On the negative coupling O(N) model in 2d at high temperature

open access: yesJournal of High Energy Physics
In this work, I consider N-component scalar quantum field theory in two dimensions interacting with an upside-down quartic potential. Working in the large N limit, the model can be solved non-perturbatively using the saddle-point method for sufficiently ...

Prediction of Stress Increase at Ultimate in Unbonded Tendons Using Sparse Principal Component Analysis

open access: yesInternational Journal of Concrete Structures and Materials, 2019
While internal and external unbonded tendons are widely utilized in concrete structures, an analytical solution for the increase in unbonded tendon stress at ultimate strength, $$\Delta f_{ps}$$ Δfps , is challenging due to the lack of bond between ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

open access: yesFEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Regresion PLS y PCA como Solucion al Problema de Multicolinealidad en Regresion Multiple

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2011
We present and compare principal components regression and partial least squares regression, and their solution to the problem of multicollinearity. We illustrate the use of both techniques, and demonstrate the superiority of partial least squares.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Compensation and Auditing with Correlated Information [PDF]

open access: yes
An extensive academic literature exists on the optimal compensation of top executives. A less-developed literature pertains to the optimal compensation of middle management personnel. The goal of this paper is to address that concern. The setup we use is

A common solution to a pair of linear matrix equations over a principal ideal domain

open access: yes, 1991
A necessary and sufficient condition for the existence of a common solution to a pair of linear matrix equations over a principal ideal domain is obtained. The equations are of the type Ai = BiXCi for i = 1,2.

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

open access: yesFEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

On the Determination and Use of Principal Lines

open access: yesEngineering Transactions, 1977
Assuming plane strain for Huber-Mises yield condition (for a Coulomb-Tresca one, both plane strain and stress are admitted) of incompressible homogeneous isotropic ideal plastic medium, basic relation of principal lines (of curvatures and their ...

Globally convergent method for designing twice spline contractual function

open access: yesJournal of Inequalities and Applications, 2019
To design a quadratic spline contractual function in the case of discretely unknown nodes, a modified constraint shifting homotopy algorithm for solving principal–agent problems is constructed in the paper.
