The QED nonfactorizable correction to the semileptonic charmed three-body B decays

open access: yesEuropean Physical Journal C: Particles and Fields
In this paper, the nonfactorizable photonic corrections to the effective four-fermion vertex for the $$\overline{B}$$ B ¯ $${\rightarrow }$$ → $$D^{({*})}$$ D ( ∗ ) $$+$$ + $${\ell }^{-}$$ ℓ - $$+$$ + $$\bar{\nu }_{\ell }$$ ν ¯ ℓ decays are considered at

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Revisiting the form factors of $$P\rightarrow V$$ P→V transition within the light-front quark models

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We investigate the self-consistency and Lorentz covariance of the covariant light-front quark model (CLF QM) via the matrix elements and form factors ($${{\mathcal {F}}}=g$$ F=g , $$a_{\pm }$$ a± and f) of $$P\rightarrow V$$ P→V transition.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Study on the Υ(1S)→BcM Weak Decays

open access: yesAdvances in High Energy Physics, 2015
Motivated by the prospects of the potential Υ(1S) particle at high-luminosity heavy-flavor experiments, we studied the Υ(1S)→BcM weak decays, where M = π, ρ, K(∗). The nonfactorizable contributions to hadronic matrix elements are taken into consideration

On the stability of AdS backgrounds with λ-deformed factors

open access: yesJournal of High Energy Physics, 2021
We investigate the stability of the non-supersymmetric solutions of type-IIB supergravity having an unwarped AdS factor and λ-deformed subspaces found in [26]. Among the plethora of solutions we study the perturbative stability of backgrounds with an AdS
