Pascale Roze à Léon Tolstoï
Authors: Schwerdtner Karin 
Published: May 2019

Dans Lettre d’été (Paris, Albin Michel, 2000), Pascale Roze s’adresse à Léon Tolstoï sur le ton d’une « vraie confidence », ce qui lui permet « d’écrire cette expérience-là » (avoir frôlé la mort) qui, sans l’écriture, serait restée secrète, cachée, inexpliquée. Par ailleurs, hantée par des questions sur la mort auxquels son destinataire ne peut répondre, l’auteure tente d’interroger à la fois l’image de lui-même et la philosophie que le grand écrivain a pu élaborer au fil de ses écrits publiés et papiers privés. Cette tentative d’interrogation l’amènera, d’une part, à établir entre eux certaines « correspondances » ou affinités et, d’autre part, à rendre sensible une différence importante d’attitude devant la vie et la mort, différence que sa très grande admiration pour le romancier russe aurait pu censurer. Selon notre hypothèse, pour l’auteure de Lettre d’été, s’adresser à Tolstoï, lui poser ses questions les plus intimes, reviendrait à incarner, par rapport à son destinataire, le semblable et le différent à la fois.
La France malade et ses récits
Authors: Gagnon Alex 
Published: May 2019

Dans l’imaginaire social français du xxie siècle naissant, l’islam devient, selon Raphaël Liogier, « la figure centrale de l’altérité indésirable ». Intrusive, sa présence est souvent considérée comme doublement menaçante, sur les plans sécuritaire et identitaire. Le phénomène n’est pas nouveau, mais il connaît, depuis le milieu des années 2000, une aggravation inédite, alors que les thèmes de l’« islamisation » de la société et de la « radicalisation » des individus alimentent de nouvelles peurs et nourrissent un récit sociétal, celui d’une invasion étrangère qui marquerait le déclin possible d’un Occident menacé. Dans la foulée, on voit apparaître, depuis quelques années, des fictions romanesques qui, s’appropriant ces thèmes, interagissent directement avec ce récit, dans une double dynamique de reprise et de rupture narratives. À partir d’une lecture du discours médiatique visant, dans un premier temps, à reconstruire ce récit sociétal de l’invasion musulmane, cet article analyse, dans un deuxième temps, cinq romans qui, parus en France entre 2012 et 2016, mettent en récit l’islamisation de la société occidentale et/ou la radicalisation ou « djihadisation » d’un personnage converti à l’islam. Il retrace ainsi divers types de transformation que la littérature contemporaine fait subir au récit sociétal : alors que certains textes s’approprient le récit d’invasion pour l’exacerber, racontant ou bien la résistance héroïque d’une Civilisation indestructible ou bien, au contraire, la déliquescence inéluctable d’une France agonisante, d’autres le mettent à distance et, en insistant sur le naufrage d’un Occident délétère, rattachent moins la barbarie à une invasion étrangère qu’à une détérioration intérieure.
Fonctionnements du festival littéraire dans les espaces culturels franco-canadiens minoritaires
Authors: Paré François 
Published: May 2019

Dans cette étude, nous nous penchons sur le phénomène des festivals littéraires (à distinguer des salons du livre) depuis le milieu des années 1990 et leur mode de fonctionnement dans le cas des communautés francophones minoritaires au Canada. Après un bref aperçu de l’histoire du festival littéraire en Amérique du Nord, l’analyse se déplace vers deux événements festivaliers qui s’imposent au Canada francophone par leur impact, leur valeur symbolique et leur longévité relative : le Festival acadien de poésie (Caraquet, Nouveau-Brunswick) et Thin Air/Livres en fête (Winnipeg, Manitoba). Nous verrons que ces deux festivals oscillent entre un souci d’autonomie institutionnelle et linguistique et, faute de public suffisant, la nécessité de négocier une place, même marginale, dans la programmation des festivals littéraires canadiens-anglais. En dernier lieu, nous proposons une réflexion théorique sur la fonction identitaire du festival littéraire dans les cultures périphériques, à savoir celle d’affirmer par la mise en scène de la voix performative de l’écrivain la vitalité de la communauté minoritaire et d’assurer la transmission intergénérationnelle du patrimoine littéraire.
Draw on me : bilinguisme minoritaire et relais littéraires franco-canadiens
Authors: Leclerc Catherine 
Published: May 2019

Après s’être atomisé à la suite de la nationalisation de la littérature québécoise, l’espace littéraire franco-canadien semble être en voie de se reconstituer, sur de nouvelles bases. Le présent article fait l’étude de ce phénomène à partir de deux traits que les littératures des minorités francophones du Canada ont en partage : le bilinguisme et la minorisation. Ces deux traits sont précisément ceux dont le Québec s’est délesté au moment où il se constituait en culture nationale. Aujourd’hui, pourtant, ils se voient octroyer une nouvelle valeur. Or, les transformations en cours dans l’espace littéraire franco-canadien et dans les idéologies linguistiques sur le contact du français avec l’anglais coïncident. Alors que le Québec s’était servi du bilinguisme minoritaire comme repoussoir, ce bilinguisme gagne à présent en statut, jusqu’à servir de modèle. S’ensuit un réaménagement des rapports hiérarchiques existant entre les divers espaces littéraires franco-canadiens, voire à l’intérieur de chacun d’eux, de même que des relais inédits des uns aux autres. Le présent article retrace ce réaménagement en se penchant sur certains textes franco-canadiens hétérolingues clés des dernières décennies, ainsi que sur leur réception.
Un théâtre en trois D dans l’Ouest canadien
Authors: Nolette Nicole 
Published: May 2019

Dans cet article, Nicole Nolette explore le potentiel du concept de « différenciation solidaire » pour l’analyse intertextuelle entre les littératures francophones de l’Ontario et de l’Ouest canadien. Les grandes figures des « trois D » de l’Ontario français (Patrice Desbiens, Robert Dickson et Jean Marc Dalpé), rejetées par la génération de Louis Patrick Leroux, réapparaissent dans la dramaturgie de Marc Prescott au Manitoba et de Gilles Poulin-Denis, originaire de la Saskatchewan. Nicole Nolette identifie les traces des trois D dans la langue, la route, la ville minière et les animaux représentés par Prescott et Poulin-Denis pour montrer comment la solidarisation littéraire de l’Ouest et de l’Ontario francophones peut également signifier une différenciation régionale.
Elevated synaptic vesicle release probability in synaptophysin/gyrin family quadruple knockouts

Published: May 2019

Synaptophysins 1 and 2 and synaptogyrins 1 and 3 constitute a major family of synaptic vesicle membrane proteins. Unlike other widely expressed synaptic vesicle proteins such as vSNAREs and synaptotagmins, the primary function has not been resolved. Here, we report robust elevation in the probability of release of readily releasable vesicles with both high and low release probabilities at a variety of synapse types from knockout mice missing all four family members. Neither the number of readily releasable vesicles, nor the timing of recruitment to the readily releasable pool was affected. The results suggest that family members serve as negative regulators of neurotransmission, acting directly at the level of exocytosis to dampen connection strength selectively when presynaptic action potentials fire at low frequency. The widespread expression suggests that chemical synapses may play a frequency filtering role in biological computation that is more elemental than presently envisioned.Editorial note: This article has been through an editorial process in which the authors decide how to respond to the issues raised during peer review. The Reviewing Editor's assessment is that all the issues have been addressed (<xref ref-type="decision-letter" rid="SA1">see decision letter</xref>).
Radiowave Propagation Ground Effects
Authors: Hill David A. 
Published: November 2024

Abstract
Radiowave propagation plays an important role in modern
communication, radar, and navigation systems. The mathematical
theory of radiowave propagation is based on
Maxwells equations [1], which were formulated by James
Clerk Maxwell in the 1860s [2]. The first free‐space radiowave
transmission experiments between a pair of antennas
were performed by Heinrich Hertz in the 1880s [3]. In
1897 Marconi first patented a wireless telegraphy system
based on long‐distance, radiowave propagation.
Sky Wave Propagation at Low Frequencies
Authors: Johler J. Ralph 
Published: November 2024

AbstractAlthough LF sky waves have been used since the earliest days of radio science, vigorous study of these waves occurred mainly between 1950 and 1970. This research was in large measure a consequence of the development of precision pulsed ground‐wave radio navigation and positioning systems. Although the ground wave is very stable with time of day, season, and so on, the ionospheric waves vary with time, and if such waves were not somehow sidestepped, the accuracy and precision of the navigation or positioning system would deteriorate. Thus, from an engineering point of view, LF sky waves were a problem in developing navigation systems such as Loran‐C or Loran‐D. One direct consequence of this research was the development of the wave hop theory of LF sky wave propagation, which will be introduced here.
Negative Resistance
Authors: King Clifford A. , Ng Kwok K. 
Published: November 2024

Abstract

It is understood that the term negative resistance refers to the dynamic characteristic, that is, the slope of the
I–V
curve (
dV/dI
) is negative.

The negative resistance devices originating from
dV/dI
being negative are discussed, followed by their applications. Finally, similar discussions on the transit‐time devices are presented.
Hankel Transforms
Authors: Rahman M. 
Published: November 2024

AbstractThe object of this article is to introduce integral transform of a particular type, called theHankel transform, and to illustrate theuseof this method by means of examples. The treatment is that of a review article and as such is not meant to be exhaustive; its aim is to give a concatenated account of known results rather than present new ones. The emphasis throughout is on those results that are of frequent occurrence in boundary value problems of mathematical physics, but some indication is also given for possible theoretical investigations.
Method of Lines
Authors: Toscano Alessandro , Vegni Lucio 
Published: November 2024

Abstract
In this contribution we present the method of lines for the analysis of the planar passive structures and planar transmission lines that are widely used in microwave and millimeter‐wave integrated circuits.
The method of partial discretization or method of lines is a well‐established technique for the analysis of different microwave structures. The method of lines is regarded as a special finite‐difference method but is more effective with respect to accuracy and computational time than is the regular finite‐difference method. It basically involves discretizing a given differential equation in one or two dimensions while using an analytical solution in the remaining direction. The method of lines has the merits of both the finite‐difference method and the analytical method; it does not yield spurious modes, nor does it have the problem of “relative convergence.”
Active Antennas
Authors: Mickelson Alan 
Published: November 2024

AbstractAn antenna is a structure that converts electromagnetic energy propagating in free space into voltage and current in an electrical circuit and vice versa. In a transceiver system, the antenna is used to both receive and transmit free‐space waves. At minimum, a transceiver then must consist of a signal source that serves to drive the antenna as well as a receiver circuit that reads out the signal from the antenna. Until relatively recently, practically all antenna systems operating in the microwave frequency regime (operation frequencies greater than 1 billion cycles per second, or 1 GHz) went to great lengths to isolate the antenna from the circuitsthat is, to find ways to make system operation independent of the antennas electrical characteristics. In contradistinction, an active antenna is one in which the antenna actually serves as a circuit element of either the driver or readout circuit.
Coplanar Waveguide (CPW) Transmission Lines
Authors: Zhu Lei 
Published: November 2024

AbstractThis article gives an overview of various coplanar waveguide (CPW) transmission lines developed to date for promising applications in monolithic microwave integrated circuits (MMICs). The article begins with a detailed description of the geometric schematics, transmission behaviors, and design formulas for the three basic CPW with infinite‐ and finite‐ground widths as well as backed conductor. Several improved CPW structures with metallic enclosure, vertical‐layer reallocation or varied conductor configurations are outlined, aiming at effectively reducing unexpected losses caused by a strip conductor, lossy substrate, or radiation in addition to problematic crosstalk effects. Coupled CPW transmission lines with different coupling architectures are briefly investigated in terms of coupling or interaction extent. Next, a variety of periodic CPW transmission lines with series inductive and/or shunt capacitive loading are presented and their slow‐wave characteristics are primarily applied for size miniaturization of CPW devices. In conclusion, guided‐wave propagation characteristics of periodic CPW are thoroughly studied in terms of dispersive and complex per unit length transmission parameters.
Frequency Converters and Mixers
Authors: Angelov Iltcho , Kollberg Erik L. , Zirath Herbert 
Published: November 2024

Abstract
An essential part of most microwave receivers is the frequency converter, a device that converts the frequency of an incoming signal to another frequency. The output frequency may be downconverted, upconverted, multiplied, or divided. Important and common is the mixer, which downconverts a high‐frequency input signal fs to a much lower and more manageable signal fIF, preserving information concerning the amplitude, frequency, and phase of the input signal. The devices used are nonlinear (i.e., the relationship between current and voltage is not linear). The devices may have either two terminals (diodes) or three terminals (transistors).
Microwave Switches
Authors: Caverly Robert H. 
Published: November 2024

AbstractModern microwave systems often require the routing of microwave signals to different locations or subsystems. This signal routing is frequently controlled electronically, and strict system requirements often require rapid signal routing. The system component used to control this flow of microwave energy is the microwave switch. Depending on the application, these devices must be able to rapidly switch applications to hundreds of kilowatts in high power radar applications. A variety of microwave switching systems are presented, including those based on ferrite technology and solid‐state and optoelectronic devices.
Rectifying Antennas (Rectennas)
Authors: Strassner Bernd H. , Chang Kai 
Published: November 2024

AbstractRectifying antennas, commonly referred to asrectennas, are integral parts of microwave power transmission or wireless power transmission (WPT ) systems. In WPT systems, RF power is transmitted from one location and captured at another location. The term rectenna consists of parts of the words “rectifier” and “antenna” since its function is to absorb incoming radiofrequency (RF ) energy and convert this energy to usable DC power. Advanced concepts for WPT , in which rectennas play a vital role, include the ground–space applications of powering aircraft and high‐altitude platforms remotely as well as space solar power where the sun's energy is transmitted from space in the form of microwaves to Earth's surface. WPT can also be useful in several ground–ground applications, including supplying power to remote locations such as islands where the infrastructure to generate power is either absent or not cost‐effective to build. However, the main future use for WPT is seen in a myriad of space–space applications. These include supplying power to space colonies and space shuttles from nuclear powered satellites. This will enable space explorers to obtain the necessary power needed, at locations far from Earth, to further explore the depths of space.
Transmitters for FM Broadcasting
Authors: Mendenhall Geoffrey N. , Fry P. E. Richard J. 
Published: November 2024

AbstractThe purpose of the FM transmitter is to convert one or more audiofrequency (composite baseband) input signal into a frequency‐modulated, radiofrequency (RF) signal at the desired power output level to feed into the radiating antenna system. In its simplest form, the FM broadcast transmitter can be considered an FM modulator and an RF power amplifier packaged in one unit.
Intermediate‐Frequency Amplifiers
Authors: Walker H. R. 
Published: November 2024

Abstract
Intermediate‐Frequency (IF) amplifiers are used to raise the signal level to a level that can be used by the decisionmaking circuits to properly utilize the received information. While raising the signal level, they must also remove adjacent channel interference and images with filters so that only the desired signal passes. There are many versions of IF amplifiers, most of which are covered here.
The most recent practice is to use integrated circuits and digital signal processing where possible. In many cases, however, this is not possible, and it is necessary to use circuits with the basic component parts in order to accomplish the desired task. The necessary design principles are given.
Double and Higher‐Order Exponentially Weighted Moving Average Control Charts
Authors: Rigdon Steven E. 
Published: November 2024

Abstract
The double exponentially weighted moving average (DEWMA) control chart has been proposed as an alternative to the usual EWMA chart. The DEWMA is a compound chart, in the sense that the output of one charting procedure (the EWMA) is used as input to another charting procedure (again, the EWMA). Triple, and even quadruple, EWMA charts have been proposed. The DEWMA can be written as a weighted average of all previous data and the initial chart statistic. These weights can have the counterintuitive property that they are not monotonically decreasing as the age of the data value increases. In addition, they require additional computations compared to the EWMA. It has been found that the optimal EWMA chart is as good, or nearly as good, as the optimal DEWMA chart. When the DEWMA chart does outperform the EWMA, in the sense of shorter average run lengths for a given process shift, the DEWMA usually performs poorly for shifts other than the one for which it was optimized.

AbstractBackgroundCOVID‐19 remains widespread and poses a threat to people's physical and mental health, especially middle‐aged and elderly individuals. Early identification of COVID‐19 patients at high risk of progressing to critical disease helps improve overall patient outcomes and healthcare efficiency.PurposeTo develop a radiomics nomogram to predict the risk of newly admitted middle‐aged and elderly COVID‐19 patients progressing to critical disease.MethodsA total of 794 patients (aged 40 years or above) were retrospectively included in the study from two institutions, all of them were with non‐critical COVID‐19 on admission. At follow‐up, patients were divided into non‐critical group and critical group. About 443 patients (384 non‐critical and 59 critical) from the first hospital were randomly assigned to the training (n = 311) and internal validation (n = 132) set in a 7:3 ratio. Additionally, an independent external cohort of 351 patients (292 non‐critical and 59 critical) from another hospital was evaluated. Radiomics signatures and clinical indicators were used to build a radiomics model and a clinical model after computed tomography (CT) image processing, CT whole‐lung segmentation, feature extraction, and feature selection. The radiomics nomogram model integrated radiomics model and clinical model. The receiver operating characteristic curve (AUC) was used to assess the performance of the proposed models. Calibration curves and decision curve analysis were used to assess the performance of the radiomics nomogram.ResultsFor the training, internal validation, and external validation sets, the AUC values of the radiomic nomogram for the prediction of COVID‐19 progression were 0.916, 0.917, and 0.890, respectively. Calibration curves indicated that there was no significant departure between prediction and observation in three sets. The decision curve image demonstrated the clinical utility of the nomogram model.ConclusionsOur nomogram model incorporates radiomics features and clinical indicators, it provides a new pathway to increase predictive accuracy or clinical utility, further helping to provide personalized management for middle‐aged and elderly patients with COVID‐19.
Tuning a secondary dose verification software for a CT‐guided online adaptive delivery system
Authors: Zhao Xiaodong , Baur Markus , Wall Phillip D. H. , Laugeman Eric 
Published: November 2024

AbstractBackgroundQuality assurance (QA) remains unstandardized for CT‐guided online adaptive radiotherapy (CTgART) platforms (Ethos, Varian Medical Systems, Inc., Palo Alto, CA), as they become more clinically prevalent. A secondary dose calculation software (Mobius3D, Varian Medical Systems, Inc., Palo Alto, CA) is provided for this closed CTgART system. However, the clinical impact of tuning dosimetric leaf gap (DLG) correction values for specific delivery techniques for CTgART secondary dose calculations remains uninvestigated.PurposeTuning the DLG correction value for different delivery techniques of the independent secondary dose verification software for adaptive online QA.MethodsA total of 31 volumetric arc therapy (VMAT) and 13 fixed‐gantry intensity modulated radiation therapy (IMRT) plans were selected from representative anatomical sites treated in our clinic. All plans were evaluated on a patient CT dataset and a QA dataset of a solid water phantom with an embedded ion chamber placed at the center in both primary treatment planning systems (TPS) and secondary dose verification software. Primary TPS plan doses were compared with secondary calculation doses on patient CT by calculating 3D gamma passing criteria under different DLG correction values ranging from –2 to 2 mm to determine the optimal DLG correction range. Ion chamber verification measurements were then compared to secondary calculation dose to determine the optimal DLG correction value by minimizing the difference for IMRT and VMAT plans, separately.ResultsThe optimal DLG correction values for VMAT and IMRT techniques were –0.3 and 0.4 mm respectively for the selected clinical cohort of patients. The mean gamma passing rate between primary and secondary doses for VMAT and IMRT were 99.0% ± 1.0% and 99.9% ± 0.1% with 3%/2 mm and excluding 10% low dose criteria. The mean ion chamber agreement for VMAT and IMRT were 0.0% ± 2.1% and 0.2% ± 1.4%.ConclusionDLG correction value should be tuned for each delivery technique (VMAT and IMRT) separately to maximize the robustness of CTgART online QA programs.
