Investigation of surface topography in ultrasonic-assisted turning of C45 carbon steel
Authors: Bui Anh Tuan , Nguyen Truong Hai , Kien Le Trung , Nguyen Thanh-Hai 
Published: November 2023

Abstract
This study compares ultrasonic-assisted turning to conventional turning in terms of their effects on surface texture and cutting forces during the machining of C45 carbon steel. Experiments were conducted on a lathe equipped with a 1000 W ultrasonic generator running at 20 kHz. Ultrasonic-assisted turning results in small, evenly distributed spherical scratches on the workpiece, while conventional turning leads to long, uneven cutting marks. Significantly, ultrasonic-assisted turning achieves a notably smoother surface finish than conventional turning. As the depth of cut increases, conventional turning causes increasingly uneven surface topography, whereas ultrasonic-assisted turning maintains surface stability and uniformity. Moreover, cutting forces see a substantial rise of approximately 40% with conventional turning as the depth of cut increases. In contrast, ultrasonic-assisted turning witnesses a marginal force increase of about 15.84%.

Authors: Chai Yijun , Zhang Song , Yang Xiongwei , Li Yueming 
Published: November 2023

Abstract
The concept of patch sticking, which can be widely seen in daily life, such as medical care and houseware repair, is introduced in this work for wave manipulation. Specifically, we stick an array of patches on an aluminum plate for efficient mode conversion between in-plane longitudinal and transverse waves. The patches have a carefully designed dimension, and are stuck with specific distances and angles. The working mechanism is revealed through eigen-frequency analysis, and experimental validation is carried out. Our work offers a simple and convenient solution for elastic wave manipulation, and could inspire the design of novel meta-devices.
The Influence of Narrowing Grivet-Lenz Model on the Projector Properties of Magnetic Lenses
Authors: Mohsen Salbookh Erhaief  
Published: November 2023

present work consist of a computational investigation aims at reveal the influence of narrowing or extending Grivet-Lenz model on its own projector properties. For this reason the well known formula of Grivet-Lenz model is raised to a power named in this work by “shape factor”. Projector properties and their related variables were determined for several values of the shape factor. Results have shown that as the shape factor value increases the magnetic field become more narrowing and its projector properties efficiency get worse. Accordingly to enhance the projector properties of Grivet model it should be extended over a wide axial interval.

Published: November 2023

<p>Positron Emission Tomography (PET) imaging quality hinges on precise timing resolution, which is especially critical for Time-of-Flight (ToF) PET systems. This study assesses various data acquisition technologies to compare their timing performances for ToF-PET applications. Different read-out approaches are evaluated to extract data from Silicon Photomultipliers (SiPMs) by Fondazione Bruno Kessler (FBK) with and without metal trench (MT) technology mounted with 3×3×5 mm3 LYSO:Ce,Ca scintillator crystal pixels from SIPAT. Two onboard FPGA-based systems, the Felix Time-to-Digital Converter (TDC) from Tediel S.r.l. and the ASIC-based FastIC from the University of Barcelona, along with custom-made high-frequency electronics (CM-HF), are compared. Considering only photoelectric events, the results demonstrate substantial improvements in coincidence timing resolution (CTR) when MT SiPMs were used across various scenarios, resulting in a consistent 10 ps timing advantage compared to older SiPMs when paired with CM-HF electronics. In conjunction with other systems, timing improvement ranged from 30 to 45 ps. Notably, the Felix TDC achieved sub-100 ps timing results, emphasizing the potential of FPGA technology in ToF-PET applications. The evaluation focuses on each read-out technology’s timing resolution and explores alternative approaches for implementing novel data acquisition chains, considering system-level capabilities. The emergence of MT-type SiPMs promises superior timing performance, enhancing accuracy and efficiency in PET imaging systems. </p>

Prospects from TESS and Gaia to Constrain the Flatness of Planetary Systems
Authors: Espinoza-Retamal Juan I. , Zhu Wei , Petrovich Cristobal 
Published: November 2023

Abstract
The mutual inclination between planets orbiting the same star provides key information to understand the formation and evolution of multiplanet systems. In this work, we investigate the potential of Gaia astrometry in detecting and characterizing cold Jupiters in orbits exterior to the currently known Transiting Exoplanet Survey Satellite (TESS) planet candidates. According to our simulations, out of the ∼3350 systems expected to have cold Jupiter companions, Gaia, by its nominal 5 yr mission, should be able to detect ∼200 cold Jupiters and measure the orbital inclinations with a precision of

in ∼120 of them. These numbers are estimated under the assumption that the orbital orientations of the CJs follow an isotropic distribution, but these only vary slightly for less broad distributions. We also discuss the prospects from radial velocity follow-ups to better constrain the derived properties and provide a package to do quick forecasts using our Fisher matrix analysis. Overall, our simulations show that Gaia astrometry of cold Jupiters orbiting stars with TESS planets can distinguish dynamically cold (mean mutual inclination ≲5°) from dynamically hot systems (mean mutual inclination ≳20°), placing a new set of constraints on their formation and evolution.

Published: November 2023

Abstract
Solar eruptive activities could occur in weak magnetic field environments and over large spatial scales, which are especially relevant to eruptions involving intermediate or quiescent solar filaments. To handle the large scales, we implement and apply a flux rope embedding method using regularized Biot–Savart laws in the spherical coordinate system. Combined with a potential field source surface model and a magneto-frictional method, a nonlinear force-free field comprising a flux rope embedded in a potential field is constructed. Using the combined nonlinear force-free field as the initial condition, we then perform a zero-β data-constrained magnetohydrodynamic (MHD) simulation for an M8.7 flare at 03:38 UT on 2012 January 23. The MHD model reproduces the eruption process, flare ribbon evolution (represented by the quasi-separatrix layer evolution), and kinematics of the flux rope. This approach could potentially model global-scale eruptions from weak field regions.
Lyman Continuum Emission from Spectroscopically Confirmed Lyα Emitters at z ∼ 3.1
Authors: Liu Yuchen , Jiang Linhua , Windhorst Rogier A. , Guo Yucheng , Zheng Zhen-Ya 
Published: November 2023

Abstract
We present a study of Lyman continuum (LyC) emission in a sample of ∼150 Lyα emitters (LAEs) at z ≈ 3.1 in the Subaru-XMM Deep Survey field. These LAEs were previously selected using the narrowband technique and spectroscopically confirmed with Lyα equivalent widths (EWs) ≥ 45 Å. We obtain deep UV images using a custom intermediate-band filter U
J that covers a wavelength range of 3330 ∼ 3650 Å, corresponding to 810 ∼ 890 Å in the rest frame. We detect five individual LyC galaxy candidates in the U
J band, and their escape fractions (f
esc) of LyC photons are roughly between 40% and 80%. This supports a previous finding that a small fraction of galaxies may have very high f
esc. We find that the f
esc values of the five LyC galaxies are not apparently correlated with other galaxy properties such as Lyα luminosity and EW, UV luminosity and slope, and star formation rate (SFR). This is partly due to the fact that these galaxies only represent a small fraction (∼3%) of our LAE sample. For the remaining LAEs that are not detected in U
J, we stack their U
J-band images and constrain their average f
esc. The upper limit of the average f
esc value is about 16%, consistent with the results in the literature. Compared with the non-LyC LAEs, the LyC LAEs tend to have higher Lyα luminosities, Lyα EWs, and SFRs, but their UV continuum slopes are similar to those of other galaxies.

Abstract
Mars’s magnetosphere is hybrid, having contributions from both an induced magnetosphere like Venus and the localized crustal magnetic fields. However, the planetary fields also include large-scale, more global components. In this study, we investigate their role in Mars’s magnetospheric topological responses to the interplanetary magnetic field (IMF) clock angle using observations from the Mars Atmospheric Volatile and EvolutioN mission. We show that the large-scale planetary field has a “dipole-like” influence on the Mars global magnetosphere by examining the open field topology. We find that the “dipole-like” planetary field, as at Earth, results in a more open magnetosphere during southward IMF. The clock angle effects on the twisted magnetotail current sheet are similarly consistent with this analogy. It reinforces the idea that Mars’s magnetosphere and solar wind interaction are more Earth-like than previously thought.

Abstract
We report that minor planet 2004 CV50 displayed cometary activity in the form of a short, diffuse tail, first identified by volunteers of the Citizen Science program Active Asteroids, a NASA Partner program hosted on the Zooniverse online platform. The activity is present in three images, from UT 2020 February 15 and UT 2020 March 14, that were acquired with the Dark Energy Camera on the Blanco 4 m telescope at the Cerro-Tololo Inter-American Observatory in Chile. We find that 2004 CV50 is most likely an active quasi-Hilda object rather than an active asteroid, despite 2004 CV50 having a Tisserand parameter with respect to Jupiter of 3.06.
Nice, pépinière de revues
Authors: Arthaud Christian 
Published: November 2023

Même si la notoriété de Nice ne peut être comparée à celle de Marseille avec ses Cahiers du Sud , elle a été néanmoins un foyer dynamique pour de nombreuses revues durant tout le xx e siècle – citons Le Cahier des poètes (1912-1914), Mediterranea (1927-1939) ou Profils poétiques (1941-44 et 1951-59) –, avec un point culminant de créations entre 1970 et 1990 que nous décrivons ici. Pendant ces vingt frénétiques années des écrivains et des artistes (sans doute est-ce une particularité de Nice que de les confondre), seuls ou en groupe, vont tenter l’aventure de la revue, expérience formatrice qui perdure de nos jours dans une moindre mesure.
Quantifier le corps menstrué
Authors: Thomé Cécile 
Published: November 2023

Les applications de suivi du cycle menstruel font partie des dispositifs de quantification de soi les plus utilisés aujourd’hui en France. En s’appuyant sur une revue de la littérature internationale et sur 21 entretiens avec des jeunes femmes, cet article vise à renseigner leur genèse ainsi que leurs usages contemporains. Après un retour socio­historique permettant de situer ces applications à la fois dans la filiation des « méthodes naturelles » de contraception et de l’émergence de la « FemTech », il interroge le choix d’une application, les degrés d’intensité de son utilisation et les effets qu’elle peut avoir pour l’utilisatrice. L’article met en évidence l’importance paradoxalement secondaire de la fiabilité de l’application ainsi que de la sécurité des données. Il distingue deux types d’utilisation, restreinte et élargie, que l’âge et la position sociale contribuent à expliquer. Il renseigne l’émergence d’une « conscience menstruelle » à trois niveaux (description, interprétation, légitimation) chez les utilisatrices les plus assidues. À partir d’un objet relevant de la santé sexuelle et reproductive, il propose ainsi une contribution à la sociologie de la quantification et à celle des techniques.
Predictability of the Achieved Lenticule Thickness in Keratorefractive Lenticule Extraction for Myopia Correction
Authors: Bohač Maja , Gabrić Ivan , Gabrić Krešimir , Jagić Mateja , Arba Mosquera Samuel 
Published: November 2023

Purpose:
To assess the predictability between the SCHWIND ATOS femtosecond laser (SCHWIND eye-tech-solutions) read-out and achieved lenticule thickness measured using MS-39 anterior segment optical coherence tomography (ASOCT; CSO) at the corneal vertex at postoperative 1 day and 1 and 3 months of follow-up.

Methods:
This retrospective case series included 130 eyes of 65 consecutive patients who were treated with SmartSight (SCHWIND eye-tech-solutions) lenticule extraction. Sixty-four percent of patients were women with a mean spherical refraction of −4.98 ± 1.19 diopters (D) and mean astigmatism of 0.53 ± 0.64 D. The measurements were performed using AS-OCT with the Phoenix Software v 4.1.1.5. Lenticule thickness was obtained by the subtraction method between preoperative and postoperative total corneal thickness.

Results:
A lower reduction in central corneal thickness (CCT) compared to the laser read-out for all three follow-up visits can be observed. Essentially, the reduction in CCT was identical at 3 months versus 1 month. The reduction in CCT was lowest at postoperative 1 day. Examining the 1- and 3-month data (essentially equivalent), one can see a best fit of y = 0.94 x −7 µm.

Conclusions:
The reduction in CCT was stable from 1 month of follow-up. The stable reduction in CCT was −6% (−1.5% after accounting for design decisions) and −7 µm lower than the respective laser read-out. The findings are predictable, showing a certain level of the lenticules becoming slightly thinner than their respective laser read-outs.

Health Literacy and Health Care Utilization in Austria
Authors: Kvas Andreas , Kvas Gregor 
Published: November 2023

Background:
Efficient use of health care is crucial for health care systems; the literature reveals that health literacy (HL) plays an important role in health services utilization.

Objective:
This study aimed to analyze the relationship between HL and health care utilization in Austria.

Methods:
Registered data of 1,010 persons in the general population concerning costs of doctor visits, medication costs, and number, days, and costs of hospitalization were analyzed using a cross-sectional design for the observation period 2017 to 2019. HL was measured as general, digital, and navigational HL using the Austrian part of the European Health Literacy Survey between March 2020 and May 2020. Multivariable two-part hurdle regressions with generalized linear models, considering sociodemographic variables and chronic illnesses, were conducted to investigate the relationship between HL and health care utilization.

Key Results:
Navigational HL had a significant negative effect on the odds of causing costs at general practitioners, not adjusting (b = −0.02) and adjusting (b = −0.01) for sociodemographic variables and chronic illnesses. The effect was small, and no significant effect on any other type of analyzed health care was found.

Conclusions:

Further research on specific populations (e.g., persons with chronic diseases such as diabetes), rather than the general population, may reveal relevant effects of HL on health care utilization measured by registered data in Austria. [

Exploring the impact of graphene oxide on mechanical and durability properties of mortars incorporating demolition waste: micro and nano-pore structure effects
Authors: Chacón Bonet Cristina , Cifuentes Bulte Hector , Luna-Galiano Yolanda , Rios Jose David , Ariza Pilar , Carlos Carlos Leiva 
Published: November 2023

In this study is explored the use of construction and demolition waste as fine aggregate in mortars. The addition of nano-graphene oxide (0.1%wt) has also been evaluated. Tests were conducted to determine their density, humidity content, water absorption capacity and open void porosity (using water absorption) and the micro and nano-porosity using Hg intrusion and N2 absorption techniques, as well as their flexural and compressive strength and resistance to acid attacks. The mechanical properties of mortars manufactured with standard sand were better (30%) than made with waste aggregate. Mortars with both aggregates can be classified as M20. Nano-Graphene oxide acts as a filler, reducing the volume of macro and micro pores, thereby increasing the mechanical performance, especially when recycled aggregates are used (30% the flexural strength for recycled aggregates and 4% for standard sand). The addition of nano-graphene oxide reduces the transmission channels of acid within mortar.

Abstract
Recent evidence indicates that specific types of nuclear acids, including guanosine and its derivatives, act as natural ligands for TLR7. This led us to hypothesize that purine nucleoside phosphorylase inhibitors not only can induce apoptosis of T cells but also can lead to TLR7 activation by accumulation of guanine nucleosides, in particular under systemic inflammation, where damaged tissues release a large amount of nucleotides. We demonstrate in the present study that a purine nucleoside phosphorylase inhibitor, forodesine, can reduce the disease severity and prolong the survival in a xenogeneic mouse model of graft-versus-host disease (GVHD). Guanine nucleosides were undetectable in mice during GVHD but increased significantly following forodesine treatment. Our in vitro experiments showed that forodesine enhanced guanosine-mediated cytokine production from APCs, including alveolar macrophages and plasmacytoid dendritic cells, through TLR7 signaling. Forodesine also enhanced Ag-presenting capacity, as demonstrated by increased CD8+ T cell proliferation and higher secretion of IFN-γ and IL-12p40 in an MLR with plasmacytoid dendritic cells. Furthermore, forodesine stimulated IFN-γ production from activated T cells in the presence of a low concentration of guanosine while inhibiting their proliferation and inducing apoptotic cell death. Although forodesine ameliorated GVHD severity, mice treated with forodesine showed significantly higher levels of multiple proinflammatory cytokines and chemokines in plasma, suggesting in vivo upregulation of TLR7 signaling. Our study suggests that forodesine may activate a wide range of immune cells, including T cells, through TLR7 stimulation while inhibiting GVHD by inducing apoptosis of T cells, after allogeneic hematopoietic stem cell transplant.
