FUJIFILM’s newly-developed ‘AMULET’, a digital mammography system, simultaneously realizes high-image quality, low-dose image acquisition and high-throughput as well as patient-oriented design. A detector mounted on AMULET directly converts X-ray signals into electronic signals to readout the electronic signals by using a uniquely developed “Direct Optical Switching” readout method in its imagi...

We propose a method for the direct inversion of the permeability field of a porous medium from the analysis of the displacement of a passive tracer. By monitoring the displacement front at successive time intervals (for example, using a tomographic method), the permeability can be directly obtained from the solution of a nonlinear boundary-value problem. Well posedness requires knowledge of the...

In this paper, using the direct method we study the generalized Hyers-Ulam-Rassias stability of the following quadratic functional equations (2 ) ( ) 6 ( )     f x y f x y f x and (3 ) ( ) 16 ( )     f x y f x y f x for the mapping f from normed linear space in to 2-Banach spaces.

various psychotherapies for post-traumatic stress disorder and disturbances associated with it are used. the purpose of this review was to introduce of traditional and modern psychotherapy in the treatment of post-traumatic stress disorder. the data was collected by searching of online databases, english articles selected from science direct, pubmed, proquest, and persian articles from medlib, ...

this research study employed a mixed-methods approach to investigate the test takers’ perceptions and anx- iety in relation to an english language proficiency test called community english program (cep). this study also evaluated the direct and semi-direct modes for speaking module of this test. to this end, 300 eng- lish as foreign language (efl) students were recruited in the study as test ta...

The Gillespie τ-Leaping Method is an approximate algorithm that is faster than the exact Direct Method (DM) due to the progression of the simulation with larger time steps. However, the procedure to compute the time leap τ is quite expensive. In this paper, we explore the acceleration of the τ-Leaping Method using Graphics Processing Unit (GPUs) for ultra-large networks (>0.5e(6) reaction chann...

Land is a kind of basic resources and of great importance to the survival and development of human beings. Due to the conflict between the limited amount of land and the unlimited development of human beings, land surely plays a significant role in national security and social development. The academic circle has introduced the social stability price to the pricing system of farmland, which ref...

In this contribution we study the statistical properties of a number of closed-loop identiication methods and parameterizations. A focus will be on asymptotic variance expressions for these methods and by studying the asymptotic variance for the parameter vector estimates we show that indirect methods fail to give better accuracy than the direct method.

This article briefly explores the twelve principles of language teaching and learning formulated by H. Douglas Brown and also the underlying principles of some of the earlier grammar-based methods to calculate how consistent these principles are with those of Brown’s. The grammarbased approaches chosen for evaluation are the Grammar Translation Method, the Direct Method, the Audiolingual Method...
