Layered rare-earth metal oxides, harnessing the dual properties of oxides and two-dimensional layered materials, exhibit remarkable thermal stability and quantum confinement effects. Therefore, this work adopts the first-principles calculation combined with the Boltzmann transport theory to predict the thermoelectric properties of NdZnSbO compound. The coexistence of weak interlayer van der Waals interactions, robust intralayer ionic bonding, and partial covalent bonding leads to remarkable bonding heterogeneity, which engenders pronounced phonon scattering and imposes constraints on thermal transport along the out-of-plane direction. The weakened chemical bonds induced by the antibonding states, together with the rattling-like behavior of the Zn atom, culminate in the profound anharmonicity in the layered NdZnSbO compound. The weakening bond and heavy element contribute to the softness of phonon modes, which significantly diminishes the phonon group velocity. The redistribution-dominated four-phonon scattering process spans a large optical gap, which effectively reduces the lattice thermal conductivity. The NdZnSbO compound exhibits direct semiconductor characteristic with a bandgap of 0.73 e V by adopting the Heyd-Scuseria-Ernzerhof(HSE06) functional in combination with spin–orbit coupling(SOC) effect. The multi-valley feature of NdZnSbO compound augur favorably for band degeneracy, thus amplifying the power factor. Consequently, an optimal figure-of-merit(ZT) of 3.40 at 900 K is achieved for the n-type NdZnSbO compound. The present study delves deeply insights into the origins for the low thermal conductivity of NdZnSbO compound and proposes an optimization scheme to enhance overall thermoelectric performance.

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.

孔子对自己有过一个评价:'其为人也,发愤忘食,乐以忘忧,不知老之将至云尔.'学习可以'忘食'、'忘忧',在孔子看来,学习之乐,乐莫大焉.每次当我去拜望徐北文先生的时候,我总会想起这句话,见到手不释卷、坐拥书城的先生,我知道先生是真正体味到'学而时习之,不亦说乎'之真意的人.北文先生曾将人们耳熟能详的那句'书山有路勤为径,学海无涯苦作舟'中的'苦'字,改为'乐'字,他在一篇文章中曾写道:一个人一旦有了一种强烈的求知的欲望,学习对他来说就不会再是一种负担,当然也就不再是一种苦了,因为在读书学习的过程中,通过他不断的努力、如饥似渴的钻研,问题一旦获得解答,他才会'如醍醐灌顶,如宝光乍现,感到无比的快乐.

吴义勤认为,刘玉栋的写作给人厚实、稳重、沉静的感觉。他是一个乡土小说家,“乡土的道德化”是他的价值支撑,也是他的叙事策略。他的乡土情结隐藏着深刻悖论,既对乡村的纯朴人性和伦理情怀满含敬意,又不能不正视乡村道德日益颓败和沦落的现实。这种情感和价值观的矛盾构成他小说的内在张力。洪治纲认为,刘玉栋的小说充满温暖的情感之力。他以一种温情式的话语基调,朴实平和地叙述着社会底层人群的生存故事,在悲剧性氛围里发掘种种人性的光辉,凸现人格尊严的力量,寻找内心温暖的亮光。其创作已形成自己特有的审美格调。石万鹏认为,刘玉栋的小说展示了个人化的历史记忆和普遍化的童年经验,表达了他对乡村生活和乡村文化的理解感悟,以及对现代化进程的思考与忧虑。其创作呈现出一种忧伤的诗性和抒情品质。
