Let G = (V,E) be a graph of order n. A distance magic labeling of G is a bijection l : V → {1, . . . , n} for which there exists a positive integer k such that ∑ x∈N(v) l(x) = k for all v ∈ V , where N(v) is the neighborhood of v. We introduce a natural subclass of distance magic graphs. For this class we show that it is closed for the direct product with regular graphs and closed as a second f...

— Memristors are passive components with a varying resistance which depends on the previous voltage applied across the device. While memristors are naturally used as memory, memristors can also be used for other applications, including logic circuits. In this paper, a memristor only logic family, MAGIC (Memristor Aided LoGIC), is presented. In each MAGIC logic gate, memristors serve as an input...

MAGIC comprises two 17m diameter IACTs to be operated in stereo mode. Currently we are commissioning the second telescope, MAGIC II. The camera of the second telescope has been equipped with 1039 pixels of 0.1-degree diameter. Always seven pixels are grouped in a hexagonal configuration to form a cluster. This modular design allows easier control and maintenance of the camera. The pixel sensors...

From children’s parties to acts in Las Vegas, magic is one of the world’s most timeless forms of entertainment. Current psychological research on magic has started to focus on how magicians are best able to elicit the observer reactions associated with their craft, such as what methods are most successful, as well as what cognitive mechanisms are specifically driving the observers’ reactions. H...

A knight‟s tour on a board is a sequence of knight moves that visits each square exactly once. A knight‟s tour on a square board is called magic knight‟s tour if the sum of the numbers in each row and column is the same (magic constant). Knight‟s tour in higher dimensions (n > 3) is a new topic in the age-old world of knight‟s tours. In this paper, it has been proved that there can‟t be magic k...

MAGIC, 17 meters of diameter, is the world’s largest single dish Imaging Atmospheric Cherenkov Telescope, and reaches in the analysis the lowest energy threshold (60 GeV) among the VHE gamma detectors. Completed in September 2004, MAGIC started full operation with its first cycle of data taking in February 2005. MAGIC observations in the galaxy cover, among others, supernova remnants, the Galac...

Magic tricks violate the expected causal relationships that form an implicit belief system about what is possible in the world around us. Observing a magic effect seemingly invalidates our implicit assumptions about what action causes which outcome. We aimed at identifying the neural correlates of such expectation violations by contrasting 24 video clips of magic tricks with 24 control clips in...

The past few years have seen a resurgence of interest in the scientific study of magic. Despite being only a few years old, this “new wave” has already resulted in a host of interesting studies, often using methods that are both powerful and original. These developments have largely borne out our earlier hopes (Kuhn et al., 2008) that new opportunities were available for scientific studies base...
