Quantile regression is a method to estimate the quantiles of the conditional distribution of a response variable, and as such it permits a much more accurate portrayal of the relationship between the response variable and observed covariates than methods such as least-squares or least absolute deviations regression. It can be expressed as a linear program, and, with appropriate preprocessing, i...

Waste reduction is a primary environmental protection policy in North Carolina. This manual is directed at small or medium-sized businesses such as yours and provides guidance for developing or expanding Waste reduction is defined and described briefly in the first chapter of the manual, and the benefits of waste reduction are highlighted. Two primary benefits of pursuing waste reduction are en...

This review essay debates the policy issues raised by the book Retooling for Growth: Building a 21 Century Economy in America’s Older Industrial Areas, edited by Richard M. McGahey and Jennifer S. Vey (Brookings Institution Press, 2008). I argue that the main rationale for adopting policies to revitalize older industrial cities is to improve the per capita earnings of urban residents. Therefore...

The paper provides novel approaches for a posteriori estimation of goal-oriented engineering analysis error caused by removing finite-sized negative features from a complex model, in the case of analysis of nonlinear elliptic physical phenomena. The features may lie within the model’s interior or along its boundary, and may be constrained with either Neumann or Dirichlet boundary conditions. Th...

Amitriptyline hydrochloride is a highly permeable active pharmaceutical ingredient (API). The function of these drugs is to block the reuptake of the neurotransmitters, norepinephrine and serotonin in the central nervous system. The nano-sized Amitriptyline (AT) imprinted polymer particles were synthesized successfully. The nanoparticles were characterized by Fourier transform infrared spectros...

The study explores adolescents' attitudes toward seeking help for emotional problems. The personal service gap is examined by asking adolescents about their willingness to refer themselves and others to formal (psychologists) and informal (friends) help sources, using a within-subjects design. The study included 662 Israeli adolescents in the 10th and 12th grades. The results indicate that adol...

Emotional problems figure prominently in many clinical conditions. Recent efforts to explain and treat these conditions have emphasized the role of emotion dysregulation. However, emotional problems are not always the result of emotion dysregulation, and even when emotional problems do arise from emotion dysregulation, it is necessary to specify precisely what type of emotion dysregulation migh...

We present an executable formally verified SAT encoding of ground classical AI planning problems. use the theorem prover Isabelle/HOL to perform verification. experimentally test and show that it can be used for reasonably sized standard benchmarks. also as a reference state-of-the-art SAT-based planner, showing sometimes falsely claims problems have no solutions certain lengths.
