Dark matter condensates as highly nonlocal solitons: instability in the Schwarzschild metric and laboratory analog
Authors: Dieli Ludovica , Conti Claudio 
Published: February 2024

Abstract
Theories on the bosonic nature of dark matter are a promising alternative to the cold dark matter model. Here we consider a dark matter halo in the state of a Bose–Einstein condensate (BEC), subject to the gravitation of a black hole. In the low energy limit, we bring together the general relativity in the Schwarzschild metric and the quantum description of the BEC. The model is solvable in the Fermi normal coordinates with the so called highly nonlocal approximation and describes tidal deformations in the condensate wave function. The black hole deforms the localized condensate until the attraction of the compact object overcomes the self-gravitation and destabilizes the solitonic dark matter. Moreover, the model can be implemented as a gravitational analog in the laboratory; the time-dependent potential generated by the galactic black hole can be mimicked by an optical trap acting on a conventional condensate. The results open the way to new laboratory simulators for quantum gravitational effects.

Abstract
In this work, we present the synthesis of multi-phase MoO3–MoSx (Mo–O–S) nanostructure as an outstanding photocatalyst through the straightforward hydrothermal method. The as-synthesized Mo–O–S nanostructure exhibited high purity and well-defined crystallite phases, featuring rods with average diameters ranging from 100–200 nm and thick flakes of 10–25 nm. The optical characterization of the as-prepared Mo–O–S nanostructure reveals four distinct emission peaks within the 520–680 nm wavelength range. The photocatalytic activity of the Mo–O–S nanostructure was evaluated through the degradation of rhodamine B (RhB), methylene blue (MB), and crystal violet (CV) dyes. The results unveil impressive degradation efficiencies, achieving 65%, 82%, and 89% after 180 min of exposure to UV irradiation for RhB, MB, and CV dyes, respectively. This pioneer investigation underscores the potential of the MoO3–MoSx nanostructure as a promising catalyst for the effective degradation of multiple dyes.
Robust transport and topological valley refraction of fundamental symmetric lamb waves in perforated phononic crystal plates
Authors: Li Hong-kang , Huo Shao-yong , Yang Qiu-shuang , Qu Wei , Fu Chun-ming 
Published: February 2024

Abstract
Lamb waves can be divided into antisymmetric Lamb waves (type A) and symmetric Lamb waves (type S), which are widely used in health monitoring of engineering structures and nondestructive evaluation of materials. However, due to the fact that each mode of Lamb wave has the setting group velocity in a certain bandwidth range, it is easy to cause the aliasing of multi-mode Lamb waves, partly limiting the application scenarios of Lamb wave. In this paper, a hexagonal lattice meta-structure is designed and the zero-order symmetric (S0) Lamb wave in a finite thickness plate is successfully separated. By breaking the spatial C
3v
symmetry, a valley topological phononic crystal (PnC) plate for the pure S0 mode is constructed, and its robust topological transports are demonstrated. Firstly, the valley topological phase transition of S0 mode is realized by changing the angle of scatterer in PnC plate and the valley edge state of S0 mode is obtained. Furthermore, by introducing structural mismatch, it is verified that the edge state of S0 mode is robust to various bends and defect. Finally, by changing the material property of the terminal, the valley refraction with different directionality is realized. The results offer a route to individually study the symmetric modes of Lamb waves, and have potential application prospects in rapid and accurate ultrasonic nondestructive testing based on Lamb waves.
Inflation in symmergent metric-Palatini gravity
Authors: Bostan Nilay , Karahan Canan , Sargın Ozan 
Published: February 2024

Abstract
In this paper, we study the cosmological inflation phenomenon in symmergent gravity theory. Symmergent gravity is a novel framework which merges gravity and the standard model (SM) so that the gravity emerges from the matter loops and restores the broken gauge symmetries along the way. Symmergent gravity is capable of inducing the gravitational constant G and the quadratic curvature coefficient cO
from the loop corrections of the matter sector in a flat space-time. In the event that all the matter fields, including the beyond the standard model (BSM) sector, are mass degenerate, the vacuum energy can be expressed in terms of G and cO
. The parameter which measures the deviation from the mass degeneracy is dubbed α̂. The parameters, cO
and α̂, of symmergent gravity convey the information about the fermion and boson balance in the matter (SM+BSM) sector in number and in mass, respectively. In our analysis, we have investigated the space of the symmergent parameters cO
and α̂ wherein they produce results that comply with the inflationary observables ns
, r, and dns
/d ln k.
We have shown that the vacuum energy together with the quadratic curvature term arising in the symmergent gravity prescription are capable of inflating the universe provided that the quadratic curvature coefficient cO
is negative (which corresponds to fermion dominance in number in the matter sector) and the deviation from the mass degeneracy in the matter sector is minute for both boson mass dominance and fermion mass dominance cases.
Deviations’ analysis of the single-family buildings in the mining area
Authors: Orwat J 
Published: February 2024

Abstract
In this work changes of the inclinations values (in a horizontal plane) of a land surface and two buildings have been shown. They were induced by an operation of the 404 and the 405 coal beds located successively on the level of 490 m and 550 m, and realized on a south of the buildings (the South of Poland) by the use of five longwalls. Values of inclinations from the results of the geodesic measurements done in August 2019 have been determined. Subsidence and distances between neighbouring points (on a land surface and on the buildings’ walls) have been observed. Observations in two perpendicular directions, on 24 points (12 ground points and 12 wall points) have been conducted. Research results indicate that deviations are different for a ground and the buildings. It means that a process of deformation of the buildings and a terrain surface takes place differently. Moreover, the ground steps which occurred near the buildings (one in front of the first building, the other under the second building) cause anomalies in the inclinations values and changes in their directions and turns.

Published: February 2024

Abstract
The article deals with the design of a device working on the principle of Fused Deposition Modeling - FDM and its peripherals. Among the most important performing activities of the designer is the analysis of the proposed model with regard to the strength and the resulting accuracy of the created three-dimensional object. The input requirements that the proposed device should meet were defined. Based on these criteria, a numerical and strength analysis was developed using the FEM finite element method. The simulation was carried out on the basis of the hypothesis of shear stress transformation work, which is among the most accurate for the tough materials used. The analysis monitored and evaluated the deformations in the extreme positions where the largest deformations were expected to occur.

Abstract
Current engineering production is characterised by rapid changes. These changes arise due to the shortening of product life cycles. Manufacturers are forced to introduce upgraded products at shorter intervals based on customer requirements. In this paper, we focus on the possibilities of production upgrading by using a group technology in the flexible manufacturing system. The production capabilities of one of the production machines in the manufacturing system will be analysed. This production machine is a lathe that produces one of the essential parts of a finished product. Determine what variations of this part can be produced without changing the physical configuration of the machine.
The Importance of Application of EN ISO 3834 and EN 1090 in Production of Steel Structures
Authors: Bajramovic E , Bajramovic E , Bajramovic E , Islamovic Fadil 
Published: February 2024

Abstract
Fractures of welded structures in operational conditions most often occur in the welded joint or its immediate vicinity. Due to this, special attention is paid to ensuring the quality of the welded joint. The application of the EN ISO 3834 and EN 1090 standards in the manufacture of steel structures aims to ensure the highest possible quality of welded joints, and thus the quality of the structures as a whole. Weld quality is achieved by welding, whereas weld quality control provides a check of product reliability. Increasing requirements in terms of reliability, better use of materials, lower weight and cost of constructions, but also high use of load-bearing structural elements, and thus welded joints, leave less room for errors in welded joints, which is why constant control and monitoring of documented procedures is required.
Numerical simulation of the welding process for the prediction of temperature distribution on Al/steel explosion welded joint
Authors: Maćkowiak P , Płaczek D 
Published: February 2024

Abstract
Joining steel and aluminum alloys is a common problem in many engineering structures. One of the alternatives for combining these materials is welding them using explosively welded transition joints. The biggest problem is the difference in welding temperatures of steel and aluminum alloys. The higher welding temperature of steel means there is a high risk of overheating the aluminum alloy in the transition joint. One of the methods of optimizing the dimensions of an explosively welded connector is to conduct experimental tests. These tests can indicate the minimum size of the connector in which the steel welding process does not cause changes in the microstructure and strength of the aluminum alloy. Conducting experimental research is time-consuming and expensive. First, it is necessary to produce explosively welded plates. Secondly, specimens of welded joints must be prepared. In order to minimize costs and speed up the design process, the number of experimental tests can be reduced by conducting numerical analyses. The aim of this work is to describe a method for modeling the distribution of temperature fields during welding of steel and aluminum alloy joints using transition joints. The method of manufacturing joint specimens and the method of experimental measurement of temperature during welding are described. The results compare the temperature distributions in an explosively welded connector during steel welding, determined experimentally and using numerical methods.

Published: February 2024

Abstract
Due to the continuous development of the automotive and machine building industry, there has been an urgent need to develop steels with increasingly high strength, without compromising toughness and ductility characteristics. On the other hand, it is necessary for these steels to show high strength even at high temperatures. In this context, there is great interest in high-strength steels, with numerous studies and research in this field of research.
The numerical values of the mechanical characteristics of a steel are determined through a series of tests differentiated by the type of macroscopic deformation generated, the method of applying the load, the testing temperature, etc. The most common tests used are static tensile tests and dynamic impact bending tests.
This paper presents an optimization of mechanical characteristics based on the chemical composition of the steel, various heat treatment options, and testing conditions.

Thinking What We Are Doing
Authors: Sheen Erica 
Published: February 2024

Abstract
W. H. Auden’s lectures on Shakespeare at the New School for Social Research in Greenwich Village, New York, in 1946–7 provide the context for a recapitulation of the geopolitical dynamics that have been the subject of the preceding chapters. This chapter examines Auden’s friendship with Hannah Arendt as it developed in discussions of Auden’s Shakespearian understanding of the concepts of forgiveness and pardon, but it asks if the attempt to use Shakespeare to find answers to the problem of how to live is sufficient to the task of confronting, in Arendt’s famous phrase, ‘the banality of evil’. Tracking the origins of the phrase to an earlier dialogue between Arendt and Karl Jaspers, it concludes that we can at best identify Shakespeare’s place in her signature concept of ‘thinking what we are doing’ with the radical indecision of her controversial account of Eichmann in Jerusalem.
Beyond Transplant: A Network Innovation Model of Transnational Regulatory Change
Authors: Harper Ho Virginia 
Published: February 2024

Abstract
Seeking inspiration from different legal systems in order to solve common policy problems is a core enterprise of comparative law. However, dominant understandings in comparative law and regulatory theory about how norms, rules, and formal institutions move across borders are increasingly inadequate in the face of modern transnational policy challenges. Solving transnational problems requires regulatory innovation, complex coordination, and even competition among private and public actors in multiple jurisdictions, as well as much faster policy responses than most countries can achieve either domestically or multilaterally. Accelerating solutions to emerging transnational problems therefore demands a new focus within comparative law on how transnational legal innovation works and how to leverage its benefits faster on both a global and local scale.
This Article proposes a conceptual framework to ground this effort—a “network innovation” model of transnational law formation. Building on earlier literatures on legal transplant, policy diffusion, institutional change, and transnational legal ordering, as well as studies of firm-level innovation, this approach recognizes that new norms, rules, and other institutions are sourced from, coordinated by, and transmitted through transnational networks of public and private actors. Moving beyond prior literatures, however, it views transnational law formation as an aggregating process of innovation where the resulting outputs are the complex product of multiple experimental sites and sources. This approach offers a more accurate descriptive account of transnational regulatory change and points to network innovation processes as central to solving common or collective transnational problems. This Article illustrates the proposed framework with case studies of efforts to build sustainable financial systems. It concludes by suggesting strategies to accelerate network innovation and considering how this theoretical paradigm might inform new directions in comparative law.

Abstract

Objectives
The high incidence of prostate cancer causes prostatic samples to significantly affect pathology laboratories workflow and turnaround times (TATs). Whole-slide imaging (WSI) and artificial intelligence (AI) have both gained approval for primary diagnosis in prostate pathology, providing physicians with novel tools for their daily routine.

Methods
A systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was carried out in electronic databases to gather the available evidence on the application of AI-based algorithms to prostate cancer.

Results
Of 6290 articles, 80 were included, mostly (59%) dealing with biopsy specimens. Glass slides were digitized to WSI in most studies (89%), roughly two-thirds of which (66%) exploited convolutional neural networks for computational analysis. The algorithms achieved good to excellent results about cancer detection and grading, along with significantly reduced TATs. Furthermore, several studies showed a relevant correlation between AI-identified histologic features and prognostic predictive variables such as biochemical recurrence, extraprostatic extension, perineural invasion, and disease-free survival.

Conclusions
The published evidence suggests that AI can be reliably used for prostate cancer detection and grading, assisting pathologists in the time-consuming screening of slides. Further technologic improvement would help widening AI’s adoption in prostate pathology, as well as expanding its prognostic predictive potential.

Incorporation of deuterated coronene into cage-like sodalite-type porous organic salts and improvement of room-temperature phosphorescence properties
Authors: Sei Hiroi , Oka Kouki , Furuta Tomoki , Tohnai Norimitsu 
Published: February 2024

Abstract
Host materials with external heavy atom effects do not change the chemical structures of incorporated luminescent molecules but promote intersystem crossing from the excited singlet state to the excited triplet state, which induces room-temperature phosphorescence (RTP). The deuteration of luminescent molecules suppresses non-radiative deactivation via C–H stretching vibration; therefore, the improvement of both phosphorescence lifetime and quantum efficiency (i.e. isotope effect) is expected. Although a combination of the external heavy atom effect and isotope effect could be expected to improve phosphorescent performances dramatically, an environment with a strong external heavy atom effect (density of iodine atoms ≥0.65 gcm−3) increases non-radiative deactivation via spin-orbit coupling; therefore, the isotope effect is hindered, and the phosphorescent lifetime and quantum efficiency are not usually improved. In the current work, we constructed cage-like sodalite-type porous organic salts (s-POSs) where the density of iodine atoms (0.55 gcm−3) was moderate (0.13 ̶ 0.65 gcm−3). Incorporation of a deuterated representative luminescent molecule such as coronene (coronene-d12) into s-POSs enabled the exerting of both the external heavy atom effect and isotope effect, which successfully improved both RTP lifetime (1.1 times) and quantum efficiency (1.6 times) over those of an incorporated ordinary coronene (coronene-h12).

Published: February 2024

Abstract
Pre-lithiation technology is essential for lithium-ion capacitors to have high voltage and cycle stability. In this work, we propose an in situ chemical pre-lithiation method, which can accurately control the depth of pre-lithiation in the graphite anode. After 1,000 charge/discharge cycles at a high temperature of 65 °C, the lithium-ion capacitor still has 85% discharge capacity. The anode using this pre-lithiation method was found to have a stable potential after cycling.

Published: February 2024

Abstract
Youth with mental health needs face barriers in seeking and accessing help, especially in resource-constrained settings in Majority World Countries. Community engagement is thus important for mental health promotion, particularly in addressing stigma. Engagement can be enhanced by involving peer educators and by relating to intergenerational experiences in the sociocultural context of the community. The aim of this study was to explore how intergenerational experiences and perspectives can inform the co-production of youth-led mental health promotion in a Majority World Country, Pakistan. We recruited 11 families (one grandmother, mother and granddaughter in each family) as advisers from two disadvantaged areas of Karachi, and 14 peer educators. Training for peer educators included seminars, experiential activities, three participatory workshops with family advisers and supervision. A sub-sample of family advisers and peer educators attended four focus groups, and peer educators completed reflective diaries following each activity. Data were integrated and subjected to thematic codebook analysis. The three themes related to enabling and hindering factors towards co-production of mental health promotion, incorporation of intergenerational resilience and cascading knowledge to communities. The findings highlighted potential benefits of youth-led mental health promotion that contextualizes intergenerational experiences for those communities. Peer educator roles should be supported by training, and mental health promotion should be integrated within local service systems.
