The problem of weakly correlated electrons on a square lattice is formulated in terms of one-loop renormalization group. Starting from the action for the entire Brillouin zone (and not with a low-energy effective action) we reduce successively the cutoff Λ about the Fermi surface and follow the renormalization of the coupling U as a function of three energy-momenta. We calculate the intrinsic s...

Female orang-utans in a Sumatran swamp forest live in large, but stable, and widely overlapping home ranges. They preferentially associate with some of their female neighbours, possibly relatives, to form socially distinct clusters that also experience reproductive synchrony. Sexually mature males range more widely than females, but among them the dominant adult male has a relatively more limit...

Correction for 'High throughput first-principles calculations of bixbyite oxides for TCO applications' by Nasrin Sarmadian et al., Phys. Chem. Chem. Phys., 2014, 16, 17724-17733.

Low-pressure cold spraying is a newly developed technology with high application potential. The aim of this study was to investigate potential application of this technique for producing a new type of transparent conductive oxide films target. Cold spraying technique allows the manufacture of target directly on the backing plate; therefore the proposed sputtering target has a form of Sn+In2O3 c...

It is shown that the fusion of strings is a source of particle production in nucleus–nucleus collisions outside the kinematical limits of nucleon–nucleon collisions. The spectrum of different particles is compared with the high energy data on p–A collisions obtaining a reasonable agreement. Results for A–B collisions at √ s = 19.4 AGeV and √ s = 200 AGeV are given. It is shown that the fusion o...

T he explosive growth of the college athletics " business " has dramatically altered these amateur games over the past decade. The multimillion dollar university sports enterprises often dwarf academic departments in terms of resources. Athletic departments are commanding more and more attention of college presidents and governing boards, and rightfully so! While many of the perennial top compe...

Five endopectate lyases from the phytopathogenic bacterium Erwinia chrysanthemi, PelA, PelB, PelD, PelI, and PelL, were analyzed with respect to their modes of action on polymeric and oligomeric substrates (degree of polymerization, 2 to 8). On polygalacturonate, PelB showed higher reaction rates than PelD, PelI, and PelA, whereas the reaction rates for PelL were extremely low. The product prog...

OBJECTIVE Narcolepsy with cataplexy (NC) and narcolepsy without cataplexy (NwoC) are lifelong neurological disorders characterized primarily by excessive daytime sleepiness. Emotional events such as laughter are a trigger of cataplexy in NC. METHODS We compared the volumes of key limbic structures, the amygdala and hippocampus, in 53 NC, 23 NwoC and 37 control subjects. MRI volumetry was perf...
