description: Integrable and non-integrable systems have very different transport properties. In this work, we highlight these differences for specific one dimensional models of interacting lattice fermions using numerical exact diagonalization. We calculate the finite temperature adiabatic stiffness (or Drude weight) and isothermal stiffness (or ``Meissner'' stiffness) in electrical and thermal transport and also compute the complete momentum and frequency dependent dynamical conductivities $σ(q,ω)$ and $κ(q,ω)$. The Meissner stiffness goes to zero rapidly with system size for both integrable and non-integrable systems. The Drude weight shows signs of diffusion in the non-integrable system and ballistic behavior in the integrable system. The dynamical conductivities are also consistent with ballistic and diffusive behavior in the integrable and non-integrable systems respectively.

description: We investigate the spectral properties of one-dimensional lattices with position-dependent hopping amplitudes and on-site potentials that are smooth bounded functions of position. We find an exact integral form for the density of states (DOS) in the limit of an infinite number of sites, which we derive using a mixed Bloch-Wannier basis consisting of piecewise Wannier functions. Next, we provide an exact solution for the inverse problem of constructing the position-dependence of hopping in a lattice model yielding a given DOS. We confirm analytic results by comparing them to numerics obtained by exact diagonalization for various incarnations of position-dependent hoppings and on-site potentials. Finally, we generalize the DOS integral form to multi-orbital tight-binding models with longer-range hoppings and in higher dimensions.

description: We calculate the two-point correlation function and magnetic susceptibility in the anisotropic 2D Ising model on a lattice with one infinite and the other finite dimension, along which periodic boundary conditions are imposed. Using exact expressions for a part of lattice form factors, we propose the formulas for arbitrary spin matrix elements, thus providing a possibility to compute all multipoint correlation functions in the anisotropic Ising model on cylindrical and toroidal lattices. The scaling limit of the corresponding expressions is also analyzed.

A structural investigation of the capsular antigens of two E. coli strains K26 and K49
Creators: name: Beynon, Linda M.
Publisher: name: University of British Columbia
Year: 2010

description: Diseases caused by encapsulated bacteria such as E. coli are among the most prevalent in the world. The polysaccharide capsule (K antigen) is an important factor in the virulence and pathogenicity of E. coli bacteria. Serological classification of these bacteria is also based mainly on the immunologically dominant capsular polysaccharide, due to its location at the bacterial cell surface. In order to understand the role played by the K antigens in bacterial infections, and the chemical basis of serological differentiation, the systematic structural investigation of all the capsular polysaccharides of E. coli (74 serotypes) is underway in this laboratory and others. Presented in this thesis are the structures of the K antigens of E. coli K26 and K49 serotypes. K26 capsular polysaccharide was studied using techniques such as methylation analysis, β-elimination, Smith degradation and partial hydrolysis. The oligosaccharides produced by the partial acid hydrolysis were analysed by g.c.-c.i.-m.s. To aid in the characterization of these oligosaccharides, a 'library' of relative retention times and c.i. mass spectra of authentic standards (di-, tri-, and tetra-saccharides) was prepared. The results from these analyses, together with data from n.m.r. spectroscopy of the native polysaccharide and derived oligosaccharides, allowed the following structure to be assigned to E. coli K26 polysaccharide. [Formula Omitted] E. coli K49 capsular antigen contains two amino acids, serine and threonine, amidically linked to the carboxyl group of glucuronic acid. Techniques used in the structural elucidation were raethylation analysis, acetolysis, amino acid analysis, HF hydrolysis, partial acid hydrolysis and Smith degradation. The oligosaccharides generated by the three latter methods were analysed by g.c.-c.i.-m.s. and n.m.r. spectroscopy. A bacteriophage-associated enzyme degradation of the K49 antigen yielded a product (P1) which consisted of a single repeating unit (see below). Results from the analyses of P1 and the chemically produced oligosaccharides were in agreement with the following assignment for the structure of the E. coli K49 capsular polysaccharide.

description: We relate previously defined quantum characteristic classes to Morse theoretic aspects of the Hofer length functional on $\ls$. As an application we prove a theorem which can be interpreted as stating that this functional behaves "virtually" as a perfect Morse-Bott functional with a flow. This can be applied to study topology and Hofer geometry of $ \text {Ham}(M, ω)$. We also use this to give a prediction for the index of some geodesics for this functional, which was recently partially verified by Yael Karshon and Jennifer Slimowitz.

description: Image relighting is attracting increasing interest due to its various applications. From a research perspective, image relighting can be exploited to conduct both image normalization for domain adaptation, and also for data augmentation. It also has multiple direct uses for photo montage and aesthetic enhancement. In this paper, we review the NTIRE 2021 depth guided image relighting challenge. We rely on the VIDIT dataset for each of our two challenge tracks, including depth information. The first track is on one-to-one relighting where the goal is to transform the illumination setup of an input image (color temperature and light source position) to the target illumination setup. In the second track, the any-to-any relighting challenge, the objective is to transform the illumination settings of the input image to match those of another guide image, similar to style transfer. In both tracks, participants were given depth information about the captured scenes. We had nearly 250 registered participants, leading to 18 confirmed team submissions in the final competition stage. The competitions, methods, and final results are presented in this paper.

description: An autonomous robot that acts in a goal-directed fashion requires a world model of the elements that are relevant to the robot's task. In real-world, dynamic environments, the world model has to be created and continually updated from uncertain sensor data. The symbols used in plan-based robot control have to be anchored to detected objects. Furthermore, robot perception is not only a bottom-up and passive process: Knowledge about the composition of compound objects can be used to recognize larger-scale structures from their parts. Knowledge about the spatial context of an object and about common relations to other objects can be exploited to improve the quality of the world model and can inform an active search for objects that are missing from the world model. This thesis makes several contributions to address these challenges: First, a model-based semantic mapping system is presented that recognizes larger-scale structures like furniture based on semantic descriptions in an ontology. Second, a context-aware anchoring process is presented that creates and maintains the links between object symbols and the sensor data corresponding to those objects while exploiting the geometric context of objects. Third, an active perception system is presented that actively searches for a required object while being guided by the robot's knowledge about the environment.

description: Power grids constitute an essential infrastructure providing and distributing electrical energy. The grid structure is currently subject to rapid changes due to the integration of renewable energy sources. In this development one is confronted with several challenges and opportunities as, for instance, the reduction of inertial masses in the system, the strongly increasing decentralisation of generators, and the fluctuating power feed-in by generators relying on renewable energy sources. In this thesis, models are studied that describe the non-linear power-grid dynamics in the presence of fluctuating power feed-in from renewable energy sources, primarily wind turbines. Realistic features of wind-power feed-in are captured by using real data measured at a research platform located in the North Sea. This approach is applied to test systems provided by the Institute of Electrical and Electronics Engineers (IEEE), in which one conventional generator is replaced by a wind turbine. It is found that so-called dead ends and other weakly coupled network parts are particularly prone to power fluctuations and perturbations. In contrast to previous studies, the often pronounced heterogeneities of the power grid elements are taken into account when solving the non-linear power-flow and swing equations. Also reactances between locations of power generation and power feed-in are considered, which causes the link topology in the power grid to correspond to a full graph, where all nodes are effectively connected. Both the grid heterogeneities and the additional generator reactances have a decisive impact on power grid stability. Some structures considered as particularly stable in simplified models are prone to perturbations when utilising the more realistic model and vice versa. By the analysis of various quantities characterising functional grid operation, it is shown that a reliable assessment of power grid stability requires the consideration of heterogeneities and generator reactances.

description: Studying the mechanisms may not require the use of 3D models directly, as we attempt to investigate its comprehensive study through a linear drawing of the mechanism. We can accurately ascribe the relationships between the various members of the mechanism, how they are connected to each other, what is their movement and how we can study every one of its sizes, angles, and velocities. This is being done adopting special systems. In this project, we will use the NX system, and particularly, the NX layout system, with which we can make two-dimensional designs, which will be provided with kinematic properties to thoroughly study the mechanism. After identifying its dimensions, we will proceed to the construction of the three-dimensional drawings. The application of the methodology will be carried out on a 4-cylinder crankshaft.

description: Electron impact ionization is an important phenomenon touching many areas of science, and much research has been done over the years on various aspects of this process. Efforts to establish the precise variation of ionization cross section with energy were initiated in the early 1950's; however, severe disagreements between experimental data concerning fine structure observed in the electron impact ionization efficiency curves were reported from laboratory to laboratory. The work in this thesis has been largely devoted to establishing the credibility of the method of electron impact ionization by monoenergetic electron beam in the study of such fine structure. The design and construction of an apparatus to study the ionization of atoms and molecules by an electron beam of narrow energy width are described, and preliminary data on krypton and argon near the ionization threshold energies discussed. A sound basis has been laid for further development in this field.

description: Introduction: While holmium laser enucleation of the prostate (HoLEP) is accepted as safe and efficient, a long learning curve is considered the main reason for its slow adoption in clinical practice. So far, no standardized and easy-to-use parameter has been implemented to measure surgical experience or efficiency which could be useful for training and quality control purposes. The aim of the present study was to evaluate the learning curves of 2 HoLEP beginners and to identify applicable efficiency outcome measures as well as potentially complicating factors in performing HoLEP. Patients and Methods: A total of 594 patients treated by HoLEP between September 2016 and May 2019 were enrolled. The procedures were initially performed by 1 HoLEP expert (reference surgeon); over time, 2 further surgeons were trained. Baseline characteristics, enucleation weight, morcellation and enucleation time, laser energy usage, and postoperative results were recorded prospectively. The learning curves of the 2 novices were analyzed and compared to the reference surgeon. Logistic regression analyses were performed to identify predictors for postoperative grade >= 2 complications. Results: Median enucleation ratio and complication rates did not significantly alter along the learning curves. Median enucleation speed and laser energy application of the 2 novices significantly improved with growing experience. Combining these variables, we introduced the "HoLEP efficiency score" (HES) which demonstrated the most appropriate value to reflect the surgical experience and efficiency. The median HES for the reference surgeon was 82.8 min kJ/g. For the 2 novices, a drop from 130 and 124.4 min kJ/g by -57 and -30%, respectively, was observed. Among several tested clinical parameters, the presence of prostate cancer (p = 0.047) and the surgical caseload (p < 0.001) influenced the HES. On multivariable logistic regression, American Society of Anesthesiologists score and prostate cancer were independent predictors for grade >= 2 complications (p = 0.002, odds ratio [OR] 2.042 and p = 0.038, OR 1.940). Conclusion: We introduce the HES as an objective and measurable tool to quantify surgical efficiency. In clinical practice, the HES may find application in training and quality control purposes as well as in comparing surgical modifications and hardware. Patients with prostate cancer seem to be more challenging cases and have a higher risk for complications, and may preferably be treated by experienced surgeons.
Narratívák temporális mintázata tinédzserkortól időskorig

description: Temporal patterns of narratives across the lifespan

Narrative is an important interactional speech communication form that each generation uses. Narrative production involves organizing and expressing a series of events and facts that were experienced by the speaker. Narrative as specific verbal behavior shares similarities with various styles of spontaneous speech; however, there are marked differences in several important ways like memory processes. There is a specific type of narratives when the speaker is asked to summarize a heard text immediately. The input is based on speech comprehension followed by the usual speech planning processes. Our research question is whether the temporal parameters of narratives show changes from teenagers to old speakers. 56 speakers (ages between 16 and 80 years) forming six age groups were randomly selected from two databases (BEA and TiniBEA) according to their ages. The length of the narratives, the number of words the narratives consisted of, the subjects’ speech tempi, relative frequency and durations of phrases, silent and filled pauses, as well as speaking fluency and individual differences were analyzed (using Praat software). Results showed large overlaps between data of the neighboring age groups. Significant differences could be proved between the three young and the three old groups in a number of temporal parameters, like durations of
phrases and pauses. Some of the measured data of the narratives analyzed reflect the dominant usage of either short-term or long-term memory that depends on age.

description: Conversation, turn-taking and discourse organization: new insights on the interface of phonetics and pragmatics in a Hungarian conversation. A pilot study


One of the most important way of language use is conversation (verbal interaction or spoken discourse). Phonetic details play crucial role in it, however, there are only a few research studies on phonetic aspects of Hungarian conversations and their connections with the pragmatic dimension. The aim of this paper is to analyse the organisation of a Hungarian conversation from a complex pragmatic and phonetic view, bringing together phonetic analytic techniques and methods of Conversation Analysis in the framework of a functional pragmatic approach. The main question was what the characteristics of the turns and turn-taking system were and how phonetic features interact in them with pragmatic aspects. Furthermore, we investigate two less-discussed, but important topics as well: the presence and possible factors of extensive prediction in turn-taking system and the connections of phonetic patterns with global discourse structure units. One recording from Hungarian Spontaneous Speech Database (BEA) was used for the study. Three female speakers participated in the conversation: their age and level of education were the same, and they have known each other for years. The material was manually annotated in Praat, the annotation contained the utterance and the word level of each speaker, the overlapping speech, the turns and turn-takings. The frequency, the duration and main pragmatic characteristics of local discourse units were analysed on the one hand. On the other hand, the global structure and timing of the discourse were analysed in terms of the narrative and interactive discourse periods. The results showed that both short pauses and overlapping speech have been common during the turn-takings. The result also shed lights on that half of the turn- takings were carried out in less than 400 ms; these data refer to the extensive prediction of turn-taking based on syntactic, prosodic and pragmatic features of turns.

description: Timing characteristics of spontaneous speech across lifespan


The physiological changes that occur as people age can also be traced in temporal patterns of language. The goal of this research is to analyse the timing characteristics of spontaneous speech in four different age groups: children, teenagers, adults and elderly speakers. The main question of the research is whether and how the temporal characteristics of spontaneous speech change from childhood to old age. The speech materials of the study were selected from three speech databases: children’s material (3–10 years) from GABI (Bóna et al. 2014), teenagers (16–17 years) from TiniBEA (Gyarmathy–Neuberger 2015), and adults (20-90 years) from BEA database (Gósy et al. 2012). We analysed the articulation and speech rate of the speakers, the duration of the speech units, as well as the frequency and duration of pauses. The timing values were compared by age and gender of the speakers. The timing of the phrases appearing in the speech production of
teenagers showed similarities with the statements of adults, while in old age the rate of speech, the articulation and the number of words per speech units also decreased. The results of the research contribute to the understanding of the temporal peculiarities of speech, as well as the systematic, objective description of the changes taking place over the course of life.

description: For the $C^*$-crossed product $C^*(Σ)$ associated with an arbitrary topological dynamical system $Σ= (X, σ)$, we provide a detailed analysis of the commutant, in $C^* (Σ)$, of $C(X)$ and the commutant of the image of $C(X)$ under an arbitrary Hilbert space representation $\tildeπ$ of $C^* (Σ)$. In particular, we give a concrete description of these commutants, and also determine their spectra. We show that, regardless of the system $Σ$, the commutant of $C(X)$ has non-zero intersection with every non-zero, not necessarily closed or self-adjoint, ideal of $C^* (Σ)$. We also show that the corresponding statement holds true for the commutant of $\tildeπ(C(X))$ under the assumption that a certain family of pure states of $\tildeπ(C^* (Σ))$ is total. Furthermore we establish that, if $C(X) \subsetneq C(X)'$, there exist both a $C^*$-subalgebra properly between $C(X)$ and $C(X)'$ which has the aforementioned intersection property, and such a $C^*$-subalgebra which does not have this property. We also discuss existence of a projection of norm one from $C^*(Σ)$ onto the commutant of $C(X)$.

description: The relation of silent pauses and audible breathing in spontaneous speech


Speech is occasionally interrupted by pauses of various length. They are essential parts of human speech. Until the first half of the 20 th century researchers examined the pauses mainly from rhetorical aspects, they analysed the relationship between punctuation of written texts and their spoken realisations. Until now it is not clarified what can be actually considered as pause, how differently pauses can appear in speech, what are their acceptable minimum and maximum durations, and what functions they may have in speech. Empirical researches showed that silent pause is the most common phenomenon in the spontaneous speech, and it has many different functions in spontaneous speech (e.g. breathing, marking syntactic boundaries as well as speech planning difficulties, time for self-repair). There are still many controversies about the relationship between silent pause and breath-taking.


The aim of the present study is to investigate whether breath-taking is subordinated to thinking and is not performed by biological functions in spontaneous speech. Our study focuses on the analysis of the temporal structure of silent pauses and breaths in Hungarian spontaneous speech. We hypothesized that there would be proportional and/or durational differences among pause categories depending on breath-taking.


Results provide detailed information about the relationship between silent pauses and breath-taking. In addition, results can be used in various areas of speech technology, or speech therapy.

description: No abstracts are to be cited without prior reference to the author.The Gulf of Riga is inhabited by a population of small gulf herring. In 1990s thespawning stock biomass of gulfherring has significantly increased because all year classesbeginning from 1989 are rich or above an average level. It is stated that theyear-class strength is detennined by the hydrometeorological conditions inprespawning and spawning periods and by the feeding conditions for larvae. Themean weight-at-age of gulf herring in 1990s is at a very low level ·Iike almost in allregions of the Baltic sea. In 1995-1996 the fecundity of gulf herring was examinedto detennine how fecundity had changed in the conditions of high stock level anddecreased weight-at-age. The gonads of 300 females were analysed each year. Theabsolute fecundity was found in the range from 2783 to 34390 eggs. Fecundity wassignificantly correlated with length, weight and age of the herring. The correlationbetween fecundity and weight was generally higher than tImt with length rth and ageand it increased with the age of the herring. Tlle absolute fecundity in the same agegroups was similar between both years and only in· one age group difTeredstatistically.The results were compared with the data obtained in 1950s and 1970s in the Gulf ofRiga. The relationships between absolute fecundity and biological parameters ofherring were rather similar for aB three periods still some difTerences were found.For herring in seventies when stock was on a much lower level than in other twoperiods the increase of absolute fecundity with the length of the herring was muchhigher. In periods of low spawning stock biomass the prodllction of eggs per weightunit is higher than in periods ofhigh spawniilg stock biomass.

description: We present the initial results of multi-epoch VLBI observations of the 22 GHz H2O masers in the Orion KL region with VERA (VLBI Exploration of Radio Astrometry). With the VERA dual-beam receiving system, we have carried out phase-referencing VLBI astrometry and successfully detected an annual parallax of Orion KL to be 2.29+/-0.10 mas, corresponding to the distance of 437+/-19 pc from the Sun. The distance to Orion KL is determined for the first time with the annual parallax method in these observations. Although this value is consistent with that of the previously reported, 480+/-80 pc, which is estimated from the statistical parallax method using proper motions and radial velocities of the H2O maser features, our new results provide the much more accurate value with an uncertainty of only 4%. In addition to the annual parallax, we have detected an absolute proper motion of the maser feature, suggesting an outflow motion powered by the radio source I along with the systematic motion of source I itself.

description: Effects of age on the use of discourse markers in sociolinguistic
interviews

This study analyzes 8 interviews (1,030 minutes) from the Szeged Sociolinguistic Interview project, focusing on the six most frequently used
discourse markers of Hungarian (hát “well”, ugye “[tag]”, persze “of course”, szóval “so”, egyébként “by the way”, and úgyhogy “thus”) in the four age groups of the corpus. These discourse markers were used most by the 60-70-year-olds, followed by the under-18 group, the over-70 group, and finally the young adults/middle-aged group. In every age group the most frequently used discourse marker was hát, its proportion of use compared to the 6 discourse markers’ average was between 46.06% and 82.25%. The results of the various age groups differ not only in the proportions of discourse markers used, but also in their functions, which is indicative of differences in strategies of forward planning of speech. Younger respondents used discourse markers more for self-correction, word search, and mitigation, and much less for signaling attitudes. In contrast, middle-aged and older respondents used discourse markers for conversation management, self-
reflection, and expression of emotions as well. Respondents in the 60-70 age group produced longer narratives and were more deeply involved in stories, their discourse markers signaling more emotional involvement and various speaker attitudes. Narratives produced by the over-70 group were longest, but these respondents produced more off-topic digressions. Still, they used discourse markers also for commenting on stories they produced.

Inflation from IIB Superstrings with Fluxes

description: We study the conditions needed to have an early epoch of inflationary expansion with a potential coming from IIB superstring theory with fluxes involving two moduli fields. The phenomenology of this potential is different from the usual hybrid inflation scenario and we analize the possibility that the system of field equations undergo a period of inflation in three different regimes with the dynamics modified by a Randall-Sundrum II term in the Friedmann equation. We find that the system can produce inflation and due to the modification of the dynamics, a period of accelerated contraction can follow or preceed this inflationary stage depending on the sign of one of the parameters of the potential. We discuss on the viability of this model in a cosmological context.

description: No abstracts are to be cited without prior reference to the author.The United Nations Agreement on Straddling and Highly Migratory Fish Stocks specifiesthat 'fishery management strategies shall ensure that the risk of cxceeding limit rcference pointsis very low' (Annex 11). Practical application of this principle, in which statistiCal risks arequantified, requires addressing several sources of uncertainty. For example, feference pointsare typically estimated from statistical models based on historical data. Consequcntly, theseestimates always include measurcment error. Furtherrnore, forccasts of the future stock statusare contaminated both by these historical errors and by unknown future variability.
Arsenic speciation studies on some marine invertebrates of British Columbia
Creators: name: Dodd, Matthew
Publisher: name: University of British Columbia

description: Graphite furnace and hydride generation atomic absorption, GFAA and HGAA, techniques have been developed and applied to the determination of arsenic concentrations in some marine invertebrates, mainly bivalves and gastropods, of British Columbia. Total arsenic concentrations in bivalves vary with species, ranging from 0.6-9.1 μg g⁻¹ (wet weight basis). Arsenic concentrations in the bivalve shells show a wider range of 0.1 to 26.3 μg g⁻¹ (dry weight basis). Gastropods show relatively higher arsenic concentrations in the soft tissues, 17.3-48.4 fig μg g⁻¹, and concentrations in the shells range from 1.4 to 16.3 fig μg g⁻¹. There is no correlation between arsenic levels in the soft-tissues and shells. There is also no correlation between arsenic levels in the organisms and the surrounding sediments and sediment pore waters. HPLC-GFAA techniques have been developed and used for the separation and quantitation of-arsenite, arsenate, methylarsonic acid, dimethylar-sinic acid, arsenobetaine, arsenocholine iodide and tetramethylarsonium iodide. This technique together with TLC, NMR, FAB and thermospray LCMS were employed for the detection of water-soluble arsenic compounds in 5 species of clams - Butter clam Saxidomus giganteus. Horse clam Schizothoerus nuttalli. Soft-shelled clam Mva arenaria. Native-littleneck clam Protothaca staminea and Manila clam Venerupis laponica. Varying amounts of arsenobetaine and tetramethylarsonium ion are found in all the clams. Butter clams show the pres ence of a third compound which appears to be trimethylarsine oxide. Small amounts of unknown arsenic containing compounds are present which are yet to be characterized . Arsenic speciation in 3 gastropods was also examined. The Northwest neptune Neptunea lvrata. the Thick-ribbed whelk Berinpius crebriscotata and Phoenician whelk Neptunea phoenicius all contain arsenobetaine and at least two unidentified arsenicals.
