Native flora receive more visits than exotics from bees, especially native bees, in an urbanised biodiversity hotspot
Authors: Prendergast Kit S. 
Published: June 2023

Context Identifying floral resources preferred by bee assemblages is important for their conservation. Aims Here, I assess the association of flowering plant community composition, with that of honey bees and native bee abundance and diversity. I investigate flower preferences in terms of plant origin (native or exotic), and evaluate niche breadth, of introduced honey bees and native bee taxa. I also consider if habitat influences these patterns. Methods This was evaluated through recording flower visitation by honey bees and native bees in the urbanised region of the south-west Western Australian Floristic Region in seven bushland remnants and seven residential gardens over 2 years. Key results Both native bees and honey bees visited more native than exotic flora, however native bees visited a higher proportion of native flora than honey bees. The 10-most visited plants by native bees were exclusively native, whereas for honey bees, although their 10-most visited plants were predominantly native plant species, this selection also included exotic plant species. Niche breadth was broader in bushland remnants, indicating a greater range of preferred flora in bushland remnants. Honey bees however visited more plant families in residential gardens. With increased honey bee abundance, this was associated with native bees expanding their niche breadth, which may be a response to reduce competition. Flower preference patterns and niche breadth often differed between habitats, indicating that foraging patterns may be mediated by habitat context. Conclusion Native flora are preferred by bees, and native bees have relatively restricted flower preferences, especially compared with honey bees. Implications High proportions of preferred native flora are needed to support diverse native bee assemblages in urban areas.
Capturing meaningful generalizations at varying degrees of resolution

Published: June 2023

Abstract
This article provides a principled constructionist account (Goldberg &
Herbst, 2021) of the main characteristics of expressions like the following: (1) Juan es muy de (ir de)
bares (‘Juan is very into (going to) bars’), and (2) Tu ayuda es muy de agradecer (‘Your help is
very much appreciated’). Instances of this kind are best handled in terms of coercion between the intensifier and
non-stative/non-gradable elements in the nominal slot of the de-PPs. Specifically, these combinations qualify as
individual-level predicates with a characterizing, evaluative interpretation. The specific constructional interpretations in
(1)–(2) arise from contextual adjustments (Carston, 2015), encoding a person’s habits and a potential modal deontic habituality,
respectively. The semantic and pragmatic properties of the sub-constructions in (1)–(2), among others, can be adequately subsumed under a family of ser muy de-PP
constructions, with the following general meaning: ‘X (SOMEONE/SOMETHING) (SUBJECT) IS SUBJECTIVELY CONSTRUED AS HAVING Y (A
HIGHLIGHTED CLASSIFICATORY PROPERTY OF AN INDIVIDUAL/CLASS) (ATTRIBUTE)’.

Published: June 2023

Abstract

Experiences of positive affect (PA) are common when interacting with animals and may help to build resilience. This study explored how children’s relationships with pet dogs, parents, and friends are related to their experiences of PA with their pet dog. In addition, we examined whether greater PA with pet dogs was related to children’s thriving. The sample (
n
= 115, 57 girls, 58 boys) included children 9–14 years of age who reported the quality of relationships with their pet dog (Positive Relationship Qualities, Friction, Pets as Substitutes), attachment security to parents, and positive and negative friendship quality. PA was assessed with child self-report before and after interacting with their dog, observed child and dog PA during the interaction, and reports of daily PA when interacting with the dog from a 7-day daily log. Children completed questionnaires to assess attachment security relationship with parents and friendship relationship quality. Children’s relationships with parents and friends were related to PA in the interaction session, whereas relationships with pet dogs, parents, and friends were all related to the daily experiences of PA. Children’s experiences of PA in daily interactions with pet dogs, parent-child attachment, and positive friendship quality were all related to children’s thriving. The findings suggest that experiences of PA may be one mechanism that accounts for the effects of animals on children’s development.

Abstract

Plasmodium knowlesi
malaria is a vector-borne disease transmitted by the
Anopheles
mosquito. The incidence of this zoonotic malaria in South-east Asian rural communities continues to increase annually, despite efforts and guidelines for malaria control. To address this gap, a One Health project, supported by various stakeholders, was conducted from January to August 2022 to integrate community perspectives and address challenges to malaria prevention. The project implemented a photovoice initiative in collaboration with Universiti Kebangsaan Malaysia, Universiti Malaysia Sabah, international malaria experts, the Sabah State Health Department, and primary healthcare workers in four rural villages in Sabah, Malaysia. The study recruited 26 adult participants of both genders to explore their perceptions of malaria, prevention challenges, and the significance of innovative community engagement methods. Cultural and social norms, environmental factors, social disparity, and socio-economic status influenced the identified challenges. The project findings were shared with stakeholders and policy makers through photo exhibitions, newspaper articles, academic manuscripts, reports, and conferences and helped initiate further dialogues with policy makers and stakeholders. The transdisciplinary photovoice approach showcased the impact of collaborative efforts with rural communities in shedding light on critical issues related to malaria prevention. Future recommendations propose co-designing interventions for the target population and bridging the gap through a One Health initiative that integrates community perspectives and is supported by multiple stakeholders in addressing the challenges of malaria prevention.

Authors: Lemelin Raynald Harvey , Caveny John , Patton III H. 
Published: June 2023

Summary
Written by managers from Grandfather Mountain Stewardship Foundation, a not-for-profit natural park located in Linville, North Carolina, and a researcher specializing in entomotourism, a specialized form of wildlife tourism, this case study outlines how a wildlife viewing strategy for bioluminescent insects (e.g. fireflies, glow-worms) was developed and implemented in the summer of 2022. Capped at an attendance of 300 participants per night and requiring a pre-online registration, the three separate outings held in the summer of 2022 provided participants with opportunities to view bioluminescent insects. The designated viewing area consisted of a 321 m or 0.2 mi long paved road bordered by woods and one open area. In order to minimize the disruption to the fireflies’ mating patterns, participants were encouraged to use red-light flashlights, and staff were outfitted with the fluorescent vest. Participant discussions typically ended when the fireflies became active around dusk. Consisting of field observations and informal discussions with staff and some participants, and post-viewing reflections by the co-authors, the results provide an overview of bioluminescent insect viewing opportunities in the Grandfather Mountain Stewardship Foundation nature park while also examining the role of interpretive strategies. The conclusion highlights the key findings while providing future research and management strategies.

Summary

This case study examines an intersecting legacy of exclusion in the Welsh mountains, UK, and how this is challenged by Welsh women’s participation in outdoor adventure courses. The research critically appraised how Indigenous Welsh women
1
navigate gender, class, and racial landscapes in mountain leisure to create inclusive spaces. Facilitated by a National Charitable Organization (NCO) that engages Indigenous Welsh communities in mountain adventure, we explored women’s embodied experiences through mobile video ethnography. Methodologically embodiment facilitated a way of capturing bodily sensations and experiences, which provided a language to express those ideas through reflexive analysis (
Ellingson, 2017
). The findings highlight how women embody cultural identity in the mountains, which contributes to understanding issues of exclusion/inclusion in adventure spaces.

Fingerprint of parity anomaly for localized magnetic states in quantum anomalous Hall systems
Authors: Zhang Shi-Jie , Zhang Yun , Ding Kai-He 
Published: June 2023

Abstract
We investigate the local magnetic states of impurities in quantum anomalous Hall (QAH) systems and observe that with an increasing band gap, the magnetic region of impurities expands in the QAH phase, while it contracts in the ordinary insulator (OI) phase. During the transition between the QAH and the OI phase, the magnetization area undergoes a significant transformation from a broad region to a narrow strip, which serves as a distinctive characteristic of the parity anomaly in the localized magnetic states. Furthermore, the presence of the parity anomaly leads to notable alterations in the dependence of the magnetic moment and magnetic susceptibility on the Fermi energy. Additionally, we analyze the spectral function of the magnetic impurity as a function of Fermi energy for both the QAH and OI phases.

Published: June 2023

Abstract
Following defocused ion beam sputtering, large area highly corrugated and faceted nanoripples are formed on calcite (10.4) faces in a self-organized fashion. High resolution atomic force microscopy (AFM) imaging reveals that calcite ripples are defined by facets with highly kinked (11.0) and (2

.12) terminations. In situ AFM imaging during the exposure of such modified calcite surfaces to PbCl2 aqueous solution reveals that the nanostructured calcite surface promotes the uptake of Pb. In addition, we observed the progressive smoothing of the highly reactive calcite facet terminations and the formation of Pb-bearing precipitates elongated in registry with the underlying nanopattern. By SEM–EDS analysis we quantified a remarkable 500% increase of the Pb uptake rate, up to 0.5 atomic weight % per hour, on the nanorippled calcite in comparison to its freshly cleaved (10.4) surfaces. These results suggest that nanostructurated calcite surfaces can be used for developing future systems for lead sequestration from polluted waters.
Thin and thick bubble walls. Part I. Vacuum phase transitions
Authors: Mégevand Ariel , Membiela Federico Agustín 
Published: June 2023

Abstract
This is the first in a series of papers where we study the dynamics
of a bubble wall beyond usual approximations, such as the assumptions
of spherical bubbles and infinitely thin walls. In this paper, we
consider a vacuum phase transition. Thus, we describe a bubble as
a configuration of a scalar field whose equation of motion depends only
on the effective potential.
The thin-wall approximation allows obtaining both
an effective equation of motion for the wall position and
a simplified equation for the field profile inside the wall.
Several different assumptions are involved in this approximation.
We discuss the conditions for the validity of each of them.
In particular, the minima of the effective potential must
have approximately the same energy, and we discuss the correct implementation of this approximation.
We consider different improvements to the basic thin-wall approximation,
such as an iterative method for finding the wall profile
and a perturbative calculation in powers of the wall width.
We calculate the leading-order corrections.
Besides, we derive an equation of motion for the wall without any assumptions about its shape.
We present a suitable method to describe arbitrarily deformed walls from the spherical shape.
We consider concrete examples and compare our approximations with numerical
solutions. In subsequent papers, we shall consider higher-order finite-width corrections,
and we shall take into account the presence of the fluid.
Study on Laser Selective Curing Additive Manufacturing of Foamed Structural Ceramics

Published: June 2023

Abstract
An additive manufacturing method for ceramic materials with internally formed foaming structure was proposed in this paper with the adoption of ceramic powder and sodium silicate binder to prepare sizing agent. The forming process on each layer consists of three basic processes, including spreading, freezing and laser scanning. Foaming structure arises due to the foaming effect of the frozen sodium silicate caused by laser gasification. After 3D printing, the support material in frozen state will be removed when it has been melt in water. Then finally the green ceramic parts internally filled with foaming structures will come into being. Experimental results show that the laser parameters, the content of ceramic, the scanning spacing and other factors affect the interior appearance of the green part. At the scanning speed of 100 mm·s-1, laser power of 20 W, and 0.3 mm scanning spacing, the ceramic parts are processed with a slurry with 50% solid content. The support materials in the deep fine structure can be quickly removed without mechanical damage or swelling in the water. This new process can be used to process thermal insulation ceramic parts.

Authors: Hu Jie , Chen Hua , Ma Ying , Feng Zhiwei 
Published: June 2023

Abstract
In order to consider the strength of gun barrel more accurately in the design of gun barrel, a virtual prototype of fragment gun barrel is established in this paper. The finite element simulation model of the strength of gun barrel considering the axial force and temperature change is established, and the finite element simulation model of the strength of gun barrel considering the axial force, temperature change and dynamic load is established. Through numerical calculation and finite element simulation, the changes of strength of barrel under axial force, temperature and dynamic loading of bore pressure were analysed. The results show that the maximum stress of the barrel decreases when considering the axial force, and the maximum stress of the barrel increases when considering the temperature change and the dynamic loading of the chamber pressure. The axial force has little effect on the strength of the barrel, and the dynamic load has a significant effect on the strength of the barrel. Through verification, it is found that the designed fragment gun barrel is reasonable and meets the strength requirement.

Published: June 2023

Abstract
For parts with large deep-diameter ratio shaped hole features, the complex structure of the profile and large deep-diameter ratio led to poor profile machining accuracy. The shaped hole processing requires high efficiency, high precision and low cost. Therefore, it is difficult to use the traditional processing method, and the electrolysis method based on the anodic dissolution mechanism is adopted, which has no shear stress and accurate profile forming. The 3D model is established based on the part, and the cathode and tooling structure is designed. Based on COMSOL software, we designed the flow channel uniformity of electrolytic processing of shaped holes and analyzed the arrangement of cathode outlet holes in electrolytic processing, which affects the uniformity of the processed surface and flow field. The arrangement of cathode exits holes to meet the uniform distribution of electrolyte at the surface boundary and high-speed flow at the surface was obtained by simulation analysis. By analyzing the flow field of different inlets, the flow rate magnitude of the shaped boundary and surface of the surface shaped hole is positively correlated with the inlet pressure of the electrode liquid.

Authors: Liu Haitao , Wang Lei 
Published: June 2023

Abstract
The outer space environment is complex, so the research and development of 3D printing equipment depends on the prototype test that is difficult to achieve on the ground, therefore, the performance of the equipment must be investigated by means of simulation. In this paper, the electro-mechanical joint simulation model of the outer space 3D printing equipment is established based on ADAMS and MATLAB/Simulink, which taking into account the overall micro-gravity environment, the nonlinear friction characteristics of each motion-axis, the inertia of each axis, and the overall frame vibration. Based on this model, the point-to-point control and the interpolation motion errors of X and Y axes with external disturbance is realized. At last the comparative control of motion error is realized, which provides a basis for the development of 3D printing equipment in outer space environment.
Thermal Error Modelling for the Parallelism Between the Gear Axis and the Z-axis of GMI
Authors: Ren Yanping , He Dongfeng , Du Hongda 
Published: June 2023

Abstract
Gear measuring instrument (GMI) is the mainstream equipment for gear measurement. As the measurement accuracy of gears improves and GMI is gradually used in production, thermal errors are becoming an important factor affecting the measurement accuracy of GMI. In the precision measurement of the gears, the parallelism errors between the gear axis and the Z-axis of the GMI are the major error source. This error is usually reduced by mechanical adjustment when a GMI is assembled. When the temperature of the GMI and its environment changes, the thermal deformation will lead to new parallelism errors between the gear axis and the Z-axis of the GMI, which will further cause errors in the GMI. In this paper, the effect of the parallelism thermal errors of the GMI is studied, and the parallelism thermal errors model under room temperature environment was established. First, the temperature field of the GMI and its environment and the parallelism thermal errors were measured; then, the TMP are grouped using the FCM, and the key TMP were selected by optimizing the group of the measurement points using Pearson correlation coefficient method; finally, the parallelism thermal errors were established by RBF (Radial Basis Function) neural network and tested by using the measured data. The experimental results show that the predictive accuracy of the established parallelism thermal error model can reach 60.89% in the X direction and 82.26% in the Y direction, indicating good generalization ability and robustness. The model can be used for subsequent thermal error compensation.

Abstract
In this paper, a Super-twisting sliding-mode control method based on a nonlinear interference observer is proposed for the external perturbation of MEMS micromirrors during beam scanning. Developing a physical model of electrostatic MEMS micromirror, the Super-twisting sliding-mode control algorithm based on nonlinear interference observer is applied to the electrostatically driven MEMS scanning micromirror with side electrodes, with the demonstration on stability of the control system by Lyapunov theory.

Abstract
In the oil exploration work, the hammer rod as the main component, due to the insufficient strength of the hammer rod, the hammer head falling off, the hammer body bending deformation and copper layer falling off and other problems often occur in the work, which not only affects the exploration progress but also causes huge economic losses. Aiming at the problem of insufficient strength of the hammer rod, through the analysis of the processing technology of the hammer rod and the working environment of the hammer rod, it is concluded that there are problems in the design of the hammer head, the material selection of the hammer body, and the processing technology of the copper layer. In this regard, the design of the hammer head is optimized, the depth of the inner hole of the hammer head is deepened, and the inner hole of the hammer head is changed to a taper hole; replace the 2CrMo alloy steel with higher strength as the main material of the hammer body, and add a heat treatment process after the rough turning to release the residual stress inside the hammer body; the processing process scheme for replacing the copper layer is attached to the surface of the hammer body by means of a hot-mounted copper sleeve. The improved hammer rod strength fully meets the needs of high-intensity impact work, shortens the exploration time, saves exploration costs, and makes great contributions to the exploration work.
Analysis and Research on Gap Model of Twisted Strand Steel Wire
Authors: Xue Guohua , Zhang Peng , Wang Yajuan 
Published: June 2023

Abstract
The breaking of steel core in the early stage of steel wire rope is a very important factor that restricts the service life of steel wire rope. By analyzing the failure of steel core broken wire, it is found that the key factor affecting the force of twisted strands is the establishment of wire gap model. Based on this, two mathematical models of the elliptic hypothesis and the non-elliptic hypothesis of the steel wire section in twisted strands are established, and two formulas for calculating the steel wire gap are derived. When the steel wire twist Angle is within a certain range, the gap of these two models is very close, but when the twist Angle exceeds a certain value, the difference between the steel wire gap becomes larger and larger. Based on this, the non-elliptic model is used to design different steel core lay lengths, and the experiment verifies that the elastic modulus of the elastic model is close to that of the steel wire rope, which reduces the tensile stress on the steel core when the steel wire rope is used, and improves the phenomenon of steel core breaking.
