description: The bright, well-known K5 giant Aldebaran, alpha Tau, is probably the star with the largest number of direct angular diameter determinations, achieved over a long time by several authors using various techniques. In spite of this wealth of data, or perhaps as a direct result of it, there is not a very good agreement on a single angular diameter value. This is particularly unsettling if one considers that Aldebaran is also used as a primary calibrator for some angular resolution methods, notably for optical and infrared long baseline interferometry. Directly connected to Aldebaran's angular diameter and its uncertainties is its effective temperature, which also has been used for several empirical calibrations. Among the proposed explanations for the elusiveness of an accurate determination of the angular diameter of Aldebaran are the possibility of temporal variations as well as a possible dependence of the angular diameter on the wavelength. We present here a few, very accurate new determinations obtained by means of lunar occultations and long baseline interferometry. We derive an average value of 19.96+-0.03 milliarcseconds for the uniform disk diameter. The corresponding limb-darkened value is 20.58+-0.03 milliarcseconds, or 44.2+-0.9 R(sun). We discuss this result, in connection with previous determinations and with possible problems that may affect such measurements.

description: We study the near-threshold molecular and collisional physics of a strong $^{40}$K p-wave Feshbach resonance through a combination of measurements, numerical calculations, and modeling. Dimer spectroscopy employs both radio-frequency spin-flip association in the MHz band and resonant association in the kHz band. Systematic uncertainty in the measured binding energy is reduced by a model that includes both the Franck-Condon overlap amplitude and inhomogeneous broadening. Coupled-channels calculations based on mass-scaled $^{39}$K potentials compare well to the observed binding energies and also reveal a low-energy p-wave shape resonance in the open channel. Contrary to conventional expectation, we observe a nonlinear variation of the binding energy with magnetic field, and explain how this arises from the interplay of the closed-channel ramping state with the near-threshold shape resonance in the open channel. We develop an analytic two-channel model that includes both resonances as well as the dipole-dipole interactions which, we show, become important at low energy. Using this parameterization of the energy dependence of the scattering phase, we can classify the studied $^{40}$K resonance as broad. Throughout the paper, we compare to the well understood s-wave case, and discuss the significant role played by van der Waals physics. The resulting understanding of the dimer physics of p-wave resonances provides a solid foundation for future exploration of few- and many-body orbital physics.

description: We report on laser spectroscopic measurements on Li$^+$ ions in the experimental storage ring ESR at the GSI Helmholtz Centre for Heavy Ion Research. Driving the $2s\,^3\!{S}_1\;(F=\frac{3}{2}) \,\leftrightarrow\,2p\,^3\!P_2\;(F=\frac{5}{2}) \leftrightarrow 2s\,^3\!{S}_1\;(F=\frac{5}{2})$ $Λ$-transition in $^7$Li$^+$ with two superimposed laser beams it was found that the use of circularly polarized light leads to a disappearance of the resonance structure in the fluorescence signal. This can be explained by optical pumping into a dark state of polarized ions. We present a detailed theoretical analysis of this process that supports the interpretation of optical pumping and demonstrates that the polarization induced by the laser light must then be at least partially maintained during the round trip of the ions in the storage ring. Such polarized ion beams in storage rings will provide opportunities for new experiments, especially on parity violation.

Exploring spiritual and psychological issues at the end of life
Creators: name: Kuhl, David R.
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to explore spiritual and psychological issues as experienced by persons who know they have a terminal illness. An existentialphenomenological method was chosen to understand and articulate the structure and meaning underlying the experience of living with the knowledge that one has a terminal illness. The study had its genesis at the bedside(s) of people who were dying, yet living or living, yet dying. The experience of knowing one has a terminal illness serves to bring life and consciousness to those who may have otherwise continued to live unconsciously, to exist in a potentially weary and dormant state, oblivious to the fact that life was passing them by. The evidence of experience of knowing what it means to have a terminal illness exists in the words and expressions of the twenty-one people who graciously participated in this study as co-researchers. They have given testimony of their own experience to those of us who seek to understand that experience, to understand what it means to have a terminal illness, to confront one's end to life as it is known, to embrace life or to prepare to die. For some it was a single in-depth interview, for others there were numerous indepth interviews over the course of two to eleven months. Eight of the twenty-one coresearcher narratives were presented in this study. Each interview was recorded by audio and video tape, the former being used for transcription. Subsequently, transcriptions were reviewed for accuracy. As a measure of trustworthiness, themes were identified by the principal investigator and presented in the context of the narrative to the coresearchers who confirmed the data and validated the themes. Implications based on the themes identified in this study are presented under theory development, professional practice and future research. One of the strongest implications pertains to clinical practice in that the results could serve as the framework for a palliative care program which models palliative care as defined by the World Health Organization. The co-researchers were eager to tell their stories and to speak their truth with the hope that the care of persons with terminal illness would some day include care of people as whole persons—physical, psychological and spiritual.

description: Ly$α$ emission from galaxies can be utilized to characterize the ionization state in the intergalactic medium (IGM). We report our search for Ly$α$ emission at $z>7$ using a comprehensive Keck/MOSFIRE near-infrared spectroscopic dataset, as part of the Texas Spectroscopic Search for Ly$α$ Emission at the End of Reionization Survey. We analyze data from 10 nights of MOSFIRE observations which together target 72 high-$z$ candidate galaxies in the GOODS-N field, all with deep exposure times of 4.5-19 hr. Utilizing an improved automated emission-line search, we report 10 Ly$α$ emission lines detected ($>$4$σ$) at $z>7$, significantly increasing the spectroscopically confirmed sample. Our sample includes large equivalent-width (EW) Ly$α$ emitters ($>$50Å), and additional tentative Ly$α$ emission lines detected at 3 - 4$σ$ from five additional galaxies. We constrain the Ly$α$ EW distribution at $z\sim7.6$, finding a significant drop from $z\lesssim6$, suggesting an increasing fraction of neutral hydrogen (HI) in the IGM in this epoch. We estimate the Ly$α$ transmission through the IGM ($=$EW$_{z\sim\text{7.6}}$/EW$_{z\sim\text{2-6}}$), and infer an IGM HI fraction ($X_{\text{HI}}$) of $49^{+19}_{-19}\%$ at $z\sim7.6$, which is lower in modest tension ($>$1$σ$) with recent measurements at $z \sim$ 7.6. The spatial distribution of the detected Ly$α$ emitters implies the presence of a potential highly ionized region at $z\sim7.55$ which hosts four Ly$α$ emitters within a $\sim$ 40 cMpc spatial separation. The prominence of this ionized region in our dataset could explain our lower inferred value of $X_{\text{HI}}$, though our analysis is also sensitive to the chosen reference Ly$α$ EW distribution values and reionization models.

The renormalization of the energy-momentum tensor for an effective initial state

description: An effective description of an initial state is a method for representing the signatures of new physics in the short-distance structure of a quantum state. The expectation value of the energy-momentum tensor for a field in such a state contains new divergences that arise when summing over this new structure. These divergences occur only at the initial time at which the state is defined and therefore can be cancelled by including a set of purely geometric counterterms that also are confined to this initial surface. We describe this gravitational renormalization of the divergences in the energy-momentum tensor for a free scalar field in an isotropically expanding inflationary background. We also show that the back-reaction from these new short-distance features of the state is small when compared with the leading vacuum energy contained in the field.

description: Context: ALMA observations of Venus at 267 GHz have been presented in the literature that show the apparent presence of phosphine (PH3) in its atmosphere. Phosphine has currently no evident production routes on the planet's surface or in its atmosphere. Aims: The aim of this work is to assess the statistical reliability of the line detection by independent re-analysis of the ALMA data. Methods: The ALMA data were reduced as in the published study, following the provided scripts. First the spectral analysis presented in the study was reproduced and assessed. Subsequently, the spectrum was statistically evaluated, including its dependence on selected ALMA baselines. Results: We find that the 12th-order polynomial fit to the spectral passband utilised in the published study leads to spurious results. Following their recipe, five other >10 sigma lines can be produced in absorption or emission within 60 km/s from the PH3 1-0 transition frequency by suppressing the surrounding noise. Our independent analysis shows a feature near the PH3 frequency at a ~2 sigma level, below the common threshold for statistical significance. Since the spectral data have a non-Gaussian distribution, we consider a feature at such level as statistically unreliable that cannot be linked to a false positive probability. Conclusions: We find that the published 267-GHz ALMA data provide no statistical evidence for phosphine in the atmosphere of Venus.

description: The decorative/ornamental plant motif in jewellery: its potential to document narratives in the Australian craft context. A study in the form of an exhibition of jewellery shown at the Gold and Silversmithing Workshop, School of Art, The Australian National University, Childers Street, Acton, on 4th August, 2011, which comprises the outcome of the Studio Practice component (80%), including an Exegesis that documents the nature of the course of study undertaken, together with a Sub-Thesis (20%). The Studio Practice component focuses on research into plant forms from various sources and a variety of production technologies and materials, with the aim of creating jewellery that documents a personal narrative within the Australian context. The sub-thesis, divided into two parts, examines theoretical issues relating to the studio practice in the form of two separate essays. The first essay, 'Negotiating change', explores the relationship between the use of indigenous Australian plants in the garden and as motifs on crafted objects produced during the period 1850-1920, in order to understand the motivations for their use and the role they played in the process of people settling in a new land. The second essay, 'At home in the land', analyses how relationships to the natural environment and landscape of Australia have changed for many Australians since the 1960s. A study of works by three Australian studio jewellers, who use indigenous Australian plants as subject matter, supports the thesis that contemporary relationships with the landscape and bush reflect experiences of home that are intimate and immersive. -- provided by Candidate.

description: We carried out a detailed study of the temporal and broadband spectral behaviour of one of the brightest misaligned active galaxies in gamma-rays, NGC 1275 utilising 11 years of Fermi, and available Swift and AstroSat observations. Based on the cumulative flux distribution of the gamma-ray lightcurve, we identified four distinct activity states and noticed an increase in the baseline flux during the first three states. Similar nature of the increase in the average flux was also noticed in X-ray and UV bands. A large flaring activity in gamma-rays was noticed in the fourth state. The source was observed twice by AstroSat for shorter intervals (~days) during the longer observing periods (~years) state 3 and 4. During AstroSat observing periods, the source gamma-ray flux was higher than the average flux observed during longer duration states. The increase in the average baseline flux from state 1 to state 3 can be explained considering a corresponding increase of jet particle normalisation. The inverse Comptonisation of synchrotron photons explained the average X-ray and gamma-ray emission by jet electrons during the first three longer duration states. However, during the shorter duration AstroSat observing periods, a shift of the synchrotron peak frequency was noticed, and the synchrotron emission of jet electrons well explained the observed X-ray flux.

description: Due to the strategic economic role that Da Nang City plays in the development of Central Vietnam, and the advancement of the whole country of Vietnam and the Mekong Region, this city has become the main receiver and focal point of Japan's Official Development Assistance (ODA). This research analyzes the impacts of Japan's ODA projects over Vietnam's development by closely studying the ODA's experiences of Da Nang City. Two representative projects that were funded using Japan's ODA in Da Nang City were chosen as case studies to analyze the crucial role of Japan's ODA projects in the economic and social development of Da Nang City, Vietnam. Because of the importance of Japan's ODA projects in the overall development of Vietnam and in various localities, Vietnam's locality, Japan's ODA has greatly influenced the diplomatic relationships that exist between Vietnam and Japan. This research illustrates how Japan's ODA has been used in furthering the foreign policies of Vietnam and Japan and studies its impacts on the two countries' diplomatic relationships. The findings of this research have helped the author in making some recommendations on the effective handling of Japan's ODA at the local and national scales. The findings and recommendations in this study are expected to provide useful information which could help in the efficient management of ODA in Vietnam, and consequently lead to the improvement of the diplomatic relationships between Vietnam and Japan.

description: We show that the current search for Lorentz invariance violation (LIV) in the summed energy spectra of electrons in $2νββ$ decay can be extended by investigating the single electron spectra and the angular correlation between the emitted electrons. We derive and calculate the LIV contributions to these spectra associated with the anisotropic part of the countershaded operator and controlled through the coefficient $\mathring{a}_{\text{of}}^{(3)}$ and discuss possible signatures that may be probed in experiments. First, we show that some distortion occurs in the single electron spectrum, maximal at small electron energies. Then, we show that other LIV effects may be highlighted by analysing the angular correlation spectra and the ratio between the Standard Model Extension (SME) electron spectra and their Standard Model (SM) forms. We found that these LIV signatures depend on the magnitude of $\mathring{a}_{\text{of}}^{(3)}$, manifest differently for positive and negative values of this coefficient, and become more pronounced as the electron energy approaches the $Q$-value. Finally, we propose an alternative, new method to constrain $\mathring{a}_{\text{of}}^{(3)}$ through the measurement of the angular correlation coefficient. Using this method, and considering only statistical uncertainties, we obtain bounds of $\mathring{a}_{\text{of}}^{(3)}$ at the level of present ones, obtained from summed energy spectra. We show that future experiments can improve these limits significantly. Our study is performed for $^{100}$Mo, but the results hold qualitatively for other nuclei that undergo a double-beta decay. We hope our results will provide additional motivation for the LIV analyses performed in DBD experiments.

description: We present the first detailed case study using quadratic estimators (QE) to diagnose and remove systematics present in observed Cosmic Microwave Background (CMB) maps. In this work we focus on the temperature to polarization leakage. We use an iterative QE analysis to remove systematics, in analogy to de-lensing, recovering the primordial B-mode signal and the systematic maps. We introduce a new Gaussian filtering scheme crucial to stable convergence of the iterative cleaning procedure and validate with comparisons to semi-analytical forecasts. We study the limitations of this method by examining its performance both on idealized simulations and on more realistic, non-ideal simulations, where we assume varying de-lensing efficiencies. Finally, we quantify the systematic cleaning efficiency by presenting a likelihood analysis on the tensor to scalar ratio, $r$, and demonstrate that the blind cleaning results in an un-biased measurement of $r$, reducing the systematic induced B-mode power by nearly two orders of magnitude.

description: Logic locking aims to protect the intellectual property (IP) of integrated circuit (IC) designs throughout the globalized supply chain. The SAIL attack, based on tailored machine learning (ML) models, circumvents combinational logic locking with high accuracy and is amongst the most potent attacks as it does not require a functional IC acting as an oracle. In this work, we propose UNSAIL, a logic locking technique that inserts key-gate structures with the specific aim to confuse ML models like those used in SAIL. More specifically, UNSAIL serves to prevent attacks seeking to resolve the structural transformations of synthesis-induced obfuscation, which is an essential step for logic locking. Our approach is generic; it can protect any local structure of key-gates against such ML-based attacks in an oracle-less setting. We develop a reference implementation for the SAIL attack and launch it on both traditionally locked and UNSAIL-locked designs. In SAIL, a change-prediction model is used to determine which key-gate structures to restore using a reconstruction model. Our study on benchmarks ranging from the ISCAS-85 and ITC-99 suites to the OpenRISC Reference Platform System-on-Chip (ORPSoC) confirms that UNSAIL degrades the accuracy of the change-prediction model and the reconstruction model by an average of 20.13 and 17 percentage points (pp) respectively. When the aforementioned models are combined, which is the most powerful scenario for SAIL, UNSAIL reduces the attack accuracy of SAIL by an average of 11pp. We further demonstrate that UNSAIL thwarts other oracle-less attacks, i.e., SWEEP and the redundancy attack, indicating the generic nature and strength of our approach. Detailed layout-level evaluations illustrate that UNSAIL incurs minimal area and power overheads of 0.26% and 0.61%, respectively, on the million-gate ORPSoC design.

description: In random sequential adsorption (RSA), objects are deposited randomly, irreversibly, and sequentially; attempts leading to an overlap with previously deposited objects are discarded. The process continues until the system reaches a jammed state when no further additions are possible. We analyze a class of lattice RSA models in which landing on an empty site in a segment is allowed when at least $b$ neighboring sites on the left and the right are unoccupied. For the minimal model ($b=1$), we compute the full counting statistics of the occupation number. We reduce the determination of the full counting statistics to a Riccati equation that appears analytically solvable only when $b=1$. We develop a perturbation procedure which, in principle, allows one to determine cumulants consecutively, and we compute the variance of the occupation number for all $b$.

End-point of the rp process and periodic gravitational wave emission
Creators: name: Jones, P. B.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The general end-point of the rp process in rapidly accreting neutron stars is believed to be a surface distribution of matter whose nuclear composition may depend on position. Its evolution during compression beyond the neutron-drip threshold density is determined by the presence of nuclear formation enthalpy minima at the proton closed shells. At threshold, a sequence of weak interactions with capture or emission of neutron pairs rapidly transform nuclei to the most accessible proton closed shell. Therefore, angular asymmetries in nuclear composition present in accreted matter at neutron drip are preserved during further compression to higher densities provided transition rates between closed shells are negligible. Although it has been confirmed that this condition is satisfied for predicted internal temperatures and for the formation enthalpy distribution used in this work, it would not be so if the true enthalpy differences between maxima and minima in the distribution were a factor of two smaller. For this reason, it does not appear possible to assert with any confidence that position-dependent surface composition can lead to significant angle-dependence of the equation of state and to potentially observable gravitational radiation. The effect of non-radial internal temperature gradients on angle-dependency of the equation of state is also not quantifiable.

Influence of dietary fatty acids and positional distribution of dietary fatty acids on plasma lipids, visual acuity and cognitive development in term infants
Creators: name: Nelson, Carolanne Michele

description: Arachidonic acid (20:4n-6) and 22:6n-3 are incorporated into the CNS during development. Deficiency of 18:3n-3 during development reduces 22:6n-3 and alters function of the retina and brain. As of 1999, infant formulas in North America contain 18:2n-6 and 18:3n-3, but not 20:4n-6 or 22:6n-3, whereas formulas in Europe, Asia and South American may contain Ion-chain fatty acids from sources that include fish oils, egg phospholipids and single cell oils. It is not known if 20:4n-6 and 22:6n-3 are essential nutrients for normal brain and retina development in term infants. Human milk TG has 16:0 preferentially esterified at the sn-2 position, whereas in infant formula 16:0 is predominantly at the sn-1,3 position. The effect of milk and formula TG fatty acid distribution on plasma lipid fatty acids is not known. These studies determined whether preferential looking acuity or novelty preference differs between breast-fed infants and infants fed formula with 18:3n-3 (1% of energy) and no 20:4n-6 or 22:6n-3. The influence of the milk and formula TG fatty acid distribution on the distribution of fatty acids in plasma lipids and lipoproteins was also determined in a randomized double-blind study with infants fed formula with 16:0 preferentially esterified at the 2 position, a standard formula or breast-fed. These studies found no association between visual acuity and erythrocyte or plasma PL 22:6n-3 at three mo, and no difference in visual acuity at any age to 18 mo between breast-fed and formula-fed infants. 16:0 was found to be higher in the plasma TG 2 position of the breast-fed infants and the infants fed the synthesized TG formula than infants fed the standard formula. These studies also showed about 50% of the 2 position 16:0 of milk and synthesized TG formula was conserved through digestion, absorption, reesterification to TG and secretion in chylomicron TG. Furthermore, the distribution of TG in milk and formula did influence plasma lipids, notably, 18:3n-3. Analysis of the lipoprotein lipids showed high 20:4n-6 and 22:6n-3 in lysoPL, 18:2n-6 and 18:3n-3 in albumin fatty acids, and 20:4n-6 and 22:6n-3 in HDL PL. The role of these lipids in n-6 and n-3 fatty acid delivery to brain remains to be determined.

The Parallax of Omega Centauri Measured from Gaia EDR3 and a Direct, Geometric Calibration of the Tip of the Red Giant Branch and the Hubble Constant

description: We use data from the ESA Gaia mission Early Data Release 3 (EDR3) to measure the trigonometric parallax of $ω$ Cen, the first high precision parallax measurement for the most massive globular cluster in the Milky Way. We use a combination of positional and high quality proper motion data from EDR3 to identify over 100,000 cluster members, of which 67,000 are in the magnitude and color range where EDR3 parallaxes are best calibrated. We find the estimated parallax to be robust, demonstrating good control of systematics within the color-magnitude diagram of the cluster. We find a parallax for the cluster of $0.191\pm0.001$ (statistical) $\pm0.004$ (systematic) mas (2.2\% total uncertainty) corresponding to a distance of $5.24\pm0.11$ kpc. The parallax of $ω$ Cen provides a unique opportunity to directly and geometrically calibrate the luminosity of the Tip of the Red Giant Branch (TRGB) because it is the only cluster with sufficient mass to provide enough red giant stars, more than 100 one magnitude below the tip, for a precise, model-free measurement of the tip. Combined with the pre-existing and most widely-used measurements of the tip and foreground Milky Way extinction, we find $M_{I,TRGB}=-3.97\pm0.06$ mag for the $I$-band luminosity of the blue edge. Using the TRGB luminosity calibrated from the Gaia EDR3 parallax of $ω$ Cen to calibrate the luminosity of SNIa results in a value for the Hubble constant of $H_0=72.1\pm2.0$ km s$^{-1}$ Mpc$^{-1}$. We make the data for the stars in $ω$ Cen available electronically and encourage independent analyses of the results presented here.

description: The decay channel J/ψ--> γπ^+ π^- η^{\prime} is analyzed using a sample of 5.8\times 10^7 Jψevents collected with the BESII detector. A resonance, the X(1835), is observed in the π^+ π^- η^{\prime} invariant mass spectrum with a statistical significance of 7.7 σ. A fit with a Breit-Wigner function yields a mass M = 1833.7 \pm 6.1(stat) \pm 2.7(syst) MeV/c^2, a width Γ= 67.7 \pm 20.3(stat) \pm 7.7(syst) MeV/c^2 and a product branching fraction B(J/ψ--> γX) B(X --> π^+ π^- η^{\prime}) = (2.2 \pm 0.4(stat) \pm 0.4(syst)) \times 10^{-4}. The mass and width of the X(1835) are not compatible with any known meson resonance. Its properties are consistent with expectations for the state that produces the strong p\bar{p} mass threshold enhancement observed in the Jψ-->γp \bar{p} process at BESII.

description: About 2.1 million farms operated 854 million acres of land in the contiguous United States in 1991. The average land operated was 407 acres per reporting farm. The value of gross farm sales, a measure of what the farm has produced during the year, was estimated at $145.5 billion, or $69,298 per farm. Gross cash farm income, a measure of cash actually received by the farm business during the year, totaled $130.7 billion, with 44 percent from crop sales, 42 percent from livestock sales, 9 percent from other farm-related income, and 5 percent from government payments. This report, the 16th Annual Family Farm Report to Congress, is the second in a series of reports designed to provide annual data on the major structural and financial characteristics of the farm sector as portrayed by the Farm Costs and Returns Survey.

Focusing of laser-generated ion beams by a plasma cylinder: similarity theory and the thick lens formula

description: It is shown that plasma-based optics can be used to guide and focus highly divergent laser-generated ion beams. A hollow cylinder is considered, which initially contains a hot electron population. Plasma streaming toward the cylinder axis maintains a focusing electrostatic field due to the positive radial pressure gradient. The cylinder works as thick lens, whose parameters are obtained from similarity theory for freely expanding plasma in cylindrical geometry. Because the lens parameters are energy dependent, the lens focuses a selected energy range of ions and works as a monochromator. Because the focusing is due to the quasineutral part of the expanding plasma, the lens parameters depend on the hot electron temperature $T_e$ only, and not their density.
