Noticing that the " point-form " approach referred to in many recent works implies physics described on hyperplanes, an approach inspired from Dirac's one, which involves a hyperboloid surface, is presented. A few features pertinent to this new approach are emphasized. Consequences as for the calculation of form factors are discussed.

this study was designed to find which one of the three different presentations, i.e. input, input-output, and output-input, will be more effective in iranian efl learners' vocabulary acquisitions. to this end, first 54 out of 64 female students, aged from 19 to 23 years, with an average of 21, were selected out of starter-level efl learners at the university of tarbiat moalem in bandar abb...

Martin Powell suggests that the death of the English National Health Service (NHS) has been announced so many times we are at risk of not noticing should it actually happen. He is right. If we ‘cry wolf’ too many times, we risk losing sight of what is important about the NHS and why.

This article reports on two aspects of a professional learning (PL) and research study. Twenty-five teachers participated in two-year PL program that sought to support implement classroom connectivity technology (CCT) their Algebra I classrooms. Students one school who learned with CCT outperformed peers without CCT. Therefore, we explored the practices teacher whose students attained higher ac...

Abstract Although strong references to expertise in different theoretical approaches teacher noticing have been made the last decades, empirical knowledge about development of from novice expert level is scarce. The present study aims close this research gap by comparing three groups mathematics teachers with degrees professional teaching experience—pre-service at master’s level, early career t...

A multi-purpose dual Multiple-Input-Multiple-Output (MIMO) antenna system for 5G mobile systems is presented in this paper. The proposed consists of two sets MIMO antennas on a single board. 8-port antenna, placed the board, working over 3.5 GHz (3.4 GHz-3.6 GHz) band with dimensions 150 mm ×70 mm. 4-port system, chassis, operating 5.2 WLAN/5.5 WiMAX/5.8 GHz/6 WiFi 20 × 7 prototype designed and...

With the development of online education system, personalized recommendation has played an essential role. In this paper, we focus on developing path systems that aim to generating and recommending entire learning given user in each session. Noticing existing approaches fail consider correlations concepts path, propose a novel framework named Set-to-Sequence Ranking-based Concept-aware Learning...
