Demand Response of an Industrial Buyer considering Congestion and LMP in Day-Ahead Electricity Market
Authors: Jain Arvind Kumar 
Published: June 2019

AbstractThis paper proposes a methodology for developing Price Responsive Demand Shifting (PRDS) based bidding strategy of an industrial buyer, who can reschedule its production plan, considering power system network constraints. Locational Marginal Price (LMP) methodology, which is being used in PJM, California, New York, and New England electricity markets, has been utilized to manage the congestion. In this work, a stochastic linear optimization formulation comprising of two sub-problems has been proposed to obtain the optimal bidding strategy of an industrial buyer considering PRDS bidding. The first sub-problem is formulated as to maximize the social welfare of market participants subject to operational constraints and security constraints to facilitate market clearing process, while the second sub-problem represents the industrial buyer’s purchase cost saving maximization. The PRDS based bidding strategy, which is able to shift the demand, from high price periods to low price periods, has been obtained by solving two subproblems. The effectiveness of the proposed method has been tested on a 5-bus system and modified IEEE 30-bus system considering the hourly day-ahead market. Results obtained with the PRDS based bidding strategy have been compared with those obtained with a Conventional Price-Quantity (CPQ) bid. In simulation studies, it is observed that the PRDS approach can control the LMPs and congestion at the system buses. It is also found that PRDS can mitigate the market power by flattening the demand, which led to more saving and satisfying demand.

AbstractCongestion in the power system network is a threat to security, reliability, and economy of the power industry. Congestion management in deregulated power markets has become one of the significant tasks of system operators to address congestion in the transmission network. Many methods have been presented in literature with the aim of congestion management, improvement of the security and efficiency of the deregulated power market in the past few decades. This review paper explains various approaches/methods of congestion management in past few years and provides a comprehensive overview of congestion management methods. A comparative study was done among the different well known CM methods in this work. These methods were tested and analysed on modified 6-bus system, modified IEEE 14-bus system, and modified IEEE 30-bus system.

Deciding to Apply for Federal Disaster Assistance: A Preliminary Investigation of Disaster Decision-Making using a Bounded Rationality Framework
Authors: Rivera Jason D. 
Published: June 2019

AbstractAmong disaster victims, the decision to apply for assistance with the Federal Emergency Management Agency (FEMA) is not straight forward. It is typically affected a variety of factors beyond individual demographic characteristics. Using Texas in the aftermath of Hurricane Harvey, this study utilizes bounded rationality as a theoretical framework for exploring what may affect the decision to apply for individual assistance with FEMA. A representative sample of generally affected individuals and a subsample of individuals with home damage are used to investigate various factors thought to be important in decision-making and compare differences between the groups. As a byproduct of the analysis, it is observed that although the loss of employment and being able to rely on one’s immediate network is a significant predictor of applying for aid among individuals with home damage, these variables are not significant among those that were generally affected. Recommendations for future research are provided to enhance our understanding of decision-making in the aftermath of disasters.

Published: June 2019

AbstractEvaluation of genotypes under multiple environments is the prerequisite for the development of stable and superior genotypes for sustainable barley production and a changing climate. GGE (G, genotype and GE, genotype (G) by environment (E), interaction) biplot and the AMMI (The Additive Main effects and Multiplicative Interaction) model are the effective methods to find out the genotype(s) which are stable and suitable to cultivate in specific or multiple environments. The experiment was conducted to analyze the performance of seven barley genotypes for selecting stable and superior genotypes across three different environmental conditions of Bangladesh (i.e., at the Bangladesh Agricultural Research Institute (BARI), Gazipur; at the Regional Agricultural Research Station (RARS), BARI, Jamalpur and at the RARS, BARI Ishurdi). All genotypes in three locations were arranged in a randomized complete block design (RCBD) with three replications. After two years observation, it was found that all genotypes across the location were found highly significant (p≤0.01), due to the variation of environments, genotypic variability and their interaction. The first two principle component axes (PC1 and PC2) of site regression model were significant (P≤0.01) and cumulatively contributed to 89.65% of the total GE interaction. In the polygon view of biplot, there were five rays which divided the biplot into five sectors, and all three locations fell into two of these five sections. Location Jamalpur fell into sector 1, whereas Ishurdi and Gazipur fell into sector 2. Among the locations, Ishurdi was found the best for all genotypes, where Gazipur and Jamalpur were found unfavourable. Among the genotypes, ‘E7’ performed the best for the average grain yield (GY) followed by ‘E3’, ‘E2’ and ‘E4’, whereas ‘E1’ had lowest average GY for all locations. The highest yield in environment Jamalpur was obtained by the genotype ‘E2’, on the other hand genotype ‘E7’ produced the highest GY in locations of Ishurdi and Gazipur. Considering yield stability, genotypes ‘E3’, ‘E4’ and ‘E1’ were found to be more stable, whereas genotype ‘E2’ was the most unstable over all locations. Genotypes ‘E7’ and ‘E3’ were found to be close to the ideal genotype position, in the case of the maximum GY and yield stability across the locations as compared to other genotypes and recommended for commercial cultivation for Bangladesh including South-Asia.
The theory of synesthesia according to the Pythagorean tradition and Nabokov’s revisiting of Pythagorean synesthesia
Authors: Dureau Yona 
Published: June 2019

Abstract
In Ancient times, synesthesia was a form of perception sought after, as developed both by Pythagoras and by Aristotle. It was a degree of perception sought after for the perception of the divine. It was part of a definite aesthetics because art was supposed to permit access to synesthesia through very precise rules defined by Aristotle in his Rhetoric. Synesthesia was not an anomalous form of perception experienced by some writers only. It was supposed to be induced by certain masterpieces, thus connecting the reader’s experience of synesthesia with the writer’s. The hypothesis of the present paper is that Nabokov knew those theories and that his knowledge of Ancient sources was not limited to Plato whom he quotes repeatedly in his interviews, but also comprised Aristotle. Not only did Nabokov know about that theory, some interviews, and some of his novels reveal a game with those sources and a quest for the reader’s synesthesia. The present article focuses on the two first pages of The Gift as a skillful implementation of Aristotle’s theory on synesthesia.
Stress and Vibration Analysis of a PDC (Pulse Detonation Chamber)

Published: June 2019

Abstract
Pulse detonation engines work similar to pulsejets, with the major difference taking place in the combustion mechanism. Having detonation, instead of conventional combustion comes with certain benefits, but also, a couple of major issues which will be addressed in this paper. These changes come as a result of the increased amount of energy released by the explosive process, with much higher fluid velocities and temperatures that easily surpass those of conventional engines. These high values of the thermodynamic parameters prove to be a tough technological problem when it comes to producing this type of engines, so this paper aims at analyzing the evolution of these parameters throughout a working cycle of the Tangential Impulse Detonation Engine (TIDE) and how they affect the internal structure of the detonation chamber. The non-steady character of the thermodynamic parameters from a Computational Fluid Dynamics (CFD) simulation will be used a as a starting point for the Finite Element Analysis (FEA), which will help determine whether or not, the structure can withstand the immense load that comes with such violent processes. The final part of this article will provide optimization criteria to decrease the loads generated by the pulsed detonations.
Postnatal Increases in Axonal Conduction Velocity of an IdentifiedDrosophilaInterneuron Require Fast Sodium, L-Type Calcium and Shaker Potassium Channels
Authors: Kadas Dimitrios , Duch Carsten , Consoulas Christos 
Published: June 2019

AbstractDuring early postnatal life, speed up of signal propagation through many central and peripheral neurons has been associated with an increase in axon diameter or/and myelination. Especially in unmyelinated axons postnatal adjustments of axonal membrane conductances is potentially a third mechanism but solid evidence is lacking. Here, we show that axonal action potential (AP) conduction velocity in theDrosophilagiant fiber (GF) interneuron, which is required for fast long-distance signal conduction through the escape circuit, is increased by 80% during the first day of adult life. Genetic manipulations indicate that this postnatal increase in AP conduction velocity in the unmyelinated GF axon is likely owed to adjustments of ion channel expression or properties rather than axon diameter increases. Specifically, targeted RNAi knock-down of either Para fast voltage-gated sodium, Shaker potassium (Kv1homologue), or surprisingly, L-type like calcium channels counteracts postnatal increases in GF axonal conduction velocity. By contrast, the calcium-dependent potassium channel Slowpoke (BK) is not essential for postnatal speeding, although it also significantly increases conduction velocity. Therefore, we identified multiple ion channels that function to support fast axonal AP conduction velocity, but only a subset of these are regulated during early postnatal life to maximize conduction velocity. Despite its large diameter (∼7 µm) and postnatal regulation of multiple ionic conductances, mature GF axonal conduction velocity is still 20–60 times slower than that of vertebrate Aβ sensory axons and α motoneurons, thus unraveling the limits of long-range information transfer speed through invertebrate circuits.

Authors: Guarnotta V , Di Stefano C , Santoro A , Ciresi A , Coppola A , Giordano C 
Published: June 2019

Background
Dual-release hydrocortisone (DR-HC) improves metabolism in patients with adrenal insufficiency. The aims of this study were to compare the cardiovascular and metabolic effects of conventional glucocorticoids (GCs) vs. DR-HC and of high vs. low doses of GCs, after 48 months of observation.

Methods
We selected 27 patients on hydrocortisone (mean dose 17.5 ± 4.2 mg/day) and 20 patients on cortisone acetate (mean dose 37.5 ± 12.1 mg/day) who maintained this treatment (group A) and 53 patients switched to DR-HC (mean dose 22 ± 4.8 mg/day) (group B). At baseline and after 48 months, clinical and metabolic parameters and Framingham Risk Score (FRS) were obtained.

Results
After 48 months, patients in group A had a significant increase from baseline in BMI (P < 0.001), waist circumference (P = 0.001), systolic blood pressure (P = 0.001), LDL cholesterol (P = 0.018), HbA1c (P = 0.020) and FRS (P = 0.002). By contrast, patients in group B had a significant decrease in BMI (P = 0.002), waist circumference (P = 0.015), diastolic blood pressure (P = 0.031), total (P = 0.006) and LDL cholesterol (P = 0.005), HbA1c (P < 0.001) and FRS (P = 0.015) compared to baseline. No significant differences between high and low doses of both conventional GCs and DR-HC were observed.

Conclusions
DR-HC is associated with an improvement of metabolic parameters and cardiovascular risk compared to conventional GCs, which are associated with a worsening of these parameters, regardless of the dose used.
Heritability in Plant Breeding on a Genotype-Difference Basis
Authors: Schmidt Paul , Hartung Jens , Bennewitz Jörn , Piepho Hans-Peter 
Published: June 2019

Abstract
In plant breeding, heritability is often calculated (i) as a measure of precision of trials and/or (ii) to compute the response to selection. It is usually estimated on an entry-mean basis, since the phenotype is usually an aggregated value, as genotypes are replicated in trials, which stands in contrast with animal breeding and human genetics. When this was first proposed, assumptions such as balanced data and independent genotypic effects were made that are often violated in modern plant breeding trials/analyses. Due to this, multiple alternative methods have been proposed, aiming to generalize heritability on an entry-mean basis. In this study, we propose an extension of the concept for heritability on an entry-mean to an entry-difference basis, which allows for more detailed insight and is more meaningful in the context of selection in plant breeding, because the correlation among entry means can be accounted for. We show that under certain circumstances our method reduces to other popular generalized methods for heritability estimation on an entry-mean basis. The approach is exemplified via four examples that show different levels of complexity, where we compare six methods for heritability estimation on an entry-mean basis to our approach (example codes: https://github.com/PaulSchmidtGit/Heritability). Results suggest that heritability on an entry-difference basis is a well-suited alternative for obtaining an overall heritability estimate, and in addition provides one heritability per genotype as well as one per difference between genotypes.

Significance Statement
The NaCl cotransporter NCC in the kidney distal convoluted tubule (DCT) regulates urinary NaCl excretion and BP. The long-term effects of the mineralocorticoid aldosterone on modulating NaCl reabsorption via NCC are well established, and their importance illustrated by the effects of NCC-targeting diuretics and the salt-wasting observed in Gitelman syndrome. In this study the authors demonstrate that aldosterone also has rapid effects on the DCT, partly via the membrane receptors EGFR and GPR30. Signaling from these receptors affect NCC activity so that when aldosterone is released in response to hypovolemia, aldosterone rapidly increases NaCl reabsorption to help restore blood volume.

Background
The NaCl cotransporter NCC in the kidney distal convoluted tubule (DCT) regulates urinary NaCl excretion and BP. Aldosterone increases NaCl reabsorption via NCC over the long-term by altering gene expression. But the acute effects of aldosterone in the DCT are less well understood.

Methods
Proteomics, bioinformatics, and cell biology approaches were combined with animal models and gene-targeted mice.

Results
Aldosterone significantly increases NCC activity within minutes in vivo or ex vivo. These effects were independent of transcription and translation, but were absent in the presence of high potassium. In vitro, aldosterone rapidly increased intracellular cAMP and inositol phosphate accumulation, and altered phosphorylation of various kinases/kinase substrates within the MAPK/ERK, PI3K/AKT, and cAMP/PKA pathways. Inhibiting GPR30, a membrane-associated receptor, limited aldosterone’s effects on NCC activity ex vivo, and NCC phosphorylation was reduced in GPR30 knockout mice. Phosphoproteomics, network analysis, and in vitro studies determined that aldosterone activates EGFR-dependent signaling. The EGFR immunolocalized to the DCT and EGFR tyrosine kinase inhibition decreased NCC activity ex vivo and in vivo.

Conclusions
Aldosterone acutely activates NCC to modulate renal NaCl excretion.
