Best System of Creation according to Transcendent Philosophy [PDF]

open access: yesحکمت صدرایی, 2019
Best system of creation means the best and most perfect system that God created. The question is that whether this actual creation system is the most perfect possible world or not.

Coloring of graph of ring with respect to idempotents [PDF]

open access: yesMathematica Bohemica
Let $R$ be a ring with nonzero identity. A graph $G_{{\rm Id}}(R)$ of $R$ with respect to idempotents of $R$ has elements of $R$ as vertices and distinct vertices $x$, $y$ are adjacent if and only if $x + y$ is an idempotent of $R$.

A robust parameter estimation approach based on stochastic fractal search optimization algorithm applied to solar PV parameters

open access: yesEnergy Reports, 2021
Modeling of solar photovoltaic (PV) cell/modules to estimate its parameters with the measured current–voltage (I–V ) values is a very important issue for the control, optimization, and effectiveness of the PV systems.

Voronoi-Delaunay analysis of normal modes in a simple model glass

open access: yes, 1999
We combine a conventional harmonic analysis of vibrations in a one-atomic model glass of soft spheres with a Voronoi-Delaunay geometrical analysis of the structure.

A Zariski-local notion of F-total acyclicity for complexes of sheaves [PDF]

open access: yes, 2016
We study a notion of total acyclicity for complexes of flat sheaves over a scheme. It is Zariski-local - i.e. it can be verified on any open affine covering of the scheme - and it agrees, in their setting, with the notion studied by Murfet and Salarian ...

Pfaffian Point Processes from Free Fermion Algebras: Perfectness and Conditional Measures

open access: yes, 2021
The analogy between determinantal point processes (DPPs) and free fermionic calculi is well-known. We point out that, from the perspective of free fermionic algebras, Pfaffian point processes (PfPPs) naturally emerge, and show that a positive contraction

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Note on quantum entanglement and quantum geometry

open access: yesPhysics Letters B, 2019
In this note we present preliminary study on the relation between the quantum entanglement of boundary states and the quantum geometry in the bulk in the framework of spin networks.

Perfect fluids [PDF]

open access: yesSciPost Physics, 2018
We present a systematic treatment of perfect fluids with translation and rotation symmetry, which is also applicable in the absence of any type of boost symmetry. It involves introducing a fluid variable, the kinetic mass density , which is needed to define the most general energy-momentum ...

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

open access: yesFEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status
