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

Molecules, 2021 We report the observation and analysis of the rotational spectrum of a 1:1 cluster between 2-aminopyridine and water (AMW) carried out with supersonic expansion Fourier transform microwave spectroscopy at 4.7–16.5 GHz. Measurements of the 2-aminopyridine

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 \(k[[x,y]]\).

The chiral ring of a symmetric orbifold and its large N limit
Journal of High Energy Physics, 2023 We analyze the chiral operator ring of the symmetric orbifold conformal field theory on the complex two-plane ℂ2. We compute the large N limit of the ring and exhibit its factorized leading order behaviour.

Influence of per-O-sulfation upon the conformational behaviour of common furanosides
Beilstein Journal of Organic Chemistry, 2019 The studies on the recently discovered pyranoside-into-furanoside rearrangement have led us to conformational investigations of furanosides upon their total sulfation.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Potentiometric investigation of acid-base equilibria of two new pyrimidine derivatives in various methanol-water media [PDF]
Journal of the Serbian Chemical Society, 2006 The acid-base properties of 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-one (L1) and 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-thione (L2) were investigated potentiometrically at an ionic strength of 0.10M(LiCl) in 19.8, 33.6 and 55.9 % (v/v) methanol ...

Tạp chí Khoa học Đại học Đà Lạt, 2022 We demonstrate in this study that near-zero, ultra-flattened chromatic dispersion can be achieved over a wide range of wavelengths in photonic crystal fibers (PCFs) by means of slight variations in the geometrical parameters of the cladding.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
