AbstractFossil fuels helped Russian president Putin build military power of Russia and attack Ukraine. Coal, gas and oil are being used by Putin’s regime as weapons against the countries that are contractors and consumers of Russian fuels.The aim of this paper is to present a methodology based on refining information and Big Data analysis and to demonstrate the results, as well as to show trends and developments in relation to the response to the crisis on the fossil fuel market. Predictive methods and the techniques of sentiment analysis including the cluster analysis and the analysis of the variability of trends indicates that the European Union has taken over the burden of energy policy-making. This also indicates a downgrading of national policies and their weakness in resisting Russia’s aggressive actions. The analysis of frequency confirms the markedly different Russian attitudes to Europe as a whole and to its individual members.
State of the art of metal powder bonded binder jetting printing technology
Authors: Fang Xiaotong , Zu Yu , Ma Qing , Hu Jing 
Published: June 2023

AbstractAs one of the earlier developed additive manufacturing (AM) technologies, binder jetting (BJT) has the advantages of low cost, high efficiency and no pollution. This article focuses on the research status and problems of BJT printing materials and printing technology. BJT technology can print metal parts with complex structures, which is widely used in medical, aerospace and other fields. The particle size and morphology of the raw powder, the saturation of the binders and the area of the pores size will affect the bonding of the powder bed. In the printing processes, the thickness, orientation and printing speed will affect the mechanical properties of the printed parts. The post-treatment processing has the greatest influence on the mechanical properties of the final parts. Sintering and infiltration can improve the mechanical strength of the parts. Mechanical grinding, such as polishing and grinding, can affect the surface roughness of parts. Selecting suitable technological parameters for different characteristics of materials is particularly important for the future development of BJT printing.
A world beyond self: empathy and pedagogy during times of global crisis
Authors: Gates Eliza , Curwood Jen Scott 
Published: June 2023

AbstractA significant body of research points to the benefits of empathy for young people’s personal, social, and educational development. However, some research indicates that youth empathy levels are declining. The COVID-19 pandemic has provided a unique opportunity to research empathy in education during times of global crisis and local educational disruption. This study explored Australian English teachers’ beliefs, pedagogical approaches, and experiences in relation to teaching with, for, and about empathy, including during the pandemic. Drawing from a state-wide survey and representative teacher case studies, this study revealed a couple key findings. First, the majority of participants recognised the value of empathy for student learning and engagement; however, teachers disagreed on whether empathy impacts academic performance. Second, teachers tended to avoid teaching explicitly about empathy because they felt it was not prescribed in the English Syllabus. Each of these findings was underpinned by a tension between teacher beliefs about the value of empathy in learning and the limitations of including empathy in English education due to curriculum mandates and assessment requirements.
Social role effects on English particle verb variation fail to replicate
Authors: Lee Naomi , Mackenzie Laurel 
Published: June 2023

AbstractThe English particle verb alternation has been argued to be sensitive to the social role occupied by speakers on radio broadcasts; Kroch and Small (1978) argue that radio show hosts and in-studio guests’ greater sensitivity to prescriptive norms makes them more likely to use the joined variant of the alternation than listeners calling in to the show. This study analyzes 10,521 tokens of variable particle verbs from the RadioTalk Corpus (Beeferman et al. 2019) to try to replicate the effect of speaker role. Our analysis confirms that direct object length, register, a measure of frequency, semantic compositionality of the particle verb, and the particle's prosody all condition the alternation. However, the effect of social role does not replicate.
Doing Good with Words: The Virtue of Benevolent Persuasiveness
Authors: Campos Veronica 
Published: June 2023

AbstractContemporary virtue epistemology has been progressing remarkably in the activity of virtue profiling, yet a lot remains to be discussed about the many ways and extents to which some virtues and vices of the intellect impact our lives. This paper is an attempt at sketching a preliminary profile to an epistemic virtue that hasn't received a lot of attention to this date: the virtue of being a good convincer, aka persuasiveness. I submit that there is a particular way of using speech in which persuasiveness is allied with benevolence as a means of conveying a distinctive type of epistemic good, the good of understanding.
La identidad cultural de Pahñú: Análisis de la arquitectura del período clásico de un centro ceremonial en el valle del Mezquital
Authors: Sandoval Gustavo 
Published: June 2023

ResumenEste artículo analiza la arquitectura del período Clásico de Pahñú, un centro ceremonial en el noreste del valle del Mezquital, México. Esta arquitectura se distingue porque desarrolló un estilo local, integrando elementos de distintas tradiciones culturales. Por un lado, los conjuntos arquitectónicos de patio hundido siguen los estándares de la tradición del Bajío. Por otra parte, los edificios muestran rasgos de la arquitectura monumental teotihuacana y zapoteca. A partir de esta evidencia se concluye que Pahñú definió su identidad étnica estableciendo filiaciones políticas con las culturas del centro y el Bajío. Esta interpretación pone a prueba varias explicaciones previas que conciben el desarrollo regional durante el período Clásico como aculturación o resistencia a Teotihuacán. Asimismo, pone a prueba las interpretaciones que sostienen que la fusión cultural entre los grupos del centro y el Bajío comenzó hasta el Epiclásico. Finalmente, Pahñú es importante porque representa un pequeño centro político que mantuvo su liderazgo por unos seiscientos años, aprovechando su posición fronteriza entre el centro y el Bajío.
Pucara Hilltop Settlements in the Lupaca and Pacajes Territories, Southern Andean Altiplano, during the Late Intermediate Period (AD 1000–1450)
Authors: Housse Romuald , Mouquet Arthur 
Published: June 2023

AbstractThe quantity of archaeological data for the fortified hilltop settlements of the Late Intermediate period on the Andean altiplano, called pucaras, varies greatly. Some areas, such as the territory of the Colla Aymara chieftaincy east of Lake Titicaca, are well documented thanks to recent and exhaustive research. Other areas, such as the territories of the Lupacas and the Pacajes, are much less documented. From comparative spatial analyses of satellite images from these two territories, we obtained new data on pucaras, whose characteristics seem to differ from those proposed in the archaeological literature. Through a combination of fieldwork and spatial analysis of 295 pucaras, we identified 252 unpublished sites and propose a new typology comprising four categories. Based on ethnohistoric data and the results of the architectural and geographical analyses, we discuss the possible motivations for building so many pucaras; we suggest that some reasons are of a symbolic nature.
The Persistent Power of Cultural Racism
Authors: Alcoff Linda Martín 
Published: June 2023

Abstract‘Cultural racism’ is central to understanding racism today yet has receded into the background behind the focus on attitudinal racism. Even the turn to structural racism is largely circumscribed to inclusion without substantive challenge to existing processes or profit margins. When portions of the racist public are targeted, it is often the least elite members of society. Without question, the concept of cultural racism requires some clarification, but it will help bring the continued influence of colonialism forward and reveal the alibis given in mainstream and elite circles that justify exclusion, resource extraction, and domination.
Effects of Landslides on Terrestrial Carbon Stocks With a Coupled Geomorphic‐Biologic Model: Southeast Alaska, United States
Authors: Booth A. M. , Buma B. , Nagorski S. 
Published: June 2023

AbstractLandslides influence the global carbon (C) cycle by facilitating transfer of terrestrial C in biomass and soils to offshore depocenters and redistributing C within the landscape, affecting the terrestrial C reservoir itself. How landslides affect terrestrial C stocks is rarely quantified, so we derive a model that couples stochastic landslides with terrestrial C dynamics, calibrated to temperate rainforests in southeast Alaska, United States. Modeled landslides episodically transfer C from scars to deposits and destroy living biomass. After a landslide, total C stocks on the scar recover, while those on the deposit either increase (in the case of living biomass) or decrease while remaining higher than if no landslide had occurred (in the case of dead biomass and soil C). Specifically, modeling landslides in a 29.9 km2 watershed at the observed rate of 0.004 landslides km−2 yr−1 decreases average living biomass C density by 0.9 tC ha−1 (a relative amount of 0.4%), increases dead biomass C by 0.3 tC ha−1 (0.6%), and increases soil C by 3.4 tC ha−1 (0.8%) relative to a base case with no landslides. The net effect is a small increase in total terrestrial C stocks of 2.8 tC ha−1 (0.4%). The size of this boost increases with landslide frequency, reaching 6.5% at a frequency of 0.1 landslides km−2 yr−1. If similar dynamics occur in other landslide‐prone regions of the globe, landslides should be a net C sink and a natural buffer against increasing atmospheric CO2 levels, which are forecast to increase landslide‐triggering precipitation events.

AbstractWe characterize the precipitating electrons accelerated in the Europa‐magnetosphere interaction by analyzing in situ measurements and remote sensing observations recorded during 10 crossings of the flux tubes connected to Europa's auroral footprint tail by Juno. The electron downward energy flux, ranging from 34 to 0.8 mW/m2, exhibits an exponential decay as a function of downtail distance, with an e‐folding factor of 7.4°. Electrons are accelerated at energies between 0.3 and 25 keV, with a characteristic energy that decreases downtail. The electron distributions form non‐monotonic spectra in the near tail (i.e., within an angular separation of less than 4°) that become broadband in the far tail. The size of the interaction region at the equator is estimated to be 4.2 ± 0.9 Europa radii, consistent with previous estimates based on theory and UV observations.

Published: June 2023

AbstractSubglacial hydrology can exert an important control on ice flow by affecting friction at the ice‐bedrock interface. Here, we report on a series of subglacial drainage events along the Northeast Greenland Ice Stream (NEGIS), initiating as far inland as 500 km from the margin of Zachariae Isstrøm. The drainage events exhibit local transient uplift, followed by prolonged subsidence, measured by differential satellite synthetic aperture radar interferometry (DInSAR). In downstream regions, drainage events are associated with temporary acceleration in ice flow. The high spatiotemporal resolution of the DInSAR measurements allows for a detailed mapping of the drainage propagation pathway. We show that multiple drainage cascades have occurred along the same pathway over the years 2020–2022. Finally, the propagation speed of subglacial water flow is found to vary greatly along NEGIS, suggesting that fundamental differences could exist in the subglacial environment.
On the Impact of Thermal Gradients Across Fluxgate Sensors on In Situ Magnetic Field Measurements
Authors: Greene K. , Hansen C. T. , Miles D. M. 
Published: June 2023

AbstractFluxgate magnetometers are an important tool for measuring space plasmas. In situ magnetic field investigations often involve measuring small perturbations of a large background field, so robust instrument calibration is critical to accurately resolving geophysical signals. Fluxgate instruments aboard recent space science missions have observed calibration anomalies that have been attributed to thermal gradients across the sensor. Here we present data from a laboratory experimental investigation of effects of thermal gradients on fluxgate calibration and performance. A purpose‐built laboratory apparatus fixed two thermal reservoirs at either end of a racetrack fluxgate sensor. Varying the reservoir temperatures allowed us to vary the sensor temperature and impose thermal gradients as large as 50°C across a racetrack fluxgate sensor. We find that changes in instrumental sensitivity, offset, and noise can be explained purely by changes in the average temperature of the sensor without a dependence on the difference in temperature across the sensor. We suggest that invoking concept of a static thermal gradient inducing thermoelectric currents within the fluxgate core or sensor may not be appropriate to explain changes in instrumental sensitivity, offset, and noise that have been observed on orbit.

Published: June 2023

AbstractLarge-area lasers are practical for generating high output powers. However, this often comes at the expense of lower beam quality due to the introduction of higher-order modes. Here, we experimentally demonstrate a new type of electrically pumped, large-area edge-emitting lasers that exhibit a high power emission (∼0.4 W) and a high-quality beam (M2∼1.25). These favorable operational characteristics are enabled by establishing a quasi PT-symmetry between the second-order mode of a large area two-mode laser cavity and that of a single-mode auxiliary partner cavity, i.e., by implementing a partial isospectrality between the two coupled cavities. This in turn enlarges the effective volume of the higher-order modes. As a result, a selective pump applied via current injection into the main laser cavity can provide a stronger modal gain to the fundamental mode, and thus lead to lasing in the single mode regime after filtering out higher order transverse modes. The reported experimental results confirm this intuitive picture and are in good agreement with both theoretical and numerical analysis. Above all, the employed material platform and fabrication process are compatible with the industrial standards of semiconductor lasers. This work provides the first clear demonstration, beyond previous proof-of-concept studies, of the utility of PT-symmetry in building laser geometries with enhanced performance and, at the same time, useful output power levels and emission characteristics.

Abstract
After decades studying the microbial “deep biosphere” in subseafloor oceanic crust, the growth and life strategies in this anoxic, low energy habitat remain poorly described. Using both single cell genomics and metagenomics, we reveal the life strategies of two distinct lineages of uncultivated Aminicenantia bacteria from the basaltic subseafloor oceanic crust of the eastern flank of the Juan de Fuca Ridge. Both lineages appear adapted to scavenge organic carbon, as each have genetic potential to catabolize amino acids and fatty acids, aligning with previous Aminicenantia reports. Given the organic carbon limitation in this habitat, seawater recharge and necromass may be important carbon sources for heterotrophic microorganisms inhabiting the ocean crust. Both lineages generate ATP via several mechanisms including substrate-level phosphorylation, anaerobic respiration, and electron bifurcation driving an Rnf ion translocation membrane complex. Genomic comparisons suggest these Aminicenantia transfer electrons extracellularly, perhaps to iron or sulfur oxides consistent with mineralogy of this site. One lineage, called JdFR-78, has small genomes that are basal to the Aminicenantia class and potentially use “primordial” siroheme biosynthetic intermediates for heme synthesis, suggesting this lineage retain characteristics of early evolved life. Lineage JdFR-78 contains CRISPR-Cas defenses to evade viruses, while other lineages contain prophage that may help prevent super-infection or no detectable viral defenses. Overall, genomic evidence points to Aminicenantia being well adapted to oceanic crust environments by taking advantage of simple organic molecules and extracellular electron transport.

AbstractThe immune-excluded tumors (IETs) show limited response to current immunotherapy due to intrinsic and adaptive immune resistance. In this study, it is identified that inhibition of transforming growth factor-β (TGF-β) receptor 1 can relieve tumor fibrosis, thus facilitating the recruitment of tumor-infiltrating T lymphocytes. Subsequently, a nanovesicle is constructed for tumor-specific co-delivery of a TGF-β inhibitor (LY2157299, LY) and the photosensitizer pyropheophorbide a (PPa). The LY-loaded nanovesicles suppress tumor fibrosis to promote intratumoral infiltration of T lymphocytes. Furthermore, PPa chelated with gadolinium ion is capable of fluorescence, photoacoustic and magnetic resonance triple-modal imaging-guided photodynamic therapy, to induce immunogenic death of tumor cells and elicit antitumor immunity in preclinical cancer models in female mice. These nanovesicles are further armored with a lipophilic prodrug of the bromodomain-containing protein 4 inhibitor (i.e., JQ1) to abolish programmed death ligand 1 expression of tumor cells and overcome adaptive immune resistance. This study may pave the way for nanomedicine-based immunotherapy of the IETs.

AbstractIn recent years, correlated insulating states, unconventional superconductivity, and topologically non-trivial phases have all been observed in several moiré heterostructures. However, understanding of the physical mechanisms behind these phenomena is hampered by the lack of local electronic structure data. Here, we use scanning tunnelling microscopy and spectroscopy to demonstrate how the interplay between correlation, topology, and local atomic structure determines the behaviour of electron-doped twisted monolayer–bilayer graphene. Through gate- and magnetic field-dependent measurements, we observe local spectroscopic signatures indicating a quantum anomalous Hall insulating state with a total Chern number of ±2 at a doping level of three electrons per moiré unit cell. We show that the sign of the Chern number and associated magnetism can be electrostatically switched only over a limited range of twist angle and sample hetero-strain values. This results from a competition between the orbital magnetization of filled bulk bands and chiral edge states, which is sensitive to strain-induced distortions in the moiré superlattice.

AbstractHund’s rule coupling (J) has attracted much attention recently for its role in the description of the novel quantum phases of multi-orbital materials. Depending on the orbital occupancy, J can lead to various intriguing phases. However, experimental confirmation of the orbital occupancy dependency has been difficult as controlling the orbital degrees of freedom normally accompanies chemical inhomogeneities. Here, we demonstrate a method to investigate the role of orbital occupancy in J related phenomena without inducing inhomogeneities. By growing SrRuO3 monolayers on various substrates with symmetry-preserving interlayers, we gradually tune the crystal field splitting and thus the orbital degeneracy of the Ru t2g orbitals. It effectively varies the orbital occupancies of two-dimensional (2D) ruthenates. Via in-situ angle-resolved photoemission spectroscopy, we observe a progressive metal-insulator transition (MIT). It is found that the MIT occurs with orbital differentiation: concurrent opening of a band insulating gap in the dxy band and a Mott gap in the dxz/yz bands. Our study provides an effective experimental method for investigation of orbital-selective phenomena in multi-orbital materials.

AbstractQuantum key distribution with solid-state single-photon emitters is gaining traction due to their rapidly improving performance and compatibility with future quantum networks. Here we emulate a quantum key distribution scheme with quantum-dot-generated single photons frequency-converted to 1550 nm, achieving count rates of 1.6 MHz with $${g}^{\left(2\right)}\left(0\right)=3.6\%$$

and asymptotic positive key rates over 175 km of telecom fibre. We show that the commonly used finite-key analysis for non-decoy state QKD drastically overestimates secure key acquisition times due to overly loose bounds on statistical fluctuations. Using the tighter multiplicative Chernoff bound to constrain the estimated finite key parameters, we reduce the required number of received signals by a factor 108. The resulting finite key rate approaches the asymptotic limit at all achievable distances in acquisition times of one hour, and at 100 km we generate finite keys at 13 kbps for one minute of acquisition. This result is an important step towards long-distance single-emitter quantum networking.
