Neutral gas density in Damped Lyman Alpha systems

description: We estimate the intrinsic neutral gas density in Damped Lyman Alpha systems ($Ω_{HI}^{(DLA)}$) in the redshift range $ 2.2 \lesssim z \lesssim 5$ from the DLA SDSS DR_3 sample of optically selected quasars. We take into account self-consistently the obscuration on background quasars due to the dust present in Damped Lyman Alpha systems. We model the column density and redshift distribution of these systems by using both a non-parametric and a parametric approach. Under conservative assumptions on the dust content of Damped Lyman $α$ systems, we show that selection effects lead to underestimating the intrinsic neutral gas density by at least $15\%$ with respect to the observed neutral gas density. Over the redshift range $[2.2;5.5]$ we find $Ω_{HI}^{(DLA)}=0.97^{+0.08+0.28}_{-0.06-0.15} \cdot 10^{-3}$, where the first set of error bars gives the $1σ$ random errors and the second set gives the modeling uncertainty dependent on the fraction of metals in dust - from 0\% to 50\%. This value compares with $Ω_{HI}^{(DLA)}=0.82^{+0.05}_{-0.05}$ ($1σ$ error bars), which is obtained when no correction for dust is introduced. In the model with half of the metals mass in dust we cannot constraint $Ω_{HI}^{(DLA)}$ at a confidence level higher than $90\%$. In this case there is indeed a probability of about $10\%$ that the intrinsic column density distribution of DLA systems is a power law $f(N_{HI}) \propto 1/N_{HI}^{~1.95}$. In contrast, with $25 \%$ of the metals in dust - the most realistic estimate - a power law is ruled out at $99.5\%$ of confidence level.

Sandwich panel

description: This work analyzed multi length-scale composites from an experimental and modeling perspective. Three main experiments were conducted: fatigue of foam and pin-reinforced foam cores, indentation prevention using load spreaders, and nanotube reinforcement for increased interlaminar strength. A method for determining cycles to failure for a sandwich panel was established using an empirical model. The fatigue response is captured by conducting experiments at varying stress levels to determine empirical constants. Stress-softening is observed in 92% of tests under varying fatigue cases, even at low stress amplitudes. A stiffness criterion can be developed to estimate failure such that once a reduced level of stiffness is reached a structure is removed from service. For load spreaders numerical models showed that a stress concentration develops under the corner of the load spreader. In light of this, a triangular collapse model was derived using a work balance. The model was found to predict the collapse load within 20 N or 12% of the failure load. For design purposes the model allows the minimum spreader dimension to be determined by inputting the expected load on a joint. Carbon nanotubes were grown on the surface of carbon and glass fibers using CVD. The heat of the reaction and exposure to high temperature were limited to prevent fiber damage. Nanotubes longer than two times the fiber diameter negatively impact the fiber volume fraction which reduces interlaminar strength, but high densities of short nanotubes improve interlaminar strength. Gains of up to 29.4 % were seen in glass, 56.2 % were seen in Grafil and 36.2 % were seen in IM7.

description: Carbon nano-structures were grown onto the surfaces of two glass fiber substrates and a carbon fiber substrate using an in-line continuous chemical vapor deposition-based growth chamber. The growth system-related processing parameters, specifically growth chamber temperature, catalyst concentration and process line speed, were varied to observe the effect on the mechanical properties and dry tow bundle behavior of each substrate. Dry fiber tow bundle level tensile tests were conducted on As-Received and processed fiber tow bundles. A statistically significant number of tests were used to determine the distribution of mechanical material properties, including, but not limited to, stiffness, max load, and failure strain. The test results provide the necessary statistical information to analysis the dry fiber tow bundle behaviors using Weibull analysis. The findings of this study are used to identify the most fruitful processing paths for these emerging materials.

description: The excessive travel demand in the metro system during peak hours may cause platform congestion and reduce the comfort of the passengers. Thus, this article proposes an approach for integrally optimizing the train timetable and passenger control on an oversaturated metro line, to improve the comfort of passengers on the platform. Specifically, taking the short-term impact of the boarding/alighting passengers into account, a novel quantitative assessment method of the perceived waiting time, considering the impact of the platform passengers’ density and passenger control strategy, named the generalized waiting time, is proposed. A mixed-integer nonlinear programming model is formulated to minimize the generalized waiting time, and a heuristic algorithm based on the adaptive simulated annealing genetic algorithm and the adaptive large neighbourhood search (ASAGA-ALNS) is designed to find high-quality solutions. The results of numerical experiments show that the method can alleviate platform congestion, while improving the comfort of waiting passengers.
Changing the Mechanical Properties of PMMA Bone Cement with Nano and Micro Particles

description: Total joint arthroplasty is a highly successful way to restore pain free function to patients afflicted with arthritis. Poly(methylmethacrylate) (PMMA) bone cement is commonly used as a fixing agent in artificial joints. The historical success rate on patients over 60 years (in a ten year time frame) exceeds 90%. Loosening is often preceded by the fracture of the bone cement, which will inevitably lead to a prosthesis failure and require a revision surgery. Bone cement used for total joint surgeries has not changed significantly since first introduced in the 1960's. This research seeks to improve the fracture resistance of bone cement by introducing changes in the fundamental microstructure of the cement, thus increasing the fracture resistance of bone cement and the life of the artificial joint. Novel cements were created by replacing a percentage (10%) of the solid phase using 4 different additives. Fracture toughness tests were performed as the primary indicator of improved mechanical performance. The cross-linked additives showed an increase of 33% when compared to the fracture toughness of the control group. Scanning Electron Microscope (SEM) imaging and nanoindentation were used to further characterize the properties of the new bone cements. This research suggests that the fracture properties of existing bone cement may be improved by microstructural changes. Such changes may eliminate or reduce bone cement failure and thereby prevent prosthesis failures that require costly revision surgeries. The ultimate outcome of this research is to improve the quality of life for people with arthritis.

description: We seek to resolve the tension in the literature regarding the presence of radially segregated multiple populations in Galactic globular cluster M13. Previous studies of this nearby cluster have presented discordant results about the degree of dynamical mixing in M13's inner region. Using ground-based (UBVI) photometry, we show that cumulative radial distributions of stars on the blue and red sides of the red giant branch are statistically identical. Interestingly, these results are obtained using data from large-aperture, ground-based telescopes as well as a more modestly-sized instrument, and both are in agreement with previous work done using HST and Stromgren photometry. Results are derived using the C_{U,B,I} index, shown to be sensitive to compositional differences. We discuss our conclusions that the chemically distinct populations within M13 may be dynamically mixed in the context of published results from simulations.

Subjects: diffusion

description: Typical hydrogels used in tissue engineering applications inhibit the diffusion of large molecular weight molecules, such as growth factors.  The mass transport of these large molecular weight molecules is vital to cell viability within the gels.   Macroporous hydrogels are a solution to this poor protein diffusion.  However, current macroporous hydrogels are formed under harsh or toxic conditions limiting their application.  This work outlines a procedure in which macroporous hydrogels are formed via the enzymatic degradation of embedded carboxymethyl cellulose (CMC) microspheres.  These microspheres were formed via emulsion polymerization of methacrylated CMC using ammonium persulfate (APS) and N,N,N',N'-tetramethylethylenediamide (TEMED) as in initiator system.  In addition, protein diffusion experiments were conducted using the model proteins, cellulase and bovine serum albumin (BSA), for both macroporous and control PEG-DM hydrogels. It was found that convective mass transport within the macropores dramatically increased the mass transport of these model proteins through the gels.

description: This study was designed to expand the understanding of the undergraduate UMBC Mechanical Engineering Department Collection experience as it relates to having a formal mentoring program. To assess this relationship, qualitative analysis was used to derive themes and define variables that contribute to the success of the student. Using a 17-item Likert survey, the undergraduate UMBC Mechanical Engineering Department Collection student population was assessed based on their attitudes and impressions on each of the variables. Using the data acquired from this survey, descriptive and inferential statistics were utilized to identify significant relationships between the formal mentoring groups, Center for Women in Technology (CWIT), Meyerhoff Scholars and non-programmed, and the variables. The data show that factors other than academics play a role in a student`s decision to be involved in UMBC Mechanical Engineering Department Collection. It is evident that the formal mentoring group has encouraged different attitudes in their students in comparison to non-programmed students. Meryerhoff students are significantly more motivated by mentor influences than CWIT and non-programmed. Non-programmed students feel significantly less inclusive and are more motivated by parent influence. Both the formal mentoring programs have a higher perception of the importance of professional and interpersonal skills in comparison to non-programmed students. Student`s overall impressions of advising were low. It is recommended to the department of UMBC Mechanical Engineering Department Collection to create clear expectations in advising roles and consider adopting some formal mentoring practices, i.e. peer mentoring.

description: The differential cross section and analyzing power $A_y$ of the ${\vec p}p{\to}ppπ^0$ reaction have been measured at RCNP in coplanar geometry at a beam energy of 390 MeV and the dependence on both the pion emission angle and the relative momentum of the final protons have been extracted. The angular variation of Ay for the large values of the relative momentum studied here shows that this is primarily an effect of the interference of pion s- and p-waves and this interference can also explain the momentum dependence. Within the framework of a very simple model, these results would suggest that the pion-production operator has a significant long-range component.

description: This paper summarizes the project work on asteroseismology at the ERASMUS+ GATE 2020 Summer school on space satellite data. The aim was to do a global asteroseismic analysis of KIC 5006817 and quantify its stellar properties using the high-quality, state of the art space missions data. We employed the aperture photometry to analyze the data from the Kepler space telescope and the Transiting Exoplanet Survey Satellite (TESS). Using the lightkurve Python package, we have derived the asteroseismic parameters and calculated the stellar parameters using the scaling relations. Our analysis of KIC 5006817 confirmed its classification as a heartbeat binary. The rich oscillation spectrum facilitate estimating power excess ($ν_{\rm max}$) at 145.50$\pm$0.50 $μ$Hz and large frequency separation ($Δν$) to be 11.63$\pm$0.10 $μ$Hz. Our results showed that the primary component is a low-luminosity, red-giant branch star with a mass, radius, surface gravity, and luminosity of 1.53$\pm$0.07 M$_\odot$, 5.91$\pm$0.12 R$_\odot$, 3.08$\pm$0.01 dex, and 19.66$\pm$0.73 L$_\odot$, respectively. The orbital period of the system is 94.83$\pm$0.05 d.

description: We report the ubiquitous occurrence of nighttime temperature inversions in the tropical martian atmosphere during the dusty season, as observed by the Mars Climate Sounder. The inversions are linked to the occurrence of large-scale regional dust storms, with their strengths largely correlated to the strengths of the dust storms. Inversions strengthen between 2 am and 4 am, with the bases of the inversions getting cooler, and the tops of the inversions getting warmer. The inversions are strongest around Tharsis and Terra Sabaea, which are higher-elevation regions, suggesting they are forming due to a combination of topographically-excited tides and cloud radiative cooling. However, inversions are also observed over the flat plains, and are likely associated with stronger tides resulting from the increased dust abundance. These results highlight an important interplay between the dust distribution, water ice clouds and thermal tides.

description: Efimov physics refers to universal phenomena associated with a discrete scaling symmetry in the 3-body problem with a large scattering length. The first experimental evidence for Efimov physics was the recent observation of a resonant peak in the 3-body recombination rate for 133Cs atoms with large negative scattering length. There can also be resonant peaks in the atom-dimer relaxation rate for large positive scattering length. We calculate the atom-dimer relaxation rate as a function of temperature and show how measurements of the relaxation rate can be used to determine accurately the parameters that govern Efimov physics.

We use the form factor bootstrap supplemented by asymptotic conditions to determine its matrix elements in the sinh-Gordon model. The results extend to the breather sector of the sine-Gordon model and to the minimal models M_{2/(2N+3)} perturbed by the operator phi_{1,3}.

description: We study top quark flavor violation in the framework of a warped extra dimension with the Standard Model (SM) fields propagating in the bulk. Such a scenario provides solutions to both the Planck-weak hierarchy problem and the flavor puzzle of the SM without inducing a flavor problem. We find that, generically, tcZ couplings receive a huge enhancement, in particular the right handed ones can be O(1%). This results in BR(t -> c Z) at or above the sensitivity of the Large Hadron Collider (LHC). At the International Linear Collider (ILC), single top production, via e^+ e^- -> t \bar c, can be a striking signal for this scenario. In particular, it represents a physics topic of critical importance that can be explored even with a relatively low energy option, close to the tc threshold. At both the LHC and the ILC, angular distributions can probe the above prediction of dominance of right-handed couplings.

description: Radio core dominance measurements, an indicator of jet orientation, sometimes rely on core flux density measurements from large-area surveys like Faint Images of the Radio Sky at Twenty cm (FIRST) that have an angular resolution of only 5''. Such low-resolution surveys often fail to resolve cores from the extended emission resulting in an erroneous measurement. We focus on investigating this resolution effect for a sample of 119 radio-loud quasars. We obtained continuum observations from NSF's Karl G. Jansky Very Large Array (VLA) at 10 GHz in A-array with a 0.2'' resolution. Our measurements show that at FIRST spatial resolution, core flux measurements are indeed systematically high even after considering the core-variability. For a handful of quasars, 10 GHz images reveal extended features, whereas the FIRST image shows a point source. We found that the resolution effect is more prominent for quasars with smaller angular sizes. We further computed two radio core dominance parameters R & R5100 for use in statistical orientation investigations with this sample. We also present the spectral energy distributions between 74 MHz and 1.4 GHz, which we used to measure the spectral index of the extended emission of these quasars. Our results empirically confirm that determination of radio core dominance requires high-spatial resolution data. We highlight the practical issues associated with the choice of frequency and resolution in the measurement of core and extended flux densities.

description: We say that a Cellular Automata (CA) is coalescing when its execution on two distinct (random) initial configurations in the same asynchronous mode (the same cells are updated in each configuration at each time step) makes both configurations become identical after a reasonable time. We prove coalescence for two elementary rules and show that there exists infinitely many coalescing CA. We then conduct an experimental study on all elementary CA and show that some rules exhibit a phase transition, which belongs to the universality class of directed percolation.

description: The recording of respiratory sounds was of significant benefit in the diagnosis of abnormalities in respiratory sounds. The duration of the sounds used in the diagnosis affects the speed of the diagnosis. In this study, the effect of window size on diagnosis of abnormalities in respiratory sounds and the most efficient recording time for diagnosis were analyzed. First, window size was applied to each sound in the data set consisting of normal and abnormal breathing sounds, 0.5 second and from 1 to 20 seconds Increased by 1 second. Then, the data applied to window size was inferred feature extraction with Mel Frequency Cepstral Coefficient (MFCC) and the performance of each window was calculated using the leave one-out classifier and the k-nearest neighbor (KNN) algorithm. As a result, it was determined that the data was significant with an average performance of 92.06% in the records between 2 and 10 seconds.

For six groups, the fixed point set of a noncentral involution is shown to be equivariantly homotopy equivalent to a standard geometry for the component of the centralizer. For odd primes, fixed point sets are computed for sporadic groups having an extraspecial Sylow p-subgroup of order p^3, acting on the complex of those p-radical subgroups containing a p-central element in their centers. Vertices for summands of the associated reduced Lefschetz modules are described.

description: The Fergana Valley is considered a hotspot for water conflicts – not only within Central Asia but also at the level of global politics. By using the water of the Syr-Darya river and its tributaries, an enormous irrigation system was built up in the Fergana region – a valley formerly characterised by deserts and river oases. This led to the creation of one of the largest cotton growing regions in the world. At present, the system supplies one of the most densely populated regions in Central Asia with water. Huge dam cascades also produce a significant amount of electricity. This has led to disagreements and conflicting interests between upstream and downstream countries. Experiences in many parts of the world have shown that a purely technical approach to solving waterrelated problems has not always brought about the desired results. In many cases, it even had negative implications for society and environment. Therefore, improved management strategies and integrated policies are needed for dissolving the existing “path dependencies” that limit the range of development options and confine the scope of action available to the Fergana region. The interdisciplinary research group “Society – Water – Technology” at the Berlin-Brandenburg Academy of Sciences and Humanities has dedicated itself to this issue and aims at providing scientific policy advice to decision-makers and stakeholders.

description: We predict the robust existence of a novel quantum orbital stripe order in the $p$-band Bose-Hubbard model of two-dimensional triangular optical lattices with cold bosonic atoms. An orbital angular momentum moment is formed on each site exhibiting a stripe order both in the superfluid and Mott-insulating phases. The stripe order spontaneously breaks time-reversal, lattice translation and rotation symmetries. In addition, it induces staggered plaquette bond currents in the superfluid phase. Possible signatures of this stripe order in the time of flight experiment are discussed.

Falling balls in a viscous fluid with contact: Comparing numerical simulations with experimental data

description: We evaluate a number of different finite element approaches for fluid-structure (contact) interaction problems against data from physical experiments. For this we take the data from experiments by Hagemeier [Mendeley Data, doi: 10.17632/mf27c92nc3.1]. This consists of trajectories of single particles falling through a highly viscous fluid and rebounding off the bottom fluid tank wall. The resulting flow is in the transitional regime between creeping and turbulent flows. This type of configuration is particularly challenging for numerical methods due to the large change of the fluid domain and the contact between the wall and particle. In the numerical simulations we consider both rigid body and linear elasticity models for the falling particles. In the first case, we compare results obtained with the well established Arbitrary Lagrangian Eulerian (ALE) approach and a moving domain CutFEM method together with a simple and common approach for contact avoidance. For the full fluid-structure interaction (FSI) problem with contact, we use a fully Eulerian approach in combination with a unified FSI-contact treatment using Nitsche's method. For higher computational efficiency we use the geometrical symmetry of the experimental set up to reformulate the FSI system into two spatial dimensions. Finally, we show full three dimensional ALE computations to study the effects of small perturbations in the initial state of the particle to investigate deviations from a perfectly vertical fall observed in the experiment. The methods are implemented in open-source finite element libraries and the results are made freely available to aide reproducibility.
Meson Strings and Flavor Branes

description: In a QCD-like string model based on D6 flavor branes in the presence of D4 color branes wrapping one of the compactified dimension on an $S^1$, the shape of meson strings in the five dimensional curved space as well as the potential between quark and anti-quark are investigated. The flavor branes on which both ends of a meson string live are assumed to be separated in this five dimensional space, depending on the values of the constituent quark masses. It is shown in this picture that the meson string with different flavors on both ends changes its shape at a critical distance. There is, however, no critical distance for the meson with the same flavors. At this critical distance the potential between quark and anti-quark with different flavors gives a point of reflection and changes its shape around this point. Accordingly, the attractive force between quark and anti-quark seems to become stronger when the distance of flavor branes connecting meson strings becomes larger. This indicates quark systems with different flavors can form high-density states.

description: The axion, a hypothetical elementary pseudoscalar, is expected to solve the strong CP problem of QCD and is also a promising candidate for dark matter. The most sensitive axion search experiments operate at millikelvin temperatures and hence rely on instrumentation that carries signals from a system at cryogenic temperatures to room temperature instrumentation. One of the biggest limiting factors affecting the parameter scanning speed of these detectors is the noise added by the components in the signal detection chain. Since the first amplifier in the chain limits the minimum noise, low-noise amplification is of paramount importance. This paper reports on the operation of a flux-driven Josephson parametric amplifier (JPA) operating at around 2.3 GHz with added noise approaching the quantum limit. The JPA was employed as a first stage amplifier in an experimental setting similar to the ones used in haloscope axion detectors. By operating the JPA at a gain of 19 dB and cascading it with two cryogenic amplifiers operating at 4 K, noise temperatures as low as 120 mK were achieved for the whole signal detection chain.
Small Scale Systems of Galaxies. III. X-ray detected E+S galaxy pairs in low density environments

description: We present a comprehensive study of the local environments of four E+S galaxy pairs with the main goal to investigate their formation/evolution histories. New XMM-Newton data were obtained for two pairs (RR 143 and RR 242) that complements existing ROSAT data for the other two (RR 210 and RR 216). The new observations reveal diffuse X-ray emission in both pairs. The emission is asymmetric in both cases and extends out to 120 kpc and 160 kpc in RR 143 and RR 242 respectively. The nucleus of RR 242 hosts a low luminosity mildly absorbed AGN. We find that the early-type components of pairs with diffuse hot gas appear to be relaxed objects while those in RR 210 and RR 216, where no diffuse emission has been found, display unambiguous signatures of ongoing interaction. Wide-field V and R-band data are used to study the photometric properties of the early-type components and to search for a candidate faint galaxy populations around each of the pairs. While no diffuse optical light is found for any of the pairs, all of the early-type members show very extended and concentric luminous envelopes. We identify a faint galaxy sample in each field and we consider whether they could be physically associated with the luminous pairs based upon (V-R) colors and photometric properties. We find that the distribution of r_e and M_R for the candidates are similar in three of the fields (RR 143, 216 and 242). The same selection criteria applied to the field of RR 210 suggest a fainter and more compact population possibly suggesting a larger background fraction than in the other fields.

Microscopic Entropy of AdS$_3$ Black Holes Revisited

Year: 2021
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We revisit the microscopic description of AdS$_3$ black holes in light of recent progress on their higher dimensional analogues. The grand canonical partition function that follows from the AdS$_3$/CFT$_2$ correspondence describes BPS and nearBPS black hole thermodynamics. We formulate an entropy extremization principle that accounts for both the black hole entropy and a constraint on its charges, in close analogy with asymptotically AdS black holes in higher dimensions. We are led to interpret supersymmetric black holes as ensembles of BPS microstates satisfying a charge constraint that is not respected by individual states. This interpretation provides a microscopic understanding of the hitherto mysterious charge constraints satisfied by all BPS black holes in AdS. We also develop thermodynamics and a nAttractor mechanism of AdS$_3$ black holes in the nearBPS regime.
