Identification of rice samples with rice blast resistance genes Pi-2 and Pi-b

open access: yesGrain Economy of Russia
Since rice blast is a disease that causes significant damage to rice all over the world, the intensive development of disease-resistant genotypes is of great urgency. The use of molecular biology technologies, new biotechnological approaches and molecular genetic methods allows creating disease-resistant varieties while reducing the time of their ...

Weak Phase $\gamma$ From Ratio of $B \to K \pi$ Rates

open access: yes, 1998
The ratio of partial decay rates for charged and neutral $B$ mesons to $K \pi$ final states provides information on the weak phase $\gamma \equiv {\rm Arg} (V_{ub}^*)$ when augmented with information on the CP-violating asymmetry in the $K^\pm \pi^\mp ...

Observation of the B c + → J / ψ π + π 0 $$ {B}_c^{+}\to J/\psi {\pi}^{+}{\pi}^0 $$ decay

open access: yesJournal of High Energy Physics
The first observation of the B c + → J / ψ π + π 0 $$ {B}_c^{+}\to J/\psi {\pi}^{+}{\pi}^0 $$ decay is reported with high significance using proton-proton collision data, corresponding to an integrated luminosity of 9 fb −1, collected with the LHCb ...

Antiretroviral Therapy with Ritonavir-Boosted Atazanavir- and Lopinavir-Containing Regimens Correlates with Diminished HIV-1 Neutralization

open access: yesVaccines
Background/Objectives: The impact of virion maturation on neutralizing antibody responses in HIV treatment is not fully understood. This study examines whether antiretroviral regimens (ART) with boosted protease inhibitors (b-PI), which increase exposure

Molecular screening for the presence of Magnaporthe oryzae resistance Pi-b gene in rice hybrids

open access: yesBIO Web of Conferences
Blast is a rice disease that affects all above-ground parts of the plant, such as nodes, stems, panicles, leaves, etc. Damage to these plant organs negatively affects the developmental stage, that is, the growing season of the plant. As a result, it is the reason for the formation of puny seeds and decreased productivity.

Search for the B c + $$ {B}_c^{+} $$ → χ c1(3872)π + decay

open access: yesJournal of High Energy Physics
A search for the decay B c + $$ {B}_c^{+} $$ → χ c1(3872)π + is reported using proton-proton collision data collected with the LHCb detector between 2011 and 2018 at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity ...

Proteomics reveals the significance of vacuole Pi transporter in the adaptability of Brassica napus to Pi deprivation

open access: yesFrontiers in Plant Science
Vacuolar Pi transporters (VPTs) have recently been identified as important regulators of cellular Pi status in Arabidopsis thaliana and Oryza sativa. In the oil crop Brassica napus, BnA09PHT5;1a and BnC09PHT5;1a are two homologs of AtPHT5;1, the vacuolar

Detecting induced subgraphs [PDF]

open access: yes
An s-graph is a graph with two kinds of edges : subdivisible edges and real edges. A realisation of an s-graphB is any graph obtained by subdividing subdivisible edges of B into paths of arbitrary length (at least one).

B -> pi, B(s) -> K form factors and Vub determination

open access: yes, 2008
We present a QCD light-cone sum rule (LCSR) estimation of the B -> pi, B -> K, and Bs -> K form factors calculating gluon radiative corrections at next-to-leading order. The MS-bar b-quark mass is used, instead of the one-loop pole mass employed in the previous analyses.

Polarization and quantum entanglement effects in $$B^\pm _c\rightarrow J/\psi +\pi ^\pm +\pi ^0$$ B c ± → J / ψ + π ± + π 0 process

open access: yesEuropean Physical Journal C: Particles and Fields
Motivated by the very recent observation of the $$B^+_c\rightarrow J/\psi +\pi ^+ +\pi ^0$$ B c + → J / ψ + π + + π 0 decay using proton–proton collision data by the LHCb collaboration, we study the four-body angular distributions and the quantum ...
