description: A sample of 145 JHK--2MASS observations of NGC open star clusters is studied, of which 132 have never been studied before. Twelve are classified as non-open clusters and 13 are re-estimated self-consistently, after applying the same methods in order to compare and calibrate our reduction procedures. The fundamental and structural parameters of the 120 new open clusters studied here are derived using color-magnitude diagrams of JHK Near-IR photometry with the fitting of solar metallicity isochrones. We provide here, for the first time, a catalog of the main parameters for these 120 open clusters, namely, diameter, distance, reddening and age.

Numerical simulations of conversion to Alfven waves in sunspots

description: We study the conversion of fast magneto-acoustic waves to Alfven waves by means of 2.5D numerical simulations in a sunspot-like magnetic configuration. A fast, essentially acoustic, wave of a given frequency and wave number is generated below the surface and propagates upward though the Alfven/acoustic equipartition layer where it splits into upgoing slow (acoustic) and fast (magnetic) waves. The fast wave quickly reflects off the steep Alfven speed gradient, but around and above this reflection height it partially converts to Alfven waves, depending on the local relative inclinations of the background magnetic field and the wavevector. To measure the efficiency of this conversion to Alfven waves we calculate acoustic and magnetic energy fluxes. The particular amplitude and phase relations between the magnetic field and velocity oscillations help us to demonstrate that the waves produced are indeed Alfven waves. We find that the conversion to Alfven waves is particularly important for strongly inclined fields like those existing in sunspot penumbrae. Equally important is the magnetic field orientation with respect to the vertical plane of wave propagation, which we refer to as "field azimuth". For field azimuth less than 90 degrees the generated Alfven waves continue upwards, but above 90 degrees downgoing Alfven waves are preferentially produced. This yields negative Alfven energy flux for azimuths between 90 and 180 degrees. Alfven energy fluxes may be comparable to or exceed acoustic fluxes, depending upon geometry, though computational exigencies limit their magnitude in our simulations.

description: High-precision spectrographs play a key role in exoplanet searches using the radial velocity technique. But at the accuracy level of 1 m.s-1, required for super-Earth characterization, stability of fiber-fed spectrograph performance is crucial considering variable observing conditions such as seeing, guiding and centering errors and, telescope vignetting. In fiber-fed spectrographs such as HARPS or SOPHIE, the fiber link scrambling properties are one of the main issues. Both the stability of the fiber near-field uniformity at the spectrograph entrance and of the far-field illumination on the echelle grating (pupil) are critical for high-precision radial velocity measurements due to the spectrograph geometrical field and aperture aberrations. We conducted tests on the SOPHIE spectrograph at the 1.93-m OHP telescope to measure the instrument sensitivity to the fiber link light feeding conditions: star decentering, telescope vignetting by the dome,and defocussing. To significantly improve on current precision, we designed a fiber link modification considering the spectrograph operational constraints. We have developed a new link which includes a piece of octagonal-section fiber, having good scrambling properties, lying inside the former circular-section fiber, and we tested the concept on a bench to characterize near-field and far-field scrambling properties. This modification has been implemented in spring 2011 on the SOPHIE spectrograph fibers and tested for the first time directly on the sky to demonstrate the gain compared to the previous fiber link. Scientific validation for exoplanet search and characterization has been conducted by observing standard stars.

Segmental and prosodic phonology and morphophonology in Tsum, a language of Nepal.
Creators: name: Liu, Naijing
Publisher: name: The Australian National University
Year: 2023

description: This thesis investigates the sound system of the underdocumented Tibeto-Burman language Tsum and ways the phonology of Tsum interacts with the linguistic domains of morphonology, syntax, and pragmatics. It showcases how grammatical and pragmatic information in Tsum are expressed through the usage of a complex sound system, based on extensive data collected during a fieldtrip in Tsum Valley and Kathmandu, Nepal, and data-checking via Zoom. This thesis first provides a comprehensive analysis of the segmental and tonal phonology of Tsum. Tsum is a typologically unique and phonologically complex language. It has seven vowels and thirty-six consonants. Tsum is a word tone language with five contrastive tones. The sound system of Tsum displays many different features although sharing many similarities with other Kyirong-Kagate languages due to the language contact. The phonology-morphology interaction is demonstrated through the investigation of phonological processes that occur with nominal morphology in Tsum. The thesis discovers that consonants and syllables can be elided during case marker attachment. Vowels undergo more complicated phonological processes, including hiatus resolution, long vowel formation, nasalization with the genitive/ergative/instrumental case marker, and vowel co-articulation with the diminutive suffix. The tonal processes associated with nominal morphology show discrepancy because some nominal markers are tonal but others are not. The interaction of phonology with syntax and semantics is illustrated with reference to two phenomena. First, vowel alternations and tonal changes in the specification of tense and aspectual meanings demonstrate that vowels and tone work independently in expressing syntactic functions. Second, a detailed examination of segmental and tonal representations and semantic meanings of consonant voicing alternations in verb pairs shows a middle-like third form characterised by a voiceless unaspirated onset and a /LH/ tone. This form suggests verb triplets rather than pairs in Tsum, unlike patterns described for related Tibeto-Burman languages. Prosodic phonology, an understudied topic among Tibeto-Burman languages, is also examined in this thesis. In the study of prosodic phonology in Tsum, examination of interrogative vs. declarative utterances reveals that the surface stem tone in the verbal complex can change depending on the intonation pattern. By analysing the Tsum language, this thesis aims to understand how to transmit grammatical and pragmatic information with a system of sounds from both segmental and tonal perspectives. Phonology, tone, and prosody bear a high functional load of coding grammatical functions and pragmatic meaning in Tsum, besides morpho-syntactic methods. It is also the case in Tsum that this information can only be revealed by examining phonology, tone, and prosody.

Principles of Distributed Data Management in 2020?

Year: 2011
Subjects: subject: Databases (cs.DB)

description: With the advents of high-speed networks, fast commodity hardware, and the web, distributed data sources have become ubiquitous. The third edition of the Özsu-Valduriez textbook Principles of Distributed Database Systems [10] reflects the evolution of distributed data management and distributed database systems. In this new edition, the fundamental principles of distributed data management could be still presented based on the three dimensions of earlier editions: distribution, heterogeneity and autonomy of the data sources. In retrospect, the focus on fundamental principles and generic techniques has been useful not only to understand and teach the material, but also to enable an infinite number of variations. The primary application of these generic techniques has been obviously for distributed and parallel DBMS versions. Today, to support the requirements of important data-intensive applications (e.g. social networks, web data analytics, scientific applications, etc.), new distributed data management techniques and systems (e.g. MapReduce, Hadoop, SciDB, Peanut, Pig latin, etc.) are emerging and receiving much attention from the research community. Although they do well in terms of consistency/flexibility/performance trade-offs for specific applications, they seem to be ad-hoc and might hurt data interoperability. The key questions I discuss are: What are the fundamental principles behind the emerging solutions? Is there any generic architectural model, to explain those principles? Do we need new foundations to look at data distribution?

description: Large-scale computer experiments are becoming increasingly important in science. A multi-step procedure is introduced to statisticians for modeling such experiments, which builds an accurate interpolator in multiple steps. In practice, the procedure shows substantial improvements in overall accuracy, but its theoretical properties are not well established. We introduce the terms nominal and numeric error and decompose the overall error of an interpolator into nominal and numeric portions. Bounds on the numeric and nominal error are developed to show theoretically that substantial gains in overall accuracy can be attained with the multi-step approach.

description: We investigate the matter rogue wave in Bose-Einstein Condensates with attractive interatomic interaction analytically and numerically. Our results show that the formation of rogue wave is mainly due to the accumulation of energy and atoms toward to its central part; Rogue wave is unstable and the decay rate of the atomic number can be effectively controlled by modulating the trapping frequency of external potential. The numerical simulation demonstrate that even a small periodic perturbation with small modulation frequency can induce the generation of a near-ideal matter rogue wave. We also give an experimental protocol to observe this phenomenon in Bose-Einstein Condensates.

description: A software architecture describes the structure of a computing system by specifying software components and their interactions. Mapping a software architecture to an implementation is a well known challenge. A key element of this mapping is the architecture's description of the data and control-flow interactions between components. The characterization of these interactions can be rather abstract or very concrete, providing more or less implementation guidance, programming support, and static verification. In this paper, we explore one point in the design space between abstract and concrete component interaction specifications. We introduce a notion of behavioral contract that expresses the set of allowed interactions between components, describing both data and control-flow constraints. This declaration is part of the architecture description, allows generation of extensive programming support, and enables various verifications. We instantiate our approach in an architecture description language for the domain of Sense/Compute/Control applications, and describe associated compilation and verification strategies.

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Monte Carlo simulations using entropic sampling to estimate the number of configurations of a given energy are a valuable alternative to traditional methods. We introduce {\it tomographic} entropic sampling, a scheme which uses multiple studies, starting from different regions of configuration space, to yield precise estimates of the number of configurations over the {\it full range} of energies, {\it without} dividing the latter into subsets or windows. Applied to the Ising model on the square lattice, the method yields the critical temperature to an accuracy of about 0.01%, and critical exponents to 1% or better. Predictions for systems sizes L=10 - 160, for the temperature of the specific heat maximum, and of the specific heat at the critical temperature, are in very close agreement with exact results. For the Ising model on the simple cubic lattice the critical temperature is given to within 0.003% of the best available estimate; the exponent ratios $β/ν$ and $γ/ν$ are given to within about 0.4% and 1%, respectively, of the literature values. In both two and three dimensions, results for the {\it antiferromagnetic} critical point are fully consistent with those of the ferromagnetic transition. Application to the lattice gas with nearest-neighbor exclusion on the square lattice again yields the critical chemical potential and exponent ratios $β/ν$ and $γ/ν$ to good precision.

description: We investigate the dependence of occurrence of bars in galaxies on galaxy properties and environment. We use a volume-limited sample of 33,391 galaxies brighter than $M_{r}=-19.5+5$log$h$ at $0.02\le z\le0.05489$, drawn from the SDSS DR 7. We classify the galaxies into early and late types, and identify bars by visual inspection. Among 10,674 late-type galaxies with axis ratio $b/a>0.60$, we find 3,240 barred galaxies ($f_{bar}=30.4%$) which divide into 2,542 strong bars ($f_{SB1}=23.8%$) and 698 weak bars ($f_{SB2}=6.5%$). We find that $f_{SB1}$ increases as $u-r$ color becomes redder, and that it has a maximum value at intermediate velocity dispersion ($σ\simeq$150 km s$^{-1}$). This trend suggests that strong bars are dominantly hosted by intermediate-mass systems. Weak bars prefer bluer galaxies with lower mass and lower concentration. In the case of strong bars, their dependence on the concentration index appears only for massive galaxies with $σ>150$ km s$^{-1}$. We also find that $f_{bar}$ does not directly depend on the large-scale background density when other physical parameters ($u-r$ color or $σ$) are fixed. We discover that $f_{SB1}$ decreases as the separation to the nearest neighbor galaxy becomes smaller than 0.1 times the virial radius of the neighbor regardless of neighbor's morphology. These results imply that strong bars are likely to be destroyed during strong tidal interactions, and that the mechanism for this phenomenon is gravitational and not hydrodynamical. The fraction of weak bars has no correlation with environmental parameters. We do not find any direct evidence for environmental stimulation of bar formation.

description: During summer 2014, we observed bleaching among many coral species in the upper Florida Keys. As water temperatures continued to rise, increasing numbers of coral species were observed with bleached tissue. In mid to late August, we observed bleaching affecting acroporid corals (Fig. 1) at various sites. Based on these informal observations, we undertook additional surveys of our 7 existing Acropora palmata monitoring sites (Fig. 2). This report describes the nature of the bleaching event along with preliminary data on the progression and impact of this event on the A. palmata at these sites. While the Florida Keys reefs have experienced moderate bleaching events in the past decade, this is the first bleaching event to affect local A. palmata since the 1998 El Niño-associated bleaching event (Miller et al. 2002). The only other extensive description of bleaching affecting A. palmata is from the US Virgin Islands during the Caribbean wide thermal bleaching event in 2005.

description: Tympanoplasty surgery, which entails the reconstruction of the middle ear hearing apparatus, arose from the basic methods of eardrum repair known as myringoplasty. Reconstructive surgery of the conductive hearing mechanism is collectively called as tympanoplasty, which has gradually evolved over time with the contributions from all over the word. aim of the present historical review is to summarize the Indian contributions in the development of the technique of tympanoplasty literature review was conducted using only the “Medline” search using keywords “tympanoplasty” and “ossiculoplasty” in “India” on 15th June 2016. A total of 195 articles and abstracts were found dated from the year 1998 onwards. Articles describing work on technique were included, and those describing only experimentation with graft material were excluded. All articles were fully read and analysed. It was found that there had been experiments regarding the choice of anaesthesia and the use of combinations of different chemical agents for this purpose. There were suggestions in favour of monitored anaesthesia care for the surgery in select patients. Surgeons expressed their perspectives on the time and conditions for the surgery, laterality of surgery, different types of incisions, use of endoscopes, graft placement techniques, ossicular replacements with autologous or allogenic grafts, and the timing of prophylactic antibiotic therapy given after or during the surgery. The range of work is wide and covers most of the aspects of surgery; however, the incorporation of a uniform methodology and standards reporting results were lacking in the articles reviewed. It is recommended that common guidelines for reporting results of tympanoplasty be framed for the Indian sub-continent as a whole. Such an effort will promote uniform reporting standards and hence will become a stable step stone for future analysis and research in the middle ear reconstruction.

When reduced to four dimensions in Kaluza-Klein theory, these solutions describe (possibly rotating) electrically charged black holes in superposition with a finitely separated magnetic monopole. Various properties of these solutions are studied, from both a five- and four-dimensional perspective.

description: Relativistic energy density functionals (REDF) provide a complete and accurate, global description of nuclear structure phenomena. A modern semi-empirical functional, adjusted to the nuclear matter equation of state and to empirical masses of deformed nuclei, is applied to studies of shapes of superheavy nuclei. The theoretical framework is tested in a comparison of calculated masses, quadrupole deformations, and potential energy barriers to available data on actinide isotopes. Self-consistent mean-field calculations predict a variety of spherical, axial and triaxial shapes of long-lived superheavy nuclei, and their alpha-decay energies and half-lives are compared to data. A microscopic, REDF-based, quadrupole collective Hamiltonian model is used to study the effect of explicit treatment of collective correlations in the calculation of Qα values and half-lives.

description: In contrast to the Pb-based magnetoelectric laminates (MELs), we find in the BaTiO3 and NiFe2O4 laminates (number of layers n = 5-25) that the longitudinal magnetoelectric (ME) voltage coefficient Alpha E33 becomes much larger than the transverse one due to preferential alignment of magnetic moments along the NiFe2O4 plane. Moreover, upon decreasing each layer thickness down to 15 um, we realize enhanced Alpha E33 up to 18 mV/ (cm Oe) and systematic increase of the ME sensitivity in proportion to n to achieve the largest in the Pb-free MELs (400*10^-6V/Oe), thereby providing pathways for tailoring ME coupling in mass-produced, environment friendly laminates.

The distribution of metals in hot DA white dwarfs

description: The importance to stellar evolution of understanding the metal abundances in hot white dwarfs is well known. Previous work has found the hot DA white dwarfs REJ 1032+532, REJ 1614-085 and GD 659 to have highly abundant, stratified photospheric nitrogen, due to the narrow absorption line profiles of the FUV N V doublet and the lack of EUV continuum absorption. A preliminary analysis of the extremely narrow, deep line profiles of the photospheric metal absorption features of PG 0948+534 suggested a similar photospheric metal configuration. However, other studies have found REJ 1032+532, REJ 1614-085 and GD 659 can be well described by homogeneous models, with nitrogen abundances more in keeping with those of white dwarfs with higher effective temperatures. Here, a re-analysis of the nitrogen absorption features seen in REJ 1032+532, REJ 1614-085 and GD 659 is presented, with the aim of better understanding the structure of these stars, to test which models better represent the observed data and apply the results to the line profiles seen in PG 0948+534. A degeneracy is seen in the modelling of the nitrogen absorption line profiles of REJ 1032+532, REJ 1614-085 and GD 659, with low abundance, homogeneously distributed nitrogen models most likely being a better representation of the observed data. In PG 0948+534, no such degeneracy is seen, and the enigmatically deep line profiles could not be modelled satisfactorially.

description: Being able to measure each merger's sky location, distance, component masses, and conceivably spins, ground-based gravitational-wave detectors will provide a extensive and detailed sample of coalescing compact binaries (CCBs) in the local and, with third-generation detectors, distant universe. These measurements will distinguish between competing progenitor formation models. In this paper we develop practical tools to characterize the amount of experimentally accessible information available, to distinguish between two a priori progenitor models. Using a simple time-independent model, we demonstrate the information content scales strongly with the number of observations. The exact scaling depends on how significantly mass distributions change between similar models. We develop phenomenological diagnostics to estimate how many models can be distinguished, using first-generation and future instruments. Finally, we emphasize that multi-observable distributions can be fully exploited only with very precisely calibrated detectors, search pipelines, parameter estimation, and Bayesian model inference.

Purge System

description: We present the design of a compact purge system designed for the TeraSmart terahertz spectrometer offered by Menlo Systems, but compatible with other spectrometers based on fiber coupled photoconductive antennas. While connected to the nitrogen (or dry air) source, the system effectively deals with water vapor absorption that is a well-known issue in terahertz spectroscopy limiting a signal-to-noise ratio. The system was designed for the lens-based version of the TeraSmart spectrometer arranged in a linear configuration for transmission measurements. However, the underlying idea can also be adapted to a reflection configuration or a mirror-based spectrometer with off-axis parabolic mirrors mounted in a cage system.

description: Using high-quality, broad-band afterglow data for GRB 091127, we investigate the validity of the synchrotron fireball model for gamma-ray bursts, and infer physical parameters of the ultra-relativistic outflow. We used multi-wavelength follow-up observations obtained with GROND and the XRT onboard the Swift satellite. The resulting afterglow light curve is of excellent accuracy, and the spectral energy distribution is well-sampled over 5 decades in energy. These data present one of the most comprehensive observing campaigns for a single GRB afterglow and allow us to test several proposed emission models and outflow characteristics in unprecedented detail. Both the multi-color light curve and the broad-band SED of the afterglow of GRB 091127 show evidence of a cooling break moving from high to lower energies. The early light curve is well described by a broken power-law, where the initial decay in the optical/NIR wavelength range is considerably flatter than at X-rays. Detailed fitting of the time-resolved SED shows that the break is very smooth with a sharpness index of 2.2 +- 0.2, and evolves towards lower frequencies as a power-law with index -1.23 +- 0.06. These are the first accurate and contemporaneous measurements of both the sharpness of the spectral break and its time evolution. The measured evolution of the cooling break (nu_c propto t^-1.2) is not consistent with the predictions of the standard model, wherein nu_c propto t^-0.5 is expected. A possible explanation for the observed behavior is a time dependence of the microphysical parameters, in particular the fraction of the total energy in the magnetic field epsilon_B. This conclusion provides further evidence that the standard fireball model is too simplistic, and time-dependent micro-physical parameters may be required to model the growing number of well-sampled afterglow light curves.

description: We study dynamics of the interaction between two weak light beams mediated by a strongly coupled quantum dot-photonic crystal cavity system. First, we perform all optical switching of a weak continuous-wave signal with a pulsed control beam, and then perform switching between two pulsed beams (40ps pulses) at the single photon level. Our results show that the quantum dot-nanocavity system creates strong, controllable interactions at the single photon level.
