Beryllium in F and G Field Dwarfs from High-Resolution Canada-France-Hawaii Telescope Spectra

It is important to add observations of Be to the huge arsenal of Li observations in order to identify the mechanisms operating in stellar interiors that alter the surface composition of the light elements. Beryllium is more resistant to destruction than is Li, so information on the abundances of both Li and Be reveals more information on the internal processes than either element does alone. We have made observations of Be II at 3131 Å in 46 solar-type stars from the Canada-France-Hawaii Telescope with high spectral resolution and high signal-to-noise ratios (S/N). Our Li I 6707 Å data for 39 of these stars come from our high-resolution, high-S/N observations with the University of Hawai`i 88 inch (2.2 m) telescope and coudé spectrograph and Keck I High Resolution Echelle Spectrometer and, for six stars, from the literature. Most of the stars in our sample are F and G dwarfs with Teff between 6100 and 6600 K and with [Fe/H] between -0.6 and +0.2. The abundances of Be have been determined through spectrum synthesis, while Li has been analyzed as a blend to find the Li abundance. We find a large range in both Li and Be in these stars; for Be it is at least 2.5 dex and for Li at least 3 dex. However, there is an excellent correlation between Li and Be, as discovered by Deliyannis et al. from a smaller sample. We find that in the range of Teff of 5850 K (near the Li "peak" in open clusters) to 6680 K (at the bottom of the Li "gap" as defined by the Hyades), Li and Be appear to be depleted together. The slope of this remarkable logarithmic relation is 0.36: as Li is reduced by a factor of 10, Be is reduced by only 2.2 times. There is some scant evidence for a change in the slope between the cooler stars and the hotter stars such that the cooler stars deplete more Li relative to Be than the hotter stars. These results are well matched by models that incorporate rotationally induced slow mixing of the stellar surface material with the deeper layers of the star.
Imaging the water masers toward the H2O-PN IRAS 18061–2505

Abstract It has been suggested that the presence of disks or tori around the central stars of pre Planetary Nebulae and Planetary Nebulae is related to the collimation of the jet that are frequently observed in these sources. These disks or tori can be traced by the maser emission of some molecules such as water. In this work we present Very Large Array (VLA) observations of the water maser emission at 22 GHz toward the PN IRAS 18061–2505, for which the masers appear located on one side of the central star. For comparison with the observations, we present a simple kinematical model of a disk rotating and expanding around the central star. The model matches qualitatively the observations. However, since the masers appear only on one side of the disk, these results are not conclusive.
PHOTOMETRIC LIGHT CURVES FOR SEVEN RAPIDLY-ROTATING K DWARFS IN THE PLEIADES AND ALPHA PERSEI CLUSTERS.

Light curves and period estimates were obtained for several Pleiades and Alpha Persei cluster K dwarfs which were identified as rapid rotators in earlier spectroscopic studies. A few of the stars have previously-published light curves, making it possible to study the long-term variability of the light-curve shapes. The general cause of the photometric variability observed for these stars is an asymmetric distribution of photospheric inhomogeneities (starspots). The presence of these inhomogeneities combined with the rotation of the star lead to the light curves observed. The photometric periods derived are thus identified with the rotation period of the star, making it possible to estimate equatorial rotational velocities for these K dwarfs. These data are of particular importance because the clusters are sufficiently young that stars of this mass should have just arrived on the main sequence. These data could be used to estimate the temperatures and sizes of the spot groups necessary to produce the observed light curves for these stars.
On Degenerations and Extensions of Finite Dimensional Modules

Abstract We derive a cancellation theorem for degenerations of modules that says in particular, that projective or injective common direct summands can always be neglected. Combining the cancellation result with the existence of almost split sequences we characterize the orbit closure of a module living on preprojective components by the fact that the dimension of the homomorphism space to any other module does not decrease. For representation-directed algebras, whence in particular for path algebras of Dynkin quivers, we provide an alternative proof which shows in addition that any minimal degenerationNofMcomes from an exact sequence with middle termMwhose end terms add up toN. By a careful examination, the same is true for degenerations of matrix pencils. Having used so far the existence of certain extensions to obtain degenerations we then turn the tables and use degenerations to produce a lot of interesting short exact sequences. In particular, we show that any non-simple indecomposable over a tame quiver is an extension of an indecomposable and a simple.
Simulated annealing-based multiobjective algorithms and their application for system reliability

The paper presents five simulated annealing based multiobjective algorithms - SMOSA, UMOSA, PSA, PDMOSA and WMOSA. All of these algorithms aim to find a Pareto set of solutions of a system reliability multiobjective optimization problem in a short time. In each algorithm the solution vector explores its neighborhood in a way similar to that of Classical Simulated Annealing. All the algorithms are problem-specific and if the true Pareto-optimal set has few solutions, UMOSA, SMOSA, PSA and WMOSA work better than PDMOSA. In some cases, PSA works the best. The computational cost is least in the case of the WMOSA algorithm since it does not need to use the penalty function approach to handle the constraints, and is the maximum with PDMOSA since it requires two sets of Pareto solutions.
What is the value of real-time shipment tracking information?

Abstract This paper presents a stochastic model for evaluating the value of real-time shipment tracking information in a supply system with a manufacturer that fulfills demand from a retailer for a single product using a periodic review, order-up-to-level inventory control policy. Products shipped by the manufacturer can move through multiple stages before they reach the retailer, where each stage represents a physical location or a step in the replenishment process. The lead time for an order placed by the retailer depends on the distribution of all the shipments, or outstanding orders, across the different stages. Hence, it is desirable to track the location of shipments to determine the ordering policy that minimizes the long-run average cost for the retailer. The long-run average cost is modeled under different scenarios: with real-time tracking information, with lagged tracking information, with no tracking information and with historical information on lead times for past orders. Under optimal myopic ordering policies, it is shown that the long-run average cost for the retailer increases when the shipment tracking information is lagged. Numerical examples are used to demonstrate the savings in long-run average cost with real-time tracking information. [Supplementary materials are available for this article.

Complementarity-Aware Space Learning for Video-Text Retrieval

In general, videos are powerful at recording physical patterns (e.g., spatial layout) while texts are great at describing abstract symbols (e.g., emotion). When video and text are used in multi-modal tasks, they are claimed to be complementary and their distinct information is crucial. However, when it comes to cross-modal tasks (e.g., retrieval), existing works usually use their common part in the form of common space learning while their distinct information is abandoned. In this paper, we argue that distinct information is also beneficial for cross-modal retrieval. To address this problem, we propose a divide-and-conquer learning approach, namely Complementarity-aware Space Learning (CSL), by recasting this challenge into learning of two spaces (i.e., latent and symbolic spaces) to simultaneously explore their common and distinct information by considering multi-modal complementary character. Specifically, we first propose to learn a symbolic space from video with a memory-based video encoder and a symbolic generator. In contrast, we also introduce learning a latent space from text with a text encoder and a memory-based latent feature selector. Finally, we propose a complementarity-aware loss by integrating two spaces to facilitate video-text retrieval tasks. Extensive experiments show that our approach outperforms existing state-of-the-art methods by 5.1%, 2.1% and 0.9% of R@10 for text-to-video retrieval on three benchmarks, respectively. Ablation study also verifies that the distinct information from video and text improves the retrieval performance.

Traveling Wave Solutions to Combustion Models and Their Singular Limits

We consider the deflagration wave problem for a compressible reacting gas, with species involved in a single step chemical reaction. In the limit of small Mach numbers, the one-dimensional traveling wave problem reduces to a system of reaction-diffusion equations. Existence is proved by first considering the problem in a bounded domain, and taking an infinite domain limit. In the singular limit of high activation energy within the Arrhenius exponential reaction term, we prove strong convergence to a limiting free boundary problem; the latter is characterized by a jump of the derivatives, which we determine.
Numerical modeling of the generation of internal waves by uniform stratified flow over a thin vertical barrier

Numerical simulations of two‐dimensional stratified flow past an obstacle (thin vertical strip) were performed at relatively low Reynolds numbers. A finite differences solver was adopted to simultaneously solve Navier–Stokes equations together with transport equations for salinity (stratifying agent), and the standard Smagorinsky turbulent closure scheme was called in whenever necessary to account for turbulence. The emphases were on the evaluation of code for unsteady stratified flow applications as well as identification of transient and steady internal‐wave processes during flow past obstacles. Simulations were compared with laboratory experiments, where observations were made using a high resolution Schlieren technique and conductivity probes. Blocking was observed upstream of the obstacle, surrounded by near‐zero frequency internal waves, the phase lines of which joined those of lee waves through a transition zone in the proximity of the obstacle. This pattern was preceded by initial transients of the starting flow in which propagating internal waves played a dominant role. Confluence of isopycnals passing over/under the obstacle in the wake led to interesting flow phenomena, including the radiation of internal waves. The numerical simulations were in good agreement with observations, except that some phenomena could not be captured due to resolution issues of either numerical or experimental techniques. The efficacy of the code in point for stratified flow calculations with relevance to the atmosphere and oceans was confirmed. Copyright © 2011 John Wiley & Sons, Ltd.
Flat-Faced or Non-Flat-Faced Cats? That Is the Question

Simple Summary Despite the serious health and welfare issues related to brachycephalic breeds (e.g., pug, French bulldog, Persian, and exotic shorthair), their popularity is exponentially increasing. Brachycephalic means “shortened head” and refers to the short nose, and for this reason, the breeds with this morphological characteristic are called flat-faced breeds. The aim of this study is exploring differences in human-cat bonding, behavioural traits, perception of clinical breed-related problems, and the motivation for purchasing between brachycephalic cat owners (BCOs) and non-brachycephalic cat owners (NBCOs). This study aims to provide new knowledge on these topics, poorly explored in cats. As for owners of brachycephalic dogs, the character and appearance are the main motivations for purchasing these breeds. Most BCOs were not aware of several breed-related disorders (e.g., respiratory or ocular diseases) before acquiring their cat. Ownership of brachycephalic cat breeds results in being a complex and multidimensional phenomenon. A combination of motivations to own a brachycephalic cat and emotional engagement may explain this phenomenon. Abstract Persian and exotic shorthair cats are the most-popular brachycephalic breeds worldwide. This study aimed to explore differences in human-cat bonding, behavioural traits, perception of clinical breed-related problems, and the motivation for purchasing between brachycephalic cat owners (BCOs) and non-brachycephalic cat owners (NBCOs). Using an online questionnaire, human-cat bonding and cats’ behavioural traits were explored using the CORS and Fe-BARQ scales, respectively. Breed-related problems and motivations for purchasing were explored only in BCOs. There were 278 BCOs and 250 NBCOs who completed the survey. Respiratory diseases resulted in being the main health problem of these breeds. Most BCOs were not aware of the incidence of these disorders in brachycephalic cats. Character and appearance were the main motivations for purchasing these breeds. Perceived emotional closeness (EC), cat-owner interaction (COI), and perceived cost (PC) mean scores were significantly higher in BCOs. Playfulness and affection-/attention-seeking scores were significantly higher in NBCOs. BCOs reported a significantly higher score for separation-related behaviours. The higher scores in separation-anxiety-related behaviours and in the EC and COI scales could be related mainly to the high level of care these breeds require. The motivation for acquiring brachycephalic breeds for good companionship seems in contrast with the lower scores obtained from BCOs for playfulness and affection-/attention-seeking.
Temperature dependence of the indirect energy gap in crystalline silicon

The photoluminescence spectra of crystalline silicon samples are measured for temperatures below 1000 K. The optical transitions are analyzed in terms of excitonic and band‐to‐band transitions. From the modeling of the line shape we are able to determine the fundamental indirect band gap for temperatures up to 750 K. The temperature dependence follows the Varshni equation with Eg(0)=1.1692 eV, α=(4.9±0.2)×10−4 eV/K and β=(655±40) K.
Climate Fluctuations and Record-High Levels of Lake Michigan.

Abstract Lake Michigan reached record-high levels during 1985 and 1986 just 10 years after attaining its previous record highs of this century. The climate of the basin has become cloudier and cooler over the past 40 years, loading to decreased evaporation and transpiration, but the principal factor for the increased water in the basin is extremely heavy precipitation in the most recent 15 years. Precipitation in this 15-year period averaged 107 percent above the 90-year average, and since 1970 only two years have been dry and 10 have been classified as wet, or much above normal. No other prior period has experienced comparably wet conditions since quality basin-wide records began in 1895. The current record-high levels on Lake Michigan and all other Great Lakes are producing a mixture of impacts including advantages to shipping and hydropower generation and disadvantages to shorelines. Most of the impacts on Lake Michigan have been disastrous with beaches destroyed, shorelines eroded, mid near-shore stru.
Molecular Gas Disk in the Flocculent Spiral Galaxy NGC 4414

The central 3×6 kpc of the flocculent spiral galaxy NGC 4414 has been observed in the CO (J = 1–0) line with a 4'' (190 pc) resolution using the Nobeyama Millimeter Array. Molecular gas is found to be distributed in a relatively smooth axisymmetric disk with a central hole of 0.5–1 kpc diameter. There is no prominent spiral or bar structure or noticeable streaming motions. Several clumps of molecular gas (called “disk GMAs”) are found to be located randomly in the gas disk, with masses of a few 107 M☉ and diameters of ~ 400 pc. The molecular gas distribution agrees well with the Hα distribution imaged by Pogge, including the clumps and the central hole. The correspondence between the Hα peaks and the disk GMAs indicates that disk GMAs are the main sites of massive star formation in this flocculent galaxy. Stability analysis of the gas disk using the Toomre Q parameter shows that the gas disk is unstable but close to neutral stability everywhere except the central hole. The gas disk has a nearly constant radial Q profile owing to the radial variations of the gas surface density and the gas velocity dispersion. Masses of the observed gas clumps agree well with the predicted masses of the most unstable mode. These results suggest that the disk GMAs were formed through gravitational instability of the gas disk. It is found that two disk GMAs have too large a velocity dispersion to be gravitationally bound. They are probably dispersing at present as a result of star formation. These observational results are consistent with the scenario that the molecular gas disk in this galaxy has been maintained around neutral stability by a feedback mechanism. The steps involved in the feedback are clump formation through instability, star formation at the clumps, and clump disruption by star formation. The formation disruption cycle of a disk GMA takes several 107 yr in the center of NGC 4414.
Diffraction measurements for evaluating plastic strain in A533B ferritic steel—a feasibility study

It is known that the physical properties of many engineering materials may be strongly affected by previous loading, in particular prior plastic deformation. Most obviously, work hardening will alter subsequent yielding behaviour. Plastic deformation may also preferentially align the material microstructure, resulting in anisotropy of subsequent behaviour and a change in material fracture resistance. When physical characterization is undertaken by experimental testing it is, therefore, important to have some knowledge of the current state of the material. As a result, it is desirable to have methods of quantitatively evaluating the level of plastic deformation which specimen material may have experienced prior to testing. This paper presents the results of a feasibility study, using a ferritic reactor pressure vessel steel, into the use of diffractive methods for plastic strain evaluation. Using neutron diffraction, changes in diffraction peak width and anisotropy of peak response were correlated with plastic deformation in a tensile test. The relationships produced were then used to evaluate permanent deformation levels in large samples, representative of standard fracture toughness test specimens.
Self-Reported Beneficial Effects of Chinese Calligraphy Handwriting Training for Individuals with Mild Cognitive Impairment: An Exploratory Study

Background: Dementia is a common disease in aging populations. The treatment has mainly focused on memory decline prevention and behavior control. Nonpharmacological treatments, such as cognition training, physical exercise, and music therapy have been effective in slowing memory decline. Chinese calligraphy handwriting (CCH) through breath regulation and fine hand control involves high concentration levels, emotion regulation, and self-awareness. CCH is a mind and body activity that is culturally relevant to older Chinese adults. This study evaluated the beneficial effects of CCH on mild cognitive impairment. Methods: In 2018, we conducted 8 weeks of CCH training at the Tri-Service General Hospital. The participants were asked to copy a regular script. At the end of the course, they gave oral presentations and showed their work. Self-report questionnaires on emotion, memory, upper limb coordination, attention, and language were collected before and after training. Results: The five questionnaires showed significantly positive feelings after CCH training. The conditions of emotional stability, concentration, hand movement, memory, and speech improved. Conclusions: CCH training stimulated the brain and improved cognition, psychological symptoms, and hand stability. It is inexpensive and worthwhile for elderly Chinese individuals with mild cognitive impairment to take time daily to practice calligraphy.
