Food allergy is the most common cause of anaphylaxis outside the hospital setting. Peanut, tree nuts, milk, egg, and shellfish are the most commonly implicated foods. Most cases of anaphylaxis are reported to occur in the home, but one-fifth of the reactions occur at school or work and a similar proportion in restaurants and other food establishments. Although the majority of reactions in schoo...

A study was performed to elucidate the mechanisms of extinction and autoignition of n-heptane in strained laminar flows under non-premixed conditions. A previously developed detailed mechanism made up of 2540 reversible elementary reactions among 556 species was the starting point for the study. The detailed mechanism was previously used to calculate ignition delay times in homogeneous reactors...

The energy dependence of the total kaon production cross sections in baryon baryon (N and ∆) collisions are studied in the resonance model, which is a relativistic, tree-level treatment. This study is the first attempt to complete a systematic, consistent investigation of the elementary kaon production reactions for both the pion baryon and baryon baryon reactions. Our model suggests that the m...

The kinetics of the elementary reactions involved in the low-temperature combustion of alkanes are reviewed. The reactions are centred on the alkyl radical and its decomposition, recombination and reactions with 0,. A combination of theory, modelling and direct measurements, using especially laser flash photolysis, have played key roles in the characterisation of all three reaction types. A rem...

We propose a novel statistical learning framework for automatically and efficiently building reduced kinetic Monte Carlo (KMC) models of large-scale elementary reaction networks from data generated by a single or few molecular dynamics simulations (MD). Existing approaches for identifying species and reactions from molecular dynamics typically use bond length and duration criteria, where bond d...

A modern approach to model chemically reactive systems is to use a set of elementary reactions relating all chemical species which are involved in the chemical system. This detailed modeling leads to rather large systems of differentialalgebraic equations to be treated numerically. This paper presents a new algorithm based on partially reduced SQP methods for the computation of optimal controls...

While the vacuum properties of most hadrons are known to reasonable accuracy today, it is a much-debated question how these properties change in nuclear matter. In particular for the light vector mesons there have been various theoretical predictions regarding their in-medium properties. One of the expected in-medium effects is the so-called ’collisinal broadening’ of the meson spectral functio...

Photocatalytic reactions have been defined as those processes that require both a (not consumed) catalyst and light. A previous definition was whether such reactions brought a system towards or away from the (thermal) equilibrium. This consideration brings in the question whether a part of the photon energy is incorporated into the photochemical reaction products. Data are provided for represen...

A diffusion-limited aggregation process, in which clusters coalesce by means of 3-particle reaction, A + A + A → A, is investigated. In one dimension we give a heuristic argument that predicts logarithmic corrections to the mean-field asymptotic behavior for the concentration of clusters of mass m at time t, C m (t) ∼ m −1/2 (log(t)/t) 3/4 , for 1 ≪ m ≪ t/ log(t). The total concentration of clu...
