Summary of main observation and conclusion: Here we report the design and fabrication of high‐performance pressure sensors based on three‐ dimensional (3D) graphene foam filled polydimethylsiloxane (GF@PDMS) composite with a broad sensing range spaning from 0.05 kPa to 130 kPa. The interpretation of device functioning mechanism can be classified into low and high pressure sensing regions. In the low pressure region (mechanical vibration signals, as well as physiology vibrational signals generated by human throats. We expect this technology could be integrated into different sensing systems for the applications in wearable smart electronics and human‐machine communications. [ABSTRACT FROM AUTHOR]

Since ancient times, man has been concerned to create an artificial structure similar to itself. This concern has remained constant attention and creative thinkers most profound since antiquity until today, it is of greatest interest. This article aims to highlight the most significant moments of the evolution from mechanical creatures mythical or real, from antiquity to the present humanoid robots. There are thus shown the most significant variants humanoid imagined or realized since Talos, described in Greek mythology, continuing with mechanical machines during late Roman Empire, the Byzantine Empire and then the Renaissance of the post-renaissance, then they are shown the main achievements of the industrialization period from the nineteenth to the early part of the twentieth century, then to the most important made in the last decades of the twentieth century and early twenty-first century. The work is important to stimulate concerns academic theorists and practice but also in the industrial practice specializing in robotics and more generally in mechatronics. It also opens the prospect of defining the concept of an artificial humanoid useful both for human prosthesis with certain disabilities, and a humanoid robot performance.

＜正＞This paper presents a joint system called the "multilink spherical joint", which is a novel mechanism that allows tri-axial rotation of members. It can form ideal structure systems of variable geometry without small offsets between the rotation centers of the links. We also propose an analytical method for finding the shape of these structures in unstable states. The method is based on a combination of the stabilizing process and the steepest descent method. The proposed method was compared with the other two methods, and found to be optimal for numerical analysis with a fixed tolerance.

Nanotechnology is briefly a science field searching substances having superior properties at nano-scale (different optical, mechanical and thermal properties) and those to be potentially produced in the future from these substances. Accordingly, it is a technology regarding opportunities providing the development during the formation of new products not applicable in advance and the formation of new processes. This technology that has the potential of affecting the world economy is at the development stage just now and it is thought that it will cause high changes in human life in the future 15-20 years. Nanotechnology provides an opportunity bringing new technological developments and applications appeared as impossible before as well as bringing a new perspective for available technological processes. In the context of the report in the light of mentioned information, brief information was given on the place and use of nanotechnology in fields such as systems of drug delivery, diagnosis of diseases, vaccine development, treatment of diseases, improvement of fertility functions of animals, determination of fertility capabilities of animals, store of gametes and embryos by freezing, animal breeding, farm medicine, meat and meat production, food safety, and neutralization of animals as use areas in veterinary medicine. Furthermore, in our country and the world, knowledge regarding the intended use of nano-technology based drugs used in veterinary medicine was presented in Table 1.
