Theoretical study on the mechanism of the cycloaddition reaction between ketenimine and hydrogen cyanide [PDF]

open access: yesJournal of the Serbian Chemical Society, 2016
The cycloaddition reaction mechanism between interstellar molecules ketenimine and HCN has been investigated employing the second-order Møller-Plesset perturbation theory (MP2) method in order to better understand the reactivity of nitrogenous ...

Applicability of Anticancer Drugs for the Triple-Negative Breast Cancer Based on Homologous Recombination Repair Deficiency

open access: yesFrontiers in Cell and Developmental Biology, 2022
Triple-negative breast cancer (TNBC) is a highly aggressive disease with historically poor outcomes, primarily due to the lack of effective targeted therapies. Here, we established a drug sensitivity prediction model based on the homologous recombination

Tidally perturbed oblique pulsations in the hierarchical triple system V1031 Orionis [PDF]

open access: yesPublications of the Astronomical Society of Japan, 2021
Abstract We present Transiting Exoplanet Survey Satellite (TESS) photometry of the triple star system V1031 Ori (AB)C, which exhibits short-period oscillations superimposed on an eclipsing light curve.The high-quality data were analyzed in detail and combined with the published spectroscopic measurements to obtain the fundamental stellar

Perturbation Methods for the Eigencharacteristics of Symmetric and Asymmetric Systems

open access: yesShock and Vibration, 2018
Dynamic analysis for a vibratory system typically begins with an evaluation of its eigencharacteristics. However, when design changes are introduced, the eigensolutions of the system change and thus must be recomputed.

New series representations for the two-loop massive sunset diagram

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We derive new convergent series representations for the two-loop sunset diagram with three different propagator masses $$m_1,\, m_2$$ m1,m2 and $$m_3$$ m3 and external momentum p by techniques of analytic continuation on a well-known triple series that ...

Systems Pharmacology and Rational Polypharmacy: Nitric Oxide-Cyclic GMP Signaling Pathway as an Illustrative Example and Derivation of the General Case. [PDF]

open access: yesPLoS Computational Biology, 2016
Impaired nitric oxide (NO˙)-cyclic guanosine 3', 5'-monophosphate (cGMP) signaling has been observed in many cardiovascular disorders, including heart failure and pulmonary arterial hypertension. There are several enzymatic determinants of cGMP levels in

Epsin deficiency impairs endocytosis by stalling the actin-dependent invagination of endocytic clathrin-coated pits

open access: yeseLife, 2014
Epsin is an evolutionarily conserved endocytic clathrin adaptor whose most critical function(s) in clathrin coat dynamics remain(s) elusive. To elucidate such function(s), we generated embryonic fibroblasts from conditional epsin triple KO mice.

Wirtinger-Type Inequality and the Stability Analysis of Delayed Lur'e System

open access: yesDiscrete Dynamics in Nature and Society, 2013
This paper proposes a new delay-depended stability criterion for a class of delayed Lur'e systems with sector and slope restricted nonlinear perturbation.

Observational Detection of Higher-Order Secular Perturbations in Tight Hierarchical Triple Stars

open access: yesUniverse, 2023
In this work, we search for observational evidence of higher-order secular perturbations in three eclipsing binaries. These are slightly eccentric binaries, and they form the inner pairs of tight, compact, hierarchical triple star systems. Simultaneously, we analyze the high-precision satellite (Kepler and TESS) light curves; eclipse timing variations;
