Separate Analysis of Remote Sensing Information of Structures of Different Geological Periods and Quantitative Study of Corresponding Tectonic Stress Fields

The structural feature shown on a remote sensing image is a synthetic result ofcombination of the deformations produced during the entire geological history of an area.Therefore, the respective tectonic stress field of each of the different stages in the complexdeformation of an area can be reconstructed in three steps: (1) geological structures formed atdifferent times are distinguished in remote sensing image interpretation; (2) structuraldeformation fields at different stages are determined by analyzing relationships betweenmicrostructures (joints and fractures) and the related structures (folds and faults); and (3)tectonic stress fields at different stages are respectively recovered through a study of the featuresof structural deformation fields in different periods. Circular structures and related circlular and radial joints are correlated in space to con-cealed structural rises. The authors propose a new method for establishing a natural model ofthe concealed structural rises and calculating the tectonic stress field by using quantitative dataof the remote sensing information of circular structures and related linear structures.

Modelling and analysis of circular bimorph piezoelectric actuator for deformable mirror

A theoretical model of a circular flexure-mode piezoelectric bimorph ac- tuator is established. The circular bimorph structure, consisting of two flexible layers of piezoelectric material and a layer of metallic material in the middle, is powered to the flexural deformation. The analytical solutions including the statics solution and the dynamics solution are derived from the 3D equations of the linear theory of piezoelectric- ity. Numerical results are included to show the circular bimorph piezoelectric actuator （CBPA） performance, depending on the physical parameters.

Y-Shaped Circular Aptamer–DNAzyme Conjugates for Highly Efficient in Vivo Gene Silencing

Oligonucleotide drugs have been used widely as therapeutic agents for gene therapy,while their instability in biological media and inefficiency for intracellular delivery remain major hurdles for practical in vivo applications.Herein,we report a circular Y-shaped aptamer–DNAzyme conjugate(cYAD)for highly efficient in vivo gene silencing via RNA cleavage,which can been employed in various disease treatments,including cancer,inflammation,as well as viral infections.Systematic studies revealed that cyclization of the DNA structure could improve the stability of oligonucleotide drugs in vivo.Besides,the bivalent aptamer motifs provided a specific and enhanced tumor cell targeting ability for accumulation and retention of the oligonucleotide drugs at the tumor site.As a proof of concept,a widely applicable Na+-dependent fluorescent sensor,NaA43 DNAzyme,was used to inhibit MET gene expression in mice tumor model tissues,which exhibited highly efficient gene silencing performance in vivo,which confirmed our findings with cYAD.This strategy provides a novel approach for the construction of oligonucleotide drugs for practical therapeutic applications.
