The lightweight encryption algorithm based on Add-Rotation-XOR(ARX)operation has attracted much attention due to its high software affinity and fast operation speed.However,lacking an effective defense scheme for physical attacks limits the applications of the ARX algorithm.The critical challenge is how to weaken the direct dependence between the physical information and the secret key of the algorithm at a low cost.This study attempts to explore how to improve its physical security in practical application scenarios by analyzing the masking countermeasures of ARX algorithms and the leakage causes.Firstly,we specify a hierarchical security framework by quantitatively evaluating the indicators based on side-channel attacks.Then,optimize the masking algorithm to achieve a trade-off balance by leveraging the software-based local masking strategies and non-full-round masking strategies.Finally,refactor the assembly instruction to improve the leaks by exploring the leakage cause at assembly instruction.To illustrate the feasibility of the proposed scheme,we further conducted a case study by designing a software-based masking method for Chaskey.The experimental results show that the proposed method can effectively weaken the impact of physical attacks.

不同于家庭现代化理论中个人主义和平等主义的亲和,夫妻关系的平等化和代际团结并存于当代的中国家庭。考察夫妻关系的平等化,需要关注行动主体、婚姻家庭中的性别差异和对差异的具体定义。在苏南地区,以家庭为单位追求对等双系权利的两头婚实践中,双方家庭通过对传统的传嗣伦理、性别文化、照料劳动、经济付出等不同价值的通约和赋值而得到一个公平的总体判断。这种公平的积极叙事中隐含个人偏好和妥协,女方家庭和部分女性需要作出更大妥协。再造的传宗接代伦理为婚姻公平带来了议价空间,但由于代际的紧密联系,亦带来了子代自主权受限的问题。随着婚姻生活日益理性化,女性经济独立和经济地位的提升,婚姻内的不确定性增长,以代际为单位寻求家庭利益最大化或成中国式亲密关系的新趋势。

We investigate the polarization properties of harmonics from the cyclic H_(3)^(2+) molecular ions in tailored bichromatic counter-rotating circularly polarized(BCCP)fields by solving the time-dependent Schrödinger equation.The allowed harmonics and their helicities are associated with the symmetry compatibility of the field-target systems,and large intensity difference between adjacent harmonics with opposite helicities appears in a wide spectral range when the BCCP field is at certain rotation angles.We try to explain the intensity difference by using a recombination model based on the quantum-orbit theory and by analyzing the ionization pathways.Moreover,to synthesize attosecond pulse trains with tunable polarization,the intensity difference is manipulated by introducing a seed XUV field,and by changing the relative amplitude ratio as well as the helicity of BCCP fields.

Background:Hepatocellular carcinoma(HCC)is one of the most prevalent cancers in the world,with a high likelihood of metastasis and a dismal prognosis.The reprogramming of glucosemetabolism is critical in the development ofHCC.TheWarburg effect has recently been confirmed to occur in a variety of cancers,including HCC.However,little is known about the molecular biological mechanisms underlying the Warburg effect in HCC cells.In this study,we sought to better understand how methyltransferase 5,N6-adenosine(METTL5)controls the development of HCC and theWarburg effect.Methods:In the current study,quantitative real-time polymerase chain reaction and Western blotting were used to detect the expression of METTL5 in HCC tissues and cell lines.Several different cell models and animal models were established to determine the role of METTL5 in glucose metabolism reprogramming and the underlying molecularmechanism of HCC.Glutathione-S-transferase pulldown,coimmunoprecipitation,RNA sequencing,non-targeted metabolomics,polysome profiling,and luciferase reporter assays were performed to investigate the molecular mechanisms of METTL5 in HCC cells.Results:We discovered that METTL5 drove glucose metabolic reprogramming to promote the proliferation and metastasis of HCC.Mechanistically,upregulation of METTL5 promoted c-Myc stability and thus activated its downstream glycolytic genes lactate dehydrogenase A(LDHA),enolase 1(ENO1),triosephosphate isomerase 1(TPI1),solute carrier family 2 member 1(SLC2A1),and pyruvate kinase M2(PKM2).The c-Box and ubiquitin binding domain(UBA)regions of ubiquitin specific peptidase 5(USP5)binded to c-Myc protein and inhibited K48-linked polyubiquitination of c-Myc.Further study revealed that METTL5 controled the USP5 translation process,which in turn regulated the ubiquitination of c-Myc.Furthermore,we identified cAMP responsive element binding protein 1(CREB1)/P300 as a critical transcriptional regulator ofMETTL5 that promoted the transcription of METTL5 in HCC.In patient-derived tumor xenograft(PDX)m

The prevalent excitonic effects in low-dimensional semiconductors enable energy-transfer-initiated photocatalytic solar-to-chemical energy conversion.However,the generally strong interactions between excitons and lattice vibrations in these low-dimensional systems lead to robust nonradiative energy loss,which inevitably impedes photocatalytic performance of energy-transfer-initiated reactions.Herein,we highlight the crucial role of engineering exciton-phonon interactions in suppressing nonradiative energy losses in low-dimensional semiconductor-based photocatalysts.By taking bismuth oxybromide(BiOBr)as an example,we demonstrate that phonon engineering could be effectively implemented by introducing Bi-Br vacancy clusters.Based on nonadiabatic molecular dynamics simulations and spectroscopic investigations,we demonstrate that the defective structure can promote exciton-low-frequency phonon coupling and reduce exciton-high-frequency optical phonon coupling.Benefiting from the tailored couplings,nonradiative decay of excitons in defective BiOBr is significantly suppressed,thereby facilitating exciton accumulation and hence energy-transfer-initiated photocatalysis.

Generation of self-generated annular magnetic fields at the rear side of a solid target driven by relativistic laser pulse is investigated by using theoretical analysis and particle-in-cell simulations.The spatial strength distribution of magnetic fields can be accurately predicted by calculating the net flow caused by the superposition of source flow and return flow of hot electrons.The theoretical model established shows good agreement with the simulation results,indicating that the magnetic-field strength scales positively to the temperature of hot electrons.This provides us a way to improve the magnetic-field generation by using a micro-structured plasma grating in front of the solid target.Compared with that for a common flat target,hot electrons can be effectively heated with the well-designed grating size,leading to a stronger magnetic field.The spatial distribution of magnetic fields can be modulated by optimizing the grating period and height as well as the incident angle of the laser pulse.
