TESTING THE GRAVITY P-MEDIAN MODEL EMPIRICALLY

Testing the gravity p-median model empirically

Regarding the location of a facility, the presumption in the widely used p-median model is that the customer opts for the shortest route to the nearest facility.However, this assumption is problematic on free markets since the tandylsathers.shop customer is presumed to gravitate to a facility by the distance to and the attractiveness of it.The rece

Dark matter for excess of AMS-02 positrons and antiprotons

We propose a dark matter explanation to simultaneously account for the excess 7-OH of antiproton-to-proton and positron power spectra observed in the AMS-02 experiment while having the right dark matter relic abundance and satisfying the current direct search bounds.We extend the Higgs triplet model with a hidden gauge symmetry of SU(2)X that is br
