Rotational spectrum of cis–cis HOONO [PDF]
, 2004 The pure rotational spectrum of cis-cis peroxynitrous acid, HOONO, has been observed. Over 220 transitions, sampling states up to J(')=67 and K-a(')=31, have been fitted with an rms uncertainty of 48.4 kHz.

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.

Quantum cohomology of the Lagrangian Grassmannian
, 2003 Let V be a symplectic vector space and LG be the Lagrangian Grassmannian which parametrizes maximal isotropic subspaces in V. We give a presentation for the (small) quantum cohomology ring QH^*(LG) and show that its multiplicative structure is determined

The puzzle conjecture for the cohomology of two-step flag manifolds [PDF]
, 2016 We prove a conjecture of Knutson asserting that the Schubert structure constants of the cohomology ring of a two-step flag variety are equal to the number of puzzles with specified border labels that can be created using a list of eight puzzle pieces. As

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.

Generators of rings of constants for some diagonal derivations in polynomial rings
Journal of Pure and Applied Algebra, 1995 Let \(K\) be a field of characteristic zero. The authors show that if \(n\geq 3\), that given \(r\geq 0\) there exists a diagonal \(K\)-derivation of \(K[x_1, \dots, x_n]\) such that the minimal number of generators over \(K\) of the ring of constants is equal to \(r\).

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

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

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
