title: CIA or CEO: Who Will be Responsible for Helping Protect National Security?
Creators: name: Crandal, Jamie Elizabeth
Publisher: name: Utah State University
Year: 2017

description: As technology advances businesses are being called upon to take an active role in helping protect national security. A variety of different companies and industries within the private sector, which are at the forefront of encryption and hacking technologies, have the option to aid or subvert the intelligence community by sharing breakthrough technology in the interest of helping ensure domestic tranquility.
Many industries and companies within the private sector argue that while they are not actively trying to subvert efforts to protect national security it is not in their best interest, or the best interest of their customers, to hand over proprietary technology to the intelligence community through government enforcement of a court order. As a result of the intelligence community's need for assistance from the private sector and the private sectors refusal to provide aid, both parties have turned to the courts for adjudication of the issue.
The ensuing legal battle over this question of who is responsible for protecting national security will forever change the relationship between the private sector and intelligence. Has the nature of national security been fundamentally changed as the result of technology and our information society? More specifically, is the intelligence community and other governmental agencies solely responsible for protecting national security? Or, in an age of globalization, has national security become the burden of both public and private actors?
The answers to these questions are complex and at the same time straightforward. What was discovered was that while the burden of national security falls to both the public and private sector to an extent. However, it is not the responsibility of the private sector to help protect national security by virtue of providing the intelligence community with proprietary technology or information that could compromise the integrity of a given companies business. Furthermore, the fight to protect national security is important, living in a country that provides certain safety assurances helps businesses grow; but when providing that safety prevents people from living their lives or businesses from operating at their full potential the enemy that the intelligence community is trying to protect us from has already won.
In developing the answers to these questions, this paper takes a broad view of the players involved as well as both sides of the legal battle that has already begun. will end with a discussion of the options and opportunities that will be available to both parties as the battle over who should be responsible for helping protect our national security moves forward in the courts.

Publisher: name: Utah State University
Year: 1970

description: A series of Basic Assembler Language subroutines were developed and made available to the FORTRAN IV language processor which makes list processing possible in a flexible and easily understood way.
The subroutine will create and maintain list structures in the computer's core storage. The subroutines are sufficiently general to permit FORTRAN programmers to tailor list processing routines to their own individual requirements. List structure sizes are limited only by the amount of core storage available. (61 pages)

description: Thermal conductance of graphene nanoribbons (GNRs) with the width varying from 0.5 to 35 nm is systematically investigated using nonequilibrium Green's function method. Anisotropic thermal conductance is observed with the room temperature thermal conductance of zigzag GNRs up to ~ 30% larger than that of armchair GNRs. At room temperature, the anisotropy is found to disappear until the width is larger than 100 nm. This intrinsic anisotropy originate from different boundary condition at ribbon edges, and can be used to tune thermal conductance, which have important implications for the applications of GNRs in nanoelectronics and thermoelectricity.

description: Carers of people with aphasia face unique challenges. Research has demonstrated that these carers have a higher burden of care and more negative stroke-related outcomes in comparison to carers of stroke survivors without aphasia. The aim of this scoping review was to map the range of interventions for carers other than communication partner training and to examine their outcomes. We conducted a scoping review on this topic. Twenty studies were included. Most studies were case series with four randomised control trials. Both quantitative and qualitative approaches were used. Most studies occurred during the long-term phase of care. Two interventions had only carers as participants. Interventions were comprised of different combinations of intervention components including psychoeducation, skill-building, and support. There was high variability on who led the interventions, the format, and the dose/schedule. Twenty-eight different outcome measures for carers and dyads were used across various domains with overall positive outcomes post-intervention. This review uncovered a wide range of formats, dosages, and outcome measures in interventions for carers. Encouragingly, the majority of these interventions included psychoeducation, skill-building, and support components. While most studies were case series, there are promising interventions that have the potential to enhance carer wellbeing. Carer targeted interventions play an important role in reducing carer burden and increasing psychological wellbeing for carers of people with aphasia post-stroke.A tailored intervention for carers of people with aphasia should include components of psychoeducation, skill-building, and support to meet their needs across the continuum of care.Recognising carers as clients has the potential to improve healthcare outcomes for the carer and the person with aphasia.

description: We characterize the convex-cyclic weighted composition operators $W_{(u,ψ)}$ and their adjoints on the Fock space in terms of the derivative powers of $ ψ$ and the location of the eigenvalues of the operators on the complex plane. Such a description is also equivalent to identifying the operators or their adjoints for which their invariant closed convex sets are all invariant subspaces. We further show that the space supports no supercyclic weighted composition operators with respect to the pointwise convergence topology and hence with the weak and strong topologies and answers a question raised by T. Carrol and C. Gilmore in \cite{CC}.
title: Model for Bathtub-Shaped Hazard Rate: Monte Carlo Study
Creators: name: Leithead, Glen S.
Publisher: name: Utah State University
Year: 1970

description: A new model developed for the entire bathtub-shaped hazard rate curve has been evaluated as to its usefulness as a method of reliability estimation. The model is of the form:
F(t) = 1 - exp - (ϴ1tL + ϴ2t + ϴ3tM)
where "L" and "M" were assumed known.
The estimate of reliability obtained from the new model was compared with the traditional restricted sample estimate for four different time intervals and was found to have less bias and variance for all time points.
The was a monte carlo study and the data generated showed that the new model has much potential as a method for estimating reliability. (51 pages)

description: As is well-known, a conformal class of a surface $M$ with boundary $Γ$ is determined by its DN map $Λ$. In the paper, the algorithm for determination of the $b$-period matrix $\mathbb{B}$ of the (Schottky) double of surface with boundary via $Λ$ is presented. Due to the Torelli theorem, $\mathbb{B}$ contains all information on the conformal class of $M$ except the proper way of attaching $Γ$ to it.

description: The passage from orality to writing is a turning point in the culture and its forms, the use of the word, in communication, but also in the same thought. It develops thinking interpretive, reflective, tend to be more general and abstract. But the writing becomes, immediately, the heir of orality, and changes its sign. It fixes it. it submits to the interpretation and variation / specialization, and it gradually becomes clearer and more precisely through the instrument-write. The author studied these topics in educational and he reflects on some aspects of writing as a learning tool.

description: Data-driven methods for remaining useful life (RUL) prediction normally learn features from a fixed window size of a priori of degradation, which may lead to less accurate prediction results on different datasets because of the variance of local features. This paper proposes a method for RUL prediction which depends on a trend feature representing the overall time sequence of degradation. Complete ensemble empirical mode decomposition, followed by a reconstruction procedure, is created to build the trend features. The probability distribution of sensors' measurement learned by conditional neural processes is used to evaluate the trend features. With the best trend feature, a data-driven model using long short-term memory is developed to predict the RUL. To prove the effectiveness of the proposed method, experiments on a benchmark C-MAPSS dataset are carried out and compared with other state-of-the-art methods. Comparison results show that the proposed method achieves the smallest root mean square values in prediction of all RUL.
title: A Report on the Statistical Properties of the Coefficient of Variation and Some Applications
Creators: name: Irvin, Howard P.
Publisher: name: Utah State University
Year: 1970

description: Examples from four disciplines were used to introduce the coefficient of variation which was considered to have considerable usage and application in solving Quality Control and Reliability problems.
The statistical properties were found in the statistical literature and are presented, namely, the mean and the variance of the coefficient of variation. The cumulative probability function was determined by two approximate methods and by using the noncentral t distribution. A graphical method to determine approximate confidence intervals and a method to determine if the coefficients of variation from two samples were significantly different from each other are also provided (with examples).
Applications of the coefficient of variation to solving some of the main problems encountered in industry that are included in this report are: (a) using the coefficient of variation to measure relative efficiency, (b) acceptance sampling, (c) stress versus strength reliability problem, and (d) estimating the shape parameter of the two parameter Weibull.

description: We analyze the spatiotemporal solitary waves of a graded-index multimode optical fiber with a parabolic transverse index profile. Using the nonpolynomial Schrödinger equation approach, we derive an effective one-dimensional Lagrangian associated with the Laguerre-Gauss modes with a generic radial mode number p and azimuthal index m. We show that the form of the equations of motion for any Laguerre-Gauss mode is particularly simple, and we derive the critical power for the collapse for every mode. By solving the nonpolynomial Schrödinger equation, we provide a comparison of the stationary mode profiles in the radial and temporal coordinates.

title: A Survey in Mean Value Theorems
Creators: name: Neuser, David A.
Publisher: name: Utah State University
Year: 1970

description: A variety of new mean value theorems are presented along with interesting proofs and generalizations of the standard theorems.
Three proofs are given for the ordinary Mean Value Theorem for derivatives, the third of which is interesting in that it is independent of of Rolle's Theorem. The Second Mean Value Theorem for derivatives is generalized, with the use of determinants, to three functions and also generalized in terms of nth order derivatives.
Observing that under certain conditions the tangent line to the curve of a differentiable function passes through the initial point, we find a new type of mean value theorem for derivatives. This theorem is extended to two functions and later in the paper an integral analog is given together with integral mean value theorems.
Many new mean value theorems are presented in their respective settings including theorems for the total variation of a function, the arc length of the graph of a function, and for vector-valued functions. A mean value theorem in the complex plane is given in which the difference quotient is equal to a linear combination of the values of the derivative. Using a regular derivative, the ordinary Mean Value Theorem for derivatives is extended into Rn, n>1.

Unsaturated ditertiary arsine derivatives of some metal carbonyls

Publisher: name: University of British Columbia
Year: 2010

description: The meso and racemic forms of the new ditertiary arsine, cis-2,3-bis(methylphenylarsino)-1,1,1,k,khexafluorobut-2-ene (L-L)', were prepared "by the reaction of hexafluorobutyne-2 with 1,2-dimethyl-l,2-diphenyldiarsine in hexafluoroacetone. The two diastereomers were isolated and reacted with iron pentacarbonyl affording (L-L)' Fe(CO)₃ and (L-L) Fe₂(C0)₆. Two of the three possible geometric isomers of the latter were obtained and their properties allowed assignment of the configuration of the starting ligands. Minor amounts of the symmetric and asymmetric forms of Fe₂(CO)₆[As(CH₃)(C₆H₅)]₂ were also obtained through loss of fluorocarbon. The complexes Fe₂(CO)₆[E(R₁)(R₂)]₂ (E = As, P; R₁ = R₂ = CH₃; R₁ = CH₃, R₂ = C₆H₅) were prepared and studied by ¹H and ¹³C nmr spectroscopy. Variable temperature ¹H nmr studies indicate the hexacarbonyl complexes are fluxional with respect to the [Fe-E]₂ cluster. Activation parameters were calculated for the motion and possible mechanisms are discussed. The ¹³C nmr spectra of the carbonyl groups at 25° and -70° suggest an independent intramolecular scrambling of the carbonyl groups about the iron atom. Reactions of (L-L)' and the related ditertiary arsine ligand, cis-2,3-bis(dimethylarsino)-1,1,1,h,b,4-hexafluorobut-2-ene (L-L), with the Group VI metal hexacarbonyls gave the chelate complexes (L-L)' M(CO)₄ and (L-L)M(CO)₄. The (L-L)M-(CO)₄ complexes were irradiated with the 450W lamp in the presence of excess (L-L), giving four different types of complexes: fac-(L-L)[sup b](L-L)[sup m]M(CO)₃ and fac-(L-L)[sup b](L-L)[sup m][sup trans]M(CO)₃ (where b and m denote bidentate and monodentate ligand respectively), cis-(L-L)₂M(CO)₂ and trans-(L-L)₂M(CO)₂. The seven-coordinate complexes (L-L)' M(CO)₃X₂ and (L-L)-M(CO)₃X₂ (M = Mo, W; X = Br, I) were prepared and characterized and ¹H nmr spectra at 25° and -70° suggest the complexes are nonrigid. Similarly ¹H nmr studies indicate the seven-coordinate (L-L)LMo(CO)₂ Br₂ complexes are also nonrigid at 25° and -70°. The (L-L)L₂Mo(CO)Br₂ complexes (L is a monodentate phosphite or phosphine) are rigid at 25° and nonrigid at higher temperatures. Activation parameters were calculated for the motion of two of the complexes. Finally, two novel Group VII metal carbonyl complexes of (L-L) of formula C₁₆H₁₈As₃F₅O₆Mn₂ and C₁₁H₈AsF₆O₅Re are described. The former contains a fluorinated n-allyl group bonded to one manganese atom and the latter a CH₂O fragment σ-bonded to rhenium.

description: For pairs of holomorphic maps $(u,ψ)$ on the complex plane, we study some dynamical properties of the weighted composition operator $W_{(u,ψ)}$ on the Fock spaces. We prove that no weighted composition operator on the Fock spaces is supercyclic. Conditions under which the operators satisfy the Ritt's resolvent growth condition are also identified. In particular, we show that a non-trivial composition operator on the Fock spaces satisfies such a growth condition if and only if it is compact.

description: The latest generation of personal devices available on the market consists of devices in cloud mode, devoid of physicalness, and working exclusively online. We are now witnessing the dawn of the post-PC era, in which the individual, by now open source, is undergoing a constant mutation of self resulting in a shared cloud identity. Within such a new world-system, by now a spatio-temporal cyber-limbo governed by a stream of multi-code information, the subject experiences his or her own becoming. By virtue of such phenomenologies, man, genetically bound to an evolutionary continuum, modifies his own άνθροπος in an unceasing autopoietic process, also thanks to the symbiotic potentials of the new devices. All this in virtue of a hypothetical, eternal optimization of his own status, the source of a different type of man, with a virtually multiple and shared self as well as an unusual trans-identitarian nature, that of the Multimensch, whose aspects are now under study. In the light of such processes, still in progress, an epistemological reflection is worth undertaking. Aimed at identifying the possible vectors of a pedagogical hypothesis taking into account the consequences on a cognitive and social level of such phenomenologies connoting contemporary man, such reflection results in an attempt to find an answer to the proliferation of non-places and non-times in which each individual today expresses his or her being in and of the world. This article is a Research Letter on this on-going research outlook, of which I have presented the basic outline from which the study will be developed.

description: Three Algol-type binary systems (IO Cep, IM Cep and TX Ari) showing cyclic orbital period changes are studied. The combination of time of minimum data from the ground-based observations together with high precision photometric data from the TESS satellite enabled us to estimate the basic light curve elements of binary systems and mass functions for distant components around the systems. The relation of mass ratio to the system geometry in semi-detached binary stars allowed us to determine the mass ratio of the binary components without using spectra. By using the color and distance information from the GAIA EDR3 and light contributions of the components from the light curve analysis, the astrophysical parameters of the binary components as well as the minimum masses of the distant components are obtained with an uncertainty of ~10-20 per cent indicating that the method can be a good guide for those studying with faint systems where spectra with sufficient resolution and S/N ratio are difficult to acquire.

description: Tidally induced spin-up of stripped helium stars in short-period (<\,1\,d) binaries with black holes has been presented as one of the possible mechanisms to reproduce the high-spin tail of the black hole spin distribution derived from gravitational wave (GW) merger observations. At such short periods, a fraction of the strong stellar wind from the stripped helium stars may be accreted by the black holes, and its gravitational potential energy may be released as observable radiation in the X-ray regime. We estimate the X-ray luminosity and its observability from black holes in orbit with stripped helium stars, which evolve into binary black hole or black hole+neutron star binaries that merge within Hubble time. We post-process recent advancements for estimating X-ray luminosities (via wind accretion onto stellar mass black holes) into two rapid population synthesis codes, BSE and StarTrack. We derive lower limits on the X-ray luminosity distribution from populations of stripped helium+black hole binaries at four metallicities (0.01, 0.1, 0.5, 1 $Z_{\odot}$) and two mass transfer stability criteria. We find that a large fraction (0.1-0.5) of stripped-helium stars that get spun up by tides also transfer enough wind matter onto the black hole to produce X-ray luminosities above $10^{35}$\,erg\,s$^{-1}$, up to $\sim10^{39}$\,erg\,s$^{-1}$. Such binaries should be observable as X-ray bright systems at 0.1\,$Z_{\odot}$, 0.5\,$Z_{\odot}$ and $Z_{\odot}$, representative of Sextans A, the Large Magellanic Cloud (LMC) and the Solar neighbourhood, respectively. The formation efficiency of these systems increases with decreasing metallicity. However, accounting for the local star formation rates, our population synthesis predicts $\sim$2 and $\sim$1 such observable binaries in the Milky Way and LMC, respectively, that will produce a binary compact object merger within a Hubble time.

description: We present a theory of spin waves in a non-condensed gas of spin-1 bosons: providing both analytic calculations of the linear theory, and full numerical simulations of the nonlinear response. We highlight the role of spin-dependent contact interactions in the dynamics of a thermal gas. Although these interactions are small compared to the thermal energy, they set the scale for low energy long wavelength spin waves. In particular, we find that the polar state of Rb-87 is unstable to collisional mixing of magnetic sublevels even in the normal state. We augment our analytic calculations by providing full numerical simulations of a trapped gas, explicitly demonstrating this instability. Further we show that for strong enough anti-ferromagnetic interactions, the polar gas is unstable. Finally we explore coherent population dynamics in a collisionless transversely polarized gas.

The $ν= 4/3$ and $5/3$ states, which are absent at zero back-gate voltage, emerge as the quantum well is made more symmetric by applying a positive back-gate voltage. The dependence of zero-field electron mobility on the quantum-well asymmetry reveals a significant contribution of interface-roughness scattering, with much stronger scattering at the lower InAs/AlGaSb interface. However, the dependence of the visibility of the FQH effects on the quantum-well asymmetry is not entirely consistent with that of mobility, suggesting that a different source of disorder is also at work.

description: Upcoming missions to explore planetary bodies in the solar system will require accurate position and velocity data during descent in order to land safely at a predesignated site. A Doppler lidar instrument could provide measurements of the altitude, attitude, and velocity of the landing vehicle to supplement the data collected by other instruments. A flexible simulation tool would aid the tasks of designing and testing the functionality of such an instrument.
LadarSIM is a robust parameterized simulation tool developed for time of flight lidar at Utah State University's Center for Advanced Imaging Ladar. This thesis outlines how LadarSIM was modified to include a simulation of Doppler lidar. A study is performed using LadarSIM to determine the effects of varying certain parameters of a Doppler lidar system. Point clouds of landing scenarios generated by the simulation with different scanning patterns are shown.
title: Estimating Evapotranspiration Using the Complementary Relationship and the Budyko Framework

description: Land surface actual evapotranspiration (ET) is an important process in terrestrial water balance and reliable estimates of ET are necessary to improve water resources management. In this regard, there is a growing body of literature that recognizes the importance of an accurate ET model. Among them, the complementary relationship between ET and potential ET (ETP) has been the subject of many studies because it uses only meteorological data as inputs. However, there is an increasing concern that some complementary relationship models perform poorly under dry conditions. To overcome this limitation, this dissertation was designed to extend the latest complementary relationship model, Modified GG, using both meteorological data and vegetation information, NDVI, which is readily available from remote sensing data. The proposed model, Adjusted GG-NDVI, was validated by comparing to other ET models and measured ET data. With Adjusted GG-NDVI, this dissertation addressed the applicability of using ET as a proxy for drought monitoring. As a result, the drought patterns from the proposed drought index, EWDI, were consistent with commonly used USDM in the United States. More importantly, this study described drought conditions by comprehensively considering both precipitation and vegetation conditions. Taken together, these findings have significant implications for the understanding of how ET can assist in water resources management.

description: Overabundance of shrubs poses a major threat to semiarid ecosystems due to degraded understory vegetation. Previous efforts suggest a need for greater understanding of which management practices work best to improve these ecosystems. I sought to develop a better understanding of how the relative performance of commonly seeded species is influenced by three sagebrush removal techniques.
I calculated effect sizes for cover and frequency to estimate relative changes in abundance of 15 common plant species seeded at 63 restoration sites throughout Utah. Shrubs were reduced by fire or mechanical treatment. Effect sizes were assessed using meta-analysis techniques for two post-treatment timeframes. Introduced grasses and shrubs had greater increases in cover and frequency following treatment, respectively. The introduced shrub Bassia prostrata experienced the largest increases in abundance following treatments. Forb abundance was highest when treated with fire. Over the long term the fire treatment resulted in greater increases for four of the seven grass species. Large increases in perennial grasses over time suggest that seeding efforts contributed to enhancing understory herbaceous conditions. My results provide new insights regarding the interactive effects of species and shrub-reduction treatments.
Secondly, I evaluated emergence patterns of six commonly seeded restoration species in soils collected from Wyoming big sagebrush (A. t. ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) and mountain big sagebrush (A. t. ssp. vaseyana [Rydb.] Beetle) plant communities. I developed a novel experimental design that regularly wetted soils to field capacity and allowed them to naturally dry by evaporation, which resulted in distinct differences in the duration of wet-dry cycles. Results showed that inherent differences in soil texture and organic matter between vaseyana and wyomingensis soils translated into fundamental differences in soil water holding capacity. Although species collectively exhibited greater emergence in vaseyana soils than wyomingensis soil, patterns were vastly different among species and differences between soils became more pronounced under low soil water for two of the test species. I concluded that the manner in which soils and water uniquely influenced emergence patterns provide new insights in species suitability for restoration sites and how inherent soil differences may constrain seeding success.

description: Eight years after the first detection of high-energy astrophysical neutrinos by IceCube we are still almost clueless as regards to their origin, although the case for blazars being neutrino sources is getting stronger. After the first significant association at the $3 - 3.5\,σ$ level in time and space with IceCube neutrinos, i.e. the blazar TXS 0506+056 at $z=0.3365$, some of us have in fact selected a unique sample of 47 blazars, out of which $\sim 16$ could be associated with individual neutrino track events detected by IceCube. Building upon our recent spectroscopy work on these objects, here we characterise them to determine their real nature and check if they are different from the rest of the blazar population. For the first time we also present a systematic study of the frequency of masquerading BL Lacs, i.e. flat-spectrum radio quasars with their broad lines swamped by non-thermal jet emission, in a $γ$-ray- and IceCube-selected sample, finding a fraction $>$ 24 per cent and possibly as high as 80 per cent. In terms of their broad-band properties, our sources appear to be indistinguishable from the rest of the blazar population. We also discuss two theoretical scenarios for neutrino emission, one in which neutrinos are produced in interactions of protons with jet photons and one in which the target photons are from the broad line region. Both scenarios can equally account for the neutrino-blazar correlation observed by some of us. Future observations with neutrino telescopes and X-ray satellites will test them out.

Ageing, gait and falls risk

description: Mobility impairments are extremely common in older age, often resulting in loss of independence, reduced social participation and injuries from falls. As well as reduced quality of life, these outcomes produce significant medical and residential care costs for the individual and for society. With the rapid ageing of populations, there is an urgent need to identify risk factors to prevent mobility decline and associated problems. This thesis aims to examine associations between age and walking performance, their relationships to the sensorimotor factors that may contribute to walking impairments, and finally to identify measures of walking performance that increase the risk of falling. In studies of population-based samples of community dwelling older adults (60-86 years), greater age was associated with poorer performance in gait speed, step length, double support phase and step width among persons of each sex, and additionally with slower cadence among women. Among men the associations were linear. For women, stronger associations were found among those of greater age. Gait variability measures (the fluctuation in a gait measure from one step to the next) were also examined. Apart from step time variability, for which stronger associations were seen for older women, greater variability in gait measures was linearly associated with greater age. In further studies of the same population, poorer performance on a range of sensorimotor factors was associated with impaired gait speed, step length, cadence, double support phase and step width, and with greater gait variability. Quadriceps strength explained the greatest proportion of variance for the majority of average measures of gait, whereas postural sway measured with eyes closed standing on a foam mat explained the greatest proportion of variance for gait variability. Differences in the pattern of associations between the sensorimotor factors and average measures of gait were seen for men and women. Information on falls was collected prospectively over a 12 month period. Greater step length variability and double support phase variability were linearly associated with increased risk of multiple falls, whereas gait speed, cadence and step time variability were non-linearly associated with increased risk of multiple falls. None of the gait measures predicted risk of single falls. In conclusion, this series of related studies add considerably to knowledge about age-related changes in walking, and to understanding of gait measures and sensorimotor factors that may be targeted to prevent walking impairment and loss of independence in older age. Specific gait measures which may be useful in identifying those at risk and used as outcome measures in intervention programs to reduce falls risk, have been identified.

description: The intrinsic structural metastability in cuprate high T$_c$ materials, evidenced in a checker-board domain structure of the CuO$_2$ planes, locally breaks translational and rotational symmetry. Dynamical charge - deformation fluctuations of such nano-size unidirectional domains, involving Cu-O-Cu molecular bonds, result in resonantly fluctuating diamagnetic pairs embedded in a correlated Fermi liquid. As a consequence, the single-particle spectral properties acquire simultaneously (i) fermionic low energy Bogoliubov branches for propagating Cooper pairs and (ii) bosonic localized glassy structures for tightly bound states of them at high energies. The partial localization of the single-particle excitations results in a fractionation of the Fermi surface as the strength of the exchange coupling between itinerant fermions and partially localized fermion pairs increases upon moving from the nodal to the anti-nodal point. This is also the reason why, upon hole doping, bound fermion pairs predominantly accumulate near the anti-nodal points and ultimately condense in an anisotropic fashion, tracking the gap in the single particle spectrum.

description: We have used high-speed spectroscopy of the rapidly oscillating Ap (roAp) star HD99563 to study the pulsation amplitude and phase behaviour of elements in its stratified atmosphere over one 2.91-d rotation cycle. We identify spectral features related to patches in the surface distribution of chemical elements and study the pulsation amplitudes and phases as the patches move across the stellar disk. The variations are consistent with a distorted nonradial dipole pulsation mode. We measure a 1.6 km/s rotational variation in the mean radial velocities of H-alpha and argue that this is the first observation of H-alpha abundance spots caused by He settling through suppression of convection by the magnetic field on an oblique rotator, in support of a prime theory for the excitation mechanism of roAp star pulsation. We demonstrate that HD99563 is the second roAp star to show aspect dependence of blue-to-red running wave line profile variations in Nd iii spots.
