description: We investigate the time evolution and spatial variation of the stellar initial mass function (IMF) in star-forming disk galaxies by using chemodynamical simulations with an IMF model depending both on local densities and metallicities ([Fe/H]) of the interstellar medium (ISM). We find that the slope (alpha) of a power-law IMF (N(m) ~ m^-alpha) for stellar masses larger than 1M_sun evolves from the canonical Salpeter IMF (alpha ~ 2.35) to be moderately top-heavy one (alpha ~ 1.9) in the simulated disk galaxies with starbursts triggered by galaxy interaction. We also find that alpha in star-forming regions correlates with star formation rate densities (Sigma_SFR in units of M_sun yr^{-1} kpc^{-2}). Feedback effects of Type Ia and II supernovae are found to prevent IMFs from being too top-heavy (alpha < 1.5). The simulation predicts alpha ~ 0.23 log Sigma_SFR + 1.7 for log Sigma_SFR > -2 (i.e., more top-heavy in higher Sigma_SFR), which is reasonably consistent well with corresponding recent observational results. The present study also predicts that inner regions of starburst disk galaxies have smaller alpha thus are more top-heavy (d alpha/d R ~ 0.07 kpc^{-1} for R < 5 kpc). The predicted radial alpha gradient can be tested against future observational studies of the alpha variation in star-forming galaxies.

When to use the k-rule? Managing the risk of de-anonymisation in survey data
Creators: name: Perry, Anja
Publisher: name: Zenodo
Year: 2023
Subjects: data protection
anonymization
k-anonymity

description: Ethical and legal considerations require anonymisation to protect respondents’ privacy when sharing survey data. When anonymising data, it is often not sufficient to eliminate direct identifiers, such as names, contact details, and IP-addresses. Also indirect identifiers need to be considered. Indirect identifiers can, in combination, be used to re-identify respondents, for example, the ZIP code combined with an exceptionally high income. Here, social science survey data impose increased challenges on anonymization. The demographic information included are often very detailed and increase the re-identification risk.

 To manage this risk, social science data archives have processes in place to anonymize data or restrict data access. One strategy, k-anonymity, may help to protect respondents of certain surveys, but is not often discussed when anonymizing social science micro data. A dataset is k-anonymous “for k > 1 if, for each combination of key attributes, at least k records exist in the data set sharing that combination” (Domingo-Ferrer and Torra 2008, p. 991).

 Unique individuals in survey data are most often not considered problematic. Among other factors, sampling procedures make it nearly impossible to rule out that data twins may potentially exist in the population. In this contribution we look at conditions where the protection through sampling is violated or weak and we identify criteria that do make the application of k-anonymity necessary. Doing so, we analyse different risk components within a risk assessment framework for a survey where the exact sample can be replicated and a survey that can potentially include public figures. We compare the risk factors of both survey with a large population survey in which protection through sampling is present.

description: The branching ratios of K^- absorption at rest in nuclear matter are evaluated from the K^- self-energy by using the chiral unitary approach for the s-wave \bar{K} N amplitude. We find that both the mesonic and non-mesonic absorption potentials are dominated by the Λ(1405) contributions. We also observe that the mesonic absorption ratio [π^{-} Σ^{+}] / [π^{+} Σ^{-}] increases as a function of nuclear density due to the interference between Λ(1405) and the I=1 non-resonant background, which is consistent with experimental results. The fraction of the non-mesonic absorption is evaluated to be about 30 % at the saturation density. The branching ratios of the K^- absorption at rest into deuteron and 4He are also calculated.

description: We present studies of an effective model which is a simple generalization of the standard model of a local pair superconductor with on-site pairing (i.e., the model of hard core bosons on a lattice) to the case of finite pair binding energy. The tight binding Hamiltonian consists of (i) the effective on-site interaction U, (ii) the intersite density-density interactions W between nearest-neighbours, and (iii) the intersite charge exchange term I, determining the hopping of electron pairs between nearest-neighbour sites. In the analysis of the phase diagrams and thermodynamic properties of this model we treat the intersite interactions within the mean-field approximation. Our investigations of the U<0 and W>0 case show that, depending on the values of interaction parameters, the system can exhibit three homogeneous phases: superconducting (SS), charge-ordered (CO) and nonordered (NO) as well as the phase separated SS-CO state.

description: In this research we aim to investigate the job shop scheduling problem with uncertain processing times. First we study the literature for the best solution approaches for the deterministic job shop problem. Among all developed algorithms in the literature the famous TSAB algorithm by Nowicki and Smutnicki in 1996 has shown well performance regarding the quality of solutions and CPU time. Then we develop and solve a two stage stochastic programming model, using TSAB and Sample Average Approximation technique, assuming the data are uncertain and associated with a well-known distribution. Furthermore, for more complex uncertainties we study robust and distributionally robust optimization techniques.

description: In this work we investigate in detail the effects local environment (groups and pairs) has on galaxies with stellar mass similar to the Milky-Way (L* galaxies). A volume limited sample of 6,150 galaxies is classified to determine emission features, morphological type and presence of a disk. This sample allows for characteristics of galaxies to be isolated (e.g. stellar mass and group halo mass), and their codependencies determined. We observe that galaxy-galaxy interactions play the most important role in shaping the evolution within a group halo, the main role of halo mass is in gathering the galaxies together to encourage such interactions. Dominant pair galaxies find their overall star formation enhanced when the pair's mass ratio is close to 1, otherwise we observe the same galaxies as we would in an unpaired system. The minor galaxy in a pair is greatly affected by its companion galaxy, and whilst the star forming fraction is always suppressed relative to equivalent stellar mass unpaired galaxies, it becomes lower still when the mass ratio of a pair system increases. We find that, in general, the close galaxy-galaxy interaction rate drops as a function of halo mass for a given amount of stellar mass. We find evidence of a local peak of interactions for Milky-Way stellar mass galaxies in Milky-Way halo mass groups. Low mass halos, and in particular Local Group mass halos, are an important environment for understanding the typical evolutionary path of a unit of stellar mass. We find compelling evidence for galaxy conformity in both groups and pairs, where morphological type conformity is dominant in groups, and emission class conformity is dominant in pairs. This suggests that group scale conformity is the result of many galaxy encounters over an extended period of time, whilst pair conformity is a fairly instantaneous response to a transitory interaction.

description: Suppose P is a set of primes, such that for every p in P, every prime factor of p-1 is also in P. If P does not contain all primes, we apply a new sieve method to show that the counting function of P is O(x^{1-c}) for some c>0, where c depends only on the smallest prime not in P. Our proof makes use of results connected with Artin's primitive root conjecture.

Semileptonic Decays of Pseudoscalar Mesons: A New Approach
Creators: name: Chia, Swee Ping
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Because quarks in hadronic states are subjected to strong QCD forces, it is not straight-forward to apply calculation obtained at the quark level to physical processes involving hadrons. In this paper we present a new approach to treat the semileptonic decays of pseudoscalar mesons. At the quark level, the process is straightforward. However, when we fold the quark-level process to the meson decay process, the complication from QCD effects come in. We make the fundamental assumption that the vertex of type M-q-qbar can be approximated by an effective constant gamma-5 coupling. With this assumption, the hadronic process can then be related to the quark-level process. The model is applied to the semileptonic decays of pi, K, D and B mesons.
Developing a New Hybrid Kinetic Model for Chemical Recycling of Vinyl Polymers

description: Continuously increasing amounts of solid plastic waste (SPW) are being generated worldwide. Chemical recycling techniques, e.g. pyrolysis, show a great potential to reduce the environmental harm induced by SPW pollution. These techniques can be combined with innovative chemical processes driven by renewable energy, resulting in carbon circularity. Detailed kinetic modeling is required to understand and optimize these processes. The main aim of this work is to develop a detailed kinetic model for the thermal pyrolysis of vinyl polymers. The model combines a detailed explicit simulation of the chemistry of the light species with the Method of Moments to simulate heavy species. The model contains 9 reaction families, 45 species, and 66 moments. The explicit simulation and MoM are linked via a dedicated routine, based on the gamma distribution. The model simulations are performed with a new computational framework that implements an evaporation model, the exact simulation of the light species, the MoM-based simulation of the heavy species, and the links between these modeling regimes. The constructed preliminary model is validated against detailed pyrolysis product distributions. The preliminary model results yield a proof of concept for this new modeling approach.

description: The transient neutron star low-mass X-ray binary and 11 Hz X-ray pulsar IGR J17480-2446 in the globular cluster Terzan 5 exhibited an 11-week accretion outburst in 2010. Chandra observations performed within five months after the end of the outburst revealed evidence that the crust of the neutron star became substantially heated during the accretion episode and was subsequently cooling in quiescence. This provides the rare opportunity to probe the structure and composition of the crust. Here, we report on new Chandra observations of Terzan 5 that extend the monitoring to ~2.2 yr into quiescence. We find that the thermal flux and neutron star temperature have continued to decrease, but remain significantly above the values that were measured before the 2010 accretion phase. This suggests that the crust has not thermally relaxed yet, and may continue to cool. Such behavior is difficult to explain within our current understanding of heating and cooling of transiently accreting neutron stars. Alternatively, the quiescent emission may have settled at a higher observed equilibrium level (for the same interior temperature), in which case the neutron star crust may have fully cooled.

description: The Iapetus -1:0 nodal bending wave, the first spiral wave ever described in Saturn's rings, has been seen again for the first time in 29 years. We demonstrate that it is in fact the nodal bending wave, not the 1:0 apsidal density wave as previously reported. We use wavelet analysis to determine the wavelength profile, thus deriving the surface density at every point in the region covered by the bending wave. This profile is consistent with surface densities measured from more localized spiral density waves in the outer Cassini Division and the inner and mid-A Ring, varying smoothly from the low values of the former to the higher values of the latter. Most remarkably, our analysis indicates that there is no significant change in surface density across the boundary between the outer Cassini Division and the inner-A ring, despite the very abrupt increase in optical depth and reflected brightness at this location. We consider anew the nature of the classically identified "inner edge of the A ring," given that it does not appear to be correlated with any abrupt increase in surface density. There is an abrupt increase in surface density at the Pandora 5:4 density wave, ~300 km outward of the A ring's inner edge. Further study is needed to robustly interpret our findings in terms of particle properties and abundances, much less to explain the origins of the implied structure.

description: Using a corpus of 17,000+ financial news reports (involving over 10M words), we perform an analysis of the argument-distributions of the UP and DOWN verbs used to describe movements of indices, stocks and shares. In Study 1 participants identified antonyms of these verbs in a free-response task and a matching task from which the most commonly identified antonyms were compiled. In Study 2, we determined whether the argument-distributions for the verbs in these antonym-pairs were sufficiently similar to predict the most frequently-identified antonym. Cosine similarity correlates moderately with the proportions of antonym-pairs identified by people (r = 0.31). More impressively, 87% of the time the most frequently-identified antonym is either the first- or second-most similar pair in the set of alternatives. The implications of these results for distributional approaches to determining metaphoric knowledge are discussed.

description: As video games experience a rise in popularity, the issues of participating in this hobby become more concerning. For mental health, problems with video games can lead to an exacerbating effect on psychiatric disorders such as anxiety and depression. This thesis gathers sources from across psychology and communication disciplines to determine the effects of video games on the mental health of adolescents and college students. This literature review finds that the effects of video games on the mental health of adolescents and college students are complex. I examined and compared the results of various studies over the last 20 years and offer conclusions and propose solutions to these issues. Using the existing literature, I show that playing video games obsessively can be an issue. However, in the absence of addiction, video games can be used to treat symptoms or aid therapists for mental health issues as they relate to psychiatric disorders. Simply playing video games will generally not affect college students or adolescents negatively. When paired with addiction or obsession, however, video games are correlated with the development of psychiatric disorders. But addiction and obsession are not defined by the amount of time that video games are played. In the case of depression, playing video games through an addiction or obsessively can worsen symptoms or correlate with their development. Some studies show anxiety can be correlated to video game addiction, and others show the opposite result. There is little research in this field of study, and as such, more studies and experiments should investigate this phenomenon. Specifically, research should be done to determine if video game addiction, usage, and psychiatric disorders are correlated and whether video games can be used by health professionals to combat these disorders.

description: Graphene has vast promising applications on the nanoelectronics and spintronics because of its unique magnetic and electronic properties. Making use of an ab initio spin-polarized density functional theory, implemented by the method of Heyd-Scuseria-Ernzerhof 06(HSE06) hybrid functional, the properties of nitrogen substitutional dopants in semi-metal monolayer graphene were investigated. We found from our calculation, that introducing nitrogen doping would possibly break energy degeneracy with respect to spin(spin symmetry breaking) at some doping concentrations with proper dopant configurations. The spin symmetry breaking would cause spin-polarized effects, which induce magnetic response in graphene. This paper systematically analyzed the dependence of magnetic moments and band gaps in graphene on doping concentrations of nitrogen atoms, as well as dopant configurations.

description: Spectral algorithms are classic approaches to clustering and community detection in networks. However, for sparse networks the standard versions of these algorithms are suboptimal, in some cases completely failing to detect communities even when other algorithms such as belief propagation can do so. Here we introduce a new class of spectral algorithms based on a non-backtracking walk on the directed edges of the graph. The spectrum of this operator is much better-behaved than that of the adjacency matrix or other commonly used matrices, maintaining a strong separation between the bulk eigenvalues and the eigenvalues relevant to community structure even in the sparse case. We show that our algorithm is optimal for graphs generated by the stochastic block model, detecting communities all the way down to the theoretical limit. We also show the spectrum of the non-backtracking operator for some real-world networks, illustrating its advantages over traditional spectral clustering.

description: In engineering systems with extreme environmental conditions, proper sealing of machine components is especially important, e.g. in the space industry.
 The effectiveness of the seal depends largely on the method of sealing and the materials used. The investigation aims to research the abrasion phenomena of moving machine elements of the rotary shaft/seal relationship that is subjected to dry friction and intense abrasion in Martian and Lunar environments.
 The main objective is to determine the wear sensitivity of the rotating shaft/sealing units by performing laboratory tests both on a simplified coupon level and in a more complex real shaft/seal connection test. These enable material ranking and aid further material selection for the application.

description: We describe observed properties of the Type Iax class of supernovae (SNe Iax), consisting of SNe observationally similar to its prototypical member, SN 2002cx. The class currently has 25 members, and we present optical photometry and/or optical spectroscopy for most of them. SNe Iax are spectroscopically similar to SNe Ia, but have lower maximum-light velocities (2000 < |v| < 8000 km/s), typically lower peak magnitudes (-14.2 > M_V,peak > -18.9 mag), and most have hot photospheres. Relative to SNe Ia, SNe Iax have low luminosities for their light-curve shape. There is a correlation between luminosity and light-curve shape, similar to that of SNe Ia, but offset from that of SNe Ia and with larger scatter. Despite a host-galaxy morphology distribution that is highly skewed to late-type galaxies without any SNe Iax discovered in elliptical galaxies, there are several indications that the progenitor stars are white dwarfs (WDs): evidence of C/O burning in their maximum-light spectra, low ejecta masses, strong Fe lines in their late-time spectra, a lack of X-ray detections, and deep limits on massive stars and star formation at the SN sites. However, two SNe Iax show strong He lines in their spectra. The progenitor system and explosion model that best fits all of the data is a binary system of a C/O WD that accretes matter from a He star and has a significant deflagration. At least some of the time, this explosion will not disrupt the WD. We estimate that in a given volume there are 31^+17_-13 SNe Iax for every 100 SNe Ia, and for every 1 M_sun of iron generated by SNe Ia at z = 0, SNe Iax generate 0.052^+0.017_-0.014 M_sun. Being the largest class of peculiar SNe, thousands of SNe Iax will be discovered by LSST. Future detailed observations of SNe Iax should further our understanding of both their progenitor systems and explosions as well as those of SNe Ia.

These distances make use of the unique combination of depth and spatial coverage of the Pan-Andromeda Archaeological Survey (PAndAS) to provide a large, homogeneous sample consisting of 27 of M31's satellites, as well as M31 itself. We find that the satellite distribution, when viewed as a whole, is no more planar than one would expect from a random distribution of equal size. A disk consisting of 15 of the satellites is however found to be highly significant, and strikingly thin, with a root-mean-square thickness of just $12.34^{+0.75}_{-0.43}$ kpc. This disk is oriented approximately edge on with respect to the Milky Way and almost perpendicular to the Milky Way disk. It is also roughly orthogonal to the disk like structure regularly reported for the Milky Way satellite system and in close alignment with M31's Giant Stellar Stream. A similar analysis of the asymmetry of the M31 satellite distribution finds that it is also significantly larger than one would expect from a random distribution. In particular, it is remarkable that 20 of the 27 satellites most likely lie on the Milky Way side of the galaxy, with the asymmetry being most pronounced within the satellite subset forming the aforementioned disk. This lopsidedness is all the more intriguing in light of the apparent orthogonality observed between the satellite disk structures of the Milky Way and M31.

description: We developed a time-correlated single-photon counting (TCSPC) system based on the low-jitter superconducting nanowire single-photon detection (SNSPD) technology. The causes of jitters in the TCSPC system were analyzed. Owing to the low jitter of the SNSPD technology, a system jitter of 26.8 ps full-width at half-maximum was achieved after optimizing the system. We demonstrated time-of-flight laser ranging at 1550 nm wavelength at a stand-off distance of 115 m, based on this TCSPC system. A depth resolution of 4 mm was achieved directly by locating the centroids of each of the two return signals. Laser imaging was also performed using the TCSPC system. This low-jitter TCSPC system using the SNSPD technology presents great potential in long-range measurements and imaging applications for low-energy-level and eye-safe laser systems

Large N Phase Transitions, Finite Volume, and Entanglement Entropy
Creators: name: Johnson, Clifford V.
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Holographic studies of the entanglement entropy of field theories dual to charged and neutral black holes in asymptotically global AdS4 spacetimes are presented. The goal is to elucidate various properties of the quantity that are peculiar to working in finite volume, and to gain access to the behaviour of the entanglement entropy in the rich thermodynamic phase structure that is present at finite volume and large N. The entropy is followed through various first order phase transitions, and also a novel second order phase transition. Properties of a specific heat in the neighbourhood of the critical point are computed. Behaviour is found that contrasts interestingly with an earlier holographic study of a second order phase transition dual to an holographic superconductor.

description: The crime scene examination is conducted to assist with investigating a criminal incident and to identify the perpetrator(s) involved. Over the last few years, the field of forensics has made dramatic scientific advancements in DNA methodologies, analyses of methods of evidence, and the complexity of related databases. It has generally been proposed that the most dependable method for distinguishing crimes carried out by a specific offender is by comprehensively collecting and analyzing physical evidence at the crime scene (Grubin, Kelly & Brunsdon, 2001). One rather effective option has been DNA profiling. This is accomplished by carefully recording the conditions at a crime location and identifying all pertinent physical evidence. Once completed, DNA samples can be collected and subsequently analyzed in an approved crime lab. It is obvious that the capacity to uncover and appropriately gather physical evidence is vital to solving and investigating violent and serious crimes. On the other hand, in many criminal incidents, little or no physical evidence exists or is often not collected.

description: A new concept of the available force in long-range interaction complex systems is proposed. The relationship between the available force in different time intervals and the interaction parameters of complex systems is described. It is found that when the interaction parameters satisfy a determined condition, the trajectory that the velocity is divergent but the displacement is convergent can be well described and that the long-range interaction, anomalous diffusion, and q-Gaussian type distribution of complex systems can also be well described by the interaction parameters in different cases. In addition, by utilizing the velocity of time series randomly and analyzing its probability distribution of displacement, it is explained that when there exists the long-range interaction in complex systems, the fat-tail distributions will exhibit. The results obtained show that the relationship between the available force and the interaction parameters may be used to investigate the statistical physical properties in long-range interaction complex systems.

Computational ghost imaging versus imaging laser radar for 3D imaging

description: Ghost imaging has been receiving increasing interest for possible use as a remote-sensing system. There has been little comparison, however, between ghost imaging and the imaging laser radars with which it would be competing. Toward that end, this paper presents a performance comparison between a pulsed, computational ghost imager and a pulsed, floodlight-illumination imaging laser radar. Both are considered for range-resolving (3D) imaging of a collection of rough-surfaced objects at standoff ranges in the presence of atmospheric turbulence. Their spatial resolutions and signal-to-noise ratios are evaluated as functions of the system parameters, and these results are used to assess each system's performance trade-offs. Scenarios in which a reflective ghost-imaging system has advantages over a laser radar are identified.

Decay Constants of Pseudoscalar Mesons
Creators: name: Chia, Swee Ping
Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: For purely leptonic decays of pseudoscalar mesons, the decay rates are related to the product of the relevant weak interaction-based CKM matrix element of the constituent quarks on the one hand, and the strong interaction parameter, the decay constant, which is related to the overlap of the quark and antiquark in the meson on the other hand. The decay constants for these mesons can thus be estimated from the decay rates of the respective dominant decay modes. The decay constants so obtained are used to estimate the decay rates of the less dominant modes, which are in good agreement with experimentally measured values. We also predict the decay rates for tau-lepton.
On some type of Hardy's inequality involving generalized power means

description: We discuss properties of certain generalization of Power Means proposed in 1971 by Carlson, Meany and Nelson. For any fixed parameter (k,s,q) and vector (v_1,...,v_n) they take the q-th power means of all possible k-tuples (v_{i_1},...,v_{i_k}), and then calculate the s-th power mean of the resulting vector of length C_n^k. We work towards a complete answer to the question when such means satisfy inequalities resembling the classical Hardy inequality. We give a definitive answer in a large part of the parameter space. An unexpected corollary is that this family behaves much differently than most of other families admitting Hardy-type inequalities. Namely, arbitrarily small perturbations of parameters may lead to the breakdown of such inequalities.

Spectral density of a Wishart model for nonsymmetric Correlation Matrices
Creators: name: Vinayak
Publisher: name: arXiv
Year: 2013
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: The Wishart model for real symmetric correlation matrices is defined as $\mathsf{W}=\mathsf{AA}^{t}$, where matrix $\mathsf{A}$ is usually a rectangular Gaussian random matrix and $\mathsf{A}^{t}$ is the transpose of $\mathsf{A}$. Analogously, for nonsymmetric correlation matrices, a model may be defined for two statistically equivalent but different matrices $\mathsf{A}$ and $\mathsf{B}$ as $\mathsf{AB}^{t}$. The corresponding Wishart model, thus, is defined as $\mathbf{C}=\mathsf{AB}^{t}\mathsf{BA}^{t}$. We study the spectral density of $\mathbf{C}$ for the case when $\mathsf{A}$ and $\mathsf{B}$ are not statistically independent. The ensemble average of such nonsymmetric matrices, therefore, does not simply vanishes to a null matrix. In this paper we derive a Pastur self-consistent equation which describes spectral density of large $\mathbf{C}$. We complement our analytic results with numerics.
