description: The $Δ(1232) \to γ^\ast N$ magnetic dipole form factor ($G_M^\ast$) is described here within a new covariant model that combines the valence quark core together with the pion cloud contributions. The pion cloud term is parameterized by two terms: one connected to the pion electromagnetic form factor, the other to the photon interaction with intermediate baryon states. The model can be used in studies of pp and heavy ion collisions. In the timelike region this new model improves the results obtained with a constant form factor model fixed at its value at zero momentum transfer. At the same time, and in contrast to the Iachello model, this new model predicts a peak for the transition form factor at the expected position, i.e. at the $ρ$ mass pole. We calculate the decay of the $Δ\to γN$ transition, the Dalitz decay ($Δ\to e^+ e^- N$), and the $Δ$ mass distribution function. The impact of the model on dilepton spectra in pp collisions is also discussed.

Efficient arithmetic on elliptic curves in characteristic 2

Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: We present normal forms for elliptic curves over a field of characteristic $2$ analogous to Edwards normal form, and determine bases of addition laws, which provide strikingly simple expressions for the group law. We deduce efficient algorithms for point addition and scalar multiplication on these forms. The resulting algorithms apply to any elliptic curve over a field of characteristic $2$ with a $4$-torsion point, via an isomorphism with one of the normal forms. We deduce algorithms for duplication in time $2M + 5S + 2m_c$ and for addition of points in time $7M + 2S$, where $M$ is the cost of multiplication, $S$ the cost of squaring, and $m_c$ the cost of multiplication by a constant. By a study of the Kummer curves $\mathcal{K} = E/\{[\pm1]\}$, we develop an algorithm for scalar multiplication with point recovery which computes the multiple of a point $P$ with $4M + 4S + 2m_c + m_t$ per bit where $m_t$ is multiplication by a constant that depends on $P$.

description: Different injection levels make the comparison of BO Regeneration kinetics in different Si wafers or
solar cells difficult, e.g., when samples made of different materials featuring different background lifetime levels are to
be compared. A correction factor is presented that is able to compensate for these differences in injection level during
Regeneration. This is used to investigate the influence of metallic impurities, interstitial oxygen and different dopants on
BO Regeneration kinetics. It is found that a POCl3 gettering step only affects Regeneration if the overall H concentration
within the wafer is low. Interstitial oxygen is found to be less detrimental to Regeneration than assumed previously. The
influence of different dopants is shown in a process leading to a stable regenerated lifetime, and the measured
Regeneration rates can be compared because of the applied injection correction. A numerical fit optimization method is
presented to separate the influence of the different dopants. It is shown that net doping concentration p0 is not relevant for
BO Regeneration whereas B as well as Ga slow down the Regeneration process. An explanation within the H-model of
BO Regeneration is given.

description: We report the operation of a cold-atom inertial sensor in a joint interrogation scheme, where we simultaneously prepare a cold-atom source and operate an atom interferometer in order to eliminate dead times. Noise aliasing and dead times are consequences of the sequential operation which is intrinsic to cold-atom atom interferometers. Both phenomena have deleterious effects on the performance of these sensors. We show that our continuous operation improves the short-term sensitivity of atom interferometers, by demonstrating a record rotation sensitivity of $100$ nrad.s$^{-1}/\sqrt{\rm Hz}$ in a cold-atom gyroscope of $11$ cm$^2$ Sagnac area. We also demonstrate a rotation stability of $1$ nrad.s$^{-1}$ after $10^4$ s of integration, improving previous results by an order of magnitude. We expect that the continuous operation will allow cold-atom inertial sensors with long interrogation time to reach their full sensitivity, determined by the quantum noise limit.

description: Batches of Al-BSF and PERC cells (including both PERD and PERL rear cells) have been produced on
Suntech’s Pluto production line. On the front side, laser formed anchor points of varying densities have been
superimposed on laser-doped fingers for greatly improved adhesion of plated contacts. Even on a high voltage PERL
structure, 10% coverage of anchor points can result in negligible efficiency loss when coupled with deep laser doped
fingers, and only 0.1% absolute loss compared to highest efficiency PERC structure with no anchor points;
apparently a small loss compared to the improvements in plating adhesion and reliability.

description: Bifacial solar cell n-PERT concept involves boron and phosphorus doped regions requiring both proper
surface passivation. In order to reduce n-PERT technology related €/W, one way considered is to simplify the cell
process-flow. In order to do so, we developed passivating/ anti-reflective/ doping SiOxNy:B and SiNx:P layers. The
co-anneal of these multifunctional layers allows for emitter & BSF simultaneous formation, subsequent doped
regions passivation and provides in the same time good optical properties. We present our ultimately simplified
“SOLENNA(3)” technology, involving only 7 processing steps. Furthermore, the influence of the wafers initial
properties (P and Oi concentrations, Thermal History Index) on the performances of the SOLENNA(3) cells is
studied. By further optimization of our front SiOxNy:B, large area (239cm²) LID-free n-PERT devices could be
fabricated with a PV conversion efficiency of 20.3%.

description: Due to budgetary constraints and the high level of training required, digital forensic analysts are in short supply in police forces the world over. This inevitably leads to a prolonged time taken between an investigator sending the digital evidence for analysis and receiving the analytical report back. In an attempt to expedite this procedure, various process models have been created to place the forensic analyst in the field conducting a triage of the digital evidence. By conducting triage in the field, an investigator is able to act upon pertinent information quicker, while waiting on the full report. The work presented as part of this paper focuses on the training of front-line personnel in the field triage process, without the need of a forensic analyst attending the scene. The premise has been successfully implemented within regular/non-digital forensics, i.e., crime scene investigation. In that field, front-line members have been trained in specific tasks to supplement the trained specialists. The concept of front-line members conducting triage of digital evidence in the field is achieved through the development of a new process model providing guidance to these members. To prove the model's viability, an implementation of this new process model is presented and evaluated. The results outlined demonstrate how a tiered response involving digital evidence specialists and non-specialists can better deal with the increasing number of investigations involving digital evidence.

description: In this study, high speed dispensing with a novel 6” dispensing print head is applied to different screen printing
pastes. The novel print head features a homogeneous distribution of Ag-paste from an inlet supply with a diameter of Din = 2mm to an outlet slot with a width of ws = 160 mm. A first printing test followed by geometrical characterization of the dispensed contacts revealed a distribution of the contact finger width of wf = 35±1 μm across the whole wafer (156x156mm²) which demonstrates highest precision of the device. The print head is directly integrated in an inline feasible dispensing platform, developed by ASYS GmbH. Respective nozzle plates can be customized to any desired front side grid regarding nozzle diameter, nozzle pitch and the total number of nozzles n. In the actual version, the print head uses two strokes to print two adjacent contact fingers using 50 nozzles while moving up and down at a speed of up to vy = 700mm/s. In a first solar cell test sequence with the new 6“ print head, a
maximum cell efficiency of  n = 21.2% on industrially preprocessed Cz-PERC samples was reached which demonstrates a successful launching of the print head. A follow up experiment with an industrial reference paste demonstrated similar results on the same material. Here, for the first time, a nozzle opening of only   35μ allowed for a reduction of the wet paste
consumption down to mwet,Ag  50mg for the contact grid (N = 100) which is a reduction of m/m  15% compared to
screen printed references. At the same time, more homogeneous contact fingers allow for a reduced grid resistance of RGrid/RGrid = -10%.

description: In the paper [Eur. J. of Appl. Math. \textbf{20}, (2009) 269--287] by da Costa et al. the twist-Fréedericksz transition in a nematic liquid crystal one-dimensional cell of lenght $L$ was studied imposing an antisymmetric net twist Dirichlet condition at the cell boundaries. In the present paper we extend that study to the more general case of net twist Dirichlet conditions without any kind of symmetry restrictions. We use phase-plane analysis tools and appropriately defined time-maps to obtain the bifurcation diagrams of the model when $L$ is the bifurcation parameter, and related these diagrams with the one in the symmetric situation. The stability of the bifurcating solutions is investigated by applying the method of Kenjiro Maginu [J. Math. Anal. Appl. \textbf{63}, (1978) 224--243].

description: We fabricate n-type rear emitter cells with a boron silicate glass (BSG) layer deposited by means of
plasma-enhanced chemical vapor deposition (PECVD). The multi-functional stack consisting of the BSG layer and a
PECVD silicon nitride (SiNz) capping layer acts both as a boron diffusion source and as the rear side passivation
achieving saturation current densities of J0=40 fA/cm². For solar cell fabrication, the rear emitter is diffused from the
BSG/SiNz stack while the front surface field (FSF) is diffused from POCl3 gas in a co-diffusion process. We present a
novel n+ n p+ solar cell concept and name it BiCoRE (Bifacial Co-diffused Rear Emitter) cell that applies a screenprinted
Al grid on the rear side for bifaciality. The process flow and complexity of the BiCoRE cells are very similar
to industrial Passivated Emitter and Rear Cells (PERC). The BiCoRE cells processed on the very first batch
demonstrate conversion efficiencies up to h=20.6% when illuminated from the front side, up to 16.1% rear-side
efficiency and a bifaciality of 78%.
Topological physics in one-dimensional chains of metallic nanoparticles
Creators: name: Pocock, Simon
Publisher: name: Imperial College London
Year: 2019

description: The focus of this thesis is the study of a chain of metal nanoparticles with alternating spacing, an artistic impression of which is given in figure 0.1. At first glance, this seems like a fairly simple system but, in reality, its study is a dive into two of the most exciting fields in modern condensed matter physics: topological insulators and light-matter interactions. In fact, the properties of light lead us to consider some of the most pressing questions in the field of topological insulators today. The first half of the thesis covers all of the theory needed to understand the original work presented in the second half. The first chapter includes a historical review of topological insulators, an introduction to some of the fundamental concepts in the field, and an overview of photonic and non-Hermitian topological insulators. This is followed, in the second chapter, by a detailed discussion of the famous Su-Schrieffer-Heeger model and important results from the theory of scattering of light by nanoparticles. In the remaining chapters, which make up the second half of the thesis, we present models for the chain which take into account the nature of light and result in a wealth of interesting topological physics. The polarisation of light affects the topology dramatically, with stable topology and protected plasmonic edge states in one polarisation and the complete breakdown of bulk-edge correspondence in another. The absorption of light and its phase properties force the system to be non-Hermitian. This, combined with the long range coupling of the metal nanoparticles, leads to unexpected topological phase transitions. These results are elaborated on in the following work, along with extinction cross sections of the chain, a non-Hermitian next-nearest-neighbour Su-Schrieffer-Heeger model extension, and a minimal model for the non-Hermitian phase transitions.

description: This work reports on state-of-the-art silicon material characterization by calibrated photoluminescence imaging (PLI). PL imaging techniques allow for a characterization of a large variety of material properties, ranging from bulk and surface recombination properties of bare silicon ingots, to crystal structure, dopant concentration and bulk lifetime of silicon wafers up to material limiting impurities. In combination with solar cell simulations, injec-tion-dependent PLI of processed wafers provides a method for determining the material’s efficiency potential. In this contribution, we present two methods for imaging the concentration of interstitial iron at passivated silicon slices and at unpassivated silicon ingots. The latter is achieved by our latest progress in PL-based charge carrier bulk lifetime measurements with highest sensitivity, giving access to the bulk recombination properties of the ingot. Additionally, we present an improved analysis of specific loss mechanisms in silicon based on de-smeared injection-dependent life-time images of processed wafers, which is demonstrated on the example of the bulk-related efficiency limitations in high-performance multicrystalline silicon. This latest progress rounds off the established techniques, enhancing the potential of PL based imaging techniques for a comprehensive assessment of silicon material quality, from limitations in bare silicon ingots to efficiency loss mechanisms in processed samples.

description: Abstract—Beyond 5G networks demand the transition from automated to autonomous network management to decrease human intervention and improve the end-to-end network efficiency. ETSI Zero-Touch Network and Service Management (ZSM) group proposes a service-based architecture to achieve this end. One integral element of such architecture is the Integration Fabric (IF). This demonstration proposes and shows an architecture for the IF element, which enables inter-administrative domain orchestration operations in multiple management domains under the control of different service providers thought up for crossborder vehicular scenarios. These management domains are constituted by a standard ETSI NFV-based Management and Orchestration stack, hence we also demonstrate integration of original NFV work with those proposed by the ZSM architecture.

description: The current cost pressure within the photovoltaic industry requires innovative approaches to increase productivity and reduce production costs. The use of highly productive rotational printing methods offers the poten-tial to increase the throughput of the cost-intensive metallization process by the factor 2 to 3. Within this work, we present two innovative rotational printing technologies – flexographic printing and rotary screen printing – for the front side metallization of Silicon solar cells. We show that both technologies can realize contact fingers with a lateral finger resistance RL well below 10 /cm in one printing step which is sufficient for busbarless solar cells with multi-wire interconnection. For flexographic printing, we found a strong impact of the anilox roller properties on geometry and lateral resistance of the contact fingers. With respect to flexographic printing, narrow contact fingers with a mean lateral resistance down to RL = 5.8 /cm could be printed in a single printing step using a large dip volume of VD = 16.5 cm³/cm². For rotary screen printing, an even lower lateral finger resistance down to RL = 1.1 /cm could be achieved. Yet, further process optimization is required to reduce paste spreading and thus the printed finger width.

description: We apply scaling and the theory of the fundamental limits of the second-order molecular susceptibility to identify material classes with ultralarge nonlinear-optical response. Size effects are removed by normalizing all nonlinearities to get intrinsic values so that the scaling behavior of a series of molecular homologues can be determined. Several new figures of merit are proposed that quantify the desirable properties for molecules that can be designed by adding a sequence of repeat units, and used in the assessment of the data. Three molecular classes are found. They are characterized by sub-scaling, nominal scaling, or super-scaling. Super-scaling homologues most efficiently take advantage of increased size. We apply our approach to data currently available in the literature to identify the best super-scaling molecular paradigms with the aim of identifying desirable traits of new materials.

paper. The cell features a rear surface field formed by phosphorous implant and a fully diffused BBr3 front emitter with

dielectrics on front-side with a front metallization based on Ni/Cu forward bias plating and sintered metal paste for the
rear contacting electrode. The performance results show better cell’s efficiency in comparison to common double sides
sintered metal paste electrodes. Large-area (238.9 cm2) silicon solar cells manufactured on 170 μm thick, 3Ω -

Maximal connected subgroups of algebraic k-groups

Publisher: name: Imperial College London
Year: 2019

description: Let $k$ be any field. Let $G$ be a connected reductive algebraic $k$-group. Associated to $G$ is an invariant that is called the index of $G$. For the cases where $G$ is absolutely simple, Tits classified all possibilities for the index of $G$. Let $H$ be a connected reductive $k$-subgroup of maximal rank in $G$. We introduce an invariant of the pair $HG_1>...>G_t=1$ where each $G_i$ is a maximal connected real subgroup of $G_{i-1}$. The maximal (respectively, minimal) length of such an unrefinable chain is called the length (respectively, depth) of $G$. We give a precise formula for the length of $G$, which generalises results of Burness, Liebeck and Shalev on complex algebraic groups and also on compact Lie groups. If $G$ is simple then we bound the depth of $G$ above and below, and in many cases we compute the exact value. In particular, the depth of any simple $G$ is at most $9$.

description: Water is a very abundant molecule in star-forming regions. Its deuterium fractionation is an important tool for understanding its formation and evolution during the star and planet formation processes. While the HDO/H$_2$O ratio has been determined toward several Class 0 protostars and comets, the number of studies toward Class I protostars is limited. We aim to study the water deuteration toward the Class I binary protostar L1551 IRS5 and to investigate the effect of evolutionary stage and environment on variations in the water D/H ratio. Observations were made using the NOEMA interferometer. The HDO 3$_{1,2}$-2$_{2,1}$ transition at 225.9 GHz and the H$_2^{18}$O 3$_{1,3}$-2$_{2,0}$ transition at 203.4 GHz were covered with a spatial resolution of 0.5'' $\times$ 0.8'', while the HDO 4$_{2,2}$-4$_{2,3}$ transition at 143.7 GHz was observed with a resolution of 2.0'' $\times$ 2.5''. We used both LTE and non-LTE models. The three transitions are detected. The line profiles display two peaks, one at $\sim$6 km s$^{-1}$ and one at $\sim$9 km s$^{-1}$. We derive an HDO/H$_2$O ratio of (2.1 $\pm$ 0.8) $\times$ 10$^{-3}$ for the redshifted component and a lower limit of $>$ 0.3 $\times$ 10$^{-3}$ for the blueshifted component due to the blending with the redshifted CH$_3$OCH$_3$ emission. The HDO/H$_2$O in L1551 IRS5 is similar to the ratios in isolated Class 0 sources and to the Class I V883 Ori, while it is significantly higher than in the clustered Class 0 sources and the comets. This suggests that the chemistry of protostars in low source densities clouds share more similarities with the isolated sources than the protostars of very dense clusters. If Class 0 protostars with few sources around and isolated Class 0 objects are comparable in the HDO/H$_2$O ratio, it would mean that there is little water reprocessing from the Class 0 to Class I protostellar stage.

description: A method for residual stress measurements on large silicon samples is described. It combines strain gauge measurements in combination with the dissection of the gauge area. We report about tests and our experience with the technique and apply it on flat boards cut out of large ingots. Measurements on several boards from the same ingot are used to estimate the accuracy and the source of possible errors. The measurements are accompanied by thermal and thermomechanical simulation. Comparing the measurement results with the prediction of the simulation the accuracy of both measurement and simulation model can be assessed.

description: High lifetime, process-tolerant wafers and low-recombination, passivated contacts for both electrons
and holes, can enable high efficiency and industrially-relevant Si PV with n-type Cz material. We develop and apply
an O-cluster dissolution treatment to make n-Cz wafers immune to thermal processing, maintaining high lifetime >3
ms. For low-recombination contacts, we advance tunneling passivated contacts (TPCs) based on a thin tunneling SiO2
and doped n- or p-type poly-Si. n-type TPC that are in-situ P-doped during PECVD growth reach implied Voc = 735
mV, while the performance of the corresponding p-type B-doped TPC is at 700 mV. We further develop ionimplantation
doping to facilitate patterning of n- and p-type TPCs for interdigitated back passivated contact cells [1];
implied Voc of 730 and 694 mV are achieved for ion-implanted n- and p-type TPCs, respectively. Finally, we produce
an IBC cell with passivated contacts with Voc = 693 mV, Jsc = 36.4 mA/cm2, FF = 69.1% and efficiency of 17.4%.

description: In the single fluid, nonrelativistic, ideal-Magnetohydrodynamic (MHD) plasma description magnetic field lines play a fundamental role by defining dynamically preserved "magnetic connections" between plasma elements. Here we show how the concept of magnetic connection needs to be generalized in the case of a relativistic MHD description where we require covariance under arbitrary Lorentz transformations. This is performed by defining 2-D {\it magnetic connection hypersurfaces} in the 4-D Minkowski space. This generalization accounts for the loss of simultaneity between spatially separated events in different frames and is expected to provide a powerful insight into the 4-D geometry of electromagnetic fields when ${\bf E} \cdot {\bf B} = 0$.

description: In this work, a route towards high efficiency n-type solar cells with a Passivated Emitter and Rear Totally
Diffused (PERT) structure done by a combination of characterization and modeling is presented. Low cost industrial
processes such as tube diffusion and plating have been used for the fabrication. Optimization result on emitter profile
shows that shallower junction depth emitter with 93 ohm/sq sheet resistance brings a 0.23% absolute efficiency gain. A
champion efficiency of 22.40% has been achieved on 6 inch CZ wafers after further optimization of front finger and rear
pitch. The semicondutor device simulation software Sentaurus is used to reveal that injection-dependent lifetime due to
shallow defects enhance the fill factor in n-type solar cells.

transmission chains

description: In order to assess C. difficile/AMR dissemination between humans, animals and the environment, studies were conducted on samples from 4 countries (2 HOALs Portugal, Austria, 1 agricultural facility Estonia, single compartments Ireland). The results obtained allowed to perform a classification of pig farm compartments according to their role in the epidemiology of C. difficile, which was identified in all the following ecosystems: pig barn (faeces), manure (pig), wild animals, soil (agricultural fields), river water, ground water, wastewater treatment plant and air. In addition, in each HOAL, a different toxigenic C. difficile RT (RT033, RT078 and RT049, respectively) was dominant, reflecting well-established transmission chains and a resilient source. Overall, the results obtained from the 3 HOALs/agricultural facility showing the presence of dominant clones in compartments associated with the pig production unit suggest a transmission chain involving these animals. They contribute to unveiling the role played by animal and environmental reservoirs within the C. difficile epidemiology.

description: Black silicon (b-Si) is of particular interest for the PV industry since it can significantly reduce reflection losses. A promising preparation method of b-Si surface textures is maskless plasma etching. However, the detailed mechanism of maskless plasma texturing in an SF6/O2 atmosphere is still unclear. In particular, the self-masking process is not well understood. For that reason, the change of the elemental composition of the Si surface caused by the plasma process is investigated by X-ray photoelectron spectroscopy (XPS) to discuss the formation of the self-masking layer. Evidence of a fluorine containing oxide layer was found on the surface of b-Si for the first time. Furthermore, it is shown that fluorine desorbs quickly out of the top layer under ambient air, which makes it challenging to characterize the self-masking layer. These results are an important contribution towards the understanding of the formation of plasma etched b-Si and the resulting oxide layer.
A rare example of low surface-brightness radio lobes in a gas-rich early-type galaxy: the story of NGC 3998

description: We study the nearby lenticular galaxy NGC 3998. This galaxy is known to host a low-power radio AGN with a kpc-size one-sided jet and a large, nearly polar HI disc. It is therefore a good system to study to understand the relation between the availability of cold-gas and the triggering of AGNs in galaxies. Our new WSRT data reveal two faint, S-shaped radio lobes extending out to $\sim$10 kpc from the galaxy centre. Remarkably, we find that the inner HI disc warps back towards the stellar mid-plane in a way that mirrors the warping of the radio lobes. We suggest that the polar HI disc was accreted through a minor merger, and that the torques causing it to warp in the inner regions are also responsible for feeding the AGN. The "S" shape of the radio lobes would then be due to the radio jets adapting to the changing angular momentum of the accreted gas. The extended radio jets are likely poorly collimated, which would explain their quick fading and, therefore, their rarity in galaxies similar to NGC 3998. The fuelling of the central super-massive black hole is likely occurring via "discrete events", suggested by the observed variability of the radio core and the extremely high core dominance, which we attribute to the formation and ejection of a new jet resulting from a recent fuelling event.

description: In this paper we present the first results obtained at CEA-INES for the integration of thin and ultra-thin
silicon wafers in the current silicon heterojunction (SHJ) LabFab Pilot Line production flow. Impact of the cell
thickness reduction on final device characteristics is first detailed. Then overall compatibility of such wafers with
current production constraints and actual equipment’s configuration is analyzed, identifying main breakage and
throughput issues. Finally, improvement paths are proposed to enhance both efficiencies and reliability on the overall
cell fabrication flow demonstrating also the potential compatibility of current SHJ production line for wafers as thin
as 80μm.

description: The spin fluctuations of electron and hole doped self-assembled quantum dot ensembles are measured optically in the low-intensity limit of a probe laser in absence and presence of longitudinal or transverse static magnetic fields. The experimental results are modeled by two complementary approaches based either on semiclassical or quantum mechanical descriptions. This allows us to characterize the hyperfine interaction of electron and hole spins with the surrounding bath of nuclei on time scales covering several orders of magnitude. Our results demonstrate (i) the intrinsic precession of the electron spin fluctuations around the effective nuclear Overhauser field caused by the host lattice nuclear spins, (ii) the comparably long time scales for electron and hole spin decoherence, as well as (iii) the dramatic enhancement of the spin lifetimes induced by a longitudinal magnetic field due to the decoupling of nuclear and charge carrier spins.

A mechanism for fast radio bursts

description: Fast radio bursts are mysterious transient sources likely located at cosmological distances. The derived brightness temperatures exceed by many orders of magnitude the self-absorption limit of incoherent synchrotron radiation, implying the operation of a coherent emission process. We propose a radiation mechanism for fast radio bursts where the emission arises from collisionless Bremsstrahlung in strong plasma turbulence excited by relativistic electron beams. We discuss possible astrophysical scenarios in which this process might operate. The emitting region is a turbulent plasma hit by a relativistic jet, where Langmuir plasma waves produce a concentration of intense electrostatic soliton-like regions (cavitons). The resulting radiation is coherent and, under some physical conditions, can be polarised and have a power-law distribution in energy. We obtain radio luminosities in agreement with the inferred values for fast radio bursts. The timescale of the radio flare in some cases can be extremely fast, of the order of $10^{-3}$ s. The mechanism we present here can explain the main features of fast radio bursts and is plausible in different astrophysical sources, such as gamma-ray bursts and some Active Galactic Nuclei.
