Enhanced Kondo Effect in an Electron System Dynamically Coupled with Local Optical Phonon

open access: yes, 2007
We discuss Kondo behavior of a conduction electron system coupled with local optical phonon by analyzing the Anderson-Holstein model with the use of a numerical renormalization group (NRG) method.

Fundamental Plane of Black Hole Activity in Quiescent Regime

open access: yes, 2017
A correlation among the radio luminosity ($L_{\rm R}$), X-ray luminosity ($L_{\rm X}$), and black hole mass ($M_{\rm BH}$) in active galactic nuclei (AGNs) and black hole binaries is known to exist and is called the "Fundamental Plane" of black hole ...

A comprehensive study on reference material of Imidacloprid in tomato matrix

open access: yesTạp chí Kiểm nghiệm và An toàn thực phẩm
Controlling the level of crop protection chemical residues in food is always a matter of concern. Certified reference materials (CRM) or reference materials (RM) are used in crop protection chemical residue analysis to validate analytical methods and ...

Lepton flavor violating $\mu\to e\gamma$ and $\mu-e$ conversion in unparticle physics

open access: yes, 2008
We have studied lepton flavor violation processes $\mu\to e\gamma$ and $\mu-e$ conversion in nuclei induced by unparticle. Both ${\rm Br}(\mu\to e\gamma)$ and $\mu-e$ conversion rate ${\rm CR}(\mu-e,{\rm Nuclei})$ strongly depend on the scale dimension ...

Measurements of $R_{\rm b}$ , $A_{\rm FB}^{\rm b}$ , and $A_{\rm FB}^{\rm c}$ in ${\rm e^+ e^-}$ collisions at 130 – 189 GeV [PDF]

open access: yesThe European Physical Journal C, 2000
The cross-section ratio \(R_{\mathrm{b}} = \sigma( \rm e^+ e^- \to{\rm b\overline{\rm b}} )/\sigma(\rm e^+ e^-\to{\mathrm q\bar{\mathrm q}} )\) and the bottom and charm forward-backward asymmetries \(A_{\mathrm{FB}}^{\mathrm{b}}\) and \(A_{\mathrm{FB}}^{\mathrm c}\) are measured using event samples collected by the OPAL detector at centre-of-mass ...

Novel Genetic Risk Factor Identified for L‐Asparaginase‐Induced Pancreatitis in Pediatric Patients With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background L‐asparaginase is a critical component in treatment protocols for pediatric acute lymphoblastic leukemia. Acute pancreatitis reactions can necessitate delays and, in some cases, discontinuation of L‐asparaginase, which compromises outcomes.

MYCN Amplification in RB1‐Inactivated Retinoblastoma: Association With High‐Risk Features

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background MYCN amplification occurs in a subset of retinoblastoma cases, both with and without RB1 inactivation. It has been suggested that retinoblastomas with MYCN amplification represent a distinct entity with more aggressive clinical behavior.
