Equilibrium analysis in imperfect Traders' and GenCos' market

The paper models the strategic behavior of traders, GenCos and ISO using the multi-leader-follower framework. The outcomes of the strategic behavior of the players have been modeled using an equilibrium problem with equilibrium constraints. From a policy perspective it is seen that allowing the GenCos to hold FTRs may be welfare enhancing under certain demand conditions and ownership patterns of transmission rights and generation assets. The proposed model has been simulated on a 3 bus system. © 2010 IEEE.published_or_final_versionThe IEEE/PES Transmission and Distribution Conference and Exposition, New Orleans, LA., 19-22 April 2010.

Graph Contrastive Learning for Multi-omics Data

Advancements in technologies related to working with omics data require novel computation methods to fully leverage information and help develop a better understanding of human diseases. This paper studies the effects of introducing graph contrastive learning to help leverage graph structure and information to produce better representations for downstream classification tasks for multi-omics datasets. We present a learnining framework named Multi-Omics Graph Contrastive Learner(MOGCL) which outperforms several aproaches for integrating multi-omics data for supervised learning tasks. We show that pre-training graph models with a contrastive methodology along with fine-tuning it in a supervised manner is an efficient strategy for multi-omics data classification

INFORMATIONAL CONTENT OF IMPLIED AND HISTORICAL VOLATILITY DURING SUB-PRIME CRISIS

The initial paper had concluded that implied volatility is not a good predictor of the realized volatility, and instead historical volatility does a better job of explaining the realized volatility. Based on our findings from the data during the subprime crisis, we observe that both implied volatility and historical volatility are not efficient predictors of future volatility, but when compared, implied volatility does a better job than historical volatility. Our findings differ from the original research as we used a different time-period, and the findings are in line with logical reasoning as during periods of high volatility, historical volatility does not give any prediction of future volatility as circumstances change drastically

Oligopolistic competition of gencos in reactive power ancillary service provisions

The need for a market based approach for reactive power procurement has been recognized by FERC. Due to the localized characteristic of reactive power, regulatory mechanisms are necessary to mitigate the possibility of holding market power by generators. The regulator is responsible for devising the regulatory mechanisms that provide incentives to generators to supply reactive power while preventing the abuse of market power. This paper proposes a mathematical model to simulate the strategic behavior of generators supplying reactive power while considering the system operator's schedule. The proposed method can be used by the regulator to simulate the market behavior in the reactive power supply. We further study how regulatory policies affect the strategic behavior. An alternative price cap method has been proposed and tested in the numerical example to mitigate the effect of strategic behavior of generators in reactive power procurement by the system operator. The numerical examples are tested on the Nordic 32-bus system. © 2009 IEEE.published_or_final_versio

Adolescents with irritable bowel syndrome report increased eating-associated symptoms, changes in dietary composition, and altered eating behaviors: a pilot comparison study to healthy adolescents

About half of adult Irritable Bowel Syndrome (IBS) patients report symptoms with eating and disordered eating habits. However little is known about eating in adolescent IBS patients, a common age at which eating disorders develop. The aim of the study was to investigate if adolescents with IBS are more likely than healthy controls to experience eating associated symptoms, report disordered eating patterns, and show differences in diet composition

Exploring Astronautical Dentistry: A Review

The Human body reacts differently in different environment(s). With development in the field of astronomy, long distance trip to another planet is now possible. These trips require humans to stay in zero gravity conditions for a long time. Simulated microgravity is the best way to assess the physiologic changes in near zero gravity conditions, as it is not always possible to conduct scientific experiments in space. The purpose of this review is to determine the effects of zero gravity on oral cavity
