description: In 1998 the Supernova Cosmology Project and the High-z Supernova Search Team published observations that showed the universe is expanding at an ever-increasing rate. The simplest explanation is a nonzero zero-point energy density. Observations have measured the energy density to be ρvac~10-8erg/cm3. A possible source of this energy density is the fluctuations of quantum fields. However, a vacuum density of 120 orders of magnitude larger is calculated from theory. Here, a toy model is used to study if considering composite particles with mass balance conditions proposed by Wolfgang Pauli in 1951 can be used to calculate a finite zero-point energy densities closer in agreement with observation. Results are analyzed for various numbers of total particles. This study finds both negative and positive energy densities are possible, with positive energy more probable than negative.

description: The set definition of distal cholangiocarcinomas and adenocarcinomas of the pancreatic head is challenged by their close anatomical relation, similar growth pattern, and corresponding therapeutic outcome. They show a mutual development during embryologic organ formation and share phenotypic characteristics. This review will highlight the similarities with regard to the common origin of their primary organs, histopathological similarities, and modern clinical management. Thus, we propose to subsume those entities under a common superfamily.

Cycle traffic in the regional transport model of Norway
Creators: name: Tørset, Trude
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2012

description: The regional transport model developed in Norway over the last 12 years will from now on be used also for urban transport. Can the transport model also be used to model changes in the demand for cycling in its current form? Is it enough to detail the coding of the transport network in more detail, or is it necessary to include bike‐specific variables in the demand model to achieve this? These two issues are addressed in this paper by going in depth in the modeled and actual travel patterns in an area south of Trondheim, where an infrastructure measure for cyclists is scheduled in 2014. The cycle measure is a bridge for pedestrians and cyclists, which will reduce the travel distance, and hilliness on the route between two districts. Data sources for the actual travel patterns is the national travel survey conducted in 2009 and 2010, with an enhanced range of Trondheim. This is compared with model calculations at a paramount level, within areas of mode choice, trip length distribution for the various modes of transport, within the private travel purposes represented in the travel survey. Moreover, a short time registration of cycle traffic is carried out on roads in the near‐by area of the scheduled bridge. In addition, two small surveys are conducted in the same period aimed at households and workers. Interviewees are asked to give information about their travel patterns over the two previous days. Trips that could potentially to use the new bridge are labeled specifically. In addition, they were asked about how the bridge could affect their travel patterns. The results suggest that the transport net must be coded in more detail than we have done up until now. Both experience reported in the literature and results from this study, indicates that hilliness should be included in the net coding and skimming of level of service data, both because it is an important explanation factor to the demand for cycle traffic, but also to improve the net assignment.

description: A 'pulsar timing array' (PTA), in which observations of a large sample of pulsars spread across the celestial sphere are combined, allows investigation of 'global' phenomena such as a background of gravitational waves or instabilities in atomic timescales that produce correlated timing residuals in the pulsars of the array. The Parkes Pulsar Timing Array (PPTA) is an implementation of the PTA concept based on observations with the Parkes 64-m radio telescope. A sample of 20 ms pulsars is being observed at three radio-frequency bands, 50 cm (similar to 700MHz), 20 cm (similar to 1400 MHz), and 10 cm (similar to 3100 MHz), with observations at intervals of two to three weeks. Regular observations commenced in early 2005. This paper describes the systems used for the PPTA observations and data processing, including calibration and timing analysis. The strategy behind the choice of pulsars, observing parameters, and analysis methods is discussed. Results are presented for PPTA data in the three bands taken between 2005 March and 2011 March. For 10 of the 20 pulsars, rms timing residuals are less than 1 mu s for the best band after fitting for pulse frequency and its first time derivative. Significant 'red' timing noise is detected in about half of the sample. We discuss the implications of these results on future projects including the International Pulsar Timing Array and a PTA based on the Square Kilometre Array. We also present an 'extended PPTA' data set that combines PPTA data with earlier Parkes timing data for these pulsars.

description: Strong-coupling between light and matter produces hybridized states (polaritons) whose delocalization and electromagnetic character allow for novel modifications in spectroscopy and chemical reactivity of molecular systems. Recent experiments have demonstrated remarkable distance-independent long-range energy transfer between molecules strongly coupled to optical microcavity modes. To shed light on the mechanism of this phenomenon, we present the first comprehensive theory of polariton-assisted remote energy transfer (PARET) based on strong-coupling of donor and/or acceptor chromophores to surface plasmons. Application of our theory demonstrates that PARET up to a micron is indeed possible. In particular, we report two regimes for PARET: in one case, strong-coupling to a single type of chromophore leads to transfer mediated largely by surface plasmons while in the other case, strong-coupling to both types of chromophores creates energy transfer pathways mediated by vibrational relaxation. Importantly, we highlight conditions under which coherence enhances or deteriorates these processes. For instance, while exclusive strong-coupling to donors can enhance transfer to acceptors, the reverse turns out not to be true. However, strong-coupling to acceptors can shift energy levels in a way that transfer from acceptors to donors can occur, thus yielding a chromophore role-reversal or “carnival effect”. This theoretical study demonstrates the potential for confined electromagnetic fields to control and mediate PARET, thus opening doors to the design of remote mesoscale interactions between molecular systems.

Whole cell models of the Escherichia coli peptidoglycan and the identification of iron-sulfur cluster and zinc binding sites in predicted 3D protein structures
Creators: name: Wehrspan, Zachary J.
Publisher: name: University of Iowa
Year: 2024
Subjects: public abstract

description: Computational modeling of complex biological systems allows researchers to probe and explore systems in ways that might otherwise be impossible. The work presented here computationally examines two such types of systems: (1) the peptidoglycan and periplasm and (2) iron sulfur clusters and zinc binding sites in proteins. The first major part of my thesis work focuses on the bacterial peptidoglycan. To do this, I first assembled and combined seemingly disparate pieces of experimental data to generate consensus 3D whole cell models of the peptidoglycan for the first time, asking whether the experimental data can be synthesized into a 3D model in a coherent manner. To accomplish this, I extended experimentally determined glycan strand distributions, added the highly abundant and covalently bonded Braun’s lipoprotein to the peptidoglycan, and incorporated a variety of peptide crosslinks at realistic proportions. With a static model of the peptidoglycan constructed, I then moved on to simulating its conformational dynamics. To do so, I first derived a coarse-grained forcefield from all-atom molecular dynamics simulations of peptidoglycan fragments. Using this coarse-grained forcefield, I then conducted Langevin dynamics simulations of the peptidoglycan with different levels of crosslinking and connections to Braun’s lipoprotein. These simulations demonstrated agreement with the experimentally observed physical properties such as outer membrane to peptidoglycan distance, pore size distribution, and thickness of the peptidoglycan, indicating a plausible model. With this model of the peptidoglycan, I then built a preliminary model of the whole cell periplasm by adding coarse-grained models of the most abundant proteins and protein complexes. I then performed the first whole-cell simulation of the bacterial periplasm and showed that proteins of varying sizes can move through the peptidoglycan despite the relative short duration of the simulation.
description: The second major part of my thesis work involves protein structure prediction. Recent advances in 3D protein structure prediction have resulted in near experimental quality structures via the program AlphaFold2. However, AlphaFold2 does not build in bound ligands such as metals into the structures and these can be crucial to a protein’s function. To identify iron sulfur clusters and zinc binding sites in AlphaFold2 predicted protein structures, my coworkers and I developed a method of exhaustively checking possible ligand orientations in 360,000+ proteins. I showed that AlphaFold2 consistently builds known iron sulfur clusters and zinc binding sites and identified thousands of potentially novel sites.
The partitioning of atmospheric iodine-129 in a shallow sand aquifer at Sturgeon Falls, Ontario.

Subjects: subject: Hydrology.

description: The transport and partitioning of 129I has been examined for a shallow groundwater flow system at Sturgeon Falls in northeastern Ontario. Recharge into a sandy surficial postglacial deltaic aquifer occurs in the vicinity of a seasonally-wet boreal forest. Concentrations of stable iodine, 129I, tritium, radiocarbon, stable isotopes and major ions were measured on samples of groundwater and precipitation. The present-day tritium profile delineates the position of the early 1960's thermonuclear bomb-pulse at a depth of approximately 12 m. The concentrations of stable iodine for groundwaters above, near and below the present-day bomb pulse range from 0.07 to 1.7 ppb. The groundwater in the lower aquifer is practically tritium-free (<2 TU) and is considered to be pre-bomb in age. The lesser concentrations of 129I in Sturgeon Falls groundwaters, compared with those from other studies in central Canada, suggest that the levels of 129I in these groundwaters may have been attenuated by complexation or ion exchange with organic materials in the near-surface soil horizons. Additionally, the concentrations of 129I in the mine waters of the Con Mine, in Yellowknife, NWT were examined. (Abstract shortened by UMI.)

description: Background: Metastasis is the most frequent type of recurrence in gastrointestinal (GI) cancers, and there is an emerging potential for new diagnostic and therapeutic approaches, especially in the cases of metastatic GI carcinomas. The expression profiles of circulating exosomal microRNAs are of particular interest as novel non-invasive diagnostic and prognostic biomarkers for improved detection of GI cancers in body fluids, especially in the serum of patients with recurrent cancers. The aim of this study is to systematically review primary studies and identify the miRNA profiles of serum exosomes of GI cancers. Methods and design: This systematic review will be reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidance. Relevant studies will be identified through a comprehensive search of the following main electronic databases: PubMed, Web of Science, Embase, Scopus, and Google Scholar, with no language restrictions (up to July 2017). Full copies of articles will be identified by a defined search strategy and will be considered for inclusion against pre-defined criteria. The quality assessment of the included studies will be performed by the Newcastle-Ottawa Scale (NOS). Data will be analyzed using Stata software V.12. Publication bias will be assessed by funnel plots, Beggs’ and Eggers’ tests. The levels of evidence for primary outcomes will be evaluated using the GRADE criteria. Discussion: The analysis of circulating exosomal miRNA profiles provides attractive screening and non-invasive diagnostic tools for the majority of solid tumors including GI cancers. There is limited information regarding the relationship between serum exosomal miRNA profiles and the pathological condition of patients with different GI cancers. Since there is no specific biomarker for GI cancers, we aim to suggest a number of circulating exosomal miRNA candidates as potential multifaceted GI cancer biomarkers for clinical utility.

description: Signals from radio pulsars show a wavelength-dependent delay due to dispersion in the interstellar plasma. At a typical observing wavelength, this delay can vary by tens of microseconds on 5-yr time-scales, far in excess of signals of interest to pulsar timing arrays, such as that induced by a gravitational wave background. Measurement of these delay variations is not only crucial for the detection of such signals, but also provides an unparalleled measurement of the turbulent interstellar plasma at astronomical unit (au) scales. In this paper we demonstrate that without consideration of wavelength-independent red noise, ‘simple’ algorithms to correct for interstellar dispersion can attenuate signals of interest to pulsar timing arrays. We present a robust method for this correction, which we validate through simulations, and apply it to observations from the Parkes Pulsar Timing Array. Correction for dispersion variations comes at a cost of increased band-limited white noise. We discuss scheduling to minimize this additional noise, and factors, such as scintillation, that can exacerbate the problem. Comparison with scintillation measurements confirms previous results that the spectral exponent of electron density variations in the interstellar medium often appears steeper than expected. We also find a discrete change in dispersion measure of PSR J1603−7202 of ∼2 × 10−3 cm−3 pc for about 250 d. We speculate that this has a similar origin to the ‘extreme scattering events’ seen in other sources. In addition, we find that four pulsars show a wavelength dependent annual variation, indicating a persistent gradient of electron density on an au spatial scale, which has not been reported previously.
Evaluation of molecular typing methods to discriminate between isolates of Neisseria gonorrhoeae: Restriction endonuclease analysis, ribotyping and pulsed field gel electrophoresis.

description: In the present study, three molecular methods, restriction enzyme (RE) analysis of chromosomal DNA, restriction fragment length polymorphism (RFLP) analysis of ribosomal RNA (rRNA) genes (ribotyping) and pulsed field gel electrophoresis (PFGE) were evaluated for their ability to discriminate within and between five groups of gonococcal isolates. By comparing the Re analysis and ribotyping for 100 gonococcal isolates as well as PFGE analysis for 26 of the 100 gonococcal isolates, there were twenty RE patterns, eleven ribotypes and twenty-five PFGE patterns produced. Overall, PFGE produced greater discrimination between isolates within the same A/S classes than ribotyping or RE analysis. In some cases, as with arginine-requiring strains or strains from an outbreak, several molecular methods should be tested in order to produce maximum discrimination between strains. Arginine auxotyphy is commonly encountered in Neisseria gonorrhoeae, comprising 40-60% of clinical isolates, including isolates with multiple nutritional requirement. Arginine (Arg) and uracil (U)-requiring strains are common in Canada. These AU isolates may have a deficiency affecting both the arginine and uracil biosynthesis pathways. Isolates may have a deficiency affecting both the arginine and uracil biosynthesis pathways. Isolates which require citrulline (C) alone for growth are very rare. Only 2 of 1540 of the arginine-requiring isolates in the culture collection of the NLSTD were citrulline-requiring. Strains requiring citrulline may be mutant for one of two enzymes, ornithine transcarbamoylase (OTCase), which catalyze L-citrulline formation from L-ornithine and carbamoylohosphate, or carbamoylphosphate synthetase (CPSase), which implicated in arginine and uracil biosynthesis pathways. Strains which are CPSase deficient may also be mutant in pyrimidine (U) biosynthesis. Twenty-two CU requiring isolates and two C requiring isolates were tested for OTCase and CPSase activities. The 22 CU auxotype possessed OTCase activity, but did not have CPSase activity. The 2 isolates requiring citrulline alone had CPSase activity, but did not have OTCase activity.

Manipulation of uniformly sheared turbulence using curvature and thin ribbons.
Creators: name: Chebbi, Brahim.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1994
Subjects: subject: Engineering, Mechanical.

description: A nearly homogeneous uniformly sheared turbulent flow was subjected to curvature in the same direction as the mean shear and then to curvature reversal. The adjustment of the turbulence structure to a change of the value of the curvature parameter, $S={{\overline{U}\sb{c}\over R\sb{c}}\over{\partial\overline {U}\over\partial\sb{n}}}$, is investigated. The structural parameter, $K\sb{uv}={\overline{uv}\over{q\sp2}}$, adjusts faster when the effects of curvature are stronger. For the small values of S obtained in the present investigation the adjustment of $K\sb{uv}$ depends on both the original and new values of S as the flow is subjected to curvature reversal. Qualitative and quantitative similarities between the present flow and curved turbulent boundary layers are identified. A thin ribbon is placed in rectilinear and curved nearly homogeneous uniformly sheared flows. The development of the wake of the thin ribbon is investigated. The mean flow characteristics of the wake of the thin ribbon developing in rectilinear shear flow present a certain degree of self similarity and some resemblance to the characteristics of the wake of a LEBU in the outer part of turbulent boundary layers.

description: This paper presents the discovery and timing parameters for five millisecond pulsars (MSPs),four in binary systems with probable white dwarf companions and one isolated, found in ongoing processing of the High Time Resolution Universe Pulsar (HTRU) survey. We also present high-quality polarimetric data on four of them. These further discoveries confirm the high potential of our survey in finding pulsars with very short spin periods. At least two of these five MSPs are excellent candidates to be included in the pulsar timing array projects. Thanks to the wealth of MSP discoveries in the HTRU survey, we revisit the question of whether the luminosity distributions of isolated and binary MSPs are different. Using the Cordes and Lazio distance model and our new and catalogue flux density measurements, we find that 41 of the 42 most luminous MSPs in the Galactic disc are in binaries, and a statistical analysis suggests that the luminosity functions differ with 99.9 per cent significance. We conclude that the formation process that leads to solitary MSPs affects their luminosities, despite their period and period derivatives being similar to those of pulsars in binary systems.

description: Artificial light is gaining attention as a potential stressor to aquatic ecosystems. Artificial lights located near streams increase light levels experienced by stream invertebrates and we hypothesized light would depress night drift rates. We also hypothesized that the effect of light on drift rates would decrease over time as the invertebrates acclimated to the new light level over the course of one month’s exposure. These hypotheses were tested by placing Gammarus spp. in eight, 75 m × 1 m artificial flumes. One flume was exposed to strong (416 lx) artificial light at night. This strong light created a gradient between 4.19 and 0.04 lx over the neighboring six artificial flumes, while a control flume was completely covered with black plastic at night. Night-time light measurements taken in the Berlin area confirm that half the flumes were at light levels experienced by urban aquatic invertebrates. Surprisingly, no light treatment affected gammarid drift rates. In contrast, physical activity measurements of in situ individually caged G. roeseli showed they increased short-term activity levels in nights of complete darkness and decreased activity levels in brightly lit flumes. Both nocturnal and diurnal drift increased, and day drift rates were unexpectadly higher than nocturnal drift.

description: Reactivation of fetal gene expression patterns has been implicated in common cardiac diseases in adult life including left ventricular (LV) hypertrophy (LVH) in arterial hypertension. Thus, increased wall stress and neurohumoral activation are discussed to induce the return to expression of fetal genes after birth in LVH. We therefore aimed to identify novel potential candidates for LVH by analyzing fetal-adult cardiac gene expression in a genetic rat model of hypertension, i.e. the stroke-prone spontaneously hypertensive rat (SHRSP). To this end we performed genome-wide transcriptome analysis in SHRSP to identify differences in expression patterns between day 20 of fetal development (E20) and adult animals in week 14 in comparison to a normotensive rat strain with contrasting low LV mass, i.e. Fischer (F344). 15232 probes were detected as expressed in LV tissue obtained from rats at E20 and week 14 (p < 0.05) and subsequently screened for differential expression. We identified 24 genes with SHRSP specific up-regulation and 21 genes with down- regulation as compared to F344. Further bioinformatic analysis presented Efcab6 as a new candidate for LVH that showed only in the hypertensive SHRSP rat differential expression during development (logFC = 2.41, p < 0.001) and was significantly higher expressed in adult SHRSP rats compared with adult F344 (+ 76%) and adult normotensive Wistar-Kyoto rats (+ 82%). Thus, it represents an interesting new target for further functional analyses and the elucidation of mechanisms leading to LVH. Here we report a new approach to identify candidate genes for cardiac hypertrophy by combining the analysis of gene expression differences between strains with a contrasting cardiac phenotype with a comparison of fetal-adult cardiac expression patterns.

description: Device-to-device (D2D) communication is becoming an increasingly important technology in future networks with the climbing demand for local services. For instance, resource sharing in the D2D network features ubiquitous availability, flexibility, low latency and low cost. However, these features also bring along challenges when building a satisfactory resource sharing system in the D2D network. Specifically, user mobility is one of the top concerns for designing a cooperative D2D computational resource sharing system since mutual communication may not be stably available due to user mobility. A previous endeavour has demonstrated and proven how connectivity can be incorporated into cooperative task scheduling among users in the D2D network to effectively lower average task execution time. There are doubts about whether this type of task scheduling scheme, though effective, presents fairness among users. In other words, it can be unfair for users who contribute many computational resources while receiving little when in need. In this paper, we propose a novel blockchain-based credit system that can be incorporated into the connectivity-aware task scheduling scheme to enforce fairness among users in the D2D network. Users’ computational task cooperation will be recorded on the public blockchain ledger in the system as transactions, and each user’s credit balance can be easily accessible from the ledger. A supernode at the base station is responsible for scheduling cooperative computational tasks based on user mobility and user credit balance. We investigated the performance of the credit system, and simulation results showed that with a minor sacrifice of average task execution time, the level of fairness can obtain a major enhancement.

description: Das vorliegende Forschungsvorhaben untersucht, ob und inwieweit durch Zivil- und öffentliches Recht nachhaltiger Konsum in der Kauf- und Nutzungsphase von Produkten gefördert werden kann. Während bislang in erster Linie öffentlich-rechtliche Instrumente, die den Hersteller von Produkten adressieren, zur Förderung nachhaltigen Konsums eingesetzt werden, ist diesbezüglich das Zivilrecht, insbesondere das Lauterkeits- und Gewährleistungsrecht, kaum Gegenstand der Forschung gewesen. Darüber hinaus fehlt es gänzlich an Erkenntnissen, inwieweit eine Verknüpfung öffentlich-rechtlicher und zivilrechtlicher Instrumente nachhaltigen Konsum fördert. Die rechtssystematisch-intradisziplinäre Untersuchung und die ökonomische Wirksamkeitsanalyse offenbaren, dass die genannten Rechtsgebiete um Informations-, Gewährleistungs- und Klagerechte ergänzt werden sollten.

description: Most operators agree they must move towards a single technology Next Generation Network (NGN), based on Internet Protocol (IP) which can provide a ubiquitous bit-transport system for all network services. But without a sound strategy to deliver NGN IP to the millions of users through the Access Network this will be of little use, warns Carsten Storbeck; there are some cardinal rules which must be followed.

description: Searches for transient astrophysical sources often reveal unexpected classes of objects that are useful physical laboratories. In a recent survey for pulsars and fast transients, we have uncovered four millisecond-duration radio transients all more than 40° from the Galactic plane. The bursts' properties indicate that they are of celestial rather than terrestrial origin. Host galaxy and intergalactic medium models suggest that they have cosmological redshifts of 0.5 to 1 and distances of up to 3 gigaparsecs. No temporally coincident x- or gamma-ray signature was identified in association with the bursts. Characterization of the source population and identification of host galaxies offers an opportunity to determine the baryonic content of the universe.

description: Morphological processing is the use of morphological structure during word reading. This study examined the role of morphological processing in automaticity in word reading processes and asked whether automatic morphological processing made a unique contribution to decoding, oral reading fluency, and reading comprehension outcomes of middle school students. In addition, this study asked whether these contributions were moderated by having a word reading difficulty.
description: Seventh- and eighth-grade students (n = 80) participated in the study. Students were divided into two reading ability groups: proficient readers (n = 55) and student with word reading difficulties (n = 25). They completed two remote sessions: a standardized assessment session and an experimental task session. A battery of six standardized measures was administered to assess students’ decoding, oral reading fluency, reading comprehension, and oral language abilities. In addition, eight computer-administered experimental tasks (four different tasks, each with a masked and an unmasked version) were used to measure automaticity in reading morphological words (e.g., eagerness) and nonmorphological words (e.g., embarrass). Three analysis approaches were used in a conceptual replication of two previous studies (Roembke et al., 2019, 2021): mixed analyses of variance (ANOVAs), hierarchical regressions, and commonality analyses.
description: Results indicated automaticity in reading nonmorphological words most consistently accounted for unique variance in decoding and oral reading fluency. However, automaticity in reading morphological words was the only independent variable that accounted for unique variance in reading comprehension, and it also accounted for unique variance in oral reading fluency. There was no evidence that the unique contribution of morphological processing to oral reading fluency or reading comprehension was moderated by having a word reading difficulty. These findings suggest that the role of morphological processing in reading may still be developing in middle school students.

title: Perception Change With Ubiquitous AR in Social and Individual Scenarios
Creators: name: Eghtebas, Chloe
Publisher: name: European Society for Socially Embedded Technologies (EUSSET)

description: AR will become ubiquitous and with it, many challenges emerge in a socio-technical context. Given the wide range of devices not all AR is made equal. From what the AR is technically capable of, to who is using it, and how it looks; there are different perceptions of different devices. From the heterogeneous landscape of AR, the social circumstances of informational inequality can emerge giving way to a social advantage or hierarchy. Furthermore, when AR becomes ubiquitous, it can be used to mediate perceptions of reality which can be applied in moderating communication in a multi-user environment [Mann (2002)]. In this Doctoral Consortium (DC) paper I motivate a vision, outline some challenges, report on progress already made and speculate the next steps in how to understand and direct the influence of perceptions to overcome, rather than increase the prevalence of social inequality.
