description: Semi-arid ecosystems play an important role in regulating global climate with the fate of these ecosystems in the Anthropocene depending upon interactions among temperature, precipitation, and CO₂. However, in cool-arid environments, precipitation is not the only limitation to forest productivity. Interactions between changes in precipitation and air temperature may enhance soil moisture stress while simultaneously extending growing season length, with unclear consequences for net carbon uptake. This study evaluates recent trends in productivity and phenology of Inner Asian forests (in Mongolia and Northern China) using satellite remote sensing, dendrochronology, and dynamic global vegetation model (DGVM) simulations to quantify the sensitivity of forest dynamics to decadal climate variability and trends. Trends in photosynthetically active radiation fraction (FPAR) between 1982 and 2010 show a greening of about 7% of the region in spring (March, April, May), and 3% of the area ‘browning’ during summertime (June, July, August). These satellite observations of FPAR are corroborated by trends in NPP simulated by the LPJ DGVM. Spring greening trends in FPAR are mainly explained by long-term trends in precipitation whereas summer browning trends are correlated with decreasing precipitation. Tree ring data from 25 sites confirm annual growth increments are mainly limited by summer precipitation (June, July, August) in Mongolia, and spring precipitation in northern China (March, April, May), with relatively weak prior-year lag effects. An ensemble of climate projections from the IPCC CMIP3 models indicates that warming temperatures (spring, summer) are expected to be associated with higher summer precipitation, which combined with CO₂ causes large increases in NPP and possibly even greater forest cover in the Mongolian steppe. In the absence of a strong direct CO₂ fertilization effect on plant growth (e.g., due to nutrient limitation), water stress or decreased carbon gain from higher autotrophic respiration results in decreased productivity and loss of forest cover. The fate of these semi-arid ecosystems thus appears to hinge upon the magnitude and subtleties of CO₂ fertilization effects, for which experimental observations in arid systems are needed to test and refine vegetation models.
title: Visual Assessment of Rivers and Marshes: An Examination of the Relationship of Visual Units, Perceptual Variables and Preference
Creators: name: Ellsworth, John C.
Publisher: name: Utah State University
Year: 1982

description: The purpose of this research was to examine the relationship of two approaches to visual assessment of landscape--the qualitative descriptive inventory and the theoretically-based empirical perceptual preference approach. Three levels of landscape visual units based on bio-physical similarities (landscape units, setting units, and waterscape units) were identified in a marsh (CUtler Reservoir, Cache County , Utah), and its tributary streams. Color slide photographs were taken from five of the visual units. These slides were rated on a 5- point scale by panels of judges for the expression of four perceptual variables--coherence, complexity, mystery, and legibility. The same slides were rated on a 5-point scale by 98 respondents according to their preference for each slide. The relationship of the visual units, perceptual variables, and preference was evaluated by analytical and statistical procedures.
Results showed significant differences in the expression of the four perceptual variables between rivers and marshes and between setting units~ Both rivers and marshes were considered coherent when there were similarities in vegetation within the respective types; however, the strong horizontal organization of the marsh scenes necessary for coherence contrasted with the edge definition and orderliness considered necessary in rivers. Mystery was also related to similar factors in rivers and marshes (such as obscuring vegetation, particularly in the marsh) but the presence of riverbanks and bends in the river corridor had a distinct effect on mystery ratings in the river scenes . Complexity in both rivers and marshes was primarily dependent on diversity of vegetation and visual depth , but the number of different visual elements in river scenes also influenced complexity. Legibility was related to straight, enclosed and simple corridors in river images and to simple spaces with regular vegetation in marsh images. Fine textures and clear spatial definition enhanced legibility.
Preference ratings were significantly different between rivers and marshes, but not between river setting units or waterscape units. River scenes received higher preference ratings than marsh scenes. Mystery , complexity, and visual depth were especially important to preference. Demographic variables of age, sex, academic major, and home state did not significantly affect preference. Statistical analysis indicated each perceptual variable was an independent predictor, and that compared to visual units, perceptual variables were more strongly related to preference.

description: We investigate the behaviour of tensor fluctuations in Loop Quantum Cosmology, focusing on a class of scaling solutions which admit a near scale-invariant scalar field power spectrum. We obtain the spectral index of the gravitational field perturbations, and find a strong blue tilt in the power spectrum with $n_t \approx 2$. The amplitude of tensor modes are, therefore, suppressed by many orders of magnitude on large scales compared to those predicted by the standard inflationary scenario where $n_t \approx 0$.

title: Mineral and Chemical Content of the Deep-Water Sediment Sequences of Bear Lake, Utah-Idaho
Creators: name: Biesinger, James C.
Publisher: name: Utah State University
Year: 1973

description: Twenty-five piston cores 6 to 12 feet long were obtained from the deepwater sediments of Bear Lake, Utah-Idaho. Analyses of these cores revealed that the deep-water sediments of the lake are divided into two major sequences: a younger sequence rich in carbonate minerals, here called the carbonate sequence, and an older sequence rich in silicate minerals, referred to in this paper as the silt sequence. The carbonate sequence is composed of clay-sized quartz, aragonite, calcite, dolomite, montmorillonite, illite, kaolinite, chlorite, and amorphous material. The silt sequence consists of both silt- sized and claysized particles of quartz, calcite, dolomite, montmorillonite, illite, kaolinite, chlorite, and amorphous material. Aragonite is absent in the silt sequence. The carbonate sequence is rich in ostracod exoskeletons and pollen grains. Small quantities of woody material and dark, organic-rich wnes occur within the silt sequence. Chemical analyses for Mg, Ca, Fe, Mn, K, Zn, Na , and Sr were reformed on the sediments. Unusually high concentrations of Fe (8.25 percent) were found in the silt sequence, and of Sr (0 .110 percent), in the carbonate sequence. Isotopic analyses for o18 and c13 in the lake sediments indicate that formation of the authigenic carbonate minerals occurred under normal lake-bottom conditions.
From the data collected, the following conclusions or inferences are made. The carbonate sequence was deposited in water depths similar to, or greater than, those of the present. Within this sequence, aragonite is precipitating at present from solution in such quantities that it is responsible for the inversion of the average Ca/ Mg mole ratio of inflowing water of 2:1 to a Ca/ Mg mole ratio of 1:5 in the lake water. The high concentration of Mg +2 and possible high concentration of Sr+2 in the lake water have resulted in conditions favorable for development of protodolomite. Atypical X-ray diffraction patterns for calcite and dolomite, and the relative abundances of aragonite, calc ite, and dolomite reveal that protodolomite probably is, or has been, forming in Bear Lake.
The silt sequence was deposited in water shallow enough for rooted plants to establish themselves . In this shallow environment detrital sediments rich in kaolinitic clay derived from the· Bear Lake Plateau were altered to sediments rich in montmorillonitic clay and amorphous materials.
The sharp contact between the silt sequence and the overlying carbonate sequence apparently represents abrupt termination of widespread swampy depositional conditions in the Bear Lake graben, caused by flooding, which possibly resulted from the most recent major episode of downfaulting of Bear Lake Valley.

description: Objective: Ultrasound-elastography (US-E) appears to be a helpful tool for the diagnosis of thyroid cancer. In acromegaly multinodular goiter is a common occurrence while the prevalence of thyroid cancer is still debated. Aims were to evaluate thyroid nodules in acromegaly and to establish the accuracy of US-E in providing information on their nature, using cytological analysis as a reference. Subjects and Methods: US-E was applied to 90 nodules detected in 25 acromegalic patients and to 94 nodules found in 31 non acromegalic goitrous subjects. The lesions were classified according to the elastographic scores (ES) as soft (ES 1-2) or hard (ES 3-4). FNAC could be performed in 60.8% of hard nodules in acromegalic patients and in 86.7% of hard nodules in controls. Results: The prevalence of hard nodules in patients with active acromegaly (68.9%) was greater, though not to a statistically significant extent, than that observed in cured (44.4%) and controlled (52.5%) patients. Citology revealed malignancy or suspect malignancy in none of the nodules of acromegalic patients. Conclusions: This study has demonstrated a high prevalence of stiff thyroid nodules in acromegaly, greater than that found in non acromegalic goitrous subjects. Such nodules, appeared not to be malignant and are probably of fibrous nature. Thus, US-E appears to be of limited value for the diagnosis of thyroid cancer in acromegaly.

description: Introduction Influenza is a major concern in hospitals, including the emergency department (ED), mainly because of a high risk for ED personnel to acquire and transmit the disease. Although influenza vaccination is recommended for health care workers, vaccination coverage is low. Methods This survey was conducted in the 2016/2017 and 2020/2021 influenza seasons. Questionnaires were sent to ED personnel in 12 hospitals in Bavaria, South-Eastern Germany. The response rates were 62% and 38% in 2016/2017 and 2020/2021, respectively. Data were compared between the two seasons as well as between vaccinated and not vaccinated respondents in 2020/2021. Results Significantly more ED personnel reported having been vaccinated in the 2020/2021 season. Factors associated with vaccination coverage (or the intention to get vaccinated) were profession (physician / medical student), having been vaccinated at least twice, the availability of an influenza vaccination on site (in the ED) as well as the COVID-19 pandemic. Additionally, significant differences in the assessment and evaluation of influenza, its vaccination side effects and ethical aspects were found between vaccinated and not vaccinated ED personnel in 2020/2021. Unvaccinated respondents estimated higher frequencies of almost all potential vaccination side effects, were less likely to accept lay-offs if employees would not come to work during an influenza pandemic and more likely to agree that work attendance should be an employee´s decision. Vaccinated participants instead, rather agreed that vaccination should be mandatory and were less likely to consider job changes in case of a mandatory vaccination policy. Conclusion The COVID-19 pandemic might have contributed to a higher influenza vaccination rate among ED workers. Vaccination on site and interventions targeting the perception of influenza vaccination and its side effects may be most promising to increase the vaccination coverage among ED personnel.

A recent result of Stanley (arXiv:0807.0383) says that for certain functions G defined on the set Y of all Young diagrams, the average of G with respect to M_n depends on n polynomially. We propose two other proofs of this result together with a generalization to the Jack deformation of the Plancherel measure.

Food habits in relation to the ecology and population dynamics of blue grouse.
Creators: name: King, Richard Dennis
Publisher: name: University of British Columbia
Year: 2011

description: The late spring and slimmer diet of blue grouse on lowland breeding ranges on Vancouver Island was determined by examination of the contents of 875 crops taken from birds collected on 3 study areas in the years 1950 through 1952 and 1957 through 1966. The spring and early summer diet of males was mostly conifer needles, while adult females ate mainly leaf material and flowers during the same period. The food of chicks was mainly invertebrates until the birds reached the age of approximately three weeks, at which time plant material formed the greater portion of the diet. In late summer the diet of both adult and juvenile grouse was primarily fruits and seeds of trailing blackberry, salal, huckleberry, and other plants. Selection of plant foods occurred at the time of ovulation and moult. As a result, the protein and mineral content of the diet was highest during periods of greatest need. No apparent differences in the spring diet of females were found which could be related to poor early survival of chicks, or to a delayed hatch in 1962. The various food types were eaten in similar relative proportions by adult and yearling grouse, and differences in reproductive performance of these two age classes could not be related to the diet of the grouse. The altitudinal migration of blue grouse in late summer and autumn does not appear to be related to the availability or condition of the food supply at the time of departure of the birds.
title: Coprecipitation of Phosphorus With Calcium Carbonate in Bear Lake, Utah - Idaho

Publisher: name: Utah State University
Year: 1985

description: Monitoring of Bear Lake was conducted in 1981 and 1982 to describe the current limnology and trophic state of the lake. The nutrientt loadings of various parameters were measured from April, 1981 through June, 1982. The rate of coprecipitation of phosphorus was determined for different initial phosphorus concentrations by use of non-algal assays. Algal bioassays with Selenastrum capricornutum were used to determine the reduction in potential algal biomass as a result of the coprecipitation of phosphorus.
The lake exhibit-.ed chemical characteristics indicative of mesotrophy or eutrophy. Total phosphorus values averaged 11μg/1 for 1981 and 20 μg/1 for 1982. A hypolimnetic accumulation of phosphorus was also not:ed for the stratified periods. Addittionally, hypolimnetic oxygen deficit values were indicative of mesotrophy in 1981 and eutrophy in 1982. The chlorophyll concentrations were characteristic of oligotrophic conditions during both years however. Phosphorus was found to be limiting production approximately 85% of the year.
The Bear River Contributed approximately 60% of the total phosphorus loading to the lake in 1981 and 50% in 1982. Overall, the total phophorus loading increased 195% between the dry year, 1981, and the wet year, 1982. Vollenweider's (1976) phosphorus loading model described the loading to Bear Lake as indicative of mesotrophic conditions in 1981 and eutrophic conditions in 1982.
Calcium and magnesium concentrations fluctuated widely throughout the year. The Mg:Ca molar ratio varied from 1:1 in the spring to 3.5:1 in the fall. Total hardness values did not vary in response to the changing ionic concentrations and this was attributed to preferential replacement of precipitated calcium by the Bear River inflow.
Non-algal assays quantified the removal of phosphorus by coprecipitation at increasing initial phosphorus by concentration. The rate of removal initial decreased substantially as phosphorus levels increased with a shift in reaction order from second order to first order noted at approximately 50 μg/1. Predictive models were derived from the initial assays and verified with data from a separate experiment which use filtered Bear Lake water. The models accurately predicted the amount of phosphorus removed by coprecipitation at all phosphorus levels.
Algal bioassays in synthetic Bear Lake and soft-water media were used to evaluate the efficiency of the coprecipitation mechanism when in competition with algae for phosphorus. An average reduction in biomass of 40% was noted between the media at similar nutrient levels.

description: Conventional descriptions of transverse waves in an elastic solid are limited by an assumption of infinitesimally small gradients of rotation. By assuming a linear response to variations in orientation, we derive an exact description of a restricted class of rotational waves in an ideal isotropic elastic solid. The result is a nonlinear equation expressed in terms of Dirac bispinors. This result provides a simple classical interpretation of relativistic quantum mechanical dynamics. We construct a Lagrangian of the form L=-E+U+K=0, where E is the total energy, U is the potential energy, and K is the kinetic energy.

title: Bioavailable Phosphorus in the Bear River System, Utah
Creators: name: Barker, Kenneth Warren
Publisher: name: Utah State University
Year: 1988

description: The bioavailable fraction of phosphorus (BAP) in the lower Bear River system waters was investigated. BAP plays a critical role as the limiting nutrient for algal production and eutrophication in proposed reservoirs in the Bear River system. The Bear River system has a hardness rang ing between 180-240 rng/L as CaC03 which significantly affects BAP.
BAP estimation was done by a modified Selenastrum capricornutum Printz Algal Assay Bottle Test. The algal bioassay is considered the best estimator of BAP because no chemical tests or i ndicator parameters are available. Autoclaving and UV radiation were found to be unacceptable means for sterilization because of phosphorus precipitation and inability to kill all the protozoa, respectively. Whole water samples were sterilized by gamma radiation . Hydrogen peroxide formed by gamma radiation was minimized by sparging with nitrogen gas , and adding peroxidase to remove low hydrogen peroxide concentrations. Soluble reactive phosphorus concentrations changed during radiation.
The algal photosynthetic consumption of co2 in the assay procedure raised the pH from 8 to as high as 10, which resulted in significant quantities of phosphorus precipitating with calcium and becoming unavailable. To minimize the effects of precipitation, the following recommendations are made : (1) bubble the bioassay flask with a C02/air gas mixture to minimize pH increase ; and (2) use a high inoculum (105 cells/ml) of S . capricornutum that have been phosphorus starved for several days to maximize luxury uptake.
Bioavailable phosphorus was estimated for each of the sources in Cache County. There are three major point sources (Logan, Hyrum, and Preston wastewater treatment plants) that contribute significant quantities of phosphorus . There are approximately 200 feedlots in the Cache Valley, and approximately 744,000 acres of land in Cache County which contribute runoff to the Bear River system. In Cache County, point sources contribute 2 8 , 20 0 ( 4 6%) kg BAP /yr, livestock runoff contributes 2,500 (4%) kg BAP/yr, and land runoff contributes 28,600 to 33,600 (50%) kg BAP/yr. Bioavailable phosphorus from land runoff was calculated by using export coefficients, which are usually accurate within a factor of two.
A comprehensive phosphorus management plan is required to reduce available phosphorus from all sources to minimize algal blooms in the receiving waters.

title: Anglers' Attitudes Toward the Fisheries Management Policies of the Logan and Blacksmith Fork Rivers, Utah
Creators: name: Riley, Larry Edwin
Publisher: name: Utah State University
Year: 1987

description: In the summer of 1986, anglers along three sections of the Logan and Blacksmith Fork Rivers, Utah were surveyed as to their attitudes toward fish stocking, habitat improvement, and wild trout management policies. Information concerning socio-demographic characteristics and ang ling values were ascertained as well. Data were cross tabulated to determine which of the variab les influence anglers' attitudes toward spec ifi c fisheries manage ment policies and the type of angling opportunity provided.
The analysis of data s how e d differences between the types of anglers using the three sample sections. The data showed that variables such as preferred angling method, preferred water type, number of fishing trips taken this year, age, importance of keeping fish, and whether an angler emphasizes catching a large number of fish or large fish, can influence anglers ' attitudes toward fisheries management policies.
The ungrouped data showed that the anglers sampled preferred: to catch brown or cutthroat trout; fish stocking to be limited to waters which have little or no natural reproduction or production; larger (14 inch) catchable size trout to be stocked even if it means a smaller number of fish will be stocked; the State to emphasize habitat improvement right along with fish stocking in their management plan; and the continuation of the policy to provide a limited amount of 11 Wild trout., regulated waters for angling variety.

description: Clostridium perfringens (CP) was evaluated as an additional indicator in assessing impacts and sources of microbial pollution in the Idaho-Utah Cache Valley . Point , nonpoint, river water, and animal fecal samples were analyzed for CP, total coliforms, fecal collforms, and fecal streptococci.
Monthly river samples consistently contained /100 mL , but concentrations of the other indicators varied significantly by location and date. Two sample stations consistently had CP concentrations greater than 20 / 100 mL . One of these stations was influenced by an upstream wastewater discharge . Chlorinated effluent from this trickling filter plant contained greater than 103 CP / 100 mL, but met a 400 FC/100 mL discharge standard. A consistent decrease in CP concentrations in samples taken downstream from this wastewater source were fo und, despite significant impact from adjacent nonpoint pollution. Lagoon and oxidation ditch wastewater effluents sampled contained/100 mL.
Nonpoint sources sampled (e.g . , cattle feedlot runoff) contained / 100 mL and 102-104/100 mL coliforms and fecal streptococcus. Cattle, horse, and sheep feces analyzed contained 104-107/g coliforms and fecal streptococcus, but less than 102 CP/g. Nonpoint pollution from such animals may contribute significant coliforms and streptococci but not CP. Wastewater treatment effluents may or may not contain elevated levels of CP depending on factors such as wastewater residence time and particular treatment process employed. The occurrence of relatively high, i.e., >102 CP/100 mL, in areas impacted by nonpoint sources may suggest a municipal wastewater input. Coliform and streptococci indicators may not be able to distinguish municipal or domestic microbial loading in the presence of nonpoint source interferences in many circumstances.

description: Growing neuropsychological and neurophysiological evidence suggests that the visual cortex uses parts-based representations to encode, store and retrieve relevant objects. In such a scheme, objects are represented as a set of spatially distributed local features, or parts, arranged in stereotypical fashion. To encode the local appearance and to represent the relations between the constituent parts, there has to be an appropriate memory structure formed by previous experience with visual objects. Here, we propose a model how a hierarchical memory structure supporting efficient storage and rapid recall of parts-based representations can be established by an experience-driven process of self-organization. The process is based on the collaboration of slow bidirectional synaptic plasticity and homeostatic unit activity regulation, both running at the top of fast activity dynamics with winner-take-all character modulated by an oscillatory rhythm. These neural mechanisms lay down the basis for cooperation and competition between the distributed units and their synaptic connections. Choosing human face recognition as a test task, we show that, under the condition of open-ended, unsupervised incremental learning, the system is able to form memory traces for individual faces in a parts-based fashion. On a lower memory layer the synaptic structure is developed to represent local facial features and their interrelations, while the identities of different persons are captured explicitly on a higher layer. An additional property of the resulting representations is the sparseness of both the activity during the recall and the synaptic patterns comprising the memory traces.

description: Polycyclic aromatic hydrocarbons (PAH) containing tar-mixtures pose a challenge for recycling road rubble, as the tar containing elements have to be extracted and decontaminated for recycling. In this preliminary study, tar, bitumen and minerals are discriminated using a combination of color (RGB) and Hyperspectral Short Wave Infrared (SWIR) cameras. Further, the use of an autoencoder for detecting minerals embedded inside tar- and bitumen mixtures is proposed. Features are extracted from the spectra of the SWIR camera and the texture of the RGB images. For classification, linear discriminant analysis combined with a k-nearest neighbor classification is used. First results show a reliable detection of minerals and positive signs for separability of tar and bitumen. This work is a foundation for developing a sensor-based sorting system for physical separation of tar contaminated samples in road rubble.

description: The Church of Jesus Christ of Latter-day Saints, commonly referred to as the Mormon Church, is one of the few religious organizations in the world today that constructs temples, since its founding in the year 1830 these sacred edifices have exerted a definite influence upon its members, and have played an important part in the religious activities of the church and fulfilled a definite role in its gospel teachings. A number of these temples have been constructed under varying circumstances in different parts of the country where the need has arisen. These buildings were more than houses of worship, for the erection of churches has taken place concurrently with the construction of these temples, to understand the relationship which these edifices hold to the doctrine and teachings of the church one must go back to the early days of the church and note the origin and development of the temple idea, as well as the place which it holds in the hearts of the members of the church.

description: Before Brigham Young College was founded in 1877, a variety of schools existed in Utah. The Mormons at first, and later the Protestants and Catholics made significant contributions to education in the territory. Education has always played an important role in the philosophy of the Mormon church. In the early days of church history, the Mormons founded schools in the places they settled. This policy continued when they settled in Utah.
title: Diel Vertical Migration and Feeding of Underyearling Bear Lake Sculpin Cottus extensus (Pisces, Cottidae)
Creators: name: Neverman, Darcy
Publisher: name: Utah State University

description: Underyearling Bear Lake sculpin exhibit a diel pattern of vertical migration throughout the pelagic region of Bear Lake (Utah-Idaho) until they are approximately 22 mm standard length. Individuals move from the bottom of the lake (5° C) during the day into the water column (13-16° C) at night. The migration, however, is not related to feeding. Although the dominant copepod in the water column, Epischura nevadensis, do undergo a similar diel vertical migration, stomach analysis of juvenile sculpin captured by trawling shows that they do not feed in the water column. Instead, from July through October, their diet is dominated (70-93%) by benthic copepods and ostracods. Also, gut fullness of sculpin increases through the daylight period and decreases through the night, reaching minimum levels just before the dawn descent. Furthermore, feeding trials conducted in the laboratory show that juvenile sculpin feed most efficiently at light intensities found on the bottom (30-60m) of Bear Lake during the day. Feeding rate coefficients increase markedly from 1013 photons m-2S-1 until peaking at intermediate intensities of 1016 photons m-2S-1 and then decline at higher light levels. Although they do not migrate to feed, the movement into the warmer water appears to increase the sculpin's digestion rate, thereby allowing continued feeding during the day. This supports the hypothesis that diel vertical migration in Bear Lake sculpin is a thermoregulatory strategy that increases growth rate.

description: Despite increasing prevalence of dual sensory impairment (DSI) with increasing age in the United States (US), there is little attention on its disease burden. The objective of this study was to assess the association between DSI and all-cause hospitalization in California Medicare beneficiaries. This cross-sectional study was conducted among all U.S. California Medicare beneficiaries from 2015. Sensory impairment status includes DSI, visual impairment only (VIO), and hearing impairment only (HIO). Hospitalization was defined as at least one inpatient claim in the Inpatient Claim database. Multivariable logistic regression analyses were used to calculate odds ratios (ORs) of hospitalization for DSI. The study sample included 2,574,641 California Medicare beneficiaries. There were 0.1% (n = 3,055), 0.7% (n = 16,896), and 7.1% (n = 181,838) of beneficiaries who had DSI, VIO, and HIO, respectively. Patients aged 85+ years had the highest proportion in all three sensory impairment groups, especially in the DSI group. Both unadjusted and fully adjusted models revealed a higher odds of inpatient stay for beneficiaries with DSI compared with NSI (unadjusted OR = 2.66; 95% CI = 2.46–2.87; fully adjusted OR = 1.41; 95% CI = 1.30–1.54). Subjects with VIO also demonstrated higher odds of hospital admission compared with NSI (fully adjusted OR = 1.48; 95% CI = 1.42–1.53). In a cohort of U.S. California Medicare beneficiaries, subjects with DSI or VIO had a higher odds of hospitalization compared to those with NSI.
Modular differential equations for torus one-point functions

description: It is shown that in a rational conformal field theory every torus one-point function of a given highest weight state satisfies a modular differential equation. We derive and solve these differential equations explicitly for some Virasoro minimal models. In general, however, the resulting amplitudes do not seem to be expressible in terms of standard transcendental functions.

Slow light, open cavity formation, and large longitudinal electric field on slab waveguide made of indefinite permittivity materials

description: The optical properties of slab waveguides made of indefinite permittivity ($\vep$) materials (IEM) are considered. In this medium the transverse permittivity is negative while the longitudinal permittivity is positive. At any given frequency the waveguide supports an infinite number of transverse magnetic (TM) eigenmodes. For a slab waveguide with a fixed thickness, at most only one TM mode is forward-wave. The rest of them are backward waves which can have very large phase index. At a critical thickness, the waveguide supports degenerate forward- and backward-wave modes with zero group velocity. Above the critical thickness, the waveguide supports complex-conjugate decay modes instead of propagating modes. The presence of loss in IEMs will lift the degeneracy, resulting in modes with finite group velocity. Feasible realization is proposed. The performance of IEM waveguide is analyzed and possible applications are discussed which are supported by numerical calculations. These slab waveguides can be used to make optical delay lines in optical buffers to slow down and trap light, to form open cavities, to generate strong longitudinal electric fields, and as phase shifters in optical integrated circuits.

title: Future Water Demand in Cache Valley, Utah
Creators: name: Saunders, Chris C.
Publisher: name: Utah State University
Year: 1993

description: The present investigation examined the current water demand characteristics and the future water demand of Cache Valley, Utah for the time period of 1990-2010. The demand attributable to agriculture and seven nonagricultural economics sectors was determined and forecasts were performed based on those demand values.
Linear regression, extrapolation, and alternative futures forecasting methods were applied and the various results compared against each other. Three different scenarios were calculated for residential demand to represent different sources and composition of demand information. It was determined that consideration of water demand data excluding Logan City provided the best statistical description of water demand.
A discussion of the probable changes in the three water demand components, agriculture, industrial and residential, addressed issue of conservation and change of use patterns which would impact on the need for future development of new water supplies to meet the forecast demand for Cache Valley, Utah.
Studies of the sheep neurophypophysis during pregnancy and foetal development

description: The biological activities of the neurohypophyses of pregnant and embryonic sheep, Ovis aries were studied. The levels of hormonal activities of the neurohypophyses varied with the stage of pregnancy, and were always lower than levels in the control (non-pregnant) glands. Chemical studies of the purified oxytocic and vasopressor moieties of the pregnant sheep have indicated that these agents are oxytocin and arginine vasopressin. An increase of biologically active agents of the posterior pituitary was detected concomitant with embryonic development. The amount of vasopressor activity greatly surpassed the oxytocic activity in the neurohypophyses of foetal sheep all through gestation, but the difference became smaller with the advancement of intrauterine life. Pharmacological and chemical studies indicated oxytocin and arginine vasopressin as the active peptides of the foetal neurohypophysis. In addition to these two neurohypophysial peptides characteristic of the mammals, the presence of a third peptide was indicated. Pharmacological studies indicate that this third neurohypophysial peptide of the foetuses may be arginine vasotocin, the antidiuretic principle of lower vertebrates.

description: In this paper, we discuss stochastic comparisons of lifetimes of series and parallel systems when the components are exponentiated location-scale models under random shocks. The results established here are developed in two directions. First, the comparisons are carried out with respect to usual stochastic ordering by using the concept of vector majorization for series and parallel systems. Next, when the matrix of parameters changes to another matrix of parameters in the sense of multivariate chain majorization, we study the usual stochastic order of the smallest order statistics when each component receives a random shock.
