Leptogenys is the most diverse ponerine ant genus in the world; it is widespread throughout tropical and subtropical regions and there are over 200 extant species described. Most species have ergatoid queens, and many have falcate, bowed mandibles and are specialists on isopod prey. Here, the Malagasy Leptogenys are revised with 60 species recognized, of which 40 are newly described, 18 redescr...

Three patients with Emery Dreifuss muscular dystrophy are reported. Emery Dreifuss muscular dystrophy is an X linked muscular dystrophy, in which locomotor involvement is characteristically mild and slowly progressive. The effect on the heart becomes apparent in the teenage years and is characterised by cardiac conduction defects and infiltration of the myocardium by fibrous and adipose tissue....

We study the one-dimensional deformed t−t−J model in terms of the continuum field theories. We found that at low doping concentration and far away from the phase separation regime, there are two phases: the Luttinger liquid and the Luther-Emery liquid, depending on t/t < (t′/t)c or t /t > (t′/t)c, where (t′/t)c > 0. Moreover, the singlet superconducting correlations are dominant in the Luther-E...

Morocco hosts a high diversity of animal and plant species, including diverse ant fauna. Here, we report collection records four species not previously known from Morocco: Goniomma kugleri Espadaler, 1986, Strumigenys rogeri Emery, 1890, Temnothorax longipilosus (Santschi, 1912) Proceratium numidicum Santschi, 1912. G. is mentioned for the first time continental Africa. This raises number to 24...

A generalised integer S Ising spin glass model is analysed using the replica formalism. The bilinear couplings are assumed to have a Gaussian distribution with ferromagnetic mean < Jij >= J0. Incorporation of a quadrupolar interaction term and a chemical potential leads to a richer phase diagram with transitions of first and second order. The first order transition may be interpreted as a phase...

A recent catalogue of the rich ant fauna of Morocco included 214 species, with later studies adding an additional 12 species. Following recent fieldwork in the north of Morocco, we report five new records for the country (Plagiolepis pygmaea Latreille, 1798, Ponera testacea Emery, 1895, Strumigenys tenuipilis Emery, 1915, Temnothorax pardoi Tinaut, 1987, and Tetramorium parvioculum Guillem & Be...
