In this paper we conduct a laboratory experiment to test the extent to which Moore and Repullo’s subgame perfect implementation mechanism induces truth-telling in practice, both in a setting with perfect information and in a setting where buyers and sellers face a small amount of uncertainty regarding the good’s value. We find that Moore-Repullo mechanisms fail to implement truth-telling in a s...

The purpose of this paper is to analyze the Moore-Penrose pseudo-inversion symmetric real matrices with application in graph theory. We introduce a novel concept positively and negatively pseudo-inverse graphs. also give sufficient conditions on elements block matrix yielding an explicit form its pseudo-inversion. Using we can construct graphs for class which are constructed from original by ad...

in this paper‎, ‎we study the extremal‎ ‎ranks and inertias of the hermitian matrix expression $$‎ ‎f(x,y)=c_{4}-b_{4}y-(b_{4}y)^{*}-a_{4}xa_{4}^{*},$$ where $c_{4}$ is‎ ‎hermitian‎, ‎$*$ denotes the conjugate transpose‎, ‎$x$ and $y$ satisfy‎ ‎the following consistent system of matrix equations $a_{3}y=c_{3}‎, ‎a_{1}x=c_{1},xb_{1}=d_{1},a_{2}xa_{2}^{*}=c_{2},x=x^{*}.$ as‎ ‎consequences‎, ‎we g...

This article presents the preliminary results of an Emergency Remote Teaching (ERT) experience (Hodges, Moore, Lockee, Trust & Bond, 2020) a foreign language professor during COVID-19 pandemic. Using qualitative methodology, technological and educational obstacles were found, such as participation in videoconferences, implementation real tasks, use humor motivation students. It is concluded...

We investigate the complex and Kähler attractor mechanisms of moduli spaces Calabi–Yau 3-folds. The mechanism was previously studied by Ferrara–Kallosh–Strominger, Moore others in string theory. It is concerned with minimizing problems normalized central charges middle homology classes defines a new interesting class 3-folds called, varieties. In light mirror symmetry, we introduce define varie...

An exploding demand for processing capabilities related to the emergence of Internet Things (IoT), Artificial Intelligence (AI), and big data, has led quest increasingly efficient ways expeditiously process rapidly increasing amount data. These include different approaches like improved devices capable going further in more Moore path but also new architectures beyond getting than Moore. Among ...
