Heavy quarkonium decays and transitions are discussed in the framework of nonrelativistic effective field theories. Emphasis is put on the matching procedure in the nonperturbative regime. Some exact results valid for the magnetic dipole couplings are discussed. INTRODUCTION In the last years the B factories, CLEO and BES have produced a large amount of new data for heavy quarkonium observables...

Attempts to apply effective field theory (EFT) methods to nonrelativistic nucleon-nucleon (N N) scattering have raised questions about the nature and limitations of an EFT expansion when used nonperturbatively. We discuss the characteristics of a meaningful EFT analysis and compare them with traditional approaches to N N scattering. A key feature of an EFT treatment is a systematic expansion in...

BACKGROUND The purpose of this investigation is to determine the efficacy of emotionally focused couples therapy (EFT-C) on enhancement of marital adjustment in infertile couples. MATERIALS AND METHODS This was a semi-experimental study with a pre- and post-test design. We selected 30 infertile couples (60 subjects) by purposive sampling. Couples were randomly assigned to two groups, sample a...

background: cardiac dysfunction due to chronic anemia and hemosiderosis are the major causes of death among patients with thalassemia intermedia. this study was performed to compare the cardiac function in thalassemia intermedia patients with normal subjects by means of echocardiography. materials and methods: this was a case-control study performed on 22 patients affected by thalassemia interm...

OBJECTIVE To determine the relationship between central adiposity parameters and autonomic nervous system (ANS) dysfunction. SUBJECTS AND METHODS The study included 114 obese individuals without any cardiovascular risk factors. Weight (in kg), height (in m), and waist circumference (WC; in cm) were measured and body mass index was calculated. Echocardiographic examination was performed to mea...

Emotional Freedom Techniques (EFT) has moved in the past two decades from a fringe therapy to widespread professional acceptance. This paper defines Clinical EFT, the method validated in many research studies, and shows it to be an “evidence-based” practice. It describes standards by which therapies may be evaluated, such as those of the American Psychological Association (APA) Division 12 Task...

OBJECTIVE The objective of this pilot study was to compare the efficacy of Emotional Freedom Techniques (EFT) with that of Cognitive-Behavioral Therapy (CBT) in reducing adolescent anxiety. DESIGN Randomized controlled study. SETTINGS This study took place in 10 schools (8 public/2 private; 4 high schools/6 middle schools) in 2 northeastern states in the United States. PARTICIPANTS Sixty-...

This paper describes the development and experimental implementation of a realtime earthquake simulation test method for large-scale structures. The method, e¬ective force testing (EFT), is based on a transformation of coordinates, in which case the structure is ­ xed at the base (similar to the set-up for the pseudo-dynamic (PsD) test method); however, in the case of EFT, the method is based o...
