This paper examines the role of some key economies in economic contagion across global value chains using input-output analysis and complex network statistics. The empirical research focuses on China, France, Germany, Italy, Japan, Korea, United Kingdom, States. A range novel measures were used to measure nature extent chain relationships. results reveal that, because high interdependence inter...

investigating a hadith narrated from the fifth shi‘a imam (abu ja‘far muhammad al-baqir) in two quranic commentaries of al-tibyan and majma‘al-bayan, the present essay finds its origin in al-masabih fi tafsir al-qur’an by abu al-qasim wazir maghribi (370-418 a.h.). wazir maghribi attributes that hadith to abu ja‘far in an ambiguous way. however, that hadith is neither narrated in shiite books o...

High-resolution transmission electron microscopy revealed nearly atomically precise images of stepping conformational change and translational motion of single hydrocarbon molecules confined in carbon nanotubes. One or two C12 or C22 alkyl chains were tethered to a carborane end group and then embedded in the nanotubes. Images of the hydrocarbon chains interacting with each other and with a gra...

Let $G$ be a molecular graph with vertex set $V(G)$, $d_G(u, v)$ the topological distance between vertices $u$ and $v$ in $G$. The Hosoya polynomial $H(G, x)$ of $G$ is a polynomial $sumlimits_{{u, v}subseteq V(G)}x^{d_G(u, v)}$ in variable $x$. In this paper, we obtain an explicit analytical expression for the expected value of the Hosoya polynomial of a random benzenoid chain with $n$ hexagon...

In this paper we enumerate fuzzy subgroups, up to a natural equivalence, of some finite abelian p-groups of rank two where p is any prime number. After obtaining the number of maximal chains of subgroups, we count fuzzy subgroups using inductive arguments. The number of such fuzzy subgroups forms a polynomial in p with pleasing combinatorial coefficients. By exploiting the order, we label the s...

The primary purpose of this paper is to highlight for the research community and practitioners the various aspects of using VMI-type supply chains in today’s business environment as well as a number of directions for future studies. In this regard, fifty articles published in major international journals, beginning in 1995, which contribute to the VMI-type supply chains are reviewed via a syste...

there is no doubt that the way to gain access to religious rulings and doctrines is the sunna of the prophet and the imams, as only second to the holy qur’ān, which is reported in thousands of traditions in various tradition books. in the meantime, every theologian and ḥadīth researcher has to leave behind two stages for a proper understanding of traditions: in the first stage, he is to conside...

The asymmetric price volatility transmission issue in agricultural supply chains has been ignored the previous literature. This paper applies an asymmetrical MGARCH-BEKK model to investigate with application Chinese pork market. Additionally, we use Zivot–Andrews unit root test a structural break examine whether piglet, hog, and prices have breaks. results show that pork’s market breakpoint 200...
