A Differential Spectroscopic Analysis of 16 Cygni A and B
Creators: name: Laws, Chris

Publisher: name: arXiv
Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We utilize high-resolution, high signal-to-noise spectra to perform a differential analysis of Fe abundances in the common proper-motion pair 16 Cyg A and B. We confirm that both stars are slightly metal-rich compared to the Sun, and we show for the first time that the primary is enhanced in Fe relative to the secondary by a significant amount. We find Delta[Fe/H]=+0.025\pm0.009. This tends to support the ``self-pollution'' scenario proposed by Gonzalez (1998), though lack of a complete understanding of small primordial metallicity variations among binaries and open cluster members prevents a definitive conclusion.

description: A large class of gapped phases of matter can be described by topological finite group gauge theories. In this paper we show how such gauge theories possess a higher-group global symmetry, which we study in detail. We derive the $d$-group global symmetry and its 't Hooft anomaly for topological finite group gauge theories in $(d+1)$ space-time dimensions, including non-Abelian gauge groups and Dijkgraaf-Witten twists. We focus on the 1-form symmetry generated by invertible (Abelian) magnetic defects and the higher-form symmetries generated by invertible topological defects decorated with lower dimensional gauged symmetry-protected topological (SPT) phases. We show that due to a generalization of the Witten effect and charge-flux attachment, the 1-form symmetry generated by the magnetic defects mixes with other symmetries into a higher group. We describe such higher-group symmetry in various lattice model examples. We discuss several applications, including the classification of fermionic SPT phases in (3+1)D for general fermionic symmetry groups, where we also derive a simpler formula for the $[O_5] \in H^5(BG, U(1))$ obstruction that has appeared in prior work. We also show how the $d$-group symmetry is related to fault-tolerant non-Pauli logical gates and a refined Clifford hierarchy in stabilizer codes. We discover new logical gates in stabilizer codes using the $d$-group symmetry, such as a Controlled-Z gate in (3+1)D $\mathbb{Z}_2$ toric code.

description: We propose here a \emph{novel} method which singles out the \emph{a priori} unavoidable dependence on the underlying cosmological model when extracting parameter constraints, providing robust limits which only depend on the considered dataset. Interestingly, when dealing with several possible cosmologies and interpreting the Bayesian preference in terms of the Gaussian statistical evidence, the preferred model is much less favored than when only two cases are compared. As a working example, we apply our approach to the cosmological neutrino mass bounds, which play a fundamental role not only in establishing the contribution of relic neutrinos to the dark matter of the Universe, but also in the planning of future experimental searches of the neutrino character and of the neutrino mass ordering.

description: The function of vault RNAs remains unclear. The human genome encodes four vault RNAs: vtRNA1-1, 1-2, 1-3 and 2-1. Previous literature suggests that vault RNAs protect cells from apoptosis, regulate autophagy, and stimulate the immune response during viral infection. However, studies have shown that at least some of these functions are contingent on the presence of a 5’ triphosphate moiety. DUSP11 (dual specificity phosphatase 11) is an RNA triphosphatase that removes the gamma and beta phosphates from the 5’ end of RNAs. Regulation of phosphorylation status is not fully characterized and may impact downstream pathways that vault RNAs are involved in. Here, I hypothesize that DUSP11 plays a key role in regulating vault RNA levels and consequently, impacts the function of vault RNAs. I demonstrate that DUSP11 knockout results in an increased abundance of vault RNAs. Moreover, results indicate that DUSP11 mediated removal of the triphosphate on vault RNAs results in their degradation over time. Preliminary data suggests that DUSP11 is an important regulator of vault RNAs.

description: We investigate quantum depinning of the one-dimensional (1D) commensurate charge-density wave (CDW) in the presence of one impurity theoretically. Quantum tunneling rate below but close to the threshold field is calculated at absolute zero temperature by use of the phase Hamiltonian within the WKB approximation. We show that the impurity can induce localized fluctuation and enhance the quantum depinning. The electric field dependence of the tunneling rate in the presence of the impurity is different from that in its absence.

description: People with serious mental illness (SMI) have mortality rates 2–3-times higher than the general population, mostly driven by physical health conditions. Behavioural health homes (BHHs) integrate primary care into specialty mental healthcare settings with the goal of improving management of physical health conditions among people with SMI. Implementation and evaluation of BHH models is increasing in the US. This comprehensive review summarized the available evidence on the effects of BHHs on physical healthcare delivery and outcomes and identified perceived barriers and facilitators that have arisen during implementation to-date. This review found 11 studies reporting outcomes data on utilization, screening/monitoring, health promotion, patient-reported outcomes, physical health and/or costs of BHHs. The results of the review suggest that BHHs have resulted in improved primary care access and screening and monitoring for cardiovascular-related conditions among consumers with SMI. No significant effect of BHHs was reported for outcomes on diabetes control, weight management, or smoking cessation. Overall, the physical health outcomes data is limited and mixed, and implementation of BHHs is variable.

description: Ocean uptake of anthropogenic CO2 causes ocean acidification (OA), which not only decreases the calcification rate, but also impairs the formation of calcareous shells or tubes in marine invertebrates such as the dominant biofouling tubeworm species, Hydroides elegans. This study examined the ability of tubeworms to resume normal tube calcification when returned to ambient pH 8.1 from a projected near-future OA level of pH 7.8. Tubeworms produced structurally impaired and mechanically weaker calcareous tubes at pH 7.8 compared to at pH 8.1, but were able to recover when the pH was restored to ambient levels. This suggests that tubeworms can physiologically recover from the impacts of OA on tube calcification, composition, density, hardness and stiffness when returned to optimal conditions. These results help understanding of the progression of biofouling communities dominated by tubeworms in future oceans with low pH induced by OA.

description: We consider the $\mathrm{O}(3)$ non-linear sigma-model, composed of three real scalar fields with a standard kinetic term and with a symmetry breaking potential in four spacetime dimensions. We show that this simple, geometrically motivated model, admits both self-gravitating, asymptotically flat, non-topological solitons and hairy black holes, when minimally coupled to Einstein's gravity, $without$ the need to introduce higher order kinetic terms in the scalar fields action. Both spherically symmetric and spinning, axially symmetric solutions are studied. The solutions are obtained under a ansatz with oscillation (in the static case) or rotation (in the spinning case) in the internal space. Thus, there is symmetry non-inheritance: the matter sector is not invariant under the individual spacetime isometries. For the hairy black holes, which are necessarily spinning, the internal rotation (isorotation) must be synchronous with the rotational angular velocity of the event horizon. We explore the domain of existence of the solutions and some of their physical properties, that resemble closely those of (mini) boson stars and Kerr black holes with synchronised scalar hair in Einstein-(massive, complex)-Klein-Gordon theory.

description: The increase in the number of medical courses, from 179 to 323, between 2000 and 2018, and with the increasing technological evolution is expected a growth also in the complexity of the facilities and the infrastructure of the IES laboratories. This raises a question as to which is the best professional qualification that could assume the responsibility in the management of this equipment? Considering the period between 2000 and 2018, 18 Biomedical Engineering courses were created. This professional when works in a clinical environment is called as Clinical Engineer. Clinical Engineers are responsible for managing the entire life cycle of dental-medical-hospital equipment. Thus, in addition to monitoring the installation, maintenance and downtime of dental-medical equipment, they are called to respond to the growing demand for cost control, optimization of resource utilization, compliance with regulatory requirements, increased user safety and awareness of human error, and the management of an increasingly complex technological environment. Therefore, the clinical engineering professional could be used to manage the equipment park of the health laboratories at the higher education institutions (IES).

description: Transcranial magnetic stimulation combined with electroencephalography (TMS-EEG) is widely used to study the reactivity and connectivity of brain regions for clinical or research purposes. The electromagnetic pulse of the TMS device generates at the instant of administration an artifact of large amplitude and a duration up to tens of milliseconds that overlaps with brain activity. Methods for TMS artifact correction have been developed to remove the artifact and recover the underlying, immediate response of the cerebral cortex to the magnetic stimulus. In this study, three such algorithms are evaluated. Since there is no ground truth for the masked brain activity, pilot data formed from the superposition of the isolated TMS artifact on the EEG brain activity are used to evaluate the performance of the algorithms. Different scenarios of TMS-EEG experiments are considered for the evaluation: TMS at resting state, TMS inducing epileptiform discharges and TMS administered during epileptiform discharges. We show that a proposed gap filling method is able to reproduce qualitative characteristics and in many cases closely resemble the hidden EEG signal. Finally, shortcomings of the TMS correction algorithms as well as the pilot data approach are discussed.

Reducing the prevalence of compassion fatigue in emergency department nurses through resilience training
Creators: name: Abedullah, Mariem
Publisher: name: No Publisher Supplied
Year: 2021

description: Compassion fatigue is exhaustion that limits the ability of caring relationships. Emergency department nurses deal with high stress situations that involve physical and emotional challenges that may result in compassion fatigue. Due to the challenges of the demands faced by emergency department nurses, compassion fatigue is a vast issue, which impacts the quality of care provided. Compassion fatigue affects patient satisfaction and staff turnover, ultimately leading to the nursing shortage. Therefore, it is a problem worth investigating and working to resolve.Methodology: Resilience techniques such as self-care strategies (i.e, sleep, adequate hydration and nutrition) as well as guided meditation and self-affirmation were discussed in a one-hour resilience training to help emergency department nurses in a level two trauma hospital develop resiliency techniques to overcome compassion fatigue. Compassion fatigue was scored on a Professional Quality of Life tool developed by Hudnall Stamm (2009) before and after the training to assess the effectiveness of the training on emergency department nurses. Results: A Mann Whitney U statistical analysis showed statistically significant results for the subsets of burnout, compassion satisfaction, and secondary traumatic stress (p = .000). The mean scores for each subset of the Professional Quality of Life tool have also improved post-intervention.Conclusion: The results of this project correlate with evidence in the literature, stating that resiliency training works to improve compassion fatigue by improving compassion satisfaction and decreasing burnout and secondary traumatic stress. The resilience training for this project used strategies that include self-care, mentoring, and exercise, which gave nurses different techniques to improve resiliency such as guided meditation and tips on improving their health and lifestyle. It was concluded that resilience training has a positive effect on reducing the prevalence of compassion fatigue in emergency department nurses.
A Quantum Algorithm Framework for Discrete Probability Distributions with Applications to Rényi Entropy Estimation

description: Estimating statistical properties is fundamental in statistics and computer science. In this paper, we propose a unified quantum algorithm framework for estimating properties of discrete probability distributions, with estimating Rényi entropies as specific examples. In particular, given a quantum oracle that prepares an $n$-dimensional quantum state $\sum_{i=1}^{n}\sqrt{p_{i}}|i\rangle$, for $α>1$ and $0<α<1$, our algorithm framework estimates $α$-Rényi entropy $H_α(p)$ to within additive error $ε$ with probability at least $2/3$ using $\widetilde{\mathcal{O}}(n^{1-\frac{1}{2α}}/ε+ \sqrt{n}/ε^{1+\frac{1}{2α}})$ and $\widetilde{\mathcal{O}}(n^{\frac{1}{2α}}/ε^{1+\frac{1}{2α}})$ queries, respectively. This improves the best known dependence in $ε$ as well as the joint dependence between $n$ and $1/ε$. Technically, our quantum algorithms combine quantum singular value transformation, quantum annealing, and variable-time amplitude estimation. We believe that our algorithm framework is of general interest and has wide applications.

description: We report a new technique for fabricating metallic electrodes on insulating substrates with separations on the 1 nm scale. The fabrication technique, which combines lithographic and electrochemical methods, provides atomic resolution without requiring sophisticated instrumentation. The process is simple, controllable, reversible, and robust, allowing rapid fabrication of electrode pairs with high yield. We expect the method to prove useful in interfacing molecular-scale structures to macroscopic probes and electronic devices .

description: Optical spectroscopic studies of emission lines in black-hole candidates can help us investigate state transitions in those systems. Changes in the optical line profiles reflect changes in the geometry of the accretion flow, usually associated with X-ray state transitions in the inner region. We identify at least four optical states in the black-hole candidate GRO J1655-40 in outburst, and two optical states in GX339-4.

description: Low-mass stars exhibit substantial pre-main sequence evolution during the first ~100 Myrs of their lives. Thus, young M-type stars are prime targets for isochronal dating, especially in young moving groups (YMGs), which contain large amounts of stars in this mass and age range. If the mass and luminosity of a star can both be directly determined, this allows for a particularly robust isochronal analysis. This motivates in-depth studies of low-mass binaries with spatially resolvable orbits, where dynamical masses can be derived. Here we present the results of an observing campaign dedicated to orbital monitoring of AB Dor Ba/Bb, which is a close M-dwarf pair within the quadruple AB Dor system. We have acquired eight astrometric epochs with the SPHERE/ZIMPOL and NACO instruments, which we combine with literature data to improve the robustness and precision for the orbital characterization of the pair. We find a system mass 0.66+/-0.12 Msun and bolometric luminosities in log(L/Lsun) of -2.02+/-0.02 and -2.11 +/- 0.02 for AB Dor Ba and Bb, respectively. These measurements are combined with other YMG pairs in the literature to start building a framework of empirical isochrones in mass-luminosity space. This can be used to calibrate theoretical isochrones and to provide a model-free basis for assessing relative stellar ages. We note a tentative emerging trend where the youngest moving group members are largely consistent with theoretical expectations, while stars in older associations such as the AB Dor moving group appear to be systematically underluminous relative to isochronal expectations.

description: We are able to disentagle the effects of the intraband and interband parts of the bulk dielectric function on the bare dielectric anisotropy of the surface. We show how the position, sign and amplitude of the structures observed in such spectra depend on the above quantities. The lineshape of all the calculated structures agree very well with the ones observed experimentally for samples treated by suitable surface cleaning. In particular, we reproduce the observed single peak structure of Ag at high energy, found to represent a state of the clean surface different from the one giving the originally observed double peak structure. This results is not reproduced by the 'local field' model.

Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: It has recently been proven that certain effective wavefunctions in fractional quantum mechanics and condensed matter do not have a locally conserved current; as a consequence, their coupling to the electromagnetic field leads to extended Maxwell equations, featuring non-local, formally simple additional source terms. Solving these equations in general form or finding analytical approximations is a formidable task, but numerical solutions can be obtained by performing some bulky double-retarded integrals. We focus on concrete experimental situations which may allow to detect an anomalous quasi-static magnetic field generated by these (collective) wavefunctions in cuprate superconductors. We compute the spatial dependence of the field and its amplitude as a function of microscopic parameters including the fraction $η$ of supercurrent that is not locally conserved in Josephson junctions between grains, the thickness $a$ of the junctions and the size $\varepsilon$ of their current sinks and sources. The results show that the anomalous field is actually detectable at the macroscopic level with sensitive experiments, and can be important at the microscopic level because of virtual charge effects typical of the extended Maxwell equations.

description: Machine Learning models capable of handling the large datasets collected in the financial world can often become black boxes expensive to run. The quantum computing paradigm suggests new optimization techniques, that combined with classical algorithms, may deliver competitive, faster and more interpretable models. In this work we propose a quantum-enhanced machine learning solution for the prediction of credit rating downgrades, also known as fallen-angels forecasting in the financial risk management field. We implement this solution on a neutral atom Quantum Processing Unit with up to 60 qubits on a real-life dataset. We report competitive performances against the state-of-the-art Random Forest benchmark whilst our model achieves better interpretability and comparable training times. We examine how to improve performance in the near-term validating our ideas with Tensor Networks-based numerical simulations.

 Material examined. 2 specimens. Lombok Is. NSMT E-8249 (2 specimens), Kodek, February15, 1994.
 Description (larger specimen). Centrodorsal discoidal, 7 mm across, 3 mm thick, with cirrus sockets in 1–2 irregular rows and flat aboral pole. Cirri stout, XXIII, 33–35, 25– 30 mm long. Cirrals wholly shorter than wide; beyond about 11 th with prominent aboral spine. Radials wholly concealed by centrodorsal. IBr 2: Ibr 1 oblong, in contact laterally; Ibr 2 (axil) low triangular, free laterally. IIBr 4(3+4). Arms stout, 16, 135 mm long; first syzygy at br 3+4; br 4 –br 10 about 3 times wider than long with parallel articulation, beyond br 10 wedge-shaped. P 3 longest, stiffened, 20 mm long, of 30 segments; proximal pinnulars shorter than wide with a keel toward tip. P 2 similar to P 3, but slightly shorter. P 2 and P 3 much longer and stouter than PII and P 1.
 Remarks. Four Heterometra species, namely H. variipinna (Carpenter, 1882), H. affinis (Hartlaub, 1890), H. amboinae (A. H. Clark, 1912a), and H. sarae A. H. Clark, 1941, were recorded from Ambon (A. H. Clark 1941). In these 4 species, H. amboinae is the most closely related to H. sarae in sharing excessively short middle-distal brachials. According to A. H. Clark (1941: 230–232), brachials beyond br 4 are 3–4 times wider than long in H. amboinae, while 6–8 times wider than long in H. sarae. Based on these characteristics, present specimens were identified with H. amboinae.
 Distribution. Sri Lanka, Singapore, Indonesia (A. H. Clark 1941; A. M. Clark and Rowe 1971). Depth range: 0–50 m (A. H. Clark 1941).

With this survey, we deliver far-IR surface brightness distributions of roughly 10' x 40' or 10' x 20' areas of the sky around the target evolved stars in the four FIS bands at 65, 90, 140, and 160 microns. Our objectives are to characterize the far-IR surface brightness distributions of the cold dust component in the circumstellar dust shells, from which we derive the amount of cold dust grains as low as 20 K and empirically establish the history of the early mass loss history. In this first installment of the series, we introduce the project and its aims, describe the observations, data reduction, and surface brightness correction process, and present the entire data set along with the results of integrated photometry measurements (i.e., the central source and circumstellar dust shell altogether). We find that (1) far-IR emission is detected from all but one object at the spatial resolution about 30" - 50" in the corresponding bands, (2) roughly 60 - 70 % of the target sources show some extension, (3) previously unresolved nearby objects in the far-IR are now resolved around 28 target sources, (4) the results of photometry measurements are reasonable with respect to the entries in the AKARI/FIS Bright Source Catalogue, despite the fact that the targets are assumed to be point-sources when catalogue flux densities were computed, and (5) an IR two-color diagram would place the target sources in a roughly linear distribution that may correlate with the age of the circumstellar dust shell and can potentially be used to identify which targets are more extended than others.

description: Local density calculations of the electronic structure of FeSi, FeSi_{1-x}Al_x and Fe_{1-x}Ir_xSi systems in the B20 structure are presented. Pure FeSi has a semi-conducting gap of 6 mRy at 0 K. Effects of temperature (T) in terms of electronic and vibrational excitations are included. Various measurable properties, such as magnetic susceptibility chi(T), electronic specific heat C(T), thermoelectric power S(T), relative variations in resistivity rho(T), and peak positions in the density-of-states (DOS) are calculated. The feedback from vibrational disorder onto the electronic structure is found to be essential for a good description of most properties, although the results for S(T) in undoped FeSi can be described up to about 150 K without considerations of disorder. Above this T, only the filling of the gap due to disorder accompanied by exchange enhancement, can explain the large susceptiblity. The overall good agreement with experimental data for most properties in doped and pure FeSi suggests that this system is well described by LDA even at large T. Doped FeSi can be described quite well from rigid-band shifts of the Fermi energy on the DOS of pure FeSi. Spin-polarization in Ir doped FeSi leads to a semi-metallic magnetic state at low T.

description: A growing number of both galactic and extragalactic supernova remnants show non-thermal (non-plerionic) emission in the X-ray band. New synchrotron models, realized as SRESC and SRCUT in XSPEC 11, which use the radio spectral index and flux as inputs and include the full single-particle emissivity, have demonstrated that synchrotron emission is capable of producing the spectra of dominantly non-thermal supernova remnants with interesting consequences for residual thermal abundances and acceleration of particles. In addition, these models deliver a much better-constrained separation between the thermal and non-thermal components, whereas combining an unconstrained powerlaw with modern thermal models can produce a range of acceptable fits. While synchrotron emission can be approximated by a powerlaw over small ranges of energy, the synchrotron spectrum is in fact steepening over the X-ray band. Having demonstrated that the integrated spectrum of SN 1006, a remnant dominated by non-thermal emission, is well described by synchrotron models I now turn to spatially resolved observations of this well studied remnant. The synchrotron models make both spectral and spatial predictions, describing how the non-thermal emission varies across the remnant. Armed with spatially resolved non-thermal models and new thermal models such as VPSHOCK we can now dissect the inner workings of SN 1006.

description: Quantum repeaters have long been established to be essential for distributing entanglement over long distances. Consequently, their experimental realization constitutes a core challenge of quantum communication. However, there are numerous open questions about implementation details for realistic, near-term experimental setups. In order to assess the performance of realistic repeater protocols, we here present ReQuSim, a comprehensive Monte-Carlo based simulation platform for quantum repeaters that faithfully includes loss and models a wide range of imperfections such as memories with time-dependent noise. Our platform allows us to perform an analysis for quantum repeater setups and strategies that go far beyond known analytic results: This refers to being able to both capture more realistic noise models and analyse more complex repeater strategies. We present a number of findings centered around the combination of strategies for improving performance, such as entanglement purification and the use of multiple repeater stations, and demonstrate that there exist complex relationships between them. We stress that numerical tools such as ours are essential to model complex quantum communication protocols aimed at contributing to the quantum internet.

description: High throughput sequencing (HTS) revealed the existence of complexes of fabaviruses infecting two ‘Staccato(R) ’ sweet cherry plants (Prunus avium). Species classified as members of the genus Fabavirus are positive sense RNA viruses that possess bipartite genomes. The cherry plants Stac-3B (symptomatic) and Stac-4B (asymptomatic) were each determined to be infected with multiple RNA1 and RNA2 segments of Prunus virus F (PrVF) and the putative cherry virus F (CVF). The RNA1 and RNA2 segments Stac-3B_C3 and Stac-3B_c11, respectively, are proposed to represent an isolate identified as PrVF-CP1; while the RNA1 and RNA2 segments Stac-3B_C4 and Stac-3B_c7 are proposed to represent an isolate CVF-CC1. The termini of these four RNA segments were confirmed by RACE revealing that the first 28 nucleotides of the 5ʹuntranslated region (UTR) of all four RNA segments is conserved and is predicted to form a hairpin structure. The 3ʹUTRs possess various repeat sequences. Very interestingly, a group of PrVF sequences, exemplified by SwC 74_2c, were identified as the products of an interspecies recombination event, with PrVF 8816_s1 as a possible major parent and an isolate of CVF being the minor parent. This was supported by all methods in the RDP4 program. No association was made of any of the fabavirus complexes with any disease symptoms. This is the first description of the detection of CVF in Canada.

description: Universal Access to urban services is an indicator of equity and life quality in our cities. Culture and education services have become crucial because of their contribution to a sustainable economic and social development. This is the case, especially, for medium-sized heritage cities that struggle to survive to the conflicts derived from globalised tourism. The aim of this research is to calculate the pedestrian accessibility to the cultural and educative network of Córdoba (Spain), consisting in all the facilities of the city, in order to check the access possibilities of the whole population to them. Cartographic data collected from diverse sources have been analysed in order to define space–time areas and percentage of population living in each one of them. The results have been gathered in a set of maps (1:38,000) representing the whole urban area of the city, built and planned, as an educative and cultural entity.
$k$-Strings with exact Casimir law and Abelian-like profiles

description: We explore vortex solutions for a class of dual $SU(N)$ Yang-Mills models with $N^2-1$ Higgs fields in the adjoint representation. Initially, we show that there is a collective behavior that can be expressed in terms of a small $N$-independent number of field profiles. Then, we find a region in parameter space where the nontrivial profiles coincide with those of the Nielsen-Olesen vortex, and the energy scales exactly with the quadratic Casimir. Out of this region, we solve the ansatz equations numerically and find very small deviations from the Casimir law. The coexistence of Abelian-like string profiles and non-Abelian scaling features is welcome, as these properties have been approximately observed in pure YM lattice simulations.

Distribution of instanton sizes in a simplified instanton gas model

description: We investigate the distribution of instanton sizes in the framework of a simplified model for ensembles of instantons. This model takes into account the non-diluteness of instantons. The infrared problem for the integration over instanton sizes is dealt with in a self-consistent manner by approximating instanton interactions by a repulsive hard core potential. This leads to a dynamical suppression of large instantons. The characteristic features of the instanton size distribution are studied by means of analytic and Monte Carlo methods. In one dimension exact results can be derived. In any dimension we find a power law behaviour for small sizes, consistent with the semi-classical results. At large instanton sizes the distribution decays exponentially. The results are compared with those from lattice simulations.
