Core Structure of Intracluster Gas: Effects of Radiative Cooling on Core Sizes

description: We investigate the core structure of radiatively cooling intracluster gas, using a hydrodynamics code. We calculate evolution of model clusters of the initial core radii 160--300 kpc until the initial central cooling time, and analyze the resultant clusters using the double beta-model as done by observational studies. It is found that the core-size distribution thus obtained shows two peaks \sim 30--100 kpc and \sim 100--300 kpc and marginally can reproduce the observed distribution which exhibits two distinct peaks around \sim 50 kpc and \sim 200 kpc. This result may suggest radiative-cooling origin for small cores, while cooling is yet insignificant in the clusters of large cores. It should be noted that the small core peak is reproduced by clusters that are still keeping quasi-hydrostatic balance before the initial central cooling time has elapsed.

description: We analyze the morphological evolution of open clusters and provide shape parameters for 265 open clusters. The results show that the overall shape of sample clusters becomes more elliptical as they grow older, while their core remains circular or slightly trend to circularize. There is a negative correlation of the ellipticities with the number of members of the sample clusters. A significant negative correlation between the overall ellipticities and masses is also detected for the sample clusters with log(age/year) $\geq$ 8, suggesting that the overall shapes of the clusters are possibly influenced by the number of members and masses, in addition to the external forces and the surrounding environment. For most young sample clusters, the radial stratification degree of the short axis direction is greater than that of the long, implying that the radial stratification degree in the two directions within the young sample cluster may be unevenly affected by an internal evolutionary process. Older sample clusters exhibit lower stratification in the tangential direction, which possibly means those clusters may continue to survive for a long time at a low level of stratification. Our analysis shows that the overall shape of the sample clusters may be more susceptible to the influence of Galactic tides toward the Galactic center than the shear forces embedded in Galactic differential rotation. By analyzing the distribution of the ages and number of members of star clusters, we suggest that NGC 6791 may originate from superclusters.

description: We investigate the external reverse shock (RS) region of relativistic jets as the origin of X-ray afterglows of jetted tidal disruption events (TDEs) that exhibit luminous jets accompanied by fast-declining nonthermal X-ray emissions. We model the dynamics of jet propagating within an external density medium, accounting for continuous energy injection driven by accretion activities. We compute the time-dependent synchrotron and inverse Compton emissions from the RS region. Our analysis demonstrates that the RS scenario can potentially explain the X-ray light curves and spectra of four jetted TDEs, namely, AT 2022cmc, Swift J1644, Swift J2058, and Swift J1112. Notably, the rapid steepening of the late-stage X-ray light curves can be attributed jointly to the jet break and cessation of the central engine as the accretion rate drops below the Eddington limit. Using parameters obtained from X-ray data fitting, we also discuss the prospects for γ-ray and neutrino detection.

description: We perform a model-independent phenomenological analysis of experimental data on proton form factors ratio. We find that only one of the two photon exchange amplitudes, which we call $δG_M$, is responsible for the discrepancy between Rosenbluth and polarization methods. The linearity of Rosenbluth plots implies that $δG_M$ is approximately linear function of $ε$. The slope of $δG_M$ is extracted from experimental data and is shown to be consistent with theoretical calculations.

description: The macroscopic dynamics of a droplet impacting a solid is crucially determined by the intricate air dynamics occurring at the vanishingly small length scale between droplet and substrate prior to direct contact. Here we investigate the inverse problem, namely the role of air for the impact of a horizontal flat disk onto a liquid surface, and find an equally significant effect. Using an in-house experimental technique, we measure the free surface deflections just before impact, with a precision of a few micrometers. Whereas stagnation pressure pushes down the surface in the center, we observe a lift-up under the edge of the disk, which sets in at a later stage, and which we show to be consistent with a Kelvin-Helmholtz instability of the water-air interface.

description: We consider many-body states of bosonic spinor atoms which, at the mean-field level, can be characterized by a single-particle wave function. Such states include BEC phases and insulating Mott states with one atom per site. We describe and apply a classification scheme that makes explicit spin symmetries of such states and enables one to naturally analyze their collective modes and topological excitations. Quite generally, the method allows classification of a spin F system as a polyhedron with 2F vertices. After discussing the general formalism we apply it to the many-body states of bosons with hyperfine spins two and three. For spin-two atoms we find the ferromagnetic state, a continuum of nematic states, and a state having the symmetry of the point group of the regular tetrahedron. For spin-three atoms we obtain similar ferromagnetic and nematic phases as well as states having symmetries of various types of polyhedra with six vertices: the hexagon, the pyramid with pentagonal base, the prism, and the octahedron.

In particular we present approximate formulas for optimizing diversified portfolios and exact results for optimal investment in unknown games where the only available information is past outcomes.

description: Behavior of hysteretic trajectories for cyclical input is investigated as a function of the internal structure of a system modeled by the classical random network of binary spins. Different regimes of hysteretic behavior are discovered for different network connectivity and topology. Surprisingly, hysteretic trajectories which do not converge at all are observed. They are shown to be associated with the presence of specific topological elements in the network structure, particularly with the fully interconnected spin groups of size equal or greater than 4.

description: We perform correct and reasonable cosmological constraints on the newly proposed 4D Gauss-Bonnet gravity. Using the joint constraint from cosmic microwave background, baryon acoustic oscillations, Type Ia supernovae, cosmic chronometers and redshift space distortions, we obtain, so far, the strongest constraint $\tildeα=(1.2\pm5.2)\times 10^{-17}$, namely $α=(2.69\pm11.67)\times10^{48}$ eV$^{-2}$, among various observational limitations from different information channels, which is tighter than previous bound from the speed of gravitational wave by at least one order of magnitude. We find that our bound is well supported by the observations of temperature and lensing potential power spectra of cosmic microwave background from the Planck-2018 final release. Very interestingly, the large $H_0$ tension between the local measurement from the Hubble Space Telescope and global derivation from the Planck-2018 final data under the assumption of $Λ$CDM can be greatly resolved from $4.4σ$ to $1.94σ$ level in the 4D Gauss-Bonnet gravity. In theory, we find that this model can partly relieve the coincidence problem and the rescaling Gauss-Bonnet term, which needs the help of the cosmological constant to explain current cosmic acceleration, is unable to serve as dark energy alone.

description: Observations of protoplanetary disks around very low-mass stars and brown dwarfs remain challenging and little is known about their properties. The disk around CIDA1 ($\sim$0.1-0.2$M_\odot$) is one of the very few known disks that host a large cavity (20au radius in size) around a very low-mass star. We present new ALMA observations at Band7 (0.9mm) and Band4 (2.1mm) of CIDA1 with a resolution of $\sim 0.05''\times 0.034''$. These new ALMA observations reveal a very bright and unresolved inner disk, a shallow spectral index of the dust emission ($\sim2$), and a complex morphology of a ring located at 20au. We also present X-Shooter (VLT) observations that confirm the high accretion rate of CIDA1 of $\dot{M}_{\rm acc}$=1.4 $\times~10^{-8}M_\odot$/yr. This high value of $\dot{M}_{\rm acc}$, the observed inner disk, and the large cavity of 20au exclude models of photo-evaporation to explain the observed cavity. When comparing these observations with models that combine planet-disk interaction, dust evolution, and radiative transfer, we exclude planets more massive than 0.5$M_{\rm{Jup}}$ as the potential origin of the large cavity because with these it is difficult to maintain a long-lived and bright inner disk. Even in this planet mass regime, an additional physical process may be needed to stop the particles from migrating inwards and to maintain a bright inner disk on timescales of millions of years. Such mechanisms include a trap formed by a very close-in extra planet or the inner edge of a dead zone. The low spectral index of the disk around CIDA1 is difficult to explain and challenges our current dust evolution models, in particular processes like fragmentation, growth, and diffusion of particles inside pressure bumps.

description: We consider Randall-Sundrum scenarios based on SU(2)_L x SU(2)_R and a discrete parity exchanging L with R. The custodial and parity symmetries can be used to make the tree level contribution to the T parameter and the anomalous couplings of the bottom quark to the Z very small. We show that the resulting quantum numbers typically induce a negative T parameter at one loop that, together with the positive value of the S parameter, restrict considerably these models. There are nevertheless regions of parameter space that successfully reproduce the fit to electroweak precision observables with light Kaluza-Klein excitations accessible at colliders. We consider models of gauge-Higgs unification that implement the custodial and parity symmetries and find that the EW data singles out a very well defined region in parameter space. In this region one typically finds light gauge boson Kaluza-Klein excitations as well as light SU(2)_L singlet, and sometimes also doublet, fermionic states, that mix with the top quark, and may yield interesting signatures at future colliders.

At the upper pressure range, we observe a leakage rate smaller than our readout accuracy of $30\,$mbar per day.

title: Therapist Perspective of Therapeutic Alliance and Treatment Outcome in Systemic Psychotherapy
Creators: name: Patterson, Benjamin

Year: 2025
Subjects: classificationCode: 5.9
subject: FOS: Other social sciences

description: One of the most robust findings in psychotherapy outcome research has been the relationship of a strong therapeutic alliance with improvement in treatment. Most research, however, has measured therapeutic alliance from the client’s point of view, disregarding the therapist’s perspective of this phenomenon. In this naturalistic study of adults in systemic individual, couple, or family psychotherapy (N = 627), both client- and therapist-ratings of alliance were assessed for their associations with treatment outcomes. Multilevel modeling was employed to analyze data from the Marriage and Family Therapy Practice Research Network (MFT-PRN). Client-ratings of the therapeutic alliance and general functioning/relationship satisfaction at the start of treatment were both found to predict outcomes at the end of treatment. However, no association was found for the therapist’s rating of alliance, nor was the therapist’s rating found to moderate the relationship between client-ratings and therapy outcomes. Findings potentially highlight the asymmetric nature of the therapeutic relationship, with the client’s perspective of the alliance more salient for treatment outcomes, as well as the need for routine outcome monitoring to regularly assess therapeutic alliance strength.

description: We study the multifractality (MF) of critical wave functions at boundaries and corners at the metal-insulator transition (MIT) for noninteracting electrons in the two-dimensional (2D) spin-orbit (symplectic) universality class. We find that the MF exponents near a boundary are different from those in the bulk. The exponents at a corner are found to be directly related to those at a straight boundary through a relation arising from conformal invariance. This provides direct numerical evidence for conformal invariance at the 2D spin-orbit MIT. The presence of boundaries modifies the MF of the whole sample even in the thermodynamic limit.

On the undetected error probability of BCH codes
Creators: name: Chong, William
Publisher: name: University of British Columbia
Year: 2008

description: The undetected error probability, Pu(ε), for a variety of Bose-Chaudhuri-Hocquenghem (BCH) codes, used solely for error detection on a binary symmetric channel (BSC) with cross-over probability, is studied. The undetected error probability can be evaluated if the weight distribution of the code or its dual is available. Unfortunately, no general expression for the weight distribution of BCH codes which correct more than 3 errors is known. A few BCH codes for which it is computationally feasible to determine the weight clisiribution are studied. A proper code is one for which Pu(ε) increases monotonically with for 0 ≤ε≤0.5 Algorithms for determining the properness of linear block codes based on Fourier’s and Sturm’s Theorems for finding the number of real roots of a polynomial in a given interval are investigated. They are useful in cases where the weight distribution is known. Kasami et al have studied linear programming methods for obtaining upper and lower bounds on the weight distributions of 4- and 5-error-correcting BCH codes. Here, two methods which can be used to improve these bounds are presented. The first method uses the minimum distance of a dual BCH code. The second method requires, in addition, the number of codewords at the minimum distance. Comparisons between the improved bounds and the Kasami bounds are given for several BCH codes.

Open charm production in $\sqrt{s_{NN}}$=200 GeV Au+Au collisions
Creators: name: Zhang, Yifei

Year: 2006
Subjects: subject: Nuclear Experiment (nucl-ex)

description: We report on the measurement of D meson production from the analysis of their hadronic ($D^0\to Kπ$) and semileptonic ($D\to μ+X$, $D\to e+X$) decays in $\sqrt{s_{NN}}$=200 GeV Au+Au collisions. The transverse momentum ($p_T$) spectra and the nuclear modification factors for $D^0$ and for electron/muon from charm semileptonic decays will be presented. The differential cross section $dσ/dy$ is found to be consistent with the number of binary scaling. The blast-wave fit suggests that the charm hadron freeze out earlier than other light flavor hadrons.

description: The first detailed comparison between ab initio calculations of finite fermionic superfluid systems, performed recently by Chang and Bertsch [Phys. Rev. A 76, 021603(R), (2007)] and by von Stecher, Greene and Blume [e-print arXiv:00705:0671v1], and the extension of the density functional theory Superfluid Local Density Approximation (SLDA) is presented. It is shown that SLDA reproduces the total energies, number density distributions in inhomogeneous systems along with the energy of the normal state in homogeneous systems. Unlike the Kohn-Sham LDA, in SLDA the effective fermion mass differs from the bare fermion mass and the spectrum of elementary excitations is also reproduced.

description: Government Primary School teachers need special attention in rural areas. The current research was therefore planned with the goal of finding the views of GPS teachers on the challenges they face in rural areas, understanding the resources available to them, recognizing social problems in their school area and attempting to solve problems. A questionnaire was developed to achieve these objectives and information was collected through personal visits to randomly selected 26 rural schools consisting of 71 teachers. MS Excel was used for arrangement, tabulation and evaluating the collected information. The findings indicate that teachers in government primary schools (located in rural areas) face many challenges. Nonetheless, these issues have been addressed to some degree in recent years. The government needs to pay attention to primary schools in rural areas. The government of Khyber Pakhtunkhwa has taken a promising initiative to recruit Union Council primary school teachers and to appoint local primary school teachers to reduce these challenges. Adequate accommodation may however, be provided for outside teaching staff, or the local authority can take effective measures to reduce teacher absenteeism by improving the quality of transport facilities in rural areas. So they will take more interest in their attendance at school. The school building should be in good condition, and sufficient rooms, seats, electricity and a small library should be available for the students. Teaching staff should be provided to overcome the issue of overcrowded classrooms and teaching burden, especially in multi-grade teaching and two teacher schools. Courses should be revised and generated in simple and clear language according to student levels. To support teachers in primary school, several training sessions are conducted, i.e. Induction Software, Continuous Professional Development, etc. Teachers should seriously take such trainings to improve their teaching skills. Parents who live in rural areas or have no education background should be encouraged to send their children to school through different media to help increase the literacy rate in the rural areas of Kohat. Parents should collaborate with educators to produce better outcomes. Through the shared partnership of teachers, parents, farmers, and political elements with teachers' education can therefore be strengthened in rural areas.

description: The noncompact homogeneous sl(3) invariant spin chains are considered. We show that the transfer matrix with generic auxiliary space is factorized into the product of three sl(3) invariant commuting operators. These operators satisfy the finite difference equations in the spectral parameters which follow from the structure of the reducible sl(3) modules.

description: We propose the enhancement of $Λ_c$ yield in heavy ion collisions at RHIC and LHC as a novel signal for the existence of diquarks in the strongly coupled quark-gluon plasma produced in these collisions as well as in the $Λ_c$. Assuming that stable bound diquarks can exist in the quark-gluon plasma, we argue that the yield of $Λ_c$ would be increased by two-body collisions between $ud$ diquarks and $c$ quarks, in addition to normal three-body collisions among $u$, $d$ and $c$ quarks. A quantitative study of this effect based on the coalescence model shows that including the contribution of diquarks to $Λ_c$ production indeed leads to a substantial enhancement of the $Λ_c/D$ ratio in heavy ion collisions.

description: We study kink-antikink collisions in a model which interpolates smoothly between the completely integrable sine-Gordon theory, the $ϕ^4$ model, and a $ϕ^6$-like model with three degenerate vacua. We find a rich variety of behaviours, including integrability breaking, resonance windows with increasingly irregular patterns, and new types of windows near the $ϕ^6$-like regime. False vacua, extra kink modes and kink fragmentation play important roles in the explanations of these phenomena. Our numerical studies are backed up by detailed analytical considerations.

description: This paper treats the dynamics and scattering of a model of coupled oscillating systems, a finite dimensional one and a wave field on the half line. The coupling is realized producing the family of selfadjoint extensions of the suitably restricted self-adjoint operator describing the uncoupled dynamics. The spectral theory of the family is studied and the associated quadratic forms constructed. The dynamics turns out to be Hamiltonian and the Hamiltonian is described, including the case in which the finite dimensional systems comprises nonlinear oscillators; in this case the dynamics is shown to exist as well. In the linear case the system is equivalent, on a dense subspace, to a wave equation on the half line with higher order boundary conditions, described by a differential polynomial $p(\partial_x)$ explicitely related to the model parameters. In terms of such structure the Lax-Phillips scattering of the system is studied. In particular we determine the incoming and outgoing translation representations, the scattering operator, which turns out to be unitarily equivalent to the multiplication operator given by the rational function $-p(iκ)^*/p(iκ)$, and the Lax-Phillips semigroup, which describes the evolution of the states which are neither incoming in the past nor outgoing in the future.
Precipitation scatter interference on communication links with emphasis on the melting-snow layer
Creators: name: Hulays, Rafeh Ahmad
Publisher: name: University of British Columbia
Year: 2008

description: A geometrical model has been developed to calculate hydrometeor interference between different microwave systems sharing the same frequency. The model is capable of calculating the interference for any combination of transmitter-receiver geometry and the program is flexible enough to allow for many assumptions related to the spatial and vertical structure of the rain cell. Furthermore, it can easily accommodate different attenuation and scattering models. The study also focuses on the melting-snow layer and it is found that this layer plays a significant role in the interference calculations. The melting layer significantly increases the interference in the 1-8 GHz range, and moderately in the 8-12 GHz. On the other hand, the melting layer results in a significant decrease in the interference level at higher frequencies, especially in the 30-40 GHz range. The study also examines the effect of the ice/snow region above the melting layer and it is concluded that this region plays an important role in the interference calculations, especially at higher frequencies. Three examples of interference geometries are examined in Chapter 4. The first deals with the interference from an up-link to terrestrial links in the near-forward direction, the second deals with the interference from an up-link to terrestrial links in the near-backward direction and the third deals with the interference from an up-link to a satellite in the forward direction. A comparison is made between two rain-cell models in Chapter 5. The COST 210 rain-cell model, which is adopted by the CCIR (International Radio Consultative Committee), is compared with the more physical Capsoni rain-cell model. A new empirical attenuation formula for rain and melting-snow has been developed, which, unlike previous formulae, has the frequency as a separate parameter. For detailed analysis, refer to Appendix D.

description: A recently developed treatment of stochastic processes leads to the construction of a potential landscape for the dynamical evolution of complex systems. Since the existence of a potential function in generic settings has been frequently questioned in literature,herewe study several related theoretical issues that lie at core of the construction. We showthat the novel treatment,via a transformation,is closely related to the symplectic structure that is central in many branches of theoretical physics. Using this insight, we demonstrate an invariant under the transformation. We further explicitly demonstrate, in one-dimensional case, the contradistinction among the new treatment to those of Ito and Stratonovich, as well as others.Our results strongly suggest that the method from statistical physics can be useful in studying stochastic, complex systems in general.

description: We propose and analyse a scheme to cool atoms in an optical lattice to ultra-low temperatures within a Bloch band, and away from commensurate filling. The protocol is inspired by ideas from dark state laser cooling, but replaces electronic states with motional levels, and spontaneous emission of photons by emission of phonons into a Bose-Einstein condensate, in which the lattice is immersed. In our model, achievable temperatures correspond to a small fraction of the Bloch band width, and are much lower than the reservoir temperature.

description: We study the average entanglement entropy of blocks of contiguous spins in aperiodic XXZ chains which possess an aperiodic singlet phase at least in a certain limit of the coupling ratios. In this phase, where the ground state constructed by a real space renormalization group method, consists (asymptotically) of independent singlet pairs, the average entanglement entropy is found to be a piecewise linear function of the block size. The enveloping curve of this function is growing logarithmically with the block size, with an effective central charge in front of the logarithm which is characteristic for the underlying aperiodic sequence. The aperiodic sequence producing the largest effective central charge is identified, and the latter is found to exceed the central charge of the corresponding homogeneous model. For marginal aperiodic modulations, numerical investigations performed for the XX model show a logarithmic dependence, as well, with an effective central charge varying continuously with the coupling ratio.
