Green's function topology of Majorana wires

New Journal of Physics, 2013
We represent the $\mathbb {Z}_2$ topological invariant characterizing a one-dimensional topological superconductor using a Wess–Zumino–Witten dimensional extension. The invariant is formulated in terms of the single-particle Green's function which allows

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

FEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Signal from noise retrieval from one and two-point Green's function - comparison

, 2015
We compare two methods of eigen-inference from large sets of data, based on the analysis of one-point and two-point Green's functions, respectively. Our analysis points at the superiority of eigen-inference based on one-point Green's function. First, the

Protonophore activity of short‐chain fatty acids induces their intracellular accumulation and acidification

FEBS Letters, EarlyView.
The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Efficient Atomistic Simulation of Heterostructure Field-Effect Transistors

IEEE Journal of the Electron Devices Society, 2019
In this paper, atomistic-level quantum mechanical simulations are performed for nanoscale field-effect transistors (FETs) with lateral or vertical heterojunction, within the non-equilibrium Green's function formalism.

Green's function theory of spatiotemporally modulated loaded wire surface

Physical Review Research, 2023
In this paper we explore the two-dimensional Green's function problem above a spatiotemporally modulated loaded wire media. We suggest a spatiotemporal spectral representation to the space-time domain Green's function.

Modifications in FLAP's second cytosolic loop influence 5‐LOX interaction, inhibitor binding, and leukotriene formation

FEBS Letters, EarlyView.
The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

Pedagogical introduction to equilibrium Green's functions: condensed-matter examples with numerical implementations

Revista Brasileira de Ensino de Física
The Green's function method has applications in several fields in Physics, from classical differential equations to quantum many-body problems. In the quantum context, Green's functions are correlation functions, from which it is possible to extract ...

Green's Function Techniques for Infinite Nuclear Systems

Frontiers in Physics, 2020
I review the application of self-consistent Green's function methods to study the properties of infinite nuclear systems. Improvements over the last decade, including the consistent treatment of three-nucleon forces and the development of extrapolation ...
