Exploration of the Conformational Dynamics of Major Histocompatibility Complex Molecules

open access: yesFrontiers in Immunology, 2017
Major histocompatibility complex (MHC) molecules are loaded with a wide variety of self- and non-self-peptides in their binding grooves and present these to T cell receptors (TCRs) in order to activate the adaptive immune system.

$\alpha$-Differentiable functions in complex plane

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020
In this paper, the conformable fractional derivative of order $\alpha$ is defined in complex plane. Regarding to multi-valued function $z^{1-\alpha}$, we obtain fractional Cauchy–Riemann equations which in case of $\alpha=1$ give classical Cauchy ...

On the Complexity of Classification Functions [PDF]

open access: yes38th International Symposium on Multiple Valued Logic (ismvl 2008), 2008
A classification function is a multiple-valued input function specified by a set of rules, where each rule is a conjunction of range functions. The function is useful for packet classification for internet, network intrusion detection system, etc. This paper considers the complexity of range functions and classification functions represented by sum-of ...

The analyticity of double complex variables functions

open access: yes上海师范大学学报. 自然科学版, 2023
Due to the complexity of complex functions, many textbooks focus on the nature of univariate variable complex functions, but just simply mention multi-complex variables functions.

Intermediate rings of complex-valued continuous functions

open access: yesApplied General Topology, 2021
For a completely regular Hausdorff topological space X, let C(X, C) be the ring of complex-valued continuous functions on X, let C ∗ (X, C) be its subring of bounded functions, and let Σ(X, C) denote the collection of all the rings that lie between C ...

On Complex Gamma-Function Integrals [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2020
It was observed recently that relations between matrix elements of certain operators in the ${\rm SL}(2,\mathbb R)$ spin chain models take the form of multidimensional integrals derived by R.A. Gustafson. The spin magnets with ${\rm SL}(2,\mathbb C)$ symmetry group and ${\rm L}_2(\mathbb C)$ as a local Hilbert space give rise to a new type of $Γ ...

Complex Networks of Functions

open access: yesCoRR, 2021
Functions correspond to one of the key concepts in mathematics and science, allowing the representation and modeling of several types of signals and systems. The present work develops an approach for characterizing the coverage and interrelationship between discrete signals that can be fitted by a set of reference functions, allowing the definition of ...

Topologies of Complex Networks: Functions and Structures [PDF]

open access: yes, 2007
During the last decade, significant efforts have been made toward improving our understanding of the topological structures underlying complex networks and illuminating some of the intriguing large-scale properties exhibited by these systems.

On the Complexity of Real Functions [PDF]

open access: yes46th Annual IEEE Symposium on Foundations of Computer Science (FOCS'05), 2005
We develop a notion of computability and complexity of functions over the reals, which seems to be very natural when one tries to determine just how "difficult" a certain function is. This notion can be viewed as an extension of both BSS computability [Blum, Cucker, Shub, Smale 1998], and bit computability in the tradition of computable analysis ...
