description: Objective: The tibia is the most commonly fractured long bone in a pedestrian-vehicle collision. The standard injury assessment tool is the “legform,” a device that mimics the human lower limb under impact loads. These devices are designed to identify the impact load that will cause the onset of injury, rather than replicate the type and severity of fracture. Thus, this study is the first to determine if composite tibias made by Sawbones (Pacific Research Labs, Vashon, WA, USA) designed for orthopedic biomechanics research, could also potentially be used for traffic safety research by simulating both the damage tolerance of human cadaveric tibias for peak force and bending moment and the fracture patterns themselves, thereby more accurately predicting injury type during real-world pedestrian-vehicle collisions. Methods: Synthetic tibias (n = 6) and human cadaveric tibias (n = 6) were impacted at midshaft at 8.3 m/s (i.e., 30 km/h) under 3-point bending using a pneumatic impacting apparatus. Fracture force, bending moment, and fracture patterns were compared between the two groups, and Weibull survivability curves generated for force and moment results, to identify injury risk thresholds. Results: There was no difference for synthetic vs. cadaveric tibias regarding impact force (4271+/-938 N vs. 4889+/-993 N, p = 0.44) or bending moment at fracture (275+/-64 Nm vs. 302+/-107 Nm, p = 0.69). Force-time curves for all tibias were similar in shape based on the first three Principal Components (p > 0.14). Weibull survivability curves had differences in shape and in the 10% risk of fracture limits, with force thresholds of 2873 N for the synthetic vs. 3386 N for the cadaveric, and bending moment limits of 180 Nm for the synthetic compared to 157 Nm for the cadaveric. All fracture patterns were clinically realistic, but not consistent between groups. The coefficient of variation for synthetic tibias was >0.2 for both peak force and bending moment, which precludes their use as a reproducible test surrogate for injury prediction. Conclusions: Synthetic composite tibias offer the potential for developing a frangible test surrogate, and matched cadaveric response in several respects. However, the repeatability was not high enough for them to be used in their present form for injury prediction.

description: The main objective of this IAEI internal research project was to assess what factors influence drawing of subsidies from the 3rd and 4th Axis Rural Development Programme in the Czech Republic over the period 2007 – 2013. We analyse factors of rural development and employ a questionnaire survey. One part concentrates on quantitative analysis and assesses available data on factors of development on the level of municipality (village), categorised by individual measures of the Rural Development Programme 2007 – 2013 in Axes 3 and 4 (from 2007 through June 2013). The other part considers selected municipalities and their successful applicants. Results of the analysis of available data showed that the statistical methods did not produce sufficient explanation of factors that affect the utilization of grant funds for measures of Axis 3 and 4. Quantitative approach is suitable for a general categorization of territorial monitor progress. For an explanation of the factors that influence the utilization of grant funds is necessary qualitative investigation, such as questionnaires. The questionnaire showed that the initial information about the project is being received almost exclusively randomly. Therefore, it is recommended to increase promotion of public awareness of rural development measures in next period (2014-2020).

description: The Space Variable Object Monitor (SVOM) is a forthcoming Chinese - French astrophysics space mission dedicated to the study of Gamma-ray bursts and high-energy transients. ECLAIRs, a wide-field hard X-ray coded mask imager, is the leading instrument for the transient detection and their first localisation. The sensitivity of such instruments is usually limited by the background, either of instrumental or astrophysical origin. Detailed estimations of the background are obtained by simulating the interaction of particles with the matter using, in the present case, the GEANT4 Monte-Carlo toolkit. However, this is a time consuming process, especially when it is needed to carry out all possible geometrical and orbital configurations. Instead, we present a much faster method that allows computing the background in either a static or dynamic (time dependent) way. The method is based on the preliminary calculation of a large particle database using the GEANT4 toolkit followed by a selection process based on the incoming direction and energy of the particles. This approach is as accurate as direct Monte-Carlo methods, while it reduces the computation time by a factor of $10^3 - 10^4$ for our application. We apply this method to compute the SVOM/ECLAIRs dynamic background.

description: The pentaquark states, $P_{c}(4312)$, $P_{c}(4440)$ and $P_{c}(4450)$, can be nicely arranged into a multiplet of seven molecules of $\bar{D}^{(\ast)}Σ_{c}^{(\ast)}$ dictated by heavy quark spin symmetry, while the $Ξ_{cc}^{(\ast)}Σ_{c}^{(\ast)}$ system can be related to the $\bar{D}^{(\ast)}Σ_{c}^{(\ast)}$ system via heavy antiquark diquark symmetry. In this work we employ the one boson exchange model to study the interactions between $Ξ_{cc}^{(\ast)}$ and $Σ_{c}^{(\ast)}$ with constraints from the pentaquark system. We show that a multiplet of ten triply charmed dibaryons emerge naturally in the isospin-1/2 sector, while only three appear in the isospin-3/2 sector. In addition, we study their heavy quark flavor partners. Ten triply bottom diybaryons are found in the isospin-1/2 sector, while only nine are likely in the isospin-3/2 sector. Furthermore, the predicted mass splitting between the $0^{+}$ $Ξ_{cc}Σ_{c}$ state and its $1^{+}$ counterpart is found to be consistent with the correlation implied by heavy antiquark diquark symmetry recently pointed out in Pan $et$ $al$..

description: A statistical thermodynamic approach of moving particles forming an elastic body is presented which leads to reveal molecular-mechanical properties of classical and nonextensive dynamical systems. We derive the Boltzmann-Gibbs (BG) entropy form and relate it to Newton's law of motion in relation to a distinct tensile force acting on the systems at constant volume and number of particles. Tsallis generalization of the BG entropy is deduced assuming the thermal energy of the particles to be proportional to their energy states by the nonextensivity factor q-1.

We show that, as it happens in the Null Surface Formulation of General Relativity, the Wuschmann-like condition can be obtained as a requirement of a vanishing torsion tensor. Furthermore, from these second order ODEs we obtain the associated Cartan connections.

Observation and Modelling of Starburst Driven Galactic Winds: A Review in honour of John Dyson
Creators: name: Breitschwerdt, Dieter
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Starburst galaxies are generally associated with extended X-ray and radio halos, giving a clear hint of an outflow of gas and relativistic particles from the disk into the halo. The driving agents are, not surprisingly, active star forming regions, injecting hot gas and cosmic rays generated by supernova remnant and superbubble shock waves. The dynamics of the outflow and the thermal evolution of the plasma are strongly coupled, and therefore a self-consistent model is necessary for a satisfactory description. Since the plasma temperature is between one and a few million Kelvin, the halo is most conspicuous in soft X-rays. It will be shown that X-ray data obtained recently with XMM-Newton EPIC pn bear clear spectral signatures that are in strong disagreement with an isothermal halo in collisional ionization equilibrium (CIE). Instead a temperature structure in X-ray halos is observed. It will be demonstrated that a galactic wind outflow model in which the non-equilibrium ionization structure is calculated self-consistently can give a satisfactory and physical explanation for the X-ray spectral characteristics, e.g. in case of the local starburst galaxy NGC 3079. In particular, high subsolar abundances, that have been reported from X-ray observations in some cases, are shown to be artefacts of CIE spectral fit models. It is found that spectral models are strongly constrained by the presence of diagnostic lines such as OVII and OVIII as well as Fe-L line complexes. Thus a detailed spectral X-ray model will help to provide important galactic wind parameters, such as mass loss rate and velocity profile, which may also serve as valuable input for galactic outflows in the early universe.

description: The aim of the empirical research was to determine the degree of social cohesion on the basis of the perception of the specifics of the modern countryside (which is undergoing disagrarisation) and the values of rural environment. The case study illustrates selected social consequences of spatial policy regarding housing in rural communes in the suburban area of a big city (case of Metropolitan Area of Łódź). Unlike macro-scale studies, both Polish and foreign, micro-scale studies have shown that differences are even greater and concern neighbouring areas. The different ways of life are manifested in different behaviour patterns and levels of territorial identity. New residents of a village perceive space primarily in terms of functional utility (convenience of residence), while long-time residents attach sentimental value to it, due to historical continuity. In such a case, special attention is paid to social and spatial behaviour patterns stemming from the historical continuity of certain individual characteristics of functioning within a local structure.

description: We propose an action for gravity on a fuzzy sphere, based on a matrix model. We find striking similarities with an analogous model of two dimensional gravity on a noncommutative plane, i.e. the solution space of both models is spanned by pure U(2) gauge transformations acting on the background solution of the matrix model, and there exist deformations of the classical diffeomorphisms which preserve the two-dimensional noncommutative gravity actions.

Over-constrained Gravitational Lens Models and the Hubble Constant

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: It is well known that measurements of H0 from gravitational lens time delays scale as H0~1-k_E where k_E is the mean convergence at the Einstein radius R_E but that all available lens data other than the delays provide no direct constraints on k_E. The properties of the radial mass distribution constrained by lens data are R_E and the dimensionless quantity x=R_E a''(R_E)/(1-k_E)$ where a''(R_E) is the second derivative of the deflection profile at R_E. Lens models with too few degrees of freedom, like power law models with densities ~r^(-n), have a one-to-one correspondence between x and k_E (for a power law model, x=2(n-2) and k_E=(3-n)/2=(2-x)/4). This means that highly constrained lens models with few parameters quickly lead to very precise but inaccurate estimates of k_E and hence H0. Based on experiments with a broad range of plausible dark matter halo models, it is unlikely that any current estimates of H0 from gravitational lens time delays are more accurate than ~10%, regardless of the reported precision.

description: Objective: The proliferation of electric scooter sharing companies has inundated many municipalities with electric scooters. The primary objective of this study is to characterize the epidemiology of injuries from this new mode of transportation in order to inform injury prevention efforts. Methods: A multicenter, retrospective study was conducted at two level 1 trauma centers in an urban setting. Patients seen in the emergency department from September 4, 2018 to November 4, 2018 were included if injury coding and chart review identified a scooter-related injury. Demographics, injury patterns, and other injury related factors were obtained via chart review. Results: Ninety-two patients were identified over the study period in 2018 with electric scooter-related injuries. Of the patients utilizing an electric scooter; none used protective gear and 33% used alcohol prior to presentation. More than 60% of patients required medical intervention including laceration repair (26%), fracture reduction (17%), operative fixation of a fracture (7%), or arterial embolization for an associated arterial injury (1%). Approximately 10% of patients required inpatient admission and one required an admission to the intensive care unit. Conclusion: We found a substantial increase in the number of scooter-related injuries during the first two months of electric scooter legalization. There was a lack of safety equipment utilization and concomitant alcohol utilization was common. These may offer areas of focus for injury prevention efforts. Additionally, standardization of injury coding for electric scooter related injury is critical to future studies and will help better understand the impact of this new mode of transportation.

description: The neutron star equation of state is now being constrained from a diverse set of multi-messenger data, including gravitational waves from binary neutron star mergers, X-ray observations of the neutron star radius, and many types of laboratory nuclear experiments. These measurements are often mapped to a common domain for comparison with one another or are used to constrain the predictions of theoretical equations of state. We explore here the statistical biases that can arise when such multi-messenger data are compared or combined across different domains. We find that placing Bayesian priors individually in each domain of measurement can lead to biased constraints. We present a new prescription for defining Bayesian priors consistently across different experiments, which will allow for robust cross-domain comparisons. Using the first two binary neutron star mergers as an example, we show that a uniform prior in the tidal deformability can produce inflated evidence for large radii, while a uniform prior in the radius points towards smaller radii. Finally, using this new prescription, we provide a status update on multi-messenger constraints on the neutron star radius.

description: Despite the decline in daily commutes amid the COVID-19 pandemic, many individuals still engage in regular commuting, whether by car, public transit, or active modes of transportation. These daily journeys provide structure and routine, offering a sense of stability and distinction between various aspects of our lives. However, in societies heavily reliant on cars, longer commute times contribute to environmental damage and decreased physical activity. The crucial factor is not the act of commuting but how we choose to commute. Access to nature and physical activity are vital to our well-being, highlighting the necessity for a more harmonious relationship between urban environments, nature, and alternative transportation methods. Creating a therapeutic commuting experience could prove more beneficial for individuals.

description: We consider a strongly interacting twin Higgs (SITH) model where an ultraviolet completion of twin Higgs mechanism is realized by a strongly coupled approximately scale invariant theory. Besides the Standard Model (SM) and twin sectors, the low energy effective theory contains a relatively light scalar called a dilaton --- the pseudo Goldstone boson of spontaneously broken scale invariance. The dilaton provides a unique portal between the SM and twin sectors whose phenomenology could provide an important probe of the twin Higgs mechanism. As a concrete example, we consider a holographic twin Higgs model where the role of the dilaton is played by the radion. The phenomenology of this model is fully determined by a few parameters and our analysis concludes that at the HL-LHC (14 TeV) and HE-LHC (27 TeV) with 3000/fb most of the natural parameter space can be probed.

description: Objective(s): 1) to determine whether the proportion of alcohol-impaired patients involved in motor vehicle crashes (MVCs) varies by race/ethnicity within different age groups; 2) to explore the relationship between alcohol impairment, race/ethnicity and clinical outcomes among patients involved in MVCs across age groups. Methods: The 2012 National Trauma Data Bank (NTDB) queried for patients aged 16–55 involved in MVCs who received a blood ethanol test on admission. Results: Of the 44,216 patients involved in MVC, 68% were White, 14% Black, and 13% were Hispanic. About 36% were 16–25 years old, and 19% were 46–55 years old. Alcohol-impaired patients constituted 34% of the patients. The multiple logistic regression analysis of HLOS ≥ 2 days revealed that, when controlling for age, gender, race/ethnicity, insurance status, and the interaction between alcohol impairment and age as well as alcohol impairment and race/ethnicity, alcohol impairment positivity carried a 15% increase in probability of HLOS ≥ 2 days (OR 1.15, p < 0.0001). Additionally, using the 16–25 age group as reference, each of the older age groupings showed an increased probability of HLOS ≥ 2 days with ORs of 1.15, 1.32, and 1.51 for ages 26–35, 36–45, and 46–55, respectively (p-values < 0.0001). Blacks, Hispanics, and Asians/others were less likely than Whites to have HLOS ≥ 2 days with OR of 0.88, 0.89, and 0.88, respectively (p < 0.05). There was no statistically significant difference in the clinical outcome of mortality between races/ethnicities and alcohol-impaired driving. Conclusions: This study demonstrates that the proportions of alcohol-impaired driving and the associated clinical outcomes vary among race/ethnic groups in different age groups. More research is needed to determine the reasons for the observed differences in these vulnerable sub-groups.

The actions are presented in terms of component fields up to second order in fermions. As one expects, the actions are built from the supercovariant derivative operator and the $κ$-symmetry projector. The results take a compact and elegant form exhibiting $κ$-symmetry, as well as supersymmetry in a background with Killing spinors. We give the explicit transformation rules for these symmetries in all cases, including the M2-brane. As an example, we analyze the N=2 super-worldvolume field theory defined by a test D4-brane in the supergravity background produced by a large number of D0-branes. This example displays rigid supersymmetry in a curved spacetime.

description: Weyl gravity naturally generates effective dark matter and cosmological constant terms as integration constants, eliminating the need to explicitly introduce them into the theory. Additionally, the framework permits three intriguing solutions for compact objects: an asymptotically de Sitter Schwarzschild-like black hole described by the Mannheim-Kazanas solution, a non-Schwarzschild black hole, and a traversable wormhole that exists without exotic matter. In this work, we investigate the quasinormal spectra of all three solutions.
 We demonstrate that when the mass of the black hole corresponding to the Mannheim-Kazanas solution approaches zero, the perturbation equations yield an exact solution expressible through hypergeometric functions. The quasinormal modes of black holes in Weyl gravity can be classified into three distinct branches: Schwarzschild-like modes modified by effective dark matter and cosmological terms, and modes associated with empty spacetime (de Sitter and dark matter branches), which are further influenced by the black hole mass. Previous studies have shown that the dark matter term induces a secondary stage of quasinormal ringing following the initial Schwarzschild phase. Here, we compute the frequencies using convergent methods and elucidate how this unique time-domain behavior translates into the frequency domain.
 Furthermore, we demonstrate that the non-Schwarzschild black hole can be distinguished from both the Schwarzschild-like solution and the wormhole through their distinct quasinormal spectra. We also compute shadow radii for black holes and wormholes within Weyl gravity, revealing that wormholes with large throat radii can produce significantly smaller shadows compared to black holes of equivalent mass.

description: The recent discovery of non-perturbatively stable two-dimensional string backgrounds and their dual matrix models allows the study of complete scattering matrices in string theory. In this note we adapt work of Moore, Plesser, and Ramgoolam on the bosonic string to compute the exact S-matrices of 0A and 0B string theory in two dimensions. Unitarity of the 0B theory requires the inclusion of massless soliton sectors carrying RR scalar charge as asymptotic states. We propose a regularization of IR divergences and find transition probabilities that distinguish the otherwise energetically degenerate soliton sectors. Unstable D-branes can decay into distinct soliton sectors.

description: Abstract: The objective of this research is to elaborate a proposal for the application of the Last Planner System (LPS) methodology in the planning of a medium-sized civil construction work, with repeated production scale, presenting a project, spreadsheets and weekly monitoring model. This methodology was applied as a model for planning the construction of popular 45m² houses following the same pattern. A three-level LPS sequence was used, namely Initial Planning, Lookahead Planning and Commitment Planning. The first level was a form of master planning, where the initial information of the work is collected. This level is used to facilitate the identification of the main objectives of the work and to define the rhythms of the main production process. In the second level, an adjustment is made to the initial plan and its detailing is improved, it also serves as a form of protection for production, a restriction that prevents the release of activities that do not comply with the quality criteria, controlling the release of activities of the mediumfor the short term only after analyzing and removing all possible impediments at each stage. The third level happens according to weekly work plans, in which the execution of the construction is directly guided, through the assignment of service packages to the teams, observing their commitment to carry them out. The elaborated proposal improved the process management, reduced material waste and served as a pattern for the construction of other buildings.
Chandra & XMM-Newton Observations of NGC5253. Analysis of the X-ray Emission from a Dwarf Starburst Galaxy

description: We present Chandra and XMM-Newton X-ray data of NGC5253, a local starbursting dwarf elliptical galaxy, in the early stages of a starburst episode. Contributions to the X-ray emission come from discrete point sources and extended diffuse emission, in the form of what appear to be multiple superbubbles, and smaller bubbles probably associated with individual star clusters. Chandra detects 17 sources within the optical extent of NGC5253 down to a completeness level corresponding to a luminosity of 1.5E37 erg/s.The slope of the point source X-ray luminosity function is -0.54, similar to that of other nearby dwarf starburst galaxies. Several different types of source are detected within the galaxy, including X-ray binaries and the emission associated with star-clusters. Comparison of the diffuse X-ray emission with the observed Halpha emission shows similarities in their extent. The best spectral fit to the diffuse emission is obtained with an absorbed, two temperature model giving temperatures for the two gas components of ~0.24keV and ~0.75keV.The derived parameters of the diffuse X-ray emitting gas are as follows: a total mass of \~1.4E6 f^{1/2} Msun, where f is the volume filling factor of the X-ray emitting gas, and a total thermal energy content for the hot X-ray emitting gas of \~3.4E54 f^{1/2} erg. The pressure in the diffuse gas is P/k ~ 1E6f^{-1/2}K/cm3. We find that these values are broadly commensurate with the mass and energy injection from the starburst population. Analysis of the kinematics of the starburst region suggest that the stellar ejecta contained within it can escape the gravitational potential well of the galaxy, and pollute the surrounding IGM.

description: Time to event data differ from other types of data because they are censored. Most of the related estimation techniques assume that the censoring mechanism is noninformative while in many applications it can actually be informative. The aim of this work is to introduce a class of flexible survival models which account for the information provided by the censoring times. The baseline functions are estimated non-parametrically by monotonic P-splines, whereas covariate effects are flexibly determined using additive predictors. Parameter estimation is reliably carried out within a penalized maximum likelihood framework with integrated automatic multiple smoothing parameter selection. We derive the n-consistency and asymptotic normality of the noninformative and informative estimators, and shed light on the efficiency gains produced by the newly introduced informative estimator when compared to its non-informative counterpart. The finite sample properties of the estimators are investigated via a Monte Carlo simulation study which highlights the good empirical performance of the proposal. The modeling framework is illustrated on data about infants hospitalized for pneumonia. The models and methods discussed in the article have been implemented in the R package GJRM to allow for transparent and reproducible research. Supplementary materials for this article are available online.
Evidence and Implications of Pressure Fluctuations in the ISM

Year: 2003
Subjects: subject: Astrophysics (astro-ph)

description: A recent survey of the fine-structure excitation of neutral carbon reveals that the interstellar medium in the Galactic plane exhibits a thermal pressure, nT/k, that ranges from about 10^3 to 10^4 cm{-3}K from one location to the next, with occasional excursions in excess of about 10^5 cm^{-3}K. The large excitations for small amounts of gas indicate that some regions are either subjected to shocks or must be pressurized within time scales much shorter than the time needed to reach thermal equilibrium. These rapid fluctuations probably arise from the cascade of macroscopic mechanical energy to small scales through a turbulent cascade. One consequence of this effect is that changes in gas temperature can arise from near adiabatic compressions and expansions, and this may explain why investigations of 21-cm emission and absorption reveal the presence of hydrogen at temperatures well below the expected values derived from the balance of various known heating and cooling processes.

description: IRAS F11119+3257 is a quasar-dominated Ultra-Luminous InfraRed Galaxy, with a partially obscured narrow-line seyfert 1 nucleus. In this paper, we present the NIR spectroscopy of F11119+3257, in which we find unusual Paschen emission lines, and metastable He I* $λ$10830 absorption associated with the previously reported atomic sodium and molecular OH mini-BAL (Broad Absorption Line) outflow. Photo-ionization diagnosis confirms previous findings that the outflows are at kilo-parsec scales. Such large-scale outflows should produce emission lines. We indeed find that high-ionization emission lines ([O III], [Ne III], and [Ne V]) are dominated by blueshifted components at similar speeds to the mini-BALs. The blueshifted components are also detected in some low-ionization emission lines, such as [O II] $λ$3727 and some Balmer lines (H$α$, H$β$, and H$γ$), even though their cores are dominated by narrow ($FWHM_{\rm NEL} = 570\pm40$km s$^{-1}$) or broad components at the systemic redshift of $z=0.18966\pm0.00006$. The mass flow rate (230-730$~M_\odot \rm yr^{-1}$) and the kinetic luminosity ($\dot{E}_k \sim 10^{43.6-44.8} $erg s$^{-1}$) are then inferred jointly from the blueshifted emission and absorption lines. In the NIR spectrum of F11119+3257, we also find that the Paschen emission lines are unique, in which a very narrow ($FWHM=260\pm20~$km s$^{-1}$) component is shown in only Pa$α$. This narrow component most probably comes from heavily obscured star formation. Based on the Pa$α$ and Pa$β$ emissions, we obtain an extinction at the $H$ band, $A_H~>~2.1$ (or a reddenning of $E_{B-V}~>~$3.7), and a star formation rate of $SFR~>~130\rm M_\odot yr^{-1}$ that resembles the estimates inferred from the FIR emissions ($SFR_{\rm FIR} = 190\pm90$ $M_\odot$ yr$^{-1}$).
