l-doublet splittings in Δ vibrational state of 15N14N16O isotopomer
Chemical Physics Impact, 2021 We report the direct experimental evidences of l-doublet fine splittings between the parity doublet e and f sub-states of β-site isotopomer of nitrous oxide (15N14N16O) in the (1220)←(0220) ro-vibrational transition for l = 2 (i.e.

Double Split-Ring Resonator for Dielectric Constant Measurement of Solids and Liquids [PDF]
Journal of Electromagnetic Engineering and Science, 2022 This study proposes a 2.45-GHz double split-ring resonator for measuring the dielectric constant in both solids and liquids. Two concentric rectangular rings with asymmetric splits are used in the proposed resonator to achieve a high-quality factor for ...

International Journal of Analytical Chemistry, 2014 The acid dissociation constants of potential bioactive fused ring thiohydantoin-pyrrolidine compounds were determined by potentiometric titration in 20% (v/v) ethanol-water mixed at 25±0.1°C, at an ionic background of 0.1 mol/L of NaCl using the ...

Gauge invariants, correlators and holography in bosonic and fermionic tensor models
Journal of High Energy Physics, 2017 Motivated by the close connection of tensor models to the SYK model, we use representation theory to construct the complete set of gauge invariant observables for bosonic and fermionic tensor models. Correlation functions of the gauge invariant operators

Sensors, 2015 A series of rhodamine derivatives L1–L3 have been prepared and characterized by IR, 1H-NMR, 13C-NMR and ESI-MS. These compounds exhibited selective and sensitive “turn-on” fluorescent and colorimetric responses to Al3+ in methanol.

A variant of the large sieve inequality with explicit constants
Journal of Mathematical Cryptology, 2020 We give an effective version with explicit constants of the large sieve inequality for imaginary quadratic fields. Explicit results of this kind are useful for estimating the computational complexity of algorithms which generate elements, whose norm is a

On the ring of constants for derivations of power series rings in two variables [PDF]
Colloquium Mathematicum, 2001 Summary: Let \(k[[x,y]]\) be the formal power series ring in two variables over a field \(k\) of characteristic zero and let \(d\) be a non-zero derivation of \(k[[x,y]]\). We prove that if \(\text{Ker}(d)\neq k\) then \(\text{Ker}(d) = \text{Ker}(\delta)\), where \(\delta\) is a Jacobian derivation of \(k[[x,y]]\).
