Carpophilus brachypterus

description: Carpophilus brachypterus (Say, 1825) Sunbury Co.: near Sunpoke Lake, 45.7658°N, 66.5546°W, red oak forest, on flowers of Viburnum cassinoides, (3, RWC); York Co.: Charters Settlement, 45.8395°N, 66.7391°W, 19.VI.2004, R.P. Webster, mixed forest, on mountain ash flowers, (1, RWC); same locality, 29.VIII.2007, mixed forest, in pile of corncobs and cornhusks, (1, RWC); Canterbury, near Browns Mountain Fen, 45.8964°N, 67.6273°W, 8.IX.2007, mixed forest, on flowers of Aster umbellatus, (1, RWC). Carpophilus brachypterus has been recorded in Canada from Manitoba east to Québec and Nova Scotia (McNamara 1991; Majka and Cline 2006), and in the United States from New Hampshire south to North Carolina and west to Texas, Nebraska, Kansas, Iowa, and South Dakota (Parsons 1943; Chandler 2001). Price and Young (2006) found them on flowers of plum (Prunus americana Marsh.), choke cherry (P. virginiana L.), apple (Pyrus malus L.) (Rosaceae), everlasting (Antennaria neglecta Greene), and white snakeroot (Eupatorium rugosum Houtt.) (Asteraceae), in leaf litter, on rotting fruit, recently cut hardwoods, on driftwood, scotch pine (Pinus sylvestris L.), white pine (Pinus strobus L.) (Pinaceae), and willow (Salix sp., Salicaceae) in a wide variety of forested and open habitats. Dillon and Dillon (1961) list the species from black haw (Viburnum prunifolium L., Caprifoliaceae).

description: We explore the rotational feature of deformed halos by performing the angular momentum projection (AMP) on the ground state wave functions obtained from the deformed relativistic Hartree-Bogoliubov theory (DRHBc) in continuum. The DRHBc+AMP approach self-consistently describes the coupling between single particle bound states and the continuum not only in the ground state but also in rotational states. The rotational modes of deformed halos in $^{42}$Mg and $^{44}$Mg are investigated by studying properties of rotational states such as excitation energy, configuration, and density distribution. Our study demonstrates that the deformed halo structure persists from the ground state in the intrinsic frame to collective states. Especially, the typical behavior of shape decoupling effects in rotating deformed halo nuclei is revealed.

description: We analyze tunneling of Cooper pairs across voltage biased asymmetric single-Cooper-pair transistors. Also tunneling of Cooper pairs across two capacitively coupled Cooper-pair boxes is considered, when the capacitive coupling and Cooper pair tunneling are provided by a small Josephson junction between the islands. The theoretical analysis is done at subgap voltages, where the current-voltage characteristics depend strongly on the macroscopic eigenstates of the island(s) and their coupling to the dissipative environment. As the environment we use an impedance which satisfies Re[Z]<

description: We show that a field emission tip electron source that is triggered with a femtosecond laser pulse can generate electron pulses shorter than the laser pulse duration (~100 fs). The emission process is sensitive to a power law of the laser intensity, which supports an emission mechanism based on multiphoton absorption followed by over-the-barrier emission. Observed continuous transitions between power laws of different orders are indicative of field emission processes. We show that the source can also be operated so that thermionic emission processes become significant. Understanding these different emission processes is relevant for the production of sub-cycle electron pulses.

description: The adsorption properties of free base 5,10,15,20-tetrakis(p-cyanophenyl)porphyrin (2H-TCNPP) on thin films of rock salt (rs) CoO(100) on Au(111) was studied in ultra-high vacuum by a combination of low-temperature scanning tunneling microscopy and spectroscopy (STM/STS) and density functional theory (DFT). Films of rs-CoO(100) on Au(111) are prepared with excellent quality in a suitable thickness range. Particularly, we found that films of only 1 nm thickness show a semiconducting energy gap of $E_\mathrm{g}=(2.5\pm 0.2)\,\textrm{eV}$. Upon deposition at 300 K, 2H-TCNPP adsorbs flat-lying and self-assembles in a long-range ordered superstructure that is stable at 80 K. The adsorption geometry of the molecules on the surface and within the self-assembly is analyzed by DFT. We find that the self-assemblies are stabilized by hydrogen bridge bonding via the functional cyano groups. Our STS data shows molecular states within the fundamental gap of the CoO. By comparison with the calculated DOS we determine the energetic positions of the frontier orbitals and find that the first three LUMO states 2H-TCNPP are located within the band gap, whereas the HOMO is shifted 1 eV below the CoO conduction band edge. Upon annealing to 420 K the molecules change their appearance in STM images and a new prominent electronic state located at the center of the molecule is formed. We interpret this changed configuration as Co-TCNPP created by self-metalation on the oxide surface.

description: Für den Abbruch der Tragkonstruktion liegen Normen und Richtlinien vor. Im Gegensatz dazu existiert für die vorgelagerten Beräumungsarbeiten (Entrümpelung, Entkernung und Schadstoffsanierung) nur wenig Fachliteratur und deren Ausführung wird im Normenwerk nur partiell angesprochen. Eine strukturierte Vorbereitung und Ausführung dieser Arbeiten ist in der Praxis kaum erkennbar. Die vorliegende Forschungsarbeit leistet einen Beitrag zur Wissensanreicherung und Verbesserung der Planung sowie der Ausführung von Beräumungsarbeiten und einer damit einhergehenden Reduktion von Abfallstoffen. Hierzu wird eine normativ begründete Gliederungs-struktur für die Beräumungsprozesse entwickelt, um eine einheitliche Verständnisbasis zu schaffen. Für den Bereich des Abbruchs der Tragkonstruktion liegt mit der DIN 18007:2000-05 eine normativ begründete Definition der Abbruchverfahren vor, von denen allerdings nur einige wenige bei der Beräumung Anwendung finden können. Daher werden die Arbeitsverfahren der Beräumung empirisch bestimmt und in Anlehnung an bestehende Grundlagen definiert. Auf Basis der Festlegung der Beräumungsverfahren erfolgen im Anschluss systematische Baustellenstudien und –analysen. Die gewonnenen Erkenntnisse zu den verschiedenen Teilarbeitsprozessen wurden in das Prozessmodell Beräumung eingeordnet, das wiederum einen schnellen Überblick über die verschiedenen Beräumungsprozesse und deren Zusammenhänge gibt. Entsprechende Teilarbeitssysteme wurden gebildet. Im Zuge von Baustellenstudien wurden darüber hinaus Kennzahlen der Beräumungsprozesse ermittelt, die eine Bewertung dieser ermöglichen. Die gewonnenen Kennzahlen wurden in dem neu entwickelten digitalen Werkzeug Bewertungsmatrix Beräumung gespeichert und stehen den Anwenderinnen und Anwendern zur Verfügung. Somit kann mithilfe von wenigen Angaben zum untersuchten Beräumungsobjekt mit vertretbarem Aufwand eine Prognose zu den Ausführungsmengen, zur Ausführungsdauern sowie zu den Kosten gegeben werden.
The Secular Evolution of a Close Ring-Satellite System: The Excitation of Spiral Density Waves at a Nearby Gap Edge

description: The Lagrange planetary equations are used to study to secular evolution of a small, eccentric satellite that orbits within a narrow gap in a broad, self-gravitating planetary ring. These equations show that the satellite's secular perturbations of the ring will excite a very long-wavelength spiral density wave that propagates away from the gap's outer edge. The amplitude of these waves, as well as their dispersion relation, are derived here. That dispersion relation reveals that a planetary ring can sustain two types of density waves: long waves that, in Saturn's A ring, would have wavelengths of order 100 km, and short waves that tend to be very nonlinear and are expected to quickly damp. The excitation of these waves also transports angular momentum from the ring to the satellite in a way that damps the satellite's eccentricity e, which also tends to reduce the amplitude of subsequent waves. The rate of eccentricity damping due to this wave action is then compared to the rates at which the satellite's Lindblad and corotation resonances alter the satellite's e. These results are then applied to the gap-embedded Saturnian satellites Pan and Daphnis, and the long-term stability of their eccentricities is assessed.

Webster, mixed forest, in pile of corncobs and cornhusks (local corn), (8, RWC). In Canada this adventive species has been recorded from British Columbia east to Québec (McNamara 1991), and in the United States it is widely distributed from Washington and California east to Texas and Florida and north to Wisconsin and Maine; also in Alaska (Parsons 1943; Downie and Arnett 1996; Chandler 2001). Horn (1879) remarked that the species was “widely distributed over the region east of the Rocky Mountains.” The species was reported from Nova Scotia by Majka and Cline (2006) but only as an intercepted species found on imported corn (Zea mays L., Poaceae). This cosmopolitan species has been found on a vast assortment of fresh and dried fruits and stored products including dried fruits such as apples, apricots, bananas, figs, prunes and raisins; fresh fruits and vegetables such as apples, apricots, oranges, dates, grapefruits, limes, maize, melons, pineapples, pears, peaches, persimmons, plums, and tomatoes; on grape skins, sugar, honey, grain, bread, biscuits, rice, avocado seeds, cotton seeds, shelled peanuts, corn meal, sorghum, cloves, and other spices (Hinton 1945).

Learning optimal linear filters for edge detection
Creators: name: Sun, Xiaofang
Publisher: name: University of British Columbia
Year: 2010

description: Edge detection is important both for its practical applications to computer vision as well as its relationship to early processing in the visual cortex. We describe experiments in which the back-propagation learning algorithm was used to learn sets of linear filters for the task of determining the orientation and location of edges to sub-pixel accuracy. A model of edge formation was used to generate novel input-output pairs for each iteration of the training process. The desired output included determining the interpolated location and orientation of the edge. The linear filters that result from this optimization process bear a close resemblance to oriented Gabor or derivative-of-Gaussian filters that have been found in primary visual cortex. In addition, the edge detection results appear to be superior to the existing standard edge detectors and may prove to be of considerable practical value in computer vision.
Effect of rotation on the tachoclinic transport

Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We study the effect of rotation on sheared turbulence, due to differential rotation. By solving quasi-linear equations for the fluctuating fields, we derive turbulence amplitude and turbulent transport coefficients, taking into account the effects of shear and rotation on turbulence. We focus on the regions of the tachocline near the equator and the poles where the rotation and the shear are perpendicular and parallel, respectively. For parameter values typical of the tachocline, we show that the shear reduces both turbulence amplitude and transport, more strongly in the radial direction than in the horizontal one, resulting in an anisotropic turbulence. The rotation further reduces turbulence amplitude and transport at the equator whereas it does not have much effect near the pole. The interaction between the shear and the rotation is shown to give rise to a novel non diffusive flux of angular momentum, possibly offering a mechanism for the occurrence of a strong shear region in the solar interior.

description: The differential response of chiral molecules to incident left- and right- handed circularly polarized light is used for sensing the handedness of molecules. Currently, significant effort is directed towards enhancing weak differential signals from the molecules, with the goal of extending the capabilities of chiral spectrometers to lower molecular concentrations or small analyte volumes. Previously, optical cavities for enhancing vibrational circular dichroism have been introduced. Their enhancements are mediated by helicity-preserving cavity modes which maintain the handedness of light due to their degenerate TE and TM components. In this article, we simplify the design of the cavity, and numerically compare it with the previous one using an improved model for the response of chiral molecules. We use parameters of molecular resonances to show that the cavities are capable of bringing the vibrational circular dichroism signal over the detection threshold of typical spectrometers for concentrations that are one to three orders of magnitude smaller than those needed without the cavities, for a fixed analyte volume. Frequency resolutions of current spectrometers result in enhancements of more than one order (two orders) of magnitude for the new (previous) design. With improved frequency resolution, the new design achieves enhancements of three orders of magnitude. We show that the TE/TM degeneracy in perfectly helicity preserving modes is lifted by factors that are inherent to the cavities. More surprisingly, this degeneracy is also lifted by the molecules themselves due to their lack of electromagnetic duality symmetry, that is, due to the partial change of helicity during the light-molecule interactions.

DRLDO: A novel DRL based De-ObfuscationSystem for Defense against Metamorphic Malware

description: In this paper, we propose a novel mechanism to normalize metamorphic and obfuscated malware down at the opcode level and hence create an advanced metamorphic malware de-obfuscation and defense system. We name this system DRLDO, for Deep Reinforcement Learning based De-Obfuscator. With the inclusion of the DRLDO as a sub-component, an existing Intrusion Detection System could be augmented with defensive capabilities against 'zero-day' attacks from obfuscated and metamorphic variants of existing malware. This gains importance, not only because there exists no system to date that uses advanced DRL to intelligently and automatically normalize obfuscation down even to the opcode level, but also because the DRLDO system does not mandate any changes to the existing IDS. The DRLDO system does not even mandate the IDS' classifier to be retrained with any new dataset containing obfuscated samples. Hence DRLDO could be easily retrofitted into any existing IDS deployment. We designed, developed, and conducted experiments on the system to evaluate the same against multiple-simultaneous attacks from obfuscations generated from malware samples from a standardized dataset that contains multiple generations of malware. Experimental results prove that DRLDO was able to successfully make the otherwise un-detectable obfuscated variants of the malware detectable by an existing pre-trained malware classifier. The detection probability was raised well above the cut-off mark to 0.6 for the classifier to detect the obfuscated malware unambiguously. Further, the de-obfuscated variants generated by DRLDO achieved a very high correlation (of 0.99) with the base malware. This observation validates that the DRLDO system is actually learning to de-obfuscate and not exploiting a trivial trick.

description: Punctuation restoration is an important post-processing step in automatic speech recognition. Among other kinds of external information, part-of-speech (POS) taggers provide informative tags, suggesting each input token's syntactic role, which has been shown to be beneficial for the punctuation restoration task. In this work, we incorporate an external POS tagger and fuse its predicted labels into the existing language model to provide syntactic information. Besides, we propose sequence boundary sampling (SBS) to learn punctuation positions more efficiently as a sequence tagging task. Experimental results show that our methods can consistently obtain performance gains and achieve a new state-of-the-art on the common IWSLT benchmark. Further ablation studies illustrate that both large pre-trained language models and the external POS tagger take essential parts to improve the model's performance.

description: Some time ago it was my privilege to have the responsibility to prepare the traditional protocol that is an initial step in some of the events in which Elders lead their people. In this case, I was in the company of the respected Elder, Art Raining Bird, from Rocky Boy, Montana. At that point, the setting was very informal. I looked at him and the realization of who was sitting there made me realize how little I knew. He was sitting in the room where I was preparing the protocol, his white hair down to his shoulders. I thought of the tremendous respect in which he was held by his own people, the profound and detailed knowledge he had of our culture. His stature as spiritual leader in the community was more like that of an institution than a person. He knew what I was doing, but was not watching me intrusively. It was as though he were just noticing, but not noticing. I thought of how poorly I knew how to complete my task, and thought “What am I doing, trying to prepare the protocol? I don't know how to do this properly and in the presence of a person who has seen this countless times and knows all its significance!''

description: We present multi-frequency radio observations of a sample of z~2 obscured (type-2) quasars in the Spitzer extragalactic First Look Survey area. We combine the public data at 1.4 GHz, used in the selection of these sources, with new observations at 610 MHz (GMRT) and at 4.9 GHz (VLA). We find the sample includes sources with steep, flat and gigahertz-peaked spectra. There are no strong correlations between the presence or absence of emission lines in the optical spectra and the radio spectral properties of the sample. However, there are no secure flat-spectrum type-2 quasars with narrow emission lines which would be problematic for unified schemes. Most of the population have straight radio spectra with spectral index alpha~1 as is expected for developed, potentially FRI-like, jets in which continous injection of relativistic electrons is accompanied by inverse-Compton losses against the cosmic microwave background.

The technique used in the first-year and three-year analysis now finds 390 point sources, and the five-year source catalog is complete for regions of the sky away from the galactic plane to a 2 Jy limit, with SNR > 4.7 in all bands in the least covered parts of the sky. The noise at high frequencies is still mainly radiometer noise, but at low frequencies the CMB anisotropy is the largest uncertainty. A separate search of CMB-free V-W maps finds 99 sources of which all but one can be identified with known radio sources. The sources seen by WMAP are not strongly polarized. Many of the WMAP sources show significant variability from year to year, with more than a 2:1 range between the minimum and maximum fluxes.

description: We investigate the confinement and long-term dynamics of the magnetised solar tachocline. Starting from first principles, we derive the values of turbulent transport coefficients and then explore the implications for the confinement and long-term dynamics of the tachocline. For reasonable parameter values, the turbulent eddy viscosity is found to be negative, with turbulence enhancing the radial shear in the tachocline. Both magnetic diffusivity and thermal diffusivity are severely quenched, with the values much smaller than the magnitude of the eddy viscosity. The effect of the meridional circulation on momentum transport via the hyperviscosity becomes important when the radial shear becomes large (larger than the presently inferred value) due to the negative viscosity.

description: It is shown that timelike surfaces of constant mean curvature 1 in anti-de Sitter 3-space can be constructed from a pair of Lorentz holomorphic and Lorentz antiholomorphic null curves in PSL(2,R) via Bryant type representation formulae. These formulae are used to investigate an explicit one-to-one correspondence, the so-called Lawson correspondence, between timelike surfaces of constant mean curvature 1 in anti-de Sitter 3-space and timelike minimal surfaces in Minkowski 3-space. The hyperbolic Gauss map of timelike surfaces in anti-de Sitter 3-space, which is a close analogue of the classical Gauss map is considered. It is discussed that the hyperbolic Gauss map plays an important role in the study of timelike surfaces of constant mean curvature 1 in anti-de Sitter 3-space. In particular, the relationship between the Lorentz holomorphicity of the hyperbolic Gauss map and timelike surfaces of constant mean curvature 1 in anti-de Sitter 3-space is studied.

description: In accordance with its institutional mandate, the University of Northern British Columbia has entered into partnerships of various types with both rural and urban Aboriginal communities. This article describes the processes of building partnerships between Aboriginal communities and the University at the levels of both institutions and persons. We argue that the success of these collaborations has been enhanced by overtly participatory methodologies, but recognize that these methodologies have been constrained by factors outside the collaboration pro­ cess. We suggest that successful participatory partnerships must begin with a pro­ cess of communication where all parties outline their assumptions, limitations, and objectives. Claims by non-First Nations researchers and institutions engaged in participatory processes to be disinterested or simply facilitating the goals of the Aboriginal Nations with whom they work run the risk of continuing colonial rela­tionships rather than eroding such relationships through participatory processes.

description: We employ a path integral real time approach to compute the DC conductance and spin polarization for electrons transported across a ballistic Quantum Ring with Rashba spin-orbit interaction. We use a piecewise semiclassical approximation for the particle orbital motion and solve the spin dynamics exactly, by accounting for both Zeeman coupling and spin-orbit interaction at the same time. Within our approach, we are able to study how the interplay between Berry phase, Ahronov Casher phase, Zeeman interaction and weak localization corrections influences the quantum interference in the conductance within a wide range of externally applied fields. Our results are helpful in inerpreting recent measurements on interferometric rings.

description: We investigate the environmental dependence of stellar population properties of galaxies in the local universe. Physical quantities related to the stellar content of galaxies are derived from a spectral synthesis method applied to a volume-limited sample containing more than 60 thousand galaxies extracted from the DR4 of the SDSS. Mean stellar ages, mean stellar metallicities and stellar masses are obtained from this method and used to characterise the stellar populations of galaxies. The environment is defined by the projected local galaxy density estimated from a nearest neighbour approach. We recover the star formation--density relation in terms of the mean light-weighted stellar age, which is strongly correlated with star formation parameters derived from \Ha. We find that the age--density relation is distinct when we divide galaxies according to luminosity or stellar mass. The relation is remarkable for galaxies in all bins of luminosity. On the other hand, only for an intermediate stellar mass interval (associated to a transition in galaxy properties) the relation shows a change in galaxy properties with environment. Such distinct behaviours are associated to the large stellar masses of galaxies with the same luminosity in high-density environments. In addition, the well known star formation--density relation results from the prevalence of massive systems in high-density environments, independently of galaxy luminosity, with the additional observed downsizing in galaxy formation, in which the star formation is shifted from massive galaxies at early times to low-mass galaxies as the universe evolves. Our results support that a natural path for galaxy evolution proceeds via a nurture way, in the sense that galaxy evolution is accelerated in denser environments, that took place mainly at high-redshifts.

description: We show that, for a continuous set of entangled four-partite states, the task of maximizing the payoff in the symmetric-strategy four-player quantum Minority game is equivalent to maximizing the violation of a four-particle Bell inequality with each observer choosing the same set of two dichotomic observables. We conclude the existence of direct correspondences between (i) the payoff rule and Bell inequalities, and (ii) the strategy and the choice of measured observables in evaluating these Bell inequalities. We also show that such a correspondence between Bell polynomials (in a single plane) and four-player, symmetric, binary-choice quantum games is unique to the four-player quantum Minority game and its "anti-Minority" version. This indicates that the four-player Minority game not only plays a special role among quantum games but also in studies of Bell-type quantum nonlocality.

description: The static and dynamic susceptibilities for a general class of mean field random orthogonal spherical spin glass models are studied. We show how the static and dynamical properties of the linear and nonlinear susceptibilities depend on the behaviour of the density of states of the two body interaction matrix in the neighbourhood of the largest eigenvalue. Our results are compared with experimental results and also with those of the droplet theory of spin glasses.

description: We propose and experimentally demonstrate a novel interference fading suppression method for phase-sensitive optical time domain reflectometry (Phi-OTDR) using space-division multiplexed (SDM) pulse probes in few-mode fiber. The SDM probes consist of multiple different modes, and three spatial modes (LP01, LP11a and LP11b) are used in this work for proof of concept. Firstly, the Rayleigh backscattering light of different modes is experimentally characterized, and it turns out that the waveforms of Phi-OTDR traces of distinct modes are all different from each other. Thanks to the spatial difference of fading positions of distinct modes, multiple probes from spatially multiplexed modes can be used to suppress the interference fading in Phi-OTDR. Then, the performances of the Phi-OTDR systems using single probe and multiple probes are evaluated and compared. Specifically, statistical analysis shows that both fading probabilities over fiber length and time are reduced significantly by using multiple SDM probes, which verifies the significant performance improvement on fading suppression. The proposed novel interference fading suppression method does not require complicated frequency or phase modulation, which has the advantages of simplicity, good effectiveness and high reliability.

Mineralogy, paragenesis, and mineralogic zonation of the Silver Queen vein system, Owen Lake, central British Columbia
Creators: name: Hood, Christopher Thomas Saul
Publisher: name: University of British Columbia
Year: 2010

description: The Silver Queen mine, southeast of Houston, B.C., consists of a series of epithermal base- and precious-metal bearing veins hosted by Late Cretaceous volcanic rocks of the Tip Top Hill formation. Mineralogically, the veins are complex, displaying several discrete mineralizing stages characterized by the presence of certain sulfide and gangue species. The complexity of the vein mineralogy has presented a problem in assessing the systemic evolution of the hydrothermal system. This study describes in detail the nature of the mineralogy, dividing the assemblages present into four distinct paragenetic stages. Particular attention was paid to the occurrence of potentially economic phases (e.g. electrum). Sulfide phases which were compositionally sensitive to trace element variations were examined by electron microprobe to determine variations on single grain and deposit scales. Microbeam analysis also assisted in the identification of several sulfosalt species. Evaluation of the mineralogy and paragenesis allowed for the assessment of the evolution of the deposit. Paragenetically, the mineralization is divided into four distinct stages. The first stage is characterized by fine grained pyrite and quartz mineralization, with hematite abundant in the assemblage in the central segment of the most extensive (Number Three) vein. Barite, svanbergite, and hinsdalite become abundant towards the south end of the Number Three vein, with marcasite more abundant towards the north. Stage II is dominated by the presence of massive sphalerite and layered carbonate (calcite in the south, manganoan carbonates in the north). Stage III, however, is more complex. Mineralization consists of chalcopyrite, galena, fahlores (tetrahedrite-tennantite), electrum, quartz, and sulfosalts. Included in the sulfosalt assemblage are the unusual Pb-Bi-Cu-Ag species berryite, matildite, gustavite, and aikinite. The final stage of mineralization is volumetrically minor and is dominated by fine-grained quartz, pyrobitumen, and calcite. Minor element trends in tetrahedrites and sphalerites reveal a mineralizing fluid with a high degree of compositional variability. Tetrahedrite grains show well developed oscillatory compositional zoning in Sb, As, Bi, Ag, and Cu, while sphalerites are commonly visually well layered. The latter was found to be the main repository for the unusual metals Ga, Ge, and In, which are found in anomalous levels in Silver Queen ore. The Silver Queen veins are proposed to have evolved from fluids originating at depth to the south of the Number Three vein. Pulses of metal-bearing fluids interacted with cooler groundwaters, producing the observed distribution of assemblages. The presence of Ga, Ge, and In may have been sourced in an organic-rich layer exposed in several locales in the Silver Queen mine area.
