title: Population and Community Dynamics of Freshwater Decapods in Response to Ecological and Anthropogenic Factors in Subtropical Streams in the Caribbean
Creators: name: Perez-Reyes, Omar
Publisher: name: Utah State University
Year: 2015

description: Streams have been impacted by human activities in a variety of ways. Over time, these ecosystems become dominated by the most resilient species, with significant losses in the natural components that provide valuable ecosystem services to people. In impacted streams, the loss of ecosystem services often is not recognized until the stream has already been dramatically altered. In this study, I provide data on the natural distribution of freshwater decapods and the status of decapod communities in streams with different land use histories.
I reviewed the decapod distribution for the Caribbean to provide an update of the species that inhabit the freshwater systems. I determined the presence of 18 species of decapods in Puerto Rico and concluded that these decapods follow the island-species relationship in the Caribbean. Also, I present data associated with decapod community dynamics in watersheds with different urban development. As, expected the highly urban watershed had lower diversity and density of decapods than the medium and low urban watersheds. The variations in decapod communities among watersheds correlated with the degradation of the physical-chemical environments and clearing of the riparian zones. I compare the food webs among streams with different human impacts. Specific influences of point/nonpoint sources of N could be distinguished in food web components. This shows to an effect of human activities on the stream and watershed. In addition, I determined the effect of abiotic and biotic factors on the growth of A.lanipes (0.27 mm) and X.elongata (0.1 mm) over the 10-year period of study. The results showed that these species transform a wide range of organic materials into their biomass. Finally, I developed a series of education projects which promote the understanding and knowledge of freshwater ecosystems; interactions and the organisms that inhabit these systems. The results showed an increasing interest about freshwater fauna and ecosystems.
I concluded that: a) the distribution of freshwater decapods in the Caribbean islands follows the area-species relationship; b) urbanization represents one of the many distinct land uses that affect habitat structure, energy sources and biotic interactions; and c) it’s necessary to present the results of our research to the general public in ways that are easily understood.
Theory and design of a wave generator for a short flume
Creators: name: Chappell, Eric Reginald
Publisher: name: University of British Columbia
Year: 2011

description: This thesis describes the design of a proposed, new hydraulic laboratory, wave generator for use in a 39'-4¼'' long, 30" wide and 36" deep flume, and the re-design of a small wave generator previously built for a 21'-3 5/8" long, 8 3/4" wide and 10 5/8" deep flume. These relatively short flumes are installed in the Hydraulics Laboratory of the Department of Civil Engineering, University of British Columbia, and the installation of the proposed, new wave generator would augment the present limited wave research facilities. The project is supported by an operating grant from the National Research Council of Canada. The preparatory study of laboratory wave generators in use, presented herein, was made to determine how they function and their design problems. It was concluded that a rigid paddle, double articulation type would be best for generating deep-water, transition and shallow-water waves in a flume of relatively short length. Biesel's wave generator theory is outlined and was used in estimating wave heights and in determining power and strength requirements. The existing wave generator for the "small" flume is a rigid paddle, double articulation type. It did not function satisfactorily due to a very irregular paddle motion. The causes were isolated and a new drive system designed and installed, with good results. The resulting new operating specifications are: power = 1. Hp (D.C.) wave period range = 0.34 to 2.1 sees. design water depth = 6.5" estimated maximum wave height = 4" The proposed, new wave generator for the "large" flume is a rigid paddle, double articulation type designed around the adjustable paddle concept of G.D. Ransford (1949) as modified by Lt. CB. Coyer (1953). The designed operating characteristics are: power = 10-Hp (D.C.) wave period range = 0.68 to 4.28 secs. design water depth = 25" estimated maximum wave height = 14"

description: Charge excitations in Mott insulators (MIs) are distinct from their band-insulator counterparts and they can provide a mechanism for energy harvesting in solar cells based on strongly correlated electronic materials. In this paper, we study the real-time dynamics of holon-doublon pairs in a MI connected to metallic leads using the time-dependent density matrix renormalization group method. The transfer of charge across the MI-metal interface is controlled by both the electron-electron interaction strength within the MI and the voltage difference between the leads. We find an overall enhancement of the charge transfer as compared to the case of a (noninteracting) band insulator-metal interface with a similar band gap. Moreover, the propagation of holon-doublon excitations within the MI dynamically changes the spin-spin correlations, introducing time-dependent phase shifts in the spin structure factor.

description: A network of seven Huon pine ring-width chronologies is constructed from sites ranging in elevation from 200 to 950 metres above sea level in western Tasmania. The chronologies are analysed individually and collectively to explore Huon pine‘s response to climate as a function of elevation. Three chronologies from greater than 700 metres in elevation exhibit a strong, direct response to temperature for most growing season months (p<0.05), while three from below 700 metres exhibit a weaker, direct response to growing-season temperature, and a strong, inverse relationship with temperature of the prior season of growth, also significant at the 0.05 level. Moisture availability at these temperate rainforest sites is less growth-limiting than temperature, and significant correlations for January (inverse) and April (direct) of the year of growth largely reflect the inter-relationships between temperature, precipitation and cloudiness, and their combined influence on photosynthesis, particularly at higher-elevation sites. A rotated Principal Component Analysis reveals a clear grouping of the high and low-elevation chronologies, represented by the first and second eigenvectors, respectively. The 700 metre Lake Marilyn Low chronology is revealed to be a transitional site between the two groupings, and likely reflects an important climatic ecotone where both temperature and photosynthetically-active radiation drop below optimum levels for the species, and begin to directly inhibit growth. Tasmania's west coast climate has been shown to exhibit a distinct vertical structure, exemplified by a subsidence-inversion layer above 900 metres. Temperature increases slightly with altitude above 930 metres (the elevation at which a peak in daily minimum and maximum humidity levels is observed) before decreasing again. A dense, orographically-generated cloud-zone of reduced light and temperature has a mean altitude between 700 and 900 metres, with the steepest drop in both air and soil temperature exhibited between 850 and 930 metres. This structure can account for Huon pine‘s changing response to climate with elevation as described in this paper, and reinforces the importance of careful site selection for dendroclimatic research. In the case of reconstructing warm-season temperature from Tasmanian Huon pine, the desired signal might be maximised through sampling at the few rare, subalpine stands which have been located in western Tasmania. The great length afforded by the low-elevation Huon pine resource may ultimately yield a far more detailed reconstruction of regional climate throughout the Holocene, with respect to a vertical profile, following the development of more sound, mechanistically-based response models.

description: We calculate differential energy spectra ($x_F$-distributions) of charmed particles produced in proton-nucleus collisions, assuming the existence of intrinsic heavy quark components in the proton wave function. For the calculation, the recently proposed factorization scheme is used, based on the Color Glass Condensate theory and specially suited for predictions of a production of particles with large rapidities. It is argued that the intrinsic charm component can, if it exists, dominate in a sum of two components, intrinsic + extrinsic, of the inclusive spectrum of charmed particles produced in proton-nucleus collisions at high energies, in the region of medium $x_F$, $0.15 < x_F < 0.7$, and can give noticeable contribution to atmospheric fluxes of prompt muons and neutrinos.

title: Relations among Teachers' Implicit Theories of Intelligence, Standardized Achievement Testing, and Classroom Goals
Creators: name: Ringle, Sydnie W.
Publisher: name: Utah State University
Year: 2015

description: An achievement gap between ethnic minorities and White Americans continues to exist within the U.S., as well as between the U.S. and varying countries. Research has identified several factors that contribute to this gap, such as differences in curricula across countries, teacher quality, and school funding. In addition to these factors, teachers’ implicit theories of intelligence may also contribute to the achievement gap. Whether teachers view intelligence as fixed (entity theory) or malleable (incremental theory) can impact instructional practices, specifically the use of performance and learning goals. Performance goals focus on evaluation, ability, and performance rather than mastery of material, growth, and overall learning as seen in learning goals. Research is limited regarding the development of implicit theories of intelligence; however, there is evidence culture may be involved. Identifying specific cultural practices that influence the development of implicit theories of intelligence may provide a unique perspective on pedagogy and how teachers interact with students. One cultural practice that may be related to the development of implicit theories of intelligence is standardized achievement testing. The current study used survey methodology to evaluate the relation between implicit theories of intelligence, perceived pressure from standardized achievement testing, and classroom goal structures and the differences between these variables amongst full-time teachers (N = 45). Results indicated significant differences in perceived pressure from standardized achievement testing amongst teachers with classrooms containing lower percentages of reading and math proficient students as well as significant differences in classroom goal structures amongst teachers with classrooms containing fewer ethnic minority and ELL students. Implications of these findings and areas of future research are discussed.

description: Here, the test materials are released that were used in the second intervention study conducted over a period of 6 to 8 weeks in two high-schools in Berlin, Germany (2018, 2019). The aim of this study was to evaluate how students in Latin classes in Germany deal with their vocabulary knowledge and whether they consider the context of words. A key question of the still ongoing research project is: How can vocabulary competence in a historical language such as Latin be acquired and deepened by using corpus-based, i.e. context-based, methods? This question is based on a broad understanding of vocabulary that refers back to theories of the mental lexicon. Note: The English version is a translation. Because of the context-based questions pretest and posttest differ in the selected myth, but not in the given tasks.

description: This paper discusses the ancient wines considered among the grands crus of antiquity in Sicily, as widely mentioned by literary sources. The wealth of the late-Roman Villa on the Tellaro river, near Noto in South-East Sicily, with its extraordinary landscape still covered in vineyards and surviving polychrome mosaics in its pars urbana, is an emblematic model of the variety and fineness of ancient fortunes. The paper also alludes to the mosaics that highlight the aristocratic taste of the Villa’s dominus, used to entertain and impress his guests with some scenes from Homer's Iliad, coupled with an en plein air picnic (with the diner on the left holding a glass of red wine) and four overflowing craters with rich harvests goods, including grapes. The luxury of the rooms such as the ‘Room of Bacchus’, as recently re-baptized by Wilson (2016), seems to particularly deliver a unique message of opulence and appears to invite guests to celebrate the God of wine.

description: We explore the device potential of tunable-gap bilayer graphene FET exploiting the possibility of opening a bandgap in bilayer graphene by applying a vertical electric field via independent gate operation. We evaluate device behavior using atomistic simulations based on the self-consistent solution of the Poisson and Schroedinger equations within the NEGF formalism. We show that the concept works, but bandgap opening is not strong enough to suppress band-to-band tunneling in order to obtain a sufficiently large Ion/Ioff ratio for CMOS device operation.

Year: 2015

description: There are two studies in this dissertation. Both are about a program called “PICK a Partner.” The first study looked at how the program went for 682 people from the community who were taught PICK. These people ranged in age from 18 to 25. Those in attendance were given questions at the beginning of the program about their thoughts, perceptions, and knowledge regarding dating relationships. They were given these same questions at the end of the program. The scores on the questions at the end of the program were compared with scores on the questions at the beginning of the program. Peoples’ scores increased from before to after on all four questionnaires. These scores were also compared with scores from a group of students aged 18 to 25 from a university. Those that attended the program had higher scores; the scores of those from the university who did not attend the program stayed about the same. The second study examined how teachers influence scores and how individual characteristics of participants influence change in scores. The second study showed that teacher characteristics do matter somewhat in helping participants increase in knowledge. In addition, how religious a person is and whether they are a man or woman also matter, but only a little, in helping participants increase in knowledge. Future studies on PICK and the strengths and weaknesses of these studies are discussed.

description: The waste problem is not only the responsibility of the central government, but local governments play an important role in how efforts must be made to manage waste at the regional level. The purpose of this study is to see how the efforts made by the Kebumen district government, Indonesia in solving the waste problem in the region. this research method is carried out with a descriptive qualitative approach with data collection techniques using observation and in-depth interviews with agencies in Kebumen Regency that are responsible for waste management. The Environment and Forestry Service of Kebumen Regency is responsible for the existing waste problem. The findings of this research are several efforts that have been made starting from making regional regulations related to waste management in the Kebumen district and also collaborating with existing stakeholders, including the private sector, the community, and academics. In addition, it also builds public awareness regarding how waste becomes a serious problem if it is not managed properly. The obstacles faced are divided into two, namely internal obstacles and external obstacles. Internal constraints include 1) Lack of budget; 2) Lack of coordination between local government agencies; and 3) Lack of public awareness. As for external constraints, including; 1) Urbanization; and 2) industrial and service activities in urban areas.

Analysis of elastic shells of revolution with membrane and flexure stresses under arbitrary loading using trapezoidal finite elements
Creators: name: Agrawal, Krishna Murari
Publisher: name: University of British Columbia
Year: 2011

description: Analysis of a general shell of revolution with arbitrary loading and boundary conditions using the Finite Element approach, well-suited for use with the electronic computer, is presented. The shell is approximated by an assemblage of flat, equilateral trapezoids and isosceles triangles connected to each other at the corners. The assumptions involved in transforming a piece of plate into a finite element are defined. Uncoupled plane stress and flexure stiffness matrices for the above-mentioned shapes of the finite elements are derived from considerations of (i) statics, and (ii) virtual work (energy). Statics matrices are asymmetric with the exception of the triangle plane stress stiffness matrix. However, it is important to note that irrespective of the size of the trapezoid element, in conditions of uniform stress the nodal forces satisfy Betti's reciprocal theorem. When a trapezoid reduces to a rectangle, the asymmetry of plane stress and flexure stiffness matrices disappears. Asymmetry of the Statics matrix is removed by averaging the matrix and its transpose. This process corresponds to introducing self-equilibrating nodal forces which disappear in conditions of uniform stress. Suitable direction cosine matrices are derived to transform the displacements and forces from the element coordinate system to the shell coordinate system. The accuracy of the formulation is demonstrated in several examples by comparing the finite element solution with the elasticity solution. The comparison suggests convergence of the results to the correct solution on reduction of the element size.

Year: 1975

description: Forty-three and 54 Ferruginous hawk (Buteo regalis) pairs were found occupying territories in northern Utah and southeastern Idaho during 1972 and 1973, respectively. Of these 38 and 27 nesting pairs laid eggs. Nesting success was 77.1 percent in 1972 and 74.6 percent in 1973. for successful nests, an average of 2.9 and 2.6 young hatched and 2.7 and 2.3 young fledged during the respective years. This population is reproductively comparable to others in Utah and Colorado. Analysis of prey items collected from the nests indicated that black-tailed jack-rabbits (Lepus californicus) constitute 86 percent of the biomass (by weight) of three major prey species consumed by ferruginous hawks in this area. Jackrabbit density may be a major determinant of the number of young produced in a given year. Weight gained by the nestlings showed a marked sexual dimorphism. Female fledgelings weighed up to 1.43 times as much as males. Criteria were developed for sexing ferruginous hawks by measuring the diameter of the hallux. Mortality of 17 birds from the study area was recorded, of which 47 percent were immature birds. A total of 108 fledglings were banded and marked with color-coded patagial wing markers. Band reports of five (10 percent) of these birds were received. Utah juniper (Juniperus osteosperma) provided nest sites for 96.0 percent of the nests while three percent were built on the ground. Plant community types were determined at 63 nesting sites from aerial photographs. Dominant vegetation around nest sites were desert shrub types and crested wheatgrass (Agropyron cristatum) seedings. The possible impact of land management practices on ferruginous hawks is discussed.

Recently, the pump-probe approach has been applied to nano-engineered materials to optically generate and detect acoustic waves in the GHz-THz frequency range. In this paper, we review the latest advances on ultrafast generation and detection of thermal gradients and pseudo-surface acoustic waves in two-dimensional lattices of metallic nanostructures. Comparing the experimental findings to the numeric analysis of the full thermo-mechanical problem, these materials emerge as model systems to investigate both the mechanical and thermal energy transfer at the nanoscale. The sensitivity of the technique to the nanostructures mass and shape variations, coupled to the phononic crystal properties of the lattices opens the way to a variety of applications ranging from hypersonic waveguiding to mass sensors with femtosecond time-resolution.ens the way to a variety of applications ranging from hypersonic waveguiding to mass sensors with femtosecond time-resolution.

description: This paper presents a multicentury reconstruction of May precipitation (1200–1997) for the mid-Atlantic region of the United States. The reconstruction is based on the first principal component (PC1) of two millennial-length Juniperus virginiana L. (eastern red cedar) tree-ring chronologies collected from rocky, limestone sites in the Ridge and Valley province of West Virginia. A split-calibration linear regression model accounted for 27% of the adjusted variance in the instrumental record and was stable through time. The model was verified by the reduction of error (RE = 0.21) and coefficient of efficiency (CE = 0.20) statistics. Multidecadal changes in precipitation were common throughout the reconstruction, and wetter than median conditions and drier than median conditions occurred during the medieval climate anomaly (1200–1300) and the Little Ice Age (1550–1650), respectively. The full reconstruction contained evidence of interannual and decadal variability; however, the twentieth century recorded the greatest number of decadal extreme wet and dry periods. A comparison of the May precipitation reconstruction to other regional reconstructions [Potomac River, Maryland, streamflow (Cook and Jacoby); Virginia/North Carolina July Palmer hydrologic drought index (PHDI; Stahle et al.); Missouri July PHDI (Cleaveland and Stahle); and White River, Arkansas, streamflow (Cleaveland)] showed that the eastern U.S. decadal drought and pluvial events extended into the mid-Atlantic region. A positive correlation between PC1 and the winter North Atlantic Oscillation (NAO) index and comparisons of smoothed May precipitation and the NAO (Luterbacher et al.) indicated that J. virginiana’s response to May precipitation was mediated by winter temperature.

Publisher: name: Utah State University
Year: 1983

description: The purpose of this study was to develop a model to predict the college mathematics courses a freshman could expect to pass by considering their high school mathematics preparation. The high school information that was used consisted of the student's sex, the student's grade point average in mathematics, the highest level of high school mathematics courses taken, and the number of mathematics courses taken in high school.
The high school sample was drawn from graduated Seniors in the State of Utah for 1979. The college sample was drawn from the fall semester 1980 at Utah State University, Weber State College, University of Utah, Westminster College, and Brigham Young University. The model was developed using ACT Scores as the dependent variable with the high school data in one equation and the college data in another equation and then predicting from high school to college using the ACT Scores as the bridge.
The results showed that those students that had courses in the higher levels of mathematics in high school, were significantly more successful! in college mathematics. The level of mathematics was more significant than the grades received in mathematics.
Females who had had higher levels of mathematics in high school were as successful! as males on that level.

description: The first coinage took place in the second half of the VII c. B.C. in the kingdom of Lydia and in some of the most important coastal poleis of Asia Minor; a few decades afterwards it spread in the Aegean islands and in Continental Greece. It reached the colonies of Magna Graecia and Sicily in the fifties/forties of the VI c. B.C., Sybaris and Selinus being the first cities to adopt silver coins as a mean of internal commerce and international exchanges. In Sicily, as for most of the Greek cities, the city emitting the coins is identifiable from the images shown on the two faces of the coin itself, normally referring to local gods, myths, or products of the land. Given the importance of wine production in several Siceliote centres, Dionysos and his attributes − as well as subjects connected to his thiasos or to wine, such as satyrs and fauns, grapes and kantharoi or oinochoai − are often depicted on one or on both sides of the coins. This is for example the case for the city of Naxos in Sicily, now Giardini Naxos, where around 530 B.C. a beautiful Archaic head of the god of wine is associated with a grape on the reverse of the coin; or later in 460 B.C. the reverse will show a itiphallic silenus drinking from a cup. The paper also mentions the other Siceliote cities − such as Catana, Calacte, Galaria, Nacona and Tauromenio − whose coin types like those described above clearly witness a wine production in the Greek and Roman periods.

description: We classify complex projective varieties of dimension $2r \geq 8$ swept out by a family of codimension two grassmannians of lines $\mathbb{G}(1,r)$. They are either fibrations onto normal surfaces such that the general fibers are isomorphic to $\G(1,r)$ or the grassmannian $\mathbb{G}(1,r+1)$. The cases $r=2$ and $r=3$ are also considered in the more general context of varieties swept out by codimension two linear spaces or quadrics.

description: The wide range of drinking vessels developed by potters since the Geometric period offers one of the best indications of the particular value of the symposium in the ancient Greek world. So much creativity is not surprising, given the high appreciation for the shapes of vases; comparable, if not even better, to the appreciation of the ceramics’ painted decoration. Among the vessels, the krater was undoubtedly the most significant, followed by the cup. The name of the krater makes explicit reference to its function, which was to mix pure wine, the alcohol content of which was particularly high in the ancient world, with water. Drinking wine mixed with water was a fundamental rule of the symposium, well reflected in the centrality of the krater in relation to the encircling participants reclining on klinai. Greek painted pottery is characterized by a marked tendency for self-reference. Symposium and komos scenes are thus often represented on drinking vessels, and these scenes are an appropriate occasion for showcasing the vessels, and pointing out their association with the elite. keywords | Dionysus; Sicily; Ritual;Greek culture; Mythology; Symposium; Pots; Iconography.

description: We present and analyze a model of the frequency of severe terrorist attacks, which generalizes the recently proposed model of Johnson et al. This model, which is based on the notion of self-organized criticality and which describes how terrorist cells might aggregate and disintegrate over time, predicts that the distribution of attack severities should follow a power-law form with an exponent of alpha=5/2. This prediction is in good agreement with current empirical estimates for terrorist attacks worldwide, which give alpha=2.4 \pm 0.2, and which we show is independent of certain details of the model. We close by discussing the utility of this model for understanding terrorism and the behavior of terrorist organizations, and mention several productive ways it could be extended mathematically or tested empirically.

description: The essay by Horst Bredekamp and Claudia Wedepohl, Warburg, Cassirer und Einstein im Gespräch (Wagenbach, Berlin 2015) deals with the meeting of the Kulturwissenschaftler Aby Warburg and the physicist Albert Einstein which took place on initiative of the first scholar on September 4th 1928 in Scharbeutz. The main issue of the meeting was Kepler's discovery of the elliptical orbit of the planet Earth by means of a mental experiment, i.e. the observation of the Earth from Mars, a discovery which introduced a new cosmic conception whose emergence disrupted the Platonic world harmony. The present review strives to underline the concealed traces of the polar conflict detected by Warburg in Einstein's theoretical attitude between the two above-mentioned conceptions of the cosmos, the magic-mythical and the mathematic-physical one.
title: The Effect of Deposition from Static Rocket Tests on Immature Corn, Alfalfa, and Winter Wheat

description: Orbital ATK tests horizontally restrained solid rocket motors (SRMs) in Promontory, Utah, USA. During SRMs tests, an estimated 1.5 million kg (~3.3 million lbs.) of entrained soil and combustion products (mainly aluminum oxide, gaseous hydrogen chloride, and water) are deposited over a wide area. Local farmers have expressed concerns regarding the deposition of this material, referred to as Test Fire Soil (TFS), on crops surrounding the test site.
Greenhouse studies of mature corn and alfalfa (54 days to harvest) exposed to a worse case TFS deposition density to soil (3200-g/m2) resulted in reductions in germination and plant growth. Application of TFS only on leaves caused visual changes in leaf appearance (e.g. “burning”) but did not impact on growth. The visual damage to the leaves was thought to be caused by the high chloride in the TFS. The pH (measured from 2-10 in the field) of the TFS was also thought to be a potential cause of the visual damage.
Follow-up studies were conducted using younger corn, alfalfa and winter wheat (12-54 days from emergence), to evaluate the impact of a more typical TFS deposition density and application scenario. The relationship between deposition amount and the crop impact was also examined. Impact was evaluated by comparing the growth, tissue composition (focusing on chloride and aluminum) and chlorophyll content of controls relative to the treatments. The individual effects of chloride and pH on corn leaves were determined by monitoring visual appearance and chlorophyll content.
Leaves exposed to a typical TFS deposition loading (70-g/m2) did not contain elevated chloride or aluminum levels relative to the controls. Higher TFS loadings (700-g/m2 and 3200-g/m2) resulted in significantly elevated chloride content in corn leaves at 29 days from emergence. Corn leaves treated with TFS at the 700-g/m2 loading 12 days from emergence had comparable chloride levels to controls. High and low pH and chloride solutions visually impacted corn leaves and reduced leaf chlorophyll.
This study indicated SRMs testing can be conducted under typical conditions during the juvenile growth stages of field corn, alfalfa, and winter wheat without adverse impact on crop yield and plant tissue composition.

description: We discuss the hypothesis of a fixed point for quantum gravity coupled to a scalar, in the limit where the scalar field goes to infinity, accompanied by a suitable scaling of the metric. We propose that no scalar potential is present for the dilatation symmetric quantum effective action at the fixed point. Dimensional reduction of such a higher dimensional effective action leads to solutions with a vanishing effective four-dimensional constant. Under rather general circumstances these are the only quasistatic stable solutions with finite four-dimensional gravitational constant. If cosmological runaway solutions approach the fixed point as time goes to infinity, the cosmological constant vanishes asymptotically. For our old Universe the fixed point is not yet reached completely, resulting in a tiny amount of dark energy, comparable to dark matter. We discuss explicitly higher dimensional geometries which realize such asymptotic solutions for $t\to\infty$. They include Ricci-flat spaces as well as warped spaces, potentially with singularities.

description: The Bear River contributes more water to the eastern Great Basin than any other river system. It is also the most significant source of water for the burgeoning Wasatch Front metropolitan area in northern Utah. Despite its importance for water resources for the region’s agricultural, urban, and wildlife needs, our understanding of the variability of Bear River’s stream flow derives entirely from the short instrumental record (1943–2010). Here we present a 1200-year calibrated and verified tree-ring reconstruction of stream flow for the Bear River that explains 67% of the variance of the instrumental record over the period from 1943 to 2010. Furthermore, we developed this reconstruction from a species that is not typically used for dendroclimatology, Utah juniper (Juniperus osteosperma). We identify highly significant periodicity in our reconstruction at quasi-decadal (7–8 year), multi-decadal (30 year), and centennial (>50 years) scales. The latter half of the 20th century was found to be the 2nd wettest (∼40-year) period of the past 1200 years, while the first half of the 20th century marked the 4th driest period. The most severe period of reduced stream flow occurred during the Medieval Warm Period (ca. mid-1200s CE) and persisted for ∼70 years. Upper-level circulation anomalies suggest that atmospheric teleconnections originating in the western tropical Pacific are responsible for the delivery of precipitation to the Bear River watershed during the October–December (OND) season of the previous year. The Bear River flow was compared to recent reconstructions of the other tributaries to the Great Salt Lake (GSL) and the GSL level. Implications for water management could be drawn from the observation that the latter half of the 20th century was the 2nd wettest in 1200 years, and that management for future water supply should take into account the stream flow variability over the past millennium.

description: The static and dynamic properties of a Cosserat-type lattice interface of finite thickness are studied, so that both displacements and rotational degrees of freedom are taken into account. The model allows considering interfaces with a beam-like microstructure and interfaces with finite size particles as particular cases. One-dimensional solutions describing shear and micro-rotations at the interface are obtained and discussed. Harmonic as well as localized solutions, and the properties of the interfaces as filters for elastic waves are investigated. It is shown that both systems with long- and short-wavelength localization may exist.
