description: This composite manuscript contains acts of the delegation of the Council of Basel to Constantinople, declarations of protest, and notarial instruments. It previously had a limp binding made from a 1436 marriage dispensation charter, which today is stored separately. The majority of the manuscript consists of a report on the mission to Greece and is partially based on Jakob Hüglin’s notes conserved in the Hs 3 of the Episcopal Archive of the Bishopric of Basel in Solothurn. Jakob Hüglin (ca. 1400–1484) was active at the Council of Basel as notary from 1432, and as scribe from 1435. In 1437, together with the notary Dietrich Winckelman, he accompanied the delegation to Constantinople. The trip lasted a year, until February 1438. The composite manuscript consists of 17 fascicules, which are sewn together and were copied by different scribes.

The Canted Spiral: An Exact Ground State of XXZ Zigzag Ladders

description: We derive the exact ground states for a one dimensional family of $S=1/2$ XXZ Hamiltonians on the zigzag ladder. These states exhibit true long range spiral order that spontaneously breaks the U(1) invariance of the Hamiltonian. Besides breaking a continuous symmetry in $d=1$, this spiral ordering has a ferromagnetic component along the symmetry axis that can take any value between zero and full saturation. In this sense, our canted spiral solutions are a generalization of the SU(2) Heisenberg ferromagnet to non-zero ordering wave-vectors of the transverse spin components. We extend this result to the $d=2$ anisotropic triangular lattice.

description: Short-lived radionuclides, such as 26Al and 60Fe, are tracers of star formation. Therefore, their abundances can unravel the recent star formation history of the host galaxy. In view of future gamma-ray surveys, we predict the masses and fluxes of these two elements in the Large Magellanic Cloud (LMC) using new chemical evolution models. Our best model reproduces the abundance patterns of alpha/Fe ratios, the gas mass, the average metallicity, the present time supernova and nova rates observed in LMC. We show three main results: i) the best model for the LMC suggests a star formation rate very mild at the beginning with a recent burst, and a Salpeter-like initial mass function. ii) The predicted mass of 26Al is 0.33 M_Sun, 2/3 produced by massive stars and 1/3 by novae. iii) The predicted mass of 60Fe is 0.44 M_Sun, entirely produced by massive stars. This result suggests a larger fraction of 60Fe, at variance with the Milky Way. The explanation for this lies in the adopted initial mass function, that for the LMC contains more massive stars than for the Milky Way. These predictions can be useful for the COSI-SMEX mission planned for launch in 2027. The expected gamma-ray line fluxes for the 1.809 MeV line of 26Al and the 1.173 and 1.332 MeV lines of 60Fe are in the range of (0.2-2.7)x10^-6 ph cm^-2 s^-1 and (0.7-2.8)x10^-7 ph cm^-2 s^-1, respectively. This new instrument could have the sensitivity to detect the upper end of the predicted 1.8 MeV flux within its nominal two-year mission.

description: The merger process of a binary black hole system can have a strong impact on a circumbinary disk. In the present work we study the effect of both central mass reduction (due to the energy loss through gravitational waves) and a possible black hole recoil (due to asymmetric emission of gravitational radiation). For the mass reduction case and recoil directed along the disk's angular momentum, oscillations are induced in the disk which then modulate the internal energy and bremsstrahlung luminosities. On the other hand, when the recoil direction has a component orthogonal to the disk's angular momentum, the disk's dynamics are strongly impacted, giving rise to relativistic shocks. The shock heating leaves its signature in our proxies for radiation, the total internal energy and bremsstrahlung luminosity. Interestingly, for cases where the kick velocity is below the smallest orbital velocity in the disk (a likely scenario in real AGN), we observe a common, characteristic pattern in the internal energy of the disk. Variations in kick velocity simply provide a phase offset in the characteristic pattern implying that observations of such a signature could yield a measure of the kick velocity through electromagnetic signals alone.

description: Pickup ions (PUIs) play a crucial role in the heliosphere, contributing to the mediation of large-scale structures such as the distant solar wind, the heliospheric termination shock (HTS), and the heliopause. While magnetic reconnection is thought to be a common process in the heliosphere due to the presence of heliospheric current sheets, it is poorly understood how PUIs might affect the evolution of magnetic reconnection. Although it is reasonable to suppose that PUIs decrease the reconnection rate since the plasma beta becomes much larger than $1$ when PUIs are included, we show for the first time that such a supposition is invalid and that PUI-induced turbulence, heat conduction, and viscosity can preferentially boost magnetic reconnection in heliospheric current sheets in the distant solar wind. This suggests that it is critical to include the effect of the turbulence, heat conduction, and viscosity caused by PUIs to understand the dynamics of magnetic reconnection in the outer heliosphere.

description: We present results from the first molecular line survey to search for the fundamental complex organic molecule, methanol (CH$_{3}$OH), in 14 Class 0/I proto-brown dwarfs (proto-BDs). IRAM 30-m observations over the frequency range of 92-116 GHz and 213-280 GHz have revealed emission in 14 CH$_{3}$OH transition lines, at upper state energy level, E$_{upper}\sim$7-49 K, and critical densities, $n_{crit}$ of 10$^{5}$ to 10$^{9}$ cm$^{-3}$. The most commonly detected lines are at E$_{upper} <$ 20 K, while 11 proto-BDs also show emission in the higher excitation lines at E$_{upper}\sim$21-49 K and $n_{crit}\sim$10$^{5}$ to 10$^{8}$ cm$^{-3}$. In comparison with the brown dwarf formation models, the high excitation lines likely probe the warm ($\sim$25-50 K) corino region at $\sim$10-50 au in the proto-BDs, while the low-excitation lines trace the cold ($<$ 20 K) gas at $\sim$50-150 au. The column density for the cold component is an order of magnitude higher than the warm component. The CH$_{3}$OH ortho-to-para ratios range between $\sim$0.3-2.3. The volume-averaged CH$_{3}$OH column densities show a rise with decreasing bolometric luminosity among the proto-BDs, with the median column density higher by a factor of $\sim$3 compared to low-mass protostars. Emission in high-excitation (E$_{upper}>$ 25 K) CH$_{3}$OH lines together with the model predictions suggest that a warm corino is present in $\sim$78\% of the proto-BDs in our sample. The remaining show evidence of only the cold component, possibly due to the absence of a strong, high-velocity jet that can stir up the warm gas around it.

description: Quantum computing devices are believed to be powerful in solving the prime factorization problem, which is at the heart of widely deployed public-key cryptographic tools. However, the implementation of Shor's quantum factorization algorithm requires significant resources scaling linearly with the number size; taking into account an overhead that is required for quantum error correction the estimation is that 20 millions of (noisy) physical qubits are required for factoring 2048-bit RSA key in 8 hours. Recent proposal by Yan et al. claims a possibility of solving the factorization problem with sublinear quantum resources. As we demonstrate in our work, this proposal lacks systematic analysis of the computational complexity of the classical part of the algorithm, which exploits the Schnorr's lattice-based approach. We provide several examples illustrating the need in additional resource analysis for the proposed quantum factorization algorithm.

description: Considering the tangent plane at a point to a surface in the four-dimensional Euclidean space, we find an invariant of a pair of two tangents in this plane. If this invariant is zero, the two tangents are said to be conjugate. When the two tangents coincide with a given tangent, then we obtain the normal curvature of this tangent. Asymptotic tangents (curves) are characterized by zero normal curvature. Considering the invariant of the pair of a given tangent and its orthogonal one, we introduce the geodesic torsion of this tangent. We obtain that principal tangents (curves) are characterized by zero geodesic torsion. The invariants $\varkappa$ and $k$ are introduced as the symmetric functions of the two principal normal curvatures. The geometric meaning of the semi-sum $\varkappa$ of the principal normal curvatures is equal (up to a sign) to the curvature of the normal connection of the surface. The number of asymptotic tangents at a point of the surface is determined by the sign of the invariant $k$. In the case $k=0$ there exists a one-parameter family of asymptotic lines, which are principal. We find examples of such surfaces ($k=0$) in the class of the general rotational surfaces (in the sense of Moore). The principal asymptotic lines on these surfaces are helices in the four-dimensional Euclidean space.

description: We study the effect of homogeneous noise on the escape rate of strongly chaotic area-preserving maps with a small opening. While in the noiseless dynamics the escape rate analytically depends on the instability of the shortest periodic orbit inside the hole, adding noise overall enhances escape, which, however, exhibits a non-trivial response to the noise amplitude, featuring an initial plateau and a successive rapid growth up to a saturation value. Numerical analysis is performed on cat maps with a hole, and the salient traits of the response to noise of the escape rate are reproduced analytically by an approximate model.

description: We discuss the generation and the long-time persistence of entanglement in open two-qubit systems whose reduced dissipative dynamics is not apriori engineered but is instead subjected to filtering and Markovian feedback. In particular, we analytically study 1.) whether the latter operations may enhance the environment capability of generating entanglement at short times and 2.) whether the generated entaglement survives in the long-time regime. We show that, in the case of particularly symmetric Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) it is possible to fully control the convex set of stationary states of the two-qubit reduced dynamics, therefore the asymptotic behaviour of any initial two-qubit state. We then study the impact of a suitable class of feed-back operations on the considered dynamics.
From fact to value

description: It is my aim to present an argument against the view that there is a strict dualism of FACTS on the one hand and DECISIONS or DEMANDS on the other and to show that there are cases in which an OUGHT can be derived from an IS. I begin by examining the nature of facts in order to determine what they are and what connection there may be between them and events, situations or states of affair. I next examine the question as to whether there is warrant to stipulate a philosophically technical sense of 'pure fact' or the 'merely factual’ and give consideration to the relevance of the concepts of explanatory power and objectivity to this question, concluding that these concepts do not appear to furnish such a warrant. There follows an argument in support of my opinion that statements of fact presuppose viewpoints which are shared amongst men, thus presupposing in turn some form of community. By discussing several statements of fact and showing their dependence upon institutions or societal arrangements I attempt to support my denial of the claim that specifically MORAL premisses are ALWAYS required in order to derive demands or decisions from statements of fact. In considering several objections which a dualist might raise against my argument I deal with the question of genetic explanation of moral codes, with some of the possible OUTSIDER positions in respect of moral decisions or demands and with the requirement that rules of formal logic be observed in arriving at moral conclusions. Since I am not denying the strength in the dualist's position in insisting upon an analysis of statements of fact in an attempt to establish 'pure fact' or the 'merely factual' I next examine a restricted form of a dualistic view which deals with the distinction between descriptive and prescriptive contents in statements of fact. This shows that there are indeed sentences cast in the form of statements of fact which seem to have predominantly prescriptive content, and I concede the value of a dualistic analysis to bring this out. I claim that this does not militate against my argument as presented, that there are objective statements of fact from which by virtue of the viewpoint underlying them moral demands or decisions can be derived and that it would be extremely difficult to make intelligible the claim that they were not statements of FACT. In a speculative postscript I touch upon the problem of overriding moral demands.

description: During cluster mergers, the intracluster gas and member galaxies undergo dynamic evolution, but at different timescales and reach different states. We collect 24 galaxy clusters in quasi-equilibrium state as indicated by the X-ray image, and calculate the cluster orientations and three kinds of dynamical parameters, i.e., the normalized centroid offset, the sphere index and the ellipticity, for these clusters from the distributions of member galaxies and also the intracluster gas. We find consistent alignments for the orientations estimated from the two components. However, the three kinds of dynamical parameters indicated by member galaxies are systematically larger than those derived from the gas component, suggesting that the gas component is more relaxed than member galaxies. Differences of dynamical features between the intracluster gas and member galaxies are independent of cluster mass and concentration. We conclude that the intracluster gas reaches the dynamic equilibrium state earlier than the almost collisionless member galaxies.

title: Boron Movement in Soil Columns
Creators: name: Stucki, Joseph William
Publisher: name: Utah State University
Year: 1972

description: Three adsorption theories--Langmuir, B.E.T., and Freundlich--were applied to boron interaction with Aiken clay loam and Vernal sandy loam soils to determine which bests describes the system.
Column studies were conducted to obtain constants related to mass fluid flow and fluid dispersion within the column. An inert ion was used to obtain the pore volume and to calculate the fluid dispersion coefficient. These data were used to solve the material balance equation by the explicit numerical method developed by Lai for a digital computer. The output from the computer was a predicted profile boron distribution within the soil column.
The soil columns were undergoing saturated flow and 10 ppm boron solution was introduced at the top and allowed to flow for a specified period of time, at which time the column was segmented and analyzed for boron to obtain the experimental profile boron distribution within the soil column. The experimental and predicted profiles were compared.

The master equation case and structural information principle are derived. Then, the phenomenological description of the information transfer is presented. The extreme physical information (EPI) method is reviewed. As if marginal, the statistical interpretation of the amplitude of the system is given.

description: In this article, we investigate mismatch of renewable electricity production to demand and how this is affected by flexibility options on the supply side. We assess the impact of spatial and temporal smoothing on reliability of production and whether they can reduce risks of variation. As a case study we pick a simplified (partial) representation of the Norwegian electricity system and focus on wind power. We represent regional electricity production and demand through two stochastic processes: the wind capacity factors are modelled as a two-dimensional Ornstein-Uhlenbeck process and electricity demand consists of realistic base load and temperature-induced load coming from a deseasonalised autoregressive process. We validate these processes, that we have trained on historical data, through Monte Carlo simulations allowing us to generate many statistically representative weather years. For the investigated realisations (weather years) we study deviations of production from demand under different wind capacities, and introduce different scenarios where flexibility options like storage and transmission is available. Our analysis shows that simulated loss values are reduced significantly by cooperation and any mode of flexibility. Combining storage and transmission leads to even more synergies and helps to stabilise production levels and thus adequacy of renewable power systems.

description: We undertake the first targeted search at 1.5 GHz for radio emission from the variable $γ$-ray pulsar PSR J2021$+$4026. This radio-quiet pulsar assumes one of two stable $γ$-ray emission states, between which it transitions on a timescale of years. These transitions, in both $γ$-ray flux and pulse profile shape, are accompanied by contemporaneous changes to the pulsar's spin-down rate. A number of radio pulsars are known to exhibit similar correlated variability, which in some cases involves an emission state in which the radio emission ceases to be detectable. In this paper, we perform a search for radio emission from PSR J2021$+$4026, using archival radio observations recorded when the pulsar was in each of its emission/spin-down states. Using improved techniques, we search for periodic radio emission as well as single pulse phenomena such as giant radio pulses and RRAT-like emission. Our search reveals no evidence of radio emission from PSR J2021$+$4026. We estimate that the flux density for periodic emission from PSR J2021$+$4026 does not exceed 0.2 mJy at this frequency. We also estimate single-pulse flux limits for RRAT-like bursts and giant radio pulses to be 0.3 and 100 Jy respectively. We discuss the transitioning behaviour of PSR J2021$+$4026 in the context of pulsar glitches, intermittent pulsars and the increasingly common emission-rotation correlation observed in radio pulsars.

description: In two-tier networks -- comprising a conventional cellular network overlaid with shorter range hotspots (e.g. femtocells, distributed antennas, or wired relays) -- with universal frequency reuse, the near-far effect from cross-tier interference creates dead spots where reliable coverage cannot be guaranteed to users in either tier. Equipping the macrocell and femtocells with multiple antennas enhances robustness against the near-far problem. This work derives the maximum number of simultaneously transmitting multiple antenna femtocells meeting a per-tier outage probability constraint. Coverage dead zones are presented wherein cross-tier interference bottlenecks cellular and hotspot coverage. Two operating regimes are shown namely 1) a cellular-limited regime in which femtocell users experience unacceptable cross-tier interference and 2) a hotspot-limited regime wherein both femtocell users and cellular users are limited by hotspot interference. Our analysis accounts for the per-tier transmit powers, the number of transmit antennas (single antenna transmission being a special case) and terrestrial propagation such as the Rayleigh fading and the path loss exponents. Single-user (SU) multiple antenna transmission at each tier is shown to provide significantly superior coverage and spatial reuse relative to multiuser (MU) transmission. We propose a decentralized carrier-sensing approach to regulate femtocell transmission powers based on their location. Considering a worst-case cell-edge location, simulations using typical path loss scenarios show that our interference management strategy provides reliable cellular coverage with about 60 femtocells per cellsite.

Creators: name: Meyers, Theodore F.
Publisher: name: Utah State University
Year: 1972

description: Exponential rates of digestion are described for brown trout and whitefish for July, October, December (1969), and April (1970). The slope of the line fitted to the digestion data from each month was defined as the instantaneous rate of digestion and applied to an exponential growth model to determine the instantaneous consumption rate.
The digestion and consumption rates were applied to field measurements of percent fullness to determine the amount of food material ingested during a 24 hour period. Brown trout consumed 127, 24, 19, and 84 mean percent of their stomach capacity in the July, October, December, and April studies. Whitefish consumed 74, 21, 46, and 51 mean percent of their stomach capacity in the same respective study periods. Mean daily ration from four major collection periods was calculated on fish in the 50 gram to BOO gram size range. Brown trout daily ration varied between 1.35 percent and 2.59 percent. Whitefish daily ration varied between 0.44 percent and 0.83 percent.
Brown trout diets were quite variable with 44 percent of their caloric intake comprised of terrestrial invertebrates in October, 55 percent of the December calories comprised of fish eggs, and 39 percent of the April calories made up of Leptoceridae larvae.
Emerging imagoes were important items in the brown trout diets, contributing as much as 62 percent and not less than 11 percent of the numeric intake for one collection period.
Whitefish did not rely upon emerging imagoes as a significant food source. Their stomachs consistently contained mayflies, chironomids, and caddis larvae. Both fish species occasionally consumed substantial amounts of the large stonefly, Pteronarcys.

description: The Federal Government has placed stringent standards on the manufacturers of automobiles to control vehicle emissions. Few states standards have been set for used vehicles to insure the vehicle continues to meet this standard.
Studies have shown that vehicles that are properly tuned are emitting less harmful pollutants from the exhaust. Additional studies are needed to determine if cars are being adequately turned to meet exhaust emissions.
The study showed 93 per cent of the new 1971 model cars were not meeting the standard established by the Environmental Protection Agency. Eighty-seven per cent of the 1970 model cars and 83 per cent of the used 1971 model cars tested would not meet the same standards.
There was a very low correlation between emission level and the mileage driven since the vehicle was tuned indicating a need for more emphasis on tune-ups and maintenance of automobiles to meet emission standards.

Although the models tend to aggravate the Hubble tension a bit, they tend to reduce the $S_8$ tension, even in comparison with the constant viscosity case. Since similar to viscosity massive neutrinos suppress the power spectrum of matter on small length scales, considering them along with the viscous dark matter, we find that the neutrino mass range is tightened.

description: We study the evolutionary path of the Fornax cluster galaxy NGC$~$1436, which is known to be currently transitioning from a spiral into a lenticular morphology. This galaxy hosts an inner star-forming disc and an outer quiescent disc, and we analyse data from the MeerKAT Fornax Survey, ALMA, and the Fornax3D survey to study the interstellar medium and the stellar populations of both disc components. Thanks to the combination of high resolution and sensitivity of the MeerKAT data, we find that the $\textrm{H}\scriptstyle\mathrm{I}$ is entirely confined within the inner star-forming disc, and that its kinematics is coincident with that of the CO. The cold gas disc is now well settled, which suggests that the galaxy has not been affected by any environmental interactions in the last $\sim1~$Gyr. The star formation history derived from the Fornax3D data shows that both the inner and outer disc experienced a burst of star formation $\sim5$ Gyr ago, followed by rapid quenching in the outer disc and by slow quenching in the inner disc, which continues forming stars to this day. We claim that NGC$~$1436 has begun to effectively interact with the cluster environment 5$~$Gyr ago, when a combination of gravitational and hydrodynamical interactions caused the temporary enhancement of the star-formation rate. Furthermore, due to the weaker gravitational binding $\textrm{H}\scriptstyle\mathrm{I}$ was stripped from the outer disc, causing its rapid quenching. At the same time, accretion of gas onto the inner disc stopped, causing slow quenching in this region.

description: The global star formation rate has decreased significantly since z ~ 1, for reasons that are not well understood. Red-sequence galaxies, dominating in galaxy clusters, represent the population that have had their star formation shut off, and may therefore be the key to this problem.

description: Propagating patterns are used to transfer and process information in chemical and physical prototypes of unconventional computing devices. Logical values are represented by fronts of traveling diffusive, trigger or phase waves. We apply this concept of pattern based computation to develop experimental prototypes of computing circuits implemented in small modular robots. In the experimental prototypes the modular robots Cubelets are concatenated into channels and junction. The structures developed by Cubelets propagate signals in parallel and asynchronously. The approach is illustrated with a working circuit of a one-bit full adder. Complementarily a formalization of these constructions are developed across Sleptsov nets. Finally, a perspective to swarm dynamics is discussed.

description: Photoevaporative disc winds play a key role in our understanding of circumstellar disc evolution, especially in the final stages, and they might affect the planet formation process and the final location of planets. The study of transition discs (i.e. discs with a central dust cavity) is central for our understanding of the photoevaporation process and disc dispersal. However, we need to distinguish cavities created by photoevaporation from those created by giant planets. Theoretical models are necessary to identify possible observational signatures of the two different processes, and models to find the differences between the two processes are still lacking. In this paper we study a sample of transition discs obtained from radiation-hydrodynamic simulations of internally photoevaporated discs, and focus on the dust dynamics relevant for current ALMA observations. We then compared our results with gaps opened by super Earths/giant planets, finding that the photoevaporated cavity steepness depends mildly on gap size, and it is similar to that of a 1 Jupiter mass planet. However, the dust density drops less rapidly inside the photoevaporated cavity compared to the planetary case due to the less efficient dust filtering. This effect is visible in the resulting spectral index, which shows a larger spectral index at the cavity edge and a shallower increase inside it with respect to the planetary case. The combination of cavity steepness and spectral index might reveal the true nature of transition discs.

title: Nitrogen Movement Under Irrigated Corn as Influenced by Nitrogen Source and Rate
Creators: name: Muir, Douglas C.
Publisher: name: Utah State University
Year: 1972

description: The purpose of this study was to determine nitrogen movements under a fall applied fertilizer as affected by rate of application of fertilizer, type of fertilizer carrier, and by crop grown. Two nitrogen fertilizers, calcium nitrate and ammonium sulfate, were applied in the fall of 1970. The soil profile was sampled in the spring of 1971 and again in the fall of 1971. Nitrate-nitrogen from both the calcium nitrate and the ammonium sulfate applications was found to have moved significantly from the time of application to the time of spring soil sampling. Two effects from the high rate of both calcium nitrate and ammonium sulfate which had influenced nitrate-nitrogen location in the profile were observed. The first effect was a promoting of deep movement of nitrate nitrogen by the high rate of calcium nitrate. The second effect was a delay of deep leaching of nitrate-nitrogen by the high rate of ammonium sulfate.
The crop grown in the calcium nitrate plots was severely nitrogen deficient at all rates of fertilizer application. The corn grown in the ammonium sulfate plots at 150 pounds nitrogen per acre were nitrogen deficient to the same degree as the calcium nitrate plots. The crop in the high rate of ammonium sulfate plots looked quite good although some nitrogen deficiency symptoms did appear. Crop performance showed that severe leaching had taken place over the winter and through the growing season. This leaching was found to be affected by type of fertilizer carrier, application rate of fertilizer, and the crop grown. At the end of the growing season approximately half of the nitrate-nitrogen present in the soil profile in the spring was present in the fall after crop removal.
Closed systems refuting quantum-speed-limit hypotheses

description: Many quantum speed limits for isolated systems can be generalized to also apply to closed systems. This is, for example, the case with the well-known Mandelstam-Tamm quantum speed limit. Margolus and Levitin derived an equally well-known and ostensibly related quantum speed limit, and it seems to be widely believed that the Margolus-Levitin quantum speed limit can be similarly generalized to closed systems. However, a recent geometrical examination of this limit reveals that it differs significantly from most known quantum speed limits. In this paper, we show that, contrary to the common belief, the Margolus-Levitin quantum speed limit does not extend to closed systems in an obvious way. More precisely, we show that for every hypothetical bound of Margolus-Levitin type, there are closed systems that evolve with a conserved normalized expected energy between states with any given fidelity in a time shorter than the bound. We also show that for isolated systems, the Mandelstam-Tamm quantum speed limit and a slightly weakened version of this limit that we call the Bhatia-Davies quantum speed limit always saturate simultaneously. Both of these evolution time estimates extend straightforwardly to closed systems. We demonstrate that there are closed systems that saturate the Mandelstam-Tamm but not the Bhatia-Davies quantum speed limit.

title: Toward a Measurement of the Adequacy of Health Services in Rural Utah
Creators: name: Miller, Michael K.
Publisher: name: Utah State University
Year: 1972

description: The research reported in this thesis was an exploratory nature undertaken for the purpose of developing a measure of the adequacy of health services in three rural counties in Utah. The three counties included in the study area were Beaver, Piute, and Wayne.
Adequacy of health services in the three-county area was measured on the basis of (1) the general population's, or consumer's, perception of the adequacy of the existing services, (2) the professional's or provider's perception of the adequacy of the existing services, and (3) adequacy of the existing services determined by a comparison with an established standard.
The findings showed that major differences in the general population's perception of adequacy are present when controlling for county with the vast majority of the respondents in Piute and Wayne counties perceiving the existing services as poor, but with a large majority of those in Beaver County considering their services as good or excellent.
With regard to the professional's perception of adequacy of existing services, it was found that the majority of the medical doctors perceived the services as adequate, but the doctors of dental surgery generally perceived the adequacy of service as somewhat less than desirable.
With regard to the last measure, that of adequacy of existing services as determined by a comparison to an established standard, the services in the study area were found to be inadequate in all respects with the single exception of number of hospital beds per 1,000 population in Beaver County.
It was concluded that there is a large degree of consensus between the perceived inadequacy of the health services of the general population in Piute and Wayne counties and the inadequacy demonstrated by the comparison of existing services to an established standard. In Beaver County the reverse is true with the perception of the general population and that of the physician population being very similar, both considering the services adequate but both being in disagreement with adequacy as measured by an established standard.
The findings suggest that more detailed research in the area is needed if a standard of adequacy acceptable to everyone is to be developed.
A Strip Search for New Very Wide Halo Binaries

description: We report on a search for new wide halo binary stars in SDSS Stripe 82. A list of new halo wide binary candidates which satisfy common proper motion and photometric constraints is provided. The projected separations of the sample lie between 0.007-0.25pc. Although the sample is not large enough to improve constraints on dark matter in the halo, we find the wide binary angular separation function is broadly consistent with past work. We discuss the significance of the new sample for a number of astrophysical applications, including as a testbed for ideas about wide binary formation. For the subset of candidates which have radial velocity information we make use of integrals of motion to investigate one such scheme in which the origin of Galactic wide binaries is associated with the accretion/disruption of stellar systems in the Galaxy. Additional spectroscopic observations of these candidate binaries will strengthen their usefulness in many of these respects. Based on our search experience in Stripe 82 we estimate that the upcoming Pan-STARRS survey will increase the sample size of wide halo binaries by over an order of magnitude.
