Intra-Cultural Semiotics of a Combined Bird-with-Female-Head Motif in Metal Rings of the Semiosphere of the Seljuks of Iran [PDF]
زن در فرهنگ و هنر, 2022 Human-bird hybrid motifs have broad and sometimes conflicting meanings in many parts of the world. In the Islamic era, despite the prohibition of human and animal motifs, this motif is still used in works such as rings of the Seljuk period with a female ...

Diamond cable bracing with rings for steel Structures [PDF]
Numerical Methods in Civil Engineering, 2023 Cable bracing has many advantages, such as high tensile strength and lack of buckling in evaluation with traditional braces, the use of a cable as a brace is necessary.

A GRAPH WHICH RECOGNIZES IDEMPOTENTS OF A COMMUTATIVE RING [PDF]
Journal of Algebraic Systems, 2020 In this paper we introduce and study a graph on the set of ideals of a commutative ring $R$. The vertices of this graph are non-trivial ideals of $R$ and two distinct ideals $I$ and $J$ are adjacent if and only $IJ=Icap J$.

Classification of Zero Divisor Graphs of Commutative Rings of Degrees 11,12 and 13 [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2014 In 2005 Wang investigated the zero divisor graphs of degrees 5,6,9 and 10. In 2012 Shuker and Mohammad investigated the zero divisor graphs of degrees 7 and 8. In this paper, we consider zero divisor graphs of commutative rings of degrees 11, 12 and 13.

First M87 Event Horizon Telescope Results. V. Physical Origin of the Asymmetric Ring [PDF]
Astrophysical Journal, 2019 The Event Horizon Telescope (EHT) has mapped the central compact radio source of the elliptical galaxy M87 at 1.3 mm with unprecedented angular resolution. Here we consider the physical implications of the asymmetric ring seen in the 2017 EHT data.

Co-EP-Ness and EP-Ness Involving the Inverse along an Element
Mathematics, 2023 Let a,d be two elements in rings and a∥d be the inverse of a along d. When a∥d exists, we obtain several characterizations for the invertibility of aa∥d−a∥da, which is related to the invertibility of elements expressed by certain functions of a,d and ...

Universal interferometric signatures of a black hole’s photon ring [PDF]
Science Advances, 2019 A black hole image contains a series of increasingly narrow rings measurable with progressively longer interferometers. The Event Horizon Telescope image of the supermassive black hole in the galaxy M87 is dominated by a bright, unresolved ring.
