Rapid prediction of NMR spectral properties with quantified uncertainty [PDF]

, 2018
open access articleAccurate calculation of specific spectral properties for NMR is an important step for molecular structure elucidation. Here we report the development of a novel machine learning technique for accurately predicting chemical shifts of ...

Multi-criteria decision making in civil engineering: Part I – a state-of-the-art survey

Engineering Structures and Technologies, 2016
For several decades, multi-criteria decision-making (MCDM) methods have been in use to address issues particular to design, organisation and management of constructions.

Coupling and higher-order effects in the 12C(d,p)13C and 13C(p,d)12C reactions

, 2005
Coupled channels calculations are performed for the 12C(d,p)13C and 13C(p,d)12C reactions between 7 and 60 MeV to study the effect of inelastic couplings in transfer reactions.

Exogenous GA3 alleviates low nitrogen stress by enhancing leaf nitrogen assimilation and limiting the transport of photosynthates to roots in apple plants

Fruit Research
Gibberellins (GAs) are crucial for improving plant adaptation to abiotic stresses; however, their physiological functions in apple plants under low-nitrogen (N) stress remain unclear. In this work, a hydroponic approach was used to explore the effects of

Clustering in 13C [PDF]

EPJ Web of Conferences
Measurement was conducted at the INFN-LNL, employing a Tandem accelerator to achieve a 95 MeV 14N beam focused on 10B target (201 µg/cm²) with the aim to explore the cluster structures of light carbon isotopes.

13C n.m.r. investigation on the nitrogen methylation of some azabenzenes [PDF]

, 1977
The 1H and 13C n.m.r. spectra of N-methylated pyridine, pyridazine, pyrimidine and pyrazine and N,N-dimethylated pyrimidine and pyrazine have been recorded and analysed.

Probing rapid carbon fixation in fast-growing seaweed Ulva meridionalis using stable isotope 13C-labelling

Scientific Reports, 2020
The high growth rate of Ulva seaweeds makes it a potential algal biomass resource. In particular, Ulva meridionalis grows up to fourfold a day. Here, we demonstrated strong carbon fixation by U.

Molecular particle-core model and its application to 13C-13C scattering [PDF]

, 2006
On the basis of the two-center shell model a theory is developed for the excitation of loosely bound nucleons in heavy ion collisions. These nucleons move in the two-center shell model potential generated by all the nucleons and are described by ...

Carbon-13 n.m.r. investigation on the nitrogen methylation of the mono- and diazanaphthalenes [PDF]

, 1977
The 13C n.m.r. spectra of the N-methylated mono- and diazanaphthalenes have been recorded and analysed. It has been shown that N-methylation as well as N-protonation in cinnoline occur predominantly at the -nitrogen atom.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,
