Q uantum interference effects lie at the heart of technologies that promise radically new capabilities for sensors, secure communications, and computing. Most existing experiments and applications rely on one photon interfering with itself, or two photons interfering with each other. However, the interference of a larger number of particles leads to a richer variety of phenomena, and may enable...
The arguments presented by González-Nuevo et al. (2006) in favour of theMexican Hat Wavelet Family (MHWF) are critically discussed here. These authors allege the optimal properties of this new class of filters in the detection of point sources embedded in a noise background but their claim is not based upon a solid mathematical foundation and proof.
Migrants from rural Mexico usually move abroad with the idea to return once they have improved their economic situation. Although they do not always go back, Mexican migrants often plan their return before leaving. In any case, the imagined return persists for a long time in their minds. This paper analyzes the ways in which rural migrants from southern Veracruz and western Mexico imagine a bet...
Cilt, tezhip ve ebrû gibi İslam sanatları, hat sanatının merkezî rolüyle gelişmiştir. Hat teşhiri başlangıçta Kur’an-ı Kerim’in istinsahı yapılar üzerindeki kitabelerle olmuştur. medeniyeti, farklı milletlerle coğrafyalarda temsil edilmiş ancak hepsinin ortak sanatı her zaman Orta Çağda net bir şekilde kaideleri kuralları olan tek sanatın olduğu bilinmektedir. tarihin hiçbir döneminde belirli z...
In this note, we give an explicit polynomial-time executable strategy for Peter Winkler’s hat guessing game that gives superior results if the distribution of hats is imbalanced. While Winkler’s strategy guarantees in any case that ⌊n/2⌋ of the n player guess their hat color correct, our strategy ensures that the players produce max{r, b} − 1.2n2/3 − 2 correct guesses for any distribution of r ...
A new hexaazatriphenylene (HAT) derivative formed by the fusion of three HAT units has been prepared and its electronic and molecular structures have been fully characterized by optical and vibrational Raman spectroscopy, electrochemistry, solid-state UV and inverse photoemission spectroscopy (UPS and IPES), and by quantum-chemical calculations. A comparative HAT versus tri-HAT study was perfor...
