description: Most of the approaches for indoor RGBD semantic la- beling focus on using pixels or superpixels to train a classi- fier. In this paper, we implement a higher level segmentation using a hierarchy of superpixels to obtain a better segmen- tation for training our classifier. By focusing on meaningful segments that conform more directly to objects, regardless of size, we train a random forest of decision trees as a clas- sifier using simple features such as the 3D size, LAB color histogram, width, height, and shape as specified by a his- togram of surface normals. We test our method on the NYU V2 depth dataset, a challenging dataset of cluttered indoor environments. Our experiments using the NYU V2 depth dataset show that our method achieves state of the art re- sults on both a general semantic labeling introduced by the dataset (floor, structure, furniture, and objects) and a more object specific semantic labeling. We show that training a classifier on a segmentation from a hierarchy of super pixels yields better results than training directly on super pixels, patches, or pixels as in previous work.

description: In studies evaluating the accuracy of diagnostic tests, three designs are commonly used, crossover, randomized, and noncomparative. Existing methods for meta-analysis of diagnostic tests mainly consider the simple cases in which the reference test in all or none of the studies can be considered a gold standard test, and in which all studies use either a randomized or noncomparative design. The proliferation of diagnostic instruments and the diversity of study designs create a need for more general methods to combine studies that include or do not include a gold standard test and that use various designs. This article extends the Bayesian hierarchical summary receiver operating characteristic model to network meta-analysis of diagnostic tests to simultaneously compare multiple tests within a missing data framework. The method accounts for correlations between multiple tests and for heterogeneity between studies. It also allows different studies to include different subsets of diagnostic tests and provides flexibility in the choice of summary statistics. The model is evaluated using simulations and illustrated using real data on tests for deep vein thrombosis, with sensitivity analyses. Supplementary materials for this article are available online.

description: Abstract: Both Russian and Chinese governments declare current status of state-to-state relations as all-inclusive partnership and strategic cooperation. The development of ties between Russia and China, including the field of higher education, has reached its climax. The main reason for this was the painful break in relations between Russian universities and universities in Western countries after 2022 that can be compared with a new iron curtain for Russia.

The object of the research is the development of universities in Russia and China. The subject of the research is a complex of factors that influenced the more successful development of Chinese universities compared to Russian ones. The purpose of the study is to consider a variety of factors that influenced more successful development of Chinese universities compared to Russian ones, including measures of state support conveyed through the university development programs in Russia and China.

The research question is why Chinese universities managed to take leading positions in world university rankings, while Russian universities failed to do so. When analyzing government support programs for Chinese and Russian universities, information from the official websites of these development programs was used. The methods used were comparative analysis, analysis and synthesis of empirical data. The scientific novelty of the research lies in the establishment of a high degree of similarity in government support for university development programs in Russia and China, and the analysis of the factors contributing to the more successful development of the Chinese higher education system.

Based on the research, it was concluded that the mechanisms for reforming higher education systems in Russia and China have much in common. Development programs in Russian and Chinese universities are also similar. Chinese universities have achieved greater success in their development due to the more successful development of China in general. Today China is the second largest economy in the world. China has the world's largest education system in the world, and has more opportunities to develop international cooperation. The success of Chinese university development programs was also influenced by a more innovative nature of the Chinese economy compared to Russia. The need to develop higher education in China was determined by the development of the Chinese economy, and was not just an isolated project determined by the ambitions of the country's leadership.

description: We perform fully three-dimensional simulations, using the truncated Wigner method, to investigate the reflection of Bose-Einstein condensates from abrupt potential barriers. We show that the inter-atomic interactions can disrupt the internal structure of a cigar-shaped cloud with a high atom density at low approach velocities, damping the center-of-mass motion and generating vortices. Furthermore, by incorporating quantum noise we show that scattering halos form at high approach velocities, causing an associated condensate depletion. We compare our results to recent experimental observations.

A backward Monte-Carlo method for time-dependent runaway electron simulations

description: Kinetic descriptions of runaway electrons (RE) are usually based on Fokker-Planck models that determine the probability distribution function (PDF) of RE in 2-dimensional momentum space. Despite of the simplification involved, the Fokker-Planck equation can rarely be solved analytically and direct numerical approaches (e.g., continuum and particle-based Monte Carlo (MC)) can be time consuming, especially in the computation of asymptotic-type observables including the runaway probability, the slowing-down and runaway mean times, and the energy limit probability. Here we present a novel backward MC approach to these problems based on backward stochastic differential equations (BSDEs) that describe the dynamics of the runaway probability by means of the Feynman-Kac theory. The key ingredient of the backward MC algorithm is to place all the particles in a runaway state and simulate them backward from the terminal time to the initial time. As such, our approach can provide much faster convergence than direct MC methods (by significantly reducing the number of particles required to achieve a prescribed accuracy) while at the same time maintaining the advantages of particle-based methods (compared to continuum approaches). The proposed algorithm is unconditionally stable, can be parallelized as easy as the direct MC method, and its extension to dimensions higher than two is straightforward, thus paving the way for conducting large-scale RE simulation.

description: Large area surveys will dominate the forthcoming decades of astronomy and their success requires characterizing thousands of discoveries through additional observations at higher spatial or spectral resolution, and at complementary cadences or periods. Only the full automation of adaptive optics systems will enable high-acuity, high-sensitivity follow-up observations of several tens of thousands of these objects per year, maximizing on-sky time. Automation will also enable rapid response to target-of-opportunity events within minutes, minimizing the time between discovery and characterization. In June 2012, we demonstrated the first fully automated operation of an astronomical adaptive optics system by observing 125 objects in succession with the Robo-AO system. Efficiency has increased ever since, with a typical night comprising 200-250 automated observations at the visible diffraction limit. By observing tens of thousands of targets in the largest-ever adaptive-optics surveys, Robo-AO has demonstrated the ability to address the follow-up needs of current and future large astronomical surveys.

description: We study the effect of different heating rates of a dilute Bose gas confined in a quasi-1D finite, leaky box. An optical kicked-rotor is used to transfer energy to the atoms while two repulsive optical beams are used to confine the atoms. The average energy of the atoms is localized after a large number of kicks and the system reaches a nonequilibrium steady state. A numerical simulation of the experimental data suggests that the localization is due to energetic atoms leaking over the barrier. Our data also indicates a correlation between collisions and the destruction of the Bose-Einstein condensate fraction.

description: Considering clinical benefits of new combination therapies for metastatic renal-cell carcinoma (mRCC), this study aims to calculate the number needed to treat (NTT) and the cost of preventing an event (COPE) for pembrolizumab plus axitinib (P + A), and nivolumab plus ipilimumab (N + I) as first-line treatments, from the Brazilian private perspective. Overall survival (OS) and progression-free survival (PFS) data for intermediate- and poor-risk groups were obtained from KEYNOTE-426 and CHECKMATE-214 trials for P + A and N + I, respectively, versus sunitinib as mRCC first-line treatment. Considering a 12-month time horizon, 6 patients should be treated with P + A to prevent one death with sunitinib use, resulting in a COPE of 3,893,903 BRL. Using N + I, NNT for 12-month OS rate was 13 compared to sunitinib, with a COPE of 6,357,965 BRL. Regarding PFS data, NNT was also 6 when comparing P + A versus sunitinib, with an estimated COPE of 3,893,903 BRL. Estimated NNT was 20 comparing N + I and sunitinib, resulting in a COPE of 10,172,744 BRL. Cost differences between two treatment options, reached more than 6 million BRL for PFS, and 2 million BRL for OS. At the 12-month landmark, P + A suggests better economic scenario versus N + I as first-line mRCC treatment option for intermediate- and poor-risk groups, through an indirect comparison using sunitinib as a common comparator.

In a Stark-decelerator beamline pulsed electric fields are used to decelerate OH radicals and subsequently store them in an electrostatic trap. The efficiency of the deceleration and trapping process is determined by the exact timings of the applied electric field pulses. Automated optimization of these timings yields an increase of 40 % of the number of trapped OH radicals.

Special emphasis is put on a fully numerical framework involving four-dimensional regulators preserving Euclidean O(4) and Minkowski Lorentz invariance, an important prerequisite for future applications. Pion and sigma meson spectral functions are calculated for a wide range of temperatures across the phase transition illustrating the applicability of the general framework for finite temperature applications. In addition, various aspects concerning the interplay between the Euclidean and real time two-point function are discussed.

description: Background: Botulism is a fatal illness if not diagnosed early and treated adequately. Aim: The aim of this research was to assess the clinical and evolutionary patterns of foodborne botulism. Materials and Methods: Data from four botulism cases was analysed retrospectively.Epidemiological causes, clinical manifestations, and specific bioassay findings for botulinum neurotoxin identification all supported a positive diagnosis. Results: Serum samples tested positive for type B botulinum toxin. Under treatment with polyvalent antibotulinum serum evolution was positive for three cases, the forth requiring intensive care and mechanical ventilation but with recovery after months of rehabilitation. Conclusion: Botulism/food poisoning can be caused by consuming inappropriately canned and stored food.

description: In a recent paper [Phys. Lett.

In the present letter we extend these results to a system which is out of equilibrium and evolves to a stationary state according to a nonlinear Fokker-Planck equation. By means of time-scale conversion, it is shown that there exists a ``correspondence'' among the self-similar solutions of the nonlinear Fokker-Planck equations associated with the different Tsallis formalisms. The time-scale conversion is related to the corresponding Lyapunov functions of the respective nonlinear Fokker-Planck equations.

description: We report results from an ASCA X-ray study of DEM L316, an emission nebula in the Large Magellanic Cloud (LMC) consisting of two closely-spaced supernova remnants (SNRs). The SIS image shows separate X-ray sources located at the positions of the two radio- and optically-emitting SNR shells, 0547$-$69.7A and 0547$-$69.7B (hereafter, shell A and B). The individual X-ray spectrum of each shell is well described by optically-thin thermal emission, although the characteristics of the emission differ in important details between them. Shell A exhibits strong iron L emission, which we attribute to the presence of iron-rich ejecta leading to the suggestion that this SNR originates from a Type Ia SN, an explosion of a moderate mass progenitor. Shell B, on the other hand, has a chemical composition similar to that of the interstellar medium of the LMC and so its X-ray emission is dominated by swept-up matter. The different spectral features strongly disfavor the hypothesis that the two shells are due to one supernova explosion into an interconnected bubble. We could not obtain the evidence which positively supports the collision between two SNRs.

description: The standard model of GRB afterglows assumes that relativistically expanding material is decelerating due to interaction with the surrounding medium. The afterglows are well described by the synchrotron radiation from a forward shock, while the strong optical flash associated with GRB 990123 can be attributed to the emission from a reverse shock. We give a detailed study on the reverse shock emission. The full light curves are calculated for a long and a short GRB cases. We discuss the lack of the prompt optical detections by ROTSE for GRB 981121 and GRB 981223.

The corresponding unique theorem is proved. It is shown that the obtained two-parameter Shannon additivity is a natural consequence from the Leibniz rule of the two-parameter Chakrabarti-Jagannathan difference operator.

description: Mid-infrared dual-comb spectroscopy has the potential to supplant conventional high-resolution Fourier transform spectroscopy in applications that require high resolution, accuracy, signal-to-noise ratio, and speed. Until now, dual-comb spectroscopy in the mid-infrared has been limited to narrow optical bandwidths or to low signal-to-noise ratios. Using a combination of digital signal processing and broadband frequency conversion in waveguides, we demonstrate a mid-infrared dual-comb spectrometer that can measure comb-tooth resolved spectra across an octave of bandwidth in the mid-infrared from 2.6-5.2 $μ$m with sub-MHz frequency precision and accuracy and with a spectral signal-to-noise ratio as high as 6500. As a demonstration, we measure the highly structured, broadband cross-section of propane (C3H8) in the 2860-3020 cm-1 region, the complex phase/amplitude spectrum of carbonyl sulfide (COS) in the 2000 to 2100 cm-1 region, and the complex spectra of methane, acetylene, and ethane in the 2860-3400 cm-1 region.

description: We introduce a simple model for the formation of voids. In this model the underdensity of galaxies in voids is the product of two factors. The first arises from a gravitational expansion of the negative density perturbation. The second is due to biasing: galaxies are less likely to form in an underdense region. One feature of the model is an upper cutoff in void sizes. We calculate the volume filling factor of characteristic voids for different CDM models and find that our formation model points to $Λ$CDM models as preferred models of the power spectrum. A natural consequence of our model is that the underdensity of the dark matter inside voids is smaller than the galaxy underdensity.

This article review is a chapter from PhD thesis that identified the perspective of health professional and patients about the nursing role during pediatric asthma management based Burawoy’s extended case method. A qualitative paradigm was deemed to be most appropriate to fully grasp the meanings that the participants attach to the phenomenon of childhood asthma management. Then, this review described a a new Nursing Role Development Model as a way of conceptualising the nursing role generally, in order to recognize the importance of multi-level environments as well as interactions between the levels as key factors influencing development which may applied to the field in Saudi Arabia. The impact of the clinical nurse specialist enhances patient care and promotes professional nursing practice. This article provides a review of the asthma management and its challenges, a description of multifactor such as professional power, policy, culture and gender roles on stakeholders’ perceptions of nurses in general and asthma nurse specialists in particular, and a discussion of opportunities and potential threats to future growth of the clinical nurse specialist role.

description: This essay presents a critical evaluation of the concepts of string theory and its impact on particle physics. The point of departure is a historical review of four decades of string theory within the broader context of six decades of failed attempts at an autonomous S-matrix approach to particle theory. The central message, contained in sections 5 and 6, is that string theory is not what its name suggests, namely a theory of of objects in spacetime whose localization is string- instead of point-like. Contrary to popular opinion the oscillators corresponding to the Fourier models of a quantum mechanical string do not cause a stringlike spatial extension of the object under discussion and neither does the "range space" of a chiral conformal QFT acquire the interpretation of string-like localized quantum matter. Rather the superstring represents a solution of a problem which enjoyed some popularity in the 60s: the construction of infinite component wave function with a (realistic) mass/spin spectrum. The mass/spin tower "sits" over one point and does not arise from a string in spacetime. The widespread acceptance of a theory whose interpretation has been based on metaphoric reasoning had a corroding influence on particle theory, a point which will be illustrated in the last section with some remarks of a more sociological nature.

description: A major target of linguistics and cognitive science has been to understand what class of learning systems can acquire the key structures of natural language. Until recently, the computational requirements of language have been used to argue that learning is impossible without a highly constrained hypothesis space. Here, we describe a learning system that is maximally unconstrained, operating over the space of all computations, and is able to acquire several of the key structures present natural language from positive evidence alone. The model successfully acquires regular (e.g. $(ab)^n$), context-free (e.g. $a^n b^n$, $x x^R$), and context-sensitive (e.g. $a^nb^nc^n$, $a^nb^mc^nd^m$, $xx$) formal languages. Our approach develops the concept of factorized programs in Bayesian program induction in order to help manage the complexity of representation. We show in learning, the model predicts several phenomena empirically observed in human grammar acquisition experiments.

description: Thin films of CdTe were deposited on glass substrates by thermal evaporation. From the XRD measurements itis found that the films are of zinc-blende-type structure. Transmittance, absorption, extinction, and refractive coefficients are measured. Electronic structure, band parameters and optical spectra of CdTe were calculated from ab initio studies within the LDA and LDA+U approximations. It is shown that LDA underestimates the band gap, energy levels of the Cd-4d states, s-d coupling and band dispersion. However, it calculates the spin-orbit coupling correctly. LDA+U did not increase much the band gap value, but it corrected the s-d coupling by shifting the Cd-4d levels towards the experimentally determined location and by splitting the LDA-derived single s peak into two peaks, which originates from admixture of s and d states. It is shown that the sd coupling plays an important role in absorption and reflectivity constants. The calculated optical spectra fairly agree with experimental data. Independent of wave-vector scissors operator is found to be a good first approximation to shift rigidly the band gap of CdTe underestimated by LDA.

description: We establish an equidistribution result for push-forwards of certain locally finite algebraic measures in the adelic extension of the space of lattices in the plane. As an application of our analysis we obtain new results regarding the asymptotic normality of the continued fraction expansions of most rationals with a high denominator as well as an estimate on the length of their continued fraction expansions. By similar methods we also establish a complementary result to Zaremba's conjecture. Namely, we show that given a bound M, for any large q, the number of rationals $p/q\in [0,1]$ for which the coefficients of the continued fraction expansion of p/q are bounded by M is $o(q^{1-ε})$ for some $ε>0$ which depends on M.

description: We present an analysis of high dispersion spectra (R~40000) of three red clump stars in the old open cluster NGC 6819. The spectra were obtained with SARG, the high dispersion spectrograph of the Telescopio Nazionale Galileo. The spectra were analyzed using both equivalent widths measured with an automatic procedure, and comparisons with synthetic spectra. NGC 6819 is found to be slightly metal-rich ([Fe/H]= +0.09 +/-0.03, internal error); there are no previous high resolution studies to compare with. Most element-to-element abundance ratios are close to solar; we find a slight excess of Si, and a significant Na overabundance. Our spectra can also be used to derive the interstellar reddening towards the cluster, by comparing the observed colours with those expected from line excitation: we derive E(B-V)=0.14 +/-0.04, in agreement with the most recent estimate for this cluster.

description: In this study, we present Swift Linked Data Miner, an interruptible algorithm that can directly mine an online Linked Data source (e.g., a SPARQL endpoint) for OWL 2 EL class expressions to extend an ontology with new SubClassOf: axioms. The algorithm works by downloading only a small part of the Linked Data source at a time, building a smart index in the memory and swiftly iterating over the index to mine axioms. We propose a transformation function from mined axioms to RDF Data Shapes. We show, by means of a crowdsourcing experiment, that most of the axioms mined by Swift Linked Data Miner are correct and can be added to an ontology. We provide a ready to use Protégé plugin implementing the algorithm, to support ontology engineers in their daily modeling work.
title: Dispersion in optical configurations and sources for Optical Coherence Tomography

description: Optical coherence tomography is a biomedical imaging technique employed to visualize tissue structure, ocular vasculature and blood flow. An OCT system is a non-invasive biomedical imaging system that provides bi-dimensional and three-dimensional images of biological tissue with micrometer scale resolution and millimeter scale depth range. In clinical application, OCT is employed in vivo imaging of the human eye. Swept source optical coherence tomography (SS-OCT) is the latest and fastest method of scanning. However, there are several disadvantages of the SS-OCT such as: the decrease of the roll-off sensitivity as the depth of scanning increases and the presence of mirror terms in the OCT images. The main objective of the work presented throughout this thesis was to evaluate the effects of dispersion on the performance of OCT. This study extends the research from the optical configurations at the core of OCT systems to the optical sources, where we show that dispersion can be usefully employed to obtain sweeping. We prove that an akinetic swept source (AKSS) can be devised for the important band of OCT, 800 nm, where there is still no MHz swept source available. In a Michelson interferometer a Fourier domain optical delay line was used for dispersion compensation that subsequently was employed to control the dispersion in an OCT system. A first goal of this thesis was to increase dispersion in order to evaluate the possibility of removing mirror terms from the OCT images. Therefore, three methods of dispersion measurement were evaluated. The first method measures the full width half maximum of the autocorrelation function. The second method uses a super continuous laser and an acoustic-optic tunable filter to measure the path dispersion in the position of the autocorrelation peak. A third method consists in a fitting method applied to channeled spectra collected from the interferometer when using a mirror. A second goal of this thesis was to prove the usefulness of employing dispersion in building a SS. In the process of akinetic swept source optimization, several types of dispersive fibres were tested and the most optimum conditions for driving a semiconductor optical amplifier were established. A dual mode locking scheme was used to tune the akinetic swept source at MHz rates. The axial range of the swept source was evaluated by scanning through the channeled spectrum of a Michelson interferometer.
