Study of hadronic event shape in flavour tagged events in e+e- annihilation at
Salvatore Mele, PMC Physics A 2008, 2:6 (8 December 2008)
Results are presented from a study of the structure of hadronic events in high-energy e+e- interactions detected by the L3 detector at LEP. Various event shape distributions and their moments are measured at several energy points at and above the Z-boson mass. A good description of the data is provided by the models. -

Plasma focus based repetitive source of fusion neutrons and hard x-rays
V Raspa, F Di Lorenzo, P Knoblauch, A Lazarte, A Tartaglione, A Clausse, C Moreno PMC Physics A 2008, 2:5 (29 October 2008)
A plasma focus device that operates up to 0.2 Hz for several minutes is used as a source of hard x-rays and fast neutrons, for the detection of hydrogenated substances, different concentrations of water, submillimetric defects in metal, and producing clear images of metallic objects through thick iron walls. -

Hadron multiplicity in e+e- events induced by top quark pairs at the ILC energy
Alexandre V Kisselev, Vladimir A Petrov PMC Physics A 2008, 2:3 (4 April 2008)
The average charged hadron multiplicity in the e+e− events with the primary t¯t-pair at the collision energy 500 GeV, as well as the average multiplicity of charged hadrons from the top quark are calculated in QCD to be 86.7 ± 1.11 and 41.0 ± 0.54, respectively. -

Effects of supersymmetric threshold corrections on high-scale flavour textures
Altan Çakir, Levent Solmaz PMC Physics A 2008, 2:2 (7 March 2008)
Integration of superpartners out of the spectrum induces potentially large contributions to Yukawa couplings. Supersymmetric threshold corrections therefore influence the CKM matrix prediction in a non-trivial way. We study the effects of threshold corrections on high-scale flavor structures specified at the gauge coupling unification scale in supersymmetry. -

Supernova Ia observations in the Lemaître-Tolman model
Krzysztof Bolejko PMC Physics A 2008, 2:1 (12 February 2008)
This paper investigates whether models including realistic inhomogeneous matter distribution but without the cosmological constant can produce dimming of high-redshift supernovae consistent with acceleration of the Universe. It is found that, although the model mimics observations at small scales, the cosmological constant must be invoked to account for dimming over larger scales.
