description: The thermodynamic and radiative properties of TiO in the local thermodynamic equilibrium (LTE) and non-LTE (NLTE) were investigated. Firstly, we investigated the potential energy curves of fifteen electronic states of TiO by the icMRCI + Q method with a large aug-cc-pwCV5Z-DK basis set. Then the internal partition functions, average internal energies, specific heats at temperatures from 100 to 15,000 K in the LTE and NLTE were obtained. The contributions of different states are not affected by the condition of the gas. In addition, the transition dipole moments for eight transitions and the radiative properties (absorption and emissivity) of TiO in the LTE and NLTE were obtained. The A3Φ−X3Δ, B3Π−X3Δ and C3Δ−X3Δ transitions play a key role in the calculations of the absorption and emissivity. The absorption and emissivity in the LTE and NLTE were also calculated, and the electronic and vibrational energy highly contributes to the absorption and the translational and rotational energy highly contributes to the emissivity.

description: Transit observations have found the majority of exoplanets to date. Spectroscopic observations of transits and eclipses are the most commonly used tool to characterize exoplanet atmospheres and will be used in the search for life. However, an exoplanet's orbit must be aligned with our line of sight to observe a transit. Here we ask, from which stellar vantage points would a distant observer be able to search for life on Earth in the same way? We use the TESS Input Catalog and data from Gaia DR2 to identify the closest stars that could see Earth as a transiting exoplanet: We identify 1,004 Main Sequence stars within 100 parsecs, of which 508 guarantee a minimum 10-hour long observation of Earth's transit. Our star list consists of about 77% M-type, 12% K-type, 6% G-type, 4% F-type stars, and 1% A-type stars close to the ecliptic. SETI searches like the Breakthrough Listen Initiative are already focusing on this part of the sky. Our catalog now provides a target list for this search. As part of the extended mission, NASA's TESS will also search for transiting planets in the ecliptic to find planets that could detect life on our transiting Earth as well.

description: The task object tracking is vital in numerous applications such as autonomous driving, intelligent surveillance, robotics, etc. This task entails the assigning of a bounding box to an object in a video stream, given only the bounding box for that object on the first frame. In 2015, a new type of video object tracking (VOT) dataset was created that introduced rotated bounding boxes as an extension of axis-aligned ones. In this work, we introduce a novel end-to-end deep learning method based on the Transformer Multi-Head Attention architecture. We also present a new type of loss function, which takes into account the bounding box overlap and orientation. Our Deep Object Tracking model with Circular Loss Function (DOTCL) shows an considerable improvement in terms of robustness over current state-of-the-art end-to-end deep learning models. It also outperforms state-of-the-art object tracking methods on VOT2018 dataset in terms of expected average overlap (EAO) metric.

description: We investigate the effect of the turbulent power spectrum (P(k) \propto k^{-n}, with n=3, 4 or 5) on the fragmentation of low-mass cores, by means of SPH simulations. We adopt initial density profiles and low levels of turbulence based on observation, and for each n-value we conduct an ensemble of simulations with different initial seeds for the turbulent velocity field, so as to obtain reasonable statistics. We find that when power is concentrated at larger scales (i.e. for larger n), more protostellar objects form and there is a higher proportion of low-mass stars and brown dwarfs. This is in direct contrast with the recent results of Delgado Donate et al., presumably because they adopted much higher levels of turbulence.

The effects of convective clouds on vertical scalar transport using a numerically simulated flow field

In the planetary boundary layer (PBL) (loosely defined as the layer < 1 km above the surface), pollutants travel shorter distances and have shorter residence times relative to those in the upper troposphere. Without clouds, the pollutants released near the surface are likely to stay within the PBL (i.e., the smog layer) or deposit onto the ground if there is no deep convection to carry them upward. The objective of this study was to understand how deep convective cloud systems influence the transport of insoluble species to the upper troposphere using a Lagrangian approach. We used velocity field data from a synthetic flow field numerically generated from a 3-D large eddy simulation (LES) model of a deep convection system over a tropical ocean at a time interval of 15 minutes to drive the particles. The domain was large, consisting of 2048 x 2048 x 256 (or 10⁹) grid points, so this LES is also known as a giga-LES. The results showed three interesting features: First, a peak in the particle concentration occurred around 8-9 km at 3, 6, and 12 hours after their release, which is a couple of km’s below the anvil located at 12 km. Possible mechanisms explaining this include water loading and a larger areal coverage of downward motion than upward motion (i.e., a positively skewed vertical velocity field) at that height. Second, approximately 25% of particles remained near the surface (at z = 25 m), the lowest level used for the particles. This is probably due to neglecting small-scale turbulence (or subgrid-scale (SGS) motion) in our Lagrangian approach. Finally, within the PBL, we expected to see a homogenous distribution of particles due to the turbulence near the surface, but instead we found a sharp drop in the PBL. Possible explanations include (1) neglecting the SGS effect and (2) the use of a large time interval of the velocity field, 15 minutes in this study for following the particles. Our future work will include the SGS effect, and will use a 5-minute time interval of the flow field.

description: The auditory system of humanoid robots has gained increased attention in recent years. This system typically acquires the surrounding sound field by means of a microphone array. Signals acquired by the array are then processed using various methods. One of the widely applied methods is direction of arrival estimation. The conventional direction of arrival estimation methods assume that the array is fixed at a given position during the estimation. However, this is not necessarily true for an array installed on a moving humanoid robot. The array motion, if not accounted for appropriately, can introduce a significant error in the estimated direction of arrival. The current paper presents a signal model that takes the motion into account. Based on this model, two processing methods are proposed. The first one compensates for the motion of the robot. The second method is applicable to periodic signals and utilizes the motion in order to enhance the performance to a level beyond that of a stationary array. Numerical simulations and an experimental study are provided, demonstrating that the motion compensation method almost eliminates the motion-related error. It is also demonstrated that by using the motion-based enhancement method it is possible to improve the direction of arrival estimation performance, as compared to that obtained when using a stationary array.

Patients’ and families’ perceptions of factors that affect recovery from cadiac disease : a rural community perspective

Year: 2009

description: This study used focus groups as a research method to elicit cardiac patients' and families' perspectives of the factors that affect recovery from cardiac disease in a rural community. The purpose of studying these perceptions was to gain an understanding of the behavioral characteristics, environmental indicators and educational factors that affect their recovery from heart disease. It was proposed that the behavioral and environmental forces and educational factors impacting on the cardiac patients' health and recovery needed to be understood before patients could be encouraged to participate actively in decision making that affects their health. A health promotion model was used as a conceptual framework. Eight males and three females participated in one of two focus groups and three males and one female were interviewed individually as key informants. The ages of the participants ranged from 45 to 79 years. From analysis of the data, themes were identified and significant statements were used to describe the phenomenon under study. The findings of this study suggest that although in-hospital cardiac education programs can provide general information to patients and families, there is a need to give specific information regarding the first few weeks at home and to provide early home support by health care professionals to reinforce this information and to provide emotional support. Knowledge of the available resources in the rural community is essential. A group setting for educational, psychosocial and physical exercise is beneficial. However, families and physicians need to be educated to the benefits of these programs. Alternative resources may be required for people who cannot or will not attend these groups.

description: At the end of 2018, 200 ethanol refineries were operating in the U.S. and processing nearly 40 percent of U.S. corn production. These refineries are widely dispersed and the typical ethanol refining firm operates several plants. Hedging is widely used as a price risk management strategy. The dispersion of a given firm’s plants leads us to ask the question posed by the title of this paper – should the plant’s location be considered in constructing a hedging program? We tested this notion by drawing a sample from the plants operated by a multi-state/multi-plant ethanol refiner. We interviewed plant managers to get information about input-output coefficients, inventory turnover, plant efficiency comparisons, and hedging horizons. This information informed our modelling. To test our premise, we sought plant location prices for corn, natural gas, ethanol, dried distiller gran, and distiller corn oil. Local corn prices were obtained but we had to use proxies and state averages for the other prices. Standard hedging methodology was applied as we examined two hedging strategies: (a) hedging the crush margin, and (b) hedging individual commodity transactions then combining these hedges according to the input-output coefficients to hedge the crushing margin. Approach (b) produced better results but the data limitations hindered testing our main hypothesis. In addition to variations in hedge ratios for each location, we also discovered that (a) storage periods for input and output inventories are short (1 to 2 weeks), (b) input-output coefficient variability across plants creates opportunities for location specific hedging strategies, and (c) previous studies that are based on aggregated cash prices likely overstate the effectiveness of local hedging strategies.

description: The Kentucky Transportation Cabinet (KYTC) conducted an experimental project to investigate the use of accelerated maintenance painting on several overpass and elevated steel structures (74,000 ft2) in Louisville. Accelerated maintenance painting procedures specified for this project entailed limited access for the painting contractor coupled with incentives/disincentives to complete each phase of the work involving traffic closures on the underlying roadways. The approach was coupled with the use of abrasive blasting for surface preparation and the application of a rapid-cure 2-coat paint system to facilitate the work.  The project was let for $402,800. The contractor proceeded to paint 4 spans designated for convention painting (no access time limitations or incentives/disincentives). Three spans were designated for accelerated maintenance paint. Those were divided into 6 control areas with between 4,000 to 6,000 ft2 of steel to be painted. The contractor was allotted 9 to 12 hours to paint those areas on separate days. During the accelerated maintenance painting, the contractor experienced several time overruns and problems with blistering coatings on several spans. The latter was due to primarily to excessive coating thicknesses. A portion of the work was completed properly validating the technical approach employed. The accelerated maintenance painting portion of the work is described in detail. Recommendations are provided for implementing future accelerated maintenance painting projects.

description: Social media has shaken the foundations of our society, unlikely as it may seem. Many of the popular tools used to moderate harmful digital content, however, have received widespread criticism from both the academic community and the public sphere for middling performance and lack of accountability. Though social media research is thought to center primarily on natural language processing, we demonstrate the need for the community to understand multimedia processing and its unique ethical considerations. Specifically, we identify statistical differences in the performance of Amazon Turk (MTurk) annotators when different modalities of information are provided and discuss the patterns of harm that arise from crowd-sourced human demographic prediction. Finally, we discuss the consequences of those biases through auditing the performance of a toxicity detector called Perspective API on the language of Twitter users across a variety of demographic categories.

description: This paper deals with the vibration analysis of an asymmetric composite beam composed of glass a piezoelectric material. The Bernoulli's beam theory is adopted for mechanical deformations, and the electric potential field of the piezoelectric material is assumed such that the divergence-free requirement of the electrical displacements is satisfied. The accuracy of the analytic model is assessed by comparing the resonance frequencies obtained by the analytic model with those obtained by the finite element method. The model developed can be used as a tool for designing piezoelectric actuators such as micro-pumps.

description: A study on the interaction of a fourth-generation antibiotic drug, moxifloxacin hydrochloride (MFH), with a cationic surfactant, such as cetyltrimethylammonium bromide (CTAB) in the aqueous solution of alcohol (1-propanol (1-PrOH)) and polyols (galactose/maltose), has been carried out using the conductivity measurement technique. The critical micelle concentration (cmc), micelle ionisation (α), counter ion binding (β), and thermodynamic properties (ΔGm0, ΔHm0, and ΔSm0) for the self-aggregation of MFH + CTAB mixture have been estimated in 1-PrOH/polyols solutions. The presence of 1-PrOH delays the MFH + CTAB micelle formation, whereas polyols create a congenial environment for the micelle formation. In 1-PrOH, the values of α experience a reduction with the increase of 1-PrOH concentration and temperature. The values of α were found to be dependent on the concentration of other additives. In all of the cases thoroughly studied, the values of ΔGm0 were found negative, which experience an enhancement in polyols solutions and decreased in 1-PrOH solution. On the basis of ΔHm0 and ΔSm0 values, the suggested interaction forces between MFH and surfactant are hydrophobic, ion-dipole, and electrostatic in nature. The values of ΔHm0,∗ reveal that the micelle is more stable in polyols media than that of the 1-PrOH medium.

description: We present a new method of calculating the distribution function and fluctuations for a Bose-Einstein condensate (BEC) of N interacting atoms. The present formulation combines our previous master equation and canonical ensemble quasiparticle techniques. It is applicable both for ideal and interacting Bogoliubov BEC and yields remarkable accuracy at all temperatures. For the interacting gas of 200 bosons in a box we plot the temperature dependence of the first four central moments of the condensate particle number and compare the results with the ideal gas. For the interacting mesoscopic BEC, as with the ideal gas, we find a smooth transition for the condensate particle number as we pass through the critical temperature.

Mitigating potential disasters from land-falling tropical cyclones requires accurate forecasts of trajectory and intensity. In the last 20 years, trajectory forecasting has improved 50%, while intensity forecasts have improved little or not at all. This lack of any major advances can be partly explained by poor understanding of the physical processes behind intensity changes. Few recent studies suggest that monitoring lightning activity in tropical cyclones could help improve understanding of these processes and also help predict intensification. We studied lightning in six Atlantic tropical cyclones using the Long-Range Lightning Detection Network, which reaches 2,000 kilometers offshore of the continental U.S. With exception of tropical cyclones intensifying close to continental landfall, lightning frequency didnât show a consistent peak before the time of maximum sustained winds. On the other hand, the outer rainband-to-eyewall lightning ratio shows a clear peak 24 hours before maximum sustained winds in all of the storms. A better understanding of the physics behind the temporal behavior of the ratio is needed. Preliminary assessment of these results suggests that some lightning changes could be related to the eyewall replacement cycle. Interaction of tropical cyclones with continents could increase lightning activity and the use of a ratio is not needed to see a clear peak in lightning before maximum sustained winds. A more detailed approach about the interactions between the outer rainband and eyewall lightning activity should be conducted. Lightning in the eyewall should be compared with radar and airplane observations to observe its relationship with the eyewall replacement cycles.

description: Domain wall motion along ferrimagnets is evaluated using micromagnetic simulations and a collective-coordinates model, both considering two sublattices with independent parameters. Analytical expressions are derived for strips on top of either a heavy metal or a substrate with negligible interfacial Dzyaloshinskii-Moriya Interaction. The work focuses its findings in this latter case, with a field-driven domain wall motion depicting precessional dynamics which become rigid at the angular momentum compensation temperature, and a current-driven dynamics presenting more complex behavior, depending on the polarization factors for each sublattice. Importantly, our analyses provide also novel interpretation of recent evidence on current-driven domain wall motion, where walls move either along or against the current depending on temperature. Besides, our approach is able to substantiate the large non-adiabatic effective parameters found for these systems.

description: Using 65 million $Υ(4S)\to B\bar{B}$ events collected with the BABAR detector at the PEP-II $e^{+}e^{-}$ storage ring at the Stanford Linear Accelerator Center, we measure the color-favored branching fractions ${\cal B}(\bar{B^{0}} \to D^{+} π^{-}) = (2.55 \pm 0.05 \pm 0.16)\times 10^{-3}$, ${\cal B}(\bar{B^{0}} \to D^{*+} π^{-}) = (2.79 \pm 0.08 \pm 0.17)\times 10^{-3}$, ${\cal B}(B^{-} \to D^{0} π^{-}) = (4.90 \pm 0.07 \pm 0.22)\times 10^{-3}$ and ${\cal B}(B^{-} \to D^{*0} π^{-}) = (5.52 \pm 0.17 \pm 0.42)\times 10^{-3}$, where the first error is statistical and the second is systematic. With these results and the current world average for the branching fraction for the color-suppressed decay $\bar{B^{0}} \to D^{(*)0}π^{0}$, the cosines of the strong phase difference $δ$ between the $I=1/2$ and $I=3/2$ isospin amplitudes are determined to be $ \cos δ= 0.872^{+0.008+0.031}_{-0.007-0.029}$ for the $\bar{B} \to Dπ$ process and $ \cos δ= 0.924^{+0.019+0.063}_{-0.017-0.054}$ for the $\bar{B} \to D^{*}π$ process. Under the isospin symmetry, the results for $\cos δ$ suggest that final-state interactions are present in the $Dπ$ system.

Tropical cyclone (TC) intensity forecasts continue to be one of the most challenging aspects of hurricane prediction. However, through an innovative new tracking and analysis tool, a high resolution, real-time analysis and greater understanding of the complex dynamics of TCs is possible, both leading to better forecasting skill. The validity of this tool was analyzed in this research. Through the ground-based Velocity Track Display (GBVTD) technique, a single ground-based Doppler radar data can be used to retrieve the three-dimensional (3-D) kinematic structure of a TC. The GBVTD technique and GBVTD-simplex center finding algorithm formed the basis of the Vortex Objective Radar Tracking and Circulation (VORTRAC) software package for this purpose. VORTRAC is capable of automatic center tracking and retrieval of storm-scale circulation, structure, and central pressure tendency of a TC, for use in real-time forecasting and research. VORTRAC was utilized herein to analyze Hurricane Danny (1997). This analysis was then compared to the National Hurricane Center (NHC) best track (considered to be the "ground truth") and the manual GBVTD analysis previously performed on Danny. Additionally, the VORTRAC runs from two separate radars were compared. The VORTRAC software package was shown to be a viable tool for the retrieval of the detailed 3-D structure of a TC. VORTRAC was shown to agree well with observations and with manual GBVTD analyses, while efficiently processing data at a high temporal resolution. This promises to be a useful tool for both forecasting and research.

description: The Konya Closed Basin (KCB) in Turkey has a cold semiarid to warm Mediterranean climate and hosts the largest Turkish freshwater lake, Lake Beyşehir, and the iconic saline Lake Tuz. Using published as well as our own ground-truth and remote sensing data, we provide (1) a brief description of the paleoenvironmental changes in the KCB; followed by (2) a detailed description of the changes in land use, crop farming, groundwater and surface water levels, and climate; and (3) associated changes in lake water surface area and salinity as well as in waterbird and fish communities during the past 40 years. The KCB is intensively farmed, and the farming of mainly water intensive crops has increased substantially, especially since 2000. This, combined with climate warming, has led to a substantial rate of reduction of the groundwater level (up to 1 m/yr) and the surface area of the lakes and wetlands, followed by an increase in salinisation, and even complete loss of several wetlands. Three globally threatened waterbird species face extinction in the basin, and 18 of the 62 previous breeding species have already been lost. The KCB has 38 fish species, of which 74% are endemic and 61% are considered threatened or near threatened. Modelling projections using various climate and land use scenarios predict serious additional reductions of the water level in the future due to climate change, leading to deterioration (or complete loss) of lake ecosystems and the services they provide.

description: We report the discovery of two-phase unconventional superconductivity in CeRh$_2$As$_2$. Using thermodynamic probes, we establish that the superconducting critical field of its high-field phase is as high as 14 T, remarkable in a material whose transition temperature is 0.26 K. Furthermore, a $c$-axis field drives a transition between two different superconducting phases. In spite of the fact that CeRh$_2$As$_2$ is globally centrosymmetric, we show that local inversion-symmetry breaking at the Ce sites enables Rashba spin-orbit coupling to play a key role in the underlying physics. More detailed analysis identifies the transition from the low- to high-field states to be associated with one between states of even and odd parity.

description: The morphology of the total gas and the neutral hydrogen (H I) distributions during the cosmological epoch of reionization can be quantified with Minkowski Functionals (MFs) of isodensity surfaces. We compute the MFs from the output of a high-resolution numerical simulation which includes explicit treatment of transfer of UV ionizing radiation. "Galaxies" identified in the simulation using semi-analytic models of galaxy formation are assumed to be the sole sources of UV photons. The MFs of the total gas distribution are well described by the analytic expressions derived for lognormal random fields. The statistical properties of the diffuse H I depend on the gas distribution and on the way ionized regions propagate in the inter-galactic medium (IGM). The deviations of the MFs of the H I distribution from those of a lognormal random field are, therefore, caused by reionization. We use the MFs to discriminate between the various stages of reionization in the simulation. We suggest a simple model of reionization which reproduces the MFs derived from this simulation. Using random realizations of lognormal density fields, we also assess the ability of MFs to distinguish between different reionization scenarios. Our results are relevant to the analysis of future cosmological twenty-one centimeter maps.

description: In this work, we present the study of the stationary structures and the breathing mode behavior of a two-dimensional self-bound binary Bose droplet. We employ an analytical approach using a variational ansatz with a super-Gaussian trial order parameter and compare it with the numerical solutions of the extended Gross-Pitaevskii equation. We find that the super-Gaussian is superior to the often used Gaussian ansatz in describing the stationary and dynamical properties of the system. We find that for sufficiently large non-rotating droplets the breathing mode is energetically favourable compared to the self-evaporating process. For small self-bound systems our results differ based on the ansatz. Inducing angular momentum by imprinting multiply quantized vortices at the droplet center, this preference for the breathing mode persists independent of the norm.

The mechanism of malignancy associated changes

Publisher: name: University of British Columbia

description: Malignancy Associated Changes (MAC) can be defined as subtle morphologic and or physiologic changes which occur in ostensibly normal cells of patients harboring malignant or pre-malignant lesions. This phenomenon has been postulated to have great potential as a powerful tool in the fight against cancer. Recent evidence indicates that this phenomenon can be used in the detection of cancers in their earliest stages, for the objective diagnosis and prognosis of these cancers, as well as a means for monitoring of treatment outcome. Yet the mechanism of MAC remains poorly understood. There have been two main theories proposed to explain the mechanism of MAC. The first, commonly referred to as the "Field Cancerization Theory", postulates that MAC simply reflect mutations in the normal tissue surrounding the tumor resultant from concurrent exposure to carcinogens. If true, this theory implies that there is no clinical value of MAC. The second referred to as the "Humoral Theory of MAC" postulates a direct cause and effect relationship of malignancy to MAC. In this hypothesis, soluble chemical mediators are released from the malignant tissue which act on the normal tissue in the surrounding environment. In these studies an in vitro model was designed to mimic the interaction of malignant cells with normal bronchial epithelial cells. This model was employed to investigate the mechanism of MAC. It was shown that MAC can be induced in vitro demonstrating a cause and effect relationship of malignancy to MAC. Maximal induction of MAC was observed following 48 hours of direct co-culture of tumor cells with normal cells. The strength of MAC expression was found to be dose dependent indicating that this model can be utilized in future studies as a biological assay in the isolation of factors present in malignant conditioned medium capable of inducing MAC. These studies coupled with substantial evidence in vivo provide strong evidence supporting the Humoral mechanism of MAC.

description: Microtechnology becomes a versatile tool for biological and biomedical applications. Microwells have been established long but remained non-intelligent up to now. Merging new fabrication techniques and handling concepts with microelectronics enables to realize intelligent microwells suitable for future improved cancer treatment. The described technology depicts the basis for the fabrication of a elecronically enhanced microwell. Thin aluminium sheets are structured by laser micro machining and laminated successively to obtain registration tolerances of the respective layers of 5..10Â$μ$m. The microwells lasermachined into the laminate are with 50..80Â$μ$m diameter, allowing to hold individual cells within the well. The individual process steps are described and results on the microstructuring are given.

description: We report on studies of Classical Nova (CN) explosions where we follow the evolution of thermonuclear runaways (TNRs) on Carbon Oxygen (CO) white dwarfs (WDs). We vary both the mass of the WD (from 0.6 M$_\odot$ to 1.35 M$_\odot$) and the composition of the accreted material. Our simulations are guided by the results of multi-dimensional studies of TNRs in WDs that find sufficient mixing with WD core material occurs after the TNR is well underway, reaching levels of enrichment that agree with observations of CN ejecta abundances. We use NOVA (our 1-dimensional hydrodynamic code) to accrete solar matter until the TNR is ongoing and then switch to a mixed composition (either 25% WD material and 75% solar or 50% WD material and 50% solar). Because the amount of accreted material is inversely proportional to the initial $^{12}$C abundance, by first accreting solar matter the amount of material taking part in the outburst is larger than in those simulations where we assume a mixed composition from the beginning. Our results show large enrichments of $^7$Be in the ejected gases implying that CO CNe may be responsible for a significant fraction ($\sim$ 100 M$_\odot$) of the $^7$Li in the galaxy ($\sim$1000 M$_\odot$). In addition, although the ejected gases are enriched in WD material, the WDs in these simulations eject less material than they accrete. We predict that the WD is growing in mass as a consequence of the accretion-outburst-accretion cycle and CO CNe may be an important channel of Supernova Ia progenitors.
