Electromagnetic properties of vector doubly charmed tetraquark states
No full textWe conduct a systematic study of the electromagnetic properties of multiquark systems with undetermined internal structures. Motivated by the recent observation of the T+cc state, we apply the light-cone version of the QCD sum rule method to extract the magnetic dipole moments of several possible doubly charmed vector tetraquark states. When analyzing the magnetic dipole moment of these states, they are modeled to have the diquark-antidiquark configurations. The magnetic dipole moments for the members are extracted as and mu Tccss = 1.44+0.53-0.41 mu N. Comparing the results obtained for the magnetic dipole moments of the Tccu d state with the Tccu s state, the U symmetry is seen to be broken at about 15%, while, for the Tccdd and Tccss states, this symmetry is minimally broken. The obtained results may be useful to determine the true nature of these new interesting states.Iran National Science Foundation (INSF) [4025036]K.

In this study, in which pre-test-post-test control group experimental design was used, individuals who were in the same stage of the rehabilitation programme carried out by the Provincial Health Directorate AMATEM clinic for the target group were stratified and random assignment was made to three groups within these strata. As data collection tools, "Addiction Profile Index Sociodemographic Information Form", "Brief Symptom Inventory", Addiction Profile Index (BAPI), "Addiction Profile Index Clinical Form (BAPI-K)" were used. Cannabis Ladder and Cannabis Craving Scale Short Form' were used. In the study, MG-based individual interviews were conducted with individuals with cannabis use problems, and if they were in the experimental group, in addition to these interviews, a WEB-CC intervention containing short voice messages appropriate to the change stages of individuals was applied. Individuals who did not have internet access or had technical problems were included in the control group. The control group received a face-to-face motivational interview and two voicemails with only general information about cannabis use, while individuals in the second control group on the waiting list received only pre- and post-tests. This study examined the effects of a web-based self-help model based on motivational interviewing. Split-Plot ANOVA and Bonferroni tests were used to evaluate the effectiveness of the model. The results of the analyses showed a significant increase (p0.05). These findings showed that the web-based intervention studied had positive effects on certain behavioural and psychological parameters and that these effects were limited to the experimental group. The results showed significant improvement on the Cannabis Craving and Change stages in the experimental group, indicating that this motivational interviewing-based approach can positively change behaviours related to cannabis use.Participants were randomly assigned to two control groups and one experimental group based on their levels of craving and stages of change.

A case for peace education through science fiction: migration
No full textGiven the increasing popularity of the science-fiction genre, its capacity for worldbuilding and its long-duree vision, coupled with both the difficulty of discussing issues of migration in today's world as something more than a problem of the present and the necessity to go beyond this presentism, the author argues that science-fiction films provide an excellent tool for peace education inside and outside the classroom in general and to address migration in particular. This article discusses the why and how of using science fiction films for peace education, which the author claims is not necessarily taught in the classroom or special programs but should also be seen as part of lifelong learning/continuous education
Determination of Optimum Coordinate Transformation Parameters for GNSS and LiDAR-Based Localization in Automated Vehicles
No full textLocalization is one of the most critical components of automated vehicles (AVs). Although the positioning process in AVs is commonly carried out with global navigation satellite systems (GNSS), which offer a global solution, supportive or alternative location determination methods are needed due to the low accuracy of GNSS systems in urban areas, tunnels, etc. Laser Detection and Ranging -Simultaneous Localization and Mapping (LiDAR-SLAM) is an alternative localization method that provides the AV's local coordinates. This work aimed to verify the AV's localization by finding the accurate coordinate transformation parameters (CTPs) of trajectories acquired using the GNSS and LiDAR-SLAM technologies. We used the Conditional Adjustment with an Unknown Model (CAUM), Total Least Square (TLS), and Umeyama (UM) transformation methods to find the CTPs between the two sets of data. In order to address insoluble scenarios and enhance the efficiency of transformation, the voxel-based approach was developed, including the CAUM, TLS, and UM methods for each voxel. The results are discussed in terms of the performance comparison of the methods, the success of the voxel-based approach, and usability in real-time scenarious.Scientific and Technological Research Council of Trkiye (TBIdot;TAK)No Statement Availabl
Properties of doubly heavy spin-12 baryons: The ground and excited states
No full textWe determine the masses and residues of the ground and excited spin -12 baryons consist of two heavy b or c quark utilizing the QCD sum rule formalism. In the calculations, we consider the nonperturbative operators up to ten mass dimensions in order to increase the accuracy compared to the previous calculations. We report the obtained results for both the symmetric and antisymmetric currents defining the doubly heavy baryons of the ground state (1S), first orbitally excited state (1P), and first radially excited state (2S). We compare our results with the predictions of other nonperturbative approaches as well as existing experimental data which is available only for the ground state of cc channel. These predictions can help the experimental groups in their searches for all members of the doubly heavy baryons in their ground and exited states.Iran National Science Foundation (INSF) [4025036]The authors thank H.

Noncoprime action of a cyclic group
No full textLet A be a finite nilpotent group acting fixed point freely on the finite (solvable) group G by automorphisms. It is conjectured that the nilpotent length of G is bounded above by l(A), the number of primes dividing the order of A counted with multiplicities. In the present paper we consider the case A is cyclic and obtain that the nilpotent length of G is at most 2l(A) if vertical bar G vertical bar is odd. More generally we prove that the nilpotent length of G is at most 2l(A) + c(G; A) when G is of odd order and A normalizes a Sylow system of G where c(G; A) denotes the number of trivial A-modules appearing in an A-composition series of G.

Seismic performance and damage assessment of bridges during the 2023 Kahramanmaras, Türkiye earthquakes (Mw = 7.8, Mw = 7.6)
No full textThis article presents a summary of the damage observed in bridges in the regions affected by the 6 February 2023 Kahramanmaras, T & uuml;rkiye earthquake sequence. A bridge database was developed based on the observations from multiple reconnaissance groups that visited the bridges. These reconnaissance groups collectively visited 140 individual bridges that were subjected to various intensities of ground shaking. The severity of the observed damage ranged from no damage to total collapse. The types of damage to bridge components mainly included cracking and shifting of abutments, failure of pier cap shear blocks, shifting or dislodging of bearing pads, cracking of girders and loss of prestress, plastic hinging at pier bases, residual pier drift, and distress to deck surfaces, handrails, and carried utilities. Recorded and estimated seismic intensity measures are presented for each bridge site, and statistical information and correlations were developed considering the intensity of shaking, bridge parameters, and observed damage. Observations from a few visited sites are presented as case studies to illustrate the common failure mechanisms. The bridge database and presented results are expected to serve as a reference for further analysis, such as statistical verification, correlation, or damage estimations, and discussion regarding the mitigation of the observed vulnerabilities of bridges in T & uuml;rkiye and those with similar construction worldwide.Scientific and Technological Research Council of Turkiye, 1002C-Rapid Support Program for Natural Disaster [123D036]; Earthquake Engineering Research Institute; Geotechnical Extreme Events Reconnaissance AssociationThe author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This research was in part funded by The Scientific and Technological Research Council of Turkiye, 1002C-Rapid Support Program for Natural Disaster (project no.123D036).

The investigation of printing parameters effect on tensile characteristics for triply periodic minimal surface designs by Taguchi
No full textThe advent of additive manufacturing also referred to as 3D printing, has brought about substantial changes in the industrial domain, as it possesses the capability to fabricate intricate items with enhanced cost-efficiency and productivity. Fused Filament Fabrication (FFF) is a 3D printing process that has gained significant popularity due to its versatile capabilities and cost-effectiveness. This paper investigates the impact of the printing parameters on the tensile characteristics of Triply Periodic Minimal Surface (TPMS) manufactured using FFF 3D printing. TPMS patterns have unique geometric properties and potential applications, making them an intriguing subject of study. The behavior of three different TPMS lattices with three printing parameters is investigated. Finding the best testing settings is done with the Taguchi method, and the data is analyzed with the Analysis of Variance (ANOVA) test. TPMS pattern was found to be the most effective parameter with 83.78%. While the highest strength was obtained in Schwarz diamond, the highest energy absorption was observed in the Gyroid structure. The contributions of printing parameters to tensile strength are line thickness, printing speed, and layer height, respectively. As line width and printing speed increase, both energy absorption and strength increase. Therefore, 0.40 mm line width and 60 mm/s printing speed give optimum values. When considered for energy absorption, the optimum value is 0.20 mm layer height, while when considered for strength, 0.10 mm layer height is the optimum value. The findings emphasize the importance of optimizing printing parameters for desired mechanical characteristics in 3D printed components and highlight the potential of TPMS structures in various applications. This research contributes to the growing knowledge in additive manufacturing and provides insights into optimizing FFF 3D printing for improved mechanical performance
