Quark (dairy product) considered to be different types of fresh cheese, while in Eastern Europe cottage cheese is usually viewed as a type of quark (e.g. Russian for cottage cheese is "зернёный творог" "zernyony tvorog", literally "grainy quark"). Quark is similar to French fromage blanc, Indian paneer, and the queso fresco/queijo fresco made in the Iberian Peninsula and in some Latin American countries. It is distinct from Italian ricotta because ricotta (Italian "recooked") is made from scalded whey. Quark is somewhat similar to yogurt cheeses such as the South Asian "chak(k)a", the Arabic labneh, and the Central Asian suzma or kashk, but while
Top quark doublet, the mass value will be reduced by Higgs mixing angle effects in an unpredicted way. In the minimal supersymmetric extension of the Standard Model (MSSM), there are two Higgs doublets and the renormalization group equation for the top quark Yukawa coupling is slightly modified: where "y" is the bottom quark Yukawa coupling. This leads to a fixed point where the top mass is smaller, 170–200 GeV. The uncertainty in this prediction arises because the bottom quark Yukawa coupling can be amplified in the MSSM. Some theorists believe this is supporting evidence for the MSSM. The quasi-infrared fixed point has
