We obtain criteria for entanglement and the EPR paradox for spin-entangled particles and analyse the effects of decoherence caused by absorption and state purity errors. For a two qubit photonic state, entanglement can occur for all transmission efficiencies. In this case, the state preparation purity must be above a threshold value. However, Bohm's spin EPR paradox can be achieved only above a...

In quantum theory, no-go theorems are important as they rule out the existence of a particular physical model under consideration. For instance, the Greenberger-Horne-Zeilinger (GHZ) theorem serves as a no-go theorem for the nonexistence of local hidden variable models by presenting a full contradiction for the multipartite GHZ states. However, the elegant GHZ argument for Bell's nonlocality do...

I propose to give a solution to the sorites paradox with respect to monadic predicates expressing sensible qualities that is squarely within the epistemicist camp of Williamson (1994, 1996), Sorenson (1988, 2001), and Rescher (2009). In particular, I will address what appears to be the Achilles’ heel of that account: namely, the problem of giving a plausible story about how an exact boundary ar...

There is considerable disagreement over whether or not gaining viability bene¢ts to o¡spring could be substantial enough to overcome the costs of female choosiness. A recent review suggested that the `lek paradox' might be resolved by large indirect bene¢ts as indicated by highly heritable ornamental traits. We selected males of a wolf spider Hygrolycosa rubrofasciata in relation to their sexua...

The Surprise Exam Paradox continues to perplex and torment despite the many solutions that have been offered. This paper proposes to end the intrigue once and for all by refuting one of the central pillars of the Surprise Exam Paradox, the “No Friday Argument,” which concludes that an exam given on the last day of the testing period cannot be a surprise. This refutation consists of three argume...

The enormous amounts of data that are generated in the healthcare process and stored in electronic health record (EHR) systems are an underutilized resource that, with the use of data science applications, can be exploited to improve healthcare. To foster the development and use of data science applications in healthcare, there is a fundamental need for access to EHR data, which is typically no...

The economic history of Argentina presents one of the most dramatic examples of divergence in the modern era. What happened and why? This paper reviews the wide range of competing explanations in the literature and argues that, setting aside deeper social and political determinants, the various economic mechanisms in play defy the idea of a monocausal explanation.

In recent years there has been a revitalised interest in nonclassical solutions to the semantic paradoxes. In this paper I show that a number of logics are susceptible to a strengthened version of Curry’s paradox. This can be adapted to provide a proof theoretic analysis of the ω-inconsistency in Lukasiewicz’s continuum valued logic, allowing us to better evaluate which logics are suitable for ...

Many canonical geometric structures have been found to be closely related to stability in the sense of geometric invariant theory. For the existence of Kähler-Einstein metrics, this is the classical conjecture of Yau [14, 15, 16]. The necessity of several notions of stability has been established in this case by Tian [12] and by Donaldson [3]. In the variational approach, the existence of Kähle...

This paper compares the legislative difference of physical responsibility and economic responsibility in the developed countries and districts. Learning from the comparison analysis of the cognizance, we can find a proper way for China to determine the one who should undertake physical responsibility and economic responsibility, and the method of performance. In this way, we can make full use o...
