crust breaking of saffron is an important operation at the first stage of growth that should be accuratly operated as in this period sprouts of saffron rise up to near the soil surface. after primary irrigation, farmers soften the soil surface by means of different cultivation implements, which enables saffron flowers arise from subsurfarce. this research was conducted to compare tillage implem...

In this paper, the connection between Menger probabilistic norms and H"{o}hle probabilistic norms is discussed. In addition, the correspondence between probabilistic norms and Wu-Fang fuzzy (semi-) norms is established. It is shown that a probabilistic norm (with triangular norm $min$) can generate a Wu-Fang fuzzy semi-norm and conversely, a Wu-Fang fuzzy norm can generate a probabilistic norm.

It is often assumed that primordial perturbations are statistically isotropic, which implies, among other properties, that their power spectrum is invariant under rotations. In this article, we test this assumption by placing bounds on deviations from rotational invariance of the primordial spectrum. Using five-year Wilkinson Microwave Anisotropy Probe cosmic microwave anisotropy maps, we set l...

We present several polynomialand quasipolynomial-time approximation schemes for a large class of generalized operator norms. Special cases include the 2 → q norm of matrices for q > 2, the support function of the set of separable quantum states, finding the least noisy output of entanglement-breaking quantum channels, and approximating the injective tensor norm for a map between two Banach spac...

Behavior in social groups follows unwritten codes, with the social group one is embedded in defining what behavior is acceptable and what is not. Prior research has found strong tendencies toward informational isomorphism in groups in online social networks, as social peers seem to establish a shared understanding of what behavior is acceptable and what informational content is okay to share. H...

Cancer chemotherapy: its effect and impact Most cancer patients, especially those with advanced disease, receive treatment with a cocktail of cytotoxic drugs, many of which are associated with severe side effects, both in the short and longer term. These lead to dose reductions and delays in treatment and can even mean that treatment has to be stopped early, limiting the use of otherwise very e...
