description: Current approaches in pulse detection use domain transformations so as to concentrate frequency related information that can be distinguishable from noise. In real cases we do not know when the pulse will begin, so we need a time search process in which time windows are scheduled and analysed. Each window can contain the pulsed signal (either complete or incomplete) and / or noise. In this paper a simple search process will be introduced, allowing the algorithm to process more information, upgrading the capabilities in terms of probability of detection (Pd) and probability of false alarm (Pfa).

description: The origins of X-ray and radio emissions during an X-ray binary outburst are comparatively better understood than those of ultraviolet, optical and infrared radiation. This is because multiple competing mechanisms peak in these mid-energy ranges. Ascertaining the true emission mechanism and segregating the contribution of different mechanisms, if present, is important for correct understanding of the energetics of the system and hence its geometry. We have studied the multi-wavelength spectral energy distribution of the galactic X-ray binary GRS 1716-249 ranging from near infrared (0.0005 keV) to hard X-rays (120 keV) using observations from AstroSat, Swift, and Mount Abu Infrared Observatory. Broadband spectral fitting suggests that the irradiated accretion disk dominates emission in ultraviolet and optical regimes. The near infrared emission exhibits some excess than the prediction of the irradiated disk model, which is most likely due to Synchrotron emission from jets as suggested by radio emission. Irradiation of the inner disk by the hard X-ray emission from the Corona also plays a significant role in accounting for the soft X-ray emission.

On the origin of the radial mass density profile of the Galactic halo Globular Cluster System

Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: We investigate what may be the origin of the presently observed spatial distribution of the mass of the Galactic Old Halo globular cluster system. We propose its radial mass density profile to be a relic of the distribution of the cold baryonic material in the protoGalaxy. Assuming that this one arises from the profile of the whole protoGalaxy minus the contribution of the dark matter (and a small contribution of the hot gas by which the protoglobular clouds were bound), we show that the mass distributions around the Galactic centre of this cold gas and of the Old Halo agree satisfactorily. In order to demonstrate our hypothesis even more conclusively, we simulate the evolution with time, up to an age of 15 Gyr, of a putative globular cluster system whose initial mass distribution in the Galactic halo follows the profile of the cold protogalactic gas. We show that beyond a galactocentric distance of order 2 to 3 kpc, the initial shape of such a mass density profile is preserved in spite of the complete destruction of some globular clusters and the partial evaporation of some others. This result is almost independent of the choice of the initial mass function for the globular clusters, which is still ill-determined. The shape of these evolved cluster system mass density profiles also agree with the presently observed profile of the Old Halo globular cluster system, thus strengthening our hypothesis. Our result might suggest that the flattening shown by the Old Halo mass density profile at short distance from the Galactic centre is, at least partly, of primordial origin.

description: We examine masses of hosting haloes of two photometrically-selected high-z galaxy samples: the old passively-evolving galaxies (OPEGs) and Lyman Break Galaxies (LBGs) both taken from the Subaru/XMM-Newton Deep Survey (SXDS). The large survey area of the SXDS (1sq deg) allows us to measure the angular two-point correlation functions to a wide separation of >10 arcmin with a good statistical quality. We utilize the halo model prescription for estimating characteristic masses of hosting haloes from the measured large-scale clustering amplitudes. It is found that the hosting halo mass positively correlates with the luminosity of galaxies. Then, adopting the extended Press-Schechter model (EPS), we compute the predictions for the mass evolution of the hosting haloes in the framework of the cold dark matter (CDM) cosmology in order to make an evolutionary link between the two galaxy samples at different redshifts and to identify their present-day descendants by letting their haloes evolve forward in time. It is found that, in the view of the mass evolution of hosting haloes in the CDM model, bright LBGs are consistent with being the progenitor of the OPEGs, whereas it is less likely that the LBG population, as a whole, have evolved into the OPEG population. It is also found that the present-day descendants of both the bright LBGs and OPEGs are likely to be located in massive systems such as groups of galaxies or clusters of galaxies. Finally, we estimate the hosting halo mass of local early-type galaxy samples from the 2dF and SDSS based on the halo model and it turns out that their expected characteristic mass of hosting haloes is in good agreement with the EPS predictions for the descendant's mass of both the bright LBGs and OPEGs.

description: Ethical decision‐making is a core principle in the psychology profession and ethical breaches have the potential to cause harm to clients, as well as to the profession. The present study explored the influence of experience on ethical judgements for practising psychologists when compared to psychology students. Thirty‐two psychologists and 63 students were presented with nine ethical dilemmas and asked to select one of two potential responses, with one of the responses endorsed by two experts as meeting ethical obligations of psychologists. Participants were asked to justify their decision‐making. Psychologists expressed significantly higher levels of ethical judgement on two of the nine scenarios providing limited support for the hypothesis that experience enhanced ethical decision‐making. Where differences were found justifications suggested that psychologists were more likely to consider long‐term implications and communicate stronger commitment to the professional code than did students. The findings suggest that psychologists and students largely make ethical decisions when presented with an ethical dilemma. Where differences occur these may reflect a deeper understanding of ethics and professional obligations that is developed through experience. Making ethical decision‐making a key aspect of student training and ongoing professional development for psychologists may improve ethical decision‐making.

description: We study the sensitivity of a pair of Einstein Telescopes (ET) (hypothetically located at the two sites currently under consideration for ET) to the anisotropies of the Stochastic Gravitational Wave Background (SGWB). We focus on the $\ell =0,2,4$ multipoles of an expansion of the SGWB in spherical harmonics, since the sensitivity to other multipoles is suppressed due to the fact that this pair of detector operates in a regime for which the product between the observed frequency and the distance between the two sites is much smaller than one. In this regime, the interferometer overlap functions for the anisotropic signal acquire very simple analytic expressions. These expressions can also be applied to any other pairs of interferometers (each one of arbitrary opening angle between its two arms) operating in this regime. Once the measurements at the vertices of the two sites are optimally combined, the sensitivity to the multipoles of the SGWB depends only on the latitude of the two sites, on the difference of their longitude, but not on the orientation of their arms.

Asymmetric induction in the photochemistry of 2-benzoyladamantane-2-carboxylic acid derivatives
Creators: name: Zenova, Alla Yurevna
Publisher: name: University of British Columbia
Year: 2009

description: The photochemistry of β-keto ester 28 has been studied in solution as well as the crystalline state. In both media this compound undergoes Yang photocyclization, followed by a spontaneous retro-aldol ring opening to afford δ-keto ester 42 as the major photoproduct, with both benzoyl and methoxycarbonyl groups in axial positions. [Figure.] The observed photoreactivity of β-keto ester 28 was correlated to its X-ray crystal structure. Crystallographic analysis revealed that only one γ-hydrogen in the molecule lies within a reasonable distance (2.42 A) from the ketone oxygen for abstraction to occur. The angular parameters associated with γ-hydrogen abstraction as well as the geometric .parameters associated with the reactivity of intermediate 1,4-hydroxybiradical were derived from the crystallographic data. The (-)-menthyl, (-)-bornyl and (+)-fenchyl esters of β-keto acid 36 were prepared to explore asymmetric induction by covalent chiral auxiliaries. In the solution phase photolyses of all chiral esters studied, two possible diastereomeric δ-keto esters [figure] analogous to δ-keto ester 42 were formed in unequal amounts. Low diastereoselectivity (14-28% de) in the solution phase photolyses reflected the extent of asymmetric induction due to the direct influence of the chiral auxiliary. Asymmetric induction in the solid state photolysis was studied for the (-)-bornyl and (+)-fenchyl β-keto esters. The solid state photoreaction, in which chiral information is provided by the rigid crystal environment, proceeded with high diastereoselectivity (>95% de) at quantitative conversion for the (-)-bornyl ester and with low (18% de) diastereoselectivity for (+)-fenchyl ester. The diastereoselectivity observed in the solid state was correlated with the X-ray crystal structure data for the corresponding compound. The ionic chiral auxiliary approach was also tested in the photoreaction of β-keto acid 36. Owing to its thermal instability, β-keto acid 36 was prepared in situ at low temperature and its chiral salt with optically active R-(+)-α-methylbenzylamine was obtained. The solid state photolysis of this chiral salt, followed by diazomethane work up, led to the methyl β-keto ester 42 with an excellent enantiomeric excess (>99%) at quantitative conversion of the starting material.

Subjects: subject: Education -- Research papers (Graduate)

description: This quasi-experimental pre-test/post-test design study analyzed the impact of differentiating instruction through Readers’ Theater on the reading fluency progression of second graders. Readers’ Theater was used as an engaging and motivating instructional strategy to improve the fluency for the treatment group of five students. A control group of six second grade students did not participate in the Readers’ Theater intervention. Both groups received daily, guided reading instruction. Students in the treatment group made a mean gain in their fluency of 21.6 words read per minute compared to a mean gain of 9.5 words read per minute for the control group, suggesting the Readers’ Theater intervention made a statistically significant impact on fluency. The researcher also noted that the students who participated in Readers’ Theater reported noticeable changes in perceptions of themselves as readers. Future research is suggested to further determine the utility of Readers’ Theater for differentiating instruction and improving reading skills and attitudes about reading.

description: The purpose of this study was to determine the impact of dialogue journals on student achievement in the area of reading comprehension for fourth graders. The participants of this study were fourth grade students in a Baltimore County Public School. The measurement tools for this study were the 2012-2013 Baltimore County Fourth Grade Fall and Winter Benchmark Assessments. This study used a pretest-posttest design with the Fall Benchmark being used as the pre-test and the Winter Benchmark being used as the post-test. The null hypothesis was supported for this study as there was no significant gains made by the group using the dialogue journals. Research in the area of reading comprehension interventions and effective writing strategies to help improve student achievement should continue to help provide further assistance to struggling students.

description: This study examined the impact of technology-based homework on student performance. A comparison was made using two classes of world history students; one with traditional paper and pencil homework assignments and another using technology. The purpose of this study was to examine the effect of technology-based homework on student achievement as measured by classroom exams. The null-hypothesis was that there would be no significant increase in student achievement on classroom exams because of the use of technology- based homework. Through a convenience sampling of fifty-four tenth-grade honors world history students were chosen for this study; twenty-eight in the control and twenty-six in the experimental groups. The study was done the second semester of the 2013-2014 academic school year in Baltimore County Public Schools. Using an independent t-test to examine performances of both groups on the final exam demonstrated a rejection of the null-hypothesis with a significant difference in scores [t(50)=- 2.091. p
Comparative Laboratory Evaluation and Field Observations of a Modified Class I Base

Subjects: subject: Transportation Engineering

description: A number of materials and methods have been used in the continuing search for a satisfactory initial bituminous treatment. Towards this end, three traffic bound roads were given initial treatment, in the summer of 1956, with three inches of Kentucky a Standard Class I Base mixture. The large size coarse aggregate -- either No. 36 or No. 48 stone -- in this mixture made the material difficult to work, however, and caused severe segregation during handling. Although a well integrated mixture of the type could have been compacted to about eight percent voids, the excessive segregation left many areas of the pavement very open. It was believed, therefore, that any initial treatment with this material would have to be sealed in order to prevent entry of water.

description: Eating disorders (EDs) in men are often overlooked although they are associated with similar comorbidities and health issues as found in women. The present study is an in‐depth analysis of treatment experiences of eight men who had sought help, were diagnosed with an ED and received ED‐specific treatment. Data were generated from an open‐ended interview that explored men's narratives of their experiences of an ED, as well as questions that focused on their help‐seeking behaviours and treatment experiences. Interviews were transcribed and thematically analysed. This analysis resulted in four themes. The first theme focused on how men ascribed meaning to the ED experience and how these negotiations shaped their help seeking behaviour. The second theme focused on some of the barriers and expectations of men that they encountered when negotiating treatment for an ED. The third theme encompassed the experiences of men when they received the ED‐specific treatment. The last theme included the positive outcomes of treatment and role of health professionals in treating EDs in men. The findings highlight the importance of person‐centred ED treatments for men. Also identified was a need for improved health literacy among health practitioners in the field of EDs, specifically an increased awareness of the development of tailored interventions for men.
Hyperkaehler structures and infinite-dimensional Grassmannians

description: In this paper, we describe an example of a hyperkaehler quotient of a Banach manifold by a Banach Lie group. Although the initial manifold is not diffeomorphic to a Hilbert manifold (not even to a manifold modelled on a reflexive Banach space), the quotient space obtained is a Hilbert manifold, which can furthermore be identified either with the cotangent space of a connected component of the restricted Grassmannian or with a natural complexification of this connected component, thus proving that these two manifolds are isomorphic hyperkaehler manifolds. In addition, Kaehler potentials are computed using Kostant-Souriau's theory of prequantization.

Differential Thermal Analysis of the Freeze-Thaw Mechanisms in Concrete

Subjects: subject: Transportation Engineering

description: The freezing of water in concrete may create highly disruptive internal forces, depending upon the degree of saturation of the voids and the extent of the resulting dilations. Heretofore, it has not been possible to measure the internal pressures accompanying freezing; and it is this aspect of the automatic freeze-thaw testing of concrete with which the present study was concerned. By the use of thermocouples, imbedded in concrete and referenced to an ice-water bath, it was possible to plot, on an automatic multivolt potentiometer recorder, an isothermal phase change for the absorbed water, and to demonstrate a depression of the freezing point of the water with increasing confining pressures. It was also possible, at least in a general way, to relate the progress of damage in the concrete to increased absorption and freezing point depression.
Particle-scale origins of shear strength in granular media

Publisher: name: arXiv
Year: 2008
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: The shear strength of cohesionless granular materials is generally attributed to the compactness or anisotropy of their microstructure. An open issue is how such compact or anisotropic microstructures, and thus the shear strength, depend on the particle properties. We first recall the role of fabric and force anisotropies with respect to the critical-state shear stress. Then, a model of accessible geometrical states in terms of particle connectivity and contact anisotropy is presented. This model incorporates in a simple way the fact that, due to steric exclusions, the highest levels of connectivity and anisotropy cannot be reached simultaneously, a property that affects seriously the shear strength. We also analyze the force anisotropy in the light of the specific role of weak forces in sustaining strong force chains and thus the main mechanism that underlies anisotropic force patterns. Finally, we briefly discuss the effect of interparticle friction, particle shape, size polydispersity and adhesion.

Quantum Mechanics in Non'Inertial Frames with a Multi'Temporal Quantization Scheme: I) Relativistic Particles

description: We introduce a family of relativistic non-rigid non-inertial frames as a gauge fixing of the description of N positive energy particles in the framework of parametrized Minkowski theories. Then we define a multi-temporal quantization scheme in which the particles are quantized, but not the gauge variables describing the non-inertial frames: {\it they are considered as c-number generalized times}. We study the coupled Schroedinger-like equations produced by the first class constraints and we show that there is {\it a physical scalar product independent both from time and generalized times and a unitary evolution}. Since a path in the space of the generalized times defines a non-rigid non-inertial frame, we can find the associated self-adjoint effective Hamiltonian $\hat{H}_{ni}$ for the non-inertial evolution: it differs from the inertial energy operator for the presence of inertial potentials and turns out to be {\it frame-dependent} like the energy density in general relativity. After a separation of the relativistic center of mass from the relative variables by means of a recently developed relativistic kinematics, inside $\hat{H}_{ni}$ we can identify the self-adjoint relative energy operator (the invariant mass) ${\hat{\cal M}}$ corresponding to the inertial energy and producing the same levels for the spectra of atoms as in inertial frames. Instead the (in general time-dependent) effective Hamiltonian is responsible for the interferometric effects signalling the non-inertiality of the frame but is not interpretable as an energy like in the case of time-dependent c-number external electro-magnetic fields.

We report a search for mCPs with charges $\gtrsim 10^{-4}~e$ that improves sensitivity to their abundance in matter by roughly two orders of magnitude relative to previous searches. This search is sensitive to such particles over a wide range of masses and charges for which they can form stable bound states with matter, corresponding to a gap in parameter space that is beyond the reach of previous searches from accelerators, colliders, cosmic-ray experiments, and cosmological constraints.

description: Saturation is expected to occur when a high density of partons (mainly gluons)- or equivalently strong fields in Quantum Chromodynamics (QCD) - is realized in the weak coupling regime. A way to reach saturation is through the high-energy evolution of an extended target probed at a fixed hard scale. In this case, the transition to saturation is expected to occur from nonlinear perturbative QCD dynamics. We discuss this approach to saturation, which is mathematically characterized by the appearance of traveling wave patterns in a suitable kinematical representation. A short review on traveling waves in high energy QCD and a first evidence of this phenomenon in deep-inelastic proton scattering are presented.

description: The prevalence of diseases caused by non-tuberculous mycobacteria (NTM), including M. kansasii, is increasing, necessitating further information to guide prevention, control, and treatment strategies. A comprehensive analysis of articles published until February 2023 was conducted on PubMed, Web of Science, and Scopus databases to investigate antibiotic resistance in M. kansasii species. Stata software version 17 was employed for all analyses. A total of 1647 articles were obtained through database search. After removing duplicates and unrelated studies, 17 cross-sectional studies that examined the breakpoints proposed by CLSI were included. The rates of resistance of M. kansasii to various antibiotics were as follows: clarithromycin (0%), rifampin (1%), amikacin (0%), ciprofloxacin (14%), linezolid (0%), moxifloxacin (0%), rifabutin (1%), doxycycline (96%), and SXT (49%). Our findings underscore the importance of managing and monitoring the use of these antibiotics, as well as the need for further studies to elucidate the exact mechanism of M. kansasii resistance to these antibiotics.

The new total electron energy flux particle precipitation nowcast model, a neural network called PrecipNet, takes advantage of increased expressive power afforded by ML approaches to appropriately utilize diverse information from the solar wind and geomagnetic activity and, importantly, their time histories. With a more capable representation of the organizing parameters and the target electron energy flux observations, PrecipNet achieves a >50% reduction in errors from a current state-of-the-art model oval variation, assessment, tracking, intensity, and online nowcasting (OVATION Prime), better captures the dynamic changes of the auroral flux, and provides evidence that it can capably reconstruct mesoscale phenomena. We create and apply a new framework for space weather model evaluation that culminates previous guidance from across the solar-terrestrial research community. The research approach and results are representative of the "new frontier" of space weather research at the intersection of traditional and data science-driven discovery and provides a foundation for future efforts.

description: The reform of the Common Agricultural Policy (CAP) adopted on 21 May 1992, to be implemented by 1996, anticipates some essential features of the 1994 Uruguay GATT Agreement to be implemented between 1995 and 2000. Together these two events will change substantially, and sometimes reverse, the past trends in the EU agricultural policy, and generate unprecedented changes in production, trade, as well as in producers' and consumers' welfare, creating conditions for a more timely structural adjustment. This paper will first outline the new scenario of agricultural policy in the EU in order to better devise its likely impact on the economy, namely on income distribution, on resource allocation and on the natural and social environment. A third part of the paper will focus on the perspective developments of the CAP before the beginning of the next round of multilateral negotiations in 1999, examining the possibility of a further progress of CAP reform triggered by the implementation of the GATT agreement and by a better information among European citizens of the effects of existing agricultural policies.

description: We analyze the correlation properties of the Erdos-Renyi random graph (RG) and the Barabasi-Albert scale-free network (SF) under the attack and repair strategy with detrended fluctuation analysis (DFA). The maximum degree k_max, representing the local property of the system, shows similar scaling behaviors for random graphs and scale-free networks. The fluctuations are quite random at short time scales but display strong anticorrelation at longer time scales under the same system size N and different repair probability p_re. The average degree , revealing the statistical property of the system, exhibits completely different scaling behaviors for random graphs and scale-free networks. Random graphs display long-range power-law correlations. Scale-free networks are uncorrelated at short time scales; while anticorrelated at longer time scales and the anticorrelation becoming stronger with the increase of p_re.

description: We define the affinization of an arbitrary monoidal category $\mathcal{C}$, corresponding to the category of $\mathcal{C}$-diagrams on the cylinder. We also give an alternative characterization in terms of adjoining dot generators to $\mathcal{C}$. The affinization formalizes and unifies many constructions appearing in the literature. In particular, we describe a large number of examples coming from Hecke-type algebras, braids, tangles, and knot invariants. When $\mathcal{C}$ is rigid, its affinization is isomorphic to its horizontal trace, although the two definitions look quite different. In general, the affinization and the horizontal trace are not isomorphic.

description: We compare the small-scale features visible in the Ne viii Doppler-shift map of an equatorial coronal hole (CH) as observed by SUMER with the small-scale structures of the magnetic field as constructed from a simultaneous photospheric magnetogram by a potential magnetic-field extrapolation. The combined data set is analysed with respect to the small-scale flows of coronal matter, which means that the Ne viii Doppler-shift used as tracer of the plasma flow is investigated in close connection with the ambient magnetic field. Some small closed-field regions in this largely open CH are also found in the coronal volume considered. The Doppler-shift patterns are found to be clearly linked with the field topology.

description: Large scale machine learning and deep models are extremely data-hungry. Unfortunately, obtaining large amounts of labeled data is expensive, and training state-of-the-art models (with hyperparameter tuning) requires significant computing resources and time. Secondly, real-world data is noisy and imbalanced. As a result, several recent papers try to make the training process more efficient and robust. However, most existing work either focuses on robustness or efficiency, but not both. In this work, we introduce Glister, a GeneraLIzation based data Subset selecTion for Efficient and Robust learning framework. We formulate Glister as a mixed discrete-continuous bi-level optimization problem to select a subset of the training data, which maximizes the log-likelihood on a held-out validation set. Next, we propose an iterative online algorithm Glister-Online, which performs data selection iteratively along with the parameter updates and can be applied to any loss-based learning algorithm. We then show that for a rich class of loss functions including cross-entropy, hinge-loss, squared-loss, and logistic-loss, the inner discrete data selection is an instance of (weakly) submodular optimization, and we analyze conditions for which Glister-Online reduces the validation loss and converges. Finally, we propose Glister-Active, an extension to batch active learning, and we empirically demonstrate the performance of Glister on a wide range of tasks including, (a) data selection to reduce training time, (b) robust learning under label noise and imbalance settings, and (c) batch-active learning with several deep and shallow models. We show that our framework improves upon state of the art both in efficiency and accuracy (in cases (a) and (c)) and is more efficient compared to other state-of-the-art robust learning algorithms in case (b).

description: Venetian villas, which make up one of the most typical systems of historical architectural goods in the Northern Italian countryside, are a clear example of the allocation problems of merit goods management. These problems derive from the differences between the limited financial resources available and both the actual distribution of the benefits received by the public at large and the preferences expressed by the majority. In fact, the Venetian villas are risking progressive degradation from abandonment or invasive transformations due to unsuitable management politics and scarce financial resources. For this reason, the management policies regarding these merit goods must be reexamined both theoretically and in practice. Furthermore, the legal constraints, whose purpose is to conserve the goods, must be accompanied by appropriate economic uses which offer the financial resources to conserve the goods. An exhaustive analysis of these historical architectural goods must be carried out by adopting a multidimensional approach to take into account technical, social, economic and political aspects. Therefore, a multi-criteria approach was developed in order to determine the best "feasible" compromise solution of the decision problem which policy makers have to solve. In this paper, a multiple criteria model to evaluate the aptitude of Venetian villas to sustainable economic use is illustrated. The results show that a compromise solution between sustainable economic use and conservation must be met in order to exploit the synergies between the cultural characteristics of Venetian villas and their aptitude to sustainable economic use.

description: We have detected the radio recombination lines H91-alpha and H92-alpha with rest frequencies of 8.6 GHz and 8.3 GHz from the starburst nucleus NGC 3256 at an angular resolution of 16.4" x 9.6" using the Australia Telescope Compact Array and at an angular resolution of 12.0" x 2.9" using the VLA. The line was detected at ~ 1 mJy/beam peak with a width of 160 km/s with the ATCA and at ~ 0.5 mJy/beam peak with a width of 114 km/s with the VLA. Modelling the line emitting region as a collection of HII regions, we derive constraints on the required number of HII regions, their temperature, density, and distribution. We find that a collection of 10 to 300 HII regions with temperatures of 5000 K, densities of 1000 cm^-3 to 5000 cm^-3 and diameters of 15 pc produced good matches to the line and continuum emmission. The Lyman continuum production rate required to maintain the ionization is 2 x 10^52 s^-1 to 6 x 10^53 s^-1, which requires 600 to 17000 O5 stars to be produced in the starburst.
