High common‐mode suppression balanced bandpass filter using isosceles right‐angled triangular resonator
Authors: Zhang Qiao , Chen Chang , Chen Weidong 
Published: July 2019

A balanced bandpass filter with high common‐mode (CM) suppression using isosceles right‐angled triangular (RAT) resonator is proposed in this Letter. The two high order orthogonal modes (TM210Z and TM200Z) are generated in the two overlapped isosceles RAT resonators under differential‐mode (DM) and CM excitation, respectively. In this structure, TM210Z mode will be transmitted and TM200Z mode will be blocked. Furthermore, four via‐holes are introduced to disturb TM210Z mode while TM200Z mode is unaffected, in order to shift the DM passband to the position of CM suppression. The designed balanced bandpass filter operating at 6.12 GHz with 3 dB fractional bandwidth of 5% is fabricated and measured. The measured and simulated results match very well with each other validating the feasibility of the proposed design concept.
Slant‐range accuracy assessment for the YaoGan 13

Published: July 2019

YaoGan 13 (YG‐13) represents the most advanced Chinese synthetic aperture radar satellite currently in use. This paper reports on experiments conducted to assess the slant‐range accuracy of YG‐13. Error sources in the YG‐13 ranging system, such as atmospheric path delay and the internal electronic delay of the instrument were analysed. A real‐time atmospheric delay correction model was established to consider both tropospheric and ionospheric delays. Six corner reflectors (CRs) were set up to ensure the accuracy of validation methods. Results showed that pixel location accuracies of up to 0.427 m standard deviation could be achieved. Furthermore, adjustment of the CRs can cause a marginal loss of ranging precision. After eliminating this error, the ranging accuracy was improved to 0.162 m. For YG‐13, a single frequency GPS receiver is used and the orbital accuracy is the biggest factor restricting its slant‐range accuracy. Results show that the YG‐13 slant‐range can achieve decimetre‐level accuracy. YG‐13 provides convenience in terms of access to control points and target locations that does not depend on ground equipment.
A meta-analysis of core-collapse supernova56Ni masses
Authors: Anderson J. P. 
Published: July 2019

Context.A fundamental property determining the transient behaviour of core-collapse supernovae (CC SNe) is the amount of radioactive56Ni synthesised in the explosion. Using established methods, this is a relatively easy parameter to extract from observations.Aims.I provide a meta-analysis of all published56Ni masses for CC SNe.Methods.Collating a total of 258 literature56Ni masses, I compared distributions of the main CC SN types: SNe II, SNe IIb, SNe Ib, SNe Ic, and SNe IcBL.Results.Using these published values, I calculated a median56Ni mass of 0.032M⊙for SNe II (N = 115), 0.102M⊙for SNe IIb (N = 27), 0.163M⊙for SNe Ib (N = 33), 0.155M⊙for SNe Ic (N = 48), and 0.369M⊙for SNe IcBL (N = 32). On average, stripped-enevelope SNe (SE-SNe: IIb, Ib, Ic, and Ic-BL) have much higher values than SNe II. These observed distributions are compared to those predicted from neutrino-driven explosion models. While the SN II distribution follows model predictions, the SE-SNe have a significant fraction of events with56Ni masses much higher than predicted.Conclusions.If the majority of published56Ni masses are to be believed, these results imply significant differences in the progenitor structures and/or explosion properties between SNe II and SE-SNe. However, such distinct progenitor and explosion properties are not currently favoured in the literature. Alternatively, the popular methods used to estimate56Ni masses for SE-SNe may not be accurate. Possible issues with these methods are discussed, as are the implications of true56Ni mass differences on progenitor properties of different CC SNe.

ZusammenfassungBei den bekannten fest auf den Zähnen angebrachten Apparaturen sind in den meisten Fällen die elastischen Eigenschaften verschiedener Metalllegierungen für die Zahnauslenkungen verantwortlich. Aber auch die flexiblen Materialeigenschaften von bestimmten Kunststoffarten lassen sich zur Zahnbewegung nutzen. Seit fast 20 Jahren hat sich durch im CAD/CAM-Großserienverfahren hergestellten, thermoplastischen Polyurethan-Kunststoff-Schienen das Indikationsspektrum der Aligner-Therapie aufgrund technologischen Fortschritts der verschiedenen Aligner Hersteller und der Erfahrung der Behandler zunehmend erweitert. Unter anderem durch die Weiterentwicklung spezieller Attachments, Materialien oder der digitalen Planungssoftware kann beobachtet werden, dass bei verantwortungsvoller, korrekter Planung seitens des in dieser Technik erfahrenen Kieferorthopäden und unbedingter Compliance seitens des Patienten mittlerweile auch anspruchsvolle kieferorthopädische Behandlungen, wie die Therapie des frontal offenen oder tiefen Bisses, größtenteils vorhersagbar mit Alignern durchgeführt werden können. Hierbei bedarf es jedoch auf Basis einer umfassenden Anamnese und Diagnostik einer genauen Berücksichtigung patientenspezifischer Parameter wie u.a. Alter, möglicher Parafunktion, skelettaler Konfiguration, Parodontalzustand und Funktionsbefund durch den erfahrenen Fachzahnarzt. Dieser muss unter Wahrung der bekannten biomechanischen Prinzipien die Anwendung der modernen softwaregestützten Applikationen so zu nutzen wissen, dass aus einer virtuellen Computersimulation eine realistische, klinische Umsetzung resultiert. Anhand von Fallbeispielen werden exemplarisch die Chancen und Grenzen der Aligner-Therapie aufgezeigt, die zur Korrektur der vertikalen Dimension gegeben sind.

Molaren-Inzisiven-Hypomineralisation – Prävalenz, Ätiologie und Therapie
Authors: Bekes Katrin 
Published: July 2019

ZusammenfassungMolaren-Inzisiven-Hypomineralisation (MIH) ist ein weltweit verbreitetes Problem. Die Ausprägung hypomineralisierter Zahndefekte und die daraus resultierende Problematik können jedoch stark differieren. Zähne welche bereits kurz nach dem Durchbruch stark zerstört und dazu noch hypersensibel sind, erfordern andere Therapiepläne als nur leicht verfärbte, aber eigentlich gesunde Zähne. Eine frühzeitige Erkennung des Krankheitsbildes, die umfassende Betreuung und die Einleitung notwendiger therapeutischer Maßnahmen sind essenziell, um progressiven Schmelzverlusten entgegenzuwirken und einen langfristigen Zahnerhalt zu ermöglichen.Der vorliegende Beitrag soll einen Einblick in die rezente Ätiologie, die Diagnostik und die therapeutischen Möglichkeiten der MIH geben und eine Hilfestellung für die Praxis sein.

Published: July 2019

ZusammenfassungFür homöopathische Komplexmittel existiert, trotz fast 100-jähriger
Verordnungspraxis, nur wenig allgemeingültige Lehrbuchliteratur. Ebenso wird
kaum unabhängige Forschung betrieben. Um das Erkenntnismaterial zur
Verordnungspraxis zu erweitern, wurde unter dem Dach der Arzneimittel-Hersteller
eine Therapeutenbefragung zur Verordnungs- und Dosierungspraxis sowie zum
Auftreten von homöopathischen Erstverschlimmerungen und
Arzneimittelprüfsymptomen durchgeführt. Insgesamt konnten von 513 Fragebögen 504
ausgewertet werden. Als ein wichtiges Ergebnis zeigte sich, dass nur wenige
Therapeuten den strikten Dosierungsempfehlungen der Packungsbeilage folgen,
sondern nach individuellen Behandlungsschemata bzw. patientenspezifischen
Kriterien verordnen. Wünschenswert wäre daher, die von den Zulassungsbehörden
vorgegebenen Dosierungsangaben in der Packungsbeilage zu erweitern und die
Patienten über die Möglichkeit der individuellen Dosierung zu informieren, um
die Anwendung in der Praxis besser wiederzugeben.

ZusammenfassungDie Ende 2015 veröffentlichten ESC/ERS-Leitlinien und andere internationale Empfehlungen definierten die pulmonale Hypertonie (PH) bisher durch einen invasiv gemessenen mittleren pulmonal arteriellen Druck (mPAP) ≥ 25 mmHg in Ruhe. Auf dem 6th World Symposium on Pulmonary Hypertension in Nizza wurde eine Modifikation dieser hämodynamischen Definition im Sinne einer Senkung des Schwellenwertes auf > 20 mmHg vorgeschlagen. Für die präkapilläre PH wird zusätzlich ein pulmonaler Gefäßwiderstand (PVR) ≥ 3 Wood-Einheiten (WE) gefordert. Diese Änderung muss im Hinblick auf die zugrunde liegende Rationale und mögliche Konsequenzen kritisch hinterfragt werden; es bedarf daher einer eingehenden Erläuterung. Insbesondere muss klargestellt werden, dass diese Änderung aktuell keinen Einfluss auf die evidenzbasierte und zulassungskonforme Verschreibung von Medikamenten zur gezielten Therapie der pulmonal arteriellen Hypertonie (PAH) hat.
Acute Pulmonary Embolism: Contemporary Approach to Diagnosis, Risk-Stratification, and Management
Authors: Tak Tahir , Karturi Swetha , Sharma Umesh , Eckstein Lee , Poterucha Joseph T. , Sandoval Yader 
Published: July 2019

AbstractPulmonary embolism (PE) affects over 300,000 individuals each year in the United States and is associated with substantial morbidity and mortality. Improvements in the diagnostic performance and availability of computed tomographic pulmonary angiography and D-dimer testing have facilitated the evaluation of patients with suspected PE. High clinical suspicion is required in those with risk factors and/or those that manifest signs or symptoms of venous thromboembolic disease, with validated clinical risk scores such as the Wells and modified Wells score or the PE rule-out criteria helpful in estimating the likelihood for PE. For those with confirmed PE, patients should be categorized and triaged according to the presence or absence of shock or hypotension. Normotensive patients can be further risk-stratified using validated prognostic risk scores, as well as by using imaging and cardiac biomarkers, with those having either signs of right ventricular dysfunction on imaging studies and/or abnormal cardiac biomarkers categorized as being at intermediate-risk and requiring close monitoring and hospital admission. Early discharge and/or home therapy are possible in those that do not manifest any high-risk features. The initial treatment for most patients that are stable consists of anticoagulation, with advanced therapies such as thrombolysis, catheter-based therapies, or surgical embolectomy deferred for those at high risk. Given the heterogeneous presentations of PE and various management strategies available, the development of multidisciplinary PE response teams has emerged to help facilitate decision-making in these patients.
Why Trump won the elections
Authors: Violi Patrizia 
Published: July 2019

Abstract
In this article I would like to focus on the dialogical transformations that the use of social media has introduced into political discourse, showing why they have an increasing relevance on the whole landscape of our contemporary political arena. In order to do that, I will analyse their semiotic functioning, and the way in which they have transformed the traditional dialogical structure, still present in other forms of technologically mediated communication. Finally, I will advance some hypothesis on how these transformations can favour the growth of populism, a phenomenon that should concern anybody interested in dialogue, since populism represents precisely the death of any form of dialogue.
Decision announcements in small claims court
Authors: Tracy Karen , Craig Robert T. 
Published: July 2019

Abstract
This study analyzes judges’ decision announcements at the end of small claims hearings when the
judge informs the parties who has won. Background on US small claims courts is provided, and the data and
grounded practical theory, the analytic approach, are described. Then, we overview the small claims decision
announcement genre, describe key areas of variation among judges, and identify and explicate a recurring
problem built into the design of small claims proceedings. Cases that pit what is legally correct against what
commonsense fairness dictates can be troublesome for judges and this trouble is marked discursively in judge
announcements. The paper concludes by describing the challenge this raises for the development of grounded
practical theory.
Names and the transidioma
Authors: Jacquemet Marco 
Published: July 2019

AbstractThe experience of linguistic globalization, and the communicative disorder it entails, requires a serious retooling of most basic units of semiotic analysis. The complexity and indeterminacy of late-modern communication affects most sociolinguistic assumptions behind social interactions. In particular, we can no longer assume a model of dialogue based on shared indexical knowledge. By introducing the concept oftransidioma – i.e. the ensemble of communicative practices of people embedded in translingual environments and engaged in interactions that blend face-to-face and digitally-mediated communication – this paper documents the renewed reliance on denotational references, especially proper names, as a primary strategy to handle dialogue during asylum hearings.
Describing the Cookie Theft picture
Authors: Cummings Louise 
Published: July 2019

Abstract
Speech-language pathologists routinely use picture description
tasks to assess expository discourse in clients with disorders such as aphasia
and dementia. One picture description task – the Cookie Theft picture from the
Boston Diagnostic Aphasia Examination – has come to dominate clinical settings
more than any other task. In this article, I examine why this particular picture
description task has proven to be so successful in assessing expository
discourse in clients with language and cognitive disorders. Using data from the
University of Pittsburgh Alzheimer and Related Dementias Study, recurrent
cognitive-linguistic impairments in the Cookie Theft picture descriptions of
clients with Alzheimer’s dementia are explored. These impairments are mostly
pragmatic in nature. It is argued that the sensitivity of the Cookie Theft
picture description task to these impairments makes it an ideal assessment tool
for any investigation which aims to identify pragmatic markers of
neurodegenerative diseases such as the dementias.
The gender logic and effects of instrument mixes: implementing eldercare policy in Canada
Authors: Scala Francesca , Paterson Stephanie , Richard-Nobert Laurence 
Published: July 2019

ABSTRACTAlthough policy instruments are often conceptualized as technical or neutral tools through which ideas and outcomes are connected, this article focuses on the discursive dimensions of policy instruments in Canada’s eldercare policy to explore their gendered and gendering logics and effects. Using frame analysis, we examine government acts, public reports and policy documents to uncover how different policy instruments at the federal and subnational levels frame caregiving and the caregiver. In doing so, we identify three distinct and contradictory frames – caregiver as resource, caregiver as worker and caregiver as autonomy – and illuminate their effects for gender equality outcomes. By looking at the implementation of eldercare policies in different provinces and across different government levels, we advance a better understanding of the gendered meanings and effects of instruments mixes.

Published: July 2019

Abstract
In the present work, effective radium activity, radon exhalation rates and uranium in medicinal plants have been measured,samples collected from Iraqi markets. Sealed cup technique containing CR-39 solid state nuclear detector was used. Radium concentration varies from (0.0297 ± 0.004) Bq/kg to (0.327 ± 0.126) Bq/kg with an average of (0.142 ± 0.025) Bq/kg. The radon exhalation rate in terms of area varies from (2.287 ± 0.384) μBq/m2.d to (25.193 ± 9.729) μBq/m2.d with an average of (10.986 ± 1.989) μBq/m2.d, while uranium concentrations were ranged from (0.018 ± 0.002) ppm to (0.202 ± 0.057) ppm with an average (0.087 ± 0.002) ppm. The values of radium concentration, exhalation rates and uranium in all the medicinal plants samples were less than the recommended by the Organization of Economic Cooperation and Development (OECD), United Nations and Scientific Committee On The Effects Of Atomic Radiation (UNSCEAR) respectively. The results have revealed that the radium and uranium concentration as well as exhalation rates in studied medicinal plants and the associated exhalation radon does not pose risk to human health.
Large Geomagnetic Storms Drives by Solar Wind in Solar Cycle 24
Authors: Al-Feadh Doha , Al-Ramdhan Wathiq 
Published: July 2019

Abstract
Various solar phenomena cause anomalous circumstances in the interplanetary magnetic field (IMF) and solar wind plasma emissions. These will produce geomagnetic field disturbances for near earth space at 1AU known as geomagnetic storm.
A selection of solar magnetic storm for the period (2010-2017) have been analyzed, associated with disturbance geomagnetic storm intensity (Dst) less than (-50 nT). Through the study epoch, we found 50 great solar magnetic storms, 32 were moderate, 16 were strong, and two were severe. The major severe storm occurred on 17th of March in 2015 with (Dst ∼ - 223 nT). The most of Coronal Mass Ejection (CME) that initiated the geomagnetic storms have visual width of 360 degree, and with sky plane speed around (350-2500) Km s-1. There is a better correlation for sunspot number than (CME sky plane speed with Dst index. In this investigation, we notice that the strength of geomagnetic storms has a behavior that is in harmony with solar activity extent.
The reciprocal relation between geomagnetic activity and solar activity infers that space systems and many communications could be harmfully precious for numerous years after an exciting solar maximum.

Published: July 2019

Abstract
This work studies the gain from quantum dot plasmonic nanolaser. A metal/semiconductor/metal structure was considered to attain plasmonic nanocavity with active region contains: quantum dot, wetting layer and barrier layers. Band alignment between layers was used to predict their parameters. Momentum matrix element for transverse magnetic mode in quantum dot structure was formulated. Waveguide Fermi energy was introduced and formulated, for the first time, in this work to cover the waveguide contribution (Ag metal layer) in addition to the active region. The gain obtained here overcomes the electron scattering losses which promises in high gain, high power and high speed applications. The waveguide Fermi energy goes deep in the valence band which explains the high gain, where it is shown that covering the structure by a metal makes valence band quantum dot states fully occupied which refers to an efficient hole contribution.
