چکیده
We report on selected activities that took place at the 2013 Spring Meeting of the German Physical Society (DPG) in Regensburg, including the focused sessions and symposium on “Frontiers of Electronic Structure Theory”, the Volker Heine Young Investigator award to Michele Ceriotti, the activities of ETSF (the European Theoretical Spectroscopic Facility), the plenary talk of Olle Eriksson, and anything else that caught the fancy of the group members. 1 “Frontiers of Electronic Structure” Sessions and Symposium Together with Matthias Scheffler (FHI Berlin) and Ralf Drautz (ICAMS Bochum), we organized seven focused sessions on “Frontiers of Electronic Structure Theory” (supported by the Surface Science division, and in addition by the Semiconductor and Low Temperature divisions) together with a final Friday morning Symposium on “Frontiers of Electronic Structure Theory: Discovery of Novel Functional Materials” (supported, in addition, by the divisions of Thin Films, Magnetism, and Metals and Materials). This activity encompassed 10 invited talks, 64 contributed talks, and 5 invited talks from the speakers that had been selected by Psi-k for the Volker Heine Young Investigator Award. A chronological summary of the 10 invited talks and of the Volker Heine session is presented here first. Jörg Neugebauer (Max-Planck-Institut für Eisenforschung, Düsseldorf): Fully abinitio determination of free energies: Basis for high-throughput approaches in materials design. Jörg reported their results on calculating partition functions and heat capacities fully from firstprinciples, using a combination of LDA or GGA calculations to determine phonon frequencies and quasi-harmonic contributions to the vibrational free energies, plus electronic, magnetic and anharmonic contributions, and applying it to metals, with of course a focus on iron and iron alloys (see Psi-k Highlight 105 for an introduction on the topic). Magnetic excitations were included calculating a spin Hamiltonian based on the Heisenberg model, with 30-or-more neighbors, and shown to reproduce correctly experimental magnon dispersions. Three techniques were used to solve the problem Classical Monte Carlo (that was

Hybridity of Scientific Discourses: an Intertextual Perspective and Implications for ESP Pedagogy
In light of a large number of admirable attempts which look at scientific discourse from social, dialogic and interpersonal points of view, the propositions which consider scientific discourse as an interactive endeavor are now well-established. By the force of our social constructivist gyrations, we have developed glimpses of a social, cultural and historical dimension in which the discourse o...
متن کاملPrevalence of underweight in Iranian children: a systematic review and meta-analysis
Background: Children's health, preserving and promoting it is a health priority of any society. Malnutrition affects all age groups, but malnutrition in children is one of the most common nutritional problems that can delay body growth, shortened height, frequent infections, mental retardation, the prevalence of mental disorders, lack of academic achievement and reduced efficacy. Because of the...
متن کاملThe Zeitgeist of Challenging the Evidence. A Perspective on the International Consensus Meeting on Periprosthetic Joint Infection
Background: The economic burden of the treatment of periprosthetic joint infection (PJI) is high and the treatment of PJI has a high degree of international controversy. Several papers have declared the International Consensus Meeting on Periprosthetic Joint Infection (ICMPJI) to be the "flawless pledge of international academics" to overcome the challenges of musculoskeletal infections. The p...
متن کاملNEUROGENIC HYPERTENSION: REPORT OF FIVE CASES TO HIGHLIGHT THE CONTROVERSY
The entity of "neurogenic hypertension" is defined as arterial hypertension caused explicitly by derangement of the intricate network of the central nervous system. Among 193 cases of cranial rhizopathies operated on between 1984 and 1995 at this center, 5 cases of established arterial hypertension with concomitant rhizopathies also underwent ventrolateral medullary decompression. The elev...
متن کاملReport of the second conference on diabetes and Ramadan, Iran, Mashhad, 2017
The phrase " va man kan marizan " on the fasting of the holy month of Ramadan in the verse of 185 of the Qur'anic Surah, followed by the phrase "Yaridullah Bekem Alisar va Yerido bekom alosr", is undoubtedly a major task of medical scientific assemblies. To conduct comprehensive and evidence-based studies, firstly, should determine the course of fasting in patients, and, second, patients who ma...
