In this work, an elegant method is proposed to derive the thermoelastic field in- duced by thermomechanical loadings in a decagonal quasicrystalline composite composed of an infinite matrix reinforced by an elliptical inclusion. The thermomechanical loadings include a uniform temperature change, remote uniform in-plane heat fluxes and remote uniform in-plane stresses. The corresponding boundary value problem is ultimately reduced to the solution of two independent sets of four coupled linear algebraic equations, each of which involves four complex constants characterizing the internal stress field. The solution demonstrates that a uniform tem- perature change and remote uniform stresses will induce an internal uniform stress field, and that uniform heat fluxes will result in a linearly distributed internal stress field within the elliptical inclusion. The induced uniform rigid body rotation within the inclusion is given explicitly.

Introduction of the treatment concept:Regular deep brain stimulation(rDBS)is the standard therapy for the treatment of medically refractory Parkinson’s disease(PD)(Benabid et al.,2009).Notwithstanding its significant therapeutic effects,rDBS may cause side effects,characterized as rDBSinduced movement disorders(BaizabalCarvallo and Jankovic,2016).

Oro clines are map-view bends of the Earth’s lithosphere formed by rotation of originally quasilinear linear rock units about a sub-vertical axis [1].They can have amplitudes and wavelengths on the order of hundreds of kilometres and are a significant feature of many active and ancient mountain belts(Fig.1,*** orocline,Bolivian orocline,Betic-Rif Belt,

Obstructive azoospermia secondary to epididymal obstruction can be corrected by microsurgical reconstruction with vasoepididymostomy （VE）. Although alternative management such as epididymal or testicular sperm aspiration in conjunction with intracytoplasmic sperm injection is feasible, various studies have established the superior cost-effectiveness of VE as a treatment of choice. Microsurgical VE is considered one of the most technically challenging microsurgeries. Its success rate is highly dependent on the skills and experience of the surgeons. Various techniques have been described in the literature for VE. We have pioneered a technique known as longitudinal intussusception VE （LIVE） in which the epididymal tubule is opened longitudinally to obtain a larger opening to allow its tubular content to pass through the anastomosis. Our preliminary data demonstrated a patency rate of over 90%. This technique has been widely referenced in the recent literature including robotic-assisted microsurgery. The history of the development of different VE approaches, the oreoDerative evaluation along with the techniaues of various VE will be described in this article.
