Photochemical oxidative cyclisation of stilbenes and stilbenoids : the Mallory-reaction
(Journal article; Peer reviewed, 2011-06-14)After Mallory described in 1964 the use of iodine as catalyst for the photochemical cyclisation of stilbenes, this reaction has proven its effectiveness in the synthesis of phenanthrenes, other PAHs and phenacenes with a ... -
Photochemical synthesis of chrysenols
(Peer reviewed; Journal article, 2008-08)Chrysenols are formed together with other metabolites when chrysene is metabolized in living organisms. The principal metabolites are needed as pure compounds for reference materials and standards to study various aspects ... -
PLATINUM SENSITIVE 2 LIKE impacts growth, root morphology, seed set, and stress responses
(Journal article; Peer reviewed, 2017-07)Eukaryotic protein phosphatase 4 (PP4) is a PP2A-type protein phosphatase that is part of a conserved complex with regulatory factors PSY2 and PP4R2. Various lines of Arabidopsis thaliana with mutated PP4 subunit genes ... -
Primordial Gravitational Waves with LISA
(Journal article; Peer reviewed, 2017)Primordial Gravitational Waves are the next target of modern cosmology. They represent a window on the early Universe and the only probe of the physics and microphysics of the inflationary period. When the production of ... -
Pseudo-Riemannian VSI spaces
(Journal article; Peer reviewed, 2011)In this paper we consider pseudo-Riemannian spaces of arbitrary sig- nature for which all of their polynomial curvature invariants vanish (VSI spaces). We discuss an algebraic classification of pseudo-Riemannian spaces ... -
Pseudo-Riemannian VSI spaces II
(Journal article; Peer reviewed, 2012)In this paper we consider pseudo-Riemannian spaces of arbitrary signature for which all of the polynomial curvature invariants vanish (VSI spaces). Using an algebraic classification of pseudo-Riemannian spaces in terms of ... -
Regiospesific synthesis of dimethylphenanthrenes
(Peer reviewed; Journal article, 2017-05)The dimethylated phenanthrenes 2,3-dimethylphenanthrene (4a), 2,7-dimethylphenanthrene (4b), 2,6-dimethylphenanthrene (4c) and 1,7-dimethylphenanthrene (4d) have been prepared in gram-quantities by a short sequence of ... -
A review of the monophyly and composition of the Bengaliinae with the description of a new genus and species, and new evidence for the presence of Melanomyinae in the Afrotropical Region (Diptera, Calliphoridae)
(Book; Peer reviewed, 2011)Mafikengia ciliata gen. nov., sp. nov. is described from South Africa and assigned to the subfamily Bengaliinae of the Calliphoridae. It is recognisable by its small size (4 mm), mostly yellow body, and a number of peculiar ... -
Revision of the Afrotropical species of the Bengalia peuhi species-group, including a species reassigned to the B. spinifemorata species-group (Diptera, Calliphoridae), with notes on the identity of Ochromyia petersiana Loew, 1852 (Diptera, Rhiniidae)
(Book; Peer reviewed, 2012)Eleven Afrotropical species of Bengalia Robineau-Desvoidy, ten in the Bengalia peuhi species-group and one reassigned to the Bengalia spinifemorata species-group, are revised. The male genitalia of all, and the ovipositor ... -
Revision of the Bengalia spinifemorata species-group (Diptera, Calliphoridae)
(Journal article; Peer reviewed, 2011)The Afrotropical Bengalia spinifemorata species-group is revised and their male genitalia illustrated by means of digital colour photography. Six species are recognized and keyed, and their geographical distribution ... -
Revision of the cluster flies of the Pollenia haeretica species-group (Diptera, Calliphoridae)
(Journal article; Peer reviewed, 2010-06-09)The Palaearctic Pollenia haeretica species-group is revised. Two species make up the group: Pollenia haeretica Séguy, 1928 (Algeria, Tunisia, Italy) and Pollenia ibalia Séguy, 1930 (Morocco). Pollenia rungsi Séguy, 1953 ... -
Revision of the Oriental species of the Bengalia peuhi speciesgroup (Diptera, Calliphoridae)
(Peer reviewed; Book; Journal article, 2009-10-08)The Oriental species of the Bengalia peuhi species-group are revised and their male genitalia illustrated by means of digital colour photography. A key to males is presented, complete synonymies are given for all the species ... -
Ricci nilsoliton black holes
(Journal article; Peer reviewed, 2008)We follow a constructive approach and find higher-dimensional black holes with Ricci nilsoliton horizons. The spacetimes are solutions to the Einstein equation with a negative cosmological constant and generalise therefore, ... -
Semi-algebraic optimization of temperature compensation in a general switch-type negative feedback model of circadian clocks
(Journal article; Peer reviewed, 2008)Temperature compensation is an essential property of circadian oscillators which enables them to act as physiological clocks. We have analyzed the temperature compensating behavior of a generalized transcriptional–translational ... -
Sensitivity analysis of a pathway with respect to fast and small temperature change
(Journal article; Peer reviewed, 2019)Temperature affects all enzymes simultaneously in a metabolic system. The enzyme concentration in a biochemical system can be considered as invariant under fast and small temperature change. Therefore, the total sensitivity ... -
Simulations of "tunnelling of the 3rd kind"
(Journal article; Peer reviewed, 2017-07)We consider the phenomenon of “tunnelling of the 3rd kind” [1], whereby a magnetic field may traverse a classically impenetrable barrier by pair creation of unimpeded quantum fermions. These propagate through the barrier ... -
Simulations of Cold Electroweak Baryogenesis: finding the optimal quench time
(Journal article; Peer reviewed, 2017-07)We revisit the numerical computation of the baryon asymmetry from Cold Electroweak Baryogenesis given the physical Higgs mass. We investigate the dependence of the asymmetry on the speed at which electroweak symmetry ... -
