针对原始的白鲸算法(beluga whale optimization,BWO)在某些情况下,中后期的探索和开发能力不足、多样性和求解精度降低、容易陷入局部最优等问题,提出一种基于混沌反向学习和水波算法改进的白鲸优化算法(TWBWO),进一步提高白鲸算法的计算精度和收敛速度,增强全局搜索和跳出局部最优能力。结合混沌映射和反向学习策略提高种群的质量和多样性,加快收敛速度。引入水波算法(water wave optimization,WWO)的折射操作,避免寻优时轻易陷入局部最优,提高计算精度。实验结果表明,TWBWO算法较之原始算法和其他经典算法在收敛速度和求解精度以及稳定性方面更为优秀,性能和寻优能力更强。

Security analysis of public-key cryptosystems is of fundamental significance for both theoretical research and applications in cryptography. In particular, the security of widely used public-key cryptosystems merits deep research to protect against new types of attacks. It is therefore highly meaningful to research cryptanalysis in the quantum computing environment. Shor proposed a wellknown factoring algorithm by finding the prime factors of a number n =pq, which is exponentially faster than the best known classical algorithm. The idea behind Shor's quantum factoring algorithm is a straightforward programming consequence of the following proposition: to factor n, it suffices to find the order r; once such an r is found, one can compute gcd( a^(r/2) ±1, n)=p or q. For odd values of r it is assumed that the factors of n cannot be found(since a^(r/2) is not generally an integer). That is, the order r must be even. This restriction can be removed, however, by working from another angle. Based on the quantum inverse Fourier transform and phase estimation, this paper presents a new polynomial-time quantum algorithm for breaking RSA, without explicitly factoring the modulus n. The probability of success of the new algorithm is greater than 4φ( r)/π~2 r, exceeding that of the existing quantum algorithm forattacking RSA based on factorization. In constrast to the existing quantum algorithm for attacking RSA, the order r of the fixed point C for RSA does not need to be even. It changed the practices that cryptanalysts try to recover the private-key, directly from recovering the plaintext M to start, a ciphertext-only attack attacking RSA is proposed.

帕金森病(PD)多发于老年人群,随着病情逐渐进展,对PD患者的运动功能和非运动功能影响巨大。目前PD的主要治疗是药物治疗,但长期服用会产生不良反应,寻找更安全有效的治疗方法十分必要。微生物-脑-肠轴(MGBA)是连接中枢神经系统与消化系统的通道,在PD发病机制中发挥重要作用。文章主要就肠道菌群、脑肠肽和下丘脑-垂体-肾上腺轴对PD的影响,以及基于MGBA理论对PD的治疗现状等进行综述。

胎儿生长受限(fetal growth restriction,FGR)是一种常见的产科疾病,其可导致新生儿低出生体质量和出生后肌肉量减少。这可能与肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)和白细胞介素-6(interleukin-6,IL-6)的调控密切相关。研究发现,这两种炎症因子在FGR胎儿中表达水平异常,可通过影响成肌细胞的增殖和分化,干扰正常骨骼肌的发育。此外,TNF-α与IL-6还可以激活特定的信号通路,如核因子κB(nuclear factor-κB,NF-κB)、Janus激酶/信号转导及转录活化因子(Janus kinase/signal transducer and activator of transcription,JAK/STAT)、丝裂原激活的蛋白激酶(mitogen-activated protein kinase,MAPK)等信号通路,调节肌细胞的代谢和功能。如使用特定的抗炎药物或生物制剂来降低TNF-α和IL-6的活性,可能有助于改善FGR胎儿的骨骼肌发育。总的来说,TNF-α和IL-6在FGR胎儿骨骼肌发育中的作用是一个多层面、复杂的过程,需要进一步的深入研究来阐明其具体机制,帮助理解FGR的病理生理学,并为治疗FGR胎儿提供新的思路。

系统性探寻耕地撂荒现象,有助于因地制宜地稳步拓展农业生产空间。基于全国346个代表性山区县的抽样调查,本文利用空间分析和分层线性模型等方法,系统揭示不同类型耕地撂荒的时序、规模、空间分异特征及其决定因素,以期为分类推进撂荒地治理提供科学依据。研究发现:不同类型耕地的撂荒时间节点存在显著差异,坡耕地、旱作梯田、水作梯田、平地水田和平地旱地依次撂荒,耕作条件较差的耕地更早遭遇撂荒,特别是坡耕地自20世纪80年代起就开始撂荒。目前,26.64%的农户经历过耕地撂荒,撂荒耕地的面积占比达到9.88%,呈现出“南高北低”的空间分布特征。水田撂荒主要集中在东南沿海,而坡耕地和旱地则多发于黄土高原、东南沿海和西南山区。撂荒情况受村落和农户特征影响,这两个层面分别对撂荒变异解释了44.83%和55.17%。从事非农工作、年长及身体状况较差的农户更可能撂荒耕地;同时,遭受野生动物侵害、土地细碎化严重且灌溉条件不佳的区域更易撂荒。劳动力成本的持续上升压缩了农业收益,使得农户种粮收益偏低,旱作梯田甚至面临亏损。因此,撂荒地的治理应聚焦坡耕地和梯田,政府应积极推动土地流转与整治,普及适合丘陵山区的小型机械,以降低耕地经营成本,提高农耕效益。
