description: The compressible Navier-Stokes-Poisson (NSP) system is considered in $R^3$ in the present paper and the influences of the electric field of the internal electrostatic potential force governed by the self-consistent Poisson equation on the qualitative behaviors of solutions is analyzed. It is observed that the rotating effect of electric field affects the dispersion of fluids and reduces the time decay rate of solutions. Indeed, we show that the density of the NSP system converges to its equilibrium state at the same $L^2$-rate $(1+t)^{-\frac34}$ or $L^\infty$-rate $(1+t)^{-3/2}$ respectively as the compressible Navier-Stokes system, but the momentum of the NSP system decays at the $L^2$-rate $(1+t)^{-\frac14}$ or $L^\infty$-rate $(1+t)^{-1}$ respectively, which is slower than the $L^2$-rate $(1+t)^{-\frac34}$ or $L^\infty$-rate $(1+t)^{-3/2}$ for the compressible Navier-Stokes system. These convergence rates are also shown to be optimal for the compressible NSP system.

Osoonikihi paksuses Eesti kohal ei ole täheldatud olulisi muutusi alates 1979. aastast. UV-kiirgust mõõdetakse Tõraveres alates 1997. aastast. Integraalse päikesekiirguse mõõtmis tulemuste abil on rekonstrueeritud erüteemse UV-kiirguse doosid tagasi  ulatuvalt 1953. aastani. Suvisel poolaastal koguneb 89% aastasest erüteemsest ja 80% integraalsest kiirgusest. Erüteemse kiirguse doosid varieeruvad aastati vähem kui integraalse kiirguse doosid. Talvel esineb 50ndast suurematel laiuskraadidel periood, kus D-vitamiini sünteesiks ei ole piisavalt UV-kiirgust. Tõraveres kestab see normaal tingimustel 6. novembrist kuni 19. veebruarini.

description: Sisehaigused on üks vanemaid meditsiinierialasid. Tehnoloogia kiire areng, uute ravi- ja diagnoosimis -meetodite juurutamine on tinginud arstide kitsama spetsialiseerumise vajaduse ka sisehaiguste vallas. Samas on inimene ühtne tervik ja haigused ei pruugi kahjustada vaid ühte elundit, seetõttu peab arst oskama haiget inimest ja haigusi hinnata ning käsitleda laiemalt kui oma kitsa spetsialiteedi vaatenurgast. Eesti oludes ei ole ei inim- ega materiaalseid ressursse arvestades võimalik avada igas haiglas kõiki kitsamaid sisehaiguste erialasid. Väljapääsuks ja edasise arengu võtmeks on tihedam koostöö eri asutuste vahel ja sisearstide koolitamine, et nad paremini orienteeruksid ka sisehaiguste kitsama eriala sagedamini ette tulevates probleemides.

The Simultaneous Formation of Massive Stars and Stellar Clusters

description: We show that massive stars and stellar clusters are formed simultaneously, the global evolution of the forming cluster is what allows the central stars to become massive. We predict that massive star forming clumps, such as those observed in Motte et al. 2007, contract and grow in mass leading to the formation of massive stars. This occurs as mass is continually channeled from large radii onto the central proto-stars, which can become massive through accretion. Using SPH simulations of massive star forming clumps in a Giant Molecular Cloud, we show that clumps are initially diffuse and filamentary, and become more concentrated as they collapse. Simulated interferometry observations of our data provide an explanation as to why young massive star forming regions show more substructure than older ones. The most massive stars in our model are found within the most bound cluster. Most of the mass accreted by the massive stars was originally distributed throughout the clump at low densities, and was later funneled to the star due to global in-fall. Even with radiative feedback no massive pre-stellar cores are formed. The original cores are of intermediate mass and gain their additional mass in the proto-stellar stage. We also find that cores which form low mass stars exist within the volume from which the high mass stars accrete, but are largely unaffected by this process.

description: We have investigated the magnetic and dielectric properties of Ca$_2$CoSi$_2$O$_7$ crystal. The dielectricity and magnetism of Ca$_2$CoSi$_2$O$_7$ are strongly coupled below a canted antiferromagnetic transition temperature ($T_{\rm N}$): Magnetic fields induce electric polarization below $T_{\rm N}$. Interestingly, the magnetic-field-induced electric polarization is detected even without poling electric fields. Below $T_{\rm N}$, a canted antiferromagnetic-paramagnetic transition is induced by magnetic fields. The large magnetocapacitance is observed around $T_{\rm N}$. The origin of the large magnetocapacitance is due to the magnetic-field-induced the canted antiferromagnetic-paramagnetic transition.

description: We use Hubble Space Telescope Fine Guidance Sensor astrometry and high-cadence radial velocities for HD136118 from the HET with archival data from Lick to determine the complete set of orbital parameters for HD136118b. We find an orbital inclination for the candidate exoplanet of i_{b} = 163.1 +- 3.0 deg. This establishes the actual mass of the object, M_{b} = 42^{+11}_{-18} MJup, in contrast to the minimum mass determined from the radial velocity data only, M_{b}sin{i} ~ 12 MJup. Therefore, the low-mass companion to HD 136118 is now identified as a likely brown dwarf residing in the "brown dwarf desert".

description: With the start-up of the LHC, we can hope to find evidences for new physics beyond the Standard Model, and particle candidates for dark matter. Determining the parameters of the full underlying theory will be a long process requiring the combination of LHC and ILC data, flavor physics constraints, and cosmological observations. However, the Very Early Universe properties, from which the relic particles originate, are poorly known, and the relic density calculation can be easily falsified by hidden processes. We consider supersymmetry and show that determining the underlying particle physics parameters will help understanding the Very Early Universe properties.

description: The LDA+DMFT (local density approximation combined with dynamical mean-field theory) computation scheme has been used to study spectral and magnetic properties of FeSi and Fe$_{1-x}$Co$_{x}$Si. Having compared different models we conclude that a correlated band insulator scenario in contrast to Kondo insulator model agrees with FeSi band structure as well as experimental data. Coulomb correlation effects lead to band narrowing of the states near the Fermi level with mass renormalization parameter $m^*\approx 2$ in agreement with the results of angle-resolved photoemission spectroscopy (ARPES). Temperature dependence of spectral functions and magnetic susceptibility calculated in DMFT reproduces transition from nonmagnetic semiconductor to metal with local magnetic moments observed experimentally. Cobalt doping leads to ferromagnetism that has itinerant nature and can be successfully described by LDA+DMFT method.

Comparative effects of three experimental warm-up conditions upon accuracy
Creators: name: Benedict, Graham Evans
Publisher: name: University of British Columbia
Year: 2011

description: Two problems were examined with respect to the influence of various preliminary warm-up procedures upon accuracy as measured by the basketball free throw; first, the hypothesis that scores following a related warm-up will be higher than scores without a warm-up or scores following an unrelated warm-up; second, that there will be no significant difference between performance following an unrelated warm-up and performance without preliminary warm-up exercise. Ten highly skilled basketball players were selected to serve as subjects in the experiment. Each player was tested nine times, three times after each of the conditions of (a) no warm-up, (b) related warm-up, and (c) unrelated warm-up. The order of the experimental conditions was rotated to balance out possible learning effects and to minimize the error that might be caused by systematic sequence of testing. Results indicated that the related warm-up was significantly more effective in producing better shooting scores than either the unrelated warm-up or shooting without a preliminary warming-up. Secondly, there was no significant difference between scores obtained without a warm-up and scores made following an unrelated warm-up. It was concluded that where a related warm-up is at all possible this method is recommended over the unrelated warm-up and no warm-up to facilitate an increase in basketball free throw accuracy.

description: Let $S$ be a set of $n^2$ symbols. Let $A$ be an $n\times n$ square grid with each cell labeled by a distinct symbol in $S$. Let $B$ be another $n\times n$ square grid, also with each cell labeled by a distinct symbol in $S$. Then each symbol in $S$ labels two cells, one in $A$ and one in $B$. Define the \emph{combined distance} between two symbols in $S$ as the distance between the two cells in $A$ plus the distance between the two cells in $B$ that are labeled by the two symbols. Belén Palop asked the following question at the open problems session of CCCG 2009: How to arrange the symbols in the two grids such that the minimum combined distance between any two symbols is maximized? In this paper, we give a partial answer to Belén Palop's question. Define $c_p(n) = \max_{A,B}\min_{s,t \in S} \{\dist_p(A,s,t) + \dist_p(B,s,t) \}$, where $A$ and $B$ range over all pairs of $n\times n$ square grids labeled by the same set $S$ of $n^2$ distinct symbols, and where $\dist_p(A,s,t)$ and $\dist_p(B,s,t)$ are the $L_p$ distances between the cells in $A$ and in $B$, respectively, that are labeled by the two symbols $s$ and $t$. We present asymptotically optimal bounds $c_p(n) = Θ(\sqrt{n})$ for all $p=1,2,...,\infty$. The bounds also hold for generalizations to $d$-dimensional grids for any constant $d \ge 2$. Our proof yields a simple linear-time constant-factor approximation algorithm for maximizing the minimum combined distance between any two symbols in two grids.

description: The initial value problem is considered in the present paper for bipolar quantum hydrodynamic model for semiconductors (QHD) in $\mathbb{R}^3$. We prove that the unique strong solution exists globally in time and tends to the asymptotical state with an algebraic rate as $t\to+\infty$. And, we show that the global solution of linearized bipolar QHD system decays in time at an algebraic decay rate from both above and below. This means in general, we can not get exponential time-decay rate for bipolar QHD system, which is different from the case of unipolar QHD model (where global solutions tend to the equilibrium state at an exponential time-decay rate) and is mainly caused by the nonlinear coupling and cancelation between two carriers. Moreover, it is also shown that the nonlinear dispersion does not affect the long time asymptotic behavior, which by product gives rise to the algebraic time-decay rate of the solution of the bipolar hydrodynamical model in the semiclassical limit.

Algebraic Bethe ansatz for U(1) Invariant Integrable Models: Compact and non-Compact Applications

Publisher: name: arXiv
Year: 2009
Subjects: subject: Mathematical Physics (math-ph)

description: We apply the algebraic Bethe ansatz developed in our previous paper \cite{CM} to three different families of U(1) integrable vertex models with arbitrary $N$ bond states. These statistical mechanics systems are based on the higher spin representations of the quantum group $U_q[SU(2)]$ for both generic and non-generic values of $q$ as well as on the non-compact discrete representation of the $SL(2,{\cal R})$ algebra. We present for all these models the explicit expressions for both the on-shell and the off-shell properties associated to the respective transfer matrices eigenvalue problems. The amplitudes governing the vectors not parallel to the Bethe states are shown to factorize in terms of elementary building blocks functions. The results for the non-compact $SL(2,{\cal R})$ model are argued to be derived from those obtained for the compact systems by taking suitable $N \to \infty$ limits. This permits us to study the properties of the non-compact $SL(2,{\cal R})$ model starting from systems with finite degrees of freedom.

description: The semi-classical Wigner-Kirkwood $\hbar$ expansion method is used to calculate shell corrections for spherical and deformed nuclei. The expansion is carried out up to fourth order in $\hbar$. A systematic study of Wigner-Kirkwood averaged energies is presented as a function of the deformation degrees of freedom. The shell corrections, along with the pairing energies obtained by using the Lipkin-Nogami scheme, are used in the microscopic-macroscopic approach to calculate binding energies. The macroscopic part is obtained from a liquid drop formula with six adjustable parameters. Considering a set of 367 spherical nuclei, the liquid drop parameters are adjusted to reproduce the experimental binding energies, which yields a {\it rms} deviation of 630 keV. It is shown that the proposed approach is indeed promising for the prediction of nuclear masses.

Karpaalkanali sündroomi ebaõnnestunud konservatiivsele ravile järgneb sageli kirurgiline ravi. Meie uuringu eesmärk oli uurida retrospektiivselt KKSi operatiivse ravi tulemuslikkuse sõltuvust preoperatiivsest injektsioonravist 5 aastat pärast operatsiooni ning teha kindlaks, kas preoperatiivne injektsioonravi halvendab karpaalkanali sündroomi põdevate inimeste operatsioonijärgseid kaugtulemusi.  Patsiendid ja metoodika. Uuringusse kaasati 2005. aasta jooksul Tartu Ülikooli Kliinikumi neurokirurgia osakonnas opereeritud 164 patsienti (174 kätt). Patsiente intervjueeriti telefoni teel 5–6 aastat pärast operatsiooni. Kõigi patsientide käest küsiti tehtud süstete arvu ning hinnangut kaebuste taandumisele 100 punkti skaalal.

description: We used the multiplex capabilities of the AAOmega spectrograph at the Anglo-Australian Telescope to create a half-square-degree map of the neutral and low-ionized ISM in front of the nearby (~5 kpc), most massive Galactic globular cluster, omega Centauri. Its redshifted, metal-poor and hot horizontal branch stars probe the medium-strong Ca II K and Na I D2 line absorption, and weak absorption in the lambda5780 and lambda5797 Diffuse Interstellar Bands (DIBs), on scales around a parsec. The kinematical and thermodynamical picture emerging from these data is that we predominantly probe the warm neutral medium and weakly-ionized medium of the Galactic Disc-Halo interface, ~0.3-1 kpc above the mid-plane. A comparison with Spitzer Space Telescope 24-micron and DIRBE/IRAS maps of the warm and cold dust emission confirms that both Na I and Ca II trace the overall column density of the warm neutral and weakly-ionized medium. Clear signatures are seen of the depletion of calcium atoms from the gas phase into dust grains. Curiously, the coarse DIRBE/IRAS map is a more reliable representation of the relative reddening between sightlines than the Na I and Ca II absorption-line measurements, most likely because the latter are sensitive to fluctuations in the local ionization conditions. The behaviour of the DIBs is consistent with the lambda5780 band being stronger than the lambda5797 band in regions where the ultraviolet radiation level is relatively high, as in the Disc-Halo interface. This region corresponds to a sigma-type cloud. In all, our maps and simple analytical model calculations show in unprecedented detail that small-scale density and/or ionization structures exist in the extra-planar gas of a spiral galaxy.

Long-term evolution of the spin of Mercury I. Effect of the obliquity and core-mantle friction

description: The present obliquity of Mercury is very low (less than 0.1 degree), which led previous studies to always adopt a nearly zero obliquity during the planet's past evolution. However, the initial orientation of Mercury's rotation axis is unknown and probably much different than today. As a consequence, we believe that the obliquity could have been significant when the rotation rate of the planet first encountered spin-orbit resonances. In order to compute the capture probabilities in resonance for any evolutionary scenario, we present in full detail the dynamical equations governing the long term evolution of the spin, including the obliquity contribution. The secular spin evolution of Mercury results from tidal interactions with the Sun, but also from viscous friction at the core-mantle boundary. Here, this effect is also regarded with particular attention. Previous studies show that a liquid core enhances drastically the chances of capture in spin-orbit resonances. We confirm these results for null obliquity, but we find that the capture probability generally decreases as the obliquity increases. We finally show that, when core-mantle friction is combined with obliquity evolution, the spin can evolve into some unexpected configurations as the synchronous or the 1/2 spin-orbit resonance.

Effects of an endurance exercise program on cardiovascular variables of a group of middle-aged men
Creators: name: Olafson, Gordon Albert Alexander
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study was to evaluate the effects of an endurance exercise program on a group of middle-aged men. Ten subjects were tested before and after seventeen weeks of endurance training at The University of British Columbia using five tests, three of which were tests of cardiovascular condition. The tests used are as follows: 1. Schneider Test Variables are: lying pulse rate, standing pulse rate, post-exercise pulse rate, time for pulse rate to return to standing value, difference between pulse rate lying to standing, and standing to post-exercise difference, lying systolic blood pressure, standing systolic blood pressure, the difference between lying and standing systolic blood pressure and Schneider index score. 2. Progressive Pulse Ratio Variables are: recovery pulse counts for rates of 12, 18, 24, 30 and 36 steps per minute, average ratio and average angle. 3. Pulse Pressure Wave. (Brachial Sphygmograph) Variables are: A. Sitting area under the curve, systolic amplitude, dicrotic notch amplitude, fatigue ratio, diastolic amplitude, rest-to-work ratio, obliquity angle, systolic time, diastolic time, pulse rate, systolic blood pressure, diastolic blood pressure and pulse pressure. B. Standing area under the curve, pulse rate, systolic amplitude, difference between sitting and standing systolic amplitude. C. Post-Exercise systolic amplitude 4. Body Fat Measurements Variables are: cheek fold, abdominal fold, hip fold, front thigh fold, gluteal fold, rear thigh fold, sum of all and average. 5. Body Weight Significant changes at the .05 level of confidence occurred in ten variables of forty-four used in this study. A significant reduction in body fat at the .05 level of confidence occurred in the abdominal fold, front thigh fold, gluteal fold, sum of all and average of all, though a reduction in body weight was not significant at the .05 level of confidence. Sitting pulse rate, sitting systolic blood pressure, standing airea under the curve and standing pulse rate of the Pulse Pressure Wave were significant at the .05 level of confidence. One variable of the Schneider Test - time for the pulse to return to standing value - was significant at the .05 level of confidence. No significant changes occurred in the Progressive Pulse Ratio Test variables. Only three correlation co-efficients were of sufficient size to be considered significantly different from zero. These were the co-efficients of correlation between attendance and average pulse ratio, front thigh fat fold and rear thigh fat fold. Although only five of thirty-five cardiovascular variables showed statistically significant improvements, the members of the group stated that their tolerance to the stress of the endurance exercise program had improved.

description: We perform variational Monte-Carlo calculations to show that bosons in a rotating optical lattice will form analogs of fractional quantum Hall states when the tunneling is sufficiently weak compared to the interactions and the deviation of density from an integer is commensurate with the effective magnetic field. We compare the energies of superfluid and correlated states to one-another and to the energies found in full configuration-interaction calculations on small systems. We look at overlaps between our variational states and the exact ground-state, characterizing the ways in which fractional quantum Hall effect correlations manifest themselves near the Mott insulating state. We explore the experimental signatures of these states.

description: In November 2020, a Baseline study was conducted among 342 participants, followed by an awareness campaign. Then an Endline study was carried out with 337 other participants in January 2021, to assess communities’ knowledge, attitudes, and practices (KAP) related to rabies in the same study areas. The same questionnaires were used to assess communities KAP. A significant improvement in participants' KAP related to rabies was observed. The good knowledge average score increased from 36% to 61%, positive attitudes improved from 39% to 55%, and good practices increased from 7% to 81%. The participants mean KAP score increases from 27% at Baseline to 66% at Endline. Multivariable logistic regressions performed after both phases revealed that participants who heard or saw information about rabies during an awareness campaign had higher KAP levels compared to others. This study demonstrated the awareness campaign importance, and the need to continue and intensify efforts to raise rural communities’ awareness, by using mass communication methods such as radio broadcasts, video spots and flyers in local language to reach more people.

Ensuite, une étude de fin (Endline) a été réalisée auprès de 337 autres participants en janvier 2021 pour évaluer les connaissances, attitudes et pratiques (CAP) des communautés liées à la rage dans les mêmes zones d'étude. Les mêmes questionnaires ont été utilisés pour évaluer les CAP des communautés. Une amélioration significative des CAP des participants liées à la rage a été observée. Le score moyen des bonnes connaissances est passé de 36 % à 61 %, les attitudes positives ont progressé de 39 % à 55 % et les bonnes pratiques ont augmenté de 7 % à 81 %. Le score moyen des CAP des participants est passé de 27 % au début à 66 % à la fin. Des régressions logistiques multivariées effectuées après les deux phases ont révélé que les participants ayant entendu ou vu des informations sur la rage lors d'une campagne de sensibilisation avaient des niveaux de CAP plus élevés que les autres. Cette étude a démontré l'importance de la campagne de sensibilisation et la nécessité de poursuivre et d'intensifier les efforts pour sensibiliser les communautés rurales, en utilisant des méthodes de communication de masse telles que les diffusions radio, les spots vidéo et les dépliants dans la langue locale pour toucher un plus grand nombre de personnes.

description: General relativity postulates the Minkowski space-time to be the standard flat geometry against which we compare all curved space-times and the gravitational ground state where particles, quantum fields and their vacuum states are primarily conceived. On the other hand, experimental evidences show that there exists a non-zero cosmological constant, which implies in a deSitter space-time, not compatible with the assumed Minkowski structure. Such inconsistency is shown to be a consequence of the lack of a application independent curvature standard in Riemann's geometry, leading eventually to the cosmological constant problem in general relativity. We show how the curvature standard in Riemann's geometry can be fixed by Nash's theorem on locally embedded Riemannian geometries, which imply in the existence of extra dimensions. The resulting gravitational theory is more general than general relativity, similar to brane-world gravity, but where the propagation of the gravitational field along the extra dimensions is a mathematical necessity, rather than being a a postulate. After a brief introduction to Nash's theorem, we show that the vacuum energy density must remain confined to four-dimensional space-times, but the cosmological constant resulting from the contracted Bianchi identity is a gravitational contribution which propagates in the extra dimensions. Therefore, the comparison between the vacuum energy and the cosmological constant in general relativity ceases to be. Instead, the geometrical fix provided by Nash's theorem suggests that the vacuum energy density contributes to the perturbations of the gravitational field.

description: Abstract

Whatever text is created, the image of the author - its creator - determines all the elements of the structure (theme, idea, composition, selection and organization of linguistic means, etc.). The problem of studying the author's linguistic personality has been studied by many domestic and foreign linguists, philologists, and literary scholars. Of course, the image of the author in a literary text differs from his textual embodiment in other areas of communication, but its general integrating principle remains unchanged. The means, methods and forms of its implementation are changing. The choice of different types of narrators, which is far from random, is indicative. The author and his point of view on the subject of the image manifests itself in different forms. The article considers the main provisions of some of the presented theories.

description: Spatial Independent Component Analysis (ICA) is an increasingly used data-driven method to analyze functional Magnetic Resonance Imaging (fMRI) data. To date, it has been used to extract meaningful patterns without prior information. However, ICA is not robust to mild data variation and remains a parameter-sensitive algorithm. The validity of the extracted patterns is hard to establish, as well as the significance of differences between patterns extracted from different groups of subjects. We start from a generative model of the fMRI group data to introduce a probabilistic ICA pattern-extraction algorithm, called CanICA (Canonical ICA). Thanks to an explicit noise model and canonical correlation analysis, our method is auto-calibrated and identifies the group-reproducible data subspace before performing ICA. We compare our method to state-of-the-art multi-subject fMRI ICA methods and show that the features extracted are more reproducible.
