The Stark effect in the charge-dyon system

The linear Stark effect in the MIC-Kepler problem describing the interaction of charged particle with Dirac's dyon is considered. It is shown that constant homogeneous electric field completely removes the degeneracy of the energy levels on azimuth quantum numberComment: 6 page

Subcircular perforations of the hard palate of the individual from Lchashen site (Armenia)

This paper identifies the presence of palate cleft in the individual from Middle Bronze Age and Late Bronze Age in the Armenia. The remains of skeleton from Lchashen site (burial 221/2), comprise the skull and post-cranial skeleton of a female 30-39 years. Macroscopic physical examination revealed that individual suffered from inflammation. The study reveals that inflammation possibly caused by because of sinusitis or inhaling polluted air for a long duration. In addition, we have seen skeletal evidence for pulmonary disease: tuberculosis. The female from Lchashen led a physically strenuous lifestyle

Facial clefting in a XVII - XVI centuries BC from Lchashen site, Armenia

This paper identifies the presence of facial clefting in archaeological population from Middle Bronze Age and Late Bronze Age in Armenia. The remains of skeleton from Lchashen site (burial 221/2), comprise the skull and post-cranial skeleton of a female 30-39 years. Macroscopic physical examination revealed that individual suffered from inflammation. Considering the ethnographic aspects, the study reveals that inflammation possibly caused by because of sinusitis or inhaling polluted air for a long duration. In addition, we have seen skeletal evidence for pulmonary disease: tuberculosis. The severe dental wear is a direct result of the food processing techniques used by prehistoric Armenia. We have seen evidence of interpersonal violence. All of these factors suggest that the female from Lchashen led a physically strenuous lifestyle. Before us is the individual with signs of intensive exercise stresses

The genetic history of the Southern Arc: a bridge between West Asia and Europe

By sequencing 727 ancient individuals from the Southern Arc (Anatolia and its neighbors in Southeastern Europe and West Asia) over 10,000 years, we contextualize its Chalcolithic period and Bronze Age (about 5000 to 1000 BCE), when extensive gene flow entangled it with the Eurasian steppe. Two streams of migration transmitted Caucasus and Anatolian/Levantine ancestry northward, and the Yamnaya pastoralists, formed on the steppe, then spread southward into the Balkans and across the Caucasus into Armenia, where they left numerous patrilineal descendants. Anatolia was transformed by intra–West Asian gene flow, with negligible impact of the later Yamnaya migrations. This contrasts with all other regions where Indo-European languages were spoken, suggesting that the homeland of the Indo-Anatolian language family was in West Asia, with only secondary dispersals of non-Anatolian Indo-Europeans from the steppe

Thin-film solar cells on perlite glass-ceramic substrates

For the first time, thin-film CIGS solar cells have been fabricated by co-evaporation on specially developed non-conducting perlite (an aluminum potassium sodium silicate natural mineral of volcanic origin) glass-ceramic substrates to develop a fully integrated photovoltaic and building element. Such glass-ceramic material can meet the physical requirements to solar cells substrates as well as the cost goals. The preliminary data presented show that CIGS solar cells deposited on ceramic substrates can exhibit efficiency higher than 10%

PITZ Experience on the Experimental Optimization of the RF Photo Injector for the European XFEL

The Photo Injector Test facility at DESY, Zeuthen site PITZ , develops high brightness electron sources for modern free electron lasers. A continuous experimental optimization of the L band photo injector for such FEL facilities like FLASH and the European XFEL has been performed for a wide range of electron bunch charges from 20 pC to 2 nC yielding very small emittance values for all charge levels. Experience and results of the experimental optimization will be presented in comparison with beam dynamics simulations. The influence of various parameters onto the photo injector performance will be discusse

A genetic probe into the ancient and medieval history of Southern Europe and West Asia

Literary and archaeological sources have preserved a rich history of Southern Europe and West Asia since the Bronze Age that can be complemented by genetics. Mycenaean period elites in Greece did not differ from the general population and included both people with some steppe ancestry and others, like the Griffin Warrior, without it. Similarly, people in the central area of the Urartian Kingdom around Lake Van lacked the steppe ancestry characteristic of the kingdom’s northern provinces. Anatolia exhibited extraordinary continuity down to the Roman and Byzantine periods, with its people serving as the demographic core of much of the Roman Empire, including the city of Rome itself. During medieval times, migrations associated with Slavic and Turkic speakers profoundly affected the region
