Publisher: name: Zenodo
Year: 2024

description: The blood barriers of the nervous system are essential for protecting neural tissues and maintaining homeostasis. While the blood-brain barrier (BBB) of the central nervous system (CNS) is well characterized, comprising a monolayer of endothelial cells supported by nearly complete pericyte and astrocyte coverage, there is a lack of comparable understanding in the peripheral nervous system (PNS). 

In the CNS, the microenvironment of the BBB is critical for its barrier properties However, the structure and regulation of the blood-nerve barrier (BNB) in the PNS remain poorly understood. The BNB plays a crucial role in PNS function, yet its vascular component (EndoVs) and its cellular composition have not been described to date, despite the importance of the BNB for PNS function, with disruption associated with disorders such as diabetes and neuropathies.

description: The Probability Distribution Function of plasma density fluctuations at the edge of fusion devices is known to be skewed and strongly non-Gaussian. The causes of this peculiar behaviour are, up to now, largely unexplored. On the other hand, understanding the origin and the properties of edge turbulence is a key issue in magnetic fusion research. In this work we show that a stochastic fragmentation model, already successfully applied to fluid turbulence, is able to predict an asymmetric distribution that closely matches experimental data. The asymmetry is found to be a direct consequence of intermittency. A discussion of our results in terms of recently suggested BHP universal curve [S.T. Bramwell, P.C.W. Holdsworth, J.-F. Pinton, Nature (London) 396, 552 (1998)], that should hold for strongly correlated and critical systems, is also proposed

description: This thesis aimed to identify and compare the intercultural sensitivity,
 or IS, of

 tertiary American instructors teaching mono-national, non-American student

 populations abroad in the UAE and that of American tertiary instructors in
 multinational, non-American student populations domestically in the US.
 The study investigated the use of reflexive photography and
 photo-elicitation interviews methods as both data collection approaches
 and possible cultivators of IS, as well as any variation in findings
 between the two participant groups. The study employed a mixed-methods
 approach involving surveys and semi-structured photo-elicitation
 interviews following a four-week reflexive photography project.
 Qualitative data were analyzed through the lens of a developmental
 framework and inductively through thematic analysis to capture fuller
 images of participants’ environments. Both groups of participants
 self-report fairly high IS, with the US-based group’s sensitivity
 averaging higher than the UAE-based group. Both groups, on average, showed
 slightly increased IS quantitatively following the reflexive photography
 project and photo-elicitation interviews, with the UAE-based group
 experiencing a slightly greater increase. This research involves a small
 number of participants; findings should be considered for indicative
 purposes only. Participants’ IS, when observed through the theoretical
 lens, indicate more progressive sensitivity among US-based

 participants. Thematic analysis of interview data reflects distinct
 teaching

 contexts faced by each participant group, with five and six themes
 emerging

 from the UAE- and US-based groups, respectively. This research is the
 first to

 the best of the author’s knowledge to investigate the IS of tertiary
 American

 faculty teaching internationally diverse student populations domestically
 and is

 also the first to compare differences in IS between this group and
 American

description: Sei G eine nilpotente, zusammenhängende, einfach zusammenhängende Lie-Gruppe. Das Hauptziel dieser Doktorarbeit ist es, zu beweisen, dass die Wellenfrontmenge von einer unitären Darstellung von G gleich dem asymptotischen Kegel ihres orbitalen Trägers ist, wobei wir die von Kirillov zu den irreduziblen unitären Darstellungen assoziierten koadjungierten Orbits verwenden.Wir präsentieren zwei Herangehensweisen: erstens per Induktion über die Dimension von G wie üblich für nilpotente Lie-Gruppen und zweitens über integrierte Charaktere, wie sie von Harris, He und Olafsson für reell reduktive, algebraische Lie-Gruppen verwendet wurden. Abschließend wenden wir unser Resultat auf die Einschränkung von unitären Darstellungen auf nilpotente Untergruppen an, um asymptotische Informationen über ihren Träger zu erhalten.
description: Let G be a nilpotent, connected, simply connected Lie group. The main goal of this doctoral thesis is to prove that the wave front set of a unitary representation of G coincides with the asymptotic cone of its orbital support, where we use the coadjoint orbits associated by Kirillov to the irreducible unitary representations.We use two different approaches: by induction over the dimension of G as customary for nilpotent Lie groups and via integrated characters following the work by Harris, He and Olafsson for real reductive, algebraic Lie groups. Lastly, we apply our result to restrictions of unitary representations to nilpotent subgroups to obtain asymptotic information about their support.

description: We investigate the feasibility of simulating different model Hamiltonians used in high-temperature superconductivity. We briefly discuss the most common models and then focus on the simulation of the so-called t-J-U Hamiltonian using ultra-cold atoms in optical lattices. For this purpose, previous simulation schemes to realize the spin interaction term J are extended. We especially overcome the condition of a filling factor of exactly one, which otherwise would restrict the phase of the simulated system to a Mott-insulator. Using ultra-cold atoms in optical lattices allows simulation of the discussed models for a very wide range of parameters. The time needed to simulate the Hamiltonian is estimated and the accuracy of the simulation process is numerically investigated for small systems.

An intelligent support system for the analysis of power system transients
Creators: name: Ibrahim, Awad Ibraik
Publisher: name: University of British Columbia
Year: 2009

description: Electromagnetic transients programs such as EMTP are extensively used for simulating fast transient effects in electric power systems. However, these programs are not easy to use for the following two reasons: 1. All of them require a high level of technical expertise to apply them properly. 2. Most of them are not user friendly. This project proposes an intelligent system to support simulations with EMTP and similar programs. The work is composed of three parts; the first part presents the development of a prototype intelligent support system, the second part introduces the knowledge base for switching surge studies, and the third part describes the development of a new line model for the representation of short transmission lines and cables. The intelligent support system is composed of three stages. First, the support system selects a base case from a case database, to be modified to meet the user's requirement. Second, the expert system checks the syntax and validity of the new case data. Finally, the EMTP solution is checked to see whether the chosen models are appropriate for the frequencies contained in the solution, for the degree of imbalance, and for other criteria. If they are not appropriate, better models will be recommended to the user. The knowledge base for switching surge studies solves the problem of selecting the proper models for representing power system components in the EMTP. It helps in checking the validity of the data used to represent the simulated transient phenomena, and gives some suggestions to the user to correct his case data before simulation. It also helps in the evaluation of the results, using the knowledge of the phenomena being simulated. From this knowledge base, the idea of developing a new line model for short lines and cables evolved as one of the practical rules that is recommended for the proposed intelligent support system. The new EMTP transmission line model for the representation of short overhead lines and cables will overcome the limitation of using a time step size not larger than the travel time. The error analysis for the short and open-circuit responses shows that the new line model has a filtering effect for higher frequencies. In a comparison with actual field test measurements, it is shown that the new line model is suitable for a reasonable representation of short overhead transmission lines and cables.

description: This paper describes KIT’submission to the IWSLT 2021 Offline Speech Translation Task. We describe a system in both cascaded condition and end-to-end condition. In the cascaded condition, we investigated different end-to-end architectures for the speech recognition module. For the text segmentation module, we trained a small transformer-based model on high-quality monolingual data. For the translation module, our last year’s neural machine translation model was reused. In the end-to-end condition, we improved our Speech Relative Transformer architecture to reach or even surpass the result of the cascade system.

description: A major goal of materials design is to find material structures with desired properties and in a second step to find a processing path to reach one of these structures. In this paper, we propose and investigate a deep reinforcement learning approach for the optimization of processing paths. The goal is to find optimal processing paths in the material structure space that lead to target-structures, which have been identified beforehand to result in desired material properties. There exists a target set containing one or multiple different structures. Our proposed methods can find an optimal path from a start structure to a single target structure, or optimize the processing paths to one of the equivalent target-structures in the set. In the latter case, the algorithm learns during processing to simultaneously identify the best reachable target structure and the optimal path to it. The proposed methods belong to the family of model-free deep reinforcement learning algorithms. They are guided by structure representations as features of the process state and by a reward signal, which is formulated based on a distance function in the structure space. Model-free reinforcement learning algorithms learn through trial and error while interacting with the process. Thereby, they are not restricted to information from a priori sampled processing data and are able to adapt to the specific process. The optimization itself is model-free and does not require any prior knowledge about the process itself. We instantiate and evaluate the proposed methods by optimizing paths of a generic metal forming process. We show the ability of both methods to find processing paths leading close to target structures and the ability of the extended method to identify target-structures that can be reached effectively and efficiently and to focus on these targets for sample efficient processing path optimization.

Remarks
The genera (especially the new genera) placed within the Cyrtogomphoceratida vary widely in features, such as chamber spacing, siphuncular shape, and in conch shape. Here, following Teichert (1964b) I placed all endogastrically curved brevicones with expanded siphuncular segments into this family. A family revision and probably the erection of a new family for Hosholmoceras gen. nov. are required, but a revision of the Cyrtogomphoceratidae is beyond the scope of this work.

description: Jets launched by active galactic nuclei (AGN) are believed to play a significant role in shaping the properties of galaxies and provide an energetically viable mechanism through which galaxies can become quenched. Here we present a novel AGN feedback model, which we have incorporated into the AREPO code, that evolves the black hole mass and spin as the accretion flow proceeds through a thin $α$-disc which we self-consistently couple to a Blandford-Znajek jet. We apply our model to the central region of a typical radio-loud Seyfert galaxy embedded in a hot circumgalactic medium (CGM). We find that jets launched into high pressure environments thermalise efficiently due to the formation of recollimation shocks and the vigorous instabilities that these shocks excite increase the efficiency of the mixing of CGM and jet material. The beams of more overpressured jets, however, are not as readily disrupted by instabilities so the majority of the momentum flux at the jet base is retained out to the head, where the jet terminates in a reverse shock. All jets entrain a significant amount of cold circumnuclear disc material which, while energetically insignificant, dominates the lobe mass together with the hot, entrained CGM material. The jet power evolves significantly due to effective self-regulation by the black hole, fed by secularly-driven, intermittent mass flows. The direction of jets launched directly into the circumnuclear disc changes considerably due to effective Bardeen-Petterson torquing. Interestingly, these jets obliterate the innermost regions of the disc and drive large-scale, multi-phase, turbulent, bipolar outflows.

description: An new method of calculating the energy spectrum of neutrinos and antineutrinos produced in the electron-positron annihilation processes in hot stellar plasma is presented. Detection of these neutrinos, produced copiously in the presupernova which is evolutionary advanced neutrino-cooled star, may serve in future as a trigger of pre-collapse early warning system. Also, observation of neutrinos will probe final stages of thermonuclear burning in the presupernova. The spectra obtained with the new method are compared to Monte Carlo simulations. To achieve high accuracy in the energy range of interest, determined by neutrino detector thresholds, differential cross-section for production of the antineutrino, previously unknown in an explicit form, is calculated as a function of energy in the plasma rest frame. Neutrino spectrum is obtained as a 3-dimensional integral, computed with the use of the Cuhre algorithm of at least 5% accuracy. Formulae for the mean neutrino energy and its dispersion are given as a combination of Fermi-Dirac integrals. Also, useful analytical approximations of the whole spectrum are shown.

description: This paper analyzes stochastic networks consisting of a set of finite capacity sites where different classes of individuals move according to some routing policy. The associated Markov jump processes are analyzed under a thermodynamic limit regime, that is, when the networks have some symmetry properties and when the number of nodes goes to infinity. An intriguing stability property is proved: under some conditions on the parameters, it is shown that, in the limit, several stable equilibrium points coexist for the empirical distribution. The key ingredient of the proof of this property is a dimension reduction achieved by the introduction of two energy functions and a convenient mapping of their local minima and saddle points. Networks with a unique equilibrium point are also presented.

description: Higher-order Laguerre-Gauss (LG) modes have previously been investigated as a candidate for reducing test-mass thermal noise in ground-based gravitational-wave detectors like Advanced LIGO. It has been shown however that LG modes' fragility against mirror surface figure imperfections limits their compatibility with the current state-of-the-art test masses. In this paper we explore the alternative of using higher-order Hermite-Gauss (HG) modes for thermal noise reduction, and show that with the deliberate addition of astigmatism they are orders of magnitude more robust against mirror surface distortions than LG modes of equivalent order. We present simulations of Advanced LIGO-like arm cavities with realistic mirror figures which can support HG$_{33}$ modes with average arm losses and contrast defects in a Fabry-Perot Michelson interferometer configuration which are well below the typical measured values in Advanced LIGO. This demonstrates that the mirror surface flatness errors will not be a limiting factor for the use of these modes in future gravitational-wave detectors.

description: Motivated by the recently experimental reported signatures of the tunable Mott insulating state and superconductivity in an ABC graphene trilayer superlattice, we investigate the charge compressibility, the spin correlation, and the superconducting instability within the Hubbard model on a three-layer honeycomb lattice. It is found that an antiferromagnetically ordered Mott insulator emerges beyond a critical $U_c$ at half-filling, and the electronic correlation drives a $d+id$ superconducting pairing to be dominant over other pairing patterns in a wide doped region. The effective pairing interaction with $d+id$ pairing symmetry is strongly enhanced with the increasing of on-site interaction, and suppressed as the interlayer coupling strength increases. Our intensive numerical results demonstrate that the insulating state and superconductivity in an ABC graphene trilayer are driven by strong electric correlation, and it may offer an attractive systems to explore rich correlated behaviors.

description: We show that the Szekeres system with cosmological constant admits a sufficient number of conservation laws, which allow to claim the integrability of the system. The main novelty in this investigation is that we find that the unique attractor of the Szekeres system is the isotropic inhomogeneous de Sitter (-like) universe, contrary to the original system in which the attractors describe Kantowski-Sachs (-like) spacetimes. We also study the existence of quantum corrections and the emergence of classicality by considering the linear and quadratic conserved quantities at the quantum level. We perform an analysis considering different approaches, involving the Bohmian quantum potential and a probability analysis. The result is that there are no quantum corrections for the quadratic integrals, while there exists a linear case for which we find quantum corrections.

Identifying the modes and mechanisms of action of transmission-blocking antimalarials against Plasmodium falciparum
Creators: name: Yahiya, Sabrina
Publisher: name: Imperial College London
Year: 2021

description: Phenotypic drug screening has transformed the antimalarial development pipeline, facilitating the discovery of compounds targeting unexplored parasite proteins at a drastically accelerated rate. Breaking the cycle of malaria transmission is crucial to eradication and centres around inhibition of the sexual stage gametocytes and gametes. Transmissible sexual stages represent a population bottleneck of the Plasmodium life-cycle which face little selective pressure and are hence a desirable target of drug intervention. Recently discovered in a phenotypic screen, the N-((4- hydroxychroman-4-yl)methyl)-sulphonamide (N-4HCS) compounds potently inhibit P. falciparum male gamete formation (microgametogenesis) in the mosquito. By combining study of the remarkable Plasmodium gametocyte cellular biology with medicinal chemistry and chemical proteomics, here we performed a detailed analysis of N-4HCS compound activity. Adhering to a traditional drug developmental pipeline, we first performed N- 4HCS hit-to-lead development and yielded compounds with activity in the nanomolar concentration range and favourable safety profiles. Furthermore, an N-4HCS photoaffinity probe was utilised in a proteome-wide photoaffinity labelling study, identifying the P. falciparum sexual stage-specific protein, Pfs16, as the compound target. Notably, the Cellular Thermal Shift Assay confirmed label-free specificity of N-4HCS compounds to Pfs16. Flow cytometry and phase-contrast, widefield- fluorescence and electron microscopy revealed compounds exclusively inhibited microgametogenesis, with a cellular phenotype consistent with published reports on the targeted gene disruption of Pfs16. We therefore present the 16kDa parasitophorous vacuole membrane protein, Pfs16, as a desirable antimalarial target and the N-4HCS compounds as potent candidates for future development. Additionally, a live-cell fluorescence microscopy workflow was devised to enable visualisation of microgametogenesis from the onset of activation through to exflagellation. Crucially, our imaging approach was applicable to drug discovery and is accessible to the malaria research community, thereby facilitating future study of transmission-blocking drug candidates. This thesis hence addressed the urgent requirement for novel antimalarial interventions, developing and aiding future discovery of transmission-blocking drugs.

description: The natural-heterostructure concept realized in delafossites highlights these layered oxides. While metallic, band- or Mott-insulating character may be associated with individual layers, inter-layer coupling still plays a decisive role. We review the correlated electronic structure of PdCoO$_2$, PdCrO$_2$ and AgCrO$_2$, showing that layer-entangled electronic states can deviate from standard classifications of interacting systems. This finding opens up possibilities for materials design in a subtle Mott-critical regime. Manipulated Hidden-Mott physics, correlation-induced semimetallicity, or Dirac/flat-band dispersions in a Mott background are emerging features. Together with achievements in the experimental preparation, this inaugurates an exciting research field in the arena of correlated materials.
Generation Mixing of Sneutrinos in Heavier Chargino Decay

description: The heavier chargino decay could yield two charged leptons of different generations, owing to generation mixing of sneutrinos. We discuss the possibility of producing $e$ and $μ$ through this process in near future collider experiments. The analyses are made systematically in the supersymmetric extension of the standard model without assuming a specific scenario for the mixing. Production of the heavier chargino is evaluated in $e^+e^-$ collisions. In the parameter region consistent with nonobservation of the radiative $μ$ decay, sizable parts lead to a detectable branching ratio for the generation-changing decay of the heavier chargino.

description: We study lepton flavor violation (LFV) associated with tau leptons in the framework of the two Higgs doublet model, in which LFV couplings are introduced as a deviation from Model II Yukawa interaction. Parameters of the model are constrained from experimental results and also from requirements of theoretical consistencies such as vacuum stability and perturbative unitarity. Current data for rare tau decays provide substantial upper limits on the LFV Yukawa couplings in the large $\tanβ$ region ($\tanβ\gtrsim 30 $), which are comparable with predictions in fundamental theories. Here $\tanβ$ is the ratio of vacuum expectation values of the two Higgs doublets. We show that a search for the LFV decays $ϕ^{0} \to τ^\pm μ^\mp$ $(τ^\pm e^\mp)$ of neutral Higgs bosons ($ϕ^{0} =h,H$ and $A$) at future collider experiments can be useful to further constrain the LFV couplings especially in the relatively small $\tanβ$ region ($\tanβ\lesssim 30 $), where rare tau decay data cannot give any strong limit.

description: We study 1D fermions with photoassociation or with a narrow Fano-Feshbach resonance described by the Boson-Fermion resonance model. Using thebosonization technique, we derive a low-energy Hamiltonian of the system. We show that at low energy, the order parameters for the Bose Condensation and fermion superfluidity become identical, while a spin gap and a gap against the formation of phase slips are formed. As a result of these gaps, charge density wave correlations decay exponentially in contrast with the phases where only bosons or only fermions are present. We find a Luther-Emery point where the phase slips and the spin excitations can be described in terms of pseudofermions. This allows us to provide closed form expressions of the density-density correlations and the spectral functions. The spectral functions of the fermions are gapped, whereas the spectral functions of the bosons remain gapless. The application of a magnetic field results in a loss of coherence between the bosons and the fermion and the disappearance of the gap. Changing the detuning has no effect on the gap until either the fermion or the boson density is reduced to zero. Finally, we discuss the formation of a Mott insulating state in a periodic potential. The relevance of our results for experiments with ultracold atomic gases subject to one-dimensional confinement is also discussed.

description: This paper uses laboratory experiments to test alternative water market institutions designed to protect third party interests. The institutions tested include taxing mechanisms that raise revenue to compensate affected third parties and a market in which third parties actively participate. The results indicate that there are some important trade-offs in selecting a policy option. Active third party participation in the market is likely to result in free riding that may erode some or all of the efficiency gains, and may introduce volatility into the market. Taxing transfers and compensating third parties offers a promising balance of efficiency, equity and market stability.

(Figs. 4 A-B)
 Holotype (ZMH 79807): shell height 2.0 mm, 1.8 mm width.
 Paratypes: 20 specimens from the type locality (ZMH 79808), 20 adult + numerous juvenile specimens in coll. Glöer, 15 specimens from the type locality (KSUZM 2014-103), 35 adult + numerous juvenile specimens in coll. Gürlek.
 Locus typicus: Turkey, Kahramanmaraş Province, spring Çataloluk, 37 ° 27 ’ 2.11'' N, 36 ° 45 ’ 33.62'' E.
 Etymology: Named after the province and city (Kahramanmaraş) where the new species was collected. Description.
 Shell. The horn-colored shell is conical with 4.5-5 whorls which are slightly convex with a deep suture (Fig. 4A). The whorls are regularly fast growing with a prominent body whorl. The umbilicus is closed. The aperture is oval. The shells are 2.2-2.3 mm in height and 1.8 mm broad.
 Body. The mantel as well as head and snout are black, eye spots are visible. The operculum is light orange. The penis is triangular without any outgrowth, very broad at the base and acute at the distal end (Fig. 4B).
 Differentiating features: The conical shape of the shell makes the new species close to P. goksunensis n. sp. However, the latter species can easily be distingushed from P. marashi n. sp. by the larger shell dimensions (4.5 mm vs. 2.3 mm in P. marashi n. sp.).
 Habitat: Spring, with a well developed vegetation and a muddy bottom.

description: We have fabricated an array of subgap kinetic inductance detectors (SKIDs) made of granular aluminum ($T_c\sim$2~K) sensitive in the 80-90 GHz frequency band and operating at 300~mK. We measure a noise equivalent power of $1.3\times10^{-16}$~W/Hz$^{0.5}$ on average and $2.6\times10^{-17}$~W/Hz$^{0.5}$ at best, for an illuminating power of 50~fW per pixel. Even though the circuit design of SKIDs is identical to that of the kinetic inductance detectors (KIDs), the SKIDs operating principle is based on their sensitivity to subgap excitations. This detection scheme is advantageous because it avoids having to lower the operating temperature proportionally to the lowest detectable frequency. The SKIDs presented here are intrinsically selecting the 80-90 GHz frequency band, well below the superconducting spectral gap of the film, at approximately 180 GHz.

description: Recent surveys of wheat importers indicate that countries that import wheat via a state-trading enterprise (STE) are less sensitive to quality issues in import decision-making than countries that import wheat through private traders. This study examines conceptually and empirically the impact of the deregulation of wheat imports on the quality and source of wheat imports.

description: The hypothalamus-pituitary-thyroid (HPT) axis regulates energy balance through the pleiotropic action of thyroid hormones. HPT basal activity and stimulation by cold or voluntary exercise are repressed by previous chronic stress in adults. As maternal separation (MS) modifies HPT basal activity we now studied the response of the axis to energy demands and analyzed possible epigenetic changes on Trh promoter. Non-handled (NH) or MS male Wistar rats were cold exposed for 1h at adulthood that stimulated Trh expression in the hypothalamic paraventricular nucleus (PVN) and serum TSH concentration only in NH rats. MS male rats responded to two weeks of running-wheel exercise similarly to NH-, increased Trh expression and decreased fat mass and leptin serum-concentration. Although NH-females ran more than MS and much more than males, exercise decreased body weight and reduced fat mass only in NH-rats with no change on any parameter of HPT axis but increased Pomc expression in arcuate-nucleus NH-, whereas Npy in MS-females. Overall methylation pattern of PVN Trh gene promoter was similar in NH-males or -females; MS modified methylation of specific CpG sites, a thyroid-hormone receptor (THR) binding site present after the initiation site was hypomethylated in MS-males, whereas in MS-females the THR binding-site of the proximal promoter (site 4) and two sites in the first intron were hypermethylated. Our studies showed that, in a sex dimorphic manner, MS blunted the responses of HPT axis to energy demands in adult animals and caused methylation changes on Trh promoter that could alter T3 feedback.

description: This paper uses laboratory experiments to test the theoretical observations that both the violations of competitive risk-neutral firms and the marginal effectiveness of increased enforcement across firms are independent of differences in their abatement costs and their initial allocations of permits. This conclusion has important implications for enforcing emissions trading programs because it suggests that regulators have no justification for targeting their enforcement effort based on firm-level characteristics. Consistent with the theory, we find that subjects' violations were independent of parametric differences in their abatement costs. However, those subjects that were predicted to buy permits tended to have higher violation levels than those who were predicted to sell permits. Despite this, we find no statistically significant evidence that the marginal effectiveness of enforcement depends on any firm-specific characteristic. We also examine the determinants of compliance behavior under fixed emissions standards. As expected, we find significant differences between compliance behavior under fixed standards and emissions trading programs.

Nonsingular bouncing cosmology in general relativity: physical analysis of the spacetime defect

description: In this paper, we describe physical effects occurring in the regularized Robertson-Walker spacetime which can reveal the presence of the defect. Our analysis is based on two main physical quantities: the compressive forces acting on (human) observers and the energy possessed by massive particles and photons during their dynamical evolution. In Sec. 3, we claim that with a characteristic length scale of the order of the Planck length compressive forces become so intense near the defect that no (human) observer is able to cross it. In Sec. 4, we show that the energy exhibits an unusual character over a small time interval around the bounce contrasting with the behaviour in the standard cosmology picture. We conclude the paper with some considerations and open problems related to our results.

The X-ray emission lines in GRB afterglows: the evidence for the two-component jet model

description: Recently, X-ray emission lines have been observed in X-ray afterglows of several $γ$-ray bursts. It is a major breakthrough for understanding the nature of the progenitors. It is proposed that the X-ray emission lines can be well explained by the Geometry-Dominated models, but in these models the illuminating angle is much larger than that of the collimated jet of the $γ$-ray bursts(GRBs). For GRB 011211, we obtain the illuminating angle is about $θ\sim45^{\circ}$, while the angle of GRB jet is only $3.6^{\circ}$, so we propose that the outflow of the GRBs with emission lines should have two distinct components. The wide component illuminates the reprocessing material, and produces the emission lines, while the narrow one produces the $γ$-ray bursts. The observations show that the energy for producing the emission lines is higher than that of the GRBs. In this case, when the wide component dominates the afterglows, a bump will appear in the GRBs afterglows. For GRB 011211, the emergence time of the bump is less than 0.05 days after the GRB, it is obviously too early for the observation to catch it. With the presence of the X-ray emission lines there should also be a bright emission component between the UV and the soft X-rays. These features can be tested by the $Swift$ satellite in the near future.
