Authors: Wu TianYou , Farella Mauro , Guan Simon , Cannon Richard D. , Mei Li 
Published: February 2025

Abstract

Objectives
To investigate the debonding protocols used by orthodontists in New Zealand.

Materials and methods
A pilot-tested electronic questionnaire was distributed to all full members of the New Zealand Association of Orthodontists (NZAO). The survey consisted of 12 questions which collected demographic information and details of the debonding protocols practiced by the orthodontists.

Results
The response rate to the survey was 56.6% (n=60 respondents). Most NZ orthodontists (80.0%, n=48) preferred the use of debonding pliers to remove orthodontic brackets. A total of 23 different methods were identified for the subsequent removal of residual adhesive of which a low-speed tungsten carbide bur was the most popular tool (83.3%, n=50). The majority of the NZ orthodontists (96.7%, n=58) performed polishing after the removal of residual adhesive. About 80% (n=47) of the NZ orthodontists reported iatrogenic damage to the enamel following debonding. Almost all NZ orthodontists (98.3%, n=59) were satisfied with their debonding protocol.

Conclusion
Orthodontists in New Zealand use different debonding protocols, of which the most common was the use of debonding pliers combined with a low-speed tungsten carbide bur without irrigation, followed by additional polishing using pumice and a rubber cup. The commonly-used debonding protocol may not necessarily be the most appropriate approach based on current best evidence. Orthodontists should maintain a critical stance and consistently re-assess the literature to evaluate the appropriateness of their debonding protocol.

On the explicit geometry of a certain blowing-up of a smooth quadric
Authors: De La Rosa-Navarro B. L. , Failla G. , Frías-Medina J. B. , Lahyane M. , Utano R. 
Published: February 2025

Abstract
Using the high symmetry in the geometry of a smooth projective quadric, we construct effectively new families of smooth projective rational surfaces whose nef divisors are regular, and whose effective monoids are finitely generated by smooth projective rational curves of negative self-intersection. Furthermore, the Cox rings of these surfaces are finitely generated, the dimensions of their anticanonical complete linear systems are zero, and their nonzero nef divisors intersect positively the anticanonical ones. And in two special cases, we give efficient ways of describing any effective divisor class in terms of the given minimal generating sets for the effective monoids of these surfaces. The ground field of our varieties is algebraically closed of arbitrary characteristic.

Published: February 2025

Abstract
In this paper, we focused on biharmonic, f-harmonic and f-biharmonic magnetic curves in trans-Sasakian manifolds. Moreover, we obtain necessary and su cient conditions for magnetic curves as well as Legendre magnetic curves to be biharmonic, f-harmonic and f-biharmonic. We investigate the states of these conditions in α-Sasakian, β-Kenmotsu and cosymplectic manifolds. Besides, we obtain some nonexistence theorems.

Authors: Büyükkaya Abdurrahman , Öztürk Mahpeyker 
Published: February 2025

Abstract
In this paper, inspired by Proinov type contractions, we intend to acquire novel definitions and results that expand Sehgals [3] metric fixed point theory in the sense of modular b−metric space. To demonstrate the theorems, we employ a general form of (α, β) −admissible and multi-valued mappings and obtain some general results for single-valued mapping in the context of modular b−metric space.
On the dual quaternion geometry of screw motions
Authors: Erişir Tülay , Mumcu Gökhan , Kızıltuğ Sezai , Yaylı Yusuf 
Published: February 2025

Abstract
In this study, the screw motions are studied using dual quaternions with the help of di erent perspectives. Firstly, orthogonality definition of dual quaternions is given and geometric interpretation of orthogonality condition is made. Then, the definition of dual circle is given using orthogonal dual quaternions and it is proved that this dual circle can represent the set of all screw motions. Also, these given theorems are reinforced with some conclusions. In addition, it is seen that a dual quaternion represents a screw motions as a screw operator therefore, other dual quaternions derived from the same dual quaternion represent the same screw motions. Then, it is seen that a screw motions symbolized by a dual quaternion transforms one dual vector to another, and when the sign of the dual vectors changes, it provides the same screw motions. Consequently, the answer of the question “Which dual circles symbolizing screw motions are dual orthonormal to each other?” is given and an important conclusion is obtained regarding this.
A New Filled Function for Global Optimization
Authors: Şahiner Ahmet , Ermiş Temel , Awan Muhammad Wasim 
Published: February 2025

Abstract
The filled function method has recently become very popular in optimization theory, as it is an e cient and e ective method for finding the global minimizer of multimodal functions. However, the fact that the existing filled functions in the literature generally have exponential or logarithmic terms and/or parameter sensitivity reduces the e ectiveness of this method. In this study, we propose a new non parameter and without exponential/logarithmic terms filled function, which is numerically stable, and is successfully used to solve global optimization problems. Furthermore, we have demonstrated how successful this new filled function method in terms of e ciency with numerical experiments and comparisons.

Authors: Unal Arzu , Demirci Elif 
Published: February 2025

Abstract
In this paper, the unknown parameters of a SEIRS mathematical model for the dynamics of COVID-19 are estimated by the least squares approach using data of Trkiye. In the considered model, the infective group is divided into two classes consisting of diagnosed and undiagnosed individuals. Since the data for undiagnosed infective individuals in the community is unknown, three di erent scenarios are proposed. The numerical solutions of the model using the estimated parameter values and the actual data are demonstrated with graphs.

The study of the linear methods of approximation, which are given by sequences of positive and linear operators, studied extremely, in relation to different subjects of analysis, such as numerical analysis. The principal objective of this manuscript is to develop a new and more comprehensive version of Gamma type operators and presented their approximation features. For this purpose, we benefit from two sequences of functions, which are α

To indicate how the function τ play a significant role in the construction of the operator, we reconstruct the mentioned operators which preserve exactly two test functions from the set {1, τ, τ2}. Then we established Voronovskaya type theorem and order of approximation properties of the newly defined operators utilizing weighted modulus of continuity to show that their approximation properties. At the end of this note, we present a series of numerical results to show that the new operators are an approximation technique.
A new approach to (dual) Rickart modules via isomorphisms
Authors: Asgari S. , Talebi Y. , Moniri Hamzekolaee A. R. 
Published: February 2025

Abstract
In the past few decades, researchers have found that studying modules using endomorphisms is a powerful and useful tool. This has led to valuable works in this field. Recently, the study of (dual) Rickart modules has become an important approach as they are deeply connected to endomorphisms. Building on this work, the authors introduce a new perspective on (dual) Rickart modules using isomorphism. We also define virtually (dual) Rickart modules. It is shown that rings with all modules virtually Rickart are semisimple rings. The paper includes various examples to illustrate the concepts presented.

Authors: Jocković Jelena , Todić Bojana 
Published: February 2025

Abstract
We consider a generalization of the coupon collector problem with unequal probabilities, such that there are two additional coupons in the coupon set: one that speeds up the coupon collection process, and the one that slows it down. We derive some upper and lower bounds on the distribution function of the waiting time until a subcollection or a full collection of coupons is sampled.

Authors: Polat Ahmet , Horzum Mehmet Barış 
Published: February 2025

Abstract
The COVID-19 pandemic necessitated a sudden transition to Emergency Remote Teaching (ERT) in Turkey, as well as around the world, presenting unprecedented challenges for teachers. This study investigates the experiences of K-12 teachers during this period, focussing on the challenges they faced, the strategies they employed to address them and their perspectives on the advantages and disadvantages of ERT. Data were collected from 385 teachers through a qualitative survey conducted at the end of the 2019–2020 academic year. Content analysis revealed key findings that clustered around ‘Technology’ (access, system, competence) and ‘Pedagogy’ (interaction, motivation, classroom management). Teachers have developed various strategies to address these challenges. This research offers valuable insights into the challenges and opportunities of ERT and provides practical recommendations to enhance the quality and equity of online learning experiences for policymakers and educators.
Practice-Based Knowledge Perspectives of Cultural Competence in Australian Financial Advice
Authors: Craft Amanda , Brimble Mark , Cull Michelle , MacDonald Kirsten , Hunt Katherine 
Published: February 2025

Abstract
Cultural competence has been cited as a key contributor to the pursuit of ethical and professional standards in a variety of professions (Tully 2020; Osborn & Karandikar 2023). There has, however, been little attention in the literature on the implications of cultural competence concerning the provision of financial advice. The discussion about the operationalisation of culturally aware approaches and behaviours in professional advice settings may be advanced by using practice-based knowledge. This qualitative study is a first attempt to assemble the experiences and insights of financial advice professionals across Australia to identify key aspects of adapting to the cultural diversity of Australian society. The experiences and views of 21 Australian financial advisers from various backgrounds using a combination of narrative and thematic analytic methodologies was applied. Four distinct themes were identified within the separate domains of 1) lack of visible diversity, 2) concerns of bias and labels, 3) perceived limitations and challenges in cultural competence, and 4) pathways to acquiring cultural competence. We conclude that the profession needs to do more to lift the cultural confidence and competence of financial advice practitioners.
Ubiquitin-specific peptidase 14 promotes neuron injury by stabilizing acyl-CoA synthetase long-chain family member 4 through deubiquitination
Authors: Hao Xiaoting , Liu Ying 
Published: February 2025

Objective:
Ubiquitin-specific peptidase 14 (USP14) may be a target for stroke treatment. Our study aims to explore the molecular mechanism of USP14 in the stroke process.

Material and Methods:
A stroke cell model was constructed using oxygen–glucose deprivation/reoxygenation (OGD/R)-induced SK-N-SH cells, and cell growth was assessed using cell counting kit 8 assay, EdU assay, and flow cytometry. Proinflammatory cytokine levels were tested through an enzyme-linked immunosorbent assay. The levels of USP14 and acyl-CoA synthetase long-chain family member 4 (ACSL4) were determined through Western blot and quantitative real-time polymerase chain reaction, whereas the interaction of USP14 and ACS14 was evaluated by co-immunoprecipitation assay.

Results:
OGD/R-induced SK-N-SH cell injury by enhancing ferroptosis and the knockdown of USP14 inhibited OGD/R-induced cell inflammation, apoptosis, and ferroptosis. Moreover, USP14 enhanced ACSL4 protein expression through deubiquitination. ACSL4 silencing mitigated neuron injury, and ACSL4 upregulation abolished USP14 knockdown-mediated inhibition of neuron injury.

Conclusion:
USP14 can enhance neuron injury through stabilizing ACSL4 protein expression.

Authors: Devi Saravanan Nandhini , Hogade Anil Pandharinath , Biradar Prakash R 
Published: February 2025

Objective:
The objective is to evaluate cilnidipine and compare it with fluoxetine on the depression model in male Swiss mice, utilising the tail suspension test and locomotor activity test.

Materials and Methods:
The animals were categorised into four groups, each consisting of six individuals (n = 6 per group). The subjects were given the test drug doses of cilnidipine at 5 mg/kg and 10 mg/kg, as well as fluoxetine at 10 mg/kg, for a duration of 21 days through an intraperitoneal route. On days 1, 14 and 21, the locomotor activity was assessed using the actophotometer, while the antidepressant activity was assessed using the tail suspension test (TST). The duration of immobility was assessed using the total sleep time method for a 5-minute period, while the number of counts was monitored for 10 min using an actophotometer.

Results:
Cilnidipine at a dosage of 10 mg/kg demonstrates a reduction in symptoms of depression when compared to the standard control. Neither cilnidipine 5 mg/kg nor 10 mg/kg resulted in a noteworthy decrease in locomotor activity.

Conclusion:
The present study demonstrated a substantial antidepressant effect of cilnidipine 10 mg/kg dosage. More research is needed to validate the results reported.
