title: Effects of Clearcutting on Forage Production, Quality and Decomposition in the Caatinga Woodland of Northeast Brazil: Implications to Goat and Sheep Nutrition
Creators: name: Kirmse, Robert D.
Publisher: name: Utah State University
Year: 1984

description: Clearing of trees from the so-called caatinga woodland that characterizes the vegetation of the semi-arid region of northeast Brazil offers possibilities for increasing forage production. This research analyzed the first-year effects of clearing caatinga on dry season forage for goats and sheep. In addition, factors affecting litter decomposition on cleared and uncleared caatinga were assessed to evaluate the viability of deferring grazing of forages during the wet season for use later in the dry season.
Removing the trees resulted in a sixfold increase in production of herbaceous vegetation, however, 88 percent of the increased yield on the cleared areas was in the form of stems from herbaceous vegetation. Seventy-two percent of the stems were unpalatable to goats and sheep because of the massive size of those stems. Leaf litter from trees was an important component of the diets of goats and sheep during the dry season and clearing reduced production of this forage threefold.
Clearing resulted in increased decomposition of leaf litter. Changes in microclimate played only a minor role in this difference. The reduction in the amount of leaf litter from trees relative to litter from herbs had the greatest effect on decomposition rates of dry season forage because tree litter decomposed less rapidly than did herbaceous litter. The slow decomposition of leaf litter during the dry season suggests that deferment. of cleared or uncleared caatinga for use as forage in the latter part of the dry season is feasible.
An analysis of the diets of esophageally fistulated goats and sheep indicated that clearing may be a viable alternative for improving the amount and the in vitro dry matter digestibility of the forage consumed during the dry season the first-year post-treatment. These increases were attributed to an absolute greater abundance of preferred herbaceous forages (i.e., foliage and leaf litter) and to the persistent green foliage on coppicing woody plants. Dietary nitrogen appeared to limit intake, and clearing did not improve availability of this nutrient to sheep and goats at the higher levels of grazing pressure applied in this study. Other ecosystem considerations such as watershed protection and long-term community stability must also be considered in decisions to remove the tree canopy of the caatinga.

description: Image analysis tasks in computational pathology are commonly solved using convolutional neural networks (CNNs). The selection of a suitable CNN architecture and hyperparameters is usually done through exploratory iterative optimization, which is computationally expensive and requires substantial manual work. The goal of this article is to evaluate how generic tools for neural network architecture search and hyperparameter optimization perform for common use cases in computational pathology. For this purpose, we evaluated one on-premises and one cloud-based tool for three different classification tasks for histological images: tissue classification, mutation prediction, and grading. We found that the default CNN architectures and parameterizations of the evaluated AutoML tools already yielded classification performance on par with the original publications. Hyperparameter optimization for these tasks did not substantially improve performance, despite the additional computational effort. However, performance varied substantially between classifiers obtained from individual AutoML runs due to non-deterministic effects. Generic CNN architectures and AutoML tools could thus be a viable alternative to manually optimizing CNN architectures and parametrizations. This would allow developers of software solutions for computational pathology to focus efforts on harder-to-automate tasks such as data curation.

Year: 2019

description: This action­research project aimed to develop playing by ear in group in Functional Piano classes and understand how this practice could contribute to music learning in this discipline. The project was developed in one academic semester with two groups of five undergraduate music students who tested the new teaching­learning approach which had more emphasis on playing by ear. The action­research took place in three cycles. At the end of each cycle, an interview was held with each group in order to assess the work done and propose new teaching­learning strategies to enhance the approach. In this paper I will discuss the main findings through focus group method and the efficacy of the action­research design. The analysis of the interviews shows that: 1) results of the playing by ear practice clarified theory of existing knowledge; 2) the involvement in the project lead to powerful learning for the participants; 3) the focus on reflexivity more clearly shown what happened in the process; 4) the collaborative aspect of action research favored the group learning. From these results, it was concluded that the group discussions contributed to enhance a musical group practice and that the use of action­research in music education has great potential for improving practice.

description: We present a tetrad-affine approach to $f(\mathcal{Q})$ gravity coupled to spinor fields of spin-1/2. After deriving the field equations, we derive the conservation law of the spin density, showing that the latter ensures the vanishing of the antisymmetric part of the Einstein-like equations, just as it happens in theories with torsion and metricity. We then focus on Bianchi type-I cosmological models proposing a general procedure to solve the corresponding field equations and providing analytical solutions in the case of gravitational Lagrangian functions of the kind $f(\mathcal{Q})=α\mathcal{Q}^n$. At late time such solutions are seen to isotropize and, depending on the value of the exponent $n$, they can undergo an accelerated expansion of the spatial scale factors.

title: Diversity and Production of Herbaceous Vegetation in a Northern Utah Subalpine Chronosequence

Publisher: name: Utah State University
Year: 1981

description: Successional trends in herbaceous plant production and diversity were studied in an age sequence of sites, i.e. chronosequence, inferred to represent a meadow to aspen to fir to spruce-fir sere. Primary production was observed to decrease in a linear fashion with successional development. Three components of diversity; richness, heterogeneity, and equitability or evenness, each had low early successional values, reaching maximum diversity in mid-succession, and declining to intermediate levels with maturity. The magnitude of these trends varied greatly, depending on the methods used to determine plant dominance. Characteristics of various dominance indices and their applicability to this study were examined. Mean daily photosynthetic biomass was found to be an especially appropriate index of dominance for studying these seasonally dynamic communities. A checklist of 141 vascular plant taxa encountered in the study is included. The flora was determined to be exceedingly species rich, with values of the calculated diversity indices among the highest reported in the literature reviewed. The limitations of diversity indices to sampled data is discussed.

description: Enabling highly secure applications (such as border crossing) with face recognition requires extensive biometric performance tests through large scale data. However, using real face images raises concerns about privacy as the laws do not allow the images to be used for other purposes than originally intended. Using representative and subsets of face data can also lead to unwanted demographic biases and cause an imbalance in datasets. One possible solution to overcome these issues is to replace real face images with synthetically generated samples. While generating synthetic images has benefited from recent advancements in computer vision, generating multiple samples of the same synthetic identity resembling real-world variations is still unaddressed, i.e., mated samples. This work proposes a non-deterministic method for generating mated face images by exploiting the well-structured latent space of StyleGAN. Mated samples are generated by manipulating latent vectors, and more precisely, we exploit Principal Component Analysis (PCA) to define semantically meaningful directions in the latent space and control the similarity between the original and the mated samples using a pre-trained face recognition system. We create a new dataset of synthetic face images (SymFace) consisting of 77,034 samples including 25,919 synthetic IDs. Through our analysis using well-established face image quality metrics, we demonstrate the differences in the biometric quality of synthetic samples mimicking characteristics of real biometric data. The analysis and results thereof indicate the use of synthetic samples created using the proposed approach as a viable alternative to replacing real biometric data.

description: Armed with a new solution to the four-body problem, we reanalyze the recent Innsbruck observation of an Efimov resonance in three-body collisions of cesium atoms, and show that it provides evidence of new, universal four-body physics as well. Our theoretical treatment of four bosonic atoms in the limit of strong two-body attraction suggests a ubiquitous result: namely, that resonantly-bound states of all four atoms should occur whenever the two-body scattering length is a specific fraction (0.43) of the value where a three-body Efimov resonance occurs. A hitherto unanalyzed feature in the 2006 Innsbruck experiment supports this universal prediction, and it provides the first known evidence to date that a direct four-body recombination process plays a role. While we confirm the conclusion reached previously by some studies that no true Efimov effect exists for four particles, we demonstrate the existence of a universal class of four-body states that are intimately connected with three-body Efimov states.

Determination of volcanic aerosols from Aurora Basin North, an ice core from East Antarctica
Creators: name: Glor, CL
Publisher: name: University Of Tasmania
Year: 2023

description: Volcanic eruptions are important natural drivers of short term climate changes and knowledge of their effects will lead to a greater understanding of how the climate system works under future human induced changes. Defining small and moderate eruptions can be challenging and appears to be dependent on individual ice core site characteristics, leading to some confusion regarding their climatic impacts. In this study, ice core aerosol records from a new inland East Antarctica site, Aurora Basin North (ABN), were compared to other Antarctic sites using ternary plots to investigate the characteristics of sea salts. At ABN, the most dominant mode in the ternary plots was sulfate rich, sea salt deficient, indicating the site is heavily influenced on additional sources of sulfate with minimal influence of sea salts. In the period 1800-2000CE, a total of eight volcanic eruptions were identified, in agreement with other ice cores. Despite this, the dominance of sulfate lead to difficulty in separating small eruptions from the background sulfate and a weak seasonal cycle. The sulfate record at ABN provides for a useful volcanic ice core record, particularly for estimating the magnitude of the moderate and large eruptions. By using ternary plots and the ABN sulfate record, characteristics for a useful volcanic ice core record were identified. The ice core site should be where the seasonal sea salt record is maintained and the overall influence of sources other than volcanic sulfate is minimal.

title: The Influence of Winter Social Behavior on the Habitat Selection and Reproductive Success of the Black-billed Magpie
Creators: name: Reese, Kerry P.
Publisher: name: Utah State University
Year: 1982

description: This study examined the influence of winter social behavior, particularly dominance relationships, on the subsequent nesting habitat selection and reproductive success of Black-billed Magpies (Pica ~ hudsonia) on 2 areas in northern Utah. Hierarchical cluster analysis ordinated the habitats available to breeding birds and Chi-square and Bonferoni-z statistics were used to determine those habitat types the magpies seemed to prefer. Social status was determined by observing color-banded birds engaged in agonistic encounters at winter bait stations. Social dominance was evaluated by% dyads won, not by total % victories. Relationships between winter social status of magpies and their subsequent breeding habitat use and reproductive performance was tested by Kenda 11 's Tau. Winter foraging flocks were comprised primarily of juvenile (1st year) birds while adults tended to remain as isolates or in pairs. Social status within flocks was correlated with age and sex; males dominated females and juvenile males dominated adult males. This was caused by differences in the social organization of adults and juveniles which created asymmetric views of winter food resources between male age classes. Breeding territories were densely packed in all habitats with a mean size of 0.5 ha. Date of clutch initiation was significantly correlated with clutch size and number of fledglings, with earlier nests more successful. Juveniles occupied marginal habitats and produced fewer offspring than adults. Within a dominance hierarchy of juvenile males, no significant differences in reproductive variables were detected except date of clutch initiation and weight of nestlings. Nestlings of dominant parents fledged earlier and were heavier than those of subordinates, which should increase post-fledging survival. This study has documented, for the first time in a free-living population, relationships between characteristics of nestlings and their future dominance status. Two characteristics, fledging date and rank (by weight) in the brood, were correlated with future winter dominance of juvenile males. The dominance status of male magpies is associated with many factors related to relative fitness, with hereditary components moderated by environmental and social factors.
title: The Interaction of Ultraviolet-B Radiation Stress and Plant Competition in Agricultural Plant Populations
Creators: name: Gold, Warren Glenn
Publisher: name: Utah State University

description: The effect of ultraviolet-B radiation enhancement upon the competitive interactions of two species pairs was studied in the field. Wheat (Triticum aestivum L. 'Bannock') was paired with wild oat (Avena fatua L.) and jointed goatgrass (Aegilops cylindrica Host) to represent competition between species pairs in agricultural situations. Specially modulated ultraviolet lamp systems provided either low ultraviolet-B enhancement (simulation of a 16 % ozone layer reduction based upon the generalized plant action spectrum), high ultraviolet-B enhancement (40 % ozone reduction) or control (ambient solar ultraviolet-B) irradiance. Ultraviolet-B radiation enhancement significantly altered the competitive interactions of the species pairs. However, ultraviolet-B enhancement did not affect total shoot biomass production 1n the mixtures or shoot biomass production of the species 1n monoculture. The direction 1n which competitive interactions were altered appeared to be dependent upon the time at which the seeds were planted. Also, water stress affected some aspects of the interaction between ultraviolet-B enhancement and plant competition but the manner of this effect was inconsistent. Reproductive effort of the species was generally not affected by ultraviolet-B enhancement, except in wild oat plants under interspecific competition.

description: Large areas of European peatlands have been drained for agriculture, but drained organic soils are a strong source of carbon dioxide (CO2). Reinstalling high water tables would inhibit further peat oxidation and reduce CO2 and nitrous oxide (N2O) emissions, but most cash crops do not grow in waterlogged conditions. Paddy rice cultivation could offer a new option for continuing the agricultural use of these soils under wet conditions. However, paddy rice cultivation is known to be a strong source of methane (CH4), which might cancel out the potential climate benefit from reduced CO2 and N2O emissions. The main aim of this study was, therefore, to quantify for the first time the greenhouse gas (GHG) balance of paddy rice grown on organic soil in the temperate climate zone of the Swiss Plateau.

In an outdoor mesocosm experiment, we measured the greenhouse gases CO2, CH4, and N2O with manual chambers on a weekly to biweekly interval for one year. During the experiment, rice (Oryza sativa L.) was cultivated under flooded conditions with mid-season drainage on organic soil. As a reference treatment, ley was grown on drained organic soil (water table -100 cm).

Preliminary results from the growing season (April - October) including planting and harvest suggest that the overall GHG balance of paddy rice cultivation on organic soil (9.3 ± 1.9 t CO2 eq. ha-1 including harvest exports) was significantly lower than of ley grown on drained organic soil (27.9 ± 5.0 t CO2 eq. ha-1 including harvest exports). This difference was mainly attributed to the strong reduction in ecosystem respiration under flooded conditions compared to ley on drained organic soil. Paddy rice cultivation was a source of methane (49.2 ± 19.7 kg CH4 ha-1), while the drained organic soil covered with ley was a CH4 sink (-0.6 ± 0.1 kg CH4 ha-1). The flooded conditions in the paddy rice mesocosms significantly lowered N2O emissions (0.7 ± 0.3 kg N2O ha-1) compared to drained grassland (4.7 ± 3.1 kg N2O ha-1). N2O and CH4 accounted for 16.0 ± 6.8 % of the total GHG balance in the rice on organic soil treatment, whereas it was only 4.9 ± 2.6 % in the ley on drained organic soil.

Together, we show that paddy rice cultivation on organic soil is a valid alternative to upland agriculture in the temperate zone and offers significant GHG emission reduction potentials.

description: Brown trout (Salmo trutta), demonstrated an avoidance response to a range of intensities of artificial ultraviolet radiation in a laboratory setting. UV field measurements were made under a variety of riparian canopies in a mountain river system. UV values at various depth regimes were compared with laboratory response values. Results suggested that ultraviolet light could be a factor in the absence of brown trout in particular habitat types at various times during the daylight hours. Visible light intensity response values were also obtained under the same experimental and field conditions. These data suggested that visible light also could be a contributing factor in the absence of brown trout in different habitat types. Visible light may be of equal importance to ultraviolet light in eliciting an avoidance response in brown trout.
It is not that easy! The cross­meter genres in Flamenco

description: It is often said in Spain that Sevillana and Fandango de Huelva are music genres in triple time (3/4), but this is, at least, a half truth, such as describing a period of a year as a mere succession of days, without mentioning weeks or months. In 1966, the musicologist Hipólito Rossy put us on the trail of the real metric structure of Sevillana: "The most particular of sevillanas is the rhythmic combination. The singing is clearly in binary meter, while dancing is in ternary" (1998: 265). After Rossy, this combination has also been identified in Fandango de Huelva by Fernández (2004) and Hurtado (2009), as well as relating to Jota by Manzano (2007) and Castro (2014). At the same time, it has been one of the main issues of my musicological research on Flamenco, recently published as a digital audiobook (Jiménez de Cisneros 2015). In this article (originally presented as a lecture­recital), we will identify through embedded audio clips and graphic examples the binary and ternary elements displayed in Sevillana and Fandango de Huelva, the cross­meter genres of Flamenco, focusing on the guitar accompaniment and the melodic design. Through a pulse­level analysis, we will also look at the metric hierarchy between these elements, leading us to the cross­meter formula, which involves an alternative interpretation of compound meter. Finally, some characteristic hand clapping patterns will be included, so as the reader can approach these puzzling genres from the same point of view of the performer.

description: I review the progress made in extracting transport properties of the quark-gluon plasma from lattice QCD simulations. The information on shear and bulk viscosity, the "low-energy constants" of hydrodynamics, is encoded in the retarded correlators of Tmunu, the energy-momentum tensor. Euclidean correlators, computable on the lattice, are related to the retarded correlators by an integral transform. The most promising strategy to extract shear and bulk viscosity is to study the shear and sound channel correlators where the hydrodynamic modes dominate. I present preliminary results from a comprehensive study of the gluonic plasma between 0.95Tc and 4.0Tc.

description: We present new ALMA continuum and spectral observations of the MUSE Ultra Deep Field (MUDF), a $2\times 2$ arcmin$^2$ region with ultradeep multiwavelength imaging and spectroscopy hosting two bright $z\approx 3.22$ quasars used to study intervening gas structures in absorption. Through a blind search for dusty galaxies, we identified a total of seven high-confidence sources, six of which with secure spectroscopic redshifts. We estimate galaxy dust and stellar masses ($M_{\rm dust}\simeq 10^{7.8-8.6}\,M_{\odot}$, $M_{\star}\simeq 10^{10.2-10.7}\,M_{\odot}$), as well as star formation rates (${\rm SFR}\simeq 10^{1.2-2.0}\,M_{\odot}\,{\rm yr^{-1}} $) which show that most of these galaxies are massive and dust-obscured similar to coeval (sub-)millimeter galaxies. All six spectroscopically-confirmed galaxies are within $500~\rm km~s^{-1}$ of metal absorption lines observed in the quasar sightlines, corresponding to $100\%$ association rate. We also find that four of these galaxies belong to groups in which they are among the most massive members. Within the multiple group galaxies associated to the same absorption system, the ALMA sources are not always the closest in projection, but they are often aligned with the gaseous structures in velocity space. This suggests that these massive galaxies occupy the center of the potential well of the gas structures traced in absorption. However, albeit the low number density of sources identified with ALMA, our study may indicate that absorbers seem to infrequently originate in the inner circumgalactic medium of these galaxies. Instead, they appear to be better tracers of the gas distributed in the large-scale structure that host them.

description: Galaxy groups constitute the most common class of galaxy systems in the known Universe, unique in terms of environmental properties. However, despite recent advances in optical and infrared observations as well as in theoretical research, little is known about magnetic fields and the associated continuum radio emission. Studies on this issue have only been conducted in recent years, and many questions have yet to be resolved. This article aims to put the study of group magnetism in a broader context, to present recent advances in the field (mainly achieved with low-frequency radio interferometers), and to list the issues that need to be addressed in future observations. To make it easier for the Readers to get acquainted with the concepts presented in the manuscript, radio observations of two sample groups of galaxies are also presented.

title: Comparisons of Snow Deposition, Soil Temperature, Matric Potential and Quasi-friction Velocity Between a Windward Site and a Lee Shelter in a Cold Desert
Creators: name: Neuber, Harvey L.
Publisher: name: Utah State University
Year: 1984

description: Regimes of snow depth, soil temperature, soil matric potential and quasi-friction velocity in a windward site and a lee shelter were examined. The differences were analyzed from a biological perspective to .characterize each location in terms of site favorability to plant growth. The chronology of wind and precipitation events was investigated.
Snow depth was measured with a system of stakes arranged around and in the interior of a rectangular plot encompassing both a windward site and a lee shelter. Soil temperature, soil matric potential and water potential were measured along a transect which originated in the windward site and terminated in the lee shelter. Soil temperature and water potential were measured by thermocouple psychrometer. Mattie potentials was determined by the pressure-plate method. The regimes of quasi-friction velocity at both ends of the transect were determined by the logarithmic profile method, invoking similarity theory. Wind speed and temperature were measured at two heights in each site. A computer program was used to search the wind and precipitation records and ·categorize and sun the precipitation events by wind direction.
The lee shelter exhibited tendencies toward theoretical optima of site favorability. The horizontal distribution of snow maxima was found. to be a function of wind direction at the time of each precipitation event as well as the interaction of wind and the topographical features.
Snow was observed to accumulate to a greater depth in the lee shelter than in the windward site. Mean soil temperature over the study period was 8.5° C in the lee shelter while the windward site was 8.0° C. Soil temperature in the lee shelter was never observed to go below 0° C under a snowpack. The range of soil matric potential in the lee shelter was found to be about 14 atm at a depth of 20 cm and about 17 atm at a depth of 50 cm over the summer season. In the windward site the range of soil matric potential was approximately 30 atm at a depth of 20 cm and about 21 atm at a the 50 cm depth over the same period. The lee shelter exhibited lower (less negative) matric potentials than the windward site. These results were not corroborated by the measurement of water potential by thermocouple psychrometers. In the layer from 1.5 to 4.1 m, the mean quasi-friction velocity in the lee shelter was 39 cm s-1, favoring snow deposition there over the windward site where the mean friction velocity was 21 cm s-l. In the 0 m to 1. 5 m layer, mean friction velocity in the windward site was found to be 55 cm s-1.while the lee shelter mean was 48 cm s-1. These results indicate a distinct seperation of flow downwind of the windward site where the lee shelter resides in the turbulent wake of the windward site.

description: Recently, rotation sensors utilizing the nuclear spins of nitrogen-vacancy color centers in diamond have been demonstrated. However, these devices are power-intensive and challenging to integrate into small chip-based radiofrequency antennas and circuits necessary for controlling nuclear spins or producing relatively high magnetic fields. To address this issue, the coherent manipulation of nuclear spins via coherent population trapping at moderate magnetic fields using microwave fields has been successfully demonstrated in isotopically pure diamond. In this work, we demonstrate that a similar technique can be applied to a diamond plate with a natural abundance of carbon-13, which holds significant potential for practical sensing applications. Although the forbidden resonances required for coherent control were only partially observed, coherent population trapping was successfully demonstrated at both visible and invisible transitions, with an apparent contrast of up to 98+-11% and a true contrast of approximately 35+-7%. This finding confirms the feasibility of coherent nuclear spin control even in diamond plates with naturally occurring carbon-13
On the Orbital Velocity of Isolated Galaxy Pairs: a test of gravity in the low acceleration regime

description: The dynamics of isolated galaxy pairs represents an important tool to investigate the behavior of gravity in the low acceleration regime. Statistical analysis of a large sample of galaxy pairs led to the noticeable discovery of a region of preferred 3-dimensional velocities centered at $\sim 150$ km/s and $\sim 100$ km/s wide, a feature hard to justify in the context of numerical simulations of cosmological structure formation. It is shown here that such a feature is expected within the framework of the Modified Newtonian Dynamics, which, however, predicts it to be centered at $\sim$ 170 Km/s.

description: The growth in data traffic and the increased demand for quality of service had generated a large demand for network systems to be more efficient. The introduction of improved routing systems to meet the increasing demand and varied protocols to accommodate various scales of challenges in network efficiency had further complicated the operations. This means that a better mode of intelligence has to be infused into networking for smoother operations and better autonomic features. Cognitive networks are defined and analyzed in this angle. They are identified to have the potential to deal with the future user related quality and efficiency of service at optimized levels. The cognitive elements of a system like perception, learning, planning, reasoning and decision forming can enable the systems to be more aware of their environment and offer better services. These approaches are expected to transform the mode of operation of future networks.

title: Seed Reserves in Stockpiled Topsoil on a Coal Mine Near Kemmerer, Wyoming
Creators: name: Johnson, Cynthia K.
Publisher: name: Utah State University
Year: 1984

description: The objectives of this study were to determine how seed reserves varied with depth in topsoil stockpiles and to evaluate the effect of length of time of storage on the number of viable seeds and number of species of seeds. Soil samples were taken from five topsoil piles representing zero to three years of storage on the Elkol-Sorenson mine near Kemmerer in southwestern Wyoming. Seeds were extracted using flotation/separation methods and were tested for viability using 2,3,5-triphenyl tetrazolium chloride solution. Data were analyzed using nonparametric statistical tests. Overall density of seeds in topsoil piles was low. No relationship was found between depth into the topsoil pile and the number of seeds or species. The number of seeds and species in the topsoil pile showed no decrease with increasing length of time of storage. The proportion of annual species in the seed reserve was not shown to increase with length of time of storage. Comparisons were made between the species composition of the seed reserve in the topsoil piles and the species composition of vegetation on sites selected to represent the sites of origin of the topsoil. Factors affecting the density, species composition and species richness of stored topsoil were suggested to be the plant community on the soil to be removed, depth of soil removed, and timing of topsoil removal.

description: The search for resonant absorption of the Primakoff solar axions by $^{169}$Tm nuclei have been performed. Such an absorption should lead to the excitation of low-lying nuclear energy level: $A+^{169}$Tm $\to ^{169}$Tm$^*$ $\to ^{169}$Tm$ + γ$ (8.41 keV). The Si(Li) detector and $^{169}$Tm target placed inside the low-background setup were used for that purpose. As a result, a new restriction on the axion-photon coupling and axion mass was obtained: $g_{Aγ}({GeV}^{-1})\cdot m_A(eV)\leq1.36\cdot10^{-5}$ (90% c.l.). In model of hadronic axion this restriction corresponds to the upper limit on axion mass - $m_A\leq$ 191 eV for 90% c.l.

description: Most observers now agree that the start of Stage Three of Economic and Monetary Union (EMU) was a success. Attention must now once again focus on the conditions, and the policies, that are needed to ensure the success of the single monetary policy over a longer time horizon. Several conditions must be in place for this to be achieved. In this paper attention is focused on three such conditions, all of which are of major importance and have attracted considerable attention in the recent past. First and foremost, consideration is given to the question as to whether the euro area corresponds to what economists (most notably, the recent Nobel laureate Robert Mundell) have called an optimum currency area . Second, attention is focused on the differences in economic and financial structures, as well as on the related implications for monetary policy transmission in the euro area. This is followed by an exploration of the issue of whether policy preferences and objectives in the euro area are sufficiently homogeneous; in this context, existing empirical evidence that monetary policy rules have tended to become more mutually consistent among the participating NCBs during the preparatory stages of EMU is reviewed.
Geochemistry of bedrock and soils in the vicinity of the Anvil Mine, Yukon Territory

description: Cambrian (?) schists and phyllites of the Anvil Range, Yukon Territory, host three large stratabound lead-zinc deposits: Faro, Vangorda, and Swim. Because geological exploration is limited by a thick cover of glacial overburden, geochemical techniques were tested in the area. These include bedrock sampling for primary halos and geochemical marker horizons, and glacial overburden sampling for secondary dispersion patterns. Multi-element geochemistry of bedrock indicates that the schists and phyllites are not distinctive in one or any combination of the trace elements analyzed. However, some younger rocks are enhanced in various elements: amphibolite in Ni, Cr, Co, and Cu; rhyolite in Pb and Sn; and granite in Sn. Despite presence of glacial overburden, the trace element content of bedrock is reflected in soils. Soils overlying magnetic greenstones are enriched in Ni and Cu, whereas soils overlying granite are slightly enriched in Sn content. Detailed bedrock, overburden and soil sampling.at the Faro deposit reveals that primary Pb, Zn, Mo, and Ba halos exist about the ore zone. Mo parallels the visible alteration envelope, but Pb and Zn extend 100 feet into the hanging wall and 300 feet into the footwall. Ba extends 75 feet into the hanging wall but is not detected in the footwall. Secondary dispersion patterns are primarily related to the proximity of the Faro ore zone and type of parent material sampled. Till deposits have higher background and threshold values for Cu, Pb, and Zn than those of glaciofluvial deposits. Bath Pb and Zn distributions in overburden delineate the Faro #2 ore body; Zn extends to surface whereas Pb, in some cases, does not. This is a reflection of the type of overburden sampled. In general, Zn is the more consistent indicator of ore. The Zn anomaly is primarily hydromorphic in origin, cxZn having higher anomalous/threshold contrast than total Zn (11.1 for cxZn vs 4.8 for total Zn). The nature of the Pb anomaly is not understood.
