Adversarial distillation(AD)has emerged as a potential solution to tackle the challenging optimization problem of loss with hard labels in adversarial training.However,fixed sample-agnostic and student-egocentric attack strategies are unsuitable for distillation.Additionally,the reliability of guidance from static teachers diminishes as target models become more robust.This paper proposes an AD method called Learnable Distillation Attack Strategies and Evolvable Teachers Adversarial Distillation(LDAS&ET-AD).Firstly,a learnable distillation attack strategies generating mechanism is developed to automatically generate sample-dependent attack strategies tailored for distillation.A strategy model is introduced to produce attack strategies that enable adversarial examples(AEs)to be created in areas where the target model significantly diverges from the teachers by competing with the target model in minimizing or maximizing the AD loss.Secondly,a teacher evolution strategy is introduced to enhance the reliability and effectiveness of knowledge in improving the generalization performance of the target model.By calculating the experimentally updated target model’s validation performance on both clean samples and AEs,the impact of distillation from each training sample and AE on the target model’s generalization and robustness abilities is assessed to serve as feedback to fine-tune standard and robust teachers accordingly.Experiments evaluate the performance of LDAS&ET-AD against different adversarial attacks on the CIFAR-10 and CIFAR-100 datasets.The experimental results demonstrate that the proposed method achieves a robust precision of 45.39%and 42.63%against AutoAttack(AA)on the CIFAR-10 dataset for ResNet-18 and MobileNet-V2,respectively,marking an improvement of 2.31%and 3.49%over the baseline method.In comparison to state-of-the-art adversarial defense techniques,our method surpasses Introspective Adversarial Distillation,the top-performing method in terms of robustness under AA attack for the CIFAR-10 dataset,with enhancements of 1.40%and 1.43%for ResNet-18 and MobileNet-V2,respectively.These findings demonstrate the effectiveness of our proposed method in enhancing the robustness of deep learning networks(DNNs)against prevalent adversarial attacks when compared to other competing methods.In conclusion,LDAS&ET-AD provides reliable and informative soft labels to one of the most promising defense methods,AT,alleviating the limitations of untrusted teachers and unsuitable AEs in existing AD techniques.We hope this paper promotes the development of DNNs in real-world trust-sensitive fields and helps ensure a more secure and dependable future for artificial intelligence systems. 展开更多

The Science teachers in primary schools are the key group in developing science education, and they play a vital role in realizing the dream of strengthening the country through education. Their professional happiness deserves special attention. Whether this group is happy not only affects their own working conditions and quality of life, but also affects the work vitality of other teachers. Improving the professional happiness of science teachers in primary schools has become an important topic in the construction of teachers’ team in the new period. At present, the intensity of primary school science teachers’ own work is high, their non-own work is increasing, their physical and mental health is difficult to guarantee, and their professional happiness is reduced. The main causes of the problems are poor individual psychological quality, poor school management style and improper social cognitive evaluation. In order to solve this problem, we have explored strategies to improve the professional happiness of science teachers in primary schools through reshaping teachers’ work, democratic management of schools and national policy guarantee. 展开更多

Empirical descriptions of how the teacher performs requests in English can make them realize the importance of improving pragmatic competence, so that they could help students develop more native-like pragmatic behaviors and enhance cultural competence. This case study is to explore the pragmatic competence of a Chinese EFL teacher by investigating the patterns of realization strategies and the ways of reacting to the different social and contextual variables in her requests. It was found out that the teacher investigated in the study had good pragmatic awareness and pragmatic competence to produce the speech act of requests and develop students' pragmatic competence, but more explicit instructions should be provided to help students develop more native-like speech acts by providing more explicit instructions. 展开更多

Apparent critical current density(j_(Ac)^(a))of garnet all-solid-state lithium metal symmetric cells(ASSLSCs)is a fundamental parameter for designing all-solid-state lithium metal batteries.Nevertheless,how much the possible maximum apparent current density that a given ASSLSC system can endure and how to reveal this potential still require study.Herein,a capacity perturbation strategy aiming to better measure the possible maximum j_(Ac)^(a)is proposed for the first time.With garnet-based plane-surface structure ASSLSCs as an exemplification,the j_(Ac)^(a)is quite small when the capacity is dramatically large.Under a perturbed capacity of 0.001 mA h cm^(-2),the j_(Ac)^(a)is determined to be as high as 2.35 mA cm^(-2)at room temperature.This investigation demonstrates that the capacity perturbation strategy is a feasible strategy for measuring the possible maximum j_(Ac)^(a)of Li/solid electrolyte interface,and hopefully provides good references to explore the critical current density of other types of electrochemical systems. 展开更多

It is also the important symbol of the improvementof overall quality of nursing teachers. In recent years, educational circles pay more and more attention to the cultivationof students’ CT ability, take CT and solve the problem as two basic skills of thinking. In the early 1980s, critical societytheory was led into the nursing field. After years of development, CT has become one of research hotspots in today’sinternational nursing. Numerous studies had confirmed that the CT played a significant role in nursing education, clinicalpractice and nursing scientific research. The paper studied the whole status and characteristics of CT emotional tendencyof college nursing teachers, and analyzed potential cause and discussed deeply on the corresponding factors of how toimprove college nursing teachers’ teaching ability and scientific ability. This research adopted random sampling method,in which questionnaires were distributed among some nursing teachers in six universities and 97 nursing teachers. Thestatistical results indicated that nursing teachers had a positive performance towards CT emotional tendency, but notstrong positive, and there were statistical significance among nursing teachers with different age, different length ofservice and reading habit (all P〈0.05). In a conclusion, the managers of universities should lay stress on the importanceof critical thinking, and provide the development space to enhance the nursing teachers’ CT ability and offer betterservices for nursing student. 展开更多
