It has been found that hole doping with Li decreases the\nsuperconducting transition temperature Tc, but at a slower rate than electron\ndoping with C or Al. Tc of MgB2 crystals with simultaneously substituted Li for\nMg and C for B decreases more than in the case where C is substituted alone.\nThis means that holes introduced by Li cannot counterbalance the effect of\ndecrease of Tc caused by introduction of electrons coming from C. The possible\nreason of it can be that holes coming from Li occupy the pi band while\nelectrons coming from C fill the sigma band. The temperature dependences of the\nupper critical field Hc2 for Al and Li substituted crystals with the same Tc\nshow a similar dHc2/dT slope at Tc and a similar Hc2(T) behavior, despite of\nmuch different substitution level. This indicates that the mechanism\ncontrolling Hc2 and Tc is similar in both hole and electron doped crystals.\nElectrical transport measurements show an increase of resistivity both in Li\nsubstituted crystals and in Li and C co-substituted crystals. This indicates\nenhanced scattering due to defects introduced by substitutions including\ndistortion of the lattice. The observed behavior can be explained as a result\nof two effects, influencing both Tc and Hc2. The first one is doping related to\nthe changes in the carrier concentration, which may lead to the decrease or to\nthe increase of Tc. The second one is related to the introduction of new\nscattering centers leading to the modification of the interband and/or\nintraband scattering and therefore, to changes in the superconducting gaps and\nto the reduction of Tc.\n', '[{\"version\":\"v1\",\"created\":\"Thu, 26 Apr 2007 12:30:39 GMT\"}]', '2008-10-16', '[[\"Karpinski\",\"J.\",\"\"],[\"Zhigadlo\",\"N.\",\"\"],[\"Katrych\",\"S.\",\"\"],[\"Batlogg\",\"B.\",\"\"],[\"Tortello\",\"M.\",\"\"],[\"Rogacki\",\"K.\",\"\"],[\"Puzniak\",\"R.\",\"\"]]'),

Drifting subpulses are in general found at both\nfrequencies, although the chance of detecting drifting subpulses is possibly\nslightly higher at 92 cm.

In the non-dissipative case, we find Kelvin-Helmholtz\ninstability for flow velocities exceeding a critical speed that depends on the\nAlfv{\\\'e}n speed and on the ratio of the internal and external densities.\nInclusion of a friction term proportional to the relative transverse velocity\nleads to a friction-driven instability connected with backward (or negative\nenergy) waves. We discuss the physical nature of this instability. In the case\nof a stratified external medium, the Kelvin-Helmholtz instability and the\nfriction-driven instability can set in for flow speeds significantly lower than\nthe Alfv{\\\'e}n speed. Dissipative effects can excite flow-driven instability\nbelow the thresholds for the Kelvin-Helmholtz and the undulatory (Parker-type)\ninstabilities.

In the limit that the initial\nred-shift tends to infinity, at fixed particle density, the evolution in fact\ndiverges from that in the fluid limit (described by the Zeldovich\napproximation).

Indeed, observational evidence for\ndownsizing shows the average age of the stars in a galaxy to decrease with\ndecreasing mass and metallicity. However, we conclude both from observational\nand theoretical viewpoints that metallicity is not an arrow of time.\nConsequently the most metal poor galaxies of our local universe are not\nnecessarely young. Current observations suggest that an old stellar population\nis present in all metal-poor galaxies, although a couple of cases, e.g. IZw18,\nremain under debate. Further observations with more sentitive equipement should\nsettle this question in the coming years.\n', '[{\"version\":\"v1\",\"created\":\"Sat, 28 Apr 2007 15:36:36 GMT\"}]', '2015-05-13', '[[\"Kunth\",\"Daniel\",\"\",\"Institut Astrophysique de Paris, France; kunth at\\n  iap.fr\"],[\"Ostlin\",\"Goran\",\"\",\"Stockholm Observatory, Sweden; ostlin at\\n  astro.su.se\"]]');
