The interplay of phloem-mobile signals in plant development and stress response
Authors: Koenig Amanda M. , Hoffmann-Benning Susanne 
Published: September 2020

Abstract
Plants integrate a variety of biotic and abiotic factors for optimal growth in their given environment. While some of these responses are local, others occur distally. Hence, communication of signals perceived in one organ to a second, distal part of the plant and the coordinated developmental response require an intricate signaling system. To do so, plants developed a bipartite vascular system that mediates the uptake of water, minerals, and nutrients from the soil; transports high-energy compounds and building blocks; and traffics essential developmental and stress signals. One component of the plant vasculature is the phloem. The development of highly sensitive mass spectrometry and molecular methods in the last decades has enabled us to explore the full complexity of the phloem content. As a result, our view of the phloem has evolved from a simple transport path of photoassimilates to a major highway for pathogens, hormones and developmental signals. Understanding phloem transport is essential to comprehend the coordination of environmental inputs with plant development and, thus, ensure food security. This review discusses recent developments in its role in long-distance signaling and highlights the role of some of the signaling molecules. What emerges is an image of signaling paths that do not just involve single molecules but rather, quite frequently an interplay of several distinct molecular classes, many of which appear to be transported and acting in concert.

Abstract
Osteoprotegerin (OPG) is involved in the development of atherosclerosis and cardio-cerebrovascular disease. The goal of this meta-analysis was to evaluate the association of OPG single nucleotide polymorphisms (SNPs) with coronary artery disease (CAD) and ischemic stroke. A total of 15 eligible studies were extracted from electronic databases. Odds ratios (ORs) were presented, with 95% confidence intervals (CIs), to assess the associations. Meta-analysis was conducted using MetaGenyo, STATA, and Comprehensive Meta-Analysis. Meta-analysis of our data showed that the OPG SNP T950C was significantly associated with increased CAD risk among Asians via recessive (OR 1.55, 95% CI 1.18–2.04, P=0.002), CC vs TT (OR 1.57, 95% CI 1.16–2.11, P=0.003) and allelic (OR 1.21, 95% CI 1.05–1.38, P=0.007) models. No strong associations were observed for the OPG SNP G1181C, T245G and G209A with CAD risk. When evaluating the OPG SNP T245G and T950C associations with ischemic stroke, we found the OPG SNP T245G to be significantly associated with increased risk of ischemic stroke among Chinese via recessive (OR 1.53, 95% CI 1.02–2.29, P=0.039) and CC vs AA (OR 1.61, 95% CI 1.07–2.42, P=0.021) models. Our results suggested that the OPG SNP T950C was associated with increased risk of CAD among Asians, and the OPG SNP T245G was associated with enhanced ischemic stroke risk among Chinese.
Social Judgments of Digitally Manipulated Stuttered Speech: Cognitive Heuristics Drive Implicit and Explicit Bias
Authors: Roche Jennifer M. , Arnold Hayley S. , Ferguson Ashley M. 
Published: September 2020

Purpose
People who stutter are susceptible to discrimination, stemming from negative stereotypes and social misattributions. There has been a recent push to evaluate the underlying explicit and implicit cognitive mechanisms associated with social judgments, moving away from only evaluating explicit social bias about people who stutter. The purpose of the current study was to evaluate how listeners change their implicit and explicit social (mis)attributions after hearing a people who stutter produce disfluent speech.

Method

The current project was an adaptation of the
Byrd et al. (2017)
study to evaluate listener implicit/explicit social judgments of stuttered speech across five categories (i.e., confidence, friendliness, intelligence, distractibility, and extroversion) before and after a stuttering self-disclosure. This was done by implementing a modified version of the
Ferguson et al. (2019)
computer mouse-tracking paradigm.

Results
Consistent with previous findings, participants made more explicit positive social judgments of confidence, friendliness, extroversion, and intelligence after a stuttering self-disclosure, but the distractedness category was resistant to change. Also consistent with previous findings, participants experienced a higher degree of cognitive competition (i.e., higher area under the curve) shortly after self-disclosure, which lessened over time.

Conclusions
Explicit and implicit biases exist, but self-disclosure significantly impacts the cognitive system of listeners. Specifically, self-disclosure may reduce explicit bias through experience and explicit belief updating, but when cognitive heuristics are strong, implicit bias may be slower to change.

Published: September 2020

The state of the signal in space (SIS) broadcasted by the broadcast ephemeris will affect the reliability and safety of the user navigation and positioning. Understanding the SIS anomaly of a satellite is conducive to fault allocation in advanced receiver autonomous integrity monitoring. In this study, precise ephemeris was used to calculate the SIS error of all healthy Galileo satellites from 2017 to 2018, the detection thresholds were obtained through statistics of SIS error, and the satellite SIS anomalies for two years were detected. Results show that the SIS anomalies of Galileo satellites are primarily caused by satellite clock error, the scale of which can sometimes reach tens or even hundreds of metres. Except for E24 satellite, the annual accumulation of anomalies for Galileo satellites was <∼7 h, and the average annual accumulation of anomalies is ∼2.5 h. The accumulation of anomalies for E24 in 2017 was ∼50 h∼50 h, but this decreased to 4.5 h in 2018, indicating that its stability improved. Overall, the SIS stability in 2018 was improved compared with 2017. In addition, as the serious missing of broadcast ephemeris of Galileo satellites, it is not conducive to the continuity and reliability of the user's navigation and positioning.
Update 2020: Systemische Therapie des differenzierten und medullären Schilddrüsenkarzinoms
Authors: Kreißl Michael C. , Widmann Thomas , Genseke Philipp , Nagarajah James 
Published: September 2020

ZusammenfassungFür das fortgeschrittene Radiojod-refraktäre differenzierte Schilddrüsenkarzinom (DTC) als auch für das progrediente medulläre Schilddrüsenkarzinom sind seit mehreren Jahren Tyrosinkinase-Inhibitoren (TKI) als wirksame Therapieoptionen zugelassen. Nicht zuletzt aufgrund des Toxizitätsprofiles der TKIs erfolgt deren Einsatz individualisiert und risikoadaptiert nach Ausschöpfen lokaler palliativer Therapieverfahren und wenn bei großer Tumormasse und/oder signifikantem Fortschreiten ein weiteres Abwarten nicht mehr vertretbar erscheint. Für das DTC gibt es zwei zugelassene Tyrosinkinaseinhibitoren, Lenvatinib und Sorafenib; für das MTC sind es ebenfalls zwei, Vandetanib und Cabozantinib. Hinzu kommen, vor allem in letzter Zeit, (relativ) selektive Inhibitoren einzelner Tyrosinkinasen (z. B. BRAF, MEK, NTRK, RET und mTOR), die im Rahmen von Studien oder im individuellen Heilversuch zur Verfügung stehen. Kürzlich erlangten zwei NTRK-Inhibitoren die europäische Zulassung und können bei Vorliegen einer NTRK-Fusion eingesetzt werden; leider ist diese Fusion jedoch relativ selten beim Schilddrüsenkarzinom zu finden.In Summe sind die Nebenwirkungen der selektiven Inhibitoren meist geringer als die der bisher zugelassenen Medikamente, bei teils besserer, teils gleicher und teils etwas schlechterer Wirkung. Es steht zu erwarten, dass die selektiven Inhibitoren zukünftig das therapeutische Spektrum ergänzen werden. Grundvoraussetzung ist jedoch eine molekulare Analyse von Tumorgewebe mit Nachweis einer spezifischen Veränderung im Sinne eines „drugable target“. Um eine optimale individuelle Therapieplanung unter Berücksichtigung aller möglichen Therapieoptionen, inklusive Einschluss in klinische Studien, zu gewährleisten, sollten Patienten mit fortgeschrittenem MTC oder Radiojod-refraktären DTC interdisziplinär an spezialisierten Zentren (mit-)betreut werden.
Strahlenrisiken nach Radiojodtherapie
Authors: Kreißl Michael C. , Reinecke Maximilian , Luster Markus 
Published: September 2020

ZusammenfassungBei der Anwendung ionisierender Strahlung ist prinzipiell mit der Induktion von Zweitmalignomen zu rechnen. Dies trifft auch auf die Radiojodtherapie beim differenzierten Schilddrüsenkarzinom bzw. bei benignen Erkrankungen der Schilddrüse zu. Bei der in der Regel höher dosierten Radiojodgabe zur Behandlung des differenzierten Schilddrüsenkarzinoms ist der Effekt in einigen groß angelegten retrospektiven Studien nachweisbar und muss dem therapeutischen und auch diagnostischen Nutzen gegenübergestellt werden. Das Strahlenrisiko bei der Behandlung von gutartigen Schilddrüsenerkrankungen ist als sehr gering einzuschätzen. Eine jüngst publizierte Studie mit sehr langem Follow-up beschreibt eine dosisabhängig steigende Sterblichkeit an Zweitmalignomen im Vergleich. Eine am gleichen Kollektiv durchgeführte weitere Analyse fand jedoch nur eine erhöhte Sterblichkeit im Vergleich zur Normalbevölkerung bei Langzeitthyreostase und nicht nach Radiojodgabe.Insgesamt gilt es, im Kontext von Radiojod auch bei der Interpretation von Studiendaten, die Strahlenrisiken mit den weiteren Risiken, den Vorteilen und Vorzügen bzw. Nachteilen der alternativen Therapieoptionen in Bezug zu setzen.

ZusammenfassungDie vorliegende Arbeit gibt einen Überblick über die verschiedenen nuklearmedizinischen Verfahren in der Diagnostik bei neurodegenerativen Parkinson-Syndromen sowie ihre Evidenzlage und soll praxistaugliche Entscheidungshilfen in der Anwendung und Interpretation der Methoden und Befunde ermöglichen. Die Wertigkeit der Verfahren unterscheidet sich erheblich in Bezug auf die beiden relevanten diagnostischen Fragestellungen. Dies ist zum einen die Frage, ob überhaupt ein neurodegeneratives Parkinson-Syndrom vorliegt, zum anderen die Frage, welches. Während zur Beantwortung der ersten Frage das DAT-SPECT unter Berücksichtigung gewisser Parameter in der Praxis unbestritten die Methode der Wahl ist, eignet sich dieses Verfahren nicht zur Beantwortung der zweiten Fragestellung. Zur Unterscheidung der Parkinson-Syndrome in idiopathisch oder atypisch werden im klinischen Alltag mit der MIBG-Szintigraphie und dem FDG-PET verschiedene Verfahren angewendet. Wir legen dar, warum das FDG-PET von diesen Methoden nicht nur die geeignetste ist, um ein idiopathisches Parkinson-Syndrom von einem atypischen Parkinson-Syndrom abzugrenzen, sondern auch ausreichend valide ermöglicht, die verschiedenen atypischen neurodegenerativen Parkinson-Syndrome (d. h. MSA, PSP und CBD) voneinander zu unterscheiden, und deshalb in den Leistungskatalog der GKV aufgenommen werden sollte.

AbstractOrbital region pathologies may be safely and effectively treated through a various number of approaches. As the concept of “outcome” and minimally invasive surgery keeps gaining popularity in neurosurgery, these approaches—each with specific indications and limitations—together provide the best surgical options.
“Oh, I don’t even know how to say this in Spanish”

AbstractIn the absence of complex and diverse Latinx characters in entertainment media, film and television representations of Latinxs’ culture and language typically embody limiting and harmful stereotypes. However, the highly praised U.S.-based romantic comedy-drama “Jane the Virgin” offers a very different representation. With believable characters and complex linguistic dynamics, the show provides a positive and relatively realistic representation both of Latinxs across generations and of their linguistic repertoires as documented in community studies of Latinx language. Through an analysis of the linguistic practices of Latinx characters in “Jane the Virgin,” including patterns of intergenerational language shift, linguistic accommodation, and codeswitching, it is argued that the show acknowledges and treats as unmarked the linguistic complexity of Latinx families and communities. At the same time, the show oversimplifies this complexity in some ways, creating a representation that may be perceived as authentic despite its divergence from real-world Latinx language use.
Interpreting during the Cold War era in Turkey
Authors: Arzık-Erzurumlu Özüm 
Published: September 2020

Abstract
This article examines the way the Cold War shaped the field of interpreting in Turkey. Turkey became part of the anti-communist bloc, and one outcome of this Turkish-American partnership was the influence that a constellation of American and Turkish organizations exerted on the nascent field of interpreting. Through open-ended interviews with selected interpreters, the article seeks to shed light on the way the Cold War impacted the practice of interpreting. By drawing on Lewin’s (1947) concept of gatekeeping, it is suggested that the US-led anti-communist campaign of the Cold War affected the topics that were interpreted, the common language pairs, and interpreters’ lexical choices. The Cold War, thus, became a “gate” through which the interpreted topics, languages, lexical choices, and even the interpreters – all of which were instruments of the regime – had to pass through.
Electron-capture cross sections from atoms to hydrogen-like projectiles
Authors: Samaddar S , Jana D , Purkait K , Purkait M 
Published: September 2020

Abstract
State-selective total and projectile angular-differential cross sections for single-electron transfer to the ground state from atoms in collisions with hydrogen-like projectiles are calculated by means of the four-body distorted wave approximation in the energy range from 25 to 2500 keV amu−1. In the initial channel, the effect of the dynamic electron–electron correlation is explicitly taken into account through the complete perturbation potentials. Distortion in the initial channel due to the Coulomb continuum states of the target and the active electron in the field of the residual projectile ion is included. The quantum-mechanical prior and post transition amplitudes for single-electron capture for symmetric and asymmetric collisions are then derived in terms of three-dimensional real integrals. The role of dynamic inter-electron correlation on the cross sections as a function of the impact energy is examined. Only for He+–He collisions, the projectile angular-differential cross sections for ground state capture are calculated at different impact energies. We investigate the effect of the total cross section as well as the projectile angular-differential cross sections to the choice of different ground state wavefunction of the projectile in the final state. It is observed that although the shape of the differential cross section does not change significantly for these functions, there is a significant change of the differential cross sections due to the choice of the target description. The differential cross section reveals pronounced minima and maxima in the projectile scattering angles as the projectile energy decreases. The observed structure demonstrates the analogy of atomic de Broglie’s matter-wave scattering and Fraunhofer-type diffraction. Finally the validity of our results is assessed by comparison with available experimental data.
Tunable plasmon induced transparency and multispectral transparency with large group delay in graphene metamaterials
Authors: Fan Chunzhen , Jia Yuanlin , Ren Peiwen , Jia Wei 
Published: September 2020

Abstract
Tunable plasmon included transparency (PIT) and multispectral transparency in the THz region have been achieved with graphene metamaterials, which consist of four graphene cut wires on the dielectric substrate. The PIT transparency window originates from the bright-bright mode coupling with two sets of identical graphene stips. The electric field distribution at each resonant peak is fully examined and the number of optical resonant peaks can be flexibly altered with the designed strip length. The transmission spectra agree well with the Lorentz fitting. Moreover, multispectral transparency can also be dynamically tuned via Fermi energy (E
F). Namely, the resonant peaks move into the high frequency region with a larger E
F. The dispersion behavior is explored elaborately and the group delay can reach up to 10.22 ps, which is one magnitude higher than the previous work. Finally, the movement of the multispectral transparency with different embedded solutions is fully examined in the application of sensing. Such active and switchable graphene metamaterials may open up a new avenue in the application of optical filters, switchers or sensors.
Underwater low-velocity gas flow measurement based on passive acoustics with stable volume resolution

Published: September 2020

Abstract
Underwater gas escape is widespread in the marine and industrial fields and the low-velocity gas caused by trace gas escape is difficult to be detected or measured. An underwater low-velocity gas flow measurement method based on passive acoustics with stable volume resolution is proposed in this paper. The elastic wave signal generated by the underwater gas is acquired by a hydrophone and filtered by the wavelet packet filtering method. The flow rate can be cumulatively estimated by the relationship between the bubble and the spectrum characteristics. The volume resolution of the bubble is stable, which is achieved by adjusting the signal frequency resolution. This method is adaptive to the processing of bubbles in different volumes. The stable volume resolution is helpful to reduce the random error for the cumulative continuous bubble volume estimation. Underwater gas leakage experimental platforms were established under laboratory conditions and lake conditions. The results show that the method has high accuracy and stability. For a single bubble and low-velocity flow conditions under laboratory conditions, the minimum error is 0.3% and the maximum error is 3.9% between 5 and 25 ml min−1. For the low-velocity flow under lake conditions, the minimum error is 0.8% and the maximum error is 8% between 10 and 60 ml min−1.
Scalar spectrum in a graviton soft wall model
Authors: Rinaldi Matteo , Vento Vicente 
Published: September 2020

Abstract
In this study we present a unified phenomenological analysis of the scalar glueball and scalar meson spectra within an AdS/QCD framework in the bottom up approach. For this purpose we generalize the recently developed graviton soft-wall (GSW) model, which has shown an excellent agreement with the lattice QCD glueball spectrum, to a description of glueballs and mesons with a unique energy scale. In this scheme, dilatonic effects, are incorporated in the metric as a deformation of the AdS space. We apply the model also to the heavy meson spectra with success. We obtain quadratic mass equations for all scalar mesons while the glueballs satisfy an almost linear mass equation. Besides their spectra, we also discuss the mixing of scalar glueball and light scalar meson states within a unified framework: the GSW model. To this aim, the light-front (LF) holographic approach, which connects the mode functions of AdS/QCD to the LF wave functions, is applied. This relation provides the probabilistic interpretation required to properly investigate the mixing conditions.
Recent advances in the quantification of uncertainties in reaction theory
Authors: Lovell A E , Nunes F M , Catacora-Rios M , King G B 
Published: September 2020

Abstract
Uncertainty quantification has become increasingly more prominent in nuclear physics over the past several years. In few-body reaction theory, there are four main sources that contribute to the uncertainties in the calculated observables: the effective potentials, approximations made to the few-body problem, structure functions, and degrees of freedom left out of the model space. In this work, we illustrate some of the features that can be obtained when modern statistical tools are applied in the context of nuclear reactions. This work consists of a summary of the progress that has been made in quantifying theoretical uncertainties in this domain, focusing primarily on those uncertainties coming from the effective optical potential as well as their propagation within various reaction theories. We use, as the central example, reactions on the doubly-magic stable nucleus 40Ca, namely neutron and proton elastic scattering and single-nucleon transfer 40Ca(d,p)41Ca. First, we show different optimization schemes used to constrain the optical potential from differential cross sections and other experimental constraints; we then discuss how these uncertainties propagate to the transfer cross section, comparing two reaction theories. We finish by laying out our future plans.

Published: September 2020

Abstract
The characterization of nuisance parameters in digital silicon photomultipliers (SiPMs) is important to their understanding and future development. Methods able to distinguish the types of events are necessary to obtain fair and legitimate measurements. In this work, the zero photon probability (ZPP) method and the time delay (TD) method are used to measure the dark noise of digital SiPMs free from the contribution of correlated noise such as afterpulsing and crosstalk. It highlights the unique features of digital SiPMs such as the holdoff delay, the digital output signal, and the embedded processing (e.g. the selection of the interval sampling width). The two methods correctly separate the correlated and uncorrelated events in digital SiPMs and therefore the determination of a true photon detection efficiency (PDE) is possible. The ZPP method is also implemented inside a digital SiPM using embedded digital signal processing.
A MoSSe/blue phosphorene vdw heterostructure with energy conversion efficiency of 19.9% for photocatalytic water splitting

Published: September 2020

Abstract
We propose a novel van der Waals (vdW) heterostructure composed of MoSSe and blue phosphorene (BlueP) and investigate its structural, electronic, and optical properties by using first-principles calculations. We found that the MoSSe/BlueP vdW heterostructure exhibits robust stabilities, type-II band alignment, suitable band edge positions for water splitting, a large build-in electric field, and strong optical absorption for solar radiation, suggesing the potential of being an ideal photocatalyst for water splitting. Remarkably, it also possesses an excellent power conversion efficiency (PCE) of 12.9%. By applying biaxial tensile strains, this value can be further enhanced: the maximum PCE of 19.9% can be obtained under a 2% tensile strain. Our results are useful for designing high-efficiency photocatalysts for water splitting.
