Relative multiplexing for minimizing switching in linear-optical quantum computing

Many existing schemes for linear-optical quantum computing (LOQC) depend on multiplexing (MUX), which uses dynamic routing to enable near-deterministic gates and sources to be constructed using heralded, probabilistic primitives. MUXing accounts for the overwhelming majority of active switching demands in current LOQC architectures. In this manuscript, we introduce relative multiplexing (RMUX), a general-purpose optimization which can dramatically reduce the active switching requirements for MUX in LOQC, and thereby reduce hardware complexity and energy consumption, as well as relaxing demands on performance for various photonic components. We discuss the application of RMUX to the generation of entangled states from probabilistic single-photon sources, and argue that an order of magnitude improvement in the rate of generation of Bell states can be achieved. In addition, we apply RMUX to the proposal for percolation of a 3D cluster state in [PRL 115, 020502 (2015)], and we find that RMUX allows a 2.4x increase in loss tolerance for this architecture.Comment: Published version, New Journal of Physics, Volume 19, June 201

Acute Effects of Yoga on a Vibration Platform on Heart Rate, Blood Pressure, Flexibility, and Vertical Jump

Both yoga and whole-body vibration exercise may have a wide-range of positive effects independent of each other. PURPOSE: The purpose of this study was to examine the acute effects of yoga performed on and off a vibration platform on blood pressure, flexibility, and vertical jump. METHODS: Subjects (n = 14; 9 females, 5 males; mean age = 22.5 ±1.9) completed 3randomized protocols of yoga on and off a vibration platform. The testing protocols were: 1) yoga poses on vibration platform with low frequency and low amplitude (PPL), 2) yoga poses on platform with high frequency and high amplitude (PPH), and 3) traditional yoga performed on a flat, static surface (CON). Following a general warm-up, two trials (30 s rest between) of the vertical jump (CMJ) and the sit-and-reach test (SR) were performed by each subject. The best values for each test were recorded for statistical analysis. After the culmination of the pre-tests, the subjects performed two rounds of 8 different poses, holding each pose for 30 s, resting 60 s between each pose. HR and BP were taken between each pose during rest. HR and BP were recorded while the subject was at rest for 20 minutes (5-minute intervals) following protocols. RESULTS: There were no significant time*gender interaction, condition main effect, or time main effect for CMJ, however a significant time main effect was observed for SR (p\u3c0.01). A significant decrease in SBP was observed following the PPH session at the 10-minute mark post-exercise (p\u3c0.02). Diastolic blood pressure (DBP) showed a significant time difference (p\u3c0.03), and there was also a trend for time*gender interaction (p=0.062). Changes in DBP values following exercises were higher in males than the values in DBP seen in females. There were significant time main effect (p\u3c0.01) and significant time*gender interaction for heart rate (p\u3c0.01). CONCLUSION: The significant decrease in SBP following a bout of yoga on a vibration platform at high frequency and amplitude could be due to a greater activation of skeletal muscle resulting in a higher level of physiological changes such as increased local temperature, and/or by-products, and/or mechanical activity of muscle fiber leading to greater levels of vasodilation and decreased total peripheral resistance. The findings may have a practical application as an alternative treatment for high blood pressure. Future studies should investigate chronic effect of yoga on vibration platform on blood pressure

Relación entre biofilm de placa dental y exacerbaciones en pacientes con enfermedad pulmonar obstructiva crónica y bronquiectasias no fibroquística

Introducción: la enfermedad periodontal en los pacientes con EPOC está relacionada con el número y la gravedad de las exacerbaciones agudas en dicha población. Este estudio tiene como objetivo determinar si la presencia de placa dental bacteriana se asocia con el número y gravedad de las exacerbaciones en pacientes diagnosticados con EPOC y bronquiectasias no fibroquística. Métodos: estudio de cohortes históricas convertido a descriptivo en pacientes con EPOC y bronquiectasias no fibroquísticas que acudieron a la consulta de Neumología del Hospital Universitario de Canarias en fase estable y en tratamiento con broncodilatadores y/o esteroides inhalados. Se excluyeron pacientes con prótesis y pacientes edéntulos. Se cuantificó la placa dental bacteriana mediante el enjuague con floxina B 1,4% (Plac-Control® Revelador de Placa Líquido). Se preguntó por el tratamiento habitual, el número y gravedad de las exacerbaciones en los últimos 12 meses y los hábitos de higiene bucal. Resultados: se incluyeron 8 pacientes, 5 mujeres, todas diagnosticadas de BQNFQ (62,5%), y 3 varones, todos diagnosticados de EPOC (37,5%), con una media de edad de 57,5 años (DE = 17,7). 6 pacientes padecieron al menos 1 exacerbación, de los cuales, el 83,3% fueron de gravedad moderada. La media de exacerbaciones en 12 meses fue de 1.75 episodios por paciente (DE = 1,67). La media del porcentaje de placa dental teñida fue del 19% (DE = 10,95). Conclusión: debido a la imposibilidad de completar el estudio, no se pudo demostrar la hipótesis inicial. En caso de evidenciar la relación entre la placa dental bacteriana y las exacerbaciones de la EPOC y BQNFQ, proponemos una futura investigación en la que se pretende estudiar la aplicación de la técnica háptica con la mejoría de los síntomas de estas enfermedadesIntroduction: periodontal disease in COPD patients is related to the number and severity of acute exacerbations in this population. This study aims to determinate if the presence of bacterial dental plaque is associated with exacerbations in patients diagnosed with COPD and non-fibrocystic bronchiectasis. Methods: historical cohort study converted to descriptive study of patients diagnosed with COPD and non-fibrocystic bronchiectasis who came to the Pneumology area of the Hospital Universitario de Canarias in a stable clinic situation. Patients must had inhaled bronchodilators and/or steroids therapy. Patients with prosthesis and edentulous patients were excluded. Bacterial dental plaque was quantified by the mouthwash with phloxine B 1.4% (PlacControl® Revelador de Placa Líquido). We asked about the usual treatment, the number and severity of exacerbations in the last 12 months and oral hygiene habits. Results: we included 8 patients, 5 females, all of the diagnosed with NCFB (62.5%) and 3 males, all of the diagnosed with COPD (37.5%), with a mean age of 57.5 years (SD = 17.7). 6 patients had at least 1 exacerbation, 83.3% of them were moderate. The mean of exacerbations in 12 months was 1.75 episodes per patient (SD = 1.67). The mean percentage of stained dental plaque was 19% (SD = 10.95). Conclusions: due to the impossibility of completing the study, the initial hypothesis could not be demonstrated. In case of evidencing the relationship between bacterial dental plaque and exacerbations of COPD and NCFB, we propose a future investigation in which it is intended to study the application of the haptic technique with the improvement of the symptoms of these diseases

Modeling multiple ecosystem services, biodiversity conservation, commodity production, and tradeoffs at landscape scales

Nature provides a wide range of benefits to people. There is increasing consensus about the importance of incorporating these ecosystem services into resource management decisions, but quantifying the levels and values of these services has proven difficult. We use a spatially explicit modeling tool, Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST), to predict changes in ecosystem services, biodiversity conservation, and commodity production levels. We apply InVEST to stakeholder-defined scenarios of land-use/land-cover change in the Willamette Basin, Oregon. We found that scenarios that received high scores for a variety of ecosystem services also had high scores for biodiversity, suggesting there is little tradeoff between biodiversity conservation and ecosystem services. Scenarios involving more development had higher commodity production values, but lower levels of biodiversity conservation and ecosystem services. However, including payments for carbon sequestration alleviates this tradeoff. Quantifying ecosystem services in a spatially explicit manner, and analyzing tradeoffs between them, can help to make natural resource decisions more effective, efficient, and defensible. © The Ecological Society of America

Grain size-dependent thermal conductivity of polycrystalline twisted bilayer graphene

Abstract We report the room temperature thermal conductivity of polycrystalline twisted bilayer graphene (tBLG) as a function of grain size measured by employing a noncontact optical technique based on micro-Raman spectroscopy. Polycrystalline tBLG sheets of different grain sizes were synthesized on copper by hot filament chemical vapor deposition. The thermal conductivity values are 1305 ± 122 , 971 ± 73 , and 657 ± 42 W m − 1 K − 1 for polycrystalline tBLG with average grain sizes of 54, 21, and 8 nm, respectively. Based on these thermal conductivity values, we also estimated the grain boundary conductance, 14.43 ± 1.21 × 10 10 W m − 2 K − 1 , and the thermal conductivity for single crystal tBLG, 1510 ± 103 W m − 1 K − 1 . Our results show that the relative degradation of thermal conductivity due to grain boundaries is smaller in bilayer than in monolayer graphene. Molecular dynamics simulations indicate that interlayer interactions play an important role in the heat conductivity of polycrystalline bilayer graphene. The quantitative study of the grain size dependent thermal conductivity of polycrystalline bilayer graphene is valuable in technological applications as well as for fundamental scientific understanding

Rice Galaxy: An open resource for plant science

Background: Rice molecular genetics, breeding, genetic diversity, and allied research (such as rice-pathogen interaction) have adopted sequencing technologies and high-density genotyping platforms for genome variation analysis and gene discovery. Germplasm collections representing rice diversity, improved varieties, and elite breeding materials are accessible through rice gene banks for use in research and breeding, with many having genome sequences and high-density genotype data available. Combining phenotypic and genotypic information on these accessions enables genome-wide association analysis, which is driving quantitative trait loci discovery and molecular marker development. Comparative sequence analyses across quantitative trait loci regions facilitate the discovery of novel alleles. Analyses involving DNA sequences and large genotyping matrices for thousands of samples, however, pose a challenge to non−computer savvy rice researchers. Findings: The Rice Galaxy resource has shared datasets that include high-density genotypes from the 3,000 Rice Genomes project and sequences with corresponding annotations from 9 published rice genomes. The Rice Galaxy web server and deployment installer includes tools for designing single-nucleotide polymorphism assays, analyzing genome-wide association studies, population diversity, rice−bacterial pathogen diagnostics, and a suite of published genomic prediction methods. A prototype Rice Galaxy compliant to Open Access, Open Data, and Findable, Accessible, Interoperable, and Reproducible principles is also presented. Conclusions: Rice Galaxy is a freely available resource that empowers the plant research community to perform state-of-the-art analyses and utilize publicly available big datasets for both fundamental and applied science
