Neoperla sassandrae

description: 40. Neoperla sassandrae n. sp.
(Figs. 217–221)
 Type material: holotype ♀ (NEOP343; Z19/91), 4 ♀ paratypes, République de Côte d'Ivoire: Sassandra R., Soubré [5.76, -6.60], light trap, M. Mühlenberg, 16.8.1970 (SMNS).
 Habitus. WL 10.5–11.5 mm. Yellow, a small light brown spot between the ocelli. Wings slightly turbid, veins brownish.
 Male. Unknown.
 Female (Figs. 217–219). S8 with a short transverse subgenital plate. The brown mark on S8 is large and deeply indented in front, caudally it is truncate. Mark sharply subdivided by a transverse pale streak. Vagina basally supported by sclerotised lateral folds, distally regularly rounded, top with distinct oblique folds which are very apparent along the sides. SSt densely scaly, only a short basal stretch bare on concave side. SSt about 4* as long as S8 and vagina. No spines in vagina but many delicate microtrichia caudally from insertion of SSt. Spermatheca coiled.
 Egg (Fig. 220–221). Slender, 352*180µm. About 20 straight striae, the bare costae are unusually narrow, the sulci exceptionally wide, with irregular punctures and unmodified micropyles. Operculum parabolic, smooth, punctation fine, unordered. Collar sessile, with 2 rings of cells, anchor cavity deep, anchor mushroom-shaped, with single solid stem.
 DNA (Figs. 491–492, 496). Only the female holotype from Ivory Coast was sequenced with the genome-skimming approach, obtaining 2,742bp of mitochondrial, protein-coding genes. The species is maximally supported (100/100/100) as being nested within N. burgeoni, and further molecular study with nuclear markers is needed to resolve this discrepancy between morphological and molecular characters.
 Notes. The status of N. sassandrae n. sp. as a separate species is doubtful. A reduction of the caudal of the three marks on female S8 is characteristic of the burgeoni -complex: in N. burgeoni it is absent and the caudal half of sternite is entirely pale, with straight caudal edge; in N. beta, the caudal mark is small to vestigial. The opposite occurs in N. sassandrae: S8 is covered by a brown mark with only a narrow pale slot in front of the distal part which extends onto the short subgenital plate. The lateral vaginal sclerites, the long SSt and especially the narrow egg costae are also characteristic. However, by DNA it is an early diverging taxon within N. burgeoni and not a distinct species.
 Etymology. The name is a noun in apposition in the genitive case referring to the upstream region of the river where the specimens were collected.

description: This thesis presents a comprehensive analysis of the interplay between forest fires and vegetation dynamics in Alberta, Canada, under the lens of climate change. By synthesizing data from remote sensing, climate records, and fire databases, the study reveals the intricate relationships between vegetation cover changes and climatic factors throughout 2001–2022. It highlights the significant lead and lag times between the Normalized Difference Vegetation Index (NDVI) and climate variables such as Land Surface Temperature (LST), relative humidity, and precipitation, offering insights into the temporal dynamics of vegetation response to climatic influences. The research further explores the patterns and trends of forest fires, correlating them with interpolated climate data across various subregions. Using trend analysis and anomaly detection methods, the study identifies significant warming and drying trends, alongside variable precipitation changes, which have influenced both human-caused and lightning-induced forest fires. The findings underscore the differential impact of climate variables on fire occurrence and source, with notable patterns emerging in subregions like Athabasca Plain and Central Mixedwood. Building on these insights, the thesis develops a robust forest fire spread model, validated through high-precision simulations of the 2011 Slave Lake and 2016 Fort McMurray wildfires. The model leverages regional physical features, climatic data, and MODIS datasets to offer accurate fire behavior predictions. The phased simulation approach adapts to dynamic factors such as weather conditions and firefighting strategies, enhancing the model's applicability for effective fire management. Ultimately, this thesis aims to bridge the gap between theoretical understanding and practical application, providing valuable contributions to Alberta's forest fire management and community protection strategies. The research paves the way for more informed decision-making in the face of climate change by offering a nuanced understanding of fire-vegetation-climate interactions and developing an advanced predictive model.

Decision support systems

description: Seasonal climate forecasts (SCFs) have received a lot of attention for climate risk management in agriculture. The question is, how can we use SCFs for informing decisions in agriculture? SCFs are provided in formats not so conducive for decision-making. The commonly issued tercile probabilities of most likely rainfall categories i.e., below normal (BN), near normal (NN) and above normal (AN), are not easy to translate into metrics useful for decision support. Linking SCF with crop models is one way that can produce useful information for supporting strategic and tactical decisions in crop production e.g., crop choices, management practices, insurance, etc. Here, we developed a decision support system (DSS) tool, Climate-Agriculture-Modeling and Decision Tool (CAMDT), that aims to facilitate translations of probabilistic SCFs to crop responses that can help decision makers adjust crop and water management practices that may improve outcomes given the expected climatic condition of the growing season.
Fear of childbirth among young Canadians

description: In my secondary analysis of a large online survey data set (n = 3,680 university students), I used both quantitative and qualitative data analysis techniques to better understand factors contributing to students’ fear of childbirth. Albert Bandura’s social learning theory served as my conceptual framework to guide the development of a 6-item fear of birth scale and my selection of covariates that may be associated with fear of birth among Canadian students. I triangulated themes inductively derived from comments about labour and birth (n=1337) written by female respondents who scored in the high and low range on the fear of birth scale with the quantitative results to improve understanding of the phenomenon. Fear of childbirth affected approximately 1 in 7 female students; very few male students exhibited fear of birth (< 4%). Concerns over physical changes during pregnancy and birth were strongly associated with Cesarean section (CS) preference among male and female students. Having learned about pregnancy and birth through the media was associated with higher fear scores, compared to other sources of information. When examining predictors of childbirth fear in a logistic regression model, I found two factors decreased fear of birth: increased confidence in students’ knowledge of pregnancy and birth and having witnessed a birth first hand. Qualitative themes extended my understanding of the fear of birth scores, by indicating that fear of pain is a dominant dimension of childbirth fear among female students. Obstetric interventions, such as elective CS, are favoured by students with high fear of birth, and seen as a way to circumvent the pain of childbirth. Women with high and low fear of birth supported the theme that mode of delivery is a woman’s choice; however, students with low fear of birth were more likely to view birth as a natural and normal process and express concerns that obstetric interventions may carry unacceptable risks. Comments from students with high fear of birth supported the themes that pain of childbirth is unmanageable and birth is a painful and frightening ordeal. Findings from my study have important implications for education, practice and research.
Reconsidering the Case for Tax Reform during a Crisis

Subjects: Taxation law

description: The impact of COVID-19 on fiscal systems worldwide is exactly the type of crisis thought necessary to precipitate major tax reform. This article contends that if Australia is about to embark on significant tax reform, then this must be accompanied by a full and frank account of the respective benefits and risks of reform. It uses the debate on Goods and Services Tax (‘GST’) reform to reveal the flaws inherent in existing reform discussions that fail to progress beyond the economic merits of a policy idea without sufficient regard to how those ideas are implemented (or not) in practice. The GST reform debate generally proceeds with supporters of GST reform arguing for the expansion of the tax on the grounds of economic efficiency and opponents of reform arguing against the expansion of the tax on the basis of unfairness. However, when the discussion moves beyond economic theory and takes account of how the GST operates in practice, and specifically the laws and legal institutions that implement the GST, many of the purported benefits of the GST do not hold up. This has important consequences for the types of reform proposals put forward as well as how those proposals are assessed.

description: Motivated by the recent LHC hints of a Higgs boson around 125 GeV, we assume a SM-like Higgs with the mass 123-127 GeV and study its implication in low energy SUSY by comparing the MSSM and NMSSM. We consider various experimental constraints at 2-sigma level (including the muon g-2 and the dark matter relic density) and perform a comprehensive scan over the parameter space of each model. Then in the parameter space which is allowed by current experimental constraints and also predicts a SM-like Higgs in 123-127 GeV, we examine the properties of the sensitive parameters (like the top squark mass and the trilinear coupling A_t) and calculate the rates of the di-photon signal and the VV^* (V=W,Z) signals at the LHC. Our typical findings are: (i) In the MSSM the top squark and A_t must be large and thus incur some fine-tuning, which can be much ameliorated in the NMSSM; (ii) In the MSSM a light stau is needed to enhance the di-photon rate of the SM-like Higgs to exceed its SM prediction, while in the NMSSM the di-photon rate can be readily enhanced in several ways; (iii) In the MSSM the signal rates of pp -> h -> VV^* at the LHC are never enhanced compared with their SM predictions, while in the NMSSM they may get enhanced significantly; (iv) A large part of the parameter space so far survived will be soon covered by the expected XENON100(2012) sensitivity (especially for the NMSSM).

description: The turbulent jet flames in fuel sprays are of a great importance and are used in many practical applications,e.g., aircraft and automotive direct fuel injection systems. In this work we analyse the process of spark ignition intwo-phase temporally evolving jet which carries the fuel spray. We focus on a dependence of the ignition on localflow structures, spark parameters and fuel droplets size. The fuel (n-Heptane) spray evaporates and mixes with theco-flowing oxidizer (air) creating a flammable mixture. The spark is modelled as a source term added to the energyequation. The goal of the research is to investigate the forced ignition and subsequent flame propagation/extinctionin the low Mach number turbulent flow.  The computations are carried out using Implicit Large Eddy Simulation(ILES) method by the high-order in-house LES solver. Liquid droplets are modelled in Lagrangian reference frameas point sources of mass, momentum and energy. The results show that combined effect of local fuel concentration,strain rate and scalar dissipation rate plays a main role in ignition. On the other hand, high rates of strain at thespark position cause substantial flame stretching leading to its extinction.

description: Modern cosmology relies on the assumption of large-scale isotropy and homogeneity of the Universe. However, locally the Universe is inhomogeneous and anisotropic. So, how can local measurements (at the 100 Mpc scale) be used to determine global cosmological parameters (defined at the 10 Gpc scale)? We use Buchert's averaging formalism and determine a set of locally averaged cosmological parameters in the context of the flat Lambda cold dark matter model. We calculate their ensemble means (i.e. their global values) and variances (i.e. their cosmic variances). We apply our results to typical survey geometries and focus on the study of the effects of local fluctuations of the curvature parameter. By this means we show, that in the linear regime cosmological backreaction and averaging can be reformulated as the issue of cosmic variance. The cosmic variance is found largest for the curvature parameter and discuss some of its consequences. We further propose to use the observed variance of cosmological parameters to measure the growth factor. [abbreviated]

description: Parvalbumin inhibitory interneurons (PV-INs) are a crucial subclass of cortical interneurons, essential for maintaining excitatory/inhibitory (E/I) balance. Disruptions in E/I balance can impair learning, memory, and normal brain function. PV-INs are particularly susceptible to various insults, potentially leading to pathological conditions such as schizophrenia, epilepsy, autism, and Alzheimer's disease. However, the role of PV-INs in these disorders is not fully understood. Our research has identified sex differences in the vulnerability of retrosplenial cortex (RSC) PV-INs under conditions like Alzheimer's disease, traumatic brain injury, and early life stress. This study aims to investigate sex differences in PV-IN characteristics under normal healthy condition—such as number, connectivity, and function—in the RSC of healthy mice, which may underlie differential vulnerability between sexes. Here, we found that both female and male mice exhibit similar RSC neuronal activity levels, indicating no impairment. However, female mice have fewer PV-INs compared to males, and their PV-INs are less frequently surrounded by protective perineuronal nets. Additionally, female PV-INs have more presynaptic contacts per cell than males. This suggests a compensatory mechanism in females, where lower PV-IN numbers with increased synaptic connections allow them to maintain equivalent levels of inhibition. This pattern indicates that despite fewer PV-INs, females may have adaptive advantages that mitigate the impact of reduced PV-IN numbers, contributing to their resilience against certain pathological conditions.

Tree-Structure Expectation Propagation for LDPC Decoding over the BEC

description: We present the tree-structure expectation propagation (Tree-EP) algorithm to decode low-density parity-check (LDPC) codes over discrete memoryless channels (DMCs). EP generalizes belief propagation (BP) in two ways. First, it can be used with any exponential family distribution over the cliques in the graph. Second, it can impose additional constraints on the marginal distributions. We use this second property to impose pair-wise marginal constraints over pairs of variables connected to a check node of the LDPC code's Tanner graph. Thanks to these additional constraints, the Tree-EP marginal estimates for each variable in the graph are more accurate than those provided by BP. We also reformulate the Tree-EP algorithm for the binary erasure channel (BEC) as a peeling-type algorithm (TEP) and we show that the algorithm has the same computational complexity as BP and it decodes a higher fraction of errors. We describe the TEP decoding process by a set of differential equations that represents the expected residual graph evolution as a function of the code parameters. The solution of these equations is used to predict the TEP decoder performance in both the asymptotic regime and the finite-length regime over the BEC. While the asymptotic threshold of the TEP decoder is the same as the BP decoder for regular and optimized codes, we propose a scaling law (SL) for finite-length LDPC codes, which accurately approximates the TEP improved performance and facilitates its optimization.

description: We consider transport through a vibrating molecular quantum dot contacted to macroscopic leads acting as charge reservoirs. In the equilibrium and nonequilibrium regime, we study the formation of a polaron-like transient state at the quantum dot for all ratios of the dot-lead coupling to the energy of the local phonon mode. We show that the polaronic renormalization of the dot-lead coupling is a possible mechanism for negative differential conductance. Moreover, the effective dot level follows one of the lead chemical potentials to enhance resonant transport, causing novel features in the inelastic tunneling signal. In the linear response regime, we investigate the impact of the electron-phonon interaction on the thermoelectrical properties of the quantum dot device.

Investigating the role of pericyte infection in Vesicular Stomatitis Virus stimulated immune activation

description: Oncolytic viruses (OVs) are a type of cancer immunotherapy. Although OVs’ exact mechanism of action remains to be elucidated, it is believed that they activate the immune system by selectively infecting and lysing tumor cells. Recent studies demonstrate that non-tumor cells in the tumor microenvironment (TME) may also assist in OV-mediated tumor clearance. We have observed that Vesicular Stomatitis Virus (VSV), an OV, infects pericytes in the TME of various murine tumor models. Pericytes are vascular mural cells that maintain blood vessel physiology and take part in the inflammatory response. Despite a lack of tumor cell infections in our model, VSV treatment facilitated tumor regression in a CD8+ T-cell dependent manner. Therefore, the overall aim of this project was to investigate if pericytes play in VSV-mediated anti-tumor action. An in vitro model, using human placental pericytes (HPCs), was created to characterize the transcriptional and translational profile of VSV-infected HPCs over time. Some of the topmost differentially expressed (DE) genes and proteins of VSV-infected HPCs comprise of chemokines (MIP-1β, IFNL1 and CXCL10) and surface markers involved in immune regulation (SIGLEC1, CD69 and ICAM1). Pathways related to chemokine activity and innate immune response were also found to be enriched in the transcriptome and proteome of VSV-infected HPCs. Since multiple chemokines were secreted by VSV-infected HPCs, we sought to determine the impact of contents released by VSV-infected HPCs i.e. conditioned media (VSV CM) on human dermal microvascular endothelial cells (HDMECs). The transcriptional and translational response of HDMECs was assessed by exposing them to UV-irradiated VSV CM or titer matched VSV diluted in control media (VSV CTL). The results indicate that the elements secreted by VSV-infected HPCs increase the immune cell recruitment potential of HDMECs. This is evidenced by the significantly increased expression of immune cell recruiting genes (CSF2, IL1B and CXCL3) and immune adhesion proteins (SELE and ICAM1) in HDMECs treated with VSV CM versus those exposed to VSV CTL. Overall, the results indicate that VSV-infected HPCs exhibit a phenotype that likely alerts the immune system. VSV-infected HPCs also release soluble factors that activate endothelial cells to potentially facilitate immune cell recruitment.

description: Background: The field of Pediatric Hospital Medicine (PHM) has grown considerably in North America over the last three decades in response to the increasing complexity and acuity of the pediatric in-patient population. Although PHM fellowship programs have been developed in Canada, no national competencies framework currently exists to guide curricular content. This study aimed to identify competencies required for the practice of PHM in Canada. Methods: Using Delphi methodology, a national panel of experts in PHM iteratively rated potential competencies, on a 5-point scale, to determine their priority for inclusion. Responses were analyzed after each round. Competencies that were assigned a rating of three or less by 80% or more of panelists were removed from subsequent rounds. The remaining competencies were re-sent to panelists for further ratings until consensus was reached, defined as Cronbach’s α ≥0.95 and after a minimum of two survey rounds. At the conclusion of the Delphi process, competencies where 80% or more of the panelists assigned a rating or four or higher were included. Results: Two rounds of the Delphi process were required to reach consensus. Thirty-five participants completed both survey rounds. The participants represented 13 Canadian pediatric tertiary care centers and five community hospitals. Of 176 initial competencies, 109 PHM competencies achieved consensus. Conclusion: This is the first study to define national competencies for PHM in Canada. The competencies identified provide a framework for PHM fellowship program directors to shape local curricula. The results may also be used to inform the development of comprehensive national PHM fellowship curricula.

description: Radon transform (RT) allows mapping different seismic events using different basis functions. Integrating RTs with machine learning (ML) presents an innovative approach to addressing non-linear problems in seismic data. By incorporating deep learning (DL) techniques into the framework, the objective is to address challenges encountered in seismic data processing, particularly in separating signal from coherent noise within the model space. A central idea of this work is the utilization of ML as an alternative to traditional sparseness techniques, which can struggle with complex and overlapping seismic events. Through a pixel-by-pixel approach, ML-based approaches leverage DL's capability to discern non-linear patterns in images, enabling effective segregation of multiples and ground roll from reflections in the RT domain. This approach becomes particularly valuable in scenarios where achieving complete spatial separation is challenging, for example, in multiple or ground roll overlapping primary reflections. This study conducts numerical experiments to assess the U-Net's effectiveness in discerning ground roll and multiples, employing various workflows to predict RT panels and maximizing RT utility by incorporating multiple channels of information like RGB colour channels in an image. Experiments examined the efficiency of different RT types, such as Hyperbolic RT (HRT) and Parabolic RT (PRT), for training a U-Net model to predict multiples. While U-Net partly succeeded in predicting multiples and highlighting the importance of label selection, it also faced challenges. Transform artifacts linked to input geometry, like truncation and sampling, hampered inference, lowering generalization. Furthermore, tests deploying a Hybrid Linear-Parabolic RT methodology for ground roll suppression in a field dataset helped analyze crosstalk problems between different RT spaces. Different channels provided insights into the leakage of ground roll among the RT used, with the three-channel approach showing promising results to forecast ground roll attenuated RT panels but challenges persisting in fully disentangling ground roll from reflection data. Continued research efforts are crucial to address these challenges and unlock the full potential of ML with seismic.

description: We consider stochastic dynamical systems defined by differential equations with a uniform random time delay. The latter equations are shown to be equivalent to deterministic higher-order differential equations: for an $n$-th order equation with random delay, the corresponding deterministic equation has order $n+1$. We analyze various examples of dynamical systems of this kind, and find a number of unusual behaviors. For instance, for the harmonic oscillator with random delay, the energy grows as $\exp((3/2)\,t^{2/3})$ in reduced units. We then investigate the effect of introducing a discrete time step $ε$. At variance with the continuous situation, the discrete random recursion relations thus obtained have intrinsic fluctuations. The crossover between the fluctuating discrete problem and the deterministic continuous one as $ε$ goes to zero is studied in detail on the example of a first-order linear differential equation.

description: A slope $\frac pq$ is called a characterizing slope for a given knot $K_0$ in $S^3$ if whenever the $\frac pq$-surgery on a knot $K$ in $S^3$ is homeomorphic to the $\frac pq$-surgery on $K_0$ via an orientation preserving homeomorphism, then $K=K_0$. In this paper we try to find characterizing slopes for torus knots $T_{r,s}$. We show that any slope $\frac pq$ which is larger than the number $\frac{30(r^2-1)(s^2-1)}{67}$ is a characterizing slope for $T_{r,s}$. The proof uses Heegaard Floer homology and Agol--Lackenby's 6--Theorem. In the case of $T_{5,2}$, we obtain more specific information about its set of characterizing slopes by applying more Heegaard Floer homology techniques.
description: Version 2: 19 pages. This is a major revision. The title of the first version was "Towards a Dehn surgery characterization of $T_{5,2}$". We extended the result in the first version to general torus knots. We also fixed a gap in the first version, so our result for $T_{5,2}$ is slightly weaker than the originally claimed one

description: Spinal cord injuries (SCI) are one of the most physically and psychologically devastating injuries one can survive. Despite decades of intense research effort, robust therapeutic treatment for this catastrophic condition remains elusive. The nature of the sequelae of SCI is characterized by progressive cell death in the injury penumbra, resulting in further neurological impairments. The intricate relationship between the vascular and nervous systems has become increasingly evident in many aspects of both normal physiology, and various pathological conditions, including SCI. Vascular abnormalities play a central role in the propagation of secondary damage after SCI. The aim of this thesis is to further the understanding of the vascular changes that occur after acute SCI. The endogenous expression of three angiogenic proteins: Angiopoietin-1 (Ang1), Angiopoietin-2 (Ang2) and Angiogenin will be examined after acute traumatic SCI. In the first study, the concentration of these proteins will be measured in a temporal series of cerebrospinal fluid (CSF) samples after human SCI. In the second study, the relative protein expression of Ang1 and Ang2 will be characterized in rat spinal cord after SCI. In human, Ang1 in CSF is not significantly different from non-SCI values after the initial spike at 24 hours post-SCI. Ang2 in CSF shows a delayed but persistent increase through the first 5 days post-SCI. In contrast, Ang1 in rat spinal cord decreases as early as 2 hours post-SCI, while low molecular weight Ang2 increases dramatically after SCI, from 2 hours to 3 days post-injury, peaking with a 13-fold elevation at 24 hours post-injury. These findings represent the first description of these proteins in the acute SCI setting in human CSF and rat spinal cord. The sustained elevation of Ang2 illustrates a possible mechanism by which reported vascular dysfunction and increases in blood-spinal cord-barrier (BSCB) permeability occurs after SCI. The patterns of change reported between the two studies may allude to the feasibility of using CSF as a biological proxy to future investigations into the biochemical events which occur in the spinal cord after SCI, and guide the development of pharmacologic treatments for this devastating condition.

(Fig. 222)
 Holotype ♀: Republic of Guinea, riv. Léleko affluent Milo près de Kousankoro [Conakry-Kousankoro, 9.538N, -13.677], 11.3.88 (Z16.50; NEOP159; SMNS, gift J. M. Élouard).
 Habitus. WL 13.0mm.
 Male. Unknown.
 Female. S8 with minimal transverse projection in middle of caudal margin. Sternite with a triangle of three light brown marks, the anterior marks large, the distal one elongate. Vagina with patches of small spines laterally from SSt attachment. SSt about 11* as long as S8, narrow over entire length, densely coated with scales, except in a short basal section.
 Egg (Fig. 222). Oval, 377*212µm (n=3). Anchor pole a little narrower than operculum which is broadly rounded, blunt, covered by shallow cells. The bare costae and the irregularly punctate sulci of the ≥ 25 straight striae are of similar width, the micropyles are freely visible. The collar is sessile and not set off against the egg contour, with a bare edge distally from the ring of low cells. The mushroom-shaped anchor with entire stem rises from a deep cavity.
 DNA (Figs. 491–492, 496). Only the female holotype from Guinea was sequenced with the genome-skimming approach, obtaining 10,965bp of mitochondrial, protein-coding genes. The species is very strongly supported (92.3/100/100) as sister to a maximally supported (100/100/100) group that comprises N. spironema n. sp., N. filamentosa n. sp., and N. orthonema n. sp..
 Notes. The holotype has no outstanding or unique morphological traits and was regarded as an unusual specimen of N. burgeoni or N. beta until molecular evidence suggested the present status.
 Many Plecoptera nymphs contain worm cysts, mainly in the abdominal fat body, the present specimen had many of them. They probably are Nematomorpha whose minute egg larvae bore into water insects and form cysts that infect terrestrial consumers in which the adult worm develops (Schmidt-Rhaesa 1997, Westheide & Rieger 1996). Occurrence in Plecoptera hosts was documented by Winterbourn (2005), during dissections we noticed them in several Neoperla specimens.
 Etymology. Named for Stephen Bent (CSIRO), in recognition of his support with data assemblies and annotations.

Unramified cohomology, $\A^1$-connectedness, and Chevalley-Warning problem in Grothendieck ring

description: We study the Chevalley-Warning problem in the Grothendieck ring $K_0(Var/k)$. We show that the $\A^1$-homotopy theory yields well defined invariants on $K_0(Var/k)/\bold{L}$, in particular the Brauer group is such an invariant. We use this to give a concrete counter-example to the Chevalley-Warning conjecture over a $C_1$-field (Brown and Schnetz, 2011). This also gives a negative answer to the question in Bilgin (2011).

description: Staphylococcus aureus (SA) pneumonia infections are widespread in Canada, particularly in hospitalized patients, and are associated with high mortality rates and significant financial costs to the healthcare system. A major limitation in our ability to design treatments to alleviate disease burden is a lack of understanding regarding how the lung’s frontline defenders, such as alveolar macrophages, interact with SA bacteria in humans. Unfortunately, there are a lack of models which accurately model human alveolar macrophages (AMs). To address this, we have designed a human lung on chip (LoC) device to improve human AM phenotypic differentiation in culture to investigate the interactions of SA with AMs. First, we used Mass Cytometry (CyTOF) to characterize the surface marker expression of PBMC-derived AMs cultured in the LoC device for three days. Results demonstrated PBMC-AMs acquired expression of numerous AM markers (eg. CD11b, CD169, CD206, and CD163) to similar levels as primary AMs derived from bronchoscopy samples. Next, we characterized PBMC-derived AM behavior in the LoC and their influence on LoC tissue morphology and barrier function. Results showed PBMC-AMs had similar migratory behaviors and morphology to what has been previously reported in vivo further validating our model. Subsequently, we examined the impact of bacterial infection using a 4-hour incubation with SA and found dramatically altered AM phenotype including altered marker expression and reduced migration. Finally, we incubated various strains and knockouts of SA in the LoC +/- PBMCs and found differing rates of bacterial abundance. Overall, we anticipate our model will offer an avenue for future studies seeking to understand human lung disease, particularly as it relates to SA lung infection.
Search for the Standard Model Higgs boson in the diphoton decay channel with 4.9 fb-1 of pp collisions at sqrt(s) = 7 TeV with ATLAS
Creators: name: ATLAS Collaboration

description: A search for the Standard Model Higgs boson is performed in the diphoton decay channel. The data used corresponds to an integrated luminosity of 4.9 fb-1 collected with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a center-of-mass energy of sqrt(s) = 7 TeV. In the diphoton mass range 110-150 GeV, the largest excess with respect to the background-only hypothesis is observed at 126.5 GeV, with a local significance of 2.8 standard deviations. Taking the look-elsewhere effect into account in the range 110-150 GeV, this significance becomes 1.5 standard deviations. The Standard Model Higgs boson is excluded at 95% confidence level in the mass ranges of 113-115 GeV and 134.5-136 GeV.

Popular Visual Images and the (Mis)Reading of Black Male Youth: a case for racial literacy in urban preservice teacher education

description: In the majority of public schools across the nation, Black male youth are undergoing what can be deemed as “educational genocide” – the killing off of any chances for an equitable education. This dramatically decreases opportunities for Black male youth to develop into fully participating citizens in a democratic society. In many ways, race is the silent killer because it is frequently masked. Preservice teachers often take their cue for how to treat Black male students from existing stereotypes about Black males and media representations of them. In this article, we argue for the development of racial literacy in preservice teacher education programs as a pedagogical method to mitigate the misreading of Black male students in teacher candidates’ fieldwork experiences and subsequently in their future classrooms. Our argument operates from the premise that in a time when diversity, multiculturalism, and inclusion are more widely recognized than ever before, the notion of race, and popular education films that depict race, still influence how teacher candidates view Black male students, and race remains a predictor for how these students experience school.
