Magneto-optical conductivity and giant Faraday-Kerr rotation in Floquet topological insulators

We study the surface state-dependent magneto-optical properties of an ultrathin Floquet topological insulator (FTI) under the inﬂuence of an external perpendicular magnetic ﬁeld in the terahertz frequency regime. Under the Floquet picture, we treat the circularly polarized off-resonant light as an external perturbation that introduces a mass gap at the Dirac cone, thus, making the surface state Dirac fermions massive. By tuning the optical ﬁeld energy in the FTI thin-ﬁlm system, various electronic phase transitions can be driven between the trivial insulator state and the band insulator state. Using Kubo formalism, we derive the real and imaginary parts of the longitudinal and Hall conductivities and demonstrate that these conductivities are sensitively inﬂuenced by the strength of the off-resonant optical ﬁeld, magnetic ﬁeld, and chemical potentials. On the other hand, topological insulators exhibit strong magneto-optic effects. We further compute the Kerr and Faraday rotation angles and show that giant Kerr and Faraday rotations can be achieved in a FTI thin ﬁlm by external tuning knobs, such as magnetic and off-resonant optical ﬁelds. The Kerr and Faraday rotations in symmetric (top) and antisymmetric (bottom) topological surface states can be controlled for interband and intraband transitions via gate bias voltage. Our results reveal the FTI as an intriguing versatile system whose magneto-optical properties can be effectively tuned optically, magnetically and electrically, thus, uncovering the strong photonics and optoelectronics device application potentials of the FTI.

Learning Model Inquiry-Based Local Wisdom Dilemmas Stories and Their Effects on Critical Thinking and Scientific Writing Abilities

The findings of this study reveal a mismatch between competence criteria and the reality of students' critical thinking and scientific writing abilities. As a result, it is critical to find a solution to this problem as soon as possible. This study aims to implement the inquiry-based learning model of local wisdom dilemmas stories (ILWDS) and examine its effect on improving critical thinking and writing abilities. The research design is a quasi-experimental pretest-posttest control group design. The research sample consisted of 2 senior high schools—the samples consisted of 62 students in the experimental and 62 in the control group. Data on students' critical thinking abilities were obtained through test instruments. The data obtained were analyzed descriptively and inferentially using MANOVA. Additional studies to evaluate the number of the treatment's effects on the capacity to think critically and write scientifically used Cohen's d equation. The results showed that the mean score of the experimental group's critical thinking abilities and scientific writing was higher than that of the control group. The results of the MANOVA analysis show that there is a significant influence of the ILWDS learning model on students' critical thinking abilities and scientific writing. This model is effective in the high category. Therefore, the ILWDS learning model is recommended to be applied in senior high schools which need help improving critical thinking abilities and scientific writing.

Which Value Supports Pro-environmental Behavior? Future Direction for Pre-service Physics Teacher

Although a huge number of studies enhancing pro-environmental behavior (PEB), the environmental quality is still in poor condition. Enhancing PEB needs to consider some aspects, such as the value and location. Pre-service physics teachers have a role in shaping students’ PEB because environmental issues are part of the high school physics curriculum. This study aimed to investigate the link between the location, and values (biospheric, altruistic, egoistic, and hedonic), from two different locations in Indonesia. The modified and translated 2-MEV, and E-PVQ scales were used. This study concluded that the values in both locations are in the very high category, in which the values are correlated to PEB. The strongest correlated value is an egoistic value that is related to the self-enhancement indicating the need for self-enhance approaches in the class to promote PEB. The different locations which are in the same country didn’t show a significant difference in both values and PEB. Thus, future study could conduct their research in a larger area with a different culture to explore the relationship between PEB with location or other demographic aspects, and the development of activities to enhance PEB need to consider the strong relationship between PEB with egoistic value.
A cognitive model of individual variation in mathematics achievement in college students referred for learning difficulties

This study analyzed, via Structural Equation Modeling (SEM) the contribution of auditory long-term memory, auditory working memory, and reasoning to mathematics calculation and mathematics reasoning in a sample of 401 college-age students referred for assessment of possible learning difficulties. Three nested models were examined in an attempt to determine the differential effects of cognitive processes on mathematics calculation and mathematics reasoning. Measures were chosen from a comprehensive neuropsychological battery administered to individuals seeking evaluations at The University of Georgia – Regents’ Center for Learning Disorders (UGA-RCLD). Auditory long-term memory, auditory working memory, and reasoning contributed 14% and 44 % of the variance to mathematics calculation and mathematics reasoning, respectively. Nested model analyses failed to demonstrate differential contributions of variance to mathematics calculation and mathematics reasoning.

Anchoring transition of confined prolate hard spherocylinder liquid crystals: hard needle-wall potential

ABSTRACT In the present work, the effects of confinement on a system of hard spherocylinder (HSC) particles interacting with planar substrates through the hard needle-wall potential are studied via Monte Carlo simulation. The molecular volume absorbed at the substrates for the spherocylinder particles are calculated analytically and predicted the critical values of transition parameter from planar to homeotropic anchoring. The transition parameters are achieved from simulations for three particle’s elongations: , , and . The results are in agreement with the predicted values. In the range of small needle length , HSC particles at the first layer near the walls are perpendicular to the walls but in the second layer, are parallel to the walls. To describe this behaviour of HSC particles, we used a system of HSCs consists of two types of molecules: free liquid crystal molecules and fixed perpendicular substrate molecules. We show that the particles near the perpendicular HSCs substrates have parallel alignment. The results of HSCs with and are compared with the hard particle-wall potential. This long needle length interaction is similar to the hard wall potential. Also our results are corresponded to Barmes and Cleaver results on hard Gaussian overlap particles with and , qualitatively.

Use of injectable platelet rich fibrin (IPRF) as LDD vehicle containing doxycycline in periodontal Therapy – In vitro study

Purpose: Local drug delivery systems (LLD) are preferred over systemic antibiotic therapy in indicated cases to avoid unnecessary large doses of drug, development of antibiotic resistance etc. The search for the more suitable novel vehicle for the local drug delivery that can render controlled release of drug at periodontally infected sites are widely researched. i-PRF being autologous and injectable could be a suitable vehicle for local delivery of drugs. This study aims to evaluate the possibility of using i-PRF as a controlled release drug vehicle in periodontal therapy. Methods: i-PRF obtained from centrifugation of 10 ml of blood collected from volunteers are mixed with known concentration of doxycycline drug and allowed to become a gel. The drug loaded gel is dispensed in artificial saliva and allowed to degrade. At specific time intervals (1 hr, 3 hr, 5 hr, 7 hr, 3d, 5d, 7d, 9d, 14d) aliquot of the 200 microliter were collected from each sample and subjected for spectrophotometric analysis. Results: The spectrophotometric results show that the drug was detected in all the samples obtained from the 1 hr to the 14th day. Final concentration in the eluted samples seem to be gradually reducing from the 1 hr to the 7 th hour and a steep downward pattern in the concentration was absorbed from the 3 rd day until 14th day. Conclusions: The controlled drug release profile of the i-PRF shows its a potential and suitable vehicle for LDD system in periodontal therapy. Additionally, properties like the syringeability, in-situ gel formation, and autologous fibrin nature may facilitate its direct delivery into the periodontal pocket, getting moulded to the pocket shape with attachment to the soft and hard tissue thereby ensuring the retention of the drug loaded i-PRF in the confined pocket environment.
Reactive power compensation considering high harmonics generation from internal and external nonlinear load

The paper deals with reactive power compensation by means of condenser batteries with harmonic distortions in voltage and current, resulting from internal and external nonlinear load regarding the connection point shared by consumers. The paper presents the dependencies of the capacitor’s overloading factor from the required reactive power for compensating. These relations can help to determine in which capacity area of the capacitor banks its operation is ensured without overload. The paper also presents algorithm for selecting parameters of condenser batteries which leads to minimization of the capacitors overload and maximization of the network power factor.
Comparison of visual outcomes and higher order aberrations of wavefront-optimized and wavefront-guided myopic laser in-situ keratomileusis

To compare the visual and refractive outcomes of wavefront-optimized (WFO) ablations (wavelight allegretto) and wavefront-guided (WFG) ablations (VISX Custom Vue). Overall, two consecutive groups of eyes were treated for myopia and myopic astigmatism with laser in-situ keratomileusis. One group was treated with WFO ablation and the other group was treated with WFG ablation. Preoperative and 1, 3 and 6 months postoperative refractive evaluation (efficacy, safety, predictability, accuracy, stability, and refractive astigmatism), higher order aberrations (HOAs), and contrast sensitivity were analyzed. The WFO group comprised 20 eyes of 11 patients and the WFG group comprised 34 eyes of 17 patients. Postoperatively, the mean refractive spherical equivalent was −0.21±0.30 D in WFO group and −0.23D±0.57 D in WFG group. The mean values for postoperative uncorrected distance visual acuity were 0.93±0.15 and 0.96±0.16 in WFO and WFG groups, respectively. Safety index was 1.11 in WFO group and 1.17 in WFG group. Six months postoperatively, in WFO group, the induced HOA root mean square (RMS) was 0.25±0.21 μm (P=0.007), induced coma RMS was 0.07±0.23 μm (P=0.84), and induced spherical aberration RMS was 0.03±0.12 μm (P=0.467), whereas induced trefoil RMS was −0.09±0.23 μm (P=0.003). In WFG group, induced HOA RMS was 0.9±0.11 μm (P=0.002), induced coma RMS was 0.01±0.30 μm (P=0.065), and induced spherical aberration RMS was 0.09±0.17 μm (P=0.214), whereas induced trefoil RMS was 0.04±0.15 μm (P=0.005). Contrast sensitivity testing showed a statistically significant improvement in both groups at low spatial frequencies test. Both WFG and WFO showed comparable accuracy, efficacy, and safety with nearly equal induction of all HOA.
Self-evaluation of Physical Education Teacher

Changes in the level of teacher competency are continually improved through evaluation, ensuring that the learning that is applied to students remains innovative. The goal of this study was to discover physical education teachers' self-evaluation of teaching effectiveness. This study is descriptive that employs the survey approach. Fifty-one elementary school physical education teachers in South Sulawesi Province (aged 20 to 58 years) volunteered to participate in this study. The Self-Evaluation of Teacher Effectiveness Questionnaire in Physical Education (SETEQ-PE) was utilized in this study to assess teacher effectiveness in teaching physical education. This efficacy is measured using six components: learning environment, teacher and student evaluation, application of learning content, use of technology, teaching methodologies, and lesson execution. The findings revealed that the overall average physical education teachers' teaching effectiveness score was in the high range (140). In terms of gender, male instructors have a high average score (139.5), whereas female teachers have a very high average score (139.5). (142). Even though female teachers have a higher score than male teachers, there is no significant difference in their scores, with a significance value of 0.731. Given the small sample size of this study, additional research should be undertaken on a broader scale to investigate other aspects that may influence teaching effectiveness.
Low Carbon City Pilot Policy and Corporate Innovation

The "Double Carbon" target cannot be achieved without energy saving and carbon reduction in urban units, and corporate innovation is indispensable for cities to achieve energy saving and carbon reduction. Based on the data of Chinese A-share firms listed on Shanghai and Shen Stock Exchange over the period of 2007–2020, this paper explores the impact of low-carbon city pilot policies on enterprise innovation using the DDD method, and further refines the substantive and strategic aspects of the impact on enterprise innovation, and explores the heterogeneity of enterprise ownership nature and size. The study finds that, first, the pilot low-carbon city policy significantly promotes corporate innovation and has a slightly higher positive incentive effect on substantive innovation than strategic innovation. Second, non-state corporations and large-scale corporations tend to enhance substantive innovation while state-owned corporations and small-scale corporations tend to engage in strategic innovation activities as a result of the pilot policy.
Variations of the Moist Static Energy Budget of the Tropical Indian Ocean Atmospheric Boundary Layer

AbstractThe atmospheric circulation depends on poorly understood interactions between the tropical atmospheric boundary layer (BL) and convection. The surface MSE source (130 W m−2, of which 120 W m−2 is evaporation) to the tropical marine BL is balanced by upward MSE flux at the BL top that is the source for deep convection. Important for modeling tropical convection and circulation is whether MSE enters the free troposphere by dry turbulent processes originating within the boundary layer, or by motions generated by moist deep convection in the free troposphere. Here, highly resolved observations of the BL quantify the MSE fluxes in approximate agreement with recent cloud-resolving models, but the fluxes depend on convective conditions. In convectively suppressed (weak precipitation) conditions, entrainment and downdraft fluxes export equal shares (60 W m−2) of MSE from the BL. Downdraft fluxes are found to increase 50%, and entrainment to decrease, under strongly convective conditions. Variable entrainm.
Transverse beam profile reconstruction using synchrotron radiation interferometry

Transverse beam size measurements in new generation of synchrotron light sources is a challenging task due to their characteristic small beam emittances and low couplings. Since the late 1990s, synchrotron radiation interferometry (SRI) has been used in many accelerators to measure the beam size through the analysis of the spatial coherence of the synchrotron light. However, the standard SRI using a double-aperture system provides the beam size projection in a given direction. For this reason, the beam shape is not fully characterized because information about possible transverse beam tilts is not determined. In this report, we describe a technique to fully reconstruct the transverse beam profile based on a rotating double-pinhole mask, together with experimental results obtained at ALBA under different beam couplings. We also discuss how this method allows us to infer ultrasmall beam sizes in case of limitations of the standard SRI.

The Vergence-Accommodation Conflict in Stereoscopic Environments: A Comparison of Theoretical and Gaze-Based Vergence Angle

The utilization of 3D displays has become significant in various fields such as vision research, medical imaging, surgical training, scientific visualization, virtual prototyping, and other related applications. In many of these applications, it is necessary for the graphic image to accurately depict the 3D structure of the portrayed object. Unfortunately, the perception of 3D structures in 3D displays is often distorted by the reality depicted in the displays. The effects of these conflicts may affect binocular fusion and may cause visual fatigue. The extensive study of the vergence-accommodation conflict has shed light on the distortion in 3D structure. In this study, the aim was to investigate this phenomenon by comparing the theoretical eye vergence angle with the gaze-based eye vergence angle using eye tracker gaze data. The findings showed that the gaze-based eye vergence angle was largest at the greatest parallax, indicating a correlation between parallax and vergence angle. Furthermore, the results revealed that the accuracy of the eye vergence angle was highest at the nearest parallax, suggesting that virtual objects placed closer to the screen and in the middle generally exhibited improved accuracy. These findings contribute to a better understanding of the vergence-accommodation conflict in stereoscopic environments, providing insights that can inform the design and development of virtual reality systems.
What is the final size of turbulent mixing zones driven by the Faraday instability?

Miscible fluids of different densities subjected to strong time-periodic accelerations normal to their interface can mix due to Faraday instability effects. Turbulent fluctuations generated by this mechanism lead to the emergence and the growth of a mixing layer. Its enlargement is gradually slowed down as the resonance conditions driving the instability cease to be fulfilled. The final state corresponds to a saturated mixing zone in which the turbulence intensity progressively decays. A new formalism based on second-order correlation spectra for the turbulent quantities is introduced for this problem. This method allows for the prediction of the final mixing zone size and extends results from classical stability analysis limited to weakly nonlinear regimes. We perform at various forcing frequencies and amplitudes a large set of homogeneous and inhomogeneous numerical simulations, extensively exploring the influence of initial conditions. The mixing zone widths, measured at the end of the simulations, are satisfactorily compared to the predictions, and bring a strong support to the proposed theory. The flow dynamics is also studied and reveals the presence of sub-harmonic as well as harmonic modes depending on the initial parameters in the Mathieu phase diagram. Important changes in the flow anisotropy, corresponding to the large scale structures of turbulence, occur. This phenomenon appears directly related to the orientation of the most amplified gravity waves excited in the system, evolving due to the enlargement of the mixing zone.
Specialized Content Knowledge Lower Secondary School Teachers on Quadrilaterals

The teachers' knowledge of specific content has a positive relationship with the students' mathematics achievement. Mathematics teachers must have an appropriate level to ensure mathematics learning effectively. The quadrilateral is one of the essential contents in geometry. However, many teachers did not successfully deliver and teach this content in classroom instruction. Therefore, this qualitative study explores the specialized content knowledge of lower secondary teachers in defining and classifying quadrilaterals. Four teachers, two male and two female teachers, were recruited to become participants in this work. All participants have similar teaching experience and do not hold an educator certificate. A test and semi-structured interviews were assigned to obtain specialized content knowledge of the teachers on quadrilaterals. The interview data were analyzed in three stages: data condensation, data presentation, and conclusion drawing. The findings show that only one teacher understands hierarchically in defining and classifying quadrilaterals, two teachers are at the partial prototype level because they cannot see the hierarchical relationship between the quadrilaterals, and another teacher is at the prototype understanding level because it relies on the prototype of quadrilaterals' shape. These findings suggest that lower secondary teachers' special content knowledge of quadrilateral needs to be strengthened through workshops and training professional development.
