Clinical gestalt to diagnose pneumonia, sinusitis, and pharyngitis: a meta-analysis
Authors: Dale Ariella P , Marchello Christian , Ebell Mark H
Published: June 2019

Background

The overall clinical impression (‘clinical gestalt’) is widely used for diagnosis but its accuracy has not been systematically studied.

Aim

To determine the accuracy of clinical gestalt for the diagnosis of community-acquired pneumonia (CAP), acute rhinosinusitis (ARS), acute bacterial rhinosinusitis (ABRS), and streptococcal pharyngitis, and to contrast it with the accuracy of clinical decision rules (CDRs).

Design and setting

Systematic review and meta-analysis of outpatient diagnostic accuracy studies in ambulatory care.

Method

PubMed and Google were searched for studies in outpatients that reported sufficient data to calculate accuracy of the overall clinical impression and that used the same reference standard. Study quality was assessed using Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2), and measures of accuracy calculated using bivariate meta-analysis.

Results

The authors identified 16 studies that met the inclusion criteria. The summary estimates for the positive (LR+) and negative likelihood ratios (LR−) were LR+ 7.7, 95% confidence interval (CI) = 4.8 to 11.5, and LR− 0.54, 95% CI = 0.42 to 0.65 for CAP in adults, LR+ 2.7, 95% CI = 1.1 to 4.3 and LR− 0.63, 95% CI = 0.20 to 0.98 for CAP in children, LR+ 3.0, 95% CI = 2.1 to 4.4 and LR− 0.37, 95% CI = 0.29 to 0.46 for ARS in adults, LR+ 3.9, 95% CI = 2.4 to 5.9 and LR− 0.33, 95% CI = 0.20 to 0.50 for ABRS in adults, and LR+ 2.1, 95% CI = 1.6 to 2.8 and LR− 0.47, 95% CI = 0.36 to 0.60 for streptococcal pharyngitis in adults and children. The diagnostic odds ratios were highest for CAP in adults (14.2, 95% CI = 9.0 to 21.0), ARS in adults (8.3, 95% CI = 4.9 to 13.1), and ABRS in adults (13.0, 95% CI = 5.0 to 27.0), as were the C-statistics (0.80, 0.77, and 0.84 respectively).

Conclusion

The accuracy of the overall clinical impression compares favourably with the accuracy of CDRs. Studies of diagnostic accuracy should routinely include the overall clinical impression in addition to individual signs and symptoms, and research is needed to optimise its teaching.

Published: June 2019

Induction furnaces of industrial frequency are often used at industrial enterprises for melting ferrous and non-ferrous metals and their alloys, for overheating them before casting. The resistance of the electric furnace is inductive. The total power of the induction installation includes an active component and reactive component, where the reactive power is an adjustable electrical parameter. During the melting of metals, the active-inductive load of the induction installation changes and the value of its power factor reaches 0.3. Compensation of reactive power at the input of induction furnaces inductor leads to a significant decrease in the installed power of the electric furnace transformer controlled under the load, energy losses and the cross section of cable lines. Batteries of electric capacitors are usually used as transverse compensation devices. A scheme and fuzzy algorithm for regulating the reactive power of an induction furnace of industrial frequency based on fuzzy logic are developed. The study of the fuzzy controller operation for reactive power compensation of induction furnaces of industrial frequency based on the Mamdani’s method shows that the fuzzy algorithm better maintains a given amount and direction of reactive power at the connection point of the induction furnace inductor to an electric furnace transformer. Fuzzy controller responds faster to changes in reactive power.

Published: June 2019

The article deals with the issues related to the assessment of the technical condition of structural elements, taking into account the stages of engineering research, design and installation. The importance of the topic under consideration is due to a large number of accidents at civil and industrial facilities that occur before the exhaustion of the bearing capacity. The analysis of the object (the metal frame of industrial buildings) is carried out on the basis of project documentation, data obtained by a full-scale survey, visual and instrumental control, numerical methods of research. The qualitative and quantitative parameters of the capital construction object necessary for assessing the technical condition are presented. They include design schemes of frame structures, materials, their characteristics, defects and parameters. The study shows the importance of comprehensive assessment of capital construction facilities in terms of constructive safety. Identification of errors at each stage of construction allows to prevent emergencies that lead to the destruction of the load-bearing system and to develop measures to establish the possibility (impossibility) of repair or reconstruction

Dans la vie quotidienne, les QR codes sont largement utilisés pour partager et diffuser de l’information. Peu d’études rapportent toutefois des effets de leurs usages dans un contexte de formation pour réguler l’apprentissage. Dans cette contribution, nous nous intéressons à l’effet de relances (prompts) proposées par les QR codes dans un manuel d’éveil historique en version papier intégrant des éléments de réalité augmentée. À partir d’un plan expérimental, les résultats de notre étude, réalisée dans une classe d’école fondamentale, tendent à montrer que les élèves qui bénéficient de relances par les QR Codes pour guider leur recherche et leur traitement d’informations progressent davantage dans la maîtrise du contenu traité. Il ressort également que ce sont les apprenants les plus avancés dans l’apprentissage au départ qui les ont les plus utilisés. Par ailleurs, l’analyse des résultats indique que les prompts ont également un impact significatif sur la performance en cours d’apprentissage.

Ebed Yahweh merupakan topik  yang jarang sekali di singgung dalam pembahasan-pembahasan Kristologi dewasa ini. Mungkin hal ini terjadi di karenakan istilah Ebed Yahweh tidak di temukan dalam Kitab Perjanjian Baru. Istilah Ebed Yahweh hanya dapat ditemukan penggunaannya dalam Perjanjian Lama. Para ahli sering menyelidiki arti dari sosok ebed Yahweh sebagai masalah Perjanjian Lama ,  tetapi jarang penerapannya pada Yesus. Namun demikian bukanlah berarti Perjanjian Baru sama sekali tidak membahas mengenai ebed Yahweh. Jika diselidiki dengan seksama, secara implisit penggunaan filosofi ebed Yahweh sangatlah mudah ditemui dalam pembahasan mengenai Yesus. Yesus sering sekali digambarkan sebagai Ebed Yahweh. Yesus adalah ebed Yahweh yang dijanjikan dalam Perjanjian Lama.

Feed manufacturing and human food production are the main routes of use for agricultural products. The food industryparticularly has intensively implemented the recent quality management principles and developed systems that facilitate the continuous improvement and efficiency of the industrial production. Feed production has taken similar approaches however the intensity of deployment at the manufacturer and the rollout towards its supply chain has shown slower progress. The methods, that the feed manufacturer manages the supplier chain of mainly primer agricultural products according to, have a certain impact on the efficiency of the inbound operations, feed product quality and its consistency as well as on other resources. These methods have been built on sound quality management principles that are stated not only in quality standards but also in relevant regulations. Current study addresses the questions related to the link between supply chain quality management and feed product. The objective of the frontier research was to highlight the  theoretical possibilities and benefits of the robust design methodimplemented into animal feed manufacturing dealing with highly variable ingredients.

Minat masyarakat yang tinggi tidak diberagengi dengan ketersediaan dan kecakapan dari pemandu dalam menjelaskan setiap koleksi museum kepada pengunjung. Sebagai satu-satunya museum di Provinsi Riau,sehingga masyarakat ingin mengetahui koleksi museum yang tersedia, namun karena jarak geograpis dari kabupaten ke Pekanbaru cukup jauh, umumnya masyarakat mengandalkan sumber tertulis dan elektronik sebagai sumber sekunder. Maka dalam penelitian ini peneliti merancang website dengan menerapkan WebGL sebagai fasilitas pendukung untuk merender grafis interaktif berbasis 3D dan grafis 2D pada web browser. WebGl memiliki konten canvas dari sebuah elemen HTML yang berfungsi untuk melakukan pemanggilan data dalam bentuk objek 3D. Penerapan WebGL ini, sistem yang dihasilkan akan memberikan kemudahan dalam menyebarkan informasi dan mereprestasikan benda-benda bersejarah dan informasi yang terdapat pada museum. Selain itu, masyarakat juga dapat melihat benda-benda bersejarah dalam bentuk 3D. Hal ini tentunya menjadi nilai tambah pada website yang dibangun untuk dapat menarik minat masyarakat, karena saat ini masih banyak developer yang membangun website dengan tampilan yang berorientasi pada objek 2D. Kondisi ini didukung dari hasil penelitian membuktikan bahwa 60% masyarakat dapat memperoleh informasi yang akurat setelah media website ini tersedia.

In the conditions of progress of modern medicine
in the field of surgery, antibacterial therapy and preventive practices, postoperative sternomediastinal infections still remain a pressing public health problem.
They have a significant impact on the survival rate,
duration of hospitalization and the economic burden
of treating cardiac patients. The problem of postoperative complications in cardiac surgery is very relevant at
present, given the increase in the number of geriatric
patients, patients with overweight and diabetes .
Median sternotomy, as a surgical approach, has
several disadvantages, one of which is the risk of developing infectious complications in the field of surgical
intervention. They proceed with the formation of a
superficial or deep wound infection, diastasis and fragmentation of the sternum, destabilization of the bone

Efficient resolution of racemic crown-shaped cyclotriveratrylene derivatives and isolation and characterization of the intermediate saddle isomer
Authors: Götz Sven , Schneider Andreas , Lützen Arne
Published: June 2019

The preparative resolution of a trifunctionalized C3-symmetrical chiral cyclotriveratrylene derivative was achieved via high-performance liquid chromatography (HPLC) on a chiral stationary phase. This approach is a promising alternative to the previously reported resolution through formation of diastereomeric esters because it involves fewer synthetic steps and is less prone to thermal (re)racemization. During these studies an intermediate saddle conformer could also be isolated and characterized by 1H and 13C NMR spectroscopy. The HPLC separation method was further developed in order to allow investigations on the racemization behavior of the cyclotriveratrylene derivative.

NASA’s Transiting Exoplanet Survey Satellite (TESS) presents us with an unprecedented volume of space-based photometric observations that must be analyzed in an efficient and unbiased manner. With at least ∼1,000,000 new light curves generated every month from full-frame images alone, automated planet candidate identification has become an attractive alternative to human vetting. Here we present a deep learning model capable of performing triage and vetting on TESS candidates. Our model is modified from an existing neural network designed to automatically classify Kepler candidates, and is the first neural network to be trained and tested on real TESS data. In triage mode, our model can distinguish transit-like signals (planet candidates and eclipsing binaries) from stellar variability and instrumental noise with an average precision (the weighted mean of precisions over all classification thresholds) of 97.0% and an accuracy of 97.4%. In vetting mode, the model is trained to identify only planet candidates with the help of newly added scientific domain knowledge, and achieves an average precision of 69.3% and an accuracy of 97.8%. We apply our model on new data from Sector 6, and present 288 new signals that received the highest scores in triage and vetting and were also identified as planet candidates by human vetters. We also provide a homogeneously classified set of TESS candidates suitable for future training.
The Case for a Large-scale Occultation Network
Authors: Rice Malena , Laughlin Gregory
Published: June 2019

We discuss the feasibility of and present initial designs and approximate cost estimates for a large (N ∼ 2000) network of small photometric telescopes that is purpose-built to monitor V ≲ 15 Gaia mission program stars for occultations by minor solar system bodies. The implementation of this network would permit measurement of the solar system’s tidal gravity field to high precision, thereby revealing the existence of distant trans-Neptunian objects such as the proposed “Planet Nine.” As a detailed example of the network capabilities, we investigate how occultations by Jovian Trojans can be monitored to track the accumulation of gravitational perturbations, thereby constraining the presence of undetected massive solar system bodies. We also show that the tidal influence of Planet Nine can be discerned from that of smaller, nearer objects in the Kuiper Belt. Moreover, ephemerides for all small solar system bodies observed in occultation could be significantly improved using this network, thereby improving spacecraft navigation and refining solar system modeling. Finally, occultation monitoring would generate direct measurements of size distributions for asteroid populations, permitting a better understanding of their origins.

Published: June 2019

Recent progress in three-dimensional modeling of supernovae (SNe) has shown the importance of asymmetries in the explosion. This calls for a reconsideration of the modeling of the subsequent phase, the supernova remnant (SNR), which has commonly relied on simplified ejecta models. In this paper, we bridge SN and SNR studies by using the output of an SN simulation as the input of an SNR simulation carried on for 500 yr. We consider the case of a thermonuclear explosion of a carbon–oxygen white dwarf star as a model for an SN Ia; specifically, we use the N100 delayed detonation model of Seitenzahl et al. In order to analyze the morphology of the SNR, we locate the three discontinuities that delineate the shell of shocked matter: the forward shock, the contact discontinuity, and the reverse shock, and we decompose their radial variations as a function of angular scale and time. Assuming a uniform ambient medium, we find that the impact of the SN on the SNR may still be visible after hundreds of years. Previous 3D simulations aiming to reproduce Tycho’s SNR, which started out from spherically symmetric initial conditions, failed to reproduce structures at the largest angular scales observed in X-rays. Our new simulations strongly suggest that the missing ingredient was the initial asymmetries from the SN itself. With this work, we establish a way of assessing the viability of SN models based on the resulting morphology of the SNR.
On the Orbital Decay of Globular Clusters in NGC 1052-DF2: Testing a Baryon-only Mass Model
Authors: Dutta Chowdhury Dhruba , van den Bosch Frank C. , van Dokkum Pieter
Published: June 2019

The dark matter content of the ultra-diffuse galaxy NGC 1052-DF2, as inferred from globular cluster (GC) and stellar kinematics, carries a considerable amount of uncertainty, with current constraints also allowing for the complete absence of dark matter. We test the viability of such a scenario by examining whether in a “baryon-only” mass model the observed GC population experiences rapid orbital decay due to dynamical friction. Using a suite of 50 multi-GC N-body simulations that match observational constraints on both the stellar component of NGC 1052-DF2 and its GC population but differ in the initial line-of-sight positions and the tangential velocities of the GCs, we show that there is a substantial amount of realization-to-realization variance in the evolution of the GCs. Nevertheless, over ∼10 Gyr, some of the GCs experience significant orbital evolution. Others evolve less. A combination of reduced dynamical friction in the galaxy core and GC–GC scattering keeps the GCs afloat, preventing them from sinking all the way to the galaxy center. While the current phase-space coordinates of the GCs are not unlikely for a baryon-only mass model, the GC system does evolve over time. Therefore, if NGC 1052-DF2 has no dark matter, some of its GCs must have formed farther out, and the GC system must have been somewhat more extended in the past. The presence of a low-mass cuspy halo, while allowed by the kinematics, seems improbable, as significantly shorter inspiral timescales in the central region would quickly lead to the formation of a nuclear star cluster.

CO is thought to be the main reservoir of volatile carbon in protoplanetary disks, and thus the primary initial source of carbon in the atmospheres of forming giant planets. However, recent observations of protoplanetary disks point toward low volatile carbon abundances in many systems, including at radii interior to the CO snowline. One potential explanation is that gas phase carbon is chemically reprocessed into less volatile species, which are frozen on dust grain surfaces as ice. This mechanism has the potential to change the primordial C/H ratio in the gas. However, current observations primarily probe the upper layers of the disk. It is not clear if the low volatile carbon abundances extend to the midplane, where planets form. We have run a grid of 198 chemical models, exploring how the chemical reprocessing of CO depends on disk mass, dust grain size distribution, temperature, cosmic-ray and X-ray ionization rate, and initial water abundance. Building on our previous work focusing on the warm molecular layer, here we analyze the results for our grid of models in the disk midplane at 12 au. We find that either an ISM level cosmic-ray ionization rate or the presence of UV photons due to a low dust surface density are needed to chemically reduce the midplane CO gas abundance by at least an order of magnitude within 1 Myr. In the majority of our models CO does not undergo substantial reprocessing by in situ chemistry and there is little change in the gas phase C/H and C/O ratios over the lifetime of the typical disk. However, in the small subset of disks where the disk midplane is subject to a source of ionization or photolysis, the gas phase C/O ratio increases by up to nearly 9 orders of magnitude due to conversion of CO into volatile hydrocarbons.

Published: June 2019

Understanding the relationship between the magnetic field and coronal heating is one of the central problems of solar physics. However, studies of the magnetic properties of impulsively heated loops have been rare. We present results from a study of 34 evolving coronal loops observed in the Fe xviii line component of 94 Å filter images obtained by the Atmospheric Imaging Assembly (AIA)/Solar Dynamics Observatory (SDO) from three active regions with different magnetic conditions. We show that the peak intensity per unit cross section of the loops depends on their individual magnetic and geometric properties. The intensity scales proportionally to the average field strength along the loop (B
avg) and inversely with the loop length (L) for a combined dependence of

. These loop properties are inferred from magnetic extrapolations of the photospheric Helioseismic and Magnetic Imager (HMI)/SDO line-of-sight and vector magnetic field in three approximations: potential and two nonlinear force-free (NLFF) methods. Through hydrodynamic modeling (enthalpy-based thermal evolution loop (EBTEL) model) we show that this behavior is compatible with impulsively heated loops with a volumetric heating rate that scales as

Radiative Torques of Irregular Grains: Describing the Alignment of a Grain Ensemble
Authors: Herranen Joonas , Lazarian A. , Hoang Thiem
Published: June 2019

The radiative torque (RAT) mechanism is the most promising way of explaining observed polarization arising from aligned grains. We explore the efficiency of the grain alignment by an anisotropic radiation flow for an extensive ensemble of grain shapes, grain sizes (a), and wavelength (λ). We calculate the distribution of the ratios of the amplitudes of the two major components of the RATs, which is an essential parameter that is used in the theory of RAT alignment in Lazarian & Hoang. While this distribution is different for the different classes of grain shapes that we considered, the most probable values of the parameter are centered in the range of q
max ∼ 0.5–1.5. The functional form from the calculated RATs is in good agreement with the analytical model. We find that the RAT efficiency scales as (λ/a)−2.6 for λ ≳ 1.8a, which has a slightly shallower slope than previously found in LH07. This increases the power of predictions obtained with the RAT theory. We also confirm that superparamagnetic inclusions are necessary for achieving high degrees of alignment, and constrain the parameter space describing the requirements for achieving these alignment degrees.
Differences in Faraday Rotation between Adjacent Extragalactic Radio Sources as a Probe of Cosmic Magnetic Fields
Authors: Vernstrom T. , Gaensler B. M. , Rudnick L. , Andernach H.
Published: June 2019

Faraday rotation measures (RMs) of extragalactic radio sources provide information on line-of-sight magnetic fields, including contributions from our Galaxy, source environments, and the intergalactic medium (IGM). Looking at differences in RMs, ΔRM, between adjacent sources on the sky can help isolate these different components. In this work, we classify adjacent polarized sources in the NRAO VLA Sky Survey (NVSS) as random or physical pairs. We recompute and correct the uncertainties in the NVSS RM catalog, since these were significantly overestimated. Our sample contains 317 physical and 5111 random pairs, all with Galactic latitudes

, polarization fractions ≥2%, and angular separations between 1.′5 and 20′. We find an rms ΔRM of 14.9 ± 0.4 and 4.6 ± 1.1 rad m−2 for the random and physical pairs, respectively. This means that polarized extragalactic sources that are close on the sky but at different redshifts have larger differences in RM than two components of one source. This difference of ∼10 rad m−2 is significant at 5σ and persists in different data subsamples. While there have been other statistical studies of ΔRM between adjacent polarized sources, this is the first unambiguous demonstration that some of this RM difference must be extragalactic, thereby providing a firm upper limit on the RM contribution of the IGM. If the ΔRMs originate local to the sources, then the local magnetic field difference between random sources is a factor of 2 larger than that between components of one source. Alternatively, attributing the difference in ΔRMs to the intervening IGM yields an upper limit on the IGM magnetic field strength of 40 nG.
The Lyman Continuum Escape Survey: Ionizing Radiation from [O iii]-strong Sources at a Redshift of 3.1

Published: June 2019

We present results from the LymAn Continuum Escape Survey (LACES), a Hubble Space Telescope (HST) program designed to characterize the ionizing radiation emerging from a sample of Lyα-emitting galaxies at redshift z ≃ 3.1. As many show intense [O iii] emission characteristic of z > 6.5 star-forming galaxies, they may represent valuable low-redshift analogs of galaxies in the reionization era. Using HST Wide Field Camera 3/UVIS F336W to image Lyman continuum emission, we investigate the escape fraction of ionizing photons in this sample. For 61 sources, of which 77% are spectroscopically confirmed and 53 have measures of [O iii] emission, we detect Lyman continuum leakage in 20%, a rate significantly higher than is seen in individual continuum-selected Lyman break galaxies. We estimate that there is a 98% probability that ≤2 of our detections could be affected by foreground contamination. Fitting multiband spectral energy distributions (SEDs) to take account of the varying stellar populations, dust extinctions and metallicities, we derive individual Lyman continuum escape fractions corrected for foreground intergalactic absorption. We find escape fractions of 15%–60% for individual objects and infer an average 20% escape fraction by fitting composite SEDs for our detected samples. Surprisingly, however, even a deep stack of those sources with no individual F336W detections provides a stringent upper limit on the average escape fraction of less than 0.5%. We examine various correlations with source properties and discuss the implications in the context of the popular picture that cosmic reionization is driven by such compact, low-metallicity star-forming galaxies.
