Authors: Ababneh Khansa Taha , Farook Fathima Fazrina , Kharashi Tala Al , Arfaj Samar Al , Allahim Renad 
Published: April 2023

Abstract
Objectives General dental practitioners (GDPs) are faced with increasing numbers of patients requesting dental implants (DI) to replace missing teeth. Being the first dental professional consulting with the patient, being knowledgeable about DI contraindications (DIC) would support the development of appropriate treatment plans. This study aimed to investigate the GDPs level of knowledge of a number of DICs. The study was done in Riyadh, KSA.
Materials and Methods A structured electronic questionnaire was distributed to GDPs who consented to participate. Participants were asked whether certain systemic and local conditions were considered DIC, and whether such DIC were considered absolute or relative. Descriptive statistics, t-tests, or one-way analysis of variance, and multiple linear regression were used for the statistical analysis (p ≤ 0.05) to assess the association between the sample characteristics and knowledge of DICs.
Results Less than half (42%) of the respondents scored 25 to 50%, and only 2% scored 75 to 100%. The highest proportion of correct responses was related to questions regarding old age (74.09%), glycemic categories (68.52%), active chemotherapy (64.07%), and intravenous bisphosphonates (49.86%). The responses were significantly associated with the years of experience, place of graduation, and highest qualification in DI. Based on the linear regression analysis, higher years of practice were associated with less knowledge of DIC (inverse relationship), graduates of Saudi governmental universities scored higher than the other groups of graduates, and holders of a master's degree in DI scored higher compared to holders of other qualifications. In addition, respondents who received lectures and/or laboratory training as part of their undergraduate curriculum had higher scores than the group who did not.
Conclusion The level of DIC-related knowledge of the GDPs in Riyadh is generally good but incomplete; it is significantly influenced by the GDPs' years of practice, place of graduation, qualifications, and receiving didactic and laboratory training in the undergraduate programs. More emphasis on DI and DIC is required to improve treatment planning and patient referral.

Authors: Mustafa Lirim , Islami Hilmi , Šutej Ivana 
Published: April 2023

Abstract
Objective Antibiotics are prescribed by dentists during dental treatments, depending on the diagnosis and severity of the disease. Appropriate indicators of the benefit of systematic and regular use of antibiotics in dentistry are limited, because a large number of dental and periodontal problems can be treated either by surgical intervention or by maintaining good oral hygiene. Improper use of antibiotics leads to antimicrobial resistance. In Kosovo, this problem is very evident and more studies are required to identify antibiotic prescribing patterns by health care workers. In this context, this study aims to investigate the issue of antibiotic use in dentistry.
Materials and Methods This prospective study was conducted for 6 months and followed the dental practice of 80 dentists. Data were collected from 795 patient forms.
Results After analysis, results showed that amoxicillin with clavulanic acid and amoxicillin alone were the most commonly prescribed antibiotics, each accounting for 35%. The most common indications for antibiotic prescription were dental and periodontal abscesses (24.9%), while 20.7% of antibiotics were prescribed for postextraction healing, pericoronitis (15%), chronic periodontitis (12.8%), and dry socket (11.5%).
Conclusion These results suggest that the problem of inappropriate antibiotic prescribing is not only overprescribing but also the selection of inappropriate agents, especially amoxicillin with clavulanic acid, instead of amoxicillin alone.
Replication Timing Aberration of KIF14 and MDM4/PI3KC2β Alleles and Aneuploidy as Markers of Chromosomal Instability and Poor Treatment Response in Ewing Family Tumor Patients
Authors: Ayala Fernanda Rocha Rojas , Martin Jeffrey William , Bertuzzo Carmen Silvia 
Published: April 2023

AbstractReplication timing of allelic gene pairs is strictly regulated according to expression, genome stability, and epigenetic changes, and tumorigenesis may be associated with changes in the allelic replication in various tumors. Our aim was to determine whether such alterations had a prognostic value in Ewing's family tumor (EFT) patients. The KIF14 and MDM4/PI3KC2β and the centromeric satellite sequence of chromosomes 8 and 12 were used for replication timing assessments. Aneuploidy was assessed by enumerating the copy numbers of chromosomes 8 and 12. Replication timing and aneuploidy were detected cytogenetically using multicolors fluorescence in situ hybridization assay applied in 135 EFT. Patients with trisomy 8 presented an association with an asynchronous replication pattern (SD) of MDM4/PI3KC2β genes (p = 0.013). Trisomy 12 was associated with a synchronous pattern (DD) of KIF14 probe signals (p = 0.04). The DD synchronous replication pattern of KIF14 showed a correlation with age (p < 0.0001), and the SS synchronous replication pattern of the same locus showed a correlation with lung metastatic (p = 0.012). The subgroup of patients presenting with multiplet signals of MDM4/PI3KC2β showed an association with treatment response (p = 0.045) and age (p = 0.033). Replication pattern of KIF14 may, significantly, be associated with chromosomal instability as MDM4/PI3KC2β may be a considerably new marker of poor treatment response in EFT patients.

Published: April 2023

AbstractSkin closure for total knee arthroplasty (TKA) typically focuses on promoting optimal healing, while preventing wound complications and infection, allowing for functionality and immediate ambulation, and providing for excellent cosmesis. In this systematic review and meta-analysis of the literature, we will focus on closure of the skin. Specifically, we assessed: (1) wound complication risk of different techniques and (2) closing time of different sutures/techniques. There were 20 reports on infection risk and closing time. Meta-analyses focused on the qualifying studies for closing time and wound complication risk reports were also performed. These studies (378 patients) demonstrated overall lower wound complication risks with the use of barbed compared with traditional sutures (3% vs. 6%, p < 0.05). The subsequent meta-analysis included 749 patients demonstrating overall significant closing time reductions of a mean of 7 minutes with the use of barbed sutures (p < 0.05). Therefore, multiple recent reports suggest superior outcomes and faster results when using barbed sutures for TKA skin closure.
Social appropriateness in HMI

Published: April 2023

AbstractSocial appropriateness is an important topic – both in the human-human interaction (HHI), and in the human-machine interaction (HMI) context. As sociosensitive and socioactive assistance systems advance, the question arises whether a machine’s behavior should include considerations regarding social appropriateness. However, the concept of social appropriateness is difficult to define, as it is determined by multiple aspects. Thus, to date, a unified perspective, encompassing and combining multidisciplinary findings, is missing. When translating results from HHI to HMI, it remains unclear whether such insights into the dynamics of social appropriateness between humans may in fact apply to sociosensitive and socioactive assistance systems. To shed light on this matter, we propose the Five Factor Model of Social Appropriateness (FASA) which provides a multidisciplinary perspective on the notion of social appropriateness and its implementation into technical systems. Finally, we offer reflections on the applicability and ethics of the FASA Model, highlighting both strengths and limitations of the framework.
An epistemic logic for formalizing group dynamics of agents
Authors: Costantini Stefania , Formisano Andrea , Pitoni Valentina 
Published: April 2023

Abstract
In the multi-agent setting, it is relevant to model group dynamics of agents, and logic has proved a good tool to do so. We propose an epistemic logic, L-DINF-E, that allows one to formalize what are the beliefs formed by a group of agents, where several groups exist and agents can pass from a group to another one. We introduce a new modality which allows an agent to reason about the beliefs of other agents. This allows us to model aspects of the “Theory of Mind”, understood as the set of social-cognitive skills involving the ability to attribute and reason about mental states, desires, beliefs, and knowledge of agents. In this paper, we present the logic L-DINF-E and illustrate how it can be used to solve “false-belief tasks”, i.e., tests in which an agent should understand that some other agent may develop, under some circumstances, false beliefs.
Toward understanding the effects of socially aware robot behavior
Authors: Roesler Oliver , Bagheri Elahe , Aly Amir 
Published: April 2023

Abstract
A key factor for the acceptance of robots as regular partners in human-centered environments is the appropriateness and predictability of their behaviors, which depend partially on the robot behavior’s conformity to social norms. Previous experimental studies have shown that robots that follow social norms and the corresponding interactions are perceived more positively by humans than robots or interactions that do not adhere to social norms. However, the conducted studies only focused on the effects of social norm compliance in specific scenarios. Therefore, this paper aims to guide further research studies by compiling how researchers in relevant research fields think the perception of robots and the corresponding interactions are influenced independently of a specific scenario if a robot’s behavior conforms to social norms. Additionally, this study investigates what characteristics and metrics constitute a good general benchmark to objectively evaluate the behavior of social robots regarding its conformity to social norms according to researchers in relevant research communities. Finally, the paper summarizes how the obtained results can guide future research toward socially aware robot behavior.
Stacking and layer dependence of magnetic properties in Ti2C and Fe2C

Published: April 2023

Abstract
Magnetic MXenes are becoming an important family of materials for exploring 2D magnetism. However, investigations into the interdependence of layer thickness, stacking patterns and magnetism in these materials, from a microscopic point of view, are still lacking. In this work, we have used density functional theory based calculations to understand the effects of layer thickness and stacking on the magnetic properties in two magnetic MXenes, Ti2C and Fe2C, in their monolayer and bilayer forms. The ground-state magnetic structures, magnetic moments, magnetic exchange interactions, magnetic transition temperatures and magnetic anisotropy energies are calculated and analysed using their electronic structures and standardised models. We find that in both systems an increase in layer thickness (monolayer to bilayer) affects the ground-state magnetic configuration, which is driven by the changes in the magnetic exchange interactions. While the effects of the stacking pattern are rather weak in Ti2C, they are substantial, both qualitatively and quantitatively, in Fe2C. The computed results are analysed from their electronic structures. The results suggest that fascinating physical effects can be obtained in Fe2C by tuning the layer thickness and stacking patterns, making it more suitable for device applications.

Published: April 2023

Abstract
Very often the magnetic skyrmions (topologically protected spin textures) form a triangular crystal in chiral magnets. Here we study the effect of itinerant electrons on the structure of skyrmion crystal (SkX) on triangular lattice using Kondo lattice model in the large coupling limit and treating the localized spins as classical vectors. To simulate the system, we employ hybrid Markov Chain Monte Carlo method (hMCMC) which includes electron diagonalization in each MCMC update for classical spins. We present the low-temperature results for

Role of symmetry in quantum blocking of Andreev reflection in graphene nanoribbons side-terminated by superconductors
Authors: Takagaki Y 
Published: April 2023

Abstract
Andreev reflection can be forbidden by means of quantum interference when superconductors are attached at the side edges of graphene nanoribbons (GNRs). The blocking is restricted to single-mode nanoribbons having symmetric zigzag edges and is destroyed by the application of a magnetic field. These characteristics are shown to be the effects of the wavefunction parity on the Andreev retro and specular reflections. Not only the mirror symmetry of the GNRs but also symmetric coupling of the superconductors is required for the quantum blocking. The quasi-flat-band states around the Dirac point energy induced for armchair nanoribbons by adding carbon atoms at the nanoribbon edges do not cause the quantum blocking due to the lack of the mirror symmetry. Furthermore, the phase modulation by the superconductors is shown to be able to convert the quasi-flat dispersion for the edge states of zigzag nanoribbons to a quasi-vertical dispersion.

Published: April 2023

Abstract
A novel type of superconducting joining technique has been introduced to join unreacted internal Mg diffusion (IMD) single-core MgB2 wires. Our method is based on fabricating a small diameter joint mould obtained by deforming an Nb/Cu composite tube with a longitudinal semi-cylindrical Mg and B core into a thick round wire. The small diameter of the joint provided advantages such as rapid cooling, low resistance, and the unique core design inside the joint ensured a uniform MgB2 phase formation. Scanning electron microscope analysis revealed that the IMD MgB2 wires had excellent contact with the superconducting MgB2 bulk material inside the joint. The joint resistance, calculated from the decay of the trapped magnetic field over time, is a quite low value of 6.44 × 10−16 Ω at 20 K. The transport critical current (I
c) of the joint is 62 A at 20 K under a self-magnetic field, and the n-value of the joint is 66 at 20 K under 1.5 T. The results showed that the I
c of our joint can be determined precisely, regardless of whether the magnetic field is applied from low to high or from high to low value during I–V measurements.

Abstract
We used the asymmetric superconducting quantum interference device (SQUID) technique to extract the current phase relation (CPR) of a Josephson junction with a 3D-topological insulator (3D-TI) Bi2Se3 nanobelt as the barrier. The obtained CPR shows deviations from the standard sinusoidal CPR with a pronounced forward skewness. At temperatures below 200 mK, the junction skewness values are above the zero temperature limit for short diffusive junctions. Fitting of the extracted CPR shows that most of the supercurrent is carried by ballistic topological surface states (TSSs), with a small contribution of diffusive channels primarily due to the bulk. These findings are instrumental in engineering devices that can fully exploit the properties of the topologically protected surface states of 3D TIs.
Study of the optical force on nano-structured surfaces
Authors: Yuan Yukun , Gu Chunyang , Huang Siyu , Chen Shufan , Li Zexiao , Fang Fengzhou 
Published: April 2023

Abstract
The optical force is a miniscule force originating from light–matter interactions and ranging from a few nano-Newtons to micro-Newtons. This study demonstrates that this force can be enhanced or changed using structured surfaces. The mechanism is studied through a resonant-excited electromagnetic field on a periodic nano-structured surface. The quantitative relationship between the periodic structure and the resultant force is determined using finite element analysis, and the experimental results are in good agreement with the theoretical analysis. Compared to planar reflectors, the optical force can be greatly amplified on periodic cavity structures, depending on the cavity parameters. The findings of this study can serve a wide range of applications, such as opto-mechanical systems and sensitive detection of laser power.
Invisible neutrino decays as origin of TeV gamma rays from GRB221009A
Authors: Huang Jihong , Wang Yilin , Yu Bingrong , Zhou Shun 
Published: April 2023

Abstract
Recently, the LHAASO collaboration has observed the gamma rays of energies up to ten TeV from the gamma-ray burst GRB221009A, which has stimulated the community of astronomy, particle physics and astrophysics to propose various possible interpretations. In this paper, we put forward a viable scenario that neutrinos are produced together with TeV photons in the gamma-ray burst and gradually decay into the axion-like particles, which are then converted into gamma rays in the galactic magnetic fields. In such a scenario, the tension between previous axion-like particle interpretations and the existing observational constraints on the relevant coupling constant and mass can be relaxed.

Abstract
We present the cost-effective production of superconducting
radio frequency (SRF) cavities made of medium grain (MG) niobium
(Nb) discs directly sliced from forged and annealed billet. This
production method provides clean surface conditions and reliable
mechanical characteristics with sub-millimeter average grain size
resulting in stable SRF cavity production. We propose to apply this
material to particle accelerator in the science and industrial
applications. The science applications require high field
gradients(≥ 30 MV/m) particularly in pulsed mode. The
industrial applications require high Q
0 values with moderate
gradients (∼ 20 MV/m) in CW mode operation. This paper
describes the MG Nb disc production recently demonstrated and
discusses future prospects for application in advanced particle
accelerators in the science and industrial applications.
Review of linear and nonlinear models in breath analysis by Cyranose 320

Published: April 2023

Abstract
Analysis of volatile organic compounds (VOCs) in breath specimens has potential for point of care (POC) screening due to ease of sample collection. While the electronic nose (e-nose) is a standard VOC measure across a wide range of industries, it has not been adopted for POC screening in healthcare. One limitation of the e-nose is the absence of mathematical models of data analysis that yield easily interpreted findings at POC. The purposes of this review were to (1) examine the sensitivity/specificity results from studies that analyzed breath smellprints using the Cyranose 320, a widely used commercial e-nose, and (2) determine whether linear or nonlinear mathematical models are superior for analyzing Cyranose 320 breath smellprints. This systematic review was conducted according to the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analyses using keywords related to e-nose and breath. Twenty-two articles met the eligibility criteria. Two studies used a linear model while the rest used nonlinear models. The two studies that used a linear model had a smaller range for mean of sensitivity and higher mean (71.0%–96.0%; M = 83.5%) compared to the studies that used nonlinear models (46.9%–100%; M = 77.0%). Additionally, studies that used linear models had a smaller range for mean of specificity and higher mean (83.0%–91.5%; M = 87.2%) compared to studies that used nonlinear models (56.9%–94.0%; M = 76.9%). Linear models achieved smaller ranges for means of sensitivity and specificity compared to nonlinear models supporting additional investigations of their use for POC testing. Because our findings were derived from studies of heterogenous medical conditions, it is not known if they generalize to specific diagnoses.
Challenges and recent progress in carbon-based nanocomposites for sportswear and sensing applications
Authors: Yang Leiming 
Published: April 2023

Abstract
Sportswear is an essential auxiliary wear for physical education activities in colleges and universities. Unfortunately, most sports equipment is made of heavyweight, expensive, and easily rusted metals. Herein, we report the recent progress in carbon-based nanocomposites for sportswear and sensors. To extend the service life of sportswear, advanced lightweight materials for sports goods are briefly discussed. Carbon materials such as 0D fullerenes, 1D carbon nanotubes, 2D graphene, and 3D graphite and their nanocomposites are more and more widely used in various industries in the world, and sportswear has no exceptions. Their superior performance and huge potential have a certain impact on improving sports performance. Firstly, we overviewed the advantages and multifunctional carbon nanocomposites in sportswear, and wearable sports applications at the present stage are explored. While simultaneously monitoring health or energy storage applications also explored, indeed the integration of all desirable functions into lightweight wearable sports goods emerged as a significant breakthrough for effective sports activities. More importantly, some sportswear prototypes equipped with unprecedented characteristics have also been overviewed in this review. Despite the recent developments, many barriers and difficulties still remain. New prospects are also suggested. This article seeks to inspire sports research communities to drive onward real-time advancement in the sports industry.
