Context.eROSITA will deliver an unprecedented volume of X-ray survey observations, 20 − 30 times more sensitive than ROSAT in the soft band (0.5 − 2.0 keV) and for the first time imaging in the hard band (2 − 10 keV). The final observed catalogue of sources will include galaxy clusters and groups along with obscured and unobscured (active galactic nuclei) AGNs. This calls for a powerful theoretical effort to mitigate potential systematics and biases that may influence the data analysis.Aims.We investigate the detection technique and selection biases in the galaxy group and AGN populations within a simulated X-ray observation conducted at the depth equivalent to a four-year eROSITA survey (eRASS:4).Methods.We generate a mock observation spanning 30 × 30 deg2based on the cosmological hydrodynamical simulation Magneticum Pathfinder fromz = 0 up to redshiftz = 0.2, mirroring the depth of eRASS:4 (with an average exposure of ∼600 s). We combined a physical background from the real eFEDS background analysis with realistic simulations of X-ray emission for the hot gas, AGNs, and XRB. Using a detection method similar to that utilised for eRASS data, we assessed completeness and contamination levels to reconstruct the luminosity functions for both extended and point sources within the catalogue.Results.We define the completeness of extended detections as a function of the input X-ray fluxS​500and halo massM500at the depth of eRASS:4. Notably, we fully recovered the brightest (most massive) galaxy clusters and AGNs. However, a significant fraction of galaxy groups (M200 < 1014 M⊙) remain undetected. Examining gas properties between the detected and undetected galaxy groups at a fixed halo mass, we observe that the detected population typically displays higher X-ray brightness compared to the undetected counterpart. Furthermore, we establish that X-ray luminosity primarily correlates with the hot gas fraction, rather than temperature or metallicity. Our simulation suggests a systematic selection bias in current surveys, leading to X-ray catalogues predominantly composed of the lowest-entropy, gas-richest, and highest surface brightness halos on galaxy group scales.

Published: June 2024

AbstractThe bacterium Vibrio vulnificus can cause severe infections internally and externally. The mortality rate of V. vulnificus-associated gangrene and septicemia has increased due to antibiotic resistance and the absence of human vaccine. Bacterial carbohydrates have been widely used in the development of bacterial vaccines. Here, a rare l-GalpNAmA-containing disaccharide that exists in V. vulnificus biotype 2 serovar A O-antigen was synthesized from d-glucose and l-galactose. An investigation on the influence of different linkers on the disaccharide synthetic efficiency indicated that the amine linker has more practicality. Two α-glycosidic linkages were constructed with good stereoselectivity by using nonparticipating C2 azido group and solvent effect. An orthogonal protection strategy allowed introductions of carboxyl and acetamidino (Am) groups at the disaccharide stage. The synthesis of the amine-linked disaccharide will provide a basis for the preparation of the trisaccharide repeating unit and longer fragments of V. vulnificus biotype 2 serovar A O-antigen, as well as other complex glycans.

Authors: Cho Yuri , Kim Bo Hyun , Lim Young-Suk 
Published: June 2024

AbstractHepatocellular carcinoma (HCC) stands as a significant contributor to mortality globally, notably in countries like Korea. In an endeavor to offer pertinent guidance for the clinical management of HCC patients, the Korean Liver Cancer Association and National Cancer Center (KLCA-NCC) Korea Practice Guideline Revision Committee recently updated the practice guidelines for HCC management. Nonetheless, disparities exist between these guidelines and the practical aspects of clinical care due to various factors. This review aims to delineate key recommendations from the 2022 iteration of the practice guidelines and present the real-world clinical landscape in Korea. Additionally, a discourse on the necessary initiatives to narrow down the divide between practice guidelines and actual clinical implementation will be provided.

Published: June 2024

ResumenLas consolidaciones viciosas de fracturas intraarticulares de falanges provocan deformidades que limitan funcionalmente y son mal toleradas. Por otra parte, su tratamiento mediante osteotomías intraarticulares está asociado a la aparición de complicaciones, principalmente la rigidez. Este artículo presenta dos casos de consolidaciones viciosas intraarticulares tratadas mediante una osteotomía extraarticular y síntesis por un método poco invasivo, el tornillo endomedular. Tras dicho procedimiento, los pacientes presentaron un rango de movimiento completo y una vuelta a sus actividades sin dolor en menos de 3 meses. Las ventajas principales de la técnica descrita son, por un lado, la evitación de las complicaciones secundarias a procedimientos intraarticulares, y, por otro, el uso de dispositivos que precisan abordajes menos agresivos y desperiostizaciones menos amplias.

Published: June 2024

ResumenLas artrodesis de muñeca, tanto totales como parciales, son opciones terapéuticas para el tratamiento de las artropatías postraumáticas, degenerativas o reumáticas. El objetivo de estas cirugías es eliminar el dolor y estabilizar la muñeca con el detrimento de pérdida de movilidad, permitiendo a los pacientes retomar sus actividades diarias sin dolor. Las artrodesis parciales tienen como objetivo conservar cierta movilidad al fusionar solo ciertas articulaciones dejando móviles solo las articulaciones no patológicas, mientras que las artrodesis totales involucran la fusión total de la muñeca, ofreciendo soluciones definitivas para el dolor intenso e inestabilidad.La realización de estas técnicas mediante cirugía artroscópica ofrece resultados similares a los de la cirugía abierta, con el beneficio adicional de minimizar las complicaciones, reducir el tiempo de recuperación y mejorar el resultado estético postoperatorio.

Published: June 2024

Infrared Reflection Absorption Spectroscopy (IRAS) on dielectric single crystals is challenging because the optimal incidence angles for light–adsorbate interaction coincide with regions of low IR reflectivity. Here, we introduce an optimized IRAS setup that maximizes the signal-to-noise ratio for non-metals. This is achieved by maximizing light throughput and by selecting optimal incidence angles that directly impact the peak heights in the spectra. The setup uses a commercial Fourier transform infrared spectrometer and is usable in ultra-high vacuum (UHV). Specifically, the optical design features sample illumination and collection mirrors with a high numerical aperture inside the UHV system and adjustable apertures to select the incidence angle range on the sample. This is important for p-polarized measurements on dielectrics because the peaks in the spectra reverse the direction at the Brewster angle (band inversion). The system components are connected precisely via a single flange, ensuring long-term stability. We studied the signal-to-noise ratio (SNR) variation in p-polarized IRAS spectra for one monolayer of CO on TiO2(110) as a function of incidence angle range, where a maximum SNR of 70 was achieved at 4 cm−1 resolution in a measurement time of 5 min. The capabilities for s polarization are demonstrated by measuring one monolayer D2O adsorbed on a TiO2(110) surface, where a SNR of 65 was achieved at a peak height ΔR/R0 of 1.4 × 10−4 in 20 min.
Multilingual mindset
Authors: Lising Loy 
Published: June 2024

Abstract
In this paper, I examine the changing currency of languages in the context of migration and mobility based on case
studies of Filipino migrants in Australia. Drawing on two sociolinguistic studies conducted with and for Filipino migrants, I
highlight how the “monolingual mindset” (Clyne, 2008) reinforced by the “White-English
complex” (Piller, Torsh, & Smith-Khan, 2023) negatively impact on the value and
currency of Philippine languages. As an alternative, I offer the concept multilingual mindset as an inclusive
framework for valuing multilingual migrants in the diaspora.
I first introduce the linguistic ecology and national language policies of both the Philippines and Australia to
set the scene for my argument. I then map out the migration trends in both countries and the simultaneous socio-political events
that have driven the growth of Filipino migration in Australia and introduce the two sociolinguistic studies with and for (Blackledge, 2006; Tetteh, 2015) Filipino
migrants. This is followed by the presentation and critical discussion of three key conceptual arguments of this paper derived
from these studies. Employing the “monolingual mindset” (Clyne, 2008) and
“White-English complex” (Piller et al., 2023) as lenses, I then critically discuss how
these concepts are detrimental to heritage language maintenance and inclusive multilingualism and argue that the
maintenance of migrant languages in the diaspora would best be facilitated by an adoption of a multilingual
mindset. The paper concludes with a discussion on the significance of the multilingual mindset to
sociolinguistic studies and migration linguistics (Borlongan, 2023), in general, and to
language attitudes, language practices, and language policies across different sectors, in particular.
Pragmatic perspectives on disagreement
Authors: Schumann Jennifer , Oswald Steve 
Published: June 2024

Abstract
The introduction to this special issue provides an overview of the notion of disagreement in relation to
argumentative practices and presents the rationale for investigating disagreement management in argumentative discourse from a
pragmatic perspective. It describes how existing accounts of disagreement in argumentation have focused on limited instances of
the phenomenon, both in terms of its pragmatic embedding (which has predominantly focused on assertive speech acts) and of its
scope (which usually covers the normative dimension of argumentative quality). The contributions to this special issue are then
presented and contextualised within this broader topic to expound how each of them addresses key pragmatic aspects of disagreement
management in argumentative discourse.
Justifying the accusation
Authors: Liberatore Diane 
Published: June 2024

Abstract
Accusations of trolling (deceiving participants about one’s
communicative intention, conducted for amusement, Dynel 2016; Hardaker 2013) and bad faith (dishonestly denying a speaker’s
committing meaning, de Saussure and Oswald
2009; Oswald 2022) abound
in digitally mediated communication. The labels chosen by
posters significantly impact the outcome of discussions, as accusations of
trolling tend to result in more abrupt settlements of disputes compared to
accusations of bad faith. However, proving these deceptive activities can be
challenging for posters. As a result, they often substantiate the “bad faith”
label by mentioning in their accusations what they perceive as strategies
indicating their interlocutors’ bad faith.
In this paper, I examine 161 accusations of trolling and bad
faith gathered from a forum. The analysis draws on Hardaker’s (2010, 2013) research and proposes a comparison of the
strategies mentioned in these accusations. The aim is to describe the ways in
which posters justify the label they opt for when confronted with deceptive
activities.
Diagnosing Thermalization Dynamics of Non-Hermitian Quantum Systems via GKSL Master Equations

Published: June 2024

Abstract
The application of the eigenstate thermalization hypothesis to non-Hermitian quantum systems has become one of the most important topics in dissipative quantum chaos, recently giving rise to intense debates. The process of thermalization is intricate, involving many time-evolution trajectories in the reduced Hilbert space of the system. By considering two different expansion forms of the density matrices adopted in the biorthogonal and right-state time evolutions, we derive two versions of the Gorini–Kossakowski–Sudarshan–Lindblad (GKSL) master equations describing the non-Hermitian systems coupled to a bosonic heat bath in thermal equilibrium. By solving the equations, we identify a sufficient condition for thermalization under both time evolutions, resulting in Boltzmann biorthogonal and right-eigenstate statistics, respectively. This finding implies that the recently proposed biorthogonal random matrix theory needs an appropriate revision. Moreover, we exemplify the precise dynamics of thermalization and thermodynamic properties with test models.
Graphene resonant pressure sensor with ultrahigh responsivity-range product
Authors: More Swapnil , Naik Akshay 
Published: June 2024

Abstract
Graphene has good mechanical properties including large Young’s modulus, making it ideal for many resonant sensing applications. Nonetheless, the development of graphene-based sensors has been limited due to difficulties in fabrication, encapsulation, and packaging. Here, we report a graphene nanoresonator-based resonant pressure sensor. The graphene nano resonator is fabricated on a thin silicon diaphragm that deforms due to pressure differential across it. The deformation-induced strain change results in a resonance frequency shift of the graphene nano resonator. The pressure sensing experiments demonstrate a record high responsivity of 20 kHz kPa−1 over a range of 270 kPa. The design has the potential to reach responsivities up to 500 kHz kPa−1. The reported responsivity is two orders of magnitude higher than the silicon-based resonant pressure sensors. The estimated resolution of pressure sensing is 90 Pa, which is 0.03% of the full-scale range of the pressure sensor. This exceptional performance is attributed to two factors: maintaining a high-quality vacuum environment for the nanoresonator and introducing stimuli through a thin silicon diaphragm. The proposed pressure sensor design provides flexibility to adjust responsivity, range and footprint as needed. The fabrication method is simple and has the potential to be integrated into the modern semiconductor foundries.

Published: June 2024

Abstract
Currently, we stand at the forefront of revolutionary advancements in communication technology. The escalating demands of advanced communication necessitate enhanced performance from materials and radio frequency devices. This paper aims to enhance film performance by depositing scandium-doped aluminum nitride (ScAlN) directly onto a Si substrate. Additionally, ScAlN was deposited on SiO2/AlN/Mo functional layers for comparison purposes. The ScAlN directly deposited on Si demonstrated superior performance in terms of crystalline quality and surface roughness, with a full width at half maximum of 1.7° and a roughness of 1.76 nm. Furthermore, a film bulk acoustic resonator (FBAR) based on the ScAlN film directly deposited on Si was successfully fabricated through thin-film transfer, with critical processes achieved via bonding and wet-etching of the substrate. The ScAlN in the fabricated resonator exhibited a favorable c-axis preferred orientation. The resulting ScAlN-based FBAR displayed a quality factor of 429. This study lays the groundwork for exciting opportunities in the development of higher-performance piezoelectric materials and devices.

Published: June 2024

Abstract
This research proposed a vibration monitoring device based on a piezoresistive flexible sensor with microstructured surfaces to achieve a simple acquisition of vibration information in the driver’s cabin of automobiles. The shape, size and arrangement mode of microstructures on the piezoresistive flexible sensor performance were investigated by finite element simulation. The polydimethylsiloxane/hydroxylated multi walled carbon nanotubes (PDMS/MWCNTs-COOH) composite membranes were prepared by the combination of high-pressure spraying and spinning coating method. The electromechanical response curves of the piezoresistive flexible sensor composed of a double-layer PDMS/MWCNTs-COOH composite membranes based on a dual-height cylindrical microstructure were tested. A vibration monitoring device was developed to process the signals obtained by the fabricated piezoresistive flexible sensor, and the vibration response of the car cab under different driving conditions was investigated. The results indicated that the cylindrical microstructure with small size can improve the sensitivity of the fabricated piezoresistive flexible sensor. Compared with the single-height and dual-height cylindrical microstructure, the piezoresistive flexible sensor with dual-height cylindrical microstructure can expand the detection range, and improve the linearity and sensitivity. The piezoresistive flexible sensor exhibits excellent performance, with a sensitivity of 1.774 kPa−1 and a detection range is 0–0.5 kPa. The above advances can improve the authenticity of the collected data, and provide a basis for the processing and analysis of the vibration signal before improving the noise, vibration and harshness performance of the vehicle.
Investigation into negative corona discharge in steam jets and distribution characteristics of charged steam jets
Authors: Zhan Wei , Yang Lanjun 
Published: June 2024

Abstract
Electricity provides a wide range of benefits for plant growth, and the electric field created by a charged steam jet exhibits significant potential for application in this field. This study investigates the electrical characteristics of charged steam jets, including the corona-discharge process, distribution of electric fields, and deposition currents. By installing a needle-ring electrode near the steam-jet exit, high-potential charged steam is generated within a confined space through the corona charging of droplets in the steam. The humid environment inside the steam jet considerably reduces the corona current compared with that of air. The outlet current is identified as a critical factor for assessing the charged steam-jet behaviour, with a higher outlet current indicating a stronger electric field and deposition current. The configuration of the electrode and the steam operational conditions, particularly the latter, affect the outlet current. Experimental results highlight the different electrical distribution characteristics of wet and saturated steam jets. Notably, the distributions of electric field and deposition currents, along with the depositional droplets and absolute-humidity increments exhibit asymmetry above and below the steam jet. This paper presents a discussion on the formation, development, and dissipative processes of charged droplets and an analysis into their possible movement trajectories under various forces. Generally, the asymmetric distribution of charged steam jets is caused by the asymmetric distribution of charged droplets or water-cluster molecules, which becomes more pronounced as one departs further from the steam-jet exit.
Dielectric anisotropy in self-assembling MXene-based lyotropic nematic compounds

Published: June 2024

Abstract
The formation of a lyotropic liquid crystal phase at the level of MXene-based aqueous dispersions due to the self-assembling capacity of these two-dimensional (2D) materials has been previously successfully reported. However, the influence of electrical external factors has been less studied in spite of the fact that understanding the electrical behaviour of 2D-based liquid crystal compounds is vital for fostering the development of new innovative applications. Consequently, within this paper, we report an in-depth evaluation of the dielectric properties of liquid crystalline phases in Ti3C2 MXene aqueous dispersions. The dependence on the low voltage of planar

orientational transition is emphasized and discussed, while the influence of the electric field frequency at the level of dielectric anisotropy is assessed in respect to various concentrations of MXene flakes within the same 2D-based compounds. Nonetheless, dielectric spectroscopy highlights the biphasic nature (containing both nematic and isotropic phases) of the studied aqueous Ti3C2 MXene inks visible up to 20% MXene. Above this concentration, the existence of a pure nematic phase in the dispersion of highMXene concentration (>20 wt%) was detected based on the evaluation of dielectric permittivity against various voltage values.
ILC sensitivity for leptophilic scalar dark matter

Published: June 2024

Abstract
We explore the viability of detecting a leptophilic scalar dark matter (DM) at the International Linear Collider (ILC) in a simplified model approach. We present the constraints on the couplings of scalar DM with the standard model fermions ensuing from the relic density bounds deduced from the 2018 Planck data. We, then, present the reach of the ILC in terms of Λ, the scale of the effective theory, by performing a detailed analysis for the Z associated DM pair production (i.e. e
