Validating and Updating GRASP: An Evidence-Based Framework for Grading and Assessment of Clinical Predictive Tools

Background: When selecting predictive tools, clinicians are challenged with an overwhelming and ever-growing number, most of which have never been implemented or evaluated for comparative effectiveness. The authors developed an evidence-based framework for grading and assessment of predictive tools (GRASP). The objective of this study is to update GRASP and evaluate its reliability.Methods: A web-based survey was developed to collect responses of a wide international group of experts, who published studies on clinical prediction tools. Experts were invited via email and their responses were quantitatively and qualitatively analysed using NVivo software. The interrater reliability of the framework, to assign grades to eight predictive tools by two independent users, was evaluated.Results: We received 81 valid responses. On five-points Likert scale, experts overall strongly agreed with GRASP evaluation criteria=4.35/5, SD=1.01, 95%CI [4.349, 4.354]. Experts strongly agreed with six criteria: predictive performance=4.88/5, SD=0.43, 95%CI [4.87, 488] and evidence levels of predictive performance=4.44/5, SD=0.87, 95%CI [4.44, 4.45], usability=4.68/5, SD=0.70, 95%CI [4.67, 4.68] and potential effect=4.62/5, SD=0.68, 95%CI [4.61, 4.62], post-implementation impact=4.78/5, SD=0.57, 95%CI [4.78, 4.79] and evidence direction=4.25/5, SD=0.78, 95%CI [4.25, 4.26]. Experts somewhat agreed with one criterion: post-implementation impact levels=4.18/5, SD=1.14, 95%CI [4.17, 4.19]. Experts were neutral about one criterion; usability is higher than potential effect=2.96/5, SD=1.23, 95%CI [2.95, 2.97]. Sixty-four respondents provided recommendations to six open-ended questions regarding updating evaluation criteria. Forty-three suggested potential effect is higher than usability. Experts highlighted the importance of quality of studies and strength of evidence. Accordingly, GRASP concept and its detailed report were updated. The framework’s interrater reliability was tested, and two independent reviewers produced accurate and consistent results in grading eight predictive tools using the framework.Conclusion: Before implementation, internal and external validation of predictive performance of tools is essential in evaluating sensitivity and specificity. During planning for implementation, potential effect is more important that usability to evaluate acceptability of tools by users. Post-implementation, it is crucial to evaluate tools’ impact on healthcare processes and clinical outcomes. The GRASP framework aims to provide clinicians with a high-level, evidence-based, and comprehensive, yet simple and feasible, approach to evaluate, compare, and select predictive tools.
On the extremal function for graph minors

For a graph H $H$ , let c(H)=inf{c:e(G)≥c|G|impliesG≻H} $c(H)=\text{inf}\{c:e(G)\ge c|G|\,\,\text{implies}\,\,G\succ H\}$ , where G≻H $G\succ H$ means that H $H$ is a minor of G $G$ . We show that if H $H$ has average degree d $d$ , then c(H)≤(0.319…+od(1))|H|logd $c(H)\le (0.319\,\ldots \,+{o}_{d}(1))|H|\sqrt{\mathrm{log}d}$ where 0.319… $0.319\ldots $ is an explicitly defined constant. This bound matches a corresponding lower bound shown to hold for almost all such H $H$ by Norin, Reed, Wood and the first author.
On the Use/Misuse of the Term 'Phoneme'

The term 'phoneme' lies at the heart of speech science and technology, and yet it is not clear that the research community fully appreciates its meaning and implications. In particular, it is suspected that many researchers use the term in a casual sense to refer to the sounds of speech, rather than as a well defined abstract concept. If true, this means that some sections of the community may be missing an opportunity to understand and exploit the implications of this important psychological phenomenon. Here we review the correct meaning of the term 'phoneme' and report the results of an investigation into its use/misuse in the accepted papers at INTERSPEECH-2018. It is confirmed that a significant proportion of the community (i) may not be aware of the critical difference between `phonetic' and 'phonemic' levels of description, (ii) may not fully understand the significance of 'phonemic contrast', and as a consequence, (iii) consistently misuse the term 'phoneme'. These findings are discussed, and recommendations are made as to how this situation might be mitigated.
COHERENT constraints after the Chicago-3 quenching factor measurement

Recently an improved quenching factor (QF) measurement for low-energy nuclear recoils in CsI[Na] has been reported in arXiv:1907.04828 [nucl-ex]. The new energy-dependent QF is characterized by a reduced systematic uncertainty and leads to a better agreement between the experimental COHERENT data and the Standard Model (SM) expectation. In this work we report updated constraints on parameters that describe the process of coherent elastic neutrino-nucleus scattering within and beyond the SM and we also present how the new QF affects their interpretation.
Space Based Gravitational Wave Astronomy Beyond LISA

The Laser Interferometer Space Antenna (LISA) will open three decades of gravitational wave (GW) spectrum between 0.1 and 100 mHz, the mHz band. This band is expected to be the richest part of the GW spectrum, in types of sources, numbers of sources, signal-to-noise ratios and discovery potential. When LISA opens the low-frequency window of the gravitational wave spectrum, around 2034, the surge of gravitational-wave astronomy will strongly compel a subsequent mission to further explore the frequency bands of the GW spectrum that can only be accessed from space. The 2020s is the time to start developing technology and studying mission concepts for a large-scale mission to be launched in the 2040s. The mission concept would then be proposed to Astro2030. Only space based missions can access the GW spectrum between 10 nHz and 1 Hz because of the Earths seismic noise. This white paper surveys the science in this band and mission concepts that could accomplish that science. The proposed small scale activity is a technology development program that would support a range of concepts and a mission concept study to choose a specific mission concept for Astro2030. In this white paper, we will refer to a generic GW mission beyond LISA as bLISA.
Simple operator formulation of the Bakamjian-Thomas approach to heavy quark current , with generalisation to HQET, and with applications to transitions of Lambda-b

Starting from the general formulation of current matrix elements in the Bakamjian-Thomas (BT) approach to quark models, certain aspects of their heavy quark limit are exhibited in an intuitive form, allowing a common treatment for any number of quarks and angular momenta j,j'. We use the general Falk interpretation of Isgur-Wise functions as overlaps of light parton states in motion. Then, in BT, for small collinear velocities, the motion of these states is described by a very simple dimensionless differential operator O acting on the internal wave functions of the light quarks, which a relativistic generalisation of the dipole operator times the quark mass : it appears as the generator of Lorentz transformations for N free light particles.
Exact Analytical Expression for the Synchrotron Radiation Spectrum in the Gaussian Turbulent Magnetic Field

We demonstrate that the exact solution for the spectrum of synchrotron radiation from an isotropic population of monoenergetic electrons in a turbulent magnetic field with a Gaussian distribution of local field strengths can be expressed in the simple analytic form: , where We use this expression to find the approximate synchrotron spectra for power-law electron distributions with -type high-energy cutoff; the resulting synchrotron spectrum has the exponential cutoff factor with a frequency raised to the 2β/(3β + 4) power in the exponent. For the power-law electron distribution without a high-energy cutoff, we find the coefficient am as a function of the power-law index, which results in the exact expression for the synchrotron spectrum when using the monochromatic (i.e., each electron radiates at the frequency ) approximation.
Programação genética paralela com Pareto: uma ferramenta para modelagem via regressão simbólica

Marques, L. G. Parallel Pareto Genetic Programming: a tool to modeling via symbolic regression. 111 p. Master Thesis – Faculty of Electrical Engineering, Federal University of Uberlândia, 2013 . Program induction involves the inductive discovery of a computer program that produces some desired output when presented with some particular input. An example is the symbolic regression, a modeling tool that seeks mathematical expressions of functions to fit a given multivariate data set, mapping input variables to output variables of control. The genetic programming, a subarea of evolutive computing that uses an analogy of Darwin’s evolutionary theory and some ideas from the genetics field, is an automatic technique for producing a computer program widely used to solve such problems. However, implementing genetic programming is not trivial for most professionals, besides demanding high computational power. This work presents a parallel implementation of genetic programming simple to handle, optimized for computers with multicore architecture, and satisfying competitive criteria of structural simplicity model and prediction accurate model, through a special multi-objective flavor of a genetic programming, called Pareto Genetic Programing. The proposed implementation has performance gains proportional to the amount of available cores in use, and has been successfully applied to several types of regression problems.
A primer on pseudoscorpions and taxonomic status in Canada

Introduction T arachnid order Pseudoscorpiones, commonly known as pseudoscorpions, false scorpions, or book scorpions, represent an important yet understudied Arachnid order. Harvey (2002) placed the order among a list of ‘neglected cousins’ of the Arachnida, in an attempt to highlight the need for more intensive research on the smaller arachnid orders. The pseudoscorpions comprise about 3.3% of the described arachnid species (Harvey 2002), with just over 3,000 known species, globally (Harvey 1990), and about 350 species are known from North America north or Mexico (Coddington et al. 1990). Although this diversity pales in comparison to many other arthropod orders, pseudoscorpions are nevertheless ecologically important, morphologically and taxonomically distinct, and efforts are required to better understand the biology, ecology, and taxonomy of these curious arachnids. In North America, despite incredible work by some arachnologists in the midto late 1900s (e.g. E. Benedict, C. Hoff, S. Nelson, W. Muchmore), we know embarrassingly little about the distribution, ecology and taxonomy of pseudoscorpions in much of the northern half of the continent. I have begun a long-term inventory of pseudoscorpions in Canada, and the first step, reported here, is to document what species are presently known to occur in the country, and to speculate on their distributions. Future efforts will be directed at producing an identification guide to pseudoscorpions of Canada, and subsequent taxonomic and ecological studies. This is especially important now, since William Muchmore, the current expert on Pseudoscorpiones in North America, has been retired for many years, and personal communications with him have indicated he has almost completely wrapped up his life’s work on this group.
Modeling noise in five dimensions : A case study from Sarukawa oil field in Japan

Located in the Akita prefecture of Japan, the Sarukawa oilfield reservoir dates back to 1958. Despite hundreds of wells drilled, several uncertainties still remain for interpreters resulting in structural risk defining the main reservoir. One of these risks include remaining uncertainties defining the complex geological structure associated with a major regional fault. The latest seismic survey conducted over the oilfield was acquired in 2003. The survey area covered a transition zone and was acquired with mixed sources. Strong noise, contaminating onshore and offshore records and sparse geometry resulted in a poor image after prestack time migration (PSTM) processing.
A Low Profile , Multi-Band Yagi Antenna with High Gain Characteristic over an EBG Ground Plane

Design of a closely spaced Yagi antenna over an electromagnetic band-gap (EBG) ground plane is suggested to achieve multi-bands with high gains. The total height from the top of the EBG ground plane to the director is 0. 03λ. The first resonance occurs due to the driver of the Yagi over the EBG ground plane (dipole mode). The second resonance is attained due to the Yagi itself (Yagi mode). The gains at dipole mode and Yagi mode are 7.84dB and 8.75dB, respectively. These multi-bands can be tuned easily by changing Yagi elements.

The Effects of Aortic Cross-Clamp and Pump Times on Oxidative Damage and Antioxidant Parameters in the Patients Undergoing Open-Heart Surgery

Background: The aim of the present study is to determine the correlation between the oxidative stress marker and the antioxidant parameters with the aortic cross clamp and pump times and to make contribution to the related studies. Methods: Fifty four elective patients for whom cardiopulmonary bypass operation was planned with different indications were included in this study. While sixteen of fifty four patients were female, thirty eight patients were male. MDA, GPx, GSH, CAT, and SOD were investigated in the blood samples. Results: When the change in oxidative damage and antioxidant parameters in preoperative, operative, and postoperative periods was examined in the present study; a statistically significant increase was observed in GSH level and CAT enzyme activity in operative and postoperative periods compared to preoperative period. In the present study, it was observed that there was no statistical difference in preoperative, operative, and postoperative periods in terms of cross-clamp period and pump times. Conclusion: There was no sufficient data regarding the efficiency of aortic cross-clamp time and especially the pump time in this oxidative damage. It is recommended to conduct comprehensive studies in order to obtain sufficient, precise and reliable data regarding its effect in the oxidative damage. Additionally, the fact that CPB triggers oxidative damage may be reduced or prevented by the studies to be conducted on antioxidant treatment in CPB with same sensitivity. Thus, inhibition of different disease complications may allow patients undergoing necessarily a CPB operation to maintain a more qualified life.
Amyotrophic Lateral Sclerosis and Frontotemporal Degeneration

Our objective was to identify whether rare genetic variation in amyotrophic lateral sclerosis (ALS) candidate survival genes modifies ALS survival. Candidate genes were selected based on evidence for modifying ALS survival. Each tail of the extreme 1.5% of survival was selected from the UK MND DNA Bank and all samples available underwent whole genome sequencing. A replication set from the Netherlands was used for validation. Sequences of candidate survival genes were extracted and variants passing quality control with a minor allele frequency 0.05 were selected for association testing. Analysis was by burden testing using SKAT. Candidate survival genes UNC13A, KIFAP3, and EPHA4 were tested for association in a UK sample comprising 25 short survivors and 25 long survivors. Results showed that only SNVs in UNC13A were associated with survival (p 1⁄4 6.57 10 ). SNV rs10419420:G4A was found exclusively in long survivors (3/25) and rs4808092:G4A exclusively in short survivors (4/25). These findings were not replicated in a Dutch sample. In conclusion, population specific rare variants of UNC13A may modulate survival in ALS.
Strategies for learning in class imbalance problems

A set of examples or training set (TS) is said to be imbalanced if one of the classes is represented by a very small number of cases compared to the other classes. Following the common practice [1,2], we consider only two-class problems and therefore, the examples are either positive or negative (that is, either from the minority class or the majority class, respectively). High imbalance occur in applications where the classi;er is to detect a rare but important case, such as fraudulent telephone calls, oil spills in satellite images, failures in a manufacturing process, or a rare medical diagnoses. It has been observed that class imbalance may cause a signi;cant deterioration in the performance attainable by standard supervised methods. Most of the attempts at dealing with this problem can be grouped into three categories [2]. One is to assign distinct costs to the classi;cation errors. The second is to resample the original TS, either by over-sampling the minority class and/or under-sampling the majority class until the classes are approximately equally represented. The third consists in internally biasing the discrimination-based process so as to compensate for the class imbalance. As pointed out by many authors, the performance of a classi;er in applications with class imbalance must not be expressed in terms of the average accuracy. For instance, consider a domain where only 2% examples are positive. In such a situation, labeling all new samples as negative would give an accuracy of 98%, but failing on all positive cases. Consequently, in environments with imbalanced

Development Of Constitutive Equations ForCreep Damage Behaviour Under Multi-axialStates Of Stress

A generic formulation for creep damage constitutive equations for multi-axial states of stress is proposed. First, the requirements of lifetime consistency and creep deformation consistency have been specified. Then two functions of states of stress were introduced to depict the influences of multi-axial states of stress on rupture lifetime and strain at failure, respectively; this is similar to that of separate yielding function and admissible function proposed and employed in the development of the generalised plasticity theory. Previous formulation and its applications are based only on lifetime consistency, and the fundamental requirement of creep deformation consistency has not been addressed, which results in incorrect prediction of creep strain and damage evolution. Furthermore, previous formulation is unable to consider the effect of mean stress on lifetime, which is controversy to general conclusion. This paper presents a theoretical development through new formulation. Its super effectiveness is demonstrated by and compared with previous formulation through predicted strain at failure and lifetime under bi-axial cases. It is further concluded that this new formulation and associated concept and methodology is generic and could be applied in the development of other damage constitutive equations.

Winter Lightning ( ISWL 2017 ) 1 Measuring Lightning Currents on Wind Turbines

This paper is dedicated to the question of measuring lightning current events on tall objects such as wind turbines. Because of their height, location at the open or uplands area, the probability of lightning strike increases significantly. Modern wind power plants with total height up to 200 m are able to trigger upward or ground-to-cloud flashes, especially during winter season, which are different from downward flashes. In general, upward lightning is critical for the air-termination system of wind turbine with regard to transferred charge, which can easily exceed the value of 300 As specified for lightning protection level I (LPL I) in the international standard IEC 62305 [1]. For proper operation and efficient maintenance regimes measurement of the lightning events on wind turbines is needed. The measuring principle, based on Rogowski coil sensors is presented in this paper. The data obtained from the measuring system allow to evaluate the effects of lightning strikes on wind turbines. Some specifics during the measuring of lightning events on tall objects are discussed as well. In particular, the peak value of lightning impulse currents, to be able to be measured, should be greater than 200 kA specified again for LPL I. Also upward lightning may have only a long duration initial continuing current (ICC-only), which is difficult to be detected by LLS and to be measured. Both of these lightning parameters have different effects on components of wind turbines, which are discussed in detail in the paper.
OBVI: Hierarchical 3D Video-Browsing

Broadcast quaIity video consists of some 100000 frames per hour. Browsing through large amounts of digital video, users need to get a quick overview of the material, in search of "intended" content. We present an approach to fast visual perception of video contents; it is based on flexible hierarchical 3D representa­tions which in turn rely on ranked key frames. This approach has led to a commerical product which can be used both for video browsing on the Web and as a visual indexing tool for dedi­cated video servers.
