The life history of Enochrus quadripunctatus Herbst was studied in the laboratory. The duration of each developmental stage, larval behavior, and preimaginal mortality rate were determined. It takes the insect a total of 43 days from hatching to reach the adult stage, with a high mortality rate in the first stadium. The mortality rate decreases as the beetle passes through the immature sta...

Temporomandibular joint (TMJ) involvement is common but usually delayed in patients with juvenile idiopathic arthritis (JIA). We describe the case of a JIA patient with bilateral TMJ involvement, mandibular retrognathia, bone erosion, and severely restricted mouth opening. The use of cone beam computed tomography and a 3D diagnostic protocol in young patients with JIA provides reliable, accurat...

Abstract. This is the the second part of a series of two papers, which investigate spectral properties of Dirac operators with singular potentials. We will provide a spectral analysis of a relativistic oneelectron atom in interaction with the second quantized radiation field and thus extend the work of Bach, Fröhlich, and Sigal [5] and Hasler, Herbst, and Huber [19] to such systems. In particul...

The ground-state energy of heavy one-electron ions in an inhomogeneous locally bounded magnetic field is estimated by the variational principle. The ions are described by means of the pseudorelativistic Herbst/Chandrasekhar operator. Two classes of magnetic fields are considered which model a field-free region around the central charge. It is shown that for a certain size of this region the gro...

The following three species of Helophoridae are newly recorded for New Brunswick, Canada: Helophorus (Kyphohelophorus) turberculatus Gyllenhal, Helophorus (Rhopaleloporus) oblongus LeConte, Helophorus (Rhopaleloporus) marginicollis Smetana. Hydrochus subcupreus Randall, family Hydrochidae, and the following 15 species of Hydrophilidae are newly reported for the province: Berosus fraternus LeCon...

Seit mehr als 40 Jahren etabliert sich das Fach Informatik in Nordrhein-Westfalen, doch die strukturellen Rahmenbedingungen machen Informatik für viele Schülerinnen und Schüler wenig attraktiv. Die Erwartungen und Erfahrungen im Hinblick auf Informatikunterricht schrecken scheinbar vor einer Wahl von Informatik ab. Den schon länger vermuteten Zusammenhängen möchte die Studie nachgehen, denn emp...

Little or no genetic divergence is detected using mitochondrial 16S rDNA sequence comparisons across the entire geographic range of the scorpion Euscorpius italicus (Herbst 1800) from Switzerland, Italy, Slovenia, Greece and Turkey. This is consistent with known absence of patterns of allozymes and morphological variation. Euscorpius italicus is found almost exclusively in human habitations. It...

We prove some new concentration inequalities for self-bounding functions using the entropy method. As an application, we recover Talagrand’s convex distance inequality. The new Bernstein-like inequalities for self-bounding functions are derived thanks to a careful analysis of the so-called Herbst argument. The latter involves comparison results between solutions of differential inequalities tha...

We obtain non asymptotic bounds for the Monte Carlo algorithm associated to the Euler discretization of some diffusion processes. The key tool is the Gaussian concentration satisfied by the density of the discretization scheme. This Gaussian concentration is derived from a Gaussian upper bound of the density of the scheme and a modification of the so-called “Herbst argument” used to prove Logar...
