Abstract:
A phase separation model for stripes has found good agreement with photoemission experiments and with other studies which suggest a termination of the striped phase in the slightly overdoped regime. Here the model is extended in a number of respects. In particular, a discussion of the nature of the charged stripes is presented, suggesting how density waves, superconductivity, and strong correlations can compete with the quantum size effects inherent in narrow stripes. The anomalous doping dependence of the chemical potential is explained.

Abstract:
This paper presents a global and local tensor sparse approximation (GLTSA) model for removing the stripes in hyperspectral images (HSIs). HSIs can easily be degraded by unwanted stripes. Two intrinsic characteristics of the stripes are (1) global sparse distribution and (2) local smoothness along the stripe direction. Stripe-free hyperspectral images are smooth in spatial domain, with strong spectral correlation. Existing destriping approaches often do not fully investigate such intrinsic characteristics of the stripes in spatial and spectral domains simultaneously. Those methods may generate new artifacts in extreme areas, causing spectral distortion. The proposed GLTSA model applies two ℓ 0 -norm regularizers to the stripe components and along-stripe gradient to improve the destriping performance. Two ℓ 1 -norm regularizers are applied to the gradients of clean image in spatial and spectral domains. The double non-convex functions in GLTSA are converted to single non-convex function by mathematical program with equilibrium constraints (MPEC). Experiment results demonstrate that GLTSA is effective and outperforms existing competitive matrix-based and tensor-based destriping methods in visual, as well as quantitative, evaluation measures.

Abstract:
The surface morphology of the anodic aluminum oxide (AAO) prepared with different surface coating has been studied by AFM and SEM. Under optimized condition, highly ordered stripe patterns have been obtained. These regular patterns, including random stripes and regular stripes, show strong dependence on the crystal orientation of the aluminum substrate. This method can be developed into a novel nanoscale fabrication technique.

Abstract:
The entire functional even-skipped locus of Drosophila melanogaster is contained within a 16 kilobase region. As a transgene, this region is capable of rescuing even-skipped mutant flies to fertile adulthood. Detailed analysis of the 7.7 kb of regulatory DNA 3′ of the transcription unit revealed ten novel, independently regulated patterns. Most of these patterns are driven by non-overlapping regulatory elements, including ones for syncytial blastoderm stage stripes 1 and 5, while a single element specifies both stripes 4 and 6. Expression analysis in gap gene mutants showed that stripe 5 is restricted anteriorly by Kruppel and posteriorly by giant, the same repressors that regulate stripe 2. Consistent with the coregulation of stripes 4 and 6 by a single cis-element, both the anterior border of stripe 4 and the posterior border of stripe 6 are set by zygotic hunchback, and the region between the two stripes is ‘carved out’ by knirps. Thus the boundaries of stripes 4 and 6 are set through negative regulation by the same gap gene domains that regulate stripes 3 and 7 (Small, S., Blair, A. and Levine, M. (1996) Dev. Biol. 175, 314–24), but at different concentrations. The 3′ region also contains a single element for neurogenic expression in ganglion mother cells 4–2a and 1–1a, and neurons derived from them (RP2, a/pCC), suggesting common regulators in these lineages. In contrast, separable elements were found for expression in EL neurons, U/CQ neurons and the mesoderm. The even-skipped 3′ untranslated region is required to maintain late stage protein expression in RP2 and a/pCC neurons, and appears to affect protein levels rather than mRNA levels. Additionally, a strong pairing-sensitive repression element was localized to the 3′ end of the locus, but was not found to contribute to efficient functional rescue.

Abstract:
The ‘maccullochi species group’ of rainbowfishes are small and distinctly patterned freshwater fishes of streams and swamps, comprising around eight species. The species from which the group bears its name, Melanotaenia maccullochi Ogilby, 1915, has been thought to comprise three forms occurring in distinct geographic areas, and recent mitochondrial genetic data provides matching patterns of likely inter-specific divergence. Here we undertake a detailed investigation of the taxonomic status of M. maccullochi using a combined lines of evidence approach incorporating multiple nuclear genetic markers (55 allozyme loci), mitochondrial DNA sequence data (1141 bp cytochrome b) and morphology (examination of a suite of 38 morphometric and meristic characters). As all three datasets provide support for a three-way split, we accordingly describe two new species and redescribe M. maccullochi sensu stricto. McCulloch’s Rainbowfish M. maccullochi, a species with brown body stripes and red fins occurs in northeast Queensland and is redescribed based on 338 specimens, 13.1–53.0 mm SL. This species was one of the first rainbowfishes to become known in the aquarium hobby. A second form with darker stripes on a contrasting light white-grey body and with distinct sub-marginal black bands in the dorsal and anal fins, distributed across northern and eastern Cape York Peninsula, Torres Strait and southern central New Guinea, is described as Sahul Rainbowfish M. sahulensis sp. nov. based on 267 specimens, 13.4–48.4 mm SL. A diminutive and well geographically isolated form occurring below the escarpment of the Tabletop Range in Litchfield National Park, Northern Territory possessing a more prominent and purplish mid-lateral stripe, is described as the Little Rainbowfish Melanotaenia wilsoni sp. nov. based on 50 specimens, 19.3–33.3 mm SL. A combination of morphological characters is useful for separating the respective taxa with M. wilsoni sp. nov. the most distinctive, typically having fewer vertebrae, lateral scales, cheek scales, procurrent caudal rays and anal rays and proportionally a shorter maxilla and snout than either of the other two species. Useful characters for further separating M. sahulensis sp. nov. from M. maccullochi include slightly higher counts of vertebrae, lateral scales and anal rays and proportionally greater body depth, body width and pre-dorsal distance. Information on the known distribution, habitats and conservation status of the three species is summarised, with the Northern Territory species being a narrow-range endemic with specific environmental requirements.

Abstract:
Corcyrogobius pulcher sp. nov. is described from off Île de Ngor, Dakar, Senegal. Corcyrogobius pulcher is distinguished from its two congeners by having the rear edge of the jaws ending posteriorly below mideye, second dorsal fin I/9, pectoral fin rays 17, pelvic fins oval or truncated posteriorly, scales in lateral series 26–27, anterior oculoscapular head canal with pore β, suborbital row b of sensory papillae anteriorly beginning below vertical of posterior edge of eye, dark vertical caudal bar, branchiostegal membrane without intense dark spot, cheek with two oblique whitish stripes, the first going from the eye downwards and forward to the posterior jaws, the second on the preopercular, alternating with brown oblique stripe going from behind the eye downwards and forward across the cheek. Furthermore, mitochondrial COI-barcoding data unambiguously support the species-level distinctiveness of the three Corcyrogobius species. A key to the species of Corcyrogobius is provided.

Abstract:
Nothobranchius nikiforovi, a new species known from seasonal habitats in the lower Matandu drainage in south-eastern coastal Tanzania is described. It is distinguished from all other congeners, except N. eggersi, by males presenting two colour phenotypes: the blue phenotype having a bright iridescent light blue to blue-green body, with narrow red-brown scale margins creating irregular reticulated pattern, forming chevron-shaped crossbars on the posteroventral portion of body and light blue median fins with red-brown dotted pattern; the red phenotype has a dark red head, light blue dorsal and anal fins proximally and medially, dark red distally, with dark red stripes parallel to the fin rays, and a plain dark red caudal fin. Nothobranchius nikiforovi differs from N. eggersi by male colour pattern, the blue phenotypes having median fins with dark grey distal portion, some of the rays of dorsal and anal fins with white tips (vs. median fins with distinct slender white distal band), and the caudal fin lacking a spotted pattern (vs. dots arranged into irregular curved stripes); the red phenotype with golden stripe between the nape and dorsal-fin origin (vs. light-blue stripe), the dorsal and anal fins with a plain red distal portion and lacking a light distal band (vs. with distinct narrow white distal band), the pelvic fin lacking a distal band (vs. with distinct slender light blue to white distal band), and some morphometric differences. Phylogenetic analyses also support the genetic distinction of the new species from its closest known relative, N. eggersi, and confirm its position in the N. guentheri species group within the Adiniops subgenus.

Abstract:
The human visual system uses a-priori constraints for the estimation of surface shape from images. We propose here a robust paradigm to study individual observers' assumptions about the illuminant and viewpoint positions. In the study of illumination, the stimuli consisted of parallel, sinusoidally shaped, striped regions, alternating between wide and narrow. Narrow stripes alternating between white and black separated the uniform grey stripes, representing slanted edges in light and in shadow. The stimulus had the shape-from-shading ambiguity: either the wide or the narrow stripes could be seen as ‘in-front’, consistent with different assumed tilts of the illuminant. In a brief flash of a randomly oriented stimulus, observers stated whether the narrow or wide stripes appeared in the foreground. The results showed a strong bias for a light-from-above-left assumption (as in Howard et al, 1990 Perception19 523 – 530; Sun and Perona, 1996 Investigative Ophthalmology and Visual Science37 935). This bias was 20 to 30 deg to the left of vertical. Slower reaction times were obtained for more ambiguous figures. The same shape judgment task was used with an unshaded stimulus where the only depth cue was image contour. The same curvy, striped figure was portrayed with image contours at the edges of the stripes, as well as surface markings orthogonal to the depth variation, resulting in a shape-from-contour cue. We have previously reported indirect evidence for a bias of viewpoint above the object, that is observers interpret surface normals as pointing upward (Mamassian, 1995 Perception24 Supplement, 35). Our observers' shape judgments were consistent with this bias.

Abstract:
even-skipped (eve) has been proposed to set up parasegment borders at the anterior edge of each of its seven stripes by providing a sharp expression boundary, where engrailed is activated on one side and wingless on the other. By expressing bell-shaped early eve stripes without the sharp boundary provided by narrow, late stripes, we find that the early gradient is sufficient for generating stable parasegment borders. Based on several lines of evidence, we propose that the anterior portion of each early stripe has morphogenic activity, repressing different target genes at different concentrations. These distinct repression thresholds serve to both limit and subdivide a narrow zone of paired expression. Within this zone, single cell rows express either engrailed, where runt and sloppy-paired are repressed, or wingless, where they are not. While the early eve gradient is sufficient to establish parasegmental borders without refined, late expression, late eve expression has a role in augmenting this boundary to provide for strong, continuous stripes or engrailed expression. In addition, we show that the early eve gradient is sufficient, at its posterior edge, for subdividing the ftz domain into engrailed expressing and non-expressing cells.

Abstract:
Glyptothorax gopii, a new sisorid catfish, is described from the Kaladan River drainage in Mizoram, northeast India. It is distinguished from its congeners in the Indian subcontinent by the combination of the following characters: an axe-shaped anterior nuchal plate element extensively in contact with the posterior nuchal plate, plicae present on the ventral surfaces of the pectoral-fin spine and outer rays of pelvic-fin rays, an elliptical thoracic adhesive apparatus, the nasal barbel not reaching the anterior margin of the eye, tuberculate skin, and two pale cream longitudinal stripes on the body. Glyptothorax alaknandi is considered a valid species.

Abstract:
L'International Technology Roadmap for Semiconductors a identifié les dispositifs à base d'ondes de spin comme une alternative à la technologie CMOS pour les dispositifs logiques. Cependant, les dispositifs standards souffrent de plusieurs inconvénients liés à la miniaturisation et n'offrent pas la possibilité d'aborder le domaine des dispositifs logiques entièrement reprogrammables. L'objectif de ma thèse est d'établir une nouvelle voie vers des dispositifs logiques évolutifs et reprogrammables. Cette voie repose sur la stabilisation de domaines magnétiques périodiques rectilignes dont l’orientation peut être configurée à souhait pour ouvrir ou fermer le canal de transmission de l’information. Ce canal sera formé dans un matériau à faible amortissement pour une propagation des ondes de spin sur des distances microniques. D’une part, des domaines magnétiques de type Weak Stripes ont été obtenus dans l’alliage Co₄₀Fe₄₀B₂₀. Nous avons montré que ces domaines sont facilement orientables, ce qui permettra de facilement ouvrir ou fermer le canal de transmission des ondes de spin. Un amortissement inférieur à 7.10⁻³ peut être obtenu. La microscopie magnétique nous a permis de déterminer l’angle de l’aimantation dans les bandes, sa distribution spatiale ainsi que sa variation sous champ magnétique. De plus, nous avons montré pour la première fois la configuration de surface de ces Weak Stripes, configuration en accord avec les simulations micromagnétiques. D’autre part, des domaines magnétiques de type Strong Stripes sont obtenus dans les multicouches [Co/Ni]n. Leurs propriétés sont proches de celles observées dans d’autres matériaux comme le Co épitaxié. Un coefficient d’amortissement inférieur à 8.8 ×10⁻³ est obtenu, parmi les plus petits pour des systèmes à aimantation perpendiculaire. Leurs propriétés magnétiques microscopiques montrent que l’orientation des bandes est plus difficile à obtenir à cause d’une transformation bandes/bulles non encore répertoriée dans la littérature
The International Technology Roadmap for Semiconductors has identified spin wave devices as an alternative to CMOS technology for logic devices. The interest of these emerging devices lies in the scalability needed to process the ever-increasing amount of data generated by our information and communication society while maintaining low power consumption. However, standard devices suffer from drawbacks related to miniaturization and do not offer the possibility to enter the field of fully reprogrammable logic devices. The objective of my thesis is to establish a new path towards scalable and reprogrammable logic devices. This path is based on the stabilization of rectilinear periodic magnetic domains whose orientation can be configured to open or close the transmission channel. This channel will be formed in a low-damping material for spin wave propagation over micron distances. On one hand, magnetic domains of the Weak Stripes type have been obtained in the Co₄₀Fe₄₀B₂₀ alloy. We have shown that these domains are easily orientable, which will allow to easily open or close the transmission channel of spin waves. We show that a damping lower than 7×10⁻³ can be obtained. Magnetic microscopy allowed us to determine the angle of magnetization in the stripes, its spatial distribution as well as its variation under magnetic field. In addition, we show for the first time the surface configuration of these Weak Stripes, a configuration in accordance with the micromagnetic simulations. On the other hand, Strong Stripes magnetic domains are obtained in the [Co/Ni]n multilayers. Their properties are close to those observed in other materials such as Co epitaxial films. A damping coefficient lower than 8.8 ×10⁻³ is obtained, among the smallest for perpendicular magnetization systems. The study of their microscopic magnetic properties shows that the orientation of straight domains is more difficult to obtain because of a stripe/bubble transformation which has not yet been documented in the literature

Abstract:
Superstring theory is one current, promising attempt at unifying gravity with the other three known forces: the electromagnetic force, and the weak and strong nuclear forces. Though this is still a work in progress, much effort has been put forth toward this goal. A set of specific tools which are used are gauge/gravity dualities. This thesis consists of a specific implementation of gauge/gravity dualities to describe k-strings of strongly coupled gauge theories as objects dual to Dpbranes embedded in confining supergravity backgrounds from low energy superstring field theory. Along with superstring theory, k-strings are also commonly investigated with lattice gauge theory and Hamiltonian methods. A k$string is a colorless combination of quark-anti-quark source pairs, between which a color flux tube develops. The two most notable terms of the k-string energy are, for large quark anti-quark separation L, the tension term, proportional to L, and the Coulombic 1/L correction, known as the Luscher term. This thesis provides an overview of superstring theories and how gauge/gravity dualities emerge from them. It shows in detail how these dualities can be used for the specific problem of calculating the k-string energy in 2+1 and 3+1 space-time dimensions as the energy of Dp-branes in the dual gravitational theory. A detailed review of k-string tension calculations is given where good agreement is found with lattice gauge theory and Hamiltonian methods. In reviewing the k-string tension, we also touch on how different representations of k-strings can be described with Dp-branes through gauge/gravity dualities. The main result of this thesis is how the Luscher term is found to emerge from the energy calculation of Dp-branes. In 2+1 space-time dimensions, we have Luscher term data to compare with from lattice gauge theory, where we find good agreement.

Abstract:
One of the most interesting problems in string theory is to understand how the background space-time on which the string propagates arises in a self-consistent way. For open strings, there are two main approaches to this problem, boundary string field theory (BSFT) and cubic string field theory (CSFT). In the first part of this Thesis we deal with the construction of the spacetime tachyon effective action in BSFT. Renormalization fixed points are solutions of classical equations of motion and should be viewed as solutions of classical string field theory. We have constructed the Witten-Shatashvili (WS) space-time action S and shown that some solitonic solutions are lower dimensional D-branes for which the finite value of S provides a quite accurate prediction of the D-brane tension. We have derived the explicit relation between the CSFT and WS action as a field redefinition which is nonsingular on-shell only when the normalization factor in the WS action coincides with the tension of the D25-brane, in agreement with the conjectures involving tachyon condensation. We have also found a time-dependent solution of CSFT whose evolution is driven by a diffusion equation that makes the equations of motion local with respect to the time variable. The analysis here proposed has attracted a good deal of attention for its potential cosmological applications. The profile can be expressed in terms of a series in powers of exponentials of the time coordinate, and gives evidence of a well-defined but wildly oscillatory behavior. The tachyon rolls well past the minimum of the potential, then turns around and begins to oscillate with ever increasing amplitude. Furthermore, we have derived an analytic series solution of the elliptic equations providing the 4-tachyon off-shell amplitude. From such a solution we computed the exact coefficient of the quartic effective action relevant for time-dependent solutions and we derived the exact coefficient of the quartic tachyon coupling. We studied the rolling tachyon solution expressed as a series of exponentials of the time coordinate both using level-truncation computations and the exact 4-tachyon amplitude. The results for the level-truncated coefficients converge to those derived using the exact string amplitude and confirm the wild oscillatory behavior. In the second part of the Thesis we consider the extension of the gauge/gravity correspondence to systems with reduced and hence more realistic supersymmetry, which is one of the main steps towards a non-perturbative description of confining, QCD-like, gauge theories in terms of gravitational backgrounds. If string theory on AdS5xS5 is integrable, the theory on simple orbifolds of that space would also be expected to be integrable. We have computed the planar finite size corrections to the spectrum of the dilatation operator acting on states of a certain limit of conformal N = 2 quiver gauge field theory which is a ZM-orbifold of N = 4 SYM theory. We matched the result to the string dual, IIB superstrings on a pp-wave background with a periodically identified null coordinate. Up to two loops, we have shown that the computations done by using an effective Hamiltonian technique and a twisted Bethe Ansatz agree with each other and also agree with a computation of the analogous quantity in string theory. Our results are consistent with integrability of the N = 2 theory.

Abstract:
Thesis (D.M.A.)--Boston University
This study examines the pedagogical content knowledge of music teachers who teach in or out of their field of expertise. The primary goal of this study was to observe string specialists' and non-string specialists' content knowledge, pedagogical knowledge, and the instructional strategies used to teach vibrato, shifting, and spiccato bowing technique in an intermediate string class. The study provided an in-depth understanding of string specialists' and non-string specialists' (a) content knowledge of vibrato, shifting, and spiccato bowing; (b) content and pedagogical knowledge to teach vibrato, shifting, and spiccato bowing technique; and (c) how pedagogical content knowledge is used to teach vibrato, shifting, and spiccato bowing technique. A multiple case study design was used to examine how pedagogical content knowledge was used by string specialists and non-string specialists to teach string-specific technique. A purposeful sample of 6 cases was selected for the study. String specialists and non-string specialists were purposefully chosen to understand how pedagogical knowledge is used to teach string-specific technique. In order to perform a cross-case analysis, similar cases (e.g., location, level, program size) were chosen. Data were collected through observations of rehearsals and interviews with string specialists and non-string specialists. Each participant was observed teaching three rehearsals, and three interviews were conducted with each participant. Through the coding process, emergent themes were explored to provide detailed insight into the pedagogical and content knowledge of string specialists and non-string specialists. Interview transcripts were coded using WEFT QDA 1.01 software (Fenton, 2006). The findings suggest that non-string specialists in this study have a limited understanding of the fundamental general principles for vibrato, shifting, and spiccato bowing technique. The non-string specialists' content knowledge of vibrato, shifting, and spiccato bowing had more misconceptions, more misunderstandings, and a less organized understanding of the content when compared to string specialists. Additionally, non-string specialists with limited content knowledge chose less challenging instructional strategies than string specialists. This research will help to inform the string profession regarding the importance of string-specific content knowledge and pedagogical strategies, and assist non-string specialists who teach string classes in better understanding the knowledge and approaches they might presently be lacking.

Abstract:
A basic attribute for turbine blade film cooling is that coolant injected should be largely passively convected by the local base flow. However the effective working of the conventional wisdom may be compromised when the cooling injection strongly interacts with the base flow. Rotor blade tip of a transonic high-pressure (HP) turbine is one of such challenging regions for which basic understanding of the relevant aerothermal behavior as a basis for effective heat transfer/cooling design is lacking. The need to increase our understanding and predictability for high speed transonic blade tip has been underlined by some recent findings that tip heat transfer characteristics in a transonic flow are qualitatively different from those at a low speed. Although there have been extensive studies previously on squealer blade tip cooling, there have been no published experimental studies under a transonic flow condition. The present study investigates the effect of cooling injection on a transonic squealer tip through a closely combined experimental and CFD effort. The experimental and computational results as presented in Part 1 have consistently revealed some distinctive aerothermal signatures of the strong coolant-base flow interactions. In this paper as Part 2, detailed analyses using the validated CFD solutions are conducted to identify, analyze and understand the causal links between the aerothermal signatures and the driving flow structures and physical mechanisms. It is shown that the interactions between the coolant injection and the base Over-Tip Leakage (OTL) flow in the squealer tip region are much stronger in the frontal subsonic region than the rear transonic region. The dominant vortical flow structure is a counter-rotating vortex pair (CRVP) associated with each discrete cooling injection. High HTC stripes on the cavity floor are directly linked to the impingement heat transfer augmentation associated with one leg of the CRVP, which is considerably enhanced by the near-floor fluid movement driven by the overall pressure gradient along the camber line. The strength of the coolant-base flow interaction as signified by the augmented values of the HTC stripes is seen to correlate to the interplay and balance between the OTL flow and the CRVP structure. As such, for the frontal subsonic part of the cavity, there is a prevailing spanwise inward flow initiated by the CRVP, which has profoundly changed the local base flow, leading to high HTC stripes on the cavity floor. On the other hand, for the rear high speed part, the high inertia of the OTL flow dominates, thus the vortical flow disturbances associated with the CRVP are largely passively convected, leaving clear signatures on the top surface of the suction surface rim. A further interesting side-effect of the strong interaction in the frontal subsonic region is that there is considerable net heat flux reduction in an area seemingly unreachable by the injected coolant. The present results have confirmed that this is due to the large reduction in the local HTC as a consequence of the upstream propagated impact of the strong coolant-base flow interactions.

Abstract:
Photorefractive spatial solitons [1-3] are promising for applications in all-optical switching, optical interconnects and the development of novel photonic devices. We report on study of steady-state dark photorefractive screening-solitons, formed when a laser beam containing a dark notch propagates through a bulk strontium barium niobate crystal biased by an electric field. A dark photorefractive soliton, although generated with a weak beam, induces a waveguide in the bulk of the crystal that guides other strong beams of longer wavelengths. Fundamental, Y-Junction and multiple dark photorefractive solitons are observed, so are the waveguides they induce that can guide other beams into multiple channels [3]. A dark photorefractive soliton can also couple with another dark or bright soliton, forming interesting coupled spatial soliton pairs that consist of self-guided propagation of two beams in the photorefractive materials [4]. Recently, we have demonstrated steady-state self-trapping of circular and elliptical optical vortices (in both transverse dimensions) due to two distinctly different nonlinear mechanisms: the bulk photovoltaic effect in an unbiased LiNbO3 crystal, and the photorefractive screening effect in a biased SBN crystal [5].

Abstract:
We report the first experimental observation of a progression of allowed eigenmodes in a 10-element gain-guided diode laser array. By injection-seeding the array using the single-frequency output from a tunable cw dye laser, a sequence of eigenmodes of order 1–15 are selectively excited as the injected frequency is increased. Our results, in the form of observed near- and far-field intensity distributions emitted from these arrays, provide strong corroborative evidence for a model that views these devices as spatially gain-perturbed broad-area lasers whose characteristics are dominated by plane-wavelike interactions.1,2 Consistent with this picture we find that lower-order (v < 10) modes can only be excited by optically injecting the entire width of the device. In contrast, the higher-order (v ≥ 10) modes, which exhibit larger tilts in their emission phase fronts with respect to the resonator axis, are more strongly coupled across the gain stripes of the device. These are thus easily excited by injecting the proper frequency radiation into a small region (≤ 5 μm) near the center of the array. From these studies the highest-gain eigenmodes are seen to be those for which v = 10 or 11. Indeed, these modes have been observed with the device operating in free-running conditions (i.e., no injection) near threshold. Our experimental results for both the free-running and injected arrays are compared to theory.

Abstract:
Dark solitons [1] have provoked much interest [2-7] since they were first shown to be particular solutions of the two-dimensional (1+1)-D nonlinear Schrödinger equation (NSE) with a negative (self-defocusing type) nonlinear coefficient n2 (see Eq. (1) below). So far, only (1+1)-D temporal dark solitons (i.e. intensity minimums propagating along a nonlinear fiber on a quasi-cw bright background) have been observed experimentally [4-7]. Here we report the first observations [8] of stable spatial structures (e. g., stripes, crosses and grids) in the transverse cross-section of a cw optical beam propagating in a material with a self-defocusing nonlinearity, with these structures having a strongly pronounced soliton nature — namely that of spatial dark solitons (SDS's). Although no (2+1)-D analytical solution for dark solitons in the NSE is known to date, our experimental and numerical data with various 2-D amplitude and phase masks provide strong evidence that the phenomenon observed by us is indeed due to spatial dark solitons. Furthermore, our results here on quasi-(1+1)-D propagation (see also [8,9]) have shown excellent agreement with the well known analytical results for (1+1)-D dark solitons [1]. In comparison to temporal dark solitons SDS's are easy to create and observe experimentally, requiring as little as a HeNe laser and some slightly absorbing fluid. Most recently, one of the authors (D.R.A.) with his coworkers have observed SDS's in pulse radiation in ZnSe crystals [10]. Various applications of SDS's can be envisioned, such as optical encoding, limiting, switching and computing, and nonlinear filtering.

Abstract:
Brine strings are essential components of both natural gas and liquid hydrocarbon storage caverns. Both the natural gas and liquid hydrocarbon storage industries are well aware that a limit exists for the fluid velocity in the injection tubulars in their storage caverns. If the brine injection or brine withdrawal velocity is gradually increased, eventually, the hanging tubular will experience flow-induced vibration, resulting in the potential for the hanging tubulars to bend and/or break. Additionally, in both types of hydrocarbon storage, salt falls can impact the brine string integrity.Result: The magnitude of the velocity limit for flow-induced vibration of the hanging tubulars in salt caverns is not known. In the absence of a clearly defined method for determining the maximum allowable fluid velocities in the hanging tubulars, much of industry has attempted to adopt a conservative maximum flow velocity based on "industry experience". Sometimes this works and sometimes it does not. The objective of this project is to better define the causes of brine string failure and failure mitigation technologies. The project (1) compiled case histories of successful brine string installations as well as brine string failures in solution mining, liquid hydrocarbon storage, and gas cavern dewatering; (2) evaluated case histories with models (proposed in the literature) for brine strings that have not failed as well as brine strings that have experienced failure; and (3) developed recommendations for maximizing brine string integrity.
