A Model for Efficient Consumer Pricing Schemes in Electricity Markets

Suppliers in competitive electricity markets regularly respond to prices that change hour by hour or even more frequently, but most consumers respond to price changes on a very different time scale, i.e., they observe and respond to changes in price as reflected on their monthly bills. In this paper, we examine mixed complementarity programming models of equilibrium that can bridge the speed of response gap between suppliers and consumers yet adhere to the principle of marginal cost pricing of electricity. We develop a computable equilibrium model to estimate ex ante time-of-use (TOU) prices for a retail electricity market. It is intended that the proposed models would be useful 1) for jurisdictions (e.g., Ontario) where consumers' prices are regulated, but suppliers offer into a competitive market, 2) for forecasting forward prices in unregulated markets, and 3) in evaluation and welfare analysis of the policies regarding regulated TOU pricing compared to regulated single pricing
A Search for Binary Systems among the Nearest L Dwarfs

We have used the Near-Infrared Camera and Multi-Object Spectrometer NIC1 camera on the Hubble Space Telescope to obtain high angular resolution images of 52 ultracool dwarfs in the immediate solar neighborhood. Nine systems are resolved as binary, with component separations from 1.5 to 15 AU. Based on current theoretical models and empirical bolometric corrections, all systems have components with similar luminosities and, consequently, high mass ratios, q > 0.8. Limiting analysis to L dwarfs within 20 pc, the observed binary fraction is 12%. Applying Bayesian analysis to our data set, we derive a mass-ratio distribution that peaks strongly at unity. Modeling the semimajor axis distribution as a logarithmic Gaussian, the best fit is centered at log a0 = 0.8 AU (∼6.3 AU), with a (logarithmic) width of ±0.3. The current data are consistent with an overall binary frequency of ∼24%.
Paclitaxel‐induced apoptosis in human gastric carcinoma cell lines

Gastric cancer is one of the most common cancers in Asia. Chemotherapy and radiation therapy have had limited success. Recently, paclitaxel has been found to be effective against a variety of cancers, including lung, breast, ovary, melanoma, and prostate. Whether paclitaxel is effective in the treatment of gastric cancer is not known and is worthy of investigation.
Canadian guidelines for body weight classification in adults: application in clinical practice to screen for overweight and obesity and to assess disease risk

Since 1985, the number of obese adults in Canada has doubled. [1][1] According to 2003 data from Statistics Canada ([www.statcan.ca/english/freepub/82-221-XIE/00604/tables/html/1228_03.htm][2]), 15% of adults are obese (body mass index [BMI] > 30 kg/m2) and 33% are overweight (BMI 25– 29.9 kg/ m2)

Protein packing: dependence on protein size, secondary structure and amino acid composition.

We have used the occluded surface algorithm to estimate the packing of both buried and exposed amino acid residues in protein structures. This method works equally well for buried residues and solvent-exposed residues in contrast to the commonly used Voronoi method that works directly only on buried residues. The atomic packing of individual globular proteins may vary significantly from the average packing of a large data set of globular proteins. Here, we demonstrate that these variations in protein packing are due to a complex combination of protein size, secondary structure composition and amino acid composition. Differences in protein packing are conserved in protein families of similar structure despite significant sequence differences. This conclusion indicates that quality assessments of packing in protein structures should include a consideration of various parameters including the packing of known homologous proteins. Also, modeling of protein structures based on homologous templates should take into account the packing of the template protein structure.
Disease Suppression on Greenhouse Tomatoes Using Plant Waste Compost

Abstract This study investigated the disease suppression abilities of a compost amendment that was added to the conventional growing medium, yellow cedar sawdust, used in most British Columbia vegetable greenhouses. The compost amendment was produced in a controlled, in-vessel process primarily from greenhouse crop waste materials. The pathogen and cultivar under study were Fusarium oxysporumf. sp. radicis-lycopersici (FORL) on Dombito (FORL-susceptible) beefsteak greenhouse tomatoes. Significant reduction of Fusarium crown and root rot was also realized in tomato seedlings by applying compost amendment from several different batches, as a seed cover or plug substitute. In a greenhouse trial, disease suppression using a mixture of 2:1 sawdust to amendment by volume was shown to be most effective. As a result, the tomato yield over a nine-month growing season was improved by 74% where the medium was deliberately infested with FORL.
Mapping of Quantitative Trait Loci Determining NK Cell-Mediated Resistance to MHC Class I-Deficient Bone Marrow Grafts in Perforin-Deficient Mice1

NK cells reject allogeneic and MHC class I-deficient bone marrow (BM) grafts in vivo. The mechanisms used by NK cells to mediate this rejection are not yet thoroughly characterized. Although perforin plays a major role, perforin-independent mechanisms are involved as well. C57BL/6 mice deficient in perforin (B6 perforin knockout (PKO)) reject class I-deficient TAP-1 KO BM cells as efficiently as normal B6 mice. In contrast, perforin-deficient 129S6/SvEvTac mice (129 PKO) cannot mediate this rejection while normal 129 mice efficiently reject. This suggests that in 129, but not in B6, mice, perforin is crucial for NK cell-mediated rejection of MHC class I-deficient BM grafts. To identify loci linked to BM rejection in perforin-deficient mice, we generated backcross 1 progeny by crossing (129 × B6)F1 PKO mice to 129 PKO mice. In transplantation experiments, >350 backcross 1 progeny were analyzed and displayed a great variation in ability to reject TAP-1 KO BM grafts. PCR-based microsatellite mapping identified four quantitative trait loci (QTL) on chromosomes 2, 4, and 8, with the QTL on chromosome 8 showing the highest significance, as well as a fifth epistatic QTL on chromosome 3. This study describes the first important step toward identifying BM graft resistance gene(s).
Robotic exploration of surfaces and its application to legged locomotion

It is noted that material properties like penetrability, compliance, and surface roughness are important in the characterization of the environment. The authors have designed and implemented exploratory procedures on a robotic system to actively explore a surface to extract its material properties. The exploratory procedures for exploration are integrated into an active perceptual scheme for legged locomotion. The perceptual scheme is designed around creating the ability for the robot to sense variations in terrain properties while it is walking, so that it may be able to avoid sinking, slipping, and falling due to unexpected changes in the terrain properties, and make suitable changes in its foot forces to continue locomotion. The active perceptual scheme is implemented by simulating a leg-ankle-foot system with a PUMA arm-compliant wrist-foot system and an accelerometer mounted on the foot to detect slip. <<ETX>>
River valleys and foothills: changing archaeological perceptions of North China's earliest farms

Abstract Early farming in northern China featured the cultivation of two species of millet, broomcorn and foxtail. Although previously seen as focused on the Yellow River, the authors show that the earliest agriculture is actually found in the foothills of the neighbouring mountain chains, where drier and better drained locations suited millet cultivation, particularly broomcorn. In this they echo new thoughts on the locale of early agriculture in south-west Asia, on the hilly flanks of the Fertile Crescent rather than in the valleys of the Nile or the Euphrates.
Playing by Unfair Rules? Asia's Positioning within Global Sports Production Networks

The link between global sports brands and the violation of workers' rights in Asia has been a mainstream issue for many years. A ceaseless flow of news reports on the infringement of workers' rights in Asia suggests that neocolonialist dependencies and the ruthless exploitation of sweatshop labor are endemic in the industry. However, Asian corporations standing in the shadow of global brands have recently taken the lead in coordinating global sports commodity chains. Asia's rise within the industry is having manifold impacts on development opportunities for workers, companies, and countries, first of all in the Asian region, but also beyond. Putting these transformations into the historical perspective of industrialization, this essay questions the taken-for-granted assumption about agency and compliance behind the new international division of labor.
New classification of pancreatic intraductal papillary–mucinous tumour by mucin expression: its relationship with potential for malignancy

In previous studies of the expression of MUC1 (membrane‐bound type mucin) and MUC2 (intestinal type secretory mucin) in pancreatic tumours, invasive ductal carcinoma (IDC) usually showed MUC1+ and MUC2− expression, whereas intraductal papillary–mucinous tumour (IPMT) showed MUC1− and MUC2+ expression. Recently, however, many IPMTs have been collected, a considerable number of which have shown MUC1− and MUC2− expression. In the present study, the clinicopathological features were examined of 18 IPMTs with MUC2+ and 32 IPMTs with MUC2−, and their potential for malignancy was compared. Most of the IPMTs with MUC2+ were composed of dark columnar cells, whereas most of the IPMTs with MUC2− were composed of clear columnar cells. The incidence of carcinomatous change and invasive proliferation of the carcinoma in the MUC2+ tumours was significantly higher than in the MUC2− tumours. The clinical outcome for the patients with IPMT showing the MUC2+ pattern tended to be worse than for those with IPMT showing the MUC2− pattern, although the overall outcome for the two types of IPMT was significantly better than for those with IDC. Because of the differences in mucin expression pattern, morphological appearance and potential for malignancy between the two types of IPMT, we believe that they belong to different neoplastic lineages and that it may be reasonable to classify them as different entities, although the WHO classification contains a single clinicopathological entity of IPMT forming an adenoma–carcinoma sequence. In conclusion, our classification of IPMTs by MUC2 expression pattern may be of value in the better assessment of the biological behaviour of IPMTs and their potential for malignancy.

Primary Reading Epilepsy: Investigation of Critical Seizure‐Provoking Stimuli

Summary: Precipitating stimuli were investigated in a 24‐year‐old woman with primary reading epilepsy. Reading material was presented on a microcomputer video display monitor under controlled conditions while the patient underwent EEG radiotelemetry/video monitoring. We examined the relative contribution of the following variables utilizing a factorial design: eye movements, reading aloud versus reading silently, linguistic complexity, and concentration. None of these factors acted solely as the critical stimulus in provoking seizures. Seizures were most readily elicited when the patient read aloud, using material of medium or high linguistic complexity with the usual scanning eye movements for reading.
IMMUNOGLOBULINS OF THE GERMFREE GUINEA PIG.

Determinations of the total serum γ-globulin by a number of immunochemical techniques confirms that the non-germfree guinea pig has up to 6 times more γ-globulin than the germfree guinea pig. A similar relationship exists between the serum 7 S γ2-globulins and 19 S γ-macroglobulins of germfree and non-germfree guinea pigs. However, the serum 7 S γ1-globulins do not conform to this pattern. One group of germfree guinea pigs has approximately one half the serum γ1-globulin of the non-germfree animals, but a second group of germfree guinea pigs has approximately twice as much γ1-globulin as the non-germfree animals. The published determinations of γ-globulin in the sera of the guinea pig and other species reared germfree have been reviewed. The differences between the serum γ-globulin concentrations of germfree and normal animals are better demonstrated by the use of quantitative techniques sensitive and accurate at low serum γ-globulin levels and specific for γ-globulin. Quantitative precipitation gave accurate results at both low and normal serum levels. Hemagglutination inhibition and simple gel diffusion gave accurate values at low serum γ-globulin levels, but gave higher values than quantitative precipitin and paper electrophoresis at normal levels. Results obtained by double-diffusion-in-agar were generally not in close agreement with those obtained by other methods. In general, electrophoretic methods were relatively inaccurate and nonspecific for quantitation of low levels, when compared to the quantitative immunochemical methods, but were accurate at normal levels.
Spatial Modeling of Thin-Film Solar Modules Using the Network Simulation Method and SPICE

The use of the network simulation method (NSM) for the modeling of thin-film solar modules is discussed. It will be shown that for the accurate modeling of small defects using the NSM, a variable mesh is required to keep the computation time within reasonable limits. A simulation tool for thin-film solar modules is developed that implements the NSM with a variable, adaptive mesh. The results of this model will be compared with electroluminescence experiments on a Cu(In,Ga)Se2 solar module with a defect (shunt). Furthermore, it is demonstrated that the program can handle complex-shaped inhomogeneities such as local variations in solar cell properties, illumination, and contact layer resistance.

A Hybrid Quantum Evolutionary Algorithm

This paper proposes a Hybrid Quantum Evolutionary Algorithm. Quantum computing is capable of processing huge numbers of quantum states simultaneously, in parallel, (“quantum parallelism”), whereas evolutionary computing can only process one chromosome per processor. In theory, QC ought to be able to process upto all possible points in a 2 search space (of N bit chromosomes). An evolutionary algorithm is effectively a guided search algorithm that samples the search space and in general is a slow process. Since QC can examine all or some of 2 points simultaneously, this Quantum Parallelism can be cleverly used to speed the Evolutionary Algorithms. This paper presents a Hybrid Quantum Evolutionary Algorithm that uses the Quantum Parallelism and an other well-known Quantum Algorithm to speed up the Evolutionary Algorithms.
Solving economic load dispatch problem using hybrid Krill Herd algorithm

This paper proposes an effective hybrid Krill Herd algorithm to solve Economic Load Dispatch problems. Effects of valve-point loading, prohibited operating zones of thermal plants are studied. System transmission losses as well as various equality and inequality operational constraints have also been considered. Numerical results exhibit that the proposed technique, involving crossover and mutation operators, is able to provide better solution than several techniques present in the literature, in terms of generation cost. Furthermore, this algorithm is better in terms of robustness than most of the existing algorithms used for this study.
All New Faces of Diatoms: Potential Source of Nanomaterials and Beyond

Nature’s silicon marvel, the diatoms have lately astounded the scientific community with its intricate designs and lasting durability. Diatoms are a major group of phytoplanktons involved in the biogeochemical cycling of silica and are virtually inherent in every environment ranging from water to ice to soil. The usage of diatoms has proved prudently cost effective and its handling neither requires costly materials nor sophisticated instruments. Diatoms can easily be acquired from the environment, their culture requires ambient condition and does not involve any costly media or expensive instruments, besides, they can be transported in small quantities and proliferated to a desirable confluence from that scratch, thus are excellent cost effective industrial raw material. Naturally occurring diatom frustules are a source of nanomaterials. Their silica bio-shells have raised curiosity among nanotechnologists who hope that diatoms will facilitate tailoring minuscule structures which are beyond the capabilities of material scientists. Additionally, there is a colossal diversity in the dimensions of diatoms as the frustule shape differs from species to species; this provides a scope for the choice of a particular species of diatom to be tailored to an exacting requisite, thus paving the way to create desired three dimensional nanocomposites. The present article explores the use of diatoms in various arenas of science, may it be in nanotechnology, biotechnology, environmental science, biophysics or biochemistry and summarizes facets of diatom biology under one umbrella. Special emphasis has been given to biosilicification, biomineralization and use of diatoms as nanomaterials’, drug delivery vehicles, optical and immune-biosensors, filters, immunodiagnostics, aquaculture feeds, lab-on-a-chip, metabolites, and biofuels.

Autoimmune hypocalciuric hypercalcemia unresponsive to glucocorticoid therapy in a patient with blocking autoantibodies against the calcium-sensing receptor.

CONTEXT Autoantibodies directed against the calcium-sensing receptor (CaSR) have been reported in several individuals with various autoimmune disorders and PTH-mediated hypercalcemia. Previously, glucocorticoid treatment has been shown to decrease the CaSR autoantibody titers and normalize the hypercalcemia in a patient with autoimmune hypocalciuric hypercalcemia (AHH). OBJECTIVE The objective of the study was to evaluate a patient with AHH for the presence of blocking autoantibodies against the CaSR and to monitor her biochemical and serological responses to a trial of glucocorticoid therapy. RESULTS Glucocorticoid treatment had no effect on serum total or ionized calcium concentration or serum PTH levels, all of which remained at higher than normal levels. In contrast, on prednisone, urinary calcium excretion increased from overtly hypocalciuric levels to normal values. Anti-CaSR autoantibodies were detected at similar levels in the patient's serum before, during, and after glucocorticoid treatment. Functional testing of these antibodies showed that they inhibited the stimulatory effect of extracellular Ca(2+) on ERK1/2 but did not suppress the calcium-induced accumulation of inositol-1-phosphate. CONCLUSIONS We report a patient with AHH with frankly elevated PTH levels who was found to have autoantibodies against the CaSR. The hypercalcemia and CaSR autoantibody titers failed to respond to glucocorticoid therapy, unlike a previously reported patient with similar clinical and biochemical features. The anti-CaSR antibody-mediated inhibition of CaSR-stimulated ERK1/2 activity, but not of inositol-1-phosphate accumulation, suggests that ERK1/2 may mediate, at least in part, the regulation of PTH secretion and urinary calcium excretion by the CaSR.
Hall Effects on Magnetic Relaxation

A generalized vorticity is introduced whose self-linkage (the hybrid helicity) and flux are invariants of ideal incompressible magnetohydrodynamics (MHD) when the Hall term is included. A model of magnetofluid relaxation is constructed for Hall magnetohydrodynamics by assuming that the energy seeks the minimum value compatible with constrained values of magnetic helicity, hybrid helicity, axial magnetic flux, and fluid vorticity flux. As a result of the coupling of magnetic field to fluid vorticity in the generalized vorticity, it is found that the relaxed magnetic-field configuration need not be force free. The presence of a nonvanishing fluid vorticity is shown to be necessary for the existence of relaxed magnetic-field configurations that confine a finite plasma pressure. The study has potential relevance to the dynamics and morphology of space and cosmic plasmas, as well as to pressure confinement and current drive in fusion plasmas.
