description: We report results of the first search to date for continuous gravitational waves from unstable r-modes from the pulsar J0537-6910. We use data from the first two observing runs of the Advanced LIGO network. We find no significant signal candidate and set upper limits on the amplitude of gravitational wave signals, which are within an order of magnitude of the spin-down values. We highlight the importance of having timing information at the time of the gravitational wave observations, i.e. rotation frequency and frequency-derivative values, and glitch occurrence times, such as those that a NICER campaign could provide.

description: Questions such as whether we live in a spatially finite universe, and what its shape and size may be, are among the fundamental open problems that high precision modern cosmology needs to resolve. These questions go beyond the scope of general relativity (GR), since as a (local) metrical theory GR leaves the global topology of the universe undetermined. Despite our present-day inability to predict the topology of the universe, given the wealth of increasingly accurate astro-cosmological observations it is expected that we should be able to detect it. An overview of basic features of cosmic topology, the main methods for its detection, and observational constraints on detectability are briefly presented. Recent theoretical and observational results related to cosmic topology are also discussed.

description: In this article, we propose an efficient method for sampling the relevant state space in condensed phase reactions. In the present method, the reaction is described by solving the electronic Schrödinger equation for the solute atoms in the presence of explicit solvent molecules. The sampling algorithm uses a molecular mechanics guiding potential in combination with simulated tempering ideas and allows thorough exploration of the solvent state space in the context of an ab initio calculation even when the dielectric relaxation time of the solvent is long. The method is applied to the study of the double proton transfer reaction that takes place between a molecule of acetic acid and a molecule of methanol in tetrahydrofuran. It is demonstrated that calculations of rates of chemical transformations occurring in solvents of medium polarity can be performed with an increase in the cpu time of factors ranging from 4 to 15 with respect to gas-phase calculations.

description: The Hawkes process has garnered attention in recent years for its suitability to describe the behavior of online information cascades. Here, we present a fully tractable approach to analytically describe the distribution of the number of events in a Hawkes process, which, in contrast to purely empirical studies or simulation-based models, enables the effect of process parameters on cascade dynamics to be analyzed. We show that the presented theory also allows predictions regarding the future distribution of events after a given number of events have been observed during a time window. Our results are derived through a differential-equation approach to attain the governing equations of a general branching process. We confirm our theoretical findings through extensive simulations of such processes. This work provides the basis for more complete analyses of the self-exciting processes that govern the spreading of information through many communication platforms, including the potential to predict cascade dynamics within confidence limits.

description: Apoptotic cells mediate the development of tolerogenic dendritic cells (DC) and thus facilitate induction and maintenance of peripheral tolerance. Following the identification of the evolutionary conserved annexin core domain (Anx) as a specific signal on apoptotic cells which antagonises Toll-like receptor (TLR) signalling, we examined whether the tolerogenic capacity of Anx can be exploited to downregulate antigen-specific immune responses. The treatment of bone marrow-derived dendritic cells (BMDC) with particles harbouring Anx as well as the model antigen ovalbumin (OVA) attenuated the response of OVA-specific OT-II T cells. The co-culture of Anx-particle-treated DC and T cells resulted in an anergy-like phenotype characterized by reduced proliferation and cytokine secretion. Here we demonstrate that the anti-inflammatory effects of Anx which are mediated through DC can be used as a tool to generate a particle-based antigen delivery system that promotes antigen-specific immunosuppression. Such Anx-particles may be a new therapeutic approach for the treatment of autoimmune diseases.

description: Context: Polarimetry is a very powerful tool to uncover various properties of astronomical objects that remain otherwise hidden in standard imaging or spectroscopic observations. However, the reliable measurement of the low polarization signal from astronomical sources requires a good control of spurious instrumental polarization induced by the various components of the optical system and the detector. Aims: We perform a detailed multi-wavelength calibration study of the FORS2 instrument at the VLT operating in imaging polarimetric mode (IPOL) to characterize the spatial instrumental polarization that may affect the study of extended sources. Methods: We use imaging polarimetry of a) high signal-to-noise blank fields BVRI observations during full-moon, when the polarization is expected to be constant across the field-of-view and deviations originate from the instrument and b) a crowded star cluster in broad-band RI and narrow-band Hα filters, where individual polarization values of each star across the field can be measured. Results: We find an instrumental polarization pattern that increases radially outwards from the optical axis of the instrument reaching up to 1.4% at the edges, depending on the filter. Our results are well approximated by an elliptical paraboloid down to less than {\sim0.05\%} accuracy,and {\sim0.02\%} when using non-analytic fits. We present 2D maps to correct for this spurious instrumental polarization. We also give several tips and tricks to analyze polarimetric measurements of extended sources. Conclusions: FORS2 is a powerful instrument allowing to map the linear polarimetry of extended sources. We present and discuss a methodology to measure the polarization of such sources, and to correct for the spatial polarization induced in the optical system. This methodology could be applied to polarimetric measurements using other dual-beam polarimeters.

description: Making use of the quantum Monte Carlo method based on the worm algorithm, we study the thermodynamic behavior of the S=1/2 isotropic Heisenberg antiferromagnet on the square lattice in a uniform magnetic field varying from very small values up to the saturation value. The field is found to induce a Berezinskii-Kosterlitz-Thouless transition at a finite temperature, above which a genuine XY behavior in an extended temperature range is observed. The phase diagram of the system is drawn, and the thermodynamic behavior of the specific heat and of the uniform and staggered magnetization is discussed in sight of an experimental investigation of the field-induced XY behavior.

description: We consider a classical and superadiabatic version of an iterative quantum adiabatic algorithm to solve combinatorial optimization problems. This algorithm is deterministic because it is based on purely classical dynamics, that is, it does not rely on any stochastic approach to mimic quantum dynamics. Moreover, use of shortcuts to adiabaticity makes the algorithm independent of the annealing time. We apply this algorithm to a certain class of hard instances of the 3-SAT problem. We find that more than 90\% of such 64-bits hard instances can be resolved by a few iteration. Our approach can also be used to analyze properties of instances themselves apart from stochastic uncertainty and shortage of adiabaticity.

The effect of oversampling and undersampling on classifying imbalanced text datasets

Publisher: name: The University of Texas at Austin
Year: 2004
Subjects: Imbalanced dataset problem

Resampling techniques

description: Many machine learning classification algorithms assume that the target classes share similar prior probabilities and misclassification costs. However, this is often not the case in the real world. The problem of classification when one class has a much lower prior probability in the training set is called the imbalanced dataset problem. One popular approach to solving the imbalanced dataset problem is to resample the training set. However, few studies in the past have considered resampling algorithms on data sets with high dimensionality. In this thesis, we examine the imbalanced dataset problem in the realm of text classification. Text has the added problems of both sparsity and high dimensionality. We first describe the resampling techniques we use in this thesis, including several resampling techniques we are introducing. After resampling, we classify the data using multinomial naïve Bayes, k nearest neighbor, and SVMs. Finally, we compare the results of our experiments and find that, while the best resampling technique to use is often dataset dependent, certain resampling techniques tend to perform consistently when coupled with certain classifiers

Three-component modeling of C-rich AGB star winds III. Micro-physics of drift-dependent dust formation
Creators: name: Sandin, C.
name: Hoefner, S.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A proper treatment of the non-equilibrium dust formation process is crucial in models of AGB star winds. In this paper the micro-physics of this process is treated in detail, with an emphasis on the effects of drift (drift models). We summarize the description of the dust formation process and make a few additions to previous work. A detailed study shows that different growth species dominate the grain growth rates at different drift velocities. The new models show that the net effect of drift is to significantly increase the amounts of dust, seemingly without affecting the mean wind properties, such as e.g., the mass loss rate. In some cases there is several times more dust in drift models, compared to the values in the corresponding non-drift models. We study the formation of a dust shell in the inner parts of the wind and find that drift plays an active role in accumulating dust to certain narrow regions. In view of the results presented here it is questionable if drift -- under the current assumptions -- can be ignored in the grain growth rates.

description: The central question of this paper is how to understand and characterize the parallel development of global private partnerships and other partnerships at the global level or national level, that all aim to promote sustainability of a global commodity. The aim of this paper is to contribute to the discussion on the role and use of global private partnerships in coping with sustainability as a wicked problem. For this purpose we have constructed and used a theoretical framework on complex decision-making processes with a grounded theory that explains diversity of private governance networks in terms of rivalry and exclusion. Focusing on five partnerships that promote sustainable production of soy in Brazil, the paper concludes that their development is highly interdependent and dialectical. One of the five partnerships is the Round Table on Responsible Soy. Both the start and development of this global private partnership have not ended but fuelled rivalry between different partnerships, herewith reproducing the wickedness of governance of sustainable production of soy. Managing sustainability as a wicked problem requires an understanding of the dialectical development of partnerships. Instead of embracing one partnership as the best or the benchmark, it may be wiser for policymakers to invest in managing interactions and articulating relationships between different partnerships at the global and national level.

description: First, using the law of large numbers, we analyze the setting principle of agricultural insurance premium rate, and take the case of setting of adult sow premium rate for study, to draw the conclusion that with the continuous promotion of agricultural insurance, increase in the types of agricultural insurance and increase in the number of the insured, the premium rate should also be adjusted opportunely. Then, on the basis of Bayes' theorem, we adjust and calibrate the claim frequency and the average claim, in order to correctly adjust agricultural insurance premium rate; take the case of forest insurance for premium rate adjustment analysis. In setting and adjustment of agricultural insurance premium rate, in order to make the expected results well close to the real results, it is necessary to apply the probability estimates in a large number of risk units; focus on the establishment of agricultural risk database, to timely adjust agricultural insurance premium rate.

description: Non-Hermitian quantum many-body systems are a fascinating subject to be explored. Using the generalized density matrix renormalisation group method and complementary exact diagonalization, we elucidate the many-body ground states and dynamics of a 1D interacting non-Hermitian Aubry-Andre-Harper model for bosons. We find stable ground states in the superfluid and Mott insulating regimes under wide range of conditions in this model. We reveal a skin superfluid state induced by the non-Hermiticity from the nonreciprocal hopping. We investigate the topology of the Mott insulating phase and find its independence of the non-Hermiticity. The topological Mott insulators in this non-Hermitian system are characterized by four equal Chern numbers and a quantized shift of biorthogonal many-body polarizations. Furthermore, we show generic asymmetric expansion and correlation dynamics in the system.

description: The agricultural energy consumption per unit of GDP is selected as an indicator for measuring the development level of low-carbon agriculture. Using gray relational theory, I analyze the relationship between development level of agricultural science and technology and development level of low-carbon agriculture in China. The results show that the correlation between the two is prominent; the number of agricultural science and technology talents, the number of agricultural science and technology patents, and the number of agricultural science and technology input are three major factors influencing the development of low-carbon agriculture. On this basis, I propose to take further effective measures, and put forth corresponding recommendations, in order to improve the level of agricultural science and technology.

For the thinner films, the lowest-energy state of the exciton is weakly indirect in momentum space, with its dispersion showing minima at a layer-number-dependent wave number, due to an inverted edge of a relatively flat topmost valence band branch of the InSe film spectrum and we compute the activation energy from the momentum dark exciton ground state into the bright state. For the films with more than seven In$_2$Se$_2$ layers, the exciton dispersion minimum shifts to $Γ$-point.

description: Empagliflozin (EGF) received USFDA approval in 2014 for oral use to control the glucose levels in adults with type 2 diabetes mellitus. Albeit, a systematic drug-excipient compatibility study of EGF has not been reported in the open literature. As physical and chemical interactions affect the performance of the formulation, this study intended to unveil the drug and excipients interactions which would later help in development of a robust solid dosage form. Differential scanning calorimetry (DSC) was applied as a screening tool for the assessment of compatibility between EGF and the list of excipients mentioned in the EMEA summary of product characteristics (SmPC)-section 6.1, along with mannitol and polyvinylpyrrolidone. Thermogravimetric analysis (TGA), Fourier Transform Infrared Spectroscopy (FTIR), X-ray Powder Diffraction (PXRD) and Hot Stage Microscopy (HSM) methods were utilized to appraise the interpretation of DSC results adequately. Isothermal stress testing (IST) studies of EGF were performed using the selected excipients to check the presence of interaction products (IPs) and the drug content by HPLC. Additional peaks were observed in the EGF-macrogol mixture than the drug peak in the HPLC analysis after two and half months, and those were separated and identified by the Ultra-High Performance Liquid Chromatography-Quadrupole Time of Flight Mass Spectrometry (UHPLC-QTOF-MS). Overall, EGF had shown compatibility with 13 selected excipients; however, initial observation of DSC and IST studies indicated plausible interaction of the EGF with macrogol.

The data included in the six illustrative cases presented in this report disclose wide variations in costs, prices, and returns to farmers, feeders, packers, wholesalers, and retailers who buy or sell live lambs or lamb carcasses at different times and under different conditions. Extreme variability in prices and returns to marketing agencies is demonstrated in the illustrative cases. Consequently, these cases emphasize some of the problems in calculating meaningful average margins and profits.

description: This article develops a fixed-time adaptive neural control method for the trajectory tracking of unknown marine surface vehicle (MSV) with output constraints. The developed controller is recursively designed under the fixed-time backstepping control framework. The barrier Lyapunov function (BLF) is introduced to handle the output constraints. The neural network (NN) identification and parametric adaptation technique are separately adopted to compensate for the model unknowns and disturbances. The stability argument shows that all error variables under the developed controller can regulate to the small neighbourhoods about zero in fixed time. The developed controller has the following two distinctive features. (1) The developed controller can acquire the fixed-time trajectory tracking while guaranteeing the constrained outputs simultaneously. (2) The developed controller is not only insensitive to model unknowns but also robust against disturbances. Lastly, simulated studies are given to demonstrate the obtained results.

description: Large-scale development of urban land use has led to change of a variety of natural processes and ecological processes, resulting in complex eco-environmental consequences. The objective of this study was to analyze the urban land use and its impact on air environment effect in Chengdu, western China from 1992 to 2008 following the RS (Remote Sensing) and GIS technique. The environmental effects data of urban land use was extracted and analyzed by overlaying layers of urban land use and the density of nitrogen dioxide and total suspended particulate matter in sampling points data concerning to the air quality of the environment in Chengdu based on GIS spatial analysis method. The results show that the main feature of urban land use change was substantial reduction of cultivated land and construction land and forest land increased significantly within the study area from1992 to 2008. The temporal-spatial change was notable in study period time. Land use has a significant impact on urban air environment, the chroma change of nitrogen dioxide derived from forest land was obvious, the area occupied by different nitrogen dioxide chroma was the largest. The urban land use impact on the highest class chroma of total suspended particulate matter was notable and its area was the greatest. The results show also the spatial distribution of nitrogen dioxide chroma and total suspended particulate matter chroma in study area is reduced following from Qingbaijiang District-Xindu District-downtown to both sides. The spatial distribution of industry, mining and traffic land is basically the same chroma spatial distribution. Therefore, the results of this study provide a scientific basis for improvement air environment quality, the urban sustainable development and a scientific response for decisions from the municipal governments.

description: Twisted bilayer graphene (TBG) hosts nearly flat bands with narrow bandwidths of a few meV at certain {\em magic} twist angles. Here we show that in twisted gapped Dirac material bilayers, or massive twisted bilayer graphenes (MTBG), isolated nearly flat bands below a threshold bandwidth $W_c$ are expected for continuous small twist angles up to a critical $θ_c$ depending on the flatness of the original bands and the interlayer coupling strength. Narrow bandwidths of $W \lesssim $30 meV are expected for $θ\lesssim 3^{\circ} $ for twisted Dirac materials with intrinsic gaps of $\sim 2$ eV that finds realization in monolayers of gapped transition metal dichalcogenides (TMDC), silicon carbide (SiC) among others, and even narrower bandwidths in hexagonal boron nitride (BN) whose gaps are $\sim 5$ eV, while twisted graphene systems with smaller gaps of a few tens of meV, e.g. due to alignment with hexagonal boron nitride, show vestiges of the magic angles behavior in the bandwidth evolution. The phase diagram of finite valley Chern numbers of the isolated moire bands expands with increasing difference between the sublattice selective interlayer tunneling parameters. The valley contrasting circular dichroism for interband optical transitions is constructive near $0^{\circ}$ and destructive near $60^{\circ}$ alignments and can be tuned through electric field and gate driven polarization of the mini-valleys. Combining massive Dirac materials with various intrinsic gaps, Fermi velocities, interlayer tunneling strengths suggests optimistic prospects of increasing $θ_c$ and achieving correlated states with large $U/W$ effective interaction versus bandwidth ratios.

description: Alhena A ($γ$ Gem A) is a bright Am star, with the strongest disc-integrated magnetic field strength reported so far for an Am star. Its spectrum exhibits standard circularly polarized Zeeman signatures, contrary to all previously studied Am stars that display abnormal signatures dominated by a single-signed lobe. We present here the result of follow-up observations of Alhena, using very high signal-to-noise spectropolarimetric data obtained over 25 observing nights with NARVAL at Télescope Bernard Lyot, in the frame of the BRITE (BRIght Target Explorer) spectropolarimetric survey. We confirm that Alhena A is magnetic and we determine its surface magnetic properties using different methods. Inclined dipole models are used to reproduce the longitudinal field measurements, as well as the Stokes V line profiles themselves. In both cases, the model is consistent with a polar field strength of $\sim$ 30 G. This is confirmed by a Zeeman-Doppler Imaging (ZDI) model, which also unveils smaller scale magnetic structures. A rotational period of 8.975 days was identified using intensity line profile variations. The ZDI inversion suggests that the surface magnetic field is sheared by differential rotation, with a difference in rotation rate between high and low latitudes at about 15\% of the solar value. This result challenges theories of the development of surface differential rotation in intermediate mass main sequence stars.

description: Experimental conditions for simultaneous measurements of transport coefficients of high temperature superconductors in zero and non-zero magnetic fields are analysed. Test measurements of the thermal conductivity, the thermoelectric power and the Nernst - Ettingshausen effect of a textured Bi2212 sample are reported in an external magnetic field of 2T. Errors related to parameters of the thermocouple used and to the spurious heat flows are discussed for a new experimental set-up built based on a closed cycle helium refrigerator. Possible optimising of experimental conditions is suggested.

description: The misuse and distortion of genetic science by white supremacists during the 20th century made genetic essentialism, the belief that genes can accurately predict complex behaviors and traits, a foundation of Western thinking. Today, essentialist assumptions remain embedded in US laws, policies, and cultural artifacts. To grow up in America is to be surrounded by many implicit and explicit messages that suggest genetic essentialism is ontologically accurate and to hear very few messages suggesting otherwise. Geneticists, especially those who study complex social behaviors, have a duty to make sure that their work is communicated clearly and carefully. They must anticipate the potential misuse of their work for nefarious purposes, such as white supremacism. Genetic scientists have a responsibility to explain, provide context for, and clarify their findings for public audiences. Those geneticists who wish to engage in public outreach will quickly find themselves combatting a mountain of essentialism. To effectively push back against this type of scientifically incorrect thinking, it is necessary to have the correct tools at one’s disposal. This collection aims to provide geneticists with a place to begin assembling their toolkit.
