Background MicroRNAs(miRNAs)are presented in th. uterine lumen of many mammals,and in vitro experiments h.ve determined th.t several miRNAs are important for th. regulation of endometrial and troph.blast *** aim was to identify and contrast th. miRNAs present in extracellular vesicles(eVs)in th. uterine lumen fluid(ULF)at th. onset of attach.ent in cattle pregnancies(gestation d 18)initiated by artificial insemination(AI)or by th. trans-fer of an in vitro-produced blastocyst(IVP-eT).A th.rd group h.d no conceptus after th. transfer of an IVP *** Th. abundance of 263 annotated miRNAs was quantified in th. eVs collected from *** was an increase in th. transcript abundance of 20 miRNAs in th. ULF eVs from th. AI pregnant group,wh.le 4 miRNAs h.d a lower abundance relative to th. group not containing a ***,4 miRNAs were more abun-dant in ULF eVs in th. AI pregnant group relative to IVP-eT group(bta-mir-17,bta-mir-7-3,MIR7-1,MIR18A).Specific miRNAs in th. ULF eVs were co-expressed with.messenger RNAs expressed in extra-embryonic tissues and endome-trium,including genes th.t are known to be th.ir *** Th. results provide biological insigh.s into th. participation of miRNAs in th. regulation of troph.blast proliferation and differentiation,as well as in endometrium *** knowledge th.t in vitro cultured embryos can contribute to th. altered abundance of specific miRNAs in th. uterine lumen can lead to th. development of cor-rective approach.s to reduce conceptus losses during th. first month.of pregnancy in cattle.

Th. metamaterial based on external mesh.ng gears(MeG) is designed based on th. principle of external mesh.ng gear transmission. Based on th. mesh.ng transmission principle of external mesh.ng gears and planetary gear trains, th. internal and external gear rings are designed. Based on th. internal and external gear rings, th. metamaterial based on inner and outer planetary gear trains(MIP) is designed to study th. sh.ar modulus, Young's modulus, and amplitude-frequency ch.racteristics of th. metamaterial based on gears at different angles. Th. effects of th. number of planetary gears on th. ph.sical ch.racteristics of th. MIP are studied. Th. results sh.w th.t th. MeG can be continuously adjusted by adjusting th. sh.ar modulus and Young's modulus due to its mesh.ng ch.racteristics. With.th. same number of gears, th. adjustment range of th. MIP is larger th.n th. adjustment range of th. MeG. Wh.n th. number of planetary gears increases, th. adjustment range of th. MIP decreases. Moreover, wh.n th. metamaterial based on gears rotates, th. h.rmonic response ch.nges with.th. ch.nge of th. angle.

Th. study of magnetic monopoles continues to be a prominent and captivating topic in ph.sics, particularly with.n th. realm of ph.sical materials. Recently, K. C. Tan, hariom Jani, Mich.el h.gen, and th.ir collaborators (2023) reported groundbreaking discoveries, marking significant progress in th.s field. h.wever, a sense of dissatisfaction persists among research.rs regarding th. current state of advancement. To address th.s, we propose a novel th.oretical framework th.t explores magnetic monopoles th.ough.th. lens of h.ggs field portals. Our findings indicate th.t th. spin of th. magnetic monopole, s = 1, is intrinsically linked to th. fundamental expression governing its beh.vior, with.th. two aspects being inseparable in practical terms. Th.s th.ory offers a deeper understanding of th. inh.rent nature of magnetic monopoles and provides a foundation for furth.r exploration.

Dynamic stress concentration in an infinitely long cylindrical cavity due to a point sph.rical source embedded with.n a fluid-saturated poroelastic formation of infinite extent

引用

Applied Math.matics and Mech.nics(english.edition) 2025年第1期46卷 139-156页

作者： h.h.SSeINI O.BALILASh.KI Department of Mech.nical engineering Faculty of EngineeringGolestan University

Th. effects of a h.rmonically exciting monopole source on an infinitely long cylindrical cavity embedded entirely with.n a fluid-saturated poroelastic formation of infinite extent are examined th.oretically. It is assumed th.t th. source is located outside th. cavity at a specified distance from th. boreh.le axis. Th. magnitudes of th. h.op and radial stresses beside th. pore pressures exerted on th. interface and inside th. porous medium surrounding th. boreh.le are calculated and discussed. Biot's poroelastic modeling along with.th.ee types of boundary conditions for th. cylindrical interface including th. ideal fluid, empty boreh.le, and rigid inclusion with.a h.rd boundary is employed for th. analysis. Utilizing a proper translational addition th.orem for expressing th. incident sph.rical wave in terms of cylindrical wave expansions, th. proposed boundary conditions at th. interface are satisfied. Stresses are formulated by means of wave potential functions in a th.ee-dimensional(3D) manner. Th. effects of th. frequency and th. radial distance between th. source and boreh.le on th. induced stresses are examined for th. first cylindrical modes over frequency spectra. Two permeability conditions for th. interface and th.ee types of soils for th. porous formation are considered th.ough.ut th. analysis. To give an overall outline of th. study, a numerical example is presented. Th. results clearly indicate th.t th. distance is a key parameter and h.s considerable effects on th. induced stress values. In addition, th. interface permeability condition and soil ch.racteristics play an important role in determining th. dynamic response of th. boreh.le. Finally,th. obtained results are compared with.th. relevant analyses existing in th. literature for some limit cases, and good agreement is ach.eved.

Th. Red Sea-Gulf of Suez-Cairo-Alexandria Clysmic-Trend in north.rn egypt is th. main earth.uake zone in th. country, with.a moderate-to-h.gh.seismic h.zard and a h.story of significant earth.uakes caused by rifting and active faulting. To improve our understanding of th. tectonic and seismic processes in th.s area, more compreh.nsive imaging of th. crustal structure is required. Th.s can be ach.eved by increasing th. number of receiver functions (RFs) recorded by th. seismic stations in north.rn egypt and th. south.astern Mediterranean. Data h.ndling and processing sh.uld also be automated to increase process efficiency. In th.s study, we developed a capsule neural network for automated selection of RFs. Th. model was trained on a dataset containing RFs (both.selected and unselected) from five broadband stations in north.rn egypt. Stations SLM, SIWA, KOT, NBNS, and NKL are located in th. unstable sh.lf region of egypt, wh.re limited knowledge of th. deep crustal structure is available. Th. proposed capsule neural network ach.eved an average precision of 80% on th. test set. Th. automated selection of RFs using a capsule neural network h.s th. potential to significantly improve th. efficiency and accuracy of RF analysis, as demonstrated by th. stacking test. Th.s could lead to a better understanding of crustal structure and tectonic processes in north.rn egypt and th. south.astern Mediterranean.
