description: We study numerically the time evolution of the transport properties of layered superconductors after different preparations. We show that, in accordance with recent experiments in BSCCO performed in the second peak region of the phase diagram (Portier et al, 2001), the relaxation strongly depends on the initial conditions and is extremely slow. We investigate the dependence on the pinning center density and the perturbation applied. We compare the measurements to recent findings in tapped granular matter and we interpret our results with a rather simple picture.

description: Semi-gem quality corundum crystals are formed in a syenite pegmatite dyke in the Alvand igneous-metamorphic complex in west Iran. The dyke is intruded the igneous rocks and the surrounding hornfelses. Corundum is mainly associated with K-feldspar in the rocks and makes crystals 2 to 60 mm across. It shows gray, bluish-gray, pale blue, ink blue and dark blue colours. The crystals show colour zoning and trapiche-like zoning in hand specimens and under the microscope. The main mineral phase inclusions in corundum crystals are muscovite, phlogopite, hercynite and Nb-Ta oxides. LA-ICP-MS and electron microprobe analyzes indicate wide range of Fe/Mg, Fe/Ti, Ti/Mg and Ga/Mg ratios for the analyzed crystals while variation of Cr/Ga ratio is limited. The high Fe and Ga and low Mg and Cr contents suggest a magmatic origin for these corundums. Ti content was found as the main factor controlling the colour.

description: We initiate the study of Brane Gas Cosmology (BGC) on manifolds with non-trivial holonomy. Such compactifications are required within the context of superstring theory in order to make connections with realistic particle physics. We study the dynamics of brane gases constructed from various string theories on background spaces having a K3 submanifold. The K3 compactifications provide a stepping stone for generalising the model to the case of a full Calabi-Yau three-fold. Duality symmetries are discussed within a cosmological context. Using a duality, we arrive at an N=2 theory in four-dimensions compactified on a Calabi-Yau manifold with SU(3) holonomy. We argue that the Brane Gas model compactified on such spaces maintains the successes of the trivial toroidal compactification while greatly enhancing its connection to particle physics. The initial state of the universe is taken to be a small, hot and dense gas of p-branes near thermal equilibrium. The universe has no initial singularity and the dynamics of string winding modes allow three spatial dimensions to grow large, providing a possible solution to the dimensionality problem of string theory.

description: In the paper, an investigation of copper metallurgical slags found in the South Urals and dating to the Bronze Age between 4000 and 1300 BCE is carried out. Four main mineralogical types are distinguished according to their mineral composition: Cr-rich spinel containing olivine, sulphide-containing olivine, sulphide containing glassy and pyroxene type. First type of slags is composed of zoned olivine, magnetite and glass having relicts of Cr-rich spinels and serpentinites that indicate the use of azurite-malachite ores from ultrabasic rocks. These finds were determined in sites of the Early Yamna period in the Cis-Urals and are widespread in Sintashta culture. The second type is composed of skeletal olivine crystals, magnetite and wüstite with copper sulphides droplets. It type belongs to Alakul period. The raw material sources are sulphide ores from a secondary enrichment zone of VMS, skarn and Cu-porphyry deposits. The sulphide containing glassy type is mainly composed of glass with copper and sulphide droplets. The slags were recovered in the Srubna sites. The raw material sources were rich sulphide ores of cupriferous sandstones. The pyroxene type is composed of augite, pigeonite and/or wollastonite with a small amount of glass and sulphide inclusions. According to the composition of glass, slags can be distinguished into the Cis-Uralian type, including cupriferous sandstones, and Trans-Uralian type having various volcanogenic-hydrothermal deposits as raw materials. Essential Ca, P, Ba and REE impurities in slag glass demonstrate the use of barite, calcite and bone fluxes. The phase diagrams, crystallisation temperatures and experimental data revealed that slag melt temperatures ranged between 1150–1300 ° C.

description: We have investigated electronic structures of a room temperature diluted magnetic semiconductor : Co-doped anatase $\rm TiO_{2}$. We have obtained the half-metallic ground state in the local-spin-density approximation(LSDA) but the insulating ground state in the LSDA+$U$+SO incorporating the spin-orbit interaction. In the stoichiometric case, the low spin state of Co is realized with the substantially large orbital moment. However, in the presence of oxygen vacancies near Co, the spin state of Co becomes intermediate. The ferromagnetisms in the metallic and insulating phases are accounted for by the double-exchange-like and the superexchange mechanism, respectively. Further, the magnetic ground states are obtained for Mn and Fe doped $\rm TiO_{2}$, while the paramagnetic ground state for Ni-doped $\rm TiO_{2}$.

description: For decades, the streams and rivers in northern areas of Pakistan are being explored for gold but the source rock for primary gold is yet to be located. Recent geological surveys have identified several areas for follow-up study for Cu-Au mineralization in Chitral and Gilgit-Baltistan regions. The rocks exposed at various localities are variably altered and/ or mineralized and intensely deformed, which mostly include diorite, granodiorite, greenschists, limestones and undeformed volcanic rocks and granitoids of the Kohistan island arc. The results of petrographic and X-ray diffraction (XRD) analyses of a variety of representative rock samples from a number sites have revealed that mineralization in the Chitral and Gilgit-Baltistan regions is dominantly in the form of pyrite, tetrahedrite, chalcopyrite and galena with subordinate amounts of magnetite, malachite and azurite. The associated/ gangue minerals include albite, quartz, actinolite, biotite, chlorite, epidote, calcite, garnet, illite and titanite (sphene). Diffraction patterns of glycolated samples did not show the existence of swelling clay (e.g., smectite). Sericitic, chloritic and carbonatic alterations have been observed in the studied altered rocks. Mass balance calculations indicate that most of the sulfide-bearing samples are enriched in Cu, Au, Sb, As and Pb and depleted in the rest of the metals reflecting differences in elements mobility during the ore-forming processes. Some of the mineralized rocks especially limestone have experienced a significant volume change due to mobilization of some of the major element oxides e.g. CaO, Fe2O3, SiO2 and ore-forming components e.g. Cu and Pb. The mineralization is of epithermal type in most of the investigated sites, however a few areas show ore formation though orogenic processes and very rarely the ore deposit displays features of the volcanogenic massive sulfide type. Some of the areas are quite promising with respect to their ore element contents and the highly mineralized zones lie in close proximity to major structures in the region. Besides, results from the current study indicate that the mineralization shows close spatial association and hence a strong genetic link with strike slip faults especially where they bend and merge together.

description: We report a resonant inelastic x-ray scattering study of the dispersion relations of charge transfer excitations in insulating La$_2$CuO$_4$. These data reveal two peaks, both of which show two-dimensional characteristics. The lowest energy excitation has a gap energy of $\sim 2.2$ eV at the zone center, and a dispersion of $\sim 1$ eV. The spectral weight of this mode becomes dramatically smaller around ($π$, $π$). The second peak shows a smaller dispersion ($\sim 0.5$ eV) with a zone-center energy of $\sim 3.9$ eV. We argue that these are both highly dispersive exciton modes damped by the presence of the electron-hole continuum.

Prediction of economic potential of deep blind mineralization by Fourier transform of a geochemical dataset
Creators: name: Mahdiyanfar, Hossein
Publisher: name: Periodico di Mineralogia
Year: 2020

description: The identification of blind and disseminated mineral deposits is an important challenge in mining exploration. This research presents a quantitative approach to predict a deep, hidden disseminated mineralization using a novel approach named frequency coefficient method (FCM) in mining geochemistry. In deep mineral deposits, the processes of ore formation generate geochemical anomalies at the surface, which have distinct wavelengths and frequencies. The mineralization processes especially deep mineral deposits create geochemical anomalies at the surface with different wavelengths and frequency signals. These deposits can be detected using geochemical signal processing by Fourier transform and interpretation of these frequency signals. In particular, analysis of the geochemical dataset in the frequency domain (FD) proves to be an effective tool for identifying deep ore-formation processes, and hence potentially discovering a hidden mineralization at depth before borehole drilling is carried out. In this study, we apply the FCM to a geochemical dataset made of 104 soil and whole rock elemental analyses from the Au-bearing vein system of Tanurcheh (Khaf-Daruneh belt, north-east Iran) to predict the uneconomic nature of that Au mineralization at depth. Such conclusion has been tested and validated by the Au grade distribution of six exploration boreholes.

description: We locate putative global minima for (C_60)_N clusters modelled by the potential of Pacheco and Prates-Ramalho up to N=105. These minima are based on icosahedral packing up to N=15, but above this size the lowest-energy structures are decahedral or close-packed. Although structures based on the 98-molecule Leary tetrahedron, which have been inferred from experiment, are not lowest in energy for this potential, an examination of the energetics of a growth sequence leading to the Leary tetrahedron lends further support to the experimental assignments. An analysis of the potential energy surface topography and the thermodynamics of two example clusters indicates that the multiple-funnel topography is likely to have a strong influence on the dynamics of structure formation and that solid-solid transitions driven by differences in vibrational entropy are likely to be common.

Geochronology, geochemistry, and petrogenesis of the Dongshadegai K-feldspar granite in the northern margin of the North China Craton, China: Implications for Indosinian magmatism and related Au mineralization

description: As representative examples of alkaline magmatism and related mineralization in the northern margin of the North China Craton, the gold deposits within the Hadamengou Au-enriched region are dominated by K-feldspar-quartz vein-type gold mineralization. In contrast, the Dongshadegai pluton in the northern part of this region mainly consists of K-feldspar granite. In this study, we determined the U-Pb zircon age of the Dongshadegai pluton to be 235±3 Ma (MSWD = 2.1), indicating that this pluton was produced by middle Indosinian magmatism. The lithogeochemical properties of the Dongshadegai pluton are characterized by a high silica contents (SiO2, 70.4−72.5%); K enrichment (K2O/Na2O, 1.12−1.25); alkaline enrichment (K2O+Na2O, 8.95−9.52%); weakly peraluminous properties (Al2O3, 13.83−14.8%); light rare earth element enrichment (LREE/HREE, 18.04−21.65); weakly negative Eu anomalies (δEu, 0.61−0.76); Nb, Ta, P, Ti, and Sr depletions; and K, La, Ce, and Hf enrichments. Thus, the overall lithogeochemistry of the Dongshadegai pluton resembles that of A-type granite, indicating that the pluton originated from an alkaline-enriched magma. According to the regional tectonic evolutionary history and the geochemical properties of the pluton, we conclude that the Dongshadegai pluton formed in an extensional fault setting after a tectonic collision, and its corresponding age is consistent with the formation times of both the Hadamengou gold deposits and the Xishadegai Mo deposits. Based on a comprehensive analysis of the results of recent studies of regional tectonic magmatism and metallogenic processes, we show that a large-scale Au-Mo mineralization event occurred that was related to Indosinian tectonic magmatism on the northern margin of the North China Craton, which requires special attention because it differs from regional Late Mesozoic mineralization processes.

description: We explore quantum dynamics in Floquet many-body systems with local conservation laws in one spatial dimension, focusing on sectors of the Hilbert space which are highly polarized. We numerically compare the predicted charge diffusion constants and quantum butterfly velocity of operator growth between models of chaotic Floquet dynamics (with discrete spacetime translation invariance) and random unitary circuits which vary both in space and time. We find that for small but finite polarization per length (in the thermodynamic limit), the random unitary circuit correctly predicts the scaling of the butterfly velocity but incorrectly predicts the scaling of the diffusion constant. We argue that this is a consequence of quantum coherence on short time scales. Our work clarifies the settings in which random unitary circuits provide correct physical predictions for non-random chaotic systems, and sheds light into the origin of the slow down of the butterfly effect in highly polarized systems or at low temperature.

description: Quite rare pottery shards showing a paste rich in black sand particles, possibly igneous minerals, have been discovered in late Republican Roman sites of Trieste area (NE Italy) and SW Slovenia in the Caput Adriae. Most of them belong to late Greco-Italic and Dressel 1 amphora types, in use from the end of the 3rd and the beginning of 1st centuries BC. Following a methodological procedure based on the analysis of igneous temper, proved to be particularly effective by several scholars, numerous minerals have been extracted from the surface of 16 pottery shards, without causing any visible damage to them. Microprobe analysis has allowed the identification of igneous minerals (olivine, clinopyroxene, feldspar and garnet), most likely originating from the Roman or Campanian magmatic provinces. The chemistry of garnets, indicated in the past as a possible tracer of ancient commerce but no longer used in the last decades to study Italian late Republican pottery, has proved to be a promising tool to distinguish among the two magmatic provinces. According to our study, most of the investigated garnets-bearing samples would originate from Somma-Vesuvius while some of them from Latium.

description: We analyse the possibility of charge breaking minima developing in the Higgs triplet model, and under what conditions they are deeper than charge-preserving ones. Analytical expressions relating the depth of minima of different types are deduced. A global symmetry of the model leads to increased stability for charge-preserving vacua. However, if that symmetry is broken by a soft term, deeper charge-breaking minima may occur more easily. We identify the vev configurations most likely to produce charge breaking minima.

description: For a detailed characterization of the 5.7 106 mt phosphogypsum (PG) stack in the vicinity of Bacau city, Romania, the air dose rate (ADR) was measured in 72 points covering the stack surface, while 10 samples of stack material were collected for future analysis. Radiometric determinations showed for the ADR values varying between 364 ± 53 and 489 ± 8 nSv/h, with some extreme values of 2775 ± 734 nSv/h, significantly exceeding 90 nSv/h, the average value reported for the Romanian territory. High-resolution gamma-ray spectroscopy (HRGS), performed on 10 samples collected from the entire PG stack evidenced only the presence of 226Ra as the major radioactive element with a specific activity varied between 820 ± 150 and 5278 ± 264 Bq/kg for hot spots. Further analysis performed on a similar number of samples by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), X-ray fluorescence (XRF), scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (EDX), evidenced, beside gypsum as the main component, traces of brushite (CaHPO4·2H2O) and ardealite (Ca2(PO3OH)(SO4)·4H2O), as well as the presence of small acicular celestine (SrSO4) agglomerates. XRF determinations of the mass fractions of major elements evidenced values such as SiO2 (2.31 ± 0.73 %), TiO2 (0.07 ± 0.01 %), Al2O3 (0.17 ± 0.04 %), Fe2O3 (0.87 ± 0.18 %), MnO (0.01 ± 0.01 %), MgO (0.17 ± 0.02 %), CaO (32.5 ± 0.82 %), Na2O (0.04 ± 0.04 %), K2O (0.05 ± 0.01 %), P2O5 (2.12 ± 0.51 %), LOI (20.2 ± 0.3 %), i.e. closer to literature reported data for PG of different provenience while the data concerning the distribution of 20 trace elements, including incompatible Sc, La, Ce, and Th were relatively closer to the upper continental crust (UCC).
Stable propagation of an ordered array of cracks during directional drying

description: We study the appearance and evolution of an array of parallel cracks in a thin slab of material that is directionally dried, and show that the cracks penetrate the material uniformly if the drying front is sufficiently sharp. We also show that cracks have a tendency to become evenly spaced during the penetration. The typical distance between cracks is mainly governed by the typical distance of the pattern at the surface, and it is not modified during the penetration. Our results agree with recent experimental work, and can be extended to three dimensions to describe the properties of columnar polygonal patterns observed in some geological formations.

description: We review recent results of molecular dynamics simulations of two models of liquid water, the extended simple point charge (SPC/E) and the Mahoney-Jorgensen transferable intermolecular potential with five points (TIP5P), which is closer to real water than previously-proposed classical pairwise additive potentials. Simulations of the TIP5P model for a wide range of deeply supercooled states, including both positive and negative pressures, reveal (i) the existence of a non-monotonic ``nose-shaped'' temperature of maximum density (TMD) line and a non-reentrant spinodal, (ii) the presence of a low temperature phase transition. The TMD that changes slope from negative to positive as P decreases and, notably, the point of crossover between the two behaviors is located at ambient pressure (temperature approx 4 C, and density approx 1 g/cm^3). Simulations on the dynamics of the SPC/E model reveal (iii) the dynamics at negative pressure shows a minimum in the diffusion constant $D$ when the density is decreased at constant temperature, complementary to the known maximum of D at higher pressures, and (iv) the loci of minima of D relative to the spinodal shows that they are inside the thermodynamically metastable regions of the phase-diagram. These dynamical results reflect the initial enhancement and subsequent breakdown of the tetrahedral structure and of the hydrogen bond network as the density decreases.

description: In this article, we describe petrological, mineralogical and typological analyses of handmade pottery recovered from the Bronze Age site of Cap de Barbaria II, which is located on the island of Formentera (Balearic Islands, Spain). In addition, the mineralogy and texture of several clay deposits present within the study area are also characterized using X-ray powder diffraction and laser diffraction particle size analysis. The goals of this research are, first, to identify the different technological choices made by the community of potters that inhabited this settlement in various stages of the chaîne opératoire (i.e., the procurement of raw materials, preparation of pastes, shaping of the vessels, and firing); second, we aim to determine the relationships between the technological choices identified at this site and the prehistoric technological traditions observed on the other islands of the Balearic archipelago. The results provide evidence that the Bronze Age potters from Cap de Barbaria II developed a very cohesive production system for the procurement of raw materials and the paste recipes used to produce the vessels. Moreover, the results indicate a clear preference for the long-term use of decalcified clays and spathic calcite temper, thus reflecting a consistent community of practice among the potters that shared several technological choices with artisans located at other sites on Formentera and other islands within the archipelago.

description: The lack of theoretical understanding of X-Ray Absorption Near Edge Structure (XANES) spectroscopy makes the development of analysis tools for its study a necessity. Here, an algorithm for judicious choice of local minima and maxima points of XANES spectrum (experimental or simulated) is proposed, without any loss of information on peaks location nor on peak strength. We call it the Rising Sun Envelope Method, since it is based on successive regularizations of the spectral measurement that, according to parameter choices that are intrinsic to the measurements, keep peaks location and strength as invariants. This is the first method that finds peaks in XANES automatically, without depending on first derivative information. Nevertheless, a direct computation of Absorption-Edge is provided, where we avoid the issue inflection point computations based on the XANES second derivative, dealing instead with simpler computations of inflection points of higher quality cubic spline approximation. Besides applications of the algorithm to XANES, we illustrate further applications in Electron Energy Loss Spectroscopy (EELS) and Raman spectra.

description: The decorative wall painting from 17th CE Chatta Chowk was investigated to study the composition and characteristics of the pigment used in the decorative arts. The pigments were examined by thin cross-sections, High-Resolution X-ray diffraction (HR-XRD) analysis, Fourier-transform infrared spectroscopy (FTIR) and, portable Raman spectrometry. Besides, gas chromatograph-mass spectrometry (GC-MS) was used for identifying pigment binders. Analysis results showed the stratigraphy of the paint layer applied over fine lime plaster in a well-controlled manner mixed with binders according to the secco technique. The identified pigments for red paint layers were attributed to the mixture of hematite (Fe2O3), cinnabar (HgS) and cadmium sulfide (CdS). The utilization of admixture of mercury, iron and cadmium compounds has served as a clear evidence in order specific tones on the painted surfaces. The green paint layer was attributed to green earth (celadonite) through vibrational features, differentiating from glauconite spectra. The GC-MS analysis of the pigment showed the use of fats, waxes and drying oils as binders.

description: We have investigated the spatial distribution, and the properties and chemical composition of the dust orbiting HD 100546. This system is remarkably different from other isolated Herbig Ae/Be stars in both the strength of the mid-IR excess and the composition of the circumstellar dust. We speculate that the formation and spatial distribution of the crystalline dust observed in the HD 100546 system may be linked to the formation of a proto-Jupiter in the disk around HD 100546. Such a proto-Jupiter could gravitationally stir the disk leading to a collisional cascade of asteroidal sized objects producing small crystalline grains, or it could cause shocks by tidal interaction with the disk which might produce crystalline dust grains through flash heating. As shown by Malfait et al. (1998), the infrared spectrum of HD 100546 is very similar to that of C/1995 O1 Hale-Bopp (Crovisier et al. 1997). Using an identical methodology, we have therefore also studied this solar system comet. Both objects have an almost identical grain composition, but with the important difference that the individual dust species in Hale-Bopp are in thermal contact with each other, while this is not the case in HD 100546. This suggests that if similar processes leading to the dust composition as seen in HD 100546 also occurred in our own solar system, that Hale-Bopp formed after the formation of one or more proto-gas giants.
