Year: 2020
Subjects: subject: Konferenzschrift
subject: 510

description: Continuing the tradition initiated in the MFO workshops held in 2014 and 2017, this workshop was dedicated to the newest developments in real algebraic geometry and polynomial optimization, with a particular emphasis on free non-commutative real algebraic geometry and hyperbolic programming. A particular effort was invested in exploring the interrelations with free probability. This established an interesting dialogue between researchers working in real algebraic geometry and those working in free probability, from which emerged new exciting and promising synergies.

description: Comet 17P/Holmes was observed for linear polarisation using the optical polarimeter mounted on the 1.2m telescope atop Gurushikhar peak near Mt. Abu during the period November-December 2007. Observations were conducted through the IHW narrow band (continuum) filters. During the observing run the phase angle was near $13^{\circ}$ at which the comet showed negative polarisation. On the basis of the observed polarisation data we find comet 17P/Holmes to be a typical comet with usual dust characteristics. We note that radial rate of change of brightness in coma in red band is higher than that in blue band; it has decreased by a factor of 3.6 and 2.5 respectively in red and blue bands during the November - December run, indicating relative increase in the abundance of smaller dust particles out ward. Radial brightness variation seen near the nucleus on November 6 is indicative of the presence of a blob or shocked region beyond 10" from the nucleus which has gradually smoothened by December 13. The brightness distribution is found steeper during November 5-7 as compared to on December 13.

description: Local phase transition from ferromagnetic to paramagnetic state in the region of the ballistic Ni nanocontacts (NCs) has been experimentally observed. We found that contact size reduction leads to an increase in the bias voltage at which the local phase transition occurs. Presented theoretical interpretation of this phenomena takes into the account the specificity of the local heating of the ballistic NC and describes the electron's energy relaxation dependences on the applied voltage. The experimental data are in good qualitative and quantitative agreement with the theory proposed.

description: Die vorliegende Arbeit widmet sich einem wissenschaftlich noch weitgehend unerschlossenen Gegenstand: dem deutschen Radio-Feature. Meine These lautet, dass innerhalb des deutschen Features eine bislang wenig beachtete Tradition des Erzählens existiert, die sich durch ein eigenes, für die Literaturwissenschaft hochinteressantes, Erzählverfahren auszeichnet. Die Besonderheit dieses Erzählverfahrens liegt in der radikalen Umsetzung von VIELSTIMMIGKEIT. Im Gegensatz zum Roman-Autor greift der Feature-Autor unmittelbar auf dokumentarisches Material, den so genannten „O-Ton“, zurück. Er arbeitet mit „fremden Stimmen“ und praktiziert so, mit den Worten Michail Bachtins, ein POLYPHONES Erzählen. Dieses Verfahren ist deshalb attraktiv, weil es den Erzählvorgang zum interaktiven Abenteuer werden lässt und es dem Autor ermöglicht, die Grenzen des eigenen Erfahrungshorizontes und der eigenen sprachlichen Ausdrucksmöglichkeiten zu überschreiten. Gleichzeitig wirft eine polyphone Ästhetik jedoch die ethische Frage nach einem verantwortungsbewussten Umgang mit den geliehenen Stimmen auf. Beispielhaft vorgestellt wird das polyphone Erzählverfahren an drei ausgewählten Features: Ernst Schnabels „Der 29. Januar 1947“ (1947), Peter Leonhard Brauns „8.15h OP III Hüftplastik“ (1970) und Michael Lisseks „Zwettls Traum? Die Nibelungenfragmente der Frau Dr. Ziegler. Oder: Sehen sie nichts?“ (2004).

description: Neural interfaces read the activity of biological neurons to help advance the neurosciences and offer treatment options for severe neurological diseases. The total number of neurons that are now being recorded using multi-electrode interfaces is doubling roughly every 4-6 years \cite{Stevenson2011}. However, processing this exponentially-growing data in real-time under strict power-constraints puts an exorbitant amount of pressure on both compute and storage within traditional neural recording systems. Existing systems deploy various accelerators for better performance-per-watt while also integrating NVMs for data querying and better treatment decisions. These accelerators have direct access to a limited amount of fast SRAM-based memory that is unable to manage the growing data rates. Swapping to the NVM becomes inevitable; however, naive approaches are unable to complete during the refractory period of a neuron -- i.e., a few milliseconds -- which disrupts timely disease treatment. We propose co-designing accelerators and storage, with swapping as a primary design goal, using theoretical and practical models of compute and storage respectively to overcome these limitations.

Geometric Structures in Group Theory (hybrid meeting)

Publisher: name: Zürich : EMS Publ. House
Year: 2020
Subjects: subject: Konferenzschrift
subject: 510

description: The conference focused on the use of geometric methods to study infinite groups and the interplay of group theory with other areas. One of the central techniques in geometric group theory is to study infinite discrete groups by their actions on nice, suitable spaces. These spaces often carry an interesting large-scale geometry, such as non-positive curvature or hyperbolicity in the sense of Gromov, or are equipped with rich geometric or combinatorial structure. From these actions one can investigate structural properties of the groups. This connection has become very prominent during the last years. In this context non-discrete topological groups, such as profinite groups or locally compact groups appear quite naturally. Likewise, analytic methods and operator theory play an increasing role in the area.

description: Spectral properties of 1-D Schrödinger operators $\mathrm{H}_{X,α}:=-\frac{\mathrm{d}^2}{\mathrm{d} x^2} + \sum_{x_{n}\in X}α_nδ(x-x_n)$ with local point interactions on a discrete set $X=\{x_n\}_{n=1}^\infty$ are well studied when $d_*:=\inf_{n,k\in\N}|x_n-x_k|>0$. Our paper is devoted to the case $d_*=0$. We consider $\mathrm{H}_{X,α}$ in the framework of extension theory of symmetric operators by applying the technique of boundary triplets and the corresponding Weyl functions. We show that the spectral properties of $\mathrm{H}_{X,α}$ like self-adjointness, discreteness, and lower semiboundedness correlate with the corresponding spectral properties of certain classes of Jacobi matrices. Based on this connection, we obtain necessary and sufficient conditions for the operators $\mathrm{H}_{X,α}$ to be self-adjoint, lower-semibounded, and discrete in the case $d_*=0$. The operators with $δ'$-type interactions are investigated too. The obtained results demonstrate that in the case $d_*=0$, as distinguished from the case $d_*>0$, the spectral properties of the operators with $δ$ and $δ'$-type interactions are substantially different.

description: We use transfer-matrix and finite-size scaling methods to investigate the location and properties of the multicritical point of two-dimensional Ising spin glasses on square, triangular and honeycomb lattices, with both binary and Gaussian disorder distributions. For square and triangular lattices with binary disorder, the estimated position of the multicritical point is in numerical agreement with recent conjectures regarding its exact location. For the remaining four cases, our results indicate disagreement with the respective versions of the conjecture, though by very small amounts, never exceeding 0.2%. Our results for: (i) the correlation-length exponent $ν$ governing the ferro-paramagnetic transition; (ii) the critical domain-wall energy amplitude $η$; (iii) the conformal anomaly $c$; (iv) the finite-size susceptibility exponent $γ/ν$; and (v) the set of multifractal exponents $\{η_k \}$ associated to the moments of the probability distribution of spin-spin correlation functions at the multicritical point, are consistent with universality as regards lattice structure and disorder distribution, and in good agreement with existing estimates.

Evidence of grain growth in the disk of the bipolar proto-planetary nebula M 1--92

description: We investigate the dust size and dust shell structure of the bipolar proto-planetary nebula M 1--92 by means of radiative transfer modeling. Our models consists of a disk and bipolar lobes that are surrounded by an AGB shell, each component having different dust characteristics. The upper limit of the grain size $a_\mathrm{max}$ in the lobes is estimated to be $0.5 μ$m from the polarization value in the bipolar lobe. The $a_\mathrm{max}$ value of the disk is constrained with the disk mass (0.2 $M_{\sun}$), which was estimated from a previous CO emission line observation. We find a good model with $a_\mathrm{max}=1000.0 μ$m, which provides an approximated disk mass of 0.15 $M_{\sun}$. Even taking into account uncertainties such as the gas-to-dust mass ratio, a significantly larger dust of $a_\mathrm{max}>100.0 μ$m, comparing to the dust in the lobe, is expected. We also estimated the disk inner radius, the disk outer radius, and the envelope mass to be 30 $R_\star$(=9 AU), 4500 AU, and 4 $M_{\sun}$, respectively, where $v_\mathrm{exp}$ is the expansion velocity. If the dust existing in the lobes in large separations from the central star undergoes little dust processing, the dust sizes preserves the ones in the dust formation. Submicron-sized grains are found in many objects besides M 1--92, suggesting that the size does not depend much on the object properties, such as initial mass of the central star and chemical composition of the stellar system. On the other hand, the grain sizes in the disk do. Evidence of large grains has been reported in many bipolar PPNs, including M 1--92. This result suggests that disks play an important role in grain growth.

description: The focus of the conference were recent interactions between model theory, group theory and combinatorics in finite geometries. In some cases, in particular in non-archimedean geometry or combinatorics in finite geometries, model theory appeared as tool. In other cases, like in ergodic theory and dynamics or in the theory of stable groups and more general neo-stable algebraic structures like valued fields, the focus was on model theoretic questions and classification results for such structures. In this way, the conference presented the broad range of topics of modern model theory.
The Hamiltonian description of incompressible fluid ellipsoids

description: We construct the noncanonical Poisson bracket associated with the phase space of first order moments of the velocity field and quadratic moments of the density of a fluid with a free- boundary, constrained by the condition of incompressibility. Two methods are used to obtain the bracket, both based on Dirac's procedure for incorporating constraints. First, the Poisson bracket of moments of the unconstrained Euler equations is used to construct a Dirac bracket, with Casimir invariants corresponding to volume preservation and incompressibility. Second, the Dirac procedure is applied directly to the continuum, noncanonical Poisson bracket that describes the compressible Euler equations, and the moment reduction is applied to this bracket. When the Hamiltonian can be expressed exactly in terms of these moments, a closure is achieved and the resulting finite-dimensional Hamiltonian system provides exact solutions of Euler's equations. This is shown to be the case for the classical, incompressible Riemann ellipsoids, which have velocities that vary linearly with position and have constant density within an ellipsoidal boundary. The incompressible, noncanonical Poisson bracket differs from its counterpart for the compressible case in that it is not of Lie-Poisson form.

description: The electron localization function ELF, which is crafted to reveal chemical bonds and their properties, has been generalized to the time-dependent regime. This allows the time-resolved visualization of the formation, modulation and breaking of bonds and gives thus insight into the dynamics of excited electrons. This has been illustrated by the pi–pi* transition of ethyne induced by a laser field, and by the destruction of bonds and the formation of lone-pairs in a scattering process of a proton with ethene. In the second part, an optimal control algorithm is used to determine an optimized laser pulse of a HOMO–LUMO transition of the diatomic molecule lithium fluoride.

This property was previously established for n < 10 in arXiv:0808.0491. We derive an explicit representation of these superamplitudes in terms of dual conformal cross-ratios. We also show that all the 1-loop `box coefficients' obtained from maximal cuts of N^kMHV n-point functions are covariant under dual conformal transformations.

Statistical watthour meter operating by polarity-coincidence correlation
Creators: name: Warman, Lloyd Alfred
Publisher: name: University of British Columbia
Year: 2011

description: A digital statistical watthour meter which operates by polarity-coincidence correlation is proposed. The output represents a continuously 'up-dated', time-multiplied estimate of the current and voltage cross-correlation function for zero delay. In previous correlators of this type, bounded uniformly-distributed random noise has been added to each input before clipping to linearize the input/output correlation function relationship. In the work reported here, the noise sources have been replaced by deterministic triangular wave generators. These have the advantage of being much simpler to construct and of enabling the statistical watthour meter to produce an acceptable estimate of the energy (for certain types of inputs) more quickly than with the former type of auxiliary function generator. An attempt has been made to predict the performance of the device using deterministic auxiliary functions by means of both analogue and digital computer simulations„ A prototype has also been constructed and tested with d-c and a-c inputs. The results of the simulations and prototype tests suggest that, if the meter electronics were refined and constructed for the most part as an integrated circuit, the statistical watthour meter could become a practical energy-measuring device in domestic, industrial and laboratory applications.

Resultate sind, daß die überwiegend konstruktivistische erkenntnistheoretische Haltung der drei Autoren sich nur bedingt mit systemtheoretischen Argumenten rechtfertigen läßt, und daß die zugrundegelegte Theorie selbstreferentieller Systeme generell noch nicht den Stand erreicht hat, auf dem sich zuverlässig Schlüsse ziehen lassen.

description: We present comprehensive results on the edge-mode velocities in a quantum Hall droplet with realistic interaction and confinement at various filling fractions. We demonstrate that the charge-mode velocity scales roughly with the valence Landau level filling fraction and the Coulomb energy in the corresponding Landau level. At Landau level filling fraction nu = 5/2, the stark difference between the bosonic charge-mode velocity and the fermionic neutral-mode velocity can manifest itself in the thermal smearing of the non-Abelian quasiparticle interference. We estimate the dependence of the coherence temperature on the confining potential strength, which may be tunable experimentally to enhance the non-Abelian state.

description: The Oberwolfach conference "Topologie" is one of only a few opportunities for researchers from many different areas in algebraic and geometric topology to meet and exchange ideas. On this occasion, because of the Corona pandemic, only about 20 participants attended in person, but another $\sim$ 25 attended online. Speakers were selected from both groups. A topic of special interest emphasized at the workshop was the rational homotopy theory of embedding spaces and relations to graph complexes and formality. Two 50 minute lectures on this theme were given by Thomas Willwacher, and one by Victor Turchin. The rest of the program covered a wide range of topics, among them: homotopy properties of diffeomorphism groups of high dimensional manifolds, advances in the classification of high-dimensional highly connected smooth manifolds, parametrized algebraic surgery in relation to hermitian algebraic K-theory, other advances in and geometric applications of algebraic K-theory, stable homotopy interpretation of link invariants, geometry of surface bundles and cohomology of mapping class groups, boundary concepts in geometric group theory, and Koszul duality for operads.

description: [Abridged] We present reliable multiwavelength identifications and high-quality photometric redshifts for the 462 X-ray sources in the ~2 Ms Chandra Deep Field-South. Source identifications are carried out using deep optical-to-radio multiwavelength catalogs, and are then combined to create lists of primary and secondary counterparts for the X-ray sources. We identified reliable counterparts for 446 (96.5%) of the X-ray sources, with an expected false-match probability of ~6.2%. A likelihood-ratio method is used for source matching, which effectively reduces the false-match probability at faint magnitudes compared to a simple error-circle matching method. We construct a master photometric catalog for the identified X-ray sources including up to 42 bands of UV-to-infrared data, and then calculate their photometric redshifts (photo-z's). The reliability of the photo-z's is evaluated using the subsample of 220 sources with secure spectroscopic redshifts. We achieve an accuracy of ~1% [|Delta z|/(1+z)] and an outlier fraction of ~1.4% for sources with spectroscopic redshifts. We performed blind tests to derive a more realistic estimate of the photo-z quality for sources without spectroscopic redshifts. We expect there are ~9% outliers for the relatively brighter sources (R<26), and the outlier fraction will increase to ~15-25% for the fainter sources (R>26). The typical photo-z accuracy is ~6-7%. The outlier fraction and photo-z accuracy do not appear to have a redshift dependence (for z~0-4). These photo-z's appear to be the best obtained so far for faint X-ray sources, and they have been significantly (>50%) improved compared to previous estimates of the photo-z's for the X-ray sources in the ~2 Ms Chandra Deep Field-North and ~1 Ms Chandra Deep Field-South.

Creators: name: Saif, Abdullah Omar

Year: 2021

description: It is widely acknowledged that access to health services and social supports is one of the determinants of a newcomer population's health status. It has been observed that research studies typically focus on investigating the experiences of immigrants and refugees. Experiences of other sub-groups of newcomers, such as academic sojourners, have remained overlooked and warrant attention from researchers. Using an interpretive phenomenological approach, the aim of my research was to investigate the experiences of international graduate student parents in accessing child health services and social supports. I examined perceived barriers and facilitators when accessing these services in St. John’s, Newfoundland and Labrador (NL). Through eight semi-structured interviews with these international graduate students, I found that key barriers in accessing services and support were the length of wait time, and participants’ negative experiences in navigating the healthcare system. Additionally, language barriers, participants’ limited interactions with the local population, lack of affordable daycare, and difficulties when it came to obtaining accurate healthcare information, added layers of complexity to their experience when accessing healthcare services. Factors that can facilitate access include professionalism of healthcare workers, child-friendly arrangements in patient waiting areas, and cultural sensitivity in healthcare delivery. These findings enhance our understanding of academic sojourners' access to child health services and social supports. They can also inform health promotion programs and activities targeted toward improving access to child health services and social supports for families of international students in Newfoundland and Labrador.
The design of a medium-scale hybrid interface
Creators: name: Marston, Glendon Peter
Publisher: name: University of British Columbia
Year: 2011

description: The most generally useful combination of analog and digital equipment possible is a hybrid installation which includes a general purpose digital computer and a general purpose analog computer, with a flexible interface between the two machines. This thesis contains a detailed description of a hybrid interface designed to link a DEC PDP-9 digital computer to an EAI Pace 231R-V analog computer and other equipment. Double buffering is provided on digital output channels from the PDP-9, including those servicing digital-to-analog (D/A) converters, loading from buffer registers to output registers can be commanded from either the analog or the digital side of the interface. A sixteen channel multiplexer with a settling time of less than two microseconds has been designed and is employed with a twelve bit analog-to-digital (A/D) converter for high speed data transfers. The digital voltmeter and signal selector in the analog computer are operated together to provide a low speed 540-point multiplexer-A/D converter. The signal selector, mode controls, and servo-set potentiometers of the analog computer can be operated on command from the PDP-9. Individual mode control of each of sixteen integrators is also provided.

Year: 2020
Subjects: subject: Konferenzschrift
subject: 510

description: This is the report of the Oberwolfach workshop Komplexe Analysis 2020. It was mainly devoted to the transcendental methods of complex algebraic geometry and featured eighteen talks about recent important developments in Hodge theory, moduli spaces, hyperbolicity, Fano varieties, algebraic foliations, algebraicity theorems for subvarieties and their applications to transcendence proofs for numbers. Two talks were more algebraic in nature and devoted to non-commutative deformations and syzygies of secant varieties.
Mixture model of open clusters in CMD
Creators: name: Li, Lu

Publisher: name: Zenodo
Year: 2021
Subjects: Open cluster, Mixture model

description: We developed a rigorous Bayesian frame that treats the open clusters (OC) in CMD as a mixture of members and field stars. The advanced statistics and comprehensive physical models make our method the state of the art of determining the basic properties (Age, Distance, [Fe/H], extinction AV) along with the slope of MF and the binary fraction of OCs in using photometric data of Gaia EDR3. We also accurately determine the binary fraction fb and γq for NGC3532 by using the mixture model method. For the first time, we unveil that the stars with smaller mass or in the inner region tend to have lower fb and a more positive value of γq due to the lack of low mass ratio binaries. It is strong evidence of the internal dynamics in a cluster.

description: LUTIs (Long Undecoded Transcript Isoforms) are 5′-extended and poorly translated mRNAs that can downregulate transcription from promoters more proximal to a gene’s coding sequence (CDS). In this protocol, polyA RNA is extracted from budding yeast cells undergoing highly synchronized meiosis. Using a combination of long-read direct RNA sequencing and transcript leader sequencing (TL-seq), meiosis-specific LUTIs are systematically identified. Following identification, TL-seq is used to quantify the abundance of both LUTI and the more canonical gene-proximal (PROX) transcripts.

description: Let $\bf M$ be a smooth compact oriented Riemannian manifold, and let $Δ_{\bf M}$ be the Laplace-Beltrami operator on ${\bf M}$. Say $0 \neq f \in \mathcal{S}(\RR^+)$, and that $f(0) = 0$. For $t > 0$, let $K_t(x,y)$ denote the kernel of $f(t^2 Δ_{\bf M})$. We show that $K_t$ is well-localized near the diagonal, in the sense that it satisfies estimates akin to those satisfied by the kernel of the convolution operator $f(t^2Δ)$ on $\RR^n$. We define continuous ${\cal S}$-wavelets on ${\bf M}$, in such a manner that $K_t(x,y)$ satisfies this definition, because of its localization near the diagonal. Continuous ${\cal S}$-wavelets on ${\bf M}$ are analogous to continuous wavelets on $\RR^n$ in $\mathcal{S}(\RR^n)$. In particular, we are able to characterize the H$\ddot{o}$lder continuous functions on ${\bf M}$ by the size of their continuous ${\mathcal{S}}-$wavelet transforms, for H$\ddot{o}$lder exponents strictly between 0 and 1. If $\bf M$ is the torus $\TT^2$ or the sphere $S^2$, and $f(s)=se^{-s}$ (the ``Mexican hat'' situation), we obtain two explicit approximate formulas for $K_t$, one to be used when $t$ is large, and one to be used when $t$ is small.

description: Because of the pandemia, the workshop on "Low-Dimensional Topology and Number Theory" could not be realized in the usual format or in the new hybrid format. Instead, a subgroup consisting of 6 participants used the week at the MFO mostly for informal discussions, collaborations and research in the topic of the workshop, including some online contacts to other participants who were not able to come to the MFO. At the institute talks were given by Campbell Wheeler on "WRT invariants & quantum modularity", Gregor Masbaum on "Generic skein modules", Gaëtan Borot on "Counting multicurves on surfaces with respect to hyperbolic vs. combinatorial geometry", Roland van der Veen on "1-cocycle invariants of knots", and by Michael Ontiveros on "From a triangulated lens space to a modular form".
EPS09 - a New Generation of NLO and LO Nuclear Parton Distribution Functions

description: We present a next-to-leading order (NLO) global DGLAP analysis of nuclear parton distribution functions (nPDFs) and their uncertainties. Carrying out an NLO nPDF analysis for the first time with three different types of experimental input -- deep inelastic $\ell$+A scattering, Drell-Yan dilepton production in p+$A$ collisions, and inclusive pion production in d+Au and p+p collisions at RHIC -- we find that these data can well be described in a conventional collinear factorization framework. Although the pion production has not been traditionally included in the global analyses, we find that the shape of the nuclear modification factor $R_{\rm dAu}$ of the pion $p_T$-spectrum at midrapidity retains sensitivity to the gluon distributions, providing evidence for shadowing and EMC-effect in the nuclear gluons. We use the Hessian method to quantify the nPDF uncertainties which originate from the uncertainties in the data. In this method the sensitivity of $χ^2$ to the variations of the fitting parameters is mapped out to orthogonal error sets which provide a user-friendly way to calculate how the nPDF uncertainties propagate to any factorizable nuclear cross-section. The obtained NLO and LO nPDFs and the corresponding error sets are collected in our new release called {\ttfamily EPS09}. These results should find applications in precision analyses of the signatures and properties of QCD matter at the LHC and RHIC.

Topological and Smooth Dynamics on Surfaces (individual research only)

Subjects: subject: Konferenzschrift

description: Because of the pandemia, the workshop on "Topological and Smooth Dynamics on Surfaces" could not be realized in the usual format or in the new hybrid format. Instead, a subgroup of 3 participants used the week mostly for informal discussions, collaborations and research in the topic of the workshop. Namely, a study of a parametric family of planar homeomorphisms was carried out by Boroński and Štimac. Recently a novel approach to the study of parametric families of disiaptive diffeomorphisms on surfaces was introduced by Crovisier and Pujals in their seminal paper [1], in which they initiate the study of the class of strongly dissipative diffeomorphisms. These maps are shown in [1] to be very close in a certain sense to 1-dimensional maps. In particular, Crovisier and Pujals showed that for any of them there exists a reduction to a 1-dimensional model, that consists of a metric tree and a continuous map on it that is semi-conjugate to the original diffeomorphism. The authors also showed that the class of strongly dissipative diffeomorphisms contains maps in the Hénon family, for an open set of parameters. The study carried out by Boroński and Štimac at MFO attempted on generalizing the aforementioned results to a new setting. Namely, a Crovisier-Pujals-like 1-dimensional model was constructed for a Lozi family of maps [3], within the Misiurewicz parameter set [4]. This model conjugates each Lozi map in the studied parameter set to the natural extension of a continuous map on a metric tree, thus extending the earlier result to the $C^{0}$ case, but also improving semi-conjugation to a conjugacy. Further results in this direction are expected to come in a timely fashion. The Ph.D. student Kilassa Kvaternik studied and presented the paper [2].
