Replication Protein A (RPA) Phosphorylation Prevents RPA Association with Replication Centers [PDF]

Molecular and Cellular Biology, 2004
Mammalian replication protein A (RPA) undergoes DNA damage-dependent phosphorylation at numerous sites on the N terminus of the RPA2 subunit. To understand the functional significance of RPA phosphorylation, we expressed RPA2 variants in which the phosphorylation sites were converted to aspartate (RPA2(D)) or alanine (RPA2(A)).

Using software based on the Monte-Carlo method for receiving the few-group homogenized macroscopic interaction cross-section

Trudy Odesskogo Politehničeskogo Universiteta, 2017
The constant preparation issues are important for performing the few-group analysis for different states of the reactor core. Besides, the constant preparation method influences the further calculations accuracy and quality.

Collapse of the random phase approximation: examples and counter-examples from the shell model

, 2009
The Hartree-Fock approximation to the many-fermion problem can break exact symmetries, and in some cases by changing a parameter in the interaction one can drive the Hartree-Fock minimum from a symmetry-breaking state to a symmetry-conserving state (also

RPA

, 2023
This work proposes a fast solution algorithm to a fundamental data science problem, namely to identify Boolean rules in disjunctive normal form (DNF) that classify samples based on binary features. The algorithm is an explainable machine learning method: it provides an explicit input-output relationship.

RPA vs. exact shell-model correlation energies

, 2002
The random phase approximation (RPA) builds in correlations left out by mean-field theory. In full 0-hbar-omega shell-model spaces we calculate the Hartree-Fock + RPA binding energy, and compare it to exact diagonalization. We find that in general HF+RPA

Application of the RPA and Higher RPA to the V and T States of Ethylene [PDF]

The Journal of Chemical Physics, 1971
We have applied our proposed higher random-phase approximation (HRPA) to the T and V states of ethylene. In the HRPA, unlike the RPA, one solves for the excitation frequencies and the ground-state correlations self-consistently. We also develop a simplified scheme (SHRPA) for solving the equations of the HRPA, using only molecular integrals sufficient ...

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity

Molecular Oncology, EarlyView.
Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a

Semi-mechanistic Model Applied to the Search for Economically Optimal Conditions and Blending of Gasoline Feedstock for Steam-cracking Process

MATEC Web of Conferences, 2016
Steam-cracking is energetically intensive large-scaled process which transforms a wide range of hydrocarbons feedstock to petrochemical products. The dependence of products yields on feedstock composition and reaction conditions has been successfully ...
