Abstract
Cutting temperature is playing a key role in evaluating the cutting process, which significantly affects the tool wear and the quality of the workpiece. Aiming at the problems of low precision, low aging, and poor stability of cutting temperature measurement on the front tool face, an integrated design and production scheme of a high sensitivity built-in wireless temperature measurement tool was proposed. The temperature distribution position on the front tool face was analyzed with 3D finite element simulation software, and the thermal contact position of the main and secondary film thermocouples was determined. SiO2 insulated films and NiCr/NiSi film thermocouples were prepared on the front tool surface by femtosecond laser micromachining, electrolyte-plasma polishing, plasma enhanced chemical vapor deposition and magnetron sputtering, and a static calibration experiment system for sensitivity and accuracy of the temperature measuring tool for the film thermocouple was established, and Seebeck coefficient of the film thermocouple was obtained. According to the actual cutting conditions, the wireless temperature measuring system of the thin film thermocouple tool was built and the field cutting test was carried out to obtain the influence law of different cutting parameters on the cutting temperature, and further verify the feasibility of the thin film temperature measuring sensor. The research results show that: Seebeck coefficients of the two kinds of thermocouples prepared by the NiCr/NiSi thin film thermocouple temperature measuring tool are 34.97 μV/°C and 34.96 μV/°C, and the slope of the temperature data fitting curve is 1.00398 and 0.997475, respectively. The linear correlation coefficient R2 is close to 1, which is close to the standard K-type thermocouple, which shows good sensitivity and accuracy. At the same time, the temperature measurement results are close to the commercial standard K thermocouple, and the error is less than 5%, indicating that the developed film thermocouple has a high measurement accuracy and can meet the needs of temperature measurement. Actual cutting test is carried out with developed wireless temperature measuring device of thin film thermocouple, which shows this device can meet the requirements of tool temperature measurement, and the feasibility of thin film temperature measuring sensor is further verified. The research provide technical reference for industrial intelligent manufacturing in order to realize the wireless measurement of cutting area temperature of tool front.
Lexicon and Logic: A Corpus-Based Investigation Into a Connection Between Prepositional Senses and Quantifier Scope

Abstract
Previous research has indicated that abstract grammatical rules and forms fall short of predicting quantifier scope and that lexical/pragmatic knowledge plays a significant part in quantifier scope disambiguation (QSD). More recent works have argued that world knowledge in the form of relations among objects may be salient to QSD. This paper contributes to this line of research by providing support to the claim that there is a connection between our lexical knowledge about preposition meanings and quantifier scope. More specifically, we propose that certain prepositional senses encode dependency relations that have an effect on scope-taking preferences. For example, the preposition of expressing ‘part-whole sense’ contributes to our choice of the inverse scope reading for the construction a day of every month by introducing a dependency between wholes (months) and their respective parts (days). Quantifying over this dependency yields the inverse scope reading: for every month, there is a different day that belongs to it (every month &gt; a day). Furthermore, universal quantification in locative and temporal prepositional phrases tends to support inverse scope. For example, the locative preposition on — as in a store on each side of the street — implies ‘disjointness’ (objects do not occupy more than one place at a time), and hence can be interpreted as a dependency between each side of the street and the respective stores located on them. Quantifying over this dependency yields the inverse scope reading: for each side of the street, there is a different store located on it (each side of the street &gt; a store). For studying the connection between prepositional senses and quantifier scope in the wild, we use a scope-disambiguated corpus created by AnderBois et al. ( 2012), additionally annotated with prepositional senses using the Semantic Network of Adposition and Case Supersenses (SNACS) scheme proposed in Schneider et al. ( 2018, 2020). The results of the corpus study combined with psycholinguistic experiments support the claim made here that certain prepositional senses are strong predictors of quantifier scope.
Full-model estimation for non-parametric multivariate finite mixture models
Authors: Du Roy de Chaumaray Marie , Marbac Matthieu 
Published: January 2024

Abstract
This paper addresses the problem of full-model estimation for non-parametric finite mixture models. It presents an approach for selecting the number of components and the subset of discriminative variables (i.e. the subset of variables having different distributions among the mixture components) by considering an upper bound on the number of components (this number being allowed to increase with the sample size). The proposed approach considers a discretization of each variable into B bins and a penalization of the resulting log-likelihood. Considering that the number of bins tends to infinity as the sample size tends to infinity, we prove that our estimator of the model (number of components and subset of relevant variables for clustering) is consistent under a suitable choice of the penalty term. The relevance of our proposal is illustrated on simulated and benchmark data.
Striking energy deals in disputed seas: the case of the Gaza Marine gas field
Authors: Rettig Elai , Spanier Benny 
Published: January 2024

Abstract
In June 2023, Israel approved the development of Gaza Marine, a small offshore gas field near the Gaza Strip that has remained dormant since its discovery in 2000. The field can potentially benefit the Palestinian Authority (PA) in terms of export revenue and energy independence. However, the legal status of the field remains unclear, and the 2023 Israel–Hamas war further complicated this matter. On the one hand, although Israel has not made any legal claim to Gaza Marine, its approval to develop the field is still considered necessary by all parties involved. On the other hand, while the PA views itself as the rightful owner of the field, it has had no effective control over Gaza’s coastline or waters since 2007, weakening its claim. This article reviews the complex history and evolving legal status of the Gaza Marine gas field up until the 2023 war. It argues that there is still room for optimism regarding the future development of the field, especially when considering its similarities to the successful 2022 maritime agreement between Israel and Lebanon.

Published: January 2024

Abstract

Objective
To study the frequency of microbiological etiology of respiratory infections in patients with long COVID and their associated clinical and radiological findings.

Methods
Nasopharyngeal swabs and sputum specimens were collected from 97 patients with respiratory illness stemming from long COVID. The specimens were assessed for their microbiological profile (bacteria and virus) and their association with the overall clinical and radiological picture.

Results
In total, 23 (24%) patients with long COVID had viral infection (n = 12), bacterial infection (n = 9), or coinfection (n = 2). Microorganisms were detected at significantly higher rates in hospitalized patients, patients with moderate COVID-19, and patients with asthma (P &lt; .05). Tachycardia (65%) was the most common symptom at presentation. A statistically significant number of patients with long COVID who had viral infection presented with cough and myalgia; and a statistically significant number of patients with long COVID who had bacterial infection presented with productive coughing (P &lt; .05). Post-COVID fibrotic changes were found in 61% of cohort patients (31/51).

Conclusion
A decreasing trend of respiratory pathogens (enveloped viruses and bacteria) was found in long COVID. An analysis including a larger group of viral- or bacterial-infected patients with long COVID is needed to obtain high-level evidence on the presenting symptoms (cough, myalgia) and their association with the underlying comorbidities and severity.
Disguised Among the Sea: The Implications of Artificial Islands on Casualty Care in the Indo-Pacific

Published: January 2024

ABSTRACT
As reported in the 2022 Biden-Harris National Security Strategy, China is perceived as the primary U.S. competitor with the intent and means to become the world’s greatest superpower. China’s efforts, which are at odds with America’s ambition to maintain its global influence, are complemented by ostensibly harmless “gray zone tactics,” defined as coercive geopolitical, economic, military, and cyber activities below the use of kinetic military force. Such tactics may be utilized with seemingly innocuous intentions, but in reality, they can complicate U.S. combat casualty care in the event of an Indo-Pacific conflict. One tactic of particular impact is China’s development of artificial islands throughout the South China Sea. By creating these islands, China is expanding its reach beyond its continental borders. These islands, alongside China’s well-developed naval and missile capabilities, will cause disruptions to U.S. casualty care staging, medical resupply, and aeromedical evacuations. To mitigate those threats, the USA should implement a robust regional Combatant Command Trauma System, improve global health security cooperation with local partner nations, and implement irregular or guerilla trauma systems that meet medical needs in impromptu, clandestine settings. Operational recommendations based on these efforts could include pre-positioning tactical combat casualty care and damage control resuscitation supplies and developing with nearby host-nation evacuation platforms such as small boat operators. These solutions, among others, require years of training, relationship-building, and capability development to institute successfully. As a result, U.S. Military leaders should act now to incorporate these strategies into their irregular warfare, low-intensity conflict, and large-scale combat operation toolkits.
The role of environment and AGN feedback in quenching local galaxies: comparing cosmological hydrodynamical simulations to the SDSS
Authors: Goubert Paul H , Bluck Asa F L , Piotrowska Joanna M , Maiolino Roberto 
Published: January 2024

ABSTRACT
We present an analysis of the quenching of local observed and simulated galaxies, including an investigation of the dependence of quiescence on both intrinsic and environmental parameters. We apply an advanced machine learning technique utilizing random forest classification to predict when galaxies are star forming or quenched. We perform separate classification analyses for three groups of galaxies: (a) central galaxies, (b) high-mass satellites ($M_{*} \gt 10^{10.5}\,{\rm {\rm M}_{\odot }}$), and (c) low-mass satellites ($M_{*} \lt 10^{10}\,{\rm {\rm M}_{\odot }}$) for three cosmological hydrodynamical simulations (Evolution and Assembly of GaLaxies and their Environments, Illustris, and IllustrisTNG), and observational data from the Sloan Digital Sky Survey. The simulation results are unanimous and unambiguous: quiescence in centrals and high-mass satellites is best predicted by intrinsic parameters (specifically central black hole mass), while it is best predicted by environmental parameters (specifically halo mass) for low-mass satellites. In observations, we find black hole mass to best predict quiescence for centrals and high-mass satellites, exactly as predicted by the simulations. However, local galaxy overdensity is found to be most predictive parameter for low-mass satellites. None the less, both simulations and observations do agree that it is environment which quenches low-mass satellites. We provide evidence which suggests that the dominance of local overdensity in classifying low-mass systems may be due to the high uncertainty in halo mass estimation from abundance matching, rather than it being fundamentally a more predictive parameter. Finally, we establish that the qualitative trends with environment predicted in simulations are recoverable in the observation space. This has important implications for future wide-field galaxy surveys.
Dust–gas dynamics driven by the streaming instability with various pressure gradients
Authors: Baronett Stanley A , Yang Chao-Chin , Zhu Zhaohuan 
Published: January 2024

ABSTRACT
The streaming instability, a promising mechanism to drive planetesimal formation in dusty protoplanetary discs, relies on aerodynamic drag naturally induced by the background radial pressure gradient. This gradient should vary in discs, but its effect on the streaming instability has not been sufficiently explored. For this purpose, we use numerical simulations of an unstratified disc to study the non-linear saturation of the streaming instability with mono-disperse dust particles and survey a wide range of gradients for two distinct combinations of the particle stopping time and the dust-to-gas mass ratio. As the gradient increases, we find most kinematic and morphological properties increase but not always in linear proportion. The density distributions of tightly coupled particles are insensitive to the gradient whereas marginally coupled particles tend to concentrate by more than an order of magnitude as the gradient decreases. Moreover, dust–gas vortices for tightly coupled particles shrink as the gradient decreases, and we note higher resolutions are required to trigger the instability in this case. In addition, we find various properties at saturation that depend on the gradient may be observable and may help reconstruct models of observed discs dominated by streaming turbulence. In general, increased dust diffusion from stronger gradients can lower the concentration of dust filaments and can explain the higher solid abundances needed to trigger strong particle clumping and the reduced planetesimal formation efficiency previously found in vertically stratified simulations.

Published: January 2024

ABSTRACT
Environmental effects on the formation and evolution of galaxies have been one of the leading questions in galaxy studies during the past few decades. In this work, we investigate the relationship between the star formation activity of galaxies and their environmental matter density using the cosmological hydrodynamic simulation Simba. The galactic star formation activity indicators that we explore include the star formation efficiency (SFE), specific star formation rate (sSFR), and molecular hydrogen mass fraction ($f^{*}_{\mathrm{H_2}}$), and the environment is considered as the large-scale environmental matter density, calculated based on the stellar mass of nearby galaxies on a 1 h−1 Mpc  grid using the cloud in cell method. Our sample includes galaxies with $9\lt \log \frac{M_*}{{\rm M}_{\odot }}$ at 0 &lt; z &lt; 4, divided into three stellar mass bins to disentangle the effects of stellar mass and environment on the star formation activity of galaxies. For low- to intermediate-mass galaxies at low redshifts (z &lt; 1.5), we find that the star formation efficiency of those in high-density regions are ∼0.3 dex lower than those in low-density regions. However, there is no significant environmental dependence of the star formation efficiency for massive galaxies over all our redshift range, and low- to intermediate-mass galaxies at high redshifts (z &gt; 1.5). We present a scaling relation for the depletion time of cold molecular hydrogen (tdepl = 1/SFE) as a function of galaxy parameters including environmental density. Our findings provide a framework for quantifying the environmental effects on the star formation activities of galaxies as a function of stellar mass and redshift. The most significant environmental dependence is seen at later cosmic times (z &lt; 1.5) and towards lower stellar masses ($9\lt \log \frac{M_*}{{\rm M}_{\odot }}\lt 10$). Future large galaxy surveys can use this framework to look for the environmental dependence of the star formation activity and examine our predictions.

ABSTRACT
Stellar chemical abundances have proved themselves a key source of information for understanding the evolution of the Milky Way, and the scale of major stellar surveys such as GALAH have massively increased the amount of chemical data available. However, progress is hampered by the level of precision in chemical abundance data as well as the visualization methods for comparing the multidimensional outputs of chemical evolution models to stellar abundance data. Machine learning methods have greatly improved the former; while the application of tree-building or phylogenetic methods borrowed from biology are beginning to show promise with the latter. Here, we analyse a sample of GALAH solar twins to address these issues. We apply The Cannon algorithm to generate a catalogue of about 40 000 solar twins with 14 high precision abundances which we use to perform a phylogenetic analysis on a selection of stars that have two different ranges of eccentricities. From our analyses, we are able to find a group with mostly stars on circular orbits and some old stars with eccentric orbits whose age–[Y/Mg] relation agrees remarkably well with the chemical clocks published by previous high precision abundance studies. Our results show the power of combining survey data with machine learning and phylogenetics to reconstruct the history of the Milky Way.
Are odd radio circles virial shocks around massive galaxies? Implications for cosmic-ray diffusion in the circumgalactic medium
Authors: Yamasaki Shotaro , Sarkar Kartick C , Li Zhaozhou 
Published: January 2024

ABSTRACT
Recently, a new population of circular radio (∼GHz) objects has been discovered at high Galactic latitudes, called the odd radio circles (ORCs). A fraction of the ORCs encircles massive galaxies in the sky with stellar mass ∼1011 M⊙ situated at z = 0.2–0.6, suggesting a possible physical connection. In this paper, we explore the possibility that these radio circles originate from the accretion shocks/virial shocks around massive (${\gtrsim} 10^{13}\, \ {\rm M}_\odot$) dark matter halo at z ∼ 0.5. We found that the radio flux density of the emitting shell is marginally consistent with the ORCs. We also find that pure advection of electrons from the shock results in a radio-emitting shell that is considerably narrower than the observed one due to strong inverse-Compton cooling of electrons. Instead, we show that the diffusion of cosmic-ray (CR) electrons plays a significant role in increasing the width of the shell. We infer a diffusion coefficient, $D_{\rm cr} \sim 10^{30}\ {\rm cm^2\, s^{-1}}$, consistent with the values expected for low-density circumgalactic medium (CGM). If ORCs indeed trace virial shocks, then our derived CR diffusion coefficient represents one of the few estimations available for the low-density CGM. Finally, we show that the apparent discrepancy between ORC and halo number density can be mitigated by considering an incomplete halo virialization and the limited radiation efficiency of shocks. This study therefore opens up new avenues to study such shocks and non-thermal particle acceleration within them. Furthermore, our results suggest that low-mass galaxies (≲1013 M⊙) may not show ORCs due to their significantly lower radio surface brightness.
MaNGA AGN dwarf galaxies (MAD) – I. A new sample of AGNs in dwarf galaxies with spatially-resolved spectroscopy
Authors: Mezcua M , Sánchez H Domínguez 
Published: January 2024

ABSTRACT
The finding of active galactic nuclei (AGNs) in dwarf galaxies has important implications for galaxy evolution and supermassive black hole formation models. Yet, how AGNs in dwarf galaxies form is still debated, in part due to scant demographics. We use the MaNGA survey, comprising ∼10 000 galaxies at z &lt; 0.15, to identify AGN dwarf galaxies using a spaxel-by-spaxel classification in three spatially-resolved emission-line diagnostic diagrams (the [N ii]-, [S ii]-, and [O i]-BPT) and the WHAN diagram. This yields a sample of 664 AGN dwarf galaxies, the largest to date, and an AGN fraction of $\sim 20~{{\ \rm per\ cent}}$ that is significantly larger than that of single-fibre-spectroscopy studies (i.e. $\sim 1~{{\ \rm per\ cent}}$). This can be explained by the lower bolometric luminosity (&lt;1042 erg s−1) and accretion rate (sub-Eddington) of the MaNGA AGN dwarf galaxies. We additionally identify 1176 SF-AGNs (classified as star-forming in the [N ii]-BPT but as AGNs in the [S ii]- and [O i]-BPT), 122 Composite, and 173 LINER sources. The offset between the optical centre of the galaxy and the median position of the AGN spaxels is more than 3 arcsec for ∼62% of the AGNs, suggesting that some could be off-nuclear. We also identify seven new broad-line AGNs with log MBH = 5.0–5.9 M⊙. Our results show how integral-field spectroscopy is a powerful tool for uncovering faint and low-accretion AGNs and better constraining the demographics of AGNs in dwarf galaxies.
A global survey of small RNA interactors identifies KhpA and KhpB as major RNA-binding proteins in Fusobacterium nucleatum
Authors: Zhu Yan , Ponath Falk , Cosi Valentina , Vogel Jörg 
Published: January 2024

Abstract
The common oral microbe Fusobacterium nucleatum has recently drawn attention after it was found to colonize tumors throughout the human body. Fusobacteria are also interesting study systems for bacterial RNA biology as these early-branching species encode many small noncoding RNAs (sRNAs) but lack homologs of the common RNA-binding proteins (RBPs) CsrA, Hfq and ProQ. To search for alternate sRNA-associated RBPs in F. nucleatum, we performed a systematic mass spectrometry analysis of proteins that co-purified with 19 different sRNAs. This approach revealed strong enrichment of the KH domain proteins KhpA and KhpB with nearly all tested sRNAs, including the σE-dependent sRNA FoxI, a regulator of several envelope proteins. KhpA/B act as a dimer to bind sRNAs with low micromolar affinity and influence the stability of several of their target transcripts. Transcriptome studies combined with biochemical and genetic analyses suggest that KhpA/B have several physiological functions, including being required for ethanolamine utilization. Our RBP search and the discovery of KhpA/B as major RBPs in F. nucleatum are important first steps in identifying key players of post-transcriptional control at the root of the bacterial phylogenetic tree.
