TL;DR: Pulsatile GnRH therapy is a well-tolerated and effective therapy for the induction of spermatogenesis in some men with idiopathic hypog onadotropic hypogonadism, and it appears that a significant fraction of them should be treated for a minimum of 1–2 years to maximize testicular growth and achieve sperMatogenesis.

TL;DR: In this paper, a strip reduction test was conducted with tools provided with shallow, longitudinal pockets oriented perpendicular to the sliding direction, and the experiments reveal that the distance between pockets should be larger than the pocket width, thereby creating a topography similar to flat table mountains to avoid mechanical interlocking in the valleys; otherwise, an increase in drawing load and pick-up on the tools are observed.

TL;DR: In this paper, a Strip Reduction Test (SRT) is proposed for industrial ironing processes that is capable of replicating the highly severe tribological conditions that are experienced during both the forward stroke and the backward retraction of the punch.

TL;DR: This paper presents a multi-modal obstacle and environment detection and recognition approach for process evaluation in agricultural fields that detects and maps static and dynamic obstacles globally, while providing process-relevant information along the traversed trajectory.
