Study of Even-Even∕Odd-Even∕Odd-Odd Nuclei in Zn-Ga-Ge Region in the Proton-Neutron IBM∕IBFM∕IBFFM

AIP Conference Proceedings, 2009
We study the even‐even, odd‐even and odd‐odd nuclei in the region including Zn‐Ga‐Ge in the proton‐neutron IBM and the models derived from it: IBM2, IBFM2, IBFFM2. We describe 67Ga, 65Zn, and 68Ga by coupling odd particles to a boson core 66Zn. We also calculate the β+‐decay rates among 68Ge, 68Ga and 68Zn.

TheK=3/2 1 + side-band in99Y and its description by the IBFM/PTQM model

Zeitschrift Für Physik A, Atomic Nuclei, 1986
The K=3/21T rotational band has been identified in99Y with a band-head energy of 536 keV. This result is in contradiction with previously reported data, but is in agreement with predictions of the IBFM/PTQM model.

IBFM: An Instance-weight Balanced Factorization Machine for Sparse Prediction

2021 International Conference on Data Mining Workshops (ICDMW), 2021
The prediction accuracy rate of user response prediction tasks has significant practical implications. A slight improvement in this metrics can lead to a significant gain of commercial value for real-world applications.

Vers une description unifiée de la structure nucléaire : Modèles IBM, IBFM et supersymétries

Annales De Physique, 1983
This article is a review of the models introduced recently for the description of low-lying collective states in nuclei in terms of interacting bosons. The general basic ideas underlying the IBM (even-even nuclei) and IBFM (odd-even nuclei) models are first given, outlining some simple analytical results obtained using group theory.

Phase transition studies of the odd-mass 123−135Xe isotopes based on SU(1,1) algebra in IBFM

International Journal of Modern Physics E, 2016
In this paper, we have investigated the positive-parity states in the odd-mass transitional [Formula: see text]Xe isotopes within the framework of the interacting boson–fermion model. Two solvable extended transitional Hamiltonians which are based on SU(1,1) algebra are employed to provide an investigation of quantum phase transition (QPT) between the

Level structure of 123Cs observed from 123Ba decay and described using the IBFM and CQPC models

The European Physical Journal A, 2000
The decay of 123Ba to 123Cs has been studied with mass-separated sources. Singles spectra of γ-rays, X-rays and conversion electrons as well as γ - γ - t, γ - e − - t, and X - e − - t coincidences were recorded. A level scheme of 123Cs has been constructed including 26 new excited states and 82 transitions. The existence

DOWN'S Syndrome Acute Lymphoblastic LEUKEMIA: A HIGHLY Heterogeneous DISEASE DRIVEN by an Aberrant CRLF2/JAK2 Cooperation – A REPORT FROM the Ibfm-STUDY GROUP.

Blood, 2009
Abstract Abstract 11 Children with Down's Syndrome (DS) have an increased risk for acute lymphoblastic leukemia (ALL). We have previously identified somatic mutations in R683 of JAK2 in 20% of DS-ALLs (Bercovich et al, Lancet 2008;372:1484).

Group theoretical aspects ofU B(6) ⊗U F(20) symmetry limits of IBFM related to theU B(5) andO B(6) limits of IBM

Pramana, 1997
TheU B(6)⊗U F(20) Bose-Fermi dynamical symmetry of interacting boson-fermion model arises when the odd nucleon occupies single particle orbits withj=1/2, 3/2, 5/2, and 7/2. The subgroup structures ofU B(6)⊗U F(20) related to theU B(5) andO B(6) limits of sdIBM (U B(6)) are analysed. Broadly speaking,U B(6)⊗U F(20) admitsU BF(5)⊗U s F (4), SpinBF(5)⊗U k
