Stochastic Gross-Pitaevsky Equation for BEC via Coarse-Grained Effective Action

, 2007
We sketch the major steps in a functional integral derivation of a new set of Stochastic Gross-Pitaevsky equations (GPE) for a Bose-Einstein condensate (BEC) confined to a trap at zero temperature with the averaged effects of non-condensate modes ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Existence of solutions of an integral equation of Chandrasekhar type in the theory of radiative transfer

Electronic Journal of Differential Equations, 2006
We give an existence theorem for some functional-integral equations which includes many key integral and functional equations that arise in nonlinear analysis and its applications.

QQ-system and non-linear integral equations for scattering amplitudes at strong coupling

Journal of High Energy Physics, 2020
We provide the two fundamental sets of functional relations which describe the strong coupling limit in AdS 3 of scattering amplitudes in N $$ \mathcal{N} $$ = 4 SYM dual to Wilson loops (possibly extended by a non-zero twist l): the basic QQ-system and ...

Common Fixed Point Theorems for Contractive Mappings of Integral Type in G-Metric Spaces and Applications

Journal of Function Spaces, 2021
Two common fixed point theorems for weakly compatible mappings satisfying contractive conditions of integral type in G-metric spaces are demonstrated. The results obtained in this paper generalize and differ from a few results in the literature and are ...

Functional Integral Approach in the Theory of Color Superconductivity [PDF]

, 2001
In this series of lectures we present the functional integral method for studying the superconducting pairing of quarks with the formation of the diquarks as well as the quark-antiquark pairing in dense QCD.
