Inclusive Photoproduction of D* Mesons with Massive Charm Quarks [PDF]

open access: yes, 2003
We have calculated the next-to-leading order cross sections for the inclusive production of D* mesons in gamma-p collisions at HERA in two approaches using massive or massless charm quarks. The usual massive theory for the direct cross section with charm

Regulation of Tissue Inflammation by 12-Lipoxygenases

open access: yesBiomolecules, 2021
Lipoxygenases (LOXs) are lipid metabolizing enzymes that catalyze the di-oxygenation of polyunsaturated fatty acids to generate active eicosanoid products. 12-lipoxygenases (12-LOXs) primarily oxygenate the 12th carbon of its substrates.

The M06 suite of density functionals for main group thermochemistry, thermochemical kinetics, noncovalent interactions, excited states, and transition elements: two new functionals and systematic testing of four M06-class functionals and 12 other functionals

open access: yes, 2008
We present two new hybrid meta exchange- correlation functionals, called M06 and M06-2X. The M06 functional is parametrized including both transition metals and nonmetals, whereas the M06-2X functional is a high-nonlocality functional with double the ...

Measurement of the Strong Coupling alpha s from Four-Jet Observables in e+e- Annihilation [PDF]

open access: yes, 2006
Data from e+e- annihilation into hadrons at centre-of-mass energies between 91 GeV and 209 GeV collected with the OPAL detector at LEP, are used to study the four-jet rate as a function of the Durham algorithm resolution parameter ycut. The four-jet rate

Construction of Escherichia coli K-12 in-frame, single-gene knockout mutants: the Keio collection

open access: yesMolecular Systems Biology, 2006
We have systematically made a set of precisely defined, single‐gene deletions of all nonessential genes in Escherichia coli K‐12. Open‐reading frame coding regions were replaced with a kanamycin cassette flanked by FLP recognition target sites by using a

Automatic diagnosis of the 12-lead ECG using a deep neural network [PDF]

open access: yesNature Communications, 2019
The role of automatic electrocardiogram (ECG) analysis in clinical practice is limited by the accuracy of existing models. Deep Neural Networks (DNNs) are models composed of stacked transformations that learn tasks by examples.

Mutational landscape and significance across 12 major cancer types

open access: yesNature, 2013
The Cancer Genome Atlas (TCGA) has used the latest sequencing and analysis methods to identify somatic variants across thousands of tumours. Here we present data and analytical results for point mutations and small insertions/deletions from 3,281 tumours

Assessment of pain in newborns during immunization by using a scoring system [PDF]

open access: yesSestrinska reč, 2015
Introduction: The inability of the newborn to independently express words of my pain significantly contributes to the lack of recognition of presence and inadequate treatment of pain.

Spin Polarizabilities of the Nucleon from Polarized Low Energy Compton Scattering

open access: yes, 2003
As guideline for forthcoming experiments, we present predictions from Chiral Effective Field Theory for polarized cross sections in low energy Compton scattering for photon energies below 170 MeV, both on the proton and on the neutron.
