 15 of 16, and 16 of 16 rifampin-resistant cultures (100, 93.8, and 100%, respectively), were correctly identified by line probe assay (LiPA), mismatch assay, and PhaB assay, respectively. Subsequently 38 sputa and bronchealveolar lavage specimens and 21 isolates were received from clinicians for molecular analysis. For the 38 primary specimens the LiPA and mismatch assay correlated with culture and subsequent identification and susceptibility tests in 36 and 38 specimens (94.7 and 100%), respectively. For the 21 isolates submitted by clinicians, both assays correlated 100% with routine testing.
Immobilization during anesthesia for vitrectomy using a laryngeal mask without neuromuscular blockade versus endotracheal intubation and neuromuscular blockade (2018)

For PPV, MAC adjusted balanced anesthesia using a laryngeal mask without neuromuscular blockade was associated with more, but clinically irrelevant upward eye deviations and may be an alternative to intubation with neuromuscular blockade. However, adequate depth of anesthesia must be assured to avoid unwanted injuries during surgery.
Quantum Critical Transition and Kondo Screening of Magnetic Moments in Graphene (2017)

In normal metals, the magnetic moment of impurity spins disappears below a characteristic Kondo temperature, TK, where coupling with the conduction-band electrons produces an entangled state that screens the local moment. In contrast, moments embedded in insulators remain unscreened at all temperatures. This raises the question about the fate of magnetic moments in intermediate, pseudogap systems, such as graphene. In these systems theory predicts a quantum phase-transition at a critical coupling strength which separates a local magnetic-moment phase from a Kondo screened phase. However, attempts to experimentally confirm these predictions and their intriguing consequences such as the ability to electrostatically control magnetic moments, have thus far been elusive. Here we report the observation of Kondo screening and the quantum phase-transition between screened and unscreened phases of vacancy magnetic-moments in graphene. Using scanning tunneling microscopy (STM), spectroscopy (STS) and numerical renormalization group (NRG) calculations, we identified Kondo screening by its spectroscopic signature and mapped the phase-transition as a function of coupling strength and chemical potential. We show that this transition makes it possible to turn the magnetic-moment on and off electrostatically through a gate voltage or mechanically through variations in local curvature.
