description: We report on the results of multi-wavelength follow-up observations with Gemini, VLA, and ATCA, to search for a host galaxy and any persistent radio emission associated with FRB 180309. This FRB is among the most luminous FRB detections to date, with a luminosity of $> 8.7\times 10^{32}$ erg Hz$^{-1}$ at the dispersion-based redshift upper limit of 0.32. We used the high-significance detection of FRB 180309 with the Parkes Telescope and a beam model of the Parkes Multibeam Receiver to improve the localization of the FRB to a region spanning approximately $\sim2'\times2'$. We aimed to seek bright galaxies within this region to determine the strongest candidates as the originator of this highly luminous FRB. We identified optical sources within the localization region above our r-band magnitude limit of 24.27, fourteen of which have photometric redshifts whose fitted mean is consistent with the redshift upper limit ($z < 0.32$) of our FRB. Two of these galaxies are coincident with marginally detected "persistent" radio sources of flux density 24.3$μ$Jy beam$^{-1}$ and 22.1$μ$Jy beam$^{-1}$ respectively. Our redshift-dependent limit on the luminosity of any associated persistent radio source is comparable to the luminosity limits for other localized FRBs. We analyze several properties of the candidate hosts we identified, including chance association probability, redshift, and presence of radio emission, however it remains possible that any of these galaxies could be the host of this FRB. Follow-up spectroscopy on these objects to explore their H$α$ emission and ionization contents, as well as to obtain more precisely measured redshifts, may be able to isolate a single host for this luminous FRB.

Beyond chemically defined – Characterization of chemically defined cell culture medium for the cultivation of CHO cells
Creators: name: Krattenmacher, Florian
Publisher: name: Universität Bielefeld
Year: 2020
Subjects: subject: 570

description: Chemically defined media (CDM) for cell culture are routinely used in industrial processes for recombinant protein production from mammalian expression systems as for example Chinese hamster ovary (CHO) cells. As CDM are nowadays considered as the industry standard the focus has shifted from implementation and improvement of performance to additionally their chemical behavior and the impact on process robustness. Since CDM are highly concentrated aqueous mixtures of versatile chemical compounds one particular problem in this context is the high risk for chemical reactions and instability.
 Therefore, a major focus of this thesis is the generation of understanding for chemical interactions of CDM compounds and especially the establishment of analytical technologies for the purpose of media characterization. Thus, a mixed mode liquid chromatography tandem mass spectrometry (LC-QqQ-MS) method that is able to simultaneously quantify the majority of media compounds has been developed and validated. This powerful method has been applied to characterize the chemical behavior of feed media under process relevant conditions as preparation and storage. Further on line and off line analytics have been applied to gain insight into CDM chemistry.
 The application of probes measuring standard parameters have shown the dynamic behavior of chemical key parameters during CDM powder hydration. A Particle probe, such as the focused beam reflectance measurement (FBRM), has been shown to be useful for dissolution behavior investigations of different media recipes or powder compositions. However, it is rather difficult to establish the technology for batch to batch comparison or the monitoring of deviations from the standard preparation conditions. Media preparations with simplified media powders revealed that the compounds ascorbic acid and phosphates cause an apparent drop in dissolved oxygen concentration upon iron compound addition. The combination of the experiments with the newly developed LC QqQ MS method confirmed the comparability of chemical behavior in different media matrixes of most of the CDM compounds but highlighted some differences. Furthermore, measurements with the LC-QqQ-MS showed that the effect of preparation temperature and relevant storage conditions on media stability were negligible. In contrast, measurement of samples over storage time identified unstable compounds. A closer look at the media after storage showed that some formulations formed precipitate during storage and the collection of the solid material on filter membranes revealed their different appearance. Investigations of the material with specialized analytics proved that their identity was heterogeneous. One precipitate that was drawing attention on itself was of silver color and could be shown to consist of Sulphur.

description: This is the second in a series of papers whose aim is to generate ``adiabatic'' gravitational waveforms from the inspiral of stellar-mass compact objects into massive black holes. In earlier work, we presented an accurate (2+1)D finite-difference time-domain code to solve the Teukolsky equation, which evolves curvature perturbations near rotating (Kerr) black holes. The key new ingredient there was a simple but accurate model of the singular source term based on a discrete representation of the Dirac-delta function and its derivatives. Our earlier work was intended as a proof of concept, using simple circular, equatorial geodesic orbits as a testbed. Such a source is effectively static, in that the smaller body remains at the same coordinate radius and orbital inclination over an orbit. (It of course moves through axial angle, but we separate that degree of freedom from the problem. Our numerical grid has only radial, polar, and time coordinates.) We now extend the time-domain code so that it can accommodate dynamic sources that move on a variety of physically interesting world lines. We validate the code with extensive comparison to frequency-domain waveforms for cases in which the source moves along generic (inclined and eccentric) bound geodesic orbits. We also demonstrate the ability of the time-domain code to accommodate sources moving on interesting non-geodesic worldlines. We do this by computing the waveform produced by a test mass following a ``kludged'' inspiral trajectory, made of bound geodesic segments driven toward merger by an approximate radiation loss formula.

description: Bloch states of electrons in honeycomb two-dimensional crystals with multi-valley band structure and broken inversion symmetry have orbital magnetic moments of a topological nature. In crystals with two degenerate valleys, a perpendicular magnetic field lifts the valley degeneracy via a Zeeman effect due to these magnetic moments, leading to magnetoelectric effects which can be leveraged for creating valleytronic devices. In this work, we demonstrate that trilayer graphene with Bernal stacking, (ABA TLG) hosts topological magnetic moments with a large and widely tunable valley g-factor, reaching a value 1050 at the extreme of the studied parametric range. The reported experiment consists in sublattice-resolved scanning tunneling spectroscopy under perpendicular electric and magnetic fields that control the TLG bands. The tunneling spectra agree very well with the results of theoretical modeling that includes the full details of the TLG tight-binding model and accounts for a quantum-dot-like potential profile formed electrostatically under the scanning tunneling microscope tip.

description: Interaction between a Bloch wall in a ferrite-garnet film and a vortex in a superconductor is analyzed in the London approximation. Equilibrium distribution of vortices formed around the Bloch wall is calculated. The results agree quantitatively with magneto-optical experiment where an in-plane magnetized ferrite-garnet film placed on top of NbSe2 superconductor allows observation of individual vortices. In particular, our model can reproduce a counter-intuitive attraction observed between vortices and a Bloch wall having the opposite polarity. It is explained by magnetic charges appearing due to discontinuity of the in-plane magnetization across the wall.

description: We study the finite temperature transition in QCD with three flavors of equal masses using the R and RHMC algorithm on lattices with temporal extent N_τ=4 and 6. For the transition temperature in the continuum limit we find r_0 T_c=0.429(8) for the light pseudo-scalar mass corresponding to the end point of the 1st order transition region. When comparing the results obtained with the R and RHMC algorithms for p4fat3 action we see no significant step-size errors down to a lightest pseudo-scalar mass of m_{ps} r_0=0.4.

Interaction of viruses with human joint material

description: An in vitro cell and organ culture system for the study of human arthrotropic viruses was established to determine the permissiveness of joint cells and tissue to five strains of rubella virus (RV), adenovirus type 2 (Ad) and human parvovirus (B19). A semi-continuous line of fetal chondrocytes (FC) and primary synovial membrane/cartilage (SMC) cells were used to investigate virus/joint cell interactions. In addition, the SMC cells were used to determine the ability of a virus to establish a persistent infection in cells of joint origin. Intact joint tissue containing both synovial membrane and cartilage was also infected to determine the ability of the viruses to replicate in non-dividing cells and also their invasive capability in the presence of an extracellular matrix. Results showed that all RV strains and Ad were able to replicate in FC, SMC cells and intact joint tissue. The only exception to this was that replication of RV strain Cendehill was not detected in joint tissue. In contrast, there was no indication, by either DNA-DNA hybridization or immunoperoxidase staining, that B19 was able to replicate in SMC cells. Most importantly, the behaviour of the rubella strains in this model was found to correlate with the clinical data concerning the incidence of complications associated with rubella infection or vaccination. This suggests that arthritogenicity is related to the ability of a particular virus to infect and persist in joint tissue and establishes the in vitro model as a useful system to evaluate the arthrotropicity of future rubella vaccines.

description: Nonlinear surface-plasmon polaritons~(NSPPs) in nanophotonic waveguides excite with dissimilar temporal properties due to input field modifications and material characteristics, but they possess similar nonlinear spectral evolution. In this work, we uncover the origin of this similarity and establish that the spectral dynamics is an inherent property of the system that depends on the synthetic dimension and is beyond waveguide geometrical dimensionality. To this aim, we design an ultra-low loss nonlinear plasmonic waveguide, to establish the invariance of the surface plasmonic frequency combs~(FCs) and phase singularities for plasmonic peregrine waves and Akhmediev breather. By finely tuning the nonlinear coefficient of the interaction interface, we uncover the conservation conditions through this plasmonic system and employ the mean-value evolution of the quantum NSPP field commensurate with the Schrödinger equation to evaluate spectral dynamics of the plasmonic FCs~(PFCs). Through providing suppressed interface losses and modified nonlinearity as dual requirements for conservative conditions, we propose exciting PFCs as equally spaced invariant quantities of this plasmonic scheme and prove that the spectral dynamics of the NSPPs within the interaction interface yields the formation of plasmonic analog of the synthetic photonic lattice, which we termed \textit{synthetic plasmonic lattice}~(SPL).

description: Taust. Vaktsiiniga välditavate haiguste üldine vähenemine on tinginud rahvastikus leviva kahtluse suurenemise lapse vaktsineerimise vajaduse suhtes. Tõenduspõhised andmed Eesti lapsevanemate arusaamade kohta seoses vaktsineerimisega puuduvad. Eesmärk. Selgitada Eesti lapsevanemate vaktsineerimiskäitumist ja uskumusi seoses plaanilise vaktsineerimisega ning seda mõjutavaid tegureid. Metoodika. Kasutati veebipõhist ankeetküsitlust (8. novembrist 7. detsembrini 2017). Valimi moodustas 1557 lapsevanemat, kelle noorim laps oli noorem kui 5aastane. Ankeedi tulemuste põhjal jaotati uuritavad vaktsineerijateks (72,3%), kahtlejateks (11,9%) ja mittevaktsineerijateks (15,8%). Nende vaktsinatsioonikäitumise mõjurite selgitamiseks kasutati logistilist regressioonanalüüsi. Uskumusi hinnati 5astmelisel Likerti skaalal. Tulemused. Oma last vaktsineerida on suurem šanss 25–34aastastel, võrreldes vanematega kui 35 aastat, ja väiksema sissetulekuga lapsevanematel. Kahtlejad on pigem üle 35aastased kui 25–34aastased. Mittevaktsineerijatel on rohkem kui 1 laps, samuti on mitttevaktsineerijad suuremapalgalised. Arvamused vaktsineerimise, selle olulisuse ja efektiivsuse kohta erinesid kõikides rühmades. Enim usuti, et vaktsineerimine kaitseb haiguste eest (78,7%; vaktsineerijad 96,4%; kahtlejad 65,1%; mittevaktsineerijad 8,1%), ja vaktsiiniga välditavaid haigusi peeti raskeks (74,3%; vastavalt 90,9%; 62,4%; 7,3%). Kahtlejad ja mittevaktsineerijad usaldasid vähem kui vaktsineerijad nii tervishoidu kui ka sellega seotud institutsioone, näiteks peab arstide soovitusi usaldusväärseks 71,7% (vastavalt 89,3% vaktsineerijatest, 46,8% kahtlejatest ja 9,8% mittevaktsineerijatest) ja Terviseameti soovitusi 67,6% (vastavalt 86,7% vaktsineerijatest, 39,8% kahtlejatest ja 1,6% mittevaktsineerijatest) vanematest. Järeldused. Uuring näitab, et lapsevanemad kahtlevad vaktsiinide ohutuses ja vajalikkuses. Et vältida vaktsineerimisest keeldumise trendi suurenemist, tuleks suurendada usaldust vaktsineerimise suhtes.

description: Kindlasti on paljud arstid kokku puutunud olukorraga, kui ühel ja samal patsiendil on samal ajal leitud mitu erinevat pahaloomulist kasvajat või on haigestunud ta nendesse elu jooksul korduvalt. Taoliste haigestumiste korral on tegemist vastavalt kas sünkroonsete või metakroonsete mitmikkasvajatega. Kirjanduses defineeritakse mitmikkasvajana olukorda, kus ühel ja samal isikul on olnud rohkem kui üks sünkroonne või metakroonne pahaloomuline kasvaja. Mitmikkasvajate sageduseks on erinevad uurimisrühmad esitanud 2–17%. Mitmikkasvajate korral peab arvestama võimalusega, et patsiendil on tegemist mõne päriliku kasvajasündroomiga, mis enamasti tähendab, et haigust põhjustav geenimuutus on esinenud ka ühel või mõlemal tema vanematest. Haige ja tema perekonna paremaks käsitlemiseks võib sellisel juhul olla abi geneetilistest uuringutest. TÜ Kliinikumi kliinilise geneetika keskuses on olemas kõik tänapäevased võimalused nn mendeleeruvate haiguste, k.a pärilike kasvajasündroomide diagnoosimiseks. Kuna geneetiku konsultatsioonile on mitmikkasvajaga patsiente suunatud suhteliselt vähe, on artikli eesmärk tutvustada mõningaid mitmikkasvajaid põhjustavaid pärilikke sündroome ning suurendada arstkonna teadlikkust geneetiliste uuringute võimalustest.

Restoration of randomly blurred images with measurement error in the point spread function
Creators: name: Lam, Edward W. H.
Publisher: name: University of British Columbia
Year: 2010

description: The restoration of images degraded by a stochastic, time varying point spread func-tion(PSF) is addressed. The object to be restored is assumed to remain fixed during the observation time. A sequence of observations of the unknown object is assumed available. The true value of the random PSF is not known. However, for each observation a "noisy" measurement of the random PSF at the time of observation is assumed available. Practical applications in which the PSF is time varying include situations in which the images are obtained through a nonhomogeneous medium such as water or the earth's atmosphere. Under such conditions, it is not possible to determine the PSF in advance, so attempts must be made to extract it from the degraded images themselves. A measurement of the PSF may be obtained by either isolating a naturally occurring point object in the scene, such as a reference star in optical astronomy, or by artificially installing an impulse light source in the scene. The noise in the measurements of point spread functions obtained in such a manner are particularly troublesome in cases when the light signals emitted by the point object are not very strong. In this thesis, we formulate a model for this restoration problem with PSF measurement error. A maximum likelihood filter and a Wiener filter are then developed for this model. Restorations are performed on simulated degraded images. Comparisons are made with standard filters of the classical restoration model(ignoring the PSF error), and also with results based on the averaged degraded image and averaged PSF's. Experimental results confirm that the filters we developed perform better than those based on averaging and than those ignoring the PSF measurement error.

description: Local density fluctuations near the QCD critical point has been suggested to exhibit a power-law behavior which can be probed by an intermittency analysis on scaled factorial moment (SFM) in relativistic heavy-ion collisions. The collision energy and centrality dependence of the second-order SFMs are systematically investigated in Au $+$ Au collisions at $\sqrt{s_{NN}}$ = 7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV within the UrQMD model. We estimate the noncritical background in the measurement of intermittency and propose a cumulative variable method to effectively remove the background contributions. We further study the effect of particle detection efficiency by implementing the RHIC (STAR) experimental tracking efficiencies in the UrQMD events. A cell-by-cell method is proposed for experimental application of efficiency corrections on SFM. This work can provide a guidance of background subtraction and efficiency correction for the experimental measurement of intermittency in the search of the QCD critical point in heavy-ion collisions.

description: The characteristics of ionized and HI gas in the peculiar star/cluster complex in NGC 6946, obtained with the 6-m telescope (BTA) SAO RAS, the Gemini North telescope, and the Westerbork Synthesis Radio Telescope (WSRT), are presented. The complex is unusual as hosting a super star cluster, the most massive known in an apparently non-interacting giant galaxy. It contains a number of smaller clusters and is bordered by a sharp C-shaped rim. We found that the complex is additionally unusual in having peculiar gas kinematics. The velocity field of the ionized gas reveals a deep oval minimum, ~300 pc in size, centered 7" east of the supercluster. The Vr of the ionized gas in the dip center is 100 km/s lower than in its surroundings, and emission lines within the dip appear to be shock excited. This dip is near the center of an HI hole and a semi-ring of HII regions. The HI (and less certainly, HII) velocity fields reveal expansion, with the velocity reaching ~30 km/s at a distance about 300 pc from the center of expansion, which is near the deep minimum position. The super star cluster is at the western rim of the minimum. The sharp western rim of the whole complex is plausibly a manifestation of a regular dust arc along the complex edge. Different hypotheses about the complex and the Vr depression origins are discussed, including a HVC/dark mini-halo impact, a BCD galaxy merging, and a gas outflow due to release of energy from the supercluster stars.

Käsimüügiravimid eneseraviks – kas mõistame võimalikke riske?

description: Käsimüügiravimid sisaldavad samu toimeaineid nagu retsepti alusel väljastatavad ravimid. Enamikul juhtudel on käsimüügiravimite annus ja pakendite suurus väiksemad kui sama toimeainega retseptiravimitel, kuid patsient võib osta neid mitu pakki ja seega võib lühiaegseks kasutamiseks mõeldud ravimi tarvitamine pikeneda ja kokku kasutatud annused suureneda. Võib-olla olulisem risk tekib, kui kasutataval käsimüügiravimil on negatiivne koostoime samal ajal kasutamisel olevate retseptiravimitega. Näiteks võib mittesteroidsetel põletikuvastastel valuvaigistitel olla neerutoksiline koostoime reniin-angiotensiinsüsteemi blokaatoridega. Paratsetamool suurtes annustes on hepatotoksiline ja võimendab antikoagulantide toimet. Atsetüülsalitsüülhappe ja varfariini samaaegne kasutamine on vastunäidustatud. Ravimiamet hindab käsimüügiravimite ohutust ja nende ravimite õige kasutamine on üsna ohutu.

description: Acne fulminans’i (AF) puhul on tegemist harva esineva ja kulult raskeima akne vormiga. Haigusele on omane ülakehale, kaelale ja näole puhangutena tekkiv papuloos-nodulaarne haavanduv lööve. Haigestumisega võivad kaasneda süsteemsed kaebused nagu palavik, kaalulangus ning muskuloskeletaalne valu. Kuigi AFi tekkepõhjused ei ole paljuski teada, on eksperdid soovitanud klassifitseerida AFi kas de novo või akne ravis kasutatava isotretinoiini tõttu tekkinuks (1). AFi ravi on keerukas, tihti pikaajaline ning põhineb vähesel kliinilisel kogemusel. Patsiendid võivad haiguse raskes faasis vajada haiglaravi, paranemise järel jäävad nahale armid.

$B_{(s)},D_{(s)} \to π, K, η, ρ, K^*, ω, ϕ$ Transition Form Factors and Decay Rates with Extraction of the CKM parameters $|V_{ub}|$, $|V_{cs}|$, $|V_{cd}|$

description: A systematic calculation for the transition form factors of heavy to light mesons ($B,B_s,D,D_s \to π, K, η, ρ, K^*, ω, ϕ$) is carried out by using light-cone sum rules in the framework of heavy quark effective field theory. The heavy quark symmetry at the leading order of $1/m_Q$ expansion enables us to reduce the independent wave functions and establish interesting relations among form factors. Some relations hold for the whole region of momentum transfer. The meson distribution amplitudes up to twist-4 including the contributions from higher conformal spin partial waves and light meson mass corrections are considered. The CKM matrix elements $|V_{ub}|$, $|V_{cs}|$ and $|V_{cd}|$ are extracted from some relatively well-measured decay channels. A detailed prediction for the branching ratios of heavy to light meson decays is then presented. The resulting predictions for the semileptonic and radiative decay rates of heavy to light mesons ($B,B_s,D,D_s \to π, K, η, ρ, K^*, ω, ϕ$) are found to be compatible with the current experimental data and can be tested by more precise experiments at B-factory, LHCb, BEPCII and CLEOc.

"Worst-Case" Micro-Lensing in the Identification and Modeling of Lensed Quasars

description: Although micro-lensing of macro-lensed quasars and supernovae provides unique opportunities for several kinds of investigations, it can add unwanted and sometimes substantial noise. While micro-lensing flux anomalies may be safely ignored for some observations, they severely limit others. "Worst-case" estimates can inform the decision whether or not to undertake an extensive examination of micro-lensing scenarios. Here, we report "worst-case" micro-lensing uncertainties for point sources lensed by singular isothermal potentials, parameterized by a convergence equal to the shear and by the stellar fraction. The results can be straightforwardly applied to non-isothermal potentials utilizing the mass sheet degeneracy. We use micro-lensing maps to compute fluctuations in image micro-magnifications and estimate the stellar fraction at which the fluctuations are greatest for a given convergence. We find that the worst-case fluctuations happen at a stellar fraction $κ_\star=\frac{1}{|μ_{macro}|}$. For macro-minima, fluctuations in both magnification and demagnification appear to be bounded ($1.5>Δm>-1.3$, where $Δm$ is magnitude relative to the average macro-magnification). Magnifications for macro-saddles are bounded as well ($Δm > -1.7$). In contrast, demagnifications for macro-saddles appear to have unbounded fluctuations as $1/μ_{macro}\rightarrow0$ and $κ_\star\rightarrow0$.

Strong fields with E>(\sqrtλM_{KK})^2 free quark pairs, causing the confined vacuum and matter state to decay. We generalize Schwinger's QED persistence function to dense hQCD. At high temperature and density, Ohm's law is derived generalizing a recent result by Karch and O'Bannon to the chiral case.

description: We revisit Higgs inflation in the framework of a minimal extension of the Standard Model gauge symmetry by a $U(1)_{B-L}$ factor. Various aspects are taken into account with particular focus on the role of the supersymmetry breaking (SUSY) scale and the cosmological constraints associated with the gravitino. The scalar potential of the model is considered in the context of no-scale supergravity consisting of the F-part constructed from the Kähler function, the D-terms and soft SUSY contributions. We investigate several limiting cases and by varying the SUSY scale from a few TeV up to intermediate energies, for a spectral index around $n_s\sim 0.9655$ and reheating temperature $T_r\le 10^{9}$ GeV we find that the value of the tensor-to-scalar ratio ranges from $r\approx 10^{-3}$ to $10^{-2}$. Furthermore, it is shown that for certain regions of the parameter space the gravitino can live sufficiently long and as such is a potential candidate for a dark matter component. In general, the inflationary scenario is naturally implemented and it is consistent with non-thermal leptogenesis whereas the dominant decay channel of the inflaton yields right-handed neutrinos. Other aspects of cosmology and particle physics phenomenology are briefly discussed. Finally, we investigate the case where the inflaton is initially relaxed in a false minimum and estimate its probability to decay to the true vacuum.
