Dealing with the trigonometric functions of two angles may be pretty tough, unless you know the relationship between them. So what happens if you know that α and β are supplementary angles? Then, as α + β =
The term x'iXj=cos 0ij estimates cos 0ij= μiμy. The asymptotic joint distribution of the terms will be studied when all the vectors μi μ are distinct, and for the special case when all the vectors μi=μ, so that all the terms are zero. These very different results have a ...

I'm trying to wrap my head around the concept. we use 3 rotations to transfer our regular cartesian coordinates (3 x,y,z unit vectors) to other 3 unit vectors. each rotation is associated with an angle. so far I'm good. but now I saw in Landau's and Lifshitz's "mechanics" book...
topological phases are further compounded in the class of 3D TCIs that have become known as higher-order TCIs (HOTIs), in which most—if not all—of the 2D surface states are gapped, and the 1D hinges (edges) between gapped surfaces bind gapless chiral or helical modes18,19,20,21,22....
Whilst COSMIC-2 do not provide L1 and L2 bending angles, here we use the derivative of slantwise TEC S, with respect to the impact parameter a, ∂S/∂a. Culverwell et al. (2023) showed that, to a good approximation, this is proportional to the difference between the L2 and L1 be...
The Corresponding Angles Theorem states that "If two angles are corresponding, they are equal." This is also known as the Corresponding Angles Postulate because a postulate is accepted as true and is used to prove other theorems. To prove the theorem, one other relationship between angles created...
Besides the representation method discussed above, protein backbone structures can also be represented by Cα atoms since successive Cα atoms have almost the same dis- tance. In this case, instead of φ , ψ , and ω , two other angles θ and τ are used. Note θ and τ are ...
However, secondary structure states are described as discrete classes and there is no clear boundary between coil and helical/strand states. It is a significant step towards establishing the structure and function of a protein to predict local conformation of the polypeptide chain. The local ...
The two vectors are merged to create the final input vector for the SVM classifiers. Lastly, the predictions are filtered to give the final result. Full size image Filtering Because the prediction is based on individual residues, the SVM outputs include some β-turns that are shorter than four...
