description: We study the problem of online clustering where a clustering algorithm has to assign a new point that arrives to one of $k$ clusters. The specific formulation we use is the $k$-means objective: At each time step the algorithm has to maintain a set of k candidate centers and the loss incurred is the squared distance between the new point and the closest center. The goal is to minimize regret with respect to the best solution to the $k$-means objective ($\mathcal{C}$) in hindsight. We show that provided the data lies in a bounded region, an implementation of the Multiplicative Weights Update Algorithm (MWUA) using a discretized grid achieves a regret bound of $\tilde{O}(\sqrt{T})$ in expectation. We also present an online-to-offline reduction that shows that an efficient no-regret online algorithm (despite being allowed to choose a different set of candidate centres at each round) implies an offline efficient algorithm for the $k$-means problem. In light of this hardness, we consider the slightly weaker requirement of comparing regret with respect to $(1 + ε) \mathcal{C}$ and present a no-regret algorithm with runtime $O\left(T(\mathrm{poly}(log(T),k,d,1/ε)^{k(d+O(1))}\right)$. Our algorithm is based on maintaining an incremental coreset and an adaptive variant of the MWUA. We show that naïve online algorithms, such as \emph{Follow The Leader}, fail to produce sublinear regret in the worst case. We also report preliminary experiments with synthetic and real-world data.

description: We aimed to decrease our surgical site infection (SSI) rate by 30% by sequential implementation of vaginal cleansing and azithromycin for women who underwent a cesarean delivery (CD) after having labored or experienced rupture of membranes. This is a quality improvement project that assessed the stepwise implementation of two interventions within three time periods: (1) 12 months prior to implementation of either intervention; (2) 14 months of vaginal cleansing as infection prophylaxis; (3) 16 months of vaginal cleansing and azithromycin as infection prophylaxis. The primary outcome measure was the SSI as defined by the Center for Disease Control and Prevention and analyzed by control charts. The process measures were compliance rates of vaginal cleansing and azithromycin. Significance was detected by rules for determining a special cause variation. This study followed the SQUIRE 2.0 guidelines for reporting on quality improvement. There were 1033 patients included from the three study periods. The total rate of SSI decreased from 22.8% to 15.2% after implementing vaginal cleansing. Special cause variation was detected with an 8-point shift starting 4 months after implementation of vaginal cleansing. This decrease was sustained during the following 26 months. Adding azithromycin did not significantly lower the SSI rate further. When examined separately, deep SSI (p = .009) and endometritis (p = .001) significantly decreased in the post-intervention periods. Pre-operative vaginal cleansing compliance rose to 74%, and then further increased to 85% 1 year after implementation. Azithromycin compliance rose to 75%. Total length of postpartum stay decreased over the study periods from 3.5 ± 1.4 days to 3.2 ± 0.8 days (p = .001). In this quality improvement study, implementation of vaginal cleansing decreased the SSI rate by 33%, from 22.8% to 15.2%. The addition of azithromycin did not result in any additional change in SSI rate.

Inner Boundary Conditions for Advection-Dominated Accretion onto Black Holes

Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The structure of the inner region of an advection-dominated accretion disk around a nonrotating black hole is explored by applying asymptotic analysis in the region just outside the event horizon. We assume that the viscous transport is described by the standard Shakura-Sunyaev prescription throughout the disk, including the inner region close to the horizon. One of our goals is to explore the self-consistency of this assumption by analyzing the causality of the viscous transport near the black hole. The effects of general relativity are incorporated in an approximate manner by utilizing a pseudo-Newtonian gravitational potential. Analysis of the conservation equations yields unique asymptotic forms for the behaviors of the radial inflow velocity, the density, the sound speed, and the angular velocity. The specific behaviors are determined by three quantities; namely, the accreted specific energy, the accreted specific angular momentum, and the accreted specific entropy. The additional requirement of passage through a sonic point further constrains the problem, leaving only two free parameters. Our detailed results confirm that the Shakura-Sunyaev viscosity yields a well-behaved flow structure in the inner region that satisfies the causality constraint. We also show that the velocity distribution predicted by our pseudo-Newtonian model agrees with general relativity in the vicinity of the horizon. The asymptotic expressions we derive provide convenient boundary conditions for the development of global models via numerical integration of the conservation equations.

description: Bactofilins are a widespread family of cytoskeletal proteins with important roles in bacterial morpho-1 genesis, chromosome organization and motility. They polymerize in a nucleotide-independent manner, 2 forming non-polar filaments that are typically associated with the cytoplasmic membrane. Membrane 3 binding was suggested to be mediated by a short N-terminal peptide, but the underlying mechanism and 4 the conservation of this interaction determinant among bacteria remain unclear. Here, we use the bacto-5 filin homolog BacA of the stalked bacterium Caulobacter crescentus as a model to analyze the membrane-6 binding behavior of bactofilins. Based on site-directed mutagenesis of the N-terminal region, we identify 7 the full membrane-targeting sequence of BacA (MFSKQAKS) and identify amino acid residues that are 8 critical for its function in vivo and in vitro. Molecular dynamics simulations then provide detailed insight 9 into the molecular mechanism underlying the membrane affinity of this peptide.

description: We show that the position and width of the plasmon resonance in Silver are correctly predicted by ab--initio calculations including self--energy effects within the GW approximation. Unlike in simple metals and semiconductors, quasiparticle corrections play a key role and are essential to obtain Electron Energy Loss in quantitative agreement with the experimental data. The sharp reflectance minimum at 3.92 eV, that cannot be reproduced within DFT--LDA, is also well described within GW.The present results solve two unsettled drawbacks of linear response calculations for Silver.

description: Purpose: Verbs with low concreteness are frequent in discourse samples but rarely targeted in aphasia treatments for verbs. These verbs are an important part of functional communication, and recent studies have called for more research regarding aphasia and treatment stimuli with low concreteness. The aim of this study was to pilot the use of verbs with low concreteness in a novel sentence production intervention with persons with aphasia.Method: The study took the form of a single-case experimental design with multiple baselines across behaviors and across participants. Three persons with chronic nonfluent aphasia and apraxia of speech participated in the study. Each participant received treatment designed to increase the semantic networks of verbs with high frequency and low concreteness. Sentence production was closely examined over the course of treatment for treated and untreated verbs of varying concreteness levels. Additional measures of language and cognitive functioning were also taken before and after treatment.Results: Results indicated improved sentence production with target verbs attributable to the treatment in the 1st phase of 2 phases for 2 of the 3 participants. The increases corresponded with the application of treatment, despite the difference in number of baseline sessions for the participants. Where there were treatment effects, there was also considerable generalization to untreated sets of items during the 1st treatment phase. Word retrieval also improved for 2 participants.Conclusions: The results suggest that the novel treatment may improve sentence production and word retrieval in persons with aphasia, even when using target verbs with low concreteness ratings. Future research is warranted into the use of low concreteness verbs.

Unusual geometric percolation of hard nanorods in the uniaxial nematic liquid crystalline phase

description: We investigate by means of continuum percolation theory and Monte Carlo simulations how spontaneous uniaxial symmetry breaking affects geometric percolation in dispersions of hard rod-like particles. If the particle aspect ratio exceeds about twenty, percolation in the nematic phase can be lost upon adding particles to the dispersion. This contrasts with percolation in the isotropic phase, where a minimum particle loading is always required to obtain system-spanning clusters. For sufficiently short rods, percolation in the uniaxial nematic mimics that of the isotropic phase, where the addition of particles always aids percolation. For aspect ratios between twenty and infinity, but not including infinity, we find re-entrance behavior: percolation in the low-density nematic may be lost upon increasing the amount of nanofillers but can be re-gained by the addition of even more particles to the suspension. Our simulation results for aspect ratios of 5, 10, 20, 50 and 100 strongly support our theoretical predictions, with almost quantitative agreement. We show that a new closure of the connectedness Ornstein-Zernike equation, inspired by Scaled Particle Theory, is more accurate than the Lee-Parsons closure that effectively describes the impact of many-body direct contacts.

description: The generation and destruction of the supercurrent in a superconductor (S) between two resistive normal (N) current leads connected to a current source is computed from the source equation for the supercurrent density. This equation relates the gradient of the pair potential's phase to electron and hole wavepackets that create and destroy Cooper pairs in the N/S interfaces. Total Andreev reflection and supercurrent transmission of electrons and holes are coupled together by the phase rigidity of the non-bosonic Cooper-pair condensate. The calculations are illustrated by snapshots from a computer film.

description: The aggregation of the mixture of anionic surfactant – sodium dodecyl sulfate (SDS), and an anionic dye – bromocresol green sodium salt (BCG) was investigated by conductometric technique in water and alcoholic/diolic media within a temperature range of 300.55–320.55 K (with 5 K interval). The observed critical micelle concentration (cmc) decreases with surging of the concentration of BCG, following the same trend for β value. In presence of additives (ethanol, propanol, and ethylene glycol), the cmc value decreases up to a certain concentration and then the cmc values start enhancing with increasing concentration in all the cases. With the increased additive percentage, the β values continually decrease. Again, the cmc value increases gradually with the increase of temperature both in water and aq. additives media. The free energy of studied aggregation phenomena is negative which experiences an augmentation with the escalation of temperature. The increased negative value of free energy at elevated temperature indicates that the process becomes more spontaneous at a higher temperature. The ΔHm0 and ΔSm0 values reveal that the probable interaction forces between BCG and SDS are hydrophobic, ion-ion, as well as electrostatic interactions.

Optimal experimental design under irreducible uncertainty for linear inverse problems governed by PDEs

description: We present a method for computing A-optimal sensor placements for infinite-dimensional Bayesian linear inverse problems governed by PDEs with irreducible model uncertainties. Here, irreducible uncertainties refers to uncertainties in the model that exist in addition to the parameters in the inverse problem, and that cannot be reduced through observations. Specifically, given a statistical distribution for the model uncertainties, we compute the optimal design that minimizes the expected value of the posterior covariance trace. The expected value is discretized using Monte Carlo leading to an objective function consisting of a sum of trace operators and a binary-inducing penalty. Minimization of this objective requires a large number of PDE solves in each step. To make this problem computationally tractable, we construct a composite low-rank basis using a randomized range finder algorithm to eliminate forward and adjoint PDE solves. We also present a novel formulation of the A-optimal design objective that requires the trace of an operator in the observation rather than the parameter space. The binary structure is enforced using a weighted regularized $\ell_0$-sparsification approach. We present numerical results for inference of the initial condition in a subsurface flow problem with inherent uncertainty in the flow fields and in the initial times.

description: This study considers the issue of the transition of new farmers into U.S. agriculture, by examining land ownership and leasing trends. Our approach is to characterize the entire distribution by farmer age and farmer experience rather than using young versus old and beginning versus established farmer categories. We also use a linked-farms longitudinal approach instead of a repeated cross-sectional approach to show trends over time in farmland expansion and contraction. Differences in farm size are more pronounced based on farmer experience than farmer age, as farms operated by older beginning farmers tend to be smaller and do not tend to grow over time. We find that it is mostly young farmers as opposed to all beginning farmers that rapidly expand their farm operations after entering agriculture. Our findings inform policy makers about the strategies that young and beginning farmers use to start their businesses and expand over time and suggest more effective approaches for targeting loan programs to young and beginning farmers.

description: XMM-Newton observations of the NLS1 Markarian 896 are presented. Over the 2-10 keV band, an iron emission line, close to 6.4 keV, is seen. The line is just resolved and has an equivalent width of ~170 eV. The broad-band spectrum is well modelled by a power law slope of gamma ~ 2.03, together with two blackbody components to fit the soft X-ray excess. Using a more physical two-temperature Comptonisation model, a good fit is obtained for an input photon distribution of kT ~ 60eV and Comptonising electron temperatures of ~0.3 and 200 keV. The soft excess cannot be explained purely through the reprocessing of a hard X-ray continuum by an ionised disc reflector.

description: When a quantum field is in contact with a thermal bath, the vacuum state of the field may be generalized to a thermal vacuum state, which takes into account the thermal noise. In thermo field dynamics, this is realized by doubling the dimensionality of the Fock space of the system. Interestingly, the representation of thermal noise by means of an augmented space is also found in a distinctly different approach based on the Wigner transform of both the field operators and density matrix, which we pursue here. Specifically, the thermal noise is introduced by augmenting the classical-like Wigner phase space by means of Nosé-Hoover chain thermostats, which can be readily simulated on a computer. In this paper, we illustrate how this may be achieved and discuss how non-equilibrium quantum thermal distributions of the field modes can be numerically simulated.

description: In this article we address an online cutting problem with defects that arises in the food industry originally proposed by Glass and van Oostrum ([2010]. “Bun Splitting: A Practical Cutting Stock Problem.” Annals of Operations Research 179: 15–33): the Bun Splitting Problem. The problem involves splitting buns that are baked in large trays into package-size blocks while removing defective buns. Removing defective buns results in small blocks of buns that need to be assembled into package-size blocks at the subsequent packing phase. The primary objective in this splitting process is the minimisation of packing time; however, reducing the number of small blocks awaiting assembly is also a secondary concern. In this study, we relax simplifying assumptions imposed in the previous work to allow for multiple defects in the tray, production switchovers between different package sizes as well as a general defect distribution on the tray. We solve the resulting online cutting problem using a dynamic programming-based algorithm and demonstrate that the algorithm is capable of producing locally optimal solutions in a real-time production environment. We also discuss how the same approach can be adopted to other cutting problems with defects from various industries.

description: We study the compatibility of the AdS/CFT duality with the bulk and boundary causality, and derive a conformally invariant averaged null energy condition (CANEC) for quantum field theories in 3 and 5-dimensional curved boundaries. This is the generalization of the averaged null energy condition (ANEC) in Minkowski spacetime to curved boundaries, where null energy is averaged along the null line with appropriate weight for conformal invariance. For this purpose we take, as our guiding principle, the no-bulk-shortcut theorem of Gao and Wald, which essentially asserts that when going from one point to another on the boundary, one cannot take a "shortcut through the bulk". We also discuss the relationship between bulk vs boundary causality and the weak cosmic censorship.

description: Fruit production in the world is increasing continuously. Though in the past few years China and some South-American countries have extended their fruit producing areas, Europe remains to be one of the greatest fruit producers in the world. In the middle of Europe Hungary has to face several challenges as competing for market. Since yield risk has an important role in Hungarian fruit production we investigate the yield risk of two of the most important sour cherry varieties (’Újfehértói fürtös’ and ’Oblacsinszka’) grown in Újfehértó (1984-2005), moreover, two of the most important pear varieties (’Bosc Beurre’ and ’Williams’) grown in Bánfa and Zalasárszeg (1984- 2009). In the examined periods we analyse yield risk with different comparative methods such as E,V-efficiency, first and second degree as well as generalized stochastic dominance methods. We conclude that the production of sour cherry variety ’Oblacsinszka’ in Újfehértó is more preferable compared to the other sour cherry varieties and pear variety ’Bosc Beurre’ in Bánfa is more advantageous than the other pear varieties and sites.

description: We study numerically and analytically the coarsening of stripe phases in two spatial dimensions, and show that transient configurations do not achieve long ranged orientational order but rather evolve into glassy configurations with very slow dynamics. In the absence of thermal fluctuations, defects such as grain boundaries become pinned in an effective periodic potential that is induced by the underlying periodicity of the stripe pattern itself. Pinning arises without quenched disorder from the non-adiabatic coupling between the slowly varying envelope of the order parameter around a defect, and its fast variation over the stripe wavelength. The characteristic size of ordered domains asymptotes to a finite value $R_g \sim λ_0\ ε^{-1/2}\exp(|a|/\sqrtε)$, where $ε\ll 1$ is the dimensionless distance away from threshold, $λ_0$ the stripe wavelength, and $a$ a constant of order unity. Random fluctuations allow defect motion to resume until a new characteristic scale is reached, function of the intensity of the fluctuations. We finally discuss the relationship between defect pinning and the coarsening laws obtained in the intermediate time regime.

description: Previous studies have detected the association of polymorphisms in oxidative stress-related genes EPHX1 and MnSOD with pre-eclampsia (PE) risk, but the results are inconsistent among studies. Thus, a meta-analysis was performed to obtain more conclusive results. Eligible studies were retrieved in PubMed, Web of Science, EMBASE, Scopus, and CNKI. Odds ratios (ORs) with 95% confidence intervals (CIs) were utilized to evaluate the relationship between EPHX1 rs1051740, EPHX1 rs2234922, MnSOD rs4880 polymorphisms, and PE susceptibility in the genetic models. The subgroup analysis was also performed. Fourteen studies with a total of 4250 participants were included, including 1784 PE patients and 2466 healthy women. There was a statistically significant association between EPHX1 rs1051740 polymorphism and PE in Caucasians within the allele, dominant, heterozygous, and homozygous models (OR = 0.79, 95% CI = 0.64–0.98; OR = 0.64, 95% CI = 0.47–0.87; OR = 0.61, 95% CI = 0.44–0.85; OR = 0.63, 95% CI = 0.42–0.97, respectively). There was a statistically significant association between EPHX1 rs2234922 polymorphism and PE in Middle Easterners within the recessive and homozygous models (OR = 3.59, 95% CI = 1.25–10.32; OR = 3.99, 95% CI = 1.38–11.49, respectively). There was no statistically significant association between MnSOD rs4880 polymorphism and PE within five genetic models. Subgroup analysis didn’t reveal any association between MnSOD rs4880 polymorphism and PE in Asians, Caucasians, or Middle Easterners. This meta-analysis shows a significant association between the EPHX1 rs1051740 and PE risk in Caucasians. Meantime, there was a statistically significant association between EPHX1 rs2234922 polymorphism and PE in Middle Easterners.

description: We analyze Ge-related defects in Ge-doped SiO_2 using first-principles density functional techniques. Ge is incorporated at the level of ~ 1 mol % and above. The growth conditions of Ge:SiO_2 naturally set up oxygen deficiency, with vacancy concentration increasing by a factor 10^5 over undoped SiO_2, and O vacancies binding strongly to Ge impurities. All the centers considered exhibit potentially EPR-active states, candidates for the identification of the Ge(n) centers. Substitutional Ge produces an apparent gap shrinking via its extrinsic levels.

description: The rural life will have a new aspect within the European Union. The paper deals with the general term of ‘network’ which can refer to any interconnected group or system. It shows the lessons, experiences and the main obstacle of the networking activity, implemented is the former programming period, i.e. 2000-2006, and so for the current programming period, i.e. 2007-2013. It introduces the steps and structures to the Hungarian National Rural Network (HNRN), as an example. Officially the Article 68 of the Regulation 1698/2005/EC contains provisions as to the establishment of the National Rural Network, which aims at (a) identifying and analysing the best practises on rural development, providing information about them and organizing exchanges of experiences and know-how, and (b) preparing training programmes for local action groups in the process of formation and giving technical assistance for inter-territorial and trans-national cooperation between LAGs. Networking activity is looked upon as a permanent, improvable tool that can assist in developing the rural quality and economy. The paper introduces an evaluation on the willingness for cooperation on international field, which analysis was launched June 2009 among the Hungarian Local Action Groups (LAGs) by the HNRN. It shows that the successful adaptation to persistent rural acts will depend on many elements, as a result mainly on good practices and experiences. It is visible, that Hungary is also on the way of learning, and it has to draw the conclusion from time to time, the process of network building is drawn from the rural stakeholders and the wider rural economy point of view.

description: In a recent paper [Phys. Rev. Lett. 86, 63 (2001)], Li et al have reported that the nonequilibrium heat conducting steady state of a disordered harmonic chain is not unique. In this comment we point out that for a large class of stochastic heat baths the uniqueness of the steady state can be proved, and therefore the findings of Li et al could be either due to their use of deterministic heat baths or insufficient equilibration times in the simulations. We give a simple example where the uniquness of the steady state can be explicitly demonstrated.

description: 3D face alignment of monocular images is a crucial process in the recognition of faces with disguise.3D face reconstruction facilitated by alignment can restore the face structure which is helpful in detcting disguise interference.This paper proposes a dual attention mechanism and an efficient end-to-end 3D face alignment framework.We build a stable network model through Depthwise Separable Convolution, Densely Connected Convolutional and Lightweight Channel Attention Mechanism. In order to enhance the ability of the network model to extract the spatial features of the face region, we adopt Spatial Group-wise Feature enhancement module to improve the representation ability of the network. Different loss functions are applied jointly to constrain the 3D parameters of a 3D Morphable Model (3DMM) and its 3D vertices. We use a variety of data enhancement methods and generate large virtual pose face data sets to solve the data imbalance problem. The experiments on the challenging AFLW,AFLW2000-3D datasets show that our algorithm significantly improves the accuracy of 3D face alignment. Our experiments using the field DFW dataset show that DAMDNet exhibits excellent performance in the 3D alignment and reconstruction of challenging disguised faces.The model parameters and the complexity of the proposed method are also reduced significantly.The code is publicly available at https:// github.com/LeiJiangJNU/DAMDNet

description: Evaluating land use change in economic frameworks often requires non-market values to be assessed. However non-market valuation experiments can be sensitive to the way the trade offs are framed. The aim of the research reported in this paper was to examine the influence of varying the valuation scope and combination of attributes in a split sample choice experiment focused on assessing the impacts of increased mining activity (coal and coal seam gas) in the Surat Basin in southern Queensland, Australia. The region had traditionally been dominated by the agricultural sector. The survey was designed to assess the largely, but not exclusively, non-use values of a distant population (Brisbane (capital city) residents) for tradeoffs between positive and negative impacts, which incorporated economic, social and environmental issues. Four impact attributes were identified: A)local jobs in the mining sector; B) house prices in the non-mining sector; C) wage rates in the non-mining sector and, D) inspections and independent monitoring activity at coal seam gas mining sites (a proxy to address environmental concerns). The results indicate that varying the combination of attributes had a significant influence on preferences and welfare estimates, which varied across attributes and valuation formats,

description: The magnetoresistance associated with quantum interference corrections in a high mobility, gated InGaAs/InP quantum well structure is studied as a function of temperature, gate voltage, and angle of the tilted magnetic field. Particular attention is paid to the experimental extraction of phase-breaking and spin-orbit scattering times when weak anti- localization effects are prominent. Compared with metals and low mobility semiconductors the characteristic magnetic field $B_{tr} = \hbar/4eD τ$ in high mobility samples is very small and the experimental dependencies of the interference effects extend to fields several hundreds of times larger. Fitting experimental results under these conditions therefore requires theories valid for arbitrary magnetic field. It was found, however, that such a theory was unable to fit the experimental data without introducing an extra, empirical, scale factor of about 2. Measurements in tilted magnetic fields and as a function of temperature established that both the weak localization and the weak anti-localization effects have the same, orbital origin. Fits to the data confirmed that the width of the low field feature, whether a weak localization or a weak anti-localization peak, is determined by the phase-breaking time and also established that the universal (negative) magnetoresistance observed in the high field limit is associated with a temperature independent spin-orbit scattering time.
