Device characteristics of the select transistor in a vertical-NAND flash memory
Authors: Kang Daewoong , Park Hyojin , Kim Dae Hwan , Cho Il Hwan 
Published: January 2023

Abstract
In this paper, variation in the parameters of the select transistor of a vertical-NAND (V-NAND) flash memory device is investigated for device optimization and performance evaluation. Device characteristics including threshold voltage (V
TH), subthreshold swing (SS) and off-current (I
OFF) are evaluated using two-dimensional device simulation. An equivalent structure of the V-NAND flash memory select transistor is suggested, which includes a fully depleted silicon-on-insulator MOSFET region and a bulk MOSFET region. The effects on device performance of parameter variation of the select transistor are investigated with physical modeling focusing on two merged MOSFET structures. Vertical channel thickness and channel scaling effects on V
TH, SS and I
OFF are studied. However, the corner shape in the select transistor has a negligible effect on device performance. The simulation results in this work can provide guidance for the design of the select transistor in V-NAND flash memory devices.
New results on the qualitative analysis of solutions of VIDEs by the Lyapunov–Razumikhin technique
Authors: Tunç Osman , Korkmaz E.

UDC 517.9
A new mathematical model described by a Volterra integro-differential equation (VIDE) with constant delay is examined. New agreeable conditions on the uniformly asymptotic stability, boundedness, and square integrability of solutions of the VIDE are obtained by using the Lyapunov–Razumikhin technique. The established conditions improve some former results and they are also nonlinear generalizations of these results. Moreover, they are weaker than some available results cited in the bibliography of this paper. Two examples are presented to demonstrate applications of these results and the introduced concepts. The use of the Lyapunov–Razumikhin technique leads to a significant difference and gives an advantage over the related methods used in the books and papers cited in the bibliography.
On a class of analytic functions closely related to a class defined by Silverman and Silvia

UDC 517.5
We define and study a class of analytic functions in the unit disc by using the modification of the well-known Silverman and Silvia's analytic formula for starlike functions with respect to a boundary point. The representation theorem, as well as growth and distortion theorems are established for the new class of functions. Further, early coefficients of the new class of functions are also estimated.
The OA
Authors: Sweeney David 
Published: January 2023

Created by the team of Brit Marling and Zal Batmanglij, and starring Marling in the role of Prairie Johnston, the Netflix Originals series The OA (2016–19) is a generically ambiguous, and ambitious, vehicle for exploring a variety of themes, chief among them identity, belief and the nature and construction of reality. Prairie claims that she has learned the secret of inter-dimensional travel after a near-death experience and subsequent imprisonment at the hands of a deranged scientist obsessed with that phenomenon – but is she a potentially unreliable narrator, a sincere one or, finally, a metafictional character playing a version of herself in a fictional drama?
This Constellation discusses The OA’s thematic concerns in the context of the creators’ earlier collaborations and in terms of influences on it, such as the work of David Lynch, particularly the TV series Twin Peaks (1990–2017) and the films Mulholland Drive (2001) and Inland Empire (2006), and comparable texts such as the Netflix Originals series Sense8 (2015–18) and the writings of Jorge Luis Borges and Philip K Dick. The discussion is supported by sources from the fields of media and social theory, including the work of Robin Nelson, Steven Shaviro, Mark Fisher and Dennis Broe. Negative criticisms of The OA are also addressed, such as accusations of superficiality, which will be considered alongside the themes of deception, manipulation and artificiality identifiable in The OA specifically, and in Marling and Batmanglij’s wider oeuvre.
The Flux Distribution and Sky Density of 25th Magnitude Main Belt Asteroids

Published: January 2023

Abstract
Digital tracking enables telescopes to detect asteroids several times fainter than conventional techniques. We describe our optimized methodology to acquire, process, and interpret digital tracking observations, and we apply it to probe the apparent magnitude distribution of main belt asteroids fainter than any previously detected from the ground. All-night integrations with the Dark Energy Camera (DECam) yield 95% completeness at R magnitude 25.0 and useful sensitivity to R = 25.6 mag when we use an analytical detection model to correct flux overestimation bias. In a single DECam field observed over two nights, we detect a total of 3234 distinct asteroids, of which 3123 are confirmed on both nights. At opposition from the Sun, we find a sky density of 697 ± 15 asteroids per square degree brighter than R = 25.0 mag, and 1031 ± 23 brighter than R = 25.6 mag. We agree with published results for the sky density and apparent magnitude distribution of asteroids brighter than R = 23 mag. For a power law defined by dN/dR ∝ 10
αR
, we find marginally acceptable fits with a constant slope α =0.28 ± 0.02 from R = 20 to 25.6 mag. Better fits are obtained for a broken power law with α = 0.218 ± 0.026 for R = 20–23.5 mag, steepening to α = 0.340 ± 0.025 for R = 23.5–25.6 mag. The constant or steepening power law indicates that asteroids fainter than R = 23.5 mag are abundant, contrary to some previous claims but consistent with theory.

Published: January 2023

Abstract
We present the on-orbit performance of the Colorado Ultraviolet Transit Experiment (CUTE). CUTE is a 6U CubeSat that launched on 2021 September 27 and is obtaining near-ultraviolet (NUV; 2480 Å-3306 Å) transit spectroscopy of short-period exoplanets. The instrument comprises a 20 cm × 8 cm rectangular Cassegrain telescope, an NUV spectrograph with a holographically ruled aberration-correcting diffraction grating, and an NUV-optimized CCD detector. The telescope feeds the spectrograph through an 18′ × 60″ slit. The detector is a passively cooled, back-illuminated NUV-enhanced CCD. The spacecraft bus is a Blue Canyon Technologies XB1, which has demonstrated ≤ 6″ jitter in 56% of CUTE science exposures. Following spacecraft commissioning, an on-orbit calibration program was executed to characterize the CUTE instrument’s on-orbit performance. The results of this calibration indicate that the effective area of CUTE is ≈19.0–27.5 cm2 and that the average intrinsic resolution element is 2.9 Å across the bandpass. This paper describes the measurement of the science instrument performance parameters as well as the thermal and pointing characteristics of the observatory.
Systematic Study of the Peak Energy of Broadband Gamma-Ray Burst Spectra

Published: January 2023

Abstract
We have performed a systematic study of gamma-ray bursts (GRBs), which have various values in the peak energy of the νF

ν
spectrum of prompt emission, E
peak, observed by the Swift/Burst Alert Telescope (BAT) and Fermi/Gamma-ray Burst Monitor, investigating their prompt and X-ray afterglow emissions. We cataloged long-lasting GRBs observed by Swift between 2004 December and 2014 February in three categories according to the classification by Sakamoto et al.: X-ray flashes (XRFs), X-ray-rich GRBs (XRRs), and classical GRBs (C-GRBs). We then derived

, as well as

if viable, of the Swift spectra of their prompt emission. We also analyzed their X-ray afterglows and found that GRB events with a lower

, i.e., softer GRBs, are fainter in 0.3–10 keV X-ray luminosity and decay more slowly than harder GRBs. The intrinsic event rates of the XRFs, XRRs, and C-GRBs were calculated using the Swift/BAT trigger algorithm. Those of the XRRs and XRFs are larger than that of the C-GRBs. If we assume that the observational diversity of E
peak is explained using the off-axis model, these results yield a jet half-opening angle of Δθ ∼ 0.°3, and a variance of the observing angles θ
obs ≲ 0.°6. This implies that this tiny variance would be responsible for the E
peak diversity observed by Swift/BAT, which is unrealistic. Therefore, we conclude that the E
peak diversity is not explained with the off-axis model, but is likely to originate from some intrinsic properties of the jets.
Reactive Rate Constants for the C+ + H2(v = 0, 1) Reaction: An Accurate State-to-state Quantum Dynamical Study
Authors: Wu Hui , Duan Zhixin , He Xiaohu 
Published: January 2023

Abstract
The accurately calculated thermal rate constants of the C+ + H2(v = 0, 1) reaction are important for estimating the CH+ emission spectra in different astronomical environments. In this study, reactive quantum dynamics of the C+ + H2(v = 0, 1) reaction have been investigated with the time-dependent wave packet method on the high-quality potential energy surface recently developed by Guo et al. The simulated total cross sections are compared in detail with previous experimental measurements and dynamical results. The calculated total rate constants are found to be in good agreement with previous quasi-classical results by Herráez-Aguilar et al., except for the v = 0 reaction at low temperatures. The ro-vibrational state-resolved rate constants show that the CH+ product, obtained from both the v = 0 and v = 1 reactions, is significantly populated in the vibrational ground but rotational excited states. In particular, for the v = 0 reaction, the CH+ product is preferably formed at j′ = 4, 5 rotational levels, while the CH+ product for the v = 1 reaction prefers rotational excitation j′ = 6–8. This finding varies with previous J-shifting calculations by Zanchet et al., owing to the different potential energy surface and methodology employed in the calculations.

Abstract
Deuterium fractionation provides a window into the thermal history of volatiles in the solar system and protoplanetary disks. While evidence of active molecular deuteration has been observed toward a handful of disks, it remains unclear whether this chemistry affects the composition of forming planetesimals due to limited observational constraints on the radial and vertical distribution of deuterated molecules. To shed light on this question, we introduce new Atacama Large Millimeter/submillimeter Array observations of DCO+ and DCN J = 2–1 at an angular resolution of 0.″5 (30 au) and combine them with archival data of higher energy transitions toward the protoplanetary disk around TW Hya. We carry out a radial excitation analysis assuming both LTE and non-LTE to localize the physical conditions traced by DCO+ and DCN emission in the disk, thus assessing deuterium fractionation efficiencies and pathways at different disk locations. We find similar disk-averaged column densities of 1.9 × 1012 and 9.8 × 1011 cm−2 for DCO+ and DCN, with typical kinetic temperatures for both molecules of 20–30 K, indicating a common origin near the comet- and planet-forming midplane. The observed DCO+/DCN abundance ratio, combined with recent modeling results, provide tentative evidence of a gas-phase C/O enhancement within <40 au. Observations of DCO+ and DCN in other disks, as well as HCN and HCO+, will be necessary to place the trends exhibited by TW Hya in context, and fully constrain the main deuteration mechanisms in disks.
Tracking the Rapid Opening and Closing of Polar Coronal Holes through IBEX ENA Observations
Authors: Shrestha Bishwas L. , Zirnstein Eric J. , McComas David J. 
Published: January 2023

Abstract
Fast solar wind (SW) flows outward from polar coronal holes (PCHs). The latitudinal extent of the fast SW varies during different phases of the solar cycle. The fast SW in the inner heliosheath produces a flatter proton spectrum than the slow SW that can be observed through energetic neutral atoms (ENAs) by the Interstellar Boundary Explorer (IBEX). In this study, we investigate the evolution of PCHs as reflected in the high-time resolution ENA flux measurements from IBEX-Hi, where the PCHs are identified by ENA spectral indices <1.8. The ENA spectral index over the poles shows a periodic evolution over the solar cycle 24. The surface area with flatter ENA spectra (<1.8) around the ecliptic south pole increases slightly from 2009–2011 and then decreased gradually from 2012–2014. The PCH completely disappears in 2016 and then starts to appear again starting in 2017, gradually growing until 2019. This evolution shows a clear correlation with the change in the PCH area observed at the Sun once the delay in the ENA observation time is included. In addition, the higher-cadence ENA data at the highest latitudes show a rapid evolution of the ENA spectrum near the south pole in 2014 and 2017. The rapid evolution in 2014 is related to a rapid closing of PCHs in 2012 and that in 2017 is related to a rapid opening of PCHs in late 2014. These results also agree qualitatively with the evolution of the ENA spectral index from simulations using a simple time-dependent heliospheric flow model.
Investigation of cultural ecosystem services supply in a river landscape: a case study in the Lower Rhine area using social media images
Authors: Tulek Betul 
Published: January 2023

River landscapes have an important function in the landscape in terms of coastal use and the opportunities they provide and they offer different cultural ecosystem services (CES). CES have a significant impact on human welfare in terms of the recreational, aesthetic and spiritual benefits these generate for people. However, the modelling and analysis of these services is more limited versus other ecosystem services due to their intangibility and subjectivity which creates unique challenges. Recently, social media data have provided an opportunity to generate spatial models of CES, offering significant cost and time advantages. Nevertheless, the usefulness of these novel data sources still requires more investigation versus more traditional survey techniques. This study aims to understand the variety of information provided by the images that users upload publicly on a daily basis to social media in a urban/rural setting. Specifically, CES provided by the open and green spaces around the Lower Rhine (Nederrijn) in Wageningen were studied using images uploaded to the social media platform Flickr. A photographic survey was then conducted to compare the utility and accuracy of these new data versus traditional techniques. In doing so, spatial data, ratings and survey evaluations related to the photographs were digitised, classified and integrated with land cover features. The results show that there is a good consistency between the two sources of data and that a wide range of CES measures can be established using these novel data sources. More work is now needed in developing spatial indicators of CES relevant to local assessments, such as the one carried out in this study.
Focusing on the Lower Rhine region as a case study, we used the Flickr digital platform to address the following three key questions:
(1) What is the spatial distribution of CES?
(2) Do users who post on the Flickr platform fully represent the cultural identity of the community and visitors in the region?
(3) Which land-cover types of the Lower Rhine region are most appreciated for CES and what are the aesthetic preferences of visitors and experts that correspond to this?
Clinical Stress and Clinical Performance in Prelicensure Nursing Students: A Systematic Review
Authors: Welch Susan R. 
Published: January 2023

Background:Stress within clinical learning environments often has been associated with nursing education. However, in the past decade, the perceived stress levels of prelicensure nursing students have not only been sustained, they have actually increased. Increased and sustained stress levels negatively affect nursing students' perceptions of their competence, confidence, and ultimately, their clinical performance.Method:A systematic review of the relationship between nursing students' perceived clinical stress and perceived clinical performance was conducted following PRISMA guidelines.Results:The review highlighted what is currently known about the relationship between perceived clinical stress in prelicensure nursing students and perceived clinical performance, providing implications for future research in clinical education. Three main themes were identified: nursing student gender, academic year, and clinical skill preparation.Conclusion:Future research with rigorous methodological designs is necessary to examine the relationship between perceived clinical stress in prelicensure nursing students and perceived clinical performance.[J Nurs Educ. 2023;62(1):36–41.]
Les livres Chourses-Coëtivy au musée Condé de Chantilly : genèse et destinée d’une collection (xve-xxie siècle)
Authors: Claerr Roseline 
Published: January 2023

La bibliothèque du musée Condé, sise en l’écrin que constitue le château de Chantilly, abrite un ensemble de livres ayant appartenu à une noble dame d’origine bretonne et de sang royal : Catherine de Coëtivy (vers 1460-1528). Cette nièce d’amiral et de cardinal bibliophiles constitua, à partir de son mariage avec Antoine de Chourses en 1478, et durant son long veuvage, une collection originale de manuscrits et d’incunables. Mis à part quelques volumes partis pour La Haye, Paris ou Stuttgart, cette collection n’a pas été disséminée : elle se trouve aujourd’hui à peu près intacte sous la garde de l’Institut de France, au musée Condé, grâce à la donation du duc d’Aumale, qui reçut cette bibliothèque en 1830 du dernier prince de Condé. Cet article s’attachera à retracer la genèse de cette collection à la fin du Moyen Âge et à l’aube de la Renaissance, pour ensuite évoquer sa réinvention par le duc d’Aumale au xixe siècle et l’exploitation scientifique qui en est faite de nos jours.
Les collectes anthropologiques de la mission Dakar-Djibouti (1931-1933) au Mali : quelle utilité scientifique ?
Authors: Dolo Akognon A. , Vialet Amélie 
Published: January 2023

La mission Dakar-Djibouti (1931-1933) est l’une des grandes expéditions de l’ethnologie française en Afrique. Organisée par l’Institut d’Ethnologie en collaboration avec le Musée d’ethnographie du Trocadéro, elle a joué un rôle important dans la rénovation de ce dernier et la création, en 1937, du Musée de l’Homme. Les collectes conséquentes (3650 pièces) ont porté sur les objets ethnographiques, mais également sur des séries anthropologiques de la région de Sangha. Ces dernières n’ont jamais été étudiées par la suite. Nous avons examiné la série conservée au Musée de l’Homme comprenant 36 crânes et 21 mandibules et nous l’avons comparée aux fossiles relevant de l’Holocène ancien de la région d’Hassi-el-Abiod et d’Asselar (Mali) et ceux des groupes préhistoriques d’Afrique du Nord : Afalou (Algérie) et Taforalt (Maroc). Les résultats montrent que les Dogons sont nettement plus petits en dimensions et d’une façon générale plus graciles, ce qui s’explique par le fait qu’ils sont aussi les plus récents des groupes considérés. Au-delà de cette étude, nous nous sommes interrogés sur les raisons du délaissement de cette série anthropologique ou de son oubli dans un contexte pourtant militant pour une approche holistique, intégrant des considérations physiques et culturelles pour caractériser les populations. C’est en effet cette démarche qui est enseignée par le tout jeune Institut d’ethnologie, créé en 1925, dont les missions qui en émanent, en territoire colonial, se devaient d’être une mise en application.
Laboratorium artificiosum
Authors: Rovelli Federica 
Published: January 2023

Les matériaux personnels employés par Beethoven au cours de son travail furent publiés pour la première fois en 1832. Se trouvait ainsi inaugurée la tradition des études musicologiques sur le processus créatif en musique. Cet article entend offrir une nouvelle occasion de réfléchir sur ce thème, qui mette l’accent sur la composition en tant que processus, matériel aussi bien que cognitif. Certaines des phases isolables dans l’activité compositionnelle de Beethoven (recueil du matériel initial ; son élaboration ; sa Textualisierung ; retouches et révisions du texte complet ; corrections de copies ou de premières éditions) sont examinées à partir d’exemples tirés de diverses typologies matérielles.
Regulation of Mesenchymal Cell Fate by Transfer of Active Gasdermin-D via Monocyte-Derived Extracellular Vesicles

Abstract
Fibrosis is characterized by inappropriately persistent myofibroblast accumulation and excessive extracellular matrix deposition with the disruption of tissue architecture and organ dysfunction. Regulated death of reparative mesenchymal cells is critical for normal wound repair, but profibrotic signaling promotes myofibroblast resistance to apoptotic stimuli. A complex interplay between immune cells and structural cells underlies lung fibrogenesis. However, there is a paucity of knowledge on how these cell populations interact to orchestrate physiologic and pathologic repair of the injured lung. In this context, gasdermin-D (GsdmD) is a cytoplasmic protein that is activated following cleavage by inflammatory caspases and induces regulated cell death by forming pores in cell membranes. This study was undertaken to evaluate the impact of human (Thp-1) monocyte-derived extracellular vesicles and GsdmD on human lung fibroblast death. Our data show that active GsdmD delivered by monocyte-derived extracellular vesicles induces caspase-independent fibroblast and myofibroblast death. This cell death was partly mediated by GsdmD-independent induction of cellular inhibitor of apoptosis 2 (cIAP-2) in the recipient fibroblast population. Our findings, to our knowledge, define a novel paradigm by which inflammatory monocytes may orchestrate the death of mesenchymal cells in physiologic wound healing, illustrating the potential to leverage this mechanism to eliminate mesenchymal cells and facilitate the resolution of fibrotic repair.
