Noether conserved quantities and Lie point symmetries of difference Lagrange-Maxwell equations and lattices

This paper presents a method to find Noether-type conserved quantities and Lie point symmetries for discrete mechanico-electrical dynamical systems,which leave invuriant the set of solutions of the corresponding difference scheme. This approach makes it possible to devise techniques for solving the Lagrange Maxwell equations in differences which correspond to mechanico-electrical systems,by adapting existing differential equations.In particular,it obtains a new systematic method to determine both the one-parameter Lie groups and the discrete Noether conserved quantities of Lie point symmetries for mechanico-electrical systems.As an application,it obtains the Lie point symmetries and the conserved quantities for the difference equation of a model that represents a capacitor microphone.

A Complex Higher-Dimensional Lie Algebra with Real and Imaginary Structure Constants as Well as Its Decomposition

A new Lie algebra G of the Lie algebra sl（2） is constructed with complex entries whose structure constants are real and imaginary numbers. A loop algebra G corresponding to the Lie algebra G is constructed, for which it is devoted to generating a soliton hierarchy of evolution equations under the framework of generalized zero curvature equation which is derived from the compatibility of the isospectral problems expressed by Hirota operators. Finally, we decompose the Lie algebra G to obtain the subalgebras G1 and G2. Using the G2 and its one type of loop algebra G2, a Liouville integrable soliton hierarchy is obtained, furthermore, we obtain its bi-Hamiltonian structure by employing the quadratic-form identity.

Convection of Maxwell fluid over stretching porous surface with heat source/sink in presence of nanoparticles:Lie group analysis

The convection of a Maxwell fluid over a stretching porous surface with a heat source/sink in the presence of nanoparticles is investigated. The Lie symmetry group transformations are used to convert the boundary layer equations into coupled nonlinear ordinary differential equations. The ordinary differential equations are solved numerically by the Bvp4c with MATLAB, which is a collocation method equivalent to the fourth-order mono-implicit Runge-Kutta method. Furthermore, more attention is paid to the effects of the physical parameters, especially the parameters related to nanoparticles, on the temperature and concentration distributions with consideration of permeability and the heat source/sink.

Hyaluronic acid injection in the auricular base for the aesthetic correction of lying ears:A retrospective study

Background Ears play an important role in facial profiles.Lying ears are not perceived favorably in Asian cultures;therefore,surgical procedures are implemented to adjust this defect.However,surgery has complications and requires recovery time.We introduced a hyaluronic acid(HA)injection technique to aesthetically improve ear prominence.Methods This retrospective study examined 25 Chinese patients aged 20-47 years with congenital lying ears who received HA injections in the auricular base at Shanghai Ninth People’s Hospital and Hangzhou Yijie Medical Cosmetology Clinic between November 2019 and December 2022.The average injection volume was 6.32±1.22 mL in the auricular base unilaterally,and the follow-up time ranged from 6 to 24 months.Morphological measurement data were recorded.Two-dimensional(2D)and three-dimensional(3D)images were obtained to evaluate the effects.Results All patients showed improvements in ear prominence.The cranioauricular angle(CAA)increased from 22.24°±4.53°to 65.90°±5.38°immediately post-injection and was maintained at 49.18°±4.74°6 months later.The ear projection(EP)increased from 14.75±2.72 mm to 26.26±2.94 mm immediately post-injection and was 22.51±2.68 mm after 6 months.No serious complications were noted.Conclusion HA injection in the auricular base effectively corrected the lying ears and aesthetically optimized the facial profile.It also had a face-lift effect that made the face look younger and more compact.The injection procedure was minimally invasive and required no recovery period.The effect was maintained for a long time and was satisfactory.

Educational Innovation in Lying Flat Phenomenon-A Case Study of the Balinese Teaching Experience

Lying flat(Tang Ping)is a prevalent way of life in contemporary countries throughout the world.It is an avoidance behavior chosen by individuals in response to limited social resources and ongoing harsh social competition.Previous studies have demonstrated that the phenomena of“lying flat”has a major negative effect on student learning.In order to investigate the impact of educational innovation on the phenomenon of“lying flat”,we will observe students’learning behaviors under the traditional education model and innovative teaching methods in our Bali teaching practice to determine the causes of“lying flat”and the means to improve educational innovation.The study found that“lying flat”is caused not just by students’discontent with their level difference,but also by the conflict between external resources and internal pressure.In addition,educational reforms on three levels,including further stratified education,strengthening teacher education and promoting effective communication between students and teachers,and employing online resources to promote students’interest in learning,can ameliorate the phenomenon of pupils“lying flat”.This study contends that educational innovation can have a positive effect on the phenomena of“lying flat”.

Internal Contradictions of Wilde’s Aestheticism——On The Decay of Lying

The Decay of Lying,one of Wilde’s famous critic dialogues,is a demonstration of his aesthetic opinions,such as Art is telling lies,Life imitates art etc,which gives full expression of his pursue of art’s purity and independence.Wilde absolutely takes the side of art and is against the forced interference of art as the subject by politics,utilitarianism,morality and ethics,against the erosion of the artistic realm of beauty by over-realness,against taking the form of art as the accessory to certain content or subject.However,Wilde totally isolates art from reality by putting them in the position of dual antithesis,and this is the root of the internal contradictions in his Aestheticism.This essay aims to discuss the contradictions from four aspects:contradiction between art and real life,art and morality,art and truth and then contradiction between art’s form and content,so as to get a better understanding and correct evaluation of Wilde and his aestheticism.

Underlying Mechanisms of p53-independent Apoptosis Induced by Heavy Ion Irradiation in Cancer Cells

Radiotherapy is widely used for the definitive and adjuvant treatment of numerous cancers[1].However,resistance to radiotherapy remains an important concern[2].Various factors including p53 mutation or deletion[3],overexpression of DNA repair proteins[4],and tumor microenvironment[5]have been proposed to play roles in radioresistance.Among the radioresistant factors,p53 mutation or deletion is regarded as a good candidate for radioresistant markers[6].The tumor suppressor p53 is well established as the guardian of the genome,regulating cell cycle arrest,DNA repair,senescence,and apoptosis[7].Mutation of p53 occurs in more than 50%of human cancers,which significantly increases cellular resistance to-irradiation[8].Additionally,there is growing evidence that mutation or deletion of p53 tumors cells is inherently resistant to radiation and perhaps other conventional anticancer treatments,i.e.,chemotherapy[9].This intrinsic mechanism of resistance is responsible for a significant number of tumor recurrences[10].

LDNet: A Robust Hybrid Approach for Lie Detection Using Deep Learning Techniques

Deception detection is regarded as a concern for everyone in their daily lives and affects social interactions.The human face is a rich source of data that offers trustworthy markers of deception.The deception or lie detection systems are non-intrusive,cost-effective,and mobile by identifying facial expressions.Over the last decade,numerous studies have been conducted on deception detection using several advanced techniques.Researchers have focused their attention on inventing more effective and efficient solutions for the detection of deception.So,it could be challenging to spot trends,practical approaches,gaps,and chances for contribution.However,there are still a lot of opportunities for innovative deception detection methods.Therefore,we used a variety of machine learning(ML)and deep learning(DL)approaches to experiment with this work.This research aims to do the following:(i)review and analyze the current lie detection(LD)systems;(ii)create a dataset;(iii)use several ML and DL techniques to identify lying;and(iv)create a hybrid model known as LDNet.By combining layers from Vgg16 and DeneseNet121,LDNet was developed and offered the best accuracy(99.50%)of all the models.Our developed hybrid model is a great addition that significantly advances the study of LD.The findings from this research endeavor are expected to advance our understanding of the effectiveness of ML and DL techniques in LD.Furthermore,it has significant practical applications in diverse domains such as security,law enforcement,border control,organizations,and investigation cases where accurate lie detection is paramount.
