The decays of $$\bar{B}^0$$ B¯0 , $$\bar{B}^0_s$$ B¯s0 and $$B^-$$ B- into $$\eta _c$$ ηc plus a scalar or vector meson

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We investigate the decays of $$\bar{B}^0_s$$ B¯s0 , $$\bar{B}^0$$ B¯0 and $$B^-$$ B- into $$\eta _c$$ ηc plus a scalar or vector meson in a theoretical framework by taking into account the dominant process for the weak decay of $$\bar{B}$$ B¯ meson into $

Are the anti-charmed and bottomed pentaquarks molecular heptaquarks?

open access: yes, 2004
I study the charmed $uudd\bar c$ resonance D*p (3100) very recently discovered by the H1 collaboration at Hera. An anticharmed resonance was already predicted, in a recent publication mostly dedicated to the S=1 resonance Theta+(1540).

CP Violation and the Absence of Second Class Currents in Charmless B Decays [PDF]

open access: yes, 2001
The absence of second class currents together with the assumption of factorization for non-leptonic B decays provide new constraints on CP observables in decay B to a0(980)(to eta pi) pi. The kinematics of this decay do not allow interference between the

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

open access: yesFEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Study of Exclusive B decays to Charmed Baryons

open access: yes, 2002
Using 29.1fb-1 of data accumulated at the Upsilon(4S) with the Belle detector at KEKB, we have studied the decay modes B0bar->Lambda_c+ pbar pi+pi-, B- -> Lambda_c+ pbar pi-, and B0bar ->Lambda_c+ pbar. We report branching fractions of exclusive B decays

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Observations of the singly Cabibbo-suppressed decays Ξ c + → p K S 0 $$ {\Xi}_c^{+}\to p{K}_S^0 $$ , Ξ c + → Λ π + $$ {\Xi}_c^{+}\to \Lambda {\pi}^{+} $$ , and Ξ c + → Σ 0 π + $$ {\Xi}_c^{+}\to {\Sigma}^0{\pi}^{+} $$ at Belle and Belle II

open access: yesJournal of High Energy Physics
Using data samples of 983.0 fb −1 and 427.9 fb −1 accumulated with the Belle and Belle II detectors operating at the KEKB and SuperKEKB asymmetric-energy e + e − colliders, singly Cabibbo-suppressed decays Ξ c + → p K S 0 $$ {\Xi}_c^{+}\to p{K}_S^0 ...

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Measurements of the branching fractions of $${\Xi }_{c}^{+}\to {\Sigma }^{+}{K}_{S}^{0}$$ , $${\Xi }_{c}^{+}\to {\Xi }^{0}{\pi }^{+}$$ , and $${\Xi }_{c}^{+}\to {\Xi }^{0}{K}+$$ at Belle and Belle II

open access: yesJournal of High Energy Physics
Using 983.0 fb −1 and 427.9 fb −1 data samples collected with the Belle and Belle II detectors at the KEKB and SuperKEKB asymmetric energy e + e − colliders, respectively, we present studies of the Cabibbo-favored $${\Xi }_{c}^{+}$$ decays $${\Xi }_{c}^{+
