title: Belowground Resource Exploitation in Semiarid Plants: A Comparative Study Using Two Tussock Grasses That Differ in Competitive Ability
Creators: name: Eissenstat, David M.
Publisher: name: Utah State University
Year: 1986

description: The relative competitive abilities of Agropyron desertorum and Agropyron spicatum were compared using Artemisia tridentata transplants as indicator plants. Although these two tussock grasses have similar shoot growth forms and shoot physiological characteristics, they have substantial differences in their competitive abilities. Artemisia had lower survival, growth, reproduction, and water potential when transplanted into neighborhoods of A. desertorum than in neighborhoods of A. spicatum. Plant attributes associated with the differences in competitive ability were explored. Agropyron desertorum and~ spicatum have remarkably similar potential growth rates at warm soil temperatures. In a prolonged cold soil temperature treatment in the greenhouse, A. desertorum had a 66% greater aboveground relative growth rate than A. spicatum. These differences, however, were not apparent for early spring tiller growth rates in the field. Distinct differences in timing of root growth were found between the two tussock grasses. Aqropyron desertorum exhibited greater root growth during winter and early spring and invaded disturbed soil space more rapidly than A. spicatum, especially if the disturbance occurred soon after the snow had melted. Similarly, A. desertorum proliferated its roots in zones of nutrient enrichment created early in the spring sooner than A. spicatum. No differences in root growth were found between species in zones of nutrient enrichment that were created later in the growing season. Despite differences in early spring root growth, water extraction and radiophosphorus acquisition early in the spring were similar for the two grass species. Later in the spring, A. desertorum extracted more water and radiophosphorus than A. spicatum. Differences in resource extraction between the two species in a specific soil layer occurred weeks before A. spicatum, but not A. desertorurn, had obtained maximum root length. Early root growth probably provides A. desertorum an important head start over A. spicatum in soil exploration each growing season. Differences in resource extraction, however, do not become apparent between the two species of Agropyron until plant demand exceeds soil supply rate to the roots.

description: A Caputo-type fractional-order mathematical model for "metapopulation cholera transmission" was recently proposed in [Chaos Solitons Fractals 117 (2018), 37--49]. A sensitivity analysis of that model is done here to show the accuracy relevance of parameter estimation. Then, a fractional optimal control (FOC) problem is formulated and numerically solved. A cost-effectiveness analysis is performed to assess the relevance of studied control measures. Moreover, such analysis allows us to assess the cost and effectiveness of the control measures during intervention. We conclude that the FOC system is more effective only in part of the time interval. For this reason, we propose a system where the derivative order varies along the time interval, being fractional or classical when more advantageous. Such variable-order fractional model, that we call a 'FractInt' system, shows to be the most effective in the control of the disease.

description: Street performance has a long history (the blind singers on the Balkan Peninsula, for example) and the history of music contains many articles, books and studies about historical music performances in open-air public places, be it street cries, barrel organ players or broadside ballads singers (Grochowski 2010, Tyllner 2001, Barański 1986 and others). While there exist some case studies about present-day music in open spaces (e.g. Tyllner 2001), busking (street music making) is a field with a lot of space for further research to conduct as it takes a different form in different cities. Differences come from a great variety of factors: weather, legal rules, musical education, character of public space, tourism, cultural and artistic potential of urban areas. The purpose of this case study is to compare these notions in several selected cities.

Reinforcing and anxiolytic-like effects of alcohol in planaria require ˜í¬¿-opioid receptor activation
Creators: name: Read, TJ
Publisher: name: University Of Tasmania
Year: 2023

description: Planaria have been used for decades as subjects for psychopharmacology research, predominantly in addiction studies involving dopamine agonists. However, this research largely focused on classical conditioning, with comparatively few studies examining how planaria behaviour is altered by alcohol administration. In humans and other mammals, ethanol enhances dopamine transmission via endogenous opioid release. This study sought to investigate the link between ethanol and endogenous opioids in planaria in a novel operant conditioning paradigm and avoidance task. Study 1 was used to determine whether 1% or 2% ethanol concentrations induced significant conditioning, with 2% showing greater effectiveness. Study 2 investigated operant conditioning with ethanol (2%), finding significant results after 4 days of reinforcement. Study 3 investigated whether the mu-opioid receptor antagonist naloxone affected conditioning induced by ethanol. Results indicated that naloxone blocked the acquisition of discrimination learning with 2% ethanol, suggesting that alcohol reinforcement in planaria necessitates mu-opioid receptor activation. Study 4 investigated the anxiolytic effect of ethanol in planaria, finding significant increases in light tolerance when ethanol was administered. These novel results indicate that planaria are a valuable animal model for ethanol research and that potential future alcohol abuse medications might be validly tested in this species for preliminary efficacy studies.
title: Using Computer Imaging to Assess Visual Impacts of Forest Insect and Disease Pests
Creators: name: Rabin, Daniel
Publisher: name: Utah State University
Year: 1989

description: Forest insect and disease pests alter the appearance of trees, thereby impacting visual resources. Because of the complexity of most forest landscapes, the degree of visual impact of pest-infested forest stands is difficult to quantify.
This paper describes a method of measuring visual impacts of pest-infested forest stands. Photographs of healthy Ponderosa pine trees were entered into a computer video-image-processing system. Using this system, images of trees were altered to simulate different degrees of infestation by limb rust, a forest pathogen.
The altered and unaltered images were shown to groups of observers who rated the scenes in terms of "scenic beauty." The great majority of individuals were able to detect a change in the appearance of trees infected with limb rust disease even when only small sections of a tree were altered. There was also general agreement within the groups of observers that the presence of limb rust disease had a detrimental effect on the visual quality of the forest scenes. The tests also suggested that the location of infestation in the tree crown, the amount of crown mortality, and the number of infected Ponderosa pine in a stand influenced the degree to which visual quality was impacted.
Evolution of minimum-bias parton fragmentation in nuclear collisions

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Minimum-bias fragment distributions (FDs) are calculated by folding a power-law parton energy spectrum with parametrized fragmentation functions (FFs) derived from $e^+$-$e^-$ and p-p collisions. Changes in FFs due to parton "energy loss" or "medium modification" are modeled by altering FF parametrizations consistent with rescaling QCD splitting functions. The common parton spectrum is constrained by comparison with a p-p $p_t$ spectrum hard component. In-vacuum and in-medium FDs are compared with spectrum hard components from 200 GeV Au-Au collisions for several centralities. The reference for all nuclear collisions is the FD derived from in-vacuum $e^+$-$e^-$ FFs. The hard component for p-p and peripheral Au-Au collisions is found to be {\em strongly suppressed} for smaller fragment momenta, consistent with the FD derived from in-vacuum p-p FFs. At a particular centrality the Au-Au hard component transitions to enhancement at smaller momenta and suppression at larger momenta, consistent with FDs derived from in-medium $e^+$-$e^-$ FFs. Fragmentation systematics suggest that QCD color connections change dramatically in more-central A-A collisions. Spectrum systematics are inconsistent with saturation-scale arguments and parton thermalization.

description: We developed a convolutional neural network (CNN) model to distinguish the double-lined spectroscopic binaries (SB2s) from others based on single exposure medium-resolution spectra ($R\sim 7,500$). The training set consists of a large set of mock spectra of single stars and binaries synthesized based on the MIST stellar evolutionary model and ATLAS9 atmospheric model. Our model reaches a novel theoretic false positive rate by adding a proper penalty on the negative sample (e.g., 0.12\% and 0.16\% for the blue/red arm when the penalty parameter $Λ=16$). Tests show that the performance is as expected and favors FGK-type Main-sequence binaries with high mass ratio ($q \geq 0.7$) and large radial velocity separation ($Δv \geq 50\,\mathrm{km\,s^{-1}}$). Although the real false positive rate can not be estimated reliably, validating on eclipsing binaries identified from Kepler light curves indicates that our model predicts low binary probabilities at eclipsing phases (0, 0.5, and 1.0) as expected. The color-magnitude diagram also helps illustrate its feasibility and capability of identifying FGK MS binaries from spectra. We conclude that this model is reasonably reliable and can provide an automatic approach to identify SB2s with period $\lesssim 10$ days. This work yields a catalog of binary probabilities for over 5 million spectra of 1 million sources from the LAMOST medium-resolution survey (MRS), and a catalog of 2198 SB2 candidates whose physical properties will be analyzed in our following-up paper.

Optimal operation of a system of flood control reservoirs
Creators: name: Flavell, David Richard
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes a study of the application of linear programming, a mathematical optimization technique, to the problem of operating a system of flood control reservoirs in the most efficient way for maximum flood peak reduction. The reservoir system studied was one which is proposed for flood control in the Fraser River Basin and for which preliminary designs have been made. The proposed sites are in the headwater areas of the river basin, remote from the area to be protected. A channel routing method which was linear was required for use with the linear programming technique. A method was developed which was based on monoclinal wave theory. Several different cases were studied in which the reservoir capacities and combinations of reservoirs included in the system were varied. The results show the maximum regulation which is available from each combination of reservoirs and identify the minimum storage capacities required at each site. Application of the technique in planning studies and in real-time reservoir operation is discussed.
Differential rotation in fully convective stars

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Under the assumption of thermal wind balance and effective entropy mixing in constant rotation surfaces, the isorotational contours of the solar convective zone may be reproduced with great fidelity. Even at this early stage of development, this helioseismology fit may be used to put a lower bound on the midlatitude {\em radial} solar entropy gradient, which in good accord with standard mixing length theory. In this paper, we generalize this solar calculation to fully convective stars (and potentially planets), retaining the assumptions of thermal wind balance and effective entropy mixing in isorotational surfaces. It is found that each isorotation contour is of the form $R^2 = A+BΦ(r)$, where $R$ is the radius from the rotation axis, $Φ(r)$ is the (assumed spherical) gravitational potential, and $A$ and $B$ are constant along the contour. This result is applied to simple models of fully convective stars. Both solar-like surface rotation profiles (angular velocity decreasing toward the poles) as well as "antisolar" profiles (angular velocity increasing toward the poles) are modeled; the latter bear some suggestive resemblance to numerical simulations. We also perform exploratory studies of zonal surface flows similar to those seen in Jupiter and Saturn. In addition to providing a practical framework for understanding the results of large scale numerical simulations, our findings may also prove useful in dynamical calculations for which a simple but viable model for the background rotation profile in a convecting fluid is needed. Finally, our work bears directly on an important goal of the CoRoT program: to elucidate the internal structure of rotating, convecting stars.

An evaluation study of a parental alienation online support group
Creators: name: Toh, JW
Publisher: name: University Of Tasmania
Year: 2023

description: The Eeny Meeny Miney Mo (EMMM) Foundation founded an online support group for individuals impacted by parental alienation. The current mixed-methods study aimed to evaluate the efficacy of the online support group in supporting its members. To achieve this, an online support group moderator participated in a semi-structured interview. Seventeen male and 23 female online support group members completed the Group Climate questionnaire, Depression Anxiety Stress Scale -21 item (DASS-21), Stress Appraisal Measure (SAM) and Brief COPE (BC) Questionnaire at baseline (t1) and 3-month follow-up (t2). Participants' SAM Challenge, BC Active Coping, Emotional Support, Informational Support, and Planning scores significantly reduced over a 3-month period. However, DASS-21 scores did not significantly change between t\\(_1\\) and t\\(_2\\). Qualitative themes revealed that the support group experience was very positive, supportive, and comforting. Participants reported obtaining psychoeducation, support, information, validation, understanding, and hope. Participants recommended increased online security and provision of other types of support (i.e., clinical and legal). In short, this online support group is a good first port of call‚ÄövÑvp for individuals experiencing parental alienation. Future recommendations include training formal peer workers for this platform and identifying ways to promote this online support group to adults who were alienated as children.

title: Animal Nutritional Response to Sward Structure Under Short Duration Grazing Management
Creators: name: Olson, Kenneth C.
Publisher: name: Utah State University
Year: 1986

description: A ten-paddock short duration grazing cell was stocked with yearling heifers at a stocking rate of 0.7 ha per animal unit month and a stocking density of 0.14 ha per animal unit. A continuously-season- long-grazed (CSLG) pasture was used as a control. It was stocked at the same stocking rate, but at a stocking density of 1.4 ha per animal unit. Grazing periods in SDG paddocks were two or three days. Dietary quality was assessed by crude protein · content and in vitro digestibility of esophageal fistula estrusa samples. Three variables of ingestive behavior were measured, including ingestion rate, biting rate, and grazing time. Daily forage in take was estimated by multiplying ingestion rate by grazing time. Animals in CSLG gained significantly more weight in 1983, no statistical differences were detected in 1984, and, in 1985, animals gained more in SDG. No differences were detected in diet quality between SDG and CSLG throughout the study. No treatment differences were de tee ted in ingestive behavior variables in 1984, but ingestion rate was significatantly higher and grazing time significantly less in SDG during 1985. Differences in diet quality and ingestive behavior be tween SDG and CSLG at the beginning and end of the grazing season were evaluated for indications of possibly extending the season of nutritious forage. Such differences were few and inconsistent. Daily changes in diet quality and ingestive behavior during the grazing period within SDG paddocks were large. Diet quality declined significantly during the grazing period in all three years. Ingestive behavioral responses changed significantly, including declines in ingestion rate and increases in grazing time. Forage in take declined during the grazing period on a particular paddock. A model was developed that related behavioral responses to sward characteristics. Ingestion rate and grazing time were predicted from available biomass and herbage crude protein content. The model indicated that declines in biomass and herbage crude protein content translate into rapid declines in ingestion rate, and thus, forage in take. Based on the system studied, grazing periods in SDG paddocks should be two days or less to maintain high levels of livestock performance.

description: O presente estudo investiga como os professores de violino podem auxiliar os alunos a otimizarem o processo de memorização. Autores que investigaram esta temática destacaram a necessidade de um acesso eficaz às informações armazenadas, através da utilização de “pistas” (Retrieval Cues). No ensino do desporto essas mesmas “pistas” vêm sendo investigadas como forma de melhorar a comunicação, bem como promover uma aprendizagem mais significativa e que otimize a memorização. O objetivo deste estudo exploratório foi identificar pistas de ensino e o seu uso em aulas individuais de violino. Esse tópico de investigação surgiu a partir da minha experiência de sala de aula enquanto professora de violino, quando muitas vezes me questionei: “Porque preciso repetir tantas vezes determinadas instruções a alguns alunos? Porque é que às vezes os alunos não se lembram das informações na aula seguinte?” Essas e outras perguntas me levaram a uma observação detalhada sobre a interação entre professor e aluno num contexto de aula instrumental. Os resultados deste estudo enfatizam a importância e a necessidade de sistematizar o uso das pistas de ensino como ferramentas de aprendizagem.

title: A Market Analysis For Adult Outdoor Education In Five Western States
Creators: name: VanderZanden, Karla Joy
Publisher: name: Utah State University
Year: 1986

description: Organizations that offer Outdoor Education programs for adults are concerned with how to best attract people to their programs. Effective program design begins with a clear understanding of the people to be served. A marketing orientation--meeting the needs of participants--has begun to pervade non-profit management; specific information on the adult market for Outdoor Education remains limited. The purpose of this study was to identify and characterize segments based upon the benefits people seek from such an experience. Secondly, this analysis describes current programs 1n a five state region and identifies discrepancies between available and needed services. A mail survey of past participants of three residential programs (Audubon Camp of the West, National Wildlife Federation Summits and Teton Science School Seminars) was conducted in 1984. Participants were asked their reasons for attendance and their preferences for location, topic, accommodations and other program features. Demographic background such as age, sex, and income, was recorded. Thirty Outdoor Education organizations reported on their existing programs. The proposed method of segmentation--cluster analysis--failed to yield identifiable market segments using the forty three benefit variables selected from similar studies 1n outdoor recreation. Subsequent work in this study was devoted to testing alternative means of segmentation in order to identify a restricted list of variables capable of differentiating the sample public, somewhat specialized at the outset by virtue of past participation 1n Outdoor Education programs. Vacation-oriented and development-oriented segments were shown to significantly differ and the preferences of each described. Each organization appears to be serving slightly different types of people, with the clientele varying in the degree of comfort desired, concern for serious study and cost-consciousness. The overall market for adult Outdoor Education is primarily motivated by a desire to study and be close to nature. Social aspects, quest for knowledge and stimulation, and enjoyment of quiet beauty were also important considerations. Existing services and facilities 10 the five state region match expectations of participants with the exception of accommodations and meals provided. Many organizations continue to program for young adults even though the dominant age group is twenty-six to fifty-five years old with characteristic needs and interests. This market study and literature review form the bas is for recommending improvements in adult programming. A marketing point of view should enable Outdoor Educators to develop learning opportunities in the outdoor classroom that are not only inspirational, but attractive, convenient and affordable for selected target markets.

description: O trabalho proposto, que resultará em Tese de Doutoramento, compreende o estudo da dimensão da dramaturgia na dança contemporânea com foco na realidade da copresença em cena da ação da palavra e da ação física do corpo em movimento. O corpus é composto por um total de seis trabalhos coreográficos realizados em processo de colaboração artística de Rui Horta com o dramaturgo Tiago Rodrigues (Portugal) e de Lia Rodrigues com Silvia Soter (Brasil). De um conjunto de práticas artísticas e performances que dilatam a perceção de dança, e a par com elementos autónomos entre si, como: corpo em movimento, coreografia, som, figurinos, cenário; surgem a palavra e o texto, não só como recursos em cena, mas também de orientação dos processos de criação artística. Os exemplos específicos que se constituem como espaço motivador e propício para a construção de novos saberes e discursos são pensados através da teatralidade e da performatividade, investindo-se em ambos como recursos conceptuais vantajosos à operação das práticas cénicas contemporâneas. Pretende-se perceber como chegamos, na dança, à experiência da materialidade das palavras e a estas como acontecimento, ação articulada à fisicalidade e um modo de pensar e agir do sujeito em cena.

Evidences of the supercritical disc funnel radiation in X-ray spectra of SS 433

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We have analysed the XMM-Newton spectra of SS 433 using a standard model of adiabatically and radiatively cooling X-ray jets. The multi-temperature thermal jet model reproduces well the strongest observed emission line fluxes. The thermal model alone can not reproduce the continuum radiation in the XMM spectral range, the fluorescent iron line and some broad spectral features. Using the thermal jet-plus-reflection model, we find a notable contribution of ionized reflection to the spectrum in the energy range from ~3 to 12 keV. The reflecting surface is highly ionized (xi ~300), the illuminating radiation spectrum is flat and probably strongly absorbed. We conclude that the reflected spectrum is an evidence of the supercritical disc funnel, where the illuminating radiation comes from deeper funnel regions, to be further reflected in the outer visible funnel walls (r >~2*10^11 cm). We have not found any evidences of reflection in the soft 0.8-2 keV energy range, instead, a soft excess is detected, that does not depend on the thermal jet model details. This soft component might prove to be the direct radiation of the visible funnel wall. It is represented here either as black body radiation with the temperature of ~0.1 keV and luminosity of L_bb ~3*10^37 erg/s, or with a multicolour funnel (MCF) model. The soft spectral component has about the same parameters as those found in ULXs.

description: O folclore em Portugal representa uma atividade relevante no que toca às artes performativas de carácter tradicional. É reconhecido o esforço dos grupos folclóricos para manter a genuinidade das suas performances. No entanto, são evidentes as mudanças sociais e culturais ocorridas durante a evolução de folclore, resultando num progressivo distanciamento entre os agentes que representam o estilo e as tradições musicais e culturais que pretendem representar. Em todos os elementos performativos é possível encontrar marcas do tempo que (des)caracterizam o estilo folclórico. Quanto ao canto é também possível levantar questões. Canta-se hoje da mesma forma que se cantava no passado? Quais as características vocais representativas desta região? O que mudou? O presente estudo pretende descrever perceções sobre as práticas vocais das cantadeiras de folclore da região do Alto Minho. Através de entrevistas a elementos de grupos folclóricos de Viana do Castelo, verificou-se que as características típicas do cantar minhoto incluem: tessitura vocal aguda; registo de peito associado a “voz cheia”, com nível não-excessivo de esforço; timbre típico de “voz fina”; boa inteligibilidade; e sotaque da região. Os testemunhos apontam ainda para modificações acentuadas nas formas de aprendizagem e comportamentos sociais associados a esta prática vocal ao longo das últimas décadas.

description: This work summarises the results of a comparison organized by EURADOS focused on the usage of the ICRP Reference Computational Phantoms. This activity aimed to provide training for the implementation of voxel phantoms in Monte Carlo radiation transport codes and the calculation of the dose equivalent in organs and the effective dose. This particular case describes a scenario of immersion in a 16N beta source distributed in the air of a room with concrete walls where the phantom is located. Seven participants took part in the comparison of results using GEANT4, TRIPOLI-4 and MCNP family codes, and there was detected a general problem when calculating the dose to skeletal tissue and the remainder tissue. After a process of feedback with the participants the errors were corrected and the final results reached an agreement of +/-5%.

As interferências da performance no processo de composição musical de adolescentes no contexto escolar

Publisher: name: Post-ip: Revista do Fórum Internacional de Estudos em Música e Dança
Year: 2019

description: Este estudo preliminar possui como objetivo geral investigar como a performance do corpo pode interferir no processo de composição musical de adolescentes no contexto escolar. O conceito de composição musical é abordado como uma atividade pedagógica da aula de música (Maffioletti 2005). Este trabalho envolve duas concepções de performance: a primeira está relacionada ao ato de tocar em grupo, ou seja, a apresentação da música; a segunda concepção está relacionada às ações corporais envolvidas em todo o processo de composição, desde as primeiras organizações até o ato de apresentação. O interesse por este tema de pesquisa surgiu a partir dos estudos sobre a performance e a educação (Pineau 2013) em conjunto com o desejo de pesquisar a relação existente entre o adolescente, a composição musical e a educação básica. A metodologia da pesquisa tem uma abordagem qualitativa, mesclando as concepções de professorpesquisador, a etnografia da performance e o método de grupo de discussão. A coleta de dados foi realizada no período letivo e registrada através de gravação de áudio e vídeo em uma escola de ensino fundamental. A análise dos resultados será baseada nos estudos sobre performance e educação.

De sinal sonoro a marco sonoro: a recontextualização do berrante no Brasil e sua presença na música raiz do centro-sul brasileiro

description: Presente na história do tropeirismo brasileiro, o berrante é um instrumento feito de chifre de boi que, até à década de 1980, tinha como objetivo agrupar a boiada transportada pelos peões e estabelecer a comunicação entre estes. De acordo com a perspectiva de análise proposta por Murray Schafer, este instrumento constituía-se num importante sinal sonoro presente na paisagem sonora do Brasil rural. O desenvolvimento das tecnologias associadas ao trabalho no campo e ao transporte do gado promoveu a migração do berrante do contexto de trabalho para o contexto da música sendo resssignificado e transformado numa importante marca sonora associada a categorias veicularmente designadas como música raiz (aqui se incluem os segmentos música caipira e/ou sertaneja). Procuro apresentar, a partir da proposta de Murray Schafer e Barry Truax, uma análise do berrante no panorama da paisagem sonora rural brasileira e analisar a dinâmica de recontextualização deste no processo de migração de seu estatuto de instrumento de trabalho para um outro constituinte e identificador de um repertório musical. O conceito de paisagem cantada é adotado como principal ferramenta de análise uma vez que no romance – gênero cantado e central da música raiz - a poética-narrativa atua como testemunha da história do universo designado por caipira.

description: We present a search for CO(3-2) emission in SDF-26821, a BzK-selected star-forming galaxy (sBzK) at z = 2.044, using the 45-m telescope of the Nobeyama Radio Observatory and the Nobeyama Millimeter Array. We do not detect significant emission and derive 2 σlimits: the CO luminosity of L'CO < 3.1 x 10^10 K km s^{-1} pc^{-2}, the ratio of far-infrared luminosity to CO luminosity of L_FIR/L'CO > 57 Lsun (K km s^{-1} pc^{-2})^{-1}, and the molecular gas mass of M_H2 < 2.5 x 10^10 Msun, assuming a velocity width of 200 km s^{-1} and a CO-to-H2 conversion factor of alpha_CO=0.8 Msun (K km s^{-1} pc^{-2})^{-1}. The ratio of L_FIR/L'CO, a measure of star formation efficiency (SFE), is comparable to or higher than the two z ~ 1.5 sBzKs detected in CO(2-1) previously, suggesting that sBzKs can have a wide range of SFEs. Comparisons of far-infrared luminosity, gas mass, and stellar mass among the sBzKs suggest that SDF-26821 is at an earlier stage of forming stars with a similar SFE and/or more efficiently forming stars than the two z ~ 1.5 sBzKs. The higher SFEs and specific star formation rates of the sBzKs compared to local spirals are indicative of the difference in star formation modes between these systems, suggesting that sBzKs are not just scaled-up versions of local spirals.

description: An intercomparison exercise is described that examines Monte Carlo modelling of anthropomorphic voxel phantoms in an idealized ground-contamination photon exposure scenario. Thirteen participants calculated and submitted organ and effective dose rates for comparison against a set of verified reference solutions. The effective dose rates are shown to agree with the reference value to within reasonable statistical uncertainties in five of the cases, though in only one of those was similar agreement also demonstrated in the evaluation of all requested organ dose rates. Orders-of-magnitude differences in doses are seen for some of the other participants, both internally within their own dataset and also relative to the reference solutions. Following limited feedback and suggestions from the organizer, up to two sets of revised solutions were resubmitted by some of the participants; these generally exhibited improved agreement, though not always. The overall observations and conclusions from this intercomparison exercise are summarized and discussed.

description: In this paper we study the Landau levels in the non-relativistic dynamics of a neutral particle which possesses a permanent magnetic dipole moment interacting with an external electric field in the curved spacetime background with the presence or absence of a torsion field. The eigenfunction and eigenvalues of Hamiltonian are obtained. We show that the presence of the topological defect breaks the infinite degeneracy of the Landau levels arising in this system. We also apply a duality transformation to discuss this same quantization for a dynamics of a neutral particle with a permanent electric dipole moment.
