Perspectives psychanalytiques sur l’art de l’acteur. Travail de l’acteur et construction du personnage
Authors: Ionescu Elena , Maïdi Houari 
Published: December 2023

Dans ce travail, nous nous proposons d’étudier le processus de construction du personnage par le comédien. Nous essayons d’identifier, par la mise en évidence des mécanismes psychiques impliqués dans ce processus, si cette construction n’est autre chose qu’une modalité de symbolisation d’une expérience vécue par le comédien, et qui est restée non-intégrée dans sa subjectivité. Aussi, nous cherchons à montrer la liaison entre le travail créatif du comédien et son fonctionnement psychique dans l’après-coup de ce travail.Pour développer cette étude, nous faisons appel à la littérature psychanalytique en utilisant principalement les auteurs comme Freud, Ferenczi, Winnicott, M. Klein, E. Jones, Hanna Segal, Roussillon pour leur conception sur l’art et sur la symbolisation.Lors de son travail de construction du personnage, l’artiste se met dans une condition de vulnérabilité extrême. Il met en mouvement un processus dont il n’est pas le maître absolu. Ce qui exige de lui une forme de passivation, de se laisser posséder par son propre produit artistique. La dimension masochiste de l’acteur est visée. Sa disponibilité de revivre l’angoisse face à l’inconnu, lui donne la possibilité de se rapprocher de cette expérience, à peine aperçue, de raconter quelque chose sur elle, à lui donner une place, à l’inscrire dans le temps. Le choix du medium, les moyens techniques que l’artiste va utiliser dans le processus créatif, sont spécifiques à chaque type d’art et mobiliseront des contenus inconscients différents et des modalités particulières pour les traiter. En parlant de l’acteur, nous devons prendre en considération le fait que son instrument principal de représentation, la matière première de son produit artistique, est son propre corps. Ainsi, sont enclenchés des processus inconscients particuliers, comme la sublimation ou la symbolisation, que nous avons cherché à explorer.
Earnings management of acquiring and non-acquiring companies: the key role of ownership structure and national corporate governance in GCC
Authors: Alghemary Mahmoud , Polovina Nereida , Al-Najjar Basil 
Published: December 2023

AbstractWe are mainly interested in the impact of acquisition, ownership structure, and national governance quality on accrual earnings management (AEM) in the GCC listed companies’ context. Our sample is composed of 3210 firm-year observations for the period from 2007 to 2017. We employ panel data models in investigating the determinants of AEM for acquiring and non-acquiring firms. The findings reveal that acquiring firms involve more in earnings management than non-acquiring firms and that acquiring firms involve in AEM through income increasing rather than income decreasing. Institutional and state ownership are found to be an efficient tool in restraining companies’ engagement in earnings management whereas foreign ownership is shown to have no impact. National governance quality is found to be an efficient mechanism to reduce the companies’ engagement in earnings management. The study has both organizational and policy implications. In the organizational context, the GCC listed companies could benefit from attracting institutional and state owners to mitigate earnings management and therefore enhance firm performance. In the legislative context, policy makers are encouraged to concentrate on developing national governance systems to mitigate AEM.
Considering a superposition of classical reference frames
Authors: Tammaro Elliott , Angle H. , Mbadu E. 
Published: December 2023

A ubiquitous feature of quantum mechanical theories is the existence of states of superposition. This is expected to be no different for a quantum gravity theory. Guided by this consideration and others we consider a framework in which classical reference frames may be in superposition relative to one another. Mirroring standard quantum mechanics we introduce a complex-valued wavefunctional, which takes as input the transformations between the coordinates, Ψ[x(x′)], with the interpretation that an interaction between the reference frames may select a particular transformation with probability distribution given by the Born rule — P[x(x′)] = probability distribution functional ≡ |Ψ[x(x′)]|2. The cases of two and three reference frames in superposition are considered explicitly. It is shown that the set of transformations is closed. A rule for transforming wavefunctions from one system to another system in superposition is proposed and consistency with the Schrodinger equation is demonstrated.
Design, optimization, and characterization of an XY nanopositioning stage with multi-level spatial flexure hinges for high-precision large-stroke motion guidance
Authors: Shi Zhichao , Li Xiaoquan , Zhu Zhiwei 
Published: December 2023

Establishing a novel design and accurate analytical models for XY nanopositioning stages based on voice coil motor (VCM) actuators is critical to achieving an optimal working performance. To overcome the existing design challenges of 2-degree-of-freedom guiding mechanisms, a four-layer structure composed of L-shaped spatial double parallelogram flexure mechanisms was proposed for the magnetic stage, which exhibits light weight and inhibits parasitic and decoupled motions. The guiding mechanisms were modeled by the compliance matrix method. Thereafter, by combining an electromagnetic model for the VCMs with the equivalent magnetic network method, an electromagnetic–mechanical coupling optimization method with multiple constraints was proposed for the stage to achieve a millimeter-range motion with a maximized natural frequency. The mechanical and electromagnetic performances were then verified by finite element analysis software. The optimized prototype was tested with a stroke of ±3.41 and ±3.08 mm for X axis and Y axis, respectively, a closed-loop resolution of 100 nm for X axis and 150 nm for Y axis, and a resonant frequency of 11.75 Hz for both axes. The tracking of a 0.1 Hz spiral of Archimedes achieved a maximum tracking error of 2.9%.
Tightly coupled arrays with time-domain beam scan for the radiation of high-power ultrawideband electromagnetic pulses

Published: December 2023

In this paper, a kind of tightly coupled array (TCA) with time-domain beam scan is developed for the radiation of high-power ultrawideband (UWB) electromagnetic pulses, and the peak-power pattern is proposed to characterize the directivity. First, the active voltage standing wave ratio (AVSWR) bandwidth of the TCA is optimized, which is the precondition for the beam scan. It indicates that the lower-cutoff frequency (LCF) is inversely proportional to the total length of the whole array; an increase in the distance between the array and the ground plane could remarkably reduce the LCF; and an increase in the element number can also decrease the LCF because of the increase in length, but more elements would make the center elements difficult to match in the low-frequency range, so there is a limitation on the number of elements for a certain LCF. Based on these results, a six-element linear array is designed. Then, the definition of the peak-power pattern is proposed to characterize the directivity of the UWB pulsed antenna. Finally, the optimized six-element array is developed, and the measured working band is 276 MHz–6.4 GHz (AVSWR &lt; 3). The effective potential gain is 1.76, and it improves by 51.7% with a reduction in the aperture area by 68.4% compared with the previous TCA, which means that the aperture efficiency is remarkably improved. The half-power beam width of the developed TCA with the scan angle of 0° is 45°. The time-domain beam scan could be performed with time-delay feeding lines, and the maximum scan angle is over ±30° in the E-plane. The developed TCA can be applied for the generation of high-power electromagnetic environments for the study of intentional electromagnetic interference.

Published: December 2023

We present the development of a flexible tape-drive target system to generate and control secondary high-intensity laser-plasma sources. Its adjustable design permits the generation of relativistic MeV particles and x rays at high-intensity (i.e., ≥1 × 1018 W cm−2) laser facilities, at high repetition rates (&gt;1 Hz). The compact and robust structure shows good mechanical stability and a high target placement accuracy (&lt;4 μm RMS). Its compact and flexible design allows for mounting in both the horizontal and vertical planes, which makes it practical for use in cluttered laser-plasma experimental setups. The design permits ∼170° of access on the laser-driver side and 120° of diagnostic access at the rear. A range of adapted apertures have been designed and tested to be easily implemented to the targetry system. The design and performance testing of the tape-drive system in the context of two experiments performed at the COMET laser facility at the Lawrence Livermore National Laboratory and at the Advanced Lasers and Extreme Photonics (ALEPH) facility at Colorado State University are discussed. Experimental data showing that the designed prototype is also able to both generate and focus high-intensity laser-driven protons at high repetition rates are also presented.
Impact of errors in the magnetic field measurement on the precision determination of neutrino oscillation parameters at the proposed ICAL detector at INO
Authors: Khindri Honey , Indumathi D. , Mohan Lakshmi S. 
Published: December 2023

Abstract
The magnetised iron calorimeter (ICAL) detector proposed at
the India-based Neutrino Observatory will be a 51 kton detector made
of 151 layers of 56 mm thick soft iron with 40 mm air gap in
between where the RPCs, the active detectors, will be placed. The
main goal of ICAL is to make precision measurements of the neutrino
oscillation parameters, especially of the neutrino mass ordering,
using the atmospheric neutrinos as source. The charged current
interactions of the atmospheric muon neutrinos and anti-neutrinos in
the detector produce charged muons. The magnetic field, with a
maximum value of ∼ 1.5 T in the central region of ICAL, is a
critical component since it will be used to distinguish the charges
and determine the momentum and direction of these muons. It is
difficult to measure the magnetic field inside the iron. The
existing methods can only estimate the internal field and hence will
be prone to error. This paper presents the first simulations study
of the effect of errors in the measurement of the magnetic field in
ICAL on its physics potential, especially the neutrino mass ordering
and precision measurement of oscillation parameters in the 2–3
sector. The study is a GEANT4-based analysis, using measurements of
the magnetic field at the prototype ICAL detector. We find that
there is only a small effect on the determination of the mass
ordering. While local fluctuations in the magnetic field measurement
are well-tolerated, calibration errors must remain well within 5%
to retain good precision determination of the parameters

Shutdown of Atlantic overturning circulation could cause persistent increase of primary production in the Pacific
Authors: Liebermann Ralf , Hofmann Matthias , Feulner Georg 
Published: December 2023

Abstract
A potential shutdown of the Atlantic meridional overturning circulation (AMOC) is commonly recognized to have a significant impact on the Northern hemispheric climate, notably in Northern Europe. The collapse of the northbound heat transport by the AMOC is supposed to cool down surface air temperatures at the Scandinavian coast by up to 6 K accompanied by a concomitant nutrient starvation of phytoplankton in Subarctic and Arctic regions. However, besides local and regional impacts, tipping the AMOC into a weaker state by anthropogenic carbon dioxide (CO2) and associated freshwater forcing could also have surprising remote effects. In order to investigate possible long-term impacts of an AMOC shutdown on ocean biogeochemistry, we employ an Earth system model of intermediate complexity using idealized scenarios of century-scale atmospheric 2×CO2 and 4×CO2 pulses combined with North Atlantic freshwater forcing. The results show a continued increase in primary production, in particular in the Eastern equatorial Pacific, due to a decrease in iron limitation following the AMOC shutdown. Tracer simulations indicate that bioavailable dissolved iron brought by Aeolian dust into the subtropical gyres of the Atlantic Ocean is transported to the Southern Ocean and from there enters the Indian Ocean and the Pacific. Thereby, the additionally introduced iron fertilizes the phosphate-rich high-nutrient, low chlorophyll waters, giving a lasting boost to phytoplankton growth, especially in the Eastern equatorial Pacific.
Synergistic impacts of wintertime regional snow anomalies in the Northern Hemisphere on the summer rainfall pattern in China

Published: December 2023

Abstract
Changes in winter snow cover in the Northern Hemisphere (NH) could have a profound impact on mid-latitude weather. Previous studies have focused on the role of regional, e.g. Eurasian or Tibetan, snow cover in summer precipitation anomaly, without considering the synergistic impacts of hemispheric wintertime snow. In this study, we find that the dominant pattern of the NH winter overall snow cover anomaly with a synergistic impact, has a stronger cross-seasonal association with the China’s summer rainfall pattern than regional snow cover anomaly. We summarize three synergistic impact paths of regional snow cover. One is extratropical path, that is the westerlies are affected by less snow in Europe through the snow-soil moisture-atmospheric feedback, and the influence is strengthened by less snow in Mongolia through enhanced temperature anomalies. The second is subtropical path, that is the meridional thermal difference anomaly caused by more snow anomaly on the Tibetan Plateau is strengthened by less Mongolian snow and then impacts the behavior of the upper-tropospheric westerly jet. Third, concurrently, more North American snow enhances the above two synergistic influence paths via the Circumglobal Teleconnection pattern. These three paths can be simultaneously reflected in the associated circulations of the first mode of NH snow cover. Their synergistic impacts eventually influence the meridional East Asia-Pacific pattern circulation anomalies in summer, leading to increased precipitation in the Yangtze River Basin. The cross-seasonal influences of synergistic effects of multiple regional snow anomalies can be identified by CMIP6 multi-model ensembles, particularly the impact of European snow cover.

Published: December 2023

Abstract
This study conducted at the Dujail, north of Baghdad, aims to control the downy mildew disease of cucumber based on the ventilation of greenhouses by making three ventilation holes in the plastic cover, in comparison to cultivation into a regular greenhouse (without ventilation holes). Three approved cucumber hybrid were included in this study; Mustaqbal, Jamilah, and Faris. The infection percentage and disease severity rates were calculated since the onset of the disease on March 21st, 2022 until May 18th, 2022. The results showed that the average temperatures (minimum and maximum) and relative humidity were 5-25 ºC and 97% inside the regular greenhouse were suitable for the Pseudoperonospora cubensis natural infection. The highest percentage of infection and disease severity were 30.81 and 23.33%, respectively, reported into the regular greenhouse (without ventilation), compared with the infection percentage and disease severity in the ventilated greenhouses, which were 1.28 and 6.99%, respectively. The percentages of infection of Mustaqbal, Faris and Jamila in the regular greenhouse (without ventilation) were 31.69, 31.40 and 29.35%, respectively, compared to 1.47, 1.17 and 1.21% noticed in the greenhouses with three ventilation holes for the same cucumber varieties, respectively. This study found that three ventilation holes in plastic cover of the greenhouse reduced the percentage infection and disease severity in cucumber plants, by 95.8 and 70% respectively.
