Spinel and Perovskite Functional Layers Between Plansee Metallic Interconnect (Cr-5 wt % Fe-1 wt % Y[sub 2]O[sub 3]) and Ceramic (La[sub 0.85]Sr[sub 0.15])[sub 0.91]MnO[sub 3] Cathode Materials for Solid Oxide Fuel Cells (2000)

The degradation of the interface between Plansee Ducrolloy alloy (Cr‐5 wt % Fe‐1 wt % ) (PD) and (LSM) ceramic was studied by means of electrical resistance measurements at 900°C in air humidified with 2% and with a dc load of and by scanning electron microscopy/energy‐dispersive spectroscopy of cross sections of the samples. One sample of PD alloy with plasma‐sprayed and a contacting layer of exhibited little degradation, estimated to be after 10,000 h. Other samples of PD were coated by different spinel‐forming slurries pretreated in mixtures at 950 and 1000°C. Coatings forming spinel and using as a contacting layer showed a low estimated degradation of after 10,000 h. Another spinel appeared to reduce Cr diffusion significantly, and when used together with a mixed perovskite made of 1:1 of LSM and as a contacting layer, exhibited estimated degradation of for 10,000 h. © 2000 The Electrochemical Society.

Intermonomer Interactions in Hemagglutinin Subunits HA1 and HA2 Affecting Hemagglutinin Stability and Influenza Virus Infectivity (2015)

Influenza virus hemagglutinin (HA) is the principal antigen in inactivated influenza vaccines and the target of protective antibodies. However, the influenza A virus HA is highly variable, necessitating frequent vaccine changes to match circulating strains. Sequence changes in HA affect not only antigenicity but also HA stability, which has important implications for vaccine production, as well as viral adaptation to hosts. HA from the pandemic 2009 H1N1 influenza A virus is less stable than other recent seasonal influenza virus HAs, but the molecular interactions that contribute to HA stability are not fully understood. Here we identify molecular interactions between specific residues in the surface and transmembrane subunits of HA that help regulate the HA conformational changes needed for HA stability and virus entry. These findings contribute to our understanding of the molecular mechanisms controlling HA function and antigen stability.
GYNAECOLOGY FROM ANCIENT EGYPT: THE PAPYRUS KAHUN A TRANSLATION OF THE OLDEST TREATISE ON GYNAECOLOGY THAT HAS SURVIVED FROM THE ANCIENT WORLD (1975)

This article presents a new translation of the papyrus Kahun. Interest in the papyrus lies in its being indisputably the most ancient document on gynaecology known. The text consists of a continuum of individual "cases" which lend themselves to subdivsion into four major sections. Selected commentaries accompany the translation which consist in the main of illuminating quotations from other Egyptian papyri. The aim is to propagate some insight into the gynaecological concepts behind medical practice around 2000 B.C.
Modeling Individual's Movement Patterns to Infer Next Location from Sparse Trajectory Traces (2018)

Human mobility prediction is a challenging and crucial task for fostering wide spectrum of location based applications, namely, traffic planning, travel-plan recommendation etc. However, modeling human movement behaviour and predicting next location are non-trivial tasks. We consider the human mobility pattern modeling and predicting next location problem for semantic trajectory data, wherein sparse GPS records are associated with other contextual information. Intuitively, human moves with an intent and the confluence of movement history (GPS traces) and contextual information may help in capturing people's intents at a fine granularity and has potential to improve the efficacy of location prediction problem. In this paper, a hierarchical and layered hidden markov model (HMM) framework for mobility prediction from sparse trajectories has been proposed. Experiment on real-life mobility dataset of Nokia Mobile Data Challenge (MDC) demonstrates the efficacy of the proposed framework even when with sparse GPS traces.
Evaluation of STAT-CRIT?? Hematocrit Determination in Comparison to Coulter and Centrifuge (1993)

The accuracy of the STAT-CRIT hematocrit (hct) was compared to Coulter and centrifuge methods in this study of the interrelationship between non-red cell blood constituents and accuracy of conductivity-based hct measurements. In the first part of the study, blood samples from 31 patients undergoing elective cardiac procedures were analyzed at three times: before induction of anesthesia (Time 1), during the rewarming period of cardiopulmonary bypass (CPB) (Time 2), and after transfusion of all cell-saver blood available after termination of CPB (Time 3). Laboratory evaluation included hct using the Stat-Crit, Coulter, and centrifuge methods, and sodium (Na), potassium (K), chloride (Cl), white blood cell count, total protein (TP), and albumin. In the second part of the study, patients were randomized to receive either 5% albumin (n = 14) or isotonic crystalloid (n = 14) after termination of CPB to determine the effect of protein colloid replacement on conductivity-based hct measurements. Blood samples were obtained before and after fluid volume replacement for multivariate analysis. Correlation of Coulter hct (absolute) with microhematocrit by centrifuge at all times (n = 93) was 0.95 (R2) with a bias and precision of -0.26 +/- 1.7%. Blood variables having the most significant effect on the Coulter-Stat-Crit difference (bias) were protein, Cl, and Na. Single regression analysis indicated that a 1-g/dL decrease in TP resulted in an absolute decrease in the hct reading by 1 hct% units. A 10-mmol/L change in either Cl or Na concentration resulted in a change in Stat-Crit accuracy of 3.5% and 2.5%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
Successful field tests of a multi-process phytoremediation system for decontamination of persistent petroleum and organic contaminants (2006)

A large number of aquatic and terrestrial environments are polluted with various levels of toxicants. Metals, organics and total petroleum hydrocarbons from anthropogenic sources pose a risk to both human health and the health of ecosystems. Although these persistent contaminants are difficult to remediate, several industrial sites throughout North America are being remediated as part of land reclamation and restoration programs. This paper addressed the issue of phytoremediation for removing contaminants from soils. Phytoremediation is considered to be a viable remediation strategy because the increased biomass of plants, relative to the biomass of soil microbes in the absence of plants, allows for higher throughput. Extensive root systems can infiltrate large volumes of soil, thus promoting degradation of contaminants over a wide area. This paper described a newly developed multi-process phytoremediation system with accelerated remediation kinetics to effectively remove polycyclic aromatic hydrocarbons (PAH), total petroleum hydrocarbons (TPH) and chlorinated hydrocarbons (CHC) from soils. The system combines land farming/sunlight exposure; inoculation of contaminant degrading bacteria; and, plant growth with plant growth promoting rhizobacteria which mitigates the effects of stress ethylene in plants. The primary factor for success was the interaction between the plant and the plant growth promoting rhizobacteria. Several field tests were conducted following successful greenhouse tests. Results at a TPH contaminated site in Sarnia, Ontario showed that over a 2 year period, 60 to 70 per cent remediation of 15 per cent TPH was achieved. At a site in Turner Valley, Alberta, 35 per cent remediation of 1 per cent recalcitrant TPH was achieved, while a DDT contaminated site near Simcoe, Ontario had nearly 30 per cent of CHC removed in a 3 month period. 34 refs., 2 tabs., 2 figs.
Droplet Motion on Designed Microtextured Superhydrophobic Surfaces with Tunable Wettability (2008)

Superhydrophobic surfaces have shown promising applications in microfluidic systems as a result of their water-repellent and low-friction properties over the past decade. Recently, designed microstructures have been experimentally applied to construct wettability gradients and direct the droplet motion. However, thermodynamic mechanisms responsible for the droplet motion on such regular rough surfaces have not been well understood such that at present specific guidelines for the design of tunable superhydrophobic surfaces are not available. In this study, we propose a simple but robust thermodynamic methodology to gain thorough insight into the physical nature for the controllable motion of droplets. On the basis of the thermodynamic calculations of free energy (FE) and the free-energy barrier (FEB), the effects of surface geometry of a pillar microtexture are systematically investigated. It is found that decreasing the pillar width and spacing simultaneously is required to lower the advancing and receding FEBs to effectively direct droplets on the roughness gradient surface. Furthermore, the external energy plays a role in the actuation of spontaneous droplet motion with the cooperation of the roughness gradient. In addition, it is suggested that the so-called "virtual wall" used to confine the liquid flow along the undesired directions could be achieved by constructing highly advancing FEB areas around the microchannels, which is promising for the design of microfluidic systems.
Gut Hormones: A Weight Off Your Mind (2008)

The increasing prevalence of obesity and the associated morbidity and mortality has resulted in a major research effort to identify mechanisms that regulate appetite. It is well established that the hypothalamus and brain stem are major sites in the central nervous system (CNS) that regulate appetite. Until recently the missing element has been how information regarding food intake and energy stores is communicated to the CNS. Gut hormones have recently been found to be an important element in this regulation, communicating information regarding food intake to the CNS. Several gut hormones have been found to exert anorectic effects. These include members of the Pancreatic Polypeptide (PP)-fold family, namely PP itself and also peptide tyrosine-tyrosine (PYY), the first gut hormone shown to have appetite-inhibiting properties. The other main class of anorectic gut hormones are those derived by proteolytic processing from proglucagon, most importantly glucagon-like peptide-1 (GLP-1) and oxyntomodulin. All of these are currently being investigated as the basis of treatments to prevent the development of obesity. So far the only gastrointestinal hormone demonstrated to stimulate appetite is ghrelin. Potential sites and mechanisms of action and therapeutic use of these gastrointestinal hormones are discussed.
Polarimetric Imaging for the Detection of Disturbed Surfaces (2009)

This work tested the ability of the fast time-division SALSA polarimetric camera of Bossa Nova Technologies, Ltd. to distinguish disturbed from undisturbed surfaces. Earth and asphalt were imaged, and the data was processed using standard ENVI software. The polarization signature of the disturbed earth was not strong, even when processing was employed. The camera was better able to distinguish between the polarization characteristics of patched or disturbed asphalt and the surrounding pavement, particularly when maximum likelihood classification was applied. The current results indicate that the camera needs to be systematically tested for sensitivity to roughness scale and soil type and that the asphalt results need to be further verified.
Embossing of high‐aspect‐ratio‐microstructures using sacrificial templates and fast surface heating (2007)

Abstract A new embossing method based on sacrificial templates and fast surface heating was developed, in which the de‐embossing step was avoided to prevent deformation or damage of polymer microstructures. The microstructures of interest have a high feature density, high aspect ratio, and/or undercuts. Soft lithography was used to prepare a water‐soluble mold, using polyvinylpyrrolidone (PVP) in the hot embossing process. Arrays of microchannels and microgrids with an aspect ratio greater than five were replicated on poly( DL ‐lactide‐ co ‐glycolide) (PLGA). In conjunction with localized surface heating of the polymer surface by a laser/IR system, this technique was able to micromold high temperature polymers such as poly(methyl methacrylate) (PMMA) with high aspect ratios.

Characterization of a whole blood assay for quantifying myeloid-derived suppressor cells (2019)

MDSC are a heterogenous group of cells, and their quantitation in WB can be affected by a number of pre-analytical variables. Consideration of these factors, and measurement using a material type that has not been manipulated, such as whole blood, is likely to yield the most accurate results.
Motor Planning, Not Execution, Separates Motor Memories (2016)

Recent theories of limb control emphasize motor cortex as a dynamical system, with planning setting the initial neural state, and execution arising from the self-limiting evolution of the intrinsic neural dynamics. Therefore, movements that share an initial trajectory but then diverge might have different neural states during the execution of the identical initial trajectories. We hypothesized that motor adaptation maps neural states to changes in motor command. This predicts that two opposing perturbations, which interfere when experienced over the same movement, could be learned if each is associated with a different plan even if not executed. We show that planning, but not executing, different follow-through movements allow opposing perturbations to be learned simultaneously over the same movement. However, no learning occurs if different follow throughs are executed, but not planned prior to movement initiation. Our results suggest neural, rather than physical states, are the critical factor associated with motor adaptation.
Trial of celecoxib in amyotrophic lateral sclerosis (2006)

At the dosage studied, celecoxib did not have a beneficial effect on research subjects with ALS, and it was safe. A biological effect of celecoxib was not demonstrated in the cerebrospinal fluid. Further studies of celecoxib at a dosage of 800 mg/day in ALS are not warranted.
The role of virtual noise in unconstrained frequency domain equalization (2005)

Decision feedback equalization is a popular method for signal detection that allows a good trade off between complexity and performance. The complexity of the decision feedback equalizer (DFE) is mainly concentrated in the feedforward filter, which is often realized in FIR form. When the number of taps of the FIR filter needed to obtain nearly optimal performance becomes large, one may take advantage of the efficiency of the FFT/IFFT algorithm realizing the feedforward filter in the discrete frequency domain. In this paper we consider the minimum mean square error (MMSE) DFE with feedforward filter in the discrete frequency domain, assuming perfect knowledge of a static channel. We move from the observation that the optimal MMSE-DFE feedforward filter is IIR, and point out that the classical scheme of unconstrained frequency domain filtering with overlap/save digital signal processing may induce substantial increase in the error rate when the approximation of the linear convolution between the received signal and the mentioned IIR, to a circular convolution is poor. Our main finding is that the error rate can be significantly improved by deliberately augmenting the power of the noise in the computation of the transfer function of the frequency domain feedforward filter.

The Relationship Between Generalized Resistance Resources, Sense of Coherence, and Health Among Finnish People Aged 65-69 (2005)

Abstract. The present study investigated the appropriateness of Antonovsky's model, in which generalized resistance resources (GRRs) facilitate an individual's sense of coherence (SOC); which in turn is assumed to sustain health. The proposed model was tested using a sample of 320 Finnish persons (132 of them were men and 188 women) aged 65-69 years. The GRRs investigated were family income, cognitive functioning, years of formal education, marital status, and physical exercise. Health was measured by means of a multidimensional indicator composed of physical, social and mental health. Structural Equation Modelling (SEM) within the framework of LISREL models were used to test the hypothesized model. The results showed that good cognitive functioning and physical activity in the whole sample, and marital status in men, were associated with a strong SOC, which in turn was positively related to physical, and especially, social and mental health.
Serializing Parallel Programs by Removing Redundant Computation (1994)

Programs often exhibit more parallelism than is actually available in the target architecture. This thesis introduces and evaluates three methods -- loop unrolling, loop common expression elimination, and loop differencing -- for automatically transforming a parallel algorithm into a less parallel one that takes advantage of only the parallelism available at run time. The resulting program performs less computation to produce its results; the running time is not just improved via second-order effects such as improving use of the memory hierarchy or reducing overhead (such optimizations can further improve performance). The asymptotic complexity is not usually reduced, but the constant factors can be lowered significantly, often by a factor of 4 or more. The basis for these methods is the detection of loop common expressions, or common subexpressions in different iterations of a parallel loop. The loop differencing method also permits computation of just the change in an expression from iteration to iteration.
Affinity-aware DMA buffer management for reducing off-chip memory access (2012)

It is well recognized that moving I/O data in/out memory has become critical for high bandwidth devices. Specifically, the embedded system, with limited cache size and simple architecture, consumes a large amount of CPU cycles for off-chip memory access. The work presented in this paper addresses this problem through an Affinity-aware DMA Buffer management strategy, called ADB, requiring no change to underlying hardware.
An inkjet-printed electrowetting valve for paper-fluidic sensors (2013)

Paper-fluidic devices have become an emerging trend for micro total analysis systems (microTAS) in the bioengineering field due to their ability to maintain the rapid, sensitive and specific attributes of microfluidic devices. Subsequently, paper-fluidic devices are also more portable, have a lower production cost and are easier to use. However, one of the obstacles in developing paper fluidic devices is the limited ability to control the rate of fluid flow during an assay. In our project, we use electrowetting on dielectrics where a dielectric, which is normally hydrophobic, is polarized and becomes hydrophilic. We have fabricated paper-fluidic devices by inkjet printing and spraying conductive hydrophobic electrodes/valves in conjunction with conductive hydrophilic electrodes which are able to stop the fluid front of phosphate buffered saline (PBS). The hydrophobic valves were then actuated by an applied potential which altered the fluorinated monolayer on the electrode. As the applied potential between the electrodes was increased, the amount of time for the fluid front to pass the valve decreased because the monolayer was altered faster. However, we did not observe significant differences in time as we increased the distance between the electrodes. The valves were also incorporated in a lateral flow assay where the device was used to detect Saccharomyces cerevisiae rRNA sequences. With the ability to control the fluid flow in a paper-fluidic device, more complex and intricate assays can be developed, which not only can be applied in the biomedical, food and environmental fields, but also can be used in low resource settings for the detection of diseases.
Increased survival of ischaemic musculocutaneous flaps in rats after acupuncture (1989)

The effects of acupuncture on survival of ischaemic musculocutaneous flaps were investigated in the rat. A dorsal cranially based standard flap (2 X 7 cm) was elevated and sutured back in position. The percentage survival of the flaps was estimated after 6 days. Manual acupuncture, electro-acupuncture but not superficial acupuncture significantly increased the survival of the flaps compared to untreated controls. The highest flap survival (92%) was obtained with repeated post-operative high-intensity electro-acupuncture. It is concluded that acupuncture treatment markedly increases experimental flap survival and may be of clinical importance for treatment of local ischaemia.
Origin, genetic diversity, and genome structure of the domestic dog (1999)

Comparative analysis of mammalian genomes provides important insight into the structure and function of genes. However, the comparative analysis of gene sequences from individuals of the same and different species also provides insight into the evolution of genes, populations, and species. We exemplify these two uses of genomic information. First, we document the evolutionary relationships of the domestic dog to other carnivores by using a variety of DNA-based information. A phylogenetic comparison of mitochondrial DNA sequences in dogs and gray wolves shows that dogs may have originated from multiple wolf populations at a time much earlier than suggested by the archaeologic record. We discuss previous theories about dog development and evolution in light of the new genetic data. Second, we review recent progress in dog genetic mapping due to the development of hypervariable markers and specific chromosome paints. Extensive genetic homology in gene order and function between humans and dogs has been discovered. The dog promises to be a valuable model for identifying genes that control morphologic differences between mammals as well as understanding genetically based disease.
