The technique of particle correlation measures directly electron modulations that result from naturally occurring and actively stimulated wave-particle interactions in space plasmas. In the past this technique has been used for studies of beam-plasma interactions, caused by both natural auroral electron beams via sounding rockets and by artificially generated electron beams on Space Shuttle mis...

We describe numerical calculations which examine the PhillipsSarnak conjecture concerning the disappearance of cusp forms on a noncompact finite volume Riemann surface S under deformation of the surface. Our calculations indicate that if the Teichmüller space of S is not trivial, then each cusp form has a set of deformations under which either the cusp form remains a cusp form or else it dissol...

We study the non-linear structure formation in cosmology accounting for quantum nature of dark matter (DM) particles initial conditions at decoupling, as well relaxation and stability DM halos. Differently from cosmological N-body simulations, we use a thermodynamic approach collisionless systems self-gravitating fermions General Relativity, which halos reach steady state by maximizing coarse-g...

Data collected by the Fast Imaging Plasma Spectrometer (FIPS) aboard MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft showed singly charged Na+-group ions at energies of between 1 13 keV in Mercury's northern planetary cusp. Most these are likely formed either photoionization or charge exchange exospheric Na atoms, with initial approximately eV less. FIPS obs...

Abstract During the Twin Rockets to Investigate Cusp Electrodynamics (TRICE‐2) High‐Flyer rocket's passage through cusp high frequency (HF) radio wave receiver observed three intervals of banded upper‐hybrid (UH) waves. The bands begin at UH ( 1.2–1.3 MHz), descending as low 1.1 MHz, with amplitudes hundreds mV/m. spacing are 4.5–6 kHz and number ranges from 3 10. Simultaneously, very (VLF) low...

We present flux-ratio curves of the fold and cusp (i.e. close multiple) images of six JVAS/CLASS gravitational lens systems. The data were obtained over a period of 8.5 months in 2001 with the Multi-Element Radio-Linked Interferometer Network (MERLIN) at 5–GHz with 50 mas resolution, as part of a MERLIN Key-Project. Even though the time delays between the fold and cusp images are small (1 d) co...

On 16 March 2002, Cluster moved from nightside to dayside, across the high-altitude northern cusp during an extended period of relatively steady positive IMF BY and BZ. Combined Cluster and SuperDARN data imply the existence of two reconnection sites: in the highlatitude northern hemisphere dusk and southern hemisphere dawn sectors. Within the cusp, Cluster encounters 3 distinct plasma regions....

Aim: To investigate the number of molar cusps of the Southern Chinese and compare these with studies in different populations. Materials and Methods: The number of molar cusps of study casts of an unselected sample from a 12 year old Hong Kong Oral Health Survey of 12 year old children (n=459; 295 boys and 164 girls) were studied. Results: For upper first molars, 5-cusp molars were the most pre...

There are few informations about the influence of cusp inclination on the fracture strength of implant-supported crowns. The study aimed to evaluate the influence of cusp inclination and retention type on fracture load in implant-supported metal-ceramic single crowns. Sixty crowns were made, classified as cemented and screw-retained with screw access hole (SAH) sealed or not. Standard (33°) and...
