AbstractObjectives This Study Aimed To Find The Relationship Between Lack Of Knowledge And Self-Awareness About Temporomandibular Disorders (Tmds) And Their Signs And Symptoms Among Dental Students Of College Of Dentistry, Jazan University, Jazan, KSA.
Materials and Methods A self-administered structured questionnaire was used to assess the demographic variables, information regarding self-awareness and knowledge about TMDs among dental students. The data obtained were subjected to statistical analysis using the IBM SPSS version 20.0 software.
Statistical Analysis The data obtained were subjected to statistical analysis using the IBM SPSS version 20.0 software. Descriptive statistics, that is, frequencies and percentages were computed. The comparative analysis was done using Chi-square statistical analysis.
Results Out of 406 participants, 44.08% were male and 55.91% were female. Also, 329 were undergraduate students and 77 were interns. Almost a similar percentage of undergraduates and interns were suffering with trismus, articular sounds, pain, and arthralgia. Interns had more incidence of injuries of the head and neck, and had undergone orthodontic treatment, with a significant difference statistically (p < 0.05). A significant relation (p < 0.05) was observed between responses, with interns having better knowledge regarding investigations and treatment interventions.
Conclusion A direct relationship exists between the level of knowledge about temporomandibular joint (TMJ) and TMDs and self-awareness of its signs and symptoms. A thorough knowledge is required among the students to investigate, diagnose, and treat TMDs at early stages.

Published: January 2023

AbstractGenetic influences are critical for determining mandibular protrusion in class IIImalocclusion cases, and growth hormone receptors (GHRs) are thought to have an essential impact on craniofacial bone growth. This review aimed to assess the association between GHR gene polymorphism variants and mandibular morphology. Studies were extensively searched using PubMed and Google Scholar until December 2020. The study design according to PECOS was: P, class III malocclusion; E, GHR polymorphism; no polymorphism in C, GHR; O, linear dimensional changes in maxillary and mandibular measurements; and S, cross-sectional and case-control studies. Selected studies were of acceptable methodological quality on a 10-point scale. A preliminary search identified 107 studies; after excluding duplicate abstracts, 63 studies were screened. Nine studies were subsequently included in the systematic review. Conclusion Polymorphic variants at rs6180, rs6182, and rs6184 in the GHR gene were associated with condylion-gonion measures in Asians and Turks but not in Colombians and Egyptians.
Do personal values and motivation affect women’s solo travel intentions in Taiwan?
Authors: Teng Yi-Man , Wu Kun-Shan , Lee Ying-Chieh 
Published: January 2023

AbstractFemale solo travel is experiencing a global increase and specifically, gaining popularity in Asia. This study explores how personal values and female solo travel motivation affect travel behavior. Using a sample comprising 381 single females in Taiwan, partial least squares structural equation modeling was utilized to investigate the hypotheses. The results revealed Hypothesis 1 and Hypothesis 3 are supported, which verifies personal internal values significantly affect female solo travel motivation, and are identified as significant factors influencing female solo travel intention. Additionally, Hypothesis 5 is partially support, indicating the female solo travel motivations of escape/relaxation, relationship, and self-actualization contribute to the formation of positive female solo travel intention. As Hypothesis 2 and Hypothesis 4 are unsupported, external values have no impact on female solo travel motivation or any significant effect on female solo travel intention. This research adds to the vast gap in tourism literature by identifying the personal values and motivations of female solo travel, and benefits the development of the female solo travel market.
Controlling feral ruminants to reduce greenhouse gas emissions: a case study of buffalo in northern Australia
Authors: Davies Hugh F. , Murphy Brett P. , Duvert Clément , Neave Georgina 
Published: January 2023

Context The bourgeoning carbon economy is creating novel ways to incentivise conservation management activities that have the co-benefits of reducing greenhouse gas (GHG) emissions and social inequality. Aim To estimate the monetary value of carbon credits that landowners could generate by reducing ecologically destructive feral populations of the Asian water buffalo (Bubalus bubalis) in northern Australia. Methods First, we estimated buffalo enteric emissions based on the population structure of feral buffalo in northern Australia, and discounted the reduction of fire emissions due to the consumption of grassy fuel by feral buffalo. We then predicted the change in buffalo population size across the South Alligator River region of Kakadu National Park under four buffalo management scenarios: (1) no buffalo control; (2) low-intensity buffalo control; (3) moderate-intensity buffalo control; and (4) high-intensity buffalo control. We quantified the reduction of GHG emissions under the three buffalo control scenarios, relative to the scenario of no buffalo control, while discounting the GHG emissions that directly result from buffalo control actions (e.g. helicopter emissions). Key results All three buffalo control scenarios substantially reduced the estimated GHG emissions that would otherwise have been produced. The low-intensity buffalo control scenario was predicted to abate 790 513 t CO2-e over the 20-year simulation, worth USD15 076 085 (or USD753 804 year−1). Our high-intensity buffalo control scenario had the greatest reduction in GHG emissions, with a total net abatement of 913 231 t CO2-e, worth USD17 176 437 (or USD858 822 year−1). Conclusions The potential value of carbon credits generated by controlling feral buffalo populations in northern Australian savannas far exceeds the management costs. Implications The management of feral ruminants could be incentivised by the generation of carbon credits. Such management could simultaneously avoid GHG emissions, generate income for landowners and offer significant ecological benefits.
Water dissociation at the water–rutile TiO

The interaction of water with TiO
2
surfaces is of crucial importance in various scientific fields and applications, from photocatalysis for hydrogen production and the photooxidation of organic pollutants to self-cleaning surfaces and bio-medical devices. In particular, the equilibrium fraction of water dissociation at the TiO
2
–water interface has a critical role in the surface chemistry of TiO
2
, but is difficult to determine both experimentally and computationally. Among TiO
2
surfaces, rutile TiO
2
(110) is of special interest as the most abundant surface of TiO
2
’s stable rutile phase. While surface-science studies have provided detailed information on the interaction of rutile TiO
2
(110) with gas-phase water, much less is known about the TiO
2
(110)–water interface, which is more relevant to many applications. In this work, we characterize the structure of the aqueous TiO
2
(110) interface using nanosecond timescale molecular dynamics simulations with ab initio-based deep neural network potentials that accurately describe water/TiO
2
(110) interactions over a wide range of water coverages. Simulations on TiO
2
(110) slab models of increasing thickness provide insight into the dynamic equilibrium between molecular and dissociated adsorbed water at the interface and allow us to obtain a reliable estimate of the equilibrium fraction of water dissociation. We find a dissociation fraction of 22 ± 6% with an associated average hydroxyl lifetime of 7.6 ± 1.8 ns
.
These quantities are both much larger than corresponding estimates for the aqueous anatase TiO
2
(101) interface, consistent with the higher water photooxidation activity that is observed for rutile relative to anatase.
Neutron shielding assessment of a 16O hadron therapy room by means of Monte Carlo simulations with the PHITS code

Published: January 2023

Abstract
Hadron radiation therapy is of great interest worldwide. Heavy-ion beams provide ideal therapeutic conditions for deep-seated local tumours. At the Heidelberg Ion Beam Therapy Center (HIT, Germany), protons and carbon ions are already integrated into the clinical routine, while 16O ions are still used for research only. To ensure the protection of the technical staff and members of the public, it is required to estimate the neutron dose distribution for optimal working conditions and at different locations. The Particle and Heavy Ion Transport Code System (PHITS) is used in this work to evaluate the dose rate distribution of secondary neutrons in a treatment room at HIT where 16O ions are used: an equivalent target in soft tissue is considered in the shielding assessment to simulate the interaction of the beam with patients. The angular dependence of neutron fluences and energy spectra around the considered phantom were calculated. Alongside the spatial distribution of the neutron and photon fluence, a map of the effective dose rate was estimated using the ICRP fluence-to-effective dose conversion coefficients, exploiting the PHITS code’s built-in capabilities. The capability of the actual shielding design of the studied HIT treatment room was approved.

Authors: Friedman Isaac , Riaño Oscar , Roudenko Svetlana , Son Diana , Yang Kai 
Published: January 2023

Abstract
We consider two types of the generalized Korteweg–de Vries equation, where the nonlinearity is given with or without absolute values, and, in particular, including the low powers of nonlinearity, an example of which is the Schamel equation. We first prove the local well-posedness of both equations in a weighted subspace of H
1 that includes functions with polynomial decay, extending the result of Linares et al (2019 Commun. Contemp. Math.
21 1850056) to fractional weights. We then investigate solutions numerically, confirming the well-posedness and extending it to a wider class of functions that includes exponential decay. We include a comparison of solutions to both types of equations, in particular, we investigate soliton resolution for the positive and negative data with different decay rates. Finally, we study the interaction of various solitary waves in both models, showing the formation of solitons, dispersive radiation and even breathers, all of which are easier to track in nonlinearities with lower power.
Variational principles for topological pressures on subsets
Authors: Zhong Xing-Fu , Chen Zhi-Jing 
Published: January 2023

Abstract
In this paper, we investigate the relations between various types of topological pressures and different versions of measure-theoretical pressures. We extend Feng–Huang’s variational principle for packing entropy to packing pressure and obtain two new variational principles for Pesin–Pitskel and packing pressures respectively. We show that various types of Katok pressures for an ergodic measure with respect to a potential function are equal to the sum of measure-theoretic entropy of this measure and the integral of the potential function. Moreover, we obtain Billingsley type theorem for packing pressure, which indicates that packing pressure can be determined by measure-theoretic upper local pressure of measures, and a variational principle for packing pressure of the set of generic points for any invariant ergodic Borel probability measure.

Published: January 2023

Abstract
The generation of entanglement between remote matter qubits has developed into a key capability for fundamental investigations as well as for emerging quantum technologies. In the single-photon, protocol entanglement is heralded by generation of qubit-photon entangled states and subsequent detection of a single photon behind a beam splitter. In this work we perform a detailed theoretical and experimental investigation of this protocol and its various sources of infidelity. We develop an extensive theoretical model and subsequently tailor it to our experimental setting, based on nitrogen-vacancy centers in diamond. Experimentally, we verify the model by generating remote states for varying phase and amplitudes of the initial qubit superposition states and varying optical phase difference of the photons arriving at the beam splitter. We show that a static frequency offset between the optical transitions of the qubits leads to an entangled state phase that depends on the photon detection time. We find that the implementation of a Charge-Resonance check on the nitrogen-vacancy center yields transform-limited linewidths. Moreover, we measure the probability of double optical excitation, a significant source of infidelity, as a function of the power of the excitation pulse. Finally, we find that imperfect optical excitation can lead to a detection-arm-dependent entangled state fidelity and rate. The conclusion presented here are not specific to the nitrogen-vacancy centers used to carry out the experiments, and are therefore readily applicable to other qubit platforms.

Published: January 2023

Abstract
In general description of the Raychaudhuri equation it is found that this first order non-linear differential equation can be written as a second order linear differential equation in the form of Harmonic Oscillator with varying frequency. Further, the integrability of the Raychaudhuri equation has been studied and also the expansion scalar is obtained in an explicit form. Subsequently, f(R) gravity theory has been studied in the background of inhomogeneous FLRW spacetime with an aim to formulate the Raychaudhuri equation. A congruence of time-like geodesics has been investigated using the Raychaudhuri equation to examine whether the geodesics converge or not and some possible conditions are determined to avoid singularity. Finally, a brief quantum description has been presented.
Tunable optical multistability and absorption in a hybrid optomechanical system assisted by an auxiliary cavity and quantum dot molecules
Authors: Yadav Surabhi , Bhattacherjee Aranya B 
Published: January 2023

Abstract
Coherent and tunable light-matter interaction in cavity quantum electrodynamics (C-QED) has attracted much attention for its fundamental importance and applications in emerging areas of quantum technologies. In this work, we propose a hybrid C-QED system comprising embedded quantum dot molecules (QDMs) in a primary photonic crystal (PhC) optomechanical cavity, which is further coupled to an auxiliary PhC cavity via a single-mode waveguide. We investigate the effect of the QDMs, mechanical oscillator, and the feedback from the auxiliary cavity on the multistability response shown by the mean intracavity photons in the primary optomechanical cavity. Tuning the various system parameters can control optical multistability. We further study the absorption spectra showing distinct characteristics of negative absorption (transparency dip), which strongly depend on mechanical resonator frequency. Thus, the proposed model is valuable for practically realizing efficient all-optical switching devices at low power and in various other quantum sensing devices.

Published: January 2023

Abstract
In this study, a highly angular sensitive surface plasmon resonance (SPR) biosensor has been designed for cancer cell detection. The proposed surface plasmon resonance biosensor structure is based on Kretschmann configuration, which works on an angular interrogation technique. The proposed SPR biosensor has enormous possibility to detect the various kind of cancer cells. The refractive index alteration of different cancerous (skin, cervical and blood) cells is 1.360–1.390. The proposed SPR biosensor is stacked with multilayers having CaF2 prism, silver metal, bismuth telluride (Bi2Te3) and MXene (Ti3C2Tx) layers. The performance parameters like angular sensitivity, quality factor, detection accuracy, and electric field intensity distribution have been optimized in this article. Here, various kind of cancer cells (skin, cervical and blood) have been also analyzed and corresponding angular sensitives are 252.20, 305.70 and 319.46 deg R−1IU−1 respectively. The proposed SPR biosensor shows best results for blood cancer cell detection. Some other important performance parameters like detection accuracy, quality factor, and electric field intensity distribution have also been calculated for proposed SPR biosensor device. The simulation results have been performed by MATLAB 2019a software. The proposed SPR biosensor design may open a new way for the medical industry.

Published: January 2023

AbstractObjective.Previous studies have demonstrated that transcranial ultrasound stimulation (TUS) with noninvasive high penetration and high spatial resolution has an effective neuromodulatory effect on neurological diseases. Attention deficit hyperactivity disorder (ADHD) is a persistent neurodevelopmental disorder that severely affects child health. However, the neuromodulatory effects of TUS on ADHD have not been reported to date. This study aimed to investigate the neuromodulatory effects of TUS on ADHD.Approach.TUS was performed in ADHD model rats for two consecutive weeks, and the behavioral improvement of ADHD, neural activity of ADHD from neurons and neural oscillation levels, and the plasma membrane dopamine transporter and brain-derived neurotrophic factor (BDNF) in the brains of ADHD rats were evaluated.Main results.TUS can improve cognitive behavior in ADHD rats, and TUS altered neuronal firing patterns and modulated the relative power and sample entropy of local field potentials in the ADHD rats. In addition, TUS can also enhance BDNF expression in the brain tissues.Significance. TUS has an effective neuromodulatory effect on ADHD and thus has the potential to clinically improve cognitive dysfunction in ADHD.

Authors: Sur U. 
Published: January 2023

Abstract
This paper proposes an efficient low cost mechanism to accurately measure the dielectric
dissipation factor and its allied effect over resin impregnated paper. The measuring circuit is a
modified De Sauty bridge network where the accurate parameter measurement can been performed. The
effect of stray capacitance over dielectric loss and dissipation factor has been nullified by the
application of operational amplifier in the circuit. Different samples of resin impregnated paper
have been tested based on their aging and moisture content to check the reliability of the
proposed measuring technique. Experimental result shows the efficacy of the proposed method when
compared to existing IEC and ASTM standard procedures and commercial measuring
devices. Measurement error analysis with repeatability and uncertainty calculation shows promising
result and is within the acceptable limits.

Abstract
The extracellular matrix (ECM) obtained by decellularization provides scaffolds with the natural complex architecture and biochemical composition of the target organ. Whole kidney decellularization by perfusion uses the vasculature to remove cells leaving a scaffold that can be recellularized with patient-specific cells. However, decellularization and recellularization are highly complex processes that require intensive optimization of various parameters. In pursuit of this, a huge number of animals must be sacrificed. Therefore, we used precision-cut kidney slices (PCKS) as a source of natural scaffolds, which were decellularized by immersion in chemical reagents allowing the examination of more parameters with less animals. However, chemical reagents have a damaging effect on the structure and components of the ECM. Therefore, this study aimed at investigating the effects of physical treatment methods on the effectiveness of PCKS decellularization by immersion in chemical reagents (CHEM). PCKS were treated physically before or during immersion in chemicals (CHEM) with high hydrostatic pressure (HHP), freezing–thawing cycles (FTC) or in an ultrasonic bath system (UBS). Biochemical and DNA quantification as well as structural evaluation with conventional histology and scanning electron microscopy (SEM) were performed. Compared to decellularization by CHEM alone, FTC treatment prior to CHEM was the most effective in reducing DNA while also preserving glycosaminoglycan (GAG) content. Moreover, while UBS resulted in a comparable reduction of DNA, it was the least effective in retaining GAGs. In contrast, despite the pretreatment with HHP with pressures up to 200 MPa, it was the least effective in DNA removal. Histological scoring showed that HHP scaffolds received the best score followed by UBS, FTC and CHEM scaffolds. However further analysis with SEM demonstrated a higher deterioration of the ultrastructure in UBS scaffolds. Altogether, pretreatment with FTC prior to CHEM resulted in a better balance between DNA removal and structural preservation.
