Comparative study of the requantization of the time-dependent mean field for the dynamics of nuclear pairing

open access: yes, 2018
To describe quantal collective phenomena, it is useful to requantize the time-dependent mean-field dynamics. We study the time-dependent Hartree-Fock-Bogoliubov (TDHFB) theory for the two-level pairing Hamiltonian, and compare results of different ...

Racial intermarriage pairings [PDF]

open access: yesDemography, 2001
AbstractMost studies of racial intermarriage rely on the prevalence of intermarriage to measure the strength of group boundaries, without scrutinizing the nature of intermarriage pairings. Examination of intermarried couples’ characteristics reveals (1) that intermarriages and endogamous marriages follow different patterns, and (2) that intermarriage ...

Pair-to-Pair Peer Learning [PDF]

open access: yes2020 ASEE Virtual Annual Conference Content Access Proceedings, 2020
In this work, pair-to-pair peer learning (PPPL) as the simplest form of group-to-group peer learning (GGPL) is defined. GGPL is defined as a learning method where two or more peer groups interact to increase the knowledge of all members; while PPPL is defined as GGPL with group sizes of only two members each.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Microscopic study of the difference in mirror pair nuclei from Z = 8 to Z = 50 in the framework of HFB theory

open access: yesJournal of Taibah University for Science
Differences in ground-state properties of mirror pair nuclei from Oxygen (Z = 8) to Tin (Z = 50) have been investigated in the framework of Skyrme Hartree–Fock–Bogoliubov using HFBTHO computer code V3.00 with both harmonic oscillator (HO) and transformed

Effect of pairing on one- and two-nucleon transfer below the Coulomb barrier: a time-dependent microscopic description

open access: yes, 2012
The effect of pairing correlation on transfer reaction below the Coulomb barrier is investigated qualitatively and quantitatively using a simplified version of the Time-Dependent Hartree-Fock + BCS approach.

PAIRED ACCELERATED FRAMES [PDF]

open access: yesInternational Journal of Modern Physics A, 1996
The geometrical and quantum-mechanical basis for Davies’ and Unruh’s acceleration temperature is traced to a type of quantum-mechanical (“achronal”) spin. Its existence and definition are based on pairs of causally disjoint accelerated frames. For bosons the expected spin vector of monochromatic particles is given by the “Planckian power” and the “r.m.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Self-pairings on hyperelliptic curves

open access: yesJournal of Mathematical Cryptology, 2013
A self-pairing is a pairing computation where both inputs are the same group element. Self-pairings are used in some cryptographic schemes and protocols. In this paper, we show how to compute the Tate–Lichtenbaum pairing on a curve more efficiently than

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
