Year: 2019

description: O período que se sucedeu ao 25 de Abril de 1974 foi uma época de mudança para o país. Verificaram-se alterações sociais, demográficas e culturais, que se refletiram em muitos organismos públicos. A FNAT, fundada no Estado Novo para apoiar as políticas do regime, é um exemplo das políticas culturais estado-novistas. Após Abril de 1974, foi reformulada dando origem ao INATEL que continuou a intervir nas mesmas áreas porém assumindo uma postura de apoio e de dinamização das actividades permitindo aos envolvidos uma outra dinâmica de acção. Esta comunicação procura apresentar e analisar os eventos de música popular organizados pela instituição com o objectivo de dinamizar as actividades locais e de facilitar encontros entre os grupos. Através de um mapeamento das acções da INATEL, identificando programas de apoio, participantes, cronologias, e planos de actividade entre 2008 a 2017, pretendo discutir o âmbito das políticas dirigidas para a música popular e as motivações por trás desse plano de acção. A pesquisa sobre a acção da INATEL nas práticas musicais associativas insere-se num estudo que está a ser desenvolvido no âmbito do Doutoramento em Antropologia, complementado com recurso a trabalho de campo, pesquisa bibliográfica e entrevistas a algumas figuras responsáveis pelo planeamento das actividades apresentadas.

description: Event-based vision sensors encode local pixel-wise brightness changes in streams of events rather than image frames and yield sparse, energy-efficient encodings of scenes, in addition to low latency, high dynamic range, and lack of motion blur. Recent progress in object recognition from event-based sensors has come from conversions of deep neural networks, trained with backpropagation. However, using these approaches for event streams requires a transformation to a synchronous paradigm, which not only loses computational efficiency, but also misses opportunities to extract spatio-temporal features. In this article we propose a hybrid architecture for end-to-end training of deep neural networks for event-based pattern recognition and object detection, combining a spiking neural network (SNN) backbone for efficient event-based feature extraction, and a subsequent analog neural network (ANN) head to solve synchronous classification and detection tasks. This is achieved by combining standard backpropagation with surrogate gradient training to propagate gradients through the SNN. Hybrid SNN-ANNs can be trained without conversion, and result in highly accurate networks that are substantially more computationally efficient than their ANN counterparts. We demonstrate results on event-based classification and object detection datasets, in which only the architecture of the ANN heads need to be adapted to the tasks, and no conversion of the event-based input is necessary. Since ANNs and SNNs require different hardware paradigms to maximize their efficiency, we envision that SNN backbone and ANN head can be executed on different processing units, and thus analyze the necessary bandwidth to communicate between the two parts. Hybrid networks are promising architectures to further advance machine learning approaches for event-based vision, without having to compromise on efficiency.

title: Training Parents in Descriptive Assessment and Function Identification
Creators: name: Sip, Makenzie
Publisher: name: Utah State University

description: It is often difficult for parents to address their child’s problem behavior. Children with special needs can display more frequent and intense problem behavior. Therefore, professionals need to help parents of children with special needs identify how to decrease their child’s problem behavior. Professionals help to decrease problem behavior by performing assessments called descriptive assessments to identify why the problem behavior is happening, and then using these assessments to create an appropriate plan of how to prevent and respond to the problem behavior. We examined if parents could be taught the skills necessary to perform descriptive assessments and then use these assessments to choose appropriate ways to treat the problem behavior. Parents included four parents of children with autism spectrum disorder. Video vignettes of child actors displaying various problem behaviors were used to assess the parents’ ability to perform a descriptive assessment, figure out why the problem behavior was happening, and then use this assessment to choose appropriate ways to get the problem behavior to decrease. These skills were assessed prior to a training class and then following a training class where the parents were taught how to perform the skills. In order for parents to be able to use these skills in their everyday lives, it is important that they can apply the skills to their own children. Therefore, a video vignette of each parents’ child displaying problem behavior was used to see if the parents could apply what they had learned in the training class to their own child. Results varied for participants. Therefore, it is unknown whether the training class in the current study helped parents to learn to perform a descriptive assessment to figure out why a problem behavior is happening and then use the assessment to identify ways to decrease the problem behavior. More research is needed to teach parents to apply these skills to their own children.
title: Population Dynamics and Net Production of Brown Trout (Salmo trutta) in Two Areas of a High Gradient Mountain Stream

Year: 1978

description: Estimates of the brown trout (Salmo trutta) population were made in two areas of the Blacksmith Fork River, Cache County, Utah, from June 1972 to June 1973. Additional data were obtained on movement, growth, mortality, biomass, production, and yield.
Population density was highly variable in the area where habitat alterations had occurred, but was relatively uniform where the habitat was undisturbed. The brown trout exhibited little movement except during spawning season. Instantaneous growth and mortality rates are provided for each age group.
Mean annual biomass in the two areas was 12.0 and 10.2 grams per square meter and production was estimated at 9.2 and 7.7 grams per square meter per y ear in the two study areas. Gametes comprised approximately 5 percent of the annual production and angler harvest removed 39 percent of production.
Role of triad interactions in spectral evolution of surface gravity waves in deep water

description: It is generally accepted that the evolution of deep-water surface gravity wave spectrum is governed by quartet resonant and quasi-resonant interactions. However, it has also been reported in both experimental and computational studies that non-resonant triad interactions can play a role, e.g., generation of bound waves. In this study, we investigate the effects of triad and quartet interactions on the spectral evolution, by numerically tracking the contributions from quadratic and cubic terms in the dynamical equation. In a finite time interval, we find that the contribution from triad interactions follows the trend of that from quartet resonances (with comparable magnitude) for most wavenumbers, except that it peaks at low wavenumbers with very low initial energy. This result reveals two effects of triad interactions: (1) the non-resonant triad interactions can be connected to form quartet resonant interactions (hence exhibiting the comparable trend), which is a reflection of the normal form transformation applied in wave turbulence theory of surface gravity waves. (2) the triad interactions can fill energy into the low energy portion of the spectrum (low wavenumber part in this case) on a very fast time scale, with energy distributed in both bound and free modes at the same wavenumber. We further analyze the latter mechanism using a simple model with two initially active modes in the wavenumber domain. Analytical formulae are provided to describe the distribution of energy in free and bound modes with numerical validations.

N.M.R. study on single crystals of lead and thallium
Creators: name: Schratter, Jacob Jack
Publisher: name: University of British Columbia
Year: 2011

description: A study of the Knight shift and indirect coupling constants has been carried out on single crystals of lead and thallium. In lead, the exchange-narrowing model of Anderson and Weiss has been shown to be inapplicable. The angular variation of the second moment has established that the contribution from the second-nearest neighbours is very small, and values are obtained for the pseudoexchange and pseudodipolar coefficients for the first-nearest neighbours, which are in good agreement with the theoretical values of Tterlikkis, Mahanti, and Das. A small anisotropy of the Knight shift which has the expected angular dependence has been observed for the first time in a cubic metal, In thallium, the isotropic Knight shift decreases with increasing temperature, showing a nonlinear variation which is most pronounced between 50° and 150°K. This behaviour is correlated with the anomalous pressure dependence of the superconducting transition temperature at low pressures. From the superconducting data on pure Tl and Tl-Hg alloys we extract the volume dependence of the electronic density of states, and use it to derive the temperature dependence of the Knight shift. The results agree well with the observed data. We have measured the angular dependence of the linewidth in thallium and related it to the second moment to estimate the pseudodipolar and pseudoexchange contributions for the first two shells of neighbours. These values are very different, despite the fact that both shells have nearly the same radius, and this establishes experimentally for the first time an orientation dependence of the indirect coupling constants.
Weathering of soil parent material controls quantity and quality of soil organic carbon in alpine ecosystems
Creators: name: Moser, Maria

description: In the global carbon cycle, organic matter in soils represents the major terrestrial pool of carbon, storing roughly twice the amount of carbon as do the atmosphere and vegetation combined. However, under changing environmental conditions, it remains unclear whether soils act as sources or sinks of carbon. Especially soils in alpine ecosystems are subject to undergo changes in their soil organic carbon (SOC) stocks. To disentangle the possible effects of climate change on SOC stocks in alpine environments, the factors which contribute to SOC stabilization have to be known and understood. Recent studies indicated the importance of soil physicochemical parameters governed by weathering of parent material.

To attain a better understanding of how parent material may influence SOC stabilization in alpine ecosystems, five alpine sites in Europe with varying parent material (i.e., Dolomite, Flysch, Gneiss, Greenschist, and Marl) were investigated. Similar climatic conditions, aspect, and slope allowed to analyze the impact of different parent materials on SOC stocks. The geochemical composition of the parent material and the soil, exchangeable cations and effective cation exchange capacity, pH, pedogenic oxides, soil texture, organic carbon and nitrogen contents, and SOC fractions were determined for all soil horizons (i.e., Oh, Ah, Bv, and Cv). The following SOC fractions were physically separated: unprotected, coarse particulate organic carbon (>250 µm), SOC occluded in microaggregates (53 – 250 µm), and SOC in the silt and clay fraction (<53 µm), which is assumed to be predominantly protected via minerals. Linear and non-linear models were computed in order to distill the relative importance of the geochemical parameters on SOC concentrations in the bulk soil (SOCbulk) and the silt and clay fraction (SOCs+c).

Preliminary findings point at the importance of soil depth, texture, and organically complexed oxides as these parameters were found to be among the best predictors for SOCbulk. The concentrations of poorly crystalline aluminum, magnesium, and exchangeable manganese gained importance when predicting SOCs+c. These results align with previous research which has shown the influence of pedogenic oxides on SOC stabilization, Furthermore, the significance of soil depth supports the increasing call of soil scientists to take the entire soil profile into account when analyzing SOC dynamics since large amounts of carbon are stored at depth below the commonly analyzed first 30 cm.

description: Modern spectroscopic surveys of galaxies such as MaNGA consist of millions of diverse spectra covering different regions of thousands of galaxies. We propose and implement a deep unsupervised machine learning method to summarize the entire diversity of MaNGA spectra onto a 15x15 map (DESOM-1), where neighbouring points on the map represent similar spectra. We demonstrate our method as an alternative to conventional full spectral fitting for deriving physical quantities, as well as their full probability distributions, much more efficiently than traditional resource-intensive Bayesian methods. Since spectra are grouped by similarity, the distribution of spectra onto the map for a single galaxy, i.e., its "fingerprint", reveals the presence of distinct stellar populations within the galaxy indicating smoother or episodic star-formation histories. We further map the diversity of galaxy fingerprints onto a second map (DESOM-2). Using galaxy images and independent measures of galaxy morphology, we confirm that galaxies with similar fingerprints have similar morphologies and inclination angles. Since morphological information was not used in the mapping algorithm, relating galaxy morphology to the star-formation histories encoded in the fingerprints is one example of how the DESOM maps can be used to make scientific inferences.

title: Spectral Signature Studies For Application in Deer Census Using Remote Sensing Techniques
Creators: name: Pate, Maran C.
Publisher: name: Utah State University
Year: 1979

description: This study was performed to determine the spectral signatures of deer and their natural background elements for censusing purposes. Consideration was given to atmospheric transmittance, acceptable flying weather, and terrain. Possible spectral bands between 0.3 and 14.0 μm were obtained (over a pathlength of 1500 feet at an altitude of 5000 feet) based upon atmospheric transmittance using the LOWTRAN 3B computer program. They are: 0.30 - 1.33, 1.49 - 1.79, 2.00 - 2.50, 3.00 - 3.16, 3.38 - 4.10, 4.59 - 5.05, and 8.00 - 13.33 μm, for transmittance greater than 75%. Weather conditions are favorable for flying and taking data on the average of 2 days per week (in areas near Salt Lake City) throughout the winter months. Measurements were obtained of the spectral reflectance and spectral emissivity of deer hide, sands, soils, sage brush, and other natural winter habitat elements. The results of these measurements indicate that all the biological samples tested emit blackbody radiation; that is, the emissivity is approximately unity and there are no unique spectral signatures. The reflected spectra in the region 0.5 to 1.1 μm contains considerable unique spectra, including chlorophyll absorption at 0.66 μm, that might be useful in de signing a multi spectral classifier.

description: Deforestation followed by fertilizer intensive agriculture is widely recognized as a significant contributor to anthropogenic greenhouse gas emissions (GHG), particularly carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). However, empirical studies focusing on soil GHG flux dynamics from deforestation hotspots in the tropics are still limited creating major uncertainties for constraining global GHG budgets. In this study, we investigated how deforestation for fertilizer intensive sugarcane cultivation in Uganda affects soil-borne GHGs. Therefore, soil GHG fluxes were measured in a primary forest and in a completely randomized experiment premised in the neighboring sugarcane fields with different fertilizer regimes, representing both smallholder and industrial-scale sugarcane farm management. Despite the use of different fertilization rates (low, standard, and high) as treatments for the sugarcane CRD experiment, neither auxiliary controls nor soil GHG fluxes significantly differed among the CRD treatments. Soil respiration was higher in the sugarcane than in the forest, which we attribute to the increased autotrophic respiration from the sugarcane’s fine root biomass and the likely exposure of the sugarcane’s larger soil organic carbon stocks to microbial decomposition through ploughing operations. The forest soils were a stronger net sink of CH4 than the sugarcane soils despite forest soils having both higher bulk densities and larger water-filled pore space (WFPS), and we suspect that this was due to alteration of the methanotroph abundance upon the conversion. Soil N2O emissions were smaller in the sugarcane than in the forest, which was surprising, but most likely resulted from the excess N being lost either through leaching or uptake by the sugarcane crop. Only seasonal variability in WFPS, among the auxiliary controls, affected CH4 uptake at both sites and soil CO2 effluxes in the sugarcane. Noteworthy, soil N2O fluxes from both sites were unaltered by the seasonality-mediated changes in auxiliary controls. All the findings put together suggest that forest conversion for sugarcane cultivation alters soil GHG fluxes by increasing soil CO2 emissions and reducing both soil CH4 sink strength and soil N2O emissions.

title: Interrelationships Between Benthic Macroinvertebrates and Habitat in a Mountain Stream
Creators: name: Payne, John M.
Publisher: name: Utah State University
Year: 1979

description: A study to determine habitat differences of benthic macroinvertebrates was conducted on the upper Strawberry River, Utah. The investigation was part of a large scale project to determine minimum stream flow requirements for trout. The effects of time, habitat, depth and velocity on the distribution of benthic fauna were evaluated.
Samples of benthic invertebrates (146 total) were collected every 2 months at 8 stations on the river from November, 1975 through August, 1976. Representatives of 59 taxa were collected. Eight taxa comprised 90 percent of the mean annual community standing crop in numbers. Biomass was not dominated by any group of taxa. Community standing crop decreased from late Fall 1975 until early Summer 1976. The largest increase in standing crop occurred during August.
Prediction of benthic distribution through the use of depth and velocity categories was unsuccessful. Three-dimensional plots of the relative density of a taxon versus depth and velocity indicated the contagious nature of the animals' distributions but their preference for specific categories could not be demonstrated. The results suggested that macroinvertebrates could tolerate large variations in current and depth and that these physical factors are only indirectly related to faunal distribution.
Results of analysis of variance and covariance showed time to be the factor which influenced the distribution of most taxa (85%), followed by the time x habitat interaction (20%), velocity (18%), habitat (11%), and depth (9%). Comparisons in animal abundance were made between 4 riffles and 4 ''pools". These two habitats did not differ significantly in substrate type or velocity, however depth did show significant differences. Results of nonparametric tests suggested that the majority of taxa migrated into "pools" during periods of snow, ice, and low flows, an indication that "pools" may provide refuge to macroinvertebrates during periods of stream dewatering and diversion.
Misticismo e performance musical: uma proposta interpretativa de obras para flauta de Mario Lavista e Torü Takemitsu

description: O misticismo condicionou o comportamento do ser humano desde sempre: na forma de vida, rituais, superstições, crenças religiosas ou ações inconscientes, sendo estes alguns exemplos que podemos observar na vida de qualquer pessoa. Também na música o misticismo está presente, tanto na música sacra, como noutras correntes, inclusive na música contemporánea. Como intérprete, reconheço que o misticismo influencia de alguma forma, consciente e/ou inconscientemente, a performance. A proposta interpretativa apresentada aborda duas obras para flauta solo de dois compositores contemporâneos: Mario Lavista (mexicano, 1943-) e Töru Takemitsu (japonês, 1930-1996), as quais, derivando de tradições culturais e espirituais distintas, estão ambas marcadamente influenciadas pelo misticismo. A abordagem ao misticismo é feita desde uma perspetiva figurativa e analógica das obras Lamento de Lavista e Voice de Takemitsu, mediante a sua simbologia e sonoridade na linguagem musical contemporânea. Na performance das referidas obras, pretende-se expandir as possibilidades de interpretação complementando a flauta transversal com instrumentos ancestrais, de conhecido caráter terapêutico, como gongos, taças de cristal e concha. Estes instrumentos, usados tanto no Ocidente como no Oriente para criar ambientes meditativos, são introduzidos para estimular o despertar e ampliar a sensibilidade dos sentidos, quer do intérprete, quer do ouvinte.

Response of small mammals to site characteristics in the northern midlands of Tasmania
Creators: name: Galea, LM
Publisher: name: University Of Tasmania
Year: 2023

description: Small mammals have certain requirements for survival, for example, shelter and food. Shelter is an important resource for small mammals as it can protect them from predation and environmental factors. Shelter also has the potential to supply mammals with sufficient material for nesting and cover. Food is essential for survival and provides energy for day to day activities and reproduction. A trapping study was employed to consider the relationship of the presence and abundance of three mammal groups; (1) small native mammals (irrespective of species), (2) arboreal mammals (here Trichosurus vulpecula) and (3) small native ground-dwelling mammals (Bettongia gaimardi, Isoodon obesulus, Perameles gunnii and Potorous tridactylus), with three shelter characteristics; (1) vegetation patch size, (2) overall vegetation patch complexity and the (3) vegetation structure within a patch. The study was conducted on 30 selected sites in an intensive agricultural area in the Northern Midlands of Tasmania. Vegetation patch size and overall patch complexity were found to affect significantly the presence and abundance of total small native mammals (positive association). Arboreal mammals were significantly affected by overall complexity only (positive association) and were predominately found in sites with vegetation patches consisting of a high canopy, ground and litter cover. Ground-dwelling mammals were significantly associated with increasing vegetation patch size, with similar vegetation characteristics to arboreal mammals, including high canopy, ground and litter cover. An alternative method to trapping was also used to detect bandicoot presence and abundance, a ground-dwelling mammal of particular interest, to four habitat variables; (1) vegetation patch size, (2) overall vegetation patch complexity, (3) vegetation structure within a patch (as well as gorse specifically) and ( 4) food biomass. This method was the recording of diggings, which is a characteristic of bandicoot foraging behaviour. Digging counts were made along transects established at the 30 sites used in the mammal trapping study. Bandicoots were found to be significantly associated with both patch size and overall complexity (positive association). The structure of the vegetation typical of bandicoots appeared to be high canopy, ground and litter cover. As for the presence of bandicoot diggings and gorse, results indicated that gorse was more important to bandicoots than no ground cover at all; however, diggings were even more likely at sites with ground cover but no gorse. There was a marginal effect of food biomass on the presence of bandicoot diggings.

description: Soil mineral characteristics have been shown to play a dominant role in stabilizing soil organic matter over medium to long term timescales. However, while great strides have been made (Kleber et al, 2021) toward understanding organic matter stabilization processes, there remain uncertainties about the chemistry, time scales, and age of carbon that is stored on soil minerals. We applied modern thermal analysis methods to investigate soil mineral effects on the thermal stability, chemical composition, and age distribution of soil organic matter. We selected subsoil mineral fractions that contained a single dominant stabilizing pathway (e.g. 2:1 clays, iron oxides, short-range order minerals, crystalline minerals) to isolate effects of individual minerals. We paired thermal fractionation with pyrolysis-GC/MS to describe the relationships of SOM age and chemical composition. Early results show that while certain minerals display heterogeneous thermal stabilities, single mineralogies contain generally narrow age ranges. In addition, organic matter chemistry associated with diverse minerals varies widely and indicates that certain minerals provide higher stability to complex, energy-rich molecules. Associated with this work, we also present novel continuous SOM radiocarbon distributions from thermal fractionation.

title: Two Basic Methodological Choices in Wildland Vegetation Inventories: Their Consequences and Implications
Creators: name: Shute, Donald Alan
Publisher: name: Utah State University
Year: 1979

description: In designing inventories of wildland vegetation, two of the many basic methodological choices are: 1) whether data are collected, reduced, and stored in discrete classes or as continuous variables, and 2) whether data are gathered as general purpose variables to bear upon many questions, or as specific purpose variables optimized for only one type of prediction. The effects of these two choices on accuracy of vegetation inventories to predict plant community production were examined by comparing regression models built upon differing sets of independent variables "inventoried" from a common data base. Contrary to expectations, discrete variables of classified community types were better predictors of plant community production than the same vegetation data reduced as continuous variables by three ordination techniques. Substitution of specific purpose soil and vegetation variables thought to be especially relevant to production did not improve correlations from those of analogous general purpose variables. These results do not show the anticipated accuracy loss of general purpose inventory variables, but such findings cannot yet be generalized to other situations. Implications for the design of practical, extensive survey methods for wildland vegetation are briefly discussed.

description: Analytically and quantitatively we reveal that the GLE equation, based on a memory function approach, in which memory functions and information measures of statistical memory play fundamental role in determining the thin details of the stochastic behavior of seismic systems, naturally conduces to a description of seismic phenomena in terms of strong and weak memory. Due to a discreteness of seismic signals we use a finite - discrete form of GLE. Here we studied some cases of seismic activities of Earth ground motion in Turkey with consideration of complexity, nonergodicity and fractality of seismic signals.

description: El laberinto del Fauno realizado por Guillermo del Toro expõe, através de um conto de fadas, a crueldade e violência vividas na Espanha franquista após a Guerra Civil (1936-9). Composta a partir de uma canção de embalar sem palavras, por Javier Navarrete, esta torna-se o leitmotif central de toda a composição, adquirindo uma dupla funcionalidade: de índice da vida e de índice da morte. Portanto, uma melodia que nos envolve no mundo da fantasia (índice da vida), mas que rapidamente se metamorfoseia numa canção de lamento (índice da morte), dando-nos conta dos horrores da realidade. Quais os signos que nos levam à corroboração destas afirmações? Através da análise das cenas em que diegeticamente surge a canção de embalar e tendo como referencial teórico a semiótica peirceana (Peirce 1932), este estudo pretende descortinar os vários significados intrínsecos à canção de embalar, assinalando-os, analisando-os e compreendendo-os, como leitmotif da vida e da morte, numa relação interdisciplinar com a imagem.

description: We present a second paper related to the analyses of high-dispersion spectroscopic observations of the magnetic cataclysmic variable AE Aquarii. We focus our efforts on the study of the emission lines and their radial velocities. We detect a sinusoidal behaviour, in several of the observing runs, with variable amplitudes. Of those runs presented, the velocity curve of 2000 August shows less instability in the emission material. In this case, we obtain K1 = 114 +/- 8 km s-1, which we take as our best value for the radial velocity of the primary. This result is consistent within 2sigma with previously published values obtained using indirect methods. We interpret this consistency as observational evidence of material orbiting the rapidly rotating primary star. We present a Doppler tomography study, which shows that the H alpha emission is primarily concentrated within a blob in the lower left quadrant, a structure similar to that predicted by the propeller model. However, for 2000 August, we find the emission centred around the position of the white dwarf, which supports the possibility of the K1 value of this run of being a valid approximation of the orbital motion of the white dwarf.

description: Searches for variations of fundamental constants require a comprehensive understanding of measurement errors. This paper examines a source of error that is usually overlooked: the impact of continuum placement error. We investigate the problem using a high resolution, high signal to noise spectrum of the white dwarf G191$-$B2B. Narrow photospheric absorption lines allow us to search for new physics in the presence of a gravitational field approximately $10^4$ times that on Earth. Modelling photospheric lines requires knowing the underlying spectral continuum level. We describe the development of a fully automated, objective, and reproducible continuum estimation method. Measurements of the fine structure constant are produced using several continuum models. The results show that continuum placement variations result in small systematic shifts in the centroids of narrow photospheric absorption lines which impact significantly on fine structure constant measurements. This effect should therefore be included in the error budgets of future measurements. Our results suggest that continuum placement variations should be investigated in other contexts, including fine structure constant measurements in stars other than white dwarfs. The analysis presented here is based on NiV absorption lines in the photosphere of G191$-$B2B. Curiously, the inferred measurement of the fine structure constant obtained in this paper using NiV (the least negative of our measurements is $Δα/α= -1.462 \pm 1.121 \times 10^{-5}$) is inconsistent with the most recent previous G191$-$B2B photospheric measurement using FeV ($Δα/α= 6.36 \pm 0.35_{stat} \pm 1.84_{sys} \times 10^{-5}$). Given both measurements are derived from the same spectrum, we presume (but in this work are unable to check) that this 3.2$σ$ difference results from unknown laboratory wavelength systematics.

description: Whereas bulk bismuth supports very-high mobility, light, Dirac electrons and holes in its interior, its boundaries support a layer of heavy electrons in surface states formed by spin orbit interaction in the presence of the surface electric field. Small diameter d trigonal Bi nanowires (30 nm < d < 200 nm) were studied via magnetotransport at low temperatures and for fields up to 14 T in order to investigate the role of surfaces in electronic transport. A two-dimensional behavior was expected for surface charges; however we found instead a three-dimensional behavior, with a rich spectrum of Landau levels in a nearly spherical Fermi surface. This is associated with the long penetration length of surface states of trigonal wires. The prospect of the participation of surface transport and surface-induced relaxation of bulk carriers in the electronic properties of macroscopic samples is evaluated. We show that recent observations of magnetoquantum peaks in the Nernst thermopower coefficient, attributed to two-dimensional electron gas charge fractionalization, can be more plausibly interpreted in terms of these surface states.

description: Georgia is a rich country with musical and choreographic traditions. Ajara – the region, on the example of which I will discuss music and dance performance issues - is a distinguished region due to the patterns that can be found of one, two, three or four-part songs, choreographic groups and individual performers. Transferring folklore onto the stage since the end of 19th century, resulted in a few changes of performance. For instance, Settlement of principals of European polyphony and Academic chorus, unification of song and dance ensembles, change of the manner of singing and loss of characteristic features typical to folk song. As for the dance, with complying of individual performing dance mode in existence, with interfere of choreographs and unification of different traditional dances in one composition was created large-scale, nowadays very popular Ajarian dance - Gandagana, also traditional round dance Khorumi and its versions were transformed into mass dancing patterns. In the report will be discussed history of performing Ajarian traditional music and dances, performing tendencies and principles spread in 19th-20th centuries and established today, repertoire issues, influence of stage practice on the country-side’s traditional performing, process of hereditary renewal, actualization of folklore and “producing” new creative product from it.

description: Many solid-state qubit systems are afflicted by low frequency noise mechanisms that operate along two perpendicular axes of the Bloch sphere. Depending on the qubit's control fields, either noise can be longitudinal or transverse to the qubit's quantization axis, thus affecting its dynamics in distinct ways, generally contributing to decoherence that goes beyond pure dephasing. Here we present a theory that provides a unified platform to study dynamics of a qubit subjected to two perpendicular low-frequency noises (assumed to be Gaussian and uncorrelated) under dynamical decoupling pulse sequences. The theory is demonstrated by the commonly encountered case of power-law noise spectra, where approximate analytical results can be obtained.
