A note on the joint measurability of POVMs and its implications for contextuality

The purpose of this note is to clarify the logical relationship between joint measurability and contextuality for quantum observables in view of recent developments [1-4].Comment: are welcome! This note may be revised further in due cours

Welcome Note

 Good information is the best medicine.” – Dr. Michael E. DeBakey With this quote in mind from a giant leader in medicine, I welcome all the readers to the inaugural edition of International JRMC. In today’s world of healthcare where there is an overload of information some good, some poor, and some false it is very encouraging that RMU has taken the bold step of launching JRMC International.<br> This is unique in nature for Pakistan as it is primarily focused on bridging the divide between good scientific research being done in Pakistan and that from outside of Pakistan. With contributions from local, national, and international researchers, doctors, and scientists, whether local projects or international this journal hopes to elevate the scholarly activity of learners in Pakistan.<br> Globalization of the world has brought new opportunities and new challenges. On the one hand, access to information and the opportunities to publish and collaborate have expanded. Still, on the other hand, clinicians have been forced to stay abreast with up-to-date information in their respective fields. Fast-changing paradigms of each sub-specialty of Medicine, the ever-increasing role of Artificial-Intelligence (AI), the importance of data mining, and complex misinformation (infodemic) call for a further refined approach to curriculum. Scholarly journals anchored and supported by esteemed and prestigious institutions like RMU play a vital role in this regard. Pakistan is lucky to have a glorious reputation for its medical colleges and physicians, many of whom are now at leading positions at international institutions. Bringing global experience to embed it in unique epidemiologic data and research outcomes of a country like Pakistan will go a long way in nurturing future scientists.<br> In this issue, you will hear about a variety of topics and varied authors from different parts of the world. I encourage you to submit your original research so that this journal becomes a reference for a bigger audience.&nbsp

Some elementary examples of quartics with finite-dimensional motive

This small note contains some easy examples of quartic hypersurfaces that have finite-dimensional motive. As an illustration, we verify a conjecture of Voevodsky (concerning smash-equivalence) for some of these special quartics.Comment: 5 pages, to appear in Annali dell'Universita di Ferrara, comments welcome ! arXiv admin note: substantial text overlap with arXiv:1611.0881
