description: A dynamic state estimation method of integrated natural gas and electric power systems (IGESs) in proposed. Firstly, the coupling model of gas pipeline networks and power systems by gas turbine units (GTUs) is established. Secondly, the Kalman filter based linear DSE model for the IGES is built. The gas density and mass flow rate, as well as the real and imaginary parts of bus voltages are taken as states, which are predicted by the linearized fluid dynamic equations of gases and exponential smoothing techniques. Boundary conditions of pipeline networks are used as supplementary constraints in the system model. At last, the proposed method is applied to an IGES including a 30-node pipeline network and IEEE 39-bus system coupled by two GTUs. Two indexes are used to evaluate the DSE performance under three measurement error conditions, and the results show that the DSE can obtain the accurate dynamic states in different conditions.

X-ray absorption in Compton-thin AGN: the predictions of a model revisited

description: The evidence of a decrease with increasing luminosity of the fraction f_{abs} of absorbed and Compton-thin among X-ray (2-10 keV) selected AGN is observationally rather well supported, while that of an increase of f_{abs} with redshift is rather controversial. In Lamastra, Perola & Matt (2006) the gravitational effect of the SMBH on the molecular interstellar gas, in the central region of the host galaxy, was shown to predict an anti-correlation between f_{abs} and M_{BH}. The most recent findings on the distribution of the Eddington ratio λ=L_b/L_E as a function of M_{BH} and z are used to convert that relationship into one between f_{abs} and both bolometric (L_b) and X-ray (L_X) luminosities at various values of z. The findings on λ(M_{BH},z) are properly treated in order to ensure completeness in the prediction of f_{abs} above a certain luminosity, at values of z=0.1, 0.35, 0.7 and >1. To verify the consequence of these findings alone, we adopted in a first istance a distribution of gas surface density Σ, observed in a sample of local spiral galaxies, irrespective of the galaxy morphological type and z. Assuming in the λ(M_{BH},z) distribution the Eddington limit, λ=1, as a ``natural'' cut-off, the predictions are consistent with the existence of an anti-correlation between f_{abs} and L_X, but fail to reproduce an increase of f_{abs} with z. Because the early type galaxies on average are much poorer in molecular gas than late type ones, a quantitative agreement with the local value of f_{abs} requires the existence of a correlation between Σand the central activity. An increase of typical values of Σwith z, correlated with the activity, might explain an increase of f_{abs} with z. However, at the highest luminosities f_{abs} could hardly exceed about 0.3.

description: © 2016 Author(s). The uniform electron gas and the hydrogen atom play fundamental roles in condensed matter physics and quantum chemistry. The former has an infinite number of electrons uniformly distributed over the neutralizing positively charged background, and the latter only one electron bound to the proton. The uniform electron gas was used to derive the local spin density approximation to the exchange-correlation functional that undergirds the development of the Kohn-Sham density functional theory. We show here that the ground-state exchange-correlation energies of the hydrogen atom and many other 1- and 2-electron systems are modeled surprisingly well by a different local spin density approximation (LSDA0). LSDA0 is constructed to satisfy exact constraints but agrees surprisingly well with the exact results for a uniform two-electron density in a finite, curved three-dimensional space. We also apply LSDA0 to excited or noded 1-electron densities, where it works less well. Furthermore, we show that the localization of the exact exchange hole for a 1- or 2-electron ground state can be measured by the ratio of the exact exchange energy to its optimal lower bound.
Long-term tidal evolution of short-period planets with companions

description: Of the fourteen transiting extrasolar planetary systems for which radii have been measured, at least three appear to be considerably larger than theoretical estimates suggest. It has been proposed by Bodenheimer, Lin & Mardling that undetected companions acting to excite the orbital eccentricity are responsible for these oversized planets, as they find new equilibrium radii in response to being tidally heated. In the case of HD 209458, this hypothesis has been rejected by some authors because there is no sign of such a companion at the 5 m/s level, and because it is difficult to say conclusively that the eccentricity is non-zero. Transit timing analysis [...]. Whether or not a companion is responsible for the large radius of HD 209458b, almost certainly some short-period systems have companions which force their eccentricities to nonzero values. This paper is dedicated to quantifying this effect. The eccentricity of a short-period planet will only be excited as long as its (non-resonant) companion's eccentricity is non-zero. Here we show that the latter decays on a timescale which depends on the structure of the interior planet, a timescale which is often shorter than the lifetime of the system. This includes Earth-mass planets in the habitable zones of some stars. We determine which configurations are capable of sustaining significant eccentricity for at least the age of the system, and show that these include systems with companion masses as low as a fraction of an Earth mass. The orbital parameters of such companions are consistent with recent calculations which show that the migration process can induce the formation of low mass planets external to the orbits of hot Jupiters. Systems with inflated planets are therefore good targets in the search for terrestrial planets.

description: Recent years have seen an explosive research and development of nanoplasmonics in the visible and near-infrared (near-ir) frequency regions. One of the most fundamental effects in nanoplasmonics is nano-concentration of optical energy. Plasmonic nanofocusing has been predicted and experimentally achieved. It will be very beneficial for the fundamental science, engineering, environmental, and defense applications to be able to nano-concentrate terahertz radiation (frequency 1 - 10 THz or vacuum wavelength 300 - 30 microns). This will allow for the nanoscale spatial resolution for THz imaging and introduce the THz spectroscopy on the nanoscale, taking full advantage of the rich THz spectra and submicron to nanoscale structures of many engineering, physical, and biological objects of wide interest: electronic components (integrated circuits, etc.), bacteria, their spores, viruses, macromolecules, carbon clusters and nanotubes, etc. In this Letter we establish the principal limits for the nanoconcentration of the THz radiation in metal/dielectric waveguides and determine their optimum shapes required for this nanoconcentration We predict that the adiabatic compression of THz radiation from the initial spot size of light wavelength to the final size of R = 100 - 250 nm can be achieved with the THz radiation intensity increased by a factor of 10 to 250. This THz energy nanoconcentration will not only improve the spatial resolution and increase the signal/noise ratio for the THz imaging and spectroscopy, but in combination with the recently developed sources of powerful THz pulses will allow the observation of nonlinear THz effects and a carrying out a variety of nonlinear spectroscopies (such as two-dimensional spectroscopy), which are highly informative.

description: Approximating model predictive control (MPC) policy using expert-based supervised learning techniques requires labeled training data sets sampled from the MPC policy. This is typically obtained by sampling the feasible state-space and evaluating the control law by solving the numerical optimization problem offline for each sample. Although the resulting approximate policy can be cheaply evaluated online, generating large training samples to learn the MPC policy can be time consuming and prohibitively expensive. This is one of the fundamental bottlenecks that limit the design and implementation of MPC policy approximation. This technical note aims to address this challenge, and proposes a novel sensitivity-based data augmentation scheme for direct policy approximation. The proposed approach is based on exploiting the parametric sensitivities to cheaply generate additional training samples in the neighborhood of the existing samples.

Exchange between deep donors in semiconductors: a quantum defect approach

Year: 2007

description: Exchange interactions among defects in semiconductors are commonly treated within effective-mass theory using a scaled hydrogenic wave-function. However such a wave-function is only applicable to shallow impurities; here we present a simple but robust generalization to treat deep donors, in which we treat the long-range part of the wavefunction using the well established quantum defect theory, and include a model central-cell correction to fix the bound-state eigenvalue at the experimentally observed value. This allows us to compute the effect of binding energy on exchange interactions as a function of donor distance; this is a significant quantity given recent proposals to carry out quantum information processing using deep donors. As expected, exchange interactions are suppressed (or increased), compared to the hydrogenic case, by the greater localization (or delocalization) of the wavefunctions of deep donors (or `super-shallow' donors with binding energy less then the hydrogenic value). The calculated results are compared with a simple scaling of the Heitler-London hydrogenic exchange; the scaled hydrogenic results give the correct order of magnitude but fail to reproduce quantitatively our calculations. We calculate the donor exchange in silicon including inter-valley interference terms for donor pairs along the $\{100\}$ direction, and also show the influence of the donor type on the distribution of nearest-neighbour exchange constants at different concentrations. Our methods can be used to compute the exchange interactions between two donor electrons with arbitrary binding energy.

description: Objective: To analyze patient-reported swallowing difficulties, healthcare resource utilization, and associated costs during PROCLAIM study. Methods: Patients with Stage III nonsquamous non-small cell lung cancer received pemetrexed-cisplatin combined with concurrent thoracic radiotherapy followed by consolidation pemetrexed, or standard concurrent chemoradiotherapy with consolidation. Patient - reported swallowing function was measured using diary. Resource utilization (hospitalizations, transfusions, concomitant medications) was compared between treatment arms using Fisher’s exact test and independent t-test. Medical resource use costs were analyzed using nonparametric Wilcoxon rank sum test. Results: Patient-reported difficulty in swallowing function (diary score ≥4) was 33.8% in PemCis arm and 29% in EtoCis arm. Overall resource use, including hospitalizations, was similar between treatment arms; however, fewer patients in PemCis arm received transfusions and selected concomitant medications. Concurrent phase analyses were consistent with the overall study. Significantly lower percentage of patients (31.1% vs 40.8%) were hospitalized in PemCis arm. Total costs were significantly higher in PemCis arm. Other medical costs (excluding study treatment costs) during the concurrent phase were lower for patients in PemCis arm, due to significantly lower hospitalization costs and lower use of concomitant medications. Subgroup analysis yielded similar results. Conclusions: Patient-reported difficulty in swallowing post-baseline and resource utilization were consistent with previously reported safety outcomes. In the overall study, higher total costs for PemCis were driven by study drug cost. When adjusting for treatment duration, other monthly medical costs were favorable to PemCis. Patients on pemetrexed remained longer on therapy, suggesting better tolerability. ClinicalTrials.gov Identifier: NCT00686959

description:  

Maturity models serve as structured frameworks designed to evaluate and guide the progression of capabilities within an organization or a specific domain 1. These models provide a systematic approach to assess the current state of development, identify existing gaps, and formulate strategic initiatives aimed at achieving desired improvements 1. The utility of maturity models has led to their widespread adoption across diverse fields, encompassing organizational development, information technology, and the rapidly evolving domain of artificial intelligence 1. This broad application underscores the fundamental human desire for structure and a clear path for advancement in complex endeavors. The emergence of the A3 maturity model, developed by Vendan Ananda Kumararajah, presents a new perspective within this established landscape 2 . This report seeks to address a central question regarding its novelty: Is the A3 model the first to address the concepts of ontology, consciousness, and experience in a structured manner? This inquiry is particularly pertinent given the A3 model's apparent emphasis on these philosophical and human-centric concepts, as indicated by preliminary information 2. To provide a comprehensive answer, this report will first deconstruct the A3 maturity model, examining its core principles and its specific approach to ontology, consciousness, and experience. Subsequently, a review of established maturity models, particularly in the realm of AI adoption and organizational development, will be conducted. Following this, a comparative analysis will juxtapose the A3 model's treatment of these concepts with that of other frameworks. Finally, a conclusion will synthesize the findings to address the initial query and discuss the broader implications of the A3 model's unique perspective.

description: Market segmentation is a fundamental business strategy that involves dividing a broad target market, typically composed of a diverse group of potential customers, into smaller, more homogeneous subgroups. These subgroups, or segments, are identified based on shared characteristics such as demographics, psychographics, geographic location, and consumer behaviour. The purpose of market segmentation is to enable companies to deliver more targeted and relevant marketing efforts, ensuring that products, services, and communications resonate with specific audiences. By aligning business strategies with the unique needs of each segment, companies can enhance customer satisfaction, foster brand loyalty, and increase overall profitability.The effectiveness of market segmentation varies across industries, as different sectors benefit from different approaches to segmentation. For instance, in industries such as retail and consumer goods, market segmentation allows for personalized marketing strategies that appeal to distinct consumer tastes and preferences. In contrast, technology and automotive sectors often use segmentation to cater to varying consumer needs, such as functionality, innovation, or price sensitivity. In service-based industries like healthcare, education, and finance, segmentation helps companies tailor offerings to meet the specific demands of different customer groups, including factors like age, income, or lifestyle.This analysis delves into the effectiveness of market segmentation strategies across a variety of industries, examining how these strategies are implemented, the challenges faced, and the measurable outcomes. Through this exploration, we aim to provide a comprehensive understanding of how market segmentation drives business success and why it remains a crucial tool for companies seeking competitive advantage.

description: © 2016 American Physical Society. Liquid argon is a bright scintillator with potent particle identification properties, making it an attractive target for direct-detection dark matter searches. The DarkSide-50 dark matter search here reports the first WIMP search results obtained using a target of low-radioactivity argon. DarkSide-50 is a dark matter detector, using a two-phase liquid argon time projection chamber, located at the Laboratori Nazionali del Gran Sasso. The underground argon is shown to contain Ar39 at a level reduced by a factor (1.4±0.2)×103 relative to atmospheric argon. We report a background-free null result from (2616±43) kg d of data, accumulated over 70.9 live days. When combined with our previous search using an atmospheric argon, the 90% C.L. upper limit on the WIMP-nucleon spin-independent cross section, based on zero events found in the WIMP search regions, is 2.0×10-44 cm2 (8.6×10-44 cm2, 8.0×10-43 cm2) for a WIMP mass of 100 GeV/c2 (1 TeV/c2, 10 TeV/c2).
title: An Analysis of Sound Communication in the Water Vole, Microtus richardsoni (Rodentia: Microtinae)
Creators: name: Tang, Dane R.
Publisher: name: Utah State University
Year: 1975

description: Adult members of the species Microtus richardsoni were used to study the importance of acoustic communication in these voles. Tests were run with single individuals and nonbreeding pairs of voles to obtain recordings and sonagraphs of sounds emitted during exploration of a new cage, agonistic encounters, encounters with a potential predator and in response to miscellaneous aversive stimuli. Of the four groups of tests conducted, sounds were used by M. richardsoni during the last three. The results of this study showed that the water vole emitted ten different call types or sounds. These sounds were separated by similarity into Group I, Group II, tooth-chatter and miscellaneous sound types. Group I calls included the squeal, squawk, grind and complex. These calls were similar in intensity and in having harmonics extending into the ultrasonic range. The squeal consisted of a fundamental frequency plus several distinct, harmonically-related overtones. The squawk resembled the squeal, but the harmonics in the higher frequencies of the former call were obscured by noise. The complex was found to be a combination of two or all three of the other calls. The Group II call types emitted by the water vole were the voiced and voiceless whimpers. These two calls were similar in that each was emitted at low intensity and neither call had harmonics extending into the ultrasonic range. The voiceless whimper was different from the voiced whimper in that its harmonics were obscured by noise. The squawk, grind, complex, voiced whimper and voiceless whimper are inferred to be modifications of the squeal. The primary function of these six call types is postulated to indicate the degree of submissiveness of the vocalizing vole. Modification of the calls is probably related to the motivational state of the animal emitting the call. A secondary effect of the calls might be to inhibit further aggression by the opponent. A seventh sound emitted by the water vole was the tooth-chatter. This sound, also used by many other rodents, was used to communicate threat. The miscellaneous sounds emitted by these voles included the ultrasonic chirp, the peep and the "whooping" call. These calls were not emitted frequently enough to postulate their function. This study showed that sound is used mainly by Microtus richardsoni during agonistic situations and may be adaptive in inhibiting aggression. The use of the physical characteristics of sounds in determining taxonomic relationships is postulated.

description: We analyze the relationship between Borel measures and continuous linear functionals on the space $\mathrm{Lip}_0(M)$ of Lipschitz functions on a complete metric space $M$. In particular, we describe continuous functionals arising from measures and vice versa. In the case of weak$^\ast$ continuous functionals, i.e. members of the Lipschitz-free space $\mathcal{F}(M)$, measures on $M$ are considered. For the general case, we show that the appropriate setting is rather the uniform (or Samuel) compactification of $M$ and that it is consistent with the treatment of $\mathcal{F}(M)$. This setting also allows us to give a definition of support for all elements of $\mathrm{Lip}_0(M)^\ast$ with similar properties to those in $\mathcal{F}(M)$, and we show that it coincides with the support of the representing measure when such a measure exists. We deduce that the members of $\mathrm{Lip}_0(M)^\ast$ that can be expressed as the difference of two positive functionals admit a Jordan-like decomposition into a positive and a negative part.

description: Rust-infested and uninfested seedlots of 14 safflower (Carthamus tinctorius) entries (4 resistant lines, 4 moderately or fully susceptible lines, and six F1 hybrids from crosses between rust-susceptible females and rust-resistant males), were planted in replicated field trials. The four infested entries resistant to seedling rust incited by Puccinia carthami Cda. exhibited average stand losses of 2.4, 8.4, 18.4, and 27.7%. Stand reduction in the resistant entries was not greater than the inherent compensating ability of the surviving plants; consequently, the yield of these entries was not significantly reduced. Plots from the rusted seedlots of the moderately and fully susceptible entries had stand losses of 54.9, 79.5, 95.4, and 97.6%, and yielded significantly less than plots grown from uninfested seedlots. Stand reduction in these entries exceeded the inherent compensating ability of the surviving plants. Hybrid entries of rusted seedlots showed stand losses of 37.3, 47.4, 94.4, 61.7, 90.1, and 90.5%. Hybrids showed a better inherent compensating ability of surviving plants than pure lines. In the partial hybrid lines the undesirable selfs were eliminated by seedling rust, leaving a population composed of high yielding hybrid plants.

Publisher: name: Utah State University

description: Alfalfa-insect investigations, because of necessity, had been neglected in the province of Alberta during the war years. Work was resumed on this project in the spring of 1946 by the writer.
So much progress has been made in the field of insect pest control since the advent of war-born chlorinated hydrocarbons, that it was thought advisable to design an experiment which would test under Alberta conditions the results obtained in Utah where most of this type of research had been previously carried out, and would thus serve to bring investigations in this part of Canada up to date.
It is hoped that this study, which covers numerous, small, related problems, which will serve as a foundation on which future research studies of alfalfa-seed production in western Canada may be built. Most important problems of alfalfa-seed production in this region are:
1. Is the control of insect pests of alfalfa by an insecticide necessary?
2. If this is so, what insecticide, applied so as to minimise is poisonous effects on necessary bee pollinators of alfalfa, will give the best control results?
3. What effect have insect predators on the insect pests of alfalfa under natural field conditions, and what effect has the use of an insecticide, a chlorinated hydrocarbon, for example, on these insect predators?
4. What effect has the use of these insecticides on the amount of tripping and the condition of the bloom on treated alfalfa plants?
Research and development of commercially manufactured large GEM foils

description: © 2014 IEEE. The recently completed Forward GEM Tracker (FGT) of the STAR experiment at RHIC took advantage of commercially produced GEM foils based on double-mask chemical etching techniques. With future experiments proposing detectors that utilize very large-area GEM foils, there is a need for commercially available GEM foils. Double-mask etching techniques pose a clear limitation in the maximum size. In contrast, single-mask techniques developed at CERN would allow one to overcome those limitations. We report on results obtained using 10 × 10 cm2 and 40×40 cm2 GEM foils produced by Tech-Etch Inc. of Plymouth, MA, USA using single-mask techniques and thus the beginning for large GEM foil production on a commercial basis. A quality assurance procedure has been established through electrical and optical analyses via leakage current measurements and an automated high-resolution CCD scanner. The Tech-Etch foils show excellent electrical properties with leakage currents typically measured below 1 nA. The geometrical properties of the Tech-Etch single-mask foils were found to be consistent with one another, and were in line with geometrical specifications from previously measured double-mask foils. The single-mask foils displayed good inner and outer hole diameter uniformities over the entire active area.

description: Exoplanet and brown dwarf atmospheres commonly show signs of disequilibrium chemistry. In the James Webb Space Telescope era high resolution spectra of directly imaged exoplanets will allow the characterization of their atmospheres in more detail, and allow systematic tests for the presence of chemical species that deviate from thermochemical equilibrium in these atmospheres. Constraining the presence of disequilibrium chemistry in these atmospheres as a function of parameters such as their effective temperature and surface gravity will allow us to place better constrains in the physics governing these atmospheres. This paper is part of a series of works presenting the Sonora grid of atmosphere models (Marley et al 2021, Morley et al in prep.). In this paper we present a grid of cloud-free, solar metallicity atmospheres for brown dwarfs and wide separation giant planets with key molecular species such as CH4, H2O, CO and NH3 in disequilibrium. Our grid covers atmospheres with Teff~[500 K,1300 K], logg~[3.0,5.5] (cgs) and an eddy diffusion parameter of logKzz=2, 4 and 7 (cgs). We study the effect of different parameters within the grid on the temperature and composition profiles of our atmospheres. We discuss their effect on the near-infrared colors of our model atmospheres and the detectability of CH4, H2O, CO and NH3 using the JWST. We compare our models against existing MKO and Spitzer observations of brown dwarfs and verify the importance of disequilibrium chemistry for T dwarf atmospheres. Finally, we discuss how our models can help constrain the vertical structure and chemical composition of these atmospheres.

description: Per comprendere le vicende di una famiglia illustre e nobile il cui ruolo politico e sociale in Sicilia
si data alle soglie del XIV secolo, non possiamo astenerci dal ricordare i fatti e gli eventi che hanno
dominato la storia siciliana e determinato l’ascesa di Castelvetrano come centro signorile per
eccellenza.
E’ necessario, quindi, collocare geograficamente e storicamente l’isola per inserirla all’interno di un
preciso quadro socio-politico. All’origine della sua storia sono sicuramente da individuare sia il
legame intercorso nei secoli tra l’Asia e l’Europa, in particolare tra l’Asia Minore bizantina e l’area
mediterranea unificata proprio dall’impero di Bisanzio, sia le lotte per l’egemonia tra Chiesa e
Impero, (che abbastanza presto sarà impero d’Occidente) lotte che vedono entrambe le parti
impegnate a contendersi il ruolo di guida politica, morale e spirituale dell’intera cristianità
medievale, ritenendo ogni altro potere subordinato al proprio.
description: To understand the story of a noble and illustrious family whose political and social role in Sicily 
date is on the threshold of the fourteenth century, we can not refrain from remembering facts and events that have 
dominated the history of Sicily and led to the rise of Castelvetrano as a center for aristocratic 
excellence. 
E 'therefore necessary to place geographically and historically the island to slip into a 
specific socio-political context. At the origin of its history are definitely identify both the 
bond in the centuries that elapsed between Asia and Europe, in particular between the Byzantine Asia Minor and the area 
Mediterranean Unified own empire of Byzantium, and the struggles for hegemony between Church and 
Empire, (which will be soon enough empire of the West) that struggles see both sides 
committed to contend for the role of political leadership, moral and spiritual whole of Christianity 
medieval, considering all other powers subject to their own.
title: An Examination of a Putative System for the In Vitro Synthesis of Drosophila Tryptophan Pyrrolase
Creators: name: Phillips, John P.
Publisher: name: Utah State University
Year: 1967

description: A system, reported by Morrison (1964), for the in vitro synthesis of Drosophila tryptophan pyrrolase has been critically studied. This putative system is based on the addition of a Drosophila "RNA" extract to a Drosophila cell-free protein synthesizing system; the synthesized enzyme is then allowed to catalyze a specific reaction, the product of which is measured by direct adsorption.
The results of this study present a three-fold argument against the interpretation of synthesis of tryptophan pyrrolase in the Morrison in vitro system: (1) RNA from a null-allele, v36f, stimulated the same tryptophan pyrrolase "activity" in the in vitro system as Canton-s RNA. (2) The Bratton-Marshall test, a valid kynurenine assay in this system, detects no tryptophan pyrrolase activity in systems showing "activity" when assayed by the direct adsorption method used by Morrison. (3) An ascorbate dependent, nonenzymatic reaction, which produced a pseudotryptophan pyrrolase activity, was detected in the Morrison assay system. This pseudoactivity, which is eliminated by the substitution of 2-mercaptoethanol for ascorbate, was interpreted by Morrison as being representative of tryptophan pyrrolase produced in the in vitro system.
title: The Role of Brown Bears (Ursus Arctos) in Nutrient Transport into Forests near a Salmon Stream in Coastal British Columbia, Canada
Creators: name: Morris, Arthur

description: Nutrients from spawned salmon contribute to the fertility of rivers and riparian areas. Adjacent forests, even far from rivers, could receive substantial amounts of nitrogen and other nutrients from salmon. Since brown bears feed heavily on spawning salmon, bears probably influence the movement of nutrients from salmon into surrounding forests. Because salmon-derived nitrogen is high in 15N, increased isotopic enrichment is expected in forest soils and vegetation if this transport is occurring. Based on relative 15N enrichment of spawning areas, a quantitative estimate of marine-derived nitrogen (MDN) can be obtained using a linear two-source mixing model. To evaluate the reliability of MDN estimates based on such a two-source mixing model, we evaluated some assumptions used in mixing model calculations. We determined isotopic changes as nitrogen moved from salmon tissue into brown bear feces and soil where the bears were feeding on salmon near Knight Inlet, British Columbia. We also used a simulation model to evaluate fractionation's effect on MDN estimates. To evaluate dissemination of MDN by grizzly bears, we determined 15N of vegetation and soil from transects across bear trails and beds along the Koeye River, British Columbia. We expected to find the highest isotopic enrichment closest to bear trails and beds.
We found little difference (about 2%o) between δ15N of salmon tissue and δ15N of salmon-derived N in soil. However, δ15N in other areas was high, even exceeding δ15N of salmon tissue. Using a simulation model we found that fractionation of N losses from the soil caused gross (more than 70% in some cases) overestimates of MDN. It appeared that 15N fractionation could be large enough under natural conditions to prevent accurate quantification of MDN with a two-source mixing model.
Delta 15 N at bear trails and beds exceeded δ15N from several meters away on both sides (by an average of 1.5%0), and δ15N of a reference transect, supporting the assertion that bears move substantial amounts of MDN upslope. We calculated 5% to 56% MDN in soil within 10 m of bear trails and beds using δ15N data, compared to 14% MDN based on the 15N difference between reference and spawning sites.

description: A recent experiment reported the first rare-earth binary oxide superconductor LaO ($T_c $ $\sim$ 5 K) with a rock-salt structure [K. Kaminaga et al., J. Am. Chem. Soc. 140, 6754 (2018)]. Correspondingly, the underlying superconducting mechanism in LaO needs theoretical elucidation. Based on first-principles calculations on the electronic structure, lattice dynamics, and electron-phonon coupling of LaO, we show that the superconducting pairing in LaO belongs to the conventional Bardeen-Cooper-Schrieffer (BCS) type. Remarkably, the electrons and phonons of the heavy La atoms, instead of those of the light O atoms, contribute most to the electron-phonon coupling. We further find that both the biaxial tensile strain and the pure electron doping can enhance the superconducting $T_c$ of LaO. With the synergistic effect of electron doping and tensile strain, the $T_c$ could be even higher, for example, 11.11 K at a doping of 0.2 electrons per formula unit and a tensile strain of $4\%$. Moreover, our calculations show that the superconductivity in LaO thin film remains down to the trilayer thickness with a $T_c$ of 1.4 K.

Surface- and strain-tuning of the optical dielectric function in epitaxially grown CaMnO3

Subjects: cond-mat.mtrl-sci

description: © 2016 AIP Publishing LLC. We report a strong thickness dependence of the complex frequency-dependent optical dielectric function ϵ ̃ ( ω ) over a spectral range from 1.24 to 5 eV in epitaxial CaMnO3(001) thin films on SrTiO3(001), LaAlO3(001), and SrLaAlO4(001). A doubling of the peak value of the imaginary part of ϵ ̃ ( ω ) and spectral shifts of 0.5 eV for a given magnitude of absorption are observed. On the basis of experimental analyses and first-principles density functional theory calculations, contributions from both surface states and epitaxial strain to the optical dielectric function of CaMnO3 are seen. Its evolution with thickness from 4 to 63 nm has several regimes. In the thinnest, strain-coherent films, the response is characterized by a significant contribution from the free surface that dominates strain effects. However, at intermediate and larger thicknesses approaching the bulk-like film, strain coherence and partial strain relaxation coexist and influence ϵ ̃ ( ω ).

description: This volume covers Leg 39 of the cruises of the Drilling Vessel Glomar Challenger. Unlike most recent Deep Sea Drilling Project cruises, Leg 39 was not scientifically planned as a "theme" cruise, on which a number of sites are drilled to address a single scientific problem area. Rather, the general geographic area for drilling was dictated largely by logistics, since it was necessary to get Glomar Challenger from her recently completed Norwegian Sea drilling during the Northern Hemisphere summer to Cape Town in time to begin a third season of Antarctic and Southern Ocean drilling during the Southern Hemisphere summer. In order to optimize the ratio of drilling time to steaming time on the long cruise from Amsterdam to Cape Town, a cruise track to the western part of the South Atlantic was indicated. The result was the longest cruise to date in the DSDP program, both in terms of miles (9985) and days (72). Leg 39 scientific goals were to: 1) drill a presumed section of oceanic layer 3 in the offset region of the Vema Fracture Zone (Site 353); 2) collect a biostratigraphic section on the Ceará Rise (Site 354), determine the nature and age of a prominent reflector there, and determine the nature and age of basement; 3) date basement between magnetic anomalies 32 and 33 in the Argentine Basin (Site 358), and 33 and 34 in the Brazil Basin (Site 355); 4) obtain as complete sedimentary sections as time would permit at the Ceará Rise, Brazil Basin, the Argentine Basin, Sào Paulo Plateau (Site 356), and Rio Grande Rise (Site 357) to support the major objective of the cruise, improving our knowledge of paleocirculation changes and the overall geologic history of the South Atlantic Ocean; 5) determine the nature and age of prominent reflecting Horizons A and B in the Argentine Basin. Glomar Challenger departed Amsterdam on 6 October 1974 and arrived in Cape Town at first light on 17 December 1974. Glomar Challenger traveled 9895 miles and drilled 11 holes on seven sites.

description: In this work we apply the Fradkin-Vasiliev formalism based on the frame-like gauge invariant description of the massive and massless spin 2 to the construction of the cubic interactions vertices for massive spin 2 self-interaction as well as its gravitational interaction. In the first case we show that the vertex can be reduced (by field redefinitions) to the set of the trivially gauge invariant terms. There are four such terms which are not equivalent om-shell and do not contain more than four derivatives. Moreover, one their particular combination reproduces the minimal (with no more than two derivatives) vertex. As for the gravitational vertex, we show that due to the presence of the massless spin 2 there exist two abelian vertices (besides the three trivially gauge invariant ones) which are not equivalent to any trivially gauge invariant terms and can not be removed by field redefinitions. Moreover, their existence appears to be crucial for the possibility to reproduce the minimal two derivatives vertex.
