description: Infrared imaging properties of dusty winds around late-type stars are investigated in detail, employing a self-consistent model that couples the equations of motion and radiative transfer. Because of general scaling properties, the angular profiles of surface brightness are self-similar. In any given star, the profile shape is determined essentially by overall optical depth at each wavelength and it is self-similarly scaled by the size of the dust condensation zone. We find that the mid-IR is the best wavelength range to measure directly the angular size of this zone, and from {\it IRAS} data we identify the 15 best candidates for such future observations. We also show that the visibility function at short wavelengths ($\la$ 2 \mic) directly determines the scattering optical depth, and produce theoretical visibility curves for various characteristic wavelengths and the entire parameter range relevant to late-type stars. The infrared emission should display time variability because of cyclical changes in overall optical depth, reflecting luminosity-induced movement of the dust condensation point. Calculations of the wavelength dependence of photometric amplitudes and time variability of envelope sizes are in agreement with observations; envelopes are bigger and bluer at maximum light.

description: Protoplanetary disks can exhibit asymmetric temperature variations due to phenomena such as shadows cast by the inner disk or localized heating by young planets. We investigate the disk features induced by these asymmetric temperature variations. We find that spirals are initially excited, then break into two and reconnect to form rings. By carrying out linear analyses, we first study the spiral launching mechanism, and find that the effects of azimuthal temperature variations share similarities with effects of external potentials. Specifically, rotating temperature variations launch steady spiral structures at Lindblad resonances, which corotate with the temperature patterns. When the cooling time exceeds the orbital period, these spiral structures are significantly weakened, and a checkerboard pattern may appear. A temperature variation of about 10\% can induce spirals with order unity density perturbations, comparable to those generated by a thermal mass planet. We then study ring formation and find it is related to the coupling between azimuthal temperature variations and spirals outside the resonances. Such coupling leads to a radially varying angular momentum flux, which produces anomalous wave-driven accretion and forms dense rings separated by the wavelength of the waves. Finally, we speculate that spirals induced by temperature variations may contribute to disk accretion through non-linear wave steepening and dissipation. Overall, considering that irradiation determines the temperature structure of protoplanetary disks, the change of irradiation both spatially or/and temporarily may produce observable effects in protoplanetary disks, especially spirals and rings in outer disks beyond tens of AU.

description: We report the discovery of the first likely black hole in a non-interacting binary system with a field red giant. By combining radial velocity measurements from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) with photometric variability data from the All-Sky Automated Survey for Supernovae (ASAS-SN), we identified the bright rapidly-rotating giant 2MASS J05215658+4359220 as a binary system with a massive unseen companion. Subsequent radial velocity measurements reveal a system with an orbital period of 83 days and near-zero eccentricity. The photometric variability period of the giant is consistent with the orbital period, indicative of star spots and tidal synchronization. Constraints on the giant's mass and radius from its luminosity, surface gravity, and temperature imply an unseen companion with mass of $3.3^{+2.8}_{-0.7}$ M$_\odot$, indicating a low-mass black hole or an exceedingly massive neutron star. Measurement of the astrometric binary motion by {\it Gaia} will further characterize the system. This discovery demonstrates the potential of massive spectroscopic surveys like APOGEE and all-sky, high-cadence photometric surveys like ASAS-SN to revolutionize our understanding of the compact object mass function, and to test theories of binary star evolution and the supernova mechanism.

description: The progress achieved in recent years in the biomedical field justifies the objective evaluation of new techniques and materials obtained by using silver in different forms as metallic silver, silver salts, and nanoparticles. Thus, the antibacterial, antiviral, antifungal, antioxidant, and anti-inflammatory activity of silver nanoparticles confers to newly obtained materials characteristics that make them ideal candidates in a wide spectrum of applications. Hydroxypropyl methylcellulose is routinely used for the controlled release of medicine thanks to its slow dissolution in water and could be used as a matrix for the controlled release of silver nanoparticles, if a method to produce such a material without the need of other reactants was developed. We proposed such a method in a photochemical reduction of AgNO3 in hydroxypropyl methylcellulose solutions by the illumination of the mixture with the UV irradiation.

description: This paper surveys the different approaches to the analysis of international trade and economic development. Recent Neoclassical trade theory, the conjectures of Marx, the Neo-Marxist theories of trade and underdevelopment, and the structuralist (North-South) literature is examined. The different perspectives all seem to indicate that the gains-from trade is a potential concept. Its realization and distribution depend largely on the structure of markets, the nature of policies and the character of state power.

description: Instrumentalists and specifically percussionists have been found to develop musculoskeletal disorders (MSDs) due to the nature of their work. This study aimed to assess the MSD risk factors associated with playing the steel pan, which was invented in Trinidad and Tobago in the 20th century. A sample of 13 pannists and 13 non-pannists completed a modified Nordic Musculoskeletal Questionnaire and data analysis included multiple correlations, a Student’s t-test, the Moore-Garg Strain Index and a calculation of compressive force at the L5/S1 vertebrae. The prevalence of pain was found to be greater among the pannists; a Strain Index of 22.78 was calculated and the compressive force determined to be 4507.8N which indicated that pannists have a high risk of developing MSDs of the upper limb and lower back. The risk factors identified for the development of MSDs were similar to those of previous studies.

description: The Temperate Plains ecoregion of Indiana has experienced significant agricultural development since the 19th century, which has left streams vulnerable to impacts such as sedimentation and nutrient accumulation. This thesis describes first the accuracy of the USDA Cropland Data Layer (CDL) in land cover change, and second, the relationships between agricultural and forested land covers and stream biological integrity. I first employed the CDL to review land cover change, particularly relating to agriculture and forest, for the area of interest between 2010 and 2020. I determined that the CDL improved in accuracy for the area of interest in the chosen timeframe for non-agricultural and non-forest land cover. I concluded that the CDL was best used as a supplement to primary-source land cover measures. Next, I calculated the fish Index of Biotic Integrity (IBI) scores for 20 sampled agricultural and forested streams in North-Central Indiana. I also assessed the stream habitats at all sites using the Qualitative Habitat Evaluation Index (QHEI) and percent cultivated crops in drainage basin areas for all streams. Forested streams had significantly higher QHEI scores than agricultural streams (median = 62 and 40.4, respectively). No other relationships were statistically different, including IBI and land cover category, which may have been due to the small sample size (n = 20). I concluded that future studies may build on these findings by controlling for agricultural drainage types or using precise measures of forested land cover.
Dependence of Inflationary Reconstruction upon Cosmological Parameters

description: The inflationary potential and its derivatives determine the spectrum of scalar and tensor metric perturbations that arise from quantum fluctuations during inflation. The CBR anisotropy offers a promising means of determining the spectra of metric perturbations and thereby a means of constraining the inflationary potential. The relation between the metric perturbations and CBR anisotropy depends upon cosmological parameters -- most notably the possibility of a cosmological constant. Motivated by some observational evidence for a cosmological constant (large-scale structure, cluster-baryon fraction, measurements of the Hubble constant and age of the Universe) we derive the reconstruction equations and consistency relation to second order in the presence of a cosmological constant. We also clarify previous notation and discuss alternative schemes for reconstruction.

Geological characterization of sand-prone subaqueous delta systems: a case study of the Upper Jurassic Sognefjord Formation (Troll Field, Northern North Sea, offshore Norway) and global examples
Creators: name: Patruno, Stefano
Publisher: name: Imperial College London
Year: 2013

description: Core sedimentology, stratigraphic architecture and 3D seismic geomorphology are integrated in order to: (a) demonstrate the criteria for recognition of coarse-grained subaqueous deltas in the stratigraphic record; (b) compare them with modern examples; (c) develop a new method to extract progradation rates from ancient shallow-marine clinoforms; and (d) refine the depositional model of the Upper Jurassic Sognefjord Formation, which forms the main reservoir in the super-giant Troll Field (Norwegian North Sea). The Sognefjord Formation is a 10-200 m thick clastic wedge, deposited in ca. 6 Myr, by a fully marine deltaic system that was sourced from the Norwegian mainland. A series of 10-60 m thick, westerly-dipping subaqueous clinoform sets are developed within this unit and can be mapped for several tens of kilometres along strike. Within each clinoform set, clinothems are formed by regressively stacked sandstone-rich bedsets, devoid of subaerial facies and separated by thin mudstone intervals. Near-horizontal trajectories are observed in each clinoform set, and the sets are stacked vertically. In the eastern half of the field, individual clinoforms are relatively gently dipping (1-6°) and bound thin (10-30 m) clinothems dominated by fine-grained, hummocky cross-stratified sandstones. Towards the west, clinoforms gradually become steeper (5-14°) and bound thicker (15-60 m) clinothems that comprise medium-grained sandstones in their upper parts. Topsets are usually well developed. Quantification of clinoform age and progradation rates is constrained by regionally correlatable bioevents, and relies on exponential age-depth interpolations. The facies break that mirrors the foreset-to-bottomset transition, which represents storm wave base, is subsequently dated, and progradation rates are measured along transects tied to well correlations and seismic interpretations. The results indicate falls in progradation rate (from 500 to 30 km/Myr) and net sediment flux (from 90 to 10 km2/Myr), and a simultaneous rise in vertical sedimentation rate (from 15 to 70 m/Myr) towards the basin; these variations are attributed to the progradation of the subaqueous delta into progressively deeper waters associated with along-shore currents that provide net sediment transport out of the study area, as well as sculpting the linear, elongated clinoforms. Coarse-grained subaqueous deltas provide a new interpretative template that may be applicable to other ancient clinoform-bearing shallow-marine sandstones with reservoir potential, whilst calculation of progradation rates provides a tool to improve reservoir characterisation and near-field exploration by enhancing prediction of reservoir distribution and character.
A New Model of the Gravitational Lens 0957+561 and a Limit on the Hubble Constant

Year: 1995

description: We present a simple mass model for the lensing galaxy in the gravitationally lensed quasar 0957+561. The model is a generalization of the singular isothermal sphere and includes a core radius, $r_c$, and a power-law index, $η$, defined such that mass increases as $r^η$ at large radius. We approximate the galaxy cluster surrounding the lensing galaxy with a quadratic potential described by its convergence $κ$ and shear $γ$. We fit the model to a recent high resolution VLBI map of the two images of 0957+561. We obtain a tight constraint on the radial index, $1.07 < η<1.18$, which means that the lens galaxy is nearly isothermal with increasing mass-to-light ratio out to $15 h^{-1}$ kpc. We also obtain an upper limit on the core radius, $r_c < 330 h^{-1}$ pc. We use the model to calculate the Hubble constant $H_0$ as a function of the time delay $Δτ_{BA}$ between the two images: $H_0 = \left({ 82.5^{+5.9} _{-3.0} }\right) (1 - κ) \left({ Δτ_{BA}/1.1 \,{\rm yr} }\right)^{-1}$ km/s/Mpc. Once $Δτ_{BA}$ is measured, this will provide an upper bound on $H_0$ since $κ$ cannot be negative. In addition, the model degeneracy due to $κ$ can be eliminated if the one-dimensional velocity dispersion $σ$ of the lensing galaxy is measured. We then have $H_0 = \left({ 82.5^{+8.7} _{-5.6} }\right) (σ/ 322\,{\rm km/s})^2 \left({ Δτ_{BA} /1.1 \,{\rm yr} }\right)^{-1}$ km/s/Mpc. We investigate the effects of ellipticity in the lensing galaxy and clumpiness in the lensing cluster and find that these cause little change in our results.

Although conclusions regarding model viability must remain tentative until systematic effects are better understood, there are mild indications that these models have more intermediate scale power than is indicated by presently available CMB anisotropy observational data, with old ($t_0 \geq 15-16$Gyr), high baryon density ($Ω_B \geq 0.0175 h^{-2}$), low density ($Ω_0 \sim 0.2-0.4$) models doing the worst.

description: An exact cosmological solution of Einstein field equations (EFEs) is derived for a dynamical vacuum energy in $f(R,T)$ gravity for Friedmann-Lemaitre-Robertson-Walker (FLRW) space-time. A parametrization of the Hubble parameter is used to find a deterministic solution of EFE. The cosmological dynamics of our model is discussed in detail. We have analyzed the time evolution of physical parameters and obtained their bounds analytically. Moreover, the behavior of these parameters are shown graphically in terms of redshift $`z'$. Our model is consistent with the formation of structure in the Universe. The role of the $f(R,T)$ coupling constant $λ$ is discussed in the evolution of the equation of state parameter. The statefinder and Om diagnostic analysis is used to distinguish our model with other dark energy models. The maximum likelihood analysis has been reviewed to obtain the constraints on the Hubble parameter $H_0$ and the model parameter $n$ by taking into account the observational Hubble data set $H(z)$, the Union 2.1 compilation data set $SNeIa$, the Baryon Acoustic Oscillation data $BAO$, and the joint data set $H(z)$ + $ SNeIa$ and $H(z)$ + $SNeIa$ + $BAO $. It is demonstrated that the model is in good agreement with various observations.

description: We investigate the contribution made by small loops from a cosmic string network as seeds for large-scale structure formation. We show that cosmic string loops are highly correlated with the long-string network on large scales and therefore contribute significantly to the power spectrum of density perturbations if the average loop lifetime is comparable to or above one Hubble time. This effect further improves the large-scale bias problem previously identified in earlier studies of cosmic string models.

Three-dimensional discontinuous spectral/hp element methods for compressible flows
Creators: name: De Grazia, Daniele
Publisher: name: Imperial College London
Year: 2016

description: In this thesis we analyse and develop two high-order schemes which belong to the class of discontinuous spectral/hp element methods focusing on compressible aerodynamic studies and, more specifically, on boundary-layer flows. We investigate the discontinuous Galerkin method and the flux reconstruction approach providing a detailed analysis of the connections between these methods. The connections found enable a better understanding of the broader class of discontinuous spectral/hp element methods. From this perspective it was evident that some of the issues of the discontinuous Galerkin method are also encountered in the flux reconstruction approach, and in particular, the aliasing errors of the two schemes are identical. The techniques applied in the more famous discontinuous Galerkin method for tackling these errors can be also extended to the flux reconstruction approach. We present two dealiasing strategies based on the concept of consistent integration of the nonlinear terms. The first is a localised approach which targets in each element the nonlinearities arising in the problem, while the second is a more global approach which involves a higher quadrature of the overall right-hand side of the discretised equation(s). Both the strategies have been observed to be effective in enhancing the robustness of the schemes considered. We finally present the direct numerical simulation of a high-speed subsonic boundary-layer flow past a three-dimensional roughness element, achieved by means of the compressible aerodynamic solver developed. This type of analyses have been widely performed in the past with approximated theories. Only recently, has DNS been used due to the improvement of numerical techniques and an increase in computational resources for similar studies in low-speed subsonic, supersonic and hypersonic regimes. This thesis takes a first step to close the gap between the results for a high-speed subsonic regime and the results in supersonic and hypersonic regimes.
Numerical modelling of a single symmetric salt finger

description: Described in 1956 as an oceanographic curiosity, salt fingers are now recognized as an important mechanism for vertical transport in fluids that may play a key role in areas so diverse as stellar formation, oceanography and material science and engineering. Complete life cycles of salt fingers will be modeled and analyzed using a combination of finite difference and analytical methods. Some commonly held assumptions about fingering phenomena will be challenged, and some conclusions regarding the origin and maintenance of the finger structure, as well as the dependence of the fingering process on several defining parameters, will also be drawn and discussed.
Torsors of Isotropic Reductive Groups over Laurent Polynomials

Publisher: name: Deutsche Mathematiker-Vereinigung
Year: 2021

description: Let $k$ be a field of characteristic 0. Let $G$ be a reductive group over the ring of Laurent polynomials $R=k[x_1^{\pm 1},...,x_n^{\pm 1}]$. We prove that $G$ is isotropic over $R$ if and only if it is isotropic over the field of fractions $k(x_1,\ldots,x_n)$ of $R$, and if this is the case, then the natural map $H^1_{\it \'et}(R,G)\to H^1_{\it \'et}(k(x_1,\ldots,x_n),G)$ has trivial kernel and $G$ is loop reductive. In particular, we settle in positive the conjecture of V. Chernousov, P. Gille, and A. Pianzola that $H^1_{Zar}(R,G)=*$ for such groups $G$. We also deduce that if $G$ is a reductive group over $R$ of isotropic rank $\ge 2$, then the natural map of non-stable $K_1$-functors $K_1^G(R)\to K_1^G\bigl( k((x_1))...((x_n)) \bigr)$ is injective, and an isomorphism if $G$ is moreover semisimple.

description: The complexes between 14 different Be-salts of oxyacids from groups 13 to 16 with one and two molecules of H2 have been investigated by means of the MP2/aug-cc-pVTZ ab initio molecular orbital theory method, which was found to be reliable for the treatment of these weakly bound species. The main conclusion is that these Be-salts yield rather stable complexes with dihydrogen, with binding energies one order of magnitude larger than other typical H2 complexes reported in the literature. This strong binding is shown to be due to an enhancement of the electron-deficient nature of Be when attached to an oxyacid moiety, which depends more on the type of coordination of the central atom of the oxyacid moiety. The formation of these complexes is followed by a significant lengthening of the H2 internuclear distance and a concomitant red-shift of the H–H stretching frequency, which becomes a good indicator of the strength of the interaction. The charge shifting from the bonding region of the H2 molecule to the interboundary Be···H2 region is the physical phenomenon behind the stability of these complexes. Accordingly, the most important contributor to this stability is the inductive term, followed by the electrostatic interactions. The ability of Be to bind H2 is enhanced by the angular arrangement of the O–Be–O electron-acceptor group.

Developing and evaluating expertise in colonoscopy
Creators: name: Patel, Kinesh Pradip
Publisher: name: Imperial College London
Year: 2015

description: The quality and safety of colonoscopy have become of paramount importance with the worldwide expansion in the utilisation of this procedure, especially with the introduction of colorectal cancer screening in many countries. It is well known that colonoscopic performance varies significantly between practitioners. This thesis explores the effects of assessment in colonoscopy and polypectomy on performance and practice as well as trying to define the factors which differentiate the very best practitioners from the clinically competent. Until 2011, there was no formalised way of certifying polypectomy competence. We looked at the effects of the introduction of mandatory polypectomy assessment on trainee endoscopists applying for certification of competency in the United Kingdom. This work showed that documentation of polypectomy competence significantly improved after these changes were introduced. A global survey of polypectomy practice was undertaken to evaluate international guidance on polypectomy skills training and how trainers deliver teaching on polypectomy around the world, as well as trainees’ experience of gaining polypectomy skills. Significant variability in endoscopists’ experience of polypectomy training was found with few formal national guidelines published. This led to an evaluation of expert endoscopists who underwent an accreditation process with some similarities before commencing Bowel Cancer Screening (BCS). We examined whether it was possible to predict future performance from a single assessment and found that criteria used to assess whether candidates were competent could not predict the best performers from those who passed. Several hundred expert BCS colonoscopists were then monitored over a three year period to determine changes in performance over time and whether long-term performance could be predicted. The best predictors of performance over time for all metrics were initial performance. In order to identify key features of expertise in endoscopy, experienced colonoscopists were interviewed to distinguish characteristics of true endoscopic experts. These interviews revealed the importance of both technical and non-technical skills in defining expertise.

description: The variability of 30 PG quasars has been observed in the red band during three years. A rest-frame structure function analysis shows an increase of variability with the time interval up to 0.2 mag r.m.s. after two years. A comparison with the IUE data available for PG quasars shows that the variability increases with the rest-frame frequency at each time interval. Evidence for this effect is supported by the analysis of the average variability of other published quasar samples. The effect can completely account for the increase of variability with redshift found in other studies.

description: The tensor-vector contraction (TVC) is the most memory-bound operation of its class and a core component of the higher-order power method (HOPM). This paper brings distributed-memory parallelization to a native TVC algorithm for dense tensors that overall remains oblivious to contraction mode, tensor splitting and tensor order. Similarly, we propose a novel distributed HOPM, namely dHOPM3, that can save up to one order of magnitude of streamed memory and is about twice as costly in terms of data movement as a distributed TVC operation (dTVC) when using task-based parallelization. The numerical experiments carried out in this work on three different architectures featuring multi-core and accelerators confirm that the performances of dTVC and dHOPM3 remain relatively close to the peak system memory bandwidth (50%-80%, depending on the architecture) and on par with STREAM benchmark figures. On strong scalability scenarios, our native multi-core implementations of these two algorithms can achieve similar and sometimes even greater performance figures than those based upon state-of-the-art CUDA batched kernels. Finally, we demonstrate that both computation and communication can benefit from mixed precision arithmetic also in cases where the hardware does not support low precision data types natively.

A Pairing on the Cuspidal Eigenvariety for $\mathrm{GSp}_{2g}$ and the Ramification Locus
Creators: name: Wu, Ju-Feng
Publisher: name: Deutsche Mathematiker-Vereinigung

description: In the present paper, we first construct a pairing on the space of analytic distributions associated with $\mathrm{GSp}_{2g}$. By considering the overconvergent parabolic cohomology groups and following the work of Johansson-Newton, we construct the cuspidal eigenvariety for $\mathrm{GSp}_{2g}$. The pairing on the analytic distributions then induces a pairing on some coherent sheaves of the cuspidal eigenvariety. As an application, we follow the strategy of Bella\"{i}che to study the ramification locus of the cuspidal eigenvariety over the corresponding weight space.

Improved shot noise limit of the YbF EDM experiment
Creators: name: Rabey, Isabel
Publisher: name: Imperial College London
Year: 2016

description: The electron is predicted to have a small electric dipole moment (EDM). This fundamental property characterises the distortion of the electron's almost perfectly spherical charge distribution. The size of this distortion (de) is intimately connected to the breaking of time reversal symmetry (T) in nature. The Standard Model of particle physics, which contains a small amount of T-asymmetry, predicts a tiny, non-zero value of the electron EDM, |de| ≃ 10^-38 e.cm. However, many extensions to the Standard Model, which naturally include additional T-violating effects, also predict much larger values of de that should be detectable using current experimental techniques. Measurements of the electron's EDM constrains these theories, making these experiments a powerful tool in the search for physics beyond the Standard Model. The most precise measurements of the electron EDM have been made using paramagnetic atoms and moleules. This thesis describes the progress made towards a new measurement of the electron EDM using the polar, paramagnetic molecule, YbF. A new state preparation technique is described that optically pumps most of the population from the first and second rotationally excited states into a single hyper fine component of the ground state. This increases the number of molecules entering the experiment by a factor of 6. A new state-selective detection scheme is also described, where multiple laser frequencies are used so that each molecule scatters many photons. This has increased detection efficiency by a factor of 20. In order to reduce magnetic noise in the experiment, new electric field plates have been introduced into the interaction region which have reduced the magnetic Johnson noise by a factor of 100. Together, these improvements increase statistical sensitivity by a factor of 11.4 over the last EDM measurement made using YbF. With an enhanced sensitivity of (5x10^-27/sqrt(Nb)) e.cm, we can expect to measure the electron's EDM more precisely than ever before, constraining T-violating physics at a higher energy scale.

description: In this study, a carbon paste electrode modified with a novel 1-(3-aminopropyl) imidazole functionalised crosslinked chlorosulfonated poly(styrene)-divinyl benzene polymer was used for selective and sensitive determination of the trace amounts of Pb2+, Cu2+ and Hg2+ ions by square wave anodic stripping voltammetry. The effect of some parameters such as paste composition, pH, preconcentration time, reduction potential and time, type of supporting electrolyte and potential scan rate on the determination of metal ions were investigated to find the optimal conditions. The effective open-circuit accumulation of the studied metal ions was succeeded only by the modification of the carbon paste electrode with functional polymer. For 6 min open-circuit preconcentration, the detection limit of Pb2+, Cu2+ and Hg2+ was found to be 5, 9 and 14 µgL−1, respectively at 100 mVs−1. The results confirmed that the lower concentration levels of these trace metal ions can be determined with the increase of preconcentration time and/or potential scan rate. Good detection limits and large dynamic concentration ranges were also obtained for their binary and ternary mixtures. The optimised method was successively applied to determine the concentration of Pb2+, Cu2+ ions in the tap water sample and Cu2+ ion in the waste water sample in the presence of possible interfering species (RSD<1%, recoveries 96–110% for 4 min preconcentration).

description: We report evidence from the 3B Catalogue that long ($T_{90} > 10$ s) and short ($T_{90} < 10$ s) gamma-ray bursts represent distinct source populations. Their spatial distributions are significantly different, with long bursts having $\langle V/V_{max} \rangle = 0.282 \pm 0.014$ but short bursts having $\langle V/V_{max} \rangle = 0.385 \pm 0.019$, differing by $0.103 \pm 0.024$, significant at the $4.3 σ$ level. Long and short bursts also differ qualitatively in their spectral behavior, with short bursts harder in the BATSE (50--300 KeV) band, but long bursts more likely to be detected at photon energies > 1 MeV. This implies different spatial origin and physical processes for long and short bursts. Long bursts may be explained by accretion-induced collapse. Short bursts require another mechanism, for which we suggest neutron star collisions. These are capable of producing neutrino bursts as short as a few ms, consistent with the shortest observed time scales in GRB. We briefly investigate the parameters of clusters in which neutron star collisons may occur, and discuss the nuclear evolution of expelled and accelerated matter.
