Search for excited B c + states

open access: yesJournal of High Energy Physics, 2018
A search is performed in the invariant mass spectrum of the B c +π+π− system for the excited B c + states B c (21 S 0)+ and B c (23 S 1)+ using a data sample of pp collisions collected by the LHCb experiment at the centre-of-mass energy of s=8 $$ \sqrt{s}

Effects of the excited states on electron kinetics and power absorption and dissipation in inductively coupled Ar plasmas

open access: yesAIP Advances, 2022
The effects of the excited states on electron kinetics as well as plasma power absorption and dissipation are numerically studied in radio frequency low-pressure inductively coupled Ar plasmas.

Exciting dark matter in the galactic center

open access: yes, 2010
We reconsider the proposal of excited dark matter (DM) as an explanation for excess 511 keV gamma rays from positrons in the galactic center. We quantitatively compute the cross section for DM annihilation to nearby excited states, mediated by exchange ...

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

open access: yesFEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Estimating Molecular Thermal Averages with the Quantum Equation of Motion and Informationally Complete Measurements

open access: yesEntropy
By leveraging the Variational Quantum Eigensolver (VQE), the “quantum equation of motion” (qEOM) method established itself as a promising tool for quantum chemistry on near-term quantum computers and has been used extensively to estimate molecular ...

Inclusion of the excited states quark propagator to the nucleon electromagnetic form factors in the perturbative chiral quark model

open access: yesResults in Physics, 2020
Electromagnetic form factors of the nucleon are studied within the framework of the Perturbative Chiral Quark Model (PCQM). In a previous analysis of the nucleon electromagnetic form factors, the quark propagator used in the calculation was truncated to ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Microscopic Parameters in the Excited State of Toluene and Some of Its Haloderavatives [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2010
The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined.

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

open access: yesMolecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Unrevealing mechanism of the thermal tautomerization of avobenzone by means of quantum chemical computations [PDF]

open access: yesJournal of the Serbian Chemical Society, 2016
Avobenzone (4-tert-butyl-4’-methoxydibenzoylmethane) is one of the most widely used UVA filters in cosmetic sunscreens. Reactivity of avobenzone is complex and challenging to understand, due to a presence of transient tautomers.
