title: (e,2e) Spectroscopic Investigations of the Spectral Momentum Densities of Thin Carbon Films
Creators: name: Dennison, John Robert
Publisher: name: Utah State University
Year: 1985

description: An (e,2e) electron scattering spectrometer has been constructed and used for the first time to investigate the spectral momentum density of the valence bands of a solid target. This technique provides fundamental information about the electronic structure of both crystalline and amorphous solids. The three fundamental quantities, the band structure, electron density of states, and electron momentum distribution can be simultaneously derived from the measured (e,2e) cross section.
A review of single electron and (e,2e) scattering theory is given with an emphasis on scattering from solids. The effects of multiple scattering are discussed and a method of deconvoluting those effects from the measured (e,2e) cross section is developed.
There is a detailed description of the spectrometer design and operation with particular attention given to the electron optics and voltage distribution. The algorithms and software for computer aided data acquisition and analysis are also outlined, as is error analysis.
The techniques employed in the preparation and characterization of extremely thin film samples of a-C and single crystal graphite are described
An analysis of the data taken for a-C samples is complementary experiments and theory for graphite, diamond, and a-C which are given in a review of the literature. The existence of a definite dispersion relation ε(q) in amorphous carbon is demonstrated. The a-C band structure appears to be more similar to that of graphite than to that of diamond, however it differs significantly from both in some respects. The measured spectral momentum density seems compatible with a model of a-C based on small, randomly-oriented islands of quasi-2D graphite-like continuous random network structures. However, no definitive interpretations can be made until higher resolution experiments are performed on both a-C and single crystal graphite.

Creators: name: Hansen, Ken Cregg
Publisher: name: Utah State University
Year: 1978

description: The purpose of this study is to examine the settlement and institutions of Elsinore, Utah. The community was founded by Scandinavian converts to the Mormon church in the late Nineteenth Century. Their experience in adapting to the arid region of south central Utah is a chapter in the general movement by the Mormons to settle the Mountain West. The historical method was utilized to uncover extant documents on the subject. Interviews were held with the oldest citizens of the community and those who had a vast knowledge of the town. A period of three months was spent living in Elsinore and associating with the citizens. Present problems facing the town were examined along with the historic problems of the community. The study of Elsinore shows how an alien people adapted to the arid south central region of Utah by adhering to the guidance of the Mormon church. These Scandinavians accepted and rejected some of the Mormon institutions after experience with them. The assimilation of these people was delayed by the people themselves with the creation of institutions protecting their culture. Eventually, the people of Elsinore were assimilated into the broad American mass by attrition and loss of cultural symbols.

description: Gamma rays from extragalactic sources are attenuated by pair-production interactions with diffuse photons of the extragalactic background light (EBL). Gamma-ray bursts (GRBs) are a source of high-redshift photons above 10 GeV, and could be therefore useful as a probe of the evolving UV background radiation. In this paper, we develop a simple phenomenological model for the number and redshift distribution of gamma-ray bursts that can be seen at GeV energies with the Fermi satellite and MAGIC atmospheric Cherenkov telescope. We estimate the observed number of gamma rays per year, and show how this result is modified by considering interactions with different realizations of the evolving EBL. We also discuss the bright Fermi GRB 080916C in the context of this model. We find that the LAT on Fermi can be expected to see a small number of photons above 10 GeV each year from distant GRBs. Annual results for ground-based instruments like MAGIC are highly variable due to the low duty cycle and sky coverage of the telescope. However, successfully viewing a bright or intermediate GRB from the ground could provide hundreds of photons from high redshift, which would almost certainly be extremely useful in constraining both GRB physics and the high-redshift EBL.

description: The ePLANET project is a Coordination and Support Action cofounded by the European Commission through the Horizon 2020 program. ePLANET aims to deploy a new clustering governance for an energy transition based on a digital framework to share harmonized information, facilitating the adoption of coordinated energy transition actions by the European public sector. The improvements in the multi-level governance and the developed energy data visualization will be designed and implemented together with three regions: Girona region in Spain (DDGI), Zlín region in the Czech Republic (EAZK) and Crete Island in Greece (RDFC).
 Within this document (deliverable 5.7 “Follower Regions Evaluation Questionnaire”) the process, the methodology, and the results of the need survey are explained and the links to other activities within the project are highlighted. The results of the need survey will serve as the basis for the implementation of the joint exchange activities and the support activities for the follower regions.
 The report is structured in three sections. The first section introduces the report and sets the frame for the activities. The second section describes the methodology and results of the need survey and the third one shows the matchmaking approach between pilot and follower regions. The conclusions of the need survey for follower regions result in the final matching and the proposed joint activities displayed in Table 1.

description: This report is a local supplement to a wider-focused report on multiple uses of irrigation canals (Kennedy and Unhanand, 1974), primarily concerned with recreational uses. Increasing magnitude and variety of use generated several use conflicts, and the need for a closer look at canal-oriented activities arose. The intent of the study is to show local residents and planning officials the present physical condition of local canals and canal corridors, their present multiple uses, the importance of Cache Valley irrigation canals as recreation systems, and some possible future canal use alternatives.

description: Motivated by issues arising in computer science, we investigate the loop-free paths from the identity transformation and corresponding straight words in the Cayley graph of a finite transformation semigroup with a fixed generator set. Of special interest are words that permute a given subset of the state set. Certain such words, called minimal permutators, are shown to comprise a code, and the straight ones comprise a finite code. Thus, words that permute a given subset are uniquely factorizable as products of the subset's minimal permutators, and these can be further reduced to straight minimal permutators. This leads to insight into structure of local pools of reversibility in transformation semigroups in terms of the set of words permuting a given subset. These findings can be exploited in practical calculations for hierarchical decompositions of finite automata. As an example we consider groups arising in biological systems.

title: Detailed Analysis of the Domains of Mtr4 and How They Regulate Helicase Activity
Creators: name: Taylor, Lacy Leigh
Publisher: name: Utah State University
Year: 2014

description: There are numerous RNAs transcribed in the cell that are not directly involved in protein translation. Maintaining proper levels of RNA is crucial for cell viability, making RNA surveillance an essential process (equivalent to regulating protein levels). Mtr4 is an essential RNA helicase that activates exosome-mediated 3'-5' turnover in RNA processing mechanisms. Mtr4 has several binding partners, with the most prominent one being the complex Trf4/5-Air1/2-Mtr4 polyadenylating (TRAMP) complex. The polyadenylation and unwinding activity of TRAMP is modulated by a sensing mechanism in Mtr4 that detects both length and identity of 3'-end poly(A) tails. While it has been known that Mtr4 has an unwinding preference for substrates with a 3' poly(A) tail and a length of approximately 5 nucleotides, the mechanistic detail is unclear. It is also unclear what structural features of Mtr4 contribute to this sensing function. By using x-ray crystal structures of Mtr4, a ratchet helix was identified to interact with RNA substrates. Significant conservation of this ratchet helix along the RNA binding path was observed, similar to conservation patterns throughout Ski2-like and DEAH/RHA-box helicases. Structural characterization revealed a novel arch domain shown to bind structured RNAs, which may aid in cooperative RNA recognition in conjunction with the ratchet helix. In this thesis we demonstrate that the conserved residues at the third (R1030) and fourth (E1033) turns of the Mtr4 ratchet helix uniquely influence RNA unwinding rates. Furthermore, when mutated, ratchet helix positions confer slow growth phenotypes to Saccharomyces cerevisiae and are synthetically lethal in an Mtr4-archless background. The unwinding activity of these mutants when in the TRAMP complex alters the unwinding rates of Mtr4, and in some instances recovers substrate specificity. Our findings demonstrate the importance of R1030 and E1033 for helicase activity, and additionally link the arch domain of Mtr4 in essential unwinding events.

description: In this paper, the effect of electromagnetic field has been investigated on the spherically symmetric collapse with the perfect fluid in the presence of positive cosmological constant. Junction conditions between the static exterior and non-static interior spherically symmetric spacetimes are discussed. We study the apparent horizons and their physical significance. It is found that electromagnetic field reduces the bound of cosmological constant by reducing the pressure and hence collapsing process is faster as compared to the perfect fluid case. This work gives the generalization of the perfect fluid case to the charged perfect fluid. Results for the perfect fluid case are recovered.

description: We propose a new system where electron and hole states are electrostatically confined into a quantum ring in bilayer graphene. These structures can be created by tuning the gap of the graphene bilayer using nanostructured gates or by position-dependent doping. The energy levels have a magnetic field ($B_{0}$) dependence that is strikingly distinct from that of usual semiconductor quantum rings. In particular, the eigenvalues are not invariant under a $B_0 \to -B_0$ transformation and, for a fixed total angular momentum index $m$, their field dependence is not parabolic, but displays two minima separated by a saddle point. The spectra also display several anti-crossings, which arise due to the overlap of gate-confined and magnetically-confined states.

title: Effect of Predator Removal on Greater Sage-Grouse (Centrocercus urophasianus) Ecology in the Bighorn Basin Conservation Area of Wyoming
Creators: name: Orning, Elizabeth Kari
Publisher: name: Utah State University
Year: 2013

description: The decline of greater sage-grouse (Centrocercus urophasianus) populations across western North America has intensified conservation, research, and management efforts. Predator-prey interactions have been the focus of widespread scientific study, but little research has been conducted on the effects of predation and predator removal on sage-grouse ecology. This study had three main objectives: 1) identify the types of predators impacting hen survival and nest success, 2) compare the effect of predator removal on vital rates, and 3) evaluate habitat selection and movement. Over two years (2011-2012), an observational study and field experiment were used to test the effects of predation and predator removal on sage-grouse survival, nest success, and spatial ecology in Bighorn Basin, Wyoming. In year one, I quantified the impacts of predators on sage-grouse demographics and developed a basis for monitoring sage-grouse and predator populations. In year two, predator removal was modified to remove the primary nest and hen predator in this system: coyote (Canis latrans). I evaluated the impact of anthropogenic features and management on sage-grouse home range size, seasonal movement, and habitat selection for potential behavioral responses. Resource selection functions (RSFs) were used to determine habitat selection and identify differences at multiple spatial extents (seasonal and annual scales). Hen survival was improved in sites treated with coyote removal over the nesting period (P = 0.05) but no improvement was seen in annual hen survival (P = 0.19). Observed nest success was higher at the site without coyote removal (P < 0.0001). RSF modeling showed sage-grouse to be sensitive to predator removal, avoiding areas close to roads, with high well density, and steep slopes. While this study suggests predator removal does not benefit observed nest success, provides only short-term enhancement to survival, and may disrupt habitat selection, potentially benefits to other life stages could exist and be detected with more time and monitoring. By taking an experimental approach to examining the effects of predation and predator removal, this study advances our knowledge of sage-grouse ecology by identifying changes in demographic vital rates and habitat selection, propagating the best management possible for sage-grouse populations.
title: Pop2: A Potential Regulator of Hmt1-Catalyzed Arginine Methylation in Yeast
Creators: name: Excell, Celeste
Publisher: name: Utah State University
Year: 2014

description: Protein arginine methylation is an important post-translational modification that is vital in regulating various cellular processes such as gene transcription, cell signaling, and RNA processing. Protein arginine methyltransferases (PRMTs) are responsible for performing this important modification. PRMT1 (protein arginine methyltransferase 1) and Hmt1 (hnRNP methyltransferase 1) are the predominant PRMTs in humans and yeast, respectively. Despite growing momentum in this field, relatively little is understood about PRMT regulation. Further work discovering how PRMTs are regulated will greatly advance our understanding of diseases where PRMTs have been implicated, such as heart disease, viral pathogenesis, and cancer.
It has been discovered that a human protein called hCaf1 (human Ccr4-associated factor 1) is a regulator of PRMT1 with respect to certain substrates, and also colocalizes with PRMT1. We present data that suggest the yeast homolog of hCaf1, Pop2, may also perform a similar function on Hmt1. We provide data on the expression and purification of a truncation of Pop2 from S. cerevisiae, including the temperature sensitivity of one construct of Pop2 and its susceptibility to precipitation. We also demonstrated concentration-dependent inhibition of Hmt1-catalyzed methylation of histone H4 by Pop2 in vitro. Yeast cell lysates also showed altered patterns of methylation in the presence and absence of Pop2 in vivo. In an effort to understand the mechanism employed by Pop2 to accomplish this regulatory function, pull-downs were performed suggesting that Pop2 directly interacts with histone H4, a substrate of Hmt1. Mutagenic studies with Pop2 suggested a region that may be responsible for this interaction. Given these data, we hypothesized that Pop2 is able to inhibit the methylation of histone H4 via a substrate-sequestering mechanism. Further experimentation will determine the precise interaction surfaces of Pop2 and substrate, and continue to define the details of methylation inhibition by Pop2, including the scope of its influence in the cell.

description: Purpose: This study aims to examine the predictive relation between measures obtained from African American students’ written narrative language samples and reading achievement, as measured by standardized academic assessments.Method: Written language samples were elicited from 207 African American students in Grades 1–8. The samples were examined for morphosyntactic variations from standardized written Generalized American English (GAE). These variations were categorized as either (a) specific to African American English (AAE) or (b) neutral across AAE and standardized written GAE (i.e., considered ungrammatical both in AAE and in standardized written GAE). Structural equation modeling was employed to then examine the predictive relation between the density of AAE-specific forms in students’ writing and their performance on standardized assessments of literacy and reading vocabulary. This relation was examined while accounting for the density of dialect-neutral morphosyntactic forms, reported family income, age, and written sample length.Results: The written samples were highly variable in terms of morphosyntax. Younger students and those from lower income homes tended to use AAE-specific forms at higher rates. However, the density of AAE-specific forms did not significantly predict standardized literacy scores or reading vocabulary after accounting for dialect-neutral variations, income, and sample length.Conclusions: These results support the ongoing need to better understand the language, literacy, and overall academic development of students from all backgrounds. It may be essential to focus on dialect-neutral language forms (i.e., morphosyntactic forms that are consistent across both AAE and standardized written GAE) in written samples to maximize assessment validity across students who speak varying dialects of English.

description: We introduce a new equation describing epitaxial growth processes. This equation is derived from a simple variational geometric principle and it has a straightforward interpretation in terms of continuum and microscopic physics. It is also able to reproduce the critical behavior already observed, mound formation and mass conservation, but however does not fit a divergence form as the most commonly spread models of conserved surface growth. This formulation allows us to connect the results of the dynamic renormalization group analysis with intuitive geometric principles, whose generic character may well allow them to describe surface growth and other phenomena in different areas of physics.

title: Fault and Fluid Interactions in the Elsinore Fault-West Salton Detachment Fault Damage Zones, Agua Caliente County Park, California
Creators: name: Wood, Rebekah Erin
Publisher: name: Utah State University
Year: 2014

description: This study area provides a unique opportunity to study the intersection of the Elsinore and West Salton detachment faults in southern California, effusing warm springs, and alteration products in the midst of the fault intersection. Structural mapping and compiling previous maps supply an interpretation of the fault zone geometries within the Tierra Blanca Mountains. Geochemical analysis of the crystalline basement and altered protolith help determine the effects of faulting and fluid flow in the study area. In the Tierra Blanca Mountains, the Elsinore strike-slip fault system transitions from the double-stranded Julian segment and Earthquake Valley fault in the northwest, to the single-stranded Coyote Mountain segment in the southeast. A network of cross faults striking northeast connects the fault segments. The Coyote Mountain segment encounters the inactive West Salton detachment fault in the study area. The detachment fault is a barrier to fluid flow and exhibits primarily brittle deformation, while the Coyote Mountain segment is a conduit for fluid flow along the northeastern flank of the Tierra Blanca Mountains. The damage zone of the Coyote Mountain segment reaches widths up to 500 m and contains intense fracturing and subsidiary faults striking parallel to the main trace. The tonalite protolith is bleached, stained, and altered from water-rock interactions. The most intense bleaching is at a county park, where the protolith is altered to clays and zeolites while the mineralogy of the stained regions contains iron oxides and clinochlore in addition to quartz, Ca-rich albite, and biotite preserved from the protolith. The water chemistry at Agua Caliente hot springs shows the fluid is partially equilibrated. Groundwater temperatures likely reached 75-85°C at depths up to 2.14 km before rising to the surface. Frequent seismicity in the study region is related to the spring characteristics including water level, conductivity, and temperatures. Spring temperature and conductivity displayed three behaviors during the summer 2011 logging period, attributed to seasonal changes and most likely local seismicity as well. Conductivity seems to be the property most influenced by earthquake activity in the area. Changes in fluid chemistry between sampling periods may indicate mixture with other fluid sources.

Aged health care

description: Sources are an essential component to journalistic reporting and are a critical determinant of its quality. Who or what is referenced, in which ways, how often, and why matters and can reveal important insights into journalistic practice as well as the values and implicit assumptions of both the news outlets and broader societies under study. Acknowledging this, this study examines sourcing practices of journalists working at four national news outlets in Australia over a 15-month period as they report on the topic of ageing and aged care. Specifically, the study investigates six key questions related to sourcing: Who or what is used as a source? What is the proportion of elite to non-elite sources? What is the identifiability of sources? What is the number of sources per news story? What is the proportion of primary to secondary sources per story? And how are these aspects different for different news outlets? The results reveal that journalists overwhelmingly used elite rather than non-elite sources in their reporting on this topic, used politicians most frequently in their coverage, and used an average of five sources per article. However, who was used as a source varied markedly by outlet.

description: In this paper we compute the leading order of the Casimir energy for a free massless scalar field confined in a sphere in three spatial dimensions, with the Dirichlet boundary condition. When one tabulates all of the reported values of the Casimir energies for two closed geometries, cubical and spherical, in different space-time dimensions and with different boundary conditions, one observes a complicated pattern of signs. This pattern shows that the Casimir energy depends crucially on the details of the geometry, the number of the spatial dimensions, and the boundary conditions. The dependence of the \emph{sign} of the Casimir energy on the details of the geometry, for a fixed spatial dimensions and boundary conditions has been a surprise to us and this is our main motivation for doing the calculations presented in this paper. Moreover, all of the calculations for spherical geometries include the use of numerical methods combined with intricate analytic continuations to handle many different sorts of divergences which naturally appear in this category of problems. The presence of divergences is always a source of concern about the accuracy of the numerical results. Our approach also includes numerical methods, and is based on Boyer's method for calculating the electromagnetic Casimir energy in a perfectly conducting sphere. This method, however, requires the least amount of analytic continuations. The value that we obtain confirms the previously established result.

title: Historical Biogeography of North American Nightsnakes and Their Relationships Among the Dipsadines: Evidence For Vicariance Associated With Miocene Formations of Northwestern Mexico
Creators: name: Mulcahy, Daniel G.
Publisher: name: Utah State University
Year: 2006

description: I used a Hierarchical approach to study historical biogeography in a group of colubrid snakes found in western North America. I combined small regions of mtDNA sequence data from a large number of individuals, with complete mt-genomic data. First, I investigated the relationships among leptodeirines-a presumed subgroup of dipsadines includeng nightsnakes (Pseudoleptodeira, Eridiphas, and Hypsiglena) - using ~1.5 Kb of data (cob and nad4). The relationships differed among parsimony, likelihood, and bayesian analyses. All analyses supported the monophyly of the nightsnakes; however, none supported the monophyly of the leptodeirines. Instead, these data supported a new hypothesis that the dipsadines were ancestrally rear-fanged and preyed on small vertabrates (frogs and lizards), such as the nightsnakes, while the more derived lineages have modified anterior maxillary dentition and prey strictly on invertabrates.
Secondly, using an evolutionary species concept, I test species-subspecies boundaries in the wide-ranging hypsiglena, which has over 17 forms described, by collecting ~800 bp of sequence data (nad4 and tRNA) from ~ 175 individuals. Six major clades, concordant with geography, were recognized as species: Chihuahuan Destert (H. jani); central-western Mexico (H. torquata); upland Jalisco (H. Affinis); central California-Cape of Baja ("Coast," H. ochrorhyncha); Sonoran, Mojave, and Great Basin deserts ("Desert" H. chlorophaea), and an undescribed form from the Sonoran-Chihuahuan desert transition zone ("cochise"). The relationships among the major clades were not well resolved.
Lastly, I collected complete mt-genome sequence data from 15 individuals including Eridiphas, Pseudoleptodeira, each of the major clades of Hypsiglena, and Sibon and Imantodes. All combined genomic-level analyses contained overwhelming support for a single phylogeny. These data, in conjunction with the phylogeographic data, supported my hypothesis that vicariance associated with the Miocene seperation of the Cape of Baja from mainland Mexico formed the Baja endemic Eridiphas, followed by subsequent range expansion and dispersal of Hypsiglena onto the northern portion of the peninsula and an even later vicariance event associated with the northern inundation of the gulf of California during the Pliocene. Hysiglena later dispersed down the Baja California Peninsula, coming into secondary contact with Eridiphas, forming a ring-like distribution around the Gulf of California.
title: Relationships of Vegetation to Environment in Canyonlands National Park
Creators: name: Loope, Walter Lee
Publisher: name: Utah State University
Year: 1977

description: The vegetation of Canyonlands National Park, Utah, has been described from 157 samples located throughout the Park. Species frequency, density and cover were recorded along with measurements of soil thickness, slope, aspect, elevation and geologic substrate at each site. Measurements of soil texture, pH, and electrical conductivity were taken for a representative subsample. A map of the vegetation of the Park was made by relating the sample points to their corresponding spectral signatures on vertical aerial photographs and locating boundaries between vegetation units by means of changes in photo signatures.
Vegetation in these arid to semi-arid environments appears to be strongly related to particular combinations of regolith thickness, bedrock composition and depth to water table. Elevation and slope exposure control vegetation patterns to a much smaller extent. Vegetational units are distinct, and can be readily visualized. The six units mapped, in order of relative importance, (area covered) were: blackbrush, juniper-pinyon woodlands, semi-desert grasslands, sagebrush-fourwing saltbush shrublands, salt-desert shrublands and riparian tall shrublands. These vegetational units are related to specific combinations of environmental factors. Boundaries between units are sharp vegetationally and environmentally. Moisture availability appears to be the key factor, but effective soil moisture is largely controlled by regolith/bedrock relationships.
Grasslands predominate at all elevations where regolith is over 50 cm in thickness and there is no access of plant roots to the water table. Regolith that is uniformly thinner than 50 cm supports vegetation dominated by blackbrush (Coleogyne ramosissima). Sandy areas that provide immediate root access to the water table support thickets of Salix, Tamarix, and other riparian shrubs. Shrublands dominated by Atrinlex canescens and Artemisia tridentata occur on thicker sand deposits with seasonal root access to capillary water. Where competent bedrock is exposed and joints are developed, Pinus edulis, Juniperus osteosperroa and various upland shrubs dominate. Several species of Atrinlex dominate the salt-desert shrublands where clayey shales crop out.
Historical grazing use by domestic livestock has altered the composition and cover in grasslands, chiefly in the southern part of the Park. Elsewhere, grassland modification is slight because of more difficult access. other vegetation types have experienced less obvious changes.
The many abandoned roads within the Park date chiefly from extensive mineral exploration in the early 1950's. Secondary succession on these disturbed areas is extremely slow.

description: We derive a precise link between series expansions of Gaussian random vectors in a Banach space and Parseval frames in their reproducing kernel Hilbert space. The results are applied to pathwise continuous Gaussian processes and a new optimal expansion for fractional Ornstein-Uhlenbeck processes is derived. In the end an extension of this result to Gaussian stationary processes with convex covariance function is established.

description: Jürgen Ehlers developed \emph{frame theory} to better understand the relationship between general relativity and Newtonian gravity. Frame theory contains a parameter $λ$, which can be thought of as $1/c^2$, where $c$ is the speed of light. By construction, frame theory is equivalent to general relativity for $λ>0$, and reduces to Newtonian gravity for $λ=0$. Moreover, by setting $\ep=\sqrtλ$, frame theory provides a framework to study the Newtonian limit $\ep \searrow 0$ (i.e. $c\to \infty$). A number of ideas relating to frame theory that were introduced by Jürgen have subsequently found important applications to the rigorous study of both the Newtonian limit and post-Newtonian expansions. In this article, we review frame theory and discuss, in a non-technical fashion, some of the rigorous results on the Newtonian limit and post-Newtonian expansions that have followed from Jürgen's work.

title: Tertiary Igneous Rocks of Northeastern Cache Valley, Idaho
Creators: name: Willard, Parry D.
Publisher: name: Utah State University
Year: 1972

description: The tuffs and limestones of the Tertiary Salt Lake Formation in northeastern Cache Valley, Franklin County, Idaho, are intruded by basic and intermediate igneous dikes and sills. The Tertiary intrusives are exposed in an area 10 miles long and 2 miles wide between Bear River and Maple Creek in the foothills of the Bear River Range east of Preston, Idaho. They trend north-northwest. The intrusives are mostly diabase but include a small body of syenodiorite and several small andesite dikes. The intrusives seem to be emplaced along early Basin and Range faults. They are limited to the Cache Valley Member of the Salt Lake Formation and pre-date the Mink Creek Member of the Salt Lake Formation in the mapped area. The probable age of the intrusive activity is late Pliocene. Because the igneous rocks are well exposed on both sides of the Cub River valley, they will be referred to as the Cub River Diabase. The Cub River Diabase could represent a southward extension of the early igneous activity in the Snake River Plain.
Precise limits from lepton flavour violating processes on the Littlest Higgs model with T-parity

description: We recalculate the leading one-loop contributions to mu > e gamma and mu -> eee in the Littlest Higgs model with T-parity, recovering previous results for the former. When all the Goldstone interactions are taken into account, the latter is also ultraviolet finite. The present experimental limits on these processes require a somewhat heavy effective scale ~2.5 TeV, or the flavour alignment of the Yukawa couplings of light and heavy leptons at the ~10% level, or the splitting of heavy lepton masses to a similar precision. Present limits on tau decays set no bounds on the corresponding parameters involving the tau lepton

description: The strong coupling constants between light vector mesons and octet-decuplet baryons are calculated in framework of the light cone QCD sum rules, taking into account SU(3) flavor symmetry breaking effects. It is shown that all strong coupling constants can be represented in terms of a single universal function. Size of the SU(3) symmetry breaking effects are estimated.

title: Structural Geology of Eastern Part of the Smithfield Quadrangle, Utah
Creators: name: Galloway, Cheryl Leora
Publisher: name: Utah State University
Year: 1970

description: The mapped area represents the eastern three-fourths of the Smithfield quadrangle, Utah. This quadrangle is located in the central part of northern Utah about 8.6 miles south of the Utah- Idaho State Line. The Bear River Range, along the eastern margin of the quadrangle, consists of stratigraphic units ranging in age from Precambrian to Devonian. The Salt Lake Formation of Tertiary age rests unconformably on Precambrian quartzite and Paleozoic units along the western side of the range. The Lake Bonneville Group overlaps Cambrian rocks in the southern part of the area and overlaps the Salt Lake Formation in the northern part.
The Paleozoic rocks of the mapped area dip generally east on the western limb of the Logan Peak syncline. The east-dipping beds of the western limb, along the mountain front, are broken by east-dipping bedding-plane faults and by west-dipping high-angle and low-angle thrust faults. A prominent west-dipping surface probably formed as a thrust fault; however, later westward sliding took place on this surface. The bedding-plane faults are interpreted to have formed by: eastward sliding of the mountain mass. Progressive local deformation, on the western limb of the Logan Peak syncline, produced high-angle and low-angle thrust faults successively. The folding and thrust faulting are related to the Laramide orogeny and occurred during the Cretaceous Period and the early part of the Tertiary Period.
Numerous gravity faults extend along the western front of the Bear River Range. The relative collapse of Cache Valley, early in the Tertiary Period, produced great topographic relief. This resulted in slope instability and, as a consequence, large masses moved down the west-dipping surface and two major landslides occurred. The landslides seem to have moved over the lower member of the Salt Lake Formation and seem to have been covered by conglomerate of the upper member. Gravity faulting has continued to the present time.
