description: It has long been argued that the radial distribution of globular clusters (GCs) in the Fornax dwarf galaxy requires its dark matter halo to have a core of size $\sim 1$ kpc. We revisit this argument by investigating analogues of Fornax formed in E-MOSAICS, a cosmological hydrodynamical simulation that self-consistently follows the formation and evolution of GCs in the EAGLE galaxy formation model. In EAGLE, Fornax-mass haloes are cuspy and well described by the Navarro-Frenk-White profile. We post-process the E-MOSAICS to account for GC orbital decay by dynamical friction, which is not included in the original model. Dynamical friction causes 33 per cent of GCs with masses $M_{\rm GC}\geq4\times10^4 {~\rm M_\odot}$ to sink to the centre of their host where they are tidally disrupted. Fornax has a total of five GCs, an exceptionally large number compared to other galaxies of similar stellar mass. In the simulations, we find that only 3 per cent of the Fornax analogues have five or more GCs, while 30 per cent have only one and 35 per cent have none. We find that GC systems in satellites are more centrally concentrated than in field dwarfs, and that those formed in situ (45 per cent) are more concentrated than those that were accreted. The survival probability of a GC increases rapidly with the radial distance at which it formed ($r_{\rm init}$): it is 37 per cent for GCs with $r_{\rm init} \leq 1$ kpc and 92 per cent for GCs with $r_{\rm init} \geq 1$ kpc. The present-day radial distribution of GCs in E-MOSAICS turns out to be indistinguishable from that in Fornax, demonstrating that, contrary to claims in the literature, the presence of five GCs in the central kiloparsec of Fornax does not exclude a cuspy DM halo.

description: Surface curvature is used in a number of areas in computer graphics including mesh simplification, surface modeling and denoising, feature detection, and non-photorealistic line drawing techniques. Most applications must estimate surface curvature, due to the use of discrete models such as triangular meshes. Until recently, curvature estimation has been limited to CPU algorithms, forcing object geometry to reside in main memory. More computational work is being done directly on the GPU, and it is increasingly common for object geometry to only exist in GPU memory. Examples include vertex skinned animations, isosurfaces from GPU-based surface reconstruction algorithms, or triangular meshes generated by hardware tessellation units. All of these types of geometry can be large in size and transferring the data to the CPU is cost prohibitive in interactive applications, especially if the mesh changes every frame. Thus, for static models, CPU algorithms for curvature estimation are a reasonable choice, but for models where the object geometry only resides on the GPU, CPU algorithms limit performance. I introduce a GPU algorithm for estimating curvature in real-time on arbitrary triangular meshes residing in GPU memory. I test my algorithm in a line drawing system with a vertex-skinned animation system and a GPU-based isosurface extraction system.

description: After a brief review of the BFKL approach to Regge processes in QCD and in supersymmetric (SUSY) gauge theories we propose a strategy for calculating the next-to-next-to-leading order corrections to the BFKL kernel. They can be obtained in terms of various cross-sections for Reggeized gluon interactions. The corresponding amplitudes can be calculated in the framework of the effective action for high energy scattering. In the case of N=4 SUSY it is also possible to use the Bern-Dixon-Smirnov (BDS) ansatz. For this purpose the analytic properties of the BDS amplitudes at high energies are investigated, in order to verify their self-consistency. It is found that, for the number of external particles being larger than five, these amplitudes, beyond one loop, are not in agreement with the BFKL approach which predicts the existence of Regge cuts in some physical channels.

description: We derive hydrodynamic-like equations that are applicable to short-time scale color phenomena in the quark-gluon plasma. The equations are solved in the linear response approximation, and the gluon polarization tensor is derived. As an application, we study the collective modes in a two-stream system and find plasma instabilities when the fluid velocity is larger than the speed of sound in the plasma. The chromo-hydrodynamic approach, discussed here in detail, should be considered as simpler over other approaches and well-designed for numerical studies of the dynamics of an unstable quark-gluon plasma.

Retroflex phones are especially targeted, and Noble asks for Joseph's judgments as to the similarity between phones in different lexical items. They later transition into basic sentence elicitation. Possible correspondence with unknown recordings are summarized as "28/6-1 > 28/6-2." File 2018-03.003_B begins with the same configuration as the beginning of 2018-03.003_B. At 5'35" Noble inquires about terms for constellations. At 7'15" Joseph gives procedural text in Wapishana describing "Wapishana working together" (per metadata written on the reel box), with possible correspondence to unknown notes summarized as "29/0-1 > 30/6-2." At 10'15" Noble records "school girls" (see above) asking them for translations of basic phrases; one of them is Lawrence Joseph's cousin, name heard as Alem (possible notebook correspondences being "30/6-2>3"). At 14'58" Joseph speaks with a girl ("30/6-6"). In what follows, there are three breaks in the recording at 17'05", 18'33", and 19'51". According to metadata written on the reel box, this should correspond to four staged texts, "as in a store," "on hunting," "on Doris et al.," "on going to his field." (The possible notebook correspondences to these four segments are, respectively, "30/6-8," "2/7:2-4," "2/7-5," "3/7:1-4.") At 21'29" the date of recording is indicated as "Saturday afternoon, July 3rd," and sentence elicitation follows ("3/7-5").

description: Fragment energy spectra of neutron deficient isotopes are significantly more energetic than those of neutron rich isotopes of the same element. This trend is well beyond what can be expected for the bulk multi-fragmentation of an equilibrated system. It can be explained, however, if some of these fragments are emitted earlier through the surface of the system while it is expanding and cooling.

Redundant Formats for Faster Floating-Point Addition

Publisher: name: Maryland Shared Open Access Repository
Year: 2007
Subjects: Engineering, Electronics and Electrical (0544)

description: The current standard two-path floating-point arithmetic algorithm's latency is on the order of 2 lg n. The normalization required by the standard two-path algorithm leaves outputs in a normalized non-redundant form, which constrains any new approaches that try to improve upon the floating-point adder architecture. Reducing the latency of floating-point addition would help in all floating-point operations, especially in conditional branches that are present in iterative methods. In this work, we propose two similar approaches that reduce the latency, increase the throughput, and minimize the critical path of the floating-point adder architecture by pipelining the two log2 n operations of addition and a variable shift that inherently exist within both the far and near paths of the standard two-path algorithm. We leave the intermediate results in a redundant format in case they are needed by the immediate successor instruction. Whether or not the result is needed by the next instruction the intermediate redundant result has time to be converted to a normalized non-redundant form while the next addition occurs. We accomplish these goals while adhering to the input and output constraints of the IEEE standard for binary floating-point arithmetic.

description: In the past few years, wireless sensor networks (WSNs) have become important in different applications because of their robustness in hostile environments. WSNs need to perform in a timely manner in the face of interference, attacks, accidents, and failures. Being a battery operated system, there is a trade-off between performance and energy utilization. In this thesis we focus WSNs on efficiency and consider ways to improve the performance of WSNs when sensors become damaged, resulting in poor input signal quality. When all other components of the sensor like the processor, memory, and battery working fine, our proposed solution is to learn to undo the damage in software by training on neighbors sensor values.

description: This dissertation investigates the applications of hyperspectral image processing algorithms in recently reconfigurable DSP systems. To date, engineers have been using the Field Programmable Gate Array (FPGA) as the core processing element of most reconfigurable computers. These FPGA-built processing elements completely avoid the instruction-fetch, load/store bottlenecks of the conventional von Neumann architectures in most general purpose processors and DSP processors. FPGA-based systems truly achieve parallel processing, executing algorithms based on the inherent parallelism of the hardware. In addition, FPGAs are far more scalable into the higher throughput realms because of their dedicated logic for I/O functions which is of particular importance when dealing with data from sensor imaging systems. In this dissertation, two hyperspectral image processing algorithms, Adaptive Causal Anomaly Detection (ACAD) used for anomaly detection and Block-of-Skewer based Pixel Purity Index (BOS-PPI) for endmember extraction will be investigated. Each of them demonstrates different level of challenging tasks to be resolved in the reconfigurable computing environment. For the ACAD algorithm the major challenge of its FPGA implementation is the calculation of the inverse of correlation matrix in near real-time. Since Hyperspectral image data are collected by hundreds or thousands of spectral bands, their large scale sample correlation matrices require a vast amount of time to calculate its inversion. In order to cope with this problem, the QR-Decomposition based matrix inversion is implemented via the COordinate Rotation DIgital Computer (CORDIC). In addition, the Matrix Inversion Lemma (MIL) is also used to reduce the computational complexity induced by the near real-time matrix inversion computation. As for the Block-of-Skewers based PPI, its FPGA implementation is focused on systolic array design due to its inherent parallelism. Several different block designs will be implemented and compared in this dissertation. The FPGA design in this research work sets a stage towards future development of new reconfigurable systems for on-board and real-time processing of many hyperspectral image processing algorithms.

description: A method of chaos reduction for Hamiltonian systems is applied to control chaotic advection.

description: Several authors have employed Finite Element Analysis (FEA) for stress and strain analysis in orthopaedic biomechanics. Unfortunately, the use of three-dimensional models is time consuming and consequently the number of analysis to be performed is limited. The authors have investigated a new method allowing automatically 3D mesh generation for structures as complex as bone for example. This method called Mesh-Matching (M-M) algorithm generated automatically customized 3D meshes of bones from an already existing model. The M-M algorithm has been used to generate FE models of ten proximal human femora from an initial one which had been experimentally validated. The new meshes seemed to demonstrate satisfying results.
Tom Burrow’s "Sculpture of Concrete, Sculpture of Dreams" or, looking for the utopian in the everyday
Creators: name: Anderson, Andrea Karin
Publisher: name: University of British Columbia

description: The plethora of Utopian ideas that circulated in North America and Europe in the 1960's and 1970's emerged in the work of Vancouver artist Tom Burrows. Utopianisms formed objectives for much of the social and political activism throughout the period, compelling Burrows to incorporate them into his artistic practice. Chapter One, The Utopian Moment, describes the most powerful Utopian ideas circulating in Vancouver at the time, their uneasy alignments and overt contradictions. Although contradictory, they were still instructive; and many artists responded with socially and politically charged art. In Chapter Two, The Utopian in Art, I contextualize Burrows' work with that of other artists whose ambitions were similar. Chapters Three and Four demonstrate Burrows' conflicted position by presenting two views of his work on the Maplewood Mudflats. In Chapter Three, The Mudflats as Utopian Ladscape, characterize this work as "useless" and romantic, as part of the 'aesthetic dimension' defined by Frankfurt School critical theory. Chapter Four, The Most Beautiful Sculpture, foregrounds the activist aspect of Burrows' work on the flats. This dialectic of beauty and utility informs Burrows' work throughout the period, from the participatory Sand Pile installation to the aestheticism of the sculpture comprising the Temptations of Mao Tse-Tung exhibition and the anti-aestheticism of the Squat Doc[ument]. The Squat Doc was a Utopian view of squatted and self-help housing at several sites in Europe, Africa and Asia. It is the subject of Chapter Five, The Everyday Utopia of Squatting. Burrows' conflicting and shifting positions were not limited to his own practice, but representative of artistic practices at the time. I want to demonstrate that Burrows' was among the most committed to fundamental change in art and society in this period.

description: Recently, laser-assisted chemical vapor deposition was used to synthesize a free-standing, continuous, and stable monolayer amorphous carbon (MAC). MAC is a pure carbon structure composed of randomly distributed five, six, seven, and eight atom rings, which differs from disordered graphene. More recently, amorphous MAC-based nanotubes (a-CNT) and nanoscrolls (A-CNS) were proposed. In this work, we have investigated (through fully atomistic reactive molecular dynamics simulations) the mechanical properties and melting points of pristine and a-CNT and a-CNS. Results showed that a-CNT and a-CNS have distinct elastic properties and fracture patterns concerning their pristine analogs. Both a-CNT and a-CNS presented a non-elastic regime before their total rupture, whereas the CNT and CNS undergo a direct conversion to fractured forms after a critical strain threshold. The critical strain for the fracture of the a-CNT and a-CNS are about 30% and 25%, respectively, and they are lower than the corresponding CNT and CNS cases. Although less resilient to tension, the amorphous tubular structures have similar thermal stability in relation to the pristine cases with melting points of 5500K, 6300K, 5100K, and 5900K for a-CNT, CNT, a-CNS, and CNS, respectively. An interesting result is whereas the behavior of the pristine systems is substantially different depending on the system being a nanotube or a nanoscroll, thus indicating that the topology plays an important role, the same is not true for the amorphous version of the nanostructures, thus indicating that the structural disorder overcomes the topological features.

We give a parameterization of formal deformations in terms of two-forms obeying a cubic equation. The notion of equivalence is discussed in detail. We show that the obstruction for the construction of deformations order by order lies in the third Lie algebroid cohomology of the Dirac structure. However, the classification of inequivalent first order deformations is not given by the second Lie algebroid cohomology but turns out to be more complicated.

description: Refraction of light is one of the important phenomena that contribute to the perception of realism and is responsible for widely observed effects such as caustics. We describe an image-space algorithm to simulate refraction of light through a dynamic object. Unlike previous approaches, our technique achieves refraction through multiple interfaces at interactive frame-rates and does not require any pre-processing. Each stage of our algorithm runs entirely on the GPU and fits into the existing raster-based pipeline. Multiple refractions are simulated using depth layers obtained from a dynamically voxelized polygonal model and by using an image-space ray tracing technique. We also describe an accurate surface interpolation technique used to obtain surface normals using the depth layers. Our implementation suits the standard rasterization pipeline and achieves visually plausible results at interactive frame rates even for the dynamic scenes involving multiple refractive objects.

description: The dynamics of multiphoton transitions in a two-level spin system excited by transverse microwave and longitudinal RF fields with the frequencies w_{mw} and w_{rf}, respectively, is analyzed. The effective time-independent Hamiltonian describing the "dressed" spin states of the "spin + bichromatic field" system is obtained by using the Krylov-Bogoliubov-Mitropolsky averaging method. The direct detection of the time behavior of the spin system by the method of nonstationary nutations makes it possible to identify the multiphoton transitions for resonances w_{0} = w_{mw} + rw_{rf} (w_{0} is the central frequency of the EPR line, r = 1, 2), to measure the amplitudes of the effective fields of these transitions, and to determine the features generated by the inhomogeneous broadening of the EPR line. It is shown that the Bloch-Siegert shifts for multiphoton resonances at the inhomogeneous broadening of spectral lines reduce only the nutation amplitude but do not change their frequencies.

description: We present a volume format which is capable of representing complex reconstructions as well as a fast isosurface rendering algorithm. Our volume format consists of a set of densely packing tetrahedral polynomials in Bernstein form, each constrained to provide continuity across face boundaries. We de?ne a speci?c class of tetrahedral partition suitable for our method, along with a least-squares approximation method to generate data in this format as approximations to arbitrary continuous volumes. Our volume format is closed under convolution with scalar volumes, so by representing reconstruction ?lters in our format we can create convolved volumes easily. We also present a fast rendering algorithm which maintains interactive rates for most volumes up to 128x128x128 resolution. Our results include analytic and observational error for how our format approximate several common volume reconstructions, as well as space requirements and rendering speed.

description: Controversies over the validity, scientific status and cultural significance of psychoanalysis have continued unabated since its foundation at the beginning of the twentieth century. This paper will focus on one debate, which took place in England in the mid 1920s, so as to give historical specificity to a striking example of a seemingly perennial conflict. Amongst the protagonists were John Maynard Keynes, economist and world banker, and Arthur Tansley, founder of British ecology. Through examining the controversy, the manner in which psychoanalysis was articulated with other fields for these thinkers will be explored, including the psychological foundations for Keynesian economics.

description: Rare-earth monopnictides display rich physical behaviors, featuring most notably spin and orbital orders in their ground state. Here, we grow ErBi single crystal and study its magnetic, thermal and electrical properties. An analysis of the magnetic entropy and magnetization indicates that the weak magnetic anisotropy in ErBi possibly derives from the mixing effect, namely the anisotropic ground state of Er3+ (4f11) mingles with the isotropic excited state through exchange interaction. At low temperature, an extremely large magnetoresistance (~104%) with a parabolic magnetic-field dependence is observed, which can be ascribed to the nearly perfect electron-hole compensation and ultrahigh carrier mobility. When the magnetic field is rotated in the ab (ac) plane and the current flows in the b axis, the angular magnetoresistance in ErBi shows a twofold (fourfold) symmetry. Similar case has been observed in LaBi where the anisotropic Fermi surface dominates the low-temperature transport. Our theoretical calculation suggests that near the Fermi level ErBi shares similarity with LaBi in the electronic band structures. These findings indicate that the angular magnetoresistance of ErBi could be mainly determined by its anisotropic Fermi surface topology. Besides, contributions from several other possibilities, including the spin-dependent scattering, spin-orbit scattering, and demagnetization correlation to the angular magnetoresistance of ErBi are also discussed.

description: Definitive embeddings remain a fundamental challenge of computational musicology for symbolic music in deep learning today. Analogous to natural language, music can be modeled as a sequence of tokens. This motivates the majority of existing solutions to explore the utilization of word embedding models to build music embeddings. However, music differs from natural languages in two key aspects: (1) musical token is multi-faceted -- it comprises of pitch, rhythm and dynamics information; and (2) musical context is two-dimensional -- each musical token is dependent on both melodic and harmonic contexts. In this work, we provide a comprehensive solution by proposing a novel framework named PiRhDy that integrates pitch, rhythm, and dynamics information seamlessly. PiRhDy adopts a hierarchical strategy which can be decomposed into two steps: (1) token (i.e., note event) modeling, which separately represents pitch, rhythm, and dynamics and integrates them into a single token embedding; and (2) context modeling, which utilizes melodic and harmonic knowledge to train the token embedding. A thorough study was made on each component and sub-strategy of PiRhDy. We further validate our embeddings in three downstream tasks -- melody completion, accompaniment suggestion, and genre classification. Results indicate a significant advancement of the neural approach towards symbolic music as well as PiRhDy's potential as a pretrained tool for a broad range of symbolic music applications.

There are explanations of variation, that Farabee was at times incorrect, etc. File 2018-03.002_B continues with Noble's checking of Farabee's data, as recorded on July 24, 1965, beginning with "bruise." At 5'16" Noble carries out elicitation on "Wapishana nouns which change in the possessed form from that in the unpossessed form." He indicates that "words come largely from the notes taken on the 23rd of July." The latter includes possessive forms like "owner of [X]." Possible correspondences to notebooks are summarized as "continues to call on 24/7; possessive forms 23/7 to 25/7; notes of 17/8."

description: In this paper we obtain several tight bounds on different types of alliance numbers of a graph: (global) defensive alliance number, global offensive alliance number and global dual alliance number. In particular, we investigate the relationship between the alliance numbers of a graph and its algebraic connectivity, its spectral radius, and its Laplacian spectral radius.

description: File 2018-03.001_A begins with Veronica Johnson telling a story in Wapishana about how she heard of a murder; at 3'12" it continues with Christine George providing Atorai vocabulary with the assistance of Wapishana-speaking translator Lawrence Joseph. The vocabulary was "first given" on August 4, 1965, and appears to correspond to unknown notebook pages abbreviated "4/8-1-14." File 2018-03.001_B begins with Christine George providing Atorai vocabulary in the same format, here the date of recording indicated as August 12, 1965. At 26'30" G.K. Noble begins checking Wapishana vocabulary with Lawrence Joseph; Noble attempts to pronounce several tokens himself and Joseph provides additional explanation for some terms. The first Atorai segment appears to correspond to to unknown notebook pages abbreviated "5/8-14," with the final segment corresponding to "25/6-2&3."
»Verschiedene Schicksale«. Das Frühwerk Jacques Lacans und die Phänomenologie
Creators: name: Schmidgen, Henning
Publisher: name: Österreichische Zeitschrift für Geschichtswissenschaften
Year: 2003

description: Many of the methodological restrictions associated with the traditional history of ideas can be overcome by focusing more closely on the history of the material substrata which served to transmit knowledge. This argument is substantiated here with respect to the relationship between the early work of Jacques Lacan (1901-1981) and the disciplines of phenomenology (E. Husserl, M. Seheier), phenomenological psychopathology, and dynamic psychiatry (K. Jaspers, E. Minkowski, E. Kretschmer). By examining in detail the genesis of Lacan's 1932 doctoral thesis on paranoia and related texts, one realizes that it was not so much Husserl, but rather Scheler's book on the nature and forms of sympathy (1913/1923) which contributed most to the elaboration of Lacan's later theory of the imaginary. lt also becomes evident that Lacan's incorporation of certain German philosophical terms (Ausschaltung, Aufhebung) into his French writings was not devoid of productive misreadings (»Aufhaltung phenomenologique«, »Aufhebung husserlienne«). Hence, it can be suggested that both Lacan's psychoanalytic work and also his early texts are rooted in a space >in-between languages< (French and German).

description: We investigate the motion of a massive particle constrained to move along a path consisting of two line segments on a vertical plane under an arbitrary conservative force. By fixing the starting and end points of the track and varying the vertex horizontally, we find the least-time path. We define the angles of incidence and refraction similar to the refraction of a light ray. It is remarkable that the ratio of the sines of these angles is identical to the ratio of the average speeds on the two partial paths as long as the horizontal component of the conservative force vanishes.

The need for equitable representation on and increase in the membership of the United Nations Security Council
Creators: name: Adeleke, Adewale Wale
Publisher: name: University of British Columbia

description: The United Nations is composed of six principal organs. These are the General Assembly, the Security Council, the Economic and Social Council, the International Court of Justice, the Secretariat, and the Trusteeship Council. But, as the organ conferred with the primary responsibility for the maintenance of international peace and security, amongst other vital functions, the Security Council is without doubt the most important organ of the United Nations. At the San Francisco Conference which led to the establishment of the U.N., it was agreed that the Security Council shall consist of 11 members, 5 permanent and 6 non-permanent. In recognition of the fact that peace could not be maintained without the cooperation of the Major Powers (China, U.S.S.R., U.S.A., U.K., and France) the 5 Major Powers became Permanent Members of the Security Council. Additionally, decisions of the Council on substantive matters was subject to the concurring votes, so called veto right, of all five Permanent Members. Between 1945 and 1963, membership of the United Nations increased from 51 to 113. Thus, the Security Council was increased from 11 to 15, by the creation of 4 more non-permanent seats. Since 1963, U.N. membership has increased from 113 to 185 with most of the new members coming from Africa and Asia. The present distribution of permanent seats does not reflect the increased representation from Africa, Latin America, and Asia, nor the emergence of economic giants such as Japan and Germany, the second and third largest contributors to the U.N. regular budget. Furthermore, the abuse of the veto has led to a call for an elimination or a limitation of the veto. In addressing these problems, I divided the U.N. into four time periods: the pre-U.N., the San Francisco Conference, Security Council practice from 1945 to 1990, and post cold-war practice, 1991 till present. In examining each period I relied on official documents including the Dumbarton Oaks Proposals, the San Francisco Conference Papers, and Repertory of Security Council Practice. My conclusion is that there should be an increase in the permanent and nonpermanent seats of the Security Council to make it more representative, and that while the veto needs to be preserved, there is a need to limit the scope of the veto.
The role of dust destruction and dust growth in the evolution of the interstellar medium

description: We use Milky Way-like chemodynamical simulations with a new treatment for dust destruction and growth to investigate how these two processes affect the properties of the interstellar medium in galaxies. We focus on the role of two specific parameters: f_des (a new parameter that determines the fraction of dust destroyed in a single gas particle surrounding supernova) and C_s (the probability that a metal atom or ion sticks to the dust grain after colliding, i.e., the sticking coefficient) in regulating the amount and distribution of dust, cold gas and metals in galaxies. We find that simulated galaxies with low f_des and/or high C_s values produce not only more dust, but they also have a shallower correlation between dust surface density and total gas surface density, and a steeper correlation between dust-to-gas ratio and metallicity. Only for values of f_des between 0.01 and 0.02, and of C_s between 0.5 and 1 our simulations produce an average slope of the dust-to-gas ratio versus metallicity relation consistent with observations. f_des values correspond to a range of a total fraction of dust destroyed by a single supernova between 0.42 and 0.44. Lastly, we compare predictions of several simulations (with different star formation recipes, gas fractions, central metallicities, and metallicity gradients) to the spatially resolved M101 galaxy, and conclude that metallicity is the primary driver of the spatial distribution of dust, while dust-to-gas ratio controls the cold gas distribution, as it regulates the atomic-to-molecular hydrogen conversion rate.

description: At this summer school, I have tried to describe a general approach to quantum transport problems based on the Non-equilibrium Green Function (NEGF) method . I will not repeat this treatment here. Instead I will use this article to draw attention to a core issue in quantum transport and how it is modeled within the NEGF method. Specifically, I will discuss what constitutes a dephasing process and how the standard descriptions may need to be extended to include what I will call hot spin effects. These involve a number of subtle issues that tend to get hidden in a purely formal description. So I have chosen instead to illustrate the concepts using a concrete device, which is specially engineered to enhance its sensitivity to spin dephasing and hot spin effects.

description: We study the dynamics of multiple scalar fields and a barotropic fluid in an FLRW-universe. The scalar potential is a sum of exponentials. All critical points are constructed and these include scaling and de Sitter solutions. A stability analysis of the critical points is performed for generalized assisted inflation, which is an extension of assisted inflation where the fields mutually interact. Effects in generalized assisted inflation which differ from assisted inflation are emphasized. One such a difference is that an (inflationary) attractor can exist if some of the exponential terms in the potential are negative.

Shadow of nulllike and timelike naked singularities without photon spheres

description: In this paper, we derive general conditions for a shadow to occur, without a photon sphere in a spacetime, caused by central nulllike or timelike naked singularities. Using these conditions, we propose classes of spacetimes which have nulllike and timelike naked singularities at the center, and that fulfill these `shadow without photon sphere' conditions. Considering additional asymptotically flat conditions, we show that, for a fixed Schwarzschild mass, the timelike naked singularities can cast a shadow of a size that is equal to, greater or smaller, than the size of a black hole shadow. On the other hand, the size of shadow of a nulllike naked singularity is always less than that of a black hole. Such novel features of shadows of nulllike and timelike naked singularities in the absence of photon spheres may help us to distinguish between black holes and naked singularities observationally.

description: We propose a scenario where inflation is driven by non-minimally coupled massive vector fields. In an isotropic homogeneous universe these fields behave in presicely the same way as a massive minimally coupled scalar field. Therefore our model is very similar to the model of chaotic inflation with scalar field. For vector fields the isotropy of expansion is achived either by considering a triplet of orthogonal vector fields or for the expense of $N$ randomly oriented vector fields. In the last case the substantial anisotropy of the expansion of order $1/\sqrt{N}$ survives until the end of inflation. The lightest vector fields might also force the late time acceleration of the Universe.
