description: It is becoming increasingly evident that the accurate assessment of fluid status is critical to ensure optimal care in patients undergoing hemodialysis (HD). Various fluid parameters, including overhydration (OH) and overhydration/extracellular water (OH/ECW%), which can be obtained using a bioimpedance spectroscopy device have been used to indicate the hydration status in such patients. This study aimed to explore the effect of these fluid parameters on cardiovascular events and determine which parameter was a better predictor of cardiovascular events (CVEs). A total of 227 patients who underwent HD at the Hangzhou Hospital of Traditional Chinese Medicine were enrolled in this prospective study between December 2017 and August 2018. Clinical data were collected, and the fluid status of patients was assessed using a body composition monitor. The patients were followed up until December 2020. The primary outcomes were CVEs. The association between fluid parameters and CVEs was analyzed using Cox proportional hazards models. The areas under the curve (AUCs) of receiver operating characteristic analysis and improvement in the global chi-squared value were used to compare the predictive values of fluid parameters for CVEs. During a median follow-up of 31 months, 66 CVEs were recorded. The patients with a higher absolute hydration index (OH) and a relative hydration index (OH/ECW%) exhibited an increased risk of developing CVEs. After adjusting for confounding factors, both OH [hazard ratio (HR) 1.279 per L, 95% confidence interval (CI) 1.047–1.562; p = 0.016] and OH/ECW% (HR 1.061 per %, 95% CI 1.017–1.108; p = 0.006) were independently associated with CVEs. The predictive ability of the absolute hydration index was superior to the relative hydration index based on AUC calculations for CVEs. Furthermore, a greater change in χ2 in predicting CVEs was noted for the absolute hydration index. Both absolute hydration index and relative hydration index were found to be independent predictors of CVEs in univariate and multivariate analyses. Furthermore, the absolute hydration index had a better additive predictive value than the relative hydration index in predicting CVEs.

description: We demonstrate that there is no ideal glass transition in a binary hard-disk mixture by explicitly constructing an exponential number of jammed packings with densities spanning the spectrum from the accepted ``amorphous'' glassy state to the phase-separated crystal. Thus the configurational entropy cannot be zero for an ideal amorphous glass, presumed distinct from the crystal in numerous theoretical and numerical estimates in the literature. This objection parallels our previous critique of the idea that there is a most-dense random (close) packing for hard spheres [Torquato et al, Phys. Rev. Lett., 84, 2064 (2000)].

description: Nanomaterials often undergo unusual mechanical deformations compared to their bulk counterparts when irradiated with ion-beams. This study visualizes and investigates some of the unusual interactions that can occur in nanomaterials during irradiation with medium-energy ion-beams using a Helium-Ion-Microscope (HIM). Ion-beam sculpting of semiconductor nanowires (NWs) with sub-10 nm features is demonstrated. Moreover, irradiation-induced growth of NWs at room-temperature is discovered. The new concept and possible mechanism of irradiation-induced VLS (vapor-liquid-solid) growth of NWs is introduced. These results are the basis for further fundamental and technological developments towards manipulation and visualization of ion-matter interactions at nanoscales.

title: Molecular Characterization of The Soluble Fraction of Atmospheric Particulate Matter Obtained by Chemical Oxidation With Nitric Acid

description: The availability of information regarding the composition of ambient atmospheric particulate matter and the transformations that these compounds may undergo upon atmospheric transit is surprisingly absent. Electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry is used in this study to rapidly evaluate the composition of the water-soluble organic fraction of standard and collected atmospheric particulate matter samples, and the changes that these mixtures undergo upon oxidation with nitric acid. The standard samples include representative particulate matter collected over the course of a year in Washington, D.C. and particulate matter from the exhaust of a diesel-powered engine. The collected sample is from Norfolk, Virginia during a fire event. The ultra-high resolving power of the instrument allows for the assignment of molecular formulae for detected peaks. Visualization of spectral data for samples was achieved by plotting atomic ratios of O/C and H/C on van Krevelen diagrams, and the classification of compound types using modified aromaticity index reveals substantial changes in the overall composition of the water-soluble organic fraction of model atmospheric particulate matter samples. The transformations are indicated by significant increases in the number and amount of nitrogen-containing species and condensed aromatic compounds present within the oxidized samples. Possible means, including functionalization of existing compounds, for increase solubilization of these species into the aqueous phase are suggested. The collected atmospheric particulate matter sample shows an unexpected lack of transformation in the overall molecular character upon oxidation, and may be attributed to insufficient sample size and concentration. Fourier transform ion cyclotron resonance mass spectrometry readily provides detailed information about the molecular composition of the water-soluble fraction of atmospheric particulate matter before and after nitric acid oxidation.

description: We extend the two-dimensional model of drug use introduced in Behrens et al. [1999, 2000, 2002] by introducing two additional states that model in more detail newly initiated (“light”) users’ response to the drug experience. Those who dislike the drug quickly “quit” and briefly suppress initiation by others. Those who like the drug progress to ongoing (“moderate”) use, from which they may or may not escalate to “heavy” or dependent use. Initiation is spread contagiously by light and moderate users, but is moderated by the drug’s reputation, which is a function of the number of unhappy users (recent quitters + heavy users). The model reproduces recent prevalence data from the U.S. cocaine epidemic reasonably well, with one pronounced peak followed by decay toward a steady state. However, minor variation in parameter values yields both long-run periodicity with a period akin to the gap between the first U.S. cocaine epidemic (peak ~1910) and the current one (peak ~1980), as well as short-run periodicity akin to that observed in data on youthful use for a variety of substances. The combination of short- and long-run periodicity is reminiscent of the elliptical burstors described by Rubin and Terman [2002]. The existence of such complex behavior including cycles, quasi periodic solutions, and chaos is proven by means of bifurcation analysis.

description: INTRODUCTION: Clostridium difficile infection (CDI) is currently considered the most common cause of health care-associated infections. The aim is to describe the trend of CDI in an Italian hospital and to assess the efficacy of the measures adopted to manage the burden. METHODS: we looked at CDI from 2016 to 2018. The incidence rate of CDIs was calculated as the number of new infected persons per month by the overall length of stay (incidence per 10,000 patient-days). Changes in the CDI rate during the period considered were analysed using a joinpoint regression model. RESULTS: thanks to the monitoring activity it was possible to adopt a new protocol, in order to manage CDI: the CDI episodes decreased from 85 in 2017 to 31 in 2018 (63% decrease). The joinpoint regression model was a useful tool to identify an important decrement during 2017, statistically significant (slope=-15.84; p= 0.012). CONCLUSIONS: reports based on routine laboratory data can accurately measure population burden of CDI with limited surveillance resources. This acitivity can help target prevention programs and evaluate their effect.

description: We consider a formulation of local special geometry in terms of Darboux special coordinates $P^I=(p^i,q_i)$, $I=1,...,2n$. A general formula for the metric is obtained which is manifestly $\mathbf{Sp}(2n,\mathbb{R})$ covariant. Unlike the rigid case the metric is not given by the Hessian of the real function $S(P)$ which is the Legendre transform of the imaginary part of the holomorphic prepotential. Rather it is given by an expression that contains $S$, its Hessian and the conjugate momenta $S_I=\frac{\partial S}{\partial P^I}$. Only in the one-dimensional case ($n=1$) is the real (two-dimensional) metric proportional to the Hessian with an appropriate conformal factor.

description: The spatio-temporal features of the velocity field of a fully-developed turbulent channel flow are investigated through the natural visibility graph (NVG) method, which is able to fully map the intrinsic structure of the time-series into complex networks. Time-series of the three velocity components, (u,v,w), are analyzed at fixed grid-points of the whole three-dimensional domain. Each time-series was mapped into a network by means of the NVG algorithm, so that each network corresponds to a grid-point of the simulation. The degree centrality, the transitivity and the here proposed mean link-length were evaluated as indicators of the global visibility, inter-visibility, and mean temporal distance among nodes, respectively. The metrics were averaged along the directions of homogeneity (x, z) of the flow, so they only depend on the wall-normal coordinate, y^+. The visibility-based networks, inheriting the flow field features, unveil key temporal properties of the turbulent time-series and their changes moving along y^+. Although intrinsically simple to be implemented, the visibility graph-based approach offers a promising and effective support to the classical methods for accurate time-series analyses of inhomogeneous turbulent flows.

description: The compound Sr$_{0.5}$Ce$_{0.5}$FBiS$_{2}$ belongs to the intensively studied family of layered BiS$_2$ superconductors. It attracts special attention because superconductivity at $T_{sc} = 2.8$ K was found to coexist with local-moment ferromagnetic order with a Curie temperature $T_C = 7.5$ K. Recently it was reported that upon replacing S by Se $T_C$ drops and ferromagnetism becomes of an itinerant nature (Thakur et al., Sci. Reports 6, 37527 (2016)). At the same time $T_{sc}$ increases and it was argued superconductivity coexists with itinerant ferromagnetism. Here we report a muon spin rotation and relaxation study ($μ$SR) conducted to investigate the coexistence of superconductivity and ferromagnetic order in Sr$_{0.5}$Ce$_{0.5}$FBiS$_{2-x}$Se$_x$ with $x=0.5$ and $1.0$. By inspecting the muon asymmetry function we find that both phases do not coexist on the microscopic scale, but occupy different sample volumes. For $x=0.5$ and $x=1.0$ we find a ferromagnetic volume fraction of $\sim \, 8 \%$ and $\sim \, 30 \%$ at $T=0.25$ K, well below $T_{C} = 3.4$ K and $T_C = 3.3$ K, respectively. For $x=1.0$ ($T_{sc} = 2.9$ K) the superconducting phase occupies the remaining sample volume ($\sim \, 70 \%$), as shown by transverse field experiments that probe the Gaussian damping due to the vortex lattice. We conclude ferromagnetism and superconductivity are macroscopically phase separated.

description: Introduction Global evidences indicate an association between improper WaSH practice and poor health outcomes. In rural area this practice is predominantly compromised due to inadequate access to safe drinking water, knowledge gaps and unhygienic socio-behavioural practices. Improper WaSH practice leads to increased vulnerability of various infections, thereby posing a challenge to health system. Methods A community based cross-sectional study was conducted among 879 participants of two villages in Tigiria block, Cuttack district, Odisha, India. Information pertaining to socio-demography, WaSH practices and self-reported morbidities were captured and analysed using SPSS v 25.0. Bi-variate analysis was done to assess the association between WaSH practices and any acute illnesses. Differences were considered statistically significant if p value was less than 0.05. Results Tube well was the main source of drinking water (49.3%) followed by dug well (46.6%). Only 7.1% of participants reported to purify drinking water and around 40% were still practicing open defecation. The prevalence of acute and chronic illnesses was 9.2% and 19.1% respectively. Major acute illnesses were respiratory diseases, diarrhoeal disorders and musculoskeletal problems, while major chronic illnesses were gastro intestinal problems, musculoskeletal problems and hypertension. After adjusting for age, gender and education, a significant odds ratio of 3.79 [CI = (1.23-11.70), p<0.05] was observed between drinking water source (surface water Vs tube well water) for acute illnesses. Conclusions: Poor WaSH practices among rural people make them vulnerable to acute and chronic morbidities. Health awareness and socio behavioural change pertaining to WaSH practices needs utmost priority to ensure better health.

Chiral Phase Transition at Finite Temperature in the Linear Sigma Model

Year: 1996
Subjects: subject: Nuclear Theory (nucl-th)

description: We study the chiral phase transition at finite temperature in the linear sigma model by employing a self-consistent Hartree approximation. This approximation is introduced by imposing self-consistency conditions on the effective meson mass equations which are derived from the finite temperature one-loop effective potential. It is shown that in the limit of vanishing pion mass, namely when the chiral symmetry is exact, the phase transition becomes a weak first order accompanying a gap in the order parameter as a function of temperature. This is caused by the long range fluctuations of meson fields whose effective masses become small in the transition region. It is shown, however, that with an explicit chiral symmetry breaking term in the Lagrangian which generates the realistic finite pion mass the transition is smoothed out irrespective of the choice of coupling strength.

description: Over the past decade, shifts in subsidized and affordable housing policy have led to a greater role for market dynamics and individual choice on the part of program participants and their new neighbors, and a greater awareness of the importance of neighborhood on family outcomes. Given these trends, there is an opportunity for innovative prescriptive planning models to assist in the design of policy related to regional housing mobility. The goal of this paper is to identify, and answer, some housing policy analytic questions with these models. The fundamental question motivating this paper is the following: over the long run, can middle-class neighborhoods absorb the numbers of low-income families who might take advantage of an expanded housing mobility policy without leading to neighborhood decline through outmigration of affluent families? Fundamental to this inquiry is the notion that a community’s “carrying capacity” is central to housing and community development planning and that parsimonious models based on the principles of dynamic control can help policymakers identify policy directions that are sensitive to the current state of the community. Answers to these strategic questions provide motivation for two complementary prescriptive planning models that can provide specific short-term policy guidance to affordable and assisted housing practitioners and researchers.

description: Brucellosis is an endemic bacterial zoonotic disease in developing countries; that is a serious public health problem in Iran. Brucellosis is a life-threatening multi-system disease in human with different clinical manifestations, complications and relapse. The incidence of brucellosis in Hamadan province, west of Iran is high. In addition, there is few reliable and population-based studies regarding relapse and complications of brucellosis in developing countries, therefore establishment of the registry system in areas with adequate occurrence of cases is needed to better understand the predictors of brucellosis relapse and complications and management of the disease. Detecting occurrence of relapse and complications over time and by geographical area provide information for further investigations and identification of health system deficiencies in the management of patients.

description: Recently by the development of the Internet and the Web, different types of social media such as web blogs become an immense source of text data. Through the processing of these data, it is possible to discover practical information about different topics, individuals opinions and a thorough understanding of the society. Therefore, applying models which can automatically extract the subjective information from the documents would be efficient and helpful. Topic modeling methods, also sentiment analysis are the most raised topics in the natural language processing and text mining fields. In this paper a new structure for joint sentiment-topic modeling based on Restricted Boltzmann Machine (RBM) which is a type of neural networks is proposed. By modifying the structure of RBM as well as appending a layer which is analogous to sentiment of text data to it, we propose a generative structure for joint sentiment topic modeling based on neutral networks. The proposed method is supervised and trained by the Contrastive Divergence algorithm. The new attached layer in the proposed model is a layer with the multinomial probability distribution which can be used in text data sentiment classification or any other supervised application. The proposed model is compared with existing models in the experiments such as evaluating as a generative model, sentiment classification, information retrieval and the corresponding results demonstrate the efficiency of the method.

description: The generalized open XXZ model at $q$ root of unity is considered. We review how associated models, such as the $q$ harmonic oscillator, and the lattice sine-Gordon and Liouville models are obtained. Explicit expressions of the local Hamiltonian of the spin ${1 \over 2}$ XXZ spin chain coupled to dynamical degrees of freedom at the one end of the chain are provided. Furthermore, the boundary non-local charges are given for the lattice sine Gordon model and the $q$ harmonic oscillator with open boundaries. We then identify the spectrum and the corresponding Bethe states, of the XXZ and the q harmonic oscillator in the cyclic representation with special non diagonal boundary conditions. Moreover, the spectrum and Bethe states of the lattice versions of the sine-Gordon and Liouville models with open diagonal boundaries is examined. The role of the conserved quantities (boundary non-local charges) in the derivation of the spectrum is also discussed.

description: Objective. To describe the outbreak of Clostridioides difficile infection (CDI), and the impact of the prevention and control measures that were implemented in the “Hospital Juárez de México” (HJM) for its control. Study design. A cross-sectional, descriptive, observational, and retrospective study was designed. Methods. Information on the hospital outbreak and on health care-associated infections (HCAI) was obtained from the files of the Hospital Epidemiological Surveillance Unit (HESU) of the HJM. Results. A total of 15 cases of CDI were detected from February 20th to May 22nd, 2018, which represented 55.6% and 44.4% for the male and female gender, respectively, with an average age of 56 years and a range of 24 to 86 years old. It was possible to identify six failures and deficiencies that involved health personnel and hospital logistics through analyses based on the situational diagnosis in the services involved and through the construction of cause-effect diagrams. Additionally, through the detection of the outbreak by means of laboratory tests and timeline, the HESU team implemented measures and prospective surveillance to control and prevent the emergence of new cases. Conclusions. The implementation of basic quality tools, control measures, and the prospective epidemiological surveillance had a positive impact on the control against the outbreak of C. difficile producing toxin B.

description: Let $G$ be a simple graph with $n$ vertices and let $$C(G;x)=\sum_{k=0}^n(-1)^{n-k}c(G,k)x^k$$ denote the Laplacian characteristic polynomial of $G$. Then if the size $|E(G)|$ is large compared to the maximum degree $Δ(G)$, Laplacian coefficients $c(G,k)$ are approximately normally distributed (by central and local limit theorems). We show that Laplacian coefficients of the paths, the cycles, the stars, the wheels and regular graphs of degree $d$ are approximately normally distributed respectively. We also point out that Laplacian coefficients of the complete graphs and the complete bipartite graphs are approximately Poisson distributed respectively.

description: We investigate the effect of the electric formfactor on dilepton production off pp-collisions. In the model we use, the formfactor is separated in a pion-cloud contribution and a Vector Meson Dominance part. We find that the dilepton spectrum is hardly affected by the pion-cloud part, but significantly by the VMD contribution. We point out that data with sufficient resolution would provide a crucial test of the validity of VMD for the nucleon formfactor in the timelike region.

description: The Australian heroin “drought” was a singular event deserving of the considerable scholarly attention it has engendered. The best way to understand market disruption is to examine both supply and demand side indicators, yet data on the former have been relatively neglected. Here we explore a rich data set on heroin and methamphetamine purity from 1998-2002 in Victoria that support monthly and even fortnightly time series. These series show that the drought was characterized by abrupt and substantial declines in heroin purity (from ~40% to as low as 10-15%), but those steep declines followed an extended period of substantial erosion in purity (from 70-75% in early 1999 to ~40% by the end of 2000). Purity rebounded from its post-drought lows but far from completely, stabilizing at ~20% for 2002. The heroin purity declines do not appear to stem from “cutting” at lower market levels. The declines did increase the purity variability per pure unit of heroin. There was no comparable evidence of contemporaneous effects in the methamphetamine purity series.

description: We derive a method for inverting emission line profiles formed in supernova ejecta. The derivation assumes spherical symmetry and homologous expansion (i.e., $v(r) \propto r$), is analytic, and even takes account of occultation by a pseudo-photosphere. Previous inversion methods have been developed which are restricted to optically thin lines, but the particular case of homologous expansion permits an analytic result for lines of {\it arbitrary} optical depth. In fact, we show that the quantity that is generically retrieved is the run of line intensity $I_λ$ with radius in the ejecta. This result is quite general, and so could be applied to resonance lines, recombination lines, etc. As a specific example, we show how to derive the run of (Sobolev) optical depth $τ_λ$ with radius in the case of a pure resonance scattering emission line.

description: A major challenge in Structural Health Monitoring (SHM) is to accurately identify both the location and severity of damage using the dynamic response information acquired. While in theory the vibration-based and impedance-based methods may facilitate damage identification with the assistance of a credible baseline finite element model since the changes of stationary wave responses are used in these methods, the response information is generally limited and the measurements may be heterogeneous, making an inverse analysis using sensitivity matrix difficult. Aiming at fundamental advancement, in this research we cast the damage identification problem into an optimization problem where possible changes of finite element properties due to damage occurrence are treated as unknowns. We employ the multiple damage location assurance criterion (MDLAC), which characterizes the relation between measurements and predictions (under sampled elemental property changes), as the vector-form objective function. We then develop an enhanced, multi-objective version of the DIRECT approach to solve the optimization problem. The underlying idea of the multi-objective DIRECT approach is to branch and bound the unknown parametric space to converge to a set of optimal solutions. A new sampling scheme is established, which significantly increases the efficiency in minimizing the error between measurements and predictions. The enhanced DIRECT algorithm is particularly suitable to solving for unknowns that are sparse, as in practical situations structural damage affect only a small number of finite elements. A number of test cases using vibration response information are executed to demonstrate the effectiveness of the new approach.

description: Non-asymptotic exponential upper bounds for the deviation probability for a sum of independent random fields are obtained under Bernstein's condition and assumptions formulated in terms of Kolmogorov's metric entropy. These estimations are constructive in the sense that all the constants involved are given explicitly. In the case of moderately large deviations, the upper bounds have optimal log-asymptotices. The exponential estimations are extended to the local and global continuity modulus for sums of independent samples of a random field.

ORIGINAL DESCRIPTION: 1869a: 13.
 TYPE LOCALITY: “ France ” (Macquart 1835: 428) [locality for Dorycera graminum (Fabricius, 1794) sensu Macquart (1835); “ in montuosis alpinis Insubriae et Pedemontii [alpine mountains of Insubria (= Lombardy) and Piedmont (Italy)]” (Rondani, 1869a: 13] [type locality for Macheirocera grandis Rondani, 1869].
 TYPE MATERIAL: 1 ♂, lectotype (partially eaten by dermestids) (MZUF: Box 30): Macheirocera Rndn. / grandis Rndn., Insub. [= Insubria], Pedem. [= Piedmont] / 1588 / Lectotypus Macheirocera grandis Rond., ♂, desig. Á. Soós, 1978 / Dorycera grandis Rond., ♂, det. Á. Soós, 1978.
 PARALECTOTYPES EXAMINED: 1 ♂ (covered by mold, missing head) (MZUF: Box 30): Macheirocera Rndn. / grandis Rndn., Insub. [= Insubria], Pedem.

 PARALECTOTYPES NOT EXAMINED: 1 specimen (sex not determinable, completely covered with mold) (MHNL: Box 3): [white label] / D. graminum F. / g. Dorycera.
 CURRENT STATUS: valid species, as Dorycera grandis (Soós 1984c: 46, Belcari et al. 1995b: 5).
 REMARKS: Rondani (1869a: 13) proposed Macheirocera grandis for Dorycera graminum (Fabricius, 1794) sensu Macquart (1835: 428), which he considered a new species. Rondani referred to Macquart’s redescription of Dorycera graminum, which was based on an unspecified number of specimens, and to an unspecified number of specimens of both sexes received from G. De Cristoforis, G. Mussino and L. Bellardi. Therefore, the type material should be in the collections of Macquart (MNHN, MHNL, OUMNH) and Rondani. Soós (1983: 253) designated a lectotype (♂) and paralectotypes (1 ♂, 2 ♀♀) but did not mention an additional specimen in the MHNL (this additional specimen is a paralectotype). No specimen under the name Dorycera graminum is present in either the MNHN (Muséum national d’Histoire naturelle 2020) or OUMNH (Z. Simmons, pers. comm., 2019).

title: Development of digital PCR DNA methylation assays for blood plasma-based diagnosis of lung cancer
Creators: name: Brown, Benjamin RB
Publisher: name: University of Liverpool Repository

description: Lung cancer is the leading cause of cancer-related death and is usually diagnosed at advanced stage leading to poor patient survival. Therefore there is a pressing need for early detection of disease. DNA methylation is an early event in carcinogenesis and a limited number of diagnostic markers have been developed for clinical use. This thesis seeks to address whether the development and application of novel DNA methylation assays can diagnose lung cancer at early stage. Previously identified DNA methylation biomarkers, along with novel targets identified by methylation microarray, were developed in multiplex assay format. Twelve markers were used to screen 417 bronchoalveolar lavage specimens from Liverpool Lung Project (LLP) subjects divided into training and validation sets. The optimal biomarker panel (CDKN2A, RARB and TERT) demonstrated improved clinical sensitivity and specificity (Sensitivity/Specificity: 85.7%/93.8%, AUC: 0.91) compared to previous studies. The optimal methylation algorithm detected more than 60% of stage T1 tumours and 93 cytologically occult lung cancer cases. Eight methylated DNA assays were optimised for use with the newly developed Droplet Digital™ PCR (ddPCR) platform and a targeted pre-amplification technique, MethPlex enrichment, was developed. I established a comprehensive analytical framework to compare performance of methylation-specific ddPCR and quantitative methylation-specific PCR directly and in combination with MethPlex enrichment. ddPCR demonstrated greater precision and linearity, lower limit of detection (WT1 MethPlex ddPCR LOD95 = 1.86 GE), and discriminated twofold differences in methylated DNA input. MethPlex ddPCR detected DNA methylation more frequently in lung cancer patient plasma than in controls in a retrospective case-control study. Technical methylation controls were consistently and precisely detected at inputs as low as 3 methylated copies. Discriminatory efficiency of marker combinations was inadequate, presumably due to limitations in DNA extraction methodology. DNA methylation biomarker diagnostic performance in bronchoalveolar lavage merits further validation in a prospective trial. MethPlex ddPCR analysis showed great promise, demonstrating highly sensitive DNA methylation detection in technical assessment. It is expected that appropriate DNA extraction procedures and higher cfDNA yields will lead to much improved clinical discriminatory efficiency.

description: We analyze and compare the efficiency and accuracy of two simulation methods for homogeneous random fields with multiscale resolution. We consider in particular the Fourier-wavelet method and three variants of the Randomization method: (A) without any stratified sampling of wavenumber space, (B) with stratified sampling of wavenumbers with equal energy subdivision, (C) stratified sampling with a logarithmically uniform subdivision. We focus on fractal Gaussian random fields with Kolmogorov-type spectra. As noted in previous work [3,6], variants (A) and (B) of the Randomization method are only able to generate a self-similar structure function over three to four decades with reasonable computational effort. By contrast, variant (C), suggested by [34,22], along with the Fourier-wavelet method developed by [6], is able to reproduce accurate self-similar scaling of the structure function over a number of decades increasing linearly with computational effort (for our examples we will show that nine decades can be reproduced). We provide some conceptual and numerical comparison of the various cost contributions to each random field simulation method (overhead, cost per realization, cost per evaluation). When evaluating ensemble averaged quantities like the correlation and structure functions, as well as some multi-point statistical characteristics, the Randomization method can provide good accuracy with considerably less cost than the Fourier-wavelet method. The Fourier-wavelet method, however, has better ergodic properties, and hence becomes more efficient for the computation of spatial (rather than ensemble) averages which may be important in simulating the solutions to partial differential equations with random field coefficients.
