Most US consumers are charged a near-constant retail price for electricity, despite substantial hourly variation in the wholesale market price. This paper evaluates the rst program to expose residential consumers to hourly real-time pricing (RTP). I nd that enrolled households are statistically signi cantly price elastic and that consumers responded by conserving energy during peak hours, but...
Modeling disease with human pluripotent stem cells (hPSCs) is hindered because the impact on cell phenotype from genetic variability between individuals can be greater than from the pathogenic mutation. While "footprint-free" Cas9/CRISPR editing solves this issue, existing approaches are inefficient or lengthy. In this study, a simplified PiggyBac strategy shortened hPSC editing by 2 weeks and ...
In this paper we investigate the introduction of an export tax on steam coal levied by an individual country (Australia), or a group of major exporting countries. The policy motivation would be twofold: generating tax revenues against the background of improved terms-of-trade, while CO2 emissions are reduced. We construct and numerically apply a two-level game consisting of an optimal policy pr...
We use a unique dataset that combines the responses from an original survey of households, information about the structural characteristics of their homes, utility-provided longitudinal electricity usage records, plus utility program participation information, to study the uptake of energy efficiency incentives and their effect on residential electricity consumption. Attention is restricted to ...

BACKGROUND Bilateral renal agenesis/hypoplasia/dysplasia (BRAHD) is a relatively common, lethal malformation in humans. Established clinical risk factors include maternal insulin dependent diabetes mellitus and male sex of the fetus. In the majority of cases, no specific etiology can be established, although teratogenic, syndromal and single gene causes can be assigned to some cases. METHODOL...
Local Structure and Protons in Non-Stoichiometric Pseudo-Cubic Pollucite Mineral by Multinuclear NMR
The pollucite structure is considered as a candidate ceramic crystalline matrix for the immobilization and long-term storage of 135Cs 137Cs fission products, thus, their structural characteristics have particular importance. However, its local has not been fully resolved from reciprocal-space techniques infrared spectroscopy, important discrepancies exist in available literature. Two birefringe...
about 60 percent of the world's known reserves of oil reside in the middle east region. as such, any developments of this region are of utmost importance for the world economy. the strait of hormuz is the export conduit for 90 percent of the oil of the countries bordering the persian gulf, supplying 40 percent of world oil consumption, and is controlled by our country. since assessment of ...
Van der Woude syndrome (VWS) is a common form of syndromic cleft lip and palate and accounts for approximately 2% of all cleft lip and palate cases. Distinguishing characteristics include cleft lip with or without cleft palate, isolated cleft palate, bilateral lip pits, hypodontia, normal intelligence, and an autosomal-dominant mode of transmission with a high degree of penetrance. Previously, ...
Using natural gas is known as a clean energy resource and apart from environmental aspect, it is economically and politically of great importance so that countries having conventional and unconventional gas resources have increased investment in novel tech developments especially in unconventional ones. The aim of this study is to analyze the effect of shale gas production on the gas price in t...
