description: Numerical optimization is used to design linear-optical devices that implement a desired quantum gate with perfect fidelity, while maximizing the success rate. For the 2-qubit CS (or CNOT) gate, we provide numerical evidence that the maximum success rate is $S=2/27$ using two unentangled ancilla resources; interestingly, additional ancilla resources do not increase the success rate. For the 3-qubit Toffoli gate, we show that perfect fidelity is obtained with only three unentangled ancilla photons -- less than in any existing scheme -- with a maximum $S=0.00340$. This compares well with $S=(2/27)^2/2 \approx 0.00274$, obtainable by combining two CNOT gates and a passive quantum filter [PRA 68, 064303 (2003)]. The general optimization approach can easily be applied to other areas of interest, such as quantum error correction, cryptography, and metrology [arXiv:0807.4906, PRL 99 070801 (2007)].

description: Happiness economics theorizes that economic growth is only tenuously connected to happiness. This article tests this theory on historical evidence by quantifying the trend in emotional well-being (EWB) of British men during the period of rapid industrialization between 1800 and 1900, using a digitized corpus of 19,682 pamphlets published in Britain during this period and held by JSTOR. EWB is measured between these years using a sentiment analysis method of quantifying the frequency over time of a set of positive-valence (“happy”) word groups relative to negative-valence (“sad”) word groups in the corpus, finding that it remains trendless throughout. This method thereby also provides insight into the quality of life of men during the Industrial Revolution.

description: Introduction: Decompilers are useful tools for software analysis and support in the absence of source code. They are available for many hardware architectures and programming languages. However, none of the existing decompilers support modern AMD GPU architectures such as AMD GCN and RDNA. Purpose: We aim at developing the first assembly decompiler tool for a modern AMD GPU architecture that generates code in the OpenCL language, which is widely used for programming GPGPUs. Results: We developed the algorithms for the following operations: preprocessing assembly code, searching data accesses, extracting system values, decompiling arithmetic operations and recovering data types. We also developed templates for decompilation of branching operations. Practical relevance: We implemented the presented algorithms in Python as a tool called OpenCLDecompiler, which supports a large subset of AMD GCN instructions. This tool automatically converts disassembled GPGPU code into the equivalent OpenCL code, which reduces the effort required to analyze assembly code.

description: Ultraviolet (UV) galaxies have been selected from GALEX. The presence of a FUV-dropout in their spectral energy distributions proved to be a very complete (83.3%) but not very efficient (21.4%) tool for identifying Lyman Break Galaxies (LBGs) at z~1. We divide the LBG sample into two sub-classes: red LBGs (RLBGs) detected at 24 micron which are mainly Luminous IR Galaxies (LIRGs) and blue LBGs (BLBGs) undetected at 24 microns down to 83 microJy. Two of the RLBGs are also detected at 70 micron. The median SED of the RLBGs is similar (above lambda~1 micron) to the dusty starburst HR10. However, unlike local (U)LIRGs, RLBGs are UV bright objects. We suggest that these objects contain a large amount of dust but that some bare stellar populations are also directly visible. The median SED of the BLBGs is consistent with their containing the same stellar population as the RLBGs but with a lower dust content. The luminosity function of our LBG sample at z~1 is similar to the luminosity function of NUV-selected galaxies at the same redshift. The integrated luminosity densities of z~1 LBGs and NUV-selected galaxies are very consistent. We show that star formation rates (SFRs) estimated from UV measurements and corrected using the IRX-beta method provide average total SFR_TOT in agreement with SFR_UV + SFR_dust. However, IRX-beta-based SFR_TOT shows a large dispersion. Summing up the detected UV (1150A rest-frame) and IR-based star formation rates of the detected objects, we find that only one third of the total (i.e. UV + dust) LBG SFR resides in BLBGs and two thirds in RLBGs, even though most LBGs at z~1 are BLBGs. On the other hand, the total SFR of LBGs accounts for only 11% of the total SFR at z~1. Finally, we observe a regular decrease of L_TIR / L_FUV from z=0 to z~2 for UV-selected samples.

description: The existence of exchange-coupled Ni$^{2+}$ ions -- the so-called magnetic dimers -- in wolframite-type NiWO$_4$ and Zn$_c$Ni$_{1-c}$WO$_4$ solid solutions with high nickel content was discovered by X-ray absorption spectroscopy combined with reverse Monte Carlo (RMC) simulations. Temperature- (10--300 K) and composition-dependent x-ray absorption spectra were measured at the Ni K-edge, Zn K-edge, and W L$_3$-edge of microcrystalline NiWO$_4$, Zn$_c$Ni$_{1-c}$WO$_4$ and ZnWO$_4$. Structural models were obtained from simultaneous analysis of the extended x-ray absorption fine structure (EXAFS) spectra at three metal absorption edges using RMC simulations. The obtained radial distribution functions for different atomic pairs made it possible to trace in detail the changes in the local environment of metal ions and the effect of thermal disorder. Dimerization of Ni$^{2+}$ ions within quasi-one-dimensional zigzag chains of [NiO$_6$] octahedra was evidenced in NiWO$_4$ in the whole studied temperature range. It manifests itself as the splitting of the Ni-Ni radial distribution function into two separate peaks. The effect is further preserved in solid solutions Zn$_c$Ni$_{1-c}$WO$_4$ for $c \leq 0.6$, which is related to the probability to find two Ni$^{2+}$ ions in neighboring positions.

description: We discuss the dynamics of microquasar jets in the interstellar medium, with specific focus on the effects of the X-ray binaries' space velocity with respect to the local Galactic standard of rest. We argue that, during late stages in the evolution of large scale radio nebulae around microquasars, the ram pressure of the interstellar medium due to the microquasar's space velocity becomes important and that microquasars with high velocities form the Galactic equivalent of extragalactic head-tail sources, i.e., that they leave behind trails of stripped radio plasma. Because of their higher space velocities, low-mass X-ray binaries are more likely to leave trails than high-mass X-ray binaries. We show that the volume of radio plasma released by microquasars over the history of the Galaxy is comparable to the disk volume and argue that a fraction of a few percent of the radio plasma left behind by the X-ray binary is likely mixed with the neutral phases of the ISM before the plasma is removed from the disk by buoyancy. Because the formation of microquasars is an unavoidable by-product of star formation, and because they can travel far from their birth places, their activity likely has important consequences for the evolution of magnetic fields in forming galaxies. We show that radio emission from the plasma inside the trail should be detectable at low frequencies. We suggest that LMXBs with high detected proper motions like XTE J1118+480 will be the best candidates for such a search.

Emission from dielectric cavities in terms of invariant sets of the chaotic ray dynamics

Subjects: subject: Optics (physics.optics)

description: In this paper, the chaotic ray dynamics inside dielectric cavities is described by the properties of an invariant chaotic saddle. I show that the localization of the far field emission in specific directions is related to the filamentary pattern of the saddle's unstable manifold, along which the energy inside the cavity is distributed. For cavities with mixed phase space, the chaotic saddle is divided in hyperbolic and non-hyperbolic components, related, respectively, to the intermediate exponential (tt_c) decay of the energy inside the cavity. The alignment of the manifolds of the two components of the saddle explains why even if the energy concentration inside the cavity dramatically changes from tt_c, the far field emission changes only slightly. Simulations in the annular billiard confirm and illustrate the predictions.

description: Recent advances in object segmentation have demonstrated that deep neural networks excel at object segmentation for specific classes in color and depth images. However, their performance is dictated by the number of classes and objects used for training, thereby hindering generalization to never seen objects or zero-shot samples. To exacerbate the problem further, object segmentation using image frames rely on recognition and pattern matching cues. Instead, we utilize the 'active' nature of a robot and their ability to 'interact' with the environment to induce additional geometric constraints for segmenting zero-shot samples. In this paper, we present the first framework to segment unknown objects in a cluttered scene by repeatedly 'nudging' at the objects and moving them to obtain additional motion cues at every step using only a monochrome monocular camera. We call our framework NudgeSeg. These motion cues are used to refine the segmentation masks. We successfully test our approach to segment novel objects in various cluttered scenes and provide an extensive study with image and motion segmentation methods. We show an impressive average detection rate of over 86% on zero-shot objects.

description: We report on detections of the high-excitation CO J=6-5, J=4-3 lines in Mrk231, a prototypical Ultra Luminous Infrared Galaxy (ULIRG) and Seyfert 1 QSO. These observations are combined with CO J=3-2, HCN J=4-3 (this work), and CO J=2-1, J=1-0, 13CO J=2-1, HCN J=1-0 measurements taken from the literature to provide better constraints on the properties of the molecular gas in an extreme starburst/QSO in the local Universe. We find that the CO J=4-3 and J=6-5 transitions trace a different gas phase from that dominating the lower three CO transitions, with n(H_2) ~ (1-3)x10^4 cm-3 and Tk ~ (40-70) K. This phase is responsible for the luminous HCN emission, and contains most of the H2 gas mass of this galaxy. The total CO line cooling emanating from this dense phase is found similar to that of the [CII] line at 158 micron, suggesting a very different thermal balance to that seen in lower IR-luminosity galaxies, and one likely dominated by dense photon-dominated regions. Our dense "sampling" of the CO rotational ladder and the HCN lines enables us to produce well-constrained Spectral Line Energy Distributions (SLEDs) for the dense molecular gas in Mrk231 and compare them to those of high redshift starbursts, many of which have SLEDs that may be affected by strong lensing. Finally, we use our local molecular line excitation template to assess the capabilities of future cm and mm/sub-mm arrays in detecting CO and HCN transitions in similar systems throughout the local and distant universe.

description: In this letter, we investigate a receiver architecture, which uses the received signal in order to simultaneously harvest energy and estimate a Gauss-Markov linear process. We study three communication scenarios: i) static channel, ii) Rayleigh block-fading channel, and iii) high power amplifier (HPA) nonlinearities at the transmitter side. Theoretical results for the minimum mean square error as well as the average harvested energy are given for all cases and the fundamental tradeoff between estimation quality and harvested energy is characterized. We show that channel fading improves the estimation performance while HPA requires an extended Kalman filter at the receiver and significantly affects both the estimation and the harvesting efficiency.

description: This thesis investigated the integration of pharmacological and phytochemical data of medicinal plants from the Cree of Eeyou Istchee in Northern Quebec. Data from these 17 plant extracts were assessed for patterns of biological activity and chemical signals that could be explained by taxonomic or plant organ groupings. The Squamish medicinal plant Oplopanax horridus (Sm.) Miq. was also assessed for enzyme inhibition activity across multiple extracts and for bioactive compounds using an untargeted metabolomics approach. A comprehensive data set was assembled documenting the relative activities on the 17 plant extracts in 69 cell-free and cell-based bioassays covering activity on glucohomeostasis, effects of hyperglycemia, and capacity for enzyme inhibition. Multivariate analysis suggests that the leaf part extracts are particularly associated with antioxidant and antiglycation activities, while another discrete group of extracts associate strongly with other sets of glucohomeostasis assays. The activity of extracts on enzyme inhibition appears to be the factor most strongly driving the majority of activity patterns, likely because extracts that interact strongly with more metabolic enzymes will have more effects on other targets in the body. The phytochemical profiles of the Cree medicinal plants were assessed in two ways. First, spectroscopic and chromatographic data for the plant extracts was compared to a database of phytochemical standards using a proprietary Waters software, UNIFI, to match known signals of chemical standards to unidentified peaks in the plant extracts. Second, similarly collected spectroscopic data for the Cree plant extracts was processed using the software MZMine for multivariate analysis in R, revealing the chemical diversity of the bark extracts in relation to the fruit and leaf extracts. Additionally, marker signals were determined for major sample groupings, and the capacity for this analytical approach to be used to tentatively identify unique compounds was demonstrated. Through bioassay guided fractionation of the O. horridus inner bark extract using the CYP 3A4 inhibition assay, the DCM subfraction midway through the non-polar elution on open column chromatography was determined to be the most potent. This fraction contained 10 major peaks on HPLC-DAD analysis. The hot water extract was found to have negligible activity on CYP 3A4 inhibition. Together, this research provides the first integrated look at the pharmacological and phytochemical data from across the Cree anti-diabetic medicinal plants in a statistical way, as well as providing a first look at O. horridus for inclusion in the anti-diabetes project.

description: In this paper we examine decision problems associated with various classes of convex languages, studied by Ang and Brzozowski (under the name "continuous languages"). We show that we can decide whether a given language L is prefix-, suffix-, factor-, or subword-convex in polynomial time if L is represented by a DFA, but that the problem is PSPACE-hard if L is represented by an NFA. In the case that a regular language is not convex, we prove tight upper bounds on the length of the shortest words demonstrating this fact, in terms of the number of states of an accepting DFA. Similar results are proved for some subclasses of convex languages: the prefix-, suffix-, factor-, and subword-closed languages, and the prefix-, suffix-, factor-, and subword-free languages.

description:
As a result of new global priorities, there is a growing need for high-quality evaluations of gender-integrated health programmes. This systematic review examined 99 peer-reviewed articles on evaluations of gender-integrated (accommodating and transformative) health programmes with regard to their theory of change (ToC), study design, gender integration in data collection, analysis, and gender measures used. Half of the evaluations explicitly described a ToC or conceptual framework (n = 50) that guided strategies for their interventions. Over half (61%) of the evaluations used quantitative methods exclusively; 11% used qualitative methods exclusively; and 28% used mixed methods. Qualitative methods were not commonly detailed. Evaluations of transformative interventions were less likely than those of accommodating interventions to employ randomised control trials. Two-thirds of the reviewed evaluations reported including at least one specific gender-related outcome (n = 18 accommodating, n = 44 transformative). To strengthen evaluations of gender-integrated programmes, we recommend use of ToCs, explicitly including gender in the ToC, use of gender-sensitive measures, mixed-method designs, in-depth descriptions of qualitative methods, and attention to gender-related factors in data collection logistics. We also recommend further research to develop valid and reliable gender measures that are globally relevant.

description: Reducing the complexity of large systems described as complex networks is key to understand them and a crucial issue is to know which properties of the initial system are preserved in the reduced one. Here we use random walks to design a coarse-graining scheme for complex networks. By construction the coarse-graining preserves the slow modes of the walk, while reducing significantly the size and the complexity of the network. In this sense our coarse-graining allows to approximate large networks by smaller ones, keeping most of their relevant spectral properties.

description: The propagation of compressional MHD waves is studied for an externally driven system. It is assumed that the combined action of the external sources and sinks of the entropy results in the harmonic oscillation of the entropy (and temperature) in the system. It is found that with the appropriate resonant conditions fast and slow waves get amplified due to the phenomenon of parametric resonance. Besides, it is shown that the considered waves are mutually coupled as a consequence of the nonequilibrium state of the background medium. The coupling is strongest when the plasma $β\approx 1$. The proposed formalism is sufficiently general and can be applied for many dynamical systems, both under terrestrial and astrophysical conditions.

Using Flare-Induced Modulation of Three- and Five-Minute Oscillations for Studying Wave Propagation in the Solar Atmosphere

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We propose a method for diagnosing the physical conditions in the solar atmosphere using an increase in oscillation amplitudes resulting from minuscule solar flares. As an example, we consider a B2 flare, which caused a sharp short-lived increase in the amplitude of three- and five-minute oscillations in the lower layers of the solar atmosphere. Enhanced three- and five-minute oscillations propagated from the lower layers of the atmosphere into the corona. Such short oscillation trains made it possible to remove the uncertainties arising in the measurements of the phase and group lags between the layers. In addition, the amplification of the oscillations that reach the corona may add to the likelihood of a repeated flare. Studying oscillations in small flare events has the advantage of exploring the atmosphere in its quasi-quiet condition as opposed to powerful flares, which cause substantial and prolonged disturbance of the environment. In addition, small flares are much more common than powerful flares, which allows one to choose from a larger sample of observational material.

description: Due to the increase in occurrence of natural disasters, it is imperative for our society to learn to maintain resiliency, while also preparing for the aftermath of a disaster. The major tasks of this proposal include providing emergency and permanent housing, within a condensed timeframe to a medium density while providing communal spaces and activities for long term use. New York City, the epicenter of the region and the country, can be catastrophically damaged by an earthquake or hurricane, particularly because of the density of population and lack of awareness of seismic risk. The quality of pre-disaster planning immediately results in a more successful post-disaster reconstruction, which directly impacts the future resiliency of the community. In order to decrease the timeframe between the disaster, emergency response, the relief phase, and the recovery of the community, a new building assembly system must be developed to solve this problem.

description: Using a high resolution cosmological simulation of reionization we have examined the differing structures formed by gas and dark matter at a redshift of 5.1. Baryon-rich regions form a small number of filaments, which connect the largest galaxies in the simulation. More detailed examination of the ten largest galaxies reveals long, slender gaseous filaments about 5 proper kpc in width radiating from the galaxy centers. Extending out from each filament are a few smooth, thin, nearly planar gaseous sheets. By contrast, the dark matter concentrates into quasi-spherical bodies. The results have implications for our understanding of structure formation in the early universe and of the Lyman alpha forest.

Lifetime positive lifestyle education aimed at reducing the incidence of coronary heart disease
Creators: name: Ornstein, William Sidney
Publisher: name: University of British Columbia
Year: 2010

description: A review of a portion of the vast amount of literature on the subject of Coronary Heart Disease reveals that although the incidence of mortality from this disease has declined by over 20 per cent since the 1960's, it is still a major cause of death in Canada. There seems to be general agreement that there are certain "risk factors" for Coronary- Heart Disease and that these can be modified positively by intervention such as education via the media, and counselling, as has been done in such studies as MRFIT, the Stanford Program, North Karelia, and "Know Your Body" Program. Many investigators now agree that Coronary Heart Disease is a "pediatric disease" and that measures to reduce the effects of the known risk factors should be initiated early in life. This reduction can best be achieved by an education program which commences at least as early as at the kindergarten level and continues throughout life in the school and in the work milieu. Governments will be the main source of funds for the development and implementation of health education programs, but will also provide support for the education and hiring of health educators. Other resources will be the health professionals in all disciplines and at all levels; industry, both at the occupational and consumer levels; the media; and various community facilities. In addition to incentives in the form of reduced insurance premiums offered by the private sector to participants in positive lifestyle programs, there could be tax incentives to individuals and to industry for such participation, or for the provision of facilities to encourage participation. It is suggested that the various programs aimed at helping Canadians to develop positive lifestyles for the prevention of Coronary Heart Disease be "married" into one inter-related, continuous program so that there is some rational relationship between programs at all levels. This would provide the continuous exposure necessary for enhancement of the learning process. Some recommendations are made for future studies.

description: Using Integral Field Unit (IFU) spectroscopy, we present here the spatially resolved morphologies of [SII]$λ$6717,6731/H$α$ and [SII]$λ$6717,6731/[OIII]$λ$5007 emission line ratios for the first time in a Blueberry Lyman-$α$ emitter (BBLAE) at z $\sim$ 0.047. Our derived morphologies show that the extreme starburst region of the BBLAE, populated by young ($\leqslant$ 10 Myr), massive Wolf-Rayet stars, is [SII]-deficient, while the rest of the galaxy is [SII]-enhanced. We infer that the extreme starburst region is density-bounded (i.e., optically thin to ionizing photons), and the rest of the galaxy is ionization-bounded $-$ indicating a Blister-type morphology. We find that the previously reported small escape fraction (10%) of Ly$α$ photons is from our identified density-bounded HII region of the BBLAE. This escape fraction is likely constrained by a porous dust distribution. We further report a moderate correlation between [SII]-deficiency and inferred Lyman Continuum (LyC) escape fraction using a sample of confirmed LyC leakers studied in the literature, including the BBLAE studied here. The observed correlation also reveals its dependency on the stellar mass and gas-phase metallicity of the leaky galaxies. Finally, the future scope and implications of our work are discussed in detail.
