description: An Ising model with ferromagnetic nearest-neighbor interactions $J_{1}$ ($J_{1}>0$) and random next-nearest-neighbor interactions [$+J_{2}$ with probability $p$ and $-J_{2}$ with probability $(1-p)$; $J_{2}>0$] is studied within the framework of an effective-field theory based on the differential-operator technique. The order parameters are calculated, considering finite clusters with $n=1,2, {\rm and} 4$ spins, using the standard approximation of neglecting correlations. A phase diagram is obtained in the plane temperature versus $p$, for the particular case $J_{1}=J_{2}$, showing both superantiferromagnetic (low $p$) and ferromagnetic (higher values of $p$) orderings at low temperatures.

description: A new clustering accuracy measure is proposed to determine the unknown number of clusters and to assess the quality of clustering of a data set given in any dimensional space. Our validity index applies the classical nonparametric univariate kernel density estimation method to the interpoint distances computed between the members of data. Being based on interpoint distances, it is free of the curse of dimensionality and therefore efficiently computable for high-dimensional situations where the number of study variables can be larger than the sample size. The proposed measure is compatible with any clustering algorithm and with every kind of data set where the interpoint distance measure can be defined to have a density function. Simulation study proves its superiority over widely used cluster validity indices like the average silhouette width and the Dunn index, whereas its applicability is shown with respect to a high-dimensional Biostatistical study of Alon data set and a large Astrostatistical application of time series with light curves of new variable stars.

description: We consider Dirichlet-to-Neumann maps associated with (not necessarily self-adjoint) Schrodinger operators describing nonlocal interactions in $L^2(Ω; d^n x)$, $n\geq 2$, where $Ω$ is an open set with a compact, nonempty boundary satisfying certain regularity conditions. As an application we describe a reduction of a certain ratio of Fredholm perturbation determinants associated with operators in $L^2(Ω; d^n x)$ to Fredholm perturbation determinants associated with operators in $L^2(\partialΩ; d^{n-1}σ)$. This leads to an extension of a variant of a celebrated formula due to Jost and Pais, which reduces the Fredholm perturbation determinant associated with a Schrödinger operator on the half-line $(0,\infty)$, in the case of local interactions, to a Wronski determinant of appropriate distributional solutions of the underlying Schrodinger equation.

description: A comparative study of optical spectra of Type Ia supernovae (SNe Ia) is extended, in the light of new data. The discussion is framed in terms of the four groups defined in previous papers of this series: core normal (CN); broad line (BL); cool (CL); and shallow silicon (SS). Emerging features of the SN Ia spectroscopic diversity include evidence (1) that extreme CL SN 1991bg-likes are not a physically distinct subgroup and (2) for the existence of a substantial number of SN 1999aa-like SSs that are very similar to each other and distinguishable from CN even as late as three weeks after maximum light. SN 1999aa-likes may be relatively numerous, yet not a physically distinct subgroup. The efficacy of quantitative spectroscopic subclassification of SNe Ia based on the equivalent widths of absorption features near 5750 A and 6100 A near maximum light is discussed. The absolute magnitude dispersion of a small sample of CNs is no larger than the characteristic absolute magnitude uncertainty.

Predicting the performance of a nuclear power plant pressurizer
Creators: name: Yaremy, Eugene Miron
Publisher: name: University of British Columbia
Year: 2012

description: Up to this time, the design of Pressurizers in Nuclear Power Plants has been quite empirical due to the deficiency of standard thermodynamic relationships when applied to the solution of two phase systems. Recently, a new thermodynamic approach was expounded to the 2nd Nuclear Engineering and Science Conference which attempts to deal with the problem of two phase systems by breaking the thermodynamic unit into various subsystems and solving each separately. However, no experimental proof of the new theory was given. The object of this investigation was to prove or disprove the validity of this new thermodynamic approach as applied to the prediction of the performance of a Pressurizer. A small, simplified model of a pressurizer was constructed, and surge tests were conducted. The surges were then calculated by means of the new thermodynamic equations and compared with the actual results. It was found that the prediction of pressurizer surges depends greatly upon the exactness to which the transient heat loss to the walls of the pressurizer can be calculated. Nevertheless, the use of standard heat transfer relationships when used in the theoretical surge equations, predicted the pressure surges to within 40%. An attempt to obtain closer theoretical results by determining the transient heat loss from pressure and temperature decay curves was unsuccessful due to improper pressure recording equipment. Some doubt has been cast on one of the assumptions of the theoretical equations, in that the pressurizer steam was not compressed isentropically as assumed. It is felt that this deviation from the theoretical was due to the small size of the model pressurizer, but proof of this is left to future experimenters. This investigation did prove that with this new thermodynamic approach of subsystems, and with the use of standard heat transfer expressions, the performance of nuclear power plant pressurizers can be predicted within reasonable limits.

description: Using density matrix equations of motion, we predict a femtosecond collective spin tilt triggered by nonlinear, near--ultraviolet ($\sim$3eV), coherent photoexcitation of (Ga,Mn)As ferromagnetic semiconductors with linearly polarized light. This dynamics results from carrier coherences and nonthermal populations excited in the \{111\} equivalent directions of the Brillouin zone and triggers a subsequent uniform precession. We predict nonthermal magnetization control by tuning the laser frequency and polarization direction. Our mechanism explains recent ultrafast pump--probe experiments.

To construct the solution we use localization method. We also apply these results to get the existence of an optimal control strategy for the mixed stochastic control problem in finite horizon.

Moving Finite Size Particles in a Flow: A Physical Example for Pitchfork Bifurcations of Tori

Subjects: subject: Chaotic Dynamics (nlin.CD)

description: The motion of small, spherical particles of finite size in fluid flows at low Reynolds numbers is described by the strongly nonlinear Maxey-Riley equations. Due to the Stokes drag the particle motion is dissipative, giving rise to the possibility of attractors in phase space. We investigate the case of an infinite, cellular flow field with time-periodic forcing. The dynamics of this system are studied in a part of the parameter space. We focus particularly on the size of the particles whose variations are most important in active, physical processes, for example for aggregation and fragmentation of particles. Depending on their size the particles will settle on different attractors in phase space in the long term limit, corresponding to periodic, quasiperiodic or chaotic motion. One of the invariant sets that can be observed in a large part of this parameter region is a quasiperiodic motion in form of a torus. We identify some of the bifurcations that these tori undergo, as particle size and mass ratio relative to the fluid are varied. This way we provide a physical example for sub- and supercritical pitchfork bifurcations of tori.

description: Hot atmospheres pervading galaxy clusters, groups, and early-type galaxies are rich in metals, produced during epochs and diffused via processes that are still to be determined. While this enrichment has been routinely investigated in clusters, metals in lower mass systems are more challenging to probe with standard X-ray exposures and spectroscopy. In this paper, we focus on very deep XMM-Newton ($\sim$350 ks) observations of NGC 1404, a massive elliptical galaxy experiencing ram-pressure stripping of its hot atmosphere while infalling toward the centre of the Fornax cluster, with the aim to derive abundances through its hot gas extent. Importantly, we report the existence of a new fitting bias - the "double Fe bias" - leading to an underestimate of the Fe abundance when two thermal components cannot realistically model the complex temperature structure present in the outer atmosphere of the galaxy. Contrasting with the ''metal conundrum'' seen in clusters, the Fe and Mg masses of NGC 1404 are measured 1-2 orders of magnitude below what stars and supernovae could have reasonably produced and released. In addition, we note the remarkable Solar abundance ratios of the galaxy's halo, different from its stellar counterpart but similar to the chemical composition of the ICM of rich clusters. Completing the clusters regime, all these findings provide additional support toward a scenario of early enrichment, at play over two orders of magnitude in mass. A few peculiar and intriguing features, such as a possible double metal peak as well as an apparent ring of enhanced Si near the galaxy core, are also discussed.

description: The cosmological many-body problem is effectively an infinite system of gravitationally interacting masses in an expanding universe. Despite the interactions' long-range nature, an analytical theory of statistical mechanics describes the spatial and velocity distribution functions which arise in the quasi-equilibrium conditions that apply to many cosmologies. Consequences of this theory agree well with the observed distribution of galaxies. Further consequences such as thermodynamics provide insights into the physical properties of this system, including its robustness to mergers, and its transition from a grand canonical ensemble to a collection of microcanonical ensembles with negative specific heat.

Measurements are performed with the MASS (Multi-Aperture Scintillation Sensor) device which is widely used in similar studies during last years at several observatories across the world. The data analysis shows that median seeing in free atmosphere (at altitudes above 0.5km) is 0.46 arcsec and median isoplanatic angle is 2.47 arcsec. Given a rather long atmospheric coherence time (about 7 ms when the seeing is good) such conditions are favorable for adaptive optics and interferometry in the visible and near-IR.

description: Passive intermodulation (PIM) is a niggling phenomenon that debilitates performance of modern communications and navigation systems. PIM products interfere with the information signals and cause their nonlinear distortion. The sources and basic mechanisms of PIM were studied in literature but PIM remains a serious problem of signal integrity. In this paper, the main sources and mechanisms of PIM generation by joints of good conductors are discussed. It is shown that the passive electrical, thermal and mechanical nonlinearities are intrinsically linked despite their distinctively different time scales. The roughness of the contact surfaces plays an important role in PIM generation by conductor joints. A review of the PIM phenomenology at contacts of the good conductors suggests that novel multiphysics models are necessary for the analysis and reliable prediction of PIM products generated by several concurrent nonlinearities of diverse physical nature.

description: In this work, we explore the relevant methodology for the investigation of interacting systems with contact interactions, and we introduce a class of zonal estimators for path-integral Monte Carlo methods, designed to provide physical information about limited regions of inhomogeneous systems.We demonstrate the usefulness of zonal estimators by their application to a system of trapped bosons in a quasiperiodic potential in two dimensions, focusing on finite temperature properties across a wide range of values of the potential. Finally, we comment on the generalization of such estimators to local fluctuations of the particle numbers and to magnetic ordering in multi-component systems, spin systems, and systems with nonlocal interactions.

A novel and precise time domain description of MOSFET low frequency noise due to random telegraph signals

description: Nowadays, random telegraph signals play an important role in integrated circuit performance variability, leading for instance to failures in memory circuits. This problem is related to the successive captures and emissions of electrons at the many traps stochastically distributed at the silicon-oxide (Si-SiO2) interface of MOS transistors. In this paper we propose a novel analytical and numerical approach to statistically describe the fluctuations of current due to random telegraph signal in time domain. Our results include two distinct situations: when the density of interface trap density is uniform in energy, and when it is an u-shape curve as prescribed in literature, here described as simple quadratic function. We establish formulas for relative error as function of the parameters related to capture and emission probabilities. For a complete analysis experimental u-shape curves are used and compared with the theoretical aproach.
Deformable One-Dimensional Object Detection for Routing and Manipulation

description: Many methods exist to model and track deformable one-dimensional objects (e.g., cables, ropes, and threads) across a stream of video frames. However, these methods depend on the existence of some initial conditions. To the best of our knowledge, the topic of detection methods that can extract those initial conditions in non-trivial situations has hardly been addressed. The lack of detection methods limits the use of the tracking methods in real-world applications and is a bottleneck for fully autonomous applications that work with these objects. This paper proposes an approach for detecting deformable one-dimensional objects which can handle crossings and occlusions. It can be used for tasks such as routing and manipulation and automatically provides the initialization required by the tracking methods. Our algorithm takes an image containing a deformable object and outputs a chain of fixed-length cylindrical segments connected with passive spherical joints. The chain follows the natural behavior of the deformable object and fills the gaps and occlusions in the original image. Our tests and experiments have shown that the method can correctly detect deformable one-dimensional objects in various complex conditions.

description: Using a dataset of more than 90,000 metal music reviews written by over 9,000 users in a period of 15 years, we analyse the genre structure of metal music with the aid of review text information. We model the relationships between genres using a user-oriented network, based on the written reviews. We then perform community detection and employ a network "averaging" method to obtain stable genre clusters, in order to analyse the structures of clusters both locally within each cluster and globally over the entire network. In addition to identifying the clusters, we use Dependency Parsing and modified Term Frequency - Inverse Document Frequency to extract significant and unique features of each cluster. These structures and review text information can allow us to understand how music audience (fans) perceive similar and different genres, and also assist in classifying different genres which share common-interest user communities, offering a more objective way in grouping music genres. Furthermore, the classification can also help recommendation engines provide more targeted suggestions of music, and potentially help musicians to select genre labels for their music, and design music to better cater to preferences of their audiences based on previous reviews.

Verstraete, Phys. Rev. Lett. {\bf 96}, 220503 (2006)] hold on general $n$-qubit states including mixed ones. In this paper, we consider the monogamy inequalities in terms of the fully entangled fraction and the teleportation fidelity. We show that the monogamy inequalities do not hold on general mixed states, while the inequalities hold on $n$-qubit pure states.

description: Juvenile sockeye, coho, and chum salmon and adult goldfish were studied for a period of ten weeks to determine whether varying degrees of salinity influenced their growth. The possible influences of such factors as temperature and food were rigidly controlled. Coho and chum salmon showed higher percent weight increase in the saline media. Coho grew best in 12% salinity and chum had a higher percent increase in weight in 30% salinity. The growth of sockeye in the saline medium was retarded for the first eight weeks, but during the last two weeks it surpassed that of the corresponding group of sockeye in fresh water. The early retardation in growth of sockeye, in the saline medium, is attributed to its longer fresh water life. The adult goldfish did not show any significant difference in weight increase. The records of the sizes attained by several species of fish inhabiting both sea and fresh waters show that salinity enhances growth. The evidence from experimental study, by other workers, on the influence of different environmental factors on growth of fishes, indicates that changes in meristic counts or body proportions, in early development, produces different growth rates. These changes could eventually affect the ultimate size. The physiological mechanisms of growth of fishes are not well understood, but it has been suggested that the influence of hormones on growth is probably ameliorated in the marine environment.

description: Dust explosion occurs when ignition energy is given to a flammable particle clouds dispersed in air.
During dust explosion, high speed flame propagation occurs and pressure rises significantly. Since the
specific surface area increases as the particle size decreases, the risk of dust explosion increases.
However, when the particle size is further decreases to several tens micro meters, agglomeration occurs
easily, and dispersion condition changes. In order to appropriately evaluate the risk of dust explosion of
fine particles, it is necessary to study the relationship between flame propagation behavior and particle
characteristics, such as size and agglomeration. The purpose of this study is to investigate the effects of
particle size and agglomeration on flame propagation behavior in dust clouds. The flame propagation
behavior was examined changing the particle size of PMMA particles and the effect of particle
agglomeration was investigated. On this account, PMMA particles with a very narrow particle size
distribution were used. As a result, the minimum explosible concentration increased as the particle size
decreased. On the other hand, the flame propagation velocity increased as the particle size decreased. In
this way, the minimum explosible concentration and flame propagation velocity showed the opposite
tendency to the particle size. It is considered that the inter-particle distance will be important for the
minimum explosible concentration, meanwhile the specific surface area will be important for the flame
propagation velocity. The severity of the explosion can be serious for the smaller particles, despite the
minimum explosible concentration is large and the occurrence probability is low.

E' noto che l'impatto avvenuto 66 milioni di anni fa in Messico ha provocato la grande estinzione del Cretaceo-Terziario, ma in contemporanea potrebbe aver innescato le massicce eruzioni di lava del Deccan, in India. Gli eventi sembrano collegati e sempre più ricercatori ne sono convinti
Dynamics of Intermediate-Mass Black Holes Wandering in the Milky Way Galaxy Using the Illustris TNG50 Simulation

description: The detection of Intermediate-Mass Black Holes (IMBHs) in dwarf galaxies is crucial to closing the gap in the wide mass distribution of black holes ($\sim 3 \, \rm M_{\odot}$ to $\sim 5 \times 10^{10} \, \rm M_{\odot}$). IMBHs originally located at the center of dwarfs that later collide with the Milky Way (MW) could be wandering, undetected, in our Galaxy. We used TNG50, the highest-resolution run of the IllustrisTNG project, to study the kinematics and dynamics of star clusters, in the appropriate mass range, acting as IMBH proxies in a MW analog galaxy. We showed that $\sim 87\%$ of our studied IMBHs drift inward. The radial velocity of these sinking IMBHs has a median magnitude of $\sim 0.44 \, \rm ckpc \, h^{-1} \, Gyr^{-1}$ and no dependence on the black hole mass. The central $1 \, \rm ckpc \, h^{-1}$ has the highest number density of IMBHs in the galaxy. A physical toy model with linear drag forces was developed to explain the orbital circularization with time. These findings constrain the spatial distribution of IMBHs, suggesting that future searches should focus on the central regions of the Galaxy. Additionally, we found that the 3D velocity distribution of IMBHs with respect to the galactic center has a mean of $\sim 180 \, \rm km \, s^{-1}$ and larger variance with decreasing radius. Remarkably, the velocity distribution relative to the local gas shows significantly lower values, with a mean of $\sim 88 \, \rm km \, s^{-1}$. These results are instrumental for predicting the accretion and radiation properties of IMBHs, facilitating their detection with future surveys.
