The 12th International Conference of Students of Systematic Musicology (SysMus19)

At the 12th International Conference of Students of Systematic Musicology (SysMus19), students from all over the world came together to share and discuss their work spanning this interdisciplinary and diverse field. As a student-led conference, the SysMus series aims to provide a platform whereby early-stage researchers can hone their skills and gain experience in an open and friendly environment. Additionally, keynotes held by Dr. Klaus Frieler (Hochschule für Musik Franz Liszt, Weimar) and Dr. Helga de la Motte-Haber (Technische Universität Berlin), as well as workshops on different research tools and approaches, added to the depth and variety of the event. This report provides an overview of the conference and a summary of the work presented

Direct immunofluorescence is of limited utility in patients with low clinical suspicion for an oral autoimmune bullous disorder

ObjectivesOral autoimmune bullous disorders show clinical overlap with diseases such as lichen planus and others that may cause desquamative gingivitis. As direct immunofluorescence is expensive, we sought to determine if routine histology alone would be sufficient to distinguish between oral autoimmune bullous disorders and mimics.MethodsWe searched the records for patients with a suspected oral autoimmune bullous disorder who underwent biopsies for concurrent routine histologic evaluation and direct immunofluorescence and who had at least one followâ up visit. Cases were separated into high and low suspicion subgroups based on clinical findings.ResultsWithin 148 cases, the sensitivity of routine histology alone was 0.810, with a negative predictive value of 0.889. However, the specificity was 0.989 with a positive predictive value of 0.979. Of the high suspicion cases, 57 (47.1%) were found to be consistent with an oral autoimmune bullous disorder, with a total of 11 histologic false negatives. 8 cases, all in the high suspicion subgroup, showed indeterminate direct immunofluorescence results. There were no histologic false negatives or inconclusive direct immunofluorescence results in the low suspicion subgroup.ConclusionsIn patients with a low clinical suspicion for an oral autoimmune bullous disorder, it is reasonable and more costâ effective to evaluate the lesion with routine histology alone.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/153107/1/odi13159_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/153107/2/odi13159.pd

Two-photon spin injection in semiconductors

A comparison is made between the degree of spin polarization of electrons excited by one- and two-photon absorption of circularly polarized light in bulk zincblende semiconductors. Time- and polarization-resolved experiments in (001)-oriented GaAs reveal an initial degree of spin polarization of 49% for both one- and two-photon spin injection at wavelengths of 775 and 1550 nm, in agreement with theory. The macroscopic symmetry and microscopic theory for two-photon spin injection are reviewed, and the latter is generalized to account for spin-splitting of the bands. The degree of spin polarization of one- and two-photon optical orientation need not be equal, as shown by calculations of spectra for GaAs, InP, GaSb, InSb, and ZnSe using a 14x14 k.p Hamiltonian including remote band effects. By including the higher conduction bands in the calculation, cubic anisotropy and the role of allowed-allowed transitions can be investigated. The allowed-allowed transitions do not conserve angular momentum and can cause a high degree of spin polarization close to the band edge; a value of 78% is calculated in GaSb, but by varying the material parameters it could be as high as 100%. The selection rules for spin injection from allowed-allowed transitions are presented, and interband spin-orbit coupling is found to play an important role.Comment: 12 pages including 7 figure

Extracting surface representations from rim curves

LNCS v. 3852 is the conference proceedings of ACCV 2006In this paper, we design and implement a novel method for constructing a mixed triangle/quadrangle mesh from the 3D space curves (rims) estimated from the profiles of an object in an image sequence without knowing the original 3D topology of the object. To this aim, a contour data structure for representing visual hull, which is different from that for CT/MRI, is introduced. In this paper, we (1) solve the "branching structure" problem by introducing some additional "directed edge", and (2) extract a triangle/ quadrangle closed mesh from the contour structure with an algorithm based on dynamic programming. Both theoretical demonstration and real world results show that our proposed method has sufficient robustness with respect to the complex topology of the object, and the extracted mesh is of high quality. © Springer-Verlag Berlin Heidelberg 2006.postprintThe 7th Asian Conference on Computer Vision (ACCV 2006), Hyderabad, India, 13-16 January 2006.

Nomadism and movement as epistemologies of the contemporary world (El nomadismo y el movimiento como epistemologías del mundo contemporáneo)

In the same way that movement and nomadism as a lifestyles opposite to sedentism involve not only the abandonment of the idea of a permanent home, but also an active challenge or furtive avoidance of the state's sedentary authority, movement and nomadism as epistemologies confront the generally fixed order of languages, discourses and perspectives with which science tries to explain our social world. New ways of thinking about movement, subjectivities, groups and institutions emerge, in a world that is not only global, but real and virtual at the same time. In this special issue we have gathered the contributions that experiment and questioning static thinking

К ВОПРОСУ О РОЛИ СИМВОЛИЧЕСКОГО В ИДЕНТИФИКАЦИИ ЧЕЛОВЕКА ИНФОРМАЦИОННОГО/ЦИФРОВОГО ОБЩЕСТВА

The transformation of society during the transition to a new stage of civilizational development is accompanied by dichotomous phenomena. Against the background of globalization processes, a decrease in the role of the national, associated with numbers and the development of global network digital communications, there is a sharp increase in ethnic and religious factors, the actualization of historical symbols as elements of human identity and the collective identity of a nation or country. This phenomenon is considered from the standpoint of postmodernism, where the object of the past is simulated into the subjective perception of a simulacrum in the consciousness of a person in modern society. We criticize metamodernism, proving the symbolic nature of oscillation. The appeal to the past in modernity is nothing but the construction of traditions, rituals, customs in new conditions, under the influence of the present, that is, the simulation of current economic and political, socio-cultural processes. The formation of identity is considered both from the side of the external influence of the institutions of power and management and the elite, and from the side of adaptation of human consciousness that occurs under the influence of the transformations of society. Institutions of power and government contribute to the creation and dissemination of simulacra of historical, ethnic, religious constructs. This allows the upper strata of society to form the collective identity they require, to homogenize society, affirming a single symbolism, common values for all residents. A modern person, for the reasons considered in the article, strives for multiple identification, which is due to the desire to strengthen communication with a multitude of communities that are formed on the basis of a commonality of symbols, values, codes. Experiencing existential fear of a digital society, a person seeks shelter in the images of the past, in the simulation of the stasis of his contemporary society based on the symbols of history, religion, and ethnicity. The second reason is the desire to enter the largest number of communities, staying in which allows you to strengthen the quality and quantity of communications, increase the ability to adapt, and reduce the level of risk. The specific features of the younger generation Z are considered separately. Born with a “gadget in hand”, digital natives are initially adapted in a digital society, and therefore their perception is somewhat different than that of the older generation. The cited research data of the authors shows significant specific differences in the perception of the values of previous eras among the younger generation, which allows us to hope for a weakening of the tendencies for the formation of identity based on archaic symbols in the near future.Трансформация общества в процессе перехода на новую стадию цивилизационного развития сопровождается дихотомическими явлениями. На фоне глобализационных процессов, снижением роли национального, связанного в том чисел и с развитием глобальных сетевых цифровых коммуникаций наблюдается резкий рост этнического и религиозного факторов, актуализации исторических символов как элементов идентичности человека и коллективной идентичности нации, страны. Данное явление рассматривается с позиций постмодернизма, где объект прошлого симулируется в субъективное восприятие симулякра в сознании человека современного общества. Мы выступаем с критикой метамодернизма, доказывая символический характер осцилляции. Обращения к прошлому в современности не что иное, как конструирование традиций, ритуалов, обычаев в новых условиях, под воздействием настоящего, то есть симуляция актуальных экономико–политических, социокультурных актуальных процессов. Формирование идентичности рассмотрено как состороны внешнего влияния институтов власти и управления и элиты, так и со стороны адаптации сознания человека, происходящей под влиянием трансформаций общества. Институты власти и управления способствуют созданию и распространению симулякров исторических, этнических, религиозных конструктов. Это позволяет высшим слоям общества формировать требуемую им коллективную идентичность, гомогенизировать общество, утверждая единую символику, единые ценности для всех жителей. Современный человек, по причинам, рассматриваемых в статье, стремиться к множественной идентификации, что обусловлено стремлением к усилению коммуникаций с множеством сообществ, формирующихся на основе общности символов, ценностей, кодов. Испытывая экзистенциальный страх перед цифровым обществом, человек ищет укрытия в образах прошлого, в симуляции стазиса современного ему общества на основе символов истории, религии, этноса. Вторая причина – стремление к вхождению в наибольшее число сообществ, пребывание в которых позволяет усиливать качество и количество коммуникаций, повысить способность к адаптации, снизить уровень риска. Отдельно рассмотрены специфические особенности молодого поколения Z. Родившись с «гаджетом в руке» цифровые аборигены изначально адаптированы в цифровом обществе, а потому их восприятие не-сколько иное, чем у старшего поколения. Приведенные данные исследования авторов показывает существенные специфические отличия в восприятии ценностей предыдущих эпох у молодого поколения, что позволяет надеяться на ослабление тенденций формирования идентичности на основе архаичных символов в ближайшем будущем

Safe and complete contig assembly via omnitigs

Contig assembly is the first stage that most assemblers solve when reconstructing a genome from a set of reads. Its output consists of contigs -- a set of strings that are promised to appear in any genome that could have generated the reads. From the introduction of contigs 20 years ago, assemblers have tried to obtain longer and longer contigs, but the following question was never solved: given a genome graph $G$ (e.g. a de Bruijn, or a string graph), what are all the strings that can be safely reported from $G$ as contigs? In this paper we finally answer this question, and also give a polynomial time algorithm to find them. Our experiments show that these strings, which we call omnitigs, are 66% to 82% longer on average than the popular unitigs, and 29% of dbSNP locations have more neighbors in omnitigs than in unitigs.Comment: Full version of the paper in the proceedings of RECOMB 201

Improving teaching: Enhancing ways of being university teachers

My aim in this paper is to theorize my teaching in a course for experienced university teachers, in a context of increased attention to such courses. My focus in the course is transforming and enhancing ways of being university teachers, through integrating knowing, acting and being. In other words, epistemology is not seen as an end in itself, but rather it is in the service of ontology. In the paper, I explore and illustrate how this focus on ontology is enacted in the course

Analysis of vadose zone inhomogeneity toward distinguishing recharge rates: Solving the nonlinear interface problem with Newton method

Citation: Steward, D. R. (2016). Analysis of vadose zone inhomogeneity toward distinguishing recharge rates: Solving the nonlinear interface problem with Newton method. Water Resources Research, 52(11), 8756-8774. doi:10.1002/2016wr019222Recharge from surface to groundwater is an important component of the hydrological cycle, yet its rate is difficult to quantify. Percolation through two-dimensional circular inhomogeneities in the vadose zone is studied where one soil type is embedded within a uniform background, and nonlinear interface conditions in the quasilinear formulation are solved using Newton's method with the Analytic Element Method. This numerical laboratory identifies detectable variations in pathline and pressure head distributions that manifest due to a shift in recharge rate through in a heterogeneous media. Pathlines either diverge about or converge through coarser and finer grained materials with inverse patterns forming across lower and upper elevations; however, pathline geometry is not significantly altered by recharge. Analysis of pressure head in lower regions near groundwater identifies a new phenomenon: its distribution is not significantly impacted by an inhomogeneity soil type, nor by its placement nor by recharge rate. Another revelation is that pressure head for coarser grained inhomogeneities in upper regions is completely controlled by geometry and conductivity contrasts; a shift in recharge generates a difference Dp that becomes an additive constant with the same value throughout this region. In contrast, shifts in recharge for finer grained inhomogeneities reveal patterns with abrupt variations across their interfaces. Consequently, measurements aimed at detecting shifts in recharge in a heterogeneous vadose zone by deciphering the corresponding patterns of change in pressure head should focus on finer grained inclusions well above a groundwater table
