description: We consider a hidden sector model of dark matter which is charged under a hidden U(1)_X gauge symmetry. Kinetic mixing of U(1)_X with the Standard Model hypercharge U(1)_Y is allowed to provide communication between the hidden sector and the Standard Model sector. We present various limits on the kinetic mixing parameter and the hidden gauge coupling constant coming from various low energy observables, electroweak precision tests, and the right thermal relic density of the dark matter. Saturating these constraints, we show that the spin-independent elastic cross section of the dark matter off nucleons is mostly below the current experimental limits, but within the future sensitivity. Finally, we analyze the prospect of observing the hidden gauge boson through its dimuon decay channel at hadron colliders.

description: Context. Omega Cen is the largest known globular cluster in the Milky Way. It is also quite a complex object with a large metallicity spread and multiple stellar populations. Despite a number of studies over the past several decades, the series of events that led to the formation of this cluster is still poorly understood. One of its peculiarities is the presence of a metal-rich population which does not show the phenomenon of light-element anti-correlations (C-N, Na-O, Mg-Al), a trait that is considered as characteristic of Galactic Globular Clusters, and is in fact present among more metal-poor Omega Cen stars, leading to speculations that such anomalous population was accreted by the cluster. In this paper, we aim at investigating the kinematics of Omega Cen populations to gain insight on the formation scenario of the cluster. Using the newly released Gaia FPR and DR3 catalogue, we conducted a detailed kinematical analysis of cluster members within Omega Cen. The cluster members were divided into four metallicity populations and their mean proper motion in radial and tangential components were compared with each other. We also performed Gaussian Mixture Model fitting on the metallicity distribution to estimate the number of populations within our sample and an independent analysis of the HST catalogue as confirmation. The mean proper motions (mu_r and mu_t) of the metallicity populations do not show any significant differences. It is also not dependent on the approach chosen to determine the number of metallicity populations. We do find clear signature of rotation in all of the populations (including the metal-rich) with similar velocities.

description: Theories unifying gravity with other interactions suggest spatial and temporal variation of fundamental "constants" in the Universe. A change in the fine structure constant, alpha, could be detected via shifts in the frequencies of atomic transitions in quasar absorption systems. Recent studies using 140 absorption systems from the Keck telescope and 153 from the Very Large Telescope, suggest that alpha varies spatially. That is, in one direction on the sky alpha seems to have been smaller at the time of absorption, while in the opposite direction it seems to have been larger. To continue this study we need accurate laboratory measurements of atomic transition frequencies. The aim of this paper is to provide a compilation of transitions of importance to the search for alpha variation. They are E1 transitions to the ground state in several different atoms and ions, with wavelengths ranging from around 900 - 6000 A, and require an accuracy of better than 10^{-4} A. We discuss isotope shift measurements that are needed in order to resolve systematic effects in the study. The coefficients of sensitivity to alpha-variation (q) are also presented.

description: The fundamental properties of brown dwarfs evolve with age. Models describing the evolution of luminosities and effective temperatures, among other physical parameters, can be empirically constrained using brown dwarfs of various masses in star clusters of well determined age and metallicity. We aim to carry out a spectroscopic and photometric characterization of low-mass brown dwarfs of the ~120 Myr old Pleiades open cluster. We obtained low-resolution near-infrared spectra of the J=17.4-18.8 mag candidate L-type brown dwarfs PLIZ 28 and 35, BRB 17, 21, 23, and 29, which are Pleiades members by photometry and proper motion. We also obtained spectra of the well-known J=15.4-16.1 mag late M-type cluster members PPl 1, Teide 1, and Calar 3. We find that the former six objects have early- to mid-L spectral types and confirm previously reported M-types for the other three objects. The spectra of the L0-type BRB 17 and PLIZ 28 present a triangular H-band continuum shape, indicating that this peculiar spectral feature persists until at least the age of the Pleiades. We add to our sample 36 reported M5-L0-type cluster members, collecting their I_c - and UKIDSS ZYJHK-band photometry. We confirm a possible interleaving of the Pleiades and field L-type sequences in the JHK absolute magnitude versus spectral type diagrams, and quantify marginally redder Pleiades J-K colours, by 0.12+-0.20 mag, possibly related to both reddening and youth. Using field dwarf bolometric correction - and effective temperature - spectral type relations, we obtain the Hertzsprung-Russell diagram of the Pleiades sample. Theoretical models reproduce well the spectral sequence at M5.5-9, but appear to overestimate the luminosity or underestimate the effective temperature at L0-5. For the Pleiades early- to mid L-type brown dwarfs, we estimate theoretical masses to be in the range 0.025-0.035 M_Sol.

A nossa premissa é a Bíblia, mais especificamente o relato do livro de Génesis cap. 6, sobre os Nefilins.  A menção de gigantes ocorre por várias nas Sagradas Escrituras, e como tal, muitas questões sobre estes gigantes surgem, como por exemplo: Se realmente existiram? O que os caracterizavam? E como desapareceram? Expomos também várias semelhanças que existem entre os gigantes descritos na Bíblia, e dos gigantes do povos nativos das américas. O livro de 1 Enoque, tem um papel central neste estudo para entendermos o que aconteceu antes do diluvio. As interpretações rabínicas aqui apresentadas servem de apoio para elucidar todos os desdobramentos acerca deste importante capítulo do livro de Génesis. - Teodorus R. Guerreiro - Academia.edu

description: The LASCO coronagraphs, in continuous operation since 1995, have observed the evolution of the solar corona and coronal mass ejections (CMEs) over a full solar cycle with high quality images and regular cadence. This is the first time that such a dataset becomes available and constitutes a unique resource for the study of CMEs. In this paper, we present a comprehensive investigation of the solar cycle dependence on the CME mass and energy over a full solar cycle (1996-2009) including the first in-depth discussion of the mass and energy analysis methods and their associated errors. Our analysis provides several results worthy of further studies. It demonstrates the possible existence of two event classes; 'normal' CMEs reaching constant mass for $>10$ R$_{\sun}$ and 'pseudo' CMEs which disappear in the C3 FOV. It shows that the mass and energy properties of CME reach constant levels, and therefore should be measured, only above $\sim 10 R_\sun$. The mass density ($g/R_\sun^2$) of CMEs varies relatively little ($

description: Multistate dark matter (DM) models with small mass splittings and couplings to light hidden sector bosons have been proposed as an explanation for the PAMELA/Fermi/H.E.S.S. high-energy lepton excesses. We investigate this proposal over a wide range of DM density profiles, in the framework of concrete models with doublet or triplet dark matter and a hidden SU(2) gauge sector that mixes with standard model hypercharge. The gauge coupling is bounded from below by the DM relic density, and the Sommerfeld enhancement factor is explicitly computable for given values of the DM and gauge boson masses M, mu and the (largest) dark matter mass splitting delta M_{12}. Sommerfeld enhancement is stronger at the galactic center than near the Sun because of the radial dependence of the DM velocity profile, which strengthens the inverse Compton (IC) gamma ray constraints relative to usual assumptions. We find that the PAMELA/Fermi/H.E.S.S. lepton excesses are marginally compatible with the model predictions, and with CMB and Fermi gamma ray constraints, for M ~ 800 GeV, mu ~ 200 MeV, and a dark matter profile with noncuspy Einasto parameters alpha > 0.20, r_s ~ 30 kpc. We also find that the annihilating DM must provide only a subdominant (< 0.4) component of the total DM mass density, since otherwise the boost factor due to Sommerfeld enhancement is too large.
description: 20 pages, 12 figures; v2: Corrected branching ratio for ground state DM annihilations into leptons, leading to boost factors that are larger than allowed. Added explicit results for doublet DM model. Some conclusions changed; main conclusion of tension between inverse Compton constraints and N-body simulations of halo profiles is unchanged

description: We investigate Meissner effect in normal metal/superconductor junctions where the interface is spin-active. We find that orbital magnetic susceptibility of the normal metal shows highly nontrivial behaviors. In particular, the magnetic susceptibility depends on the temperature in an oscillatory fashion, accompanied by its sign change. Correspondingly, magnetic field and current density can spatially oscillate in the normal metal. The possible spontaneous formation of the current pattern is also discussed. These results are attributed to the generation of odd-frequency pairing due to the spin-active interface.

Epigenetic regulation of blood-brain barrier transporters
Creators: name: You, Dahea
Publisher: name: No Publisher Supplied
Year: 2019

description: The blood-brain barrier (BBB) restricts the exchange of numerous endo- and xenobiotics between the circulation and the brain parenchyma. The primary cellular component of the BBB is the brain microvascular endothelium which possess multiple mechanisms of protection, one of which is the presence of the transporters. Multidrug resistance protein 1 (MDR1, ABCB1, P-glycoprotein) and breast cancer resistance protein (BCRP, ABCG2) are key efflux transporters located along the apical surface of BBB endothelial cells. Both transporters play significant roles in extruding chemicals from the brain endothelium back to the circulation. Prior studies in cancer cells have demonstrated that pharmacological inhibition of histone deacetylases (HDACs) can up-regulate the expression and function of MDR1 and BCRP transporters due to enhanced histone acetylation. The purpose of this dissertation was to determine the extent to which inhibition of HDAC enzymes regulates efflux transporters at the BBB. In immortalized human brain capillary endothelial (hCMEC/D3) cells, a human model of the BBB, both mRNA and protein expression of MDR1 and BCRP were up-regulated by multiple HDAC inhibitors including valproic acid (VPA), apicidin, and suberoylanilide hydroxamic acid (SAHA). Increased MDR1 expression corresponded with enhanced MDR1 function, as indicated by reduced intracellular accumulation of rhodamine 123, a fluorescent substrate of MDR1. Further investigation of the molecular mechanisms underlying transporter up-regulation in hCMEC/D3 cells revealed that SAHA increased the binding of acetylated histone H3K9/14 proteins within the MDR1 promoter region containing response elements for the aryl hydrocarbon receptor (AHR). Pharmacological manipulation was used to assess the role of AHR as a transcriptional activator of MDR1 following HDAC inhibition. Concurrent treatment with beta-naphthoflavone, an AHR activator, amplified SAHA-mediated induction of MDR1 expression while CH-223191, an AHR inhibitor, prevented the induction of MDR1 by SAHA. Moreover, binding of AHR was increased at the MDR1 promoter in SAHA-treated hCMEC/D3 cells. These data indicate that histone acetylation and AHR signaling cooperatively regulate MDR1 expression following pharmacological inhibition of HDACs. Finally, a 7-day in vivo study demonstrated that HDAC inhibitors can regulate Mdr1 and Bcrp transporter expression in the brains of mice in a region-specific manner. Collectively, the data presented in this dissertation identify a novel epigenetic mechanism that can regulate the MDR1 and BCRP transporters at the BBB and potentially affect levels of neuroactive compounds in the brain.
Evaluation of a ligand-directed labeling molecule targeting integrin alphaVbeta5
Creators: name: Slattery, Wyatt Thomas
Publisher: name: University of British Columbia
Year: 2018

description: Integrins are transmembrane receptors that mediate cellular adhesion to the extracellular matrix and initiate signaling cascades that may be relevant to synaptic elimination events occurring in neurodegenerative disease. To study the role of integrins in synaptic elimination, a novel ligand-directed labeling molecule has been created, comprised of the Pacific Blue™ (PB) fluorophore and the high-affinity integrin inhibitor, cilengitide. It was hypothesized that the function of integrin αVβ5 could be studied in live cells by using this probe to track subcellular integrin localization through fluorescence microscopy. This study evaluated the pharmacodynamic properties of the PB-probe, finding that its fluorescence excitation and emission properties are similar to PB and highly photostable over the time period of at least 2 h. Fluorescence enhancement and anisotropy experiments revealed that a derivative of the probe binds integrin αVβ5 with a dissociation constant of 0.11 ± 0.07 μM. Binding was competitively inhibited by cilengitide, suggesting that both molecules compete for the integrin binding domain with similar affinities. Application to BV-2 murine microglia in vitro confirmed that the PB-probe is a robust and rapidly applicable labeling method for the fluorescence detection of endogenous integrins. These experiments demonstrated that PB-probe labeling is specific, amenable to a variety of sample preparation methods, and compatible with simultaneous immunocytochemistry techniques. Separately, the PB-probe was found to inhibit integrin-mediated signaling cascades with equal efficacy as cilengitide. The results of this study confirm that the PB-probe retains both similar fluorescent properties as PB and the integrin-binding properties of cilengitide. These findings establish the PB-probe as an effective means of tracking endogenous integrin αVβ5 in live-cell systems, representing a critical first step in understanding the role of integrin signaling in synaptic elimination.

description: We investigate medium effects due to density-dependent magnetic moments of baryons on neutron stars under strong magnetic fields. If we allow the variation of anomalous magnetic moments (AMMs) of baryons in dense matter under strong magnetic fields, AMMs of nucleons are enhanced to be larger than those of hyperons. The enhancement naturally affects the chemical potentials of baryons to be large and leads to the increase of a proton fraction. Consequently, it causes the suppression of hyperons, resulting in the stiffness of the equation of state. Under the presumed strong magnetic fields, we evaluate relevant particles' population, the equation of state and the maximum masses of neutron stars by including density-dependent AMMs and compare them with those obtained from AMMs in free space.

description: We present the broadband X-ray properties of four of the most X-ray luminous (L_X >= 10^{45} erg/s in the 0.5-2 keV band) radio-quiet QSOs found in the ROSAT Bright Survey. This uniform sample class, which explores the extreme end of the QSO luminosity function, exhibits surprisingly homogenous X-ray spectral properties: a soft excess with an extremely smooth shape containing no obvious discrete features, a hard power law above 2 keV, and a weak narrow/barely resolved Fe K-alpha fluorescence line for the three high signal-to-noise ratio (S/N) spectra. The soft excess can be well fitted with only a soft power law. No signatures of warm or cold intrinsic absorbers are found. The Fe K-alpha centroids and the line widths indicate emission from neutral Fe (E=6.4 keV) originating from cold material from distances of only a few light days or further out. The well-constrained equivalent widths (EW) of the neutral Fe lines are higher than expected from the X-ray Baldwin effect which has been only poorly constrained at very high luminosities. Taking into account our individual EW measurements, we show that the X-ray Baldwin effect flattens above L_X ~ 10^{44} erg/s (2-10 keV band) where an almost constant of ~100 eV is found. We confirm the assumption of having very similar X-ray AGN properties when interpreting stacked X-ray spectra. Our stacked spectrum serves as a superb reference for the interpretation of low S/N spectra of radio-quiet QSOs with similar luminosities at higher redshifts routinely detected by XMM-Newton and Chandra surveys.

description: Long chain omega-3 fatty acids found in marine sources are among the most important human nutrients. However, their susceptibility to oxidation and unpleasant fishy flavour could lead to their rejection by consumers.This thesis investigates the effect of milkfat as a stable fat to protect omega-3 fatty acids and to mask their undesirable flavour. Moreover, this thesis proposes a promising approach to fortify dairy products with combination of milkfat and omega-3 fatty acids.

description: В статье рассматриваются тенденции санаторно-курортной отрасли России в целом, а также в разрезе ключевых регионов, на долю которых приходится 73% доходов всей отрасли. Кроме того, были выявлены санаторно-курортные организации, показавшие наилучшие темпы прироста по выручке, выявлены их конкурентные преимущества. По итогам анализа было установлено, что в последние годы санаторно-курортная отрасль России находилась в сложном положении. Она стагнировала после прохождения пика в 2016 г., вследствие падения доходов населения и снижения спроса со стороны корпораций. Восстановительный рост 2018-2019 года не позволил вернутся на пиковые значения 2016 г. В ближайшие годы состояние санаторно-курортной отрасли будет оставаться неустойчивым в связи с экономическими последствиями борьбы с новой коронавирусной инфекцией COVID-19. Автором было установлено, что основные «истории успеха» связаны с развитием санаториев в «среднем» и «выше среднего» сегментах за счет развития инфраструктуры, сервиса и продвижения услуг. Начался процесс формирования сетей. По мере падения доходов усилится ценовая конкуренция при сохранении запросов клиентов к качеству услуг. В среднесрочной перспективе продолжится уход с рынка «неэффективных игроков». После закрытия спроса на качественный отдых в высоком ценовом сегменте (4-5 звезд по гостиничной классификации) возможно развитие качественного предложения в сегменте 3* и ниже, появление «дискаунтеров» с адекватным уровнем сервиса.

description: Elemental abundances in the solar corona differ from those in the photosphere, with low first ionization potential (FIP) elements being enhanced, a phenomenon known as the FIP effect. This enhancement is attributed to ponderomotive forces linked to magnetohydrodynamic (MHD) waves, particularly incompressible transverse waves. Our study investigates the relationship between coronal abundance fractionation and chromospheric transverse MHD waves by examining the spatial correlation between FIP fractionation and these waves and by analyzing their properties to test the ponderomotive force model. We used H alpha data from the Fast Imaging Solar Spectrograph at the Goode Solar Telescope to detect chromospheric transverse MHD waves and \ion{Si}{X} (low FIP) and \ion{S}{X} (high FIP) spectra from Hinode EUV Imaging Spectrometer to determine relative abundances in an active region. Extrapolated linear force free magnetic fields from Solar Dynamics Observatory/Helioseismic and Magnetic Imager magnetograms further linked the observed chromospheric waves with coronal composition. Approximately 400 wave packets were identified and characterized by their period, velocity amplitude, propagation speed, and direction. These incompressible or weakly compressible waves were mainly observed near loop footpoints in the sunspot penumbra and superpenumbral fibrils. Regions of high FIP fractionation coincided with closed magnetic fields where these waves were present, and low-frequency, downward-propagating waves comprised about 43/% of the total. Our results demonstrate a strong correlation between coronal abundance fractionation and chromospheric transverse MHD waves, supporting the view that the FIP effect is driven by the ponderomotive force from these waves.

description: We study isotropic and anisotropic (Bianchi I) cosmologies in Palatini $f(R)$ and $f(R,R_{μν}R^{μν})$ theories of gravity and consider the existence of non-singular bouncing solutions in the early universe. We find that all $f(R)$ models with isotropic bouncing solutions develop shear singularities in the anisotropic case. On the contrary, the simple quadratic model $R+a R^2/R_P+R_{μν}R^{μν}/R_P$ exhibits regular bouncing solutions in both isotropic and anisotropic cases for a wide range of equations of state, including dust (for $a<0$) and radiation (for arbitrary $a$). It thus represents a purely gravitational solution to the big bang singularity and anisotropy problems of general relativity without the need for exotic ($w>1$) sources of matter/energy.

Multiscale computational methods to study the formation and flow of amphiphile-based colloidal particles

Publisher: name: No Publisher Supplied

description: Colloids are defined as large insoluble particles uniformly suspended in a medium including gas, liquid, and solid.  Different from atoms and small molecules, one interesting property of colloids is its collective behavior: a property that nano-scaled colloids exhibit as a result of colloidal self interaction and interaction with surrounding medium. It is believed that this property plays an important role in colloidal self-organize, sedimentation, phase segregation, as well as crystallization. Hollow nanostructures, such as vesicles, due to their stability, low toxicity, intracellular communication ability, and compatibility with human tissue, has gained considerable scientific interests as a type of potential drug delivery vehicle. Due to current lack of knowledge of stability of vesicles in microfluidic devices or in blood flow, first part of this study (Chapter 2) presents how nanoparticles behave by changing architecture and relative concentrations of the molecular species of the nanoparticles under various flow conditions using a simulation technique called DPD.  The second part of this study (Chapter3 and 4) focus on implantation of a new multi-scale simulation technique in investigation of membrane systems. The hybrid lattice Boltzmann-molecular dynamics method (MDLBM) is able to capture molecular details of solutes and hydrodynamic interactions of fluid simultaneously, while saving computational time compared with traditional explicit solvent molecular dynamic methods. In Chapter 3, dynamics and mechanical properties of vesicles and bi-layers are tested and shown to be close to previous studies. In Chapter 4, current coupling scheme is modified and applied to study self-assembly process of lipids. Modified MDLBM algorithm is able to capture dynamical process of colloids, where the hydration shells are spontaneously replaced by interactions with other molecular species in solution, for example in processes encompassing aggregation or interfacial adsorption.
Unruptured intracranial aneurysms and the Trial on Endovascular Aneurysm Management (TEAM): The principles behind the protocol.

Publisher: name: Zenodo

description: With the widespread availability of non-invasive imaging of the brain in an aging population, we are increasingly confronted with the problem of the incidental discovery of unruptured aneurysms. The management of these patients remains controversial. Endovascular treatment can prevent rupture, but involves immediate risks. Furthermore, successful treatment does not eliminate all risk of rupture. The safety and efficacy of endovascular treatment of unruptured aneurysms remain undetermined. Hence the balance of the risks and benefits is uncertain. A randomized trial is needed to assess the potential benefits of endovascular management of unruptured aneurysms.
The Trial: TEAM (Trial on Endovascular Aneurysm Management) is a randomized trial comparing endovascular treatment versus conservative management of unruptured aneurysms. TEAM aims to recruit 2002 patients in 60 centers throughout the world over a 3-year period and to follow all patients for 10 years. The primary outcome is to verify if the clinical outcome (morbidity/mortality (modified Rankin scale > 2) related to the aneurysm or its treatment) can be improved from 8% to 4%. The study is funded by the Canadian Institutes of Health Research.

Transition state theory: a generalization to nonequilibrium systems with power-law distributions

description: Transition state theory (TST) is generalized for the nonequilibrium system with power-law distributions. The stochastic dynamics that gives rise to the power-law distributions for the reaction coordinate and momentum is modeled by the Langevin equations and corresponding Fokker-Planck equations. It is assumed that the system far away from equilibrium has not to relax to a thermal equilibrium state with Boltzmann-Gibbs distribution, but asymptotically approaches to a nonequilibrium stationary-state with power-law distributions. Thus, we obtain a generalization of TST rates to nonequilibrium systems with power-law distributions. Furthermore, we derive the generalized TST rate constants for one-dimension and n-dimension Hamiltonian systems away from equilibrium, and receive a generalized Arrhenius rate for the system with power-law distributions.

Structural insights into inhibitory mechanisms of cathepsin K

Publisher: name: University of British Columbia

description: Cathepsin K (CatK) is a lysosomal cysteine protease highly expressed in osteoclasts and is responsible for the degradation of bone. Implication of CatK in various musculoskeletal disorders including osteoporosis highlights CatK as an important target for drug development. This thesis aims to identify and characterize different classes of CatK inhibitors, which target the active site and collagenolytically relevant ectosteric sites using X-ray crystallography combined with mutational and kinetic studies. In chapter 2, odanacatib, a specific CatK inhibitor recently abandoned in clinical trials due to adverse side effects, was investigated for its selectivity for mouse CatK over the human counterpart. Structural, mutagenic, and kinetic studies identified two structural features in the mouse enzyme which determines odanacatib’s selectivity. Replacement of these features from the human counterpart was able to restore inhibitory activity in the mouse enzyme. In chapters 3 and 4, composite docking and high throughput fluorescence polarization (FP) assay methods were developed to identify novel ectosteric inhibitors of CatK by targeting the protein oligomerization site required for collagen degradation. Screening of the NCI Database (280,000 compounds) using three distinct molecular modeling methods identified nine active compounds. The best compound had an IC50 value around 300 nM in cell-based resorption assays. Over 5,000 compounds were also screened using a developed FP assay and nine collagenase inhibitors were identified. Three of these compounds were active in subsequent cell-based assays. In chapter 5, NSC-13345, the structure of a putative allosteric inhibitor of CatK described in literature was determined in complex with the enzyme using X-ray crystallography. Previous characterization was performed using an inactive variant and the allosteric site affected by the presence of an extra loop. Structural determination with the fully processed enzyme identified three binding sites. One site located above the active site may explain its substrate selective inhibition. In addition, the crystal structure of T-06, a potent collagenase inhibitor of CatK, in complex with CatK was determined and provided insight into its ectosteric inhibition. These findings suggest that NSC-13345 and T-06 function as a substrate selective ectosteric inhibitors for CatK.
