description: We estimate actuarially sound premium rates for individual yield guarantee and income protection crop insurance products for Georgia and South Carolina peaches. In most cases, the premium rate for an income protection product equals or exceeds the premium rate for an individual yield guarantee product for a given coverage level and average farm yield. Although the premium rates for the two products differ in a statistical sense, they do not appear to differ in an economic sense except at high coverage levels for growers with very high yields.

description: This paper presents a crowd monitoring system based on the passive detection of probe requests. The system meets strict privacy requirements and is suited to monitoring events or buildings with a least a few hundreds of attendees. We present our counting process and an associated mathematical model. From this model, we derive a concentration inequality that highlights the accuracy of our crowd count estimator. Then, we describe our system. We present and discuss our sensor hardware, our computing system architecture, and an efficient implementation of our counting algorithm -- as well as its space and time complexity. We also show how our system ensures the privacy of people in the monitored area. Finally, we validate our system using nine weeks of data from a public library endowed with a camera-based counting system, which generates counts against which we compare those of our counting system. This comparison empirically quantifies the accuracy of our counting system, thereby showing it to be suitable for monitoring public areas. Similarly, the concentration inequality provides a theoretical validation of the system.

description: Silver paint has been tested as a soldering agent for DyBaCuO single-domain welding. Junctions have been manufactured on Dy-Ba-Cu-O single-domains cut either along planes parallel to the c-axis or along the ab-planes. Microstructural and superconducting characterisations of the samples have been performed. For both types of junctions, the microstructure in the joined area is very clean: no secondary phase or Ag particles segregation has been observed. Electrical and magnetic measurements for all configurations of interest are reported $ρ(T)$ curves, and Hall probe mapping). The narrow resistive superconducting transition reported for all configurations shows that the artificial junction does not affect significantly the measured superconducting properties of the material.

description: We derive the effective long-wavelength Euclidean action for the antiferromagnetic spin-waves of ordered quantum antiferromagnets subject to a uniform magnetic field. We point out that the magnetic field dependence of the spin-wave dispersion predicted by the usual O(3)-quantum nonlinear sigma model disagrees with spin-wave theory. We argue that the nonlinear sigma model does not take into account all relevant spin-wave interactions and derive a modified effective action for the long-wavelength spin-waves which contains an additional quartic interaction. At zero temperature the corresponding vertex is relevant in the renormalization group sense below three dimensions.

description: Annual time series data for the period 1950-51 through 1975-76 are used to estimate the price elasticity of aggregate Australian agricultural supply using two methods. The short-run elasticity is estimated to be highly inelastic but it has been increasing through time. The preferred estimate of the long-run elasticity is in the relatively inelastic range and it has also been increasing through time. Some implications of these results for intersectoral resource flows and compensatory assistance, the cost-price squeeze, the effects of the mineral boom and monetary policy are discussed.

description: We obtain estimates for derivative and cross--ratio distortion for $C^{2+η}$ (any $η>0$) unimodal maps with non--flat critical points. We do not require any `Schwarzian--like' condition. For two intervals $J \subset T$, the cross--ratio is defined as the value $$B(T,J):=\frac{|T||J|}{|L||R|}$$ where $L,R$ are the left and right connected components of $T\setminus J$ respectively. For an interval map $g$ \st $g_T:T \to \RRR$ is a diffeomorphism, we consider the cross--ratio distortion to be $$B(g,T, J):=\frac{B(g(T),g(J))}{B(T,J)}.$$ We prove that for all $0 K.$$ Then the distortion of derivatives of $f^n|_J$ can be estimated with the Koebe Lemma in terms of $K$ and $B(f^n(T),f^n(J))$. This tool is commonly used to study topological, geometric and ergodic properties of $f$. This extends a result of Kozlovski.

The intermarriage experiences of four Chinese Canadian women
Creators: name: Lai, Sylvia H. G.
Publisher: name: University of British Columbia
Year: 2009

description: This study examined the marriage experiences of four Chinese Canadian women who are married to Caucasian husbands in Canada. Employing a phenomenological qualitative approach, in - depth interviews were conducted with these women in the ethnically diverse city of Vancouver, exploring their lived experiences in these relationships. The findings in this study reflect upon this and tries to bring some understanding to this rather complex phenomenon. The first finding is the non - accidental nature in who we choose to bring into our world. This important element was highlighted in the findings as it speaks to the reasons why we seek certain people to be in our life, including our spouses. The women in this study all spoke about early influences and experiences which reflected a sense of being an outsider in their own world at some point. These experiences have in one form or another shaped how these women approached relationships and in particular marriage. The second finding speaks to the effortlessness which these women present when moving between their Chinese and Canadian culture. The skills of negotiating and interpreting were highlighted by one of the women as a role that she has grown up with but now also finds useful in her marriage. This role appears almost invisible to most people because of the way these women incorporate it into their day to day living. The last major finding is the importance of seeking a balance between the two cultures in intermarriage. In doing so, it allowed the women in this study to find a safe place for them to freely express the two sided nature of their culture which up until then remained separated. In some cases it also provided the impetus to revisit their culture of origin to rework another understanding of the role of Chinese culture in their lives. The findings of this study provide a beginning understanding into the work which these four women negotiated in intermarriage to achieve a balance between the Canadian and Chinese cultures in which they live. The findings from this study bridge a gap in the understanding of the phenomenon of interracial relationships in Canada and contribute to a broader cross cultural practice in social work and family therapy.

description: Efficient allocation of resources has usually been couched in risk less terms, partly because statistical techniques did not exist for measuring the impact of varying levels of factors of production on risks associated with production. Now that such techniques are available, methods are required for determining efficient allocations. Such models, particularly those exploiting stochastic efficiency analysis, are illustrated here with respect to empirical risk-sensitive, farm-firm production functions.
Nonminimal dyons with regular gravitational, electric and axion fields

description: We consider the distribution of the axionic dark matter and the profiles of the axionically induced electric field on the background of a regular magnetic monopole. The background static spherically symmetric spacetime is considered to be regular at the center of the object and has no event horizons, the nonminimal interaction of strong gravitational and monopole type magnetic fields being the source, which provides this regularity. We assume that the pseudoscalar (axion) field also is nonminimally coupled to the electromagnetic and gravitational fields, and we search for solutions to the extended equations of nonminimal axion electrostatics, which satisfy two requirements: first, the axionically induced radial electric field vanishes at the center; second, the pseudoscalar field is regular at the center of the formed axionic dyon. We have found the set of parameters, describing the nonminimal axion-photon coupling, for which both requirements are satisfied. Properties of the two-parameter family of regular solutions to the equations of nonminimal axion electrostatics are analyzed numerically. The regular axionically induced electric field is shown to have the structure, which is typical for a simple electric layer.

description: Dynamics of spiral waves in perturbed, e. g. slightly inhomogeneous or subject to a small periodic external force, two-dimensional autowave media can be described asymptotically in terms of Aristotelean dynamics, so that the velocities of the spiral wave drift in space and time are proportional to the forces caused by the perturbation. The forces are defined as a convolution of the perturbation with the spiral's Response Functions, which are eigenfunctions of the adjoint linearised problem. In this paper we find numerically the Response Functions of a spiral wave solution in the classic excitable FitzHugh-Nagumo model, and show that they are effectively localised in the vicinity of the spiral core.

description: Attitudes toward risk are explored for a sample of rice growers on small farms in Nepal, in the context of the subjective expected utility maximisation model. Farmers are found to be generally averse to risk, with diverse levels of absolute risk aversion that tend to diminish as wealth increases, both for individuals and in a cross-sectional sense. Relative risk aversion is argued to be the most comparable measure for contrasts of attitudes toward risk.

description: Exchange-coupled nanocomposites are considered as the most promising materials for production of high-energy performance permanent magnets, which can exceed neodymium ones in terms of energy product. In this work, micromagnetic simulations of L10-FeNi/SmCo5 composites based on the initially anisotropic structure of nanorods array were performed. Texturing effect on magnetic properties was investigated. It was revealed that even 30 % of anisotropy axes misalignment of grains in L10-FeNi phase would lead to only 10 % drop of coercivity. To maximize magnetic properties of the composites, parameters of microstructure were optimized for 120 x 120 array of interacting nanorods and were found to be 40 nm nanorod diameter and 12-20 nm interrod distance. The estimated diameter of nanorods and the packing density of the array provide energy product values of 149 kJ m-3. Influence of interrod distance on energy product values was explored. Approaches for production of exchange-coupled composites based on anisotropic nanostructures were proposed.

description: Predictive process monitoring is a central practice in business process management that allows for
 the timely identification of errors, bottlenecks or deviations in process behavior, i.e. actionable
 information. Established predictive monitoring methods use event data extracted from Workflow
 Management Systems in which the case is perceived as the primary element of the process and
 as a result are approached under the wrong assumption that cases behave in isolation. Because
 of this intra-case perspective, current predictive monitoring techniques are not able to detect
 inter-case dynamics that do emerge in organizational processes such as batching. In this thesis
 we address the need for the awareness of inter-case dynamics in the development life cycle of
 predictive monitoring approaches specifically aimed at remaining time prediction. We propose a
 first set of techniques that together introduce inter-case dynamics in the remaining time prediction
 life cycle. We present techniques for identifying sub-sets of cases with high prediction errors that
 are subject to these inter-case dynamics and we present techniques that use these insights to create
 inter-case features and derive an inter-case evaluation specifically for inter-case dynamics caused
 by batching. In an experimental setup we show that by applying this set of techniques, we are
 able to improve prediction performance and a better evaluation thereof, leading to more adequate
 and better explainable models and results.

description: This paper focusses on the barely understood gap between the weakly nonlinear regime of structure formation and the onset of the virialized regime. While the former is accessed through perturbative calculations and the latter through virialization conditions incorporating dynamical stresses that arise in collisionless self-gravitating systems due to velocity dispersion forces, the addressed regime can only be understood through non-perturbative models. We here present an exact Lagrangian integral that provides a tool to access this regime. We derive a transport equation for the peculiar-gravitational field strength and integrate it along comoving trajectories of fluid elements. The so-obtained integral provides an exact expression that solves the longitudinal gravitational field equation in general. We argue that this integral provides a powerful approximation beyond the Lagrangian perturbative regime, and discuss its relation to known approximations, among them Lagrangian perturbation solutions including the Zel'dovich approximation and approximations for adhesive gravitational clustering, including the adhesion approximation. Furthermore, we propose an iteration scheme for a systematic analytical and numerical construction of trajectory fields. The integral may also be employed to improve inverse reconstruction techniques.

Multi-Objective Optimisation of Multi-Output Neural Trees
Creators: name: Ojha, Varun

Publisher: name: arXiv
Year: 2020
Subjects: subject: Neural and Evolutionary Computing (cs.NE)
subject: FOS: Computer and information sciences

description: We propose an algorithm and a new method to tackle the classification problems. We propose a multi-output neural tree (MONT) algorithm, which is an evolutionary learning algorithm trained by the non-dominated sorting genetic algorithm (NSGA)-III. Since evolutionary learning is stochastic, a hypothesis found in the form of MONT is unique for each run of evolutionary learning, i.e., each hypothesis (tree) generated bears distinct properties compared to any other hypothesis both in topological space and parameter-space. This leads to a challenging optimisation problem where the aim is to minimise the tree-size and maximise the classification accuracy. Therefore, the Pareto-optimality concerns were met by hypervolume indicator analysis. We used nine benchmark classification learning problems to evaluate the performance of the MONT. As a result of our experiments, we obtained MONTs which are able to tackle the classification problems with high accuracy. The performance of MONT emerged better over a set of problems tackled in this study compared with a set of well-known classifiers: multilayer perceptron, reduced-error pruning tree, naive Bayes classifier, decision tree, and support vector machine. Moreover, the performances of three versions of MONT's training using genetic programming, NSGA-II, and NSGA-III suggest that the NSGA-III gives the best Pareto-optimal solution.

description: Autoregressive modeling has traditionally been concerned with time-series data from one unit (N = 1). For short time series (T T, another source of information is often available for model estimation, that is, the persons (N > 1). In this work, we illustrate the N/T compensation effect: With an increasing number of persons N at constant T, the model estimation performance increases, and vice versa, with an increasing number of time points T at constant N, the performance increases as well. Based on these observations, we develop sample size recommendations in the form of easily accessible N/T heatmaps for two popular autoregressive continuous-time models.

description: The implications of alternative disturbance specifications in supply functions have been considered in recent theoretical work but little, if any, empirical evidence has been provided on such specifications. Any empirical investigation of the nature of a supply function disturbance is hampered by considerable uncertainty about the deterministic part of the function. Nevertheless, some progress might be made by considering alternative disturbance specifications in conjunction with a variety of deterministic specifications. Applying this approach to the supply of wheat in southern N.S.W., we find some empirical support for an additive disturbance and, surprisingly, for the use of price, rather than revenue, as an argument In supply functions.

description: The Wheeler-DeWitt equation of Friedmann models with a massless quantum field is formulated with arbitrary factor ordering of the Hamiltonian constraint operator. A scalar product of wave functions is constructed, giving rise to a probability interpretation and making comparison with the classical solution possible. In general the bahaviour of the wave function of the model depends on a critical energy of the matter field, which, in turn, depends on the chosen factor ordering. By certain choices of the ordering the critical energy can be pushed down to zero.

description: We introduce a class of partial correlation network models with a community structure for large panels of time series. In the model, the series are partitioned into latent groups such that correlation is higher within groups than between them.

The methodology is used to study real activity clustering in the United States.

description: Classifying multi-temporal scene land-use categories and detecting their semantic scene-level changes for imagery covering urban regions could straightly reflect the land-use transitions. Existing methods for scene change detection rarely focus on the temporal correlation of bi-temporal features, and are mainly evaluated on small scale scene change detection datasets. In this work, we proposed a CorrFusion module that fuses the highly correlated components in bi-temporal feature embeddings. We firstly extracts the deep representations of the bi-temporal inputs with deep convolutional networks. Then the extracted features will be projected into a lower dimension space to computed the instance-level correlation. The cross-temporal fusion will be performed based on the computed correlation in CorrFusion module. The final scene classification are obtained with softmax activation layers. In the objective function, we introduced a new formulation for calculating the temporal correlation. The detailed derivation of backpropagation gradients for the proposed module is also given in this paper. Besides, we presented a much larger scale scene change detection dataset and conducted experiments on this dataset. The experimental results demonstrated that our proposed CorrFusion module could remarkably improve the multi-temporal scene classification and scene change detection results.

description: We present Infrared Array Camera (IRAC) data and source catalogs from the Spitzer Space Telescope Extragalactic First Look Survey. The data were taken in four broad bands centered at nominal wavelengths of 3.6, 4.5, 5.8 and 8.0 microns. A set of mosaics and catalogs have been produced which are ~80% complete and ~99% reliable to their chosen flux density limits. The main field survey covers 3.8 deg^2, and has flux density limits of 20muJy, 25muJy, 100muJy and 100muJy at wavelengths of 3.6, 4.5, 5.8 and 8.0 microns,respectively. The deeper ``verification'' survey covers 0.25 deg^2 with limits of 10muJy, 10muJy, 30muJy and 30muJy, respectively. We also include deep data in the ELAIS-N1 field which covers 0.041deg^2 with limits of 4muJy, 3muJy, 10muJy and 10muJy, respectively, but with only two wavelength coverage at a given sky position. The final bandmerged catalogs contain 103193 objects in the main field, 12224 in the verification field and 5239 in ELAIS-N1. Flux densities of high signal-to-noise objects are accurate to about 10%, and the residual systematic error in the absolute flux density scale is ~2-3%. We have successfully extracted sources at source densities as high as 100000 deg^-2 in our deepest 3.6 and 4.5 micron data. The mosaics and source catalogs will be made available through the Spitzer Science Center archive and the Infrared Science Archive.

Japan's "last man" : overcoming a "crisis of ideas"
Creators: name: Polakoff, Gregory Ivan
Publisher: name: University of British Columbia
Year: 2009

description: Due to Mori Ogai's importance not only as a writer, but as one of Japan's leading medical researchers and cultural critics, his works have always been under the scrutiny of scholars. This is especially true with respect to the fiction composed during a short segment of his career-from 1909 to 1912-which Richard Bowring has labelled Mori Ogai's "literature of ideas." Ogai's "literature of ideas" depicts an enormous and heterogeneous array of ideas from a variety of humanistic and scientific disciplines, and is expressed in a variety of genres and literary styles. They represent Mori Ogai's keen interest in a variety of Western literary and philosophical discourses, such as Naturalism, the Bildungsroman, and the cultural criticism of such thinkers as Nietzsche and Ibsen. Although the importance of Mori Ogai's reception of Friedrich Nietzsche's ideas has been discussed to a limited degree in several studies, I intend to demonstrate that Nietzsche's ideas actually constitute a significant influence on the manner in which Ogai fine-tuned the structure, style, and content of his "literature of ideas." I believe that Ogai's "literature of ideas" is a definitive response to its author's disapproval of the outright "imitation" of Western ideas, which he perceived dominated Japan's modernization process. In addition, he was very wary of the consequences of imitating a discourse which he believed was characterized by a paradoxical union of optimistic and nihilistic ideologies. Although Mori Ogai expressed envy at the progress-oriented nature of Western ideas and the philosophies of inspiring and forward-looking thinkers such as Plato and Goethe, he was also deeply disturbed by the gradual manifestation of pessimistic thought subsequent to the Renaissance-a phenomenon which he feared could be replicated in Japan. I will argue that Nietzsche's notion of continuous self-development as depicted in Zarathustra is at the core of Ogai's "literature of ideas," the primary purpose of which is to depict Ogai's anxiety about Japan's modernization, and to posit a perspective which might help the Japanese intelligentsia to "overcome" the many obstacles which Ogai perceived as inherent components in this process.

description: Chinese livestock products consumption behavior was analysed for both urban and rural households using a complete regional consumption dataset. Six livestock product expenditure share equations were estimated with an extended AIDS model. The results suggest that Chinese consumers will continue to increase their consumption of livestock products, but consumption patterns have changed in the 1990s. A large percentage of household livestock product expenditure is still on pork. However, the shares for beef, dairy products and poultry consumption will increase substantially. As a consequence the pork expenditure share will be gradually reduced as incomes grow and diet preferences change in both urban and rural households. There are significant differences in livestock product consumption preferences across provinces of China. As a result, studies that omit regional dummy variables in their demand systems can produce different expenditure and price parameters, which should be interpreted with caution.

description: High dimensional covariance matrices appear in many disciplines. Much literature has devoted to the research in high dimensional constant covariance matrices. However, constant covariance matrices are not sufficient in applications, e.g. in portfolio allocation, dynamic covariance matrices would be more appropriate. As argued in this paper, there are two difficulties in the introduction of dynamic structures into covariance matrices: (1) simply assuming each entry of a covariance matrix is a function of time to introduce the dynamic needed would not work; (2) there is a risk of having too many unknowns to estimate due to the high dimensionality. In this paper, we propose a dynamic structure embedded with a homogeneous structure. We will demonstrate the proposed dynamic structure makes more sense in applications and avoids, in the meantime, too many unknown parameters/functions to estimate, due to the embedded homogeneous structure. An estimation procedure is also proposed to estimate the proposed high dimensional dynamic covariance matrices, and asymptotic properties are established to justify the proposed estimation procedure. Intensive simulation studies show the proposed estimation procedure works very well when the sample size is finite. Finally, we apply the proposed high dimensional dynamic covariance matrices to portfolio allocation. It is interesting to see the resulting portfolio yields much better returns than some commonly used ones.

description: The thermal characterization of bolometers is needed for optimal design as well as applications. In this letter, we present results of the effect of environment on the thermal properties of micromachined bolometers. We find that while in vacuum, the thermal response can be represented by a single time constant, in presence of an ambient gas, the thermal response can no longer be described by a single time constant. This will have a direct implication on frequency dependence of responsivity. We present a model to explain our data which involves the finite diffusion time in the ambient gas and the associated extra thermal mass.

description: China has been rapidly increasing its consumption and imports of dairy products in recent years. A two-stage demand system was estimated for livestock product consumption in urban China over the 1990s. Total expenditure elasticities for the livestock commodity group and expenditure elasticities for dairy products within the livestock commodity group were calculated. The results suggest that dairy products, even in urban areas, remain luxury goods because of a high expenditure elasticity (1.26). Due to rapidly increasing consumption and the likelihood of inadequate supply growth, China will continue to increase its imports of dairy products to meet its domestic demand. Projections imply that China's imports of dairy products may approach 30 percent of its total domestic consumption by 2005. Due to differences in regional income and population growth rates, increases in dairy products consumption may occur especially in central and coastal areas, where potential trade opportunities may exist.

description: Inspired by the observed $X(2900)$, we study systematically the mass spectra of the ground pentaquark states with the $qqqq\bar{Q}$ ($Q=c,b$; $q=n,s$; $n=u,d$) configuration in the framework of the Chromomagnetic Interaction model. We present a detailed analysis of their stabilities and decay behaviors. Our results indicate that there may exist narrow states or even stable states. We hope that the present study may inspire experimentalist's interest in searching for such a type of the exotic pentaquark state.

description: Studies of total factor productivity in livestock production are rare, but when available provide useful information especially in the context of developing countries such as China where livestock is becoming more important in the domestic agricultural economy. We estimate total factor productivity (TFP) for four major livestock products in China and by employing the random coefficient frontier approach, decompose productivity growth into its technical efficiency and technical progress components. Efforts were made to adjust and augment the available livestock statistics. The results show that growth in TFP and its components varied between the 1980s and the 1990s as well as over production structures. While there is evidence of considerable technical innovation in China's livestock sector, technical efficiency improvement was relatively slow.

description: The purpose of this work is to discuss recent progress in deriving the fundamental laws of thermodynamics (0th, 1st and 2nd-law) from nonequilibrium quantum statistical mechanics. Basic thermodynamic notions are clarified and different reversible and irreversible thermodynamic processes are studied from the point of view of quantum statistical mechanics. Special emphasis is put on new adiabatic theorems for steady states close to and far from equilibrium, and on investigating cyclic thermodynamic processes using an extension of Floquet theory.

description: Laser decoherence limits the stability of optical clocks by broadening the observable resonance linewidths and adding noise during the dead time between clock probes. Correlation spectroscopy avoids these limitations by measuring correlated atomic transitions between two ensembles, which provides a frequency difference measurement independent of laser noise. Here, we apply this technique to perform stability measurements between two independent clocks based on the $^1S_0\leftrightarrow{}^3P_0$ transition in $^{27}$Al$^+$. By stabilizing the dominant sources of differential phase noise between the two clocks, we observe coherence between them during synchronous Ramsey interrogations as long as 8 s at a frequency of $1.12\times10^{15}$ Hz. The observed contrast in the correlation spectroscopy signal is consistent with the 20.6 s $^3P_0$ state lifetime and supports a measurement instability of $(1.8\pm0.5)\times 10^{-16}/\sqrt{τ/\textrm{s}}$ for averaging periods longer than the probe duration when deadtime is negligible.

description: Ecologists frequently note the importance of modelling entire ecosystems rather than single species, but most bioeconomic models in the current literature focus on a single species. While the mathematical difficulty of multiple species may quickly become overwhelming, sometimes making the single species option necessary, it is important to recognise the significance of the single species assumption to the model results. In this paper, the authors address the economic significance of this assumption through the development of a multiple species model and demonstrate the importance of interrelationships and economic values to the survival of endangered species.
Proper Motion of H2O Masers in IRAS 20050+2720 MMS1: An AU Scale Jet Associated with An Intermediate-Mass Class 0 Source

description: We conducted a 4 epoch 3 month VLBA proper motion study of H$_2$O masers toward an intermediate-mass class 0 source IRAS 20050+2720 MMS1 (d=700 pc). From milli-arcsecond (mas) resolution VLBA images, we found two groups of H2O maser spots at the center of the submillimeter core of MMS1. One group consists of more than $\sim 50$ intense maser spots; the other group consisting of several weaker maser spots is located at 18 AU south-west of the intense group. Distribution of the maser spots in the intense group shows an arc-shaped structure which includes the maser spots that showed a clear velocity gradient. The spatial and velocity structures of the maser spots in the arc-shape did not significantly change through the 4 epochs. Furthermore, we found a relative proper motion between the two groups. Their projected separation increased by 1.13+/-0.11 mas over the 4 epochs along a line connecting them. The spatial and velocity structures of the intense group and the relative proper motions strongly suggest that the maser emission is associated with a protostellar jet. Comparing the observed LSR velocities with calculated radial velocities from a simple biconical jet model, we conclude that the most of the maser emission are likely to be associated with an accelerating biconical jet which has large opening angle. The large opening angle of the jet traced by the masers would support the hypothesis that poor jet collimation is an inherent property of luminous (proto)stars.

description: We consider electrogeodesics on which the energy $E<0$ in the Reissner-Nordström metric. It is shown that outside the horizon there is exactly one turning point inside the ergoregion for such particles. This entails that such a particle passes through an infinite chain of black-white hole regions or terminates in the singularity. These properties are relevant for two scenarios of high energy collisions in which the presence of white holes is essential.
