description: Using $HST$/COS observations of the twin quasar lines of sight Q$0107-025$A $\&$ Q$0107-025$B, we report on the physical properties, chemical abundances and transverse sizes of gas in a multiple galaxy environment at $z = 0.399$ across a transverse separation of $520$ kpc. The absorber towards Q$0107-025$B has $\log N(H I)/cm^{-2} \approx 16.8$ (partial Lyman limit) while the absorber towards the other sightline has $N(H I) \approx 2$ dex lower. The O VI along both sightlines have comparable column densities and broad $b$-values, whereas the low ionization lines are considerably narrower. The low ionization gas is inconsistent with the O VI when modelled assuming photoionization in a single phase. Along both the lines-of-sight, O VI and coinciding broad H I are best explained through collisional ionization in a cooling plasma with solar metallicity. Ionization models infer $1/10$-th solar metallicity for the pLLS and solar metallicity for the lower column density absorber along the other sightline. Within $\pm~250~km~s^{-1}$ and $2$ Mpc of projected distance from the sightlines 12 galaxies are identified, of which 3 are within $300$ kpc. One of them is a dwarf galaxy while the other two are intermediate mass systems at impact parameters of $ρ\sim (1-4)R_{vir}$. The O VI along both lines-of-sight could be either tracing narrow transition temperature zones at the interface of low ionization gas and the hot halo of nearest galaxy, or a more spread-out warm gas bound to the circumgalactic halo/intragroup medium. This latter scenario leads to a warm gas mass limit of $M \gtrsim 4.5 \times 10^{9}$ M$_\odot$.

description: We develop a microscopic theory for plasmon excitations of graphene/$α$-RuCl${_3}$ heterostructures. Within a Kondo-Kitaev model with various interactions, a heavy Fermi liquid hosting flat bands emerges in which the itinerant electrons of graphene effectively hybridize with the fractionalized fermions of the Kitaev quantum spin liquid. We find novel correlated plasmon bands induced by the interplay of flat bands and interactions and argue that our theory is consistent with the available experimental data on graphene/$α$-RuCl${_3}$ heterostructures. We predict novel plasmon branches beyond the long-wavelength limit and discuss the implications for probing correlation phenomena in other flat band systems.

Magnetohydrostatic Equilibrium Structure and Mass of Polytropic Filamentary Cloud Threaded by Lateral Magnetic Field

description: Filamentary structures are recognized as a fundamental component of interstellar molecular clouds in observations by the Herschel satellite. These filaments, especially massive filaments, often extend in a direction perpendicular to the interstellar magnetic field. Furthermore, the filaments sometimes have an apparently negative temperature gradient, that is, their temperature decreases towards the center. In this paper, we study the magnetohydrostatic equilibrium state of negative-indexed polytropic gas with the magnetic field running perpendicular to the axis of the filament. The model is controlled by four parameters: center-to-surface density ratio ($ρ_c/ρ_s$), plasma $β$ of the surrounding gas, radius of the parent cloud $R'_0$ normalized by the scale height, and the polytropic index $N$. The steepness of the temperature gradient is represented by $N$. We found that the envelope of the column density profile becomes shallow when the temperature gradient is large. This reconciles the inconsistency between the observed profiles and those expected from the isothermal models. We compared the maximum line-mass (mass per unit length), above which there is no equilibrium, with that of the isothermal non-magnetized filament. We obtained an empirical formula to express the maximum line-mass of a magnetized polytropic filament as $λ_{max}\simeq\left[{\left(λ_{0,max}(N)/M_\odot{\rm pc^{-1}}\right)^2+\left[5.9(1.0+1.2/N)^{1/2}({Φ_{cl}}/{1μ{\rm G\,pc}})\right]^2}\right]^{1/2}M_\odot {\rm pc^{-1}}$, where $λ_{0,max}(N)$ represents the maximum line-mass of the non-magnetized filament and $Φ_{cl}$ indicates one-half of the magnetic flux threading the filament per unit length. Although the negative-indexed polytrope makes the maximum line-mass decrease compared with that of the isothermal model, a magnetic field threading the filament increases the line-mass.

Pedogenesis of soils derived from ultramafic rocks and tephra in southwestern British Columbia
Creators: name: Bulmer, Charles Ernest
Publisher: name: University of British Columbia
Year: 2008

description: Ultramafic rocks and soils are of interest because (1) they provide unique plant growth environments, (2) environmental hazards such as chrysotile asbestos may be present, and (3) valuable deposits of asbestos, and minerals containing Mg, Cr, Ni, Co and Pt may be present. Information on ultramafic soils is useful for alleviating environmental problems associated with ultramafic terrain, and for exploiting the opportunities associated with ultramafic mineral deposits. This thesis presents new information on the weathering status of ultramafic soils that formed since the most recent advance of continental ice sheets in southwestern British Columbia. The effects of eolian and tephra additions on soil formation were also described, and soil processes in ultramafic- and tephra-derived soils were compared. A total of 27 soil profiles were described and sampled at three areas in southwestern British Columbia. Brunisolic soils with composite profiles of tephra overlying serpentinite covered much of the Shulaps ultramafic complex. These soils developed in a dry environment and showed weak profile development. The Tulameen area was characterized by a moderately dry climate, and Brunisolic soils had developed in serpentinized peridotite and dunite. The soils of the Coquihalla serpentine belt had Podzolic profiles which resulted from intense weathering in a moist environment. The weathering status of the soils was investigated using a variety of chemical and mineralogical techniques. Chlorite and mica weathering was observed in clay fractions for the Podzolic soils at the Coquihalla area, while profiles from the Shulaps area had similar clay mineralogy throughout the profiles, as determined by XRD. Serpentine dissolution was indicated by chemical analysis of upland soil profiles. Weathering and leaching depleted Mg from B horizons relative to parent materials. Nickel and Co were redistributed to the C horizons in all but the driest environments, while Mn was less mobile. Chromium was retained in the B horizons of all profiles. The influence of tephra on ultramafic paleosols was minimal, but the addition of colluvial and eolian ultramafic materials to the tephra-derived soils gave rise to soils with the cation exchange complex dominated by Mg, which is more typical of ultramafic soils. Lack of buried organic layers in ultramafic paleosols was interpreted as evidence that modern-day tephra soils in the Shulaps Range were more productive than the ancient ultramafic soils. Weathering experiments showed that trace metals such as Cr, Mn, Co and Ni were preferentially released from serpentine to dilute citric acid solutions compared to major elements such as Mg, Si, and Fe. The results suggest that these potentially toxic trace metals may be released in significant amounts in the early stages of pedogenesis.
A Condense-then-Select Strategy for Text Summarization

Year: 2021
Subjects: subject: Computation and Language (cs.CL)
subject: FOS: Computer and information sciences

description: Select-then-compress is a popular hybrid, framework for text summarization due to its high efficiency. This framework first selects salient sentences and then independently condenses each of the selected sentences into a concise version. However, compressing sentences separately ignores the context information of the document, and is therefore prone to delete salient information. To address this limitation, we propose a novel condense-then-select framework for text summarization. Our framework first concurrently condenses each document sentence. Original document sentences and their compressed versions then become the candidates for extraction. Finally, an extractor utilizes the context information of the document to select candidates and assembles them into a summary. If salient information is deleted during condensing, the extractor can select an original sentence to retain the information. Thus, our framework helps to avoid the loss of salient information, while preserving the high efficiency of sentence-level compression. Experiment results on the CNN/DailyMail, DUC-2002, and Pubmed datasets demonstrate that our framework outperforms the select-then-compress framework and other strong baselines.

Sunn-hemp mosiac virus as a helper in the intercellular spread of southern bean mosaic in a resistant host
Creators: name: Fuentes, Ana Lucía
Publisher: name: University of British Columbia
Year: 2008

description: Four bean cultivars (“Bountiful”, “Pinto”, “Top Crop”, and “Tendergreen”) allowed only subliminal replication of the cowpea strain of southern bean mosaic virus (SBMV-C). Bean protoplasts, on the other hand, sustained replication of SBMV-C upon in vitro inoculation. Antigen accumulation of the bean strain of southern bean mosaic virus (SBMV-B) and SBMV-C in bean protoplasts was similar, indicating that the replicating capacity of both viruses does not differ in bean cells. When the four bean cultivars were inoculated with a mixture of sunn hemp mosaic virus (SH1VIV), a tobamovirus, and SBMV-C, the latter was readily detected in the inoculated primary leaves. The rate of spread of SBMV-C in the presence of SHMV was compared to the rate of spread of SBMV-B in bean co inoculated with SHMV. Virus accumulation in leaf blades, lateral veins, mid-ribs, petioles, stems and roots was similar for both strains in the non-vascular tissue of the inoculated leaf; a sharp decline in SBMV-C accumulation was observed starting from the lateral veins towards the mid and distal parts of the petiole, where virtually no virus could be found. These results contrasted with the uniform presence of SBMV-B throughout infected bean plants. Leaf strips blotted on nitrocellulose paper and developed as for Western blotting confirmed these results, with SBMV-C antigen being detected in mesophyll tissue and in epidermal cells of the lateral veins of the inoculated primary leaves. Electron micrographs of immunogold-labelled sections revealed the absence of uniform SBMV-C particles in the mesophyll cells; instead, heavily labelled, amorphous protein clumps in the vacuole were found. SBMV-C coat protein from infected cowpea and bean plants showed no difference in its mobility during electrophoresis in denaturing polyacrylamide gels. These results indicate that SHMV facilitates cell to cell spread of SBMV-C in inoculated bean leaves but does not allow for the movement of the latter through the vascular system. Lack of efficient assembly of SBMV-C does not impede cell-to-cell movement of the virus in the doubly-infected leaves, yet it is probably an important factor involved in determining the inability of SBMV-C to move into and/or through the vascular system.

description: Natural Language Video Description (NLVD) has recently received strong interest in the Computer Vision, Natural Language Processing (NLP), Multimedia, and Autonomous Robotics communities. The State-of-the-Art (SotA) approaches obtained remarkable results when tested on the benchmark datasets. However, those approaches poorly generalize to new datasets. In addition, none of the existing works focus on the processing of the input to the NLVD systems, which is both visual and textual. In this work, it is presented an extensive study dealing with the role of the visual input, evaluated with respect to the overall NLP performance. This is achieved performing data augmentation of the visual component, applying common transformations to model camera distortions, noise, lighting, and camera positioning, that are typical in real-world operative scenarios. A t-SNE based analysis is proposed to evaluate the effects of the considered transformations on the overall visual data distribution. For this study, it is considered the English subset of Microsoft Research Video Description (MSVD) dataset, which is used commonly for NLVD. It was observed that this dataset contains a relevant amount of syntactic and semantic errors. These errors have been amended manually, and the new version of the dataset (called MSVD-v2) is used in the experimentation. The MSVD-v2 dataset is released to help to gain insight into the NLVD problem.

We determine and characterize the existence of an universe with $Ω> 1$, and which describes a period of inflation. We find that considered models are less restrictive compared to the standard ones with a scalar field. We use recent astronomical observations to constraint the parameters appearing in the model. Obtained results are compared to those found in the standard scalar field inflationary universes.

description: We study the motion of a charged particle with magnetic moment in external electromagnetic fields utilizing covariant unification of Gilbertian and Amperian descriptions of particle magnetic dipole moment. Considering the case of a current loop, our approach is verified by comparing classical dynamics with the classical limit of relativistic quantum dynamics. We obtain motion of a charged particle in the presence of an external linearly polarized EM (laser) plane wave field incorporating the effect of spin dynamics. For specific laser-particle initial configurations, we determine that the Stern-Gerlach force can have a cumulative effect on the trajectory of charged particles.

description: Particle volatility, size distribution, and parent and alkylated polycyclic aromatic hydrocarbon (PAH/alkyl-PAH) profiles during toluene pyrolysis in a flow reactor were studied. The experiments were conducted under three different gas residence times (0.2, 0.5 and 0.8 s) at temperatures from 950 to 1450 °C. Results showed that long residence times and high temperatures led to high particle mass concentrations, low particle volatility and a significant shift of particle size distribution to larger size. Total particle number concentrations exhibited a rise-then-fall trend (peaking at a critical temperature of 1050 °C) with increasing temperature, indicating that increasing temperature promoted a transition from nucleation to agglomeration and coagulation which dominated the particle size distributions. Among PAHs and alkyl-PAHs, those with 2–4 rings, presented the highest concentrations at 950 °C for 0.2 s. They appeared at 1050 °C for 0.5 and 0.8 s, consistent with the critical temperature of particle nucleation at long residence times (0.5 and 0.8 s). Particle peak number concentrations and total PAH mass concentrations exhibited consistent temperature dependence, indicating soot nucleation was highly related to PAH concentrations. According to the comprehensive observations in this study, low molecular mass PAHs instead of larger PAHs appear to be the precursors of soot formation during high temperature pyrolysis processes.

description: In deep near-infrared imaging of the low-metallicity (${\rm [O/H]}=-0.7$ dex) H II region Sh 2-127 (S127) with Subaru/MOIRCS, we detected two young clusters with 413 members (S127A) in a slightly extended H II region and another with 338 members (S127B) in a compact H II region. The limiting magnitude was $K=21.3$ mag (10$σ$), corresponding to a mass detection limit of $\sim$0.2 $M_\odot$. These clusters are an order of magnitude larger than previously studied young low-metallicity clusters and larger than the majority of solar neighborhood young clusters. Fits to the K-band luminosity functions indicate very young cluster ages of 0.5 Myr for S127A and 0.1-0.5 Myr for S127B, consistent with the large extinction (up to $A_V\simeq20$ mag) from thick molecular clouds and the presence of a compact H II region and class I source candidates, and suggest that the initial mass function (IMF) of the low-metallicity clusters is indistinguishable from typical solar neighborhood IMFs. Disk fractions of $28\% \pm 3\%$ for S127A and $40\% \pm 4\%$ for S127B are significantly lower than those of similarly aged solar neighborhood clusters ($\sim$50$\%$-60$\%$). The disk fraction for S127B is higher than those of previously studied low-metallicity clusters ($

description: Applying any strategy requires some knowledge about the past state of the system. Unfortunately in the case of economy collecting information is a difficult, expensive and time consuming process. Therefore the information about the system is known at the end of some well defined intervals, e. g. company reports, inflation data, GDP etc. They describe a (market) situation in the past. The time delay is specific to the market branch. It can be very short (e.g. stock market offer is updated every minute or so and this information is immediately available) or long, like months in the case of agricultural market, when the decisions are taken based on the results from the previous harvest. The analysis of the information flow delay can be based on the ACP model of spatial evolution of economic systems. The entities can move on a square lattice and when meeting take one of the two following decisions: merge or create a new entity. The decision is based on the system state, which is known with some time delay. The effect of system's feedback is investigated. We consider the case of company distribution evolution in a heterogenous field. The information flow time delay implies different final states, including cycles.

description: The reaction of Schiff base 2-(4-(dimethylamino)benzylideneamino)phenol (DBAP) and diethylenetriamine/ethylenediamine with cobalt(II) and copper(II) metal ion in equimolar ratio afforded mixed ligand complexes [M(DBAP)(L)Cl(H2O)n] (1–4), where M = Co(II) 1, 2; Cu(II) 3, 4; L = diethylenetriamine (1, 3); n = 0 and ethylenediamine (2, 4); n = 1. All the newly synthesized complexes were characterized by elemental analysis, spectroscopic techniques viz., UV-vis, FT-IR, ESR, PXRD and mass spectrometry. The influence of chelation of cobalt(II) and copper(II) ion on nonlinear optical properties of Schiff base (DBAP) were examined with DFT study. The polarizability (α0) and first-order hyperpolarizability (β) of ligand and their metal complexes were calculated and compared with reference molecule p-nitroaniline. The hyperpolarizability of Schiff base and their metal complexes show a good nonlinear optical behavior. Theoretical investigation of the complexes was performed by DFT using B3LYP level of theory on the basis set 6-31 G (d, p)/LanL2DZ. On the basis of spectroscopic data and DFT computation, a six-coordinate geometry is tentatively proposed around the metal ion. In vitro antibacterial activities of these complexes were also screened against V. cholerae and E. coli, and found to have good antibacterial activity.

description: With a reduction in the average grain size in nanostructured films of elemental Nb, we observe a systematic crossover from metallic to weakly-insulating behavior. An analysis of the temperature dependence of the resistivity in the insulating phase clearly indicates the existence of two distinct activation energies corresponding to inter-granular and intra-granular mechanisms of transport. While the high temperature behavior is dominated by grain boundary scattering of the conduction electrons, the effect of discretization of energy levels due to quantum confinement shows up at low temperatures. We show that the energy barrier at the grain boundary is proportional to the width of the largely disordered inter-granular region, which increases with a decrease in the grain size. For a metal-insulator transition to occur in nano-Nb due to the opening up of an energy gap at the grain boundary, the critical grain size is ~ 8nm and the corresponding grain boundary width is ~ 1.1nm.

description: Markov chains are a natural and well understood tool for describing one-dimensional patterns in time or space. We show how to infer $k$-th order Markov chains, for arbitrary $k$, from finite data by applying Bayesian methods to both parameter estimation and model-order selection. Extending existing results for multinomial models of discrete data, we connect inference to statistical mechanics through information-theoretic (type theory) techniques. We establish a direct relationship between Bayesian evidence and the partition function which allows for straightforward calculation of the expectation and variance of the conditional relative entropy and the source entropy rate. Finally, we introduce a novel method that uses finite data-size scaling with model-order comparison to infer the structure of out-of-class processes.

description: Recent experiments introducing controlled disorder into optimally doped cuprate superconductors by both electron irradiation and chemical substitution have found unusual behavior in the rate of suppression of the critical temperature Tc vs. increase in residual resistivity. We show here that the unexpected discovery that the rate of Tc suppression vs. resistivity is stronger for out-of-plane than for in-plane impurities may be explained by consistent calculation of both Tc and resistivity if the potential scattering is assumed to be nearly forward in nature. For realistic models of impurity potentials, we further show that significant deviations from the universal Abrikosov-Gor'kov Tc suppression behavior may be expected for out of plane impurities.

Something good comes out of Wessex : feminist voices in Thomas Hardy
Creators: name: Cimmarrusti, Magdalena Kristina
Publisher: name: University of British Columbia
Year: 2008

description: Hardy is often maligned by feminist readers for his portrayals of women who are punished for their refusal to submit to the patriarchal law. However, far from reasserting anti-feminist notions of women and womanhood, Hardy uses his heroines to challenge the patriarchal structuring of a society that does not recognize women's words, women's passions, or women's possibilities. Bathsheba, Tess, and Sue confront the issues of language, sexuality, and marriage from a feminist perspective, and force the reader to recognize the artificiality of the systems which uphold man as the center of a society in which woman is other. Within Far From the Madding Crowd, Tess of the d'Urbervilles, and Jude the Obscure, subversive voices speak up against the stereotypes within which women are contained and break down "the letter" of patriarchal laws which artificially characterize women as sexless and in need of the protective embrace of husband and home. Given their own voices, with which to express their own feelings and desires, these three heroines speak out against the sexist language, the stereotype of the "pure" woman, and the necessity of marriage; and though they are eventually silenced, their voices have been heard, and the reader must recognize their right to speak and to live independent of the bounds of the patriarchal law.
S-folds and holographic RG flows on the D3-brane

description: Type IIB S-folds of the form $\,\textrm{AdS}_{4} \times \textrm{S}^1 \times \textrm{S}^5\,$ are conjectured to correspond to new strongly coupled three-dimensional CFT's on a localised interface of $\,\textrm{SYM}_{4}\,$. In this work we construct holographic RG flows on the D3-brane that generically connect anisotropic deformations of $\,\textrm{SYM}_{4}\,$ in the UV to various S-fold $\textrm{CFT}$'s in the IR with different amounts of supersymmetry and flavour symmetries. Examples of holographic RG flows between \mbox{S-fold} CFT's are also presented. Lastly a geometric interpretation of axion deformations is provided in terms of monodromies on the internal $\,\textrm{S}^{5}\,$ when moving around the $\,\textrm{S}^{1}$. Special attention is paid to the monodromy-induced patterns of symmetry breaking as classified by the mapping torus $T_{h}(\textrm{S}^5)$.

Ground based gamma-ray astronomy with Cherenkov Telescopes

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Very-high-energy (>100 GeV) gamma-ray astronomy is emerging as an important discipline in both high energy astrophysics and astro-particle physics. This field is currently dominated by Imaging Atmospheric-Cherenkov Telescopes (IACTs) and arrays of these telescopes. Such arrays have achieved the best angular resolution and energy flux sensitivity in the gamma-ray domain and are still far from the fundamental limits of the technique. Here I will summarise some key aspects of this technique and go on to review the current status of the major instruments and to highlight selected recent results.

Full counting statistics for the Kondo dot in the unitary limit

description: We calculate the charge transfer probability distribution function $χ(λ)$ for the Kondo dot in the strong coupling limit within the framework of the Nozières--Fermi--liquid theory of the Kondo effect. At zero temperature, the ratio of the moments $C_n$ of the charge distribution to the backscattering current $I_{\rm bs}$ follows a universal law $C_n/2I_{\rm bs}=(-1)^n(1+2^n)/6$. The functional form of $χ(λ)$ is consistent with tunnelling of electrons and, possibly, electron pairs. We then discuss the cross-over behaviour of $χ(λ)$ from weak to strong Coulomb repulsion in the underlying Anderson impurity model and relate this to the existing results. Finally, we extend our analysis to the case of finite temperatures.

description: We introduce simplified models for enhancements in the matter power spectrum at small scales and study their implications for dark matter substructure and gravitational observables. These models capture the salient aspects of a variety of early universe scenarios that predict enhanced small-scale structure, such as axion-like particle dark matter, light vector dark matter, and epochs of early matter domination. We use a model-independent, semi-analytic treatment to map bumps in the matter power spectrum to early-forming sub-solar mass dark matter halos and estimate their evolution, disruption, and contribution to substructure of clusters and galaxies at late times. We discuss the sensitivity of gravitational observables, including pulsar timing arrays and caustic microlensing, to both the presence of bumps in the power spectrum and variations in their basic properties.

description: We discuss the recent progress and the current status of experimental investigations of spin-mediated energy transport in spin-chain and spin-ladder materials with antiferromagnetic coupling. We briefly outline the central results of theoretical studies on the subject but focus mainly on recent experimental results that were obtained on materials which may be regarded as adequate physical realizations of the idealized theoretical model systems. Some open questions and unsettled issues are also addressed.

description: Denote by an $\ell$-component a connected $b$-uniform hypergraph with $k$ edges and $k(b-1) - \ell$ vertices. We prove that the expected number of creations of $\ell$-component during a random hypergraph process tends to 1 as $\ell$ and $b$ tend to $\infty$ with the total number of vertices $n$ such that $\ell = o(\sqrt[3]{\frac{n}{b}})$. Under the same conditions, we also show that the expected number of vertices that ever belong to an $\ell$-component is approximately $12^{1/3} (b-1)^{1/3} \ell^{1/3} n^{2/3}$. As an immediate consequence, it follows that with high probability the largest $\ell$-component during the process is of size $O((b-1)^{1/3} \ell^{1/3} n^{2/3})$. Our results give insight about the size of giant components inside the phase transition of random hypergraphs.

CMB signal in WMAP 3yr data with FastICA

description: We present an application of the fast Independent Component Analysis (FastICA) to the WMAP 3yr data with the goal of extracting the CMB signal. We evaluate the confidence of our results by means of Monte Carlo simulations including CMB, foreground contaminations and instrumental noise specific of each WMAP frequency band. We perform a complete analysis involving all or a subset of the WMAP channels in order to select the optimal combination for CMB extraction, using the frequency scaling of the reconstructed component as a figure of merit. We found that the combination KQVW provides the best CMB frequency scaling, indicating that the low frequency foreground contamination in Q, V and W bands is better traced by the emission in the K band. The CMB angular power spectrum is recovered up to the degree scale, it is consistent within errors for all WMAP channel combination considered, and in close agreement with the WMAP 3yr results. We perform a statistical analysis of the recovered CMB pattern, and confirm the sky asymmetry reported in several previous works with independent techniques.

Addition-Deletion Networks

Year: 2007
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study structural properties of growing networks where both addition and deletion of nodes are possible. Our model network evolves via two independent processes. With rate r, a node is added to the system and this node links to a randomly selected existing node. With rate 1, a randomly selected node is deleted, and its parent node inherits the links of its immediate descendants. We show that the in-component size distribution decays algebraically, c_k ~ k^{-beta}, as k-->infty. The exponent beta=2+1/(r-1) varies continuously with the addition rate r. Structural properties of the network including the height distribution, the diameter of the network, the average distance between two nodes, and the fraction of dangling nodes are also obtained analytically. Interestingly, the deletion process leads to a giant hub, a single node with a macroscopic degree whereas all other nodes have a microscopic degree.
