Extraction of the neutron charge form factor from the charge form factor of deuteron [PDF]
, 2002 We extract the neutron charge form factor from the charge form factor of deuteron obtained from $T_{20}(Q^2)$ data at $0\le Q^2\le$ 1.717 (GeV$^2$). The extraction is based on the relativistic impulse approximation in the instant form of the relativistic

Heterostructure and Q-factor engineering for low-threshold and persistent nanowire lasing
Light: Science & Applications, 2020 Continuous room temperature nanowire lasing from silicon-integrated optoelectronic elements requires careful optimisation of both the lasing cavity Q-factor and population inversion conditions.

Air Damping Analysis of a Micro-Coriolis Mass Flow Sensor
Sensors, 2022 A micro-Coriolis mass flow sensor is a resonating device that measures small mass flows of fluid. A large vibration amplitude is desired as the Coriolis forces due to mass flow and, accordingly, the signal-to-noise ratio, are directly proportional to the

Chiral phase transition in the linear sigma model within Hartree factorization in the Tsallis nonextensive statistics [PDF]
The European Physical Journal A 56, 145 (2020), 2019 We studied chiral phase transition in the linear sigma model within the Tsallis nonextensive statistics in the case of small deviation from the Boltzmann-Gibbs (BG) statistics. The statistics has two parameters: the temperature $T$ and the entropic parameter $q$.

K_l3 form factors at order p^6 in chiral perturbation theory [PDF]
, 2001 This paper describes the calculation of the semileptonic K_l3 decay form factor at order p^6 of chiral perturbation theory which is the next-to-leading order correction to the well-known p^4 result achieved by Gasser and Leutwyler.

Strong factorization property of Macdonald polynomials and higher-order Macdonald's positivity conjecture [PDF]
J. Algebraic Combin., 46 (1), 135-163, 2017, 2016 We prove a strong factorization property of interpolation Macdonald polynomials when $q$ tends to $1$. As a consequence, we show that Macdonald polynomials have a strong factorization property when $q$ tends to $1$, which was posed as an open question in our previous paper with F\'eray. Furthermore, we introduce multivariate $q,t$-Kostka numbers and we

Optics Letters, 2019 An ultra-high sensitive light-induced thermoelastic spectroscopy (LITES) sensor based on a resonant high Q-factor quartz turning fork (QTF) and a Herriot multipass cell was demonstrated for the first time, to the best of our knowledge. The performance of

Capacity Bounds and Degrees of Freedom for MIMO Antennas Constrained by Q-Factor [PDF]
IEEE Transactions on Antennas and Propagation, 2019 The optimal spectral efficiency and the number of independent channels for multiple-input–multiple-output (MIMO) antennas in isotropic multipath channels are investigated when bandwidth requirements are placed on the antenna.

Is coenzyme Q a key factor in aging?
Mechanisms of Ageing and Development, 2010 Coenzyme Q (Q) is a key component for bioenergetics and antioxidant protection in the cell. During the last years, research on diseases linked to Q-deficiency has highlighted the essential role of this lipid in cell physiology. Q levels are also affected during aging and neurodegenerative diseases.
