Exponential Size Distribution of von Willebrand Factor [PDF]

open access: yesBiophysical Journal, 2013
Von Willebrand Factor (VWF) is a multimeric protein crucial for hemostasis. Under shear flow, it acts as a mechanosensor responding with a size-dependent globule-stretch transition to increasing shear rates. Here, we quantify for the first time, to our knowledge, the size distribution of recombinant VWF and VWF-eGFP using a multilateral approach that ...

The practical electromagnetic effect in surface-enhanced Raman scattering observed by the lithographically fabricated gold nanosquare dimers

open access: yesAIP Advances, 2020
We experimentally investigated the practical electromagnetic effects in surface-enhanced Raman scattering (SERS), using the precisely fabricated array of gold nanosquare dimers. The array of gold nanosquare dimers was fabricated by electron-beam exposure

Darboux and Analytic First Integrals of the Generalized Michelson System [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics
The purpose of this work is to demonstrate that, for any value of a_1, a_2, and a_3, the generalized Michelson system u ̇= v,v ̇=w,w ̇= a_1 +a_2 v+ a_3 w-u^2/2 has neither a Darboux nor a rational first integral.

A Unifying Framework for Perturbative Exponential Factorizations [PDF]

open access: yesMathematics, 2021
We propose a framework where Fer and Wilcox expansions for the solution of differential equations are derived from two particular choices for the initial transformation that seeds the product expansion. In this scheme, intermediate expansions can also be envisaged. Recurrence formulas are developed.

Thermal Degradation of Vegetable Oils

open access: yesFoods, 2023
Vegetable oils provide lipids and nutrition and provide foods with a desirable flavor, color, and crispy texture when used to prepare fried foods. However, the oil quality is degraded at elevated temperatures, and thus must be examined frequently because

On exponential factorizations of matrices over Banach algebras [PDF]

open access: yesJournal of Algebra, 2022
We study exponential factorization of invertible matrices over unital complex Banach algebras. In particular, we prove that every invertible matrix with entries in the algebra of holomorphic functions on a closed bordered Riemann surface can be written as a product of two exponents of matrices over this algebra.

A simulation based optimization of factor-type exponential estimators in sample surveys with coefficients of variation and kurtosis

open access: yesFranklin Open, 2023
In the context of sample surveys, this article presents factor-type exponential ratio estimators as a technique for estimating population means. These estimators use supplementary information for an auxiliary variable, such as coefficients of variation ...

A new analytical control strategy for a magnetic suspension system under initial position dispersions [PDF]

open access: yesFME Transactions, 2021
A nonlinear magnetic suspension system is considered in this paper. A novel online algorithm based on analytical approach is presented to stabilize the suspended mass. The new algorithm employs a single analytical function to create the ball position and

Shor's Factoring Algorithm and Modular Exponentiation Operators

open access: yesQuanta, 2023
We provide a pedagogical presentation of Shor's factoring algorithm, which is a quantum algorithm for factoring very large numbers (of order of hundreds to thousands of bits) in polynomial time. In contrast, all known classical algorithms for the factoring problem take an exponential time to factor such large numbers.
