Published: April 2023

Aims. The investigation of the feedback cycle in galaxy clusters has historically been performed for systems where feedback is ongoing (“mature-feedback” clusters), that is where the central radio galaxy has inflated radio lobes, pushing aside the intracluster medium (ICM). In this pilot study, we present results from “pre-feedback” clusters, where the central newly active radio galaxies (age < 103 yr) may not yet have had time to alter the thermodynamic state of the ICM.
Methods. We analyze Chandra and MUSE observations of two such systems, evaluating the hot gas entropy and cooling time profiles, and characterizing the morphology and kinematics of the warm gas.
Results. Based on our exploratory study of these two sources, we find that the hot gas meets the expectations for an as of yet unheated ICM. Specifically, the entropy and cooling time of pre-feedback clusters within 20 kpc from the center fall below those of mature-feedback clusters by a factor ∼2. We speculate that with an estimated mechanical power of ∼1044 − 1045 erg s−1, the two young radio galaxies may restore the entropy levels in a few tens of millions of years, which are typical values of power outbursts and lifetimes for radio galaxies in clusters. Conversely, the properties of the gas at ∼104 K seem to remain invariant between the two feedback stages, possibly suggesting that the warm gas reservoir accumulates over long periods (107 − 108 yr) during the growth of the radio galaxy. We conclude that the exploratory results obtained from our analysis of two cluster-central young radio galaxies are crucial in the context of understanding the onset of active galactic nuclei feedback, and they provide enough motivation for further investigation of similar cases.

AbstractThe phenol moiety appears in a wide variety of natural products, exhibiting biological activity, and in numerous active pharmaceutical compounds. Boronic acids are potential precursors of the phenol scaffold, and a plethora of efforts has been focused in developing novel and green protocols, targeting their chemoselective transformation into phenols. Photochemistry is a rapidly expanding research field converting light energy into chemical potential. Photochemical aerobic processes possess additional advantages to photochemistry and may find applications in chemical industries. Herein, a low-catalyst-loading anthraquinone-catalyzed photochemical process is demonstrated, under CFL lamp irradiation, while exploiting 2-Me-THF as the reaction medium for the conversion of boronic acids into phenols. Furthermore, a broad substrate scope was employed.

AbstractObjective The factors affecting the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies from mother to newborn and the duration of seropositivity rates in these infants have not yet been clearly demonstrated. The objectives of this study were to assess the levels of SARS-CoV-2 spike–specific immunoglobulin G (IgG) in women infected in the pregnancy period and newborns born to these women and to search the transplacental transfer ratio of spike-specific IgG.Methods Seventy pregnant women with symptomatic SARS-CoV-2 infection and their newborns were prospectively followed. Anti–SARS-CoV-2 immunoassay was used for the detection of the in vitro quantitative determination of total antibodies to the SARS-CoV-2 spike protein.Results Spike-specific IgG was demonstrated in 89.1% (44 of 46) of pregnant women infected more than 14 days before delivery and in 92.6% (43 of 44) of their newborns. Median transfer ratio of spike-specific Ig was 0.87 (interquartile range [IQR], 0.34–0.90), 1.0 (IQR, 0.9–0.29), and 0.81 (IQR, 0.02–1.0) in first trimester (n = 4), second trimester (n = 14), and third trimester (n = 28) pregnant women, respectively. Antibody transfer ratio was correlated with time elapsed from infection (p < 0.001). Peak antibody transfer ratio above 1 was observed at a median 60 to 120 days after the infection from delivery. Antibody transfer ratio was high in pregnant women infected more than 60 days before delivery (p < 0.001). Transfer ratio was significantly higher in the severe-critically symptomatic women (n = 15) than the mild-moderately symptomatic women (n = 55) (p = 0.001). At 3 months, 18 of 25 infants (72%) had spike-specific IgG.Conclusion Timing from infection to delivery and severity of maternal infection are critical in assessing the antibody generation and transport. Higher antibody transfer ratio can be detected in neonates when SARS-CoV-2 infection is present for more than 60 days before birth. Maternally derived antibody can persist for 3 months after birth.

AbstractInitial design cementless metal-backed patellar implants failed due to multiple reasons including implant design, use of first-generation polyethylene, and surgical technique. This study evaluates clinical outcomes and survivorship of total knee arthroplasty (TKA) using a current generation highly porous metal-backed patellar component. One-hundred twenty-five consecutive primary cementless TKAs with a compression molded highly porous metal-backed patella were reviewed. One-hundred three TKAs (82.4%) with 5-year clinical and radiographic follow-up were available for review. These were matched with 103 consecutive TKAs using a cemented patella of the same implant design. The cementless cohort had a mean age of 65.5 years, body mass index (BMI) of 33.0, and follow-up of 64.4 months. Indications for cementless TKA were based on multiple factors including age, BMI, and bone quality. There were no revisions for loosening or mechanical failure of the cementless patella compared with two cemented patellae revised for aseptic loosening. Eight patients required revisions in the cementless cohort: three for prosthetic joint infection (PJI), two for instability, one periprosthetic femur fracture, one for patella instability, and one for extensor mechanism rupture. Five patients required revisions in the cemented cohort: two for aseptic patellar loosening, one for aseptic femoral loosening, one for PJI, and one for instability. All-cause survivorship at 5 years was 92.2 and 95.1% for the cementless metal-backed implant and cemented implant cohorts, respectively. Use of a compression molded highly porous metal-backed patella component demonstrated excellent clinical and radiographic results at 5-year follow-up. Longer follow-up is required to evaluate the ability of highly porous cementless patella implants to provide durable long-term fixation.
Substrate effects on the near-field radiative heat transfer between two hBN films

Published: April 2023

Near-field radiative heat transfer (NFRHT) could surpass the blackbody limit defined by Stefan-Bolzmann’s law by several orders of magnitude, which has potential applications in thermal switching, thermal management, and photovoltaics. To further develop the NFRHT from theory to application, the substrate, which could enhance the stability of the structure, is a critical factor not to be ignored. However, the substrate effect on the NFRHT is still rarely discussed. In this work, we investigate the NFRHT between hexagonal boron nitride (hBN) films with different permittivities of the substrate. Results demonstrate that when the thickness of the film is 1 nm, increasing the permittivity of the substrate will suppress the NFRHT. In contrast, when the thickness of the film is larger (&gt;2 nm), the high-permittivity substrate could enhance the NFRHT. The spectral heat flux (SHF) corresponding to substrates with different permittivities was investigated. The SHF in Type I hyperbolic band of hBN increases with the increase in the permittivity of the substrate, while that in Type II hyperbolic band is completely opposite. This competitive relationship leads to the above-mentioned phenomenon of NFRHT. The underlying physics mechanism can also be explained by the hyperbolic phonon polaritons (HPPs), which are analyzed by the energy transmission coefficients and dispersion relations. The findings in this work will deepen the understanding of the substrate on HPPs and pave a novel way for near-field radiation devices based on hyperbolic materials.
Optimal generation of hepatic tissue-resident memory CD4 T cells requires IL-1 and IL-2

Published: April 2023

Hepatic CD4 tissue-resident memory T cells (TRM) are required for robust protection against
Salmonella
infection; however, the generation of this T cell population is poorly understood. To interrogate the contribution of inflammation, we developed a simple
Salmonella
-specific T cell transfer system that allowed direct visualization of hepatic TRM formation.
Salmonella
-specific (SM1) T cell receptor (TCR) transgenic CD4 T cells were activated in vitro and adoptively transferred into C57BL/6 mice while hepatic inflammation was induced by acetaminophen overdose or
L. monocytogenes
infection. In both model systems, hepatic CD4 TRM formation was accentuated by local tissue responses. Liver inflammation also enhanced the suboptimal protection provided by a subunit
Salmonella
vaccine which typically induces circulating memory CD4 T cells. To further elucidate the mechanism of CD4 TRM formation in response to liver inflammation, various cytokines were examined by RNAseq, bone marrow chimeras, and in vivo neutralization. Surprisingly, IL-2 and IL-1 were found to enhance CD4 TRM formation. Thus, local inflammatory mediators enhance CD4 TRM populations and can boost the protective immunity provided by a suboptimal vaccine. This knowledge will be foundational for the development of a more effective vaccine against invasive nontyphoidal salmonellosis (iNTS).
Dynamic phase evolution of MoS

Published: April 2023

Considerable efforts have been devoted to Li-S batteries, typically the soluble polysulfides shuttling effect. As a typical transition metal sulfide, MoS
2
is a magic bullet for addressing the issues of Li-S batteries, drawing increasing attention. In this study, we introduce amorphous MoS
3
as analogous sulfur cathode material and elucidate the dynamic phase evolution in the electrochemical reaction. The metallic 1T phase incorporated 2H phase MoS
2
with sulfur vacancies (SVs-1T/2H-MoS
2
) decomposed from amorphous MoS
3
achieves refined mixing with the “newborn” sulfur at the molecular level and supplies continuous conduction pathways and controllable physical confinement. Meanwhile, the in situ-generated SVs-1T/2H-MoS
2
allows lithium intercalation in advance at high discharge voltage (≥1.8 V) and enables fast electron transfer. Moreover, aiming at the unbonded sulfur, diphenyl diselenide (PDSe), as a model redox mediator is applied, which can covalently bond sulfur atoms to form conversion-type organoselenosulfides, changing the original redox pathway of “newborn” sulfur in MoS
3
, and suppressing the polysulfides shuttling effect. It also significantly lowers the activation energy and thus accelerates the sulfur reduction kinetics. Thus, the in situ-formed intercalation–conversion hybrid electrode of SVs-1T/2H-MoS
2
and organoselenosulfides realizes enhanced rate capability and superior cycling stability. This work provides a novel concept for designing high-energy–density electrode materials.
Terminological collocations in trainee and professional legal translations
Authors: Leńko-Szymańska Agnieszka , Biel Łucja 
Published: April 2023

AbstractThis paper examines how translation trainees deal with verb-noun terminological collocations when translating a legal text into their L2. The learner data is juxtaposed with professional translations of the same text and comparable non-translated documents. The results indicate that a large proportion of learner renditions is attested in the reference corpora. There is also a relatively high convergence between learners’ and experts’ choices and symmetrical variability. Unattested and inadequate equivalents demonstrate a large variability and low frequency of individual items, which suggests a lack of systematic patterns in mistranslations. The inadequacy of learner solutions is mainly caused by the choice of a collocate and results in information transfer and naturalness errors, with the former being more idiosyncratic and the latter more recurrent. In conclusion, we argue for viewing L2 collocational competence through the lens of genre requirements and professional practice rather than dichotomous categories of nativelike and non-nativelike collocations.
Exploring variation in student translation
Authors: Castagnoli Sara 
Published: April 2023

AbstractThis paper explores the issue of variation in translation, as well as its connection with the concept of “literal translation” and translator experience, on the basis of a multiple student translation corpus containing concurrent Italian versions of the same English source text produced by 35 undergraduate and postgraduate trainee translators. Translation paradigms for preselected lexical items expected to trigger different degrees of variation are extracted and analysed to identify both recurrent and sporadic solutions, whose acceptability in the target language is assessed using the source text’s official translation, alternative professional translations and theEuroparl Corpusas reference. The analysis shows that variation is most remarkable with respect to idiomatic/metaphorical and evaluative items than for non-idiomatic items, but also when a literal translation would not be possible in the target language. Translators are found to generally prefer literal translations whenever acceptable in the target language, irrespective of their degree of experience.
The (inter)subjectification ofbottom linephrases
Authors: Pinson Mathilde 
Published: April 2023

AbstractBottom lineoccurs in several phrases, including the [(the) N is] construction. Its constructionalization is more advanced than that of other nouns: it can now be used as a true discourse marker, in the left or in the right periphery. The data confirm the influence of position on pragmatic function. Cataphoricbottom linemainly fulfills discursive functions (summation, contradiction, sub-topic shift or topic-resumption), while anaphoricbottom lineis an intersubjective expression that signals turn and topic closure and aims at pre-empting potential disalignment. However, the cataphoric discourse marker is also undergoing incipient intersubjectification. This is due to the deletion of the copula, which allowsbottom lineto have scope over the interlocutor’s discourse rather than simply over its host sentence.
Making up or taunting?

Abstract
Online consumer reviews (OCRs) are characteristic of, and play a vital role in, the sharing economy, the new
business model for (in particular younger) generations of consumers. Even so, discussions of the pragmatic strategies that sharing
businesses employ in response to negative OCRs are still a scarcity in academic literature. The present article makes an original
contribution to rapport management studies by examining both the negative and positive rapport management strategies (RMS; Spencer-Oatey 2008) in the responses of British and Chinese Airbnb hosts to 200 negative
OCRs in English and 200 negative OCRs in Chinese; among the 400 responses by Airbnb hosts replying to their angry guests’ negative
OCRs, there were just 10 negative and 10 positive RMSs. The study also examines similarities and differences between English and
Chinese responses to negative OCRs.

Possible new phase transition in the 3D Ising model associated with boundary percolation
Authors: Grady Michael 
Published: April 2023

Abstract
In the ordered phase of the 3D Ising model, minority spin clusters are surrounded by a boundary of dual plaquettes. As the temperature is raised, these spin clusters become more numerous, and it is found that eventually their boundaries undergo a percolation transition when about 13% of spins are minority. Boundary percolation differs from the more commonly studied site and link percolation, although it is related to an unusual type of site percolation that includes next to nearest neighbor relationships. Because the Ising model can be reformulated in terms of the domain boundaries alone, there is reason to believe boundary percolation should be relevant here. A symmetry-breaking order parameter is found in the dual theory, the 3D gauge Ising model. It is seen to undergo a phase transition at a coupling close to that predicted by duality from the boundary percolation. This transition lies in the disordered phase of the gauge theory and has the nature of a spin-glass transition. Its critical exponent

ν
∼
1.3

is seen to match the finite-size shift exponent of the percolation transition further cementing their connection. This predicts a very weak specific heat singularity with exponent

α
∼
−
1.9

. The third energy cumulant fits well to the expected non-infinite critical behavior in a manner consistent with both the predicted exponent and critical point, indicating a true thermal phase transition. Unlike random boundary percolation, the Ising boundary percolation has two different ν exponents, one associated with largest-cluster scaling and the other with finite-size transition-point shift. This suggests there may be two different correlation lengths present.

Published: April 2023

Abstract
This is a fundamental study on a design of a plasma reactor and its electrical and hydrodynamic properties. In this study, the electrode structure suitable for this method and its installation position in the reactor were examined. The structure uses a ceramic tube and a stainless steel rod, making it possible to use high conductivity water. The pressure inside the reactor was measured, and the electrode was placed at a position where cavitation was minimum. Then, the cavitation was observed in a sample of water with a conductivity of about 10 mS m−1, and the plasma was also observed. It was found that about 20% of the total power input between the electrodes was used for plasma generation. The hydrogen peroxide concentration proportional to the input power was observed, and a concentration of about 5.5 mg l−1 was obtained at an input power of 20 W when the volume of water was 1.8 l. And also the energy yield of H2O2 generation was 5.9 g kWh−1.
Investigation of structural, mechanical, dynamic stability and electronic properties of anti-perovskite nitrides ANLa3 (A = Al, Ga): a DFT and DFPT studies
Authors: Kadri Asma , Hiadsi Said , Elchikh Mokhtar , Bahlouli Soumia 
Published: April 2023

Abstract
Various properties of anti-perovskites ANLa3 (A = Al, Ga) are investigated using the density functional theory (DFT). The GaNLa3 properties are studied for the first time. The computed lattice parameter of AlNLa3 is found to be close to other theoretical and experimental results. The mechanical stability of the present compounds are confirmed by the elastic constants estimated through the calculations. Furthermore, bulk modulus, shear modulus and Young’s modulus are evaluated. In this report, the dynamic stability and formation energy of AlNLa3 and GaNLa3 alloys are also highlighted. The state density functional perturbation theory (DFPT) is used to reveal the phonon calculation showing that the studied compounds are dynamically stable. Indeed, with a negative formation energy, it has been predicted that the GaNLa3 compound can be synthesized experimentally. Moreover, the electronic properties are studied using the Perdew–Burke–Ernzerhof Generalized Gradient Approximation (GGA-PBE) as well as a more sophisticated exchange-correlation Yukawa Screened PBE0 (YS-PBE0) hybrid functional.It has been found that the computed energy band structures within both approaches, that the anti-perovskites AlNLa3 and GaNLa3 are metallic nature. The total density of states (TDOS) and partial density of states (PDOS) are also calculated to show in evidence the contribution of atoms orbitals in the formation of bands.
Constraints on late time violations of the equivalence principle in the dark sector
Authors: Thomas Cameron C. , van de Bruck Carsten 
Published: April 2023

Abstract
If dark energy is dynamical due to the evolution of a scalar field, then in general it is expected that the scalar is coupled to matter. While couplings to the standard model particles are highly constrained by local experiments, bounds on couplings to dark matter (DM) are only obtained from cosmological observations and they are consequently weaker. It has recently been pointed out that the coupling itself can become non-zero only at the time of dark energy domination, due to the evolution of dark energy itself, leading to a violation of the equivalence principle (EP) in the dark sector at late times. In this paper we study a specific model and show that such late-time violations of the EP in the DM sector are not strongly constrained by the evolution of the cosmological background and by observables in the linear regime (e.g. from the cosmic microwave background radiation), although the model is not preferred over ΛCDM. A study of perturbations in non-linear regime is necessary to constrain late-time violations of the equivalence principle much more strongly.
