Color co-occurrence method (CCM) texture statistics were used as input variables for a backpropagation (BP) neural network weed classification model. Thirty-three unique CCM texture statistic inputs were generated for 40 images per class, within a six class data set. The following six classes were studied: giant foxtail, large crabgrass, common lambsquarter, velvetleaf, ivyleaf morningglory, an...

We apply results from linear programming to show that the relaxation of model checking over integers to reals is accurate i e yields a full test of temporal properties for a large class of concurrent systems We de ne abstractions similar to widening and narrowing that accelerate least and greatest xpoint computations in model checking over integers or reals We show that these abstractions are a...

We hypothesize that the tendency to frame narrowly is related to an individual’s time preference. To test this, we confront a large sample of the Dutch population with a series of incentivized investment decisions and elicit time preferences. We find that the tendency to frame narrowly is not generally related to discount rates. At the same time, we find that it is easier to induce impatient in...

abstract We review how external magnetic fields act as perfect probes of the non-abelian nature of the electroweak theory.

Background: Narrow band Ultraviolet B (NBUVB) has been used successfully for the treatment of vitiligo. Recently, topical calcipotriol has also been used as immunotherapy or as a part of combination therapies. The aim of this study was to compare the clinical efficacy and safety of NBUVB and NBUVB plus topical calcipotriol in the treatment of generalized vitiligo.Methods: NBUVB phototherapy was...

Anomalous transport of heat and particles is known to be a key issue for fusion devices. In the present paper the anomalous transport of fast ions is investigated. High transit frequencies of the fast ions lead to the assumption that there is only very weak interaction with the low-frequency turbulence. However, our results indicate a significant fast ion particle transport due to the turbulenc...
