description: Myelin allows for the rapid conduction of electrical impulses along axons. The breakdown of myelin can have debilitating consequences reflected in diseases such as multiple sclerosis (MS), in which severe demyelination leads to numerous neurological impairments. Strategies to enhance the remyelinating capacity of the myelinating cells, the oligodendrocytes (OLs), are being investigated with the hope of bringing to a halt the demyelinating process. Myelin formation begins with the extension of OL processes to contact axons. Proteolytic activity has been suggested to play a role for OL process extension and this event was suggested to be mediated in part by matrix metalloproteinases (MMPs), and in particular MMP-9. In an attempt to extend these findings, it was hypothesized that MMP-9 activity might also be important in remyelination where the myelinating program is re­initiated after injury. An impaired ability to remyelinate was observed in mice deficient for MMP-9. However, the mechanisms of action did not directly involve process extension but rather a need for MMP-9 to remove proteoglycans that are inhibitory for OL maturation. To elucidate whether other MMP members could also have important functions in OL biology studies on OLs and OL progenitor cells were performed. Purified OL showed high expression of MMP-12 and subsequent experiments revealed that MMP-12 played a role in OL process extension and OL maturation in culture. Finally, it was hypothesized that a deficiency of both MMP-9 and -12 would affect the coordinated developmental myelination and OL biology in vivo. Indeed, these studies showed a transient delay in overall developmental myelination, which was correlated to an excess production of insulin growth factor binding protein-6 (IGFBP-6). This molecule can, by reducing the bioavailability of insulin-like growth factor, act as a negative factor for myelination. Altogether, these data suggest that MMPs are important in controlling the levels of IGFBPs in the environment and thereby regulate the levels of insulin-like growth factor and myelination. Overall, this thesis has uncovered a beneficial mechanism of MMP-9 actions following a demyelinating insult in mice. Furthermore, MMP-12 was implicated in OL biology both in process extension and maturation of these cells. Finally, these proteolytic molecules were found important in the normal timing of initial developmental myelination probably through regulating levels of IGFBPs.

description: Bibliography: p. 63-68
description: The present study examined the relationship between bullying and social skills in a sample of 120 students in grades 4 through 6. A total of 14 teachers completed questionnaires about their students to determine (1) the relationship between two forms of bullying (i.e., direct physical bullying and indirect bullying) and social skills (i.e., cooperation, assertion, and self-control), and (2) gender differences in the relationship between the two forms of bullying and social skills. A series of partial correlation analyses were performed. Results revealed a significant relationship between direct physical bullying and social skills (r = -.46 p < .001), and indirect bullying and social skills (r = -.26 p < .01). Furthermore, the relationship between bullying and social skills differed according to gender. These combined results suggest that children who bully others, regardless of the form of bullying, are not likely to possess well-developed social skills to effectively manage interpersonal relationships.

description: We collected multiband imaging and spectroscopy for two fossil groups (RX J1119.7+2126 and 1RXS J235814.4+150524) and one normal group (NGC 6034). We computed photometric redshifts in the central zones of each group, combining previous data with the SDSS five-band data. For each group we investigated the red sequence (RS) of the color-magnitude relation and computed the luminosity functions, stellar population ages and distributions of the group members. Spectroscopy allowed us to investigate the large-scale surroundings of these groups and the substructure levels in 1RXS J235814.4+150524 and NGC 6034. The large-scale environment of 1RXS J235814.4+150524 is poor, though its galaxy density map shows a clear signature of the surrounding cosmic web. RX J1119.7+2126 appears to be very isolated, while the cosmic environment of NGC 6034 is very rich. At the group scale, 1RXS J235814.4+150524 shows no substructure. Galaxies with recent stellar populations seem preferentially located in the group outskirts. A RS is discernable for all three groups in a color-magnitude diagram. The luminosity functions based on photometric redshift selection and on statistical background subtraction have comparable shapes, and agree with the few points obtained from spectroscopic redshifts. These luminosity functions show the expected dip between first and second brightest galaxies for the fossil groups only. Their shape is also regular and relatively flat at faint magnitudes down to the completeness level for RX J1119.7+2126 and NGC 6034, while there is a clear lack of faint galaxies for 1RXS J235814.4+150524. RX J1119.7+2126 is definitely classified as a fossil group; 1RXS J235814.4+150524 also has properties very close to those of a fossil group, while we confirm that NGC 6034 is a normal group.

description: The fluctuations in the elastic light scattering spectra of normal and dysplastic human cervical tissues analyzed through wavelet transform based techniques reveal clear signatures of self-similar behavior in the spectral fluctuations. Significant differences in the power law behavior ascertained through the scaling exponent was observed in these tissues. The strong dependence of the elastic light scattering on the size distribution of the scatterers manifests in the angular variation of the scaling exponent. Interestingly, the spectral fluctuations in both these tissues showed multi-fractality (non-stationarity in fluctuations), the degree of multi-fractality being marginally higher in the case of dysplastic tissues. These findings using the multi-resolution analysis capability of the discrete wavelet transform can contribute to the recent surge in the exploration for non-invasive optical tools for pre-cancer detection.

description: In this letter we compute stringent astrophysical and cosmological constraints on a recently proposed Eddington-inspired Born-Infeld theory of gravity. We find, using a generalized version of the Zel'dovich approximation, that in this theory a pressureless cold dark matter fluid has a non-zero effective sound speed. We compute the corresponding effective Jeans length and show that it is approximately equal to the fundamental length of the theory $R_*=κ^{1/2} G^{-1/2}$, where $κ$ is the only additional parameter of theory with respect to general relativity and $G$ is the gravitational constant. This scale determines the minimum size of compact objects which are held together by gravity. We also estimate the critical mass above which pressureless compact objects are unstable to colapse into a black hole, showing that it is approximately equal to the fundamental mass $M_* = κ^{1/2} c^2 G^{-3/2}$, and we show that the maximum density attainable inside stable compact stars is roughly equal to the fundamental density $ρ_*=κ^{-1} c^2$, where $c$ is the speed of light in vacuum. We find that the mere existence of astrophysical objects of size $R$ which are held together by their own gravity leads to the constraint $κ< G R^2$. In the case of neutron stars this implies that $κ< 10^{-2} \, {\rm m^5 \, kg^{-1} \, s^{-2}}$, a limit which is stronger by about 10 orders of magnitude than big bang nucleosynthesis constraints and by more than 7 orders of magnitude than solar constraints.

description: Bibliography: p. 158-182

description: In astrocytes, calcium signaling represents a central mechanism for the integration of cellular activity, as it constitutes their principal way of intercellular communication and it mediates neurotransmitter release that will in turn modulate synaptic activity. Calcium homeostasis is therefore of fundamental importance, and the identification of the different pathways mediating calcium influx in astrocytes should constitute a focal area of investigation. While some components mediating calcium influx in astrocytes have already been thoroughly described, evidence regarding the expression of voltage-gated calcium channels in astrocytes is still limited and controversial. Since these channels are involved in many critical functions like exocytosis and the activation of multiple intracellular cascades, their investigation will bring essential insight to the physiology of astrocytes. The objective of this work was then to characterize voltage-gated calcium channel expression in astrocytes and to evaluate their regulation in malignant astrocytes. I described, using primarily molecular and biochemical techniques, voltage-gated calcium channels in astrocytes and T-type channels in glioma and characterized, with an expression system, the functional properties of two calcium channel splice variants that I have identified in these cells. I demonstrated that astrocytes express both high and low voltage-activated calcium channels and that the expression of T-type channels is regulated in glioma. I discovered that astrocytes express an R-type splice variant, previously identified in endocrine cells, and that human glioma express a novel T-type channel isoform that had not yet been observed in humans. I also discovered that annexin III associates specifically with the III-IV linker of this novel T-type isoform. Overall, these results show that astrocytes express different types of calcium channels and that T- type channels are differentially regulated in malignant astrocytes, suggesting the possibility that calcium channels significantly contribute to calcium signaling in astrocytes and that they are involved in the transformation of astrocytes into a malignant phenotype.

description: Complete electroweak two-loop corrections to the process $gg \to H$ are presented and discussed in a Standard Model with a fourth generation of heavy fermions. The latter is studied at the LHC to put exclusion limits on a fourth generation of heavy fermions. Therefore also a precise knowledge of the electroweak(EW) next-to-leading-order(NLO) corrections is important. The corrections due to the fourth generation are positive and large for a light Higgs boson, positive but relatively small around the $\bar{t}-t$ threshold and start to become negative for a Higgs boson mass around $M_H = 450 GeV$. Increasing further the value of the Higgs boson mass, the EW NLO effects tend to become huge and negative, ${\cal O}(-100%)$, around the heavy-fermion threshold, assumed at $1.2 TeV$, so that $gg$-fusion becomes non-perturbative. Above that threshold they start to grow again and become positive around $M_H= 1.75 TeV$. The behaviour at even larger values of $M_H$ shows a positive enhancement, ${\cal O}(+100%)$ at $M_H= 3 TeV$.

Social norms and the expression of culturally acceptable and unacceptable stereotypes
Creators: name: Lawson, Andrea
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 60-68
description: The present study assessed (a) the normative acceptability of expressing negative and positive perceptions of Canadians and Americans; (b) the relationship between this acceptability and degree of expression of these perceptions; (c) whether Canadian views of Americans can be shifted by exposure to contrasting consensus information; and (d) whether the magnitude of this shift is moderated by four individual difference variables. Perceptions of both groups and individual difference variables were assessed in the first of two experimental sessions. In the second session, shifts in perceptions of Americans were examined following the presentation of fabricated consensus information that indicated others held different beliefs about Americans than originally estimated. Correlational and experimental results indicated that people express a particular view of a particular group based on how much that view is perceived to be normative. The individual difference variables did not moderate shifts in this view. The implications of the role of social norms in the expression of acceptable and unacceptable stereotypes and prejudice are discussed.

description: In this paper we give a review of the method of imsets introduced by Studeny (2005) from a geometric point of view. Elementary imsets span a polyhedral cone and its dual cone is the cone of supermodular functions. We review basic facts on the structure of these cones. Then we derive some new results on the following topics: i) extreme rays of the cone of standardized supermodular functions, ii) faces of the cones, iii) small relations among elementary imsets, and iv) some computational results on Markov basis for the toric ideal defined by elementary imsets.

description: Under which conditions do citizens favor immediate policy implementation over delayed policy action? So far, studies assessing long-term policy issues like climate or social policy mostly focused on distributional consequences of policy implementation today but the implications of cost-benefit distributions over time remain underexplored. We argue that short-term cost distributions among citizens determine the extent to which citizens can prioritize the cost implications of delayed policy actions for the future in their preference formation process. Building on Switzerland's newly enacted climate policy that emphasizes the scale-up of carbon removal as a response to delayed climate policy intervention we field a survey experiment in the Swiss Environmental Panel (aimed N = approx. 3000). By doing so, we examine how citizens engage with the intergenerational burden-sharing challenges of climate policy strategies involving carbon dioxide removal. Respondents receive information on personalized cost implications of greenhouse gas reduction measures based on their carbon footprint. To dissect the implications of intergenerational cost allocations, half of the respondents will receive information about the costs of delaying climate change mitigation for the next generation. Following this, they are tasked with choosing how much greenhouse gas reduction and carbon removal they want Switzerland to pursue between 2025 and 2050. This approach enables us to assess how the intersection between personal and intergenerational cost distributions shapes support for delaying the implementation of potential high-cost policies.

We construct very effective near-cloaking structures for the scattering problem at a fixed frequency. These new structures are, before using the transformation optics, layered structures and are designed so that their first scattering coefficients vanish. Inside the cloaking region, any target has near-zero scattering cross section for a band of frequencies. We analytically show that our new construction significantly enhances the cloaking effect for the Helmholtz equation.

description: Abstract 
This study delves into the intricate relationship between embodied cognition and metaphorical discourse from a phenomenological standpoint. Metaphor, as a fundamental aspect of human language and thought, often relies on the body's experiential and sensorimotor dimensions to convey abstract concepts. From a phenomenological perspective, this study explores how individuals engage in metaphorical thinking, drawing on their embodied experiences and sensory perceptions to make sense of the world. A series of empirical studies demonstrate how metaphors are cognitive tools and embodied and enactive processes. The study explores the neural underpinnings of metaphor processing and highlights the role of the body in grounding abstract concepts in concrete experiences. Additionally, it investigates the cultural and contextual variations in metaphorical discourse, shedding light on the dynamic nature of embodied cognition within different socio-cultural settings. Furthermore, this study examines the implications of our findings for fields such as education, communication, and psychology. Understanding the embodied nature of metaphorical discourse can lead to more effective teaching strategies, improved cross-cultural communication, and enhanced therapeutic interventions. By appreciating how the body shapes our metaphorical expressions and interpretations, we can gain deeper insights into the human mind and its connection to language and meaning. In conclusion, this study advances our understanding of the intricate relationship between embodied cognition and metaphorical discourse from a phenomenological perspective. It underscores the importance of recognizing the role of the body in shaping our conceptualizations of the world, shedding new light on the fundamental processes that underlie human language and thought.

description: When combined with graphene, hexagonal boron nitride (h-BN) is an ideal substrate and gate dielectric with which to build metalh-BN|graphene field-effect devices. We use first-principles density functional theory (DFT) calculations for Cu|h-BN|graphene stacks to study how the graphene doping depends on the thickness of the h-BN layer and on a potential difference applied between Cu and graphene. We develop an analytical model that describes the doping very well, allowing us to identify the key parameters that govern the device behaviour. A predicted intrinsic doping of graphene is particularly prominent for ultrathin h-BN layers and should be observable in experiment. It is dominated by novel interface terms that we evaluate from DFT calculations for the individual materials and for interfaces between h-BN and Cu or graphene.

description: During its lifetime, the Far Ultraviolet Spectroscopic Explorer (FUSE) was used to observe 99 cataclysmic variables in 211 separate observations. Here, we present a survey of the moderate resolution (R\simeq10,000), far-ultraviolet (905 - 1188 °A), time-averaged FUSE spectra of cataclysmic variables (CVs). The FUSE spectra are morphologically diverse. They show contributions from the accretion disk, the disk chromosphere, disk outflows, and the white dwarf, but the relative contribution of each component varies widely as a function of CV subtype, orbital period and evolutionary state, inclination, mass accretion rate, and magnetic field strength of the white dwarf. The data reveal information about the structure, temperature, density and mass flow rates of the disk and disk winds, the temperature of the white dwarf and the effects of ongoing accretion on its structure, and the long-term response of the systems to disk outbursts. The complete atlas of time-averaged FUSE spectra of CVs are available at the Multimission Archive at Space Telescope Science Institute as a High Level Science Product.

description: We report on residual gas damping of the motion of a macroscopic test mass enclosed in a nearby housing in the molecular flow regime. The damping coefficient, and thus the associated thermal force noise, is found to increase significantly when the distance between test mass and surrounding walls is smaller than the test mass itself. The effect has been investigated with two torsion pendulums of different geometry and has been modelled in a numerical simulation whose predictions are in good agreement with the measurements. Relevant to a wide variety of small-force experiments, the residual-gas force noise power for the test masses in the LISA gravitational wave observatory is roughly a factor 15 larger than in an infinite gas volume, though still compatible with the target acceleration noise of 3 fm s^-2 Hz^-1/2 at the foreseen pressure below 10^-6 Pa.

description: Hadron production and their suppression in Pb+Pb collisions at LHC at a center-of-mass energy of s_NN = 2.76 TeV are studied within a multiphase transport (AMPT) model whose initial conditions are obtained from the recently updated HIJING 2.0 model. The centrality dependence of charged hadron multiplicity dN_ch/deta at midrapidity was found quite sensitive to the largely uncertain gluon shadowing parameter s_g that determines the nuclear modification of the gluon distribution. We find final-state parton scatterings reduce considerably hadron yield at midrapidity and enforces a smaller gluon shadowing to be consistent with dN_ch/deta data at LHC. With such a constrained parton shadowing, charged hadron and neutral pion production over a wide transverse momenta range are investigated in AMPT. Relative to nucleon-nucleon collisions, the particle yield in central heavy ion collisions is suppressed due to parton energy loss. While the calculated magnitude and pattern of suppression is found consistent with that measured in Au+Au collisions at s_NN = 0.2 TeV at RHIC, at the LHC energy the suppression is overpredicted which may imply the medium formed at LHC is less opaque than expected from simple RHIC extrapolations. Reduction of the QCD coupling constant alpha_s by ~30% in the higher temperature plasma formed at LHC as compared to that at RHIC was found to reproduce the measured suppression at LHC.

description: Introduction Incidence of stroke in Malaysian young adult is rising. The aims of this study were to estimate the proportion of stroke severity and to determine the factors associated with the stroke severity among young adult stroke patients. Method This was a cross-sectional study of young stroke patients aged between 18-49 years old. Data of patients registered from January 2014 to December 2018 with the first stroke event including socio demographic characteristics, stroke subtype classification, comorbidities characteristics, and other risk factors were retrieved from the National Neurology Registry (NNeur). The stroke severity outcome was measured with NIH stroke scale (NIHSS) and categorized as mild, moderate, or severe. Ordinal logistic regression was used to analyze and quantify the odds ratio and 95% confidence interval. Results A total of 1,421 patients with a mean age of 41±7.64 years old were analysed. The overall proportion of young adult stroke patients was 6.22% and predominantly by male with a ratio of 1.7 to 1. The proportion of mild, moderate and severe were 50.4% (95% CI:0.48,0.54), 41.2% (95% CI:0.38,0.44) and 8.7% (95% CI:0.07,0.10), respectively. In multivariable analysis, ischaemic stroke (OR=2.15, 95% CI:1.43,3.23), atrial fibrillation (OR=3.94, 95% CI:2.08,7.47) and alcohol drinking (OR=1.93, 95% CI:1.06,3.50) were factors that influenced higher odds of having a more severe stroke. Conclusion Of total, about 50% of young adult patient was categorized as mild stroke. Stroke classification, atrial fibrillation and alcohol drinking were factors that influenced in having a more severe stroke.

description: Recent studies have suggested that the Nuclear Pore Complex (NPC) plays a significant role in mechanotransduction. When a force is exerted, the NPC's diameter widens, leading to an increased molecular flux into the nucleus. In this study, we sought to further explore this phenomenon and quantitativelly assess the impact of pore dilation on molecular transport through the NPC. Utilizing the scaling theory of polymers, we developed a theoretical model to examine the relationship between pore size and the molecular transport rate. Our model posits that the mesh structure inside the pore, formed by FG-Nups, significantly influences the transport rate. Consequently, we propose that the transport rate is exponentially related to the pore size. To validate our model, we conducted extensive Brownian dynamics simulations. Our results demonstrated that the model accurately represents the transport dynamics except for exceptionally small molecules. For these molecules, the local mesh structure becomes less significant, and instead, they perceive the global structure of the pore. We also identified a critical threshold value, which allows for an estimation of whether a given molecule falls within the scope of our model. Our findings provide valuable insights into the dynamics of molecular transport in the NPC and pave the way for future research on the NPC's role in mechanotransduction.

description: We present the orbital and physical parameters of a newly discovered low-mass detached eclipsing binary from the All-Sky Automated Survey (ASAS) database: ASAS J011328-3821.1 A - a member of a visual binary system with the secondary component separated by about 1.4 seconds of arc. The radial velocities were calculated from the high-resolution spectra obtained with the 1.9-m Radcliffe/GIRAFFE, 3.9-m AAT/UCLES and 3.0-m Shane/HamSpec telescopes/spectrographs on the basis of the TODCOR technique and positions of H_alpha emission lines. For the analysis we used V and I band photometry obtained with the 1.0-m Elizabeth and robotic 0.41-m PROMPT telescopes, supplemented with the publicly available ASAS light curve of the system. We found that ASAS J011328-3821.1 A is composed of two late-type dwarfs having masses of M_1 = 0.612 +/- 0.030 M_sun, M_2 = 0.445 +/- 0.019 M_sun and radii of R_1 = 0.596 +/- 0.020 R_sun, R_2 = 0.445 +/- 0.024 R_sun, both show a substantial level of activity, which manifests in strong H_alpha and H_beta emission and the presence of cool spots. The influence of the third light on the eclipsing pair properties was also evaluated and the photometric properties of the component B were derived. Comparison with several popular stellar evolution models shows that the system is on its main sequence evolution stage and probably is more metal rich than the Sun. We also found several clues which suggest that the component B itself is a binary composed of two nearly identical ~0.5 M_sun stars.

description: Axisymmetric MHD simulations are used to investigate the Bondi-Hoyle accretion onto an isolated magnetized neutron star moving supersonically (with Mach number of 3) through the interstellar medium. The star is assumed to have a dipole magnetic field aligned with its motion and a magnetospheric radius R_m less then the accretion radius R_BH, so that the gravitational focusing is important. We find that the accretion rate to a magnetized star is smaller than that to a non-magnetized star for the parameters considered. Close to the star the accreting matter falls to the star's surface along the magnetic poles with a larger mass flow to the leeward pole of the star. In the case of a relatively large stellar magnetic field, the star's magnetic field is stretched in the direction of the matter flow outside of R_m (towards the windward side of the star). For weaker magnetic fields we observed oscillations of the closed magnetosphere frontward and backward. These are accompanied by strong oscillations of the mass accretion rate which varies by factors ~ 3. Old slowly rotating neutron stars with no radio emission may be visible in the X-ray band due to accretion of interstellar matter. In general, the star's velocity, magnetic moment, and angular velocity vectors may all be in different directions so that the accretion luminosity will be modulated at the star's rotation rate.

description: Geometry of Vavilov-Cherekov (VChR) radiation when an electron moves close to a dielectric target is in analogy to diffraction radiation (DR) geometry. In this case we may expect DR generation from the upstream face of the target besides that VChR. The joint observation of these booth types of radiation is very interesting from the pseudo-photon viewpoint, which is applicable for relativistic electrons. Unexpected results obtained in our experiment insist on reflection about nature both DR and VChR. The experiment was performed on the relativistic electron beam of the microtron of Tomsk Polytechnic University.

description: Bibliography: p. 211-234
description: Src-associated in mitosis 68 kDa (Sam68) is an RNA binding protein identified 10 years ago as a mitosis specific target for Src tyrosine kinase. It belongs to the signal transduction and activation of RNA metabolism (STAR) protein family. These proteins are thought to link signaling pathways with some aspect of RNA metabolism. Although the function of Sam68 is unknown it has been reported to play a role in several biological processes such as: viral replication, cell signaling, alternative pre-mRNA splicing, cell cycle regulation, and has been suggested to be a tumour suppressor and a transcriptional regulator. It has been demonstrated that the activity of Sam68 can be regulated by post-translational modifications such as tyrosine or serine/threonine phosphorylation. Tyrosine phosphorylation was shown to inhibit Sam68 binding to synthetic poly(U) RNA, and serine/threonine phosphorylation was shown to influence the ability of Sam68 to alter splice site selection. Since Sam68 is predominantly a nuclear protein there are several post-translational modifications common to nuclear proteins that have not yet been described for Sam68. For example, acetylation, sumoylation and ubquitination are three post-translational modifications described for numerous nuclear proteins. Here I report that Sam68 can be acetylated, and that acetylation positively regulates its binding to poly(U) RNA. As well, Sam68 is shown to be sumoylated. Conjugation with SUMO altered Sam68 subnuclear localization and its ability to act as
