Current trends point to a not-too-distant future with qualitatively advanced interactions between humans and social robots. It is critical to consider the possibility of forming meaningful social relationships with robots when defining the future of human-robot interactions, as well as studying how these interactions will evolve to the point where humans are unable to distinguish between humans and robots in urban transportation. In this study, the advantages of using social robots in urban transportation are prioritized by using a multi-criteria decision-making tool, which consists of two consecutive stages, namely: i) a novel fuzzy sine trigonometry based on the logarithmic method of additive weights (fuzzy ST-LMAW) that is proposed to calculate the criteria weights;ii) a nonlinear fuzzy Aczel-Alsina function based the weighted aggregate sum product assessment (fuzzy ALWAS-WASPAS) that is developed to select and rank the alternatives. The proposed model enables flexible nonlinear processing of complex and uncertain information encountered in real applications. A case study is developed to rank three alternatives with twelve sub-criteria grouped into four aspects using the proposed method. The results show that the most advantageous alternative is to replace people with social robots as safety drivers in level four autonomous vehicles due to their possible impact on transportation. © 2023 The Authors

We have studied the Co layer thickness dependences of magnetocrystalline anisotropy (MCA), Dzyaloshinskii-Moriya interaction (DMI), and orbital moment anisotropy (OMA) in W/Co/Pt trilayers, in order to clarify their correlations with each other. We find that the MCA favors magnetization along the film normal and monotonically increases with decreasing effective magnetic layer thickness (teff). The magnitude of the Dzyaloshinskii-Moriya exchange constant (|D|) increases with decreasing teff until teff ∼1 nm, below which |D| decreases. The MCA and |D| scale with 1/teff for teff larger than ∼1 nm, indicating an interfacial origin. The increase of MCA with decreasing teff continues below teff ∼ 1 nm, but with a slower rate. To clarify the cause of the teff dependences of MCA and DMI, the OMA of Co in W/Co/Pt trilayers is studied using x-ray magnetic circular dichroism (XMCD). We find non-zero OMA when teff is smaller than ∼0.8 nm. The OMA increases with decreasing teff more rapidly than what is expected from the MCA, indicating that factors other than OMA contribute to the MCA at small teff. The teff dependence of the OMA also suggests that |D| at teff smaller than ∼1 nm is not related to the OMA at the interface. We propose that the growth of Co on W results in a strain and/or texture that reduces the interfacial DMI, and, to some extent, MCA at small teff © 2021, CC BY.

Carbodicarbene (CDC) has become an emerging ligand in many fields due to its strong σ-donating ability. 2- moiety within the framework to leverage the electronic feature of carbon carbone. The elucidation of X-ray crystal structures, ligand competition as well as transmetallation experiments suggest that the anionic moiety has enhanced the overall donor strength of the traditional neutral CDC. Importantly, this anionic scaffold exhibits a facile second coordination toward Au(I), Ag(I) and Pd(II) without any external ligand assistance, whereas previously reported neutral pincer CDC complexes do not possess a two-fold donor capacity. The analysis of the bonding situation via theoretical methods shows that the description of the anionic CDC moieties in terms of dative bonding is preferred over the model of delocalized positive charge, as it accounts for the two-fold donor ability of the divalent carbon atom, preserving a characteristic feature of a carbone. © 2023 Wiley-VCH GmbH.

The timing, rate, and magnitude of rapid sea-level rise during Meltwater Pulse 1B (MWP-1B, ~11.45–11.1 ka) remain controversial. Robust constraints on past MWPs are crucial to future predictions of global ice sheet instability. Using 154 new and existing U/Th and calibrated ¹⁴C-AMS dates from coral, algae, and microbialites recovered during Integrated Ocean Drilling program Expedition 325, this study reconstructs reef development and relative sea-level (RSL) rise on the Great Barrier Reef (GBR). We identify 107 in situ RSL index points while refining estimates of vertical accretion and paleowater depth. Results show RSL rise during MWP-1B did not exceed 10.2–7.7 m or rates of 30–23 mm/yr, and was likely less. The GBR did not drown, indicating resilience to MWP-1B. These findings are more consistent with Tahiti and other Pacific records and do not support the Barbados record of MWP-1B as an abrupt step in global sea level, with a magnitude > 11 m. © The Author(s) 2025.

Preparation and mitigation efforts for widespread landslide hazards can be aided by a large-scale, well-labeled landslide inventory with high location accuracy. Recent small-scale studies for pixel-wise labeling of potential landslide areas in remotely-sensed images using deep learning (DL) showed potential but were based on data from very small, homogeneous regions with unproven model transferability. In this paper we consider a more realistic and practical setting for large-scale heterogeneous landslide data collection and DL-based labeling. In this setting, remotely sensed images are collected sequentially in temporal batches, where each batch focuses on images from a particular ecoregion, but different batches can focus on different ecoregions with distinct landscape characteristics. For such a scenario, we study the following questions: (1) How well do DL models trained in homogeneous regions perform when they are transferred to different ecoregions, (2) Does increasing the spatial coverage in the data improve model performance in a given ecoregion (even when the extra data do not come from the ecoregion), and (3) Can a landslide pixel labeling model be incrementally updated with new data, but without access to the old data and without losing performance on the old data (so that researchers can share models obtained from proprietary datasets)? We address these questions by extending the Learning without Forgetting framework, which is used for incremental training of image classification models, to the setting of incremental training of semantic segmentation models (e.g., identifying all landslide pixels in an image). We call the resulting extension Task-Specific Model Updates (TSMU). The goal of this framework is to continually update a (landslide) semantic segmentation model with data from new ecoregions without having to revisit data from old ecoregions and without losing performance on them. Using the TSMU framework, we conduct extensive experiments on four

Scalable metagrating for efficient ultrasonic focusing

Acoustic focusing plays a pivotal role in a wide variety of applications ranging from medical science to nondestructive testing. Previous works have shown that acoustic metagratings can overcome the inherent efficiency limitations of gradient metasurfaces in beam steering. In this work, we propose a new design principle for acoustic metalenses, based on metagratings, to achieve efficient ultrasonic focusing. We achieve beam focusing by locally controlling the excitation of a single diffraction order with the use of adiabatically varying metagratings over the lens aperture. A set of metagratings is optimized by a semi-analytical approach using a genetic algorithm, enabling efficient anomalous reflection for a wide range of reflection angles. Numerical results reveal that our metalens can effectively focus impinging ultrasonic waves to a focal point of FWHM = 0.364λ. The focusing performance of the metalens is demonstrated experimentally, validating our proposed approach. © 2021, CC BY.

Adsorption Mechanisms of Ethanol, Propanal, Butanone, and Benzene on the Monolayer WS₂ Surface: Insights from non-local van der Waals Density Functional Theory

This study examines the adsorption mechanisms of ethanol, propanal, butanone, and benzene, which represent four typical functional groups-alcohol, aldehyde, ketone, and aromatic-on the monolayer WS 2 surface using the non-local van der Waals density functional theory. The results indicate that all four gases exhibit physical adsorption on the WS₂ surface. The adsorption is primarily governed by van der Waals interactions between the gas molecules and the WS₂ substrate. Among the studied gases, butanone demonstrates the highest charge transfer (0.36 e) due to the strong polarity of the ketone functional group (-C=O). This significant charge transfer not only enhances the interaction between the gas and the WS₂ substrate but also improves the sensor's sensitivity by inducing pronounced changes in the electronic properties of WS₂. Benzene, an aromatic compound, exhibits the highest adsorption energy (637 meV), reflecting the strong π-π interactions between its aromatic ring and the WS₂ surface. This makes benzene the most stable adsorbate among the gases studied, highlighting its potential for detecting aromatic compounds in sensor applications. The results could provide new prospects for the use of WS 2 in high-performance sensing devices.
