Unicode Nearly Plain-Text Encoding of Mathematics, Version 3 (Unicode Technical Note #28) is now posted. The differences between Version 1 and 2 of that paper are largely cosmetic, but there were enough changes in Version 2 to merit a new number. Version 2 is mostly implemented in Microsoft...
In this paper, we explore cosmological bouncing solutions to investigate the cosmic evolution in the framework of energy-momentum squared gravity. We consi
The aim of this paper is to propose a new family of codes. We define this family over the ring R=∑^4_{s=0}v^s_5A_4, with v^5_5=v_5. We derive its properti... M Malki,K Chatouh - 《Mathematical Modeling & Computing》 被引量: 0发表: 2023年 加载更多来源...

Grade 2 ratings predicted math ability at grade 3, more so than predictors from grade 3. These findings, although based on informal analyses not intended to substitute for validated assessments of disposition, support the notions that distinct aspects of dispositions towards math emerge in early ...
