description: Baryon acoustic oscillations (BAO), known as one of the largest cosmological objects, is now recognized as standard cosmological tool to measure geometric distances via the Alcock-Paczynski effect, by which the observed BAO exhibits characteristic anisotropies in addition to the redshift distortions. This implies that once we know the correct distances to the observed BAO, the tip points of baryon acoustic peaks in the anisotropic correlation function of galaxies, $ξ(σ,π)$, can form a great circle (hereafter 2D BAO circle) in the $σ$ and $π$ plane, where $σ$ and $π$ are the separation of galaxy pair parallel and perpendicular to the line-of-sight, respectively. This 2D BAO circle remains unchanged under the variations of the unknown galaxy bias and/or coherent motion, while it varies transversely and radially with respect to the variations of $D_A$ and $H^{-1}$, respectively. Hereby the ratio between transverse distance $D_A$ and the radial distance $H^{-1}$ reproduces the intrinsic shape of 2D BAO circle, which is {\it a priori} given by the known broadband shape of spectra. All BAO peaks of $ξ(σ,π)$ are precisely calculated with the improved theoretical model of redshift distortion. We test this broadband Alcock--Paczynski method using BOSS--like mock catalogues. The transverse and radial distances are probed in precision of several percentage fractional errors, and the coherent motion is observed to match with the fiducial values accurately.

description: Adjusting for baseline values and covariates is a recurrent statistical problem in medical science. In particular, variance heteroscedasticity is non-negligible in experimental designs and ignoring it might result in false conclusions. Approximate inference methods are developed to test null hypotheses formulated in terms of adjusted treatment effects and regression parameters in general analysis of covariance designs with arbitrary numbers of factors. Variance homoscedasticity is not assumed. The distributions of the test statistics are approximated using Box-type approximation methods. Extensive simulation studies show that the procedures are particularly suitable when sample sizes are rather small. A real data set illustrates the application of the methods.

description: We replicate Meissner (Exp Econ 19:281–298, 2016), where debt aversion was reported for the first time in an intertemporal consumption and saving problem. While Meissner (2016) uses a German sample, our participants are US undergraduate students. All of the original study’s main findings replicate with similar effect sizes. Additionally, we extend the original analysis by introducing a new individual index of debt aversion, which we use to compare debt aversion across countries. Interestingly, we find no significant differences in debt aversion between the original German and the new US sample. We then test whether debt aversion correlates with individual characteristics such as gender, cognitive reflection ability, and risk aversion. Overall, this paper confirms the importance of debt aversion in intertemporal consumption and saving problems and validates the approach of Meissner (2016).
Unspoken commandments: Contemporary correctional officer work cultures and their influence on prison conditions
Creators: Schultz, William
Publisher: name: University of Alberta Library
Year: 2023

I draw on interviews with 131 Canadian correctional officers (or COs), all of whom work in four western Canadian prisons. Building on existing Canadian and international CO research, my dissertation analyzes specific facets of CO workplace cultures in provincial prisons in Western Canada. Provincial prisons, which house prisoners who are awaiting trial or are sentenced to less than two years of custody, house the largest group of prisoners in Canada, but are comparatively under-researched. In this dissertation, I examine how officers practice and enact their roles as COs, detailing specific features of their habitus and demonstrating how it shapes workplace and occupational cultures, attitudes, and behaviours in unproductive ways. The broader, guiding question for this dissertation is as follows: how do officer workplace and occupational cultures shape prisons and prison operations? To answer this, I examine how the CO habitus shapes officer cultural values, and in turn demonstrate how these cultural values impact the daily operation of provincial prisons.

This dissertation is broken into three central chapters, with a methodological addendum representing chapter four. Each of these chapters targets a specific aspect of how officer cultures function on a day-to-day basis. Chapter 1 focuses on how COs discuss and enact gendered organizational lenses within their work, demonstrating how gender distinctly shapes the perspectives and experiences of new COs. I conclude by discussing the central role that gendered organizational lenses play in helping officers deal with broader organizational shifts.

In Chapter 2, I focus on how COs interact with use of force. Specifically, I examine how COs use and interact with force as a means of coercive governance, structuring how prison staff maintain control of prison environments. This article differs notably from other research on the topic, as I demonstrate how actions that are often discussed as “corruption” are often directly informed by how COs interact with broader organizational frameworks.

In Chapter 3, I examine how COs perceive themselves as vulnerable. Building off of Sierra-Arévalo’s concept of a “danger imperative,” I argue that COs interpret nearly every decision they make through a lens of personal vulnerability. I provide specific details of how COs do this, identify the broader importance of vulnerability to COs, and identify points that officers routinely identify when discussing themselves as vulnerable. Finally, in Chapter 4, I discuss my own positionality as a former CO, and identify the specific features of my interaction with officer culture and how that impacted my research.
Clusters, Clouds, and Correlations: Relating Young Clusters to Giant Molecular Clouds in M33 and M31
Creators: Peltonen, Joshua CW
Publisher: name: University of Alberta Library
Year: 2023

Using young clusters and giant molecular clouds (GMCs), we constrain timescales and distances involved in the star formation process in the Triangulum (M33) and Andromeda (M31) galaxies. The young star clusters come from the PHATTER catalogue, with 1214 clusters in M33 and the PHAT catalogue, with 1249 clusters in M31. These cluster catalogues have the ages of their members measured using colour-magnitude diagram fitting. In M33, we compare these clusters to 444 GMCs identified from an ALMA 12CO(2-1) survey with 35 pc resolution. In M31, we compare the clusters to 251 GMCs identified from a CARMA 12CO(1-0) survey with 20 pc resolution. By comparing the separations between clusters and their nearest GMC, we find that younger clusters are preferentially located near GMCs, while older clusters have separations consistent with a random distribution. Performing two-point correlation on our clusters and GMCs reveals that younger clusters are likely to be found at small separations from other young clusters. In M33, where the cluster catalogue contains younger clusters, we find through cross-correlation analysis that GMCs and clusters ≤10 Myr are statistically associated. This association between GMCs and clusters decreases until the clusters are ≈ 18 Myr, where the clusters and GMCs then appear randomly distributed for older clusters. This transition to a more random distribution can be explained by a simple drift model where the clusters have a velocity dispersion of 5-10 km/s with respect to the surrounding gas. By finding the number of spatially overlapping young clusters and GMCs in M33, we estimate that clusters spend 4-6 Myr emitting feedback into their parent GMC. We then estimate that GMCs in M33 have a total lifetime of 11-15 Myr.

description: Introduction: In pediatric liver transplantation (pLT), hepatic artery thrombosis (HAT) is associated with inferior transplant outcome. Hepatic artery reconstruction (HAR) using an operating microscope (OM) is considered to reduce the incidence of HAT. Methods: HAR using an OM was compared to a historic cohort using surgical loupes (SL) in pLT performed between 2009 and 2020. Primary endpoint was the occurrence of HAT. Secondary endpoints were 1-year patient and graft survival determined by Kaplan-Meier analysis and complications. Multivariate analysis was used to identify independent risk factors for HAT and adverse events. Results: A total of 79 pLTs were performed [30 (38.0%) living donations; 49 (62.0%) postmortem donations] divided into 23 (29.1%) segment 2/3, 32 (40.5%) left lobe, 4 (5.1%) extended right lobe, and 20 (25.3%) full-size grafts. One-year patient and graft survival were both 95.2% in the OM group versus 86.2% and 77.8% in the SL group (p = .276 and p = .077). HAT rate was 0% in the OM group versus 24.1% in the SL group (p = .013). One-year patient and graft survival were 64.3% and 35.7% in patient with HAT, compared to 93.9% and 92.8% in patients with no HAT (both p < .001). Multivariate analysis revealed HAR with SL (p = .022) and deceased donor liver transplantation (DDLT) (p = .014) as independent risk factors for HAT. The occurrence of HAT was independently associated with the need for retransplantation (p < .001) and biliary leakage (p = .045). Conclusion: In pLT, the use of an OM is significantly associated to reduce HAT rate, biliary complications, and graft loss and outweighs the disadvantages of delayed arterial perfusion and prolonged warm ischemia time (WIT).
Vertical Resource Partitioning and Sexuality of Three Sympatric Species of Red Sea Sandfishes (Xyrichtys melanopus, Labridae; Trichonotus nikii, Trichonotidae; Gorgasia sp., Congridae)
Creators: name: Krall, Marianne Martha
Publisher: name: Digital Repository at the University of Maryland
Year: 1988

description: Three species of marine sandfishes were studied from 1984 to 1986. Their inter- and intraspecific behavior was monitored during the daylight hours to examine interactions that could result in the vertical stratification of the species over the sandy bottom within the fringing and patch reefs in the north Red Sea. Horizontal plankton tows were taken at three heights and three times a day. These samples were compared to stomach contents of the fishes to determine the trophic relationships in the community and their affects on spatial relations between the species . Prey specificities of the fishes were determined by using an electivity measure. Using paraffin histology, Xyrichtys melanopus was determined to be a monandric protogynous hermaphrodite and Trichonotus nikii, a gonochorist. Previous work on the mating systems and territoriality of all three sandfish species helped in part to explain the vertical spatial arrangement of the sandfish species within the community. Effects of pollution on the b iota of the Northern Gulf of Aqaba are noted.

description: We propose color magnetism as a generalization of the ordinary Heisenberg (anti-)ferro magnets on a triangular lattice. Vortex matter consisting of an Abrikosov lattice of non-Abelian vortices with color magnetic fluxes shows a color ferro or anti-ferro magnetism, depending on the interaction among the vortex sites. A prime example is a non-Abelian vortex lattice in rotating dense quark matter, showing a color ferromagnetism. We show that the low-energy effective theory for the vortex lattice system in the color ferromagnetic phase is described by a 3+1 dimensional $CP^{N-1}$ nonlinear sigma model with spatially anisotropic couplings. We identify gapless excitations independent from Tkachenko modes as color magnons, that is, Nambu-Goldstone modes propagating in the vortex lattice with an anisotropic linear dispersion relation $ω_p^2 = c_{xy}^2(p_x^2+p_y^2) + c_z^2 p_z^2$. We calculate the transition temperature between the ordered and disordered phases, and apply it to dense quark matter. We also identify the order parameter spaces for color anti-ferromagnets.

description: Random Matrix Theory has been successfully applied to lattice Quantum Chromodynamics. In particular, a great deal of progress has been made on the understanding, numerically as well as analytically, of the spectral properties of the Wilson Dirac operator. In this paper, we study the infra-red spectrum of the Wilson Dirac operator via Random Matrix Theory including the three leading order $a^2$ correction terms that appear in the corresponding chiral Lagrangian. A derivation of the joint probability density of the eigenvalues is presented. This result is used to calculate the density of the complex eigenvalues, the density of the real eigenvalues and the distribution of the chiralities over the real eigenvalues. A detailed discussion of these quantities shows how each low energy constant affects the spectrum. Especially we consider the limit of small and large (which is almost the mean field limit) lattice spacing. Comparisons with Monte Carlo simulations of the Random Matrix Theory show a perfect agreement with the analytical predictions. Furthermore we present some quantities which can be easily used for comparison of lattice data and the analytical results.

description: RNA viruses in the Picornaviridae family express a large 250 kDa viral polyprotein that is processed by virus-encoded proteinases into mature functional proteins with specific functions for virus replication. One of these proteins is the highly conserved enteroviral transmembrane protein 3A that assists in reorganizing cellular membranes associated with the Golgi apparatus. Here, we studied the molecular properties of the Coxsackievirus B3 (CVB3) protein 3A with regard to its dimerization and its functional stability. By applying mutational analysis and biochemical characterization, we demonstrate that protein 3A forms DTT-sensitive disulfide-linked dimers via a conserved cytosolic cysteine residue at position 38 (Cys38). Homodimerization of CVB3 protein 3A via Cys38 leads to profound stabilization of the protein, whereas a C38A mutation promotes a rapid proteasome-dependent elimination of its monomeric form. The lysosomotropic agent chloroquine (CQ) exerted only minor stabilizing effects on the 3A monomer but resulted in enrichment of the homodimer. Our experimental data demonstrate that disulfide linkages via a highly conserved Cys-residue in enteroviral protein 3A have an important role in the dimerization of this viral protein, thereby preserving its stability and functional integrity.
Evaluation of Brassica root architectural traits
Creators: Yang, Chunxiao

Year: 2023

Given the roles of roots in water and nutrient uptake, anchorage, and storage of resources, root system architecture (RSA) can have a major impact on plant growth and development. The root systems of Brassica species, an important group that includes many field and horticultural crops, is complex. Comparative studies of RSA that combine morphological and genetic analyses are limited, particularly because the evaluation of root traits can be tedious and time-consuming. In this thesis, a semi-hydroponic system was optimized for phenotyping RSA traits in Brassica napus, and then utilized for the study of eight RSA traits in a collection of 379 Brassica accessions representing six species (B. napus, B. juncea, B. carinata, B. oleracea, B. nigra and B. rapa). The phenotypic data, assessed with an image analysis system, indicated that B. napus and B. oleracea have the most complex and largest root systems among the species evaluated, with relatively larger values for six of the eight traits measured. In contrast, B. nigra had the smallest root systems. The two species B. juncea and B. carinata shared comparable root system complexity and had thicker root systems compared with the other species. In addition, 313 of the Brassica accessions were genotyped using a 19K Brassica single nucleotide polymorphism (SNP) array. After removing monomorphic and low-coverage site markers, markers with a minor allele frequency (MAF) ≤ 0.05, and those missing data for > 5% of the accessions, a total of 6,213 SNP markers, comprising 5,103 markers on the A genome and 1,110 markers on the C genome, were selected for genome wide association studies (GWAS). These markers effectively covered genomic regions of 302.5 Mb for the A-genome and 452.8 Mb for the C-genome. Four mixed linear models (MLM), and two general linear models (GLM) were tested to identify the genomic regions and SNPs associated with the RSA traits. The GWAS identified 79 significant SNP markers associated with the eight root-related traits under investigation. These markers were distributed across the 18 chromosomes of B. napus, excluding chromosome C06. Sixty-five markers were located on the A-genome, while 14 were found on the C-genome. Furthermore, three specific genomic regions located on chromosomes A02, A03, and A06 were identified as hotspots containing genes associated with root traits. This work paves the way for additional research and exploration of these regions, offering new opportunities to deepen understanding of RSA traits and their genetic basis in the Brassicas.
Parameter Search Transfer Learning
Creators: Singamsetti, Mohan Sai
Publisher: name: University of Alberta Library
Year: 2023

Deep learning approaches have had success in many domains recently, particularly in domains with large amounts of training data. However, there are domains without a sufficient quantity of training data, or where the training data present is of insufficient quality. Transfer learning approaches can help in such low-data problems, but still tends to assume access to sufficient source domain data and a sufficient signal for transfer. In this work, we propose a novel approach for transfer learning called Parameter Search Transfer Learning (PSTL) which directly searches over parameters of a neural network in order to minimize the impact of low training samples in both source and target domains. Across Reinforcement Learning (RL), Regression, and Classification tasks we demonstrate that PSTL meets or exceeds the performance of transfer learning baselines, which we hypothesize is due to its ability to identify a better gradient.

description: Sample size calculations in clinical trials need to be based on profound parameter assumptions. Wrong parameter choices may lead to too small or too high sample sizes and can have severe ethical and economical consequences. Adaptive group sequential study designs are one solution to deal with planning uncertainties. Here, the sample size can be updated during an ongoing trial based on the observed interim effect. However, the observed interim effect is a random variable and thus does not necessarily correspond to the true effect. One way of dealing with the uncertainty related to this random variable is to include resampling elements in the recalculation strategy. In this paper, we focus on clinical trials with a normally distributed endpoint. We consider resampling of the observed interim test statistic and apply this principle to several established sample size recalculation approaches. The resulting recalculation rules are smoother than the original ones and thus the variability in sample size is lower. In particular, we found that some resampling approaches mimic a group sequential design. In general, incorporating resampling of the interim test statistic in existing sample size recalculation rules results in a substantial performance improvement with respect to a recently published conditional performance score.

Water and arsenic movement in Salix nigra under simulated  phytoremediation conditions
Creators: Perrault, Nicolas
Publisher: name: University of Alberta Library
Year: 2023

Arsenic is a highly toxic and ubiquitous element. To this day, millions of people are exposed to arsenic contamination, which poses global health concerns. Phytoextraction performed with willows, a form of phytoremediation, is a promising means of cleaning up soils containing hazardous levels of arsenic. Plant-water relations and cell transport activity both play key roles in this decontamination process, as they explain the movement of

hydrophilic contaminants from bulk soil into the plant. Both water and arsenic uptake, and their movement across cell membranes, are regulated by transport proteins. This thesis

studies the processes of arsenic and water transport in willows used in a phytoremediation context. Through two greenhouse experiments using a double-compartment design, physiological activity monitoring and mRNA profiling, we investigated the movement of water and arsenic in the soil and within willows under experimental treatments of drought and soil contamination. Our results show that a process of water redistribution towards dry surface soil occurs through Salix nigra root system, although aquaporins activity is repressed in surface roots exposed to drought. Based on mRNA profiles, we highlight the intricate willows’ root activity in response to both arsenic and drought at the gene expression level. The expression of aquaporins, phosphate transporters and ABC

transporters in roots identifies key genes responsible for water and arsenic transport under stress conditions. Their expression level indicates the presence of a weak exclusion

mechanism of arsenic in Salix nigra, allowing the easy uptake of the contaminant from deep soil. Simultaneously, the repression of aquaporin genes in surface roots blocks a

possible efflux pathway, confining the arsenic inside the plant. Most importantly, adverse growth conditions caused by contamination exposure and an extended episode of drought

in surface soil are more likely responsible for root decay, and induce the arsenic redistribution to surface soil layers. This process does not seem to result from the hydraulic redistribution observed in the short-term. This process should be considered in the planning of phytoremediation experiments in the field, either by trying to prevent it with proper irrigation, or by exploiting it in rotational cultures allowing the decontamination of deep and shallow soil in succession. The activity of transporter genes identified from the mRNA profiling results needs to be investigated with further testing to uncover their specific roles in arsenic transport, for example with heterologous expression systems. This knowledge could allow for the development of more efficient plants for decontamination purposes, through genetic engineering or genotypic selection of plants favoring contaminant transport.

description: In this paper, we present the development of the Altered States Database (ASDB), an open-science project based on a systematic literature review. The ASDB contains psychometric questionnaire data on subjective experiences of altered states of consciousness (ASC) induced by pharmacological and non-pharmacological methods. The systematic review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Scientific journal articles were identified through PubMed and Web of Science. We included studies that examined ASC using the following validated questionnaires: Altered States of Consciousness Rating Scale (APZ, 5D-ASC, 11-ASC), Phenomenology of Consciousness Inventory (PCI), Hallucinogen Rating Scale (HRS), or Mystical Experience Questionnaire (MEQ30). The systematic review resulted in the inclusion of a total of 165 journal articles, whereof questionnaire data was extracted and is now available on the Open Science Framework (OSF) website (https://osf.io/8mbru) and on the ASDB website (http://alteredstatesdb.org), where questionnaire data can be easily retrieved and visualized. This data allows the calculation of comparable psychometric values of ASC experiences and of dose-response relationships of substances inducing ASC.

description: An increased omega-3 polyunsaturated fatty acid (n-3 PUFA) tissue status can lead to a significant formation of anti-inflammatory lipid mediators and effective reduction in inflammation and tissue injury in murine colitis. Arachidonic acid lipoxygenases (ALOX) have been implicated in the pathogenesis of inflammatory bowel disease as well as in the formation of pro- and anti-inflammatory lipid mediators. To explore the role of Alox15 in the protective response found in fat1 transgenic mice with endogenously increased n-3 PUFA tissue status fat1 transgenic mice were crossed with Alox15-deficient animals and challenged in the dextran sulfate sodium (DSS)- and the 2,4,6-trinitrobenzene sulphonic acid (TNBS)-induced colitis model. Transgenic fat1 mice rich in endogenous n-3 PUFAs were protected from colitis. However, additional systemic inactivation of the Alox15 gene counteracted this protective effect. To explore the molecular basis for this effect Alox15 lipid metabolites derived from n-3 PUFA were analyzed in the different mice. Alox15 deficiency suppressed the formation of n-3 PUFA-derived 15-hydroxy eicosapentaenoic acid (15-HEPE). In contrast, treating mice with intraperitoneal injections of 15S-HEPE protected wild-type mice from DSS- and TNBS-induced colitis. These data suggest that the anti-colitis effect of increased n-3 PUFA in the transgenic fat1 mouse model is mediated in part via Alox15-derived 15-HEPE formation.

description: Graphene has been a subject of great interest in condensed matter physics due to its exotic topological properties. We have used an STM capable of individual atomic manipulation to engineer molecular graphene nanostructures which host relativistic massless Dirac fermions and constitute a fully-tunable electronic system. Motivated by this light-like behavior, our ultimate goal is to create a Veselago lens out of flakes of doped molecular graphene. This work explores the refraction of Dirac fermions across various types of molecular graphene junctions, including neutral-p, neutral-n, n-n, and neutral graphene - 2 dimensional electron system junctions. Principle to our analysis is a new technique combining the traditional quasi-particle interference method used in scanning tunneling microscopy with individual atomic manipulation, which allows us to investigate the scattering of electron wave functions in 2D systems with great precision. Finally, we also explore the possibility of ’tachyonic’ behavior of Dirac fermions as they refract across junctions from areas with higher to lower group velocities. We find significant evidence of refraction of Dirac fermions across various junctions, as well as propose a theoretical explanation for the angles of refraction based off of band structure. We also find evidence of ’tachyonic behavior’ in Dirac fermion refraction.

description: Until human infants are 4 or 5 months old, they are unable to reach for and grasp objects. But does this mean that young infants do not understand the reaching actions of other people? Over the past two decades, research on this topic has produced two seemingly contradictory findings. The first finding is that first-person experience with reaching via, ‘sticky mittens’ training, helps 3-month-olds to understand that people reach efficiently (Skerry et al., 2013) towards particular goal objects (Sommerville et al., 2005; Gerson & Woodward, 2014a, 2014b). The second finding is that 3-month-olds, under some conditions, are capable of understanding other people’s goals and costs without training (Liu et al., 2019; Luo, 2011; Choi et al., 2018; Choi et al., unpublished; Woo et al., unpublished). Here, I propose a unifying account of these findings: 3-month-old infants have the conceptual repertoire to appreciate other people’s goals and costs, and action training is one of many experimental regimes that help reveal what 3-month-olds know about action. Here, I review this past work, and also provide a quantitative analysis of the original data from this work, collected from 586 three-month-old infants. Using these data sources, I evaluate the hypothesis that 3-month-olds’ understanding of other people’s actions varies in accordance of the perceptual and representational demands of the tasks used to test their abilities, rather than hinging upon their first-person motor experience per se. I end by proposing an account of how young infants learn about other people’s minds and actions, and suggest key future studies that can test this account empirically. At present, I envision this paper as a review paper including a quantitative analysis of past data. This pre-registration document outlines the analysis plan for the quantitative portion of this paper.

description: The bone marrow microenvironment and adipocytes play a crucial role as growth mediators in the development of bone metastases. This study evaluated the growth and underlying pathophysiological processes of bone metastases in obese experimental animals using multiparametric MRI and PET/CT. A bone metastasis model was established in rats by inoculating breast cancer cells into the bone marrow of the hind limb. The animals were divided into four groups: one receiving a high-fat diet (HFD), another on a normal diet (ND), with and without lipid metabolism-inhibiting therapy (BADGE). Functional and metabolic parameters were assessed using MRI (DCE-MRI and DWI) and [18F]FDG-PET/CT on days 10, 20, and 30 post-tumor inoculation. DCE-MRI parameters (AUC) were significantly increased in the HFD group by day 30 compared to controls, while the Apparent Diffusion Coefficient (ADC) showed no significant differences between groups. The Standard Uptake Value (SUV) from [18F]FDG-PET/CT was significantly higher in the HFD metastases. BADGE treatment led to a significant reduction in AUC and SUV in HFD-fed animals compared to ND-fed controls. MRT and [18F]FDG-PET/CT revealed increased vascularization and glucose metabolism in bone metastases associated with obesity. This multimodal imaging approach offers valuable insights into the pathophysiology of bone metastases in obesity and opens new possibilities for therapy monitoring of bone metastases.

description: Adenine nucleotides represent crucial immunomodulators in the extracellular environment. The ectonucleotidases CD39 and CD73 are responsible for the sequential catabolism of ATP to adenosine via AMP, thus promoting an anti-inflammatory milieu induced by the "adenosine halo". AMPD2 intracellularly mediates AMP deamination to IMP, thereby both enhancing the degradation of inflammatory ATP and reducing the formation of anti-inflammatory adenosine. Here, we show that this enzyme is expressed on the surface of human immune cells and its predominance may modify inflammatory states by altering the extracellular milieu. Surface AMPD2 (eAMPD2) expression on monocytes was verified by immunoblot, surface biotinylation, mass spectrometry, and immunofluorescence microscopy. Flow cytometry revealed enhanced monocytic eAMPD2 expression after TLR stimulation. PBMCs from patients with rheumatoid arthritis displayed significantly higher levels of eAMPD2 expression compared with healthy controls. Furthermore, the product of AMPD2-IMP-exerted anti-inflammatory effects, while the levels of extracellular adenosine were not impaired by an increased eAMPD2 expression. In summary, our study identifies eAMPD2 as a novel regulator of the extracellular ATP-adenosine balance adding to the immunomodulatory CD39-CD73 system.

description: We consider a one-dimensional XX spin chain in a nonequilibrium setting with a Lindblad-type boundary driving. By calculating large deviation rate function in the thermodynamic limit, being a generalization of free energy to a nonequilibrium setting, we obtain a complete distribution of current, including closed expressions for lower-order cumulants. We also identify two phase-transition-like behaviors in either the thermodynamic limit, at which the current probability distribution becomes discontinuous, or, at maximal driving, when the range of possible current values changes discontinuously. In the thermodynamic limit the current has a finite upper and lower bound. We also explicitly confirm nonequilibrium fluctuation relation and show that the current distribution is the same under mapping of the coupling strength Gamma -> 1/Gamma.

On Supporting QUIC Data Transmission through Dynamic Multicast Management
Creators: name: Cleber Araujo
Publisher: name: Zenodo
Year: 2022

description: As Internet users progressively increase, latency, speed, and the mobility of nodes and connections have become significant concerns. In this dynamic scenario, Heterogeneous Networks predominate, in which communications occur between devices of different technologies, manufacturers, capacities, and structures. Most communications on these networks work through the TCP protocol, which wastes much of the resources available on networks and communications. Using some resources offered by QUIC, this research aims to investigate optimization methods of dynamic multicast connections in heterogeneous and multipath environments to provide an alternative to the current demands of computer networks and mitigate the current limitations existing in the current TCP architecture.

description: Centaurs are the transitional population between trans-Neptunian objects (TNOs) and Jupiter-family comets. For this reason it is possible to access the smaller ones, which is more difficult to do with the TNO population. The goal of this work is to characterize a set of 16 Centaurs in terms of their size, albedo, and thermal properties. We study the correlations, for a more extended sample obtained from the literature, of diameter, albedo, orbital parameters, and spectral slopes. We performed three-band photometric observations using Herschel-PACS and used a consistent method for the data reduction and aperture photometry of this sample to obtain monochromatic flux densities at 70, 100, and 160 $μ$m. Additionally, we used Spitzer-MIPS flux densities at 24 and 70 $μ$m when available. We also included in our Centaur sample scattered disk objects (SDOs), a dynamical family of TNOS, using results previously published by our team, and some Centaurs observed only with the Spitzer/MIPS instrument. We have determined new radiometric sizes and albedos of 16 Centaurs. The first conclusion is that the albedos of Centaur objects are not correlated with their orbital parameters. Similarly, there is no correlation between diameter and orbital parameters. Most of the objects in our sample are dark (pv < 7%) and most of them are small (D < 120km). However, there is no correlation between albedo and diameter, in particular for the group of the small objects as albedo values are homogeneously distributed between 4 to 16%. The correlation with the color of the objects showed that red objects are all small (mean diameter 65 km), while the gray ones span a wide range of sizes (mean diameter 120 km). Moreover, the gray objects tend to be darker, with a mean albedo of 5.6%, compared with a mean of 8.5% (ranging from 5 to 15%) for the red objects.
