description: We investigate quantum correlations in microwave radiation produced by the dynamical Casimir effect in a superconducting waveguide terminated and modulated by a superconducting quantum interference device. We apply nonclassicality tests and evaluate the entanglement for the predicted field states. For realistic circuit parameters, including thermal background noise, the results indicate that the produced radiation can be strictly nonclassical and can have a measurable amount of intermode entanglement. If measured experimentally, these nonclassicalilty indicators could give further evidence of the quantum nature of the dynamical Casimir radiation in these circuits.

Year: 2004

description: This investigation is focused on the evaluation of stress corrosion cracking (SCC) and localized corrosion behavior of Type 422 stainless steel in aqueous environments at ambient and elevated temperature. The results of constant load SCC testing using smooth specimens showed no failure in the neutral solution but a threshold stress of 97 ksi was observed in the 90°C acidic environment. SCC testing by the slow-strain-rate test method indicate that the time-to-failure, true failure stress and ductility parameters were gradually reduced with increasing temperature, showing more pronounced effect in the acidic solution. The application of a controlled cathodic potential showed further reduction in the magnitude of these parameters indicating a detrimental effect on the cracking due to hydrogen generation. The results of cyclic potentiodynamic polarization testing revealed pits and crevices on the specimen surface, showing more active (negative) critical pitting potential in the 90°C acidic solution, as expected. Metallographic and fractographic evaluations showed secondary cracks at the gage section and a combination of ductile/brittle failures at the primary fracture face, respectively.

description: A new modeling way of describing the continuous absorption of electromagnetic (EM) radiation in dense partially ionized hydrogen plasma is tested in this work. It is shown that the obtained results give a possibility of calculating spectral absorption coefficients which characterize the relevant absorption processes in partially ionized hydrogen plasmas with electron densities $N_{e} \sim 10^{19}cm^{-3}$ and temperatures $T \approx 2\cdot 10^{4}K$. A key parameter of the used procedure is determined empirically. The calculation method is applied to wavelength region $300nm < λ< 500nm$. The presented results can be of interest for dense laboratory plasmas as well as for partially ionized layers of different stellar atmospheres.

description: We have studied the dependence of the AGN nuclear radio (1.4 GHz) luminosity on both the AGN 2-10 keV X-ray and the host-galaxy K-band luminosity. A complete sample of 1268 X-ray selected AGN (both type 1 and type 2) has been used, which is the largest catalogue of AGN belonging to statistically well defined samples where radio, X and K band information exists. At variance with previous studies, radio upper limits have been statistically taken into account using a Bayesian Maximum Likelihood fitting method. It resulted that a good fit is obtained assuming a plane in the 3D L_R-L_X-L_K space, namely logL_R= xi_X logL_X + xi_K logL_K + xi_0, having a ~1 dex wide (1 sigma) spread in radio luminosity. As already shown, no evidence of bimodality in the radio luminosity distribution was found and therefore any definition of radio loudness in AGN is arbitrary. Using scaling relations between the BH mass and the host galaxy K-band luminosity, we have also derived a new estimate of the BH fundamental plane (in the L_5GHz -L_X-M_BH space). Our analysis shows that previous measures of the BH fundamental plane are biased by ~0.8 dex in favor of the most luminous radio sources. Therefore, many AGN studies, where the BH fundamental plane is used to investigate how AGN regulate their radiative and mechanical luminosity as a function of the accretion rate, or many AGN/galaxy co-evolution models, where radio-feedback is computed using the AGN fundamental plane, should revise their conclusions.

Air quality--Health aspects

description: The Air Indicator Report for Public Awareness and Community Tracking (AIRPACT) is a comprehensive, air quality forecast system that provides air quality forecasting over the Pacific Northwest region, which has been operated by Washington State University since 2001. It consists of the Sparse Matrix Operator Kernel Emissions (SMOKE) model to provide temporal and spatial emissions, the Community Multiscale Air Quality (CMAQ) model to simulate ozone, particulate matter and related precursor and product concentrations, and the Weather Research and Forecasting (WRF) model to simulate meteorology, which are an input to SMOKE and CMAQ. In the first portion of this thesis, we have evaluated AIRPACT forecasts for the last ten years (2009 -2018) against the quality-controlled EPA Air Quality System (AQS) observations, examining how overall air quality forecast skills have changed. AIRPACT has been updated extensively over this time period. Our evaluation results show that AIRPACT predicts significant trends of observations successfully and the forecast skill has generally improved. For all versions, DM8A ozone and Hourly PM2.5 meet benchmark goals. The second section of this thesis involves a comparison between AIRPACT forecasts over the Spokane area with two different horizontal grid sizes: 4km by 4km vs. 1.33km by 1.33km. Though a finer grid could resolve fine-scale processes better than a coarse grid, there is no clear difference in forecasts between the two cases. The last section of this thesis is an analysis of the impact of air quality on public health in the Pacific Northwest (PNW). The Environmental Benefits Mapping and Analysis Program - Community Edition (BenMAP-CE) is used to estimate the impacts on mortality, asthma exacerbation, emergency room visits, and lost work/school days from surface PM2.5 and ozone levels in the PNW during 2016-2018. Three different data sources are used in this analysis: the AIRPACT forecasts (4km by 4km), AQS observations, and a combined AIRPACT and AQS dataset. PM2.5 has a greater mortality and asthma exacerbation health impact than ozone in the PNW, but ozone has higher rates of Emergency Room Visits. PM2.5 induced health impacts like mortality, have a 64% to 80% higher incidence than the opposing ozone related incidence.

description: We study the entanglement entropy of a region of length 2L with the remainder of an infinite one dimensional gapless quantum system in the case where the region is centered on a quantum impurity. The coupling to this impurity is not scale invariant, and the physics involves a crossover between weak and strong coupling regimes. While the impurity contribution to the entanglement has been computed numerically in the past, little is known analytically about it, since in particular the methods of conformal invariance cannot be applied because of the presence of a crossover length. We show in this paper that the small coupling expansion of the entanglement entropy in this problem is quite generally plagued by strong infrared divergences, implying a non-perturbative dependence on the coupling. The large coupling expansion turns out to be better behaved, thanks to powerful results from the boundary CFT formulation and, in some cases, the underlying integrability of the problem. However, it is clear that this expansion does not capture well the crossover physics. In the integrable case -- which includes problems such as an XXZ chain with a modified link, the interacting resonant level model or the anisotropic Kondo model -- a non perturbative approach is in principle possible using form-factors. We adapt in this paper the ideas of [1,2] to the gapless case and show that, in the rather simple case of the resonant level model, and after some additional renormalizations, the form factors approach yields remarkably accurate results for the entanglement all the way from short to large distances. This is confirmed by detailed comparison with numerical simulations. Both our form factor and numerical results are compatible with a non-perturbative form at short distance.

The observed magnetic characteristics as a function of temperature, magnetic field and time, provide evidence for weakly coupled grains through Josephson interaction, revealing the existence of superconducting vortices.

description: In this paper we determine the radius of convexity for three kind of normalized Bessel functions of the first kind. In the mentioned cases the normalized Bessel functions are starlike-univalent and convex-univalent, respectively, on the determined disks. The key tools in the proofs of the main results are some new Mittag-Leffler expansions for quotients of Bessel functions of the first kind, special properties of the zeros of Bessel functions of the first kind and their derivative, and the fact that the smallest positive zeros of some Dini functions are less than the first positive zero of the Bessel function of the first kind. Moreover, we find the optimal parameters for which these normalized Bessel functions are convex in the open unit disk. In addition, we disprove a conjecture of Baricz and Ponnusamy concerning the convexity of the Bessel function of the first kind.

description: This mini review provides an overview of the issues and challenges inherent in autosomal recessive polycystic kidney disease (ARPKD), with a particular focus on the neurological factors and neurocognitive functioning of this population. ARPKD typically is discovered at the end of pregnancy or during the neonatal developmental period and occurs in approximately 1 in 20,000 live births. During the neonatal period, there is a relatively high risk of death, with many infants dying from respiratory failure. As the child ages, they experience progressive kidney disease and become increasingly vulnerable to liver disease, with many individuals eventually requiring dual organ transplants. This mini review provides a brief description of ARPKD and describes the various factors that place children with ARPKD at risk for neurological and neuropsychological impairment (e.g., a genetic condition leading to chronic kidney disease and eventual transplant; difficult-to-treat hypertension; eventual liver disease; possible dual transplantation of the kidneys and liver; chronic lung disease), including that these factors are present during a critical period of brain development. Further, the mini review discusses the available studies that have addressed the neurocognitive functioning in children with ARPKD. This paper concludes by providing the key clinical and research challenges that face the field of pediatric nephrology with respect to the clinical and scientific study of the neurocognitive functioning of children with ARPKD. Selected directions are offered in both the clinical and research arenas for this multiorgan chronic condition.

This yields a novel antichain-based memory structure and a natural notion of permissive strategies for Muller games. Moreover, we generalize our construction by presenting a new type of game reduction from infinite games to safety games and show its applicability to several other winning conditions.

description: AbstractIn response to the International Association of Gerontology and Geriatrics' global agenda for clinical research and quality of care in long-term care homes (LTCHs), the International Consortium on Professional Nursing Practice in Long Term Care Homes (the Consortium) was formed to develop nursing leadership capacity and address the concerns regarding the current state of professional nursing practice in LTCHs. At its invitational, 2-day inaugural meeting, the Consortium brought together international nurse experts to explore the potential of registered nurses (RNs) who work as supervisors or charge nurses within the LTCHs and the value of their contribution in nursing homes, consider what RN competencies might be needed, discuss effective educational (curriculum and practice) experiences, health care policy, and human resources planning requirements, and to identify what sustainable nurse leadership strategies and models might enhance the effectiveness of RNs in improving resident, family, and staff outcomes. The Consortium made recommendations about the following priority issues for action: (1) define the competencies of RNs required to care for older adults in LTCHs; (2) create an LTCH environment in which the RN role is differentiated from other team members and RNs can practice to their full scope; and (3) prepare RN leaders to operate effectively in person-centered care LTCH environments. In addition to clear recommendations for practice, the Consortium identified several areas in which further research is needed. The Consortium advocated for a research agenda that emphasizes an international coordination of research efforts to explore similar issues, the pursuit of examining the impact of nursing and organizational models, and the showcasing of excellence in nursing practice in care homes, so that others might learn from what works. Several studies already under way are also described.

description: After a cerebral stroke, a series of changes at the supraspinal and spinal nervous system can alter the control of muscle activation, leading to persistent motor impairment. However, the relative contribution of these different levels of the nervous system to impaired muscle activation is not well understood. The coherence of motor unit (MU) spike trains is considered to partly reflect activities of higher level control, with different frequency band representing different levels of control. Accordingly, the objective of this study was to quantify the different sources of contribution to altered muscle activation. We examined the coherence of MU spike trains decomposed from surface electromyogram (sEMG) of the first dorsal interosseous muscle on both paretic and contralateral sides of 14 hemispheric stroke survivors. sEMG was obtained over a range of force contraction levels at 40, 50, and 60% of maximum voluntary contraction. Our results showed that MU coherence increased significantly in delta (1–4 Hz), alpha (8–12 Hz), and beta (15–30 Hz) bands on the affected side compared with the contralateral side, but was maintained at the same level in the gamma (30–60 Hz) band. In addition, no significant alteration was observed across medium–high force levels (40–60%). These results indicated that the common synaptic input to motor neurons increased on the paretic side, and the increased common input can originate from changes at multiple levels, including spinal and supraspinal levels following a stroke. All these changes can contribute to impaired activation of affected muscles in stroke survivors. Our findings also provide evidence regarding the different origins of impaired muscle activation poststroke.

description: We provide a construction of sets of (d/2+1) mutually unbiased bases (MUBs) in dimensions d=4,8 using maximal commuting classes of Pauli operators. We show that these incomplete sets cannot be extended further using the operators of the Pauli group. However, specific examples of sets of MUBs obtained using our construction are shown to be strongly unextendible; that is, there does not exist another vector that is unbiased with respect to the elements in the set. We conjecture the existence of such unextendible sets in higher dimensions (d=2^{n}, n>3) as well. Furthermore, we note an interesting connection between these unextendible sets and state-independent proofs of the Kochen-Specker Theorem for two-qubit systems. Our construction also leads to a proof of the tightness of a H_{2} entropic uncertainty relation for any set of three MUBs constructed from Pauli classes in d=4.

description: Temporally-resolved electron density measurements of solar flare plasmas are presented using data from the EUV Variability Experiment (EVE) onboard the Solar Dynamics Observatory (SDO). The EVE spectral range contains emission lines formed between 10^4-10^7 K, including transitions from highly ionized iron (>10 MK). Using three density-sensitive Fe XXI ratios, peak electron densities of 10^(11.2)-10^(12.1) cm^(-3) were found during four X-class flares. While previous measurements of densities at such high temperatures were made at only one point during a flaring event, EVE now allows the temporal evolution of these high-temperature densities to be determined at 10 s cadence. A comparison with GOES data revealed that the peak of the density time profiles for each line ratio correlated well with that of the emission measure time profile for each of the events studied.

description: The method of simplest equation is applied for analysis of a class of lattices described by differential-difference equations that admit traveling-wave solutions constructed on the basis of the solution of the Riccati equation. We denote such lattices as Riccati lattices. We search for Riccati lattices within two classes of lattices: generalized Lotka - Volterra lattices and generalized Holling lattices. We show that from the class of generalized Lotka - Volterra lattices only the Wadati lattice belongs to the class of Riccati lattices. Opposite to this many lattices from the Holling class are Riccati lattices. We construct exact traveling wave solutions on the basis of the solution of Riccati equation for three members of the class of generalized Holing lattices.

Hot subdwarf stars in close-up view - III. Metal abundances of subdwarf B stars

Publisher: name: arXiv
Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Context: Hot subdwarf B stars (sdBs) are considered to be core helium-burning stars with very thin hydrogen envelopes situated on or near the extreme horizontal branch (EHB). The formation of sdBs is still unclear as well as the chemical composition of their atmospheres. The observed helium depletion is attributed to atmospheric diffusion. Metal abundances have been determined for about a dozen sdBs only resulting in puzzling patterns with enrichment of heavy metals and depletion of lighter ones. Aims: In this paper we present a detailed metal abundance analysis of 106 sdBs. Methods: From high resolution spectra we measured elemental abundances of up to 24 different ions per star. A semi-automatic analysis pipeline was developed to calculate and fit LTE models to a standard set of spectral lines. Results: A general trend of enrichment was found with increasing temperature for most of the heavier elements. The lighter elements like carbon, oxygen and nitrogen are depleted and less affected by temperature. Although there is considerable scatter from star to star, the general abundance patterns in most sdBs are similar. State-of-the-art diffusion models predict such patterns and are in qualitative agreement with our results. However, the highest enrichments measured cannot not be explained with these models. Peculiar line shapes of the strongest metal lines in some stars indicate vertical stratification to be present in the atmospheres. Such effects are not accounted for in current diffusion models and may be responsible for some of the yet unexplained abundance anomalies.

Structural analysis of the Hurricane fault in the transition zone between the basin and range province and the Colorado Plateau, Washington County, Utah
Creators: name: Schramm, Meg E.
Publisher: name: University of Nevada, Las Vegas
Year: 1994

description: This study defines fault segments and segment boundaries along the Hurricane fault in southwestern Utah and determines the geometric and kinematic relationship to other regional structures. Fault segment identification is critical for understanding fault processes and seismic risk; segment length is the maximum earthquake rupture length along a fault. Segment boundaries may act as barriers to earthquake propagation.
Normal fault segmentation only recently has received attention and has never been studied along the Hurricane fault. The fault changes strike along its length, and is thus a segmented fault. This study documents one nonconservative segment boundary and two fault segments, the Ash Creek segment and the Anderson Junction segment, based on fault geometry, scarp shape, and shortening structures in the hanging wall and footwall. A rupture along the Ash Creek segment may affect Cedar City, UT, and a rupture along the Anderson Junction segment may affect St. George, UT and a number of smaller nearby towns. Previously undocumented surface offsets were observed along both segments. Evidence that Quaternary slip along the Hurricane fault is predominately normal includes offset of geochemically identical Quaternary (?) basalt, slickenlines, hanging wall dip analysis, and the 89o rake of the 1992 St. George earthquake.
The Hurricane fault and the Gunlock-Grand Wash fault system, which lies 50 km to the west, may be a linked system whereby the two en echelon faults form a displacement transfer zone that generates the relatively wide transition zone between the Basin and Range province and the Colorado Plateau in the region. Data from both faults that support the existence of a transfer zone include symmetric changes in stratigraphic separation, similar timing of fault motion, and balanced regional cross sections.

description: Separate addressing of individual qubits is a challenging requirement for scalable quantum computation, and crosstalk between operations on neighboring qubits remains as a significant source of noise for current experimental implementation of multi-qubit platforms. We propose a scheme based on spatial refocusing from interference of several coherent laser beams to significantly reduce the crosstalk noise for any type of quantum gates. A general framework is developed for the spatial refocusing technique, in particular with practical Gaussian beams, and we show under typical experimental conditions, the crosstalk-induced infidelity of quantum gates can be reduced by several orders of magnitude with a moderate cost of a few correction laser beams.

description: We introduce a new 2-D hexagon technique to probe the topological structure of the universe, in which we map regions of the sky with high and low galaxy densities onto a 2-D lattice of hexagon unit cells, We define filled cells as corresponding to high density regions and empty cells as corresponding to low density region. The number of filled cells and empty cells are kept same by controlling the size of the cells. By analyzing the six neighbors of each hexagon we can get and compare statistical topological properties of the high density and low density regions in the universe, in order to have a better understanding of the evolution of the universe. We apply this hexagon method on 2MASS data and discover significant topological differences between the high density and low density regions. Both regions have significant (>5 Sigma) topological shifts from the binomial distribution or the random distribution.
Buffering PV Output During Cloud Transients with Energy Storage

description: Consideration of the use of the major types of energy storage is attempted in this thesis in order to mitigate the effects of power output transients associated with grid-tied CPV systems due to fast-moving cloud coverage. The approach presented here is to buffer intermittency of CPV output power with an energy storage device (used batteries) purchased cheaply from EV owners or battery leasers. When the CPV is connected to the grid with the proper energy storage, the main goal is to smooth out the intermittent solar power and fluctuant load of the grid with a convenient control strategy. This thesis provides a detailed analysis with appropriate Matlab codes to put onto the grid during the day time a constant amount of power on one hand and on the other, shift the less valuable off-peak electricity to the on-peak time, i.e. between 1pm to 7pm, where the electricity price is much better. In this study, a range of base constant power levels were assumed including 15kW, 20kW, 21kW, 22kW, 23kW, 24kW and 25kW. The hypothesis based on an iterative solution was that the capacity of the battery was increased by steps of 5 while the base supply was decreased by the same step size until satisfactorily results were achieved. Hence, it turned out with the chosen battery capacity of 54kWh coupled to the data from the Amonix CPV 7700 unit for Las Vegas for a 3-month period, it was found that 20kW was the largest constant load the system can supply uninterruptedly to the utility company. Simulated results are presented to show the feasibility of the proposed scheme.

description: Automated decision systems are increasingly used for consequential decision making---for a variety of reasons. These systems often rely on sophisticated yet opaque models, which do not (or hardly) allow for understanding how or why a given decision was arrived at. This is not only problematic from a legal perspective, but non-transparent systems are also prone to yield undesirable (e.g., unfair) outcomes because their sanity is difficult to assess and calibrate in the first place. In this work, we conduct a study to evaluate different attempts of explaining such systems with respect to their effect on people's perceptions of fairness and trustworthiness towards the underlying mechanisms. A pilot study revealed surprising qualitative insights as well as preliminary significant effects, which will have to be verified, extended and thoroughly discussed in the larger main study.

Investigating three decades of vegetation change in a Mojave Desert mountain range
Creators: name: Roberts, Chris Lee
Publisher: name: University of Nevada, Las Vegas
Year: 2012

description: This project is a vegetation change study spanning 29 years in the Newberry Mountains of Southern Nevada. Long term monitoring data are crucial for understanding the effects of climate change on vegetation dynamics. Successful management intervention in vegetation change will require identification of early indicator plant species and their responses to climatic cues. This project is one of the oldest comparisons of resurveyed Mojave vegetation community plots with repeatable methodology and the longest survey interval reported for the southeastern Mojave Desert. 103 plots were relocated and resurveyed based on data methods in Jim Holland's thesis titled "A Vegetative Analysis of the Newberry Mountains, Nevada." We compared measures of species abundance and measures of community composition between the survey years of 1979 and 2008 and further investigated if changes were related to numerous environmental gradients present in the mountain range. Community composition, as measured by relative cover, was the only abundance measure found significantly different between survey years (A= -0.0031, p=0.04). Mountain soils derived from granitic residuum and colluvium showed significantly higher community composition change compared to the alluvial soil of bajadas. Certain plant species, such as Coleogyne ramosissima, associated with specific soils and higher elevations report significant decreases across multiple abundance measures. Other species such as Ferocactus cylindraceus were found to have increased significantly across abundance measures. We address inferred scenarios for changes to species across environmental gradients as well as the suitability of each species and various abundance measures as early indicators of vegetation community change. Overall we found negligible change for most plant species and vegetation communities as represented by multiple abundance measures between survey years. In addition, the analysis provided useful information on the natural history and current status of species within this unique mountain range. Future resurvey efforts with permanently established plots and shorter intervals have exciting potential for more predictive information relating to vegetation change.

The effect of age on relational encoding as revealed by hippocampal functional connectivity

description: The neural processes mediating cognition occur in networks distributed throughout the brain. The encoding and retrieval of relational memories, memories for multiple items or multifeatural events, is supported by a network of brain regions, particularly the hippocampus. The hippocampal coupling hypothesis suggests that the hippocampus is functionally connected with the default mode network (DMN) during retrieval, but during encoding, decouples from the DMN. Based on prior research suggesting that older adults are less able to modulate between brain network states, we tested the hypothesis that older adults’ hippocampus would show functional connectivity with the DMN during relational encoding. The results suggest that, while the hippocampus is functionally connected to some regions of the DMN during relational encoding in both younger and older adults, older adults show additional DMN connectivity. Such age-related changes in network modulation appear not to be mediated by compensatory processes, but rather to reflect a form of neural inefficiency, most likely due to reduced inhibition.

description: We continue the investigation of finite-duration variants of infinite-duration games by extending known results for games played on finite graphs to those played on infinite ones. In particular, we establish an equivalence between pushdown parity games and a finite-duration variant. This allows us to determine the winner of a pushdown parity game by solving a reachability game on a finite tree.

title: Characterization of coarse sediment transport on a mixed sand and gravel beach: Cherry Point Aquatic Reserve, Blaine, Washington
Creators: name: Weaver, Meghan Elizabeth
Publisher: name: Western Washington University
Year: 2013

description:
This study examines coarse-sediment transport behavior on a mixed sand and gravel (MSG) beach at Cherry Point Aquatic Reserve in Blaine, Washington. Radio Frequency Identifier (RFId) Passive Integrated Transponder (PIT) tags were used to trace large pebbles and cobbles (51 - 129 mm in diameter) between mid-January and early-March, 2012. Transport data were combined with wind, current and water level data recorded by nearby weather stations, as well as wave data collected by an offshore pressure sensor, into a comprehensive data set. Tide, wind and wave parameters were then input into XBeach, a relatively new nearshore numerical model [Roelvink et al. 2009], to investigate the critical relationships between oceanic and atmospheric factors and the behavior of coarse sediment at the Reserve. Measured displacement of pebbles and cobbles recorded longshore transport in both directions, with little cross-shore movement. This bi-directional transport supports observations made by Bauer [1976] and adds a new facet of beach behavior to the currently favored, uni-directional net-drift cell model [Schwartz et al. 1991, Johannessen & Chase 2006]. During moderate energy wave activity, the duration of elevated wind speeds above 4 m/s controls the extent of tracer displacement. During high energy winter storms, fetch distance and significant wave height control displacement. Another important discovery is the immobility of the lower beach compared to the middle and upper beach. Computer modeling of wave forcing, roller energy and bed shear stress identifies a critical water level needed to bring roller waves close enough to break over the beach profile and affect coarse-sediment transport.
