description: Using a dynamic variant of the Vicsek model, we show that emergence of a crush from an orderly moving human crowd is a non-equilibrium first order phase transition. We also show that this transition can be reversed by modifying the dynamics of a few people, deemed as game changers. Surprisingly, the optimal placement of these game changers is found to be in regions of maximum local crowd speed. The presence of such game changers is effective owing to the discontinuous nature of the underlying phase transition. Thus our generic approach provides (i) strategies to delay crush formation and (ii) paths to recover from a crush, two aspects that are of paramount importance in maintaining safety of mass gatherings of people.

description: This work deals with the local rapid exponential stabilization for a Boussinesq system of KdV-KdV type introduced by J. Bona, M. Chen and J.-C. Saut. This is a model for the motion of small amplitude long waves on the surface of an ideal fluid. Here, we will consider the Boussinesq system of KdV-KdV type posed on a finite domain, with homogeneous Dirichlet--Neumann boundary controls acting at the right end point of the interval. Our goal is to build suitable integral transformations to get a feedback control law that leads to the stabilization of the system. More precisely, we will prove that the solution of the closed-loop system decays exponentially to zero in the $L^2(0,L)$--norm and the decay rate can be tuned to be as large as desired if the initial data is small enough.

description: Two major structural styles are identified in the Wilcox growth-fault trend of the Texas Gulf Coast. The style in central and southeast Texas is characterized by continuous, closely spaced growth faults that have little associated rollover despite moderate expansion of section and that show little flattening of the fault plane with depth. Where the growth-fault trend crosses the Houston Diapir Province, growth faults are localized by preexisting salt pillows; however, the piercement salt domes formed after the main phase of faulting, so the salt tectonics "overprints" the growth faults. In South Texas (south of Live Oak County), a narrow band of growth faults having high expansion and moderate rollover lies over and downdip of a ridge of deformed, overpressured shale and lies updip of a deep Tertiary-filled basin formed by withdrawal of overpressured shale. Significant antithetic faulting is associated with this band of growth faults. Also in South Texas, the lower Wilcox Lobo trend is deformed by highly listric normal faults beneath an unconformity that is probably related to Laramide tectonic activity. Wilcox sandstone reservoirs are predominantly of high-constructive deltaic (distributary-channel and delta-front) origin. This, together with close spacing of faults and characteristically low permeabilities, limits the size of geopressured reservoirs. The largest reservoirs may be in interfault areas or in salt- or shale-withdrawal basins.

description: After decades of molecular phylogenetic studies, the deep phylogeny of gymnosperms has not been resolved, and the phylogenetic placement of Gnetales remains one of the most controversial issues in seed plant evolution. To resolve the deep phylogeny of seed plants and to address the sources of phylogenetic conflict, we conducted a phylotranscriptomic study with a sampling of all 13 families of gymnosperms and main lineages of angiosperms. Multiple datasets containing up to 1 296 042 sites across 1308 loci were analysed, using concatenation and coalescence approaches. Our study generated a consistent and well-resolved phylogeny of seed plants, which places Gnetales as sister to Pinaceae and thus supports the Gnepine hypothesis. Cycads plus Ginkgo is sister to the remaining gymnosperms. We also found that Gnetales and angiosperms have similar molecular evolutionary rates, which are much higher than those of other gymnosperms. This implies that Gnetales and angiosperms might have experienced similar selective pressures in evolutionary histories. Convergent molecular evolution or homoplasy is partially responsible for the phylogenetic conflicts in seed plants. Our study provides a robustly reconstructed backbone phylogeny important for future molecular and morphological studies of seed plants, in particular gymnosperms, in the light of evolution.

description: Iron-based superconductors are well known for their complex interplay between structure, magnetism and superconductivity. FeSe offers a particularly fascinating example. This material has been intensely discussed because of its extended nematic phase, whose relationship with magnetism is not obvious. Superconductivity in FeSe is highly tunable, with the superconducting transition temperature, $T_\mathrm{c}$, ranging from 8 K in bulk single crystals at ambient pressure to almost 40 K under pressure or in intercalated systems, and to even higher temperatures in thin films. In this topical review, we present an overview of nematicity, magnetism and superconductivity, and discuss the interplay of these phases in FeSe. We focus on bulk FeSe and the effects of physical pressure and chemical substitutions as tuning parameters. The experimental results are discussed in the context of the well-studied iron-pnictide superconductors and interpretations from theoretical approaches are presented.

description: The physical states on the free field Fock space of the ${SL(2,R)\over SL(2,R)$ model at any level are computed. Using a similarity transformation on $Q_{BRST}$, the cohomology of the latter is mapped into a direct sum of simpler cohomologies. We show a one to one correspondence between the states of the $k=-1$ model and those of the $c=1$ string model. A full equivalence between the ${SL(2,R)\over SL(2,R)$ and ${SL(2,R)\over U(1)$ models at the level of their Fock space cohomologies is found.

description: Two-qubit quantum codes have been suggested to obtain better efficiency and higher loss tolerance in quantum key distribution. Here, we propose a two-qubit quantum key distribution protocol based on a mixed basis consisting of two Bell states and two states from the computational basis. All states can be generated from a single entangled photon pair resource by using local operations on only one auxiliary photon. Compared to other schemes it is also possible to deterministically discriminate all states using linear optics. Additionally, our protocol can be implemented with today's technology. When discussing the security of our protocol we find a much improved resistance against certain attacks as compared to the standard BB84 protocol.

description: The threshold law for N-body fragmentation under dipole forces is formulated. It emerges from the energy dependence of the normalization of the correlated continuum wave function for N fragments. It is shown that the dipole threshold law plays a key role in understanding all threshold fragmentation phenomena since it links the classical threshold law for long-range Coulomb interactions to the statistical law for short-range interactions. Furthermore, a tunnelling mechanism is identified as the common feature which occurs for all three classes of interactions, short-range, dipole and Coulomb.

description: The electronic structure of interfaces between YBa$_2$Cu$_3$O$_6$ and SrTiO$_3$ is studied using local spin density approximation (LSDA) with intra-atomic Coulomb repulsion (LSDA+U). We find a metallic state in cuprate/titanate heterostructures with the hole carriers concentrated substantially in the CuO$_2$-layers and in the first interface TiO$_2$ and SrO planes. This effective interface doping appears due to the polarity of interfaces, caused by the first incomplete copper oxide unit cell. Interface-induced high pre-doping of CuO$_2$-layers is a key mechanism controlling the superconducting properties in engineered field-effect devices realized on the basis of cuprate/titanate superlattices.

description: The Miocene Major Stratigraphic Unit (MSU) of the Texas Coastal Plain is an offlapping sedimentary sequence deposited over the continental platform constructed by Late Oligocene Frio progradation. These Miocene deposits have yielded nearly 3 billion bbl of oil and 7 trillion ft3 of gas. Correlations with mammalian and foraminifer zones indicate that the Miocene MSU and its updip equivalents, the Oakville and Lagarto Formations (Fleming Group), range in age from Early to Late Medial Miocene (22.5 to 12 m.y.a.). Downdip, the upper Heterostegina and Discorbis Zones of the Anahuac shale wedge are included as a part of the Miocene MSU. Regional subsurface study indicates division of the Miocene MSU into six principal depositional systems: the Cypress fluvial system and San Jacinto delta system, developed in the Houston Embayment; the Moulton streamplain and Indianola barrier-strandplain-lagoon system across the San Marcos Arch; and the Santa Cruz fluvial system and Rosita delta system located in the Rio Grande Embayment. Integration of regional studies of depositional systems, their facies suites, structural styles, and character of produced hydrocarbons permitted delineation of 10 hydrocarbon production-exploration plays. The play forms the basic analytical unit in characterization of hydrocarbon production histories, predictions of future discoveries, and the placement of potential resources in a geographic-stratigraphic context. The Miocene MSU lacks entirely, or contains only negligible volumes of thermally mature source rocks. Thus, all Miocene MSU hydrocarbons are exotic, having been derived either by upward migration from older formations, or by lateral, updip migration from offshore marine Miocene units. Based on three historical evaluation methods employed in this study, the Miocene MSU contains between 250 and 1360 million boe of undiscovered, conventionally producible hydrocarbons.

Magnetic Fields and the Triaxiality of Molecular Cloud Cores
Creators: name: Basu, Shantanu
Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We make the hypothesis that molecular cloud fragments are triaxial bodies with a large scale magnetic field oriented along the short axis. While consistent with theoretical expectations, this idea is supported by magnetic field strength data, which show strong evidence for flattening along the direction of the mean magnetic field. It is also consistent with early submillimeter polarization data, which show that the projected direction of the magnetic field is often slightly misaligned with the projected minor axis of a molecular cloud core, i.e., the offset angle $Ψ$ is nonzero. We calculate distributions of $Ψ$ for various triaxial bodies, when viewed from a random set of viewing angles. The highest viewing probability always corresponds to $Ψ=0^{\circ}$, but there is a finite probability of viewing all nonzero $Ψ$, including even $Ψ=90^{\circ}$; the average offset typically falls in the range $10^{\circ}-30^{\circ}$ for triaxial bodies most likely to satisfy observational and theoretical constraints.

description: Significant progress has been achieved in Computer Vision by leveraging large-scale image datasets. However, large-scale datasets for complex Computer Vision tasks beyond classification are still limited. This paper proposed a large-scale dataset named AIC (AI Challenger) with three sub-datasets, human keypoint detection (HKD), large-scale attribute dataset (LAD) and image Chinese captioning (ICC). In this dataset, we annotate class labels (LAD), keypoint coordinate (HKD), bounding box (HKD and LAD), attribute (LAD) and caption (ICC). These rich annotations bridge the semantic gap between low-level images and high-level concepts. The proposed dataset is an effective benchmark to evaluate and improve different computational methods. In addition, for related tasks, others can also use our dataset as a new resource to pre-train their models.

description: Information, like gold, is where you find it. Geological information is no exception, but in Texas such data are often readily at hand. The state has one of the highest concentrations of practicing geologists per capita in the United States; and Texans in general are very conscious of the importance of fossil fuels, earth materials, and land and water resources in the state's economy, history, and quality of life. But where does one turn for specific geological information? Fortunately, there are many sources of information on the geology of Texas, including: 1) State agencies 2) Federal agencies 3) Colleges and universities 4) Geological (and related) societies 5) Museums and nature centers 6) Oil, mining, and consulting companies 7) Public schools 8) Public libraries These organizations can often provide published information, films, lectures, and professional advice to persons requiring particular information as well as those who simply have a sincere interest in the geosciences. Most of the state and federal agencies, colleges and universities, and geological societies that engage in studies of the geology of Texas are listed in the accompanying appendices (A, B, C, and D), along with their addresses, telephone numbers, and summary statements of their areas of involvement or expertise.

description: A physical interpretation is given for some Hermitian Jordan triple systems (HJTS) that were recently discussed by Gunaydin (hep-th/9301050). Quadratic Jordan algebras derived from HJTS provide a formulation of quantum mechanics that is a natural framework within which exceptional structures are identified with physically realistic structures of a quantum field theory that includes both the standard model and MacDowell-Mansouri gravity. The structures allow the calculation of the relative strengths of the four forces, including the fine structure constant ALPHA = 1/137.03608.

description: The Palo Duro Basin is one of a dozen or more intracratonic basins formed as a result of large-scale plate motions in the Late Paleozoic (Goldstein, 1981; Kluth and Coney, 1981). The margins of the basin are defined by a series of uplifts that developed during the Pennsylvanian (fig. 1). The Palo Duro Basin is bounded on the northeast by the Amarillo-Wichita Uplift, on the northwest by the Bravo Dome, and on the west by the Sierra Grande and other smaller uplifts, all of which were important sources of sediment. To the south, the Matador Arch served as a sediment barrier and locus of carbonate buildups, as did a number of smaller, generally unnamed, uplifts to the east. The Palo Duro Basin includes sediments deposited in two temporally separate but spatially overlapping basins (Budnik and Smith, 1982). The initial basin, a northwest extension of the Hardeman Basin (fig. 2), formed as a result of the foundering of a Mississippian shelf during the latest Mississippian or early Pennsylvanian (Budnik and Smith, 1982; Dutton and others, 1982). Up to 2,500 ft (750 m) of Pennsylvanian and a similar thickness of Wolfcampian (Lower Permian), primarily marine, sediments were deposited during this phase (Dutton and others, 1982). A second basin (effectively the northern shelf of the Midland Basin; fig. 3) formed in response to regional subsidence of the much larger Permian Basin. In excess of 4,000 ft (1,200 m) of restricted marine to non-marine sediments were deposited nearly continuously throughout the mid- and late Permian (Leonardian, Guadalupian, and Ochoan; Presley, 1980).

description: Phytochemical investigation of the trunks from Gnetum latifolium led to the isolation of a novel phenolic glucoside, 2E-2,4-di-(3,4-dihydroxyphenyl)but-2-en-1-yl-O-β-D-glucopyranoside (1), along with five known stilbene derivatives (2–6). Their structures were determined mainly using high-resolution electrospray ionisation mass spectrometry and nuclear magnetic resonance spectroscopic analyses, followed by comparisons of observed spectral data with reported values. The novel compound 1 in G. latifolium was found to be useful as a chemotaxonomic marker. Biological evaluation revealed that compound 6 had remarkable inhibitory effects on nitric oxide production, with a half-maximal inhibitory concentration (IC50) value of 4.85 ± 0.20 µM, which was much higher than that of the positive control dexamethasone (IC50 = 14.20 ± 0.54 µM).

description: We provide a catalog for the effects of the human kinome on cell survival in response to DNA-damaging agents, covering all major DNA repair pathways. By treating 313 kinase-deficient cell lines with ten diverse DNA-damaging agents, including seven commonly used chemotherapeutics, we identified examples of vulnerability and resistance that are kinase specific. To investigate synthetic lethal interactions, we tested the response to carmustine for 25 cell lines by establishing a phenotypic fluorescence-activated cell sorting (FACS) assay designed to validate gene-drug interactions. We show apoptosis, cell cycle changes, and DNA damage and proliferation after alkylation- or crosslink-induced damage. In addition, we reconstitute the cellular sensitivity of DYRK4, EPHB6, MARK3, and PNCK as a proof of principle for our study. Furthermore, using global phosphoproteomics on cells lacking MARK3, we provide evidence for its role in the DNA damage response. Our data suggest that cancers with inactivating mutations in kinases, including MARK3, are particularly vulnerable to alkylating chemotherapeutic agents.

description: Joints are fractures in a rock that exhibit no detectable displacement between one face of the fracture and the other. Previous work on the origin of joints has determined different mechanisms to explain fracturing. Some researchers have explained joints in terms of their relationship to tectonic deformation and major structural elements (Harris and others, 1960; Price, 1966; Stearns and Friedman, 1972). Others have shown that joints may develop independently from tectonic deformation and that joints may form in sedimentary rocks early in their history (Parker, 1942; Hodgson, 1961; Price, 1966; Cook and Johnson, 1970). Price (1974) investigated the development of joints and stress systems in undeformed sediments during the accumulation of a sedimentary series, its downwarping and subsequent uplift, and accompanying de-watering of the sediments. Joints can also result from unloading due to erosion (Chapman, 1958). The formation of joints in sedimentary rocks is dependent on three factors (Hobbs, 1967): (1) physical properties of both the fractured rock bed and the surrounding rock beds; (2) thickness of the rock bed; and (3) degree of tectonic deformation of the beds.

description: This paper is about the fractional Schrödinger equation (FSE) expressed in terms of the quantum Riesz-Feller space fractional and the Caputo time fractional derivatives. The main focus is on the case of time independent potential fields as a Dirac-delta potential and a linear potential. For such type of potential fields the separation of variables method allows to split the FSE into space fractional equation and time fractional one. The results obtained in this paper contain as particular cases already known results for FSE in terms of the quantum Riesz space fractional derivative and standard Laplace operator.

These results point out on the possibility of existing in resonant cavities the new type of eigen oscillations based on the evanescent waves. Such oscillations do not exist in the smooth waveguides. They have a longitudinal distribution of electromagnetic field with decreasing (increasing) dependence on the coordinate. We discuss the using of such oscillations for bunching and accelerating of electron beams.

Air entrainment through free-surface cusps

Year: 2000
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: In many industrial processes, such as pouring a liquid or coating a rotating cylinder, air bubbles are entrapped inside the liquid. We propose a novel mechanism for this phenomenon, based on the instability of cusp singularities that generically form on free surfaces. The air being drawn into the narrow space inside the cusp destroys its stationary shape when the walls of the cusp come too close. Instead, a sheet emanates from the cusp's tip, through which air is entrained. Our analytical theory of this instability is confirmed by experimental observation and quantitative comparison with numerical simulations of the flow equations.

Once the network has been generated each edge is assigned an i.i.d. weight modeling the passage time of a message along this edge. Then independently two vertices are chosen uniformly at random, a sender and a recipient, and all edges along the geodesic connecting the two vertices are coloured in red (in the case that both vertices are in the same component). In this article we prove local limit theorems for the coloured graph around the recipient in the spirit of Benjamini and Schramm. We consider the explosive regime, in which case the random distances are of finite order, and the Malthusian regime, in which case the random distances are of logarithmic order.

description: After decades of molecular phylogenetic studies, the deep phylogeny of gymnosperms has not been resolved, and the phylogenetic placement of Gnetales remains one of the most controversial issues in seed plant evolution. To resolve the deep phylogeny of seed plants and to address the sources of phylogenetic conflict, we conducted a phylotranscriptomic study with a sampling of all 13 families of gymnosperms and main lineages of angiosperms. Multiple datasets containing up to 1 296 042 sites across 1308 loci were analysed, using concatenation and coalescence approaches. Our study generated a consistent and well-resolved phylogeny of seed plants, which places Gnetales as sister to Pinaceae and thus supports the Gnepine hypothesis. Cycads plus Ginkgo is sister to the remaining gymnosperms. We also found that Gnetales and angiosperms have similar molecular evolutionary rates, which are much higher than those of other gymnosperms. This implies that Gnetales and angiosperms might have experienced similar selective pressures in evolutionary histories. Convergent molecular evolution or homoplasy is partially responsible for the phylogenetic conflicts in seed plants. Our study provides a robustly reconstructed backbone phylogeny important for future molecular and morphological studies of seed plants, in particular gymnosperms, in the light of evolution.

description: The High Plains test site (fig. 1) is one of five areas selected in the State of Texas as part of the Applications System Verification and Transfer (ASVT) Project of the Texas Natural Resources Information System (TNRIS). This test site was chosen because the Texas Department of Water Resources (TDWR) needed timely information regarding water usage for irrigation in northwest Texas. The Test Plan for this project (Finley and Baumgardner, 1981) identified three objectives for the study of this test site: (1) identification of irrigated cropland, (2) definition of the spectral signature of drought-stressed vegetation, and (3) identification of broad crop categories. This report presents the results of work on the first objective, identification of irrigated cropland.
Even longer baselines: feasibility and observational implications

Publisher: name: Zenodo
Year: 2019

description: ALMA's high spatial resolution capabilities, provided by baselines of up to 16km length, have revolutionised observational millimeter/sub-millimeter astronomy. Although challenging in many respects, observations with the longest construction baselines have been highly successful. Offering even longer baselines is an axis of development supported for exploration by the ALMA 2030 Roadmap, but what are the possibilities for realistically achieving this, and what implications would there be on scientific observations? Here I will present the status of an ongoing ALMA development study investigating a simple baseline extension within the current operational model and with minimal technological changes. Results from a recent test campaign of interferometry between antennas at AOS and OSF sites (a 24km baseline with 2.2km altitude difference) will be presented. Beyond technical feasibility, the practicalities of locating new antenna stations, altitude differences and calibration will be discussed. The fundamental issue of surface brightness sensitivity for cool thermal emission (dust, thermal molecular lines) will be discussed, with a view to how this situation may develop in the scope of system upgrades supporting the 2030 Roadmap. Technically easier hot and non-thermal science cases such as the study of stellar photospheres and circumstellar masers will also be discussed.

description: We consider driven systems where the driving induces jumps in energy space: (1) particles pulsed by a step potential; (2) particles in a box with a moving wall; (3) particles in a ring driven by an electro-motive-force. In all these cases the route towards quantum-classical correspondence is highly non-trivial. Some insight is gained by observing that the dynamics in energy space, where $n$ is the level index, is essentially the same as that of Bloch electrons in a tight binding model, where $n$ is the site index. The mean level spacing is like a constant electric field and the driving induces long range hopping 1/(n-m).

description: Kriging is a statistical method historically used to estimate mineral reserves and more recently applied to estimate spatially-distributed or regionalized variables in hydrologic studies, such as ground-water fluid potential or transmissivity. In estimating these regionalized variables, kriging serves two main purposes. Firstly, it can generate a contour map of the variable with an associated measure of error. Secondly, it can optimize the location of additional samples, particularly valuable in acquiring data for ground-water potential in deep formations, which often involves drilling expensive wells. Kriging has been previously employed to estimate water elevation in studies such as those conducted at the Department of Energy Hanford Reservation in the Pasco Basin, Washington (Doctor, 1979), and in a study of the multilayer aquifer system underlying Venice, Italy (Volpi and Gambolati, 1979). In both cases, actual water level measurements were utilized. This report discusses the use of kriging methods by The University of Texas, Bureau of Economic Geology (UT/BEG), in the context of nuclear waste isolation feasibility studies in the Palo Duro Basin, funded by the Department of Energy under contract DE-AC97-80ET46615. Kriging has been employed by UT/BEG to estimate the ground-water potentiometric surfaces of the permeable San Andres cycle four dolomite and the Wolfcampian aquifer. The San Andres Formation study utilized water level measurements and drill-stem-test (DST) pressures. Kriging was applied to minimize the variation of the DST data and reveal the regional potentiometric surface. The Wolfcamp study relied solely on DST pressures, with kriging employed to model the variation in the data and generate a contoured map of the potentiometric surface. The kriging techniques employed by the Bureau of Economic Geology involve three steps: (1) variogram analysis, (2) kriging, and (3) contouring krige block estimates. Computer programs used for calculating the empirical variogram statistics, krige block estimates, and krige block variances were obtained from Dr. Young C. Kim and are detailed in Knudsen and Kim, 1978. For a comprehensive understanding of regionalized variables theory and kriging, please refer to Knudsen and Kim, 1978. A brief overview of the techniques used at the Bureau follows.
Cell Sequence and Mitosis Affect Fibroblast Directional Decision-Making during Chemotaxis in Tissue-Mimicking Microfluidic Mazes

description: Directed fibroblast migration is central to highly proliferative processes in regenerative medicine and developmental biology, such as wound healing and embryogenesis. However, the mechanisms by which single fibroblasts affect each other's directional decisions, while chemotaxing in microscopic tissue pores, are not well understood. Therefore, we explored the effects of two types of relevant social interactions on fibroblast PDGF-BB-induced migration in microfluidic tissue-mimicking mazes: cell sequence and mitosis. Surprisingly, it was found that in both cases, the cells display behavior that is contradictory to the chemoattractant gradient established in the maze. In case of the sequence, the cells do not like to take the same path through the maze as their predecessor, when faced with a bifurcation. To the contrary, they tend to alternate - if a leading cell takes the shorter (steeper gradient) path, the cell following it chooses the longer (weaker gradient) path, and vice versa. Additionally, we found that when a mother cell divides, its two daughters go in opposite directions (even if it means migrating against the chemoattractant gradient and overcoming on-going cell traffic). Therefore, it is apparent that fibroblasts modify each other's directional decisions in a manner that is counter-intuitive to what is expected from classical chemotaxis theory. Consequently, accounting for these effects could lead to a better understanding of tissue generation in vivo, and result in more advanced engineered tissue products in vitro.

description: Post-Aptian strata (younger than 112 Ma) in the East Texas Basin were strongly influenced by halokinesis and record the evolution of associated salt structures. Comparisons with model diapirs and dome-induced changes in patterns of sandstone distribution, depositional facies, and reef growth indicate that thickness variations in strata surrounding domes were caused by syndepositional processes rather than by tectonic distortion. Salt domes in the East Texas Basin exhibit three stages of growth: pillow, diapir, and post-diapir. Each stage affected surrounding strata differently. Pillow growth caused broad uplifting of strata over the crest of the pillows. The resulting topographic swells influenced depositional trends and were susceptible to erosion. Fluvial-channel systems bypassed pillow crests and stacked vertically in primary peripheral sinks on the updip flanks of the pillows. Diapir growth was characterized by expanded sections of shelf and deltaic strata in secondary peripheral sinks around the diapirs. Lower Cretaceous (Aptian) reefs on topographic saddles between secondary peripheral sinks now host major oil production at Fairway Field. Post diapir crestal uplifting and peripheral subsidence affected smaller areas than did equivalent processes that occurred during pillow or diapir stages. Pre-Aptian domes grew in three areas around the margin of the diapir province, apparently in pre-Aptian depocenters. Maximum dome growth along the basin axis coincided with maximum regional sedimentation there during the mid-Cretaceous (Aptian, Albian, and Cenomanian stages). In the Late Cretaceous, the sites of maximum diapirism migrated to the margin of the diapir province. Diapirism began after pillows were erosionally breached, which led to salt extrusion and formation of peripheral sinks.
