title: Sedimentology and Community Structure of Reefs of the Yucatan Peninsula, Mexico
Creators: name: Novak, Matthew J.
Publisher: name: Utah State University
Year: 1992

description: Holocene carbonate sediments from Mexican reefs in the Caribbean and Gulf of Mexico display variations in constituent composition, texture and mineralogy which are related to their locations on the reefs. Samples were collected at barrier reef environments at Akumal and Chemuyil, on the northeast coast of the Yucatan Peninsula; at the oceanic atoll of Chinchorro, off the southeast coast of the peninsula; and at the shelf atoll of Alacranes, in the Gulf of Mexico. Samples were collected through a depth range of 0-40 m, which encompasses back reef, shallow fore reef, and deeper fore reef environments.
Constituent-particle analysis of reef sediments indicates that lagoon facies are dominated by Halimeda with lesser amounts of coral and coralline algae. In contrast, fore reef facies are dominated by coral, with lesser amounts of Halimeda and coralline algae.
Greater than 90% of the sediments (dry weight) occur in the interval 0.125-2.00 mm, with mean grain sizes (Mz) approaching 0.5 mm at most sites. Mz generally decreases with increasing depth at three of the four sites. Reef sediments are moderately to poorly sorted and typically become more poorly sorted with increasing depth. Sediments collected from reef channels (grooves) are consistently better sorted than those from the reef interstices (spurs).
Mineralogically, the sediment is predominantly aragonite (63-93%) and high-Mg calcite (3-33%), with minor amounts of low-Mg calcite (3-9%). The sediment is chiefly composed of these three polymorphs of CaC03 (96.32- 99.83%) with only a small percentage of insoluble (non-carbonate) material. The non-carbonate fraction of the sediment is dominated by organics (0.14-3.16%) with lesser amounts of clay minerals and amorphous silica (0.00-0.66%).
Quantitative analysis of Mexican reef sediments in the Caribbean and Gulf of Mexico allows the delineation of reef zonations based on constituent-particle composition. Q-mode cluster analysis of constituent-particle data from epireefal sediments enables the separation of lagoon, shallow fore reef (10-15 m) lithofacies. These groupings were maintained even when constituent-particle data from the barrier reefs were combined, and also when data from the atoll reefs were combined. Similar cluster groupings were obtained when constituent-particle data from a Jamaican fringing reef were combined with data from the Mexican barrier reefs. This indicates that coastal reef sediments from Jamaica and Mexico are surprisingly similar in constituent-particle composition and facies zonations. However, cluster analysis failed to produce clear associations when constituent-particle data from barrier reefs and atoll reefs were combined. The sedimentological zonations observed in the study reflect the community composition of the living reefs, and indicate that community composition, at least for calcifying organisms, is potentially preservable.
title: Quaternary Geology and Neotectonics of Southern Star Valley and the Southwest Flank of the Salt River Range, Western Wyoming
Creators: name: Warren, Gregory A.
Publisher: name: Utah State University
Year: 1992

description: Southern Star Valley is a structural and physiographic basin bounded on the east by the southern Star Valley fault, an active normal fault associated with Basin and Range extension. The southern Star Valley fault separates southern Star Valley from the Salt River Range and forms a dramatic north-south trending topographic escarpment. Statistical analysis of relative-age dating (RD) parameters taken from glacial deposits in the Salt River Range defined distinctive age groups for the deposits, and comparison of RD data allowed correlations with late Pleistocene and Holocene glacial deposits elsewhere in the Rocky Mountains. However, the sedimentary lithologies in the glacial deposits in the study area and inherent variability of RD data limited definitive regional correlations.
The southern Star Valley fault (SSVF) lies in a parabola-shaped zone of large, seismogenic normal faults. The zone trails to the west of the eastward-migrating Yellowstone hot spot. Basin-facing fault scarps up to 11 meters high created by recurrent late Quaternary faulting along the southern Star Valley fault are preserved in late-Pleistocene and Holocene alluvial fans along the Salt River Range front.
Radiocarbon ages from faulted deposits exposed in a trench provide age estimates of ca. 8,090 ± 80 and 5,540 ± 70 yrs. B. P. for the two most recent paleoearthquakes. The magnitudes of the paleoearthquakes, based on surface rupture height and length and estimates, were between Ms6.9 and Ms7.1. The tectonic geomorphology of river alluvium and alluvial fans near the SSVF suggests that recurrent faulting has downdropped the northern end of southern Star Valley more in relationship to the southern part of the valley and created a deep depocenter in the northern part.

title: Quaternary Geology and Tectonic Geomorphology of the Pocatello Valley Area, Idaho-Utah
Creators: name: Garr, John D.
Publisher: name: Utah State University
Year: 1988

description: Pocatello Valley in southeastern Idaho and northern Utah is a structural and topographic basin bounded on all sides by mountains composed of Paleozoic platform carbonates and elastics. In the late Pleistocene it contained pluvial Lake Utaho, which, prior to 1981, was considered to have been an arm of Lake Bonneville. This study corroborates the finding of Currey (1981) that the two lakes were separate.
The Quaternary deposits examined in this study are divided into two broad groups: those that were deposited prior to the last pluvial lake cycle, and those that were deposited during and after the pluvial lake maximum, (since approximately 16 ka) when the area was occupied by Lake Utaho and Lake Bonneville. Pediment gravels, alluvial fans, piedmont colluvium, and talus comprise the older group: the younger deposits include stream channel deposits, lacustrine sediments, and loess.
Quantitative front sinuosity height ratios) geomorphological techniques (mountain ratios and valley floor width-valley indicate that the bounding ranges on the east and west margins of Pocatello Valley are slightly to moderately active tectonically. Precise surveying of the Lake Utaho highstand shoreline revealed significant deviations from the smooth, isostatically rebounded shoreline elevation curve of Crittenden (1963). The greatest deflections occur where the sinuous shoreline crosses the more linear inferred range front faults at the base of Samaria Mountain, on the east margin of the valley. The deflections (as much as 6.4 m over a horizontal distance of 900 m) suggest that movement has occurred along the range front faults since the shorelines were created approximately 16 ka, but no fault scarps were formed. A buried colluvium estimated to be 95 ka + 15 ka that was exposed draped toward in a over the trench at the range the inferred fault, valley. There are front is monoclinally and dips as much as 49° no fractures in the colluvium, which suggests that, although relative movement between the mountain and valley blocks has occurred, the displacement has only warped the colluvium. This further suggests that any earthquakes accompanying the movements must have been below the magnitude threshold (ML 6.2-6.3) necessary for surface rupture.

description: In this paper we examine a low-energy SEP event observed by IS$\odot$IS's Energetic Particle Instrument-Low (EPI-Lo) inside 0.18 AU on September 30, 2020. This small SEP event has a very interesting time profile and ion composition. Our results show that the maximum energy and peak in intensity is observed mainly along the open radial magnetic field. The event shows velocity dispersion, and strong particle anisotropies are observed throughout the event showing that more particles are streaming outward from the Sun. We do not see a shock in the in-situ plasma or magnetic field data throughout the event. Heavy ions, such as O and Fe were detected in addition to protons and 4He, but without significant enhancements in 3He or energetic electrons. Our analysis shows that this event is associated with a slow streamer-blowout coronal mass ejection (SBO-CME) and the signatures of this small CME event are consistent with those typical of larger CME events. The time-intensity profile of this event shows that PSP encountered the western flank of the SBO-CME. The anisotropic and dispersive nature of this event in a shockless local plasma give indications that these particles are most likely accelerated remotely near the Sun by a weak shock or compression wave ahead of the SBO-CME. This event may represent direct observations of the source of low-energy SEP seed particle population.

description: Higher-dimensional Thompson's groups nV are finitely presented groups described by Brin which generalize dyadic self-maps of the unit interval to dyadic self-maps of n-dimensional unit cubes. We describe some of the metric properties of higher-dimensional Thompson's groups. We give descriptions of elements based upon tree-pair diagrams and give upper and lower bounds for word length in terms of the size of the diagrams. Though these upper and lower bounds are somewhat separated, we show that there are elements realizing the lower bounds and that the fraction of elements which are close to the upper bound converges to 1, showing that the bounds are optimal and that the upper bound is generically achieved.

title: Spatial and Temporal Variations of the Pilot Valley Playa Interpreted From Remotely Sensed Images
Creators: name: Doremus, Llyn
Publisher: name: Utah State University
Year: 1992

description: In the Basin and Range Province, the geologic regime of the Pilot Valley, linear trending block faults have isolated many valleys both topographically and hydrologically. Discharge from these arid, closed basins occurs only as evaporation. Minerals dissolved in discharging fluid are precipitated at the valley floor as the liquid evaporates. The resulting salt flats and high density brines are known as playas.
The Pilot Valley Playa surface was sampled concurrently with the recording of a Thematic Mapper remotely sensed image to define the surface conditions that correspond to image data. An association was found between the band 7 (infrared wavelength radiation) image data and the measured depth to water; and between the visible wavelength data and the evaporite mineral deposits on the playa. The specific gravity of the shallow subsurface brine was found to increase as the liquid brine surface approached the elevation of the valley floor. By using the observed relationships, three remotely sensed images were interpreted with respect to temporal changes in the areal extent of playa evaporite deposits and water depth between 1984 and 1988. The visible wavelength data indicated that the areal extent of the evaporite deposits diminished during the study period. The water level at the playa margins was interpreted to have dropped, and at the playa center to have remained stable. These interpretations suggest that a decrease in the extent of evaporite deposition is related to a drop in the water level around the playa margins.
The interpreted changes of the playa surface are used to draw the following conclusions about the hydrology of the Pilot Valley. The distinct variation in depth to water around the playa margin suggests that these areas are influenced by the discharge from the surrounding ranges. The relatively stable water depth in the central playa and the associated thicker evaporite deposits suggest that the subsurface brine acts here as a buffer to discharge variations. If the temporal changes of the playa margins do result from discharge variation, the discharge zone at the base of the Silver Island Range is wider than that of the adjacent, higher elevation Pilot Range.

title: Laramide Deformation in Precambrian Granitic Rocks, Northeastern Wind River Range, Wyoming
Creators: name: DuBois, Mark A.
Publisher: name: Utah State University
Year: 1990

description: Fractures and faults in the Jakey's Fork area, northeastern Wind River Range, Wyoming, caused by brittle Laramide deformation in the Precambrian granitic basement have been studied in detail at airphoto, outcrop, and thin-section scales. The study area is bounded on the south by the approximately east-west and vertical Jakey's Fork Fault and on the east by the approximately northwest-southeast and vertical Ross Lakes Fault. Both were active during Laramide deformation. Four distinct structural domains, defined by fracture pat terns and proximity to the two major faults nave emerged in this study. The areas are: 1) Along Ross Lakes Fault granite cores a fold defined by shallowly and steeply east dipping Cambrian Flathead Sandstone. Laramide movement on Ross Lakes Fault appears to have post-dated, Jakey ' s Fork Fault movement and was discordant with Precambrian zones. Fractures at all scales studied strike approximately northeast-southwest, consistent with the inferred maximum Laramide principal stress. 2) Along east-west striking Jakey's Fork Fault, Laramide movement appears to have reactivated Precambrian mylonite zones as evidenced by the chlorite-rich, foliated cataclasite along its trace. Fractures at all scales have an approximate east-west orientation. 3) Near the intersection of the two faults, deformation was intense, as shown by mylonitic, breccia, and veined clasts. Discrete airphoto fractures were not recognized due to intense deformation in this interaction zone. 4) In the central area, away from the two faults, airphoto and outcrop fracture orientations have a north to northeast strike. Fracture orientations at the thin-section scale are more variable and do not agree with macroscopic orientations; they strike west to northwest. The central area is a 'block', possibly divided into 'sub-blocks' , bounded by zones along which much of the deformation occurred. Thus, these zones had an insulating effect at thin-section scale. The Paleozoic rocks were at least partially decoupled from the basement during deformation, suggested by gouge along the contact and different fracture orientations on opposite sides of the contact. At least two fluid systems are represented in the study area. Relatively wide-spread, pre-Laramide chlorite development occurred at temperatures and pressures higher than those present during Laramide deformation. A Laramide (or post-Laramie ) pervasive fluid system (especially near Ross Lakes Fault) is reflected by abundant fracture porosity, advanced feldspar alteration, and kaolinite development.
title: The Paleoecology and Geomorphology of Holocene Deposits of the Southern Malad River, Box Elder County, Utah
Creators: name: Elder, Ann Schaffer
Publisher: name: Utah State University
Year: 1992

description: Widespread Lake Bonneville sediments have been modified by river aggradation and degradation associated with Holocene fluctuations in the Great Salt Lake. Exposures of exceptionally abundant and well-preserved molluscan deposits in the Bear River Valley, Utah, allow detailed paleoenvironmental reconstruction of Holocene environments. The exposed basal unit consists of largely unfossiliferous deltaic silts and clays deposited during Lake Bonneville time ( roughly 11,000 - 13,000 yr B. P.). An unconformity representing at least 2000 yr separates the deltaic material from overlying highly fossiliferous stream sands. Eight species of molluscs, comprising a single community, occupied this low energy stream environment at 7690 ± 270 14C yr B. P. A second unconformity separates these sands from a dark brown silt unit deposited by a river-associated environment, most likely an over-bank marsh, at 2420 ± 135 14C yr B. P. Nine species of molluscs, comprising 3 communities, were present in this environment. Analysis of size-frequency distributions, percentage of pelecypod valves, preservation, and orientation of the shells that were present in each environment suggests that the 7690 ± 270 14c yr B. P. fossil assemblage has been only slightly altered by biostratinomic processes. The younger assemblage has also been altered, with the size-frequency curves of the smallest gastropods displaying normal distributions.
Geomorphic and stratigraphic data from the Malad River show that water levels in the Great Salt Lake twice rose and fell significantly during the Holocene epoch. The oldest rise, to an altitude of at least 1288 m, occurred before 7690 ± 270 yr B. P., perhaps in response to a worldwide period of climatic cooling. This high-stand was followed by a fall of lake level roughly corresponding to the classic Hypsithermal Interval, about 7000 - 5000 yr B. P. A second rise occurred by 2420 ± 135 yr B. P., when the Great Salt Lake rose to approximately 1286 m. During this second rise, the Malad River overflowed its levees and later, as the Great Salt Lake receded for a second time, the river was captured by a headward-cutting tributary of the Bear River.
The regional distribution of the fossiliferous deposits was controlled by the time at which capture occurred. Capture of the Malad channel by the Bear River occurred after the last fossiliferous sediments were deposited; thus no fossils are found downstream from the point of capture.

title: Late Quaternary Glacial Geology, Shoreline Morphology, and Tephrochronology of the lliamna/Naknek/Brooks Lake Area, Southwestern Alaska
Creators: name: Stilwell, Karen B.
Publisher: name: Utah State University
Year: 1995

description: This study focuses on the late-Wisconsin Brooks Lake glaciation, lake-level fluctuations, and volcanic deposits in the lliarnna/Naknek/Brooks Lake area on the northern Alaska Peninsula, southwestern Alaska. The Brooks Lake glaciation consists of five stades, from youngest to oldest: Kvichak, Uiarnna, Newhalen, Iliuk, and Ukak. This thesis reassigns the type Mak Hill moraine to a pre-late-Wisconsin glaciation, and considers the moraine enclosing Naknek Lake an early-late-Wisconsin deposit correlative to either the Kvichak stade, lliarnna stade, or both. The presence in the Iliamna Lake valley, and the absence in the Naknek Lake valley of a two-fold earliest-late-Wisconsin Kvichak/Iliamna glacial sequence suggest that the two glacial systems responded differently to climate change, or glacier/bed dynamics due to differing ice sources and glacier configurations. Plant macrofossils dated at 26,155 ± 285 I4C yr BP afford a new maximum-limiting age on the type Kvichak moraine. Slope angles on the type Kvichak and Iliamna moraines are less steep (~11-15°) than on younger Newhalen, lliuk, and Ukak moraines (~18-20° ), indicating that a considerable length of time separated the Iliamna and Newhalen stades. Correlation of this time-stratigraphic marker with other better dated Alaskan glacial sequences suggests that the interstadial occurred -13-14 ka. Following late-Wisconsin de glaciation of the Iliamna and Naknek lake basins, lake levels lowered, creating a flight of wave-cut terraces. Horizontal terraces, formed during latest-Wisconsin/early-Holocene time, at ~40 m above Iliamna Lake, and ~15 and ~30 m above Naknek Lake, suggest that these shorelines are not tilted as a result of glacial isostatic rebound or regional tectonism. The most prominent terraces above both lakes lay about halfway between the highest terrace and present-day lake level. If these terraces are correlative, then this indicates some climate control on lake-level fluctuations. Electron-microprobe analysis of six late-Pleistocene tephra samples allows five samples to be correlated with latest-Pleistocene Lethe tephra, and extends the Lethe ash plume ~125 km westward, and ~150 km northwestward of its presumed source area. Analysis of four early-Holocene black tephras fails to support any correlations, suggesting that there are multiple black tephras in the area. Ash C, a tricolored ash, consists of more than one chemically distinct tephra, and there is little consistency between color zones of the ash at different sites.

description: Dust emission was detected on main-belt asteroid 596 Scheila in December 2010, and attributed to the collision of a few-tens-of-meters projectile on the surface of the asteroid. In such impact, the ejected material from the collided body is expected to mainly comes from its fresh, unweathered subsurface. Therefore, it is expected that the surface of 596 was partially or entirely refreshed during the 2010 impact. By combining spectra of 596 from the literature and our own observations, we show that the 2010 impact event resulted in a significant slope change in the near-infrared (0.8 to 2.5 μm) spectrum of the asteroid, from moderately red (T-type) before the impact to red (D-type) after the impact. This provides evidence that red carbonaceous asteroids become less red with time due to space weathering, in agreement with predictions derived from laboratory experiments on the primitive Tagish Lake meteorite, which is spectrally similar to 596. This discovery provides the very first telescopic confirmation of the expected weathering trend of asteroids spectrally analog to Tagish Lake and/or anhydrous chondritic porous interplanetary dust particles. Our results also suggest that the population of implanted objects from the outer solar system is much larger than previously estimated in the main-belt, but many of these objects are hidden below their space-weathered surface.

description: The quantum charge-coupled device (QCCD) is one of the notable architectures to achieve large-scale trapped-ion quantum computers. To realize QCCD architecture, ions must be transported quickly while minimizing motional excitation. High-voltage sources are necessary to achieve such high-quality ion transport through a high secular frequency. In this study, we report the development of a field programmable gate array (FPGA)-based digital-to-analog converter (DAC) system with an output voltage range of +/-50 V and demonstrate its effectiveness in ion transport operations. The device provides 16-channel analog output, maximum update rate of 16 mega updates per second (MUPS), slew rate of 20 V/us, and bandwidth of > 200 kHz. By optimizing the voltage sets with quadratic programming, we experimentally confirmed that this DAC system can achieve more than twice the secular frequency attainable when its output range is restricted to +/-10 V, which is consistent with the fact that scaling all electrode voltages by a factor of 5 will scale the secular frequency by the square root of 5. Since the output range of many commercially available DACs is commonly limited to +/-10 V, this increase is effective for ion shuttling operations, such as transport, split and merge. The developed DAC system has potential to increase the speed of ion transport thereby reducing processing times in QCCD-based quantum computers.

description: The elliptic flow (squeeze-out) of neutrons, protons and light complex particles in reactions of neutron-rich systems at relativistic energies is proposed as an observable sensitive to the strength of the symmetry term in the equation of state at supra-normal densities. Preliminary results from a study of the existing FOPI/LAND data for 197Au + 197Au collisions at 400 A MeV with the UrQMD model favor a moderately soft symmetry term with a density dependence of the potential term proportional to (rho/rho_0)^gamma with gamma = 0.6+-0.3.

title: Groundwater and Surface-Water Interactions along Lower Medano Creek, Great Sand Dunes National Monument, Colorado

description: The objectives of this investigation are as follows: 1) review the existing hydrogeologic data for the San Luis Valley, the Great Sand Dunes Monument, and Medano Creek; 2) review the surface-water data that have been collected on Medano Creek; 3) collect or review previously collected water-level data obtained in the area of lower Medano Creek and correlate them with the surface-water data; 4) conduct constant-head permeameter tests on sand samples collected near the ground surface along lower Medano Creek; 5) produce a conceptual model of lower Medano Creek; and 6) produce a numerical model of lower Medano Creek that will predict the effect that a lowering of the regional water table could have on the terminus of flow of Medano Creek.
The complex hydrogeologic conditions under lower Medano Creek have been approximated with three homogeneous and anisotropic layers. A complex system of confining layers is represented by a single low-hydraulic-conductivity layer in the middle.
Numerical-modeling results suggest that the location of the terminus of flow in Medano Creek will recede significantly in response to a lowering of the regional water table, possibly by as much as 21,000 feet (6,400 meters) if the regional water table is lowered 150 feet (46 meters). These results indicate the qualitative effect that a lowering of the regional water table would have on lower Medano Creek, but they cannot be considered to be precise quantitative predictions. The results should be regarded with caution due to the paucity of data available.

description: Stacking two-dimensional van der Waals (vdW) materials rotated with respect to each other show versatility for the study of exotic quantum phenomena. Especially, anisotropic layered materials have great potential for such twistronics applications, providing high tunability. Here, we report anisotropic superconducting order parameters in twisted Bi2Sr2CaCu2O8+x (Bi-2212) vdW junctions with an atomically clean vdW interface, achieved using the microcleave-and-stack technique. The vdW Josephson junctions with twist angles of 0° and 90° showed the maximum Josephson coupling, which was comparable to that of intrinsic Josephson (IJ) junctions in the bulk crystal. As the twist angle approaches 45°, Josephson coupling is suppressed, and eventually disappears at 45°. The observed twist angle dependence of the Josephson coupling can be explained quantitatively by theoretical calculation with the d-wave superconducting order parameter of Bi-2212 and finite tunneling incoherence of the junction. Our results revealed the anisotropic nature of Bi-2212 and provided a novel fabrication technique for vdW-based twistronics platforms compatible with air-sensitive vdW materials.

description: In quantum dynamics, the Loschmidt amplitude is analogous to the partition function in the canonical ensemble. Zeros in the partition function indicate a phase transition, while the presence of zeros in the Loschmidt amplitude indicates a dynamical quantum phase transition. Based on the classical-quantum correspondence, we demonstrate that the partition function of a classical Ising model is equivalent to the Loschmidt amplitude in non-Hermitian dynamics, thereby mapping an Ising model with variable system size to the non-Hermitian dynamics. It follows that the Yang-Lee zeros and the Yang-Lee edge singularity of the classical Ising model correspond to the critical times of the dynamic quantum phase transitions and the exceptional point of the non-Hermitian Hamiltonian, respectively. Our work reveals an inner connection between Yang-Lee zeros and non-Hermitian dynamics, offering a dynamic characterization of the former.

description: Thermal Bogoliubov transformation is an essential ingredient of the thermo field dynamics -- the real time formalism in quantum field and many-body theories at finite temperatures developed by H. Umezawa and coworkers. The approach to study properties of hot nuclei which is based on the extension of the well-known Quasiparticle-Phonon Model to finite temperatures employing the TFD formalism is presented. A distinctive feature of the QPM-TFD combination is a possibility to go beyond the standard approximations like the thermal Hartree-Fock or the thermal RPA ones.

title: Analysis of Perched Groundwater Bodies beneath the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory
Creators: name: Jones, Alan V.

description: The migration of radionuclides and volatile chemicals through a thick sequence of unsaturated basalts and sedimentary interbeds has been documented in the Subsurface Disposal Area (SDA) at the Radioactive Waste Management Complex (RWMC) of the Idaho National Engineering Laboratory (INEL). The three mechanisms by which this migration may have occurred are seasonal infiltration from the ground surface within the SDA; flood events in 1962, 1969, and 1982; and the lateral movement of water from the spreading areas located nearby. It is currently thought that the contaminants migrated through the unsaturated sediments and basalt flows during the three flood events.
Transducers were used to monitor water level changes in seven wells: Two completed in a perched zone associated with an interbed at 110 feet (34 meters), and five completed in a perched zone associated with an interbed at 240 feet (73 meters). The data suggest that one of the wells completed in the perched zone associated with the interbed at 110 feet receives recharge from seasonal infiltration at the ground surface. This recharge occurs primarily from February to May. Snowmelt is the major source of water for infiltration.
One water sample was taken from this well, one water sample was taken from snowmelt at the surface within the SDA, and one water sample was taken from the Big Lost River, which is the source of water diverted into the spreading areas. The three water samples were analyzed for major ions, minor ions, and trace constituents. The water sample from the well was more similar chemically to the water sample from the snowmelt than to the water sample from the Big Lost River. The chemical data support the conclusion that the snowmelt is the source of recharge to the perched zone associated with the interbed at 110 feet.
The transducer data from the five wells completed in the perched zone associated with the interbed at 240 feet indicate that one well is dry, and one well has standing water that showed virtually no change in water level. Two of the remaining wells showed seasonal recharge, probably from precipitation. These two wells, and the remaining well, showed rapid water-level rises, and declines, shortly after 157 acre-feet (194,000 m3 ) of water were diverted into the spreading areas. The perched water body associated with the interbed at 240 feet probably receives recharge from both precipitation and from water diverted into the spreading areas.

description: Group field theory is a background-independent approach to quantum gravity whose starting point is the definition of a quantum field theory on an auxiliary group manifold (not interpreted as spacetime, but rather as the finite-dimensional configuration space of a single "atom" of geometry). Group field theory models can be seen as an extension of matrix and tensor models by additional data, and are traditionally defined through a functional integral whose perturbative expansion generates a sum over discrete geometries. More recently, some efforts have been directed towards formulations of group field theory based on a Hilbert space and operators, in particular in applications to cosmology. This is an attempt to review some of these formulations and their main ideas, to disentangle these constructions as much as possible from applications and phenomenology, and to put them into a wider context of quantum gravity research.

description: In this study, we determined the effect of doping with the noble metal Ag on Ir$_2$Te$_4$ superconductors. Based on the resistivity, magnetization, and heat capacity, we explored the changes in the superconductivity and charge density wave for Cu$_{1-x}$Ag$_x$Ir$_2$Te$_4$ as a function of isoelectric substitution. We assessed a complete set of competing states from suppressed charge density wave in the low doping region to superconductor in the middle doping region and re-entrant charge density wave in the high doping region, thereby obtaining an electronic phase diagram, where the superconducting dome was near bipartite charge density wave regions with a maximum superconducting temperature Tc of about 2.93 K at an Ag doping level of 12%. The lower H$_{c1}$ and upper H$_{c2}$ critical magnetic fields were determined for some representative samples in the Cu$_{1-x}$Ag$_x$Ir$_2$Te$_4$ series based on magnetization and resistivity measurements, respectively. We showed that H$_{c1}$ decreased whereas H$_{c2}$ increased as the doping content increased. The specific heat anomalies at the superconducting transitions $ΔC_{el}/γT_c$ for representative samples comprising Cu$_{0.92}$Ag$_{0.08}$Ir$_2$Te$_4$, Cu$_{0.88}$Ag$_{0.12}$Ir$_2$Te$_4$, and Cu$_{0.85}$Ag$_{0.15}$Ir$_2$Te$_4$ were approximately 1.40, 1.44, and 1.42, respectively, which are all near the Bardeen-Cooper-Schrieffer value of 1.43 and they indicate bulk superconductivity in these compounds.

title: The Quaternary Geology of the Eastern Side of the Greys River Valley and the Neotectonics of the Greys River fault in Western Wyoming
Creators: name: Allen Jones, L. C.
Publisher: name: Utah State University

description: The Greys River fault is the easternmost active normal fault associated with Basin and Range extension in the lntermountain seismic belt. It is a north south trending normal fault, located in the Sevier-age fold and thrust belt of western Wyoming , and bounds the west side of the Wyoming Range . The fault is at least 54 km long , and juxtaposes Permo-Pennsylvanian Wells Formation against various Triassic formations . Throw ranges from 100-1000 m. Seismic reflection data suggest that the Greys River fault is a listric normal fault that soles into the Darby thrust at depth. The fault offsets late Quaternary deposits on the west flank of the Wyoming Range. These deposits were mapped and differentiated on the basis of provenance and weathering characteristics. Four sets of moraines were identified in the study area. The moraines segregated into a local four-fold relative age sequence based on topographic position and relative dating parameters. The four-fold relative age sequence was correlated to Blackwelder's original Rocky Mountain glacial chronology. The most extensive glacial deposits were correlated to the late Pinedale glacial advance. Alluvial deposits associated with the Pinedale glacial cycle also contain evidence for late Quaternary faulting on the Greys River fault.
Maximum vertical surface displacements of late Quaternary deposits range from 8.6 m in Blind Bull Creek to 8.3 m in Box Canyon, 25 kilometers to the south. Between these points, vertical surface offset ranges from 3 to 8.2 meters. Three trenches were excavated in a late Pinedale alluvial terrace complex in Sheep Creek across a 7.5-meter scarp, a 3.1-meter scarp, and a 7.5-meter scarp-graben. The trenches revealed evidence for two paleoseismic displacements, the ages of which were constrained by eight radiocarbon dates. The most recent event involved a maximum displacement of 4.5 meters and occurred between 2110 +/- 60 and 2910 +/- 60 14C years BP. The earlier event was associated with a maximum observed displacement of 3.2 meters and occurred between 5080 +/- 60 and 5310 +/- 60 14C years BP. The moment magnitudes for these events, calculated from displacement and surface rupture length , range from Mw = 6.9 to 7.4 for both events. Scarp heights indicate an uplift rate of 1.11 mm / year. If the late Pinedale alluvium is 14,000 years old, then it appears no events occurred between 14,000 yr BP and 5310 14C yr BP, and two events have occurred between 5310 14C yr BP and 2110 14C yr BP. Such irregular recurrence interval is typical for normal faults in the Basin and Range and makes long-term prediction difficult.
