description: The work of the Site Management Project in Didyma based on a concept, which was developed 2012 and 2013 and pursues two main objectives. First of all it implies the construction of a new guided tour of the ancient ruins of Didyma, which includes the archaeological site of the sacred way, inaccessible and not visible before, and on the other hand the numerous architectural members, deposited systematically in the area of the Apollontemple during its excavation (1906–1913) for purposes of study (ancient architecture). Furthermore on the basis of injury analysis and damage mapping a scientific concept was developed for the restoration of the collapsed or in danger of collapsing sections of the enclosing wall of the temple area.

description: Aspendos is one of the most important urban centers of Roman Asia Minor, but was neglected in archaeological research for longtime. Well known are the impressive and virtuous drawings of major Roman monuments by George Niemann from the late 19th century. In 2008 a multi-annual survey project was started by Veli Köse (Ankara Hacettepe Üniversitesi) in Aspendos, with the aim to create a uniform level of documentation and a detailed knowledge base for an excavation project carried out for the first time in Aspendos. The first excavation campaign was started in 2012 in cooperation with the Museum of Antalya. The Istanbul Department of the German Archaeological Institute is involved in this research project of Veli Köse in cooperation and carried out primarily architectural surveys of the major Roman monuments, but was also involved in the excavation documentation.

description: The research on the Roman camp of Charvátská Nová Ves in Moravia took place within the framework of a cooperative project on the study of military activities during the period of the Marcomannic wars (bellum Germanicum et Sarmaticum) north of the Pannonian Danube frontier in the reign of Emperor Marcus Aurelius (166–180 AD). With archaeological and scientific methods, temporary camps from the Roman campaigns were examined within the context of the Germanic settlements. The fieldwork in 2013–2014 focused on the camp in Charvátská Nová Ves, which was discovered in the early 1990s. With an inner surface of just over 40 hectares, it is the largest temporary camp west of the Little Carpathians and provided space to a field army of more than 10,000 legionaries.

description: Archaeological investigations on the site of Tharsis (Alosno, province Huelva) and its surroundings were carried out in cooperation with colleagues of the University of Huelva between 2007 and 2010. The main objective consisted in the analysis of the relation between a major mining centre as is Tharsis and its surroundings with its extraordinarily huge deposits of copper and silver mainly, which were explored from the beginning of the Metal Ages (Copper Age) onwards until nowadays. The project is of major interest as the search of these metals is a persistent element especially in the Iron Age Hispaniae and achieves a new flourishing period in Roman times. With a focus on this time span, three places in the nearer surroundings were studied: Cerro de la Divisa (8th/7th c. BC), Castro Cerquillo (5th/4th cent. BC) and Lagunazo (roman time). Other places in the farther surroundings as Tejada la Vieja, Niebla and Ayamonte have also to be considered, as slags are found in all of them. In one way or another, the nearer and the farer surroundings must have participated in Tharsis‘ richness. The inclusion of Ayamonte establishes a link to another project also run by DAI Madrid (D. Marzoli).

description: The characterization of interstellar chemical inventories provides valuable insight into the chemical and physical processes in astrophysical sources. The discovery of new interstellar molecules becomes increasingly difficult as the number of viable species grows combinatorially, even when considering only the most thermodynamically stable. In this work, we present a novel approach for understanding and modeling interstellar chemical inventories by combining methodologies from cheminformatics and machine learning. Using multidimensional vector representations of molecules obtained through unsupervised machine learning, we show that identification of candidates for astrochemical study can be achieved through quantitative measures of chemical similarity in this vector space, highlighting molecules that are most similar to those already known in the interstellar medium. Furthermore, we show that simple, supervised learning regressors are capable of reproducing the abundances of entire chemical inventories, and predict the abundance of not yet seen molecules. As a proof-of-concept, we have developed and applied this discovery pipeline to the chemical inventory of a well-known dark molecular cloud, the Taurus Molecular Cloud 1 (TMC-1); one of the most chemically rich regions of space known to date. In this paper, we discuss the implications and new insights machine learning explorations of chemical space can provide in astrochemistry.

description: As a part of the TOPOI Excellence Cluster in Berlin the immediate and wider hinterland of the late antique fortified palace of Felix Romuliana associated with the emperor Galerius (283–311 AD) was studied. Despite a long research tradition at the palace, there has been little study of its hinterland. In investigating the settlement patterns surrounding Felix Romuliana from prehistoric to mediaeval times important insights into the diachronic development of this micro-region were provided and led also to a new understanding of the historic and topographic framework of the role of the palace.

description: Quasi-periodic signals have yielded important constraints on the masses of black holes in galactic X-ray binaries, and here we extend this to active galactic nuclei (AGNs). We employ a wavelet technique to analyze 19 observations of 10 AGNs obtained with the XMM-Newton EPIC pn camera. We report the detection of a candidate 3.3 ks quasi period in 3C 273. If this period represents an orbital timescale originating near a last stable orbit of 3Rs, it implies a central black hole mass of 7.3x10^6 Msun. For a maximally rotating black hole with a last stable orbit of 0.6Rs, a central black hole mass of 8.1x10^7 Msun is implied. Both of these estimates are substantially lower than previous reverberation-mapping results, which place the central black hole mass of 3C 273 at about 2.35 x10^8 Msun. Assuming that this reverberation mass is correct, the X-ray quasi period would be caused by a higher order oscillatory mode of the accretion disk.

Situated on a slight hill along a river bend, Tartas 1 and the opposite burial ground of Sopka 2 form the centre of a burial tradition lasting for more than 4000 years. Tartas 1 is excavated in a joint Russian-German project of the Eurasia department and the Institute of Archaeology and Ethnography of the Siberian Branch RAS since 2004. Meanwhile more than 650 burials have been excavated, together with more than thousand pits, which belong to ritual or domestic structures. The site is a focus of multidisciplinary investigation including ancient DNA studies, radiocarbon and bioarchaeological analytics.

description: We study the $3~μ$m scattering feature of water ice detected in the outer disk of HD 142527 by performing radiative transfer simulations. We show that an ice mass abundance at the outer disk surface of HD 142527 is much lower than estimated in a previous study. It is even lower than inferred from far-infrared ice observations, implying ice disruption at the disk surface. Next, we demonstrate that a polarization fraction of disk-scattered light varies across the ice-band wavelengths depending on ice grain properties; hence, polarimetric spectra would be another tool for characterizing water-ice properties. Finally, we argue that the observed reddish disk-scattered light is due to grains with a few microns in size. To explain the presence of such grains at the disk surface, we need a mechanism that can efficiently oppose dust settling. If we assume turbulent mixing, our estimate requires $α\gtrsim2\times10^{-3}$, where $α$ is a non-dimensional parameter describing the vertical diffusion coefficient of grains. Future observations probing gas kinematics would be helpful to elucidate vertical grain dynamics in the outer disk of HD 142527.

description: Standard thermodynamic treatments of quantum field theory in the presence of black-hole backgrounds reproduce the black hole entropy by usually specializing to the leading order of the heat-kernel or the high-temperature expansion. By contrast, this work develops a hybrid framework centered on geometric spectral asymptotics whereby these assumptions are shown to be unwarranted insofar as black hole thermodynamics is concerned. The approach--consisting of the concurrent use of near-horizon and heat-kernel asymptotic expansions--leads to a proof of the holographic scaling of the entropy as a universal feature driven by conformal quantum mechanics.

description: We investigate the Josephson current through a suspended carbon nanotube double quantum dot which, at sufficiently low temperatures, is characterized by the ground state of the electronic subsystem. Depending on parameters like a magnetic field or the inter-dot coupling, the ground state can either be a current-carrying singlet or doublet, or a blockaded triplet state. Since the electron-vibration interaction has been demonstrated to be electrostatically tuneable, we study in particular its effect on the current-phase relation. We show that the coupling to the vibration mode can lift the current-suppressing triplet blockade by inducing a quantum phase transition to a ground state of a different total spin. Our key finding is the development of a triple point in the Josephson current parameterized by the resonator coupling and the Josephson phase. The quantum phase transitions around the triple point are directly accessible through the critical current and resilient to moderately finite temperatures. The proposed setup makes the mechanical degree of freedom part of a superconducting hybrid device which is interesting for ultra-sensitive displacement detectors.

description: We use the Millennium Simulation (MS) to study the statistics of LCDM halo concentrations at z = 0. Our results confirm that the average halo concentration declines monotonically with mass; a power-law fits well the concentration-mass relation for over 3 decades in mass, up to the most massive objects to form in a LCDM universe (~ 10^15 h^-1 Msol). This is in clear disagreement with the predictions of the model proposed by Bullock et al. for these rare objects, and agrees better with the original predictions of Navarro, Frenk, & White. The large volume surveyed, together with the unprecedented numerical resolution of the MS, allow us to estimate with confidence the distribution of concentrations and, consequently, the abundance of systems with unusual properties. About one in a hundred cluster haloes (M200 >~ 3x10^14 h^-1 Msol) have concentrations exceeding c200 = 7.5, a result that may be used to interpret the likelihood of unusually strong massive gravitational lenses, such as Abell 1689, in the LCDM cosmogony. A similar fraction (1 in 100) of galaxy-sized haloes (M200 ~ 10^12 h^-1 Msol) have c200 < 4.5, an important constraint on models that attempt to reconcile the rotation curves of low surface-brightness galaxies by appealing to haloes of unexpectedly low concentration. We find that halo concentrations are independent of spin once haloes manifestly out of equilibrium are removed from the sample. Compared to their relaxed brethren, the concentrations of out-of-equilibrium haloes tend to be lower and to have more scatter, while their spins tend to be higher... (continue)

As networks deviate from the regular structure, $Δ_3$ follows random matrix prediction of linear behavior, in semi-logarithmic scale with the slope of $1/π^2$, for the longer scale.
Geology, geochemistry, and geochronology of the Westcoast Crystalline Complex and related rocks, Vancouver Island, British Columbia
Creators: name: Isachsen, Clark
Publisher: name: University of British Columbia
Year: 2010

description: The Westcoast Crystalline Complex occurs as a belt of complexly mixed plutonic rocks along the west coast of Vancouver Island. It is composed mainly of heterogeneous amphibolitic country rock (Westcoast Amphibolite), granitoids of trondhjemitic to gabbroic composition (Westcoast Diorite), and variable mixtures of these two components (Westcoast Migmatite). Various lines of evidence suggest that these rocks were generated in a magmatic arc setting and intruded the crust in Jurassic time. Major and trace element chemistry of the Westcoast Crystalline Complex shows a subalkaline tholeiitic to calc-alkaline trend compatible with petrogenesis in a magmatic arc. U-Pb isotopic dates of zircon separates are consistently concordant between 176 and 189 Ma and show no appreciable evidence for an older crustal component. Initial Sr ratios obtained for the Westcoast Crystalline Complex are between 0.70329 and 0.70360, compatible with a depleted mantle source region. The concave cooling curves derived for Westcoast Diorites are not consistent with in situ crustal magmagenesis but, instead, indicate that these rocks were intruded into relatively cool country rock. Based on age and chemistry, the Westcoast Crystalline Complex can be interpreted as the deeper crustal equivalent of the more differentiated Island Intrusions and Bonanza Volcanics. Taken together, these rocks provide a disrupted and perhaps incomplete cross-section of the Jurassic magmatic arc of Vancouver Island. Reconnaisance of the Wark/Colquitz Complex of southern Vancouver Island shows it to be essentially indistinguishable in petrography, chemistry and age from the Westcoast Crystalline Complex, and a similar history is inferred. A calc-alkaline chemistry and low initial Sr ratio were also determined for a Catface Intrusion dated at 41 Ma. This is again compatible with mantle-derived arc magmatism, but its proximity to the coeval trench is enigmatic.

description: We present a scanning tunneling microscopy (STM) technique to simultaneously measure the topography, the local tunnel barrier height (dI/dz) and the differential conductivity (dI/dV). We modulate the voltage and tip piezo with small sinusoidal signals that exceed the cut-off frequency of the STM electronics and feed the tunneling current into two lock-in amplifiers (LIAs). We derive and follow a set of criteria for the modulation frequencies to avoid any interference between the LIA measurements. To validate the technique, we measure Friedel oscillations and the subtle tunnel barrier difference between the hcp and fcc stacked regions of the Au(111) herringbone reconstruction. Finally, we show that our method is also applicable to open feedback loop measurements by performing grid I(V) spectroscopy.

description: We report on a search for the pair production of second generation scalar leptoquarks (LQ) in ppbar collisions at the center of mass energy sqrt(s)=1.96 TeV using a data set corresponding to an integrated luminosity of 1.0 fb-1 collected with the D0 experiment at the Fermilab Tevatron Collider. Topologies arising from the LQLQbar->muqnuq and LQLQbar->muqmuq decay modes are investigated. No excess of data over the standard model prediction is observed and upper limits on the leptoquark pair production cross section are derived at the 95% C.L. as a function of the leptoquark mass and the branching fraction beta for the decay LQ->muq. These are interpreted as lower limits on the leptoquark mass as a function of beta. For beta=1 (0.5), scalar second generation leptoquarks with masses up to 316 GeV (270 GeV) are excluded.

description: In a dense gas plasma a short laser pulse propagates in relativistic self-trapping mode, which enables effective conversion of laser energy to the accelerated electrons. This regime sustains effective loading which maximizes the total charge of the accelerating electrons, that provides a large amount of betatron radiation. The 3D particle-in-cell simulations demonstrate how such regime triggers X-ray generation with 0.1-1 MeV photon energies, low divergence, and high brightness. It is shown that a 135 TW laser can be used to produce $3\times 10^{10}$ photons of $>10$ keV energy and a 1.2 PW laser makes it possible generating about $10^{12}$ photons in the same energy range. The laser-to-gammas energy conversion efficiency is up to $10^{-4}$ for the high-energy photons, $\sim 100$ keV, while the conversion efficiency to the entire keV-range x-rays is estimated to be a few tenths of a percent.

description: It is well known that there should be a total cancellation of the IR divergences in unitary interacting field theories, such as QED and gravity. The cancellation should be at all orders between loop and tree level contributions to cross--sections. This is the crucial fact related to the unitarity of the evolution operator (S--matrix) of the underlying interacting field theory. In this note we show that such a cancellation does {\it not} happen in de Sitter space.

description: The continuous and discrete symmetries of the Kuramoto-Sivashinsky system restricted to a spatially periodic domain play a prominent role in shaping the invariant sets of its chaotic dynamics. The continuous spatial translation symmetry leads to relative equilibrium (traveling wave) and relative periodic orbit (modulated traveling wave) solutions. The discrete symmetries lead to existence of equilibrium and periodic orbit solutions, induce decomposition of state space into invariant subspaces, and enforce certain structurally stable heteroclinic connections between equilibria. We show, on the example of a particular small-cell Kuramoto-Sivashinsky system, how the geometry of its dynamical state space is organized by a rigid `cage' built by heteroclinic connections between equilibria, and demonstrate the preponderance of unstable relative periodic orbits and their likely role as the skeleton underpinning spatiotemporal turbulence in systems with continuous symmetries. We also offer novel visualizations of the high-dimensional Kuramoto-Sivashinsky state space flow through projections onto low-dimensional, PDE representation independent, dynamically invariant intrinsic coordinate frames, as well as in terms of the physical, symmetry invariant energy transfer rates.

description: We construct a model of direct gauge mediation of metastable SUSY breaking by simply deforming the Intriligator, Seiberg and Shih model in terms of a dual meson superpotential mass term. No extra matter field is introduced. The deformation explicitly breaks a U(1)_R symmetry and a pseudo moduli have a nonzero VEV at one-loop. Our metastable SUSY breaking vacuum turns out to be sufficiently long-lived. By gauging a subgroup of flavor symmetry, our model can directly couple to the standard model, which leads to nonvanishing gaugino mass generation. It is also shown that our model can evade the Landau pole problem. We show the parameters in the SUSY breaking sector are phenomenologically constrained.

description: The interdisciplinary project “Sizandro and Alcabrichel” began in 2006 to investigate and reconstruct the development of the landscape around the Copper Age fortified settlement of Zambujal (Torres Vedras, dist. Lisbon, Portugal) during the Holocene, in close cooperation with the American project “Excavations at the Burial of Bolores”. The most important results are the following: 1 – Archaeological surveys conducted along the two valleys of the Sizandro and Alcabrichel rivers show that there was, throughout later prehistory, a more dense population in the Sizandro area than in the Alcabrichel. The reason is most likely that there are more fertile soils on the Jurassic bedrock of the Sizandro, and poorer and sandier soils on the Cretaceous bedrock of the Alcabrichel valley. This result has been investigated in a soils science thesis. 2 – In 1987, a former sea bay was detected in the Sizandro valley. Additional borings along cross-sections of the valley were obtained to reconstruct its former shape. Because of the low water level of the Atlantic Ocean, due to the last Ice Age, the river excavated a deep gorge. 3 – During the process of global warming since the beginning of the Holocene, this gorge was filled by seawater to create a lagoon. 4 – Pollen analysis shows that in the second part of the 6th millennium BC (Early Neolithic), dramatic deforestation began, when the first farmers needed acres of land for their crops and pastures for their domesticated animals. This is supported by finds of Neolithic pottery at a beach and a shell midden, as well from a cave site. Another student thesis designed models of the landform configuration for the Holocene to find possible locations of Neolithic settlements. 5 – As a consequence of this deforestation, a process of sedimentation began that filled the Holocene lagoon. In the 3rd millennium BC, some of this lagoon still existed, but it was not very deep. Therefore, it is not likely there existed a harbour for seagoing ships of the Copper Age fortified settlement of Zambujal, as has been suggested. 6 – For the Chalcolithic period, a new reconstruction was painted according to new interdisciplinary studies. 7 – The excavations at the burial site of Bolores brought new insights into the health, diet, ancestry, social organization, and rituals of people living in the 3rd millennium BC. Analyses of the C, N and O isotopes of bones of sheep and goats from Zambujal demonstrated a significant difference in the diet of these animals between the early and later phases of the site, which is likely due to either an anthropogenic effect on the environment or climatic change.

description: Together with the Department of Historical Research of the „Ion Creangă“ State Pedagogical University of Chişinău (Moldova) and the National Museum of the Eastern Carpathians in Sfântu Gheorghe (Romania) the investigation of a late Roman/early Migration period settlement of the Sântana-de-Mureş- Culture (c. 230–430/450 AD) on the southern slope of the Kubolta Valley at Putinești, Raionul Florești, has been continued with geomagnetic prospection and aerial photogrammetry. The settlement was already known from field walking. The site is part of an area of settlement some 9,0 km long on the eastern edge of the Kubolta-valley, an area intensively colonised already in prehistoric times (Neolithic, Bronze Age).

description: The results of a five years’ cooperation between the Romano-Germanic Commission of the German Archaeological Institute and the Kosovar Archaeological Institute were presented to the public together with the German Embassy. The recording of burial finds from the necropolis of the Roman road station Videnis (Gllamnik/Glavnik) has been completed. Moreover, excavations in the Roman and early Byzantine town Ulpiana/Iustiniana Secunda were carried on. Sections of the defensive wall including towers have been uncovered and the inner development of the town has also been researched. Based on the existing cooperation agreement the German Mining Museum in Bochum conducted a further survey in the hinterland of Ulpiana.

description: After the discovery of the Higgs boson in 2012, particle physics has entered an exciting era. An important question is whether the Standard Model of particle physics correctly describes the scalar sector realized by nature, or whether it is part of a more extended model, featuring additional particle content. A prime way to test this is to probe models with extended scalar sectors at future collider facilities. We here discuss such models in the context of high-luminosity LHC, a possible proton-proton collider with 27 and 100 TeV center-of-mass energy, as well as future lepton colliders with various center-of-mass energies.

description: Several types of Wavefront Sensors (WFS) are nowadays available in the field of Adaptive Optics (AO). Generally speaking, their basic principle consists in measuring slopes or curvatures of Wavefront Errors (WFE) transmitted by a telescope, subsequently reconstructing WFEs digitally. Such process, however, does not seem to be well suited for evaluating co-phasing or piston errors of future large segmented telescopes in quasi real-time. This communication presents an original, recently proposed technique for direct WFE sensing. The principle of the device, which is named "Telescope-Interferometer" (TI), is based on the addition of a reference optical arm into the telescope pupil plane. Then incident WFEs are deduced from Point Spread Function (PSF) measurements at the telescope focal plane. Herein are described two different types of TIs, and their performance are discussed in terms of intrinsic measurement accuracy and spatial resolution. Various error sources are studied by means of numerical simulations, among which photon noise sounds the most critical. Those computations finally help to define the application range of the TI method in an AO regime, including main and auxiliary telescope diameters and magnitude of the guide star. Some practical examples of optical configurations are also described and commented.

title: Carbohydrate Feeding During Prolonged Cycling Exercise Improves Exercise Capacity but Does Not Alter Muscle Fuel Selection

description: The aim of this thesis was to determine the dose-response relationship of CHO feeding during exercise on muscle fuel selection and exercise capacity under conditions considered best nutritional practice. Study 1 demonstrated that after a 36 h CHO loading protocol and high CHO pre-exercise meal, trained male cyclists are capable of completing 180-min of submaximal exercise at lactate threshold (LT) and that fatigue during the subsequent exercise capacity test typically occurred within <10 minutes. However, important methodological considerations from this exercise protocol suggest that at least one full familiarisation of the complete exercise protocol should be included in subsequent studies. Study 2 and 3, utilising this protocol, reported that in conditions of high pre-exercise CHO availability (similar to Study 1), CHO feeding (comprising a mixture of solids, gels and fluids) during exercise improves cycling exercise capacity in a dose dependent manner such that 90 g·h-1 > 45 g·h-1 > 0 g·h-1 CHO. Such ergogenic effects were found to be independent of whole muscle glycogen, fibre-specific glycogen and intramuscular triglyceride (IMTG) sparing and in turn were suggested to be due to a combination of liver glycogen sparing, increased plasma glucose availability and greater maintenance of CHO oxidation. In addition, we report for the first time that 180-min of submaximal exercise reduces IMTG content in both the central and peripheral regions of type I and IIa fibres independent of CHO feeding and this was reflective of decreased LD number in both fibre types whereas reductions in LD size was exclusive to type I fibres. Study 4 aimed to subsequently quantify muscle glycogen utilisation in specific subcellular storage pools, as measured using transmission electron microscopy. However, due to the associated laboratory restrictions of the COVID-19 world pandemic, it was not possible to complete this analysis. Having assessed the effects of CHO feeding on fuel selection and exercise capacity in the laboratory setting, Study 5 used a case-study design to demonstrate the practical delivery of a periodised approach to CHO feeding for a professional World Tour cyclist during a Grand Tour. This approach was successful in supporting a winning performance and provides the first report in the literature to document the practical application of such a periodised approach in professional cycling. In summary, given that Grand Tours in professional road cycling can be won or lost with a matter of seconds, the findings within this thesis are of practical significance for road cyclists in that the chosen CHO strategy may improve the capacity to “hold a wheel” or “mount attacks” during the closing periods of race defining mountain stages.

description: The SALVE-research project (www.salve-research.org) aims at reconstructing the cultural landscape around Pompeii, i.e. the Sarno River plain, before the AD 79 eruption of Somma-Vesuvius. Special attention is drawn on paleo-topographical and paleo-environmental conditions as well as on socio-economic interrelationships particularly related to the ancient rural settlements (villae rusticae) and agricultural land use as well as to the ancient building materials. To gain deeper insight into Roman agricultural practice a geoarchaeological excavation was carried out in direct vicinity to a villa rustica to uncover a pre-AD 79 Roman agricultural soil and conduct multi-disciplinary analyses.

description: Working together with the Soprintendenza of Rome on the Campus Martius it has been possible to reconstruct the shape of the temple of Matidia, to clarify many details in the decoration of the theatre of Pompejus and to study some other buildings in their marble decoration. So, the connection of different parts of that important Region in Imperial Rome became more visible, mainly for the period of Domitian with his important feast of the Capitolia and further in the reign of Hadrian and the following emperors with their Dynastic cult.
